Glass essays

Glass essays Glass is a material that is used in our homes, workplaces, and forms of transportation. It is most commonly seen in the form of windows, which protects us against the elements without obstructing our vision. In our vehicles, we use it to see places that we would normally have to turn around to see. In eyeglasses and contact lenses it allows us to see better. It conducts heat easily, but does not conduct electricity at all. It is also used for decoration such as vases, clocks, mirrors, and even stained glass. Glass is commonly referred to as a highly viscous liquid. It is not a solid because its molecules arent in a crystalline pattern. Instead, the particles are arranged as if it were a liquid, but frozen in place. It can be transparent, translucent, or opaque. It is non-porous, non-absorptive, and can be used with the common elements and many harsh chemicals and liquids. It is one of the best electrical insulation materials, and because it is made of silica or contains it, it is considered a ceramic. It is also considered a thermoplastic in some cases because it can melt when heated and reform when cooled over again. First appearing in nature, glass existed before man discovered it. A common natural glass is obsidian, the molten glass from volcanoes. Obsidian is composed of three ingredients; sand, soda, and lime. The same ingredients in different amounts also make up manufactured glass. About fifty other chemical elements are used in modern glassmaking to give it desired properties. Glass is an open chain of silicon atoms with atoms of various oxides occupying the spaces between. The loose structure is what permits its transparent property. Today, the average batch mix used to manufacture flat glass products is about seventy percent silica sand, thirteen percent lime, twelve percent soda, and small amounts of other additives. One quarter of the batch is cleaned and crushed glass from ...

Application Of The Behaviourist Perspective Psychology Essay

Application Of The Behaviourist Perspective Psychology Essay Operant conditioning is a process of learning, it was found by Burrhus Frederic Skinner BF Skinner. Skinner invented the operant conditioning chamber, also known as the Skinner Box. He innovated his own philosophy of science called radical behaviorism, and founded his own school of experimental research psychology – the experimental analysis of behavior. His analysis of human behavior culminated in his work Verbal Behavior, which has recently seen enormous increase in interest experimentally and in applied settings. Operant conditioning is a type of learning in which an individual’s behavior is modified by its consequences; the behavior may change in form, frequency, or strength. Operant conditioning is distinguished from classical conditioning in that operant conditioning deals with the modification of voluntary behavior or operant behavior. Operant behavior operates on the environment and is maintained by its consequences. Classical conditioning (also Pavlovian condi tioning or respondent conditioning) is a form of learning in which the conditioned stimulus (CS), comes to signal the occurrence of a second stimulus, the unconditioned stimulus (US). (A stimulus is a factor that causes a response in an organism.) The conditioned response is the learned response to the previously neutral stimulus. The US is usually a biologically significant stimulus such as food or pain that elicits a response from the start; this is called the unconditioned response (UR). The CS usually produces no particular response at first, but after conditioning it elicits the conditioned response (CR). Classical conditioning differs from operant or instrumental conditioning, in which behavior emitted by the subject is strengthened or weakened by its consequences (reward or punishment). This perspective is most useful in explaining our different ‘Learned’ behaviours. It lets us look at a specific behaviour and see where we got it from and how we got it. Changing behaviour is where we change our behaviour sometimes because of maybe a fear or phobia. Classical conditioning is used for explaining these but it is also good for helping us change these behaviours. There is a method to change phobic behaviour, this is called ‘Systematic Desensitisation’. You would put together a list of things that relate to the fear, and relax to the point where you are comfortable enough to look at the thing without being scared. Then you would move up to the next level of it. For example, if you were afraid of spiders, you would get comfortable with seeing a picture of a spider, then the next level would be having a spider in the room with you but in a cage, and this could progress up to you being able to hold the spider. This is called a ‘Hierarchy Of Fear’. Classical conditioning has also been used to treat other things like alcoholism, they are given a drug, when that drug is mixed with alcohol it causes them to feel sick and be sic k. They then associate alcohol with sick and unpleasantness. Application of the Social Learning Theory Social Learning Theory suggests that many things can influence our behaviour. This could be things like; Peers, Siblings, Parents, Television, Sports, Personalities and celebrities. If we see someone we admire behaving in a certain way, we are more likely to imitate them. Albert Bandura is a famous Psychologist at Stanford University. For almost six decades, he has been responsible for contributions to many fields of psychology, including social cognitive theory, therapy and personality psychology, and was also influential in the transition between behaviorism and cognitive psychology. He is known as the originator of social learning theory and the theory of self-efficacy, and is also responsible for the influential 1961 Bobo doll experiment. He felt that learning did not have to be conditioned or reinforced all the time. New behaviour could be could be learnt by observing others. Observational Theory refers to learning of a new behaviour through watching someone else perform the behaviour. This behaviour can be learnt but does not have to be reproduced unless the individual is motivated to perform the new behaviour. Role Theory suggests that because we live in a certain culture, come from a certain religion or are friends with certain types of groups, we adopt certain roles as we are expected to live up to certain expectations. It also suggests we change our roles to suit our environment. Bandura also thinks that our behaviour is influenced by the presence of others.

Facebook is none of such social networking platforms, which I being heavily used by the people of all age groups. According to Myers (2010, p. 1), â€Å"Facebook is a social networking website intended to connect friends, family, and business associates†. Although this website and other social networking media provide many benefits to people, such as, developing kinship and other relationships, information sharing, entertainment, social interaction with people from different societies, and facility to find old friends, but there are also some harms associated with the heavy use of these media.

Internet is allowing us to explore once more. Crystall concludes that a surprisingly small number of new words have been spawned while texting, blogging and other forms have given radical opportunities to develop new stylistic rules. He believes that the new forms of interaction seen in the Internet are far more important than changes in vocabulary, grammar, and spelling. Finally, as the internet becomes more linguistically varied, it also extends a hand to minority languages and it speakers. It helps speakers of minority language to maintain virtual contact through email, chat and instant messaging environments. The recent technologies like email and text messaging will transform language in a way that certain words might become obsolete.

