The Teachings Of Peace And Islam - 1755 Words

The teachings of peace in Islam and Christianity are evident in the development of inner peace for the individual. Peace is not just the nonexistence of violence, conflict or war but encompasses a larger concept of factors such as healthy interpersonal or international relationships and social or economic wellbeing. Peace would be best understood as more a continuous goal rather than a fundamental fact. This implies that everlasting peace is united with religion. For both Christianity and Islam, inner peace is found by faithfully devoting one’s self to the will of God. These religions don’t just allow the individual to achieve inner peace, but also enable the individual to live at peace with others. The individual adherent is guided by the expressions of religious beliefs, to achieve/experience inner peace. Achieving peace is a core foundation to the Christian religion. Christians are able to achieve inner peace as a result of the salvation won through the death, resurrection and ascension of Jesus Christ. However for Christians to attain the peace offered by Jesus’ sacrifice, they must devote their lives according to his teachings and become his disciple. Jesus’s teachings are drawn primarily from the New Testament in the Christian bible - the foundational source of teaching for all Christians.

Health Hazards of Using Excessive Computers Free Essays

Computers are very important and help us in many ways but they can also cause us problems. Some of the problems are,backache which is caused by improper sitting posture and can be prevented by sitting upright with your back resting on the backrest chair. The other problem is eye strain which can be caused by radiations emitted by the monitor and can be prevented by regulating the amount of light from the monitor and avoid using a flickering monitor. We will write a custom essay sample on Health Hazards of Using Excessive Computers or any similar topic only for you Order Now A neck ache is caused by putting the monitor above the eye level and can be avoided by positioning your monitor on the same level with your eyes. The Risks With the increase in computer use, a number of health and safety concerns related to vision and body aches and pains have arisen. Many problems with computer use are temporary and can be resolved by adopting simple corrective action. Most problems related to computer use are completely preventable. However it is important to seek prompt medical attention if you do experience symptoms including: * continual or recurring discomfort * aches and pains * throbbing * tingling numbness * burning sensation * or stiffness Seek help even if symptoms occur when you are not working at your computer. Laptop computers can present particular problems due to small screens, keyboards and inbuilt pointing devices (e. g. a small portable mouse or touchpad). Prolonged use of laptops should be avoided. If using a laptop as a main computer (i. e. use as a normal desktop computer in addition to use as a portable), it is advisable to use the laptop with a docking station. This allows an ordinary mouse, keyboard and monitor to be used with the laptop. The main risks associated with using computers include: * Musculoskeletal problems * Eye strain and a greater awareness of existing eye problems Rashes and other skin complaints have also been reported, although it is thought these are caused by the dry atmosphere and static electricity associated with display units rather then by the display units themselves. There are potential risks from radiation though this is a contentious area. Musculoskeletal problems These can range from general aches and pains to more serious problems and include: * Upper limb disorders such as repetitive strain injury (RSI) tenosynovitis and carpal tunnel syndrome – by far the most important as it can quickly lead to permanent incapacity * Back and neck pain and discomfort * Tension stress headaches and related ailments These types of problem can be caused by: * Maintaining an unnatural or unhealthy posture while using the computer * Inadequate lower back support * Sitting in the same position for an extended period of time * An ergonomically poor workstation set up Eye strain Computer users can experience a number of symptoms related to vision including: * Visual fatigue * Blurred or double vision * Burning and watering eyes * Headaches and frequent changes in prescription glasses Computer work hasn’t been proven to cause permanent eye damage, but the temporary discomfort that may occur can reduce productivity, cause lost work time and reduce job satisfaction. Eye problems are usually the result of visual fatigue or glare from bright windows or strong light sources, light reflecting off the display screen or poor display screen contrast.

Hammurabi and Alexander the Great Essay Example For Students

Hammurabi and Alexander the Great Essay Hammurabi, Zhou, Asoka the Great, and Alexander the Great had various means by which they justified their authority and their rule. Each had a very unique style of thoughts and actions. History was changed due to the actions of these rulers. The Zhou was a coalition of several groups that existed during the Shang dynasty. Zhou believed that the Shang failed to uphold religious duties, therefore they attributed their victory over Shang to the Mandate of Heaven. This empire was the longest empire in Chinese civilization. Iron made its first appearance during this period. Enormous armies of foot soldiers armed with iron swords and shields replaced old chariot style warfare. Commerce expanded and population grew. The Zhou believed that to retain loyalty of nobility, they must grant the nobility a certain amount of land. Hammarubi justified authority by his code of laws. He was king of Babylon during the first Babylonian Empire. This Empire extended from the Tigris and Euphrates and westward to the Mediterranean Sea. Hammarubi supervised irrigation, agriculture, tax collection, and construction of many buildings. He was best known for his codification of Babylonian law. The codes of Hammurabi are the earliest legal code known. The laws seek to protect the poor, women, children, and slaves. It is from this code of laws that we get the punishment idea of an eye for an eye. Asoka the Great was the son of a Mauryan King. At age eighteen he became vice-roy. In the year 273 he inherited his fathers thrown. During the Kalinga revolt, he realized that the bloodshed was far too great for him to handle. He hung up his sword and converted to Buddhism. Asokas power allowed him to promote his principle as the law of the land. Asoka scraped codes into rock pillars that talked about conforming to Dharma. Asoka the Great did not allow capital punishment. He was most responsible for the exploration of Buddhism to areas such as China and Asia Minor. Alexander the Great was one of the greatest military minds of all times. He was King of Macedonia and conqueror of the Persian Empire. Aristotle taught Alexander about the Iliad and other classic novels. In a single week Alexander crushed Illyrians and Thebes, which had revolted. He took the cities by storm and spared only the temples of gods and the house of a poet. He began war against Persia in 334 with an army of Macedonian and Greek troops. Alexander founded a number of cities, most named Alexandria. These cities were well located, well paved, and were provided with good water supplies. Greek culture was introduced during the period of Alexanders reign. It was during this time that the Greek language became widely known. Alexander the Great extended the influence of Greek civilization and prepared the way for the conquest of the Roman Empire. Zhou, Asoka the Great, Hammurabi, and Alexander the Great played important roles in the history of the world. Each ruler had their own ideas and beliefs, but all of them had their way of ruling the land. As you can see, The four leaders had different ways of justifying their rule. History .

