Add to basketTaschenbuch. Condition: Neu. Neuware -Inhelder in her introduction. The reason for this unity is that explanatory adequacy can be attained only by exploring the formative and constructive aspects of development. To explain a psychologic reaction or a cognitive mechanism (at all levels, including that of scientific thought) is not simply to describe them, but to comprehend the processes by which they were formed; failing that, one can but note results without grasping their meaning. JEAN PlACET VI Man distinguishes himself from other creatures primarily by his abstract reasoning capacity and his ability to communicate his knowledge by highly complex symbolic processes. What is called 'humanity' and progress is to a large degree a measure of his consciousness and the deployment of his creative potentials. There are few scientists who have explored the universe of cogni tion, and contributed to the understanding of the realm of knowledge, with greater genius, care, and scientific intuition than Jean Piaget and his longtime collaborator Barbel Inhelder. Professor Inhelder and her assistant Dr. Harold Chipman realized this book in spite of the heavy load of research, teaching, and administra tive duties in a rapidly expanding Institute. It is therefore a particular pleasure for me to presen t this book.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 320 pp. Englisch.

Neuware -On March 8/9, 1976 a workshop on 'Mathematical Models in Medicine' was held at Mainz (German Federal Republic) by the group of 'Mathe matical Models' of the Deutsche Gesellschaft fUr Medizinische Doku mentation, Informatik und Statistik. Purpose of this conference was to bring together experts from the GFR and neighbouring countries working in this field to evaluate possibilities and limits of this area of research in discussions with interested participants. This issue of Lecture Notes contains the invited contributions as well as the relevan~ remarks made by the discussants. Corresponding to the aims of the workshop the contributors had been encouraged to demon strate their mathematical models in the light of actual applied examples. It had been our intention to restrict attention to a small number of specific areas in order to achieve a concentrated in depth treatment in these restricted areas. The areas chosen contain two - Epidemio logy and Cell Models - which in the organisers feeling are not yet as well established in Continental Europe and one - Pharmacokinetic- with a more direct appeal to applied workers. While in the Epidemio logy of infectious and parasitic diseases today strategies of control and eradication are gaining importance, the cell models are concerned with explaining the modes of genesis of cancerous growth and the kinetics and interactions within multi-cell structures.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 296 pp. Englisch.

Es befaBt sich ausschlieBlich mit dem Lernen im schulischen und akademischen Bereich, d. h. es bleibt beschrankt auf das verbale Lernen. Beim verbalen Lernen unterscheiden wir das sog. Auswendiglernen und das 'Einsichtslernen', auch einsichtsvolles Lernen, von manchen auch 'Problemlosungslernen' genannt. Urn von vorneherein MiBverstandnisse zu vermeiden, muB hier festgestellt werden, daB man nicht von 'der' Lernmethode oder 'einer' Lernmethode schlechthin sprechen kann, die fUr aIle Studenten geeignet ware. Es geht in diesem Buch vielmehr urn Lernstrategien, die darlegen, wie Lernmaterial bewaltigt und die entsprechenden Lernvorgange durchgefUhrt werden konnen. Oft wird der Leser viele seiner eigenen Lern strategien bestatigt und formal dargestellt finden, die er bereits kennt und benutzt; jedoch werden - so hoff en wir - auch neue Lernmethoden vorgestellt, die dem Lernenden viel Zeit und Miihe ersparen. Hier beschreiben wir nur Lernmethoden und Lernstrategien, die aus der experimentellen Lern forschung abgeleitet sind; rein spekulative Aussagen sind als solche besonders gekenn zeichnet. Da das Buch nicht auf irgendeine Fachrichtung zugeschnitten ist und auBerdem die Beispiele allgemein gewahlt sind, kann es fUr Studenten VII aller Fachrichtungen von Nutzen sein. Daruber hinaus konnen aber auch alle diejenigen davon profitieren, fUr die mehr oder weniger der formale Lernvorgang von Bedeutung ist, sei es nun in den Sekundarschulen, in Trainings programmen der Industrie oder beim Eigen studium. 104 pp. Deutsch.

This item is printed on demand - it takes 3-4 days longer - Neuware -This book contains the contributions and discussions of the second symposium on vascular smooth muscles held in Ttibingen in February, 1976. It provides an up-to-date review of the role of ions in the trans mission of signals from the perivascular space to the contractile ele ments of the smooth muscle cells. The various aspects are mainly discussed from a functional point of view and only few contributions concern the morphologic variations of cells .during varying ion activity. Special emphasis was placed on the significance of ion variations in the cerebral tissue and their rela tion to metabolic and nervous control of the brain vessels. It could be seen in this symposium that new techniques enabled the in vestigators to make considerable progress in the understanding of the actions and the interactions of ions on the membranes and on the inter nal structures of the smooth muscle cells if one compares the findings with the results of the previous symposium held in Ttibingen in 1972. It became evident that the insight into ionic actions enables the de velopment of powerful tools to be utilized in future therapy of dis turbances of local blood flow regulation. The participants of the symposium render thanks to the Dr. Thiemann GmbH in Ltinen, which supported the symposium and this publication in a generous way. Finally it is a pleasure of the Editor to thank the members of the Physiological Institute of Ttibingen for their encouragement in the ar rangement of the meeting. 180 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -The increasing frequency of coronary diseases, the still insufficient results of prevention have brought physicians to try to reduce as much as possible the con sequences of ischaemic heart disease. Coronary units and new treatments have some what reduced the dramatic complications of the acute phase; but after the latter, evil effects of the disease remain at the physiological, psychological and social level. It is the aim of rehabi~itation to analyze these problems, to reduce them or to solve them whenever possible. When this conception of 'complete coronary care' took the lead, the necon ditioning effects of heart disease and of immobilization on physical conditi ons were emphasized: physical training programmes were prepared and their main lines and physiological effects are now fairly well known. But it was soon obvious that the psychological problems raised by the patient and his environment 'are equally important. Their approach is however much more difficult and their treatment particularly complex. So, the Council on Rehabilitation of the International Society of Cardiology is really grateful to Professor Dr. HALHUBER and Dr. Dr. STOCKSMEIER for giving the opportunity to specialists to discuss together this particular aspect of coronary disease. The discussions have been devoted to the methods of approaching the patient as well as to the therapeutic aspects and the role of psychologists in the rehabilitation programmes: some papers have been devoted also to the possible role of the personality as a risk factor in the development of the disease. 196 pp. Englisch.
