Recording search histories, presenting them to the searcher, and building additional interface tools on them offer many opportunities for supporting user tasks in information seeking and use. This study investigated the use of search history information in legal information seeking. Qualitative methods were used to explore how attorneys and law librarians used their memory and external memory aids while searching for information and in transferring to information use. Based on the findings, interface design recommendations were made for information systems.  相似文献

Both Danish and English agriculture underwent fundamental restructuring during the second half of the 19th century, and in both cases the dairy sector made great advances. However, the two agricultural industries differed in aims and strategies, and crucially in the extent to which new technologies and scientific methods were implemented. Economic historical analysis is insufficient to explain why the Danish and English dairy industries developed in different ways, and how Danish butter achieved success in the competitive English market. However, with a focus on the role of science and a scientific understanding of the development of these two dairy industries, all becomes clear.  相似文献

We report how 47 pre-service teachers during their preschool placement in Sweden identify events related to gender and emerging science. We analysed their reflections on the situations with Gee’s Discourse analysis. Two dominant discourse models were identified: the Discourse Construare, where pre-service teachers assumed that children have potential interests in a variety of subjects, and the Discourse Essentia, where children were regarded to have a stable core identity. In the latter discourse, the pre-service teachers’ task would be to encourage the children to be who they are. The analysis found a connection between pre-service teachers’ views of the child and whether gender stereotypes were reproduced or counteracted. The Discourse Essentia is in conflict with the goal in the Swedish national curriculum that all children should learn science. We discuss how the different discourses affect whether children are stimulated or inhibited in their emerging science activities and interests. Based on the results from an analysis of answers reflecting the Discourse Construare, we have designed a model illustrating a process for gender-aware teaching.  相似文献

If immigrants are to get the best results in theirsocial and work worlds, they must possess not only therelevant cultural information, but also the requisitebehavioural skills inherent in the novel social rolesthat people acquire as members of the new country. This paper argues that the preferred training modelfor developing such competencies is one which utilizesrole-based learning in groups and incorporates aspectsof group counselling theory and practice. Effectivefacilitators of these immigrant groups should beskilled group leaders competent in taking participantsthrough the four stages - alliance building, culturalmapping, coaching and practice, and contract setting - involved in teaching each of severalkey sociocultural competencies. Group leaders will need to performparticular types of task and maintenance functions,and facilitate the development of group inclusion,control, and trust. To achieve this, facilitators arerecommended to use a range of micro skills for groupleading, processing, and counselling.  相似文献

ABSTRACT

The Physical Activity Neighborhood Environment Scale (PANES) has been used internationally; however, PANES properties have not been assessed in all geographical contexts. Our objectives were to assess the reliability and validity of an online and paper version of the PANES in Canadian adults. Reliability was estimated using intraclass correlation coefficients (ICC), percent of overall agreement (p0) and Cohen’s Kappa coefficient (κ). Lower 95% confidence interval (CI) ICC ranged from 0.10 to 0.70. Lower 95%CI for κ statistics ranged from ?0.20 to 0.64 and p0 ranged from 80.1% to 95.7%. Cronbach’s alpha coefficients (α) estimated internal consistency of the PANES (α = 0.58 for the paper version and α = 0.55 for the online version). Mean scores for the PANES Built Environment Index (BEI) significantly differed by neighborhood street pattern (p < .05). The PANES administrated via paper or online provides reliable overall agreement and valid estimates of the self-reported neighborhood built environment supportiveness of physical activity.  相似文献

The current study describes the storybook reading behaviors of 45 preschoolers [30 with language impairment (LI) and 15 with typical language (TL)] and their mothers. Each dyad was observed reading a storybook within their homes, and sessions were subsequently coded for indicators of emotional and instructional quality as well as for child participation. Mothers of children with LI showed lower levels of emotional support than mothers of children with TL, although all mothers exhibited similar quality of instruction. The two groups of children were equally enthusiastic about the book; however, children with LI were observed to be less compliant than children with TL and showed a trend to be less persistent. For the children with LI, participation in the book reading task was found to be high only when mothers’ behaviors were observed to be highly sensitive in nature, demonstrating the importance of exposing children to maternal behaviors that are responsive to their unique abilities and needs.  相似文献

