    2009-06-01

    The cotton fleahopper, Pseudatomoscelis seriatus (Reuter), is an early-season pest of developing cotton in Central Texas and other regions of the Cotton Belt. Cotton fleahopper populations develop on spring weed hosts and move to cotton as weed hosts senesce or if other weed hosts are not readily available. To identify weed hosts that were seasonably available for the cotton fleahopper in Central Texas, blooming weed species were sampled during early-season (17 March-31 May), mid-season (1 June-14 August), late-season (15 August-30 November), and overwintering (1 December-16 March) periods. The leading hosts for cotton fleahopper adults and nymphs were evening primrose (Oenothera speciosa T. Nuttall) and Mexican hat [Ratibida columnifera (T. Nuttall) E. Wooton and P. Standley], respectively, during the early season. During the mid-season, silver-leaf nightshade (Solanum elaeagnifolium A. Cavanilles) was consistently a host for fleahopper nymphs and adults. Woolly croton (Croton capitatus A. Michaux) was a leading host during the late season. Cotton fleahoppers were not collected during the overwintering period. Other suitable hosts were available before previously reported leading hosts became available. Eight previously unreported weed species were documented as temporary hosts. A compendium of reported hosts, which includes >160 plant species representing 35 families, for the cotton fleahopper is provided for future research addressing insect-host plant associations. Leading plant families were Asteraceae, Lamiaceae, and Onagraceae. Results presented here indicate a strong argument for assessing weed species diversity and abundance for the control of the cotton fleahopper in the Cotton Belt.

  9. Agriculture sows pests: how crop domestication, host shifts, and agricultural intensification can create insect pests from herbivores.

    Science.gov (United States)

    Bernal, Julio S; Medina, Raul F

    2018-04-01

    We argue that agriculture as practiced creates pests. We use three examples (Corn leafhopper, Dalbulus maidis; Western corn rootworm, Diabrotica virgifera virgifera; Cotton fleahopper, Pseudatomoscelis seriatus) to illustrate: firstly, how since its origins, agriculture has proven conducive to transforming selected herbivores into pests, particularly through crop domestication and spread, and agricultural intensification, and; secondly, that the herbivores that became pests were among those hosted by crop wild relatives or associates, and were pre-adapted either as whole species or component subpopulations. Two of our examples, Corn leafhopper and Western corn rootworm, illustrate how following a host shift to a domesticated host, emergent pests 'hopped' onto crops and rode expansion waves to spread far beyond the geographic ranges of their wild hosts. Western corn rootworm exemplifies how an herbivore-tolerant crop was left vulnerable when it was bred for yield and protected with insecticides. Cotton fleahopper illustrates how removing preferred wild host plants from landscapes and replacing them with crops, allows herbivores with flexible host preferences to reach pest-level populations. We conclude by arguing that in the new geological epoch we face, the Anthropocene, we can improve agriculture by looking to our past to identify and avoid missteps of early and recent farmers.

    The Telemetric Early Warning System Network of the Greek Atomic Energy Commission consists mainly of a network of 24 Reuter-Stokes high-pressure ionization chambers (HPIC) for gamma dose rate measurements and covers all Greece. In the present work, the response of the Reuter-Stokes HPIC to terrestrial and cosmic radiation was evaluated in comparison with spectroscopic data obtained by in situ gamma spectrometry measurements with portable hyper pure Germanium detectors (HPGe), near the Reuter-Stokes detectors and time series analysis. For the HPIC detectors, a conversion factor for the measured absorbed dose rate in air (in nGy h-1) to the total ambient dose equivalent rate Ḣ*(10), due to terrestrial and cosmic component, was deduced by the field measurements. Time series analysis of the mean monthly dose rate (measured by the Reuter-Stokes detector in Thessaloniki, northern Greece, from 2001 to 2016) was performed with advanced statistical methods (Fast Fourier Analysis and Zhao Atlas Marks Transform). Fourier analysis reveals several periodicities (periodogram). The periodogram of the absorbed dose rate in air values was compared with the periodogram of the values measured for the same period (2001-16) and in the same location with a NaI (Tl) detector which in principle is not sensitive to cosmic radiation. The obtained results are presented and discussed. © The Author 2017. Published by Oxford University Press. All rights reserved. For Permissions, please email: journals.permissions@oup.com.

    2016-03-01

    Full Text Available A market fix serves as a benchmark for foreign exchange (FX execution, and is employed by many institutional investors to establish an exact reference at which execution takes place. The currently most popular FX fix is the World Market Reuters (WM/R 4 pm fix. Execution at the WM/R 4 pm fix is a service offered by FX brokers (normally banks, who deliver execution at the fix provided they obtain the trade order ahead of time. In this paper, we study the market microstructure around 4 pm. We demonstrate that market dynamics can be distinguished from other times during the day through increased volatility and size of movements. Our findings question the aggregate benefit to the client base of using the WM/R 4 pm fix in its current form.

    In recent years a species of Hesperolabops has become a problem as a pest of nopalitos, Opuntia ficus-indica, in Milpa Alta, in the south of Mexico City, which is the most important production region of this vegetable in the country. A survey of Hesperolabops in Milpa Alta has resulted in the first report of Hesperolabops nigriceps Reuter. This occurrence should be monitored and considered in future studies in order to avoid misidentification of Hesperolabops spp. Kirkaldy native populations there, and to avoid the confusion of the damage that may be caused on O. ficus-indica.

  19. Optimal Cotton Insecticide Application Termination Timing: A Meta-Analysis.

    Griffin, T W; Zapata, S D

    2016-08-01

    The concept of insecticide termination timing is generally accepted among cotton (Gossypium hirsutum) researchers; however, exact timings are often disputed. Specifically, there is uncertainty regarding the last economic insecticide application to control fruit-feeding pests including tarnished plant bug (Lygus lineolaris (Palisot de Beauvois)), boll weevil (Anthonomus grandis), bollworm (Helicoverpa zea), tobacco budworm (Heliothis virescens), and cotton fleahopper (Pseudatomoscelis seriatus). A systematic review of prior studies was conducted within a meta-analytic framework. Nine publicly available articles were amalgamated to develop an optimal timing principle. These prior studies reported 53 independent multiple means comparison field experiments for a total of 247 trial observations. Stochastic plateau theory integrated with econometric meta-analysis methodology was applied to the meta-database to determine the shape of the functional form of both the agronomic optimal insecticide termination timing and corresponding yield potential. Results indicated that current university insecticide termination timing recommendations are later than overall estimated timing suggested. The estimated 159 heat units (HU) after the fifth position above white flower (NAWF5) was found to be statistically different than the 194 HU termination used as the status quo recommended termination timing. Insecticides applied after 159 HU may have been applied in excess, resulting in unnecessary economic and environmental costs. Empirical results also suggested that extending the insecticide termination time by one unit resulted in a cotton lint yield increase of 0.27 kilograms per hectare up to the timing where the plateau began. Based on economic analyses, profit-maximizing producers may cease application as soon as 124 HU after NAWF5. These results provided insights useful to improve production systems by applying inputs only when benefits were expected to be in excess of the

  20. Stochastic dynamics of phase singularities under ventricular fibrillation in 2D Beeler-Reuter model

    2011-09-01

    Full Text Available The dynamics of ventricular fibrillation (VF has been studied extensively, and the initiation mechanism of VF has been elucidated to some extent. However, the stochastic dynamical nature of sustained VF remains unclear so far due to the complexity of high dimensional chaos in a heterogeneous system. In this paper, various statistical mechanical properties of sustained VF are studied numerically in 2D Beeler-Reuter-Drouhard-Roberge (BRDR model with normal and modified ionic current conductance. The nature of sustained VF is analyzed by measuring various fluctuations of spatial phase singularity (PS such as velocity, lifetime, the rates of birth and death. It is found that the probability density function (pdf for lifetime of PSs is independent of system size. It is also found that the hyper-Gamma distribution serves as a universal pdf for the counting number of PSs for various system sizes and various parameters of our model tissue under VF. Further, it is demonstrated that the nonlinear Langevin equation associated with a hyper-Gamma process can mimic the pdf and temporal variation of the number of PSs in the 2D BRDR model.

  1. Co-word analysis for the non-scientific information example of Reuters Business Briefings

    2006-01-01

    Full Text Available Co-word analysis is based on a sociological theory developed by the CSI and the SERPIA (Callon, Courtial, Turner, 1991 in the mid eighties. This method, originally dedicated to scientific fields, measures the association strength between terms in documents to reveal and visualise the evolution of scientific fields through the construction of clusters and strategic diagram. This method has since been successfully applied to investigate the structure of many scientific areas. Nowadays it occurs in many software systems which are used by companies to improve their business, and define their strategy but its relevance to this kind of application has not been proved yet. Using the example of economic and marketing information on DSL technologies from Reuters Business Briefing, this presentation gives an interpretation of co-word analysis for this kind of information. After an overview of the software we used (Sampler and after an outline of the experimental protocol, we investigate and explain each step of the co-word analysis process: terminological extraction, computation of clusters and the strategic diagram. In particular, we explain the meaning of each parameter of the method: the choice of variables and similarity measures is discussed. Finally we try to give a global interpretation of the method in an economic context. Further studies will be added to this work in order to allow a generalisation of these results.

    Full Text Available Julia REUTER's latest book, "Geschlecht und Körper" [Gender and Body], contains ten studies on these two central concepts in sociology, as well as lending consideration to visuality and otherness. The author focuses on theories of performance, discourse and practice, which are used both as analytical tools and, reflexively, as objects of analysis. The book offers rich descriptions of the two central concepts, but does not fundamentally deal with how they interrelate. It offers a vivid account of current themes and discussions.

    Full Text Available In tropical forests, tree ferns constitute an important phorophyte for the establishment and occurrence of epiphytic species. Composition, structure and vertical distribution of epiphytic ferns were studied on Alsophila setosa Kaulf., in a semideciduous seasonal forest fragment, in the city of Morro Reuter (29º32'07"S and 51º05'26"W, in the state of Rio Grande do Sul, Brazil. The sample consisted of 60 caudices of at least 4 m high, which were divided in 1 m intervals from the ground. The specific importance value was estimated trough the coverage value and caudex frequency at the intervals. A total of 14 species was recorded, belonging to 10 genera and five families. The highest specific richness occurred in Polypodiaceae. The rarefaction curve for the total sample did not reach an asymptote with an estimated 14.98 to 16.95 species, showing that a few species could still be recorded. The species with the highest importance value and vertical amplitude was Blechnum binervatum (Poir. C.V. Morton & Lellinger, with a decreasing frequency from bottom to top of the caudex. Considering the predominance of habitual holoepiphytes, the removal of Alsophila setosa caudices compromises microhabitat availability for epiphytes in the forest understory.Nas florestas tropicais as samambaias arborescentes constituem forófitos importantes para o estabelecimento e ocorrência de espécies epifíticas.

    Full Text Available Abstract Background It is rare to find terrestrial nematode lineages parasitizing arthropods inhabiting the intertidal or littoral zone of the oceans. During an ecological study along the Oregon dunes, an allantonematid nematode (Tylenchomorpha: Allantonematidae was discovered parasitizing the intertidal shore bug, Saldula laticollis (Reuter(Hemiptera: Saldidae. This shore bug is adapted to an intertidal environment and can survive short periods of submergence during high tides. The present study describes the nematode parasite and discusses aspects of its development, ecology and evolution. Methods Adults and last instar nymphs of S. laticollis (Hemiptera: Saldidae were collected from the high intertidal zone among clumps of Juncus L. (Juncaceae plants at Waldport, Oregon on October 3, 2011. The bugs were dissected in 1% saline solution and the nematodes killed in 1% Ringers solution and immediately fixed in 5% formalin (at 20°C. Third stage juveniles removed from infected hosts were maintained in 1% saline solution until they matured to the adult stage, molted and mated. Results Halophilanema prolata n. gen., n. sp. (Nematoda: Allantonematidae is described from last instar nymphs and adults of the intertidal bug, Saldula laticollis on the Oregon coast. The new genus can be distinguished from other genera in the Allantonematidae by a stylet lacking basal knobs in both sexes, an excretory pore located behind the nerve ring, ribbed spicules, a gubernaculum, the absence of a bursa and the elongate-tubular shape of the ovoviviparous parasitic females. Studies of the organogenesis of Halophilanema showed development to third stage juveniles in the uterus of parasitic females. Maturation to the free-living adults and mating occurred in the environment. The incidence of infection of S. laticollis ranged from 0% to 85% depending on the microhabitat in the intertidal zone. Conclusions Based on the habitat and morphological characters, it is proposed

  7. An assessment of South Africa's research journals: Impact factors, Eigenfactors and structure of editorial boards

    Directory of Open Access Journals (Sweden)

    Androniki E.M. Pouris

    2015-03-01

    Full Text Available Scientific journals play an important role in academic information exchange and their assessment is of interest to science authorities, editors and researchers. The assessment of journals is of particular interest to South African authorities as the country's universities are partially funded according to the number of publications they produce in accredited journals, such as the Thomson Reuters indexed journals. Scientific publishing in South Africa has experienced a revolution during the last 10 years. Our objective here is to report the performance of the country's journals during 2009 and 2010 according to a number of metrics (i.e. impact factors, Eigenfactors and the international character of editorial boards; to identify and compare the impact of the South African journals that have been recently added to the Thomson Reuters' Journal Citation Reports; and to elaborate on issues related to science policy.

  16. Performance of B-10 based detectors

    Energy Technology Data Exchange (ETDEWEB)

    Boucher, Mathieu; Anderson, Tom; Johnson, Nathan; Mckinny, Kevin; Mcpheeters, Matthew [GE Measurement and Control - Reuter-Stokes, Twinsburg, Ohio (United States)

    2015-07-01

    Helium-3 gas-filled detectors have been used in nuclear safeguards applications, in homeland security neutron detection modules and in research for over 30 years. With the current shortage of {sup 3}He gas, GE's Reuter-Stokes business developed a {sup 10}B lined proportional counter and a {sup 10}B hybrid detector, in which a small amount of {sup 3}He is added to a 10B detector to enhance the neutron sensitivity. In 2010, GE's Reuter-Stokes successfully developed a commercial alternative to 3He gas-filled detectors for homeland security neutron detection modules based on 10B lined proportional counters. We will present the concept behind the {sup 10}B neutron detection modules, as drop-in replacement to existing 3He neutron detection modules deployed, and the timeline and development needed to get a fully commercial application. To ensure the highest quality, each {sup 10}B neutron detection unit is put through a series of tests: temperature cycles from -40 deg. C to +55 deg. C, vibration testing at levels up to 2.5 g from 10 Hz to 50 Hz in every direction, neutron sensitivity reaching up to 4.5 cps/(ng {sup 252}CF at 2 m), and gamma insensitivity with field reaching 1 Sv/hr. In 2013, GE's Reuter-Stokes developed the B10Plus+{sup R} detector, in which a small amount of {sup 3}He is added to a {sup 10}B lined proportional counter. Depending on the amount of {sup 3}He added, the B10Plus+{sup R} can more than double the neutron sensitivity compared to a {sup 10}B lined proportional counter. {sup 10}B lined proportional counters and B10Plus+{sup R} have excellent gamma rejection and excellent performance even at very high neutron flux. The gamma rejection and high neutron flux performance of these detectors are comparable, if not better, than traditional {sup 3}He proportional counters. GE's Reuter-Stokes business modelled, designed, built and tested prototype coincidence counters using the {sup 10}B lined detectors and the {sup 10}B hybrid

    Full Text Available Globalization of the capital markets increasingly leads the investors to understand the fundamentals and technicals of asset cross-correlations and the global asset allocation seems to be an important task. The paper measures product momentum correlations between the four leading global benchmarks Standard & Poor’s stock index, Thomson Reuters/Jefferies CRB index, 30-Year U.S. Treasury Bond Price index and Dollar Index and between these indices and the Czech stock PX index. Empirical results illustrate that statistically significant correlations between U.S. indices existed over some past period at the 95.0% confidence level. In addition, the significant relation between indices Standard & Poor’s stock index, Thomson Reuters/Jefferies CRB index and the Czech stock market PX during the past fifteen years has been detected. These conclusions were reached from an analysis of monthly data in the United States and the Czech Republic, from January 1999 to April 2014. The empirical results offer beneficial applications not only for investors to diversify their risk but also for policy-makers to allocate resources more efficiently.

  4. A combined road weather forecast system to prevent road ice formation in the Adige Valley (Italy)

    Science.gov (United States)

    Di Napoli, Claudia; Piazza, Andrea; Antonacci, Gianluca; Todeschini, Ilaria; Apolloni, Roberto; Pretto, Ilaria

    2016-04-01

    Road ice is a dangerous meteorological hazard to a nation's transportation system and economy. By reducing the pavement friction with vehicle tyres, ice formation on pavements increases accident risk and delays travelling times thus posing a serious threat to road users' safety and the running of economic activities. Keeping roads clear and open is therefore essential, especially in mountainous areas where ice is likely to form during the winter period. Winter road maintenance helps to restore road efficiency and security, and its benefits are up to 8 times the costs sustained for anti-icing strategies [1]. However, the optimization of maintenance costs and the reduction of the environmental damage from over-salting demand further improvements. These can be achieved by reliable road weather forecasts, and in particular by the prediction of road surface temperatures (RSTs). RST is one of the most important parameters in determining road surface conditions. It is well known from literature that ice forms on pavements in high-humidity conditions when RSTs are below 0°C. We have therefore implemented an automatic forecast system to predict critical RSTs on a test route along the Adige Valley complex terrain, in the Italian Alps. The system considers two physical models, each computing heat and energy fluxes between the road and the atmosphere. One is Reuter's radiative cooling model, which predicts RSTs at sunrise as a function of surface temperatures at sunset and the time passed since then [2]. One is METRo (Model of the Environment and Temperature of Roads), a road weather forecast software which also considers heat conduction through road material [3]. We have applied the forecast system to a network of road weather stations (road weather information system, RWIS) installed on the test route [4]. Road and atmospheric observations from RWIS have been used as initial conditions for both METRo and Reuter's model. In METRo observations have also been coupled to

  7. How have the Eastern European countries of the former Warsaw Pact developed since 1990? A bibliometric study.

    Science.gov (United States)

    Kozak, Marcin; Bornmann, Lutz; Leydesdorff, Loet

    Did the demise of the Soviet Union in 1991 influence the scientific performance of the researchers in Eastern European countries? Did this historical event affect international collaboration by researchers from the Eastern European countries with those of Western countries? Did it also change international collaboration among researchers from the Eastern European countries? Trying to answer these questions, this study aims to shed light on international collaboration by researchers from the Eastern European countries (Russia, Ukraine, Belarus, Moldova, Bulgaria, the Czech Republic, Hungary, Poland, Romania, and Slovakia). The number of publications and normalized citation impact values are compared for these countries based on InCites (Thomson Reuters), from 1981 up to 2011. The international collaboration by researchers affiliated to institutions in Eastern European countries at the time points of 1990, 2000 and 2011 was studied with the help of Pajek and VOSviewer software, based on data from the Science Citation Index (Thomson Reuters). Our results show that the breakdown of the communist regime did not lead, on average, to a huge improvement in the publication performance of the Eastern European countries and that the increase in international co-authorship relations by the researchers affiliated to institutions in these countries was smaller than expected. Most of the Eastern European countries are still subject to changes and are still awaiting their boost in scientific development.

