Reimagining learning spaces : A research report for the Queensland Council for Social Science Innovation

The purpose of the Reimagining Learning Spaces project was to conduct an empirical study that would result in findings to inform the design and use of physical school facilities and examine the ways in which these constructions influence pedagogy. The study focused on newly-established school libraries in Queensland, many of which had been established with funding from the Federal Government’s Building the Education Revolution economic stimulus program. To explore the field, the study sought multiple perspectives that included those of school students as well as teacher-librarians and other key school staff, addressing the following focus question: - How does the physical environment of school libraries influence pedagogic practices and learning outcomes? Further research questions that guided the inquiry included: - What are the implications for teacher-librarians when transitioning into a new library learning space? - How do members of the school community (principals, teachers, teacher-librarians and students) experience the creation of a new school library learning space? - How do school students imagine the design and use of engaging library learning spaces? An extensive review explored Australian and international literature based on the research questions, focused on the following major areas: • School library renewal: trends in reimagining the place of libraries in virtual and real space • School libraries as learning spaces: the expanded role of school libraries in whole-school pedagogical support. • The role of teacher-librarians in new times • Built environments and the implications for learning • Learners and learning in newly established spaces • Learning space design: perspectives, research and principles • Pedagogical principles and voices of experience • Transitions to newly created learning spaces Approach Using an innovative qualitative research design, Reimagining Learning Spaces investigated learner and teacher perspectives across three intersecting domains exploring: - Imagined spaces: learners’ imaginative concepts of learning within engaging learning environments; - Emerging spaces: experiences of teacher-librarians in the transition into new spaces for learning, and - Established spaces: learners’ and teachers’ perceptions of ways in which the physical environment influences and shapes pedagogy. Seven schools that had recently benefitted from the BER program became the research sites at which data were collected from teacher-librarians, teachers, school leaders and students. With this range of participants, an appropriately diverse set of data collection tools was developed, including video interviews, drawings, and focus groups. Evocative narrative case studies (Simons 2009) were developed from the data, representing the voices of users of learning spaces. Key findings The study’s findings are presented in this report and complemented by an array of visual materials on the project web site http:// The report includes: • a set of seven cases studies that reveal nuanced experiences of designing and creating school libraries, based on the narrative of key stakeholders (teacher-librarians, teachers, students and principals) • thematic discussion of student imaginings of their ideal school library, based on drawings and narrative of students at the seven case study schools • critical analysis of the case study and student imaginings, focusing on implications for (re)designing school learning spaces and pedagogy, and responding to the study’s overarching research question - .17 recommendations to support: designing, transitioning and reimagining pedagogy; leadership; and policy development

Achieving world leadership in sustainable buildings - a Brisbane case study

In Australia, the building and construction industry is taking significant steps towards the enhancement of environmental performance of the built environment. A large number of world class sustainable buildings have been constructed in recent years, offering researchers and practitioners alike a good opportunity to identify the best practices and real life experiences in delivering high performance buildings. A case study of ONE ONE ONE Eagle Street, a 6 Star Green Star office building in Brisbane, was conducted to investigate the best practice in achieving this “world leader” green office building. The study identified a number of key factors relating to project delivery system, contractor selection method, client’s early commitment, design integration, communication as major contributors to the successful delivery of this project. Additionally, key environmentally sustainable features and their cost implications were explored through in-depth interviews with the main contractor. The findings of this study will shed lights on the successful delivery of sustainable buildings and provide practical implications for different stakeholders.

Autonomous multisensor calibration and closed-loop fusion for SLAM

The vast majority of current robot mapping and navigation systems require specific well-characterized sensors that may require human-supervised calibration and are applicable only in one type of environment. Furthermore, if a sensor degrades in performance, either through damage to itself or changes in environmental conditions, the effect on the mapping system is usually catastrophic. In contrast, the natural world presents robust, reasonably well-characterized solutions to these problems. Using simple movement behaviors and neural learning mechanisms, rats calibrate their sensors for mapping and navigation in an incredibly diverse range of environments and then go on to adapt to sensor damage and changes in the environment over the course of their lifetimes. In this paper, we introduce similar movement-based autonomous calibration techniques that calibrate place recognition and self-motion processes as well as methods for online multisensor weighting and fusion. We present calibration and mapping results from multiple robot platforms and multisensory configurations in an office building, university campus, and forest. With moderate assumptions and almost no prior knowledge of the robot, sensor suite, or environment, the methods enable the bio-inspired RatSLAM system to generate topologically correct maps in the majority of experiments.

