After being appointed "premier physician" in 1731, Pierre Chirac, thanks to his influence with the king, tried to realize an ambitious project. Inspired by the creation of an Academie de Chirurgie by the "premier surgeon", Chirac decided to creation an Académie de Médecine in Paris. Under his guidance, it was planned to collect opinions from all doctors of the kingdom in order to enhance global knowledge of disease, symptoms and treatments. However, threatened with the loss of its secular superiority, the Paris University Medical School immediately opposed the project. Although well advanced, the project was finally abandoned on Chirac's death.

New biostratigraphical data based on foraminifers, algae and pseudo-algae indicate that the limestone pebbles of the channelized polygenic conglomerates of the Migoumess formation contain Late Visean (V3b γ-V3c) assemblages. That confirms the Westphalian age attributed to this formation by Hollard [Zdt. Geol. Ges. 129 (1978) 495-512]. The Tournaisian age assigned to it by palynology [C. R. Acad. Sci. Paris, série II 310 (1990) 1573-1576] cannot be retained. The Tirhela formation, Late Visean and Serpukhovian (E1) in age, is coeval with the Akerchi formation [Berkhli, thèse d'État, 1999; Berkhli et al., J. Afr. Earth Sci. (accepté)]. The Idmarrach formation, mapped as a thrust sheet [C. R. Acad. Sci. Paris, série II 310 (1990) 1573-1576], is dated as Serpukhovian (E1) and its thrusting is consequently post-Serpukhovian. Palaeogeographic and geodynamic consequences are listed. To cite this article: M. Berkhli, D. Vachard, C. R. Geoscience 334 (2002) 67-72

1994-01-01
The IEEE standard 1596-1992, Scalable Coherent Interface (SCI) provides novel possibilities to build data acquisition systems for large and very high rate experiments in high energy physics. The RD24 project at CERN started two years ago to investigate applications of SCI to data acquisition at the Large Hadron Collider (LHC). As part of the RD24 project, simulation of large SCI-based data acquisition systems is performed by a simulator written in the object-oriented language MODSIM II. The goal of this paper is to investigate the difference between SCI switch- and SCI-based systems, and to study some of the design criteria for the SCI switch element to form the interconnection of large scale SCI-based data acquisition systems. 15 refs., 14 figs., 2 tabs

Shape-changing interfaces (SCI) are rapidly evolving and creating new interaction paradigms in human-computer interaction (HCI). However, empirical research in SCI is still bound to present technological limitations and existing prototypes can only show a limited number of potential applications...... for shape change. In this paper we attempt to broaden the pool of examples of what shape change may be good for by investigating SCI using Science Fiction (Sci-Fi) movies. We look at 340 Sci-Fi movies to identify instances of SCI and analyze their behavioral patterns and the context in which they are used....... The result of our analysis presents four emerging behavioral patterns of shape change: (1) Reconfiguration, (2) Transformation, (3) Adaptation, and (4) Physicalization. We report a selection of SCI instances from Sci-Fi movies, which show how these behavioral patterns model functionalities of shape change...

Evaluation for moments of a ratio with application to regression estimation
Doukhan, Paul; Lang, Gabriel
2008-01-01
Ratios of random variables often appear in probability and statistical applications. We aim to approximate the moments of such ratios under several dependence assumptions. Extending the ideas in Collomb [C. R. Acad. Sci. Paris 285 (1977) 289–292], we propose sharper bounds for the moments of randomly weighted sums and for the Lp-deviations from the asymptotic normal law when the central limit theorem holds. We indicate suitable applications in finance and censored data analysis and focus on t...

Full Text Available Ao estilo dos textos de Baudelaire sobre os flâneurs que caminhavam na cidade de Paris, descobrindo os símbolos da modernidade, este artigo narra a chegada de um estrangeiro à capital francesa no início do século XX e seu passeio pela cidade. Ao longo de um dia, ele tomará contato com as obras de importantes artistas como Toulouse-Lautrec, Murcha e Chéret, que desenharam cartazes para shows, embalagens de produtos, folhetos promocionais, entre outras manifestações artísticas exploradas pelo então nascente espírito moderno. À semelhança do romance de Umberto Eco, A misteriosa chama da rainha Loana, que reproduz imagens da cultura pop e erudita em meio à sua narrativa, o texto segue o formato de ensaio ilustrado, fundindo a ficção com os aspectos reais da Paris na efervescência da Belle Époque. A estrutura, portanto, rompe com os gêneros tradicionais dos artigos acadêmicos, apresentando conteúdo reflexivo por meios dos personagens e da trama engendrada. Palavras-chave: Paris; Belle Époque; modernidade; imagens; publicidade. ABSTRACT In the style of Baudelaire’s texts on the flâneurs who used to walk in the city of Paris, finding the symbols of modernity, this article narrates the ar- rival of a foreigner in the early 20th century in Paris, and his tour around the French capital. In the course of one day, he will be in contact with the works of important artists, such as Toulouse-Lautrec, Murcha and Chéret, who drew posters for shows, products’ packages, advertising leaflets, among other artistic manifestations, explored by the then rising modern spirit. Similar to Umberto Eco’s novel The mysterious flame of Queen Loana, which reproduces images of both pop and erudite culture in its narrative, the text follows the illustrated essay format, merging fiction and the real aspects of Paris’ effervescent Belle Époque. The structure, therefore, breaks free from the traditional genres of academic articles, presenting the

Tangent unit-vector fields: Nonabelian homotopy invariants and the Dirichlet energy
Majumdar, Apala
2009-10-01
Let O be a closed geodesic polygon in S2. Maps from O into S2 are said to satisfy tangent boundary conditions if the edges of O are mapped into the geodesics which contain them. Taking O to be an octant of S2, we evaluate the infimum Dirichlet energy, E (H), for continuous tangent maps of arbitrary homotopy type H. The expression for E (H) involves a topological invariant - the spelling length - associated with the (nonabelian) fundamental group of the n-times punctured two-sphere, π1 (S2 - {s1, ..., sn}, *). These results have applications for the theoretical modelling of nematic liquid crystal devices. To cite this article: A. Majumdar et al., C. R. Acad. Sci. Paris, Ser.

GHG monitoring over Paris megacity and Orléans forest
Te, Y. V.; Jeseck, P.; Zanon, T.; Boursier, C.; Janssen, C.; Deutscher, N. M.; Warneke, T.; Notholt, J.; Lac, C.; Dieudonné, E.; Lopez, M.; Schmidt, M.; Xueref-remy, I. C.

In a growing world with more than 7 billion inhabitants and big emerging countries such as China, Brazil and India, emissions of anthropogenic pollutants and greenhouse gases (GHGs) are increasing continuously. Their monitoring and control in megacities have become a major challenge for scientists and public health authorities in environmental research area. The ground-based Fourier transform spectrometer (QualAir FTS[a], model IFS 125HR) of the QualAir platform located in downtown Paris at University Pierre et Marie Curie (UPMC), is a scientific research instrument dedicated to the survey of greenhouse gases (GHGs) and urban air quality. Equipped with a sun-tracker, the remote sensing QualAir FTS relies on solar infrared absorption for monitoring trace gas concentrations and their variability in the Ile-de-France region[b]. Concentrations of atmospheric GHGs, especially CO2, CH4 and N2O, are retrieved by the radiative transfer model PROFFIT[c]. Because Paris is the third largest European megacity, the QualAir FTS can provide new and complementary measurements as compared to existing ground-based FTS network stations (NDACC and TCCON) located in unpolluted environments, such as the TCCON-Orléans station[d] situated in the forest of Orléans (100 km south of Paris). In the effort to integrate QualAir FTS into the TCCON network, simultaneous FTS measurements of GHGs at Paris and Orléans have been performed. We will emphasize on comparisons of CO2 from these two sites. Our comparison will be completed by high-resolved direct CO2 modeling outputs from the Meso-NH model, and ground in situ measurements at different sites (Orléans/Trainou, Paris/Jussieu, Paris/Eiffel Tower). Parts of the data were acquired in the framework of the French CO2-MEGAPARIS project[e, f], whose main goal is to quantify CO2 emissions from the Paris area. The present data intercomparison will help to reduce uncertainties in carbon cycle models and to better characterize regional GHG fluxes

Friedrich Creuzer (1771-1858 à l’Académie des Inscriptions et Belles-Lettres

Full Text Available La contribution donnera une vue d’ensemble des relations personnelles et culturelles qui ont déterminé la réception dans la culture française de l’œuvre Symbolik und Mythologie de Friedrich Creuzer (1771-1858. L’élection de Creuzer comme membre de l’Académie des Inscriptions et Belles-Lettres en 1825 y constituera l’épisode central qui s’inscrit dans un cadre plus large du « transfert culturel » franco-allemand.Pour sa réception en France, Sylvestre de Sacy, président de la Société Asiatique, jouait un rôle décisif. C’est surtout grâce à son initiative que Creuzer fut élu membre de l’Académie des Inscriptions où il devenait, en 1826, le successeur du fameux Friedrich August Wolf et fut accueilli au même moment que Wilhelm von Humboldt, une coïncidence qui porta à Creuzer une estime incontestable qu’en Allemagne, il lui manquait. La querelle de méthode que sa Symbolique avait provoquée en Allemagne y conduisit à une marginalisation dans la philologie classique officielle. De plus, il fut accusé de « cryptocatholicisme », de « trahison » de la foi protestante et, d’une façon implicite, d’adhésion à la maçonnerie. En France, jusqu’à sa réception à l’Académie, Creuzer n’était pas connu pour sa Symbolique, mais plutôt pour ses travaux sur l’historiographie antique et ses éditions de Cicéron. Pendant son séjour à l’Académie des Inscriptions à Paris en 1827, il s’efforçait, d’après ses propres notes autobiographiques, d’éviter des débats sur la mythologie ou la religion et de se présenter comme chercheur strictement historique. À Paris, il approfondit ses recherches orientales en entrant en contact avec Félix Lajard, Eugène Burnouf et Edgar Quinet. Creuzer y rencontra aussi son traducteur Jean Daniel Guigniaut qui allait travailler plus de 25 ans à la traduction et récriture de la Symbolique. La révision de Guigniaut eut une influence énorme dans la

A Duality Theory for Non-convex Problems in the Calculus of Variations
Bouchitté, Guy; Fragalà, Ilaria
2018-02-01
We present a new duality theory for non-convex variational problems, under possibly mixed Dirichlet and Neumann boundary conditions. The dual problem reads nicely as a linear programming problem, and our main result states that there is no duality gap. Further, we provide necessary and sufficient optimality conditions, and we show that our duality principle can be reformulated as a min-max result which is quite useful for numerical implementations. As an example, we illustrate the application of our method to a celebrated free boundary problem. The results were announced in Bouchitté and Fragalà (C R Math Acad Sci Paris 353(4):375-379, 2015).

Paris INDCs: will they achieve the goal of the Paris Climate Agreement?
Tribett, W. R.; Salawitch, R. J.; Hope, A. P.; Bennett, B.; Canty, T. P.
2016-12-01
We provide an overview of the Intended Nationally Determined Contributions (INDCs) submitted prior to the 21st meeting of the Conference of the Parties to the United Nations Framework Convention on Climate Change, which are the backbone of the Paris Climate Agreement. Two flavors of INDCs were submitted: unconditional (i.e., firm commitments) and conditional (commitments contingent on financial flow and/or technology transfer). Generally, the Paris INDCs extend to year 2030. However, achievement of either the target (1.5 °C warming) or upper limit (2.0 °C warming) of the Paris Agreement requires consideration of emissions out to 2060, due to the projected rise in energy demand, growing populations, and rising standards of living. We therefore project global carbon emissions out to year 2060, and compare to various RCP scenarios of IPCC (2013). These projections will be used to assess whether the target (1.5 °C warming) or upper limit (2.0 °) of the Paris Climate Agreement will be met.

Reveal genes functionally associated with ACADS by a network study.
Chen, Yulong; Su, Zhiguang
2015-09-15
Establishing a systematic network is aimed at finding essential human gene-gene/gene-disease pathway by means of network inter-connecting patterns and functional annotation analysis. In the present study, we have analyzed functional gene interactions of short-chain acyl-coenzyme A dehydrogenase gene (ACADS). ACADS plays a vital role in free fatty acid β-oxidation and regulates energy homeostasis. Modules of highly inter-connected genes in disease-specific ACADS network are derived by integrating gene function and protein interaction data. Among the 8 genes in ACADS web retrieved from both STRING and GeneMANIA, ACADS is effectively conjoined with 4 genes including HAHDA, HADHB, ECHS1 and ACAT1. The functional analysis is done via ontological briefing and candidate disease identification. We observed that the highly efficient-interlinked genes connected with ACADS are HAHDA, HADHB, ECHS1 and ACAT1. Interestingly, the ontological aspect of genes in the ACADS network reveals that ACADS, HAHDA and HADHB play equally vital roles in fatty acid metabolism. The gene ACAT1 together with ACADS indulges in ketone metabolism. Our computational gene web analysis also predicts potential candidate disease recognition, thus indicating the involvement of ACADS, HAHDA, HADHB, ECHS1 and ACAT1 not only with lipid metabolism but also with infant death syndrome, skeletal myopathy, acute hepatic encephalopathy, Reye-like syndrome, episodic ketosis, and metabolic acidosis. The current study presents a comprehensible layout of ACADS network, its functional strategies and candidate disease approach associated with ACADS network. Copyright © 2015 Elsevier B.V.

By almost any measure, the SciDAC community has come a long way since DOE launched the SciDAC program back in 2001. At the time, we were grappling with how to efficiently run applications on terascale systems (the November 2001 TOP500 list was led by DOE's ASCI White IBM system at Lawrence Livermore achieving 7.2 teraflop/s). And the results stemming from the first round of SciDAC projects were summed up in two-page reports. The scientific results were presented at annual meetings, which were by invitation only and typically were attended by about 75 researchers. Fast forward to 2009 and we now have SciDAC Review, a quarterly magazine showcasing the scientific computing contributions of SciDAC projects and related programs, all focused on presenting a comprehensive look at Scientific Discovery through Advanced Computing. That is also the motivation behind the annual SciDAC conference that in 2009 was held from June 14-18 in San Diego. The annual conference, which can also be described as a celebration of all things SciDAC, grew out those meetings organized in the early days of the program. In 2005, the meeting was held in San Francisco and attendance was opened up to all members of the SciDAC community. The schedule was also expanded to include a keynote address, plenary speakers and other features found in a conference format. This year marks the fifth such SciDAC conference, which now comprises four days of computational science presentations, multiple poster sessions and, since last year, an evening event showcasing simulations and modeling runs resulting from SciDAC projects. The fifth annual SciDAC conference was remarkable on several levels. The primary purpose, of course, is to showcase the research accomplishments resulting from SciDAC programs in particular and computational science in general. It is these accomplishments, represented in 38 papers and 52 posters, that comprise this set of conference proceedings. These proceedings can stand alone as

SCI based data acquisition architectures
International Nuclear Information System (INIS)
Bogaerts, J.A.C.; Divia, R.; Renardy, J.F.
1992-01-01
This paper discusses the Scalable Coherent Interface (SCI), an IEEE proposed standard (P1596) for interconnecting multiprocessor systems. The standard defines point to point connections between nodes, which can be processors, memories or I/O devices. Networks containing a maximum of 64K nodes with a bandwidth of one Gbyte/s between nodes, may be constructed. SCI is an attractive candidate to serve as a backbone for high speed, large volume data acquisition systems such as required by future experiments at the proposed Large Hadron Collider (LHC) at CERN. Work has started to simulate SCI based architectures for data acquisition systems. The simulation program proved to be a useful tool to study SCI systems. First results are reported on a model of a large LHC experiment containing over 1000 nodes

Produtivismo acadêmico baseado em uma perspectiva habermasiana
Directory of Open Access Journals (Sweden)
Fábio Vizeu
Full Text Available Resumo Este artigo argumenta que a questão da ética na prática acadêmica deve ser tratada com o mesmo cuidado adotado em outras práticas profissionais. Na verdade, uma dificuldade no debate sobre ética na prática acadêmica é desconsiderar que esta também consiste em uma prática social condicionada pelos mesmos problemas que a sociedade contemporânea enfrenta, especialmente em sua dimensão econômica. Nesse sentido, discute-se o utilitarismo na prática acadêmica com base no referencial da ética discursiva de Jürgen Habermas, explorando algumas inquietações sobre o produtivismo acadêmico brasileiro. Metodologicamente, usa-se o ensaio teórico como procedimento argumentativo, visando à construção de um texto menos formal e mais provocativo, instigando a reflexão e o debate, no meio, das questões pontuadas. Especificamente, observamos o problema da valorização quantitativa da produção sem a consideração da qualidade do trabalho acadêmico associado à tentativa de mensuração da atividade acadêmica, além da falta da devida reflexão sobre os valores ético-morais que circunscrevem a atividade científico-educacional no Brasil. Por último, para ilustrar a perspectiva apresentada, recorremos a situações hipotéticas da prática acadêmica e fazemos inferências sobre quatro correlações entre a orientação pragmática e questões éticas, considerando o constructo habermasiano da ação estratégica.

Its location on the Seine River, at a strategic crossroads of land and river routes, has been the key to its expansion since the Parisii tribe first settled here in the 3rd century BC. Paris is an alluring city boasting many monumental landmarks, such as the Cathedral of Notre Dame, the Louvre, and the Eiffel Tower. Its beautiful gardens, world-class cuisine, high fashion, sidewalk cafes, and intellectual endeavors are well known. The city's cultural life is centered on the Left Bank of the Seine, while business and commerce dominate the Right Bank. The image is located at 48.8 degrees north latitude and 2.3 degrees east longitude. In figure 1, the 4 enlarged areas zoom in to some of the major buildings. In the UPPER LEFT, the Eiffel Tower and its shadow are seen. Based on the length of the shadow and the solar elevation angle of 59 degrees, we can calculate its height as 324 m (1054 ft), compared to its actual height of 303 m (985 ft). In the UPPER RIGHT, the Arc de Triomphe is at the center of the Place de L'etoile, from which radiate 12 major boulevards. In the LOWER LEFT is the Tuileries Garden and the Louvre Museum art its eastern end. In the LOWER RIGHT is the Invalides, the burial place and monument of Napoleon Bonaparte. The U.S. science team is located at NASA's Jet Propulsion Laboratory, Pasadena, Calif. The Terra mission is part of NASA's Science Mission Directorate.

It takes a village to perform a petascale computation—domain scientists, applied mathematicians, computer scientists, computer system vendors, program managers, and support staff—and the village was assembled during 24-28 June 2007 in Boston's Westin Copley Place for the third annual Scientific Discovery through Advanced Computing (SciDAC) 2007 Conference. Over 300 registered participants networked around 76 posters, focused on achievements and challenges in 36 plenary talks, and brainstormed in two panels. In addition, with an eye to spreading the vision for simulation at the petascale and to growing the workforce, 115 participants—mostly doctoral students and post-docs complementary to the conferees—were gathered on 29 June 2007 in classrooms of the Massachusetts Institute of Technology for a full day of tutorials on the use of SciDAC software. Eleven SciDAC-sponsored research groups presented their software at an introductory level, in both lecture and hands-on formats that included live runs on a local BlueGene/L. Computation has always been about garnering insight into the behavior of systems too complex to explore satisfactorily by theoretical means alone. Today, however, computation is about much more: scientists and decision makers expect quantitatively reliable predictions from simulations ranging in scale from that of the Earth's climate, down to quarks, and out to colliding black holes. Predictive simulation lies at the heart of policy choices in energy and environment affecting billions of lives and expenditures of trillions of dollars. It is also at the heart of scientific debates on the nature of matter and the origin of the universe. The petascale is barely adequate for such demands and we are barely established at the levels of resolution and throughput that this new scale of computation affords. However, no scientific agenda worldwide is pushing the petascale frontier on all its fronts as vigorously as SciDAC. The breadth of this conference

The second annual Scientific Discovery through Advanced Computing (SciDAC) Conference was held from June 25-29, 2006 at the new Hyatt Regency Hotel in Denver, Colorado. This conference showcased outstanding SciDAC-sponsored computational science results achieved during the past year across many scientific domains, with an emphasis on science at scale. Exciting computational science that has been accomplished outside of the SciDAC program both nationally and internationally was also featured to help foster communication between SciDAC computational scientists and those funded by other agencies. This was illustrated by many compelling examples of how domain scientists collaborated productively with applied mathematicians and computer scientists to effectively take advantage of terascale computers (capable of performing trillions of calculations per second) not only to accelerate progress in scientific discovery in a variety of fields but also to show great promise for being able to utilize the exciting petascale capabilities in the near future. The SciDAC program was originally conceived as an interdisciplinary computational science program based on the guiding principle that strong collaborative alliances between domain scientists, applied mathematicians, and computer scientists are vital to accelerated progress and associated discovery on the world's most challenging scientific problems. Associated verification and validation are essential in this successful program, which was funded by the US Department of Energy Office of Science (DOE OS) five years ago. As is made clear in many of the papers in these proceedings, SciDAC has fundamentally changed the way that computational science is now carried out in response to the exciting challenge of making the best use of the rapid progress in the emergence of more and more powerful computational platforms. In this regard, Dr. Raymond Orbach, Energy Undersecretary for Science at the DOE and Director of the OS has stated

A significant proportion (estimates range from 16 to 74%) of patients with spinal cord injury (SCI) have concomitant traumatic brain injury (TBI), and the combination often produces difficulties in planning and implementing rehabilitation strategies and drug therapies. For example, many of the drugs used to treat SCI may interfere with cognitive rehabilitation, and conversely drugs that are used to control seizures in TBI patients may undermine locomotor recovery after SCI. The current paper presents an experimental animal model for combined SCI and TBI to help drive mechanistic studies of dual diagnosis. Rats received a unilateral SCI (75 kdyn) at C5 vertebral level, a unilateral TBI (2.0 mm depth, 4.0 m/s velocity impact on the forelimb sensori-motor cortex), or both SCI+TBI. TBI was placed either contralateral or ipsilateral to the SCI. Behavioral recovery was examined using paw placement in a cylinder, grooming, open field locomotion, and the IBB cereal eating test. Over 6weeks, in the paw placement test, SCI+contralateral TBI produced a profound deficit that failed to recover, but SCI+ipsilateral TBI increased the relative use of the paw on the SCI side. In the grooming test, SCI+contralateral TBI produced worse recovery than either lesion alone even though contralateral TBI alone produced no observable deficit. In the IBB forelimb test, SCI+contralateral TBI revealed a severe deficit that recovered in 3 weeks. For open field locomotion, SCI alone or in combination with TBI resulted in an initial deficit that recovered in 2 weeks. Thus, TBI and SCI affected forelimb function differently depending upon the test, reflecting different neural substrates underlying, for example, exploratory paw placement and stereotyped grooming. Concurrent SCI and TBI had significantly different effects on outcomes and recovery, depending upon laterality of the two lesions. Recovery of function after cervical SCI was retarded by the addition of a moderate TBI in the contralateral

More attention was paid to the anti-tumor activity of Rhizoma Paridis (RP) recently, of which the wild resource was decreased significantly. This study was aimed to elucidate the chemical characteristics of Paris fargesii var. brevipetala (PFB) that may be administrated as alternate resource of legal RP. A HPLC-ELSD method was established to characterize the steroid saponins in rhizomes of PFB and two legal Paris species [Paris polyphylla var. chinensis (PPC) and P. polyphylla var. yunnanensis (PPY)] in Chinese Pharmacopoeia (CP). Ten saponins (paris saponins I, II, V, VI, VII, H, gracillin and other three paris saponins) were involved as standards. The results indicated that PFB contained pennogenyl saponins as the main components with small amounts of diosgenin saponins. The total contents of the detected saponins in PFB ranged from 9.12mg/g to 85.33mg/g. Nine of the twelve PFB samples own a total content of paris saponins I, II, VI, and VII more than 6.0mg/g (meeting the standard of CP 2010 edition). Principal Component Analysis (PCA) and Partial Least Squares-Discriminate Analysis (PLS-DA) both confirmed the fact that saponin profiles of PFB, PPC and PPY were different from each other. In addition, paris saponin H (Ps H), the predominant saponin of PFB (>50%), was tested in vitro to evaluate its cytotoxic activities on HepG2, A549, RPE and L929 cells with a positive control of Cisplatin. Ps H showed a remarkable cytotoxic activity on A549 cells with an IC(50) value of 1.53±0.08μg/mL. Copyright © 2012 Elsevier B.V. All rights reserved.

Climate Justice and the Paris Agreement
International Nuclear Information System (INIS)
Michelot, Agnes
2016-01-01
The concept of climate justice has been, for the first time, used in an international agreement - namely, the Paris Agreement. But this recognition of the notion of climate justice is extremely restricted by the very way it is formulated. Preamble of the Paris Agreement 'notes' that climate justice is recognized by 'certain cultures'. Does it mean that particular and concrete stakes of climate justice of the pre-COP21 agenda have been recognized or, on the contrary, that the notion so introduced is actually an empty shell without any genuine legal perspective? Considering this uncertainty, it appears relevant to analyze the Paris Agreement through the claims of various groups and coalitions, which influenced the COP21 negotiations

2013-07-01
Postal surveys. To confirm the factor structure of the Spanish version of the MPI-SCI (MPI-SCI-S, Multidimensional Pain Inventory in the SCI population) and to test its internal consistency and construct validity in a Spanish population. Guttmann Institute, Barcelona, Spain. The MPI-SCI-S along with Spanish measures of pain intensity (Numerical Rating Scale), pain interference (Brief Pain Inventory), functional independence (Functional Independence Measure), depression (Beck Depression Inventory), locus of control (Multidimensional health Locus of Control), support (Functional Social Support Questionnaire (Duke-UNC)), psychological well-being (Psychological Global Well-Being Index) and demographic/injury characteristics were assessed in persons with spinal cord injury (SCI) and chronic pain (n=126). Confirmatory factor analysis suggested an adequate factor structure for the MPI-SCI-S. The internal consistency of the MPI-SCI-S subscales ranged from acceptable (r=0.66, Life Control) to excellent (r=0.94, Life Interference). All MPI-SCI-S subscales showed adequate construct validity, with the exception of the Negative and Solicitous Responses subscales. The Spanish version of the MPI-SCI is adequate for evaluating chronic pain impact following SCI in a Spanish-speaking population. Future studies should include additional measures of pain-related support in the Spanish-speaking SCI population.

Conhecimento dos acadêmicos e profissionais da fisioterapia sobre dor: uma revisão sistemática
Directory of Open Access Journals (Sweden)
Alan Carlos Nery dos Santos
2017-08-01
Full Text Available Estudos demonstram que acadêmicos e profissionais da fisioterapia apresentam limitações no conhecimento sobre diversos aspectos do tema “dor”. Isso pode implicar em abordagens inadequadas e em maior sofrimento dos pacientes. Assim, objetivou-se revisar estudos que investigaram o conhecimento de acadêmicos e profissionais da fisioterapia sobre dor, bem como os que propuseram estratégias para modificar tal conhecimento. Trata-se de uma revisão sistemática, e foram consultadas as bases de dados EBSCOhost, LILACS, PubMed, REDALYC e SciELO, por meio do cruzamento das palavras-chave: “pain”, “knowledge”, “education”, “curriculum”, “physical therapy specialty” e os seus correspondentes em português. Foram considerados elegíveis os estudos observacionais ou experimentais que analisaram o conhecimento sobre aspectos clínicos, fisiopatológicos e manejo da dor. Também foram elegíveis os que testaram estratégias para modificar o conhecimento sobre dor. A triagem pelos títulos e resumo resultou em 84 estudos. Contudo, apenas cinco foram incluídos. Esses analisaram o conhecimento sobre aspectos gerais da dor, sendo publicados entre 2003 e 2016. Apenas 60% dos estudos investigaram participantes da fisioterapia, sendo que 100% deles verificaram o conhecimento por meio de questionários autoaplicáveis. Quatro estudos utilizaram questionários validados. Somente 20% testaram estratégias para modificar o conhecimento sobre dor. Os resultados desta revisão indicam que o tema “dor” é abordado apenas como subtema complementar, o que, embora permita o aprendizado, não tem sido suficiente para garanti-lo. Profissionais da fisioterapia apresentam inconsistência entre o conhecimento teórico e os seus papeis no manuseio e na assistência humanizada da dor. Estratégias de ensino-aprendizagem ativas podem aprimorar o conhecimento acadêmico sobre dor.

SCI implementation study for LHCb data acquisition
Müller, H
1998-01-01
This paper proposes the use of SCI 1 as a scalable standard to implement the eventbuilder network between the Readout-Units and the Subfarm Controllers of LHCb. SCI [Ref 1] allows for a memory bus-like interconnection between the data sources and the CPU farm, this implies that sources can directly write data to event-buffers in the farm. This data-driven eventbuilding is enhanced by DMA engines as part of the SCI adapters at the source buffers. In general, data may be either written from the sources (event driven DMA for the full readout) or pulled from the destination (demand-driven DMA for the phased readout). A mixture of both readout architectures is possible, a second level push and a third level pull scheme could simultaneously coexist across the same physical network. Sources and destinations are interconnected via very high bandwidth SCI rings ( 4-8 Gbit/s). By using SCI switches, bandwidth scaling up to any required throughput is possible. The functionalities of a Readout Unit (RU) and a Subfarm Con...

