河南省高等职业教育已进入快速发展时期,高等职业教育资源主要在三方面共享,即校内资源共享、校际资源共享以及学校与社会资源共享。但在资源共享方面存在着生源不足,企业参与的积极性不够高,共享收益分配不明晰等问题。建议政府建立和完善有利于高职教育资源共享的制度,形成有利于高等职业教育资源共享的外部环境,职教集团也需进一步完善有关规章制度。 相似文献

Aiming at exploring the excellent structural performance of the vein-stiffening membrane structure of dragonfly hind wings, we analyzed two planar computational models and three 3D computational models with cambered corrugation based on the finite element method. It is shown that the vein size in different zones is proportional to the magnitude of the vein internal force when the wing structure is subjected to uniform out-of-plane transverse loading. The membrane contributes little to the flexural stiffness of the planar wing models, while exerting an immense impact upon the stiffness of the 3D wing models with cambered corrugation. If a lumped mass of 10% of the wing is fixed on the leading edge close to the wing tip, the wing fundamental fre- quency decreases by 10.7%-13.2%; if a lumped mass is connected to the wing via multiple springs, the wing fundamental frequency decreases by 16.0%-18.0%. Such decrease in fundamental frequency explains the special function of the wing pterostigma in alleviating the wing quivering effect. These particular features of dragonfly wings can be mimicked in the design of new-style reticulately stiffening thin-walled roof systems and flapping wings in novel intelligent aerial vehicles. 相似文献

Research has examined the relationship between traditional news media use and normatively important political outcomes such as knowledge and participation. However, most research fails to account for variations in the nature of news over time and across communities that could alter the fundamental relationship between exposure and these outcomes. Here two studies are presented—one with variation in news characteristics over time based on the American National Election Studies time series data and another with variation across local communities and newspapers within a single state during a single election year—to assess the hypothesis that the relationship between news use and political outcomes are moderated by natural variations in the nature of the news content and news outlets. 相似文献

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. 相似文献