Choose my words wisely and think before I speak.

Hostage Negotiation Essay -- essays research papers fc

  Ã‚  Ã‚  Ã‚  Ã‚     Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Hostage and barricade incidents are amongst the most difficult, emotional, and sometimes potentially lethal situations that a negotiator can be involved in. Often, the hostage taker shows signs of mental illness, drug or alcohol intoxication, or personal disputes accompanied by a high level of emotion. (Feldmann) These contributing factors lead to impulsive and often unpredictable behavior on the part of the hostage taker. It is sometimes impossible for negotiators to anticipate possible outcomes and complications that could arise from these incidents. Negotiators use a wide variety of tools, information, and strategies to try and resolve whatever grievances and demands the perpetrator is exhibiting. The main focus on the part of the negotiator is to keep the hostage alive, then try to negotiate a surrender. There is a considerable risk to both the victims and law enforcement when dealing with a hostage situation. (Feldmann) This paper will ide ntify and distinguish several high risk factors that negotiators and law enforcement use to extinguish potentially lethal situations. The presence or absence of these factors can influence the outcome of a situation for the better or for the worst. Second, this paper will identify several motivations for hostage taking. Why and what would prompt an individual to take hostages? Several influential and background reasons will be examined. Finally, some successful and also failed negotiations will be explored, with possible reasons and explanations to what factors made them either a success or a failure.   Ã‚  Ã‚  Ã‚  Ã‚  Hostage negotiation is as much of an art as it is a science. The negotiator not only holds the lives of the victims in his hands, but the lives of law enforcement and the hostage taker as well. His persuasiveness and communication abilities have the power to protect and save lives. The Hostage Taker   Ã‚  Ã‚  Ã‚  Ã‚  One of the most common reasons for a hostage taking situation is desperation. The hostage taker feels desperate because of either what he has done or what he is doing. (DeFao) Taking a hostage is a split second decision usually made out of desperation. (DeFao) A person who is in the process of committing a crime, for instance a bank robber who has been surrounded or confron... ...he presence of high-risk factors, consider all other intelligence available, and combine this information with the assessments made by both the negotiation and tactical teams. This combined information will assist in differentiating between a genuine hostage situation, and a pseudo-hostage situation. The success or failure of the situation ultimately lies in the persuasive and communication abilities of the negotiator.

