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.  相似文献

通过调查问卷和入户访谈的方法,对湖南省常德市安乡县4村100名留守妇女进行实地调研,从留守妇女对社会地位、劳动分工、家内事务和两性性别角色的认知四方面可以看出,新时代农村留守妇女的性别平等意识呈现出有所觉醒却依旧保守的特点。造成这一现象的主要原因是经济发展落后且结构单一、基层行政主体的性别平等意识欠缺、传统性别观念根深蒂固及农村留守妇女自身局限等。只有立足于农村留守妇女的现实境况,建立针对性强的就业保障体系,增强公共政策与管理中的社会性别意识,注重性别平等的文化教育,调动妇女们的主体积极性,使她们从意识层面摆脱传统观念的束缚,才能提高社会生产力,从而推动农村经济和整个社会的和谐与发展。  相似文献

中国特色社会主义制度和治理体系的显著优势是制度自信的基本依据,制度自信是对我国制度体系全面而整体的自信。制度自信与中华民族共同体意识具有内在的逻辑关联,二者相辅相成,互相促进,皆属意识范畴。不同层次的制度各司其职,功能各异,从不同维度发挥着铸牢中华民族共同体意识的功能。制度的有机结合、相得益彰,形成系统优势与整体合力共同促进铸牢中华民族共同体意识。把对中国共产党领导的最大制度优势的认同和自信转化为各族人民铸牢中华民族共同体意识的强大动力,是铸牢中华民族共同体意识的关键所在。以宪法统合共同体意识,加强制度体系中的核心价值观建设,创新和完善制度体系,加强制度整合,提升制度效能,充分发挥不同制度的耦合作用和体系优势,是进一步凝聚制度共识,增进制度自信,从而铸牢中华民族共同体意识的必然要求和重要环节。  相似文献

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.  相似文献

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.  相似文献

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.  相似文献

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.  相似文献

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.  相似文献

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.  相似文献
