Diferentes arranjos institucionais resultam em diferentes incentivos para a realização de trocas econômicas. Com efeito, estruturas regulatórias implementadas em determinado contexto histórico-econômico podem resultar em consequências diversas daquelas originariamente pretendidas, impondo ao regulador a necessidade de constante monitoramento e de intervenções com vistas a diagnosticar e corrigir ou minimizar possíveis distorções nas relações entre os atores envolvidos. Assim, esta dissertação tem por objetivo analisar o funcionamento do Consórcio do Seguro DPVAT como mecanismo de conexão entre seus diversos stakeholders. Pretende-se analisar a existência de conflitos de interesses derivados das diversas relações entre as partes interligadas – geradas pelo arranjo institucional firmado para a gestão dos recursos arrecadados com os prêmios pagos pelos proprietários de veículo automotor para o Seguro de Danos Pessoais Causados por Veículos Automotores de Via Terrestre, ou por sua carga, a Pessoas Transportadas ou Não (DPVAT) – que possam suscitar intervenção regulatória no sentido de evitá-los, ou, ao menos, mitigá-los. A pesquisa é conduzida a partir da identificação dos comportamentos esperados de agentes econômicos autointeressados, tendo por referência os pressupostos da Nova Economia Institucional sob a perspectiva da Teoria da Agência, e do exame das principais mudanças legislativas havidas na estrutura do seguro obrigatório de trânsito no Brasil nos últimos 50 anos. Na sequência, com base em elementos teóricos e empíricos, foram identificados e analisados três conflitos de agência entre os stakeholders do Consórcio DPVAT: o primeiro seria aquele havido entre a entidade gestora do Consórcio DPVAT (agente) e as sociedades seguradoras consorciadas (principal); o segundo conflito observado refere-se à relação mantida entre a entidade gestora do Consórcio DPVAT (agente) e o órgão regulador (principal); e, por fim, o conflito de agência existente entre a seguradora que administra o referido consórcio (agente) e os proprietários de veículo automotor (principal).

This special issue of Cultural Science Journal is devoted to the report of a groundbreaking experiment in re-coordinating global markets for specialist scholarly books and enabling the knowledge commons: the Knowledge Unlatched proof-of-concept pilot. The pilot took place between January 2012 and September 2014. It involved libraries, publishers, authors, readers and research funders in the process of developing and testing a global library consortium model for supporting Open Access books. The experiment established that authors, librarians, publishers and research funding agencies can work together in powerful new ways to enable open access; that doing so is cost effective; and that a global library consortium model has the potential dramatically to widen access to the knowledge and ideas contained in book-length scholarly works.

The Enhancing NeuroImaging Genetics through Meta-Analysis (ENIGMA) Consortium is a collaborative network of researchers working together on a range of large-scale studies that integrate data from 70 institutions worldwide. Organized into Working Groups that tackle questions in neuroscience, genetics, and medicine, ENIGMA studies have analyzed neuroimaging data from over 12,826 subjects. In addition, data from 12,171 individuals were provided by the CHARGE consortium for replication of findings, in a total of 24,997 subjects. By meta-analyzing results from many sites, ENIGMA has detected factors that affect the brain that no individual site could detect on its own, and that require larger numbers of subjects than any individual neuroimaging study has currently collected. ENIGMA's first project was a genome-wide association study identifying common variants in the genome associated with hippocampal volume or intracranial volume. Continuing work is exploring genetic associations with subcortical volumes (ENIGMA2) and white matter microstructure (ENIGMA-DTI). Working groups also focus on understanding how schizophrenia, bipolar illness, major depression and attention deficit/hyperactivity disorder (ADHD) affect the brain. We review the current progress of the ENIGMA Consortium, along with challenges and unexpected discoveries made on the way.

Quantitative ultrasound of the heel captures heel bone properties that independently predict fracture risk and, with bone mineral density (BMD) assessed by X-ray (DXA), may be convenient alternatives for evaluating osteoporosis and fracture risk. We performed a meta-analysis of genome-wide association (GWA) studies to assess the genetic determinants of heel broadband ultrasound attenuation (BUA; n 5 14 260), velocity of sound (VOS; n 5 15 514) and BMD (n 5 4566) in 13 discovery cohorts. Independent replication involved seven cohorts with GWA data (in silico n 5 11 452) and new genotyping in 15 cohorts (de novo n 5 24 902). In combined random effects, meta-analysis of the discovery and replication cohorts, nine single nucleotide polymorphisms (SNPs) had genome-wide significant (P < 5 3 108) associations with heel bone properties. Alongside SNPs within or near previously identified osteoporosis susceptibility genes including ESR1 (6q25.1: rs4869739, rs3020331, rs2982552), SPTBN1 (2p16.2: rs11898505), RSPO3 (6q22.33: rs7741021), WNT16 (7q31.31: rs2908007), DKK1 (10q21.1: rs7902708) and GPATCH1 (19q13.11: rs10416265), we identified a new locus on chromosome 11q14.2 (rs597319 close to TMEM135, a gene recently linked to osteoblastogenesis and longevity) significantly associated with both BUA and VOS (P < 8.23 3 1014). In meta-analyses involving 25 cohorts with up to 14 985 fracture cases, six of 10 SNPs associated with heel bone properties at P < 5 3 106 also had the expected direction of association with any fracture (P < 0.05), including threeSNPswithP < 0.005: 6q22.33 (rs7741021), 7q31.31 (rs2908007) and 10q21.1 (rs7902708). In conclusion, thisGWAstudy reveals the effect of several genescommon to central DXA-derivedBMDand heel ultrasound/DXAmeasures and points to anewgenetic locus with potential implications for better understanding of osteoporosis pathophysiology.

