As natural-resource issues become more complex, particularly in developing-world contexts, there is a growing need for adaptive management solutions. However, the skills necessary to deal with these increasingly complex situations are not always present in many low-income countries. There is also a growing recognition that many capacity-building activities are limited in their effectiveness. This article suggests a problem-based learning (PBL) approach to capacity building. Using the example of training courses developed to help natural-resource management in Guyana, this article illustrates how PBL can help to enhance the capabilities needed for adaptive management.  相似文献

This article reconsiders the negotiations between the United States and Britain at the outbreak of the 1982 Falklands War. The Reagan Administration did not support Britain, its staunchest NATO ally, and on the contrary assumed an even-handed position that recognised Argentina as a key ally as much as Britain. Not only did American mediation fail; it also caused a major crisis in Anglo-American relations. The underlying reason for the American decision was the obsessive importance that the Administration attached to fighting communism in Latin America after establishing covert co-operation with the Argentinian military junta in 1981.  相似文献

This study investigates prolonged kidnappings as a stressful situation and the different coping strategies used to survive it. A 35‐question, semi‐structured interview and an adaptation of the ‘Ways of Coping Checklist’ by Lazarus et al. (1986) were applied to live subjects who had been kidnapped by different Colombian guerrilla groups for periods of time above three months. The results of the interviews and checklist were compared; it was found that to achieve an efficient coping process it is necessary to be versatile with the coping directed to emotions, such as fantasy and self‐guilt, and directed to the problem, such as problem solving. Other topics for future studies are proposed.  相似文献

The article argues that British non-proliferation policies towards the Middle East have had limited success because they are circumscribed by dependence on alliances and constrained by other factors such as Britain's historical legacy, its status as a nuclear weapons state and, especially through the European Union's engagement with the region, the communication of self-interest rather than credible pursuit of the declared objective of regional security-building. Despite promoting and implementing its own disarmament policies, Britain has been unable to overcome mistrust and perceptions of hypocrisy in the region in order to strengthen the non-proliferation regime. This is particularly evident in the dispute with Iran, which is examined in detail with the assistance of Adler's ‘double-damned dilemma’ model. The analysis argues that the Western coercive approach has facilitated the stalemate with Iran, because it has encouraged Iran's provocations and allowed it to respond with a strategy of denial. The analysis suggests that Britain and its allies adopt a defusing strategy which does not reduce the dispute to a proliferation problem, but treats Iran's behaviour as a quest for recognition. Britain has little influence on Iran, but might build on its relationship with Turkey to develop this approach in conjunction with its allies.  相似文献

The use of external policy and management consultants in government has been receiving increasing attention in many countries, including Canada. We explore new data on management consulting compiled from information released since the creation of the Federal Accountability Act to address the supply side of contracting. We find several large multi‐year contracts have taken up a larger percentage of contracting activity while the number of smaller contracts has declined. The data suggest a pattern of oligopsonic demand concentrated mostly in a handful of very heavy users and an increasingly oligopolistic supply pattern where less than 5% of companies accounted for 80% of total contract values and where repeat contracts are the norm. Measures of accountability and transparency need to extend to the “invisible” public service of contract consultants.  相似文献

This paper examines the relationship between parental transfers and post-marital residence of children in rural Ethiopia. We investigate whether asset transfers to children are an avenue which parents use to secure old age. We model post-marital residence and transfers simultaneously in a two-stage probit least squares estimation framework. We find a positive relationship between transfers and post-marital residence, a proxy for old age support. Children who receive more assets are more likely to stay at birth place after marriage and vice versa. In conditions of scarce or lacking social security mechanisms, parents make strategic transfers to ensure better old age.  相似文献

The graphic memoir Notas al pie (2017) written by Argentinian Nacha Vollenweider includes an illustration which reinterprets an image from the Nueva corónica y buen gobierno, a colonial document written by Quechua nobleman Felipe Guamán Poma de Ayala around 1615, when Peru was under Spanish rule. This article argues that if Guamán Poma's image portrays a critique of Western colonial power, Vollenweider's reappropriation follows its aftermath, and targets the structures of coloniality that underpin the formation of both individual and collective identity.  相似文献

Blast trauma results from highly variable events that can lead to similar effects in the skeleton. Clinical literature, which largely focuses on soft tissue, provides limited efficacy for interpreting fully skeletonized cases. Interpretation of skeletal blast trauma is hampered by the low number of fully skeletonized case studies and experimental replication studies, which mainly use nonhuman proxies. The purpose of this study is to discuss fracture patterns on two individuals from WWII as a means to better understand and identify fracture patterns associated with blast trauma. Existing clinical and anthropological criteria are reviewed and applied to two World War II cases, both presumed to exhibit blast trauma based on historical contexts. These case studies exhibit combinations of complicated and extensive signs of blunt-force and projectile trauma, reflecting the diversity of skeletal trauma resulting from blast-related events. This analysis emphasizes the arguably impossible task of establishing a diagnosis based on the available literature and lack of prior knowledge about specific losses. Ultimately, analysts must consider the totality of skeletal trauma, combining biomechanical theory and relevant clinical and anthropological literature to arrive at useful yet defensible assessments of trauma. However, refined criteria and additional studies are needed to assess complicated trauma from blast-related events in anthropological contexts.  相似文献
