北京山区生态农业的功能定位、模式与评价指标体系

北京山区生态农业包括三项基本功能,这就是水资源与环境功能、经济功能和社会文化功能。北京山区在长期的生产实践中,逐步形成了两种类型的生态农业模式:一种是农户生态园式的生态农业模式;另一种是产业化经营式的生态农业模式。北京山区生态农业的评价应从系统结构、系统功能、系统效益三个方面进行整体评价。通过系统评价,择优选择系统结构合理、系统功能较强、系统效益良好的生态农业模式。     

以传统"艺术心性论"会解西方美学--1949年以前中国学者接受西方美学影响的一个结构性倾向

本文把中国美学对西方美学的接受作为一典型的阐释学境域.在此境域中,中国学者对西方美学的接受与阐释显示出了一种普遍的结构性倾向,即用老庄一脉思想所模塑的传统"艺术心性论"来会解西方近代以来的美学,此"艺术心性论"隐蔽地发挥着融合中西--形成新的美学知识范式的结构性作用.由此剖析了王国维、宗白华、朱光潜三大家美学思想中未明言的艺术层面和由此产生的对西方美学的"误解".     

基于优势的学习困境学生社会工作干预策略初探——以北京市DC区HZ中学某个案为例

优势视角是于20世纪八、九十年代在西方社会工作领域兴起的一种实践工作取向。它注重案主的优势与潜能,挖掘案主所处环境中的资源,提倡合作、陪伴的互动关系,坚持发展与成长的服务方向。目前,这一工作手法已被运用于多种人群中,学习困境学生是教育、心理、社会工作等领域始终关注的重要群体。在本文里,笔者阐述了该理论的基本假设和主要概念,介绍了研究的方法、对象和相关设计,提出通过"3I"——I have、I am、I can的策略来实施干预,最后对整个介入过程进行了反思和总结。     

Conceptualizing community in the context of work and family

In recent years, many work-family scholars and practitioners have called for expanding the analysis of work and family to include community. This paper uses the ecological systems approach as a framework for selecting and reviewing community concepts thought to be relevant to the analysis of work, community, and family. Based on the work-family literature and the review of community concepts, the paper creates a set of common categories of characteristics for the analysis of relationships among community, work, and family. The development of such categories is a first step in understanding work, community, and family as interrelated domains. Hopefully, they will be useful for developing and testing hypotheses regarding interrelationships among work, community, and family and the effects of work, community, and family characteristics on domain quality and individual well-being. On a vu, au cours de ces dernières années, de nombreux professeurs et praticiens demander que soit étendue l'analyse du travail et de la famille pour inclure la communauté. Cet article utilise l'approche des systèmes écologiques comme base de sélection et d'étude des principes de communauté considérés pertinents dans l'analyse du travail, de la communauté et de la famille. Ensuite, en s'appuyant sur la littérature visant le travail et la famille, ainsi que sur l'étude des principes de communauté, l'article établit un jeu de catégories communes des caractéristiques permettant l'analyse de rapports entre communauté, travail et famille. L'établissement de telles catégories constitue un premier pas envers une meilleure compréhension de l'interrelation entre les domaines du travail, de la communauté et de la famille. Il est à espérer que cela sera utile envers le développement et l'évaluation des hypothèses visant à établir une relation entre le travail, la communauté et la famille, ainsi que l'influence qu'auraient les caractéristiques du travail, de la communauté et de la famille sur la qualité du domaine et la qualité de la vie.     

Global standards for social work education and training

This paper explores the ways in which social workers can be helped to acquire the wider understanding of relevant legal frameworks which is currently necessary for child-centred practice, given the influence of an ecological perspective on such practice. It arises from the development of a module on child care social work and the community for the Post Qualifying Child Care Award by members of the Law and Social Work Departments at Brunel University. The authors believe that to reach beyond a tokenistic acknowledgement of the ecological perspective requires an understanding and experience of the complex layers which make up the widening and complex social worlds of the child. The paper explains how social workers were encouraged to appreciate both the ever-widening circles of potentially relevant law and the different roles through which law operates. It concludes that a deeper engagement with the legal implications of an ecological dimension to practice would make such practice more effective and would also help combat social exclusion and discrimination.

Crucial factors determining the spatio-temporal distribution patterns of threeAthalia sawflies feeding on common cruciferous plants

Summary ThreeAthalia sawflies,A. japonica, A. rosae andA. infumata, feeding on cruciferous plants, coexist in Japan. However, it is not known what ecological strategies they use and what environmental factors are crucial to such strategies. I attempted to explain these questions by examining the relationship between the spatio-temporal distribution patterns of threeAthalia sawflies and their habitats in three districts (Lowland, Intermediate and Mountain). The three sawflies have different spatio-temporal distribution patterns, though they usually used common cruciferous plants.A. japonica was abundant in spring and autumn but disappeared during summer in all the districts. In the Lowland, populations ofA. rosae andA. infumata, like that ofA. japonica, crashed in summer. HoweverA. rosae occurred mainly in summer in the Intermediate and Mountain. AlthoughA. infumata occurred in the same seasons asA. rosae in all districts, population levels ofA. infumata were always lower than those ofA. rosae. The crucial factors controlling their population patterns were the availability of host plants and temperature. Population crashes ofA. rosae andA. infumata were due to food depletion, and those ofA. japonica were due to heat stress. On the other hand, their population patterns may be interpreted as phenological synchronization with their original host plants, though they all existed on common cruciferous plants. The three sawflies may have evolved different strategies to escape from unfavorable habitat conditions. Such strategies are speculated to be summer diapause inA. japonica, long distance migration inA. rosae, and local dispersal inA. infumata.

论网络时代中国新闻传播业的生态变迁

网络媒体的物质特性、传播特性决定了网络媒体产生后的中国新闻传播业必然发生深刻的生态变迁 ,传统新闻传播学话语被改写甚至被置换。这主要体现在新闻传播者主体席位增加与“受众”的消解 ,“线性模式”崩溃与“控制研究”式微 ,新闻传播媒体自身形态和外部环境的变化等。