This assignment are knowing a batch of information about Traditional bing method and Activity based costing and besides alterations of direction accounting. The treatment will be divided into two portion, which are first portion calculated traditional costing method and activity based bing from the information that given. After that pupil need give definition, advantages, disadvantages and differences. of both traditional costing method and activity- based costing, First discuss about of Scooter Driver based on the issues raised by each of the managers. The 2nd portion will be discourse the coursework pupil have to give the alterations of direction accounting over the past decennaries and besides the impact of the alterations in direction accounting. Current Method Production Cost Per Unit Net income(Entire 4 180 000 2.0 Activity-Based Costing Method 2.1 Production Cost Per Unit+2.2 Net income–Entire 4 180 000Traditional costing methodTo: Director of ScooterDriver From: Management Accountant Rhenium: Measure the Absorption Costing and Activity- based costing The traditional method refers to the allotment of fabricating overhead costs to the merchandises manufactured ( Hansen, Mowen, 2006 ) . The traditional method besides known as the conventional method assigns or allocates the mill ‘s indirect cost to the points manufactured on the footing of volume such as the figure of units produced, the direct labor hours, or the production of machine hours ( Huntzinger, 2007 ) . The traditional costing system merely has one or a few indirect cost for each section or whole works nevertheless the application of cost in the traditional costing system is usually based on an indirect cost driver cost applications are frequently financially ( Drury, 2007 ) . The traditional attack to bing of merchandises basically utilities a system whereby the entire cost to bring forth a figure of merchandises are divided between the assorted merchandises by doing usage of the traditional costing system, it therefore means that all the cost incurred have to be allocated to one or other merchandises ( Coombs, Hobbs, Jenkins, 2005 ) . Besides, traditional costing system tend to utilize a smaller figure of 2nd phase allotment bases, typically direct labor or machine hours and often the traditional system presume that direct labourhave a important influnces in the long term on the degree of overhead outgo ( Drury, 2004 ) . Traditional costing system besides use indirect cost to merchandises based on a predetermined operating expense rate, to boot the traditional costing is optimum when indirect cost are low compared to direct costs and there are several stairss in the traditional costing procedure ( Bhimani, 2006 ) . The job with this attack is that for most overhead activities, the proportions of the activity really consumed by a specific merchandise, does non cosmopolitan correspond with a individual cost driver and this holds true for most modern companies where merchandises are produced by a combination of work force and engineering ( Horngren, 2007 ) . The traditional cost accounting theoretical account employs a volume-based driver, such as a direct labor hours or machine hours for the assignment of all fabricating overhead cost therefore the conventional cost accounting theoretical accounts ends up with a cost of goods sold based on soaking up costing and includes merely merchandises costs are defined in fiscal accounting ( Jiambalvo, 2009 ) .Activity Based CostingABC ( Activity Based Costing ) is a system that attempts to accurately follow indirect costs to merchandises by apportioning indirect costs to activities and so to merchandises based on their use of the activities ( Drury 2004 ) . ABC is optimum when truth is really of import and when indirect costs comprise a big proportion of entire costs compared to direct costs and ABC is besides normally used in the fabrication sector ( Finkler, 2003 ) . ABC is so utile for the fabrication sector is reasonably obvious, by apportioning indirect costs to merchandises based on use, a company can more accurately see where the resources and energy is traveling in their company. ( R. Hansen, M. Mowen, Guan, 2007 ) . It will calculating out where the money and energy is traveling, attempts can be focused upon those merchandises that are eating up the most clip and energy and this finally lead to a bead in cost, in theory, as attempts will be made to cut down the costs on the majority of the merchandises. ( Hansen, M.Mowen, Guan, 2007 ) . Activity based costing system besides used to find merchandise costs for particular direction studies ( Weetman, 2006 ) . This system is normally used as a addendum to the company ‘s usual costing system. Most organisations that use ABC systems have two bing systems are known as the functionary bing system that is used for fixing external fiscal studies and the activity based bing system that is used for internal determination devising and for pull offing activities. ( Drury, 2004 ) . ABC systems differ from traditional system by holding a greater figure of centres in the first phase and a greater figure, and assortment, of cost drivers or allotment bases in the 2nd phase ( Drury, 2004 ) . Activity based costing ( ABC ) was developed to get the better of the defects of the traditional method. Alternatively of merely one cost driver such as machine hours, ABC will utilize many cost drivers to apportion a maker ‘s indirect costs. ( Weerman, 2006 ) .Differences between ABC and traditional costing methodTraditional cost accounting system and ABC have some similarities, for case both have two phases whereby resources costs are pooled before being assigned to be objects. The first phase pools indirect costs in production cost centres ( in convention system ) or in activity centres in ( ABC system ) ( Narayanaswamy, 2008 ) . The 2nd phase allocates operating expenses to be objects utilizing volume realated bases direct labor hours, direct labor cost or machine hour s or a mixture of both volume and non-volume related bases in ABC system ( Narayanawamy, 2008 ) . However, despite these similarities several characteristics differentiate the two system, foremost in traditional costing system merely fabricating operating expenses usually allocated to be objects, whereas fabrication and non-manufacturing operating expenses are assigned in ABC system ( Bierman Jr,2010 ) . Another, an ABC system normally has well more cost pools ( based on activity centres ) than a traditional system ( based on production sections ) ( Banjerjee,2007 ) . Furthermore ABC uses more sophisticated and complex allotment bases, peculiarly during the 2nd phase of following costs to merchandises. ABC advocates argue that these differences make ABC system superior as the provide directors with more dependable information about merchandise costs ( Bierman, Jr.,2010 ) . Traditional cost accounting pattern are accused of often overrating the cost of high volume merchandises and undervaluing those of low volume 1s, epically when operating expense are less related to volume ( innes and Mitchell, 1998 ) . In contrast to traditional cost accounting system, ABC system are non inherently constrained by the dogmas of fiscal describing demand instead, ABC system have the built-in flexibleness to supply particular studies to ease direction determination sing the cost of activities undertaken to plan, bring forth, sell, and present a company ‘s merchandises or services ( Patra, 2006 ) . This flexibleness is the fact that ABC system focal point on roll uping costs via several cardinal activities, whereas traditional cost allotment focuses on roll uping costs via organisational units ( Needles, Powers, Crosson, 2006 ) . By concentrating on specific activities, ABC systems provide superior cost allotment information, non-volume-based cost drivers cause epically when cost. Even so, traditional cost accounting system will go on to be used to fulfill conventional fiscal coverage demand, ABC system will go on addendum, instead than replace, traditional cost accounting system ( Ramchandran 200 7 ) . Finally, traditional coasting and ABC can differences by costs associated with a merchandise can be categorized as a direct costs and indirect costs ( Drury,2007 ) . Direct cost, is the cost which can be identified with the merchandise, while indirect cost are non straight accountable to a cost object for illustration cost of stuffs, direct labor cost such as rewards and wages are illustration of direct cost ( Ryan,2004 ) . Administrative costs and depreciation are some of the illustrations of indirect cost the ground to placing entire cost of a merchandise are really of import to find the merchandising priceof that merchandise ( Stolowy, 2006 ) .Deduction of activity-based costing for ScooterDriverThe remark by the finance manager is differing because Fireball is doing profitable with the bing system but unprofitable with the ABC system. The