Taschenbuch. Condición: Neu. Neuware - Members of the gastropod family Littorinidae are common throughout the world. They form a very abundant component of many intertidal and shallow subtidal ecosystems and, by their grazing, often play a central role in shaping these communities. They also display a wide range of life history strategies and many are polymorphic, making them attractive model organisms for ecologists, evolutionary biologists and physiologists alike. Areas of particular interest include ecological interactions with other animals and with algae, the effects of pollutants and the use of littorinids as sentinel species for monitoring pollution, the effects of parasites on growth and ecology, taxonomy, and the study of genotypic/phenotypic responses to environmental factors. There is still much to be done, and the littorinids are proving to be an ideal group on which to work. Audience: Primarily targeted at the research level. Will also provide useful information for advanced first-degree students conducting research projects.

Buch. Condición: Neu. Neuware - The International Handbook of Research in Professional and Practice-based Learning discusses what constitutes professionalism, examines the concepts and practices of professional and practice-based learning, including associated research traditions and educational provisions. It also explores professional learning in institutions of higher and vocational education as well the practice settings where professionals work and learn, focusing on both initial and ongoing development and how that learning is assessed.The Handbook features research from expert contributors in education, studies of the professions, and accounts of research methodologies from a range of informing disciplines. It is organized in two parts. The first part sets out conceptions of professionalism at work, how professions, work and learning can be understood, and examines the kinds of institutional practices organized for developing occupational capacities. The second part focuses on procedural issues associated with learning for and through professional practice, and how assessment of professional capacities might progress. The key premise of this Handbook is that during both initial and ongoing professional development, individual learning processes are influenced and shaped through their professional environment and practices. Moreover, in turn, the practice and processes of learning through practice are shaped by their development, all of which are required to be understood through a range of research orientations, methods and findings. This Handbook will appeal to academics working in fields of professional practice, including those who are concerned about developing these capacities in their students. In addition, students and research students will also find this Handbook a key reference resource to the field.

Frisch, who in his publications 'Correlation and Scatter Analysis in Statistical Variables' (1929) and 'Statistical Confluence Analysis by means of Complete Regression Systems' (1934) first pointed out the complications that arise if one applies regression analysis to variables among which several independent linear relations exist. Should these relationships be exact, then there exist two closely related solutions for this problem, viz. 1. The estimation of 'stable' linear combinations of coefficients, the so-called estimable functions. 2. The dropping of the wen-known condition of unbiasedness of the estimators. This leads to minimum variance minimum bias estimators. This last solution is generalised in this book for the case of a model consisting of several equations. In econometrics however, the relations among variables are nearly always approximately linear so that one cannot apply one of the solutions mentioned above, because in that case the matrices used in these methods are, although ill-conditioned, always of full rank. Approximating these matrices by good-conditioned ones of the desired rank, it is possible to apply these estimation methods. In order to get an insight in the consequences of this approximation a simulation study has been carried out for a two-equation model. Two Stage Least Squares estimators and estimators found with the aid of the above mentioned estimation method have been compared. The results of this study seem to be favourable for this new method. 112 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book deals with the relationship between gravitation and elementary particle physics, and the implications of these subjects for astrophysics. There has, in recent years, been renewed interest in theories that connect up gravitation and particle physics, and in the astrophysical consequences of such theories. Some of these accounts involve a time-variation of the Newtonian gravitational parameter, G. In this respect, the present book may be regarded as a companion to my Cosmology and Geophysics (Hilger, Bristol, 1978). There is some overlap as regards the discussion of G-variability, but the emphasis in the present book is on astrophysics while the emphasis in the other one is on geophysics. The subject is a very broad one indeed, and in giving a review of it I have adopted a somewhat unorthodox way of presenting the material involved. The main reason for this is that a review of such a wide subject should aim at two levels: the level of the person who is interested in it, and the level of the person who is professionally engaged in research into it. To achieve such a two-level coverage, I have split the text up into two parts. The first part (Chapters 1-7) represents a relatively non-technical overview of the subject, while the second part (Chapters 8-11) represents a technical examination of the most important aspects of non-Einsteinian gravitational theory and its relation to astrophysics. 