Pedagogy for personal transformation: Faith development in the context of a Scottish Baptist College

This paper explores aspects of the personal transformation of students through theological education, (i) by proposing a theological interpretation based on the perspective of convictional theology; and (ii) by offering insights arising from Transactional Analysis on how students can be moved to a mature phase of life and faith development

Marion Island volcanism and glaciation

Sub-Antarctic Marion Island was the site of extensive volcanism as well as glaciation during both the Quaternary and the Holocene. Initial reconstructions suggested a link between deglaciation and the initiation of faulting which, in turn, facilitated lava eruptions during the interglacials. However, our reassessment of the faulting, volcanic rock, and palaeoglacier distribution indicate that these original interpretations were erroneous. Features thought to be due to faulting are shown to be erosional scarps and this significantly changes interpretations of former glacier distribution. Further, the loss of the former ice cap has revealed new information on former glaciers and their flow directions, thereby allowing reconstruction of palaeoglaciers. Our new reconstruction fits with information from invertebrate genetic mapping that suggest some lava outcrops were nunataks and, therefore, refuges during the Last Glacial period. The new findings of glacial landforms in areas previously covered by snow suggest there was a significant ice advance during the Little Ice Age. Although Holocene volcanic rocks overlie and mask much of the glacial evidence, it has been possible to develop a proposed new reconstruction for glaciation, which is presented together with some of the implications.The University of Northern British Columbia helped KH with some of the travel costs associated with undertaking this work.

Rock mass loss on a nunatak in Western Dronning Maud Land, Antarctica

This paper presents the first rock mass loss data for uncut clasts from continental Antarctica. A rock mass loss experiment using doleritic rock samples was conducted over a seven-year period, between 2008 and 2014, at the Vesleskarvet nunataks, Western Dronning Maud Land. The data show that approximately 10% of clasts suffered a mass loss that is an order of magnitude greater than the remaining 90% of clasts. Thus, the observed rock mass loss is suggested to occur in a series of events that are impossible to predict in terms of frequency and/or magnitude. However, extrapolating from the data obtained during the seven-year period indicates that rates of mass loss are slow and of the order of 1% per 100 years. Direct erosion by wind (including abrasion) as well as mechanical and chemical weathering are suggested to be responsible for rock mass loss. Rock properties, the weathering environment, and a lack of available moisture may be contributing factors to the slow rate of rock decay. This paper suggests that in this area of Antarctica, the slow rate of rock mass loss increases the longevity of existing periglacial landforms such as patterned ground and blockfields, but inhibits development of new patterned ground through the slow production of fines.The Department of Environmental Affairs and the National Research Foundation are gratefully acknowledged for logistical and financial support.

Spatial association of lemming burrows with landforms in the Swedish subarctic mountains : implications for periglacial feature stability

Burrowing mammals often have considerable geomorphological impacts, and their tunneling activities may decrease the stability of landforms. We document the spatial distribution of Norwegian lemming burrows in a subarctic alpine meadow to determine the preferred locations for burrow entrances and to examine the potential for burrowing to decrease the stability of periglacial landforms at the site. Burrow entrances were disproportionately common into the base and sides of landforms (.68% of burrows), probably reflecting the lower energetic cost of moving soil horizontally, rather than vertically, out of burrows. Most burrow entrances (.60%) were also located under large rocks, which probably improve burrow stability by providing a firm ceiling to the entrance. Field observations show that these burrows are relatively stable, as only 3% were associated with any signs of increased erosion or landform instability. Therefore, in contrast to some previous studies, and despite burrowing being concentrated on landforms, we suggest that these rodents have little direct impact on landform integrity at this site.South African National Research Foundation and the Swedish International Development Cooperation Agency.

