Koala mortality on roads in south-east Queensland: the koala speed-zone trial

In 1995, the Queensland Parks and Wildlife Service, the Queensland Department of Main Roads and Redland Shire Council initiated the Koala Speed Zone Trial in the Koala Coast, south-east Queensland. The aim of the trial was to assess the effect of differential speed signs on the number of koalas ( Phascolarctos cinereus) hit by vehicles in the Koala Coast from 1995 to 1999. On the basis of information collected by the Queensland Parks and Wildlife Service 1407 koalas were hit by vehicles in the Koala Coast during the five-year study ( mean 281 koalas per year, range 251 - 315). Monitoring of vehicle speeds by the Queensland Department of Main Roads suggested that there was no significant reduction in vehicle speed during the trial period from August to December. Consequently, there was no evidence to suggest that a reduction in the number of koalas hit by vehicles occurred during the trial. Approximately 70% of koalas were hit on arterial and sub-arterial roads and approximately 83% did not survive. The location of each koala hit was recorded and the signed speed limit of the road was noted. Most koalas that were hit by vehicles were young healthy males. Pooling of data on koala collisions and road speed limits suggested that the proportion of koalas that survived being hit by vehicles was slightly higher on roads with lower speed limits. However, vehicle speed was not the only factor that affected the number of koalas hit by vehicles. It is suggested that habitat destruction, koala density and traffic volume also contribute to road-associated koala mortality in the Koala Coast.

The over-production of US sports and the new International Division of Cultural Labor

This article focuses on how US professional sports utilize the New International Division of Cultural Labor to supplement an overly costly local labor pool and over-supplied local market. We argue that while the classic problem of over-production is slowly eroding the sealed-off nature of US culture, the forces of its hyper-protectionist capitalism continue to characterize sports, precluding equal exchange.

Dead man: um encontro com o passado desconhecido

O filme de Jim Jarmusch, Dead man, aparentemente um western, excede as tradicionais fronteiras do gênero, abordando ambivalência, papéis obscuros em um ambiente situado entre os tempos da fundação da nação americana e o sucesso da civilização. Isso mostra um mundo em transformação, onde a mudança está acontecendo sem ser administrada. O filme é uma provocação pela aderência aos tradicionais filmes de western. Mas, olhando mais de perto, esse mundo oferece um surpreendente insight em relação à dinâmica envolvida nos processos de mudança que também se seguem às fusões ou aquisições no mundo contemporâneo dos negócios. O charme de usar o filme como uma metáfora é ao menos ambíguo. A interpretação realizada com a ajuda de Lyotard e Baudrillard revela uma dinâmica duplamente crítica, na qual o novo proprietário bem sucedido, após a aquisição, não é necessariamente quem controla o jogo. Além disso, o uso de um filme que está fora do mainstream oferece um argumento, do âmago de um tópico central de management, que não faz parte do mainstream.

Utilization of remote experimentation in mobile devices for education

In this paper the authors intend to demonstrate the utilization of remote experimentation (RE) using mobile computational devices in the Science areas of the elementary school, with the purpose to develop practices that will help in the assimilation process of the subjects taught in classroom seeking to interlink them with the daily students? activities. Allying mobility with RE we intend to minimize the space-temporal barrier giving more availability and speed in the information access. The implemented architecture utilizes technologies and freely distributed softwares with open code resources besides remote experiments developed in the Laboratory of Remote Experimentation (RExLab) of Federal University of Santa Catarina (UFSC), in Brazil, through the physical computation platform of the ?open hardware of construction of our own. The utilization of open code computational tools and the integration of hardware to the 3D virtual worlds, accessible through mobile devices, give to the project an innovative face with a high potential for reproducibility and reusability.

Programa de controle de surto de escorpião Tityus serrulatus, Lutz e Mello 1922, no município de Aparecida, SP (Scorpiones, Buthidae)

