借助新媒体提升“90后”大学生思想政治教育的实效性

在经济全球化、思想文化多元化、信息化和科学技术飞速发展、我国综合国力和国际竞争力不断增强的背景下,新媒体已渗透到人们日常生活的方方面面。＂90后＂大学生呈现出独特的思想、行为模式,给大学生思想政治教育工作带来挑战。因此,认清和把握＂90后＂大学生的思想、行为特点,充分借助新媒体的优势,有针对性地开展大学生思想政治教育工作,提升思想政治教育工作的实效性显得尤为重要。     

Curation: a theoretical treatment

Curation is a key mechanism of sociality in a digital era. With an abundance of information, sifting, sorting, selecting, hiding, and standing out become laborious tasks. While researchers have diligently documented people’s curatorial strategies, digital curation remains undertheorized in its own right. I therefore theorize digital curation by disentangling productive curation from consumptive curation, addressing how people curate content that they share, and that which they consume. I embed these agentic curatorial practices within structural bounds, both social and technological. In doing so, I offer a basic theoretical model that captures a dynamic relationship between individual curators, their social networks, and technological design.     

Housing hardship and energy insecurity among native-born and immigrant low-income families with children in the United States

The costs for rent and utilities account for the largest share of living expenses, yet these two critical dimensions of material hardship have seldom been examined concurrently in population-based studies. This paper employs multivariate statistical analysis using American Community Survey data to demonstrate the relative risk ratio of low-income renter-occupied households with children experiencing ‘rent burden', ‘energy insecurity', or a ‘double burden’ as opposed to no burden. Findings suggest that low-income households are more likely to experience these economic hardships in general but that specific groups are disproportionately burdened in different ways. For instance, whereas immigrants are more likely to experience rental burden, they are less likely to experience energy insecurity and are also spared from the double burden. In contrast, native-born African Americans are more likely than all other groups to experience the double burden. These results may be driven by the housing stock available to certain groups due to racial residential segregation, decisions regarding the quality of housing low-income householders are able to afford, as well as home-country values, such as modest living and energy conservation practices, among immigrant families. This paper also points to important policy gaps in safety net benefits related to housing and energy targeting low-income households.     

Exploring the role of the Senate Majority Leader's political public relations efforts

Grounded in first- and second-level agenda building, this study explored the role of the U.S. Senate Majority Leader in shaping the salience of issues and issue attributes in news media coverage and policymaking in 2011. A total of 358 public relations messages, 164 newspaper articles, and 83 policymaking documents were analyzed. Significant correlations were found supporting agenda-building linkages at both levels. Different types of information subsidies were explored, including press releases, blog posts, Facebook posts, and Twitter messages.     

Building relationships through websites: A content analysis of Turkish environmental non-profit organizations’ (NPO) websites

This paper provides insight into the dialogic potential of Turkish environmental NPO websites, including social media adoption. However, 23 of 50 websites examined failed to meet half the criteria for building relationships (n 35). Of 19 sites with connections to social media, 16 used new media potentialities, however only four met all social media adoption criteria.     

Hybrid social and news media protest events: from #MarchinMarch to #BusttheBudget in Australia

Public protest events are now both social media and news media events. They are deeply entangled, with news media actors – such as journalists or news organisations – directly participating in the protest by tweeting about the event using the protest hashtag; and social media actors sharing news items published online by professional news agencies. Protesters have always deployed tactics to engage the media and use news media agencies’ resources to amplify their reach, with the dual aim of mobilising new supporters and adding their voice to public, mediatised debate. When protest moves between a physical space and a virtual space, the interactions between protesters and media stop being asynchronous or post hoc and turn instantaneous. In this new media-protest ecosystem, traditional media are still relevant sources of information and legitimacy, yet this dynamic is increasingly underpinned by a hybrid interdependency between traditional news and social media sources. In this paper we focus on an anti-austerity government movement that arose in Australia in early 2014 and was mobilised as a series of social media driven, connective action protest events. We show that there is a complex symbiotic interdependency between the movement and the traditional media for recognition and amplification of initial protest events, but that over time as media interest wanes, the movements’ network becomes disconnected and momentum is lost. This suggests that the active role traditional media play in protest events is being underestimated in the current research agenda on connective action.     

How social media matter: Repression and the diffusion of the Occupy Wall Street movement

This study explores the role played by social media in reshaping the repression-mobilization relationship. Drawing on the case of the Occupy Wall Street movement, we examine the impact of Facebook and Twitter on the spatial diffusion of protests during a period of heightened state repression. Results from event history analyses suggest that the effects of repression on protest diffusion are contingent on the presence of social media accounts supporting the movement. We find that state repression at earlier protest sites encouraged activists to create Facebook and Twitter accounts in their own cities, which then served as important vehicles for the initiation of new Occupy protests. Moreover, results suggest that repression incidents can directly facilitate future protests in cities that already have Occupy Facebook accounts. This study highlights the potential of social media to both mediate and moderate the influence of repression on the diffusion of contemporary movements.     

我国企业品牌定位的五层次研究

近年来中国企业的品牌建设取得了可喜的成绩,出现了许多优秀品牌,这些品牌凭借独特、合适的定位取得了成功。但企业在品牌定位方面存在许多误区,如把品牌定位看作产品定位、品牌定位模糊,缺乏差异性和明确的核心价值、品牌盲目延伸导致定位混淆等问题。因此,产品品牌定位必须树立正确的定位理念,应用正确的品牌定位方法。正确的品牌定位方法可分为产品特征定位、物质利益定位、情感利益定位、个性定位以及价值观定位共五个层次。     

社会化媒体时代科普宣传的路径厘析

社会化媒体时代已经来临，信息传播逐渐由内容为主步入渠道为主。新媒体、新技术的发展为科普工作的开展带来了新的机遇，即提供了更为广阔的渠道、更为丰富的内容和更为多样的呈现形式。但是，机遇与挑战并存，新媒体的发展在给科普工作带来机遇的同时也带来了挑战，主要表现在：信息的多元、多变、多样淹没了科普信息；虚假、伪科学、迷信信息大行其道；网民习惯性质疑挑战权威（权威到威权）；科普信息的枯燥无法吸引网民等问题也较为突出。如何在社会化媒体环境下赢得话语权，抢占科普宣传制高点，已经成为当前开展好科普工作的重要任务。     

An evaluation of the tandem configuration automated guided vehicle system

The performance of a tandem automated guided vehicle (AGV) system is compared with that of conventional AGV track systems. In the tandem system the track is divided into non-overlapping, single-vehicle closed loops. Using simulation it is shown that, because of trips requiring delivery across loops, the tandem system has a higher expected travel time per load and thus a greater average time in system. When the loads are delivered within the original loop only, the tandem system has a lower average time in system than in conventional systems, although the difference is modest. Track layout appears to influence the average time in system much more than docs the dispatching rule invoked. The success of the tandem system is highly dependent on approximately even AGV utilization, which may be difficult to obtain in practice.
