Brain Development And The Process Of Learning Languages Psychology Essay

Brain Development And The Process Of Learning Languages Psychology Essay A baby speaks directly to the camera: Look at this. Im a free man. I go anywhere I want now. He describes his stock-buying activities, but then his phone interrupts. Relentless! Hang on a second. He answers his phone. Hey, girl can I hit you back? That scenario has been very common in commercials and movies throughout the past 15 years in which the majority of viewers perceive it as unrealistic and very comical. Joshua Hartshorne published a article called Why Dont Babies Talk Like Adults? in Scientific American Mind which attempts to answer the question: Why dont young children express themselves articulately? Researchers are uncovering clues about the brain development and the mysterious process of learning a language by attempting to answer the question: Why dont young children express themselves articulately?, in which they have discarded the copycat theory. Which states that infants learn to express themselves articulately by copying what they hear. In other words infants will listen to the words that are used by adults in several situations and later on imitate them accordingly. But adults have not been expressing them in one word sentences or even in short sentences. Therefore, the copycat theory does not explain why toddlers are not fluent as adults, but brings us to a very critical question why do infants speak in one-word sentence? Over the past century scientists have settled on two reasonable possibilities. First theory is called Mental Development Hypothesis which states that infants speaks in one word or short sentences because their brains are still immature and much undevelo ped. Therefore, they cannot dominate adult speech. The supporting argument is that infants do not learn to walk until their body is ready; likewise, they will not speak multiword sentences or use word ending and function words before their brains is capable of doing so. The second theory is called Stages of Language hypothesis, which states that speech is an incremental step progress. A basketball player his or her jump shot before learning to both jump and shoot, and children learn to add and then multiply, never in the reverse order. For instance, in a 1997 review article published by two cognitive scientists, Elizabeth Bates of University of San Diego and Judith C. Goodman from University of Columbia found that kids usually begins speaking in two word sentences only after they have learned a certain amount of single words. In other words children must cross a linguistic threshold so the word combination process can be developed. The differences between both theories are: Mental D evelopment Hypothesis states the patterns in language learning should depend on a childs level of cognitive development and Stages of Language Hypothesis states that learning language patterns are not dependable on the brain development. However, to prove which has hypothesis is correct has been extremely difficult because most children learn language at around the same age, thus in similar stages of cognitive development. But 2007 Harvard neuroscientists Jesse Snedeker, Joy Garen and Clarissa L. Shafto found an ingenious way around the problem. They studied the language development of 27 children adopted from China between the ages of two and five years. International adoptees are ideal population in which to test the competing hypothesis about how language is learned because many of them are no longer exposed to their birth language after arrival in U.S and they must learn English similar way infants do, by listening and by trial and error. Even though those international children had a more mature brain, just as American born infants, their first English sentences consisted of single words and were largely bereft of function words, word endings and verbs. The researchers also found that adoptees and native children started combining words in sentences when their vocabulary reached the same size. Therefore, it suggests that what is relevant is not how old a child is or how mature their brains are but the number of words they know. The finding that having a more mature brain does not avoid the toddler talk stage suggests that infants speaks in one word sentences or even short sentence not because they have a infant brain but because they having only initiated the process of learning an language. In fact they must accrue sufficient vocabulary to be able to expand their conservations. In conclusion infants do not express themselves as adults because language development is a gradual process. Therefore, Stages of Language Hypothesis is the most supported theory. The article Why Dont babies Talk Like Adults By Joshua Hartshorne was published Scientific American Mind. Scientific American Mind has been bringing its readers unique insights about developments in science and technology for more than 160 years therefore I had curiosity analyze the information that has been shared with so many readers throughout years. The structure of the article was not very organized. I had to read the article more than once so I could identify theories of language development therefore the structure of his article made it difficult for the reader to identify his main arguments. Although, Hartshorne does very good job in introducing, explaining and concluding each theory. He also provides his reader with a scientific research conducted by Harvard neuroscientists that analysis The Adoption Effect. He should have explained a little more in depth about experiment procedures so the readers could know how it was conducted. Also in his conclusion he does not tie the hi s final arguments to the initial question: Why dont young children express themselves articulately? But he leaves it to the reader to tie it together. I did not agree to the sentence: Behaviorism, the scientific approach that dominated American cognitive science for the first half of the 20th century, made exactly this argument. It is very inaccurate to claim that behaviorism ever dominated cognitive science because Cognitive science is one approach to the study of human behavior, Behaviorism another approach. He should have explained more in depth that cognitive science which is normally chosen to contrast with the approach taken by behaviorists, who preferred to study behavior without recourse to such notions as thought or the mind. Future research made me acknowledge that behaviorism and cognitive science co-exist, with behaviorism being the elder approach by fifty years or so. Overall, his article was informative and correct although should have been more scientific. Joshua Hart shorne also did not go into the mechanical or scientific area of language Development therefore it provoked me to research the topic more into depth which seems to be the purpose of Scientific Mind articles.

