Taschenbuch. Condizione: Neu. Neuware -Das Husserlbild der Gegenwart ist noch weitgehend gepragt von den erkenntnistheoretischen 'Logischen Untersuchungen', durch die Husserl in weitem MaBe als Begriinder einer neuen objektiven Logik gilt. Mitunter wird er sogar als einseitig orien tierter Rationalist und Aufklarer des 20. J ahrhunderts, als der 'Cartesius unserer Tage' 1 angesehen. Dieses Bild Husserls kann wohl jederzeit durch seine Veroffent lichungen gerechtfertigt werden. Dennoch ist es einseitig und recht vordergriindig, da dabei voll und ganz iibersehen wird, daB auch der Bereich des Emotionalen flir HusserI ein entscheiden gut wie nichts des Interessengebiet darstellt, wovon bislang so veroffentlicht worden ist. Wohl werden in seinen Schriften gclegentlich Fragen der Wertlehre, der Asthetik und Ethik angeschnitten 2, aber eine eingehende Auseinandersetzung mit derartigen Fragen liegt in keinem der veroffentlichten Werke vor. In Wirklichkeit aber war ihm die Begriindung einer echten wissenschaftlichen Ethik immer ein ernstes philosophisches An liegen. Bereits vor den 'Logischen Untersuchungen' beschaf tigte sich Husserl mit ethischen Grundproblemen 3. Welche 1 Vgl.

This item is printed on demand - it takes 3-4 days longer - Neuware -The study of quality of life refers to the material environment (social welfare) and psychosocial environment (wellbeing). It has been defined as a concept that implies the objective and subjective dimension that Cummins (1997) first studied in seven domains. The use of domains in the quality of life study allows a more precise measurement than the one that could have been reached through simple questions, since psychometric scales are used and if the addition of domains is equivalent to the totality of life satisfaction, then the group of domains is a valid measure of quality of life. In the case of young people, it has been observed that even if they live in negative physical, social and contextual conditions, they can nevertheless experience a relatively positive experience in relation to their quality of life, depending on the strategies and capabilities that they generate in relation to the context. Similarly, young people that live in favorable socioeconomic conditions and with a trouble free psychological situation may experience a relatively poor evaluation of their position in life (Patrick et al). oung people do not form a homogenous group and, in this sense, it is not possible to generalize about youth; they interact with the environment in which they live and they are a product of the history they happen to live, in this way they transit different vital scenarios in daily life that affect their quality of life. The social representations about youth that each population has, in each historical moment, are embedded in the social context in which young people live and develop, conditioning every-day life and /or creating related stereotypes. The concept of youth is a social construction built conjointly by all members of society in the historical moment in which they live. Young people interact with the environment in which they live and they are a product of the history they happen to live. Authors like Urresti (1999) define youth from a point of view that takes into account the living together of different generations in different societies, thus being impossible to compare young people of today with those of two or three decades ago; in addition, he states that it is necessary to situate the understanding of youth within the historical and social moment in which they live. Nowadays the predominant adult model is based in individualism, and even if an intergenerational dialogue is necessary, it is difficult for young people to achieve this kind of communication with adults that, in some cases, are living 'stages of youth' or that need to be 'forever young'. Young people live in uncertainty, with a limited perspective for future action, assigning their own meaning to events and facts, according to their fundamental concerns that are significantly different from those of their parents' generation. In the other side the process of globalization and the protagonist social role of the new informational and communicational technologies, produce that the possibilities to expand individual freedoms increase, but not all young people can manage with it (Lechner, 2002). What young people need in order to construct their citizenship and feel satisfied, varies according to the different societies, especially considering that most of them live a fragile situation. As Cortina (2003:7-9) states, the idea of citizenship always transcends individualism, because the citizen is somebody that exists together with others, and those others are equal to him before the city, is somebody that deliberates with others, that acts with others conjointly, that assumes the protagonist role of his own life, in this way citizen is not only that who the law protects, but that who participates in the public issues. Speaking about young people we propose to recognize them from their equal dignity because 'recognition is not only a courtesy that we owe others: it is an essential human need' (Taylor, 1993:46). This recognition is based in human dign 68 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -The growing body of information on bacteria pathogenic for humans, mammals and plants generated within the past ten years has shown the interesting conservation