Information tech - Essay Example ed on the behavioral aspects of management accounting information, management accounting information is a necessity in business due to its capacity to change the financial position and performance of business. This has an impact on managers responsible for drawing business objectives since they are the major users of such information (Vitez 196). Depending on the level of information details available, business management decisions are based on good management information system and are only as good as how well and current information is provided. Fulfillment of business objectives is based on critical decisions, and not guesses work about elements such as budgets and costs. Through maintaining a good management accounting system, managers are able to spruce up their probability of making ideal business decisions. Even though information may not be the only key thing in business, it provides a real important component in decision making process (Vitez 198). Therefore providing inform ation improves the quality of decisions which result to actions that contribute to the fulfillment of the objectives of the business in the best way possible. In summary, providing management accounting information will not only improve the quality of business decision making, but also increase business efficiency, maximize profitability, simplify financial statement, control the cash flow of the business, increase financial reforms, reduce expenses, and solve problems and conflicts, and better financial reporting (Vitez

707 week 6 - Assignment Example It is however relatively expensive, has limited scope, and may be susceptible to environmental factors. Interviews involves oral presentation of prompts to which a research participant respond and could be face to face or involve the use of technologies such as phones or computer and internet applications for oral and visual communication over long distances. Unlike in observation, interviews involve the research participants and therefore induce threats of participant bias though it offers more in-depth information. Questionnaires, however, have written prompts and establish a distinction between a researcher and research participants. It is less expensive, convenient, and flexible, and the use of technology, such as in online enhances these advantages (Kothari, 2004). A research aims at developing knowledge, from existing data, for solving a problem or bridging information gap and reliability and validity ensures realization of the aims. Reliability defines consistency in data and ensures that results and implications are consistent with identified problem while validity ensures accuracy in knowledge development for addressing a research problem (Heavey, 2014). It is necessary to code collected data before analysis because coding aligns data with analysis objectives and selected analysis technique (Lester, 2013). Gender is one of the identified variables and 1 will represent male while 2 will represent

