民办高校与普通高校大学生心理健康状况的比较

通过对普通高校与民办高校大学生的心理健康状况进行比较研究,结果发现:两类大学学生的心理健康状况在学校类型之间除人际关系与恐怖因子外都存在着显著差异(P<0.05),民办高校大学生心理健康状况优于普通高校,而学校类型与性别、城乡生源以及是否独生子女的交互差异都不显著。     

基于J2ME的教师个人信息助理软件

随着高校教师越来越多地同时从事教学、科研和行政等各方面工作,有必要对各类相关信息进行简单方便的管理查询。笔者利用手机携带方便的特点,在基于Java 2 Micro Edition(J2ME)规范的手机上研制了教师个人信息助理软件。该软件功能系结合高校实际情况而设计,解决了手机数据导入和更新的问题。经过在多种手机上使用,证明该软件可以正常使用,并有助于提高教师的工作效率。     

浅谈高校后勤改革中的与时俱进

在高等教育改革体系中,高校后勤改革已成为社会热点和高校改革工作的重点之一．高校后勤的改革必须从认识、服务、管理、环境等方面与时俱进,从实际出发,科学定位．

Mating behaviour and maternal care in the tropical savanna funnel-web spider Aglaoctenus lagotis Holmberg (Araneae: Lycosidae)

Despite their abundance and diversity, Neotropical spiders have been the subject of relatively few studies of behavioural ecology. The sexual behaviour and maternal care of the spider Aglaoctenus lagotis (Lycosidae) is described here. We performed experimental manipulations to test the hypothesis that males are attracted by female cues in the web. Two predictions were tested: (a) webs used by a virgin female will attract more males than webs used by an inseminated female; (b) the main cue in the web is chemical, so webs recently used by virgin females will attract more males than those that are not recently used. Additionally, we tested the hypothesis that maternal care increases offspring survivorship. Results showed that males are attracted by recently used webs (z = 0.0015; p = 0.037; z-test) and webs of virgin females (z = 0.041; p = 0.036, z-test). Male sexual behaviour presented three different categories: court, pre-mate and mate. After the mating, the females built a cocoon that was transported adhered to the spinnerets and held by the last pair of legs. After the hatching of the eggs, the young migrated to the dorsal region of the mother's body for 5 days. During maternal care the mother eliminates a yellowish drop from its oral cavity, which is collected by the young. During the development of the young until adulthood, the offspring that have their mother present in the first stages of life have greater survival compared with those without maternal care. Our results make it possible to perform comparative analyses between a South American Lycosidae species and other species distributed worldwide.     

Species of the genera Bakera and Mangganeura (Homoptera: Auchenorrhyncha: Typhlocybinae) occurring on mango and other crop plants in the Oriental region

The genera Bakera (Bakera), Bakera (Guinobata) and Mangganeura (Homoptera: Auchenorrhyncha: Typhlocybinae) are re-described and compared. Sandalla is considered a synonym of Bakera (Guinobata) (syn. nov.).

Bakera (Bakera) nigrobilineata (Melichar) (=vittata Mahmood) is redescribed and illustrated from mango in the Philippines, on which it is frequently abundant, and found in association with Bakera (Bakera) luzonica sp. nov. which is described. Bakera (Bakera) abaca sp. nov. is described from the Philippines having been collected on abaca (Manila hemp). Bakera (Guinobata) nigroscuta Mahmood is redescribed from the Philippines and its association with coconut confirmed. Mangganeura reticulata Ghauri, described from Malaysia on mango, has been found in Thailand and the hitherto unknown female is described.     

我国高校科研态势与科研体制改革对策

我国高校科研在全国科研体系中占有重要地位,同时在科研评价导向、协作机制、科研经费管理、大学功能与创新文化等方面存在不利于科研质量提升的问题。本文分析提出了为实现高校科技创新而应当采取的科研体制改革对策,主要包括：明晰高校新的功能定位;改进科研评价体系;加强高校内外的资源互补性合作;建立科研项目间接经费补偿机制;培育大学精神与创新文化。     

媒体负面报道对公司股价影响的研究:来自白酒塑化剂事件的证据

金融学理论认为,资本价格会因意外重要事件的冲击而发生变化.过去许多文献讨论过股票价格与媒体报道这一外部冲击之间是否存在显著关系,但是,这些研究所得结论并不尽一致.基于此,本文以白酒塑化剂事件为例,分析塑化剂曝光新闻数量对白酒公司股价的影响.研究表明,塑化剂曝光在较长时间内影响了白酒板块的股价,但是曝光事件对各个公司股价影响的程度不一.此外,研究还发现,中央反腐抑制了白酒板块的股价.     

基于SD-SEM模型的消费者食品安全风险感知的信息搜寻行为

本文利用系统动力学模型和结构方程模型来研究消费者食品安全风险感知和消费者信息搜寻行为之间的关系,在总结消费者食品安全风险感知和消费者食品安全信息搜寻行为研究文献的基础上,利用结构方程确定消费者食品安全风险感知的影响因素及其之间的路径系数,进而建立系统动力学模型模拟信息搜寻行为对消费者食品安全风险感知的影响,以提出降低消费者食品安全风险感知的建议.     

基于食品安全事件异质性的信息扩散过程研究

针对企业在食品安全事件中承担的责任不同,研究不同类型食品安全事件下的信息扩散过程,对政府和企业的食品安全应急管理和风险信息交流具有重要意义.本文首先构建了食品安全信息扩散的修正Bass模型,分析可辩解型食品安全事件下的负面信息扩散过程;然后,运用改进的社会影响模型分析了不可辩解型食品安全事件下的负面信息扩散过程;最后,运用顶新"馊水油"视频事件的互联网搜索数据进行实证分析.研究表明,可辩解型食品安全危机中的信息扩散达到动态稳定状态时,信任与不信任的消费者比例与正负信息的相互渗透率有关.在不可辩解型食品安全危机中,消费者对负面信息的免疫力越弱,越容易对食品企业和政府行为产生不信任,并改变消费决策,信息扩散速率和临界值的分布影响动态均衡的实现过程.
