It is estimated that on a single night in January 2009, there were 643,067 sheltered and unsheltered homeless people in America (The 2009 Annual Homeless Assessment Report to Congress 2010). The Obama administration recently published “Opening Doors,” the first federal plan to prevent and end homelessness. We argue that the strategy is based on a partial evidence base that raises questions about the potential of the strategy to meet its goals. In order to inform future iterations of the plan, data from 682 young adults (aged 18–27 years old; mean = 22.13 years old) who participated in the National Longitudinal Study of Adolescent Health were used to examine whether there is a typologys of young adults with a history of homelessness; one of the priority groups in the strategy. A priori selected variables previously associated with lifetime homelessness in non-random samples were mapped to survey items. Data were analyzed using cluster analysis. Comparisons were conducted with a randomly selected “never-homeless” sample from the same study. The cluster analysis revealed four subgroups. It appears that the Federal Plan currently prioritizes homelessness risk factors associated with two subgroups: the Young Offenders subgroup and the Abused Depressed subgroup. The needs of two other subgroups are not fully addressed: the Childhood Adversity subgroup and the Vulnerable African-American subgroup. The authors offer guidance on future directions for homelessness policy relevant to young adults. 相似文献

Territorial autonomy is one aspect of power-sharing in multi-ethnic societies. Nevertheless, the multi-ethnic countries of Central and Eastern Europe are still among the most centralised in the European Union. This article analyses the failure of any attempts to establish (symmetric) federalism or (asymmetric) autonomy, creating self-governed regions by the Hungarian minorities in Romania and Slovakia. The analysis focuses on the positions of the main parties of the ethnic majorities and the Hungarian minority parties in the two countries. In both cases, the parties representing the Hungarian minorities have favoured territorial autonomy along ethnic lines, but this demand has been rejected by the parties of the ethnic majority. Against the historical legacy of unstable borders, the parties of the ethnic majority argue that territorial autonomy or federalisation might be a first step for a revisionist agenda and separatism. Instead, supported by the European integration, the parties have been able to agree on decentralisation as a half-hearted compromise. 相似文献

A highly sensitive screening method based on high performance liquid chromatography atmospheric pressure ionization mass spectrometry (HPLC-API-MS) has been developed for the analysis of 21 nitroaromatic, nitramine and nitrate ester explosives, which include the explosives most commonly encountered in forensic science. Two atmospheric pressure ionization (API) methods, atmospheric pressure chemical ionization (APCI) and electrospray ionization (ESI), and various experimental conditions have been applied to allow for the detection of all 21 explosive compounds. The limit of detection (LOD) in the full-scan mode has been found to be 0.012-1.2 ng on column for the screening of most explosives investigated. For nitrobenzene, an LOD of 10 ng was found with the APCI method in the negative mode. Although the detection of nitrobenzene, 2-, 3-, and 4-nitrotoluene is hindered by the difficult ionization of these compounds, we have found that by forming an adduct with glycine, LOD values in the range of 3-16 ng on column can be achieved. Compared with previous screening methods with thermospray ionization, the API method has distinct advantages, including simplicity and stability of the method applied, an extended screening range and a low detection limit for the explosives studied. 相似文献

The FearID research project is aimed at the individualisation of earprints for the purpose of forensic research. The study presented here was carried out within the framework of this project. It intends to combine a review of what is known from literature on the classification and individualisation of earprints with results from a preliminary study of earprints. Possibilities for, and limitations to, the use of earprints in forensic investigation are addressed. Differences between eliminating a suspect, placing a suspect at a crime scene, and linking crimes by prints left at different scenes are considered. 相似文献

Extraction of human nuclear DNA from feces samples using the QIAamp DNA Stool Mini Kit 总被引:2,自引:0,他引:2
The use of a QIAamp DNA Stool Mini Kit (QIAGEN) for extracting human nuclear DNA from feces samples is reported. This method employs a stool lysis buffer and a unique matrix (InhibitEX tablet) to remove PCR inhibitory substances specific to feces samples. DNA extracted from various amounts of stool and from stool samples exposed to different environmental impacts was successfully amplified and typed using the Profiler Plus Amplification Kit and ABI PRISM 310 Genetic Analyser. 相似文献

Over the past decades the rate of completed suicide has remained quite stable, whereas that of suicide attempts seems to have increased (to the extent it has been studied in defined regions). These are puzzling observations, since depression is the major suicide precursor and and since antidepressants have been increasingly used over the years in the treatment of depression. These observations have not attracted sufficient attention, possibly because they do not accord with consensus opinions about depression treatment in psychiatry today. This paper discusses a number of possible explanations that not only deserve, but are definitely in need of systematic investigation. 相似文献
