In this article, we give the asymptotic mean integrated squared error and the mean squared error for the kernel estimator of the hazard rate from truncated and censored data. Martingale techniques and combinatory calculus are used to obtain these results. A probability bound and the optimal bandwidth choice are also given.  相似文献

This paper describes a support group for children, ages 9–13, whose mothers are living with the Human Immunodeficiency Virus (HIV). Beginning with identification of the need for, and purpose of the group, the paper describes the group recruitment, screening and intake process; group composition; group content and process; barriers to service and issues specific to facilitation of the group. The group provided support to children by increasing knowledge of HIV and Acquired Immunodeficiency Syndrome (AIDS) issues, providing a forum for expression of feelings and concerns regarding their parent's HIV status, improving communication skills, identifying and expanding coping strategies, and facilitating peer support for normalization and validation of fears and concerns.  相似文献

We study the blocking probability in a continuous time loss queue, in which resources can be claimed a random time in advance. We identify classes of loss queues where the advance reservation results in increased or decreased blocking probabilities. The lower blocking probabilities are achieved because the system tends to favor short jobs. We provide analytical and numerical results to establish the connection between the system’s parameters and either an increase or decrease of blocking probabilities, compared to the system without reservation.  相似文献

High total organic carbon (TOC) concentrations in Converse Reservoir, a water source for Mobile, Alabama, have concerned water treatment officials due to the potential for disinfection byproduct (DBP) formation. TOC reacts with chlorine during drinking water treatment to form DBPs. This study evaluated how increased urbanization can alter watershed-derived total nitrogen (TN), total phosphorus (TP) and TOC inputs to the Converse Reservoir. Converse Watershed, on the urban fringe of Mobile, is projected to undergo urbanization increasing watershed urban land from 3% in 1992 to 22% urban land by 2020. A pre-urbanization scenario using 1992 land cover was coupled with 2020 projections of land use. The Loading Simulation Program C++ watershed model was used to evaluate changes in nutrient concentrations (mg L?1) and loads (kg) to Converse Reservoir. Urban and suburban growth of 52 km2 simulated from 1991 to 2005 (15 year) caused overall TN and TP loads to increase by 109 and 62%, respectively. Simulated urban growth generally increased monthly flows by 15%, but resulted in lower streamflows (2.9%) during drought months. Results indicate that post-urbanization median TN and TP concentrations were 59 and 66% higher than corresponding pre-urbanization concentrations, whereas TOC concentrations were 16% lower. An increase in urban flow caused TOC loads to increase by 26%, despite lower post-urbanization TOC concentrations.  相似文献

In recent years masculinity studies writers, in particular R. W. Connell, have focused on the relationship between globalization and ‘hegemonic’ forms of masculinity. This paper provides an assessment of this scholarship and argues that whilst Connell and others have usefully identified the gendered nature of globalization, masculinity scholars have also provided a somewhat limiting account of the global hegemonic role of a monolithic top-down ‘transnational business masculinity’. By contrast, we suggest a demassification of this notion of hegemonic masculinity. Such a demassification enables the opening up of a dialogue between masculinity studies and feminist and other critical globalization scholars, allowing for a more nuanced analysis that can attend to both the unevenness of globalization in different settings and more detailed awareness of interactions between global and local/cultural/state imperatives. Our aim here is to move away from conceptualizations of globalization and hegemonic masculinity that are exceptionally top-down towards an analysis of the contested and shifting nature of gender identity at the global as well as the local level, to highlight the ways in which different hegemonic masculinities are negotiated, and even resisted. We argue that by understanding ‘transnational business masculinity’ as a discursive ideal that legitimates the workings of global capitalism, there is scope for a greater level of engagement between critical globalization scholarship and gender studies. This might also open the door to an account of globalization that entails more detailed reference to women and femininities.

En años recientes, los escritores sobre Los Estudios de la Masculinidad, y en particular R.W. Connell, se han enfocado en la relación entre la globalización y las formas ‘hegemónicas’ de la masculinidad. Este artículo proporciona una evaluación de esta beca y sostiene que mientras Connell y otros han identificado de manera útil la naturaleza del género de la globalización, los académicos sobre la masculinidad también suministraron un reporte de cierta manera limitado, sobre el rol hegemónico global monolítico del más alto al más bajo, de ‘una masculinidad en los negocios transnacionales’. Por el contrario, nosotros sugerimos una desmasificación de esta noción de masculinidad hegemónica. Tal desmasificación hace posible la apertura de un diálogo entre Los Estudios de la Masculinidad y de Feministas y otros académicos críticos de la globalización, permitiendo un análisis más matizado que puede acudir tanto a la disparidad de la globalización en diferentes escenarios como a una mayor conciencia detallada sobre las interacciones entre los imperativos locales/culturales/estatales. Nuestra meta es separarnos de las conceptualizaciones de la globalización y de la masculinidad hegemónica que son excepcionalmente jerárquicas hacia un análisis de los controvertidos y trasladar la naturaleza de la identidad del género tanto a nivel global como al local, para resaltar las formas como las masculinidades hegemónicas diferentes han negociado, e incluso resistido. Sostenemos que al entender ‘la masculinidad en los negocios transnacionales’ como un ideal discursivo que legitimiza el funcionamiento del capitalismo global, existe un propósito para un nivel mayor de participación entre la investigación crítica de la globalización y los estudios del género. Esto también puede abrir la puerta a un informe de globalización que conlleve una referencia más detallada de mujeres y feminidades.

We establish the uniform almost-sure convergence of a kernel estimate of the conditional density for an ergodic process. A useful application to the prediction of the ergodic process via the conditional mode function is also given.  相似文献
