Buch. Condizione: Neu. Neuware -Sexual risk behaviors have inspired profound ideas and effective teamwork. But as the early history of AIDS demonstrates, when sexual practice is part of the equation, the same bold thinkers may be stymied, or just silent. Safe sex and monogamy have been proposed as answers to a gamut of social problems, but there is frequently little consensus on what these terms mean.Sexual Partnering, Sexual Practices, and Health replaces myth and stereotype with meticulously documented findings on real people and their behaviors in their social, environmental, and individual contexts. Author Sana Loue examines the range of partnerships not only in the U.S. but also Europe and the developing world, focusing on both consenting relationships and exploitative sexual interactions: Varieties of monogamy between consenting adults Relationships involving multiple adult partners Incest, pedophilia, and child marriage Sex work, trafficking, and pornography Fetishes and related behaviorsAll chapters cogently address the health issues that arise from these arrangements, concluding with implications for research, prevention, and intervention.Throughout, Loue argues for a common language across disciplines and challenges her readers¿therapists, health care providers, and policymakers alike¿to rethink their assumptions about clients, their health needs, and the communities they represent.'Dr. Loue's work is a truly significant scholarly contribution to a topic too often characterized by pseudo-science and ideological distortions. 'Sexual Partnering, Sexual Practices, and Health' should prove an invaluable resource for researchers and community practitioners alike in helping understand dimensions of sexual practice, and designing more effective approaches to sexual health and violence prevention.'Earl Pike, Executive Director, AIDS Taskforce of Greater ClevelandSpringer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 212 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -It is intended that this book be used in senior- to graduate-level semester courses in optimization, as offered in mathematics, engineering, com puter science and operations research departments. Hopefully this book will also be useful to practising professionals in the workplace. The contents of the book represent the fundamental optimization mate rial collected and used by the author, over a period of more than twenty years, in teaching Practical Mathematical Optimization to undergradu ate as well as graduate engineering and science students at the University of Pretoria. The principal motivation for writing this work has not been the teaching of mathematics per se, but to equip students with the nec essary fundamental optimization theory and algorithms, so as to enable them to solve practical problems in their own particular principal fields of interest, be it physics, chemistry, engineering design or business eco nomics. The particular approach adopted here follows from the author's own personal experiences in doing research in solid-state physics and in mechanical engineering design, where he was constantly confronted by problems that can most easily and directly be solved via the judicious use of mathematical optimization techniques. This book is, however, not a collection of case studies restricted to the above-mentioned specialized research areas, but is intended to convey the basic optimization princi ples and algorithms to a general audience in such a way that, hopefully, the application to their own practical areas of interest will be relatively simple and straightforward.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 280 pp. Englisch.

Buch. Condizione: Neu. Neuware -A research focus on hazards, risk perception and risk minimizing strategies is relatively new in the social and environmental sciences. This volume by a prominent scholar of East African societies is a powerful example of this growing interest. Earlier theory and research tended to describe social and economic systems in some form of equilibrium. However recent thinking in human ecology, evolutionary biology, not to mention in economic and political theory has come to assign to 'risk' a prominent role in predictive modeling of behavior. It turns out that risk minimalization is central to the understanding of individual strategies and numerous social institutions. It is not simply a peripheral and transient moment in a group¿s history. Anthropologists interested in forager societies have emphasized risk management strategies as a major force shaping hunting and gathering routines and structuring institutions of food sharing and territorial behavior. This book builds on some of these developments but through the analysis of quite complex pastoral and farming peoples and in populations with substantial known histories. The method of analysis depends heavily on the controlled comparisons of different populations sharing some cultural characteristics but differing in exposure to certain risks or hazards.The central questions guiding this approach are: 1) How are hazards generated through environmental variation and degradation, through increasing internal stratification, violent conflicts and marginalization 2) How do these hazards result in damages to single households or to individual actors and how do these costs vary within one society 3) How are hazards perceived by the people affected 4) How do actors of different wealth, social status, age and gender try to minimize risks by delimiting the effect of damages during an on-going crisis and what kind of institutionalized measures do they design to insure themselves against hazards, preventing theiroccurrence or limiting their effects 5) How is risk minimization affected by cultural innovation and how can the importance of the quest for enhanced security as a driving force of cultural evolution be estimated Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 472 pp. Englisch.