two systems can hold major impact on overall net incomes. The intent for the differences in merchandise net income is that Fireball has the low er volume but it makes the higher comparative demand on the three activities identified by the ABC system, because Fireball uses a lower proportion of direct labor hours than the other merchandises and the bing system allocates a lower portion of operating expenses to Fireball. The selling manager argues that incremental costs are required for the pricing determination. Consequently disagree with this because, its of import to separate between short term and long-run incremental costs. ABC seeks to describe long-run incremental cost chances will be lost to cut down capacity and the long-run incremental costs will stay unchanged. ABC distinguishes that longer term incremental costs can be reduced by doing determination that guarantee that activities should be undertaken merely where incremental grosss exceed long term incremental costs. It is of import that facility-sustaining costs are omitted from the costs reported by the ABC system since they are neither short-run nor long-run incremental costs. Agree with the pull offing manager determination that the cost per activity should non stay changeless over the long term. Attempts should be made to cut down the costs of activities and better the efficiency. Therefore ABC reported costs should be made evaluated and adjusted at periodic intervals. There are besides some costs such as installation sustaining costs do non alter with activity and are non variable with any activities step. For illustration it could be costs excluded from the reported individually as installation sustaining costs. The president is true about the profitableness analysis based on keeping the same merchandise mix will give the same entire net incomes. However, different net incomes or loses are reported by merchandises and doing future determinations on the footing of ABC information compared with the bing system. Therefore have an impact on entire future net incomes such as, presuming that the costs reported by the ABC system are all based on cause and consequence relationship so a determination may be made to stop production of Fireball. This will non apparent in bing method but still, it is an of import that determination should non be based entirely on fiscal factors and non-financial factors should besides be taken into history.Question 2Changes and impact information engineeringThere a batch alterations information engineering ( IT ) make in our day-to-day concern environments. Most of them can be filed under the wide header of engineering such as the alterations that occurred in industrial harnessing of electricity. Not merely did workss and mills running off the recent power develop, full town substructures were changed to suit. Furthermore the available hours besides makes alterations and some companies began runing all 24 hours each twenty-four hours with third-shift workers. Besides, power lines became planetary throughout the state, as did telephone lines. Even today, these are considered indispensable pieces when equiping a proper office edifice and most concern inventions in the twentieth century involved plugging devices into walls electrical or telephone mercantile establishments but the twenty-first century has seen brooding accent on radio capablenesss. During the past decennaries the usage of information engineering ( IT ) to back up concern activities has increased dramatically and development of electronic concern communicating engineerings known as e-business, e-commerce or Internet commercialism have had a major impact. For illustration, consumers who have entree to the Internet are able to compare the comparative virtues of different merchandise and are more spoting in their purchases. E-commerce such as saloon cryptography has allowed considerable cost salvaging made by streamlining concern procedure and has generated excess grosss from the expert usage of online gross revenues installations. The adept usage of e-commerce has given companies a competitory advantage.Changing and impact of competitory environmentIn order to pack in today competitory environment company have had to go more client driven and do client satisfaction and on over reading priory. Customers are demanding every bettering degree of service in cost, quali ty, dependability, bringing, and pick of advanced new merchandises. Identify cost efficiency, quality, clip and invention as the cardinal success factors. In add-on to concentrating on this factor organisation are following new direction attack in their quest to accomplish client satisfaction. Excellence in fabrication can supply a competitory arm to vie in sophistic worldwide market. In order to vie effectual companies must be capable of fabricating advanced merchandise if high quality at low cost and besides supply a first category client services. Organization as those operating in the air hose and fiscal services industry were either authorities owned monopolies or operated in extremely regulated protected and non-competitive environment. These organisations were non capable to any greater force per unit area to better the quality and efficiency of their operation or Tom improve profitableness by component services or merchandise that were doing losingss. Compare to the increasing competition as besides made determination mistake due to hapless cost information more likely and more dearly-won. If the cost system resulted in destroy merchandise cost Begin reported, than the overhead cost merchandise willed to higher command monetary value in concern and concern loss to those rival to be able to cite lower monetary value ill because the cost system produce more accurate cost information. Alternatively there is a danger that under coasted merchandises will resulted in credences of unprofitableness concern.The changing and impact of globalisationIn the globalisation, international corporations have to cover with trouble and hazard confronting the concern. There are many differences in political system, accounting system of external study, legal system and civilization and usage in different states ( Pettersen, 2001 ) . In order to run successful concern abroad, it is important for directors to understand these differences and the income r evenue enhancements system difference is another cardinal factor. Management comptrollers must give careful consideration to local revenue enhancement jurisprudence and revenue enhancement rate, which may be different from domestic legal. Last, for the different pecuniary system, directors of transnational companies must be supervising the foreign exchange fluctuation continuously. So the universe economic system is influenced by many factors, and exchange rates fluctuate often and widely. When the corporations go abroad to set up contracts, make trade good minutess and run concerns, there are much more similar job they have to face. For direction accounting, it has to get the better of important barriers and troubles in the globalisation. The aim of direction accounting is altering. Before the globalisation, most corporations are little and chiefly relay on place operations. With the deepening of globalisation, endeavor graduated tables are increasing and travel abroad to serve their clients. The traditional accounting is ever concentrating on the domestic instead than the international market. These transnational corporations, confronting the tendency and demand of globalisation, have to redesign their accounting systems to fulfill the new planetary aims. The aims and ends of direction accounting are non merely domestic information, which is based on the historical information, but besides the planetary information, which help directors cut down complexness and hazard in concern. So the direction accounting should acquire the more exact and suited information of working capital and operation cost. Keeping a tight manus on this information, international concern can recover their competitory border. Excellent direction accounting can supply utile information to assist a corporation accomplish its ends and aims. First of wholly, it can give the scorekeeping of the concern, which accumulates and classifies the information. Based on the scorecard, internal directors can measure the public presentation of the concern. Second, the director accounting supplies important job, which should be looked into the attending directing. Attention directing respects to giving the director item and direct information, which makes them recognize the job, chances and challenges of the company. To work out jobs, direction accounting frequently make a survey to happen out the possible methods and the most appropriate option.The changing and impact Organizational constructionIn modern-day competitory scenes, organisations are progressively concentrating on factors that provide value to the client.

