Advanced information and communication technologies and social media (Web 2.0) have significantly shaped every aspect of contemporary society since Kent and Taylor’s (1998) proposal of dialogic principles, which later evolved into dialogic theory of public relations. It is now time to move the theory forward. The special section aims to advance the dialogic theory of public relations by reviewing the scholarship in organization-public dialogue to pinpoint critical issues for its development and introducing studies that take the dialogue approach to examine a range of public relations practices in China. In this introduction, we first identify critical issues to be addressed for the development of the dialogic theory of public relations and then introduce the articles included in the section. We conclude by proposing research directions for the theoretical and practical development of the dialogic approach to public relations.  相似文献

Abstract

Nudge theory describes how indirect suggestions and positive reinforcement can influence decision-making. We used nudge theory to implement a traffic-light labeling and choice architecture (modifying product placement) intervention at Harvard University cafeterias, but found no significant change in sales. Survey and focus group data showed that some students thought the labeling may exacerbate eating disorders, however, there is extremely limited research on potential negative consequences of labeling. One way to describe these findings is through 20th century philosopher Michel Foucault’s concept of biopower. Biopower manipulates cultural norms and nudges individuals to engage in self-surveillance and self-discipline, de facto subjugating themselves to certain ways of being. Biopower may lead to the creation of an in-group and an out-group based on who can adopt the new behaviors, such as healthy eating. Those in the out-group may face additional unintended consequences, highlighting the need for mixed-methods research to better evaluate public health interventions.  相似文献

A need exists to better understand how racial/ethnic minority students' critical consciousness development in response to marginalization may be involved in their educational and career development. We therefore examined the link between critical consciousness development and career decision self-efficacy and career outcome expectations among racial/ethnic minority community college students. Following social cognitive career theory's conceptual pillars, we developed a testable model integrating critical consciousness and social cognitive variables. This model was tested with 135 racially and ethnically diverse community college students. Data analysis included path analyses and tests of model fit using structural equation modeling. Results suggested that (a) higher critical agency is linked to higher career decision self-efficacy and outcome expectations and (b) critical action and reflection have a bidirectional link and predict higher critical agency. Implications for research and practice aiming to close educational and career gaps among racial/ethnic minorities are discussed.  相似文献

The presence of strategic attackers has become an important factor in the security and protection of systems, especially since the 9/11/2001 attacks, and considerable efforts have been dedicated to its study. When defending against the strategic attacker, many existing studies assume that the attacker would seek to minimize the defender's utility, which implies that the defender and attacker have symmetric utilities. However, the attacker's objective is determined by its own valuation of the system and target of the attack, which is not necessarily consistent with the defender's utility. If the attacker unexpectedly targets a different utility, then the defense strategy might no longer be optimal. In particular, the defense strategy could be inferior if the attacker's utility is not known to the defender. This study considers a situation where the defender's utility is the system survivability and the attacker's utility is the expected number of destroyed elements in the system. We investigate possible attack strategies under these two different utilities and compare (a) the conservative defense strategy when the attack utility is unknown to the defender with (b) the optimal defense strategy when the attack utility is known to the defender. We show that the conservative protection strategy is still optimal under asymmetric utilities when the contest intensity is smaller than one.  相似文献

Abstract

In this article we develop the minimax estimation approach of general linear models to the semiparametric linear models when the parameters are simultaneously constrained by an ellipsoid and linear restrictions. Combining sample information and prior constraints the minimax estimator is obtained and compared with partially least square estimator by theoretical and simulation methods.  相似文献

With the recent increase in social work leadership literature, a few issues in research and practice have come to light. Social work research employs leadership theory derived from military leadership principles adjusted for application in corporate entities, which have decidedly different goals and processes than social work organisations. These models may be influencing the methods of social work leadership research such that study outcomes reflect business-based rather than human service processes and goals. A dearth of leadership education in social work schools and in professional social work settings contributes to a paucity of social workers in upper level administrative roles. A systematic theoretical literature review on social work leadership is conducted in order to generate a working definition of social work leadership and a series of multi-level social work leadership principles. Implications for future research and practice are discussed.  相似文献

While social media like Twitter have been increasingly adopted by public-sector organizations, it remains less explored as to how government and emergency management (EM) organizations use these platforms to communicate with the public in response to emerging natural disasters. Extending the Situational Crisis Communication Theory (SCCT) to the realm of social media, this study examines the emerging semantic networks from 67 government and EM organizations’ official tweets during Hurricane Harvey over a three-week period. It identifies how multiple crisis response strategies—including instructing information, adjusting information, and bolstering—are constituted of different issues, actions, and organizational actors before, during, and immediately after the disaster event. Results suggest that government agencies use the strategy of instructing information predominantly before and during the disaster, whereas adjusting information and bolstering strategies are utilized more during post-disaster recovery. The study offers theoretical and practical implications of using a semantic network approach to studying organizational crisis responses.  相似文献

Soldiers operate under conditions of extreme uncertainty and danger, in which sensemaking is both crucial and challenging. A grounded theory analysis of four epic war novels by veterans (Tolstoy, Remarque, Heller, O’Brien) provides insights into soldiers' sensemaking in combat. The findings are of theoretical and methodological relevance. Theoretically, this article contributes to sensemaking theory by identifying alternative sensemaking pathways besides the traditional enactment-selection-retention model. Additionally, while existing literature suggests that sensemaking failures result in organizational breakdown, this study shows that personnel may continue to do their work in the (fictional) belief that other organizational members can still make sense of the situation. Finally, methodologically, this article introduces grounded theory as a systematic approach to analyzing novels in contrast to current heterogeneous uses of literary fiction in organization and management studies.  相似文献

We study interdependent risks in security, and shed light on the economic and policy implications of increasing security interdependence in presence of reactive attackers. We investigate the impact of potential public policy arrangements on the security of a group of interdependent organizations, namely, airports. Focusing on security expenditures and costs to society, as assessed by a social planner, to individual airports and to attackers, we first develop a game-theoretic framework, and derive explicit Nash equilibrium and socially optimal solutions in the airports network. We then conduct numerical experiments mirroring real-world cyber scenarios, to assess how a change in interdependence impact the airports' security expenditures, the overall expected costs to society, and the fairness of security financing. Our study provides insights on the economic and policy implications for the United States, Europe, and Asia.  相似文献

政府购买公共服务关系到政府职能的转变和政府治理水平的提升,关系到政府与市场之间功能与地位的调整与理顺,因而是国家治理体系的重要一环。政府购买公共服务背后体现的是国家治理体系现代化的取向,那么在理论逻辑上是要以新公共管理理论、政府治理、第三方治理和多中心治理理论为理论基石。目前,我国政府购买公共服务还存在着范围不清、关系不顺、法律不健全的制度现实,因而必须构建科学规范的现代化的政府购买服务制度和配套制度体系,以进一步推进国家治理体系的制度现代化。  相似文献
