Increasing concern about the release of potentially harmful chemicals into the environment has led to efforts to collect data on such chemicals with a view to identifying and minimising the associated hazards. The collection and storage of such data requires cooperation and communication (both national and international) between partners in a general environmental data network. A format is described for the exchange of data between these network partners. This format is of general applicability. It is shown that a hierarchical tree structure best describes the situation. Rules are derived to identify and process the nodes in the tree such that information is neither lost nor degraded upon transfer between the network partners.  相似文献

This paper describes a project undertaken with parents from an inner city primary school in Hartlepool, England. The main objectives of the project were to increase the self esteem of the parents, to give them an understanding of the pre-school curriculum and to enable them to develop their skills, knowledge and confidence to become involved in school life and to take ownership of their own children's education. The project focused around the production of a video to show nursery life in the school and this production was used as a vehicle to encourage the fulfilment of the objectives described above. The paper concludes by describing the successful outcomes of the project. Some of the outcomes were planned for, but we were equally delighted with the unexpected ones.  相似文献

Spatial ability (SA) is the cognitive capacity to understand and mentally manipulate concepts of objects, remembering relationships among their parts and those of their surroundings. Spatial ability provides a learning advantage in science and may be useful in anatomy and technical skills in health care. This study aimed to assess the relationship between SA and anatomy scores in first- and second-year medical students. The training sessions focused on the analysis of the spatial component of objects' structure and their interaction as applied to medicine; SA was tested using the Visualization of Rotation (ROT) test. The intervention group (n = 29) received training and their pre- and post-training scores for the SA tests were compared to a control group (n = 75). Both groups improved their mean scores in the follow-up SA test (P < 0.010). There was no significant difference in SA scores between the groups for either SA test (P = 0.31, P = 0.90). The SA scores for female students were significantly lower than for male students, both at baseline and follow-up (P < 0.010). Anatomy training and assessment were administered by the anatomy department of the medical school, and examination scores were not significantly different between the two groups post-intervention (P = 0.33). However, participants with scores in the bottom quartile for SA performed worse in the anatomy questions (P < 0.001). Spatial awareness training did not improve SA or anatomy scores; however, SA may identify students who may benefit from additional academic support.  相似文献

Objectives:

The research objectives were to (1) describe the current and future roles of hospital librarians and the challenges they face and (2) find evidence supporting the hypothesis that librarians are essential to hospitals in achieving the organizations'' mission-critical goals.

Method:

The authors used results from a previous research study that identified the five organizational mission-critical goals important to hospital administrators and then searched the literature and solicited examples from hospital librarians to describe the librarian''s role in helping hospitals achieve these goals.

Results:

The literature supports the hypothesis that hospital librarians play important roles in the success of the hospital. Librarians support quality clinical care, efficient and effective hospital operations, continuing education for staff, research and innovation, and patient, family, and community health information needs.

Conclusion:

Hospital librarians fulfill many mission-critical roles in today''s hospital, providing the right information at the right time in a variety of ways to enhance hospital and medical staff effectiveness, optimize patient care, improve patient outcomes, and increase patient and family satisfaction with the hospital and its services. Because hospital librarians and their services provide an excellent return on investment for the hospital and help the hospital keep its competitive edge, hospital staff should have access to the services of a professional librarian.

Highlights

  • A review of the literature supports the hypothesis that services of the professional librarian result in:
    • enhanced staff effectiveness,
    • optimized patient care,
    • improved patient outcomes, and
    • increased patient and family satisfaction with the hospital and its services.

Implications

  • Because hospital librarians and their services provide an excellent return on investment for the hospital and help the hospital keep its competitive edge, hospital staff should have access to the services of a professional librarian.

This study investigated variation in students’ behavioral engagement across mathematics classes in China and the United States. Student behavioral engagement was examined along with two aspects of the classroom (group size and teacher instructions given about classroom behavior). Video observational data were collected and coded over 1051 time intervals in 35-minute mathematics sessions in Chinese classrooms (n = 8) and comparable American classrooms (n = 7). Latent growth analyses revealed that overall, behavioral engagement declined over time, although the drop-off was dramatically sharper in American classrooms relative to Chinese classrooms. In addition, larger group size and the timing of teacher instructions (given before versus after the behavior) were significantly associated with increased engagement. This study revealed compelling cultural differences as well as patterns in student and teacher behaviors associated with students engaging in on-task behaviors in the classroom. Implications for ways to promote effective classroom behavior are discussed.  相似文献

This paper reflects upon student teachers' conceptions of inter-community relations and the preparation they receive to address issues of diversity and mutual understanding. The study in Northern Ireland is set against a backdrop of political, social and educational change, where a shared, peaceful future appears possible. Student teachers at a Catholic institution and a predominantly Protestant institution indicated a willingness to engage with issues concerning diversity and inter-community relations, despite having a limited knowledge of the concepts. However they also demonstrated clear views about the relevance and value of the preparation they received. The findings are evaluated using multicultural theory.  相似文献

ABSTRACT:  This paper presents the findings from a study of the admission arrangements for all secondary schools in England. We sketch the history of selection, answer questions about the scale and extent of selection by attainment or aptitude including an account of partially selective schools, consider the similarity and differences between selection by aptitude and by attainment and analyse some of the issues associated with both kinds of selection.  相似文献

Since their incorporation in 1993, further education (FE) colleges in England have been responsible for their own staffing and, faced with funding constraints as well as recruitment and retention targets, some have introduced a new category of staff referred to here as ‘learning support workers’ (LSWs). Though their employment conditions and specific duties vary considerably, LSWs' work often includes providing individual care for students. In this small‐scale study, using semi‐structured interviews, the perceptions of some teachers and LSWs about the nature of their relationships with each other and with students are investigated. The study is set broadly in the context of debates about the impact of public sector reform on FE colleges and teachers. A discourse analysis approach is adopted in discussion of the data. The authors conclude that although they are differently positioned in relation to traditional discourses of professionalism, both teachers and LSWs are perceived to be carrying out what Hochschild termed ‘emotional labour’. The contradictory nature of emotional labour is also highlighted. Some of the implications of employing a new group of workers in FE are discussed.  相似文献

For a number of years, Rebecca Luce‐Kapler and Dennis Sumara have been investigating the ways in which literary practices of close reading can help change how we think and how we remember. They have also considered how such practices might help make us more critical of normative representations of remembered experience. More recently, they have been joined by Claire Robson, who works with and investigates memoir writing. In 2009, Robson and Sumara were joined by their six older lesbian research participants at a conference held at the University of British Columbia entitled ‘Queerly Canadian: Changing Narratives’. The six women performed extracts from memoirs they had written as part of the research data and joined the researchers in offering theories and insights about the writing processes in which the group had engaged. That presentation and this paper represent the evolution of a two‐year collaboration between these researchers and the six women, who are listed as co‐authors on both the presentation and this paper.  相似文献
