Scattering is deened on compact manifolds with boundary which are equipped with an asymptotically hyperbolic metric, g: A model form is established for such metrics close to the boundary. It is shown that the scattering matrix at energy exists and is a pseudo-diierential operator of order 2 + 1 ? dim X: The symbol of the scattering matrix is then used to show that except for a discrete set of e...

OBJECTIVE To test the hypothesis that economic recessions lead to reduced global development assistance for health (DAH). METHODS Data obtained from the Creditor Reporting System of the Organisation for Economic Co-operation and Development (OECD) for 15 OECD countries were used to model the percentage change (relative difference) in commitments and disbursements for DAH as a function of thre...

This paper discusses methods to handle changes in establishment-based sampling units that can have a large and possibly erroneous influence on estimates. Changes can be in classification, size, constituency of the sampling unit, or business operation. Methods used to correct the problem depend on when the change occurs and when knowledge of the additional information is gained, the magnitude of...

This article presents data on health care spending for 30 OECD countries from OECD Health Data 2003, the latest edition of OECD's annual data collection on health systems across industrialized countries. OECD data show health care expenditures as a proportion of gross domestic product at an all-time high, due to both increased expenditures and overall economic slow-down. The article discusses s...

PURPOSE OF THE STUDY Aging successfully entails good physical and cognitive health, as well as ongoing participation in social and productive activity. This study hones in on participation in productive activity, a factor that makes an important contribution to successful aging. One conceptual model of productive activity in later life specifies the antecedents and consequences of productivity....

Recent economic downturns have led many countries to reduce health spending dramatically, with the World Health Organization raising concerns over the effects of this, in particular among the poor and vulnerable. With the provision of appropriate health care, the population of a country could have better health, thus strengthening the nation's human capital, which could contribute to economic g...

In this paper, we offer a new way of exploring relationships between three different dimensions of a business operation, namely the stages of business development, the methods of creativity and the major cultural values. Although separately each of these has gained enormous attention from the management research community, evidenced by a large volume of research studies, few studies have attemp...

In this paper, a multi-product single machine scheduling problem with the possibility of producing defected jobs, is considered. We concern rework in the scheduling environment and propose a mixed-integer programming (MIP) model for the problem.  Based on the philosophy of just-in-time production, minimization of the sum of earliness and tardiness costs is taken into account as the objective fu...
