In a continuing effort to reform and reinvent the way public organizations do business, the outsourcing of services has become a popular tool, particularly as resource constraints limit options available to governments. All too often, the decision is made, for reasons of ideology or resource constraints, to outsource services without giving careful consideration to the impact of privatization on the core missions of an agency, or whether privatization, in fact, offers real cost savings. Purchasing tools designed for traditional commodity purchases are often grossly unsuited for making decisions on specialized technical services.
This article suggests a process for the evaluation of an option to outsource laboratory services. It suggests that, prior to contracting or privatizing services, the concerned agency should evaluate:
the impact on the agency's core mission
the availability, stability, and reliability of private sector service providers
the relative costs of internal and external (public or private sector) service providers
the potential impact on regulatory enforcement
the ability to monitor the performance of external providers
potential conflicts of interest
Based on this model, the ongoing internal evaluation of services offers public agencies management tools to obtain the best value for the taxpayer dollar, not only in terms of the raw cost per test, but also in managing the quality of the services.  相似文献

The veto players theory can be used to analyze all political systems regardless of regime (presidential or parliamentary), party system (one-, two-, or multiparty), and type of parliament (unicameral or multicameral). This paper develops the veto players theory to account for a series of important political phenomena: the difference between majoritarian and supermajoritarian institutions; the importance of absenteeism, or of political marginalization; the importance of agenda control and referendums; the reasons for government stability (parliamentary systems) and regime stability (presidential systems); the reasons for independence of bureaucracies, and judicial independence. All these phenomena are analyzed in a coherent way, on the basis of the same framework. Empirical evidence from existing literature corroborating the theory is provided.  相似文献

This paper tests the validity of the Buchanan-Wagner hypothesis for Greece, that increases in public spending are the result of the tolerance of large deficits over the period 1961–1994. To test this hypothesis, three unit-root pretests, the Dickey-Fuller, Phillips-Perron and Kwiatkowski et al. and maximum likelihood estimation techniques of cointegrating vectors and a vector error-correction model are employed. A long-run relationship is found to exist among government spending, deficit, income,wages and adult population and the importance of short-run deviations are presented. The empirical evidence suggests that Buchanan and Wagner hypothesis, seems to find support for Greece in the long-run and the short-run. Further, productivity in the public sector is lower than in the private sector and the growth of income is not an important determinant of the increase in the relative size of public spending.  相似文献

While sociological concepts have often been implicitly used in International Relations (IR), recent years have seen a more explicit engagement between IR and Sociology. As with any such interdisciplinary assignation, there are both possibilities and challenges contained within this move: possibilities in terms of reducing IR's intellectual autism and opening the discipline towards potentially fertile terrain that was never, actually, that distant; challenges in that interdisciplinary raiding parties can often serve as pseudonyms for cannibalism, shallowness and dilettantism. This forum reviews the sociological turn in IR and interrogates it from a novel vantage point—how sociologists themselves approach IR concepts, debates and issues. Three sociological approaches—classical social theory, historical sociology and Foucauldian analysis—are critically deployed to illuminate IR concerns. In this way, the forum offers the possibility of (re)establishing exchanges between the two disciplines premised on a firmer grasp of social theory itself. The result is a potentially more fruitful sociological turn, one with significant benefits for IR as a whole.  相似文献

In order to assess the efficacy of vacuum metal deposition (VMD) as a technique to develop fingermarks on ballistic metallic surfaces, a preliminary study using six donors (three male & three female) was conducted. Using a sequential metal deposition process, two metal combinations were studied—gold/zinc and silver/zinc. Results indicate the potential of this technique, by developing identifiable fingermarks on brass metal disks aged from a few days up to more than a month old. As the development of fingermarks on fired (brass) cartridge cases is an area of interest, a further study was conducted where a total of 20 fingermarks were deposited on cases. After firing, second level fingermark characteristics were successfully observed on cartridge cases highlighting its potential as a fingermark enhancement method for ballistic brass materials. Further work is required to fully evaluate the VMD process and its reliability as a fingermark enhancing method on ballistic surfaces.  相似文献