Harmonizing to the term â₠¬Å" horizontal organisation † has evolved to reflect patterns applied in companies that integrate activities across the value-chain to back up a customer-focus scheme Chenhall ( 2008 ) . Harmonizing to following new engineerings may necessitate alterations in organisational constructions and work procedures to better accommodate the capablenesss of improved engineering. Khandwalla ( 1974 ) , Thus, for better success, there is a demand for a alteration to organisational construction fostered by advanced engineering applications. Organizational design and construction represents the forms and relationships that exist among organisation or work unit elements in organisational construction ( Macy & A ; Arunachalam, 1995 ) . A alteration in construction can be in the signifier of new organisation structural, departmentalization, centralisation, decentalisation and accent that â€Å" organisation constructions are the merchandise non merely of coordinating demands imposed by complex engineerings, but besides of rationalized norms legalizing acceptance of appropriate structural theoretical accounts. The organisational construction variable draws to a great extent on the seminal plants of Bruns and Waterhouse ( 1975 ) , who identified several organisational features that were strongly related to the pick of accounting-control scheme. In drumhead, they found that as organisations and sections turn and go more complex, they tend to deconcentrate and implement a more administratively oriented control scheme, which involves a higher grade of behavior formalisation and an increasing usage of formal forms of communicating.

In contrast, smaller, more homogenous and centralised houses tended to trust more extremely on inform al, personally oriented control mechanisms such as direct supervising and face-to-face communicating. Consequently, houses were less reliant on formal usage of the budget when utilizing this interpersonal control scheme.The impact and altering economic growing ( authorities )The major economic environment backgrounds, such as great depression, authoritiess make accommodations through policy alterations that they hope will win in stabilising the economic system.

Therefore concern, now a twenty-four hours is vitally affected by the economic, societal, legal, technological and political factors. These factors jointly form concern environment. Business environment, as such, is the sum of all external forces, which affect the organisation and operations of concern. The environment of an organisation has got internal, operational and general lives directors must be cognizant of these three environmental degrees and their relationship and importance. The term ‘business environment implies those external forces, factors and establishments that are beyond the control ofA single concern organisations and their direction and impact the concern endeavor. It implies all external forces within which a concern endeavor operates. Business environment influence the operation of the concern system. Therefore, concern environment may be defined as all those conditions and forces, which are external to the concern and are beyond the single concern unit, but it operates within it. These forces are client, creditors, rivals, authorities, socio-cultural organisations, political parties national and international organisations. Some of those forces affect the concern straight which some others have indirect consequence on the concern