We plan to observe solar neutrons at Mt. Sierra Negra (4,600 m above sea level) in Mexico using the SciBar detector. This project is named the SciBar Cosmic Ray Telescope (SciCRT). The main aims of the SciCRT project are to observe solar neutrons to study the mechanism of ion acceleration on the surface of the sun and to monitor the anisotropy of galactic cosmic-ray muons. The SciBar detector, a fully active tracker, is composed of 14,848 scintillator bars, whose dimension is 300 cm × 2.5 cm × 1.3 cm. The structure of the detector enables us to obtain the particle trajectory and its total deposited energy. This information is useful for the energy reconstruction of primary neutrons and particle identification. The total volume of the detector is 3.0 m × 3.0 m × 1.7 m. Since this volume is much larger than the solar neutron telescope (SNT) in Mexico, the detection efficiency of the SciCRT for neutrons is highly enhanced. We performed the calibration of the SciCRT at Instituto Nacional de Astrofisica, Optica y Electronica (INAOE) located at 2,150 m above sea level in Mexico in 2012. We installed the SciCRT at Mt. Sierra Negra in April 2013 and calibrated this detector in May and August 2013. We started continuous observation in March 2014. In this paper, we report the detector performance as a solar neutron telescope and the current status of the SciCRT.

Experiences using SciPy for computer vision research
Energy Technology Data Exchange (ETDEWEB)
Eads, Damian R [Los Alamos National Laboratory; Rosten, Edward J [Los Alamos National Laboratory
2008-01-01
SciPy is an effective tool suite for prototyping new algorithms. We share some of our experiences using it for the first time to support our research in object detection. SciPy makes it easy to integrate C code, which is essential when algorithms operating on large data sets cannot be vectorized. The universality of Python, the language in which SciPy was written, gives the researcher access to a broader set of non-numerical libraries to support GUI development, interface with databases, manipulate graph structures. render 3D graphics, unpack binary files, etc. Python's extensive support for operator overloading makes SciPy's syntax as succinct as its competitors, MATLAB, Octave, and R. More profoundly, we found it easy to rework research code written with SciPy into a production application, deployable on numerous platforms.

A millennium approach to data acquisition: SCI and PCI
International Nuclear Information System (INIS)
Mueller, Hans; Bogaerts, A.; Lindenstruth, V.
1996-01-01
The international SCI standard IEEE/ANSI 1596 a is on its way to become the computer interconnect of the year 2000 since for a first time, low latency desktop multiprocessing and cluster computing can be implemented at low cost. The PCI bus is todays's dominating local bus extension for all major computer platforms as well as buses like VMEbus. PCI is a self configuring memory and I/O system for peripheral components with a hierarchical architecture. SCI is a scalable, bus-like interconnect for distributed processors and memories. It allows for optionally coherent data caching and assures error free data delivery. First measurement with commercial SCI products (SBUS-SCI) confirm simulations that SCI can handle even the highest data rates of LHC experiments. The event builder layer for a millennium very high rate DAQ system can therefore be viewed as a SCI network (bridges, cables and switches) interfaced between PCI buses on the front end (VME b ) side and on the processor farm Multi-CPU) side. Such a combination of SCI and PCI enables PCI-PCI memory access, transparently across SCI. It also allows for a novel, low level trigger technique: the trigger algorithm can access VME data buffers with bus-like latencies like local memory, full data transfers become redundant. The first prototype of a PCI-SCI bridge for DAQ is presented as starting point for a test system with built-in scalability. (author)

To describe the domain structure and calibration of the Spinal Cord Injury Functional Index for samples using Assistive Technology (SCI-FI/AT) and report the initial psychometric properties of each domain. Cross sectional survey followed by computerized adaptive test (CAT) simulations. Inpatient and community settings. A sample of 460 adults with traumatic spinal cord injury (SCI) stratified by level of injury, completeness of injury, and time since injury. None SCI-FI/AT RESULTS: Confirmatory factor analysis (CFA) and Item response theory (IRT) analyses identified 4 unidimensional SCI-FI/AT domains: Basic Mobility (41 items) Self-care (71 items), Fine Motor Function (35 items), and Ambulation (29 items). High correlations of full item banks with 10-item simulated CATs indicated high accuracy of each CAT in estimating a person's function, and there was high measurement reliability for the simulated CAT scales compared with the full item bank. SCI-FI/AT item difficulties in the domains of Self-care, Fine Motor Function, and Ambulation were less difficult than the same items in the original SCI-FI item banks. With the development of the SCI-FI/AT, clinicians and investigators have available multidimensional assessment scales that evaluate function for users of AT to complement the scales available in the original SCI-FI.

Welcome to Seattle and the 2008 SciDAC Conference. This conference, the fourth in the series, is a continuation of the PI meetings we first began under SciDAC-1. I would like to start by thanking the organizing committee, and Rick Stevens in particular, for organizing this year's meeting. This morning I would like to look briefly at SciDAC, to give you a brief history of SciDAC and also look ahead to see where we plan to go over the next few years. I think the best description of SciDAC, at least the simulation part, comes from a quote from Dr Ray Orbach, DOE's Under Secretary for Science and Director of the Office of Science. In an interview that appeared in the SciDAC Review magazine, Dr Orbach said, `SciDAC is unique in the world. There isn't any other program like it anywhere else, and it has the remarkable ability to do science by bringing together physical scientists, mathematicians, applied mathematicians, and computer scientists who recognize that computation is not something you do at the end, but rather it needs to be built into the solution of the very problem that one is addressing'. Of course, that is extended not just to physical scientists, but also to biological scientists. This is a theme of computational science, this partnership among disciplines, which goes all the way back to the early 1980s and Ken Wilson. It's a unique thread within the Department of Energy. SciDAC-1, launched around the turn of the millennium, created a new generation of scientific simulation codes. It advocated building out mathematical and computing system software in support of science and a new collaboratory software environment for data. The original concept for SciDAC-1 had topical centers for the execution of the various science codes, but several corrections and adjustments were needed. The ASCR scientific computing infrastructure was also upgraded, providing the hardware facilities for the program. The computing facility that we had at that time was the big 3

Hausdorff dimension of exponential parameter rays and their endpoints
International Nuclear Information System (INIS)
Bailesteanu, Mihai; Balan, Horia Vlad; Schleicher, Dierk
2008-01-01
We investigate the set I of parameters κ for which the singular value of z map e z + κ converges to ∞. The set I consists of uncountably many parameter rays, plus landing points of some of these rays (Förster et al 2008 Proc Am. Math. Soc. 136 at press (Preprint math.DS/0311427)). We show that the parameter rays have Hausdorff dimension 1, which implies (Qiu 1994 Acta Math. Sin. (N.S.) 10 362–8) that the ray endpoints in I alone have dimension 2. Analogous results were known for dynamical planes of exponential maps (Karpińska 1999 C. R. Acad. Sci. Paris Sér. I: Math. 328 1039–44; Schleicher and Zimmer 2003 J. Lond. Math.

The myriad challenges of the Paris Agreement
Mitchell, Dann; Allen, Myles R.; Hall, Jim W.; Muller, Benito; Rajamani, Lavanya; Le Quéré, Corinne
2018-05-01
The much awaited and intensely negotiated Paris Agreement was adopted on 12 December 2015 by the Parties to the United Nations Framework Convention on Climate Change. The agreement set out a more ambitious long-term temperature goal than many had anticipated, implying more stringent emissions reductions that have been under-explored by the research community. By its very nature a multidisciplinary challenge, filling the knowledge gap requires not only climate scientists, but the whole Earth system science community, as well as economists, engineers, lawyers, philosophers, politicians, emergency planners and others to step up. To kick start cross-disciplinary discussions, the University of Oxford's Environmental Change Institute focused its 25th anniversary conference upon meeting the challenges of the Paris Agreement for science and society. This theme issue consists of review papers, opinion pieces and original research from some of the presentations within that meeting, covering a wide range of issues underpinning the Paris Agreement. This article is part of the theme issue `The Paris Agreement: understanding the physical and social challenges for a warming world of 1.5°C above pre-industrial levels'.

Orgasm and SCI: what do we know?
Alexander, Marcalee; Marson, Lesley
2018-06-01
narrative review OBJECTIVES: To determine the percentage of persons with SCI able to achieve orgasm and ejaculation, the associations between ejaculation and orgasm and the subjective and autonomic findings during these events, and the potential benefits with regards to spasticity. Two American medical centers METHODS: Data bases were searched for the terms orgasm and SCI and ejaculation and SCI. Search criteria were human studies published in English from 1990 to 12/2/2016. Approximately 50% of sexually active men and women report orgasmic ability after SCI. There is a relative inability of persons with complete lower motor neuron injuries affecting the sacral segments to achieve orgasm. Time to orgasm is longer in persons with SCIs than able-bodied (AB) persons. With orgasm, elevated blood pressure (BP) occurs after SCI in a similar fashion to AB persons. With penile vibratory stimulation and electroejaculation, BP elevation is common and prophylaxis is recommended in persons with injuries at T6 and above. Dry orgasm occurs approximately 13% of times in males. Midodrine, vibratory stimulation, clitoral vacuum suction, and 4-aminopyridine may improve orgasmic potential. Depending on level and severity of injury, persons with SCIs can achieve orgasm. Sympathetically mediated changes occur during sexual response with culmination at orgasm. Future research should address benefits of orgasm. Additionally, inherent biases associated with studying orgasm must be considered.

Our previous study found that PARIS (ZNF746) transcriptionally suppressed transketolase (TKT), a key enzyme in pentose phosphate pathway (PPP) in the substantia nigra (SN) of AAV-PARIS injected mice. In this study, we revealed that PARIS overexpression reprogrammed glucose metabolic pathway, leading to the increment of glycolytic proteins along with TKT reduction in the SN of AAV-PARIS injected mice. Knock-down of TKT in differentiated SH-SY5Y cells led to an increase of glycolytic enzymes and decrease of PPP-related enzymes whereas overexpression of TKT restored PARIS-mediated glucose metabolic shift, suggesting that glucose metabolic alteration by PARIS is TKT-dependent. Inhibition of PPP by either PARIS overexpression or TKT knock-down elevated the level of H 2 O 2 , and diminished NADPH and GSH levels, ultimately triggering the induction of HIF-1α, a master activator of glycolysis. In addition, TKT inhibition by stereotaxic injection of oxythiamine demonstrated slight decrement of dopaminergic neurons (DNs) in SN but not cortical neurons in the cortex, suggesting that TKT might be a survival factor of DNs. In differentiated SH-SY5Y, cell toxicity by GFP-PARIS was partially restored by introduction of Flag-TKT and siRNA-HIF-1α. We also observed the increase of HIF-1α and glycolytic hexokinase 2 in the SN of Parkinson's disease patients. Taken together, these results suggest that PARIS accumulation might distort the balance of glucose metabolism, providing clues for understanding mechanism underlying selective DNs death by PARIS.

Full Text Available How signals from fatty acid metabolism are translated into changes in food intake remains unclear. Previously we reported that mice with a genetic inactivation of Acads (acyl-coenzyme A dehydrogenase, short-chain, the enzyme responsible for mitochondrial beta-oxidation of C4-C6 short-chain fatty acids (SCFAs, shift consumption away from fat and toward carbohydrate when offered a choice between diets. In the current study, we sought to indentify candidate genes and pathways underlying the effects of SCFA oxidation deficiency on food intake in Acads-/- mice.We performed a transcriptional analysis of gene expression in brain tissue of Acads-/- and Acads+/+ mice fed either a high-fat (HF or low-fat (LF diet for 2 d. Ingenuity Pathway Analysis revealed three top-scoring pathways significantly modified by genotype or diet: oxidative phosphorylation, mitochondrial dysfunction, and CREB signaling in neurons. A comparison of statistically significant responses in HF Acads-/- vs. HF Acads+/+ (3917 and Acads+/+ HF vs. LF Acads+/+ (3879 revealed 2551 genes or approximately 65% in common between the two experimental comparisons. All but one of these genes were expressed in opposite direction with similar magnitude, demonstrating that HF-fed Acads-deficient mice display transcriptional responses that strongly resemble those of Acads+/+ mice fed LF diet. Intriguingly, genes involved in both AMP-kinase regulation and the neural control of food intake followed this pattern. Quantitative RT-PCR in hypothalamus confirmed the dysregulation of genes in these pathways. Western blotting showed an increase in hypothalamic AMP-kinase in Acads-/- mice and HF diet increased, a key protein in an energy-sensing cascade that responds to depletion of ATP.Our results suggest that the decreased beta-oxidation of short-chain fatty acids in Acads-deficient mice fed HF diet produces a state of energy deficiency in the brain and that AMP-kinase may be the cellular energy

On 26-30 June 2005 at the Grand Hyatt on Union Square in San Francisco several hundred computational scientists from around the world came together for what can certainly be described as a celebration of computational science. Scientists from the SciDAC Program and scientists from other agencies and nations were joined by applied mathematicians and computer scientists to highlight the many successes in the past year where computation has led to scientific discovery in a variety of fields: lattice quantum chromodynamics, accelerator modeling, chemistry, biology, materials science, Earth and climate science, astrophysics, and combustion and fusion energy science. Also highlighted were the advances in numerical methods and computer science, and the multidisciplinary collaboration cutting across science, mathematics, and computer science that enabled these discoveries. The SciDAC Program was conceived and funded by the US Department of Energy Office of Science. It is the Office of Science's premier computational science program founded on what is arguably the perfect formula: the priority and focus is science and scientific discovery, with the understanding that the full arsenal of `enabling technologies' in applied mathematics and computer science must be brought to bear if we are to have any hope of attacking and ultimately solving today's computational Grand Challenge problems. The SciDAC Program has been in existence for four years, and many of the computational scientists funded by this program will tell you that the program has given them the hope of addressing their scientific problems in full realism for the very first time. Many of these scientists will also tell you that SciDAC has also fundamentally changed the way they do computational science. We begin this volume with one of DOE's great traditions, and core missions: energy research. As we will see, computation has been seminal to the critical advances that have been made in this arena.

PINK1 Primes Parkin-Mediated Ubiquitination of PARIS in Dopaminergic Neuronal Survival
Directory of Open Access Journals (Sweden)
Yunjong Lee
2017-01-01
Full Text Available Mutations in PTEN-induced putative kinase 1 (PINK1 and parkin cause autosomal-recessive Parkinson’s disease through a common pathway involving mitochondrial quality control. Parkin inactivation leads to accumulation of the parkin interacting substrate (PARIS, ZNF746 that plays an important role in dopamine cell loss through repression of proliferator-activated receptor gamma coactivator-1-alpha (PGC-1α promoter activity. Here, we show that PARIS links PINK1 and parkin in a common pathway that regulates dopaminergic neuron survival. PINK1 interacts with and phosphorylates serines 322 and 613 of PARIS to control its ubiquitination and clearance by parkin. PINK1 phosphorylation of PARIS alleviates PARIS toxicity, as well as repression of PGC-1α promoter activity. Conditional knockdown of PINK1 in adult mouse brains leads to a progressive loss of dopaminergic neurons in the substantia nigra that is dependent on PARIS. Altogether, these results uncover a function of PINK1 to direct parkin-PARIS-regulated PGC-1α expression and dopaminergic neuronal survival.

Wartime Paris, cirrhosis mortality, and the ceteris paribus assumption.
Fillmore, Kaye Middleton; Roizen, Ron; Farrell, Michael; Kerr, William; Lemmens, Paul
2002-07-01
This article critiques the ceteris paribus assumption, which tacitly sustains the epidemiologic literature's inference that the sharp decline in cirrhosis mortality observed in Paris during the Second World War derived from a sharp constriction in wine consumption. Paris's wartime circumstances deviate substantially from the "all else being equal" assumption, and at least three other hypotheses for the cirrhosis decline may be contemplated. Historical and statistical review. Wartime Paris underwent tumultuous changes. Wine consumption did decline, but there were, as well, a myriad of other changes in diet and life experience, many involving new or heightened hardships, nutritional, experiential, institutional, health and mortality risks. Three competing hypotheses are presented: (1) A fraction of the candidates for cirrhosis mortality may have fallen to more sudden forms of death; (2) alcoholics, heavy drinkers and Paris's clochard subpopulation may have been differentially likely to become removed from the city's wartime population, whether by self-initiated departure, arrest and deportation, or death from other causes, even murder; and (3) there was mismeasurement in the cirrhosis mortality decline. The alcohol-cirrhosis connection provided the template for the alcohol research effort (now more than 20 years old) aimed at re-establishing scientific recognition of alcohol's direct alcohol-problems-generating associations and causal responsibilities. In a time given to reports of weaker associations of the alcohol-cirrhosis connection, the place and importance of the Paris curve in the wider literature, as regards that connection, remains. For this reason, the Paris findings should be subjected to as much research scrutiny as they undoubtedly deserve.

Retrospective database review. To compare lengths of stay (LOS), pressure ulcers and readmissions to the acute care hospital of patients admitted to the inpatient rehabilitation facility (IRF) from a model spinal cord injury (SCI) trauma center or from a non-SCI acute hospital. Only sparse data exist comparing the status of patients admitted to IRF from a model SCI trauma center or from a non-SCI acute hospital. Acute care, IRF and total LOS were compared between patients transferred to IRF from the SCI center (n=78) and from non-SCI centers (n=131). The percentages of pressure ulcers on admission to IRF and transfer back to acute care were also compared. Patients admitted to IRF from the SCI trauma center (SCI TC) had significantly shorter (P=0.01) acute care LOS and total LOS compared with patients admitted from non-SCI TCs. By neurological category, acute-care LOS was less for all groups admitted from the SCI center, but statistically significant only for tetraplegia. There was no significant difference in the incidence of readmissions to acute care from IRF. More patients from non-SCI centers (34%) than SCI centers (12%) had pressure ulcers (PSCI TCs before transfer to IRF can significantly lower acute-care LOS or total LOS and incidence of pressure ulcers compared with non-SCI TCs. Patients admitted to IRF from SCI TCs are no more likely to be sent back to an acute hospital than those from non-SCI TCs.

Full Text Available Seven species of amphibians and reptiles were observed in eleven Sites of Community Importance (SCI of the Lodi Province (NW Italy. Distribution and relative abundance of amphibians appeared more variable than reptiles. Some species of conservation concern as R. latastei were influenced by habitat physiognomy, i.e. the surface of wooded areas are important in predict presence and relative abundance of this species. SCI with wider surfaces and higher habitat heterogeneity included higher number of species. Species richness, here considered as a raw index of biodiversity value and community quality, was significantly related to SCI area and habitat heterogeneity; since this significant positive relation is confirmed both for amphibians and reptiles we suggest that, in planning of natural areas, priority must be retained for biotopes able to host the higher number of species.

Good morning. Welcome to Boston, the home of the Red Sox, Celtics and Bruins, baked beans, tea parties, Robert Parker, and SciDAC 2007. A year ago I stood before you to share the legacy of the first SciDAC program and identify the challenges that we must address on the road to petascale computing—a road E E Cummins described as `. . . never traveled, gladly beyond any experience.' Today, I want to explore the preparations for the rapidly approaching extreme scale (X-scale) generation. These preparations are the first step propelling us along the road of burgeoning scientific discovery enabled by the application of X- scale computing. We look to petascale computing and beyond to open up a world of discovery that cuts across scientific fields and leads us to a greater understanding of not only our world, but our universe. As part of the President's America Competitiveness Initiative, the ASCR Office has been preparing a ten year vision for computing. As part of this planning the LBNL together with ORNL and ANL hosted three town hall meetings on Simulation and Modeling at the Exascale for Energy, Ecological Sustainability and Global Security (E3). The proposed E3 initiative is organized around four programmatic themes: Engaging our top scientists, engineers, computer scientists and applied mathematicians; investing in pioneering large-scale science; developing scalable analysis algorithms, and storage architectures to accelerate discovery; and accelerating the build-out and future development of the DOE open computing facilities. It is clear that we have only just started down the path to extreme scale computing. Plan to attend Thursday's session on the out-briefing and discussion of these meetings. The road to the petascale has been at best rocky. In FY07, the continuing resolution provided 12% less money for Advanced Scientific Computing than either the President, the Senate, or the House. As a consequence, many of you had to absorb a no cost extension for your

Post Paris and November 8, 2016
Busalacchi, A. J.
2016-12-01
COP 21 in Paris, as historic as it was, established the necessary, but not the sufficient. The signatories to the landmark Paris accord are a coalition of the willing, but their pledges are only as good as the sustained will of individual countries to adhere to their commitments. The U.S. presidential election has demonstrated how easily uncertainty can be added. Even if all countries abide by the Paris climate agreement, capping global mean temperatures to 2oC will likely require net zero greenhouse gas emissions by 2085 and substantial negative emissions over the long term. Before the Paris agreement was finished, it was clear that the pledged emission cuts by 2030 would not be sufficient in and of themselves, to stay under 2oC. Given the accumulation of greenhouse gases to date, limiting warming to a maximum of 2oC would require bending the curve of global emissions by 2020, i.e., over the next four years. If the past is a prologue, without even taking into account an emergence from the global recession, we stand a realistic chance of blowing right past the 2oC target. What, then, are the challenges going forward? Is 2oC a real goal that is attainable, or is it a stretch goal? Meeting a 2oC target is a function of when mitigation begins in earnest, the rate of mitigation, and the rate and amount of carbon sequestration. What are the implications of this trade space? While much effort has been put into designing a climate observing system from a science perspective, relatively little thought has been put into determining what observations are needed to support policy decisions, mitigation, and verify the Intended Nationally Determined Contributions that resulted from the Paris Agreement. If 2oC is a stretch goal, intellectual honesty requires that we consider mitigation and adaptation in tandem, and not as either/or. Similarly, even with all its attendant ethical dilemmas, it is important to thoroughly study geoengineering so that policy makers have a robust

GeoSciML and EarthResourceML Update, 2012
Richard, S. M.; Commissionthe Management; Application Inte, I.
2012-12-01
CGI Interoperability Working Group activities during 2012 include deployment of services using the GeoSciML-Portrayal schema, addition of new vocabularies to support properties added in version 3.0, improvements to server software for deploying services, introduction of EarthResourceML v.2 for mineral resources, and collaboration with the IUSS on a markup language for soils information. GeoSciML and EarthResourceML have been used as the basis for the INSPIRE Geology and Mineral Resources specifications respectively. GeoSciML-Portrayal is an OGC GML simple-feature application schema for presentation of geologic map unit, contact, and shear displacement structure (fault and ductile shear zone) descriptions in web map services. Use of standard vocabularies for geologic age and lithology enables map services using shared legends to achieve visual harmonization of maps provided by different services. New vocabularies have been added to the collection of CGI vocabularies provided to support interoperable GeoSciML services, and can be accessed through http://resource.geosciml.org. Concept URIs can be dereferenced to obtain SKOS rdf or html representations using the SISSVoc vocabulary service. New releases of the FOSS GeoServer application greatly improve support for complex XML feature schemas like GeoSciML, and the ArcGIS for INSPIRE extension implements similar complex feature support for ArcGIS Server. These improved server implementations greatly facilitate deploying GeoSciML services. EarthResourceML v2 adds features for information related to mining activities. SoilML provides an interchange format for soil material, soil profile, and terrain information. Work is underway to add GeoSciML to the portfolio of Open Geospatial Consortium (OGC) specifications.

Full Text Available Paris is one of the most important capitals of the middle age. Actually, this city is universecity. Namely, Paris was remembered as a univercity, education center and art and architecture center. Paris appeared differently from the other cities. Here was an important city that East culture and West culture mixed with each other. In its environment, there were cities that have a traditional structure. It carries all the facilities of the city structure in the later middle ages. Namely, Paris is remembered firstly, while city structure is described. Like Chretien de Troyes described, Paris had the culture that made France as the first heritage of Roma and Greek. Paris is a colourful city. Perhaps, France had the most crowd population because of these facilities of Paris. Generally, undoubtedly, these facilities had a big role about the development of France civilization in the 13th century. So, in this study, we will study to introduce Paris with social-economic and culturel angles and give its appearance in the later middle ages.

The Spinal Cord Injury--Quality of Life (SCI-QOL) measurement system was developed to address the shortage of relevant and psychometrically sound patient reported outcome (PRO) measures available for clinical care and research in spinal cord injury (SCI) rehabilitation. Using a computer adaptive testing (CAT) approach, the SCI-QOL builds on the Patient Reported Outcomes Measurement Information System (PROMIS) and the Quality of Life in Neurological Disorders (Neuro-QOL) initiative. This initial manuscript introduces the background and development of the SCI-QOL measurement system. Greater detail is presented in the additional manuscripts of this special issue. Classical and contemporary test development methodologies were employed. Qualitative input was obtained from individuals with SCI and clinicians through interviews, focus groups, and cognitive debriefing. Item pools were field tested in a multi-site sample (n=877) and calibrated using item response theory methods. Initial reliability and validity testing was performed in a new sample of individuals with traumatic SCI (n=245). Five Model SCI System centers and one Department of Veterans Affairs Medical Center across the United States. Adults with traumatic SCI. n/a n/a The SCI-QOL consists of 19 item banks, including the SCI-Functional Index banks, and 3 fixed-length scales measuring physical, emotional, and social aspects of health-related QOL (HRQOL). The SCI-QOL measurement system consists of psychometrically sound measures for individuals with SCI. The manuscripts in this special issue provide evidence of the reliability and initial validity of this measurement system. The SCI-QOL also links to other measures designed for a general medical population.

Parkin-interacting substrate (PARIS), a member of the family of Krüppel-associated box (KRAB)-containing zinc-finger transcription factors, is a substrate of the ubiquitin E3 ligase parkin. PARIS represses the expression of peroxisome proliferator-activated receptor γ coactivator-1α (PGC-1α), although the underlying mechanisms remain largely unknown. In the present study, we demonstrate that PARIS can be SUMOylated, and its SUMOylation plays a role in the repression of PGC-1a promoter activity. Protein inhibitor of activated STAT y (PIASy) was identified as an interacting protein of PARIS and shown to enhance its SUMOylation. PIASy repressed PGC-1a promoter activity, and this effect was attenuated by PARIS in a manner dependent on its SUMOylation status. Co-expression of SUMO-1 with PIASy completely repressed PGC-1a promoter activity independently of PARIS expression. PARIS-mediated PGC-1a promoter repression depended on the activity of histone deacetylases (HDAC), whereas PIASy repressed the PGC-1a promoter in an HDAC-independent manner. Taken together, these results suggest that PARIS and PIASy modulate PGC-1a gene transcription through distinct molecular mechanisms. -- Highlights: •PARIS can be SUMOylated in vivo and in vitro. •SUMOylation of PARIS functions in the repression of PGC-1a promoter activity. •PIASy interacts with PARIS and enhances its SUMOylation. •PIASy influences PARIS-mediated repression of PGC-1a promoter activity.

The website Sci-Hub enables users to download PDF versions of scholarly articles, including many articles that are paywalled at their journal's site. Sci-Hub has grown rapidly since its creation in 2011, but the extent of its coverage has been unclear. Here we report that, as of March 2017, Sci-Hub's database contains 68.9% of the 81.6 million scholarly articles registered with Crossref and 85.1% of articles published in toll access journals. We find that coverage varies by discipline and publisher, and that Sci-Hub preferentially covers popular, paywalled content. For toll access articles, we find that Sci-Hub provides greater coverage than the University of Pennsylvania, a major research university in the United States. Green open access to toll access articles via licit services, on the other hand, remains quite limited. Our interactive browser at https://greenelab.github.io/scihub allows users to explore these findings in more detail. For the first time, nearly all scholarly literature is available gratis to anyone with an Internet connection, suggesting the toll access business model may become unsustainable. © 2018, Himmelstein et al.

Plagio e integridad académica en Alemania
Directory of Open Access Journals (Sweden)
2016-07-01
Full Text Available Alemania es quizá uno de los países europeos que, ya desde el siglo XVIII, ha mantenido un debate público más intenso sobre prácticas científicas y académicas deshonestas, relacionadas especialmente con tesis doctorales. Este debate fue especialmente productivo a finales del siglo XIX, dando lugar desde entonces, para evitar estas prácticas inaceptables, a la obligatoriedad de publicar todas las tesis doctorales, como requisito previo a la expedición del título de doctor por cualquier universidad alemana. Este trabajo analiza los avances más importantes en plagio e integridad académica en Alemania, especialmente después del escándalo surgido en 2011 a raíz del plagio de la tesis doctoral del Ministro de Defensa Guttenberg, como son la creación de una eficaz metodología colaborativa de investigación del plagio en trabajos científicos o académicos utilizando Internet y las redes sociales, materializada en la Wiki «VroniPlag». También se describe someramente en este trabajo la consolidación definitiva de la figura del «Defensor de la Ciencia», como instrumento de ámbito nacional para prevenir, gestionar y combatir la deshonestidad científica, aparte de la publicación en 2013 de una nueva versión del manual de referencia al respecto «Sicherung guter wissenschaftlicher Praxis». Por último se analizan las conclusiones de la experiencia alemana relacionada con la ética académica, también desde una perspectiva histórica, pues sus recientes logros y avances pueden servir de referencia a otros países europeos.

To examine the ability of the Spinal Cord Injury-Functional Index/Assistive Technology (SCI-FI/AT) measure to detect change in persons with spinal cord injury (SCI). Multisite longitudinal (12-mo follow-up) study. Nine SCI Model Systems programs. Adults (N=165) with SCI enrolled in the SCI Model Systems database. Not applicable. SCI-FI/AT computerized adaptive test (CAT) (Basic Mobility, Self-Care, Fine Motor Function, Wheelchair Mobility, and/or Ambulation domains) completed at discharge from rehabilitation and 12 months after SCI. For each domain, effect size estimates and 95% confidence intervals were calculated for subgroups with paraplegia and tetraplegia. The demographic characteristics of the sample were as follows: 46% (n=76) individuals with paraplegia, 76% (n=125) male participants, 57% (n=94) used a manual wheelchair, 38% (n=63) used a power wheelchair, 30% (n=50) were ambulatory. For individuals with paraplegia, the Basic Mobility, Self-Care, and Ambulation domains of the SCI-FI/AT detected a significantly large amount of change; in contrast, the Fine Motor Function and Wheelchair Mobility domains detected only a small amount of change. For those with tetraplegia, the Basic Mobility, Fine Motor Function, and Self-Care domains detected a small amount of change whereas the Ambulation item domain detected a medium amount of change. The Wheelchair Mobility domain for people with tetraplegia was the only SCI-FI/AT domain that did not detect significant change. SCI-FI/AT CAT item banks detected an increase in function from discharge to 12 months after SCI. The effect size estimates for the SCI-FI/AT CAT vary by domain and level of lesion. Findings support the use of the SCI-FI/AT CAT in the population with SCI and highlight the importance of multidimensional functional measures.

