杜诗自注与诗歌境域的开拓

杜甫诗歌的自注作为中国诗歌自注体的早期代表,记录下了与诗歌创作相关的丰富信息,充分发挥了诗歌自注体的辅助功能,诗与注的紧密互动对杜甫诗歌的情志表现产生了一定的积极影响。杜甫再次介入诗歌进行自我诠释的动机反映了诗人对创作的自省心理,流露出其多方开拓新境的诗学追求。     

Work rehabilitation for migrant workers with work injury--the magic of Chinese paper cutting

As China has gradually transformed from agricultural economy into industrial economy since 1978, occupational injuries and diseases become a serious social problem in China. For occupational rehabilitation professionals, helping workers with occupational injuries and diseases, return to work and re-integrate to community are the ultimate goals of occupational rehabilitation. This article reports a new indigenous initiative with cultural notions in occupational rehabilitation piloted by Guangdong Provincial Rehabilitation Center. Case studies reflected that by learning and practicing traditional Chinese paper cutting, workers with occupational injury and disease could regain their self confidence, identity their strengths, learn more vocational skills as well as to re-integrate into community.     

新疆维吾尔族桑皮纸的研究与应用

本文对新疆维吾尔族桑皮纸的历史、维吾尔族民间制作工艺和应用等情况进行了探索性研究。桑皮纸在新疆非常古老,历史很久远,而新疆的桑皮纸历代生产以和田地区为中心,古老的和田孕育了悠久的桑皮纸历史文化和民间制作工艺技术。桑皮纸最大特点是结实而有韧性、柔嫩、防虫、拉力强、不褪色、吸水力强,主要用于书画装裱、包扎纸币、制伞、包装、制鞭炮,此外,还被用在印钱、制扇、印刷书籍等文化工艺生产活动中。     

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.

     

金圣叹论文学创作心理

金圣叹的评点理论对创作心理给予了较多的关注,他不但探讨了创作动机产生的心理原因,还对构思心理活动中起关键作用的心理因素——想象作了深入的论述。他还认识到创作构思心理活动和表达存在两种不同的情况,一种是边构思边表达。一种是表达之前已经完成了构思。     

We're All in This Together: Context, Contacts, and Social Trust in Canada

How do conditions of diversity and inequality affect the sense of solidarity with each other that is manifested as social trust? This article brings together the literatures on racial heterogeneity, inter-group contact and relative deprivation to test and enrich the existing theoretical understanding of trust. It explores the effects of city and neighborhood contexts, individual experiences of inter-group relations, and their moderating effects on social trust. Findings suggest that the influence of a city's level of ethnic/racial diversity and income inequality is conditioned by inter-group social ties and experiences of discrimination. By considering the characteristics of neighborhoods, racial diversity of cities no longer has any significant association with trust in others. However, income inequality at the city level interacts with experiences of discrimination to undermine trust. Public policies aimed at improving social cohesion would benefit from considering the joint impact of economic and social policies that regulate resource distribution and hence shape inter-group relations.     

《喧哗与骚动》的时间叙事方法

福克纳的著名小说《喧哗与骚动》是受到广泛评论的文学作品之一，文章仅从其第二章入手，解析他利用“时间”的叙事方法来刻画出一个极度扭曲的灵魂，以及他以“时钟时间”和“心理时间”的不对等关系剖析主人公昆丁所表现出来的时间错位所带来的深刻隐喻。     

工作经验一定有助于创业过程吗:基于工作内嵌入的分析

国内外大量研究发现,工作经验对创业过程起着重要的促进作用。但是以往研究尚无法解释为什么有工作经历的创业者创业的成功率存在巨大差异的问题。基于此,本文借鉴人力资源管理领域的工作嵌入模型,运用美国创业动态跟踪研究(Panel Study of Entrepreneurial Dynamics I,简称PSEDI)的调查数据,运用多元回归分析方法对创业者先前的工作内嵌入对创业活动的集中性和创业周期长短的影响进行了实证分析,发现创业者的先前工作经验可能导致创业活动分散和创业活动周期延长。该结论更为全面地解释了工作经验对创业过程的影响机理,同时也有助于启发有创业打算和创业潜力的个体合理地利用以往的工作经验,提高创业活动的成功率。
