Taschenbuch. Zustand: Neu. Neuware -The book develops a ¿double comparison¿ analytical framework to compare the organisation of labour and leisure in the three respective generations, proceeding, on the one hand, diachronically along the historical time, that is, the pre-collective era, collective era and reform era, and synchronically along the women¿s life stages on the other. In so doing, the book links women¿s shifting role in changing family/household forms with broader socio-economic, political, demographic and cultural changes. Moreover, it employs a holistic perspective to reflect changing patterns in women¿s labour and leisure by disrupting the remunerated/unremunerated, home/labour, within/outside household and labour/leisure dichotomies, and exploring the interrelations between them.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 256 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -The emerging biotechnologies have significantly advanced the study of biological mechanisms. However, biological data usually contain a great amount of missing information, e.g. missing features, missing labels or missing samples, which greatly limits the extensive usage of the data. In this book, we introduce different types of biological data missing scenarios and propose machine learning models to improve the data analysis, including deep recurrent neural network recovery for feature missings, robust information theoretic learning for label missings and structure-aware rebalancing for minor sample missings. Models in the book cover the fields of imbalance learning, deep learning, recurrent neural network and statistical inference, providing a wide range of references of the integration between artificial intelligence and biology. With simulated and biological datasets, we apply approaches to a variety of biological tasks, including single-cell characterization, genome-wide association studies, medical image segmentations, and quantify the performances in a number of successful metrics.The outline of this book is as follows. In Chapter 2, we introduce the statistical recovery of missing data features; in Chapter 3, we introduce the statistical recovery of missing labels; in Chapter 4, we introduce the statistical recovery of missing data sample information; finally, in Chapter 5, we summarize the full text and outlook future directions. This book can be used as references for researchers in computational biology, bioinformatics and biostatistics. Readers are expected to have basic knowledge of statistics and machine learning.Springer-Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 124 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -This book discusses the smooth integration of optical and RF networks in 5G and beyond (5G+) heterogeneous networks (HetNets), covering both planning and operational aspects. The integration of high-frequency air interfaces into 5G+ wireless networks can relieve the congested radio frequency (RF) bands. Visible light communication (VLC) is now emerging as a promising candidate for future generations of HetNets. Heterogeneous RF-optical networks combine the high throughput of visible light and the high reliability of RF. However, when implementing these HetNets in mobile scenarios, several challenges arise from both planning and operational perspectives. Since the mmWave, terahertz, and visible light bands share similar wave propagation characteristics, the concepts presented here can be broadly applied in all such bands.To facilitate the planning of RF-optical HetNets, the authors present an algorithm that specifies the joint optimal densities of the base stations by drawing on stochastic geometry in order to satisfy the users¿ quality-of-service (QoS) demands with minimum network power consumption. From an operational perspective, the book explores vertical handovers and multi-homing using a cooperative framework. For vertical handovers, it employs a data-driven approach based on deep neural networks to predict abrupt optical outages; and, on the basis of this prediction, proposes a reinforcement learning strategy that ensures minimal network latency during handovers. In terms of multi-homing support, the authors examine the aggregation of the resources from both optical and RF networks, adopting a two-timescale multi-agent reinforcement learning strategy for optimal power allocation.Presenting comprehensive planning and operational strategies, the book allows readers to gain an in-depth grasp of how to integrate future coexisting networks at high-frequency bands in a cooperative manner, yielding reliable and high-speed 5G+ HetNets.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 136 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -This book provides an interesting review of Japanese monetary policies after the bubble economy. The Bank of Japan was the first central bank in advanced economies to implement the unconventional monetary policies during the period. After the Lehman shock, most advanced economies also carried out similar monetary policies to boost their own economies. The Japanese experience in the 1990s and 2000s no doubt played a key role during the period. Although various aspects of the experiences have been examined, not many books have been published based on intensive discussions between the macro and monetary theorists who have been active in academics and the practitioners who have actually been involved in monetary policy. This small but important book has focused on the Japanese experience. Evaluation of that experience found that three solid pillars are of crucial importance: theory, institution, and experience. Those form the basis of the book, without theory, no policies will be formulated and implemented, and implementation depends crucially on institution. Chapter 1 provides a clear theoretical background for the unconventional monetary policies and inflation targeting. Chapter 2 intensively explores the meaning and desirability of the independence of central banks. Chapter 3 reviews the consequences of the Japanese monetary policies in recent decades in comparison with those in other advanced economies.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 76 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -This book studies Australia, a country characterized by the highest concentration of domestic photovoltaic systems. In addition, the high level of solar energy that Australia receives makes these systems a significant part of its energy mix. International electricity system managers take note; your systems are heading this way. The energy transition is an emerging field, and few texts have been published that can help energy planners as this book does. The research presented is sociotechnical in nature, and reveals that the main challenge in the energy transition is its emerging social role. Very few works combine the social and technical fields of energy. Given its scope, the book will appeal to readers interested in policy, regulation, and energy systems, including government employees involved in energy system management all around the world.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 212 pp. Englisch.

