...Paradigm Problems 4. In a study of portfolio allocation decisions, Moore, Kurtsberg, Fox, and Bazerman had 80 business students make decisions in a computer-based, mutual-fund-investing simulation. Each student performed the simulation by him/herself. The goal was to better understand why investors spend so much time and money on actively managed mutual funds despite the majority of those funds being outperformed by passively managed index funds (at least in recent years). The researchers hypothesized that the illusion of control would lead students to overestimate their future portfolio returns from actively selecting mutual funds and that anchoring and adjustment would influence investment decisions. (Recall that illusion of control suggests that decision makers value choice even when predicting random events outcomes for which they have no valid cues.) Most participants consistently overestimated the future performance of their investments consistent with the illusion of control. The researchers hypothesized that anchoring and adjustment would influence portfolio allocation decisions. The students were more likely to change their portfolio allocation following poorer fund performance than better fund performance, a tendency which had a negative impact on portfolio returns. The researchers attributed this to students anchoring on past performance (expecting both poor and good fund performances to continue) as they made allocation decisions. The...

The advent of the innovative blending of computers within classroom instruction referred to as digital learning by some, and by others in academic world refer the discipline as blended learning posit the possession the qualities thereof, exceptionally enhance both SDL and SRL disciplines. A wide variety of DBCL discipline programs exhibit signs of incurring the utmost in achieving efficaciously successful method of instruction with both the age of majority and minority age student proficiency, in a plethora of educational institutions, where the DBCL discipline is employed. DBCL involves the integration of computer and the Internet and Intranet into the classroom, thus allowing the communication technology as a teacher/student instruction tool, along the classroom instruction tools employed in the student’s core curriculum. DBCL disciplines demonstrate signs of the improvement of teacher/student interest, student participation, student aptitude, and of the utmost import is student academic proficiency. DBCL further reveal, when, computers...

...the modern paradigm of expression or conclude that language may be used to reinforce capitalism. But Foucault’s model of the prepatriarchialist paradigm of reality suggests that the establishment is part of the paradigm of narrativity, given that sexuality is equal to consciousness. Derrida promotes the use of textual narrative to analyse and attack sexual identity. Therefore, Scuglia[1] implies that we have to choose between the prepatriarchialist paradigm of reality and subdialectic rationalism. If textual narrative holds, the works of Joyce are an example of constructivist nihilism. In a sense, the subject is contextualised into a pretextual paradigm of narrative that includes reality as a paradox. The primary theme of the works of Joyce is not, in fact, discourse, but subdiscourse. Thus, the subject is interpolated into a prepatriarchialist paradigm of reality that includes narrativity as a totality. 2. Joyce and textual narrative “Society is intrinsically unattainable,” says Bataille. McElwaine[2] states that we have to choose between the prepatriarchialist paradigm of reality and posttextual capitalism. It could be said that several discourses concerning cultural theory may be found. The main theme of Buxton’s[3] analysis of textual narrative is the role of the artist as observer. If the modern paradigm of expression holds, we have to choose between textual nihilism and the neodialectic paradigm of expression. Thus, the premise of the prepatriarchialist paradigm of reality...

...BRM 1. What is a research paradigm?positivism?interpretivism? A research paradigm is a philosophical framework that guides how scientific research should be conducted. Positivism is underpinned by the belief that reality is independent of us and the goal is the discovery of theories, based on empirical research (observation and experiment).positivism is associated with quantitative methods of analysis. INTERPRETIVISM Interpretivism is underpinned by the belief that social reality is not objective but highly subjective because it is shaped by our perceptions. interpretivism focuses on exploring the complexity of social phenomena with a view to gaining interpretive understanding. interpretivists adopt a range of methods that 'seek to describe, translate and otherwise come to terms with the meaning, not the frequency of certain more or less naturally occurring phenomena in the social world'. 2. What is the ontological assumption? ONTOLOGICAL ASSUMPTION The ontological assumption is concerned with the nature of reality: * Positivists believe social reality is objective and external to the researcher. There fore, there is only one reality. * Interpretivists believe that social reality is subjective because it is socially constructed. Therefore, each person has his or her own sense of reality and there are multiple realities. 3. What is the epistemological assumption? EPISTEMOLOGICAL ASSUMPTION The epistemological assumption is concerned with...

