Taschenbuch. Condizione: Neu. Neuware -This book contains contributions from various authors on different important topics related with probabilistic methods used for the design of structures. Initially several of the papers were prepared for advanced courses on structural reliability or on probabilistic methods for structural design. These courses have been held in different countries and have been given by different groups of lecturers. They were aimed at engineers and researchers who already had some exposure to structural reliability methods and thus they presented overviews of the work in the various topics. The book includes a selection of those contributions, which can be of support for future courses or for engineers and researchers that want to have an update on specific topics. It is considered a complement to the existing textbooks on structural reliability, which normally ensure the coverage of the basic topics but then are not extensive enough to cover some more specialised aspects. In addition to the contributions drawn from those lectures there are several papers that have been prepared specifically for this book, aiming at complementing the others in providing an overall account of the recent advances in the field. It is with sadness that in the meanwhile we have seen the disappearance of two of the contributors to the book and, in fact two of the early contributors to this field. 420 pp. Englisch.

These interconnections have critical implications for conducting research that can produce valid conclusions about the causes and consequences of abuse, maltreatment, and trauma. The accumulated data on co-occurrence also provide strong evidence that prevention and intervention should be organized around the full context of individuals' experiences, not narrowly defined subtypes of violence. Managing the flood of new research and practice innovations is a challenge, however. New means of communication and integration are needed to meet this challenge, and the Web of Violence is intended to contribute to this process by serving as a concise overview of the conceptual and empirical work that form a basis for understanding the interconnections across forms of violence throughout the lifespan. It also offers ideas and directions for prevention, intervention, and public policy.A number of initiatives are emerging to integrate the findings on co-occurrence into research and action. The American Psychological Association established a new journal, Psychology of Violence, which is a forum for research on all types of violence. Sherry Hamby is the founding editor and John Grych is associate editor and co-editor of a special issue on the co-occurrence of violence in 2012. Dr. Hamby also is a co-investigator of the National Survey of Children's Exposure to Violence (NatSCEV), which has drawn attention to polyvictimization. Polyvictimization is a focus of the U.S. Department of Justice's Defending Childhood Initiative and has recently been featured in calls for grant proposals by the Office of Victims of Crime and National Institutes for Justice. 120 pp. Englisch.

These compounds are extensively used in organic syntheses and the study of their structure and spectroscopy has become fundamental.This book evaluates the best theoretical level and basis set to reproduce the experimental data existing for those compounds. To this end, the optimized geometries and wavenumbers for the normal modes of vibration are calculated and the obtained results are compared and analyzed. Also, the nature of the different types of bonds and their corresponding topological properties of electronic charge density are systematically and quantitatively investigated by using the NBO analysis and the atoms in molecules theory (AIM). 96 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -Identifying 'networked flow' as the key driver of networked creativity, this new volume in the Springer Briefs series deploys concepts from a range of sub-disciplines in psychology to suggest ways of optimizing the innovative potential of creative networks. In their analysis of how to support these networks, the contributing authors apply expertise in experimental, social, cultural and educational psychology. They show how developing a creative network requires the establishment of an optimal group experience in which individual intentions inform and guide collective goals. The volume represents a three-fold achievement. It develops a ground-breaking new perspective on group creativity: the notion of 'networked flow' as a bridging concept linking the neuropsychological, psychological and social levels of the creative process. In addition, the authors set out a six-stage model that provides researchers with a methodological framework (also by referring to the social network analysis) for studying the creativity traditionally associated with interpersonal contexts. Finally, the book includes perceptive analysis of the novel possibilities opened up by second-generation internet technologies, particularly in social networking, that seem destined to develop and sustain online creativity. As a wide-ranging exposition of a new direction in theoretical psychology that is laden with exciting possibilities, this volume will inform and inspire professionals, scholars and students alike. 