Validation of self-report measures of physical activity: a case study using the New Zealand Physical Activity Questionnaire     

Mackay LM  Schofield GM  Schluter PJ 《Research quarterly for exercise and sport》2007,78(3):189-196

Accurate measurement of physical activity is fundamentally important in epidemiological research of physical activity behavior A widely used telephone-based physical activity questionnaire was compared with other methods of administration and objective measures (pedometers and accelerometers) among 80 adults (43 women). The telephone questionnaire was comparable to both the self-administered form and international telephone-administered equivalent. Although moderate correlation coefficients with objective measures supported the use of the questionnaire, wide prediction intervals generated using Bland Altman methods highlighted large discrepancies between the measures, particularly in the moderate intensity category. These findings illustrate the limitations of correlation coefficients in validation studies and the inaccuracy of self-report questionnaires in measuring physical activity.  相似文献   

Hyperhomocysteinemia,MMPs and Cochlear Function: A Short Review     

Seema Bhargava  Meghaa Shanta Bhargava  Eishaan Kamta Bhargava  LM Srivastava 《Indian journal of clinical biochemistry : IJCB》2016,31(2):148-151

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   

Head injury secondary to suspected child maltreatment: results of a prospective Canadian national surveillance program     

Bennett S  Ward M  Moreau K  Fortin G  King J  Mackay M  Plint A 《Child abuse & neglect》2011,35(11):930-936

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

The Place of Personnel in Higher Education     

Lesley Mackay 《Higher Education Quarterly》1995,49(3):210-228

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

Response to the discipline review of teacher education in mathematics and science     

Dr David Symington  Professor Lindsay Mackay 《Research in Science Education》1993,23(1):286-292

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. Specializations: science education, teacher education. Specializations: international education, educational measurement, science education.  相似文献   

Computer-supported aids to making sense of scientific articles: cognitive, motivational, and attitudinal effects     

Julie A. Gegner  Donald H. J. Mackay  Richard E. Mayer 《Educational technology research and development : ETR & D》2009,57(1):79-97

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.
