Interval estimation in discriminant analysis for large dimension

This paper is concerned with the interval estimation for the log odds of the posterior probability that the observation vector belongs to one of two homoscedastic multivariate normal distributions (Π₁ and Π₂). We give the limiting distribution of the unbiased estimator for the log odds as the sample sizes and the dimension jointly tend to infinity, and approximate the confidence interval based on the asymptotic distribution. Small-scale simulations are performed to check the precision of the approximation.     

From advocacy to service provision: state transformation and the disability rights movement in Taiwan

This research uses the development of the disability rights movement in Taiwan as a case study to analyze the impact of state transformation, in particular marketization of social welfare policy, on the disability rights movement. First, the institutionalization of the disability rights movement enabled it to expand its organizational structure and become involved in shaping policy. Secondly, when disability rights organizations started to undertake state-funded projects, their focus shifted from advocacy to service provision. Thirdly, competition for limited state-funding gave the organizations led by urban-middle class advocates a significant advantage over small, community-based NPOs and gathered significantly greater resources. Finally, this paper suggests that, in a context in which the state did not provide basic social services for its citizens with disabilities, the institutionalization of SMOs turned advocacy groups into service providers. Although the number of disability civic organizations increased, the voices of advocacy groups were weakened.     

Who is a Distracted Driver? Associations between Mobile Phone Use while Driving,Domain‐Specific Risk Taking,and Personality

Mobile phone use while driving (MPUWD) is an increasingly common form of distracted driving. Given its widespread prevalence, it is important for researchers to identify factors that may predict who is more likely to engage in this risky behavior. The current study investigates associations between MPUWD risk behaviors, domain‐specific risk perceptions, and broad personality dimensions. An Italian community sample (n = 804) completed a survey regarding MPUWD risk perceptions and engagement in MPUWD, in addition to the HEXACO‐PI‐R, a broad six‐factor personality inventory (honesty‐humility, emotionality, extraversion, agreeableness, conscientiousness, openness to experience), and the DOSPERT, a six‐factor domain‐specific self‐report risk‐taking measure (health/safety, recreational, social, ethical, gambling, and investment). With respect to domain‐specific risk taking, greater frequency of SMS use while driving most strongly was associated with greater risk taking for the health/safety, gambling, and ethical risk domains. Further, greater honesty‐humility and conscientiousness, two traits related to cognitive control and risk behaviors, and to a lesser extent openness to experience, were associated with less frequent MPUWD, and positively associated with MPUWD risk perceptions. With growing public safety concern surrounding MPUWD, understanding associated personality factors is not only important for identifying psychological mechanisms underlying risk behavior, but also for more effective prevention and intervention programs.     

Teaching Black History after Obama

This article is a reflection on the teaching of black history after the Obama presidency and at the dawn of the Trump era. It is both an analysis of the state of the academic field and a primer on how to integrate the past few decades of scholarship in black history broadly across standard K-12 curriculum. It demonstrates the importance of theorizing black history as American history rather than just including African American content in US History courses and offers specific methods that can shift the narrative in this direction even within the confines of a more traditional telling of the American past. Finally, it situates the voluminous work of historians of the black past as critical interventions in pedagogy necessary to challenge today's unrelenting attacks on public education.     

论生态环境损害赔偿诉讼与环境公益诉讼之衔接

在现行司法实践中,我国对生态环境损害之救济采取的是生态环境损害赔偿诉讼与环境公益诉讼并行的"双轨制"模式.通过分析典型案件可以发现,现行立法未能为化解生态环境损害赔偿诉讼与环境公益诉讼之间的制度"碰撞"提供明确的规范指南,导致"两诉"之间时常会陷入管辖冲突与衔接困境.生态环境损害赔偿诉讼的模糊属性以及相关立法规定的缺失,是导致"两诉"衔接陷入困境之根由.为此,应当在准确识别生态环境损害赔偿诉讼性质之前提下,通过立法对"两诉"之间的顺位规则、索赔主体机制等核心规范予以明确.具体而言,未来我国应当明确生态环境损害赔偿诉讼优于环境公益诉讼的顺位规则,并建立"行政机关—环保组织—检察机关"三位一体且逐层递进的索赔主体结构,最大程度发挥"两诉"之制度合力.     

Contingent constellations: African urban complexity seen through the workings of a Ghanaian bus station

In this article, I explore the intricate relationship between regulation and contingency in processes of urban economic organisation by focusing on the workings of a central bus station in Accra, Ghana. After introducing the position of the station in Ghana’s urban economy and transport infrastructure, I set out its internal regulative arrangements in relation to larger socio-economic and political constellations the practices of the station workers are contingent upon. Next, I turn the analysis around and describe the ways in which people accommodate themselves within, exploit and thereby co-produce emergent contingencies. The focus on the station, I suggest, offers a window into the complex constituents of niche economic practices that prevail in many spheres of African cities and allows a nuanced reflection on the incongruous and undetermined dynamics of everyday urban ‘becomings.’     

多重人格语境下商人身份与人格关系研究

罗马法上的人格同时规定了人在公法与私法上的主体地位,是一种通用型人格,因此罗马法上的人格是法律主体资格而非权利主体资格。德国法上民事人格采取的是权利能力理论,而商事人格采取的是商人"身份人格理论",即商人既是一种身份,又是商事主体,商人在获得商人身份的同时获得商事人格,成为商事主体。某一主体可以同时获得多重人格"面具",也可以仅仅获得单一人格"面具"。民事人格、商事人格等独立的类型化人格所形成的人格多重性,其缘由在于诸法合一向诸法分立的转变以及社会分工加深了"完整人"向"局部人"的蜕变。现代人格理论的缺陷在于将民法上的"人"当作法律上的"人",试图以"局部人(民法上的人)"替代"完整人(法律上的人)",将类型化人格(民事人格)作为通用型人格使用。     

Is implementation fidelity associated with improved access to care in a School-based Child and Family Team model?

Effective child and family centered service planning is crucial to addressing vulnerable children's needs. However, there is limited evidence about what facets of these processes improve service use and outcomes. The current study used a Poisson random effects hazard model to test correlations between fidelity to NC's Child and Family Support Team model and time to service receipt, using case management data for 3396 children served by that program during the 2008–2009 school year. Students were more likely to receive recommended services more quickly when caregivers and the students attended planning meetings, when their plans included services for caregivers, and when child and family team leaders followed up after meetings to verify service receipt. Contrary to the Child and Family Support Team theory of change, match between student needs and the lead agency of the meeting was not associated with the odds of quicker service receipt, nor was attendance by natural supports. Findings from this study demonstrate the potential effectiveness of using case management systems to measure service planning process fidelity, as well as how results thereof can both inform process improvement and potential refinements to models’ theories of change.
