After the break up of the Soviet Union the conflict over energy resources in the Caspian area has flared up again. The United States has entered the stage, but the only remaining superpower finds it hard to forward its security policy interests and interests in the economic sphere in the area. The creation of a US‐dominated hegemony in the area would be beneficial for the United States, but the policy of containment of Iran and Russia, and US policy towards Azerbaijan seriously limits this possibility. Thus it is not possible to secure American influence in the Caspian area. In the long term this leaves the area open to Russia and Iran, or new actors such as China and the EU, unless the United States is willing to soften its policy vis‐à‐vis Iran and/or Azerbaijan in order to create the needed hegemony, and in this way achieve economic and political influence in the former Soviet republics. 相似文献

Using data from the 2002 Wisconsin Advertising Project and a Democratic direct mailing firm, we ask if candidates publicly court African American and Hispanic voters through the inclusion of these groups in their campaign advertisements or through appeals to their substantive policy interests. We find evidence that Democratic and Republican candidates make symbolic and substantive appeals only when these appeals are very unlikely to be viewed by White voters. These findings lend credence to studies that conclude that candidates are hesitant to publicly court minority voters due to concerns that such activities may harm their existing electoral coalitions, particularly their standing with White voters. 相似文献

Locating exactly where trace explosive residue samples should be sought during sample collection at bomb scenes is not specified in the published literature or guidelines; in this area, it is generally acknowledged that forensic practices are based on tradition rather than evidence. This study investigated patterns in the spatial distribution of postblast 1,3,5‐trinitro‐1,3,5‐triazocyclohexane residue from a series of unconfined detonations, over a range of sampling sites, and at two different detonation heights. The amount of residue recovered from the sites decreased as a function of distance from the center of the explosion. [Correction added after online publication 27 December 2012: In the preceding sentence, “increased” was corrected to “decreased” to agree with the conclusion of the article.] As the height of the detonations increased, more residues were found from all sampling sites. The findings of this empirical study have a number of important practical implications including determining where residue samples are best sought at crime scenes. 相似文献

Much debate has taken place regarding the merits of aggressive policing strategies such as “stop, question, and frisk.” Labeling theory suggests that police contact may actually increase delinquency because youth who are stopped or arrested are excluded from conventional opportunities, adopt a deviant identity, and spend time with delinquent peers. But, few studies have examined the mechanisms through which police contact potentially enhances offending. The current study uses four waves of longitudinal data collected from middle‐school students (N = 2,127) in seven cities to examine the deviance amplification process. Outcomes are compared for youth with no police contact, those who were stopped by police, and those who were arrested. We use propensity score matching to control for preexisting differences among the three groups. Our findings indicate that compared with those with no contact, youth who are stopped or arrested report higher levels of future delinquency and that social bonds, deviant identity formation, and delinquent peers partially mediate the relationship between police contact and later offending. These findings suggest that programs targeted at reducing the negative consequences of police contact (i.e., poor academic achievement, deviant identity formation, and delinquent peer associations) might reduce the occurrence of secondary deviance. 相似文献

During forensic anthropological investigation, biological profile is determined by age, sex, ancestry, and stature. However, several individuals may share the same profile. Observation of discrete traits can yield useful information and contribute to identification. This research establishes the frequency of discrete traits of the sternum and ribs in a modern population in southern France, using 500 computer tomography (CT) scans of individuals aged 15–60 years. Only discrete traits with a frequency lower than 10% according to the literature were considered, a total of eight traits. All scans examined were three‐dimensional (3D) volume renderings from DICOM images. In our population, the frequency of all the discrete traits was lower than 5%. None were associated with sex or age, with the exception of a single trait, the end of the xiphoid process. Our findings can usefully be applied for identification purposes in forensic anthropology and medicine. 相似文献

