贫困生的心理辅导与构建和谐社会的关系

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。     

直观教具在制图教学中的运用

机械制图是培养学生的空间想象能力。而空间想象能力的培养可以说是非常困难的 ,但如果能合理的运用直观教具 ,则可变困难为容易     

审美主体的发展对艺术叙事模式的影响

叙事是人类述说世界最重要的手段,随着时代的变迁、审美主体的进化、艺术观念的演进,叙事的模式也会随之发生变化。每当人类进入一新的阶段,占统治地位的叙事模式也会随之改变,并且各种叙事模式以其各自的特点反映着审美主体的发展、演变情况。     

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.     

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

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.     

浅谈高职高专英语视听说课程替代英语基础课程的可能性

随着中国经济的发展,和外国的合作越来越多,这就加大了对英语人才的需求。但是基础英语教学过于注重知识(尤其是语法知识)的传授,轻视语言能力的培养。导致了经过十多年的学习后,中国学生还是听不懂、说不出英语,不能适应我国经济建设和社会发展的需要。因此,英语必须调整课程与教学计划,以培养学生的交际能力为目的。这不仅得到了理论支持,甚至各方面的条件的成熟都将支持这一变革。     

蔡元培:我国早期电化教育的推动者

蔡元培先生是早期中国电化教育的实践引导者和学术领路人,中国历史上许多电化教育人物和事件都和他有密切联系。他重视媒体的社会教育功能,为中国电化教育搭起了"大电教"的框架;他选拔培养电教人才,创立中国教育电影协会,起草制定教育电影法规,为早期电化教育顺利开展奠定了基础;他积极倡导将电影等新媒体运用于科学考察与社会教育,为新媒体的应用树立了典范。

论身体写作的产生及表现

我们的身体不断地被传统、文化、知识等外在之物异化,当一切外在的理想、意义、价值都破灭之后,身体成了唯一的真实.身体的角度逐渐成为现代学术的切入点,体验、实践的入思方式与之有关,回到身体,回到存在,在身体的基础上才有意义的诞生.
