对新闻采访中偷拍偷录合法化问题的研究

偷拍偷录是指未经他人知晓或同意,对他人的活动进行拍照、摄像或对其谈话进行录音的采访行为,其法律实质是采访权的重要内容。采访权是保障新闻真实与新闻自由、满足公众的知情权,揭露违法违纪现象,鼓励舆论监督、维护公共利益并实现社会公正的迫切需要,肯定作为采访权重要内容的偷拍偷录的合法性十分必要。我国现行法律尚未对采访权以及偷拍偷录作出明确规定,在实践中出现了不少问题,应当根据社会生活的实际需要,尽快完善新闻立法,使偷拍偷录合法化。     

一种面向主题覆盖度与权威度的评审专家推荐模型研究

[目的/意义] 为投稿论文遴选出合适的审稿专家是论文发表过程中关键的一环。随着投稿论文和候选评审专家数量的持续增长,人工指定评审专家的方法在准确性和公平性上的弊端日益显露出来。因此,为进一步提高专家评审的客观性和准确性,笔者从专家知识与专家权威度两个维度对专家建模,并以此为依据为不同主题的投稿论文遴选推荐评审专家。[方法/过程] 首先分析专家知识以及投稿论文的研究内容,并提取两者涉及的多个子研究主题;然后,计算专家知识对投稿论文子主题的覆盖度,并提出融合主题特征与时间特征的权威度算法TTAM来分析专家权威度;最后,提出融合主题覆盖度和专家权威度的专家推荐框架CAUFER,综合考虑覆盖度和权威度两个因素为投稿论文推荐合适的评审专家。[结果/结论] 实验结果表明,与经典的基于向量空间模型、语言模型和作者主题模型3种专家推荐算法相比,笔者提出的算法能够较好地提高专家与投稿论文的匹配度,并可据此追踪专家权威度的变化,刻画专家在特定主题下的权威度,进一步提高专家推荐的准确性和科学性。     

Bias vs. Bias

When Pope Francis, the leader of the Roman Catholic Church, released his encyclical on climate change in June 2015, the Fox News Channel, the most watched cable news network in the United States, faced a dilemma. Some of its news anchors and regular commentators are Catholics, and therefore have a positive bias for the Pope. But the network is also known for its bias against man-made climate change. Guided by cognitive dissonance theory, this study analyzed how Fox News’ anchors and commentators discussed Pope Francis’ stance on climate change. The analysis found a clear ambivalence in their discourse and identified four discursive strategies that they used to navigate discursive dissonance.

Exertional Heat Stroke of Max Gilpin; A Preventable Death

ABSTRACT

Exertional heat stroke (EHS) is a medical emergency whose likelihood in sport settings is often contingent on environmental factors, team policies, coaching strategies, and broader cultural expectations. Moreover, when it occurs, it requires immediate recognition, proper management, and care to optimize chances of survival or recovery without long-term sequelae. Max Gilpin, a secondary school American football player from Louisville, Kentucky, suffered an EHS during a football practice in August 2008, an event that resulted in his death. The purpose of this article is to use interdisciplinary methods to identify key factors that contributed to this tragedy so that similar situations do not happen again. It concludes that within a culture of inclusive gender norms and care, efforts should be made to have appropriate onsite medical expertise available to develop and implement best practices for the prevention, management, and treatment of EHS, along with coaching education specific to medical emergencies in sport and physical activity (such as EHS). This will create an environment that promotes health and safety for all student athletes participating in sport at the secondary school level.     

The tension between curriculum coverage and quality learning: The experiences of South African teachers

In South Africa, there is increasing state monitoring of curriculum coverage. This is a response both to classroom research which shows that teachers do not always cover the official curriculum in the specified year and to learners’ poor achievement in international tests. In the province of KwaZulu-Natal from 2013 to 2016, the provincial department of education embarked on a systemic reform programme called Jika iMfundo in 1200 schools, which is focused on improving curriculum management and coverage. We interviewed 29 Heads of Department (who are also teachers) in fifteen schools who had participated in the Jika iMfundo programme for these three years, asking them about their experiences. The findings show that teachers experience tension between the fast pace required by the curriculum trackers and slow pace of learners and they believe that increasing pacing to cover the curriculum hampers the quality of the learning. Teachers also said that the curriculum coverage trackers do not account for different school contexts. We argue that while the programme has provided clear curriculum guidance to teachers who need it, it has not sufficiently acknowledged the huge variation in learners’ competence. Nor has it yet enabled teachers to develop the content knowledge and the pedagogical content knowledge necessary to teach learners who are not at the same grade level (although they are in the same classroom). Curriculum coverage is a necessary, but not sufficient intervention, unless there is also a focus on pedagogy and teaching at the right level. We recommend an intervention that enables teachers to identify individual learner’s existing learning gaps, and equips them to teach at the right level in order to provide learners with opportunities to develop foundational knowledge and skills to succeed in further education, rather than one whose primary focus is only curriculum coverage.
