Near-real-time service provision during effusive crises at Etna and Stromboli: basis and implementation of satellite-based IR operations

Using the NEODAAS-Dundee AVHRR receiving station (Scotland), NEODAAS-Plymouth can provide calibrated brightness temperature data to end users or interim users in near-real time. Between 2000 and 2009 these data were used to undertake volcano hot spot detection, reporting and time-average discharge rate dissemination during effusive crises at Mount Etna and Stromboli (Italy). Data were passed via FTP, within an hour of image generation, to the hot spot detection system maintained at Hawaii Institute of Geophysics and Planetology (HIGP, University of Hawaii at Manoa, Honolulu, USA). Final product generation and quality control were completed manually at HIGP once a day, so as to provide information to onsite monitoring agencies for their incorporation into daily reporting duties to Italian Civil Protection. We here describe the processing and dissemination chain, which was designed so as to provide timely, useable, quality-controlled and relevant information for ‘one voice’ reporting by the responsible monitoring agencies.

Radiological protection and the exposure of animals as patients in veterinary medicine

It is apparent that most of the techniques that make use of ionising radiation in human medical practices are now being applied in veterinary medicine. Steps are being taken by the IAEA to provide guidance for humans involved in such practices, but there appears to be no international initiative that considers the protection or welfare of the animal as a patient. There is therefore a risk that the deliberate exposure of an animal, particularly in the therapeutic application of radiation, could do more harm than good. In the light of recent developments in dosimetric modelling and the application of known effects of radiation on different types of animals, for the purposes of the protection of biota in an environmental context, it is argued that it would be sensible now to start a serious consideration of this issue. Some suggestions are made with regard to a number of areas that could be considered further, both specifically and with regard to the field of radiological protection as a whole.

Time series wind power forecasting based on variant Gaussian process and TLBO

Due to the variability and stochastic nature of wind power system, accurate wind power forecasting has an important role in developing reliable and economic power system operation and control strategies. As wind variability is stochastic, Gaussian Process regression has recently been introduced to capture the randomness of wind energy. However, the disadvantages of Gaussian Process regression include its computation complexity and incapability to adapt to time varying time-series systems. A variant Gaussian Process for time series forecasting is introduced in this study to address these issues. This new method is shown to be capable of reducing computational complexity and increasing prediction accuracy. It is further proved that the forecasting result converges as the number of available data approaches innite. Further, a teaching learning based optimization (TLBO) method is used to train the model and to accelerate
the learning rate. The proposed modelling and optimization method is applied to forecast both the wind power generation of Ireland and that from a single wind farm to show the eectiveness of the proposed method.

Exploring the joint compositional variability of major components and trace elements in the Tellus soil geochemistry survey (Northern Ireland)

The complexity of modern geochemical data sets is increasing in several aspects (number of available samples, number of elements measured, number of matrices analysed, geological-environmental variability covered, etc), hence it is becoming increasingly necessary to apply statistical methods to elucidate their structure. This paper presents an exploratory analysis of one such complex data set, the Tellus geochemical soil survey of Northern Ireland (NI). This exploratory analysis is based on one of the most fundamental exploratory tools, principal component analysis (PCA) and its graphical representation as a biplot, albeit in several variations: the set of elements included (only major oxides vs. all observed elements), the prior transformation applied to the data (none, a standardization or a logratio transformation) and the way the covariance matrix between components is estimated (classical estimation vs. robust estimation). Results show that a log-ratio PCA (robust or classical) of all available elements is the most powerful exploratory setting, providing the following insights: the first two processes controlling the whole geochemical variation in NI soils are peat coverage and a contrast between “mafic” and “felsic” background lithologies; peat covered areas are detected as outliers by a robust analysis, and can be then filtered out if required for further modelling; and peat coverage intensity can be quantified with the %Br in the subcomposition (Br, Rb, Ni).

Climate change and the long-term viability of the World’s busiest heavy haul ice road

Climate models project that the northern high latitudes will warm at a rate in excess of the global mean. This will pose severe problems for Arctic and sub-Arctic infrastructure dependent on maintaining low temperatures for structural integrity. This is the case for the economically important Tibbitt to Contwoyto Winter Road (TCWR)—the world’s busiest heavy haul ice road, spanning 400 km across mostly frozen lakes within the Northwest Territories of Canada. In this study, future climate scenarios are developed for the region using statistical downscaling methods. In addition, changes in lake ice thickness are projected based on historical relationships between measured ice thickness and air temperatures. These projections are used to infer the theoretical operational dates of the TCWR based on weight limits for trucks on the ice. Results across three climate models driven by four RCPs reveal a considerable warming trend over the coming decades. Projected changes in ice thickness reveal a trend towards thinner lake ice and a reduced time window when lake ice is at sufficient thickness to support trucks on the ice road, driven by increasing future temperatures. Given the uncertainties inherent in climate modelling and the resultant projections, caution should be exercised in interpreting the magnitude of these scenarios. More certain is the direction of change, with a clear trend towards winter warming that will reduce the operation time window of the TCWR. This illustrates the need for planners and policymakers to consider future changes in climate when planning annual haulage along the TCWR.

MODERN SPORT COACHING AND THE LAW: IMPLICATIONS FOR COACH EDUCATION

Introduction
The intersection between the law of negligence and sport coaching in the UK is a developing area (Partington, 2014; Kevan, 2005). Crucially, since the law of negligence may be regarded as generally similar everywhere (Magnus, 2006), with the predominance of volunteer coaches in the UK reflective of the majority of countries in the world (Duffy et al., 2011), a detailed scrutiny of this relationship from the perspective of the coach uncovers important implications for coach education beyond this jurisdiction.  
Argumentation
Fulfilment of the legal duty of discharging reasonable care may be regarded as consistent with the ethical obligation not to expose athletes to unreasonable risks of injury (Mitten, 2013). More specifically, any ‘profession’ requiring ‘special skill or competence’ (Bolam v Friern Hospital Management Committee [1957] 1 WLR 582), including the coaching of sport (e.g., Davenport v Farrow [2010] EWHC 550), requires a higher standard of care to be displayed than would be expected of the ordinary reasonable person (Lunney & Oliphant, 2013; Jones & Dugdale, 2010). For instance, volunteer coaches with no formal qualifications (e.g., Fowles v Bedfordshire County Council [1996] ELR 51) would be judged by this benchmark of professional liability (Powell & Stewart, 2012). Further, as the principles of coaching are constantly assessed and revised (Cassidy et al., 2009; Taylor & Garratt, 2010), so too is the legal standard of care required of coaches (Powell & Stewart, 2012). Problematically, ethical concerns may include coaches being unwilling to increase knowledge, abusive treatment of players and incompetence/inexperience (Haney et al., 1998). These factors accentuate coaches’ exposure to civil liability.
Implications
It is imperative that coaches have an awareness of this emerging intersection and develop a ‘proactive risk assessment lens’ (Hartley, 2010). In addition to supporting the professionalisation of sport coaching, coach education/CPD focused on the legal and ethical aspects of coaching (Duffy et al., 2011; Telfer, 2010; Haney et al., 1998) would enhance the safety and welfare of performers, safeguard coaches from litigation risk, and potentially improve all levels of coaching (Partington, 2014). Interestingly, there is evidence to suggest a demand from coaches for more training on health and safety issues, including risk management and (ir)responsible coaching (Stirling et al., 2012). Accordingly, critical examination of the issue of negligent coaching would inform coach education by: enabling the modelling and sharing of best practice; unpacking important ethical concerns; and, further informing the classification of coaching as a ‘profession’.