of newly identified genes that playa direct role in the pathogenic mechanism. In addition to these genes, there are also genes that confer host specificities and other traits important in pathogenesis on these pathogens. In this volume, we have organized the subject areas to best fit the concept on the way bacterial pathogens recognize, interact and invade the host, on the regulation of genes involved in virulence, on the genes involved in the elaboration of toxins and other pathogenic components such as iron sequestering proteins, and on the mechanisms of circumventing the host defense systems. These areas are divided into Sections. Section I covers the first step when the pathogen seeks its host, and Sections II through VI cover subsequent steps leading to pathogenesis while avoiding host defenses. We conclude this work with a chapter summarizing information on examples of virulence mechanisms that are highly conserved. 704 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Numerous investigations over the years have illustrated the importance of physical methods, especially magnetic resonance, in the elucidation of the electronic ground states of 3d transition metal ion complexes. The results of these studies coupled with investigations on model compounds are being extended in very meaningful ways to provide electronic structural information in biological systems. In systems not readily amenable to investiga tion by single crystal X-ray diffraction these methods provide structural information as well. It was felt that a NATO Advanced Study Institute that brought together experts in theoretical aspects of magnetic resonance, experts in biology and experts in both areas would be extremely profitable for all parties attending the school. The enthusiastic response of the participants indicated that our objectives were accomplished to a high degree. We hope this pUblication of the proceedings will transmit, to some degree, the stimulating discussion of the Conference. The enormity of the area selected for this Conference can be appreciated by all.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Having the privilege of editing the English language version of this book I have found the detailed thought, explanation and step-by-step instruction that this book provides most refreshing and stimulating. There are few publications indeed that provide a completely reliable companion to bedside and out-patient instruction for the medical student - and even fewer that enhance the established physician's techniques. Medical skills in the art and science of patient examination are normally learnt experimentally - time, personal instruction and constant repetition are necessary for them to be acquired. Even then it must be admitted by many that there are some techniques that are never fully understood, properly learnt or correctly concluded - and these errors are liable to a lifetime's repetition. This volume with its excellent photographs and illustrations takes the reader clearly and incontrovertibly step-by-step through every detail of all the procedures necessary for the standard forms of examination of a patient. It is a companion for every student and doctor who wishes to learn fully and completely these necessary skills and to improve the ones they already have. Dr Alexander D. G. Gunn, Director, University Health Service, Reading, Berks, UK 1982 Preface to the Dutch edition The idea of writing this book coincided almost them a superficial acquaintance with five or six exactly with the establishment of a 'skills 'fashions' and proficiency in none of them. 300 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -The beneficial impact of the European communities involvement in scientific research and technology is wide-ranging and pervasive. There are high hopes of major advances in scientific knowledge and technological processes, while the emergence of a genuine tradition of collaborative research holds out great and continuing promise for the future. Close, frequent and long-term cooperation between universities, research centres and industry is already generating new synergies, forging a truly European scientific community. Many of tomorrows industrial developments, destined to be determinant for our economic success and prosperity, will spring from this research. The Concerted European Action on Magnets - CEAM - project is a prime example of collaborative research and development. Financed from the Communities STIMULATION action and implemented with the help of EURAM, the advanced materials programme, CEAM will bestow great benefits on European industrial competitiveness, providing a channel for high quality basic research to find its way into commercial products. This remarkable cooperative enterprise brought t~gether 58 laboratories and more than 120 scientists and englneers in a sustained thirty month effort. It spanned every aspect of new iron-based high performance magnets from theoretical modelling of their intrinsic magnetic properties to the design and construction of novel electrical devices and machines. Besides adding a new European dimension to advanced magnetic technology, CEAM also ensured that a whole new generation of young researchers and technicians have been trained in applied magnetism. 