Book Description
Seminar paper from the year 2008 in the subject Business economics - Business Management, Corporate Governance, grade: 1,2, European Business School - International University Schloß Reichartshausen Oestrich-Winkel, language: English, abstract: The capital asset pricing model (CAPM) was introduced by William Sharpe, John Lintner, and Jan Mossin in the 1960s on the basis of Harry Markowitz’s achievements in the field of portfolio theory. Since then, the CAPM has been one of the most widely used models for evaluating the price of portfolio assets. A major element of the CAPM is the beta factor. The beta factor measures how the expected return of a stock or a portfolio correlates with the return of the whole market. (...) Obviously, the fluctuation of a stock does affect beta factors. As the value of beta is decisive for the portfolio selection process, it is necessary to provide the CAPM with a beta that represents the best possible estimate of correlation with the market. On account of this, the calculation of beta factors is complex as betas will vary over time. In addition, sample size variation can cause change within the beta. (...) The aim of this seminar paper is to show the influence of the sample size on the beta factor. Furthermore, it shall attempt to define the determinants of an ideal sample size.

Book Description
As the aging population degree is deepened, cognitive impairment has become a globally recognized public health problem. As an intermediate state from normal cognition (NC) to Alzheimer's disease (AD), mild cognitive impairment (MCI) has a highly variable cognitive trajectory, which contains three outcomes: 1) progression to AD and other types of dementia; 2) Maintaining stability; 3) Reversal to NC. Reversal of cognitive function can be achieved by taking positive and effective measures. Current studies mostly focus on factors affecting MCI to AD. World Health Organization and Alzheimer’s Disease International have also proposed relatively mature guidelines for risk factors. However, there are still some influencing factors that have not yet formed a unified conclusion. In addition, there are fewer studies and no consensus on the influencing factors for MCI to NC. Current forms of intervention for MCI are mainly non-pharmacological interventions, and there is a lack of randomized controlled trials with larger sample sizes and longer intervention periods to confirm the effect of pharmacological and non-pharmacological interventions. The purpose of this study is to explore the factors that influence the transition from MCI to AD or NC in aging adults, and to examine how the influencing factors make the cognitive function of aging adults with MCI deteriorate, improve or even reverse to NC and how are their reversal rates. This includes effective measures proven through pharmacological and non-pharmacological intervention studies and their impact on reversal. Influence factors include but are not limited to demographic factors (age, socioeconomic status, education), lifestyle (smoking, alcohol consumption, physical activity, nutrition, social participation), mental health (depression, loneliness), diseases (hypertension, diabetes, sleep disorders), biological markers (ß-amyloid, tau protein), and pharmacological factors (cholinesterase inhibitor, Aß monoclonal antibodies, drugs to rebalance the gut flora), etc., and submission of research results based on intervention trials is encouraged.

Book Description
A researchers decision about the sample to draw in a study may have an enormous impact on the results, and it rests on numerous statistical and practical considerations that can be difficult to juggle. Computer programs help, but no single software package exists that allows researchers to determine sample size across all statistical procedures. This pocket guide shows social work students, educators, and researchers how to prevent some of the mistakes that would result from a wrong sample size decision by describing and critiquing four main approaches to determining sample size. In concise, example-rich chapters, Dattalo covers sample-size determination using power analysis, confidence intervals, computer-intensive strategies, and ethical or cost considerations, as well as techniques for advanced and emerging statistical strategies such as structural equation modeling, multilevel analysis, repeated measures MANOVA and repeated measures ANOVA. He also offers strategies for mitigating pressures to increase sample size when doing so may not be feasible. Whether as an introduction to the process for students or as a refresher for experienced researchers, this practical guide is a perfect overview of a crucial but often overlooked step in empirical social work research.

Book Description
This book offers an easy-to-read, yet comprehensive introduction to practical issues in doctor–patient relationships in a typical low- and middle-income country setting in India, examining in detail the reasons for erosion of trust and providing guidance on potential research areas in the field. It strikes a balance between empirical work and theoretical normative analysis, while adopting mixed-method research in exploring important constructs in the doctor–patient relationship, such as trust, solidarity, advocacy, patient-centeredness, privacy, and confidentiality. Since the concept of trust has direct implications for the ethical practice of medicine, the book is a valuable resource for academics and researchers in the field of medical, clinical, and applied ethics.

Book Description
Practical guidance for wildlife professionals working to improve study design, data analysis, and the application of results to habitat and population management. Winner of the Wildlife Society Publications Book Award by The Wildlife Society Despite major advances in sampling techniques and analytical methods, many animal ecologists conduct research that is primarily relevant to a specific time and place. They also tend to focus more on the statistical analyses and nuances of modeling than actual study design. Arguing that studies of animal ecology should always begin with a focus on the behaviors and characteristics of individual organisms, including how they form into distinct biological populations, Applications for Advancing Animal Ecology takes a fresh and critical look at the field. Building from its companion volume, Foundations for Advancing Animal Ecology, this practical book presents readers with the principal methods used to observe animal behavior. Teaching them to assess resource abundance categories of species-environmental relationships models, it also explores • major aspects of measuring animal habitat: what to measure and how to measure it; • common sampling and estimation methods to assess population parameters; • when to measure and how to analyze data; • problems that will confront ecologists in the coming years—and how to gather information to adequately address them; and • how the experimental approach can be used to advance the science of animal ecology. Throughout the book, the authors stress the importance of speaking a common and well-defined language. Avoiding vague and misleading terminology, they assert, will help ecologists translate science into meaningful and lasting actions in the environment. Taking the perspective of the organism of interest in developing concepts and applications, the authors always keep the potentially biased human perspective in focus. They also provide a selection of suggested research projects, cautions, and caveats. A major advancement in understanding the factors underlying wildlife–habitat relationships, Applications for Advancing Animal Ecology will be an invaluable resource to natural resource management professionals and practitioners, including state and federal agencies, non-governmental organizations, and environmental consultants.
