Discuss expectancy effects in research

Psychological experimentation is a process aimed to prove that certain types of behavior are predictable under particular situations or treatment conditions. These treatment conditions are manipulated in such a way that the setting created by the experimenters will invoke participants to display behavior towards the independent variable in regularity. This, in turn, will verify the experimenters’ hypotheses regarding the behavior in question. Hence, through experimentation, causal inferences between the independent and dependent variables can be reached.However, experimentations do not always go as planned. There are times when experimenters overlook various factors that may wrongly or unnecessarily affect the results of the experiment. These factors are known as extraneous variables, variables that are not the main focus of the study yet may produce variations in behavior. When extraneous variables become frequent and change systematically across different conditions of an ex periment, results can be confounded. One of the more popularly known consequences of extraneous variables is the Placebo Effect.Hansen and Myers (2002) explain that this is a type of social extraneous variable wherein participants react to the independent variable according to how they expect the independent variable to affect them (p. 196). Since the behavior of the participants is based on their expected effects, changes that occur may less likely be due to the independent variable. This indeed lowers the internal validity, thereby causing the results of the study to be invalid and inaccurate.In other circumstances, the experimenters are exactly the ones creating venues for extraneous variables to affect experimentations. Like the Placebo effect’s consequence, Experimenter Effect decreases internal validity in such a way that the extraneous variable causes changes in the dependent variable, not the independent variable of the experiment. This happens when the experimenters behave in a certain manner when dealing with participants (Hansen & Myers, 2002, p. 198).This may trigger participants to respond in a particular way between or among treatment conditions in order to fulfill the experimenters’ non-verbal cues. Fortunately, this effect may be controlled through a method called Double-blind experiment, say Hansen and Myer. This technique—when combined with consistency of instructions and processes, and objectivity of observations—can prevent the decrease in internal validity for both the experimenters and participants are not aware or are â€Å"blinded† with regard to the treatment condition they are handling or partaking, respectively (2002, p. 02).Since both parties have no idea on the nature of the treatment conditions they are assigned to, no bias or extraneous variables shall therefore arise and results produced shall be correct. For instance, it is deemed that caffeine keeps individuals alert and awake. This may be fu rther tested through an experiment, with a hypothesis which states that caffeine can improve night driving for tired drives.The independent variable here is the presence or absence of caffeine in the coffee drank by the participants while the dependent variable is their performance in a car-racing video game, specifically their recorded speed after three laps. In order for both the experimenters and the participants to respond without bias, the Double-blind Method can be applied. Given that coffee does ward off drowsiness and stimulate attentiveness, what remains to be critical is the effect of caffeinated or decaffeinated coffee on performance.Since the participants do not actually know if the coffee they are to drink has caffeine in it or not, they cannot behave based on what they think is expected from them. Likewise, the experimenters shall not be able to give indications or implications regarding the nature of the treatment condition the participants are in since they are also unaware of this. Thus, if the participants performed better subsequent to drinking caffeinated coffee or vice versa, experimenters will be sure that the presence or absence of coffee is responsible for this and not an extraneous variable.

