  8. Bifurcated SEN with Fluid Flow Conditioners

    2014-01-01

    Full Text Available This work evaluates the performance of a novel design for a bifurcated submerged entry nozzle (SEN used for the continuous casting of steel slabs. The proposed design incorporates fluid flow conditioners attached on SEN external wall. The fluid flow conditioners impose a pseudosymmetric pattern in the upper zone of the mold by inhibiting the fluid exchange between the zones created by conditioners. The performance of the SEN with fluid flow conditioners is analyzed through numerical simulations using the CFD technique. Numerical results were validated by means of physical simulations conducted on a scaled cold water model. Numerical and physical simulations confirmed that the performance of the proposed SEN is superior to a traditional one. Fluid flow conditioners reduce the liquid free surface fluctuations and minimize the occurrence of vortexes at the free surface.

    2017-10-01

    In the frame of the Copernicus programme, ESA has developed and launched the Sentinel-2 optical imaging mission that delivers optical data products designed to feed downstream services mainly related to land monitoring, emergency management and security. The Sentinel-2 mission is the constellation of two polar orbiting satellites Sentinel-2A and Sentinel-2B, each one equipped with an optical imaging sensor MSI (Multi-Spectral Instrument). Sentinel-2A was launched on June 23rd, 2015 and Sentinel-2B followed on March 7th, 2017. With the beginning of the operational phase the constellation of both satellites enable image acquisition over the same area every 5 days or less. To use unique potential of the Sentinel-2 data for land applications and ensure the highest quality of scientific exploitation, accurate correction of satellite images for atmospheric effects is required. Therefore the atmospheric correction processor Sen2Cor was developed by Telespazio VEGA Deutschland GmbH on behalf of ESA. Sen2Cor is a Level-2A processor which main purpose is to correct single-date Sentinel-2 Level-1C Top-Of-Atmosphere (TOA) products from the effects of the atmosphere in order to deliver a Level-2A Bottom-Of-Atmosphere (BOA) reflectance product. Additional outputs are an Aerosol Optical Thickness (AOT) map, a Water Vapour (WV) map and a Scene Classification (SCL) map with Quality Indicators for cloud and snow probabilities. Telespazio France and DLR have teamed up in order to provide the calibration and validation of the Sen2Cor processor. Here we provide an overview over the Sentinel-2 data, processor and products. It presents some processing examples of Sen2Cor applied to Sentinel-2 data, provides up-to-date information about the Sen2Cor release status and recent validation results at the time of the SPIE Remote Sensing 2017.

  16. VineSens: An Eco-Smart Decision-Support Viticulture System

    Directory of Open Access Journals (Sweden)

    Josman P. Pérez-Expósito

    2017-02-01

    Full Text Available This article presents VineSens, a hardware and software platform for supporting the decision-making of the vine grower. VineSens is based on a wireless sensor network system composed by autonomous and self-powered nodes that are deployed throughout a vineyard. Such nodes include sensors that allow us to obtain detailed knowledge on different viticulture processes. Thanks to the use of epidemiological models, VineSens is able to propose a custom control plan to prevent diseases like one of the most feared by vine growers: downy mildew. VineSens generates alerts that warn farmers about the measures that have to be taken and stores the historical weather data collected from different spots of the vineyard. Such data can then be accessed through a user-friendly web-based interface that can be accessed through the Internet by using desktop or mobile devices. VineSens was deployed at the beginning in 2016 in a vineyard in the Ribeira Sacra area (Galicia, Spain and, since then, its hardware and software have been tested to prevent the development of downy mildew, showing during its first season that the system can led to substantial savings, to decrease the amount of phytosanitary products applied, and, as a consequence, to obtain a more ecologically sustainable and healthy wine.

    2016-12-01

    Due to launch of Sentinel-2 mission European Space Agency (ESA) started Sentinel-2 for Agriculture (Sen2-Agri) project coordinated by Universite catholique de Louvain (UCL). Ukraine is selected as one of 3 country level demonstration sites for benchmarking Sentinel-2 data due to wide range of main crops (both winter and summer), big fields and high enough climate variability over the territory [1-2]. Within this county level demonstration main objectives are following: i) Sentinel's products quality assessment and their suitability estimation for the territory of Ukraine [2]; ii) demonstration in order to convince decision makers and state authorities; iii) assessment of the personnel and facilities required to run the Sen2-Agri system and creation of Sen-2 Agri products (crop type maps and such essential climatic variable as Leaf Area Index - LAI [3]). During this project ground data were collected for crop land mapping and crop type classification along the roads within main agro-climatic zones of Ukraine. For LAI estimation we used indirect non-destructive method which is based on DHP-images and VALERI protocol. Products created with use of Sen2-Agri system deployed during project execution and results of neural-network approach utilization will be compared. References Kussul, N., Lemoine, G., Gallego, F.

  2. Sen and the collective choice Sen y la elección colectiva

    Directory of Open Access Journals (Sweden)

    González Jorge Ivan

    1998-12-01

    Full Text Available

    Between Arrow and Sen there are two types of rupture. The first, in coherence with the founding premises of the impossibility theorems of Arrow, shows that it is feasible to find consistent processes of collective choice, as long as one is willing to give up axiomatic "puri ty". The second places Sen on very different ground than Arrow. Sen makes explicit the goodness of  interpersonal comparisons and does not hide his sympathies for cardinal mea sures of utility and welfare. He shows that if we accept that an individual j decides taking into account the welfare he would experience in the case of finding himself in situation x of a person i, then there is no other alternative than to make explicit the criterion of justice that underlies all collective choice.

    Entre Arrow y Sen hay dos tipos de ruptura. La primera que coherente con las premisas fundantes de los teoremas de imposibilidad de Arrow, muestra que es factible encontrar procesos de eleccion colectiva consistentes, siempre y cuando se esté dispuesto a renunciar a la 'pureza' axiomatica. La segunda coloca a Sen en un terreno muy diferente al de Arrow. Se hacen explicitas las bondades de las comparaciones interpersonales y no oculta sus simpatías por las medidas cardinales de utilidad y bienestar. Muestra que si se acepta que un individuo j decide teniendo en cuenta el bienestar que experimentaría en el caso de encontrarse en una situación x de una persona i, no queda más remedio que hacer explícito el criterio de justicia que subyace a toda elección colectiva.

  14. Cosmic Censorship Conjecture in Kerr-Sen Black Hole

    CERN Document Server

    Gwak, Bogeun

    2016-01-01

    The validity of cosmic censorship conjecture for the Kerr-Sen black hole, which is a solution to the low-energy effective field theory for four-dimensional heterotic string theory, is investigated using charged particle absorption. When the black hole absorbs the particle, its charges are changed due to the conserved quantities of the particle. Changes in the black hole are constrained to the equation for the motion of the particle and are consistent with the laws of thermodynamics. Particle absorption increases the mass of the extremal Kerr-Sen black hole to more than its charges, so the black hole cannot be overcharged. Therefore, cosmic censorship conjecture is valid.

    success of social organizations. Second, his proposal for a valorization scheme that transcends the narrow conception of utilitarianism, which does not fall into ethical relativism and which incorpora tes the analysis of real rights and freedoms without taking refuge in deontological moral reasoning. With that, he demonstrates that one of his greatest contributions
    to normative economics is his effort to construct a framework
    for pluralist and consequentialist (based on consequences moral evaluation, which abandons the criterion of utility, allows the evaluation of the level of people's real freedom, and admits the possibility of a moral 'objective' sensitive to the life plans of individuals and to the achievement or fail of their rights.Este ensayo presenta dos aportes de Amartya Sen a las discusiones sobre ética y economía.

The aporia that exists in the current paradigm of human rights consists in the fact that it has been based on a few (liberal foundations, while, on the other hand, it has been extended into a broad system of individual rights/entitlements conflicting with their foundation. Each of those systems of rights entails a specific vision of social life. The liberal tradition postulates the existence of a minimal state, which guards freedom, life and property. In the leftist tradition, in contrast, there is postulated the existence of a welfare state, which satisfies people’s ever growing needs, based on an extensive bureaucracy and high taxes – under the patronage of the idea of social justice. Those social visions cannot be reconciled – they lead to conflicts. In this text, I present the problem of inconsistency and tension within the ‘human rights’, contrasting Amartya Sen’s theory with classical liberalism of John Locke. I claim that assessment of the contemporary ‘human rights’ theory should depend on whether a given theory is capable of proper determination and – at least to some extent – solving the problem of incoherence and tensions present in the Western ‘human rights’ paradigm. It seems that Sen’s conception cannot meet that challenge.

    Full Text Available Abstract Background Emergency Departments (EDs are confronted with progressive overcrowding. As a consequence, the workload for ED physicians increases and waiting times go up with the risk of unnecessary complications and patient dissatisfaction. To cope with these problems, Specialized Emergency Nurses (SENs, regular ED-nurses receiving a short, injury-specific course, were trained to assess and treat minor injuries according to a specific protocol. Methods An economic evaluation was conducted alongside a randomized controlled trial comparing House Officers (HOs and SENs in their assessment of ankle and foot injuries. Cost prices were established for all parts of healthcare utilization involved. Total costs of health care utilization were computed per patient in both groups. Cost-effectiveness was investigated by comparing the difference in total cost between groups with the difference in sensitivity and specificity between groups in diagnosing fractures and severe sprains. Finally, cost-effectiveness ratios were calculated and presented on a cost-effectiveness plane. Results No significant differences were seen between treatment groups for any of the health care resources assessed. However, the waiting times for both first assessment by a treatment officer and time spent waiting between hearing the diagnosis and final treatment were significantly longer in the HO group. There was no statistically significant difference in costs between groups. The total costs were € 186 (SD € 623 for patients in the SEN group and € 153 (SD € 529 for patients in the HO group. The difference in total costs was € 33 (95% CI: – € 84 to € 155. The incremental cost-effectiveness ratio was € 27 for a reduction of one missed diagnosis and € 18 for a reduction of one false negative. Conclusion Considering the benefits of the SEN-concept in terms of decreased workload for the ED physicians, increased patient satisfaction and decreased waiting times

    Full Text Available The Idea of Justice (TIJ by Amartya Sen appears as a proposal both to understand and defend global justice far from theories of justice supported on social contracts and transcendental institutional notions. The book can be regarded as a systematic attempt to show us how pertinent traditional social choice theory (from Condorcet to Arrow can be in order to develop a strong notion of justice that does not require neither a monolithic perspective nor a single institutional formulation. A. Sen propounds us to take care of patent injustices though we do not have a theory of justice, and even if we do not share central elements to this theory of justice. It is a real challenge for standard position in moral philosophy.

    En The Idea of Justice (TIJ de Amartya Sen se presenta una propuesta para comprender y defender la justicia global, alejada de las teorías de la justicia que se apoyan en el contrato social y en nociones institucionales trascendentales. El libro puede considerarse como un intento sistemático de defender la pertinencia de la tradición de la elección social (desde Condorcet a Arrow para una noción robusta de justicia que no requiera una visión monolítica ni una única formulación institucional. Nos propone atender a las injusticias patentes, aunque no tengamos una teoría de la justicia e incluso aunque no compartamos elementos centrales para esa teoría de la justicia. Es un auténtico desafío a la posición estándar en filosofía moral.

  17. Cosmic censorship conjecture in Kerr-Sen black hole

    2017-06-01

    The validity of the cosmic censorship conjecture for the Kerr-Sen black hole, which is a solution to the low-energy effective field theory for four-dimensional heterotic string theory, is investigated using charged particle absorption. When the black hole absorbs the particle, the charge on it changes owing to the conserved quantities of the particle. Changes in the black hole are constrained to the equation for the motion of the particle and are consistent with the laws of thermodynamics. Particle absorption increases the mass of the Kerr-Sen black hole to more than that of the absorbed charges such as angular momentum and electric charge; hence, the black hole cannot be overcharged. In the near-extremal black hole, we observe a violation of the cosmic censorship conjecture for the angular momentum in the first order of expansion and the electric charge in the second order. However, considering an adiabatic process carrying the conserved quantities as those of the black hole, we prove the stability of the black hole horizon. Thus, we resolve the violation. This is consistent with the third law of thermodynamics.

For the latter purpose, Rawls' metric of primary goods is preferable.

    Full Text Available Teori “Benturan Peradaban” karya Samuel Huntington memiliki kebenarannya sendiri jika dilihat dari perspektif esensialis atau ajaran agama yang bernuansa eksklusif dan dipahami secara literalis radikal. Dalam konsepsi muslim eksklusif atau literalis radikal, term “jihad” dapat menjadi senjata ampuh untuk melakukan benturan peradaban ini. Oleh karena itu diperlukan upaya: Pertama, penggabungan spritualitas agama dengan keutamaan paham kebebasan. Kedua, dialektika simbiosis antar peradaban. Demikian juga argumen dan kritik Amartya Sen terhadap teori Benturan Peradaban, juga memiliki kebenarannya jika dilihat dari ajaran agama yang bertujuan teraplikasikannya nilai-nilai perdamaian. Karena menurutnya, setiap pemeluk agama memiliki keragaman identitas yang tidak hanya dibatasi oleh nilai-nilai agama, tetapi juga identitas lainnya berdasarkan nilai-nilai sosial, ekonomi, atau budaya. Oleh karena itu diperlukan analisis berdasarkan teori-teori sosial yang bersifat empirik dalam menghadapi atau mengantisipasi adanya konflik, baik konflik disebabkan oleh pemahaman keliru atau tidak utuh tentang agama atau aspek lainnya dari konflik peradaban.

    Decision-making for sustainable environmental resource management or risk prevention is facing the problem of constantly changing conditions related to the projected changes of climate, demography and socio-economy. Herefore, adaptable tools and methods which can reflect such changes are needed for an efficient management. The need to improve existing tools is a challenge the departments of German environmental authorities at state and federal level are facing at this time. Additionally the increasing demands for work process optimization due to financial cutbacks are coming into play. Consequently the need for suitable adaptation measurements for short and long term changes of environmental state variables is growing. The importance of spatio-temporal data, providing continuous observation about the state of the environmental system and its changes, is therefore increasing in order to elaborate adaptation strategies. In this case earth observation is a useful source for the required data. With the new Sentinel fleet, ESA's Copernicus Program is providing a possibility to obtain such information free in high temporal and spatial resolution. The BMVI funded project SenThIS, a collaborative project by the Thuringian State Institute for Environment and Geology (TLUG), the Thuringian Forest Department and two SMEs EOS GmbH and Feiffer consult is aiming at utilizing Copernicus data and services for operational tasks on a federal level. It addresses this aforementioned deficit through the development and implementation of a processing chain for synergetic and automated application of remote sensing data and products to accomplish operational state tasks. The product development is characterized by the synergetic application of remote sensing data and suitable models. Design and calibration of the models base on Sentinel 1/2 data and additional information (e.g. meteorological data, in-situ measurements). This results in products of highly temporal and spatial resolution

    Full Text Available Zur medikamentösen Behandlung des benignen Prostatasyndroms (BPS stehen primär Alpha-Blocker und 5-Alpha-Reduktaseinhibitoren (5ARI, aber auch Phytopräparate und Anticholinergika zur Verfügung. Diese Präparate werden als Monotherapie bzw. zum Teil auch in Kombination eingesetzt. Hierbei zeichnen sich α-Blocker durch einen schnellen Wirkungseintritt (Stunden bis Tage aus. Alle Alpha-Blocker sind bei adäquater Dosierung ähnlich wirksam, quantitative Unterschiede zeigen sich im Nebenwirkungsprofil. 5ARI wirken erst nach Monaten und vorwiegend bei Patienten mit einem Prostatavolumen 30 ml. Im Gegensatz zu einer Therapie mit Alpha-Blockern werden durch 5ARI Prostatagröße und langfristige Komplikationen wie akuter Harnverhalt oder die Notwendigkeit einer Prostataoperation reduziert. Im Falle einer Langzeitbehandlung über mehrere Jahre ist eine Kombination von α-Blocker plus 5ARI den jeweiligen Monotherapien überlegen. Aufgrund der ebenfalls additiven Nebenwirkungen kommt eine solche Kombinationsbehandlung vor allem für Patienten mit hohem Progressionsrisiko infrage. Für Phytopharmaka kann wegen der unzureichender Datenlage keine generelle Empfehlung abgegeben werden. Die Behandlung mit Anticholinergika in Kombination mit einem α-Blocker bei Patienten mit Symptomen der überaktiven Blase bei BPS ohne relevante infravesikale Obstruktion erscheint vielversprechend, auch wenn weitere Studien, insbesondere mit einem längeren Beobachtungszeitraum, notwendig sind.

  12. Sen1p contributes to genomic integrity by regulating expression of ribonucleotide reductase 1 (RNR1 in Saccharomyces cerevisiae.

    Directory of Open Access Journals (Sweden)

    Upendarrao Golla

    Full Text Available Gene expression is a multi-step process which requires recruitment of several factors to promoters. One of the factors, Sen1p is an RNA/DNA helicase implicated in transcriptional termination and RNA processing in yeast. In the present study, we have identified a novel function of Sen1p that regulates the expression of ribonucleotide reductase RNR1 gene, which is essential for maintaining genomic integrity. Cells with mutation in the helicase domain or lacking N-terminal domain of Sen1p displayed a drastic decrease in the basal level transcription of RNR1 gene and showed enhanced sensitivity to various DNA damaging agents. Moreover, SEN1 mutants [Sen1-1 (G1747D, Sen1-2 (Δ1-975] exhibited defects in DNA damage checkpoint activation. Surprisingly, CRT1 deletion in Sen1p mutants (Sen1-1, Sen1-2 was partly able to rescue the slow growth phenotype upon genotoxic stress. Altogether, our observations suggest that Sen1p is required for cell protection against DNA damage by regulating the expression of DNA repair gene RNR1. Thus, the misregulation of Sen1p regulated genes can cause genomic instability that may lead to neurological disorders and premature aging.

    Navarro, V

    2000-01-01

    Presented here is a critical analysis of some of the major theses of Amartya Sen, as presented in his seminal work Development As Freedom. The author suggests that Sen's work, while representing a major break with the dominant neoliberal position reproduced in most national and international development agencies, is insufficient to explain the key relationship between freedom and development. The absence of an analysis of the power relations that cause and reproduce underdevelopment through national and international political institutions leaves Sen's work wanting. The author shows how Sen's interpretation of events and the conclusions derived from them, such as an explanation of famine in Bangladesh, are insufficient--when not faulty. The author also critically analyzes the United Nations Development Program reports, which, while documenting the nature and consequences of underdevelopment, barely touch on the political context in which underdevelopment occurs.

    Full Text Available The article discusses the idea of ‘human rights’ and the Amartya Sen’s reflections on that topic. By assumption, Sen does not present a catalogue of human rights, yet he claims that the language of human rights can be used to talk about the so-called human capabilities (the main concept of Sen’s theory. The aporia that exists in the current paradigm of human rights consists in the fact that it has been based on a few (liberal foundations, while, on the other hand, it has been extended into a broad system of individual rights/entitlements conflicting with their foundation. Each of those systems of rights entails a specific vision of social life. The liberal tradition postulates the existence of a minimal state, which guards freedom, life and property. In the leftist tradition, in contrast, there is postulated the existence of a welfare state, which satisfies people’s ever growing needs, based on an extensive bureaucracy and high taxes – under the patronage of the idea of social justice. Those social visions cannot be reconciled – they lead to conflicts. In this text, I present the problem of inconsistency and tension within the ‘human rights’, contrasting Amartya Sen’s theory with classical liberalism of John Locke. I claim that assessment of the contemporary ‘human rights’ theory should depend on whether a given theory is capable of proper determination and – at least to some extent – solving the problem of incoherence and tensions present in the Western ‘human rights’ paradigm. It seems that Sen’s conception cannot meet that challenge.

