This article considers the design of federal earthquake policy as an illustration of the difficulties of addressing “public risks” when public indifference, despite general awareness of the risks, is the norm. The present federal earthquake policy attempts to overcome this indifference through strategies aimed at building local governmental commitment to risk reduction and improving nonfederal capacity to implement risk reduction programs. Because of the fundamental difficulties in influencing actions among less capable and willing jurisdictions, federal efforts have resulted in disjunctive impacts among seismic prone regions. Some “leading” communities have become more prepared, while other “lagging” communities in the same region fall further behind. The preferred approach for overcoming these gaps entails a mix of federally backed earthquake insurance coupled with development of local regulatory standards. More generally, strategies for addressing public risks entail modification of the policy tools for addressing such “private risks” as crime and job-related accidents. The changes involve mechanisms that shift from individual responsibility to shared responsibility for addressing the risks. 相似文献

We reviewed the case records of all fatalities due to gunshot wounds in children and adolescents under 19 years of age in New York City from 1996 to 2000. The epidemiological profile, circumstances, toxicology results, location, and injuries were examined. There were 263 deaths: 242 homicides, 17 suicides, and 4 accidents. Among the homicides, 96% involved Black or Hispanic and 68% involved 17 and 18-year-old decedents. There were 11 times as many male as female homicides. The detection of ethanol and/or illicit drugs was 56% in the homicide and 53% in the suicide groups. Suicide notes were found in 18% of suicides, and an additional 35% verbally expressed a plan to commit suicide. Most suicides (77%) were in the home and half of the homicides occurred on the street. 相似文献

Various forces have led to new thinking about approaches tointergovernmental regulation, emphasizing a shift from the heavyhand of coercive mandates to more cooperative approaches. Thisresearch examines the implementation of cooperative policiesaddressing aspects of environmental management in New SouthWales, Australia, and in New Zealand. Analyses are undertakenof the cooperative policy designs, government agencies' implementationefforts and styles, and local government officials' perceptionsof intergovernmental cooperation. Bringing about intergovernmentalcooperation is not automatic, nor does it appear to be easy.An empirical modeling shows that high levels of agency commitmentand capacity are required in order to foster facilitative implementationstyles. The design of policy mandates is important in signalingcooperative desires and structuring implementation to fosterappropriate agency implementation styles. 相似文献

Others have investigated the role that DNA profiling could play as a method for identifying the perpetrator of manual strangulation. These studies have demonstrated that it is possible to collect offender DNA from the skin surface of a victim following physical contact. It is not known whether nonself biological material is normally present on the skin surface due to adventitious transfer occurring during innocent everyday interactions. To test the hypothesis that detectable amounts of nonself DNA are normally present on the skin surface of healthy adult individuals due to the adventitious transfer of DNA occurring during normal day-to-day social interactions, we designed an experiment in three phases. Phase 1 was used to deduce which DNA collection, extraction, and amplification methods were suited to investigating this question. During phase 2, the neck surface of 24 healthy adult volunteers was swabbed. DNA was extracted using the QIAamp DNA mini kit and amplified using the SGM Plus PCR amplification kit, using 28 PCR cycles. The work carried out during phase 3 involved a simulated assault to investigate primary and secondary transfer of DNA during physical contact. It was found that 23% of neck areas swabbed during phase 2 of this investigation showed nondonor alleles in the resulting DNA profile, with 5% of areas showing six or more nondonor alleles. The results of phase 3 showed that primary, secondary, and zero transfer of victim and/or offender DNA could be observed after physical contact and that alleles from an unknown source could still be detected in this more controlled experiment. The data presented in this paper demonstrate that DNA profiles generated after swabbing the skin surface of healthy adults can include components of an unknown source, present due to adventitious transfer. These components, if present in large quantities, have the potential to interfere with DNA profile interpretation of swabs taken for the investigation of physical assault by DNA profiling. 相似文献

‘Illegals’ are extensively trained individuals dispatched abroad under false identities with no observable links to their operating country. Technology has made possible a new kind of ‘virtual illegal,’ one that extends beyond the operating country’s borders without putting a human at risk. When this is done in a targeted manner by a sophisticated attacker it is called an Advanced Persistent Threat (APT). This article draws from historical illegals cases to identify parallels in the preparation, insertion, and control of malware by APTs. Ultimately, the methods for countering the two parallel phenomena can also be similar, despite their physical differences. 相似文献

This article examines the impact of low-level police enforcement on two British drug markets, and the adaptations to enforcement made by sellers and buyers. The two markets took very different forms. One was tightly controlled by a small number of middle-level dealers, and highly structured. The structure and control worked effectively to minimise risks posed by law enforcement. The other market was very loosely structured, with little control exercised on retail sellers by middle-level dealers. This lack of organisation posed different sets of problems for law enforcement. The article examines the potential for developing the role of police sources (informants) in disrupting drug markets of both sorts. It also argues the need for provision in parallel of local treatment facilities for drug users. 相似文献
