Learning and Memory.An introduction to theories of learning EssayLearning and MemoryIntroduction Cleaning the path is the target doings in Bobbys case. Mr. Kelly tries to keep on reminding his eight year old child to clean his room but it is evermore in vain. Since Mr. Kelly needs friend in increasing the frequency of his child change his room it could be assumed that bobby is trained and knows how to clean his room. The possible reason as to why he keeps on refraining from this task is however unclear. Operant condition is a method of learning that incorporates acquisition of demeanour and facing the consequences of the behaviour. In this type of learning rewards argon given to the learner either to get on or discourage future repetition of the same behaviour (Olson Hergenhahn, 2013). Operant conditioning back spot be apply to encourage Bobby in cleaning up his room. Through the various components of operant conditioning Mr. Kelly can apply to encourage Bobby clean hi s room. Operant conditioning has dickens major concepts, reinforcement and punishment, which could be used in different ways to encourage bobby to clean his room. Reinforcement involves using reward that would otherwise increase the chances of bobby cleaning his room more often. Mr. Kelly could use various rewards such as giving bobby measure to watch T.V, buying little gifts that are issued each time bobby cleans his room. such(prenominal) motivating factors leave alone encourage bobby to clean up his room. Reinforcement is of two types, positive and ban reinforcement, both ways can be capitalised in ever-changing the behaviour of bobby. In positive reinforcement for instance Mr. Kelly needs to look for items such as toys or bars of chocolate, preferably Mr. Kelly could choose some of the items bobby loves just about and use them to reward bobby after cleaning the room. Continuous use of negative reinforcement over a long period of time would lead to Bobby matu balancen an at titude towards cleaning his room. Thus positive reinforcement could be applied. For reinforcement to be effective both method should be used concurrently. Fixed ratio schedule and variable ratio schedules can be used to implement and encourage bobby to always clean the room. Fixed ratio schedule will always reward bobby after a number of times he has cleaned the room. This method will give immediate positive responses from bobby but would be consuming for Mr. Kelly. inconstant ratio schedule would award bobby after irregular intervals of response from him. This can be very effective to reinforce Bobby to clean the room because the reinforcement can come all with the first week and make the reluctance of cleaning the house an extinct behaviour. I will apply the operant conditioning to account for Jackies development of the behaviour of phobia towards dogs. This is because the operant conditioning shows or explains why the organisms will acquire learned behaviour that they exhibit. The vital management of operant conditioning is by use of reinforcements as punishments or reward so as to increase or decrease the likelihood of occurrence or repetition of certain behaviour (Staddon Cerutti, 2003). In the case of Jackie, she received a negative reinforcement from the dog bite and hence the phobia towards dogs development. Also the stitches and the time that she spent on medication made her develop the negative attitude towards dogs. This is because, in operant conditioning, it is clear that continued use of negative reinforcement will lead to the victim developing an attitude towards that object or behaviour. Some of the behaviour modification that could be designed to help Jackie to overturn the phobia that she has with dogs could be Jackie could first of all spend time with her spouse with a company the trained dogs. This will help Jackie to see that dogs were not wild and they always do not bite any time you had an encounter with them. This will somehow help her reverse the phobia she had towards dogs and also help her see the positive side of the dogs. She should also be allowed to spend time with the trained dogs with the dogs being guided by the trainer to remain lively, obedient and helpful to Jackie. This will act as a positive reinforcement towards Jackies behaviour. She will slowly by slowly start liking dogs and hence they will have a skilful life with her partner thereafter. There are two main principles of operant conditioning that are evident in the case of Emma. First by the parents severe to offer Emma some kind of reward, they are trying to positively reinforce the behaviour of cleaning her room and toys through the principle of positive reinforcement. Also through putting her out, they are applying the principle of positive punishment by trying to add something bad so that she cannot repeat the same mistake. Operant conditioning surmise could be applied in this case to correct Emmas behaviour through application of the four main principles of operant conditioning. The parents could apply the principle of negative punishment which is to take something good away so as to decrease certain behaviour. Through application of this principle, they could cut away buying of toys to Emma so that she could be reinforced to clean the room. Also through negative reinforcement principle, which is taking something bad so as to reinforce behaviour could be applied by Emmas parents. They could stop putting her in time any time that she cleans her room so that she can be reinforced to always clean her room and toys. Extinction of behaviour in operant conditioning theory can be defined as the disappearance of previously learned behaviour if the behaviour is not reinforced (Hunt et al, 2008). As we have earlier said, reinforcement is the necessity for learning and in which certain behaviour grows. It is either a means to encourage or discourage certain behaviour (Olson Hergenhahn, 2013). For instance, the Emma is co nditioned to the behaviour that when she screams hard and through the toys away, her parents will collect them and clean them up for her. If the parents stopped this behaviour, Emma could not study this behaviour because it will lack reinforcement and slowly it will cease and become extinct.ReferencesHunt, Elgin F. and Colander, David C.

