'Homescapes' and identity reformations in Australian multicultural drama

A consideration of identity formation in contemporary Australian multicultural theatre is offered through a re-assessment of the unsettled (and unsettling) constructions of Australia as 'home' in the work of three playwrights. William Yang's Sadness disrupts a localized perception of home, space, and cultural communities to amalgamate two disparate communities (the queer/homosexual community in Sydney and the Asian-Australian, or 'Austasian' community) into a reconfigured Australian identity. Janis Balodis's The Ghosts Trilogy uses many actors who play across the unsettled lines of history, amid numerous voices, homes, and homelands that indicate the enormity of what 'Australia' comes to signify. Noelle Janaczewska's The History of Water constructs a way of locating the self by means of a metaphoric home as each character establishes herself on a psychic plane rather than choosing the strictly physical locations to which she has access. In their interrogations of home and homeland, these plays challenge assumptions regarding identity, disrupt notions of the ultimate ownership of land/culture by anyone, and problematize the idea of settlement as it is currently articulated in Australia.

Oral disease in animals: The Australian perspective. Isolation and characterisation of black-pigmented bacteria from the oral cavity of marsupials

A wide range of animals suffer from periodontal disease. However, there is very little reported on disease and oral micro-biota of Australian animals. Therefore, the oral cavity of 90 marsupials was examined for oral health status. Plaque samples were collected from the subgingival margins using curettes; or swabs. Plaque samples were plated onto. non-selective trypticase soy agar plates, selective trypticase soy agar, non-selective and selective Wilkens Chalgrens, Agar. Plates were incubated in an anaerobic atmosphere and examined after 7-14 days for the presence of black-brown-pigmented colonies. A combination of morphological and biochemical tests were used (colonial morphology, pigmentation, aerobic growth, Gram reaction, fluorescence under long-wave UV light (360 nm), production of catalase, enzymatic activity with fluorogenic substrates and haemagglutination of sheep red cells) to identify these organisms. Black-pigmented bacteria were cultivated from the plaque of 32 animals including six eastern grey kangaroos, a musky rat kangaroo, a whiptail and a red-necked wallaby, 18 koalas, a bandicoot and five brushtail possums. No black-pigmented colonies were cultivated from squirrel or sugar gliders or quokkas or from marsupial mice. The majority of isolates were identified as Porphyromonas gingivalis-like species with the higher prevalence of isolation from the oral cavity of macropods (the kangaroos and wallabies). Oral diseases, such as gingivitis can be found in native Australian animals with older koalas having an increase in disease indicators and black-pigmented bacteria. Non-selective Wilkens Chalgren Agar was the medium of choice for the isolation of black-pigmented bacteria. (C) 2002 Elsevier Science Ltd. All rights reserved.

Control of nitrate recirculation flow in predenitrification systems

The control of the nitrate recirculation flow in a predenitrification system is addressed. An elementary mass balance analysis on the utilisation efficiency of the influent biodegradable COD (bCOD) for nitrate removal indicates that the control problem can be broken down into two parts: maintaining the anoxic zone anoxic (i.e. nitrate is present throughout the anoxic zone) and maximising the usage of influent soluble bCOD for denitrification. Simulation studies using the Simulation Benchmark developed in the European COST program show that both objectives can be achieved by maintaining the nitrate concentration at the outlet of the anoxic zone at around 2 mgN/L. This setpoint appears to be robust towards variations in the influent characteristics and sludge kinetics.

Behaviour of older people admitted for residential respite care

The aim of this pilot study was to determine whether residential respite care is used because of disruptive behaviour displayed by older people. The specific objectives were to 1) characterise older people being admitted for residential respite care, 2) obtain a preliminary estimate of the proportion of older people in residential respite care because of disruptive behaviour, and, 3) examine the relationship between residential respite care and disruptive behaviour. A quantitative approach using a cross-sectional survey was employed. The respite recipients were 35 older people with a mean age of 81.5 years (range 67-96 years). The respite recipients had been admitted for residential respite care to aged care hostels and nursing homes in a provincial city and its surrounding rural area. Nurses rated disruptive behaviour using the Dementia Behavior Disturbance Scale (DBDS). Additional reliability data for the DBDS are provided. The study found that the largest specific group of residential respite care users were widows (31.4%) who lived alone in their own home. The reason for over half (51.4%) of the residential respite admissions was to give a carer a 'break' from the older person. Although a large proportion (80%) of respite recipients were rated as having disruptive behaviour, the proportion of admissions because of disruptive behaviour was much less (28.6%). People with dementia (37.1%) scored significantly higher than people without dementia on the DBDS [F (1,33)=15.57, p