God’s Responsibility for the Fall of Man

God’s Responsibility For The Fall Of Man Within Literature, an unofficial definition for human wrongdoing has been connected to Adam and Eve’s expulsion from Eden. Their incompetence of following God’s orders, resulting in the punishment of mankind, has been thoroughly outlined within the text of the Bible. Yet are their actions truly of their own? God’s inept decision creating man within his image and His disdain leadership left human beings in a inferior position to disobey his orders, leaving him solely to blame for their ignorant actions.The power of leadership is a critical factor that even figures of immortal stature need to practice. God’s first mistake leading to the fall of man lies within decisions to create an entity upon the earth similar to him. â€Å"And God created the human in his image, in the image of God He created him, male and female He created them† (Simon 98). Why would someone create a figure of life within his own lik eness without giving them the same amount of freedom?Regardless of his position as the ultimate Creator, the expectations set within creating life forms with authoritative intentions similar to his own leaves God’s image as a wise leader questionable. His kind nature may have been proposed as good intentions, but the lack of decisive decision-making leaves him exposed to lacking thorough process for leadership. Another essential factor of successful leadership is to be supported by followers who believe in their leader.Adam & Eve’s actions within the Garden of Eden are more appropriately noted as a poor lack of leadership then a story of betrayal and self-disobedience. Within chapters 1-3 of Genesis, the persuasive words of the Snake easily motivate Eve to break God’s command and strive to eat the forbidden fruit. â€Å"For God knows that on the day you eat of it your eyes will be opened and you will become as gods knowing good and evil† (Simon 99). If Go d’s leadership was sufficient enough, how could this even take place?God’s insufficient leadership over his creations allowed Adam & Eve to be easily swayed by the leadership of an animal which he placed them in power to control. This is confirmed in later chapters of Genesis 6-9 where he makes the ultimate decision to dispose of all things he gave life to. â€Å" I will wipe out the human race I created from the face of the earth, from human to cattle to crawling thing to the fowl of the heavens, for I regret that I have made them† (Simon 101).For a leader to dispose and restart his initial intentions due to regret shows that mistakes have been made by that individual. And God’s decision to do so emulates that the fall of mankind was not of his subjects, but of his own disdain leadership skills. In conclusion, God’s poor decision making led to the evident fall of mankind. His actions were that of a leader who had well intentions, but had a poor pe rception of his follower’s involvement to his leadership. If he were more methodic in his decision making, he would of never regretted his choices made during the seven days of creation.

