The relationship between religious belief and sexuality as personal attributes exhibits some provocative comparisons. Despite the nonestablishment of religion in the United States and the constitutional guarantee of free exercise, Christianity functions as the religious and moral standard in America. Ethical views that do not fit within this consensus often go unrecognized as moral values. Similarly, in the realm of sexual orientation, heterosexuality is seen as the yardstick by which sexual practices are measured. The notion that "alternative" sexual practices like homosexuality could possess ethical significance is often overlooked or ignored. In her new book, An "Argument for Same-Sex Marriage", political scientist Emily Gill draws an extended comparison between religious belief and sexuality, both central components of one's personal identity. Using the religion clause of the First Amendment as a foundation, Gill contends that, just as US law and policy ensure that citizens may express religious beliefs as they see fit, it should also ensure that citizens may marry as they see fit. Civil marriage, according to Gill, is a public institution, and the exclusion of some couples from a state institution is a public expression of civic inequality. An "Argument for Same-Sex Marriage" is a passionate and timely treatment of the various arguments for and against same-sex marriage and how those arguments reflect our collective sense of morality and civic equality. It will appeal to readers who have an interest in gay and lesbian studies, political theory, constitutional law, and the role of religion in the contemporary United States.

The diverse expert contributors to this volume from the fields of politics and law use moral argumentation with respect to same-sex marriage, gay rights in general, and California's Prop 8. The arguments are advanced in terms of the nation's foundational political and legal principles, extending ethical argumentation to important contemporary public policy areas such as marriage, the separation of church and state, and the rearing of children. Several chapters also contest the perceived if not actual establishment in the law and public policy of heterosexist and religious bias that continues to work against full and meaningful inclusion of sexual minorities. This bias is ironically and improperly couched in the language of American political and religious values, and it misunderstands the nation's core principles, or willfully miscasts them as inapplicable to many Americans and their families. Nonetheless, this bias is pervasive in the nation's political discourse, working to deny an important right and the recognition of equality to many citizens. The main contribution ofMoral Argument, Religion, and Same-Sex Marriage is in its direct engagement with the political and legal arguments of the gay community's critics on their own moral and ethical terms. Along the way, important concepts in public discourse such as governmental neutrality, the right to marry, and religious freedom are presented and cast in the light of liberal-democratic theory."

This volume is one of those published from the proceedings of the invited lectures to the First International Congress of Comparative Physiology and Biochemistry I organized at Liege (Belgium) in August 1984 under the auspices of the Section of Comparative Physiology and Biochemistry of the International Union of Biological Sciences. In a general foreword to these different volumes, it seems to me appropriate to consider briefly what may be the comparative approach. Living organisms, beyond the diversity of their morphological forms, have evolved a widespread range of basic solutions to cope with the different problems, both organismal and environmental with which they are faced. Soon after the turn of the century, some biologists realized that these solutions can be best comprehended in the frame work of a comparative approach integrating results of physiological and biochemical studies done at the organismic, cellular and molecular levels. The development of this approach amongst both physiologists and biochemists remained, however, extremely slow until recently."

Advances in Compararative and Environmental Physiology helps biologists, physiologists, and biochemists keep track of the extensive literature in the field. Providing comprehensive, integrated reviews and sound, critical, and provocative summaries, this series is a "must" for all active researchers in environmental and comparative physiology. Cellular volume and osmolality in animals is a well studied topic and this specific volume in the series provides the reader with a thorough grounding in this area of physiology. Consisting of two parts, the text discusses osmolality and volume control in terms of both inorganic and organic ions which as a result gives an excellent overview to those working and interested in this field.

"Physics at KAON," an international meeting jointly organized by the KFA Jillich and TRI UMF, was held in the Physikzentrum Bad Honnef from June 7 through June 9, 1989. This was one of a series of meetings - the first one in Europe - in which plans for the medium energy physics laboratory KAON were presented and some aspects of the physics at this new facility were discussed. The meeting focussed mainly on the topics of hadron spectroscopy, J{ -meson scattering, strangeness in nuclei, and rare decays. Also presented were some of the research programs at SATURNE and COSY which may well lead to KAON physics in the future. These proceed ings include articles which summarize our current experimental and theoretical knowledge in the various areas, as well as papers which describe lines of research feasible with KAON. The large number of participants - limited, in fact, by the capacity of the Physikzentrum - clearly demonstrates the great interest of the European physics community in the research avenues which will be opened by the high-intensity hadron facilities.

