Diversity of vascular plants growing on walls of a Brazilian city   总被引:2,自引:0,他引:2  
City walls are very specialized environments, conditioned by human activities. There is little information about plants that invade human-made habitats, and no study done in Brazil with plants growing up on walls. The aim of the present study was to survey the wall vascular flora of a Brazilian city, comparing the diversity found in its downtown and neighborhoods. Fieldwork was done in Jundiaí, São Paulo State, where data was collected in downtown and in five neighborhoods. In each place, three transects of 1 km were established and every plant individual was registered. Twenty-eight species were identified, all of them on the downtown transect and most also on the neighborhood transects. Five species were the most frequent, although none were dominant. The diversity indicies of the six transects were not significantly different, with an overall diversity of H′ = 2.93.  相似文献

Abstract   This article describes and assesses indicators of social security coverage in Brazil over the period 1992 to 2006 for employed workers and the elderly. While the coverage of retired workers has shown some degree of stability over the past years, that of employed workers changed significantly over the period, showing clear signs of deterioration between 1992 and 2002, and of recovery since then. Fewer self-employed persons in agriculture in rural areas (Special Insured Persons, workers with specific social security schemes) accounts for most of the deterioration. The economic recovery and an increase in new registered jobs accounts for most of the improvement in coverage between 2003 and 2006. Administrative and institutional factors also played a relevant role, especially in promoting the inclusion of domestic and self-employed workers as social security contributors.  相似文献

Political changes related to globalization apparently produce similar effects on old and new democracies. All over the world, comparative research on democratization has showed that political distrust is a common variable affecting the whole of the State and the relationship between citizens and democracy. Nevertheless, political discontent in old democracies has stimulated citizens to adopt new attitudes and modes of political participation, while in newly democratized countries citizens tend to withdraw from politics as a consequence of institutional distrust. In fact, in many new democracies, although adhering to the normative meaning of the democratic regime, distrust of democratic institutions is associated to citizens’ negative feeling about political efficacy, low levels of political interest and political participation, and also preference for democratic models which exclude political parties and/or parliaments. This paper evaluates the meanings and consequences of the contemporary phenomenon of political discontent in Brazil and Latin America and discusses its implications for democratic theory.  相似文献

ABSTRACT

Analysis of Brazil’s political and economic crisis tends to emphasize the economic ‘errors’ that President Dilma Rousseff’s Workers’ Party (PT) government inherited from her predecessor Luíz Inácio Lula da Silva. It is clear, however, that political regulation is too narrow a focus to understand the current crisis. Such an explanation is unable to reveal the changes in class structure that took place during the Lula era as well as the effects of the international economic crisis. This article identifies the limits of the Brazilian development model and the main features of Lula’s mode of regulation; analyses the conflicts produced by the neo-liberal regime of accumulation and the Lulista mode of regulation, emphasizing the role of precarious work in the current historical cycle of strikes and popular struggles in Brazil; and, finally, interprets the palace coup promoted by the social forces behind the impeachment of President Rousseff.  相似文献

This article focuses on an analysis of social insurance models and reforms in Chile, Uruguay and Brazil. Noting that these three countries are following different reform trajectories, the article explores trends in the restructuring of each of these insurance systems across the course of successive reforms. In the systems, different trends are supporting a closer link between contributions and benefits, according growing importance to private individual accounts and favouring the expansion of the role played by social assistance. These trends all suggest a move towards various forms of multi‐pillared social insurance, but with uncertain results in terms of redistribution and the dynamics of the fundamental objectives of social insurance.  相似文献

Parental wealth – as distinct from income, education and other parental socioeconomic resources – may play a large role in children's socioeconomic outcomes, particularly in developing countries, characterized by economic volatility, a weak social safety net and limited access to credit. Using a propensity score matching approach, we examine the influence of parental wealth on adult children's schooling, school quality, occupational status, consumption level, and wealth holdings in Brazil. Findings suggest a substantial effect of parental wealth on all these outcomes, with a positive effect of even modest levels of wealth. The effect of parental wealth on occupational status is largely mediated by parental investment in more and better education for children. In contrast, the effect on children's consumption and wealth is largely unmediated by labor market resources and rewards, a pattern that is more pronounced for sons than for daughters. This suggests direct parental financial assistance. Sensitivity analysis indicates that hidden bias emerging from unobserved confounders should have to be unlikely large to question inference of a causal influence of high levels of parental wealth, although the influence of low levels of wealth may be more susceptible to hidden bias.  相似文献

Shaped by inconsistent policy decisions, the COVID-19 pandemic in Brazil has made structural gender and racial inequalities more acute. Black and low-income women are overburdened with unpaid domestic work, increased domestic violence, and more vulnerable due to informal and exploitative working regimes. These structural aspects are intensifying, since the pandemic has broadened inequalities at the intersection of gender, race, labor market, and social class. We examine pre- and during pandemic inequalities on three dimensions: (a) unpaid domestic and care work, (b) women's labor market participation, and (c) domestic violence. We link the care diamond model and racial stratification forwarding a feminist perspective by examining how the interlocking of race and gender in Brazil renders different socioeconomic dynamics to the detriment of Black and low-income women. Based on this evidence, we stress that a more equal future requires a better social protection and policies targeting the articulation of gender, race, and class.  相似文献

Brazil has entered the world of development assistance, but with its own twist. This article argues that Brazil is taking a cross‐government policy approach to the provision of development assistance, and which includes recruitment of business interests. There is a genuine concern with global poverty alleviation in Brazil, but this does not preclude policy‐makers from using aid and development‐related activities to advance national interests. The added quirk that sets Brazil apart from Northern counterparts is that the provision of development assistance offers significant benefits in terms of building up international bureaucratic experience inside the country and helping national firms internationalise their market activities.  相似文献

We use census data to investigate fertility change across more than 500 Brazilian microregions during 1970–2000, before and after controlling for local covariates. We use semivariograms to analyze spatial patterns, in order to investigate the importance of diffusion or social interaction in the spread of fertility transition across a map. Our analysis shows that spatial patterns in Brazilian fertility change are strongly related to spatial patterns in measurable local conditions such as electrification, child mortality, and female education. Differences in local conditions are particularly good at explaining spatial correlations at distances >500 km. At shorter distances, there remains some unexplained spatial correlation in fertility change that could be attributed to diffusion or social interaction.  相似文献