A Study On Zero Tolerance Policy

A Study On Zero Tolerance Policy There are hundreds if not thousands of students in any given school. The sheer size and magnitude of the student population encompassed in these schools leads to complications of school safety. Zero tolerance is a policy which was brought about enforcing school safety more firmly, and aimed to better protect students. However, the way in which these students are protected is highly debatable, making the zero tolerance ideology very controversial. Exactly which approach is most effective in protecting a student, let alone, thousands? Is strictness more effective than leniency? Overly strict policies aim to protect the majority, however, severally punish those who have to deal with the wrath of zero tolerance, those who violate the rules. Overly lenient policies can lead to dreadful events, however, give students a sense of reason, in turn creating an understanding of what they have done wrong. In the long run which method is most effective in protecting students? These type of questio ns, along with the excess amount of questionable cases, compose a highly controversial topic. The well being of a student is the single most important factor for public schools. No parent would ever send their child to school if there was a high probability of violence. For this reason there are people who favor zero tolerance. Domoine D. Rutledge, general counsel for the East Baton Rouge Parish School System in Louisiana, reports that zero tolerance policies have aided in creating a culture inside schools that certain things will not be tolerated, period. However, whether or not that policy is effective relies on how fairly its enforced and how consistently its enforced. He continues saying that: Schools districts have had to really balance the interest of the whole school, the student body, teachers and faculty . . . as well as the rights of individual bad actors. The ability to strike that balance, and to do it fairly, more than likely influences the effectiveness of the zero-tolerance policies. Whether or not zero tolerance is effective brings about more argumentative material. Statistical data reports a significant drop in school homicides following the 1999 school shooting at Columbine High School in Littleton, Colorado strongly suggesting, as Rutledge advocates, zero tolerance has in fact led to safer schools for students. (nces.ed.gov) Kay S. Hymowitz, a contributing editor for a magazine published by the conservative Manhattan Institute, stated that, The arrest of a pair of New Jersey 8-year-olds for pointing paper guns at classmates was just the kind of episode that leads people to question zero-tolerance policies. (Billitteri) Statements such as those insinuate a basis of anti-zero tolerance and further complicate the controversy. However it must be noted that, Its not so easy to distinguish the prankster from the wild-eyed adolescent with a [lethal] plan when lives are at stake, Hymowitz says. (Billitteri) How is one supposed to know the intentions of a giving situa tion? While the general consensus will no doubtingly agree that a pair of 8-year-olds pose little to no threat, on the slight chance of an event occurring, the questions of why werent they stopped or how could you assume will undeniably be asked, and in this sense, it is without a doubt better to assume the ugly and end up being wrong, than to assume no harm and end up with fatal consequences. Hymowitz continues, stating that, Zero tolerance may be more symptom than cure for the uneasy disciplinary climate of our schools. Certainly its no final answer to out-of-control 5-year-olds or revenge-crazed teenagers. But as the threats continue and the bombs and guns appear, its all weve got. (Billitteri) Bringing back the topic of effectiveness, those with the get-tough attitude witness no proof of zero tolerance policies creating a safer environment in schools. In fact, a decade of research on such policies by the American Psychological Association have concluded that zero tolerance can a ctually increase bad behavior and also lead to higher dropout rates. Schools are not any safer or more effective in disciplining children than before these zero-tolerance policies were implemented, the association said. (APA) There is much debate surrounding zero tolerance, however, the real problems arise when zero tolerance is set in motion. The question at hand to those who oppose zero tolerance falls into the legitimacy and fairness of punishment. In Newark, Delaware a 6 year old boy took a camping utensil which can be used as a knife, fork and spoon to school. Naturally anyone can safely assume there is no harm, however, Zachary Christie received 45 days in the districts reform school. (Urbina) In this case, the well being of the students surrounding Christie is thrown out of the window and it comes down to its consistency in being enforced. The boy clearly had no intention in causing harm, however, was treated as if he was. The only reason he was apprehended as a criminal was to set an example. Those who think to bring anything similar to school, be it a fork, a knife, or gun, will think back to Christie and decided not to. While this incident might seem like one of a kind, unfortunately, it is far from that. Zachary Christie is not alone, there are handfuls of cases which bring about much controversy over zero toler ance. During October of 1999 in Atlanta, Georgia a 15 year old South Cobb High School sophomore brought an unloaded gun to school. When school officials found the gun in his backpack he was immediately and permanently expelled from the school district. (Skiba 3) A sixth grader at Whitman Middle School in Seattle, Washington brought a squirt gun, painted black and brown to school during September of 1999. He was expelled after the gun fell out of his book bag during lunch. (Skiba 4) David Silverstein, a seventh grader in Glendale, Arizona, motivated by the film October Sky, brought a homemade rocket to school made out of a potato chip canister. Considered a weapon, school officials suspended him upon arrival. (Skiba 4) During May of 1999 in Pensacola, Florida a sophomore received a 10 day suspension and was threatened with expulsion after loaning her nail clippers to a friend temporarily. Quoted from the principal, Life goes on. You learn from your mistakes. We are recommending expul sion. (Skiba 4) On the morning of a late June day in 1998 two high school seniors in Pinellas County, Florida arrived to school and were immediately expelled. School officials were tipped off that the boys had skipped school and smoked marijuana with some friends. A federal appeals court ruled against the district, stating that the school had not even a scintilla of evidence that the two boys were under the influence at school. (Skiba 5) In February of 1999 in Ewing, New Jersey a freshman was accused of taking drugs and was asked to visit the school nurse to check his pulse and blood pressure. His suspicious behavior which forced this drug screen upon him was because he dozed off in his social studies class. The principal immediately suspended him after he refused to submit to a drug test. Eventually the boy was forced into taking a drug test as the principle declined to readmit him until he had done so. (Skiba 5) A sophomore at Westlake High School in February of 1999 was suspended for two full school weeks after he announced his French teacher was not fluent in the language during the schools morning announcements. School officials considered the comment as a verbal attack against the teacher in an attempt to justify their actions. (Skiba 6) These cases do nothing but illustrate the negative aspects of zero tolerance. However, one can see the argument for zero tolerance as any further actions were eliminated before they could occur. Even though, at what point are schools sending the wrong message, and ultimately, when will this wrong message be more detrimental to students? Another topic of discussion is the message zero tolerance sends to the students. Should the punishment fit the crime? Those in favor of zero tolerance tend to believe the only way to clarify right from wrong is to strictly enforce school policies, and consistently enforce them. While this without a doubt protects the students from possible threats, at the same time one can question whether or not this also sends a negative message. Punishing a student for a petty mistake with grave consequences instills fear among the student population and scares them into conformity. This is not a message students should be receiving. Treating those like Zachary Christie, to use as an example, can negatively affect their mental health. Its much more difficult for Christie to tell right from wrong, and in his mind, he has not done anything wrong, yet still received punishment. To Christie he got punished for nothing, which will affect his psychological wellbeing unconstructively. How will he learn f rom his mistake and how will he look at other things in life now that he has been severally punished for such a small and innocent act? He is 6 years old, he does not need to go through this. Another negative aspect of zero tolerance is that it hinders education. Students unnecessarily miss school to serve their punishment which also leads to future problems. Julia Steiny, a former member of the Providence School Board, reported that a kid [student] whos been suspended is statistically at high risk of dropping out of school. (Steiny) Supporting zero tolerance, Kay S. Hymowitz, a contributing editor for a magazine published by the conservative Manhattan Institute, wrote that Its not so easy to distinguish the prankster from the wild-eyed adolescent with a [lethal] plan when lives are at stake. (Billitteri) To school officials, the assumption of trusting a student who has made a mistake, or is joking around, is a much greater risk. One cannot truly know the intentions of a given situa tion, only can one assume what is going on. To those who are pro-zero tolerance, safety comes first, no matter how accomplished. Zero tolerance is a very intriguing topic simply because of the complexity behind it. Those in favor make incredibly compelling and persuasive arguments. However on the flip side, those who are against it make just as valid arguments. I believe there is too much information out there to be able to claim being on one extreme end of the spectrum, whether its for or against zero tolerance. While to some extent zero tolerance is effective, after going through the plethora amount of research, I ultimately believe zero tolerance is a hindrance and a negative aspect on school safety. Not ended, but rethought I believe zero tolerance needs to go through. While the core idea behind it, safety for every student, sounds great on paper, in practice, it has obviously failed. While there are not many, there are still several cases where small acts have led to obscene punishments, completely blown out of proportion. Another negative aspect of zero tolerance is that it sends the wrong message to stu dents. For these reasons, zero tolerance needs to end in public schools, and needs to be rethought.

