A story about being engaged in research : buzzing bees, small business and Australian unfair dismissal laws

Protection for employees from unfair dismissal (UFD) has been around in Australia under various guises for 30 years or so (Chapman, 2006). Labour standards, and particularly ILO Convention 158 (Convention Concerning Termination of Employment at the Initiative of the Employer 1982), underpin the adoption of a particular form of federal statutory UFD regime which first appeared in the 1993 reforms to the Industrial Relations Act 1998 (Commonwealth). Its existence, however, has not been uncontroversial, and the meaning, operation, scope and remedies have attracted attention over time. In fact, the first reforms to the federal UFD regime were undertaken under the Keating Labor government three months after they were enacted (Chapman, ibid.). Further reforms were made by the incoming Howard Liberal-national coalition government through the Workplace Relations Act 1996 (Commonwealth) (WRA), and arguably these reforms continued down the ‘contraction’ path (ibid.).

From the buzzing in Turing’s head to machine intelligence contests

This paper presents an analysis of three major contests for machine intelligence. We conclude that a new era for Turing’s test requires a fillip in the guise of a committed sponsor, not unlike DARPA, funders of the successful 2007 Urban Challenge.

Street computing workshop 2009

The Street Computing workshop, held in conjunction with OZCHI 2009, solicits papers discussing new research directions, early research results, works-in-progress and critical surveys of prior research work in the areas of ubiquitous computing and interaction design for urban environments. Urban spaces have unique characteristics. Typically, they are densely populated, buzzing with life twenty-four hours a day, seven days a week. These traits afford many opportunities, but they also present many challenges: traffic jams, smog and pollution, stress placed on public services, and more. Computing technology, particularly the kind that can be placed in the hands of citizens, holds much promise in combating some of these challenges. Yet, computation is not merely a tool for overcoming challenges; rather, when embedded appropriately in our everyday lives, it becomes a tool of opportunity, for shaping how our cities evolve, for enabling us to interact with our city and its people in new ways, and for uncovering useful, but hidden relationships and correlations between elements of the city. The increasing availability of an urban computing infrastructure has lead to new and exciting ways inhabitants can interact with their city. This includes interaction with a wide range of services (e.g. public transport, public services), conceptual representations of the city (e.g. local weather and traffic conditions), the availability of a variety of shared and personal displays (e.g. public, ambient, mobile) and the use of different interaction modes (e.g. tangible, gesture-based, token-based). This workshop solicits papers that address the above themes in some way. We encourage researchers to submit work that deals with challenges and possibilities that the availability of urban computing infrastructure such as sensors and middleware for sensor networks pose. This includes new and innovative ways of interacting with and within urban environments; user experience design and participatory design approaches for urban environments; social aspects of urban computing; and other related areas.

Urban informatics

The increasing ubiquity of digital technology, internet ser-vices and social media in our everyday lives allows for a seamless transitioning between the visible and the invisible infrastructure of cities: road systems, building complexes, information and communication technology, and people networks create a buzzing environment that is alive and exciting. Driven by curiosity, initiative and interdiscipli-nary exchange, the Urban Informatics Research Lab at Queensland University of Technology (QUT), Brisbane, Australia, is an emerging cluster of people interested in research and development at the intersection of people, place and technology with a focus on cities, locative media and mobile technology. This paper seeks to define, for the first time, what we mean by ‘urban informatics’ and outline its significance as a field of study today. It describes the relevant background and trends in each of the areas of peo-ple, place and technology, and highlights the relevance of urban informatics to the concerns and evolving challenges of CSCW. We then position our work in academia juxta-posed with related research concentrations and labels, fol-lowed by a discussion of disciplinary influences. The paper concludes with an exposé of the three current research themes of the lab around augmented urban spaces, urban narratives, and environmental sustainability in order to illustrate specific cases and methods, and to draw out distinctions that our affiliation with the Creative Industries Faculty affords.