Access to essential medicines: Public health and international law

Historically, there have been intense conflicts over the ownership and exploitation of pharmaceutical drugs and diagnostic tests dealing with infectious diseases. Throughout the 1980’s, there was much scientific, legal, and ethical debate about which scientific group should be credited with the discovery of the human immunodeficiency virus, and the invention of the blood test devised to detect antibodies to the virus. In May 1983, Luc Montagnier, Françoise Barré-Sinoussi, and other French scientists from the Pasteur Institute in Paris, published a paper in Science, detailing the discovery of a virus called lymphadenopathy (LAV). A scientific rival, Robert Gallo of the National Cancer Institute, identified the AIDS virus and published his findings in the May 1984 issue of Science. In May 1985, the United States Patent and Trademark Office awarded the American patent for the AIDS blood test to Gallo and the Department of Health and Human Services. In December 1985, the Institut Pasteur sued the Department of Health and Human Services, contending that the French were the first to identify the AIDS virus and to invent the antibody test, and that the American test was dependent upon the French research. In March 1987, an agreement was brokered by President Ronald Reagan and French Prime Minister Jacques Chirac, which resulted in the Department of Health and Human Services and the Institut Pasteur sharing the patent rights to the blood test for AIDS. In 1992, the Federal Office of Research Integrity found that Gallo had committed scientific misconduct, by falsely reporting facts in his 1984 scientific paper. A subsequent investigation by the National Institutes of Health, the United States Congress, and the US attorney-general cleared Gallo of any wrongdoing. In 1994, the United States government and French government renegotiated their agreement regarding the AIDS blood test patent, in order to make the distribution of royalties more equitable... The dispute between Luc Montagnier and Robert Gallo was not an isolated case of scientific rivalry and patent races. It foreshadowed further patent conflicts over research in respect of HIV/AIDS. Michael Kirby, former Justice of the High Court of Australia diagnosed a clash between two distinct schools of philosophy - ‘scientists of the old school... working by serendipity with free sharing of knowledge and research’, and ‘those of the new school who saw the hope of progress as lying in huge investments in scientific experimentation.’ Indeed, the patent race between Robert Gallo and Luc Montagnier has been a precursor to broader trade disputes over access to essential medicines in the 1990s and 2000s. The dispute between Robert Gallo and Luc Montagnier captures in microcosm a number of themes of this book: the fierce competition for intellectual property rights; the clash between sovereign states over access to medicines; the pressing need to defend human rights, particularly the right to health; and the need for new incentives for research and development to combat infectious diseases as both an international and domestic issue.

Overview on different sterilization techniques for baby food

The nutritional quality of the product as well as other quality attributes like microbiological and sensory quality are essential factors in baby food industry, and therefore different alternative sterilizing methods for conventional heating processes are of great interest in this food sector. This report gives an overview on different sterilization techniques for baby food. The report is a part of the work done in work package 3 ”QACCP Analysis Processing: Quality – driven distribution and processing chain analysis“ in the Core Organic ERANET project called Quality analysis of critical control points within the whole food chain and their impact on food quality, safety and health (QACCP). The overall objective of the project is to optimise organic production and processing in order to improve food safety as well as nutritional quality and increase health promoting aspects in consumer products. The approach will be a chain analysis approach which addresses the link between farm and fork and backwards from fork to farm. The objective is to improve product related quality management in farming (towards testing food authenticity) and processing (towards food authenticity and sustainable processes.

Análise dinâmica não-linear de pisos mistos (aço-concreto) submetidos a ações humanas rítmicas.

Atualmente, o crescimento dos problemas de vibrações excessivas sobre pisos mistos (aço-concreto) tem conduzido à necessidade de desenvolvimento de critérios específicos para projetos estruturais submetidos à ação de atividades humanas rítmicas. Com base no desenvolvimento desta dissertação de mestrado, objetiva-se, principalmente, verificar a influência das ligações estruturais (ligações viga-viga), sobre a resposta dinâmica não-linear de pisos mistos (aço-concreto) de edificações, quando submetidos a cargas dinâmicas humanas rítmicas. Deste modo, o carregamento dinâmico empregado para a simulação das atividades humanas sobre o modelo estrutural investigado foi obtido através de testes experimentais com indivíduos praticando atividades rítmicas e não rítmicas. O modelo analisado nesta dissertação corresponde a um piso misto (aço-concreto) com uma área total de 1600m2 e consiste de um ambiente onde serão desenvolvidas atividades de ginástica aeróbica. O sistema estrutural é constituído por lajes de concreto armado apoiadas sobre vigas de aço, simulando o comportamento de um sistema estrutural misto (aço-concreto) com interação total. A metodologia de análise desenvolvida emprega técnicas usuais de discretização presentes no método dos elementos finitos, com base no emprego do programa ANSYS. A modelagem do sistema contempla ligações estruturais do tipo rígidas, semirrígidas e flexíveis. Os valores das acelerações de pico foram comparados com os limites recomendados por normas de projeto, baseando-se em critérios de conforto humano. As conclusões alcançadas ao longo deste trabalho de pesquisa revelam que as ligações estruturais do tipo viga-viga não apresentam influência significativa, no que diz respeito a resposta dinâmica não-linear da estrutura. Por outro lado, as acelerações de pico obtidas com base na análise dinâmica não-linear apresentam valores elevados indicando que o piso misto (aço-concreto) investigado apresenta problemas de vibração excessiva inerentes ao conforto humano.

