Frontier spaces of vulnerability: Regional change,urbanization, drought and fire hazard in Santarém,Pará, Brazil 总被引:1,自引:1,他引:0
Fire hazard is a mounting concern in tropical rainforests of the Brazilian Amazon and has raised awareness within the science community of the links between agricultural fire use, drought and accidental fire. As a result, fire is being addressed as a crisis event with mitigation focused on those who light fires, particularly smallholder agriculturalists. Little attention is paid to the historical and ongoing ways in which Amazon landscapes and peoples have been made more susceptible to fire. Frontier regions of the Brazilian Amazon serve a variety of functions within the larger Brazilian society, including as extractive reserves for economic development, as social safety valves to reduce population pressures, and as areas to support urban regional integration. Each of these functions has impacted frontier environments in ways that create more flammable landscapes and/or shape the vulnerability of people to fire hazard. This paper uses a case study inthe Brazilian Lower Amazon to understand how vulnerability to fire hazard develops. It argues that if fire mitigation remains centered on fire as a crisis event, an understanding of what constitutes frontier spaces of vulnerability, both in landscape and in populations, will be limited. 相似文献

The evolving democracies of Eastern Europe and the former USSR republics are keenly interested in establishing charities. They have little law on this issue because their former governments did not encourage the development of charities. This article compares US and English regulation of charities and proposes a regulatory framework based on what the authors believe are the best attributes of both. Although the framework is based on the common law system, it can be adapted to the civil law systems of the Eastern European nations and the former USSR republics. The article includes such issues as developing a body of law, tax relief and creating a regulatory agency.Mr Hopkins is a lawyer with Powers, Pyles & Sutter, 1275 Pennsylvania Ave., N.W., Washington, D.C. 20007, and author ofThe Law of Tax-Exempt Organizations (1992a).Ms Moore is also a lawyer, 5908 N. 35th St., Arlington, Virginia 22207.The authors would like to thank Mssrs Kersi Shroff and Stephen F. Clarke, Senior Legal Specialists, American-British Law Division, Library of Congress, and Mr. William H. Morris, an attorney at Steptoe & Johnson, Washington, D.C., for their kind assistance during the researching of this article. 相似文献

In this paper, we present a Bayesian methodology for modelling accelerated lifetime tests under a stress response relationship with a threshold stress. Both Laplace and MCMC methods are considered. The methodology is described in detail for the case when an exponential distribution is assumed to express the behaviour of lifetimes, and a power law model with a threshold stress is assumed as the stress response relationship. We assume vague but proper priors for the parameters of interest. The methodology is illustrated by a accelerated failure test on an electrical insulation film. 相似文献

This paper offers a general overview of past, current, and developing issues and debates in the growing field of gender and feminist media studies. Its main aim is to provide for those who are new to the field, as well as advanced students and researchers, a broad sense of what is now significant and important area of academic research. It engages with the differences and similarities between gender and feminist media studies, gendered communication systems, gendered news production, feminist methodologies and methods in communication research (textual, audience, and production based), the media's role in constructing gender, and gendered and feminist research by specific media form including advertising, magazines, film, television, news, radio, and the Internet and new media. The outline of research presented is not exhaustive; however, it attempts to trace certain significant developments in the field historically, conceptually, methodologically politically and trans‐nationally. 相似文献

In this article, we describe a straightforward method for solving the probability of at least one malignant cell by time t, and the associated hazard function, in the general (i.e., nonhomogeneous) two-stage Moolgavkar-Venzon-Knudson (MVK) model of cancer. The method consists of solving four coupled ordinary differential equations derived from the Kolmogorov backward equations for this process. The relationship of this method to previously proposed solutions is discussed. 相似文献

