The Role of Public Relations in Social Capital

Public relations research has traditionally focused on how public relations efforts make organizations more effective. Recently, scholars have argued for the broader role of public relations in society. That is, how can public relations be used to improve society rather than simply making organizations more effective? Existing studies have emphasized the relationship between internal public relations and organizational social capital. Lack of scholarly attention has been paid to how public relations efforts affect citizens’ social capital in general. To fill the gap in this area, this study examines how different types of public relations efforts contribute to citizens’ social capital. Specifically, this study uses data from the 2010 Pew Internet and American Life Project ‘Social Side of the Internet’ survey to examine the influence of public relations efforts by various organizations in individuals’ social capital. Overall, the analyses suggest that organizations’ face-to-face meetings with their members enhance interpersonal trust and civic engagement, and that organizations’ strategic use of social media boosts civic engagement, whereas strategic communication via email, blogs, and websites decreases civic engagement. This study provides empirical evidence and practical implications for the important role of strategic social media use and interpersonal communication in enhancing social capital

The Role of Public Relations in Social Capital and Civic Engagement

Public relations scholars have increasingly argued for the broader role of public relations and strategic communication in society (e.g., Taylor, 2010). That is, how can knowledge of public relations be used to make society better rather than simply making organizations more effective? This study examines how different types of public relations and strategic communication efforts contribute to citizens’ social capital and civic engagement. Specifically, this study uses data from the 2010 Pew Internet and American Life Project ‘Social Side of the Internet’ survey to examine the relationship between various strategic communication efforts by social, civic, professional, and religious organizations and individuals’ social capital and civic engagement. Overall, the analyses suggest that organizations’ face-to-face meetings with their members foster interpersonal trust and both social-oriented and private-oriented civic engagement, and that organizations’ strategic communication via social media boosts both social-oriented and private-oriented civic engagement, whereas strategic communication via email, blogs and websites decreases social-oriented civic engagement. Theoretical and practical implications of the findings for the larger role of public relations and strategic communication in social capital and civic engagement are discussed

Does Planning and Practice Make Perfect? A Study of Communication Culture, Autonomy and PR Practitioners’ Confidence in Handling Crises

The study builds on research by Marra (1998) who examined crisis communication case studies and found that organizations with crisis plans do not always manage crises well. To assess Marra’s (1998) concept of communication culture, this study looked at organizations’ use of two-way symmetrical communication (Grunig, 1992); PR professionals’ crisis confidence and communication autonomy; and the presence of a crisis plan. An Internet survey of members of the Public Relations Society of America (PRSA) yielded 251 valid responses. Findings revealed that PR professionals who reported they were part of the dominant coalition exhibited more confidence in their organization’s ability, their own ability and their CEO’s ability to handle a crisis. PR professionals who viewed their organizations higher on their use of two-way symmetrical communication (communication culture) displayed more confidence in their organization’s and CEO’s abilities to handle a crisis but not their own. Additionally, PR practitioners who have a crisis plan for the organization and who perceive they are part of the dominant coalition have more confidence in their organization's ability, their own ability, and their CEO’s ability to handle a crisis than those who only had a crisis plan. Research also revealed that PR practitioners who have a crisis plan for the organization and who perceive their organizations higher in their use of two-way symmetrical communication exhibited more confidence in their organization's ability and their CEO’s ability to handle a crisis than those who had only a crisis plan; however, they did not display more confidence in their own ability to handle a crisis

Transcriptional profile of human thymus reveals IGFBP5 is correlated with age-related thymic involution

Thymus is the main immune organ which is responsible for the production of self-tolerant and functional T cells, but it shrinks rapidly with age after birth. Although studies have researched thymus development and involution in mouse, the critical regulators that arise with age in human thymus remain unclear. We collected public human single-cell transcriptomic sequencing (scRNA-seq) datasets containing 350,678 cells from 36 samples, integrated them as a cell atlas of human thymus. Clinical samples were collected and experiments were performed for validation. We found early thymocyte-specific signaling and regulons which played roles in thymocyte migration, proliferation, apoptosis and differentiation. Nevertheless, signaling patterns including number, strength and path completely changed during aging, Transcription factors (FOXC1, MXI1, KLF9, NFIL3) and their target gene, IGFBP5, were resolved and up-regulated in aging thymus and involved in promoting epithelial-mesenchymal transition (EMT), responding to steroid and adipogenesis process of thymic epithelial cell (TECs). Furthermore, we validated that IGFBP5 protein increased at TECs and Hassall’s corpuscle in both human and mouse aging thymus and knockdown of IGFBP5 significantly increased the expression of proliferation-related genes in thymocytes. Collectively, we systematically explored cell-cell communications and regulons of early thymocytes as well as age-related differences in human thymus by using both bioinformatic and experimental verification, indicating IGFBP5 as a functional marker of thymic involution and providing new insights into the mechanisms of thymus involution

Target density effects on charge tansfer of laser-accelerated carbon ions in dense plasma

We report on charge state measurements of laser-accelerated carbon ions in the energy range of several MeV penetrating a dense partially ionized plasma. The plasma was generated by irradiation of a foam target with laser-induced hohlraum radiation in the soft X-ray regime. We used the tri-cellulose acetate (C$_{9}$H$_{16}$O$_{8}$) foam of 2 mg/cm$^{-3}$ density, and $1$-mm interaction length as target material. This kind of plasma is advantageous for high-precision measurements, due to good uniformity and long lifetime compared to the ion pulse length and the interaction duration. The plasma parameters were diagnosed to be T$_{e}$=17 eV and n$_{e}$=4 $\times$ 10$^{20}$ cm$^{-3}$. The average charge states passing through the plasma were observed to be higher than those predicted by the commonly-used semiempirical formula. Through solving the rate equations, we attribute the enhancement to the target density effects which will increase the ionization rates on one hand and reduce the electron capture rates on the other hand. In previsous measurement with partially ionized plasma from gas discharge and z-pinch to laser direct irradiation, no target density effects were ever demonstrated. For the first time, we were able to experimentally prove that target density effects start to play a significant role in plasma near the critical density of Nd-Glass laser radiation. The finding is important for heavy ion beam driven high energy density physics and fast ignitions.Comment: 7 pages, 4 figures, 35 conference

An Angry, Hopeful, or Efficacious Citizen: Information, Emotion, and Participation in an Emerging Democracy

A growing body of research has examined how access to political information via digital media contributes to democratic participation in new or transitory democracies. Much of this work focuses on cognitive factors, such as political efficacy and civic knowledge, while less attention is paid to the role of emotion. Drawing on insights from the orientation–stimuli–orientation–response (O-S-O-R) and anger activism model (AAM), this study proposes and tests a model of political information seeking and participation using a national survey of adult Nigerians ( N   =  600). Findings provide support for the model and highlight potential pathways through which political information may enhance participation
