Online-based participatory design: A Case Study of Developing International Standards During a Pandemic

Standards are essential instruments to ensure the safety, efficiency and quality of products, services, systems, processes, and environments. In pre-pandemic times, standard development process used to happen through in-person consultation and meetings, however, the COVID-19 pandemic disrupted the whole routine. A team of technical experts from the National Standards Authority of Ireland trialled an online-based participatory design process to support the review and development of a standard through stakeholder engagement. This article introduces the experience of developing a new standard by leveraging on emerging digital technologies, through stakeholder participation. This research offers a framework, outlining the steps undertaken during the process, to support future online-based standard development processes in co-operation with stakeholders, by respecting cultures, backgrounds, skills, and experiences

Mathematical Modeling of a Nickel-Cadmium Cell: Proton Diffusion in the Nickel Electrode

In this paper we present a mathematical model of a sealed nickel-cadmium cell that includes proton diffusion and ohmic drop through the active material in the nickel electrode. The model is used to calculate sensitivity coefficients for various parameters in the model. These calculations show that the discharge voltage of the cell is affected mostly by the kinetics of the nickel reaction. Toward the end of discharge, proton diffusion also becomes important, because the proton diffusion process affects the active material utilization significantly. During charge, the cell voltage is mainly affected by the kinetics of the nickel reaction until the oxygen evolution reaction begins, after which time the kinetics of the oxygen evolution has the largest effect. The oxygen evolution reaction is also the most influencing factor on the actual charge uptake of the cell by the end of a charge operation (charge efficiency). Compared to the rates of reaction and proton diffusion, the ohmic drop in the active material of the nickel electrode and the mass transport and ohmic drop in the electrolyte have negligible effect on the behavior of the cell studied here

The overlooked cohort? – Improving the taught postgraduate student experience in higher education

Taught postgraduate students in the UK have a limited timeframe for study, with most full-time courses requiring intense scholarship, typically over a 12-month period. Many of these students face challenges and concerns with the transition from undergraduate to taught postgraduate study as they adapt to a new learning environment with higher academic expectations. In this paper, we discuss the results of a new experience survey, designed to capture a holistic view of taught postgraduate student feedback beyond traditional academic content and to also capture self-reported challenges experienced during their studies. This article also describes the development of a new collaborative support programme in response to student feedback. The programme has been designed to offer a cohesive package of workshop sessions around academic skills, well-being, support and career development. The importance of providing a targeted support framework for this specific and often overlooked cohort within the HE sector is discussed

Poverty from fetal life onward and child brain morphology

Poverty is a risk factor for impaired child development, an association possibly mediated by brain morphology. Previous studies lacked prospective poverty assessments during pregnancy and did not stratify by majority/minority status. We investigated the association of household poverty from fetal life forward with brain morphological differences at age 10 years, in 2166 mother–child dyads. Overall, the results showed no associations between any poverty exposure early in life and brain volumes. However, there was the evidence of timing effects: children exposed to poverty in utero had smaller amygdala volumes (B =  − 0.18, 95%CI − 0.30; − 0.07, p(FDR-adjusted) = 0.009). There were also differences in associations by majority/minority status (cerebral white matter: p for interaction = 0.04). Dutch children exposed to childhood poverty showed smaller cerebral white matter volumes than their control (B =  − 0.26, 95%CI − 0.45; − 0.06, p(FDR-adjusted) = 0.035). This association was not observed in the minority population (B =  − 0.05, 95%CI − 0.23; 0.12, p(FDR-adjusted) = 0.542). The smaller cerebral white matter volume mediated the association between childhood poverty and poorer school performance in Dutch children. Our findings point to the importance of poverty exposure in the fetal period and suggest different mechanisms and vulnerabilities across majority/minority groups

Genomics reveals historic and contemporary transmission dynamics of a bacterial disease among wildlife and livestock

Whole-genome sequencing has provided fundamental insights into infectious disease epidemiology, but has rarely been used for examining transmission dynamics of a bacterial pathogen in wildlife. In the Greater Yellowstone Ecosystem (GYE), outbreaks of brucellosis have increased in cattle along with rising seroprevalence in elk. Here we use a genomic approach to examine Brucella abortus evolution, cross-species transmission and spatial spread in the GYE. We find that brucellosis was introduced into wildlife in this region at least five times. The diffusion rate varies among Brucella lineages (∼3 to 8 km per year) and over time. We also estimate 12 host transitions from bison to elk, and 5 from elk to bison. Our results support the notion that free-ranging elk are currently a self-sustaining brucellosis reservoir and the source of livestock infections, and that control measures in bison are unlikely to affect the dynamics of unrelated strains circulating in nearby elk populations
