This paper illustrates, with a ten year simulation, possible effects of Malaysia's national buffer stock for natural rubber on the level and stability of export earnings, export tax revenue, producer income and world price. Employing rubber market parameters based on inference and empirical tests and buffer stock operating costs and policies similar to those of the current Malaysian buffer stock, it is shown that capital requirements for effective control exceed those at the disposal of the buffer stock manager while control may be expected to stabilize price at the expense of export earnings and producer income stability. These unfavourable effects can be neutralized in part by the increase in receipts obtained with a sufficiently narrow controlled price range or by an increase in demand emanating from reduced price risk. Under the apparent wider range of the buffer stock, losses in export earnings and producer income, as well as capital expenses and the terminal deficit of the stock authority are each less than 1 per cent of export earnings and producer income. The maximum short run capital requirement is about 2.5 per cent of these latter magnitudes. The arguments presented indicate that internationalization of the buffer stock would increase the benefits and decrease the costs in terms of the proportion of producer income and export earnings, compared to the existing national device.  相似文献

Against the background of attempts to explain the poor Corporate social responsibility (CSR) performance of transnational oil corporations in the Niger Delta in the context of flawed approaches, processes and inadequate CSR packages, this paper contests not only the explanations for the failure of CSR, but the core idea that CSR is capable of engendering sustainable community development at all. Given the enormity of the development challenge in the region, corporations cannot, even with the best of intentions, make meaningful impact on host communities, mainly because of the structural constraints arising from the profit-seeking ethos which drives corporate behaviour.  相似文献

In this article , a case of examining an incomplete human skeleton found in a forest is presented. Based on the assessment of posttraumatic lesions in the skull bones, the cause of death of a man who had died 14 years prior to the examination was determined with high probability to be due to a lightning strike. Moreover, the rare pathological lesions within the skeleton, such as a healed fracture of the humerus and rheumatoid malformations within the hand, in reference to preserved medical records, have also allowed to identify the deceased. Most noteworthy points in this case are, however, initially difficult to comprehend, posttraumatic lesions within the bones of the skull such as carbonization and fracture of the vertex. Their origin can be explained by a lightning strike as the most probable cause of death. Thus, the presented case demonstrates probable cause of death and identity can be established many years after death, based on skeletal remains.  相似文献

Observers argue that the business of news is responsible for worsening the coverage of terrorism, but exactly how economic considerations influence coverage is controversial. Based on an analysis of over 1600 articles from The Washington Post and USA Today, we find that concerns about the effects of economic pressures on terrorism reporting are exaggerated. The business climate affects coverage, but the long-term impact of market pressures on coverage is modest. Articles about terrorist violence are increasingly prominent, but coverage of counterterrorism remains robust. Efforts to inoculate the press against the worst excesses of the market are unnecessary.  相似文献

Objectives

The study tests whether participation in interventions offered by a subset of sites from the National Safe Start Promising Approaches for Children Exposed to Violence initiative improved outcomes for children relative to controls.

Methods

The study pools data from the nine Safe Start sites that randomized families to intervention and control groups, using a within-site block randomization strategy based on child age at baseline. Caregiver-reported outcomes, assessed at baseline, 6 and 12 months, included caregiver personal problems, caregiver resource problems, parenting stress, child and caregiver victimization, child trauma symptoms, child behavior problems, and social-emotional competence.

Results

Results revealed no measurable intervention impact in intent-to-treat analyses at either 6- or 12-month post-baseline. In 6-month as-treated analyses, a medium to high intervention dose was associated with improvement on two measures of child social-emotional competence: cooperation and assertion. Overall, there is no reliable evidence of significant site-to-site effect variability, even in the two cases of significant intervention effect.

Conclusions

Since families in both the intervention and control groups received some degree of case management and both groups improved over time, it may be advantageous to explore the potential impacts of crisis and case management separately from mental health interventions. It may be that, on average, children in families whose basic needs are being attended to improve substantially on their own.  相似文献