Crime in uk - Essay Example The root cause of cult of celebrity is the deep-seated human desire to appear inspirational, famous and strong to lead ordinary people and attain personal satisfaction and fulfillment for belonging in the class of celebrities (Walker and Smith 2002). According to social identity theory, people identify themselves by their social groups which they belong and judge others by the memberships to the groups. Celebrity worship originated in 1880s since inventors, scholars and political leaders were perceived as cultural heroes and people were celebrated for being famous in the society (Walker and Smith 2002). Accordingly, the emergence of mass media technologies in 1920s and popularity of the entertainment industry shifted the cult of celebrity from character of the individual to personality of the individual (Walker and Smith 2002). Another factor that contributed to the popularity of cult of celebrity was the decline in morality due to decline in organised religion. These fixations of public personality distort the behaviour of individuals since millions are obsessed with famous celebrities such as Nicole Kidman and Tom Hanks (Walker and Smith 2002). A survey conducted among teachers in primary and secondary schools in UK concluded that cult of celebrity was affecting children’s expectations and aspirations in life since many teachers believed that their children want to be famous (Rojek 2001). The cult is producing a younger generation that believes educational achievements and hard work are not essential in attaining success in life. In this case, children will grow up with low self-esteem, sense of failure and alienation due to relative deprivation. Children idolise themselves with popular celebrities such as football stars, popular musicians and actors. The cult of celebrities is a widespread obsession, worship and idolatry on

Jazz documentaries, racism and segregation Essay

Jazz documentaries, racism and segregation - Essay Example One of most popular documentaries on Swing Jazz was released during 2000. The name of this documentary was Jazz and directed by Ken Burns. This documentary was broadcasted in a series of 10 episodes and offered information regarding the chronological history of jazz and its prominent musicians. The documentary studies various aspects of  jazz,  including drugs and  racial segregation (Burns, 2000). Racial segregation was one of the most serious issues during the peak popularity of Swing Jazz. Although, the Black community had contributed greatly in World War I and II, the society continued to discriminate against them. Even in jazz, the musicians as well as the audience during a jazz performance  was  seated separately.   â€Å"Due to the racism found in many states, clubs throughout the country were often segregated. Just a few bands were racially mixed, of which Benny Goodman’s was possibly the first† (Swing and Racism, 2015). Part 7 of documentary and chapter 18, â€Å"These Things cant happen† offers bleak information about the Black soldiers, who fought to defend the ideals of their country, liberty and equality. Swing and Racism observes: â€Å"Hollywood films handled the race issue by including the African-American swing jazz band performances in films such a way that these sections could be easily removed from the movie reels that were to be distributed to Southern States without disturbing the storyline† (Swing and Racism,

Minnesota Curriculum Integration Assignment Example | Topics and Well Written Essays - 500 words

Minnesota Curriculum Integration - Assignment Example The faculty and the advisers are keen in the undergraduate curriculum since they work under the set and existing structures (Thurlow, 50). One of the structures that are emphasized a lot is the academic planning for the student in addition to the issues that face the student when studying. The executive leadership plays a major role in teaching the faculty and advisers on how they can study abroad and still emphasize student to partner with them abroad. Since the institution is interested in long-term impacts through the transformation in the undergraduate curriculum, they work for it through structures that are followed by the advisers, faculty and the learners (Nussbaumer, 40). They still work to ensure that they can get the behaviors concerning the student studying abroad and how the institution will be depicted internationally. The executives of the institution are administrators, vice chancellors, vice provost, vice president, the directors and core curriculum team. They work together to make sure that the goals set are achieved within the stipulated time (Mitton, 45). For the purpose of curriculum integration, the institution follows the principles set in along with discipline that is equipped to the learners. The set structures which exist are part and parcel of the institution model where they are followed to make sure that the student will benefit and study abroad without fear. One of the goals of Minnesota curriculum integration is to make changes in the institution, making sure that innovation is achieved where they are going to partner with others. Additionally, the goal of curriculum integration is to make sure that faculty or the advisers that are in abroad create well-educated learners and global citizens that will contribute positively in the national development (Hallinger, 32). Another goal is to make sure more increased scholarship abroad is achieved.

Health care marketing - Essay Example Additionally, the health care institution should work to maintain a good brand name among the locals. The primary aim of this factor is to capture the external environment, which consists of the patients. This offers the health institution with an external insight of its brand in terms of marque image, brand personality, and brand familiarity.  Furthermore, the health facility should take into account innovation as a major factor for its marketing strategy. Innovation should take place in all departments of the hospital. This will increase the overall margins of the health facility and develop a new mindset to its patients. Secret shoppers or mystery shoppers are people hired by other rival organizations or business to spy on the progress of another business entity. The familiarity of secret shoppers is not common in many organizations since organizations set their own targets to achieve as opposed to benchmarking with other rival businesses. Mystery shoppers are popular in healthcare institutions equally to other business. This is because they aim to evaluate how healthcare is delivered in healthcare organizations and aim to correct important information and procedures that can be adapted in rival healthcare

Methods to measure gene expression in mammalian cells in vitro and in Essay

Methods to measure gene expression in mammalian cells in vitro and in vivo - Essay Example This method is based on suppression PCR technique that is a combination of normalization and subtraction in one procedure. The normalisation technique would equalize cDNA abundance in the target population while the subtraction step excludes the sequences that are common between the target and driver populations. 5 The two type of real – time PCR are the molecular beacon and SYBR Â ® Green method. SYBR Â ® Green method is the first method that was used in real – time PCR wherein it binds to double – stranded and when this would get excited, would emit light. On the other hand, molecular beacon utilizes a reporter probe that is wrapped to the hairpin.9 Involves mRNA isolation and hybridisation. mRNA is extracted and purified from the cells. To proceed with electrophoresis, mRNA is loaded to the gel. The current is allowed to pass through the gel and mRNA will move away from the negative electrode. To visualize mRNA, Flourescent dye is used as a stain followed by UV lighting. RNA is then transferred to a membrane from the gel electrically or through capillary action using a high – salt solution. RNA fragment that is in question is incubated with the blot and to remove the probe, the blot is then washed. Developmental step follows.10 A method to analyse comprehensively patterns of gene expression.8 mRNA is isolated from the sample. A small chunk of sequence is then extracted and these small pieces are sequenced together forming a long chain. These chains are cloned into a vector that can be taken up by bacteria. These chains are sequenced using a modern high. The data is then processed with computer in order to count small tags sequence.13 This method works at the 3 terminal portions of mRNAs by systemic amplification and resolution on DNA sequencing gel fragments. Primers are anchored and are designed to bind to 5 boundary of the poly-A tails for the reverse transcription.