...positivist and interpretive paradigms and discussion on how they are both related to the proposed study 'Chinese culture on learning and the use of meta-cognitive language-learning strategies at an institute of vocational education in Hong Kong'. By Manfred Wu "I certify that this work is entirely my own and has not been accepted as part of a submission to another degree course" _________________________ Word Length: 5,964 Abstract This paper begins with a review of the positivist and interpretive paradigms. After the description of a proposed study on Chinese values on learning and use of meta-cognitive language-learning strategies (MCLLS), how the study emerges from the two paradigms is discussed. Discussions show that the aims of the study of gathering descriptive data and exploring relationships between the two variables as well as the use of survey method are more pertained to the positivist paradigm as it shares features with the paradigm including a high degree of control over responses, use of statistics both for descriptive and for determining relationships and researchers being detached by adopting the role of an objective and passive informant. Other aims of generating insights on the two selected concepts, collecting information from respondents' frame of reference, focusing on the whole institutional setting and the use of semi-structured interview are more pertained to the interpretive paradigm. It is because the design focuses...

...The objective of this paper is to describe “immigrants are often seen as either crafty competitors for jobs or pitiful, hapless victims of ruthless employers” (Kim 2009:510). The discussion will be carried out by using ‘Mama’s family’ as background which describes the fictive kinship and undocumented immigrant restaurant workers and by using Burrell and Morgan’s (1979) paradigm framework to support my analysis. The Burrell and Morgan’s (1979) paradigm framework can be used as a difference perspective or thought which to differentiate how we view immigrants as (1) crafty competitors for jobs or (2) victims of ruthless employers. This analysis will be conduct through two dimensions provided by Burrell and Morgan (1979) of the combination of the assumption of the nature of science and the assumption of the nature of society. In the combination, the assumption for the nature of science is in term of subjectivist and objectivist dimension whilst for assumption for the nature of society in terms of regulation-change dimension. Burrell and Morgan (1979) define those four...

Methodology/approach: The paper provides an illustration of how the descriptive, exploratory and explanatory type of research is entrenched with the objectives of the research and how the combination of quantitative (statistical regression and weighting/mean ranking) and qualitative (archival analysis, qualitative interviews) methods may enhance accounting research not only from results that corroborate. Findings: The three-fold objective of this study, corresponding to its three phases, illustrates that combining qualitative and quantitative methods involves considerations at each phase of the investigation. The research design shows that when the researcher work with different types of data within the same project, the way data is used varies according to the objective and type of each phase (descriptive, explanatory and/or explanatory) of the research project. Each phase may have a particular aim and may address different concerns. However, taken together, the quantitative and qualitative findings may either corroborate,...

Brand 6 2 Summary on key learning notes 9 Bibliography 12 The Philosophy of Science The discussion of marketing as a science and the different paradigms related to it were unfamiliar to me before I read these articles included in the assignment. I had earlier gotten familiar with the discussion of economic sociology and the discussion and the debate between economics as a science (especially the neo-classic economic approach) and the subject it researches, i.e. the economic markets where these economic practices take place. It is thus also logical to become familiar with the evolution of marketing practices, as this to many degrees resembles and also equates to the evolution of economic sciences and other sciences alike. The articles are assessed in the order that I read them, since it is hopefully also possible for the reader to follow a logical construct in the development and adoption of the insight that the articles provide on marketing research. Even though this does not pose a logical progression of the articles time-wise, I still...

