The properties of proteins are determined not only by the sequence of amino-acid residues in the polypeptide chains, but also by the con- figuration of the chains-the way in which the chains are coiled or folded. It is probable that denaturation, the loss of some of the specific properties of a native protein, may in many cases be the result simply of a change in configuration of the polypeptide chains, without any change whatever in the sequence of amino-acid residues. During the past few years great progress has been made in the attack on the determination of the sequence of amino-acid residues in the poly- peptide chains of proteins, through the work of SANGER and his collabora- tors (Io9, IIO) and of other investigators. There has also been significant progress in the attack on the problem of the configuration of polypeptide chains, largely through the application of the X-ray diffraction technique.

Vasculitis is a term for a group of rare diseases that have in common inflammation of blood vessels and there are many types of vasculitis, and they may vary greatly in symptoms, severity and duration. Vasculitis can range from mild to life-threatening and early detection and treatment of severe vasculitis can prevent permanent damage.

The genesis of this project was a high school classroom. As a language arts teacher for students with special needs, I noticed, as any teacher might, that many of my students struggled in the foundational area of being mentored. There was a crisis of adult supervision in some of their lives. So I began the process of introducing a few of the deep truths I had acquired during my journey. I began to share some of the life lessons I had learned from adults who cared for me, as well as, lessons learned through experience. These were, in fact, many of the insights that I taught to my own children as they were growing up. Those initial classroom presentations were very popular with the students; deep meaningful discussions ensued. In fact, it became everything that a teacher would want in a lesson; students were emotionally engaged and educationally challenged. The sessions were soon dubbed "Life Lesson Friday." As it progressed, I searched for new ways to differentiate instruction, so I began writing an original poem that coincided with each life lesson. As a result, the lessons were presented in a way that now included poetry analysis. Eventually, I was encouraged to put on paper what I had been sharing in the classroom. Though the format in this book is somewhat different, because my desire is to reach a broader audience, the content is the same. My hope is that this book will become a tool in the hands of those who desire to begin a discussion on personal growth and development. Be blessed, Mark A. Albert

This publication reflects on the discussion on using chaos theory for the study of society. It explores the interface between chaos theory and the social sciences. A broad variety of fields (including Sociology, Anthropology, Economics, Political Science, Management, Philosophy and Cognitive Sciences) is represented in the book. The leading themes are: Conceptual and Methodological Issues, Social Connectionism and the Connectionist Mind, Social Institutions and Public Policy, and Social Simulations. The book includes the following topics: the relevance of the complexity-chaos paradigm for analyzing social systems, the usefulness of nonlinear dynamics for studying the formation and sustainability of social groups, the comparison between spontaneous social orders and spontaneous biological/natural orders, the building of Artificial Societies, and the contribution of the chaos paradigm to a better understanding and formulation of public policies.

Racial Battle Fatigue is described as the physical and psychological toll taken due to constant and unceasing discrimination, microagressions, and stereotype threat. The literature notes that individuals who work in environments with chronic exposure to discrimination and microaggressions are more likely to suffer from forms of generalized anxiety manifested by both physical and emotional syptoms. This edited volume looks at RBF from the perspectives of graduate students, middle level academics, and chief diversity officers at major institutions of learning. RBF takes up William A. Smith's idea and extends it as a means of understanding how the "academy" or higher education operates. Through microagressions, stereotype threat, underfunding and defunding of initiatives/offices, expansive commitments to diversity related strategic plans with restrictive power and action, and departmental climates of exclusivity and inequity; diversity workers (faculty, staff, and administration of color along with white allies in like positions) find themselves in a badlands where identity difference is used to promote institutional values while at the same time creating unimaginable work spaces for these workers.

Parsimony analysis (cladistics) has long been one of the most widely used methods of phylogenetic inference, in the fields of systematic and evolutionary biology. Moreover it has mathematical attributes that lend itself for use with complex, genomic-scale data sets. This book demonstrates the potential that this powerful hierarchical data summarization method, also has for both structural and functional comparative genomic research.

This volume provides a comprehensive review of the family, Gentianaceae, covering phylogeny, classification, biogeography, palynology, phytochemistry, and morphology, and also presents the first classification of the entire family to be published for over 100 years, generated using modern molecular- and morphology-based phylogenetic data. The volume places the Gentianaceae in context with its relatives in the order Gentianales and subclass Asteridae; presents an updated, phylogenetic classification of tribes, subtribes, and genera; investigates the corroborative value of morphological features in phylogenetic diagnoses; and comprehensively summarizes palynology, seed morphology, and phytochemistry.

The culmination of three decades of work by Michigan Natural Features Inventory ecologists, this essential guidebook to the natural communities of Michigan introduces the diverse terrain of a unique state. Small enough to carry in a backpack, this field guide provides a system for dividing the complex natural landscape of Michigan into easily understood and describable components called natural communities. Providing a new way to explore Michigan's many environments, this book details natural communities ranging from patterned fen to volcanic bedrock glade and beyond. The descriptions are supplemented with distribution maps, vibrant photographs, and comprehensive lists of characteristic plant species. The authors suggest places to visit to further study each type of natural community and provide a comprehensive glossary of ecological terms, as well as a dichotomous key for aiding field identification. An invaluable resource, this book is meant to serve as a tool for those seeking to understand, describe, document, conserve, and restore the diversity of natural communities native to Michigan.
