“一带一路”倡议下的中非海上安全合作

随着中国"一带一路"倡议的提出与推进,其涉及范围逐步向非洲大陆扩展,特别是习近平主席最终确定将"21世纪海上丝绸之路"穿越非洲大陆。在此背景下,中国政府有必要借助"2l世纪海上丝绸之路"扩展到非洲的机遇,在现有中非经贸、政治及安全合作的基础上把中非关系扩展到海洋领域。鉴于非洲多国政局并不稳定、非传统安全威胁加重,其中来自海上的非传统安全问题日渐突出等局面,在依托"2l世纪海上丝绸之路"扩展中非合作关系的过程中,中国需要与非洲相关国家加强各领域特别是海上的安全合作,并争取其他域外大国的良性参与,避免恶性竞争,共同创建一个"中非海上安全共同体",为包括中国、其他域外国家在内的各国在非洲经贸领域的合作及发展保驾护航。这样既能巩固和加强中非传统合作关系,推动其发展到新的层次,更好地保护中国在非洲的海外利益,也能避免与其他域外大国在非洲走向"零和博弈"。     

Land reforms and voluntary resettlement: household participation and attrition rates in Malawi

ABSTRACT

This paper examines the factors influencing household participation in and withdrawal from a World Bank-funded voluntary resettlement scheme moving 15,000 low-income farming households within and across rural districts in Malawi. Using a survey of 203 beneficiary households, focus groups and in-depth interviews, we identify a lack of access to land and conflict over land in the area of origin as salient participation factors in resettlement, while withdrawal factors include lower access to infrastructure and poor soil quality in resettlement areas. We also highlight limited prior awareness of actual conditions in resettlement areas, low and biased participation in the decision to move, a greater desire for formal land titles due to loss of customary entitlement as a result of resettlement, and widespread ambiguity and confusion over titles for resettled plots. In this context, we point to a pattern of ‘negative resettlement’, in which households remain resettled despite major grievances, for lack of an alternative option, contrasting with ‘positive resettlement’, where households remain by choice. We suggest that intra-district resettlement is more likely to be successful than inter-district resettlement when there is a risk of informed consent deficiency. These findings point to the relative failures of this particular resettlement scheme, and suggest possible improvements for land redistribution schemes from agro-industrial projects to poor households.     

基于SNA视角的政府投资项目合谋关系研究

政府投资项目中腐败案件和工程事故的背后往往存在着合谋问题,合谋主体之间通过社会关系网结成合谋网络。本文从社会网络视角研究合谋关系结构特征,以上海"11.15"大火为例通过SNA分析政府投资项目中各利益主体之间的合谋关系及其利益关系。研究表明合谋关系网与利益关系网之间存在不一致性,合谋关系网中建设单位与总承包单位居于核心位置,合谋网络呈现多个中心性质。在结构洞位置,关键中间人通过收取建桥费获得高额合谋收益,而其他结构洞位置行为人通过收取过桥费获得合谋收益。合谋网络的核心结构行为人具有跨项目合谋特性,而其他行为人合谋具有单个项目性质。本文实现了微观具体主体行为与宏观关系网络相结合,拓展了社会网络分析方法在合谋领域的应用,丰富了对合谋关系的认识,强调在治理合谋问题时在关注合谋利益的同时,应关注关系网络。     

公共政策与社会政策：一个系统论的比较

公共政策与社会政策是多学科的交叉研究领域,二者行动主体和作用客体是存在差异的。公共政策的主体更多的是社会权威机构,以政府和利益集团为核心进行政策制定和决策分析;社会政策的主体是以政府为先导,更加依靠非政府的民间组织发挥政策制定和实施的功能。公共政策偏重权威资源的调配,其制定和决策更多是从宏观层面、整体布局上解决问题;而社会政策由于有社会民间组织的积极参与,使得它有可能关注具体而微的个体生活困境,直接面向需要解决困难的社会成员。

The Frye hearing in Florida: an attempt to exclude scientific evidence

State Supreme Courts require a minimum threshold of reliability and acceptance in the scientific community for all medical and similar evidence to be admitted at trial. In Florida and some other states, the courts adhere to what is known as the Frye standard, whereas in most states and in Federal Courts, it is the so-called Daubert standard. The jurisdiction of the present case is Hillsborough County (Tampa), Florida. Forensic pathologists seldom, if ever, are requested to participate in such hearings, unlike their toxicological and basic science colleagues who are more involved in research methodology and technical procedures. The burden is on the proponent of the evidence to prove the general acceptance of both the underlying scientific principle of the test and procedures used to apply that principle to the facts of the case at hand. The trial judge has the sole discretion to determine this question and general acceptance must be established by a preponderance of the evidence. The authors describe in detail a hearing in a case in which they were all involved. One author (WQS) had researched and documented the original scientific methodology in the literature. The situation involved a car and tractor trailer crash with the two occupants of the car dying of multiple trauma, whereas the truck driver was not injured. Autopsy of the auto driver revealed multiple injuries with exsanguination, and only vitreous humor and liver tissue, but not blood, were tested for ethyl alcohol. The estate of the driver of the automobile brought suit against the owner of the trucking company for wrongful death. The plaintiff requested a Frye hearing to question the reliability of testing other body specimens to translate to probable blood alcohol level. The testimony, submitted documents, and eventual decision by the judge are discussed.     

Methamphetamine-related fatalities in forensic autopsy during 5 years in the southern half of Osaka city and surrounding areas

To outline the recent features of methamphetamine-related fatalities from the medico-legal point of view, a retrospective investigation of forensic autopsy cases involving methamphetamine during a 5-year period (1994-1998) in the southern half of Osaka city and surrounding areas (about 1.57 million population) was undertaken. Among 646 autopsy cases, methamphetamine was detected in 15 victims (nine males, six females; 16-71 years of age; most frequently in males in their thirties). Primary scenes of fatal events were concentrated in the middle of the city. About half of them were transferred from emergency medical centers (survival time, up to 30 h). The cause and manner of death were: methamphetamine poisoning (n=4), homicide (n=4), accidental falls and aspiration from drug abuse (n=4), fire death (n=1), myocardial infarction (n=1), and cerebral hemorrhage (n=1) under drug influence. Usually injection scars and fresh puncture sites were found. Blood methamphetamine concentrations were 2.29-17.05 micromol/dl in the fatal poisoning, 0. 44-3.80 micromol/dl in deaths from other extrinsic causes (trauma), and 1.35-2.17 micromol/dl in cardio- and cerebrovascular strokes. Common complications were cardiomyopathy, cerebral perivasculitis and liver cirrhosis/interstitial hepatitis. Fatal and nonfatal methamphetamine poisonings are separately dealt with by the administrative medical examiner's office and in emergency medical centers. Tightly cooperative approaches of clinical and medico-legal experts are required for the effective social and medical management of drug abuse.
