Priority list of endemic diseases for the red meat industries

This report provides a systematic review of the most economically damaging endemic diseases and conditions for the Australian red meat industry (cattle, sheep and goats). A number of diseases for cattle, sheep and goats have been identified and were prioritised according to their prevalence, distribution, risk factors and mitigation. The economic cost of each disease as a result of production losses, preventive costs and treatment costs is estimated at the herd and flock level, then extrapolated to a national basis using herd/flock demographics from the 2010-11 Agricultural Census by the Australian Bureau of Statistics. Information shortfalls and recommendations for further research are also specified. A total of 17 cattle, 23 sheep and nine goat diseases were prioritised based on feedback received from producer, government and industry surveys, followed by discussions between the consultants and MLA. Assumptions of disease distribution, in-herd/flock prevalence, impacts on mortality/production and costs for prevention and treatment were obtained from the literature where available. Where these data were not available, the consultants used their own expertise to estimate the relevant measures for each disease. Levels of confidence in the assumptions for each disease were estimated, and gaps in knowledge identified. The assumptions were analysed using a specialised Excel model that estimated the per animal, herd/flock and national costs of each important disease. The report was peer reviewed and workshopped by the consultants and experts selected by MLA before being finalised. Consequently, this report is an important resource that will guide and prioritise future research, development and extension activities by a variety of stakeholders in the red meat industry. This report completes Phase I and Phase II of an overall four-Phase project initiative by MLA, with identified data gaps in this report potentially being addressed within the later phases. Modelling the economic costs using a consistent approach for each disease ensures that the derived estimates are transparent and can be refined if improved data on prevalence becomes available. This means that the report will be an enduring resource for developing policies and strategies for the management of endemic diseases within the Australian red meat industry.

Vallankumous kotona! : Arkielämän visuaalinen murros 1960-luvun lopussa ja 1970-luvun alussa

Revolution at home! Visual Changes in Everyday Life in Finland in the Late 1960s and Early 1970s The purpose of my research was to investigate the visual changes in private homes in Finland during the 1960s and 1970s. The 1960s is often described as a turning point in Finnish life, a time when the society's previous agricultural orientation began to give way first to an industrial orientation and then, by the end of the 1970s, to a service orientation. My title refers to three elements in the transition period: the question of daily life; the timeframe; and the visual changes observable in private homes, which in retrospect signalled a kind of revolution in the social orientation. Those changes appeared not only in colours and designs but also in the forms and materials of household objects. My premise is that analysing interiors from a historical perspective can reveal valuable information about Finnish society and social attitudes, information that might easily escape attention otherwise. I have used the time-honoured method of collecting narratives. As far back as Aristotle, formulating narratives has been a means of gaining knowledge. By collecting and classifying narratives about the 1960s and 1970s, it is possible to gain new insight into these important decades. The archetypal 1960s narrative, involving student demonstrations and young people's efforts to improve society, is well known. Less well known is the narrative that relates the changes going on in daily life. Substantially the study focuses mainly on fabrics, porcelain ware and the use of plastics. Marimekko's style is especially important when following innovations in the 1950s, 1960s and 1970s. Porcelain production at the Arabia factory was another element that had a great influence on the look of Finnish homes and kitchens; and a further widespread phenomenon of the late 1960s and early 1970s was the use of plastics in many different forms. Further evidence was sought in Anttila department store mail catalogues, which displayed products that were marketed on a large scale, as well as in magazines such as Avotakka. The terminal point of the visual evolution is the real homes, as seen in the questionnaire "Homemade". I have used the 800 pages of the oral history text that respondents of the Finnish Literature Society have written about their first home in the 1960s. I also used archival material on actual homes in Helsinki from the archives of the Helsinki City Museum. The basic story is the elite narrative, which was produced by students in the 1960s. My main narrative from the same time is visual change in everyday life in the late 1960s and early 1970s. I have classified the main narrative of visual change into four subcategories: the narrative of national ideas, the narrative of a better standard of living, the narrative of objects in the culture of everyday life and the narrative of changing colour and form.

