The effect of board size on shareholder value: Evidence from bank mergers and acquisitions

This study examines the effect of board size on the economic impact of bank mergers and acquisitions (M&A) in the US. Using a hand-collected dataset of 508 M&A between 2012 and 2018, we find that board size is negatively related to acquirer excess returns. In an additional analysis, we show that large boards have positive value implications for banks that combine the CEO and chairman roles as well as for large banks. Our findings indicate that a “one-size-fits-all” approach to board size is not necessarily in the interests of shareholders; instead, a more flexible and proactive formulation is needed.     

困境与超越：扶贫工作的政治学分析

扶贫开发是国家治理的重要内容，有着丰富的政治意涵，展示着执政党执政、政府治理的基本过程和价值归属。中国的扶贫工作带有着明显的运动式、项目制、压力型的色彩，在取得巨大成效的同时，也有着走向无序化、无效化的风险。以现代国家建设和政党建设的基本理念，构筑多中心的贫困治理格局，建立现代化的扶贫开发的制度体系，走向法治化、制度化、民主化、规范化是扶贫开发的治本之策。     

Assessing social work and nursing students’ intentions to work with dying patients

This study assessed social work and nursing students’ intentions to provide end-of-life care, based on the Theory of Planned Behavior. A total of 181 social work and nursing students completed a questionnaire examining intentions to provide end-of-life care, attitudes, subjective norms, perceived control, death anxiety, subjective knowledge, and sociodemographic characteristics. Students manifested a moderate level of intentions to provide end-of-life care, with nursing students indicating higher levels of intentions than social work students. Multiple regression analyses revealed that attitudes, subjective norms, and previous experience were the main predictors of intentions to provide end-of-life care. Recommendations for academic programs are discussed.     

Israel's military public diplomacy evolution: Historical and conceptual dimensions

This study provides an historical overview of the IDF Spokesperson’s Unit (ISU) from the early years of the State of Israel until 2009. Analyzing five periods during which the ISU played a key role in Israel's public diplomacy, this research sheds light on the challenges the ISU faced in different periods and circumstances and examines how the ISU tried to modify its methods and actions in response to geopolitical changes and media development, albeit not always successfully. The study suggests better understanding the adaptation process by applying a three-layer framework for analysis: the tactical layer, the strategic layer and the perceptional layer. The findings of this work demonstrate that in adapting to new circumstances, the ISU focused mainly on the tactical response level, with the result that it did not undertake any review or debate over the need for deeper perceptional changes in ISU policies.     

A systematic review on the application of dialogue in public relations to information communication technology-based platforms: Comparing English and Chinese contexts

This study aims to systematically analyze and compare studies applying the dialogue approach in public relations to information communication technologies (ICTs) under English and Chinese context. Specifically, we want to investigate the subjects, the adoption of dialogic principles, and the processing of additional valuables of dialogue in selected studies. By identifying 68 relevant peer-reviewed journal articles under English context and 13 under Chinese context, we analyzed different subjects in selected publications, including their research topics, methods, samples and objectives. Moreover, our study also revealed the following results: (1) three dialogic principles were well adopted while the other two were not; (2) public engagement was the most common effect; (3) organizational response was the most common antecedent to dialogue implementation. Future studies are recommended to diversify research methods, topics and relevant technologies. We also call for developing theoretical models for dialogue in public relations and updating dialogic principles and measurements. Based upon the fact that the dialogue approach is less studied under Chinese context, we also offer a path to construct effective and ethical communication between organizations and publics on various ICT-based platforms in Greater China.     

Tornado warning: Understanding the National Weather Service’s communication strategies

This study explores the National Weather Service’s communication through a multi-sited rapid ethnography that extends the fully functioning society theory. National Weather Service field offices do not employ public information officers. Instead, forecasters predict the weather, craft messages, and build relationships with their publics. Scholars have called for public relations research that examines messages, including how crisis communication can help publics cope. Additionally, scholars have noted that all organizations need public relations, even if they do not employ formal public relations personnel. In our study, forecasters emphasized the need to build their publics’ tornado threat awareness and provided strategies to make weather science accessible. Forecasters discussed a variety of message strategies including avoiding fear appeals, humanizing the organization, and visualizing risks. Forecasters also built relationships with active publics through soliciting weather spotters and empowering them to prepare others for severe weather. Overall, findings expand knowledge about how organizations can employ strategic public relations to benefit society, thereby extending fully functioning society theory.     

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.     

Postretirement work and volunteering by poverty groups informed by role theory

This study uses role theory to examine the association between postretirement work and volunteering among retirees and to determine whether this association varies across poverty status. Data came from the 2012 wave of the Health and Retirement Study (HRS). The sample was restricted to respondents of older retirees (N = 6,619). We found that postretirement work positively influenced volunteering. However, poverty can be a risk factor of volunteering among older retirees. The positive effect of post-retirement work was found to be more significant in the near-poverty group. We provide an empirical foundation to help inform volunteer programs for retirees.     

Love thy neighbour: Social identity and public support for humanitarian aid

Humanitarian aid can be contentious. Should finite national resources be sacrificed to serve the needy abroad? Social identity theorists argue that identification with a superordinate group, in this case the larger world community, should increase individual support for policies such as international humanitarian assistance. However, individuals can simultaneously associate with multiple identities. How does the combination of world and national identities affect support for humanitarian assistance? Using cross‐national survey data, we find evidence that support for international humanitarian aid is highest among those with a strong world identity and weak national identity relative to other identity combinations, though even those with a strong world identity and strong national identity can be supportive of aid.     

属性集容量确定的夹挤式测度模式及其推算模型

迄今，为解决多属性偏好关联决策属性集容量判断指数复杂性难题所提出的λ模糊测度模式与k-可加模糊测度模式，以及建构在它们之上的属性集容量确定的推算模型，尚存在着适用性差的技术不足。为此，以平衡容量判断的可操作性和容量推算的准确性为视角，提出了一种新容量测度模式，即关于容量判断与推算的夹挤式测度模式，并在此基础上通过引入决策者较易判断给出的容量序信息构建了相应的容量推算模型。基于数值模拟的对比分析表明：新模式不仅在应用可行性上高于k-可加模糊测度模式，而且从容量推算的准确性上看也明显优于λ模糊测度模式和k-可加模糊测度模式，因而对实际决策具有更强的适用性。
