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。     

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.     

The exemplarities of artworks: Heidegger, <Emphasis Type="Italic">Shoes</Emphasis>, and <Emphasis Type="Italic">Pixar</Emphasis>

Heidegger’s essays “The Origin of the Work of Art” and “The Question Concerning Technology” provide a revealing insight into the importance of exemplarity to artworks. Originally the notion that exemplarity is essential to art is Kantian: As Kant puts it, since originality can produce “original nonsense, [beautiful art’s] products must be models, i.e. exemplary.” However, what Heidegger recognizes is that even if exemplarity allows us to take art seriously in spite of its excesses, it exposes the artwork to new dangers: on the one hand, to the “world withdrawal of the work” as occurs in consignment to the museum shelf, and on the other, to the conditions of Enframing as “challenging-forth,” under which art is taken as a means to an end—dangers which point to the division of artworks between “fine” art and “popular” art. Since Heidegger’s approach favors the former, we will try to gain new critical insight by considering his arguments in the light of a “popular” work that allows us to formulate an exemplarity of popular art as the necessary complement to that of traditional art. By means of an understanding of the exemplarities (in the plural) of artworks, we will be able to reconsider the significance of Heidegger’s notions of reliability, Enframing, and poiesis for our current technological conditions.

‘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.
