美国图书馆协会的<职业道德规范声明>提出了以图书馆事业为中心的具体原则,其<图书馆权利法案>则明确了图书馆的责任和义务.目前,美国社会和政治环境的变化为图书馆职业带来了越来越多的忧虑和压力."9·11"后出台的<爱国者法案>明显与图书馆职业道德规范中所阐述的重要原则相冲突.因此,美国图书馆协会决心抵制<爱国者法案>对知识、信息自由开放以及行使个人隐私权的限制. 相似文献

Extensive use of social networking sites by students and teachers makes educators and researchers to think whether they can be incorporated in instructional process to facilitate students’ learning. This survey-based study records and examines Pakistani pre-service teachers’ and teacher-educators’ current uses of Facebook, and their attitudes toward using Facebook for collaborative learning, and to see if there is a significant relationship between participants’ intensity of Facebook use and their attitude toward instructional use of Facebook. Results of the study indicated that pre-service teachers’ and teacher-educators’ motives for their current Facebook use are mainly limited for social purposes. Pre-service teachers’ use of Facebook is more intensified than the use of Facebook by teacher-educators. Further, pre-service teachers showed more positive attitudes toward using Facebook for collaborative learning than the attitudes of their faculty. Findings also indicated a positive relationship between participants’ Facebook intensity and their attitudes toward its use for collaborative learning. 相似文献

Literature on Web 2.0 experiences of higher education faculty in developing countries such as Pakistan is very limited. An insight on awareness and practices of higher education faculty with these tools can be helpful to map strategies and plan of action for adopting latest technologies to support teaching–learning processes in higher education of such countries. This survey study was aimed to examine the competence and practices of higher education faculty in Pakistan with Web 2.0 technologies such as blogs, Wikis, Google Docs, Skype, Flickr, YouTube, and social networks. The study was also focused to look for what type of role faculty play while using these tools; and to find whether any significant differences in terms of age, gender, or academic discipline exist in competence and usage of these tools by the faculty. The data were collected from a sample of 246 university teachers in the spring 2014 semester. The findings of the study indicated that faculty participants reported to use Web 2.0 social tools more frequently than instrumental tools. Similarly, their competence with social tools was higher than their competence with instrumental tools. Additional results indicated that their competence with Web2.0 tools significantly differed with respect to their age, gender, and academic disciplines. 相似文献

Seeds of a Chinese traditional medicine plant, Cochinchina momordica were used in the present study for the improvement of influenza vaccine （HSN 1） in chicken. Crude extraction from Cochinchina momordica seed （ECMS） was obtained by ethanol extraction method. In experiment No. 1, two weeks old chickens were immunized with influenza vaccine （HSN1） alone or combined with ECMS （5, 10, 20, 40 and 80 μg/dose）. Serum IgG antibody levels （by ELISA） as well as effects on dally weight gain were measured on 0, 7, 14 and 28th day after immunization. Results revealed that all ECMS groups numerically increased the antibody levels while 10 and 20 μg/dose groups significantly （P〈0.05） enhanced total IgG antibody on day 28, when compared with control. Average daily weight gain was also significantly higher in 20 μg/dose ECMS group. Adjuvant effect was also confirmed in experiment No. 2 when chickens were immunized with 20 μg/dose ECMS and antibody titer was measured through hemagglutination inhibition （HI）. It is concluded that ECMS has potential to improve the immune responses and deserve further study as an adjuvant. 相似文献

The phenomenon of “digital divide” is complex and multidimensional, extending beyond issues of physical access. The purpose of this study was to develop a scale to measure a range of factors related to digital divide among higher education faculty and to evaluate its reliability and validity. Faculty’s Information and Communication Technology Access (FICTA) scale was tested and validated with 322 faculty teaching in public and private sector universities. Principal components analysis with varimax rotation confirmed an 8-factor solution corresponding to various dimensions of ICT access. The 57-item FICTA scale demonstrated good psychometric properties and offers researchers a tool to examine faculty’s access to ICT at four levels – motivational, physical, skills, and usage access. 相似文献