Os autores propuseram para o município de Aparecida, vale do Rio Paraíba, SP, região endêmica do Tityus serrulatus, um programa de controle do escorpionismo. Foram estudados a presença de focos do escorpião no campo e na cidade, as alterações ambientais periféricas à zona urbana e os novos ambientes de procriação e dispersão destes artrópodes. Além disso, foram avaliados os problemas básicos de infra-estrutura, tais como o acondicionamento e a coleta do lixo urbano público e domiciliar, o saneamento básico (esgotos e galerias pluviais) e a situação dos terrenos baldios e as construções da zona urbana. Após estudo epidemiológico, foram propostas medidas educativas, que constaram da confecção e distribuição de folhetos, de mutirões de limpeza, de visitas domiciliares e do engajamento de professores e alunos da rede de ensino pública e privada na campanha. Nos locais onde existiam focos de alto risco, em especial nas pré-escolas, foi proposto o emprego do controle químico. Dentro das normas sanitárias vigentes para a zona urbana, foi proposto ainda, o uso de predadores naturais no combate. Os autores concluem que as ações devem ser integradas e continuadas de forma ininterrupta por vários anos e propõem ação conjunta com a campanha da dengue. A instituição de uma semana por ano dedicada ao estudo do escorpionismo nas escolas dos municípios onde ocorre o problema seria uma medida educativa que viria contribuir sobremaneira para a prevenção dos acidentes e controle do escorpionismo.

Analysis and visualization of energy use for university campus

The reduction of greenhouse gas emissions is one of the big global challenges for the next decades due to its severe impact on the atmosphere that leads to a change in the climate and other environmental factors. One of the main sources of greenhouse gas is energy consumption, therefore a number of initiatives and calls for awareness and sustainability in energy use are issued among different types of institutional and organizations. The European Council adopted in 2007 energy and climate change objectives for 20% improvement until 2020. All European countries are required to use energy with more efficiency. Several steps could be conducted for energy reduction: understanding the buildings behavior through time, revealing the factors that influence the consumption, applying the right measurement for reduction and sustainability, visualizing the hidden connection between our daily habits impacts on the natural world and promoting to more sustainable life. Researchers have suggested that feedback visualization can effectively encourage conservation with energy reduction rate of 18%. Furthermore, researchers have contributed to the identification process of a set of factors which are very likely to influence consumption. Such as occupancy level, occupants behavior, environmental conditions, building thermal envelope, climate zones, etc. Nowadays, the amount of energy consumption at the university campuses are huge and it needs great effort to meet the reduction requested by European Council as well as the cost reduction. Thus, the present study was performed on the university buildings as a use case to: a. Investigate the most dynamic influence factors on energy consumption in campus; b. Implement prediction model for electricity consumption using different techniques, such as the traditional regression way and the alternative machine learning techniques; and c. Assist energy management by providing a real time energy feedback and visualization in campus for more awareness and better decision making. This methodology is implemented to the use case of University Jaume I (UJI), located in Castellon, Spain.

The assessment, management and ecological significance of Irish hedgerows

The vast network of hedges in Ireland provide habitats of great importance to the wildlife of the country, yet surprisingly enough, only very limited survey work has been carried out on our hedgerows in the past. Now with the implementation of the new Rural Environmental Protection Scheme, farmers will be paid to manage their hedgerows in such a way as to make them into increasingly attractive wildlife habitats. However, hedgerow management expertise seems to be somewhat lacking in Ireland and we must draw upon the knowledge of our neighbours in the E.U. where quite an amount of research has been carried out on this subject. The aim of this study is to present the relevant aspects of the research for the benefit of the people who will be involved in the administration of the Rural Environmental Protection Scheme and to anyone else involved in hedgerow management.

Are two tax rates better than one?

Abstract: Should two–band income taxes be progressive given a general income distribution? We provide a negative answer under utilitarian and max-min welfare functions. While this result clarifies some ambiguities in the literature, it does not rule out progressive taxes in general. If we maximize total or weighted utility of the poor, as often intended by the society, progressive taxes can be justified, especially when the ‘rich’ are very rich. Under these objectives we obtain new necessary conditions for progressive taxes, which only depend on aggregate features of income distributions. The validity of these conditions is examined using plausible income distributions.

An optimized method for establishing high purity murine CD8+ T cell cultures.

Establishing CD8(+) T cell cultures has been empirical and the published methods have been largely individual laboratory based. In this study, we optimized culturing conditions and show that IL-2 concentration is the most critical factor for the success of establishing CD8(+) T cell cultures. High IL-2 concentration encouraged T cells to non-specifically proliferate, express a B cell marker, B220, and undergo apoptosis. These cells also lose typical irregular T cell morphology and are incapable of sustaining long-term cultures. Using tetramer and intracellular cytokine assessments, we further demonstrated that many antigen-specific T cells have been rendered nonfunctional when expanded under high IL-2 concentration. When IL-2 is used in the correct range, B220-mediated cell depletion greatly enhanced the success rate of such T cell cultures.