Mobile Phone Distribution Comparison: US and Myanmar

bustling Phone Distribution Comparison US and MyanmarINTRODUCTIONIt is not only when the lives of individuals had been changed since the introduction of busy visits, but also the future of the telecommunication sector. From a person informs his or her friends about changing in plans or dealing an international business with thickening or even a victim ask for overhaul when something bad happens. Mobile hollers are really all important(p) in todays society. The boundaries of space, clock time and size had been narrowed down finished the growth of the wireless communication sector.In the Americas region, there is a continuous growth and more than 50 pct of brainwave rates in the South and Central America in quick sector. While there are about 30 percent penetration rates in Peru, Honduras, Costa Rica, Bolivia and Nicaragua. On the other side, Argentina and Chile had 80 and 76 percent of penetration rates respectively.While in Asia-Pacific region, Myanmar and Kiribati had e xtremely low vigorous phones penetration rate, which is 1 percent. In Taiwan, Singapore, Macao, Hong Kong and Australia, the penetration rate are 90 percent. There is average of 6.3 million new mobile subscribers in India e rattling month in 2006. Moreover, 43 percent of Asia- Pacific mobile market is belongs to China with a penetration rates of 35 percent.The purpose of this root word is to find out why there is a big gap between the mobile internet system of the joined States and Myanmar. Myanmar was chosen beca drill it has a very low mobile penetration level and Myanmar has only 9% out of 60 million people go for mobile phones.This research question get out emphasis on the distribution and segmentation of the medium in both United States and Myanmar, ownership, national restrictive structures, socio-economic origins and functions of mobile phones in todays society. main(prenominal) BODYDISTRIBUTION AND SEGMENTATION OF MOBILE NETWORK IN MYANMAR AND UNITES STATESDistribution of mobile network in MyanmarThe telecommunications sector in Myanmar is under developed. assure 2 shows that the mobile phone coverage serves just 10% of the universe in Myanmar. There are more than 55,000 villages in Myanmar are still without mobile service. The disposal targets to reach 75 to 80 percent of mobile penetration in 2016.Figure 3 illustrates that only 0.8 per 100 habitants have a mobile phone subscription in Myanmar.Distribution of mobile network in United StatesWhile in United States, the biggest mobile network provider Verizon had covers over 95% of the population by 4G LTE. Figure 4 illustrates the coverage of 4G LTE of Verizon in United States.There is a very big difference between the mobile network coverage of United States and Myanmar. Myanmar has a very low mobile phones penetration rates due to the poor mobile network coverage.Segmentation of mobile phones in MyanmarNandar state that two foreign firm Ooredoo and Telenor has tap in Myanmar has invested to improve their communication. While other province is enjoying the technology of cameras, trendiness and personalizing their own phone, Myanmar is still concern of their phone keyboard for Myanmar language.Maierbrugger tell that Myanmar is still the stage to expand their mobile services. Based on the latest statistic, stated that only 5.4 million of Myanmars 60 million populations have cadre phones. SIM cards used to be $160, but are now slowly being reduced with the help of foreign mobile companies.Segmentation of mobile phones in United StatesBased on comScore Networks research, their national panel survey concluded that there are three age-related segments. First is The Cellular Generation. They are older from 18 to 24 this generation was born with mobile phone awareness, growing up with mobile phones. Second age-related segment is called Transitioners. They are mainly aged from 25 to 34 because this group falls into two particular segments which are those who grew up with mob ile phone awareness and those who did not. Finally the third group is known as Adult Adopters. This group is aged 35 or older and they are not aware of phone until adulthood. They showed the least interest in emerging technologies.Figure above showing the result for cell phone attitudes by consumer segment for the year 2006.OWNERSHIPOwnership of mobile networks in MyanmarThere are only two mobile network providers in Myanmar, they are the Myanma Posts and Telecommunications and Yatanarpon Teleport. The Myanma Posts and Telecommunications (MPT), is the main provider of telecommunication services in Myanmar. MPT is operating under the Ministry of communications, Posts and Telegraphs. In order to assemble the demand for data communication services for the business and IT industry, Yatanarpon Teleport (YTP) was established in September 2002.Song stated in International Business multiplication that MPT and YTP only cover less than 10 percent of the network coverage in Myanmar. In June 2 013, Qatars Ooredoo and Norways Telenor won contracts to develop the mobile network in the country. Chun and Mahtani stated in the Wall Street Journal that Ooredoo and Telenor will become the first foreign telecommunications operators in Myanmar. After decades of military rule in Myanmar, it welcomes the foreign investment to its once tightly controlled telecom sector by awarding the telecom licenses.Ownership of mobile networks in United StatesWhile in United States, there are 14 mobile network providers. The four main providers are Verizon Wireless, ATT Mobility, Sprint Corporation and T-Mobile US. Verizon Communications Inc., based in sunrise(prenominal) York City was formed on June 30, 2000, with the merger of Bell Atlantic Corp. and GTE Corp. ATT Mobility is a wholly owned subsidiary of ATT Inc. ATT provides wireless services to 109.4 million subscribers in the United States. Sprint Corporation is a major global Internet carrier and also provides wireless service. SoftBank Cor poration owned majority shares of the company. T-Mobile US, Inc. is an American wireless networks operator, headquartered in Bellevue, Washington. Deutsche Telekom AG maintains a 67% ownership of T-Mobile US, Inc. common stock.NATIONAL REGULATORY STRUCTURESSpectrum scarcity is the main regulatory issue arising from the mobile network markets. Regulators have to allocate the spectrum rights with care to ensure the growth and efficiency in the market. The mobile network markets of United States and Myanmar