Evaluation of the Effectiveness of Accouniting Information System Essay

Abstract- In this study the effectiveness of accounting information systems from finance managers of listed companies at Tehran Stock Exchange is evaluated. The results indicate that implementation of the accounting information systems at the companies under study caused the improvement of managers decision-making process, improving internal controls, improving the quality of the financial reports and facilitated the process of the company’s transactions. The results did not show any indication that performance evaluation process had been improved. Key words: Accounting Information Systems, Quality of Financial Reports, Internal Controls, Decision Making, Performance Evaluation. INTRODUCTION In managing an organization and implementing an internal control system the role of accounting information system (AIS) is crucial. An important question in the field of accounting and management decision-making concerns the fit of AIS with organizational requirements for information communication and control, Nicolaou (2000). Although the information generated from an accounting information system can be effective in decision-making process, but purchase, installation and  usage of such system is beneficial when its benefits exceeds its costs. Benefits of accounting information system can be evaluated by its impacts on improvement of decision-making process, quality of accounting information, performance evaluation, internal controls and facilitating company’s transactions. Regarding the above five characteristics, the effectiveness of AIS is highly important for all the firms. An AIS is defined as computer-based system that processes financial information and supports decision tasks in the context of coordination and control of organizational activities, Nicolaou (2000). LITERATURE REVIEW Accounting information system is considered as a sub system of management information system (MIS). Regarding accounting as information system perhaps is the latest definition of accounting. For the first time in 1966 the Statement of Basic Accounting Theory, published by the American Institute of Certified Accountants (AICPA), stated that: â€Å"Accounting actually is information system and if we be more precise accounting is the practice of general theories of information in the field of effective economic activities and consists of a major part of the information which is presented in the quantitative for†. In the above definition, accounting is part of general information system of an economic entity. Boochhold (1999) defines accounting information systems as systems that have function of data gathering, processing, categorizing and reporting financial events with the aim of providing relevant information for the purpose of score keeping, attention directing and decision-making. Accounting information systems are considered important organizational mechanisms that are critical for effectiveness decision management and control in organizations, (Galbraith, 1983; Zimmerman, 1995). Systems will be useful when information provided by them is used effectively in  decision-making process by the users. Otley (1980, 325) argues that Accounting System are an important part of the fabric of organizational life and need to be evaluated in their wider managerial, organizational and environmental context. Therefore, the effectiveness of accounting information systems not only depends on the purposes of such systems but also depends on contingency factors of each organization. Accounting information systems are said to be effective when the information provided by them serves widely the requirements of the system users. Effective systems should systematically provide information which has a potential effects on decision-making process, Ivest et.al. (1983). The effectiveness of accounting information systems has long been a subject of many research, (Chong, 1996, Chenhall and Moriss, 1986, Kim, 1988, Mia and Chenhall 1994).Accounting information usually are categorized under two categories; 1) information that influence decision-making and mainly used for the purpose controlling the organization and 2) information that facilitate decision-making process and mostly used for coordination within an organization, (Demski and Feltham, 1976, Kren, 1992). Huber (1990) argues that, integration of accounting information systems leads to coordination in organization which in turn increases the quality of the decisions. Some research in accounting show that the effectiveness of accounting information systems depend upon the quality of the output of the information system that can satisfy the users’ needs, (Cameron, 1986, Lewin and Minton,1986, Quinn and Rohrbaugh, 1983, Deone and Mclean, 1992, Kim, 1989). Generally, accounting information systems; 1) provide financial reports on a daily and weekly basis and; 2) in addition provide useful information for monitoring decision-making process and performance of the organization. Simons (1987) in his study we used the first part of the above statement as measure of control for management and the second part for evaluating the effectiveness of the accounting information systems via continuous monitoring. By reviewing research studies during 1987-1999, one finds out that 57 research has been conducted on the issue of accounting information systems and decision-making. Therefore, it shows the importance of the research in  this area. Accounting information systems provide primary data for decision-making. Information technology has caused many changes in reporting information. Thus, the characteristics of information currently prepared can help decision-makers to seek more alternatives to the solution of the problem in hand. Accessibility to information related to the main transactions of an organization leads to a categorized detailed information which facilitates decision making in any difficult situation, Sutton and Arnold (1995). Accounting information system, is a computer based system that is defined by Nicoloau (2000) as a system that increases the control and enhance the corporation in the organization. Management is engaged with different types of activities that are requiring good quality