Politeness and Pragmatics in the Cross-Cultural Communication Essay

Introduction In this paper, we will examine the Natural Order Hypothesis which was first introduced by Stephen Krashen in the late 1970s and 1980s. Krashen proposed the Second Language Acquisition Theory with five hypotheses. The Natural Order Hypothesis is a part of this second language theory. This hypothesis claims that learners of second language acquire the grammatical structures in a predictable way. It includes that some grammatical structures acquired naturally earlier than the others and this synchronization does not affected by the learners’ native language, age or any condition of exposure. Using a case study approach we will observe whether this claim is valid in Bangladeshi context or not. To examine that how the Natural Order Hypothesis works in Bangladeshi context, we have chosen some Bangladeshi people from different ages. Some the students of first semester and second semester of University of Liberal Arts Bangladesh. We have asked them to answer some certain questions which have added in the last section. This paper is divided into several chapters. The first section of the paper introduces with the five hypotheses of Stephen Krashen’s Theory of Second Language Acquisition. The hypotheses are demonstrated one by one because all the hypotheses are interrelated. This part is concluded with some main points of criticism about the Natural Order Hypothesis. The next section of the paper analyses our examinations about the hypothesis. It includes the Findings and Results of the study. The last section of the paper explains recommendations and conclusion where we have given our opinion. Krashen’s Theory of Second Language Acquisition Stephen Krashen’s Theory of Second Language Acquisition is well accepted widely in all areas of second language research and teaching since the 1980s. This theory consists of five hypotheses. These are the Acquisition-Learning Hypothesis, the Monitor Hypothesis, the Natural Order Hypothesis, the Input Hypothesis and the Affective Filter Hypothesis. The explanations of these hypotheses are given below. The Acquisition-Learning Hypothesis The Acquisition-Learning Hypothesis states that there are two ways to  develop second language proficiency for adult learners. One is ‘acquisition system’ and another one is ‘learned system’. According to Krashen, the ‘acquisition system’ is a subconscious process. In this system, it is claimed that the development of the L2 proficiency goes through naturally. More like the way children acquire their first language. The learners acquire language without knowing about that acquisition is taking place. The main point is that learners develop proficiency through using language in meaningful conversations where the focus is on meaning not in the rules of language. On the other hand, ‘learned system’ is referred to ‘knowing about’ language. According to Krashen, the ‘learned system’ is a conscious and explicit process. Through this system learners learn about the language as a conscious study of formal instructions. That means the two systems are totally opposite. Krashen states that acquisition is more important to develop second language proficiency. Learning cannot lead to acquisition. He adds that conscious rule of ‘learned system’ only performs as one function; Monitor or editor. So the error correction occurs in ‘learned system’ which affects in learning language. But error cannot affect in case of acquiring language because in development of L2 proficiency, ‘acquired system’ only gives learner a ‘feel’ of error subconsciously. To demonstrate the Acquisition- Learning hypothesis, Krashen also denies about Noam Chomsky’s Language Acquisition Device (Device). Chomsky claims that humans are born with the instinct or â€Å"innate facility† for acquiring language. There is a ‘black box’ in every person’s brain and it acquires any language before puberty. Krashen disagrees and says that acquisition of second language can also happen after puberty. He further explains that LAD also works for adult but that does not mean that adult will always acquire second language as native speaker. He claims that LAD function also works for adult second language acquisition. The distinction between ‘acquisition system’ and ‘learned system’ can be seen in the table given below. The Monitor Hypothesis Stephen Krashen explains in the Monitor Hypothesis that how acquisition and learning are used in second language performance. This hypothesis holds the theory that utterance in L2 is initiated by the acquired system at first and after that the learned system works if there is any need of changes. Krashen includes that utterance of L2 happens generally through acquired linguistic competence. The role of learned system is work as a Monitor or editor. To use Monitor successfully, Krashen gives three conditions. These are time, focus of form and know the rule. 1. Time: The first condition explains that the acquirer must have enough time to apply the Monitor. The problem regarding this condition is, during normal conversation one cannot look after the time. If someone tries to use the Monitor he/she will fail to utter in right time or if someone tries to maintain the time he/she will fail to use the Monitor. The important part is that this condition can be applied only in case of advanced acquirers who use Monitor occasionally. 2. Focus on Form: The second condition instructs that the acquirers must focus on form of the language. The acquirers must think about the correctness of the form. But the problem is using Monitor with focusing on form is really tough. To maintain this condition one can lose the track whether he/she will Monitor what he/she is saying or he/she will Monitor how is he/she saying it. 3. Know the rule: The third condition is the acquirer must know the rule of language. It is very difficult condition to maintain because everyone does not know about all the rules. Even the best students may not know all the rules of the language which they are exposed to. So, these are the three conditions which drive to use Monitor successfully. But later on Krashen has mentioned only about the focus on form and know the  rule. He did not mention about the first condition ‘time’. Learnt knowledge (Monitoring) Acquired knowledge Output Figure: Model of adult second language performance On the other hand, Krashen has explained about three individual differences regarding use of the Monitor though the difficulties of three conditions remain dissolved. According to him, there are three types of Monitor users. Monitor over-users, Monitor under- users and the Optimal Monitor users. 1. Monitor over-users: This type of people use the Monitor all the time. They always check their output with the conscious knowledge of the language. Krashen claims two causes for this type of Monitor users. Firstly, they acquire language with the restriction of grammar instruction. Secondly, they may have acquired a good amount of second language but can not trust their acquired competence. That is why they always try check and cover their mistakes by using Monitor. So, they speak hesitantly and try to correct their utterances at the middle of a conversation. 2. Monitor under users: These types of people whether acquire language not learning or they do not prefer to use their conscious knowledge. Actually they do not use the conscious knowledge even when the three conditions are met. The self-correction happen only from a ‘feel’ of correctness. 3. The Optimal Monitor users: The optimal users are the people who apply the Monitor when it is necessary and appropriate. They know how to combine their learned competence with their acquired competence. They never use the grammar rules in their regular conversation because it can interfere in their utterances. This type of users most of the time achieve like the  native speaker in writing and planned speech. The Natural Order Hypothesis: According to Krashen the Natural Order Hypothesis deals with the grammar structures. The hypothesis explains that grammatical structures are acquired in predictable order. This order does not follow any rules that the easier grammar rule will be at first and then the complex one. It claims that there are some certain grammatical structures which acquired early by the learners of second language acquisition and then the others and it is for any given language. Krashen explains that the claim does not prove as 100% always, but there are some significant similarities. Krashen actually adopted this hypothesis from the study of Dulay and Burt’s study of what they called the order of acquisition of grammatical morphemes in English by five to eight year old children learning English as a second language (1974). They established a chart of morphemes for their study. So, Krashen adopt the idea of English morphemes and established his Natural Order Hypothesis. Krashen believed that there was no difference regarding the synchronization of the grammar structures. But later on Krashen develops his own idea about the order. He examines the study with both children and adult’s second language and illustrates the natural order of grammar structure according to his point of view. Table: Average order of second language acquisition in English. In further description about the Natural Order Hypothesis Krashen explains three facts. * Krashen claims that natural order cannot be changed. Teacher cannot change the order through drills or exercises. If a teacher tries to drill a certain rule for several weeks the result will be zero. Because the acquirer will only acquire language when it is ready to acquire the certain rule. This fact is very much related to the Affective Filter Hypothesis. * The natural order of grammar structures do not depend on any obvious feature. It can go through complex to easier or easier to complex. Some rules acquired later which are quite simple. On the other hand some rues acquired earlier which seem to be difficult in structures. It shows that curriculum designers might face problem that which one they should put earlier and which one in later. * The third fact is that the natural order is not the teaching order. So, if someone predicts that through learning the grammar structures he or she will acquire language proficiency, he/she might wrong. Because Krashen applied the Natural Order Hypothesis to extend the idea of ‘the Input Hypothesis’. The Natural Order Hypothesis actually helps to know how the comprehensible input can be acquired one by one. So the learners will acquire the language in a natural order as a result of getting this comprehensible input. Criticism of Natural Order Hypothesis: Krashen’s Natural Order Hypothesis faces many criticisms about the predictable natural order in second language learners’ acquisition of grammatical structure. His using of English morphemes as a model also causes criticisms. There are some important criticisms which really force linguists to rethink about Krashen’s Natural Order Hypothesis. These are, * Krashen claims that all L2 learners adopt the same nature of acquiring language to attain proficiency. However there is some individuality between learners. Every learner does not go through the same order of morphemes to  learn grammar rules. Some adopts the -ing form at first and later on go through the other rules step by step. On the other hand some adopts the pronoun case (he/she, his/her etc.) at first. So, Krashen’s hypothesis does not concern about individuality. * Another criticism explains that all languages do not have the same morphemes. Some languages do not have the function of Copula or definite/indefinite article. So as a result the learners from this type of languages face problem acquiring the morphemes though these are the simplest one. The learners pick up the morpheme according to their first language acquisition. Here, Krashen actually totally overlooked the possibility of the influence of L1 on L2. On the other hand he also ignored the role of negative and positive transferences. * Krashen claims that his model of natural order works for both adult and children. Critics raised questions about this generalization. That how did Krashen judge it as the both applied natural order for adult and children. Did the judgment was from instrument and task specific? A critic named Larsen-Freeman applied Krashen’s natural order model for both the adult second language learners and children second language learners and she found that the model really works but when she put it in some different tasks using different instruments, she could not found any similarity between adult learners score and children learners score. So, Krashen’s claim proved itself as unreliable because it does not work for every situation. So these are the criticisms regarding Krashen’s Natural Order Hypothesis. To evaluate our case study we have taken the help of these criticisms and we also found some problems in Bangladeshi context. The evaluation has given in the Analysis part. The Input Hypothesis: The Input Hypothesis gives the answer of the question that how we acquire language. Regarding this hypothesis Krashen states that, the learners acquire language by understanding input which is slightly beyond their  competence. He also adds that when the learners understand the messages of a language, they acquire language. The main theory of this hypothesis is ‘i+1’. Here ‘i’ is learners’ present competence and ‘i+1’ is the input of the language which can be understood by the learners. Krashen calls this ‘i+1’ as the comprehensible input. He not only states that but also strongly claims that ‘comprehending message’ can help to acquire language and there is no other fundamental process of language acquisition. Another point he claims that listening and reading comprehension are the primary important function of second language acquisition. There is one important point which should be noted that the Input Hypothesis and the Natural Order Hypothesis are interrelated. These two are combined to answer the question of how we move from one stage to another of acquisition. That means, Natural Order Hypothesis works for analyzing the Input Hypothesis that how learners move from ‘i’ to ‘i+1’. The Natural Order Hypothesis helps to decide that which one should be the comprehensible input or ‘i+1’ in the classroom. There are two corollaries in the Input Hypothesis. These are, 1. The first corollary is that speaking is not the cause of language fluency but the result of language accuracy. It cannot be taught directly. It is acquired through comprehensible input. 2. The second corollary is, if there is enough amount of comprehensible input the learner will automatically acquire competence from the teacher. There is no need to use grammar structure. That means there is no need to be finely tuned input which means the exact next grammar structure as ‘i+1’. It can also be roughly tuned input, like the nearer structures from the ‘i’. So, from this hypothesis we can understand that there is no need to use energy in acquiring language. The main important part is just to understand the messages. When we understand the messages of second language, the LAD starts to work. This is how we acquire language. The Affective Filter Hypothesis: The Affective Filter Hypothesis describes us that how people face obstacles to acquire second language. It tells us about a filter named ‘affective filter’ which works as an obstacle in the way of acquiring language. The affective filter does not work directly as a barrier but creates a ‘mental block’ in brain which prevents to acquire language. Krashen explains that if the affective filter is down then the comprehensible input reaches to the LAD and acquires competence but if the affective filter is up then the input does not reach to the LAD and acquisition does not happen. Krashen includes that there are some ‘affective variables’ which control this affective filter. The affective variables include motivation, self-confidence and anxiety. This variables help to acquire second language very easily. But if someone has low motivation, low self-esteem and debilitating anxiety the student will face difficulties to acquire language. Because these low motivation, low self- esteem and anxiety will ‘raise’ his affective filter and form a ‘mental block’ which will become an obstacle to understand the input and acquire language. So, the Affective Filter Hypothesis helps to determine that why a specific learner faces problem in dealing the comprehensible input though he/she has reached a native- like competence. The main point is one should have motivation, self-confidence and low anxiety if he/she wants to acquire second language. Many critics raised question against Krashen’s Theory of Second Language Acquisition. Some of them are reliable and the rest of them are from anti- Krashenites. From our opinion, though Krashen has applied many statements to prove his theory but the Natural Order Hypothesis really lacks in reliable informations. The hypothesis could not set with our Bangladeshi context. The discussion has given in the next section.

