A good theoretical framework identifies and defines the important variables in the situation that are relevant to the problem. Moderating and mediating variables may or may not be important to the problem. A good model does and mediating variables not necessarily include moderating. 3. “Academic researchers usually develop more complex and elaborate models than applied researchers.” Discuss this statement. Academic researchers prefer to more sophisticated model which able to explains the basic until advanced means of data. Also the variety of data can be explained easily in a complex model which also able to answer questions coming from society. The applied researchers were less likely to engage in a complicated matter of model, all about applied research related to...

... Theoretical Perspectives * Theories are never “set in stone”; they are always open to change as a result of new findings? * Children shape their world as it shapes them? * Cross-cultural research enables us to determine which aspects of development are universal and which are culturally influenced? * An experiment is the most definitive way to demonstrate that one event causes another? * The results of laboratory experiments may be less applicable to real life than experiments carried out in a home, school, or public setting? These are just a few of the interesting and important topics we will cover in this chapter. Here, we present an overview both of major theories of human development and of research methods used to study it. In the first part of the chapter, we explore major issues and theoretical perspectives that underlie much research in child development. In the remainder of the chapter, we look at how researchers gather and assess information so that, as you read further in this book, you will be better able to judge whether research findings and conclu- Perspective 1: Psychoanalytic Perspective 2: Learning Perspective 3: Cognitive Perspective 4: Contextual Perspective 5:...

...PART 1 THE STUDY OF HUMAN DEVELOPMENT R esearching the process of human development across cultures provides us with an opportunity to improve the human condition as well as, hopefully, to acquire the knowledge needed to optimize life satisfaction. We therefore begin with an overview of how diverse social science and life science researchers (collectively known as developmentalists) approach the monumental task of studying humans over the course of the life span. Our discussion includes the goals of the scientific community, the recognized framework for studying the life span, what aspects of development warrant extensive examination, and what scientific methods are used to conduct research with humans. Chapter 2 discusses the main developmental theories over the past 100 years, when social scientists, biologists, and chemists focused on studying discrete aspects of human development. Earlier introspective methods about subconscious experience and contemporary measurable evidence about microscopic genetic codes, neurons, and hormones all contribute to our understanding of the human condition. Contemporary researchers are focusing on how to integrate scientific findings and theory from across cultures into a more meaningful whole about human development. CHAPTER 1 Introduction Critical Thinking Questions 1. Developmental change takes place in three fundamental domains: physical, cognitive, and emotional-social. Which domain has been most important for...

Direction: whether the relationship is positive or negative • 3. Strength of Association: how strong/consistent the relationship is (strong, moderate, weak) o Relationships should be assessed in this order How to Analyze Relationships 1. Choose variables to analyze 2. Determine if the variables are interval/ratio or nominal/ordinal 3. Use the correct relationship analysis a. For two interval/ratio variables – use correlation b. For two nominal/ordinal variables – use cross-tabs 4. Does a relationship exist? 5. If relationship exists, determine the direction a. Monotonic will be increasing/decreasing b. Nonmonotonic will be looking for a pattern 6. Assess the strength of relationship a. With correlation – size of coefficient denotes the strength b. With cross-tabs – the pattern is assessed Cross-Tabulations and Chi Square • Cross-tabulations o Consists of rows and columns defined by the categories classifying each variable.

...The Effects of Working Capital Management on Firm Profitability A study examining the impacts of different company characteristics Authors: Hampus Björkman & Micael Hillergren Supervisor: Lars Lindbergh Student Umeå School of Business and Economics Spring semester 2014 Degree project, 30 HP Abstract Many argue that there is a trade off between profitability and liquidity. However, many studies have found that the profitability can increase with an efficient Working Capital Management. Correctly allocating cash flows to where and when it is needed increases liquidity and simultaneously increasing profitability. The purpose of this study is to develop the research on the relationship between Working Capital Management and profitability by investigating how it is affected by different company characteristics. A quantitative method was applied with philosophical stances in objectivism and positivism and deductive theory was used to approach the subject. From the theoretical framework, five hypotheses were established and statistically tested in order to answer our research question. The first hypothesis was formulated to confirm previous research, while the remaining two aimed at providing both a theoretical and practical contribution to existing knowledge. The thesis centers on the Cash Conversion Cycle, a metric of how fast a company turns purchased products into profit, with Gross Profit Margin as the measure of profitability. The...

