This article describes our qualitative research on the follow-up of 10 children, 5 years into recovery after cardiac surgery. The research was driven by a multi-disciplinary team of medical anthropologists, cardiologists, and an intensive care specialist and was based at the Red Cross War Memorial Children’s Hospital where they underwent surgeries. The research sought to answer two questions; first, could we successfully maintain contact with and follow up the children; the second – which will be answered in future papers – asked what life was like for them and their families during surgery and later recovery. The results are presented as a discussion on the themes that arose in our engagement and analysis and not as clinical evidence. These showed that elective surgery although significantly delayed was successful, and all children were followed up at their medical appointments. The researchers, however, were unable to establish follow-up with all families over the duration of the study. In the final round of interviews in the respondents’ homes, of 10 children, we remained in contact with seven. The discussion argues that effective communication and access to these children was often compromised by their coming from the poorer communities in the Cape Town metropolitan region, making them even more vulnerable during their recovery periods.
Enlist™ cotton contains the aad-12 and pat genes that confer resistance to 2,4-D and glufosinate, respectively. Thirty-three field trials were conducted focused on Enlist cotton injury from glufosinate as affected by cotton growth stage, application rate, and single or sequential applications. Maximum injury from a single application of typical 1X (542 g ae ha-1) and 2X use rates was 3 and 13%, respectively, regardless of growth stage. Injury from sequential applications of 1X or 2X rates was equivalent to single applications. Similar injury was observed with four commercial formulations of glufosinate. Cotton yield was never affected by glufosinate. This research demonstrates Enlist™ cotton has robust resistance to glufosinate at rates at least twice the typical use rate when applied once or twice at growth stages ranging from 2 to 12 leaves.
The exotic shrub red sesbania is an increasingly problematic weed in riparian and wetland ecosystems of California. Current control methods focus on manual removal, followed by herbicide application. Although this method effectively removes mature stands, the control is temporary because the presence of a large seed bank results in rapid germination and growth of new seedlings. We measured the density of seed banks beneath stands of varying densities and evaluated the potential of tarping and inundation for control of red sesbania seed banks. As expected, the abundance of viable red sesbania seeds in the soil was significantly greater beneath high-density stands than it was beneath low-density stands. Results for inundation and tarping experiments were mixed. Sustained inundation significantly decreased survivorship of germinated seeds compared with the control, as well as causing a statistically significant reduction in germination. Seven months after tarping, during the fall/winter growing season, there was no significant effect on red sesbania seedling abundance, stump resprout abundance, or height. Germination in the laboratory was significantly reduced by extended exposure to temperatures of 60 C, although lower temperatures did not reduce germination. Red sesbania appears to be resilient to tarping as a control method, at least in the settings studied.
We present simulation results from a version of the Regional Ocean Modeling System modified for ice shelf/ocean interaction, including the parameterisation of basal melting by molecular diffusion alone. Simulations investigate the differences in melting for an idealised ice shelf experiencing a range of cold to hot ocean cavity conditions. Both the pattern of melt and the location of maximum melt shift due to changes in the buoyancy-driven circulation, in a different way to previous studies. Tidal forcing increases both the circulation strength and melting, with the strongest impact on the cold cavity case. Our results highlight the importance of including a complete melt parameterisation and tidal forcing. In response to the 2.4°C ocean warming initially applied to a cold cavity ice shelf, we find that melting will increase by about an order of magnitude (24 × with tides and 41 × without tides).
Excavations to the east of the Roman fort of Inveresk in 2010 partly uncovered remains of a Mithraeum — the first from Scotland and the earliest securely dated example from Britain. A large rectangular sunken feature with lateral benches contained two altars buried face down at its north-western end. One was dedicated to Mithras, with iconography of both Mithras and Apollo as well as libation vessels. The other was dedicated to Sol, with a frieze above showing the Four Seasons. The Sol altar had a recess in the rear for a light which would have shone through his pierced rays, eyes, mouth and nose. Remains of an iron rod behind the nose hint at a more complex arrangement to create special visual or acoustic effects. Paint and plaster traces were recorded on both altars. The dedicator, G(aius) Cas(sius) Fla(…), a centurion, may have been in command of the garrison or of a legionary detachment. Stylistic links, especially in letter form, connect the work to sculptors of Legio XX. The stones and pigments are most likely from local sources. Little of the setting could be explored but there were traces of a precinct. A pit beside the Mithraeum included a large part of a well-used fineware beaker, which represented a deliberate offering. The Supplementary Material available online (http://journals.cambridge.org/bri) contains detailed descriptions of the altars, observations on the stone-working technology, lithology and pigment analysis, with extensive illustrations.