    The generic name Lanchnophorus Reuter, 1887, deemed for a long time to be unavailable as incorrect original spelling of Lachnophorus (in fact Lachnophorus Distant, 1903 is an unjustified emendation of the former), is restored as a valid name of the genus. Lachnesthus Bergroth, 1915, syn. nov. (new name for the preoccupied Lachnophorus Distant, 1903) is considered junior synonym of Lanchnophorus. The following nomenclatural changes are proposed: Lanchnophorus flavus (Scudder, 1971) comb. nov. = Lachnesthus chinai Scudder, nomen nudum; Lanchnophorus guttulatus Reuter, 1887, comb. restit. = Lachnophorus albidomaculatus Distant, 1913, syn. nov. = Lachnesthus rodriguezensis China, 1925, syn. nov.; Lanchnophorus leucospilus (Walker, 1872) comb. nov.; Lanchnophorus merula (Distant, 1903) comb. nov.; and Lanchnophorus singalensis (Dohrn, 1860) comb. nov. Three new species are described: Lanchnophorus gaoqingae Kment & Jindra sp. nov. from China (Yunnan), Lanchnophorus seminitens Kment & Carapezza sp. nov. from Socotra Island (Yemen), and Lanchnophorus webbi Kondorosy sp. nov. from India: Tamil Nadu. Bibliographies and known distribution of all the included species are reviewed. The following new country and state records are provided: L. flavus from Central African Republic, Ethiopia, Ghana, Mali, Malawi, Niger, Zambia and Zimbabwe; L. leucospilus from China (Yunnan) and Laos, L. merula from India (Kerala/Tamil Nadu) and Thailand; L. singalensis from Angola, Benin, Mozambique, Namibia, Senegal, Sierra Leone, Tanzania, Togo, Uganda, Zambia, Zimbabwe, China (Hainan), Iran (Sistan and Ba-luchestan), Oman, Pakistan, India (Himachal Pradesh, Karnataka, Kerala, Rajasthan), Malaysia, Philippines, and Thailand.

    Visa, Ari J. E.; Toivonen, Jarmo; Autio, Sami; Maekinen, Jarno; Back, Barbro; Vanharanta, Hannu

    2001-03-01

    It is common that text documents are characterized and classified by keywords that the authors use to give them. Visa et al. have developed a new methodology based on prototype matching. The prototype is an interesting document or a part of an extracted, interesting text. This prototype is matched with the document database of the monitored document flow. The new methodology is capable of extracting the meaning of the document in a certain degree. Our claim is that the new methodology is also capable of authenticating the authorship. To verify this claim two tests were designed. The test hypothesis was that the words and the word order in the sentences could authenticate the author. In the first test three authors were selected. The selected authors were William Shakespeare, Edgar Allan Poe, and George Bernard Shaw. Three texts from each author were examined. Every text was one by one used as a prototype. The two nearest matches with the prototype were noted. The second test uses the Reuters-21578 financial news database. A group of 25 short financial news reports from five different authors are examined. Our new methodology and the interesting results from the two tests are reported in this paper. In the first test, for Shakespeare and for Poe all cases were successful. For Shaw one text was confused with Poe. In the second test the Reuters-21578 financial news were identified by the author relatively well. The resolution is that our text mining methodology seems to be capable of authorship attribution.

  20. Climate change and biometeorology, the International Society of Biometeorology and its journal: a perspective on the past and a framework for the future

    Science.gov (United States)

    Beggs, Paul John

    2014-01-01

    Anthropogenic climate change is inherently a biometeorological issue. As such, it would be reasonably expected that the International Society of Biometeorology (ISB) and its journal, International Journal of Biometeorology ( IJB), would have had climate change feature prominently in their activities, articles etc., and to therefore have made a substantial and valuable contribution to the science of the issue. This article presents an analysis of climate change science in ISB and IJB. The analysis focusses on climate-change-related publications by ISB Presidents found through searches of Thomson Reuters Web of Science; contributions to the Intergovernmental Panel on Climate Change's (IPCC's) Working Group II (WGII) by ISB Presidents; and climate change-related publications in IJB found through searches of Thomson Reuters Web of Science. The results demonstrate that the ISB, as represented by its recent, current, and future Presidents, is actively engaged in climate change research and the production of scholarly climate change publications. For example, ISB Presidents have contributed as authors to all four IPCC WGII Assessment Reports, with some Presidents having contributed to more than one Assessment Report or several chapters of the one report. Similarly, it is evident that the IJB is increasingly attracting and publishing climate-change-related articles, with such articles generally having greater impact (as indicated by citations) than other IJB articles. Opportunities for the ISB to provide an internal framework for, and showcase, its climate change work are described. Such opportunities, if enacted, would complement the recent creation of two IJB climate change Field Editor positions.

    2013-02-01

    As highlighted in the first part of this review published last month, the year 2012 saw the approval of a remarkable number of new drugs, and among the new drugs reaching the market, a significant proportion were orphan drugs developed for treating less prevalent diseases. These drugs are certainly not expected to become blockbusters, but are of high interest because of their efficacy in a narrow spectrum of patients. This trend aligns with the general tendency of staying away from fit-for-all blockbusters into personalized medicine as one of the strategies for overcoming the patent cliff that resulted in a long list of drugs going off patent and being approved as generics also during last year. The emerging scenario resulting from new developments in the form of new drugs and biosimilars and newly available generic medications paralleled by strategic movements within the pharmaceutical industry to reinforce their position in the market, as reflected by merger and acquisition deals accompanied by significant efforts into prioritization resulting in spin-off and split transactions, is reviewed in this second part. This paper includes a significant amount of data in tables for quick review and to profile the new strategic movements in drug pipelines. Further information, including details on mechanisms of action, current status, itemized pharmacology, pharmacokinetic and clinical trial research findings and updated information can be found in the proprietary databases Thomson Reuters Integrity(SM) and Thomson Reuters Cortellis™.

Para esta análise, utilizaremos o conceito de “perspectivas narrativas”, desenvolvido por Reuter (2011, o qual propõe que a narrativa se estrutura a partir de determinado prisma, ou seja, o narrador narra através de determinado ponto de vista, deixando marcas de sua percepção. Em nossa proposta de trabalho, relacionaremos a ideia de Reuter aos pressupostos de Iser (1999 sobre a indeterminação na prosa de ficção, teoria através do qual o estudioso nos mostra como todo texto ficcional é construído sobre uma estrutura lacunar, cujos vazios e subentendidos evocam a participação do leitor e cumprem, assim, uma função estética. Ambos diretores, assim, preenchem vazios, concretizando obras como leitores. O objetivo do estudo é mostrar que as duas adaptações de A fantástica fábrica de chocolate distinguem-se pelo ponto de vista da narração, inclusive pela perspectiva do tempo da diegese e, ainda, pelos distintos efeitos que desejam causar – efeitos esses que incluem a abertura para novas lacunas, como num contínuo jogo de interpretação.

    Full Text Available Journals’ impact indicators are not comparable among scientific fields because of systematic differences in publication and citation habits. In this work, the impact factor was decomposed into five independent variables, as applied to journal category, fields, and areas considered in the databases of the leading provider of science indicators, Thomson Reuters. A Principal Component Analysis was employed to find the sources of the variance and a Cluster Analysis was used to detect similarities. In spite of systematic differences between disciplines, the principal components explain 78% of the total variance. From the statistical point of view, some categories of Science are closer to the Social Sciences than to Science and vice versa.Los indicadores de impacto de revistas no son comparables entre campos científicos debido a las diferencias significativas en los hábitos de publicación y citación. En este trabajo se presenta una descomposición del factor de impacto en cinco variables independientes. Esta descomposición se aplica a las categorías de revista, campos y áreas considerados en las bases de datos del principal proveedor de indicadores científicos, Thomson Reuters. Para localizar las fuentes de la varianza se emplea un Análisis de Componentes Principales y para detectar las semejanzas se utiliza un Análisis Cluster. A pesar de las diferencias sistemáticas entre disciplinas, las componentes principales explican el 78% de la varianza total. Existen categorías de Ciencias que están más próximas, desde el punto de vista estadístico, de algunas Ciencias Sociales que del resto de Ciencias y viceversa.

    The screen dealing system provides a facility whereby buyers and sellers of spot thermal coal can make bids and offers via the medium of the Reuters screen. A sale results when a market participant notifies his acceptance of a price to a central dealing desk. Use of the system is available to all genuine participants in the coal trade. This paper reports that it provides a focus for information and for the visible making of coal prices. For years screen trading has been used successfully to trade other commodities. At last coal is being traded electronically. It makes sense. It works. Users like it

  12. NucNet's growing impact on the media - Now the official figures

    1998-01-01

    Net's impact on the news media has had to be almost completely anecdotal. Now, thanks to a comparatively new database search facility, the NucNet Central Office team is able to track instances in which NucNet has been quoted as the source for a news story or magazine article. The database is run by Reuters, but contains information from a wide range of other news sources, such as national news agencies and major national newspapers. A search of the database, carried out on December 10th 1997, produced 42 cases of NucNet being quoted by name over the previous three years. There were five in 1995, 13 in 1996, and 24 in 1997. No fewer than 15 of the 24 cases in 1997 occurred in the preceding six months. It takes no great mathematician to see that each annual figure is roughly double that of the preceding 12-month period. We can at least see every instance of NucNet being quoted by Reuters, but this of course does not cover the other major international news agencies, such as the Associated Press, UPI and AFP. This underlines the fact that NucNet Central Office and the NucNet Board rely heavily on individual network members spontaneously reporting examples of media use. The results obtained recently, showing regular and fairly frequent use by Reuters and the print media, but the figures do not give the full picture. If the database, known as Reuters Business Briefing, acts as some sort of barometer measuring NucNet's impact on the news media, we cannot say exactly what the weather is like - but at least we can say that the barometer reading is on the increase. And for once we can give definite figures. (author)

  13. A Unique Publication Model that Works

    Full Text Available Rambam Maimonides Medical Journal was once a new and unknown publication. Today we have more than 17,000 subscribers from 146 nations and territories. We published 39 scientific medical papers in 2017 out of 61 submitted manuscripts. We are now indexed by PubMed and Thompson Reuters Emerging Sources Citation Index, to name a few. Next year, the Journal is scheduled to receive an official impact factor from Thompson Reuters. We are not so unknown anymore. As a new Journal, most of the papers submitted were naturally reviews. However, the most important aspect for the promotion and advancement of medicine is publication of original research. To promote such efforts the editors of Rambam Maimonides Medical Journal established in 2017 the Maimonides Best Published Original Research Prize. This annual prize of $1,000 is to be awarded to the first author of the best original research paper published in the journal over the previous year. This prize is an added benefit to authors. Since asking for fees from authors who have few or no research funds or grants may preclude publication of their papers, our Journal has no subscription fees, no submission fees, and no publication fees. Equally noteworthy is that although published by Rambam Health Care Campus, the Journal is unaffiliated with any organization or society. A decision was also made when the Journal was established to seek no advertising—perhaps the most unusual feature of this publication. Rambam Maimonides Medical Journal is donor-supported by those who share in our vision to ensure that anyone anywhere in the world can submit their scholarly work with no fear of commercial bias and no fees to impede publication.

    Full Text Available The paper develops a comprehensive framework for market risk stress testing in internationally active financial institutions. We begin by defining the scope and type of the stress test and explaining how to select risk factors and the stress time horizon. We then address challenges related to data gathering, followed by in-depth discussion of techniques for developing realistic shock scenarios. Next the process of shock application to a particular portfolio is described, followed by determination of portfolio profit and loss. We conclude by briefly discussing the issue of assigning probability to stress scenarios. We illustrate the framework by considering the development of a ‘worst case’ scenario using global financial market data from Thomson Reuters Datastream.

    Brucellosis is one of the most frequent zoonosis in most parts of the world. This zoonosis remains a great problem to public health in developing countries, although developed countries have successfully controlled it. Mexico still shows a high annual brucellosis incidence in humans; thus, the country is considered around the world as an endemic brucellosis country. To describe the connection/association between this zoonosis and the current epidemiological situation in the Mexican population. Perusal of research reports, epidemiological studies and veterinarian reviews performed in Mexico, using data bases such as PubMed, Thompson Reuters, Mesh research. The risk of infection by Brucella in Mexico is associated with the consumption of unpasteurized dairy products, mainly fresh cheeses.

    Psoriasis is a relevant topic for publication in general medical journals. We conducted a search of the Thomson Reuters' Science Citation using the search term of "psoriasis" in five high-impact general medical journals. All citation classics from 1970 to 2012 were included and each author's total number of citations was summated. A total of 51 citation classics were collected. The most common topic of publication was psoriasis treatment (37), especially biologic agents (16). A total of 1037 authors of psoriasis articles were identified in our study and the top 25 most-cited authors were compiled. We hope our citation analysis provides a historical perspective and highlights the work of our colleagues and predecessors.

    Full Text Available We present a taxonomic study of the representatives or Euphorbia subsect. Esula in the Iberian Peninsula. Prior to this, a first section is included on the study of the leaf surface and a second section on chromosome numbers.
    The section on leaf surface is based on a study of the leaves or 45 populations of Iberian and European taxa of the subsections using a light microscope and SEM. The characters analyzed are cell shape, morphology of the cells and stomata (primary and secondary sculpture and epicuticular waxes (tertiary sculpture. Some microcharacters of the leaf surface proved particularly usefu1for taxonomical purposes. Thus the basic type of stoma and the distribution model of the stomata on the two sides of the leaf are characters which make it possible to separate taxa as closely related as E. esula L. subsp. esula and E. esula L. subsp orientalis (Boiss. in DC. Molero & Rovira. The morphological type of the epicuticular waxes also enables us to differentiate between E.graminifolia Vill. and E. esula aggr. And to distinguish subsp. bolosii Molero & Rovira from the remaining subespecies in E. nevadensis Boiss. & Reuter.
    Cytogenetic investigation reveals the presence of only the diploid cytotype (2n=10 in E. cyparissias L. and E. esula L. subsp. esula in the Iberian Peninsula. We describe for the first time in E. nevadensis s.1. a polyploidy complex with a base of x= 10 in which the diploid level (2n=20 is present in all subspecies; the tetraploid level (2n=40 is present in E. nevadensis subsp. nevadensis and the hexaploid level (2n=60 is found in E. nevadensis subsp. bolosii. Chromosome number is not a parameter that can be used for taxonomic purposes. In E. nevadensis, cytogenetic differentiation has followed its own course, with no apparent relationship to the process of morphological

    A longitudinal bibliometric analysis of publications indexed in Thomson Reuters' Incites and Elsevier's Scopus, and published from the Arab Gulf States and neighbouring countries, shows clear effects of major political events during the past 35 years. Predictions made in 2006 by the US diplomat Richard N. Haass on political changes in the Middle East have come true in the Gulf States’ national scientific research systems, to the extent that Iran has become in 2015 by far the leading country in the Arab Gulf, and South-East Asian countries including China, Malaysia and South Korea have become major scientific collaborators, displacing the USA and other large Western countries. But collaborations patterns among Gulf States show no apparent relationship with differences in Islam denominations. (Author)

First, we document the phenomenon that we label “Jam-the-Close”: The last half hour of trading (15:30 to 16:00 EST contains a substantial and statistically significant amount of news sentiment releases. This finding is robust across years and months of the year. Next, upon further investigations we found that the “novelty” score is on average 0.67 in this period vs. 2.09 prior to midday. This indicates that “new” news is flowing at a rapid pace prior to the close. Finally, we discuss the implication of such phenomena in the context of existing financial literature.

    Publishing articles in a prestigious journal is a golden rule for university professors and researchers nowadays. Impact factor, journal rank, and citation count, included in Science Citation Index managed by Thomson Reuters Web of Science, are the most important indicators for evaluating the quality of academic journals. By listing the journals encompassed in the "Integrative and Complementary Medicine" category of Science Citation Index from 2003 to 2013, this paper examines the publication trends of journals in the category. The examination includes number, country of origin, ranking, and languages of journals. Moreover, newly listed or removed journals in the category, journal publishers, and open access strategies are examined. It is concluded that the role of journal publisher should not be undermined in the "Integrative and Complementary Medicine" category.

    2012-01-01

    The study conducted in different bioclimatic areas, has revealed that mites particularly Oribatida present a staggering distribution inspace and time in correlation with the improvement of the ecological conditions.The arid and semi-arid areas constitute a less favorable environment in contrast tothe humid and sub humid zones which are characterised by a more favorable variety of vegetation and climatic conditions. These conditions constitute a favorable environment for the development of mites especially Oribati. There are 6 species in arid zones, 11 species in semi-arid zones and 30 in wetlands and sub-humid areas. This hierarchical classification of mites stands is in good agreement with the environmental conditions which prevail in this region. However, it can be noted that the behavior of mites species manifests itself differently. Certain species show tolerance to these variations and their distribution area is important and very large. On the contrary, the majority of species whose distribution area is limited are very demanding vis-a-vis these conditions. Their presence requires some moisture in the environment and an adequate nutritional support (litter). It constitutes an important biological indicator since it helps in understanding the natural or anthropogenic changes that can alter the environment. (author)

    Full Text Available Abstract Background Adults with certain comorbid conditions have a higher risk of pneumonia than the overall population. If treatment of pneumonia is more costly in certain predictable situations, this would affect the value proposition of populations for pneumonia prevention. We estimate the economic impact of community-acquired pneumonia (CAP for adults with asthma, diabetes, chronic obstructive pulmonary disease (COPD and congestive heart failure (CHF in a large U.S. commercially-insured working age population. Methods Data sources consisted of 2003 through 2007 Thomson Reuters MarketScan Commercial Claims and Encounters and Thomson Reuters Health Productivity and Management (HPM databases. Pneumonia episodes and selected comorbidities were identified by ICD-9-CM diagnosis codes. By propensity score matching, controls were identified for pneumonia patients. Excess direct medical costs and excess productivity cost were estimated by generalized linear models (GLM. Results We identified 402,831 patients with CAP between 2003 through 2007, with 25,560, 32,677, 16,343, and 5,062 episodes occurring in patients with asthma, diabetes, COPD and CHF, respectively. Mean excess costs (and standard error, SE of CAP were $14,429 (SE=44 overall. Mean excess costs by comorbidity subgroup were lowest for asthma ($13,307 (SE=123, followed by diabetes ($21,395 (SE=171 and COPD ($23,493 (SE=197; mean excess costs were highest for patients with CHF ($34,436 (SE=549. On average, indirect costs comprised 21% of total excess costs, ranging from 8% for CHF patients to 27% for COPD patients. Conclusions Compared to patients without asthma, diabetes, COPD, or CHF, the excess cost of CAP is nearly twice as high for patients with diabetes and COPD and nearly three times as high for patients with CHF. Indirect costs made up a significant but varying portion of excess CAP costs. Returns on prevention of pneumonia would therefore be higher in adults with these comorbidities.

