能源安全战略的实施顺序   总被引：4，自引：1，他引：4  

邹艳芬  魏晓平 《资源科学》2005,27(5):55-61

能源是现代社会必不可少的投入,就如人体的血液一样,保障能源安全能够促进经济社会的发展.但能源安全战略实施需要投入的资金巨大,在我国现有的经济、财政条件下,不可能也没有必要同时实施所有战略,因此,必须按照一定的顺序,主次分明地对战略进行有序地实施.本文通过分析能源安全的经济作用,并运用社会福利准则分析能源安全的社会作用,说明能源安全对经济、社会等的作用是有限度的,相对于能源不安全对社会和国家造成危害的无法估量性,决定了国家的能源安全战略实施顺序的选择,不应该以传统的效益可得性为依据,而应该在充分考虑全球能源状况和国家经济及能源供需等具体条件下,按照能源的危机程度及先短期后长期等原则排列.最后,依据中国的具体情况,提出了中国能源安全战略的实施顺序.  相似文献

Turning in or tuning out? Listening to silences in education for critical political consciousness     

Leah S. Stauber 《International journal of qualitative studies in education》2017,30(6):560-575

What happens when a team of university education researchers initiates a social justice learning project in a local high school, and – despite the overall project’s considerable successes in cultivating students’ critical political ‘voice’ – is confounded by the periodic, apparent ‘silences’ of some of its young female students? Drawing on eight years of fieldwork in a groundbreaking high school social justice education classroom, this article examines the presumptions inherent in certain forms of social justice pedagogy, and the ways in which ensuing classroom disjunctures may, in fact, lead to deeper insights about education for youth critical social consciousness. The article focuses on two, interrelated issues: the unsettling and sometimes confounding ‘silences’ of female students and the correlation between such silences and social justice educators’ attenuated ability to recognize and support the myriad ways in which minority female students may encounter, negotiate, and articulate their own particular forms of Freirian conscientización.  相似文献   

Associations between motor proficiency in children with history of maltreatment and living in social economically vulnerability     

《Child abuse & neglect》2017

Maltreatment and living in poor socioeconomic conditions during childhood may implicate in deficits on motor proficiency, nevertheless, the literature on this issue is still scarce. The goal of the study was to investigate the possible associations among manual dexterity, aiming and catching tasks, and balance tasks for children who suffers maltreatment and lived in social vulnerability. Eighty-two (82) children (08-09 years old) participated in the study. Forty-one (41) belong to the (SEV-M Group) children living in social economic vulnerability and were previously maltreated (lived in foster homes as results of parental neglect and domestic violence), and 41 belong to the (SEV Group) children living in social economical vulnerability with no history of childhood maltreatment. Children were assessed using the Movement Assessment Battery for Children –2nd Edition. Structural Equation Modeling was used to analyze the data. The results suggest the existence of a variety of motor difficulties in the group of children who suffered from neglect and domestic violence. The statistics model showed a negative effect for children in at-risk environments (regression coefficient = −0.30) and only showed a significant effect (p = 0.04) for balance abilities. Traumatic experiences may have a negative effect on children’ balance proficiency.  相似文献   

Clout or doubt? Perspectives on an infant mental health service for young children placed in foster care due to abuse and neglect     

《Child abuse & neglect》2017

Despite knowledge about the profound effects of child abuse and neglect, we know little about how best to assess whether maltreated children should return home. The effectiveness of the New Orleans Intervention Model (NIM) is being tested in a randomized controlled trial where the comparison is social work ‘services as usual.’ The future trial results will tell us which approach produces the best outcomes for children; meanwhile qualitative process evaluation is generating intriguing findings about the perceived impact of NIM on decision-making about childrens’ futures. Interviews and focus groups were conducted with social workers, foster carers, legal decision-makers and the NIM team (n = 63). Data were analysed thematically. Findings suggest that NIM is seen as bringing greater influence (‘clout’) to decision-making due to its depth of focus, provision of treatment for the family, health professional input and perceived objectivity. Simultaneously, the NIM approach and the detailed information it produces potentially throws judgments into doubt in the legal system. Clout/doubt perceptions permeate opinions about NIM and are inter-related with a historical discourse about ‘health versus social’ models of information gathering, with implications for assessment of child abuse and neglect that extend beyond the study context. The juxtaposition of ‘clout versus doubt’ both highlights and is strengthened by an intense focus among social workers and legal professionals on how evidence will be regarded within legal fora when making decisions about children. There is continuing uncertainty in the child welfare system about the best ways of assessing maltreated children, underscoring a continued need for the trial.  相似文献

中国教育人类学传统图景的构建与评论     

巴战龙 《当代教育与文化》2020,(1):17-20,46

中国教育人类学是中国人类学学科群中活动最频繁、发展最迅速的分支学科之一,但是长期以来它被看成是改革开放以来的产物,认为其学科史极其短暂,可以叙述但无须研究。陈学金的《中国教育人类学简史》挑战了上述传统观点,不仅开展了较为深入和系统的"中国教育人类学的历史研究",而且提出和论说了若从1905年王国维提出"教育的人类学"的术语和内涵算起,教育人类学在中国已有上百年学科史的新锐观点。从历史和现实相交织的视角出发清晰和准确地界定何谓教育人类学,是分析和论述教育人类学存在与发展的合法性的基本前提,因而在未来的教育人类学的发展进程中,这本学科史的先驱性著作是"绕不开的研究",必将占有重要的学术地位。  相似文献