Urban informatics, ubiquitous computing and social media for healthy cities

The increasing ubiquity of digital technology, internet services and location-aware applications in our everyday lives allows for a seamless transitioning between the visible and the invisible infrastructure of cities: road systems, building complexes, information and communication technology, and people networks create a buzzing environment that is alive and exciting. Driven by curiosity, initiative and interdisciplinary exchange, the Urban Informatics Research Lab at Queensland University of Technology (QUT), Brisbane, Australia, is an emerging cluster of people interested in research and development at the intersection of people, place and technology with a focus on cities, locative media and mobile technology. This paper introduces urban informatics as a transdisciplinary practice across people, place and technology that can aid local governments, urban designers and planners in creating responsive and inclusive urban spaces and nurturing healthy cities. Three challenges are being discussed. First, people, and the challenge of creativity explores the opportunities and challenges of urban informatics that can lead to the design and development of new tools, methods and applications fostering participation, the democratisation of knowledge, and new creative practices. Second, technology, and the challenge of innovation examines how urban informatics can be applied to support user-led innovation with a view to promote entrepreneurial ideas and creative industries. Third, place, and the challenge of engagement discusses the potential to establish places within cities that are dedicated to place-based applications of urban informatics with a view to deliver community and civic engagement strategies.

From Synapse to Self: Spikes, Synchrony, and Attentive Learning by Laminar Thalamocortical Circuits

How do our brains transform the "blooming buzzing confusion" of daily experience into a coherent sense of self that can learn and selectively attend to important information? How do local signals at multiple processing stages, none of which has a global view of brain dynamics or behavioral outcomes, trigger learning at multiple synaptic sites when appropriate, and prevent learning when inappropriate, to achieve useful behavioral goals in a continually changing world? How does the brain allow synaptic plasticity at a remarkably rapid rate, as anyone who has gone to an exciting movie is readily aware, yet also protect useful memories from catastrophic forgetting? A neural model provides a unified answer by explaining and quantitatively simulating data about single cell biophysics and neurophysiology, laminar neuroanatomy, aggregate cell recordings (current-source densities, local field potentials), large-scale oscillations (beta, gamma), and spike-timing dependent plasticity, and functionally linking them all to cognitive information processing requirements.

3D haptic needle insertion simulator utilising an agent based spherical voxel model

This paper describes a technique for the real-time modeling of deformable tissue. Specifically geared towards needle insertion simulation, the low computational requirements of the model enable highly accurate haptic feedback to a user without introducing noticeable time delay or buzzing generally associated with haptic surgery simulation. Using a spherical voxel array combined with aspects of computational geometry and agent communication and interaction principals, the model is capable of providing haptic update rates of over 1000Hz with real-time visual feedback. Iterating through over 1000 voxels per millisecond to determine collision and haptic response while making use of Vieta’s Theorem for extraneous force culling.

The hive

The hive - busily buzzing about the square like a hive of bees, students exchanged acts of happiness and kindness, through these exchanges the students collect a series of data they display like an expanding collage - creating a domino effect of positivity.

Entomofauna visitante das flores de Cassia spectabilis (L.) D C. (Leguminosae)

Realizaram-se estudos sobre sistemas de reprodução de Cassia spectabilis (L.) D C. (Leguminosae) observando-se a diversidade, freqüência e constância dos insetos visitantes em diferentes horários. Também testou-se a influência dos fatores ambientais em relação às visitas. Os resultados de polinização manual sugerem que C. spectabilis é autocompatível, porém, a xenogamia é o sistema de reprodução predominante. As inflorescências foram visitadas por uma grande quantidade de insetos, havendo predominância de abelhas. O horário de maior ocorrência dos insetos nas flores de C. spectabilis foi das 8 às 14 h e de menor ocorrência entre 7 e 8 h e das 17 às 18 h. Quanto ao comportamento dos insetos em relação à flor de C. spectabilis, observou-se que Xylocopa frontalis Olivier, X. suspecta Camargo & Moure, Bombus morio Swederus e Centris scopipes Friese possuem comportamento e morfologia adequados aos polinizadores legítimos; C. similis F., Oxaea flavescens Klug e Epicharis rustica flava Cockerell foram considerados polinizadores ocasionais. Pseudaugochloropsis graminea (F.), Tetragonisca angustula Latreille e A. mellifera L. foram considerados pilhadores. A polinização por vibração é o método usado pelas abelhas para coleta de pólen.

