Description: Risk management strategies have been used in a wide range of sports. Many issues involved in the implementation of risk management models in sport have not been investigated especially the sport specific and location specific nature of such models. The aim of th1s study was to ascertain the usefulness of Occupational Health & Safety risk management (RM) models in a mainly voluntary sporting organisation and to investigate the requirements of a netball population in developing "user friendly" risk management plans. The industry RM plans were trialled in a rural setting at various netball associations over a six week period. After these trials focus groups and interviews were conducted and the trials evaluated. The requirements of the netball population for a RM plan were investigated using focus groups from regional and rural areas. The industry RM models presented were not generally accepted by the trial participants. They found that the level of expertise required did not exist in netball at the club/team level. The focus groups on the needs of netball for a user friendly model brought out a number of issues including the specifjc needs of rural football/netball leagues. the need to develop strategies for all levels of netball (coach. player. umpire. administrator). Barriers to the uptake of risk 'management models were discussed. An effective RM plan can b~ .developed for voluntary sports associations but they must be specific to the sport and flexible. The RM plan must also take into accoWlt the barriers to implementation fof each sporting culture.

Description: Risk matrices are used during hazard identification and risk assessment processes and provide a construct for people needing to display the two variable relationship between likelihood and consequence that are considered to be the elements of risk. The purpose of a matrix is to reduce the continuum of risk into ranges or bands such as high, medium or low. These bands are often allocated colours such as red for the highest risks to green for the lowest. Sometimes each band in a matrix is allocated a numerical value or range. The multiplication of likelihood and consequence implies a quantitative basis although it may not be widely understood. The multiplication operator produces lines of equal risk that a matrix cannot model accurately and thereby introduces risk reversal errors. Weaknesses in matrices are further compounded by subjectivity and bias introduced by users and the value of such tools is brought into doubt. A shift of emphasis from the risk assessment stage to the risk control stage of a hazard management process may lead to better and more timely decision making and better use of resources.

Description: One of the significant economic benefits to communities around the world of having pristine forest catchments is the supply of substantial quantities of high quality potable water. This supports a saving of around US$ 4.1 trillion per year globally by limiting the cost of expensive drinking water treatments and provision of unnecessary infrastructure. Even low levels of contaminants specifically organics and metals in catchments when in a mobile state can reduce these economic benefits by seriously affecting the water quality. Contamination and contaminant mobility can occur through natural and anthropogenic activities including forest fires. Moderate to high intensity forest fires are able to alter soil properties and release sequestered metals from sediments, soil organic matter and fragments of vegetation. In addition, the increase in post-fire erosion rate by rainfall runoff and strong winds facilitates the rapid transport of these metals downslope and downstream. The subsequent metal deposition in distal soil and water bodies can influence surface water quality with potential impacts to the larger ecosystems inclusive of negative effects on humans. This is of substantial concern as 4 billion hectares of forest catchments provide high quality water to global communities. Redressing this problem requires quantification of the potential effects on water resources and instituting rigorous fire and environmental management plans to mitigate deleterious effects on catchment areas. This paper is a review of the current state of the art literature dealing with the risk of post-fire mobilization of the metals into surface water resources. It is intended to inform discussion on the preparation of suitable management plans and policies during and after fire events in order to maintain potable water quality in a cost-effective manner. In these times of climate fluctuation and increased incidence of fires, the need for development of new policies and management frameworks are of heighted significance. © 2017 Elsevier B.V.

Description: Plug in hybrid electric vehicles (PHEVs) can be a strategic source to mitigate risk of supply insecurity in an active distribution network. This study proposes a new methodology to quantify the risk of supply insecurity with weather condition based operation of PHEVs in an active distribution network. The approach divides operating characteristics of PHEVs into charging, discharging and null. Operation of PHEVs with change in weather conditions, intermittent characteristics of distributed generation, sector customer demand characteristics and random outages of components are modelled on Markov-chain Monte Carlo simulation. A set of case studies are performed considering distributed operation of PHEVs as oppose to central operation of conventional units. Results suggest that distributed operation of PHEVs can potentially mitigate risk of supply insecurity of moderately stressed networks. Highly stressed networks, which are operated with PHEVs, need supplementary supports from conventional units to mitigate risk of supply insecurity.

