京津冀一体化河北省钢铁产业转型升级效果评价指标体系构建及应用研究

在实施产业转型升级过程中,构建合适的效果评价指标体系是一个复杂而重要的环节。依托京津冀一体化的发展现状,在分析了评价指标体系设计原则的基础上,从河北省钢铁产业转型升级对环境的影响、对省内经济的产业贡献和产业自身高效持续发展这三个维度出发,建立了京津冀一体化背景下河北省钢铁产业转型升级效果评价指标体系,为河北省钢铁产业转型升级的效果评价提供了一种结构性方法。据此,又提出了运用这一指标体系具体实施评价的原则与思路,从而为这一宏观实践活动提供了有益的启示。     

傣泰民族起源与傣泰民族文化圈的形成新探

中国古代不存在一个可成其为民族的越人族体,泰人也不是越人演变而来的,傣泰民族在汉代以前的历史的追溯已无意义。傣泰民族可追溯的源流在汉代云南滇中,并随后向南迁移到今天的云南南部及东南亚一带。由于傣泰民族在长期的历史迁移与发展中保持了水稻种植、“勐-阪”制度与文化的复制模式,使傣泰民族的先民们能在长期的迁移过程中定居并壮大起来,从而在今天形成了一个傣泰民族居住的文化圈。傣泰民族文化圈是一个文化地理概念,基于共同的民族渊源关系,人们互相理解、宽容、合作、开展社会与经济的交流,共同促进民族与文化的发展,是当代理解傣泰民族文化的新思维。

莱麦草染色体组分析及染色体变异的观察

通过对有丝分裂中期及减数分裂终变期染色体数目统计,形态、行为的观察,发现莱麦草染色体呈现广泛的变异：有丝分裂中期株内染色体数目在2n＝11──56内变化,含有本物种染色体数目2n＝28的细胞仅占统计数的27．8％。减数分裂终变期出现36％具非整倍性的花粉母细胞,染色体数除数目变异外还有结构变异如Robertson易位等。本文对该种进行了染色体组分析,确认其为同源四倍体。同时对该物种株内产生混倍性的原因,在物种进化上的意义进行了探讨。

Childhood family structure and young adult behaviors

This paper examines a wide variety of forms, and full histories, of family structure to test existing theories of family influences and identify needs for new theories. The focus is on links between childhood family structure and both completed schooling and risk of a nonmarital birth. Using a 27-year span of panel (PSID) data for U.S. children, we find that: (a) change is stressful, (b) timing during childhood is relevant, (c) adults other than parents are important, and (d) two more recently studied family structures (mother-with-grandparent(s) and mother-with-stepfather) do not fit the molds of existing theories. The findings suggest that new theories should consider allocation of resources and reasons people group into family structures. Received: 11 September 1998/Accepted: 27 March 2000     

The cost of children: May the collective approach to household behavior help?

The collective approach to household consumption behavior tries to infer from variables supposed to affect the general bargaining position of household members information on the allocation of consumptions goods and tasks among them. This paper investigates the extension of previous work to the case where children may be considered as a public consumption good by the two adult members of a household. The main question being asked is whether it is possible to retrieve from the aggregate consumption behaviour of the household and the relative earnings of the parents information on the allocation of goods between them and children. This alternative approach to the estimation of the ‘cost of children’ is contrasted with the conventional approach based on a ‘unitary’ representation of and demographic separability assumptions on household consumption behaviour.

在现实主义和现代主义的视野里寻求和谐生存之道——论D·H·劳伦斯的《儿子与情人》

D.H.劳伦斯在小说《儿子与情人》中,通过批判现实主义手法描述了主人公保罗的爱情悲剧和家庭悲剧,揭示了英国工业文明对自然环境及人类和谐生存状态的破坏。同时,作为一个现代主义作家,劳伦斯探索了人的潜意识及如何在现代文明中构建和谐生存之道。劳伦斯认为,人类只有与自然界保持和谐的关系、重建两性之间和谐、自然的关系,才能克服现代文明社会带来的弊端,实现生存状态的和谐。劳伦斯对人类生存困境的探索不仅为同时代人提供了获得救赎的全新思路,在当今呼唤和谐社会的时代,仍为我们提供了有益的借鉴。
