Cox rings are significant global invariants of algebraic varieties, naturally generalizing homogeneous coordinate rings of projective spaces. This book provides a largely self-contained introduction to Cox rings, with a particular focus on concrete aspects of the theory. Besides the rigorous presentation of the basic concepts, other central topics include the case of finitely generated Cox rings and its relation to toric geometry; various classes of varieties with group actions; the surface case; and applications in arithmetic problems, in particular Manin's conjecture. The introductory chapters require only basic knowledge in algebraic geometry. The more advanced chapters also touch on algebraic groups, surface theory, and arithmetic geometry. Each chapter ends with exercises and problems. These comprise mini-tutorials and examples complementing the text, guided exercises for topics not discussed in the text, and, finally, several open problems of varying difficulty.
Originally published in 1995. In securing the future of any democracy, it is vital that the education service should provide an effective introduction to citizenship by means of a high quality and empowering curriculum in educational institutions organized and administered according to democratic principles. In this volume, educators with a variety of backgrounds and experience gained in educational institutions in both Russia and western countries address the question of the conception, justification and implementation of the idea of 'education for democracy'. This is the first publication to emerge from a collaboration of Russian and Western educators in recent times and is an enthralling account of education in countries with wide social, political and historical differences yet having common ground to share over the creation and management of their school systems.
Cremona Groups and the Icosahedron focuses on the Cremona groups of ranks 2 and 3 and describes the beautiful appearances of the icosahedral group A5 in them. The book surveys known facts about surfaces with an action of A5, explores A5-equivariant geometry of the quintic del Pezzo threefold V5, and gives a proof of its A5-birational rigidity.
The authors explicitly describe many interesting A5-invariant subvarieties of V5, including A5-orbits, low-degree curves, invariant anticanonical K3 surfaces, and a mildly singular surface of general type that is a degree five cover of the diagonal Clebsch cubic surface. They also present two birational selfmaps of V5 that commute with A5-action and use them to determine the whole group of A5-birational automorphisms. As a result of this study, they produce three non-conjugate icosahedral subgroups in the Cremona group of rank 3, one of them arising from the threefold V5.
This book presents up-to-date tools for studying birational geometry of higher-dimensional varieties. In particular, it provides readers with a deep understanding of the biregular and birational geometry of V5.
Crisis is a burning issue; this is not a phenomenon, which can be conquered forever. Current approach to crisis is an optimized collaboration, which allows for manageable, measurable and predictable software development. Crisis is a new reality to live and work with. The current software development crisis dates back to the 1960s. The root cause of crisis is misbalance between resources and options. Understanding the nature of crisis helps to understand the reasons for the future crises.
This book is a navigator in lifecycle models, methodologies, principles and practices for predictable and efficient software development in crisis, i.e. under rapid requirement changes, resource deficit and other uncertainties. Therefore, the starting chapters suggest the major approaches to software development and their applicability in crisis. Further narration is case-based; it involves large-scale software implementations in different industries and knowledge transfer processes in IT education. The book suggests a set of principles that potentially marry the client’s and the developer’s views of the future software product in order to avoid or to mitigate the crisis.
The book will be helpful for students, postdocs, theorists and practitioners in software development. It suggests approved principles and practices of crisis management for software development.
The purpose of the manual is to develop analytical reading skills based on business materials, followed by a summary. The method of logical schemes is based on the text analysis algorithm, which allows the student to consistently work out the text, highlight key information and establish logical connections between the main ideas of the text.
Intended to bridge the gap between the latest methodological developments and cross-cultural research, this interdisciplinary resource presents the latest strategies for analyzing cross-cultural data. Techniques are demonstrated through the use of applications that employ cross national data sets such as the latest European Social Survey. With an emphasis on the generalized latent variable approach, internationally–prominent researchers from a variety of fields explain how the methods work, how to apply them, and how they relate to other methods presented in the book. Syntax and graphical and verbal explanations of the techniques are included. A website features some of the data sets and syntax commands used in the book.