Is Larkin entirely cynical about the possibilities Essays

Is Larkin entirely cynical about the possibilities Essays Is Larkin entirely cynical about the possibilities Paper Is Larkin entirely cynical about the possibilities Paper In the poem Talking in Bed, Larkin displays a rather bleak and cynical view of lasting love. In the first stanza, Larkin uses a pun in the second sentence. Lying together there goes back so far The word lying can be looked at as physically lying, or the act of lying. Larkin shows his cynical side here as he talks of deceit in the relationship that goes back so far. I believe that Larkin means they are lying about their love for each other, that they dont really love each other but feel they have to because they have been together for so long. An emblem of two people being honest. This sentence follows on from the next in the way that they believe they are being honest by staying together, but really they know they dont love each other. Both are trying to convince themselves that they are doing the right thing by staying together. This pun is also used in An Arundel tomb in the first stanza. Side by side their faces blurred, The count and countess lie in stone. Here Larkin uses the pun to suggest whether or not the count and countess actually loved each other or whether this was just an act and their love was only perceived by their friends and family. This is shown in the third stanza. They would not think to lie so long. Such faithfulness in effigy Was just a detail friends would see. Larkin uses bleak metaphors to convey his doubts about love in Talking in bed. And dark towns heap up on the horizon. This sentence talks to me of problems building up in the relationship that will come to a head in the near future. Outside, the winds incomplete unrest Builds and disperses clouds about the sky. Here Larkin uses another metaphor. The winds incomplete unrest reveals the unease felt round each other and the incomplete is almost like there is something missing from the relationship. I think this is Larkins way of talking of a loveless relationship and this sparks off anger as conveyed in the following sentence. The build up of tension in the relationship flares up at times and the metaphor of clouds, to me, is the clouding of their relationship because of this lack of love. This is also shown in the final stanza; It becomes still more difficult to find Words at once true and kind Or not untrue and not unkind. This final stanza shows the deterioration of communication between the couple. Larkin says it is hard to find kind words or unkind words and so sees the relationship at its end. In the third stanza, Larkin says something very interesting. None of this cares for us. Nothing shows why At this unique distance from isolation. This is a very lonely statement because although they are together, they have isolated themselves from each other perhaps in an attempt to block out the fact they are living a lie by being together. In an Arundel Tomb, we see a slightly surprising line in which Larkin seems to be moved by. One sees, with a sharp tender shock, His hand withdrawn, holding her hand, Here we see another side of Larkin that perhaps thinks that their love was true because of the loving act of holding hands. The use of the word tender is also surprising because it is such a gentle word unlike some of Larkins bleaker metaphors. In the final stanza we see Larkin being as positive as possibl e about love. The stone fidelity they hardly meant has come to be Their final blazon, The word hardly suggests that their love wasnt quite meaningful but now together in stone they have no choice but to be together, whether or not they meant it to be like that . Our almost-instinct almost true: What will survive of us is love. Here I believe Larkin is saying that if anything survives it is love but nothing survives after we die. He is trying to say that it would be nice if love did survive but the love that has survived in this poem is the love that is set in stone and Larkin wonders whether or not this was real love or something comprehended by friends. In the poem Wild Oats we see another approach to love told in a story with the characters of bosomy rose and specs. This poem shows Larkins view of how love is unreliable and he speaks of it in a bittersweet way.

