Neither government programs nor massive charitable efforts responded adequately to the human crisis that was Hurricane Katrina. In this study, the authors use extensive interviews with Katrina evacuees and reports from service providers to identify what helped or hindered the reestablishment of the lives of hurricane survivors who relocated to Austin, Texas. Drawing on social capital and social network theory, the authors assess the complementary, and often conflicting, roles of FEMA, other governmental agencies and a range of non-governmental organizations in addressing survivors' short- and longer-term needs. While these organizations came together to assist with immediate emergency needs, even collectively they could not deal with survivors' long-term needs for employment, affordable housing and personal records necessary to rebuild lives. Community Lost provides empirical evidence that civil society organizations cannot substitute for an efficient and benevolent state, which is necessary for society to function.

Poor Families in America's Health Care Crisis examines the implications of the fragmented and two-tiered health insurance system in the United States for the health care access of low-income families. For a large fraction of Americans their jobs do not provide health insurance or other benefits and although government programs are available for children, adults without private health care coverage have few options. Detailed ethnographic and survey data from selected low-income neighborhoods in Boston, Chicago, and San Antonio document the lapses in medical coverage that poor families experience and reveal the extent of untreated medical conditions, delayed treatment, medical indebtedness, and irregular health care that women and children suffer as a result. Extensive poverty, the increasing proportion of minority households, and the growing dependence on insecure service sector work all influence access to health care for families at the economic margin.

The aim of this book is to provide an account of the state of the art in Com putational Kinematics. We understand here under this term, that branch of kinematics research involving intensive computations not only of the numer ical type, but also of a symbolic nature. Research in kinematics over the last decade has been remarkably ori ented towards the computational aspects of kinematics problems. In fact, this work has been prompted by the need to answer fundamental question s such as the number of solutions, whether real or complex, that a given problem can admit. Problems of this kind occur frequently in the analysis and synthesis of kinematic chains, when finite displacements are considered. The associated models, that are derived from kinematic relations known as closure equations, lead to systems of nonlinear algebraic equations in the variables or parameters sought. What we mean by algebraic equations here is equations whereby the unknowns are numbers, as opposed to differen tial equations, where the unknowns are functions. The algebraic equations at hand can take on the form of multivariate polynomials or may involve trigonometric functions of unknown angles. Because of the nonlinear nature of the underlying kinematic models, purely numerical methods turn out to be too restrictive, for they involve iterative procedures whose convergence cannot, in general, be guaranteed. Additionally, when these methods converge, they do so to only isolated solu tions, and the question as to the number of solutions to expect still remains."

This book contains a selected collection of papers providing an overview of the state of the art in the study of dynamical systems. A broad range of aspects of dynamical systems is covered, focusing on discrete and continuous dynamical systems, bifurcation theory, celestial mechanics, delay difference and differential equations, Hamiltonian systems and also the classic challenges in planar vector fields. Particular attention has been posed on real-world applications of dynamical systems, showing the constant interaction of the field with other sciences. The authors have made a special effort in placing the reader at the frontiers of current knowledge in the discipline. In this way, recent advances and new trends become available. The papers are based on talks given at the International Conference Dynamical Systems: 100 years after Poincare held at the University of Oviedo, Gijon (Spain), on September 3-7, 2012. Recent advances and new trends have been discussed during the meeting, including applications to a wide range of disciplines such as Biology, Chemistry, Physics and Economics, among others. The memory of Poincare, who laid the foundations of dynamical systems, provided the backdrop for the discussion of the new challenges 100 years after his death.