Directional dominance on stature and cognition in diverse human populations

Homozygosity has long been associated with rare, often devastating, Mendelian disorders1, and Darwin was one of the first to recognize that inbreeding reduces evolutionary fitness2. However, the effect of the more distant parental relatedness that is common in modern human populations is less well understood. Genomic data now allow us to investigate the effects of homozygosity on traits of public health importance by observing contiguous homozygous segments (runs of homozygosity), which are inferred to be homozygous along their complete length. Given the low levels of genome-wide homozygosity prevalent in most human populations, information is required on very large numbers of people to provide sufficient power3, 4. Here we use runs of homozygosity to study 16 health-related quantitative traits in 354,224 individuals from 102 cohorts, and find statistically significant associations between summed runs of homozygosity and four complex traits: height, forced expiratory lung volume in one second, general cognitive ability and educational attainment (P < 1 × 10−300, 2.1 × 10−6, 2.5 × 10−10 and 1.8 × 10−10, respectively). In each case, increased homozygosity was associated with decreased trait value, equivalent to the offspring of first cousins being 1.2 cm shorter and having 10 months’ less education. Similar effect sizes were found across four continental groups and populations with different degrees of genome-wide homozygosity, providing evidence that homozygosity, rather than confounding, directly contributes to phenotypic variance. Contrary to earlier reports in substantially smaller samples5, 6, no evidence was seen of an influence of genome-wide homozygosity on blood pressure and low density lipoprotein cholesterol, or ten other cardio-metabolic traits. Since directional dominance is predicted for traits under directional evolutionary selection7, this study provides evidence that increased stature and cognitive function have been positively selected in human evolution, whereas many important risk factors for late-onset complex diseases may not have been.

Asymmetric cross-coupled differential pair configuration to realize neuron activation function and its derivative

In this brief, we present a new circuit technique to generate the sigmoid neuron activation function (NAF) and its derivative (DNAF). The circuit makes use of transistor asymmetry in cross-coupled differential pair to obtain the derivative. The asymmetry is introduced through external control signal, as and when required. This results in the efficient utilization of the hard-ware by realizing NAF and DNAF using the same building blocks. The operation of the circuit is presented in the subthreshold region for ultra low-power applications. The proposed circuit has been experimentally prototyped and characterized as a proof of concept on the 1.5-mum AMI technology.

Collecting data from distributed FOSS projects

A key trait of Free and Open Source Software (FOSS) development is its distributed nature. Nevertheless, two project-level operations, the fork and the merge of program code, are among the least well understood events in the lifespan of a FOSS project. Some projects have explicitly adopted these operations as the primary means of concurrent development. In this study, we examine the effect of highly distributed software development, is found in the Linux kernel project, on collection and modelling of software development data. We find that distributed development calls for sophisticated temporal modelling techniques where several versions of the source code tree can exist at once. Attention must be turned towards the methods of quality assurance and peer review that projects employ to manage these parallel source trees. Our analysis indicates that two new metrics, fork rate and merge rate, could be useful for determining the role of distributed version control systems in FOSS projects. The study presents a preliminary data set consisting of version control and mailing list data.

Perspektiv på språkprocessering

Automatisk språkprocessering har efter mer än ett halvt sekel av forskning blivit ett mycket viktigt område inom datavetenskapen. Flera vetenskapligt viktiga problem har lösts och praktiska applikationer har nått programvarumarknaden. Disambiguering av ord innebär att hitta rätt betydelse för ett mångtydigt ord. Sammanhanget, de omkringliggande orden och kunskap om ämnesområdet är faktorer som kan användas för att disambiguera ett ord. Automatisk sammanfattning innebär att förkorta en text utan att den relevanta informationen går förlorad. Relevanta meningar kan plockas ur texten, eller så kan en ny, kortare text genereras på basen av fakta i den ursprungliga texten. Avhandlingen ger en allmän översikt och kort historik av språkprocesseringen och jämför några metoder för disambiguering av ord och automatisk sammanfattning. Problemområdenas likheter och skillnader lyfts fram och metodernas ställning inom datavetenskapen belyses.

Studies on Stone Age Housepits in Fennoscandia (4000 - 2000 cal BC) : Changes in ground plan, site location and degree of sedentism

