全球化与非洲

过去几十年来,在日益加速的全球化过程中,非洲是受益最少的大陆,尤其是撒哈拉以南地区。非洲的历史与其现状有着内在的关联,并值得密切关注。由于非洲各国遭受过长期殖民统治,因此独立后的非洲国家不可能在短期内拥有完善的民主和繁荣的经济。在日益全球化的今天,只有西方跨国公司从中获利,而非洲国家却身处难以扭转的劣势。在这种情况下,南南合作是非常必要的,其最终目标就是要尽力摆脱工业富国的掌控。     

Beyond “Nonsense on stilts”: Towards conceptual clarity and resolution of conflicting economic rights

Many of the debates concerning the existence of economic rights obfuscate the meaning of the possession of a right to an economic good. In order to provide clarification, several theoretical questions must be probed. This essay explores each of these issues in order to demonstrate that greater conceptual clarity repudiates the arguments against the existence of economic rights. It also seeks to attenuate the vexing problem of necessary and painful tradeoffs between competing rights claims. The final portion of this essay heuristically demonstrates how greater conceptual clarity can aid us in dealing with complex policy issues involving competing rights claims. The phase “Nonsense on stilts” is borrowed from Jeremy Bentham’s refutation pf “Natural” rights. Jeremy Bentham, “Anarchical Fallacies” in Human Rights, ed. A.I.Melden (Belmont, CA: Wadsworth, 1970), 30–31.     

A porous humanitarian shield: The laws of war,the red cross,and the killing of civilians

An important literature examines the attempts by the international community in inducing or coercing conflict parties in civil wars to refrain from committing atrocities against the civilian population. We examine in this article whether a non-governmental actor, the distinctively neutral and independent International Committee of the Red Cross, whose mission includes the promotion of humanitarian law and the protection of the civilian population, has such a restraining effect on the conflict parties. Our results suggest that the more time has passed since the ratification of the relevant Geneva Conventions and Protocols, the larger is the risk of civilian victimization. We cannot find evidence that the ICRC’s presence in conflict zones and the seminars it conducts to spread humanitarian law make a crucial difference. Case studies of Bosnia and Darfur indicate that shaming strategies and thus a relatively unusual instrument for the traditionally neutral actor did not abate the killings; the statistical evidence in the form of Granger causality tests rather show that the killing and harming precedes the naming and shaming.     

The effect of imprisonment on recommitment: an analysis using exact,coarsened exact,and radius matching with the propensity score

Objectives

This study examines the effect of prison versus community sanctions on recommitment to prison and compares two levels of community supervision, community control (house arrest) and probation, evaluating whether the findings are contingent on the type of matching methods used in the analysis.

Methods

Logistic regression was conducted on unmatched and matched samples. Exact, coarsened exact, and radius-matching procedures were used to create a selection on observables design. Matching variables included current offense, demographics, criminal history, supervision violations, and a rich set of Florida Sentencing Guidelines information culled from an official scoring sheet. Florida judges use this instrument to sentence offenders within the framework of the state determinate sentencing system.

Results

The results show that with exact matching, there is no effect of imprisonment on recommitment, while the other procedures suggest a specific deterrent effect of imprisonment. All four analysis methods showed that offenders under community control are more likely to reoffend than those under normal probation. Analyses between the matched and unmatched prison observations demonstrate that the matched set of prisoners is composed of offenders who have less extensive criminal records and less serious conviction offenses than unmatched offenders regardless of the matching algorithm.

Conclusions

Contrary to a prior analysis of these data, which found a criminogenic effect of prison, a null effect was found using exact matching. Comparing the matching procedures, the more precise the match the less likely there was an effect of prison. However, community control was criminogenic regardless of the matching procedure.