Methodology for the development and calibration of the SCI-QOL item banks.
Tulsky, David S; Kisala, Pamela A; Victorson, David; Choi, Seung W; Gershon, Richard; Heinemann, Allen W; Cella, David
2015-05-01
To develop a comprehensive, psychometrically sound, and conceptually grounded patient reported outcomes (PRO) measurement system for individuals with spinal cord injury (SCI). Individual interviews (n=44) and focus groups (n=65 individuals with SCI and n=42 SCI clinicians) were used to select key domains for inclusion and to develop PRO items. Verbatim items from other cutting-edge measurement systems (i.e. PROMIS, Neuro-QOL) were included to facilitate linkage and cross-population comparison. Items were field tested in a large sample of individuals with traumatic SCI (n=877). Dimensionality was assessed with confirmatory factor analysis. Local item dependence and differential item functioning were assessed, and items were calibrated using the item response theory (IRT) graded response model. Finally, computer adaptive tests (CATs) and short forms were administered in a new sample (n=245) to assess test-retest reliability and stability. A calibration sample of 877 individuals with traumatic SCI across five SCI Model Systems sites and one Department of Veterans Affairs medical center completed SCI-QOL items in interview format. We developed 14 unidimensional calibrated item banks and 3 calibrated scales across physical, emotional, and social health domains. When combined with the five Spinal Cord Injury--Functional Index physical function banks, the final SCI-QOL system consists of 22 IRT-calibrated item banks/scales. Item banks may be administered as CATs or short forms. Scales may be administered in a fixed-length format only. The SCI-QOL measurement system provides SCI researchers and clinicians with a comprehensive, relevant and psychometrically robust system for measurement of physical-medical, physical-functional, emotional, and social outcomes. All SCI-QOL instruments are freely available on Assessment CenterSM.

Full Text Available El uso de la tecnología provoca cambios sociales. Esto incluye el trabajo en el ámbito universitario en donde está cambiando tanto la forma de ejercer la docencia como la forma de aprender y se requiere conocer el efecto del uso de la tecnología sobre el rendimiento del alumnado. En este trabajo se investigó la incidencia del uso de Internet sobre el éxito académico del alumnado de cinco universidades de Ecuador. Se levantó una muestra aleatoria de 4.697 personas y se las categorizó en perfiles de uso de Internet para actividades académicas y para entretenimiento, utilizando análisis factorial y análisis clúster. Las categorías resultantes se utilizaron como variables independientes en modelos de regresión logística multinomial que buscaban determinar si el uso de Internet tenía incidencia sobre el éxito académico. Los resultados muestran que quienes realizan actividades interactivas con pares y profesores o quienes utilizan de forma balanceada las distintas herramientas de Internet tienden a un mayor éxito académico que aquellos que solo buscan información. En lo referente al entretenimiento, se encontró una incidencia positiva del uso de Internet sobre el éxito académico. Los estudiantes que realizan descargas de contenido de audio, video y software, y quienes utilizan todas las posibilidades de entretenimiento, presentan menor tendencia a suspender que los estudiantes que utilizan mínimamente Internet. En cuanto al género se presentan diferencias en los usos académicos y de entretenimiento.

SCI Longitudinal Aging Study: 40 Years of Research.
Krause, James S; Clark, Jillian M R; Saunders, Lee L
2015-01-01
The Spinal Cord Injury (SCI) Longitudinal Aging Study was initiated in 1973 and has conducted 8 assessments over the past 40 years. It was designed to help rehabilitation professionals understand the life situation of people with SCI, but it has developed into the most long-standing study of aging and SCI and has resulted in over 50 publications. Our purpose was to provide a detailed history of the study, response patterns, utilization of measures, and a summary of key findings reported in the literature. Five participant samples have been incorporated over the 40 years, with enrollment in 1973, 1984, 1993 (2 samples), and 2003. A total of 2,208 participants have completed 6,001 assessments, with a particularly large number of assessments among those who are more than 40 years post injury (n = 349). The overall results have indicated changing patterns of outcomes over time as persons with SCI age, with some notable declines in participation and health. There has been a survivor effect whereby persons who are more active, well-adjusted, and healthier live longer. This study has several important features that are required for longitudinal research including (a) consistency of follow-up, (b) consistency of measures over time, (c) addition of new participant samples to counteract attrition, and (d) inclusion of a large number of individuals who have reached aging milestones unparalleled in the literature. Data from this study can inform the literature on the natural course of aging with SCI.

SciServer Compute brings Analysis to Big Data in the Cloud
Raddick, Jordan; Medvedev, Dmitry; Lemson, Gerard; Souter, Barbara
2016-06-01
SciServer Compute uses Jupyter Notebooks running within server-side Docker containers attached to big data collections to bring advanced analysis to big data "in the cloud." SciServer Compute is a component in the SciServer Big-Data ecosystem under development at JHU, which will provide a stable, reproducible, sharable virtual research environment.SciServer builds on the popular CasJobs and SkyServer systems that made the Sloan Digital Sky Survey (SDSS) archive one of the most-used astronomical instruments. SciServer extends those systems with server-side computational capabilities and very large scratch storage space, and further extends their functions to a range of other scientific disciplines.Although big datasets like SDSS have revolutionized astronomy research, for further analysis, users are still restricted to downloading the selected data sets locally - but increasing data sizes make this local approach impractical. Instead, researchers need online tools that are co-located with data in a virtual research environment, enabling them to bring their analysis to the data.SciServer supports this using the popular Jupyter notebooks, which allow users to write their own Python and R scripts and execute them on the server with the data (extensions to Matlab and other languages are planned). We have written special-purpose libraries that enable querying the databases and other persistent datasets. Intermediate results can be stored in large scratch space (hundreds of TBs) and analyzed directly from within Python or R with state-of-the-art visualization and machine learning libraries. Users can store science-ready results in their permanent allocation on SciDrive, a Dropbox-like system for sharing and publishing files. Communication between the various components of the SciServer system is managed through SciServer‘s new Single Sign-on Portal.We have created a number of demos to illustrate the capabilities of SciServer Compute, including Python and R scripts

SciDAC has had a major impact on computational beam dynamics and the design of particle accelerators. Particle accelerators-which account for half of the facilities in the DOE Office of Science Facilities for the Future of Science 20 Year Outlook-are crucial for US scientific, industrial, and economic competitiveness. Thanks to SciDAC, accelerator design calculations that were once thought impossible are now carried routinely, and new challenging and important calculations are within reach. SciDAC accelerator modeling codes are being used to get the most science out of existing facilities, to produce optimal designs for future facilities, and to explore advanced accelerator concepts that may hold the key to qualitatively new ways of accelerating charged particle beams.

Analysis of Sci-Hub downloads of computer science papers
Directory of Open Access Journals (Sweden)
Andročec Darko
2017-07-01
Full Text Available The scientific knowledge is disseminated by research papers. Most of the research literature is copyrighted by publishers and avail- able only through paywalls. Recently, some websites offer most of the recent content for free. One of them is the controversial website Sci-Hub that enables access to more than 47 million pirated research papers. In April 2016, Science Magazine published an article on Sci-Hub activity over the period of six months and publicly released the Sci-Hub’s server log data. The mentioned paper aggregates the view that relies on all downloads and for all fields of study, but these findings might be hiding interesting patterns within computer science. The mentioned Sci-Hub log data was used in this paper to analyse downloads of computer science papers based on DBLP’s list of computer science publications. The top downloads of computer science papers were analysed, together with the geographical location of Sci-Hub users, the most downloaded publishers, types of papers downloaded, and downloads of computer science papers per publication year. The results of this research can be used to improve legal access to the most relevant scientific repositories or journals for the computer science field.

Women's Sexual Health and Reproductive Function After SCI.
Courtois, Frédérique; Alexander, Marcalee; McLain, Amie B Jackson
2017-01-01
Sexual function and to a lesser extent reproduction are often disrupted in women with spinal cord injuries (SCI), who must be educated to better understand their sexual and reproductive health. Women with SCI are sexually active; they can use psychogenic or reflexogenic stimulation to obtain sexual pleasure and orgasm. Treatment should consider a holistic approach using autonomic standards to describe remaining sexual function and to assess both genital function and psychosocial factors. Assessment of genital function should include thoracolumbar dermatomes, vulvar sensitivity (touch, pressure, vibration), and sacral reflexes. Self-exploration should include not only clitoral stimulation, but also stimulation of the vagina (G spot), cervix, and nipples conveyed by different innervation sources. Treatments may consider PDE5 inhibitors and flibanserin on an individual basis, and secondary consequences of SCI should address concerns with spasticity, pain, incontinence, and side effects of medications. Psychosocial issues must be addressed as possible contributors to sexual dysfunctions (eg, lower self-esteem, past sexual history, depression, dating habits). Pregnancy is possible for women with SCI; younger age at the time of injury and at the time of pregnancy being significant predictors of successful pregnancy, along with marital status, motor score, mobility, and occupational scores. Pregnancy may decrease the level of functioning (eg, self-care, ambulation, upper-extremity tasks), may involve complications (eg, decubitus ulcers, weight gain, urological complications), and must be monitored for postural hypotension and autonomic dysreflexia. Taking into consideration the physical and psychosocial determinants of sexuality and childbearing allows women with SCI to achieve positive sexual and reproductive health.

2018-05-01
Retrospective, single centre cohort study. To determine factors associated with ventilator weaning success and failure in patients with acute spinal cord injury (SCI); determine length of time and attempts required to wean from the ventilator successfully and determine the incidence of pneumonia. BG Klinikum Hamburg, Level 1 trauma centre, SCI Department, Germany. From 2010 until 2017, 165 consecutive patients with cervical SCI, initially dependent on a ventilator, were included and weaned discontinuously via tracheal cannula. Data related to anthropometric details, neurological injury, respiratory outcomes, and weaning parameters were prospectively recorded in a database and retrospectively analysed. Seventy-nine percent of all patients were successfully weaned from ventilation. Average duration of the complete weaning process was 37 days. Ninety-one percent of the successfully weaned patients completed this on first attempt. Age (>56 years), level of injury (C4 and/or above), vital capacity (25 kg/m 2 ), and chronic obstructive pulmonary disease (COPD) significantly decreased the chance of successful weaning. These factors also correlated with a higher number of weaning attempts. High level of injury, older age, and reduced vital capacity also increased the duration of the weaning process. Patients with low vital capacity and concurrent therapy with Baclofen and Dantrolene showed higher rates of pneumonia. We conclude that mentioned factors are associated with weaning outcome and useful for clinical recommendations and patient counselling. These data further support the complexity of ventilator weaning in the SCI population due to associated complications, therefore we recommend conducting weaning of patients with SCI on intensive or intermediate care units (ICU/IMCU) in specialised centres.

ScienceDirect through SciVerse: a new way to approach Elsevier.
Bengtson, Jason
2011-01-01
SciVerse is the new combined portal from Elsevier that services their ScienceDirect collection, SciTopics, and their Scopus database. Using SciVerse to access ScienceDirect is the specific focus of this review. Along with advanced keyword searching and citation searching options, SciVerse also incorporates a very useful image search feature. The aim seems to be not only to create an interface that provides broad functionality on par with other database search tools that many searchers use regularly but also to create an open platform that could be changed to respond effectively to the needs of customers.

The World-Climate-Summit 2016 in Paris agreed to exacerbated goals for climate protection. This paper will scrutinize whether Germany can comply with its Paris-obligations by continuing the ongoing German ''Energiewende''. The result is clear-cut: The German ''Energiewende'' is inadequate. Due to the cap-and-trade system of the EU the ''Energiewende'' can in no way contribute to climate protection.

The fourth annual Scientific Discovery through Advanced Computing (SciDAC) Conference was held June 13-18, 2008, in Seattle, Washington. The SciDAC conference series is the premier communitywide venue for presentation of results from the DOE Office of Science's interdisciplinary computational science program. Started in 2001 and renewed in 2006, the DOE SciDAC program is the country's - and arguably the world's - most significant interdisciplinary research program supporting the development of advanced scientific computing methods and their application to fundamental and applied areas of science. SciDAC supports computational science across many disciplines, including astrophysics, biology, chemistry, fusion sciences, and nuclear physics. Moreover, the program actively encourages the creation of long-term partnerships among scientists focused on challenging problems and computer scientists and applied mathematicians developing the technology and tools needed to address those problems. The SciDAC program has played an increasingly important role in scientific research by allowing scientists to create more accurate models of complex processes, simulate problems once thought to be impossible, and analyze the growing amount of data generated by experiments. To help further the research community's ability to tap into the capabilities of current and future supercomputers, Under Secretary for Science, Raymond Orbach, launched the Innovative and Novel Computational Impact on Theory and Experiment (INCITE) program in 2003. The INCITE program was conceived specifically to seek out computationally intensive, large-scale research projects with the potential to significantly advance key areas in science and engineering. The program encourages proposals from universities, other research institutions, and industry. During the first two years of the INCITE program, 10 percent of the resources at NERSC were allocated to INCITE awardees. However, demand for supercomputing resources

Measurement of Bone: Diagnosis of SCI-Induced Osteoporosis and Fracture Risk Prediction.
Troy, Karen L; Morse, Leslie R
2015-01-01
Spinal cord injury (SCI) is associated with a rapid loss of bone mass, resulting in severe osteoporosis and a 5- to 23-fold increase in fracture risk. Despite the seriousness of fractures in SCI, there are multiple barriers to osteoporosis diagnosis and wide variations in treatment practices for SCI-induced osteoporosis. We review the biological and structural changes that are known to occur in bone after SCI in the context of promoting future research to prevent or reduce risk of fracture in this population. We also review the most commonly used methods for assessing bone after SCI and discuss the strengths, limitations, and clinical applications of each method. Although dual-energy x-ray absorptiometry assessments of bone mineral density may be used clinically to detect changes in bone after SCI, 3-dimensional methods such as quantitative CT analysis are recommended for research applications and are explained in detail.

Circulating sclerostin is elevated in short-term and reduced in long-term SCI.
Battaglino, Ricardo A; Sudhakar, Supreetha; Lazzari, Antonio A; Garshick, Eric; Zafonte, Ross; Morse, Leslie R
2012-09-01
Spinal cord injury (SCI) causes profound bone loss due to muscle paralysis resulting in the inability to walk. Sclerostin, a Wnt signaling pathway antagonist produced by osteocytes, is a potent inhibitor of bone formation. Short-term studies in rodent models have demonstrated increased sclerostin in response to mechanical unloading that is reversed with reloading. Although sclerostin inhibition has been proposed as a potential therapy for bone loss, it is not known if sclerostin levels vary with duration of SCI in humans. We analyzed circulating sclerostin in 155 men with varying degrees of SCI who were 1 year or more post-injury. We report that sclerostin levels are greatest in subjects with short-term SCI (≤5 years post-injury) and decrease significantly over the first 5 years post-injury. There was no association between sclerostin and injury duration in subjects with long-term SCI (>5 years post-injury). In subjects with long-term SCI, sclerostin levels were positively associated with lower extremity bone density and bone mineral content. These data suggest that sclerostin levels are initially increased after SCI in response to mechanical unloading. This response is time-limited and as bone loss progresses, circulating sclerostin is lowest in subjects with severe osteoporosis. These findings support a dual role for sclerostin after SCI: a therapeutic target in acute SCI, and a biomarker of osteoporosis severity in chronic SCI. Copyright © 2012 Elsevier Inc.

Full Text Available Resumo Pesquisas sugerem que motivação e envolvimento acadêmico sejam variáveis importantes para o contexto educacional. Assim, a presente pesquisa teve por objetivo principal investigar a relação entre estes construtos. A amostra foi composta por 406 estudantes universitários, a maioria (81,3% com idades variando entre 20 e 30 anos, do sexo feminino (55,2% e de instituições de ensino superior pública (70,4%. Estes responderam a Escala de Motivação Acadêmica (EMA, a Escala de Envolvimento Acadêmico (EEA e a questões sociodemográficas. Os resultados apontaram correlação positiva e significativa entre motivação e envolvimento acadêmico. Foram encontradas ainda diferenças em relação ao sexo, ao período e área do curso e ao envolvimento com atividades extracurriculares. Tais resultados foram discutidos à luz das teorias do envolvimento acadêmico e da autodeterminação. Sugere-se a realização de novas pesquisas a fim de melhor compreender as variáveis que influenciam na motivação e no envolvimento acadêmico de estudantes universitários.

Violência: conceito e vivência entre acadêmicos da área da saúde
Directory of Open Access Journals (Sweden)
Rosiléia Rosa
Full Text Available Trata-se de uma investigação sobre conceitos e vivências sobre violência de acadêmicos do último ano dos cursos de graduação em Enfermagem, Medicina e Odontologia da Universidade Federal de Santa Catarina. Caracterizada como uma pesquisa descritiva exploratória com abordagem qualiquantitativa com 175 acadêmicos, a proposta foi compreender qual a definição de violência para os acadêmicos, quais suas vivências sobre o tema e qual a inserção que o tema violência teve durante a formação acadêmica. As definições sobre violência estiveram fortemente relacionadas a uma visão técnica e priorizaram os danos físicos sofridos pelas pessoas agredidas. Diante de uma situação de violência os acadêmicos reproduziram sentimentos de medo, impotência, raiva e indignação e não reagiram ao presenciar tais atos; evidenciaram que o profissional de saúde não identifica situações de violência quando presta assistência de forma superficial às vítimas; e que a formação acadêmica não discute o tema suficientemente.

Context/Objective The Spinal Cord Injury – Quality of Life (SCI-QOL) measurement system was developed to address the shortage of relevant and psychometrically sound patient reported outcome (PRO) measures available for clinical care and research in spinal cord injury (SCI) rehabilitation. Using a computer adaptive testing (CAT) approach, the SCI-QOL builds on the Patient Reported Outcomes Measurement Information System (PROMIS) and the Quality of Life in Neurological Disorders (Neuro-QOL) initiative. This initial manuscript introduces the background and development of the SCI-QOL measurement system. Greater detail is presented in the additional manuscripts of this special issue. Design Classical and contemporary test development methodologies were employed. Qualitative input was obtained from individuals with SCI and clinicians through interviews, focus groups, and cognitive debriefing. Item pools were field tested in a multi-site sample (n = 877) and calibrated using item response theory methods. Initial reliability and validity testing was performed in a new sample of individuals with traumatic SCI (n = 245). Setting Five Model SCI System centers and one Department of Veterans Affairs Medical Center across the United States. Participants Adults with traumatic SCI. Interventions n/a Outcome Measures n/a Results The SCI-QOL consists of 19 item banks, including the SCI-Functional Index banks, and 3 fixed-length scales measuring physical, emotional, and social aspects of health-related QOL (HRQOL). Conclusion The SCI-QOL measurement system consists of psychometrically sound measures for individuals with SCI. The manuscripts in this special issue provide evidence of the reliability and initial validity of this measurement system. The SCI-QOL also links to other measures designed for a general medical population. PMID:26010962

Can FES-rowing mediate bone mineral density in SCI: a pilot study.
Gibbons, R S; McCarthy, I D; Gall, A; Stock, C G; Shippen, J; Andrews, B J
2014-11-01
A single case study. To compare proximal tibia trabecular bone mineral density (BMD) of a participant with complete spinal cord injury (SCI), long-termed functional electrical stimulation-rowing (FES-R) trained, with previously reported SCI and non-SCI group norms. To estimate lower limb joint contact forces (JCFs) in the FES-R trained participant. UK University and orthopaedic hospital research centre. Bilateral proximal tibial trabecular BMD of the FES-R trained participant was measured using peripheral quantitative computerised tomography, and the data were compared with SCI and non-SCI groups. An instrumented four-channel FES-R system was used to measure the lower limb JCFs in the FES-R trained participant. Structurally, proximal tibial trabecular BMD was higher in the FES-R trained participant compared with the SCI group, but was less than the non-SCI group. Furthermore, left (184.7 mg cm(-3)) and right (160.7 mg cm(-3)) BMD were well above the threshold associated with non-traumatic fracture. The knee JCFs were above the threshold known to mediate BMD in SCI, but below threshold at the hip and ankle. As pathological fractures predominate in the distal femur and proximal tibia in chronic SCI patients, the fact that the FES-R trained participant's knee JCFs were above those known to partially prevent bone loss, suggests that FES-R training may provide therapeutic benefit. Although the elevated bilateral proximal tibial BMD of the FES-R participant provides circumstantial evidence of osteogenesis, this single case precludes any statement on the clinical significance. Further investigations are required involving larger numbers and additional channels of FES to increase loading at the hip and ankle.

Metodología: Se caracterizó la población en búsqueda de factores que se analizaron posteriormente para determinar asociación y predicción, a través de un modelo de regresión logística, del rendimiento académico final. Resultados: Se analizaron 80 estudiantes de edades comprendidas entre 17 y 18, la mayoría mujeres, procedentes de Bogotá, de colegios mixtos, privados y monolingües. El grupo fue homogéneo por factores sociodemográficos, culturales, escolaridad y de motivaciones. Se detectaron rasgos de violencia intrafamiliar, de consumo de alcohol y cigarrillo pero no de drogas psicoactivas. Los resultados obtenidos en la prueba de aptitudes diferenciales y generales (BADyGs del aprendizaje fueron bajos. El análisis mostró que el no leer como pasatiempo, la presencia de violencia intrafamiliar, el haber fumado marihuana, el provenir de un colegio mixto, el no haber realizado estudios profesionales, de quien se depende económicamente, las notas de biología, bioquímica y del promedio trimestral fueron los factores que se asocian con fracaso académico o pérdida de cupo. La variable que predice fracaso académico cuando se controla por los otros factores incluidos en el modelo es el promedio trimestral y la que determina pérdida de cupo es la nota del laboratorio de bioquímica. Conclusiones: Aunque existen factores previos al ingreso que puedan explicar el desempeño académico, es importante evaluar el rendimiento durante el semestre para intervenir rápidamente y evitar el fracaso.

Full Text Available En este estudio se analiza la relación entre la resiliencia, el optimismo disposicional y las dimensiones que constituyen el burnout académico (agotamiento emocional, cinismo y baja eficacia. Para ello, se evaluó a una muestra formada por 463 estudiantes de la Universidad de León. Se emplearon los siguientes instrumentos: Maslach Burnout Inventory-Student Survey (MBI-SS, 10-item Connor-Davidson Resilience Scale (10-item CD-RISC y Life Orientation Test Revised (LOT-R. Los resultados revelan que el burnout académico se relaciona significativamente con la resiliencia y el optimismo. Concretamente, la resiliencia se relaciona positivamente con la eficacia mientras que el optimismo se relaciona positivamente con la eficacia pero negativamente con el agotamiento. Además, la resiliencia predice la eficacia mientras que el optimismo predice el agotamiento. Sin embargo, el cinismo no se relaciona ni con la resiliencia ni con el optimismo. Por último, se contemplan las implicaciones de los resultados obtenidos para el diseño de programas de prevención del burnout académico en estudiantes universitarios.

Charged-Current Neutral Pion production at SciBooNE
International Nuclear Information System (INIS)
Catala-Perez, J.
2009-01-01
SciBooNE, located in the Booster Neutrino Beam at Fermilab, collected data from June 2007 to August 2008 to accurately measure muon neutrino and anti-neutrino cross sections on carbon below 1 GeV neutrino energy. SciBooNE is studying charged current interactions. Among them, neutral pion production interactions will be the focus of this poster. The experimental signature of neutrino-induced neutral pion production is constituted by two electromagnetic cascades initiated by the conversion of the π 0 decay photons, with an additional muon in the final state for CC processes. In this poster, I will present how we reconstruct and select charged-current muon neutrino interactions producing π 0 's in SciBooNE.

Porphyry of Russian Empires in Paris
Bulakh, Andrey
2014-05-01
Porphyry of Russian Empires in Paris A. G. Bulakh (St Petersburg State University, Russia) So called "Schokhan porphyry" from Lake Onega, Russia, belongs surely to stones of World cultural heritage. One can see this "porphyry" at facades of a lovely palace of Pavel I and in pedestal of the monument after Nicolas I in St Petersburg. There are many other cases of using this stone in Russia. In Paris, sarcophagus of Napoleon I Bonaparte is constructed of blocks of this stone. Really, it is Proterozoic quartzite. Geology situation, petrography and mineralogical characteristic will be reported too. Comparison with antique porphyre from the Egyptian Province of the Roma Empire is given.

[History of the Journées Dermatologiques de Paris].
Tilles, G
2013-12-01
Founded in 1801 at the Hôpital Saint-Louis, Paris, under Jean-Louis Alibert, the French School of Dermatology was initially structured around the French Society of Dermatology (1889) and the organization of two world congresses (Paris 1889, 1900). After World War I, the creation of dermatological societies in the provinces infused French dermatology with new energy. In 1922, the first congress of the French-speaking dermatologists further contributed to the public profile of dermatologists in France. The "Journées de Mars" were initiated in 1961 at the Hôpital Saint-Louis, and in 1975 they went on to become the "Journées dermatologiques de Paris". Pr. Jean Civatte played a key role in their creation and in their organization for 30 years. After 1979, since actual patients could no longer be presented, the organizers of the congress had to change the content of the meeting from clinical presentations to post-graduate teaching and clinical research. From its origins in the form of meetings of French dermatologists in an intimate setting at the Hôpital Saint-Louis, the "Journées dermatologiques de Paris" grew within the ensuing decades into a major scientific event of the French-speaking dermatological community, bringing together more than 4000 participants in December each year.

Results of the PERI survey of SciDAC applications
International Nuclear Information System (INIS)
Supinski, Bronis R de; Hollingworth, Jeffrey K; Moore, Shirley; Worley, Patrick H
2007-01-01
The Performance Engineering Research Institute (PERI) project focuses on achieving superior performance for Scientific Discovery through Advanced Computing (SciDAC) applications on leadership class machines through cutting-edge research in performance modeling and automated performance tuning. This focus requires coordinated activities to engage SciDAC application teams. The initial application engagement activity was a survey of these teams to determine their performance goals, the criticality of those goals, current performance of their applications, application characteristics relevant to performance and their plans for future optimization. Using a web-based questionnaire, PERI researchers have worked with application developers to provide this information for over twenty-five applications. This paper describes the initial analysis of the application characteristics and performance goals, as well as current and future application engagement activities driven by these results. While the survey was conducted primarily to meet PERI needs, the results represent a snapshot of the state of SciDAC code development and may be of use to the DOE community at large. Overall, the results show that SciDAC application teams are engaged in significant new code development, which will require flexible performance optimization techniques that can improve performance as the applications evolve

Sci-Hub: What Librarians Should Know and Do about Article Piracy.
Hoy, Matthew B
2017-01-01
The high cost of journal articles has driven many researchers to turn to a new way of getting access: "pirate" article sites. Sci-Hub, the largest and best known of these sites, currently offers instant access to more than 58 million journal articles. Users attracted by the ease of use and breadth of the collection may not realize that these articles are often obtained using stolen credentials and downloading them may be illegal. This article will briefly describe Sci-Hub and how it works, the legal and ethical issues it raises, and the problems it may cause for librarians. Librarians should be aware of Sci-Hub and the ways it may change their patrons' expectations. They should also understand the risks Sci-Hub can pose to their patrons and their institutions.

Holy sci-fi! where science fiction and religion intersect
Nahin, Paul J
2014-01-01
Can a computer have a soul? Are religion and science mutually exclusive? Is there really such a thing as free will? If you could time travel to visit Jesus, would you (and should you)? For hundreds of years, philosophers, scientists, and science fiction writers have pondered these questions and many more. In Holy Sci-Fi!, popular writer Paul Nahin explores the fertile and sometimes uneasy relationship between science fiction and religion. With a scope spanning the history of religion, philosophy, and literature, Nahin follows religious themes in science fiction from Feynman to Foucault, and from Asimov to Aristotle. An intriguing journey through popular and well-loved books and stories, Holy Sci-Fi! shows how sci-fi has informed humanity's attitudes towards our faiths, our future, and ourselves.

The Biosphere Under Potential Paris Outcomes
Ostberg, Sebastian; Boysen, Lena R.; Schaphoff, Sibyll; Lucht, Wolfgang; Gerten, Dieter
2018-01-01
Rapid economic and population growth over the last centuries have started to push the Earth out of its Holocene state into the Anthropocene. In this new era, ecosystems across the globe face mounting dual pressure from human land use change (LUC) and climate change (CC). With the Paris Agreement, the international community has committed to holding global warming below 2°C above preindustrial levels, yet current pledges by countries to reduce greenhouse gas emissions appear insufficient to achieve that goal. At the same time, the sustainable development goals strive to reduce inequalities between countries and provide sufficient food, feed, and clean energy to a growing world population likely to reach more than 9 billion by 2050. Here, we present a macro-scale analysis of the projected impacts of both CC and LUC on the terrestrial biosphere over the 21st century using the Representative Concentration Pathways (RCPs) to illustrate possible trajectories following the Paris Agreement. We find that CC may cause major impacts in landscapes covering between 16% and 65% of the global ice-free land surface by the end of the century, depending on the success or failure of achieving the Paris goal. Accounting for LUC impacts in addition, this number increases to 38%-80%. Thus, CC will likely replace LUC as the major driver of ecosystem change unless global warming can be limited to well below 2°C. We also find a substantial risk that impacts of agricultural expansion may offset some of the benefits of ambitious climate protection for ecosystems.

