Taschenbuch. Condición: Neu. Neuware -EXCEPT for chapter 8, an editorial foot-bridge across the con fused years which separate the Dutch Republic from the King dom of the Netherlands, the essays collected in this volume were originally read and discussed at meetings of Dutch and British historians held between 22 and 27 September 1969 in a number of delightful comers of Groningen and Friesland. That this con ference took place at all was due in the first instance to the initiative and organizing genius of the Instituut voor Geschiedenis of the University of Groningen: particular thanks are due to the Rector Magnificus and his colleagues of that illustrious place of learning. On behalf of those fortunate enough to take part, we also wish to place on record our deep gratitude for the benevolent assistance of the Netherlands Ministerie van Onderwijs, of the H. S. Kammingafonds and of the Groninger Universiteitsfonds.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This birefs examines mortality among young children in the period from the seventeenth to the nineteenth century. It does so using several types and sources of information from the census unit England and Wales, and from Ireland. The sources of information used in this study include memoirs, diaries, poems, church records and numerical accounts. They offer descriptions of the quality of life and child mortality over the three centuries under study. Additional sources for the nineteenth century are two census-derived numerical indexes of the quality of life. They are the VICQUAL index for England and Wales, and the QUALEIRE index for Ireland. Statistical procedures have been applied to the numbers provided by the sources with the aim to identify effects of and associations between such variables as gender, age, and social background. The briefs examines the results to consider the impact of children's deaths upon parents and families, and concludes that there are differences and continuities across the centuries. 100 pp. Englisch.…

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book was originally published as a doctoral thesis and was de fended by the author at the Tilburg School of Economics in 1969. It has the characteristics of a work on industrial econometrics. On the one hand relevant economical, statistical and mathematical theory is treated and on the other a model for a very actual situation has been created and utilised to solve a practical problem. The selection from current reference material always has a personal tinge of course, and other theoreticians will find some of the author's departures from the theme a little unnecessary. However, if the theory propounded in this book is tested for its relevance in solving practical problems, the selection may be regarded as a success. Thanks to the way in which the case is developed the book is of great practical use. So often in writings on operations research theory is applied to so-called practical examples, which in fact can only be des cribed as five finger exercises. It is clear from the early chapters that the author has struggled with this problem but that he has found a solution. And in his concluding remarks he indicates briefly how this case can be incbrporated in a context which goes beyond short-term optimisation. In the description of the preparatory and implementation phases the author shows how a clash between practical implementation and theoretical application can successfully be avoided in this preparatory work. 196 pp. Englisch.…

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -During the last decade, the econometric study of investment behaviour has developed from the descriptive construction of empirical investment equations, as first performed by J. Tinbergen in his well-known 19- publication: 'A Method and its Application to Investment Activity', to the empirical testing of increasingly explicit theories of production behaviour. It was principally D. Jorgenson who gave a great push to this intensified interest in micro-economic investment, with his famous 1965-paper: 'Anticipation and Investment Behaviour', in which he formulated a pure neoclassical model of investment behaviour under the conditions of a (simple) homogeneous production technology and perfectly competi tive markets. But, although the scope of the familiar flexible accelerator model was considerably extended by the introduction of relative factor prices, the resulting investment relationship generally remained one of the most ill-estimated equations in econometric models. The very rigid assumptions of pure neoclassical models might have caused these bad results. More over, the required ex post measure for aggregate capital stock is very deficient for most economies. Hence, it should be interesting to formulate investment models subject to less rigid restrictions on production and market behaviour and, preferably, not containing any measure of aggre gate capital stock. 356 pp. Englisch.…

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Every day people frequently have to make a choice. For practical and scientific reasons therefore it is interesting to know what choices they make and how they arrive at them. An approach to this question can be made via psychology. However, it is also possible to approach it on a more formal basis. In this book Dr. Wedde pohl describes the logical structure of an individual's rational choice. It is this formal, logical approach to the decision problem that makes the book interesting reading matter for all those who are engaged in the study of individual choice. The introduction apart this study may be divided into two parts. The first part, consisting of chapters II and III, deals with choice theory on a very abstract level. In chapter II some mathematical concepts are presented and in chapter III two related choice models are treated, the first one based on preferences, the second one on choice functions. The second part consists of chapters IV, V and VI and covers consumer choice theory. After the pre sentation of the mathematical tools, two models that are extensions of the models of chapter III are dealt with. In the discussion of consumer choice theory the concept of duality plays an important role and it is found that duality is closely related to the notion of favourability introduced in chap ter II I. Mr. Weddepohl's study forms an introduction to a larger research project to develop the theory of collective choice. 184 pp. Englisch.…

