基于技术经济范式的黄河流域农业文明演进

找出推动文明演进的内在核心要素是大力推进新时期生态文明建设的关键。本文从技术经济范式变革的视角构建了一个“技术—组织—环境”的分析框架,探讨了黄河流域农业文明的演进过程与内在机理。研究表明：①农业技术经济范式的变革是农业文明演进的根本动力,它包括以人为主体的农业通用技术的革命,生产组织方式的变化以及农业地理环境的变迁;②黄河流域农业文明的演进呈现明显的阶段性,可划分为新石器时代木石锄耕农业文明、青铜时代金属器锄耕农业文明、铁器时代精耕细作农业文明、机器时代工业化农业文明和计算机时代信息生态农业文明五个阶段;③农业文明的演进呈螺旋式上升,其形态的演变是农业技术经济范式三组分及其带来的生产力和生产关系之间协同创新和协同演化的结果;④促进技术经济范式的绿色化转型是生态文明建设的关键内核。建设以绿色信息技术为核心的资源节约、环境友好的信息生态农业文明将是未来农业文明的发展方向。

Bullying,depressive symptoms and suicidal thoughts

Bullies, victims and pupils neutral to bullyingwere compared on depressive symptoms and suicidal thoughts.The sample included 2,088 Norwegian boys and girls in grade 8. The results revealed that both bullies and victims had significantly higher mean scores than neutral pupils on both depressive symptoms and suicidal thoughts. Victims had a significantly higher mean score on depressive thoughts than the bullies. On suicidal thoughts, the mean score for bullies was above that of the victims, but this differencewas not significant. Girls had significantly higher mean scores than boys on both depressive symptoms and suicidal thoughts. This was the case for all pupils, and for victims, bullies and the neutral pupils. Questions of causality between depressive symptoms, suicidal thoughts and involvement in bullying are discussed and research on this issue is suggested.     

Professional Cultures in Schools With High and Low Rates of Bullying

Most research on bullying in schools has focussed on characteristics of bullies or victims, and their families. Relatively little has investigated the school's contribution to pupil bullying. Information was obtained from teachers in 22 Norwegian primary schools on bullying and 3 aspects of professional culture. The school highest in bullying had significantly worse scores on all professional culture variables than the school lowest on bullying. The results are discussed with reference to the possibility that improvement in professional culture may contribute to less bullying and overall improvement in behaviour. In turn, these may be prerequisites for improvement in academic standards.     

Quality Assurance Issues in European Distance Education

Four major issues concerning quality in European distance education are addressed. (1) The lack of flexibility in educational institutions is a threat to the quality of the present education system. (2) New technologies offer new potential, but also confront us with a need for quality assessment and assurance. (3) New markets in industry and in new regions of Europe highlight the need for quality standards and guidelines. (4) Finally, public assessment and control of quality are under continuous discussion. In general, quality assurance should be approached in various ways and with different measures at institutional, national and international levels.     

Dialogue conferences and empowerment: transforming primary education in Tanzania through cooperation

In this article we present and discuss experiences developed through a dialogue conference which we organised as part of a three-year participatory action research project related to primary education and agricultural education in Tanzania. We explore how dialogue conference as a research method can fill a gap between traditional ways of mutual problem-solving in Tanzania and research. Talking and sharing ideas is important for problem-solving, but the research demonstrated the need for a concrete base for the dialogue. After direct exposition to the local school practice, participants became more responsible and responsive to their environment. The participants agreed upon an action plan and distributed the responsibilities to implement the plan between themselves. The results show that the method opened up for uniting cooperative learning and research among participants and enabled the democratisation of knowledge creation and sharing. We argue that taking cultural conditions and concretisation of local challenges into consideration is important for harnessing the potential of the method in community development-oriented research.     

The Family–School Linkage in Addressing Bullying in Hong Kong: A Sociocultural Perspective

Abstract

The phenomenon that around ten percent of schoolchildren are bullied regularly in Hong Kong has attracted much scholarly attention in anti-bullying research. Current literature suggests taking into consideration the contextual features and socioeconomic factors in anti-bullying research, instead of applying identical intervention/prevention measures across cultures. Therefore, this article examines the role of school-family linkage as a mirror of the wide social-culture context, and analyzes the functions of such linkage in anti-bullying practice in Hong Kong. This study was conducted following a film approach in 2015. That is, a group of middle school teachers in Hong Kong were invited to watch small films showing typical bullying and anti-bullying episodes, followed by semi-structured interviews. The article demonstrates a list of good practices representing the functioning of a positive family-school linkage in bullying addressing. However, parental involvement does not always facilitate and can hinder bullying addressing on campuses. This study implies that efficient bullying addressing aligns with parental involvement in the intervention process, suggesting more parental involvement and more collaboration between family and school in anti-bullying. It also raises an urgent question in regards to balancing the various opinions between parents and teachers in child-raising and bullying addressing. This article suggests further and more investigations examining anti-bullying from a socioeconomic perspective.     

Schoolyard corner society: relating membership to reactive and proactive aggressiveness

This study investigated whether secondary schools in Norway had deviant subcultures, which could be labelled ‘schoolyard corner society’, and how gender and age were related to membership. We also studied levels of reactive and proactive aggressiveness in students, and the relationship between these types of aggressiveness and participation in schoolyard corner societies. Self-reported data were collected from a large, nationally representative sample of Norwegian eighth, ninth and tenth graders (n?=?3342, 1147 boys and 1256 girls). Findings showed that participation in schoolyard corner societies was significantly associated with age, indicating an increasing tendency over time. Reactive aggressiveness as well as power-related and affiliation-related proactive aggressiveness predicted participation to a substantial degree. We also found an interaction between age and affiliation-related proactive aggressiveness in their effects on participation in schoolyard corner societies, which indicates a slight decrease in the effect of proactive aggression over time.
