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 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.

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. I will give you a question and then only a couple of seconds to give your answer. After a brief pause, I will give you the correct answer. Let's start with some true or false questions. Question 1 True or false? Bile is produced by the gallbladder. Answer: False Question 2 True or False? Once food is digested in the stomach, it is called chyme. Answer: True Question 3 A chylomicron is an example of a digested protein. Answer: False Okay, now let's try some multiple choice questions. Question 4 Which substance is absorbed through the intestinal lining? Is it A) monosaccharides or B) nucleic acids? Answer: A) monosaccharides Question 5 What is the term for breaking down lipids? Is it A) lipogenesis or B) emulsification? Answer: B) emulsification Great! Now let's try some short answer questions. Question 6 Which accessory organ produces amylases, lipases, buffers, and hormones? Answer: The pancreas Question 7 Most of the fat absorption occurs in which part of the small intestine? Answer: The ileum Question 8 Where does the process of chemical digestion start? Answer: In the mouth That's the end of this section.

The short story â€Å"A New Leaf† by F. Scott Fitzgerald rang many alarms for me the first being I found myself completely stumped in the matter of which form of fiction this specific piece was written. I personally found it highly entertaining like that of commercial fiction yet I can definitely see the potential message behind the story to get a meaningful lesson across. â€Å"A New Leaf† is so entertaining for me because it is literally one of the pieces you can see in your head as you are reading it.My personal favorite moment was envisioning just how Julia felt as she went dancing in the evenings with Mr. Ragland. I picture it as something magical like every moment she is with him the rest of the world melts away. She is completely content with a night just enveloped in Ragland’s arms all the while he fights the temptation of having another drink in her presence. I think the overall tone of the story could be taken as literal fiction.The main message being p atience is a virtue or sometimes it can be better to let someone hold on to a small glimmer of hope for the common good than to crush their spirits with the absolute truth. I personally believe sometimes it is greater to let someone believe a small lie than to kill their belief in their own ability to find hope. Phil is the main demonstrator of both of my points. In the story he waits for Julia obviously loving her throughout the whole story. He lets her make her own decision to stay with Dick in the beginning of the story although it was against his will and better judgment.Later in the story he comes back into the story not to hurt Julia with the knowledge of Dick’s shortcomings and foolery but as a friend with a warning. Through all of this Paul shows great restraint and immense love for Julia; he waits for the time to be right to confront Paul in a private fashion. Finally knowing all of Dick’s dirty secrets after his death Paul still refuses to tell Julia she was wrong about Dick all along. He did not take away joyful feelings that Julia felt about Dick dying trying to change his lifestyle even though he knew the real truth all along. Mike The short story â€Å"A New Leaf† by F.

