We use firm-level panel data for the manufacturing sector in four African countries to investigate whether exporting impacts on efficiency, and whether efficient firms self-select into the export market. Based on simultaneous estimation of a production function and an export regression, our preferred results indicate significant efficiency gains from exporting, which can be interpreted as learning by exporting. We show that modelling unobserved heterogeneity by a flexible approach is important for deriving this conclusion. A policy implication of our results is that Africa would gain from orientating its manufacturing sector towards exporting. 相似文献

This study, which includes a comparison of American experience, focuses on women policing in India. Using a standardized survey questionnaire, data were collected from women officers on line duty in all district police departments in the State of Tamil Nadu, India, and in municipal and sheriff's departments in New Jersey. A discriminant analysis found important differences between the samples in the officer's preferred roles, with more of the officers from Tamil Nadu preferring a traditional role. Other differences were also found between the samples in terms of deployment experience, career commitment, perceived interests and perceived capability in performing various tasks compared with male officers. These differences appeared to be due to both organizational and cultural factors. 相似文献

Since the seminal Sex Discrimination Act 1975, modern British equality law developed in a piecemeal fashion over four decades. The landmark Equality Act 2010 was designed to unify, simplify and, to a limited extent, strengthen the legislation in this area. Despite its long gestation period, the Bill suffered from a lack of parliamentary scrutiny. This article sets the Equality Act in context and, by analysing certain aspects, discusses how far it has met those aims. 相似文献

Red spray paints from different European suppliers were characterised to determine the discriminating power of a sequence of analysing techniques. A total of 51 red spray paints were analysed with the help of three techniques: (1) optical microscopy, (2) Fourier transform infrared spectrometry and (3) X-ray fluorescence. Infrared spectra were classified according to binder type, filler and pigment composition and a searchable spectral library was created. Due to the difference in the elemental composition of spray paints, a further discrimination was possible. The microscopic analysis was not taken into consideration for classification purposes. The structure of the substrate under a paint coating strongly affects the surface characteristics of this spray paint. Together with the spectral library, a database of information of spray paints was build. 相似文献

Abstract: Poisoning with superwarfarins, like bromadiolone, is a growing public health problem, and the mortality is high. Pharmacokinetic data on bromadiolone in humans are however scarce, and there are no reports following repeated exposures to bromadiolone. We have developed a method for quantification of bromadiolone in whole blood, using liquid chromatography–mass spectrometry (LC-MS). The analytical method is reported. Limit of detection was 0.005 mg/L and limit of quantification was 0.01 mg/L. The concentrations of bromadiolone in whole blood and plasma in serial samples from a 62-year-old woman were measured. The half-life of bromadiolone in blood was estimated to be about 6 days in the initial phase of elimination and about 10–13 days in the terminal phase. The mean plasma/blood ratio of bromadiolone was 1.7 ± 0.6. Stability testing of bromadiolone in whole blood samples after two cycles of freeze and thaw revealed that bromadiolone concentrations decreased. 相似文献

Despite its endorsement by the Treaty of Amsterdam, the origins and content of the 'common travel area' between Britain and Ireland remain largely unknown. This article relies upon published and archive material in order to provide a comprehensive analysis of the common travel area. It shows that the common travel area has been founded upon administrative agreements (in 1922 and 1952), that it has influenced the special status of Irish nationals in British law and vice versa, and that it has been reflected in the law on entry to each state from the other and in the enforcement by each state of the other's immigration policy. It goes on to argue that the existence of a land border between the two states has been the primary reason for the common travel area. The implications for the common travel area of the recent increase in immigration to Ireland are then examined. Here, it is shown there have been significant changes to Irish immigration law relating to the common travel area since 1997, and it is suggested that these new circumstances may result in further reform of laws and practices in both Britain and Ireland. 相似文献

Comparisons among electoral systems: Distinguishing between localism and candidate-centered politics
Carey and Shugart (1995) offer a four component composite index of “incentives to cultivate a personal vote.” We argue that this index, while tapping important aspects of electoral system choice, is best regarded as encompassing two distinct dimensions: degree of party-centeredness of the electoral system, on the one hand, and incentives for “parochial” behavior on the part of legislators, on the other. Also, while we have no problem with the three indicators used by Carey and Shugart to measure party-centeredness; to measure parochial incentives we prefer to use a new measure, E (Grofman, 1999a) of the size of a legislator's electoral constituency, rather than using district magnitude, m, as a proxy for a the size of a legislator's geographic constituency, as Carey and Shugart do. In the conclusion to the paper we argue that the degree of similarity between any two electoral systems will depend upon the research question at issue, and that the expected degree of proportionality of election results is only one of the many political consequences of electoral laws to which we ought to be paying attention. 相似文献
