What happens to a country's system of labor laws when its government embraces market‐oriented reforms? In a twist on the prediction that labor regulations will be repealed, researchers find that laws remain in place but are not faithfully enforced, a phenomenon known as de facto flexibility. This article examines the case of Brazil to understand its near‐opposite; namely, resilience and renewal in the enforcement of labor regulations. It finds that labor unions have combined the corporatist authority they gained under state control with the autonomy they acquired under democratization to devise new modes of action and to safeguard existing regulations. Meanwhile, labor inspectors and prosecutors rely on existing laws to combat precarious work conditions and promote formal employment relations, which strengthen the unions. This mutually supportive arrangement is neither perfect nor free of tension, but it shows how workers can be protected even when employers are subjected to global competition. 相似文献

This article features the personal experiences of a young African woman victim of trafficking and smuggling from Nigeria to Italy. The aim of the article is to provide a counter-narrative on the phenomenon of human trafficking, by engaging with the youth’s lived experiences. The story forms part of a wider database of youth counter-narratives, gathered by the authors in different parts of the world (Italy, South Africa, and Ethiopia). The narrative will be discussed on the basis of four identified elements, and the reflection addresses them within the wider context of trafficking, smuggling, and human migration. The conclusion drawn is that the language of youth counter-narratives can represent a useful tool to address the complexity of social issues, in particular when they refer to lived experiences of youngsters who have been subjected to different forms of oppression and violence. It also represents a sort of liberation from cultural homogenisation, forcing the readers to engage with a “new humanism.” 相似文献

AbstractThis paper examines two education programmes in Sri Lanka: the Programme for School Improvement (PSI), which decentralises decision-making power, and the School Report Card Programme (SRCP), which was designed to provide parents and other community members with information on the characteristics and performance of their local schools. Using a difference in differences identification strategy, it finds the following results. First, the PSI programme significantly increased Math and English reading test scores among Grade 4 students, but not first language (Sinhalese or Tamil) test scores. However, PSI has had no effect on any test scores of Grade 8 students. In contrast, the SRCP had no significant impacts on any test scores in either grade, and further inquiries revealed that the SRCP was never really implemented. Second, the paper examined the impact of both programmes on teacher and school principal variables. Overall, few effects were found, and in some cases effects were found that one would associate with reduced school quality. On a more positive note, the PSI programme does appear to have led schools to form School Development Committees (SDCs), as the programme stipulates, to establish a list of school priorities and to implement projects funded through local fundraising. 相似文献

Identification of Different Forms of Cocaine and Substances Used in Adulteration Using Near‐infrared Raman Spectroscopy and Infrared Absorption Spectroscopy 下载免费PDF全文

Identification of cocaine and subsequent quantification immediately after seizure are problems for the police in developing countries such as Brazil. This work proposes a comparison between the Raman and FT‐IR techniques as methods to identify cocaine, the adulterants used to increase volume, and possible degradation products in samples seized by the police. Near‐infrared Raman spectra (785 nm excitation, 10 sec exposure time) and FT‐IR‐ATR spectra were obtained from different samples of street cocaine and some substances commonly used as adulterants. Freebase powder, hydrochloride powder, and crack rock can be distinguished by both Raman and FT‐IR spectroscopies, revealing differences in their chemical structure. Most of the samples showed characteristic peaks of degradation products such as benzoylecgonine and benzoic acid, and some presented evidence of adulteration with aluminum sulfate and sodium carbonate. Raman spectroscopy is better than FT‐IR for identifying benzoic acid and inorganic adulterants in cocaine. 相似文献

With China’s naval expansion in the South China Sea, the Philippine government has eased up its counter-insurgency/counter-terrorism campaign and has vigorously pursued instead the modernization of the Armed Forces of the Philippines (AFP) particularly in developing the deterrence capability of the Philippine Navy (PN). However, slow-paced and hampered by scant resources, the naval build-up will hardly deter China’s encroachment on the Philippine maritime territory. Faced with this predicament, the Philippines has resorted to forging new security partnerships with the United States and Japan, two major naval powers in East Asia. The paper concludes that maritime security will remain the Philippines’ priority concern way into the third decade of the 21st century. 相似文献

The objective of this study is to assess the performance of an innovative AI-powered tool for sex determination using panoramic radiographs (PR) and to explore factors affecting the performance of the convolutional neural network (CNN). The study involved 207,946 panoramic dental X-rays and their corresponding reports from 15 clinical centers in São Paulo, Brazil. The PRs were acquired with four different devices, and 58% of the patients were female. Data preprocessing included anonymizing the exams, extracting pertinent information from the reports, such as sex, age, type of dentition, and number of missing teeth, and organizing the data into a PostgreSQL database. Two neural network architectures, a standard CNN and a ResNet, were utilized for sex classification, with both undergoing hyperparameter tuning and cross-validation to ensure optimal performance. The CNN model achieved 95.02% accuracy in sex estimation, with image resolution being a significant influencing factor. The ResNet model attained over 86% accuracy in subjects older than 6 years and over 96% in those over 16 years. The algorithm performed better on female images, and the area under the curve (AUC) exceeded 96% for most age groups, except the youngest. Accuracy values were also assessed for different dentition types (deciduous, mixed, and permanent) and missing teeth. This study demonstrates the effectiveness of an AI-driven tool for sex determination using PR and emphasizes the role of image resolution, age, and sex in determining the algorithm's performance. 相似文献

This article investigates the impact of direct foreign investment (DFI) on the foreign trade of China. It firstly presents a theoretical discussion of the impact of DFI on foreign trade from both macro and micro-economic views, and then provides an empirical study of the role of foreign-invested enterprises in the foreign trade of China. In particular, this article explores transfer pricing by multinational corporations (MNCs), probing their motivations and latitude to practice transfer pricing in the Chinese particular circumstances and examining empirical evidence. 相似文献
