How can non-profit organisations achieve their intended impact on society? This article analyses factors that influence non-profit action in two key situations: when these organisations work autonomously from the government, and when they work in collaboration with the government. Based on interviews with experienced non-profit leaders in Brazil, the article presents typical paths for success and common reasons for failure in achieving non-profits’ intended outcomes. Organisational, relational and contextual factors influence non-profit action, leading to different outcomes. Brazilian non-profits provide lessons for non-profit action in developing countries contexts that experience cycles of political and economic instability. 相似文献

The conditional cash transfer (CCT) programme Bolsa Família (Family Allowance), introduced in Brazil in 2003, is one of the largest such programmes in the world. Bolsa Família has played a role in the recent reduction of poverty and income inequality in Brazil. But what has been its impact on democracy? An assumption in the literature on social policy, derived from the European experience, is that targeted programmes such as Bolsa Família divide citizens, erode trust between citizens and between citizens and the state, and weaken democracy. This article challenges that assumption, showing that there is considerable evidence that Bolsa Família has strengthened the citizenship rights of the poor and enhanced democracy. The Brazilian experience suggests that, in highly unequal developing countries under conditions of 21st-century capitalism, the argument that targeted social programmes will inevitably undermine democracy is incorrect. 相似文献

Most emerging or re‐emerging infections are vector‐borne or zoonotic and can be disseminated worldwide by infected humans or animals. They are a major public health problem and cause a great impact on economy. Zoonotic outbreaks began to be characterized in the 90s, after the creation of Europol and the FBI. Such investigations are carried by forensic pathologists and other specialists to determine whether an outbreak is natural or deliberate. This review will discuss ten zoonotic outbreaks nonrelated to wars focusing on forensic management. In conclusion, some points should be highlighted in the management of a zoonotic outbreak: (i) its diagnosis and detection by forensic pathologists and the coordination of efforts between other specialists are key factors; (ii) communication guidelines and an efficient healthcare system are crucial for any emergency response; (iii) biosafety of all specialists involved must be guaranteed. 相似文献

Sexual offences by multiple perpetrators are more violent and involve more severe forms of sexual violation than those perpetrated by a lone offender. Often a clear leader exists within these groups. Questions have been raised as to the relative risk of reoffending and the potentially differing criminogenic needs of leaders and followers. However, a recent study comparing leaders and followers in juvenile multiple perpetrator rapes (t'Hart-Kerkhoffs et al., 2011) failed to find some of the expected differences. It was proposed that this might be due, in part, to the way leaders and followers were classified in the study. Before work can progress in this area, it is important to devise reliable and valid means of identifying leaders and followers in multiple perpetrator rape. This article reports on a study which investigated the utility of two different methods of identifying leadership. The Scale of Influence (Porter & Alison, 2001) was applied to a sample of 256 offenders responsible for 95 multiple perpetrator rapes from the United Kingdom. Following this, the relative number of directives uttered by offenders was used to designate leadership. In 66% of the offences sampled, a leader was designated using the number of directives uttered compared with 80% when using the Scale of Influence. When combining both measures to form a composite measure of leadership, this percentage increased to 89%. Classifications of offenders as leaders, followers, and neither, according to the Scale of Influence, the count of directives, and the composite measure, were compared with classifications made by a practitioner to assess their concordance. The composite measure showed the greatest agreement with practitioner opinion. These findings suggest that the Scale of Influence could be developed to take account of other ways that leadership is displayed during multiple perpetrator rapes. 相似文献

Allelic frequencies of 48 informative insert-delete (INDEL) loci were obtained from a sample set of 130 unrelated individuals living in Macapá, a city located in the northern Amazon region, in Brazil. The values of heterozygosity (H), polymorphic information content (PIC), power of discrimination (PD), power of exclusion (PE), matching probability (MP) and typical paternity index (TPI) were calculated and showed the forensic efficiency of these genetic markers. Based on the allele frequency obtained for the population of Macapá, we estimated an interethnic admixture for the three parental groups (European, Native American and African) of, respectively, 50%, 21% and 29%. Comparing these allele frequencies with those of other Brazilian populations and the parental populations, statistically significant distances were found. The interpopulation genetic distance (FST coefficients) to the present database ranged from FST = 0.0431 (p < 0.00001) between Macapá and Belém to FST = 0.266 (p < 0.00001) between Macapá and the Native American group. 相似文献

Forensic age estimation is an important element of anthropological research, as it produces one of the primary sources of data that researchers use to establish the identity of a person living or the identity of unknown bodily remains. The aim of this study was to determine if the chronology of third molar mineralization could be an accurate indicator of estimated age in a sample Brazilian population. If so, mineralization could determine the probability of an individual being 18 years or older. The study evaluated 407 panoramic radiographs of males and females from the past 5 years in order to assess the mineralization status of the mandibular third molars. The evaluation was carried out using an adaptation of Demirjian's system. The results indicated a strong correlation between chronological age and the mineralization of the mandibular third molars. The results indicated that modern Brazilian generation tends to demonstrate an earlier mandibular third molar mineralization than older Brazilian generation and people of other nationalities. Males reached developmental stages slightly earlier than females, but statistically significant differences between the sex were not found. The probability that an individual with third molar mineralization stage H had reached an age of 18 years or older was 96.8-98.6% for males and females, respectively. 相似文献

As part of a long-term project on Northeastern Brazilians, population genetic data were obtained from 323 unrelated individuals from the state of Paraíba. The loci studied were CSF1P0, TPOX, TH01, vWA, D16S539, D7S820, D13S317, D18S51, D21S11, D8S1179, F13A01, F13B and LPL. Their distributions are in Hardy-Weinberg equilibrium. Forensic parameters were calculated and a comparison was made with geographically nearby populations. 相似文献
