Early-Mid Holocene climatic variations in Tasmania, Australia: multi-proxy records in a stalagmite from Lynds Cave

Mass spectrometric uranium-series dating and C-O isotopic analysis of a stalagmite from Lynds Cave, northern Tasmania, Australia provide a high-resolution record of regional climate change between 5100 and 9200 yr before present (BP). Combined delta(18)O, delta(13)C, growth rate, initial U-234/U-238 and physical property (color, transparency and porosity) records allow recognition of seven climatic stages: Stage I ( > 9080 yr BP) - a relatively dry period at the beginning of stalagmite growth evidenced by elevated U-234/U-238; Stage II (9080-8600 yr BP) - a period of unstable climate characterized by high-frequency variability in temperature and bio-productivity; Stage 111 (8600-8000 yr BP) - a period of stable and moderate precipitation and stable and high bio-productivity, with a continuously rising temperature; Stage IV (8000-7400 yr BP) - the warmest period with high evaporation and low effective precipitation (rainfall less evaporation); Stage V (7400-7000 yr BP) - the wettest period with highest stalagmite growth and enhanced but unstable bio-productivity; Stage VI (7000-6600 yr BP) - a period with a significantly reduced precipitation and bio-productivity without noticeable change in temperature; Stage VII (6600-5100 yr BP) - a period of lowest temperature and precipitation marking a significant climatic deterioration. Overall, the records suggest that the warmest climate occurred between 8000 and 7400 yr BP, followed by a wettest period between 7400 and 7000 yr BP. These are broadly correlated with the so-called 'Mid Holocene optimum' previously proposed using pollen and lake level records. However, the timing and resolution of the speleothem. record from Lynds Cave are significantly higher than in both the pollen and lake level records. This allows us to correlate the abrupt change in physical property, delta(18)O, delta(13)C, growth rate, and initial U-234/U-238 of the stalagmite at similar to8000 yr BP with a global climatic event at Early-Mid Holocene transition.

Health services research using linked records: who consents and what is the gain?

Objective: To assess consent to record linkage, describe the characteristics of consenters and compare self-report versus Medicare records of general practitioner use. Method. Almost 40,000 women in the Australian Longitudinal Study on Women's Health were sent a request by mail for permission to link their Medicare records and survey data. Results: 19,700 women consented: 37% of young (18-23 years), 59% of mid-age (4550 years) and 53% of older women (70-75 years). Consenters tended to have higher levels of education and, among the older cohort, were in better health than nonconsenters. Women tended to under-report the number of visits to general practitioners. Conclusions: Record linkage of survey and Medicare data on a large scale is feasible. The linked data provide information on health and socio-economic status which are valuable for understanding health service utilisation. Implications: Linked records provide a powerful tool for health care research, particularly in longitudinal studies.

Relationship of high energy expenditure and variation in dietary intake with reporting accuracy on 7 day food records and diet histories in a group of healthy adult volunteers

Objectives: To assess the accuracy of reporting from both a diet history and food record and identify some of the characteristics of more accurate reporters in a group of healthy adult volunteers for an energy balance study. Design: Prospective measurements in free-living people. Setting: Wollongong, Australia. Subjects: Fifteen healthy volunteers (seven male, eight female; aged 22 -59 y; body mass index (BMI) 19 - 33 kg/m(2)) from the local community in the city of Wollongong, Australia. Interventions: Measurement of energy intake via diet history interview and 7 day food records, total energy expenditure by the doubly labelled water technique over 14 days, physical activity by questionnaire, and body fat by dual-energy X-ray absorptiometry. Results: Increased misreporting of energy intake was associated with increased energy expenditure (r = 0.90, P < 0.0001, diet history; r(s)=0.79, P=0.0005, food records) but was not associated with age, sex, BMI or body fat. Range in number of recorded dinner foods correlated positively with energy expenditure (r(s)=0.63, P=0.01) and degree of misreporting (r(s)=0.71, P=0.003, diet history; r(s)=0.63, P=0.01, food records). Variation in energy intake at dinner and over the whole day identified by the food records correlated positively with energy expenditure (r=0.58, P = 0.02) and misreporting on the diet history (r=0.62, P=0.01). Conclusions: Subjects who are highly active or who have variable dietary and exercise behaviour may be less accurate in reporting dietary intake. Our findings indicate that it may be necessary to screen for these characteristics in studies where accuracy of reporting at an individual level is critical. Sponsorship: The study was supported in part by Australian Research Council funds made available through the University of Wollongong.

