The failure of forestry to contribute to poverty reduction in Central America is due to public policies which inhibit its profitability. Absence of public regulation of harvesting and competing subsidies to agriculture keep forestry stumpage prices artificially low. This encourages destruction of the forest resource, which damages both the environment and the potential to reduce poverty. A comparison of Costa Rica and Honduras reveals two dissimilar approaches toward forest policy. While Costa Rica attempts to raise producer and grower stumpage prices by tax credits, soft loans and differential species fees, Honduras enforces price ceilings and uses centralized authority to control forest production and export. Both countries exhibit weaknesses in the management control cycle of programming, budgeting, implementing and evaluating their forest policies. Yet the Costa Rican approach has increased stumpage prices already, which bodes well for their forest sector. By contrast, the major beneficiary of Honduran forest policy has been COHDEFOR, the state enterprise responsible for forestry management, controlling production, and running its national system of agroforestry cooperatives. Despite greater public authority and resources than the Costa Rican forest service (DGF), the Honduran forest policy is not likely to increase producer profitability or reduce poverty in the near future.  相似文献

This article investigates the effect of Computer Assisted Monitoring of Offenders (CAMO) on probation outcome. In a comparison sample, the effect of CAMO treatment is compared to the effect of “regular” probation. In addition to testing the effects of CAMO as an intermediate treatment, methodological issues, such as level of probation restrictiveness and the effects of prior criminal involvement on probation outcome, are tested. Although the results are mixed, they indicate that level of probation restrictiveness and prior criminal involvement have a greater effect on probation outcome than does CAMO. These findings have ramifications for researchers comparing CAMO probationers to “regular” probationers and for those comparing different CAMO programs. An earlier version of this paper was presented at the Western Social Science Association’s 1992 annual conference.  相似文献

Here we consider two ways that nanomedicine might be disruptive. First, low-end disruptions that are intrinsically unpredictable but limited in scope, and second, high end disruptions that involve broader societal issues but can be anticipated, allowing opportunity for ethical reflection.  相似文献

"Divide and conquer" is a well-known expression although the literature on distributive negotiation offers little theory in support of this technique. This article develops theory to explain increases or decreases in unity and disunity among negotiation groups comprising multiple parties in organizational settings. Specifically, this study analyzes the negotiations surrounding the purchase of the Seattle Mariners baseball team in 1992 by a group that included Japanese investors. The study identifies reframing as a technique that can be used strategically to create disunity between cooperating parties on the same side in a negotiation. This article also develops a theory about techniques that can enhance unity between cooperating parties and can protect against disunity that may be generated by the opposition. Dividing and unifying techniques are both components of a larger negotiation theory that seeks to evaluate actions designed to affect the degree of unity between parties working together in distributive settings.  相似文献
