The alleles present at the HLA DQ alpha locus may be typed by either allele specific oligonucleotide (ASO) probing or by restriction mapping, referred to here as amplification restriction fragment polymorphism (ARFP) analysis. ASO typing relies upon hybridization principles, whereas ARFP typing relies upon restriction site analysis. Dot-blot ASO typings which are of doubtful interpretation may be directly checked by ARFP analysis. Aliquots of the PCR products amplified using the commercial Amplitype HLA DQ alpha system are digested with suitable restriction endonucleases. Electrophoresis, blotting and detection of biotin-labelled restriction fragments provides a sensitive and robust typing method suited to forensic analysis. 相似文献

Family violence and Asian drinkers 总被引:1,自引:0,他引:1
This is a study of 70 consecutive referrals to the Department of Psychological Medicine, National University Hospital, for treatment of drinking problems. There were 31 Chinese and 39 Indian drinkers, with 63 males and 7 females. Family violence with physical abuse occurred in 21 cases (30%). One of three wives of drinkers had been physically abused, but no children were victims. Drinkers with family violence were generally younger and more severely dependent on alcohol than the non-violent drinkers. There was no relationship between family violence and the ethnicity or marital status of the drinkers. 相似文献

For most of the 19th century, the labor movements of England and America seemed to be developing along similar lines. Then, in the decades around the turn of the century, both movements were embroiled in a common battle over the political soul of trade unionism. In England, the champions of broad, class-based social and industrial reforms prevailed. In the United States, they lost, and the winners were the voluntarists, who held that labor should steer clear of politics as much as possible. This article suggests that the key reasons for the divergence lie not in the sociology of the working class or labor movement, so much as in the character of the state and polity and the lessons trade unionists drew from experiences in those arenas. The difference between judicial supremacy in the United States and parliamentary supremacy in England combined with other differences in the two nations'forms of government to produce sharply contrasting lessons about the value of state-based reforms. 相似文献

An epidemiological study was conducted to characterize adult, domestic homicides committed with firearms and to determine the role of alcohol intoxication in the likelihood of becoming a homicide victim. Data on 129 homicides in Ohio occurring between 1982 and 1985 were collected from police departments of major cities, the Ohio Department of Rehabilitation and Corrections, and county medical examiners. Forty-eight offenders were interviewed. Temporal and geographical patterns are discussed, as well as offender-victim relationships and the characteristics of the firearms used. High levels of blood alcohol in the victims suggest that alcohol is a risk factor for becoming a homicide victim, although data on alcohol consumption patterns in the population are necessary to advance this association. 相似文献

Public administrators rely on written communications to send information to citizens and stakeholders, and they are among the heaviest users of the postal service. Behavioral science research has identified several techniques that public administrators can use to increase compliance with written requests and, in turn, increase effectiveness. Currently, however, many written communications from government bodies are not written in a manner that utilizes these techniques. It remains an ongoing challenge for public administrators to identify, understand, and use these techniques in the written communications sent by their organizations. This article presents a framework capturing seven prominent techniques in a simple mnemonic—INSPIRE—that is already being used by several government bodies in Australia. It also provides practical examples of how to use each technique and demonstrates that using these techniques could result in large aggregate improvements in effectiveness and socially desirable outcomes of public administrators' written communications. 相似文献

Central governments face compliance problems when they rely on local governments to implement policy. In authoritarian political systems, these challenges are pronounced because local governments do not face citizens at the polls. In a national‐scale, randomized field experiment in China, we test whether a public, non‐governmental rating of municipal governments' compliance with central mandates to disclose information about the management of pollution increased compliance. We find significant and positive treatment effects on compliance after only one year that persist with reinforcement into a second post‐treatment year. The public rating appears to decrease the costs of monitoring compliance for the central government without increasing public and media attention to pollution, highlighting when this mode of governance is likely to emerge. These results reveal important roles that nonstate actors can play in enhancing the accountability of local governments in authoritarian political systems. 相似文献

Can deliberative mini-publics contribute to deepening the democratic dimensions of electoral democracies? The question is framed in this article using a problem-based approach to democratic theory–to count as democratic, political systems must accomplish three basic functions related to inclusion, communication and deliberation, and decision making. This approach is elaborated with an analysis of a real-world case: a deliberative mini-public with a citizens’ assembly design, focused on urban planning convened in Vancouver, Canada. This example was chosen because the context was one in which the city's legacy institutions of representative democracy had significant democratic deficits in all three areas, and the mini-public was a direct response to these deficits. It was found that Vancouver's deliberative mini-public helped policy makers, activists and affected residents move a stalemated planning process forward, and did do so in ways that improved the democratic performance of the political system. Depending on when and how they are sequenced into democratic processes, deliberative mini-publics can supplement existing legacy institutions and practices to deepen their democratic performance. 相似文献

While policymakers often make bold claims as to the positive impact of intellectual property (IP) rights on both developed and developing country economies, the empirical literature is more ambiguous. IP rights have both incentive and inhibitory effects that are difficult to isolate in the abstract and are dependent on economic context. To unravel these contradictory effects, this article introduces an index that evaluates the strength of IP protection in 124 developing countries for the years 1995 to 2011. We illustrate the value of this index to economics study and show evidence that is consistent with IP leading to increased growth. Our results are further consistent with two causal pathways highlighted in the literature: that IP leads to greater levels of technology transfer and increased domestic inventive activity. Yet other aspects of our study fit uneasily with this simple story. For example, we find evidence suggesting that increased levels of growth lead to greater levels of IP protection, contradictory evidence in the literature linking IP with growth, a lack of evidence that increased levels of IP protection lead to actual use of the IP system, and problems with what IP indexes measure. Because of this, we suggest another – and so far undertheorized – explanation of the links between IP and growth: that IP may have few direct effects on growth and that any causality is a result of belief rather than actual deployment of IP. 相似文献