A suicide pact is the decision of two or more people to die together. This event is rare. The majority of suicide pacts victims are married, socially isolated, with a serious physical illness in one or both partners. We performed a retrospective study of all cases of suicide pacts leading to death between January 1, 2003 and December 31, 2010 referred to the Forensic Medicine Department of Tours (France). Six cases were recorded as suicide pacts. Firearms were the preferred means of death. Five suicide notes were discovered. For some cases, it was difficult to establish whether death was the result of a suicide pact or of a homicide–suicide without the consent of the victim. An objective element, such as a suicide note and motive, is required to prove that a suicide pact is involved. The prevalence of mental disorders is hard to assess. In France, psychological autopsies are not performed in such cases, as the investigation is usually very sparse after the death of both individuals. 相似文献

The authors report an unusual case of suicide of an anesthesiologist, in which the suicide manner and means depend upon the victim's occupation. This is the first case report published in Italy of a death involving propofol and other drugs. The anesthesiologist was found dead with an empty drip still inserted in the hand and another one near his body. Forensic and toxicological findings suggested that the cause of death was a respiratory depression due to a self‐administration of a rapidly infused lethal drug mixture. Analytical drug quantification was performed by gas chromatography‐mass spectrometry. Blood analysis revealed: zolpidem (0.86 μg/mL), propofol (0.30 μg/mL), midazolam (0.08 μg/mL), thiopental (0.03 μg/mL), and amitriptyline (0.07 μg/mL). Adipose tissue and hair analysis suggested a previous and repeated use of these drugs verifying the fact that in Italy recreational abuse of anesthetic and sedative agents in health care practitioners is becoming an increasing problem. 相似文献

Mitochondrial DNA (mtDNA) is a valuable tool in the fields of forensic, population, and medical genetics. However, recording and comparing mtDNA control region or entire genome sequences would be difficult if researchers are not familiar with mtDNA nomenclature conventions. Therefore, mtDNAprofiler, a Web application, was designed for the analysis and comparison of mtDNA sequences in a string format or as a list of mtDNA single‐nucleotide polymorphisms (mtSNPs). mtDNAprofiler which comprises four mtDNA sequence‐analysis tools (mtDNA nomenclature, mtDNA assembly, mtSNP conversion, and mtSNP concordance‐check) supports not only the accurate analysis of mtDNA sequences via an automated nomenclature function, but also consistent management of mtSNP data via direct comparison and validity‐check functions. Since mtDNAprofiler consists of four tools that are associated with key steps of mtDNA sequence analysis, mtDNAprofiler will be helpful for researchers working with mtDNA. mtDNAprofiler is freely available at http://mtprofiler.yonsei.ac.kr . 相似文献

Since the Korean criminal DNA database was launched in 2010, we have focused on establishing an automated DNA database profiling system that analyzes short tandem repeat loci in a high‐throughput and cost‐effective manner. We established a DNA database profiling system without DNA purification using a direct PCR buffer system. The quality of direct PCR procedures was compared with that of conventional PCR system under their respective optimized conditions. The results revealed not only perfect concordance but also an excellent PCR success rate, good electropherogram quality, and an optimal intra/inter‐loci peak height ratio. In particular, the proportion of DNA extraction required due to direct PCR failure could be minimized to <3%. In conclusion, the newly developed direct PCR system can be adopted for automated DNA database profiling systems to replace or supplement conventional PCR system in a time‐ and cost‐saving manner. 相似文献

Performance of likelihood ratio (LR) methods for evidence evaluation has been represented in the past using, for example, Tippett plots. We propose empirical cross‐entropy (ECE) plots as a metric of accuracy based on the statistical theory of proper scoring rules, interpretable as information given by the evidence according to information theory, which quantify calibration of LR values. We present results with a case example using a glass database from real casework, comparing performance with both Tippett and ECE plots. We conclude that ECE plots allow clearer comparisons of LR methods than previous metrics, allowing a theoretical criterion to determine whether a given method should be used for evidence evaluation or not, which is an improvement over Tippett plots. A set of recommendations for the use of the proposed methodology by practitioners is also given. 相似文献