    Full Text Available Introduction Torque teno virus (TTV and SEN virus are circular single-stranded DNA viruses that cause blood-borne infections. The SEN virus (SEN-V was originally detected in the serum of an injection drug user infected with human immunodeficiency virus (HIV. Recently TTV was discovered as a potential causative agent of non-A-E hepatitis. The aim of this study was to investigate the prevalence of the SEN-V-D/H and TTV in HIV patients and healthy blood donors in Iran. Methods One hundred and fifty HIV patients with a mean age of 50.46 ± 18.46 years and 150 healthy blood donors with a mean age of 48.16 ± 13.73 years were included in this study. TTV and SEN-V were detected by the PCR and were quantitatively assayed by competitive PCR (nested and semi-nested PCR. Restriction fragment length polymorphisms (RFLPs were used to determine the heterogeneity of TTV. Results TTV and SEN-V were detected 96 (64% and 84 (56% of 150 HIV patients respectively. These rates were 34% (n=51 and 37.33% (n=56 in healthy blood donors (significant, p<0.05. PCR detected SEN-V/TTV DNA from 32 of the healthy blood donors (21.33%, while 65 (43.33% of HIV patients were positive for SEN-V/TTV DNA. Of 150 HIV patients, 32.66% and 23.33% were positive for SEN-V-H and SEN-V-D, respectively and 18.66% (n=28 were co-infected with SEN-V-D/H. Conclusions The prevalence of SEN-VD/H and TTV is higher in HIV patients than in healthy blood donors in Southern Iran. Our results suggest that TTV and SEN-V might play a role in the development of liver disease in patients with immunodeficiency diseases.

    Two Serratia marcescens strains, SEN and ICC-4, isolated from diseased insect cadavers were observed to differ considerably in their virulence towards Spodoptera litura. The present study was aimed to characterize the possible virulence factors present in the virulent Serratia marcescens strain SEN. Both the S. marcescens strains were evaluated for the presence of various lytic enzymes such as chitinase, lipase, protease and phospholipase. The virulent S. marcescens strain SEN was observed to possess considerably higher activity of chitinase and protease enzymes; activity of phospholipase enzyme was also higher. Although, all the three toxin genes shlA, phlA and swr could be detected in both the S. marcescens strains, there was a higher expression of these genes in the virulent strain SEN. S. marcescens strain ICC-4 showed greater reduction in overall growth yield in the post-exponential phase in the presence of midgut juice and hemolymph of S. litura larvae, as compared to S. marcescens strain SEN. Proliferation of the S. marcescens strain SEN was also considerably higher in foregut, midgut and hemolymph of S. litura larvae, as compared to strain ICC-4. Peritrophic membrane treated with broth culture of the S. marcescens strain SEN showed higher damage as compared to strain ICC-4. The peritrophic membrane of larvae fed on diet treated with the virulent strain showed considerable damage while the peritrophic membrane of larvae fed on diet treated with the non-virulent strain showed no damage. This is the first report documenting the fate of ingested S. marcescens in S. litura gut and the relative expression of toxin genes from two S. marcescens strains differing in their virulence towards S. litura.

Mittels Fallbeispielen zur religiösen Bildung am religiösen Markt (= religiöse Institutionen außerhalb des Schulraums wird in diesem Beitrag aufgezeigt, dass der islamische Religionsunterricht im Gegensatz zu den religiösen Institutionen keine Monopolkirche sein darf, in der vorwiegend eine Art Volksfrömmigkeit vermittelt wird. Opportunities and Challenges of Religious Education in Schools – A Muslim Perspective This contribution is based on the argument that the role of Islamic religious education at schools should be reconceived in relation to the growing presence of origin-oriented religious institutions in Europe. In addition to the origin-oriented religious institutions in Europe, this paper aims to present the importance of Islamic religious education from the perspective of contextualized Islam. Based on case studies for religious education in the religious market (outside the education area this paper shows that the Islamic religious education cannot offer Church`s monopoly and act like origin-oriented religious institutions to mediate popular piety.

  5. Liberdade e Poder em Amartya Sen: uma Leitura Crítica

    Directory of Open Access Journals (Sweden)

    Valter Lúcio de Oliveira

    2007-01-01

    Full Text Available As evidenced in the title, this article presents a critical analysis of several proposals developed by Amartya Sen. It makes two central critiques of Sen’s work; highlighting the absence of arguments that take into account relationships of power, as well as the lack of an emphasis on the relationship between the individual and society. At the same time, evidence will be presented that Sen’s perspective is not an alternative to the dominant economic discourse, neither in its analytic intent or its normative orientation. One can conclude that his proposals are presented, more appropriately, as a sophisticated theory of the principles that presently govern liberalism. Therefore, his formulations do not differ much from those that are currently being implemented in the majority of countries.

    2015-02-01

    Epigenotoxicology needs simple and fast tools to assess xenobiotic epigenetic load. This work proposes a comet assay modification designed to detect global methylation changes (Methy-sens Comet) through enzymatic digestion with two restriction enzymes (HpaII, MspI). In the methylation-sensitive protocol tested for repeatability on A549 cells, nickel chloride induced hypermethylation and decitabine-induced hypomethylation. A concomitant assessment of DNA methyltransferases (DNMTs) genes transcriptional levels has been performed, to implement a multifunctional approach to epigenotoxicology. Methy-sens Comet showed a general good repeatability and sensitivity to methylation changes while DNMTs transcriptional levels granted additional proof of xenobiotic-induced impairment of methylome maintenance.

Sen usa de una manera particular los conceptos de la simpatía y del espectador imparcial para elaborar su noción de justicia. Más allá de la afirmación de Sen, estamos interesados en indagar si la noción de justicia de Smith es compatible con la que propone Sen. El principal hallazgo es que hay diferencias significativas entre las teorías y, por tanto, no son compatibles. Smith enfatizó la importancia del juicio moral basado en el sentimiento. Por el contrario, Amartya Sen enfatiza la necesidad de utilizar la razón y el debate público como elementos claves de una teoría de la justicia.

    We examined channel bars at two sites in the lower reach of the Stung Sen River, which flows into Lake Tonle Sap, Cambodia, to identify sediment transport and accumulation processes during monsoon-related flood events and to investigate how sediment transport capacity changes as a result of enhanced backwater effect of the lake. Channel bars in the lower reach of the Stung Sen River that emerge in the dry season were classified into type A (lateral bars), type B (point bars), type C (concave-bank benches) and type D (diagonal and island bars, or fluvial dunes) based on Nagumo et al.'s previous study. Type B, type C, and type D channel bars were at our study sites of SEN-01 and SEN-02, about 83 and 77 km from the river mouth respectively. Computation of water surface profiles showed that sediment transport capacity of the Stung Sen River decreased abruptly after the peak flow stage because of the backwater effect from Lake Tonle Sap during the decreasing flow stage. Our observations suggest that alternating layers of sand and silt to clay layers accumulate to form type C channel bars, corresponding to changes in sediment transport capacity controlled by backwater effects from Lake Tonle Sap and by changes in flow depths and associated slackwater systems. The accumulation of alternating silt and sand layers of type B channel bars results from lateral sediment transportation that is accelerated with an increase of secondary flow, whereas development of type D channel bars is related to bedload mobility.

    Standardised health-related quality of life questionnaires play an increasing role as measures of outcome in the evaluation of health care interventions. However, problems can arise when the selected functions or dimensions of such standardised measures are not in line with the intervention that is the focus of the research. Furthermore, the subjective element of quality of life makes standardised questionnaires vulnerable to the coping mechanism, thereby decreasing their sensitivity. The capability approach of the economist and philosopher Amartya Sen offers a descriptive concept that contributes to a better understanding of these problems. This article provides an introduction to the ideas of Sen for researchers who wish to go beyond the traditional framework of measuring health-related quality of life.

    IIB compactifications enjoy the possibility to break GUT groups via fluxes without giving mass to the hypercharge gauge field. Although this important advantage has greatly motivated F-theory constructions, no such fluxes have been constructed directly in terms of the M-theory $G_4$-form. In this note, we give a general prescription for constructing hypercharge G-fluxes. By using a stable version of Sen's weak coupling limit, we verify their connection with IIB fluxes.

    Full Text Available Background:Transposition of the great arteries (TGA is the most common cyanotic cardiopathy, with an incidence ranging between 0.2 and 0.4 per 1000 live births. Many patients not treated in the first few months of life may progress with severe pulmonary vascular disease. Treatment of these patients may include palliative surgery to redirect the flow at the atrial level.Objective:Report our institutional experience with the palliative Senning procedure in children diagnosed with TGA and double outlet right ventricle with severe pulmonary vascular disease, and to evaluate the early and late clinical progression of the palliative Senning procedure.Methods:Retrospective study based on the evaluation of medical records in the period of 1991 to 2014. Only patients without an indication for definitive surgical treatment of the cardiopathy due to elevated pulmonary pressure were included.Results:After one year of follow-up there was a mean increase in arterial oxygen saturation from 62.1% to 92.5% and a mean decrease in hematocrit from 49.4% to 36.3%. Lung histological analysis was feasible in 16 patients. In 8 patients, pulmonary biopsy grades 3 and 4 were evidenced.Conclusion:The palliative Senning procedure improved arterial oxygen saturation, reduced polycythemia, and provided a better quality of life for patients with TGA with ventricular septal defect, severe pulmonary hypertension, and poor prognosis.

  10. Null geodesics and observables around the Kerr–Sen black hole

    2018-01-01

    We investigate the geodesic motion in the background of the Kerr–Sen black hole arising in heterotic string theory. The nature of the effective potential is discussed in the radial, as well as latitudinal, direction. A special class of spherical photon orbits is obtained along with an expression for the turning point for the radial photons. Dependence of photon motion within this class of solution is discussed explicitly in view of the different black hole parameters. We have discussed the allowed regions for the geodesic motion of massless test particles around the Kerr–Sen black hole in a more generalised way by considering non-equatorial motion of the photons into account. The conditions for different types of possible orbits are discussed with specific parameter values along with the corresponding orbit structure. No terminating orbits are possible for photons due to non-zero black hole charge. Observables on the angular plane (viz. bending of light and perihelion precession for massive test particles) are analysed as special cases. We have also calculated the rotation and mass parameters for the Kerr–Sen black hole in terms of the red/blue shifts of the photons in circular and equatorial orbits emitted by the massive test particles which represent stars or other probable sources of photons.

    It is reported that Kerr-Newman and Kerr-Sen black holes are unstable to perturbations of charged massive scalar field. In this paper, we study analytically the complex frequencies which characterize charged massive scalar fields in a near-extremal Kerr-Sen black hole. For near-extremal Kerr-Sen black holes and for charged massive scalar fields in the eikonal large-mass M ≫μ regime, where M is the mass of the black hole, and μ is the mass of the charged scalar field, we have obtained a simple expression for the dimensionless ratio ωI/(ωR-ωc) , where ωI and ωR are, respectively, the imaginary and real parts of the frequency of the modes, and ωc is the critical frequency for the onset of super-radiance. We have also found our expression is consistent with the result of Hod [Phys. Rev. D 94, 044036 (2016), 10.1103/PhysRevD.94.044036] for the case of a near-extremal Kerr-Newman black hole and the result of Zouros and Eardly [Ann. Phys.

Common formulations of impossibility theorems of K. J. Arrow and A. K. Sen are represented by the statements of the form "there is no x such that A". Bearing in mind logical equivalence of formulae ¬ЭxA and x¬A, we come to the conclusion that the corpus of impossibility theorems, which appears in the theory of social choice, could make a specific and recognizable subclass of universal statements. In this paper, on the basis of the established logical and methodological criteria, we point to a sequence of extremely significant "impossibility theorems", reaching throughout the history of mathematics to the present days and the famous results of Arrow and Sen in field of mathematical economics. We close with specifying the context which makes it possible to formulate the results of Arrow and Sen accurately, presenting a new direct proof of Sen’s result, with no reliance on the notion of minimal liberalism. .

    Amartya Sen's capability approach characterizes an individual's well-being in terms of what they are able to be, and what they are able to do. This framework for thinking has many commonalities with the core ideas in career guidance. Sen's approach is abstract and not in itself a complete or explanatory theory, but a case can be…

  15. ENERGY EFFICIENCY AND ROUTING IN SENSOR NETWORKS

    Cetin, Bilge Kartal

    for long time' or 'long network lifetime' can be determined as a common performance requirement for the most of the applications. Energy depletion of the nodes can interrupt communication and, in a worse case, it could cause network partitioning which leads the interruption of monitoring. Unlike ad......-hoc networks, recharging or replacing of the sen- sors battery may be inconvenient, or even impossible in some monitoring environments. Therefore, the key challenge in the design of wireless sen- sor network protocols is how to maximize the network lifetime, which is limited by battery energy in sensor nodes......, while providing the application requirement. In sensor networks, there are two important energy consuming pro- cesses, the rst is transmission-reception phase and the second is listening the radio for any possible event. Therefore, there are two strategies for en- ergy saving. The rst is reducing...

    Full Text Available The Sun Yat Sen shophouse in Penang is a small private Museum, which was converted from a shophouse or townhouse situated in the Armenian Street heritage area of George Town. The building is an example of embraces of the architectural heritage of George Town which is an extraordinarily beautiful example of Straits Settlements merchant's shophouse. Historically, it is associated with the global historical personality of Dr. Sun Yat Sen and his revolutionary. This city was added to the UNESCO's world heritage list in 2008 to acknowledge its rich cultural heritage that constitutes of unique architectural and cultural townscape along the Straits of Melaka. This paper investigates the architectural plan of a shophouse and the values of cultural heritage buildings which eventually was converted into a Museum in George Town, Penang. Classified as an eclectic style shophouse, it is rich in design and art components featured in its architecture that are still sustaining until today. This building has an interesting mixture of architectural and cultural inspirations adapted from the Chinese origin, with the local Malay ethnicity and the European influences that colonised the region. The introduction of new non related architectural components into the southern Chinese (eclectic style style in shophouses in George Town has resulted in the disappearance of this unique style of architecture. This investigation employs a qualitative research approach by documenting evidence and understanding the architectural as well as cultural influences of the southern Chinese eclectic style by studying the Sun Yat Sen Museum as a case study. The findings of the research point towards an understanding of the architectural and cultural influences that govern the design of the shophouse and its architectural character. Key words: sustainable architectural values, George Town, eclectic style, shophouses

  19. Identidad Social en Amartya Sen: vinculando libertad y responsabilidad en democracia

    Directory of Open Access Journals (Sweden)

    Carvajal Muñoz, María Rosario

    2015-10-01

    Full Text Available Social identity is plural, ambiguous, chosen, neither inherited nor merely discovered, and coexists harmoniously with other identities (Sen, 2001, p. 319. Identities related to capabilities, an aspect of freedom understood as the individual’s willingness to choose from among the substantive opportunities that exist (Sen, 2004, p. 520. At present, some identities are being constructed and reinforced, but others are being weakened, such as those relating to work. This text insists on the need to think about the connection between identity, freedom and responsibility. Identity without freedom is a chimera, but it is also impossible for identity and freedom to be present without responsibility, because identity is an option that is chosen, and as an action, needs both individual responsibility as well as responsibility to others. This enables the substantive opportunities that make it effective. This work is relevant because the existing literature does not stop to analyse these relationships explicitly.La identidad social es plural, no unívoca, elegida, no heredada ni meramente descubierta, y en convivencia armónica con otras identidades (Sen, 2001, p. 319. Las identidades remiten al término de capacidad, un aspecto de la libertad entendido como la disposición a elegir de los individuos a partir de la existencia de oportunidades sustantivas (Sen, 2004, p. 520. En la actualidad se construyen y refuerzan algunas identidades, pero también se debilitan otras, como las que afectan al ámbito laboral. Este texto insiste en la necesidad de reflexionar en la vinculación existente entre identidad, libertad y responsabilidad. La identidad sin libertad se hace quimera, pero la presencia de identidad y libertad sin responsabilidad se hace también imposible. Porque la identidad como opción que se elige, y que implica una acción, necesita tanto de la responsabilidad individual como de la responsabilidad para con otros posibilitando oportunidades

    Full Text Available Se4+ and N3− ions were used as codopants to enhance the photocatalytic activity of TiO2 under sunlight irradiation. The Se/N codoped photocatalysts were prepared through a simple wet-impregnation method followed by heat treatment using SeCl4 and urea as the dopant sources. The prepared photocatalysts were well characterized by X-ray diffraction (XRD, X-ray photoelectron spectroscopy (XPS, UV-diffuse reflectance spectroscopy (UV-DRS, scanning electron microscopy (SEM and Raman spectroscopy. The codoped samples showed photoabsorption in the visible light range from 430 nm extending up to 580 nm. The photocatalytic activity of the Se/N codoped photocatalysts was evaluated by degradation of 4-nitrophenol (4-NP. The degradation of 4-NP was highly increased for the Se/N codoped samples compared to the undoped and single doped samples under both UV-A and sunlight irradiation. Aiming to determine the electronic structure and dopant locations, quantum chemical modeling of the undoped and Se/N codoped anatase clusters was performed using Density Functional Theory (DFT calculations with the hybrid functional (B3LYP and double-zeta (LanL2DZ basis set. The results revealed that Se/N codoping of TiO2 reduces the band gap due to mixing of N2p with O2p orbitals in the valence band and also introduces additional electronic states originating from Se3p orbitals in the band gap.

Se incluye, además, la descripción del recién planteado modelo de la diversidad. Tras ello, se describen los elementos esenciales del enfoque de capacidades y funcionamientos de Amartya Sen y su relación con los logros de bienestar, calidad de vida y libertad por parte de las personas. A continuación se exponen las dos clasificaciones de la OMS que abordan la cuestión de la discapacidad: la Clasificación Internacional de Deficiencias, Discapacidades y Minusvalías (CIDDM, de 1980, y la Clasificación Internacional del Funcionamiento, la Discapacidad y la Salud (CIF, de 2001. La noción de discapacidad se introduce en el enfoque de capacidades y funcionamientos a raíz de la importancia que otorga Sen a la diversidad de características propias y externas de las personas a la hora de valorar la desigualdad en el logro de funcionamientos valiosos. Nuestra propuesta es que el "conjunto capacidad" (que es el formado por todos los funcionamientos al alcance de la persona, y que así engloba sus diferentes formas y estilos de vida posibles no debe limitarse a recoger el conjunto de funcionamientos posibles de una persona "normal", sino que debería ampliar su marco para dar cabida igualmente a los funcionamientos diversos posibles para otras personas, al margen de esa ficción de "normalidad". Esta propuesta, es plenamente coherente con la importancia de la diversidad de las características humanas y circunstancias ambientales en el planteamiento de Amartya Sen, y de hecho lo amplía al incorporar esa misma diversidad en el conjunto de funcionamientos posibles que constituyen el conjunto capacidad de la persona.

Les pratiques en question – qui sont à la fois discursives et didactiques – consistent à construire un contexte fictionnel ou réel autour d’un élément à transmettre, pouvant être un mot, une expression ou encore un acte langagier, dans le but d’illustrer le sens de ce dernier. A travers l’analyse des transcriptions des interactions en classe de FLE (public adulte on mettra en évidence la diversité des moyens discursifs que les participants à l’interaction didactique utilisent dans la construction des contextes et on proposera la description du fonctionnement de ces derniers que l’on développera d'une part en nous appuyant sur la conceptualisation du contexte en linguistique interactionnelle, et d'autre part à partir de la notion du cadre de l’expérience (Goffman. Concernant ce dernier point, on insistera sur le fait que les « prémisses organisationnelles » des cadres jouent un rôle crucial dans la transmission des connaissances à travers la construction discursive des contextes car, d’une part, ils représentent les mécanismes qui permettent d’interpréter une situation construite et de ce fait, d’accéder au sens d’un élément à transmettre, et d’autre part, ces schèmes interprétatifs peuvent eux-mêmes faire partie du contenu à enseigner/apprendre. En outre, on soulignera que, dans la mesure où les cadres s’inscrivent dans la culture d’un groupe social donné, les contextes construits dans le discours véhiculent inévitablement une part de culturel.

    Portugal is experiencing a technological reform in education. Technological refurbishing of schools and training of students and teachers is a reality on the rise, enhanced by the implementation of the Education Technological Plan, which also aims at computer skills certification, by 2010, of 90% of teachers. In a School that must be adjusted to all pupils, Special Educational Needs cannot be neglected and the nature and constitution of its computer resources should obviate the support of these students. ICT training is essential to benefit all students from its use. In the case of SEN, this need for training is of paramount importance to establish itself as a facilitator for these students. ICT Coordinators are the visible face of ICT implementation in schools; their functions include the management of the schools computer facilities and to zeal for the ICT training of fellow teachers.

    Dastan, Sara; Soroushfar, Saheb

    2016-01-01

    We analyze the shadow of charged stationary axially symmetric space-time (Kerr-Sen dilaton-axion black hole). This black hole is defined by a mass $M$, a spin $a$ and $r_{\\alpha}=Q^{2}/M$, where $Q$ is the electric charge. Shadows are investigated in two conditions, i) for an observer at infinity in vacuum and ii) for an observer at infinity in the presence of plasma with radial power-low density. In vacuum, the shadow of this black hole depends on charge and spin parameter. We can see that, increasing electric charge, $Q$ decreases the size of shadow. Also, increasing spin parameter $a$ decreases the size of shadow. However, in existence of plasma, parameter of plasma like refraction index, $n$, playing an important role on shadows. In fact, decreasing refraction index decreases the size of shadow.

