The purpose of this study was to understand the health benefits of line dancing activity in Korean middle-aged women. This study explored how Korean middle-aged women perceive health benefits through lived experiences of line dancing in their leisure time. Three themes emerged related to health benefits: (1) psychological benefit, (2) physical benefit, and (3) social benefit. This finding sugge...

We develop a simple model of labor market participation, human capital degradation, and re-training. We focus on how non-participation, as a distinct state from unemployment and employment, is determined by the welfare system in interaction with labor market conditions and personal characteristics. We provide a tractable framework to analyze how the decisions to exit the labor force and to miti...

T HE old-age and survivors insurance program combines three types of protection for workers and their families-retirement protection for those between the ages of 65 and 75, annuities for those aged 75 or over, and survivor insurance, payable on the death of an insured worker at any age. The retirement test (or work clause) is applicable when the beneficiary is under age 75, both for retirement...

We provide a framework for understanding how disability risk and features of the disability insurance program in the US affect individual consumption and labor supply behavior in an explicit life-cycle setting. We decompose earnings risk into disability shocks (that reduce the ability to work) and shocks to general productivity. We identify structural parameters of the model using indirect infe...

In this survey paper we mainly discuss the results contained in two of our recent articles [2] and [5]. Let {Xt}t≥0 be a continuous-time, symmetric, nearest-neighbour random walk on Zd. For every T > 0 we define the transformed path measure dP̂T = (1/ZT ) exp(HT ) dP, where P is the original one and ZT is the appropriate normalizing constant. The Hamiltonian HT imparts the self-attracting intera...

Traffic offload technology has been attracting attention in recent years due to efforts made to improve revenues and reduce costs by efficiently handling increases in mobile traffic from mobile network operators as a means of reducing operating costs and improving user experiences. Mobile operators can reduce traffic traversing mobile core networks through offload technology and end-users can o...

A mate poacher is an individual who has sexual relations with someone whom the poacher knows is already in a nominally exclusive, long-term relationship. This article reviews research in which participants were asked to rate the likelihood that benefits and costs exclusively associated with poaching would motivate them to attract, respectively, an attached or an unattached individual, assuming ...

software reuse, costbenefit analysis, decision support The field of software reuse is attracting increasing attention from academics and practitioners who recognize the economies to be gained from reducing duplication of software development effort. However, development for reuse requires additional costs that are difficult to justify under a single-project management view. Since reuse benefits...
