This paper empirically examines the impact of corruption on the structure of government spending by sector. Using the three-stage
least squares method on 64 countries between 1996 and 2001, we show that public corruption distorts the structure of public
spending by reducing the portion of social expenditure (education, health and social protection) and increasing the part dedicated
to public services and order, fuel and energy, culture, and defense. However, civil and political rights seem to be a stronger
determinant of expense on defense than corruption. Our results are robust to instrumentation by the latitude of the country. 相似文献

The manufacturer's requirement of increasing productivity results in the need to design work stations that are increasingly more effective and specialized. However, this procedure can bring about an overloading of the worker, a lack of motivation, and, consequently, a reduction in productivity.Ergonomics adapts the work station to the worker with the object of improving his welfare and satisfaction at his post. One aspect that this science concerns itself with is the evaluation of physical demands connected to productive tasks. Mechanical movements are also studied in order to perform tasks efficiently.We here propose a new method of physical demand analysis that determines the risk factor for muscular skeletal lesion. This method uses, as a base, the system of predetermined times, MTM-UAS. It includes a computer system that allows us to easily analyse the operations at a work station and generates charts similar to those of UAS, but, instead of times, it measures the quantity of mechanical work necessary for each movement.The information that the method provides can be used by different divisions within companies in making decisions about improvements at work stations. 相似文献

Open Source Software projects base their operation on a collaborative structure for knowledge exchange in the form of provision
or reception of information, expertise and feedback on the creation of source code. Here, we address the direction of these
knowledge flows among projects throughout social networks and their impact on project success. We identify the roles of membership
or contribution that individuals play within projects. We found that connections through contributors who bring their knowledge
to the project, improve project success, and that connection through members, who transfer their knowledge towards other projects,
enhance project success. Finally, we found that ties through shared membership and contributions hamper project success. The
analysis of knowledge flows and their impact on project success imply a translation of returns from investment in social capital,
where investment takes the shape of knowledge flows and the returns mean the projects’ diffusion over the network.

Previous studies suggest that entrepreneurs play a key role in the success of their ventures. But relatively little is currently known about how they produce such effects. The present research provides data suggesting that two modes of entrepeneurs’ self‐regulation—locomotion and assessment—enhance a firm's success through their effects on the components of alertness. This mediational model was tested and supported with data from 120 entrepreneurs. Locomotion was positively related to the scanning and search component, while assessment was positively related to the association and evaluation components. These findings are discussed in terms of the role of founders’ self‐regulation in the performance of their companies. 相似文献

This article aims to evaluate the service quality experienced at academic conferences held at the Universidad Técnica Particular de Loja in Ecuador. Our approach is based on fuzzy logic and ideal solutions to calculate a global attendee satisfaction index for specific market segments: Gender, nationality, and age. Current literature on the service quality experienced by conference attendees is still scarce. Our results show that the analyzed segments experience varying levels of satisfaction, and that the more influential attributes to each of them are also different. Our results can be applied to improve the competitiveness of Loja and that of Universidad Técnica Particular de Loja. 相似文献

Aims: Although several therapeutic options are available for chronic immune thrombocytopenic purpura (cITP), little is known about the treatment of cITP in Brazil.Materials and methods: A multi-center, retrospective chart review, observational study was designed to describe the treatment patterns, clinical burden, resources use, and associated costs for adult patients diagnosed with cITP and treated in public and private institutions in Brazil. Patient charts were screened in reverse chronological order based on their last visit post January 1, 2012. (All costs were calculated using 1.00 USD?=?3.9571 BRL, from February 2016.)Results: Of 340 patient charts screened, 50 patients were eligible for inclusion in the study. Single-drug therapy (prednisone, dexamethasone, or dapsone) was the most commonly used treatment, followed by combination therapies (azathioprine?+?prednisone, azathioprine?+?prednisone?+?danazol, and prednisone?+?dapsone). Splenectomy was performed in 22% of patients after at least first-line treatment. Platelet count and number of bleeding episodes at diagnosis were 31,561.1/mm3 (SD?=?±26,396.1) and 40 episodes, respectively; in first-line, 92,631.1/mm3 (SD?=?±79,955.3) and 19 episodes, respectively; in second-line, 96,950.0/mm3 (SD?=?±76,476.4) and 17 episodes, respectively. Private system patients had a higher median cost compared to public system patients (USD 17.49/month, range?=?0–2,020.77 vs USD 9.51/month, range?=?0–192.64, respectively).Limitations: This study does not allow conclusions for causal explanations due to the cohort study design, and treatment patterns represent only the practices of physicians who have agreed to participate in the study.Conclusions: The data indicate that available therapeutic strategies for second- and third-line therapies appear to be limited. 相似文献