    Given the high prevalence of the hyponutrition state among haemodialysis patients and knowing that this implies an increase in the rates of infection, hospitalisation and hospital stay, which translates into an increase in global morbid-mortality, the Spanish Society of Nephrology (SEN) and the Spanish Society of Parenteral and Enteral Nutrition (SENPE) have reached a consensus on the indications, contraindications, and limitations of Intra-Dialysis Parenteral Nutrition (IDPN.) This consensus considers IDPN as a valid alternative to other types of nutritional support when these show their lack of efficacy. The bases are set regarding the timing of nutritional intervention with IDPN, its ideal composition, the time of administration, its controls, follow-up schedules, and the time at which the nutritional support has to be discontinued.

    The market of Silicon Photomultipliers (SiPMs) consists of many manufacturers that produce their detectors in different technology. Hamamatsu (Japan) and SensL (Ireland) seems to be the most popular companies that produce large SiPM arrays. The aim of this work is characterization and comparison of 4×4 channel SiPM arrays produced by these two producers. Both of the tested SiPMs are made in through-silicon via (TSV) technology, consist of 16, 3×3 mm avalanche photodiode (APD) cells and have fill factor slightly above 60%. The largest difference is a single APD cell size and hence total number of APD cells (55,424 for Hamamatsu, 76,640 for SensL). In the case of SensL SiPM, its spectral response characteristics is shifted slightly toward shorter wavelengths with maximum at 420 nm (450 nm for Hamamatsu). The presented measurements cover selection of the SiPM optimum operating voltage (in respect to energy resolution), verification of the excess noise factor and check of the linearity characteristics. Moreover, the gamma spectrometry with LSO, BGO and CsI:Tl scintillators together with pulse characteristics for these crystals (rise time and fall time) is reported, as well as temperature dependence. The presented measurements show better performance of the SensL array comparing to the Hamamatsu detector.

    Full Text Available Le présent article s'inscrit dans une perspective de linguistique de corpus. Il porte sur des questions de veille lexicale et, plus précisément, sur le phénomène de néologie sémantique. Il aborde le problème de l'acquisition automatique d'un nouveau sens, qui implique d'une part la détection d'un changement, d'autre part, la caractérisation du nouveau sens relativement au sens connu. L'émergence d'un nouveau sens en discours et sa stabilisation dans la langue peuvent se concevoir comme un processus caractérisé par une double diffusion, thématique et temporelle, et par des interactions avec les sens déjà répertoriés dans des ressources lexicographiques. Nous proposons les grandes lignes d'une procédure pour mettre en évidence la double diffusion en corpus, pour extraire des étiquettes de domaines susceptibles de qualifier le nouveau sens et pour articuler l'information sémantique issue du corpus au sens codé dans un dictionnaire. La démarche est illustrée à chaque étape par l'étude d'un ensemble de cibles lexicales dans deux types de ressource, un corpus de presse des années 2000 partitionné en différents domaines et un dictionnaire de langue, le Trésor de la Langue Française informatisé. L'analyse repose sur des découpages multiples de l'espace des ressources, notamment du corpus, et sur l'exploitation de ces découpages à l'aide d'outils lexicométriques, à savoir le calcul de spécificités.

  8. Numerical and Physical Study on a Cylindrical Tundish Design to Produce a Swirling Flow in the SEN During Continuous Casting of Steel

    A new tundish design was investigated using both water model experiments and numerical simulations. The results show that the Reynolds Stress Model simulation results agree well with the Particle Image Velocimetry-measured results for water model experiments. A strong swirling flow in the Submerged Entry Nozzle (SEN) of the new tundish was successfully obtained, and the tangential velocity in the region near SEN inlet could reach a value of around 3.1 m/s. A high value of the shear stress was found to exist on the SEN wall, due to the strong swirling flow inside the SEN. This large shear stress leads to the dissipation of the rotational momentum of the steel flow. Thus, the maximum tangential velocity of the steel flow decreases from 3.1 m/s at around the SEN inlet to 2.2 m/s at a location close to the SEN outlet. In addition, the near-wall region has a high pressure, which is larger than the atmospheric pressure, due to the centrifugal effect. The calculated swirl number, with the value of around 1.6 at SEN inlet, illustrates that the current design can produce a similar strong swirling flow compared to the swirl blade method and the electromagnetic stirring method, while this is obtained by simply changing the steel flow path in tundish instead of using additional device to influence the flow.

    By China's entry into the WTO, Chinese as well as German companies are facing the question, how to minimize the risk of unfamiliar cooperation partners when developing products. The rise of customer demands concerning quality, product diversity and the reduction of expenses require flexibility and efficiency with reliable component suppliers. In order to build and strengthen sino-german cooperations, a manufacturing control using homogenized and efficient measures to assure high quality is of vital importance. Lack of unifications may cause identical measurements conducted at subcontractors or customers to be carried out with different measurement processes which leads to incomparable results. Rapidly growing company cooperations and simultaneously decreasing of manufacturing scope cause substantial difficulties when coordinating joint quality control activities. "ProSens," a sino-german project consortium consisting of industrial users, technology producers and research institutes, aims at improving selected production processes by: Creation of a homogeneous quality awareness in sino-german cooperations. Sensitization for process accompanying metrology at an early stage of product development. Increase of the process performance by the use of integrated metrology. Reduction of production time and cost. Unification of quality control of complex products by means of efficient measurement strategies and CAD-based inspection planning.

    Full Text Available This text deal with the approach of the capability, identified with the facets of freedom of individuals to reach goals, and that have necessity of substantive opportunities as result of a bigger liberty, the positive liberty. The freedom facets of Amartya Sen are used to determine the elements to constitute the political capability term. The paper distinguishes two dimensions of democracy: democracy as process and democracy as result. The political freedom has its centre into the democracy as process, with repect to the citizenship participation in public issues. The another dimension refers to the democracy as result concerning policies and its effects on the population. Both dimensions affect to the political capabilities of the citizenship. The political capabilities, as freedom of individuals and groups, are possible if the democracy offers opportunities to satisfy necessities and political participations. According to this approach of political capacibility, if a democracy reduces opportunities and restricts the ways of public participation by citizens, then it is restricting the political capabilities (freedom, and even this limitations shorten others fundamental liberties of the citizens.

  16. Spatial Preference Modelling for equitable infrastructure provision: an application of Sen's Capability Approach

    2014-01-01

    To determine whether the inclusion of spatial neighbourhood comparison factors in Preference Modelling allows spatial decision support systems (SDSSs) to better address spatial equity, we introduce Spatial Preference Modelling (SPM). To evaluate the effectiveness of this model in addressing equity, various standardisation functions in both Non-Spatial Preference Modelling and SPM are compared. The evaluation involves applying the model to a resource location-allocation problem for transport infrastructure in the Special Province of Yogyakarta in Indonesia. We apply Amartya Sen's Capability Approach to define opportunity to mobility as a non-income indicator. Using the extended Moran's I interpretation for spatial equity, we evaluate the distribution output regarding, first, `the spatial distribution patterns of priority targeting for allocation' (SPT) and, second, `the effect of new distribution patterns after location-allocation' (ELA). The Moran's I index of the initial map and its comparison with six patterns for SPT as well as ELA consistently indicates that the SPM is more effective for addressing spatial equity. We conclude that the inclusion of spatial neighbourhood comparison factors in Preference Modelling improves the capability of SDSS to address spatial equity. This study thus proposes a new formal method for SDSS with specific attention on resource location-allocation to address spatial equity.

    Full Text Available SEN virus (SENV is a circular, single stranded DNA virus that has been first characterized in the serum of a human immunodeficiency virus type 1 (HIV-1-infected patient. Eight genotypes of SENV (A-H have been identified and further recognized as variants of TT virus (TTV in the family Circoviridae. Here we describe the first genomic characterization of a SENV isolate (5-A from South America. Using 'universal' primers, able to amplify most, if not all, TTV/SENV genotypes, a segment of > 3 kb was amplified by polymerase chain reaction from the serum of an HIV-1 infected patient. The amplicon was cloned and a 3087-nucleotide sequence was determined, that showed a high (85% homology with the sequence of the Italian isolate SENV-F. Proteins encoded by open reading frames (ORFs 1 to 4 consisted of 758, 129, 276, and 267 amino acids, respectively. By phylogenetic analysis, isolate 5-A was classified into TTV genotype 19 (phylogenetic group 3, together with SENV-F and TTV isolate SAa-38.

    Full Text Available El objetivo de este trabajo es analizar el concepto de equidad educativa desde la perspectiva de las capacidades propuesta por Amartya Sen. Para ello, en primer lugar se realiza una revisión de la literatura sobre la noción de equidad y se plantea una discusión filosófica al respecto. En segundo lugar, se lleva dicha discusión hacia el ámbito de la educación. En tercer lugar, en concordancia con la aproximación de Sen, se define el concepto de equidad educativa como igualdad en los resultados en las habilidades que adquieren los individuos luego de participar en el sistema educativo (nivel medio. Finalmente, se concluye que bajo esta concepción es posible recomendar políticas para compensar las diferencias de origen.

  2. Capacidades y libertad. Una aproximación a la teoría de Amartya Sen

    Cejudo Córdoba, Rafael

    2007-08-01

    Full Text Available This paper explains Amartya Sen’s capabilities approach as a way of unifying most of his social philosophy. Capabilites are defined as the opportunities to enjoy several ways of life, and they provide the notion of aggregate welfare used in Human Development Reports of the United Nations Development Programme. Besides, capabilities approach provides a theory of liberty that I have called freedom as capability. In this way, Sen’s researches on famines and development, social choice and rights converge in a notion of freedom which is consistent with cultural differences. This concept is nor the liberal one neither the liberty as non-domination of republicanism, and Sen makes use of it in his defence of social welfare policies.

    Este artículo expone el enfoque de las capacidades de Amartya Sen como elemento unificador de buena parte de su filosofía social. Las capacidades se definen como las oportunidades para llevar una u otra clase de vida, y mediante ellas se obtiene la noción de bienestar agregado utilizada en los Informes sobre Desarrollo Humano elaborados por el Programa de las Naciones Unidas para el Desarrollo. Al mismo tiempo, el enfoque de las capacidades proporciona una teoría de la libertad, que he denominado libertad como capacidad, mediante la cual los estudios de Sen sobre el hambre y el desarrollo, la elección social o los derechos convergen en una noción de libertad que aspira a superar las diferencias culturales. Este concepto ni es el liberal ni es tampoco la libertad como no-dominación del republicanismo, y mediante él Sen defiende la importancia de las políticas de bienestar social.

    Full Text Available The study aims at collective hunger in the vision of Amartya Sen as one of the impeding factors of Sustainable Human Development. In the economist's view, collective hunger goes beyond chronic hunger, involves a sudden outbreak of deprivation for a portion of the population. To eliminate hunger in the modern world, it is crucial to understand the cause of collective hunger in a broad way, and not just because of some mechanical imbalance between food and population. By illustrating the deprivation of liberty, child labor is included as one of the impediments to sustainable human development.

    Full Text Available This paper illustrates somehow aspect of the capabilities approach developed by the economist and philosopher Amartya Sen. Particularly it examines how the concept of freedom (as “opportunity” reveals unable to empirically and normatively adjust to the notion of freedom as capability. From such categorical contradiction is introduced a set of unprecedented concepts that, gathered to the largest social dimension of freedom, allow releasing from such mismatch. Conclusions are focused on the emphasis of social environment as state that far from its recognized influence on individual capabilities has potentially enablers’ elements.En este trabajo se ilustran algunos aspectos relativos al enfoque de las capacidades desarrollado por el economista y filósofo Amartya Sen. Particularmente se examina cómo el concepto de libertad (“de oportunidad” se revela imposibilitado para atenerse empírica y normativamente a la noción de libertad como capacidad.

    The purpose of the present study was to non-invasively compare ascending aortic blood flow and cross-sectional area (CSA) variations vs time in Mustard or Senning repaired (MSR) patients against those of healthy volunteers at rest. Velocity-encoded MR imaging was performed in 10 male patients (age range 18-24 years, median age 20.5 years) late after a Mustard or Senning correction, and in 10 male healthy volunteers (age range 21-25 years, median age 22.5 years), at the upper part of the ascending aorta. Both aortic cross-sectional area (CSA) and blood-flow variations were recorded over a complete cardiac cycle, with a 30-ms time of resolution. The body-surface area (BSA), the mean CSA over the systolic phase, and the BSA-normalized systemic ventricle power and work were significantly lower in the patient series compared with those of the volunteer series. The BSA-normalized right ventricle (RV) power and work of MSR patients were equal to 87 and 83% on average of those of the left ventricle (LV) of healthy volunteers. We conclude that, at rest, the mechanical performance of the systemic RV in MSR patients is significantly lower than that of the LV in healthy volunteers. Furthermore, the significantly lower aortic CSA found in MSR patients than in healthy volunteers may reveal an increase in the vasomotor tone. (orig.)

    A new gamma-camera architecture named HiSens is presented and evaluated. It consists of a parallel hole collimator, a pixelated CdZnTe (CZT) detector associated with specific electronics for 3D localization and dedicated reconstruction algorithms. To gain in efficiency, a high aperture collimator is used. The spatial resolution is preserved thanks to accurate 3D localization of the interactions inside the detector based on a fine sampling of the CZT detector and on the depth of interaction information. The performance of this architecture is characterized using Monte Carlo simulations in both planar and tomographic modes. Detective quantum efficiency (DQE) computations are then used to optimize the collimator aperture. In planar mode, the simulations show that the fine CZT detector pixelization increases the system sensitivity by 2 compared to a standard Anger camera without loss in spatial resolution. These results are then validated against experimental data. In SPECT, Monte Carlo simulations confirm the merits of the HiSens architecture observed in planar imaging.

  8. RNA processing factors Swd2.2 and Sen1 antagonize RNA Pol III-dependent transcription and the localization of condensin at Pol III genes.

    Condensin-mediated chromosome condensation is essential for genome stability upon cell division. Genetic studies have indicated that the association of condensin with chromatin is intimately linked to gene transcription, but what transcription-associated feature(s) direct(s) the accumulation of condensin remains unclear. Here we show in fission yeast that condensin becomes strikingly enriched at RNA Pol III-transcribed genes when Swd2.2 and Sen1, two factors involved in the transcription process, are simultaneously deleted. Sen1 is an ATP-dependent helicase whose orthologue in Saccharomyces cerevisiae contributes both to terminate transcription of some RNA Pol II transcripts and to antagonize the formation of DNA:RNA hybrids in the genome. Using two independent mapping techniques, we show that DNA:RNA hybrids form in abundance at Pol III-transcribed genes in fission yeast but we demonstrate that they are unlikely to faciliate the recruitment of condensin. Instead, we show that Sen1 forms a stable and abundant complex with RNA Pol III and that Swd2.2 and Sen1 antagonize both the interaction of RNA Pol III with chromatin and RNA Pol III-dependent transcription. When Swd2.2 and Sen1 are lacking, the increased concentration of RNA Pol III and condensin at Pol III-transcribed genes is accompanied by the accumulation of topoisomerase I and II and by local nucleosome depletion, suggesting that Pol III-transcribed genes suffer topological stress. We provide evidence that this topological stress contributes to recruit and/or stabilize condensin at Pol III-transcribed genes in the absence of Swd2.2 and Sen1. Our data challenge the idea that a processive RNA polymerase hinders the binding of condensin and suggest that transcription-associated topological stress could in some circumstances facilitate the association of condensin.

    Full Text Available Abstract Background Uncomplicated urinary tract infections (UTI are a frequent reason for consultation of women in primary health care. To avoid therapy failure and development of resistances, the choice of an antibiotic should be based on the knowledge of recent local resistance data but these data are scarce for the Austrian primary health care sector. Within the context of the ECO·SENS II study it was the aim to obtain appropriate and relevant local resistance data and describe the changes in the resistance pattern in comparison to the ECO·SENS study. Methods 23 GPs from different parts of Austria participated in the study between July 2007 and November 2008. According to the defined inclusion- and exclusion criteria female patients with symptoms of an uncomplicated UTI were included and a midstream urine sample was collected. In case of significant bacteriuria susceptibility testing of E. coli against 14 antibiotics was performed. Descriptive statistical methods were used. Results In 313 patients included in the study, a total of 147 E. coli isolates (47% were detected and tested. The resistance rates were in %: Mecillinam (0.0, nitrofurantoin (0.7, fosfomycin trometamol (0.7, gentamycin (1.4, cefotaxime (2.7, ceftazidime (2.7, Cephadroxil (4.1 and ciprofloxacin (4.1.

Additionally, the comparison of these results with the results of the ECO·SENS study demonstrated an increase in resistance rates of ampicillin, amoxicillin/clavulanic acid, nalidixic acid and ciprofloxacin. Conclusions The resistance data for E. coli in uncomplicated UTIs in women gained by this study are the most recent data for this disease in Austria at the moment.

    Restrepo-Ochoa, Diego Alveiro

    2013-12-01

    The aim of this article is to analyze the contribution by Amartya Sen's capability approach to ethical reasoning in public health. Based on critiques by the capability approach towards utilitarianism, the article proposes a concept of health based on four characteristics: a pluralistic notion of good life, expansion of freedom as the ethical foundation for health actions, a concept of person as agent, and recognition of the inner view of health based on positional objectivity. The contribution by the capability approach to ethical reasoning in public health can be summarized in four points: insufficiency of healthcare as a criterion for individual advantage, health equity as a part of social justice, the relevance of individual self-rated health, and the development of capability as an ultimate goal of public policies in public health.

    2007-05-01

    Full Text Available ResumoNo estudo das intervenções de desenvolvimento, Amartya Sen traz uma contribuição relevante, ao analisar que elas são construídas, de acordo com referenciais filosóficos e políticos, quais sejam ligados ao Utilitarismo, ao Libertarismo ou a Geração de Liberdades Substantivas. Segundo Sen, o Utilitarismo apresenta sua proposta de intervenção a partir da utilidade de ações e de regras propostas, sendo o foco principal a inovação; quanto ao Libertarismo, ele admite a igualdade formal de oportunidades, sendo que, para a sua concretização, há necessidade de se estabelecer o acesso dos cidadãos aos setores básicos de saúde, educação, infra-estrutura, saneamento, dentre outros; já a referência de Geração de Liberdades Substantivas evidencia que, para fins de intervenção, o espaço apropriado não seria essencialmente o das utilidades, nem tampouco o da provisão de bens primários, mas no sentido de gerar a capacidade e a oportunidade real para os indivíduos proverem seus objetivos após o término da intervenção. Assim, delimita-se uma análise para a tradução dos fundamentos das intervenções em termos operacionais, no que diz respeito, especificamente, aos objetivos, metas e estratégias. Foram estudadas cento e vinte e seis intervenções de desenvolvimento rural, dentre políticas, programas e projetos, com foco na melhoria das condições de vida das populações e na conservação dos recursos naturais, evidenciando o Estado do Pará como locus de estudo entre 1996-2005. Esta análise demonstra que, embora quase todas as intervenções tenham sido delineadas sob o pressuposto de desenvolvimento, a maior parte delas não apresenta referencial adequado para sua efetividade.

    2017-03-01

    Full Text Available The aim of this study is estimation of social welfare in Russian regions in 2004-2014 based on the A. Sen abbreviated function, the assessment of regions convergence in welfare and factors contributing to it. We adjusted the A. Sen welfare function by the cost of living in regions and presented it as a four-factor multiplicative model. By use of the coefficient of variation (CV we estimated the inter-regional inequality in welfare in statics and dynamics. The technique of decomposition of the squared CV for logarithm of welfare function enabled us to evaluate the contribution of main and intersect factors to Russian regions' convergence in welfare. As a result we assessed Russian regions social welfare in dynamics and evaluated factors contributing to its growth. Based on the weighted CV we discovered the negative impact of the recession of 2009 on the regions convergence in welfare, and unweighted CV even more revealed the turning point in the convergence tendency occurring in 2012. We discovered that in statics the redistributive factor makes the greatest and increasing contribution to inter-regional convergence in welfare, whilst the cost of living and intraregional income inequality factors have moderate and decreasing influence on it. The dynamic analysis revealed two factors predominantly contributing to regions' temporal convergence in welfare, namely growing convergence in GRP per capita and significant but unstable influence of distributive factor. Two other factors, the cost of living and intra-regional income inequality, counteracted to temporal convergence mainly due to attenuation of their negative correlation to nominal and real income per capita respectively. The results obtained may be applicable to both inter-budgetary and regional policy development.

