Substance misuse in patients with schizophrenia : Epidemiology and management

Substance misuse in individuals with schizophrenia is very common, especially in young men, in communities where use is frequent and in people receiving inpatient treatment. Problematic use occurs at very low intake levels, so that most affected people are not physically dependent (with the exception of nicotine). People with schizophrenia and substance misuse have poorer symptomatic and functional outcomes than those with schizophrenia alone. Unless there is routine screening, substance misuse is often missed in assessments. Service systems tend to be separated, with poor inter-communication, and affected patients are often excluded from services because of their comorbidity. However, effective management of these disorders requires a fully integrated approach because of the close inter-relationship of the disorders. Use of atypical antipsychotics may be especially important in this population because of growing evidence (especially on clozapine and risperidone) that nicotine smoking, alcohol misuse and possibly some other substance misuse is reduced. Several pharmacotherapies for substance misuse can be used safely in people with schizophrenia, but the evidence base is small and guidelines for their use are necessarily derived from experience in the general population.

Pro-Am curators of Australian television history : how is their practice different from that of professional television historians?

Eleven Pro-Am curators of Australian television history were interviewed about their practice. The data helps us to understand the relationship between professional and Pro-Am approaches to Australian television history. There is no simple binary – the lines are blurred – but there are some differences. Pro-Am curators of Australian television history are not paid for their work and present other motivations for practice – particularly being that ‘weird child’ who was obsessed with gathering information and objects related to television. They have freedom to curate only programs and genres that interest them, and they tend to collect merchandise as much as program texts themselves. And they have less interest in formally cataloguing their material than do professional curators of Australian television history.

Estimating local stream fish assemblage attributes: Sampling effort and efficiency at two spatial scales

As part of a wider study to develop an ecosystem-health monitoring program for wadeable streams of south-eastern Queensland, Australia, comparisons were made regarding the accuracy, precision and relative efficiency of single-pass backpack electrofishing and multiple-pass electrofishing plus supplementary seine netting to quantify fish assemblage attributes at two spatial scales (within discrete mesohabitat units and within stream reaches consisting of multiple mesohabitat units). The results demonstrate that multiple-pass electrofishing plus seine netting provide more accurate and precise estimates of fish species richness, assemblage composition and species relative abundances in comparison to single-pass electrofishing alone, and that intensive sampling of three mesohabitat units (equivalent to a riffle-run-pool sequence) is a more efficient sampling strategy to estimate reach-scale assemblage attributes than less intensive sampling over larger spatial scales. This intensive sampling protocol was sufficiently sensitive that relatively small differences in assemblage attributes (<20%) could be detected with a high statistical power (1-β > 0.95) and that relatively few stream reaches (<4) need be sampled to accurately estimate assemblage attributes close to the true population means. The merits and potential drawbacks of the intensive sampling strategy are discussed, and it is deemed to be suitable for a range of monitoring and bioassessment objectives.

‘It's all scientific to me’ : focus group insights into why young people do not apply safe-sex knowledge

Despite rising levels of safe-sex knowledge in Australia, sexually transmitted infection notifications continue to increase. A culture-centred approach suggests it is useful in attempting to reach a target population first to understand their perspective on the issues. Twenty focus groups were conducted with 89 young people between the ages of 14 and 16 years. Key findings suggest that scientific information does not articulate closely with everyday practice, that young people get the message that sex is bad and they should not be preparing for it and that it is not appropriate to talk about sex. Understanding how young people think about these issues is particularly important because the focus groups also found that young people disengage from sources of information that do not match their own experiences.

Catering for cultural and linguistic diversity: Using teacher created information texts

Teachers in the Pacific region have often signalled the need for more locally produced information texts in both the vernacular and English, to engage their readers with local content and to support literacy development across the curriculum. The Information Text Awareness Project (ITAP), initially informed by the work of Nea Stewart-Dore, has provided a means to address this need through supporting local teachers to write their own information texts. The article reports on the impact of an ITAP workshop carried out in Nadi, Fiji in 2012. Nine teacher volunteers from the project trialled the use of the texts in their classrooms with positive results in relation to student learning and belief in themselves as writers.

The death of lifelong employment in Japan?