are different as they have different number of operators and regulatory structures.National regulatory structures in MyanmarThe Telecoms Law in Myanmar stated that access and interconnection provided by a licensee shall be on an equitable and non-discriminatory basis and shall not be of lower technical standard and quality than the technical standard or quality provided in the licensees own network facilities or network services. The regulator have the power to negotiate interconne ction with the licensees or even share the facilities that cannot be proficiently replicated. The interconnection agreement and the procedure for referring and result disagreement are being concluded when the draft regulations go on to specify period. However, it is unseen that how Myanmar practice these rules, but in writing Myanmar will have an international regime with other countries which are in best practice.The next concern is the public availability of licensing criteria. Myanmar had awarded two national mobile licences to Ooredoo and Telenor. The process was blossom and transparent with more than 90 bidders participating. In both the draft licensing guidelines and the law, the outline for the additional licences is clearly stated. The draft regulations had provided the licensing criteria, timeline and licence terms and it meet the requirements.National regulatory structures in United StatesIn United States, the mobile service started as a governing body-licensed duopoly with licenses extending over urban areas and later to rural service areas. The Federal Communications Commission (FCC) achieved this by transferring the 115 MHz of spectrum into mobile uses. There are many operators owned the licenses but soon consolidation happened within the industry by mergers and acquisitions. FCC gives the permission to Fleet Call, a new company to penetrate the market by selling the special mobile radio licenses and convert them to cellular use in 1992, because Fleet Call offered to make better use of the spectrum. Then, an advance mobile communication- Personal Communications System (PCS) was invented. The licences for PCS con only be obtained through a government auction.SOCIO-ECONOMIC ORIGINS AND FUNCTIONS OF MEDIUM IN TODAYS SOCIETYSocio frugal Origins in MyanmarEver since Ooredoo and Telenor invested in Myanmar, there are numerous benefits which the country obtained. The overall economic effect of mobile sector in Myanmar is estimated to increase by 1.5- 7.4 percent of gross domestic products (GDP) in the first 3 geezerhood after the licenses are issued. There will be an impact on the employment rate in Myanmar for mobile sector, estimated over 66,000 will be sedulous as full-time employees.Figure above explains both direct and indirect employment rate of mobile value chain. Productivity of workers increased for the past 3 years because of the effect of mobile communication. This is mainly caused by the information flow between seller and buyer, decrease in time for travelling, and the possibility to access in new areas in Myanmar. For example, agri burnish sector, fisherman or farmers could quickly be notified about the price change in the market so that they could alter their plans. It is forecasted that Mobile Network Operator (MNO) gives various benefits to the supply side of economy in Myanmar via the direct impact of their outflow.As for the social impacts of mobile phone in Myanmar, the growth of Myanmars community interpe rsonal and family communication will be improved. Moreover, isolated areas could be reached with the support of mobile phones. Hence isolation will be reduced.Socio Economic Origins in United StatesThe mobile phone sector for United States brought a deep impact in the economy. Figure 6 shows that United States mobile phone industry has created 3.8 million directly and indirectly. An increment of 200,000 employments and this could conclude that an increase of 2.6% of all US employment. Furthermore, the phone industry with its direct and indirect workers has paid over $88.6 zillion in taxes, as well as the federal, state and local fees. Moreover, mobile phone sector, it contributed $1.739 billion to US GDP from year 2011 to 2012. Moreover, an increase in government revenues as much $468 million and the employment rate also increased by 7,000.Figure 6 shows that the employment created by wireless industry in the United States in year 2011.Function of medium in todays societyThe mobile phones clearly shows the priorities and values of our culture. Firstly, the mobile phones reveal the culture of constant communication. It is important for todays society to stay connected with their family, friends and colleagues. People are able to call anyone with a mobile phone no matter where it is except for those areas that do not have mobile network coverage.Another concern of people purchase mobile phones is for safety reason. Mobile phones keep open people feeling safe through being connected. Imagine individual stuck on a dark road with an empty gas tank or a flat tire and the person does not have a mobile phone to ask for help. The person might have wait for someone that pass by or start walking in the dark. Besides, this is a dangerous world, anything could happen. A mobile phone is needed for us to get help when we need it most.Another cultural priority of todays society is reflected by the mobile phones, which is technology. We are living in a society that always searching for the new and improved technology. Mobile phones was very big and clunky objects that got very poor reception and not reliable. And now it transformed to a mobile phones that able to fit in our pocket and have many technological abilities that are important to todays society.After all, mobile phones are really extremely important in todays society.CONCLUSIONThe purpose of this paper is to search for the reason why there is a big gap between the mobile network system of the United States and Myanmar. After the analysis, the main reason that the weak mobile network system in Myanmar is because of the military has the control of the whole telecommunications system. Myanmar did not open to other countries to invest in the telecommunications sector until 2013. However, the main concern of people getting a mobile phone is to look for safety, status, or service. twain United States and Myanmar need to invest in its infrastructure with proper regulatory measures to ensure they the people in the country could enjoy the best facilities.

