Staff and youth views on autonomy and emancipation from residential care: A participatory research study

The use of participatory approaches in designing services is still relatively uncommon. In this study, we helped design a service to support the transition of youth from residential care to independent living by exploring the perspectives of staff and of youth regarding: (a) the concept and development of autonomy; and (b) key factors in developing this type of service. We gathered the data through 10 interviews with staff (n = 10) and 4 focus groups with youth (n = 21), and subjected the data to a thematic content analysis. Staff defined autonomy as self-regulation and self-care, and identified three paths to foster autonomy – a sense of normality, meaningful relationships, and planning for emancipation. The staff and youth identified the following important aspects in designing the service: achieving normality (e.g. limited number of residents), promoting youth capacity (e.g. skill-building activities), providing social support (e.g. trust and respect between residents), and assuring guidance and boundaries (e.g. supervision of youth).

On Non-parametric Estimation of the Survival Function with Competing Risks

The non-parametric maximum likelihood estimators (MLEs) are derived for survival functions associated with individual risks or system components in a reliability framework. Lifetimes are observed for systems that contain one or more of those components. Analogous to a competing risks model, the system is assumed to fail upon the first instance of any component failure; i.e. the system is configured in series. For any given risk or component type, the asymptotic distribution is shown to depend explicitly on the unknown survival function of the other risks, as well as the censoring distribution. Survival functions with increasing failure rate are investigated as a special case. The order restricted MLE is shown to be consistent under mild assumptions of the underlying component lifetime distributions.     

Non-Gaussian Ornstein–Uhlenbeck-based models and some of their uses in financial economics

Non-Gaussian processes of Ornstein–Uhlenbeck (OU) type offer the possibility of capturing important distributional deviations from Gaussianity and for flexible modelling of dependence structures. This paper develops this potential, drawing on and extending powerful results from probability theory for applications in statistical analysis. Their power is illustrated by a sustained application of OU processes within the context of finance and econometrics. We construct continuous time stochastic volatility models for financial assets where the volatility processes are superpositions of positive OU processes, and we study these models in relation to financial data and theory.     

Maximum entropy sampling and optimal Bayesian experimental design

When Shannon entropy is used as a criterion in the optimal design of experiments, advantage can be taken of the classical identity representing the joint entropy of parameters and observations as the sum of the marginal entropy of the observations and the preposterior conditional entropy of the parameters. Following previous work in which this idea was used in spatial sampling, the method is applied to standard parameterized Bayesian optimal experimental design. Under suitable conditions, which include non-linear as well as linear regression models, it is shown in a few steps that maximizing the marginal entropy of the sample is equivalent to minimizing the preposterior entropy, the usual Bayesian criterion, thus avoiding the use of conditional distributions. It is shown using this marginal formulation that under normality assumptions every standard model which has a two-point prior distribution on the parameters gives an optimal design supported on a single point. Other results include a new asymptotic formula which applies as the error variance is large and bounds on support size.

Identification of composite (∑+II) arma models by relatively simpler models

In the real world situations, many time series are aggregates of two or more time series. An aggregation may take place due to an addition or the product or both of two or more time series. We are often interested in the study of the properties of aggregates which are, in turn, dependent on the properties of the constituent series. Motivated by this problem, the authors study in this paper the properties of models generated by the operator (Σ+II) on autoregressive-moving-average (ARMA) processes of orders (p_i,q_i), i = l→n . A few practical examples where such models have been used are given in the introduction and an illustrative numerical example is discussed at the end of the paper.

解析设计色彩中“色彩理论”的教授模式

＂色彩理论＂对于艺术设计的理性思维来说是非常重要的。艺术设计是由其特性决定的,具有强烈的目的性。它的最终目的就是要获得在社会生产、分配、交换、消费各领域中满足目标市场,体现多种功能,实现复合价值。色彩理论知识博大深奥,就学生在校时间和色彩课程设置时间而言,全部接触是很困难的。如何使学生主动、有效地接受这些看起来枯燥的＂理论知识＂是值得探讨的。
