Current approaches to the assessment of graphic design in a higher education context

This article provides an overview of the current trends in assessment practice within the field of graphic design. The demands placed on educators to apply sound assessment practice for Higher Education subjects is as intense in the field of graphic design as in any other. Forcing the assessment of creative visual work into existing assessment methodologies is incongruous and is often, for good reason, met with resistance from lecturers in this field. Practical art and design modules tend to fall outside of the recognised assessment methodologies as the type of skills and thinking that students must evidence are difficult to define. Lecturers, in order to encouraging creativity, prefer to leave outcomes open ended in order to accommodate the unexpected and unique solutions that students are encouraged to achieve. This and the atypical assessment approaches taken in design subjects make justifying assessment practice to the various role players challenging. In this article current trends that make assessment more transparent, encourage deep learning and give the opportunity to assess not only the final artefact, but the creative process and the development of the learner as a design practitioner, are identified. These approaches can provide lecturers with the basis for building sound assessment structures and empowering them to clearly justify their assessment practice.http://onlinelibrary.wiley.com/journal/10.1111/(ISSN)1476-8070hb2016Humanities Educatio

Nevertheless, there is evidence of important differences between these two disorders. Some authors have conceptualized the disorders as lying on an OCD spectrum of conditions. Methods Two hundred and seventy eight OCD patients (n = 278: 148 male; 130 female) and 54 TTM patients (n = 54; 5 male; 49 female) of all ages were interviewed. Female patients were compared on select demographic and clinical variables, including comorbid axis I and II disorders, and temperament/character profiles. Results OCD patients reported significantly more lifetime disability, but fewer TTM patients reported response to treatment. OCD patients reported higher comorbidity, more harm avoidance and less novelty seeking, more maladaptive beliefs, and more sexual abuse. OCD and TTM symptoms were equally likely to worsen during menstruation, but OCD onset or worsening was more likely associated with pregnancy/puerperium. Conclusions These findings support previous work demonstrating significant differences between OCD and TTM. The classification of TTM as an impulse control disorder is also problematic, and TTM may have more in common with conditions characterized by stereotypical self-injurious symptoms, such as skin-picking. Differences between OCD and TTM may reflect differences in underlying psychobiology, and may necessitate contrasting treatment approaches.Published versio

Postural variations in Cardio Stress Index scores

Numerous factors influence heart rate variability, including age, exercise and posture. The Cardio Stress Index (CSI) is a transformed measure of heart rate variability that is determined via a miniature digital multi-channel electrocardiogram system. Although the CSI and heart rate variability are reportedly analogous, little is known about how the two concepts compare in peer-reviewed research. The aim of this study was to examine the differences between CSI and heart rate as measured on a mini- electrocardiogram device when subjects were sitting upright and when they were lying down (in supine position). This is a case-series study with no intervention or follow-up. Sitting and supine CSI and heart rate readings were compared in a random sample of 55 women volunteers recruited through advertising in Pretoria, South Africa. The mean age of the sample was 25.01 years (SD = 7.56). After completing a biographical questionnaire, subjects’ CSI and heart rates were evaluated using a digital medical device, the ViportTM. The combined CSI for the group was elevated above the normative value of 20% (31.00%; SD = 14.03). The seated, supine and combined CSI all differed significantly from one another (p<0.05) and the CSI was significantly correlated with heart rate (p=0.41). In conclusion, the CSI readings, like heart rate variability measurements taken in different postures, cannot be used interchangeably in clinical practice or in research. The CSI appears to mirror existing research evidence on heart rate variability and posture.http://www.ajol.info/journal_index.php?jid=153&ab=ajpher

Initial assessment of well-being in South African armed services personnel

As professionals in law enforcement and defence (armed services) function under high pressure, the maintenance of overall health should be emphasized and closely monitored in training facilities. The aim of this research was to assess current health status and risk factors of the members of three armed service training facilities. This represents the first step in an integrated approach toward health maintenance in this important sector. The sample consisted of 323 members from three different armed service training facilities in South Africa. The subjects completed a questionnaire on health history and coping with stress. Heart health, body composition, general fitness and co-ordination were then examined. The mean age of the sample was 38.08 years (SD=8.81). The mean blood pressure readings were pre-hypertensive (Systolic 127.4mmHg, SD=16.67; Diastolic 82.74mmHg, SD=10.94) and the mean BMI was in the overweight category (27.97kg/m2, SD=8.81). The percentage (more than 40 %) of subjects that require physical fitness intervention reflects an urgent need for effective implementation of wellness programmes in this sector.http://www.ajol.info/journal_index.php?jid=153&ab=ajpher

The bii4africa dataset of faunal and floral population intactness estimates across Africa’s major land uses

Sub-Saharan Africa is under-represented in global biodiversity datasets, particularly regarding the impact of land use on species’ population abundances. Drawing on recent advances in expert elicitation to ensure data consistency, 200 experts were convened using a modified-Delphi process to estimate ‘intactness scores’: the remaining proportion of an ‘intact’ reference population of a species group in a particular land use, on a scale from 0 (no remaining individuals) to 1 (same abundance as the reference) and, in rare cases, to 2 (populations that thrive in human-modified landscapes). The resulting bii4africa dataset contains intactness scores representing terrestrial vertebrates (tetrapods: ±5,400 amphibians, reptiles, birds, mammals) and vascular plants (±45,000 forbs, graminoids, trees, shrubs) in sub-Saharan Africa across the region’s major land uses (urban, cropland, rangeland, plantation, protected, etc.) and intensities (e.g., large-scale vs smallholder cropland). This dataset was co-produced as part of the Biodiversity Intactness Index for Africa Project. Additional uses include assessing ecosystem condition; rectifying geographic/ taxonomic biases in global biodiversity indicators and maps; and informing the Red List of Ecosystems