    Since 2011, drug market participants have traded illegal drugs through cryptomarkets, a user-friendly infrastructure in which drug market participants can conduct business transactions. This study assesses market competition and the size and scope of drug vendors' activities on one of the largest cryptomarkets, AlphaBay, in order to better understand the challenges that drug vendors face when selling on this venue. Relying on data collected from AlphaBay, we calculate the degree of competition within the drug market using the Herfindhal-Hirshmann Index (HHI). We then follow a micro analytical approach and assess the size and scope of vendors' accounts. This is done by evaluating each vendor's market share over time using a group-based trajectory model (GBTM). Results from the GBTM are then used to assess vendors' exposure, diversity and experience based on their selling position in the market. The HHI scores demonstrate that cryptomarkets offer a highly competitive environment that fits in a top-heavy market structure. However, the distribution of vendors' market share trajectories shows that only a small portion of vendors (referred to as high-level vendors) succeed in generating regular sales, whereas the majority of vendors are relegated to being mere market spectators with almost zero sales. This inequality is exacerbated by the aggressive advertising of high-level vendors who post many listings. Overall, product diversity and experience is limited for all market participants regardless of their level of success. We interpret these results through Reuter's work on traditional illegal markets, e-commerce studies and the growing field of cryptomarket research. We conclude that, while offering a new venue for illegal drug transactions, in many ways, the economics of cryptomarkets for drug dealing are consistent with Reuter's classic assessment of illegal markets and the consequences of product illegality that underlie it. Cryptomarkets conflicting features, a

    One of the successfully tested methods to design genetically engineered cardiac pacemaker cells consists in transfecting a human mesenchymal stem cell (hMSC) with a HCN2 gene and connecting it to a myocyte. We develop and study a mathematical model, describing a myocyte connected to a hMSC transfected with a HCN2 gene. The cardiac action potential is described both with the simple Beeler Reuter model, as well as with the elaborate dynamic Luo Rudy model. The HCN2 channel is described by fitting electrophysiological records, in the spirit of Hodgkin Huxley. The model shows that oscillations can occur in a pair myocyte-stem cell, that was not observed in the experiments yet. The model predicted that: (1) HCN pacemaker channels can induce oscillations only if the number of expressed I channels is low enough. At too high an expression level of I channels, oscillations cannot be induced, no matter how many pacemaker channels are expressed. (2) At low expression levels of I channels, a large domain of values in the parameter space (n, N) exists, where oscillations should be observed. We denote N the number of expressed pacemaker channels in the stem cell, and n the number of gap junction channels coupling the stem cell and the myocyte. (3) The expression levels of I channels observed in ventricular myocytes, both in the Beeler Reuter and in the dynamic Luo Rudy models are too high to allow to observe oscillations. With expression levels below ˜1/4 of the original value, oscillations can be observed. The main consequence of this work is that in order to obtain oscillations in an experiment with a myocyte-stem cell pair, increasing the values of n, N is unlikely to be helpful, unless the expression level of I has been reduced enough. The model also allows us to explore levels of gene expression not yet achieved in experiments, and could be useful to plan new experiments, aimed at improving the robustness of the oscillations.

    We propose a cluster based classification model for suspicious email detection and other text classification tasks. The text classification tasks comprise many training examples that require a complex classification model. Using clusters for classification makes the model simpler and increases...... the accuracy at the same time. The test example is classified using simpler and smaller model. The training examples in a particular cluster share the common vocabulary. At the time of clustering, we do not take into account the labels of the training examples. After the clusters have been created......, the classifier is trained on each cluster having reduced dimensionality and less number of examples. The experimental results show that the proposed model outperforms the existing classification models for the task of suspicious email detection and topic categorization on the Reuters-21578 and 20 Newsgroups...

    Although bibliometric analysis affords significant insight into the progression and distribution of information within a particular research field, detailed longitudinal studies of this type are rare within the field of nursing. This study aimed to investigate, from a bibliometric perspective, the progression and trends of core international nursing journals over the longest possible time period. A detailed bibliometric analysis was undertaken among 7 core international nursing periodicals using custom historical data sourced from the Thomson Reuters Journal Citation Reports®. In the 32 years between 1977 and 2008, the number of citations received by these 7 journals increased over 700%. A sustained and statistically significant (pnursing. Impressive and continual impact factor gains suggest that published nursing research is being increasingly seen, heard and cited in the international academic community.

    The average costs of Musculoskeletal Disorder (MSD) and odds ratios for filing medical claims related to MSD were examined. The medical claims were identified by ICD 9 codes for four US Census regions within retail trade. Large private firms' medical claims data from Thomson Reuters Inc. MarketScan databases for the years 2003 through 2006 were used. Average costs were highest for claims related to lumbar region (ICD 9 Code: 724.02) and number of claims were largest for low back syndrome (ICD 9 Code: 724.2). Whereas the odds of filing an MSD claim did not vary greatly over time, average costs declined over time. The odds of filing claims rose with age and were higher for females and southerners than men and non-southerners. Total estimated national medical costs for MSDs within retail trade were $389 million (2007 USD).

    The green miridbug, Cyrtorhinus lividipennis, an important natural enemy of the rice brown planthopper (BPH), Nilaparvata lugens plays a major role as a predator in suppressing the pest population. The study assessed the impact of certain potential insecticides used in the rice ecosystem on the miridbug predator and brown planthopper through contact toxicity. Eleven insecticides, including neonicotinoids, diamides, azomethine pyridines, carbamates, pyrethroids, organophosphates and cyclodienes were selected to test their toxicities against the nymphs of C. lividipennis and N. lugens. Median lethal concentration (LC(50)) was determined for each insecticide using an insecticide-coated vial (scintillation) residue bioassay, which revealed BPMC as the highly toxic chemical with an LC(50) of 0.003mga.iL(-1) followed by ethofenprox and clothianidin with LC(50) of 0.006mga.iL(-1) at 48 HAT against C. lividipennis and ethofenprox as the highly toxic chemical with an LC(50) of 0.009mga.iL(-1) followed by clothianidin with an LC(50) of 0.211mga.iL(-1) at 48h after treatment (HAT) against N. lugens. Among the insecticides tested, the cyclodiene compound, endosulfan had the lowest acute contact toxicity (LC(50)=66.65mga.iL(-1) at 48 HAT) to C. lividipennis. Among the insecticides tested, endosulfan, chlorpyriphos, acephate and methyl parathion are regarded as safer to C. lividipennis based on selectivity ratio, hazard quotient and probit substitution method of risk assessments. 2010 Elsevier Ltd.

    This study aims to make a bibliometric analysis of the studies on breast reduction (BR) between the years 1980 and 2016 and identify important studies through trend topics as well as active authors, countries, universities, scientific journals, and citation and co-citation analyses about BR. Although BR looks like one of the cosmetic surgeries performed in order to restore the woman's appearance, in fact it is a reconstructive surgery that eliminates back pain, stance disorder, headache, shoulder pain, back and cervical disk hernia, difficulty in breathing, hollowness caused by bra straps, hygiene problems under breasts (e.g., rash or fungal infections), and limitations in some daily activities. However, the related literature has little information about the publications on this issue. Bibliometric analysis was performed by downloading all the documents published between 1980 and 2016 from Thomson Reuters Web of Science (WoS; Thomson Reuters, New York, NY, USA), using the keywords including "breast reduction", "gigantomastia", "reduction mammaplasty", and "reduction mammoplasty". There was a total of 1427 publications in the WoS database. Of these publications, 869 (60.90%) were research articles. The top three research areas of these publications were surgery with 1178 (82.55%) publications, oncology with 78 (5.47%) publications, and obstetrics gynecology with 67 (4.70%) publications. The top three countries that contributed to the literature most were the USA (515), England (147), and Turkey (83), respectively; the top university that contributed most was Harvard University, and the top two authors who contributed most were Drew PJ and Iwuagwu OC (13; 0.91%). The top-cited publication was "A Simplified Vertical Reduction Mammaplasty: Shortening the Learning Curve" written by Hall-Findlay, EJ in 1999. The journals with top numbers of publications were Plastic and Reconstructive Surgery (483; 33.85%), Annals of Plastic Surgery (164; 11.50%) and Aesthetic Plastic

    The aim of the present paper was to introduce some online-based approaches to evaluate scientific journals and publishers and to differentiate them from the hijacked ones, regardless of their disciplines. With the advent of open-access journals, many hijacked journals and publishers have deceitfully assumed the mantle of authenticity in order to take advantage of researchers and students. Although these hijacked journals and publishers can be identified through checking their advertisement techniques and their websites, these ways do not always result in their identification. There exist certain online-based approaches, such as using Master Journal List provided by Thomson Reuters, and Scopus database, and using the DOI of a paper, to certify the realness of a journal or publisher. It is indispensable that inexperienced students and researchers know these methods so as to identify hijacked journals and publishers with a higher level of probability.

    We investigated the association between a U.S. National Institutes of Health (NIH) R01 applicant’s self-identified race or ethnicity and the probability of receiving an award by using data from the NIH IMPAC II grant database, the Thomson Reuters Web of Science, and other sources. Although proposals with strong priority scores were equally likely to be funded regardless of race, we find that Asians are 4 percentage points and black or African-American applicants are 13 percentage points less likely to receive NIH investigator-initiated research funding compared with whites. After controlling for the applicant’s educational background, country of origin, training, previous research awards, publication record, and employer characteristics, we find that black or African-American applicants remain 10 percentage points less likely than whites to be awarded NIH research funding. Our results suggest some leverage points for policy intervention. PMID:21852498

But, in both scandals, we also find that the Danish news media went to great lengths to investigate the accusations, document......In 2015 two major journalistic scandals hit the Danish news media. One was a plagiarism scandal in which a freelance foreign correspondent was found to have plagiarized parts of the stories she had filed from other international news media. The other scandal involved a sports journalist who...... was found to have invented a large number of the sources that were quoted in his stories and had made up false co-bylines.

    Full Text Available The analysis of news in the financial context has gained a prominent interest in the last years. This is because of the possible predictive power of such content especially in terms of associated sentiment/mood. In this paper, we focus on a specific aspect of financial news analysis: how the covered topics modify according to space and time dimensions. To this purpose, we employ a modified version of topic model LDA, the so-called Structural Topic Model (STM, that takes into account covariates as well. Our aim is to study the possible evolution of topics extracted from two well known news archive—Reuters and Bloomberg—and to investigate a causal effect in the diffusion of the news by means of a Granger causality test. Our results show that both the temporal dynamics and the spatial differentiation matter in the news contagion.

    An overview of the Data Citation Index is provided. Thomson Reuters developed this resource in response to a stated desire among members of the research community for increased attribution of non-traditional scholarly output. Launched in October of 2012 on the Web of science research platform, its aims include linking published research articles to their underlying data sets and tracking the citation of the data, as well as encouraging bibliographic citation of data. Cross-disciplinary search capabilities in the Index enable new possibilities for data discovery and synthesis. Data repositories are evaluated with respect to various selection criteria, with particular attention to their relevance to scientific and scholarly research. Index content reflects current data deposition practices. As data citation standards and practices continue to move toward widespread formalization and adoption, the initiative seeks to address issues of data citation, reuse, and author credit in a developing climate.

Every second, innumerable text data, including all kinds news, reports, messages, reviews, comments, and tweets are generated on the Internet, and these are written not only in English but also in other languages such as Chinese, Japanese, French, etc. By taking advantage of multi-lingual text resources provided by Thomson Reuters News, we developed two estimation algorithms for extracting cross-lingual news pairs from multilingual text resources. In our first method, we propose a novel structure that uses the word information and the machine learning method effectively in this task. Simultaneously, we developed a bidirectional Long Short-Term Memory (LSTM based method to calculate cross-lingual semantic text similarity for long text and short text, respectively. Thus, when an important news article is published, users can read similar news articles that are written in their native language using our method.

    Within research project 'RELA', tests have been made to determine the amount of entering air to be guided from bottom to top and from ceiling to ceiling in order to obtain equal cooling capacity and air quality as well as equal entering air temperature. On the basis of these results, the 'Schmidt-Reuter Ingenieurgesellschaft', Cologne/Germany, has investigated the effects of air flow on the energy consumption for the equal air conditioning of a conventional office building. Since the energy consumption is also influenced by the sort of air treatment, energy transport by air or water, the selected air temperatures and the adaption of the plant to part-load, the calculation has been performed for a larger number of air treatment and control systems customary today. Furthermore, the effects of the type of air flow on plant size, plant rooms and building construction are shown. The author reports on the resulting influences of the type of air flow on energy consumption and cost of operation.

    The Israel Journal of Health Policy Research (IJHPR) was launched in January 2012 and it is now publishing its 100th article. It was accepted into PubMed after only six months of publication and it has now also been accepted by Thomson Reuters for inclusion in the Web of Science as well as the Social Science Citation Index. It is rare for a new journal to reach these milestones at such an early stage in its development.One of the key factors in the journal's acceptance into these prestigious databases has been its unique national/international approach - exploring both what Israel can learn from health systems in other countries and what other countries can learn from Israeli health care. Another key factor has been its ability to attract high quality contributions from virtually all of the Israeli universities and research centers involved in health policy. A third important factor has been the journal's ability to engage leading international scholars as contributors and/or editorial board members.

    Full Text Available Worldwide corporate cash holdings have significantly increased and have become an important tool for managers. This study explores the factors that influence firms’ behavior regarding cash holdings and the signal that financial conservatism is sending to potential investors. Our data consists in annual observations collected through the Reuters Eikon platform. It includes companies listed on the Bucharest Stock Exchange, the investigated period being 2005-2014. The econometric analysis employs multivariate regression for an unbalanced panel data, using the OLS technique. The results show a positive correlation of cash holdings with the value registered by this indicator in the previous period, fact that might be interpreted as an attempting of the companies to maintain a target level of cash. Also, the results showed a non-linear relationship between leverage and cash holdings, while the tangible assets determine a negative correlation. As regards firm size and ownership concentration, the correlations were not statistically validated.

    2009-10-01

    The present study systematically examined the role of attention in maintenance of spatial representations in working memory as proposed by the attention-based rehearsal hypothesis [Awh, E., Jonides, J., & Reuter-Lorenz, P. A. (1998). Rehearsal in spatial working memory. Journal of Experimental Psychology--Human Perception and Performance, 24(3), 780-790]. Three main issues were examined. First, Experiments 1-3 demonstrated that inhibition and not facilitation of visual processing is often observed at the memorized location during the retention interval. This inhibition was caused by keeping a location in memory and not by the exogenous nature of the memory cue. Second, Experiment 4 showed that inhibition of the memorized location does not lead to any significant impairment in memory accuracy. Finally, Experiment 5 connected current results to the previous findings and demonstrated facilitation of processing at the memorized location. Importantly, facilitation of processing did not lead to more accurate memory performance. The present results challenge the functional role of attention in maintenance of spatial working memory representations.

  20. Statistical modelling of citation exchange between statistics journals.

    Varin, Cristiano; Cattelan, Manuela; Firth, David

    2016-01-01

    Rankings of scholarly journals based on citation data are often met with scepticism by the scientific community. Part of the scepticism is due to disparity between the common perception of journals' prestige and their ranking based on citation counts. A more serious concern is the inappropriate use of journal rankings to evaluate the scientific influence of researchers. The paper focuses on analysis of the table of cross-citations among a selection of statistics journals. Data are collected from the Web of Science database published by Thomson Reuters. Our results suggest that modelling the exchange of citations between journals is useful to highlight the most prestigious journals, but also that journal citation data are characterized by considerable heterogeneity, which needs to be properly summarized. Inferential conclusions require care to avoid potential overinterpretation of insignificant differences between journal ratings. Comparison with published ratings of institutions from the UK's research assessment exercise shows strong correlation at aggregate level between assessed research quality and journal citation 'export scores' within the discipline of statistics.

    The main aim of this paper is to defend the view that, in spite of the broad agreement in favor of the MNCS and the percentile rank indicators, there are two other citation indicators with desirable properties that the above indicators do not posses: (i) a member of the family of high-impact indicators introduced in Albarránet al. (2011), and (ii) a new indicator, based in the work of Herrero & Villar (2013), which measures the relative performance of the different research units in terms of a series of tournaments in which each research unit is confronted with all others repeatedly. We compare indicators from the point of view of their discriminatory power, measured by the range and the coefficient of variation. Using a large dataset indexed by Thomson Reuters, we consider 40 countries that have published at least 10,000 articles in all sciences in 1998-2003. There are two main findings. First, the new indicator exhibits a greater discriminatory power than percentile rank indicators. Second, the high-impact indicator exhibits the greatest discriminatory power. (Author)

    Full Text Available Overfitting is an important problem in machine learning. Several algorithms, such as the extreme learning machine (ELM, suffer from this issue when facing high-dimensional sparse data, e.g., in text classification. One common issue is that the extent of overfitting is not well quantified. In this paper, we propose a quantitative measure of overfitting referred to as the rate of overfitting (RO and a novel model, named AdaBELM, to reduce the overfitting. With RO, the overfitting problem can be quantitatively measured and identified. The newly proposed model can achieve high performance on multi-class text classification. To evaluate the generalizability of the new model, we designed experiments based on three datasets, i.e., the 20 Newsgroups, Reuters-21578, and BioMed corpora, which represent balanced, unbalanced, and real application data, respectively. Experiment results demonstrate that AdaBELM can reduce overfitting and outperform classical ELM, decision tree, random forests, and AdaBoost on all three text-classification datasets; for example, it can achieve 62.2% higher accuracy than ELM. Therefore, the proposed model has a good generalizability.

