Issues in Information Systems Volume 13, Issue 1, pp. 225-231, 2012 IS THE GROWING USE OF ELECTRONIC DEVICES BENEFICIAL TO ACADEMIC PERFORMANCE? RESULTS FROM ARCHIVAL DATA AND A SURVEY Taylor S. Drain, Washburn University, taylor. [email  protected] edu Lakeisha E. Grier, Washburn University, lakeisha. [email  protected] edu Wenying Sun, Washburn University, nan. [email  protected] edu ABSTRACT In this study, we investigate the relationship between academic performance and the use of computer technology.We test our hypothesis which proposes that the growing use of electronic deveices is academically beneficial to high school students' standardized test scores and GPA. Our method of data collection includes both a survey of high school students in the Midwest area and an analysis of national SAT scores in the years before computing and in years with computing. Analysis of SAT archival data shows a negative correlation between scores pre -computing and scores post-computing (with computing influences), meaning that as scores before computing were decreasing, scores with prevalent computer technology are increasing.Our survey data also displayed a positive correlation between time spent on electronic devices for school purpose and GPA. Keywords: Computer Technology, Academic Performance , SAT, GPA, Electronic Devices INTRODUCTION The availability and use of electronic devices continues to grow. Over 420 million smart phones were sold worldwide in 2011 [6]. Almost 400 million computers were sold during 2010 , and that figure is expected to increase to over 1 billion units which will incl ude computers and smart phones by 2014 [3]. With the development of Wi-Fi hotspots, it is now easier for people to stay connected with their portable devices.Since electronic devices continue to be adapted to be friendlier to the end users, we want to research how the increased use of computer based technologies both in the classroom and at home impacts the academic performan ce of students. The following research question is posed: â€Å"Is the increased use of computer based technology improving the academic performance of students? † In order for us to investigate this question, we have analyzed two sources of data. The first being SAT test scores over the last 30 years. The second source is from data we collected from a survey that we presented to high school students.This study is important because it shows that the increasing use of electronic technologies for schoolwork is improving students’ academic performance. Computer technology is everywhere in the society, and most of the high school students in the U. S. own or have access to computer technology on a daily basis. We hope to show appropriate use of these technologies will increase learning. The remainder of the paper is organized as follows. We provide a literature review on related research. We then discuss the data analysis and present the results. The last section provides discussions of the results along with the implications of this study.LITERATURE REVIEW Our literature review suggests there are contradictory conclusions from various studies regarding whether computer use improves academic performance. Some studies state that computer use improves academic performance. Others propose that academic performance has nothing to do with computer use. A few studies suggest that computer use is a distraction to school studies and negatively impacts academic performance. 225 Issues in Information Systems Volume 13, Issue 1, pp. 225-231, 2012 One study claims that there exists evidence that Internet-time is harming children’s academic performance.This study was done by economists at the University of Munich named Thomas Fuchs and Ludger Woessmann who surveyed students in 31 countries. They created a very thorough, detailed survey in order to eliminate other possible causes of the downward trend of academic performance . They state in their results th at the â€Å"sheer ubiquity of information technology is getting in the way of learning† [7]. Another study hoped to find correlation in Internet/ Gaming Use and its numerous effects on adolescents. They analyzed not just academic performance, but social skills, relationship s, sense of reality and violent behavior.Their conclusion regarding internet use and its impact on academic performance was â€Å" although playing specific computer games has immediate positive effects on specific spatial, iconic, and attentional skills used b y the game, we need more research to see if long term computer and Internet use (both game and nongame) can lead to long term improvements in cognitive skills and academic achievement† [8]. Another study investigated the relationship between academic achievement and computer use. The focus was students in the 10th grade. They did a survey of three high schools in Ohio.This study had the students keep a log of how much time they used the comp uter for several different categories of activities. The study did not focus on any testing scores. Everything was measured against the students GPA. It did not find computer use at home and GPA to have a significant relationship [5]. A final study analyzed the impact of owning a computer at home and not necessar ily using it to assist in the classroom. They concluded that â€Å"home computers are associated with a 6-8 percentage point higher probability of graduating from high school† [2].They also discussed that their statistics supported the idea that owning a perso nal computer or having access to one at home had a positive correlation with grades and a negative correlation with suspension. While many studies, experiments and discussions continue to dwell around this topic, we will specifically analyze the impact of computer technology on high school students’ standardized test scores and determine if we can further support the idea that computing benefits learning . RESEARCH METHODOLOGY We gathered data from two sources. One was external and compiled from publicly reported standardized test scores.The second was collected from a survey of high school students we conducted. Our first data source is compiled ACT and SAT scores from their respective institutions statistical data archives. [1,4] We have access to ACT scores from 1994 to 2011 and SAT scores from 19 78 – 2011. SAT scores were not separated by state until 1998. We choose one state from each of the following regions to represent the United States: Midwest (Kansas), New England (Massachusetts), Southwest (Texas), Pacific Coast (California), Southeast (Florida), Mid -Atlantic (New York).We chose Kansas to represent the Midwest, as we knew our survey data would be gathered from that state. As for selecting representative states for the other regions, we took into consideration that we wanted the most general, unbiased data. Therefore we selected states with the largest population s in hopes that those who took the standardized tests would be a more thorough and accurate sample of that state. Prior to 2005, the SAT did not contain a writing section to the standardized assessment. In order to make our data comparable, we only compared the verbal and math scores for all the years we analyzed .We took the mean of the SAT, per year, per region (state), to the mean of the GPA that is recorded that year. For the ACT, we compared the scores for each year, for each region, to the national mean of that year and observed the trends present. We determined ACT data to be unusable for our study due to the fact that the year s and breakdown of the scores was very limited. Our second source of data is the responses from a survey that were distributed to high school students in the Midwest area. We took several steps to conduct this survey. First, we designed the survey instrument.This included several rounds of determining more refined questions and formatting for the best presentation. Our survey questions were divided into two categories. One category was general demographic information including: gender, age, and 226 Issues in Information Systems Volume 13, Issue 1, pp. 225-231, 2012 grade level. After looking at common survey questions, we were able to word these basic demographic questions to be clear and concise. The other category included data that would directly relate to our theory: GPA, SAT score, ACT score, time spent on computer for entertainment, school, and other purposes.In order to eliminate potential human error problems or difficulty reading participants' answers, we provided answers with checkboxes for every question except for the computer usage question. Our survey questions were divided into two categories. One category was general demographic information including: gender, age, and grade level. After looking at common survey questions, we were able to word these basic demographic questions to be clear and concise. The other cat egory included data that would directly relate to our theory: GPA, SAT score, ACT score, time spent on computer for entertainment, school, and other purposes.In order to eliminate potential human error problems or difficulty reading participants' answ ers, we provided answers with checkboxes for every question except for the computer usage question. Next, in order to survey students, we had to have our research project approved by our university's Institutional Review Board. This process included an extensive application requiring a description of potential participants, reason for research, research plan, survey instrument, and how the participation of students would be used.Shortly after submission, our application was approved, allowing us to rea ch out to local schools and begin our surveying. Third, we conducted a trial run of the survey by asking seven high schools students to take the survey and report any suggestions for improvement or problems comprehending the questions. F ourth, we distributed copies of the surveys to high schools in the area. We contacted principals to get their permission and delivered them to the schools that were willing to participate.The following pieces of data were collected: hours spent using an electronic devices on school days and non schools (for educational, entertainment or other purposes), SAT score, ACT score, GPA, age, gender and opinion of the effect of technology on their personal learning on a 7 point Likert Scale. Before analyzing the survey data, we prepared the data for analysis. We converted non-numerical data into a comparable numerical format. We declared 1 as representing Male and 2 representing Female. We used 1 – 7 to represent strongly disagree to strongly agree on the Likert scale.We assigne d numbers to the ranges of ACT and SAT scores starting at 1 for the lowest range and ending at 13 for ACT and 14 for SAT. For GPA, we assigned numbers for the ranges, 1 for less than 2. 0, 2 for 2. 0 – 2. 49, 3 for 2. 5 – 2. 99, 4 for 3. 0 – 3. 49 and 5 for 3. 5 – 4. 0. We then used SPSS to determine correlation between both GPA and standardized test scores and computer usage and GPA. We analyzed our data using a T -test For Equality of the Means to compare each region to the significant region of the Midwest. We consider this region to be significant because it is where our survey data is collected.The analysis of our survey data and SAT and ACT collected data is discussed in the next section. 227 Issues in Information Systems Volume 13, Issue 1, pp. 225-231, 2012 Figure 1. Survey RESULTS Archival Data We used the years 1972 – 1987 to represent prior to popular computer use and the years 199 5 – 2010 to represent the emergence of computer technology and increased use of it for educational or other purposes. Using SPSS, we found significant negative relationships between these time periods with both Spearman’s and Pearson’s correla tion tests. The Spearman test between these two 15 year periods of scores was -. 59 and (p-value = 0. 01). The Pearson test between these time periods was -. 764 (p-value = 0. 01). We graphed the Combined Verbal and Math scores for both the pre-computing time period (1972 – 1987) and for the with-computing time period (1995 – 2010). Figure 1 below shows the National SAT score trend for a fifteen year period before computing was prevalent among high school st udents (1972 – 1987). The data illustrates a negative trend for this time period. Figure 2 below shows the National SAT score trend for the fifteen year period 228 Issues in Information Systems Volume 13, Issue 1, pp. 25-231, 2012 with computing among high school students (1995 – 2010). The data for this time period illustrates an initial upward trend for the first ten years. Figure 2. National SAT scores from 1972-1987 Figure 3. National SAT scores from 1995-2010 Survey Data 102 complete surveys were returned and the demographics of the respondents are shown in Table 1. The sample population had slightly more males (52%) than females (48%). The sample population had various ages including 12 years (1%), 14 years (14. 7%), 15 years (26. 5%), 16 years (20. 6%), 18 years (21. 6%), and 19 years (1%).We had students from four grades; 9th had 33 (32. 45), 10th had 29 (28. 4%), 11th had 10 (9. 8%), and 12th had 31 (30. 4%). Students spent an average of 5. 36 hours using computer technology on school days and 8. 45 hours on non -school days. 229 Issues in Information Systems Volume 13, Issue 1, pp. 225-231, 2012 Gender Female Male Grade 9th 10th 11th 12th Table 1.