124 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -Planning for the management of nuclear wastes -- whatever their level of radioactivity -- is one of the most important environmental problems for all societies that produce utility, industrial, medical, or other radioactive waste products. Attemps to site low-level radioactive waste disposal facilities in Western industrial societies, however, have repeatedly engendered conflicts between governments, encountered vehement opposition on the part of local citizen groups, and given rise to overt hostilities among involved parties. LLRW Disposal Facility Siting is the result of a study designed to learn more about the causes underlying failed and successful efforts to site LLRW disposal facilities. The study is based on case histories of LLRW disposal facility siting processes in six countries. Siting processes in five states within the United States and in five additional countries are analyzed using information obtained from public documents and supplemented by interviews with key participants. The selected states and countries are major generators of LLRW and each has made efforts to establish LLRW disposal facilities during the past decade. They vary widely in the approaches they have adopted to LLRW management, the institutional structures developed for managing the siting process, the means used to involve stakeholders and technical experts in the facility siting process and the amount and type of data used in making decisions. The analysis of these case histories provides general lessons about the advantages, disadvantages, strengths, and weaknesses of the various approaches that have been attempted or implemented. LLRW Disposal Facility Siting provides valuable data for academics and researchers working in the area of environmental management. 332 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -In the late 1980s, the field of comparative economics and NATO faced a similar problem: the threat of obsolescence. A predictable reaction of those who had made major investments in both comparative economics and NATO was to look for a new job. It was time to say: comparative economic systems are dead, long live comparative economic systems. The purpose of this book is to redirect study of what we called comparative economic systems toward analysis of the development of institutions and the effects of alternative institutional arrangements on economic performance. To that end, the book internalizes into a theoretical framework (1) the effects of alternative property rights on the costs of transactions and incentives structures, (2) the effects of the costs of transactions and incentives on economic behavior, and (3) the evidence for refutable implications of those effects. Analysis here focuses on the issues, propositions and conclusions that lend themselves to the only known scientific test: empirical verification. Thus, this book is not about what socialism or capitalism could have been, should have been, or should be. Nor is it an ode to capitalism. Its purpose is not to assert that capitalism is a better economic system than socialism. The history of this century and the market for institutions have done that. My purpose is to explain what is it that makes the institutions of capitalism better in terms of economic outcome than all other alternatives that have been tried since the beginning of recorded history. 240 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -THE EUROPEAN SINGLE MARKET This volume comprises a collection of papers, some of which were presented at different workshops organized by the European Economics and Financial Centre (London), in conjunction with various European central banks. In addition the book contains, in Chapter 2, the text of a memorial lecture on Trade and Financial Relationships of the US and Europe given by this author in New York. The lecture, known as the Henry George Lecture, was given at St John's University in New York in April 1993. The workshops were part of a series of workshops, the first of which was hosted by the Central Bank of Finland. At these workshops usually some 20 central banks from Europe, the Federal Reserve Board and various other central banks were present. Furthermore the workshops contain papers from international organizations such as the OECD, European Commission, Bank for International Settlement, government ministries, commercial banks, re search institutes and academics from Europe and elsewhere. The two workshops from which some of these papers were drawn were those held at the Central Bank of the Netherlands and the Central Bank of Austria. The workshop held at the Central Bank of the Netherlands (De Nederlandsche Bank), was on Policy Coordination, and took place during 2-4 November, 1992. The one held at the Central Bank of Austria (6stereichische Bank), was on Policy Formulation in Interdependent Market, and took place during 24-26 March 1993. 220 pp. Englisch.

Speakers came from every part of Europe, from N. America, and even from Australia, and almost all the papers presented are collected in this volume. They represent an important summary of the state of the art in libraries and information services in the medical and health areas and are a rich source of advice, assistance and information for everyone working in related fields. Most of the themes concentrate on the important growth areas of the profession: computer-based information services, networking (especially the Internet), and CD-ROMs. More general topics are not ignored, and the book contains many interesting contributions on identifying the needs of library users and evaluating how well these are being met. There is also an important section on the history of medicine. 300 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book contains a collection of papers on economic incentives and environmental policies which result from the authors' joint research work in the program `Environment, Science and Society', conducted under the auspices of the European Science Foundation, with whose cooperation the book has been published. The work concentrates on the scientific and methodological aspects of the development, implementation and evaluation of economic instruments at a national level. The research is both theoretical and empirical. At a theoretical level attention is given to the dynamics of instrument choice in various political and economic contexts, and to the means for evaluating economic instruments in terms of their effectiveness and efficiency. At an empirical level the research seeks to investigate the performance of economic instruments in reality and to explore options for new approaches on the interface between technology, economy and the environment. A subject index complements this first volume in the ESF `Environment, Science and Society' series. 320 pp. Englisch.

