‘Youth is Present Only When Its Presence is a Problem’: Voices of Young People on Discipline in School

Discipline in schools is a topic of enduring public interest and concern. This article reviews findings from three recent research studies, which gathered views of young people on this issue in mainstream, alternative and special school settings. It reveals the confusion and frustration of students seeking to contribute to the debate, often on aspects that affect them directly and significantly. Their reflections are contextualised within a discussion of different conceptualisations of discipline, and from there, it is argued that, by strengthening the voice, power and presence of young people in dialogue on this key issue, the debate itself will be more relevant and well‐focused.     

Parameter identification for the discretely observed geometric fractional Brownian motion

This paper deals with the problem of estimating all the unknown parameters of geometric fractional Brownian processes from discrete observations. The estimation procedure is built upon the marriage of the quadratic variation and the maximum likelihood approach. The asymptotic properties of the estimators are provided. Moveover, we compare our derived method with the approach proposed by Misiran et al. [Fractional Black-Scholes models: complete MLE with application to fractional option pricing. In International conference on optimization and control; Guiyang, China; 2010. p. 573–586.], namely the complete maximum likelihood estimation. Simulation studies confirm theoretical findings and illustrate that our methodology is efficient and reliable. To show how to apply our approach in realistic contexts, an empirical study of Chinese financial market is also presented.

透析生活史研究在古德森教师研究中的角色

生活史研究已日渐运用于当代教育研究中。英国教育社会学家艾沃·古德森不仅较早地将其用于课程研究，还更多地用于教师研究。文章考察了古德森不同阶段的教师研究，分析了生活史研究在教师研究中所扮演的角色：为教师生活研究提供研究方法；为在"中间地带"建构理论提供资源；为促成教师"叙事学习"和"叙事教学"场域奠定基础。指出运用生活史研究是古德森教师研究生涯中一以贯之的思想，背后有其对教师深刻的社会关怀。这一思想在其教师研究中扮演着多重角色，对我国教师和教师教育研究者及实践者而言，有诸多借鉴意义。     

Giving time or giving money? On the relationship between charitable contributions

This paper studies philanthropic behaviour in terms of money and time contributions for charitable organisations. Using a unique dataset, which is representative of the German population, we examine the pure contributions of individuals who give either money or time as well as joint contributions of individuals who give both money and time. We find that the sequential decisions to give to charity and how much to give can be explained by different socio-economic characteristics. We report particularly pronounced gender differences among pure contributions, an interesting pattern of human capital variables such as income and education, and possible differences in the type of philanthropic goods.     

学前教育师范生TPACK现状调查及教学改革建议

在“互联网+”及多元文化知识不断融合的教育背景下，信息技术在教学中被提升到一个新的高度。为了解学前教育师范生群体对信息技术知识在教学活动中的应用程度，笔者采用自编的《学前教育师范生TPACK》量表对220名在校学前教育师范生进行调查。统计分析发现：1）学前教育师范生的总体TPACK知识掌握较好，但技术知识仍然较为薄弱；2）学前教育师范生TPACK知识存在显著的年级差异，但性别差异不显著；3）信息技术爱好和训练会造成学前教育师范生TPACK知识的差异。应采取的对策：1）注重培养学前教育师范生的信息技术知识和能力；2）大力推进第二课堂，促进TPK和TCK的发展；3）进行产学研合作，提升学前教育师范生的TPACK水平。     

Early Childhood Education Centre Director Perceptions of Challenging Behaviour: Promising Practices and Implications for Professional Development

Given their key role in overall programme quality, it is critical to examine how early childhood programme centre directors in the United States perceive challenging behaviour. Participants completed a survey asking which behaviours they perceive to be most problematic, the number of children dismissed or expelled from the programme during the last year, and the most commonly used strategies for addressing challenging behaviours. Results point to several promising practices and highlight the variability in access to evidence‐based practices based on programme type. Areas that warrant more targeted professional development are discussed, and findings are situated within the larger early childhood context.     

Allocation of resources in asymmetric competitions: How do the weak maintain a chance of winning?

To maintain a chance of occasionally beating a stronger player in a competition waged over several fields, a weaker player should give up on some of the fields and concentrate resources on the remaining ones. But when do weak players actually do this? And which fields do they give up when the fields differ in their likelihood of being assessed? We report an experimental study of resource allocation in which asymmetric pairs of players compete over asymmetric fields. Symmetric players and symmetric fields are used for control. We find that players behave as follows: (1) Average wins are the same in the symmetric and asymmetric fields conditions and correspond to relative player strength. (2) The proportion of fields given up on decreases with a player’s greater relative strength, increases for asymmetric field likelihoods, and increases when competitions are framed in meaningful context; this proportion is related to wins. (3) When field likelihoods are asymmetric, players’ resource allocation is correlated with likelihood. Wins generally increase with that correlation but the relation is different for players of different strength. (4) The proportion of fields given up on and the correlation with likelihood change with experience towards the values corresponding to higher wins.