The aim of this symposium was to provide a framework for fruitful discussion on intestinal transport, not only for advanced scientists but also for younger people starting in this field of research. Invited lectures, communications and poster presentations were focused on four central themes, all treating the prop erties of the sole intestinal epithelium, deliberately leaving aside problems dealing with more integrative functions of the whole intestine. The importance of motility or blood circulation, for instance, is certainly capital in the overall intestinal function, but these aspects by themselves deserve another meeting. This volume has compiled the manuscripts of the invited lectures which sub stantially comprised the four sessions of the Symposium. Part 1 is designed to emphasize actual knowledge of the transport of water, inorganic as well as organic ions and molecules across the isolated intestinal epithelium. An enormous wave of investigations has emerged from studies per formed with "Ussing chambers," which roused interest in studies on absorption mechanisms and subsequently on secretory processes. This has triggered off a trend to research on isolated cells as absorption and secretion are the main func tion of the different cell types constituting the intestinal epithelium. In this first session not only the importance of the parallel arrangement of these different cellular entities is stressed, but also the role played by the paracellular route."

After the pioneering studies by Ussing and co-workers, studies of epithelial Nael transport have come a long way. The first phase of the phenomenological description of the cell as a black box has been follow ed by studies of cellular mechanisms, the interplay of the different trans port components, and the mechanisms of regulation. A broad spectrum of methods has been applied to many epithelia in a variety of species. For the individual epithelia transport schemes have been proposed, and, at this point I think it is appropriate to take a pause and search for elements common to several epithelia. This aspect triggered the publica tion of this book, and in fact the various chapters emphasize that the funetional eomponents, expressed in the various epithelia, are not in finite in number, but they occur in epithelia which are separated in evolu tion by several hundred million years. The authors come both from the field of veterinary and human physiology as weIl as from biology. In my opinion, the close contacts and eollaborations between physiologists and biologists have been essential for the progress in this field. I wish to thank all authors for their con tributions, and I hope that the reader will appreciate this collection of up to date reviews on epithelia in nonvertebrates and vertebrates."

The importance of toxins and other phanuacologically active com pounds obtained from marine animals cannot be emphasized enough. The use of these chemicals for defense or attack of other life fonus are of interest in themselves; however, they are of great importance in our understanding of their mechanisms of action in view of possible application in the defense of man (no doubt a predator) and in biol ogy and medicine. The toxin of the flat fish Pardachirus presented in some of the papers of this book is an example of a defense mechanism based on secretion of a toxin that could possibly be extended to being used to defend man himself from sharks, the marine predators par ex cellence. August, 1984 J. ZADUNAISKY Preface The study of toxins, drugs, and pollutants in the marine environment, and their impact on human life existed already in Babylon and Assyria, Egypt, Persia, India, China, Japan, Greece, Rome and South America. Nevertheless, less is known about ethnic marine biology than about ethnobotany. Only recently however, have active biotoxins been used as molecular probes in neuropharmacology, offering intriguing new insights into nervous activity and muscular functions. It is clear from the presentations at this meeting that much remains to be done, and certainly new, more pharmacologically oriented find ings lie ahead."

During the last decade, the study of behavioural endocrinology has gone through a very exciting phase. New technologies have appeared which have allowed us to answer new questions; the present book is a reflection of this progress. In the eariy1970's, the advent of steroid radioimmunoassays (RIA) for the first time permitted measurement of gonadal and adrenal steroids in small aliquots of plasma. It thus became possible to measure these hormones repeatedly in the same animals (Le., to undertake longitudinal studies) and also to assay them in small-sized animals such as the rat or the ring dove which had traditionally been favourite subjects for behavioural endocrinologists. With the RIA's, two major goals have been achieved. On one hand, it has been possible to ascertain that those hormones, whose action on behaviour had been postulated on the basis of gonadectomy and hor- mone therapy experiments, were actually present in adequate amounts in the intact animals at the time they were supposed to exert their ac- tion. On another hand, it has become feasible to measure the circulat- ing levels of steroids induced by treatments with exogenous hormones. This revealed that in a number of the early experiments the hormonal conditions which had been tested were completely outside the physi- ological range (plasma levels of steroids being several order of magni- tude above physiological levels after the injections) and a reinterpre- tation of the results was thus needed.

