Capabilities and skills to orchestrate innovation networks

Purpose – This study aims to present a theoretical analysis on the capabilities (at the organizational) andskills (at the individual level) of the hub organization (orchestrator) in an innovation network.Design/methodology/approach – The authors conducted literature reviews on the orchestration ofinnovation networks; and networking capabilities.Findings – This study presents a theoretical model and a research agenda.Originality/value – In interorganizational relations, a central actor can stand out the role of intentionally creating,extracting and distributing value in the network, generating gains for all members. Literature recognizes this set ofintentional and deliberate actions as the “orchestration” of resources in the network. Despite the increasing interestregarding the theme, the phases and specific capabilities for orchestration still lack further investigation

DIREITO REAL DE LAJE: UMA ANÁLISE DA SUA FUNÇÃO SOCIAL

O Direito Real de Laje veio a ser incluído no ordenamento jurídico brasileiro por meio da Medida Provisória nº 759/2016, a qual foi elaborada e publicada nos últimos dias do ano de 2016. Em junho de 2017 a referida Medida Provisória foi transformada em Lei, sendo assim promulgada a Lei 13.467/2017, a qual trouxe ao ordenamento, de forma definitiva, o Direito Real de Laje. Tal normativa traz ao ordenamento jurídico brasileiro a regulamentação dos denominados “Puxadinhos”, mais comuns nas áreas favelizadas da sociedade, onde o poder aquisitivo e o espaço disponível é menor. Assim, tendo em vista a regulamentação da moradia dessas famílias que residem, na maioria das vezes, nas áreas favelizadas, surge a questão da real função do Direito Real do Laje e qual a sua função social. Portanto o objetivo da presente pesquisa é fomentar o debate e trazer à baila as nuances do Direito Real de Laje e suas aplicações práticas no meio social, sendo necessário que esta análise ocorra sob o viés constitucional, a fim de que se possa verificar a sua função social

O Contágio da Crise do Subprime nos Índices Setoriais do Mercado Acionário Brasileiro: Uma Abordagem dos Modelos de Volatilidade Condicional Multivariados

Oscillations within the financial market during the subprime crisis caused an increase in volatility and a fall in asset prices, in addition to increasing the degree of normal market movements. This study analyzed the contagion effect of the international financial crisis on the Brazilian stock market indices upon studying the estimated covariance patterns between the Brazilian and American stock market indices. The empirical analysis was based on the multivariate BEKK-GARCH models. The results showed that the estimation of the covariance structure between 2007 and 2010 had clear evidence of contagion in the indices investigated: Electricity (IEE), Telecommunications (ITEL), Consumption (ICON), Industrial Sector (INDX), Real Estate (IMOB), and Financial (IFNC). During the period of the international financial crisis, there was an increase in the covariance between the American and Brazilian market indices. The IMOB and IFNC indices showed the highest contagions among all the ones analyzed, reflecting the losses of the civil construction industry along with internal and external credit scarcity.As oscilações no mercado financeiro durante a crise do subprime ocasionaram a elevação da volatilidade e queda dos preços dos ativos, além de elevar o grau dos movimentos comuns entre os mercados. Este trabalho analisou o efeito contágio da crise financeira internacional sobre os índices do mercado de ações do Brasil, a partir do estudo do padrão das covariâncias estimadas entre os índices do mercado acionário brasileiro e americano. A análise empírica foi baseada nos modelos multivariados GARCH-BEKK. Os resultados mostraram que a estrutura das covariâncias estimadas, entre os anos de 2007 e 2010, indicou claras evidências de contágio nos índices considerados. No período da crise financeira internacional, houve uma elevação da covariância entre os índices dos mercados norte-americano e brasileiro. Os Índices Imobiliário e Financeiro apresentaram os maiores contágios entre todos analisados, refletindo as perdas das indústrias de construção civil, somadas à escassez de crédito interno e externo

Prevalence of Burnout Syndrome in nursing professionals of basic health care

Objective: To estimate the prevalence of Burnout Syndrome among the Primary Health Care nurses in a city of Bahia Southwest. Methods: Cross-sectional study, conducted with 60 nursing professionals of primary care. We used a sociodemographic and occupational questionnaire, and the Maslach Burnout Inventory. Data were tabulated using SPSS, version 22.0, and analyzed using descriptive statistics. Results: The prevalence of Burnout Syndrome was 58,3% according to the criteria of Grunfeld et al, and 16,7% according to Ramirez et al., they have found high levels in the dimension depersonalization (48,3%). and low job satisfaction (56,6%). The prevalence of Burnout Syndrome in the study population was high, as was the high rate predisposition to develop this syndrome. Conclusions: The study pointed out the need to implement preventive and interventional measures to ensure a beneficial and promising health work environment