Applications from the behavioral and social sciences that use real data-sets demonstrate:The use of samples from 17 countries to validate the resistance to change scale across these nations How to test the cross-national invariance properties of social trust The interplay between social structure, religiosity, values, and social attitudes A comparison of anti-immigrant attitudes and patterns of religious orientations across European countries.
The book is divided into techniques for analyzing cross-cultural data within the generalized-latent-variable approach: multiple-group confirmatory factor analysis and multiple-group structural equation modeling; multi-level analysis; latent class analysis; and item-response theory. Since researchers from various disciplines often use different methodological approaches, a consistent framework for describing and applying each method is used so as to cross ‘methodological borders’ between disciplines. Some chapters describe the basic strategy and how it relates to other techniques presented in the book, others apply the techniques and address specific research questions, and a few combine the two. A table in the preface highlights for each chapter: a description of the contents, the statistical methods used, the goal(s) of the analysis, and the data set employed.
This book is intended for researchers, practitioners, and advanced students interested in cross-cultural research. Because the applications span a variety of disciplines, the book will appeal to researchers and students in: psychology, political science, sociology, education, marketing and economics, geography, criminology, psychometrics, epidemiology, and public health, as well as those interested in methodology. It is also appropriate for an advanced methods course in cross-cultural analysis.

This book explores controversial education issues in a variety of international contexts. Controversial issues constitute a normative anchor within citizenship education curriculum. The degree to which they are subjected to reflection has profound implications for the viability and vibrancy of democratic societies. Discussing controversial issues can overlap with ideological battles outside the school, or within it, but it trumps those given the essential mandate for students to deliberate about the common good, take a stand on issues, and explore ideas with multiple sources and perspectives. Every society privileges, in some form, the topics available for inquiry and discussion within their schools. Curriculum guidelines, exams, textbooks, colleagues, administrators, standards, teacher preparation, and local communities all influence teacher decisions and weigh upon the extent to which this normative mandate is realized. Yet, research about these decisions is typically tied to a singular context. In response, this book draws upon the work of an international team of authors and cinches together single-case and context-specific studies on the pathways and challenges to teaching controversial issues. It offers transferable, grounded, theoretical insights for educational policymakers and lawmakers, as they work to strengthen democratic citizenship education. The book explores controversial education issues in the United States, Australia, China, Ghana, Kenya, Macedonia, Northern Ireland, Philippines, Singapore, South Africa, South Korea, and Turkey.

The consequences of globalization and mass migration are such that, it has been estimated, over 200 million people are living in countries other than where they were born. And as formerly homogeneous societies evolve into multicultural entities with traditional social and geographic boundaries giving way to increasingly complex representations of identity, new-and urgent-questions for psychologists, social scientists, and policymakers arise. As research in and around cross-cultural psychology burgeons as never before, this new four-volume collection from Routledge meets the need for an authoritative reference work to make sense of a rapidly growing and ever more complex corpus of literature. Edited by two leading scholars, the collection is organized into four principal sections: Basic Issues; Theory and Method; Substantive Findings in Basic Processes; and Substantive Findings in Applied Issues. Cross-Cultural Psychology provides a one-stop 'mini library' of foundational and canonical work. The collection also includes cutting-edge analyses and discussions of theory and research, alongside major works addressing policy implications
While gender issues are almost always multidimensional and complex, this book discusses them from a cultural angle and with a focus on crossing borders, to represent their concepts meaningfully and to illuminate their realities as sharply as possible. Its five parts detail specific aspects and issues within that focus, namely communication, literary representation, equality and violence, work and politics, and cross-cultural connections. This combination of a wide topical range with specific discussions of gender issues makes the volumes insights worthwhile for a wide range of readers, from individuals and groups engaging with current gender challenges, to institutional and political decision-makers entrusted with improving gender relations on national or international levels, up to social, economic or educational institutions empowered to implement such solutions in everyday reality. Its unity in diversity contributes to gender and cultural studies by offering considerations and conclusions that are specific and generalizable, theoretically robust and empirically tested, professionally rational and poetically ravishing.