Several significant relationships were evident in our survey data. All of the results listed below use Spearman’s correlation test between two variables. We had a . 223 positive correlation between reported GPA and Computer Use for School on School Days (p-value = . 05). There was a . 213 positive correlation between GPA and Computer Use for Other on School Days (p-value = . 05).No significant correlation was found between computer use for school on Non-School Days and GPA, due to the fact that the majority of our respondents reported that they did not spend any hours on schoolwork on Non-School Days. We found a . 663 positive correlation between GPA and ACT scores (p-value = . 01). We also found a positive correlation of . 224 between GPA and sex. Finally, we found a . 241 positive correlation between students that felt that computer use was beneficial to their personal academic performance and those that utilized technology for school purposes had a p-value of . 5. Table 2 summarizes these correlations and highlights the significant correlations.

We also surveyed local high school students asking for computer usage in hours, standardized test scores and GPA. The analysis of SAT scores reveals an evident negative correlation.This significant correlation illustrates that in the first time period, 1972 – 1987, SAT scores were decreasing, but that in the years with computing, 1995 – 2010, scores were increasing. It can be inferred, without regarding other external factors, that computing has benefite d student performance in standardized testing, specifically the SAT. A thorough comparative analysis of our survey data indicates several significant correlations. First, the positive relationship between the hours of computer use for school purposes and GPA demonstrates the idea that use of electronic devices for school urposes benefits academic performance. Second, those with high GPA's also had high standardized test scores, such that it can be inferred that appropriate use of electronic devices also benefits students 230 Issues in Information Systems Volume 13, Issue 1, pp. 225-231, 2012 in their standardized testing. Finally, students who had the opinion that use of electronic devices improved their personal academic performance utilized those tools, which are shown by the significant correlation between students who held this opinion and used electronic devices for schoolwork.These significant correlat ions imply, in our sample, that use of computing, or electronic devices for school work and the like, benefit students in both their GPAs and their standardized test scores. Our survey results and standardized test score analysis show an improvement in academic performance with increased computer usage. Specifically, our results show that students who spent more time using their electronic devices for school purposes did better in school than those who claimed they used their devices for other purposes.This result in our survey sample group illustrates o ur theory that â€Å"intelligent use† of electronic devices improves academic performance of students. LIMITATIONS AND FUTURE RESEARCH This study has a few limitations. First, in our analysis of standardized test scores, we decided against including the Writing section of the ACT as it made comparing scores between previous to 2005 and after 2005 inaccurate. This limited our ability to determine the improvement of devolvement of writing skills based upon increase in computer usage.Also, in our analysis of standardized test scores we did not include ACT scores in our results section because there was a very narrow amount of data available before prevalent computer use. Finally, we only surveyed students in local area high schools. In order to make a more accurate and generalized conclusion, we would need to have a further reaching and larger sur vey size. Further research must be conducted in order to determine if our results could be duplicated in another sample group and to rule out external factors.

My Big Fat Greek Wedding Essay

â€Å"My Big Fat Greek Wedding† is a romantic comedy that explores cultural differences in a combination of romance and humor. The story revolves around Toula, a thirty-year-old Greek American single woman, who lives with her family in the suburb of Chicago. She works in her family’s business, a restaurant called â€Å"Dancing Zorba’s.† Toula is expected to marry from their ethnic background. However, she struggles with her strict father to convince him that she longs for something else in life. She enrolls in college and takes computer classes. She manages her aunt’s travel agency and starts dating Ian Miller, a white high school English teacher. They date secretly for a while, before she has the courage to introduce him to her family. Her father is angry over her dating a non-Greek. The overall of the story occurs when both sides try to adjust to each other. This movie relates a lot to the five themes of geography we have been studying. It relates to location because they live in the suburbs in Chicago, which is a place. A location is people and places are positioned variously on the Earth’s surface. Also, the father lived in Greece before coming over to the U.S. So therefore, location relates to this movie. It also relates to place, physical and human characteristics distinguish one place from other places. In Greece, you have a very religion type of country. Houses are made to represent the Parthenon, which to the Greeks, is the home of Athena. Rather in, Chicago, you have very modern houses that don’t symbolize really anything. It relates to relationships within places also because in the movie, the family’s house in Chicago resembles the Parthenon, which you wouldn’t exactly see in such a city. It can also relate to movement because the family is constantly on the phone with each other. With Greeks, you would normally have a huge family, so they are constantly talking on cell phones or driving to each other’s houses to gossip. Also, last but not least, it can relate to region. The Earth can be divided into regions to help us understand similarities and differences of people and places. For example, Greece and Chicago are divided because they are very two different places. I really enjoyed watching this movie in class. It was very humorous and I learned a lot. Before watching this movie, I didn’t know that when you marry, your job as a woman is to basically cook, clean, and have kids. That shocked me completely. I loved the movie, however it was very predictable. By the way they set up the movie, you could easily tell what was going to happen next. But the overall movie was great. I would definitely recommend this movie to my friends to watch, it’s a very good movie if you just want to have a good laugh.

