Open source projects do have requirements; they are, however, mostly informal, text descriptions found in requests, forums, and other correspondence. Understanding such requirements provides insight into the nature of open source projects. Unfortunately, manual analysis of natural language requirements is time-consuming, and for large projects,…

A strong VET system is increasingly seen as essential to overcoming the current economic crisis in Europe. VET is seen as a powerful tool to assist in balancing labour market inefficiencies, increasing youth employment possibilities, and reducing skills mismatch. Its inherent flexibility and closeness to the labour market place VET in a good…

This theoretical review addresses the construct of beliefs in education and English as a foreign language, and their impact when integrating technology. A thorough definition and categorization of teachers' beliefs will be provided. In addition, studies conducted in various educational settings examining the effects of teachers' beliefs and the…

Objectives: With over 1 million children served by the US Child Welfare system at a cost of $20 billion annually, this study examines the economic evaluation literature on interventions to improve outcomes for children at risk for and currently involved with the system, identifies areas where additional research is needed, and discusses the use of…

The educational achievement and attainment of young people in the United States has been a long-standing issue of concern. While analyses of long-term trend data from the National Assessment of Educational Progress (NAEP) show that students in the United States have made gains in reading and mathematics over the past few decades, a sizeable…

Structural models and classes of variables used in parent/child research are identified, and their implications are briefly discussed. The five types of research models appraised are noninteractive, unidirectional, bidirectional, family network, and sociopolitical. It is asserted that, taken together, the typology of models provides a system by…

Reviews the progress of parallel computing in information retrieval (IR) and stresses the importance of the motivation in using parallel computing for text retrieval. Analyzes parallel IR systems using a classification defined by Rasmussen; describes retrieval models used in parallel information processing; and suggests areas of needed research.…

This paper describes a four-dimensional model for the science of knowledge acquisition and a classification system in terms of these dimensions. A summary of the state of the art in terms of the cells generated in a four-dimensional representation of this classification system is presented. The need for better tools for conducting knowledge…

The implications of the 1994 Seels and Richey domain structure for instructional technology (IT) conceptual theory and classification systems, in general, for theory construction are explored. The historical evolution of domains in definitions of the field, the formulation of theory, the nature of taxonomies, the role of conceptual frameworks and…

Reveals the potential usefulness of the "medical model" for social work practitioners. Outlines methods of the medical approach that can be used to improve social services and to avoid wasteful or harmful practice. Suggests social workers having negative attitudes about the medical model should reconsider their attitudes. (Author

Using statistical stereotypes may be a means of improving the effectiveness of information-filtering systems that are based on user profiles. Highlights include information and expert systems that use stereotypes, assigning users to stereotypes, integrating stereotypes into a model for information filtering, and future research. (Author/LRW)

Review of rural social work literature of the 1970's indicates research has primarly followed the naturalistic model defined by Taylor, rather than the positivist approach favored by Fischer. Discussed are: surveys and case studies; ethnographies; participatory/action research; historical research; positivistic research; hypothesis testing…

Describes a databased taxonomy of behaviors that elementary and secondary school teachers use to cope with both internally and externally derived work stress, considers the effectiveness of such behaviors, discusses methods for preparing teachers for working conditions, and points out the value of the taxonomy for future research. (PGD)

Describes a systematic approach to determine interventions which will efficiently increase the retention rates of certain categories of college students using small-sample research methods. Presents six steps designed to reduce student attrition rates among distinct groups of college students. (RC)

Characterizes information retrieval systems in a network environment from a user's perspective along two axes: query and presentation. Several examples of early, current, and developing information retrieval systems are considered within this framework, and Daltext, a prototype system to support research on text-based retrieval systems, is…
