Gun Control Policy Preference in Context: A Contextually Sensitive Model of Gun Control Policy Preferences

Using data from the 2000 American National Election Study and the Uniform Crime Reports, this research studies the impact of core values and contextual effects on gun control policy preferences. The research seeks to produce a contextually sensitive model of gun control policy preferences that accounts for the nature of the elite message war regarding the issue of gun control and for both long and short-term contextual factors that might sway individual opinions at the point of stimulus (e.g., the survey question). While the analysis does find conditioning effects, the effects do not conform to the theoretical expectations, and they are generally weaker than expected. In contrast, the research demonstrates the strong connections that formed in the public’s mind between ideological, partisan and gender-based core values and gun control policy preferences. These results are consistent with research that found the effects of political messages often vary in counterintuitive ways due to variance in the strength of the message and political awareness (Zaller 1992). Replicating this research across various time periods permits the investigation of the decay rate of impacts on individual policy preferences created by substantial, one-time contextual effects. It may be that contextual effects have a substantial impact in the short-term, but these short-term impacts are mitigated over the longterm by continual reinforcement of the basic themes employed by elites in the message war surrounding the issue

Paired aluminum sites in zeolite catalysts enhance aromatics production

In this issue of Chem Catalysis, Ruiz-Martínez and co-workers investigate the effect of aluminum (Al) proximity and distribution on acid-catalyzed reactions in zeolites. They find that Al enrichment near the external surface results in paired acid sites that exhibit enhanced activity for aromatics formation

Silica-Based materials as catalysts or supports in solvent-free organic reactions

This chapter summarizes recent developments in solvent-free organic synthesis. In particular, the chapter focuses on the reactions conducted under neat conditions and in the presence of silica-based reagents or catalysts. The chapter describes the synthesis of those materials and salient features that are responsible for the enhanced reaction rates and greater selectivity. The discussion demonstrates that silica-based solids can be used to carry out a wide range of reactions and the approach can prove beneficial, leading to no solvent waste, in line with modern green chemistry metrics

Short Story in an ESL Freshman English Course: Bridging the Gap between language and literature

[EN] In recent years, the place of literature in language teaching has regained its impetus and the prominent role it plays in promoting linguistic, cultural, intellectual and academic benefits has been acknowledged. Nevertheless, the place of literature in language teaching context in Turkey is still approached to be an outside source to be assigned as extensive reading rather than to be a classroom worthy material to be utilized in class. This article describes a literature lesson at a Freshman Englih level and outlines the steps to be taken to implement language based activities to promote ‘language awareness’ and to foster ‘meaning construction’ and ‘cultural awareness’ in a process based classroom setting. The steps also show that ESL Freshman students have much to gain from literature when the text is explored through language based activities without losing the literary nature of literature.Keywords: literature; short story; esl; once upon a time; freshman English; turkeyAvci Vile, DE.