Why Levitt’s Analysis is Awry Essay Example

Why Levitt’s Analysis is Awry Essay In chapter 3 of Freakonomics by Steven D. Levitt and Stephen J. Dubner, Levitt demonstrates how false predictions are often led by conventional wisdom and why drug dealers still live with their moms. I agree with the author that conventional wisdom is often wrong or plainly insufficient to answer many important questions.   Crime did not keep on soaring in the 1990s, money alone does not help politicians win elections, and drinking eight glasses of water a day has never actually been shown to do a thing for one’s health.   Conventional wisdom is often shoddily formed and devilishly difficult to see through as it is associated closely with confusion of association and causation and also fallacy of composition.   While it is true that a healthy person may drink eight glasses of water each day, it does not necessarily mean that drinking eight glasses of water a day is good for one’s health.   Association and causation are entirely different.   Just like smoking cigarettes does not necessarily cause cancer – simply because two events are associated (in time, for example), it does not necessarily follow that one is the cause and the other is the effect.à ‚   People often confuse association and causation become it is convenient to assume that the apparent, easy answers are the correct ones.   The erroneous view that what is good or true for the individual is necessarily good or true for the group is another example of conventional wisdom that cannot be explained by reality in all its manifestations.   All the same, it is very convenient for people to just accept conventional wisdom, especially while the media and advertisement are also enforcing it.   This is one of the reasons why most people in the world do not turn into scientists. We will write a custom essay sample on Why Levitt’s Analysis is Awry specifically for you for only $16.38 $13.9/page Order now We will write a custom essay sample on Why Levitt’s Analysis is Awry specifically for you FOR ONLY $16.38 $13.9/page Hire Writer We will write a custom essay sample on Why Levitt’s Analysis is Awry specifically for you FOR ONLY $16.38 $13.9/page Hire Writer Indeed, it is possible to analyze the truth or untruth of conventional wisdom by asking the right questions.   There even exists a basic procedure that is used in many scientific works to avoid conventional wisdom in building and testing theories.   The procedure follows a set of guidelines.   First, the researcher decides what it is that he or she wants to explain or predict.   Second, the researcher identifies the variables that he or she believes are important to what he or she would like to explain or predict.   Third, the assumptions of the theory must be stated.   Fourth, the hypothesis must be stated.   Fifth, the theory must be tested by comparing its predictions against real-world events.   Sixth, it is recognized that if the evidence supports the theory, no further action is necessary, although it is a good idea to continue to examine the theory closely.   Seventh, if the evidence rejects the theory, the researcher must either formulate a new theory or ame nd the old theory in terms of its variables, assumptions, and hypothesis.   As an example, a researcher may have predicted that the housing market would experience a boom in the coming years.   If this does not happen, he or she is required to change the old theory or create a new one altogether.   But it if happens, the researcher would be required to continue monitoring the conditions of the market to actually prove his or her hypothesis.   The fact that the housing market actually experiences a boom does not necessarily imply that the boom will create economic growth or not turn into a slump soon enough, thereby invalidating all growth processes expected for the boom period, and which had supported the boom theory of the researcher. Bearing in mind the various stages of scientific analysis, I disagree that the drug dealers still live with their moms – as Levitt proves in chapter 3 – because they have incentives other than making profits that compel them to work at lower than the minimum wage for such a high risk job.   I believe that the main motivation for countless people who are willing to do such risky jobs is high profits for sure.   Considering the costs and benefits, as Levitt demonstrated in chapter 3; the marginal benefits for the foot soldiers to sell drugs are much smaller than the marginal costs, if indeed the income of drug dealers is very low while drug dealing is a very high risk job.   There seems to be no incentive for the foot soldiers to perform a high risk job for low incomes.   Only those who are drug addicts already may accept the job because of their poor mental condition as well as the fact that they need the drugs to keeping entering their bodily systems.   Moreov er, the marginal costs continue to increase as the longer they sell drugs on the street the more chances there are for them to get caught or shot.   Marginal benefits, on the other hand, continue to decrease.   Seeing that the marginal benefits will never equal the marginal costs, there is definitely no efficiency in drug dealing.   If Levitt is correct to state that the drug dealers are working at lower than minimum wage, then no one would want to sell drugs as human beings are rational but selfish, and risk- and effort- averse. It is important to consider the four meaningful factors that determine a wage – which Levitt uses to explain why the typical prostitute earns more than the typical architect.   The factors help explain why the typical drug dealer actually earns a high wage.   Just as little girls do not typically grow up dreaming of becoming prostitutes, individuals cannot be expected to grow up dreaming of becoming drug dealers and ending up being imprisoned or killed.   The skills of the drug dealers, while not necessarily specialized, are practiced in a very specialized context.   The job is unpleasant because of the high chances faced by the drug dealers of being imprisoned and getting killed.   Yet, the demand for service that the job fulfills is extremely large.   The office of national drug control policy has estimated that Americans spent $140 billion on illegal drugs in 1990 and about 1 in 15 Americans aged 12 and over currently uses drugs.   The estimates for worldwide drug use may also be considered to get a clearer picture of the demand situation for drugs.   After all, drug supply around the world is part of a global business with innumerable links. The incentives for the street drug dealers that Levitt demonstrated in chapter 3 do not apply to the majority of drug dealers in the United States.   The examples of drug dealers that he used are only the poor black people who have grown up in a housing project on Chicago’s south side.   To them the path to a decent legitimate job was practically invisible and crack dealing was a glamour profession.   If the same sampling bias is used on the prostitutes, they would be impossibly earning more than the architect.   Just as the typical prostitute earns more than the typical architect, the typical drug dealer earns more than most people sitting behind office desks.   Many teenage drug dealers have managed to earn well enough to be able to afford private art schools and nice cars.   Furthermore, many of the drug dealers are able to lead lives of luxury.   It is the type of neighborhood that they sell drugs in that makes the biggest difference in their lifestyles.   In other words, it is the business environment and the income of the consumers in their immediate market that actually determines whether drug dealers would live with their moms or in their personal mansions.   After all, the drug dealer who sells drugs to the rock stars and movie stars in Hollywood is not expected to live with his or her mom, while the drug dealer who deals in the tenderloin in San Francisco probably would. Levitt also compared the crack dealing business with the entertainment business in the sense that a lot of people are competing for a very few prizes in these businesses.   Criminals, like everyone else, would like to believe that maybe one day they would become the leaders of the crack cocaine dealing business and afford to lead lives of luxury.   This coincides with my belief that the monetary factor is what actually drives the drug dealers.   Levitt explained that crack dealing is similar to the glamour professions, whether they concern the movies or sports, although there is a different dynamic at play.   Swarms of bright young people throw themselves at grunt jobs that pay poorly and demand unstinting devotion as they all have to play the same game viewed as a tournament.   In the entertainment industry, like all other highly competitive industries, the workers at the bottom are poorly paid.   At the same time, however, people are usually willing to work long and har d so that they can move up and eventually get paid more.   The high-school quarterback, infamous actors and actresses, as well as musicians and designers may earn lower than the minimum wage before hitting big.   Thus, before the drug dealer or the entertainer is made famous, he or she must be poorly paid. Drug dealing is the opposite of many competitive industries in a variety of ways, despite the fact that it shares important business principles with them, e.g. the quest to maximize profits.   There is no dearth of jobs in the drug business, as the demand is extremely huge.   Additionally, there is very high risk attached to the job, while the job itself does not make the drug dealers proud.   Needless to say, people are not expected to be attracted to drug dealing as a job unless they are drug addicts who do not mind the risks.   Hence, it is important to consider the labor supply of the market for drugs.   As the demand is extremely large and inelastic because cocaine and crack are very addictive, the prices of the drugs are higher then the equilibrium price.   Levitt mentioned that cocaine is, indeed, very expensive.   It is but commonsense that the selling of cocaine must yield high profits.   Indeed, this is the very incentive for which the labor supply increases . This is also the strong incentive that causes the drug business to expand.   After all, the drug business is virtually uncontrollable and constantly expanding throughout the world.   Oscar Danilo Blandon helped to establish a link between Colombian cocaine cartels and inner-city crack merchants.   According to his explanation, the supply curve shifted outwards as the price of relevant resources decreased because there was no middle man.   Thus, the invention of crack as the invention of a new technology resulted in increased supply.   The drug dealers around the globe are making bigger profits than the technology experts perhaps.   People continue to be more driven to sell drugs. Drugs dealers do, indeed, make a lot of money. They still live with their moms because the nature of this business involves high risks.   Thus, it is very unstable.   Because of the high chances of getting caught or shot for drug dealing, many dealers quit before they have made enough money to support themselves for the rest of their lives.   Even so, there are drug dealers in America who make a huge amount of money selling to the rich and famous.   Indeed, the income of a drug dealer is dependent on the socioeconomic status of his or her customers.   The business is unregulated in most parts of the world, so therefore its prices are unregulated.   Moreover, the expanding drug business around the world proves that drug dealing must be highly profitable for numberless people.   The drug business must also have its role to play in global economic growth.   If it is underground, it does not necessarily mean that the business does not help the economy grow.   Thus, conv entional wisdom must always be questioned for the researchers to find the best possible answers to our burning questions.   Settling for less, that is, inappropriate albeit simplistic answers, is not sufficient for the level of intelligence that is conducive to high economic growth.

Mercury Essays - Chemistry, Matter, Mercury Compounds, Mercury

Mercury Essays - Chemistry, Matter, Mercury Compounds, Mercury Mercury Mercurys symbol is Hg, its atomic number is 80, its atomic mass is 200.59, its in group 12 and in period 6, and it also has two valence electrons. Its standard state is liquid at 298K and it is the heaviest known elemental liquid. It has a silvery white color. It is named after the planet Mercury the origin of the symbol Hg is the Latin word hydrargyrum meaning liquid silver. Mercury was known to ancient Chinese and Hindus before 2000 B.C. and was found in tubes in Egyptian tombs dated from 1500 B.C. Mercury is the only metal liquid at ordinary temperatures. Mercury is sometimes called quicksilver. It sometimes occurs free in nature and is found mainly in cinnabar ore, which is HgS. Cinnabar ore is found in Spain and Italy. Mercury is a heavy, silvery-white metal, which forms alloys easily with many metals like gold, silver, and tin. These alloys are called amalgams. Its way of amalgamating with gold is made use of the recovery of gold from its ores. Mercury is a bad conductor of heat and an okay conductor of electricity. The most important salts are mercuric chloride HgC12 that is a corrosive and violent poison. Mercurous chloride Hg2Cl2, which used to be used in medicine. Mercury fulminate Hg(ONC)2 used as a detonator in explosives and mercuric sulfide HgS used as a high-grade paint pigment. Organic mercury compounds are important and dangerous. Methyl mercury is a lethal pollutant found in rivers and lakes. Mercury is a virulent poison and is readily absorbed through the respiratory tract, the gastrointestinal tract, or through unbroken skin. It acts as a cumulative poison since there are few pathways available to the body for its excretion. Since mercury is a very readily vaporizable element at a relatively low temperature, dangerous levels are readily attained in air. Air saturated with mercury vapor at 20C contains a concentration that exceeds the toxic limit many times. The danger increases at higher temperatures. It is therefore important that mercury be handled with care. Containers of mercury should be securely covered and spillage should be avoided. Mercury should only be handled under a well-ventilated area. Mercury is well known because of its use in many thermometers. It was common to demonstrate the formation of mercury in the laboratory by heating mercury s ulfide. This method forms the basis of commercial extraction to get mercury. The prepared cinnabar ore is heated in a current of air and the mercury vapor condensed. Bibliography 1.