SEAmester – South Africa’s first class afloat

publisher versionFrom Introduction: Marine science is a highly competitive environment. The need to improve the cohort of South African postgraduates, who would be recognised both nationally and internationally for their scientific excellence, is crucial. It is possible to attract students early on in their careers to this discipline via cutting-edge science, technology and unique field experiences. Through the engagement of students with real-life experiences such as SEAmester, universities supporting marine science postgraduate degree programmes can attract a sustainable throughput of numerically proficient students. By achieving a more quantitative and experienced input into our postgraduate degree programmes, we will, as a scientific community, greatly improve our long-term capabilities to accurately measure, model and predict the impacts of current climate change scenarios. The short-term goal is to attract and establish a cohort of proficient marine and atmospheric science graduates who will contribute to filling the capacity needs of South African marine science as a whole. The SEAmester programme, by involving researchers from across all the relevant disciplines and tertiary institutions, provides an opportunity to build a network of collaborative teaching within the marine field. In doing so, these researchers will foster and strengthen new and current collaborations between historically white and black universities (Figure 1). The long-term objective of SEAmester is to build critical mass within the marine sciences to ensure sustained growth of human capacity in marine science in South Africa – aligning closely with the current DST Research and Development strategies and the Operation Phakisa Oceans Economy initiative

EMOTICOM: A Neuropsychological Test Battery to Evaluate Emotion, Motivation, Impulsivity, and Social Cognition.

In mental health practice, both pharmacological and non-pharmacological treatments are aimed at improving neuropsychological symptoms, including cognitive and emotional impairments. However, at present there is no established neuropsychological test battery that comprehensively covers multiple affective domains relevant in a range of disorders. Our objective was to generate a standardized test battery, comprised of existing, adapted and novel tasks, to assess four core domains of affective cognition (emotion processing, motivation, impulsivity and social cognition) in order to facilitate and enhance treatment development and evaluation in a broad range of neuropsychiatric disorders. The battery was administered to 200 participants aged 18-50 years (50% female), 42 of whom were retested in order to assess reliability. An exploratory factor analysis identified 11 factors with eigenvalues greater than 1, which accounted for over 70% of the variance. Tasks showed moderate to excellent test-retest reliability and were not strongly correlated with demographic factors such as age or IQ. The EMOTICOM test battery is therefore a promising tool for the assessment of affective cognitive function in a range of contexts.This is the final version of the article.

Avelines's Hole: An Unexpected Twist in the Tale

Aveline’s Hole is the largest known Early Mesolithic cemetery in Britain, previously thought to have no evidence for subsequent burial activity. Thus, it came as some surprise when the results of a recent ancient human DNA study found that, of four individuals from the site yielding genomic data, two showed high levels of ancestry from Early Neolithic Aegean farmers. Radiocarbon dating confirmed that these two individuals were indeed British Early Neolithic in date, while the other two had the expected ‘Western Hunter-Gatherer’ ancestry genomic signatures, with the two groups separated in time by nearly five millennia. Moreover, the two Neolithic samples were both crania, while the two Mesolithic samples were long bones. Given the absence of Neolithic dates in the previous sizeable dating programme combined with the difficult history of the collection, i.e., the WWII bombing of its Bristol repository, this raised the question of whether the crania might in fact be from another site. As we show in this paper, a very strong case can be made that the crania do in fact originate from Aveline’s Hole. Additional radiocarbon dating (14 in total, including the above mentioned four) suggests that about half the cranial elements from the site fall within the Early Neolithic, though there is still no evidence for the deposition of post-cranial remains at this time, nor is there any burial evidence in the long intervening period between the Early Mesolithic and the Early Neolithic. Intriguingly, craniometric analyses of legacy data including three crania lost in the bombing suggest that one, Aveline’s Hole ‘A’, may be Upper Palaeolithicin date. As part of this re-investigation of the human remains from the site, we present new stable carbon and nitrogen isotope analyses that differ significantly from those originally reported for the Early Mesolithic, with the new results more in keeping with other isotopic data for this period. We also present new stable carbon and nitrogen isotope results on human remains from the nearby Early Mesolithic sites of Badger Hole and Greylake, and report new Early Mesolithic radiocarbon dates and isotopic data from Cannington Park Quarry. Clear isotopic differences between the Early Mesolithic and the Neolithic remains can be seen, but these are argued to relate primarily to shifts in the underlying ecological baselines, rather than to differences in types of foods consumed (with the caveat that terrestrial wild and domesticated foods will be isotopically similar). The genetic data are summarised, giving evidence not only of the ancestry of Mesolithic and Neolithic individuals from Aveline’s Hole, but also suggesting something of their physical appearance. The degree of population replacement now indicated by ancient DNA suggests that there was a substantial migration of farmers into Britain at the start of the Neolithic. This new information demonstrates the archaeological importance of Aveline's Hole for both the Mesolithic and Neolithic periods."Funding for nine of the new radiocarbon dates from Aveline’s Hole reported here was provided by NERC’s NRCF programme (NF/2016/2/16). The ancient DNA study was funded by the Wellcome Trust (100713/Z/12/Z), as were three new radiocarbon dates from Aveline’s Hole. The isotopic analysis of the Badger Hole human remains was funded as part of a NERC studentship (NE/K500987/1)."https://www.ubss.org.uk/resources/proceedings/vol28/UBSS_Proc_28_1_9-63.pd

