Wang Shuo and the commercialisation of contemporary Chinese culture
Full text linkThis thesis examines the commercialisation of Chinese culture that has taken place over the past twenty years in mainland China. It explores the contribution of Wang Shuo, a cultural figure who straddles different fields of culture, moving from literature to the ultimate mass culture medium of television, this study plots Wang Shuo' s development from educational failure, to business failure, to fiction writer, film & TV editor, film director and cultural critic and analyst. His stories, films, TV series and articles have caused shock-waves throughout national cultural circles as he has transformed the terms of the debate from academic discourse to a validation of the role of the market in the culture field. Although Wang Shuo has not been labelled as a dissident, his approach to the culture market has had a more subversive effect on official ideology that those overt dissidents who have had to live in exile or have been imprisoned. He has utilised the language of official ideology to satirise the authorities, turning the ideology and its supporters into figures of fun. Yet his own goals have been strictly personal and economic ones. The authorities recognize the value of Wang Shuo's work in the cultural market but at the same time distrust his works and place him under strict censorship. Examining the way Wang Shuo and people surround him have succeeded in different fields of cultural achievement is a mirror to understanding the process of the transformation of contemporary Chinese culture from a socialist state-controlled culture to a market-oriented mass culture industry
Extreme-Point-based Heuristics for the Three-Dimensional Bin Packing problem
Full text linkOne of the main issues in addressing three-dimensional packing problems is finding an efficient and accurate definition of the points at which to place the items inside the bins, because the performance of exact and heuristic solution methods is actually strongly influenced by the choice of a placement rule. We introduce the extreme point concept and present a new extreme point-based rule for packing items inside a three-dimensional container. The extreme point rule is independent from the particular packing problem addressed and can handle additional constraints, such as fixing the position of the items. The new extreme point rule is also used to derive new constructive heuristics for the three-dimensional bin-packing problem. Extensive computational results show the effectiveness of the new heuristics compared to state-of-the-art results. Moreover, the same heuristics, when applied to the two-dimensional bin-packing problem, outperform those specifically designed for the proble
Construction heuristics for two-dimensional irregular shape bin packing with guillotine constraints
No full textThe paper examines a new problem in the irregular packingliterature that has existed in industry for decades;two-dimensional irregular (convex) bin packing with guillotineconstraints. Due to the cutting process of certain materials, cutsare restricted to extend from one edge of the stock-sheet toanother, called guillotine cutting. This constraint is commonplace in glass cutting and is an important constraints intwo-dimensional cutting and packing problems. In the literature,various exact and approximate algorithms exist for finding the twodimensional cutting patterns that satisfy the guillotine cuttingconstraint. However, to the best of our knowledge, all of thealgorithms are designed for solving rectangular cutting where cutsare orthogonal with the edges of the stock-sheet. In order tosatisfy the guillotine cutting constraint using these approaches,when the pieces are non-rectangular, practitioners implement a twostage approach. First, pieces are enclosed within rectangle shapesand then the rectangles are packed. Clearly, imposing this condition is likely to lead to additional waste. Thispaper aims to generate guillotine-cutting layouts of irregularshapes using a number of strategies. The investigation comparestwo two-stage approaches; one approximates pieces by rectangles,the other approximates pairs of pieces by rectangles usingphi-functions for optimal clustering. Both these approaches usestate of the art rectangle bin packing with guillotineconstraints. Further, we design and implement a one-stage approachusing a self-adapted forest search algorithm. Experimental resultsshow the one-stage strategy to produce good solutions in less timeover the two-stage approach

TS2PACK: A Two-Level Tabu Search for the Three-dimensional Bin Packing Problem
Full text linkThree-dimensional orthogonal bin packing is a problem NP-hard in the strong sense where a set of boxes must be orthogonally packed into the minimum number of three-dimensional bins. We present a two-level tabu search for this problem. The first-level aims to reduce the number of bins. The second optimizes the packing of the bins. This latter procedure is based on the Interval Graph representation of the packing, proposed by Fekete and Schepers, which reduces the size of the search space. We also introduce a general method to increase the size of the associated neighborhoods, and thus the quality of the search, without increasing the overall complexity of the algorithm. Extensive computational results on benchmark problem instances show the effectiveness of the proposed approach, obtaining better results compared to the existing one

“Chinese Identity” as a Problem
Full text linkIn this short report, Wang Bin wonders about the issues related to language when it comes to talking about Chinese identity. While qualifying a relativist cultural approach, he opposes a holistic conception of identity which would look for the authentic in the atemporal. By basing his research on the different uses of words representing China and the Chinese in various languages, Wang Bin depicts an aspect of the Chinese collective identity which complex reality can not be expressed formally