Phonetics Case Essay Introduction The aim of this thesis is to give a systematic description of some aspects of English morphophonemic. The thesis falls into 2 chapters: The first chapter, which is an introduction, presents a short sketch of the title, the problem, the purpose of the study,phonological rules. The second chapter is devoted to some of the basic concepts required in the study of morphophonemic. It starts with various definitions of morpheme, allomorph. The thesis ends with some conclusions, a list of bibliography. Morphophonemic Analysis designates the analytic procedures whereby paradigms with phonological alternations are reduced to underlying representations and phonological rules. The term morphophonemic analysis has a now obscure origin. In the 1940s and 1950s, many phonologists worked with a theory in which (roughly) all neutralizing rules were assumed to apply before all allophonic rules. This in effect divided the phonology into two components: a neutralizing component, whose units were called morphophonemes, and a non-neutralizing component, which dealt with phonemes and allophones. This bifurcated-phonology theory is widely considered untenable today, but  morphophonemics remains a useful term for characterizing the study of neutralizing phonological rules as they apply in paradigms. When we conduct morphophonemic analysis, we seek to establish a connection between data and theory. The theory in question is that morphemes are stored in the lexicon in an invariant phonemic form, are strung together by morphological and syntactic rules, and are then converted to their surface forms by a sequence of phonological rules (often neutralizing), applied in a particular order. The purpose of morphophonemic analysis is to discover a set of underlying forms and ordered rules that are consistent with the data; and the payoff is that seemingly complex patterns are often reduced to simplicity. Morphophonemic analysis may be contrasted with phonemic analysis. Phonemic analysis is a more limited form of phonological analysis that seeks only to discover the non-neutralizing (allophonic) rules of the phonology. In phonemic analysis, only the distribution and similarity of the phones is examined. Therefore, the data need not be grouped in paradigms, but need only comprise a sufficiently large and representative set of words. Like phonemic analysis, morphophonemic analysis can be pursued with a systematic method. The main purpose of my work consists in making exact definition of a phoneme and allophone and be able to distinguish them. To understand what is morphophonemic?   Problems of my work are: morphophonemic and morphophonological rules, types of morphophonological changes, relation between phonology and morphophonology, isolation forms, rule ordering, morphophonology and orthography. Morphophonology (also morphophonemics, morphonology) is a branch of linguistics which studies the interaction between morphological and phonological or phonetic processes. Its chief focus is the sound changes that take place in morphemes (minimal meaningful units) when they combine to form words. Morphophonological analysis often involves an attempt to give a series of formal rules that successfully predict the regular sound changes occurring in the morphemes of a given language. Such a series of rules  converts a theoretical underlying representation into a surface form that is actually heard. The units of which the underlying representations of morphemes are composed are sometimes called morphophonemes. The surface form produced by the morphophonological rules may consist of phonemes (which are then subject to ordinary phonological rules to produce speech sounds or phones), or else the morphophonological analysis may bypass the phoneme stage and produce the phones itself. Morphop honemes and morphophonological rules When morphemes combine, they influence each others sound structure (whether analyzed at a phonetic or phonemic level), resulting in different variant pronunciations for the same morpheme. Morphophonology attempts to analyze these processes. A languages morphophonological structure is generally described with a series of rules which, ideally, can predict every morphophonological alternation that takes place in the language. An example of a morphophonological alternation in English is provided by the plural morpheme, written as -s or -es. Its pronunciation alternates between [s], [z], and [É ªz], as in cats, dogs, and horses respectively. A purely phonological analysis would most likely assign to these three endings the phonemic representations /s/, /z/, /É ªz/. On a morphophonological level, however, they may all be considered to be forms of the underlying object //z//, which is a morphophoneme. The different forms it takes are dependent on the segment at the end of the morpheme to which it attaches – these