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

ABSTRACT

The Aging Semantic Differential (ASD) is the most widely used instrument to measure young people’s attitudes towards older adults. This study translated the ASD to Mandarin and examined its psychometric properties. The Mandarin-ASD contains three latent factors (Personality and Mental Health, Societal Participation, and Physical) that have high internal reliability and reasonable discriminate validity. Social work researchers, practitioners and allied professionals may utilize the ASD-Mandarin instrument to measure young people’s attitudes towards older adults in China. We issue a call for a universal-ASD that can be applied across different cultural contexts.  相似文献

This article assesses how two key institutions differentially shape immigrants’ relationship to their rights in American society. We draw on over 200 in‐depth interviews to argue that there is a stark difference between how schools encourage undocumented youth to view themselves as equal members of US society and how undocumented workers are marginalized in the workplace. We find that even as schools track and stratify students, they also foster a culture of meritocracy between documented and undocumented youth. Schools ultimately render immigration status irrelevant as undocumented youth learn to navigate the primary institution of this stage of their lives. Conversely, immigration status is central to the experience of undocumented workers, who develop a particular set of survival skills that help them live and work successfully in the United States without being detected while also erecting a barrier between themselves and any additional rights they may be afforded.  相似文献

Using data from the 1990 and 2000 U.S. Census of Population and Housing, we examine five social and economic characteristics of individuals and households living on reservations in Arizona and New Mexico that have a casino to those that do not. This research differs in two ways from previous studies that have attempted to assess the social and economic impacts of Indian gaming. First, the unit of observation and analysis is the reservation, not a tribe. A focus on reservations allows us to assess the role casinos play in “place-based” economic development. Second, since reservations and tribes are not coterminous, we seek to differentiate the effects of casinos on the Indian population living on reservations from the effects for all reservation residents (Indians and others). The results show that casino gambling is associated with improvements in social and economic welfare for both the Indian and non-Indian populations alike. However, Indian gaming did not contribute to positive outcomes in all cases. Indeed, the effects of gaming are filtered through a myriad of structural and cultural contexts that shape who wins and who loses when a casino opens on a reservation. The implications of Indian gaming for economic development are discussed.  相似文献

The US population is aging. Traditional perspectives have emphasized that a substantial increase in the number of gerontological social workers is needed to care for this population. However, published evidence demonstrates that, along with population growth, economic and social factors must be taken into account before predicting future gerontological social work demand. Structural lag theory is introduced to explain how these factors affect the profession and may limit its presence in gerontological work settings. Recommendations are made to correct the lag, allowing the social work profession a more substantive voice in the aging enterprise.  相似文献

Mexican American adolescents face disparities in mental health and academic achievement, perhaps in part because of discrimination experiences. However, culturally related values, fostered by ethnic pride and socialization, may serve to mitigate the negative impact of discrimination. Guided by the Stress Process Model, the current study examined risk and protective processes using a 2‐wave multi‐informant study with 750 Mexican American families. Specifically, we examined 2 possible mechanisms by which Mexican American values may support positive outcomes in the context of discrimination: as a protective factor (moderator) or risk reducer (mediator). Analyses supported the role of Mexican American values as a risk reducer. This study underscores the importance of examining multiple mechanisms of protective processes in understanding Mexican American adolescent resilience.  相似文献

In the United States, 5.3 million children and adolescents are growing up either with unauthorized status or with at least one parent who has that status. Until recently, little in the way of research has informed federal, state, and local policy debates related to unauthorized status (e.g., border enforcement, deportation, and a pathway to citizenship) although these issues have important implications for youth development. This statement is a brief summary of the research evidence on multiple domains of development that may be affected by the child or parent's unauthorized status. We also describe the contextual and psychological mechanisms that may link this status to developmental outcomes. We summarize a range of policies and practices that could reduce the developmental harm to children, youth, and their families stemming from this status. Finally, we conclude with recommendations for policy, practice, and research that are based on the evidence reviewed.  相似文献
