The increase in marital status differences in mortality up to the oldest age in seven European countries, 1990-99

We investigate mortality differentials by marital status among older age groups using a database of mortality rates by marital status at ages 40 and over for seven European countries with 1 billion person-years of exposure. The mortality advantage of married people, both men and women, continues to increase up to at least the age group 85-89, the oldest group we are able to consider. We find the largest absolute differences in mortality levels between marital status groups are at high ages, and that absolute differentials are: (i) greater for men than for women; (ii) similar in magnitude across countries; (iii) increase steadily with age; and (iv) are greatest at older age. We also find that the advantage enjoyed by married people increased over the 1990s in almost all cases. We note that results for groups such as older divorced women need to be interpreted with caution.     

The Longitudinal Interplay of Maternal Warmth and Adolescents' Self‐Disclosure in Predicting Maternal Knowledge

This study examined the longitudinal associations among maternal warmth, adolescents' self‐disclosure, and maternal knowledge during the transition to adolescence. Three years of self‐report data were collected from 131 married mothers and their adolescents. Results from longitudinal analysis using adolescent reports indicated that greater maternal warmth in sixth grade predicted higher levels of adolescents' self‐disclosure in seventh grade, which in turn led to higher levels of maternal knowledge in eighth grade. Thus, adolescents' self‐disclosure served as an indirect link between higher maternal warmth and greater knowledge over time. An alternative model with prior self‐disclosure predicting subsequent maternal warmth and knowledge was not supported. Overall, this study demonstrated a time‐ordered process by which maternal warmth and adolescents' self‐disclosure predict maternal knowledge. Understanding such processes that affect parental knowledge may be beneficial for future prevention and intervention efforts during the transition to adolescence.     

Energy modelling: A new challenge for management science

The Arab oil embargo in 1973 and the subsequent price rises and production restrictions have given birth to a distinct branch within Management Science: energy modelling. This paper gives a critical and selective review on energy modelling, an industry which though thriving in an era of general economic anxiety, is showing signs of arrogant immaturity. After giving a historical background, the paper classifies energy models into three groups: open loop demand or supply models; energy closed loop models; energy-economy closed loop models. For each group the problem area is analysed and some illustrative examples are described. In the last sections, an attempt is made to sum up the experience that has been gained with energy modelling: the basic deficiencies, the impact of this activity on policy formulation and its position within Management Science. It is concluded that energy models, though very poor forecasting devices, can be very useful to policy makers as tools for analysis; energy model developers must convince potential model users and for that purpose they can benefit immensely from the 35-year-long experience accumulated by their colleagues in Management Science.     

Large scale communication networks—Design and analysis

The paper discusses the problem of design and analysis of large scale communication systems. An iterative process, composed of a minimum cost network design algorithm and a network performance algorithm, is presented for the solution of these problems. Computational considerations, using these algorithms, are discussed.     

The use of strategic planning techniques in the United Kingdom

In this paper some of the techniques available for strategic planning are reviewed. Four techniques are presented, the experience curve, the growth-share matrix, the directional policy matrix and the PIMS program. The results of a survey into the use of these techniques in the United Kingdom are also presented.

近四十年来韩国《史记》研究综述（1971—2010）

《史记》是中国史学中一部继往开来的不朽巨著,作者司马迁开创的以人物为中心的纪传体,在汉代以后一直是历代王朝正史所沿用的体制。司马迁修《史记》,不仅尊重历史事实,秉笔直书,而且还注意语言文字的锤炼,文句优美。他将叙事、抒情、说理的不同文体有机地综合起来,达到思想上、艺术上的高度统一,为后代文史创作提供了范例。《史记》不仅是中国纪传体史书的开创者,而且对后世的散文、小说、戏曲都产生了深远的影响。同时它也早已流传至国外,在汉文化圈国家中亦有不小的影响。其中,《史记》传入韩国,特别受到韩国知识界人士的关心和推崇,为韩国学术界所重视。到了1960年代中期,随着国家经济的发展,韩国整个社会的发展进入了一个历史的新时期,不仅国家面貌发生了根本性变化,学术文化事业也步入正轨,同时韩国学术界对中国学术文化的关心及研究也重新得到了高度重视。正是在这样的基础上,韩国学者对《史记》的翻译和研究有了较大的进展,在传播、普及和通俗化方面作出了积极的贡献。本文除简述《史记》在韩国的流传背景外,还分别论述自1971年至2010年近四十年来《史记》在当代韩国的翻译介绍与研究现状,并对其研究成果上存在的一些不足和空缺作一番客观的评价。     

Serving the urban poor: a study of child welfare preventive services.

This summary, for journal publication, of a study whose full details are being published in book form, brings the welfare field up-to-date on what began as a precedent-setting agency. The Lower East Side Family Union, in New York City, has provided many years of service, and has justifiably drawn national attention from its inception, when prevention was more talked about than funded. The lessons to be drawn from its work and the example it has set grow more timely every year.     

Using strategic planning to drive strategic change

This article describes a case history of strategic planning, learning and change within a major division of Dowty plc. At Dowty CASE, a telecommunications company, the management team used strategic planning as a structured learning process to generate strategic change. There are many lessons which academics and practitioners alike can learn from this case of strategic planning and change in action.
