Taschenbuch. Condizione: Neu. Neuware -Die Gestaltpsychologie wurde vor 100 Jahren entwickelt, um die akademische Psychologie für die Fragen der Praxis an die Wissenschaft vom Erleben und Verhalten öffnen: Wie kommt es, dass sich aus der Vielfalt von Eindrücken Erfahrungen bilden Wie kommen wir zu Problemlösungen Wie werden Spannungen abgebaut Was bestimmt unser Handeln Daraus wurde ein Konzept, das komplexe Wirkungszusammenhänge von einem einheitlichen Denksystem darstellen kann: der Analyse des im aktuellen psychischen Feld konkret Wirkenden und Sinnmachenden. Heute ist die Gestaltpsychologie präsent in der Psychotherapie, in der Wirtschafts- und Kulturpsychologie wie auch im interdisziplinären Diskurs des systemischen Denkens, der Organisationstheorie und der Wirtschaftsästhetik. Im Buch wird das Konzept in seiner historischen Entwicklung vorgestellt und mit den Fragen konfrontiert, denen sich eine praxistaugliche und 'praktische Theorie' stellen muss. 56 pp. Deutsch.

Taschenbuch. Condizione: Neu. Neuware -Sobald zwei Menschen im Handeln, Denken und Fühlen miteinander interagieren, ist Konfliktpotenzial vorhanden. Es gibt die unterschiedlichsten Konfliktarten und die Zahl der möglichen Konfliktauslöser ist groß. Dies bedeutet jedoch nicht, dass ein Konflikt entstehen muss. Je nach Persönlichkeitsstruktur, Rahmenbedingungen und Art der Kommunikation kann eine Konfliktauslösung durchaus vermieden werden. Da die Kommunikation heutzutage stark technisch geprägt ist, erhöht sich die Konfliktwahrscheinlichkeit aufgrund von eingeschränkter Wahrnehmung und etwaiger Fehlinterpretationen. Der Autor Norbert J. Heigl zeigt auf, was man selbst tun kann, um Konflikte entweder nicht entstehen zu lassen oder sich konstruktiv damit zu beschäftigen, ohne sich unterordnen zu müssen. Konflikte bieten eine oft unerkannte Möglichkeit, Beziehungen zu Menschen zu stärken und emotional zu vertiefen. So werden Lösungsstrategien dargestellt, die unabhängig von der Konfliktart angewandt und zur Stärkung des eigenenSelbstwertgefühls genutzt werden können. 33 pp. Deutsch.

Taschenbuch. Condizione: Neu. Neuware -Corruption is usually understood as hampering political development, economic growth and democratic participation of citizens, but comparing the effects of corruption for different political regimes presents astonishingly complex findings. The ongoing persistence of corruption underlines that it is not only dysfunctional, but can be highly functional as well. This special issue brings together contributions from comparative politics, political science and economics which precisely focus on these (dys) functionalities of corruption in political regimes across various world regions. The question of methodological pluralism is especially important for studying corruption comparatively. While on an international level a trend towards an increased use of quantitative methods in political science as well as in economics can be observed, the special issue underlines the importance of having a pluralistic approach for grasping the complex and multi-layered effects of the phenomenon. Of similar importance is the adoption of a comparative perspective that includes different world regions in order to understand the different roles of corruption in developing, transforming and developed countries alike.Dr. Tobias Debiel is Director of the Centre for Global Cooperation Research and of the Institute for Development and Peace (INEF). Since 2006, he is also Professor in International Relations and Development Policy, Institute of Political Science, University of Duisburg-Essen.Dr. Andrea Gawrich is Professor for International Integration at the University of Gießen.