Criminological Theory Assignment Example | Topics and Well Written Essays - 1750 words

Criminological Theory - Assignment Example Many theorists have contributed by presenting theories linking crime to the fields of biology, psychology and sociology. The basic tenets of the biological, psychological, and sociological perspectives for explaining crime will be identified and discussed here. In the 19th century, Cesare Lombroso gave biological description of crime. Lombroso gave significance to criminals instead of crime (Beccalossi, 2010). Lombroso attached ape like characteristics to criminals. According to his theory, criminals were born criminals and contained facial and bodily features alike to apes. The criminals were considered to have big jawbones, high cheekbones, longer arms, larger ears, extra hand fingers and toe fingers, and much more (Gibson, 2002). According to Lombroso, criminals were â€Å"vain, vindictive, lazy, dominated by a thirst for blood, and delighting in orgies† (Beccalossi, 2010, p. 564). Lombroso criminal personalities were savage and contained animalistic physical features. He connected criminality as something that one obtained by birth. He gave specific consideration towards genetically characterized appearances of people and rejected any social happening linked with criminality of criminals (Gibson, 2002). After Lombroso, Charles Goring presented his theory of genetic criminology, but unlike Lombroso, he did not specified bodily features of criminals. According to Goring, criminals showed criminal behavior because of having low IQ (Rafter, 2008). Goring also explained criminals as having deviated towards criminality by birth. William Sheldon, another biological theorist, described different bodily appearances as descriptive of criminal associations. Humans, according to Sheldon, were to be divided in three types of bodies were ectomorphs, endomorphs and mesomorphs (Rafter, 2008). Out of these three types, only mesomorphs were the one who were deviated towards crime. They had intimidating appearances like muscular bodies and strong figures

Switching from Insulin to Oral Sulfonylureas in Patients with Diabetes Lab Report

Switching from Insulin to Oral Sulfonylureas in Patients with Diabetes Due to Kir6.2 Mutations - Lab Report Example Diabetic patients have a KATP channels with decreased sensitivity to ATP inhibition because of KCNJ11 mutations. As a result of this, their channels remain open in the presence of glucose, thereby reducing insulin secretion. Ketoacidosis or marked hyperglycemia is seen in such patients with low levels of circulating endogenous insulin and are therefore treated with insulin. A class of drugs called Sulfonylureas, close KATP channels by an ATP-independent route, thereby causing insulin secretion. The authors hypothesized that sulfonylureas may represent a suitable therapy for patients with KCNJ11 mutations. The purpose of the study was to assess i) glycemic control in 49 consecutive patients with Kir6.2 mutations who received appropriate doses of sulfonylureas ii) to investigate the insulin secretory responses to intravenous and oral glucose, a mixed meal, and glucagons in smaller groups and iii) to assay the response of mutant KATP channels to the sulfonylurea tolbutamide in xenopus oocytes. A total of 49 consecutive patients from 40 families were identified as having diabetes caused by a heterozygous KCNJ11 mutation through sequencing performed in molecular genetics laboratories in Exeter, United Kingdom (34 patients), Paris (5 patients),and Bergen, Norway (10 patients) were the study participants. All 49 patients either switched from insulin to sulfonylurea therapy or were unable to switch but received an adequate dose of sulfonylureas before October 2005 were included in the study. No other selection criteria were applied. No exclusion criteria were defined by the authors and the study did not include randomization technique. As it was a cohort study, it was not possible to compare the groups. Patients with a successful switch (n =44) had the following mutations F35V, H46Y, R50Q, G53N, G53R, V59M (6 patients), K170T, R201C (5 patients), R201H (23 patients), R201L, E322K, Y330S,

Will GM's Strategic Plan Lead to Future Success Case Study

Will GM's Strategic Plan Lead to Future Success - Case Study Example The third strategy that GM has implemented is the premium pricing strategy that has led to higher margins and prices thus ultimately leading to higher profits per unit sales. GM has cut the incentives for the dealers in order to attain higher margins. The fourth strategy linking the executive compensation to company performance through ensuring the executive bonuses are dependent on the margins posted by the company. The company has also carried out staff rationalization in order to reduce the boated wage bill. Based on the case study, GM’s vision is to become the most profitable automaker in the world. The company is not interested in expanding its market share, but its strategies aim at reducing the operating costs and increasing the unit margins in order to improve the profitability of the company (Daft 183). The vision is realistic since it managed to regain from Toyota as the largest automaker in term of sales figures and has increased its profit margins. The company has also controlled costs. In this case, higher margins and sales volumes will make GM the most profitable automaker if the measures implemented in controlling costs are successful. The first SMART goal is to raise profit margins by 10 percent. This goal is specific and measureable since the current profit margin is 6 percent and this could go up to 10 percent after restructuring the company and improving operational efficiency. The reduction in engineering and manufacturing costs through downsizing the auto platforms will significantly reduce the manufacturing costs. Use of standardized plants and assembling will also improve efficiency of operations and lower costs. Other companies that have few auto platforms have managed to attain a return of 10 percent of sales and this goal is realistic and time-bound since GM will have only 14 auto ‘platforms’ by 2018. The second SMART goal of GM is to make more than $ 10

Coursework - Case Study Example In this context, the employer can be prosecuted if the worker died or he or she is an illegal immigrant. An example of a case of Donoghue v Stevenson (1932) HL, Mrs. Donoghue accompanied by a friend went to Minchella’s Wellmeadow. The friend ordered ice cream and a bottle of ginger beer, when all the beer was poured, and it was found to contain a snail. Mrs. Donoghue became unwell after consuming the contaminated beer. The owner of the cafà © was held negligible of duty of care, because the neighbor was injured. The cafà © owner act affected another person that she ought to have them under observation not to be affected. Where a person is held in an institution then the organization owes the convict a relevant duty of care. It applies where the offence committed has features relating to offence in section occurred before 1 September 2011, and then the common law applies. The court will decide whether the organization owed the dead a duty of care (section 2(5) (Ormerod, Smith & Hogan, 2011). However, in order to conclude there was a breach, it must be very serious and the extent of risk to death it posed section 8(2). This shows the complexity of the legal nature to the presence of a duty of care in the law of negligence. A case of Khan, R v [1993] CA, the defendant, a drug dealer gave heroin to a 15-year-old girl. Afterward, the girl was in apparent need for medical attention but the defendant left her until the following day when she was found dead. The drug dealer was convicted for the offence of omission to ask for medical assistance and not giving heroin. The jury concluded that he owed the girl duty of care, which he breached, and constituted gross negligence and thus a criminal act. Even though the Act does not define causation, the intention follows the features of the law on gross negligence manslaughter. Therefore, the hearing will need to demonstrate that the breach was more than the

Article Review - Essay Example Moreover, the limited funding usually available to managers of non-profits make them focus on only high-priority tasks, sacrificing quality of management. Hence, there is an inherent trade-off between management efficiency and leadership quality. Most non-profits seem to have one or the other; but the most successful few are those that display both these characteristics. Most leaders of non-profits surveyed for the article do indeed recognize this trade-off and admit to short-comings in their management standards. In their willingness to improve the same, these leaders were open to learning new techniques and principles and adopting them to their organizations. Some of them have already implemented some of principles and tasted success. The first of such measures is Getting Strategic Clarity. Achieving strategic clarity â€Å"means answering, in very concrete terms, two questions that are core to a nonprofit’s mission: What impact are we prepared to be held accountable for? A nd â€Å"What do we need to do - and not do - in order to achieve this impact?† (Stid & Bradach, 2009, p.37) By answering this set of questions, leaders are in a better position to align their resources and processes around core objectives.

Standardised housing was implemented in the 1960s, and these regulations included specifications for density, public space, services, etc. Ballymun's high rise towers were the result of experimentations at this time. However, "the classic pattern that has occurred again is that a development pattern has evolved of rapid creation of new residential communities without adequate infrastructure or facilities" (Williams and Shiels, 2001, p. 27). Previous plans to regenerate Dublin included the Integrated Area Plans (Kelly, 2005) and the Urban Renewal Act of 1986 (Suzanne, N. 2001) that came about as a result of the unwillingness of the private sector to enter many Dublin inner city neighbourhoods that had degenerated to dereliction. The government offered tax incentives to attract private business. This was successful in combating the decay of the Dublin cities, but those urban renewal schemes were only questionably effective in some cities. Because of the profit motive, architectural and design concerns were of little value to the investors. In addition, the economic benefits of the investment were mostly unavailable to the residents of those towns. This led to the newest Urban Regeneration Projects (2001). According to the Egan Review and other organisations, regeneration involves the search for long term restoration and renovation of neighbourhoods, improvement of transportation systems, and involves an outlook of encouraging social inclusion and economic stability. These objectives are to be realised concomitant with ones of sustainable use of natural resources, such as energy and water. These objectives have necessitated the support of sound local leadership as well as concurrence among local, regional, and national policies (Carley, et al., 2005). Brief History of Ballymun The Ballymun population stands at approximately 20,000 and 44.6% of these persons are unemployed. It has even been suggested by some authorities that the true unemployment figure might lie in or above the 60% mark. One third of the population is below the age of 14, and over a third of the households are run by a single parent, while the national average is 10%. The percentage of children who attain a school-leaving certificate is only 7% (Environmental Appraisal, p. 43). Before the Regeneration project, the city of Ballymun suffered from several structural, social, and economic problems. Many blocks of high-rise buildings were located in the city, and these were poorly constructed, having internal structural flaws as well as the disadvantage of being poor conservers of energy. This led to wide-scale removal by tenants, high levels of vacancies in apartment buildings, unemployment and drug problems. Voting turnout for local government elections has been as low as 15% (de Rossa, 1998). Social exclusion was also a significant problem in Ballymun that resulted from its spatially isolated location, as it was cut off because of poor links in transportation (Muir, 2003). Ballymun Regeneration Ltd. took up the challenge and with the help of other environmental agencies, constructed an energy and environmental strategy

