Análise de torres de transmissão submetidas a cargas dinâmicas
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro Tecnológico. Programa de Pós-Graduação em Engenharia Civil.Torres de transmissão de energia são de grande importância para o abastecimento elétrico de um país, pois são elas que suportam os cabos que transmitem a energia. A ruptura ou mesmo a danificação destas estruturas pode ter conseqüências significativas para a economia local. No Brasil o principal carregamento que incide sobre uma linha de transmissão de energia é causado pela ação do vento. A norma brasileira NBR 6123 tem um mapa de isopletas do vento, com a indicação da velocidade média para um período de recorrência de 50 anos a uma altura de 10 metros do solo. Como usualmente o período fundamental da estrutura de torres de transmissão é inferior a 1 s, a maioria das normas permite que seu dimensionamento seja realizado para cargas estáticas equivalentes, obtidas a partir da velocidade média do vento e alguns parâmetros adicionais, função da localização geográfica da torre, sua altura e a área efetiva de incidência do vento. No entanto não são raros os eventos de colapso de torres de transmissão de energia no Brasil, e além disso, a ocorrência de fortes rajadas e ciclones vêm aumentando no país nos últimos anos. Justificase assim a necessidade de uma verificação mais apurada do projeto de torres de transmissão, neste caso sob a ação dinâmica do vento. Escolheu-se para este trabalho uma torre de transmissão típica, situada no sul do Brasil. A estrutura da torre é modelada por elementos de pórtico 3D, sendo consideradas rígidas as ligações das barras principais e rotuladas as ligações de barras secundárias. As análises dinâmicas da ação do vento são realizadas no domínio do tempo, sendo a componente turbulenta do vento obtida a partir dos espectros de Davenport e Kaimal e série de Fourier. Outro caso de carregamento considerado neste tipo de torre é a carga que simula a ruptura de um ou mais cabos de energia, que são fixados à torre para manter suas catenárias com as alturas de segurança nos vãos adjacentes. A ruptura de um cabo em um dos lados da torre pode ser simulada aplicando-se uma força no suporte, no lado contrário. Esta força pode ser aplicada estática ou dinamicamente e pode ser decomposta em duas parcelas: uma devida ao peso do cabo e a outra a tração no cabo, utilizada para o seu correto posicionamento na linha de transmissão. Admite-se nas análises que a torre tem comportamento elástico-linear, e utiliza-se o método da superposição modal para resolver as equações de movimento da estrutura. Conclusões e recomendações são apresentadas no final do trabalho
Aboriginal and Torres Strait Islander People and dementia: a review of the research
No full textThis report outlines the prevalence of dementia and modifiable risk factors in Aboriginal and Torres Strait Islander communities.
Executive summary
The high rate of dementia in Aboriginal and Torres Strait Islander communities requires urgent attention. Aboriginal and Torres Strait Islander people experience dementia at an earlier age then the general population and this, combined with the steadily growing number of older Aboriginal and Torres Strait Islander people, will result in the number of people effected by dementia growing significantly in the coming years.
Although higher rates of dementia have been reported in Aboriginal and Torres Strait Islander people, the disease is often overlooked by Aboriginal and Torres Strait Islander communities, health workers and service providers. Geographical constraints in the provision of services, a lack of education and awareness in communities and by health workers and the prevalence of other chronic diseases have all posed considerable barriers to the recognition of dementia as an emerging health issue.
This paper includes the following recommendations to ensure that Aboriginal and Torres Strait Islander people, family members and communities have access to awareness, information, and appropriate support services for people with dementia
El keynesianismo desde la óptica de los países atrasados: su adaptación por Manuel de Torres a la Economía española
No full textEditada en la Fundación SEPIEl siguiente trabajo se propone estudiar la introducción del keynesianismo
en España a través de los escritos de Manuel de Torres, probablemente el
más activo de los economistas que adoptaron de una u otra forma la nueva
doctrina en la posguerra. Dada la escasez en España de una reflexión teórica
original, el artículo prestará especial atención a la adaptación que realiza Torres
de las ideas keynesianas al contexto de la economía española. En particular,
las ideas keynesianas contribuyeron decisivamente a sustituir la vía agraria
defendida por Torres como camino de desarrollo de la economía española
por el industrialismo que sostiene en la posguerra. El articulo ofrece las claves
de esta evolución doctrinal y reivindica el papel de las ideas económicas como
poderoso instrumento de transformación.The main aim of the article is to analyse the introduction of keynesianism
into Spain through the Manuel de Torres' works, the most active proponent
of the new doctrine duríng the forties and fifties. The article focus on the
adaptation to the Spanish context of the Keynes's ideas by Manuel de Torres.