    University scientific research ability is an important indicator to express the strength of universities. In this paper, the evaluation of university scientific research ability is investigated based on the output of sci-tech papers. Four university alliances from North America, UK, Australia, and China, are selected as the case study of the university scientific research evaluation. Data coming from Thomson Reuters InCites are collected to support the evaluation. The work has contributed new framework to the issue of university scientific research ability evaluation. At first, we have established a hierarchical structure to show the factors that impact the evaluation of university scientific research ability. Then, a new MCDM method called D-AHP model is used to implement the evaluation and ranking of different university alliances, in which a data-driven approach is proposed to automatically generate the D numbers preference relations. Next, a sensitivity analysis has been given to show the impact of weights of factors and sub-factors on the evaluation result. At last, the results obtained by using different methods are compared and discussed to verify the effectiveness and reasonability of this study, and some suggestions are given to promote China's scientific research ability.

    Full Text Available This study examines contributing factors to the differential forecasting abilities of sell-side analysts and the relation between the sentiments of these analysts and their media exposure. In particular, I investigate whether the level of optimism expressed in sell-side analysts’ reports of fifteen constituents of primarily the S&P 500 Oil and Gas Industry1, enhance the media appearance of these analysts. Using a number of variables estimated from the I/B/E/S Detail history database, 15,455 analyst reports collected from Thompson Reuters Investext and analyst media appearances obtained from Dow Jones Factiva from 1999 to 2014, I run a multiple linear regression to determine the effect of independent variables on dependent variables.  I find that an analyst’s forecast accuracy (as measured by the errors inherent in his forecasts is negatively associated with the analyst’s level of media exposure, experience, brokerage size, the number of times he revises his forecasts in a year and the number of companies followed by the analyst, and positively associated with the analyst’s level of optimism expressed in his reports, forecast horizon and the size of the company he follows.

    The growing prevalence of childhood obesity has become a serious health problem over the past decades. As the immune system is greatly affected by excess weight, in this review of reviews, we discuss the findings of review articles about the relationship between childhood/maternal obesity and children's immune system. We searched English-language articles in PubMed, Scopus, ISI Thomson Reuters, and Google Scholar databases. All relevant reviews, either systematic or narrative, were retrieved. Then their quality was assessed by using the Assessment of Multiple Systematic Reviews and International Narrative Systematic Assessment tools, respectively. In the final step, 26 reviews were included. Our review suggests that childhood obesity is associated with extensive changes in the serum levels of inflammatory and anti-inflammatory cytokines and proteins, as well as the number of immune cells and their behavior. Therefore, it might cause or exacerbate diseases such as asthma, allergy, atopic dermatitis (AD), and obstructive sleep apnea syndrome. Moreover, childhood obesity may reduce the immune system responsiveness to vaccines and microorganisms. Furthermore, studies suggest that maternal obesity increases the risk of asthma in offspring. Future studies are needed to determine different associations of childhood obesity with allergy, atophic dermatitis, and autoimmune diseases.

    2018-06-01

    Academic advancement in dermatopathology requires evidence of scientific production. The H-index is a useful bibliometric for measuring scientific production because it weights both volume and impact of an individual's scholastic production. The H-index distribution among academic dermatopathologists is unknown. In this cross-sectional study of 299 dermatopathologists with academic appointments in North America, H-index, publication counts, and citation counts were retrieved from Thomas Reuters Web of Science. Analytic statistics were performed to identify best predictors of academic rank and cutoff points between academic ranks. The H-index was a superior predictor of overall academic rank than publication or citation counts. The median H-index for assistant, associate, and full professors was 4, 6, and 11, respectively. H-index cutoff scores of 8 and 10 favored associate and full professor rank, respectively. These data provide benchmarks for dermatopathologists to gauge their scientific productivity against that of their peers. Although advancement decisions will depend on a careful examination of the scope and impact of a candidate's work, assistant professors of dermatopathology with H-index scores of >7 and associate professors of dermatopathology with H-index scores of >9 may wish to consider application for promotion.

  14. Progress on CMS detector lowering

    2006-01-01

    It was an amazing engineering challenge - the lowering of the first hugeendcap disc (YE+3) of the CMS detector slowly and carefully 100 metres underground. The spectacular descent took place on 30 November and was documented by a film crew from Reuters news group. The uniquely shaped slice is 16 m high, about 50 cm thick, and weighs 400 tonnes. It is one of 15 sections that make up the complete CMS detector. The solid steel structure of the disc forms part of the magnet return yoke and is equipped on both sides with muon chambers. A special gantry crane lowered the element, with just 20 cm of leeway between the edges of the detector and the walls of the shaft! On 12 December, a further section of the detector (YE+2) containing the cathode strip chamber made the 10-hour journey underground. This piece is 16 m high and weighs 880 tonnes. There are now four sections of the detector in the experimental cavern, with a further 11 to follow. The endcap disc YE+3 (seen in the foreground) begins its journey down the ...

  15. Discrete Lognormal Model as an Unbiased Quantitative Measure of Scientific Performance Based on Empirical Citation Data

    Assessing the career performance of scientists has become essential to modern science. Bibliometric indicators, like the h-index are becoming more and more decisive in evaluating grants and approving publication of articles. However, many of the more used indicators can be manipulated or falsified by publishing with very prolific researchers or self-citing papers with a certain number of citations, for instance. Accounting for these factors is possible but it introduces unwanted complexity that drives us further from the purpose of the indicator: to represent in a clear way the prestige and importance of a given scientist. Here we try to overcome this challenge. We used Thompson Reuter's Web of Science database and analyzed all the papers published until 2000 by ~1500 researchers in the top 30 departments of seven scientific fields. We find that over 97% of them have a citation distribution that is consistent with a discrete lognormal model. This suggests that our model can be used to accurately predict the performance of a researcher. Furthermore, this predictor does not depend on the individual number of publications and is not easily ``gamed'' on. The authors acknowledge support from FCT Portugal, and NSF grants

    GE-Reuter-Stokes (GERS) has developed a new line of neutron proportional counters, the B10Plus+* proportional counter. The detector design is intended to serve as a cost-effective alternative to traditional {sup 3}He proportional counters in a variety of applications. The detector is a hybrid design 10B-lined tube optimized with the addition of a small quantity of 3He gas to improve the detector performance and efficiency. As a demonstration of the B10Plus+* detector, GERS has constructed a Uranium Neutron Collar (UNCL) system consisting of B-10Plus+* proportional counters. GERS has designed and built a demonstration UNCL system intended to match the performance of a Type-I UNCL design in Pressurized Water Reactor (PWR) geometry operating in thermal mode. GERS offered their system on loan to the International Atomic Energy Agency (IAEA) Safeguards Division of Technical and Scientific Services for an assessment of the detector technology and the demonstration system. We have characterized the demonstration UNCL system and compared its performance with a traditional Type-I UNCL design in regular use by the IAEA. This paper summarizes our findings and observations during the characterization and testing activity. (authors)

  17. Fair ranking of researchers and research teams.

    Vavryčuk, Václav

    2018-01-01

    The main drawback of ranking of researchers by the number of papers, citations or by the Hirsch index is ignoring the problem of distributing authorship among authors in multi-author publications. So far, the single-author or multi-author publications contribute to the publication record of a researcher equally. This full counting scheme is apparently unfair and causes unjust disproportions, in particular, if ranked researchers have distinctly different collaboration profiles. These disproportions are removed by less common fractional or authorship-weighted counting schemes, which can distribute the authorship credit more properly and suppress a tendency to unjustified inflation of co-authors. The urgent need of widely adopting a fair ranking scheme in practise is exemplified by analysing citation profiles of several highly-cited astronomers and astrophysicists. While the full counting scheme often leads to completely incorrect and misleading ranking, the fractional or authorship-weighted schemes are more accurate and applicable to ranking of researchers as well as research teams. In addition, they suppress differences in ranking among scientific disciplines. These more appropriate schemes should urgently be adopted by scientific publication databases as the Web of Science (Thomson Reuters) or the Scopus (Elsevier).

    2018-04-01

    This article provides a brief introduction to the Health Insurance Portability and Accountability Act of 1996 (HIPAA) Privacy Rule's minimum necessary standard, which applies to sharing of genomic data, particularly clinical data, following 2013 Privacy Rule revisions. This research used the Thomson Reuters Westlaw database and law library resources in its legal analysis of the HIPAA privacy tiers and the impact of the minimum necessary standard on genomic data sharing. We considered relevant example cases of genomic data-sharing needs. In a climate of stepped-up HIPAA enforcement, this standard is of concern to laboratories that generate, use, and share genomic information. How data-sharing activities are characterized-whether for research, public health, or clinical interpretation and medical practice support-affects how the minimum necessary standard applies and its overall impact on data access and use. There is no clear regulatory guidance on how to apply HIPAA's minimum necessary standard when considering the sharing of information in the data-rich environment of genomic testing. Laboratories that perform genomic testing should engage with policy makers to foster sound, well-informed policies and appropriate characterization of data-sharing activities to minimize adverse impacts on day-to-day workflows.

    suicide is a problem with world impact and the leading cause of premature deaths. The study of its distribution over time can bring a changed understanding of parameters attributed to, and the prevention of, suicide. to identify the temporal pattern of suicide by systematic review. Pubmed (Medline), LILACS, Virtual Health Library (VHL), Science Direct and Scopus (Elsevier), Web of Science (Thomson Reuters) and PsyNET (APA) were searched, using suicide-related descriptors and terms, for observational epidemiological studies of the temporal distribution of suicide. The review protocol was registered in PROSPERO (CRD42016038470). The lack of uniformity in reporting or standardisation of methodology in the studies selected, hindered comparison of populations with similar socioeconomic and cultural profiles, considerably limiting the scope of the results of this review. forty-five studies from 26 different countries were included in this review. Clear seasonal patterns were observed by day of the week, month, season and age-period-cohort effects. Few studies studied by trend, time of day or day of the month. the review findings provide further evidence of substantial temporal patterns influenced by geographic, climatic and social conditions.

    2003-05-01

    Full Text Available Many studies have attempted to evaluate the importance of airborne fungi in the development of invasive fungal infection, especially for immunocompromised hosts. Several kinds of instruments are available to quantitate fungal propagule levels in air. We compared the performance of the most frequently used air sampler, the Andersen sampler with six stages, with a portable one, the Reuter centrifugal sampler (RCS. A total of 84 samples were analyzed, 42 with each sampler. Twenty-eight different fungal genera were identified in samples analyzed with the Andersen instrument. In samples obtained with the RCS only seven different fungal genera were identified. The three most frequently isolated genera in samples analyzed with both devices were Penicillium, Aspergillus and Cladophialophora. In areas supplied with a high efficiency particulate air filter, fungal spore levels were usually lower when compared to areas without these filters. There was a significant correlation between total fungal propagule measurements taken with both devices on each sampling occasion (Pearson coefficient = 0.50. However, the Andersen device recovered a broader spectrum of fungi. We conclude that the RCS can be used for quantitative estimates of airborne microbiological concentrations. For qualitative studies, however, this device cannot be recommended.

    Bibliometric review of the literature. This bibliometric analysis aims to give an overview of the most influential academic literature written on spinal tuberculosis. All databases included in the Thomson Reuters Web of Knowledge were searched for the most influential publications in spinal tuberculosis. The most cited articles published between 1950 and 2015, with the main focus on orthopedic surgery, were identified using a multistep approach, and a total of 100 articles were included. The publications were then analyzed in this bibliometric analysis. The number of citations ranged from 243 to 36, with an average of 77.11. The articles were published in 34 different journals, and the studies were conducted in 20 different countries. The top 3 countries, India, the United States, and China, published a total of 51% (n = 51) of all articles. Low-burden countries produced 60% (n = 60) of all articles in our list. African centers produced only 4% (n = 4) of all included articles. Indian and Chinese researchers dominate evidence in spinal tuberculosis. Other areas with high disease burden, such as Africa, do not feature. Most publications are retrospective studies with a low level of evidence.

    This paper has briefly analyzed the publication status of Chinese stomatology papers in 2009 with statistics from Journal Citation Reports provided by Thomson Scientific. Only those papers with the first author coming from the mainland of China were included for calculations. We have found a significant increase in the number of SCIE-indexed papers, most of which were published by six dental institutions in China. Among all Chinese medical institutions, West China School of Stomatology Sichuan University is the first dental institution to enter the top-20 list with the most publications, and it also ranks the 9th in the number of outstanding articles. West China School of Stomatology Sichuan University and the Forth Military Medical University are the only two dental institutions in China which have published SCIE-indexed papers over a hundred. The former has published the most SCIE-indexed stomatology papers, while the latter has the highest average impact factor. As the laboratories and funds in China have close connections with various dental hospitals, the pratice of translational medicine in dentistry is fast and fluent.

    2012-01-01

    The Korean journal published in English, Nuclear Engineering and Technology (here under NET) has been enlisted in the global citation database SCI E(Science Citation Index Expanded) of Thomson Reuters (past ISI), beginning with NET vol.39 No.1 (Feb. 2007). As of July 2009, the citation index of NET as reported by JCR (Journal Citation Report) based on the cumulative data from ISI (Institute for Scientific Information) reached to 0.991. This index ranks on 12 th among the 33 journals in the area of nuclear science and technology in the science and technology covered by JCR, meaning fairly high impact factor. The following year 2010, however, witnessed the JCR figure dropping down to 0.465. The reason behind such drastic fall would be the decreased citation and in a lesser extent self-citation in 2010, in comparison with 2009, despite the increased number of paper publication. This study attempts to give an analysis as of the end of 2011 on the NET citation frequency in SCI Source Journal and the citation frequency by KAERI authors, together with the nationalities of NET authors and SCI journals that refer to NET most. Based on the analysis, the paper suggests some ways to promoting the position of NET as a journal in the international nuclear sector

    Full Text Available Alcohol use disorders (AUD exacerbate neurocognitive dysfunction in Human Immunodeficiency Virus (HIV+ patients. We have shown that chronic binge alcohol (CBA administration (13–14 g EtOH/kg/wk prior to and during simian immunodeficiency virus (SIV infection in rhesus macaques unmasks learning deficits in operant learning and memory tasks. The underlying mechanisms of neurocognitive alterations due to alcohol and SIV are not known. This exploratory study examined the CBA-induced differential expression of hippocampal genes in SIV-infected (CBA/SIV+; n = 2 macaques in contrast to those of sucrose administered, SIV-infected (SUC/SIV+; n = 2 macaques. Transcriptomes of hippocampal samples dissected from brains obtained at necropsy (16 months post-SIV inoculation were analyzed to determine differentially expressed genes. MetaCore from Thomson Reuters revealed enrichment of genes involved in inflammation, immune responses, and neurodevelopment. Functional relevance of these alterations was examined in vitro by exposing murine neural progenitor cells (NPCs to ethanol (EtOH and HIV trans-activator of transcription (Tat protein. EtOH impaired NPC differentiation as indicated by decreased βIII tubulin expression. These findings suggest a role for neuroinflammation and neurogenesis in CBA/SIV neuropathogenesis and warrant further investigation of their potential contribution to CBA-mediated neurobehavioral deficits.

    The Amazon region has been part of climate change debates for decades, yet attention to its social and health dimensions has been limited. This paper assesses literature on the social and health dimensions of climate change in the Amazon. A conceptual framework underscores multiple stresses and exposures created by interactions between climate change and local social-environmental conditions. Using the Thomson-Reuter Web of Science, this study bibliometrically assessed the overall literature on climate change in the Amazon, including Physical Sciences, Social Sciences, Anthropology, Environmental Science/Ecology and Public, Environmental/Occupational Health. From this assessment, a relevant sub-sample was selected and complemented with literature from the Brazilian database SciELO. This sample discusses three dimensions of climate change impacts in the region: livelihood changes, vector-borne diseases and microbial proliferation, and respiratory diseases. This analysis elucidates imbalance and disconnect between ecological, physical and social and health dimensions of climate change and between continental and regional climate analysis, and sub-regional and local levels. Work on the social and health implications of climate change in the Amazon falls significantly behind other research areas, limiting reliable information for analytical models and for Amazonian policy-makers and society at large. Collaborative research is called for.

    Full Text Available In recent times some publishers are intensively exploiting the model of open access publishing. During the last several years, studies have shown that there was a substantial increase in the number of fake publishers and hijacked journals. These cyber criminals make money by stealing the identities of legitimate journals and collecting the article processing charges on the papers that are submitted. This is all accomplished by a well developed framework that includes web development steps, intensive e-mail marketing and victim selections. This review article strives to recommend that the Beall's list of predatory publishers and journals should be consulted every time when an author plans to submit scientific work to some of the journals that are indexed by Thomson Reuters/Institute for Scientific Information-ISI and covered by the Journal Citation Report. Also, the authors are advised to be 'up to date' with new information regarding this controversial topic by informing themselves through various web-sites and specialized scientific portals. The review paper itself strives to summarize the most recent investigations on predatory and spurious journals/publishers which affect the entire scientific community, thus representing an outbreak with rising trend not only on national and regional level, but on global level as well.

    Full Text Available The efficacy of two different regimens of physiotherapy for epicondylitis was compared. A combination treatment with hydrogalvanic four-cell bath and arm bath with rising temperature, which had showed good effects in treatment of tennis elbow in an earlier observational study (Mucha 1987, was compared with the analgesic interference current treatment often recommended in the literature (Sadil and Sadil 1994, Noteboom et al 1994, Becker and Reuter 1982. For this study, 60 patients with epicondylitis that was resistant to conservative treatment were randomized into two groups for comparison. In group 1, interference currents were administered twice a day for six weeks and group 2 received combination treatment with the hydrogalvanic four-cell bath and rising- temperature arm bath once a day for six weeks. Criteria for inclusion, control and appraisal were laid down prospectively. Several parameters were used, recorded and statistically evaluated as outcome measures.  These were active joint range of movement of the elbow, grip strength, pain provocation with muscle contraction, palpation pain and pain with functional activities.  The results showed a significant superiority of combination treatment over therapy with interference current. It is therefore recommended that hydrogalvanic four-cell bath and arm bath with rising temperature should be carried out before considering surgical treatment for chronic epicondylitis.

