Investigators around the world have reported that incidence and mortality rates for non-Hodgkin lymphoma (NHL) increased steadily and substantially over the last five decades of the 20th century. Identifying what changes in the environment or in behavior fueled this epidemic still presents a major challenge for cancer epidemiology. In April 2006, a symposium was held at the Annual Meeting of th...

According to recent studies on animal personalities, the level of behavioral plasticity, which can be viewed as the slope of the behavioral reaction norm, varies among individuals, populations, and species. Still, it is conceptually unclear how the interaction between environmental variation and variation in animal cognition affect the evolution of behavioral plasticity and expression of animal...

today, survival and value creation in organizations depend on creative and innovative thinking as well as understanding and utilization of environmental opportunities. this research attempts to introduce the organization behavioral barriers which affect the development of corporate entrepreneurship. first, with the views of different experts, various behavioral barriers of corporate entrepreneu...

Adaptive phenotypic plasticity is a key component of the ability of organisms to cope with changing environmental conditions. Fish have been shown to exhibit a substantial level of phenotypic plasticity in response to abiotic and biotic factors. In the present study, we investigate the link between environmental sensitivity assessed globally (revealed by phenotypic variation in body weight) and...

This study sought to determine the perspective taken toward understanding adolescent sexual risk behaviors and related biological outcomes (i.e. pregnancy, sexually transmitted diseases) since 1990. We content analyzed 324 abstracts representing observational research published between January 1990 and December 2007 for inclusion of ecological (environmental) factors, level of analysis, sample ...

A fundamental trait found in most organisms is the ability to register, process, and respond to external factors. Although such environmental sensitivity is critical for adapting successfully to contextual conditions, individuals tend to differ in their sensitivity to the environment, with some more sensitive than others. Such differences in environmental sensitivity can be seen across many spe...

variability in morphological traits, phenolic content, and antioxidant activity of 15 populations of iranian ferula species collected from natural habitats in different regions of iran were investigated. total phenolic content (tpc) of fruit extracts varied from 12.77 to 120.72 mg tannic acid per 1g dry weight. total flavonoid of fruits extract varied from 5.45 mg quercetin per 1 g dry weight i...