In particular, Keynesianism contrihuted to replace the agrarian ideas defended
by Torres in the thirties by a new interest in industrial development during
the 40's and 50's. Thus, the article provides an explanation of Torres' doctrinal
evolution and vindicates the role played by the economic ideas as an instrument
of transformation. These ideas contributed to change the Torres perception
of the Spanish economic reality.Publicad

Aboriginal and Torres Strait Islander art economies project: literature review
No full textExecutive summary: This literature review surveys writing about the Aboriginal and Torres Strait Islander art and craft sector of remote Australia. The review has been compiled as a foundational text for the ‘Aboriginal and Torres Strait Islander Art Economies’ research project being undertaken by the CRC for Remote Economic Participation (CRC-REP). The Art Economies Project (AEP) is a unique opportunity to investigate, analyse and enhance key points of exchange within the sector, many of which are poorly understood, under-researched and characterised by different kinds of fragility or instability.The sector is a significant contributor to the cultural and social life of Australia and simultaneously creates important enterprise and employment opportunities for remote-area Aboriginal and Torres Strait Islander people. Broadly, Aboriginal and Torres Strait Islander people are more likely to be employed in visual arts and crafts occupations as their main job (52%) than non-Aboriginal and Torres Strait Islander people (9.7%) (Commonwealth of Australia 2012), and investments in Aboriginal and Torres Strait Islander arts centres generate positive financial returns to artists, calculated at a ratio of approximately 1:5 (Commonwealth of Australia 2007a).This review is linked to the primary zones in which AEP research will take place, presenting the current understanding and gaps in each of the six areas of interest: the scope and scale of the sector; the business of remote-area art centres; artists and art business outside of art centres; marketing and consumer dynamics; remote area human resources; and e-commerce and licensing.Publications describing the aesthetic, social, cultural and economic dynamics of the Aboriginal and Torres Strait Islander art economy have been generated by a broad range of people, from economists to anthropologists, art historians to art dealers. This diversity creates challenges in assembling an encompassing literature review. Despite the range of material, however, it is also clear that there are sizeable and important gaps in knowledge about the art economy. These gaps range from understanding the size of, and financial flows within, the sector through to the barriers for remote enterprise and the opportunities for (and obstacles within) new marketing and business models. In contrast to the knowledge gaps about the commercial forces at work is a considerable body of research into the social and cultural worlds of remote area art and artists.Recent years have seen a major contraction in the art economy. The Australian Bureau of Statistics reports a 52.1% reduction in sales in remote art centres (Commonwealth of Australia 2012:2) since 2007, which accords with other anecdotal industry information as to the fragility within the sector. Understanding this fragility and the potential for expanding the success of the art economy, lie at the nucleus of the AEP’s research work.Authors:Tim Acker: Curtin University Dr Lisa Stefanoff: University of South Australia; Dr Alice Woodhead: Southern Cross Universit
Cancer in Aboriginal and Torres Strait Islander peoples of Australia: an overview
No full textThis report brings together the most up-to-date data available from a wide range of sources to describe the status of cancer in Aboriginal and Torres Strait Islander people in Australia.SummaryCancer in Aboriginal and Torres Strait Islander peoples of Australia: an overview provides a summary of statistics on cancer in Aboriginal and Torres Strait Islander peoples of Australia.Cancer incidence and mortality rates are higher for Indigenous Australians In 2004-2008, Indigenous Australians had a higher rate of new cancer cases diagnosed than non-Indigenous Australians (461 compared with 434 per 100,000) using age-standardised data. Lung cancer was the most commonly diagnosed cancer for Indigenous Australians. In 2007-2011, the age-standardised cancer mortality rate was higher for Indigenous Australians than for non-Indigenous Australians (252 compared with 172 per 100,000). Lung cancer was the leading cause of cancer death for Indigenous Australians.Cancer survival is lower for Indigenous Australians Indigenous Australians diagnosed with cancer between 1999 and 2007 had a 40% chance of surviving for at least 5 years, which was lower than non-Indigenous Australians (52%).Fewer cancer-related hospitalisations occurred for Indigenous Australians From 2006-07 to 2010-11, Indigenous Australians were less likely to be hospitalised for a principal diagnosis of cancer compared with other Australians (113 compared with 170 per 10,000), although they had longer hospitalisations than other Australians (9.6 compared with 7.7 days on average).Higher prevalence of cancer-related modifiable risk factors Aboriginal and Torres Strait Islander peoples have higher rates of certain lifestyle risk factors, which can partly explain some cancer incidence and mortality patterns such as: Liver cancer: Indigenous Australians are 3 times as likely to develop, and 3.3 times as likely to die from liver cancer and had a lower chance of surviving another 1 year (21% compared with 33%) than non-Indigenous Australians. Higher rates of risky alcohol consumption and higher prevalence of hepatitis B infection in this population group may be contributing factors.Cervical cancer: Indigenous females are 2.8 times as likely to develop and 3.9 times as likely to die from cervical cancer and had a lower chance of surviving another 5 years (51% compared with 67%) than non-Indigenous females. A contributing factor in the higher rates in Indigenous females could be lower rates of cervical screening for this population group.Lung cancer: Indigenous Australians are 1.9 times as likely to develop and die from lung cancer as non-Indigenous Australians. A contributing factor may be the higher prevalence of smoking among Indigenous Australians than non-Indigenous Australians (38% compared with 18%).Breast cancer in females: Indigenous females diagnosed with breast cancer in 2003-2007 had a 100% higher risk of dying from any cause by 2010 than non-Indigenous females. The poorer prognosis could be at least partly explained by the lower participation of Indigenous females in breast cancer screening (36%) than non-Indigenous females (54%). 
