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 -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.

Taschenbuch. Condizione: Neu. Neuware -This Brief explores emerging trends in drug use and distribution.This timely Brief examines recentexamples of emerging drugsincluding salvia (from the plantSalvia divinorum), bath salts (and other synthetic stimulants) and so-called research chemicals (primarily substituted phenethylamines, synthetic cousins of ecstasy), which havetended to receive brief levels of high intensity media coverage that may or may not reflect an actual increase in their usage.Over the pastdecade in particular,¿new¿ substances being used recreationally seem to come out of obscurity and gain rapid popularity, particularly spurred on by discussion and distribution over the internet. While changing trends in the drug market have always presented a challenge for law enforcement and public health officials, online forums, media coverage and other recent trends discussed in this Brief allow them to gain popularity more quickly and change more frequently. These rapid shifts allow less time for researchers to understand the potential health consequences of these substances and for law enforcement to stay abreast of abusesof legal substances. This work includes: 1) review of relevant research and literature, 2) review the Internet sources in which many deem important in influencing the emerging drug market, 3) discussion of national and international trends in use, abuse and distribution of these substances and4) examination of current drug policy and recommendations for the future. This brief will be useful for criminology and criminal justice, sociology and public health.It will also be useful for those that deal with youth and the problems that may develop during adolescence and early adulthood.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 108 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -The migration process is interpreted in a different way when researchers live in so-called societies of origin, than when it is interpreted from societies of destination¿even when research work is multi-situated. The localization of researchers in this field involves numerous factors that influence the modalities for conducting research. Research agendas are clearly mediated by these localizations and this book on the contemporary social sciences points out those mediations, breaking with the dichotomous readings that are implicit in this migration process (origin-destination, north-south, and cause-effect, to mention just a few). In the individual chapters, priority is given to presenting the modalities through which research is conducted in multidisciplinary or interdisciplinary teams on the American Continent. In summary, the focus of this book is on the narrative of methodological experience of the Practice of Research on Migration and Mobilities.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 200 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -On the occasion of the 95th birthday of Helmut Schmidt, West German Chancellor 1974¿1982, his biographer Hartmut Soell, Professor of History at Heidelberg University and former member of the German Parliament (1980¿1994), presents H. Schmidt as a Pioneer of International Economic and Financial Cooperation. Influenced by the catastrophes of the early 20th century (global economic crisis, dictatorship and war), Schmidt entered politics as a trained economist and was one of the most innovative policymakers from the 1960s to the 1980s. As minister of defense, economy and finance and as Chancellor he was able to implement many of his ideas for closer cooperation between Western industrial states on currency issues and energy policy during the 1970s. Together with French President Valéry Giscard d¿Estaing he launched the G7 summits in 1975 and his proposals for a European currency system (1978¿79) paved the way for the European economic and currency union. As editor of Die Zeit, he would later become an influential commentator.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 192 pp. Englisch.

Buch. Condizione: Neu. Neuware -Over the past years, we have heard and read plenty about how executives should behave more responsibly in the light of corporate governance. Despite all these efforts, many implementations of corporate governance provide no protection from potentially catastrophic ethical failures. This book emphasizes the introduction of a new corporate governance blueprint for addressing these concerns in a more authentic, organic and holistic way. It is a roadmap toward a high-performance ethical culture. By way of this innovative system, Dr. Hubert Rampersad and Saleh Hussain, MBA, are launching a revolutionary concept that actively has human capital embedded in corporate governance in a manner that creates a stable basis for the personnel¿s trustworthiness, integrity, and engagement and ethical corporate excellence.Featuring numerous case examples and practical tools and exercises, this book will help the reader learn to:Develop, implement, and cultivate authentic personal governance and corporate governance effectivelyCreate conditions for sustainable corporate governanceIncrease their personal effectivenessDevelop their personal integrity effectively and become a better human beingDevelop ethical personal leadershipDevelop a highly engaged workforce, based on high ethical standardsCreate a high-performance culture and enhance the competitiveness of their organizationCreate conditions for an organizational climate marked by self-guidance, creativity, passion, and ethical behaviorDevelop a culture in which personal integrity and business ethics is a way of lifeSpringer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 268 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -The present volume is a collection of papers presented at the international conference ¿Linguistic Awareness and Dissolution of Diglossiä held in July 2011 at Heidelberg University. The aim is to reevaluate and compare the processes of dissolution of diglossia in East Asian and in European languages, especially in Japanese, Chinese and in Slavic languages in the framework of the asymmetries in the emergence of modern written languages. Specialists from China, Japan, Great Britain, Germany and the U.S. contributed to the volume by introducing their research focusing on aspects of the dissolution of diglossic situations and the role of translation in the process. The first group of texts focuses on the linguistic concept of diglossia and the different processes of its dissolution, while the second investigates the perception of linguistic varieties in historical and transcultural perspectives. The third and final group analyses the changing cultural role and function of translations and their effect on newly developing literary languages.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 276 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -This work provides clear applicationof a newstatisticalmodeling technique thatcan be used to recognize patterns in victimization and prevent repeat victimization. The history of crimeprevention techniques rangefrom offender-based, to environment/situation-based, to victim-based.The authors of this work have found more accurate ways to predict and prevent victimization using astatisticalmodeling, based around crime concentration andsub-group profiling with regard to crime vulnerability levels, to predict areas and individuals vulnerable to crime. Following from this prediction, they propose policing strategies to improve crime prevention based on these predictions. With a combination of immediate actions and longer-term research recommendations, this work will be of interest to researchers and policy makers in focused on crime prevention, police studies, victimology and statistical applications.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 88 pp. Englisch.

