AbstractThe involvement of small island states (SISs) in a growing number of international organisations (IOs) has placed increased pressure on domestic bureaucracies and political systems. Rapid turnover among SIS leaders, combined with generational change and decreased local support, has amplified disadvantages. Growing complexity has therefore further exposed the long-standing vulnerabilities of SISs. They can play a creative role at the margins, and on certain issues in certain IOs, but in general asymmetries prevail. The lesson is that national sovereignty does not always equal control, and what might superficially appear to be equal access is constrained by the availability of technical expertise to the detriment of SISs. 相似文献

Previous studies documented that crime is heavily concentrated in families. However, many studies relied on relatively small samples, often males and information on criminal involvement was self-reported. The present study investigates: (1) the prevalence of arrests in three generations; (2) the concentration of offenders and arrests within families; (3) the relationships between arrests among the relatives; (4) the relationship between arrests and family violence. A complete cohort of the families in which a child was born in a Dutch city was selected, and the arrests of all known family members (siblings, parents and grandparents) were investigated. Results showed that 7.2 % of the mothers and 18 % of the fathers had been arrested. The likelihood of parental arrests was related to the likelihood of grandparental arrests. There was clear evidence for assortative mating: when the mother was arrested, the likelihood that the father was arrested was increased with a factor five. Maternal arrests were also related to arrests of her parents-in-law. Arrests are heavily concentrated within families, 7.8 % of the families account for 52.3 % of the suspects. Arrests in family members constitute a major risk factor for poor developmental outcomes, such as criminal behavior. At the time of birth, it is possible to use information on arrests to select children who are at relatively high risk for the target of prevention efforts.Implications for prevention policies are discussed. 相似文献

Two person DNA admixtures are frequently encountered in criminal cases and their interpretation can be challenging, particularly if the amount of DNA contributed by both individuals is approximately equal. Due to an inevitable degree of uncertainty in the constituent genotypes, reduced statistical weight is given to the mixture evidence compared to that expected from the constituent single source contributors. The ultimate goal of mixture analysis, then, is to precisely discern the constituent genotypes and here we posit a novel strategy to accomplish this. We hypothesised that LCM-mediated isolation of multiple groups of cells (‘binomial sampling’) from the admixture would create separate cell sub-populations with differing constituent weight ratios. Furthermore we predicted that interpreting the resulting DNA profiling data by the quantitative computer-based TrueAllele® interpretation system would result in an efficient recovery of the constituent genotypes due to newfound abilities to compute a maximum LR from sub-samples with skewed weight ratios, and to jointly interpret all possible pairings of sub-samples using a joint likelihood function.As a proof of concept, 10 separate cell samplings of size 20 recovered by LCM from each of two 1:1 buccal cell mixtures were DNA-STR profiled using a specifically developed LCN methodology, with the data analyzed by the TrueAllele® Casework system. In accordance with the binomial sampling hypothesis, the sub-samples exhibited weight ratios that were well dispersed from the 50% center value (50 ± 35% at the 95% level). The maximum log(LR) information for a genotype inferred from a single 20 cell sample was 18.5 ban, with an average log(LR) information of 11.7 ban. Co-inferring genotypes using a joint likelihood function with two sub-samples essentially recovered the full genotype information. We demonstrate that a similar gain in genotype information can be obtained with standard (28-cycle) PCR conditions using the same joint interpretation methods. Finally, we discuss the implications of this work for routine forensic practice. 相似文献

All fifty states and the federal government have passed laws to combat human trafficking, but we know little about their effectiveness. Using data from investigative case records and court files for 140 human trafficking cases in 12 U.S. counties and qualitative interviews with law enforcement, prosecutors, and victim service providers, we examined the characteristics of and challenges to investigation and prosecution of human trafficking cases under new state and federal laws. We found that few human trafficking cases are identified by local law enforcement, most cases forwarded to state prosecution are sex trafficking cases involving U.S. citizens, and state prosecutors overwhelmingly charge human trafficking offenders with other, lesser crimes. The legal, institutional, and attitudinal challenges that constrain prosecution of human trafficking are similar across study sites despite varying types of state antitrafficking legislation. Study results suggest prosecution of human trafficking cases is challenging. If new laws are to be effective, then local law enforcement and prosecutors should work collaboratively and adopt proactive human trafficking investigative strategies to identify both labor and sex trafficking cases. There is social benefit to holding traffickers accountable, but more emphasis should be placed on policies that identify and serve victims. 相似文献

Vaccination involves the encounter of nonhuman biological matter and human bodies, recalibrating our susceptibility to illness and death. This boundary-crossing act has been caught in conflicting webs of moral significance, including the normalizing frameworks of public health governance and its corresponding forms of resistance. Such tensions and dynamics were a feature of smallpox vaccination - the first modern, systematic state-driven project to build population immunity. Focusing on smallpox vaccination in the British-ruled Straits Settlements (Singapore, Penang, and Malacca) between 1868 and 1926, we examine the recurrent features of contentions over vaccination from the tentative beginnings of the 1868 Vaccination Ordinance to the systematic extension of vaccination in the 20th century. Engaging science and technology studies of nonhuman agency and social theories on security, we argue that such contentions demonstrate the limits of a power formation we call governing through contagion (GTC). GTC centralizes law and other technologies to normalize public health measures that combat contagious diseases, while dysconnecting populations by its strategies of control. Our history of smallpox vaccination reveals: (i) GTC relies on the interconnectedness of human and nonhuman actors in protecting populations against viral threats; law is essential but does not necessarily drive vaccination or other strategies of control and (ii) resistance to GTC, in which law plays an integral role, reinforces inequalities and differentiated treatment, what we term endemic inter/dysconnectedness. 相似文献
