Barack Obama's first year should appear disappointing only to persons blind to the constraints imposed by the Bush legacy, the still reeling world economy, an intimidating agenda of domestic problems, a polarised domestic politics, and at least temporarily intractable opponents of the President's undoubted ambitions to tame the Middle East and promote cooperation among the leading states without jettisoning a commitment to liberal values. By ordering an end to torture and moving to close Guantanamo, he has signalled the restoration of moral restraint on the exercise of American power and implicitly expressed belief in the efficacy of soft power assets. Additionally, he has attempted to create political space for change by pushing the conventional limits of American presidential discourse. A decent start, but the hard part lies ahead.  相似文献

Accurate age estimation has always been a problem for forensic scientists, and apposition of secondary dentine is often used as an indicator of age. Since 2004, in order to examine patterns of secondary dentine apposition, Cameriere et al. have been extensively studying the pulp/tooth area ratio of the canines by panoramic and peri-apical X-ray images. The main aim of this paper is to examine the relationship between age and age-related changes in the pulp/tooth area ratio in monoradicular teeth, with the exception of canines, by orthopantomography. A total of 606 orthopantomograms of Spanish white Caucasian patients (289 women and 317 men), aged between 18 and 75 years and coming from Bilbao and Granada (Spain), was analysed. Regression analysis of age of monoradicular teeth indicated that the lower premolars were the most closely correlated with age. An ANCOVA did not show significant differences between men and women. Multiple regression analysis, with age as dependent variable and pulp/tooth area ratio as predictor, yielded several formulae. R(2) ranged from 0.69 to 0.75 for a single lower premolar tooth and from 0.79 to 0.86 for multiple lower premolar teeth. Depending on the available number of premolar teeth, the mean of the absolute values of residual standard error, at 95% confidence interval, ranged between 4.34 and 6.02 years, showing that the pulp/tooth area ratio is a useful variable for assessing age with reasonable accuracy.  相似文献

This paper develops a framework for the analysis of gatekeeping in tax enforcement, whereby independent auditors are assigned the duty of attesting taxpayers’ returns. The equilibrium of the market for gatekeepers’ services is characterized, as well as taxpayers’ and auditors’ optimal behavior. The paper identifies the conditions under which the introduction of a mandatory attestation system is likely to be desirable.The results of the paper suggest that: (1) collusion may disrupt the gatekeeping system if the compounded liability of the auditor and the taxpayer is not sufficiently high; (2) a more extended delegation of the enforcement power to private auditors is generally desirable; (3) the cartelization of the gatekeepers’ market has definitely detrimental effects; and (4) when the probability that erroneous attestations are detected and sanctioned depends on the effort exerted by a public enforcer, multiple equilibria may arise, due to the substitutability of public and private monitoring.  相似文献

Childhood disruptive behaviors can be precursors to later deviance. To verify the efficacy of karate, a complex psychomotor activity that enhances self-regulation and executive skills, as an intervention for externalizing behaviors, 16 children, ranging in age from 8 to 10 years, and meeting diagnostic criteria for oppositional defiant disorder were studied. Eight were randomly assigned to a 10-month Wa Do Ryu karate program, whereas 8 children received no intervention. The children were assigned to a larger karate class, composed of typically developing youngsters. Three domains of temperament--intensity, adaptability, and mood regulation--were measured at the beginning and the end of the training period in all 16 participants. A significant improvement in temperament scale scores was measured in the karate group for all tested items compared to controls. Karate, when properly taught, can be a useful adjunct in multimodal programs aimed at externalizing behavior reduction.  相似文献

Results from a collaborative exercise with proficiency testing conducted by 20 Italian laboratories on the 15 loci included in the Identifiler kit were analyzed by allele sharing methods and by standard population genetics tests. The validated database, including about 1500 subjects, was merged with that of a previous exercise conducted on nine loci, and the resulting allele frequencies, subdivided by Italian region, were published on-line.  相似文献

Many studies have examined the characteristics of the frontal sinuses and their use for forensic purposes, particularly when an individual is edentulous. One of the most widespread classification systems is that proposed by Yoshino et al. The aim of this study was to improve the performance of Yoshino's method for identifying unknown skeletal remains by replacing the first two morphological items, frontal sinus size and bilateral asymmetry, by SOR1 = left frontal sinus area/left orbit area, and SOR2 = right frontal sinus area/right orbit area. According to the bivariate distribution of SOR = (SOR1, SOR2) and available data, we also estimated the probability of positive misclassification.  相似文献

Recently, the United Nations (UN) Security Council (SC) decidedto refer the situation in Darfur to the International CriminalCourt (ICC), following the suggestion of the UN Commission ofInquiry established by the Secretary-General pursuant to SCRes. 1564 (2004). The authors discuss four main problematicissues raised by the first SC referral of a situation to theICC. First, they emphasize that States Parties to the ICC andnon-States Parties have different obligations to cooperate withthe Court, irrespective of the adoption of a SC Resolution.Secondly, they discuss the question of immunity granted to nationalsof non-States Parties. Thirdly, the puzzling reference containedin the SC Resolution to exemption agreements is commented upon.Finally, the paper concludes with a criticism of the lack ofany measure providing for compensation to victims.  相似文献

The objective of this study was to investigate the links between maternal and paternal bonding, parental practices, orientation toward peers, and the prevalence of drug use and antisocial behavior during late adolescence. A model was tested using structural equation modeling in order to verify the robustness of the investigated links across 3 countries: Canada, France, and Italy. A self-report questionnaire was given to a sample of 908 adolescents, with an equivalent number of girls and boys, in Grade 11. The questionnaire assessed the following variables: parental bonding, parental supervision, parental tolerance, orientation toward peers, involvement in physically aggressive antisocial behavior, non-physically aggressive antisocial behavior, and drug use. The model was robust across the 3 countries, thus confirming a path that identified quality of emotional bonds between adolescents and their parents as a distal variable acting upon deviant behaviors through the following mediators: parental supervision, parental tolerance, frequency of conflicts, and orientation toward peers. Michel Claes is full professor at the Université de Montréal, Canada. He received his Ph.D. in Education from Université Catholique de Louvain, Belgium. His major research interest is in social development in adolescence, with a special focus on intercultural studies.  相似文献
