This study emphasizes the need to include purchasing, or procurement, as a topic in the graduate-level public administration curriculum. It notes the absence of purchasing research in mainstream public administration journals and in leading public financial management textbooks. The study also reports the results of a survey mailed to the purchasing directors of the 46 largest U.S. counties outside Florida. The survey was designed to familiarize academians and practitioners with various administrative, legal, structural, and procedural dimensions of county procurement policies. Areas of greatest deficiency are those dealing with protest and appeals procedures and contract monitoring, and to a lesser extent procedures for declaring an emergency, entering into intergovernmental purchasing agreements, and contracting with minority businesses. The most comprehensively-covered elements are those delineating award authority, small purchase authority, methods of soliciting bids, definitions of emergencies and professional services, and procedures for contracting professional services. 相似文献

Three vote-share equations are estimated and analyzed in this article, one for presidential elections, one for on-term House elections, and one for midterm House elections. The sample period is 1916–2006. Considering the three equations together allows one to test whether the same economic variables affect each and to examine various serial correlation and coattail possibilities. The main conclusions are (1) there is strong evidence that the economy affects all three vote shares and in remarkably similar ways; (2) there is no evidence of any presidential coattail effects on the on-term House elections; (3) there is positive serial correlation in the House vote, which likely reflects a positive incumbency effect for elected representatives; and (4) the presidential vote share has a negative effect on the next midterm House vote share, which is likely explained by a balance argument. 相似文献

ABSTRACTIn the UK and some US states, video-recorded investigative interviews of child victims/witnesses can be presented in court as the child’s evidence-in-chief. However, there is scarce advice or research on the effect that presenting different sections of the interviews may have on juror perceptions of the child’s testimony. Two aspects of testimony presentation are examined here: first, whether to show the rapport-building phase of the interview, and second, the presentation of multiple interviews (i.e. more than one interview with the same child). Participants (n?=?103) informed they were watching two interviews of the same child separated by a week had more positive perceptions of the child’s testimony than those informed they were watching just one extended interview with a ten-minute break. Also, those watching the rapport-building phase had less positive perceptions of the child’s testimony than those who did not watch this phase. Participants’ perceptions of the interviewer and their case progression decisions were mainly not related to the above presentational differences. Thus, (i) mock-jurors were not inherently biased against multiple interviews and (ii) decisions regarding whether or not to show the rapport-building phase in court may have significant effects on jurors’ perceptions of the child and their testimony. 相似文献

Purpose
To examine the effect of victimization on self-control.Method
Five waves of data from the GREAT survey are analyzed; the effect of prior victimization on subsequent self-control is estimated using the dynamic panel generalized-method of moments.Results
Victimization reduces subsequent self-control in the near term.Conclusions
The findings point to another source of low self-control, help to explain why prior victimization is linked to subsequent victimization, and provide support for general strain theory - which predicts that strains such as victimization will reduce self-control. 相似文献107.

When underivatized methamphetamine hydrochloride (MA.HCl) in methanol is subjected to the instant gas chromatographic-mass spectrometric (GC-MS) profiling with old inlet liners at temperatures above 200 degrees C, appreciable amounts of N,N-dimethylamphetamine (DMA) and amphetamine (AP) are produced. The presence of these two artifacts is attributed to the N-demethylation and N-methylation reactions of MA as well as methyl group exchange with methanol. These artifacts are only produced in old injection port liners and at elevated temperatures. The formation of artifacts is proportional to concentration of MA.HCl. It is suggested that special cautions and measures be undertaken to prevent artifacts. 相似文献

Homeland Security Preparedness: The Rebirth of Regionalism 总被引:1,自引:0,他引:1
The homeland security mission has placed many new demands onthe U.S. system of federalism. The successful implementationof homeland security policy requires cooperation among all levelsof governmentfederal, state, and local. Regionalism offersa powerful tool for encouraging greater intergovernmental cooperationand improved homeland security preparedness. We assess the impactof regionalism on intergovernmental cooperation and the implementationof the homeland security mission in Florida, an early proponentof the regional approach. From a regional perspective, we evaluatehow intergovernmental complexity, the quality and quantity ofintergovernmental networks, and security vulnerabilities contributeto perceived improvements in intergovernmental cooperation andhomeland security preparedness. The results of a 2004 mail surveyof city and county officials suggest that regional organizationalstructures are most effective in promoting intergovernmentalcooperation and preparedness where the intergovernmental landscapeis the most complex and where security vulnerabilities are themost intense. 相似文献
