学生在学习语文的时候,总觉得比起其他学科来,语文要“虚”得多。这“虚”的意思就是说语文的知识点不如其他学科那么实在,一堂课下来,有种说不出什么的感觉。的确,语文跟其他学科不一样。有的学科一节课上完,板书上的内容就是本节课的要点,而语文要做到这一点是很不容易的__因为它毕竟比其他学科显得形象化一些、美一些,如果也像有的学科那样利用板书在黑板上以纯文字的形式罗列知识点的话,语文便变得非常枯燥了,学生也不容易理解和感悟。怎样能让学生既明确一篇文章的特色、又不至于割裂文章、影响语文的美感呢?我们想到了形…  相似文献

本研究基于家庭系统的视角采用家庭亲密度和适应性量表中文版(FACESⅡ-CV)对农村留守儿童的家庭功能状况进行调查分析.并与非留守儿童进行了比较。结果发现:农村留守儿童大多数都属于平衡型家庭.其次是中间型家庭.而极端型家庭只占较小的比例;农村留守儿童的家庭功能随着被留守时间的长短而变化。儿童被留守的时间越长,家庭功能得分趋于下降;6岁以前就被留守的农村儿童,其家庭亲密度较低;无论是家庭亲密度还是适应性,留守儿童都要显著低于非留守儿童。家庭经济状况和年龄、性别等人口学变量对农村留守儿童家庭功能没有显著的影响。这表明家庭成员之间的分离或共处时间和空间的减少.都会妨碍家庭成员相互间的情感关系和家庭系统的应对能力。鉴于此.笔者认为在家庭成员之间的分离不可避免的情况下。家庭成员就应该彼此多联系.在情感上相互支持,从而有针对性地弥补留守儿童家庭结构的变化所带来的家庭功能不足。  相似文献

美国于2003年发动的伊拉克战争对中东地区政治制度产生了深刻影响,一些中东国家或政权的政治结构和政治力量对比因此出现了重大变化。其中,尤以伊拉克、黎巴嫩、巴勒斯坦的变化最为显著,它们按照政党制、议会制、选举制的模式各自进行了政治制度变革的尝试,并取得了一定进展,但总体尚不成熟。从西方引进的民主制度无疑改变了这些国家或政权的政治生活,有一定的积极作用,但不是治本良药,中东地区的问题需依靠地区自身来解决。  相似文献

ABSTRACT

The present study examined the influence of acculturation level and family relationships (i.e., positive family support and negative family strain) on quality of life (QOL), using the data from the Population Study of ChINese Elderly (PINE) in Chicago (= 3159). Controlling for sociodemographic variables and health status, it was found that individuals’ acculturation level and positive family support were positively related to QOL, whereas negative family strain was negatively associated with QOL. More importantly, higher acculturation levels were associated with increased protective effects of positive family support and reduced risk effects of negative family strain on QOL among U.S. Chinese older adults.  相似文献

The term “biodiversity” is often used to describe phenomena of nature, which can be studied without a reference to the socially constructed, evaluative, or indeed normative contexts. In our paper, we challenge this conception by focusing particularly on methodological aspects of biodiversity research. We thereby engage with the idea of interdisciplinary biodiversity research as a scientific approach directed at the recognition and management of contemporary society in its ecological embedding. By doing this, we explore how research on and assessments of biodiversity can be enhanced if meaning, aspiration, desires, and related aspects of agency are methodically taken into account. In six sections, we substantiate our claim that the discourse on biodiversity (including the IPBES (Intergovernmental science-policy Platform on Biodiversity and Ecosystem Services) debate) is incomplete without contributions from the social sciences and humanities. In the introduction, a brief overview of biodiversity’s conceptual history is provided showing that “biodiversity” is a lexical invention intended to create a strong political momentum. However, that does not impede its usability as a research concept. Section 2 examines the origins of the Convention on Biological Diversity (CBD) by way of sociological discourse analysis. Subsequently, it proposes a matrix as a means to structure the ambiguities and tensions inherent in the CBD. The matrix reemphasizes our main thesis regarding the need to bring social and ethical expertise to the biodiversity discourse. In Section 3, we offer a brief sketch of the different methods of the natural and social sciences as well as ethics. This lays the groundwork for our Section 4, which explains and illustrates what social sciences and ethics can contribute to biodiversity research. Section 5 turns from research to politics and argues that biodiversity governance necessitates deliberative discourses in which participation of lay people plays an important role. Section 6 provides our conclusions.  相似文献

Guided by Cantor’s social care model, this study identified individual, family, and social support factors that influence urban older adults’ need for home- and community-based services, including medical and rehabilitation, instrumental care and support, and psychosocial services. The data were extracted from the Sample Survey on Aged Population in Urban/Rural China conducted by the China Research Center on Aging in 2006. Results from multiple logistic regression show that older adults’ need for medical and rehabilitation services is significantly related to instrumental activities of daily living, depression, not having filial children, friend support networks, and having a confidant. Older adults’ need for instrumental care and support is related to their educational attainment, financial strain, instrumental activities of daily living, not living with children, and friend support networks. Finally, older adults’ need for psychosocial services is significantly related to educational attainment, depression, not being married, friend support networks, and having a confidant. Implications for social service development are discussed.  相似文献

Green spaces in cities provide cultural ecosystems services (CES) such as nature connection, wildlife interaction and aesthetic appreciation which can improve aspects of human well-being. Recognising these benefits, researchers are now examining the complex relationship between humans and nature in urban social-ecology. Most studies investigate people’s appreciation and valuation of different green space features and their contribution to urban biodiversity. Recommendations arising from such studies are best practices to achieve a balance between landscape aesthetic and ecological objectives, but many knowledge gaps still exist. In a social-ecological project in Greater London, appreciation of ponds and dragonflies in urban green spaces, and the environmental factors determining dragonfly diversity were investigated. We found ponds and their appearance were valued by people as enhancing their green space experience. The preference for wild-looking ponds was moderate. Dragonflies were enjoyed for their colour and high visibility, especially by those who had basic dragonfly knowledge. Species richness of dragonflies was positively associated with habitat heterogeneity in and around a pond. However, people were unable to relate a heterogeneous pond to more dragonfly species. For the first time, some factors that influence the human appreciation-ponds-dragonflies (HPD) relationship in an urban context are revealed. To fully realise the CES potential of ponds and dragonflies in Greater London, a HPD framework is proposed. The framework underpins strategies that foster cultural sustainability for ponds and dragonfly conservation.  相似文献

This study explored whether and how family relationships and social connections influence depressive symptoms of older migrants and older adults in transnational families using the data gathered from a cross-sectional survey in Los Angeles, California, United States, and Beijing, China. Regression results showed that the older migrants reported significantly higher levels of depression than the elders in transnational families. The findings highlight the importance of maintaining close family relations and having large friendship networks for older adults in international migrant families.  相似文献
