朴素贝叶斯是一种处理分类问题的常用方法,但它的属性条件独立性假设在实际应用中难以成立,导致其分类性能降低。针对这一问题,文章提出了基于改进PCA的朴素贝叶斯分类算法,该算法通过Pearson和Kendall系数计算出属性间的相关性大小,基于主成分分析筛选出新的属性集,使其尽量满足条件独立性假设,并对新数据集进行朴素贝叶斯分类。实验结果表明,该方法有效地提高了分类准确率。  相似文献

To further the understanding of how communication executives make tough calls in times of organizational-public conflict, we use a conjoint analysis to identify key drivers for organizational stance decision-making. This is the first-ever conjoint analysis applied to advancing the contingency theory of strategic conflict management by examining the relative importance of key contingency factors as determined by practitioners with varied individual characteristics. This study investigates: 1) the relevant importance of and dynamics between three key contingency factors (i.e., external threats, organizational characteristics, and dominant coalition characteristics); 2) the influence of individual characteristics (e.g., gender, experience, and personal ethics) in stance decision-making process; and 3) how different types of organizational stances (i.e., general stance, action-based accommodation, and qualified-rhetoric-mixed accommodation) are determined by these contingency factors and individual characteristics in different conflict situations. Results generated among our communication executive participants include: individual characteristics (i.e., gender, ethics and social responsibility, whistleblowing tendencies, and over 20 years in the communications field) are influential for their strategic conflict management decision-making. Implications for refining the contingency theory and unearthing complex public relations decision-making processes via novel statistical techniques are discussed.  相似文献

Scientology’s public relations function is based on research and writing by L. Ron Hubbard, who studied public relations and drafted documents directing Church communication strategies. Hubbard annotated the textbook Effective Public Relations, which was reprinted for Church practitioners. Textual analysis shows Hubbard was particularly interested in redefining key concepts, emphasizing interpersonal communication strategies, and selectively adopting media relations strategies. The findings suggest that he used the annotations to appropriate the text and position himself as a communications expert. Evidence suggests Church communication practitioners continue to follow Hubbard’s recommendations.  相似文献

文章通过对国内"医享网"癌症社区"肺癌圈"中33篇精华帖的叙事分析,探究其中生命故事的主体对自我身份的建构路径及其对生命价值的意义探寻,并尝试性地提出一些反思。研究发现,在自述和他述生命故事中,叙事者在信息寻求过程中改善自我印象,并运用"写作疗法""阅读疗法"和叙事隐喻理解疾病,帮助患者重塑自身角色。通过社群互动,患者形塑了对自身的身份认同,并形成了集体层面的生命价值观。从本研究的结论看,疾病叙事是癌症网络社区患者建构个体身份、形成身份认同的重要途径,叙事或可成为未来增进社会对癌症乃至其他疾病的理解、推进治疗与康复的可行之路。  相似文献

后发企业技术追赶研究逐渐深入到微观认知基础,但关于管理认知如何驱动技术追赶的机制尚未被充分揭示。通过纵向案例研究,揭示了后发企业高管认知与资源编排动态适配以实现技术追赶的过程。研究发现,在追赶阶段,高管分析型认知通过“纵向资源结构化、稳定性重组、联盟撬动”的资源编排方式进行基本技术积累;在转型阶段,高管创造型认知通过“横向资源结构化、丰富性重组、国际撬动”的资源编排方式获得了新兴技术能力;在超越追赶阶段,高管的悖论型认知通过“双向资源结构化、开拓性重组、平台撬动”的资源编排方式实现了行业技术领先。研究结论既从管理认知视角拓展了技术追赶理论,又为后发企业的追赶实践提供了管理启示。  相似文献

A longstanding debate in the strategic decision-making literature has focused on whether top management teams (TMTs) can effectively balance speed and comprehensiveness when making important decisions. In our research, we build on early insights and pivot from considering whether TMTs can engage indecision-making that balances these tensions to focus instead on when certain types of TMTs are able to achieve such balance. We employ a novel configurational analytical approach and a theoretical framework built from role theory to examine the CEO-TMT interface in a new way. In so doing, we are able to identify specific CEO-TMT constellations that support decision-making that is both fast and rigorous. Using a unique primary dataset and an abductive, configurational approach grounded in fuzzy set qualitative comparative analysis (fsQCA), we identify six specific leader-team configurations that each facilitate decision processes characterized by rigorous intra-team debate, meaningful reconciliation of divergent ideas, and fast decision speed (which we describe as strategic decision-making balance). The range of CEO-TMT configurations that emerge from our analyses contribute new theory and findings for the strategic decision-making and interface literatures more broadly, as well as the specific research streams on executive gender, humility, and TMT structure.  相似文献

