What is the probability that something will occur, and how is that probability altered by a change in an independent variable? To answer these questions, Tim Futing Liao introduces a systematic way of interpreting commonly used probability models. Since much of what social scientists study is measured in noncontinuous ways and, therefore, cannot be analyzed using a classical regression model, it becomes necessary to model the likelihood that an event will occur. This book explores these models first by reviewing each probability model and then by presenting a systematic way for interpreting the results from each.

This open access book examines health trajectories and health transitions at different stages of the life course, including childhood, adulthood and later life. It provides findings that assess the role of biological and social transitions on health status over time. The essays examine a wide range of health issues, including the consequences of military service on body mass index, childhood obesity and cardiovascular health, socio-economic inequalities in preventive health care use, depression and anxiety during the child rearing period, health trajectories and transitions in people with cystic fibrosis and oral health over the life course. The book addresses theoretical, empirical and methodological issues as well as examines different national contexts, which help to identify factors of vulnerability and potential resources that support resilience available for specific groups and/or populations. Health reflects the ability of individuals to adapt to their social environment. This book analyzes health as a dynamic experience. It examines how different aspects of individual health unfold over time as a result of aging but also in relation to changing socioeconomic conditions. It also offers readers potential insights into public policies that affect the health status of a population.

An incomparably useful examination of statistical methods for comparison The nature of doing science, be it natural or social, inevitably calls for comparison. Statistical methods are at the heart of such comparison, for they not only help us gain understanding of the world around us but often define how our research is to be carried out. The need to compare between groups is best exemplified by experiments, which have clearly defined statistical methods. However, true experiments are not always possible. What complicates the matter more is a great deal of diversity in factors that are not independent of the outcome. Statistical Group Comparison brings together a broad range of statistical methods for comparison developed over recent years. The book covers a wide spectrum of topics from the simplest comparison of two means or rates to more recently developed statistics including double generalized linear models and Bayesian as well as hierarchical methods. Coverage includes: * Testing parameter equality in linear regression and other generalized linear models (GLMs), in order of increasing complexity * Likelihood ratio, Wald, and Lagrange multiplier statistics examined where applicable * Group comparisons involving latent variables in structural equation modeling * Models of comparison for categorical latent variables Examples are drawn from the social, political, economic, and biomedical sciences; many can be implemented using widely available software. Because of the range and the generality of the statistical methods covered, researchers across many disciplines-beyond the social, political, economic, and biomedical sciences-will find the book a convenient reference for many a research situation where comparisons may come naturally.

Tourism is one of the world's largest industries and one of its fastest growing economic sectors helping to generate income and employment for local people. At the same time, it has many negative outsourced effects on the environment and local culture. Achieving a more sustainable pattern of tourism development is high on the global agenda aiming to meet human needs while preserving the environment now and for the future. The Economics of Sustainable Tourism aims to critically explore how tourism economic development can move closer to a sustainable ideal from a firm economic analytic anchor. Grounded in economic theory and application it analyzes tourist’s satisfaction and impacts of tourism on the host community, investigates the productivity of the industry and identify factors which could increase economic and sustainable development such as trade relationships. It offers further insight into how destinations sustainability can be measured, economic benefits of a more sustainable destination and sets the agenda for future research. The book includes a range of theoretical and empirical perspectives and includes cutting edge research from international scholars. This significant volume provides a new perspective on the sustainable tourism debate and will be a valuable read for students, researchers, academics of Tourism and Economics.

The Southern Africa region has experienced more than its fair share of problems in recent years. Just when it seemed that the hardships wrought by the devastating cycle of droughts and floods of 2000 to 2002 were a thing of the past, other problems emerged. At one level, there have been the weak and often erratic governance mechanisms and political crises in some countries of the region, leading to severe disruptions in agricultural production to the point that supplies and markets have virtually disappeared. At another level, socio-cultural rigidities have often militated against the adoption of efficient farming practices, resulting in sub-optimal choices that lock smallholders into a low equilibrium trap. In the face of the disappearing supplies and missing markets, these have engendered hyper-inflationary trends of a magnitude unknown anywhere else in the world. But in the midst of all this apparent dreariness, cases are emerging from which immense lessons can be drawn. This book assembles a collection of research papers based on studies completed in 2008 and 2009 in Southern Africa that examine various dimensions of the institutional constraints small farmers are facing in the region and how they are going about dealing with them. The papers draw from these diverse and polar experiences and present some theoretical and practical insights that should form the basis for more in-depth, country-level, sector-specific analyses, focusing mainly on citrus, horticultures, cotton and livestock. The thematic issues of income inequality, land reform, natural resource management and value chain governance and chain choice, are covered in this book and are expected to be of interest for a wide constituency, including researchers, development practitioners, rural animators, and policy makers.

