This paper examines the potential contribution of the fisheries sector to national economic development in Sierra Leone, following the cessation of the recent Ebola virus disease (EVD). The tragic deaths of some 4000 persons, as a direct result of this epidemic, have also been accompanied by serious economic disruption to one of the world’s poorest countries, amounting to a loss of over USD 1 billion (20 per cent of annual Gross Domestic Product, GDP). Based on recent work undertaken by the New Partnership for Africa’s Development (NEPAD), an assessment was made of the potential contribution of one of the country’s major natural resource sectors—fisheries—to future economic recovery. It was confirmed that the fish resources of Sierra Leone have an estimated capitalised economic value of USD 735 million, and could potentially make an increased contribution to GDP under suitable conditions, over and above the current estimated level of 10 per cent. However, our results also show that with an overall “readiness assessment” score of 41/100, the sector is unlikely to realise its full potential unless a number of specific areas are addressed (based on analysis valid up to January 2016). These include an improvement in fisheries economic assessment, the upgrading of the fisheries governance and management framework, and the establishment of a fisheries development strategy and implementation plan to channel future investments and interventions in an appropriate sequence. Particular attention should be given early on to an increase in the quality and capacity of both public and private sector organisations relevant to roles and functions within a general process of fisheries sector reform. Finally, the fisheries policy evaluation approach used here is novel. While it has been applied to Sierra Leone for the intrinsic interest of that case, this demonstration also shows that it could be applied elsewhere in the future when reviewing fisheries policy.

本文原题为'Redrawing Local Boundaries:Deriving the Principles for Politically Just Procedures',选自约翰·麦里格莱纳(John Meligrana)主编的《地方政府边界重划:政治、程序与决策的国际研究》(Redrawing Local Government Boundaries:An International Study of Politics,Procedures and Decisions,University of British Columbia Press,2004)。罗南·帕迪森(ronan Paddison)现任英国格拉斯哥大学地理系教授、高级荣誉研究员,曾任《城市研究》(Urban Studies)、《空间与政治》(Space and Polity)等国际人文地理、城市治理研究主流期刊主编,长期从事区域城市治理与地方政府规划研究,在多中心城市治理、社会政策以及城市政治变迁领域造诣颇深。从政治地理学与市政管理学角度来看,地方政府边界重划及市政辖域分并调整,其实质为城市空间和区域资源在特定行政结构、发展结构、财政结构背景下的再次组合排列。因此,地方政府治理与城市治理在关注相关改革动因与管理技术的同时,不应忽视地方政府边界重划的公正程序与公共原则。在本文中,帕迪森教授通过审视地方政府边界性质以及地方政府边界重划所涉问题,指出重新建构更为适当的地方政府边界应遵循三项主张。具体而言,地方政府边界重划应反映地方相关主体的偏好和需要,应具有公平的、透明的和相对较易实现的程序,还应包容不同层级精英的合理利益诉求。

AIM: To evaluate the association between various lifestyle factors and achalasia ***: A population-based case-control study was conducted in Northern Ireland, including n = 151 achalasia cases and n = 117 age- and sexmatched controls. Lifestyle factors were assessed via a face-to-face structured interview. The association between achalasia and lifestyle factors was assessed by unconditional logistic regression, to produce odds ratios(OR) and 95% confidence interval(CI).RESULTS: Individuals who had low-class occupations were at the highest risk of achalasia(OR = 1.88, 95%CI: 1.02-3.45), inferring that high-class occupation holders have a reduced risk of achalasia. A history of foreign travel, a lifestyle factor linked to upper socioeconomic class, was also associated with a reduced risk of achalasia(OR = 0.59, 95%CI: 0.35-0.99). Smoking and alcohol consumption carried significantly reduced risks of achalasia, even after adjustment for socio-economic status. The presence of pets in the house was associated with a two-fold increased risk of achalasia(OR = 2.00, 95%CI: 1.17-3.42). Nochildhood household factors were associated with achalasia ***: Achalasia is a disease of inequality, and individuals from low socio-economic backgrounds are at highest risk. This does not appear to be due to corresponding alcohol and smoking behaviours. An observed positive association between pet ownership and achalasia risk suggests an interaction between endotoxin and viral infection exposure in achalasia aetiology.