Flood, Jr. contains the proceedings of a conference held in honor of Robert P. Flood, Jr. Bob Flood has made important contributions to many areas of economic analysis, including regime switching, speculative attacks, bubbles, stock market volatility, macro models with nominal rigidities, dual exchange rates, target zones, and rules versus discretion in monetary policy. Contributors were invited to address any of the topics or others of their choosing. The results include five papers on topics in international finance; two of these papers, as well as the panel discussion, focus on speculative attacks and financial crises. The other three take new directions in exploring topics in which existing models leave much to be desired. 296 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -Following the presentation ofChina's Agenda XXIin 1994, the Fondazione Eni Enrico Mattei began a fruitful collaboration with the SSTC (State Science and Technology Commission) on Natural Resource Accounting of the People's Republic of China. Among other initiatives, the Fondazione organised a seminar held in Beijing in March 1996, entitled 'Resources Accounting in China'. This volume brings together 11 papers as the result ofthat seminar. Our main attempt was to compare approaches and knowledge of specific issues in this area. As far as the approach is concerned there appear to be some interesting comparisons to be drawn considering the authors' different fields of expenence. Seven papers are written by Chinese participants and four by visiting experts from the West. All the Chinese contributions point out the importance of the environment in economic development and a determination to measure the effects as a means to successful management of natural resources. They concentrate on rather specific issues within the constraints of the prevailing economic conditions where identification and pricing of assets tend to be specified by administrative norms. Although the general framework of the Chinese approach tends to be scientific and administrative, all papers contain interesting and useful statistical information. The papers by visiting experts also stress the importance of taking into account environmental aspects in deriving indicators relating to economic development. In contrast to the Chinese contributions, however, they tend to be more abstract and more clearly based on economic theory. 204 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -We conceived the idea for this book after teaching a graduate seminar on 'Habitat Complexity' at The University of South Florida. Discussions during the seminar led us to conclude that similar goals were to be found in studies of the topic that spanned the breadth of ecological research. Yet, the exact meaning of 'habitat structure', and the way in which it was measured, seemed to differ widely among subdisciplines. Our own research, which involves several sorts of ecology, convinced us that the differences among subdisciplines were indeed real ones, and that they did inhibit communica tion. We decided that interchange of ideas among researchers working in marine ecology, plant-animal interactions, physiological ecology, and other more-or-less independent fields would be worthwhile, in that it might lead to useful generalizations about 'habitat structure'. To foster this interchange of ideas. we organized a symposium to attract researchers working with a wide variety of organisms living in many habitats, but united in their interest in the topic of 'habitat structure'. The symposium was held at The University of South Florida's Chinsegut Hill Conference Center, in May. 1988. We asked participants to think about 'habitat structure' in new ways; to synthesize important, but fragmented, information; and. perhaps. to consider ways of translating ideas across systems. The chapters contained in this book reflect the participants' attempts to do so. The book is divided into four parts, by major themes that we have found useful categorizations. 456 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -It is now a well established tradition that every four years, at the end of winter, a group of 'celestial mechanicians' from all over the world gather at the 'Alpen gasthof Peter Rosegger' in the Styrian Alps (Ramsau, Austria). This time the colloquium was held from March 17 to March 23, 1996 and was devoted to the Dynamical Behaviour of our Planetary System. The papers covered a large range of questions of current interest: theoretical questions (re- nances, universal properties, non integrability, transport, . ) and questions about numerical tools ( symplectic maps, indicators of chaos, . ) were particularly well represented; the never ending problem of the sculpting of the asteroid belt was also qui te popular. You will find in the following pages a pot-pourri of what we listen to; you will miss of course the diversity of accents with which the tunes were delivered: from China, from Japan, from Brazil, from the United-States of America and from all over Europe, East and West. Let us not forget that the comet 199682 (Hyakutake) came to visit us; many an evening was spent on the deck of the Alpengasthof contemplating this celestial visitor who liked to play hide-and-seek behind the spruce trees. 