Description: Objectives Exertional heat illnesses (EHI) can occur when sport is played in hot and humid environments, such as those common across Asia. Measures to reduce the risk of EHI are important; however, causal data on EHI occurrence are limited and challenging to capture. To gain an initial understanding of EHI risks, we aimed to assess the risk perceptions of EHI of youth cricketers. Methods A descriptive cross-sectional survey, comprised of 14 questions on EHI risks, was conducted with 365 Sri Lankan junior male cricketers (age=12.9±0.9 years) who typically play in hot and humid conditions. Results For climate related risks, relative humidity was perceived as having a low risk of EHI compared with ambient temperature. The EHI risk associated with wearing protective gear, as commonly used in cricket, was perceived as low. Most junior cricketers perceived a low level of risk associated with recommended preventive measures such as body cooling and heat-acclimatisation. Conclusion This is the first study to explore EHI risk perceptions in any sporting context. Young players may not be mindful of all risks. Therefore, leadership and initiative from competition organisers and parents is required to promote countermeasures.

Risk, education and culture: Interpreting danger as a dynamic, culturally situated process

Description: This introduction presents an overview of the key concepts discussed in the subsequent chapters of this book. The book focuses upon the definition of key terms and the consideration of different cultural risk perspectives. It defines the terms culture, education and risk, and discusses the links between these three concepts. The book considers risk and culture, focusing on four different risk theories, namely the psychometric risk paradigm, the 'risk society' perspective, cultural hermeneutic approaches to risk and risk discourse analysis. The 'risk society' approach attempts to understand hazards that operate at a macro-political level. Drawing upon social anthropology and interpretative sociology, cultural, hermeneutic approaches maintain that risk is always social. Therefore, any understanding of risk needs to be situated within the cultural and political settings that gave rise to it. Educational researchers need to adopt the cultural risk perspective that best suits their research question and theoretical disposition.

Description: One of the social memories of the Great War of 1914-1918 focused on soldiers killed in battle, with military cemeteries forming important sites for remembrance. This paper reports the results of an analysis of the visitor books at Tyne Cot Cemetery in Belgium, that was built by the Commonwealth War Graves Commission to hold almost 12,000 graves, most of which contain unidentified remains. Tourist's comments in the books evidenced a strong linguistic ritual, expressing sadness, gratitude, approval of the site and promises to remember and never forget the dead. Very little critique of war, or overt nationalistic sentiment was indicated. While some national preferences for ritualized phrases were shown, there was also an indication of a globally shared memory. © 2015 Elsevier Ltd.

Description: Rivers make a significant contribution in providing goods and services for human well-being. Today, many rivers and streams have been heavily regulated to ensure adequate provision of water resources for anthropogenic uses. Riverine ecosystems, especially those in arid and semi-arid regions, are experiencing severe stress due to the increasing demands on the ecosystem services they provide, coupled with anthropogenic catchment-scale impacts and factors associated with natural and human-induced climate variability and change. In this paper, the various flow components in regulated riverine ecosystems and the methods to determine environmental flows are reviewed. The review also focuses on the concurrent developments of eco-hydrological models and on the new opportunities for improving environmental flows of rivers by sustainably adjusting consumptive flows to fine-tune environmental flows and maximize the ecological benefit. In fact, the present paper highlights the role of consumptive flows, towards improving environmental flows, which has largely been neglected by river scientists and water managers. Indeed, consumptive flows can provide an opportunity to improve and support environmental flows in regulated riverine ecosystems. Addressing these challenges may aid water management efforts in finding sustainable solutions in riverine ecosystems by balancing environmental/ecological and human water requirements. © 2020 E.

Description: As an important branch of the Internet of Things (IoT), the Internet of Vehicles (IoV) has attracted extensive attention in the research field. To deeply study the IoV and build a vehicle spatiotemporal interaction network, it is necessary to use the trajectory data of private cars. However, due to privacy and security protection policies and other reasons, the data set of private cars cannot be obtained, which hinders the research on the social attributes of vehicles in the IoV. Most of the previous work generated the same type of data, and how to generate private car data sets from various existing data sets is a huge challenge. In this paper, we propose a tri-layer framework to solve this problem. First, we propose a novel region division scheme that considers detailed inter-region relations connected by traffic flux. Second, a new spatial-temporal interaction model is developed to estimate the traffic flow between two regions. Third, we devise an evaluation pipeline to validate generation results from microscopic and macroscopic perspectives. Qualitative and quantitative results demonstrate that the data generated in heavy density scenarios can provide strong data support for downstream IoV and mobility research tasks. © 1967-2012 IEEE.
