Enhancing Indigenous content in arts curricula through service learning with Indigenous communities

Executive summary At the heart of this project has been the desire to enhance the way in which Aboriginal and Torres Strait Islander cultural content is embedded in higher education arts curricula. It comes at a time when higher education institutions are facing growing pressure to make curriculum content more representative of and responsive to Aboriginal and Torres Strait Islander culture. In response, many Australian universities have established formal initiatives to embed Aboriginal and Torres Strait Islander culture and intercultural competency across the curriculum. This has taken the form of policies and reconciliation action plans, community engagement initiatives, networks and councils of Elders. Despite the proliferation of such initiatives, the incorporation of Aboriginal and Torres Strait Islander perspectives into higher education curricula and cultures remains a challenging political, social and practical task. This project has sought to address this challenging task by positioning arts based service learning (ABSL) as a strategy through which Australian higher education institutions can promote Aboriginal and Torres Strait Islander cultural content for students in ways that also directly support Aboriginal and Torres Strait Islander communities

The workload implications of haptic displays in multi-display environments such as the cockpit: Dual-task interference of within-sense haptic inputs (tactile/proprioceptive) and between-sense inputs (tactile/proprioceptive/auditory/visual)

Visual workload demand within the cockpit is reaching saturation, whereas the haptic sense (proprioceptive and tactile sensation) is relatively untapped, despite studies suggesting the benefits of haptic displays. MRT suggests that inputs from haptic displays will not interfere with inputs from visual or auditory displays. MRT is based on the premise that multisensory integration occurs only after unisensory processing. However, recent neuroscientific findings suggest that the distinction between unisensory versus multisensory processing is much more blurred than previously thought. This programme of work had the following two research objectives: 1. To examine whether multiple haptic inputs can be processed at the same time without performance decrement - Study One 2. To examine whether haptic inputs can be processed at the same time as visual or auditory inputs without performance decrement - Study Two In Study One participants performed dual-tasks, consisting of same-sense tasks (tactile or proprioceptive) or different-sense tasks (tactile and proprioceptive). These tasks also varied in terms of processing code, in line with MRT. The results found significantly more performance decrement for the same-sense dual-tasks than for the different-sense dual-tasks, in accordance with MRT, suggesting that performance will suffer if two haptic displays of the same type are used concurrently. An adjustment to the MRT model is suggested to incorporate these results. In Study Two, participants performed different-sense dual-tasks, consisting of auditory or visual tasks with tactile or proprioceptive tasks. The tasks also varied in terms of processing code. Contrary to MRT, the results found that when processing code was different, there was significant performance decrement for all of the dual-tasks, but not when processing code was the same. These results reveal an exception to two key MRT rules, the sensory resource rule and the processing code rule. It is suggested that MRT may be oversimplistic and other factors highlighted by recent neuroscientific research should be taken into account in theories of dual-task performance

Programming Languages and Systems

This open access book constitutes the proceedings of the 29th European Symposium on Programming, ESOP 2020, which was planned to take place in Dublin, Ireland, in April 2020, as Part of the European Joint Conferences on Theory and Practice of Software, ETAPS 2020. The actual ETAPS 2020 meeting was postponed due to the Corona pandemic. The papers deal with fundamental issues in the specification, design, analysis, and implementation of programming languages and systems

Facilitation of healthy self-management of female educators' experience of their aggression within a secondary school context

