Intracultural diversity in a model of social dynamics

We study the consequences of introducing individual nonconformity in social interactions, based on Axelrod's model for the dissemination of culture. A constraint on the number of situations in which interaction may take place is introduced in order to lift the unavoidable ho mogeneity present in the final configurations arising in Axelrod's related models. The inclusion of this constraint leads to the occurrence of complex patterns of intracultural diversity whose statistical properties and spatial distribution are characterized by means of the concepts of cultural affinity and cultural cli ne. It is found that the relevant quantity that determines the properties of intracultural diversity is given by the fraction of cultural features that characterizes the cultural nonconformity of individuals.Comment: 7 pages, 2 tables, 6 figure

A importância da mensuração do resultado econômico para a gestão das instituições públicas

Trabalho de Conclusão de Curso apresentado ao Departamento Acadêmico de Ciências Contábeis da Fundação Universidade Federal de Rondônia, campus Professor Francisco Gonçalves Quiles, para obtenção do título de Bacharel em Ciências Contábeis. Orientadora: Prof.ª M.ª Nilza Duarte Aleixo de OliveiraA Lei n.º 4.320/64, artigo 85, prevê que os serviços de contabilidade nos entes públicos devem permitir analisar e interpretar os resultados econômicos. Contudo, a mesma não prevê um demonstrativo específico para se mensurar tal resultado. Visando atender a esse dispositivo legal, foi criado por Valmor Slomski um modelo de mensuração do resultado econômico em instituições públicas. Se produzir lucro econômico, o gestor público estará produzindo e distribuindo renda. Se produzir prejuízo econômico, a estrutura do agenciamento deverá ser revista. Com esse demonstrativo, atende-se ao artigo 85 da Lei n.º 4.320/64, demonstra-se a eficiência da administração pública no uso dos recursos públicos, e evidencia-se para a sociedade o valor do serviço público produzido pela entidade pública governamental ou não. O artigo foi desenvolvido com o objetivo geral de elaborar o Demonstrativo de Resultado Econômico de duas escolas públicas municipais de Ji-Paraná – RO, bem como demonstrar a importância do resultado alcançado para a sociedade. A metodologia utilizada foi de pesquisa bibliográfica, empregando-se, posteriormente, a pesquisa de campo com estudo de caso, para a coleta dos dados necessários à construção do Demonstrativo de Resultado Econômico das escolas públicas municipais Adão Valdir Lamota e Jandinei Cella. Os demonstrativos resultaram em prejuízo econômico nas duas escolas, notando-se claramente que os gastos com folha de pagamento consomem mais do que o valor de suas receitas econômicas. Esses prejuízos econômicos encontrados representam a ineficiência da administração pública no uso dos recursos públicos, além da não atenção devida à análise de custos pelos gestores públicos

Biomimetic Ca-P coatings Incorporating bisphosphonates produced on starch-based degradable biomaterials

In this study, sodium clodronate, a well-known therapeutic agent from the family of bisphosphonates (BPs), is incorporated in a biomimetic calcium phosphate (CaP) coating, previously formed on the surface of a starch-based biomaterial by a sodium silicate methodology, as a strategy to develop a site-specific drug delivery system for bone tissue regeneration applications. The effects on the resulting CaP coatings were evaluated in terms of morphology, chemistry, and structure. The dissolution of Ca and P from the coating and the release profiles of sodium clodronate was also assessed. As a preliminary approach, this first study also aimed at evaluating the effects of this BP on the viability of a human osteoblastic cell line since there is still little information available on the interaction between BPs and this type of cells. Sodium clodronate was successfully incorporated, at different doses, in the structure of a biomimetic CaP layer previously formed by a sodium silicate process. This type of BPs had a stimulatory effect on osteoblastic activity, particularly at the specific concentration of 0.32 mg/mL. It is foreseen that these coatings can, for instances, be produced on the surface of degradable polymers and then used for regulating the equilibrium on osteoblastic/osteoclastic activity, leading to a controlled regenerative effect at the interface between the biomaterial and bone

J-PLUS: A wide-field multi-band study of the M15 globular cluster. Evidence of multiple stellar populations in the RGB

The Javalambre Photometric Local Universe Survey (J-PLUS) provides wide field-of-view images in 12 narrow, intermediate and broad-band filters optimized for stellar photometry. Here we have applied J-PLUS data for the first time for the study of Galactic GCs using science verification data obtained for the very metal-poor GC M\,15. Our J-PLUS data provide low-resolution spectral energy distributions covering the near-UV to the near-IR, allowing us to search for MPs based on pseudo-spectral fitting diagnostics. J-PLUS CMDs are found to be particularly useful to search for splits in the sequences formed by the upper red giant branch (RGB) and asymptotic giant branch (AGB) stars. We interpret these split sequences as evidence for the presence of MPs. This demonstrates that the J-PLUS survey will have sufficient spatial coverage and spectral resolution to perform a large statistical study of GCs through multi-band photometry in the coming years.Comment: 11 pages, 11 figures.

Does IQ influence association between working memory and adhd symptoms in young adults?

