This article reports on a project involving the development and release of an ethnographic film about the women divers of Atauro Island, Timor-Leste, and suggests a theoretical framework to interpret its outcomes. It describes the project aims and the filmmaking process, and reports on its results. In doing so, the paper explores the potential use of an agent-based concept of narrative capital focused on collective agents. The article suggests that the ideas of narrative capital and transformations of capital by collective agents can provide a valuable interpretative framework for the design, implementation, and analyses of results of development interventions involving filmmaking.  相似文献

The success of electronic filing services largely depends on their continuance usage. This study examines the factors affecting the continuance usage intention of the online tax filing services in Mauritius. An integrated model comprising Trust Theory and Information System Success Model (ISSM) is applied to assess the continuance usage behaviour of e-filing systems. The model has been extended by adding two additional variables: Perceived Usefulness and Perceived Risk. The model was tested using a sample of 315 users of e-filing services in Mauritius. A structural equation modelling technique using partial least square structural equation modelling verified the hypotheses. The results reveal that the continuance usage intention of an electronic tax filing system is influenced by Perceived Usefulness, User Satisfaction, and Service Quality. However, Perceived Risk does not influence the continuance usage intention of e-filing systems since the importance of Perceived Risk diminishes as trust in the e-service provider increases. The theoretical and practical implications derived from the findings of this study are also discussed. This paper makes several contributions to the literature on electronic tax filing systems.  相似文献

苏联解体后,资本主义的思想家和代表人物不遗余力地宣扬所谓资本主义对社会主义的最终胜利。弗朗西斯·福山宣称这是“意识形态的终结”。英国工党理论家安东尼·戈登斯下结论说,“作为一种经济管理制度,社会主义已经不复存在”。  相似文献

Now that racism has been officially recognized in Brazil, and some universities have adopted affirmative-action admission policies, measures of the magnitude of racial inequality and analyses that identify the factors associated with changes in racial disparities over time assume particular relevance to the conduct of public debate. This study uses census data from 1950 to 2000 to estimate the probability of death in the early years of life, a robust indicator of the standard of living among the white and Afro-Brazilian populations. Associated estimates of the average number of years of life expectancy at birth show that the 6.6-year advantage that the white population enjoyed in the 1950s remained virtually unchanged throughout the second half of the twentieth century, despite the significant improvements that accrued to both racial groups. The application of multivariate techniques to samples selected from the 1960, 1980, and 2000 census enumerations further shows that, controlling for key determinants of child survival, the white mortality advantage persisted and even increased somewhat in 2000. The article discusses evidence of continued racial inequality during an era of deep transformation in social structure, with reference to the challenges of skin color classification in a multiracial society and the evolution of debates about color, class, and discrimination in Brazil.  相似文献

Diphenidine is a dissociative drug that shows several psychotropic effects including euphoria, shifts in perception of reality, hallucinations, and transient anterograde amnesia. In this study, a case of acute intoxication occurring after diphenidine intake is reported. A 30‐year‐old Caucasian male was hospitalized after he was found in a confused and agitated state and unable to communicate. The physical examination displayed tachycardia, miotic pupils, and increased both body temperature and respiratory rate. After a liquid–liquid extraction procedure, GC/MS analysis revealed the presence of diphenidine in plasma and urine at concentrations of 308 and 631 ng/mL, respectively. Methylphenidate and diclazepam were also detected in the plasma. The clinical progress of the patient was favorable, and his symptoms were cured with a symptomatic treatment. The combined circumstantial elements and toxicological results of the case reported revealed the occurrence of an acute intoxication ascribable to the recreational abuse of diphenidine.  相似文献

A fully validated, sensitive and specific method for the extraction and quantification of Delta(9)-tetrahydrocannabinol (THC) and 11-nor-9-carboxy-Delta(9)-THC (THC-COOH) and for the detection of 11-hydroxy-Delta(9)-THC (11-OH THC) in oral fluid, urine and whole blood is presented. Solid-phase extraction and liquid chromatography-mass spectrometry (LC-MS) technique were used, with electrospray ionization. Three ions were monitored for THC and THC-COOH and two for 11-OH THC. The compounds were quantified by selected ion recording of m/z 315.31, 329.18 and 343.16 for THC, 11-OH THC and THC-COOH, respectively, and m/z 318.27 and 346.26 for the deuterated internal standards, THC-d(3) and THC-COOH-d(3), respectively. The method proved to be precise for THC and THC-COOH both in terms of intra-day and inter-day analysis, with intra-day coefficients of variation (CV) less than 6.3, 6.6 and 6.5% for THC in saliva, urine and blood, respectively, and 6.8 and 7.7% for THC-COOH in urine and blood, respectively. Day-to-day CVs were less than 3.5, 4.9 and 11.3% for THC in saliva, urine and blood, respectively, and 6.2 and 6.4% for THC-COOH in urine and blood, respectively. Limits of detection (LOD) were 2 ng/mL for THC in oral fluid and 0.5 ng/mL for THC and THC-COOH and 20 ng/mL for 11-OH THC, in urine and blood. Calibration curves showed a linear relationship for THC and THC-COOH in all samples (r(2)>0.999) within the range investigated. The procedure presented here has high specificity, selectivity and sensitivity. It can be regarded as an alternative method to GC-MS for the confirmation of positive immunoassay test results, and can be used as a suitable analytical tool for the quantification of THC and THC-COOH in oral fluid, urine and/or blood samples.  相似文献

The article seeks to provide a perspective of human trafficking as one of the fastest growing criminal activities of the last few years in the area of organised crime and one that affects human beings’ most basic rights. In the main, the response to the problem has been its criminal prosecution, but without tackling the issues of need that underlie this conduct and which the traffickers take advantage of to abuse, assail and exploit the people they traffic. In this context, the evolution of Spanish legislation in terms of the criminalisation of this problem has made it one of the most repressive, although there is no clear evidence of its effectiveness. This punishment, which covers a wide range of criminal conducts, has not however been accompanied by any policies to support and integrate the victims of trafficking, which has led to a large number of victims being subjected to slavery who, in the majority of cases, fall under the control of the trafficking networks again.  相似文献
