Mongolia's transition to a market economy has entailed rapid and extensive privatisation accompanied by, inter alia, stabilisation, liberalisation and de‐regulation. The primary objective of this strategy was to cement the new political and economic order. Little weight was given to the problems created by the privatisation programme and only limited consideration given to questions of regulation in the economic, social and environmental spheres. However, the failure of the economy to translate economic growth into poverty reduction and the acceleration of the privatisation programme, which includes the progressive transfer of land, and proposals to privatise health, educational and cultural assets, have made regulation a more pressing issue. New, powerful social classes and interest groups have emerged, which have contributed to regulatory failure and capture and have undermined public policy. We identify a range of issues relating to privatisation and regulation and discuss the degree to which they are being addressed by the post‐1990 political class. Although there exist a number of regulatory agencies, there is a lack of political commitment, and only piecemeal implementation and enforcement. The scarcity of experienced and technically competent staff capable of establishing and operating effective regulatory agencies and ensuring compliance is also a major problem.

Web 2.0 innovations may enhance informed patient decision-making, but also raise ethical concerns about inaccurate or misleading information, damage to the doctor-patient relationship, privacy and confidentiality, and health disparities. To increase the benefits and decrease the risks of these innovations, we recommend steps to help patients assess the quality of health information on the Internet; promote constructive doctor-patient communication about new information technologies; and set standards for privacy and data security in patient-controlled health records and for point-of-service advertising.  相似文献

Abstract. In the standard Downsian model, voters are assumed to choose parties based on the extent of ideological proximity between the voter's own position and that of the party. Yet it is also well known that there are rationalization and projection effects such that voters tend to misestimate the policy platforms of candidates or parties to which they are sympathetic by overstating the correspondence between those positions and the voter's own preferences (see, e.g., Markus & Converse 1979; Granberg & Brent 1980; Granberg & Holmberg 1988; Merrill & Grofman 1999). Here we follow insights in the psychological literature on persuasion (Sherif & Hovland 1961; Parducci & Marshall 1962) by distinguishing between assimilation and contrast effects. Assimilation refers to shortening the perceived ideological distance between oneself and parties one favors; contrast refers to exaggerating the distance to parties for which one does not intend to vote. Using survey data on voter self–placements and party placements on ideological scales for the seven major Norwegian parties, five major French parties, and two major American parties we show that both assimilation and contrast effects are present in each country to a considerable degree.We also investigate the possible effects of randomness in party placement and scale interpretation – effects that can easily be confounded with assimilation but not so easily with contrast.  相似文献

Kindergarten teacher ratings of physical aggression, hyperactivity,inattention, anxiety, and prosocial behavior were used to predictself-reported delinquency, peer-rated social withdrawal, and schoolplacement in preadolescence (ages 10 to 12 years) in a large longitudinalsample of boys from low socio-economic neighborhoods. Two analyticstrategies were used: person-oriented and variable-oriented approaches. Inthe person approach, eight clusters, based on the kindergarten behaviors,were used to predict delinquency, social withdrawal, and schoolplacement. In the variable approach, the kindergarten behaviors were used asdimensions in logistic regressions. Family adversity was used as the firstpredictor in both approaches; it significantly predicted all the outcomes inpreadolescence. The results obtained using the two approaches were partly inaccordance. In both sets of results, kindergarten teacher-ratedexternalizing behavior problems were most related to later self-reporteddelinquency, and internalizing problems to peer-rated socialwithdrawal. However, the person approach showed that all patterns ofkindergarten behavior problems increased the risk for placement out of anage-appropriate regular classroom, while only inattention and lack ofprosocial behavior were the significant dimensional predictors of thisnegative outcome according to the variable approach. Also, the personapproach showed that the Multiproblem kindergarten boys had the highestpercentage of comorbidity of preadolescent problems. The ROC curvesindicated that prediction of delinquency, social withdrawal, and schoolplacement were equally accurate using the cluster and variableapproaches. Advantages and limits of both approaches are discussed withreference to their usefulness for clinicians.  相似文献

Niemi (1969), in an important but neglected paper, found that when orderings were drawn from a simulation based on the impartial culture, the greater the proportion of voter orderings that were single-peaked (a condition he called partial single-peakedness), the more likely was there to be a transitive group ordering. Niemi also found that the likelihood of transitivity increased with n, group size — approaching one as n grew large. Niemi's simulation was restricted to the case of three alternatives. Also, he provided no theoretical explanation for the results of his simulation. Here we provide a theoretical explanation for Niemi's results in terms of a model based on the idea of net preferences, and we extend his results for the general case of any finite number of alternatives, m, for electorates that are large relative to the number of alternatives being considered. In addition to providing a rationale for Niemi's (1969) simulation results, the ideas of net preferences and opposite preference we make use of have a wide range of potential applications.  相似文献
