Qualitative and Quantitative Models in Socio-Economic Systems and Social Work (Studies in Systems, Decision and Control #208)
by José Luis Sarasola Sánchez-Serrano Fabrizio Maturo Šárka Hošková-MayerováThe main purpose of this book is not only to present recent studies and advances in the field of social science research, but also to stimulate discussion on related practical issues concerning statistics, mathematics, and economics. Accordingly, a broad range of tools and techniques that can be used to solve problems on these topics are presented in detail in this book, which offers an ideal reference work for all researchers interested in effective quantitative and qualitative tools. The content is divided into three major sections. The first, which is titled “Social work”, collects papers on problems related to the social sciences, e.g. social cohesion, health, and digital technologies. Papers in the second part, “Education and teaching issues,” address qualitative aspects, education, learning, violence, diversity, disability, and ageing, while the book’s final part, “Recent trends in qualitative and quantitative models for socio-economic systems and social work”, features contributions on both qualitative and quantitative issues. The book is based on a scientific collaboration, in the social sciences, mathematics, statistics, and economics, among experts from the “Pablo de Olavide” University of Seville (Spain), the “University of Defence” of Brno (Czech Republic), the “G. D’Annunzio” University of Chieti-Pescara (Italy) and “Alexandru Ioan Cuza University” of Iaşi (Romania). The contributions, which have been selected using a peer-review process, examine a wide variety of topics related to the social sciences in general, while also highlighting new and intriguing empirical research conducted in various countries. Given its scope, the book will appeal, in equal measure, to sociologists, mathematicians, statisticians and philosophers, and more generally to scholars and specialists in related fields.
Qualitative Computing: Using Software for Qualitative Data Analysis (Cardiff Papers in Qualitative Research)
by Mike FisherAs qualitative researchers incorporate computer assistance into their analytic approaches, important questions arise about the adoption of new technology. Is it worth learning computer-assisted methods? Will the pay-off be sufficient to justify the investment? Which programs are worth learning? What are the effects on the analysis process? This book complements the existing literature by giving a detailed account of the use of four major programs in analyzing the same data. Priority is given to the tasks of qualitative analysis rather than to program capability and the programs are treated as tools rather than as a discipline to be acquired. The key is not what the programs allow researcher to do, but whether the tasks that researchers need to undertake are facilitated by the software. Thus the study develops a user-centred approach to the adoption of computer-assisted qualitative data analysis. The author emphasises qualitative analysis as a creative craft, but one which must increasingly be subject to rigorous methodological scrutiny. The adoption of computer-aided methods offers opportunities, but also dangers and ultimately this book is about the scientific qualitative research. Written in a distinctive and succinct style, this book will be valuable to social science researchers and students interested in qualitative research and in the potential for computer-assisted analysis.
Qualitative GIS: A Mixed Methods Approach
by Sarah Elwood Meghan CopeGeographic Information Systems are an essential tool for analyzing and representing quantitative spatial data. Qualitative GIS explains the recent integration of qualitative research with Geographical Information Systems With a detailed contextualising introduction, the text is organised in three sections: Representation: examines how researchers are using GIS to create new types of representations; working with spatial data, maps, and othervisualizations to incorporate multiple meanings and to provide texture and context. Analysis: discusses the new techniques of analysis that are emerging at the margins between qualitative research and GIS, this in the wider context of a critical review of mixed-methods in geographical research Theory: questions how knowledge is produced, showing how ideas of 'science' and 'truth' inform research, and demonstrates how qualitative GIS can be used to interrogate discussions of power, community, and social action Making reference to representation, analysis, and theory throughout, the text shows how to frame questions, collect data, analyze results, and represent findings in a truly integrated way. An important addition to the mixed methods literature, Qualitative GIS will be the standard reference for upper-level students and researchers using qualitative methods and Geographic Information Systems.