Housing and the construction of the city: the Paris Habitat Experience
Directory of Open Access Journals (Sweden)
Javier Arpa
2015-12-01
Full Text Available In Paris, the history and the evolution of social housing provision merge with those of a centennial institution. Created in 1914, the Office Public d’Habitations à Bon Marché, currently called Paris Habitat, manages more than 1,200 operations, 120,000 housing units inhabited by 200,000 residents. This article reviews an investigation to this exceptional heritage commissioned by the Pavillon de l'Arsenal in Paris, which resulted in the exhibition and catalogue Paris Habitat: Cent ans de ville, cent ans de vie, presented by the institution in 2015.The investigation, exhibition and publication were organized around the analysis of ten fragments of reality that, rather than matching administrative divisions or urban planning projects, span municipalities, districts and infrastructures. From low-cost to large-scale housing, from concerns with hygiene to ecology issues, each one of the building ensembles analyzed bears witness to the will to change society through housing. Written by the project’s main curator and catalogue editor, this review details the process through which essential questions formulated early on – What is the city we want like? How is it built? – were answered to: selecting from the wealth of material produced by Paris Habitat over one hundred years of activity, the team exposed their political stance on urban strategies at large. Importantly, Paris Habitat’s ‘actions’ substantiated the team’s belief that our knowledge of this long, continuous urban experiment can contribute to improve the metropolises of today and strengthen its ability to answer contemporary concerns: the transformation of offices into housing, new residents’ participation formulas, new building and conception processes, which are key elements in the making of cities that need to be dense, diverse, intense, fertile and agile.

Full Text Available The architecture offices Atelier de la Seine and Rethink have been commissioned with the engineers Pouget Consultants by the social landlord Paris Habitat for the extensive renovation of a social housing estate in the historic centre of Paris. The estate has been built in 1930 and integrates a part of the former college of the Lombard build in the 17th century. It belongs to the social housing typology 'Habitations à Bon Marché (HBM' constructed between1894 and 1949. This typology is generally characterized by its integration in its urban context and an apparent brick facade. The renovation project includes a focus on the reduction of the energy consumption. An important subject, as of the total number of 4.6 millions of social housing in France more than 50 % have been build before 1975 (before the first thermal regulation and many are still considered energy-intensive.

Web technology is a tool that is gaining in popularity. Properly used, it is a powerful tool that has tremendous potential for providing better communication. It can also be effective as a training tool, an information-sharing tool, and as a means of simplifying work load, and facilitating compliance with Company procedures. The issue is one of communication. The challenge facing many large or geographically-distributed companies is how to communicate information to their staff and to their customers. Procedures overseeing quality-assurance programs and commitment to ensuring the quality of products need to be communicated to customers. Equally important is customer feedback. This information from users becomes the kernel for future product development. The issue is even more important when speaking of scientific analysis computer programs (SciCodes). Regular ongoing communication between Primary Holders and End Users is essential in the development and use of SciCodes. Without this communication, quality assurance is at risk. Quality assurance processes are an integral part in developing any SciCode. End Users also have a role to play. Primary Holders keep End Users informed of improvements or new releases. End Users must ensure they act on this information. Equally important, End Users must communicate problems or suggestions to the Primary Holder to remedy or incorporate in new releases. In other words, quality assurance processes become most effective when both Primary Holder and End Users are involved. This requires communication. Web technology offers AECL a means of providing regular, ongoing communication between its scientific-code (SciCode) Primary Holders-Owner Branches and the End Users of these codes within and outside the Company.

To develop a web-based educational resource for health professionals responsible for the management of spinal cord injury (SCI). The resource:www.elearnSCI.org is comprised of seven learning modules, each subdivided into various submodules. Six of the seven modules address the educational needs of all disciplines involved in comprehensive SCI management. The seventh module addresses prevention of SCI. Each submodule includes an overview, activities, self-assessment questions and references. Three hundred and thirty-two experts from The International Spinal Cord Society (ISCoS) and various affiliated societies from 36 countries were involved in developing the resource through 28 subcommittees. The content of each submodule was reviewed and approved by the Education and Scientific Committees of ISCoS and finally by an Editorial Committee of 23 experts. The content of the learning modules is relevant to students and to new as well as experienced SCI healthcare professionals. The content is applicable globally, has received consumer input and is available at no cost. The material is presented on a website underpinned by a sophisticated content-management system, which allows easy maintenance and ready update of all the content. The resource conforms to key principles of e-learning, including appropriateness of curriculum, engagement of learners, innovative approaches, effective learning, ease of use, inclusion, assessment, coherence, consistency, transparency, cost effectiveness and feedback. www.elearnSCI.org provides a cost effective way of training healthcare professionals that goes beyond the textbook and traditional face-to-face teaching.

Paris: Beyond the Climate Dead End through Pledge and Review?
Directory of Open Access Journals (Sweden)
Robert O. Keohane
2016-09-01
Full Text Available The Paris Climate Agreement of December 2015 marks a decisive break from the unsuccessful Kyoto regime. Instead of targets and timetables, it established a Pledge and Review system, under which states will offer Nationally Determined Contributions (INDCs to reducing emissions that cause climate change. But this successful negotiation outcome was achieved at the price of vagueness of obligations and substantial discretion for governments. Many governments will be tempted to use the vagueness of the Paris Agreement, and the discretion that it permits, to limit the scope or intensity of their proposed actions. Whether Pledge and Review under the Paris Agreement will lead to effective action against climate change will therefore depend on the inclination both of OECD countries and newly industrializing countries to take costly actions, which for the OECD countries will include financial transfers to their poorer partners. Domestic politics will be crucial in determining the attitudes of both sets of countries to pay such costs. The actual impact of the Paris Agreement will depend on whether it can be used by domestic groups favoring climate action as a point of leverage in domestic politics—that is, in a “two-level game” simultaneously involving both international and domestic politics.

The Paris classification is an international classification system for describing polyp morphology. Thus far, the validity and reproducibility of this classification have not been assessed. We aimed to determine the interobserver agreement for the Paris classification among seven Western expert endoscopists. A total of 85 short endoscopic video clips depicting polyps were created and assessed by seven expert endoscopists according to the Paris classification. After a digital training module, the same 85 polyps were assessed again. We calculated the interobserver agreement with a Fleiss kappa and as the proportion of pairwise agreement. The interobserver agreement of the Paris classification among seven experts was moderate with a Fleiss kappa of 0.42 and a mean pairwise agreement of 67%. The proportion of lesions assessed as "flat" by the experts ranged between 13 and 40% (Pagreement did not change (kappa 0.38, pairwise agreement 60%). Our study is the first to validate the Paris classification for polyp morphology. We demonstrated only a moderate interobserver agreement among international Western experts for this classification system. Our data suggest that, in its current version, the use of this classification system in daily practice is questionable and it is unsuitable for comparative endoscopic research. We therefore suggest introduction of a simplification of the classification system.

Paris is a commonly used traditional Chinese medicine (TCM), and has antitumor, antibacterial, sedative, analgesic and hemostatic effects. It has been used as an ingredient of 81 Chinese patent medicines, with a wide application and large market demand. Based on the data retrieved from state Intellectual Property Office patent database, a comprehensive analysis was made on Paris patents, so as to explore the current features of Paris patents in the aspects of domestic patent output, development trend, technology field distribution, time dimension, technology growth rate and patent applicant, and reveal the development trend of China's Paris industry. In addition, based on the current Paris resource application and development, a sustainable, multi-channel and multi-level industrial development approach was built. According to the results, studies of Paris in China are at the rapid development period, with a good development trend. However, because wild Paris resources tend to be exhausted, the studies for artificial cultivation technology should be strengthened to promote the industrial development.

Full Text Available The members of the Academic Community have slowly placed themselves in the local and national scene. They work towards a universal educational goal. This requires the renewal of systems and strategies to create knowledge adaptable to the dynamic changes of a globalized world. The quality of higher education depends on many factors, one of the most important, is the professor; as such, the Academic Community takes seriously the professor’s tenure track as well as the overall education. This education implies a deep conceptual understanding of taught academic disciplines, this ideally is demonstrated by the completion of a PhD degree. This is why the University of Guanajuato has placed emphasis on the conformation of Academic Communities. Furthermore, permanent support to the faculty is offered to study graduate degrees with the idea of creating and applying new knowledge and offering them the installations that wil allow them to fulfill their academic functions. The perseverance of the work of the Academic Communities has contributed to their consolidaton in such a way that in 2002 there were only five Academic Communities and now a day there are 14.Los Cuerpos académicos han transitado paulatinamente hacia su posicionamiento en el ámbito estatal y nacional.

The SCI Exercise Self-Efficacy Scale (ESES: development and psychometric properties
Directory of Open Access Journals (Sweden)
Ho Pei-Shu
2007-08-01
Full Text Available Abstract Background Rising prevalence of secondary conditions among persons with spinal cord injury (SCI has focused recent attention to potential health promotion programs designed to reduce such adverse health conditions. A healthy lifestyle for people with SCI, including and specifically, the adoption of a vigorous exercise routine, has been shown to produce an array of health benefits, prompting many providers to recommend the implementation of such activity to those with SCI. Successfully adopting such an exercise regimen however, requires confidence in one's ability to engage in exercise or exercise self-efficacy. Exercise self-efficacy has not been assessed adequately for people with SCI due to a lack of validated and reliable scales, despite self efficacy's status as one of the most widely researched concepts and despite its broad application in health promotion studies. Exercise self efficacy supporting interventions for people with SCI are only meaningful if appropriate measurement tools exist. The objective of our study was to develop a psychometrically sound exercise self-efficacy self-report measure for people with SCI. Methods Based on literature reviews, expert comments and cognitive testing, 10 items were included and made up the 4-point Likert SCI Exercise Self-Efficacy Scale (ESES in its current form. The ESES was administered as part of the first wave of a nationwide survey (n = 368 on exercise behavior and was also tested separately for validity in four groups of individuals with SCI. Reliability and validity testing was performed using SPSS 12.0. Results Cronbach's alpha was .9269 for the ESES. High internal consistency was confirmed in split-half (EQ Length Spearman Brown = .8836. Construct validity was determined using principal component factor analysis by correlating the aggregated ESES items with the Generalised Self Efficacy Scale (GSE.

A process evaluation of a clinical trial. To describe the roles fulfilled by peer health coaches (PHCs) with spinal cord injury (SCI) during a randomized controlled trial research study called 'My Care My Call', a novel telephone-based, peer-led self-management intervention for adults with chronic SCI 1+ years after injury. Connecticut and Greater Boston Area, MA, USA. Directed content analysis was used to qualitatively examine information from 504 tele-coaching calls, conducted with 42 participants with SCI, by two trained SCI PHCs. Self-management was the focus of each 6-month PHC-peer relationship. PHCs documented how and when they used the communication tools (CTs) and information delivery strategies (IDSs) they developed for the intervention. Interaction data were coded and analyzed to determine PHC roles in relation to CT and IDS utilization and application. PHCs performed three principal roles: Role Model, Supporter, and Advisor. Role Model interactions included CTs and IDSs that allowed PHCs to share personal experiences of managing and living with an SCI, including sharing their opinions and advice when appropriate. As Supporters, PHCs used CTs and IDSs to build credible relationships based on dependability and reassuring encouragement. PHCs fulfilled the unique role of Advisor using CTs and IDSs to teach and strategize with peers about SCI self-management. The SCI PHC performs a powerful, flexible role in promoting SCI self-management among peers. Analysis of PHC roles can inform the design of peer-led interventions and highlights the importance for the provision of peer mentor training.

1982-01-01
From 26-31 July, the international particle physics community met for its traditional biennial 'Rochester' jamboree, held this time in Paris. While there were no major physics surprises, there was still plenty of interest for all and the ground that was covered amply demonstrated the progress which has been made since the previous round of international meetings. The emphasis is very much on improving the already considerable level of agreement between different experiments and between experimental results and theoretical predictions

Selective decay by Casimir dissipation in inviscid fluids
International Nuclear Information System (INIS)
Gay-Balmaz, François; Holm, Darryl D
2013-01-01
The problem of parameterizing the interactions of larger scales and smaller scales in fluid flows is addressed by considering a property of two-dimensional (2D) incompressible turbulence. The property we consider is selective decay, in which a Casimir of the ideal formulation (enstrophy in 2D flows, helicity in three-dimensional flows) decays in time, while the energy stays essentially constant. This paper introduces a mechanism that produces selective decay by enforcing Casimir dissipation in fluid dynamics. This mechanism turns out to be related in certain cases to the numerical method of anticipated vorticity discussed in Sadourny and Basdevant (1981 C. R. Acad. Sci. Paris 292 1061–4, 1985 J. Atm. Sci. 42 1353–63). Several examples are given and a general theory of selective decay is developed that uses the Lie–Poisson structure of the ideal theory. A scale-selection operator allows the resulting modifications of the fluid motion equations to be interpreted in several examples as parametrizing the nonlinear, dynamical interactions between disparate scales. The type of modified fluid equation systems derived here may be useful in modelling turbulent geophysical flows where it is computationally prohibitive to rely on the slower, indirect effects of a realistic viscosity, such as in large-scale, coherent, oceanic flows interacting with much smaller eddies.

Welcome to San Diego and the 2009 SciDAC conference. Over the next four days, I would like to present an assessment of the SciDAC program. We will look at where we've been, how we got to where we are and where we are going in the future. Our vision is to be first in computational science, to be best in class in modeling and simulation. When Ray Orbach asked me what I would do, in my job interview for the SciDAC Director position, I said we would achieve that vision. And with our collective dedicated efforts, we have managed to achieve this vision. In the last year, we have now the most powerful supercomputer for open science, Jaguar, the Cray XT system at the Oak Ridge Leadership Computing Facility (OLCF). We also have NERSC, probably the best-in-the-world program for productivity in science that the Office of Science so depends on. And the Argonne Leadership Computing Facility offers architectural diversity with its IBM Blue Gene/P system as a counterbalance to Oak Ridge. There is also ESnet, which is often understated—the 40 gigabit per second dual backbone ring that connects all the labs and many DOE sites. In the President's Recovery Act funding, there is exciting news that ESnet is going to build out to a 100 gigabit per second network using new optical technologies. This is very exciting news for simulations and large-scale scientific facilities. But as one noted SciDAC luminary said, it's not all about the computers—it's also about the science—and we are also achieving our vision in this area. Together with having the fastest supercomputer for science, at the SC08 conference, SciDAC researchers won two ACM Gordon Bell Prizes for the outstanding performance of their applications. The DCA++ code, which solves some very interesting problems in materials, achieved a sustained performance of 1.3 petaflops, an astounding result and a mark I suspect will last for some time. The LS3DF application for studying nanomaterials also required the development of a

Understanding the factors that can predict greater quality of life (QoL) is important for adults with spinal cord injury (SCI), given that they report lower levels of QoL than the general population. To build a conceptual model linking SCI-related needs, secondary complications, and QoL in adults with SCI. Prior to testing the conceptual model, we aimed to develop and evaluate the factor structure for both SCI-related needs and secondary complications. Individuals with a traumatic SCI (N = 1,137) responded to an online survey measuring 13 SCI-related needs, 13 secondary complications, and the Life Satisfaction Questionnaire to assess QoL. The SCI-related needs and secondary complications were conceptualized into factors, tested with a confirmatory factor analysis, and subsequently evaluated in a structural equation model to predict QoL. The confirmatory factor analysis supported a 2-factor model for SCI related needs, χ(2)(61, N = 1,137) = 250.40, P SCI-related needs (β = -.22 and -.20, P SCI-related needs of individuals with SCI and preventing or managing secondary complications are essential to their QoL.

2015-11-01
The objective of this study was to compare outcomes and patterns of engaging with a telehealth intervention (CareCall) by adult wheelchair users with severe mobility limitations with a diagnosis of multiple sclerosis (MS) or spinal cord injury (SCI). The design of this study is a secondary analysis from a pilot randomized controlled trial with 106 participants with SCI and 36 participants with MS. General linear model results showed that an interaction between baseline depression score and study group significantly predicted reduced depression at 6 mos for subjects with both diagnoses (P = 0.01). For those with MS, CareCall increased participants' physical independence (P SCI (P = 0.005). Those with SCI missed more calls (P SCI, and in increasing health care access and physical independence for those with a diagnosis of MS. Future research should aim to enhance the efficacy of such an intervention for participants with SCI.

To describe the development and psychometric properties of the Spinal Cord Injury--Quality of Life (SCI-QOL) Bladder Management Difficulties and Bowel Management Difficulties item banks and Bladder Complications scale. Using a mixed-methods design, a pool of items assessing bladder and bowel-related concerns were developed using focus groups with individuals with spinal cord injury (SCI) and SCI clinicians, cognitive interviews, and item response theory (IRT) analytic approaches, including tests of model fit and differential item functioning. Thirty-eight bladder items and 52 bowel items were tested at the University of Michigan, Kessler Foundation Research Center, the Rehabilitation Institute of Chicago, the University of Washington, Craig Hospital, and the James J. Peters VA Medical Center, Bronx, NY. Seven hundred fifty-seven adults with traumatic SCI. The final item banks demonstrated unidimensionality (Bladder Management Difficulties CFI=0.965; RMSEA=0.093; Bowel Management Difficulties CFI=0.955; RMSEA=0.078) and acceptable fit to a graded response IRT model. The final calibrated Bladder Management Difficulties bank includes 15 items, and the final Bowel Management Difficulties item bank consists of 26 items. Additionally, 5 items related to urinary tract infections (UTI) did not fit with the larger Bladder Management Difficulties item bank but performed relatively well independently (CFI=0.992, RMSEA=0.050) and were thus retained as a separate scale. The SCI-QOL Bladder Management Difficulties and Bowel Management Difficulties item banks are psychometrically robust and are available as computer adaptive tests or short forms. The SCI-QOL Bladder Complications scale is a brief, fixed-length outcomes instrument for individuals with a UTI.

SciSpark's SRDD : A Scientific Resilient Distributed Dataset for Multidimensional Data
Palamuttam, R. S.; Wilson, B. D.; Mogrovejo, R. M.; Whitehall, K. D.; Mattmann, C. A.; McGibbney, L. J.; Ramirez, P.
2015-12-01
Remote sensing data and climate model output are multi-dimensional arrays of massive sizes locked away in heterogeneous file formats (HDF5/4, NetCDF 3/4) and metadata models (HDF-EOS, CF) making it difficult to perform multi-stage, iterative science processing since each stage requires writing and reading data to and from disk. We have developed SciSpark, a robust Big Data framework, that extends ApacheTM Spark for scaling scientific computations. Apache Spark improves the map-reduce implementation in ApacheTM Hadoop for parallel computing on a cluster, by emphasizing in-memory computation, "spilling" to disk only as needed, and relying on lazy evaluation. Central to Spark is the Resilient Distributed Dataset (RDD), an in-memory distributed data structure that extends the functional paradigm provided by the Scala programming language. However, RDDs are ideal for tabular or unstructured data, and not for highly dimensional data. The SciSpark project introduces the Scientific Resilient Distributed Dataset (sRDD), a distributed-computing array structure which supports iterative scientific algorithms for multidimensional data. SciSpark processes data stored in NetCDF and HDF files by partitioning them across time or space and distributing the partitions among a cluster of compute nodes. We show usability and extensibility of SciSpark by implementing distributed algorithms for geospatial operations on large collections of multi-dimensional grids. In particular we address the problem of scaling an automated method for finding Mesoscale Convective Complexes. SciSpark provides a tensor interface to support the pluggability of different matrix libraries. We evaluate performance of the various matrix libraries in distributed pipelines, such as Nd4jTM and BreezeTM. We detail the architecture and design of SciSpark, our efforts to integrate climate science algorithms, parallel ingest and partitioning (sharding) of A-Train satellite observations from model grids.

Implication of altered autonomic control for orthostatic tolerance in SCI.
Wecht, Jill Maria; Bauman, William A
2018-01-01
Neural output from the sympathetic and parasympathetic branches of the autonomic nervous system (ANS) are integrated to appropriately control cardiovascular responses during routine activities of daily living including orthostatic positioning. Sympathetic control of the upper extremity vasculature and the heart arises from the thoracic cord between T1 and T5, whereas splanchnic bed and lower extremity vasculature receive sympathetic neural input from the lower cord between segments T5 and L2. Although the vasculature is not directly innervated by the parasympathetic nervous system, the SA node is innervated by post-ganglionic vagal nerve fibers via cranial nerve X. Segmental differences in sympathetic cardiovascular innervation highlight the effect of lesion level on orthostatic cardiovascular control following spinal cord injury (SCI). Due to impaired sympathetic cardiovascular control, many individuals with SCI, particularly those with lesions above T6, are prone to orthostatic hypotension (OH) and orthostatic intolerance (OI). Symptomatic OH, which may result in OI, is a consequence of episodic reductions in cerebral perfusion pressure and the symptoms may include: dizziness, lightheadedness, nausea, blurred vision, ringing in the ears, headache and syncope. However, many, if not most, individuals with SCI who experience persistent and episodic hypotension and OH do not report symptoms of cerebral hypoperfusion and therefore do not raise clinical concern. This review will discuss the mechanism underlying OH and OI following SCI, and will review our knowledge to date regarding the prevalence, consequences and possible treatment options for these conditions in the SCI population.

Smoke Inhalation and Cyanide Poisoning: 20 Years of Paris Experience
International Nuclear Information System (INIS)
Baud, F. J.
2007-01-01
Hydroxocobalamin has been used as a cyanide poisoning antidote for many years in France. It has recently been approved by the US FDA. In Paris, hydroxocobalamin is carried by the Brigade de Sapeurs Pompiers (Paris Fire Brigade) in mobile intensive care vehicles and has been administered empirically to victims of enclosed-space fire smoke inhalation who meet the criteria of having soot in the nose, mouth, or throat, any alteration in mental status or disturbance in consciousness, and especially if any degree of hypotension is present (BP less than or equal to 100 mmHg systolic). The administration of hydroxocobalamin at the scene was shown to be safe. Hydroxocobalamin has also been efficacious and safe in 'pure' cyanide poisoning, as long as brain death has not already occurred. A 'toxidrome' of cyanide poisoning has been developed in our institution in Paris, and its application can assist in making the diagnosis of this life-threatening poisoning which cannot be emergent diagnosed by currently-available laboratory methods.(author)

Full Text Available Este artículo presenta los resultados del estudio cuyo objetivo fue establecer las diferencias en el riesgo familiar entre dos grupos de familias: con niños escolares de alto rendimiento y niños de bajo rendimiento académico en un centro educativo distrital de Bogotá. Metodología: estudio descriptivo comparativo transversal con un componente analítico y abordaje cuantitativo; la muestra fue de 186 familias, durante abril a julio de 2007. Los resultados muestran predominio de familias nucleares en ambos grupos (65%, relación inversa entre el riesgo familiar total evaluado por el instrumento RFT 7-70 y el rendimiento académico del escolar de la familia, es decir que las familias que registraron riesgo alto (9% y medio (31% en mayor proporción son familias con escolares de bajo rendimiento académico, frente al predominio del riesgo familiar bajo (78% en las familias con niños de alto rendimiento. Se aplicó t de student para diferencia de medias y se encontró asociación (P = 0,02 entre el riesgo familiar total alto y el bajo rendimiento académico del escolar. En conclusión, estos resultados sugieren principalmente que se deben priorizar los factores de riesgo que determinan mayor riesgo familiar en familias con escolares de bajo rendimiento académico y dar atención de salud integral con enfoque familiar e intersectorial, y participación activa de la comunidad. Continuar investigando en posibles asociaciones entre salud individual, prácticas de salud, educación, ambiente socioeconómico y psicoafectivo de la familia y el logro educativo de escolares en familias con niños en edad escolar.

The legal character and operational relevance of the Paris Agreement's temperature goal
Rajamani, Lavanya; Werksman, Jacob
2018-05-01
This article assesses the legal character and operational relevance of the Paris Agreement's 1.5°C temperature goal. This article begins with a textual analysis of the 1.5°C goal. It considers whether the goal creates individual or collective obligations for Parties, and whether it is sufficiently specific to enable the tracking of individual or collective performance. Next, it assesses the operational relevance of the 1.5°C temperature goal, by considering the role it will play in the Paris Agreement's institutions and procedures. To the extent that the goal plays a role, and implies global limits on greenhouse gas emissions, this article observes that it could have implications for the sharing of the effort between Parties. Thus, this article considers the relevance of equity and the principle of common but differentiated responsibilities and respective capabilities, in the light of different national circumstances, to understanding how the 1.5°C goal could be reached. In this context, this article explores whether the 1.5°C goal could play a role in the Paris Agreement's `ambition cycle'. Finally, this article asks whether there are any legal or political implications, individually or collectively under the Paris Agreement, should the Parties fail to achieve the 1.5°C goal. This article is part of the theme issue `The Paris Agreement: understanding the physical and social challenges for a warming world of 1.5°C above pre-industrial levels'.

OPENING REMARKS: SciDAC: Scientific Discovery through Advanced Computing
Strayer, Michael
2005-01-01
Good morning. Welcome to SciDAC 2005 and San Francisco. SciDAC is all about computational science and scientific discovery. In a large sense, computational science characterizes SciDAC and its intent is change. It transforms both our approach and our understanding of science. It opens new doors and crosses traditional boundaries while seeking discovery. In terms of twentieth century methodologies, computational science may be said to be transformational. There are a number of examples to this point. First are the sciences that encompass climate modeling. The application of computational science has in essence created the field of climate modeling. This community is now international in scope and has provided precision results that are challenging our understanding of our environment. A second example is that of lattice quantum chromodynamics. Lattice QCD, while adding precision and insight to our fundamental understanding of strong interaction dynamics, has transformed our approach to particle and nuclear science. The individual investigator approach has evolved to teams of scientists from different disciplines working side-by-side towards a common goal. SciDAC is also undergoing a transformation. This meeting is a prime example. Last year it was a small programmatic meeting tracking progress in SciDAC. This year, we have a major computational science meeting with a variety of disciplines and enabling technologies represented. SciDAC 2005 should position itself as a new corner stone for Computational Science and its impact on science. As we look to the immediate future, FY2006 will bring a new cycle to SciDAC. Most of the program elements of SciDAC will be re-competed in FY2006. The re-competition will involve new instruments for computational science, new approaches for collaboration, as well as new disciplines. There will be new opportunities for virtual experiments in carbon sequestration, fusion, and nuclear power and nuclear waste, as well as collaborations

A origem da Universidade de Paris (I
Directory of Open Access Journals (Sweden)
Ruy Afonso da Costa Nunes
1967-03-01
Foi no princípio do século XIII que a Universidade começou a organizar-se . Em 1200, por um privilégio outorgado por Filipe Augusto, a corporação dos professôres e dos estudantes de Paris passou a reger-se pela jurisdição eclesiástica, furtando-se dessa maneira ao fôro civil. Em 1215, Roberto de Courçon, legado pontifício, conce-deu ao studium parisiense seus primeiros estatutos oficiais . Se tais medidas constituíram o início da organização jurídica da Universidade, foram, por outro lado, o remate de um lento processo de formação . Mas, como decorreu êsse movimento germinativo da Universidade de Paris? Que condições o prepararam e que fatôres contri-buíram para sua gênese e desenvolvimento?

Neuropathic pain and SCI: Identification and treatment strategies in the 21st century.
Hatch, Maya N; Cushing, Timothy R; Carlson, Gregory D; Chang, Eric Y
2018-01-15
Pain is a common complication in patients following spinal cord injury (SCI), with studies citing up to 80% of patients reporting some form of pain. Neuropathic pain (NP) makes up a substantial percentage of all pain symptoms in patients with SCI and is often complex. Given the high prevalence of NP in patients with SCI, proper identification and treatment is imperative. Indeed, identification of pain subtypes is a vital step toward determining appropriate treatment. A variety of pharmacological and non-pharmacological treatments can be undertaken including antiepileptics, tricyclic antidepressants, opioids, transcranial direct current stimulation, and invasive surgical procedures. Despite all the available treatment options and advances in the field of SCI medicine, providing adequate treatment of NP after SCI continues to be challenging. It is therefore extremely important for clinicians to have a strong foundation in the identification of SCI NP, as well as an understanding of appropriate treatment options. Here, we highlight the definitions and classification tools available for NP identification, and discuss current treatment options. We hope that this will not only provide a better understanding of NP for physicians in various subspecialties, but that it will also help guide future research on this subject.

2017-01-01
Full Text Available Background: The Paris System for Reporting Urinary Cytology represents a significant improvement in classification of urinary specimens. The system acknowledges the difficulty in cytologically diagnosing low-grade urothelial carcinomas and has developed categories to deal with this issue. The system uses six categories: unsatisfactory, negative for high-grade urothelial carcinoma (NHGUC, atypical urothelial cells, suspicious for high-grade urothelial carcinoma, high-grade urothelial carcinoma, other malignancies and a seventh subcategory (low-grade urothelial neoplasm. Methods: Three hundred and fifty-seven urine specimens were independently reviewed by four cytopathologists unaware of the previous diagnoses. Each cytopathologist rendered a diagnosis according to the Paris System categories. Agreement was assessed using absolute agreement and weighted chance-corrected agreement (kappa. Disagreements were classified as low impact and high impact based on the potential impact of a misclassification on clinical management. Results: The average absolute agreement was 65% with an average expected agreement of 44%. The average chance-corrected agreement (kappa was 0.32. Nine hundred and ninety-nine of 1902 comparisons between rater pairs were in agreement, but 12% of comparisons differed by two or more categories for the category NHGUC. Approximately 15% of the disagreements were classified as high clinical impact. Conclusions: Our findings indicated that the scheme recommended by the Paris System shows adequate precision for the category NHGUC, but the other categories demonstrated unacceptable interobserver variability. This low level of diagnostic precision may negatively impact the applicability of the Paris System for widespread clinical application.