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The introduction of public goods into economic theory has recently received substantial attention from economists. Both the increasing significance of public goods and the deficiencies of the private goods-oriented allocation mechanisms call for a re orientation of the classical general equilibrium models such as the one designed by Walras exactly a century ago. Although several approaches to this problem are possible, the duality approach seems to be very fruitful. In this study, Dr. Ruys applies and develops the mathematical theory of polarity to gain a deeper insight into the economic theory of value. He not only uses the duality approach to simplify formal proofs related to public goods, but he also gives an interpretation to the application of polarity operations which goes far, beyond its formal significance. This study is in a way closely related to the publication 'Axiomatic choice models' by Dr. H. N. Weddepohl, which is volume 3 of the Tilburg Studies on Economics. 252 pp. Englisch.…

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -I constructed four miniature houses of worship-a Mohammedan mosque, a Hindu temple, a Jewish synagogue, a Christian cathedral-and placed them in a row. I then marked 15 ants with red paint and turned them loose. They made several trips to and fro, glancing in at the places of worship, but not entering. I then turned loose 15 more painted blue; they acted just as the red ones had done. I now gilded 15 and turned them loose. No change in the result; the 45 traveled back and forth in a hurry persistently and continuously visiting each fane, but never entering. This satisfied me that these ants were without religious prejudices-just what I wished; for under no other conditions would my next and greater experiment be valuable. I now placed a small square of white paper within the door of each fane; and upon the mosque paper I put a pinch of putty, upon the temple paper a dab of tar, upon the synagogue paper a trifle of turpentine, and upon the cathedral paper a small cube of sugar. First I liberated the red ants. They examined and rejected the putty, the tar and the turpentine, and then took to the sugar with zeal and apparent sincere conviction. I next liberated the blue ants, and they did exactly as the red ones had done. The gilded ants followed. The preceding results were precisely repeated. 388 pp. Englisch.…

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -IRVING LEVESON The 19608 was a period of rapid social and economic change, coupled with spectacular growth in the role of government in dealing with social issues. The demands of public programs and policies created enormous pressures for improved information and analyses. In the field of drug abuse these pressures were compounded by the rapid rise of drug use and the absence of much critical information and analysis. The most elementary steps to develop a data base were just beginning, and many years of effort would be required before the accumulation of knowledge could produce. a strong foundation for public policy. There has been enormous progress in improving knowledge about drug abuse since the mid-1960s. However, as in many fields, research has concentrated on a few questions while others largely are ignored, and even where studies exist there are problems of assimilation. Information is widely dispersed, not always accessible and often not in the most useful form. Many analysts do not have adequate understanding of the ways in which studies might enter into policy development, while at the same time, persons responsible for policy formation often do not have sufficient knowledge of how to use research to help resolve policy issues. A major objective of this volume is to illustrate the formation of linkages which may bridge the gap between research and policy. 216 pp. Englisch.…

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -In 1963 the director general of the 'Office de la Recherche Scientifique et Technique Outre-Mer' (ORSTOM) asked me to form a well structured team of hydrobiologists based at Fort-Lamy (now N'Djamena) where a laboratory could be built as a branch of the already existing ORSTOM Center. The International Biological Program, IBP, had at this time recommended an integrated study of ecosystems selected in proportion to their representation of a particular zone or ecological conditions. I took this opportunity to propose Lake Chad as the model of a tropicallake in a semi-arid c1imate as part of the activity of the section Productivity of freshwater communities (PF). With the efficient help ofDr B. Dussart a research program was established involving the establishment of a permanent team of ten researchers in Chad. Apart from myself, ORSTOM only had three hydrobiologists: Mr R. Gras, Mr G. Loubens and Mr A. Iltis. These valuable researchers who had been working for the 'Centre Technique et Forestier Tropical' and had acquired considerable experience in African freshwaters, unhesitatingly accepted to join me at Fort-Lamy. It was necessary to enlarge this team with so me young and enthusiastic collaborators, namely, Mr C. Leveque, Mr C. Dejoux, Miss S. Duwat, Mr L. Lauzanne and Mr. J. R. Durand, later joined by Mr J. P. Carmouze and Mr J. Lemoalle. 592 pp. Englisch. …