and reliable information. They require also non-financial information such as production statistics, quality of production and so on. However, quality of information generated from AIS is very important for management, Mckinnon and Bruns (1992). Kim (1989) argues that usage of AIS depends on the perception of the quality of information by the users. Generally the quality of information depends on reliability, form of reporting, timeliness and relevance to the decisions. Effectiveness of accounting information system also depends on the perception of decision-makers on the usefulness of information generated by the system to satisfy informational needs for operation processes, managerial reports, budgeting and control within organization. Some research indicate that the effectiveness of accounting information systems depend on the quality of output information that satisfy the users, Cameron (1986), Lewin and Minton, (1986), Quinn and Rohrbaugh, (1983), Delone and Mclean, (1992) and Kim, (1989). Effectiveness of accounting information systems can be analyzed on three basis: 1)- information scope, 2)- timeliness, 3)- aggregation. Information scope is considered as financial and non-financial information, internal and external information that is useful in prediction of future events. Timeliness quality is related to the ability of accounting information system to satisfy informational needs by providing systematic reports to the users of information. Aggregation of information is considered as means of collecting and summarizing information within a given  time period, Choe (1998). Doll and Torkzadeh (1988), for studying the satisfaction of the users’ of information use some concepts to measure the effectiveness of the accounting information systems. These concepts are information content, accuracy, format, ease to use and timeliness. HYPOTHESES After reviewing relevant literature, five main variables and three moderator variables were hypothesized. Hypothesis 1: Accounting information systems leads to better decision-making by managers. Hypothesis 2: Accounting information systems leads to more effective internal control systems. Hypothesis 3: Accounting information systems enhance the quality of financial reports. Hypothesis 4: Accounting information systems improves performance measures. Hypothesis 5: Accounting information systems makes financial transaction process easy. MODERATOR VARIABLES Hypotheses based on moderator variables are set up to see whether such variables have any impact on the respondents’ responses to the research questions. One expects that such variables do not influence the way that respondents reply to the questions in the questionnaire. Hypothesis 1: There is a relationship between the levels of respondents’ education and evaluation of the effectiveness of accounting information system. Hypothesis 2: There is a relationship between the job experience of the respondents and evaluation of the effectiveness of accounting information system. Hypothesis 3: There is a relationship between the field of respondents’ education and evaluation of the effectiveness of accounting information system. RESEARCH METHOD Sample and data collection This study is based on the companies listed at Tehran’s stock exchange. No specific time period is considered since it is not a time series study. A  questionnaire is designed and after pilot study was sent to the sample firms. A population of 347 companies has been listed at Tehran’s stock exchange up to 1383. These companies are distributed along fifteen industries. Our sample has been randomly selected using sampling with no replacement process. For this purpose the below formula: 2 2 N ZÃŽ ±/2 ÃŽ ´ X n = ————————— 2 2 2 Ã'” (N-1) + ZÃŽ ±/2 ÃŽ ´ X 22 347 ( 1.96) (0.29) n = ———————————— = 95 (0.05)2 (347-1) + (1.96)2(0.29)2 Based on the ratio of the companies in each industry to the total number of companies in the population, the number of companies in each industry for the sampled firms was determined. The main data collection instrument in this study is questionnaire. For this purpose a questionnaire was designed after reviewing the relevant literature. The questions are on the five point Likert type questions, with a choice of very little to very much. The questionnaire consists of twenty questions, which were carefully designed to collect relevant data. The research instrument was pilot studied, by expert panels including faculty members. The revised instrument and a cover letter were mailed to the specific individual who was listed as financial managers of the sampled firms. A reminder was sent and non-respondents were followed up with two additional mailings. In the first questionnaire launching 54 questionnaires were completed and returned. In the second and third mailings a total of 33 more completed questionnaires were returned. Altogether 87 questionnaires were available for data analysis in this study. STATISTICAL TESTS To test the hypotheses of this research we have used z and χ2 statistics at confidence level of 95%. The research hypotheses were put in the form of statistical hypotheses such as H0 and H1. With regards to the nature of five-point scale questions, therefore, we test whether the mean value of each question is less than or greater than 3. Number 3 is the average number of the five choices in each question: 1+2+3+4+5  µ = ——————- = 3 5 Thus, statistical hypotheses are set up as follows: H0:  µ ≠¤ 3 H1:  µ > 3 Testing moderator variables: to test the moderator variables and see whether they have any impact on the main variables, in this research χ2 tests were conducted. TESTING HYPOTHESES AND ANALYZING THE RESULTS To study the research hypotheses eighty seven finance directors (financial managers) were selected as final sample in this study to answer the question put forward to them in the questionnaire. The data collected in this way was edited and some questions merged to measure each hypothesis. Average number of 3 was taken as the mean of the five-point questions in the questionnaire. Table -1 shows a descriptive statistics of five hypotheses. Table-1 Descriptive statistics MinMaxStd.Error of KurtosisKurtosisStd. Error of SkewnessSkewnessVarianceStandard DeviationModeMeanStd.