Application of the maximum entropy method to the (2 + 1)D four-fermion model

We investigate spectral functions extracted using the maximum entropy method from correlators measured in lattice simulations of the (2+1)-dimensional four-fermion model. This model is particularly interesting because it has both a chirally broken phase with a rich spectrum of mesonic bound states and a symmetric phase where there are only resonances. In the broken phase we study the elementary fermion, pion, sigma, and massive pseudoscalar meson; our results confirm the Goldstone nature of the π and permit an estimate of the meson binding energy. We have, however, seen no signal of σ→ππ decay as the chiral limit is approached. In the symmetric phase we observe a resonance of nonzero width in qualitative agreement with analytic expectations; in addition the ultraviolet behavior of the spectral functions is consistent with the large nonperturbative anomalous dimension for fermion composite operators expected in this model.

Production of mosquitoes in rainwater tanks and wells on Yorke Island, Torres Strait: Preliminary study

The Torres Strait in northernmost Queensland, Australia, is subject to periodic outbreaks of dengue. A large outbreak of dengue 2 in 1996-97 affected five islands, resulting in 200 confirmed cases. On most of the affected islands, rainwater tanks were a common breeding site for vector mosquitoes. Rainwater tanks, wells and household containers filled with water are the most common breeding sites for dengue mosquitoes (Aedes aegypti), the primary vector of dengue in Queensland. We report on surveys conducted in February 2002 to measure the productivity of rainwater tanks and wells on Yorke Is. (Torres Strait), the first time the productivity of rainwater tanks has been measured in Australia. Of 60 rainwater tanks sampled, 10 had broken screens. Using a sticky emergence trap, 179 adult mosquitoes were collected, consisting of 63 Aedes scutellaris and 116 Culex quinquefasciatus. One unscreened tank produced 177 (99%) of the adults. A plankton net was used to sample 16 wells; 12 positive wells yielded 111 immature (larvae and pupae) mosquitoes, consisting of 57% and 43% Ae. scutellaris and Cx. quinquefasciatus, respectively. The apparent displacement of Ae. aegypti by Ae. scutellaris is discussed. Measures to reduce the likelihood of future dengue outbreaks are recommended.

Asymmetric blasting: a rock mass dependent blast design method

Blasting has been the most frequently used method for rock breakage since black powder was first used to fragment rocks, more than two hundred years ago. This paper is an attempt to reassess standard design techniques used in blasting by providing an alternative approach to blast design. The new approach has been termed asymmetric blasting. Based on providing real time rock recognition through the capacity of measurement while drilling (MWD) techniques, asymmetric blasting is an approach to deal with rock properties as they occur in nature, i.e., randomly and asymmetrically spatially distributed. It is well accepted that performance of basic mining operations, such as excavation and crushing rely on a broken rock mass which has been pre conditioned by the blast. By pre-conditioned we mean well fragmented, sufficiently loose and with adequate muckpile profile. These muckpile characteristics affect loading and hauling [1]. The influence of blasting does not end there. Under the Mine to Mill paradigm, blasting has a significant leverage on downstream operations such as crushing and milling. There is a body of evidence that blasting affects mineral liberation [2]. Thus, the importance of blasting has increased from simply fragmenting and loosing the rock mass, to a broader role that encompasses many aspects of mining, which affects the cost of the end product. A new approach is proposed in this paper which facilitates this trend 'to treat non-homogeneous media (rock mass) in a non-homogeneous manner (an asymmetrical pattern) in order to achieve an optimal result (in terms of muckpile size distribution).' It is postulated there are no logical reasons (besides the current lack of means to infer rock mass properties in the blind zones of the bench and onsite precedents) for drilling a regular blast pattern over a rock mass that is inherently heterogeneous. Real and theoretical examples of such a method are presented.

Development of a quality use of medicines coding system to rate clinical pharmacists' medication review recommendations