A significant body of academic work has explored the ways in which hybrid organizations seek to secure external legitimacy. However, there is a more limited understanding of the ways in which organizational units in hybrid organizations seek to acquire internal legitimacy – legitimacy which is conferred by internal stakeholders. This study draws on more than a century of communications in a Dutch cooperative bank to uncover how a major organizational unit enacted distinct discursive strategies to seek internal legitimacy. The paper extends prior work by showing how internal legitimacy work – the efforts to shape, reinforce, or suppress internal legitimacy judgments – in a hybrid organization is a dynamic process whereby an internal unit generates multiple complementary narratives to promote a fit between its own attributes and the legitimacy evaluations by internal audiences. In addition, it shows how internal legitimacy work can promote this fit by attempting to manipulate not only the impressions of the internal unit's attributes, but also its audiences’ understanding of wider cultural norms of the day, on which their legitimacy judgments are based. In this vein, the paper highlights how discursive internal legitimacy work seeks to generate a taken-for-granted organizational position for the internal units concerned.  相似文献

Cooperation and competition are often viewed as incompatible, antagonistic forces, thus are operationalized as two extremes on a continuum. However, they can coexist and even enable each other, thus may be operationalized as orthogonal constructs. We address this contradictory phenomenon by developing a more granular view of the cooperation–competition paradox. Building on interdisciplinary research, we develop a three-dimensional model of relational space (fairness–opportunism, sharing–control, and engagement–rivalry), providing a novel tool with which to investigate the paradoxical interplay between cooperation and competition through eight operationalizable configurations. Using fuzzy-set qualitative comparative analysis (fsQCA), we test our model by assessing how different configurations of interfirm relationships influence the short- and long-term success of a sample of 217 firms. Our findings show that only two of the eight possible relational configurations are associated with firm success, one in both the long and short term, and the other in the short term only.  相似文献

Poor quality of care may have a detrimental effect on access and take-up and can become a serious barrier to the universality of health services. This consideration is of particular interest in view of the fact that health systems in many countries must address a growing public-sector deficit and respond to increasing pressures due to COVID-19 and aging population, among other factors. In line with a rapidly emerging literature, we focus on patient satisfaction as a proxy for quality of health care. Drawing on rich longitudinal and cross-sectional data for Spain and multilevel estimation techniques, we show that in addition to individual level differences, policy levers (such as public health spending and the patient-doctor ratio, in particular) exert a considerable influence on the quality of a health care system. Our results suggest that policymakers seeking to enhance the quality of care should be cautious when compromising the level of health resources, and in particular, health personnel, as a response to economic downturns in a sector that traditionally had insufficient human resources in many countries, which have become even more evident in the light of the current health crisis. Additionally, we provide evidence that the increasing reliance on the private health sector may be indicative of inefficiencies in the public system and/or the existence of features of private insurance which are deemed important by patients.  相似文献

加强和创新基层社会治理是推进社会建设的重要任务。基于积极政府的理论视角,从行动边界、行动特征、与其他治理主体关系、行动目标四个方面对公共部门在基层社会治理中的角色定位展开探讨;从力量吸纳度和行动主动性两个维度出发,将政府在加强和创新基层社会治理中的角色划分为“积极政府”“灭火式政府”“消极政府”和“无力型政府”。通过分析集中整治侵占农村集体资产的案例发现,相关政府行为具有典型的积极政府特征。积极政府是对政府边界问题的良好回应。加强和创新基层社会治理需发挥政府的积极作用;预判治理风险、吸纳治理资源、精细治理策略是其有效实践路径,三者均是积极的政府行为,互为支撑,相互作用,共同构成治理的良性循环;实践中,要坚持源头治理、动员多元主体参与,借助信息化手段,逐步迈向高效能治理。  相似文献