Forensic practitioners are recommended to dark adapt their eyes prior to conducting evidential searches in the dark. The dark adaptation process remains poorly standardised across the discipline, with little quantified regarding the benefits of such preparative steps. Herein, we report the findings of a study that recruited 50 participants to assess the effectiveness of the Crime-lite Eye?, a darkness adaptation device developed to assist forensic practitioners both in the laboratory and in field. Participants were tasked with searching for the fluorescent signatures left by reaction of 1,8-diazafluoren-9-one (DFO) with amino acids, in a manner akin to the fluorogenic fingerprint treatment of porous evidence. Using an Epson Stylus Photo R265 inkjet printer, ink cartridges were filled with alanine solutions of various concentrations, allowing different motifs to be printed onto copy paper and subsequently developed using DFO. Participants searched for this ‘evidence’ both with and without dark adapted vision. On average, participants were able to locate and correctly recognise 16% more evidence once dark adapted using the Crime-lite Eye?.The increase in evidence located by participants once dark adapted suggests that crime scene officers should be dark adapting in order to visualise as much as possible. The time taken to dark adapt, 10?min on average during this study, is not excessively long, and should not significantly slow the investigation.  相似文献

Reports of identity theft in the U.S. have risen since the 2000s, which has resulted in financial losses into the billions. Along with this rise is the increased likelihood of familial identity theft. In this study, the differences between familial and non-familial identity theft were explored through the January–July 2012 Identity Theft Supplement collected with the National Crime Victimization Survey. Results showed that family member victims were likely to have experienced one type of identity theft more often than non-family victims were, personal information used for other fraudulent purposes, which included government benefits and driver’s licenses. Factors that allowed for a respondent’s personal information used for other fraudulent purposes included family membership, young persons in the household, and repeat victimization. Findings suggest that few factors can predict the likelihood to experience the misuse of personal information and that familial identity theft may be difficult to detect.  相似文献

An international project called PADS promoted participatory learning and action research with inland valley rainfed rice farmers in West Africa. All countries received the same training, similar funding, and the same leadership. Although the staff in Ghana were conscientious and gave much training to the farmer beneficiaries, the Mali staff explicitly encouraged farmers to experiment. Farmers in Mali responded to this favourable attitude by experimenting more than those in Ghana, and in qualitatively more interesting ways. Long-term engagement with grassroots organisations may be as conducive to changing public servants' attitudes as the actual participatory approach promoted on the ground.

L'attitude compte: travail avec des riziculteurs en Afrique de l'Ouest

Un projet international appelé PADS a favorisé l'apprentissage participatif et la recherche-action avec des riziculteurs pratiquant la culture pluviale dans les vallées de l'intérieur des terres en Afrique de l'Ouest. Tous les pays ont reçu la même formation, un financement similaire et le même leadership. Alors que les membres du personnel du Ghana étaient consciencieux et dispensaient une formation considérable aux agriculteurs bénéficiaires, le personnel du Mali encourageait expressément les riziculteurs à faire des expériences. Les riziculteurs du mali ont réagi à cette attitude favorable en faisant plus d'expériences que ceux du Ghana, et ce de manières plus intéressantes sur le plan qualitatif. L'engagement à long terme avec les organisations de la base populaire peut être tout aussi propice à la modification des attitudes des fonctionnaires que l'approche participative même promue sur le terrain.

As atitudes contam: Engajamento com produtores de arroz na África Ocidental

Um projeto internacional chamado PADS promoveu uma pesquisa sobre aprendizado e ação participativa com produtores de arroz irrigado com água da chuva no interior do vale na África Ocidental. Todos os países receberam o mesmo treinamento, financiamento semelhante e a mesma liderança. Embora os funcionários de Gana estivessem cientes e oferecessem bastante treinamento aos produtores beneficiários, os funcionários de Mali incentivaram explicitamente os produtores a experimentar. Os produtores de Mali responderam a esta atitude favorável experimentando mais do que aqueles de Gana e de maneiras mais interessantes em termos qualitativos. O engajamento de longo prazo com organizações de base pode contribuir para mudar as atitudes dos servidores públicos tanto quanto a abordagem participativa real promovida na base.

La actitud cuenta: el trato personal con campesinos arroceros de África Occidental

Un proyecto internacional llamado PADS promovió el aprendizaje participativo y la investigación-acción entre campesinos que cultivaban arroz de secano en los valles centrales de África Occidental. Todos los países participantes recibieron la misma capacitación, un financiamiento similar y las mismas orientaciones. Si bien el personal de Ghana era muy diligente y transmitió muchos conocimientos a los campesinos beneficiarios en capacitaciones, el personal de Malí se centró más explícitamente en animarlos para que experimentaran. Los campesinos de Malí respondieron a esta actitud estimuladora realizando más experimentos y de maneras cualitativamente más interesantes que los campesinos de Ghana. El compromiso de largo plazo con organizaciones de base puede ser tan importante para lograr un cambio en la actitud del servidor público como el método participativo que se promueve en la actualidad sobre el terreno.  相似文献
