Significance of the dimensional view for visualizing relevant aspects of a production system in a co-operative planning process

Pictorial visualization is expected to facilitate communication between industrial professionals when planning working environments and production systems. This hypothesis was investigated by studying how 24 participants including managers, supervisors, machine operators, and occupational health and safety officials, judged three types of computer animated visualization varying in dimensional view (scale and scope of a production line):shop floor view/survey of shop floor; production unit view/semi-survey of production unit; and workplace view/close-up of workplace, in relation to a set of planning issues. The participants participated in a controlled 2-day planning workshop, redesigning a fictitious manufacturing process by means of computer graphics, and then responded to a questionnaire. It can be concluded that shop floor view as well as production unit view are significant for survey planning issues, while all 3-dimensional views are significant for close-up planning issues. Analogously, all dimensional views are significant for technocentric planning issues, whereas only the workplace view is valuable for anthropocentric planning issues.     

Can participatory ergonomics become 'the way we do things in this firm'- The Scandinavian approach to participatory ergonomics

Under the label ‘participatory ergonomics’ the idea of establishing changes in working conditions through participatory approaches has been a central issue within ergonomics. Tools and procedures have been developed and demonstrated beneficial. But how this approach can be established as the way changes are made in firms have only had limited attention. In the Scandinavian countries legislation has, through mandatory joint working environment committees, tried to establish an organizational unit promoting direct participation. Several studies have showed that the intentions of the legislators are not automatically fulfilled, and they have reviled preconditions for more successful acheivement. This opens for many supplementary regulatory strategies to improve activities in firms, but one has been in focus: establishing formalized management systems within occupational health and safety. This strategy may be contrary to the general intentions in the laws. Some of the conditions which must be taken into consideration are discussed.     

Time,place, technology: Twitter as an information source in the Wisconsin labor protests

Recently, Twitter has become a prominent part of social protest movement communication. This study examines Twitter as a new kind of citizen journalism platform emerging at the aggregate in the context of such “crisis” situations by undertaking a case study of the use of Twitter in the 2011 Wisconsin labor protests. A corpus of more than 775,000 tweets tagged with #wiunion during the first 3 weeks of the protests provides the source of the analyses. Findings suggest that significant differences exist between users who tweet via mobile devices, and thus may be present at protests, and those who tweet from computers. Mobile users post fewer URLs overall; however, when they do, they are more likely to link to traditional news sources and to provide additional hashtags for context. Over time, all link-posting declines, as users become better able to convey first-hand information. Notably, results for most analyses significantly change when restricted to original tweets only, rather than including retweets.     

Cross-cutting exposure on social networking sites: The effects of SNS discussion disagreement on political participation

Drawing on a national probability survey, this study explores the relationship between discussion disagreement on social networking sites and political participation by focusing on the intervening effects of political discussion and news use. The results revealed that discussion disagreement on SNSs inhibits off- and online political participation, and this relationship is partially mediated by the frequency of SNS political discussion. Furthermore, the frequency of news-related activities on SNSs is found to moderate the mediating effect of political discussion. The implications are discussed.     

观赏性还是参与性——浅析新疆维吾尔木卡姆传承中心建设模式

由于新疆维吾尔木卡姆艺术入选联合国教科文组织"人类口头和非物质遗产代表作",近年来,木卡姆传承中心作为政府申报书中"保护计划"的承诺,在新疆由各地政府部门组织建设。通过调研已经建成的三个木卡姆传承中心,发现其建设模式普遍偏重观赏性。在分析木卡姆艺术的特色及传承背景后,指出木卡姆传承中心建设模式向重民众性和参与性转变是恰当和具有现实意义的观点。     

The propensity for employee participation by electrical and mechanical trades in the construction industry

Using the four input-output tables compiled in Turkey to date, the aim of this paper is to examine the construction sector's role in the Turkish economy and analyse its relationships with the other sectors of the national economy. Analysis results show that the share of construction in Gross National Product (GNP) and National Income (NI) tend to increase whereas the GNP share of manufacturing is relatively stable and that of services tend to increase after an abrupt decrease in 1985; backward linkage indicators and output multipliers, as well as forward linkage indicators and input multipliers of construction industry are stable; and finally, direct and total construction inputs from manufacturing show relative stability and those from services tend to increase in recent years. These findings point out the similarities between the Turkish construction industry and some advanced industrial countries (AICs) like Japan and Italy showing signs of growing ‘maturity’ of the Turkish economy.     

基于改进遗传算法的TMD阻尼器的优化布置

调谐质量阻尼器被广泛应用于高耸结构振动控制。为了提高阻尼器的减振效果,基于安全性要求,建立等效二次型性能指标;通过改进遗传算法,求得TMD阻尼器的最佳安装位置,从而提高TMD减振系统的减振效果。最后通过仿真实验验证优化的意义,并得出一些结论:对于塔筒结构减振控制,不仅要针对低阶振型进行控制,高阶振型的扭转振动也不容忽视。     

冒险游戏场的起源、实例与启示

游戏是儿童成长中不可或缺的部分,儿童友好城市的重要硬件措施是建设儿童游戏据点。冒险游戏场作为代表性场所,在治愈儿童心理问题、培养儿童责任感、激发儿童危机意识和自我保护技能等方面发挥了重要作用。冒险游戏场在国外已有70余年的实践历史,但我国对冒险游戏场的研究尚处于初级阶段,在实践方面仍属空白。本文从剖析冒险游戏场的起源与核心思想入手,重点围绕欧美和日本的发展背景,对其发展历史进行系统梳理,再深入解读"常设"和"非常设"的三个典型案例,总结出设计理念"自由化"、空间要素"自然化"、场所运营"专业化"三个关键启示,为我国儿童公共空间的研究提供借鉴和参考。
