Generativity and self-enhancement values in eco-friendly behavioral intentions and environmentally responsible consumption behavior

Abstract: During the past 35 years, academic researchers have been examining the relationship between environmentally responsible consumption behavior and numerous antecedent variables. Because sustainability requires a long-term perspective, the study included generativity, a construct developed by Erikson (1950) and self-enhancement values (Schwartz, 1994) as antecedent variables for environmentally responsible consumption behavior. Generativity refers to individuals' beliefs that their current behavior has consequences that extend into future generations, while self-enhancement refers to values relating to power, wealth, and influence. These variables are related in that generativity requires consideration of others while self-enhancement generally refers to considering only one's self. This suggests that individuals high on generativity ought to be more aware of and concerned about the environment and should modify their behavior accordingly, and those who are high on self-enhancement should be less concerned or willing to change behavior. The results of the study, including French and American respondents, indicate that individuals who score high on generativity are more likely to have eco-friendly intentions and more environmentally responsible consumption behaviors, but generativity interacts with self-enhancement, resulting in an interpretation that is different from that typically found in environmentally related studies. © 2010 Wiley Periodicals, Inc.

Differential Uptake of Carbon Nanoparticles by Plant and Mammalian Cells

Abstract: Consequently, a body of literature over the past decade hasbeen centered on cytotoxicity, genotoxicity, and ecotoxicity ofnanomaterials, pointing to the general understanding thatnanotoxicity is often derived from the physiochemicalproperties of the nanomaterials and their interplay with thehost environment.

Characterization of Methanococcus maripaludis sp. nov., a new methanogen isolated from salt marsh sediment

Abstract: A predominant methanogenic bacterium was isolated from salt-marsh sediment near Pawley's Island, South Carolina. A habitat-simulating medium with H2:CO2 as substrate was used for enrichment and isolation. The methanogen is strictly anaerobic, weakly-motile, non-sporeforming, Gram negative, and a pleomorphic coccoid-rod averaging 1.2 by 1.6 μm. Colonies are circular, translucent, pale yellow, and have a smooth surface and an entire edge. The organism is a mesophile, growing between 18 and 47°C, with an optimum near 38°C. The pH optimum for growth is 6.8–7.2, and only formate or a mixture of H2 plus CO2 serve as substrates. Seawater (20–70% v/v) is required, but it can be replaced by 15 mM, or greater, magnesium. Optimal growth occurs with 110 mM sodium. Growth rate is stimulated by selenium (10 μM) but organic compounds (acetate, vitamins, amino acids) are neither stimulatory nor required. The methanogen grows well in autotrophic medium with a doubling time of about 2h. Cells are fragile, are lysed by aqueous solutions of low osmolality and by detergents, and the lack muramic acid. The cell wall is a single electron dense layer. The DNA base composition is 33 mol % guanine plus cytosine. Antigenic relationship of cells and the 16S ribosomal RNA catalog indicate that the salt marsh methanogen is a unique species of Methanococcus, for which we propose the name Methanococcus maripaludis sp. nov.