dependencies are described by morphophonological rules. (The behaviour of the English past tense ending -ed is similar – it can be pronounced [t], [d] or [É ªd], as in hoped, bobbed and added.) Note that the plural suffix -s can also influence the form taken by the preceding morpheme, as in the case of the words leaf and knife, which end with [f] in the singular, but have [v] in the plural (leaves, knives). On a morphophonological level these morphemes may be analyzed as ending in a morphophoneme //F//, which becomes voiced when a voiced consonant (in this case the //z// of the plural ending) is attached to it. This rule may be written symbolically as: /F/ - [ÃŽ ±voice] / __ [ÃŽ ±voice]. In the International Phonetic Alphabet, pipes (| |) are often used to indicate a morphophonemic rather than phonemic representation. Another common convention is double slashes (// //), as  above, implying that the transcription is more phonemic than simply phonemic. Other conventions sometimes seen are double pipes (|| ||) and curly brackets ({ }). Types of morphophonological changes Inflected and agglutinating languages may have extremely complicated systems of morphophonemics. Examples of complex morphophonological systems include: 1. Sandhi, the phenomenon behind the English examples of plural and past tense above, is found in virtually all languages to some degree. Even Mandarin, which is sometimes said to display no morphology, nonetheless displays tone sandhi, a morphophonemic alternation. 2. Consonant gradation, found in some Uralic languages such as Finnish, Estonian, Northern Sà ¡mi, and Nganasan. 3. Vowel harmony, which occurs in varying degrees in languages all around the world, notably Turkic languages. 3. Ablaut, found in English and other Germanic languages. Ablaut is the phenomenon wherein stem vowels change form depending on context, as in English sing, sang, sung. Relation between phonology and morphophonology Until the 1950s, many phonologists assumed that neutralizing rules generally applied before allophonic rules. Thus phonological analysis was split into two parts: a morphophonological part, where neutralizing rules were developed to derive phonemes from morphophonemes; and a purely phonological part, where phones were derived from the phonemes. Since the 1960s (in particular with the work of the generative school, such as Chomsky and Halles The Sound Pattern of English) many linguists have moved away from making such a split, instead regarding the surface phones as being derived from the underlying morphophonemes (which may be referred to using various terminology) through a single system of (morpho)phonological rules. The purpose of both phonemic and morphophonemic analysis is to produce simpler underlying descriptions for what appear on the surface to be complicated patterns. In purely phonemic analysis the data is just a set of words in a language, while for the purposes of morphophonemic analysis the words must be considered in grammatical paradigms to take account of the underlying morphemes. It is postulated that morphemes are recorded in the speakers lexicon in an invariant (morphophonemic) form, which, in a given environment, is converted by rules into a surface form. The analyst attempts  to present as completely as possible a system of underlying units (morphophonemes) and a series of rules that act on them, so as to produce surface forms consistent with the linguistic data. Isolation forms The isolation form of a morpheme is the form in which that morpheme appears in isolation (when not subject to the effects of any other morpheme). In the case of a bound morpheme, such as the English past tense ending -ed, it will generally not be possible to identify an isolation form, since such a morpheme does not occur in isolation. It is often reasonable to assume that the isolation form of a morpheme provides its underlying representation. For example, in some American English, plant is pronounced [plà ¦nt], while planting is [ˈplà ¦nÉ ªÃ…‹], where the morpheme plant- appears in the form [plà ¦n]. Here the underlying form can be assumed to be //plà ¦nt//, corresponding to the isolation form, since rules can be set up to derive the reduced form [plà ¦n] from this (while it would be difficult or impossible to set up rules that would derive the isolation form [plà ¦nt] from an underlying //plà ¦n//). This is not always the case, however; sometimes the isolation form itself is subject to neutralization that does not apply to some other instances of the morpheme. For example, the French word petit (small) is pronounced in isolation without the final [t] sound, although in certain derived forms (such as the feminine petite) the [t] is heard. If the isolation form were adopted as the underlying form, the information that there is a final t would be lost, and it would be hard to explain the appearance of the t in the