Anorexia Nervosa and Bulimia Nervosa :: Causes of Anorexia, Bulimia Nervosa

What is an eating disorder? A simple definition of an eating disorder is abnormal patterns of behavior and thought. All eating disorders have shared characteristics. There is fear of becoming fat, drive to become thin, an obsession with food, weight, and calories. Families of sufferers also have an increased incidence of depression, obesity, substance abuse, and eating disorders. Two main eating disorders are Anorexia Nervosa and Bulimia Nervosa. Anorexia is an eating disorder in which a person is obsessed by thoughts of an unattainable image of â€Å"perfect† thinness. This occurs by starvation and/or excessive exercise and can result in death. Bulimia is an eating disorder involving the alternation between the extremes of eating large amounts of food in a short time, and then compensating for the added calories either by vomiting or other extreme actions to avoid gaining weight. There are other eating disorders other than Anorexia Nervosa and Bulimia Nervosa. Some include Food Avoidance Emotional Disorder (FAED), Food Refusal, Pervasive Refusal, Selective Eating, and Appetite Loss Secondary to Depression. Food Avoidance Emotional Disorder was first introduced by Higgs and colleagues in 1989. Sufferers of FAED have a history of food avoidance or difficulty. They also have a disorder of emotions. FAED patients have an absence of organic brain disease, psychosis, illicit drug abuse, or prescribed drug-related causes. Food Refusal is common in young children. "I'm all done." "Mommy, I don't want anymore." "No! I won't eat." These are all common phrases that a child of this problem might utter. These children often need to be bribed with threats of no dessert, or bribing them with their favorite foods. It is hard to distinguish between fads and eating disorders. Food refusers will eat their favorite foods with complete ease and also in certain situations such as a friend's house. Surprisingly these types of children are not underweight and not calorie conscious. This eating behavior is generally viewed as a behavioral problem that usually resolves itself in time. It does not represent a serious threat to the child's health or well being. Described by Lask, "Pervasive Refusal is a condition that is manifested by profound and pervasive refusal to eat, drink, walk, talk or engage in self-care. Children with this particular combination of symptoms do not fit any existing diagnostic category, and suggest that the condition may be understood as an extreme variation of the avoidance behavior seen in posttraumatic stress disorder.