cannabis and psychosis

cannabis and psychosis The association between substance misuse (cannabis however they impose a considerable personal and public health burden (Degenhardt Regier et al. 1990). This Comorbidity as a result largely enhances cost associated with treatment, predominantly in relation to hospital and other institutional services. The majority of the evidence regarding prevalence of substance use and mental illness comes from the United States, though European standpoint on prevalence is rapidly rising. One of the first and most famous US study is The Epidemiological Catchment Area study conducted by Regier et al. 1990 across 5 US sites, which involved over 20.000 participants. This study tried to measure how common dual diagnosis was and stated that 47% of the participants they surveyed with schizophrenia or schizophreniform disorder also met the criteria for substance use disorder/dependence at some point in their life. Furthermore, the likelihood of having substance use disorder amongst patients with psycho tic illness was notably higher compared to those in the general population without a psychotic illness (Kessler et al. 1994; Regier et al. 1990). In sharp contrast, studies that have been conducted in the UK have reported more moderate rates of substance misuse amongst those with psychotic disorders. For instance, Cantwell in 2003 undertook a study with 316 patients with schizophrenia and only 7% had stated that they had a problem with substance misuse in the previous year, and 21% had reported problematic use some time before that (Cantwell, 2003). Similarly, Wright and Colleagues identified patients with psychotic illnesses who had been in contact with services in the London Borough of Croydon and reported that prevalence rates of dual diagnosis were 33% for the use of any substance and lifetime history of any illicit drug use was 35% of the sample (Wright et al. 2000). Cannabis is the most frequently used substance in patients with psychotic disorder (Van Mastrigt et al. 2004; Ba rnett et al. 2007) and the literature indicates fairly consistently the association between regular uses of cannabis and developing first-onset psychosis[1] (Grech et al. 2005). However, the causes for the links are still hotly debated. Nevertheless, cannabis has damaging effects on the course of the illness on top of being an economic burden on health services (Atakan, 2009). More specifically, estimates of frequency of cannabis abuse amongst patients with first-episode psychosis is said to range from 20% to 70% (Miles et al. 2003; Isaac et al. 2005). A systematic review of 53 treatment samples and 5 epidemiological studies looking at the prevalence of cannabis use and misuse among those with psychotic illnesses stated lifetime use in 42% and lifetime misuse in 22.5% of the sample while current use was 23% and misuse 11.3% (Green et al. 2005). Furthermore, epidemiological studies also have shown that cannabis is the most frequently abused substance amongst younger people (Van Mastr igt, 2004; Addington Wade et al. 2007) with lower educational background (Mueser et al. 1990) and it is more common in men than in women amongst first-episode psychosis patients (Barnett et al. 2007; Addington Barnes et al. 2006). Inevitably, cannabis abuses among youth experiencing a first-episode psychosis results in negative consequences for prognosis and relapse and therefore complicate treatment and impair recovery (Archie et al. 2009). It is constantly reported in the literature that patients with first-episode psychosis who abuse cannabis had considerably more hospital admissions rates as well as more psychotic symptoms compared to first episode psychosis patients who do not abuse cannabis (Wade et al. 2006; Negrete et al. 1986; Turkington et al. 2009)

Care of the patient having Cytotoxic Chemotherapy (GM50Z8) Essay

Care of the patient having Cytotoxic Chemotherapy (GM50Z8) - Essay Example To think that patients are already in a very critical condition, they still have to deal with problems of comprehension. Many are confused especially on the technicality of their disease or treatment. Not everyone can easily understand a doctor’s intellectual explanation. The emergent proliferation of Patient Information Leaflets (PILs) has become an immediate solution to this problem. Leaflets are free consultation take-outs from a trusted doctor; it is an instant consultation. Whenever you forget some details about a disease or a treatment, you can always refer back to your leaflet. The leaflet must contain answers to most frequently asked questions. It can save time and consultation fees. However, the issue at hand is, are they effective? Do patients/relatives/supporters do actually read them. The challenge is to make them read and understand leaflets. Specifically, the main question of this paper is, is the leaflet on Cytotoxic Chemotherapy a helpful guide and preparation for cancer patients and a good source of information for relatives and supporters of these patients? The following paragraphs will be a critical review of â€Å"A Patient’s Guide to Chemotherapy†. The leaflet is aimed to guide adult cancer patients undergoing chemotherapy, their families and supporters as evidently mentioned in the first section of the leaflet. Definitely, they are the target audience of the leaflet and not the patients suffering with any other disease or illness. It would be useless to distribute leaflets to those who will not use them. It is very important that these leaflets must go to the hands of the target audience. Leaflets as mentioned earlier are answers to most frequently asked questions, and the leaflet on chemotherapy should answer a cancer patient’s questions on his or her own chemotherapy treatment. It should clarify any gray areas on the said topic. After reading it, the patient or the patient’s supporter must greatly understand the

The first change took place in the form of shift towards diversifying mergers and move away from the traditional combined competing or vertically relating the companies (â€Å"in the United States; less in other industrial countries†). The second change occurred in the form of development of â€Å"event studies† (â€Å"a method of inferring the profitability of mergers ex ante from changes in stock-market values at the time when the transaction is announced†) (Caves, 1987, p.150). Hence, from the above discussion it is evident that the concept of merger and acquisition underwent a drastic shift since these two upheavals took place. Earlier studies have shown that merger and acquisition have been responsible for incr easing the social welfare, augmenting the value of the assets of the firms involved into merger or acquisition (Agrawal, Jaffe and Mandelker, 1992; Augustine, 1995). The notion of merger coincided with history long back during the year 1708 (Caves, 1989; Franks, Harris and Titman, 1991; Franks and Harris, 1989). For example, during this period the East India Company merged with one of its erstwhile competitors for the principal purpose of restoring its monopoly in the Indian trade environment. In the similar way, the year 1784 experienced the two Italian giant banks Monte Pio and Monte dei Paschi united to form

Centuries and Primary Crop Uzbekistan Essay Example for Free

Centuries and Primary Crop Uzbekistan Essay Population:With 26,851,195 (in 2005) people, Uzbekistan has the largest population of the former Soviet republics in Central Asia, and the third-largest population of any former Soviet republic. Population density is 60 people per sq km. The population was 37 per cent urban in 2003 and life expectancy was 61 years for men and 68 years for women. The countrys population growth rate was about 1.7 per cent per year in 2005. Health Problems:In 1999 there were 354 people to each doctor, and in 2005 the infant mortality rate was 71 deaths per 1,000 live births. Expenditure on health in 2002 was 3 per cent of GDP. Economy:The GDP per capita of Uzbekistan is a low $2000 US, with 33% of the population that lives below the poverty line. This even though it exports $5 billion f.o.b. Tertiary, Primary, secondary industries:Agriculture contributed about 35 per cent of GDP and accounts for 34 per cent of total employment. Cotton is the primary crop†¦ Uzbekistan is a leading producer of seed cotton. The republic is also the largest producer of silk and karakul pelts in the former USSR. Other important crops include wheat, rice, barley, and a wide variety of fruits and vegetables. Since most of Uzbekistans agriculture is devoted to cotton-growing, however, the republic has become very dependent on outside sources of food. It must import about two thirds of the grain, one third of the meat, one quarter of the milk, and half of the potatoes consumed in the republic. Legislation was passed in 1992 to permit private enterprise in agriculture and by 1996 more than 90 per cent of state farms had been transferred to the private sector, which accounted for more than 98 per cent of agricultural production in the same year. Civil Unrest:Uzbekistans rate of violent crime, including against foreigners, has increased in recent years. In urban areas, travelers are urged to take the same precautions against crime that they would take in a large American city. In Uzbekistan, many riots arise due to mainly political issues, sometimes causing a massive civil war. One major example of this is the Andijan massacre. When Uzbek Interior Ministry and National Security Service troops fired into a crowd of protesters in Andijan, Uzbekistan on 13 May 2005. Estimates of those killed range from between 187 (the official count of the government) and 5,000 people, with most outside reports estimating several hundred dead. The exact number of victims is still uncertain. The bodies of many of those who died were hidden in mass graves after the massacre. Colonial History:Although Uzbeks have lived in the area of present-day Uzbekistan for centuries, a national Uzbek political entity was formed for the first time in the 1920s. The region of present-day Uzbekistan was the site of the ancient Persian province of Sogdiana and was conquered by the Macedonian leader Alexander the Great in the 4th century BC and by the Arabs in the 8th century AD. It was incorporated in the Mongol empire of Genghis Khan in the 13th century and the Mongol empire of Tamerlane in the 14th century. The Uzbek khanates of Bukhara (also spelled Bukhoro) and Khiva emerged in the 16th century, and the Kokand khanate was formed in the 18th century. Russian control was extended over the region between 1865 and 1873, with Khiva and Bukhara remaining vassal states of Russia. Natural Resources:Uzbekistan is rich in mineral resources that include natural gas, petroleum, coal, gold, silver, uranium, copper, lead, zinc, molybdenum, and tungsten. Irrigation systems fed by the two major river systems sustain agricultural production around the fertile river valleys. Electrical production is principally by thermal plants but there are some hydroelectric sources. Political Stability:Chief of state: President Islom KARIMOV (since 24 March 1990, when he was elected president by the then Supreme Soviet)Head of government: Prime Minister Shavkat MIRZIYAYEV (since 11 December 2003)Cabinet: Cabinet of Ministers appointed by the president with approval of the Supreme AssemblyElections: president elected by popular vote for a seven-year term. The election results: Islom KARIMOV reelected, % of vote = Islom KARIMOV 91.9%, and Abdulkhafiz JALALOV 4.2%-Last election was last held on the 9th January 2000 (next to be held in 2007). -Prime minister, ministers, and deputy ministers are appointed by the president.

