A European research roadmap for optimizing societal impact of big data on environment and energy efficiency
We present a roadmap to guide European research efforts towards a socially
responsible big data economy that maximizes the positive impact of big data in
environment and energy efficiency. The goal of the roadmap is to allow
stakeholders and the big data community to identify and meet big data
challenges, and to proceed with a shared understanding of the societal impact,
positive and negative externalities, and concrete problems worth investigating.
It builds upon a case study focused on the impact of big data practices in the
context of Earth Observation that reveals both positive and negative effects in
the areas of economy, society and ethics, legal frameworks and political
issues. The roadmap identifies European technical and non-technical priorities
in research and innovation to be addressed in the upcoming five years in order
to deliver societal impact, develop skills and contribute to standardization.Comment: 6 pages, 2 figures, 1 tabl
Unidata's Common Data Model mapping to the ISO 19123 Data Model
Access to real-time distributed Earth and Space Science (ESS) information is essential for enabling critical Decision Support Systems (DSS). Thus, data model interoperability between the ESS and DSS communities is a decisive achievement for enabling cyber-infrastructure which aims to serve important societal benefit areas. The ESS community is characterized by a certain heterogeneity, as far as data models are concerned. Recent spatial data infrastructures implement international standards for the data model in order to achieve interoperability and extensibility. This paper presents well-accepted ESS data models, introducing a unified data model called the Common Data Model (CDM). CDM mapping into the corresponding elements of the international standard coverage data model of ISO 19123 is presented and discussed at the abstract level. The mapping of CDM scientific data types to the ISO coverage model is a first step toward interoperability of data systems. This mapping will provide the abstract framework that can be used to unify subsequent efforts to define appropriate conventions along with explicit agreed-upon encoding forms for each data type. As a valuable case in point, the content mapping rules for CDM grid data are discussed addressing a significant example
Considerazioni sui casi di tumore nell’Area della Ricerca di Firenze del Consiglio Nazionale delle Ricerche
Recentemente, tra i dipendenti dell’Area della Ricerca di Firenze del Consiglio Nazionale delle Ricerche (CNR) presso il Polo Scientifico di Sesto Fiorentino si è verificato un numero preoccupante di casi di tumore. L’Azienda Sanitaria di Firenze (ASF) e l’Istituto per lo Studio e la Prevenzione Oncologica (ISPO) di Firenze, con l’interessamento dell’Azienda Regionale per la Protezione Ambientale della Toscana, hanno indagato la questione, concludendo che il numero di casi verificatisi non è statisticamente superiore alla media territoriale e che non è stata riscontrata la presenza di fattori di rischio ambientale.
Questo documento evidenzia svariati aspetti critici, sia nel merito che nel metodo, dell’indagine condotta, con particolare riferimento all’approfondimento statistico.
In conclusione, si ritiene che l’intervento di ASF-ISPO non costituisca un’indagine accurata e che sia stato insuffi- ciente e sbrigativo. Si raccomandano ulteriori approfondimenti e interventi di monitoraggio e prevenzione sul personale e sull’ambiente dell’Area CNR, del Polo Scientifico e della Piana in generale
Ethyl acetate extract from Cistus x incanus L. leaves enriched in myricetin and quercetin derivatives, inhibits inflammatory mediators and activates Nrf2/HO-1 pathway in LPS-stimulated RAW 264.7 macrophages.
Abstract
Cistus x incanus L. is a Mediterranean evergreen shrub used in folk medicine for the treatment of inflammatory disorders but the underlying mechanisms are not fully understood. We therefore investigated the anti-inflammatory effects of an ethyl acetate fraction (EAF) from C. x incanus L. leaves on lipopolysaccharide (LPS) activated RAW 264.7 macrophages. HPLC analysis revealed myricetin and quercetin derivatives to be the major compounds in EAF; EAF up to 1 µM of total phenolic content, was not cytotoxic and inhibited the mRNA expression of interleukin-6 (IL-6) and cyclooxygenase-2 (COX-2) (p < 0.05) and the production of prostaglandins E2 (PGE2) (p < 0.05). Meanwhile, EAF triggered the mRNA expression of interleukin-10 (IL-10) and elicited the nuclear translocation of nuclear factor erythroid 2-related factor 2 (Nrf2), as well as the expression of its main target gene, heme oxygenase-1 (HO-1) (p < 0.05). These data indicate that EAF attenuates experimental inflammation via the inhibition of proinflammatory mediators and at least in part, by the activation of Nrf2/HO-1 pathway. These effects are likely due to myricetin and quercetin derivatives but the role of other, less abundant components cannot be excluded. Further studies to confirm the relevance of our findings in animal models and to highlight the relative contribution of each component to the anti-inflammatory activity of EAF should be conducted