204 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The theory of nonlinear oscillations and stability of motion is a fundamental part of the study of numerous real world phenomena. These phenomena, particularly auto-oscillations of the first and second kind, capture, para metric, subharmonic and ultraharmonic resonance, asymptotic behavior and orbits' stability, constitute the core of problems treated in 'Nonlinear Mechanics', and their study is connected with the names of H. Poincare, A. M. Lyapunov, N. M. Krylov and N. N. Bogolyubov. Professor Demetrios Magiros, a widely known scientist in the theories of oscillations and nonlinear differential equations, has devoted his numerous works to this significant part of modern physical science. His scientific results can be classified in the following way: I) creation of methods of analysis of subharmonic resonances under the nonlinear effect, 2) determination and analysis of the main modes of nonlinear oscillations on the basis of infinite determinants, 3) analysis of problems of celestial mechanics, 4) classification of stability of solutions of dynamic systems concepts, 5) mathematical analogs of physical and social systems. He has developed new methods and solutions for a great number of difficult problems of nonlinear mechanics making a significant contri bution to the theory and applications of the field. Urgency, depth of perception of the considered phenomena, and practi cal directness are characteristics of his work. 540 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -There are many natural hazards such as floods, landslides, volcanoes and earthquakes in the Asia-Pacific Region. Nevertheless, there are few studies of such natural hazards in this region and knowledge about their mitigation is of the utmost importance. This book documents the use of geomorphological maps showing the state of flooding; these maps allow predictions to be made. The author has compiled geomorphological maps and documentation of their validation, and the maps allow not only estimation of flooding, but also prediction of soil liquefaction caused by earthquakes. Audience: The results of the discussions in this book apply not only to geographers, consultants, engineers and policy makers in Japan and Southeast Asian countries, but also to those from Europe, North America, and Africa. 192 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The basic partial differential equations for the stresses and displacements in clas sical three dimensional elasticity theory can be set up in three ways: (1) to solve for the displacements first and then the stresses; (2) to solve for the stresses first and then the displacements; and (3) to solve for both stresses and displacements simultaneously. These three methods are identified in the literature as (1) the displacement method, (2) the stress or force method, and (3) the combined or mixed method. Closed form solutions of the partial differential equations with their complicated boundary conditions for any of these three methods have been obtained only in special cases. In order to obtain solutions, various special methods have been developed to determine the stresses and displacements in structures. The equations have been reduced to two and one dimensional forms for plates, beams, and trusses. By neglecting the local effects at the edges and ends, satisfactory solutions can be obtained for many case~. The procedures for reducing the three dimensional equations to two and one dimensional equations are described in Chapter 1, Volume 1, where the various approximations are pointed out. 740 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -G.I.N. Rozvany ASI Director, Professor of Structural Design, FB 10, Essen University, Essen, Germany Structural optimization deals with the optimal design of all systems that consist, at least partially, of solids and are subject to stresses and deformations. This inte grated discipline plays an increasingly important role in all branches of technology, including aerospace, structural, mechanical, civil and chemical engineering as well as energy generation and building technology. In fact, the design of most man made objects, ranging from space-ships and long-span bridges to tennis rackets and artificial organs, can be improved considerably if human intuition is enhanced by means of computer-aided, systematic decisions. In analysing highly complex structural systems in practice, discretization is un avoidable because closed-form analytical solutions are only available for relatively simple, idealized problems. To keep discretization errors to a minimum, it is de sirable to use a relatively large number of elements. Modern computer technology enables us to analyse systems with many thousand degrees of freedom. In the optimization of structural systems, however, most currently available methods are restricted to at most a few hundred variables or a few hundred active constraints. 1244 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -'How am I concerned about the environment from where I stand professionally ' Or, 'what is the environmental edge of my profession ' A number of outstanding academics were asked to consider these questions in 1989 with the aim of opening an innovative discussion on environmental changes and an understanding of how these are related to human activities. At the personal invitation of the Programme Committee, 17 individuals, each of whom have different professional backgrounds and nationalities, prepared a paper and met for a symposium in Elsinore, Denmark, in September of 1990. Some of the authors revised their original papers as a result of the discussions during the symposium. After peer review and editing, the contributions were printed in this book in versions that express the authors' personal convictions and priority environmental concerns. The authors contributed to the symposium by delivering papers and participat ing in stimulating and sometimes provocative discussions. The Programme Committee is grateful for the professional inspiration provided and for the spiritual and warm, social atmosphere in which the symposium took place. 