In this article we break new ground by investigating cooperative agreements in urban development services, which include urban development, housing and sanitation for small local governments in Brazil (i.e., those with fewer than 20,000 residents in 2013–15). We find that public expenditure on urban development can be explained by both horizontal (intermunicipal cooperation) and vertical (public–public partnerships) cooperation. Regarding the impact of public sector cooperation on public expenditure, our results show that housing and sanitation services are less costly under intermunicipal cooperation. By contrast, urban development services are less costly when local authorities do not cooperate with other public entities. For public–public partnerships (with the state or federal government) cooperation leads to an increase in public funding, which implies that cooperative agreements might not lead to lower public expenditure. The findings in this article provide useful empirical insights into the administrative reorganization of Brazilian local government.  相似文献

The findings of this study make a timely contribution to the development of public services. Based on the institutional analysis and development (IAD) framework, this study analyzes under which institutional settings state-owned enterprises (SOEs) can be social and financial options for public service provision in Brazil. Applying a multi-case research design, this study’s findings show that SOEs can be a suitable option for Brazilian social and financial development when: markets are weak or noncompetitive; if few decisional players act; if political interference is minimized regarding operational decisions; and if corporate control is effective to avoid mismanagement and corruption. Brazilian SOEs are effective economic and social tools, but they need to peroxide value improve their corporate control (in the case of Petrobras) and strategic centralization decisions (in the case of Eletrobrás) .  相似文献

This article discusses Ronald Dworkin’s first objection against what he calls external moral skepticism, the view that denies truth-value to moral judgments. According to that objection, an external skeptic denies that substantive moral judgments can be true. But, at the same time, the objection goes, what follows from the skeptical view is that all actions are morally permissible, which is in itself a substantive moral judgment. We call this ‘the self-defeating argument.’ We argue that the objection’s success depends on how we interpret the idea of moral permission, an issue Dworkin does not clearly resolve. Against his objection, we advance two different arguments. First, once we learn what role the idea of moral permission plays in morality, we can see that any plausible view of some agent’s moral permission must acknowledge its complex character, and that the existence of a moral permission must have some impact on the balance of moral reasons for other agents. On this understanding, it is false that it follows solely from external skepticism that everything is permissible. Second, we argue that even if permissions have a simple character, not a complex one, they are plausible only when framed within a moral constellation of rights and obligations. So understood, it is, again, false that it follows from external skepticism that everything is permissible.  相似文献

Push factors associated with necessity entrepreneurship are largely neglected in the academic entrepreneurship literature. We link research on technology transfer to the literature on opportunity and necessity entrepreneurship, showing that the rate of academic spin-off creation is positively associated with the skilled unemployment rate. This longitudinal study of 559 spin-offs launched between 1999 and 2013, which controlled for several university- and context-level factors, showed that a higher level of unemployment reduced the probability of academic spin-off creation up to a threshold, beyond which the effect was reversed. By contrast, the relative skilled unemployment level was related positively to the probability of academic spin-off, particularly high-tech spin-off, creation. The relationship between the level of skilled unemployment and the creation of high-tech spin-offs was moderated positively by university research orientation and regional research and human capital intensity.  相似文献

Most law students in the UK embark upon their degrees hoping to become solicitors or barristers and yet the current legal landscape is in a state of flux. Students are incurring significant costs to try and break into an increasingly competitive market and are concerned that they do not have the skills and experience that many employers expect. With this in mind, Plymouth Law School tracked the aspirations and destinations of its LLB students and graduates over a number of years, exploring factors that encouraged or inhibited them along the path to their careers. This article evaluates the data from our students and considers its relevance to the employability issues highlighted by the LETR.  相似文献

Dental age assessments are widely used to estimate age of immature skeletal remains. Most methods have relied on fractional stages of tooth emergence and formation, particularly of the permanent dentition, for predicting the age of infants and very young children. In this study, the accuracy of regression equations of developing deciduous tooth length for age estimation (Liversidge et al.) is tested on a sample of 30 Portuguese subadult skeletons of known age at death. Overall the method shows high accuracy and the average difference between estimated and chronological age is between 0.20 and -0.14 years when using single teeth, and 0.06 years, when using all available teeth. However, there is a tendency for the deciduous molars to provide overestimates of chronological age. Results show that age estimates can be obtained within +/-0.10 years with a 95% confidence interval when several teeth are used. Overall between-tooth agreement in age estimates decreases with increasing age but there is less variability of estimates with more teeth contributing to overall mean age. One seemingly limitation of this method may be the fact that it was developed by combining the maxillary and mandibular teeth. The other is related to the accuracy with which radiographic tooth length can be used as a valid surrogate for actual tooth length. Nevertheless, the advantages of this metric method surpass the limitations of chronologies based on stages of dental development.  相似文献
