Toward a Behavioral Model of “Homegrown” Radicalization Trajectories

This research note presents a dynamic risk assessment model of homegrown terrorists. The model was tested in a study of convicted “homegrown” American terrorism offenders inspired by Al Qaeda's ideology. The New York Police Department model developed by Silber and Bhatt was chosen as the basis for creating a typology of overt and detectable indicators of individual behaviors widely thought to be associated with extremism. Twenty-four specific cues associated with each stage of radicalization were used to code and estimate the sequencing of behaviors and the duration of the average radicalization trajectory. Sixty-eight cases have been analyzed thus far. A decision was made to publish the initial results when it became apparent that the model was an effective tool for the evaluation of terrorist offenders.     

Verbal ability,depression, and anxiety as correlates of interrogative suggestibility in children exposed to life adversities

In the present study, we assess the relationship of verbal ability, depression, and anxiety with interrogative suggestibility (IS) in a sample of children exposed to life adversities and requiring assistance by the governmental social service (n?=?39), as compared with normal controls (n?=?36). The Gudjonsson Suggestibility Scale 2 was administered to participants in a battery including measures of memory capacity, verbal ability, depression, and anxiety. The finding showed that the ‘assisted’ children were significantly more suggestible than the controls with a large effect size for Yield 1 and total suggestibility. In addition, IS was negatively correlated with verbal memory and ability, but not with anxiety and depression. The two groups differed as to their level of total suggestibility after adjusting for verbal ability. Implications of the findings for the forensic assessment of vulnerable subjects are discussed.     

The Constrained Instability of Majority Rule: Experiments on the Robustness of the Uncovered Set

This paper tests this propositionusing a new technique for estimating uncovered sets and a seriesof experiments, including five-player computer-mediated experimentsand 35-player paper-format experiments. The results supportthe theoretic appeal of the uncovered set. Outcomes overwhelminglylie in or near the uncovered set. Furthermore, when preferencesshift, outcomes track the uncovered set. Although outcomes tendto occur within the uncovered set, they are not necessarilystable; majority dominance relationships still produce instability,albeit constrained by the uncovered set.

Latin American environmentalism: Comparative views

This article examines three common generalizations from the literature on Latin American environmentalism. The validity of these generalizations, structured as hypotheses, is tested with four case studies from Costa Rica, Mexico, Venezuela, and Brazil. The first generalization is that tensions arise between international environmentalists principally concerned with wildlands conservation and national environmentalists engaged in a broader array of local and domestic issues including urban environmental quality and access to natural resources. The second is that environmental groups in Latin America are elitist in structure and participant base. The third is that the particular tactics employed by environmentalists will be closely tied to the relative openness of their nation’s political system. Through a cross-disciplinary case study approach we find the first two hypotheses quickly break down upon closer inspection, while the third is supported. We suggest a modified framework for interpreting environmental activism in the region, one that weights the role of the state as well as the competing strategies employed by grassroots, private voluntary, and professionalized environmental groups. Latin American environmentalism is highly diverse, presenting many faces in different time periods and different countries. Developing one general theory of environmentalism in Latin America is impossible, but more specific categorizations of the middle range may be achievable.
