Six ninhydrin analogues containing oxygen, sulfur, and selenium substituents at the C-5 position, 5-(4-nitrophenyl)ninhydrin, and benzo[f]furoninhydrin were evaluated as fingerprint development reagents. The analogues all showed good fingerprint color development but were not superior to ninhydrin in this respect. The benzo[f]furoninhydrin complex was strongly luminescent at room temperature following zinc complexation, while the remaining analogues required cooling to -196 degrees C to produce optimum luminescence. The benzo[f]furo, nitrophenyl, and methyl selenide analogues showed the best potential as fingerprint reagents with the benzo[f]furo analogue comparing favorably with DFO. 相似文献

In 2006, the Public Choice Society chose a new president using approval voting. There were five candidates, and the election was extremely close. We indicate the sources of support of the different candidates, based in part on spectral analysis, by voters who cast between one and five votes. Using preference information that was also gathered, we show that two candidates different from the approval voting winner, including the apparent Condorcet winner, might have won under different voting systems. Because most voters did not indicate their complete preference rankings, however, these differences are hardly robust, especially since the outcome was essentially a dead heat. 相似文献

This study examines the role of car ownership in facilitating employment among recipients under the current welfare‐to‐work law. Because of a potential problem with simultaneity, the analysis uses predicted car ownership constructed from two instrumental variables, insurance premiums and population density for car ownership. The data come from a 1999–2000 survey of TANF recipients in the Los Angeles metropolitan area. The empirical results show a significant independent contribution of car ownership on employment. The presence of an predicted ownership is associated with a 9 percentage point increase in the odds of being employed. Moreover, the results indicate that lowering insurance premiums by $100 can increase the odds of employment by 4 percentage points. © 2002 by the Association for Public Policy Analysis and Management. 相似文献

How do German ministries manage the preparation of national negotiation positions for EU intergovernmental conference? After a survey of the debate on organizational deficits of the interministerial coordination in Germany, we are consulting decision- and organization-theoretic approaches in IR. Drawing on organizational economics we concretise and supplement these older frameworks. We conceive the management of a governmental organization as a specific aggregation of heterogeneous preferences and information. Applying social network analysis we take into account formal as well as informal aspects of coordination channels. The objective of this article is to make visible the complex structures and processes that constitute foreign policy making, and to provide a preliminary assessment of its efficiency. 相似文献

Researchers in political science are devoting increasing attention to the ontological commitments of their theories – that is, to what those theories presuppose about the nature of the political world. This article focuses on a recent contribution to this 'ontological turn' in political science ( Sibeon, 1999 ). Tensions are identified in Sibeon's account of the causal interplay between agency and social structure. It is argued that these tensions can be resolved by reflecting explicitly on ontological issues, in particular the causal efficacy of social structure, using a particular approach to the philosophy of the social sciences known as critical realism. The value of such reflection for the explanatory power of political analysis is highlighted. 相似文献

The 'real war' and 'propaganda war' fought over Northern Ireland for thirty years polarised party and public opinion. The key dilemma faced by politicians during the recent peace process has been how to wind down the 'war' and win sufficient party and public support for an accommodation between unionists and nationalists which falls so far short of previous expectations. Scripts telling contrasting stories have been prepared to convince rival republican and unionist audiences to support the peace process. In addition, the pro-Agreement parties have attempted to shift opinion towards accommodation through a range of political skills and choreography. Key competing parties and governments have sometimes co-operated back stage while front stage they have on occasion 'play acted' conflict between each other. The political skills, or lying and manipulation, by which the peace process has been driven forward have been uncovered creating public distrust in the political process. Realists see such political deception as an inevitable part of politics and permissible on the grounds that the ends justify the means. Absolutists attack the 'spin, lying and manipulation' of the peace process as an assault on democracy. A third democratic realist position argues that sometimes moral leadership requires doing wrong to do right but the gap between 'truth' and 'spin' should be narrowed. A more open and honest politics would not only be more accountable and democratic but also effective in advancing the peace process. 相似文献

Within Europe, the Danish electorate is the one that has most often expressed its opinion about the European Union in elections and in national referendums. Votes and attitudes are analysed for the five elections to the European Parliament between 1979 and 1999 and in the six referendums – from the first on membership of the EC in 1972 to the September 2000 referendum on acceptance of the euro, the European single currency. The article gives an overview of the development of Danish public opinion in relation to the European Union from 1960 to 2000, the turnouts at referendums, and the elections and results for the European Parliament. It is shown that since Denmark joined the EU, public opinion has fluctuated greatly, although the balance among Danish European Parliament members has remained stable. The reasons for the frequent use of referendums in Denmark and a thematic outline of the six referendums are put forward. The article concludes with a comprehensive analysis of public attitudes towards the referendum on the euro in 2000. It is shown that regional electoral patterns have vanished, but underlying attitudes are manifested in the public. 相似文献