The novel Lord of the Flies

Why is evil attractive? Lord of the Flies by William Golding dramatized the primordial evil that is in man’s subconscious. Although normally,   civilized human beings consider evil undesirable and therefore to be avoided, the fact is, many are drawn into it. Evil holds some kind of a seductive quality that less morally discerning people find hard to resist. Setting evil intentions in context In this novel, Golding gave life to various characters that represent the two basic types of people in this world, the good and the bad. Ralph, Piggy, and Simon were the good ones, while Jack and Roger were the evil ones.   Stranded in a deserted tropical island, Ralph and Piggy wanted to establish rules,   build shelters, secure clean water and food. But the tasks to achieve these were boring and   most of the boys wanted just to play and hunt. Jack who was the leader of the hunting party, would soon emerge as the more attractive and powerful leader. Playing and hunting are not evil   in themselves but in the novel, these were seeds of evil that would soon grow into disturbing magnitude. The boys in Jack’s group enjoyed hunting and killing the animals and eventually became obsessed with hunting and killing Ralph. This paper analyzes how evil holds some kind of attraction and why people are drawn into it. There are at least three hypotheses–   (1) Evil is attractive because it gives a pleasurable experience; (2) Evil is attractive because it satisfies bloodlust, considering the belief that there is a murderous inclination in every man; and (3) Evil is attractive because of the opportunity it provides to play God, to be in control, to be powerful. With Golding’s work as point of reference, this paper illustrates how the conflict between good and evil continues to occur in various ways, in different people.   The film by Adrian Lyne,   Unfaithful that starred Diane Lane and Richard Gere is used here as one example. In this film, all the mentioned premises above were   portrayed. Like the English boys in the novel,   Connie and Edward, the couple in the said film were decent, intelligent, and admirable. However, when thrown in a critical situation that tested their character, the evil in them triumphed over the good.   The basic assumption of course is that man is dual, both good and evil. Always man struggles with this internal conflict. Lust for flesh, blood and power In the novel, â€Å"†¦ Jack found the throat and the hot blood sprouted over his hands. The sow collapsed under them and they were heavy and fulfilled upon her.† (Golding) The imagery evoked by this description is   sexual.   A primordial bloodlust was satisfied. In the film, Unfaithful,   Connie was drawn into an affair with Paul because of the sheer pleasure of the experience, despite the fact that she had a good home and a fulfilling marriage. The film seemed to suggest that her motivation was irrational. She had an affair because a strong wind was blowing. She slipped on the road and cut her knee. The irresistible lover-to-be was passing by and offered help, invited her to his apartment to dressed her wound. Later she called to thank him. He invited her for coffee and she accepted.   From there began a series of trysts. Connie’s hubris ( Greek for sin of pride) was assuming she was in control, that she can have an affair and then forget about it and go on with her life. Unfortunately, she kept coming back to his flat and   began to neglect her duties. When Edward, her husband found out,   he also assumed he was in control and attempted to confront Paul, the lover in a civilized way.   However, when Edward saw their wedding anniversary gift in the lover’s bedroom, he lost control and   bash Paul’s head, thus killing him. Connie and Edward eventually became partners in crime as they worked to dispose Paul’s corpse and lied to the police. Connie chose not to channel her passion into something creative. She yielded to her sexual energy instead.. Her pride and   confidence, her sense of adventure overpowered her. She probably knew what she was doing was wrong but went ahead because she had not been very spiritually discerning lately.   She was young, attractive, comfortable, loved, secure. It never occurred to her to pray to be a faithful wife. She assumed she can get away with infidelity, never thought she was putting   her marriage and loved ones at great risk when she chose to give in to lust for flesh. Edward was good and tried to make things right, perhaps persuade the lover to stop seeing his wife. But in a sudden burst of insane rage triggered by the sight of   their wedding anniversary gift that found its way into Paul’s room,   Edward killed the latter..   Suddenly his lust for blood craved to be satisfied. In the end, both wife and husband wanted to assume ultimate control over the evil they have done. Instead of trying to rectify their sins,   regain their worth as human beings and pay for their crime, Connie and Edward chose instead to cover up their evil deed. They have totally given in to the machination of the devil. Man cannot just kill the beast Man, in his foolish naivete, continue to believe the devil’s lies about happiness,   knowledge, and power. In the song, â€Å"Hotel California† by Eagles, a few lines mentioned â€Å"the beast.† And in the master’s chamber They gathered for the feast But with their steely knives They just can’t kill the beast. Man can not just kill the beast in him, and so he has to be alert and spiritually discerning. The evil in man’s subconscious may surface when he least expect it and cause him   to commit a sin   that would destroy him and those around   him.   Always, the attraction of pleasure, bloodlust, and power will entice mankind to commit evil. The antidote is found in the New Testament,   in the book of Ephesians 6: 10-17, about putting on the   helmet of salvation and   the armor of God, consisting of truth as belt, justice as breastplate,   zeal to propagate peace as footgear, faith as shield,   and the word of God as sword of the spirit.

Enrollment System Essay

Enrollment is the focus of the Compfuturist that would lessen the institution’s difficulties in their Information System processing, solve data problems and an easier access of the establishment’s information. Every enrollment, 80-100 enrollees come for the dates of admission having a maximum of 30 for each level, in present time classrooms are consist of 15 students. An easier recording of files and a database to save documents will lessen the space being occupied by the records of the students. A faster transaction, easier ways for inputting datum and a convenient ways for saving files are offered for the use of the establishment by the enrolment system. The commonly used advertisements of schools are brochures, leaflets, banners and calling cards; the group also offers a website that will be used to improve its approach to people. The website would be a help for parents about the notice or updates of events and gatherings, it would also be a way to know the history of the institution and the contact details of the establishment. The incomplete requirements are the main problems during the enrollment, one of which is the student information, some of the information needed is not filled up and some are important to the school records. In the Pre-School it is required for them to have the copy of their birth certificate, two (2) copies of a 2Ãâ€"2 photo and an interview with the Pastor or Principal. For the grade-schoolers a photocopy of the birth certificate, the form 138, a certificate of Good Moral Character for transferee and an interview with the Pastor or Principal. Due to the uninformed people about the requirements needed some are not brought and are filed to be uncompleted forms. Each student has a folder that contains his or her information about the birth certificates, previous records from the earlier institution he or she attended, the quality point average for each year and also the permits signed by the parents. Enrollment takes time and effort from the parents, students and also from the teachers; every step of an enrolment, a teacher is assigned to instruct a parent or guardian what to do and where to go next. The slow process of enrolment makes the parents furious and makes the job even harder for the teachers for them to rush, that sometimes some records are not being filed or are not properly assigned. Missing documents are also a cause of problem for the institution, it might be placed to another folder or the parent forgot about it. A school’s updates about events and gatherings are the problems for teachers and parents. Students forget to tell their guardians or forgot to give the letter accustomed by their advisers. The result of the forgotten events cause students not to wear the proper attire, parents does not attend meetings and gatherings, students are thought to be absent for specific happenings and also parents become indignant about the unknown proceedings. Project Framework The Compfuturist Group offers the instituion. a system and a website that would shoulder the difficulties of the institution. The school appoints teachers to handle the student information during the enrollment. Software that is specially made only for Mabalacat Christian Academy and a website that would help the advertisement of the school increase. The system can only be open by an authorized member or the principal of the institution. Passwords and accounts would be made for the privacy policy made by the institution to safeguard each student’s information and background. The Student Information Sheet or Form would consist of the basic details about his or her family, previous schools the child attended, number of siblings, if there were awards he or she got from previous levels, address, contact number of the parent or guardian and more information that are to be filled by the guardian. An option will be given to the parent or guardian if the transaction of payment would be a full payment or a partial payment every quarter and a choice to have it paid through cash or cheque. A database would be given with a maximum capacity of 300 and a number of 50 students per level. A website would be provided for the institution that would only be used for the use of the school’s advertisement, featuring the facilities of the establishment, faculty members, and history of the school and updates of happenings. The page would be the source of parents to be updated to the school’s events; when, where and what to wear. Specific events require students to wear a garment requested by the institution for uniformity. The page can also be a source and guide for parents and guardians to know the details and history about the school. Contact details would be posted and an added detail of the page is that if parents are working abroad they could send the uncompleted requirement to the email of the school with attachment of the requirements. The Facebook page of the institution is also posted to the website and could be directed to the page created by the faculty members of the school. Statement of Objective Website and Enrollment System is a program extended to Mabalacat Christian Academy, a program that would make the transactions of requirements and documents, and also help about the school’s reputation about the improvement of its ways. It could solve the problems of the school since it started; the system only solves the problem of the school paperworks and will lessen the space of the documented files. The System is a program that would make the process of filing student information faster and easier to save for the school. The enrollment system’s purpose is to give a database for the files of students, a maximum of 300 files for the whole institution and an easier way of searching student files. A transaction that would make the access of information system easier for the authorized people, a faster accessibility in information provided and an improved process; the admission and acceptance of enrolees would be faster for the completion of forms would not be difficult for teachers to save and keep. The Website will inform the parents of the situations, cancellation of classes, school events, PTA meeting schedules, examination dates and payment dues. An account will be given to the principal or school head to access the student accounts and website if changes are to be made, the account given to the principal can also be used to check the number of students enrolled and to what level they are assigned to Importance of the Study The Compfuturist created a system only from Pre-School to Elementary levels and for an institution with one section per level, the system subjects only to the enrollment, saving and filing of documents and the postage of contact details of the institution. The use of the program is to lessen the burden of alphabetizing envelopes for each level and student, it also makes the search of a student file faster compared to the manual based of searching through metal drawers. A database that would show and save documents for specific purposes and privacy of files will be kept and safe from others to see. Only the Principal and the appointed faculty or member of the institution could access the information system of the database provided by the system. The institution would benefit from the free system that could be used for years and less updates of program would be given for the system is only for the use of Mabalacat Christian Academy. Parents and students would also benefit from it because information given from the old students will not be inputted again but be moved to the folder that consists of the level he or she is. The editing and adding of details is convenient even to those people who are not good in using computers. Less stressing and easier to use, is the way that the program or system offers to its benefactors. Radio buttons, scroll bars and more features of the program and website would be given to lessen the difficulty that some encounters in web pages and softwares. A free ten (10) months of maintenance is given for the institution and would make things better compared to the existing manual system.

Modern Estates Church, Nobility Peasantry

Modern Estates Church, Nobility Peasantry The three chronological estates (Church, Nobility, Peasantry) can be used analogically in the current western society. This is a critical provision when considered decisively. The first modern estate relevant in this context is the Executive Branch of most governments in the contemporary western society.Advertising We will write a custom essay sample on Modern Estates: Church, Nobility Peasantry specifically for you for only $16.05 $11/page Learn More In the medieval society (analogically), the church (clergy) was given power to make decisions, give credible directions, and provide viable living wits. As the top (powerful) arm of the society, it manipulated and molded the concerned society to favor its religious, governance, and societal interests. Currently, this is relevant in the executive branch of most governments in the contemporary western society. The current governments dictate how people should live, interact, eat, drive, solve disputes, own prop erties, and relate in the society among other provisions. This is a critical provision in the context of governance as indicated earlier. Executive arm of government has the final say in the contemporary western society. Rules (modern laws) have been set to govern most institutions and other considerable provisions relevant in this context. Considerably, this estate (in the modern setting) would form the governmental entity meant to provide operational directions in the contemporary western society. It is important to understand this provision in various analogical contexts. The description provided indicates how this group (estate) should appear in order to conform to the provisions of the first estate. The second analogical group in the contemporary western society is the legislative arm of government. Currently, the society elects politicians (legislators) and other officials to fight for their demands and enact fair distribution of national resources. This is meant to establish and ratify equity.Advertising Looking for essay on political culture? Let's see if we can help you!

