Poverty, Prosperity and the Challenges of the Good Company

The articles in this volume originate from papers delivered at the 9th International Conference on Catholic Social Thought and Management Education at De La Salle and Ateneo Universities in Manila, Philippines (February 26–28, 2015). The theme of the conference was “Poverty, Prosperity and the Purpose of Business” within the Catholic social tradition. In attendance were approximately 300 participants representing 22 countries from 80 Catholic colleges and universities. They came from disciplines in management, philosophy, finance, accounting, theology, marketing, economics, and others. There were also leaders from business, many of whom were from the Philippines, who brought their experiences to bear on the conversations. Along with this diversity of education and experience were people of different faith traditions whose moral and spiritual commitments run deep on the importance of mission and identity of Catholic universitie

Art, Artists and Pedagogy

This volume has been brought together to generate new ideas and provoke discussion about what constitutes arts education in the twenty-first century, both within the institution and beyond. Art, Artists and Pedagogy is intended for educators who teach the arts from early childhood to tertiary level, artists working in the community, or those studying arts in education from undergraduate to Masters or PhD level

Architects of time: Labouring on digital futures

Drawing on critical analyses of the internet inspired by Gilles Deleuze and the Marxist autonomia movement, this paper suggests a way of understanding the impact of the internet and digital culture on identity and social forms through a consideration of the relationship between controls exercised through the internet, new subjectivities constituted through its use and new labour practices enabled by it. Following Castells, we can see that the distinction between user, consumer and producer is becoming blurred and free labour is being provided by users to corporations. The relationship between digital technologies and sense of community, through their relationship to the future, is considered for its dangers and potentials. It is proposed that the internet may be a useful tool for highlighting and enabling social connections if certain dangers can be traversed. Notably, current remedies for the lack of trust on the internet are questioned with an alternative, drawing on Zygmunt Bauman and Georg Simmel, proposed which is built on community through a vision of a ‘shared network’

A modelling framework for virtual power plants under uncertainty

The increased integration of renewable energy sources (RES) and distributed energy resources (DER) into electrical networks is causing operational challenges. The reduction in conventional generators, which would traditional provide the reliability and security services for electrical networks, means that these services must now be supplied by other resources. Simultaneously, the intermittency of RES and the lack of visibility of DER means that in some cases these services are required more frequently to maintain a reliable electrical grid. If RES and DER are aggregated and properly controlled in a virtual power plant (VPP) they have the potential to provide network services as well as increase their profitability. The operation of a VPP is a complex problem. While this problem has been examined by numerous authors, no operating framework has been previously proposed that includes consideration of: participation in multiple markets; provision of network and contractual services; modelling of network power flows and voltages; interactions between multiple energy vectors; uncertainty in operational forecasts and; tractability for short dispatch periods. These are key properties for a comprehensive framework that fully captures and unlocks the potential of a VPP. This thesis presents the design and application of a VPP operational framework that incorporates these six key properties. This optimisation-based framework is decomposed into three optimisations to integrate these properties in a tractable manner. This framework is applied to various realistic case studies to prove the efficacy of the proposed approach. The application of this framework demonstrates that the combination of scenario-based optimisation and receding horizon control used is effective at mitigating the effects of uncertainty. The inclusion of short dispatch periods is shown to be key for revenue generation in markets with short dispatch windows. In addition, the application of this framework demonstrates the ability of a VPP to participate in multiple markets and services, and that doing so is essential for maximising VPP revenue. Moreover, the integration of hydrogen resources into the electrical grid provides flexibility that can be assigned to various markets and services. Furthermore, operating in multiple markets fundamentally changes the operational strategy of hydrogen resources, and can increase the amount of hydrogen that can be profitably generated. Additionally, the convex relaxation used for the dispatch of resources is sufficiently accurate to allow a VPP to maintain a network within allowable limits whilst maintaining problem tractability. Lastly, the framework is versatile enough to be utilised by other entities (such as a distribution system operator), or for different purposed (such as techno-economic analysis for business case assessments)

TRANSMISSION OF VIBRATION ABOUT THE KNEE

The purpose of this study was to examine and describe effects of knee flexion angle, stance width and vibration platform frequency on the transmission of vertical acceleration about the knee. Fifteen adults were exposed to various vibration conditions while standing on a side-to-side vibration platform. Vertical acceleration data, expressed as transmission, were shown to be attenuated for all vibration conditions. A larger degree of knee flexion however, was conducive to greater attenuation about the knee. Such information may be used to develop vibration training programs with a more thorough understanding of effects of vibration

Defining and quantifying fatigue in the rugby codes

The rugby codes (i.e., rugby union, rugby league, rugby sevens [termed 'rugby']) are teamsports that impose multiple complex physical, perceptual, and technical demands on players which leads to substantial player fatigue post-match. In the post-match period, fatigue manifests through multiple domains and negatively influences recovery. There is, however, currently no definition of fatigue contextualised to the unique characteristics of rugby (e.g., locomotor and collision loads). Similarly, the methods and metrics which practitioners consider when quantifying the components of post-match fatigue and subsequent recovery are not known. The aims of this study were to develop a definition of fatigue in rugby, to determine agreement with this common definition of fatigue, and to outline which methods and metrics are considered important and feasible to implement to quantify post-match fatigue. Subject matter experts (SME) undertook a two-round online Delphi questionnaire (round one; n = 42, round two; n = 23). SME responses in round one were analysed to derive a definition of fatigue, which after discussion and agreement by the investigators, obtained 96% agreement in round two. The SME agreed that fatigue in rugby refers to a reduction in performance- related task ability which is underpinned by time-dependent negative changes within and between cognitive, neuromuscular, perceptual, physiological, emotional, and technical/tactical domains. Further, there were 33 items in the neuromuscular performance, cardio-autonomic, or self-report domains achieved consensus for importance and/or feasibility to implement. Highly rated methods and metrics included countermovement jump force/power (neuromuscular performance), heart rate variability (cardio-autonomic measures), and soreness, mood, stress, and sleep quality (self-reported assessments). A monitoring system including highly-rated fatigue monitoring objective and subjective methods and metrics in rugby is presented. Practical recommendations of objective and subjective measures, and broader considerations for testing and analysing the resulting data in relation to monitoring fatigue are provided.</p

Low Levels of after School-Hours Social Interaction and Physical Activity of 5-7 Year Olds

As part of a cluster randomized controlled trial (Bundy et al., 2017), the after school-hours activities of 5-7 year old children were recorded by parents and other adult carers on four consecutive weekdays between 3:30pm-7:00pm. Records of time use showed most time was spent indoors in activities involving low levels of physical activity. The most-frequently-recorded activity was screen time, accounting for approximately one quarter of all activities. Higher levels of physical activity were reported when children were outdoors (19.5% of time) and/or with peers (9.58%). If an adult was present, highest activity levels of children occurred when the child was with a teacher/carer (6.07%). Although concern is frequently raised about children spending too much time in organized activities, these structured forms of out-of-school choices accounted for only 8.09% of recordings. The results of the current study strengthen the evidence base, supporting the need to optimise out-ofschool times with more developmentally important social and physical contexts. We discuss ways in which context may support or inhibit opportunities physical activity in after school-hours activities
