International Airports: Passengers in an Environment of ‘Authorities’

This article looks at airports from the passengers' perspectives. It shows that international airports are, above all, spaces of highly explicit expressions of several authorities. The article first distinguishes between airline and airport geographies, followed by a conceptual analysis of authority, power and airports. Then, the article describes the several airport authorities and their responsibilities, spelling out their control of the physical elements of airport terminals, with special attention to signage. This is followed by discussions of airport terminal operations and resulting passenger flows, once again focusing on the role of multiple authorities. These discussions lead, finally, to expositions of travelers' socialities while at international airport terminals and under an authoritarian regime, focusing on passengers' disembodying and dialectics.     

基于修正C-D函数模型的技术进步与经济增长测算——以甘肃省为例

利用修正的生产函数较好地估计了甘肃省资本、劳动和技术进步对经济产出的贡献份额。结果显示,资本投入对经济产出贡献较大,技术进步对经济产出效果不理想,而劳动对产出贡献处于较低水平,经济发展主要依靠资本高投入带动,经济发展还处于粗放式阶段,这种模式是不可持续的。为了可持续发展,必须提高要素转化效率,提高劳动者素质和职业技能。

Alcohol’s Effects on Video Lottery Terminal (VLT) Play Among Probable Pathological and Non-Pathological Gamblers

This study tested whether alcohol increases behaviors associated with video lottery terminal (VLT) play, particularly among probable pathological gamblers. Forty-four regular VLT players were designated either probable pathological gamblers or non-pathological gamblers on the basis of scores on the South Oaks Gambling Screen (SOGS); [Lesieur & Blume (1997). American Journal of Psychiatry, 144, 1184–1188] Gamblers from each SOGS category were randomly assigned to either a moderately intoxicating alcohol dose or a control beverage condition (n = 11 per cell in the 2 × 2 between-subjects design). Following beverage consumption and absorption, participants played a video poker VLT game for up to 30 minutes. Four behaviors were measured: “power-bets” (doubling bet after viewing only two cards of the five-card poker hand); total money spent; mean bet magnitude; and number of minutes played. Alcohol increased time spent playing and rate of power-bets, particular among the probable pathological gamblers. Post hoc analyses revealed that alcohol also influenced the proportion of losing hands played––increasing them among the probable pathological gamblers while decreasing them among the non-pathological gamblers. Clinical and policy implications of the findings are discussed.     

集装箱码头外部集卡预约优化模型与算法

针对集装箱码头闸口拥堵问题,建立集卡预约优化模型,目的是减少集卡排队等待时间和拥堵期间的碳排放。该模型在给定的集卡到达调整量水平的限制下,确定每个时段最优的预约份额,同时利用非平稳排队模型描述集卡到达随时间到达的特点。为求解模型,设计基于遗传算法与逐点固定流体近似算法(PSFFA)的求解方法,该算法利用遗传算法搜索最优解,基于PSFFA算法计算集卡排队时间。最后,利用算例对模型和算法的有效性进行了验证。结果表明,集卡预约优化模型可以有效地减少集卡排队时间,PSFFA方法可以较好地求解到达过程不平稳的排队问题。     

亦论《五方元音》的入声

《五方元音》一书存有入声，这是一种假象，是为了迁就传统韵书的需要，是折中的产物，其实《五方元音》时代的广大北方地区入声已经普遍消失。     

Polynomial Time Approximation Scheme for the Rectilinear Steiner Arborescence Problem

Given a set N of n terminals in the first quadrant of the Euclidean plane E ², find a minimum length directed tree rooted at the origin o, connecting to all terminals in N, and consisting of only horizontal and vertical arcs oriented from left to right or from bottom to top. This problem is called rectilinear Steiner arborescence problem, which has been proved to be NP-complete recently (Shi and Su, 11th ACM-SIAM Symposium on Discrete Algorithms (SODA), January 2000, to appear). In this paper, we present a polynomial time approximation scheme for this problem.

Manipulations of the Features of Standard Video Lottery Terminal (VLT) Games: Effects in Pathological and Non-Pathological Gamblers

The present study was conducted to identify game parameters that would reduce the risk of abuse of video lottery terminals (VLTs) by pathological gamblers, while exerting minimal effects on the behavior of non-pathological gamblers. Three manipulations of standard VLT game features were explored. Participants were exposed to: a counter which displayed a running total of money spent; a VLT spinning reels game where participants could no longer stop the reels by touching the screen; and sensory feature manipulations. In control conditions, participants were exposed to standard settings for either a spinning reels or a video poker game. Dependent variables were self-ratings of reactions to each set of parameters. A set of 2(3) × 2 × 2 (game manipulation [experimental condition(s) vs. control condition] × game [spinning reels vs. video poker] × gambler status [pathological vs. non-pathological]) repeated measures ANOVAs were conducted on all dependent variables. The findings suggest that the sensory manipulations (i.e., fast speed/sound or slow speed/no sound manipulations) produced the most robust reaction differences. Before advocating harm reduction policies such as lowering sensory features of VLT games to reduce potential harm to pathological gamblers, it is important to replicate findings in a more naturalistic setting, such as a real bar.     

基于顾客需求偏好的面向无人零售终端的供应链资源整合优化研究

面向新零售的无人零售终端所关注的焦点是如何为顾客提供满意的购物体验。目前,无人零售终端在提供服务时较多关注不同场景下顾客对商品类型的需求,而往往忽略价格、品质和终端操作便捷性等其他差异化的需求。而无人零售的无人值守、需要灵活补货和配货等特点,决定了其在提供差异化服务时,离不开供应链网络的有效支撑,这就需要对供应链网络中的各类资源进行合理整合。本文在分析不同场景下顾客需求偏好的基础上,重点探讨了面向无人零售终端资源整合中的供应链成员筛选机理,有针对性地提出了关键因素的挖掘和分类方法。在此基础上,构建了对应的整合优化模型和求解算法,并通过算例验证了方法和算法的可行性、有效性与可操作性。