Similar to the second estate in the medieval society (Nobility), the contemporary western society possesses the legislative arm of government as an equivalent. It is critical to understand this provision as indicated earlier. While considering how this estate would be and describing its appearance, the legislative arm of government possesses (analogically) numerous provisions. Firstly, they possess considerable powers over their respective states and subjects. Concurrently, they should continuously fight for their opinions and propose viable governmental and societal provisions for common citizens. Analogically, this group enjoys special tre atment in the society based on profiles and roles subjected to them. This is evident in the realms of remuneration, security, healthcare, and retirement benefits. The third group (analogical to the ‘Peasantry estate’ in the medieval society) is the working class (individuals who work tirelessly to support the nation). Through its efforts, the working class ensures that the entire society is fed appropriately. They pay taxes to support the first two groups mentioned earlier. Analogically, this group refers to the entire public, which constitutes the fast food workers, office staffs, and other employees in diverse sectors. In the medieval society, the ‘Peasantry’ estate referred to the low class individuals who toiled to support the rest of the society. This provision is relevant in the contemporary western society.Advertising We will write a custom essay sample on Modern Estates: Church, Nobility Peasantry specifically for you for only $16.05 $11/ page Learn More Nonetheless, it is crucial to understand the entire survival and categorical aspects of the modern world. Precisely, is suggestible that the contemporary western society can be put into three groups namely the executive arm of government, the legislature, and the working class. Analogically, these groups are similar to the mentioned medieval divisions.

Health Education Plan Assignment Example | Topics and Well Written Essays - 1000 words

Health Education Plan - Assignment Example Particularly, in Los Angeles, more than one in five students in Grades 5th, 7th and 9th were found to be obese (ibid.). This truth puts the youth at risk of obesity. This paper addresses the present problem by proposing a community health education plan for parents of at-risk and obese youth in Los Angeles. First, the paper tackles the present problem based on recent statistics and community health analysis. Second, it proposes a comprehensive education plan aimed at parents to guide them in child weight management. Third, it suggests relevant research to control the obesity situation in the Los Angeles community. The health education program shall run for six months, and a monthly assessment should be done to note down the improvements not only in the weight of the population but likewise in their eating habits and view of nutrition. The program shall include nutritional information, cooking sessions, exercise drills, activity planning, school and house-to-house visits, and follow u p sessions. The objectives of the program are as follows: To provide information on obesity, its causes and effects, and other related information To improve the eating and cooking habits of families by conducting cooking sessions, information campaign, and school/home visits To increase the physical activity and exercise habits of the community by conducting physical exercise, teaching them how to plan and monitor their children’s physical activities, and providing means for physical activity among the youth To inculcate the value of health and good nutrition among the youth by holding poster-making contests, rhythmic gymnastics, and other forms of exercise. The participants shall be composed of parents and children. Mothers and fathers are both welcome to attend the activities, which shall be held for two hours every Saturday morning and may extend in the afternoon, to give way for other activities such as contests, exercise, and other physical activities for children. The success of implementing a health education program depends on proper planning and assessment. Thus, in order to achieve success, an analysis of the target population and Los Angeles county based on Windshield Survey must be conducted first. A Windshield Survey of Los Angeles primarily shows that it is a well-populated county. It is home to different ethnicities including African-Americans, Latinos, Whites, and Asians. In a research conducted in 2001 (cited in County of Los Angeles Department of Health and Services, 2003), it was found out that 55 percent of the county’s population is either overweight or obese, and many others are at risk for becoming overweight. Similarly, more than 15 percent of the adolescent population is overweight. African-Americans were found to have the highest incidence of obesity, and the problem is mostly related to low economic status (OHAE, 2007). Thus, the highest prevalence of obesity was noted among families with the lowest incomes. The relati on between poverty and obesity suggests the poor nutrition that families can afford. Families with low income usually feed their children with starch and carbohydrates, which is opposite the daily nutritional recommendation of five servings of fruits and vegetables and little fat. In this regard, it is important to include in the health education seminar the proper nutrition or recommended foods that parents should provide their children. This topic should be included in Day 1. The first session should

Fitting into society is not the easy way Essay Example | Topics and Well Written Essays - 750 words

Fitting into society is not the easy way - Essay Example At first, I found it difficult and impossible to adjust there as I was very weak in English. The condition of my written and spoken English may be compared to the situation of mother’s English in Amy Tan’s novel. As Amy describes it â€Å"I can think of no way to describe it other than â€Å"broken,† as if it were damaged and needed to be fixed, as if it lacked a certain wholeness and soundness† (62). I used to get irritated and annoyed while communicating to friends, teachers and other associates. The difference of language and accent made me feel low and helpless. My social circle was shortened to an extent that I felt isolated and lonely. This was the worst effect of moving from my native land to a new state. In China, we used to live and work in groups. Our decisions were based on the suggestions and perceptions of others. However, the American culture emphasizes on individuality and personal decision making. I found it really difficult to choose everything from the choice of my clothes to the academic field which I had to opt. In addition to this, the Chinese culture places more emphasis on the respect and acting upon on elders advices. I used to respect them and our communication ways with elders was more respectful and loving with children. However, in America, I experienced a major flaw in the society. Youngsters do not tend to give that level of respect and importance to elders which I was habitual of. I expected the same respect from the youngsters and loving attitude from the elders. However, this misconception ended as I experienced certain events and faced behaviors of American people in the park. I went out to the park with my college friends. It was a wonderful day. Everyone was enjoying and we were cracking jokes, listening to music and having fun. The first thing that irritated me was the song choice which differed greatly. But since most of the Americans

Fruit Fly Genetics lab report Example | Topics and Well Written Essays - 250 words

Fruit Fly Genetics - Lab Report Example About 10-14 days after the eggs are laid by the females, the adult flies emerge from their pupal cases. In this lab, we performed a dihybrid cross for dumpy wing/normal eye color and normal wing/sepia eye color. In a dihybrid cross, two different mutants are crossed to each other and a sibling cross is performed with the progeny from the F1 generation. The dihybrid cross is performed to determine if two genes assort independently or if they are genetically linked. If the two genes assort independently, the expected phenotypic ratio is 9:3:3:1. If the two genes are on the same chromosome and linked, there will be fewer recombinants that have a phenotype different from either parent in the P generation. Since dumpy and sepia are both recessive traits, the F1 generation will be phenotypically wild-type. The dependent variable is the number of each class of flies in the F2 generation (wild-type, dumpy, sepia, and dumpy/sepia). The controlled variables are the genotypes of the P1 and F1 generations. The P1 generation will be either red eyed, dumpy or sepia, normal wing. The F1 generation will all be heterozygous for both mutations. This is verified by making sure that the F1 flies used for the cross all have the wild-type phenotype for both wings and eyes. Flies were sorted by genital morphology and the presence/absence of sex combs under a dissecting microscope following anesthetization with FlyNap. Flies were cultured and allowed to develop in vials with water added to dry media and supplemental yeast. Progeny from each cross were allowed to develop in the vials and emerging adults were collected. The P and F1 generations were sorted and 10 males and 10 females were placed in new culture vials with food to set up both crosses. The F2 progeny were counted by phenotype and the data was recorded. The phenotypes were scored as either dumpy or normal wings and red or sepia eyes. ÃŽ §2 statistical analysis

Social class Essay Example | Topics and Well Written Essays - 2000 words

Social class - Essay Example In order to understand these factors, it is imperative to begin by explaining the meaning of buyer or consumer behaviour. The main body of the paper will evaluate the role played by different factors in light of neuroscience. â€Å"Consumer behaviour comprises the behaviour patterns of decision units (individuals as well as families) which precede, determine and follow on the decision making process for the acquisition of need satisfying products, ideas and services,† (Strydom, 2004, p.2). On the other hand, McCarty & Perreault (1996) posit to the effect that the needs of the consumers, their motives, perceptions, attitudes, learning abilities and their personality have a bearing on their consumption patterns and buyer behaviour towards certain market offerings. Of notable concern is the fact that the consumers do not live in isolation from others and their buying behaviour is also impacted by factors such as culture and other social factors obtaining in their respective socia l environments. Aspects such as cultural and reference groups, family and the social class system impact on the buying behaviour of different people and these should be taken into consideration by the marketers. The study of buyer behaviour mainly draws from psychology with additional inputs mainly from sociology as well as Economics (Lancaster &Reynolds, 1999). Sociologically, the behaviour of people is shaped by factors such as friendship, love, status as well as self esteem among other factors while psychological factors are mainly concerned with attitude and perception developed by people towards something. There are several reasons why an individual may buy a particular product but the major one is to satisfy different needs as postulated by Maslow’s hierarchy of needs (McCarthy & Perreault, 1996). Before making a decision to buy a certain product, a need must first arise and this need has to be satisfied. This in turn compels the individual to make a decision towards pu rchasing a product that can satisfy the need. According to Lancaster &Reynolds (1999), the buying behaviour of an individual is determined by factors such as perception, needs, motives as well as attitudes which are either directly or indirectly influenced by the individual’s ability to learn. A person first acquires buying and consumption knowledge about a particular product and this stage is mainly referred to as cognition. This process can be attributed to the cognitive theory which posits to the effect that that a considerable amount of learning takes place here due to the fact that the customer comes into contact with a certain product and develops a keen interest in it. Before making a decision to purchase that particular product, the customer first learns about the product to gain more knowledge and insight about it. According to this theory of consumer behaviour, the customer is viewed as a problem solver who first seeks knowledge in order to solve a problem through i nformation gathering. Mental processing is involved where the mind is manipulated in order to arrive at the desired goal. The power of reasoning is central in this process and it can be noted that as human beings we subconsciously learn about something through coming into contact with it. For instance, the buyers can learn about a product like toothpaste particularly Colgate through coming into contact with it since there are different brands. Knowledge about a product is created during the early