  12. PATENT ANALYSIS: A LOOK AT THE INNOVATIVE NATURE OF PLANT-BASED COSMETICS

    Full Text Available The use of plants have become a important trend in cosmetic market, with a crescent number of patent applications. Despite various herbal-based ingredients have been described in scientific literature, most of them are restricted to patent databases. In this work we analyze the innovative use of plants and its derivatives in cosmetic technologies, based on patent analysis. The investigation was conducted using Derwent World Patents Index (Thomson Reuters Scientific, USA from 1995 to 2015. The search was carried out to evaluate the number of patent deposits, the patent depositors profiles, the countries with most patent applications, the International Patent Classification (IPC and the main plant families using in cosmetics. Patent analysis revealed an increase number of applications involving cosmetic containing plants components, with a higher number of deposits related to anti-ageing and whitening skin treatment. Fabaceae, Asteraceae, Rosaceae, Lamiaceae, Poaceae, Rutaceae, Lilliacae and Apiaceae were the key plant families used in cosmetic formulations for skin care treatment. Comparison between scientific and technological data pointed out divergences between patents deposits and aid-based scientific reports. The use of patent analysis in combination with scientific data opens up wider aspects of knowledge and enables a better rationalization of innovative works.

    Full Text Available It has recently been shown that a person, an author particularly, faces the challenges of visualization in the cognitive process. The aim of this study is to consider the forms of thinking process and the changes happened in education process and in scientific activity. It was noted that the challenges connected with information perceiving during the work with the text occur in the process of creating academic papers as well. We conclude that the topical field of visualization covers not only the educative process assuming information transfer from person to person (model “teacher-student”, but the process of scientific activity. Applying the methods of visualization in publication activity is the factor for effective communication in social and cultural space that provides the opportunity for academic society to recognize results. We offer possible ways to promote scientific papers via online resources such as scientific social networks and tools of media corporations. The scientific social network ResearchGate and Thomson Reuters media corporation product as an online tool “Researcher ID” placed at the bibliographic database Web of Science TM Core Collection are used as the examples. We state that information technology allows authors to promote the results of their studies around the world.

    2017-06-01

    The interest in children's eating behaviours and how to change them has been growing in recent years. This review examines the following questions: What strategies have been used to change children's eating behaviours? Have their effects been experimentally demonstrated? And, are the effects transient or enduring? Medline and Cab abstract (Ovid) and Web of Science (Thomson Reuters) were used to identify the experimental studies. A total of 120 experimental studies were identified and they are presented grouped within these 11 topics; parental control, reward, social facilitation, cooking programs, school gardens, sensory education, availability and accessibility, choice architecture and nudging, branding and food packaging, preparation and serving style, and offering a choice. In conclusion, controlling strategies for changing children's eating behaviour in a positive direction appear to be counterproductive. Hands-on approaches such as gardening and cooking programs may encourage greater vegetable consumption and may have a larger effect compared to nutrition education. Providing children with free, accessible fruits and vegetables have been experimentally shown to positively affect long-term eating behaviour. The authors recommend future research to examine how taste and palatability can positively affect children's attitudes and eating behaviour. Copyright © 2017 The Authors. Published by Elsevier Ltd..

    González-Álvarez, Julio; Cervera-Crespo, Teresa

    2017-05-15

    Despite important advances made in recent decades, women are still underrepresented in science (less than 30% of authorships). This study presents a bibliometric analysis of all the Psychology articles published in 2009 included in the Web of Science database (Thomson Reuters) in order to examine the contribution of women in contemporary Psychology, their pattern of research collaboration, the scientific content and the scientific impact from a gender perspective. From a total of 90,067 authorships, gender could be identified in 74,413 (82.6%) of them, being 40,782 (54.8%) male authorships and 33,631 (45.2%) female authorships. These data corresponded to 24,477 (49.9%) individual men and 24,553 (50.1%) women, respectively. Therefore, Psychology presents gender parity in the number of authors, and a gender asymmetry in the number of authorships that it is much lower than in science in general and other specific scientific fields. In relative terms, women tend to be concentrated in the first position of the authorship by-line and much less in the last (senior) position. This double pattern suggests that age probably plays a role in (partly) explaining the slight gender disparity of authorships. © 2017 International Union of Psychological Science.

    Full Text Available Translation has always undergone the impact of various metalinguistic factors which impose their impact during the process of translation and rendering its final linguistic product. News stories or better to say political discourses are among those linguistic materials that more than other textual materials undergo the impact of factors such as ideology. Not being aware of such discursive practices leads the so-called translator to suffice to linguistic substitutions without observing imbedded intentions. For the purpose of this study through a qualitative type of research and based on critical discourse analysis (CDA approach for textual analysis and following Tymoczko’s concept of power (2002 in translation this study aimed to scrutinize the impact of power on Persian translations of different pieces of news stories in English in 2012. The corpus consists of some pieces of English news stories in worldwide news agencies (namely, Reuters, Washington Post, New York Post, and Forbes about Iran’s nuclear program. Results of the study showed that ideology is the very important stimulus which can control and direct the purpose of the news stories being translated from English to Persian and reveal its impact in a desired way as news stories for target audience.

    ABSTRACTThis study analyzed and assessed publication trends in articles on "disaster medicine," using scientometric analysis. Data were obtained from the Web of Science Core Collection (WoSCC) of Thomson Reuters on March 27, 2017. A total of 564 publications on disaster medicine were identified. There was a mild increase in the number of articles on disaster medicine from 2008 (n=55) to 2016 (n=83). Disaster Medicine and Public Health Preparedness published the most articles, the majority of articles were published in the United States, and the leading institute was Tohoku University. F. Della Corte, M. D. Christian, and P. L. Ingrassia were the top authors on the topic, and the field of public health generated the most publications. Terms analysis indicated that emergency medicine, public health, disaster preparedness, natural disasters, medicine, and management were the research hotspots, whereas Hurricane Katrina, mechanical ventilation, occupational medicine, intensive care, and European journals represented the frontiers of disaster medicine research. Overall, our analysis revealed that disaster medicine studies are closely related to other medical fields and provides researchers and policy-makers in this area with new insight into the hotspots and dynamic directions.

    Benjamin Raimbault

    Full Text Available In this paper, we apply an original scientometric analyses to a corpus comprising synthetic biology (SynBio publications in Thomson Reuters Web of Science to characterize the emergence of this new scientific field. Three results were drawn from this empirical investigation. First, despite the exponential growth of publications, the study of population level statistics (newcomers proportion, collaboration network structure shows that SynBio has entered a stabilization process since 2010. Second, the mapping of textual and citational networks shows that SynBio is characterized by high heterogeneity and four different approaches: the central approach, where biobrick engineering is the most widespread; genome engineering; protocell creation; and metabolic engineering. We suggest that synthetic biology acts as an umbrella term allowing for the mobilization of resources, and also serves to relate scientific content and promises of applications. Third, we observed a strong intertwinement between epistemic and socio-economic dynamics. Measuring scientific production and impact and using structural analysis data, we identified a core set of mostly American scientists. Biographical analysis shows that these central and influential scientists act as "boundary spanners," meaning that their importance to the field lies not only in their academic contributions, but also in their capacity to interact with other social spaces that are outside the academic sphere.

    Full Text Available Traditionally, the economic international journalism has had in the Anglo-Saxon groups Dow Jones (USA and Pearson (Great Britain, publishers of The Wall Street and Financial Times respectively, his big world models. Nevertheless, the new century has brought enormous convulsions to the sector, to the newspapaers of elite and big agencies specialized in economic information as Reuters, Thomson or Bloomberg. To the battle in Internet, there add the expansion of the informative economic power and the changes of mentality of the companies and of the audiences. All this has derived in a fierce war led by the big leaders who, with more than one century of tradition someones, have been object of sales or mergers, financial indispensable operations to be able to adapt to the new times. The aim of this article is to analyze the path of the great economic journalism, with special dedication to two fronts: one, to know how these neswspapers of elite are positioned in the network; other one, the dilemma between continuing being a journalism of quality, rigorous, cosmopolitan and expensive of supporting, or to change towards an ideological, gruesome journalism or amarillista that, since in other specialities, also has spread between the financial journalism

    Full Text Available Bioprinting as a tissue engineering tool is one of the most promising technologies for overcoming organ shortage. However, the spread of populist articles among on this technology could potentially lead public opinion to idealize its readiness. This bibliometric study aimed to trace the evolution of bioprinting literature over the past decade (i.e., 2000 to 2015 using the SCI-expanded database of Web of Science® (WoS, Thomson Reuters. The articles were analyzed by combining various bibliometric tools, such as science mapping and topic analysis, and a Technology Readiness Scale was adapted to assess the evolution of this emerging field. The number of analyzed publications was low (231, but the literature grew exceptionally fast. The “Engineering, Biomedical” was still the most represented WoS category. Some of the recent fronts were “hydrogels” and “stem cells”, while “in vitro” remained one of the most used keywords. The number of countries and journals involved in bioprinting literature grew substantially in one decade, also supporting the idea of an increasing community. Neither the United States’ leadership in bioprinting productivity nor the role of universities in publications were challenged. “Biofabrication” and “Biomaterials” journals were still the leaders of the bioprinting field. Bioprinting is a young but promising technology.

    Charting significant growth in science production over the 20th century in four European Union member states, this neo-institutional analysis describes the development and current state of universities and research institutes that bolster Europe's position as a key region in global science. On-going internationalization and Europeanization of higher education and science has been accompanied by increasing competition as well as collaboration. Despite the policy goals to foster innovation and further expand research capacity, in cross-national and historical comparison neither the level of R&D investments nor country size accounts completely for the differential growth of scientific productivity. Based on a comprehensive historical database from 1900 to 2010, this analysis uncovers both stable and dynamic patterns of production and productivity in Germany, France, Belgium, and Luxembourg. Measured in peer-reviewed research articles collected in Thomson Reuters' Science Citation Index Expanded, which includes journals in the fields of Science, Technology, Engineering, Mathematics, and Health, we show the varying contributions of different organizational forms, especially research universities and research institutes. Comparing the institutionalization pathways that created the conditions necessary for continuous and strong growth in scientific productivity in the European center of global science emphasizes that the research university is the key organizational form across countries.

    Modern information society is facing the challenge of handling massive volume of online documents, news, intelligence reports, and so on. How to use the information accurately and in a timely manner becomes a major concern in many areas. While the general information may also include images and voice, we focus on the categorization of text data in this paper. We provide a brief overview of the information processing flow for text categorization, and discuss two supervised learning algorithms, viz., support vector machines (SVM) and partial least squares (PLS), which have been successfully applied in other domains, e.g., fault diagnosis [9]. While SVM has been well explored for binary classification and was reported as an efficient algorithm for text categorization, PLS has not yet been applied to text categorization. Our experiments are conducted on three data sets: Reuter's- 21578 dataset about corporate mergers and data acquisitions (ACQ), WebKB and the 20-Newsgroups. Results show that the performance of PLS is comparable to SVM in text categorization. A major drawback of SVM for multi-class categorization is that it requires a voting scheme based on the results of pair-wise classification. PLS does not have this drawback and could be a better candidate for multi-class text categorization.

    Media-based event data-i.e., data comprised from reporting by media outlets-are widely used in political science research. However, events of interest (e.g., strikes, protests, conflict) are often underreported by these primary and secondary sources, producing incomplete data that risks inconsistency and bias in subsequent analysis. While general strategies exist to help ameliorate this bias, these methods do not make full use of the information often available to researchers. Specifically, much of the event data used in the social sciences is drawn from multiple, overlapping news sources (e.g., Agence France-Presse, Reuters). Therefore, we propose a novel maximum likelihood estimator that corrects for misclassification in data arising from multiple sources. In the most general formulation of our estimator, researchers can specify separate sets of predictors for the true-event model and each of the misclassification models characterizing whether a source fails to report on an event. As such, researchers are able to accurately test theories on both the causes of and reporting on an event of interest. Simulations evidence that our technique regularly out performs current strategies that either neglect misclassification, the unique features of the data-generating process, or both. We also illustrate the utility of this method with a model of repression using the Social Conflict in Africa Database.

    Bibliometrics play an increasingly critical role in the assessment of faculty for promotion and merit increases. Bibliometrics is the statistical analysis of publications, aimed at evaluating their impact. The objective of this study is to describe h-index and citation benchmarks in academic psychiatry. Faculty lists were acquired from online resources for all academic departments of psychiatry listed as having residency training programs in Canada (as of June 2016). Potential authors were then searched on Web of Science (Thomson Reuters) for their corresponding h-index and total number of citations. The sample included 1683 faculty members in academic psychiatry departments. Restricted to those with a rank of assistant, associate, or full professor resulted in 1601 faculty members (assistant = 911, associate = 387, full = 303). h-index and total citations differed significantly by academic rank. Both were highest in the full professor rank, followed by associate, then assistant. The range in each, however, was large. This study provides the initial benchmarks for the h-index and total citations in academic psychiatry. Regardless of any controversies or criticisms of bibliometrics, they are increasingly influencing promotion, merit increases, and grant support. As such, benchmarking by specialties is needed in order to provide needed context.

  7. Does Intellectual Capital Disclosure Matter for Audit Risk? Evidence from the UK and Italy

    Full Text Available Disclosure theory argues that better information quality reduces audit risk, by decreasing information asymmetry in the market and consequently, information risk for firms. Extant literature on voluntary disclosure analyzes the relationships between Corporate Social Responsibility (CSR and audit risk, finding that auditors charge lower fees and issue less going concern opinions to firms with good CSR performance. In this study, we test the relationship between intellectual capital disclosure (ICD and audit risk and we assess the effect of ICD and audit risk on audit fees. To do so, we use data from the ESG Asset4 database (Thomson Reuters Datastream on 166 UK and 27 Italian listed firms that issue stand-alone social and intellectual capital statements. The audit risk is measured from both a qualitative and a quantitative perspective. Panel data analysis on 2004–2011 years has been used to test our research hypotheses. Empirical findings from a sample of UK and Italian listed companies show that auditors estimate a lower qualitative risk, albeit a higher quantitative one, for those companies reporting higher ICD scores, compared to those ones with lower disclosure scores on the intellectual capital. Furthermore, we find that reputation risk contributes to the relationship between ICD and audit risk.

So with this age, archeological research institute is required to make a real contribution to the nation based on the scientific publication. Scientific journal for decades using the paradigm of the printed journal, but now with many rules imposed by LIPI and Dikti are faced with a new paradigm, that is management of ejournal. The enactment of ejournal regulations positively impact on the dissemination of Indonesian scientific journals globally. Since 2016 counted ten media ejurnal developed by the Puslit Arkenas and Balai Arkeologi have been active online. The condition of Indonesian archaeology ejournals so far have not yet reached the ideal expectations as a level of national research institute, but based on the research result in this study shows that the Indonesian archaeology ejournals have a prospect to become International journal. The result of the study also reveals that there are still some obstacles either in technical or non technical. Puslit Arkenas and Balai Arkeologi are expected to run along to developing strategy towards national accreditation in the near and road to international journal in the long term. The highest contribution of national research institute to the nation is having the research published in scientific journals recognized by one of the two International indexer institutions of high repute, the Thomson Reuters / Web of Sciene and Scopus.   Lembaga riset arkeologi Indonesia telah berusia lebih dari satu abad, sejak didirikannya Oudheidkundige Dienst oleh Pemerintah Kolonial di tahun 1913 hingga saat ini menjadi Pusat Penelitian Arkeologi Nasional dengan membawahi sepuluh Balai Arkeologi.

    The impact factor (IF), as the most important criterion for journal's quality measurement, is affected by the self-citation and number of publications in each journal. To find out the relationship between the number of publications and self-citations in a journal, and their correlations with IF. Self-citations and impact factors of nine top gastroenterology and hepatology journals were assessed during the seven recent years (2005-2011) through Journal Citation Reports (JCR, ISI Thomson Reuters). Although impact factors of all journals increased during the study, five out of nine journals increased the number of publications from 2005 to 2011. There was an increase in self-citation only in the journal of HEPATOLOGY (499 in 2005 vs. 707 in 2011). Impact factors of journals (6.5 ± 3.5) were positively correlated with total number of publications (248.6 ± 91.7) (R: 0.688, P citation rate (238.73 ± 195.317) was highly correlated with total number of publications in each journal (248.6 ± 91.7) (R: 0.861, P citation (6.08 ± 3.3) had a correlation (R: 0.672, P citation have definite effects on IF of a journal and because IF is the most prominent criterion for journal's quality measurement, it would be a good idea to consider factors affecting on IF such as self-citation.

    False working memories readily emerge using a visual item-recognition variant of the converging associates task. Two experiments, manipulating study and test modality, extended prior working memory results by demonstrating a reliable false recognition effect (more false alarms to associatively related lures than to unrelated lures) within seconds of encoding in either the visual or auditory modality. However, false memories were nearly twice as frequent when study lists were seen than when they were heard, regardless of test modality, although study-test modality mismatch was generally disadvantageous (consistent with encoding specificity). A final experiment that varied study-test modality using a hybrid short- and long-term memory test (Flegal, Atkins & Reuter-Lorenz, 2010) replicated the auditory advantage in the short term but revealed a reversal in the long term: The false memory effect was greater in the auditory study-test condition than in the visual study-test condition. Thus, the same encoding conditions gave rise to an opposite modality advantage depending on whether recognition was tested under short-term or long-term memory conditions. Although demonstrating continuity in associative processing across delay, the results indicate that delay condition affects the availability of modality-dependent features of the memory trace and, thus, distinctiveness, leading to dissociable patterns of short- and long-term memory performance.

    The authors propose a novel bibilometric index, the reverberation index (r-index), as a comparative assessment tool for use in determining differential reverberation between scientific fields for a given scientific entity. Conversely, this may allow comparison of 2 similar scientific entities within a single scientific field. This index is calculated using a relatively simple 3-step process. Briefly, Thompson Reuters' Web of Science is used to produce a citation report for a unique search parameter (this may be an author, journal article, or topical key word). From this citation report, a list of citing journals is retrieved from which a weighted ratio of citation patterns across journals can be calculated. This r-index is then used to compare the reverberation of the original search parameter across different fields of study or wherever a comparison is required. The advantage of this novel tool is its ability to transcend a specific component of the scientific process. This affords application to a diverse range of entities, including an author, a journal article, or a topical key word, for effective comparison of that entity's reverberation within a scientific arena. The authors introduce the context for and applications of the r-index, emphasizing neurosurgical topics and journals for illustration purposes. It should be kept in mind, however, that the r-index is readily applicable across all fields of study.

