This paper reports the results of a study that investigated Arabic-speaking children’s interaction with the International Children’s Digital Library (ICDL) to find Arabic books on four tasks. Children’s information seeking activities was captured by using HyperCam software. Children’s success was assessed based on a measure the researchers developed. Children’s perceptions of and affective experience in using the ICDL was gathered through group interviews. Findings revealed that children’s information seeking behavior was characterized by browsing using a single function; that is, looking under “Arabic” from the Simple interface pull-down menu. Children were more successful on the fully self-generated, open-ended task than on the assigned and semi-assigned tasks. Children made suggestions for improving the Arabic collection and the design of the ICDL. The findings have implications for practitioners, researchers, and system designers. 相似文献

Diabetes has been classified as a disease of glucose overproduction by tissues, mainly liver and glucose underutilization
by insulin requiring tissues like liver, adipose and muscle due to lack of insulin. There is, however, glucose over utilization
in tissues not dependent on insulin for glucose transport like kidney, nerve and brain. There are serious complications due
to this excess glucose in these tissues and their reversal is important for a good metabolic control and normalisation of
other parameters. Insulin, trace metals and some plant extracts have been used to see the reversal effects of the complications
of diabetes in liver and kidney in experimental diabetes. Almost complete reversal of the metabolic changes has been achieved
in the activities of key enzymes of metabolic pathways in liver and kidney and an effective glucose control has been achieved
suggesting a combination of therapies in the treatment of metabolic disturbance of the diabetic state. 相似文献

The many challenges that school psychologists face inevitably include legal issues. In light of the agreement between the two primary professional organizations for school psychologists that understanding of law is a critical competency, this study analyzed the extent of law‐based articles in leading school psychology journal articles published from 1970 to mid‐2013. The method was a systematic multi‐step search, selection and coding process. The primary findings included that (a) a very small proportion of the articles in five leading school psychology journals contained a notable level of legal content; (b) the number of these articles initially trended upward but stabilized at a lower level during recent decades; (c) assessment and special education were the most frequent subject categories, and (d) the principal sources of law were federal legislation/regulations and court decisions. The discussion includes implications for professional practice and recommendations for follow‐up research. 相似文献

This paper reports the results of a study that examined Arabic-speaking children’s interaction with the International Children’s Digital Library (ICDL). Assessment of the ICDL to Arabic-speaking children as a culturally diverse group was grounded in “representations” and “meaning” rather than in internationalization and localization. The utility of the ICDL navigation controls was judged based on the extent it supported children’s navigation. Most of the ICDL representations and their meanings were found to be highly appropriate for older children but inappropriate for younger ones. The design of the ICDL navigation controls was supportive of children’s navigation. Recommendations for assessing the cross-cultural usability of the ICDL are made and suggestions for system design improvements are provided. 相似文献

Why are some university researchers more likely to create spin-offs than others? Evidence from Canadian universities 总被引：2，自引：1，他引：2
This paper addresses the following question: why are some university researchers more likely to create spin-off companies than others? In order to explain why university researchers create spin-offs, we draw on the resource-based theory of the firm. The study database consists of 1554 university researchers funded by the Natural Sciences and Engineering Research Council of Canada (NSERC). The logistic regression results suggest that the traditional and entrepreneurial visions of university research complement each other when one looks at the resources mobilized by researchers to launch spin-offs. 相似文献

The paper explores the important but neglected field of primary schoolchildren's attitudes towards the environment using a specifically designed scale in Arabic and English. It reports attitude differences towards the environment and three domains -- pollution, waste and animals and plants -- according to nationality and gender. Overall the findings show that environmental education programmes produce only slightly positive attitudes. Consideration is given to the further research required to enhance such programmes. 相似文献

The article studies the differences in knowledge production between academic researchers. In this perspective, it attempts at first to answer the following question: what factors explain differences in knowledge production between Canadian researchers in natural sciences and engineering? After a presentation of some of the empirical evidence related to this first question, a distinction between two types of academic institutions, entrepreneurial versus non‐entrepreneurial universities, is introduced. Drawing from this distinction, four empirical models are suggested to test differences in knowledge production between entrepreneurial and non‐entrepreneurial researchers. The results show, first, that funding, time devoted to teaching activities, research team and individual attributes have a similar but differentiated impact on knowledge production of entrepreneurial and non‐entrepreneurial researchers. Second, there are some unbalanced effects of the variables co‐operation, time devoted to research activities, academic fields and university size on the knowledge production of Canadian researchers on natural science and engineering. 相似文献