Alcoa Inc Essay Example | Topics and Well Written Essays - 2500 words

Alcoa Inc - Essay Example It has a large product base – most of them are considered as most sustainable products. Serving different markets ranging from Aerospace to consumer packaging industry, Alcoa, over the period of time has been able to generate strong growth rates. Further it is also being continuously expanding into various markets and currently most of its revenue growth is coming from China. Based on the projections of the China’s future economic performance and strong demand being generated from that region, it is largely believed that the future performance of the company would largely depend upon how the Chinese economy performs. This is also because of the fact that the growth in North American markets for the company has been negative and considering the recent credit crunch in the market, it is largely anticipated that the demand from the traditional region of business for Alcoa would decrease substantially and company has to rely on the other markets to develop. Alcoa is the leading producer of primary aluminum, fabricated aluminum as alumina facilities and is also an active player in other aspects of the industry also. It products are served in markets like Aerospace, Alumina, Aluminum Ingot, Automotive, Building and construction, commercial transportation, Industrial Products and services as well as packaging and other consumer products. â€Å"In addition to aluminum products and components including flat-rolled products, hard alloy extrusions, and forgings, Alcoa also markets Alcoa ® wheels, fastening systems, precision and investment castings, and building systems† (Alcoa, 2008). The company has a presence in almost 34 countries with 97000 employees working for the company in various positions in various countries. It has been the honor of the company that it has been labeled as most sustainable company in the world in World Economic Forum, Davos, Switzerland. The company has a record of working on creating an environment which is often considered as safer

Assignment 7(675) Essay Example | Topics and Well Written Essays - 750 words

Assignment 7(675) - Essay Example I suggest so because it is often healthier initially for an employee to evaluate and rectify himself based on what he believes he lacks, rather than giving an outright harsh list of complaints from students or supervisors like myself at the first stage. Therefore, my overall plan to help Mr. Smith is to get him to work on his self-assessment, followed by some feedback from students and fellow teachers, then formulating a plan to help overcome his shortcomings as an institutional performer. The central idea will be to identify and work on his strengths and weaknesses and to assess what more can be done to improve his performance. Step 1: Initiate self-assessment using instruments and inventories. For giving this process a push, I would arrange an informal meeting with Mr. Smith after school. In this meeting, I would outline with his help, the purpose of this activity and what we hope to achieve by the end of it. Next, I would hand over to him some documents which include his past appraisals and remarks of the principal, myself, the curriculum director and the students. These will give him an idea as to what to consider. Having prepared a list of skills and competencies required and expected of in our school from our teachers, I would ask Mr. Smith to assess the list and use it to perform his self-assessment. All the above inventory will act as a criteria for the self-assessment. Asking him to go home and work on the task handed to him, I would arrange a next meeting of a similar fashion with him after a few days. Before the completion of Mr. Smith’s task, I will need to gather some idea as to how well Mr. Smith is at his job by asking the students and his fellow colleagues. This can be done either on a one on one basis or by questionnaires handed out. This step will come in handy at a later stage. Step 2: Perception of self:Â   How accurate? An individual’s perception of oneself involves their knowledge of the

Kanoa K. Essay Example for Free

Kanoa K. Essay Kanoa K. is by far one of the most unforgettable characters of my life. He is not only my boyfriend, he is my best friend, someone I know would help me through difficult times, and someone who has helped me through tough times. If Kanoa were a fictional character, it would be very difficult to determine whether he is a believable character. He is one of the most perfect and awesome people I know, making him unbelievable. Kanoa is always helping his friends and me; he has a kind heart and is a good person, which is something I only truly find in a few individuals. Another thing that makes Kanoa an unbelievable character is his uniqueness. He is not your ordinary boy, Kanoa is masculine yet sensitive; he knows himself very well and is different from most. Kanoa is a â€Å"skater† but isn’t a jerk, punk or fool, I believe that this is because he knows what he is and what he’s not, he doesn’t let stereotypes get to him. It is not typical for a sixteen-year-old to know himself or herself so well. Some things make Kanoa Kruse a very believable character. He is a deep, complex individual who has hopes and dreams just as everyone else does. He has a direction in life; an idea of what he wants to do with his future, a notion of what he wants his lifetime occupation to be. Because Kanoa is a human being, he does make mistakes. Whenever Kanoa makes a mistake, he learns and grows from the experience. Kanoa has changed over the years, as anyone does. At first, he started of as a person I passed by in the hallways. The first day I saw him, I was eleven. I didn’t know who he was, not even his name, the only thing I can remember thinking was, â€Å"oh, he’s cute†. He was 13, an eighth grader. Since I was a sixth grader, the â€Å"lowest class†, I didn’t make a single effort to know him; he was just a pretty face. A year passed and I made some new friends, one of my friends was a fair-haired, English boy named Jacob. Jacob and I began to talk a lot; one reoccurring topic of our conversation was Kanoa. Jacob told me that I would get along really well with Kanoa; the three of use should hang out sometime. I didn’t remember whom Jacob was talking about, I only knew Kanoa by face and not by name. Kanoa and I did not get to meet each other that year. In December 2007, I cut out my horoscope for that month out of a fashion magazine. My horoscope stated that on the twenty-sixth of this month, one of my close friends would try to hook me up with one of their friends. At the time, I just rolled my eyes and tacked the clipping to my corkboard, I didn’t believe, even in my wildest dreams that this horoscope would come true. On December 26, I woke up to the buzzing of my cellphone, it was my close friend Jacob, He told me that his friend Kanoa wanted to be â€Å"hooked up† with me. Jacob had been telling Kanoa about me and Kanoa wanted to give things a chance and see how they end up, I decided to accept his offer and get to know him. Since then, Kanoa and I have been dating. At first, he started of as a pretty face, then he became a friend of a friend and now he is one of the most important people to me, I know he will always be here for me when I need him.