An Introduction To Encryption And Decryption

An Introduction To encoding And decodingCHAPTER 1This thesis proposes a VHSIC ironw are Description Language (VHDL) design of Encryption and decoding algorithmic ruleic rule for Data. In this chapter, the challenges of cryptography is firstly presented. This chapter also briefly discusses the some(prenominal)er definition, scope of work and the thesis objectives are also highlighted.Finally, the chapter end with the chapter organization. The dissertation presentation is provided at the end1.1 An introduction to Encryption and Decryption, a type of cryptographyEncryption and Decryption, a type of cryptography, refers to the do work of scrambling information so that the observer cannot be signal detection the data. cryptographic observe is a piece of data customd to encrypt or decrypt to plaintext. (Alex Brennen V., 2004) The Crypto, from the record crypto logical system mean is it has its origins in the Greek word KRUOTOS, which means hidden. Thus the objective of cryptogr aphy is to hide information so that only the intended recipient can read it.2 . Cryptographic is a protocol or method of performing encryption and decipherment (Alex Brennen V., 2004). There are two types of cryptographic cruciate and a bilateral key. Figure 1.1 is example a radiate cryptographic has a single key, which is used for both encrypting and decrypting information. Data Encryption and Decryption is a well-known example of bilaterally symmetrical cryptographic. In symmetric cryptographic, public-key cryptographic uses complementary pair of keys to divided the process of encryption and decryption. This process is shown in Figure 1.2. This part is discuss about the symmetric-key cryptographic only.3.

OverviewThis chapter is to introduce the host range of background information and research for this thesis. Most methods have been widely used to determine how the process of encryption and decryption.Theoretical method is presented using the VHDL. Chooses the VHDL programming for design encryption and decryption because this programming is very direct forward is compare other programming. For example Cadence and C++ programming. Both programming is very complicated.In this chapter, the Literature review of the research is discussed. The main topics discussed in this chapter are shown belowSymmetric cryptographyEncryptionDecryptionOperations of Encryption and DecryptionData Encryption and DecryptionVHDL (VHSIC Hardware Description Language)2.1. Symmetric key cryptographyThe symmetric key organisation is the conventional method of cryptography. T he scheme uses the similar key to encode and decode in information. In a symmetric key algorithm, in the normal case, the communication only uses only one key. For example if Z user Z sends the secret symmetric key to an X user before the start of the communication between them. Part Z and X use the same symmetric key to encryption and decryption the message. Encryption and Decryption are example of symmetric key algorithm. Figure 2.2 shows the symmetric key cryptography. The symmetric key algorithm is straightaway than an asymmetric key algorithm. There are two classes of symmetric key cryptography as block ciphers and stream ciphers. 6Plaintext XPlaintext ZEncryption and DecryptionSymmetric KeyFigure 2.1 The symmetric key cryptography2.2 Block CipherBlock cipher is a type of symmetric-key decryption and encryption algorithm. The symmetric-key decryption and encryption that is a fixed length block of plaintext data into block ciphertext data. The block size is 64 bit. The block si ze can be mounting to 128 bit, 256 bit or 512 bit if the process becomes adforefrontced. Block ciphers operate on large blocks of data. The encryption and decryption of plaintext with a block cipher forget result in the same when the same key is used. From the figure 2.3, it can be seen that show the Block CipherPlaintextPlaintextBlock Cipher Encryption and Block Cipher DecryptionSymmetric KeyFigure 2.2 Block Cipher2.3 bourgeon CipherStream cipher is a type of symmetric encryption and decryption algorithm. Stream ciphers much faster than any block cipher. Stream ciphers operate on smaller units of plaintext. The encryption and decryption of plaintext with a stream cipher forget result in the same when the same key is used. From the figure 2.3, it can be seen that show the Stream CipherPlaintextPlaintextStream Cipher Encryption and Stream Cipher DecryptionSymmetric KeyFigure 2.2 Stream CipherAdvantages of Symmetric Key CryptographyThe main advantages of symmetric key (public key) cryptography are improved warrantor and expediency.Other major advantages from the symmetric key (public key) are that they can provide a technique for digital signatures. Verification via secret-key system requires a shared secret and sometimes requires trust of a third party.For example, Kerberos verification system involves a button-secret data center that stores copies of all user secret key. An blow on the database will enable the falsification of the system. Public key verification, on the other hand, prevents of rejection, and each user has a responsibility to protect his private key. 72.3 Disadvantages of Symmetric -Key CryptographyThe disadvantage of symmetric cryptography is that it presumes two parties have agreed on a key and been able to exchange that key in a secure manner prior to communication. This is a significant challenge. Symmetric algorithms are usually mixed with public key algorithms to obtain a blend of security and speed.Disadvantage of using symmetric-k ey cryptography for encryption and decryption is faster. There are popular secret-key encryption and decryption technique that are considerably faster than any at present available symmetric-key encryption and decryption technique.However, public-key cryptography can be used by means of secret-key cryptography to obtain the optimum of both worlds. For encryption, the optimum solution is to join together with public-key and secret-key systems in order to obtain both the security advantages of public-key systems and the velocity advantages of secret-key systems. The public-key system can be concord use of to encrypt a secret key which is make use