The number of educators, administrators, and institutions that utilize social networking has increased dramatically. Many have adopted social networking in order to be up-to-date and connected with their students’ learning beyond the boundaries of the classroom. However, this increase in the use of social networking in academia presents many potential issues. In this paper, we address the growing prevalence of social networking in education and some of the issues. Next, we use social role theory to explore some pitfalls for educators using social networking. Finally, we suggest that foundational ethical principles from the field of psychology can provide a basis for developing guiding principles for use of social networking in education.  相似文献

The present study considered the reliability and validity of the 78-item revised version of the Multicultural Personality Questionnaire, a multidimensional instrument aimed at measuring multicultural effectiveness of expatriate employees and students. The questionnaire includes scales for cultural empathy, open-mindedness, emotional stability, social initiative and flexibility. Participants were native and foreign students of an international business school (N=171) in the Netherlands. The MPQ scales appeared to be more strongly predictive of adjustment of international students as compared to native students. Moreover, the instrument was able to explain variance in students’ adjustment beyond self-efficacy.  相似文献

Lack of benefit of warm up on prolonged intermittent-sprint performance has been proposed to be due to use of a pacing strategy by participants. To investigate this, twelve participants performed four cycle trials that consisted of either prolonged intermittent-sprint performance (80 min) or single-sprint performance (4 s), with or without a warm up. The first-sprint of intermittent-sprint performance was also assessed. No interaction effects (P > 0.05) were found between trials for intermittent-sprint performance for total work (J · kg(-1)), or percentage work and power decrement. Work done during the first-sprint of intermittent-sprint performance (no warm up) was less (P < 0.001) than the first-sprint of intermittent-sprint performance (warm up; effect size (ES) = 0.59) and both single-sprint trials (warm up and no warm up; ES = 0.91, 0.75, respectively). Peak power (W · kg(-1)) for single-sprint (warm up) was greater (P < 0.05) than single-sprint (no warm up), and the first-sprint of intermittent-sprint performance (warm up and no warm up). Warm up improved single-sprint performance and the first sprint of intermittent-sprint performance. Use of a pacing strategy probably resulted in similar intermittent-sprint performance between trials. These results suggest that team-sport players should perform a warm up at the start of a game or before substitution during a game.  相似文献

Mobile messaging systems, particularly those that incorporate social networking capabilities, affect how individuals socially interact and how they exchange information. This paper reports the impact of a mobile-device-based social networking service that enables users to form groups and send both text and photos to co-members. Survey and system usage data from 19 participants over 16 months were analyzed using information ground theory, which focuses on how people share everyday information in informal social settings. This study was novel in applying the theory to an online environment. In addition to how the mobile system functions as an information ground, the results highlight the types and usefulness of information shared, the role of information shared in everyday life, and how the system fits into participants' communication and social “ecosystem.” Usage analyses describe message sending frequency and system participation levels in relation to other factors, such as length of time in the system. Findings are discussed in the context of the information ground framework's seven propositions, to which we propose adding an emergent concept: “information capital,” i.e., an individual's capacity to access information based on his/her information grounds extent, and degrees of social capital and information literacy.  相似文献

Despite more than 15 years of research into the implementation of flexible access to school library media programs in the United States, few empirical studies exist that examine the relationship between access scheduling and school library media circulation. This quantitative study examines the relationship between types of school library schedules and circulation. Examination of end-of-year circulation statistics for fixed, flexible, and partially flexible elementary school library media centers in North Carolina and Virginia indicate that there was a significant and positive relationship between flexible scheduling and per-pupil book circulation in elementary schools in these two states.  相似文献