Taschenbuch. Condizione: Neu. Neuware -The expression 'Near-Death Experience' is associated in the popular understanding with access to knowledge about our transition between the states of life and death. But how should such experiences be interpreted Are they verifiable with scientific methods If so, how can they be explained Attempting to relate matters of scientific knowledge to subjective experience and the realm of belief is a difficult balancing act and has led to a variety of approaches to the topic. This work scrutinizes the diverse views and also myths, about near-death experiences and describes them from a scientific standpoint. Situated at the intersection of neuroscience, psychology, philosophy and religious studies this book will appeal to a broad audience of both scientists and general readers.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 156 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -Recently, mobile security has garnered considerable interest in both the research community and industry due to the popularity of smartphones. The current smartphone platforms are open systems that allow application development, also for malicious parties. To protect the mobile device, its user, and other mobile ecosystem stakeholders such as network operators, application execution is controlled by a platform security architecture. This book explores how such mobile platform security architectures work. We present a generic model for mobile platform security architectures: the model illustrates commonly used security mechanisms and techniques in mobile devices and allows a systematic comparison of different platforms. We analyze several mobile platforms using the model. In addition, this book explains hardware-security mechanisms typically present in a mobile device. We also discuss enterprise security extensions for mobile platforms and survey recent research in the area of mobile platform security. The objective of this book is to provide a comprehensive overview of the current status of mobile platform security for students, researchers, and practitioners.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 112 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -Performing fieldwork in healthcare settings is significantly different from fieldwork in other domains and it presents unique challenges to researchers. Whilst results are reported in research papers, the details of how to actually perform these fieldwork studies are not. This is the first of two volumes designed as a collective graduate guidebook for conducting fieldwork in healthcare. This volume brings together the experiences of established researchers who do fieldwork in clinical and non-clinical settings, focusing on how people interact with healthcare technology, in the form of case studies. These case studies are all personal, reflective accounts of challenges faced and lessons learned, which future researchers might also learn from. We open with an account of studies in the Operating Room, focusing on the role of the researcher, and how participants engage and resist engaging with the research process. Subsequent case studies address themes in a variety of hospital settings, which highlight the variability that is experienced across study settings and the importance of context in shaping what is possible when conducting research in hospitals. Recognising and dealing with emotions, strategies for gaining access, and data gathering are themes that pervade the studies. Later case studies introduce research involving collaborative design and intervention studies, which seek to have an immediate impact on practice. Mental health is a theme of two intervention studies as we move out of the hospital to engage with vulnerable participants suffering from long-term conditions and people in the home. This volume closes with an intervention study in the developing world that ends with some tips for conducting studies in healthcare. Such tips are synthesised through the thematic chapters presented in the companion volume.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 132 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -For over 30 years, the stepped care approach has been used in the management and treatment of hypertension. This approach advocates the use of initial monotherapy to reach the desired blood pressure, and the subsequent use of additional drugs with complementary modes of action, until the target BP is achieved. However, current control rates for hypertension suggest that such an approach may be outdated and no longer effective in the management of hypertension. Clinical trials have shown that more than 50% of patients require a combination of drug therapies to achieve their target BP. Some proponents of combination therapy have argued that the risk of adverse side effects and non-compliance will be lower than that compared to monotherapy, which initially requires higher doses to be administered to be effective. Consequently, there have been increasing calls of the necessity for a much more combined approach in the treatment of hypertension. Adding to this, Combination Therapy in Hypertension will cover current control rates of blood pressure worldwide, the benefits of monotherapy and combination therapy, examine the effectiveness, risk of adverse effects, compliance, and cost of the available therapies and will also include information on relevant outcome studies.Springer-Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 92 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -This volume presents recent developments in the area of Lévy-type processes and more general stochastic processes that behave locally like a Lévy process. Although written in a survey style, quite a few results are extensions of known theorems, and others are completely new. The focus is on the symbol of a Lévy-type process: a non-random function which is a counterpart of the characteristic exponent of a Lévy process. The class of stochastic processes which can be associated with a symbol is characterized, various schemes constructing a stochastic process from a given symbol are discussed, and it is shown how one can use the symbol in order to describe the sample path properties of the underlying process. Lastly, the symbol is used to approximate and simulate Levy-type processes.This is the third volume in a subseries of the Lecture Notes in Mathematics called Lévy Matters. Each volume describes a number of important topics in the theory or applications of Lévy processes and pays tribute to the state of the art of this rapidly evolving subject with special emphasis on the non-Brownian world.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 220 pp. Englisch.