Buch. Condizione: Neu. Neuware -System Level Design of Reconfigurable Systems-on-Chip provides insight in the challenges and difficulties encountered during the design of reconfigurable Systems-on-Chip (SoCs). Reconfiguration is becoming an important part of System-on-Chip design to cope with the increasing demands for simultaneous flexibility and computational power.The book focuses on system level design issues for reconfigurable SoCs, and provides information on reconfiguration aspects of complex SoCs and how they can be implemented in practice. It is divided in three parts. The first part provides background information and requirements on reconfigurable technologies and systems. The second one identifies existing methodological gaps, and introduces a design flow for developing reconfigurable Systems-on-Chip. The high level part of the design flow can be covered by two C++ based methodologies: one based on SystemC and one based on OCAPI-XL, both including appropriate extensions to handle reconfiguration issues. Finally, the third part of the book presents reconfigurable SoCs from the perspective of the designer, through three indicative case studies from the wireless and multimedia communication domain.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 232 pp. Englisch.

Buch. Condizione: Neu. Neuware -Atomic Spectroscopy provides a comprehensive discussion on the general approach to the theory of atomic spectra, based on the use of the Lagrangian canonical formalism. This approach is developed and applied to explain the hydrogenic hyperfine structure associated with the nucleus motion, its finite mass, and spin. The non-relativistic or relativistic, spin or spin-free particle approximations can be used as a starting point of general approach. The special attention is paid to the theory of Lamb shift formation. The formulae for hydrogenic spectrum including the account of Lamb shift are written in simple analytical form. The book is of interest to specialists, graduate and postgraduate students, who are involved into the experimental and theoretical research in the field of modern atomic spectroscopy.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 292 pp. Englisch.

Buch. Condizione: Neu. Neuware -The area of similarity searching is a very hot topic for both research and c- mercial applications. Current data processing applications use data with c- siderably less structure and much less precise queries than traditional database systems. Examples are multimedia data like images or videos that offer query by example search, product catalogs that provide users with preference based search, scientific data records from observations or experimental analyses such as biochemical and medical data, or XML documents that come from hetero- neous data sources on the Web or in intranets and thus does not exhibit a global schema. Such data can neither be ordered in a canonical manner nor meani- fully searched by precise database queries that would return exact matches. This novel situation is what has given rise to similarity searching, also - ferred to as content based or similarity retrieval. The most general approach to similarity search, still allowing construction of index structures, is modeled in metric space. In this book. Prof. Zezula and his co authors provide the first monograph on this topic, describing its theoretical background as well as the practical search tools of this innovative technology.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 240 pp. Englisch.

Buch. Condizione: Neu. Neuware -This book provides a review of image analysis techniques as they are applied in the field of diagnostic and therapeutic nuclear medicine. Driven in part by the remarkable sophistication of nuclear medicine instrumentation and - crease in computing power and its ready and inexpensive availability, this is a relatively new yet rapidly expanding field. Likewise, although the use of nuclear imaging for diagnosis and therapy has origins dating back almost to the pioneering work of Dr G. de Hevesy, quantitative imaging has only recently emerged as a promising approach for diagnosis and therapy of many diseases. An effort has, therefore, been made to place the reviews provided in this book in a broader context. The effort to do this is reflected by the inclusion of introductory chapters that address basic principles of nuclear medicine instrumentation and dual-modality imaging, followed by overview of issues that are closely related to quantitative nuclear imaging and its potential role in diagnostic and therapeutic applications. A brief overview of each chapter is provided below. Chapter 1 presents a general overview of nuclear medicine imaging physics and instrumentation including planar scintigraphy, single-photon emission computed tomography (SPECT) and positron emission tomography (PET). Nowadays, patients¿ diagnosis and therapy is rarely done without the use of imaging technology. As such, imaging considerations are incorporated in almost every chapter of the book. The development of dual-modality - aging systems is an emerging research field, which is addressed in chapter 2.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 596 pp. Englisch.

Buch. Condizione: Neu. Neuware -Having spent almost fifty years of my life defending the separate accou- ing, arm's length pricing method, I have to admit that I was somewhat surprised to be asked to contribute to a book suggesting that the European Union might do well to consider adopting a formulary approach to deal with the taxation of inter and intra company transactions. I was even more surprised to see the invitation coming from Ms. Joann Weiner an ardent co-defender of arm's length pricing and my strong right arm in that regard while we both served in the U.S. Treasury Department in the mid '90s. The book gives Ms Weiner the opportunity to comment frankly from an insider's perspective of the many admitted problems of the arm's length system which could be avoided by a formulary approach. Ms. Weiner brings to this project a thorough expert knowledge of the b- efits and shortfalls of each of the systems she discusses - separate accounting v. formulary apportionment. Who better to decide to give qualified support to formulary than someone who organized a U.S. Treasury conference to defend arm's length pricing against a Congressional challenge in favor of formulary apportionment.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 144 pp. Englisch.