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The concept that hormones influence tumor growth originated in 1889 with the proposal of Albert Schinzinger who suggested that breast cancer is related to the ovaries. Several years later, Sir George Beatson observed that remission of disseminated breast cancer could be achieved in premenopausal patients by performing bilateral oophorectomy. As a result of the contri butions of Hedley Atkins, Charles Huggins and others, additive and ablative hormonal therapies have been widely used for the treatment of advanced breast cancers for several decades. Model systems to study the effects of hormones on growth and regression of breast tumors have been available for many years; however, the complexities of the hormonal environment have rendered in vivo studies difficult in man and experimental animals. Recently, the availability of long-term cultures of breast cancer cells has stimulated many investigators to use these cell lines to unravel the mechanisms of hormone action. Because of the extreme diversity and complexity of advances regarding the endocrinology of the breast and breast cancers, a multi-authored review was deemed necessary. It has been gratifying to receive contributions from many noted scholars. In Volume I of this monograph, the influence of steroid hormones and their antagonists upon normal and neoplastic tissues of the mammary gland are presented. In Volume II, the effects of peptide and other hormones are reviewed. 300 pp. Englisch.…

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Medical students are to a large extent taught by people who have undertaken little or no formal study in the field of education. Although formal study of any subject is no guarantee of satisfactory on-the-job performance, teaching practice itself without a knowledge of the fundamental princi ples of education is likely to bring distortions into the teaching situation. Our own experience leads us to believe that many teachers are concerned at this lack of expertise. This concern is manifest by their willing participation in activities which provide them with practical assistance in improving their educational skills. Unfortunately, few books have been written to aid the average clinical teacher wishing to gain a perspective on basic educational principles or seeking suggestions on how these might be applied to teaching. A previous publication by the Advisory Centre for University Education (ACUE) at the University of Adelaide, entitled University Teaching, has proved to be very popular, both locally and overseas, and has clearly met the needs of organi zers and participants in teacher training programmes in tertiary institutions. The success of this publication, and our experience with a variety of educational activities organized for staff of medical and dental schools and postgraduate organizations, led us to believe that a pragmatic educational guide for medical teachers would be of value to all such teachers and particularly to those asked to undertake an educational task for the first time. 164 pp. Englisch.…

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Architectural stress is the inability of a system design to respond to new market demands. It is an important yet often concealed issue in high tech systems. In From scientific instrument to industrial machine, we look at the phenomenon of architectural stress in embedded systems in the context of a transmission electron microscope system built by FEI Company. Traditionally, transmission electron microscopes are manually operated scientific instruments, but they also have enormous potential for use in industrial applications. However, this new market has quite different characteristics. There are strong demands for cost-effective analysis, accurate and precise measurements, and ease-of-use. These demands can be translated into new system qualities, e.g. reliability, predictability and high throughput, as well as new functions, e.g. automation of electron microscopic analyses, automated focusing and positioning functions.From scientific instrument to industrial machine takes a pragmatic approach to the problem of architectural stress. In particular, it describes the outcomes of the Condor project, a joint endeavour by a consortium of industrial and academic partners. In this collaboration an integrated approach was essential to successfully combine various scientific results and show the first steps towards a new direction. System modelling and prototyping were the key techniques to develop better understanding and innovative solutions to the problems associated with architectural stress.From scientific instruments to industrial machine is targeted mainly at industrial practitioners, in particular system architects and engineers working on high tech systems. It can therefore be read without particular knowledge of electron microscope systems or microscopic applications. The book forms a bridge between academic and applied science, and high tech industrial practice. By showing the approaches and solutions developed for the electron microscope, it is hoped that system designers will gain some insights in how to deal with architectural stress in similar challenges in the high tech industry. 124 pp. Englisch.…

