Taschenbuch. Zustand: Neu. Neuware - The problem of unintended pregnancies among adolescents is a serious one. Millions of dollars have been spent and hundreds of social science investigations have been conducted in the attempt to address the problem. The present book reports the results of a federally funded research project on… parent-teenager communication about premarital sex and birth control. Both the role and potential of parents in influencing the sexual behavior of their teenagers has been questioned by many social scientists. The literature is characterized by studies that tend to observe little relationship between measures of parent-teen communication and teen sexual behavior. Many of our colleagues informally express the viewpoint that parents have little to do with the sexual behavior of their teens and that attempts to reduce unintended pregnancies through parental involvement will be futile. Indeed, when we first sought funding for the present research, several reviewers were skeptical for just this reason. It is our belief that parents can play an important role in preventing unintended pregnancies. In our opinion, past research has failed to make important conceptual distinctions which has resulted in an underestimation of the potential utility of parent-teen communication. We believe that the study reported here is consistent with this opinion. We have written the book with two goals. First, we wanted to identify important conceptual and methodological points that future researchers can consider in exploring this important area of inquiry. Second, we wanted to develop some of the applied implications of these points vis-a-vis our data.

Buch. Zustand: Neu. Neuware - One of the most intriguing questions in image processing is the problem of recovering the desired or perfect image from a degraded version. In many instances one has the feeling that the degradations in the image are such that relevant information is close to being recognizable, if only the image co…uld be sharpened just a little. This monograph discusses the two essential steps by which this can be achieved, namely the topics of image identification and restoration. More specifically the goal of image identifi cation is to estimate the properties of the imperfect imaging system (blur) from the observed degraded image, together with some (statistical) char acteristics of the noise and the original (uncorrupted) image. On the basis of these properties the image restoration process computes an estimate of the original image. Although there are many textbooks addressing the image identification and restoration problem in a general image processing setting, there are hardly any texts which give an indepth treatment of the state-of-the-art in this field. This monograph discusses iterative procedures for identifying and restoring images which have been degraded by a linear spatially invari ant blur and additive white observation noise. As opposed to non-iterative methods, iterative schemes are able to solve the image restoration problem when formulated as a constrained and spatially variant optimization prob In this way restoration results can be obtained which outperform the lem. results of conventional restoration filters.

Taschenbuch. Zustand: Neu. Neuware - Die psychosoziale Rehabilitation Krebskranker ist ein Thema von ständig wachsender Bedeutung. Die fachgerechte psychosoziale Nachsorge erfordert jedoch auch eine intensive systematische Rehabilitationsforschung. Deutsche und internationale Psychoonkologen und Rehabilitationsforscher stellen i…n diesem Buch aktuelle Entwicklungen auf diesem Gebiet vor. Das Themenspektrum umfaßt Forschungsstrategien, Krankheitsbewältigung, Lebensqualität, soziale Unterstützung, Bedarf an psychosozialer Hilfe sowie die Gestaltung von psychologischen Interventionen im Verlauf von Krebserkrankungen. Forschungsgruppen informieren über verschiedene, vom Bundesministerium für Forschung und Technologie geförderte Projekte mit den Schwerpunkten 'Krankheitsverarbeitung und -bewältigung', 'Belastung von in der Onkologie tätigen Berufsgruppen' und 'Versorgungsmodelle und Versorgungsstrukturen'. Die Darstellung der Forschungsansätze und -strukturen, der inhaltlichen Zielrichtung der Projekte, zeigt eindrucksvoll die Entwicklungsmöglichkeiten dieses Forschungsbereiches auf. Ärzten, Psychologen und Soziologen in Forschung und Praxis bietet das Buch einen aktuellen Überblick zum Stand der psychosozialen Forschung in der Rehabilitation Krebskranker.

Taschenbuch. Zustand: Neu. Neuware - Medizinisches Basiswissen und medizinische Fragestellungen kommen in der Psychotherapieausbildung häufig zu kurz, obwohl sie unerläßlich für die Kooperation zwischen Psychotherapeut und Facharzt anderer Disziplinen sind. In diesem Buch wird dem psychologisch geschulten Leser, der auch gelernt… hat, soziale Faktoren von Gesundheit und Krankheit zu erkennen und zuzuordnen, der biologisch-medizinische Teil der Krankheitslehre und Heilkunde nahegebracht. Die wichtigsten Störungen, Syndrome und Krankheiten werden leichtverständlich und übersichtlich anhand auffallender Leitsymptome dargestellt. Die medizinischen Termini sind auch in deutscher Sprache aufgeführt, das Sachverzeichnis - zugleich kurzgefaßtes Lexikon der im Buch vorkommenden Leitsymptome - ist als praxisnahe Überblicksinformation konzipiert. Dieses Buch vermittelt Psychologen und nichtärztlichen Psychotherapeuten die notwendigen Grundkenntnisse, um Differentialdiagnosen zu stellen und gibt Entscheidungshilfen bei der Frage, wann die Überweisung eines Patienten an einen Arzt nötig ist.
