Homotopy theory of looped polyhedral products
No full textThis thesis studies the pointed loop space of spaces known as polyhedral products and gives loop space decompositions in various cases as a product of well-studied spaces. It is a research paper thesis which contains the following papers:[1] L. Stanton, Loop space decompositions of moment-angle complexes associated to flagcomplexes, Q. J. Math. 75 (2024), no. 2, 457–477,[2] L. Stanton, Loop space decompositions of moment-angle complexes associated to twodimensional simplicial complexes, (2024), to appear in Proceedings of theEdinburgh Mathematical Society, https://arxiv.org/abs/2407.10781,[3] L. Stanton and S. Theriault., Polyhedral products associated to pseudomanifolds, Int.Math. Res. Not. 2025 (2025), rnaf164.In [1], we show that the loop space of a moment-angle complex associated to the -skeleton of a flag complex decomposes as a product of spheres and loops on spheres up to homotopy.In [2], we show that the loop space of a moment-angle complex associated to a -dimensional simplicial complex decomposes as a product of spheres, loops on spheres and well-studied torsion spaces up to homotopy.In [3], we study the homotopy theory of polyhedral products associated to a combinatorial generalisation of manifolds known as a pseudomanifold. We use this to show that the loop space of a moment-angle manifold associated to a connected, orientable surface, or a triangulation of decomposes as a product of spheres and loops on spheres up to homotopy
Comparing verbal media for alarm handling: Speech versus textual displays
No full textThe rise of computers in command and control domains has meant that control operations can be performed via desk-based visual display terminals. This trend has also produced the potential to display information to operators in a variety of formats. Of particular interest has been the use of text-based displays for alarm presentation. There are possible limitations to the use of text for alarm presentation, not least of which is the need for a dedicated alarms display screen (or, at least, a display page). Given the capability of computers to synthesize speech, it is possible that speech-based alarms could generate the same information as text-based displays without the need for dedicated screen space. In this paper an experimental comparison of speech-based and text-based displays for presentation of alarms is reported. The findings show that speech leads to longer response times than text displays, but that it has minimal effect on the efficacy of fault handling. The results are discussed within the alarm initiated activities framework and implications for alarm system design are outlined
Alarm initiated activities: Matching formats to tasks
No full textThis paper addresses the selection of visual alarm formats for different 'alarm initiated activities'. The activities under examination were alarm handling tasks. Seven such tasks have been identified, namely: observe, accept, analyse, investigate, correct, monitor and reset. One of the most important stages is the initial analysis of the alarm information as this determines the subsequent manner in which the information is processed. It was hypothesised that the format in which the information is presented will determine the success of the alarm handling task, hence the proposal to match formats to tasks. The findings suggest that text-based formats are best suited to tasks requiring time-based reasoning, mimic formats are best suited to tasks requiring spatial location and annunciator formats are best suited to tasks requiring recognition of spatial patterns. The importance of considering both reaction time and accuracy of response in consideration of task match was also noted. In summary, it is suggested that care needs to be taken to determine the appropriateness of the medium for any given task and the demands it places on the human operator
Is utility in the mind of the beholder? A review of ergonomics methods
No full textThis paper reviews the use of ergonomics methods in the context of usability of consumer products. A review of the literature indicated that there is upward of 60 methods available to the ergonomist. The results of the survey indicated that questionnaires, interviews and observation are the most frequently reported methods used. Ease of use of the methods was dependent upon type of method used, presence of software support and type of training received. Strong links were found between questionnaires and interviews as a combined approach, as well as with HTA and observation. However, a questionnaire survey of professional ergonomists found that none of the respondents had any documented evidence of the reliability and validity of the methods they were using. A study of training people to use ergonomics' methods indicated the different requirements of the approaches, in terms of training time, application time and subjective preferences. An important goal for future research is to establish the reliability and validity of ergonomics methods
Behavioural compensation by drivers of a simulator when using a vision enhancement system
No full textTechnological progress is suggesting dramatic changes to the tasks of the driver, with the general aim of making driving environment safer. Before any of these technologies are implemented, empirical research is required to establish if these devices do, in fact, bring about the anticipated improvements. Initially, at least, simulated driving environments offer a means of conducting this research. The study reported here concentrates on the application of a vision enhancement (VE) system within the risk homeostasis paradigm. It was anticipated, in line with risk homeostasis theory, that drivers would compensate for the reduction in risk by increasing speed. The results support the hypothesis although, after a simulated failure of the VE system, drivers did reduce their speed due to reduced confidence in the reliability of the system

Driving automation: Learning from aviation about design philosophies
No full textFull vehicle automation is predicted to be on British roads by 2030 (Walker et al., 2001). However, experience in aviation gives us some cause for concern for the 'drive-by-wire' car (Stanton and Marsden, 1996). Two different philosophies have emerged in aviation for dealing with the human factor: hard vs. soft automation, depending on whether the computer or the pilot has ultimate authority (Hughes and Dornheim, 1995). This paper speculates whether hard or soft automation provides the best solution for road vehicles, and considers an alternative design philosophy in vehicles of the future based on coordination and cooperation
Byrne Stanton letter to A.B. Stanson, January 16, 1904
No full textLetter from Byrne Stanton of Cincinnati, son of Dr. Benjamin Stanton of Salem, Ohio, to A. B. Stanson at the Periodical Division of the Library of Congress, in response to Stanson's recent inquiry concerning Lundy's anti-slavery periodicals. The letter details Lundy's publishing history and involvement in the abolitionist movement, leading up to his publication of the Genius of Universal Emancipation in 1821. A. B. Stanson, it seems, has been interested in acquiring a complete collection of the papers for the Library of Congress. Benjamin Lundy (1789-1839) was a prominent Quaker abolitionist best known for his development of abolitionist periodicals. His Genius of Universal Emancipation was first published in 1821 from his home in Mt. Pleasant, Ohio, and enjoyed a wide circulation across the antebellum United States. In the 1820s, the young William Lloyd Garrison came to work for The Genius. Benjamin Lundy traveled widely seeking subscriptions to The Genius, giving talks about the anti-slavery movement, and observing and documenting the conditions of enslaved people across the Americas. He was also involved in the establishment of freed slave colonies in Mexico
Rosemary Stanton on ethical eating
No full textThere once was a time when what to have for dinner was a simple choice, decided by cost and availability. But no longer. In a world with increasingly diminishing resources, eating is now complicated by a range of social, environmental and agricultural concerns. Choosing our food is getting confusing, but here, talking at UTS in Sydney, nutritionist Rosemary Stanton gives some practical advice on ethical eating. She is joined by researcher Dana Cordell, who\u27s been studying the environmental implications of the decreasing supply of phosperous in Australia and the world. The event is chaired by Prof. Stuart White from UTS\u27s Institute for Sustainable Futures, and presented as part of the UTSpeaks Series.
Professor Stuart White has been researching sustainability for the last twenty years. In 1998 he was a member of the NSW Task Force on Water Conservation.
Dr Rosemary Stanton is a nutritionist and author of numerous books on the topic of healthy eating. She is also a member of the NSW Health Department\u27s Food Advisory Committee.
Dana Cordell is a senior researcher and doctoral student at the Institute for Sustainable Futures (ISF) at the University of Technology, Sydney. She is also co-founder of the Global Phosphorus Research Initiative.
