线状需求下两阶段设施选址问题     

王紫萌  周建勤 《上海海事大学学报》2020,41(3):60-65

鉴于大型交通线路建设项目的物资需求随时间变化(在初期阶段需求较低;在后续阶段项目全面展开,需求显著上升),本文采用线积分对沿线连续分布的线状物资需求进行刻画,构建两阶段设施选址模型,第一阶段进行部分设施的选址,第二阶段对剩余设施选址,以实现系统总成本最低的目标。针对模型特点,设计基于Voronoi图的两阶段交替定位-分配(alternative location-allocation,ALA)算法进行求解,并进行实例分析,比较两阶段模型与传统模型的异同。研究表明,将两阶段设施选址模型应用于交通线路建设项目多物流节点选址,能节约运营成本,并缓解初期资金压力。  相似文献

The “Free Press” of Unionized Journalists and Students     

Errol Salamon 《Journalism Practice》2018,12(5):565-584

This paper outlines a history of the union organizing of the American Newspaper Guild at Thomson Newspapers’ Peterborough Examiner in Canada from 1968 to 1969. It examines the communication tools that union members used to facilitate this labor organizing and “bite back” at the profitable Thomson chain. Peterborough newsworkers went on strike from November 1968 to April 1969 over union recognition. During the strike, the union members built an unprecedented alliance with Ontario university students, collaboratively launching a strike newspaper called the Peterborough Free Press. Expanding on the concept of temporary labor convergence, this paper considers how strike newspapers can be seen as a form of alternative journalism that newsworkers use as a campaigning tool to communicate their struggles to the public and put pressure on news corporations to bargain with them. This case study is situated in the local institutional contexts of labor relations at the Peterborough Examiner and the news industry in Peterborough, where Thomson Newspapers had a media monopoly. It is based on labor standpoint and signal juncture analyses of union archival documents and newspaper content. The research ultimately suggests that newsworkers should not only focus on communication tools but also build bridges with community members.  相似文献

Wartime imaginings of an archipelagic community: Fajar Asia and the quest for peninsula Malayan and Indonesian unity     

Sandra Khor Manickam 《Inter-Asia Cultural Studies》2017,18(3):347-363

During a brief period in the Japanese occupation of Southeast Asia, Malaya, including Singapore, was administratively placed with Sumatra under Japan’s 25th Army. From 28 March 1942 to April 1943, the two territories that had been separated by British and Dutch colonial rule since the mid-nineteenth century were considered one territory. This article explores how Malay intellectuals, through articles written in the magazine Fajar Asia, took advantage of this unprecedented opportunity to strive for a Malaya-Sumatra and Malaya-Indonesia community. This article will analyse the various wartime imaginings of a joint archipelagic community within the pages of Fajar Asia and highlight tensions within this project which resulted in an impasse as to how such a unity should or could be achieved.  相似文献   

试析晚清文化传播的两种模式     

方国武 《安徽教育学院学报》2006,24(1):20-23,96

晚清的文化传播呈现出两种不同模式。精英化的文化传播模式极力展现有关国家民族的政治理念等宏大叙述,体现出传播主体精英化的身份特征和价值立场,在特定时期有其历史意义,也有自身缺陷。大众化的文化传播模式突出普通民众的审美情趣和心理体验,体现了晚清民间知识分子的价值取向,有着精英文化传播模式不可替代的社会意义。  相似文献
