The fundamental interactions between sebaceous constituents of fingermarks and three lipid specific fingermark enhancement reagents (solvent black 3, basic violet 3 and basic violet 2) are reported. The staining of fingermarks is investigated using optical microscopy, and the interaction of the reagents with individual constituents is explored using spot tests. It is demonstrated that solvent black 3, basic violet 3 and basic violet 2 all interact with different constituents of sebaceous sweat, and this may offer potential for using the reagents in sequence for fingermark enhancement. Further tests to explore the effect of dye concentration on reagent effectiveness indicate that dye concentration can be reduced by up to 25% without significant detriment to effectiveness. It is shown that there is little practical difference between solvent black 3 formulations with the solvents (ethanol and 1-methoxy-2-propanol) used in this study. The study also indicates that basic violet 2 may have some operational advantages over basic violet 3 and may be worthy of further investigation. 相似文献

In spatial voting games without a core, if candidates are constrained on one issue, they are implicitly constrained on other issues. Thus external constraints affect optimal positions for candidates. Using new solution concepts, we find the optimal position for a candidate given any linear constraint, given an opponent’s constraint, and determine conditions when constraints are sufficient to yield unbeatable positions. 相似文献

Utilizing 4-digit industry data by county,we compare the allocation of resourcesacross industries in state capital areaswith noncapital areas. We are able toidentify which industries are expanded andcontracted relative to noncapital areas. Our results provide the first directevidence and measurement of the forgoneproductive activity resulting fromresources being reallocated toward rentseeking and interest group activity. Ourdata also allow us to measure total rentseeking, and also to isolate the extent ofindirect and in-kind rent seeking, whichcan account for part of the Tullockparadox. 相似文献

Globalization,government spending and taxation in the OECD 总被引:7,自引:1,他引:6
Abstract. This article assesses the impact of globalization on welfare state effort in the OECD countries. Globalization is defined in terms of total trade, imports from low wage economies, foreign direct investment, and financial market integration. Welfare effort is analyzed in terms both of public spending (and separately on social service provision and income transfer programs) and taxation (effective rates of capital taxation and the ratio of capital to labor and consumption taxes). Year–to–year increases in total trade and international financial openness in the past three decades have been associated with less government spending. In contrast, integration into global markets has not been associated either with reductions in capital tax rates, or with shifts in the burden of taxation from capital to consumption and labor income. Moreover, countries with greater inflows and outflows of foreign direct investment tend to tax capital more heavily. 相似文献

Forensic examiners regularly testify in criminal cases, informing the jurors whether crime scene evidence likely came from a source. In this study, we examine the impact of providing jurors with testimony further qualified by error rates and likelihood ratios, for expert testimony concerning two forensic disciplines: commonly used fingerprint comparison evidence and a novel technique involving voice comparison. Our method involved surveying mock jurors in Amazon Mechanical Turk (N = 897 laypeople) using written testimony and judicial instructions. Participants were more skeptical of voice analysis and generated fewer “guilty” decisions than for fingerprint analysis (B = 2.00, OR = 7.06, p = <0.000). We found that error rate information most strongly decreased “guilty” votes relative to no qualifying information for participants who heard fingerprint evidence (but not those that heard voice analysis evidence; B = −1.16, OR = 0.32, p = 0.007). We also found that error rates and conclusion types led to a greater decrease on “guilty” votes for fingerprint evidence than voice evidence (B = 1.44, OR = 4.23, p = 0.021). We conclude that these results suggest jurors adjust the weight placed on forensic evidence depending on their prior views about its reliability. Future research should develop testimony and judicial instructions that can better inform jurors of the strengths and limitations of forensic evidence. 相似文献

The prime ministership is the preeminent political post in parliamentary democracies. Yet few studies examine PM party choice, perhaps under the assumption that the choice is a simple function of party size. In this article, we argue that key strategic actors and the context in which government negotiations take place can play a critical role in PM party choice. We test our hypotheses using a mixed logit with random coefficients on an original data set comprising PM selection opportunities in 28 European countries. Our methodological approach allows us to incorporate qualitative concerns about heterogeneity and causal complexity into our analysis. Contrary to conventional wisdom, we find that the largest party is often disadvantaged when it comes to PM party choice, that some presidents play an influential role in choosing the PM, and that the value of being the incumbent depends on one’s performance in office and how the previous government ended. 相似文献