444 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Image analysis is one of the most challenging areas in today's computer sci ence, and image technologies are used in a host of applications. This book concentrates on image textures and presents novel techniques for their sim ulation, retrieval, and segmentation using specific Gibbs random fields with multiple pairwise interaction between signals as probabilistic image models. These models and techniques were developed mainly during the previous five years (in relation to April 1999 when these words were written). While scanning these pages you may notice that, in spite of long equa tions, the mathematical background is extremely simple. I have tried to avoid complex abstract constructions and give explicit physical (to be spe cific, 'image-based') explanations to all the mathematical notions involved. Therefore it is hoped that the book can be easily read both by professionals and graduate students in computer science and electrical engineering who take an interest in image analysis and synthesis. Perhaps, mathematicians studying applications of random fields may find here some less traditional, and thus controversial, views and techniques. 268 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -The objectives of the ARW were: - identifying areas and highlighting approaches by which large Supramolecular (SM) Assemblies can be synthesised - reviewing and combining methods to characterise and analyse such assemblies. The first part of the ARW is devoted to reviewing synthetic achievements in recent years for several families of SM compounds, and to bringing out principles for crystal structure design, including novel quantum mechanical methods. Synthesis pertains both to the chemical synthesis of components for SM assembly, and to the subsequent assembly process based on complementarity and non-covalent interactions. The elaboration of multiple recognition 'algorithms' concurrently employed (for instance, 1t-1t and hydrogen bonds) has recently reached a high degree of sophistication in the sequence: Molecules -7 Supermolecule -7 SM array -7 Crystal or Conglomerate Novel Large Assemblies comprise synthetic entities with molecular weight as high as 15000, and hybrid SM assemblies between synthetic molecules and DNA. Further developments are foreseen at a higher level of organisation, such as between supermolecules or with electromagnetic fields in photochemical processes. Creation of 2D Assemblies is now a powerful tool for creation and study of SM interactions. Moreover, much is to be learned in going from 2D to 3D assemblies in crystal growth and other forms of organisation such as micelles or liquid crystals. On the other hand, crystal engineering based on Molecular Recognition in the Crystal State leads to novel 2D assemblies occurring within predesigned crystal structures (hydrophobic organic clays or nanoporous networks). 444 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -During the past three decades there has been a large amount of research on biological nitrogen fixation, in part stimulated by increasing world prices of nitrogen-containing fertilizers and environmental concerns. In the last several years, research on plant--microbe interactions, and symbiotic and asymbiotic nitrogen fixation has become truly interdisciplinary in nature, stimulated to some degree by the use of modern genetic techniques. These methodologies have allowed us to make detailed analyses of plant and bacterial genes involved in symbiotic processes and to follow the growth and persistence of the root-nodule bacteria and free-living nitrogen-fixing bacteria in soils. Through the efforts of a large number of researchers we now have a better understanding of the ecology of rhizobia, environmental parameters affecting the infection and nodulation process, the nature of specificity, the biochemistry of host plants and microsymbionts, and chemical signalling between symbiotic partners. This volume gives a summary of current research efforts and knowledge in the field of biological nitrogen fixation. Since the research field is diverse in nature, this book presents a collection of papers in the major research area of physiology and metabolism, genetics, evolution, taxonomy, ecology, and international programs. 216 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -Funding Science: An Immense Challenge The real challenge in science should be hypothesis formation, experimental design and conducting the actual research under rigorous control and experimental condi of tions with the best available equipment/infrastructure. However, in many parts the world, the real challenge in science is trying to obtain some minimal amount of funding to initiate research. Every country in the world is challenged with an im mense number of interconnected environmental and health problems. Examples in clude biologically and chemically contaminated water and soil, air pollution, waste and sewage treatment, a multitude of infectious diseases in humans, animals and plants, global change, population growth, alternate energy sources, deforestation, floods, crop production and so on. Solutions to these national and international problems require training and re search to ensure the best available people and knowledge are available to man age and/or solve these problems. This can only be accomplished if the research community has the funding to conduct priority research and apply the knowledge globally. The challenge in science should be discovering the unknown and col laborative research/training of new scientists. Too often the challenge is how to conduct research without proper support. Many scientists are likely of the opinion that it is not their jobs/careers that is stressful, but the inability to do their research properly, that is stressful. Good research in a knowledge based economy requires proper funding. 776 pp. Englisch.

