Grouping Multidimensional Data : Recent Advances in Clustering
Clustering is one of the most fundamental and essential data analysis techniques. Clustering can be used as an independent data mining task to discern intrinsic characteristics of data, or as a preprocessing step with the clustering results then used for classification, correlation analysis, or anomaly detection.

Group-based Cryptography
This book is about relations between three different areas of mathematics and theoretical computer science: combinatorial group theory, cryptography, and complexity theory. It is explored how non-commutative (infinite) groups, which are typically studied in combinatorial group theory, can be used in public key cryptography. It is also shown that there is a remarkable feedback from cryptography to combinatorial group theory because some of the problems motivated by cryptography appear to be new to group theory, and they open many interesting research avenues within group theory.
Group theory : Application to the physics of condensed matter
Every process in physics is governed by selection rules that are the consequence of symmetry requirements. The beauty and strength of group theory resides in the transformation of many complex symmetry operations into a very simple linear algebra. This concise and class-tested book has been pedagogically tailored over 30 years MIT and 2 years at the University Federal of Minas Gerais (UFMG) in Brazil. The approach centers on the conviction that teaching group theory in close connection with applications helps students to learn, understand and use it for their own needs. For this reason, the theoretical background is confined to the first 4 introductory chapters (6-8 classroom hours). From there, each chapter develops new theory while introducing applications so that the students can best retain new concepts, build on concepts learned the previous week, and see interrelations between topics as presented.
Group rights as human rights : A liberal approach to multiculturalism
Liberal theories have long insisted that cultural diversity in democratic societies can be accommodated through classical liberal tools, in particular through individual rights, and they have often rejected the claims of cultural minorities for group rights as illiberal. Group Rights as Human Rights argues that such a rejection is misguided. Based on a thorough analysis of the concept of group rights, it proposes to overcome the dominant dichotomy between "individual" human rights and "collective" group rights by recognizing that group rights also serve individual interests.
Group interventions in schools : Promoting mental health for at-risk children and youth
Children who are labeled at-risk often suffer from severe deficiencies in cognitive, affective, and behavioral skills that, if unaddressed, may lead to limited prospects for future success and well-being. Tapping into the therapeutic potential of groups, this volume presents the theory and practice of cognitive-oriented group-centered counseling – combining intrinsic motivation, efficacy retraining, and targeted play therapy and social role-playing – that can be implemented to help children build core social skills and emotional regulation to complement their classroom instruction.
Group Coordination and Cooperative Control
Group coordination and cooperative control are topics currently receiving a lot of interest. Coordinating the motion of a group of relatively simple and inexpensive agents can cover a larger operational area and achieve complex tasks exceeding the abilities of a single agent. This enables applications such as teams of robots for de-mining operations, aerospace formation flying for survey, fleets of AUVs for oceanographic mapping, and ships doing coordinated towing operations. This volume contains the contributions of the workshop. The book covers a wide range of subjects within the area of group coordination and cooperative control, and forms a valuable and up-to-date text on the newer trends in group coordination and cooperative control.
Group B Coxsackieviruses
This monograph reviews information published since 1997 on the group B coxsackieviruses (CVB), a large and important group of human enteroviruses. The CVB were discovered in the mid-20th century, during the search for other poliovirus types, and within a very few years of this discovery, the CVB had been implicated as causes of human myocarditis and pancreatitis. The study of the CVB is still inextricably linked with the fate of their well-known relatives, the polioviruses, for as poliovirus eradication proceeds around the world, the CVB emerge more prominently as the enteroviruses best suited for continuing studies in enteroviral molecular biology as well as understanding the mechanisms underlying enteroviral pathogenesis. This volume reviews and presents modern views on the spectrum of CVB biologies, from interaction of the virus with its receptor through replication, speciation, and induction of disease.