The load-bearing duct: Biomimicry in structural design

The philosophical aspects of applying the principles of biomimicry are explored in a case study of structural design. Integrating structural engineering with services engineering can be regarded, to some extent, as taking principles from biological systems and applying them to large-scale conceptual design. The end-product discussed herein a so-called load-bearing duct, a functional naturally ventilated multi-storey office building that takes the applied loading efficiently both structurally and cost-effectively giving it the potential to be sustainable throughout its design life.

Natural ventilationwith gradually actuated vents

The transient natural ventilation of an enclosure through vents whose areas vary linearly with time is modelled theoretically. Both displacement and mixing flows are examined and analytical solutions developed. Predictions are presented for the ventilation of a typical office building and compared to existing constant vent area model predictions based on openings of the same average area. The predictions suggest that if the average vent areas are equal in the timedependent and constant area models, the overall time required to ventilate the enclosure is not affected. However, the rate at which heat is removed from the enclosure depends on the initial opening areas and the expansion rates/durations.

A simplified mathematical approach for modelling stack ventilation in multi-compartment buildings

A simple mathematical model of stack ventilation flows in multi-compartment buildings is developed with a view to providing an intuitive understanding of the physical processes governing the movement of air and heat through naturally ventilated buildings. Rules of thumb for preliminary design can be ascertained from a qualitative examination of the governing equations of flow, which elucidate the relationships between 'core' variables - flow rates, air temperatures, heat inputs and building geometry. The model is applied to an example three-storey office building with an inlet plenum and atrium. An examination of the governing equations of flow is used to predict the behaviour of steady flows and to provide a number of preliminary design suggestions. It is shown that control of ventilation flows must be shared between all ventilation openings within the building in order to minimise the disparity in flow rates between storeys, and ensure adequate fresh air supply rates for all occupants. © 2013 Elsevier Ltd.

Energy harvesting system design and optimization for wireless sensor networks

Wireless sensor networks (WSN) are becoming widely adopted for many applications including complicated tasks like building energy management. However, one major concern for WSN technologies is the short lifetime and high maintenance cost due to the limited battery energy. One of the solutions is to scavenge ambient energy, which is then rectified to power the WSN. The objective of this thesis was to investigate the feasibility of an ultra-low energy consumption power management system suitable for harvesting sub-mW photovoltaic and thermoelectric energy to power WSNs. To achieve this goal, energy harvesting system architectures have been analyzed. Detailed analysis of energy storage units (ESU) have led to an innovative ESU solution for the target applications. Battery-less, long-lifetime ESU and its associated power management circuitry, including fast-charge circuit, self-start circuit, output voltage regulation circuit and hybrid ESU, using a combination of super-capacitor and thin film battery, were developed to achieve continuous operation of energy harvester. Low start-up voltage DC/DC converters have been developed for 1mW level thermoelectric energy harvesting. The novel method of altering thermoelectric generator (TEG) configuration in order to match impedance has been verified in this work. Novel maximum power point tracking (MPPT) circuits, exploring the fractional open circuit voltage method, were particularly developed to suit the sub-1mW photovoltaic energy harvesting applications. The MPPT energy model has been developed and verified against both SPICE simulation and implemented prototypes. Both indoor light and thermoelectric energy harvesting methods proposed in this thesis have been implemented into prototype devices. The improved indoor light energy harvester prototype demonstrates 81% MPPT conversion efficiency with 0.5mW input power. This important improvement makes light energy harvesting from small energy sources (i.e. credit card size solar panel in 500lux indoor lighting conditions) a feasible approach. The 50mm × 54mm thermoelectric energy harvester prototype generates 0.95mW when placed on a 60oC heat source with 28% conversion efficiency. Both prototypes can be used to continuously power WSN for building energy management applications in typical office building environment. In addition to the hardware development, a comprehensive system energy model has been developed. This system energy model not only can be used to predict the available and consumed energy based on real-world ambient conditions, but also can be employed to optimize the system design and configuration. This energy model has been verified by indoor photovoltaic energy harvesting system prototypes in long-term deployed experiments.