Abstract Vendors of meals and snacks, granted the realities of the present changing economic and social lifestyles, will continue to feed large numbers of people despite the insanitary conditions under which most of them operate. This study sought to find out the degree of patronage of food sold by vendors, items purchased, reasons for patronizing, views and opinions on the services patronized. Two-hundred and forty-five students resident in five halls at the University of Ghana completed a self-administered questionnaire each. Eighty-six per cent purchased cooked meals and snacks regularly from vendors. Over two-thirds consumed their meals at the selling sites. However, the services and facilities offered by vendors were judged as inadequate and poor. Nineteen per cent reported having suffered diarrhoea, stomach aches, indigestion and other gastrointestinal problems as a result of eating vendored foods. Three outstanding reasons emerged for the high patronage of vendored foods. They are food always being available (69%); food being cheaper (62%); and more variety to choose from (42%). These findings portray the great influence of money and time on consumer choice of food in our present harsh economic environment. Patrons indicated several unhealthy practices by vendors that pose health threats to patrons. These observations together with several recommendations made regarding the safe handling of food, water and the environment indicate consumers' awareness of the need for safe delivery of the food they consume. There is the urgent need therefore to organize and train vendors, pass a food law, supervise operations of vendors and also educate consumers to choose only safe food and water and insist on a clean food environment. 相似文献

Mapping the benefits and costs associated with process innovation: The case of RFID adoption 总被引:2,自引:0,他引:2
The successful implementation of any innovation requires an understanding of its benefits and costs. This study examines the changes in the magnitude of costs and benefits associated with technology process innovation adoption as the innovation diffuses across different industries. Using RFID as an exemplar technology, the study shows that the magnitude of benefits and costs associated with technological process innovation adoption within different industries varies as technology diffuses beyond early adopters to the early majority. During the early stages of technology evolution, the development cost, the cost of capital, ethical costs and simple direct implementation costs (in the form of the cost of tags) predominate. As a dominant design emerges the profile of costs changes with the emphasis on initiation costs, more holistic direct implementation costs and indirect implementation costs. A similar change in the emphasis of benefits is observed, with a shift from direct to indirect benefits being noticeable as the technology moves from early adopters to early majority adopters. Our findings help to explain the difficulties in consistently measuring innovation outcomes observed in the innovation implementation literature, and emphasize the need to take into consideration the stage of technology development as a significant factor that influences the realised outcomes from innovation implementation. 相似文献

Bargaining one-dimensional social choices 总被引:1,自引:0,他引:1
We analyze bargaining over the one-dimension characteristic of a public good among n impatient players when decisions require q favorable votes, q?2. Stationary subgame perfect equilibrium strategies are characterized for all games with deterministic protocol. We provide a monotonicity condition (satisfied by all single-peak, strictly quasi-concave and concave utilities) that assures uniqueness for every q whenever player's utilities are symmetric around the peak. Without symmetry, the monotonicity condition assures uniqueness for qualified majorities, q>n/2, provided that agents are sufficiently patient and utilities satisfy an additional regularity condition. Asymptotic uniqueness is assured for qualified majorities by imposing only the monotonicity condition. 相似文献
