Ontology-based e-assessment for accounting: Outcomes of a pilot study and future prospects

This article reports on a pilot of a novel ontology-based e-assessment system in accounting that draws on the potential of emerging semantic technologies to produce an online assessment environment capable of marking students' free-text answers to questions of a conceptual nature. It does this by matching their response with a "concept map" or "ontology" of domain knowledge expressed by subject specialists. The system used, OeLe, allows not only for marking, but also for feedback to individual students and teachers about student strengths and weaknesses, as well as to whole cohorts, thus providing both a formative and a summative assessment function. This article reports on the results of a "proof of concept" trial of OeLe, in which the system was implemented and evaluated outside its original development environment (an online course in education being used instead in an undergraduate course in financial accounting. It describes the potential affordances and demands of implementing ontology-based assessment in accounting, together with suggestions of what needs to be done if such approaches are to be more widely implemented. © 2013 Elsevier Ltd

A Method for Designing Conforming Folding Propellers

As the aviation vehicle design environment expands due to the in flux of new technologies, new methods of conceptual design and modeling are required in order to meet the customer's needs. In the case of distributed electric propulsion (DEP), the use of high-lift propellers upstream of the wing leading edge augments lift at low speeds enabling smaller wings with sufficient takeoff and landing performance. During cruise, however, these devices would normally contribute significant drag if left in a fixed or windmilling arrangement. Therefore, a design that stows the propeller blades is desirable. In this paper, we present a method for designing folding-blade configurations that conform to the nacelle surface when stowed. These folded designs maintain performance nearly identical to their straight, non-folding blade counterparts

Facilitators and barriers to co-research by people with dementia and academic researchers: findings from a qualitative study

Background Public and patient involvement (PPI) is now established in dementia research. Barriers and facilitators to engagement from family carers and people in early stages of dementia have been explored. However, specific barriers and facilitators to co‐research with people with dementia have not previously been investigated. Objective To discover the facilitators of, and barriers to, involving people with dementia as co‐researchers, from the perspectives of people with dementia, gatekeepers (family caregivers, ethics committee members, service providers) and researchers. Design Thematic analysis of data from individual interviews about the co‐research experience. Results Four themes emerged from interviews with 19 participants (five people with dementia): “getting one's head round it” (assumptions about research and dementia; different forms of language); practicalities (eg transport; accessibility of communication); “this feeling of safety” (perceptions of danger, protectiveness and opportunities for building trust); and motivations (“making a difference” and “keeping doing”). Conclusions Findings both replicate and extend previous knowledge on PPI in dementia. Cognitive capacity of potential co‐researchers with dementia is only a part of the picture, with attitudes and expectations of researchers, gatekeepers and people with dementia also forming barriers. Researcher education, adequate resourcing, and both creativity and flexibility are needed to support recruitment of co‐researchers with dementia and to enable meaningful co‐research

Trauma-Informed Supervision Experiences: A Preliminary Phenomenological Study

Trauma is pervasive in the clinical world of counseling. The current literature indicates adverse effects for survivors of a traumatic event and the counselors listening to the details of traumatic events, but there is a gap in research on the adverse effects trauma in counseling has on supervisors. This study aims to understand the lived experiences of supervisors who have dealt with traumatic experiences in clinical work through interviews with current supervisors of those who work with trauma. The results indicate trauma-informed supervision consists of trauma taking many forms, supervisors (and counselors) using the self in their work, supervisors knowing their stance, and developing a “third eye” as a new way of seeing

Towards the minimal amount of exercise for improving metabolic health: beneficial effects of reduced-exertion high-intensity interval training

High-intensity interval training (HIT) has been proposed as a time-efficient alternative to traditional cardiorespiratory exercise training, but is very fatiguing. In this study, we investigated the effects of a reduced-exertion HIT (REHIT) exercise intervention on insulin sensitivity and aerobic capacity. Twenty-nine healthy but sedentary young men and women were randomly assigned to the REHIT intervention (men, n = 7; women, n = 8) or a control group (men, n = 6; women, n = 8). Subjects assigned to the control groups maintained their normal sedentary lifestyle, whilst subjects in the training groups completed three exercise sessions per week for 6 weeks. The 10-min exercise sessions consisted of low-intensity cycling (60 W) and one (first session) or two (all other sessions) brief ‘all-out’ sprints (10 s in week 1, 15 s in weeks 2–3 and 20 s in the final 3 weeks). Aerobic capacity ( V˙O2peakV˙O2peak ) and the glucose and insulin response to a 75-g glucose load (OGTT) were determined before and 3 days after the exercise program. Despite relatively low ratings of perceived exertion (RPE 13 ± 1), insulin sensitivity significantly increased by 28% in the male training group following the REHIT intervention (P < 0.05). V˙O2peakV˙O2peak increased in the male training (+15%) and female training (+12%) groups (P < 0.01). In conclusion we show that a novel, feasible exercise intervention can improve metabolic health and aerobic capacity. REHIT may offer a genuinely time-efficient alternative to HIT and conventional cardiorespiratory exercise training for improving risk factors of T2D

Identification of Type 1 Diabetes-Associated DNA Methylation Variable Positions That Precede Disease Diagnosis

Monozygotic (MZ) twin pair discordance for childhood-onset Type 1 Diabetes (T1D) is similar to 50%, implicating roles for genetic and non-genetic factors in the aetiology of this complex autoimmune disease. Although significant progress has been made in elucidating the genetics of T1D in recent years, the non-genetic component has remained poorly defined. We hypothesized that epigenetic variation could underlie some of the non-genetic component of T1D aetiology and, thus, performed an epigenome-wide association study (EWAS) for this disease. We generated genome-wide DNA methylation profiles of purified CD14(+) monocytes (an immune effector cell type relevant to T1D pathogenesis) from 15 T1D-discordant MZ twin pairs. This identified 132 different CpG sites at which the direction of the intra-MZ pair DNA methylation difference significantly correlated with the diabetic state, i.e. T1D-associated methylation variable positions (T1D-MVPs). We confirmed these T1D-MVPs display statistically significant intra-MZ pair DNA methylation differences in the expected direction in an independent set of T1D-discordant MZ pairs (P = 0.035). Then, to establish the temporal origins of the T1D-MVPs, we generated two further genome-wide datasets and established that, when compared with controls, T1D-MVPs are enriched in singletons both before (P = 0.001) and at (P = 0.015) disease diagnosis, and also in singletons positive for diabetes-associated autoantibodies but disease-free even after 12 years follow-up (P = 0.0023). Combined, these results suggest that T1D-MVPs arise very early in the etiological process that leads to overt T1D. Our EWAS of T1D represents an important contribution toward understanding the etiological role of epigenetic variation in type 1 diabetes, and it is also the first systematic analysis of the temporal origins of disease-associated epigenetic variation for any human complex disease

A review of the benefits and drawbacks to virtual field guides in today’s Geoscience higher education environment

Virtual Field Guides are a way for educators to tackle the growing issue of funding pressures in areas of higher education, such as geography. Virtual Field Guides are however underutilised and can offer students a different way of learning. Virtual Field Guides have many benefits to students, such as being more inclusive, building student skills and confidence in a controlled environment pre fieldtrip and can increase engagement in the topic studied. There are also benefits to the educator, such as reduced cost, more efficient students on fieldwork tasks and the ability to tailor and update their field guides to suit their needs. However there are drawbacks in the challenge of creation and their outcome as educational standalone tools. This paper reviews the literature around the benefits and draw backs to the creation and incorporation of virtual field guides in geoscience education. © 2017, The Author(s)