Impactos na qualidade da energia elétrica provenientes do rápido crescimento da demanda no Sudeste do Estado do Pará

Nos últimos anos, o desenvolvimento sócio econômico da Região Sudeste do Estado do Pará, tem sido causado principalmente pela exploração e processamento industrial de minérios, que agregado ao crescimento populacional, tem gerado grande evolução na demanda do consumo de energia elétrica, devido à instalação cada vez mais crescente de novas cargas industriais, comerciais, residenciais e rurais monofásicas. Todo esse aumento de carga já está impactando diretamente o desempenho das subestações distribuidoras da Concessionária de Energia Elétrica, no que tange a manifestação de distúrbios de regime permanente causados por harmônicas, tais como zumbidos em transformador de força e rompimento de condutores de média tensão. Estes distúrbios são apresentado em um estudo de caso envolvendo as Subestações (SE´s) Itacaiúnas e Itupiranga. Para comprovar a nocividade desses distúrbios nessas SE´s, foram realizadas campanhas de medição para obtenção de resultados práticos e, então, executadas simulações envolvendo estudos de curtocircuito, fluxo de carga e propagação de harmônicos, de forma a se obter um diagnóstico analítico sobre as situações encontradas e assim, ser possível emitir recomendações para a mitigação dos problemas detectados. Este trabalho será de grande valia à Concessionária de Energia Elétrica, podendo ser tomado como uma das referências para estudos de qualidade de energia elétrica, em outras subestações, além de dar embasamento experimental às futuras cobranças da ANEEL, com relação à implantação dos Procedimentos de Distribuição de Energia Elétrica no Sistema Elétrico Nacional (PRODIST).

Les paysages sous-marins du Québec : le cas de la découverte, de la mise en valeur et de la reconnaissance du jardin des Escoumins

Cette recherche exploratoire examine le concept émergent de « paysage sous-marin » présenté sous la forme d’une étude cas — celui du jardin des Escoumins — situé dans le parc marin du Saguenay – Saint-Laurent, au Québec. On constate, depuis les dernières décennies, deux complications qui s’interposent au concept de paysage sous-marin puisque d’une part on examine un divorce entre les Québécois et le fleuve Saint-Laurent puis d’une autre on observe l’omission fréquente de sa reconnaissance dans la littérature géographique. En somme, deux questions de recherche en découlent, soit : Quels sont les procédés employés pendant le XXe et XXIe siècle dans la construction des paysages sous-marins au Québec ? et : Quel est le rôle des différents acteurs, et plus précisément celui des plongeurs, dans la mise en valeur et la reconnaissance du paysage sous-marin des Escoumins ? La recherche a été accomplie à travers une revue extensive de la littérature régionale et mondiale portant sur ce concept atypique. Par la suite, une enquête de 35 questions soumises à un échantillon de 73 plongeurs québécois a été analysée, ainsi que sept entrevues semi-dirigées avec des acteurs clefs du domaine. Puis, l’étude et la cartographie des relations spatiales entre les plongeurs et les lieux de prédilection de leur activité ont été réalisés. Les résultats démontrent des interrelations complexes entre les caractéristiques de construction de ces paysages sublimes (le territoire, la nordicité, la pratique d’une activité de loisir, la technologie, l’esthétisme ainsi que l’essor économique et touristique) et les acteurs clefs. Comme la « découverte » des paysages alpins au XVIIIe siècle en Europe, la lente mise en valeur des paysages sous-marins au Québec est causée par la marginalité des lieux. Ainsi, la reconnaissance des paysages subaquatiques est en pleine effervescence au Québec et l’intégration de ce concept en aménagement et en planification touristiques devient capitale.
