Buch. Condizione: Neu. Neuware - My interest in X-Efficiency (XE) dates back to 1978. At the time, I was writing the dissertation for my Ph. D. at Washington State University. My dissertation was concerned with the role of attitudes in the school-to-work transition among young men. I was advised by Professor Millard Hastay (a member of my committee) to look at Leibenstein's 'new' book, Beyond Economic Man. One of the things that caught my attention was his be havioral description of (selective) rationality. It seemed that Leibenstein's behavioral description of a (selectively) rational individual was very similar to what psychologists such as Abraham Maslow were reporting as being the product of a particular motivational system. In other words, I was im pressed with the idea that what Leibenstein was referring to as X-ineffi ciency was being discussed by psychologists as 'the way it (often) is. ' So from the beginning I always considered the concept of X-(in)efficiency to be a valuable one for understanding human behavior. I have since come to believe that this is particularly true when considering behavior in non market environments, i. e. , within the firm. Work on this book, however, can most realistically said to have started with work which I began in 1982 while I was a Visiting Scholar at Harvard University. Professor Leibenstein suggested that I consider how some em pirical evidence which was being cited as evidence for the role of property rights might also be consistent with XE theory.

Buch. Condizione: Neu. Neuware - The nemerteans are a fascinating, common and often locally abundant group of invertebrates, yet for long have attracted the attention of only a handful of scientists. In recent years, however, increasing numbers of people have developed diverse research interests in the group with the result that our knowledge of these worms has rapidly advanced. Clearly there is a need for a regular series of international meetings where individuals working on these animals can meet to exchange ideas, review developments concerning nemertean biology and freely discuss future proposals. The first such meeting was held in Philadelphia during December 1983. Twenty-seven scientists from eight countries participated in the Second International Meeting on Nemertean Biology, held at the Tjarno Marine Biological Laboratory, Sweden, 11-15 August 1986. The meeting was divid ed into five sessions: two dealt with ecological studies, two with nemertean taxonomy, and the final session covered aspects of general biology. A total of 26 papers was presented; four, by N. Anadem, G. Berg, 1. Bierne, and 1.M. TurbeviIIe, were for different reasons not submitted for inclusion in this volume. Three additional presentations were made on behalf of B. Kulikova, E. N. WiIImer, and Z. Yin, all of whom were unable to participate in the meeting.

Buch. Condizione: Neu. Neuware - Antiviral chemotherapy has come of age, and, after an initial slow pro gress, the development of new antiviral agents has proceeded at a more rapid pace and the perspectives for their clinical use have increased considerably. Now, 25 years after the first antiviral assay (idoxuridine) was introduced in the clinic, it is fitting to commemorate the beginning of the antivirals' era. In its introductory chapter B.E. Juel-Jensen touches on what may be con sidered as five of the most fundamental requirements of an antiviral drug : efficacy, relative non-toxicity, easy solubility, ready availability and rea sonable cost. Surely, the antiviral drugs that have so far been used in the clinic could still be improved upon as one or more of these five essential demands are concerned. How is all began is narrated by W.H. Prusoff. The first antiviral drugs to be used in humans were methisazone and idoxuridine, the former, which is now of archival interest, in the prevention of smallpox, the latter, which was approved for clinical use in the United States in 1962, for the topical treatment of herpetic keratitis. In terms of potency, also because of solubility reasons, idoxuridine has been superseded by trifluridine in the topical treatment of herpes simplex epithelial keratitis. H.E. Kaufman did not find trifluridine or acyclovir ef fective in the treatment of deep stromal keratitis or iritis and he reckons that other antiviral drugs (i.e. bromovinyldeoxyuridine) would not be effec tive either.

Buch. Condizione: Neu. Neuware - It is rare that we feel ourselves to be participating in history. Yet, as Bertrand Russell observed, philosophy develops in response to the challenges of socio-cultural problems and situations. The present-day philosophical endeavor is prompted not by one or two, but by a conundrum of problems and controversies in which the forces carrying life are set against each other. The struggles in which contemporary mankind is fiercely engaged are not confined, as in the past, to economic, territorial, or religious rivalries, nor to the quest for power, but extend to the primary conditions of human existence. They under mine man's primogenital confidence in life and shatter the intimacy of his home on earth. Philosophical reflection today cannot fail to feel the pressure of the current situation within which it unfolds. Since this situation now involves the ultimate conditions of human existence, its demands have at last given to philosophy the impetus and direction needed for conceiving that the first and last of its concerns should be life itself.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This series of books, 'Readings from the Encyclopedia of Neuroscience.' consists of collections of subject-clustered articles taken from the Encyclopedia of Neuroscience. The Encyclopedia of Neuroscience is a reference source and compendium of more than 700 articles written by world authorities and covering all of neuroscience. We define neuroscience broadly as including all those fields that have as a primary goal the under standing of how the brain and nervous system work to mediate/control behavior, including the mental behavior of humans. Those interested in specific aspects of the neurosciences, particular subject areas or specialties, can of course browse through the alphabetically arranged articles of the En cyclopedia or use its index to find the topics they wish to read. However. for those readers-students, specialists, or others-who will find it useful to have collections of subject-clustered articles from the Encyclopedia, we issue this series of 'Readings' in paperback. Students in neuroscience, psychology, medicine, biology, the mental health professions, and other disciplines will find that these collections provide concise summaries of cutting edge research in rapidly advancing fields. The nonspecialist reader will find them useful summary statements of important neuroscience areas. Each collection was compiled, and includes an introductory essay, by an authority in that field. 148 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -I realize more and more that to some degree psychol ogists study their own lives. My first studies in the mid-1970s looked at the conflicts that emerge in dual career couples as the partners combine their various roles. Ideas for the early studies initially came from con versations with clients, friends, and people I met trav eling. Soon after the topic of dual careers came up, dis cussions of guilt and frustration followed. The partici pants in my first studies turned out to be predominantly women. Men expressed little interest in participating. A common response was, 'Talk to my wife. ' 7 8 PREFACE Ostensibly, husbands saw their partners, but not themselves, as dealing with conflicting roles. Although I presumed this to be somewhat true, I knew from ob serving my own husband that my having a career had an immeasurable impact on him. Were men denying something Were women overly sensitive Discussions with my husband, which helped me to get a better grasp on what male partners might be feeling, planted the seed for my subsequent book on men in dual-career 1 families, published in 1985. In gathering material for that book, I was struck by the contrast with men's ear lier disinterest. Husbands appeared eager to talk about their lives. Their greatest concern-what happens to the children -became the focus of my last set of studies. Why this book 'Sharing it all' symbolizes the es sence of a two-career marriage. 252 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -In engineering and economics a certain vector of inputs or decisions must often be chosen, subject to some constraints, such that the expected costs arising from the deviation between the output of a stochastic linear system and a desired stochastic target vector are minimal. In many cases the loss function u is convex and the occuring random variables have, at least approximately, a joint discrete distribution. Concrete problems of this type are stochastic linear programs with recourse, portfolio optimization problems, error minimization and optimal design problems. In solving stochastic optimization problems of this type by standard optimization software, the main difficulty is that the objective function F and its derivatives are defined by multiple integrals. Hence, one wants to omit, as much as possible, the time-consuming computation of derivatives of F. Using the special structure of the problem, the mathematical foundations and several concrete methods for the computation of feasible descent directions, in a certain part of the feasible domain, are presented first, without any derivatives of the objective function F. It can also be used to support other methods for solving discretely distributed stochastic programs, especially large scale linear programming and stochastic approximation methods. 200 pp. Englisch.
