"三元"说之宗宋及其诗学价值指向

"三元"说是陈衍针对今人强分唐宋诗与扬唐抑宋的诗学观所提出的诗学纠偏策略.它以三元皆盛之论,将唐宋诗并列,同时又立足于宋诗,特别以杜、韩、黄为重心,突出宋诗对唐诗的创变与突破,从而确立宋诗地位与特征,对扬唐抑宋诗学观进行纠偏.这一诗学之根本,不在纠缠于诗歌诗艺形式上的高下判别,而关注内容精神之追求.以提倡变风变雅、振兴诗教为旨归,寄寓着关注现实人生的重要的诗学思想.     

国际权力与秩序变革

权力是行为者将其意志强加于其他行为者之上的能力.在任何政治秩序中,权力都是不可或缺的组成部分.世界秩序的变更,是由于该国际体系的现存统治方式与权力的重新分配之间发生了断裂.冷战后国际体系的权力结构发生了重大变革,这就必然导致世界秩序的变革.而世界秩序的和平变革,必须在权力和道德两者之间寻求艰难的妥协.     

Continuity and change in work-life balance choices

This paper explores the ways in which the work-life balance choices made by heterosexual couples differ in different generations, how such choices are gendered, and the extent to which 'individualization' provides an adequate conceptualization of the effects of social change on heterosexual couples. It argues that processes of individualization need to be seen in the context of changing social institutions, and that it is the de-institutionalization of 'the family' and the life course that is leading to a de-gendering of work-life balance choices. The paper draws on findings from a restudy of the family and social change and a study of the gender dimensions of job insecurity both of which were carried out in the same geographical location. The studies provide evidence of generational change in work-life balance choices and increasing occupational differentiation between heterosexual partners. This leads to a situation where increasingly choices are made which blur gendered boundaries and which has been made possible by a process of de-institutionalization of the male breadwinner family. Our findings support the contention that processes of individualization are more apparent amongst younger than older generations and that, because of changes external to the family, there is more negotiation and pragmatism amongst younger generations about work-life choices.     

Making Sense of Organizational Change: Voices of Older Volunteers

The role of voluntary and community sector organizations in the delivery of public services is increasing and these changes bring new responsibilities and benefits to organizations that have the capacity to participate. There are concerns within the sector about the implications for citizenship and participation. The sector is highly dependent on volunteers yet little is known about how organizational change in response to new relationships with the statutory sector impact upon the commitment and well-being of people who volunteer. This paper addresses that gap in knowledge for older volunteers. Drawing upon collaborative research with a voluntary organization in the north of England, the authors explore the meanings and aspirations of volunteering for older people, and explain how and why changes associated with closer engagement with public service delivery and less grant dependency can be disempowering for them.

一种求解双目标flow shop排序问题的进化算法

提出一种求解双目标flow shop排序的递进多目标进化算法.算法采用改进的精英复制策略,在实现精英保留的前提下降低了计算复杂性;通过递进进化模式增加群体多样性,改善了算法收敛性;通过群体进化过程中对非劣解集进行竞争型可变邻域启发式搜索,增强了算法局部搜索性能.采用新算法和参照算法NSGA-II对31个标准双目标flow shop算例进行优化.研究结果表明,新算法在所有算例的求解中均获得了优于NSGA-II的非劣解集,验证了算法的有效性.

Identifying and implementing pathways for organizational change – using the Framework for the Assessment of Children in Need and their Families as a case example

Change within social work organizations is incessant. This has implications for senior managers and elected members who have to manage these changes. The Department of Health has introduced new guidance entitled the Framework for the Assessment of Children in Need and their Families ( Department of Health 1999a ). The guidance is based on a number of principles that require an attitudinal shift in terms of assessing ways of safeguarding children and promoting their welfare. This paper describes strategic approaches to the effective introduction of the framework within social services departments and other child welfare organizations. Two models have been adapted from practice: the actual framework for assessing children and their families and the Protchaska and DiClementi model of change. These models complement each other. The adapted Assessment Framework provides a structure to assess the readiness of the organization for the implementation of the new framework. The model of change provides a schema for planning, implementing and reviewing the introduction and operation of the Framework for the Assessment of Children in Need and their Families. Although the focus of the paper is the introduction of the new guidance , the models can be utilized by senior managers in any social care organization who are facilitating major changes in the organization.     

Time‐change models for asymmetric processes

Many records in environmental sciences exhibit asymmetric trajectories. The physical mechanisms behind these records may lead for example to sample paths with different characteristics at high and low levels (up–down asymmetries) or in the ascending and descending phases leading to time irreversibility (front–back asymmetries). Such features are important for many applications, and there is a need for simple and tractable models that can reproduce them. In this paper, we explore original time‐change models where the clock is a stochastic process that depends on the observed trajectory. The ergodicity of the proposed model is established under general conditions, and this result is used to develop nonparametric estimation procedures based on the joint distribution of the process and its derivative. The methodology is illustrated on meteorological and oceanographic data sets. We show that, combined with a marginal transformation, the proposed methodology is able to reproduce important characteristics of the data set such as marginal distributions, up‐crossing intensity, and up–down and front–back asymmetries.