Lifelong employment in Japan is more trope than literal fact. As a synecdoche,it encapsulates Japan's system of industrial relations. As a metonym, it epitomises the employee-oriented communitarian firm (Abe and Shimizutani,2007, p. 347). As a metaphor, it represents Japan's distinctive form of stakeholder capitalism (Dore, 1993). Yet none of these tropes holds as a truth. Lifelong employment does not signify the dominant form of employment in Japan. It does not privilege employees' interests over business concerns. And it does not constitute a benign, kinder form of capitalism compared with the market-based model.

Pressure and alloying effects on the metal to insulator transition in NiS2-xSex studied by infrared spectroscopy

The metal to insulator transition in the charge-transfer NiS2-xSex compound has been investigated through infrared reflectivity. Measurements performed by applying pressure to pure NiS2 (lattice contraction) and by Se alloying (lattice expansion) reveal that in both cases an anomalous metallic state is obtained. We find that optical results are not compatible with the linear Se-alloying vs pressure-scaling relation previously established through transport, thus pointing out the substantially different microscopic origin of the two transitions.

Combined Raman and infrared investigation of the insulator-to-metal transition in NiS(2-x)Se(x) compounds

Ambient-condition Raman spectra were collected in the strongly correlated NiS(1-x)Se(x) pyrite (0 <= x <= 1.2). Two samples (x = 0 and x = 0.55) were studied as a function of pressure up to 10 GPa, and for the x = 0.55 sample the pressure dependence of the infrared reflectivity was also measured (0-10 GPa). This gave a complete picture of the optical response of that system on approaching the metallic state both by application of pressure and/or by Se alloying, which corresponds to a volume expansion. A peculiar nonmonotonic (V-shaped) volume dependence was found for the quasiparticle spectral weight of both pure and Se-doped compounds. In the x = 0.55 sample the vibrational frequencies of the chalcogen dimer show an anomalous volume dependence on entering the metallic phase. The abrupt softening observed, particularly significant for the Se-Se pair, indicates the relevant role of the softness of the Se-Se bond as previously suggested by theoretical calculations.

Application of Artificial Neural Networks and Particle Swarm Optimization for the Management of Groundwater Resources

Ground management problems are typically solved by the simulation-optimization approach where complex numerical models are used to simulate the groundwater flow and/or contamination transport. These numerical models take a lot of time to solve the management problems and hence become computationally expensive. In this study, Artificial Neural Network (ANN) and Particle Swarm Optimization (PSO) models were developed and coupled for the management of groundwater of Dore river basin in France. The Analytic Element Method (AEM) based flow model was developed and used to generate the dataset for the training and testing of the ANN model. This developed ANN-PSO model was applied to minimize the pumping cost of the wells, including cost of the pipe line. The discharge and location of the pumping wells were taken as the decision variable and the ANN-PSO model was applied to find out the optimal location of the wells. The results of the ANN-PSO model are found similar to the results obtained by AEM-PSO model. The results show that the ANN model can reduce the computational burden significantly as it is able to analyze different scenarios, and the ANN-PSO model is capable of identifying the optimal location of wells efficiently.

A Câmara Municipal do Rio de Janeiro, das invasões corsárias ao governo de Luis Vahia Monteiro (1710 a 1732): uma história de conflitos pelo uso do território colonial.