Effect of Agency on Gambling Behaviour in Schizophrenia

Effect of Agency on Gambling Behaviour in Schizophrenia The Effect of Agency on Gambling Behaviour in Paranoid Schizophrenia Introduction Our sense of agency is a form of self-consciousness which allows us to distinguish between ourselves and other individuals; it makes us aware of which thoughts and actions are our own (Haggard Chambon; 2012). This construct can be measured through the use of the intentional binding task (Moore Obhi; 2012). When an individual preforms an action that is then followed by an effect such as an auditory tone, there is a perceived reduction in the length of the interval between the action and the effect. Since this only occurs for actions that are intentional, this phenomena is called intentional binding and has been suggested as a reliable measure of agency (Haggard, Clark Kalogeras; 2002). A disturbed sense of agency is symptomatic of schizophrenia, a long term psychotic disorder marked by severely impaired thinking and abnormal behaviour, including delusions and hallucinations (Andreasen Olsen; 1982). Sufferers of the disorder may either feel that external forces are controlling their actions or thoughts, or they may feel in control of events that in fact are not caused by their actions. Martin (2013) called this experiences of activity; patients form the grandiose delusion that they can control some external events by the sole means of their mind. The first intentional binding patient study (Haggard, Martin, Taylor-Clarke, Jeannerod, Franck, 2003) compared the magnitude of intentional binding in patients with schizophrenia to a healthy control group. They established that intentional binding was significantly more robust in patients compared to controls. Using the same task, a more recent study (Voss, Moore, Hauser, Gallinat, Heinz Haggard; 2010) found that the predictive component is either absent or faulty in schizophrenia, therefore a greater reliance on the external effect rather than the intended action leads to hyper-binding. The severity of positive symptoms, as in the paranoid schizophrenic subtype, was also found to correlate with impairments in action-effect predictions. Various studies have documented a high level of comorbid psychiatric disorders among individuals with gambling disorders, including Schizophrenia. Pathological gambling was first recognised by the APA as an impulse control disorder in 1980, and can be defined as the recurring behaviour of gambling on games of chance despite the resulting negative consequences, leading to the individual becoming incapable of controlling the time and money spent, even when losing. Research conducted by Desai Potenza (2009) investigated the co-occurrence between pathological gambling and schizophrenia. The researchers interviewed a sample of 337 patients diagnosed with schizophrenia. Using the DSM-4 criteria for pathological gambling, the researchers found that these patients may be at a particularly high risk; 19 percent were classified as either problem or pathological gamblers. Just under 10 percent met the diagnosis for pathological gambling, the most severe form of the disorder; recent studies hav e estimated the rate among the general population at less than one percent. Wegner and Wheatley (1999) suggested that the sense of agency also plays a role in phenomena such as superstition and gambling, in which individuals experience subjective control over uncontrollable entities; this is often know as illusion of control. Similar to delusions of activity in schizophrenics, various studies have shown that an irrational sense of personal control over the outcome, even in games of pure chance, is a possible factor in the maintenance of problem gambling. A study by Moore and Ohtsuka (1999) assessed the association between beliefs about illusion of control or internal locus of control and their relationship to gambling frequency in young people. The results indicated that irrational control beliefs were strongly associated with problem gambling; the illusion of internal control over gambling significantly predicted gambling frequency and problem gambling. Toneatto, Blitz-Miller, Calderwood, Dragonetti, Tsanos (1997) found that scoring highly on the South Oaks Gambling Screen (Lesieur Blume, 1987) was correlated considerably with exhibiting cognitive distortions during an interview, in which individuals expressed the belief that they are able to control the outcome of their gambling, along with an extravagant level of self-confidence. Heavy gamblers also made more active attempts to influence the outcome using gambling systems, rituals and superstitions. Sense of control over gambling appears to have cultural differences; Majamà ¤ki Pà ¶ysti (2012) found that Finnish gamblers stress their individual competence and will to take more risks than gamblers in France, even in games of chance, imagining a greater sense of control. Taken together, research suggests that Pathological Gamblers may experience a similar heightened sense of agency to Schizophrenics, in that they exhibit the illusionary idea that they are able to control outcomes which are not within their personal influence. Although the experience of agency between two disorders have not been directly compared, this could perhaps explain the high comorbidity between the two disorders. I therefore propose that a disturbed sense of agency will be present in both schizophrenics and pathological gamblers during a gambling task and may contribute to the development of gambling disorders. Methods In order to study the possible effect of agency on pathological gambling in schizophrenia, I intend to use as many participants as possible in order to obtain the largest, most generalizable sample; participants will be age and gender matched to eliminate extraneous variables. I will use the age range of 16-35, encompassing the peak ages of onset and acute psychosis whilst avoiding using minors for ethical reasons. I will be using a healthy control group, a group of pathological gamblers and a group of paranoid schizophrenics, as they present more positive symptoms than the other subtypes, which correlate with experience of activity delusions. In order to participate individuals must have a professional medical diagnosis for their disorder, as well as normal or corrected hearing and eyesight. Firstly, I would like to establish the level of individual sense of agency for each group during an intentional binding task. Following a voluntary or involuntary key press, participants will experience an interval followed by an auditory tone; they will then be asked to estimate the length of time between preforming the action and producing the effect in milliseconds. Research has shown that there is a perceived reduction in the length of the interval between the action and the effect where the participant believes that they produced the action voluntarily. Secondly, participants would complete a computer gambling task (Rachlin 1986) in order to simulate real life tendency to make a safer or riskier choice during a game of chance. This is a task in which they are asked to choose between two spinning wheels, where the pointer landing on a white coloured section would indicate a monetary win. On one wheel, a win is less likely but twice as substantial, on the second the win is less valuable but more consistent. In order to increase the ecological validity of the situation and hold the attention of the participant, they will have the opportunity to win the money collected during the task. This task will take place within a functional magnetic resonance imaging (fMRI) scanner. This machine uses the Blood-oxygen-level dependent contrast (Huettel, Song McCarthy (2009) in order to detect changes in cerebral blood flow during the task, indicating neural activity in different brain regions. Results and Implications My predicted results would be that based on prior research the schizophrenic group will experience substantially more hyperbinding on the intentional binding task than the healthy controls; however I also hope to see the same with the pathological gamblers. Amongst that group, those who experienced the strongest feeling of agency would take the most risks during the task. I would expect to see similar, and greater, patterns of activation in the areas associated with agency, specifically self-agency, during the task in the fMRI machine for the PG and Schizophrenic groups. This would include the TPJ Precuneus, which has been implicated in a large number of studies during tasks relating to agency (Brass et al. 2009; Nahab et al. 2010; Schnell et al. 2007; Spengler et al. 2009; Yomogida et al. 2010) and has been suggested to contain a mechanism which allows us to determine mismatches in sensory feedback (Tsakiris et al. 2008) and attribution of external cause for events (Seidel et al. 20 10). A second area involved is likely to be the dMPFC, active during agency tasks due to its role similar role in predicting events. (Volz et al. 2003, 2004, 2005). Thirdly, I would also expect so see activation in the pre-SMA, which is involved in the development of intention to create voluntary movements(Picard and Strick 1996). Transcranial magnetic stimulation (tms) supressing neural activity of this area results in a decrease in intentional binding (moore 2010). Although increased blood flow will be present in these areas during all forms of agency experience, these areas have been found to be more strongly associated with external agency attributions; therefore it is possible that I will see more activation of these three regions in the healthy control group. This was suggested as the result of a met-analysis performed by Sperduti, Delaveau, Fossati Nadelfound (2011), recognising that the bilateral insular cortex, premotor and primary somatosensory cortex are only active during the production of voluntary movements (Ciccarelli et al. 2005; Francis et al. 2009; Tatsuya et al. 1999 and therefore experiences of self-agency. The bilateral insular cortex is of particular interest in this study as it has been noted in the impairment of attribution of self-agency in schizophrenic patients, and is correlated with positive symptoms. (Wylie and Tregellas 2010, Voss et al. 2010) Although the high level of comorbidity between Schizophrenia and Pathological Gambling is well documented, the effect of agency has not been studied directly in relation to the disorders, so results are difficult to predict. However, this area of study is worthwhile as it establishes the significance of screening patients with Schizophrenia for gambling disorders and helps to detect the aspects of the population that may place these patients at particular threat of developing pathological gambling. Patients who exhibit both these disorder have been found to respond less favourably to treatment, and may experience longer and more frequent durations in hospital, due to poor response and adherence to medication; this increases both the cost and encumbrance to society. Other negative consequences include increased aggression, alcoholism, depression, homelessness and likelihood of becoming a victim of crime. (Green, Drake, Brunette, Noordsy, 2007, Desai Potenza, 2009). The stress caused by gambling disorders, such as financial and relationship problems, may increase the risk of episodes of psychosis. (Borras Huguelet, 2007) Discovering reliable therapies for this group is of importance for future research because current research trials developing treatment for gambling addictions usually do not permit the inclusion of participant who have been diagnosed with a psychoticdisorder such as Schizophrenia; so far there has been no clinical studies of treatments for individuals with these co-occuring disorders. (Enrique Echeburà ºaa,b,*, Montserrat Gà ³mezc, Montserrat Freixac) 2011. Most significantly, this research could provide insight into the brain regions and theoretical processes involved in the maintenance of gambling disorders, in a population in which it is not only incredibly prevalent but also particularly harmful.

