考虑重复购买因素的品牌竞争对新产品扩散的影响研究——基于小世界网络的仿真环境

在对品牌竞争影响要素分析的基础上，考虑重复购买在新产品扩散过程中的调节效应，构建以消费者微观采纳机制为核心的新产品扩散的阈值模型，在小世界网络仿真情境下，运用多智能仿真方法对品牌竞争与新产品扩散之间的影响关系进行分析，研究结果表明：转换成本对新产品扩散的速度和深度的影响存在一定的"条件区域"，在该区域之外两者不存在显著的影响关系；进入时间与两种竞争性品牌的扩散速度存在一致的负向的影响关系，而对两种竞争性品牌的扩散深度的影响方向则相反；在此过程中，重复购买系数起着一定的调节效应，会在一定程度上放大或缩小转换成本及进入时间对新产品扩散的影响效应。通过本文的研究，不仅可以进一步丰富和完善竞争性产品创新扩散的相关理论，也可以为企业的新产品推广实践提供决策支持。     

新生代乡村教师的离职意向与政策改进

新生代乡村教师是乡村教育的新生力量和未来的中流砥柱，他们能否安心留在乡村学校从教，关系着乡村教育的可持续发展。为解决乡村教师"留不住"的问题，国务院办公厅于2015年6月发布《乡村教师支持计划（2015-2020年）》，从经济待遇、社会地位、专业发展等方面着手，提出了具体措施。但是通过实证研究发现：当前新生代乡村教师的离职意向仍然普遍存在，尤其是其中的男教师和工作在乡村小学的教师；新时代乡村教师的离职意向，受经济待遇、社会地位、专业发展、个人偏好、乡村文化适应性、家庭和学校支持度、教师教育满意度等多方面因素的影响，其中个人偏好和乡村文化适应性是最主要的影响因素。因此，为了更好地留住新生代乡村教师，仍需在"乡村教师支持计划"现有政策支持的基础上，进一步补充和完善相关的政策措施：（1）重视乡村教师招聘和管理过程中对个人偏好的考察与培育；（2）积极帮助新生代乡村教师适应乡村文化；（3）关心新生代乡村教师的家庭问题，提供帮助和支持；（4）重视乡村学校建设，给予新生代乡村教师更多的组织关怀；（5）出台针对乡村教师的教师教育标准。     

新时代大学生担当精神及其培育体系的构建

新时代培育民族复兴大任的时代新人，必须提升大学生的担当精神，以建设一支有担当、敢担当的时代新人队伍，这是应对时代诉求与历史使命的必由之路。然而，大学生的担当精神培育既面对着认知新的历史方位、奋力托举中国梦与应对新“忧患”的时代诉求；又要面对围观的看客心态、非科学的失衡心理、认知偏颇的冲击。因此，把担当精神摆在育人的重要位置，从升级育人内容、优化育人环境等几个关键教育环节着手，营造崇德向善、力争担当的社会风尚，将担当精神培育生活化、长效化，进而不断增强大学生的担当意识与担当力。     

Media Exposure to Terrorism and Perception of Immigrants as a Threat: The Role of Emotional Intelligence and Psychophysiological Self-Regulation

To better understand how media exposure to terrorism-related images can lead to perceiving immigrants as more threatening, in the present study we manipulated participants’ exposure to media coverage of terrorist attacks and investigated how this may influence people's perception of Arab immigrants. Considering the important role of regulatory abilities when facing stressful events like terrorist attacks, we measured individual differences in both trait emotional intelligence and resting heart rate variability (HRV). Results showed that participants perceived Arab immigrants as more threatening in the media exposure condition than in the control condition. Importantly, there were moderating effects of both trait emotional intelligence and HRV. People with lower trait emotional intelligence or lower HRV at rest felt more threatened in the media exposure condition compared to the control condition, whereas this effect was not observed among participants with higher trait emotional intelligence or higher resting HRV. The present study highlights some of the complexities related to how media exposure to terrorism-related images influences people's reactions to, and evaluations of, an outgroup that is related to the perpetrators of the attacks.     

