This book reviews all the findings about bonobos and the local people of Wamba village in the Luo Scientific Reserve in the Democratic Republic of the Congo over the last 50 years. In 1973, Takayoshi Kano, a Japanese primatologist, traveled across a vast area of the Congo Basin with a bicycle and found Wamba village to be a promising site to start his first studies on wild bonobos. Since then, many researchers from Japan and all over the world have been working at Wamba, now the longest standing study site, to uncover various aspects of the ecology and behavior of this most recently identified great ape species. The researchers study bonobo behaviors and carry out various activities for the conservation of bonobos. They also conduct anthropological studies of local people who live with bonobos and believe them to be distant relatives from the same family, living in the forest. This book is published in commemoration of 2023 marking the 50th year of study. The main chapters are contributed by active researchers studying bonobos and the local people at Wamba. The book also includes contributions from various eminent researchers who have carried out short-term research or have supported research at Wamba, which helps place these studies of bonobos in a broader primatological or anthropological perspective. This book will be a useful resource for professional researchers in primatology and anthropology, as well as graduate or undergraduate students interested in these research fields.

Although the expression ¿responsibility to future generations¿ is firmly established in public and political vocabulary, its operational meaning and practice are inadequately understood and yet to be systematically evaluated. Moreover, the term has not been successfully translated into viable ethical and theoretical concepts that can guide public policies and actions. How can the modes of governance and established policy priorities become compatible with the well-being of future generations? The primary objective of this book is to identify the conditions of and obstacles to governance for a sustainable future, or future-regarding governance. Governance concerns steering a society over extended periods of time, not responding to particular policy issues. The ideas and strategies proposed by contributors in this book to establish future-regarding governance are based on the theoretical and empirical analyses of the major long-term problems facing advanced democracies in general, and Japan in particular. Japan is an interesting case indeed. Relatively poor climate policy, rapidly decreasing birth rate, aging population, extensive public debt, prolonged economic recession, healthcare and pension systems that urgently require redesigning, hollowing-out of industries and subsequent loss of jobs, deteriorating infrastructures, increasing nuclear waste, and intensifying social polarization have caused a decline in people¿s trust in the government and democratic processes. Currently, Japanese citizens are widely circulating their doubts about the social system¿s sustainability. This book comprises two parts. In Part I, authors from various disciplinary backgrounds examine the idea of governance for a sustainable future from theoretical perspectives. This part discusses issues associated with future-regarding governance that are wicked in nature, such as the philosophical/ethical foundation on which to base the idea of governance for a sustainable future, major impediments to the development of future-regarding governance, and the modes of thinking and action required by leaders and citizens to realize such governance. Chapters in Part II largely focus on the state of long-term governance in Japan. This part uses empirical and in-depth analyses with cross-sectoral and cross-national policy perspectives to identify the state of future-regarding governance in various policy fields and major sectors or organizations mainly in Japan, while also examining strategies and measures to improve their performance. From this perspective, Western democracies and weak democratic regimes elsewhere will be provided with valuable lessons to avoid fatal policy mistakes, thereby improving future-oriented governance worldwide. By combining theoretical discussions on far-reaching issues and empirical analyses of Japanese cases, the book will shed a new light on governance for a sustainable future.

This book confronts the question of immortality: Is human life without immortality tolerable? It does so by exploring three attitudes to immortality expressed in the context of three revolutions, the Soviet, the Nazi and the Communist revolution in China. The book begins with an account of the radical Russian tradition of immortalism that culminates in the thought of Nikolai Fedorov (1829-1903), then contrasting this account with the equally radical finitism of Martin Heidegger (1889-1976). Both these strands are then developed in the context of modern Chinese philosophical thinking about technology and the creation of a harmonious relation to nature that reflects in turn a harmonious relation to mortality, one that eschews the radicality of both Fedorov and Heidegger by discerning a ¿middle way.¿

Nanophotonics and spectroscopy has advanced rapidly in recent years. Experimental research on nanophotonics is very active. In addition to experimental research on the principles and applications of nanophotonics, computational simulation research on its various physical mechanisms and phenomena is equally important. The simulation of the optical properties of molecules or crystals, such as electronic spectra (absorption and emission spectra, etc.) and vibrational spectroscopy has extraordinary guiding significance for experiments. The current computational simulation technology can also explain and analyze the physical mechanisms behind phenomena. However, among the many computational simulation software programs available, the operation methods and application scenarios are different. The barrier for new users to conduct research with computational simulation is high. Even for researchers with some experience, it is not easy to develop a comprehensive understanding of the various software programs, keywords, programming languages and auxiliary programs. This book serves as an introductory book for beginners to get started with the technology, and a handbook for experienced readers to quickly look up for commands and script usage. It is a handy reference for graduate students and researchers engaged in the study of photonics and optics.