Objective: This study examined the association between WM and ADHD symptoms in young adults and whether IQ-score influenced this association. Method: Data from the 1993 Pelotas (Brazil) Birth Cohort Study were analyzed (N = 2,845). Working memory and ADHD symptoms were collected at 22 years. IQ was examined at age 18. Poisson regression with robust variance was used to assess the associations between working memory and ADHD symptoms. We also evaluated whether IQ modified associations between working memory and ADHD symptoms. Results: Working memory was negatively associated with Inattention symptoms of ADHD. The association between working memory and hyperactivity-impulsivity symptoms of ADHD varied by IQ. Conclusions: This study provides new insights to theories about the relationship between WM and ADHD symptoms as well as the development of interventions aimed at improving the performance of WM in ADHD

Temporalidade descolonial em The Kissinger Project de Alfredo Jaar

A partir de uma análise em uma perspectiva descolonial da obra do artista chileno Alfredo Jaar, mais especificamente The Kissinger Project, Florencia San Martín revisita alguns fatos históricos relevantes para a América do Sul, entre as décadas de 1970 e 1980, quando os regimes ditatoriais militares dominavam os países da região. No processo, esses regimes contaram com a participação/intervenção estado-unidense, tendo Henry Kissinger, então secretário de Estado, como personalidade política mais proeminente na defesa dos interesses das corporações dos Estados Unidos. No entanto, como nos alerta San Martín, “o econômico, o político e o social operam em conexão um com o outro”. Neste sentido, a ditadura militar chilena tinha na “implementação do livre mercado” um fator destacado em sua agenda política. San Martín nos recorda ainda que, assim como a modernidade, também a descolonialidade é um projeto inacabado. (Resumo e palavras-chave elaborados pelos editores

Effect of fungal colonization on mechanical performance of cork

The industrialization of traditional processes relies on the scientific ability to understand the empirical evidence associated with traditional knowledge. Cork manufacturing includes one operation known as stabilization, where humid cork slabs are extensively colonized by fungi. The implications of fungal growth on the chemical quality of cork through the analysis of putative fungal metabolites have already been investigated. However, the effect of fungal growth on the mechanical properties of cork remains unexplored. This study investigated the effect of cork colonization on the integrity of the cork cell walls and their mechanical performance. Fungal colonization of cork by Chrysonilia sitophila, Mucor plumbeus Penicillium glabrum, P. olsonii, and Trichoderma longibrachiatum was investigated by microscopy. Growth occurred primarily on the surface of the cork pieces, but mycelium extended deeper into the cork layers, mostly via lenticular channels and by hyphal penetration of the cork cell wall. In this first report on cork decay in which specific correlation between fungal colonization and mechanical proprieties of the cork has been investigated, all colonizing fungi except C. sitophila, reduced cork strength, markedly altering its viscoelastic behaviour and reducing its Young’s modulus.IBET, ITQB,EVN-INIA,IGC, IST,CEF-ISA, Amorim and Irmaos (Sta.

Mosquito-Borne Viral Diseases: Control and Prevention in the Genomics Era

Mosquito-borne viral diseases are infections transmitted by the bite of infected mosquitoes. The burden of these diseases is highest in tropical and subtropical areas and they disproportionately affect the poorest populations. Since 2014, major outbreaks of dengue, chikungunya, yellow fever and Zika have afflicted populations and overwhelmed health systems in many countries. Distribution of mosquito-borne diseases is determined by complex demographic, environmental and social factors, causing diseases to emerge in countries where they were previously unknown. Coupling genomic diagnostics and epidemiology to innovative digital disease detection platforms raises the possibility of an open, global, digital pathogen surveillance system. Considering pathogen surveillance in mind, real-time sequencing, bioinformatics tools and the combination of genomic and epidemiological data from viral infections can give essential information for understanding the past and the future of an epidemic, making possible to establish an effective surveillance framework on tracking the spread of infections to other geographic regions

Tuberculose como marcador de iniquidades em um contexto de transformação socioespacial

OBJECTIVE This study aims to analyze the association between the incidence of tuberculosis and different socioeconomic indicators in a territory of intense transformation of the urban space. METHODS This is an ecological study, whose analysis units were the neighborhoods of the city of Itaboraí, state of Rio de Janeiro, Brazil. The data have been analyzed by generalized linear models. The response variable was incidence of tuberculosis from 2006 to 2011. The independent variables were the socio-demographic indicators. The spatial distribution of tuberculosis was analyzed with the elaboration of thematic maps. RESULTS The results have shown a significant association between the incidence of tuberculosis and variables that reflect different dimensions of living conditions, such as consumer goods, housing conditions and its surroundings, agglomeration of population, and income distribution. CONCLUSIONS The disproportionate incidence of tuberculosis in populations with worse living conditions highlights the persistence of socioeconomic determinants in the reproduction of the disease. Different municipal public sectors need to better articulate with local tuberculosis control programs to reduce the social burden of the disease.OBJETIVO Analisar a associação entre incidência de tuberculose e diferentes indicadores socioeconômicos em território em intensa transformação do espaço urbano. MÉTODOS Estudo ecológico, cujas unidades de análise foram os bairros do município de Itaboraí, RJ. Os dados foram analisados por modelos lineares generalizados. A variável resposta foi incidência de tuberculose de 2006 a 2011. As variáveis independentes foram os indicadores sociodemográficos. A distribuição espacial da tuberculose foi analisada por meio da elaboração de mapas temáticos. RESULTADOS Os resultados apontaram associação significativa entre a incidência de tuberculose e variáveis que refletem diferentes dimensões de condições de vida, como bens de consumo, condições de moradia e seu entorno, aglomeração populacional e distribuição de renda. CONCLUSÕES O acometimento desproporcional da tuberculose em grupos populacionais com piores condições de vida ressalta a persistência dos determinantes socioeconômicos na reprodução da doença. Faz-se necessária a melhor articulação de diferentes setores públicos municipais com o programa local de controle da tuberculose visando à redução da carga social da doença