网络服务提供者著作权侵权中的双重注意义务

《民法典》侵权责任编对原有通知删除规则进行了科学修正，但事前保护缺位与事后救济程序失范的问题仍然存在。随着网络服务提供者完成角色转型和技术升级，其作为网络侵权风险的控制者和参与者，有必要且有能力承担未通知阶段的主动预防义务和已通知阶段的证明材料审查义务，以弥补著作权保护和用户利益保护的漏洞。双重注意义务应分别与网络服务提供者对侵权危险的预期和控制能力以及材料审查能力相适应。未通知阶段之注意义务以技术措施为主要履行方式，其注意标准的认定应综合考量技术水平、服务类型、内容介入程度、是否直接获取收益等要素，未尽该注意义务仅为过错认定的考量因素而非唯一标准，并不必然导致侵权责任。已通知阶段之注意义务仅限于对提交的证明材料进行形式审查和有限的实质审查，尽到此注意义务的，可以免于承担侵权责任。

Techniques of disinformation: Constructing and communicating “soft facts” after terrorism

Informed by social media data collected following four terror attacks in the UK in 2017, this article delineates a series of “techniques of disinformation” used by different actors to try and influence how the events were publicly defined and understood. By studying the causes and consequences of misleading information following terror attacks, the article contributes empirically to the neglected topic of social reactions to terrorism. It also advances scholarship on the workings of disinforming communications, by focusing on a domain other than political elections, which has been the empirical focus for most studies of disinformation to date. Theoretically, the analysis is framed by drawing an analogy with Gresham Sykes and David Matza's (1957) account of the role of “techniques of neutralization” originally published in the American Sociological Review. The connection being that where they studied deviant behaviour, a similar analytic lens can usefully be applied to disinformation cast as “deviant” information.     

How publics react to situational and renewing organizational responses across crises: Examining SCCT and DOR in social-mediated crises

The prevalence of social media among networked publics calls for more research regarding how organizations can conduct effective crisis communication on social networking sites. Based on the situational crisis communication theory (SCCT) and the discourse of renewal (DOR) theory, this study examined how social media publics’ sentiments were affected by situational and renewing organizational responses in various clusters of crises. Twitter data of six crises representing three crisis clusters varying in the responsibility attribution (i.e., ambiguous, accidental, and preventable) were collected. We conducted a content analysis on organizations’ official tweets during crises (N = 59) and sentiment analysis on publics’ replies on Twitter (N = 4,340). The results showed that publics’ positive sentiments toward organizations were affected by organizational crisis responses that included instructing information, sympathy, systemic organizational learning, and effective organizational rhetoric. We recommend that crisis managers express sympathy toward publics as well as organizational learning that prevents a crisis from happening again.     

Truth® ads,receptivity, and motivation to use or quit tobacco among college students

Abstract

Objective: Examine receptivity and motivation to use/quit tobacco among college students after viewing Truth ads. Participants: Random sample of 10,000 college students invited to complete online survey February 2016 (8.5% response rate). Methods: Quasi-experimental. Participants (N?=?854) watched four ads and answered survey items for each ad. Results: Students rated ad receptivity and decreased motivation to use tobacco higher for the Catmageddon ad than the others. Regardless of ad, men and current cigarette smokers reported lower receptivity. Younger age was associated with lower motivation to use tobacco for all ads. Tobacco users reported greater motivation to quit with the Catmageddon ad. Conclusions: College students were receptive to the Truth ads, and many indicated lower motivation to use tobacco. Men, older college students, and current cigarette smokers were less receptive to the ads, reinforcing the need to develop tailored campaigns to reach these subgroups.     

Searching for the “Sleeping Giant”: Racialized News Coverage of Latinos Pre-2020 Elections

Latinos are often thought as potential game changers in the political world in the United States. As the media discusses and analyzes the 2016 election and the path to the 2020 elections, narratives on the role of Latinos leading up to the 2020 election have started to emerge. In this article, I seek to examine how U.S. daily newspapers frame the role of Latinos in the 2016 election and leading up to the 2020 elections. Previous literature has focused on the racialized media coverage of African American politicians and the effects of racial priming; however, extant literature has not explored how Latinos are framed in U.S. media when it comes to electoral politics. Using a sample of newspaper articles from the New York Times, Los Angeles Times, Washington Post, and Wall Street Journal, I found that newspapers largely focus on the demographic changes while operating under various assumptions about those changes. First, newspapers frame Latinos as more likely to vote for a politician if they are Latino. Second, they construct Latinos as a monolithic ethnoracial group that has simplistic interests in immigration. Third, Latino voters and African American voters are often lumped into the same category when discussing mobilization. These narratives continue a tradition of framing Latinos in monolithic ways, while also showing slight departures from previous narratives.
