most of the environmental threates and resources depletion are direct consequences of human behavior, so altering the behavior could decrease environmental problems. in this regard, identification of the effective factors on behavior would be the first step. lake urmia as a public good, needs public contribution to prevent its more deterioration that could have serious impacts on social welfare...

In this paper, we examine models for exploration and consumption of resources. The fundamental feature of the models is the jumpprocess nature of the exploration for and discovery of the resource. Several models have been proposed and analyzed in the literature. Here we provide numerical schemes, convergence properties, and some new models that provide risk-averse policies to avoid depletion of...

Some important consequences of nursing stress are job burnout and withdrawal symptoms manifested as an intention to quit the job. Job burnout is a stress syndrome characterised by emotional exhaustion (depletion of emotional resources), depersonalisation (negative and cynical attitudes towards one’s clients), and a diminished sense of personal accomplishment (the tendency to evaluate oneself ne...

1. The 1994 ICPD Programme of Action recognised among other things the inter-relationships between population, sustained economic growth and sustainable development. As it mentions, demographic factors, combined with poverty and lack of access to resources in some areas, and excessive consumption and wasteful production patterns in others, cause or exacerbate problems of environmental degradati...

the purpose of the present study is to examine the effects of ego depletion on arousal of elite iranian swimmers. the sample comprised elite swimmers invited to the national swimming team as focused and semi focused (36 subjects). the research design was as pre- and post-test—in two phases of ego depletion conditions and the lack of ego depletion conditions in two experimental and control group...

In this paper, a nonlinear mathematical model is proposed and analysed to study the depletion of forestry resources caused by population and population pressure augmented industrialization. It is shown that the equilibrium density of resource biomass decreases as the equilibrium densities of population and industrialization increase. It is found that even if the growth of population (whether in...

The continuous economic and social progress of our country has helped the rapid civil engineering projects. However, relatively improved project creation also many shortcomings, such as waste resources, depletion, pollution natural environment. construction itself is an item. energy consumption high. Due to shortage resources more serious environment ecological problems, public pays attention r...

Individuals frequently exhibit positive illusions about their own abilities, their possibilities to control their environment, and future expectations. The authors propose that positive illusions require resources of self-control, which is considered to be a limited resource similar to energy or strength. Five studies revealed that people with depleted self-regulatory resources indeed exhibited...

The authors review evidence that self-control may consume a limited resource. Exerting self-control may consume self-control strength, reducing the amount of strength available for subsequent self-control efforts. Coping with stress, regulating negative affect, and resisting temptations require self-control, and after such self-control efforts, subsequent attempts at self-control are more likel...