948 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -For this summer school in Athens, Greece, August 22-21, 1978, I took as my objective the presentation of a timely representative account of the application of infrared and Raman spectro scopy to biological molecules. A summer school is made up of a number of things -ideas, people, organization international collaboration and sponsorship. The exchange of ideas the student-lecturer interaction in the discussion periods and the tutorials satisfy the urgent need of all the participants to meet and discuss topics of current scientific interest. It seems therefore appropriate to publish this summer school proceedings in order to make it a lasting event and that appreciation be shown to those people and institutions that made it all possible. The summer school was held under the auspices of the Greek Ministry of Culture and Sciences under the sponsorship of the NATO Scientific Affairs Division in Brussels. In addition, support was provided by the National Hellenic Research Foundation and the Ministry of Culture and Sciences for several social and scientific functions. 384 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book gives a comprehensive overview of activities currently under way to produce, collect and compile radiation data as needed for the various types of solar energy applications in Europe. Contributions have been made by all contractors of the Commission of the European Communities, in par ticular the Meteorological Offices of the EC member countries. They all re ported on their work at a meeting which was held in October 1982 in Brussels and of which these are the proceedings. The Commission' work in this area follows a detailed strategy which was published earlier as part of the proceedings of Volume I, Series F. Series F is especially devoted to publications on the European Communities' work on solar radiation data. Other volumes within Series F are in preparation and will deal with: - solar radiation data on tilted planes; - solar radiation data derived from meteorological satellite obs- tions. In addition, two new atlases are being prepared, one showing - for the area of the European Community - maps for solar radiation on titled planes of various inclinations and orientations, and the other showing - for the whole of Europe and the Eastern part of the Mediterranean - radiation data for horizontal planes. In the latter there will also be a statistical analy sis section. Both atlases will be published in the course of 1983. 320 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Both 'land-use regulation' and 'territorial collective services' have traditionally been accomplished in cities through coercive efforts of public administrations. Recently, land-use regulation and collective service provision regimes have emerged within 'contractual communities:' territory-based organisations (usually, but not exclusively residential) such as homeowners' associations. This book examines the problems and opportunities of contractual communities, avoiding both the alarmism and unwarranted apologies found in much of the literature on contractual communities.The central notion is that cases in which coercive action by a public agency was deemed indispensable have been unjustly overstated, while the potential benefits of voluntary self-organising processes have been seriously understated. The authors propose a revised notion of the state role that allows ample leeway for contractual communities of all forms. 108 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -The field of nuclear magnetic resonance has experienced a number of spectacular developments during the last decade. Fourier transform methodology revolutionized signal acquisition capabilities. Superconducting magnets enhanced sensitivity and produced considerable improvement in spectral dispersion. In areas of new applicat ions, the life sciences particularly bene fited from these developments and probably saw the largest increase in usage. NMR imaging promises to offer a noninvasive alternative to X rays. High resolution is now achievable with solids, through magic angle spinning and cross polarization, so that the powers of NMR are applicable to previously intractable materials such as polymers, coal, and other geochemicals. The ease of obtaining relaxation times brought an important fourth variable, after the chemical shift, the coupling constant, and the rate constant, to the examination of structural and kinetic problems i~ all fields. Software development, particularly in the area of pulse sequences, created a host of useful tech niques, including difference decoupling and difference nuclear Overhauser effect spectra, multidimensional displays, signal enhancement (INEPT), coupling constant analysis for connectivity (INADEQUATE), and observation of specific structural classes such as only quaternary carbons. Finally, hardware development gave us access to the entire Periodic Table, to the particular advan tage of the inorganic and organometallic chemist. At the NATO Advanced Study Institute at Stirling, Scotland, the participants endeavored to examine all these advances, except imaging, from a multidisciplinary point of view. 568 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -A 'science of cities and regions' is critical for meeting future challenges. The world is urbanising: huge cities are being created and are continuing to grow rapidly. There are many planning and development issues arising in different manifestations in countries across the globe. These developments can, in principle, be simulated