目的 :观察清宫汤协助药物流产 (药流 )的作用 ,并探讨其机制。方法 :将 36 0例药流者随机分成单纯药流组 (不用其他任何中西药 )、催产素组 (待孕囊排出后用催产素 )、清宫汤组 (在药流当天服清宫汤 ) ,临床观察 3组出血情况 ,并进行动物实验。结果 :流产效果 :清宫汤组不全流产率明显低于单纯药流组 (P <0 .0 5 ) ;阴道出血疗效 :清宫汤组显效率及总有效率明显高于另两组 (P<0 .0 5 ) ;阴道出血量 :清宫汤组出血量少者明显多于单纯药流组 (P <0 .0 5 )。动物实验证实 ,清宫汤能增强动情小鼠体外子宫平滑肌的收缩功能 ,增加收缩频率和活动力 ,并能减轻小鼠耳郭肿胀及抑制冰醋酸所致的腹腔血管通透性增高 ,与对照组比较 ,差异有显著性 (P <0 .0 5或P <0 .0 1)。结论 :清宫汤可配合药流提高流产效果 ,减少不全流产 ,缩短出血时间 ,减少出血量 ,安全有效     

A Public Choice Analysis of Endangered Species Listings

Sizable economic consequences may resultfrom listing under the Endangered SpeciesAct (ESA). Potentially adversely affectedparties will attempt to use the politicalprocess to protect their interests. Thequestion is, “are listing determinationssubject to political manipulation?” Inthis paper, we explore empirically thepossibility that implementation of the ESAis determined, in part, by politicalconsiderations. Specifically, weinvestigate whether states with strongcongressional representation are able touse their political muscle to reduce thenumber of listings in their states, ascompared to states with weak congressionalrepresentation. Controlling for otherfactors, we find that states with greaterrepresentation on the U.S. Fish andWildlife Service’s budgetary oversightsubcommittee in the U.S. House ofRepresentatives have significantly fewerESA listings than states with weakerrepresentation on that subcommittee.     

Renaturalisierung sozialer Ungleichheiten? Zu Wolfgang Kerstings vergeblicher Hoffnung, auf dem Weg von John Rawls über Robert Nozick zu einer liberalen Sozialstaatsphilosophie zu gelangen

In 2000, Wolfgang Kersting gave a much acknowledged outline concerning a liberal welfare state-philosophy within the debate on libertarianism and egalitarianism. Kersting, who used to sympathize with John Rawls’ theory of justice, now bases his approach on a ‘naturalism of merits’, which he polemically distinguishes from all egalitarian forms of political liberalism. This article deals with Kersting’s way from John Rawls’ ‘Theory of Justice’ (1971) via Robert Nozick’s ‘Anarchy, State, and Utopia’ (1974) to his present conception of a minimal welfare state; furthermore, the article points out that Kersting’s conception is appropriate neither to the complexity of modern societies nor to the basic normative standards of the classical political liberalism.     

Under Two Flags: Symbolic Voting in the State of Mississippi

Participants in a specialelection held in the State of Mississippion April 17, 2001, voted overwhelminglyagainst changing the design of the state'sflag, which incorporates a symbol of theConfederacy. The determinants of voting onthe flag are analyzed and turnout rates inApril 2001 are compared with those forrecent gubernatorial and presidentialelections. We find that the flag votedivided Mississippians sharply along linesof race, class and political ideology. Akey empirical implication is that voterpositions in issue space tend to be morepolarized when political choices haveexpressive as opposed to instrumentalconsequences.     

