While the critically oriented writings of Immanuel Kant remain the key theoretical grounds from which universalists challenge reduction of international rights law and protection to the practical particularities of sovereign states, Kant’s theory can be read as also a crucial argument for a human rights regime ordered around sovereign states and citizens. Consequently, universalists may be tempted to push Kant’s thinking to greater critical examination of ‘the human’ and its properties. However, such a move to more theoretical rigour in critique only solidifies the subversive statism of Kant’s apparent universalism, as long as it remains embedded in his prior theory of critical philosophy that privileges a singular form of reason. Universalist theories of human rights can break with this contradiction only insofar as they also displace the right to philosophy from the subject and site of ‘civil’ man to a politics of theory where no such subject or site is guaranteed. 相似文献

Can the emergence of a new policy model be a catalyst for a paradigm shift in the overall interpretative framework of how economic policy is conducted within a society? This paper claims that models are understudied as devices used by actors to induce policy change. This paper explores the role of models in Danish economic policy, where, from the 1970s onwards, executive public servants in this area have exclusively been specialists in model design. To understand changes in economic policy, this paper starts with a discussion of whether the notion of paradigm shift is adequate. It then examines the extent to which the performativity approach can help identify macroscopic changes in policy from seemingly microscopic changes in policy models. The concept of performativity is explored as a means of thinking about the constitution of agency directed at policy change. The paper brings this concept into play by arguing that the “performative” embedding of models in institutions is an important aspect of how paradigm shifts unfold that the current literature has neglected. 相似文献

This paper applies Gini and concentration coefficient decomposition as well as the Foster-Greer-Thorbecke poverty index and the Stark-Yitzhaki welfare index to new data from four villages in Burkina Faso, to compare the marginal effects of remittances from intercontinental and intra-African migration on inequality, poverty and social welfare. Evidence is found that intra-African remittances reduce inequality while intercontinental remittances have the opposite effect. Also, it is found that although remittances from intercontinental migration are associated with much lower incidence, depth and severity of poverty, the marginal impact of remittances from this form of migration on social welfare is limited because recipients do not include the rural poor. 相似文献

Using data from the Philippines, we study the impact of mobile phones on the prices agricultural producers receive for their cash crop. We first look at the impact on price of mobile phone ownership at the household level. Because this masks a considerable amount of heterogeneity, we then look at the impact on price of the intrahousehold allocation of mobile phones. We find that whether the household owns a mobile phone has no impact on price, but whether a farmer or spouse owns a mobile phone is associated with a 5- to 8-per cent increase in price. 相似文献

The rapid spread of modern supply chains in developing countries is profoundly changing the way food is produced and traded. In this article we examine gender issues related to this change. We conceptualise various mechanisms through which women are directly affected, we review existing empirical evidence and add new survey-based evidence. Our results suggest that, although modern supply chains are gendered, their growth is associated with reduced gender inequalities in rural areas. We find that women benefit more and more directly from large-scale estate production and agro-industrial processing, and the creation of employment in these modern agro-industries than from smallholder contract-farming. 相似文献

This study uses pairing of Mexican‐owned manufacturing firms and firms with direct United States investment, to examine the effects of ownership structure on firms’ performance and sources of technology. Results suggest that in terms of profitability, growth and export performance the Mexican firms were competing successfully during the period 1966–73. Furthermore, the basis for this strong posture by the Mexican manufacturers was not due to a heavy reliance on foreign technology imported through formal channels, but rather is linked with internal innovative activity and the use of domestic consultants. 相似文献

This article focuses on the measurement of embodied technological change. It develops the core-machinery approach to capital measurement, which is based on an engineering perspective on technological change. Using technical characteristics of different types of machinery, technical progress in the capital stock can be decomposed into incremental innovation in existing machinery and radical shifts to new technologies. The usefulness of this approach is illustrated by an analysis of embodied technological change in the Indonesian spinning and weaving industries. The core-machinery measure is compared with more traditional measures of the capital stock which are based on price information. Strengths, weaknesses and relevance of the new measure are discussed. 相似文献

This article uses household data from Nepal's two major populated regions (and 27 of 59 districts within those regions) to examine fuelwood consumption and production. In contrast with a purely market assessment, household analysis includes production which is consumed in the producing household. The household regressions yield coefficients and elasticities that are very different from and more reliable than a comparable assessment of market demand and supply. Household results generally support the hypotheses that expenditures on fuelwood are a small share of total household activity and that fuelwood is not sufficiently scarce to alter household behaviour. Fuelwood is sufficiently scarce, however, to alter behaviour for those households in the hill region that do not participate in market exchange. These households may be the best targets for public market interventions designed to alter fuelwood supply and deforestation. 相似文献

Raman spectroscopy has found increased use in the forensic controlled substances laboratory in recent years due to its rapid and nondestructive analysis capabilities. Here, Raman spectroscopy as a screening test for methamphetamine in clandestine laboratory liquid samples is discussed as a way to improve the efficiency of a laboratory by identifying the most probative samples for further workup among multiple samples submitted for analysis. Solutions of methamphetamine in ethanol, diethyl ether, and Coleman fuel were prepared in concentrations ranging from 0.5% to 10% w/v, and Raman spectra of each were collected. A concentration‐dependant Raman peak was observed at 1003 per cm in each solution in 4% w/v and greater solutions. Case samples were analyzed and also found to reliably contain this diagnostic peak when methamphetamine was present. The use of this diagnostic indicator can save the forensic controlled substances laboratory time and materials when analyzing clandestine laboratory liquid submissions. 相似文献

The majority of microfluidic devices used as a platform for low‐cost, rapid DNA analysis are glass devices; however, microchip fabrication in glass is costly and laborious, enhancing the interest in polymeric substrates, such as poly (methyl methacrylate) (PMMA), as an inexpensive alternative. Here, we report amplification in PMMA polymerase chain reaction (PCR) microchips providing full short tandem repeat profiles (16 of 16 loci) in 30–40 min, with peak height ratios and stutter percentages that meet literature threshold requirements. In addition, partial profiles (15 of 16 loci) were generated using an ultrafast PCR method in 17.1 min, representing a ~10‐fold reduction in reaction time as compared to current amplification methods. Finally, a multichamber device was demonstrated to simultaneously amplify one positive, one negative, and five individual samples in 39 min. Although there were instances of loci dropout, this device represents a first step toward a microfluidic system capable of amplifying more than one sample simultaneously. 相似文献