Risk Modeling, Assessment, and Management of Lahar Flow Threat 总被引:1,自引:0,他引:1
The 1991 eruption of Mount Pinatubo in the Philippines is considered one of the most violent and destructive volcanic activities in the 20th century. Lahar is the Indonesian term for volcanic ash, and lahar flows resulting from the massive amount of volcanic materials deposited on the mountain's slope posed continued post-eruption threats to the surrounding areas, destroying lives, homes, agricultural products, and infrastructures. Risks of lahar flows were identified immediately after the eruption, with scientific data provided by the Philippine Institute of Volcanology, the U.S. Geological Survey, and other research institutions. However, competing political, economic, and social agendas subordinated the importance of scientific information to policy making. Using systemic risk analysis and management, this article addresses the issues of multiple objectives and the effective integration of scientific techniques into the decision-making process. It provides a modeling framework for identifying, prioritizing, and evaluating policies for managing risk. The major considerations are: (1) applying a holistic approach to risk analysis through hierarchical holographic modeling, (2) applying statistical methods to gain insight into the problem of uncertainty in risk assessment, (3) using multiobjective trade-off analysis to address the issue of multiple decisionmakers and stakeholders in the decision-making process, (4) using the conditional expected value of extreme events to complement and supplement the expected value in quantifying risk, and (5) assessing the impacts of multistage decisions. Numerical examples based on ex post data are formulated to illustrate applications to various problems. The resulting framework from this study can serve as a general baseline model for assessing and managing risks of natural disasters, which the Philippines' lead agency-the National Disaster Coordinating Council (NDCC)-and other related organizations can use for their decision-making processes. 相似文献

This article examines entrepreneurs who have started innovative Internet and mobile technology companies in Taiwan because they are at the forefront of industrial changes in the country. Similar to findings in Europe and the USA, education and careers in technology in Taiwan remain dominated by men. However, I argue that the gender inequality of the sector is partly the result of the fact that small new enterprises rely on family support and close social networks. Few women are able to join the sector with male friends and colleagues due to the close social ties of the founding teams (homophily). Among my female interviewees, half have started their nascent companies with their husbands and male partners (husband and wife teams). However, gender, family backgrounds and childcare responsibilities affect both men and women, and the interviewees in my study were open in discussing these personal factors in relation to being entrepreneurs. This article argues that starting an Internet company is a family decision, discussed within the household. Intersectionality, not only gender, explains the founders’ decision to start a company, and their choice of co-founders. 相似文献

Reducing the number of preterm births is a high public health priority in the U.S. Preterm birth, affecting an estimated 380,000 infants annually, is a leading cause of infant mortality and morbidity and is associated with individual and systemic characteristics. Preterm birth is estimated to cost society $26 billion annually. Despite an elevated financial burden caused by preterm birth, very little is known about who bears these costs. This study seeks to understand the relationship between Medicaid and private insurance payment for preterm birth, using multiple years of vital statistics data, which for the first time since 2010 include information on payment source. The nationwide data cover births that occur in all settings, including non-hospital settings, and many maternal characteristics not available in other datasets, improving upon previous analyses. These data can be used to promote better Medicaid coverage of interventions known to be effective in reducing preterm births. 相似文献

Most treatment for gambling disorder is provided on an outpatient basis. Only a small number of jurisdictions in North America provide higher levels of gambling treatment, such as residential or intensive outpatient (IOP) care, despite the potential need for these services. Further, there appear to be few guidelines for determining appropriate level of gambling treatment. The aim of the present study was to assess the appropriateness of higher levels of problem gambling care among clients receiving outpatient treatment. Problem gamblers and their therapists independently completed questionnaires that assessed the need and desire for residential and IOP treatment. About 42% of problem gambling outpatients noted that they would be “probably” or “definitely” willing to attend residential treatment, and about half indicated they would be equally likely to attend IOP. Therapists recommended about a third of their clients as appropriate for higher levels of care. For both client and therapist assessments, there was a significant association between desire or recommendation for level of treatment and severity of gambling and co-occurring problems. Further, therapist recommendations for level of care were significantly associated with client willingness to attend higher levels of treatment. Our data reveal the potential need for higher levels of care for problem gambling, as evaluated by clients and their therapists. Policy implications for the funding of residential and IOP treatment are discussed. 相似文献