Endothelial cell death due to increased reactive oxygen species(ROS) may contribute to the initial endothelial injury,which promotes atherosclerotic lesion formation.Piper sarmentosum(PS),a natural product,has been shown to have an antioxidant property,which is hypothesized to inhibit production of ROS and prevent cell injury.Thus,the present study was designed to determine the effects of PS on the hydrogen peroxide(H2O2)-induced oxidative cell damage in cultured human umbilical vein endothelial cells(HUVECs).In this experiment,HUVECs were obtained by collagenase perfusion of the large vein in the umbilical cord and cultured in medium M200 supplemented with low serum growth supplementation(LSGS).HUVECs were treated with various concentrations of H2O2(0-1000 μmol/L) and it was observed that 180 μmol/L H2O2 reduced cell viability by 50% as denoted by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide(MTT) assay.Using the above concentration as the positive control,the H2O2-induced HUVECs were concomitantly treated with various concentrations(100,150,250 and 300 μg/ml) of three different extracts(aqueous,methanol and hexane) of PS.Malondialdehyde(MDA),superoxide dismutase(SOD),catalase(CAT) and glutathione peroxidase(GPX) levels showed a significant increase(P0.05) in HUVECs compared to the negative control.However,PS extracts showed a protective effect on HUVECs from H2O2-induced cell apoptosis with a significant reduction in MDA,SOD,CAT and GPX levels(P0.05).Furthermore,PS had exhibited ferric reducing antioxidant power with its high phenolic content.Hence,it was concluded that PS plays a beneficial role in reducing oxidative stress in H2O2-induced HUVECs.  相似文献

The paper presents comparative analyses of two publication point systems, The Norwegian and the in-house system from the interdisciplinary Danish Institute of International Studies (DIIS), used as case in the study for publications published 2006, and compares central citation-based indicators with novel publication point indicators (PPIs) that are formalized and exemplified. Two diachronic citation windows are applied: 2006-07 and 2006-08. Web of Science (WoS) as well as Google Scholar (GS) are applied to observe the cite delay and citedness for the different document types published by DIIS, journal articles, book chapters/conference papers and monographs. Journal Crown Indicator (JCI) calculations was based on WoS. Three PPIs are proposed: the Publication Point Ratio (PPR), which measures the sum of obtained publication points over the sum of the ideal points for the same set of documents; the Cumulated Publication Point Indicator (CPPI), which graphically illustrates the cumulated gain of obtained vs. ideal points, both seen as vectors; and the normalized Cumulated Publication Point Index (nCPPI) that represents the cumulated gain of publication success as index values, either graphically or as one overall score for the institution under evaluation.The case study indicates that for smaller interdisciplinary research institutions the cite delay is substantial (2–3 years to obtain a citedness of 50%) when applying WoS for articles. Applying GS implies a shorter delay and much higher citedness for all document types. Statistical significant correlations were only found between WoS and GS and the two publication point systems in between, respectively. The study demonstrates how the nCPPI can be applied to institutions as evaluation tools supplementary to JCI in various combinations, in particular when institutions include humanistic and social science disciplines.  相似文献

This article describes a collaborative action research conducted by a lecturer and several primary school art teachers, who between 2001 and 2006 created the Visual Arts Education Web (‘iii web’) in Hong Kong. The creation of the ‘iii web’ was accomplished through research that employed questionnaires, focus group discussions and individual interviews. Teachers' perceptions of using websites in teaching were examined, art education websites from Hong Kong, Taiwan, Mainland China and the USA were compared, in order to create a website that could meet the needs of Hong Kong primary school art teachers. Inquiry‐based learning is one of the important teaching approaches that were introduced during the Hong Kong Education Reform in 2003. An example of using the ‘iii web’ to teach public art is described to illustrate how the teacher and students used inquiry‐based learning in art education.  相似文献

School playgrounds offer everyday opportunities for physically active and social play that combats obesity, develops skills, and promotes well‐being. However, teachers’ fear of the legal consequences of injury can elicit over‐zealous risk reduction with the result that playgrounds lack challenge, and the potential benefits of play become limited. In this research, we trialled a simple, cost‐effective strategy to encourage children to be more active and social on a school playground. Over 11 weeks, we made available materials with no fixed purpose (e.g. car tires, boxes) to a playground of children aged five to seven. Accelerometers showed children became significantly more active. Interviews with teachers suggested children also became more social, creative, and resilient. However, despite no incidence of injuries, teachers perceived an increased risk and encountered dilemmas regarding duty of care. We conclude that future interventions should address issues of ‘surplus safety’ at individual, school, system, and policy levels.  相似文献