As câmaras municipais constituíram-se em um dos mais notáveis mecanismos de manutenção do vasto império ultramarino português. Originavam-se dos antigos conselhos medievais, aglutinavam os interesses das elites coloniais ao serem compostas pelos homens bons da colônia, detinham considerável poder sobre a sociedade local além de terem a liberdade de representar ao rei de Portugal seus anseios ou dificuldades. Paralelo, ao poder do senado da câmara municipal, encontravam-se as autoridades nomeadas pelo rei de Portugal: governadores coloniais. Este compartilhamento do poder na colônia gerava, muitas vezes, conflitos entre a câmara municipal e os funcionários régios. No Rio de Janeiro, setecentista, vários fatores internos e externos à colônia deterioraram as relações entre os governadores coloniais e os membros do senado.Tal situação agrava-se com as incursões corsárias francesas de 1710 e 1711 que demonstraram a fragilidade do império português que há muito deixara de ter um poder naval significativo, perdendo espaços para potências como a França, Inglaterra e Holanda. Incapaz de conter os inimigos no vasto oceano, desprovido de meios navais capazes de patrulhar os litorais de suas colônias na África, Ásia e América, em especial o do Brasil, o império português dependia cada vez mais dos recursos humanos de suas colônias para a manutenção do seu território ultramarino. A corte portuguesa sofreu duro impacto com a conquista da cidade do Rio de Janeiro por Duguay-Trouin e, ao longo dos próximos anos, procurou fortalecer o sistema defensivo de sua colônia com o envio de tropas e navios além da construção de novas fortalezas e o reaparelhamento do sistema defensivo já existente.Todo este esforço para a guerra era bancado, em sua maior parte, com recursos da própria colônia do Rio de Janeiro. Obviamente este ônus não agradava a incipiente elite mercantil que florescia na colônia resultando no fato de que a política de enclausurar o Rio de Janeiro entre muralhas e fortificações, ás custas da economia colonial, colocou em campos opostos os funcionários do rei e os membros do senado por várias vezes nas primeiras décadas do século XVIII. Surgiram inevitáveis conflitos pelo uso e posse do território urbano do Rio de Janeiro cada vez mais pontilhado por fortalezas, sulcado por extensas valas e trincheiras a impedir-lhe o crescimento urbano. Além do conflito territorial, em função da expansão da atividade mercantil desenvolvida pelos colonos, as disputas comerciais envolveram as elites locais, ávidas por lucros e impulsionadas ao comércio devido à descoberta do ouro na região das Minas, e as autoridades e comerciantes lusos, uns querendo controlar a atividade comercial que crescia em acelerado ritmo, outros querendo lucrar e disputar espaços com as elites coloniais locais. No meio destes embates encontrava-se a Câmara Municipal do Rio de Janeiro, objetivo maior desta pesquisa, a defender os interesses das elites da colônia, pois delas era representante. Era uma disputa em que, muitas vezes, seus membros pagaram com a perda da liberdade e dos seus bens frente a governadores coloniais mais intolerantes

Criação e trajetória de uma Agência no âmbito do Estado integral : o caso do SEBRAE

Este trabalho procura investigar o processo que deu origem ao Serviço Brasileiro de Apoio às Micro e Pequenas Empresas (SEBRAE), assim como a sua trajetória desde a criação até os dias atuais. O SEBRAE foi constituído, em 1972, no âmbito do Ministério de Planejamento e Coordenação Geral (MPCG) do governo Garrastazu Médici (1969-1974). A partir do fim dos anos 70, quando a crise do capital começou a produzir efeitos no país, a agência iniciou um processo paulatino de transformação, culminando na sua privatização, ocorrida no primeiro ano do governo Collor de Mello (1990-1992). Este processo consolidou a sua passagem definitiva da sociedade política para a sociedade civil e alterou, em grande medida, a função da agência junto ao bloco no poder. Ainda que algumas operações não tenham sofrido mudanças significativas, os seus agentes incorporaram definitivamente o papel de formuladores e de disseminadores de ideologia em apoio à consolidação de uma nova fase do capital. Neste sentido, o SEBRAE cumpre, nos dias atuais, o papel de produzir consenso na sociedade em torno da importância econômica e social das micro e pequenas empresas, auxilia a formulação de políticas públicas e leis voltadas para esta questão e, por fim, assume a função ética do Estado, através da qual realiza a tarefa educativa dos indivíduos visando ao "universal". A história da agência é analisada à luz das reflexões de Gramsci sobre hegemonia e Estado integral, capazes de, entre outros aspectos, auxiliar a compreensão das relações mediatas estabelecidas entre agências da sociedade civil e o bloco no poder

Indication of electron neutrino appearance from an accelerator-produced off-axis muon neutrino beam.

The T2K experiment observes indications of ν(μ) → ν(e) appearance in data accumulated with 1.43×10(20) protons on target. Six events pass all selection criteria at the far detector. In a three-flavor neutrino oscillation scenario with |Δm(23)(2)| = 2.4×10(-3)  eV(2), sin(2)2θ(23) = 1 and sin(2)2θ(13) = 0, the expected number of such events is 1.5±0.3(syst). Under this hypothesis, the probability to observe six or more candidate events is 7×10(-3), equivalent to 2.5σ significance. At 90% C.L., the data are consistent with 0.03(0.04) < sin(2)2θ(13) < 0.28(0.34) for δ(CP) = 0 and a normal (inverted) hierarchy.