    2014-01-01

    Full Text Available Este trabajo parte del concepto de “capacidad” de Sen, definido como un aspecto de la libertad que requiere de oportunidades sustantivas, para aproximarse al término de capacidad política. La capacidad política, por tanto, es un aspecto de la libertad que comprende oportunidades de participación política sustantiva. Esta aproximación a la capacidad política está confrontada con dos corrientes del pensamiento: el institucionalismo trascendental o contractualismo y el comparativista. Considerando estas dos corrientes de pensamiento, los conceptos institucionales de ciudadanía activa y sociedad civil, promovidos en las últimas décadas por gobiernos neoliberales, son examinados de forma crítica. Asimismo, se relaciona la capacidad política con modelos teóricos clásicos de sociedad civil. Esta relación entre la capacidad política con los conceptos de ciudadanía y sociedad civil ayudan a barajar la hipótesis de que se privilegia en política el consenso por mayoría (enfoque trascendental o contractualista, frente al consenso por discusión (enfoque comparativista o consecuencialista. La tradición contractualista dificultaría el reconocimiento del enfoque comparativista, fundamentado en la idea de equidad de Sen, y esencial para un gobierno por discusión, limitando así la capacidad política.

    Emotion perception deficits could be due to disrupted connectivity of key nodes in the salience and emotion network (SEN), including the amygdala, subgenual anterior cingulate cortex (sgACC), and insula. We examined SEN resting-state (rs-)fMRI connectivity in rMDD in relation to Facial Emotion Perception Test (FEPT) performance. Fifty-two medication-free people ages 18 to 23 years participated. Twenty-seven had major depressive disorder (MDD) in remission (rMDD, 10 males), as MDD is associated with emotion perception deficits and alterations in rsfMRI. Twenty-five healthy controls (10 males) also participated. Participants completed the FEPT during fMRI, in addition to an 8-minute eyes-open resting-state scan. Seed regions of interest were defined in the amygdala, anterior insula and sgACC. Multiple regression analyses co-varied diagnostic group, sex and movement parameters. Emotion perception accuracy was positively associated with connectivity between amygdala seeds and regions primarily in the SEN and cognitive control network (CCN), and also the default mode network (DMN). Accuracy was also positively associated with connectivity between the sgACC seeds and other SEN regions, and the DMN, particularly for the right sgACC. Connectivity negatively associated with emotion perception was mostly with regions outside of these three networks, other than the left insula and part of the DMN. This study is the first to our knowledge to demonstrate relationships between facial emotion processing and resting-state connectivity with SEN nodes and between SEN nodes and regions located within other neural networks.

It is problematized the political links with the market economy, to the extent that they have generated and instructed us to manage our own self-image. Thus, productivity is revealed a strong amalgam of generators and sense of body and reality. Through analysis of advertisements and television programs available on the Internet, advertisements distance courses distributed by e-mail, as well as an art project also published on the network, we come to the evidence that the image today has become the commodity par excellence. She does not just sell a product or herself, sells an experience of a world to 'my own'.

    It has been suggested that, in HIV-HCV co-infected patients, co-infections with other viruses may affect the response to HCV therapy. We aimed to assess the prevalence of GBV-C, SEN-V and occult HBV infections, their impact on HCV and HIV infections and on the response to HCV therapy in HIV-HCV co-infected patients. Three-hundred and sixty eight patients were tested before starting interferon-ribavirin for the presence of occult hepatitis B DNA, GBV-C RNA and SEN-V DNA by using real time PCR. Clinical, immunological, virological, histological characteristics and response to HCV therapy were compared according to the presence or not of each viral co-infection. HBV DNA, GBV-C RNA and SEN-V DNA were found in 5 (1.4%, CI95%: 0.2-2.4%), 104 (29.9%, CI95%: 25.1-34.7%) and 209 patients (57.9%, CI95%: 52.8-63.0%), respectively. GBV-C positive patients had significantly higher CD4 count at baseline, during and after HCV therapy, even after stratification on antiretroviral treatment. No other significant difference was observed according to the presence or not of GBV-C or SEN-V co-infection, in particular regarding virological responses to HCV combination therapy. There is no reason to withhold HCV therapy in HIV infected patients who have access to HAART, because of occult HBV, GBV-C or SEN-V co-infections.

    This study examined the altered patterns of functional connectivity in task-positive resting state networks in failed back surgery syndrome (FBSS) patients compared to healthy controls using functional magnetic resonance imaging (fMRI). This work stems from a previous study in which alterations in the task-negative default mode network were investigated. Participants underwent a 7-minute resting state fMRI scan in which they lay still, with eyes closed, in the absence of a task. Scanning took place at the National Research Council's 3Tesla MRI magnet in Winnipeg, Canada. Fourteen patients with FBSS and age- and gender-matched controls participated in this study. Three patients were removed from the analyses due to image artefact (n=1) and effective pain treatment (n=2). Eleven patients (5 female, mean age 52.7 years) and their matched controls were included in the final analyses. Resting state fMRI data were analyzed using an independent component analysis, yielding three resting state networks of interest: the salience network (SN), involved in detection of external stimuli, central executive network (CEN), involved in cognitions, and sensorimotor network (SeN), involved in sensory and motor integration. Analysis of Variance contrasts were performed for each network, comparing functional connectivity differences between FBSS patients and healthy controls. Alterations were observed in all three resting state networks, primarily relating to pain and its processing in the FBSS group. Specifically, compared to healthy controls, FBSS patients demonstrated increased functional connectivity in the anterior cingulate cortex within the SN, medial frontal gyrus in the CEN, and precentral gyrus within the SeN. FBSS patients also demonstrated decreased functional connectivity in the medial frontal gyrus in the SeN compared to healthy controls. Interestingly, we also observed internetwork functional connectivity in the SN and SeN. FBSS is associated with altered patterns of

    Full Text Available O presente artigo trata do deslocamento apontado por Merleau-Ponty do campo da razão para os caminhos do sensível através do olhar míope do personagem Minguilim, da novela “Campo Geral”, de João Guimarães Rosa. Usando como fio condutor a deficiência visual da personagem principal vamos acompanhá-lo na transição do mundo infantil para o mundo adulto. Nesse percurso do microsaber (olhar das miudezas para o macrosaber (o olhar turvo, Minguilim encontra passagens através de adultos como o alegre seu Aristeu e a contadora de histórias Siàrlinda ou do discurso do irmão Dito, que consegue conversar com os mais velhos. Em oposição ao “falar”, Minguilim desenvolve o “olhar” numa percepção do mundo que passa pela observação do detalhe. Sua mirada, que entrega ao leitor uma lupa, limita a sua visão para fora, mas a expande para dentro retornando à camada do sensível e encontrando o poder poético. Há duas travessias no texto: o luto pela perda do irmão Dito e a descoberta da beleza de Mutum através do uso dos óculos, emprestados por um estranho. É por meio de dicotomias básicas entre as cores e o negro, o perto e o longe, o visto e o não visto, a fé e o luto, o lúdico e o real que o menino realiza os seus primeiros questionamentos e a sua entrada ao universo dos adultos. Miguilim vai encontrar as respostas ao enfrentar o pai e a doença e pelo alargamento da visão e da linguagem proposto com maestria por Guimarães Rosa.

    Biondo, Francesco

    2010-06-01

    Full Text Available In this paper I try to revise Sen’s thesis about the «transcendental» nature of Rawls’ theory of justice. According to Sen transcendental theories of justice are unnecessary. What we aim at is to justify a series of comparative judgements about two or more states of affairs.We do not strive, unlike Rawls, to form a complete system of moral principles that backs an «ideal just society». I try to show that Sen’s «comparative» account is weak. First of all, Sen does not offer a fair interpretation of Rawls’ theory. In particular, he is wrong when he depicts Rawls’ justice as fairness as a complete and transcendental moral doctrine. Secondly, Sen overlooks the fact that in order to justify comparative evaluations of states of affairs we must assume as valid a particular moral doctrine. Finally I try to solve the problem about the contrast between transcendental and comparative account by offering a transcendental outlook to questions of justice that is, at the same time, pluralist and incomplete.

    En este trabajo intento exponer las tesis de Sen sobre las características que demandamos a una teoría satisfactoria de la justicia, y sus críticas al modelo «trascendental» de teoría, que según él es lo que Rawls persigue. Según Sen, este modelo es inaceptable por ser inalcanzable e innecesario; lo que en nuestra práctica argumentativa intentamos lograr son juicios comparativos entre situaciones reales, y no sistemas completos de proposiciones acerca de ideales de la sociedad justa. Intentaré argumentar que el enfoque metaético de Sen es débil por dos razones: no ofrece una reconstrucción adecuada de la teoría de Rawls, equivocándose sobre su carácter «completo», y no explica de qué manera los juicios comparativos de valor entre dos situaciones sociales no sean el resultado de una teoría «trascendental» de la justicia. Me propongo, entonces, solucionar el problema, presentando una mirada trascendental de las

    We experimentally investigated the fluid warming performances of three warmers with different technology, according to flow rates and distances. We used the following intravenous fluid warmers: Mega Acer Kit (Group M, n = 8), Ranger (group R, n = 8), and ThermoSens (group T, n = 8). Fluids that had been stored in the operating room over the previous 24 h were delivered at sequent flow rates of from 440 mL/h up to 2500 mL/h through preheated warming devices. The fluid temperatures were recorded at the inlet point, 76-cm proximal (Pout1) and 166-cm distal outlet points (Pout2) every 1 min for 10 min. We repeated each test eight times. The delivered fluid temperature [mean (95% confidence interval)] was significantly higher in group M than group R and T at flow rates up to 650 mL/h with the highest value at 440 mL/h [34.30 (33.35-35.24)°C] (P flow rates over 1140 mL/h at Pout1 [36.67 (36.62-36.73)°C and 37.85 (37.52-38.17)°C at 2500 mL/h, respectively] (P flow rates for each device (P flow rates. Furthermore, the device performance is more effective with shorter extension lines.

  15. Science, Technology and Innovation as Social Goods for Development: Rethinking Research Capacity Building from Sen's Capabilities Approach.

    Science.gov (United States)

    Mormina, Maru

    2018-03-01

    Science and technology are key to economic and social development, yet the capacity for scientific innovation remains globally unequally distributed. Although a priority for development cooperation, building or developing research capacity is often reduced in practice to promoting knowledge transfers, for example through North-South partnerships. Research capacity building/development tends to focus on developing scientists' technical competencies through training, without parallel investments to develop and sustain the socioeconomic and political structures that facilitate knowledge creation. This, the paper argues, significantly contributes to the scientific divide between developed and developing countries more than any skills shortage. Using Charles Taylor's concept of irreducibly social goods, the paper extends Sen's Capabilities Approach beyond its traditional focus on individual entitlements to present a view of scientific knowledge as a social good and the capability to produce it as a social capability. Expanding this capability requires going beyond current fragmented approaches to research capacity building to holistically strengthen the different social, political and economic structures that make up a nation's innovation system. This has implications for the interpretation of human rights instruments beyond their current focus on access to knowledge and for focusing science policy and global research partnerships to design approaches to capacity building/development beyond individual training/skills building.

    Recent changes in regulatory requirements and social views on animal testing have accelerated the development of reliable alternative tests for predicting skin sensitizing potential of chemicals. In this study, we aimed to develop a new in vitro skin sensitization assay using reconstructed human epidermis, RhE model, which is expected to have broader applicability domain rather than existing in vitro assays. Microarray analysis revealed that the expression of five genes (ATF3, DNAJB4, GCLM, HSPA6 and HSPH1) related to cellular stress response were significantly up-regulated in RhE model after 6h treatment with representative skin sensitizers, 1-fluoro-2,4-dinitrobenzene and oxazolone, but not a non-sensitizer, benzalkonium chloride. The predictive performance of five genes was examined with eight skin sensitizers (e.g., cinnamic aldehyde), four non-sensitizers (e.g., sodium lauryl sulfate) and four pre-/pro-haptens (e.g., p-phenylenediamine, isoeugenol). When the positive criteria were set to obtain the highest accuracy with the animal testing (LLNA), ATF3, DNAJB4 and GCLM exhibited a high predictive accuracy (100%, 93.8% and 87.5%, respectively). All tested pre-/pro-haptens were correctly predicted by both ATF3 and DNAJB4. These results suggested that the RhE-based assay, termed epidermal sensitization assay (EpiSensA), could be an useful skin sensitization assay with a broad applicability domain including pre-/pro-haptens.

    We analysed nationwide early and late results after the Mustard, Senning and arterial switch operation. We included all paediatric patients (switch operation for transposition of the great arteries from 1968 to 2009 in Finland. Data were obtained retrospectively from a paediatric cardiac surgical database and population data from the Finnish national registry. Early mortality (switch patients (P switch operation, Mustard and Senning were 97% (95% CI 95-100%), 78% (95% CI 68-87%) and 84% (95% CI 77-90%), respectively. No late sudden deaths or fatal heart failures occurred after the arterial switch operation. Outcome after surgery for transposition of the great arteries has improved, mostly due to the arterial switch operation but also due to improvements in perioperative care and follow-up. Operative deaths after the arterial switch operation have diminished, and no late sudden deaths or fatal heart failures occurred during the first 25-30 years after the procedure.

    Full Text Available The aim of this paper is to analyze, from a sociological viewpoint, the theoretical and methodological challenges posed by Amartya Sen in his textbook Development as Freedom. The concept of freedom, according with Sen, includes what he calls the «opportunity aspect» and the «process aspect» of freedom. My argument is that the human development paradigm has been more focused in exploring the former than the latter, ignoring the relational dimension of human agency. In order to extend the reach of the capability approach in this direction, I propose to accept three complementary premises: 1 that freedom is a social relationship; 2 that the fights for equality are always constrained by power relations; 3 that the agents in these scenarios are collective actors, rather than individuals.

    Constructing coexpression networks and performing network analysis using large-scale gene expression data sets is an effective way to uncover new biological knowledge; however, the methods used for gene association in constructing these coexpression networks have not been thoroughly evaluated. Since different methods lead to structurally different coexpression networks and provide different information, selecting the optimal gene association method is critical. In this study, we compared eight gene association methods - Spearman rank correlation, Weighted Rank Correlation, Kendall, Hoeffding's D measure, Theil-Sen, Rank Theil-Sen, Distance Covariance, and Pearson - and focused on their true knowledge discovery rates in associating pathway genes and construction coordination networks of regulatory genes. We also examined the behaviors of different methods to microarray data with different properties, and whether the biological processes affect the efficiency of different methods. We found that the Spearman, Hoeffding and Kendall methods are effective in identifying coexpressed pathway genes, whereas the Theil-sen, Rank Theil-Sen, Spearman, and Weighted Rank methods perform well in identifying coordinated transcription factors that control the same biological processes and traits. Surprisingly, the widely used Pearson method is generally less efficient, and so is the Distance Covariance method that can find gene pairs of multiple relationships. Some analyses we did clearly show Pearson and Distance Covariance methods have distinct behaviors as compared to all other six methods. The efficiencies of different methods vary with the data properties to some degree and are largely contingent upon the biological processes, which necessitates the pre-analysis to identify the best performing method for gene association and coexpression network construction.

    Directory of Open Access Journals (Sweden)

    Pedro Augusto Gravatá Nicoli

    2015-04-01

    Full Text Available This paper promotes a comparison between Amartya Sen’s Idea of Justice and the masterpiece Great Expectations of English novelist Charles Dickens, published in 1860, shedding light on proximities and counterpoints between the theory of Sen and the experience of Dickens’ characters. This correlation departs from the epigraph of Sen’s work, which evokes the injustices experienced by the protagonist Pip in Great Expectations, opening a project of justice. For this purpose, the structural dimensions of Sen’s theory of justice will be revisited, as a concrete project for removal of injustices on the lines of rational argumentation and the theory of social choice, opposed to transcendent theories. In its turn, the universe of the boy Pip of Great Expectations reveals the complex path from childhood innocence to obsession and snobbery, with hopes and frustrations built in the backdrop of Victorian England, with the deep wound of poverty and inequality as a legacy of Industrial Revolution. Dickens, in this sense, is at once a sharp critic of his time, engaging in social transformation, and a master in exploring the psychological dynamics of human relationships. Hence, the authors become close on the poignant portrayal of injustice, demanding maximum and immediate removal. They are perhaps apart on the invitation to reflect abstractly on justice and ethics in itself, as well as on the weight given to the institutions. In any case, to reflect over justice in this shared space, in which the evocative power and communicative reach of ideas are expanded, becomes an enriching exercise in all senses.

  5. Control of CydB and GltA1 expression by the SenX3 RegX3 two component regulatory system of Mycobacterium tuberculosis.

    Directory of Open Access Journals (Sweden)

    Gretta Roberts

    Full Text Available Two component regulatory systems are used widely by bacteria to coordinate changes in global gene expression profiles in response to environmental signals. The SenX3-RegX3 two component system of Mycobacterium tuberculosis has previously been shown to play a role in virulence and phosphate-responsive control of gene expression. We demonstrate that expression of SenX3-RegX3 is controlled in response to growth conditions, although the absolute changes are small. Global gene expression profiling of a RegX3 deletion strain and wild-type strain in different culture conditions (static, microaerobic, anaerobic, as well as in an over-expressing strain identified a number of genes with changed expression patterns. Among those were genes previously identified as differentially regulated in aerobic culture, including ald (encoding alanine dehydrogenase cyd,encoding a subunit of the cytochrome D ubiquinol oxidase, and gltA1, encoding a citrate synthase. Promoter activity in the upstream regions of both cydB and gltA1 was altered in the RegX3 deletion strain. DNA-binding assays confirmed that RegX3 binds to the promoter regions of ald, cydB and gltA1 in a phosphorylation-dependent manner. Taken together these data suggest a direct role for the SenX-RegX3 system in modulating expression of aerobic respiration, in addition to its role during phosphate limitation.

    Full Text Available We propose a comprehensive sensing platform called SenStick, which is composed of hardware (ultra tiny all-in-one sensor board, software (iOS, Android, and PC, and 3D case data. The platform aims to allow all the researchers to start IoT research, such as activity recognition and context estimation, easily and efficiently. The most important contribution is the hardware that we have designed. Various sensors often used for research are embedded in an ultra tiny board with the size of 50 mm (W × 10 mm (H × 5 mm (D and weight around 3 g including a battery. Concretely, the following sensors are embedded on this board: acceleration, gyro, magnetic, light, UV, temperature, humidity, and pressure. In addition, this board has BLE (Bluetooth low energy connectivity and capability of a rechargeable battery. By using 110 mAh battery, it can run more than 15 hours. The most different point from other similar boards is that our board has a large flash memory for logging all the data without a smartphone. By using SenStick, all the users can collect various data easily and focus on IoT data analytics. In this paper, we introduce SenStick platform and some case studies. Through the user study, we confirmed the usefulness of our proposed platform.

    Full Text Available De nos jours en Russie, parmi les diverses interprétations du passé soviétique, une portion de la population tend à réactualiser la mise en valeur des réalisations technologiques, scientifiques et politiques du régime stalinien. Dans cette optique, l’histoire des répressions est préférablement mise de côté ou son importance minimisée. L’oubli est une menace constante pour les survivants des répressions mais plusieurs espèrent, malgré la diminution de l’intérêt manifesté par le public, obtenir une place dans le récit historique collectif. Certaines victimes font face à l’oubli et cherchent à donner un sens à leur expérience tragique par le biais de la narration. Lorsque ces dernières disparaissent, ce sont parfois leurs descendants qui poursuivent le travail de mémoire. La fille d’un intellectuel kazakh réprimé dans les années 1930, Larissa Kouderina, tente de rétablir la vérité sur le passé de sa famille. Elle souhaite également, dans une perspective plus vaste, faire reconnaître l’histoire de tout un groupe d’intellectuels kazakhs du début du XXe siècle. Pour réaliser ses objectifs, elle a d’abord publié les mémoires de sa mère ainsi qu’un essai qu’elle a rédigé sur l’histoire de son père et de la « première intelligentsia » à laquelle il appartenait. Depuis, elle prépare et espère un jour ouvrir un petit musée dédié à cette dernière. Ses publications et son musée constituent, dans ma perspective de recherche, les composantes d’un projet de commémoration. Ce projet est en quelque sorte une mission qu’elle s’est donnée, qui donne sens à sa vie et qui contribue à la construction de son identité. Dans cet article, j’observe comment les discours de l’histoire et de la mémoire sont conjugués à l’intérieur de son projet et comment elle s’est constituée en porte-parole non seulement de sa famille mais aussi d’une génération intellectuelle.