This open access book aims to emphasize the potential for Japan, Europe and Indo-Pacific countries including the US to respond to shared domestic and international challenges on finding joint ways to uphold and develop the liberal international order (LIO) in the Asian Pacific region and the world. It explores how these countries and the region (the EU) can work together to promote solidarity and cooperation to advance democratic standards and rules-based norms globally.The US understands the LIO in a political sense and centers its focus on democracy, aiming to build a coalition of democracies opposed to China and Russia which represent a kind of authoritarian axis. The US aims both to defend the LIO and respond to the China challenge and to build a coalition of countries that will do both. In contrast European countries aim at defending the ¿rules-based order¿¿a term preferred because they fear that the concept of the LIO might alienate or antagonize non-democratic countries. They face a dilemma between working with China to reform the LIO or, in seeking to defend it from China, excluding China. Germany and France differ regarding whether to play a passive or active role in the Indo-Pacific, the former choosing to preserve peace and stability for continued exports, and, until recently, doing little to contribute to security. Its views echo those of the ASEAN countries, which are unable or unwilling to take an active role in protecting the LIO. On the contrary France, along with the UK, actively carries out presence operations in the Indo-Pacific. Rather than upholding US dominance, France supports a multipolar order that will also reduce Chinäs influence in the region, with France acting as a balancing power and offering an alternative to the choice between China and the United States. Japan and India show interest in European views with the former leaning more toward its allies, the US and AUKUS, and the latter seeing Europe less as an alternativeto the status quo and more as a complement of QUAD. This book concludes that the US needs to build coalitions rather than forcing allies and neighbors to choose sides, while Japan, Asian countries, and Europeans should more actively reform the LIO.

This book explores future directions in Singaporean education as it moves beyond its historically formative goals of survival, efficiency and performance, and its emphasis on grades and formal credentialing. It examines the future of education via the 4Life framework, a four-form model for purposeful learning centered around social-emotional regulation and the well-being of the individual learner: Life-long learning, the learning that occurs over a learner's lifespan; Life-deep learning, a deep understanding of learned content and adaptive expertise; Life-wide learning, learning in multiple contexts besides the school environment; and Life-wise learning, learning which focuses on the learner's values, morals, character and historical empathy. This book also illustrates how purposeful learning serves to equip learners with the knowledge, skills, dispositions and competencies they need to thrive as adaptive workers in the economy of the future.

The book examines the relationship between imperial examinations and literature from the perspective of restoring the cultural ecology of imperial examinations in Ming China, breaking through the paradigm of pure literature research. This book presents an important practice in adjusting the pattern of literary research. The contents of this book include five mutually independent but supportive parts: 1) the living conditions and careers of the literary attendants; 2) the educational background and school¿s consciousness of the Ming literati; 3) top candidates and Ming literature; 4) genres of imperial examination and the Ming society; 5) exam cheating cases from the perspective of politics and literature. This book will appeal to readers interested in Chinese literature and culture and the imperial examination system in ancient China.

This book provides an original and challenging perspective of religions as abstract complex adaptive systems, using an interdisciplinary approach to try to understand what religions are and how they function, two fundamental issues which, despite an intense struggle from several fields, have not yet been resolved. What is the source of religious belief? How do religions work and what are they made of? Why is religion so important for us that it has survived centuries of scientific progress and secularization? Why are people religious even outside religion? The book addresses these questions using an interdisciplinary approach that seeks to untangle the Gordian knot of defining religion. In short, they can be considered entropy-reducing technologies. What differentiates them from other meaning-producing systems is their configuration which employs specific building blocks as tools for mitigating entropy, which are also subsystems and combine in various ways to build a unique configuration: rituals, myths, taboos, supernatural agents, authority, identity, superstitions, moral obligations, afterlife beliefs and the sacred. As a reaction to perturbances or pressure, systems can collapse. Inspired by Nicholas Nassim Taleb, it is, in this book, referred to as fragility¿the negative reaction of systems to random events, and four parameters can be used to evaluate it in religious systems: monotonicity (the inability to learn from past mistakes), coupling (linking with other systems: such as political or economic), centralization and stress starvation. Several case studies are provided in order to test the theoretical claims made in this book, based on the author's field research in Romania, Japan, North Korea and Mongolia, and offering details that could be of interest to casual readers, students and researchers of religion.