Z statistic concerning the test of first hypothesis is equal to 6.47 (table-2 ).By comparing this value with the critical value of 1.645, we accept H1 and reject H0. Therefore, the first hypothesis is accepted indicating that implementation of an accounting information system in an organization could improve decision making by managers. The average of the questions measuring this hypothesis is 3.227 and the skewness of -1.087. The kurtosis of 0.094 indicates that the distribution of our data is slightly taller than normal distribution with 0.322 standard deviation. Thus, we could conclude that our respondents on average and slightly above the average believe that accounting information systems lead to better decision-making by managers. Results of the second hypothesis: Accounting information systems leads to more effective internal control systems. Table-2 shows the Z value of testing the second hypothesis equal to 5.389. Again, comparing this value with the critical value of 1.645, we accept H1 and reject H0. This indicates that from the respondents’ point of view accounting information systems would lead to better internal control systems. Descriptive statistics shown in table-1 gives the average of 3.224 to the questions measuring the second hypothesis, skewness of 0.568, kurtosis of -0.799 and standard deviation of 0.442. This information indicates that the distribution of our data is slightly shorter than normal distribution.

Gold and north Carolina Essay

Gold and north Carolina Essay Gold and north Carolina Essay American History I chose to discuss Christopher Bechtler for the topic of my paper because he was a person of many talents and I can show the different aspects of Christopher Bechtler and his family, Christopher sailed to the United States in 1829 from Le Havre, France, he soon after arrived in New York City with his two son’s Augustus, Charles and brought along his nephew Carl Bechtler. Christopher Sr. soon opened up a small Jewelry shop in Philadelphia, Bechtler intended to stay and make Philadelphia a final place to call home being that his nephew was newly married to his German-American wife Sophia Fleck with whom he had four son’s and three daughters with, Bechtler decided to move him and his entire family to Rutherfordton, North Carolina in hopes of becoming a gold prospector I see that Mr. Bechtler was a man of many talents and ambitions nothing was impossible for him if he could gain some finical wealth from it. On April 25, 1830 Bechtler decided to purchase a tract of land in Rutherford County from a gentleman named John Bradley, being Bechtler was not yet a citizen of the United States yet ,he in trusted a German-American man named Martin Kibler to hold the title to his land, three months later Bechtler officially became a citizen of the United States of America. Bechtler consistently needed assistance with translators as well as witnesses for legal transactions; Bechtler never took advantage of learning the English language he knew bites and pieces of the English language to get through tolerable conversations, I believe Bechtler made the move from Philadelphia to West North Carolina in 1830 because there was a finical gain for him and his family and the opportunity for his business to flourish as a clock and watch maker, so Bechtler posted an advertisement in the North Carolina Spectator and the western Advertiser that he was open for business, I also believe that Bechtler was in the midst of a gold rush, this was one and certainly wouldn’t be the last place that gold was discovered in the United States. Being that North Carolina was the first place in the United States to have founded gold in this state by John Reed in 1799, there weren’t any kind of major mining operations that begun until 1825, that’s when gold bearing vein quartz was found in the hillside in North Carolina, by 1830 the gold rush was plentiful and very profitable at this time North Carolina gold production was valued at more than half a million a year, to be more pacific there was a worth alone in 2011 of 12.6 million dollars made in 2011, this gold was shipped overseas or sent to the Federal mint in Philadelphia, most of the gold stayed in the region, I do believe that this what was tempting to Bechtler to make the decision to move to North Carolina gold can be used for a number of things; like art work being used in a dust form, Bechtler has an obvious need to create jewelry out of the raw material called gold. Bechtler finally had sir-combed to gold fever himself in hopes of getting rich, in 1837 Bechtler decided to dig a tunnel 80 feet deep on this tract of land he had purchased in 1830, Bechtler sought out information from a British geologist George Featherstonhaugh, Featherstonhaugh told Bechtler that his land wasn’t very promising for gold and to have such an extensive dig, but Bechtler wouldn’t give up that easily on his dream to strike it rich, you know when a person has dedication to something like this when they put this as their last will and testament that â€Å" our ore will be found good†, just reading about Bechtler and his many ventures into profitable businesses made me think if the gold digging didn’t pan out he could always fall back to what he knew; which was fine custom made jewelry, which ultimately became his first business in North Carolina, he opened a watch and jewelry store in Rutherfordton, he wasn’t just a† one trick pony† as it were put he sold rings, earrings, necklaces, collar buttons,