Development of an Equation Essay

Purpose: Investigate a chemical reaction using lab procedures and observations. Then, find a pattern of reactivity and explain the findings using a chemical equation and particle diagram. Procedure: Refer to: Department of Chemistry, The Ohio State University. â€Å"Development of an Equation.† General Chemistry 1210 Laboratory Manual. Vol. 2013-2014. Plymouth: Hayden-McNeil. 32-35. Data/Results: Part A: In the potassium iodide solution, I think there were potassium atoms as well as iodine atoms. In the lead nitrate solution, I think there were lead and nitrate ions. The potassium atoms and the lead atoms can be classified as cations, since they are metals. The iodine atoms and the nitrate ion can be classified as anions since they are nonmetals. Upon mixing, the solution turned into a cloudy yellow color. Evidence that a chemical reaction occurred was that the two solutions created a new color because the two solutions were originally colorless. There was no gas formed. Part B: (Testing the Anions) Iodide reaction with hydrogen peroxide observations- The precipitate at the bottom turned into a red solid and the liquid solution was a dirty yellow color. Nitrate reaction with hydrogen peroxide observations- A colorless precipitate formed at the bottom and looked like a bubble. It was a relatively large bubble. The liquid solution was colorless and cloudy/fizzy. Since the reaction resulted in some fizzing and bubbles, this is indication that a gas was formed. (Testing the Cations) Potassium reaction with thioacetamide observations – No reaction occurred. Lead reaction with thioacetamide observations – A violet-black precipitate formed at the bottom of the test tube and the liquid solution was a cloudy grey color. It was about the same size precipitate as the nitrate reaction with hydrogen peroxide. Strong smell from the thioacetamide. Part C: Identification of ions in the precipitate that forms when lead nitrate solution is added to potassium iodide solution. (Testing for Anions) Reaction with hydrogen peroxide observations- A dark red precipitate formed at the bottom of the test tube and the liquid solution was colorless. There was not a large amount of precipitate formed and it sort of smeared along the inside of the test tube. Inferences: What anions are in the precipitate? -iodine (I-) When compared with results from part B to test anions, similar results were found. A dark red precipitate was formed in both. (Testing for cations) Reaction with hydrogen sulfide observations- A small, violet-black precipitate formed at the bottom of the test tube and the liquid solution was grey and cloudy. Inferences: What cations are in the precipitate? – lead (Pb2+) When compared with results from part B to test cations, similar results were found, A violet-black precipitate was formed in both tests. Exchange reaction- Positive potassium started off with negative iodine, and positive lead started off with negative nitrate. Potassium switched to combine with nitrate and lead switched to combine with iodine. Part D: Testing of Precipitate| Observations on Initial Precipitate Formed (relative amount, etc.)| Lead Nitrate: Potassium Iodide Ratio| Tube 1| Powdery, yellow precipitate formed at the bottom. Not very much precipitate. Little to no streaking. Clear liquid solution above precipitate. | 3:1| Tube 2| Powdery, yellow precipitate formed at the bottom. Equal to tube 1. Little to no streaking. Clear liquid solution above precipitate.| 2:1| Tube 3| Powdery, yellow precipitate formed at the bottom. A little more precipitate than tube 1 and 2. Little to no streaking. Clear liquid solution above precipitate.| 1:1| Tube 4| Powdery, yellow precipitate formed at the bottom. Much more than tube 3. Noticeable streaking of precipitate along sides of test tube. Clear liquid solution above precipitate.| 1:2| Tube 5| Powdery, yellow precipitate formed at the bottom. Most precipitate formed out of all test tubes. A lot of streaking of the precipitate along sides of the test tube. Clear liquid solution above precipitate. | 1:3| Testing of Supernatant| Observations| Inferences: Which ions were in the supernatant? List cations and anions.| Tube 1| The solution was clear with lead nitrate, but turned a yellow cloudy color with the potassium iodide. | Pb2+ (lead)-cationsNO3- (nitrate)-anions| Tube 2| The solution was clear with lead nitrate, but turned a yellow cloudy color with the potassium iodide.| Pb2+ (lead)-cationsNO3- (nitrate)-anions| Tube 3| The solution was clear with lead nitrate, but turned a yellow cloudy color with the potassium iodide.| Pb2+ (lead)-cationsNO3- (nitrate)-anions| Tube 4| The solution was clear with both the lead nitrate and the potassium iodide.| Pb2+ (lead)-cationsNO3- (nitrate)-anions| Tube 5| The solution was a little yellow with the lead nitrate, and a little less yellow with the potassium iodide.| K+ (potassium)I- (iodine)| Discussion/Conclusion: In part A, the first step was to obtain 5 drops of potassium iodine and 5 drops of lead nitrate and put them into a test tube and record observations. Then, to test the anions in part B, 5 drops of potassium iodine, 5 drops of nitric, 10 drops of dichloroethane, and 5 drops hydrogen peroxide to a new test tube. Then to a separate test tube, 5 drops of potassium nitrate, 5 drops of nitric acid, 10 drops of dichloroethane, and 5 hydrogen peroxide to a new test tube. Both should be stoppered and shook to produce two distinct layers. To test the cations, 2 test tubes would each get 20 drops of thioacetamide and 2 drops of nitric acid. One would get 5 drops of lead nitrate and the other 5 drops of potassium nitrite. Both test tubes were heated for 5 minutes and observations were recorded. In part C, the sample was used from part A and the test tube was centrifuged, then the clear aqueous layer was removed and discarded and the precipitate was washed with distilled w ater. This process was repeated once more. To test the anions, 5 drops of nitric acid, 10 drops of dichloroethane, and 5 drops of hydrogen peroxide were added to the solid precipitate and the test tube was stoppered and shook. These results were compared to the results from part B. To test for cations, the less colored aqueous layer was transferred to a clean test tube and the leftover layer was discarded. The solution was heated in a water bath until clear. 20 drops of thioacetamide were added, stirred then heated in a water bath and compared to the results from part B. In part D, to determine the ratio of  ions in the precipitate, 5 test tubes were labelled 1-5 and were filled according to table 3.1 on page 34 of the lab manual. The same medicine dropper was used for all drops and the test tubes were stoppered and shook, then centrifuged. The relative amounts and appearance of each precipitate were recorded. To test for potassium of iodide ions in the supernatant, 5 drops of lead nitrate were added to 5 separate test tubes with along with 5 drops from the appropriate test tube solution. The same was done to test for lead or nitrate ions, but potassium iodide was added instead. The perfect ratio for thi s lab was 2 potassium iodides for every lead nitrate. This ratio was found from balancing the equation and from comparing the results from part C to part B to match the observations of the precipitates. The ratio is the molar mass ratio of the balanced equation. The balanced equation was: 2KI(aq)+Pb(NO3)2(aq) 2KNO3(aq)+PbI2(s) and the formula of the precipitate was PbI2(s) based on the observations. In part B, the test for anions resulted in a dark red precipitate which was the iodide solution with hydrogen peroxide. In part C, the same results were found when lead nitrate and potassium iodide were added to hydrogen peroxide, therefore; the anions found were iodide ions because it has a negative 1 charge. In part B to test cations, the precipitate was a violet-black color for the lead solution reaction with thioacetamide. In part C, the same results were found when lead nitrate and potassium iodide were added to hydrogen sulfide. The cations found were lead ions since they have a positive 2 charge. Some inherent errors could have been while extracting the clear aqueous solution, some of the precipitate could have been extracted with the solution and transferred into another test tube. Upon heating, not all of the precipitate dissolved. Some of the drops with the micropipet varied also. The medicine dropper was more precise with the drops. Through this lab, a chemical reaction was used to find the pattern of reactivity which was an exchange reaction. This is known by finding the chemical equation and properly balancing it which is seen above. This lead to the ability to create a particle diagram and the findings of a perfect ratio of lead nitrate to potassium iodide.

