Chapter 7 summarizes the key findings reported from the case studies involving contests in Georgia, Kansas, South Carolina, Montana, Pennsylvania, Arizona, Ohio, and Alabama, and quantitative analyses of almost three hundred special elections to Congress. Review of these special elections points to generalizations about the factors that lead to successes in these contests, and also how a political party might proceed if it hopes to win a seat away from the opposite party.

This article demonstrates effects on utilization of a clinical transformation: changing locus of care from a dedicated sickle cell day unit to an approach that “fast-tracks” patients through the emergency department (ED) into an observation unit with 24/7 access. Retrospective quantitative analyses of claims and Epic electronic medical record data for patients with sickle cell disease treated at Thomas Jefferson University (inpatient and ED) assessed effects of the clinical transformation. Additionally, case studies were conducted to confirm and deepen the quantitative analyses. This study was approved by the Thomas Jefferson University Institutional Review Board. The quantitative analyses show significant decreases in ED and inpatient utilization following the transformation. These effects likely were facilitated by increased observation stays. This study demonstrated the impact on utilization of transformation in care (from dedicated day unit to an approach that fast-tracks patients into an observation unit). Additional case studies support the quantitative findings.

Social acceptance has proven to be a significant barrier in the implementation of renewable energy systems (hereinafter “RES”). While a general acceptance of RES is high, low local acceptance has hindered the development of renewable energy projects (hereinafter “REP”). This study assesses the determinants of local and general social acceptance of REP across Europe through a qualitative analysis from 25 case studies of the most significant social drivers and barriers that include all European countries. These case studies contain qualitative and quantitative analyses of the main factors for social acceptance of many representative groups including residents, stakeholders, and experts. Understanding the influences of social acceptance enables us to create strategies that will promote the development of REP by mitigating any public opposition.

This paper addresses the equivalence often drawn between labels such as ESL, New Englishes and Outer Circle on the one hand, and between EFL, Learner Englishes and Expanding Circle on the other. It argues that this mapping takes insufficient account of both intra-varietal variation and inter-varietal similarities. We compare the two non-native varietal types with each other and with native English on the basis of ‘user’ data from the International Corpus of English and the Corpus of Dutch English, focusing on three-word clusters in academic writing. Quantitative analyses reveal no clear grouping per circle, but rather a regional East Africa grouping. Case studies of four specific clusters (in case of, due to the, the fact that and the other hand) mostly show a native/non-native divide. Characteristics of both ESL and EFL, including innovative processes as well as learner strategies, are shown to be at play in the Outer and Expanding Circle alike. The findings are consistent with the notion of neither a strict divide between varietal types, nor a continuum.

Special elections rarely attract the attention of scholars, in contrast with journalists, who often focus on these events as predictors of what will happen in the next regular election. Special elections have never attracted more media coverage and financial support than during 2017–2018. Chapter 1 introduces the historical context, nature, and significant impact of special elections on the U.S. Congress, where at times they have provided entry to more legislators than the defeat of incumbents in regularly scheduled elections. This chapter also provides the theoretical framework for analyzing special elections and reviews the authors’ planned case studies and quantitative analyses.

Sociologists have long been fascinated with occupations and professions, both as forms of social organization and as the locus for other social processes and dynamics. Social control and cohesion, differentiation and inequality, collective action, power and influence, and identity formation are just a few of the topics considered by sociologists studying occupations and professions. Four strands of literature compose the sociology of occupations and professions, broadly defined. One strand tackles the division of labor, with the goal of understanding how positions in the division of labor are differentiated from one another (e.g., professions from other occupations), and how those differences are maintained. A second examines occupational communities, and, in particular, the relationship between occupational membership and individual behavior. A third strand focuses on the social activity of work itself, including the labor process, employer control of work, alienation and job satisfaction, unionization and its recent discontents, and the rise and fall of skills. Another thread of scholarship considers how occupations become associated with rewards (e.g., pay, prestige, authority, etc.). The field of occupations and professions has diversified methodologically in recent years, opening up new modes of inquiry into some of these topics. Indeed, whereas case studies of particular occupations dominated the field in the latter half of the 20th century, major empirical research in the last decade have included ethnographies, comparative case studies, network analyses, and quantitative analyses of survey data. And, although the pace of theoretical innovation in the “professions” literature may have slowed in recent years, the field remains a vibrant arena for studies of globalization, technological change, corporate reorganization and changes in employment practices, and the emergence of “new” types of work (e.g., service work, emotional labor).

The book analyses two different forms of economic adversity faced by urban regions – external shocks and chronic economic distress. It then examines whether and why some regions are resilient to these different forms of adversity while others are not. The study includes quantitative analyses of the experience of all metropolitan areas from 1978-2014, including a special analysis of the Great Recession. It also includes intensive case studies of six regions. The case studies focus on the problems faced by each of the regions and the public policies adopted to deal with these problems. Two chapters are then devoted to an in depth discussion of whether the most common policies and/or practices employed were likely to have been successful. The final chapter asks what we can expect of explicit economic development policies as contributors to resilience and what are the lessons for economic development policy makers and practitioners?

This chapter explains the hypotheses regarding state violence, with respect to the choice situations faced by leaders at election time. State and state-affiliated actors, including incumbent political leaders, have the greatest degree of latitude in selecting electoral strategies, and in particular deciding whether to use violence. The hypotheses are tested empirically on the basis of global data sets of electoral violence and covariates drawn from a variety of sources, supplemented by case studies based on qualitative data. The quantitative analyses confirm the connection between the structure of power (the relative strength of democratic and informal institutions) and electoral violence, and find also a strong empirical link between state-initiated violence and electoral misconduct in contexts where democratic constraints are lacking. Case studies of Zimbabwe, Syria, Belarus, and Paraguay show how state-initiated electoral violence forms part of political economies regulated by informal institutions of corruption and patronage.

Inorganic particulate material of diverse types is present in the ambient and occupational environment, and exposure to such materials is a well recognized cause of some lung disease. To investigate the interaction of inhaled inorganic particulates with the lung it is necessary to obtain quantitative information on the particulate burden of lung tissue in a wide variety of situations. The vast majority of diagnostic and experimental tissue samples (biopsies and autopsies) are fixed with formaldehyde solutions, dehydrated with organic solvents and embedded in paraffin wax. Over the past 16 years, I have attempted to obtain maximal analytical use of such tissue with minimal preparative steps. Unique diagnostic and research data result from both qualitative and quantitative analyses of sections. Most of the data has been related to inhaled inorganic particulates in lungs, but the basic methods are applicable to any tissues. The preparations are primarily designed for SEM use, but they are stable for storage and transport to other laboratories and several other instruments (e.g., for SIMS techniques).

ABSTRACTThis paper addresses the issue of corporate sustainability. It examines why achieving sustainability is becoming an increasingly vital issue for society and organisations, defines sustainability and then outlines a set of phases through which organisations can move to achieve increasing levels of sustainability. Case studies are presented of organisations at various phases indicating the benefits, for the organisation and its stakeholders, which can be made at each phase. Finally the paper argues that there is a marked contrast between the two competing philosophies of neo-conservatism (economic rationalism) and the emerging philosophy of sustainability. Management schools have been strongly influenced by economic rationalism, which underpins the traditional orthodoxies presented in such schools. Sustainability represents an urgent challenge for management schools to rethink these traditional orthodoxies and give sustainability a central place in the curriculum.