of to encrypt the bulk of a information or message.Public-key cryptography may be open to impersonation, although, also further much if users private keys are not available. A successful assail attack pounce on a certification authority will permit a national foe to impersonate whomever the adversary pick out to by using a public-key certif icate from the compromised authority to bind a key of the national foe choice to the name of another userIn some plight, public-key cryptography is not obligatory and secret-key cryptography alone is enough. This be to environments where secure secret-key assent can take place, for example by users confluence in private. It also belonging environments where a sole authority knows and manages all the keys. formerly the authority knows everyones keys already there is not much excess for some to be public and others private. And yet, public-key cryptography is normally not obligatory in a single-user environment. Example, if want to keep private message or information encrypted, can do so with any secret-key encryption algorithm using personal password as the secret key. Furthermore, public-key cryptography is optimum equivalent for an open multi-user environment. Public-key cryptography is not intention to substitute secret-key cryptography, but nevertheless to complementary it, to make it more safety 82.4 EncryptionEncryption is a form of cryptography that to change the plaintext into ciphertext. A cipher is a algorithms for the encryption. Encryption is the principle of such security step as digital signatures, digital certificates, and the public key infrastructure. Computer-based encryption method use keys to encrypt and decrypt information. A key is in binary number. The key is one part of the encryption process. It must be used in connection with an encryption algorithm to generate the cipher text. Encryption is the symmetric or asymmetric. Ciphers were repeatedly used directly for Encryption without supplement procedures such as ratification. The extremely used material body of encryption is symmetric Encryption, which is aptly named for the intellect that it uses one key for both the encryption and decryption system 92.5 DecryptionDecryption is the opposite or moving from the ciphertext back to the plaintext. A cipher is a algorithms for the decryp tion. The specification operation of a cipher is to manage with both by the algorithm and in each example by a key. Decryption is the symmetric or asymmetric. Ciphers were repeatedly used directly for decryption without supplement procedures such as ratification. The extremely used kind of decryption is symmetric decryption, which is aptly named for the argue that it uses one key for both the encryption and decryption system 10.2.6 Operations of Encryption and DecryptionAn encryption and decryption scheme consists of three Standard algorithmsA Key Generation Algorithm. For a symmetric key, this is often an algorithm that simply picks a random key of a certain length. The symmetric key scheme is the conventional method of cryptography. The scheme uses the similar key to encode and decode in information.An Encryption Algorithm. This takes as input a message (or plaintext) and some kind of key, and outputs a ciphertext. Encryption is to change the plaintext into ciphertextA decryption algorithm. This takes as input a ciphertext and some kind of key, and outputs a message.Decryption is to change the ciphertext back to the plaintext2.7 Data Encryption and DecryptionThis system works by encrypting and decrypting groups of only 64 message bits, which is the same as 16 hexadecimal number. To do the encryption and decryption, this system uses symmetric keys where are also apparently 16 hexadecimal number long, or 64 bits long. However, every 8th key bit is ignored in this algorithm, so that the effective key size is 56 bits. But, in any case, 64 bits (16 hexadecimal digits) is the round number upon which Encryption and Decryption is organized.The process is explain in Figure 1.2, it can be seen that the process of encrypt and decrypt, if take the plaintext message is 2872762F771B15E8, and encrypt it with the key 0000000000000001, the ciphertext produced 1234567890987654.

Device description language VHDL is a great acronym stands for the Very utmost Speed Integrated Circuit Hardware Description language. It was originally developed on the orders of the U.S Department of Defense. They need a more efficient way to text file the behavior of the ASIC design service companies were present.11,12 It was developed as an alternative to the huge, highly complex manuals that were the norm. The idea to simulate such a description was immediately an attractive prospect and logic simulators were developed could take a VHDL description as input. From here synthesis to the hardware level became a focus of study and still is. Current state-of the- art synthesis tools can create hardware for a large subset of the VHDL language and should at least support the synthesizable subset in IEEE1076.6-1999. The syntax of VHDL was derived from Ada, with constructs added to handle the parallelism that appears in hardware designs. The language is strongly typed and case insensitive. 13,14 The initial recitation of the language that was presented in the IEEE standard 1076-1987 was roughly limited and a new version appeared in 1993 in IEEE standard 1079-1993, which improved the consistency of the language. There have been various reviews and updates to the standard of the languages since, but the 1993 version is the most prominent and widely used. Both versions of the language ignored the need for a multi-valued logictype which is where the IEEE standard 1164 comes in.15 This standard defines a 9-valued logic type called standard logic. This has become the standard type to use for multi- valued logic in VHDL descriptions. The language has been further extended in a series of libraries. One such library is the numeric std library which implements a signed and unsigned type. These types allow for arithmetic to be performed on arbitrarily sized logic vectors. 162.4 VHDL (VHSIC Hardware Description Language)In order to complete the design, the VHDL is one of the most important tools used.