308 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Several ofthe themes of this study have been treated in earlier publica tions, some by means of a general analysis and some through a detailed handling of problems raised by a particular theme or historian. Both the more general theoretical treatment of the theme and the concrete historiographical treatment are, I think, indispensable aids to the proper understanding of the development of historical scholarship in nineteenth-and twentieth-century England. There are a number of problems in a concrete historiographical approach: there is first the mass of historians to be faced, and then the immense amount of historical themes dealt with in various periods. As a guideline through the tangle of themes we chose the historiography on the development of the English parliament. We can only hope that we have made a responsible choice of the historians concerned. Un fortunately it was not always possible for us to give extensive biogra phies of some of the more recent historians, as several 'papers' are still firmly in the possession of families, and a number of them mus- despite of years - still be labelled 'confidential.' The Pollard Papers in the London Institute of Historical Research thus remained inaccessible. Fortunately the lack was partly compen sated by some important material being found apart from these Papers. 464 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -1t gives me great pleasure as Chairman of the Section on Business Law to write a foreword to this, the second volume in a series of books on Maritime Law. Volume I dealt with 'Arrest of Vessels' and the remain ing subjects tobe covered are 'Mortgages of Vessels' and 'Registration of Vessels'. The first volume has proved most successful and many lawyers have testified to its practical value. I am certain that this second volume will have an equally warm welcome. The series is the inspiration of Lennart Hagberg, the Chairman of the Section on Business Law's Committee on Maritime and Transport Law. Both he, and the contributors to the series who are all members of that Committee, are busy practising lawyers, and it is only by making sacrifices that they have been able to add this additional task to their already heavy commitments. In particular, Lennart Hagberg's task as editor has involved an enormous amount of work and I am most grateful to him and bis fellow-contributors for all that they have done. May I wish this Book and those following it every success. 116 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -There is little need today for an author publishing a work on less developed countries to emphasise the importance of this question. In view of the large and increasing number of publications on this subject - and in fairness to the reader - it seems appropriate, however, to outline briefly what the book sets out to describe. As the title conveys, I have concentrated on the financial side of the problem without neglecting altogether the important political, social and human aspects. I have primarily dealt with the problems of capital formation, capital transfer, capital employment and the associated balance of payments considerations. The attempt is made to set out in an integrat ed analysis the problems of capital exports to less developed countries both from the point of view of the creditor and of the debtor, be they countries or individuals. This method appeared all the more appropriate since the provision oflong term funds for capital exports and the question of their employment in the capital importing countries are so closely interconnected that they could hardly be treated separately. 176 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This brief fills a gap in the studies of organized crime in Mexico (Kan 2012, Ríos 2011, Dell 2011) by documenting and mapping the post-2008 assassination of Mexican border police chiefs. It traces out a 'systematic' of law-enforcement assassination in Northern Tier Mexico, showing how the selective, often sequential, hits by cartels on chiefs in border towns and along key drug-trafficking corridors has proven an effective strategy by organized crime elements to serve several goals: (1) to retaliate for federal, state and local prosecution, (2) to try and neutralize police chiefs, (3) to achieve intermittent local governance and/or to seed corrupt police chiefs at the municipal level, and, (4) to reduce local governmental capacity to obtain greater freedom for movement of goods. It is argued that the tactical advantage of organized crime elements gives them relatively easy physical access to law enforcement targets and thus is thus one prime element facilitating the use of assassination as a strategy. U.S. and Mexican legal, political and judicial institutions have not been able to adequately restrict opportunity for law-enforcement assassinations. The inability to reduce access to weapons and officials, to increase security for police personnel, to reduce corruption and punish offenders sets the stage for the assassination of local law enforcement. Yet, it is the goals of organized crime elements (to clear drug-smuggling routes and to try and gain more pliant governance at the municipal level) that ultimately motivate such killings. 128 pp. Englisch.