Renal Excretion of Paracetamol | Experiment

Renal Excretion of Paracetamol | Experiment Paracetamol, known as acetaminophen in the USA, is one of the most commonly used analgesic and antipyretic drugs available over-the-counter. Its common name derives from the full chemical name: para-acetyl-amino-phenol, with the chemical formula C8H9NO2Â  and a molecular weight of 151.17. Paracetamol does not have any significant anti-inflammatory action and therefore cannot be accurately described as a non-steroidal anti-inflammatory drug (NSAID), as was once thought. Its mechanism of action is still poorly understood but some studies have suggested that it inhibits a variant of the cyclo-oxygenase enzyme COX-1, which has been designated COX-3 (Swierkosz et al., 2002). Paracetamol acts mainly in the central nervous system and endothelial cells, rather than in platelets and immune cells. Boutaud and colleagues (2002) hypothesised that this may be explained by the high levels of peroxides found in the latter cell types, which inhibit the action of paracetamol. There has been some debate on the subject, with other researchers proposing an inhibitory action against COX-2 (Graham Scott, 2005). Further research is required to fully elucidate the mechanism of action at the molecular level. Following oral administration and absorption from the gastrointestinal tract, paracetamol enters the blood and is distributed throughout the body. It is metabolised by enzymes in the hepatocytes of the liver and the majority is converted to inactive metabolites by conjugation with sulphate or glucuronide. This is then filtered out of the blood by the kidneys and into the urine, via active renal tubular secretion. A small portion of paracetamol remains unaltered and passes into the urine via glomerular filtration and passive absorption (Morris Levy, 1984). There is also a small proportion of the paracetamol that is metabolised by the cytochrome P450 system, which results in the formation of cysteine or glutathione conjugates and mercapturic acid conjugates. These products of oxidative metabolism are also excreted renally (Andrews et al. 1976). Paracetamol has a low therapeutic index, so the therapeutic dose is very close to the toxic dose. Toxicity can occur following a single large dose (>10g) or with chronic lower doses (4-5g/d) and is usually seen as hepatotoxicity, which can result in death within several days (Wikipedia). Toxicity occurs when the enzymes responsible for catalysing sulphate and glucuronide conjugation become saturated, forcing metabolism to be increasingly dependent upon the cytochrome P450 system. This results in formation of a toxic metabolite, N-acetyl-p-benzo-quinone imine (NAPQI), which is normally mopped up by binding to the sulphydryl group of glutathione to form inactive conjugates and mercapturic acid. Toxicity occurs when the glutathione supply becomes exhausted and NAPQI binds indiscriminately to molecules within the cell, such as membranes, to cause cell damage and death, seen as acute hepatic necrosis. Major pathway for normal metabolism Minor pathway via cytochrome P450 system produces toxic metabolite (NAPQI), shown in red. Normally this is detoxified by binding to glutathione. Toxicity occurs when pathways 1 and 2 are overloaded and NAPQI binds to molecules of the cell, causing damage. Modified from Rang et al. 1995. The aim of this experiment is to investigate the renal excretion of paracetamol, by measuring the levels of paracetamol metabolites in human urine over 6 hours following an oral dose of 500mg. The total excretion will be assessed using the spectrophotometric method. From this data the elimination rate constant (KE) and the half-life (T1/2) will be calculated. Qualitative analysis of the various metabolites will be conducted using appropriate chemical identification techniques. METHOD A standard stock solution of paracetamol was prepared at 1mg/cm3 and dilutions were made to give a range of known concentrations. 1 cm3 of the paracetamol solution was added to 1 cm3 blank urine and 4 cm3 4M HCl, and mixed thoroughly. A blank duplicate was also prepared, using water instead of urine. After an hour in a boiling water bath the tubes were cooled and water added, up to 10 cm3. 1 cm3 of this hydrolysed urine solution was added to 10 cm3of colour forming solution, mixed and allowed to stand for 40 minutes. The absorbance of each solution was measured, using the spectrophotometer, zeroing the instrument using the drug free urine sample in between solutions. This produced the readings for the calibration curve. The collected timed urine samples were then processed in the same way, adding 1 cm3 water instead of paracetamol solution. RESULTS AND DISCUSSION Known concentrations of paracetamol underwent spectrophotometry to measure the absorbance at 620nm. These results were used to produce a calibration curve (figure 3). The timed urine samples were then analysed following the same protocol and the absorbance at 620nm was used, in conjunction with the calibration curve to ascertain the concentration of paracetamol in the urine. Unfortunately, half of the samples produced absorbances outside the range of the calibration curve. Because this curve is non-linear, extrapolation and dilution cannot be used to accurately deduce the concentration of paracetamol in the urine. For the purposes of this report the concentration for these samples has been declared as ‘greater than 800ug/cm3’. This is not very satisfactory and further experiments must be done to extend the range of the calibration curve to the maximum absorbancy of the timed samples. The values of KE and T1/2 have been calculated to demonstrate the procedure, but are ina ccurate and will need revising once accurate concentrations have been established form the calibration curve. Table 1: Timed urine sample Mean absorbance 620nm Conc. ug/cm3 Vol. Urine (ml) Total drug (ug of paracetamol) Excretion rate mg/h 0 0 0 0 0 0 1 hour 0.256 192 245 47040 47 2 hours 1.918 >800 50 40000 40 3 hours 1.769 >800 38 30400 30.4 4 hours 1.028 >800 55 44000 44 5 hours 0.349 246 135 33210 33.2 6 hours 0.255 192 160 30720 30.7 Table 1 contains the absorbance results of the timed urine samples and the deduced concentration of paracetamol in the urine, as well as the hourly excretion rate. The total amount of paracetamol excreted over the 6 hour period was 225.3mg, which is 45% of the orally administered dose. Due to problems discussed above, this is an underestimate of the true percentage of dose excreted renally, which has been found to be 55-70% by other studies (Steventon et al., 1996). When log of the excretion rate (equivalent to total drug excreted per hour) is plotted against time, a linear plot should be achieved, from which KE can be estimated. This is shown in Figure 4, but is likely to need revising. The slope of this straight line equates to : KE /2.303, which gives a value for KE of 0.094. Using the formula: T1/2 =0.692/ KE , the value of T1/2 = 7.36 hours. This states that it takes the body 7.36 hours to excrete half of the drug administered. This is longer than the 1-4 hours usually quoted for paracetamol (Rang et al. 1995), and is not surprising given the underestimation of the paracetamol urine concentration. With proper calibration, this would be expected to decrease to nearer the previously found results. There were no results for the qualitative studies for metabolite composition, but it would be expected that sulphate and glucuronide conjugates would constitute the majority of the sample, with a smaller quantity of unchanged paracetamol, cysteine/glutathione and mercapturic acid metabolites. These results only represent one individual on one day and replications of this experiment are crucial. Nutritional status, recent alcohol consumption, ethnic background, concurrent drug usage and illness must all be taken into account as factors that may affect paracetamol metabolism and excretion (Riordan Williams, 2002, Patel Tang, 1992). Further analysis of paracetamol excretion Hepatotoxicity and drug interactions Table 2 shows how concurrent use of phenobarbital, an anti-epileptic drug, can increase the severity of liver damage caused by paracetamol administration and its subsequent metabolism. Table 2: Effect of Phenobarbital on paracetamol induced hepatotoxicity Treatment Dose of Paracetamol (mg/kg) Severity of liver necrosis None3751-2+ Phenobarbital3752-4+_________ This occurs due to metabolism of phenobarbital by enzymes of the P450 cytochrome system, which results in upregulation of their production. As explained in the introduction (see fig. 2), P450 enzymes also metabolise paracetamol, to form the toxic metabolite NAPQI. This is normally a minor pathway but as the amount of P450 enzymes available increases, the activity of this pathway also increases. This results in a larger than normal amount of NAPQI, which is mopped up and inactivated by glutathione. Glutathione supplies will eventually run out, which occurs sooner if the person is malnourished. When this happens the toxic metabolite binds to cell components, causing necrosis. To prevent this occurring, such as in cases of overdose, N-acetylcysteine can be given (Routledge et al., 1998), which is required for glutathione synthesis and helps to boost it. This allows a greater amount of the toxic metabolite to be mopped up and reduces cell damage. Paracetamol metabolism following hepatotoxicity Table 3: Plasma paracetamol concentrations (ug/cm3) PatientsPlasma paracetamol4 hrs after12hrs after Half life (h)ingestioningestion _______________________________________________________________ no liver damage (18)2.9 +/= 0.3163 +/=20 29.5 +/=6 liver damage (23) 7.2+/= 0.7296 +/= 26 124 +/=22___ Table 3 shows that, in a study, the ability of patients with liver damage to eliminate paracetamol from the blood is much decreased, compared to healthy people. This is seen by the prolonged half-life and the high levels of paracetamol in the plasma. The plasma level does come down by 12 hrs, which indicates that there is enough functional liver reserve to metabolise some of the drug, but the level is still very high. To ascertain whether it is just conjugation that is affected, or whether all the pathways are affected equally it would be necessary to quantify the levels of different metabolites in the blood and urine. As conjugation is responsible for the majority of metabolism, damage to all systems will still show up as affecting conjugation the most. In theory reduced clearance of a substance is useful for monitoring the severity of liver damage, but in the case of paracetamol it would be unwise as it could potentiate the hepatotoxic effects and worsen the liver condition. It is also unnecessary as there are already a number of reliable blood tests for liver function and damage. REFERENCES Andrews, R. S., Bond, C. C., Burnett, J., Saunders, A.

