‘When words don't come easily’: personal narratives from adolescents experiencing shyness as an emotional and behavioural problem in the school context

The purpose of this article is to present narratives from 15 adolescents experiencing shy behaviour as an emotional and behavioural problem in the school context in light of narrative understanding. The investigation is intended to generate knowledge about this largely under‐researched phenomenon based on the personal accounts of those who are actually experiencing it. Their narratives are the foundation for a discussion regarding implications for future practice in the context of school in relation to this group.     

School context and instructional capacity: A comparative study of professional learning communities in rural and urban schools in China

This study examines the teaching gap between rural and urban schools in China from the perspective of teacher professional learning communities (PLCs). Drawing on in-depth interviews with 36 primary school teachers, the study finds striking disparities between rural and urban schools in the working of Teaching and Research Groups (TRGs). These disparities in TRGs result in divergent patterns of instructional capacity building in rural and urban schools. The evidence shows that teaching and teachers are strongly shaped by the school organizational context. It suggests that strengthening school-wide PLCs is an important way of narrowing the rural-urban teaching and learning gaps.

In-house consultation to support professionals’ responses to child abuse and neglect: Determinants of professionals’ use and the association with guideline adherence

This study examined the presence and strengths of determinants associated with consultation of an in-house expert on child abuse and neglect (CAN) by preventive child health care professionals who suspect CAN. This study also assessed the relationship between in-house CAN expert consultation and professionals’ performance of six recommended activities described in a national guideline on preventing CAN for preventive child health care professionals. A total of 154 professionals met the study’s inclusion criteria. They filled in a questionnaire that measured in-house consultation practices and twelve determinants associated with the professional, the in-house expert, and the organizational context. Bivariate and multivariate regression analyses were performed. Almost half of the participants (46.8%) reported to consult the in-house expert in (almost) all of their suspected CAN cases. Professionals who reported better recollection of consulting the in-house expert (i.e. not forgetting to consult the expert) (p = .001), who were more familiar with consultation (p = .002), who had more positive attitudes and beliefs about consultation (p = .011) and who reported being more susceptible to the behavior (p = .001) and expectations/opinions (p = .025) of colleagues regarding in-house expert consultation were more likely to consult the in-house expert. Furthermore, in-house expert consultation was positively associated with two of six key guideline activities: consulting the regional child protection service and monitoring whether support was provided to families. The implications of these results for improving professionals’ responses to CAN are discussed.

中西政治制度设计中的“人性假定”

任何一种制度的安排,都应该建立在特定的人性认识基础之上。中西不同的人性假定,导致了不同的治政方略和制度路径。西方政治制度理念的基本分析框架,是建立在人性恶论基础之上的权力分立和制衡思想,其基本的哲学判断是＂制度高于人性＂;中国传统政治制度理念的基本分析框架,则是建立在人性善论基础之上的崇尚德治与集权专制思想,其基本的哲学判断是＂人性优于制度＂。＂性善＂与＂性恶＂两种不同的人性假定,导致了中西＂德治＂与＂法治＂不同的政治文化与政治制度设计。＂德治＂与＂法治＂分别构成了中西政治哲学的核心理念。儒家文化中的人性本善假定从民族文化精神和心理的角度看,固然提升了人们对民族文化的自尊自豪感、民族自信心以及民族凝聚力,但却对中国政治发展也产生过一些不良影响。中国传统的德治思想必须突破和超越人治的范畴,必须在私人领域和公共领域两相区分的前提下,参照西方的宪政理念与法治经验,方可为当代中国的政治建构提供有益的借鉴。     

从理论宣传角度审视五四时期“问题与主义”之争

20世纪初的＂问题与主义＂之争早已尘埃落定,但它所警告的教条主义空谈理论的危险并没有随之消失。＂问题与主义＂之争中提出的宣传＂主义＂和＂学理＂的方法,对我们今天的理论宣传仍有很大启发。