Cunto invertir para obtener visa E-2 de inversionista

Cunto invertir para obtener visa E-2 de inversionista   Las leyes de inmigracià ³n de Estados Unidos no dicen especà ­ficamente quà © cantidad de dinero hay que invertir en un negocio para que se obtenga la aprobacià ³n de la visa E-2 por inversià ³n. Simplemente una inversià ³n sustancial para el negocio que se desea emprender. Pero,  ¿cunto una inversià ³n es sustancial? Para la mayorà ­a de los abogados de inmigracià ³n Muchos de los expertos que se han especializado en este tipo de visas consideran que las inversiones a partir de los $100,000 tienen oportunidades reales de ser aprobadas y que a partir de los $250,000 es, realmente, un caso muy fuerte para su obtencià ³n.  ¿Es posible obtener la visa E-2 con una inversià ³n inferior a los $100,000? Sà ­, hay numerosos casos en los que se ha obtenido con inversiones en torno a los $40,000-$50,000. Depende del tipo de negocio e Inmigracià ³n no va a pedir a un posible inmigrante extranjero que invierta una cantidad superior que la que invertirà ­a un ciudadano americano para el mismo tipo de negocio. En estos casos se recomiendan dos cosas: primero, contar con un buen abogado que crea en el proyecto. A la hora de elegirlo es posible que se tenga que realizar entrevistas previas con varios de ellos. Y segundo, tener un excelente plan de negocios y entenderlo y buscar el tipo jurà ­dico de empresa correcto de los 10 posibles en Estados Unidos. Es fundamental arriesgar dinero real y estar dispuesto a ello (se trata de un negocio), tomarse el tiempo para estudiar quà © se quiere hacer, en dà ³nde, cules son los posibles clientes, cà ³mo obtenerlos, quà © diferencial puede ofrecer el negocio, etc. A la hora de confeccionar el plan de negocios y la carta de presentacià ³n que le acompaà ±a es muy comà ºn contar con la ayuda de profesionales que entienden de nà ºmeros y los aspectos tà ©cnicos. Pero aà ºn en los casos en los que se encarga la redaccià ³n del plan de negocios es fundamental entenderlo, tomarlo como un asunto propio. Otra buena opcià ³n es abrir una franquicia con un modelo de negocio probado. Estas son las 10 franquicias consideradas como las mejores en USA. Si se est pensando en una inversià ³n inmobiliaria, es muy importante asesorarse bien ya que debe tener forma de negocio real y activo para que pueda calificar.  ¿Dà ³nde es frecuente que surjan problemas en el proceso de tramitacià ³n de la E-2? Una vez que el Servicio de Inmigracià ³n y Ciudadanà ­a (USCIS, por sus siglas en inglà ©s) aprueba la solicitud, es necesario pasar una entrevista en el consulado (o Embajada) del paà ­s en el que se reside.   La entrevista es dura. El oficial consular (llamado cà ³nsul en algunos paà ­ses), va a querer quedar convencido de que la persona que solicita la visa tiene capacidad para sacar adelante un negocio, que lo entiende, y para eso va a hacer preguntas en profundidad sobre el plan de negocios. Asimismo, va a querer quedar convencido del origen legal de la inversià ³n y evitar casos que persigan actividades delictivas como blanqueo de dinero.  ¿Cunto cobra de media un abogado de inmigracià ³n por completar planilla de solicitud de E-2? Unos $5,000, generalmente se puede negociar pagarlo en distintos plazos. Adems, hay que sumar el pago por llenar las planillas de cada miembro de la familia que acompaà ±e al inversor.   Asimismo hay que tener en cuenta que se pueden generar otros gastos, como por ejemplo, la elaboracià ³n del plan de negocios, que puede costar en torno a $2,500 dependiendo de las circunstancias de cada caso. Otros gastos que pueden influir son los relacionados con la creacià ³n de la empresa, si todavà ­a no se ha hecho y se encarga al mismo despacho de abogados. Los precios por lo general estn fijados, pero van a variar un poco si se contratan varias gestiones como presentacià ³n papeles visa, creacià ³n de empresa y elaboracià ³n de plan de negocios o sà ³lo una. Tambià ©n influye en el precio si el abogado debe buscar papeles o se le proporcionan todos y si ya estn en inglà ©s o los hay que traducir. Tambià ©n es comà ºn que se cobre una cantidad por la consulta que puede oscilar habitualmente entre los $200 - $400 y, si se sigue adelante, se descuente del total. Es decir, saldrà ­a gratis pero sà ³lo si se sigue el caso con ese despacho de abogados. Puede resultar de interà ©s cunto  cobra un abogado de inmigracià ³n para otros asuntos. Tener en consideracià ³n que eso son medias y que existen grandes diferencias segà ºn el prestigio de los despachos y tambià ©n segà ºn el lugar donde radian. De interà ©s para emprendedores que desean emigrar a USA La visa E-2 es parecida, pero diferente, a la E-1 para comerciantes de importacià ³n/exportacià ³n. Si se tiene un negocio de ese tipo. Si ese es el caso, explorar esa posibilidad. Otras opciones son estas  8 posibles visas para crear un negocio en Estados Unidos  y si se tiene al menos medio millà ³n de dà ³lares, explorar cà ³mo obtener la  green card por inversià ³n: EB-5. En todo caso, antes de invertir informarse sobre las leyes en diferentes estados porque la regulacià ³n es muy distinta en diferentes partes del paà ­s siendo estos los 10 mejores estados para hacer negocios. Si se est abierto a otras opciones diferentes a Estados Unidos, estos son 20 paà ­ses en los que es posible adquirir la ciudadanà ­a (pasaporte) y/o la residencia por inversià ³n.

