论虚实关系在舞美设计中的运用

虚与实是艺术创作技巧的美学原则,在舞台美术设计中,更显示出虚实结合的独特性和必要性,具体来说,表现在几个方面:在布景设置上,要以实带虚,以虚衬实;在意境表达上,要虚实对比,和谐产生;在光色处理上,要虚实变幻,以景托人;在舞台布局上,要讲究整体,统筹协调.

Multi-Item Grouping Algorithm Yielding Near-Optimal Logistics Cost

This article describes an algorithm used to formulate an inbound consolidation strategy when multi-items are replenished in groups and when total logistics cost is to be minimized. The importance of this algorithm is threefold (1) no optimal procedure exists for grouping multi-items when minimizing total logistics cost, (2) a complete enumeration of all possible groups (from which the optimal grouping set can be identified) is impractical due to the combinatorial nature of the grouping problem, and (3) no other heuristics have been developed that adequately reflect shipping cost in the analysis like this one does. We report the experience of using this algorithm to group and reorder 75 selected ensembles containing a total of 517 inventory items of a retail merchandising firm.     

Solution Procedures for the Lot-Streaming Problem

Lot streaming is the process of splitting a job into sublots so its operations can be overlapped and its progress accelerated. We present a computationally efficient procedure for solving the m-machine, two-sublot problem, and we discuss the bottleneck insights that emerge from the analysis. We also examine heuristic approaches for more than two sublots and discuss computational results for these procedures.     

On Sampling Error in Market Share Estimates*

The relative error in the usual estimator of a brand's market share is reformulated in terms of marketing parameters. Such error is shown to be influenced in an important way by market penetration, as well as by variation in brand and product category volume. Of particular interest is the result that the relative error does not depend on the actual share level. Using data from a marketing research firm that supplies share estimates to the health products industry, we find that the relative error may be substantial even when a large sample is available. An upper bound on this relative error is obtained using marketing parameters that can frequently be measured using industry data and a company's internal records, thus reducing the level of judgmental input required in the planning of sample surveys.     

Parents’ perspectives of social support and social cohesion in urban contexts of diversity

Although provisions for young children are increasingly considered as ideal places to foster an inclusive and socially just society by embracing issues of social support and social cohesion, there is no in-depth understanding of the role these provisions can play in enabling supportive and cohesive encounters in contexts of diversity. Even more striking is the absence of parents’ voices in this discussion. Based on an analysis of qualitative interviews with 18 parents who use childcare services in urban contexts of diversity, our findings show the relevance of ephemeral contacts with diverse people that could offer bridging opportunities in terms of social connectedness to familiarise within diversity while decoding the other in urban contexts of diversity. However, neither bonding nor bridging contacts appear as self-evident. Our research shows that the role of childcare services might be vital in creating light and temporal communities as the prerequisite for social cohesion to flourish, in both individual as well as collective dimensions.     

Tea Art as Everyday Practice: Gongfu Tea in Chaoshan,Guangdong, Today

In recent decades a style of preparing and drinking tea modelled largely on gongfu tea associated with the Chaoshan region of north-eastern Guangdong Province, China, has been taken up as a contemporary tea art in Taiwan, Hong Kong, the Chinese mainland and elsewhere. This paper draws on fieldwork conducted in Chaoshan to examine gongfu tea as contemporary practice in its home setting. Three aspects are considered: gongfu tea as an everyday practice, as a refined practice, and as commercialised leisure in tea-houses. I argue that, as an everyday practice in Chaoshan, gongfu tea primarily serves to nourish social connectedness with family, friends and associates. It is regarded as an integral part of day-to-day life rather than a tea art. However, some people separate it from the everyday world by cultivating discernment and knowledge with regard to selected aspects, such as high-quality teapots or appreciation of different teas.     

Reducing attitudes of prejudice and discrimination through literature: a quasi-experiment on the upper key-stage 2 students of the British schools in Karachi,Pakistan

This study aims to explore the efficacy of literature relating to Anne Frank to reduce children’s attitudes of prejudice and discrimination with respect to specific dimensions, including ethnicity and race, religion and gender. A quasi-experiment was employed with pre-post control design. The sample consisted of 100 students of the upper key-stage 2 (UKS2) level, recruited from the two British schools in Karachi. These schools represented an Experimental Group (EG) and a matched Comparison Group (CG). A research instrument titled ‘Muggles world of differences’ (MWD) was developed and validated. It was administered on CG and EG, both before and after intervention. The intervention plan ‘Reading of Young Anne’s Literature’ (ROYAL) was developed based on selected readings from Anne Frank related literature (AFL). Intervention was provided to EG, while CG studied similar concepts using a more standard method. Results of the pretest revealed a high level of prejudice and discrimination in both the EG and CG, with no significant difference (p > 0.05) in the overall scores, as well as in the specific content domains. However, the post-test of the two groups revealed that the students in the EG had outperformed their CG counterparts in overall MWD scores, as well as in specific content domains. The difference was found to be significant (p < 0.05) with the large effect size (r = ?0.63). Results support the efficacy of teaching Anne Frank related literature in reducing attitudes of prejudice and discrimination.     

Elementary School-age Children's Attitudes Toward Children in Same-Sex Parent Families

As numbers of families with same-sex parents increase in the United States, children are more likely to encounter diverse family structures. Given that young children can demonstrate in-group bias, prejudicial attitudes, and social exclusion, it is important to understand how children perceive their peers in diverse families. To our knowledge, no studies have assessed elementary-school-age children's attitudes about same-sex parent families. Here, 131 elementary school students (M_age = 7.79 years; 61 girls) viewed images of same-sex (female and male) and other-sex couples with a child and then were asked about their perceptions of these families, particularly the children. Results indicated participants' preferences toward children with other-sex versus same-sex parents. Developmental and practical implications about children's attitudes toward sexual minority parent families are discussed.