Buch. Zustand: Neu. Neuware -This book reframes commemoration through distinctly geographical lenses, locating it within experiential and digital worlds. It interrogates the role of power in representations of memory and shows how experiences of commemoration sit within, alongside and in contrast to its official normative forms. The book charts how memories, places and experiences of commemoration play out and have, or have not, changed in and through a digital world. Key to the book¿s exploration is a new epistemology of memory, underpinned by an embodied research approach.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 168 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -The book comprises three chapters, with each chapter assigned various type data such as time series data, cross sectional data and panel data. The purpose of this book is to explore the economic and social determinant factors of fertility. Unlike many previous empirical analyses of fertility and the related demographic events, this research has three characteristics. The first is that the relationship between fertility and labor participation by females is thoroughly considered, with much discussion about the structural change between those factors. The second is that time series analysis such as the Bayesian vector autoregressive (BVAR) model or co-integration concepts is applied to explore the determinant factors of fertility. The third is that the effectiveness of public policies related to improve fertility is confirmed. In recent years, micro-econometric analysis has become popular; however, this book takes another approach from the perspective of macro- or semi-macro-econometrics.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 88 pp. Englisch.

Buch. Zustand: Neu. Neuware -This book explores the role of social and epistemic diversity in science, technology, and medicine in the 21st century. It argues that most contemporary endeavours to democratize science are epistemically conservative. Using illustrative case studies, Dr Dana Mahr shows how epistemic diversity can contribute to a renewal of the production of scientific knowledge. Her exploration of online self-help cultures, radical feminist health movements, and grassroots environmentalism in Thailand emphasize that ¿experiential knowledge¿ and ¿performativity¿ are important epistemic strategies for marginalized social groups to critically engage with institutionalized knowledge.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 152 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -This book provides a key to understanding why there was an increase in extra-marital fertility in Japan from the 1990s to the 2010s, particularly between 1995 and 2015, and the factors which contribute to the multistratification of unmarried mothers, the number of which has increased ensuingly. It also allows for international comparison by providing data on outcomes of extra-marital childbirth.Previously, it was believed that the idea of a ¿second demographic transition¿ did not apply to Japan, which had a relatively low rate of extra-marital fertility. However, more recently, though still at a low level, a subtle but gradual rise is seen in the number of women who become unmarried mothers as a result of births outside marriage.This trend suggests that the social environment surrounding pregnancy, childbirth, and marriage is changing. In this book, various data such as national statistics, nationwide surveys, and media discourse are analysed with a view torevealing the factors affecting unmarried women¿s decisions when they discover they are pregnant. Various matters are discussed, such as changes in sexual activity and contraceptive use, advance in reproductive technology, the law and government policies pertaining to adoption, social consciousness towards unwed mothers, the change in perception of abortion from the religious perspective, and difference of socioeconomic status depending on the women¿s occupation.Facts from vital statistics are first laid out, showing that, while abortion has consistently been on the decrease from the 1990s onward, shotgun marriages have peaked out. Adoption is rare and remains very small in proportion, while extra-marital fertility is on the rise. The author then points to the possibility that greater lenience found in the social consciousness towards unwed mothers in recent years is a pull factor for the increase in extra-marital fertility. Further, by analysing vital statistics, it is revealed that the probability of becoming a mother without marrying changed with the woman¿s occupation, explicable by the stability of employment and level of income, and that between 1995 and 2015, the effects of the job factor are changing.If we assume that, unlike the first demographic transition model, the ¿second demographic transition¿ may show a similar direction but be on a different scale according to the country, it is possible to say that Japan too is experiencing the ¿second demographic transition¿.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 112 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -This book deals with the events leading up to the 1936 Popular Olympics which would have united the Popular Front in opposition to the Berlin Olympics. It also discusses the days after the outbreak of the Spanish Civil War which began on the same day the games were due to start. Using a variety of primary and secondary sources, the book traces the biographies of several Popular Olympians who would go on to volunteer in the Spanish Civil War. The book also examines the planned events and locations for the Popular Olympics as well as the international funding that the games secured. The book argues that the events were a departure from Workers¿ Sport as well as the IOC¿s Olympic games and represented an important cultural manifestation of the Popular Front.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 160 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -This second volume continues the study on asymptotic convergence of global solutions of parabolic equations to stationary solutions by utilizing the theory of abstract parabolic evolution equations and the ¿ojasiewicz¿Simon gradient inequality. In the first volume of the same title, after setting the abstract frameworks of arguments, a general convergence theorem was proved under the four structural assumptions of critical condition, Lyapunov function, angle condition, and gradient inequality. In this volume, with those abstract results reviewed briefly, their applications to concrete parabolic equations are described.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 140 pp. Englisch.
