New project system for undergraduate electronic engineering

A new approach to projects for undergraduate electronic engineering in an Australian university has been applied successfully for over 10 years. This approach has a number of projects running over three year period. Feedback from past graduates and their managers has confirmed that these projects train the students well, giving them the ability and confidence to work independently and collectively in the industrial world. Due to their importance to universities, staff and students alike, together with the potential heavy financial burden on the universities, careful planning has to be undertaken before implementing such projects. This paper presents some detailed suggestions on how such projects should be administered and operated as well as setting out possible criteria to assist supervisors in evaluating the final product from such projects.     

对湖南省开展龙狮运动的普通高校的调查研究

中国大学生体育协会龙狮分会正在大力倡导全国百校龙狮进课堂,在此前提下笔者调查发现,在湖南省普通高校中存在以下特点:开展龙狮运动的学校数量少,主要集中在设置了体育专业的普通高校;龙狮运动的参与者主要是体育专业的学生;主要参加"中国大学生体育协会龙狮分会"这一协会组织;主要以课程教学和运动训练的形式开展龙狮运动,其经费来源主要是学校拨款和进行有偿表演.

磷化铜/石墨烯锂离子负极材料的制备及其电化学性能研究

磷化铜由于其高理论容量和资源丰富等优点,逐渐成为一种拥有发展前景的新型锂离子电池负极材料.但其在充放电过程中存在着严重的体积膨胀和团聚问题,导致其循环性能差、倍率性能低.为此,我们利用水热法和低温磷化法合成了磷化铜/还原氧化石墨烯(Cu3P/rGO)复合材料,并对其物化特性和储锂性能进行了表征与测试.结果表明,rGO的修饰复合能够有效提高Cu3P的电化学性能,为发展新型锂离子电池负极材料提供实验与理论指导.     

试析美国大学学术职业发展的独特性——基于对美国大学终身教职制度的考察

虽然,美国大学学术职业起点甚低,但其成功性却是无与伦比的。终身教职制度作为美国大学的独创,对美国学术职业特色的形成起到了重要的作用。可以认为,美国大学学术职业的兴衰与终身教职制度的发展是休戚相关的。本文着重追溯了美国大学终身教职制度的产生过程,剖析了终身教职制度在当代所面临的困境和它所经历的变革。文章最后透过终身教职制度产生、变革与发展的历史,从更深层次上探讨了美国大学学术职业发展的独特性。     

试论当代学校固有职能的异化——学校教育对人的个性化发展的局限

一学校职能是指学校在社会分工中特有的专门职责。从逻辑层面分析,在当代社会条件下,“学校职能可分为个体个性化的职能与社会化的职能两类。前者是学校的固有职能,后者是学校派生的即工具的职能”。个体个性化职能是培养独立、健全、独特人格的职能,社会化职能是把个体培养成社会需要的能承担各种社会角色的职能。虽然从人的发展的角度来看,个性化和社会化是统一在完整的人身上的不同方面,甚至在某种程度上,社会化也是个性化的一部分,但如果一味强调社会化而忽视人的个性化,势必会导致个体独特人格的丧失和人的片面发展。逻辑层面上对学校…

Effects of astaxanthin on oxidative stress induced by Cu<Superscript>2+</Superscript> in prostate cells

Astaxanthin (AST), a carotenoid molecule extensively found in marine organisms and increasingly used as a dietary supplement, has been reported to have beneficial effects against oxidative stress. In the current paper, the effects of AST on viability of prostate cells were investigated by 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide (MTT) assay; cell apoptosis and intracellular reactive oxygen species (ROS) levels were determined by flow cytometry; the mitochondrial membrane potential (MMP) was measured by fluorospectrophotometer; and activities of malondialdehyde (MDA), superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GSH-Px) were evaluated by a detection kit. The results show that copper ion (Cu²⁺) induced apoptosis, along with the accumulation of intracellular ROS and MDA, in both prostate cell lines (RWPE-1 and PC-3). AST treatments could decrease the MDA levels, increase MMP, and keep ROS stable in RWPE-1 cell line. An addition of AST decreased the SOD, GSH-Px, and CAT activities in PC-3 cell line treated with Cu²⁺, but had a contrary reaction in RWPE-1 cell lines. In conclusion, AST could contribute to protecting RWPE-1 cells against Cu²⁺-induced injuries but could cause damage to the antioxidant enzyme system in PC-3 cells.