Buch. Condizione: Neu. Neuware -Current technological, demographic and globalization trends are not only leading to intensified competition; they also indicate that new business models are rapidly emerging but only to disappear again just as quickly. Timely recognition of the new changes, jettisoning of old approaches and rapid implementation of the currently required changes within a company are now decisive competitive factors. Those who best survive (and thrive) in the future will be those who dramatically increase their success rate within this change process. Building on his best-selling book 'The Strategy Scout' Matthias Kolbusa explains the decisive principles in this rapidly changing business environment.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 200 pp. Englisch.

Buch. Condizione: Neu. Neuware -Social media such as instant messaging (IM), social networking sites (SNS), blogs and microblogs are an integral part of adolescents¿ lives in China. Anecdotal evidence reported in the news has suggested that the increasing popularity of social media could make adolescents more vulnerable to being addicted. This exploratory study proposes the concept of ¿social media addiction¿ and examines (a) whether social media addiction exists among adolescents in urban China and, if so, who the addicts are, what their symptoms are and to what extent they are addicted; (b) whether sociopsychological traits (e.g., need for affiliation, impression management, narcissism and leisure boredom) can predict social media addiction among adolescents; (c) what gratifications are obtained by adolescents from their use of social media and whether these gratifications can predict social media addiction and (d) to what degree social media addiction influences adolescents¿ academic performance and social capital.This study employed quantitative questionnaire surveys among adolescents as the main research method, supplemented by qualitative pre-survey focus groups among adolescents and post-survey in-depth interviews among parents and teachers. Questionnaire surveys were conducted based on a multi-stage cluster sampling of seven middle schools in five urban Chinese cities: Beijing, Shanghai, Guangzhou, Shenzhen and Xiamen. The final sample consisted of 1,549 adolescents, of whom 90% had used social media. Using Young¿s classic definition of Internet addiction, 15.6% of participants were classified as social media addicts. The addicted adolescents were often self-absorbed, bored with their leisure time, and good at using manipulation through social media for impression management. Addicts experienced four major social media addiction symptoms: preoccupation, adverse consequences, alleviation of negative emotions and loss of interest in social activities.The seven social media gratifications identified in this study can be categorized into social, information and entertainment gratifications. Among these, entertainment gratifications had the most power to predict social media addiction, while information gratifications were the least likely to lead to addiction. Furthermore, these gratifications were found to be powerful mediators between the adolescents¿ sociopsychological traits and social media addiction. Finally, the results also indicated that social media addiction and its symptoms had a significant negative impact on adolescents¿ academic performance and social capital.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 164 pp. Englisch.

Buch. Condizione: Neu. Neuware -Locally computable (NC0) functions are 'simple' functions for which every bit of the output can be computed by reading a small number of bits of their input. The study of locally computable cryptography attempts to construct cryptographic functions that achieve this strong notion of simplicity and simultaneously provide a high level of security. Such constructions are highly parallelizable and they can be realized by Boolean circuits of constant depth.This book establishes, for the first time, the possibility of local implementations for many basic cryptographic primitives such as one-way functions, pseudorandom generators, encryption schemes and digital signatures. It also extends these results to other stronger notions of locality, and addresses a wide variety of fundamental questions about local cryptography. The author's related thesis was honorably mentioned (runner-up) for the ACM Dissertation Award in 2007, and this book includes some expanded sections and proofs, and notes on recent developments.The book assumes only a minimal background in computational complexity and cryptography and is therefore suitable for graduate students or researchers in related areas who are interested in parallel cryptography. It also introduces general techniques and tools which are likely to interest experts in the area.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 212 pp. Englisch.

Buch. Condizione: Neu. Neuware -In this thesis, quantum estimation theory is applied to investigate uncertainty relations between error and disturbance in quantum measurement. The author argues that the best solution for clarifying the attainable bound of the error and disturbance is to invoke the estimation process from the measurement outcomes such as signals from a photodetector in a quantum optical system. The error and disturbance in terms of the Fisher information content have been successfully formulated and provide the upper bound of the accuracy of the estimation. Moreover, the attainable bound of the error and disturbance in quantum measurement has been derived.The obtained bound is determined for the first time by the quantum fluctuations and correlation functions of the observables, which characterize the non-classical fluctuation of the observables. The result provides the upper bound of our knowledge obtained by quantum measurements.The method developed in this thesis will be applied to a broad class of problems related to quantum measurement to build a next-generation clock standard and to successfully detect gravitational waves.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 136 pp. Englisch.