Buch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book offers innovative insights on South-South human mobility. It features a collection of papers that highlight often overlooked mobility patterns among and within regions in the global South as well as address critical realities faced by South-South migrants. This publication thoroughly investigates key issues of the migration debate, spanning from the terminological and contextual meaning of migration and development. It also critically examines some of the key features that human mobility in the global South is characterized by, including the prevalence of intra-regional and labor mobility, the role of diasporas communities in developing countries, South-South remittances patterns, the influence of environmental factors on the decision to migrate and the rising number of child migrants.By carefully moving the lens from the frequently examined South-North and North-North movements to human mobility within the Southern regions of the world, this book questions the traditional conception of the migration paradigm. It offers knowledge and insights that will help to expand the debate as well as stimulate further research on this important topic and, hopefully, promote future activities aimed at the protection of migrants and their families living in the South. As a result, it is an ideal resource for migration scholars, policy-makers and development practitioners. 188 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The essays in this volume are timelyand provocative. They address the key issues of the changing world economy and consider the implications ofthe erosion ofthe rule oflaw that has occurred both domestically and internationally to an increasing degree over the past halfcentury. The debates over the role of the dollar in the international econ omy, the future shape ofthe international monetary system and the exchange rate regime, the significance ofthe U. S. twin deficits, and the rise of nontariffbarriers to world trade deserve serious attention. Atthe bottom ofthese debates lie differing conceptions ofeconomic policy and the role of government in a free society. Adam Smith's vision ofa limited democracy operating to protect persons and prop erty has been increasinglyreplaced by a vision ofapaternalistic state that is designed to protect special interests at the expense of the larger society. Many of the contributors to this volume point to the lack oflong-run rules designed to promote sound money, fiscal integ rity, and open markets asthe fundamental flawofmodern democratic governments. Although the authors disagree on the specific rules to adopt, the consensus is that a constitutional perspective is needed to ensure astable worldorder. Moreover,since such aperspective must bedeveloped at home before it can spread among nations,the search for optimal international policy coordination is generally seen as misguided. Many ofthe essays in this volume were initially presented at the Cato Institute's Sixth Annual Monetary Conference held in Wash ington, D. C. , February 25-26, 1988. 456 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -The present publication of re ports and discussions sterns from the fourth Session of the Hague-Zagreb Colloquium, held at Eernewoude, in the Netherlands. The preceding three Sessions were held at Stubice Toplice, in Yugoslavia (1974), Zeist, in the Netherlands (1976) and, again in Yugoslavia, at Opatija (1978). The fourth Session was originally planned for May 1980. On the eve of the meeting, the then President of the Socialist Federal Republic of Yugoslavia, the late Marshall J .B. Tito, passed away. On hearing the news of the Marshall's death, the Organizing Committee of the Hague-Zagreb Colloquium immediately decided that the Session should not then be held. The postponement lasted, in fact, a whole year: the fourth Session was convened at Eernewoude in May 1981. For the Eernewoude Session the formula that had produced such excellent results in the previous conferences was maintained. Four topics of international trade law were thoroughly discussed on the basis of reports submitted by scholars from the various legal systems represented at the conference. Apart from the Yugoslav and Dutch participants, scholars from the United Kingdom, the Federal Republic of Germany, Belgium and Norway took part in the discussions, be it in the capacity of reporter, of chairman or as expert in the field covered by the Colloquium: the law of international trade. A student competition had again been organised and the members of the win ning teams from Yugoslavia and from the Netherlands were among the participants. 416 pp. Englisch.

