Download or read book Modeling and Interpreting Interactive Hypotheses in Regression Analysis written by Robert Franzese and published by University of Michigan Press. This book was released on 2009-09-23 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: Social scientists study complex phenomena about which they often propose intricate hypotheses tested with linear-interactive or multiplicative terms. While interaction terms are hardly new to social science research, researchers have yet to develop a common methodology for using and interpreting them. Modeling and Interpreting Interactive Hypotheses in Regression Analysis provides step-by-step guidance on how to connect substantive theories to statistical models and how to interpret and present the results. "Kam and Franzese is a must-have for all empirical social scientists interested in teasing out the complexities of their data." ---Janet M. Box-Steffensmeier, Ohio State University "Kam and Franzese have written what will become the definitive source on dealing with interaction terms and testing interactive hypotheses. It will serve as the standard reference for political scientists and will be one of those books that everyone will turn to when helping our students or doing our work. But more than that, this book is the best text I have seen for getting students to really think about the importance of careful specification and testing of their hypotheses." ---David A. M. Peterson, Texas A&M University "Kam and Franzese have given scholars and teachers of regression models something they've needed for years: a clear, concise guide to understanding multiplicative interactions. Motivated by real substantive examples and packed with valuable examples and graphs, their book belongs on the shelf of every working social scientist." ---Christopher Zorn, University of South Carolina "Kam and Franzese make it easy to model what good researchers have known for a long time: many important and interesting causal effects depend on the presence of other conditions. Their book shows how to explore interactive hypotheses in your own research and how to present your results. The book is straightforward yet technically sophisticated. There are no more excuses for misunderstanding, misrepresenting, or simply missing out on interaction effects!" ---Andrew Gould, University of Notre Dame Cindy D.

Download or read book The Oxford Handbook of Political Methodology written by Janet M. Box-Steffensmeier and published by Oxford University Press. This book was released on 2008-08-21 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Political methodology has changed dramatically over the past thirty years, and many new methods and techniques have been developed. Both the Political Methodology Society and the Qualitative/Multi-Methods Section of the American Political Science Association have engaged in ongoing research and training programs that have advanced quantitative and qualitative methodology. The Oxford Handbook of Political Methodology presents and synthesizes these developments. The Handbook provides comprehensive overviews of diverse methodological approaches, with an emphasis on three major themes. First, specific methodological tools should be at the service of improved conceptualization, comprehension of meaning, measurement, and data collection. They should increase analysts' leverage in reasoning about causal relationships and evaluating them empirically by contributing to powerful research designs. Second, the authors explore the many different ways of addressing these tasks: through case-studies and large-n designs, with both quantitative and qualitative data, and via techniques ranging from statistical modelling to process tracing. Finally, techniques can cut across traditional methodological boundaries and can be useful for many different kinds of researchers. Many of the authors thus explore how their methods can inform, and be used by, scholars engaged in diverse branches of methodology.

Download or read book Impacts of Anthropogenic Activities on Watersheds in a Changing Climate written by Luís Filipe Sanches Fernandes and published by MDPI. This book was released on 2021-04-14 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: The immediate goal of this Special Issue was the characterization of land uses and occupations (LULC) in watersheds and the assessment of impacts caused by anthropogenic activities. The goal was immediate because the ultimate purpose was to help bring disturbed watersheds to a better condition or a utopian sustainable status. The steps followed to attain this objective included publishing studies on the understanding of factors and variables that control hydrology and water quality changes in response to human activities. Following this first step, the Special Issue selected work that described adaption measures capable of improving the watershed condition (water availability and quality), namely LULC conversions (e.g., monocultures into agro-forestry systems). Concerning the LULC measures, however, efficacy was questioned unless supported by public programs that force consumers to participate in concomitant costs, because conversions may be viewed as an environmental service.

Download or read book Maximum Likelihood for Social Science written by Michael D. Ward and published by Cambridge University Press. This book was released on 2018-11-15 with total page 327 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume provides a practical introduction to the method of maximum likelihood as used in social science research. Ward and Ahlquist focus on applied computation in R and use real social science data from actual, published research. Unique among books at this level, it develops simulation-based tools for model evaluation and selection alongside statistical inference. The book covers standard models for categorical data as well as counts, duration data, and strategies for dealing with data missingness. By working through examples, math, and code, the authors build an understanding about the contexts in which maximum likelihood methods are useful and develop skills in translating mathematical statements into executable computer code. Readers will not only be taught to use likelihood-based tools and generate meaningful interpretations, but they will also acquire a solid foundation for continued study of more advanced statistical techniques.

Download or read book The European Social Model under Pressure written by Romana Careja and published by Springer. This book was released on 2019-07-11 with total page 624 pages. Available in PDF, EPUB and Kindle. Book excerpt: The European Social Model is at a crossroad. Although from the 1990s onwards, the threat of an imminent crisis shaped much of the rhetoric surrounding the future of the welfare state, disagreement within the academic community remains. What is however increasingly clear is that with the global financial crisis and the Euro crisis that followed it, the challenges the European Social Model faces have become more acute and demand action. This volume launches a multifaceted inquiry into these challenges. Each contribution, written by renowned scholars in their fields, represents an in-depth exploration of issues that cut to the core of current political, economic and social processes. They are an invitation to the seasoned scholars as well as to the beginning students of social sciences, public administration or journalism to engage with, by now, a large body of scholarship, to accompany the authors in their endeavours to seek an explanation to burning questions and start their own inquiries.

Download or read book Electoral Rules and Electoral Behaviour written by Ruth Dassonneville and published by Routledge. This book was released on 2018-12-07 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: Across representative democracies, there is a strong variation in the rules that govern the electoral process. A classic insight in political science is that these rules, e.g., the presence of a majoritarian or a proportional system have a profound effect on the way a democracy functions. We know less however, about the way voters actually respond to these electoral rules. This kind of effect presupposes that voters not only are aware of the electoral system, but also that they adapt to the incentives offered by the system. In this volume, a group of international scholars investigate whether this is indeed the case. The various chapters in this volume deal with the effect of proportionality, mixed-member systems, compulsory voting and preferential voting. The chapters are based on recent data and state-of-the-art methods. The introduction confronts the findings of the various chapters with the allegedly universal validity of vote choice models in the literature. The research presented in this volume mainly deals with elections in Europe, but the findings speak to the broader community of electoral scholars. The chapters originally published as a special issue in West European Politics.

Download or read book The Biosphere and Human Society written by Larry D. Barnett and published by Policy Press. This book was released on 2023-02-28 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: Human population growth is a serious biospheric problem yet is largely overlooked. Because of the neglect of demography, environmental policies—while well-intentioned—are unlikely to succeed. This book gives a concise review of world fertility rates and population growth, and offers a valuable summary of studies of the impact of overpopulation on the biosphere. In addition, the book explains key demographic variables to consider when formulating law and government policy relevant to childbearing, and it summarizes findings of social science research—findings that contradict popular assumptions about the impact of government interventions addressing the frequency of childbearing and immigration.