Constructing large scale SCI-based processing systems by switch elements
International Nuclear Information System (INIS)
Wu, B.; Kristiansen, E.; Skaali, B.; Bogaerts, A.; Divia, R.; Mueller, H.
1993-05-01
The goal of this paper is to study some of the design criteria for the switch elements to form the interconnection of large scale SCI-based processing systems. The approved IEEE standard 1596 makes it possible to couple up to 64K nodes together. In order to connect thousands of nodes to construct large scale SCI-based processing systems, one has to interconnect these nodes by switch elements to form different topologies. A summary of the requirements and key points of interconnection networks and switches is presented. Two models of the SCI switch elements are proposed. The authors investigate several examples of systems constructed for 4-switches with simulations and the results are analyzed. Some issues and enhancements are discussed to provide the ideas behind the switch design that can improve performance and reduce latency. 29 refs., 11 figs., 3 tabs

GeoSciML v3.0 - a significant upgrade of the CGI-IUGS geoscience data model
Raymond, O.; Duclaux, G.; Boisvert, E.; Cipolloni, C.; Cox, S.; Laxton, J.; Letourneau, F.; Richard, S.; Ritchie, A.; Sen, M.; Serrano, J.-J.; Simons, B.; Vuollo, J.
2012-04-01
GeoSciML version 3.0 (http://www.geosciml.org), released in late 2011, is the latest version of the CGI-IUGS* Interoperability Working Group geoscience data interchange standard. The new version is a significant upgrade and refactoring of GeoSciML v2 which was released in 2008. GeoSciML v3 has already been adopted by several major international interoperability initiatives, including OneGeology, the EU INSPIRE program, and the US Geoscience Information Network, as their standard data exchange format for geoscience data. GeoSciML v3 makes use of recently upgraded versions of several Open Geospatial Consortium (OGC) and ISO data transfer standards, including GML v3.2, SWE Common v2.0, and Observations and Measurements v2 (ISO 19156). The GeoSciML v3 data model has been refactored from a single large application schema with many packages, into a number of smaller, but related, application schema modules with individual namespaces. This refactoring allows the use and future development of modules of GeoSciML (eg; GeologicUnit, GeologicStructure, GeologicAge, Borehole) in smaller, more manageable units. As a result of this refactoring and the integration with new OGC and ISO standards, GeoSciML v3 is not backwardly compatible with previous GeoSciML versions. The scope of GeoSciML has been extended in version 3.0 to include new models for geomorphological data (a Geomorphology application schema), and for geological specimens, geochronological interpretations, and metadata for geochemical and geochronological analyses (a LaboratoryAnalysis-Specimen application schema). In addition, there is better support for borehole data, and the PhysicalProperties model now supports a wider range of petrophysical measurements. The previously used CGI_Value data type has been superseded in favour of externally governed data types provided by OGC's SWE Common v2 and GML v3.2 data standards. The GeoSciML v3 release includes worked examples of best practice in delivering geochemical

Spinal Cord Injury Community Survey: Understanding the Needs of Canadians with SCI.
Noreau, Luc; Noonan, Vanessa K; Cobb, John; Leblond, Jean; Dumont, Frédéric S
2014-01-01
There is a lack of literature regarding service needs of people with SCI living in the community. Better assessment of expressed and met and unmet needs would help in the development of effective service delivery. From a national SCI Community Survey in Canada, the aim was to identify the most critical service needs of people living in the community at least 1 year post discharge from rehabilitation and the support they received to meet their needs. Data were collected mainly through a secure Web site and encompassed demographics, personal and household income, an SCI severity measure, and an SCI community needs measure containing information on 13 SCI-related needs. A total of 1,549 persons with SCI (traumatic lesion, n = 1,137; nontraumatic lesion, n = 412) across Canada completed the survey. Most critical needs for community integration were expressed by a substantial proportion of survey participants, but significantly more expressed and met needs were reported by persons with a traumatic than a nontraumatic lesion. Personal and environmental characteristics influenced the probability of expressing and meeting needs (eg, severity of injury and household income). Help and support to meet expressed needs were received from government agencies, community organizations, and friends or family. Better assessment of expressed and met or unmet needs for services remains a challenge but will serve as a tool to optimize service delivery in the community. Environmental barriers to services, particularly the process of getting needs met and associated costs, remain an issue that requires a reconsideration of some aspects of access to services.

Full Text Available La lectura y escritura académicas en la universidad escasamente han sido atendidas como materia y contenido de enseñanza por los profesores. Se asume tácitamente que los alumnos han adquirido, durante su formación en los niveles y grados escolares previos, las competencias suficientes para desempeñarse como lectores y escritores especializados en las temáticas del estudio disciplinario. Sin embargo, los escritos de los estudiantes muestran un panorama poco optimista respecto a las competencias que han adquirido y desarrollado. Ante esta necesidad, y a partir de algunas dificultades específicas de escritura identificadas en las versiones de un capítulo de tesis de estudiantes del 8o semestre de la Licenciatura en Educación de Adultos (UPN, se emprendió una intervención didáctica para orientar la escritura académica. Tales fueron los objetivos de investigación e intervención que se atendieron y de los cuales trataremos en el presente artículo. Al final, descubrimos que la escritura académica guiada puede dar lugar a versiones del desempeño académico y sus expresiones disciplinarias cada vez más logradas y exitosas.

GeoSciML version 3: A GML application for geologic information
International Union of Geological Sciences., I. C.; Richard, S. M.
2011-12-01
After 2 years of testing and development, XML schema for GeoSciML version 3 are now ready for application deployment. GeoSciML draws from many geoscience data modelling efforts to establish a common suite of feature types to represent information associated with geologic maps (materials, structures, and geologic units) and observations including structure data, samples, and chemical analyses. After extensive testing and use case analysis, in December 2008 the CGI Interoperability Working Group (IWG) released GeoSciML 2.0 as an application schema for basic geological information. GeoSciML 2.0 is in use to deliver geologic data by the OneGeology Europe portal, the Geological Survey of Canada Groundwater Information Network (wet GIN), and the Auscope Mineral Resources portal. GeoSciML to version 3.0 is updated to OGC Geography Markup Language v3.2, re-engineered patterns for association of element values with controlled vocabulary concepts, incorporation of ISO19156 Observation and Measurement constructs for representing numeric and categorical values and for representing analytical data, incorporation of EarthResourceML to represent mineral occurrences and mines, incorporation of the GeoTime model to represent GSSP and stratigraphic time scale, and refactoring of the GeoSciML namespace to follow emerging ISO practices for decoupling of dependencies between standardized namespaces. These changes will make it easier for data providers to link to standard vocabulary and registry services. The depth and breadth of GeoSciML remains largely unchanged, covering the representation of geologic units, earth materials and geologic structures. ISO19156 elements and patterns are used to represent sampling features such as boreholes and rock samples, as well as geochemical and geochronologic measurements. Geologic structures include shear displacement structures (brittle faults and ductile shears), contacts, folds, foliations, lineations and structures with no preferred

Translation of therapeutic interventions for spinal cord injury (SCI) from laboratory to clinic has been historically challenging, highlighting the need for robust models of injury that more closely mirror the human condition. The high prevalence of acute, naturally occurring SCI in pet dogs provides a unique opportunity to evaluate expeditiously promising interventions in a population of animals that receive diagnoses and treatment clinically in a manner similar to persons with SCI, while adhering to National Institutes of Health guidelines for scientific rigor and transparent reporting. In addition, pet dogs with chronic paralysis are often maintained long-term by their owners, offering a similarly unique population for study of chronic SCI. Despite this, only a small number of studies have used the clinical dog model of SCI. The Canine Spinal Cord Injury Consortium (CANSORT-SCI) was recently established by a group of veterinarians and basic science researchers to promote the value of the canine clinical model of SCI. The CANSORT-SCI group held an inaugural meeting November 20 and 21, 2015 to evaluate opportunities and challenges to the use of pet dogs in SCI research. Key challenges identified included lack of familiarity with the model among nonveterinary scientists and questions about how and where in the translational process the canine clinical model would be most valuable. In light of these, we review the natural history, outcome, and available assessment tools associated with canine clinical SCI with emphasis on their relevance to human SCI and the translational process.

Anon.
1995-01-01
Following the agreement between French and German professionals of automobile and industrial vehicle, the Road Transport world exhibition will take place alternatively in Paris and Hanover. The 1995 meeting has taken place in Paris (September 15-21) and about 20 countries were represented. Road transport is the principal way of goods transportation in France and represent 88% of the traffic explained in tons gross and 70% in tons km. The petroleum dependence of the transportation sector is becoming a worrying problem as the gasoline and diesel fuels taxes will be discussed in the 1996 financial laws project. According to the last ''Worldwide energetic perspectives'' report published by the IEA, in 2010 the transportation sector could absorb more than 60% of the worldwide petroleum consumption. This increase represents a challenge to the petroleum industry to increase the energetic efficiency of the vehicle fuels and the production of diesel fuels, and conversely to reduce the pollution effluents.

SciServer: An Online Collaborative Environment for Big Data in Research and Education
Raddick, Jordan; Souter, Barbara; Lemson, Gerard; Taghizadeh-Popp, Manuchehr
2017-01-01
For the past year, SciServer Compute (http://compute.sciserver.org) has offered access to big data resources running within server-side Docker containers. Compute has allowed thousands of researchers to bring advanced analysis to big datasets like the Sloan Digital Sky Survey and others, while keeping the analysis close to the data for better performance and easier read/write access. SciServer Compute is just one part of the SciServer system being developed at Johns Hopkins University, which provides an easy-to-use collaborative research environment for astronomy and many other sciences.SciServer enables these collaborative research strategies using Jupyter notebooks, in which users can write their own Python and R scripts and execute them on the same server as the data. We have written special-purpose libraries for querying, reading, and writing data. Intermediate results can be stored in large scratch space (hundreds of TBs) and analyzed directly from within Python or R with state-of-the-art visualization and machine learning libraries. Users can store science-ready results in their permanent allocation on SciDrive, a Dropbox-like system for sharing and publishing files.SciServer Compute’s virtual research environment has grown with the addition of task management and access control functions, allowing collaborators to share both data and analysis scripts securely across the world. These features also open up new possibilities for education, allowing instructors to share datasets with students and students to write analysis scripts to share with their instructors. We are leveraging these features into a new system called “SciServer Courseware,” which will allow instructors to share assignments with their students, allowing students to engage with big data in new ways.SciServer has also expanded to include more datasets beyond the Sloan Digital Sky Survey. A part of that growth has been the addition of the SkyQuery component, which allows for simple, fast

Tinnitus is a result of hyper-activity/hyper-synchrony of auditory neurons coding the tinnitus frequency, which has developed to synchronous mass activity owing the lack of inhibition. We assume that removal of exactly these frequency components from an auditory stimulus will cause the brain to reorganize around tonotopic regions coding the tinnitus frequency. Based on this assumption a novel treatment for tonal tinnitus - tailor-made notched music training (TMNMT) (Proc Natl Acad Sci USA 107:1207-1210, 2010; Ann N Y Acad Sci 1252:253-258, 2012; Frontiers Syst Neurosci 6:50, 2012) has been introduced and will be tested in this clinical trial on a large number of tinnitus patients. A randomized controlled trial (RCT) in parallel group design will be performed in a double-blinded manner. The choice of the intervention we are going to apply is based on two "proof of concept" studies in humans (Proc Natl Acad Sci USA 107:1207-1210, 2010; Ann N Y Acad Sci 1252:253-258, 2012; Frontiers Syst Neurosci 6:50, 2012; PloS One 6(9):e24685, 2011) and on a recent animal study (Front Syst Neurosci 7:21, 2013).The RCT includes 100 participants with chronic, tonal tinnitus who listened to tailor-made notched music (TMNM) for two hours a day for three months. The effect of TMNMT is assessed by the tinnitus handicap questionnaire and visual analogue scales (VAS) measuring perceived tinnitus loudness, distress and handicap. This is the first randomized controlled trial applying TMNMT on a larger number of patients with tonal tinnitus. Our data will verify more securely and reliably the effectiveness of this kind of completely non-invasive and low-cost treatment approach on tonal tinnitus. Current Controlled Trials ISRCTN04840953.

3-D basin modelling of the Paris Basin: diagenetic and hydrogeologic implications
International Nuclear Information System (INIS)
Violette, S.; Goncalves, J.; Jost, A.; Marsily, G. de
2004-01-01
A 3-D basin model of the Paris basin is presented in order to simulate through geological times fluid, heat and solute fluxes. This study emphasizes: i) the contribution of basin models to the quantitative hydrodynamic understanding of behaviour of the basin over geological times; ii) the additional use of Atmospheric General Circulation model (AGCM) to provide palaeo-climatic boundaries for a coupled flow and mass transfer modelling, constrained by geochemical and isotopic tracers and; iii) the integration of different types of data (qualitative and quantitative) to better constrain the simulations. Firstly, in a genetic way, basin model is used to reproduce geological, physical and chemical processes occurring in the course of the 248 My evolution of the Paris basin that ought to explain the present-day hydraulic properties at the regional scale. As basin codes try to reproduce some of these phenomena, they should be able to give a plausible idea of the regional-scale permeability distribution of the multi-layered system, of the pre-industrial hydrodynamic conditions within the aquifers and of the diagenesis timing and type of hydrodynamic processes involved. Secondly, climate records archived in the Paris basin groundwater suggest that climate and morphological features have an impact on the hydrogeological processes, particularly during the last 5 My. An Atmospheric General Circulation model is used with a refined spatial resolution centred on the Paris basin to reproduce the climate for the present, the Last Glacial Maximum (21 ky) and the middle Pliocene (3 My). These climates will be prescribed, through forcing functions to the hydrological code with the main objective of understanding the way aquifers and aquitards react under different climate conditions, the period and the duration of these effects. Finally, the Paris basin has been studied for a number of years by different scientific communities, thus a large amount of data has been collected. By

“Real” Places in Marguerite Duras’s Wartime Paris
Directory of Open Access Journals (Sweden)
Jennifer Willging
2011-06-01
Full Text Available In the four autobiographical narratives in Marguerite Duras’s La Douleur (1985 The War (1994, over one hundred proper place names appear. While these place names all refer to real places, the relationship between these signifiers and their actual geographical referents is mediated, first by their signifieds—the reader’s mental constructs of the places mentioned—and further by their appearance in a text that necessarily creates its own, non-material world. Yet this essay argues that in this uncharacteristically realist text Duras works hard to create the illusion that the Paris there is in fact Occupied Paris, the real city in which she lived out the experiences recounted in her text. She does this, in large part, by indicating the location of each scene with meticulous precision, thus grounding the stories, quite literally, in a geographically and historically situated reality. While many of these sites are among the best-known, and literal, lieux de mémoire ‘sites of memory’ of the Paris of the Second World War, the mention of more obscure places might appear gratuitous. Yet it is precisely in their gratuity, that such details become essential elements of the forceful effet de réel ‘reality effect’ created in the text.

Some individuals with spinal cord injury (SCI) remain pressure ulcer (PU) free whilst others experience a recurring cycle of tissue breakdown. Detailed analysis of gluteal muscle characteristics may provide insights to local tissue viability variability. The study hypothesis was that SCI individuals have altered muscle composition compared to able-bodied (AB). Ten AB and ten SCI received a supine pelvic CT scan, with contrast. Cross-sectional area (CSA) and overall muscle volume were derived using image analysis. Gluteal muscle tissue type was classified at the S2/S3 sacral vertebrae midpoint, the superior greater trochanters margin (GT) and the inferior ischial tuberosities margin (IT) using the linear transformation Hounsfield Unit scale. SCI gluteal CSA was less than for AB throughout the muscle, with the greatest relative atrophy at the IT (48%). Average AB gluteal volume was nearly double SCI. Eight SCI had over 20% infiltrative adipose tissue, three with over 50%. SCI gluteal CSA and intramuscular fat infiltration were significantly negatively correlated (p SCI IT axial slices showed less lean muscle and higher intramuscular fat infiltration than more proximally (p SCI gluteal muscle characteristics were indicative of impaired tissue viability. SCI disuse muscle atrophy was anticipated; the analytic approach further indicated that intramuscular atrophy was not uniform. SCI muscle composition showed increased proportions of both low density muscle and adipose tissue. CT scan with contrast is effective for gluteal muscle characterization. This assessment technique may contribute to determination of personalized risk for PU development and other secondary complications. Published by Elsevier Ltd.

GeoSciGraph: An Ontological Framework for EarthCube Semantic Infrastructure
Gupta, A.; Schachne, A.; Condit, C.; Valentine, D.; Richard, S.; Zaslavsky, I.
2015-12-01
The CINERGI (Community Inventory of EarthCube Resources for Geosciences Interoperability) project compiles an inventory of a wide variety of earth science resources including documents, catalogs, vocabularies, data models, data services, process models, information repositories, domain-specific ontologies etc. developed by research groups and data practitioners. We have developed a multidisciplinary semantic framework called GeoSciGraph semantic ingration of earth science resources. An integrated ontology is constructed with Basic Formal Ontology (BFO) as its upper ontology and currently ingests multiple component ontologies including the SWEET ontology, GeoSciML's lithology ontology, Tematres controlled vocabulary server, GeoNames, GCMD vocabularies on equipment, platforms and institutions, software ontology, CUAHSI hydrology vocabulary, the environmental ontology (ENVO) and several more. These ontologies are connected through bridging axioms; GeoSciGraph identifies lexically close terms and creates equivalence class or subclass relationships between them after human verification. GeoSciGraph allows a community to create community-specific customizations of the integrated ontology. GeoSciGraph uses the Neo4J,a graph database that can hold several billion concepts and relationships. GeoSciGraph provides a number of REST services that can be called by other software modules like the CINERGI information augmentation pipeline. 1) Vocabulary services are used to find exact and approximate terms, term categories (community-provided clusters of terms e.g., measurement-related terms or environmental material related terms), synonyms, term definitions and annotations. 2) Lexical services are used for text parsing to find entities, which can then be included into the ontology by a domain expert. 3) Graph services provide the ability to perform traversal centric operations e.g., finding paths and neighborhoods which can be used to perform ontological operations like

Mirroring of fibre ends for the LHCb SciFi project
Joram, Christian
2014-01-01
The relatively low light yields for tracks close to the midplane (y=0) of the SciFi tracker, in particular after radiation damage due to ionizing radiation, suggests to mirror the fibre ends. This note describes a set of tests and measurements in order to establish a viable mirror technology which combines high reflectivity with simplicity and low cost. The following technologies were evaluated: Aluminized Mylar film glued to the fibre ends, 3M Enhanced Specular Reflectance film glued to the fibre ends, Thin Film Aluminium vacuum coated on the fibre ends. The tests show that Aluminized Mylar film is a viable solution fulfilling all SciFi requirements. ESR film leads potentially to a higher reflectivity but its usability when glued to fibre ends could not (yet) be demonstrated. The Thin Film Aluminium coating disqualifies for reasons of cost and complexity without any performance gain. This report is meant as backup document for the LHCb SciFi TDR document to be submitted in February 2014.

USA Withdrawal from Paris Agreement – What Next?
Directory of Open Access Journals (Sweden)
Sergey Chestnoy
2017-12-01
Full Text Available In June 2017, President Trump announced the USA’s withdrawal from the Paris Climate Accord, which had been ratified for less than a year, thanks in large part to the USA. That drastic shift followed the change in residency at the White House. Withdrawing from the Paris Accord presents an interesting topic for analysis. There’s the practical side of the withdrawal procedure as set out in Article 28 of the agreement, not to mention the consequences of US non-participation in addressing international climate issues. There are other international forums (Such as G8 and G20, which also have an interest in climate related topics. The Article analyses the U.S. position in negotiations and its commitments assumed the moment the United Nations Framework Convention on Climate Change (UNFCCC came into effect until now: the reduction of greenhouse gas emissions, financial aid and reporting. It also provides general analysis of national legal obligations under the Paris Accord, ratification of that agreement in general and in particularly another that took place in the USA, it focuses on the specifics of withdrawal. The specified three-year period from the Agreement becoming active, after which any party may withdraw from it (2019, is a noteworthy detail. It is well-known that the Paris Agreement provides a framework that does not impose individual national commitments or a commitment to a compliance system. In essence, and from a legal point of view, it is nonbinding. This was what allowed the USA to accept the terms of the accord relatively quickly and to use the simplified procedure, which by-passed Congress. In the opinion of the authors, President Trump’s resolution to withdraw should, possibly, be considered as a simple continuation of his election discourse and the fulfilment of a campaign promise. Additionally, President Trump’s declared intent to review the Paris Accord has legal grounds on which to launch further international negotiations

Emotional Intelligence in Patients with Spinal Cord Injury (SCI).
Saberi, Hooshang; Ghajarzadeh, Mahsa
2017-05-01
Spinal Cord Injury (SCI) is a devastating situation. Spinal Cord Injury affects functional, psychological and socioeconomic aspects of patients' lives. The ability to accomplish and explicate the one's own and other's feelings and emotions to spread over appropriate information for confirming thoughts and actions is defined as emotional intelligence (EI). The goal of this study was to evaluate depression and EI in SCI patients in comparison with healthy subjects. One-hundred-ten patients with SCI and 80 healthy subjects between Aug 2014 and Aug 2015 were enrolled. The study was conducted in Imam Hospital, Tehran, Iran. All participants were asked to fill valid and reliable Persian version Emotional Quotient inventory (EQ-i) and Beck Depression Inventory (BDI). All data were analyzed using SPSS. Data were presented as Mean±SD for continuous or frequencies for categorical variables. Continuous variables compared by means of independent sample t -test. P -values less than 0.05 were considered as significant. Mean age of patients was 28.7 and mean age of controls was 30.2 yr. Spinal cord injury in 20 (18.3%) were at cervical level, in 83 (75.4%) were thoracic and in 7 (6.3%) were lumbar. Mean values of independence, stress tolerance, self-actualization, emotional Self-Awareness, reality testing, Impulse Control, flexibility, responsibility, and assertiveness were significantly different between cases and controls. Mean values of stress tolerance, optimism, self-regard, and responsibility were significantly different between three groups with different injury level. Most scales were not significantly different between male and female cases. Emotional intelligence should be considered in SCI cases as their physical and psychological health is affected by their illness.

Timely access and ongoing delivery of care and therapeutic interventions is needed to maximize recovery and function after traumatic spinal cord injury (tSCI). To ensure these decisions are evidence-based, access to consistent, reliable, and valid sources of clinical data is required. The Access to Care and Timing Model used data from the Rick Hansen SCI Registry (RHSCIR) to generate a simulation of healthcare delivery for persons after tSCI and to test scenarios aimed at improving outcomes and reducing the economic burden of SCI. Through model development, we identified knowledge gaps and challenges in the literature and current health outcomes data collection throughout the continuum of SCI care. The objectives of this article were to describe these gaps and to provide recommendations for bridging them. Accurate information on injury severity after tSCI was hindered by difficulties in conducting neurological assessments and classifications of SCI (e.g., timing), variations in reporting, and the lack of a validated SCI-specific measure of associated injuries. There was also limited availability of reliable data on patient factors such as multi-morbidity and patient-reported measures. Knowledge gaps related to structures (e.g., protocols) and processes (e.g., costs) at each phase of care have prevented comprehensive evaluation of system performance. Addressing these knowledge gaps will enhance comparative and cost-effectiveness evaluations to inform decision-making and standards of care. Recommendations to do so were: standardize data element collection and facilitate database linkages, validate and adopt more outcome measures for SCI, and increase opportunities for collaborations with stakeholders from diverse backgrounds.

This study presents a model of an ecotechnology that combines algae cultivation with anaerobic digestion in order to recycle nutrients and to reduce the need for external energy. The concept is to convert organic waste into several products, such as electricity, biodiesel and organic fertilizer. It is labeled as the ACAD biorefinery. The simulation model of the ACAD biorefinery proved itself to be a powerful tool for understanding the symbioses and dynamics of the system, and therefore also a good tool for reaching political decisions. The model shows that the ACAD biorefinery could be totally independent of external energy supplies. Energy calculations indicate that more energy can be produced by combining the algae cultivation and anaerobic digestion processes. For every unit of energy entering the system in feedstock, 0.6 units of energy are exported as either biodiesel or electricity. The exported electricity accounts for approximately 30% of the total exported energy, while the remaining 70% is exported as biodiesel. By producing its own energy, the biorefinery improves its renewability and level of carbon neutrality. - Highlights: • The model combines algae cultivation with anaerobic digestion. • In the model nutrients and carbon dioxide are recycled. • Organic waste is converted into electrical power, biodiesel and organic fertilizer. • Results showed that more energy can be produced by combining the processes.

Modeling of biodiesel production in algae cultivation with anaerobic digestion (ACAD)
International Nuclear Information System (INIS)
Morken, John; Sapci, Zehra; Strømme, Jon Eivind T.
2013-01-01
This study presents a model of an ecotechnology that combines algae cultivation with anaerobic digestion in order to recycle nutrients and to reduce the need for external energy. The concept is to convert organic waste into several products, such as electricity, biodiesel and organic fertilizer. It is labeled as the ACAD biorefinery. The simulation model of the ACAD biorefinery proved itself to be a powerful tool for understanding the symbioses and dynamics of the system, and therefore also a good tool for reaching political decisions. The model shows that the ACAD biorefinery could be totally independent of external energy supplies. Energy calculations indicate that more energy can be produced by combining the algae cultivation and anaerobic digestion processes. For every unit of energy entering the system in feedstock, 0.6 units of energy are exported as either biodiesel or electricity. The exported electricity accounts for approximately 30% of the total exported energy, while the remaining 70% is exported as biodiesel. By producing its own energy, the biorefinery improves its renewability and level of carbon neutrality. - Highlights: • The model combines algae cultivation with anaerobic digestion. • In the model nutrients and carbon dioxide are recycled. • Organic waste is converted into electrical power, biodiesel and organic fertilizer. • Results showed that more energy can be produced by combining the processes

Could US mayors achieve the entire US Paris climate target?
Gurney, K. R.; Huang, J.; Hutchins, M.; Liang, J.
2017-12-01
After the recent US Federal Administration announcement not to adhere to the Paris Accords, 359 mayors (and counting) in the US pledged to maintain their commitments, reducing emissions within their jurisdictions by 26-28% from their 2005 levels by the year 2025. While important, this leaves a large portion of the US landscape, and a large amount of US emissions, outside of the Paris commitment. With Federal US policy looking unlikely to change, could additional effort by US cities overcome the gap in national policy and achieve the equivalent US national Paris commitment? How many cities would be required and how deep would reductions need to be? Up until now, this question could not be reliably resolved due to lack of data at the urban scale. Here, we answer this question with new data - the Vulcan V3.0 FFCO2 emissions data product - through examination of the total US energy related CO2 emissions from cities. We find that the top 500 urban areas in the US could meet the national US commitment to the Paris Accords with a reduction of roughly 30% below their 2015 levels by the year 2025. This is driven by the share of US emissions emanating from cities, particularly the largest cohort. Indeed, as the number of urban areas taking on CO2 reduction targets grows, the less the reduction burden on any individual city. In this presentation, we provide an analysis of US urban CO2 emissions and US climate policy, accounting for varying definitions of urban areas, emitting sectors and the tradeoff between the number of policy-active cities and the CO2 reduction burden.

Children are sensitive to indoor environmental pollution. Up until now there has been a lack of data on air quality in child day care centers. The aim of this study is to document the indoor environment quality of Paris child day care centers by repeated measurements, and to compare pollutant levels in child day care centers with levels in Paris dwellings. We selected 28 child day care centers frequented by a random sample of babies who participated in the PARIS birth cohort environmental investigation, and visited the child day care centers for one week twice in one year. Biological contaminants assessed were fungi, endotoxin, dust mite allergens, and chemical pollutants: aldehydes, volatile organic compounds and nitrogen dioxide (NO2). Relative humidity, temperature, and carbon dioxide levels were measured simultaneously. A standardized questionnaire was used to gather information about the buildings and their inhabitants. Airborne endotoxin levels in child day care centers were higher than those found in Paris dwellings. Dust mite allergens in child day care centers were below the threshold level for sensitization in the majority of samples, and in common with dwelling samples. Penicillium and Cladosporium were the most commonly identified genera fungi. The child day care center indoor/outdoor ratio for most chemical pollutants was above unity except for NO2, the levels for NO2 being significantly higher than those measured in homes. Chemical and biological contamination in child day care centers appears to be low, apart from endotoxin and NO2. Failure to take child exposure in child day care centers into account could result in an overestimation of children's exposure to other pollutants. Copyright © 2011 Elsevier Inc. All rights reserved.

Revision of the Paris and Brussels Conventions of Nuclear Liability
International Nuclear Information System (INIS)
Reyners, P.
2002-01-01
The Contracting Parties to the 1960 Paris Convention on Third Party Liability in the Field of Nuclear Energy and to the 1963 Brussels Convention Supplementary to the Paris Convention, have concluded this Spring four years of negotiation on the revision of these instruments. This exercise was itself started as a logical consequence of the adoption in 1997 of a revised Vienna Convention on Civil Liability for Nuclear Damage and of a Convention on Supplementary Compensation for Nuclear Damage. The Contracting Parties have concluded that the existing regime established by these Conventions remains viable and sound but that it also warrants improvements to ensure that greater financial security will be available to compensate a potentially larger number of victims in respect of a broader range of nuclear damage. A number of more technical amendments have also been agreed, in particular to ensure compatibility with other existing Conventions in this field. When the revised Paris and Brussels Conventions come into force, the total amount of funds available for compensation, provided by the liable nuclear operator and by the States concerned, will be 1.5 billion euros.

