民警社交媒体自我呈现对工作满意度的影响—积极情绪的中介作用

为探讨民警在社交媒体中自我呈现策略与工作满意度的关系,以及积极情绪的中介作用,采用积极情感消极情感量表、工作满意度量表以及自我呈现问卷对242名民警进行问卷调查,结果表明：（1）民警在社交媒体中的积极自我呈现和真实自我呈现分别与积极情绪、工作满意度两两之间显著正相关,积极自我呈现与积极情绪、工作满意度的相关性更高;（2）民警在社交媒体中的积极自我呈现和真实自我呈现对工作满意度有正向预测作用,并通过积极情绪的中介作用对工作满意度产生影响。     

工作场所社交媒体使用对员工工作绩效的影响：基于人际关系视角

基于社会交换理论和分心冲突理论,本研究探讨了社交媒体使用对员工工作绩效影响的作用机制。通过“领导者-下属”配对的问卷调查法对147名员工进行调查,采用Bootstrap检验对模型中的多重中介效应进行检验。结果发现：（1）社交相关的社交媒体使用与员工工作绩效各维度间显著正相关;（2）社交相关的社交媒体使用对工作绩效不同维度的影响存在显著差异,通过增加人际信任对工作奉献和任务绩效产生影响,通过缓解关系冲突对人际促进和任务绩效产生影响。     

The Internet is a scary place: How does evidence source and examinee race or ethnicity influence determinations of threat?

Violent rhetoric online is becoming increasingly relevant to the practice of forensic mental health assessment as examinee's virtual lives may transform into real-world acts of violence. With the rise of a diverse subculture of violent online communities, the aim of the present study was to inform how concerns with online sources of collateral data and racial/ethnic biases may influence determinations of violence potential. Using an experimental design, jury-eligible participants (N = 278) and forensic mental health experts (N = 78) were presented with mock Twitter (now referred to as X) posts that varied by data source (i.e., how information was accessed) and the examinee's race/ethnicity. Results showed no differences in participants' ratings of data credibility, how much weight they would place on the posts in a threat assessment, or how likely the examinee was to act violently against his intended target. Implications regarding the interpretation of social media evidence, relevant limitations, and future research are discussed.     

Truthfulness,Beneficence, and Vulnerability as Key Concepts in Communication Ethics

This article presents the major stages of the approaches to the ethics of communication and the respective ethical principle of each one. The first stage, centred on the principle of truthfulness, was born at the beginning of the 20th century, at the same time as the first great development of the press and journalism. The second stage, which began at the end of the 20th century, centred on the principle of beneficence and developed from the growing influence of the mass media on all fields and aspects of social life. There is also the need for a further principle for communication ethics: the principle of vulnerability: to give voice to those affected by a situation, especially to those in a situation of vulnerability. The article then considers whether the huge impact of the Internet and social media at the beginning of the 21st century implies a new stage in the ethics of communication or rather the need to extend the scope and effectiveness of existing ethical principles and norms. The article tends toward the second option, insisting on the role of self-regulation and media literacy in tackling the current challenges in media and social media communications.     

Violent video game play impacts facial emotion recognition

This study assessed the speed of recognition of facial emotional expressions (happy and angry) as a function of violent video game play. Color photos of calm facial expressions morphed to either an angry or a happy facial expression. Participants were asked to make a speeded identification of the emotion (happiness or anger) during the morph. Typically, happy faces are identified faster than angry faces (the happy-face advantage). Results indicated that playing a violent video game led to a reduction in the happy face advantage. Implications of these findings are discussed with respect to the current models of aggressive behavior.     

‘Check Your Selfie before You Wreck Your Selfie’: Personality ratings of Instagram users as a function of self-image posts

This study considered the relation between self-image posts (i.e., selfies, posies) on Instagram and the personality and self-perception attributions made by unfamiliar perceivers based on those posts. Phase 1 involved 30 undergraduates who completed self-report inventories and whose Instagram posts were coded and then screenshot for the second phase. Phase 2 included 119 undergraduates from a different university. Phase 2 participants (perceivers) rated Phase 1 participants (targets) on 13 attributes (e.g., self-absorption, low self-esteem, extraversion, successfulness) based on these screenshots. Targets who posted more selfies were rated more negatively (e.g., more lonely, less successful). Although self-image posts on social media may not be clearly indicative of personality/self-perception, they may be cues for how the depicted person is perceived by others.     

New Technologies,New Identities,and the Growth of Mass Opposition in the Arab Spring

The recent revolutions known as the Arab Spring have been characterized as the products of social media. However, there is an alternative view that revolution takes place on the street or the battlefield and that the role of social media has been overstated. We argue that some new technologies can serve to facilitate rapid social change when they provide ways to overcome restrictions on the freedoms of expression and association. In doing so, communication technologies enable the formation of new social identities that can challenge existing social orders by promoting the growth of a social movement that is positioned as loyal to the nation and its people but opposed to the government. Our analyses focus on the role of social media in spreading video images of dissent and the links between this video material, satellite television, and mobile telephones in Tunisia and Egypt.