    In Parkinson's disease (PD), the relation between cortical brain atrophy on MRI and clinical progression is not straightforward. Determination of changes in structural covariance networks - patterns of covariance in grey matter density - has shown to be a valuable technique to detect subtle grey matter variations. We evaluated how structural network integrity in PD is related to clinical data. 3 Tesla MRI was performed in 159 PD patients. We used nine standardized structural covariance networks identified in 370 healthy subjects as a template in the analysis of the PD data. Clinical assessment comprised motor features (Movement Disorder Society-Unified Parkinson's Disease Rating Scale; MDS-UPDRS motor scale) and predominantly non-dopaminergic features (SEverity of Non-dopaminergic Symptoms in Parkinson's Disease; SENS-PD scale: postural instability and gait difficulty, psychotic symptoms, excessive daytime sleepiness, autonomic dysfunction, cognitive impairment and depressive symptoms). Voxel-based analyses were performed within networks significantly associated with PD. The anterior and posterior cingulate network showed decreased integrity, associated with the SENS-PD score, p = 0.001 (β = - 0.265, ηp2 = 0.070) and p = 0.001 (β = - 0.264, ηp2 = 0.074), respectively. Of the components of the SENS-PD score, cognitive impairment and excessive daytime sleepiness were associated with atrophy within both networks. We identified loss of integrity and atrophy in the anterior and posterior cingulate networks in PD patients. Abnormalities of both networks were associated with predominantly non-dopaminergic features, specifically cognition and excessive daytime sleepiness. Our findings suggest that (components of) the cingulate networks display a specific vulnerability to the pathobiology of PD and may operate as interfaces between networks involved in cognition and alertness.

    Visual dysfunction is more common in children with neurological impairments and previous studies have recommended such children receive visual and refractive assessment. In the UK, children with neurological impairment often have educational statementing for Special Educational Needs (SEN) and the statement should detail all health care and support needs to ensure the child's needs are met during school life. This study examined the representation of visual information in statements of SEN and compared this to orthoptic visual information from school visual assessments for children in a special school in Northern Ireland, UK. The parents of 115 school children in a special school were informed about the study via written information. Participation involved parents permitting the researchers to access their child's SEN educational statement and orthoptic clinical records. Statement information was accessed for 28 participants aged between four and 19 years; 25 contained visual information. Two participants were identified in their statements as having a certification of visual impairment. An additional 10 children had visual acuity ≥ 0.3 logMAR. This visual deficit was not reported in statements in eight out of these 12 cases (67%). 11 participants had significant refractive error and wore spectacles, but only five (45%) had this requirement recorded in their statement. Overall, 10 participants (55%) had either reduced visual acuity or significant refractive error which was not recorded in their statement. Despite additional visual needs being common, and described in clinical records, the majority of those with reduced vision and/or spectacle requirements did not have this information included in their statement. If visual limitations are not recognized by educational services, the child's needs may not be met during school life. More comprehensive eye care services, embedded with stakeholder communication and links to education are necessary to improve

    The level of arterial carbon dioxide partial tension (PaCO2) is a sine qua non for the determination of the adequacy of ventilation. The aim of this study was to assess the usefulness of SenTec Digital Monitor System in measuring transcutaneous arterial carbon dioxide partial tension (PCO2) non-invasively for the management of chronic respiratory failure. Three ICU patients suffering from chronic respiratory failure were enrolled. We recorded the data of PCO2 measured by a transcutaneous ear sensor (V-Sign : SenTec Inc.) and the data of PaCO2 (GASTAT-603ie Techno Medica Co., Ltd., Japan) obtained from arterial blood gas analysis. The mean PCO2 was 67.2 mmHg (min. 65.9 mmHg, max. 80.2 mmHg, n = 10), and the mean PaCO2 was 71.2 mmHg (min. 67.2 mmHg, max. 79.0 mmHg, n = 10). Regression analysis showed good correlation between PCO2 and PaCO2 (PCO2 = .95 x PaCO2-0.18 mmHg; R = 0.74). Bland-Altman analysis of PCO2 yields a bias of d = 3.9 mmHg with limits of agreement (1SD) -0.4 mmHg, +8.2 mmHg. SenTec Digital Monitor System enables non-invasive and reliable trend monitoring of PCO2 levels in patients with chronic respiratory failure.

    An accurate accessible test for early infant diagnosis (EID) is crucial for identifying HIV-infected infants and linking them to treatment. To improve EID services in Ukraine, dried blood spot (DBS) samples obtained from 237 HIV-exposed children (≤18 months of age) in six regions in Ukraine in 2012 to 2013 were tested with the AmpliSens DNA-HIV-FRT assay, the Roche COBAS AmpliPrep/COBAS TaqMan (CAP/CTM) HIV-1 Qual test, and the Abbott RealTime HIV-1 Qualitative assay. In comparison with the paired whole-blood results generated from AmpliSens testing at the oblast HIV reference laboratories in Ukraine, the sensitivity was 0.99 (95% confidence interval [CI], 0.95 to 1.00) for the AmpliSens and Roche CAP/CTM Qual assays and 0.96 (95% CI, 0.90 to 0.98) for the Abbott Qualitative assay. The specificity was 1.00 (95% CI, 0.97 to 1.00) for the AmpliSens and Abbott Qualitative assays and 0.99 (95% CI, 0.96 to 1.00) for the Roche CAP/CTM Qual assay. McNemar analysis indicated that the proportions of positive results for the tests were not significantly different (P > 0.05). Cohen's kappa (0.97 to 0.99) indicated almost perfect agreement among the three tests. These results indicated that the AmpliSens DBS and whole-blood tests performed equally well and were comparable to the two commercially available EID tests. More importantly, the performance characteristics of the AmpliSens DBS test meets the World Health Organization EID test requirements; implementing AmpliSens DBS testing might improve EID services in resource-limited settings.

    Full Text Available Nucleic acid amplification tests are increasingly used for the rapid diagnosis of tuberculosis. We undertook a comparative study of the efficiency and diagnostic yield of a real-time PCR senX3-regX3 based assay versus the classical IS6110 target and the new commercial methods.This single-blind prospective comparative study included 145 consecutive samples: 76 from patients with culture-confirmed tuberculosis (86.8% pulmonary and 13.2% extrapulmonary tuberculosis: 48.7% smear-positive and 51.3% smear-negative and 69 control samples (24 from patients diagnosed with non-tuberculous mycobacteria infections and 45 from patients with suspected tuberculosis which was eventually ruled out. All samples were tested by two CE-marked assays (Xpert®MTB/RIF and AnyplexTM plus MTB/NTM and two in-house assays targeting senX3-regX3 and the IS6110 gene.The detection limit ranged from 1.00E+01 fg for Anyplex, senX3-regX3 and IS6110 to 1.00E+04 fg for Xpert. All three Xpert, senX3-regX3 and IS6110 assays detected all 37 smear-positive cases. Conversely, Anyplex was positive in 34 (91.9% smear-positive cases. In patients with smear-negative tuberculosis, differences were observed between the assays; Xpert detected 22 (56.41% of the 39 smear-negative samples, Anyplex 24 (61.53%, senX3-regX3 28 (71.79% and IS6110 35 (89.74%. Xpert and senX3-regX3 were negative in all control samples; however, the false positive rate was 8.7% and 13% for Anyplex and IS6110, respectively. The overall sensitivity was 77.6%, 85.7%, 77.3% and 94.7% and the specificity was 100%, 100%, 90.8% and 87.0% for the Xpert, senX3-regX3, Anyplex and IS6110 assays, respectively.Real-time PCR assays targeting IS6110 lack the desired specificity. The Xpert MTB/RIF and in-house senX3-regX3 assays are both sensitive and specific for the detection of MTBC in both pulmonary and extrapulmonary samples. Therefore, the real time PCR senX3-regX3 based assay could be a useful and complementary tool in the

    During the last 20 years, molecular biology techniques have propelled the diagnosis of parasitic diseases into a new era, as regards assay speed, sensitivity, and parasite characterization. However, DNA extraction remains a critical step and should be adapted for diagnostic and epidemiological studies. The aim of this report was to document the constraints associated with DNA extraction for the diagnosis of parasitic diseases and illustrate the adaptation of an automated extraction system, NucliSENS easyMAG, to these constraints, with a critical analysis of system performance. Proteinase K digestion of samples is unnecessary with the exception of solid tissue preparation. Mechanically grinding samples prior to cell lysis enhances the DNA extraction rate of fungal cells. The effect of host-derived nucleic acids on the extraction efficiency of parasite DNA varies with sample host cell density. The optimal cell number for precise parasite quantification ranges from 10 to 100,000 cells. Using the NucliSENS easyMAG technique, the co-extraction of inhibitors is reduced, with an exception for whole blood, which requires supplementary extraction steps to eliminate inhibitors. © F.

    2011-10-01

    Full Text Available RNA polymerase II synthesizes a diverse set of transcripts including both protein-coding and non-coding RNAs. One major difference between these two classes of transcripts is the mechanism of termination. Messenger RNA transcripts terminate downstream of the coding region in a process that is coupled to cleavage and polyadenylation reactions. Non-coding transcripts like Saccharomyces cerevisiae snoRNAs terminate in a process that requires the RNA-binding proteins Nrd1, Nab3, and Sen1. We report here the transcriptome-wide distribution of these termination factors. These data sets derived from in vivo protein-RNA cross-linking provide high-resolution definition of non-poly(A terminators, identify novel genes regulated by attenuation of nascent transcripts close to the promoter, and demonstrate the widespread occurrence of Nrd1-bound 3' antisense transcripts on genes that are poorly expressed. In addition, we show that Sen1 does not cross-link efficiently to many expected non-coding RNAs but does cross-link to the 3' end of most pre-mRNA transcripts, suggesting an extensive role in mRNA 3' end formation and/or termination.

Au long de son commentaire sur Hobbes, Schmitt aboutit toutefois à un résultat inattendu. Naguère loué comme « le cas classique de la pensée décisionniste », Hobbes s’est métamorphosé à son insu en « ancêtre spirituel » de l’État législateur et libéral-constitutionnel. Schmitt a trouvé chez son allié le plus précieux les germes d’une pensée qu’il n’a cessé d’éreinter sous toutes ses formes, qu’on la décline dans sa version techniciste, positiviste, constitutionnaliste bourgeoise et libérale, individualiste ou pluraliste. C’est en ce sens que le Der Leviathan résume à bien des égards le sens et l’échec du décisionnisme politique.

    In Mustard/Senning-repaired (MSR) patients, the right and left ventricles (RV, LV) act as the systemic and pulmonary ventricle, respectively. The purpose of the study was to compare non-invasively, at rest, pulmonary ventricle systolic function and hemodynamics in MSR patients with those of healthy volunteers. Velocity-encoded MR imaging was performed at the level of the main pulmonary artery (MPA) in ten male patients late after a Mustard/Senning correction performed early in infancy and in ten male volunteers. Both blood flow and MPA cross-sectional area variations were recorded over a complete cardiac cycle. MPA distensibility, body surface area (BSA)-normalized pulmonary ventricle systolic power and work were significantly lower in the MSR patients compared to volunteers. In particular, BSA-normalized LV systolic power and work in MSR patients were equal to 82 and 77% on average of those of the RV in volunteers (0.32 vs. 0.39 W/m{sup 2} and 0.10 vs. 0.13 J/m{sup 2}), respectively. We conclude that in MSR patients at rest two unrelated findings were observed: (1) a reduced MPA distensibility and (2) a significantly lower systolic mechanical performance of the pulmonary LV compared to that of the RV in healthy volunteers. The latter quantification indirectly confirms the lowest systemic RV systolic mechanical performance previously published. (orig.)

    Staphylococcal enterotoxins (SEs) produced by Staphylococcus aureus are the most recognizable causative agents of emetic food poisoning in humans. New types of SEs and SE-like (SEl) toxins have been reported. Several epidemiological investigations have shown that the SEs and SEl genes, particularly, SEK, SEL, SEM, SEN and SEO genes, are frequently detected in strains isolated from patients with food poisoning. The purpose of the present study was to evaluate the emetic activity of recently identified SEs using a small emetic animal model, the house musk shrew. The emetic activity of these SEs in house musk shrews was evaluated by intraperitoneal administration and emetic responses, including the number of shrews that vomited, emetic frequency and latency of vomiting were documented. It was found that SEs induce emetic responses in these animals. This is the first time to demonstrate that SEK, SEL, SEM, SEN and SEO possess emetic activity in the house musk shrew. © 2017 The Societies and John Wiley & Sons Australia, Ltd.

    Crack growth direction has been studied in many ways. Particularly Sih's strain energy theory predicts that a fracture under a three-dimensional state of stress spreads in direction of the minimum strain energy density. In this work a study for angle of fracture growth was made, considering a biaxial stress state at the crack tip on SEN specimens. The stress state applied on a tension-compression SEN specimen is biaxial one on crack tip, as it can observed in figure 1. A solution method proposed to obtain a mathematical model considering genetic algorithms, which have demonstrated great capacity for the solution of many engineering problems. From the model given by Sih one can deduce the density of strain energy stored for unit of volume at the crack tip as dW = [1/2E({sigma}{sup 2}{sub x} + {sigma}{sup 2}{sub y}) - {nu}/E({sigma}{sub x}{sigma}{sub y})]dV (1). From equation (1) a mathematical deduction to solve in terms of {theta} of this case was developed employing Genetic Algorithms, where {theta} is a crack propagation direction in plane x-y. Steel and aluminium mechanical properties to modelled specimens were employed, because they are two of materials but used in engineering design. Obtained results show stable zones of fracture propagation but only in a range of applied loading.

    Purpose To further our insight into the role of networks in health system reform, the purpose of this paper is to investigate how one agency, the NSW Agency for Clinical Innovation (ACI), and the multiple networks and enabling resources that it encompasses, govern, manage and extend the potential of networks for healthcare practice improvement. Design/methodology/approach This is a case study investigation which took place over ten months through the first author's participation in network activities and discussions with the agency's staff about their main objectives, challenges and achievements, and with selected services around the state of New South Wales to understand the agency's implementation and large system transformation activities. Findings The paper demonstrates that ACI accommodates multiple networks whose oversight structures, self-organisation and systems change approaches combined in dynamic ways, effectively yield a diversity of network governances. Further, ACI bears out a paradox of "centralised decentralisation", co-locating agents of innovation with networks of implementation and evaluation expertise. This arrangement strengthens and legitimates the role of the strategic hybrid - the healthcare professional in pursuit of change and improvement, and enhances their influence and impact on the wider system. Research limitations/implications While focussing the case study on one agency only, this study is unique as it highlights inter-network connections. Contributing to the literature on network governance, this paper identifies ACI as a "network of networks" through which resources, expectations and stakeholder dynamics are dynamically and flexibly mediated and enhanced. Practical implications The co-location of and dynamic interaction among clinical networks may create synergies among networks, nurture "strategic hybrids", and enhance the impact of network activities on health system reform. Social implications Network governance requires more

    Full Text Available This paper presents a numerical analysis of the relationship between in-plane constraints and the crack tip opening displacement (CTOD for single-edge notched bend (SEN(B specimens under predominantly plane strain conditions. It provides details of the numerical model and discusses the influence of external load and in-plane constraints on the CTOD. The work also reviews methods for determining the CTOD. The new formula proposed in this paper can be used to estimate the value of the coefficient dn as a function of the relative crack length, the strain hardening exponent and the yield strength - dn(n, σ0/E, a/W, with these parameters affecting the level of in-plane constraints. Some of the numerical results were approximated using simple mathematical formulae.

    Full Text Available The AHS (Airborne Hyperspectral Scanner instrument has 80 spectral bands covering the visible and near infrared (VNIR, short wave infrared (SWIR, mid infrared (MIR and thermal infrared (TIR spectral range. The instrument is operated by Instituto Nacional de Técnica Aerospacial (INTA, and it has been involved in several field campaigns since 2004.

    This paper presents an overview of the work performed with the AHS thermal imagery provided in the framework of the SPARC and SEN2FLEX campaigns, carried out respectively in 2004 and 2005 over an agricultural area in Spain. The data collected in both campaigns allowed for the first time the development and testing of algorithms for land surface temperature and emissivity retrieval as well as the estimation of evapotranspiration from AHS data. Errors were found to be around 1.5 K for land surface temperature and 1 mm/day for evapotranspiration.

  20. Is poverty a matter of perspective? Significance of Amartya Sen for the church’s response to poverty: A public practical theological reflection

    Full Text Available Poverty continues to present an enormous challenge to the well-being of humanity. Different frameworks on poverty tend to identify different persons as poor, impacting on efforts to fight poverty. The church as a role player in the public domain needs a framework that can assist it in its task of working for salvation and liberation in the face of overwhelming poverty. Acombined framework, from Amartya Sen’s entitlement approach and capability approach, is amalgamated and suggested as an integrated framework that could act as a lens or a viewpoint from which the church could venture to conceptualise, quantify and respond to instances of poverty. Keywords: Poverty; Church; Well-being; Amartya Sen; Entitlement Approach; Capability Approach

Les mouvements de regard du parleur suivent les modulations quʼil apporte à son attitude coénonciative : lʼabsence de regard correspond à la construction unilatérale par le parleur, dans le préambule, dʼune base commune destinée à faciliter la suite de lʼéchange, alors que le retour de son regard sur lʼécouteur se produit, en cours de rhème, aux moments où il se prépare à exprimer sa position différenciée, en fonction des anticipations quʼil fait des réactions de celui auquel il sʼadresse. Les gestes des mains, pour leur part, anticipant sur lʼexpression morphosyntaxique et lexicale, scandent les étapes de la conceptualisation quʼopère le parleur sur son objet de discours et la manière dont il se saisit dʼune propriété de cet objet. Les mouvements du regard, du geste des mains et de la mélodie interagissent ainsi activement dans la construction du sens à lʼoral en français.

    Tumor patients have an increased risk of nosocomial infection due to hypoimmunity. Infection may affect antitumor therapies and even lead to death. This study aimed to investigate the susceptible factors, the distribution and drug resistance of the pathogens from tumor patients who suffered from nosocomial infection. Clinical records of 952 infected patients in Cancer Center of Sun Yat-sen University during 2006-2007 were reviewed. The infection rate, pathogen spectum and drug resistance of nosocomial infection were analyzed with EXCEL8.0 and SPSS10.0 software. Among the 952 patients, pathogens were detected in 794 patients, with a rate of 83.4%. Of the 794 patients, 321 (40.4%) had gram-negative bacilli (GNB) infection (mainly caused by Escherichia coli), 265 (33.4%) had fungi infection (mainly caused by Candida albicans), and 208 (26.2%) had gram-positive cocci (GPC) infection (mainly caused by staphylococcus and streptococcus species). According to drug sensitivity and resistance test, GNB were sensitive to imipenem and amikacin, but strongly resistant to ampicillin with a rate of >90%; GPC were sensitive to vancomycin, but highly resistant against ampicillin; the fungi were sensitive to amphotericin B, voriconazole and flucytosine, but less sensitive to fluconazol. GNB comprises the majority of pathogens separated from the hospitalized tumor patients in Cancer Center of Sun Yat-sen University from 2006 to 2007. Rational use of antibiotics based on drug sensitivity test could reduce fungi infection and drug resistance, therefore, help to prevent and control nosocomial infection effectively.

    Prediction and control of the dynamics of complex networks is a central problem in network science. Structural and dynamical similarities of different real networks suggest that some universal laws might accurately describe the dynamics of these networks, albeit the nature and common origin of such laws remain elusive. Here we show that the causal network representing the large-scale structure of spacetime in our accelerating universe is a power-law graph with strong clustering, similar to many complex networks such as the Internet, social, or biological networks. We prove that this structural similarity is a consequence of the asymptotic equivalence between the large-scale growth dynamics of complex networks and causal networks. This equivalence suggests that unexpectedly similar laws govern the dynamics of complex networks and spacetime in the universe, with implications to network science and cosmology.

