ABSTRACT

Social media is a powerful tool for building an online presence, but it asks a lot. While it affords plentiful opportunities for professional development and networking, building a professional brand in an online space is not without its drawbacks and risks. By working from a set of actionable principles and benchmarks, users can minimize frustrations and setbacks to build a useful professional presence, all while imbuing the web with the tenets of good information stewardship.  相似文献

A rich literature exists reinforcing the notion that both perceived and received social support has stress ameliorating and protective benefits both psychologically and physiologically. However, recent literature suggests that excessive dyadic negative problem talk about an issue, a phenomenon labeled co-rumination, may reverse much of the beneficial effects of social support. Healthy young adults participated in a laboratory research study exploring the associations between co-rumination and immune system inflammatory response. Partial correlations indicated a positive association between co-rumination and C-reactive protein and a negative association between co-rumination and interleukin-6 after controlling for stress, anxiety, and temperature. Discussion focuses on the means by which co-rumination may lead to negative health outcomes.  相似文献

This article explores people’s susceptibility to political deception. Participants watched a news interview in which a politician either answered all the questions or deceptively evaded a question. In Study 1 (n = 202), deception is perceived through the dodge being irrelevant for voters who do not identify with the politician. In Study 2 (n = 618), partisan voters consider the politician more deceptive, and acting more deceptively, when the politician has their opposing party affiliation, independent of whether he dodges. When the politician shares their party identification, voters identify with the politician more and consider his responses more relevant. Findings are consistent with theoretical positions of identification, the cooperative principle, and social identity.  相似文献

This introductory article to the combined special issue of Journalism Studies and Journalism Practice provides an overview of some of the key contemporary approaches to studying journalism and social order. It argues the need to step beyond a functionalist framework when considering the news media’s central role in shaping social connections, community and cohesion. To advance our understandings of social order, our paper suggests a greater emphasis of the significance of journalism’s relationship to the wider social sphere along with three other key considerations, including (1) a critical focus on the relationship between media, politics and social order, especially in defining and/or negotiating “anti-social” practices and social disintegration; (2) a more refined focus on the “imagined” and geographic boundaries of news audiences in digital spaces; and (3) the changing relationship to norms and conventions of journalism practice from trust and legitimacy to the role of journalists as arbiters and connectors across social spaces.  相似文献

This article explores the existence of a “citizen-centered journalism” that sees citizens as crucial participants in the construction of news and as co-creators of their own worlds. Through qualitative case studies of three news organizations, the article examines the motivation for using a citizen-centered approach, the news routines that are required to do so, the categories of content produced, and the perceived impact of this approach. The results suggest these news organizations are working in partnership with communities and striving to give a voice to historically marginalized communities. The journalists, however, see citizen participation as complementary to professional journalistic routines that favor verifiable information, rather than assigning inherent value to it for its own sake.  相似文献

水稻千粒重QTL图谱整合研究   总被引:3,自引:0,他引:3  
以粳稻品种日本晴的测序图谱Gramene Annotated Nipponbare Sequence 2006为基础,挑选较广泛应用于水稻QTL研究的标记绘制了公共图谱.并将国内外公开发表的251个水稻千粒重QTL整合到该图谱中.研究表明,目前定位的粒重QTL虽分散于各条染色体,但主要集中在1、3、5、6、10号染色体上并成簇状分布,其中6个区间可能存在主效QTL.  相似文献

“深度信念”是怀特海文稿中的关键概念。在怀特海有机哲学看来,动机、方法和意义是一个整体。他懂得要在深层次上探查人类追求意义及理解的倾向,进而揭示“追求”行为中的创造张力。深度信念就是这种深层次的动力。深度信念不同于各种各样起源于文化传统的信仰或偶发的信念,它不像后者那样可能失去。怀特海认为,在个人经验中,某一个信念的失去更可能是“无限性激励下的有限性”,是某种“超越的内在性”,“朝向更精美细致的结果”。深度信念促成了精神的冒险,是人类固化成就中不可抹去的最富锐气的因素,是人的呈现。  相似文献
