Background Obesity continues to be a serious public health challenge. Rates are increasing worldwide, with nearly 70% of the US adults overweight or obese, leading to increased clinical and economic burden. While successful approaches for achieving weight loss have been identified, techniques for long-term maintenance of initial weight loss have largely been unsuccessful. Financial incentive in...

The association between religion and violence has raised much interest in both academic and public circles. Yet on the individual level, existing empirical accounts are both sparse and conflicting. Based on previous research which found that religion plays a role in the support of political violence only through the mediation of objective and perceived deprivations, the authors test Conservatio...

The Austral and Neotropical America (ANA) section of the Society for Conservation Biology includes a vast territory with some of the largest relatively pristine ecosystems in the world. With more than 573 million people, the economic growth of the region still depends strongly on natural resource exploitation and still has high rates of environmental degradation and biodiversity loss. A survey ...

In this paper, an Economic Order quantity (E.O.Q) model with unit production cost, time depended holding cost, with-out shortages is formulated and solved. In most real world situation, the objective and constraint function of the decision makers are uncertainty in nature so the coefficients, indices the objective function and constraint goals are imposed here in fuzzy environment The problem i...

The corrosion of metals is a destructive process regarding to the basic modern constructional material with a great importance for the nowadays industry and in many cases represents an enormous economic loss. Therefore, it is not a surprise that the research on the corrosion and corrosion protection of metallic materials is developed on a large scale in different directions and a wide range of ...

The paper revisits the issue of necessary optimality conditions for infinite-horizon optimal control problems. It is proved that the normal form maximum principle holds with an explicitly specified adjoint variable if an appropriate relation between the discount rate, the growth rate of the solution and the growth rate of the objective function is satisfied. The main novelty is that the result ...

Empirical evidence shows that in recessions the rate of workplace accidents goes down. This paper presents a theory and an empirical investigation to explain this phenomenon. The theory is based on the idea that reporting an accident affects the reputation of a worker and raises the probability that he is fired. If the unemployment rate is high, a worker faces a big loss when fired and fewer wo...

In inventory, the utility of the deteriorating items decreases with time. The degree of deterioration of product utility can be treated as penalty cost in the inventory replenishment system. In this paper, we present EOQ model for those perishable products, which do not deteriorate for some period of time and after that time they continuously deteriorate with time and loose their importance. Th...