Religion and Prayer in Public Schools Essay -- Exploratory Essays Rese

Religion in Public Schools    The practice of religion has been a major factor in American culture for centuries. The religion clause of the First Amendment, which states "Congress shall make no law respecting an establishment of religion or prohibiting the free exercise thereof," was developed to preserve the freedom of religion (Haynes 2). The religion clause was designed to protect religion from the control of the government, but, consequently, it restricts the expression of religion in public institutions such as public schools. This highly debated issue of religion in public schools is supported by the belief that religion is critical to the formation of a healthy society but is disputed on the basis that the church and the state must remain separate to protect the freedom of religion. Controversies arise over the interpretation of the exact limits of religion in regards to public schools. The religion clause of the First Amendment is often misinterpreted to mean that absolutely no religious expressions or activities can take pl ace in public schools. Richard W. Riley, U.S. Secretary of Education, published a statement in 1995 detailing the principles of the extent to which religious expression and activity are permitted in public schools. He stated that the First Amendment con tains two equally important obligations of public school officials in their dealings with religion. The first is that schools may not forbid students from expressing their own religious beliefs. Schools may not discriminate against religious expressions performed privately by students, but instead they must offer the same right to be involved with religious activities as they would offer to other activities. At the same t... ... regarding the role of religion in public schools will continue to arise as long as people have differences of values and beliefs.    Works Cited Brandt, Ron.

Regional movements that occur in the small intestine and function to churn and fragment the digestive material are called: (a. )segmentation. 9. Bile release from the gallbladder into the duodenum occurs only under the stimulation of: (a. )cholecystokinin. 10. Label the three segments of the small intestine in the following figure. (a) duodenum; (b) jejunum; (c) ileum. 11. The major function(s) of the large intestine is (are): (a. )reabsorption of water and compaction of feces. (b. )absorption of vitamins liberated by bacterial action. (c. )storage of fecal material prior to defecation. (d. )a, b, and c. 12. Vitamins generated by bacteria in the colon are: (c)vitamin K, biotin, and pantothenic acid. 13. The final enzymatic steps in the digestive process are accomplished by: (a. ) brush border enzymes of the microvilli. 14. What are the six steps of digestion? Digestion involves (1. ) ingestion; (2. ) mechanical processing; (3. ) secretion; (4. ) digestion (conversion into a form usable by cells); (5. ) absorption; and (6. ) excretion. 15. Name and describe the layers of the digestive tract, proceeding from the innermost layer to the outermost layer. Layers of the digestive tract are (1. ) the mucosa: the epithelial layer that performs chemical digestion and absorption of nutrients; (2. the submucosa: the connective tissue layer containing lymphatic and blood vessels and the submucosal nerve plexus; (3. ) the muscularis externa: the smooth muscle layer containing the myenteric nerve plexus; and (4. ) the serosa: the outermost layer, epithelium and connective tissue that forms the visceral peritoneum (or connective tissue that forms the adventitia). 16. What three basic mechanisms reg ulate the activities of the digestive tract? Activities of the digestive tract are regulated by neural, hormonal, and local mechanisms. 17. What are the three phases of swallowing, and how are they controlled? The three phases of swallowing—the buccal, pharyngeal, and esophageal phases—are controlled by the swallowing center of the medulla oblongata via the trigeminal and glossopharyngeal cranial nerves. The motor commands originating at the swallowing center are distributed by cranial nerves V, IX, X, and XII. Along the esophagus, primary peristaltic contractions are coordinated by afferent and efferent fibers within the glossopharyngeal and vagus cranial nerves, but secondary peristaltic contractions occur in the absence of CNS instructions. 8. What are the primary digestive functions of the pancreas, liver, and gallbladder? The pancreas provides digestive enzymes, plus bicarbonate ions that elevate the pH of the chyme. The liver produces bile and is also the primary organ involved in regulating the composition of circulating blood. The gallbladder stores and releases bile, which contains additional buffe rs and bile salts that facilitate the digestion and absorption of lipids. 19. Which hormones produced by duodenal enteroendocrine cells effectively coordinate digestive functions? The hormones include the following: enterocrinin, which stimulates the submucosal glands of the duodenum; secretin, which stimulates the pancreas and liver to increase the secretion of water and bicarbonate ions; cholecystokinin (CCK), which causes an increase in the release of pancreatic secretions and bile into the duodenum, inhibits gastric activity, and appears to have CNS effects that reduce the sensation of hunger; gastric inhibitory peptide (GIP), which stimulates insulin release at pancreatic islets and the activity of the duodenal submucosal glands; vasoactive ntestinal peptide (VIP), which stimulates the secretion of intestinal glands, dilates regional capillaries, and inhibits acid production in the stomach; gastrin, which is secreted by G cells in the duodenum when they are exposed to large quantities of incompletely digested proteins; and, in small quantities, motilin, which stimulates intestinal contractions, villikinin, which promotes the movement of villi and associat ed lymph flow, and somatostatin, which inhibits gastric secretion. 20. What are the three primary functions of the large intestine? The large intestine reabsorbs water and compacts the intestinal contents into feces, absorbs important vitamins liberated by bacterial action, and stores fecal material prior to defecation. 21. What two positive feedback loops are involved in the defecation reflex? Positive feedback loops in the defecation reflex involve (1. ) stretch receptors in the rectal walls, which promote a series of peristaltic contractions in the colon and rectum, moving feces toward the anus; and (2. the sacral parasympathetic system, also activated by the stretch receptors, which stimulates peristalsis via motor commands distributed by the pelvic nerves. 22. During defecation, (a. )stretch receptors in the rectal wall initiate a series of peristaltic contractions in the colon and rectum. (b. )stretch receptors in the rectal wall activate parasympathetic centers in the sacral region of the spinal cord. (e. )only a and b occur. 23. Increased parasy mpathetic stimulation of the intestine would result in: (e. )none of these. 24. A drop in pH below 4. 5 in the duodenum stimulates the secretion of (a)secretin. 5. Through which layers of a molar would an oral surgeon drill to perform a root canal (removal of the alveolar nerve in a severely damaged tooth)? A root canal involves drilling through the enamel and the dentin. 26. How is the epithelium of the stomach protected from digestion? The stomach is protected from digestion by mucous secretions of its epithelial lining and by neural and hormonal control over the times and rates of acid secretion. 27. How does each of the three phases of gastric secretion promote and facilitate gastric control? (1. ) The cephalic phase of gastric secretion egins with the sight or thought of food. Directed by the CNS, this phase prepares the stomach to receive food. (2. ) The gastric phase begins with the arrival of food in the stomach; this phase is initiated by distension of the stomach, an incre ase in the pH of the gastric contents, and the presence of undigested materials in the stomach. (3. ) The intestinal phase begins when chyme starts to enter the small intestine. This phase controls the rate of gastric emptying and ensures that the secretory, digestive, and absorptive functions of the small intestine can proceed reasonably efficiently. 8. Nutritionists have found that after a heavy meal, the pH of blood increases slightly, especially in the veins that carry blood away from the stomach. What causes this â€Å"postenteric alkaline tide†? After a heavy meal, bicarbonate ions pass from the parietal cells of the stomach into the extracellular fluid, causing the pH of the extracellular fluid to rise. As the extracellular fluid exchanges ions with the blood, the blood pH also increases. 29. Some people with gallstones develop pancreatitis. How could this occur? If a gallstone is small enough, it can pass through the common bile duct and block the pancreatic duct. Enzymes from the pancreas then cannot reach the small intestine. As the enzymes accumulate, they irritate the duct and ultimately the exocrine pancreas, producing pancreatitis. 30. Harry is suffering from an obstruction in his colon. He notices that when he urinates, the color of his urine is much darker than normal, and he wonders if there is any relationship between the color of his urine and his intestinal obstruction. What would you tell him? The darker color of his urine is probably due to increased amounts of the pigment urobilin, which gives urine its normal yellow color. Urobilin is derived from urobilinogen, which is formed in the large intestine by the action of intestinal bacteria on bile pigments. In an intestinal obstruction, the bile pigments cannot be eliminated by their normal route, so a larger-than-normal amount diffuses into the blood, where it is eliminated by the kidneys. 31. A condition known as lactose intolerance is characterized by painful abdominal cramping, gas, and diarrhea. The cause of the problem is an inability to digest the milk sugar, lactose. How would this cause the observed signs and symptoms? If an individual cannot digest lactose, this sugar passes into the large intestine in an undigested form. The presence of extra sugar in the chyme increases its osmolarity, so less water is reabsorbed by the intestinal mucosa. The bacteria that inhabit the large intestine can metabolize the lactose, and in the process they produce large amounts of carbon dioxide. This gas overstretches the intestine, which stimulates local reflexes that increase peristalsis. The combination of more-fluid contents and increased peristalsis causes diarrhea. The overexpansion of the intestine by gas, which is directly related to increased gas production by the bacteria, causes the severe pain and abdominal cramping. 32. Recently, more people have turned to surgery to help them lose weight. One form of weight control surgery involves stapling a portion of the stomach shut, creating a smaller volume. How would such a surgery result in weight loss? The primary effect of such surgeries would be a reduction in the volume of food (and thus in the amount of calories) consumed because the person feels full after eating a small amount. This can result in significant weight loss. CheckPoints Page 882 1. Identify the organs of the digestive system. Organs of the digestive system include the esophagus, stomach, small intestine, large intestine, and accessory organs (salivary glands, liver, and pancreas). 2. List and define the six primary functions of the digestive system. The six primary functions of the digestive system include the following: (1) ingestion = consciously eating food; (2) mechanical processing = crushing and shearing foodstuffs to make them more susceptible to enzymatic attack; (3) digestion = the chemical breakdown of food into smaller products for absorption; (4) secretion = the release of water, acids, and other substances by the epithelium of the digestive tract and by glandular organs; (5) absorption = movement of digested particles across the digestive epithelium and into the interstitial fluid of the digestive tract; and (6) excretion = the removal of waste products from the body. . What is the importance of the mesenteries? The mesenteries—sheets consisting of two layers of serous membrane separated by loose connective tissue—support and stabilize the organs in the abdominopelvic cavity and provide a route for the associated blood vessels, nerves, and lymphatic vessels. 4. Name the layers of the gastrointestinal t ract from superficial to deep. The layers of the gastrointestinal tract, from superficial to deep, are the serosa, muscularis externa, submucosa, and mucosa (adjacent to the lumen). 5. Which is more efficient in propelling intestinal contents from one place to another: peristalsis or segmentation? The waves of contractions that constitute peristalsis are more efficient in propelling intestinal contents than segmentation, which is basically a churning action that mixes intestinal contents with digestive fluids. 6. What effect would a drug that blocks parasympathetic stimulation of the digestive tract have on peristalsis? A drug that blocks parasympathetic stimulation, which increases muscle tone and activity in the digestive tract, would slow peristalsis. Page 888 7. Name the structures associated with the oral cavity. Structures associated with the oral cavity include the tongue, salivary glands, and teeth. 8. Which type of epithelium lines the oral cavity? The oral cavity is lined by a stratified squamous epithelium, which provides protection against friction or abrasion by foodstuffs. 9. The digestion of which nutrient would be affected by damage to the parotid salivary glands? Damage to the parotid salivary glands, which secrete the carbohydrate-digesting enzyme salivary amylase, would interfere with the digestion of complex carbohydrates. 10. Which type of tooth is most useful for chopping off bits of relatively rigid foods? The incisors are the teeth best suited for chopping (or cutting or shearing) pieces of relatively rigid food, such as raw vegetables. 11. Where exactly in the human body is the fauces? The fauces is the dividing line between the oral cavity and the pharynx. 12. Describe the structure and function of the pharynx. The pharynx is an anatomical space that receives a food bolus or liquids and passes them to the esophagus as part of the swallowing process. 13. Identify the muscles associated with the pharynx. Muscles associated with the pharynx are pharyngeal constrictor muscles, the palatopharyngeus and stylopharyngeus muscles, and palatal muscles. Page 890 14. Name the structure connecting the pharynx to the stomach. The structure connecting the pharynx to the stomach is the esophagus. 15. Compared to other segments of the digestive tract, what is unusual about the muscularis externa of the esophagus? The muscularis externa of the esophagus is an unusual segment of the digestive tract because it (1) contains skeletal muscle cells along most of the length of the esophagus and (2) is surrounded by an adventitia rather than a serosa. 6. What is occurring when the soft palate and larynx elevate and the glottis closes? When the soft palate and larynx elevate and the glottis closes, swallowing (deglutition) is occurring. Page 897 17. Name the four major regions of the stomach. The four regions of the stomach are the cardia, fundus, body, and pylorus. 18. Discuss the significance of the low pH in the stomach. The low pH of the stomach creates an acidic environment that kills most microbes ingested with food, denatures proteins and inactivates most enzymes in food, helps break down plant cell walls and meat connective tissue, and activates pepsin. 9. How does a large meal affect the pH of blood leaving the stomach? Large (especially protein-containing) meals stimulate increased stomach acid secretion. Because the hydrogen ions of stomach acid come from blood entering the stomach, blood leaving the stomach will have fewer hydrogen ions and thus a higher pH. This phenomenon is referred to as the alkaline tide. 20. When a person suffers from chronic gastric ulcers, the branches of the vagus nerves that serve the stomach are sometimes cut in an attempt to provide relief. Why might this be an effective treatment? The vagus nerves contain parasympathetic motor fibers that can stimulate gastric secretions, even if food is not present in the stomach (the cephalic phase of gastric digestion). Cutting the branches of the vagus nerves that supply the stomach would prevent this type of secretion from occurring and thereby reduce the likelihood of ulcer formation. Page 910 21. Name the three regions of the small intestine from proximal to distal. The three regions of the small intestine are the duodenum, jejunum, and ileum. 22. How is the small intestine adapted for the absorption of nutrients? The small intestine has several adaptations that increase its surface area and thus its absorptive capacity. The walls of the small intestine are thrown into folds, the plicae circulares. The tissue that covers the plicae circulares forms fingerlike projections, the villi. The cells that cover the villi have an exposed surface covered by small fingerlike projections, the microvilli. In addition, the small intestine has a very rich supply of blood vessels and lymphatic vessels, which transport the nutrients that are absorbed. 23. Does a high-fat meal raise or lower the level of cholecystokinin in the blood? A high-fat meal would raise the cholecystokinin level in the blood. 24. How would the pH of the intestinal contents be affected if the small intestine did not produce secretin? The hormone secretin, among other things, stimulates the pancreas to release fluid high in buffers to neutralize the chyme that enters the duodenum from the stomach. If the small intestine did not secrete secretin, the pH of the intestinal contents would be lower than normal. 25. The digestion of which nutrient would be most impaired by damage to the exocrine pancreas? Damage to the exocrine pancreas would most impair the digestion of fats (lipids), because it is the primary source of lipases. Even though such damage would also reduce carbohydrate and protein digestion, enzymes for digesting these nutrients are produced by other digestive system structures, including the salivary glands (carbohydrates), the small intestine (carbohydrates and proteins), and the stomach (proteins). Page 916 26. Identify the four regions of the colon. The four regions of the colon are the ascending colon, transverse colon, descending colon, and sigmoid colon. 27. What are some major histological differences between the large intestine and the small intestine? The large intestine is larger in diameter than the small intestine, but its relatively thin wall lacks villi and has an abundance of mucous cells and intestinal glands. 28. Differentiate between haustral churning and mass movements. In mass movements, which occur a few times per day throughout the transverse colon and the distal portions of the large intestine, strong peristaltic contractions move material along the length of the colon. In haustral churning, segmentation movements mix the contents of adjacent haustra. Page 921 29. What kinds of nutrients does the body require? Nutrients required by the body are carbohydrates, lipids, proteins, vitamins, minerals, and water. 30. What component of food would increase the number of chylomicrons in the lacteals? Because chylomicrons are formed from the fats digested in a meal, fats increase the number of chylomicrons in the lacteals. 31. The absorption of which vitamin would be impaired by the removal of the stomach? Removal of the stomach would interfere with the absorption of vitamin B12, a process that requires intrinsic factor, produced by the parietal cells of the stomach. 2. Why is it that diarrhea is potentially life threatening, but constipation is not? When an individual with diarrhea loses fluid and electrolytes faster than they can be replaced, the resulting dehydration can be fatal. Although constipation can be quite uncomfortable, it does not interfere with any life-supporting processes; the few toxic waste products normally eliminated by the digestive system can move into the blood and be eliminated by the kidneys. Page 922 33. Identify general digestive system changes that occur with aging. General age-related digestive system changes include decreased secretory mechanisms, decreased gastric and intestinal motility, decreased mitotic activity of epithelial cells, and loss of tone; cumulative damage becomes more apparent, cancer rates increase, and dehydration occurs as a result of decreased osmoreceptor sensitivity. 34. Identify the functional relationships between the digestive system and other body systems. The digestive system absorbs the organic substrates, vitamins, ions, and water required by cells of all other body systems. 35. What body systems may be affected by inadequate calcium absorption? The skeletal, muscular, nervous, endocrine, and cardiovascular systems may all be affected by inadequate absorption of calcium. Review Questions Labeling 1.

