Kenya's agriculture ministries are reforming their accounting systems and the reform includes computerization. This article examines the impact of computers on accounts and the lessons that can be drawn from Kenya about building computerized accounting systems.
Four propositions emerge about the impact of computers on the accounting systems. First and surprisingly, the initial impact of computers is indirect. Their primary impact is to strengthen the manual accounts which the ministries continue to rely upon. Second, computers promote effectiveness reforms by changing procedures, rather than efficiency reforms by accelerating the throughput of data with existing procedures. Third, computers do not initially promote document processing but do improve data processing. Fourth, computers do promote rudimentary analysis.
One conclusion from the Kenya case is that modular implementation of computerized accounting is helpful. Implementing modules rather than an integrated system means that accounting reforms can begin without waiting for lengthy procedural reforms. Modular implementation also facilitates agency involvement in the design of the system.  相似文献

Decentralization is argued to create incentives for local and regional politicians to be more responsive and accountable to their constituents, but few studies have directly tested this claim. We use survey data from Colombia to examine individual‐level evaluations of the degree to which decentralization prompts citizens to view department government as more accountable. We estimate the effect of administrative, fiscal, and political decentralization, controlling for participation, political knowledge, confidence in government, education, and income on perceptions of accountability. Our results indicate that administrative and fiscal decentralization improve perceptions of accountability, while political decentralization does not.  相似文献

Although many studies of clientelism focus exclusively on vote buying, political machines often employ diverse portfolios of strategies. We provide a theoretical framework and formal model to explain how and why machines mix four clientelist strategies during elections: vote buying, turnout buying, abstention buying, and double persuasion. Machines tailor their portfolios to the political preferences and voting costs of the electorate. They also adapt their mix to at least five contextual factors: compulsory voting, ballot secrecy, political salience, machine support, and political polarization. Our analysis yields numerous insights, such as why the introduction of compulsory voting may increase vote buying, and why enhanced ballot secrecy may increase turnout buying and abstention buying. Evidence from various countries is consistent with our predictions and suggests the need for empirical studies to pay closer attention to the ways in which machines combine clientelist strategies.  相似文献

This article explains how informal institutions have prevented the emergence of autonomous judges in Paraguay between 1954 and 2011. The central argument is that co‐optation, clientelism, and judicial corruption considered as informal institutions, rooted during the dictatorship, have impeded the appearance of an independent judicial branch in the democratic regime. To test this hypothesis, the article relies on historical narratives, surveys, and semistructured interviews. The conclusions suggest that in countries that have experienced the consolidation of informal institutions oriented toward maintaining the ties of subordination of judges to politicians, constitutional reforms and fragmentation of political power are necessary but not sufficient conditions for improving judicial independence.  相似文献

This article sets out to provide a broad overview of the ways in which kidnapping and abduction can be contextualised and understood. First, it will review kidnapping and abduction by examining the varying definitions used by practitioners, academics, governmental organisations, non‐governmental organisations and private sector interests. Second, a discussion of related offences, including piracy, hostage‐taking, hijacking, tiger kidnap, express kidnap and state‐sponsored rendition, and others is undertaken. Third, there will be an examination and review of the various typologies that have been suggested by researchers in the field, culminating in the suggestion of a revised and comprehensive typology.  相似文献

Since the 1980s, the so-called “nomadic” populations in the regions of Northern Mali and Niger have embarked on an extensive process of settlement. Today they mostly live in villages or “settlement sites”. But, at the same time, individuals and small groups among these same populations have considerably enlarged their area of mobility and accelerated the rate and the value of the trade in which they engage. These two phenomena could, at first sight, appear contradictory. But the observation of empirical situations shows, rather, compatibilities, similarities even, between these two concomitant phenomena. Building on innovative debates conducted in geography and sociology, this article puts forward the hypothesis that the building of villages, as well as integration into military bases and barracks, proceeds from (social) rationales of mobility, just as much as transhumance, journeys, migration. Much more than a simple displacement in space, the notion of mobility could describe an “art of doing”, a way of being to others and to the world.  相似文献

In many criminal and civil cases in China, the most commonly questioned documents are those written with gel pen ink. An important task for forensic document examiners is to identify whether two or more ink entries in one or more documents were written with the same ink type. The identification of the age of gel ink entries made poses an important and difficult problem for forensic document examiners. In this paper, the volatile components of gel ink were determined and the gel ink was classified by gas chromatography with a flame ionization detector. Calibration curves were created to express the relationship between the content of volatile gel ink components and the age of gel ink entries stored under natural and UV‐induced aging conditions. The correspondence between the natural and UV‐induced aging conditions was also established. The experimental results showed that GC was useful in the analysis of black gel ink and applicable for determining the relative age of gel ink entries under certain conditions.  相似文献