D.Ed. (Psychology of Education)Daily media reports alert nations worldwide of the ever escalating aggressive acts of behaviour over many decades and has subsequently aroused deep concern as progressive growth In population becomes increasingly evident. Our future lies in the hands of our youth who are exposed to a wide range of educational, family, employment, political and health challenges that depart in major ways from those of young people one or two generations ago. The educational challenge is not limited to academia solely but more Importantly focuses on the upholding and envisioning of a values-based education that stirs the conscience of a nation encouraging moral, responsible law abiding citizens. This responsibility lies squarely on the shoulders of our female educators amongst others in a democratic educational system. Female educators outweigh males significantly in number in our educational system yet research reveals that some female educators are not given sufficient support, acknowledgement and recognition for their committed roles In education. Faced with overwhelming demands female educators are expected to fulfil multiple roles and yet maintain a healthy balance between work commitments and family responsibilities. Some cultures have the added expectation that women bear the prime responsibility for childcare and domestic work. As a result, notable gender differences in aggression arise primarily from contrasting gender roles which augments into the workplace. The overall purpose of the study is to develop and describe a psycho-educational programme to be used as a framework of reference to facilitate the healthy self-management of secondary school female educators' experience of their aggression. The implementation and evaluation of the programme will serve as a facilitative process through the promotion of personal growth and the mobilisation of female educators to constructively self-manage their experience of aggression. Attempts to meet this broad objective were accomplished by employing an explorative, descriptive and contextual research design. In this research study field notes were used in conjunction with eight in-depth phenomenological Interviews conducted with female educators. The findings of their experiences of aggression at their secondary school evolved around their associated emotions; the resultant measures of support and the coping strategies the female educators sought as a current means of addressing their mental health status as educators and community stakeholders. The data analysis of the findings revealed that female educators do have the potential to facilitate and mobilise the available resources in order to promote their own mental health and grow towards wholeness. The future scenarios that schools are likely to face are both challenging and daunting: can schools actively shape the future by listening to the heartbeat of its female educators or merely respond to its exigencies. The liberal awakenings and gradual movement from oppression to equality for the female In South Africa as well as Issues of aggression, political violence, single parenting and abuse on women further extrapolate the need to listen to the voices of women. An awareness of their plight as evidenced In this study will hopefully draw attention to their needs and bring offers of subsequent support to the mothers of our nation which will inadvertently Impact on our youth ... our future as a nation. A shared vision building process will thus only become a living force when each Individual truly believes s/he can shape her/his future. The ability of our educational system to compete in an Increasingly global economy depends on our ability to prepare both learners and educators for new or changing landscapes

Prefigurative Politics: Perils and Promise

Many recent social movements have been characterised by their commitment to direct democratic decision-making procedures and leaderless, non-hierarchic organizational structures. This political tendency also implies the search for autonomy from existing political institutions and practises. Movements seek instead to embody in the political action itself the social relations, ways of collective decision-making and values that are ultimately desired for the whole society. This prefigurative approach to social change is often criticized for being naiive or marginal. This thesis argues first that this is not the case, but that prefigurative politics is misunderstood due to its differing view on questions of strategy, organisation and ultimately the possibility of fundamental societal change. The dissertation first outlines the often implicit strategy or vision of change underpinning prefigurative politics. It then identifies as the key challenge for prefigurative movements their ability to avoid reproducing oppressive forms of power, ‘power-over.’ This understudied aspect is investigated through extensive ethnographic field research with the unemployed workers movement, MTD Lanús in Buenos Aires, and the Zapatista movement in Mexico. The thesis concludes that it seems impossible to completely avoid reproducing old forms of power. Often key individuals in the movements end up in a paradoxical position whereby, in an effort to ensure the group’s prefigurative nature, these individuals enjoy non-prefigurative influence. The findings imply that the state and corresponding political forms and practise are not the only source of hierarchic pressures. As such, it would be more useful to view prefigurative political action as desirable, yet impossible

Space transfer vehicle concepts and requirements, volume 2, book 1

The objective of the systems engineering task was to develop and implement an approach that would generate the required study products as defined by program directives. This product list included a set of system and subsystem requirements, a complete set of optimized trade studies and analyses resulting in a recommended system configuration, and the definition of an integrated system/technology and advanced development growth path. A primary ingredient in the approach was the TQM philosophy stressing job quality from the inception. Included throughout the Systems Engineering, Programmatics, Concepts, Flight Design, and Technology sections are data supporting the original objectives as well as supplemental information resulting from program activities. The primary result of the analyses and studies was the recommendation of a single propulsion stage Lunar Transportation System (LTS) configuration that supports several different operations scenarios with minor element changes. This concept has the potential to support two additional scenarios with complex element changes. The space based LTS concept consists of three primary configurations--Piloted, Reusable Cargo, and Expendable Cargo