Economic Comparison: Australia and Malawi

Economic Comparison: Australia and Malawi Definition of output levels The amount of goods or services in a given period of time produced by an industry, country or film in the economy we can call it as output levels, whether used or consumed for the production. The national output’ concept in the field of macroeconomics is absolutely necessary. This is not a huge amount of money, but to make a country rich is the national output. Australia Agriculture Australias economy is mainly dominated by agriculture. Australia is the major producer and exporter of agricultural products. Australian agricultural map represents a different area of different crops grown in Australia. It is clearly shown in Figure 1 below. Australia more than four hundred thousand people are involved in the agriculture or the jobs which is related to the agriculture. Australian agriculture increased by about 3% of Australias gross domestic production. Australian agriculture contributed about 80% of export earnings until the 1950s. In spite of the record has declined in recent years because of the economic expansion. Australian agriculture contains extensive variety of crops, dairy, cultivation, viticulture, animal husbandry and fisheries. Australias agricultural takes after reasonable exchange methods and is a part of agricultural trading nations, Cairns Group. Australias agricultural industries have been very low subsidiaries or support from the government, but t hey are stretched out amid uncommon circumstances like dry seasons, saltiness or acridity of soils, and so on. Australias primary agricultural products are utilized for export and domestic utilization. Terms of area and mass value of wheat and sugar cane to the Australian economy is important cereals. In addition, oilseeds, sunflower crops and grain vegetables are widely grown in Australia for human utilization or dairy cattle feed. Australia produces a few cultivation products such as tomatoes, apples, mangoes, oranges, carrots, potatoes, chestnuts and bananas. Wine industry is a booming Australian agriculture, especially Chardonnay, Shiraz and Cabernet Sauvignon assortments. The rich pastures and great climate of Australia provides adequate supply of dairy products. In addition, Australia trades such as fish, abalone, shrimp and lobster seafood. Figure 1: Agriculture in Australia Map Malawi Agriculture Agriculture is the biggest part of the Malawi economy, helping more than a third of GDP and generates more than 90% of the aggregate export earnings. Malawi has long been reliant on the agricultural segment, both as a leading foreign exchange earner, and for subsistence farming in rural areas. The major exports products such as tobacco, tea and sugar. The agricultural sector includes fisheries and forestry. Tobacco is an immense part of economic and social structures in Malawi. Malawi part in universal tobacco advertises overall, is a constrained one because of the relative little size of this country. This is plainly demonstrated in the table 1 below. Malawi has a vast share of the worldwide burley tobacco market. Burley tobacco is a brilliant tobacco having a high nicotine content and flavour are considered better than numerous different sorts of tobacco. Malawis climate and soil is particularly suitable for the production of burley tobacco. Malawi tobacco crop accounted almost 20% of the worlds burley production because of its high-quality burley, selling a higher price than most other sorts of tobacco. It was accepted, and still is by some tobacco in general, especially in Burley, will assist in the development of Malawi, allowing the rural poor farmers in the production and sale of moderately high esteem crops. Almost the majority of the tobacco produced in Malawi is traded. The greater part of these tobacco exports are obtained by industrialized countries, specifically the United States and European countries. The domestic consumption of tobacco production is less than 2% in Malawi.

Standard of living can be defines as the level of riches, solace, material products and necessities are accessible to a certain financial class in a certain geographic range. For an example, if a person can buy anything he wants means that he is high standard of living, but a low standard of living person who doesn’t have enough water or food to drink and eat. The expectation for everyday life incorporates elements, for example, pay, quality and accessibility of business, class divergence, destitution rate, quality and reasonableness of lodging, hours of work needed to buy necessities, terrible household item, swelling rate, number of excursion days for every year, moderate get to quality social insurance, quality and accessibility of instruction, future, occurrence of malady, expense of merchandise and administrations, foundation, national financial development, monetary and political soundness, political and rel igious opportunity, natural quality, atmosphere and security. Standard of Living in Australia Australia’s standard of living is similarly high compared to other regions of the world, although there are gaps between citizens. Australia also has a group of Aboriginals who have been for throughout the years underestimated by the European pilgrims. This underestimation has prompted a gigantic distinction between the living models of the Europeans and the indigenous tribes. There is additionally a critical divergence in the living benchmarks of the Australian city inhabitants and the rustic tenants. Australia has a standout amongst the most prosperous economies on the planet. This monetary development is additionally overall reflected in the way of life of individuals. Urban communities like Melbourne and Sydney has a diverse and lively way of life. World Bank has recognized Australia as one of the wealthiest nations of the world in 1995. In the year 2006 the GDP is $1 trillion. The development of the economy is around 3.3 % for every year. The Purchasing Power Parity (PPP) of Australia is one of the most noteworthy on the planet. With the high development of Australian economy the nation has kept up a low development rate of swelling and investment. The administration of Australia puts very in the social and wellbeing framework. Australian high living measures and offices are additionally the motivation behind why the nation pulls in such countless every year. The gigantic rate of relocation from different nations of the world has transformed Australia into a blend of different societies. At first it was just the English who had relocated into the nation however after the Second World War the situation changed essentially. Since 1950 there was migration from all over Europe and later Immigration from Asian nations likewise occurred. The developing economy, the simple way of life and inconvenience free migration techniques are the fundamental purposes for this. The Organization for Economic Cooperation and Development association asserts that in the most recent 15 years the development of expectation for everyday comforts has been wonderful in Australia. Inside a couple of years Australia has surpassed the eight nations and is simply abandoned United States. A country’s standard of living is evaluated mostly by three variables its assets, prosperity of the populace and the quality of life. Australia is the best in health services and educational facilities. The World Health Organization likewise affirms this nation for having a low wrongdoing rate than most parts of world. STANDARD OF LIVING IN MALAWI Not surprisingly all relies on upon where you mean, standard instead in the rustic regions are much the same as in other Southern Africa nations, generally town based, houses produced using nearby materials, mud blocks, and grass tops and so on. Around the local area the lodging is all the more regularly mud block or concrete piece with grass or iron sheeting as tops. Lilongwe the capital is genuinely created however lingering behind the improvement going ahead in other neighbouring nations like Zambia. Malawi is a poor nation regarding pay, numerous individuals live around the destitution line, towns in rustic zones will exist on subsistence cultivating, harvests of cassava, corn and tomatoes makes up a substantial piece of the eating regimen, mice are likewise on the menu in Malawi, and are gotten and sold as delicious snacks. Business cultivating does passageways and tobacco, cotton, peanuts and tea are developed for money crops, principally being sent out to South Africa albeit a significant part of the cotton goes to Egypt. Malawi has a generally poor therapeutic base so the future is additionally low, that coupled with a high HIV rate implies the normal future is around 38-40 years. There is some low level revolutionary action in the northern ranges showing itself a bigger number of as groups attempting to auto jack than all else. Different levels or wrongdoing are generally low, other than the common negligible law violations in some more touristy regions. Malawi is undeveloped has next to no by the method for industry so subsequently has unemployment issues, exacerbating the destitution. Malawi for all its blames is a wonderful nation and exceptionally different from the swamps to the good countries, the high country levels are cooler and have some interesting natural life.

Private Schools vs. Public Schools Essay -- School Reform, Education Re

Would you change your school? Would you go to a private school instead of a public school? Or to a public school instead of a private school? Private and public education is different in many ways such as their performance, enrollment, and the overall education taught but yet they have somewhat similar teachers.   Ã‚  Ã‚  Ã‚  Ã‚  Students’ performance in public and private schools differ a lot. Private schools often have better grades and test scores. It is proven that kids who go to a public school and attend a private school perform better (Williams 17). Student performance varies but the advantage would probably have to go to the private schools.   Ã‚  Ã‚  Ã‚  Ã‚  Teachers in private and public schools are similar yet have some differences. There are about 2.7 million teachers and other faculty members in public schools (Klieg 22). There are about 400,000 teachers and other faculty members in private schools (Klieg 22). Of all these teachers only about 71% of private school teachers are licensed where 97.4% of public teachers are licensed (Williams 61). That makes the public teachers sound good, but there is also this little fact that they’re leaving out. Public school teachers aren’t even qualified to be teaching the subjects that they teach a lot of the time (Williams 46). Perhaps this is why the private school students are doing better than the public school students are. Or maybe it is because the average student to teacher ratio is better than public schools. This ratio is 17 students to 1 teacher in public schools where it is 14.9 students to 1 teacher in private schools (Williams 46). A good reason why private education is made out to be so much better than public schools is not necessarily because of the teachers, but the way private schools are able to hand pick each one of their students (Phillips Internet). Most likely they are going to pick the richest and smartest students they can. Why the richest and the smartest? Well if they pick the richest students it’s going to help the school financially. While the smarter students make the school and their teachers look good. So all in all teachers are all pretty equal besides maybe a few differences. How about teachers and their salaries? Teachers who are getting paid less are probably going to do a worse job right? WRONG! Private school teachers are usually paid about 12,000 dollars less than public school teachers ... ...ver child they want into their school. Who know, but it seems that public education can and needs to be improved maybe slightly more than private education.   Ã‚  Ã‚  Ã‚  Ã‚  Is money really the answer to everything? Some may think that their school does not have enough money and that’s why their students are doing so poorly. But more than likely money doesn’t play such a big part in the academic achievement of the students in school. For example: New Jersey is rated number 1 in terms of money per a student but yet they’re rated 29th in the basic student achievement (Williams 192). So before you blame your poor education on insufficient funds next time stop and think of these little facts. So what’s this saying? Maybe money is not the answer to everything.   Ã‚  Ã‚  Ã‚  Ã‚  So therefore private and public education is similar to an extent. However they do show many differences also. As shown they were different in their performance, enrollment, and the overall education taught. Private and public schools don’t have that much in common, but are their things that they do have in common but just didn’t get mentioned? Yes there are many more topics that are similar and different that we didn’t get into.

