Crime or disease surveillance commonly rely in space-time clustering methods to identify emerging patterns. The goal is to detect spatial-temporal clusters as soon as possible after its occurrence and to control the rate of false alarms. With this in mind, a spatio-temporal multiple cluster detection method was developed as an extension of a previous proposal based on a spatial version of the Shiryaev–Roberts statistic. Besides the capability of multiple cluster detection, the method have less input parameter than the previous proposal making its use more intuitive to practitioners. To evaluate the new methodology a simulation study is performed in several scenarios and enlighten many advantages of the proposed method. Finally, we present a case study to a crime data-set in Belo Horizonte, Brazil. 相似文献

Testing for bioequivalence of highly variable drugs from TR‐RT crossover designs with heterogeneous residual variances 下载免费PDF全文
Traditional bioavailability studies assess average bioequivalence (ABE) between the test (T) and reference (R) products under the crossover design with TR and RT sequences. With highly variable (HV) drugs whose intrasubject coefficient of variation in pharmacokinetic measures is 30% or greater, assertion of ABE becomes difficult due to the large sample sizes needed to achieve adequate power. In 2011, the FDA adopted a more relaxed, yet complex, ABE criterion and supplied a procedure to assess this criterion exclusively under TRR‐RTR‐RRT and TRTR‐RTRT designs. However, designs with more than 2 periods are not always feasible. This present work investigates how to evaluate HV drugs under TR‐RT designs. A mixed model with heterogeneous residual variances is used to fit data from TR‐RT designs. Under the assumption of zero subject‐by‐formulation interaction, this basic model is comparable to the FDA‐recommended model for TRR‐RTR‐RRT and TRTR‐RTRT designs, suggesting the conceptual plausibility of our approach. To overcome the distributional dependency among summary statistics of model parameters, we develop statistical tests via the generalized pivotal quantity (GPQ). A real‐world data example is given to illustrate the utility of the resulting procedures. Our simulation study identifies a GPQ‐based testing procedure that evaluates HV drugs under practical TR‐RT designs with desirable type I error rate and reasonable power. In comparison to the FDA's approach, this GPQ‐based procedure gives similar performance when the product's intersubject standard deviation is low (≤0.4) and is most useful when practical considerations restrict the crossover design to 2 periods. 相似文献

Over the last 50 years, increasingly complex care (such as tracheostomy management, dialysis or enteral feeding) has shifted from hospital to home, with a concomitant rise in patient self-management and care given by family members. Recognition of the importance of the contribution of family care to the health system is also growing. This article reports the findings of a New Zealand study which explored the experiences of family carers who manage technical health procedures at home. It then draws attention to some broader issues raised by shifting complex care from professional management in hospital settings to family care at home, namely the ways in which complex home care blurs the boundaries between professional and family care (creating the ambiguous position of the expert carer) and questions of safety and responsibility in family care. We also discuss the implications for policy around family caregiving in New Zealand. Given the potential physical and mental health impacts of caring, it is time for renewed consideration of what family carers should be expected or allowed to manage and how the health system can support them in their important role. 相似文献

ABSTRACTThis article posits that an integrative research partnership model can assist school counselors in addressing the marginalization of transgender students in schools through staff development. A methodological integration of action research and program evaluation through quantitative and qualitative data collection is explained, and a collaborative process is highlighted. A case example is provided to demonstrate the use of the design. 相似文献

Within studies of ageing, rurality and family relations, the prevalent “point of view” is based on the perspectives of adults, particularly older people themselves. However, taking seriously the reciprocal nature of kinship relations also challenges researchers to find ways to explore younger people's views and experiences of intergenerational ties. The study on which this paper is based addressed this challenge, by considering the dynamics of ageing in rural families through the lens of young people's experience. In the South Island of New Zealand, Area Schools serve families in rural regions specifically defined in terms of a catchment area based on distance from any other state school. This research study selected five (from 16) of these schools, and invited the classes of Year 7 and 8 students to take part in a classroom activity, led by the researcher with support from the class teacher. The activity involved a total of 98 young people (aged 11–13) in written completion of a survey which outlined their relationships and contacts with the people they know as grandparents, along with basic demographics of their own age, gender, family and household situation, and length of attendance at the school. From this survey, information was derived about 380 grandparents (of whom 73 were no longer alive), the nature and frequency of their contacts, and the types of activities they shared with these grandchildren. Around 40 percent of the students have daily or weekly contact with a grandparent, one third “regularly do things together”, and one fifth say they have “a special relationship” with a grandparent. By controlling the age group of the grandchild, and focussing on rural families, this study adds insights and detail to a growing body of research interest in understanding the roles and contributions made by grandparents to New Zealand families, in particular those in rural communities. 相似文献

Background: This paper presents the vocational journey of a young British woman, Keeley, who changed her career aspirations to become a mental health worker following an episode of significant mental health difficulties. Keeley's story illustrates the application of the locally developed WORKS framework in conceptualising and supporting Keeley's vocational recovery. Approach: A narrative approach highlights the partnerships that developed between Keeley, the Occupational Therapist, Sally, and the User Support and Employment Service. Findings: The WORKS framework supported Keeley and Sally to collaboratively develop a successful employment pathway. Strategies, including attention to Keeley's view of her capabilities and aspirations, volunteer placements, support of peers, employer engagement and planning for sustainable employment, assisted Keeley to establish her chosen career. Keeley's journey highlights the leadership role that mental health services can assume by providing paid work for people with experience of mental health difficulties. 相似文献