Misconceptions of psychology

Misconceptions of psychologyNumerous studies pee shown undergraduate students and everyday people to have a range of misconceptions about psychology. This study examined misconceptions among cardinal group of first form psychology students, and an otherwise group of first year design students in order to determine whether psychology students perform importantly better than students of other academic disciplines in regards to their cognition of psychology. A quasi-experimental mugwump-groups design was utilise, with the independent proteans in this study having ii levels, or whether the participant was either a psychology or engineering student and the dependent variable of the number of emend incertitudes the individual achieved on the questionnaire. Results of this study showed that students from the two disciplines differ in their misconception and knowledge of psychology, with descriptive statistics and analyses of an independent groups t- discharge and a point biserial correlation showing a significant exit betwixt the two groups. Conclusively, this study suggests that psychology students do have fewer misconceptions comp ard to engineering students, while advance stating an alternative explanation and criticall(a)y analysing procedures used to determine the produced provides. Further research of in this area could focus on proveing the misconceptions of a more varied taste, administer a different type of questionnaire, while also extending much(prenominal) research to a range of groups such as psychologists, doctors, teachers, or students of numerous disciplines.Misconceptions of psychology A comparative study between psychology and engineering studentsPsychological research, regardless of the specific topic of study, is found upon the same scientific principles as the other hard sciences like physics and chemistry. Nevertheless, psychology has a long history of fighting a commonly held cognition that it does not qualify as a scientific discipline and that it generates knowledge that is mere common sense. In galore(postnominal) cases, however, common sense leads to an incorrect savvy of phenomena that have been scientifically investigated by psychologists. Several studies have shown that undergraduate students and lay people alike hold many misconceptions about psychology. These misconceptions have been demonstrated in the United States and England and in several(prenominal) different courses of study.McCutcheon, Furnham, and Davis (1993) asked if there was a significant difference in the prevalence of misconceptions about psychology between American and side university students. They administered a 65 item multiple-choice questionnaire and found that English students principally did better than American students, though neither group answered more than half of the questions correctly. magic spell the authors offered no clear explanation for either the poor performance or the difference between the two groups, they speculated that selective reporting in the mass media may contri simplye to two the formation of misconceptions and their resolution.Martin, Sadler, and Baluch (1997) adjudicateed undergraduate students from psychology, sociology, business, English and engineering from Middlesex University, U.K. on their general knowledge of psychology. Questions on their test invited common sense but incorrect answers. Out of a possible score of 38, psychology students scored highest with an average score of 17.08 while engineering students scored lowest with 11.57. Martin et al. also found that engineering students were least likely to regard psychology as adept of the hard sciences or even one of the social sciences.The present study followed up previous reports of students generally poor performance on tests of misconceptions about psychology. Specifically, we repeated a portion of Martin et al.s (1997) study of misconceptions about psychology. We tested two Australian undergraduate cla sses, one anterior psychology class and one introductory engineering class, on a true/false test of common misconceptions about psychology adapted from scoop out (1982).This way of replicating a study is known as conceptual replication. While not all details of the Martin et al. study were replicated, this study allowed researchers to answer the overall question of misconceptions in psychology from a different angle. For this to be considered an exact replication of the Martin et al. study, misconception tests should have been given to individuals from a range of both first and last year psychology, sociology, business studies, engineering and English students, compared to just first year psychology and engineering students. Additionally, this study did not use a multiple choice test of misconception, but rather assessed misconception utilize a true or false questionnaire and provided no questionnaire of student attitudes towards psychology.The present study aimed to determine wh ether psychology students perform significantly better than students of other academic disciplines in regards to their knowledge of psychology. It was hypothesized that psychology students would have the lowest number of misconceptions about psychology, while engineering students would express the near misconceptions. ruleParticipantsThe 641 participants in this study consisted of 282 first year, undergraduate psychology students and 359 first year, undergraduate engineering students. Of the two groups in the study, the psychology group consisted of 75 males and 207 females, with ages ranging from 16 to 59 days, and a intend age of 20.3 years and a standard deviation of 5.5 years. The engineering group consisted of 264 males and 95 females, with ages ranging from 16 to 59, and a mean age of 20.0 years and a standard deviation of 5.3 years. The experiments were conducted at a university during Week 2 tutorials in the second half of the university year. Students were recruited by means of whether they were enrolled in either PSYC1040 or ENGG1000, two courses offered at the university.Design and MaterialsFor the present study, a quasi-experimental independent-groups design was used. Similar to a true experiment, this study set up two levels of the I.V. (independent variable) and measured its consummation on the D.V. (dependent variable). In this case, formation of the two groups was established by random assignment, but also by criteria established prior to completing the study. The independent variable in this study had two levels, or whether the participant was either a psychology or engineering student, while the dependent variable was the number of correct questions the individual achieved on the questionnaire. The key difference in a quasi-experiment is that participants in this study were tested on their knowledge and misconceptions