Acting diverse: target group orientation as key competence in engineering education

International companies are recognised by equity between men and women as well as between other different groups (Diversity) as an economic factor and incorporate it into their company visions. Mixed teams are set up to design target group-oriented products, for example in automotive engineering. Therefore they need employees who represent the different target groups, leading to a better integration of women and minority groups into their work force. The Managing Diversity approach is entering the German or European labour market via internationally working companies from the US, where Managing Diversity has been on the agenda for many years. At the same time, industry and universities in Germany face a huge problem: the lack of personnel in technical professions, especially the absence of women and of technically gifted, but not technically interested men. Additionally, during recent years, industry claims that the non-technical basic knowledge of graduates is very poor—and these are the competences that are important for successful cooperation processes. The current article will first describe the theoretical basis of teaching and learning diversity as a key competence and then show an example of implementing diversity and key competences in the traditional engineering curriculum.

老子的仁论及其理论意义

老子是第一个把“仁”纳入大道的范畴和大道联系起来思考的思想家。把“仁”纳入大道的范畴 ,这从本质上提升了“仁”的品格 ,从内涵上扩大了仁的人性表达 ,是真正意义上的仁论本体论思考 ;老子“仁”的本质特征乃自然无为 ,这是老子仁论思想的逻辑起点和必然归宿 ;老子仁论思想具有很强的理论指导意义 ,其思想奠定了中国仁学发展的基础 ,儒家仁学发展成了完整的思想体系 ,这与老子的仁论思想有直接的关系。     

跨国产学研合作的动力模型与案例分析

以国家为分析单元,研究提出跨国产学研合作的动力模型,包括政治动力、市场动力、研究动力和社会动力4个方面,以及地缘政治、市场因素、研发投资等14项因素.以中美清洁能源联合研究中心(CERC)为案例,对动力模型进行阐述和验证.案例分析显示,强大的合作动力可促成跨国产学研合作,动力不足时合作难以实现.最后,提出促进未来跨国产学研合作的五点建议,包括聚焦全球共同挑战、推动制度性开放、发挥非对称优势、强化人文交流纽带、政府与市场协作发力等.     

性出于气 有善有恶——王廷相的气质人性论

王廷相是明代中期气学的代表人物,他以元气为世界的本原,将理纳入气中,认为理为气之理,没有超越于气之外的理。在理气论的思想指导下,提出了性出于气,人物之性无非气质所为,离气不能言性,气质之性之外无本然之性;性出于气,有善有恶,人性可通过教化和习行而为善。

核心力量训练对高中生功能性运动能力影响的研究--以普定县第一中学为例

本文采用文献资料法、实验法等,探究核心力量训练对高中生功能性运动能力的影响。通过对对照组和实验组进行为期3个月的实验,实验组通过核心力量训练的介入,7个测试动作中,跨栏架步、直线弓箭步、稳定俯卧撑和旋转稳定性等动作模式质量得到显著提升,其他提升不显著,就整体而言,实验组学生的功能性运动能力得到提高;对照组学生的7个测试动作虽有提升,但提升不明显,就整体而言,对照组学生的功能性运动能力提高不明显。     

欧拉公式在电梯曳引力计算中的应用

曳引驱动电梯是由钢丝绳和曳引轮槽之间摩擦而产生曳引力来驱动轿厢作上下运动,钢丝绳对曳引轮的摩擦关系式符合欧拉公式。本文以欧拉公式为基础,推导出曳引力计算公式,并以实际电梯参数为例,计算出电梯在四种工作状况下的曳引力。     

Simultaneous measurement of back and front foot ground reaction forces during the same delivery stride of the fast-medium bowler

Six male cricket bowlers (mean - s x ¥ : age 23.5 - 1.3 years; height 1.83 - 0.04 m; body weight 826 - 20 N) performed their typical bowling action at a set of stumps positioned at standard pitch length (20.1 m). A specially designed force platform rig allowed the correct positioning of two force platforms to be achieved beneath an outdoor polyflex runway (0.017 m depth) for each player's delivery stride pattern. For the back foot, the peak vertical ground reaction force was 1.95 - 0.08 kN (2.37 - 0.14 BW) and the braking force was 0.77 - 0.12 kN (0.94 - 0.16 BW). For the front foot, the peak vertical force was 4.80 - 0.92 kN (5.75 - 0.98 BW) and the braking force was 2.93 - 0.56 kN (3.54 - 0.67 BW). The mean peak vertical loading rate for front foot contact was 205 - 52.8 kN·s -1 (249 - 64 BW·s -1 ) with mean values ranging from 81 to 446 kN·s -1 (98 to 540 BW·s-1). The range for back foot contact was much smaller, 25-70 kN·s -1 (30-85 BW·s -1 ), with a mean of 41.7 - 7.10 kN·s -1 (50.6 - 8.6 BW·s -1 ). Mean peak impact occurred 24 ms after touchdown for the back foot and 16 ms after touchdown for the front foot. At impact, mean peak loading rates were greater for the front foot at 246 kN·s -1 (298 BW·s -1 ), with a range of 80-483 kN·s -1 (98-534 BW·s -1 ), than for the back foot at 65 kN·s -1 (79 BW·s -1 ), with a range of 40-84 kN·s -1 (49-110 BW·s -1 ).
