Access to specialists for treatment of behavioral health problems has become restricted in this era of capped budgets and
reductions in Medicare and Medicaid reimbursement. Patients with multiple mental health problems may face additional barriers
to obtaining needed health care services. The study's aim was to measure the impact of behavioral health problems on access
to care and health services utilization for veterans and non-veterans and to determine the contribution of health system characteristics
in the prediction of self-reported health services utilization. The study sample consisted of Vietnam veterans who participated
in both the Vietnam Drug User Study (September 1971 Army discharges) and the Vietnam Era Study (25-year follow-up) (N=642),
as well as a non-veteran cohort (N=197). 相似文献

This article reviews the extensive political and economic literature since 1990 on corruption in Indonesia, Philippines, Thailand, Malaysia and Singapore. After considering each country's individual recent history of corruption, the article comparatively analyses the relationship of corruption in these countries with, respectively, the roles of the state, the private sector and external actors, democratisation and decentralisation, and the impact of corruption on economic growth and inequality. Our conclusion is that while economic liberalisation, democratisation and centralisation of state power influence the forms of corruption and its impact on national economic performance, they are neither necessary nor sufficient for its decline. 相似文献

The short-term viewpoint implicit in high discount rates seems to favour immediate forest exploitation rather than conservation for perpetual benefits. However, the value of logging revenues increases with a lower discount rate, because of the greater weighting given to investible funds. Thus, in several theoretical models, net present value of logging increases as discount rate is lowered. In practice, however, long-term costs of logging may also incur the weighting appropriate to investment funds; reinvestment of logging revenues may not actually take place; and lower discount rates may be appropriate for costs but not revenues. These circumstances favour conservation, the more so at lower discount rates. 相似文献
