Structuring the Religion-Environment Connection: Identifying Religious Influences on Environmental Concern and Activism

Abstract: Recent research on the connection between religion and environmental concern and activism has led to divergent conclusions, with some studies finding a negative effect of religious factors, and others finding no influence or a positive effect. Using a conceptual apparatus of structuration theory, we explain how these divergent findings might be reconciled. We examine data from the 1993 General Social Survey to elaborate how religious affiliation, participation, and beliefs influence environmental concern and private and political environmental activism. Estimates from structural equation models are presented to show the sometimes competing direct and indirect effects of religious affiliation, participation, and beliefs on environmental concern and private and political environmental action.

Mutation of the ptsG gene results in increased production of succinate in fermentation of glucose by Escherichia coli.

Abstract: Escherichia coli NZN111 is blocked in the ability to grow fermentatively on glucose but gave rise spontaneously to a mutant that had this ability. The mutant carries out a balanced fermentation of glucose to give approximately 1 mol of succinate, 0. 5 mol of acetate, and 0.5 mol of ethanol per mol of glucose. The causative mutation was mapped to the ptsG gene, which encodes the membrane-bound, glucose-specific permease of the phosphotransferase system, protein EIICB(glc). Replacement of the chromosomal ptsG gene with an insertionally inactivated form also restored growth on glucose and resulted in the same distribution of fermentation products. The physiological characteristics of the spontaneous and null mutants were consistent with loss of function of the ptsG gene product; the mutants possessed greatly reduced glucose phosphotransferase activity and lacked normal glucose repression. Introduction of the null mutant into strains not blocked in the ability to ferment glucose also increased succinate production in those strains. This phenomenon was widespread, occurring in different lineages of E. coli, including E. coli B.

The Impact of Content and Design Elements on Banner Advertising Click-through Rates

Abstract: This study investigates the impact of content and design elements on the click-through rates of banner advertisements using data from 8,725 real banner advertisements. It is one of the first empirical studies to examine banner advertising effectiveness (measured by click-through rates) and also one of the first to examine the differences between business-to-business (B2B) and business-to-consumer (B2C) banner advertisements. Content elements examined include the use of incentives and emotional appeals. Design elements examined include the use of interactivity, color, and animation. Results suggest that content and design elements do not work the same way for B2B and B2C banner advertisements.
