贫困生的心理辅导与构建和谐社会的关系     

张丽妮 《铜仁职业技术学院学报》2006,(4)

随着社会主义市场经济的逐步发展,我国普通高等学校招生、就业制度改革的逐步深化。另一方面,由于市场经济的运作过程中有些国有企业加大改革力度,下岗职工增多,以及农村经济发展滞后、不平衡等原因,高校贫困生迅速增多,并形成了一个特殊群体。贫困生问题日渐突出,这对和谐社会构建带来一定的负面影响。因此对贫困生进行良好的心理辅导,是构建和谐社会必不可少的一项工作。  相似文献

Effects of coffee and caffeine anhydrous on strength and sprint performance

Caffeine and coffee are widely used among active individuals to enhance performance. The purpose of the current study was to compare the effects of acute coffee (COF) and caffeine anhydrous (CAF) intake on strength and sprint performance. Fifty-four resistance-trained males completed strength testing, consisting of one-rep max (1RM) and repetitions to fatigue (RTF) at 80% of 1RM for leg press (LP) and bench press (BP). Participants then completed five, 10-second cycle ergometer sprints separated by one minute of rest. Peak power (PP) and total work (TW) were recorded for each sprint. At least 48 hours later, participants returned and ingested a beverage containing CAF (300?mg flat dose; yielding 3–5?mg/kg bodyweight), COF (8.9?g; 303?mg caffeine), or placebo (PLA; 3.8?g non-caloric flavouring) 30 minutes before testing. LP 1RM was improved more by COF than CAF (p?=?.04), but not PLA (p?=?.99). Significant interactions were not observed for BP 1RM, BP RTF, or LP RTF (p?>?.05). There were no sprint?×?treatment interactions for PP or TW (p?>?.05). 95% confidence intervals revealed a significant improvement in sprint 1 TW for CAF, but not COF or PLA. For PLA, significant reductions were observed in sprint 4 PP, sprint 2 TW, sprint 4 TW, and average TW; significant reductions were not observed with CAF or COF. Neither COF nor CAF improved strength outcomes more than PLA, while both groups attenuated sprint power reductions to a similar degree. Coffee and caffeine anhydrous may be considered suitable pre-exercise caffeine sources for high-intensity exercise.  相似文献   

Setting the Stage and Keeping Sane: Implementing ArchivesSpace at the University of Minnesota     

Lisa Calahan 《Journal Of Archival Organization》2016,13(3-4):114-126

As the University of Minnesota's Archives and Special Collections began the daunting task of migrating into ArchivesSpace over 5,000 finding aids from fifteen different units, a clearly defined workflow provided clarity and success. This article outlines how staff developed an implementation timeline and workflow, harnessed support from partners in IT, provided training, and what the benchmarks to success were. By sharing this well-documented and thought-out implementation workflow, it can provide guidance as others try to navigate the many moving parts of implementing new collection management technology.  相似文献

The effect of l-citrulline and watermelon juice supplementation on anaerobic and aerobic exercise performance     

Paul T. Cutrufello  Stephen J. Gadomski  Gerald S. Zavorsky 《Journal of sports sciences》2015,33(14):1459-1466

Citrulline has been proposed as an ergogenic aid, leading to an interest in watermelon given its high citrulline concentration. The aim of this study was to determine the effects of a single, pre-exercise dose of l-citrulline, watermelon juice, or a placebo on the total maximum number of repetitions completed over 5 sets, time to exhaustion, maximal oxygen consumption (VO₂max), anaerobic threshold, and flow-mediated vasodilation. A randomised double-blind within-participants study design was used to examine these effects among 22 participants (n = 11 males). Supplementation included either a 7.5% sucrose drink containing 6 g of l-citrulline, 710 mL of watermelon juice (~1.0 g citrulline), or a 7.5% sucrose placebo drink. Supplementation was administered 1 or 2 h before exercise testing to investigate a timing effect. There was no significant effect between the three supplements for the total number of repetitions, time to exhaustion, VO₂max, anaerobic threshold, or flow-mediated vasodilation. There was also no interaction observed relative to gender or supplement timing (P > 0.05). A single dose of l-citrulline or watermelon juice as a pre-exercise supplement appears to be ineffective in improving exercise performance; however, greater doses of l-citrulline have been shown to be safe and are currently left unexamined.  相似文献
