The importance of identification using the frontal sinus has been previously demonstrated in case reports. In this study, 39 cases of identification using frontal sinus comparison from the Ontario Chief Coroner's Office were reviewed and differences between antemortem and postmortem radiographs examined. All cases involved decedents older than twenty years. Three cases were rejected due to poor antemortem and postmortem film quality. One subject had no frontal sinus. Thirty-five cases provided conclusive postmortem to antemortem pattern matches. Sixteen cases also yielded metric (quantitative) matches. Duration between antemortem and postmortem radiographic examinations, age, gender, and cause of death did not affect the ability to obtain a match. This is the largest study undertaken on actual cases and demonstrates the validity of frontal sinus pattern matching for forensic identification. 相似文献

MPs have not previously been assigned a major role in electoral campaigning, being considered only one element of a political party's ‘marketing’ tools for winning votes. Evidence now suggests that the relationship between MPs and their constituents is changing. The concept of ‘constituency service’ implies that individual MPs can have a much greater influence on local voters and so possibly buck national trends. At the same time the concept of the ‘permanent campaign’ is transforming political campaigning whereby the political elite needs ever‐greater control of the tools used to provide messages to voters. The internet is a potential battleground between MPs who want greater control of their own local campaigning and the party elite who want to ensure a consistent, coherent and controlled message. The Internet is a new addition to the campaigning armoury, yet the focus so far has been on e‐government, e‐democracy and election campaigns. By concentrating on how and why MPs use their websites this paper considers whether MPs have fully understood and utilised this new medium. Key questions include whether their websites are ‘sticky’, interactive and a means of creating a targeted message. The findings of this detailed study of MPs' websites show that apart from a few pioneers, MPs have not progressed beyond using the Internet as ‘shovelware’ — the vast majority view their website as an electronic brochure and not a new form of two‐way communication.

This study examined the prevalence and correlates of sleep disturbance in adolescents. Two hundred seventy-seven 9th- and 10th-grade students completed a questionnaire on sleep quality, sleep habits, beliefs about sleep, and daytime mood and functioning. Based on their responses, subjects were classified as good sleepers (66%), occasional poor sleepers (23%), and chronic poor sleepers (11%). Occasional and chronic poor sleepers reported being significantly more depressed, without energy, tense, moody, and irritable and less rested and alert than good sleepers. They were also more likely to describe themselves negatively. However, poor sleepers were not consistently more tired than good sleepers. Rather, they tended to be least tired in the evening, the time when most good sleepers reported feeling tired. There were few differences in the sleep habits and beliefs about sleep of good and poor sleepers. All subjects reported shifts in bedtimes and waketimes from weekdays to weekends, with occasional and chronic poor sleepers showing a tendency toward greater shifts, a possible factor contributing to their sleep disturbance. Occasional and chronic poor sleepers also reported more observable behaviors and feelings of stress than good sleepers. The need for early intervention with particular attention to teaching adolescents about good sleep habits and the need for stable bedtimes and waketimes and the possibility of joint intervention on daytime stress and sleeping problems are discussed. 相似文献

The Gene Print PowerPlex 1.1/Amelogenin and FFFL Fluorescent STR Systems have been validated following the recommendations presented by the Technical Working Group on DNA Analysis Methods (TWGDAM). The PowerPlex 1.1/Amelogenin System supports simultaneous amplification of eight short tandem repeat loci and the Amelogenin gender identification marker. The loci D16S539, D7S820, D13S317, and D5S818 are labeled with fluorescein (FL) while the loci CSF1PO, TP0X, TH01, vWA and Amelogenin are labeled with carboxy-tetramethylrhodamine (TMR). The FFFL Multiplex System is composed of the loci F13A01, FESFPS, F13B, and LPL, each labeled with fluorescein. We have observed no overlap of alleles across loci labeled with an individual fluorescent dye. Samples of each system were amplified and labeled in a single reaction, separated by electrophoresis through a denaturing polyacrylamide gel, and amplified alleles detected using a Hitachi FMBIO Fluorescent Scanner. Alterations from the standard amplification protocols in cycle number and annealing temperature generally produced excellent results. In experiments testing sensitivity as little as 0.2 ng of DNA template could be detected. As expected, different body fluids from the same individuals generated identical DNA profile results. Template DNA derived from blood-strains deposited on a variety of matrix supports displayed robust amplification except for material derived from deposits on wood and Japanese orchid leaves. Mixtures of DNA templates could be interpreted with the minor component present in as little as ten percent of the total sample. Monoplex and multiplex amplifications produced identical amplified allele patterns, indicating that STR multiplex systems save template and increase efficiency in the amplification procedure without loss of quality. Analyses of genotype frequencies in African-American, Caucasian-American and Hispanic-American populations using all twelve loci were used to determine matching probabilities smaller than 1 in 1.14 x 10(8) and 1 in 2658 for the PowerPlex 1.1 and the FFFL Multiplex Systems, respectively. The matching probability achieved with the two systems combined is smaller than 1 in 3.03 x 10(11). The independence of alleles within loci was generally demonstrated by applying the exact test to demonstrate Hardy-Weinberg Equilibrium. All of the studies performed indicate that the PowerPlex 1.1/Amelogenin and FFFL Multiplex Systems are powerful, robust, and reliable investigative tools that can be used in the analysis of forensic samples. 相似文献

A number of empirical models have found protection to be greatest for industries employing poorly skilled, low paid workers. This has caused some economists, notably Robert Baldwin, to suggest that equity concern by politicians in an alternative to the interest group hypothesis. This paper reports the result of a test on New Zealand data that shows that this equity concern is absent for industries with few employees or firms. Equity concern variables were only important for industries with many employees and firms. This suggests that equity concern is selective and may be reconcilable with self-interest motivations.I am grateful to John Tressler, Richard Harris and an anonymous referee for their helpful comments. 相似文献
