西方的旧货市场,又称跳蚤市场,在那里一逛二逛,往往就能发现便宜又实用的物件。没准还能找到稀世珍宝呢。一个炎炎的夏日周末,Brad和妻子去旧货市场上逛了一圈,还真买到了个宝贝:一盏新灯具。这灯具买得是物美又价廉。但买回去后却导致了其他几笔不小的支出。这是为何?但听Brad细细道来。  相似文献

I have been told that in China, having a pet, particularly a dog, is often considered to be a status symbol because it shows the family can afford to have an animal. It is very different here.  相似文献

The paper experiments with, and reflects on, the limited possibilities for collaboration and communication across disparate groups within the university setting. The authors respond to the strong imperative to bring management, academics and support staff together, and so move beyond the entrenched positions and interests that those groups often display. They highlight the implications that this may have for collaborative academic publication. The text of the paper works as a research exercise in which each author's contribution constitutes data as well as providing reflections upon their own distinct identity and its consequences for communication in universities. The authors argue that attempts to enact ‘better communication’ is in many senses a failed project, but that it is this very fact which makes the experiment instructive. They conclude that calls to collaboration must acknowledge the fact that such relationships will always be relations of power, and are therefore not easily negotiated or understood.  相似文献

The purpose of this paper was to systematically review the current literature and elucidate the effects of total weekly resistance training (RT) volume on changes in measures of muscle mass via meta-regression. The final analysis comprised 34 treatment groups from 15 studies. Outcomes for weekly sets as a continuous variable showed a significant effect of volume on changes in muscle size (P = 0.002). Each additional set was associated with an increase in effect size (ES) of 0.023 corresponding to an increase in the percentage gain by 0.37%. Outcomes for weekly sets categorised as lower or higher within each study showed a significant effect of volume on changes in muscle size (P = 0.03); the ES difference between higher and lower volumes was 0.241, which equated to a percentage gain difference of 3.9%. Outcomes for weekly sets as a three-level categorical variable (<5, 5–9 and 10+ per muscle) showed a trend for an effect of weekly sets (P = 0.074). The findings indicate a graded dose-response relationship whereby increases in RT volume produce greater gains in muscle hypertrophy.  相似文献

There is a need for reliable analysis techniques for kinetic data for coaches and sport scientists who employ athlete monitoring practices. The purpose of the study was: (1) to determine intra- and inter-rater reliability within a manual-based kinetic analysis program; and (2) to determine test-retest reliability of an algorithm-based kinetic analysis program. Five independent raters used a manual analysis program to analyse 100 isometric mid-thigh pull (IMTP) trials obtained from previously collected data. Each trial was analysed three times. The same IMTP trials were analysed using an algorithm-based analysis software. Variables measured were peak force, rate of force development from 0 to 50 ms (RFD50) and RFD from 0 to 200 ms (RFD200). Intraclass correlation coefficients (ICC) and coefficient of variation (CV) were used to assess intra- and inter-rater reliability. Nearly perfect reliability was observed for the manual-based (ICC > 0.92). However, poor intra- and inter-rater CV was observed for RFD (CV > 16.25% and CV > 32.27%, respectively). The algorithm-based method resulted in perfect reliability in all measurements (ICC = 1.0, CV = 0%). While manual methods of kinetic analysis may provide sufficient reliability, the perfect reliability observed within the algorithm-based method in the current study suggest it is a superior method for use in athlete monitoring programs.  相似文献
