唐代藉田礼仪演变与书写范式

藉田礼发展到唐代,已经形成相对固定的礼仪规范,同时太宗、 玄宗、 肃宗等在方位、 地点、 流程方面对之进行了灵活的调整,呈现出皇权凌驾于礼仪之上的倾向.与之相应的藉田书写,侧重点也不在于礼仪本身,而在于沟通政治情感,既传达赞美圣君追慕盛世的执政理想,又呈现出君臣交流体贴人情的现实关怀,同时也表达藉田不行于世不被重用的失落蹉跎.这就使得唐代藉田书写不同于《诗经》、汉赋,呈现出礼仪应用文本的特点,形成了藉田祭祀乐歌的礼仪范式、 藉田科场赋颂的结构范式、 藉田题材意象的表达范式.这些范式的生成象征着藉田礼仪文本的成熟,在颂美国家仪典、 寄托文人政治情感的基础上,推动着文以载仪功用的实现.     

A reply to Walker’s note: A comment on Taşiran’s ‘Wage and income effects on the timing and spacing of births in Sweden and in the United States’

Walker (1997) criticizes one of the conclusions in my book Tas?\iran (1995), that Heckman and Walker’s very high negative wage rate and positive income effects on Swedish fertility are very sensitive. In this paper, I explain, first, that my results are not only based on the series Walker mentions, but also on other series in both SFS and HUS data sets. Second, the combined aggregate and micro wage series he criticizes is mainly derived with Heckman and Walker. Third, by discussing the points he raises for the combination strategy, I show that his revised results are also supporting my conclusion. Received: 7 June 1996/Accepted: 16 July 1997 I am grateful to Anders Klevmarken, Lennart Hjalmarsson, Bj?rn Gustafsson and Ann Veiderpass for their valuable suggestions and discussions on an earlier version of this paper. Thanks also to two anonymous referees for their comments and to the responsible editor of this journal Klaus F. Zimmermann, for his encouragement and many helpful comments. Any remaining errors are my own. Responsible editor: Klaus F. Zimmermann.     

中国人造植物肉产业的发展现状、驱动机制与前景预测

以人造植物肉为研究对象,阐述其发展历程和发展现状,梳理植物肉的驱动机制和制约因素,并进行前瞻性预测.结果表明:(1)相比传统肉,人造植物肉在满足消费者健康饮食需求、节约生产要素、降低产出污染等方面具有发展优势.除加强国内畜禽业供给和扩大进口贸易之外,大力发展人造植物肉产业可以作为潜在的第三条路径以适当补充国内肉类供给缺口.(2)当前国内植物肉产业仍处于萌芽发展阶段.2019年国内植物肉产品对传统肉制品的替代率为0.37％,可节约饲料粮99.05万吨.(3)植物肉的后续发展前景值得期待,预测到2050年替代率可增至6.7％,可替代超过1300万吨肉制品和节约4600多万吨饲料粮.基于此,研究结论对促进中国植物肉产业发展、激励畜禽业转型和保障饲料粮安全有着重要的政策启示.

壮族民间信仰研究的成果、独特价值及未来趋向

本文从自然崇拜、始祖崇拜、师公教、娅汪女神四个研究专题梳理了改革开放以来壮族民间信仰研究的已有成果,探讨了壮族民间信仰研究的独特价值,对比了壮族民间信仰研究与全国民间信仰研究在研究动态和研究取向上的差异,并将其视为今后研究的突破口,认为壮族民间信仰研究有以下发展趋向:继续深化对民间信仰"壮族模式"的研究、加强对壮族民间信仰复兴和再造的研究力度、注重对民间信仰仪式实践的考察;并认为多学科、跨学科的综合研究将会得到强化.     

藏族早期民间信仰的形成及佛苯融通和适应——五、六世纪宕昌的家藏苯教古藏文写本

苯教是青藏高原土生土长的本土宗教,也是藏族文化的源泉;苯教文献是古代藏族人民在人类文明史上留下的辉煌篇章。甘肃宕昌藏族家藏苯教文献,是研究和认识藏族及其文明的极其重要的历史文献资料,尤其是研究7—9世纪甚至5—6世纪以前藏人的思想、哲学、宗教、政治、经济、文化、科学技术等的弥足珍贵的资料,是开掘苯教文化、承续藏族远古文明薪火的重要文本。本文对宕昌家藏苯教写本文书考察和收集进行综合述评,并对苯教渊源考述、佛苯融通及苯教文化的适应谈了自己的观点。     

“She was buried in her purple dress and her red hat and all of our members wore full ‘Red Hat Regalia’ to celebrate her life”: Dress, embodiment and older women's leisure: Reconfiguring the ageing process

There is a significant literature on women's dress and clothing, women's dress and identity, and women's dress and body image. However, the way that dress shapes the self, gives public meaning to the body, and situates it within culture—its embodiment—is understudied. Older women's voices on how dress-up in leisure contexts is linked to embodiment are absent. Using data from an online survey of the Red Hat Society®, a leisure-based social group with over 1 million members, we examined the relationship between older women's dress and embodiment. Data analysis revealed three themes: 1) Dress and embodiment, doing “dress-up”; 2) Dress and embodied subjectivity, linking the personal with the social; and, 3) Dress and perceptions of ageing, fashioning to freedom. We extend the embodiment and leisure literatures by: (a) including older women's viewpoints on dress; (b) understanding linkages between embodiment and older women's leisure; and, (c) illustrating how public displays of dress contribute to older women's development.

Joint chance-constrained staffing optimization in multi-skill call centers

This paper concerns the staffing optimization problem in multi-skill call centers. The objective is to find a minimal cost staffing solution while meeting a target level for the quality of service (QoS) to customers. We consider a staffing problem in which joint chance constraints are imposed on the QoS of the day. Our joint chance-constrained formulation is more rational capturing the correlation between different call types, as compared to separate chance-constrained versions considered in previous studies. We show that, in general, the probability functions in the joint-chance constraints display S-shaped curves, and the optimal solutions should belong to the concave regions of the curves. Thus, we propose an approach combining a heuristic phase to identify solutions lying in the concave part and a simulation-based cut generation phase to create outer-approximations of the probability functions. This allows us to find good staffing solutions satisfying the joint-chance constraints by simulation and linear programming. We test our formulation and algorithm using call center examples of up to 65 call types and 89 agent groups, which shows the benefits of our joint-chance constrained formulation and the advantage of our algorithm over standard ones.

     

高校学报编辑满意度调查分析

基于工作说明量表与洛克量表的有机结合,采用问卷调查法对高校学报编辑满意度进行了调查分析。分析表明,编辑的人生观、价值观取向基本趋于一致,编辑对上司、工作本身、同事、沟通的满意度较高;对认同感、福利、报酬的满意度居中;对晋升和规章制度的满意度较低,而且不同属性对编辑工作满意度的评价绝大多数没有显著性差异。