The idea of Professors Bolis and Gilles to gather together for a 3 days' meeting in the splendid environment of Crans-Montana in Switzerland a limited number of people around the subject of calcium and calcium bind ing proteins seemed at first particularly attractive, and when they asked me to take charge of the scientific organization of the symposium, I accepted with enthusiasm. It rapidly became clear that the major problem would be the selection of the topics, since it was impossible to cover completely and in depth such a broad and dynamic area of research. In our view, one imperative was to associate as intimately as possible the structural and the functional aspects of the areas covered. Apart from one whole day focused on the fascinating roles played by calmodulin in cellular activities, the other sessions were devoted to calmodulin-related calcium binding proteins in muscle and non muscle tissues and to some selected biological systems such as mitochondria, secretory cells or sarcoplasmic reticulum in which calcium also plays a crucial role. The presentations were made by leading investigators in their field. Some of them do not, however, appear in the present volume, for which there are two reasons: first, some of the contributions were somewhat outside the scope of the book; second, three speakers, for valid reasons, simply found no opportunity to write a manuscript in the allotted time.

Evil and barbarism continue to be associated with the totalitarian 'extremes' of twentieth-century Europe. Addressing domestic and imperial conflicts in modern Britain and beyond, as well as varied forms of representation, this volume explores the inter-relations of evil, atrocity and civilizational prejudice within liberal cultures of governance.

This volume brings together twenty original essays on the changes and continuities in gender relations and intersecting politics of sexuality, race, class and location. The book is located in debates about contemporary culture at a moment of rapid technological change, global interconnectedness and the growing cultural dominance of neoliberalism and postfeminism. The collection traverses disciplines, spaces and approaches. It is marked by an extraordinarily wide focus, ranging from analyses of celebrity magazines and makeover shows to examinations of the experiences of young female migrants, 'mail order brides' and young women who repudiate feminism. The contributions are united by their attempts to think through the ways in which experiences and representations of femininity are changing in the twenty-first century. Are we seeing new femininities? Are neoliberalism and postfeminism constructing new identities and subjectivities? What kinds of analytic tools and cultural politics are needed to critically engage with the current moment? This book will be of interest to everyone studying gender, media or cultural studies.

The second edition of this innovative book provides 'geo-relevant' chemistry in a highly accessible format. The environmental, geological and topical relevance has been enhanced, providing the ideal text to explain the relevance of chemical fundamentals to geological and environmental processes.

When I was asked to organize this symposium on marine producti vity, it made me reflect on what aspects of this subject would be stimulating to a heterogeneous group of laboratory-oriented physiolo gists and biochemists. In recent years there have been several books which discusses the methodology commonly used in primary production studies and described the magnitude of photosynthetic CO reduction 2 in various areas of the world's oceans. I therefore decided to dis pense with these conventional aspects of primary production and invite researchers to speak on a variety of problems relating the abundance and activity of phytoplankton to environmental conditions. The lectures I invited were thus quite diverse in character, but all were related either to factors affecting the rate of photosynthesis or to the fate of reduced carbon as it passes through the microbial food web. In addition to these talks the participants benefited from a number of shorter presentations and poster sessions which dealt with production and cycling of organic carbon in the marine environment.

A wealth of information on osmotic and ionic reaulation in Estuarine and Marine Animals has been accumulated over the past decades. Beyond early studies of whole-animal responses to changes in envi- ronmental salinities, efforts have been made later on to identify, to localize and to characterize the organs and structures responsible for the control of the characteristics of the cell's environmental fluid. When considering the problem of cell volume control in animals facing media of fluctuating salinities, we are indeed dealing with two different categories of mechanisms. A first one is concerned with the control of the osmolality of the intracellular fluid, hence with the processes directly implicated in the maintenance of cell volume and shape. They have been extensively described in several recent review papers. The second category includes the processes controllin~ the charac- teristics of the cell's environmental fluid in order to minimize the amplitude of the osmotic shocks the cells may have to cope with upon acclimation to media of changed salinities. They are localized in particular organs and structures : the so-called "caZt-transporting" epithelia. Up to now, most of the studies on salt-transportino epithe- lia in estuarine and marine animals used the black box approach, so that little or sometimes nothing is still known on the physiological, the biochemical and the biophysical basis of the transporting mecha- nisms as well as on the structure-function relationships.