1. 1 Preliminary Concepts A cam mechanism is a mechanical system consisting of three basic components: a driving element, called the cam; a driven element, termed the follower; and a fixed frame. Sometimes, an intermediate element is introduced between the cam and the follower with the purpose of improving the mechanism performance. This element is called the roller because function is to produce a pure-rolling relative motion be tween the cam and the follower. The purpose ofa cam mechanism is the transmission of power or information. In applications concerning power transmission, the main good to be transmitted is force or torque; in applications ofinformation transmission, the main good transmitted takes the form of motion signals. Most modern appli cations of cam mechanisms, to be described shortly, are of the former type. Cam mechanisms used for information transmission were traditionally found in measuring instruments. With the advent ofmodern microprocessor-based hardware, this typeof application is becoming less common. Nevertheless, cam mechanisms are still used in a wide spectrum of applications, especially in automatic machines and instruments, textile machinery, computers, printing presses, food-processing equipment, internal combustion engines, control systems, and photographic equipment (Prenzel, 1989). In the design of cam mechanisms, the engineer performs several activities, namely, task definition, synthesis, analysis, optimization, and dynamic simulation. These tasks do not always follow this order. In fact, some loops may appear in the foregoing tasks, such as those illustrated in Fig. 1. 1. 1."

In the United States, work is the key to economic success, as well as the major source of health care coverage and retirement security. While Europeans look to the State for these benefits, Americans for the most part do not. This system of employment-based benefits means that those disadvantaged in the labor market are also disadvantaged in terms of health care coverage and retirement security.

The authors of this work examine the overrepresentation of Mexican Americans in low wage or service sector jobs, which rarely come with health insurance or retirement coverage. At all ages, Mexican Americans have lower rates of health insurance and retirement coverage than do other minority groups, such as African Americans or other Hispanic groups. Although employment in jobs that do not provide benefits is one major source of this disparity, other factors-including immigration history, citizenship status, and language proficiency-further block opportunities for upward mobility within the Mexican American population.

In their analysis, the authors work to deemphasize the popular, cultural explanation for the economic disparities and focus on more practical, policy-based solutions. In each chapter, the authors identify and critique the factors that affect the economic security and health care access of individuals throughout the life course, suggesting policies for reform.

This work will be of interest to anyone working in the fields of cultural studies, public health and the sociology of work. With the focus on real world causes for the problems as well as potential solutions, policy-makers will also find this informative book an essential resource.

As neoliberal philosophies and economic models spread across the globe, faith-based non-governmental ("third-sector") organizations have proliferated. They increasingly fill the gaps born of state neglect by designing and delivering social services and development programming. This collection shines a much-needed critical light onto these organizations by exploring the varied ways that faith-based organizations attempt to mend the fissures and mitigate the effects of neoliberal capitalism and development practices on the poor and powerless. The essays-grounded in empirical case studies-cover such topics as the meaning of "faith-based" development, evaluations of faith-based versus secular approaches, the influence of faith-orientation on program formulation and delivery, and examinations of faith-based organizations' impacts on structural inequality and poverty alleviation. Bridging the Gaps demonstrates the vital importance of ethnography for understanding the particular role of faith-based agencies in Latin America, revealing both the promise and the limitations of this "new" mode of development.

Almost all families will at some time have to make difficult decisions concerning aging family members, involving institutionalization, moving from medical interventions to palliative care, and even physician-assisted death. Yet, the historical transition from traditional to post-traditional society means that these decisions are no longer determined by strict rules and norms, and the growing role of the welfare state has been accompanied by changes in the nature of family and social solidarity. Advances in medical technology and greatly expanded life spans further complicate the decision-making process. Family, Intergenerational Solidarity, and Post-Traditional Society examines a range of difficult issues that families commonly face during the family life course within these contexts. The book explores both practical and ethical questions regarding filial responsibility and the roles of the state and adult children in providing financial and instrumental support to dependent parents. The book follows the experiences and deliberations of a fictional family through a series of vignettes in which its members must make difficult decisions about the treatment of a seriously ill parent. Advanced undergraduate and graduate students in family studies, gerontology/aging, sociology, social work, health and social care, and nursing will find this essential reading.

