Online clustering,fear and uncertainty in Egypt’s transition

Does the uncertainty associated with post-authoritarian transitions cause political and social polarization? Does ubiquitous social media exacerbate these problems and thus make successful democratic transitions less likely? This article examines these questions in the case of Egypt between the 11 February 2011 fall of President Hosni Mubarak and the 3 July 2013 military coup, which overthrew President Mohamed el-Morsi. The analysis is based on a Twitter dataset including 62 million tweets by 7 million unique users. Using a mix of quantitative and qualitative methods, we demonstrate how clusters of users form and evolve over time, the density of interactions between them, and the flow of particular types of information through the clustered network structure. We show that the Egyptian Twitter public developed into increasingly isolated clusters of the like-minded which shared information unevenly. We argue that the growing distance between these clusters encouraged political conflict and facilitated the spread of fear and hatred, which ultimately undermined the democratic transition and won popular support for the military coup.     

Being Underway,Not in Delay,on Climate Change-Related Disclosure

Confusion among companies over what is adequate in environmental disclosure, in general, sets an unfortunate stage for contemplating the newer matter of climate change-related disclosure. Companies waiting for new legislative and regulatory outcomes before contending with climate change disclosure, however, are in exposed and inadvisable delay on the matter. Existing regulations and standards pertain and instruct, if indirectly, on what is to be disclosed and accrued, and when. Their requirements, the possibility of enforcement actions, and recent evidence of costly consequences to former executives from improper environmental financial disclosure reinforce corporate management's need for disclosure diligence, including on climate change. The future is here.     

Climate change adaptation in the Alpine Shire of Australia: a decision process appraisal

This study aims to integrate scientific knowledge from a variety of disciplines with local experience to describe, contextually and in detail, the impact of flood events on the community of the Alpine Shire and current mitigation efforts to alleviate and reduce these impacts. The Myrtleford Floodplain Management Study was the cornerstone of the strategy to address the goal of reducing flood damage in the community. It was found that the most consequential deficiencies in the Myrtleford flood mitigation scheme decision process are related to flaws in four elements of the process: the articulation of goals; the development of appropriate knowledge support; the effectiveness of promotion; and the ability to move from invocation to application. The Alpine Shire can be used as a microcosm that can represent adaptation challenges in other communities to climate change and extreme events. This research contributes to the development of the conceptual and analytical framework of integrated assessments, while making concrete contributions to the development of adaptive policies in Alpine Shire.     

Experimental Methodology in Political Science

Experiments offer a useful methodological tool to examine issuesof importance to political scientists. The historical and culturaldifferences between experiments in behavioral economics andsocial psychology are discussed. Issues of central concern toexperimentalists are covered, including impact versus control,mundane versus experimental realism, internal versus externalvalidity, deception, and laboratory versus field experiments.Advantages and disadvantages of experimentation are summarized.     

Evaluating the Comprehensibility of Jury Instructions: A Method and an Example

Methodological problems in jury simulation research involve issues of sampling, choice of stimulus materials, appropriate unit of analysis, appropriate dependent variable, corroborative data, and problems of role playing. Despite these issues, comprehension of jury instructions may be suitable for examination by jury simulation techniques--if certain of these methodological concerns can be satisfied. In a series of 5 experiments using typical Canadian legal instructions on criminal conspiracy and the coconspirator exception to the hearsay rule, this study attempted to validate a simple and inexpensive technique for testing the incomprehensibility of a given set of jury instructions by requiring participants to apply those legal instructions to a set of facts. The results demonstrate the utility of an application test, and suggest that for assessing the comprehensibility of jury instructions, it may be acceptable to use undergraduate students as participants, to use individual participants without group deliberation, and to employ written stimulus materials.