Background Genome-wide association studies have identified multiple genetic variants associated with prostate cancer risk which explain a substantial proportion of familial relative risk. These variants can be used to stratify individuals by their risk of prostate cancer. Methods We genotyped 25 prostate cancer susceptibility loci in 40,414 individuals and derived a polygenic risk score (PRS).We estimated empirical odds ratios (OR) for prostate cancer associated with different risk strata defined by PRS and derived agespecific absolute risks of developing prostate cancer by PRS stratum and family history. Results The prostate cancer risk for men in the top 1% of the PRS distribution was 30.6 (95% CI, 16.4-57.3) fold compared with men in the bottom 1%, and 4.2 (95% CI, 3.2-5.5) fold compared with the median risk. The absolute risk of prostate cancer by age of 85 years was 65.8% for a man with family history in the top 1% of the PRS distribution, compared with 3.7% for a man in the bottom 1%. The PRS was only weakly correlated with serum PSA level (correlation = 0.09). Conclusions Risk profiling can identify men at substantially increased or reduced risk of prostate cancer. The effect size, measured by OR per unit PRS, was higher in men at younger ages and in men with family history of prostate cancer. Incorporating additional newly identified loci into a PRS should improve the predictive value of risk profiles. Impact:We demonstrate that the risk profiling based on SNPs can identify men at substantially increased or reduced risk that could have useful implications for targeted prevention and screening programs.

Depending on their developmental stage in the life cycle, malaria parasites develop within or outside host cells, and in extremely diverse contexts such as the vertebrate liver and blood circulation, or the insect midgut and hemocoel. Cellular and molecular mechanisms enabling the parasite to sense and respond to the intra- and the extra-cellular environments are therefore key elements for the proliferation and transmission of Plasmodium, and therefore are, from a public health perspective, strategic targets in the fight against this deadly disease. The MALSIG consortium, which was initiated in February 2009, was designed with the primary objective to integrate research ongoing in Europe and India on i) the properties of Plasmodium signalling molecules, and ii) developmental processes occurring at various points of the parasite life cycle. On one hand, functional studies of individual genes and their products in Plasmodium falciparum (and in the technically more manageable rodent model Plasmodium berghei) are providing information on parasite protein kinases and phosphatases, and of the molecules governing cyclic nucleotide metabolism and calcium signalling. On the other hand, cellular and molecular studies are elucidating key steps of parasite development such as merozoite invasion and egress in blood and liver parasite stages, control of DNA replication in asexual and sexual development, membrane dynamics and trafficking, production of gametocytes in the vertebrate host and further parasite development in the mosquito. This article, which synthetically reviews such signalling molecules and cellular processes, aims to provide a glimpse of the global frame in which the activities of the MALSIG consortium will develop over the next three years.

Background Epidemiological studies suggest a potential role for obesity and determinants of adult stature in prostate cancer risk and mortality, but the relationships described in the literature are complex. To address uncertainty over the causal nature of previous observational findings, we investigated associations of height- and adiposity-related genetic variants with prostate cancer risk and mortality. Methods We conducted a case–control study based on 20,848 prostate cancers and 20,214 controls of European ancestry from 22 studies in the PRACTICAL consortium. We constructed genetic risk scores that summed each man’s number of height and BMI increasing alleles across multiple single nucleotide polymorphisms robustly associated with each phenotype from published genome-wide association studies. Results The genetic risk scores explained 6.31 and 1.46 % of the variability in height and BMI, respectively. There was only weak evidence that genetic variants previously associated with increased BMI were associated with a lower prostate cancer risk (odds ratio per standard deviation increase in BMI genetic score 0.98; 95 % CI 0.96, 1.00; p = 0.07). Genetic variants associated with increased height were not associated with prostate cancer incidence (OR 0.99; 95 % CI 0.97, 1.01; p = 0.23), but were associated with an increase (OR 1.13; 95 % CI 1.08, 1.20) in prostate cancer mortality among low-grade disease (p heterogeneity, low vs. high grade <0.001). Genetic variants associated with increased BMI were associated with an increase (OR 1.08; 95 % CI 1.03, 1.14) in all-cause mortality among men with low-grade disease (p heterogeneity = 0.03). Conclusions We found little evidence of a substantial effect of genetically elevated height or BMI on prostate cancer risk, suggesting that previously reported observational associations may reflect common environmental determinants of height or BMI and prostate cancer risk. Genetically elevated height and BMI were associated with increased mortality (prostate cancer-specific and all-cause, respectively) in men with low-grade disease, a potentially informative but novel finding that requires replication.