Accounting and the “Doctor-Manager Relationship”

The adoption of the “new public management” in the hospital sector brought about greater presence and power to professional managers in hospitals, thus increasing the risk of conflict in the doctor-manager relationship. Aiming to enrich the discussion on the factors that could be the bases for this conflict and considering the role of accounting, the study presented here corresponds, basically, to what we call “content analysis” of qualitative studies. The results demonstrate that the Portuguese doctors as the sample studied accept, in essence, the principles of enterprise management and recognize the use of accounting information in the scope of their functions as long as they are called to participate as legitimate actors, and authorities respect their desires to preserve a practice which they consider of quality.

A sea urchin (Diadema africanum Rodriguez et al., 2013) and a pipe fish (Syngnathus phlegon Risso, 1827) : two new records for the Azores

Maciel & Costa (2010) reported the presence of 17 species of costal sea urchins (Echinoidea) in the Azores, while Porteiro et al. (2010) reported six species of pipefishes (Syngnathidae) for the area. During SCUBA diving at Santa Maria Island, the first author detected a sea urchin and a pipe fish which are new to the marine fauna of the Azores.

Records of predatory, con-specific and human induced mauls on fish from the Northeast Atlantic and Black Sea

Present study aims to describe records of mauled and con-specific injures in various fish inhabiting different environment and to discuss possible impacts on fish behavior and ontogenesis. The fish specimens were collected from the Black Sea and Azores Islands (NE Atlantic). Individuals of European flounder, Pleuronectes flesus, common stingray, Dasyatis pastinaca and turbot, Scophthalmus maximus with missing dorsal and caudal fins and flesh, were found in the Black Sea. Specimens with severe mauls of the ocean sunfish, Mola mola, almaco jack, Seriola rivoliana and sargo, Diplodus sargus were recorded from the Azores Islands. All of them were caught alive and survived severe mauls caused by predators or by accidents with propellers, fishing nets. The NE Atlantic records, although possibly caused by natural predation, are more probably than not the result of negative interactions with human activity. Numerous records of mauled fish species from both regions show that the problem with adverse effects of fisheries is quite important. Predatory and con-specific injuries obviously are compatible with basic fish vital functions of described cases. The problem with negative anthropogenic interactions seems to be insufficiently investigated and need more attention by responsible managers and decision makers.

New records of Histoplasma capsulatum from wild animals in the Brazilian Amazon

Twenty-eight isolates of Histoplasma capsulation were obtained from eight species of forest mammals from the States of Amazonas, Pará and Rondônia in the Amazon Region of Brazil. Primary isolates were obtained by inoculating triturated liver and spleen tissue intradermally and intraperito-neally in hamsters. Mycological diagnosis in hamsters presenting lesions was confirmed by histopathology and culture on Sabouraud dextrose-agar. Infected hamsters developed signs of disease within two to nine months; all had disseminated visceral lesions and most also had skin lesions at the sites of inoculation. None of the hamsters inoculated with skin macerates of the original hosts developed histoplasmosis, and histopathological examination of the viscera of the wild hosts failed to reveal H. capsulation. Prevalence of infection was considerably higher in females than in males both for the opossum Didelphis marsupialis and for total wild animals (479) examined. It is proposed that canopy-dwelling mammals may acquire the infection from conidia borne on convective currents in hollow trees with openings at ground-level.

