Categorical attribute based centrality: E–I and G–F centrality

In a paper examining informal networks and organizational crisis, Krackhardt and Stern (1988) proposed a measure assessing the extent to which relations in a network were internal to a group as opposed to external. They called their measure the E–I index. The measure is now in wide use and is implemented in standard network packages such as UCINET ( Borgatti et al., 2002). The measure is based on a partition-based degree centrality measure and as such can be extended to other centrality measures and group level data. We explore extensions to closeness, betweenness and eigenvector centrality, and show how to apply the technique to sets of subgroups that do not form a partition. In addition, the extension to betweenness suggests a linkage to the Gould and Fernandez brokerage measures, which we explore.     

Are we there yet? En route to professionalism

The debate on the professional status of Communication Management/Public relations¹ has been high on the worldwide agenda for decades. While previous research has focused on the criteria for professionalism in this field, practitioners and academics often question the efforts of professional associations to adequately address the issue of implementing systems to facilitate professional status. The emergence of the Global Alliance for Public Relations and Communication Management (GA) as an umbrella body for various regional professional associations, as well as the increased emphasis on regulation, standards and governance in all spheres of the global business environment, have led to renewed questions about global efforts to achieve professional status for this field. This study focused on the goals and actions of member associations of the GA in relation to the question of professional status. In order to understand the current state of affairs an exploratory qualitative approach was followed in which member associations were surveyed and their websites reviewed. The fact that fewer than half of the 27 member associations responded to the survey suggests that a study about this matter is not deemed particularly important and/or that the issue of professional status is not widely pursued. However, the associations that participated in this study agree that professional status is important. The study has also found that many similarities exist across continents in terms of the mechanisms utilized to achieve professional status. Codes of ethics, contributions to a body of the knowledge and the provision of professional training opportunities are regarded as quite important while divergent viewpoints exist in relation to issues like accreditation and a standardized tertiary curriculum.     

Hooray for Hollywood? The 2011 Golden Globes and Ricky Gervais’ image repair strategies

British comedian Ricky Gervais created a media stir as host of the 2011 Golden Globes Awards ceremony by using what many celebrities in attendance and people in the television audience saw as harsh, mean-spirited jokes about the awards, guests, and nominees. Four days after the show, Gervais tried to respond to the backlash by appearing on Piers Morgan Tonight to defend his performance and to repair his image. Gervais employed a variety of image repair strategies: denial, evasion of responsibility, minimization, and mortification. He focused most attention on transcendence, inviting his audience to view the awards show and his performance as an artistic pursuit of truth and self-discovery. Ultimately, Gervais failed to adapt to his audience and failed to repair his image.     

洒风：自虐/露营/腐败

驴路对于洒风来说,最好玩的经历恐怕就是探洞了。洒风说,探洞的刺激在于黑暗、幽闭给人的紧张和恐惧感远远大于人对洞穴奇形怪状风光的好奇心。要克服自身对未知世界的恐惧和种种不安。这是一种挑战,你永远不知道下一步会看见什么,会发现什么,这也正是探洞的魅力所在。
