Hyperhomocysteinemia (HHCY) has been demonstrated to affect cochlear microvasculature as well as cochlear epithelial cells directly, with a resultant alteration of the expression of matrix metalloproteinases (MMPs) and their inhibitors, tissue inhibitors of metalloproteinases (TIMPs). Hence, ascertaining the optimum concentration of MMPs and TIMPs in the cochlea could help to inhibit hearing loss due to HHCY by the administration of appropriate MMP inhibitors, Since infections/inflammations as well as ototoxic antibiotics have a similar mechanism of otic pathology, the cochlear damage they cause could also be similarly prevented. 相似文献

Objective
We sought to determine the incidence, clinical features, and demographic profile of head injury secondary to suspected child maltreatment (abuse or neglect) in Canada to help inform the development and evaluation of prevention programs for abusive head injuries.Methods
From March 1, 2005 to February 28, 2008, an average of 2,545 paediatricians and paediatric subspecialists were surveyed monthly through the established network of the Canadian Paediatric Surveillance Program. We calculated incidence rates using the number of confirmed cases over the product of the duration of the study (3 years) and population estimates by age group.Results
There were 220 confirmed cases of head injury from suspected child maltreatment. The annual incidence rate was 14.1 per 100,000 for children less than 1 year of age and 1.4 per 100,000 for those less than 15 years. Seventy three percent (141) of cases involved infants less than 12 months of age and 52% (100) of cases involved infants less than 6 months of age. Seventy-five percent (165) of cases presented to the emergency room. With regard to outcome, 12% (27) of cases resulted in death and 45% (75) of survivors had neurological sequelae at discharge. Thirty percent (67) of all cases, as well as 30% (8) of deaths were previously known to child welfare authorities.Conclusion
This study provides an estimate of the rate of head injury secondary to suspected child maltreatment in Canada. The young age and poor medical outcomes of those involved highlights the need for prevention efforts that are implemented early in life. Given that a significant percentage of injured infants and children were already known to child welfare authorities, the study also highlights the need to establish and evaluate additional preventive efforts for parents and caregivers already in the child welfare system. 相似文献4.

Based on research in universities in the North of England, this article reflects on the growing size and widening remit of the personnel function. Differences between the old and new universities are discussed together with the possible future roles of personnel within higher education. The author feels that it is unlikely, given personnel directors views of the way the personnel function is seen by Vice Chancellors and Pro-Vice-Chancellors in the older universities, that the personnel function will play a more influential role in the immediate future. Also, despite a greater role being played by the personnel function in the new universities, a seat at the'top table'has generally been denied. The author concludes that in such labour-intensive organizations as universities, the failure to empower the personnel function is somewhat shortsighted given the growing number of government policies directed towards the activities of academic staff. 相似文献

This paper relates to a study commissioned by the Department of Employment, Education and Training to evaluate the impact
of the Discipline Review of Teacher Education in Mathematics and Science. The major datagathering strategies employed in that
study have been to visit every higher education institution in Australia involved in teacher education to interview relevant
staff and to seek information by mail from other bodies to whom recommendations of the Review were addressed. This paper reports
a supplementary activity, the analysis of citations of the Report of the Discipline Review in the journal of the Australasian
Science Education Research Association,Research in Science Education. This research reveals that there has been relatively little critical analysis of the Review, somewhat surprising in the
light of its significance for science teacher education. Further the citations in the journal suggest that the Review Report
has struck a responsive chord with those involved in the science education of primary school teachers. Its impact on secondary
teacher education would appear to be less significant. This difference is explored in the context of professional education.

High school students can access original scientific research articles on the Internet, but may have trouble understanding
them. To address this problem of online literacy, the authors developed a computer-based prototype for guiding students’ comprehension
of scientific articles. High school students were asked to read an original scientific research article about the effects
of drug or alcohol abuse, which was presented on a computer screen either with computer-based comprehension aids or without
aids. The aids provided background text and animations including answers given by the article authors. Across two experiments
involving different schools and different research articles, the comprehension aids group performed better than the control
group on a comprehension test concerning the article (d = +0.79 in Experiment 1 and d = +0.82 in Experiment 2) and rated the content of article as less difficult to read (d = +0.96 in Experiment 1 and d = +0.69 in Experiment 2). In addition, the comprehension aids group reported more positive motivational beliefs than the
control group concerning understanding what scientists do (d = +0.51 in Experiment 1 and d = +0.56 in Experiment 2), appraising the article as worthwhile (d = +0.80 for Experiment 1 and d = +0.70 for Experiment 2), and being interested in reading another research article (d = +0.19 in Experiment 1 and d = +0.58 in Experiment 2). The groups did not differ on their attitudes concerning a career as a scientist or about alcohol
and drug abuse. Overall, computer-based comprehension aids can help guide students’ comprehension processes for an original
scientific research article, which in turn can improve their appreciation of what scientists do.

James Mackay 《Gender and education》2010,22(1):87-103
This article considers the relationship between gender and self‐efficacy in teacher trainees engaged in an electricity‐related design and construction task. Quantitative data (examination scores, task assessment, and questionnaire) and qualitative data (interviews and written student reflections) were collected. There is a gender bias in student teachers entering the University with more male than female students having done Science to grade 12 level. In addition, the continuing differential in standards of education in South African schools necessitated distinguishing those who had attended educationally advantaged from those who had attended educationally disadvantaged schools. In the examination, a test of theoretical knowledge, male students in each group outperformed female students. This we explain in terms of school background, gender responses from family members who regarded Science as a male domain, and the resulting lower self‐efficacy of female students. However, female students achieved as well as male students in the design and construction task. We argue that although males had better self‐efficacy levels than females at the outset, the hands‐on, individual nature of a task in a domain usually constructed as male led to female students developing increased levels of self‐efficacy, which ensured task performance matching that of the more knowledgeable male students. 相似文献