Civil defence pedagogies and narratives of democracy: disaster education in Germany

‘Disaster education’ is a fledgling area of study in lifelong education. Many countries educate their populations for disasters, to mitigate potential damage and loss of life, as well as contribute to national security. In this paper, which draws on interview data from the German Federal Office for Civil Defence and Disaster Assistance and the Federal Agency for Technical Relief, archival research, analysis of websites and promotional materials as well as relevant academic literature, I examine disaster education and preparedness for national emergencies in Germany. I argue that it is not generally extended to the general public, rather confined to trained experts, decentralised, localised and exclusive. Theorising disaster education as a ‘civil defence pedagogy’ (Preston, 2008), a type of public pedagogy, which contributes to shaping narratives of national identity, I argue that it is unlikely that Germany will develop a more inclusive, universal, formalised, nor high-profile campaign in disaster education in the foreseeable future. This, I suggest, is due to narratives of the German democratic nation state as secure, federal, peaceful and unified, which originated at the founding of West Germany in 1949, and continue to shape contemporary political narratives.

Stellenabbau im Pflegedienst der Krankenhäuser. Eine Analyse der Entwicklung zwischen 1991 und 2005

Hintergrund: Seit Mitte der 1990er Jahre findet ein Stellenabbau in Krankenhäusern statt, von dem insbesondere auch der Pflegedienst betroffen ist. Obwohl die Tatsache seit längerem bekannt ist, fehlt es noch an einer gründlichen Analyse und Aufbereitung der verfügbaren Daten, um sich ein fundiertes Bild über den Umfang, die Entwicklung, Ursachen und Auswirkungen machen zu können. Methoden: Primäre Datengrundlage sind die Daten der Krankenhausstatistik sowie der Gesundheitsausgabenrechnung des Statistisches Bundesamtes. Ergebnisse: Die Analyse führt zu dem Ergebnis, dass zwischen 1995 und 2005 insgesamt ca. 104.000 Vollzeitstellen für nicht-ärztliches Personal in Allgemeinkrankenhäusern abgebaut wurden. Der ärztliche Dienst wurde hingegen um ca. 19.000 Vollkräfte ausgebaut. Im Saldo ergibt dies einen Gesamtstellenabbau von ca. 85.000 Vollkräften. Der größte Teil des Stellenabbaus entfiel mit ca. 44.000 Vollzeitstellen auf den Pflegedienst. Im Jahr 2005 lag die Zahl der Vollkräfte im Pflegedienst der Allgemeinkrankenhäuser um 13,7 % unter dem Wert des Jahres 1995 und sogar noch unter dem Wert des Jahres 1991, als über einen Pflegenotstand in Krankenhäusern gesellschaftlich diskutiert wurde. Eine Analyse der Kostendaten der Allgemeinkrankenhäuser zeigt, dass der Stellenabbau im Pflegedienst nicht allein durch die Budgetdeckelung und Einführung des DRG-Systems erklärt werden kann. Mehr als die Hälfte des Stellenabbaus wäre auf Grund der allgemeinen Budgetentwicklung nicht erforderlich gewesen, sondern erfolgte offenbar, um im Rahmen einer internen Umverteilung Mittel für andere Zwecke freizusetzen. Gewinner der internen Umverteilung war der ärztliche Dienst. Vor dem Hintergrund der Ergebnisse zahlreicher internationaler Studien muss davon ausgegangen werden, dass der Stellenabbau bereits negative Auswirkungen auf die Qualität der Patientenversorgung hat. Die Ergebnisse internationaler Forschung zu diesem Thema weisen darauf hin, dass eine niedrigere Personalbesetzung in Pflegedienst das Risiko erhöht, als Patient im Krankenhaus eine schwerwiegende Komplikation zu erleiden oder sogar zu versterben. Schlussfolgerungen: Es besteht dringender Handlungsbedarf, da sich die Personalbesetzung des Pflegedienstes in Allgemeinkrankenhäusern seit mehr als 10 Jahren in einer Abwärtsspirale befindet und mit weiterem Stellenabbau zu rechnen ist.