The biological theories, which may explain Schizophrenia Essay

The biological theories, which may explain Schizophrenia - Essay Example These concern genetics, neurochemistry, brain structure and evolution. Biological factors of Schizophrenia can be explained using studies on twins and studies on family history. With twin studies, researchers want to establish the degree of concordance. This is the likelihood that if one twin has the disorder, the other twin will also have it. Gottesman (2000) summarised 40 twin studies and found that the concordance rate for MZ twins was 48% and the concordance rate for DZ twins was about 17%. Concordance rates were also studied by Cardano et al. (2001) using the Maudsley twin registers. They found concordance rates to be 40% for MZ twins and 17% for DZ twins. Although this is strong evidence for biological factors in Schizophrenia, concordance rates are not 100% and therefore there must be some environmental input. Loehlin and Nichols (2002) argued that the reason for the higher concordance rates in MZ rather than DZ twins was due to MZ twins being treated more similarly so producing a greater environmental similarity. However, there are two arguments against this view. MZ twins may produce more similar treatment from their parents than do DZ twins (Lytton, 2000). This therefore suggests that the higher biological similarity of MZ twins may be the cause, rather than the effect, of their more similar parental treatment. In addition, the Schizophrenia concordance rates for MZ twins who are brought up apart are similar to those of MZ twins who are brought up together (Sheilds, 2003). So presumably the high concordance rates of MZ's brought up apart is not due to environmental similarity. However, it has been suggested that some of the twins who had been brought up separately in Sheilds study had not always spent their whole childhood apart and some were raised by relatives and even went to the same school (e.g. Kamin, 2001). Family studies also aid to explain how biological factors influence Schizophrenia. Gottesman (2000) found that if you have a sibling with the disorder you have an 8% chance of being Schizophrenic, if you have one parent with the disorder you have a 16% chance of being Schizophrenic and if you have two parents with the disorder you have a 46% chance of being Schizophrenic. These concordance rates should all be compared to the 1% chance that a person randomly selected from the population would be Schizophrenic. Gottesman and Bertelsen (2001) also reported some convincing findings on the importance of genetics. The found that participants had a 17% chance of being Schizophrenic if they had a parent who was an identical twin and who had Schizophrenia. This could be due to heredity or environment. They also found that participants had a 17% chance of being Schizophrenic if they had a parent who was an identical twin and did not have Schizophrenia, but whose identical twin did. This therefore shows that the most important factor is genetics. The evidence reported by Gottesman is criticised because although it indicates that Schizophrenia runs in families and that concordance rates are much higher between relatives who have higher biological similarity, it does not account for the fact that family members who are more biologically similar are likely to spend more time together. This means that environmental factors are also indicated in this

Web security authentication and authorization Research Paper

Web security authentication and authorization - Research Paper Example Authentication Mechanism If a particular resource needs to be protected,using elementary authentication mechanism,Apache server sends a header including â€Å"401 authentications† in repose to the request. As the user enter credentials,consisting of username and password,for the resource to be returned as requested. Moreover, as soon as 401 response headers receive by the web browser, it asks the user to specify username and password in order to authenticate the user. Similarly, the server will check the credentials in the safe list, if they are available; the resource is made available to the user. Securing the Contents For any individual resource on a web server, the methodology for securing contents includes actions in terms of step to configure elementary authentication procedures. The first step would be to create a password file. The second step is to determine the configuration in order to obtain the file containing passwords i.e. the password file. Moreover, the first step is to determine valid user credentials, consisting of username and password. Likewise, the credentials provided by the user are matched successfully to a valid username and password lists. The password file is created on the server to validate legitimate user authentication mechanism. However, the password file is a delicate and confidential piece of information and must be stored outside of the document directory in order to eliminate any potential threats from hackers or viruses. For creating a password file, a utility names as â€Å"htpasswd† is executed. It is â€Å"htpasswd is used to create and update the flat-files used to store usernames and password for basic authentication of HTTP users. If htpasswd cannot access a file, such as not being able to write to the output file or not being able to read the file in order to update it, it returns an error status and makes no changes† (Htpasswd - manage user files for basic authentication - apache HTTP server ). This utility is located in the â€Å"bin† directory of the Apache. For instance, it is available in /usr/local/apache/bin/htpasswd. However, for the creation of the file, certain commands are executed. For example, to create a password file these commands are executed: ‘htpasswd – c /user/local/apache/passwd/passwords username’ After executing the command, ‘htpasswd ’ will prompt the user for the password. Furthermore, after providing the password, the file is created. In order to add a new user to the password list, following command is executed: ‘htpasswd /usr/local/apache/passwd/passwords testuser’ This command will add this user credentials to the password file. In addition, the user name, named as ‘testuser’ is already created earlier on the webserver. After the creation of the password file, Apache configuration is conducted with the required directives. The directives are located in an ‘.htaccess’ file, on a particular directory associated with server configuration. Web Contents Prevention In order to maintain a sophisticated web server, web content prevention is essential to ensure the safety of web contents available on the web server. Apache ‘digest authentication’ is made for this purpose. It is a â€Å"method of authentication in which a request from a potential user is received by a network server and then sent to a domain controller† (What is digest authentication? - definition from whatis.com ). The command ‘digest authentication’ is executed on the module named as ‘mod_auth_digest’. This utility will never transmit the passwords across the network. In fact, these files are transmitted via MD5 digested passwords, eliminating attacks such as sniffing the network traffic for passwords. There are some steps incorporated in order to accomplish this utility from the Apache web server. Likewise, the configuration for digest auth entication is quite similar to the basis authentication. The first step involves the creation of a password file. The command executed for the creation