Canopic Stopper of King Tut

A lot of different statuettes, busts, vases, elements of decorations, etc. from those times were presented at the exhibition in Los Angeles County Museum of Arts. But I was especially fascinated with a little bust from the canopic chest of King Tut, made of delicately patterned transparent calcite. This elegant bust reproduces King Tut himself wearing the nemes head-dress. The creators of it used subtle black and red paints to underline facial details of good-looking Egyptian king: his big eyes, eyebrows and lips, demonstrating feminized nature of this person. Traditionally, the face of King Tut is presented with decorations of protective cobra and vulture, appearing from his head-dress. This small statuette is typical exemplar of Egyptian ancient art, which is characterized with features of early frontalism: every picture (in painting) or figure (in sculpture) was presented in rigid and formal posture. This bust was found in a shrine of King Tut, on a magnificent canopic chest made of alabaster and gorgeously decorated with golden staples. There were, actually, four of such busts, which were located in every corner of the chest and served as stoppers. These stoppers were sealing four compartments of the chest, in which four miniature anthropomorphic coffins, containing mummified inner organs of the king, were stored. King Tut (Tutankhamen) is one of the most known and recognizable pharaohs of Ancient Egypt. He was the Ruler of the Eighteenth Dynasty of Egyptian Kings, who started his reign in the age of 9 and died at the age of 19. Certainly, he ruled under supervision and control of his adult advisers: in particular, his vizier and future successor Ay. The main social reconstruction, made by King Tut, is conversion of heretical Atenism, launched by his predecessor King Akhenaton, to previous traditional ancient Egyptian religion. Causes of his death still remain unknown, and there are some suggestions on this issue. Some specialists consider him to be murdered; the others consider his death to be accidental. After watching this sculpture of young pharaoh for some long period of time, first of all, I started paying more attention on its divine material. This transparent calcite is called Egyptian alabaster, which was, probably, enriched with some phosphoric materials. That is why the bust looks so lucid and shining, as if time did not touch it at all. I noticed that in this magic shining the representation of King Tut looked exceptionally graciously, and he seemed to me to be very calm and friendly as a person. The more I watched, the more I could realize, how different it is to see figures and statues in real dimensions, not as reproductions in the books. This way so many details, like features of the face, head position, profile line, vivid natural colors, and so on, can be better observed and considered. There is no printed picture, which can properly show the light, color, shape or delicacy of ancient artworks. So, if we want to receive some good idea about such treasures, we have to see them live. That is why such exhibitions are extremely popular and always crowded. There are many known representations and images of King Tut, which remained from ancient times. Recently the revolutionary event took place, when the team of Egyptian, American and French specialists managed to receive a new facial image of Tutankhamen. It was presented in three-dimensional CT scans of the Pharaoh’s skull, but the only uncertainty was left, which is the tone of King Tut’s skin. Of course, such researches are priceless. But, to my mind, there is no better imagination of a historical personage, than the one, which can be received from observing original artworks and genuine historical materials. After visiting this exhibition, I have formed my own clear picture of this Egyptian legendary king in my mind, which, I suppose, is not very different from his real appearance and character.

Describing demonstrative communication. Demonstrative communication Essay

Describing demonstrative communication. Demonstrative communication includes nonverbal and unwritten communication and involves such things as facial expressions, tone of voice, body language, and so forth - Essay Example In demonstrative communication, the sender sends the right message and the receiver captures and understands it well before responding. Moreover, in demonstrative communication, individuals receive information through their senses and then create communication in form of facial expressions, body languages, eye gazes and blinking of the eyes among others (Cheesebro, O’Connor & Rios, 2010). As defined earlier, demonstrative communication refers to nonverbal or unwritten communication. Therefore, this type of communication involves sending and receiving wordless messages from the sender to the receiver. Demonstrative communication is effective or positive at workplace because it reinforces verbal communication, for example dressing properly, friendly demeanor and firm handshake at work place shows more information concerning thecharacter of an individual during job interviews. Most people at work place highly rely on these qualities in reinforcing the verbal performance. Demonstrative communication is effective at work place because an employee can tell that the other employee is friendly by the way he or she smile and speak in a cheerful manner(Cheesebro, O’Connor & Rios, 2010). Demonstrative communication is effective and positive at work place because it helps an individual in knowing what other people think about him or her because of the nonverbal signals that they exude. In addition, people can apply demonstrative communication at workplace in order to analyze people’s reactions for their own advantages. For example, when an organization specializes in selling houses and when they tell a client about the price for the house, the client’s reaction will help an organization in determining whether the price is accommodative or not. Demonstrative communication is beneficial at work place because it gives room for self-expression, whereas self-presentation tells more about and individuals’ personality. For example, in a workplace, a

Components of metaphors Essay Example | Topics and Well Written Essays - 3000 words