Objective: To develop a 'quality use of medicines' coding system for the assessment of pharmacists' medication reviews and to apply it to an appropriate cohort. Method: A 'quality use of medicines' coding system was developed based on findings in the literature. These codes were then applied to 216 (111 intervention, 105 control) veterans' medication profiles by an independent clinical pharmacist who was supported by a clinical pharmacologist with the aim to assess the appropriateness of pharmacy interventions. The profiles were provided for veterans participating in a randomised, controlled trial in private hospitals evaluating the effect of medication review and discharge counselling. The reliability of the coding was tested by two independent clinical pharmacists in a random sample of 23 veterans from the study population. Main outcome measure: Interrater reliability was assessed by applying Cohen's kappa score on aggregated codes. Results: The coding system based on the literature consisted of 19 codes. The results from the three clinical pharmacists suggested that the original coding system had two major problems: (a) a lack of discrimination for certain recommendations e. g. adverse drug reactions, toxicity and mortality may be seen as variations in degree of a single effect and (b) certain codes e. g. essential therapy were in low prevalence. The interrater reliability for an aggregation of all codes into positive, negative and clinically non-significant codes ranged from 0.49-0.58 (good to fair). The interrater reliability increased to 0.72-0.79 (excellent) when all negative codes were excluded. Analysis of the sample of 216 profiles showed that the most prevalent recommendations from the clinical pharmacists were a positive impact in reducing adverse responses (31.9%), an improvement in good clinical pharmacy practice (25.5%) and a positive impact in reducing drug toxicity (11.1%). Most medications were assigned the clinically non-significant code (96.6%). In fact, the interventions led to a statistically significant difference in pharmacist recommendations in the categories; adverse response, toxicity and good clinical pharmacy practice measured by the quality use of medicine coding system. Conclusion: It was possible to use the quality use of medicine coding system to rate the quality and potential health impact of pharmacists' medication reviews, and the system did pick up differences between intervention and control patients. The interrater reliability for the summarised coding system was fair, but a larger sample of medication regimens is needed to assess the non-summarised quality use of medicines coding system.

Alterações na estrutura anatômica da madeira de cavacos de eucalyptus grandis em três condições de desfibramento para a confecção de painéis MDF

A utilização da madeira de eucalipto na confecção de painéis MDF é recente, tornando-se necessário entender as modificações em sua estrutura anatômica durante as etapas do processo industrial, notadamente no desfibramento dos cavacos. Com esse objetivo, neste estudo foram aplicadas três condições diferenciadas de desfibramento dos cavacos, alterando-se (i) o tempo de aquecimento, (ii) as pressões de digestão e de desfibramento e (iii) a energia específica de desfibramento, sendo avaliadas as características anatômicas dos componentes celulares da madeira. O aumento da intensidade de refino dos cavacos de madeira reduziu o comprimento médio das fibras e aumentou o porcentual de fibras quebradas, corroborando as imagens de microscopia eletrônica de varredura, além da diminuição do número dos vasos e de células de parênquima. Essa condição de desfibramento mais intensa promoveu, também, um característico escurecimento da coloração da polpa composta pelos elementos celulares da madeira. A aplicação de variáveis de desfibramento mais brandas aumentou a presença de feixes de fibras e do número de vasos e de parênquima, resultando em uma polpa de coloração mais clara. As alterações das características morfológicas dos componentes celulares da madeira dos cavacos de eucalipto, após o tratamento de desfibramento, relacionaram-se com as etapas do processo operacional e com a qualidade tecnológica dos painéis de fibras MDF.

Angola, jeje e ketu : memórias e identidades em casas e nações de candomblé na Região Metropolitana da Grande Vitória (ES)

Angola, jeje e ketu: Memórias e identidades em casas e nações de candomblé na Região Metropolitana da Grande Vitória (ES), que é o tema desta dissertação, requer adentrar em análises de categorias nativas do povo de santo, e, em seguida, passar a questões teóricas sobre esses temas. Na cidade de Serra encontram-se as quatro casas de santo onde a pesquisa de campo foi realizada com três iyalorixás e um babalorixá, que dividem suas memórias e experiências religiosas compondo um exercício teórico sobre a história e a formação do candomblé no Espírito Santo. Nesse estado, que não é referência dessa religião, a mesma encontra-se em ascensão. A preocupação dos integrantes das comunidades de terreiros é transformar parte das tradições orais em produção escrita. Tendo em vista os processos políticos de reconhecimento legal da diversidade cultural, o debate se deu em torno de hibridização e múltiplas formas de identidade. O universo encantador e mágico do candomblé é composto pelos toques dos atabaques, danças rituais e fé em forças da natureza. Os “filhos da diáspora africana” trazidos para o Brasil eram de várias regiões da África, o que nos permite entender a diversidade cultural que marca esses grupos. Em função do sincretismo entre as próprias religiões de matriz africana e delas com o catolicismo e as doutrinas espiritualistas, essas religiões encontram-se de norte a sul do país. Este encontro de crenças e rituais é tão evidente que já não dizemos religiões “africanas” e sim religiões “afro-brasileiras”. O candomblé, desde o seu surgimento, vem sendo criado e recriado pela transmissão de suas tradições e ritos. A tradição oral nas comunidades de terreiro é um dos elementos demarcadores da construção da sua identidade, a partir de uma organização interna e do aprendizado hierarquicamente transmitido pelos depositários do saber, seguindo uma ordem de senioridade de iniciação, os antigos são detentores dos saberes e segredos. Por ser uma religião iniciática, o aprendizado ocorre permanentemente, em especial o da língua ritual, onde o exercício e o contato levam a transmissão cultural. O povo de santo reconstrói uma ligação com uma comunidade imaginada que remonta a África e desenvolve relações de parentesco ficcional entre os membros das comunidades de terreiro e forma uma família de santo e de axé.

