The best protection against environmental mutagens is to identify them before they ever come into general use. But it is always possible that some substance will escape detection and affect a large number of persons without this being realized until later generations. This article considers ways in which such a genetic emergency might be promptly detected. A mutation-detecting system should be relevant in that it tests for effects that are as closely related as possible to those that are feared. It should be sensitive enough to detect a moderate increase in mutation rate, able to discover the increase promptly before more damage is done, responsive to various kinds of mutational events, and designed in such a way as to maxi mize the probability that the Gause of an increase can be found. Methods based on germinal mutation necessarily involve enormous numbers of persons and tests. On the other hand, with somatic mutations the individual cell becomes the unit of measurement rather than the in dividual person. For this reason, I think that somatic tests are preferable to germinal tests, despite the fact that it is germinal mutations which are feared.

At the 1980 Christmas meetings of the American Society of zoologists in Seattle, Washington, the Division of Comparative Physiology and Biochemistry sponsored a symposium on the locomo tion and exercise of arthropods. This book is an outgrowth of that symposium. To our knowledge, the symposium and this volume are the first attempts to deal with all of the major modes of locomotion (flight, swimming, and pedestrian travel) among the arthropods in a comprehensive fashion. The time seems propitious to focus on arthropod locomotion. In the last decade enormous strides have been made in understand ing locomotion - both arthropod and vertebrate alike. There has been an explosion of new ideas, new techniques, and new data. These deserve greater attention and discussion than is possible in specialized journals. Hopefully this book will fill this gap; moreover, it should serve as a benchmark for newcomers to see what has happened to date and perhaps act as a launching pad for re search to come. Whatever the case, a symposium volume such as this serves to highlight our current strengths and weaknesses. In the present case it reveals the relative abundance of information on flying and walking and the dearth of data available on swimming; it exposes the fact that insects and crustaceans are fairly well studied and arachnids are not.

The previous volume, The Pathogenesis of Alcoholism: Psychosocial Factors, attempted to describe the interaction of biological, psychological, and social factors that lead to the initiation and perpetuation of alcoholism. The preface to that volume presented our particular view of the bio-. psycho-social interaction as a progressive process in which earlier developments produce new pathogenetic mechanisms, which in turn lead to still other cyclical feedback activities. Although influences from each of the three phenomenologic levels are at work during each stage of the clinical course, it would appear that social factors are most significant in the early phase, psychological factors at the intermediate level, and biological ones toward the end. These differences are only relative, however, for influences of all three types surely are operative during all stages of the syndrome. This appears to be particularly true for the biological parameters of activity. Don Goodwin (1976), who has supplied much of the data that support the role of hereditary factors in alcoholism, is wont to say that all living behavior is biological-by definition. The operational evidence for this is perhaps more evident in alcoholism than in other syndromes. For example, the general social indifference of many Asians to alcohol may reflect the presence of an atypical isoenzyme of alcohol dehydrogenase rather than some independently derived cultural norm.

The rapidly expanding use of very low temperatures in research and high technology during the last several decades and the concurrent high degree of activity in cryogenic engineering have mutually supported each other, each improvement in refrigeration technique making possible wider oppor tunities for research and each new scientific discovery creating a need for a refrigerator with special features. In this book, Professor Walker has provided us with an excellent exposition of the achievements of this period, the fundamental principles involved, and a critical examination of the many different cryogenic systems which have led to a new era of low-level refrigeration. I feel fortunate to have had a part in the developments discussed in this book. During the early 1930s I constructed several rotary engines using leather vanes. Their performance was not good, but I was able to liquefy air. I had been impressed by the usefulness of leather cups in tire pumps and in Claude-type engines for air liquefaction. I was trying to find a way to avoid that part of the friction generated by a leather cup as a result of the radial force of the working gas on the cylindrical part of the cup. During the 1950s I built two efficient helium liquefiers in which essentially leather pistons were used.

Freud and Modern Psychology: The Emotional Basis of Human Behavior (Emotions, Personality, and Psychotherapy)

Freud's discovery of an emotional basis for mental illness led him to pursue the emotional basis of human behavior in general. This pursuit led him to undertake observational studies of dreams (1900), everyday mistakes (1901), sexuality (1905b), character formation (1908, 1931), jokes (1905a), and the origin of guilt (1913). Volume 2 of Freud and Modern Psychology examines the texts of each of these major writings in general psychology, continuing to explore the contradiction between Freud's observations about the power of emotions and his narrow the oretical formulations about human behavior. Volume 2 also reviews the remarkable power of the uniquely moral emotions of shame and guilt not only to create psychiatric symptoms, as discussed in Volume 1, but to infiltrate our nightly dreams, create everyday parapraxes, influence the development of sexuality, specify the emotional release in jokes, shape personality, and "create" human culture. As we saw in Volume 1, we shall see again in Volume 2 that Freud's theoretical difficulties arose from the absence of a viable theory of human nature as cultural, that is, social by biological origin. In a the oretical framework based on the cultural nature of human nature, the emotions and the social cohesion are reciprocally related to each other. The emotions are the means of the social cohesion which, in turn, is the means by which the emotions, including shame and guilt, are formed in infancy.

