Quantitative microbiological risk assessment was used to quantify the risk associated with the exposure to Legionella pneumophila in a whirlpool. Conceptually, air bubbles ascend to the surface, intercepting Legionella from the traversed water. At the surface the bubble bursts into dominantly noninhalable jet drops and inhalable film drops. Assuming that film drops carry half of the intercepted Legionella, a total of four (95% interval: 1–9) and 4.5×104 (4.4×104 – 4.7×104) cfu/min were estimated to be aerosolized for concentrations of 1 and 1,000 legionellas per liter, respectively. Using a dose‐response model for guinea pigs to represent humans, infection risks for active whirlpool use with 100 cfu/L water for 15 minutes were 0.29 (~0.11–0.48) for susceptible males and 0.22 (~0.06–0.42) for susceptible females. A L. pneumophila concentration of ≥1,000 cfu/L water was estimated to nearly always cause an infection (mean: 0.95; 95% interval: 0.9–~1). Estimated infection risks were time‐dependent, ranging from 0.02 (0–0.11) for 1‐minute exposures to 0.93 (0.86–0.97) for 2‐hour exposures when the L. pneumophila concentration was 100 cfu/L water. Pool water in Dutch bathing establishments should contain <100 cfu Legionella/L water. This study suggests that stricter provisions might be required to assure adequate public health protection.  相似文献

The article provides an in‐depth analysis of the gendering processes among PhD candidates in a political science department. It uses Joan Acker's theory of gendered organizations operating through four dimensions: the gendered division of labour, gendered interaction, gendered symbols and gendered interpretations of one's position in the organization. The article combines this approach with theories of hidden discrimination. The key theoretical aim is to contribute to gendered organizational theory by examining the ways in which hidden discrimination and the gendered organization work together. This generates detailed and differentiated knowledge about the mechanisms of hidden discrimination that produce gender inequalities in the department. The findings presented in this article point to the role of gendered division of labour and the lack of information about departmental practices. PhD supervision by men is a particularly strong structural barrier for women because of the gendered nature of interaction in supervision and the difficulties that female PhD students have in a male‐dominated environment. The article further contributes to debates on gendered organizations by focusing upon the gendered symbols of expertise in political science. These symbols reproduce the man as the political scientist norm and result in women interpreting their own position as marginal or as outsiders.  相似文献

This article proposes a new model for right‐censored survival data with multi‐level clustering based on the hierarchical Kendall copula model of Brechmann (2014) with Archimedean clusters. This model accommodates clusters of unequal size and multiple clustering levels, without imposing any structural conditions on the parameters or on the copulas used at various levels of the hierarchy. A step‐wise estimation procedure is proposed and shown to yield consistent and asymptotically Gaussian estimates under mild regularity conditions. The model fitting is based on multiple imputation, given that the censoring rate increases with the level of the hierarchy. To check the model assumption of Archimedean dependence, a goodness‐of test is developed. The finite‐sample performance of the proposed estimators and of the goodness‐of‐fit test is investigated through simulations. The new model is applied to data from the study of chronic granulomatous disease. The Canadian Journal of Statistics 47: 182–203; 2019 © 2019 Statistical Society of Canada  相似文献

Individual development accounts (IDAs), wealth-building programs for the working poor, have existed since the late 1980s. Current research suggests that IDA programs benefit families while contributing to local and state economies. This program evaluation assessed the impact of one state Temporary Assistance for Needy Families (TANF)-funded IDA initiative. Quantitative and qualitative data were collected from four agencies chosen using cluster sampling across the state. Agency programmatic and participant data from the last year of operation (N?=?160) were examined. Agencies also provided contact information for three participants who had graduated and three who exited the program prematurely in the past year of operation. In person, interviews were held with agency directors (n?=?6) and IDA participants (n?=?11) were interviewed by telephone. Results indicate that 69% (n?=?111) of IDA enrollees successfully completed the program. IDA participants who exited the program prior to completion also expressed benefits associated with the time in which they were involved. Programmatic and individual benefits and challenges reported guide recommendations for improving IDA marketability, participant outcomes, and organizational performance rates. A critical implication of the findings is the need to expand the use and design of IDA programs legislatively to better serve historically oppressed and working poor families more effectively.  相似文献

Although many children across cultures are victims of physical abuse, few treatment models target these children and their parents. In Sweden, Combined Parent–Child Cognitive Behavioural Therapy for families at risk for child physical abuse has been successfully used according to pretreatment and posttreatment studies. However, few studies have explored how physically abused children experience treatment. This study includes 20 physically abused children aged 9–17 who completed Combined Parent–Child Cognitive Behavioural Therapy. Children had a positive overall impression of the treatment and highlighted addressing the abuse, as well as processing their experiences as particularly essential. Children described a positive transformation in their family life as a result of treatment, including violence cessation and bonding among family members. Children experienced the intervention as inclusive and child‐friendly. The implications of the promising findings are discussed.  相似文献

Alongside the ongoing renewal process of the Finnish welfare state, the role of the citizens is also revisited. So far the attention has mainly focused on how the responsibility for service provision is shared between the public sector and the service users, while the role of public services as a part of the democratic system has been more or less ignored. Based on the results from a 3-year participatory action research project called KAMPA, this article will discuss if the development of co-production in the context of public welfare services shows the way forward toward a new kind of society where democracy is an inseparable part of the structures and procedures of the service provision. The data gathered during the project (textual material, interviews, notes from meetings, and observation diaries) are analyzed using thematic analysis. The results show that while legislation and official policies strongly highlight the participation of citizens and service users, there are still many obstacles to overcome at both the attitudinal and practical level. The development of co-production and arenas of a new kind of democracy requires continuity in the attempts and recognition of the achievements, but it also has the potential to demonstrate the way in which a new more lively democratic society can come true in practice.  相似文献

Investing in community leadership development (CLD) remains a strategy with promise in creating vibrant communities. Although many low-income CLD programs teach effective leadership skills, these often lay fallow due to lacking opportunities for graduates to apply the skills. This study explores how providing competitive minigrants fuels the creation of value-adding community projects. In-depth interviews were conducted with 55 graduates of a low-income CLD program, 19 facilitators, and 12 community members knowledgeable about the program. The study observed that by providing seed money for graduate projects, CLD programs can help translate skills into practice thereby increasing community engagement and socio-economic wellbeing.  相似文献

Public relations ethics is confused and often superficial in its approach, relying heavily on traditional theory, with only occasional reference to more recent developments in professional ethics, particularly feminist and global ethical perspectives.  相似文献