Specialist scholarly books, including monographs, allow researchers to present their work, pose questions and to test and extend areas of theory through long-form writing. In spite of the fact that research communities all over the world value monographs and depend heavily on them as a requirement of tenure and promotion in many disciplines, sales of this kind of book are in free fall, with some estimates suggesting declines of as much as 90% over twenty years (Willinsky 2006). Cashstrapped monograph publishers have found themselves caught in a negative cycle of increasing prices and falling sales, with few resources left to support experimentation, business model innovation or engagement with digital technology and Open Access (OA). This chapter considers an important attempt to tackle failing markets for scholarly monographs, and to enable the wider adoption of OA licenses for book-length works: the 2012 – 2014 Knowledge Unlatched pilot. Knowledge Unlatched is a bold attempt to reconfigure the market for specialist scholarly books: moving it beyond the sale of ‘content’ towards a model that supports the services valued by scholarly and wider communities in the context of digital possibility. Its success has powerful implications for the way we understand copyright’s role in the creative industries, and the potential for established institutions and infrastructure to support the open and networked dynamics of a digital age.

Silver nanoparticles (AgNPs) pose a high risk of exposure to the natural environment owing to their extensive usage in various consumer products. In the present study we attempted to understand the harmful effect of AgNPs at environmentally relevant low concentration levels (<= 1 ppm) towards two different freshwater bacterial isolates and their consortium. The standard plate count assay suggested that the AgNPs were toxic towards the fresh water bacterial isolates as well as the consortium, though toxicity was significantly reduced for the cells in the consortium. The oxidative stress assessment and membrane permeability studies corroborated with the toxicity data. The detailed electron microscopic studies suggested the cell degrading potential of the AgNPs, and the FT-IR studies confirmed the involvement of the surface groups in the toxic effects. No significant ion leaching from the AgNPs was observed at the applied concentration levels signifying the dominant role of the particle size, and size distribution in bacterial toxicity. The reduced toxicity for the cells in the consortium than the individual isolates has major significance in further studies on the ecotoxicity of the AgNPs. (C) 2014 Elsevier Inc.

O presente trabalho visa caracterizar os acidentes com envolvimento de motocicletas no perímetro urbano de Paranavaí-PR, em 2007, e estimar o impacto econômico das internações advindas destes, na perspectiva do Sistema Único de Saúde (SUS) e para o Seguro obrigatório que cobre danos pessoais causados por veículos automotores de via terrestre (DPVAT). Trata-se de um estudo transversal, retrospectivo, que se baseia em buscas e análises das bases de dados do Serviço integrado de atendimento ao trauma e emergência (SIATE), do DPVAT e do Sistema de informações sobre internações do SUS (SIH-SUS), com vias a análise das variáveis: gênero, idade, tipo de acidente, condição da vítima no acidente, mês da ocorrência, gravidade, frequência de internação hospitalar, custo, componentes de custo, óbitos e tempo médio de permanência no SUS. A busca ocorreu, primeiramente, no sistema do SIATE para conhecer todos os acidentados com envolvimento de motocicletas no perímetro urbano de Paranavaí, no ano de 2007. De posse desses nomes, as buscas seguintes ocorreram no sistema interno do DPVAT e no SIH-SUS. O profissional do SIATE, no momento da abordagem da ocorrência julga a gravidade da vítima conforme códigos, sendo 1 para ferimentos leves, 2 para graves sem risco à vida, 3, graves com risco à vida e 4, os óbitos. A população estudada constou de 655 vítimas (440 homens e 215 mulheres), com média de idade de 29,5 anos, sendo que 598 (91,3%) saíram lesionadas e 11 (1,7%) vieram a óbito. O condutor de motocicleta foi o mais acometido e o tipo de acidente mais comum aconteceu entre um automóvel e uma motocicleta. Com relação à frequência da internação hospitalar (pelo SUS, DPVAT ou ambos), foi, em média, de 27% (177 de 655). Do total de vítimas internadas verificou-se que 106 tiveram cobertura do DPVAT, 58 do SUS e 13 de ambos. As internações pelo DPVAT geraram um custo total de R$ 191.423,43, custo médio de R$ 1.608,60 por internação. Com relação aos custos das internações do SUS, os referidos acidentes geraram o pagamento de R$ 42.342,20, perfazendo a média de R$ 450,44 por AIH e de R$ 596,37 por paciente. O custo médio da internação dos acidentes de trânsito com envolvimento de motocicletas foi de R$ 1.321,00, sendo que para o código 1 foi de R$ 885,00, para o código 2 de R$ 1.377,00 e para o código 3 de R$ 2.034,00. Portanto, foi possível caracterizar os acidentes e chegar a estimativas de quanto se gasta com as internações advindas destes, além disso, este é um indicativo claro da necessidade de adotar políticas públicas que priorizem a aplicação dos recursos financeiros e humanos na redução dos acidentes e da sua gravidade.