We report a 36-year-old female having lifetime exercise intolerance and lactic acidosis with nausea associated with novel compound heterozygous Acyl-CoA dehydrogenase 9 gene (ACAD9) mutations (p.Ala390Thr and p.Arg518Cys). ACAD9 is an assembly factor for the mitochondrial respiratory chain complex I. ACAD9 mutations are recognized as frequent causes of complex I deficiency. Our patient presented with exercise intolerance, rapid fatigue, and nausea since early childhood. Mild physical workload provoked the occurrence of nausea and vomiting repeatedly. Her neurological examination, laboratory findings and muscle biopsy demonstrated no abnormalities. A bicycle spiroergometry provoked significant lactic acidosis during and following exercise pointing towards a mitochondrial disorder. Subsequently, the analysis of respiratory chain enzyme activities in muscle revealed severe isolated complex I deficiency. Candidate gene sequencing revealed two novel heterozygous ACAD9 mutations. This patient report expands the mutational and phenotypic spectrum of diseases associated with mutations in ACAD9. Copyright © 2017 Elsevier B.V. All rights reserved.

Walter Benjamin e Paris: individualidade e trabalho intelectual
Directory of Open Access Journals (Sweden)
Renato Ortiz
2000-05-01
Full Text Available Este artigo é uma leitura do texto de Walter Benjamin Paris capital do século XIX. A partir do conjunto de anotações que Benjamin faz de diversos livros consultados, principalmente durante sua pesquisa na Bibliothèque Nationale, o autor pretende trabalhar a noção de indivíduo vinculando-a a dois temas. Primeiro, a emergência do flâneur como tradução do espírito de mobilidade que se inaugura com a modernidade. Para isso a discussão sobre a noção de espaço, particularmente no que diz respeito a cidade de Paris, é importante. O flâneur surge assim como um indivíduo desenraizado que se locomove através do espaço urbano remodelado. Segundo, uma aproximação entre o ato da flânerie e o trabalho intelectual. Considerando a flânerie como uma atividade intelectual o autor mostra como os temas do distanciamento e da construção do objeto são relevantes tanto para o flâneur-detetive quanto para a reflexão nas ciências sociais.This paper is an interpretation of Walter Benjamins Paris, Capital of the 19th Century. Based on the notes Benjamin made on several books he read, mainly during his research at the Bibliotèque Nationale, the author discusses the notion of the individual linking it to two themes. First, to the emergence of the flâneur as a translation of the spirit of mobility which starts with modernity. The discussion on the notion of space, especially where it concerns Paris, is essential for this analysis. The flâneur is seen as an uprooted individual who moves around the remodelled urban space. Second, to the proximity between the act of flânerie and that of intellectual work. Taking flânerie to be intellectual activity, the author shows how the themes of the distancing and the construction of the object are relevant, both to the detective-flâneur and to the reflection in social sciences.

Today's amount of freely available data requires scientists to spend large parts of their work on data management. This is especially true in environmental sciences when working with large remote sensing datasets, such as obtained from earth-observation satellites like the Sentinel fleet. Many frameworks like SpatialHadoop or Apache Spark address the scalability but target programmers rather than data analysts, and are not dedicated to imagery or array data. In this work, we use the open-source data management and analytics system SciDB to bring large earth-observation datasets closer to analysts. Its underlying data representation as multidimensional arrays fits naturally to earth-observation datasets, distributes storage and computational load over multiple instances by multidimensional chunking, and also enables efficient time-series based analyses, which is usually difficult using file- or tile-based approaches. Existing interfaces to R and Python furthermore allow for scalable analytics with relatively little learning effort. However, interfacing SciDB and file-based earth-observation datasets that come as tiled temporal snapshots requires a lot of manual bookkeeping during ingestion, and SciDB natively only supports loading data from CSV-like and custom binary formatted files, which currently limits its practical use in earth-observation analytics. To make it easier to work with large multi-temporal datasets in SciDB, we developed software tools that enrich SciDB with earth observation metadata and allow working with commonly used file formats: (i) the SciDB extension library scidb4geo simplifies working with spatiotemporal arrays by adding relevant metadata to the database and (ii) the Geospatial Data Abstraction Library (GDAL) driver implementation scidb4gdal allows to ingest and export remote sensing imagery from and to a large number of file formats. Using added metadata on temporal resolution and coverage, the GDAL driver supports time-based ingestion of

Paris saponins possess anticancer, anti-inflammatory, and antiviral effects. However, the anticancer effect of Paris saponins has not been well elucidated and the mechanisms underlying the potential function of Paris saponins in cancer therapy are needed to be further identify. In this study, we report that saponin compounds isolated from Paris polyphylla exhibited antitumor activity against breast cancer cell lines, MCF-7 and MDA-MB-231. Paris saponin XA-2 induced apoptosis in both cell lines, as evidenced by the activation of caspases and cleavage of Poly (ADP-ribose) polymerase. The ability of XA-2 to induce autophagy was confirmed by acridine orange staining, accumulation of autophagosome-bound Long chain 3 (LC3)-II, and measurement of autophagic flux. XA-2-induced autophagy was observed to promote apoptosis by the combined treatment of breast cancer cell lines with XA-2 and autophagy inhibitors 3-methyladenine and bafilomycin A1, respectively. Moreover, we report a decrease in the levels of Akt/mTOR signaling pathway proteins, such as the phosphorylated forms of Akt, mTOR, P70S6K, and eukaryotic translation initiation factor 4E-binding protein 1 (4EBP1). Taken together, these results provide important insights explaining the anticancer activity of Paris saponins and the potential development of XA-2 as a new therapeutic agent.

To decide on the optimum artificial domestication cultivation light environment for Paris polyphylla var. chinensis through investigating the effect of light intensity on leaf's gas exchange parameters, photosynthetic parameters, light saturation point and compensation point of Paris polyphylla var. chinensis. Different low-light stress gradients' effect on the growth of Paris polyphylla var. chinensis was compared with no low-light stress treatment through calculating leaf's gas exchange parameters, photosynthetic parameters, light saturation point and compensation point, and then all these parameters were statistically analyzed. Light intensity had significant influence on the photosynthetic characteristics of Paris polyphylla var. chinensis. With the strengthening of the low-light stress, chlorophyll content, gas exchange parameters, photosynthetic parameters P., AQY and light saturation point all gradually increased at first, and then decreased. However, both photosynthetic parameters Rd and light compensation point firstly decreased and then rose again. These results showed that too strong or too weak light intensity affected the optimization of photosynthetic parameters of Paris polyphylla var. chinensis. The optimal illuminance for each parameter was not completely same, but they could all reach a relative ideal state when the shading ranges between 40% and 60%. However, photosynthetic parameters deteriorated rapidly when the shading surpass 80%. For artificially cultivating Paris polyphylla var. chinensis in Baoxing,Sichuan or the similar ecological region, shading 40%-60% is the optimal light environment, which can enhance the photosynthesis of Paris polyphylla var. chinensis and promote the accumulation of photosynthetic products.

¿Puede amortiguar el Engagement los efectos nocivos de la Procrastinación Académica?
Directory of Open Access Journals (Sweden)
Marcela Paz González-Brignardello
2013-06-01
Full Text Available El propósito de este estudio es explorar la relación existente entre la Procrastinación Académica y el Engagement, así como el patrón de funcionamiento de ambas variables en entornos académicos, en relación al uso de estrategias de aprendizaje autorregulado, eficientes y deficientes, y el estado de los estudiantes previo a la realización de los exámenes. Todas las variables han sido medidas a través de cuestionarios de autoinforme, en una población de universitarios en modalidad a distancia/en línea. Asimismo, se postula un posible efecto de amortiguación o buffering del Engagement sobre los efectos nocivos de la Procrastinación Académica. Este patrón diferencial se analiza con mayor precisión mediante la consideración de tres perfiles de estudiantes, los caracterizados por Engagement puro, los caracterizados por Procrastinación Académica pura, y un perfil mixto de procrastinadores con niveles de Engagement medio-alto. Los resultados obtenidos corroboran, por un lado, las grandes diferencias existentes en la forma de afrontar los estudios entre los estudiantes engaged y los procrastinadores y, por otro, el claro efecto amortiguador del engagement sobre la Procrastinación Académica, observándose en el perfil mixto una mejora significativa de carácter positivo, tanto en el tipo de estrategias de aprendizaje autorregulado utilizadas, como en su estado previo a los exámenes.

O estudo está fundamentado nos trabalhos de Baldridge, Cohen e March, Weick, Keller, Hardy, Langley, Mintzberg e Rose, Hardy e Fachin, Birnbaum, Mintzberg e Meyer Jr., que destacam diversos fatores que fazem das universidades organizações complexas, atípicas e com implicações em seu gerenciamento. Trata-se de um estudo de caso que teve como foco de análise estratégias acadêmicas relevantes no período de 2001-2008. Os dados foram coletados junto às seguintes fontes: dados organizacionais, observações não participantes e entrevistas com base em narrativas com cinco gestores. A análise revela a presença de estratégias acadêmicas emanadas da administração superior do tipo “guarda-chuva”. As principais estratégias acadêmicas, de natureza emergente, surgem por iniciativas individuais e de pequenos grupos com a influência de aspectos racionais, políticos e simbólicos. As mais destacadas conclusões apontam para um discurso da administração superior centrado na racionalidade da gestão, privilegiando modelos empresariais incompatíveis com a realidade complexa da universidade. Revelou-se uma gestão acadêmica amadora, incremental e promotora de iniciativas estratégicas emergentes, com resultados significativos para o desempenho dos programas acadêmicos e da instituição.

2015-03-01
Full Text Available Sobre la base del análisis de una historia personal de desplazamiento entre academias (peruana y chilena, y la reinvención y el contrabando que toda migración supone, este artículo argumenta de qué manera frente a las nuevas modalidades de evaluación (los rankings, la búsqueda de isomorfismo de las estructuras argumentativas y las formas lingüísticas o incluso la ficción de sociologías globales, se mantienen vivas culturas académicas particulares. En este marco, la reflexión se organiza mostrando que detrás de la singularidad de los estilos intelectuales, formas de sociabilidad profesionales e incluso formas lingüísticas de cada una de ellas, lo que se revela es la manera como cada cultura académica local responde desde tradiciones diversas a desafíos político sociales distintos y con ello su rol de compromiso público y crítico.

A spinal cord injury disease management protocol (SCI DMP) was developed to address the unique medical, physical, functional, and psychosocial needs of those living with spinal cord injuries and disorders (SCI/D). The SCI DMP was piloted to evaluate DMP clinical content and to identify issues for broader implementation across the Veterans Affairs (VA) SCI System of Care. Thirty-three patients with SCI/D from four VA SCI centers participated in a 6-month pilot. Patients received customized SCI DMP questions through a data messaging device (DMD). Nurse home telehealth care coordinators (HTCC) monitored responses and addressed clinical alerts daily. One site administered the Duke Severity of Illness (DUSOI) Checklist and Short Form-8 (SF-8™) to evaluate the changes in comorbidity severity and health-related quality of life while on the SCI DMP. Patients remained enrolled an average of 116 days, with a mean response rate of 56%. The average distance between patient's home and their VA SCI center was 59 miles. Feedback on SCI DMP content and the DMD included requests for additional clinical topics, changes in administration frequency, and adapting the DMD for functional impairments. Improvement in clinical outcomes was seen in a subset of patients enrolled on the SCI DMP. SCI HTCCs and patients reported that the program was most beneficial for newly injured patients recently discharged from acute rehabilitation that live far from specialty SCI care facilities. SCI DMP content changes and broader implementation strategies are currently being evaluated based on lessons learned from the pilot.

Full Text Available Known in the ambiance of the Romanian art of the interwar period as one of the most talented painters, Auguste Baillayre also asserted himself as an excellent professor. His pedagogical activity has known, from the very start, brilliant achievements. Having received European studies, those over 30 students in his studio, whom Auguste Baillayre remembers in 1961, did not return to Bessarabia. Olesi Hršanovschi-Beassley (Olga Olby, Lydia Luzanovsky, Gregoire Michonze, Antoine Irisse and Joseph Bronstein studied in Paris, Felix Roitman, Helen Barlo and Natalia Bragalia – in Brussels, Elisabeth Ivanovsky, Nina Jascinsky and Nicolae Coleadici in Amsterdam. Theodor Kiriacoff worked in Romania, in Iasi and then in Bucharest, where Helen Barlo and Natalia Bragalia return after studying in France, Gheorghe Ceglocoff comes from Dresden and Galina Ceaşcenco creates her works in Prague. These are all remarkable plastic artists who affirmed themselves outside the Bessarabian borders. Their studies at the art academies „La Grand Chaumière”, „École Nationale Supérieure des Arts Décoratifs”, „Académie Julian”, „Académie Ranson” in Paris, „Académie Royale de Beaux-Arts” in Brussels, and „Académie de Beaux-Arts” in Dresden have demonstrated the professional level of Auguste Baillayre’s disciples.

Guihan, Marylou; Murphy, Deidre; Rogers, Thea J; Parachuri, Ramadevi; Sae Richardson, Michael; Lee, Kenneth K; Bates-Jensen, Barbara M
2016-05-01
Community-acquired pressure ulcers (PrUs) are a frequent cause of hospitalization of Veterans with spinal cord injury (SCI). The Veterans Health Administration (VHA) recommends that SCI annual evaluations include assessment of PrU risk factors, a thorough skin inspection and sharing of recommendations for PrU prevention strategies. We characterized consistency of preventive skin care during annual evaluations for Veterans with SCI as a first step in identifying strategies to more actively promote PrU prevention care in other healthcare encounters. Retrospective cross-sectional observational design, including review of electronic medical records for 206 Veterans with SCI admitted to 2 VA SCI centers from January-December, 2011. Proportion of applicable skin health elements documented (number of applicable elements/skin health elements documented). Our sample was primarily white (78%) male (96.1%), and mean age = 61 years. 40% of participants' were hospitalized for PrU treatment, with a mean of 294 days (median = 345 days) from annual evaluation to the index admission. On average, Veterans received an average of 75.5% (IQR 68-86%) of applicable skin health elements. Documentation of applicable skin health elements was significantly higher during inpatient vs. outpatient annual evaluations (mean elements received = 80.3% and 64.3%, respectively, P > 0.001). No significant differences were observed in documentation of skin health elements by Veterans at high vs. low PrU risk. Additional PrU preventive care in the VHA outpatient setting may increase identification and detection of PrU risk factors and early PrU damage for Veterans with SCI in the community, allowing for earlier intervention.

Full Text Available Este estudio presenta los resultados sobre la relación que existe entre las autoatribuciones académicas en lenguaje y matemáticas en una muestra de 2.022 estudiantes de Educación Secundaria de 12 a 16 años. Los adolescentes fueron seleccionados aleatoriamente de 20 escuelas urbanas y rurales en las provincias de Alicante y Murcia, España. La conducta prosocial fue codificada con el Teenage Inventory of Social Skills y las autoatribuciones académicas fueron medidas mediante la Escala de Atribución Causal de Sydney (Sydney Attribution Scale, SAS; Marsh, 1984. El 17.35% de estudiantes de ESO fueron identificados como prosociales. Los chicos de 2º de ESO y las chicas de 4º de ESO presentaron la menor y mayor prevalencia puntual de conducta prosocial, respectivamente. Respecto a la asignatura de lenguaje, los estudiantes prosociales atribuyen significativamente el éxito a la capacidad, el esfuerzo y, en menor medida, a causas externas. En cuanto a la asignatura de matemáticas, los estudiantes prosociales atribuyeron el éxito significativamente más al esfuerzo y significativamente menos a causas externas, mientras que atribuyeron el fracaso significativamente más a la falta de esfuerzo. Además, los datos han permitido crear un modelo de regresión logística que permite hacer estimaciones correctas respecto a la probabilidad de éxito académico en matemáticas, en lenguaje y en todas las asignaturas aprobadas en estudiantes prosociales de E.S.O. a partir de las puntuaciones en atribuciones académicas.

Elaborating Article 15 of the Paris Agreement: Facilitating Implementation and Promoting Compliance
International Nuclear Information System (INIS)
Biniaz, Susan
2017-10-01
As climate negotiations reopen on November, 6 at COP23 in Bonn to advance the concrete implementation of the different provisions of the Paris Agreement, this paper aims to take stock of the open questions of Article 15. They concern the role of the Committee responsible for 'facilitating compliance and promoting implementation'. First, the paper outlines what was already decided in Paris in 2015 as well as the issues still to be resolved by the end of 2018. These include the scope of its application, the means to initiate Article 15 as well as the outcomes that the committee can produce and the tools it should have at its disposal. Keeping in mind Paris Agreement's uniqueness and its philosophy, the author attempts to identify the added value of Article 15's mechanism and suggests ways to address the respective expectations and concerns of Parties, in order to progress towards a consensual resolution that is acceptable to a large number of Parties

Test the effect of a multi-joint control with implanted electrical stimulation on walking after spinal cord injury (SCI). Single subject research design with repeated measures. Hospital-based biomechanics laboratory and user assessment of community use. Female with C6 AIS C SCI 30 years post injury. Lower extremity muscle activation with an implanted pulse generator and gait training. Walking speed, maximum distance, oxygen consumption, upper extremity (UE) forces, kinematics and self-assessment of technology. Short distance walking speed at one-year follow up with or without stimulation was not significantly different from baseline. However, average walking speed was significantly faster (0.22 m/s) with stimulation over longer distances than volitional walking (0.12 m/s). In addition, there was a 413% increase in walking distance from 95 m volitionally to 488 m with stimulation while oxygen consumption and maximum upper extremity forces decreased by 22 and 16%, respectively. Stimulation also produced significant (P ≤ 0.001) improvements in peak hip and knee flexion, ankle angle at foot off and at mid-swing. An implanted neuroprosthesis enabled a subject with incomplete SCI to walk longer distances with improved hip and knee flexion and ankle dorsiflexion resulting in decreased oxygen consumption and UE support. Further research is required to determine the robustness, generalizability and functional implications of implanted neuroprostheses for community ambulation after incomplete SCI.

Antidepressants Are Effective in Decreasing Neuropathic Pain After SCI: A Meta-Analysis.
Mehta, Swati; Guy, Stacey; Lam, Tracey; Teasell, Robert; Loh, Eldon
2015-01-01
To systematically review and assess the effectiveness and safety of antidepressants for neuropathic pain among individuals with spinal cord injury (SCI). A systematic search was conducted using multiple databases for relevant articles published from 1980 to April 2014. Randomized controlled trials (RCTs) involving antidepressant treatment of neuropathic pain with ≥ 3 individuals and ≥ 50% of study population with SCI were included. Two independent reviewers selected studies based on inclusion criteria and then extracted data. Pooled analysis using Cohen's d to calculate standardized mean difference, standard error, and 95% confidence interval for primary (pain) and other secondary outcomes was conducted. Four RCTs met inclusion criteria. Of these, 2 studies assessed amitriptyline, 1 trazadone, and 1 duloxetine among individuals with neuropathic SCI pain. A small effect was seen in the effectiveness of antidepressants in decreasing pain among individuals with SCI (standardized mean difference = 0.34 ± 0.15; 95% CI, 0.05-0.62; P = .02). A number needed to treat of 3.4 for 30% or more pain relief was found by pooling 2 studies. Of these, significantly higher risk of experiencing constipation (risk ratio [RR] = 1.74; 95% CI, 1.09-2.78; P = .02) and dry mouth (RR = 1.39; 95% CI, 1.04-1.85; P = .02) was found amongst individuals receiving antidepressant treatment compared to those in the control group. The current meta-analysis demonstrates that antidepressants are effective in reducing neuropathic SCI pain. However, this should be interpreted with caution due to the limited number of studies. Further evaluation of long-term therapeutic options may be required.

Paris and its long-term temperature goal: First steps on a long road
Rogelj, J.
2017-12-01
As a means to achieve its long-term temperature goal, the Paris Agreement put in place a system of regularly updated country pledges alternating with global stocktaking exercises that assess progress towards achieving the Paris goals. By now, the vast majority of countries have submitted their intended actions (also known as Nationally Determined Contributions - NDCs). This begs the question what these amount to and whether they are in line with the agreement`s long-term temperature goal. A structured sensitivity analysis of the emissions implications of the Paris pledges has been carried out, showing that the ambiguity and imprecision of the NDCs leaves open a wide range of possible outcomes by 2030. This range has important implications for the feasibility and cost of pathways that attempt to limit warming to the temperature goals of the Agreement. We identify salient steps to reduce the overall uncertainty, and explore the minimum requirements that have to be met for integrated energy-economy-land models to still find options to stay within the temperature limits of the Paris Agreement. These requirements come under the form of near-term emissions reductions, and assumptions about the deployment of carbon-dioxide removal technologies in the second half of the century.

The Paris Agreement: end of the climate multilateralism crisis or evolution in chiaroscuro?
International Nuclear Information System (INIS)
Lavallee, Sophie; Maljean-Dubois, Sandrine
2016-01-01
After a decade of chaotic negotiations, the twenty-first Conference of Parties to the United Nations Framework Convention on Climate Change managed on 12 December 12 2015 to agree on the text of an international treaty, the Paris Agreement, preceded by a COP decision aiming both to explain and prepare the entry into force of the treaty. Is this compromise text marking a significant step or is it a weak agreement incapable to alter our medium and long term trajectories of emissions of greenhouse gases? Tracing the process that led to its adoption helps to better understand the substantive and procedural contribution of the Paris agreement, without denying its limits. As a new brick in the complex architecture of the climate regime, the Paris Agreement is more the beginning of a new era for climate diplomacy, full of uncertainties, than a final stage

to inhibit homologous recombination (HR) events. Here, we describe a biochemical mechanism in which PARI functions as an HR regulator after replication fork stalling and during double-strand break repair. In our reconstituted biochemical system, we show that PARI inhibits DNA repair synthesis during...... recombination events in a PCNA interaction-dependent way but independently of its UvrD-like helicase domain. In accordance, we demonstrate that PARI inhibits HR in vivo, and its knockdown suppresses the UV sensitivity of RAD18-depleted cells. Our data reveal a novel human regulatory mechanism that limits...

Ibn Tufail as a SciArtist in the Treatise of Hayy Ibn Yaqzan
Directory of Open Access Journals (Sweden)
Nadia Maftouni
2017-12-01
Full Text Available Ibn Tufail as a scientist as well as an artist exposes the issues of human anatomy, autopsy, and vivisection and, thereby, could be regarded as a SciArtist. SciArt might be defined as a reciprocal relation between art and science. Followings are the kinds of these interactions: artistically-inclined scientific activities,science-minded artistic activities, and intertwined scientific and artistic activities. In their fictional treatises, Avicenna, Ibn Tufail, and Suhrawardi are traditional avatars of SciArt. This paper frames an account of SciArt, suggesting in detail Ibn Tufail’s work as a prototypical example, while Avicenna and Suhrawardi go beyond the scope of this paper. An instant of intertwined scientific and artistic activities strongly captivates the attentions to Ibn Tufail, describing human anatomy, autopsy, and vivisection in his Treatiseof Hay Ibn Yaqzan. Recognized as the first philosophical story, Hay Ibn Yaqzan depicts the whole philosophy of Ibn Tufail by the story of an autodidactic feral child a gazelle raised whom in an island in the Indian Ocean.

Full Text Available El fracaso académico es un problema que afrontan los estudiantes quepresentan un rendimiento académico deficiente, lo cual los lleva en pocotiempo a desertar o son expulsados del sistema educativo. Se considera que es un problema multicausal, pero para afrontarlo es necesario indagar desde los mismos estudiantes qué es lo que más los puede estar afectando.Para indagar sobre los factores asociados a este problema se llevó a cabo un estudio descriptivo con estudiantes de psicología en una universidad privada de Barranquilla (Colombia. Se entrevistó a 38 estudiantes que asistían a un programa exclusivo para aquellos con muy bajo rendimiento académico y que estaban en riesgo de salir del programa o habían sido remitidos por los profesores. Los resultados indican que los estudiantes no recibieron una orientación vocacional adecuada antes de ingresar a los estudios superiores que les permitiera analizar sus capacidades y habilidades con respecto a una carrera profesional. Además manifiestan limitaciones en sus competencias de concentración y atención, en la distribución del tiempo, en la deficiente utilización de técnicas de estudio, y en la poca asistencia a clases por la baja motivación en las actividades académicas. La relación con su familia la consideraron satisfactoria. Se observa que las acciones para reducir el fracaso deben ser emprendidas antes del ingreso a la universidad, con estrategias de estudio y afrontamiento que les brinden a los jóvenes las mejores opciones entre sus intereses y capacidades con las oportunidades que les ofrece la sociedad en la cual vivirán.

Improvement in Student Science Proficiency Through InSciEd Out
Sonju, James D.; Leicester, Jean E.; Hoody, Maggie; LaBounty, Thomas J.; Frimannsdottir, Katrin R.; Ekker, Stephen C.
2012-01-01
Abstract Integrated Science Education Outreach (InSciEd Out) is a collaboration formed between Mayo Clinic, Winona State University, and Rochester Public Schools (MN) with the shared vision of achieving excellence in science education. InSciEd Out employs an equitable partnership model between scientists, teachers, education researchers, and the community. Teams of teachers from all disciplines within a single school experience cutting-edge science using the zebrafish model system, as well as current pedagogical methods, during a summer internship at the Mayo Clinic. Within the internship, the teachers produce new curriculum that directly addresses opportunities for science education improvement at their own school. Zebrafish are introduced within the new curriculum to support a living model of the practice of science. Following partnership with the InSciEd Out program and 2 years of implementation in the classroom, teacher-interns from a K–8 public school reported access to local scientific technology and expertise they had not previously recognized. Teachers also reported improved integration of other disciplines into the scientific curriculum and a flow of concepts vertically from K through 8. Students more than doubled selection of an Honors science track in high school to nearly 90%. 98% of students who took the Minnesota Comprehensive Assessments in their 5th and 8th grade year (a span that includes 2 years of InSciEd Out) showed medium or high growth in science proficiency. These metrics indicate that cooperation between educators and scientists can result in positive change in student science proficiency and demonstrate that a higher expectation in science education can be achieved in US public schools.

Background. A quadratic formula of the Spinal Cord Injury Ability Realization Measurement Index (SCI-ARMI) has previously been published. This formula was based on a model of Spinal Cord Independence Measure (SCIM95), the 95th percentile of the SCIM III values, which correspond with the American Spinal Injury Association Motor Scores (AMS) of SCI patients. Objective. To further develop the original formula. Setting. Spinal cord injury centers from 6 countries and the Statistical Laboratory, Tel-Aviv University, Israel. Methods. SCIM95 of 661 SCI patients was modeled, using a quantile regression with or without adjustment for age and gender, to calculate SCI-ARMI values. SCI-ARMI gain during rehabilitation and its correlations were examined. Results. A new quadratic SCIM95 model was created. This resembled the previously published model, which yielded similar SCIM95 values in all the countries, after adjustment for age and gender. Without this adjustment, however, only 86% of the non-Israeli SCIM III observations were lower than those SCIM95 values (P .1). SCI-ARMI gain was positive (38.8 ± 22 points, P SCI-ARMI formula is valid for an international population after adjustment for age and gender. The new formula considers more factors that affect functional ability following SCI. © The Author(s) 2014.

Science classroom inquiry (SCI simulations: a novel method to scaffold science learning.
Directory of Open Access Journals (Sweden)
Melanie E Peffer
Full Text Available Science education is progressively more focused on employing inquiry-based learning methods in the classroom and increasing scientific literacy among students. However, due to time and resource constraints, many classroom science activities and laboratory experiments focus on simple inquiry, with a step-by-step approach to reach predetermined outcomes. The science classroom inquiry (SCI simulations were designed to give students real life, authentic science experiences within the confines of a typical classroom. The SCI simulations allow students to engage with a science problem in a meaningful, inquiry-based manner. Three discrete SCI simulations were created as website applications for use with middle school and high school students. For each simulation, students were tasked with solving a scientific problem through investigation and hypothesis testing. After completion of the simulation, 67% of students reported a change in how they perceived authentic science practices, specifically related to the complex and dynamic nature of scientific research and how scientists approach problems. Moreover, 80% of the students who did not report a change in how they viewed the practice of science indicated that the simulation confirmed or strengthened their prior understanding. Additionally, we found a statistically significant positive correlation between students' self-reported changes in understanding of authentic science practices and the degree to which each simulation benefitted learning. Since SCI simulations were effective in promoting both student learning and student understanding of authentic science practices with both middle and high school students, we propose that SCI simulations are a valuable and versatile technology that can be used to educate and inspire a wide range of science students on the real-world complexities inherent in scientific study.

Peffer, Melanie E; Beckler, Matthew L; Schunn, Christian; Renken, Maggie; Revak, Amanda
2015-01-01
Science education is progressively more focused on employing inquiry-based learning methods in the classroom and increasing scientific literacy among students. However, due to time and resource constraints, many classroom science activities and laboratory experiments focus on simple inquiry, with a step-by-step approach to reach predetermined outcomes. The science classroom inquiry (SCI) simulations were designed to give students real life, authentic science experiences within the confines of a typical classroom. The SCI simulations allow students to engage with a science problem in a meaningful, inquiry-based manner. Three discrete SCI simulations were created as website applications for use with middle school and high school students. For each simulation, students were tasked with solving a scientific problem through investigation and hypothesis testing. After completion of the simulation, 67% of students reported a change in how they perceived authentic science practices, specifically related to the complex and dynamic nature of scientific research and how scientists approach problems. Moreover, 80% of the students who did not report a change in how they viewed the practice of science indicated that the simulation confirmed or strengthened their prior understanding. Additionally, we found a statistically significant positive correlation between students' self-reported changes in understanding of authentic science practices and the degree to which each simulation benefitted learning. Since SCI simulations were effective in promoting both student learning and student understanding of authentic science practices with both middle and high school students, we propose that SCI simulations are a valuable and versatile technology that can be used to educate and inspire a wide range of science students on the real-world complexities inherent in scientific study.