This book provides an account of how local government units in the Philippines engage marginalized and geographically isolated communities in taking part in pre-disaster communication efforts. The book focuses on communities classified by the government as Geographically Isolated and Disadvantaged Areas (GIDA) on the culturally rich island of Mindanao, Philippines. The focus is centered on GIDA communities because they are assumed to receive less information and help in relation to their circumstances. This book accounts for the disaster preparedness communicative conditions of people living in GIDAS and identifies synergies and tensions in the engagement process. As such, specific branches of enquiry focus on how information-seeking and sharing experiences of GIDA communities inform the current practice of community engagement. In taking this research approach, this book deliberately gives voice to these marginalized and often silenced communities. In general, the study examines otherpossibilities (or variables) in the pre-disaster risk communication process that truly engage geographically isolated and socioeconomically disadvantaged communities in disaster risk reduction and management (DRRM).Considering the existing methodologies used to engage local communities in DRRM, this book looks at ways in which bottom-up and top-down approaches could be melded together for a transformational level of engagement in these communities. The novelty of addressing issues concerning geographically isolated communities in a developing country is a research track worthy of being investigated by academics. The book is of interest to students and in development communication and disaster risk communication as well as community engagement practitioners specializing in DRRM. The framework proposed in this book for engaging isolated communities is helpful to practitioners in designing, planning, and implementing pre-disaster communication and community engagement programs.

This book adapts Rasch's approach for quantifying growth on physiological variables, where growth decelerates, to intellectual variables. To apply this approach, it is necessary to construct measurements in a constant unit over the relevant range of the variable. With such measurements, the book illustrates the approach to quantifying growth on six intellectual variables - two intelligences tests and two each of tests of proficiencies in reading comprehension and mathematics. The book discusses how it is not immediately obvious that deceleration on a quantitative scale should also hold for the growth in intellectual variables. It goes on to show that this is indeed the case with all six tests analysed and considers some implications of this feature for understanding intellectual development, in particular the centrality of the growth trajectory set in early life.

This edited book is a comprehensive collection of scientific research on different plants under drought and salt stress conditions. The main focus of this book is to elaborate on the mechanisms being operative in plants under stress and how various biological factors mitigate the adverse effects for better plant productivity. This book covers all physiological, biochemical, and molecular mechanisms operating under drought and saline stresses. The current status and impact of drought and salinity on various crop plants have been elaborated on in different chapters. Agricultural lands are either turning barren or becoming more saline and drought-prone with increasing temperatures, decreasing water tables, untimely rainfall, and other environmental factors. In India, salt-affected soils occupy an area of about 6.73 million ha of which saline and sodic soils constitute roughly 40 and 60%, respectively. All these factors individually or cumulatively, affect the plant growth and development and hence, the crop productivity with the monetary loss. The inbuilt plant's ability with modified/acclimatized mechanisms has been described in various chapters with step-wise descriptions. The role of various plant growth-promoting agents including nano-particles, micro-organisms, metabolites or phytohormones, etc in mitigating adverse effects of drought and salinity has been explained precisely. Updated information on the use of speed breeding, proteomics, epigenetics, and transcriptomics in different crops along with high throughput technologies is included for the cross-talk of various network mechanisms. This book is helpful for the readers in knowing salinity and drought through the physiological, biochemical and genetic, and molecular levels to understand plant behaviour under stress conditions. Also, the book serves as additional reading material for undergraduate and graduate students of agriculture, plant physiology, biochemistry, forestry, and environmental sciences. National and international agricultural scientists and policymakers will also find this to be a useful read.

This book provides a richer understanding of democratic local politics in Indonesia after the implementation of local direct elections in 2005. Co-published with the University of Airlangga Press, it confronts the question as to why incumbent political leaders succeed and fail in their bid for re-election. By focusing on urban and rural districts in East Java, one of the most populated regions in Indonesia, the work unpacks the general trends of local Indonesian politics, drawing from an empirically sound and theoretically well-grounded case study. The author demonstrates that good policy performance does not guarantee the political survival of the incumbent, and reversibly, bad policy performance does not necessarily mean losing political power. It considers the core political strategies of populism, rivalry, and tangibility and cautions that¿rather than helping liberal democracy to grow¿these strategies support patronage-driven democracy. Within this system, a small number of vital protectors and defenders control patronage, and, problematically, exert influential control over the country¿s electoral processes. Relevant to scholars and students in Indonesian studies, and within political science and Asian studies more broadly, this book follows a gripping and nuanced narrative that explains the relationship between policy choices, informal politics, voting behavior, and political survival in Indonesia.