Buch. Condizione: Neu. Neuware - Separation of the elements of classical mechanics into kinematics and dynamics is an uncommon tutorial approach, but the author uses it to advantage in this two-volume set. Students gain a mastery of kinematics first a solid foundation for the later study of the free-body formulation of the dynamics problem.A key objective of these volumes, which present a vector treatment of the principles of mechanics, is to help the student gain confidence in transforming problems into appropriate mathematical language that may be manipulated to give useful physical conclusions or specific numerical results. In the first volume, the elements of vector calculus and the matrix algebra are reviewed in appendices. Unusual mathematical topics, such as singularity functions and some elements of tensor analysis, are introduced within the text. A logical and systematic building of well-known kinematic concepts, theorems, and formulas, illustrated by examples and problems, is presented offering insights into both fundamentals and applications. Problems amplify the material and pave the way for advanced study of topics in mechanical design analysis, advanced kinematics of mechanisms and analytical dynamics, mechanical vibrations and controls, and continuum mechanics of solids and fluids.Volume I of Principles of Engineering Mechanics provides the basis for a stimulating and rewarding one-term course for advanced undergraduate and first-year graduate students specializing in mechanics, engineering science, engineering physics, applied mathematics, materials science, and mechanical, aerospace, and civil engineering. Professionals working in related fields of applied mathematics will find it a practical review and a quick reference for questions involving basic kinematics.

Buch. Condizione: Neu. Neuware -Intuitive Probability and Random Processes using MATLAB® is an introduction to probability and random processes that merges theory with practice. Based on the author¿s belief that only 'hands-on' experience with the material can promote intuitive understanding, the approach is to motivate the need for theory using MATLAB examples, followed by theory and analysis, and finally descriptions of 'real-world' examples to acquaint the reader with a wide variety of applications. The latter is intended to answer the usual question 'Why do we have to study this ' Other salient features are:\*heavy reliance on computer simulation for illustration and student exercises\*the incorporation of MATLAB programs and code segments\*discussion of discrete random variables followed by continuous random variables to minimize confusion\*summary sections at the beginning of each chapter\*in-line equation explanations\*warnings on common errors and pitfalls\*over 750 problems designed to help the reader assimilate and extend the conceptsIntuitive Probability and Random Processes using MATLAB® is intended for undergraduate and first-year graduate students in engineering.

Buch. Condizione: Neu. Neuware - The Economics of Persistent Innovation presents papers that provide definitions of persistence in firm innovative behavior, establish the significance of persistence, present a theory of persistence, and examine empirical evidence regarding both the extent of, and the determinants of, persistence. They survey previous studies which have commented on persistence and present new data describing trends in the persistence in innovation. The book discusses the main determinants of persistence and the reasons for its systematic heterogeneity across industries, technologies and countries. The book first focuses on the determinants of persistence in innovation. This topic is analyzed in several ways, including a Markovian model of innovation. The characteristics of persistent inventors as revealed in patent data are explored for many industrial countries. An evolutionary theory of persistence in innovation is proposed. In conclusion we draw some policy implications for support and development of innovation.

Buch. Condizione: Neu. Neuware -This book was prepared for publication by an International Working Group of experts under the auspices of COGEOENVIRONMENT - the Commission of the International Union of Geological Sciences (lUGS) on Geological Sciences for Environmental Planning and lUGS-GEM (Commission on Geosciences for Environmental Management). The main aim of the Working Group 'Geology and Ecosystems' was to develop an interdisciplinary approach to the study of the mechanisms and special features within the 'living tissue - inert nature' system under different regional, geological, and anthropogenic conditions. This activity requires international contributions from many scientific fields. It requires efforts from scientists specializing in fields such as: environmental impacts of extractive industries, anthropogenic development and medical problems related to geology and ecosystem interaction, the prediction of the geoenvironmental evolution of ecosystems, etc. The Working Group determined the goal and objectives of the book, developed the main content, discussed the parts and chapters, and formed the team of authors and the Editorial Board. The Meetings of the Working Group (Vilnius, Lithuania, 2002 and Warsaw-Kielniki, Poland, 2003) were dedicated to discussion and approval of the main content of all chapters in the Book.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 420 pp. Englisch.