The Changing Definition of Masculinity is an outgrowth of four years of developing and teaching the course "Social Factors in Male Personality" at Ohio State University, Columbus. This volume reflects, in addition to my thoughts and feelings about what should be discussed in a sex-roles course taught from a male per spective, the thoughts, feelings, and knowledge of scores of students, col leagues, and friends. These are persons who either have taken the course or discussed with me appropriate material to be included in such a course and/or book. Chapter 1, for example, is influenced greatly by the work of Eliza beth and Joseph Pleck's The American Man, dealing with the periods of masculinity in the United States up to 1965. The chapter also deals with emerging meanings of masculinity after 1965, and female and male responses to these meanings. The second chapter is devoted to male sex-role socialization and examines the roles of biology and environment in male socialization. It is also concerned with agents of male socialization and with male assumption of such sex-role traits as dominance, competitiveness, the work ethic, and violence. In Chapter 2, I also propose two general mas culine roles frequently assumed by American males which mayor may not be race-specific-the White masculine role and the Black masculine role.

Eight years have elapsed since the first International Meeting on Plant Mitochondria was held in Marseilles. Since this date numerous important developments have occurred within the field and hence a further conference on this fundamental area of research was considered well overdue. This volume summarises the lecture and poster sessions of the second International Meeting on Plant Mitochondria held in Aberystwyth, July 20- 24th, 1986. The meeting was held not only to bring together plant scientists interested in the bioenergetics of plant mitochondria but also those who are interested in the regulatory role of mitochondria in plant growth and respiration. A further important aspect of this conference was to introduce plant physiologists and biochemists to the plant molecular biologists in an attempt to not only discuss problems of mutual interest but to also learn much more about the real questions which the biochemists and physiologists wish to answer. Hopefully the volume reflects much of the current excitement and advances being made in the field. Although many of the participants of the first meeting were present the expertise of Walter Bonner, Jack Hanson and Gaston Ducet, to name but a few, was sorely missed. The conference consisted of forty-five minute review lectures followed by thirty minute research lectures, the summaries of which are found in the longer articles. The meeting was divided into four seSSions, namely, organisation of the electron transport chain; mitochondrial interactions; mitochondrial biogenesis and plant growth and development.

This document is the result of a conference on "Biological Monitoring of Metals" held in Rochester, June 2-6, 1986, organized jointly by the Environmental Health Sciences Center of the School of Medicine and Dentistry of the University of Rochester, NY, and the Scientific Committee on the Toxicology of Metals within the International Commission on Occupational Health (ICOH) at the Karolinska Institute and the National (Swedish) Institute of Environmental Medicine and the University of Umea, Sweden. The aim of the Conference was to define and evaluate the scientific basis for the biological monitoring of metals. The conference was co-sponsored by the World Health Organization through its International Program on Chemical Safety and received substantial encouragement and support from the Swedish Work Environmental Fund and the United States Environmental Protection Agency. This was the second conference organized jointly by the Scientific Committee on the Toxicology of Metals and The Toxicology Division of the University of Rochester. The previous joint conference was held in 1982 on the Reproductive and Developmental Toxicity of Metals. In addition, conferences have been organized by each group (see Appendices A and B). Several of these conferences are specially relevant to the topic of the current conference. These include the joint conference mentioned above and the conferences on dose-effect and dose-response relationship held in Tokyo in 1974 and on accumulation of metals held in Buenos Aires in 1972.

Transposon tagging can work. Even though most of our understand ing about the factors that contribute to a successful tagging experiment has been accumulated from a limited number of experiments using different transposable elements in different genetic backgrounds, it is still possible to draw some conclusions regarding the best experimental strategies for gene tagging. In our experience, Spm has proved to be a good element for transposon tagging. The frequency of recovering mutable alleles in duced by Spm is not significantly different from that for Ac-Ds or for Mu 6 (summarized in Ref. 22) and varies from about 10- to 10=zr:-8pm has the unique advantage, however, in that all of the members of thiSfumily that have been examined thus far are homologous to each other at the DNA level. Therefore, by combining molecular analysis with genetic segre gation, it is possible to identify and isolate alleles that are due to insertions of either autonomous or nonautonomous Spm elements. There are definite steps one can take to increase the chances of de tecting a transposition into the gene of interest. The most important step is to select a genetic background in which the desired phenotype will be easy to screen. If the phenotype is not likely to be mutable, then tester lines should be constructed so as to contain flanking markers that can aid in subsequent segregation analyses.