Reformulação de um Sistema de Gestão de Consumos de Energia

Atualmente a energia é considerada um vetor estratégico nas diversas organizações. Assim sendo, a gestão e a utilização racional da energia são consideradas instrumentos fundamentais para a redução dos consumos associados aos processos de produção do sector industrial. As ações de gestão energética não deverão ficar pela fase do projeto das instalações e dos meios de produção, mas sim acompanhar a atividade da Empresa. A gestão da energia deve ser sustentada com base na realização regular de diagnósticos energéticos às instalações consumidoras e concretizada através de planos de atuação e de investimento que apresentem como principal objetivo a promoção da eficiência energética, conduzindo assim à redução dos respetivos consumos e, consequentemente, à redução da fatura energética. Neste contexto, a utilização de ferramentas de apoio à gestão de energia promovem um consumo energético mais racional, ou seja, promovem a eficiência energética e é neste sentido que se insere este trabalho. O presente trabalho foi desenvolvido na Empresa RAR Açúcar e apresentou como principais objetivos: a reformulação do Sistema de Gestão de Consumos de Energia da Empresa, a criação de um modelo quantitativo que permitisse ao Gestor de Energia prever os consumos anuais de água, fuelóleo e eletricidade da Refinaria e a elaboração de um plano de consumos para o ano de 2014 a partir do modelo criado. A reformulação do respetivo Sistema de Gestão de Consumos resultou de um conjunto de etapas. Numa primeira fase foi necessário efetuar uma caraterização e uma análise do atual Sistema de Gestão de Consumos da Empresa, sistema composto por um conjunto de sete ficheiros de cálculo do programa Microsoft Excel©. Terminada a análise, selecionada a informação pertinente e propostas todas as melhorias a introduzir nos ficheiros, procedeu-se à reformulação do respetivo SGE, reduzindo-se o conjunto de ficheiros de cálculo para apenas dois ficheiros, um onde serão efetuados e visualizados todos os registos e outro onde serão realizados os cálculos necessários para o controlo energético da Empresa. O novo Sistema de Gestão de Consumos de Energia será implementado no início do ano de 2015. Relativamente às alterações propostas para as folhas de registos manuais, estas já foram implementadas pela Empresa. Esta aplicação prática mostrou-se bastante eficiente uma vez que permitiu grandes melhorias processuais nomeadamente, menores tempos de preenchimento das mesmas e um encurtamento das rotas efetuadas diariamente pelos operadores. Através do levantamento efetuado aos diversos contadores foi possível identificar todas as áreas onde será necessário a sua instalação e a substituição de todos os contadores avariados, permitindo deste modo uma contabilização mais precisa de todos os consumos da Empresa. Com esta reestruturação o Sistema de Gestão de Consumos tornou-se mais dinâmico, mais claro e, principalmente, mais eficiente. Para a criação do modelo de previsão de consumos da Empresa foi necessário efetuar-se um levantamento dos consumos históricos de água, eletricidade, fuelóleo e produção de açúcar de dois anos. Após este levantamento determinaram-se os consumos específicos de água, fuelóleo e eletricidade diários (para cada semana dos dois anos) e procedeu-se à caracterização destes consumos por tipo de dia. Efetuada a caracterização definiu-se para cada tipo de dia um consumo específico médio com base nos dois anos. O modelo de previsão de consumos foi criado com base nos consumos específicos médios dos dois anos correspondentes a cada tipo de dia. Procedeu-se por fim à verificação do modelo, comparando-se os consumos obtidos através do modelo (consumos previstos) com os consumos reais de cada ano. Para o ano de 2012 o modelo apresenta um desvio de 6% na previsão da água, 12% na previsão da eletricidade e de 6% na previsão do fuelóleo. Em relação ao ano de 2013, o modelo apresenta um erro de 1% para a previsão dos consumos de água, 8% para o fuelóleo e de 1% para a eletricidade. Este modelo permitirá efetuar contratos de aquisição de energia elétrica com maior rigor o que conduzirá a vantagens na sua negociação e consequentemente numa redução dos custos resultantes da aquisição da mesma. Permitirá também uma adequação dos fluxos de tesouraria à necessidade reais da Empresa, resultante de um modelo de previsão mais rigoroso e que se traduz numa mais-valia financeira para a mesma. Foi também proposto a elaboração de um plano de consumos para o ano de 2014 a partir do modelo criado em função da produção prevista para esse mesmo ano. O modelo apresenta um desvio de 24% na previsão da água, 0% na previsão da eletricidade e de 28% na previsão do fuelóleo.

It was found A. fulica with Metastrongylidae larvae without known medical and veterinary importance in the cities of Carapicuíba, Embu-Guaçu, Itapevi, São Caetano do Sul, São Paulo and Taboão da Serra.

TWO NEW RECORDS OF Isomyia paurogonita FANG AND FAN, 1986 AND Sumatria latifrons Malloch, 1926 (DIPTERA: CALLIPHORIDAE) FROM NORTHERN THAILAND, WITH REVISED KEY TO THE SPECIES OF Isomyia

During the annual fly survey at Doi Nang Kaew in Doi Saket District, Chiang Mai Province of Thailand in 2011, Isomyia paurogonitaFang & Fan, 1986 (Diptera: Calliphoridae) and Sumatria latifrons Malloch, 1926 (Diptera: Calliphoridae) were collected for the first time in Thailand. They are the rare species of the subfamily Rhiniinae (tribe Cosminini). Prior to this finding, fifteen species of Isomyia and two species of Sumatriawere recorded from Thailand. Therefore, 96 blow fly species have been found in this country. These new locality records of both flies are very important for further research on their biology and ecology in Thailand.
