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

This paper contributes to studies on dynamic capabilities (DCs) by showing that a neglected environmental contingency – i.e. the occurrence of a jolt – shapes the DCs–performance relationship. We focus on high-tech entrepreneurial ventures because these are the firms that jolts affect most; in so doing, we also advance the understanding of DCs in the entrepreneurship field. We argue that, in the aftermath of an environmental jolt, the high-tech entrepreneurial ventures that use internationalization and new product development capabilities to modify their resource configuration and regain environmental fit enjoy better performance. Econometric estimates on a sample of 340 Italian high-tech entrepreneurial ventures confronting the consequences of the global economic crisis that began in 2008 confirm that separately using these two DCs has a positive performance effect. This effect is stronger for relatively smaller ventures. Interestingly, despite synergies should arise from the combined use of the two DCs, we do not detect any superadditive effects. 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

Testing an Integrative Contextual Career Development Model With Adolescents From High‐Poverty Urban Areas 下载免费PDF全文

Variations in the economic recovery rate across the United States have led to even greater chasms that separate the employed, unemployed, and underemployed (DeSilver, 2017 ). Therefore, understanding and supporting the career development of future generations is critical—especially for those who live outside the context of social privilege. The authors examined the applicability of the integrative contextual model of career development (ICM; Lapan, 2004 ) to a sample of 220 adolescents (129 boys, 91 girls) from a high‐poverty urban area. Results indicated that a canonical variate comprising foundational ICM skills (e.g., career exploration, goal setting) predicted a variate composed of ICM outcomes (e.g., self‐efficacy, vocational identity), thus supporting the usefulness of the ICM framework for this population. The skill of setting viable career goals was an especially strong predictor of outcomes. Implications for career counseling with adolescents living in high‐poverty urban areas and directions for future research are discussed. 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