Os ‘intrusos’ e os ‘outros’ quebrando o aquário e mudando os horizontes: as relações de raça e classe na implementação das cotas sociais no processo seletivo para cursos de graduação da UFES

A pesquisa desta tese investiga as mediações das categorias de raça e de classe social no processo de implementação do modelo de cotas sociais da Ufes para ingresso nos cursos de graduação, entre 2006 a 2012, como parte das ações afirmativas dessa universidade. Tal modelo, para incluir a população afro-brasileira no ensino superior do Espírito Santo, respeitou estritamente os critérios de renda e de origem escolar pública, não adotando o critério étnico-racial que contemplaria especificamente os negros e os indígenas. Diante disso, o autor busca sustentar a tese de que, considerando o padrão das relações raciais brasileiras produtor de assimetrias entre grupos com marcas raciais distintas, no caso de negros e brancos, as desigualdades raciais têm na operacionalização do racismo seu mote ofensivo e poderoso, ao mesmo tempo em que a classe social isolada é insuficiente na compreensão e superação do problema racial do Brasil. Portanto, na adoção de políticas de combate às desigualdades raciais no ensino superior, caberia também a utilização de medidas etnicamente referenciadas. Autores como Hall (2008) e Fraser (2006), ao trazerem a dimensão articulada e bifocal das injustiças simbólicas e das injustiças econômicas, permitem entender a complementaridade e as dinâmicas entre ambas, deslocando-se de determinismos classistas que invisibilizam o racismo como instrumento opressor nas relações sociais. Como objetivos específicos, considera: compreender o processo de construção do modelo de cotas da Ufes, para ingresso nos cursos de graduação implementado em 2008, sob a perspectiva do debate da relação entre raça e classe; examinar as políticas de ações afirmativas como respostas às demandas históricas dos afro-brasileiros no contexto da sociedade brasileira; avaliar a posição de professores e alunos de cursos de graduação da Ufes diante do ingresso de alunos cotistas, sobretudo afro-brasileiros e pobres; e investigar a relação das políticas classistas, no caso específico das cotas sociais, na superação das assimetrias raciais. Adota como procedimentos metodológicos a metodologia dialética de pesquisa considerando todas as contradições entre raça e classe no processo de implementação de ações afirmativas na Ufes. Como instrumentos de pesquisa, utiliza entrevistas de professores e alunos cotistas e não cotistas de cursos variados da universidade, assim como documentos referentes à temática. Os resultados apontam para uma “oxigenação” da universidade depois de uma entrada maior de negros e pobres, principalmente nos cursos mais elitizados, pois as cotas operam uma dimensão pedagógica de ampliar a diversidade social na academia, trazendo outras demandas, outras 10 afetividades, outras lógicas de mundo e concepções de sociedade para a única universidade pública do Espírito Santo. Indica que os mecanismos discriminatórios e estigmatizantes interpessoais e institucionais, vividos no contexto das cotas sociais e explícitos na pesquisa, não inviabilizam a importância das ações afirmativas, pois apontam para a universidade repensar e ressignificar seus currículos e ações pedagógicas homogeneizantes no sentido de ampliar a ideia de inclusão e de democratização de seus espaços. Reitera que a raça, em seu viés político e cultural, é operante de forma relacional e independente com a classe social no contexto da produção das assimetrias raciais brasileiras, de maneira que a ação de uma não nega a ação da outra, mesmo na relação entre ambas. Enfatiza a importância do entendimento e da materialidade das ações afirmativas como políticas de reconhecimento que combateriam as desigualdades simbólicas na Ufes. Aponta a relevância das políticas de assistência estudantil, conjugadas às cotas, como políticas de redistribuição econômica, que lidariam com as dificuldades ou ausências materiais dos discentes, principalmente dos cotistas. Conclui que as cotas étnico-raciais nas universidades brasileiras são instrumentos legítimos de luta pela educação, um direito social de oportunidade dos grupos historicamente apartados de princípios constituidores da emancipação, da cidadania, dos direitos humanos, da justiça social, da igualdade e da diferença.