Astronomical Data Processing Using SciQL, an SQL Based Query Language for Array Data
Zhang, Y.; Scheers, B.; Kersten, M.; Ivanova, M.; Nes, N.
2012-09-01
SciQL (pronounced as ‘cycle’) is a novel SQL-based array query language for scientific applications with both tables and arrays as first class citizens. SciQL lowers the entrance fee of adopting relational DBMS (RDBMS) in scientific domains, because it includes functionality often only found in mathematics software packages. In this paper, we demonstrate the usefulness of SciQL for astronomical data processing using examples from the Transient Key Project of the LOFAR radio telescope. In particular, how the LOFAR light-curve database of all detected sources can be constructed, by correlating sources across the spatial, frequency, time and polarisation domains.

Revision of the Paris Convention from the German point of view
International Nuclear Information System (INIS)
Mahlmann, Wilfried.
1977-01-01
The paper discusses the revision of the Paris Convention from the German point of view and states how this country has used the possibilities for exceptions provided under the Convention so that German nuclear third party liability legislation differs somewhat from the standards laid down in the Convention. This is explained by a desire to provide increased financial security for the population concerned. After describing various proposed procedures for increasing liability amounts in the Paris Convention and the Brussels Supplementary Convention the author concludes that his country would welcome a revision of the Conventions which would provide increased financial security for the public.

SciJourn is magic: construction of a science journalism community of practice
Nicholas, Celeste R.
2017-06-01
This article is the first to describe the discoursal construction of an adolescent community of practice (CoP) in a non-school setting. CoPs can provide optimal learning environments. The adolescent community centered around science journalism and positioned itself dichotomously in relationship to school literacy practices. The analysis focuses on recordings from a panel-style research interview from an early implementation of the Science Literacy Through Science Journalism (SciJourn) project. Researchers trained high school students participating in a youth development program to write science news articles. Students engaged in the authentic practices of professional science journalists, received feedback from a professional editor, and submitted articles for publication. I used a fine-grained critical discourse analysis of genre, discourse, and style to analyze student responses about differences between writing in SciJourn and in school. Students described themselves as agentic in SciJourn and passive in school, using an academic writing discourse of deficit to describe schooling experiences. They affiliated with and defined a SciJourn CoP, constructing positive journalistic identities therein. Educators are encouraged to develop similar CoPs. The discursive features presented may be used to monitor the development of communities of practice in a variety of settings.

Overview of the Scalable Coherent Interface, IEEE STD 1596 (SCI)
International Nuclear Information System (INIS)
Gustavson, D.B.; James, D.V.; Wiggers, H.A.
1992-10-01
The Scalable Coherent Interface standard defines a new generation of interconnection that spans the full range from supercomputer memory 'bus' to campus-wide network. SCI provides bus-like services and a shared-memory software model while using an underlying, packet protocol on many independent communication links. Initially these links are 1 GByte/s (wires) and 1 GBit/s (fiber), but the protocol scales well to future faster or lower-cost technologies. The interconnect may use switches, meshes, and rings. The SCI distributed-shared-memory model is simple and versatile, enabling for the first time a smooth integration of highly parallel multiprocessors, workstations, personal computers, I/O, networking and data acquisition

Full Text Available La posibilidad de acceso a Internet determina diferencias, incomprensiones y marginalidades que trascienden hacia lo educativo. No obstante, la red está presente, su penetración ineludible define cierta extensión virtual. Estar excluido del ciberespacio demuestra marginalidad y al contrario, para quienes allí tienen hábitos de estudio las potencialidades académicas e investigativas les resultan significativas. Otro problema, además de la marginalidad, se relaciona con las diferencias entre los nativos digitales y los demás. Los hábitos, lenguajes y posiciones disjuntas determinan incomprensiones y juzgamientos apresurados. Es el caso de la cultura digital de los estudiantes universitarios, que determina formas de construcción académica no siempre acordes con la tradición de sus profesores.

Full Text Available The author points to the overall context of the discussion about the problems related to Climate change. The paper analyzes the provisions of the Paris Agreement, adopted on the 21st Conference of the Parties of the UN Framework Convention on Climate Change (Paris, December, 2015. The overall context of the discussion is determined by the content and significance of the objectives and principles defined in the Paris Agreement in relation to the goals and principles of the contemporary policy and environmental law in general. Particular emphasis is given to the place and importance of the objectives related to human rights (the right to a healthy environment and sustainable development. The central part of the paper examines the significance of the objectives and principles in the field of the climate change that are contained in the provisions of the UN Framework Convention on Climate Change with the Kyoto Protocol and other relevant international agreements relevant to climate change that were adopted prior to the Paris Agreement. Further on, the provisions of the Paris Agreement are analyzed, and in particular the parts relating to the objectives and principles. The last part of the paper gives an overview of the relevance of the solutions contained in the Paris Agreement for the Republic of Serbia. Paper provides an overview of the basic strategic and normative elements of national policy in the field of climate change, including the question of objectives and principles. In addition to that it considers the thesis that Paris agreement, aside from the elements of the continuity as the successor of the Kyoto protocol, contains a new element regarding goals and principles of international community's activities in the climate change field.

Ice-free Arctic projections under the Paris Agreement
Sigmond, Michael; Fyfe, John C.; Swart, Neil C.
2018-05-01
Under the Paris Agreement, emissions scenarios are pursued that would stabilize the global mean temperature at 1.5-2.0 °C above pre-industrial levels, but current emission reduction policies are expected to limit warming by 2100 to approximately 3.0 °C. Whether such emissions scenarios would prevent a summer sea-ice-free Arctic is unknown. Here we employ stabilized warming simulations with an Earth System Model to obtain sea-ice projections under stabilized global warming, and correct biases in mean sea-ice coverage by constraining with observations. Although there is some sensitivity to details in the constraining method, the observationally constrained projections suggest that the benefits of going from 2.0 °C to 1.5 °C stabilized warming are substantial; an eightfold decrease in the frequency of ice-free conditions is expected, from once in every five to once in every forty years. Under 3.0 °C global mean warming, however, permanent summer ice-free conditions are likely, which emphasizes the need for nations to increase their commitments to the Paris Agreement.

To develop a calibrated item bank and computer adaptive test (CAT) to assess the effects of stigma on health-related quality of life in individuals with spinal cord injury (SCI). Grounded-theory based qualitative item development methods, large-scale item calibration field testing, confirmatory factor analysis, and item response theory (IRT)-based psychometric analyses. Five SCI Model System centers and one Department of Veterans Affairs medical center in the United States. Adults with traumatic SCI. SCI-QOL Stigma Item Bank A sample of 611 individuals with traumatic SCI completed 30 items assessing SCI-related stigma. After 7 items were iteratively removed, factor analyses confirmed a unidimensional pool of items. Graded Response Model IRT analyses were used to estimate slopes and thresholds for the final 23 items. The SCI-QOL Stigma item bank is unique not only in the assessment of SCI-related stigma but also in the inclusion of individuals with SCI in all phases of its development. Use of confirmatory factor analytic and IRT methods provide flexibility and precision of measurement. The item bank may be administered as a CAT or as a 10-item fixed-length short form and can be used for research and clinical applications.

Kleptomania presents difficulties in diagnosis for clinicians. This study aimed to develop and test a DSM-IV-based diagnostic instrument for kleptomania. To assess for current kleptomania the Structured Clinical Interview for Kleptomania (SCI-K) was administered to 112 consecutive subjects requesting psychiatric outpatient treatment for a variety of disorders. Reliability and validity were determined. Classification accuracy was examined using the longitudinal course of illness. The SCI-K demonstrated excellent test-retest (Phi coefficient = 0.956 (95% CI = 0.937, 0.970)) and inter-rater reliability (phi coefficient = 0.718 (95% CI = 0.506, 0.848)) in the diagnosis of kleptomania. Concurrent validity was observed with a self-report measure using DSM-IV kleptomania criteria (phi coefficient = 0.769 (95% CI = 0.653, 0.850)). Discriminant validity was observed with a measure of depression (point biserial coefficient = -0.020 (95% CI = -0.205, 0.166)). The SCI-K demonstrated both high sensitivity and specificity based on longitudinal assessment. The SCI-K demonstrated excellent reliability and validity in diagnosing kleptomania in subjects presenting with various psychiatric problems. These findings require replication in larger groups, including non-psychiatric populations, to examine their generalizability. Copyright (c) 2006 John Wiley & Sons, Ltd.

Ertapenem-associated neurotoxicity in the Spinal Cord Injury (SCI) population: a case series.
Patel, Ursula C; Fowler, Mallory A
2017-09-06
Context Ertapenem, a broad spectrum carbapenem antibiotic, is used often in Spinal Cord Injury (SCI) patients due to increased risk factors for multi-drug resistant (MDR) infections in this population. Neurotoxicity, specifically seizures, due to ertapenem is a known adverse effect and has been described previously. Other manifestations such as delirium and visual hallucinations have rarely been reported, and no literature, to the best of our knowledge, specifically describes these effects solely in the SCI population. Findings Four cases of mental status changes and hallucinations in SCI patients attributed to ertapenem therapy are described. Onset of symptoms began between one and six days following initiation of ertapenem and resolved between two to 42 days following discontinuation. Based on the Naranjo probability scale, a probable relationship exists between the adverse events and ertapenem for three out of the four cases. Possible overestimation of renal function and hypoalbuminemia may be contributing factors to the noted adverse reactions. Conclusion/Clinical Relevance The cases described highlight the importance of recognizing ertapenem-associated hallucinations in SCI patients. The population is particularly vulnerable due to risk factors for MDR infections necessitating ertapenem use, possible overestimation of renal function, and a high prevalence of hypoalbuminemia.

The number of papers published in SCI (Science Citation Index) journal is used as a standard for evaluating the level of science technology and a comparative ranking among countries; thus, the journal of the Korean Nuclear Society (KNS), in the SCI. For the SCI, there are 3,750 journals of core (standard) and 4,824 journals of expanded versions; however, NET belongs to the expanded version. As of January 2014, only 12 Korean journals were listed in the SCI core journals and 90 journals were listed in the expanded version. In order for NET of KNS to grow as an international journal, it must be listed in the SCI. With a view to pursuing this goal, it is imperative to undertake the following efforts. First, many good papers should be attracted. That is, the publication of invited papers should be promoted, and a special edition should be issued with the inclusion of prestigious scientists in Korea and overseas who are able to raise the If. Also, a contributor should be given direct and indirect incentives, and above all, academic personnel should be actively involved. Second, internationalization of the journals is needed. In other words, the authors, editors, and reviewers should be more international. In particular, the activities of foreign editors should be fortified. Third, promotion should b reinforced. That is, an independent web site of NET should be operated, and in particular, a paper submission system should be composed scientifically. Fourth, the society system should be improved. In other words, for many good papers to be submitted, an institutional improvement is required to revise the regulations under which the results of a citation analysis can be reflected and to strengthen the activities of the editing committee.

Background : Research has shown that employment following spinal cord injury (SCI) is related to health and functioning, with physical health and functioning after SCI frequently identified as a primary barrier to employment. Objective: To examine the relationship between employment and behaviors associated with the management of physical health and functioning as described by individuals with SCI who have been employed post injury. Methods: A qualitative approach using 6 focus groups at 2 sites included 44 participants with SCI who had worked at some time post injury. Heterogeneous and homogeneous groups were created based on specific characteristics, such as education, gender, or race. A semi-structured interview format asked questions about personal, environmental, and policy-related factors influencing employment after SCI. Groups were recorded, transcribed, and entered into NVivo before coding by 2 reviewers. Results: Within the area of behaviors and management of physical health and functioning, 4 overlapping themes were identified: (1) relearning your own body and what it can do; (2) general health and wellness behaviors; (3) communication, education, and advocacy; and (4) secondary conditions and aging. Specific themes articulate the many types of behaviors individuals must master and their impact on return to work as well as on finding, maintaining, and deciding to leave employment. Conclusions: Individuals with SCI who are successfully employed after injury must learn how to perform necessary behaviors to manage health and function in a work environment. The decision to leave employment often appears to be associated with secondary complications and other conditions that occur as persons with SCI age.

Publishing datasets with eSciDoc and panMetaDocs
Ulbricht, D.; Klump, J.; Bertelmann, R.
2012-04-01
Currently serveral research institutions worldwide undertake considerable efforts to have their scientific datasets published and to syndicate them to data portals as extensively described objects identified by a persistent identifier. This is done to foster the reuse of data, to make scientific work more transparent, and to create a citable entity that can be referenced unambigously in written publications. GFZ Potsdam established a publishing workflow for file based research datasets. Key software components are an eSciDoc infrastructure [1] and multiple instances of the data curation tool panMetaDocs [2]. The eSciDoc repository holds data objects and their associated metadata in container objects, called eSciDoc items. A key metadata element in this context is the publication status of the referenced data set. PanMetaDocs, which is based on PanMetaWorks [3], is a PHP based web application that allows to describe data with any XML-based metadata schema. The metadata fields can be filled with static or dynamic content to reduce the number of fields that require manual entries to a minimum and make use of contextual information in a project setting. Access rights can be applied to set visibility of datasets to other project members and allow collaboration on and notifying about datasets (RSS) and interaction with the internal messaging system, that was inherited from panMetaWorks. When a dataset is to be published, panMetaDocs allows to change the publication status of the eSciDoc item from status "private" to "submitted" and prepare the dataset for verification by an external reviewer. After quality checks, the item publication status can be changed to "published". This makes the data and metadata available through the internet worldwide. PanMetaDocs is developed as an eSciDoc application. It is an easy to use graphical user interface to eSciDoc items, their data and metadata. It is also an application supporting a DOI publication agent during the process of

L’homme et la bête : chiens et politique dans Les Mohicans de Paris
Directory of Open Access Journals (Sweden)
Nicolas Gauthier
2015-12-01
Full Text Available Cet article étudie comment le recours à l’animalisation dans Les Mohicans de Paris d’Alexandre Dumas est l’espace d’une véritable réflexion sur les rapports entre l’humain et l’animal. Ceci apparaît de façon nette dans la fictionnalisation du chien qui induit un brouillage des limites séparant humain et animal, brouillage qui a pour fonction de permettre l’articulation des personnages canins aux enjeux fondamentaux du roman. De façon plus précise, la mise en scène du « meilleur ami de l’homme » sert à redoubler le projet politique au cœur des Mohicans de Paris. This paper examines how, in Les Mohicans de Paris, Alexandre Dumas assigns animalistic features to some characters to question the relations between humans and animals while portraying the various dogs in the novel in a way which blurs the limits between humans and animals. These seemingly accessory canine characters are actually closely associated with the fundamental elements of the novel. More precisely, the way “man’s best friend” is put in fiction actually repeats the political project at the heart of Les Mohicans de Paris.

Pediatric SCI/D caregiver mental health and family dynamics in Colombia, South America.
Doyle, Sarah T; Perrin, Paul B; Nicholls, Elizabeth; Olivera, Silvia Leonor; Quintero, Lorena Medina; Otálvaro, Nadezda Yulieth Méndez; Arango-Lasprilla, Juan Carlos

This study examined the connections between family dynamics and the mental health of caregivers of youth with spinal cord injuries/disorders (SCI/D) caregivers from Colombia, South America. It was hypothesized that lower family functioning would be associated with poorer caregiver mental health. A cross-sectional study of self-report data collected from caregivers through the Hospital Universatario Hernando Moncaleano Perdomo in Neiva, Colombia. Thirty caregivers of children with SCI/D from Nevia, Colombia who were a primary caregiver for ≥3 months, providing care for an individual who was ≥6 months post-injury/diagnosis, familiar with the patient's history, and without neurological or psychiatric conditions. Caregivers' average age was 41.30 years (SD = 10.98), and 90% were female. Caregivers completed Spanish versions of instruments assessing their own mental health and family dynamics. Family dynamics explained 43.2% of the variance in caregiver burden and 50.1% of the variance in satisfaction with life, although family dynamics were not significantly associated with caregiver depression in the overall analysis. Family satisfaction was the only family dynamics variable to yield a significant unique association with any index of caregiver mental health (satisfaction with life). If similar findings emerge in future intervention research, interventions for pediatric SCI/D caregivers in Colombia and other similar global regions could benefit from including techniques to improve family dynamics, especially family satisfaction, given the strong potentially reciprocal connection between these dynamics and caregiver mental health. The degree of disability resulting from SCI/D can vary greatly depending on the severity and level of the lesion, though permanent impairment is often present that profoundly impacts both physical and psychological functioning. Very little is known about the impact of pediatric SCI/D in developing countries, despite the high rates of

Effect of the Gouy phase on the coherent phase control of chemical reactions.
Gordon, Robert J; Barge, Vishal J
2007-11-28
We show how the spatial phase of a focused laser beam may be used as a tool for controlling the branching ratio of a chemical reaction. Guoy discovered [Acad. Sci., Paris, C. R. 110, 1250 (1890)] that when an electromagnetic wave passes through a focus its phase increases by pi. In a coherent control scheme involving the absorption of n photons of frequency omega(m) and m photons of frequency omega(n), the overall phase shift produced by the Gouy phase is (n-m)pi. At any given point in space, this phase shift is identical for all reaction products. Nevertheless, if the yields for different reaction channels have different intensity dependencies, the Gouy phase produces a net phase lag between the products that varies with the axial coordinate of the laser focus. We obtain here analytical and numerical values of this phase as the laser focus is scanned across the diameter of the molecular beam, taking into account the Rayleigh range and astigmatism of the laser beam and saturation of the transition. We also show that the modulation depth of the interference pattern may be increased by optimizing the relative intensities of the two fields.

We study universal critical adsorption on a solid sphere and a solid cylinder in a fluid at bulk criticality, where preferential adsorption occurs. We use a local functional theory proposed by Fisher et al. [M. E. Fisher and P. G. de Gennes, C. R. Acad. Sci. Paris Ser. B 287, 207 (1978); M. E. Fisher and H. Au-Yang, Physica A 101, 255 (1980), 10.1016/0378-4371(80)90112-0]. We calculate the mean order parameter profile ψ (r ) , where r is the distance from the sphere center and the cylinder axis, respectively. The resultant differential equation for ψ (r ) is solved exactly around a sphere and numerically around a cylinder. A strong adsorption regime is realized except for very small surface field h1, where the surface order parameter ψ (a ) is determined by h1 and is independent of the radius a . If r considerably exceeds a , ψ (r ) decays as r-(1 +η ) for a sphere and r-(1 +η )/2 for a cylinder in three dimensions, where η is the critical exponent in the order parameter correlation at bulk criticality.

Vincenzo Neri and His Legacy in Paris and Bologna.
Vanone, Federico; Lorusso, Lorenzo; Venturini, Simone
2016-01-01
Italian neurologist Vincenzo Neri was able to discover cinematography at the beginning of his career, when in 1908 he went to Paris to learn and improve his clinical background by following neurological cases at La Pitié with Joseph Babinski, who became his teacher and friend. While in Paris, Neri photographed and filmed several patients of famous neurologists, such as Babinski and Pierre Marie. His stills were published in several important French neurological journals and medical texts. He also collaborated with Georges Mendel, who helped Doyen film the first known surgical operation in the history of cinema. In 1910, when he came back to Bologna, he continued in his clinical activities and, for 50 years, slowly developed a huge archive of films, images, and prints of neurological, psychiatric, and orthopedic cases. This archive was extremely helpful to Neri, who especially needed to analyze neurological disorders and to differentiate them from functional conditions in order to understand clinical signs, rules, and mechanisms.

MicroRNA-146a Contributes to SCI Recovery via Regulating TRAF6 and IRAK1 Expression.
Wei, Jinsong; Wang, Jiafeng; Zhou, Yulan; Yan, Shouquan; Li, Keshen; Lin, Hongsheng
2016-01-01
MicroRNA-146a participates in spinal cord injury (SCI) recovery. Until recently, how miRNA-146a participates in SCI remained unclear. In this study, we tried to explore the roles of miRNA-146a in the recovery of SCI using a rat model. The expression of the probable target genes of miRNA-146a (including IRAK1 and TARF6) as well as proinflammation cytokines were measured until 7 days after surgery in the three groups (sham group, SCI group, and miRNA-146a antagomir injection group). Also, the animals' motivations were estimated using Basso Beattie Bresnahan (BBB) during the whole experiment. A luciferase assay was performed to demonstrate that miRNA-146a could directly target the mRNAs of IRAK1 and TRAF6 . Our experiments indicate that miRNA-146a inhibits proinflammatory cytokine secretion by suppressing IRAK1 and TRAF6 expression in the SCI model. In contrast, miRNA-146a may be upregulated by inflammatory mediators via the IRAK1 / TRAF6 pathway in the spinal cord. As a negative feedback element, miRNA-146a could make sure that the expression of IRAK1 - and TRAF6 -mediated genes was under tight control. Thus, miRNA-146a may serve as a novel therapeutic target for SCI interventions.

Neuropathic pain after spinal cord injury (SCI) is common, often intractable, and can be severely debilitating. A number of mechanisms have been proposed for this pain, which are discussed briefly, along with methods for revealing SCI pain in animal models, such as the recently applied conditioned place preference test. During the last decade, studies of animal models have shown that both central neuroinflammation and behavioral hypersensitivity (indirect reflex measures of pain) persist chronically after SCI. Interventions that reduce neuroinflammation have been found to ameliorate pain-related behavior, such as treatment with agents that inhibit the activation states of microglia and/or astroglia (including IL-10, minocycline, etanercept, propentofylline, ibudilast, licofelone, SP600125, carbenoxolone). Reversal of pain-related behavior has also been shown with disruption by an inhibitor (CR8) and/or genetic deletion of cell cycle-related proteins, deletion of a truncated receptor (trkB.T1) for brain-derived neurotrophic factor (BDNF), or reduction by antisense knockdown or an inhibitor (AMG9810) of the activity of channels (TRPV1 or Nav1.8) important for electrical activity in primary nociceptors. Nociceptor activity is known to drive central neuroinflammation in peripheral injury models, and nociceptors appear to be an integral component of host defense. Thus, emerging results suggest that spinal and systemic effects of SCI can activate nociceptor-mediated host defense responses that interact via neuroinflammatory signaling with complex central consequences of SCI to drive chronic pain. This broader view of SCI-induced neuroinflammation suggests new targets, and additional complications, for efforts to develop effective treatments for neuropathic SCI pain.

To use valid subjective reports sensible to cognitive decline is vital to identify very early signs of dementia development. Use of everyday technology (ET) has been shown to be sensitive to differentiate adults with mild cognitive impairment (MCI) from controls, but the group with subjective cognitive impairment (SCI) has not yet been examined. This study aims to investigate and compare self-perceived ability in ET use and number of ETs reported as actually used in a sample of older adults with SCI, MCI, and older adults with no known cognitive impairment, i.e. Older adults with MCI (n = 29), SCI ( n = 26), and controls (n = 30) were interviewed with the short version of the Everyday Technology Use Questionnaire (S-ETUQ) to capture self-perceived ability in ET use and number of ETs used. To generate individual measures of ability to use ET, Rasch analysis was used. The measures were then compared group-wise using ANCOVA. The numbers of ETs used were compared group-wise with ANOVA. Controls versus SCI and MCI differed significantly regarding ETs reported as used, but not SCI versus MCI. Similarly, in ability to use ET, controls versus SCI and MCI differed significantly but not SCI versus MCI. The significantly lower numbers of ETs reported as actually used and the lower ability in SCI and MCI groups compared to controls suggest that ET use is affected already in very minor cognitive decline. This indicates that self-reported ET use based on the S-ETUQ is sensitive to detect changes already in SCI.

[From traditional to modern hospital--from Paris to Berlin].
Murken, Axel Hinrich
Discussions about the modernisation and reform of the Hôtel Dieu in Paris concerning the catastrophic fire of 1772 there were followed very closely in Prussia and other German countries, though for a long time this had only slight consequences for modernising developments in the hospitals of Berlin or other administrative capitals of Germany. In contrast to this, the Hôpital Lariboisière was praised as a model example in Germany soon after its completion in 1854 after the pre-revolutionary Parisian plans, was imitated in Berlin twenty years later. It must be added that in Prussia great importance was attached to stricter requirements for hygiene and ventilation than in Paris. This was clearly demonstrated barely in the construction of the pavilionhospital in Berlin-Friedrichshain (1868-1874) with an extremely decentralized layout. It was not until two generations later with the completion of the municipal hospital Westend in Charlottenburg (1904-1907), a suburb of Berlin, that a slightly modified "Lariboisière" in the Wilheminian brick Baroque style was built. Similarily the acceptance of high-rise construction was, compared with Paris, considerably delayed on the German hospital scene. Whereas in the USA and France plans had been made for high-rise hospitals from the 1920s on and realized by 1935, as with the Hôpital Beaujon in Paris (1932-1935), there were fundamental reservations about them in Germany. As a result, this conception of the structure, with an effective concentration of inpatient care in towers together with separate low-rise buildings for functions such as treatment and diagnosis, only gradually gained acceptance in Germany at the end of the 1960s. On the other hand, German architects such as Hermann Distel (1875-1946) or Ernst Kopp (1890-1962), had already, indeed before the Second World War, promoted the high-rise type for inpatient care on theoretical grounds. In addition, two hospitals providing medical care within in Berlin, Martin

The Paris meteorite is one of the most primitive carbonaceous chondrites. It is reported to be the least aqueously altered CM chondrite, and to have experienced only weak thermal metamorphism. We have analyzed for the first time the amino acid and hydrocarbon contents of this pristine meteorite by gas chromatography-mass spectrometry (GC-MS). When plotting the relative amino acids abundances of several CM chondrites according to the increasing hydrothermal scale (petrologic subtypes), from the CM2.7/2.8 Paris to the CM2.0 MET 01070, Paris has the lowest relative abundance of β-alanine/glycine (0.15), which fits with the relative abundances of β-alanine/glycine increasing with increasing aqueous alteration for CM chondrites. These results confirm the influence of aqueous alteration on the amino acid abundances and distribution. The amino acid analysis shows that the isovaline detected in this meteorite is racemic (D/L = 0.99 ± 0.08; L-enantiomer excess = 0.35 ± 0.5%; corrected D/L = 1.03; corrected L-enantiomer excess = -1.4 ± 2.6%). The identified hydrocarbons show that Paris has n-alkanes ranging from C16 to C25 and 3- to 5-ring nonalkylated polycyclic aromatic hydrocarbons (PAHs). The lack of alkylated PAHs in Paris seems to be also related to this low degree of aqueous alteration on its parent body. The extraterrestrial hydrocarbon content, suggested by the absence of any biomarker, may well have a presolar origin. The chemistry of the Paris meteorite may thus be closely related to the early stages of the solar nebula with a contribution from interstellar (molecular cloud) precursors.

Although the adult spinal cord contains a population of multipotent neural stem/precursor cells (NSPCs) exhibiting the potential to replace neurons, endogenous neurogenesis is very limited after spinal cord injury (SCI) because the activated NSPCs primarily differentiate into astrocytes rather than neurons. Valproic acid (VPA), a histone deacetylase inhibitor, exerts multiple pharmacological effects including fate regulation of stem cells. In this study, we cultured adult spinal NSPCs from chronic compressive SCI rats and treated with VPA. In spite of inhibiting the proliferation and arresting in the G0/G1 phase of NSPCs, VPA markedly promoted neuronal differentiation (β-tubulin III(+) cells) as well as decreased astrocytic differentiation (GFAP(+) cells). Cell cycle regulator p21(Cip/WAF1) and proneural genes Ngn2 and NeuroD1 were increased in the two processes respectively. In vivo, to minimize the possible inhibitory effects of VPA to the proliferation of NSPCs as well as avoid other neuroprotections of VPA in acute phase of SCI, we carried out a delayed intraperitoneal injection of VPA (150 mg/kg/12 h) to SCI rats from day 15 to day 22 after injury. Both of the newborn neuron marker doublecortin and the mature neuron marker neuron-specific nuclear protein were significantly enhanced after VPA treatment in the epicenter and adjacent segments of the injured spinal cord. Although the impaired corticospinal tracks had not significantly improved, Basso-Beattie-Bresnahan scores in VPA treatment group were better than control. Our study provide the first evidence that administration of VPA enhances the neurogenic potential of NSPCs after SCI and reveal the therapeutic value of delayed treatment of VPA to SCI.

2016-10-01
Full Text Available The article investigates the common and distinctive features of the terrorist attacks in Paris and Brussels in 2015 and 2016. The attacks have confirmed the weakness of European security system in the context of the protection of its citizens from the threat № 1 in the world. The high level of democracy and liberalism are not allowed to use power instruments effectively in the fight against terrorism, which was the result of the fact that the terrorists were able to freely access to the place of their acts and to implement them. It was determined that the common features are the following: in Paris and in Brussels, the attacks were carried out by terrorist militaristic group «The Islamic State of Iraq and the Levant» (ISIL; the places of commission of terrorist acts; guns of terrorists; military units of France and Belgium are parties of the armed conflict in Syria on the side of the Syrian opposition and struggle against ISIL; there were a few terrorist attacks. It is proved that the differences are as follows: in Paris, in addition to explosives, packed with nails, also were used automatic weapons and grenades, but only explosives in Brussels; France is more active in the fight against terrorism in the international arena and in every way opposed to violence against humanity, so there is a terrorist attack can be seen as a blow to the democratic and humanitarian values; Belgium is a «political heart» of the European Union that’s why the terrorist attack on it can be seen as a blow to the political system of the EU; in Paris, the attack was supposed to apply except for the population and for high officials in the name of F. Hollande and F. Steinmeier, and in Brussels – only civilians.conducting effective public diplomacy by means of virtual diplomacy.