Components of metaphors - Essay Example Using our example above, the eagle is the topic of the metaphor. Vehicle: This refers to both the expression and concepts that are called upon by the words i.e. the term that is being used metaphorically or non-literally. Using our example above, the lion is the vehicle of the metaphor. Grounds: This refers to the relationship between the topic and the vehicle. There is a relationship between the lion and the eagle. This is in relation to the strength of the lion and the tenacity of the eagle which is being used as the ground that supports this metaphor. The tenacity of an eagle is being equated to the strength of the lion. b) Explain the claim that metaphor is found in most writing very frequently. Illustrate with examples taken from the attached text about Jack Ashley (Appendix A). The metaphor is a powerful language tool as well as being a quite complex one too. Metaphors are powerful tools to give ideas to people that they will always remember. This is one of the reasons why the metaphor is found in writing very frequently. Metaphors are also great tools of imagery. Imagery refers to the method whereby a writer would utilise words that paint pictures of scenes and characters in the minds of their readers. In this age of expanded imagination, writers have had to adopt metaphorical writing to enable the reader to actually experience the scene as well as the characters in the story. Metaphors are one of the effective tools in writing fiction. They give life to the normally dull prose thus their frequent use. With these features, it is very easy to see why the claim that metaphors are found in most writing very frequently is quite true. We have sought metaphorical examples from the Jack Ashley text as below: ‘If the media is a smug insiders club’: The metaphorical component of this metaphor refers to the media as the topic of discussion. The vehicle would be the insider’s club while the ground for this is equating the smugness of the insider ’s club to the current media characteristics. ‘Britain seems much more of a stitched-up country’: The metaphorical component of this metaphor refers to the Britain as the topic of discussion. The vehicle would be the stitched-up country while the ground for this is equating the characteristic of the new Britain to the perpetual collusions between the wealthiest and most powerful citizens. ‘Parliament starts to feel like a fig leaf for things as they are’: The metaphorical component of this metaphor refers to the parliament as the topic of discussion. The vehicle would be the fig leaf while the ground for this is equating the characteristic of parliament to the fig leaf. A fig leaf is construed as a devise intended to conceal something regarded as shameful therefore equating the parliament to it, means that without the backbenchers and strong journalism, parliament would be a shameful institution. B. Comment on the teaching implications. How could sui table materials be designed to enhance intermediate students’ ability to understand metaphorical language, to re-use metaphors they have seen before appropriately in new contexts, and to know about metaphor in general? You may refer to examples of effective or ineffective materials from existing EFL textbooks if you wish; if so please include a copy of the relevant section. Difficulties are encountered by

History of slavery Research Paper Example | Topics and Well Written Essays - 500 words

History of slavery - Research Paper Example One cannot ignore the fact that if the South did not declare succession, Lincoln would have not declared war in the south. James McPherson, an expert in this subject, and the author of The Battle Cry of Freedom: The Civil War Era insists, â€Å" In July 1861, the U.S. House of Representatives passed a resolution, by a nearly unanimous vote, that affirmed that the North was not waging the war to overthrow slavery but to preserve the Union.† (McPherson 66). Clearly, the focal point of the war was to keep the unity of nation for the sake of peace and security. The events that lead to civil war was the Mexican war, the dependence of the North on the South, the slavery issue, and the Dred Scott decision. Post Mexican War, America was segmented into many territories. This posed a problem as both the North and the South had to manage the issue of slavery. A Band-Aid issue was delivers as Congress passed the Compromise of 1850 which California became a free state. The Fugitive Slave Act of 1850 also did facilitate the cause as the South despised this form their Northern Counterparts (Jordan 36). From the South’s perspective, it is clear that that nation was interested in its own political and economic pursuits. Clearly, the soldiers understood that the North had little or no interest in South’s domestic affairs. Slavery was vital towards the success of South’s economy. The failure for the North to acknowledge the idea motivated the Southern soldiers to pursue their own version of the â€Å"American Dream.† The major political and economic interests between North and South continued to reflect the justification for separation for the Southern soldiers. In midst of this chaos, states such as: South Carolina, Mississippi, Florida, Alabama, Georgia, Louisiana, and Texas had already declared to be seceded soon after during 1855 (Stanchak 26). After this, the major cause that triggered civil war according to historians was also because of Dred Scott

Sensitivity report Coursework Example | Topics and Well Written Essays - 1000 words