A casa de Porto Seguro : estudo da morfologia da casa portuguesa no Brasil

O estudo da morfologia das casas da rua Dr. Antônio Ricaldi na Cidade Alta de Porto Seguro no estado da Bahia tem como objetivo esclarecer os limites da influência da arquitetura portuguesa na construção das casas do sítio histórico referido tombado pelo IPHAN desde 1973. Foi realizado um estudo comparativo da tipologia das casas do mesmo conjunto arquitetônico e através da referência teórica da história da arquitetura portuguesa e da evolução urbana nos primeiros núcleos populacionais no Brasil é apresentado a aproximação tipológica portuguesa mais semelhante as casas do conjunto estudado em Porto Seguro. A pesquisa de campo foi realizada na Cidade Alta de Porto Seguro de 2012 à 2014. O recorte escolhido para o estudo foram 25 casas da rua Dr. Antônio Ricaldi, com ênfase na casa de Edson Ramalho Jr número 65; por sua relevância na conservação da tipologia como um exemplo mais semelhante a uma casa vernácula1 de porta e janela análoga às primitivas construções desse sítio. Esta casa tem um destaque especial por sua localização privilegiada dentro do sítio e como um ponto de referência da história da arquitetura portuguesa no Brasil. O uso da casa como museu: Casa Histórica aconteceu de 1996 à 2004 como um modelo capaz de elencar projetos culturais e educativos para a Cidade Alta, visando o uso, conservação, difusão e sustentabilidade do patrimônio histórico e cultural. A documentação levantada com a pesquisa é relevante para o estímulo da arquitetura vernácula e uma referência à memória da arquitetura portuguesa no Brasil. Fomentando novos estudos e empreendimentos sobre o tema, para um sítio histórico pouco estudado, em uma região de grande visitação turística no Brasil mas, sem projetos que visem a devida conservação, apresentação e uso desse sítio de forma sustentável

A Platform to Emulate Ambient Assisted Living Environments

According to the opinion of clinicians, emerging medical conditions can be timely detected by observing changes in the activities of daily living and/or in the physiological signals of a person. To accomplish such purpose, it is necessary to properly monitor both the person’s physiological signals as well as the home environment with sensing technology. Wireless sensor networks (WSNs) are a promising technology for this support. After receiving the data from the sensor nodes, a computer processes the data and extracts information to detect any abnormality. The computer runs algorithms that should have been previously developed and tested in real homes or in living-labs. However, these installations (and volunteers) may not be easily available. In order to get around that difficulty, this paper suggests the making of a physical model to emulate basic actions of a user at home, thus giving autonomy to researchers wanting to test the performance of their algorithms. This paper also studies some data communication issues in mobile WSNs namely how the orientation of the sensor nodes in the body affects the received signal strength, as well as retransmission aspects of a TDMA-based MAC protocol in the data recovery process.

Conceptual design of a conveyer system for supporting basic quality of life of bedridden elderly people

With the increasing number of aged people, especially in developed countries, Ambient Assisted Living solutions have become an important subject to be explored and developed. Currently, as specialized Institutions in geriatric care cannot cope with the increasing requests for support of quality of life, patients have to remain at their homes having as caregiver the other member of the couple or a member of close family. A solution for supporting the caregiver, during assisting the bedridden person with some basic tasks as eating, taking a bath and/or hygiene care is of utmost importance. This paper presents an approach for supporting the caregiver in moving and repositioning the bedridden elderly people (BEP) with the assistance of a mechanical system conveyer. The conceptual design of the mechanical system must be devoted to assist the caregiver in the handling and repositioning of the BEP. The proposed mechatronic system must, ideally, minimize the system's handling complexity, reduce the number of caregivers and the amount of spended and needed effort.

Conceptual design of a mechatronic system for supporting basic quality of life of bedridden elderly people

Ambient Assisted Living is an important subject to be explored and developed, especially in developed countries, due to the increasing number of aged people. In this context the development of mechatronic support systems for bedridden elderly people (BEP) living in their homes is essential in order to support independence, autonomy and improve their quality of life. Some basic tasks as eating, taking a bath and/or hygiene cares become difficult to execute, regarding that often the main caregiver is the other element of the aged couple (husband or wife). This paper presents the conceptual design of a mechanical system especially devoted to assist the caregiver in the handling and repositioning of the BEP. Issues as reducing the number of caregivers, to only one, and reducing the system's handling complexity (because most of the time it will be used by an aged person) are considered. The expertise obtained from the visits to rehabilitation centers and hospitals, and from working meetings, are considered in the development of the proposed mechatronic system.
