哲学如何教化

哲学陷入困境的原因在于我们以非哲学的方式教授哲学,哲学有自己的特点,哲学的特点就是沉思和分析。哲学本身是一种本体的或形而上学的思;哲学是一种面向前提的思;哲学是一种面向生活世界的思。哲学应体现出对智慧的追求,对人的价值、意义的思考,以及对时代的关注,应引导学生学习哲学的思维方式,进入哲学活动的世界。

Asymptotic bias in the linear mixed effects model under non-ignorable missing data mechanisms

Summary.  In longitudinal studies, missingness of data is often an unavoidable problem. Estimators from the linear mixed effects model assume that missing data are missing at random. However, estimators are biased when this assumption is not met. In the paper, theoretical results for the asymptotic bias are established under non-ignorable drop-out, drop-in and other missing data patterns. The asymptotic bias is large when the drop-out subjects have only one or no observation, especially for slope-related parameters of the linear mixed effects model. In the drop-in case, intercept-related parameter estimators show substantial asymptotic bias when subjects enter late in the study. Eight other missing data patterns are considered and these produce asymptotic biases of a variety of magnitudes.

Influence diagnostics and outlier tests for semiparametric mixed models

Summary. Semiparametric mixed models are useful in biometric and econometric applications, especially for longitudinal data. Maximum penalized likelihood estimators (MPLEs) have been shown to work well by Zhang and co-workers for both linear coefficients and nonparametric functions. This paper considers the role of influence diagnostics in the MPLE by extending the case deletion and subject deletion analysis of linear models to accommodate the inclusion of a nonparametric component. We focus on influence measures for the fixed effects and provide formulae that are analogous to those for simpler models and readily computable with the MPLE algorithm. We also establish an equivalence between the case or subject deletion model and a mean shift outlier model from which we derive tests for outliers. The influence diagnostics proposed are illustrated through a longitudinal hormone study on progesterone and a simulated example.     

Narrating Significant Experience: Reflective Accounts and the Production of (Self) Knowledge

Notwithstanding the rise of evidence-based practice, other tendencieswithin social work scholarship are also discernible. One ofthese is the study of the everyday, routine accomplishment ofpractice, drawing on microsociological methods and techniques.In this article, I apply techniques drawn from narrative anddiscourse analysis to the study of reflective practice accounts,which hold an important place in social work education. In particular,it is relevant to examine the form that reflective accountstake and the rhetorical and narrative devices deployed withinthem to accomplish a competent professional identity. My argumentis not that such accounts of practice are untruthful, ratherI propose that we would do well to move beyond taking texts(and talk) for granted and treating language as merely the mediumfor expressing inner thoughts and feelings. Social work shouldtake seriously the need to explore its modes of representationand to cultivate a more self-conscious approach to the way professionaland client identities are produced in practice.
