National Park of Tijuca in Rio de Janeiro (Brazil) is about 3,300 ha and considered the largest urban forest in the world. Its floristic composition is typical of Atlantic Rain Forest. The reserve is being altered because of fire occurrences and urban expansion. This study identified locations and causes of forest fires, and makes management recommendations to restore damaged areas. From 1991 to 2000, forest firefighters recorded an average of 75-fire occurrences/year. Identified causes included hot air balloons (24%), intentional (24%), rubbish burning (21%) and religious practices (17%). Primary fuels included invasive grasses and ferns. Although hot air balloons destroyed larger areas of forest in each occurrence, a greater number of fires started in the invasive vegetation along roads that bisect the forest. In response to recurrent forests, invasive vegetation has spread gradually into the forest increasing forest degradation. To decrease fire damage, sites with high fire frequencies and density of invasive vegetation were planted with less flammable species. Results indicate that fire frequency decreased and density of invasive vegetation declined. This approach appears to prevent fire incidence, reduce the need for fire fighting, and preserve existing biodiversity.  相似文献

Summary.  During the early 1990s the proportion of a cohort entering higher education in the UK doubled over a short period of time. The paper investigates the effect of the expansion on graduates' early labour market attainment, focusing on overeducation. We define overeducation by combining occupation codes and a self-reported measure for the appropriateness of the match between qualification and the job. We therefore define three groups of graduates: matched, apparently overeducated and genuinely overeducated. This measure is well correlated with alternative definitions of overeducation. Comparing pre- and post-expansion cohorts of graduates, we find with this measure that the proportion of overeducated graduates has doubled, even though overeducation wage penalties have remained stable. We do not find that type of institution affects the probability of genuine overeducation. Apparently overeducated graduates are mostly indistinguishable from matched graduates, whereas genuinely overeducated graduates principally lack non-academic skills and suffer a large wage penalty. Individual unobserved heterogeneity differs between the three groups of graduates but controlling for it does not alter these conclusions.  相似文献

Gifted individuals face many concerns when contemplating their futures. Often hindered by career indecision; perfectionism; and multiple personal, familial, and societal pressures, some gifted young people flounder when they have the ability to flourish. Many counselors and educators trust that a wealth of talents will propel these adolescents to automatic life success, and the unique needs of this population can go unmet. This article considers the complexity of challenges facing gifted young women, presents current and potential interventions, and encourages integrating developmental and constructivist theories with objectivist techniques. Implications for practitioners and future research suggestions are highlighted.  相似文献

The Poverty Reduction Strategy of the Ugandan Government identified provision of microfinance as one of its interventions. Despite the known connection between poverty and people with disabilities, it remains unclear to what extent this intervention includes or accommodates them. This study seeks to gain a better understanding of how people with physical and sensory disabilities access existing microfinance services in the Bushenyi District of Uganda. Qualitative and quantitative methodologies are used. The findings suggest that people with disabilities are not necessarily denied access to microfinance if they meet the desired requirements. These relate to adequate savings or collateral and perceived trustworthiness. These are seen to be key determinants of success and can be linked to impaired functioning relating to limited mobility, distance, poorer access to information and disabled people’s own negative attitudes. Increasing access and utilization of microfinance services by people with disabilities requires formulation of financial policies that accord them special consideration. At the same time, improvement is needed in the knowledge, attitudes and skills of the people with disabilities themselves and also microfinance providers.  相似文献

The constant decline of political trust has been shown in political sociology. Young people in particular seem to display lower levels of political trust, which is a challenge for the sustainability of democracy. Still, these levels of political trust among youth differ greatly from one country to another. This article therefore seeks to answer the following question: How can we account for cross‐national diversity with regard to young people’s political trust? To answer this question, I performed multilevel analyses based on data from the European Social Survey. I show in the article that cross‐national diversity stems from the institutional arrangements that structure entry into adulthood, i.e., what I call ‘youth welfare citizenship regimes’: The more inclusive is the youth economic citizenship and the more individualised is their social citizenship, the higher is young people’s political trust – which could buffer the decline in political trust.  相似文献

This study examined the relative effects of intimate partner physical and sexual violence on Post-Traumatic Stress Disorder (PTSD) symptomatology. Severity of physical and sexual violence as well as PTSD severity were assessed in a sample of 62 help-seeking battered women. The results of this study were consistent with prior research, finding significant and positive relationships between physical and sexual violence as well as sexual violence and PTSD symptoms. In order to further clarify these relationships, the unique effects of sexual violence on PTSD were examined after controlling for physical violence severity. Results indicated that sexual violence severity explained a significant proportion of the variance in PTSD severity beyond that which was already accounted for by physical violence severity. These findings have important implications for mental health and social service professionals who work with battered women.  相似文献

The long-run labour market consequences of teenage motherhood in Britain   总被引:2,自引:0,他引:2  
Common wisdom states that teenage childbearing reduces schooling, labour market experience and adult wages. However, the decisions to be a teenage mother, to quit school, and be less attached to the labour market might all stem from some personal or family characteristics.  Using the National Child Development Study (NCDS), we find that in Britain teenage childbearing decreases the probability of post-16 schooling by 12–24%. Employment experience is reduced by up to three years, and the adult pay differential ranges from 5% to 22%. The negative impact of teen motherhood on various adult outcomes is not only due to some pre-motherhood characteristics; hence policies aiming to encourage return to school and participation in the labour market may be an efficient way to reduce the long-term consequences of teenage pregnancy.