...Marketing Research Managers need information in order to introduce products and services that create value in the mind of the customer. But the perception of value is a subjective one, and what customers value this year may be quite different from what they value next year. As such, the attributes that create value cannot simply be deduced from common knowledge. Rather, data must be collected and analyzed. The goal of marketing research is to provide the facts and direction that managers need to make their more important marketing decisions. To maximize the benefit of marketing research, those who use it need to understand the research process and its limitations. Marketing Research vs. Market Research These terms often are used interchangeably, but technically there is a difference. Market research deals specifically with the gathering of information about a market's size and trends. Marketing research covers a wider range of activities. While it may involve market research, marketing research is a more general systematic process that can be applied to a variety of marketing problems. The Value of Information Information can be useful, but what determines its real value to the organization? In general, the value of information is determined by: * The ability and willingness to act on the information. * The accuracy of the information. * The level of indecisiveness that would exist without the information. * The amount of variation in the possible...

...COMPREHENSIVE EXAM QUESTIONS IN RESEARCH METHODS(1) 1. PHILOSOPHY, LOGIC AND ETHICS OF SCIENCE A) General A1. A2. A3. Starbuck has suggested that "the properties shared by all organizations ought to be uninteresting TH and unimportant." He also notes that "although statements about averages bother very few, they ought to bother many" (Journal of Management Studies, vol. 30(6), 1993). Do you agree with these statements? If so, why, and what are the implications of your beliefs for research methods in strategic management and organization science? If not, why not, and what are the implications of your beliefs for research methods in those areas? Lay out the components of the Runkel and McGrath (1972) Research Cycle and the Martin (1982) Garbage Can Model of the research process. What are the aims of either approach? What assumptions does each approach make? What basic themes does each approach emphasize? What kinds of constraints on the process of doing research does each approach highlight? How are the two approaches alike and different in other ways? What are the likely pitfalls of viewing the research process from only one of these two viewpoints? Define (and discuss important features or issues concerning) the following constructs of Philosophy and Logic of Science. (Define any four terms). 1. Null hypothesis 3. Paradigm 4. Independent variable 5. Operational definition 6. Nomological network 8. The fallacy of affirming the consequent 9. Theory 2....

...Requirements for the Degree of Doctor of Education Specializing in Educational Leadership and Policy Studies February, 2010 Accepted by the Faculty of the Graduate College, The University of Vermont, in partial fulfillment of the requirements for the degree of Doctor of Education specializing in Educational Leadership and Policy Studies. Dissertation Examination Committee: Advisor Sean M. Hurley, Ph.D. ~'W 11 Uo,~~, Patricia A. Stokowski, Ph.D. Chairperson Patricia A. Stokowski, Ph.D. Associate Dean, Graduate College Date: November 30, 2009 ABSTRACT The thesis addresses the relationship of class size to student performance in a rural state. It presents findings from a longitudinal study of a cohort of students who were tested with state assessments at grade 4 in 2000, again at grade 8 in 2004 and, finally at grade 10 in 2006. Graduation rates for five large-class sized schools and five small-class sized school populations were established in 2008. All scores (n=1137) were matched across time enabling students from similar socioeconomic backgrounds from schools that were considered small (average class size, n=11) to schools that were large (average, n= 20). The paper’s focus is on the extent that students from schools that maintained large and small classes differed in selected opportunities to learn and educational outcomes. The approach to the study utilized both large scale state databases for student backgrounds and outcomes and interviews with...

Smithb,1 + Author Affiliations aInstitute for Fiscal Studies, London WC1E 7AE, United Kingdom; and bRAND Corporation, Santa Monica, CA 90407-2138 Edited by Kenneth Wachter, University of California, Berkeley, CA, and approved February 8, 2011 (received for review November 11, 2010) Next Section Abstract In this article we assess and compare long-term adult socioeconomic status impacts from having experienced psychological and physical health problems in childhood. To do so, we use unique prospective data from the British National Child Development Study, a continuing panel study of a cohort of 17,634 children born in Great Britain during a single week in March 1958. To date there have been nine waves for this birth cohort to monitor their physical, educational, and social development, during childhood (at birth and 7, 11, and 16 y) and adulthood (age 23, 33, 42, 46, and 50 y). Excellent contemporaneous information exists throughout childhood on physical and psychological health, captured by doctor and nurse-led medical examinations and detailed parental and teacher questionnaires. This information is combined with a wealth of contemporaneous information on adult health and economic experiences collected from cohort members. Information includes their economic circumstances (earnings, labor supply, and other sources...