through mathematical computer models which provide tools for forecasting and testing future scenarios and plans. These models can represent the functioning of cities and regions, predicting the spatial demography and the economy, the main flows such as journey to work or to services, and the mechanisms of future evolution. In this book, the main principles involved in the design of this range of models are articulated, providing an account of the current state of the art as well as future research challenges.Alan Wilson has over forty years working with urban and regional models and has contributed important discoveries. He has distilled this experience into what serves as both an introduction and a review of the research frontier. Topics covered include the Lowry model, the retail model, principles of account-based models and the methods rooted in Boltzmann-style statistical modelling and the Lotka-Volterra approach to system evolution. Applications range from urban and regional planning to wars and epidemics. 116 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -This is the first volume of a series of books that will describe current advances and past accompli shments of mathemat i ca 1 aspects of nonlinear sCience taken in the broadest contexts. This subject has been studied for hundreds of years, yet it is the topic in whi ch a number of outstandi ng di scoveri es have been made in the past two decades. Clearly, this trend will continue. In fact, we believe some of the great scientific problems in this area will be clarified and perhaps resolved. One of the reasons for this development is the emerging new mathematical ideas of nonlinear science. It is clear that by looking at the mathematical structures themselves that underlie experiment and observation that new vistas of conceptual thinking lie at the foundation of the unexplored area in this field. To speak of specific examples, one notes that the whole area of bifurcation was rarely talked about in the early parts of this century, even though it was discussed mathematically by Poi ncare at the end of the ni neteenth century. I n another di rect ion, turbulence has been a key observation in fluid dynamics, yet it was only recently, in the past decade, that simple computer studies brought to light simple dynamical models in which chaotic dynamics, hopefully closely related to turbulence, can be observed. 436 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Since the discovery of high temperature superconductivity, a tidal wave of res earch into the newly found phenomena took off in several directions. The theor ists began to examine BSC and its implications. Mostly everyone was syn thesizing materials.The experimentalists were studying relations among electri cal and magnetic properties while the pure materials scientists began to exam ine the microstructures, and the relations of processing to one or two measurab le parameters. The engineering and systems community were preparing real conductors and designing the needed components. Each of the communities was holding between two and three annual meetings to discuss most recent re sults. As work progressed, and promised applications did not materialize, it became apparent to us that the physics and materials science communities needed to establish solid communication lines. This NATO Advanced Study Institute was thus conceived and organized. This was a two week summer school, which 15 internationally acclaimed physicists and material scientists were invited to par ticipate in the capacity of Lecturers. Eighty students, from 12 different countries, also attended. 768 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -The reinforcement of materials such as mud and clay by hair, straw and vegetable fibres has been long established in man's history, enabling him to improve his buildings and extend his engineering abilities. With the advent of modern synthetic polymers it was rapidly realised that the addition of fibres, flakes and particulate materials to polymer matrices could improve mechanical properties significantly. Fibres and flakes are the most effective and have enabled several polymers with limited properties to compete with long-established metallic materials, reSUlting in cost, weight and processing economies. This is increasingly apparent in the selection of materials for aerospace and road vehicle applications as well as in a multitude of domestic products. Reinforced plastics, both thermosets and thermoplastics, are used in increasingly harsh environments involving elevated temperatures and aggressive conditions. Fibre reinforcement of thermoplastics dominates, and a pattern of increasing replacement of fibre reinforced thermosets by reinforced thermoplastics is emerging. This trend is encouraged by the development of continuous fibre reinforced grades of the newer high-temperature engineering thermoplastics such as polyether ether ketone. The first part of this book reviews the mechanical properties and theories of short fibre reinforcement. The principal reinforcements are reviewed and a separate chapter is devoted to the uses of natural fibres as reinforcements for thermoplastics. This is an interesting and commercially important area, especially for Third World countries v vi Preface where these fibres are grown but are facing severe competition from synthetic fibres in traditional applications such as ropes and matting. 340 pp. Englisch.