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Vacuum apparatus is widely used in research and industrial establishments for providing and monitoring the working environments required for the operation of many kinds of scientific instruments and process plant. The vacuum conditions needed range from the relatively coarse vacuum requirements in applications covering diverse fields such as food packaging, dentistry (investment casting), vacuum forming, vacuum metallur gical processes, vacuum impregnation, molecular distillation, vacuum drying and freeze drying etc. to the other extreme involving the highest possible vacuum as in particle accelerators, space technology -both in simulation and outer space, and research studies of atomically clean surfaces and pure condensed metal films. Vacua commence with the rough vacuum region, i.e. from atmosphere to 100 Pa \* passing 6 through medium vacuum of 100 Pa to 0 1 Pa and high vacuum of 0 1 Pa to 1 J.lPa (10- Pa) until ultra high vacuum is reached below 1 J.lPa to the limit of measurable pressure about 12 I pPa (10- Pa). 452 pp. Englisch.…

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book is about music. the instruments and players who produce it. and the technologies that support it. Although much modern music is produced by electronic means. its underlying basis is still traditional acoustical sound production. and that broad topic provides the basis for this book. There are many fine books available that treat musical acoustics largely from the physical point of view. The approach taken here is to present only the fundamentals of musical physics. while giving special emphasis to the relation between instrument and player and stressing the characteristics of instruments that are of special concern to engineers and technicians in volved in the fields of recording. sound reinforcement. and broadcasting. In order to understand musical instruments in their normal performance environments. the student must have a basic working knowledge of physical and architectural acoustics. The book begins with a review of the elements of acoustics. stressing the nature of sound fields and phenomena that are wavelength-dependent. The book then moves on to a discussion of those aspects of psychological acoustics that are of special concern to music technicians. most notably concepts of stereophonic imaging. loudness-related phenomena. and critical band theory. 304 pp. Englisch.…

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The technical importance of flexible composite structures needs no emphasis nor has there been any lack of material descriptive of their manufacture or properties. The starting points of such descriptions have invariably been from the viewpoint of the rubber industry and the presence of a suitable textile has been taken for granted, its strength properties indicated and the technological content confined to the manufacturing process within the rubber industry. An attempt is made here to work from the textile outwards. Industrial fabrics are far heavier than garment textiles, are not produced in the same bulk quantities and need to be specially constructed to provide the balance of properties which will combine with those of the rubber to give the final. product. The most important composite structure formed from textiles and rubber is, of course, the pneumatic tyre. It may therefore seem strange that no chapter deals with this. The reason is quite simple. To deal with the structure and design of the pneumatic tyre in a similar depth of detail as is done here for conveyor or power transmission belting, or hose, would require disproportionate space; in fact, a second volume equal in size to the present one. This book discusses from the textile viewpoint the various reinforced rubber structures used industrially with the exception of the tyre. These other uses of industrial fabrics can be discussed in adequate detail and cover the whole range of the technology involved in the space available in the one volume. 288 pp. Englisch.…

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book provides instruction in applying basic treatment strategies to patient care. Emphasis is placed on teachi. ng diagnostic skills, and especially, the therapeutic management of emotionally disturbed patients. This book is intended as a companion text to Basic Psychopathology: A Programmed Text, whi. ch focuses more on teaching the description and observational skills for diagnosing common psychopathologic syn dromes. Basic Psychotherapeutics gives pragmatic suggestions for treating a variety of psychopathologic disorders, many of which are newly classi fied in the Diagnostic Statistical Manual - III (DSM-II1) published by The American Psychiatric Association. We have adopted the terminology and many, but not all, of the diagnosti. c criteria used in DSM-III. The treatment recommendations proposed are eclectic in nature and the infor mation presented is non-theoretical and patient centered. Basic Psychotherapeutics is divided into three parts. The first re views basic data collection procedures and treatment skills; it includes chapters on interviewing, the mental status examination and pharmaco logic, psychologic and behavioral therapy. The next section includes chapters on commonly encountered psychiatric syndromes such as schiz ophrenic, affective and anxiety disorders. The final chapters are pre sentations of special clinical interest, such as the management of suicidal patients, psychiatric emergencies, treating the dying patient and his family, and others. 608 pp. Englisch.…