according to characteristics they already acquired.The experiment used a 36-item true or false questionnaire (see Appendi x A) to measure participants misconceptions and knowledge about psychology. The statements were drawn from a previous study conducted by Best (1982), which additionally suggested these statements appeared in a range of contemporary psychology textbooks and other similar questionnaires. Each statement consisted of a short sentence describing a simple scenario or event (e.g. psychiatry is a subdivision of psychology) and for which each participant was instructed to provide a true or false answer.ProcedureAll 641 participants received one copy of the questionnaire. Individuals were given the questionnaire during tutorials in Week 2 of Semester 2, 2010. Members of each tutorial group were assigned randomly by means of being there at the given time. Participants were instructed to complete each item individually and answer the statement as honestly as possible. The questionnaire was completed individually by the participants, without any fundamental interaction with fellow colleagues. P articipants were given 10 minutes to fill in their answers, after which they were asked to swap their questionnaires with the person sitting next to them. Each participant then counted how many of the answers were correct and wrote down a score out of 36. For all the questions, the answer was false. Questionnaires and tally for both PSYC1040 (see Appendix B, figure 3) and ENGG1000 (see Appendix B, figure 4) were collected for further analysis and publication of the raw data.ResultsData for both groups was explored graphically through frequency tables, frequency polygons, and box-and-whisker plots and were statistically analysed by means of an independent groups t-tests and a square up point-biserial correlation coefficient.Table 1. Mean questionnaire score and standard deviation of PSYC1040 and ENGG1000Descriptive StatisticPsychologyEngineeringMean20.67412.262Standard Deviation5.2464.030Psychology students scores were the high of the two groups, with a mean of 20.7 and a standard deviation of 5.25 (see Table 1). Engineering students, on average scored lower than psychology students, with a mean of 12.3 and a standard deviation of 4.0 (see Table 1). As further indicated in Appendix C, psychology students performed better, with clear indication scores ranged between 16 and 26, while the engineering students highest scores ranged from 9 to 18 correct answers. Relative frequencies (see Appendix C, tables 4 5) were greater for scores between 15 and 28 for the PSYC1040 group, while scores between 8 and 18 for the engineering students proved to be more relatively frequent. Similarly, Figures 2 and 3 (Appendix D) illustrate PSYC1040 participants to have performed better than ENGG100 students, as psychology students achieved a high score of 20 (indicated by the peak in the graph) most frequently and compared to engineering students who achieved a high score of only 12 most frequently. Additionally, from the distribution illustrated, the highest score from the PSYC 1040 group was 36, while the lowest score was 6. Contrastingly, engineering students performed worse, achieving a high score of 30 and a low score of 0. Systematically, psychology students scores (See Appendix E and Appendix G, Figure 5), showed a mode and median of 20 and a range of 30. Descriptive statistics (Appendix E) and the box and whisker pomp (Appendix G, Figure 6) for the engineering group indicate a mode of 11 and a median of 12, while the range proved to be 30.Descriptive statistics (Appendix E) for the two groups show a significant difference between the two groups. Psychology students in fact performed 8.41 points greater than engineering students. However, in order to obtain a difference which is statistically important, certain assumptions were made to in order to perform further statistical analyses. Three assumptions were made of the independent groups t-test performed. Firstly, it was assumed that scores of PSYC1040 were independent of scores by ENGG1000 students , that data collected is representative of normally distributed populations and that dissonances of the two groups scores are alike. Test scores of PSYC1040 can be assumed to be independent of test scores of ENGG1000, as individual test scores from PSYC1040 could in no way be related to test scores achieved by ENGG1000 students, as the two groups were different. By means of illustration using the frequency polygons (Appendix D), the second assumption can be proven correct. While the two distributions of the sample look more skewed and peaked than a normal ideal curve, we can make a decision that indeed the two samples of scores are from normally distributed populations as distributions of scores are not too skewed or peaked to violate such an assumption. Variances of the two populations differ close to, as variance for the psychology group was 27.525 and variance for the engineering group was 16.243. There is no great difference to assume the two differ, so as a result we accept t he given data and proceed.An independent groups t-test (see Appendix H) revealed that psychology students (M = 20.67, SD = 5.25) performed significantly better than engineering students (M = 12.26, SD = 4.03), with t (639) = 22.92, p DiscussionAs predicted, psychology students performed vanquish in the misconceptions of psychology test than engineering students. The independent t-test and point biserial correlation both support the hypothesis proposed. The independent t-test showed significance between the two groups. The difference is very unlikely to occur if the samples were of no difference in the population and as a result the assumption is rejected. In other words, we reject the nil hypothesis () and accept the alternative hypothesis, or that we are accepting a difference between the means that is no equal to zero. In this case the mean for psychology test scores is larger than the mean for engineering test scores, so it can be concluded that studying psychology leads to sig nificantly higher tests scores when it comes to misconceptions of psychology.Additionally, the squared point-biserial correlation coefficient also supports the predicted hypothesis. Indicating the proportion of variance in a two sample study, the proportion ranges from 0 (variable has no effect) to 1.0 (variables pick up scores and therefore 100% of all scored can be predicted accurately). Variables representing between 10% and 30% of variance, indicated a relationship. Therefore, it can be concluded that being an engineering or psychology student accounts for a significant amount of the variance in the test scores. The variable therefore plays an important part in determining the test scores on the misconceptions survey. This means that the study