Sensitivity report - Coursework Example These resources are the machine time for this case as profits for the products is not sought as a solution to the company’s problem of finding the best combinations for the products. With regards to the three resources available in this analysis, they represent hours at the machines’ disposal. However, it is observed that, it more hours per machine were allowed, then higher total profits would be increase immensely. In order to answer questions like whether it is reason for the company to invest in more machine hours, should the company be willing to pay for more manufacturing time, and whether is profitable to hike the production hours. Using the solver solution represented as table 1, these questions and how they relate to the right combinations for product production can be identified. Using a theoretical analysis approach, it is by design that changes in right-hand-side of the constraint; a corresponding change is registered not unless it is conditional that the con straint is redundant. This translates to a change in the optimal solution as well. With regards to the reduction of hours the machines time may result to a increase of decrease in profit per hour. The change in profit per hour is referred to as the shadow price and is therefore used to determine whether the company should consider investing in more machine hours or a better combination of the produced products. To a constraint, the shadow price represents the improvement to the functional objective that may be a product of one-unit increase within the constraints right-hand-side. With regards to the fact that the profits generated per hour in normal circumstances is ?0.33333 the right combinations of the products are desired in order to preserve the need for increasing machine time. Hence fore, the fact that the company’s profit increased with ?0.3333 for every additional hour, it means that more product B types should be considered if time alone is to be considered. However, while the value of one product A is 24 Sterling Pounds and that of product B is 4 sterling pounds. Therefore, it is also observed that for every single product A a profit of 2 sterling pounds is made as compared to the 4 sterling pounds’ profit on product B. However, given that product A produces at machine at for four hours and two hours at machine B. The total amount of products producible at machine A will be 30 products with regards to the count of four hours for a machine allowance time of 120. On the other hand, the same product can process at machine B for two hours against the allowed duration of 72 hours to give 36 products A. With reference to product B, out of the allowed machine hours for machine A, 120 hours, only 20 product Bs can be produced within the time limit of 6 hours per product. This means that on the other hand, the only 12 product Bs can be produced using machine B speed of 6 hours per product against the allowed timeframe of 72 hours. In this case, since hours are constant and the company does not need to increase machine hours in order to keep investment at the original figure. This means that for product A to be processed within the time frame allowed for machine A and B will translate to a profit of ?60 per hour when processed in machine A and ?72 when process by machine B. On the case of product B, the solver solution shows that for all products B producible in machine A will yield a profit of ?80 with respect to the ?4 profit margin for every unit of

Usefulness of Hofstedes National Culture model Essay

Usefulness of Hofstedes National Culture model - Essay Example The main categories include masculinity versus femininity, individualism versus collectivism, uncertainty avoidance, and power distance. Globalization, which is a concept of free trade, has made the world an increasingly intimate place. Intimacy, in this sense, refers to mutual interdependence that countries possess in both cultural and business terms. The 17th and the 18th century trade made businesspersons realize the different potential and benefits that various countries possessed. Furthermore, the ideas of people such as Adam Smith and David Ricardo quantified the prospects of free trade and globalization. However, besides the raw economic benefit of world trade, businesses realized the essence of culture in understanding the behavior of employees and given market. Culture could act either as an impediment or a propeller of business. The Geert Hofstede model is helpful to business organizations in numerous ways. To begin with, the model may help a business organization comprehend the power structures of a society towards designing a corresponding administrative model. In many business organizations, employees constantly question what makes up a good leader. Unfortunately, Geert Hofstede uncovers that there is no particular way of leading a group. Despite the developments of knowledge documents on management, existing cultural conditions influence the attitudes towards power. The concept of power distance helps an organization comprehend the tolerance of a given society towards power inequality. Large power distance societies manifest a greater tolerance towards power inequality in institutions. In this sense, affected organizations should develop administrative structures that possess clear separation of powers (Piepenburg 2011, p. 178). The managers, thus, should acquire considerable power over the employees, w ho are expected to be utterly subordinate to the seniors. Such a culture, therefore,