Section 2: Concept Review Now let's see what you have learned about Digestion and Absorption. I will give you a question and two possible answers. Then I will pause while you consider the choices and select your answer. After a few seconds, I will give you the correct answer with an explanation. Question 1 Enzymes and buffers are considered part of which type of digestion? Is it A) mechanical or B) chemical? The answer is B) chemical. Mechanical digestion involves mixing, churning, and chewing. Question 2 What do we call movement of food without direction in the digestive tract? Is it A) peristalsis or B) segmentation? The answer is B) segmentation. Peristalsis is the movement of food forward through the digestive tract. Question 3 Where does major absorption of food substances occur? Is it in A) the stomach or B) the small intestine? The answer is B) the small intestine. Almost all absorption occurs in the small intestine. Question 4 Which type of enzyme digests carbohydrates? Is it A) amylase or B) peptidase? The answer is A) amylase. Peptidase breaks down proteins. Question 5 Which side of the epithelial cells lining the digestive tract faces in towards the lumen? Is it A) apical or B) basal? The answer is A) apical. The basal surface fuses the cells to the deep tissues. Question 6 What is the term for emulsified, digested lipids? Is it A) chylomicrons or B) micelles? The answer is B) micelles. Chylomicrons are cholesterol-fat complexes that have a protein coating. Question 7 Which portion of the small intestine serves as a mixing bowl for substances from the pancreas, liver, and stomach? Is it A) the duodenum or B) the ileum? The answer is A) the duodenum. As the food enters the small intestines, enzymes, buffers, and bile also enter at the duodenum Question 8 In which part of your digestive system is most of the water reabsorbed? Is it A) the colon or B) the small intestine? The answer is B) the small intestine. Up to ninety-five percent of the water entering the digestive tract is absorbed here. That's the end of this section. Section 3: Rapid Review Now we will do a quick set of review questions on Digestion and Absorption.