Buch. Condizione: Neu. Neuware -Modern information and communication technologies, together with a cultural upheaval within the research community, have profoundly changed research in nearly every aspect. Ranging from sharing and discussing ideas in social networks for scientists to new collaborative environments and novel publication formats, knowledge creation and dissemination as we know it is experiencing a vigorous shift towards increased transparency, collaboration and accessibility. Many assume that research workflows will change more in the next 20 years than they have in the last 200. This book provides researchers, decision makers, and other scientific stakeholders with a snapshot of the basics, the tools, and the underlying visions that drive the current scientific (r)evolution, often called ¿Open Science.¿Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 352 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -Since the peak of the world financial crisis in 2008, compliance management has gained more and more interest from practice and research. In particular the financial service industry is strongly regulated and has to follow specific laws, standards and guidelines. Considering the steadily increasing number of legal requirements in the design of information systems is a challenge to financial service providers. This book investigates the challenges of compliance management in financial industries and provides solutions for a compliant design of information models. From a business process perspective, an approach is presented that enables the automatic checking of business process models. From a supervisory reporting perspective a modeling technique is presented that allows for modeling regulatory data warehouse requirements as well as its analysis. Besides these two perspectives the author provides insights into the perceived relationship of Information Systems and Law.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 108 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -This monograph assesses in depth the application of recursive Bayesian filters in structural health monitoring. Although the methods and algorithms used here are well established in the field of automatic control, their application in the realm of civil engineering has to date been limited. The monograph is therefore intended as a reference for structural and civil engineers who wish to conduct research in this field. To this end, the main notions underlying the families of Kalman and particle filters are scrutinized through explanations within the text and numerous numerical examples. The main limitations to their application in monitoring of high-rise buildings are discussed and a remedy based on a synergy of reduced order modeling (based on proper orthogonal decomposition) and Bayesian estimation is proposed. The performance and effectiveness of the proposed algorithm is demonstrated via pseudo-experimental evaluations.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 148 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -This book is organized into thirteen chapters that range over the relevant approaches and tools in data integration, modeling, analysis and knowledge discovery for signaling pathways. Having in mind that the book is also addressed for students, the contributors present the main results and techniques in an easily accessed and understood way together with many references and instances. Chapter 1 presents an introduction to signaling pathway, including motivations, background knowledge and relevant data mining techniques for pathway data analysis. Chapter 2 presents a variety of data sources and data analysis with respect to signaling pathway, including data integration and relevant data mining applications. Chapter 3 presents a framework to measure the inconsistency between heterogenous biological databases. A GO-based (genome ontology) strategy is proposed to associate different data sources. Chapter 4 presents identification of positive regulation of kinase pathways in terms of association rule mining. The results derived from this project could be used when predicting essential relationships and enable a comprehensive understanding of kinase pathway interaction. Chapter 5 presents graphical model-based methods to identify regulatory network of protein kinases. A framework using negative association rule mining is introduced in Chapter 6 to discover featured inhibitory regulation patterns and the relationships between involved regulation factors. It is necessary to not only detect the objects that exhibit a positive regulatory role in a kinase pathway but also to discover those objects that inhibit the regulation. Chapter 7 presents methods to model ncRNA secondary structure data in terms of stems, loops and marked labels, and illustrates how to find matched structure patterns for a given query. Chapter 8 shows an interval-based distance metric for computing the distance between conserved RNA secondary structures. Chapter 9 presents a framework to explore structural and functional patterns of RNA pseudoknot structure according to probability matrix. Chapter 10 presents methods to model miRNA data and identify miRNA interaction of cross-species and within-species. Chapter 11 presents an approach to measure the importance of miRNA site and the adjacent base by using information redundancy and develops a novel measure to identify strongly correlated infrequent itemsets. The discover association rules not only present important structural features in miRNAs, but also promote a comprehensive understanding of regulatory roles of miRNAs. Chapter 12 presents bioinformatics techniques for protein kinase data management and analysis, kinase pathways and drug targets, and describes their potential application in pharmaceutical industry. Chapter 13 presents a summary of the chapters and give a brief discussion to some emerging issues.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 320 pp. Englisch.

Buch. Condizione: Neu. Neuware -This book develops a naturalistic aesthetic theory that accounts for aesthetic phenomena in mathematics in the same terms as it accounts for more traditional aesthetic phenomena. Building upon a view advanced by James McAllister, the assertion is that beauty in science does not confine itself to anecdotes or personal idiosyncrasies, but rather that it had played a role in shaping the development of science. Mathematicians often evaluate certain pieces of mathematics using words like beautiful, elegant, or even ugly. Such evaluations are prevalent, however, rigorous investigation of them, of mathematical beauty, is much less common. The volume integrates the basic elements of aesthetics, as it has been developed over the last 200 years, with recent findings in neuropsychology as well as a good knowledge of mathematics.The volume begins with a discussion of the reasons to interpret mathematical beauty in a literal or non-literal fashion, which also serves to survey historical and contemporary approaches to mathematical beauty. The author concludes that literal approaches are much more coherent and fruitful, however, much is yet to be done. In this respect two chapters are devoted to the revision and improvement of McAllister¿s theory of the role of beauty in science. These antecedents are used as a foundation to formulate a naturalistic aesthetic theory. The central idea of the theory is that aesthetic phenomena should be seen as constituting a complex dynamical system which the author calls the aesthetic as process theory.The theory comprises explications of three central topics: aesthetic experience (in mathematics), aesthetic value and aesthetic judgment. The theory is applied in the final part of the volume and is used to account for the three most salient and often used aesthetic terms often used in mathematics: beautiful, elegant and ugly. This application of the theory serves to illustrate the theory in action, but also to further discuss and develop some details and to showcase the theory¿s explanatory capabilities.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 240 pp. Englisch.
