To examine the reproducibility of three measurement techniques used to determine creatine kinase, interleukin-6 and high-sensitivity C-reactive protein, 50 participants had blood samples taken on two occasions. Fingertip plasma samples were analysed using the Reflotron for CK determination. Venous blood samples collected into serum separator tubes were used for IL-6 and hs-CRP analyses. IL-6 was measured using an enzyme linked immune assay development kit. The hs-CRP was measured by an in-house ELISA method. Dependent t-tests showed no systematic bias between samples. The interdian CV was 20.0% for CK, 15.3% for IL-6 and 44.2% for hs-CRP. The intraclass correlation coefficient was 0.90 for CK, 0.98 for IL-6 and 0.70 for hs-CRP. The 95% limits of agreement were ?69.7 to 63.5 IU/L for CK, ?1.48 to 1.80 pg/ml for IL-6 and ?1.10 to 0.91 µg/L for hs-CRP. The results demonstrate low absolute reproducibility, which may obscure a true experimental effect. 相似文献

Aiming to explore factors affecting Malaysian Chinese parents in sending their children to either national secondary schools or Chinese independent schools, 494 parents were surveyed using a questionnaire. Results showed that parents who sent their children to Chinese independent schools have different priorities compared to those who sent theirs to national secondary schools—the former are concerned with teachers’ quality, chances of learning the Chinese culture and Mandarin while the latter are concerned with tuition fees and strategic location. In general, the finding that Malaysian Chinese parents take cultural and language factors into account when choosing a suitable school for their children is interesting because both are seldom listed as important. 相似文献

The convergence of digital communications technologies is changing the nature of the relationships between post-secondary institutions, their students, and the private sector. The current predictable and ordered world of inter-institutional relationships is breaking down, to be replaced by one of perpetual change. Contemporary relationships can be modeled using Christaller's central place theory. On the other hand, we must turn to chaos theory for clues as to how institutions will be operating in an environment characterised by complexity and constant flux. 相似文献

This article presents research evidence concerning the introduction of performance appraisal in UK universities. The notion of ‘procedural compliance’ is proposed to draw attention to the implications of the largely externally imposed nature of appraisal in universities. The article reports the findings deriving from a study of appraisal in four universities. The notion of procedural compliance usefully illuminates the reactions of respondents to appraisal, though it has to be supplemented in order to provide a more complete picture. 相似文献

We designed and constructed a sundial for the purpose of observing the declination of the sun and thus marking solar seasonal variation. The 122 × 122 cm vertical sundial on the south-facing wall of our library has two unusual features: a nodus on the gnomon that casts a shadow of a point for marking the height of the sun and a large blank working space for students to mark the shadow of the nodus at different hours of the day and to connect the marks of 1 day in a line of declination. We discuss the design of a dial that emphasizes a working space for observations on solar declination, methods for determining the position of the nodus such that lines of declination can be observed every day of the year, mathematical procedures that minimize error in laying out the hour lines for this unusual design, the type of materials that are best suited for this design, and how students in an interdisciplinary honors colloquium on seasonal rhythms used the sundial. We also include two appendices on general sundial construction that indicates the information designers need to construct their own sundials. 相似文献

Validating performance standards is challenging and complex. Because of the difficulties associated with collecting evidence related to external criteria, validity arguments rely heavily on evidence related to internal criteria—especially evidence that expert judgments are internally consistent. Given its importance, it is somewhat surprising that evidence of this kind has rarely been published in the context of the widely used bookmark standard‐setting procedure. In this article we examined the effect of ordered item booklet difficulty on content experts’ bookmark judgments. If panelists make internally consistent judgments, their resultant cut scores should be unaffected by the difficulty of their respective booklets. This internal consistency was not observed: the results suggest that substantial systematic differences in the resultant cut scores can arise when the difficulty of the ordered item booklets varies. These findings raise questions about the ability of content experts to make the judgments required by the bookmark procedure. 相似文献
