Description: This article explores the role of social capital. Investments in public libraries in developing countries have been made based on the idea that libraries contribute to societal democratization. Yet scholarly understanding of the relationships between public libraries and democratization is sharply limited. In this article the authors review historical studies of national public library systems that cast doubt on widely held assumptions that a positive relationship necessarily pertains between the establishment of public libraries and democracy. Based on this historical review and on sociological theories of social capital (e.g. Bourdieu 1986), the authors develop a theoretical framework intended to facilitate systematic investigation of the contributions public libraries may make to democracy. Using comparative historical and ethnographic methods, the authors analyze the relationship between public libraries and democratic systems of government in Namibia, Nepal, and Malawi, and find that in all three cases public libraries were established mainly during democratic regimes. However, they were not necessarily established by democratically elected governments directly, but rather because democratic regimes proved to be relatively open to the influence of diasporas and global civil society. The authors only find evidence of public libraries contributing to societal democratization, as the authors conceptualize the process, in Nepal ...

Description: This article discusses a study on civic groups' media strategies in the Trinity River Corridor project. Abstract: This study investigates how leaders of civic groups make decisions about using new and social media versus older forms of media. Drawing from theory and empirical research on the social effects of new media, we focus on whether new media is used in a way that lowers barriers to ordinary citizens' participation in local politics, or else contributes to a "digital divide" between elite and non-elite civic groups. To explore these issues, we conducted interviews with leaders of eight civic groups involved in the Trinity River Corridor development project in Dallas, Texas. We also interviewed local journalists, and analyzed the eight civic groups' Web sites, social media sites, and blogs, as well as blogs that linked to the groups' sites. We find that new and social media were used mainly by organizations that were not directly involved in major political actions, and that for the two groups most directly involved in political actions, the wealthier and more powerful group was better connected to other organizations that did use new and social media. The findings reveal a sharp digital divide between networks of civic ...

Description: This article discusses neural systems supporting avoidance behavior in healthy youths. Active avoidance involving controlling and modifying threatening situations characterizations many forms of clinical pathology, particularly childhood anxiety. Presently our understanding of the neural systems supporting human avoidance is largely based on nonhuman research. Establishing the generality of nonhuman findings to healthy children is a needed first step towards advancing developmental affective neuroscience research on avoidance in childhood anxiety. Accordingly, this investigation examined brain activation patterns to threatening cues that prompted avoidance in healthy youths. During functional magnetic resonance imaging, fifteen youths (ages 9-13) completed a task that alternatively required approach or avoidance behaviors. On each trial either a threatening 'Snake' cue or a 'Reward' cue advanced towards a bank containing earned points. Directional buttons enabled subjects to move cues away from (Avoidance) or towards the bank (Approach). Avoidance cues elicited activation in regions hypothesized to support avoidance in nonhumans (amygdala, insula, striatum and thalamus). Results also highlighted that avoidance response rates were positively correlated with amygdala activation and negatively correlated with insula and anterior cingulate activation. Moreover, increased amygdala activity was associated with decreased insula and anterior cingulate activity. Our results suggest nonhuman neurophysiological research findings on avoidance may ...

Description: This article discusses the effects of a supportive communication training workshop on the verbal behavior of behavior analysts. Abstract: This study evaluated the effectiveness of a workshop designed to train behavior analysts to use supportive verbal behavior during distressing situations. Participants were trained to provide descriptive, empathetic and hopeful statements using instructions, rationales, modeling, roleplay, feedback, and rehearsal. A pre-post design was used to analyze the effects of the training on verbal and non-verbal behaviors of four females during simulation scenarios. Results indicate all four participants provided maximum support statements above pre-training levels during post-training simulation and written assessments. The importance of behavior analysts engaging in supportive behavior, as well as the difficulties involved in measuring constructs such as intent and timing of verbal responses, is discussed.