    Glass transition width W of pure Se narrows from 7.1(3) °C to 1.5(2) °C and the non-reversing enthalpy of relaxation (Δ Hnr) at Tg increases from 0.23(5) cal/g to 0.90(5) cal/g upon room temperature aging for 4 months in the dark as examined in modulated differential scanning colorimetry (MDSC) at low scan rates. In Raman scattering, such aging leads the A1 mode of Sen-chains (near 250 cm-1) to narrow by 26% and its scattering strength to decrease as the strength of modes of correlated chains (near 235 cm-1) and of Se8 rings (near 264 cm-1) systematically grows. These calorimetric and Raman scattering results are consistent with the "molecular" chains of Sen, predominant in the fresh glass, reconstructing with each other to compact and partially order the network. Consequences of the aging induced reconstruction of the long super-flexible and uncorrelated Sen-chains are also manifested upon alloying up to 4 mol. % of Ge as revealed by a qualitative narrowing (by 25%) of the Raman vibrational mode of the corner-sharing GeSe4 tetrahedra and a blue-shift of the said mode by nearly 1 cm-1 in 194 cm-1.

    Traditional microscopy-based methods for diagnosis of bacterial vaginosis (BV) are underutilized in many settings, and molecular techniques may provide opportunities for rapid, objective, and accurate BV diagnosis. This study evaluated the quantitative AmpliSens Florocenosis/Bacterial vaginosis-FRT multiplex real-time PCR (Florocenosis-BV) assay. Vaginal samples from a previous study including unselected female subjects (n = 163) and using Amsel criteria and 454 pyrosequencing for BV diagnosis were examined with the Florocenosis-BV test and additionally tested for the presence and quantity of Gardnerella vaginalis clades 3 and 4. The Florocenosis-BV assay demonstrated 100% and 98% sensitivity compared with the Amsel criteria and 454 pyrosequencing, respectively, with 91% specificity. The modified Florocenosis-BV assay (detecting also G. vaginalis clades 3 and 4) resulted in 100% sensitivity vs the Amsel criteria and 454 pyrosequencing with specificity of 86% and 88%, respectively. Further optimizations of thresholds for the quantitative parameters used in the kit resulted in 99-100% accuracy vs Amsel criteria and 454 pyrosequencing for selected parameters. The Florocenosis-BV assay is an objective, accurate, sensitive, and specific method for BV diagnosis; however, the performance of the test can be further improved with some minor optimizations. © 2016 APMIS.

    We present a case of 12-month-old boy with congenitally corrected transposition of great arteries with L-looped ventricles and L-transposition of great arteries and ventricular septal defect. When admitted to the hospital, the patient had the appearance of congestive heart failure due to moderate to severe tricuspid valve regurgitation and right ventricle dysfunction. The pulmonary artery (PA) banding was required first because of low systolic pressure in the morphological left ventricle less than 70% confirmed by catheterization. Three months later, the patient appeared to be a good candidate for anatomical repair and a double switch procedure-Senning with arterial switch-was performed. The early postoperative period was relatively smooth and uneventful. Tricuspid valve insufficiency was resolved immediately after surgery. Mild systolic dysfunction of the left ventricle with mild mitral insufficiency was confirmed by the 2D strain method of echocardiography on the second day of the postoperative period and it improved over the next 21 days. Thirty days later after the procedure, the patient underwent catheterization of his superior vena cava tunnel because of the slightly increased blood flow velocity diagnosed by echocardiography. In 3 months after the surgery, the boy was asymptomatic and was doing well. The patient's functional status was I according to the NYHA classification. © The Author 2016.

    The literature in science education highlights the potentially significant role of outside-school factors such as parents, cultural contexts and role models in students' formation of science attitudes and aspirations, and their attainment in science classes. In this paper, building on and linking Bourdieu's key concepts of habitus, cultural and social capital, and field with Sen's capability approach, we develop a model of students' science-related capability development. Our model proposes that the role of outside-school factors is twofold, first, in providing an initial set of science-related resources (i.e. habitus, cultural and social capital), and then in conversion of these resources to science-related capabilities. The model also highlights the distinction between science-related functionings (outcomes achieved by individuals) and science-related capabilities (ability to achieve desired functionings), and argues that it is necessary to consider science-related capability development in evaluating the effectiveness of science education. We then test our theoretical model with an account of three Turkish immigrant students' science-related capabilities and the role of outside-school factors in forming and extending these capabilities. We use student and parent interviews, student questionnaires and in-class observations to provide an analysis of how outside-school factors influence these students' attitudes, aspirations and attainment in science.

    Full Text Available El objetivo del presente trabajo es analizar el aporte del enfoque de las capacidades de Amartya Sen para el razonamiento ético en salud pública. A partir de las críticas del enfoque de las capacidades al utilitarismo, se propone una concepción de salud sustentada en cuatro características: una noción de vida buena de carácter pluralista, la expansión de la libertad como fundamento ético de las acciones en salud, la concepción de la persona como agente y el reconocimiento de la visión interna de la salud, basada en una objetividad posicional. El aporte del enfoque de las capacidades para el razonamiento ético en salud pública puede resumirse en el reconocimiento de cuatro aspectos: la insuficiencia de la asistencia sanitaria como criterio de la ventaja individual, la equidad en salud como un aspecto fundamental de la justicia social, la relevancia de la visión que tienen las personas con relación a su propia salud y el desarrollo de las capacidades como finalidad de las políticas públicas en el campo de la salud pública.

    In this study, we performed an evaluation of the new CE-marked multiplex real-time AmpliSens N.gonorrhoeae/C.trachomatis/M.genitalium/T.vaginalis-MULTIPRIME-FRT PCR assay compared to APTIMA tests, i.e., APTIMA COMBO 2 assay, APTIMA Trichomonas vaginalis assay (FDA-approved), and two different APTIMA Mycoplasma genitalium assays (research use only; one of them only used for discrepancy analysis). Vaginal swabs (n = 209) and first-void urine (FVU) specimens from females (n = 498) and males (n = 554), consecutive attendees (n = 1261) at a dermatovenerological clinic in Sweden, were examined. The sensitivity of the AmpliSens PCR assay for detection of C. trachomatis (6.3% prevalence), M. genitalium (5.7% prevalence), N. gonorrhoeae (0.3% prevalence), and T. vaginalis (0.08% prevalence) was 97.5% (95% confidence interval (CI): 91.2-99.6%), 81.9% (95% CI: 70.7-89.7%), 100% (95% CI: 40.2-100%) and 100% (95% CI: 16.5-100%), respectively. The specificity of the AmpliSens PCR assay was 100% (95% CI: 99.6-100%) for all agents. The analytical sensitivity and specificity for N. gonorrhoeae detection was excellent, i.e., 55 international gonococcal strains detected and 135 isolates of 13 non-gonococcal Neisseria species were negative. In conclusion, the multiplex real-time AmpliSens N.gonorrhoeae/C.trachomatis/M.genitalium/T.vaginalis-MULTIPRIME-FRT PCR assay demonstrated high sensitivity and excellent specificity for the detection of C. trachomatis, N. gonorrhoeae, and T. vaginalis, and excellent specificity but suboptimal sensitivity for M. genitalium detection. © 2015 APMIS.

    Major depressive disorder (MDD) is characterized by dysfunction in cognitive and emotional systems. However, the neural network correlates of cognitive control (cold cognition) and emotion processing (hot cognition) during the remitted state of MDD (rMDD) remain unclear and not fully probed, which has important implications for identifying intermediate phenotypes of depression risk. 43 young adults with rMDD and 33 healthy controls (HCs) underwent fMRI while completing separate tasks of cold cognition (Parametric Go/No-Go test) and hot cognition (Facial Emotion Processing Test). Two 2 group (rMDD, HC) × 2 event (sad/fearful faces, correct rejections) factorial models of activation were calculated in SPM8. Functional activation was evaluated in the salience and emotional network (SEN) and the cognitive control network (CCN), including hypothesized interaction between group and task within the CCN. Individuals with rMDD demonstrated greater spatial extent of suprathreshold activation within the SEN during sad faces relative to HCs. There were several regions within the CCN in which HCs showed greater activation than rMDD during correct rejections of lures, whereas individuals with rMDD showed greater activation than HCs during sad or fearful faces. Results were not directly compared with active MDD. These results provide evidence of deficient CCN engagement during cognitive control in rMDD (dysfunctional cold cognition). Elevated SEN activation during sad faces could represent heightened salience of negative emotional faces in rMDD; elevated CCN activation during emotional faces in rMDD could represent compensatory regulatory control. These group differences may represent vulnerability factors, scars of prior depressive episodes, or processes maintaining wellness. Copyright © 2017 Elsevier B.V. All rights reserved.

  7. Interconnected networks

    CERN Document Server

    2016-01-01

    This volume provides an introduction to and overview of the emerging field of interconnected networks which include multi layer or multiplex networks, as well as networks of networks. Such networks present structural and dynamical features quite different from those observed in isolated networks. The presence of links between different networks or layers of a network typically alters the way such interconnected networks behave – understanding the role of interconnecting links is therefore a crucial step towards a more accurate description of real-world systems. While examples of such dissimilar properties are becoming more abundant – for example regarding diffusion, robustness and competition – the root of such differences remains to be elucidated. Each chapter in this topical collection is self-contained and can be read on its own, thus making it also suitable as reference for experienced researchers wishing to focus on a particular topic.

As análises ocorreram a partir de secções transversais e longitudinais dos órgãos vegetativos de plantas no estádio de afilhamento. Anatomicamente, o azevém caracteriza-se por apresentar grande quantidade de estômatos e de células buliformes, bem como mesofilo homogêneo constituído apenas de células paliçádicas compactamente distribuídas. Comparativamente, não ocorrem diferenças morfológicas evidentes que possam ser usadas para diferir biótipos sensíveis de resistentes, no entanto, nota-se que biótipos resistentes, especialmente B3R e B4R, apresentaram maior densidade estomática em relação aos demais. Ainda, os biótipos resistentes apresentaram maior quantidade de espaços intercelulares no mesofilo e feixes vasculares com menor quantidade de floema em relação ao xilema, o que, por suas funções na planta, pode colaborar para a menor sensibilidade ao herbicida.This work aimed to contribute to the anatomical knowledge of the species Lolium multiflorum and to observe possible changes that may elucidate the mechanism that confers its resistance to the herbicide glyphosate.

    Full Text Available Since 2009, the radical Muslim movement in northern Nigeria known as Boko Haram has become widely known in Western media for both its militant actions and its ultra-fundamentalist programme. This analysis examines Boko Haram from a historical perspective, viewing the movement as a result of social, political and generational dynamics within the larger field of northern Nigerian radical Islam. The contribution also considers some of the theological dimensions of the dispute between Boko Haram and its Muslim opponents and presents the different stages of militant activity through which this movement has gone so far. The article shows that movements such as Boko Haram are deeply rooted in northern Nigeria’s specific economic, religious and political development and are thus likely to crop up again if basic frame conditions such as social injustice, corruption and economic mismanagement do not change.Seit 2009 wurde die unter dem Namen Boko Haram bekannte radikale muslimische Bewegung in Nordnigeria in westlichen Medien für ihre militanten Aktionen und ihr ultrafundamentalistisches Programm bekannt. Der vorliegende Beitrag untersucht die Bewegung aus historischer Perspektive und sieht die Entstehung von Boko Haram als Ergebnis sozialer, politischer und generationsbezogener Dynamiken innerhalb des radikalen Islam im Norden Nigerias. Der Autor verweist zudem auf theologische Dimensionen der Auseinandersetzung zwischen der Bewegung und ihren muslimischen Gegnern und stellt die verschiedenen Phasen militanter Aktionen Boko Harams dar, die bislang erkennbar sind. Der Beitrag belegt, dass Bewegungen wie Boko Haram tief in den spezifischen ökonomischen, religiösen und politischen Bedingungen im Norden Nigerias verwurzelt sind und daher immer wieder entstehen können, sollten sich wesentliche Rahmenbedingungen – wie soziale Ungerechtigkeit, Korruption und ökonomisches Missmanagement – nicht ändern.

Cet article examinera d’abord pourquoi les savoirs disciplinaires appris à l’école ne sont pas automatiquement réinvestis dans des contextes de nature extrascolaire et pourquoi les savoirs de sens commun résistent à leur déconstruction. La première partie de l’analyse sera marquée par le croisement de discours épistémologiques concernant la nature et la place des savoirs de sens commun dans les conceptions familières de la science. Cet article explorera ensuite les dynamiques qui marquent les relations qu’entretiennent les savoirs disciplinaires scolaires et les savoirs de sens commun en contexte scolaire. Le langage propre à la seconde partie se rattachera davantage aux débats en éducation sur l’importance prépondérante des savoirs de sens commun dans l’apprentissage disciplinaire par concepts. Enfin, nous montrerons qu’il existe des stratégies d’enseignement qui peuvent optimiser l’appropriation intellectuelle des savoirs disciplinaires scolaires et leur transfert dans les interactions quotidiennes.Common sense knowledge is firmly anchored in everyday practices, notably as a result of habit and also for the ontological security it provides. This article will first examine why disciplinary knowledge learned in school is not automatically reinvested in non-school contexts, as well as why common sense knowledge persists in the face of its own deconstruction. The first part of this analysis juxtaposes various epistemological discourses relating to the nature of common sense knowledge and its position in familiar conceptions of science. The article then explores how disciplinary knowledge taught in school and common sense knowledge interact in an educational context. This section of the article will focus mainly on educational debates pertaining to the

    Full Text Available The language of networks now describes everything from the Internet to the economy to terrorist organizations. In distinction to a common view of networks as a universal, originary, or necessary form that promises to explain everything from neural structures to online traffic, this essay emphasizes the contingency of the network imaginary. Network form, in its role as our current cultural dominant, makes scarcely imaginable the possibility of an alternative or an outside uninflected by networks. If so many things and relationships are figured as networks, however, then what is not a network? If a network points towards particular logics and qualities of relation in our historical present, what others might we envision in the future? In  many ways, these questions are unanswerable from within the contemporary moment. Instead of seeking an avant-garde approach (to move beyond networks or opting out of networks (in some cases, to recover elements of pre-networked existence, this essay proposes a third orientation: one of ambivalence that operates as a mode of extreme presence. I propose the concept of "network aesthetics," which can be tracked across artistic media and cultural forms, as a model, style, and pedagogy for approaching interconnection in the twenty-first century. The following essay is excerpted from Network Ambivalence (Forthcoming from University of Chicago Press.

    2017-02-23

    Despite substantial recent progress, our understanding of the principles and mechanisms underlying complex brain function and cognition remains incomplete. Network neuroscience proposes to tackle these enduring challenges. Approaching brain structure and function from an explicitly integrative perspective, network neuroscience pursues new ways to map, record, analyze and model the elements and interactions of neurobiological systems. Two parallel trends drive the approach: the availability of new empirical tools to create comprehensive maps and record dynamic patterns among molecules, neurons, brain areas and social systems; and the theoretical framework and computational tools of modern network science. The convergence of empirical and computational advances opens new frontiers of scientific inquiry, including network dynamics, manipulation and control of brain networks, and integration of network processes across spatiotemporal domains. We review emerging trends in network neuroscience and attempt to chart a path toward a better understanding of the brain as a multiscale networked system.

A metodologia aplicada é descritivo-analítica, além de qualitativa. Para tanto, parte da análise do mercado livre, com seu conceito e implicações, além da visão pautada no desenvolvimento. Sublinha-se a competência do mercado em promover o crescimento. Demonstra que o livre-mercado é a possibilidade de as pessoas realizarem trocas livremente, sem ingerência do Estado. Observa que tais interferências estatais na economia, muitas vezes, prejudicam o desenvolvimento, pois os agentes de mercado têm mais perícia para realizarem os cálculos econômicos. Empós, são estudadas as críticas ao livre-mercado, notadamente a sua incapacidade de combater as mazelas sociais sozinho, especialmente o desemprego, a fome, a pobreza e outros tipos de privação. Aborda a necessidade de coadunar o livre-mercado e o crescimento econômico com desenvolvimento humano, com o fito de proporcionar aos agentes envolvidos no processo de desenvolvimento a participação nos ganhos econômicos, revertendo-os em conquistas sociais. Nessa perspectiva, apresenta a análise de Amartya Sen para essa relação e se enumera os dois polos por meio da concepção de capacidades. Por fim, avalia-se, por intermédio do autor, se o livre-mercado é o melhor meio de crescimento econômico e conclui-se pela incapacidade do mercado, sem a conjunção da atuação estatal, de resolver o desequilíbrio econômico-social. Enfatiza-se a necessidade de uma perspectiva que consiga concatenar livre-mercado e desenvolvimento humano, pelo incremento das capacidades humanas.   Abstract: This article aims to address the issue of relationship between free markets and human development, especially in view of the possibilities of such consistent mechanisms, emphasizing the thought of Amartya Sen

    Full Text Available Wireless Sensor Networks (WSNs monitor environment phenomena and in some cases react in response to the observed phenomena. The distributed nature of WSNs and the interaction between software and hardware components makes it difficult to correctly design and develop WSN systems. One solution to the WSN design challenges is system modeling. In this paper we present a survey of 9 WSN modeling techniques and show how each technique models different parts of the system such as sensor behavior, sensor data and hardware. Furthermore, we consider how each modeling technique represents the network behavior and network topology. We also consider the available supporting tools for each of the modeling techniques. Based on the survey, we classify the modeling techniques and derive examples of the surveyed modeling techniques by using SensIV system.

    Our dependence on networks - be they infrastructure, economic, social or others - leaves us prone to crises caused by the vulnerabilities of these networks. There is a great need to develop new methods to protect infrastructure networks and prevent cascade of failures (especially in cases of coupled networks). Terrorist attacks on transportation networks have traumatized modern societies. With a single blast, it has become possible to paralyze airline traffic, electric power supply, ground transportation or Internet communication. How, and at which cost can one restructure the network such that it will become more robust against malicious attacks? The gradual increase in attacks on the networks society depends on - Internet, mobile phone, transportation, air travel, banking, etc. - emphasize the need to develop new strategies to protect and defend these crucial networks of communication and infrastructure networks. One example is the threat of liquid explosives a few years ago, which completely shut down air travel for days, and has created extreme changes in regulations. Such threats and dangers warrant the need for new tools and strategies to defend critical infrastructure. In this paper we review recent advances in the theoretical understanding of the vulnerabilities of interdependent networks with and without spatial embedding, attack strategies and their affect on such networks of networks as well as recently developed strategies to optimize and repair failures caused by such attacks.

    To investigate the approaches to improve therapeutic effect of stomach cancer by analysis of the long-term results of surgical treatment of this disease. Prognostic factors of stomach cancer were analyzed by Cox multivariate regression model based on clinical data of 2561 stomach cancer cases who underwent surgical treatment from 1964 to 2004 at Sun Yat-sen University Cancer Center. Survival rates were calculated by life table method. Gastrectomy was performed for 1950 cases with resectability of 76.1%, among which there were 1192 cases of curative resection (46.5%) and 758 cases of non-curative resection (29.6%). The other 611 cases of palliative operation included bypass procedures and laparotomy. Operative mortality of all cases was 0.8% and morbidity was 5.1%. For all cases the 1-, 3- and 5-year survival rate was 52.4%, 38.6% and 35.5%, respectively. The stage-specific 5-year survival rate was 86.8% (Stage I), 58.7% (Stage II), 28.4% (Stage III) and 7.6% (Stage IV), respectively. The 5-year survival after curative resection in the period of 40 years was 45.5%, and increased to 52.7% in the last two decades and 61.8% in recent decade. Stage-specific case proportion during the earlier two decades was 1.4% (Stage I), 10.6% (Stage II), 23.1% (Stage III) and 64.9% (Stage IV), respectively, and that during the recent two decades was 9.3%, 18.5%, 35.3% and 36.8%, respectively. The 5-year survival rate of cases during the earlier two decades was 18.0% and increased to 37.5% during the recent two decades. Multivariate analysis indicated that main prognostic factors of stomach cancer included TNM staging, curative resection and multidisciplinary treatment. Early detection and curative resection were the most important measures to improve therapeutic effect of stomach cancer. A surgery-predominant multidisciplinary treatment individualizing biological characteristics of tumor, staging of disease and tumor site will contribute to improvement of therapeutic effect of

    Land cover and crop type maps are one of the most essential inputs when dealing with environmental and agriculture monitoring tasks [1]. During long time neural network (NN) approach was one of the most efficient and popular approach for most applications, including crop classification using remote sensing data, with high an overall accuracy (OA) [2]. In the last years the most popular and efficient method for multi-sensor and multi-temporal land cover classification is convolution neural networks (CNNs). Taking into account presence clouds in optical data, self-organizing Kohonen maps (SOMs) are used to restore missing pixel values in a time series of optical imagery from Landsat-8 satellite. After missing data restoration, optical data from Landsat-8 was merged with Sentinel-1A radar data for better crop types discrimination [3]. An ensemble of CNNs is proposed for multi-temporal satellite images supervised classification. Each CNN in the corresponding ensemble is a 1-d CNN with 4 layers implemented using the Google's library TensorFlow. The efficiency of the proposed approach was tested on a time-series of Landsat-8 and Sentinel-1A images over the JECAM test site (Kyiv region) in Ukraine in 2015. Overall classification accuracy for ensemble of CNNs was 93.5% that outperformed an ensemble of multi-layer perceptrons (MLPs) by +0.8% and allowed us to better discriminate summer crops, in particular maize and soybeans. For 2016 we would like to validate this method using Sentinel-1 and Sentinel-2 data for Ukraine territory within ESA project on country level demonstration Sen2Agri. 1. A.

