美的教育与高校思想政治工作

在高校思想政治工作中,美的教育可以起到开发智力、道德感化、人生导向等作用.在思想政治工作中善于运用美的教育,创造美的环境、展现美的人格、追求美的方法,对于增强思想政治工作的吸引力,提高思想政治工作的成效具有积极意义.     

孔子的教育思想探究

《论语》是儒家学派创始人孔子言论的汇编,是儒家的经书。其中体现孔子教育思想方面的一些重要表述,如个性品质教育、坚持的教育准则、倡导的学习方法,经过两千余年教育史的验证,特别是经过现代教育理论的评断和现代教育实验的检验,充分证明是普遍性的教育规律,就是在未来教育中也定会闪烁其奕奕光彩。     

大学数学基础课教学中融入数学建模思想的实践

数学建模不仅限于解决实际问题,也可以是数学发展过程中提出的理论问题。基于近年来在大学数学基础课教学中融入数学建模思想的教学实践,论述了其主要思路与做法。介绍了将数学建模思想融入数学基础课教学的两个教学案例,即微积分方法的本质和从方程组出发引入线性相关与线性无关概念。     

Robust tests for the common principal components model

When dealing with several populations, the common principal components (CPC) model assumes equal principal axes but different variances along them. In this paper, a robust log-likelihood ratio statistic allowing to test the null hypothesis of a CPC model versus no restrictions on the scatter matrices is introduced. The proposal plugs into the classical log-likelihood ratio statistic robust scatter estimators. Using the same idea, a robust log-likelihood ratio and a robust Wald-type statistic for testing proportionality against a CPC model are considered. Their asymptotic distributions under the null hypothesis and their partial influence functions are derived. A small simulation study allows to compare the behavior of the classical and robust tests, under normal and contaminated data.     

Nonparametric control charts based on runs and Wilcoxon-type rank-sum statistics

In this article, we introduce three new distribution-free Shewhart-type control charts that exploit run and Wilcoxon-type rank-sum statistics to detect possible shifts of a monitored process. Exact formulae for the alarm rate, the run length distribution, and the average run length (ARL) are all derived. A key advantage of these charts is that, due to their nonparametric nature, the false alarm rate (FAR) and in-control run length distribution is the same for all continuous process distributions. Tables are provided for the implementation of the charts for some typical FAR values. Furthermore, a numerical study carried out reveals that the new charts are quite flexible and efficient in detecting shifts to Lehmann-type out-of-control situations.

Promoting Fathers' Engagement With Children: Preventive Interventions for Low‐Income Families

Few programs to enhance fathers' engagement with children have been systematically evaluated, especially for low‐income minority populations. In this study, 289 couples from primarily low‐income Mexican American and European American families were randomly assigned to one of three conditions and followed for 18 months: 16‐week groups for fathers, 16‐week groups for couples, or a 1‐time informational meeting. Compared with families in the low‐dose comparison condition, intervention families showed positive effects on fathers' engagement with their children, couple relationship quality, and children's problem behaviors. Participants in couples' groups showed more consistent, longer term positive effects than those in fathers‐only groups. Intervention effects were similar across family structures, income levels, and ethnicities. Implications of the results for current family policy debates are discussed.     

“Which One Is Yours?”: Children and Ethnography

This paper explores roles that children play in ethnographic research. Based on the limited literature on children in the field, and drawing on examples from ethnographies across disciplines, I identify four roles for children: 1) as “wedges,” or as instrumentally important in helping adult ethnographers gain access in various ways; 2) as collaborators; 3) as objects of study; and 4) as subjects of study. I also discuss the ways in which these roles illuminate key methodological issues in ethnography, like reflexivity, ethics, and agency. The paper synthesizes and integrates previously disconnected research on the presence of children in the field with ethnographies in which children and childhood are the topics of research. I draw on my own fieldwork experiences for further illustration.

Students’ health engagement and affective relations in Danish upper secondary school

To increase our understanding of the dynamics of young people’s embodied engagement in health, this article analyses Danish upper secondary school students’ understandings and practices of health and the role of the school environment in these dynamics. Participatory, visual and narrative data were collected during fieldwork with 37 students aged 16–17. Deleuze and Guattari’s philosophy of the body is applied to analyse the affective relations and emerging body-health assemblages within the students’ school life, which generated force and vitality (here conceptualised as health). Through becoming within sensuous, social and political body-health assemblages, the students attempted to curb school stress, sustain social belonging in an individualistic school environment and both reproduce affirming power discourses and subvert their territorialisation. The study proposes an analytical shift in perspective on young people’s health away from an individualistic ‘components approach’ towards a relational understanding, and suggests that students’ health at school relates to collectivity, quality, rhythm and co-produced engagement, rather than individuality, quantity, rules and performance, which increasingly characterise Danish health discourse and school policy.     

Observational sketching as method

This paper explores the potential of observational sketching as a social science research tool, informed by our own recent experiments with observational sketching techniques and approaches. We first outline the historical roots of academic sketching and note a recent resurgence of interest in sketching in certain disciplines. We then introduce our own explorations in sketching as method, based on a year-long collaboration between an observational artist and a group of qualitative researchers with interests in creative methods. The paper outlines some of the lessons we learnt from our partnership, focusing on three themes: (i) ‘sketchiness’; (ii) ‘concentrated seeing’ and (iii) sketching as interaction. We conclude that observational sketching generates a refreshingly different form of visual data which has considerable potential to be used as a complement to other methods, including as a participatory method and as a useful tool for thinking.