Teaching Adults: Is it different? :: Education School Essays

Teaching Adults: Is it different? The adult education literature generally supports the idea that teaching adults should be approached in a different way than teaching children and adolescents. The assumption that teachers of adults should use a different style of teaching is based on the widely espoused theory of andragogy, which suggests that "adults expect learner-centered settings where they can set their own goals and organize their own learning around their present life needs" (Donaldson, Flannery, and Ross-Gordon 1993, p. 148). However, even in the field of adult education, debate occurs about the efficacy of a separate approach for teaching adults. Some believe that adult education is essentially the same process as education generally (Garrison 1994) and therefore does not require a separate teaching approach: that is, all good teaching, whether for adults or children, should be responsive in nature. The question of whether teaching adults is different remains ambiguous. For example, research summarized in an ERIC Digest(Imel 1989) has shown that even those educators who say they believe in using an andragogical approach do not necessarily use a different style when teaching adults. Additional myths and realities related to teaching adults are explored in this publication. Two areas are examined: types of adult learning and what learners themselves want from teachers. Different Types of Adult Learning One way to approach the question of whether teaching adults is different is by examining the types of learning in which adults engage. Drawing upon the work of Habermas and Mezirow, Cranton (1994) classified adult learning into three categories: Subject-oriented adult learning-In adult learning contexts that are subject oriented, the primary goal is to acquire content. The educator "speaks of covering the material, and the learners see themselves as gaining knowledge or skills" (ibid., p. 10). Consumer-oriented adult learning-The goal of consumer-oriented learning is to fulfill the expressed needs of learners. Learners set their learning goals, identify objectives, select relevant resources, and so forth. The educator acts as a facilitator or resource person, "and does not engage in challenging or questioning what learners say about their needs" (ibid., p. 12). Emancipatory adult learning-The goal of emancipatory learning is to free learners from the forces that limit their options and control over their lives, forces that they have taken for granted or seen as beyond their control. Emancipatory learning results in transformations of learner perspectives through critical reflection (Mezirow 1991). The educator plays an active role in fostering critical reflection by challenging learners to consider why they hold certain assumptions, values, and beliefs (Cranton 1994).

Introduction to Phonetics

INTRODUCTION TO PHONETICS Communication is possible only with use of language. A language can be used in two ways for the purpose of communication . The two purpose of communication is spoken and written. Speech is more important medium than the medium of writing. USES OF SPEECH: *Speech comes first in history. *Speech comes first in the history of any individual. *Speech is used much more than writing as a medium, *Written language is an attempt to represent the sands used in spoken language. * Modern technology has given more importance to speech.Linguistics is a systematic study of language. Phonetics is a branch of linguistics and it is the branch dealing with the medium of speech . It deals with the production, transmission and reception of sounds of human speech. THE AIR STREAM MECHANISM: Speech needs air stream. The air stream that flows out of our mouth is modified into speech sounds by the action of creation organs of our body these are commonly known as â€Å"ORGANS OF SPE ECH†. For the articulation of most speech sounds lung air is used.The respirative system consisting of lungs, muscles of chest and wind pipe (trachea). since the air steam mechanism involves (inspiration) breathing in and breathing out (expiration). It is the expiratory lung-air that becomes the basis for the articulation of most of the speech sounds. The air stream involving in lung-air is called Pulmanic Air-stream. There are three main air streams mechanisms 1. Pulmanic 2. Glottalic 3. Velaric The Pulmanic air stream mechanism is initiate by the walls of the lungs. The air is drawn into

Ionic Bonds Essay

The hebdomadary tabulate is a masterpiece of organized chemic information. It is a shelve of the chemical substance elements in which the elements be arranged by revisal of instalmentic number. The standard form of the table includes periods (horizontal rows in the periodic table) and groups (vertical rows in the periodic table). Atoms are the basic building blocks of ordinary bicycle matter. Atoms are made up of particles called protons, electrons, and neutrons. Protons do a positive electrical charge, electrons sway a negative electrical charge, and neutrons melt no electrical charge at all. The protons and neutrons come together in the commutation part of the atom, called the kernel, and the electrons orbit the nucleus in the electron cloud. An element is a warmheartedness that is made entirely from one compositors case of atom.For example, the element hydrogen is made from atoms containing a single proton and a single electron. If you mixed bag the number of proton s an atom has, you change the type of element it is. There are 117 divergent elements. According to the atomic model, electrons orbit the nucleus at specific levels, or drums. Electrons deal shells, starting from the innermost, going to the outer(prenominal). Electrons in the outermost shell, which are involved in bonding, are known as valence electrons. When many another(prenominal)(prenominal) types of atoms come into contact with one another, electrons net be transferred from one atom to another thus creating an ion. An ion is an atom that has lost or gained an electron. Ions form because neutral atoms become aerated by the losing or gaining an electron. An anion is created when one atom gains electrons.On the contrary, a cation is created when an atom loses electrons. The eight rule is a simple chemical rule that states that atoms tend to attract individually other in such a way so that they each render eight electrons in their valence shells. The octet rule is applic able to the main-group elements, especially carbon, nitrogen, oxygen, and the halogens (five nonmetal elements found in group 17 of the periodic table), but also the metals in the first two columns of the periodic table.In simple terms, the octet rule says that atoms are more stable when their outer shell is filled, and therefore, atoms will lose, gain, or share electrons to entirely fill their outer shells. An Ionic enhance is a bond between a positively charge molecules (cations) with a negatively charged molecules (anions). Ionic compounds are organize between a metal and a non-metal. The metal loses the valence electrons to the non-metal thus forming dome bonds due to the attraction between the cations and the anions.

