Information subsidies and agenda-building during the Israel–Lebanon crisis

This study examined the impact of information subsidies on media coverage during a crisis. Using the July 2006 Israel–Lebanon conflict as a backdrop, this research reviewed access that U.S. military public affairs officers provided the media and analyzed subsequent coverage for the presence of the military's message. Coverage was more neutral to positive than negative. Items containing organizational messages were more positive; those quoting practitioner-facilitated sources introduced organizational messages into coverage and generated more positive coverage. Access to information subsidies had a positive impact on coverage and aided in the successful transfer of attribute salience from practitioners to the media.     

Intercandidate agenda-setting in presidential elections: Issue and attribute agendas in the 2004 campaign

This study examined the role of political public relations in the process of intercandidate agenda-setting. Specifically, a content analysis of news releases, political speeches, and issue platform statements was conducted to assess the salience of issues and attributes in the 2004 presidential election from the Bush, Kerry, and Nader campaigns. While modest evidence for intercandidate agenda-setting associations regarding issue salience was obtained, more robust support was detected for attribute salience relationships. In light of these findings, the theoretical and practical implications for political public relations are discussed.

CHARACTERIZATION OF EFFICIENT SEQUENTIAL SCHEMES FOR POPULATION GROWTH MODELS1

For population growth models, which include standard processes like Poisson, birth, birth-death, immigration-death, simple epidemic and M/M/1 queue as particular cases, we obtain efficient sequential schemes and characterize all efficiently estimable functions of the parameters by first deriving a sequential version of the information inequality.

经济新常态下混合所有制的改革方式与推进要点--基于正和博弈的视域

十八届三中全会以来,混合所有制被视为推动国资国企改革的加速器。而混合所有制并非新提法,党的十四届三中全会就已提出混合经济的思想。文章认为当下重提混合所有制是为了巩固基本经济制度,促进非公有制经济发展,让国民共享经济发展成果。混合所有制不是“国退民进”、或“国进民退”的零和博弈,而是可以实现“国民共进”的正和博弈。在经济新常态的背景下,深化混合所有制改革是不断提高国有经济的活力、控制力、影响力的重要手段,应用正和博弈的思维看待混合所有制改革,采取渐进分类分拆的方式推进混合所有制改革,而改革的关键点在于建立规范化的法人治理结构。     

信息社会背景下的信息自决权

联邦宪法法院在1983年"人口普查案"中创制了"信息自决权",其防御法构想已经无法适应互联网时代信息无处不在的现象. 传统"信息自决权"保护范围过于宽泛,侵犯条件容易满足,这既不符合现实要求,也将导致该领域陷入"法律化陷阱". 改革方案提出保护信息的使用情境,这将导致基本权保护范围大幅缩减. 建议"进化"而非"革命"地重新调整对该基本权的认识,其保护人格权且应当考虑个人"合理的隐私期待",应限制对侵犯的认定. 在私人法律关系中,还应当谨慎运用国家保护义务教义.     

Model Selection Information Criteria in Latent Class Models with Missing Data and Contingency Question

Latent class analysis (LCA) has been found to have important applications in social and behavioral sciences for modeling categorical response variables, and nonresponse is typical when collecting data. In this study, the nonresponse mainly included “contingency questions” and real “missing data.” The primary objective of this research was to evaluate the effects of some potential factors on model selection indices in LCA with nonresponse data.

We simulated missing data with contingency questions and evaluated the accuracy rates of eight information criteria for selecting the correct models. The results showed that the main factors are latent class proportions, conditional probabilities, sample size, the number of items, the missing data rate, and the contingency data rate. Interactions of the conditional probabilities with class proportions, sample size, and the number of items are also significant. From our simulation results, the impact of missing data and contingency questions can be amended by increasing the sample size or the number of items.     

Path to “Stardom” in Globally Distributed Hybrid Teams: An Examination of a Knowledge‐Centered Perspective using Social Network Analysis

Although distributed teams have been researched extensively in information systems and decision science disciplines, a review of the literature suggests that the dominant focus has been on understanding the factors affecting performance at the team level. There has however been an increasing recognition that specific individuals within such teams are often critical to the team's performance. Consequently, existing knowledge about such teams may be enhanced by examining the factors that affect the performance of individual team members. This study attempts to address this need by identifying individuals who emerge as “stars” in globally distributed teams involved in knowledge work such as information systems development (ISD). Specifically, the study takes a knowledge‐centered view in explaining which factors lead to “stardom” in such teams. Further, it adopts a social network approach consistent with the core principles of structural/relational analysis in developing and empirically validating the research model. Data from U.S.–Scandinavia self‐managed “hybrid” teams engaged in systems development were used to deductively test the proposed model. The overall study has several implications for group decision making: (i) the study focuses on stars within distributed teams, who play an important role in shaping group decision making, and emerge as a result of a negotiated/consensual decision making within egalitarian teams; (ii) an examination of emergent stars from the team members’ point of view reflects the collective acceptance and support dimension decision‐making contexts identified in prior literature; (iii) finally, the study suggests that the social network analysis technique using relational data can be a tool for a democratic decision‐making technique within groups.