inflected forms. Rule ordering Morphophonological rules are generally considered to apply in a set order. This means that the application of one rule may sometimes either prevent or enable the application of another rule provided the rules are appropriately ordered. If the ordering of two rules is such that the application of the first rule can have the effect of making it possible to apply the second, then the rules are said to be in feeding order. For example, if a language has an apocope rule (A) which deletes a final vowel, and a cluster reduction rule (CR) that reduces a final consonant cluster, then the rules are in feeding order if A precedes CR, since the application of A can enable application of CR (for example, a word ending /-rpa/ is not itself subject  to CR, since the consonant cluster is not final, but if A is applied to it first, leaving /-rp/, then CR can apply). Here rule A is said to feed rule CR. If the rules are ordered such as to avoid possible feeding (in this case, if CR applies before A) then they are said to be in counter-feeding order. On the other hand, if rules are ordered such that the application of the first rule can have the effect of preventing application of the second, then the rules are said to be in bleeding order. For example, if a language has an epenthesis rule (E) that inserts a /w/ before certain vowels, and a vowel deletion rule (D) that deletes one of two consecutive vowels, then the rules are in bleeding order if E precedes D, since the application of E can prevent application of D (for example, a word containing /-iu-/ would be subject to D, but if E is applied to it first, leaving /-iwu-/, then D can no longer apply). Here rule E is said to bleed rule D. If the rules are ordered such as to avoid possible bleeding (in this case, if D applies before E) then they are said to be in counter-bleeding order. The terminology of feeding and bleeding is also applied to other linguistic rules, such as those of historical sound changes. Morphophonology and orthography The principle behind alphabetic writing systems is that the letters (graphemes) represent phonemes. However in many orthographies based on such systems the correspondences between graphemes and phonemes are not exact, and it is sometimes the case that certain spellings better represent a words morphophonological structure rather than the purely phonological. An example of this is that the English plural morpheme is written -s regardless of whether it is pronounced as /s/ or /z/; we write cats and dogs, not dogz. The above example involves active morphology (inflection), and morphophonemic spellings are common in this context in many languages. Another type of spelling that can be described as morphophonemic is the kind that reflects the etymology of words. Such spellings are particularly common in English; examples include science /saÉ ª/ vs. unconscious /ÊÆ'/, prejudice /prÉ›/ vs. prequel /priË /, sign /saÉ ªn/ signature /sÉ ªÃ‰ ¡n/, nation /neÉ ª/ vs. nationalism /nà ¦/, and special /spÉ›/ vs. species /spiË /. Conclusions according to this chapter Morphophonology (also morphophonemics, morphonology) is a branch of linguistics which studies: 1. The phonological structure of morphemes. 2. The combinatory phonic modifications of morphemes which happen when they are combined. 3. The alternative series which serve a morphological function. Examples of a morphophonological alternatives in English include these distinctions: Plurals -es and -s, as in bus, buses, vs. bun, buns. Plural of -f is -ves, as in leaf, leaves. Different pronunciations for the past tense marker -ed. English, having lost its inflection, does not have much morphophonology. Inflected and agglutinating languages may have extremely complicated systems, e.g., consonant gradation. A morphophonemic rule has the form of a phonological rule, but is restricted to a particular morphological environment. Morphophonemic rules are sensitive to their environment, unlike phonological rules. Whenever morphological information is required to specify the environment for an allophonic rule, the rule is morphophonemic. The prefix /in-/ has the allomorphs [il] and [ir]: /in-/ + responsible irresponsible /in-/ + logical illogical Therefore, there must be a morphophonemic rule which determines the allomorphs [il] and [ir] of the prefix /in-/. The purpose of both phonemic and morphophonemic analysis is to produce simpler underlying descriptions for what appear on the surface to be complicated patterns. When morphemes are clustered or grouped in words than changes in the phonological structures of these words occur. Such changes are called morphophonemic changes. Assuming that we allow phonological rules to apply in sequence, we can cycle through them using the output of the first rule as the input to the second. For many cases in the data set, at most one phonological