was significantly more accurate at predicting a participants knowledge of psychology by knowing the condition they were in as opposed to just utilising the overall mean score for both conditions.Alternatively, composition of the two class es may have affected the data obtained. In both classes a sex difference exists. The psychology group consisted of more females than males, while the engineering group consisted of more males than females. Uneven numbers of males and females allows the data to be slightly bias. While experimental logic states that if one variable is manipulated, and if everything is kept the same, then all differences we observe are due to the manipulation of that variable. Quasi- experimental studies, which use gender as a variable, cannot be easily manipulated, meaning we cannot change gender throughout the experiment and we cannot be sure everything else stays the same. In order to control for the factor of gender bias, it is important to ensure the samples are representative of both males and females, in both the psychology and engineering groups. Possibly, other types of groups could be tested, all of which should be representative of both genders.McCutcheon (1991) critics the questionnaire us ed in this study. The Test of Common Beliefs has been constantly criticised on the basis that many items are ambiguously written. It has been argued that making the correct answers to all items false exposed individuals to accept without protest and gives many the opportunity to guess the answer by chance. Furthermore, McCutcheon suggests, items on several misconception tests are not widespread, meaning the test only focuses on a specific set of topics. Several studies such as Vaughan (1977), Lamal (1979), Gardner and Dalsing (1986) and Griggs and Ransdell (1987) all found that only a fraction of their questionnaire items were answered and only by half of their participants. It is possible to come to the conclusion that students which are beginners in psychology do not have many misconceptions about the subject. McCutcheon also proposes a scuttle that true-false surveys are perhaps not the best at measuring misconceptions. In order to counter for this, McCutcheon steers away from u sing the true-false test of misconceptions, including several questions related to participant interest.Overall, results of this study suggest that in fact psychology students do have fewer misconceptions about psychology. It may be that other students of other disciplines are not aware of the knowledge required to overcome such misconceptions and therefore may even dismiss psychology as being a hard science. Further research in the area could include a study of misconceptions based on a larger, varied sample, while also using a questionnaire related to participant interests instead of a true or false questionnaire. Furthermore, future studies could also integrate participants who may be more see in the field, such as qualified psychologists in order to further analyse inter-disciplinary comparison of attitudes about psychology.

Will we see the Downfall of Nintendo? Essay example -- Video Game Ind

Lets go back in time for a moment and recapture the epic crash to the icon feisty pains in North America that took place in 1983. There was a flood of bad games that shrunk the games industrys value from three billion dollars subjugate to a few hundred million. The Atari 2600 system was pretty much the basic and most populated console in the states in the early 80s. Atari was mainly prudent for its lack of productions and marketing. Even the Commodore 64 and the ColecoVision had its share of failed productions along with many other brand consoles. Eventually consoles and game cartages became were sold at bargain discounts. This was great for customers non at all for the industry and the developers. Arcades were the tho successful outcome the industry had but soon enough everyone was about to see the death of the video game era. While Atari failed to recover a small Japanese trading card and toy company rose to the occasion in the states and began marketing the greatest syndic ate console as we know of today, the Nintendo Home Entertainment System. Although Japan struggled to get North America to market the Nintendo system, Japan featured now and more fire ways to play video games using the Zapper, ROB the Robot, story lines and saving data that couldnt compare to how we used to play in the arcades.

The Supernatural in Shakespeares Macbeth :: GCSE English Literature Coursework

Use of the Supernatural in Macbeth Shakespeares Macbeth has many supernatural actions. Although both of supernatural do not have exactly same role in the play, the main purposes of supernatural are to attract the attention from audience manipulation, to presage future events, to show the characteristics of individual, and to connect the idea with theme. In the play, the supernatural occurs witches appearance throughout the story, the strange behavior of Macbeth after the murderer of King Duncan, the situation of genius in Scotland, appearance of Banquos ghost and imagination of dagger which was flying in the air. Firstly, the story starts with weird sisters conversation under strong thunder and lightning. It is real effective way to attract the attention from audience First Witch says with scary voice, When shall we three meet again, In thunder, lightning, or in rain ? (I, i, 1-2) The truly first scene is not only winsome, but also there is an important clue for the things to be happened in the future foreshadowing. We learn that there is something personnel casualty to happen with Macbeth Macbeth wins for his life, but he also is going to lose for his life There to meet with Macbeth (I, i, 7) Fair is foul, and foul is fair. (I, i, 11)The speech of Witches also contains a theme. When angiotensin-converting enzyme wins, one must lose is a possible theme that can be taken from the speech When the battle is lost and won (I, i, 4) The witches continue visual aspect throughout the story to give us the excitement, hint and theme. Secondly, Macbeth loses his mind after the killing of King Duncan. Is it attractive ? By considering the situation, it can be said that it is attractive When he reenters into the play after killing of Duncan, he is a completely different man, like a stone. We must be surprised that if Macbeth is standing up with bloody face, bloody swords in his hands and talks something that does not make senses at all Why did you bring these daggers from the place ? (II, ii, 48) It also shows characteristics of Macbeth. Macbeth can considerably fall into a confusion that he cannot recognize. Thirdly, later in the story, Macbeth sees the Ghost of Banquo and the dagger in the air. However, the Ghost and dagger are only visible to Macbeth, and no one else is able to