In December of 1992, theorists, observers, and instrument builders gathered at the California Institute of Technology to discuss the search for answers to these questions. The International Conference, entitled `Planetary Systems: Formation, Evolution, and Detection' and supported through NASA's newly formed TOPS (Toward Other Planetary Systems) program, was the first of a series of conferences uniting researchers across disciplines and political boundaries to share thoughts and information on planetary systems. The conference was sponsored by NASA, hosted by JPL at Caltech, and endorsed by the 1992 International Space Year Association. These proceedings include discussions of topics ranging from stellar, disk, and planetary formation to new ways of searching for other stellar systems containing planets. The authors represent a wide range of nationalities, disciplines, and points of view. The second international conference took place in December of 1993. 504 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -Zeolites have been the focus of intensive activity and growth in applications over the past 25 years in ion exchange, in adsorp tion and in catalytic process technology. Beginning with the syn thetic zeolites A,X and Y, continuing into the emerging ZSM series, and including selected natural zeolites, applications span the range from large-scale purification and separation to such major petroleum and petrochemical processes as catalytic cracking and aromatics alkylation. The future promises several new areas of signiciant use as our energy resource base is expanded. As a result, a NATO Advanced Study Institute on Zeolites was held in Alcabideche, Portugal, May 1-12, 1983. Its purpose was to summarize the state-of-the-art in zeolite science and technology, with particular emphasis on recent developments. This summary is intended to complement presentations of the latest research results at the 1983 International Zeolites Association meeting in .Reno, Nevada - USA. Both the fundamentals concepts and industrial applications are addressed in the lectures of the Institute. Individual chapters cover historical development, structure, crystallography and synthesis techniques. Basic principles of adsorption, diffusion, ion exchange and acidity are reviewed. A section on catalysis addresses shape selectivity, transition metals, bifunctional catalysis and 'methanol to-gasoline'. Included in the section on industrial applications are chapters on reactor and adsorber design, catalytic cracking, xylene and n -paraffins isomerization, as well as ion exchange and adsorption. 716 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -Modern observations, including recent ones with the Hubble Space Telescope, have revealed that the Universe is replete with plasma outflows from all kinds of objects, ranging from stars in all their variety to galaxies. In this masterly survey of plasma astrophysics, written by leading practitioners, the first 15 articles in Part I deal with the use of the MHD approach in several key problems of solar plasma, such as magnetoconvection and magnetic field generation, sunspots and coronal loops, magnetic nonequilibrium and coronal heating, coronal mass ejections, the acceleration of the solar wind, and stellar winds across the Main Sequence. The following 16 articles of Part II deal with the use of the same MHD approach in several central and puzzling aspects of more distant astrophysical plasmas, such as the dynamics of the interstellar medium, collimated outflows from young stellar objects and accretion disks, molecular outflows and jets associated with enigmatic binaries and symbiotic stars, relativistic flows associated with superluminal microquasars in our own galaxy, astrophysical jets from nearby galaxies, or remote active galactic nuclei and quasars, probably fuelled by supermassive black holes. The emphasis throughout is on the striking underlying similarities in the physics of all these problems. Audience: Indispensable for solar physicists and astrophysics alike. An ideal textbook for graduate students in physics and astrophysics. 788 pp. Englisch.

However, the spectacular progress made in this area since World War II has given rise to a theoretical underpinning. The present book covers the current status of the research area and places it in perspective with the general concepts of the fields of physical chemistry involved. The ASI lectures/authors -- well known leaders in their fields -- have written presentations at the graduate level, accessible to all those who have a good general background in the thermodynamics and mass transfer theory of phase equilibria. The book will be useful to young scientists and engineers who wish to access the current frontiers in chromatography and other separation sciences. 664 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -The initial impetus for this volume was the occasion of the World Congress for Mental Health held in Vancouver, British Columbia in 1977. The theme of that congress was priorities in mental health. The keynote speaker Mrs. Rosalynn Carter, wife of the then President of the United States, focused attention on the necessity for an international perspective in understanding priorities for mental health. Without exception subsequent speakers echoed the sentiments Mrs. Carter expressed, that the first priority for mental health was that of children. For many participants the concern for children was translated not only into techniques for treatment but more importantly into broadening the approaches to prevention. One theme emerged which has begun to be addressed around the world - that of the cultural and developmental implications of sex role stereotyping for mental health. This topic proved to be the touchstone for many issues related both directly and indirectly to mental health. Among the most prominent concerns expressed were those for the effects on careers, the learning environment and relations between the sexes which stem from stereotyped attitudes concerning appropriate sex role behavior. The consensus of the par tiCipants was to urge the directorate of the congress to continue this topic at the next World Congress. This was a particularly appropriate content for the next World Congress, since 1979 was the International Year of the Child. 224 pp. Englisch.