    Full Text Available This study aimed to investigate whether the world wide agreed models of valuation of derivates may be properly applied to the Romanian capital market, obtaining reliable results for decision makers. The most common valuation models take into account market data such as, interest and exchange rates, volatilities and the price of the underlying instrument. The procedures for valuation must clearly define the nature of the market data to be taken into consideration (for example the zero-coupon curve for the valuation of swaps and the independent reference base to be used (Reuters at a given time, bid/offer or mid price, broker. In order to be able to obtain the results, I based my study on a self-developed software which can calculate the price and characteristics for different types of derivatives securities once the primary data are filled in. I compared the results obatined usig the valuation models with the actual prices on the Romanian capital market. I expected that the results obtained to be more accurate as the parameters used in the calculation models properly reflect market data as at that date being as widely as possible.. These assumptions were only supported for certain value orientations. In conclusion, explanations for these results are given and limitations for this study are discussed. Also, suggestions for future research are presented in the final part of the article.

  14. Theft of Virtual Property — Towards Security Requirements for Virtual Worlds

    Beyer, Anja

    The article is focused to introduce the topic of information technology security for Virtual Worlds to a security experts’ audience. Virtual Worlds are Web 2.0 applications where the users cruise through the world with their individually shaped avatars to find either amusement, challenges or the next best business deal. People do invest a lot of time but beyond they invest in buying virtual assets like fantasy witcheries, wepaons, armour, houses, clothes,...etc with the power of real world money. Although it is called “virtual” (which is often put on the same level as “not existent”) there is a real value behind it. In November 2007 dutch police arrested a seventeen years old teenager who was suspicted to have stolen virtual items in a Virtual World called Habbo Hotel [Reuters07]. In order to successfully provide security mechanisms into Virtual Worlds it is necessarry to fully understand the domain for which the security mechansims are defined. As Virtual Worlds must be clasified into the domain of Social Software the article starts with an overview of how to understand Web 2.0 and gives a short introduction to Virtual Worlds. The article then provides a consideration of assets of Virtual Worlds participants, describes how these assets can be threatened and gives an overview of appopriate security requirements and completes with an outlook of possible countermeasures.

    This study aimed to investigate the degree of research outcome in medical science subjects in Pakistan during the period 1996-2012. In this study, the research papers published in various global science journals during the period 1996-2012 were accessed. We recorded the total number of research documents having an affiliation with a Pakistan. The main source for information was Institute of Scientific Information (ISI) Web of Science, Thomson Reuters and SCI-mago/Scopus. In global science, Pakistan contributed 58133 research papers in all science and social sciences both in ISI and non ISI indexed journals. However, in medical sciences the total number of research papers from Pakistan are 25604, citable documents 23874, citations 128061, mean citations per documents 6.45 and mean Hirsch index is 35.33. In Pakistan, the upward trend of articles published in global medical science was from the period 1996-2008. However, from 2008 the trend is markedly declined. Pakistan significantly improved its international ranking positions in research during the period 2000-2008. However, the upward trend of research papers published in global medical science could not be retained and from the year 2008 the trend started declining. This trend of research papers further declined in year 2012 compared to year 2011. It is suggested that, Pakistan must take strategic steps to enhance the research culture and increase the research and development expenditure in the country.

    Full Text Available Achyranthes aspera (family Amaranthaceae is known for its anticancer properties. We have systematically validated the in vitro and in vivo anticancer properties of this plant. However, we do not know its mode of action. Global gene expression analyses may help decipher its mode of action. In the absence of identified active molecules, we believe this is the best approach to discover the mode of action of natural products with known medicinal properties. We exposed human pancreatic cancer cell line MiaPaCa-2 (CRL-1420 to 34 μg/mL of LE for 24, 48, and 72 hours. Gene expression analyses were performed using whole human genome microarrays (Agilent Technologies, USA. In our analyses, 82 (54/28 genes passed the quality control parameter, set at FDR ≤ 0.01 and FC of ≥±2. LE predominantly affected pathways of immune response, metabolism, development, gene expression regulation, cell adhesion, cystic fibrosis transmembrane conductance regulation (CFTR, and chemotaxis (MetaCore tool (Thomson Reuters, NY. Disease biomarker enrichment analysis identified LE regulated genes involved in Vasculitis—inflammation of blood vessels. Arthritis and pancreatitis are two of many etiologies for vasculitis. The outcome of disease network analysis supports the medicinal use of A. aspera, viz, to stop bleeding, as a cure for pancreatic cancer, as an antiarthritic medication, and so forth.

    Helichrysum picardii Boiss. & Reuter is a Mediterranean vegetal species from the Asteraceae family. From the methanolic extract of the aerial flowering parts of this plant, a fraction of two pentacyclic triterpenes has been isolated. Gas chromatography revealed that the triterpene isomers ursolic and oleanolic acids comprised 69% and 29% respectively of the composition of this fraction. The triterpene isomeric fraction was tested in two phagocyte cell systems. It inhibited compound 48/80-induced histamine release from rat peritoneal mast cells in an approximately percentage of 45% at 100 microM and myeloperoxidase secretion from A23187-ionophore-stimulated rat peritoneal leukocytes in a significant manner at doses of 50 and 100 miroM. Furthermore, the triterpene isomers very significantly and dose-dependently inhibited generation of the cyclo-oxygenase metabolite prostaglandin E2 (41% inhibition at 50 miroM) and the 5-lipoxygenase metabolite leukotriene B4 (79% inhibition at 50 microM) from activated rat leukocytes. This anti-eicosanoid activity of the triterpene fraction was more potent than that produced by the pure triterpene oleanolic acid used for comparision, indicating a stronger action of the ursolic acid, the major compound of the isolated triterpene fraction. From these data, it can be suggested that the triterpene isomers oleanolic and ursolic acids present in the medicinal plant Helichrysum picardii contribute to the anti-inflammatory profile of this vegetal species.

  18. Credit risk in the pool-implications for private capital investments in Brazilian power generation

    Rocha, Katia; Alcaraz Garcia, Francisco A.

    2006-01-01

    The new Brazilian Electric Sector Regulation of 2004 introduced two negotiation markets: the regulated pool and the free market. Competition in the pool is enforced via energy auctions, where the winning generator has to sign long-term power purchase agreements simultaneously with all distributors at the bidding-price. To estimate the appropriate credit risk spread of the pool, we implement a clustering methodology to rank and rate the distributors. The results show an average spread between 5.75% and 8.5%, which corresponds to a credit rating of B- according to the spreads available in Reuters 2004. This estimation is at least 208 basis points higher than the credit rating Ba1/BB+ assigned to the distributors by the National Electric Energy Agency (ANEEL) in the periodic tariff revisions. Distributors with higher risk/spread are located in the South-Southeast, compared to the low risk/spread ones concentrated in the North-Northeast. We estimate the opportunity cost of capital in real terms in the range of 13-16% to account for the credit risk of the pool. Essential to determine the bidding price at the auctions, this estimation is higher than the 11.26% opportunity cost estimated by ANEEL. The pool's credit risk has to be taken into consideration, especially for compensating new private capital investments in Brazilian power generation

    Social media and electronic news media activity are an important source of information for the general public. Yet, there is a dearth of research exploring the use of Twitter and electronic news outlets during significant worldly events such as the recent Ebola Virus scare. The purpose of this article is to investigate the use of Twitter and electronic news media outlets in communicating Ebola Virus information. A cross-sectional survey of Twitter data and Google News Trend data from 30 September till 29 October, 2014 was conducted. Between 30 September and 29 October, there were approximately 26 million tweets (25,925,152) that contained the word Ebola. The highest number of correlated activity for Twitter and electronic news outlets occurred on 16 October 2014. Other important peaks in Twitter data occurred on 1 October, 6 October, 8 October, and 12 October, 2014. The main influencers of the Twitter feeds were news media outlets. The study reveals a relationship between electronic news media publishing and Twitter activity around significant events such as Ebola. Healthcare organizations should take advantage of the relationship between electronic news media and trending events on social media sites such as Twitter and should work on developing social media campaigns in co-operation with leading electronic news media outlets (e.g. CNN, Yahoo, Reuters) that can have an influence on social media activity. © The Author(s) 2015.

    The Korean journal published in English, Nuclear Engineering and Technology (here under NET) has been enlisted in the global citation database SCI E(Science Citation Index Expanded) of Thomson Reuters (past ISI), beginning with NET vol.39 No.1 (Feb. 2007). As of July 2009, the citation index of NET as reported by JCR (Journal Citation Report) based on the cumulative data from ISI (Institute for Scientific Information) reached to 0.991. This index ranks on 12{sup th} among the 33 journals in the area of nuclear science and technology in the science and technology covered by JCR, meaning fairly high impact factor. The following year 2010, however, witnessed the JCR figure dropping down to 0.465. The reason behind such drastic fall would be the decreased citation and in a lesser extent self-citation in 2010, in comparison with 2009, despite the increased number of paper publication. This study attempts to give an analysis as of the end of 2011 on the NET citation frequency in SCI Source Journal and the citation frequency by KAERI authors, together with the nationalities of NET authors and SCI journals that refer to NET most. Based on the analysis, the paper suggests some ways to promoting the position of NET as a journal in the international nuclear sector

    Development of effective quantitative indicators and methodologies to assess the outcomes of cross-disciplinary collaborative initiatives has the potential to improve scientific program management and scientific output. This article highlights an example of a prospective evaluation that has been developed to monitor and improve progress of the National Cancer Institute Physical Sciences—Oncology Centers (PS-OC) program. Study data, including collaboration information, was captured through progress reports and compiled using the web-based analytic database: Interdisciplinary Team Reporting, Analysis, and Query Resource. Analysis of collaborations was further supported by data from the Thomson Reuters Web of Science database, MEDLINE database, and a web-based survey. Integration of novel and standard data sources was augmented by the development of automated methods to mine investigator pre-award publications, assign investigator disciplines, and distinguish cross-disciplinary publication content. The results highlight increases in cross-disciplinary authorship collaborations from pre- to post-award years among the primary investigators and confirm that a majority of cross-disciplinary collaborations have resulted in publications with cross-disciplinary content that rank in the top third of their field. With these evaluation data, PS-OC Program officials have provided ongoing feedback to participating investigators to improve center productivity and thereby facilitate a more successful initiative. Future analysis will continue to expand these methods and metrics to adapt to new advances in research evaluation and changes in the program. PMID:24808632

  3. II: Through the Western Part of the City: Charlottenburg

    Science.gov (United States)

    Hoffmann, Dieter

    Until 1920 the city we now call Berlin was a collection of independent towns and villages — among them Charlottenburg, which was one of the most important and was the proud sister of Berlin, Prussia’s and Germany’s capital, where the wealthy and innovative bourgeoisie lived. Werner von Siemens, Germany’s pioneer in the modern electrical industry, was a prime example of that elite. His castle-like villa was located not far from today’s Ernst-Reuter-Platz at Otto-Suhr-Allee 10-16, and important parts of his enterprise expanded into the “meadows outside of Charlottenburg” during the second half of the 19th century. It was no accident that the efforts to unite Berlin’s two colleges for trade and construction (both founded around 1800) led to the foundation of a modern Technical College in Charlottenburg in 1879, today’s Technical University of Berlin. Its magnificent main building (figure 1), which was opened in 1882 by the German Emperor, was an expression of the great self-confidence of this new institution of higher learning and of Charlottenburg’s bourgeoisie. Although large parts of the building were destroyed by bombs during World War II, you can still get an impression of its monumentality from what survived at number 135 Strasse des 17. Juni.

The study finds that combined book value, earnings and dividends do not provide statistical significance effects on IFRS after adoption on the quality of accounting information. This could be possible, as dividends do not provide a significant effect in the presence of earnings. Furthermore, the audit big 4 quality provided an effect on the quality of accounting information because of IFRS adoption.

    Neonatal hyperbilirubinemia is frequently seen condition in the NICU. Oral zinc has been tried for the prevention of hyperbilirubinemia. To evaluate the role of oral zinc supplementation for reduction of neonatal hyperbilirubinemia in term and preterm infants. The literature search was done for various randomized control trial (RCT) by searching the Cochrane Central Register of Controlled Trials (CENTRAL), PubMed, EMBASE, Web of Science, Scopus, Index Copernicus, African Index Medicus (AIM), Thomson Reuters (ESCI), Chemical Abstracts Service (CAS) and other data base. This review included six RCT that fulfilled inclusion criteria. One study evaluated the role of zinc in very low birth weight (VLBW) infants and remaining enrolled neonates  ≥35 weeks of gestation. The dose of zinc varied from 5 to 20 mg/day and duration from 5-7 days. All the studies used zinc sulfate, only one study used zinc gluconate. The total neonates enrolled in these different RCT are 749. Role of zinc in the prevention of neonatal hyperbilirubinemia is not supported by the current evidence. Only one study was able to show reduction in the mean TSB level and requirement of phototherapy with zinc, and the remaining studies did not report any positive effect. None of the studies showed any effect on the duration of phototherapy, incidence of phototherapy, age of starting of phototherapy and any serious adverse effect.

    Modeling fluorescent emission from monomeric formaldehyde (H2CO) forms an integral part of our overall comprehensive program of measuring the volatile composition of comets through high-resolution (RP ~ 25,000) infrared spectroscopy using CSHELL at the IRTF and NIRSPEC at Keck II. The H2CO spectra contain lines from both the nu1 (symmetric CH2 stretch) and nu5 (asymmetric CH2 stretch) bands near 3.6 microns. We have acquired high-quality spectra of twelve Oort cloud comets, and at least six of these show clear emission from H2CO. We also detected H2CO with NIRSPEC in one Jupiter Family comet, 9P/Tempel 1, during Deep Impact observations. Our H2CO model, originally developed to interpret low-resolution spectra of comets Halley and Wilson (Reuter et al. 1989 Ap J 341:1045), predicts individual line intensities (g-factors) as a function of rotational temperature for approximately 1300 lines having energies up to approximately 400 cm^-1 above the ground state. Recently, it was validated through comparison with CSHELL spectra of C/2002 T7 (LINEAR), where newly developed analyses were applied to obtain robust determinations of both the rotational temperature and abundance of H2CO (DiSanti et al. 2006 Ap J 650:470). We are currently in the process of extending the model to higher rotational energy (i.e., higher rotational quantum number) in an attempt to improve the fit to high-J lines in our spectra of C/T7 and other comets. Results will be presented, and implications discussed.Modeling fluorescent emission from monomeric formaldehyde (H2CO) forms an integral part of our overall comprehensive program of measuring the volatile composition of comets through high-resolution (RP ~ 25,000) infrared spectroscopy using CSHELL at the IRTF and NIRSPEC at Keck II.

Coinciding with the development of the Biodiversity Heritage Library (BHL) in 2005, it became obvious there was a need to integrate the database converted Index Animalium, BHL's scanned taxonomic literature, and taxonomic intelligence (the algorithmic identification of binomial, Latinate name-strings). The challenges of working with legacy taxonomic citation, computer matching algorithms, and making connections have brought us to today's goal of making Sherborn available and linked to other datasets. Partnering with others to allow machine-to-machine communications the data is being examined for possible transformation into RDF markup and meeting the standards of Linked Open Data. SIL staff have partnered with Thomson Reuters and the Global Names Initiative to further enhance the Index Animalium data set. Thomson Reuters' staff is now working on integrating the species microcitation and species name in the ION: Index to Organism Names project; Richard Pyle (The Bishop Museum) is also working on further parsing of the text. The Index Animalium collaborative project's ultimate goal is to successful have researchers go seamlessly from the species name in either ION or the scanned pages of Index Animalium to the digitized original description in BHL - connecting taxonomic researchers to original authored species descriptions with just a click.

    18 F-flutemetamol uptake by brain tissue, measured by positron emission tomography (PET), is accepted by regulatory agencies like the Food and Drug Administration (FDA) and the European Medicine Agencies (EMA) for assessing amyloid load in people with dementia. Its added value is mainly demonstrated by excluding Alzheimer's pathology in an established dementia diagnosis. However, the National Institute on Aging and Alzheimer's Association (NIA-AA) revised the diagnostic criteria for Alzheimer's disease and the confidence in the diagnosis of mild cognitive impairment (MCI) due to Alzheimer's disease may be increased when using some amyloid biomarkers tests like 18 F-flutemetamol. These tests, added to the MCI core clinical criteria, might increase the diagnostic test accuracy (DTA) of a testing strategy. However, the DTA of 18 F-flutemetamol to predict the progression from MCI to Alzheimer's disease dementia (ADD) or other dementias has not yet been systematically evaluated.

  11. Effects of Sublethal Concentrations of Insecticides on the Functional Response of Two Mirid Generalist Predators.

    Angeliki F Martinou

    Full Text Available The use of agrochemicals particularly pesticides, can hamper the effectiveness of natural enemies, causing disruption in the ecosystem service of biological control. In the current study, the effects of the insecticides thiacloprid and chlorantraniliprole on the functional response curves were assessed for two mirid predator nymphs, Macrolophus pygmaeus Rambur and Nesidiocoris tenuis Reuter. In the absence of insecticides, both predators exhibited a type II functional response when feeding on eggs of the moth Ephestia kuehniella. N. tenuis seems to be a more efficient predator than M. pygmaeus, as model estimated handling time was significantly lower for the former than for the latter. Residual exposure of M. pygmaeus to sublethal concentrations of either insecticide was associated with a change in the asymptote but not the type of the functional response curve. Thiacloprid seems to be the least compatible with M. pygmaeus, as it led to both a significant reduction of the attack rate and an increase in handling time. In contrast, chlorantraniliprole exposure significantly increased the handling time, but not the attack rate of the predator. Residual exposure of N. tenuis to sublethal concentrations of either insecticide did not have a significant effect on the type nor the parameters of the functional response model. The results show that pesticide residues that do not have lethal effects on beneficial arthropods can reduce prey consumption depending on predator species and on likely risks associated with toxicity.

    The successful integration of chemical and biological control strategies for crop pests depends on a thorough evaluation of the effects of pesticides on the natural enemies of pests. A case-by-case review is difficult to achieve because of the many combinations of pests, natural enemies, and crops that need to be tested. Within this framework, we tested and compared seven insecticides representative of four different modes of action (MoAs) groups on closely related predators (Miridae): flubendiamide, spirotetramat, metaflumizone, and sulfoxaflor onNesidiocoris tenuisReuter and flubendiamide, spiromesifen, indoxacarb, and imidacloprid onMacrolophus basicornis(Stal). We follow the standardized methodology of the International Organization for Biological Control, a sequential testing exposure scheme. The lethal effect of each insecticide was evaluated in adults after three days of contact with treated surfaces in the laboratory, extended laboratory, and semifield tests (inert substrate, tomato leaves, and tomato plant as the treated surface, respectively). Flubendiamide, spiromesifen, and spirotetramat were classified as harmless (class 1), metaflumizone was slightly harmful (class 2) but persistent, indoxacarb was harmless (class 1), and sulfoxaflor and imidacloprid were toxic (class 4) and exhibited a long residual activity. Our results suggest similarities in the acute toxicities of insecticides from the same MoA group on related species of natural enemies. © The Authors 2016.