Calling it a fundamental fault, indeed, tacitly begs the question: Is there one fundamental fault, or are there several that are interlinked or interdependent A simple yes or no answer cannot be offered. This volume is not designed to survey the up-to-date recent advances in research on hypertension, nor intended to provide provisional an swers to the so many unknowns in this topic. It is, in fact, an attempt to articulate questions that are worth asking, given the license of an unhibited, albeit disci plined, inquiry. The range of expression varies from dogmatic opinion to a declared speculation. Is the primary abnormality an excessive sodium and reduced potassium intake over generations Or is it hormonal excess, deficiency, imbalance or altered synthesis of abnormal forms Does the nervous system playa role of active initiation or only of passive maintenance in the genesis of hypertension Is the heart only a pump acting in concert with the happenings to the vasculature trying to provide adequate flow in the face of vasconstriction induced by neural or humoral factors, or does it sometimes become the culprit by pumping blood flow in excess of demand and thus initiating hypertrophic changes in blood vessels, or by assuming the role of an endocrine organ and being the source of a hormone with influence on cellular transport of sodium and on vasomotor tone Is an elusive and mysterious fault in the kidney, the primary basis of all of the above 360 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Peter B. Senholzi Manager, Applications Engineering Mechanical Technology Incorporated In most discussions concerning tribology, authors felt compelled to introduce the topic by first defining the term. In this discussion, however, the term will not be defined until after the circumstances that spawned its existence have been summarized. This discussion will revolve around two facets of mechanical system design, that of structural integrity and wear integrity. In the not too distant past, the evolutionary process of machine design had in most cases attained a stage of development where the structural integrity of a system was ensured. Simply stated, this means that the machine components would not 'break. ' However, at this development phase, little emphasis was placed on component wear integrity. This meant that although machinery components would not break, they would be subject to high wear/wear-out rates. Frequent component replacements were used in order to compensate for this situation. A 'throw away' philosophy was thus adopted. This philosophy, however, resulted in many undesirable secondary effects. Mechanical systems were characterized by expensive logistics, costly maintenance, limited availability, limited lives, and substantial energy consumption. This energy consumption resulted from primary effects of high equipment frictional levels {causing the high wear rate) and such secondary effects as spare parts production and transportation. As a result of these factors, the 'throw-away' philosophy was a very vulnerable luxury. During the last fifteen or so years, environmental factors with respect to mechanical system operation have changed 2 drastically. 792 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Starting with Volume 30, 1965, Structure Reports is produced in a new format by photo-offset printing from typed manuscript with unjustified lines. At the time when the decision for this change was taken, the cost of setting the manuscript in type was becoming so high as to render the cost of individual subscription pro hibitive. At that time automatie typing methods giving justified lines, etc. for photo-offset reproduction did not offer any saving over type setting, but hand typing of the manuscripts could give a considerable saving in production costs. In the belief that a publication that is too expensive to buy is of little value, the format has been changed sacrificing elegance to availability. The new format does not lead to increased length of the volumes since the information content of the typed and typeset pages is practically identical. How ever, the amount of work to be reported demands the eventual separation of Structure Reports into two volumes, A. Metals and Inorganic and B. Organic. It was convenient to introduce this change also at Volume 30, and with Volume 31 further to restriet the publication of crystal data, so that from 1966 onwards the reports deal almost entirely with complete structure determinations only. In the past the aim of Structure Reports has been to present critical reports on all work of crystallographic structural interest, whether it is derived directly from X-ray, electron or neutron diffraction, or even indirectly from other experiments. 496 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -Over the past twenty years, technical advances in coronary arteriography have contributed to our understanding of the pathophysiologic aspects and natural history of coronary artery disease. Probably more than 700. 000 coronary arterio grams are performed annually throughout the world. Usually, these arteriograms are interpreted visually to determine the morphologic extent and severity of coronary artery disease. These subjective determinations, which are hampered . by relatively large intra- and interobserver variations, are used as a basis for critically important therapeutic decisions: Which arteries are to be revascular ized, which lesions are suitable for coronary bypass surgery or for percutaneous coronary angioplasty To improve on this clinical decision making, on the treat ment and follow-up of such patients, new, objective and reproducible techniques for the assessment of the extent and severity of coronary artery disease, both in terms of anatomy and functional significance of the lesions, must be made widely available. With such new procedures and technologies the efficacy of new thera peutic procedures, the effects of vasodilating and constricting drugs, and the results of long-term studies on the regression and progression of atherosclerotic plaque can be determined in an objective and cost-effective manner. 288 pp. Englisch.