Fixed Effects Regression Methods for Longitudinal Data Using SAS, written by Paul Allison, is an invaluable resource for all researchers interested in adding fixed effects regression methods to their tool kit of statistical techniques. First introduced by economists, fixed effects methods are gaining widespread use throughout the social sciences. Designed to eliminate major biases from regression models with multiple observations (usually longitudinal) for each subject (usually a person), fixed effects methods essentially offer control for all stable characteristics of the subjects, even characteristics that are difficult or impossible to measure. This straightforward and thorough text shows you how to estimate fixed effects models with several SAS procedures that are appropriate for different kinds of outcome variables. The theoretical background of each model is explained, and the models are then illustrated with detailed examples using real data. The book contains thorough discussions of the following uses of SAS procedures: PROC GLM for estimating fixed effects linear models for quantitative outcomes, PROC LOGISTIC for estimating fixed effects logistic regression models, PROC PHREG for estimating fixed effects Cox regression models for repeated event data, PROC GENMOD for estimating fixed effects Poisson regression models for count data, and PROC CALIS for estimating fixed effects structural equation models. To gain the most benefit from this book, readers should be familiar with multiple linear regression, have practical experience using multiple regression on real data, and be comfortable interpreting the output from a regression analysis. An understanding of logistic regression and Poisson regression is a plus. Some experience with SAS is helpful, but not required. This book is part of the SAS Press program.

Logit Modeling represents a breakthrough for researchers because it offers ways for more efficient estimation of models with multiple categorical variables, particularly whenever the measurement assumptions for classical multiple regression fail to be met. Taking an applied approach, DeMaris begins by describing the logit model in the context of the general loglinear model, moving its application from two-way to multidimensional tables. He then divides the rest of the book between an examination of the varieties of logit models for contingency tables and logistic regression. Throughout his coverage of both these major areas, DeMaris emphasizes interpretation of results. The book concludes with an extension of logistic regression to dependent variables with more than two categories.

The right to vote is the cornerstone of democracy. To millions around the world who have fought for that right, it is considered a privilege. Yet the magnitude of nonvoting in America is staggering. More than 91 million Americans did not vote in 1988, putting voter turnout at barely half of the voting-age population. This situation has stirred much comment and debate across the political spectrum, raising several questions: Why is voter turnout generally so low? Why has it declined steadily over the past three decades? Does low and declining turnout significantly bias the nature of contemporary U.S. politics? And what, if anything, can be done to increase voter participation? In this book, Ruy Teixeira addresses each of these question in detail in an effort to provide policymakers and the general public with a clearer view of the problem and possible solutions. The author's interpretations and recommendations are both provocative and firmly based on currently available data. Teixeira includes an assessment of current registration reform legislation and shows why a combination of registration reform and political reform is necessary to fully reverse the nonvoting trend and move to substantially higher turnout levels. He points out that while it is unlikely U.S. voter turnout will ever approach levels in Sweden, Australia, and Belgium—which are about 90 percent—with a thorough reform program, levels of around 70 percent, such as those in Japan and Canada, may be attainable.

This book approaches macroprudential oversight from the viewpoint of three tasks. The focus concerns a tight integration of means for risk communication into analytical tools for risk identification and risk assessment. Generally, this book explores approaches for representing complex data concerning financial entities on low-dimensional displays. Data and dimension reduction methods, and their combinations, hold promise for representing multivariate data structures in easily understandable formats. Accordingly, this book creates a Self-Organizing Financial Stability Map (SOFSM), and lays out a general framework for mapping the state of financial stability. Beyond external risk communication, the aim of the visual means is to support disciplined and structured judgmental analysis based upon policymakers' experience and domain intelligence.