Sources and geographical origins of fine aerosols in Paris (France)
International Nuclear Information System (INIS)
Bressi, M.; Nicolas, J.B.; Sciare, J.; Feron, A.; Nonnaire, N.; Petit, J.E.
2014-01-01
The present study aims at identifying and apportioning fine aerosols to their major sources in Paris (France) - the second most populated - larger urban zone - in Europe - and determining their geographical origins. It is based on the daily chemical composition of PM2.5 examined over 1 year at an urban background site of Paris (Bressi et al., 2013). Positive matrix factorization (EPA PMF3.0) was used to identify and apportion fine aerosols to their sources; bootstrapping was performed to determine the adequate number of PMF factors, and statistics (root mean square error, coefficient of determination, etc.) were examined to better model PM2.5 mass and chemical components. Potential source contribution function (PSCF) and conditional probability function (CPF) allowed the geographical origins of the sources to be assessed; special attention was paid to implement suitable weighting functions. Seven factors, namely ammonium sulfate (A.S.)-rich factor, ammonium nitrate (A.N.)-rich factor, heavy oil combustion, road traffic, biomass burning, marine aerosols and metal industry, were identified; a detailed discussion of their chemical characteristics is reported. They contribute 27, 24, 17, 14, 12, 6 and 1% of PM2.5 mass (14.7 μgm -3 ) respectively on the annual average; their seasonal variability is discussed. The A.S.- and A.N.-rich factors have undergone mid- or long-range transport from continental Europe; heavy oil combustion mainly stems from northern France and the English Channel, whereas road traffic and biomass burning are primarily locally emitted. Therefore, on average more than half of PM2.5 mass measured in the city of Paris is due to mid- or long-range transport of secondary aerosols stemming from continental Europe, whereas local sources only contribute a quarter of the annual averaged mass. These results imply that fine-aerosol abatement policies conducted at the local scale may not be sufficient to notably reduce PM2.5 levels at urban background sites

Computing Beyond the Church-Turing Limit
Jones, Robert
2009-05-01
Dershowitz and Gurevich claim to have proven the Church-Turing theorem starting from a set of 4 reasonable postulates. (Bulletin of Symbolic Logic, vol. 14, num. 3, Sept. 2008, pg. 299) But their postulate II assumes fixed vocabulary. Humans, however, change their vocabulary words (and concepts) over time. My Asa H artificial intelligence also changes its vocabulary. (Trans. of the Kansas Acad. of Sci., vol. 109, no. 3/4, pg 159, 2006, www.bioone.org/archive/0022- 8443/109/3/pdf/i0022-8443-109-3-159.pdf) Their postulate I excludes nondeterministic transitions between states. I don't know how often humans flip a coin but my Asa H does employ random transitions under certain circumstances. Perhaps humans and Asa H go beyond the Church-Turing limit. (Trans. Kansas Acad. of Sci., 108, 3/4, pg. 169, 2005)

Clinical practice guidelines. To develop the first Canadian clinical practice guidelines for screening and diagnosis of neuropathic pain in people with spinal cord injury (SCI). The guidelines are relevant for inpatient and outpatient SCI rehabilitation settings in Canada. The CanPainSCI Working Group reviewed evidence to address clinical questions regarding screening and diagnosis of neuropathic pain after SCI. A consensus process was followed to achieve agreement on recommendations and clinical considerations. Twelve recommendations, based on expert consensus, were developed for the screening and diagnosis of neuropathic pain after SCI. The recommendations address methods for assessment, documentation tools, team member accountability, frequency of screening and considerations for diagnostic investigation. Important clinical considerations accompany each recommendation. The expert Working Group developed recommendations for the screening and diagnosis of neuropathic pain after SCI that should be used to inform practice.

Communication is powerful predictor of health-related quality of life and overall well-being, yet its role in promoting rehabilitation outcomes in spinal cord injury (SCI) is rarely mentioned. This article systematically analyzes and synthesizes literature from multiple disciplines according to a biopsychosocial perspective, providing an evidence base for clinical practice and clear direction for future research. Systematic literature review and analysis, incorporating mapping to International Classification of Functioning, Disability and Health (ICF) codes. In total 4338 entries were retrieved from CINAHL, PsychInfo, Medline, PubMed and SpeechBite databases for the period 1990-2014. A total of 115 treatment and observational studies (quantitative and qualitative) detailed aspects of communication according to structure, function, activity, participation and environmental factors; evident of the complex interactions between communicative function with daily living after SCI. Communication is a relative strength in SCI, key to empowerment, independence, social interaction, and well-being, yet its potential to enhance SCI rehabilitation outcomes remains largely underexplored and untapped. Through elucidating interactions between communication and functioning, the adapted ICF framework affords clinicians and researchers insight into areas of intervention most likely to result in widespread gains. Conscious consideration should be given to the role of communication, within an integrative, strengths-based, multidisciplinary approach to clinical practice and future research. Implications for Rehabilitation Communication fosters empowerment, independence and greater participation in life roles; recognized as a powerful predictor of health-related quality of life and overall well-being. The ICF framework elucidates influences to communicative function, and components which are influenced by communication, providing valuable insight for clinicians and researchers

Environmental magnetism and magnetic mapping of urban metallic pollution (Paris, France)
Isambert, Aude; Franke, Christine; Macouin, Mélina; Rousse, Sonia; Philip, Aurélio; de Villeneuve, Sybille Henry

Airborne pollution in dense urban areas is nowadays a subject of major concern. Fine particulate pollution events are ever more frequent and represent not only an environmental and health but also a real economic issue. In urban atmosphere, the so-called PM2.5 (particulate matter pollution and determine their sources (Sagnotti et al., 2012). In this study, we report on magnetic measurements of traffic-related airborne PM in the city of Paris, France. Two distinct environments were sampled and analyzed along the Seine River: the aquatic environment in studying fluvial bank and river bed sediments and the atmospheric environment by regarding magnetic particles trapped in adjacent tree barks (Platanus hispanica). About 50 sediment samples and 350 bark samples have been collected and analysed to determine their magnetic properties (susceptibility, hysteresis parameters, IRM, frequency-dependent susceptibility) and to estimate the presence and spatial concentration of superparamagnetic or multi-domain particles for each sample type. The bark results allow proposing a high spatial resolution mapping (pollution. In addition to that, the sampling of banks and riverbed sediments of the Seine allow a global estimation on the anthropogenic versus detrital and biologic input in the city of Paris. The first results presented here show a general increase of the concentration in magnetic particles from upstream to downstream Paris probably linked to urban pollutions as previously observed for suspended particulate matter (Franke et al. 2009; Kayvantash, 2016).

Earlier this week I was in Paris to join particle physicists from around the world at the International Conference on High-Energy Physics, ICHEP 2010. This conference series began in 1950 as the ‘Rochester series’, named for the original venue in the US, and its meetings rapidly became the place to present the latest results and discoveries. Particle physics has certainly come a long way since those early days. In 60 years, the meetings have witnessed the birth and growth of CERN, the development of the current Standard Model of particles and their interactions - and now the first results from a truly international project, the LHC. I’d had the opportunity to be present at some of the previous meetings where important discoveries were announced, but this was the first time I had the privilege to attend as the Director-General of the laboratory that was the focus of much of the attention.

Different geographical origins and species of Paris obtained from southwestern China were discriminated by near infrared (NIR) spectroscopy and high performance liquid chromatography (HPLC) combined with multivariate analysis. The NIR parameter settings were scanning (64 times), resolution (4 cm−1), scanning range (10000 cm−1∼4000 cm−1) and parallel collection (3 times). NIR spectrum was optimized by TQ 8.6 software, and the ranges 7455∼6852 cm−1 and 5973∼4007 cm−1 were selected according to the spectrum standard deviation. The contents of polyphyllin I, polyphyllin II, polyphyllin VI, and polyphyllin VII and total steroid saponins were detected by HPLC. The contents of chemical components data matrix and spectrum data matrix were integrated and analyzed by partial least squares discriminant analysis (PLS-DA). From the PLS-DA model of NIR spectrum, Paris samples were separated into three groups according to the different geographical origins. The R2X and Q2Y described accumulative contribution rates were 99.50% and 94.03% of the total variance, respectively. The PLS-DA model according to 12 species of Paris described 99.62% of the variation in X and predicted 95.23% in Y. The results of the contents of chemical components described differences among collections quantitatively. A multivariate statistical model of PLS-DA showed geographical origins of Paris had a much greater influence on Paris compared with species. NIR and HPLC combined with multivariate analysis could discriminate different geographical origins and different species. The quality of Paris showed regional dependence. PMID:24558477

To grasp the international developing tendency of acupuncture research and provide some references for promoting acupuncture and moxibustion internationalization process, the articles about acupuncture in Science Citation Index (SCI) periodicals in 2007 were retrieved by adopting the retrieval tactics on line in combination with database searching. Results indicate that 257 articles about acupuncture had been retrived from the SCI Web databases. These articles were published in 125 journals respectively, most of which were Euramerican journals. Among these journals, the impact factor of the Journal of the American Medical Association (JAMA), 25. 547, is the highest one. It is shown that the impact factors of the SCI periodicals, in which acupuncture articles embodied are increased, the quality of these articles are improved obviously and the types of the articles are various in 2007, but there is obvious difference in the results of these studies due to the difference of experimental methods, the subjects of these experiments and acupuncture manipulations. Therefore, standardization of many problems arising from the researches on acupuncture is extremely imminent.

The Frontier Speaks Back: Two Australian Artists Working in Paris and London
Directory of Open Access Journals (Sweden)
Catherine Margaret Speck

Full Text Available Australian artists living and working in Paris and London in the Belle Époque and modern eras had a deep engagement with cosmopolitanism in cities that were at the frontiers of international modernism. They experienced the liberation of putting aside issues of nation, and of working in large, alienating but culturally challenging multi-nation environs in the pre and post war years. This paper will explore how two women artists, Hilda Rix in Paris, a hub of internationalism; and Nora Heysen in London, a city ill-described in the Empire language of ‘home’ for Australians, connected with and articulated cosmopolitan culture. Expatriatism facilitated an offshore variant of Australian modernism.

Does the CDC Definition of Fever Accurately Predict Inflammation and Infection in Persons With SCI?
Trbovich, Michelle; Li, Carol; Lee, Shuko
2016-01-01
Background: Pneumonia and septicemia have the greatest impact on reduced life expectancy in persons with spinal cord injury (SCI). Fever is often the first presenting symptom of infection or inflammation. Thermoregulatory dysfunction in persons with SCI may preclude a typical febrile response to infection or inflammation and thus delay diagnostic workup. Objective: To determine the core temperature of persons with SCI in the setting of infection or inflammation and the frequency with which it meets criteria for the CDC definition of fever (>100.4°F). Methods: Retrospective review of hospitalized SCI patients over 5 years with a diagnosis of infection or inflammation (DI), defined by serum leukocytosis. In this study, 458 persons with paraplegia (PP) and 483 persons with tetraplegia (TP) had 4,191 DI episodes. Aural temperatures (T au ) on the day of DI, 7 days prior, and 14 days afterwards were abstracted from medical records. Main outcome measures were average T au at DI, frequency of temperatures >100.4°F at DI, and average baseline temperatures before and after DI. Results: Average T au at DI was 98.2°F (±1.5) and 98.2°F (±1.4) in the TP and PP groups, respectively, with only 11.6% to 14% of DI resulting in T au >100.4°F. Baseline temperatures ranged from 97.9°F (±0.7) to 98.0°F (±0.8). Conclusion: SCI persons with leukocytosis infrequently mount a fever as defined by the CDC, and baseline temperatures were subnormal (100.4°F is not a sensitive predictor of infection or inflammation in persons with SCI. Clinicians should be vigilant for alternative symptoms of infection and inflammation in these patients, so diagnostic workup is not delayed.

SCI Hospital in Home Program: Bringing Hospital Care Home for Veterans With Spinal Cord Injury.
Madaris, Linda L; Onyebueke, Mirian; Liebman, Janet; Martin, Allyson
2016-01-01
The complex nature of spinal cord injury (SCI) and the level of care required for health maintenance frequently result in repeated hospital admissions for recurrent medical complications. Prolonged hospitalizations of persons with SCI have been linked to the increased risk of hospital-acquired infections and development or worsening pressure ulcers. An evidence-based alternative for providing hospital-level care to patients with specific diagnoses who are willing to receive that level of care in the comfort of their home is being implemented in a Department of Veterans Affairs SCI Home Care Program. The SCI Hospital in Home (HiH) model is similar to a patient-centered interdisciplinary care model that was first introduced in Europe and later tested as part of a National Demonstration and Evaluation Study through Johns Hopkins School of Medicine and School of Public Health. This was funded by the John A. Hartford Foundation and the Department of Veterans Affairs. The objectives of the program are to support veterans' choice and access to patient-centered care, reduce the reliance on inpatient medical care, allow for early discharge, and decrease medical costs. Veterans with SCI who are admitted to the HiH program receive daily oversight by a physician, daily visits by a registered nurse, access to laboratory services, oxygen, intravenous medications, and nursing care in the home setting. In this model, patients may typically access HiH services either as an "early discharge" from the hospital or as a direct admit to the program from the emergency department or SCI clinic. Similar programs providing acute hospital-equivalent care in the home have been previously implemented and are successfully demonstrating decreased length of stay, improved patient access, and increased patient satisfaction.

Hayabusa2 is a sample return mission of JAXA launched on 3 December 2014. Hayabusa2 is the successor of Hayabusa, which returned samples from the asteroid Itokawa to the Earth. Although the design of Hayabusa2 follows that of Hayabusa, the former is equipped with some new components. The small carry-on impactor (SCI) is one of those components. The SCI is a compact kinetic impactor designed to remove the asteroid surface regolith locally and create an artificial crater. One of the most important scientific objectives of Hayabusa2 is to investigate the chemical and physical properties of the internal materials and structures of the target body, asteroid Ryugu. Hayabusa2 will attempt to observe the resultant crater with some scientific instruments and to get samples from around the crater. High kinetic energy is required to create a meaningful crater, however, the impact system design needs to fit within strict constraints. Complicated functions, such as a guidance and control system, are not permitted. A special type of shaped charge is used for the acceleration of the impactor of the SCI in order to make system simpler. Using this explosion technique makes it possible to accelerate the impactor very quickly and to hit the asteroid without a guidance system. However, the impact operation will be complicated because the explosive is very powerful and it scatters high-speed debris at the detonation. This paper describes an overview of the SCI system, the results of the development testing and an outline of the impact experiment of the Hayabusa2 mission.

Hydrocarbon pollution fixed to combined sewer sediment: a case study in Paris.
Rocher, Vincent; Garnaud, Stéphane; Moilleron, Régis; Chebbo, Ghassan
2004-02-01
Over a period of two years (2000-2001), sediment samples were extracted from 40 silt traps (STs) spread through the combined sewer system of Paris. All sediment samples were analysed for physico-chemical parameters (pH, organic matter content, grain size distribution), with total hydrocarbons (THs) and 16 polycyclic aromatic hydrocarbons (PAHs) selected from the priority list of the US-EPA. The two main objectives of the study were (1) to determine the hydrocarbon contamination levels in the sediments of the Paris combined sewer system and (2) to investigate the PAH fingerprints in order to assess their spatial variability and to elucidate the PAH origins. The results show that there is some important inter-site and intra-site variations in hydrocarbon contents. Despite this variability, TH and PAH contamination levels (50th percentile) in the Parisian sewer sediment are estimated at 530 and 18 microg g(-1), respectively. The investigation of the aromatic compound distributions in all of the 40 STs has underlined that there is, at the Paris sewer system scale, a homogeneous PAH background pollution. Moreover, the study of the PAH fingerprints, using specific ratios, suggests the predominance of a pyrolytic origin for those PAHs fixed to the sewer sediment.

The terrorist attacks (fusillades and suicide attacks) in Paris on 13 November 2015 have had a major psychic impact on all individuals directly or secondarily exposed to them. Medico-psychological unit (CUMP) of the Paris Île-de-France region's immediate care services were immediately mobilized and rapidly strengthened by all regional medico-psychological units (CUMP) throughout the country. Psychological assistance has been provided in several key points of Paris and specifically in the 11th district City Hall of Paris where Lyon's Medico-psychological unit was located. These specific immediate psychological assistances, referred to as a "defusing process" by the medico-psychological unit (CUMP), are mostly devoted to provide the victims with an entry point to a psychological healthcare relationship and give them a first sense of soothing and relief even though they do not prevent further psychological care follow up for the victims. Nonetheless, the potential therapeutic effect of this "defusing process" has not yet been sufficiently established nor demonstrated by any scientific study. A phoning survey was carried out one-month post-terrorist attacks and interviewed the 129 victims who benefited from the "defusing process" conducted by Lyon's medico-psychological unit (CUMP) in order to collect data and assess its effects. These people, whether directly exposed, bereaved relatives or witnesses, whose average age is 35, are mostly living in the Île-de-France region. Most of them present a high score on the IES-R scale, whether they were directly exposed, bereaved relatives or witnesses. Almost all of them (96.5%) experienced at least one medical care contact within this one-month post-trauma period with psychotropic medication for 37% of them. Regarding the defusing conducted by Lyon's medico-psychological unit (CUMP) in the 11th district City Hall of Paris, it appears that 93% of the victims who were looked after indicated that they were satisfied and 87.4% of

2008-12-01
Full Text Available Amb el desenvolupament de les tecnologies de la informació i la comunicació (TIC, el plagi esdevé un problema cada cop més greu en la comunitat acadèmica. Segons els estudis sobre el plagi acadèmic elaborats en universitats de quatre països europeus diferents, l'índex de plagi entre els estudiants és considerablement alt i els estudiants majoritàriament passen per alt o permeten el plagi per la manca de coneixement, la manca de conseqüències o simplement perquè les TIC fan que el plagi sigui fàcil de cometre. Les conclusions dels estudis que es presenten en aquest article indiquen que cal introduir polítiques estrictes contra el plagi a les universitats. Pensem que s'hauria de captar l'atenció del públic sobre el problema del plagi, que s'hauria de debatre en altes esferes i que s'haurien d'aplicar mesures efectives contra el plagi. L'abast del plagi entre estudiants i les seves actituds envers el plagi reben influències de l'entorn cultural i també per l'escenari acadèmic. En comunitats multiculturals, com ara la comunitat europea, és necessari investigar i comparar el comportament acadèmic a diferents països per a establir estàndards equivalents en l'ensenyament arreu d'Europa.

El papel de la procrastinación académica como factor de la deserción universitaria
Directory of Open Access Journals (Sweden)
Angélica Garzón Umerenkova
2017-01-01
Full Text Available Se presenta una revisión teórica sobre las tendencias en el estudio de la procrastinación académica y lo que estas pueden ofrecer a la comprensión de la deserción universitaria. La procrastinación es aplazar aquello que debe ser hecho y está asociado con un fallo auto-regulatorio en el comportamiento de la gestión del tiempo. Inicialmente, se define qué es la deserción universitaria, las variables y modelos teóricos de los que se ha partido para su explicación y se presentan las principales cifras sobre deserción y cobertura universitarias. Posteriormente, se presentan los modelos de autorregulación académica desde los cuales se ha abordado el estudio de la procrastinación y, finalmente, se definen los principales hallazgos y perspectivas de intervención sobre la procrastinación. Para fomentar el aumento de la retención, es conveniente, además del estudio de las variables tradicionales asociadas a la deserción universitaria, incorporar nuevas variables que aporten elementos conceptuales a la explicación y prevención del fenómeno. Este es el caso de la procrastinación académica. Se muestra en este documento que hay evidencias de la asociación entre alta procrastinación y bajo rendimiento académico de los estudiantes, que es una competencia que se puede evaluar en los procesos de entrada a la universidad, que es posible entrenarla con éxito y que su mejora, abordada dentro del contexto del aprendizaje autorregulado, acarrea no sólo beneficios académicos sino que también ayuda a mejorar la calidad de vida de los estudiantes.

Dr. José Félix Patiño como Presidente de la Academia Nacional de Medicina.
Señores Académicos, señoras, señores:
(Santafé de Bogotá, marzo 19 de 1998
Como un "Fenómeno del Niño" y con el ímpetu emocional de esas sagas cíclicas que nos recordara
vívidamente "Cien Años de Soledad" se repite, a los ocho años, una ceremonia en que dos de sus
actores son los mismos, sólo que con orden inverso. Esta vez un hombre salido de las filas académicas, sin otro mérito que su capacidad de reconocimiento y afecto, tiene como honroso encargo pronunciar el discurso de orden en la posesión de José Félix Patiño como Presidente de la Academia Nacional de Medicina para los dos últimos años del milenio, rodeado de una dignísima Junta Directiva y sucediendo a otro hombre de cualidades eximias, que ha dirigido uno de los cuatrienios más ilustres por
los que haya pasado la corporación.En esa otra época, 1990, fue un académico ya cargado de honores y de merecimientos quien pronunciara gallardamente el discurso de orden durante el acto de mi posesión como Presidente, en el paraninfo de la Academia Colombiana de la Lengua.
Denominador común era y sigue siendo el mutuo bagaje de una amistad ininterrumpida de más de
cuarenta años, que es el que me lleva a pronunciar estas palabras, cargadas como nunca de admiración, de respeto y de cariño.
Porque la nutrida votación que llevó al académico Patiño a salir electo con el 95% de los votos,
fenómeno casi nunca antes visto en los anales de nuestra venerable Academia, no es sino la expresión
unánime de confianza por un hombre que, ya alcanzada la "edad bíblica" --como él mismo
lo dijera en sus vivaces memorias del año pasado- conserva la chispa de su infatigable intelecto,
siempre ávido para enseñar y aprender; y mantiene la integridad física y el ánimo del cirujano de

The International Conference on High Energy Physics (ICHEP) took place from 22 to 28 July in Paris, and first results from the Large Hadron Collider experiments received top billing. More than 1,100 physicists gathered in the Palais des Congrès conference centre to attend ICHEP, the world’s premier particle physics conference, where scientists presented and discussed the latest and most intriguing results from experiments in particle physics, particle astrophysics and cosmology, innovative theoretical approaches and predictions, and concepts for future accelerators and particle detectors. The buzz about the LHC experiments caught the eye of French President Nicolas Sarkozy, who addressed the conference on Monday 26 July. President Sarkozy exhorted the particle physics community to continue its quest to understand the nature of the Universe, and stated his belief that investment in fundamental research is critical for the progress of mankind.

Full Text Available Surgical experiments with laboratory animals are necessary for medical research. These studies aim to clarify the mechanism of disease, investigate the action and efficacy of new drugs or biological markers, as well as develop and enhance new therapies and apply new techniques. Regarding the models of spinal cord injury (SCI, there are several different methods that address the handling of the animals, especially concerning the use of analgesics, antibiotics and pre- and postoperative management. The lack of uniformity and standardization among the studies does not allow the understanding of the model of SCI or the proper handling of the paraplegic animals, hampering the adequate interpretation and comparison of results. The goal of this study is to establish a standard protocol on the handling of animals subjected to experimental models of SCI.La realización de experimentos quirúrgicos con animales de laboratorio son necesarios para la investigación médica.

A sub-GeV charged-current quasi-elastic νμ cross-section on carbon at SciBooNE
International Nuclear Information System (INIS)
Walding, Joseph James
2010-01-01
Neutrino-nucleus charged-current quasi-elastic scattering is the signal interaction used by many neutrino oscillation experiments. For muon disappearance studies the signal mode is ν μ n → μp. Modern oscillation experiments, such as T2K, produce neutrino beams with peak beam energies of order a few-GeV. It is therefore vitally important to have accurate measurements of the charged-current quasi-elastic cross-section for future neutrino oscillation experiments. Neutrino-nucleus cross-sections in the few-GeV region are not well understood, with the main uncertainties coming from understanding of the neutrino beam flux and the final state interactions within nuclei. SciBooNE is a sub-GeV neutrino-nucleus cross-section experiment based at Fermilab, Batavia, USA, with the goal to measure neutrino cross-sections with precision of order 5%. SciBooNE took data from June 2007 until August 2008, in total 0.99 x 10 20 and 1.53 x 10 20 protons on target were collected in neutrino and anti-neutrino mode, respectively. In this thesis a ν μ charged-current quasi-elastic (CCQE) cross-section contained within the SciBar sub-detector is presented. A method to tag muons in SciBar was developed and three samples were isolated. An excess in backwards tracks in the one-track sample is observed. A Poisson maximum likelihood is used to extract the CCQE cross-section. The fit was applied using a basic fit parameter model, successfully used to obtain the cross-section in the SciBar-MRD matched CCQE analysis. This method was found to be insufficient in describing the data for the SciBar-contained CCQE analysis. By adding two migration parameters the cross-section was calculated to be 1.004 ± 0.031 (stat) -0.150 +0.101 (sys) x 10 -38 cm 2 /neutron, excluding backwards tracks with a χ 2 = 203.8/76 d.o.f. and 1.083 ± 0.030(stat) -0.177 +0.115 (sys) x 10 -38 cm 2 /neutron, including backwards tracks with a χ 2 = 659.8/133 d.o.f.

Understanding the origin of Paris Agreement emission uncertainties
Rogelj, Joeri; Fricko, Oliver; Meinshausen, Malte; Krey, Volker; Zilliacus, Johanna J. J.; Riahi, Keywan
2017-06-01
The UN Paris Agreement puts in place a legally binding mechanism to increase mitigation action over time. Countries put forward pledges called nationally determined contributions (NDC) whose impact is assessed in global stocktaking exercises. Subsequently, actions can then be strengthened in light of the Paris climate objective: limiting global mean temperature increase to well below 2 °C and pursuing efforts to limit it further to 1.5 °C. However, pledged actions are currently described ambiguously and this complicates the global stocktaking exercise. Here, we systematically explore possible interpretations of NDC assumptions, and show that this results in estimated emissions for 2030 ranging from 47 to 63 GtCO2e yr-1. We show that this uncertainty has critical implications for the feasibility and cost to limit warming well below 2 °C and further to 1.5 °C. Countries are currently working towards clarifying the modalities of future NDCs. We identify salient avenues to reduce the overall uncertainty by about 10 percentage points through simple, technical clarifications regarding energy accounting rules. Remaining uncertainties depend to a large extent on politically valid choices about how NDCs are expressed, and therefore raise the importance of a thorough and robust process that keeps track of where emissions are heading over time.

Health care providers (HCPs) are preferred sources of physical activity (PA) information; however, minimal research has explored HCPs' knowledge of spinal cord injury (SCI) PA guidelines, and no research has examined HCP trainees' PA guideline knowledge. The current study explored HCPs' and trainees' initial knowledge of PA guidelines for both adults with SCI and the general population, and the utility of an event-based intervention for improving this knowledge. Participants (HCPs n = 129; trainees n = 573) reported guideline knowledge for both sets of guidelines (SCI and general population) immediately after, one-month, and six-months following the intervention. Frequencies determined guideline knowledge at each timepoint, while chi-squared tests examined differences in knowledge of both guidelines, as well as knowledge differences in the short- and long-term. Results demonstrated that HCPs and trainees lack knowledge of PA guidelines, particularly guidelines for adults with SCI. The results further suggest that a single event-based intervention is not effective for improving long-term guideline knowledge. Suggestions are made for future research with the aim of improving interventions that target HCP and HCP trainees' long-term guideline knowledge for adults with SCI and the general population.

Full Text Available El objetivo del presente estudio es determinar si existe relación entre la competencia lecto-escritora de los estudiantes de primer año en una universidad privada de Bucaramanga, su desempeño académico y su permanencia durante el primer año de estudio. Se tomó una población de 350 estudiantes que ingresaron en el segundo semestre del año 2011 para participar en la investigación. Se emplearon cuestionarios y entrevistas para indagar la opinión de los estudiantes y docentes acerca de las habilidades lectoescritoras y su relación con la vida académica. Adicionalmente, se consultaron bases de datos institucionales, los puntajes de la prueba nacional SABER 11 y el puntaje obtenido en la prueba institucional de ingreso que evaluó la producción escrita de un texto argumentativo. Los resultados muestran una relación entre la competencia lecto-escritora, el desempeño académico y la tasa de deserción estudiantil, hallazgo corroborado por la mayoría de los docentes entrevistados. Sin embargo, los estudiantes desertores declaran que dicha competencia no es fundamental en el éxito académico. El estudio demuestra la necesidad de implementar acciones de acompañamiento a la población estudiantil universitaria para prevenir la deserción temprana por factores asociados al bajo rendimiento académico causado por un bajo nivel de desarrollo en la competencia lecto-escritora.

Reactions to the Paris Agreement oscillate between political enthusiasm, given the diplomatic challenge that was taken-up, and activist disappointment, considering the emergency and scale of transformations to undertake to tackle climate change. The legal analysis of the COP21, its results and prospects they open however needs to be done in the light of dispassionate criteria. The one proposed in this paper uses a global standard of transparency. The reading grid offered thus enables to locate the Paris Agreement in the context of a global and complex governance; two features that the theory of global administrative law aims to better understand, from an empirical but also a prescriptive approaches. This assessment shows that the balance between transparency and opacity, intelligibility, effectiveness or efficiency is both delicate to establish and unstable. If the way the cursor was positioned under the Paris Agreement may seem unsatisfactory in many respects, it must not be forgotten that it is intended to evolve
