in recent years, researchers have become interested in examining the effect of pettlep imagery on motor performance and how pettlep imagery can improve the performance. the aim of this study was to compare the effect of pettlep imagery and balance practice on dynamic balance in the elderly. participants were 42 male elderly in arak city. they were divided into 4 groups based on the scores of dy...
insulin-like growth factor (igf-1) is an anti-apoptosis factor in multiple cell types associated with various cancers. computational methods allow investigating the systems between 50–100 atoms in the frame of quantum mechanics and up to 50,000 atoms with molecular dynamics. since there are specific interactions between the residues, the solvent could play an important role in the stability of ...

this paper studies the dynamic behavior of price elasticity and its effects on the overall profit. although price elasticity has a significant effect on sales, its dynamics have not been examined so far in pricing models. in this paper, a simple pricing model is suggested in which, price elasticity is considered dynamic. the suggested pricing model is concerned with a monopolist that its object...
this paper presents dynamic portfolio model based on the merton's optimal investment-consumption model, which combines dynamic synthetic put option using risk-free and risky assets. this paper is extended version of methodological paper published by yuan yao (2012) cite{26}. because of the long history of the development of foreign financial market, with a variety of financial derivatives, the ...
planning robot trajectory is a complex task that plays a significant role in design and application of robots in task space. the problem is formulated as a trajectory optimization problem which is fundamentally a constrained nonlinear optimization problem. open-loop optimal control method is proposed as an approach for trajectory optimization of cable parallel manipulator for a given two-end-po...
Two influential papers in the tax avoidance literature (Desai and Dharmapala 2006 and Desai et al. 2007) argue that tax avoidance can be used to facilitate managerial rent extraction from shareholders. The most direct large sample empirical evidence in support of this theory comes from Russia, which has a much different regulatory and corporate governance environment than the United States, but...
Shareholder security class action lawsuits are notable firm events in which a group of shareholders allege the intentional misrepresentation or omission of management disclosure. Rogers and Van Buskirk (2009) provide evidence consistent with management disclosure deteriorating after the filing of a lawsuit. In response to the lawsuit and changes in firm disclosure, investors likely demand addit...
One of the most robust relationships in the social sciences is the large positive correlation between health and education, but establishing a causal link remains a substantial challenge. This paper exploits di¤erences in genetic inheritance among children within the same family to estimate the impact of several poor health conditions on academic outcomes. We present evidence of large impacts o...