Difference Between Two Population Means

Here, we describe estimation and hypothesis-testing procedures for the difference between two population means when the samples are dependent. In a case of two dependent samples, two data values—one for each sample—are collected from the same source (or element) and, hence, these are also called paired or matched samples. For example, we may want to make inferences about the mean weight loss for members of a health club after they have gone through an exercise program for a certain period of time.To do so, suppose we select a sample of 15 members of this health club and record their weights before and after the program. In this example, both sets of data are collected from the same 15 persons, once before and once after the program. Thus, although there are two samples, they contain the same 15 persons. This is an example of paired (or dependent or matched) samples. The procedures to make confidence intervals and test hypotheses in the case of paired samples are differe nt from the ones for independent samples.Two samples are said to be paired or matched samples when for each data value collected from one sample there is a corresponding data value collected from the second sample, and both these data values are collected from the same source. As another example of paired samples, suppose an agronomist wants to measure the effect of a new brand of fertilizer on the yield of potatoes. To do so, he selects 10 pieces of land and divides each piece into two portions. Then he randomly assigns one of the two portions from each piece of land to grow potatoes without using fertilizer (or using some other brand of fertilizer).The second portion from each piece of land is used to grow potatoes with the new brand of fertilizer. Thus, he will have 10 pairs of data values. Then, using the procedure to be discussed in this article, he will make inferences about the difference in the mean yields of potatoes with and without the new fertilizer. The question arises, why does the agronomist not choose 10 pieces of land on which to grow potatoes without using the new brand of fertilizer and another 10 pieces of land to grow potatoes by using the new brand of fertilizer?If he does so, the effect of the fertilizer might be confused with the effects due to soil differences at different locations. Thus, he will not be able to isolate the effect of the new brand of fertilizer on the yield of potatoes. Consequently, the results will not be reliable. By choosing 10 pieces of land and then dividing each of them into two portions, the researcher decreases the possibility that the difference in the productivities of different pieces of land affects the results.
