This study characterizes men who have engaged in habitual sexual conduct with children, or pedophiles. This examination is
designed as a content analysis using the academic and practitioner press to describe pedophilia characteristics among predators.
The sample of three convicted predators is not the focus of this investigation but used to primarily to help operationalize
the realities of pedophiles as seen in the literature. All three participants were offenders in a high profile event in the
region of the country where they individuals were apprehended, tried, and eventually convicted. The findings indicate that
the behavior of most pedophiles is a way of life prior to, during, and after incarceration. One implication arising from this
finding is that rehabilitation might be pointless for these offenders. Further research is suggested to determine classification
levels of pedophiles in order to best serve the communities these offenders are released into. 相似文献

While Carmines and Stimson's work on issue evolutions has prompted research showing the dynamics and effects of new party alignments on abortion, religion, gender and cultural issues, this research has all centred on the United States. This article examines issue evolution in Britain. Using evidence on the timing of changes in elite positions from Comparative Manifestos Group data, and survey data on public attitudes to the European Union with a longer historical sweep than heretofore, the article finds strong evidence that the European issue has followed an issue evolution path, though with distinct dynamics contingent on the pace of elite re‐positioning. Thus, this article extends the theory of issue evolution to a parliamentary political system and demonstrates the responsiveness of the public to elite cues, while also providing additional insights from a unique case in which elites have staked out distinct positions not once, but twice. 相似文献

The ability to properly collect, analyze and preserve biological stains is important to preserving the integrity of forensic evidence. Stabilization of intact biological evidence in cells and the DNA extracts from them is particularly important since testing is generally not performed immediately following collection. Furthermore, retesting of stored DNA samples may be needed in casework for replicate testing, confirmation of results, and to accommodate future testing with new technologies.A novel room temperature DNA storage medium, SampleMatrix™ (SM; Biomatrica, Inc., San Diego, CA), was evaluated for stabilizing and protecting samples. Human genomic DNA samples at varying amounts (0.0625-200 ng) were stored dry in SM for 1 day to 1 year under varying conditions that included a typical ambient laboratory environment and also through successive freeze-thaw cycles (3 cycles). In addition, spiking of 1-4× SM into samples prior to analysis was performed to determine any inhibitory effects of SM. Quantification of recovered DNA following storage was determined by quantitative PCR or by agarose gel electrophoresis, and evaluation of quantitative peak height results from multiplex short tandem repeat (STR) analyses were performed to assess the efficacy of SM for preserving DNA.Results indicate no substantial differences between the quality of samples stored frozen in liquid and those samples maintained dry at ambient temperatures protected in SM. For long-term storage and the storage of low concentration samples, SM provided a significant advantage over freezer storage through higher DNA recovery. No detectable inhibition of amplification was observed at the recommended SM concentration and complete profiles were obtained from genomic DNA samples even in the presence of higher than recommended concentrations of the SM storage medium. The ability to stabilize and protect DNA from degradation at ambient temperatures for extended time periods could have tremendous impact in simplifying and improving sample storage conditions and requirements. The current work focuses on forensics analysis; however this technology is applicable to all endeavors requiring storage of DNA. 相似文献
