Abbreviations adversely affect information retrieval and text comprehensibility. We describe a software tool to decipher abbrevations by finding their whole-word equivalents or “disabbreviations”. It uses a large English dictionary and a rule-based system to guess the most-likely candidates, with users having final approval. The rule-based system uses a variety of knowledge to limit its search, including phonetics, known methods of constructing multiword abbrevations, and analogies to previous abbreviations. The tool is especially helpful for retrieval from computer programs, a form of technical text in which abbreviations are notoriously common; disabbreviation of programs can make programs more reusable, improving software engineering. It also helps decipher the often-specialized abbreviations in technical captions. Experimental results confirm that the prototype tool is easy to use, finds many correct disabbreviations, and improves text comprehensibility. 相似文献

The relation between social dyadic variables such as teacher–student relationship quality (TSRQ) and student achievement have been well-documented within prior work; however, less research has focused on how TSRQ associates with achievement. We used longitudinal structural equation modeling to investigate the extent that teacher self-efficacy mediated the relationship between TSRQ and math achievement for 881 children in the National Institute of Child Health and Human Development Study. Teacher–student closeness had moderate to large positive effects on teacher self-efficacy, whereas teacher–student conflict had small to moderate negative effects on teacher self-efficacy, which then had small positive effects on math achievement. Closeness only had indirect effects on math achievement via teacher self-efficacy, whereas conflict had direct and indirect effects on math achievement. The results were consistent across grades, lending strength to the findings. This study provides researchers and practitioners evidence of an area that can be developed to potentially enhance student success in math. 相似文献

Teacher policy is high on national agendas and countries are seeking to improve schools. Demands on schools and teachers are more complex and it is expected that a larger number of teachers will enter the profession. Studies indicate that the period when teachers are newly qualified is a peak time for leaving the profession. The purpose of this study was to investigate work engagement and teacher efficacy and their relationship to job satisfaction, burnout and the intention to quit among newly qualified teachers. 750 questionnaires were distributed to teachers who had less than six years experience as a teacher after they had completed their teacher education from one university in southern Norway. 192 completed surveys were returned, a response rate of 25.6%. In line with the hypothesis, proposed work engagement and teacher efficacy are positively related to job satisfaction but negatively related to job burnout and the intention to quit. Practical implications of these findings are discussed. 相似文献

Abstract This study explored the relationship between specific social tasks and student perceptions of a sense of community during online group work. A survey instrument was developed, piloted, and deployed to 125 students in six different online classes. Results revealed few significant relationships between each of the five social tasks examined and student perceptions of a sense of community during online group work; however, students reported that some social tasks were important. Students seemed to focus more on completing a task for a grade than seeing group projects as part of developing community to enhance learning. This might reflect a lack of understanding by the students of the importance of social tasks to successful group project completion. 相似文献

How does visual experience change over development? To investigate changes in visual input over the developmental transition from crawling to walking, thirty 13‐month‐olds crawled or walked down a straight path wearing a head‐mounted eye tracker that recorded gaze direction and head‐centered field of view. Thirteen additional infants wore a motion tracker that recorded head orientation. Compared to walkers, crawlers' field of view contained less walls and more floor. Walkers directed gaze straight ahead at caregivers, whereas crawlers looked down at the floor. Crawlers obtained visual information about targets at higher elevations—caregivers and toys—by craning their heads upward and sitting up to bring the room into view. Findings indicate that visual experiences are intimately tied to infants' posture. 相似文献

This study explored university staff's general perceptions of millennial generation college students. Analysis of structured interviews with university professionals revealed that millennial students generally tend to ignore what may be expected of them, resist being accountable for their own actions, and depend on others for problem solving. Implications for college counselors are discussed. 相似文献

ABSTRACTFrail older adults are increasingly being cared for in the community via home- and community-based service (HCBS) programs rather than nursing homes. This policy change challenges psychologists, social workers, and all geriatric practitioners to identify risk and protective factors in order to implement community-based policies in ways which promote the well-being of frail older adults.The present small-scale exploratory study focused on the risk factors of social isolation and loneliness, and the potential of computer use to act as a protective factor. Forty HCBS clients were interviewed about their social convoys, social isolation, and loneliness, and their use of computers. Family members made up the largest percentage of participants’ social convoys (48%). Forty-two percent of participants were found to be socially isolated or at high risk for social isolation. Twenty-five percent of participants used computers and these participants experienced significantly less loneliness and had significantly larger social convoys. All participants were shown a 2.5 -minute video demonstrating a computer programmed to accommodate older adults and 80% expressed interest in using such a program.Future action research projects are suggested to replicate the study’s findings. Such projects could involve collaboration between gerontologists and local area agencies on aging and “service-enriched” affordable senior housing sites. 相似文献

Placing the Internet in information source horizons. A study of information seeking by Internet users in the context of self-development 总被引:1,自引:0,他引:1
The ways in which people perceive the relative value of the Internet when seeking information for self-development purposes were investigated. The concept of information source horizon was introduced, and it is a construct that enables one to put various information sources and channels in an order of preference to meet the requirements of information seeking. The horizon is based on one's conceptions of the characteristics of information sources, particularly their accessibility and quality. The study draws on interviews with eighteen Internet users who positioned various information sources in three zones of relevance. In their information source horizons, human sources such as friends and colleagues were preferred, followed by print media such as newspapers and books: networked sources were ranked third among six source types. Networked sources were favored for easy accessibility and opportunities to save time. The issue of “facilitating everyday life” was emphasized in this context. Also currency, broad repertoire of networked information, and the potential of the Internet to complement other services were valued highly. Critical stands on the Internet were mainly affected by the negative experiences of encountering low quality material. 相似文献

This article outlines the co-operation links of the University of Turku in Finland. Currently it has bilateral agreements with thirty-nine overseas universities plus links with a number of nongovernmental organizations devoted to higher education. The University of Turku is reevaluating these links so as, in the future, to stress those with its immediate international (Baltic) neighbours. It is in the process of contributing to the establishment of a formal Baltic Sea Region University Network and participation in European Union-sponsored Northern Dimension-sponsored projects. The university links parallel and intersect those also established internationally by the city of Turku. International strategies have become a major part of the total activity of the University of Turku. 相似文献