Complete the Statistical Process Control for the Process Term Paper

Complete the Statistical Process Control for the Process - Term Paper Example Leading tools in Statistical process control are control charts, which is based on constant perfection and premeditated testing. Control charts, also recognized as process-behavior charts. In statistical process control, control charts are key practice utilized to establish whether or not a production or commercial process is in a condition of statistical control. The control chart can be envisioned as ingredient of a purpose and regimented approach that permits acceptable judgments concerning organization and management of the process, as well as whether or not to alter process control constraints. Process constraints should never be altered for a procedure that is in proper organization, as this will consequence in despoiled process routine. Being insightful of a process, the process is characteristically mapped out and the process is controlled using control charts. Control charts are utilized to recognize disparity that may be due to special causes, and to liberate the consumer f rom apprehension over disparity due to common causes. This is a nonstop, continuing process. When a procedure is steady and does not activate any of the detection rules for a control chart, a process competence analysis may also be carried out to forecast the capability of the present procedure to manufacture compliant products in the upcoming activities surrounded by specifications. A control chart comprises of points on behalf of a statistical mean, range, and proportion of dimensions of a quality feature in illustrations (samples) opted from the procedure at dissimilar points in time. The mean of this statistic process control utilizing the entire collections of the sample is enumerated; it incorporates the mean of the means, mean of the ranges, and mean of the proportions. A middle line is placed at the numerical value of the mean of the statistical process control chart. The standard error meaning the standard deviation/sqrt(n) for the mean of the statistic is in addition preme ditated by means of the entire collections of all the samples. Upper and lower control limits, at times termed as "natural process limits", designate the threshold at which the procedure output is measured statistically improbable are drawn characteristically at 3 standard errors starting from the center line. The chart can also be additionally equipped with possible features, like upper and lower warning limits, placed as detached lines, characteristically two standard errors on top of and underneath the center line, as well as separation into zones, with the accumulation of regulations leading frequencies of interpretations in every zone in addition to it can also encompass the explanation with procedures of interest, as explicated by the Quality Engineer in command of the process's quality. Control charts put 3-sigma or 3-standard error limits on the few foundations, these foundations include the common consequence of Chebyshev's inequality that the probability of an occurring bi gger than k standard deviations as of the mean is at mainly 1/k2 for any probability distribution. The better-quality product of the Vysochanskii-Petunin inequality that the probability of a event larger than k standard deviations as of the mean is of the value maximum 4/(9k2) for any uni-modal probability distribution. The empirical examination of various probability distr

Rabies Research Paper Example | Topics and Well Written Essays - 1750 words

Rabies - Research Paper Example This research paper outlines the rabies disease, its history, signs and symptoms. Rabies was well identified in Europe at some stage in the medieval times, and was in all probability transmitted to the New World, where it became widespread in North America and the West Indies by the eighteenth century and in the early nineteenth century it reached South America as well. Record of the disease in Asia is not well recognized but rabies has been in existence since the early times in China and India. Scientific studies on the disease were started in the year 1803 by Zinke who discovered the transmission of the disease by saliva. Louis Pasteur had developed the view that rabies is a disease of the CNS. Vaccinations were thereby worked on and gradually discovered over time. The time period between the initial infection and the onset of the symptoms usually takes around four to eight weeks or it may be a year at times, depending on the distance between the CNS and the site of infection. The initial symptoms in a rabies disease include fever, headache, fatigue, pain at the place of the wound, and even loss of appetite. Symptoms with respect to the two different forms of rabies have been identified. The symptoms of furious rabies include anxiety and agitation, neck becoming rigid, seizures, tears and saliva overproduced, convulsions, enlarged pupils, unusual understanding of light and temperatures, fear of water, insomnia, partial paralysis, hallucinations, abnormal mental clarity, and confusions.