Housepits have a remarkably short research history as compared to Fennoscandian archaeological research on the Stone Age in general. The current understanding of the numbers and the distribution of Stone Age housepits in the Nordic countries has, for the most part, been shaped by archaeological studies carried out over the last twenty to thirty years. The main subjects of this research are Neolithic housepits, which are archaeological remains of semi-subterranean pithouses. This dissertation consists of five peer-reviewed articles and a synthesis paper. The articles deal with the development of housepits as seen in the data gathered from Finland (the Lake Saimaa area and south-eastern Finland) and Russia (the Karelian Isthmus). This synthesis expands the discussion of the changes observed in the Papers to include Fennoscandian housepit research as a whole. Certain changes in the size, shape, environmental location, and clustering of housepits extended into various cultures and ecological zones in northern Fennoscandia. Previously, the evolution of housepits has been interpreted to have been caused by the adaptation of Neolithic societies to prevailing environmental circumstances or to re-organization following contacts with the agrarian Corded Ware/Battle Axe Cultures spreading to North. This dissertation argues for two waves of change in the pithouse building tradition. Both waves brought with them certain changes in the pithouses themselves and in the practices of locating the dwellings in the environment/landscape. The changes in housepits do not go hand in hand with other changes in material culture, nor are the changes restricted to certain ecological environments. Based on current information, it appears that the changes relate primarily to the spread of new concepts of housing and possibly to new technology, as opposed to representing merely a local response to environmental factors. This development commenced already before the birth of the Corded Ware/Battle Axe Cultures. Therefore, the changes are argued to have resulted from the spreading of new ideas through the same networks that actively distributed commodities, exotic goods, and raw materials over vast areas between the southern Baltic Sea, the north-west Russian forest zone, and Fennoscandia.

A via L-arginina-óxido nítrico no transtorno depressivo e sua associação com a função plaquetária e o estresse oxidativo

O transtorno depressivo (TD) é um fator de risco cardiovascular independente que apresenta elevada morbi-mortalidade. Recentes evidências sugerem a participação do óxido nítrico (NO), potente vasodilatador e anti-agregante plaquetário, na patogênese de doenças cardiovasculares e psiquiátricas. A síntese do NO ocorre através da conversão do aminoácido L-arginina em L-citrulina e NO, pela ação da enzima NO sintase (NOS). Esta tese aborda o papel da via L-arginina-NO em plaquetas de pacientes com TD e sua associação com a função plaquetária e estresse oxidativo. Para análise comportamental da depressão em modelo animal, foi utilizado o modelo de estresse pós-natal de separação única (SMU). Os animais foram divididos em quatro grupos para a realização do estudo: Grupo Controle Sedentário (GCS), Grupo Controle Exercício (GCE), Grupo SMU Sedentário (SMUS) e Grupo SMU Exercício (SMUE). O treinamento físico (TF) dos animais englobou 8 semanas, com duração de 30 minutos e uma velocidade de treinamento estabelecida pelo teste máximo (TE). Para o estudo em humanos, 10 pacientes com TD com score Hamilton: 201, (média de idade: 384anos), foram pareados com 10 indivíduos saudáveis (média de idade: 383anos). Os estudos em humanos e animais foram aprovados pelos Comitês de Ética: 1436 - CEP/HUPE e CEUA/047/2010, respectivamente. Foi mensurado em humanos e em animais: transporte de L-arginina, concentração GMPc, atividade das enzimas NOS e superóxido dismutase (SOD) em plaquetas e cortisol sistêmico. Experimentos realizados somente em humanos: expressão das enzimas NOS, arginase e guanilato ciclase através de Western Blotting. A agregação plaquetária foi induzida por colágeno e foi realizada análise sistêmica de proteína C-reativa, fibrinogênio e L-arginina. Para o tratamento estatístico utilizou-se três testes estatísticos para avaliar as diferenças das curvas de sobrevida: Kaplan-Meier, e os testes de Tarone-Ware e Peto-Prentice. Em humanos, houve uma redução do transporte de L-arginina, da atividade das enzimas NOS e SOD, e da concentração de GMPc em plaquetas, e nas concentrações plasmáticas de L-arginina no grupo com TD em relação ao grupo controle. Foi observado um aumento dos níveis plasmáticos de fibrinogênio no TD. Esses resultados demonstram uma inibição da via L-arginina-NO-GMPc e da enzima anti-oxidante SOD em pacientes com TD sem afetar a função plaquetária. Em relação ao TF, para o modelo animal, foram encontradas alterações iniciais quanto à distância percorrida e tempo de execução do TE entre os grupos controles e o grupos SMUs, apresentando estes últimos menores valores para o TE. Após 8 semanas de TF, verificou-se um maior influxo no transporte de L-arginina para o SMUE em comparação ao grupo SMUS. As diferenças observadas para o tempo e a distância percorrida no TE inicial entre os grupos controle e no modelo de estresse foram revertidas após as 8 semanas de TF, demonstrando o efeito benéfico do exercício físico na capacidade cardiorespiratória em modelos de depressão.