Qualitative Representations: How People Reason and Learn about the Continuous World
by Kenneth D. ForbusAn argument that qualitative representations—symbolic representations that carve continuous phenomena into meaningful units—are central to human cognition.In this book, Kenneth Forbus proposes that qualitative representations hold the key to one of the deepest mysteries of cognitive science: how we reason and learn about the continuous phenomena surrounding us. Forbus argues that qualitative representations—symbolic representations that carve continuous phenomena into meaningful units—are central to human cognition. Qualitative representations provide a basis for commonsense reasoning, because they enable practical reasoning with very little data; this makes qualitative representations a useful component of natural language semantics. Qualitative representations also provide a foundation for expert reasoning in science and engineering by making explicit the broad categories of things that might happen and enabling causal models that help guide the application of more quantitative knowledge as needed. Qualitative representations are important for creating more human-like artificial intelligence systems with capabilities for spatial reasoning, vision, question answering, and understanding natural language.Forbus discusses, among other topics, basic ideas of knowledge representation and reasoning; qualitative process theory; qualitative simulation and reasoning about change; compositional modeling; qualitative spatial reasoning; and learning and conceptual change. His argument is notable both for presenting an approach to qualitative reasoning in which analogical reasoning and learning play crucial roles and for marshaling a wide variety of evidence, including the performance of AI systems. Cognitive scientists will find Forbus's account of qualitative representations illuminating; AI scientists will value Forbus's new approach to qualitative representations and the overview he offers.

Quality Assurance and Accreditation in Distance Education and e-Learning: Models, Policies and Research (Open and Flexible Learning Series)
by Insung Jung Colin LatchemQuality assurance (QA) in open and distance learning (ODL) can be a contentious issue. Some argue that it should be judged by the same criteria and methods as face-to-face education, while others claim that it is so different in its organization, enrolments and operations that conventional QA mechanisms cannot apply. Some advocate the use of specific guidelines and standards for e-learning; others believe that, regardless of the technology, the basic principles of quality teaching and learning should apply. Providers who have enjoyed freedom from external scrutiny may resist attempts at external regulation and auditing and look upon QA as yet another imposition of corporatization and bureaucracy on education. Others see it as a means of establishing a culture of quality, self-reflection and self-improvement. There is little research-based literature to guide policy-makers, managers and practitioners in applying QA in education and training to ensure the right balance is found between accountability and autonomy, as well as assuring quality for the time and costs involved. In this respect, Quality Assurance and Accreditation in Distance Education and e-Learning is a book that is long overdue. It explains what is involved in QA and accreditation in education. It describes and analyzes applications of these practices in open, distance, dual-mode and conventional universities throughout Europe, North America, Africa, and the Asia-Pacific, looking at open schooling, e-learning in conventional schools, non-formal adult and community education, and corporate and small-to-medium enterprises. Quality Assurance and Accreditation in Distance Education and e-Learning is edited and authored by experts with extensive international experience in ODL, e-learning and QA who give careful consideration to the possibilities and challenges involved. The book will be an invaluable guide for all policy-makers, managers, practitioners and researchers in the field.

Quality of Experience Modeling for Cloud Gaming Services (T-Labs Series in Telecommunication Services)
by Saman ZadtootaghajThis book presents the development of a gaming quality model to predict the gaming Quality of Experience (QoE) of players that could be used for planning the network service or quality monitoring of cloud gaming services. The author presents a model that is developed following a modular structure approach that keeps the different types of impairments separately. The book shows how such a modular structure allows developing a sustainable model as each component can be updated by advances in that specific research area or technology. The presented gaming quality model takes into account two modules of video quality and input quality. The latter considers the interactivity aspects of gaming. The video quality module offers a series of models that differ depending on the level of access to the video stream information, allowing high flexibility for service providers regarding the positions of measuring points within their system. In summary, the present book focuses on (1) creation of multiple image/video and cloud gaming quality datasets, (2) development of a gaming video classification, and (3) development of a series of gaming QoE models to predict the gaming QoE depending on the level of access to the video stream information.
