John Nerone 《Media History》2015,21(1):1-7
This article introduces a group of articles on the history of paper and issues of scarcity in the history of newspapers and news media generally. The articles discussed share a concern with the parallels between paper scarcities in newspaper history and spectrum scarcities in broadcast history. This introductory essay comments on the similarities and differences between the two kinds of scarcity and comments more broadly on the rise and fall of bottlenecks in media systems, paying attention both to how scholars have discussed materialities of media communication and how legacy news media in the digital era have encountered a new competitive landscape. 相似文献

语言学习是一个不断掌握新知识的过程,学生对新知识的理解和掌握是建立在原有知识和经验的基础之上的。然而,有时候由于原有知识的局限性,会与新知识产生;中突,从而阻碍学习者理解和接受新知识。相异构想就是学生原有的知识与科学知识不一致的认识,它对学生学习英语产生较大的负面影响。本文阐述了什么是相异构想、它的成因和特点,在此基础上提出了纠正学生相异构想的建议,以提高教师教和学生学的质量和效果。 相似文献

This paper examines findings from a recent study in Wales of school exclusion and alternative educational provision. Many, but not all, children in alternative provision have been excluded from school. The most recent statistics reveal that nearly 90% of pupils in alternative provision have special educational needs, nearly 70% are entitled to free school meals (free school meal entitlement is often used as a proxy indicator for poverty in the UK) and three quarters are boys (Welsh Government. 2012a. Pupils Educated Other than at School, 2011/12. Cardiff: Welsh Government). The paper focuses on analysis of findings about young people's experiences of exclusion and alternative provision, and how these experiences may be contextualised within a discussion of children's rights. This analysis suggests that young people's experience is highly variable; that inappropriate curricula are still common, pastoral support uneven and that few opportunities exist for success or re-integration. In the most disturbing examples, young people were found to have experienced physical restraint and the use of isolation as punishment. The paper concludes, therefore, with a proposal for change aimed at ensuring that children's rights are placed at the heart of educational experience in practice as well as policy. 相似文献

Families with complex needs related to domestic violence, mental health, and substance use have some of the worst child protective services (CPS) outcomes. Although many of these families are identified during a CPS investigation and subsequently referred to home-based postinvestigation services (HBPS), many are re-reported to CPS, so it is important to understand the postinvestigation experiences of this vulnerable group. Therefore, this study compared families with and without complex needs to understand their uniquedemographics, needs, and postinvestigation outcomes.The sample consisted of 2008 caregivers who received HBPS following an initial CPS investigation. The Family Assessment Form (FAF) was used to measure family functioning in eight domains using a 1–5 scale with higher ratings representing worse functioning. Complex needs were indicated by a mean FAF score of 3 or higher for either domestic violence, mental health, or substance use. Using Pearson chi-square analyses and two-sample t-tests, comparisons were made between families with (n = 836) and without (n = 1172) complex needs. Half of caregivers with complex needs had a history of abuse, 25% had three to five needs, and nearly half had six to eight needs; 90% of caregivers without complex needs had zero to two needs. Furthermore, caregivers with complex needs had higher mean scores for concrete, educational, and clinical needs. These findings highlight the importance of recognizing variation among families referred to HBPS and accurate screening to ensure that families with complex needs are offered and receive services matched to their unique characteristics and needs. 相似文献

Using a survey of a sample of hyperlocal actors in Sweden (N?=?178), this article examines preconditions, motivations and sustainability for hyperlocal media operations, outside the traditional media chains, in order to provide a picture of their function in the current media landscape, and to further build on the understanding of the hyperlocal business model. This study extends the hyperlocal definition by including media platforms other than websites. The results show that the operations indeed aim to support and foster citizenship, strengthen democracy and mirror the local community. At the same time, as shown by other studies, the fact that they are not large-scale, highly profitable operations may challenge their sustainability. Nonetheless, most of them claim to be profitable, largely because of the print platform, and have a positive outlook on the future. Revenues from advertising and readership are currently less substantial for Web-based operations, which reinforces the need to broaden the definition of hyperlocal publishing platforms when talking about financial sustainability. Currently, hyperlocal media in Sweden, with small resources and a lower publishing frequency, cannot be viewed as a replacement of established media, but play important roles as complementary alternative voices and contribute to media plurality in the local community. 相似文献

本文提出一种以拼音与笔画相结合的中文报纸排架排序法。因其依照"拼音为主、笔画为辅,拼音与笔画相结合"的原则,根据报纸名称的拼音和笔画对报纸进行编码排序,故称为音画码排架排序法。此方法可灵活运用在开架报纸排架和闭架报纸库排架中,能给读者和图书馆工作人员带来极大的便利。 相似文献

纵向来看,江西日报报业集团报纸官微走过了“空档频出、时段集中、质量较低、定位不明”的试水期和“空档减少、时段分散、纸媒窗口、直播频现”的起步期,进入到“逐日更新、早晚覆盖、信源多元、质量提升”的发展期。横向来看,各报纸官微运营水平差距明显,运营模式各不相同,运营关联较为薄弱。面对媒体发展新态势,江报集团报纸官微应积极构建微博矩阵,实现流程再造;突显区域特色,塑造优势品牌;强化传统优势,追求差异生存;增强数据分析,达成精确推送;精选团队成员,力促基因重组。在服务地方发展,打通“两个舆论场”和凝聚社会共识中发挥应有的重要作用。 相似文献