Assessment of acquired brain injury in Aboriginal and Torres Strait Islander Australians: guidance for DisabilityCare Australia
No full textIn early 2013, Brain Injury Australia was funded by the National Disability Insurance Scheme\u27s (NDIS) Practical Design Fund to develop a culturally appropriate NDIS assessment process for Aboriginal and Torres Strait Islander persons living with an acquired brain injury (ABI).This project was co-managed by Brain Injury Australia and Synapse (Brain Injury Association of Queensland, Inc.). The research was undertaken by researchers from James Cook University.The key results of this research were:guidelines for appropriate protocols for engaging Aboriginal and Torres Strait Islander Australians in the assessment process;a four-stage Planning and Assessment framework that describes the appropriate actions that DisabilityCare Australia Planners and/or Local Area Coordinators need to take during the assessment process when determining eligibility to DisabilityCare Australia; a prototype instrument toolkit (requiring scientific validation before use), containing cognitive and functional assessments that are culturally acceptable for assessment of acquired brain injury in Aboriginal and Torres Strait Islander Australians; and the identification of necessary training components for the professional development of DisabilityCare staff, including cultural awareness, competency and ABI training programmes and coursework.Authored by India Bohanna, Anne Stephens, Rachael Wargent, Juliette Catherall, Carolyn Timms, Deborah Graham and Alan Clough

Literature review of the interplay between education, employment, health and wellbeing for Aboriginal and Torres Strait Islander people in remote areas
No full textThe availability of timely, comprehensive and good quality data specifically relevant to remote Aboriginal and Torres Strait Islander notions of health and wellbeing has been a significant obstacle to understanding and addressing related disadvantage in a meaningful way. This literature review for the CRC-REP Interplay Between Health, Wellbeing, Education and Employment project explored existing wellbeing frameworks at global and local levels that are relevant to Aboriginal and Torres Strait Islander people in remote Australia.Current government frameworks that collect data about Aboriginal and Torres Strait Islander people often produce a narrative that describes deficit, disadvantage and dysfunction. The frameworks include the Aboriginal and Torres Strait Islander Health Performance Framework, the Overcoming Indigenous Disadvantage Framework, the Australia Bureau of Statistics Aboriginal and Torres Strait Islander Wellbeing Framework and the National Aboriginal and Torres Strait Islander Social Survey. These frameworks gather statistical information for the purposes of policy analysis and program development and therefore use indicators that are important to policy. Increasingly, government frameworks are including holistic measures of health such as cultural health, governance and the impacts of colonisation.This literature review has identified the need to develop a wellbeing framework that not only accurately represents education, employment, health and wellbeing and the interplay between these and other factors, but that also recognises the strengths and resilience of Aboriginal and Torres Strait people as well as reflecting their worldviews, perspectives and values. For example, a definition of ‘wellbeing’ that highlights the importance of physical, social, emotional, cultural and spiritual influences at the level of the individual and the community has been endorsed by Aboriginal and Torres Strait Islander groups and governments alike and sustained for over 20 years. Accordingly, this literature review has been organised along these topics.In addition, the literature suggests that optimal wellbeing occurs when there is strong cultural identity in combination with control, achievement and inclusion at a wider societal level, such as through successful engagement in education and employment. Listening to Aboriginal and Torres Strait Islander people to learn of their conceptual thinking, knowledge and understanding, and responding to their priorities and ideas are crucial parts of the policy equation to improve outcomes across education, employment, health and wellbeing. The challenges in developing an appropriate wellbeing framework, then, are ensuring the active involvement and participation of the Aboriginal and Torres Strait Islander people.One example of how this has worked is provided by the Community Indicators Victoria Project, which used local-level data to address issues that the local community identified as important. A focus on strengths is also important, and is exemplified in the Social and Emotional Wellbeing Framework of the National Aboriginal and Torres Strait Islander Health Council and National Mental Health Working Group. Various existing programs – such as ‘Caring for Country’ – can be adapted to capture data about connection to country, for example, and how that impacts on physical and mental health. Critically, the core domains of education, employment and health need to be extended to include activities and concepts that Aboriginal and Torres Strait Islander people consider important to these areas.Recommendations for the development of a wellbeing framework are proposed here, derived from information available in the literature. Rather than being definitive, these recommendations provide a starting point for consultation and adaption towards establishing a wellbeing framework and operational system for collecting and analysing long-term health and wellbeing data for Aboriginal and Torres Strait Islander people in remote Australia as part of the research conducted by CRC-REP