South African research in the Southern Ocean: New opportunities but serious challenges

South Africa has a long track record in Southern Ocean and Antarctic research and has recently invested considerable funds in acquiring new infrastructure for ongoing support of this research. This infrastructure includes a new base at Marion Island and a purpose-built ice capable research vessel, which greatly expand research opportunities. Despite this investment, South Africa's standing as a participant in this critical field is threatened by confusion, lack of funding, lack of consultation and lack of transparency. The research endeavour is presently bedevilled by political manoeuvring among groups with divergent interests that too often have little to do with science, while past and present contributors of research are excluded from discussions that aim to formulate research strategy. This state of affairs is detrimental to the country's aims of developing a leadership role in climate change and Antarctic research and squanders both financial and human capital

Exploring South Africa’s southern frontier: A 20-year vision for polar research through the South African National Antarctic Programme

Antarctica, the sub-Antarctic islands and surrounding Southern Ocean are regarded as one of the planet’s last remaining wildernesses, ‘insulated from threat by [their] remoteness and protection under the Antarctic Treaty System’1 . Antarctica encompasses some of the coldest, windiest and driest habitats on earth. Within the Southern Ocean, sub-Antarctic islands are found between the Sub-Antarctic Front to the north and the Polar Front to the south. Lying in a transition zone between warmer subtropical and cooler Antarctic waters, these islands are important sentinels from which to study climate change.2 A growing body of evidence3,4 now suggests that climatically driven changes in the latitudinal boundaries of these two fronts define the islands’ short- and long-term atmospheric and oceanic circulation patterns. Consequently, sub-Antarctic islands and their associated terrestrial and marine ecosystems offer ideal natural laboratories for studying ecosystem response to change.5 For example, a recent study6 indicates that the shift in the geographical position of the oceanic fronts has disrupted inshore marine ecosystems, with a possible impact on top predators. Importantly, biotic responses are variable as indicated by different population trends of these top predators.7,8 When studied collectively, these variations in species’ demographic patterns point to complex spatial and temporal changes within the broader sub-Antarctic ecosystem, and invite further examination of the interplay between extrinsic and intrinsic drivers

Permafrost is warming at a global scale

Permafrost warming has the potential to amplify global climate change, because when frozen sediments thaw it unlocks soil organic carbon. Yet to date, no globally consistent assessment of permafrost temperature change has been compiled. Here we use a global data set of permafrost temperature time series from the Global Terrestrial Network for Permafrost to evaluate temperature change across permafrost regions for the period since the International Polar Year (2007-2009). During the reference decade between 2007 and 2016, ground temperature near the depth of zero annual amplitude in the continuous permafrost zone increased by 0.39 ± 0.15 °C. Over the same period, discontinuous permafrost warmed by 0.20 ± 0.10 °C. Permafrost in mountains warmed by 0.19 ± 0.05 °C and in Antarctica by 0.37 ± 0.10 °C. Globally, permafrost temperature increased by 0.29 ± 0.12 °C. The observed trend follows the Arctic amplification of air temperature increase in the Northern Hemisphere. In the discontinuous zone, however, ground warming occurred due to increased snow thickness while air temperature remained statistically unchanged