Tinpots,Totalitarians (and Democrats): An Empirical Investigation of the Effects of Economic Growth on Civil Liberties and Political Rights

Ronald Wintrobe (1990, 1998) has recently provided atheoretical foundation for estimating equations that attemptto explain the dependence of civil liberties and politicalrights in non-democratic regimes on the history of economicgrowth. This theory suggests that data from different kinds ofnon-democratic countries should not be pooled without allowingcoefficients to vary with regime type. It also placesinteresting restrictions on the signs of the coefficients ofeconomic growth in equations explaining freedom in the typesof regimes Wintrobe identifies. In this paper, we employ theserestrictions to test Wintrobe's theory. Some additionalhypotheses about the difference between democratic andnon-democratic regimes and about the role of education, notconsidered by Wintrobe, are also investigated.The results indicate clearly that the relationship between thedegree of freedom – as measured by the sum of the Gastilindexes of civil liberties and political rights – andeconomic growth varies significantly across all types ofregimes. Totalitarians (that attempt to maximize power) areclearly different than tinpots (that just attempt to maintainpower) in this respect, and non-democratic regimes differ fromdemocracies. Other aspects of the theory are partiallyconfirmed. In particular, in totalitarian regimes, positivegrowth reduces freedom, and negative growth increases it insome specifications. The theory predicts the opposite patternfor tinpots, and we do find that negative growth reducesfreedom in tinpot regimes. However, positive growth in tinpotsalso appears to reduce freedom in some cases, which is not inaccord with the theory. Secondary schooling has a positive effect on freedom, as inprevious empirical work, a result that is shown here to holdeven when each type of regime is considered separately. Butthe effect of primary schooling is different: in tinpot andtotalitarian regimes, but not in democracies, primaryschooling is associated with reduced freedom.     

Conceptualising State Capacity: Comparing Kazakhstan and Kyrgyzstan

Strengthening the state is central to the post-communist reform agenda. Here, state capacity combines organisational, material and social resources and is conceptualised along four dimensions: ideational, political, technical and implementational. This conceptualisation is applied to a comparative, survey-based analysis in 2002 of 125 medium-ranking officials in two post- communist Central Asian countries, Kazakhstan and Kyrgyzstan. The findings reveal that although Kazakhstan's controlled economic reform programme and natural resources have placed it in a stronger position to develop its state capacity, important ideational, political and implementational problems pose long-term obstacles for reform. In turn, Kyrgyzstan's early liberalisation in the absence of economic and social resources may be serving to undermine its state capacity.     

Citizen Participation in Decision Making: Is It Worth the Effort?

It is widely argued that increased community participation in government decision making produces many important benefits. Dissent is rare: It is difficult to envision anything but positive outcomes from citizens joining the policy process, collaborating with others and reaching consensus to bring about positive social and environmental change. This article, motivated by contextual problems encountered in a participatory watershed management initiative, reviews the citizen-participation literature and analyzes key considerations in determining whether community participation is an effective policy-making tool. We list conditions under which community participation may be costly and ineffective and when it can thrive and produce the greatest gains in effective citizen governance. From the detritus of an unsuccessful citizen-participation effort, we arrive at a more informed approach to guide policy makers in choosing a decision-making process that is appropriate for a community's particular needs.     

Whether one votes and how one votes

The aim of this paper is to determine if whether one votes effects the vote that is cast. Using an economic model of voting and observed voting results on nuclear power referenda, the answer is a resounding yes. Overcoming registration, turnout, and “roll off” hurdles dramatically increases the odds of voting against nuclear power. Indeed, participation swamps both economic and preference variables in the explanation of nuclear power voting outcomes. The lesson is that there is a structure to participation at the polls that should not be ignored by those interested in analyzing voting outcomes.     

Pre-electoral coalitions in comparative perspective: A test of existing hypotheses

Despite the vast coalition literature, pre-electoral coalitions have never been at the center of any systematic, cross-national research. Given their prevalence and potential impact on government composition and policies, this represents a serious omission in our knowledge of coalitions. I begin to remedy this situation by testing two hypotheses found in the literature on party coalitions. The first is that pre-electoral coalitions are more likely to form in disproportional systems if there are a sufficiently large number of parties. The second is that pre-electoral coalitions are more likely to form if voters face high uncertainty about the identity of future governments. These hypotheses are tested using a new dataset comprising legislative elections in 22 advanced industrialized countries between 1946 and 1998. The results of the statistical analysis support the first hypothesis, but not the second.
