Sexting is one of the recurring causes of concern in public discussion of young people and network media. This paper builds on findings from a survey with 1269 Finnish female respondents aged 11–18 conducted using a popular online community for girls on their experiences of and views on online messages concerning sex and sexuality. Sixty-five per cent of respondents had received messages related to sex from either adults or minors while 20% had also sent such messages themselves. The paper asks how girls experience and make sense of sexual messaging and what motivates them to engage in such interactions. Specific attention is paid to the distinction between unwanted and wanted messages. While messages from unknown people identified as adult were often discussed as unpleasant or ‘creepy’, sexual messaging, role-play, cybersex experiments and discussions related to sex among peers were defined as fun and pleasurable. Girls display notable resilience and describe coping strategies connected to unwanted messaging but equally frame sexual messaging and role-play as issues of choice motivated by curiosity and pleasure. The paper addresses sexual messaging as a form of sexual play and learning, and argues for the importance of contextual analysis in understanding its forms and potentialities. 相似文献

Young adults are disproportionately affected by negative sexual health outcomes, such as sexually transmitted infections. One strategy for reducing such negative outcomes involves the use of comprehensive sexual health education. As comprehensive sexual health education programmes are adopted, there is a need to evaluate the messaging approaches that might best connect with young people. Sex-positive approaches, which describe sex as a healthy practice and personal choice, are becoming popular, but whether this strategy works has not been tested from a message design perspective. This study examines the reactions of young adults to sex-positive or sex-negative messages, framed as a gain or loss, designed for a text message-based intervention. Participants quantitatively evaluated 24 messages on their mobile phones. Gain frames were preferred over loss frames, and sex-positive messages were rated as more believable and persuasive. An interaction between the two concepts was also found. Results highlight how sex-positive messages that focus on the benefits of certain behaviours tend to resonate better with young adults. Implications for health educators and practitioners are discussed. 相似文献

Prior literature suggests that social media users are increasingly experiencing social media fatigue. Only recently have scholars undertaken empirical studies to investigate its antecedents and outcomes to better understand the impact of fatigue on social media users. To further this understanding, the present study has conducted a cross-sectional survey with 1552 users. The Stress-Strain-Outcome (SSO) theoretical framework is applied to examine if privacy concerns, self-disclosure, parental mediation strategies, and decrement in academic performance due to social media use correlate with social media fatigue. Two forms of fatigue are considered, namely, fatigue due to social networking site (SNS) and mobile instant messaging (MIM) use. The study results suggest that privacy concerns, self-disclosure, parental encouragement and worry significantly and positively correlate with SNS and MIM fatigue. Parental permission and parental monitoring are either not or lowly associated with fatigue. In addition to this, SNS and MIM fatigue positively correlated with the tendency to experience academic decrement due to social media use. The antecedents and consequences of social media fatigue were similar for SNS and MIM users. Moreover, students perceived their parents to be more open to their MIM use, and they had higher self-disclosure in MIM than in SNS. The study concludes with significant implications for practitioners, policy makers as well as service designers. 相似文献

即时评价是指在教育活动过程中，评价者对于评价时象的具体表现所作的即时的表扬或批评，是一种与教学过程紧密结合的“进行性评估”，贯穿于学习过程当中。体育课堂教学中教师即时评价是对学生课堂学习活动作出的立即反应，帮助调整，控制后继学习行为。“促进发展、以人为本、强化激励、多元参与”是新课程课堂教学即时评价的新特点。文章结合初中体育课堂教学实践通过对课堂教学中的即时评价的重要性以及实施策略进行阐述，从而充分发挥即时评价的功能，促进学生的全面发展。 相似文献
