Media Literacy Art Education: Deconstructing Lesbian and Gay Stereotypes in the Media

Popular media such as films, television programmes/commercials and magazines have become the dominant source through which children learn about others and their world, develop attitudes and beliefs as manifested in media expressions, and formulate their sense of identity. Popular media have enormous influence on children who are constantly immersing themselves in value‐laden media images that perpetuate over‐generalised representations of cultural groups, in particular, lesbian and gay stereotypes. By critically examining media images in the art room, media literacy art education offers art teachers and their students an opportunity to nurture their aesthetic sensibilities, social awareness and the media literacy necessary to resist and challenge prejudiced, dehumanised or unjust social practices. This article explores issues of lesbian and gay stereotypes in the media, and proposes using media images as a pedagogical device to help students deconstruct them.     

关于推进黄石市企业上市问题的研究

经济发达程度与企业上市状况是互为因果的正相关关系。当前在要素瓶颈制约突出的形势下,进一步推进企业上市,尽快培育一批有影响、有规模的优质企业进入证券市场,不失为做大做强黄石工业经济的一条重要途径。文章围绕我市企业上市存在的问题、原因进行分析,提出了自己的一些思考和建议。     

科学定位 教研并重 加强电大开放教育内涵发展

电大开放教育发展的十年发展已完成了第一步硬件建设与规范建设的历史使命,自然转向“内涵建设”的第二步。“内涵发展、刻不容缓”。已成为电大人的共识,但内涵发展的当务之急是什么,从何处着手,如何考核将是我们面对的新课题,这也是本文的立意。     

区域公共图书馆与高校图书馆协同发展构想

公共图书馆与高校图书馆是我国城市中两种最主要的图书馆类型。由于体制及观念等的限制,目前区域公共图书馆与高校图书馆的协同发展只能采取以公共图书馆为主干,以高校图书馆为旁支的服务主导型协同模式。论文阐述了公共图书馆与高校图书馆协同发展的基础、障碍、基本设想和保障机制。     

Design and integration of an all-in-one biomicrofluidic chip

We demonstrate a highly integrated microfluidic chip with the function of DNA amplification. The integrated chip combines giant electrorheological-fluid actuated micromixer and micropump with a microheater array, all formed using soft lithography. Internal functional components are based on polydimethylsiloxane (PDMS) and silver∕carbon black-PDMS composites. The system has the advantages of small size with a high degree of integration, high polymerase chain reaction efficiency, digital control and simple fabrication at low cost. This integration approach shows promise for a broad range of applications in chemical synthesis and biological sensing∕analysis, as different components can be combined to target desired functionalities, with flexible designs of different microchips easily realizable through soft lithography.     

Olivine-norite rock detected by the lunar rover Yutu-2 likely crystallized from the SPA-impact melt pool

Chang’E-4 landed in the South Pole-Aitken (SPA) basin, providing a unique chance to probe the composition of the lunar interior. Its landing site is located on ejecta strips in Von Kármán crater that possibly originate from the neighboring Finsen crater. A surface rock and the lunar regolith at 10 sites along the rover Yutu-2 track were measured by the onboard Visible and Near-Infrared Imaging Spectrometer in the first three lunar days of mission operations. In situ spectra of the regolith have peak band positions at 1 and 2 μm, similar to the spectral data of Finsen ejecta from the Moon Mineralogy Mapper, which confirms that the regolith''s composition of the landing area is mostly similar to that of Finsen ejecta. The rock spectrum shows similar band peak positions, but stronger absorptions, suggesting relatively fresh exposure. The rock may consist of 38.1 ± 5.4% low-Ca pyroxene, 13.9 ± 5.1% olivine and 48.0 ± 3.1% plagioclase, referred to as olivine-norite. The plagioclase-abundant and olivine-poor modal composition of the rock is inconsistent with the origin of the mantle, but representative of the lunar lower crust. Alternatively, the rock crystallized from the impact-derived melt pool formed by the SPA-impact event via mixing the lunar crust and mantle materials. This scenario is consistent with fast-cooling thermal conditions of a shallow melt pool, indicated by the fine to medium-sized texture (<3 mm) of the rock and the SPA-impact melting model [Icarus 2012; 220: 730–43].     

溴乙烷的水解和消去反应对比实验改进研究

卤代烃的水解和消去反应是高中化学教材选修五有机化学的重要反应。改进实验以溴乙烷为例,针对教材演示实验现象不明显、耗时较长等不足,设计溴乙烷水解和消去反应的对比实验,巧妙将溴乙烷的水解反应产物乙醇收集后用于作为消去反应的反应物。改进后的实验反应速率快、实验现象明显、操作方便,可在同一连续反应的装置中熟悉和掌握水解和消去反应的区别与联系,以及两者反应条件和产物的差异,有助于提高学生"宏观辨识与微观探析"的化学核心素养。     

女大学生体育运动态度的调查研究

从态度的三个层面：认知层面、情感层面、行为层面对师专女大学生体育运动的态度进行研究分析．结果表明，就整体而言师专女大学生对体育运动的认识处于较低水平．她们特别重视自身参加锻炼的情感体验，对体育运动的行为倾向处于一般水平，     

"滋味说"的肯定与否定——兼论中国古代诗学研究古今言说路径的差异及应对方式

钟嵘《诗品》的“滋味说”是中国诗学研究中较为重要的理论成说。近年来，有关其说的存无，争议较大。事实上，存、无两派的争论，言各有当，亦言各有失。两派的争议根基于中国古代诗学研究古今言说路径的差异及不同的应对方式。通过对存、无两派争议的梳理，可以管窥中国古代诗学研究中古今言说路径的差异及其原因。古今诗学言说路径的差异不可能通过一方否定另一方的办法得到合理的解决，他们只能通过打通差异的办法得到较好的转化，此即古代诗学研究中的求异取通之法。