    Oldham, Paul; Hall, Stephen; Burton, Geoff

    2012-01-01

    This article uses data from Thomson Reuters Web of Science to map and analyse the scientific landscape for synthetic biology. The article draws on recent advances in data visualisation and analytics with the aim of informing upcoming international policy debates on the governance of synthetic biology by the Subsidiary Body on Scientific, Technical and Technological Advice (SBSTTA) of the United Nations Convention on Biological Diversity. We use mapping techniques to identify how synthetic biology can best be understood and the range of institutions, researchers and funding agencies involved. Debates under the Convention are likely to focus on a possible moratorium on the field release of synthetic organisms, cells or genomes. Based on the empirical evidence we propose that guidance could be provided to funding agencies to respect the letter and spirit of the Convention on Biological Diversity in making research investments. Building on the recommendations of the United States Presidential Commission for the Study of Bioethical Issues we demonstrate that it is possible to promote independent and transparent monitoring of developments in synthetic biology using modern information tools. In particular, public and policy understanding and engagement with synthetic biology can be enhanced through the use of online interactive tools. As a step forward in this process we make existing data on the scientific literature on synthetic biology available in an online interactive workbook so that researchers, policy makers and civil society can explore the data and draw conclusions for themselves.

    This study aimed at exploring the citation parameters of contact lenses articles published in the Ophthalmology thematic category of the Journal Citation Reports (JCR). The Thompson Reuters Web of Science database was accessed to record bibliometric information and citation parameters of all journals listed under the Ophthalmology area of the 2011 JCR edition, including the journals with main publication interests in the contact lens field. In addition, the same database was used to unveil all contact lens-related articles published in 2011 in the same thematic area, whereupon differences in citation parameters between those articles published in contact lens and non-contact lens-related journals were explored. Significant differences in some bibliometric indicators such as half-life and overall citation count were found between contact lens-related journals (shorter half-life and fewer citations) and the median values for the Ophthalmology thematic area of the JCR. Visual examination of all Ophthalmology journals uncovered a total of 156 contact lens-related articles, published in 28 different journals, with 27 articles each for Contact Lens & Anterior Eye, Eye & Contact Lens, and Optometry and Vision Science. Significant differences in citation parameters were encountered between those articles published in contact lens and non-contact lens source journals. These findings, which disclosed contact lenses to be a fertile area of research, may be of interest to researchers and institutions. Differences in bibliometric indicators are of relevance to avoid unwanted bias when conducting between- and within-discipline comparisons of articles, journals, and researchers.

    The unbalanced international scientific collaboration as cause of misleading information on the country's contribution to the scientific world output was analyzed. ESI Data Base (Thomson Reuters' InCites), covering the scientific production of 217 active countries in the period 2010-2014 was used. International collaboration implicates in a high percentage (33.1 %) of double-counted world articles, thus impacting qualitative data as citations, impact and impact relative to word. The countries were divided into three groups, according to their individual contribution to the world publications: Group I (24 countries, at least 1 %) representing 83.9 % of the total double-counted world articles. Group II (40 countries, 0.1-0.99 % each). Group III, 153 countries (70.5 %) with international collaboration were: Group I, 43.0 %; Group II, 55.8 % and Group III, 85.2 %. We concluded that very high and unbalanced international collaboration, as presented by many countries, misrepresent the importance of their scientific production, technological and social outputs. Furthermore, it jeopardizes qualitative outputs of the countries themselves, artificially increasing their scientific impact, affecting all fields and therefore, the whole world. The data confirm that when dealing with the qualitative contribution of countries, it is necessary to take in consideration the level of international cooperation because, as seen here, it can and in fact it does create false impression of the real contribution of countries.

    Full Text Available Abstract Background Tibia shaft fractures (TSF are common for men and women and cause substantial morbidity, healthcare use, and costs. The impact of nonunions on healthcare use and costs is poorly described. Our goal was to investigate patient characteristics and healthcare use and costs associated with TSF in patients with and without nonunion. Methods We retrospectively analyzed medical claims in large U.S. managed care claims databases (Thomson Reuters MarketScan®, 16 million lives. We studied patients ≥ 18 years old with a TSF diagnosis (ICD-9 codes: 823.20, 823.22, 823.30, 823.32 in 2006 with continuous pharmaceutical and medical benefit enrollment 1 year prior and 2 years post-fracture. Nonunion was defined by ICD-9 code 733.82 (after the TSF date. Results Among the 853 patients with TSF, 99 (12% had nonunion. Patients with nonunion had more comorbidities (30 vs. 21, pre-fracture and were more likely to have their TSF open (87% vs. 70% than those without nonunion. Patients with nonunion were more likely to have additional fractures during the 2-year follow-up (of lower limb [88.9% vs. 69.5%, P  Conclusions Nonunions in TSF’s are associated with substantial healthcare resource use, common use of strong opioids, and high per-patient costs. Open fractures are associated with higher likelihood of nonunion than closed ones. Effective screening of nonunion risk may decrease this morbidity and subsequent healthcare resource use and costs.

    The demand for mobile learning in the medical science educational program is increasing. The present review study gathers evidence highlighted by the experimental studies on the educational effects of mobile learning for medical science students. The study was carried out as a systematic literature search published from 2007 to July 2017 in the databases PubMed/Medline, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Web of Knowledge (Thomson Reuters) , Educational Resources and Information Center (ERIC), EMBASE (Elsevier), Cochrane library, PsycINFO and Google Scholar. To examine quality of the articles, a tool validated by the BEME Review was employed. Totally, 21 papers entered the study. Three main themes emerged from the content of papers: (1) improvement in student clinical competency and confidence, (2) acquisition and enhancing of students' theoretical knowledge, and (3) students' positive attitudes to and perception of mobile learning. Level 2B of Kirkpatrick hierarchy had been examined by all the papers and seven of them had reported two or more outcome levels, but level 4 was not reported in the papers. Our review showed that the students of medical sciences had positive response and attitudes to mobile learning. Moreover, implementation of mobile learning in medical sciences program might lead to valuable educational benefits and improve clinical competence and confidence along with theoretical knowledge, attitudes, and perception of mobile learning. The results indicated that mobile learning strategy in medical education can positively affect learning in all three domains of Bloom's Taxonomy.

    Full Text Available As of July 2015, 28 Philippine scientific journals out of 777 Philippine scholarly journals are listed in the master journal lists of Thomson Reuters (TR, Scopus, or both. Of these scientific journals, thirteen are published by universities, two by government institutions, ten by professional organizations and three by private for-profit or non-profit organizations. Nineteen of these journals are over 25 years old, with the Philippine Journal of Science and the Philippine Agricultural Scientist being the oldest at 108 and 103 years in publication, respectively. Scientific journals in the Philippines, like other countries in Asia, face various increasing challenges. Among these challenges are getting listed in the master journal lists and citation databases of TR, Scopus, or both; obtaining funding; reaching a wider readership; attaining higher impact factors; competing for papers; and increased submission of manuscripts from outside the country. To promote the improvement of local journals, the National Academy of Science and Technology Philippines has given outstanding publication awards for scientific papers published in local journals for the past two decades. The Philippine Commission on Higher Education has accredited local journals that are included in either TR and Scopus journal master lists, and provides monetary incentives to accredited journals. Training workshops on scientific article writing and editorial management are conducted for researchers and editors by universities and professional and government organizations. A network of Philippine science editors has been formed to work together to upgrade and modernize selected journals to international standards.

    Digital Object Identifiers (DOIs) are applied to selected data sets at the NASA Goddard Earth Sciences Data and Information Services Center (GES DISC). The DOI system provides an Internet resolution service for unique and persistent identifiers of digital objects. Products assigned DOIs include data from the NASA MEaSUREs Program, the Earth Observing System (EOS) Aqua Atmospheric Infrared Sounder (AIRS) and EOS Aura High Resolution Dynamics Limb Sounder (HIRDLS). DOIs are acquired and registered through EZID, California Digital Library and DataCite. GES DISC hosts a data set landing page associated with each DOI containing information on and access to the data including a recommended data citation when using the product in research or applications. This work includes participation with the earth science community (e.g., Earth Science Information Partners (ESIP) Federation) and the NASA Earth Science Data and Information System (ESDIS) Project to identify, establish and implement best practices for assigning DOIs and managing supporting information, including metadata, for earth science data sets. Future work includes (1) coordination with NASA mission Science Teams and other data providers on the assignment of DOIs for other GES DISC data holdings, particularly for future missions such as Orbiting Carbon Observatory -2 and -3 (OCO-2, OCO-3) and projects (MEaSUREs 2012), (2) construction of landing pages that are both human and machine readable, and (3) pursuing the linking of data and publications with tools such as the Thomson Reuters Data Citation Index.

    Medical education is an essential domain to produce physicians with high standards of medical knowledge, skills and professionalism in medical practice. This study aimed to investigate the research progress and prospects of GCC countries in medical education during the period 1996-2013. In this study, the research papers published in various global scientific journals during the period 1996-2013 were accessed. We recorded the total number of research documents having an affiliation with GCC Countries including Saudi Arabia, Bahrain, Kuwait, Qatar, United Arab Emirates and Oman. The main source for information was Institute of Scientific Information (ISI) Web of Science, Thomson Reuters. In ISI-Web of Science, Saudi Arabia contributed 40797 research papers, Kuwait 1666, United Arab Emirates 3045, Qatar 4265, Bahrain 1666 and Oman 4848 research papers. However, in Medical Education only Saudi Arabia contributed 323 (0.79%) research papers, Kuwait 52 (0.03%), United Arab Emirates 41(0.01%), Qatar 37(0.008%), Bahrain 28 (0.06%) and Oman 22 (0.45%) research papers in in ISI indexed journals. In medical education the Hirsch index (h-index) of Saudi Arabia is 14, United Arab Emirates 14, Kuwait 11, Qatar 8, Bahrain 8 and Oman 5. GCC countries produced very little research in medical education during the period 1996-2013. They must improve their research outcomes in medical education to produce better physicians to enhance the standards in medical practice in the region.

    The tomato leafminer, Tuta absoluta (Meyrick), had established in Israel by 2010, attacking both open-field tomatoes and greenhouse crops.We searched for its natural enemies in open-field tomatoes, and tried to determine their potential for controlling this pest. We surveyed the local natural enemies in open tomato fields and measured their impact on pest populations in an unsprayed field. We assessed the suppressive ability of the dominant hemipteran predator, Nesidiocoris tenuis Reuter, against T. absoluta under controlled laboratory conditions and evaluated the impact of its augmentation on T. absoluta control in open-field tomatoes. We found five natural enemy species:the predator, N. tenuis, two braconids, and two eulophids. Predation accounted for 64.5±9.2% (mean ± SE) of T. absoluta larval mortality, whereas parasitism accounted for 20.96±7.5%. Together, they eliminated the pest population at tomato harvest time. Under controlled conditions, predation by N. tenuis rose from 58 to 72% with increased density of T. absoluta, suggesting positive density dependence. The reduction of T. absoluta (83%) by N. tenuis was higher than that of Bemisia tabaci (32%), suggesting a preference of N. tenuis for T. absoluta. Augmentation of N.tenuis was as effective as conventional treatment insecticide treatment, and plant damage was low and did not seem to affect yield. Results indicate that reduced pesticide use enables indigenous natural enemies, particularly N.tenuis, to successfully control T. absoluta and prevent crop damage in open-field tomatoes.

    Background The past 3 decades have witnessed a boost in science development in China; in parallel, more and more Chinese scientific journals are indexed by the Journal Citation Reports issued by Thomson Reuters (SCI). Evaluation of the performance of these Chinese SCI journals is necessary and helpful to improve their quality. This study aimed to evaluate these journals by calculating various journal self-citation rates, which are important parameters influencing a journal impact factor. Methodology/Principal Findings We defined three journal self-citation rates, and studied these rates for 99 Chinese scientific journals, almost exhausting all Chinese SCI journals currently available. Likewise, we selected 99 non-Chinese international (abbreviated as ‘world’) journals, with each being in the same JCR subject category and having similar impact factors as their Chinese counterparts. Generally, Chinese journals tended to be higher in all the three self-citation rates than world journal counterparts. Particularly, a few Chinese scientific journals had much higher self-citation rates. Conclusions/Significance Our results show that generally Chinese scientific journals have higher self-citation rates than those of world journals. Consequently, Chinese scientific journals tend to have lower visibility and are more isolated in the relevant fields. Considering the fact that sciences are rapidly developing in China and so are Chinese scientific journals, we expect that the differences of journal self-citation rates between Chinese and world scientific journals will gradually disappear in the future. Some suggestions to solve the problems are presented. PMID:23173041

    Full Text Available La creación de sistemas integradores de productos de investigación, como el Researcher ID de Thomson Reuters, ha sido una necesidad emergente debido a lo complejo que es para los investigadores demostrar de manera periódica el impacto y difusión de su investigación. Sin embargo, estos sistemas se alimentan de información proveniente de las diversas bases de datos y cada vez son más inclusivos para captar productos de investigación. Varios estudios bibliométricos han demostrado que las bases de datos contienen imprecisiones de varios tipos, que afectan directamente a los sistemas integradores. Como consecuencia, se plantea este estudio descriptivo con el fin de analizar la precisión de los registros del Researcher ID de los miembros del consejo de www.psy-wos.es y de una muestra de usuarios de esta página para cotejar los registros con los contenidos en la base de datos Web of Science, diferenciándolos de contenidos ajenos a esta base de datos. Los resultados reflejan que existen imprecisiones y errores considerables en los Researcher ID de la muestra analizada, tales como duplicidad de registros y la inclusión de registros ajenos a la Web of Science.

    This study focuses on retraction notices from two major Latin American/Caribbean indexing databases: SciELO and LILACS. SciELO includes open scientific journals published mostly in Latin America/the Caribbean, from which 10 % are also indexed by Thomson Reuters Web of Knowledge Journal of Citation Reports (JCR). LILACS has a similar geographical coverage and includes dissertations and conference/symposia proceedings, but it is limited to publications in the health sciences. A search for retraction notices was performed in these two databases using the keywords "retracted", "retraction" "withdrawal", "withdrawn", "removed" and "redress". Documents were manually checked to identify those that actually referred to retractions, which were then analyzed and categorized according to the reasons alleged in the notices. Dates of publication/retraction and time to retraction were also recorded. Searching procedures were performed between June and December 2014. Thirty-one retraction notices were identified, fifteen of which were in JCR-indexed journals. "Plagiarism" was alleged in six retractions of this group. Among the non-JCR journals, retraction reasons were alleged in fourteen cases, twelve of which were attributed to "plagiarism". The proportion of retracted articles for the SciELO database was approximately 0.005 %. The reasons alleged in retraction notices may be used as signposts to inform discussions in Latin America on plagiarism and research integrity. At the international level, these results suggest that the correction of the literature is becoming global and is not limited to mainstream international publications.

    Full Text Available Physical factors and health and safety issues and training are the most effective and most fundamental natural growth factor in terms of physical, mental and educational development in students. This study was designed to obtain anthropometric dimensions of Iranian primary school student. We searched international databases such as Thomson Reuters, PubMed, Scopus, EMBASE, Cochrane Library, and Iranian databases such as SID, Magiran, Iranmedex using a searching strategy during 2000 to 2016 years. Database without language restriction, since 2000 sources, with the MeSH term "Anthropometric data" AND "Iranian primary school children". At first, in the initial search,115 articles were found, and finally, 22 of them which were related to the subject of this research were used. This study showed significant differences in a set of anthropometric dimensions with regard to gender, age and ethnicity.Alsothis study indicates that there is a significant difference between the minimum and maximum acceptable dimensions and those of the available furniture (p < 0.05.According to the results of this study, difference between genders and among different ethnicities should be taken into account by designers and manufacturers of school furniture. In many schools, there is not proportion between students’ anthropometric dimensions and the dimensions of existing tables and benches. Thus, it is suggested that required efforts are done to design educational furniture such as table and bench for various grades of elementary level in every region according to the existing anthropometric dimensions database.

Embora a literatura de relações interorganizacionais reconheça o papel crítico do poder, uma sucessão de teorias com diferentes perspectivas empíricas, teóricas e metodológicas demonstra que ainda há uma falta de consenso a respeito de quais atores detêm o poder nestes contextos. São questões de pesquisa: Como os recentes estudos em redes de negócio abordam o poder? Quais as implicações dos principais paradigmas teóricos utilizados? A análise das publicações selecionadas aponta para a multiplicidade de perspectivas teóricas na abordagem do poder na literatura e indica um aumento do interesse no tema ao longo do tempo. As principais perspectivas teóricas identificadas são a Teoria da Dependência de Recursos; a Teoria da Troca em Redes; e a Teoria de Custos de Transação. Essas teorias são analisadas sob o quadro teórico e um conjunto de proposições conceituais é definido, de modo a avaliar as implicações dos paradigmas associados a cada corrente teórica.

    Full Text Available Using the InCites tool of Thomson Reuters, this study compares normalized citation impact values calculated for China, Japan, France, Germany, United States, and the UK throughout the time period from 1981 to 2010. InCites offers a unique opportunity to study the normalized citation impacts of countries using (i a long publication window (1981 to 2010, (ii a differentiation in (broad or more narrow subject areas, and (iii allowing for the use of statistical procedures in order to obtain an insightful investigation of national citation trends across the years. Using four broad categories, our results show significantly increasing trends in citation impact values for France, the UK, and especially Germany across the last thirty years in all areas. The citation impact of papers from China is still at a relatively low level (mostly below the world average, but the country follows an increasing trend line. The USA exhibits a stable pattern of high citation impact values across the years. With small impact differences between the publication years, the US trend is increasing in engineering and technology but decreasing in medical and health sciences as well as in agricultural sciences. Similar to the USA, Japan follows increasing as well as decreasing trends in different subject areas, but the variability across the years is small. In most of the years, papers from Japan perform below or approximately at the world average in each subject area.