Covalent incorporation of diphenylanthracene in oxotriphenylhexanoate organogels as a quasi-solid photon upconversion matrix

Triplet-triplet annihilation photon upconversion (TTA-UC) in solid state assemblies are desirable since they can be easily incorporated into devices such as solar cells, thus utilizing more of the solar spectrum. Realizing this is, however, a significant challenge that must circumvent the need for molecular diffusion, poor exciton migration, and detrimental back energy transfer among other hurdles. Here, we show that the above-mentioned issues can be overcome using the versatile and easily synthesized oxotriphenylhexanoate (OTHO) gelator that allows covalent incorporation of chromophores (or other functional units) at well-defined positions. To study the self-assembly properties as well as its use as a TTA-UC platform, we combine the benchmark couple platinum octaethylporphyrin as a sensitizer and 9,10-diphenylanthracene (DPA) as an annihilator, where DPA is covalently linked to the OTHO gelator at different positions. We show that TTA-UC can be achieved in the chromophore-decorated gels and that the position of attachment affects the photophysical properties as well as triplet energy transfer and triplet-triplet annihilation. This study not only provides proof-of-principle for the covalent approach but also highlights the need for a detailed mechanistic insight into the photophysical processes underpinning solid state TTA-UC

AVALIAÇÃO DA CARGA DE TRABALHO EM GARÇONS DE UM RESTAURANTE EM NITERÓI UTILIZANDO O MÉTODO NASA-TLX

Sabendo que a preocupação com a carga de trabalho é uma área importante dentro da ergonomia, este estudo buscou avaliar a carga de trabalho nas atividades desempenhadas pelos garçons de um restaurante em Niterói. Para isso além do levantamento bibliográfico, foram feitas visitas ao local e aplicou-se o método NASA-TLX a partir de entrevistas destes trabalhadores com base em três questionários. Os resultados da avaliação de carga do trabalho demonstraram que os principais fatores de carga para os garçons são a demanda temporal e o seu desempenho nas suas funções e os de menor relevância são a demanda física e a demanda mental. Conclui-se que mais estudos sobre o assunto são necessários, mas o método NASA-TLX foi adequado para o que se objetivou aqui

Reprogramming of Trypanosoma cruzi metabolism triggered by parasite interaction with the host cell extracellular matrix.

Trypanosoma cruzi, the etiological agent of Chagas' disease, affects 8 million people predominantly living in socioeconomic underdeveloped areas. T. cruzi trypomastigotes (Ty), the classical infective stage, interact with the extracellular matrix (ECM), an obligatory step before invasion of almost all mammalian cells in different tissues. Here we have characterized the proteome and phosphoproteome of T. cruzi trypomastigotes upon interaction with ECM (MTy) and the data are available via ProteomeXchange with identifier PXD010970. Proteins involved with metabolic processes (such as the glycolytic pathway), kinases, flagellum and microtubule related proteins, transport-associated proteins and RNA/DNA binding elements are highly represented in the pool of proteins modified by phosphorylation. Further, important metabolic switches triggered by this interaction with ECM were indicated by decreases in the phosphorylation of hexokinase, phosphofructokinase, fructose-2,6-bisphosphatase, phosphoglucomutase, phosphoglycerate kinase in MTy. Concomitantly, a decrease in the pyruvate and lactate and an increase of glucose and succinate contents were detected by GC-MS. These observations led us to focus on the changes in the glycolytic pathway upon binding of the parasite to the ECM. Inhibition of hexokinase, pyruvate kinase and lactate dehydrogenase activities in MTy were observed and this correlated with the phosphorylation levels of the respective enzymes. Putative kinases involved in protein phosphorylation altered upon parasite incubation with ECM were suggested by in silico analysis. Taken together, our results show that in addition to cytoskeletal changes and protease activation, a reprogramming of the trypomastigote metabolism is triggered by the interaction of the parasite with the ECM prior to cell invasion and differentiation into amastigotes, the multiplicative intracellular stage of T. cruzi in the vertebrate host
