Results demonstrated that yield- and profit-maximizing N rates can be different, and the yield- and profit-maximizing

N rates across different across the soil types/landscapes. The profit-maximizing N rate was sensitive to the price of N and the price of switchgrass across all soil types/landscapes, but sensitivity to price changes were not equal for all soil types/landscapes. Published by Elsevier Ltd.”
“Background: Although shopping behavior among adolescents is normal, for some, the shopping becomes problematic. An assessment of adolescent shopping behavior along a continuum of severity and its relationship to other behaviors and health issues is incompletely understood.\n\nMethods: A large sample of high school students (n = 3999) was examined using a self-report survey with 153 questions concerning demographic characteristics, shopping behaviors, other health

Selleck JNK-IN-8 behaviors including Galardin manufacturer substance use, and functioning variables such as grades and violent behavior.\n\nResults: The overall prevalence of problem shopping was 3.5% (95% CI, 2.93-4.07). Regular smoking, marijuana and other drug use, sadness and hopelessness, and antisocial behaviors (e.g., fighting, carrying weapons) were associated with problem shopping behavior in both boys and girls. Heavy alcohol use was significantly associated with problem shopping only in girls.\n\nConclusion: Problem shopping appears fairly common among high school students and is associated with symptoms of depression and a range of potentially addictive and antisocial behaviors. Significant distress and diminished behavioral control suggest that excessive shopping may often have significant associated morbidity.

Additional research is needed to develop specific prevention and treatment strategies for adolescents who report problems with shopping. (C) 2011 Elsevier Inc. All rights reserved.”
“While many consumer surveys show very positive attitudes towards renewable energy, the share of consumers https://www.selleckchem.com/products/3-methyladenine.html actually purchasing green electricity is still in the single-digit percent range in most countries. What can be done to help consumers with positive attitudes towards green electricity to “walk the talk”, i.e. to behave consistently with their preferences? We developed a psychological model based on the theory of planned behaviour (TPB) to design a large-scale behavioural intervention survey with 1163 Swiss electricity consumers. Our results show that by providing information targeted at the key factors influencing the intention to purchase green electricity, namely attitudes towards purchase, social norms and perceived behavioural control, a significant increase in green electricity market share can be achieved. Our results show that price is not the only barrier to purchasing green electricity, and that information to increase the perceived benefit of buying green electricity as well as targeted communication to overcome inertia among retail electricity consumers are equally important factors.