The development of petroleum resources in the UK is not a new phenomenon. Off shore exploration began in the mid-1960s, but the exploitation of conventional hydrocarbons onshore dates back to the end of the First World War, and oil shales were exploited in Scotland for over a century from the middle of the 19th century. Current daily production stands at around 20,000–25,000 barrels of oil equivalent (boe). Despite the popular perception that the development of shale gas will involve the deployment of technologies new to the UK, industry and regulators have already had experience of HF (hydraulic facturing) and directional drilling (DD) in the extraction of conventional petroleum activities. Of the more than 2,000 wells drilled onshore, approximately 200 of those have undergone HF. Indeed, the combination of HF and DD enabled the development in 1979 of the Wytch Farm Field in Dorset, Europe's largest onshore producing field. However, exploration for gas from shale reservoirs (shale gas) has been minimal to date, in part due to public concerns about the technologies involved and the adequacy of the current regulatory framework to prevent environmental harm, including groundwater contamination.
Shale gas, and its associated activity of HF was first brought to the attention of the UK public in the spring of 2011, when Cuadrilla resources undertook HF of an exploration well at Preese Hall, near Blackpool. This HF triggered two mild seismic events in April and May, and resulted in the UK Government imposing a temporary moratorium on shale gas activities while a review of the risks related to HF was undertaken. The Preese Hall incident and its link to HF triggered what has now become a tsunami of community concern and activism, thrusting the activity of HF and the development of shale gas into the spotlight.
In response to the Preese Hall incident a study was undertaken by the Royal Society and the Royal Academy of Engineering (RS & RAE), focusing on the major risks associated with HF as a method of extracting shale gas in the UK. The outcomes of the study were made available in the publication Shale Gas Extraction in the UK: A Review of Hydraulic Fracturing (the RS & RAE Review).

The United Kingdom is poised tentatively on the edge of shale gas development. The first steps in this direction at Preese Hall near Blackpool in the spring of 2011 resulted in two minor seismic events that not only prompted government and academic inquiries, but also heralded in an era of public objection to shale gas development in the UK in general, and to the technique of hydraulic fracturing (HF), or ‘fracking’, in particular. Despite suggestions that the tremors induced were minor, the UK government clearly felt compelled to respond to public concerns.
The legal framework regulating the exploration for and production of shale gas was immediately subjected to close scrutiny. A temporary moratorium was imposed while the Preese Hall incident was investigated under the auspices of the Royal Society and the Royal Academy of Engineering (RS & RAE), the outcome of which was published as Shale Gas Extraction in the UK: A Review of Hydraulic Fracturing (the review). In addition, Cuadrilla, the operator of the shale gas exploration well at Preese Hall, commissioned a series of studies to examine to possible relationship between hydraulic fracturing and seismic activity. The Department of Energy and Climate Change (DECC) requested a review of these reports by three experienced academics and practitioners: Professor Peter Styles of Keele University, Dr Brian Baptie of the British Geological Survey, and Dr Christopher Green of G Frac Technologies (the expert team). The resultant report, Preese Hall Shale Gas Fracturing: Review and Recommendations for Induced Seismic Mitigation, addressed the question of whether HF as a practice in shale gas development is safe. It focused on aquifer contamination, well integrity and seismicity.
Following this comprehensive review of shale gas activites in the UK, some regulatory reform occurred and the moratorium was lift ed. However, the review, and subsequent legislative reform has so far failed to quell the public concerns regarding shale gas exploration. Such concern was displayed in the summer of 2013 at Balcombe, England in relation to the granting of permission to Cuadrilla to drill a shale gas exploration well within Petroleum and Development Licence (PEDL) 244 at a vertical depth of approximately 3,000 feet with a horizontal leg. Whilst the test well was commenced in August 2013, it was later scaled back due to the prolonged public protest.
The purpose of this study was to test the usefulness of the attribution model (Corrigan, Markowitz, Watson, Rowan & Kubiak, 2003; Weiner, 1995) in a Chinese cultural context to explain Chinese college students’ perceptions of discrimination toward people with mental illness. A total of 293 college students (male = 142; female = 151; age from 18 to 22) completed an Attribution Questionnaire (AQ) after reading vignettes, consisting of a male who either used illicit drugs or had a traumatic brain injury. Data were analysed using a hierarchical regression to determine the amount of variance accounted for in discriminatory behaviours by the attribution model. The results showed, when controlling for all other factors, that controllability and the three emotions (pity, anger, and fear) were found to be significant predictors of discrimination. The relationship between controllability, responsibility, and discrimination was not consistent with the attribution model since responsibility did not mediate the controllability of cause. These results provide support for the idea that disability attributions are culturally influenced.
New radiocarbon dates for the Neolithic settlement at Pool on Sanday, Orkney, are interpreted in a formal chronological framework. Phases 2.2 and 2.3, during which flat-based Grooved Ware pottery with incised decoration developed, have been modelled as probably dating to between the 31st and 28th centuries cal bc. There followed a hiatus of a century or so, before the resumption of occupation in Phase 3, which has a different Grooved Ware style featuring the use of applied decoration. This has been modelled as probably dating from the 26th to the 24th centuries cal bc. The implications of these results are discussed for the emergence and development of Grooved Ware, and for the trajectory of settlement and monumentality on Sanday.
