Impression management strategies on enterprise social media platforms: An affordance perspective

Enterprise Social Media Platforms (ESMPs) are arenas for self-presentation where employees construct, co-create, and maintain an online image among their colleagues. This study systemically evaluated the current literature to understand the potential of ESMPs in influencing employees’ impression management strategies from the affordance perspective. Drawing from a focused review of the literature on ESMPs’ affordances and impression management, this paper reclassified employees’ impression management strategies in the context of ESMPs. It proposes a conceptual framework that captures the complex relationship between ESMPs’ affordances and employees’ various impression management strategies. The framework highlights that ESMPs’ affordances affect employees’ impression management strategies, both positively and negatively, and proposes the contingent effects of individual motives and boundary management on the relationship between affordances and employees’ impression management strategies. Our literature review and proposed framework provide a useful basis for future studies on impression management on ESMPs. Our framework also helps employees manage impressions strategically and managers and ESMPs’ developers to fulfil ESMPs’ potential by understanding how affordance affects impression management strategies.     

具有边界阻尼的黏性波动方程解的指数衰减性

设Ω是Rn的具有光滑边界Γ=Γ0∪Γ1的星形有界区域,这里Γ0与Γ1是不相交闭集,ν为外向单位法向量。在Ω上研究具有边界阻尼项的非线性黏性波动方程。当记忆项的核h满足指数衰减性,并非线性项F满足适当的条件时,应用扰动能量的方法证明了强解和弱解的指数衰减性。

Boundary Element Method with Non—overlapping Domain Decomposition for Diffusion Equation

A boundary element method based on non-overlapping domain decomposition method to solve the time-dependent diffusion equations is presented.The time-dependent fundamental solution is used in the formulation of boundary integrals and the time integratioin process always restarts from the initial time condition.The process of replacing the interface values,which needs a summation of boundary integrals related to the boundary values at previous time steps can be treated in parallel parallel iterative procedure,Numerical experiments demonstrate that the implementation of the present alogrithm is efficient.

Characterizing the importance of clarity of roles and responsibilities in government inter-organizational collaboration and information sharing initiatives

Previous research has shown that clarity of roles and responsibilities (CRR) influences the performance of individual organizations as well as inter-organizational efforts. In the context of cross-boundary information sharing (CBIS), CRR has been found to enable other important determinants of success, such as building trust among members, increasing their willingness to participate, and mitigating some of their concerns about security, among others. However, few studies have attempted to understand the determinants of CRR in government CBIS initiatives. Sayogo, Gil-Garcia, and Cronemberger's (2016) analysis of results of a national survey identified three significant determinants of CRR in CBIS, (1) the extent participants use boundary objects, (2) participant skills in terms of collaboration, coordination, and communication, and (3) the diversity of the participating organizations and their goals. Seeking to expand on their findings in terms of new understanding about the influence of significant determinants of CRR in CBIS, this study draws on findings from eight U.S. state and local government public health and criminal justice CBIS cases. This study contributes to existing knowledge about CBIS in the public sector by characterizing the determinants and providing new understanding of the nature of the influence of the determinants of CRR on CBIS. In particular, it shows how the extent of boundary object use, collaboration, and the diversity of participants affect CBIS initiatives in different contexts. In practical terms, creating new understanding of the determinants of CRR has value for public managers and their leadership as they must increasingly collaborate and share information across the boundaries of organizations in the process solving increasingly complex public problems.     

Fake News as a Critical Incident in Journalism

This study examines how American newspapers made sense of the issue of fake news. By analysing newspaper editorials and considering the problem of fake news as a critical incident confronting journalism, this study found that news organizations in the US recognize fake news as a social problem while acknowledging the challenge in defining it. They generally considered fake news as a social media phenomenon thriving on political polarization driven by mostly ideological, but sometimes also financial, motivations. Therefore, they assigned blame for the rise of fake news to the current political environment, to technological platforms Google and Facebook, and to audiences.     

Risk,Regulation, and Rhetorical Boundaries: Claims and Challenges Surrounding a Purported Nuclear Renaissance

This study examines the efforts of individuals and advocacy groups seeking to influence a state utilities commission's decisions regarding a large corporate merger and a nuclear power construction project. Such local engagements have wider significance as the nuclear industry attempts to expand its role in the global energy economy. Utilizing participatory field work and analysis of public documents, we extend the concept of rhetorical boundary work by examining two challenges faced by opponents of the merger and the nuclear project. First, the utilities commission's regulatory mandate is limited to economic risks rather than environmental, health, and safety risks. Second, expert authority is consistently privileged over local, vernacular arguments. We explore the rhetorical negotiation of these boundaries and the effects produced.
