Book Description
With the advent of the Web along with the unprecedented amount of information available in electronic format, conceptual data analysis is more useful and practical than ever, because this technology addresses important limitations of the systems that currently support users in their quest for information. Concept Data Analysis: Theory & Applications is the first book that provides a comprehensive treatment of the full range of algorithms available for conceptual data analysis, spanning creation, maintenance, display and manipulation of concept lattices. The accompanying website allows you to gain a greater understanding of the principles covered in the book through actively working on the topics discussed. The three main areas explored are interactive mining of documents or collections of documents (including Web documents), automatic text ranking, and rule mining from structured data. The potentials of conceptual data analysis in the application areas being considered are further illustrated by two detailed case studies. Concept Data Analysis: Theory & Applications is essential for researchers active in information processing and management and industry practitioners who are interested in creating a commercial product for conceptual data analysis or developing content management applications.

Book Description
'Although critical research represents a small portion of all IS research, it has always posed insightful challenges to more conventional approaches. This volume assembles a wide array of contributions by leading researchers in the field. The editors clarify the broad range of critical research beyond the seminal contributions that appeared early in IS research, making this an essential guide to contemporary approaches as well as a summation of prior contributions.' – Daniel Robey, Georgia State University, US 'This indispensable book provides an excellent overview of the variety of perspectives that characterize critical research in the information systems field.' – Michael D. Myers, University of Auckland, New Zealand This important Handbook provides a unique overview of information systems (IS) research by focusing on the increasing interest in critical-related issues. Representing a significant step forward in the development of critical perspectives on the IS field, the Handbook draws together original contributions from leading authors who offer alternatives to the current mainstream approaches to IS research. In order to accommodate the various strands of critical understanding, a broad range of views and theoretical standpoints are encompassed, thereby combining theory with practical applications, and offering a valuable source of reference for this emerging area of research. Recent years have witnessed a more explicit focus on critical research and, continuing in that vein, the editors adopt an inclusive approach which considers alternative insights that can arise from critical IS research. Topics explored include, amongst others: • management trends and IS • flexibility, freedom and women's emancipation • 'consuming passions' in the global knowledge economy • critical discourse analysis for the study of information systems • evaluation of e-governance projects in India • rationalities and emotions in IS innovation • capital, information technology and enterprise development • mediated work in global business organizations. Reflecting on key themes and emergent issues in critical information systems research, this Handbook will be invaluable reading for both academics and practitioners with an interest in a critical understanding of information systems from a variety of perspectives.

Book Description
Effective research in educational settings requires collaboration between researchers and school-based practitioners to codesign instruction and assessment, analyze findings to inform subsequent iterations, and make thoughtful revisions. This innovative reference and course text examines the theory and practice of design-based research (DBR), an important methodology for conducting studies in authentic educational contexts. Leading experts provide specific examples of high-quality DBR addressing different research foci, grade levels, and subject areas (literacy/English language arts, math, and science). Applications are presented for curriculum development, intervention, assessment, and digital contexts, as well as teaching second-language learners. Also addressed is DBR’s role in educator preparation, professional development, dissertation research, and technical education.

Book Description
1 DATA ENVELOPMENT ANALYSIS Data Envelopment Analysis (DEA) was initially developed as a method for assessing the comparative efficiencies of organisational units such as the branches of a bank, schools, hospital departments or restaurants. The key in each case is that they perform feature which makes the units comparable the same function in terms of the kinds of resource they use and the types of output they produce. For example all bank branches to be compared would typically use staff and capital assets to effect income generating activities such as advancing loans, selling financial products and carrying out banking transactions on behalf of their clients. The efficiencies assessed in this context by DEA are intended to reflect the scope for resource conservation at the unit being assessed without detriment to its outputs, or alternatively, the scope for output augmentation without additional resources. The efficiencies assessed are comparative or relative because they reflect scope for resource conservation or output augmentation at one unit relative to other comparable benchmark units rather than in some absolute sense. We resort to relative rather than absolute efficiencies because in most practical contexts we lack sufficient information to derive the superior measures of absolute efficiency. DEA was initiated by Charnes Cooper and Rhodes in 1978 in their seminal paper Chames et al. (1978). The paper operationalised and extended by means of linear programming production economics concepts of empirical efficiency put forth some twenty years earlier by Farrell (1957).