Written in a clear and accessible style, with lots of examples from Anglo-American media, "Gender and the Media" offers a critical introduction to the study of gender in the media, and an up-to-date assessment of the key issues and debates.

Eschewing a straightforwardly positive or negative assessment the book explores the contradictory character of contemporary gender representations, where confident expressions of girl power sit alongside reports of epidemic levels of anorexia among young women, moral panics about the impact on men of idealized representations of the 'six-pack', but near silence about the pervasive re-sexualization of women's bodies, along with a growing use of irony and playfulness that render critique extremely difficult.

The book looks in depth at five areas of media - talk shows, magazines, news, advertising, and contemporary screen and paperback romances - to examine how representations of women and men are changing in the twenty-first century, partly in response to feminist, queer and anti-racist critique.

"Gender and the Media" is also concerned with the theoretical tools available for analysing representations. A range of approaches from semiotics to postcolonial theory are discussed, and Gill asks how useful notions such as objectification, backlash, and positive images are for making sense of gender in today's Western media. Finally, "Gender and the Media" also raises questions about cultural politics - namely, what forms of critique and intervention are effective at a moment when ironic quotation marks seem to protect much media content from criticism and when much media content - from Sex and the City to revenge adverts -can be labelled postfeminist.

This is a book that will be of particular interest to students and scholars in gender and media studies, as well as those in sociology and cultural studies more generally.

It is widely recognised that we are living through an 'age of the narrative'. Many of the constituent disciplines in the social sciences resonate with this trend by using life history and narrative approaches and methods. As we move on from the modernist period which prioritised objectivity into the postmodern regard for subjectivity, this resort to narrative is likely to become more apparent and explicit in academic as well as social and commercial discourse. One aspect of this narrative form which is commonly overlooked is that of the pedagogic encounter. This is the phenomenon which is addressed by all narrative and biographical research. Fundamentally reflecting and examining the narrative of our lives in the process of learning, this book provides a series of studies and guidelines for what we have termed 'narrative pedagogy.' It presents a resource for an exploration of those narrative processes that can lead to meaningful change and development for individuals and groups within a learning environment and in life-learning. This focus on life history allows us to identify and support routes to learning within the narrative landscape of learners and through these pedagogic encounters.

Chemical principles are fundamental to the Earth sciences, and geoscience students increasingly require a firm grasp of basic chemistry to succeed in their studies. The enlarged third edition of this highly regarded textbook introduces the student to such geo-relevant chemistry, presented in the same lucid and accessible style as earlier editions, but the new edition has been strengthened in its coverage of environmental geoscience and incorporates a new chapter introducing isotope geochemistry. The book comprises three broad sections. The first (Chapters 1 4) deals with the basic physical chemistry of geological processes. The second (Chapters 5 8) introduces the wave-mechanical view of the atom and explains the various types of chemical bonding that give Earth materials their diverse and distinctive properties. The final chapters (9 11) survey the geologically relevant elements and isotopes, and explain their formation and their abundances in the cosmos and the Earth. The book concludes with an extensive glossary of terms; appendices cover basic maths, explain basic solution chemistry, and list the chemical elements and the symbols, units and constants used in the book.

This book addresses the challenge of providing for the free exercise of religion without allowing religious exercise by some individuals and groups to impinge upon the conscientious convictions of others. State neutrality toward religion is impossible, because neutrality means inattention to religion for some, but leveling the playing field through accommodations or exemptions for others. Both formal and substantive neutrality have a place in addressing particular conflicts. One such example is public funding for religiously affiliated social service programs, for which neither type of neutrality is satisfactory and thus some restrictions are justifiable; conversely, private voluntary organizations that do not receive direct public funding should be allowed wide latitude regarding their practices. This title also examines the expansive free exercise claims that are now made by those who argue that following the law impinges upon their beliefs, as exemplified by the ministerial exception and the Hobby Lobby and Masterpiece Cakeshop Supreme Court cases. It concludes by analyzing the relationship between neutrality and marriage as a civil status, which impacts a variety of commitment types and plural marriage.
