This paper examines in detail one aspect of the eLib funded BUILDER hybrid library project ‐ the impact of the BUILDER Project on strategic management within the University of Birmingham. Data was collected from senior managers at the outset and end of the Project to explore their changing views on the concept of the hybrid library and its development, and to identify the extent to which the BUILDER Project had influenced their thinking. Although BUILDER was considered to be having an impact on many Schools, social, political and technological developments in the wider arena were having the most impact. It was acknowledged that the services and technologies developed through the Project would be valuable in supporting the transition towards a hybrid environment, and had worked consistently to do this. The paper sets this data within the broader context of factors influencing change in university strategic management over the past five years. 相似文献

Laboratory science classes offered to students learning at a distance require a methodology that allows for the completion of tactile activities. Literature describes three different methods of solving the distance laboratory dilemma: kit-based laboratory experience, computer-based laboratory experience, and campus-based laboratory experience, which all allow the implementation of laboratory activities to students learning science at a distance. This article describes an additional method of implementing laboratory activities using interactive television. Interactive television allows real-time, synchronous student–instructor communication and interaction. 相似文献

This paper reports on a longitudinal study of developments in use of the Internet by science student‐teachers on Post Graduate Certificate of Education (PGCE) courses in five higher education institution–school partnerships in England. These are 1‐year, full‐time, teacher training courses for graduate scientists. The aim of the research was to examine changes in attitudes to, and use of, the Internet to support science teaching and the perceived challenges and barriers to practice in schools, against a background of high national expectations reflected in the qualification standards of the teacher education courses. The research has involved nearly 600 student‐teachers, representing between 7% and 8% of those training on PGCE science courses in England, and has employed mixed methods, with questionnaires serving as the main basis for analysing trends, and focus groups and case studies used to gain deeper insight to the particular issues identified. The process has been an iterative one, with the outcomes of each year’s research being used to inform further research and course developments in the institutions involved. The findings indicate that attitudes and confidence in use of the Internet have improved over the period, with evidence of increased application directly in the classroom. However, in addition to some of the generic technological issues that may hinder developments in the use of Information and Communication Technology in schools, there are continuing concerns relating to limited pedagogical guidance and availability of good role models. The implications of this for developments in science teacher education programmes are discussed. 相似文献

This paper reports on part of an ongoing research project in England concerning the Nature of Science (NOS). The particular focus is on the initial thinking of the graduate scientists starting a one-year, Postgraduate Certificate of Education (PGCE) course and the way the course approaches adopted influence their views and understanding of NOS and their teaching. The research is set against a wealth of literature indicating that teachers find it difficult to teach curricula that emphasise NOS. Thus a key impetus for research in this area has been to look for ways that beginning teachers might be better prepared to face such challenges. Sample The paper draws on data from three cohorts of secondary PGCE students in a university–schools partnership, involving a total of 169 students. Design and method The research lies within a design research tradition. It has used mixed methods, involving written tasks, interviews and focus groups, with an iterative approach where the outcomes from one cohort have been used to inform course developments in successive years. Results The results from these cohorts suggest that, while the students starting the course have a less restricted view of NOS than indicated by some other studies, in most cases there is a lack of breadth and depth to their understanding. There is some evidence that the use of specific tasks focusing on NOS in university-based sessions may be helping to develop and deepen understanding. However, the impact of current approaches remains fairly limited and attempts to develop teaching practices often face considerable barriers in the school-based practicum. Conclusions Graduate science students’ understanding of NOS as they embark on the PGCE is not highly developed. Hence, the emphasis on aspects of NOS in the school curriculum presents a considerable challenge. This study suggests that there is a need to both further develop an explicit focus on NOS in university-based sessions and to develop closer relationships between schools and university faculty in seeking to support developments in classroom practice in this difficult area. 相似文献

The organizers of this conference have given me a difficult task: that of finding heretofore unfound implications of Whitehead's philosophy for environmental thought. The task is not difficult because implications of Whitehead's philosophy for environmental thought are hard to find. They are easy to find. The problem is that so many people have found them that finding something new to say is not easy.In what follows, however, some new implications are actually ferreted out. They fall under three headings: a) the interrelations between three ways of thinking about the environment: bioregionalism, land ethics, and the philosophy of organism; b) the implications of Whitehead's philosophy of organism for environmental aesthetics; and c) the implications of Whitehead's philosophy of organism for human communities (sustainable communities) viewed as interfused with living nature. 相似文献

Trichloroacetic acid (TCA) solubilized and DEAE fractionatedMycobacterium tuberculosis H37Ra excretory-secretory (ES) antigen viz., Mtb EST DE1 and affinity purified goat antibodies to the TCA solubilized ES antigen
(Mtb EST) were explored in detecting tubercular antibody and antigen respectively in sera of bone and joint tuberculosis by
indirect and sandwich ELISA. Out of total 36 bone & joint tuberculosis cases, tubercular antibody was detected by indirect
ELISA in 30 patients (sensitivity 83%), while circulating tubercular antigen was detected by sandwich ELISA in 27 patients
(sensitivity 75%). Out of 34 non tubercular disease control cases, 10 patients showed positive reaction for antibody while
only 4 patients showed positive reaction for antigen. In another group of 34 healthy subjects who were screened, 4 individuals
showed positive reaction for tubercular antibody and 2 cases for antigen. This study shows that antigen detection assay using
affinity purified anti Mtb EST antigen antibody is superior with overall specificity of 91% as compared to antibody detection
assay with 75% specificity in bone & joint tuberculosis. 相似文献

Oxidative stress was studied by estimating plasma levels of malondialdehyde (MDA), beta carotene, vitamin E and erythrocytic
superoxide dismutase(E-SOD) activity in 50 cases of carcinoma of upper digestive tract which included carcinoma of oral cavity,
pharynx and oesophagus. While plasma MDA level was found to be increased (3.5±1.0 nmole/ml), a significant decrease in beta
carotene (81.2±14.5mg%), vitamin E (8.5±1.1 mg/L) level and E-SOD activity (657.0±80.6 U/G Hb) were observed in carcinoma
of upper digestive tract. Patients were treated with radiotherapy which itself was toxic enough and produced its deleterious
effects by generation of reactive oxygen species (ROS). As antioxdiants can detoxify ROS, beneficial effect if any, of antioxidant
administration during radiotherapy was studied in two groups of patients, group A (n=5, supplemented with antioxidants) and
group B (n=5, without antioxidant supplementation). Plasma MDA level was found to be elevated in both the groups but the increase
in group B was significant, compared to pretreatment level. Further, body weight was found to be significantly decreased in
group B patients, which was maintained in group A patients. Moreover, group A patients showed significant elevation in beta
carotene concentration, thus showing beneficial effect of administration of antioxidants during radiotherapy without disturbing
the desirable therapeutic effect of radiotherapy. 相似文献

Necessary and sufficient conditions are obtained for the realization of an m-variable positive real function (PRF) as the impedence function of a resistively-terminated ladder network of m lossless two-ports connected in cascade. Each two-port is a single-variable lossless ladder with all of its transmission zeros either at the origin or at finity. Conditions are also obtained when each of the two-ports is a Fujisawa-type lowpass ladder. 相似文献

This study examined 191 high school students’ willingness to recite the Pledge of Allegiance, their reasons for participating or not participating in saying the Pledge, and their thoughts about the Pledge during this daily school ritual. The study was conducted in a rural town next to the Akwesasne Mohawk reservation. The majority of the students chose not to recite the Pledge, and Mohawk students were less likely to recite the Pledge than their classmates. 相似文献