This research anthology explores the concept of food production and supply, from farm gate to plate, bringing together contemporary thinking and research on local, national, and global issues from a stakeholder perspective. A Stakeholder Approach to Managing Food includes a number of sections to represent these challenges, opportunities, conflicts, and cohesions affecting relevant stakeholder groups within food production and supply and their reaction to, engagement with, and co-creation of the food environment. For some, local, national, and global interests may seem at odds. We are in an era of growing and pervasive multi-national corporations, and these corporations have significant influence at all levels. Rapidly growing economies such as China are a focus for the global brand, but is this a scenario of adaptation or homogenization of food? Alongside this trend toward national and global development in food, this volume presents the counter-reaction that is taking place (especially in developed countries) toward local speciality and culturally bound foods, with emphasis on the importance of the inter-connection of local communities and agri-food culture and economy. With an in-depth analysis of agricultural businesses, this book shows that the entrepreneurial spirit is alive and well in rural communities with often renewed and engaged connection with consumers and imaginative use of new media. This book will be of interest to students, researchers and policy-makers concerned with agriculture, food production and economics, cultural studies.

The political and cultural implications including possible policy changes are also considered. Written in an engaging style, each chapter opens with a vignette that puts a human face on the issues. Boxed exhibits highlight social programs and policies and physical and mental health challenges that impact Latino elders. Web alerts direct readers to sites that feature more detailed information related to the chapter's issues. Each chapter also features an introduction, examples, tables, figures, a summary, and discussion questions. The self-contained chapters can be presented in any order. Latinos in an Aging World explores: Real world problems individuals face in dealing with poverty, immigration, and health and retirement decisions The latest data on Latinos as compared to research on African- and Asian- Americans where appropriate The unique historical, demographic, social, familial, and economic situations of various Latino subgroups including those from Mexico, Puerto Rico, and Cuba How ethnicity affects one's position of wealth and power and sense of citizenship. The consequence of life-long disadvantages and stigmatization on economic, physical, and mental well-being The impact of one's neighborhood and the proximity to those from similar cultures on quality of life. The introduction motivates the book and sets the stage for the entire discussion. Chapter 1 reviews the histories of the major Hispanic subgroups along with various theories as they relate to race, ethnicity, and gender that provide a conceptual framework for understanding the later chapters. Demographic, economic, and social profiles of the various Hispanic subgroups are explored in chapter 2. Next the Latino population is explored from various perspectives including the economic and social situations of men and women and their educational, marital and family, and labor force experiences. Chapter 4 examines older immigrants and their families and identifies the resources available to them in their communities that often replicate the cultural and social support system of the old country. Major health risks that older Latinos face as a result of the disadvantages they experience throughout life are examined in chapter 5. Family situations and long-term care and living arrangements of older Hispanics are examined in chapter 6. The impact of neighborhood on quality of life in terms of safety and physical and mental wellbeing is explored in chapter 7. The burden that eldercare can place upon those who bear the responsibility of their daily care is explored in chapter 8. Chapter 9 investigates the gaps in income between minority and non-Hispanic white Americans and reviews what individuals with few resources need to know about financial management. The book concludes with the social, political, and economic implications of the growing Hispanic population and the role of NGOs and other organizations in providing services to older populations. Intended for courses on Latinos and aging, diversity, race and ethnicity, minorities and aging, adult development and aging, the psychology or sociology or politics of aging, geriatric social work, public health and aging, global aging, social or family policy, and health and society taught in the behavioral and social sciences, ethnic, or Latin American/Chicano Studies, this book also appeals to researchers and practitioners who work with Hispanic families.

This expert volume provides specialized coverage of the current state of the art in carbon gels. Carbon gels represent a promising class of materials with high added value applications and many assets, like the ability to accurately tailor their structure, porosity, and surface composition and easily dope them with numerous species. The ability to obtain them in custom shapes, such as powder, beads, monoliths, or impregnated scaffolds opens the way towards numerous applications, including catalysis, adsorption, and electrochemical energy storage, among others. Nevertheless, it remains a crucial question as to which design synthesis and manufacturing processes are viable from an economic and environmental point of view. The book represents the perspectives of renowned specialists in the field, specially invited to conduct a one-day workshop devoted to carbon gels as part of the 19th International Sol-Gel Conference, SOL-GEL 2017, held on September 3rd, 2017 in Liege, Belgium. Addressing properties and synthesis through applications and industry outlook, this book represents essential reading for advanced graduate students through practicing researchers interested in these exciting materials.