Trata-se de um estudo qualitativo, realizado em agosto e setembro de 2007, no município de Paula Cândido-MG. Foram entrevistadas 110 mulheres (10% cadastradas no Programa Bolsa Família, selecionadas aleatoriamente. Os dados foram coletados por meio de questionário semiestruturado e analisados por meio da técnica de análise temática. Verificou-se que o desejo por uma "vida melhor" foi, em última instância, o maior sonho das mulheres entrevistadas, sendo o conjunto "educação-trabalho-dinheiro" o meio mais citado para se alcançar uma vida digna. Contudo, a baixa escolaridade, o trabalho precário e informal e a má remuneração constituíram obstáculos à realização de seus sonhos. Diante de tais adversidades, a atitude das entrevistadas variou desde o conformismo e desesperança até o autorreconhecimento de sua situação como sujeito no mundo, capaz de sonhar e acreditar na possibilidade de realização de suas aspirações, utilizando suas habilidades e recursos para lutar por uma "vida melhor". Ressalta-se que uma política de combate à pobreza - como o PBF - deve buscar a expansão das capacidades humanas, articulando-se com ações estruturais, a fim de atingir o objetivo último do referido programa: a emancipação sustentada das famílias beneficiadas e sua inclusão social.The study aimed to analyze the perception of women in situations of social vulnerability, about their dreams and ways of coping with adversities in their daily lives, trying to see how poverty, according to the concepts of Amartya Sen, interfered in their attitude towards life.

    Full Text Available In this paper, we construct a new dynamic model for the Token Bucket (TB algorithm used in computer networks and use systems approach for its analysis. This model is then augmented by adding a dynamic model for a multiplexor at an access node where the TB exercises a policing function. In the model, traffic policing, multiplexing and network utilization are formally defined. Based on the model, we study such issues as (quality of service QoS, traffic sizing and network dimensioning. Also we propose an algorithm using feedback control to improve QoS and network utilization. Applying MPEG video traces as the input traffic to the model, we verify the usefulness and effectiveness of our model.

    In the last decade we have seen the emergence of a new inter-disciplinary field focusing on the understanding of networks which are dynamic, large, open, and have a structure sometimes called random-biased. The field of Complex Networks is helping us better understand many complex phenomena such as the spread of  deseases, protein interactions, social relationships, to name but a few. Studies in Complex Networks are gaining attention due to some major scientific breakthroughs proposed by network scientists helping us understand and model interactions contained in large datasets. In fact, if we could point to one event leading to the widespread use of complex network analysis is the availability of online databases. Theories of Random Graphs from Erdös and Rényi from the late 1950s led us to believe that most networks had random characteristics. The work on large online datasets told us otherwise. Starting with the work of Barabási and Albert as well as Watts and Strogatz in the late 1990s, we now know th...

    1998-03-01

    The engineering problems of constructing autonomous networks of sensors and data processors that can provide alerts for dangerous situations provide a new context for debating the question whether man-made systems can emulate the cognitive capabilities of the mammalian brain. In this paper we consider the question whether a distributed network of sensors and data processors can form ``perceptions`` based on sensory data. Because sensory data can have exponentially many explanations, the use of a central data processor to analyze the outputs from a large ensemble of sensors will in general introduce unacceptable latencies for responding to dangerous situations. A better idea is to use a distributed ``Helmholtz machine`` architecture in which the sensors are connected to a network of simple processors, and the collective state of the network as a whole provides an explanation for the sensory data. In general communication within such a network will require time division multiplexing, which opens the door to the possibility that with certain refinements to the Helmholtz machine architecture it may be possible to build sensor networks that exhibit a form of artificial consciousness.

    HIV-1 viral load (VL) testing is not widely available in resource-limited settings. The use of finger prick dried blood spot (FP-DBS) samples could remove barriers related to sample collection and transport. Measurement of VL using DBS from EDTA venous blood (VB-DBS) in place of plasma has previously been validated using the NucliSENS Easy-Q HIV-1 v2.0 assay, but information on the accuracy of FP-DBS samples for measuring VL is limited. This prospective study, conducted at Thyolo District Hospital in southern Malawi, compared VL levels measured on FP-DBS samples and plasma using the NucliSENS Easy-Q HIV-1 v2.0 assay. Comparability was assessed by means of agreement and correlation (131 patients with VLs of ≥100 copies/ml), sensitivity, and specificity (612 patients on antiretroviral treatment [ART]). Samples of EDTA venous blood and FP-DBS from 1,009 HIV-infected individuals were collected and prepared in the laboratory. Bland-Altman analysis found good agreement between plasma and FP-DBS VL levels, with a mean difference of -0.35 log10, and 95% limits of agreement from -1.26 to 0.55 log10. FP-DBS had a sensitivity of 88.7% (95% confidence interval [CI], 81.1 to 94.4%) and a specificity of 97.8% (95% CI, 96.1 to 98.9%) using a 1,000-copies/ml cut point and a sensitivity of 83.0% (95% CI, 73.4 to 90.1%) and a specificity of 100% (95% CI, 99.3 to 100%) using a 5,000-copies/ml cut point. This study shows that FP-DBS is an acceptable alternative to plasma for measuring VL using the NucliSENS Easy-Q HIV-1 v2.0. We are conducting a second study to assess the proficiency of health workers at preparing FP-DBS in primary health care clinics.

    On Sunday 12 June 2005, a site-wide security software upgrade will be performed on all CERN network equipment. This maintenance operation will cause at least 2 short network interruptions of 2 minutes on each equipment item. There are hundreds of such items across the CERN site (Meyrin, Prévessin and all SPS and LHC pits), and it will thus take the whole day to treat them all. All network users and services will be affected. Central batch computing services will be interrupted during this period, expected to last from 8 a.m. until late evening. Job submission will still be possible but no jobs will actually be run. It is hoped to complete the computer centre upgrades in the morning so that stable access can be restored to lxplus, afs and nice services as soon as possible; this cannot be guaranteed, however. The opportunity will be used to interrupt and perform upgrades on the CERN Document Servers.

    Nuclear lamins are intermediate filament proteins that represent important structural components of metazoan nuclear envelopes (NEs). By combining proteomics and superresolution microscopy, we recently reported that both A- and B-type nuclear lamins form spatially distinct filament networks at the nuclear periphery of mouse fibroblasts. In particular, A-type lamins exhibit differential association with nuclear pore complexes (NPCs). Our studies reveal that the nuclear lamina network in mammalian somatic cells is less ordered and more complex than that of amphibian oocytes, the only other system in which the lamina has been visualized at high resolution. In addition, the NPC component Tpr likely links NPCs to the A-type lamin network, an association that appears to be regulated by C-terminal modification of various A-type lamin isoforms. Many questions remain, however, concerning the structure and assembly of lamin filaments, as well as with their mode of association with other nuclear components such as peripheral chromatin.

    This study aims to evaluate the clinical performance of the NucliSENS EasyQ assay and compare it with HPV DNA genotyping for the detection of high-grade squamous intraepithelial lesions (HSIL) and cancer in a Korean population. In 188 total thin prep samples, the remaining fluid after cytology slide preparation was tested with Goodgene HPV DNA chips and the NucliSENS EasyQ HPV E6/E7 messenger RNA (mRNA) assay. The sensitivity and specificity of each test were calculated with HSIL and squamous cell carcinoma (SCC) as the disease endpoint. Out of the 188 samples, 139 (74%) were positive for DNA of 14 HPV types, while 57 (30%) cases were positive for E6/E7 mRNA. The DNA test was positive in cytology cases of SCC, HSIL, and atypical squamous cell. The mRNA test yielded results of 75%, 74%, 60%, 56%, and 29% positivity in abnormal cytology cases of SCC, HSIL, atypical squamous cells - cannot exclude HSIL, atypical squamous cells of undetermined significance, and low-grade squamous intraepithelial lesion, respectively. In normal cytology cases, the positivity rates were 9% and 53% for the mRNA and DNA tests, respectively. For detection of HSIL and SCC, the sensitivity of the mRNA test was 74.36% and that of the DNA test was 100%, while the specificities of the tests were 85% and 40.83%, respectively. These findings suggest that the HPV E6/E7 mRNA assay can overcome the shortcoming of low specificity of DNA assays for clinical detection of high-grade cervical lesions and malignancies.

    We introduce the construction of a new framework for probing discrete emergent geometry and boundary-boundary observables based on a fundamentally a-dimensional underlying network structure. Using a gravitationally motivated action with Forman weighted combinatorial curvatures and simplicial volumes relying on a decomposition of an abstract simplicial complex into realized embeddings of proper skeletons, we demonstrate properties such as a minimal volume-scale cutoff, the necessity of a term playing the role of a positive definite cosmological constant as a regulator for nondegenerate geometries, and naturally emergent simplicial structures from Metropolis network evolution simulations with no restrictions on attachment rules or regular building blocks. We see emergent properties which echo results from both the spinfoam formalism and causal dynamical triangulations in quantum gravity, and provide analytical and numerical results to support the analogy. We conclude with a summary of open questions and intent for future work in developing the program.

    Citation between papers can be treated as a causal relationship. In addition, some citation networks have a number of similarities to the causal networks in network cosmology, e.g., the similar in-and out-degree distributions. Hence, it is possible to model the citation network using network cosmology. The casual network models built on homogenous spacetimes have some restrictions when describing some phenomena in citation networks, e.g., the hot papers receive more citations than other simultaneously published papers. We propose an inhomogenous causal network model to model the citation network, the connection mechanism of which well expresses some features of citation. The node growth trend and degree distributions of the generated networks also fit those of some citation networks well.

    Hu, Yimei

    Open innovation in networks has been a popular topic for long, this paper rethinks the concepts of innovation network and network organization, and clarifies the differences between them based on the network perspective. Network perspective means that: network is the context of firms; market...... and hierarchy can be analyzed from a network approach. Within a network perspective, there are different levels of network, and a firm may not always has the power to “manage” innovation networks due to different levels of power. Based on the strength of a firm’s power, its role may varies from manager...

    Full Text Available O ozônio troposférico causa necroses foliares em Nicotiana tabacum. Cultivares de tabaco são muito utilizadas como bioindicadoras de ozônio, em programas de biomonitoramento da qualidade do ar. Dentre elas destacam-se as cultivares Bel-W3 (sensível e Bel-B (tolerante. Este estudo teve como objetivo verificar se as duas cultivares apresentam variações na estrutura foliar que possam ajudar a explicar a diferença na sensibilidade ao ozônio que ambas apresentam. Em plantas que cresceram em ambiente isento de poluentes aéreos foram coletadas folhas do terceiro nó e que foram processadas segundo técnicas usuais empregadas em anatomia vegetal. Realizaram-se análises quantitativas e qualitativas dos tecidos foliares. A cultivar Bel-W3, quando comparada à Bel-B, apresentou menor densidade estomática na superfície abaxial e maior espessura do mesofilo. Qualitativamente as células de ambas cultivares mostraram aspecto sadio, com os vacúolos ocupando praticamente todo o volume celular. A cultivar sensível apresentou visivelmente mais espaços intercelulares, câmaras estomáticas maiores e estômatos ligeiramente salientes em ambas superfícies foliares. Tais características, que facilitam a entrada e a difusão dos poluentes na folha, podem explicar, do ponto de vista estrutural, a maior sensibilidade da cultivar Bel-W3.Tropospheric ozone produces symptoms such as leaf injury in Nicotiana tabacum. Tobacco cultivars are often used as ozone indicators in air-quality biomonitoring programs. Bel-W3 (sensitive and Bel-B (tolerant cultivars are better known. The aim of this study was to verify if the two cultivars show variation in leaf structure that may help to explain differences in ozone sensitivity. Expanded leaves from plants growing in pollutant-free air were collected, processed according to the usual techniques of plant anatomy, and analyzed quantitatively and qualitatively. The sensitive cultivar showed lower stomatal density on the

    State-of-the-art techniques borrowed from particle accelerators and detectors are a key element in hadrontherapy and several European projects are actively fostering the collaboration amongst the various disciplines and countries. ENLIGHT was established in 2002 to coordinate these European efforts in hadron therapy. The ENLIGHT network is formed by the European hadrontherapy Community, with more than 300 participants from twenty European countries. A major achievement of ENLIGHT has been the blending of traditionally separate communities so that clinicians, physicists, biologists and engineers with experience and interest in particle therapy are working together.

    Full Text Available Cet article propose d’identifier les enjeux politiques de l’expression dans l’espace public en Syrie et plus spécifiquement ceux relatifs à l’expression artistique, au prisme du dernier festival de cinéma de Damas, événement catalyseur mais aussi réceptacle des différentes formes de la politisation de la culture. Cet angle d’approche nous permet de mettre en lumière les tentatives d’un régime autoritaire pour contrôler la production du sens et imposer ses interprétations des événements. Ce contexte n’a cependant nullement empêché l’existence de pratiques expressives polymorphes, voire contestataires, rendues possibles par diverses stratégies de contournement, de mises à distance, dont nous donnons des exemples dans des registres différents : les dernières mobilisations patriotiques anti-Mehlis et l’expression cinématographique qui a eu un rôle précurseur dans la publicisation de remises en question de la référence politique dominante.

    Full Text Available Este artículo utiliza una narración literaria para mostrar de qué manera la teoría ortodoxa o tradicional, especialmente el pensamiento de la escuela neoclásica, deja de lado el concepto de pobreza, al considerar el bienestar como la simple obtención de utilidades; además se presenta la propuesta del economista Amartya Sen, que postula la teoría de las capacidades humanas. Esta teoría establece como importante todo aquello que una persona es capaz de hacer o ser para conseguir sus objetivos y sus fines, permitiendo así, incluir y ampliar la visión de la pobreza. Al final se concluye que, a pesar de que la pobreza debe ser estudiada por la Economía, ésta se ha visto avocada a una imposibilidad de plantear soluciones para que aquella disminuya y, en gran medida, ello se debe a los limitantes que presenta la teoría ortodoxa.

  18. Animal transportation networks

    Perna, Andrea; Latty, Tanya

    2014-01-01

    Many group-living animals construct transportation networks of trails, galleries and burrows by modifying the environment to facilitate faster, safer or more efficient movement. Animal transportation networks can have direct influences on the fitness of individuals, whereas the shape and structure of transportation networks can influence community dynamics by facilitating contacts between different individuals and species. In this review, we discuss three key areas in the study of animal transportation networks: the topological properties of networks, network morphogenesis and growth, and the behaviour of network users. We present a brief primer on elements of network theory, and then discuss the different ways in which animal groups deal with the fundamental trade-off between the competing network properties of travel efficiency, robustness and infrastructure cost. We consider how the behaviour of network users can impact network efficiency, and call for studies that integrate both network topology and user behaviour. We finish with a prospectus for future research. PMID:25165598

    2010-01-01

    A noisy network coding scheme for sending multiple sources over a general noisy network is presented. For multi-source multicast networks, the scheme naturally extends both network coding over noiseless networks by Ahlswede, Cai, Li, and Yeung, and compress-forward coding for the relay channel by Cover and El Gamal to general discrete memoryless and Gaussian networks. The scheme also recovers as special cases the results on coding for wireless relay networks and deterministic networks by Avestimehr, Diggavi, and Tse, and coding for wireless erasure networks by Dana, Gowaikar, Palanki, Hassibi, and Effros. The scheme involves message repetition coding, relay signal compression, and simultaneous decoding. Unlike previous compress--forward schemes, where independent messages are sent over multiple blocks, the same message is sent multiple times using independent codebooks as in the network coding scheme for cyclic networks. Furthermore, the relays do not use Wyner--Ziv binning as in previous compress-forward sch...

    2017-06-01

    Despite evidence that large professional networks afford a host of financial and professional benefits, people vary in how motivated they are to build such networks. To help explain this variance, the present article moves beyond a rational self-interest account to examine the possibility that identity shapes individuals' intentions to network. Study 1 established a positive association between viewing professional networking as identity-congruent and the tendency to prioritize strengthening and expanding one's professional network. Study 2 revealed that manipulating the salience of the self affects networking intentions, but only among those high in networking identity-congruence. Study 3 further established causality by experimentally manipulating identity-congruence to increase networking intentions. Study 4 examined whether identity or self-interest is a better predictor of networking intentions, providing support for the former. These findings indicate that identity influences the networks people develop. Implications for research on the self, identity-based motivation, and professional networking are discussed.

    respond appropriately to children and youngsters with Special Educational Needs (SEN, so as to optimize their participation in activities. Today it has become a challenge to determine exactly which students have special needs and, therefore, who should benefit from Special Education intervention, especially those with permanent need of attention. In this context, the International Classification of Functioning, Disability and Health (ICF, as recommended by WHO (2001 and updated in 2003, is a pedagogical tool in the process of eligibility, assessment and intervention for students with SEN. There is a paradigm shift, which intends not only to classify the level of functionality of the individual, but also the environmental factors that can act as barriers or facilitators of this functionality. In this perspective, teacher education is considered an important factor for success. Thus the continuous training must advocate and enable a change in the teachers’ education practices, that is, a change in the educational practice and intervention.

    SEN is a newly discovered blood-transmissible virus. Among its variants, SENV-D and -H are most often associated with non-A, -E hepatitis. Very little is known about the risk of vertical transmission of the virus. By using polymerase chain reaction with specific primers for SENV-D and -H, we investigated the prevalence of SENV-H and -D infection, the transmission rate of SENV infection and clinical features of SENV-infected children in 89 hepatitis C virus (HCV)-positive human immunodeficiency virus type 1-negative mothers. SENV infection was found in 36 (40%) mothers, and SENV-D was more frequent than SENV-H infection (34/36, 94%vs 5/36, 14%, P < 0.01). No difference in SENV infection rates was found between injection drug user (IDU) mothers (17/51, 33%) and mothers with no risk for bloodborne infection (19/38, 50%, P = ns). SENV-H infection was found only in IDU mothers and mothers with HCV genotype1b. Both SENV-D and -H can be transmitted to the offspring with an overall rate of 47%. Vertical transmission of HCV does not facilitate SENV infection of the offspring. Among 17 SENV-infected children, none was co-infected with HCV. Maternal HCV genotype or viral load does not interfere with mother-to-infant transmission of SENV. Persistence of SENV infection was demonstrated in 100% of infected children after 1-year follow-up, but none had clinical evidence of liver disease.

As chances de internação por pneumonia foram 2,7 (IC: 1,3-5,4 vezes maiores em crianças de 0,1 a 5,9 meses; 1,9 (IC: 1,1-3,3 vezes maiores nas crianças que tiveram a duração da hospitalização variando de 8 a 14 dias; e 3,0 (IC: 1,2-7,5 vezes maiores nas crianças com diagnóstico secundário de desnutrição. O excesso de internações evitáveis é um forte indício da baixa qualidade das ações em terras indígenas e do limitado acesso à atenção primária, contrariando o modelo assistencial proposto pelo subsistema de saúde indígena no Brasil que, em tese, deveria privilegiar tecnologias assistenciais ancoradas na atenção primária.

    The self-expandable COMPLETE™ stent (Medtronic) has greater elasticity, allowing it to regain its shape after the compression force reduces, and has higher trackability, thus is easier to maneuver through tortuous vessels, whereas the balloon-expandable SCUBA™ stent (Medtronic) has higher radial stiffness and can afford more accurate placement without geographic miss, which is important in aortoiliac bifurcation lesions. To date, there have been no randomized control trials comparing efficacy and safety between the self-expanding stent and balloon-expandable stent in advanced atherosclerotic iliac artery disease. The purpose of our study is to examine primary patency (efficacy) and incidence of stent fracture and geographic miss (safety) between two different major representative stents, the self-expanding nitinol stent (COMPLETE-SE™) and the balloon-expanding cobalt-chromium stent (SCUBA™), in stenotic or occlusive iliac arterial lesions. This trial is designed as a prospective, randomized, multicenter trial to demonstrate a noninferiority of SCUBA™ stent to COMPLETE-SE™ stent following balloon angioplasty in iliac arterial lesions, and a total of 280 patients will be enrolled. The primary end point of this study is the rate of primary patency in the treated segment at 12 months after intervention as determined by catheter angiography, computed tomography angiography, or duplex ultrasound. The SENS-ILIAC trial will give powerful insight into whether the stent choice according to deployment mechanics would impact stent patency, geographic miss, or stent fracture in patients undergoing stent implantation in iliac artery lesions.

