不同土壤条件对曼地亚红豆杉抗寒性影响研究     

芦站根 《衡水学院学报》2008,10(1):63-66

以不同土壤(酸壤和碱壤)条件下3年生曼地亚红豆杉为材料,用生理生化方法从低温半致死温度(LT50)、自由水和束缚水含量2项生理指标研究了曼地亚红豆杉在自然降温过程中抗寒力的变化,所得各项结果分别为:(1)不同土壤条件的曼地亚红豆杉低温半致死温度在自然降温过程中均随着气温的降低而降低,且与采样前半月平均最低温度呈线性相关,在整个变化过程中,二者的低温半致死温度均表现为:酸性土壤小于碱性土壤.(2)酸性土壤条件下束缚水含量和束缚水与自由水比值均明显高于碱性土壤条件下.最后确定了曼地亚红豆杉抗寒性大小为:酸性土壤强于碱性土壤.  相似文献   

以错位竞争理念构想地市级电视媒介产业发展战略     

樊昌志  申芳龄 《湖南城市学院学报》2003,24(4):8-12

错位竞争以取得市场利基(Niche)为目标。媒介产业的错位竞争，就是某一级的某一类媒介产业以取得自身可能占有的媒介资源为市场目标而采取的避免与竞争对手正面交锋的市场策略或理念。以错位竞争理念构想地市级电视媒介产业的发展战略，需要实现三个战略目标：选择合适的媒介生态位作为地市级电视媒介产业的生存与发展空间；定位“受众圈”作为地市级电视媒介产业的目标市场；开创著名的地方性电视媒介品牌。  相似文献

Librarians as Advocates of Social Media for Researchers: A Social Media Project Initiated by Linköping University Library,Sweden     

Sassa Persson  Maria Svenningsson 《New Review of Academic Librarianship》2016,22(2-3):304-314

ABSTRACT

Librarians at Linköping University help researchers keep abreast of developments in their fields and to increase the visibility of their work. Strategic, professional use of social media ought to be an essential part of a researcher's communication strategy. This article investigates the level of awareness of the professional use of social media among LiU researchers. The investigation showed that use of social media was not significant; however, a small number saw potential. The purpose of this article is threefold. The first purpose was to evaluate the potential of using social media as a tool for communicating research outside LiU. Second, the article presents a study in which views of LiU researchers on social media were ascertained via seminar discussions, informal feedback, and interviews. The study has a case study approach involving eight researchers. Third, the article covers how LiU Library created a web-based information package to support researchers in social media use.  相似文献   

Ugandan adolescents’ sources,interpretation and evaluation of sexual content in entertainment media programming     

Ann Neville Miller  Evangeline Nalugya  Charles Gabolya  Sarah Lagot  Richard Mulwanya  Joseph Kiva 《Sex education》2016,16(6):707-720

Although mounting evidence in Western nations indicates that entertainment media influence young people’s sexual socialisation, virtually no research has addressed the topic in sub-Saharan Africa. The present study employed 14 focus groups of Ugandan high school students to identify media through which they were exposed to sexual content, how they interpreted and evaluated that content, and how they compared its influence with that of parents, schools and religious institutions. Participants most often mentioned TV, followed by print media and Internet as sources of sexual material. Media were said to present discrepant messages regarding the timing of sexual debut, with international programming urging early sexual debut and local programming described as urging young people to delay sex. Young people spoke of turning to ssengas and kojjas for sexual advice, and a number of boys suggested pornography could also be educational. Both local and international programming was interpreted as conveying views of men as sex driven and women as submissive in sex and relationships. Participants expressed the belief that sexual media content had a negative impact on young people. Most nevertheless assessed these messages as more influential than other sources of sexual socialisation.  相似文献