Buch. Condizione: Neu. Neuware -Scaling transistors into the nanometer regime has resulted in a dramatic increase in MOS leakage (i.e., off-state) current. Threshold voltages of transistors have scaled to maintain performance at reduced power supply voltages. Leakage current has become a major portion of the total power consumption, and in many scaled technologies leakage contributes 30-50% of the overall power consumption under nominal operating conditions. Leakage is important in a variety of different contexts. For example, in desktop applications, active leakage power (i.e., leakage power when the processor is computing) is becoming significant compared to switching power. In battery operated systems, standby leakage (i.e., leakage when the processor clock is turned off) dominates as energy is drawn over long idle periods. Increased transistor leakages not only impact the overall power consumed by a CMOS system, but also reduce the margins available for design due to the strong relationship between process variation and leakage power. It is essential for circuit and system designers to understand the components of leakage, sensitivity of leakage to different design parameters, and leakage mitigation techniques in nanometer technologies. This book provides an in-depth treatment of these issues for researchers and product designers.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 320 pp. Englisch.

Buch. Condizione: Neu. Neuware -The last 15 years in development of biology were marked with accumulation of unprecedentedly huge arrays of experimental data. The information was amassed with exclusively high rates due to the advent of highly efficient experimental technologies that provided for high throughput genomic sequencing; of functional genomics technologies allowing investigation of expression dynamics of large groups of genes using expression DNA chips; of proteomics methods giving the possibility to analyze protein compositions of cells, tissues, and organs, assess the dynamics of the cell proteome, and reconstruct the networks of protein-protein interactions; and of metabolomics, in particular, high resolution mass spectrometry study of cell metabolites, and distribution of metabolic fluxes in the cells with a concurrent investigation of the dynamics of thousands metabolites in an individual cell. Analysis, comprehension, and use of the tremendous volumes of experimental data reflecting the intricate processes underlying the functioning of molecular genetic systems are unfeasible in principle without the systems approach and involvement of the state-of-the-art information and computer technologies and efficient mathematical methods for data analysis and simulation of biological systems and processes. The need in solving these problems initiated the birth of a new science¿ postgenomic bioinformatics or systems biology in silico.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 576 pp. Englisch.

Buch. Condizione: Neu. Neuware -'From nothing I have created a new different world,' wrote János Bolyai to his father, Wolgang Bolyai, on November 3, 1823, to let him know his discovery of non-Euclidean geometry, as we call it today. The results of Bolyai and the co-discoverer, the Russian Lobachevskii, changed the course of mathematics, opened the way for modern physical theories of the twentieth century, and had an impact on the history of human culture.The papers in this volume, which commemorates the 200th anniversary of the birth of János Bolyai, were written by leading scientists of non-Euclidean geometry, its history, and its applications. Some of the papers present new discoveries about the life and works of János Bolyai and the history of non-Euclidean geometry, others deal with geometrical axiomatics; polyhedra; fractals; hyperbolic, Riemannian and discrete geometry; tilings; visualization; and applications in physics.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 524 pp. Englisch.

Buch. Condizione: Neu. Neuware -A link between inflammation and cancer has been established many years ago, yet it is only recently that the potential significance of this connection has become apparent. Although several examples of chronic inflammatory conditions, often induced by persistent irritation and/or infection, developing into cancer have been known for some time, there has been a notable resistance to contemplate the possibility that this association may apply in a causative way to other cancers. Examples for such progression from chronic inflammation to cancer are colon carcinoma developing with increased frequency in patients with ulcerative colitis, and the increased incidence of bladder cancer in patients suffering from chronic Schistosoma infection. Inflammation and cancer have been recognized to be linked in another context for many years, i.e., with regards to pathologies resembling chronic lacerations or 'wounds that do not heal.' More recently, the immunology of wound healing has given us clues as to the mechanistic link between inflammation and cancer, in as much as wounds and chronic inflammation turn off local cell-mediated immune responses and switch on growth factor release as well the growth of new blood vessels - angiogenesis. Both of these are features of most types of tumours, which suggest that tumours may require an immunologically shielded milieu and a growth factor-rich environment.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 268 pp. Englisch.