    Full Text Available Cette étude porte sur la question du sens des concepts de développement durable et d’agriculture durable à travers, d’une part, une analyse de contenu de leur diffusion dans la presse régionale (presse spécialisée en milieu agricole et presse généraliste. D’autre part, elle s’intéresse à l’appropriation de ces concepts par les agriculteurs. Pour ce faire, des entretiens semi-directifs ont été menés auprès de ces acteurs en prise avec ces questions de « durabilité ». L’objectif est de mettre en parallèle ces deux formes de contenu et de mettre en lumière les représentations sociales liées à ces objets en partant du postulat que ces dernières, en tant que forme de connaissance socialement élaborées, sont un guide pour l’action et que celles-ci se forment, se transmettent, et évoluent au cœur de la communication (Moscovici, 1976.This study focuses on the meaning of the concepts of sustainable development and sustainable agriculture. First, this study deals with a content analysis of their circulation in the regional papers (specialized in agriculture and popular newspaper. Second, it is interested in the appropriation of theses concepts farmers. Semi-structured interviews were carried out with these stakeholders concerned with these issues. The aim of the study is to compare these two content analyses and to highlight the social representations of these concepts. We postulate that these representations are a form of knowledge which is socially constructed. They are a guide to action and that they take shape, they are transmitted and they evolve in the heart of communication (Moscovici, 1976.

    Full Text Available Human immunodeficiency virus type 1 (HIV-1 genetic diversity poses a challenge to reliable viral load monitoring. Discrepancies between different testing platforms have been observed, especially for non-clade-B virus. Therefore we compare, in antiretroviral therapy (ART-naïve South African subjects predominantly infected with HIV-1 clade-C, three commercially available assays: the COBAS AmpliPrep/COBAS TaqMan HIV-1 Test version 2.0 by Roche (CAP/CTM v2.0, the BioMérieux NucliSens Version 2.0 Easy Q/Easy Mag (NucliSens v2.0 and the Roche COBAS Amplicor HIV-1 Monitor Test Version 1.5 (Amplicor v1.5. Strong linear correlation was observed and Bland-Altman analyses showed overall good agreement between the assays with mean viral load differences of 0.078 log cp/ml (NucliSens v2.0 - Amplicor v1.5, 0.260 log cp/ml (CAP/CTM v2.0 - Amplicor v1.5 and 0.164 log cp/ml (CAP/CTM v2.0 - NucliSens v2.0, indicating lower mean viral load results for the Amplicor v1.5 and higher mean readings for the CAP/CTM v2.0. Consistent with observations following previous comparisons of CAP/CTM v2.0 versus Amplicor v1.5, the CAP/CTM v2.0 assay detected low-level viremia (median 65 cp/ml in more than one-third of those in whom viremia had been undetectable (<20 cp/ml in assays using the NucliSens platform. These levels of viremia are of uncertain clinical significance but may be of importance in early detection of ART resistance in those on treatment. Overall the three assays showed good comparability of results but with consistent, albeit relatively small, discrepancies for HIV-1 clade-C samples, especially in the low-viremic range that should be taken into account when interpreting viral load data.

    Full Text Available Cette contribution propose de s’intéresser à la dimension interprétative de l’« analyse des politiques publiques ». Cette dimension a été mise en avant par un courant de recherches qui semble avoir bénéficié d’un écho moins important dans la sphère francophone que dans la sphère anglo-saxonne. Sous différentes formes, ce courant est défendu par des auteurs influents comme Frank Fischer, Dvora Yanow, Mark Bevir, r.a.w. rhodes. Il se distingue des travaux français qui prétendent intégrer la question du sens par une approche le plus souvent qualifiée de « cognitive ». Par la mise en perspective de ce courant de recherches qui prétend prolonger un « tournant interprétatif », l’objectif de cette contribution est notamment de ressaisir ce que peut être un travail analytique sur les politiques publiques, précisément en soulignant les lacunes que peut engendrer l’absence d’une appréhension interprétative. De fait, beaucoup de travaux récents touchant ce qu’il est convenu d’appeler l’« analyse des politiques publiques » ou la « sociologie de l’action publique » font preuve d’un grand raffinement sociologique dans leurs analyses. Le lecteur peut souvent y voir des jeux d’acteurs minutieusement étudiés, mais il peut ressentir un manque dans la mesure où il n’a tout aussi souvent guère de clés pour saisir le sens de ces activités. La question peut donc se poser de la recherche d’un positionnement différent dans la manière d’élaborer l’analyse à partir des informations recueillies. Dégager des raisons ou des causes ne relève pas du même ordre de pensée que saisir un sens. Une démarche interprétative peut réduire les risques de confinement dans la sophistication d’une micro-analyse ; en évitant de faire des processus étudiés des épisodes particuliers et presque indépendants de leur contexte d’origine, elle peut ouvrir vers des possibilités d

    Populations are seldom completely isolated from their environment. Individuals in a particular geographic or social region may be considered a distinct network due to strong local ties but will also interact with individuals in other networks. We study the susceptible-infected-recovered process on interconnected network systems and find two distinct regimes. In strongly coupled network systems, epidemics occur simultaneously across the entire system at a critical infection strength βc, below which the disease does not spread. In contrast, in weakly coupled network systems, a mixed phase exists below βc of the coupled network system, where an epidemic occurs in one network but does not spread to the coupled network. We derive an expression for the network and disease parameters that allow this mixed phase and verify it numerically. Public health implications of communities comprising these two classes of network systems are also mentioned.

    A method and apparatus for protecting virtual machines. A computer system creates a copy of a group of the virtual machines in an operating network in a deception network to form a group of cloned virtual machines in the deception network when the group of the virtual machines is accessed by an adversary. The computer system creates an emulation of components from the operating network in the deception network. The components are accessible by the group of the cloned virtual machines as if the group of the cloned virtual machines was in the operating network. The computer system moves network connections for the group of the virtual machines in the operating network used by the adversary from the group of the virtual machines in the operating network to the group of the cloned virtual machines, enabling protecting the group of the virtual machines from actions performed by the adversary.

  2. Morphological neural networks

    Energy Technology Data Exchange (ETDEWEB)

    Ritter, G.X.; Sussner, P. [Univ. of Florida, Gainesville, FL (United States)

    1996-12-31

    The theory of artificial neural networks has been successfully applied to a wide variety of pattern recognition problems. In this theory, the first step in computing the next state of a neuron or in performing the next layer neural network computation involves the linear operation of multiplying neural values by their synaptic strengths and adding the results. Thresholding usually follows the linear operation in order to provide for nonlinearity of the network. In this paper we introduce a novel class of neural networks, called morphological neural networks, in which the operations of multiplication and addition are replaced by addition and maximum (or minimum), respectively. By taking the maximum (or minimum) of sums instead of the sum of products, morphological network computation is nonlinear before thresholding. As a consequence, the properties of morphological neural networks are drastically different than those of traditional neural network models. In this paper we consider some of these differences and provide some particular examples of morphological neural network.

RESULTS: NG presented significant losses of tactile and thermal sensitivity in comparison with CG, especially in the heels (49.0% of NG and 97.3% of CG. Muscle function was decreased in NG, with predominance of loss of grade 5. The muscles most affected were the interossei (23.4%, extensor hallucis (42.5% and triceps surae (43.2%, while all muscle function was preserved in CG. All ranges of motion in NG were reduced in comparison with CG. The functional tests on the ankles in NG presented a decrease of around 50%. CONCLUSION: There were significant differences between the groups with regard to sensitivity, muscle function, range of motion and functional losses. These differences can be attributed to the diabetic neuropathy.

    Full Text Available Cet article a pour objet l’analyse de la déconnexion entre forme et sens dans les énoncés où figurent les verbes de perception à emploi dit copule (look, sound, smell, taste et feel. L’origine de ces verbes est sujette à débat et il est avancé ici une hypothèse sur l’origine nominale de ces verbes, ainsi que sur leur comportement syntaxique et sémantique unique. Il apparaît que, dans ce type d’énoncés, le sujet grammatical n’est pas le sujet logique du verbe, qui a un emploi modalisant en ce qu’il exprime un jugement sur les apparences perceptuelles. Ce conflit apparent entre syntaxe et sémantique transparaît également au niveau de certains types d’attributs du sujet (les syntagmes nominaux, les syntagmes prépositionnels introduits par OF et les propositions en AS IF / AS THOUGH. L’étude montre que tous les attributs renvoient nécessairement à des propriétés gradables, ce qui n’est pas le cas avec le verbe copule be. Ainsi, ces énoncés copulatifs, où le verbe de perception a un emploi modalisant, présentent tous, à plusieurs titres et de diverses manières, un phénomène de compression syntaxique et sémantique motive par l’application d’un principe d’économie langagière.This paper aims at analysing the disconnection between form and meaning in sentences involving copular perception verbs (look, sound, smell, taste and feel. The origin of these verbs is a controversial issue, and in this article, it is argued that they have a nominal origin and that they have identical syntactic and semantic features. It appears that, in these copulative sentences, the grammatical subject does not coincide with the underlying subject of the verb, which has a modalising use as it expresses a judgment concerning sensory appearances. This surface conflict between syntax and semantics also shows in certain types of subject complements – nominal phrases, OF-prepositional phrases and AS IF/AS THOUGH-clauses. This

It is widely recognized that contact networks are indispensable for describing, understanding, and intervening to stop the spread of infectious diseases in human and animal populations; “network epidemiology” is an umbrella term to describe this research field. More recently, contact networks have been recognized as being highly dynamic. This observation, also supported by an increasing amount of new data, has led to research on temporal networks, a rapidly growing area. Changes in network structure are often informed by epidemic (or other) dynamics, in which case they are referred to as adaptive networks. This volume gathers contributions by prominent authors working in temporal and adaptive network epidemiology, a field essential to understanding infectious diseases in real society.

    The focus of this project was on the development of a "Network Service Plane" as an abstraction model for the control and provisioning of multi-layer networks. The primary motivation for this work were the requirements of next generation networked applications which will need to access advanced networking as a first class resource at the same level as compute and storage resources. A new class of "Intelligent Network Services" were defined in order to facilitate the integration of advanced network services into application specific workflows. This new class of network services are intended to enable real-time interaction between the application co-scheduling algorithms and the network for the purposes of workflow planning, real-time resource availability identification, scheduling, and provisioning actions.

    Dynamical networks are systems of active elements (nodes) interacting with each other through links. Examples are power grids, neural structures, coupled chemical oscillators, and communications networks, all of which are characterized by a networked structure and intrinsic dynamics of their interacting components. If the coupling structure of a dynamical network can change over time due to nodal dynamics, then such a system is called an adaptive dynamical network. The term ‘adaptive’ implies that the coupling topology can be rewired; the term ‘dynamical’ implies the presence of internal node and link dynamics. The main results of research on adaptive dynamical networks are reviewed. Key notions and definitions of the theory of complex networks are given, and major collective effects that emerge in adaptive dynamical networks are described.

    Class network routing is implemented in a network such as a computer network comprising a plurality of parallel compute processors at nodes thereof. Class network routing allows a compute processor to broadcast a message to a range (one or more) of other compute processors in the computer network, such as processors in a column or a row. Normally this type of operation requires a separate message to be sent to each processor. With class network routing pursuant to the invention, a single message is sufficient, which generally reduces the total number of messages in the network as well as the latency to do a broadcast. Class network routing is also applied to dense matrix inversion algorithms on distributed memory parallel supercomputers with hardware class function (multicast) capability. This is achieved by exploiting the fact that the communication patterns of dense matrix inversion can be served by hardware class functions, which results in faster execution times.

    Full Text Available O futebol, devido ao seu alto nível de esforço e exigibilidade por parte dos atletas, está associado a diferentes tipos de lesões. A falta da aplicação de programas de prevenção pode contribuir para que essa ocorrência seja cada vez maior. O presente estudo avaliou a resposta sensório-motora e funcionalidade dos atletas de uma escolinha de futebol de Brasília/DF, após terem sido submetidos ao programa de prevenção de lesões FIFA “The 11+”. Foram estudados 12 atletas do gênero masculino, com a média de idade de 14 anos, estatura 1,65cm e peso de 52 kg. Apenas um era canhoto e nenhum apresentava histórico de lesão em membros inferiores. A avaliação da resposta sensório-motora foi feita por meio da eletromiografia (EMG nos músculos vasto medial, lateral e reto femoral durante a execução do Star Excursion Balance Test – SEBT, e a funcionalidade por meio do Single Leg Hop Test - SLHT. Em ambos os procedimentos, foram analisados os membros dominante e não dominante. Os resultados encontrados demonstraram diferenças estatisticamente significativas entre as intervenções na EMG dos músculos vasto lateral e reto femoral e no SLHT do membro inferior direito. Conclui-se que a participação no programa FIFA “The 11+” promoveu aumento tanto da resposta sensório – motora, quanto da funcionalidade do grupo de atletas estudados.

  15. Membrane fluidity and lipid composition of fluconazole resistant and susceptible strains of Candida albicans isolated from diabetic patients Fluidez e composição lipídica da membrana de cepas de Candida albicans resistentes e sensíveis ao fluconazol, isoladas de pacientes diabéticos

    Full Text Available Ten clinical isolates of Candida albicans, five strains belonging to each of fluconazole resistant and susceptible groups isolated from diabetic patients, were studied for the membrane fluidity and lipid composition. Compared to fluconazole susceptible strains, fluconazole resistant ones exhibited enhanced membrane fluidity as measured by fluorescence polarization technique. The increased membrane fluidity was reflected in the decreased p-values exhibited by the resistant strains. On the other hand, susceptible isolates contained higher amount of ergosterol, almost twice as compared to resistant isolates which might have contributed to their lower membrane fluidity. However, no significant alteration was observed in the phospholipid and fatty acid composition of these isolates. Labeling experiments with fluorescamine dye revealed that the percentage of the exposed aminophospholipid, phosphatidylethanolamine was highest in the resistant strains as compared to the susceptible strains, indicating a possible overexpression of CDR1 and CDR2 genes in resistant strains. The results presented here suggest that the changes in the ergosterol content and overexpression of ABC transporter genes CDR1 and CDR2 could contributeto fluconazole resistance in C. albicans isolated from diabetic patients.Dez isolados clínicos, sendo cinco resistentes e cinco sensíveis ao fluconazol, obtidos de pacientes diabéticos, foram estudados quanto à fluidez e composição química da membrana. Quando comparados aos isolados sensíveis ao fluconazol, os isolados resistentes apresentaram fluidez de membrana aumentada, conforme mensurado pela técnica de polarização fluorescente. A fluidez de membrana aumentada refletiu-se pelos valores mais baixos de p. Por outro lado, os isolados sensíveis continham quantidades mais elevadas de ergosterol, quase o dobro dos isolados resistentes, o que pode ter contribuído para a fluidez de membrana mais baixa.

    2014-11-06

    Many group-living animals construct transportation networks of trails, galleries and burrows by modifying the environment to facilitate faster, safer or more efficient movement. Animal transportation networks can have direct influences on the fitness of individuals, whereas the shape and structure of transportation networks can influence community dynamics by facilitating contacts between different individuals and species. In this review, we discuss three key areas in the study of animal transportation networks: the topological properties of networks, network morphogenesis and growth, and the behaviour of network users. We present a brief primer on elements of network theory, and then discuss the different ways in which animal groups deal with the fundamental trade-off between the competing network properties of travel efficiency, robustness and infrastructure cost. We consider how the behaviour of network users can impact network efficiency, and call for studies that integrate both network topology and user behaviour. We finish with a prospectus for future research. © 2014 The Author(s) Published by the Royal Society. All rights reserved.

  13. Is the immune network a complex network?

    CERN Document Server

    Souza-e-Silva, Hallan

    2012-01-01

    Some years ago a cellular automata model was proposed to describe the evolution of the immune repertoire of B cells and antibodies based on Jerne's immune network theory and shape-space formalism. Here we investigate if the networks generated by this model in the different regimes can be classified as complex networks. We have found that in the chaotic regime the network has random characteristics with large, constant values of clustering coefficients, while in the ordered phase, the degree distribution of the network is exponential and the clustering coefficient exhibits power law behavior. In the transition region we observed a mixed behavior (random-like and exponential) of the degree distribution as opposed to the scale-free behavior reported for other biological networks. Randomness and low connectivity in the active sites allow for rapid changes in the connectivity distribution of the immune network in order to include and/or discard information and generate a dynamic memory. However it is the availabil...

  16. Dominating biological networks.

    Directory of Open Access Journals (Sweden)

    Tijana Milenković

    Full Text Available Proteins are essential macromolecules of life that carry out most cellular processes. Since proteins aggregate to perform function, and since protein-protein interaction (PPI networks model these aggregations, one would expect to uncover new biology from PPI network topology. Hence, using PPI networks to predict protein function and role of protein pathways in disease has received attention. A debate remains open about whether network properties of "biologically central (BC" genes (i.e., their protein products, such as those involved in aging, cancer, infectious diseases, or signaling and drug-targeted pathways, exhibit some topological centrality compared to the rest of the proteins in the human PPI network.To help resolve this debate, we design new network-based approaches and apply them to get new insight into biological function and disease. We hypothesize that BC genes have a topologically central (TC role in the human PPI network. We propose two different concepts of topological centrality. We design a new centrality measure to capture complex wirings of proteins in the network that identifies as TC those proteins that reside in dense extended network neighborhoods. Also, we use the notion of domination and find dominating sets (DSs in the PPI network, i.e., sets of proteins such that every protein is either in the DS or is a neighbor of the DS. Clearly, a DS has a TC role, as it enables efficient communication between different network parts. We find statistically significant enrichment in BC genes of TC nodes and outperform the existing methods indicating that genes involved in key biological processes occupy topologically complex and dense regions of the network and correspond to its "spine" that connects all other network parts and can thus pass cellular signals efficiently throughout the network. To our knowledge, this is the first study that explores domination in the context of PPI networks.

  17. Robustness of weighted networks

    Science.gov (United States)

    Bellingeri, Michele; Cassi, Davide

    2018-01-01

    Complex network response to node loss is a central question in different fields of network science because node failure can cause the fragmentation of the network, thus compromising the system functioning. Previous studies considered binary networks where the intensity (weight) of the links is not accounted for, i.e. a link is either present or absent. However, in real-world networks the weights of connections, and thus their importance for network functioning, can be widely different. Here, we analyzed the response of real-world and model networks to node loss accounting for link intensity and the weighted structure of the network. We used both classic binary node properties and network functioning measure, introduced a weighted rank for node importance (node strength), and used a measure for network functioning that accounts for the weight of the links (weighted efficiency). We find that: (i) the efficiency of the attack strategies changed using binary or weighted network functioning measures, both for real-world or model networks; (ii) in some cases, removing nodes according to weighted rank produced the highest damage when functioning was measured by the weighted efficiency; (iii) adopting weighted measure for the network damage changed the efficacy of the attack strategy with respect the binary analyses. Our results show that if the weighted structure of complex networks is not taken into account, this may produce misleading models to forecast the system response to node failure, i.e. consider binary links may not unveil the real damage induced in the system. Last, once weighted measures are introduced, in order to discover the best attack strategy, it is important to analyze the network response to node loss using nodes rank accounting the intensity of the links to the node.

    DEFF Research Database (Denmark)

    Bøttcher, Susanne Gammelgaard

    This paper considers conditional Gaussian networks. The parameters in the network are learned by using conjugate Bayesian analysis. As conjugate local priors, we apply the Dirichlet distribution for discrete variables and the Gaussian-inverse gamma distribution for continuous variables, given...... a configuration of the discrete parents. We assume parameter independence and complete data. Further, to learn the structure of the network, the network score is deduced. We then develop a local master prior procedure, for deriving parameter priors in these networks. This procedure satisfies parameter...... independence, parameter modularity and likelihood equivalence. Bayes factors to be used in model search are introduced. Finally the methods derived are illustrated by a simple example....
