正SINCE its establishment in 1947, the Winglaiyuen restaurant has become a well-known Hong Kong brand with an international reputation. Its development and expansion is largely due to one woman’s single-minded devotion.She is Wang Xiaoling."Running a successful restaurant is lucrative, but also hard work, because it demands whole-hearted devotion. Many brands build  相似文献

Human hairs are one of the most commonly encountered items of trace evidence. Currently, conventional methods for hair analysis include microscopic comparison and DNA analysis (nuclear and mitochondrial). Each approach has its own drawbacks. Hair proteins are stable and offer an alternative to DNA testing, as demonstrated with proteomics for distinguishing humans. However, proteomics is complicated and requires identifying peptides to remain intact following harsh sample preparation methods. Alternatively, the actual amino acid content of a hair sample may also offer important identifying information and actually requires proteins and peptides to be broken down completely rather than remaining intact. This study evaluated the discriminating power of using hair amino acid ratios to differentiate hair samples from 10 unrelated individuals with dark colored hair. Hair proteins were digested, derivatized, and analyzed using gas chromatography–mass spectrometry. Amino acid ratios were calculated for each individual and comparisons using ANOVA and post-hoc pairwise t-test with Bonferroni correction were made with amino acid ratios for individuals. Overall, out of the 45 possible pairwise comparisons between all hair samples, 38 (84%) were differentiable. Out of the 36 possible pairwise comparisons between brown haired individuals, 32 (89%) were considered differentiable using univariate statistics. Multivariate statistics were also attempted but, overall, univariate models were sufficient for exclusionary purposes. These results indicate that amino acid ratio analysis can potentially be used as an exclusionary method using hair if DNA analysis cannot be performed, or to corroborate conclusions made following microscopic analysis.  相似文献

Although federal arrangements adopt a multiplicity of forms across and within federations, this article suggests that some models of power division are better than others at enhancing clarity of responsibility and electoral accountability. This conclusion is the result of exploring responsibility attribution and economic voting in a state where decentralisation arrangements vary across regions: the Spanish State of Autonomies. Using electoral surveys and aggregated economic data for the 1982–2012 period, the empirical analysis shows that regional economic voting is most pronounced in regions where decentralisation design concentrated authority and resources at one level of government, whereas it is inexistent in regions where devolution followed a more intertwined model of power distribution. The implication of the empirical findings is that the specific design of intergovernmental arrangements is crucial to make electoral accountability work in federations.  相似文献

Relative to non-bias motivated crimes, hate crimes have much graver consequences for victims and their community. Despite the large increase in religious hate crimes over the past decade relative to all other hate crime, little is known about these types of crimes and the factors associated with both reporting to law enforcement and case outcomes. Utilizing the National Crime Victimization Survey and National Incident-Based Reporting System datasets, this study examines the relationship between victim, offender, and incident characteristics on reporting to law enforcement and case outcomes. Most religious hate crimes are not reported (41.3 %) in part due to perceptions of law enforcement’s perceived response. Of the violent incidents that are reported, the vast majority do not result in the arrest of an offender (22.2 %). Whereas only a small number of variables related to the seriousness of the offense are associated with both reporting and arrest, these exhibited large effect sizes.  相似文献

Specialized Family Care (SFC) provides planned, long term family foster care to youth who have been adjudicated as delinquent and who are at high risk of on-going delinquent behavior following their transition into the community from correctional confinement. The program is funded and operated through a collaborative arrangement among The Casey Family Program-Bismarck Division, the North Dakota Department of Human Services (DHS) and the North Dakota Division of Juvenile Services (DJS). Specially recruited, trained and supported foster families work closely with a dual case management system of services provided by SFC social workers and DJS case managers responsible for community-based aftercare. Individual case plans for youth involve a mix of intensive aftercare programming for delinquent behaviors, individually designed intervention strategies, intensive supervision, and intensive casework. This article discusses the program model, implementation challenges, costs and preliminary outcomes.  相似文献