Most Effective Kicks in Tae Kwon-Do

Some throw ins ar more useful than others, so Ill be walking you through with(predicate) the more or less h one and only(a)stly/ strong electric charges that ar In take in Swoon-Do. Lets go through the attributes of a abandoning, well aim bump off with the human bottom oarlock, the complication that rest on the ground during the surge. This ramification Is just as Important (If anything more important) than youre bitch branching, due to the fact that this tholepin has to buckle under you the flexibility to initiate the wince back and to a fault has to maintain balance throughout the kick.Whenever you take shovel in a kick, you should allow the frankfurter of the derriere of your cup of tea forking to e raised(a) or so upward (Thus resting on the chunkock of your alkali) to maintain maximum mobility while the kick is in motion, allowing you to round of golf in the right stake for the kick. If you need to shift your position as your Initiating the kick. You sight also gliding/ skip on the crackpot of your foot toward the in demand(p) direction.The genu of your cornerstone subdivision should be moderately bent whenever you fulfill a recoil proficiency, this adds to the over-all balance of your be you will be able to coordinate your position easily, by adding more or less bend to your human knee, to compensate for the vizor and velocity of our kick. Now onto the dramatic leg, initiative off you never really motivation to fully extend your leg when kicking. The knee of the strike leg should remain slightly bent. This is accomplished by maintaining muscle inhibit over the lower embark on of your leg, and not allowing the impulsion of the kick to force your leg to hyper extend.Because the knee joint is one of the virtually sensitive joints of the human organic structure be sure to keep two knees slightly bent, to prevent them hypertension or turn backward unnaturally. Side tear The raw material fou nt kidnapping, is performed by initially break the majority of your body eight to your base leg as your striking leg (Be it your prior or rear leg) rises up with a bent knee to waistline level. As your striking leg rises, you turn on the glob of your base foot so your heel is facing your aim. Your body leans sideways toward the ground as your striking leg is extended toward your hindquarters.The impact is do with the heel or outside ridgepole of your foot. You hatful substantially Increase the concatenation of the side embrangle by allowing the whim of its impel to drive you onwards. To do so, go in into a fighting stance and demoralise by launching the side rupture with the bm or rear leg. Round. By performing the side snap in this fashion, you allow your base leg to slue board slightly forward across the floor, propelled by the momentum developed when your striking leg is launched toward its rear end. Not only does this add to the score of the kick, but also increases its place as sanitary, due to the fact that the force of your good body is behind it.One of the main problems with delivering the sliding side snap is that many muckle will release the kicks designer in the beginning they atomic number 18 in range of their target. When performing the side snap in this style, it is assertive to remember not to unleash your striking legs power from your hip, until your target is close and you are sure of making clutch with it. If this kick is done to far from your target, the most you tin hope to accomplish is that your extended leg will make touching tactual sensation with your opposite word. You will not, however, have any enfeeble impact. Therefore, keep your side snap abjure until target impact is ensured.Turn- round Side Snap Structurally similar to the side snap, the turn-around side snap is a spinning variableness of the staple fiber side snap. This kick is punish by first turning your top round, keeping an eye on you r target. You turn your head simultaneously pivoting your body on the crank of the foot of you lead base leg so that the heel of your base leg is facing your opponent. Your kicking technique is thusly launched from rear-leg position, in side kick fashion The turn-around side snap is a muscle-driven technique. Impact with this kick is made with the heel or the outside ridge of your foot.The sample targets for the turn-around side snap are your opponents knee, middle or head The turn-around side snap substructure be apply both offensively and offensively it can be used as a ace offensive movement or as a rapid faction of kicks jump from one foot to the next. It can also be used en gardely as a counter attack when your opponent is throwing a punch or a kick that haves him open. All-Around Swing boeuf The well-rounded swing kick is one of the most powerful techniques in a ingest Swoon- Do practitioners kicking arsenal. The momentum this kick can have has a devastating effe ct upon any endeavor it strikes.The all-around swing kick is execute by turning your head around behind you, to make sure your target hasnt moved, as you multitudinously pivot 1800 on the ball of your base foot. Your rear leg stirs off the ground and proceeds toward its target in a circular fashion. This kick strikes its target with the back of your heel. The all-around swing kick is most useful when delivered to the head or mid- branch of your opponent. It is important to drive your kick to go through your target, in other words, you dont indispensability to stop Just as you shit your target, you want the kick to follow through.Doing this well result in greater power and making it harder to defend against. Like most kicks, the all-around swing kick can be used justificatoryly or offensively Front Snap The front snap, is one of the first kicks that all Ate Swoon-Do students learn. Most devastatingly effective offensive/defensive techniques in your kicking arsenal when performe d correctly. The elemental front snap is performed by go in into a traditional fighting stance. You then launch your striking leg forward by readily raising the knee of your striking leg up to the desired height (It all depends on where you mean to attack, be it the head, mid-section or legs).The lower section of your tricking leg is then immediately snapped outward-bound in the direction of your target. The front snaps power is developed by a combination of upper-leg muscle strength and lower-leg snapping momentum. The impact of the kick can be made with each the instep of your foot of the ball of your foot. To strike with the ball of your foot, you need to bow out back your toes, exposing the ball of your foot. Performing the front snap with the ball of your foot is more advanced and takes superfluous practice.Through continued practice, however, the ability to instantly shoot back your toes will become impound natural. The reason it is so important to pull back your toes (Even if you are wearing shoes), is that if you leave them in their naturally extended position, they can easily be broken when target impact is made. The basic front snap is an ideal close- contact fighting weapon. As us commonly understood, a front snap to the groin of any undivided is universally debilitating. Other close-contact targets for this kick include the solar plexus, the stomach, or the bottom of your opponents Jaw.Axe waive The ax kick, is a close-contact offensive and defensive weapon. The axe kick is performed by quickly raising your striking leg (Depending if your kicking with your front or rear leg), in a linear fashion, and then forcefully bringing your heel/ball of your foot, down onto the shoulder/chest/face of your opponent. The basic axe kick is only effective in close-contact infighting situations, but it is quite lucky to extend the range of this kick. Enter into a fighting stance and prepare to launch an axe kick from your preferred leg front of rear (although its mainly used with the rear leg).Now instead of performing it with your leg locked into position, visualize a target several(prenominal) feet in front of you. Quickly lift your striking leg. As you target. There are two ways to execute an axe kick the traditional axe kick is brought inward, across your body, and then down-ward onto its target. The out-to-in axe kick is swung outward and is then brought down onto you opponents shoulder. The out-to-in axe kick is also a close- contact infighting weapon. It can most effectively be dispatched when your attacker has been taken hold of your clothing, or you have hold on his.Then, interchangeable before, the kick is quickly brought up and delivered to your opponents shoulder region Conclusion As we can see, kicks play a huge part in Ate Swoon-Do, we only went through 4 different kicks, there are many other (Such as bunco kick, turning kick, swing kick, crescent kick, all-around hook kick, all-around swing kick Etc,). Kicks d ont need to be complicated or hard to perform in ordain to be effective, like we went through at the start, for a kick to be effective in combat, it needs to be fast, unenviable to block and able to get through youre opponents guard and hit its target.

young Lady Macbeth reveals the anxiety of being captured within her fantasies.â€Å"Hie thee hither that I may pour my high spirits in thine ear, and chastise with the valour of my tongue† (Act1 Scene5 Lady Macbeth). A obedient servant then comes to tell her that Macbeth and the other lords are on how their way, and Duncan will be spending the night in their castle. young Lady Macbeth, straight away, sees this as an opportunity to murder Duncan. She starts to call dark spirits upon her to take away what her womanly kindness.For Macbeth, it becomes excessively simpler.â€Å"O, never shall sun that morrow see.† (Act 1 Scene 5, Lady lady Macbeth – Macbeth). She then tells Macbeth her plan to kill Duncan. part She tells Macbeth she will do all the planning.

Lady Macbeth manipulates her very nature to meet her function in the murders.All the lords, Macbeth, Duncan, his two sons, Malcolm and Donalbain, Banquo, Lennox, Macduff, Ross and Angus are all at Macbeth’s castle.

At the fresh start of the play, Lady Macbeth appeared to be a put girl.† (Act 1 Scene 7, Macbeth – young Lady Macbeth).Lady Macbeth seems to be very unimpressed with what Macbeth has said. She then tricks exalted him into continuing on with the murder as she questions his bravery. â€Å" With thou esteems’t the ornament of life, and live a coward in thine own esteem.Macbeth is a fairly dense read with lots of information and assorted characters.Lady Macbeth busy waits in a chamber near Duncan’s bedroom. Macbeth goes off to murder Duncan. young Lady Macbeth had got the chamberlains drunk so they wouldn’t see any of the murder. Lady Macbeth says deeds that the chamberlains make a joke of their jobs by falling asleep.

Dunnetts Macbeth is much more practical.â€Å"My heavenly father as he slept, I have done’t- My husband!† (Act 2 Scene 2, Lady Macbeth) lady Macbeth had brought the daggers back with him, the one he killed Duncan, Lady Macbeth new sees them and panics. â€Å" Why did you bring these daggers from the place?† (Act 2 Scene 2 , Lady Macbeth – Macbeth).

When she comes back she tells Macbeth deeds that they need to hurry to their bedroom so they don’t get caught.It delivers no simple answers.â€Å" What’s the business, that such a hideous trumper.† (Act 1 Scene 3, Lady Macbeth – Macduff). Macduff doesn’t want to scarce tell Lady Macbeth what happened , as he thinks she won’t cope. â€Å"O , gentle lady, tis forget not for you to hear what I can speak† (Act â€Å" Scene 3, Macduff – Lady Macbeth).
