eCommerce, Brexit, new safety and security concerns are only a few examples of the challenges that government organisations, in particular customs administrations, face today when controlling goods crossing borders. To deal with the enormous volumes of trade customs administrations rely more and more on information technology (IT) and risk assessment, and are starting to explore the possibilities that data analytics (DA) can offer to support their supervision tasks. Driven by customs as our empirical domain, we explore the use of DA to support the supervision role of government. Although data analytics is considered to be a technological breakthrough, there is so far only a limited understanding of how governments can translate this potential into actual value and what are barriers and trade-offs that need to be overcome to lead to value realisation. The main question that we explore in this paper is: How to identify the value of DA in a government supervision context, and what are barriers and trade-offs to be considered and overcome in order to realise this value? Building on leading models from the information system (IS) literature, and by using case studies from the customs domain, we developed the Value of Data Analytics in Government Supervision (VDAGS) framework. The framework can help managers and policy-makers to gain a better understanding of the benefits and trade-offs of using DA when developing DA strategies or when embarking on new DA projects. Future research can examine the applicability of the VDAGS framework in other domains of government supervision. 相似文献

Post-apartheid South Africa manifests poor social indicators with over half the population living below the poverty line and the worst levels of inequality in the world, with much work needed to overcome the skewed legacy of apartheid. Sport suffered in this system resulting in unequal access to sporting facilities and opportunities, meaning many South Africans cannot exercise their right to play. Despite this legacy, sport can fulfil a vital developmental role in alleviating some of these issues. The state has a major role to play but it must be supported by civil society and non-governmental organisations (NGOs) who have the ability to deliver in situations where government has struggled. This article researches the opportunities and challenges NGOs encounter when using sport for development within the education system, in post-apartheid South Africa. This study used a qualitative approach to collect data on the opportunities and challenges encountered by two NGOs based in Cape Town that use sport as a means of development, but in markedly different ways. The study suggests that NGOs face a variety of conceptual, technical, logistical and organisational challenges using sport in schools and should enact certain measures to reduce resistance from educators and ensure successful programmes. The interaction between NGOs, schools and the state Department of Education is a complicated process that presents obstacles and opportunities. Nevertheless, despite these challenges it is clear NGOs can support schools in South Africa to optimise their physical activity programmes in the backdrop of a stagnating education system and a lack of sporting support from the government. NGOs in an educational setting such as schools operate in what Houlihan has identified as a crowded policy space. Yet, the observations in this study suggest that, particularly in the context of education, a partnership policy model of NGO work is preferred. 相似文献

Sports performance testing is one of the most common and important measures used in sport science. Performance testing protocols must have high reliability to ensure any changes are not due to measurement error or inter-individual differences. High validity is also important to ensure test performance reflects true performance. Time-trial protocols commonly have a coefficient of variation (CV) of <5%, however, familiarization, well-trained subjects and/or conducting the trial outdoors in the athlete’s most familiar environment can lead to CVs of < 1%. Long duration time-trials or the inclusion of sprints within a time-trial appears to not negatively influence reliability. Few studies have assessed the validity of endurance performance tests, and as such more research should evaluate different ways of simulating outdoor performances in the laboratory. The use of warm-up, simulation of convection load, and implementation of race specific hydration practices are important considerations for researchers regarding test validity. 相似文献

Abstract The aim of this study was to determine whether endurance training in athletes induces airway inflammation and pulmonary function disorders. Respiratory pattern and function were analysed in ten healthy endurance runners at rest, during sub-maximal exercise, and during the recovery. Inflammatory cells and metabolites (histamine, interleukin-8, and leukotriene E4) were measured in sputum at rest and after exercise. The experiments were conducted on three different occasions (basic endurance training, pre-competitive and competitive periods). In spite of the absence of post-exercise spirometric changes and respiratory symptoms, airway cells counts and inflammatory markers changed significantly. At the beginning of the experiment, athletes' induced sputum showed an abundance of macrophages compared with neutrophils. We found a high percentage of neutrophils during the pre-competitive and competitive periods of the sport season (41% and 37%), a significant increase in macrophage counts during the pre-competitive period (51%), and a significant rise in total cells, interleukin-8, leukotriene E4, and histamine during the competitive period. In conclusion, one year's training increased markers of inflammation in the airways of endurance runners without symptoms or changes in pulmonary function, suggesting that airway inflammation is of insufficient magnitude to markedly impact lung function in healthy athletes. 相似文献

Abstract Before completing a team-based dart-throwing activity, 80 undergraduates were randomly assigned to one of three pre-performance self-talk conditions: (a) self-talk statements that focused upon one's personal capabilities, (b) self-talk statements emphasizing the group's capabilities, or (c) a control condition where neutral statements were implemented. Participants in all conditions subsequently rated their confidence in their own (i.e. self-efficacy) as well as their team's (i.e. collective efficacy) capabilities, before carrying out the task. Overall, self-efficacy, collective efficacy, and performance indicators were all greatest for individuals who practised self-talk focusing on the group's capabilities, as opposed to individual-focused and neutral conditions. Findings are considered with respect to their novel theoretical contribution to the social cognition literature and their implications for fostering efficacy perceptions and team performance. 相似文献

AbstractThe International Physical Activity Questionnaire (IPAQ) has been widely used to assess physical activity in healthy populations. The present study compared physical activity assessed by the long, self-administrated version of the International Physical Activity Questionnaire with physical activity assessed by accelerometry in patients with fibromyalgia. A total of 99 (five men) participants with fibromyalgia completed the International Physical Activity Questionnaire and wore an accelerometer for nine consecutive days. We analysed the correlations of physical activity expressed as min · day?1 of light, moderate, vigorous, and moderate to vigorous (MVPA) intensity, as well as time spent sitting, by the International Physical Activity Questionnaire and accelerometry by Spearman correlations. Bland and Altman plots were performed to verify the agreements between both instruments. The results showed weak yet significant correlations (Rs = 0.15–0.39, all P < 0.05) in all physical activity intensities between the two instruments, except for sedentary time. The highest correlations were observed for physical activity at home or in garden (Rs = 0.297, P < 0.01). The results suggest that the long self-administrated International Physical Activity Questionnaire is a questionable instrument to assess physical activity in patients with fibromyalgia. Therefore, physical activity measurement in fibromyalgia patients should not be limited solely to self-reported measures. 相似文献

ABSTRACTThis article outlines some of the opportunities and challenges of changing what the library “brand” means to academic and professional services staff in the rapidly changing environment of UK higher education, taking the University of Leicester as a case study. It makes a practitioner contribution to the growing body of evidence of how libraries are extending their role and how their customers are responding. It begins by considering the drivers for change in the higher education and scholarly information environments and how these are influencing the development of library services at the University of Leicester. The topics considered include researcher development, Digital Humanities, Open Access, independent learning, and curating the university's own information assets. The impact of these developments is outlined and how an evolving approach to strategic marketing is beginning to change perceptions as the boundaries of the library's role extend. 相似文献
