The dynamics of time use: Context and meaning

In this article, earlier work on the organization of the household day is revisited to bring a sociological perspective to the study of household time. There is much to be gained from elaborating the conceptualization and measurement of time use to acknowledge and the employment of its dynamic qualities and meanings. That is, analysis of household time use must become far more than a longitudinal accounting process. In this article, no roadmap to such a destination can be provided but perhaps movement in a new direction. The practical application of insights from research on household time use requires conceptual frameworks that allow household time to be depicted as it unfolds and as participants experience it. That is, serious attention might be lent not only to studying where time is spent but also to how activities are situated and experienced in time to realize human affairs.She is the author ofThe Gender Factory: The Apportionment of Work in American Households, and in 1995 she coeditedindividual Voices, Collective Visions: 50 Years of Women in Sociology, published by Temple University Press. Her current work focuses on the theoretical articulation of race, class and gender in women's work.This paper required a good deal of reflection on a project I undertook with Richard A. Berk in 1975. I am grateful for his comments and suggestions.     

犯罪构成动态论纲

传统的犯罪构成理论以对构成犯罪的各要件分析见长,但综合不够,动态研究欠缺.从动态角度研究犯罪构成非常重要,从理论角度看,它对统摄诸如形态论、转化犯等问题有意义;在实践方面,对准确地定罪量刑也有重大作用.这可从方法论、总论、分论三个方面进行分析.     

尖镰孢菌F.oxysporum L19内切纤维素酶诱导碳源的研究

以在自然界中筛选到的一株产纤维素酶的丝状真菌尖镰孢菌F.oxysporumL19为材料,定时测定尖镰孢菌在10种碳源中的纤维素酶活力,发现酶的合成受培养基中碳源种类的调节控制。结构相对完整的纤维类物质(微晶纤维素、TYPE50、CMC、醋酸纤维素)诱导活性较高,二糖(乳糖、麦芽糖、蔗糖)和单糖(葡萄糖和D-木糖)几乎没有诱导作用,麸皮汁液体培养液表现出了较高的诱导活力。菌丝在麸皮汁培养液上的生长状况的研究表明,菌丝的生长情况与酶的产生存在不同步性。这为下一步酶的纯化和分子生物学的研究中选择不同生长期的培养也提供了依据。     

浅论语境理论

旨在联系传统的静态语境和现代的动态语境分析 ,认为传统研究虽采用静态方法 ,出现描写能力过强的问题 ,但取得的成就不容忽视 ,而以顺应和认知理论为代表的动态语境观正是站在传统研究的基础上才形成系统的理论体系和完善语境的研究。     

一致性意识形态与当代中国制度变迁的动力学

当代中国的制度变迁是由政治家主导的,这一制度变迁的动力学在很大程度上可以用新的一致性意识形态来说明。事实上,如果没有新的一致性意识形态,中国的制度变迁是不可能取得成功的。     

量化模型用于动态土地利用总体规划实施评价的研究

研究目的:建立一套操作性强的动态土地利用总体规划实施评价的指标体系和评价方法;研究方法:设计实施评价的指标体系和量化模型,运用层次分析法对上一轮土地利用总体规划进行评价;研究结果:运用量化模型建立动态土地规划实施评价可以在规划实施期监督土地使用情况、规范政府用地行为、依法保护国土资源;研究结论:动态的土地利用实施评价对于实现土地规划的最优化有重要作用。     

从动态顺应看《李尔王》的三种译本

Jef Verschueren的语用综论观下的顺应论的动态性认为,语言选择过程的动态顺应可以从三个方面得到体现:时间顺应、语境的顺应和语言线性结构的灵活变化。以该理论对《李尔王》三个不同时期的译本进行分析,指出翻译标准应该被不断地重新阐释以顺应不同时间、不同语境和不同交际目的。     

时空观演变对中晚唐诗风的影响

时空观是唐人个体觉醒的产物 ,也是诗风嬗变的关键。从中唐开始 ,时空观经历了一个从持续性、广延性向交替性、破碎性转变 ,从外张向内聚发展的过程。与之相适应 ,唐代的诗风也经历了多次变化。在与时空世界的矛盾中 ,唐人终于选择了承担 ,显示了刚健的生命力度 ,也赋予了诗歌巨大的张力     

基于Lennard-Jones和Soft-Sphere势能模型的流体传递性质分子动力学模拟比较

利用分子动力学模拟计算传递性质方法，采用Green-Kubo关系式基于Lennard-Jones势能模型和Soft-Sphere势能模型模拟了速度相关函数、压力张量相关函数、热流相关函数以及它们对应的传递系数，讨论了Lennard-Jones势能分子间吸引力和Soft-Sphere势能“软度”对流体传递性质的影响．     

Panel regression models for measuring multidimensional poverty dynamics

This work concerns the study of poverty dynamics and the analysis of the influencing socio-demographic factors. A fuzzy and multidimensional approach has been chosen in order to define two different poverty measures. A panel regression model has been estimated and particular attention has been paid to the treatment of the unobservable heterogeneity among longitudinal units. The specified model combines autoregression with variance components. The empirical analysis has been conducted using the data set of the British Household Panel Survey (BHPS) from 1991 to 1997. This work was co-financed by Murst funds for the projects “Occupazione e disoccupazione in Italia: misura e analisi dei comportamenti”. The paper is the result of the common work of all the authors; in particular G. Betti has written Sects. 2,5.1 and 5.3.1; A. D’Agostino has written sections 4, 5.2 and 5.4; L. Neri has written Sects. 1, 3, 5.3.2 and 6.
