情与貌 略相同——斯奈德与寒山的比较研究

寒山,中国唐代著名隐逸诗人;加里·斯奈德,美国当代著名生态诗人。20世纪50年代,斯奈德翻译的24首寒山诗在美国出版后,影响极大,为寒山诗在美国的流传作出了突出的贡献。斯奈德在生活方式、诗歌创作理念、艺术手法乃至精神境界等诸多方面与寒山不谋而合,或者可以说是寒山的忠实追随者,但二者毕竟生活于不同的时代,受到不同民族文化的熏陶,因而也必然在隐逸观、人生观等方面存在着微妙的差异,进而表露出不同的人生追求。     

Generating synthetic data to produce public-use microdata for small geographic areas based on complex sample survey data with application to the National Health Interview Survey

Small area statistics obtained from sample survey data provide a critical source of information used to study health, economic, and sociological trends. However, most large-scale sample surveys are not designed for the purpose of producing small area statistics. Moreover, data disseminators are prevented from releasing public-use microdata for small geographic areas for disclosure reasons; thus, limiting the utility of the data they collect. This research evaluates a synthetic data method, intended for data disseminators, for releasing public-use microdata for small geographic areas based on complex sample survey data. The method replaces all observed survey values with synthetic (or imputed) values generated from a hierarchical Bayesian model that explicitly accounts for complex sample design features, including stratification, clustering, and sampling weights. The method is applied to restricted microdata from the National Health Interview Survey and synthetic data are generated for both sampled and non-sampled small areas. The analytic validity of the resulting small area inferences is assessed by direct comparison with the actual data, a simulation study, and a cross-validation study.     

Generating inclusive services for children,youth and families: A shift to using complex systems theory

Service systems for children and families have been shaped by standard approaches to knowledge-building, which reflect a reductionist approach and assume linearity and/or that individuals and experiences are normally distributed. Yet, these approaches may be inadequate for clients most at-risk, especially those who would be analytic ‘outliers’. A complexity lens focuses on the whole system and seeks to identify patterns, including the dynamic interactions between components of the system. Social work scholars have begun to apply complexity theory to social work research efforts, demonstrating the conceptual potential of incorporating this theoretical approach into social work theories and models such as the person-in-environment framework and the ecosystems perspective. Yet, frameworks informed by complexity theory may require ontological and epistemological shifts in thinking and new methodological approaches in order to fully embody a complexity approach. Complexity theory offers the opportunity to consider social work clients who are most at-risk, as it is better suited for power law distributions. We can, therefore, reconceptualize the most ‘at-risk’ clients as being in a state of transition, which is also the space of most creativity and possibility.     

See no evil,hear no evil,speak no evil: assessing complex trauma in young children

Complex trauma generally refers to a child's exposure to multiple traumatic events often within the context of an interpersonal relationship. Childhood traumatic events are commonplace and can have significant implications for physical and mental health. However, traumatic events are often not assessed by clinicians involved in their care. This paper outlines an approach to assessing complex trauma in young children in clinical settings. This approach involves an initial interview, an assessment of traumatic events and trauma symptoms in the child, an assessment of the parent–child interaction, an understanding of the child's functioning in multiple settings, and an assessment of parental trauma where relevant. Complex trauma takes time to assess and is dependent on the parent's ability to recognise and acknowledge the effect trauma has had. The paper concludes with some of the challenges when assessing complex trauma in young children in clinical settings.
