Welfare states face profound challenges. Widening economic and social inequalities have been intensified by austerity politics, sharpened by the rise in ethno-nationalism and exposed by the COVID-19 pandemic. At the same time, recent decades have seen a resurgence of social justice activism at both the local and the transnational level. Yet the transformative power of feminist, anti-racist and postcolonial/decolonial thinking has become relatively marginal to core social policy theory, while other critical approaches - around disability, sexuality, migration, age and the environment - have found recognition only selectively. This book provides a much needed new analysis of this complex landscape, drawing together critical approaches in social policy with intersectionality and political economy. Fiona Williams contextualizes contemporary social policies not only in the global crisis of finance capitalism but also in the interconnected global crises of care, ecology and racialized borders. These shape and are shaped at national scale by the intersecting dynamics of family, nation, work and nature. Through critical assessment of these realities, the book probes the ethical, prefigurative and transformative possibilities for a future welfare commons. This significant intervention will animate social policy thinking, teaching and research. It will be essential reading for anyone wanting to understand the complexities of social policy for the years ahead.
The discovery of novel drugs that fill unmet medical needs is important for the health and well-being of people everywhere. However, the general public knows too little about the pathways through which basic research discoveries are translated into products that protect or restore human health. In the second edition of Hallelujah Moments, Eugene H. Cordes reveals the processes and pitfalls on the route from the laboratory bench to the bedside. These are adventure stories in which wit and grit created several of the most important drugs in human medicine. This new edition adds four new tales of drug discovery: for therapy of cancer, hepatitis C, HIV/AIDS, and for weight control. The stories emphasize the integration of basic research in academe and applied research in the pharmaceutical industry and introduce the key scientists. In each case, success resulted from imagination, risk-taking, problem solving, and perseverance.

College and university faculty find themselves tasked with teaching in the face of ever-changing trends in higher education and constant shifts in the student population. Educators must balance student engagement and retention with their learning and satisfaction in a never-ending cycle of changes in technology, the economy, and the political climate. Even when certain pedagogies or classroom techniques are shown to be beneficial in one discipline, individual faculty may find it challenging to apply them in their own classrooms. This is certainly true in chemistry. Many faculty in chemistry today struggle to embrace research-based educational practices, even those coming out of our own discipline. Graduate programs in chemical education, recent reports on discipline-based education research (1), and an increase in the scholarship of teaching and learning in chemistry indicate a desire among many faculty to change-to reach students in new and exciting ways or to change curricula to better meet students' needs. Faculty are looking for things that work-techniques used by chemists, for chemists. This volume contributes to this on-going conversation. The scholarship presented within this volume is organized in three sections. The first explores innovations found to enhance the learning of typical students as well as those who may be under-prepared. Authors describe their experiences using the flipped classroom and institutional readiness models. The second section provides examples of how technology may be utilized in the chemistry classroom-from e-textbook usage to a computational chemistry program to concrete suggestions for teaching chemistry online. The final section addresses broader issues in chemistry. One chapter demonstrates how to incorporate High-Impact Educational Practices (2) into courses for chemistry majors and nonmajors. A final chapter describes how colleges can adopt the Green Chemistry Commitment. Additionally, contextual information for pedagogical change may be found in the Introduction as well as helpful tips for adopting new approaches.

This book closes a current gap by providing the scientific basis for consumer exposure assessment in the context of regulatory risk assessment. Risk is defined as the likelihood of an event occurring and the severity of its effects. The margin between the dose that leads to toxic effects and the actual dose of a chemical is identified by estimating population exposure. The objective of this book is to provide an introduction into the scientific principles of consumer exposure assessment, and to describe the methods used to estimate doses of chemicals, the statistics applied and computer tools needed. This is presented through the backgrounds of the special fields in exposure analysis, such as exposure via food and by the use of consumer products, toys, clothing and other items. As a general concept, human exposure is also understood to include exposure via the environment and from the work setting. In this context, the specific features of consumer exposure are pointed out and put into the context of regulation, in particular food safety, chemicals safety (REACh) and consumer product safety. The book is structured into three parts: The first part deals with the general concepts of consumer exposure as part of the overall risk analysis framework of risk characterization, risk assessment and risk communication. It describes the three basic features of exposure assessment (i) the exposure scenario (ii) the exposure model and (iii) the exposure parameters, addressing external and internal exposure. Also, the statistical presentation of data to characterize populations, in connection with variability, uncertainty and quality of information and the presentation of exposure evaluation results is described. The second part deals with the specific issues of exposure assessment, exposure via food consumption, exposure from use of consumer products, household products, toys, cosmetic products, textiles, pesticides and others. This part also covers methods for acquisition of data for exposure estimations, including the relevant information from regulations needed to perform an accurate exposure assessment. The third part portrays a prospect for further needs in the development and improvement of consumer exposure assessment, as well as international activities and descriptions of the work of institutions that are involved in exposure assessment on the regulatory and scientific level. And conversely, it creates the rationale for the exposure assessment details necessary to satisfy regulatory needs such as derivation of upper limits and risk management issues.
