Collision detection and proximity warning systems for mobile mining equipment: A human factors exploration

The relatively high number of collisions between mining vehicles is the primary reason why collision detection and proximity warning systems are being increasingly introduced in this domain. This work presents a series of studies undertaken in underground mining where a prototype proximity warning system has recently been introduced. These studies encompassed a review of the system constraints (detection distances), an ergonomic audit of the system interface, Cognitive Tasks Analyses and other structured interview methods, a naturalistic field study, and a human factors risk assessment. All combined, the studies reviewed, from a user-centred perspective, the effectiveness of a system being trialled. Preliminarily results emerging to date and provisional recommendations for future system development or additional research are briefly outlined in this paper

Knowledge elicitation solutions for improving performance and efficiency

Despite advances in mechanisation and automation processes, mining remains a people intensive industry, a large proportion of whom are responsible for operating and maintaining mining equipment under conditions that challenge even the most experienced people. Mining techniques, equipment designs and the work environment are constantly evolving and changing, imposing new demands on the technical competence of workers. With the trend towards global mining companies and ease of international travel, the workforce of the future may well encompass social and cultural changes that need to be addressed. The system of work rosters used by mine sites adds a further element of change to the situation, all of which contribute to the potential for unwanted events during normal operation

INSTEP SOCCER KICK TECHNIQUE AND PERFORMANCE THROUGH AN ANALYSIS OF MOVEMENT VARlABILlN

The purpose of this study was to investigate the structure of movement variability (MV) for hit and missed instep kicks using the uncontrolled manifold (UCM) analysis. University soccer players (n=1 1 ) performed a maximal instep kick at a target 11 metres (m) away. Hit and missed kicks were analysed using the UCM method. Dependent measures for UCM analysis were UCM variability measures and strength of synergy across six performance variables. Clear differences were noted between hit and missed kicks based on the UCM analysis. The UCM analysis provided a powerful tool for showing clear differences between hit and missed kicks and suggest that accurate kicking performance could be dependent on the structure of MV within the human motor system

Leveraging the Federal Government’s Buying Power to Mitigate Climate Change

As global temperatures continue to rise, this brief article focuses on the evolution of sustainable public procurement (primarily in the United States federal or central government marketplace). Among other things, the article introduces expanding efforts by the National Contract Management Association (NCMA) and its community of practice (COP) to raise awareness of the procurement profession\u27s and community\u27s role in adapting to and mitigating climate change, support knowledge sharing about existing work in this area, provide resources and training to contracting professionals, and integrate sustainability into contracting professional standards. Ultimately, what procurement officials buy, how they buy, and who they buy from can drive large shifts in the behavior of industry and consumers. The article asserts that the federal acquisition community needs to rapidly learn, embrace, and champion sustainable procurement practices. At the same time, nothing in the Federal Acquisition Regulation (FAR) prohibits the acquisition community from learning, thinking about, experimenting with, and sharing experiences; nor does it impede acquisition professionals from integrating sustainability considerations into requirements generation, acquisition planning, solicitation development, incentive design, contract negotiation, and contract management

Watch out for the hazard! Blurring peripheral vision facilitates hazard perception in driving

The objectives of this paper were to directly examine the roles of central and peripheral vision in hazard perception and to test whether perceptual training can enhance hazard perception. We also examined putative cortical mechanisms underpinning any effect of perceptual training on performance. To address these objectives, we used the gaze-contingent display paradigm to selectively present information to central and peripheral parts of the visual field. In Experiment 1, we compared hazard perception abilities of experienced and inexperienced drivers while watching video clips in three different viewing conditions (full vision; clear central and blurred peripheral vision; blurred central and clear peripheral vision). Participants’ visual search behaviour and cortical activity were simultaneously recorded. In Experiment 2, we determined whether training with clear central and blurred peripheral vision could improve hazard perception among non-licensed drivers. Results demonstrated that (i) information from central vision is more important than information from peripheral vision in identifying hazard situations, for screen-based hazard perception tests, (ii) clear central and blurred peripheral vision viewing helps the alignment of line-of-gaze and attention, (iii) training with clear central and blurred peripheral vision can improve screen-based hazard perception. The findings have important implications for road safety and provide a new training paradigm to improve hazard perception

Patient and provider experiences with relationship, information, and management continuity

From 2003 to 2014, the Health Quality Council of Alberta (HQCA) monitored patient experiences with healthcare services through a biennial Satisfaction and Experience with Healthcare Services (SEHCS) survey. The findings consistently showed a direct link between coordination of care, an aspect of continuity of care, and healthcare outcomes. Specifically, it showed that better coordination is linked to positive outcomes; the reverse is also true. Given the critical role continuity of care plays in the healthcare system, the HQCA conducted in-depth interviews, interactive feedback sessions and focus groups with patients and providers to explore factors that influence both seamless and fragmented patient journeys. Continuity of care refers to “the degree to which a series of discrete healthcare events is experienced as coherent and connected and consistent with the patient’s healthcare needs and personal context”. Reviews of international literature have identified three major subtypes of continuity across healthcare settings: relationship, information, and management continuity. This study showed that from the patient perspective, relationship continuity is most valued and is foundational for experiencing information and management continuity. A trusting, patient-centred, and respectful relationship with a primary healthcare provider is central to this. From the provider perspective, information continuity is most important. Primary care providers get frustrated if information is withheld or delayed, and if other providers change treatment plans or medications. Patients highly value timely access to their own information. They also value having enough time during an appointment with a family doctor who listens and communicates effectively. Both patients and providers value and benefit from management continuity, which was described by many as a partnership or shared responsibility for managing and coordinating healthcare services. Future conversations about health system design should focus on how all providers and services can work together, and engage patients, to co-design a system that is built around patient-centred relationships