RCONH )=r) o '' (I) 'C0 H 2 Penicillin was the first naturally occurring antibiotic to be characterised and used in clinical medicine. It is now seen as the progenitor of the tJ-Iactam family of antibiotics, which are characterised by the possession of the four membered tJ-Iactam ring. Chapters in this book will describe how current research has demonstrated that other lactam structures may also show antibacterial activity. Penicillins and cephalosporins (2), the second member of the tJ-Iactam antibiotic family, were both originally discovered in fungi but later detected in streptomycetes. Until 1970 penicillins and cephalosporins were the only examples of naturally occurring tJ-Iactam antibiotics. The discovery of 7-a-methoxy cephalosporins (3) from Streptomyces in 1971 stimulated the search for novel tJ-Iactam antibiotics from microbes, both by using sensitive new screening procedures, and by laboratory synthesis. 376 pp. Englisch.

New biologic mechanisms by which sex hormones may be detrimental or confer protection are continually being discovered. We are now starting to understand that the role of the estrogen receptor is not identical in all tissues. Important nongenomic effects for sex hormones have also been described. Hormone replacement therapy (HRT) has produced effects on health risks: some are reduced, some are increased, and the rest remain uncertain. HRT is being used by an increasing number of women to alleviate climacteric symptoms in the perimenopausal period and to prevent osteoporosis and cardiovascular disease later. Positive effects on Alzheimer's disease and dementia on the one hand, and an increase in venous thrombosis on the other, are currently being reported by several groups. Both the preventive benefits and the risk of breast cancer seem to be linked to long-term and current use. HRT requires further testing through specific clinical trials, currently underway in the United States, before confident recommendations may be made about the full range of benefits and risks. 376 pp. Englisch.

The book is subdivided into a total of eight parts, beginning with the more methodological issues, such as QCA and other modalities (3 chapters), cine film versus digital arteriography (3 chapters), quality control in QCA (4 chapters), and coronary blood flow and flow reserve (3 chapters). Since QCA has been well established as the technique for the assessment of regression and progression in atherosclerotic disease, and of restenosis after recanaliz ation procedures, major clinical trials in both groups are described extensively by their principal investigators in a total of 11 chapters. In addition, the QCA results after the application of various recanalization techniques are presented in another eight chapters. In the last part the experiences with various intracoronary prostheses with the emphasis on QCA are discussed in five chapters. This large increase in application oriented chapters means that QCA is well alive and gaining momentum. Although the accuracy and precision of the analytical methods steadily improve with the increasing complexity of the algorithms, there is still always the human factor involved in these processes in terms of frame selection, segment definition, etc. 660 pp. Englisch.

The treatment of upper tract renal stone has progressed from the days of a very traumatic and morbid procedure to the relatively innocuous, walk in/walk out therapy of extracorporeal lithotripsy. This progression of events has resulted in a complete reappraisal of management of all types of urinary calculi. From an initial reluctance to treat many stones because of the trauma involved, we have now passed to a situation where smaller and asympto matic stones may be pre-emptively treated before the treatment of serious clinical problems. It is true to say that in Westemized societies the problem of urolithiasis has almost completely been solved by the advent of advanced technology. In this volume, attention is drawn to the fact that there are still persistent difficulties in treating urolithiasis in the less developed and less affluent societies. The differences in epidemiology of urolithiasis in various areas of the world are highlighted, noting a rapid decrease in the incidence of bladder calculi in impover ished areas where affluence increases. Coupled with this progression of affluence however is the well documented increase in the incidence of upper tract renal stones of oxalate nature. This scenario has been almost universal across all coun tries in the last few decades. 376 pp. Englisch.