Scholars from various disciplines have studied humor since antiquity. Yet, over the centuries, these researchers have also struggled to conceptualize a viable, well-accepted notion of humor. Beyond pleasure and amusement, people use humor for a variety of social functions. On the one hand, humor can cause others to like the humorous source more, attract regard, ease conversations, promote expression and the exchange of ideas, introduce new topics of discussion, or smooth interactions. On the other hand, in aggressive forms, humor can halt verbal interactions, modify the usual rules of conversation, communicate critiques, or contribute to the creation of subversive environments. Not All Claps and Cheers: Humor in Business and Society Relationships is an original research anthology that considers different angles from which to address the use of humor by individuals, groups and business actors in their interactions within, around, and across organizations-that is, at the interfaces of business and society. Accordingly, the research anthology is organized in four sections-"Humor, Business and Society," "From Society to Business: Humor's Use and Roles in Activist Movements," "From Business to Society: Humor's Use and Roles in Marketing, Corporate Communications, and Public Relations," and "Society within Business: Humor's Use and Roles in the Workplace and in Organizations." This ground-breaking research anthology draws on material from marketing, communications, human resources and stakeholder theory to throw light on this poorly understood facet of human business behavior.

Despite advances in robot technology, in which industrial manipulators have replaced mechanisms, cam mechanisms still find important industrial applications in the textile, food processing and manufacturing industries. This book is a modern, up-to-date treatise on the important subject of cam synthesis. Cam mechanisms have been studied from different points of view, namely, kinematic synthesis, dynamic synthesis, analysis, design, optimization and manufacturing. This book is oriented to the kinematic synthesis of cam mechanisms in a unified framework, i.e. that spatial, spherical and planar cam mechanisms are integrated in the same formulation. Traditionally, the synthesis of the three types of cam mechanisms has been approached using independent formulations. With a unified formulation, both well known types of cam mechanisms, as well as novel cam mechanisms can be synthesized, as shown in the book. Moreover, since all the design parameters are considered in a unified framework, the optimization theory of cam mechanisms can be applied systematically, i.e. the criteria applied for the optimization of planar cam mechanisms, which can be found to some extent in the literature, can be complemented in order to provide general criteria for the optimization of spherical and spatial cam mechanisms. The underlying philosophy of the book has been to exploit sound mathematical and kinematical tools of analysis and synthesis that could be used only with the available current software and hardware. The approach and tools introduced in this book can assist the designer in producing a broad spectrum of mechanisms than those described in the book. This will be an invaluable reference for engineering designers.

The quest for more reliable, more environment-friendly, more fuel-efficient, and more affordable products in an extremely competitive market appear as the driving forces behind the need for an integrated approach to mechanical design, analysis, and control. In this context, aircraft is being designed currently with novel electromechanical systems for the steering of its control surfaces - ailerons, rudders, and the like - while terrestrial vehicles are nowadays designed with active suspensions, to name but a few of the plethora of mechanical systems whereby an integration of disciplines is unavoidable. This book is intended to fill the gap among kinematics, dynamics, and control, as pertaining to complex mechanical systems, with the aim to ease the task of the design and control engineers as well as to assist the researchers in related disciplines in the analysis and synthesis of novel mechanical systems.

En la era de la fotografia digital, la fotografia estenopeica (pinhole) es un anacronismo que practicamente ya nadie conoce. Hace unos anos me dedique a experimentar con esta forma de hacer fotos sin lentes. En este libro he recogido lo que yo aprendi en aquella epoca sobre la fotografia estenopeica, las tecnicas para construir unas rudimentarias, pero muy efectivas, camaras de carton y una muestras de las fotografias que hice.