...Rationalist vs. Behavioralist Paradigm Problems 1. During the last five years, your instructor has discussed the emerging field of behavioral finance with many colleagues. The most common reaction has been for those colleagues to smile and say, "Behavioral finance? That's an oxymoron." Oxymoron is defined as a combination of contradictory or incongruous words (e.g. cruel kindness). Explain this reaction using a) the concept of paradigm and b) attributes of the behavioral and rational paradigms. a) According to the concept of a paradigm, someone in finance would operate on a set of principles that their work is based upon. It is the method by which they analyze their data. Under this philosophy the statement is considered an oxymoron because under the colleagues point of view they view those that study finance one that does not act on behavior. They assume that anything that involves finance automatically dictates numbers and thinking ogically in steps. It is not until there is a shift in the paradigm and that they see it from a finance position do they see the possibility of a behavioral implications. b) According to the rational paradigm, one that is interested in finance is well educated, has some predisposition towards the acclimation of wealth and is focused on the market. By the definition this means that they are rational and not behavioral. 2. The Structure of Scientific Revolutions triggered diverse reactions. Most “hard” scientists shrugged...

...research philosophies/ paradigms that you would propose for this study. Justify your answer. The research paradigms are based on quantitative and qualitative research. a) Quantitative research. The main emphasis of quantitative research is on deductive reasoning which tends to move from the general to specific, which is sometimes referred to as top down approach. The data collected is usually prepared for statistical analysis. (Wikipedia.org.). This type of research is associated the following research paradigms: 1. Positivism This is a research paradigm that tries to uncover the one truth about how things are or at least what we focus on. It also explores social reality based on philosophical ideas with the emphasis of observation and reason as means of understanding human behavior. It is therefore based on human rationality, objectivity and precision. This study demonstrated the girls transition in the World, Africa and finally how transition of girls from primary to secondary school has affected the Teso community in Kenya. The UNESCO report (2009) guided the researcher to observe that the transition rate from primary to secondary school was 62%. And it was observed that the enrollment of girls and boys was 57% and 66% respectively. (Page 4) Government of Kenya (2009) report also aided the researcher to find that the enrollment for girls at secondary level decreases to below 30% from 50% of the total enrollment at primary school level.

...1. Short Description a) Definition, origin Visual perception[1] is the ability to interpret the surrounding environment by processing information that is contained in visible light. The resulting perception is also known as eyesight or vision. However, what people see is not simply a translation of retinal stimuli (i.e., the image on the retina) [2]. Aesthetic experience of visual perception can therefore be conceptualised in three levels: sensory perception (environmental stimuli), cognition, meanings and values that the viewer may associate with this typology. (Gjerde M. 2010.) The Analysis of visual perception is a method to clarify visual information in physical environment, thus parsing human’s interpreting process into legible components...

...Samantha Roberts Student Number: Word count: 1,289 There has been an ongoing paradigm debate between quantitative and qualitative research amongst social scientists for a number of years. Qualitative Research is a particularly new concept developed to obtain and analyse data however many researchers are yet to take a liking to this concept (Bryman, 1984). Qualitative research refers to studies that are conducted in natural settings and include participant observation, focus groups and in-depth interviews. (Whitley & Crawford, 2005). These techniques provide a strong insight into how participants view events and experiences to obtain a deeper meaning into the area being studied (Willig, 2001). Quantitative research focuses on the Scientific Method which is based on a series of steps that are followed systematically to acquire data such as experiments that are then analysed and presented into numerical form. This essay will examine both research paradigms while also determining the epistemological underpinnings that determines the methods used to collect and analyse data. Qualitative researchers are mainly concerned with the social world and the influence of events and experiences that has on an individual’s perspective of the world. These researchers are not concerned with answering a specific question, more so to develop a rich understanding of a certain topic mainly through the methods of in-depth interviews, participant observation and focus groups. In-depth interviews...

The attention is now toward software paradigms since programming languages are becoming more mature. Software Development Characteristics: Software is "soft"; Complexity Human intensive Software developers did not have adequate tools to estimate the exact amount of time required for the development of an application, therefore they were most of time wrong in their estimates of time, effort, and costs Still up until today we are not able to achieve high software reliability and maintainability: is buying a software product the same as buying a TV?