Group 13 Chemistry III : Industrial Applications
The present issue of Structure and Bonding is dedicated to applied group 13 chemistry, particularly for the elements boron and aluminum, and to a lesser degree gallium and indium. Although boron is a trace element (0.01 g kg 1) in the earth's crust, it has been concentrated in a few locations by geochemical processes and is relatively easy to mine as borax. Aluminum, on the other hand, is the most abundant metal in the earth's crust (82 g kg 1) and dispersed widely throughout the globe. In the chapter Schubert explains the close relationship between the basic properties of the boron compounds and their associated uses. The remaining four chapters focus, to some degree, on aluminum. Since a great deal of literature exists in this area, these chapters are more focused on areas of emerging utility, and contain a great deal of fundamental information. Uhl's contribution in Chapter 2 provides basic synthesis and structural information for aluminum and gallium hydrazides. These types of compounds are being explored as potential molecular precursors to metal nitrides such as the important blue green laser material gallium nitride.
Group 13 Chemistry I : Fundamental New Developments
Depending on the use of the elements, the resulting work can be described under any heading of chemistry. The group 13 elements have been special in this regard due to the very unique characters of the constituent elements. Thus, there is a dramatic change in the properties of the elements when proceeding through the series, B, A1, Ga, In, T1. This difference is one of the main reasons why these elements have seen, and continue to see, such widespread usage in such disparate applications as organic synthesis, electronic and structural materials, and catalysis, to name but a few.
Graphs, Dioids and Semirings : New Models and Algorithms
The primary objectives of GRAPHS, DIOÏDS AND SEMIRINGS: New Models and Algorithms are to emphasize the deep relations existing between the semiring and dioïd structures with graphs and their combinatorial properties, while demonstrating the modeling and problem-solving capability and flexibility of these structures. In addition the book provides an extensive overview of the mathematical properties employed by "nonclassical" algebraic structures, which either extend usual algebra (i.e., semirings), or correspond to a new branch of algebra (i.e., dioïds), apart from the classical structures of groups, rings, and fields.
Governing knowledge : A study of continuity and change in higher education : A Festschrift in Honour of Maurice Kogan
In this book, an international group of leading higher education researchers draw on a wealth of social theory and comparative, empirical research to analyse current developments and their implications. Different contributions focus on different levels of higher education, the system, the institution and the academic practitioner, in different national and international contexts. However, strong common themes bind these contributions together. They include not only the significance of massification, globalisation, neo-liberalism and managerialism for the governance of higher education, its knowledge and values, but also the complexities of change processes, the importance of context and history and the strength of the stabilities that remain.
Governance of Communication Networks : Connecting Societies and Markets with IT
The articles collected in this book shed light on several aspects that are crucial for the success of global communication networks: they range from an appropriate framework for regulation and suitable strategies of firms that act as international players, to the inclusion of customers in defining product and service strategies, and from problems of access to advanced technology and networks for all groups in society regardless of their social status or geographical location to the role of new technologies in facilitating universal communication.
Globalization and Summit Reform : An Experiment in International Governance
This account of the 'L-20 project' describes and analyses a 3-year mobilization designed as an alternative to the political deadlocks preventing progress on critical global issues. The L-20 would include leaders from the existing G-countries, augmented by key regional powers such as China, Brazil, India, South Africa and Egypt. The book traces the origins and findings of the project, which generated a broad array of cutting-edge research and over twenty substantive, action-oriented workshops involving hundreds of experts and practitioners around the world. The workshop series examined in detail the operational possibilities for a Leaders Group addressing a range of issues, including infectious disease control, climate change/global warming, energy security, nuclear proliferation, management of international financial crises, and the provision of safe drinking water and sanitation, to name just a few.
Globalization and culture at work : Exploring their combined glocality
Behaviour at work can no longer be stereotyped as global or local – modern or traditional – with very little in-between. Instead work behaviour is a complex interplay between Global and Local values. It takes place in a Glocality. Thus individual achievement co-exists with group aspirations, pay diversity takes place in a social context, teamwork reflects cultural narrative, and labour mobility is bound by community bias. Globalization and Culture at Work: Exploring their Combined Glocality breaks new ground by exploring such glocalities, and the implications they create for managing human potential better. The volume is essential reading for researchers, managers, culturalists and consultants of work behaviour alike.
Global Political Demography : The Politics of Population Change
This book draws the big picture of how population change interplays with politics across the world from 1990 to 2040.
