Integration | Innovation | Inclusion: Values,Variables and the Design of Human Environments

Complexity, complication, contradiction, consumption, confusion, delusion, depression. Opportunity, inspiration, ingenuity, compassion, wisdom. Our world is perplexing, our times are fast moving, and our choices are many. To find an appropriate path is a daunting yet vital challenge that confronts us as individuals, as communities, and as a civilization. How sustainable is our world? How reasonable are our behaviors? The present article is a collection of thoughts on a series of intertwined issues related to the contemporary world, its environmental dimensions, and their present-day problems. The goal is to survey the landscape through a lens of Environmental Design, to provide some perspectives, to raise some questions, and to explore systems, beliefs, and values informing and influencing actions. It is important to consider how people's belief systems influence, inform, and shape actions. This holds true in realms political, spiritual, and cultural. It also proves relevant in the ways in which we imagine, design, develop, and construct our buildings, cities, spaces, and places.

Appropriate solutions to some of our most daunting problems will arise through the concerted efforts, open dialogue, and collective wisdom of the wide array of stakeholders, professionals, politicians, decision makers, and citizens (both engaged and disenfranchised) who have the will and wherewithal to make a difference and to make the world safer, healthier, and better. It seems vital for us to critically examine, and question, our belief systems and their connections to the ways we define, refine, and realize progress. Architecture and Environmental Design, in both a philosophical and a practical sense, reflect as well as form greater aspirations, directions, and events of our times.     

Human factors in support of a successful railway: a review

One of the critical infrastructure components in most economies across the world is the rail network. In different nations rail is responsible for ensuring that there is not complete gridlock on the roads in commuter hours, and for moving both people and freight for long distances in an as efficient manner as possible. This critical role, a number of high profile accidents and proposals for new network control philosophies and systems have led to a great upsurge in human factors rail research and applications in the past few years. This paper provides a retrospective on rail human factors research covering driving, signalling and control, maintenance, incident reporting systems, passengers and the public, planning and technical systems change. This research foundation, and also current major rail human factors programmes, are placed in the context of technology, investment, competition, cultural and safety requirements and constraints. The paper concludes with an examination of where rail human factors should and will be going into the future. Rail human factors research has grown rapidly in both quantity and quality of output over the past few years. There was an early base of work at a few institutions carried out over the 1960 s and 1970 s, followed by a lull in the 1980 s and early 1990 s. The continual influences of safety concerns, new technical system opportunities, reorganisation of the business, needs to increase effective, reliable and safe use of capacity, and increased society, media and government interest have now accelerated rail human factors research programmes in several countries. In this paper we review the literature on rail human factors research, covering driving, signalling and control, maintenance, reporting systems, passenger interests, planning and technical systems change. Current major rail human factors programmes are summarised and future research needs proposed. It is asserted that general human factors models and methods are being re-assessed, and new ones developed, to meet the requirements of the railways. This paper has, with the agreement of all editors concerned, been published in substantially similar form as: Wilson J. R. and Norris B. J., 2005, Rail human factors: past, present and future. Applied Ergonomics, 36, 6, 649–660.

Policy Matters Now and in the Future: Net Neutrality, Corporate Data Mining, and Government Surveillance

In this article, I will detail three key policy issues that have a profound effect on the future of the World Wide Web and Internet-based communications: net neutrality, corporate data mining, and government surveillance. Focusing on policy issues in the U.S., I will describe not only current practices and cases, but future possibilities for writers and teachers of writing. I will draw from work in composition, interdisciplinary studies on privacy, information sharing, and surveillance on the Internet, analyses of applicable policies and laws, and the advocacy efforts by organizations. Issues I will examine include the importance of and threats to net neutrality; how data mining and (so-called) privacy agreements currently work, specifically at social networking sites often used in writing classrooms; and how government and institutional surveillance is far more prevalent than many realize. I will close with recommendations for what writing instructors (and students) can do to try to craft a different future, one where writers and the visual, verbal, aural writing they read and produce online will not be collected, scrutinized, and controlled (or, realistically, at least not as much).

The CONTRAM Dynamic Traffic Assignment Model

CONTRAM is a computer model of time-varying traffic in road networks, which takes as input the network definition and time-varying demand for travel between a set of origin and destination zones, and outputs the resulting network flows, routes and travel times. It combines a macroscopic time-sliced traffic model with disaggregate dynamic assignment of traffic, so is intermediate between macroscopic equilibrium and microscopic models. The paper details the methods used, including time-dependent queuing which plays a central role, and the treatment of network definition, user classes, road capacities, signals and coordination, vehicle emissions, Intelligent Transport Systems and research lines.     

新闻推荐算法可信评价研究

随着AI、5G、AR/VR等新技术的快速发展,内容类应用如电子商务、社交网络、短视频等层出不穷,导致信息过载问题日益严重。人工智能技术的发展推动了智能算法的爆炸式运用,作为智能算法的一种,推荐算法在大数据、应用场景和计算力的推动下,通过信息过滤技术,为用户提供适应兴趣及行为的个性化及高质量的推荐服务,逐步提高了用户的使用体验、内容分发效率,在一定程度上缓解了信息过载的问题。但推荐算法的潜在偏见、黑盒化特性及内容分发方式也逐渐带来了决策结果不公平性、不可解释性,信息茧房、侵犯用户隐私等安全挑战。如何提高推荐算法的可解释性、公平性、可信程度等越来越受到国内外政府监管部门、产业及学术界的重点关注,推荐系统和推荐算法也由此从发展期进入管制期。为此,本文针对新闻推荐领域,分析推荐算法的稿件画像、用户画像、推荐推送、反馈干预和人工复审等关键要素,围绕推荐算法生态的参与者,如内容生产者、受众、算法模型、新闻平台,从公平性、可解释性和抗抵赖性三个方面提出了一种新闻推荐算法可信评价体系,并进行定量或定性分析。公平性、可解释性和抗抵赖性是正相关关系,当公平性和抗抵赖性越强、可解释程度越高,新闻推荐算法的可信度越高。希望弥补新闻推荐算法领域的可信研究的空白,建立可信推荐算法生态,加速安全推荐系统的建立和推广,同时为智能算法可信研究提供参考,为智能算法的监管和治理提供思路。