Book Description
The overall mission of this book is to provide a comprehensive understanding and coverage of the various theories and models used in IS research. Specifically, it aims to focus on the following key objectives: To describe the various theories and models applicable to studying IS/IT management issues. To outline and describe, for each of the various theories and models, independent and dependent constructs, reference discipline/originating area, originating author(s), seminal articles, level of analysis (i.e. firm, individual, industry) and links with other theories. To provide a critical review/meta-analysis of IS/IT management articles that have used a particular theory/model. To discuss how a theory can be used to better understand how information systems can be effectively deployed in today’s digital world. This book contributes to our understanding of a number of theories and models. The theoretical contribution of this book is that it analyzes and synthesizes the relevant literature in order to enhance knowledge of IS theories and models from various perspectives. To cater to the information needs of a diverse spectrum of readers, this book is structured into two volumes, with each volume further broken down into two sections. The first section of Volume 1 presents detailed descriptions of a set of theories centered around the IS lifecycle, including the Success Model, Technology Acceptance Model, User Resistance Theories, and four others. The second section of Volume 1 contains strategic and economic theories, including a Resource-Based View, Theory of Slack Resources, Portfolio Theory, Discrepancy Theory Models, and eleven others. The first section of Volume 2 concerns socio-psychological theories. These include Personal Construct Theory, Psychological Ownership, Transactive Memory, Language-Action Approach, and nine others. The second section of Volume 2 deals with methodological theories, including Critical Realism, Grounded Theory, Narrative Inquiry, Work System Method, and four others. Together, these theories provide a rich tapestry of knowledge around the use of theory in IS research. Since most of these theories are from contributing disciplines, they provide a window into the world of external thought leadership.

Book Description
Ontology was once understood to be the philosophical inquiry into the structure of reality: the analysis and categorization of ‘what there is’. Recently, however, a field called ‘ontology’ has become part of the rapidly growing research industry in information technology. The two fields have more in common than just their name. Theory and Applications of Ontology is a two-volume anthology that aims to further an informed discussion about the relationship between ontology in philosophy and ontology in information technology. It fills an important lacuna in cutting-edge research on ontology in both fields, supplying stage-setting overview articles on history and method, presenting directions of current research in either field, and highlighting areas of productive interdisciplinary contact. Theory and Applications of Ontology: Computer Applications presents ontology in ways that philosophers are not likely to find elsewhere. The volume offers an overview of current research in ontology, distinguishing basic conceptual issues, domain applications, general frameworks, and mathematical formalisms. It introduces the reader to current research on frameworks and applications in information technology in ways that are sure to invite reflection and constructive responses from ontologists in philosophy.

Book Description
This is an important account of the development of the ‘field-theory’ approach in the social sciences. Harald Mey concentrates on the writers from the 1930s to the present day who have used this approach to the study of the individual and of society, and gives a clear exposition of such ‘field-theory’ application in its many differing forms. In addition, the author shows how a concept which was initially useful in the physical sciences came to be used first by psychologists, and subsequently by sociologists and others in related disciplines, in their search for answers to the problems presented by the study of society. Mey describes how the use of the ‘field-theory’ perspective has fared when applied to specific areas of social research – education, personal relationships, group behaviour. He also compares the ‘field-theory’ approach to the study of societies with the structural/functional approach, and explains why he believes ‘field-theory’ has a number of advantages over the structural/functional approach, especially when it comes to the dynamic problem of social change.

Book Description
Information Systems Research: Relevant Theory and Informed Practice comprises the edited proceedings of the WG8.2 conference, "Relevant Theory and Informed Practice: Looking Forward from a 20-Year Perspective on IS Research," which was sponsored by IFIP and held in Manchester, England, in July 2004. The conference attracted a record number of high-quality manuscripts, all of which were subjected to a rigorous reviewing process in which four to eight track chairs, associate editors, and reviewers thoughtfully scrutinized papers by the highly regarded as well as the newcomers. No person or idea was considered sacrosanct and no paper made it through this process unscathed. All authors were asked to revise the accepted papers, some more than once; thus, good papers got better. With only 29 percent of the papers accepted, these proceedings are significantly more selective than is typical of many conference proceedings. This volume is organized in 7 sections, with 33 full research papers providing panoramic views and reflections on the Information Systems (IS) discipline followed by papers featuring critical interpretive studies, action research, theoretical perspectives on IS research, and the methods and politics of IS development. Also included are 6 panel descriptions and a new category of "bright idea" position papers, 11 in all, wherein main points are summarized in a pithy and provocative fashion.

Book Description
This book sets out to provide postgraduate researchers with guidance on selecting and applying sociotechnical theories to the study of information systems, including how they can be combined to complement each other. Until now it has been difficult to source advice on the application of these theories, and there has been no single book that combines multiple theories as this does. Examining the impacts of technological developments and seeking to understand how humans interact with computers and systems is a dynamic field but can often confuse researchers with the overwhelming number of social theories that are utilised to derive insights. Instead, the author in this book breaks down some of the most popular theories used to underpin information system research, such as activity theory (AT), actor-network theory (ANT), contingency theory (CT), diffusion of innovation (DOI) theory, structuration theory (ST), and the technology acceptance model (TAM). By doing so, this book serves to enable a simpler, faster selection of appropriate theories, and a more effective and productive application that leads to richer, more rigorous research outcomes. Written for postgraduates, researchers, and academics in the fields of information technology and information systems, this book provides a valuable resource of sociotechnical research methodologies that will enable and enhance future studies.
