从高校德育看当代大学生社会责任感的培养

随着市场经济的深入发展和多元价值的广泛影响,当代大学生社会责任感缺失的问题日益凸显。高校作为培养大学生成才的主要阵地,担负着培养大学生社会责任的主要工作。从高校现状来看,存在着一些不足。因此,要进一步完善高校思想政治教育工作,提出切实可行的措施来提高大学生社会责任感。

Ecological Mural as Community Reconnection

Murals are particularly visually captivating forms of public art due to their size and accessibility. Mural images also capture public attention and provoke viewers to explore layers of meaning and find hidden stories. They are often in places that people come to visit, study, play, congregate and discuss matters that may relate to the content of the mural. To this end, murals can be effective tools for helping communities think about their environmental issues. This article discusses the Mystic River mural project in Somerville, Massachusetts, USA. It addresses how the local art councils, mural artists, local students, community members and non‐profit organisations collaborated to carry out this ongoing mural project. The purpose of this research is to examine how Mystic River eco‐murals were created, what challenges and benefits the eco‐murals provided, how local social concerns were represented through the eco‐murals, how eco‐murals can continue to promote environmental awareness and inspire youth about their community and the local environment, and how the mural can continue to reflect or affect the meaning of the place. This process can serve as an example for other communities that seek to address their environmental concerns through public art.     

大学生印象整饰与人际信任的相关性研究

以徐州师范大学340名大学生为被试,使用Snyder的自我监控量表个人反应问卷和人际信任量表(ITS)作为研究工具,探讨大学生印象整饰与人际信任之间的关系,结果显示:1.不同性别的大学生在自我监控总分上差异不显著;2.不同年级大学生在自我监控总分上的差异不显著;3.不同生源地区大学生在自我监控总分上差异显著,来自城市的大学生自我监控总分明显高于来自农村的大学生;4.大学生印象整饰水平与人际信任水平不存在显著相关。     

如何提高研究生创新能力与教育质量——基于研究生暑期学校建设绩效实证研究

随着国际政治、经济、文化竞争的加剧,高等教育已成为增强国家实力和国际竞争力的重要方面。在我国实施的“科教兴国”、“人才强国”、“建设创新型国家”等一系列重大战略中,大学作为国家创新体系的组成部分,承担着培养拔尖创新型人才的重任,因此,需要主动适应社会经济发展需要,更新教育观念,完善创新管理机制,努力探索培养创新型人才的模式和途径,积极推进研究生创新教育,提升研究生创新能力、科研水平与教育质量。

Simple Preparation of Spherical Activated Carbon with Mesoporous Structure from Phenolic Resol and Associated Catalytic Performance in Isobutane Dehydrogenation

This study provides a detailed report on the synthesis of spherical activated carbon with mesoporous structure using a soluble low molecular weight phenolic resol precursor through an ammonium alginate assisted sol–gel method. The effects of calcinating temperature and the addition of CaCO_3 as a pore-enlarging agent on texture structure and catalytic performance in isobutane dehydrogenation to isobutene were investigated. Characterization of N_2 sorption,mechanical strength tests,and optical photographs confirmed that the obtained carbon materials had high mechanical strength,a good degree of sphericity,and a large surface area. Introducing CaCO_3 as a pore-enlarging agent during the preparation process promoted the formation of a mesoporous structure of carbon spheres and evidently increased the surface area and oxygen content,which can improve isobutane conversion and isobutene selectivity of these carbon spheres. The conversion of isobutane reached up to 28% for this spherical activated carbon,and the selectivity of isobutene reached up to 96%. Isobutane conversion increased with an increase in calcination temperature due to an increase in the oxygen content,whereas the selectivity of isobutene decreased due to the slight decrease in the specific surface area.
