The indiscriminate use of chemical substances in industrial processes and anthropogenic activities, have resulted in the release of these compounds into aquatic ecosystems through municipal, hospital and industrial discharges, producing various undesired effects on the environment and on species of ecological interest. These compounds, such as metals, pesticides, emerging pollutants and other substances are persistent and susceptible to biotic and/or abiotic transformations, yielding metabolites that can be more toxic than the original compounds. In this book, researchers from diverse environmental science disciplines share their experiences in countries such as Argentina, Brazil, Colombia and Mexico, and critically examine the problem of contaminants in aquatic ecosystems in Latin America, as well as the risks presented by their presence.

How did medieval society deal with private justice, with grudges, and with violent emotions? This ground-breaking reader collects for the first time a number of unpublished or difficult-to-find texts that address violence and emotion in the Middle Ages. The sources collected here illustrate the power and reach of the language of vengeance in medieval European society. They span the early, high, and later middle ages, and capture a range of perspectives including legal sources, learned commentaries, narratives, and documents of practice. Though social elites necessarily figure prominently in all medieval sources, sources concerning relatively low-status individuals and sources pertaining to women are included. The sources range from saints' lives that illustrate the idea of vengeance to later medieval court records concerning vengeful practices. A secondary goal of the collection is to illustrate the prominence of mechanisms for peacemaking in medieval European society. The introduction traces recent scholarly developments in the study of vengeance and discusses the significance of these concepts for medieval political and social history.
This open access book is a unique resource for health professionals who are interested in understanding the philosophical foundations of their daily practice. It provides tools for untangling the motivations and rationality behind the way medicine and healthcare is studied, evaluated and practiced. In particular, it illustrates the impact that thinking about causation, complexity and evidence has on the clinical encounter. The book shows how medicine is grounded in philosophical assumptions that could at least be challenged. By engaging with ideas that have shaped the medical profession, clinicians are empowered to actively take part in setting the premises for their own practice and knowledge development. Written in an engaging and accessible style, with contributions from experienced clinicians, this book presents a new philosophical framework that takes causal complexity, individual variation and medical uniqueness as default expectations for health and illness.
The dynamics of the workplace for nurses are examined in this volume from the perspective of four health care industries. Focusing on acute care hospitals, nursing homes, home health agencies and hospices, the contributors explore crucial issues for nursing and for health care systems. They present an extensive literature review on the causes and impacts of the US nursing shortage, introduce projections for the need for nurses and scrutinize recent policies. Results from a survey of hospitals, nursing homes, community-based employment and temporary staff agencies are discussed and integrated with interpretations of market forces.