Client Paper Essay Example for Free

Client Paper Essay Human service professionals, or helpers, will likely work with many different clients, each with their own set of problems. These problems can range from physical abuse and neglect, aging issues including death and dying, and a number of other issues concerning the basic needs of life. Problems can also encompass the many different situations people find themselves in either as a result of life choices or out of no fault of their own. These problems may include homelessness, combat veteran issues, and mental illness. Whatever the problem or problems are, it is the responsibility of the helper to use a wide range of skills to assess client needs, create a treatment plan, and offer resources and emotional support to the client as they accomplish the goals included in the treatment plan. These skills include communication, empathy, compassion, patience, analytical skills, and teamwork. A range of problems faces human services clients â€Å"Problems for clients are rarely single issues, and the human service professional should approach each client with the expectation of more than one problem.† (Woodside McClam, 2011, p. 131) Every problem that a client presents with cannot be predicted. In fact, client problems encompass a wide range of needs and circumstances. For example, a client who is struggling with domestic violence may also have a need for mental health support. A client with mental health issues may also be experiencing a lack of food, clothing or shelter. The problems facing clients are very broad and it is helpful to better understand them. Problems facing children and families include physical and sexual abuse, poverty, lack of a healthy home, or little education. Children are especially vulnerable as they cannot provide for themselves. Although â€Å"[t]he best place to serve kids is in their home and with a family,† there may be a necessity for placement in foster care or, in some ca ses, adoption (Moffat, 2011, p. 5). The elderly also face  unique problems such as lack of mobility, losing their independence, and end of life issues. When the elderly can no longer care for themselves, finding in-home care or placement in assisted living or nursing home facilities becomes the focus. In addition, the elderly may struggle with some of the basic needs of life such as food, shelter and clothing. Immigrants, veterans, and people with disabilities face other problems in the human service field. Immigrants struggle with adapting to a new culture in a new country as well as learning a new language. Immigrants may have problems with finding employment, housing, and legal help, as well. Veterans need assistance with adjusting to civilian life including adjusting their skill sets to match employment opportunities. Combat veterans especially struggle with physical and mental disabilities and are in need of appropriate services for rehabilitation. Disabled people face challenges in personal care as well as employment, including issues with rehabilitation and adapting to their disabilities. The need for residential or group care facilities may also be at issue for the disabled community. Problems with substance abuse and addiction, mental illness, and clients with criminal records also exist. Many of these problems co-exist in a client’s life and need to be addressed as a whole. â€Å". . . the client is an individual comprised of psychological, social, economic, educational, vocational, and spiritual dimensions and possibly will have needs in many of those areas.† (Woodside McClam, 2011, p. 132) Specific helping skills can be used with clients Essential to the helping process is knowledge and practice of professional and interpersonal skills that help the human service professional in effectively addressing the needs of clients. These skills include communication, empathy, compassion, patience, analytical skills, and teamwork. Chief among these are interpersonal and communication skills, because more workers deal directly with a variety of people† (Moffat, 2011, p.9). The work of human service professionals centers on building relationships of trust with the client. It is the responsibility of the helper to facilitate effective communication. Listening is vital to the process. In order to fully grasp the client situation, the helper needs to observe both the verbal and nonverbal messages. Listening involves paying  attention to both words and actions as they go hand in hand in understanding the total message being given. G.E. Egan introduced the SOLER concept for responsive listening. Learning this concept can be v ery useful to the human service professional (Egan, 2010). Details of the SOLER concept are illustrated in the following table: S Face client Squarely O Adopt an Open posture L Lean toward the person E Maintain good Eye contact R Try to be relatively Relaxed In addition to the SOLER method, paying attention to vocal tone and speech rate, and verbal tracking of the client’s message will exhibit attending behavior and help the communication process (Ivey, Ivey Zalaquette, 2009). The helper can encourage the client to discuss their issues openly by not changing the subject they have chosen. Effective listening shows compassion for the client and creates an opportunity to show empathy and patience, additional skills that are essential to the success of the human service field. Clients in the human service field come from a variety of situations. Their values and belief systems vary widely as much as their problems do. In order to effectively help people, helpers need to develop acceptance and understanding of these differences. Unconditional acceptance of the client is essential to the success of treatment. Helpers need to see the situation and experience feelings from the perspective of their client. Patience is necessary for the he lping process as there are likely to be setbacks or resistance to the treatment plan. Helpers should learn to adapt their approach as the situation changes; which leads to the skill of critical thinking. â€Å"The ability to think creatively helps workers determine ways to get around hurdles that interfere with clients’ efforts to succeed† (Moffat, 2011, p.10). Throughout the helping process, a variety of changes is bound  to occur. Whether these are positive or negative changes, client and human service professional must work together to deal with them and continue to move forward with the assistance process. Using analytical and problem-solving skills, helpers can overcome the roadblocks to treatment and continuously work towards solutions. Treatment often involves networking with a number of other professionals and utilizing a variety of resources. Being able to work well as a team is another essential skill for human service professionals. Psychologists, Social Workers, Mental Health Facilitators and Counselors are all participants in the work of h uman services. Using communication, empathy, compassion, patience, analytical skills, and teamwork, the helper can effectively recognize and define the variety of client problems that exist and work with them towards accomplishing the goal of the helping process, which is to encourage responsibility and promote self-help.