rule introduces a structural change. But in cog, tail, or comb we see a single derivation that involves both rules. Furthermore, such cases are not rare in English. Any word that begins with a voiceless stop and contains a vowel that precedes a voiced consonant will require the application of both rules. We use cog as an illustrative example: Allophone Central to the concept of the phoneme is the idea that it may be pronounced in many different ways. In English (BBC pronunciation) we take it for granted that the r sounds in ‘ray’ and ‘tray’ are â€Å"the same sound† (i.e. the same phoneme), but in reality the two sounds are very different – the r in ‘ray’ is voiced and non-fricative, while the r sound in ‘tray’ is voiceless and fricative. In phonemic transcription we use the same symbol r for both, but we know that the allophones of r include the voiced nonfricative sound É ¹ and the voiceless fricative one . In theory a phoneme can have an infinite number of allophones, but in practice for descriptive purposes we tend to concentrate on a small number that occur most regularly. Phoneme This is the fundamental unit of phonology, which has been defined and used in many different ways. Virtually all theories of phonology hold that spoken language can be broken down into a string of sound units (phonemes), and that each language has a small, relatively fixed set of these phonemes. Most phonemes can be put into groups; for example, in English we can identify a group of plosive phonemes p, t, k, b, d a group of voiceless fricatives f, ÃŽ ¸, s, ÊÆ', h, and so on. An important question in phoneme theory is how the analyst can establish what the phonemes of a language are. The most widely accepted view is that phonemes are contrastive and one must find cases where the difference between two words is dependent on the difference between two phonemes: for example, we can prove that the difference between ‘pin’ and ‘pan’ depends on the vowel and that i and are different phonemes. Pairs of words that differ in just one phoneme are known as minimal pairs. We can establish the same fact about p and b by citing ‘pin’ and ‘bin’. Of course, you can only start doing commutation tests like this when you have a provisional list of possible phonemes to test, so some basic phonetic analysis must precede this stage. Other fundamental concepts used in phonemic analysis of this sort are complementary distribution, free variation, distinctive feature and allophone. Different analyses of a language are possible: in the case of English some phonologists claim that there are only six vowel phonemes, others that there are twenty or more (it depends on whether you count diphthongs and long vowels as single phonemes or as combinations of two phonemes). It used to be said that learning the  pronunciation of a language depended on learning the individual phonemes of the language, but this â€Å"building-block† view of pronunciation is looked on no wadays as an unhelpful oversimplification. Phonemics When the importance of the phoneme became widely accepted, in the 1930s and 40s, many attempts were made to develop scientific ways of establishing the phonemes of a language and listing each phoneme’s allophones; this was known as phonemics. Nowadays little importance is given to this type of analysis, and it is considered a minor branch of phonology, except for the practical purpose of devising writing systems for previously unwritten languages. Conclusion: An allophone is a phonetic variant of a phoneme in a particular language. A phoneme is the smallest contrastive unit in the sound system of a language. A phone is one of many possible sounds in the languages of the world. Phonemics a branch of linguistic analysis involving the study of phonemes, the structure of a language in terms of phonemes. General conclusion Morphophonemics, in linguistics, study of the relationship between morphology and phonology. Morphophonemics involves an investigation of the phonological variations within morphemes, usually marking different grammatical functions; e.g., the vowel changes in â€Å"sleep† and â€Å"slept,† â€Å"bind† and â€Å"bound,† â€Å"vain† and â€Å"vanity,† and the consonant alternations in â€Å"knife† and â€Å"knives,† â€Å"loaf† and â€Å"loaves.† The ways in which the morphemes of a language are variously represented by phonemic shapes can be regarded as a kind of code. This code is the morphophonemic system of the language. The morphophonemics of English is never so simple. There are always many instances of two or more morphemes represented by the same phonemic shape, and there are always cases in which a single morpheme is represented now by one phonemic shape, now by another. Therefore the morphophonemics of English is never trivial. Literature: 1. Hayes, Bruce (2009). Morphophonemic Analysis Introductory Phonology, pp. 161–185. Blackwell. 2. R. Jakobson, C. G.