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The use of gamma-emitting radionuclides for diagnostic imaging in nuclear medicine has been established for many years. Sophisticated gamma ray detecting camera systems and computer links enable the clinical investigator to image different regions of the body and to quantify organ function. Parallel developments have also occurred in the field of radiopharmaceuticals, and today a wide range of products is available that will exhibit specific uptake within target tissues following parenteral administration. For example, radioiodide is taken up by the thyroid and iodinated fatty acids can be used to image the myocardium. Labelled antibodies have been used with success to target certain tumours. The concept of targeting has also been considered by pharmaceutical scientists who wish to deliver drugs rather than radionuclides to specific sites in the body. The systems that have been employed are often physically similar to those used as radiopharmaceuticals (for example colloids, aerosols and liposomes). Furthermore, pioneering work by Digenis and others in the United States States and by Alpsten and co-workers (1976)in Sweden had demonstrated the potential of gamma scintigraphy for investigating the fate of tablets and capsules in the gastrointestinal tract of man in a non invasive way. In 1979, the Biopharmaceutics Research Group at Nottingham together with academic pharmacists from Manchester held a one-day syffiposium at Nottingham University to discuss how radio nuclides could be used in drug formulation studies to provide better approaches for the delivery of drugs to their sitesof action. 352 pp. Englisch.…

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The last two decades have seen rapid advances in the technology used to produce pot plants. Glasshouses designed and orientated to give maximum light transmission, fully automatic heating and ventilating systems, carbon dioxide enrichment of the atmosphere, controlled photoperiods using automatic blackouts and incandescent lamps which enable plants such as chrysanthemum to be flowered at any time of the year, mist propagation techniques, chemical growth regulators which control the height of plants, automatic watering and feeding systems, etc.: these are only some of the developments which have transformed pot plant culture. There have also been many changes in the composts and systems used to grow the plants. Mineral soils, which formed the basis of the John Innes Composts, are now either too expensive or too difficult to obtain in suitable quality and sufficient quantity. Consequently the grower has been forced to seek other materials such as peat, perlite, vermiculite, plastic foam, shredded bark, etc. New types of fertilisers, new methods of heat sterilisation and new chemical sterilising agents are also being used. 280 pp. Englisch.…

This item is printed on demand - it takes 3-4 days longer - Neuware -Collection, like transport and storage, is one of the basic technical and economic components of the processes of converting Biomass into energy. In recent years much progress has been made in R&D and industrial appli cations for the collection of all types of Biomass resources/feedstock, which ranges from orchard prunings to tree-felling waste, from straw to seaweed, from specific energy crops to arable-farming residues of any kind. Though interesting results have certainly been achieved, many problems still remain, and their solution will largely influence the final use of these Biomass sources and residues. There are the problems of bringing out timber waste from inaccessible oak forests, and making the collection of algae and aquatic plants financially worthwhile j should ma chines be specially designed for this work j and what about the economic and social costs for a proper forest management policy such as forest fires, soil degradation and so on. The need to assess what positives advances have already been made in the Community's member countries, so that Community action in this sector can be directed most efficiently, prompted the Directorate-General for Energy of the Commission of the European Communities to organize this workshop in collaboration with the other departments active in this field. 340 pp. Englisch.…

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -It goes without saying that atomic structure, including its dual wave-particle nature, cannot be demonstrated in the classroom. Thus, for most science teachers, especially those in physics and chemistry, the textbook is their key resource and their students' core source of information. Science education historiography recognizes the role played by the history and philosophy of science in developing the content of our textbooks, and with this in mind, the authors analyze more than 120 general chemistry textbooks published in the USA, based on criteria derived from a historical reconstruction of wave-particle duality. They come to some revealing conclusions, including the fact that very few textbooks discussed issues such as the suggestion, by both Einstein and de Broglie, and before conclusive experimental evidence was available, that wave-particle duality existed. Other large-scale omissions included de Broglie's prescription for observing this duality, and the importance of the Davisson-Germer experiments, as well as the struggle to interpret the experimental data they were collecting. Also untouched was the background to the role played by Schrödinger in developing de Broglie's ideas. The authors argue that rectifying these deficiencies will arouse students' curiosity by giving them the opportunity to engage creatively with the content of science curricula. They also assert that it isn't just the experimental data in science that matters, but the theoretical insights and unwonted inspirations, too. In addition, the controversies and discrepancies in the theoretical and experimental record are key drivers in understanding the development of science as we know it today. 56 pp. Englisch.…