    Full Text Available We aimed to analyze the global scientific output of regulatory T-cell (Treg research and built a model to qualitatively and quantitatively evaluate publications from 2000 to 2015. Data were obtained from the Web of Science Core Collection (WoSCC of Thomson Reuters on January 1, 2016. The bibliometric method and Citespace III were used to analyze authors, journals, publication outputs, institutions, countries, research areas, research hotspots, and trends. In total, we identified 35,741 publications on Treg research from 2000 to 2015, and observed that the annual publication rate increased with time. The Journal of Immunology published the highest number of articles, the leading country was the USA, and the leading institute was Harvard University. Sakaguchi, Hori, Fontenot, and Wang were the top authors in Treg research. Immunology accounted for the highest number of publications, followed by oncology, experimental medicine, cell biology, and hematology. Keyword analysis indicated that autoimmunity, inflammation, cytokine, gene expression, foxp3, and immunotherapy were the research hotspots, whereas autoimmune inflammation, gene therapy, granzyme B, RORγt, and th17 were the frontiers of Treg research. This bibliometric analysis revealed that Treg-related studies are still research hotspots, and that Treg-related clinical therapies are the research frontiers; however, further study and collaborations are needed worldwide. Overall, our findings provide valuable information for the editors of immunology journals to identify new perspectives and shape future research directions.

    The well documented susceptibility of burn patients to acquired infections via damaged skin mandates application of antimicrobial agents. These agents are dissolved in various vehicles that augment skin absorption thus allowing greater efficacy. Polyethylene glycol (PEG) and Propylene glycol (PropG) are among the most commonly used vehicles, and both have been used in numerous medications and cosmetic products over the past few decades. Rarely, burn patients treated with agents containing these glycols present with a life threatening systemic toxidrome of hyperosmolar metabolic acidosis. We present a systematic review of outcomes in burn patients treated with similar agents. Relevant studies were identified through systematic searches conducted in MEDLINE (Ovid), Embase (Ovid), CENTRAL (Ovid), and Web of Science (Thomson Reuters), from database inception to August 4th, 2016. All publications of clinical burn patient studies included at least one arm receiving a glycol based topical therapy. A total of 61 studies involving 10,282 patients and 4 different antimicrobial medications fulfilled the inclusion criteria. Nine burn patients (0.09%) were documented to present with hyperosmolar metabolic acidosis during topical silver sulfadiazine treatment. Propylene glycol isolated from their blood accounted for the high osmole gap. This first systematic review found very few cases of documented hyperosmolar metabolic acidosis, all within one study that had set to specifically explore this toxidrome. High index of suspicion with frequent osmolar gap monitoring may help identify future toxicities in a timely manner. Copyright © 2017 Elsevier Ltd and ISBI. All rights reserved.

    A significant amount of data concerning maternal-fetal damage arising from the exertion of Kristeller maneuvers (KMs) or fundal pressure (FP) go unreleased due to medicolegal implications. For this reason, the paper gathers information as to the real magnitude of litigation related to FP-induced damages and injuries. The authors have undertaken a research in order to include general search engines (PubMed-Medline, Cochrane, Embase, Google, GyneWeb) and legal databases (De Jure, Italian database of jurisprudence daily update; Westlaw, Thomson Reuters, American ruling database and Bailii, UK Court Ruling Database). Results confirm said phenomenon to be more wide ranging than it appears through official channels. Several courts of law, both in the United States of America (USA) and in European Union (EU) Member States as well, have ruled against the use of the maneuver itself, assuming a stance conducive to a presumption of guilt against those doctors and healthcare providers who resorted to KMs or FP during deliveries. Given how rife FP is in mainstream obstetric practice, it is as if there were a wide gap between obstetric real-life and what official jurisprudence and healthcare institutions-sanctioned official practices are. The authors think that it would be desirable to draft specifically targeted guidelines or recommendations on maneuvers during vaginal delivery, in which to point out exactly what kinds of maneuvering techniques are to be absolutely banned and what maneuvers are to be allowed, and under what conditions their application can be considered appropriate.

    Full Text Available As a key facet of sustainable development, environmental, social and governance (ESG discretion on stock market investment decision is gaining prevalence following the global financial crisis. ESG considers the sustainable return, risk reduction, and accountability aspects of investments. This study is an exploration of the individual stock market investors’ preferences for ESG issues and the influence that purpose of investment has on investment decision-making, by testing the investment horizon as a moderator. The theoretical background was taken from the theory of planned behavior (TPB, goal setting theory (GST, and the behavioral asset pricing model (BAPM. The study uses the sequential mix method of research, starting with an interview followed by a survey, which was conducted among individual stock market investors in Bangladesh, using simple random sampling. Structural equation modeling (SEM analysis was carried out using Warp PLS version 6.0. The key findings of this study delineate the effect of ESG issues and the purpose of investment on investment decision-making. The contribution of the study signifies the moderating role of the investment horizon, which confirms the importance of the long-term horizon as a time and risk diversification factor. The sparse utilization of the United Nations Global Compact (UNGC (2004 and Thomson Reuters Corporate Responsibility Index (TRCRI (2013 as measurement scales in this study is mentioned. This study has made practical contributions for managers, investors, and regulators.

    The use of agrochemicals particularly pesticides, can hamper the effectiveness of natural enemies, causing disruption in the ecosystem service of biological control. In the current study, the effects of the insecticides thiacloprid and chlorantraniliprole on the functional response curves were assessed for two mirid predator nymphs, Macrolophus pygmaeus Rambur and Nesidiocoris tenuis Reuter. In the absence of insecticides, both predators exhibited a type II functional response when feeding on eggs of the moth Ephestia kuehniella. N. tenuis seems to be a more efficient predator than M. pygmaeus, as model estimated handling time was significantly lower for the former than for the latter. Residual exposure of M. pygmaeus to sublethal concentrations of either insecticide was associated with a change in the asymptote but not the type of the functional response curve. Thiacloprid seems to be the least compatible with M. pygmaeus, as it led to both a significant reduction of the attack rate and an increase in handling time. In contrast, chlorantraniliprole exposure significantly increased the handling time, but not the attack rate of the predator. Residual exposure of N. tenuis to sublethal concentrations of either insecticide did not have a significant effect on the type nor the parameters of the functional response model. The results show that pesticide residues that do not have lethal effects on beneficial arthropods can reduce prey consumption depending on predator species and on likely risks associated with toxicity.

    The dynamic, decentralized world-wide-web has become an essential part of scientific research and communication. Researchers create thousands of web sites every year to share software, data and services. These valuable resources tend to disappear over time. The problem has been documented in many subject areas. Our goal is to conduct a cross-disciplinary investigation of the problem and test the effectiveness of existing remedies. We accessed 14,489 unique web pages found in the abstracts within Thomson Reuters' Web of Science citation index that were published between 1996 and 2010 and found that the median lifespan of these web pages was 9.3 years with 62% of them being archived. Survival analysis and logistic regression were used to find significant predictors of URL lifespan. The availability of a web page is most dependent on the time it is published and the top-level domain names. Similar statistical analysis revealed biases in current solutions: the Internet Archive favors web pages with fewer layers in the Universal Resource Locator (URL) while WebCite is significantly influenced by the source of publication. We also created a prototype for a process to submit web pages to the archives and increased coverage of our list of scientific webpages in the Internet Archive and WebCite by 22% and 255%, respectively. Our results show that link decay continues to be a problem across different disciplines and that current solutions for static web pages are helping and can be improved.

    Currently there is a growing interest in studying systemic conditions with impact on the periodontium. The aim of this article is to determinate if there is a relation between Hashimoto's thyroiditis and periodontal disease. Founded on periodontology based on evidence and in the combination of the keywords: 'Hashimoto disease'; 'Hypothyroidism'; 'Periodontal disease'; 'Systemic Diseases'; a search and evaluation of articles was conducted in Medline, Scopus and Thomson Reuters databases, selecting 30 articles for integral analysis. There have been developed several studies, searching for a better comprehension about the complexity and pathogenesis of periodontal diseases, associated them to multiple systemic conditions. Actually, the relationship that is best described in the literature is the one with rheumatoid arthritis; however, other relations have been pointed, such as Hashimoto's thyroiditis. The identification of multiple etiopathogenic mechanisms common to Hashimoto's thyroiditis and periodontal disease allow to suspect of a relation between them. Some of these mechanisms include the proliferation of lymphocytes T helper 1 and T helper 17 and their impact on the periodontium, the dysfunction of vascular endothelium in gingival microcirculation and the influence of hypothyroidism on bone metabolism, namely on the alveolar bone. There is biological plausibility to support the establishment of an association between Hashimoto's thyroiditis and periodontal disease. However, there are not enough studies to support the existence of a causal nexus between these two pathologies, so, in the future, more studies should be conducted to determinate there relation and interaction.

    Full Text Available The review discusses the proceedings of the 2003 conference on practice theory in the social sciences, published as "Doing Culture". It especially makes room for the presentation of the theoretically oriented parts of the volume—texts either comparing two different theories or working at the further development of practice theory. An overview is given about the other parts of the volume which present case studies or singular aspects. Concluding the review, open questions from the different texts are put together. "Doing Culture" is helpful if one wants to be informed about the current state of the "practical turn" in German-language sociology of technology and media. The heterogeneity of the volume—typical of congress proceedings—shows, on the one hand, the breadth of the contemporary discussion but shows, on the other hand, that "practice theory" as one singular theory with a widely used vocabulary still does not exist.

    Hong Kong is a metropolitan city located on the southern coast of China with a population of some six million. About 90% of the population is concentrated in heavily built-up residential and commercial areas, which accounts for less than 50% of the total area in the territory. Hong Kong Observatory, 134A Nathan Road, Kowloon, Hong Kong, China. In order to understand the spatial variations in the environmental radiation levels in Hong Kong, the Hong Kong Observatory (HKO) in early 1999 conducted a study of the environmental gamma absorbed dose rate in air. The study combined data collected by the HKO radiation monitoring network (RMN) and data from a comprehensive territory-wide radiological survey conducted in January and February 1999. The RMN of ten stations each equipped with a Reuter-Stokes Model RSS-1013 HPIC has been in operation since 1987 to continuously monitor the environmental radiation levels over the territory as part of the emergency monitoring programme for response to nuclear accidents at a nearby nuclear power station. The terrestrial component of the environmental radiation field was estimated by subtracting from the measurements the cosmic contribution, which is determined to be about 39 nGy/h from measurements conducted over two large fresh water reservoirs. The RMN data with the long history was analysed to derive the seasonal variations in the environmental radiation levels. On average the environmental gamma absorbed dose rate in air in January and February is 1.03 times of the annual figure. This seasonal correction was applied to the results of the year 1999 survey. As the radiation field in the heavily built-up areas is enhanced by contribution from buildings, in the territory-wide survey measurements were made both in the open field and built-up areas. The territory of Hong Kong was divided into 42 grid boxes of 5 km x 5 km for open field and 61 grid boxes of 2.5 km x 2.5 km for built-up areas according to the population and land use. A

    To analyze critically the effectiveness and value of bibliometric indicators in journals of Surgery or Cardiovacular Surgery in the context of the postgraduate programs of CAPES Medicine III. A sampling with 16 academic programs and one professional master of Medicine III, encompassing the General and Digestive System Surgery, Cardiovascular Surgery and Multidisciplinary courses with such contents, was evaluated. Thomson Reuters/ISI (JCR), Elsevier/Scopus (SJR), and also Scielo databases were used. Only in seven programs, the teachers had an average of Qualis A1 articles greater than the others strata. Eleven journals in the surgical area are in stratum A1 (5%) and it reaches 25% in Cardiovascular Surgery. Among the six journals with the largest number of publications Qualis A1 in area Medicine III, five are from non-specific areas. The Acta Cirúrgica Brasileira represented 58% of the publications in the stratum A2. There are some obstacles in the Qualis classification with little uniformity among the Medicine areas I, II and III. A permanent committee should be set to update the Qualis, composed by the three medical areas. It should be considered using other index databases and the unification of the Qualis criteria for journals in medicine. Rating criteria of multi and transdisciplinary journals need to be reviewed. It is essential an institutional financial support for national journals chosen by peers aiming to provide a full computerization process and a professional reviewer of the English language, in order to increase the impact factor.

    Citation analysis as one of the most widely used methods of bibliometrics can be used for computing the various impact measures for scholars based on data from citation databases. Journal Citation Reports (JCR) from Thomson Reuters provides annual report in the form of impact factor (IF) for each journal. We aimed to evaluate the citation parameters of Hepatitis Monthly by JCR in 2010 and compare them with GS and Sc. All articles of Hepat Mon published in 2009 and 2008 which had been cited in 2010 in three databases including WoS, Sc and GS gathered in a spreadsheet. The IFs were manually calculated. Among the 104 total published articles the accuracy rates of GS and Sc in recording the total number of articles was 96% and 87.5%. There was a difference between IFs among the three databases (0.793 in ISI [Institute for Scientific Information], 0.945 in Sc and 0.85 GS). The missing rate of citations in ISI was 4% totally. Original articles were the main cited types, whereas, guidelines and clinical challenges were the least ones. None of the three databases succeed to record all articles published in the journal. Despite high sensitivity of GS comparing to Sc, it cannot be a reliable source for indexing since GS has lack of screening in the data collection and low specificity. Using an average of three IFs is suggested to find the correct IF. Editors should be more aware on the role of original articles in increasing IF and the potential efficacy of review articles in long term impact factor.

    The aim of this study was to perform a bibliometric analysis of EPI-SCAN and IBERPOC studies using the Science Citation Index and Scopus databases, and to determine the overall impact with the impact of smoking on IBERPOC as a secondary objective. A general searching was conducted in Science Citation Index-Expanded through the Web of Science (WoS) (Thomson Reuters) platform and Scopus on 23 March 2015. The search strategy included the terms "iberpoc" OR "episcan" was performed on 15 October 2015. A total of 24 publications were obtained; 13 from IBERPOC study (9 on "COPD" and 4 for "tobacco"), with 11 from the EPI-SCAN (All COPD) study. A total of 841 WoS citations were obtained (445 IBERPOC [99 of tobacco]), and 1,442 from Scopus (963 IBERPOC [144 tobacco]). The theme "tobacco" contributed with 22.24% and 14.95% of total citations in WoS and Scopus, respectively to the IBERPOC study. It was found that Scopus citations were newer, and a similar impact from both WoS studies was detected, although the IBERPOC impact was greater in Scopus. Collaborative networks of institutions and authors of both studies were identified. There is an important productivity and impact of both studies. Scopus citations are newer than those in WoS. The "tobacco" variable added IBERPOC impact and visibility. There was high density, accessibility, and cohesion in collaborative networks of both studies.

  1. Obesity and Aging: Consequences for Cognition, Brain Structure, and Brain Function.

    Bischof, Gérard N; Park, Denise C

    2015-01-01

    This review focuses on the relationship between obesity and aging and how these interact to affect cognitive function. The topics covered are guided by the Scaffolding Theory of Aging and Cognition (STAC [Park and Reuter-Lorenz. Annu Rev Psychol 2009;60:173-96]-a conceptual model designed to relate brain structure and function to one's level of cognitive ability. The initial literature search was focused on normal aging and was guided by the key words, "aging, cognition, and obesity" in PubMed. In a second search, we added key words related to neuropathology including words "Alzheimer's disease," "vascular dementia," and "mild cognitive impairment." The data suggest that being overweight or obese in midlife may be more detrimental to subsequent age-related cognitive decline than being overweight or obese at later stages of the life span. These effects are likely mediated by the accelerated effects obesity has on the integrity of neural structures, including both gray and white matter. Further epidemiological studies have provided evidence that obesity in midlife is linked to an increased risk for Alzheimer's disease and vascular dementia, most likely via an increased accumulation of Alzheimer's disease pathology. Although it is clear that obesity negatively affects cognition, more work is needed to better understand how aging plays a role and how brain structure and brain function might mediate the relationship of obesity and age on cognition. Guided by the STAC and the STAC-R models, we provide a roadmap for future investigations of the role of obesity on cognition across the life span.

    The aim of this study is to determine the relative value and contribution of searching different sources to identify adverse effects data. The process of updating a systematic review and meta-analysis of thiazolidinedione-related fractures in patients with type 2 diabetes mellitus was used as a case study. For each source searched, a record was made for each relevant reference included in the review noting whether it was retrieved with the search strategy used and whether it was available but not retrieved. The sensitivity, precision, and number needed to read from searching each source and from different combinations of sources were also calculated. There were 58 relevant references which presented sufficient numerical data to be included in a meta-analysis of fractures and bone mineral density. The highest number of relevant references were retrieved from Science Citation Index (SCI) (35), followed by BIOSIS Previews (27) and EMBASE (24). The precision of the searches varied from 0.88% (Scirus) to 41.67% (CENTRAL). With the search strategies used, the minimum combination of sources required to retrieve all the relevant references was; the GlaxoSmithKline (GSK) website, Science Citation Index (SCI), EMBASE, BIOSIS Previews, British Library Direct, Medscape DrugInfo, handsearching and reference checking, AHFS First, and Thomson Reuters Integrity or Conference Papers Index (CPI). In order to identify all the relevant references for this case study a number of different sources needed to be searched. The minimum combination of sources required to identify all the relevant references did not include MEDLINE.

    Since last decade, Saudi Arabia has been swiftly moving ahead to promote an education and research in the country. This study aimed to investigate the research outcome of Saudi Arabia in medical sciences during the period 1996-2012. In this study, the research papers published in various global science journals during the period 1996-2012 were accessed. We recorded the total number of research documents having an affiliation with Saudi Arabia. The main source for information was Institute of Scientific Information (ISI) Web of Science, Thomson Reuters and SCI-mago/Scopus. In global science data base, Saudi Arabia contributed 103804 documents in all science and social sciences. In medicine the total number of research papers from Saudi Arabia are 16196, citable documents 14732, total citations 102827, citations per documents 6.36 and Hirsch index (h-index) is 92. However, in combined medical and allied health sciences the total number of research papers are 27246, citable documents 25416, total citations 181999, mean citations per documents 7.07 and mean h-index is 41.44. Furthermore, Saudi Arabia contributed 40797 research documents in ISI indexed journals only and also 151 research documents in highly reputable and towering science journals. Saudi Arabia's research performance in global medical sciences has markedly increased during the period 2006-2012. The research publications are continuously on mounting path; however, the number of citations has decreased. The country improved its regional as well as international research rankings and graded 45 in the world in year 2012.

    The aim of the study was to quantify the scientific productivity of researchers, organizations, and regions in Spain that publish articles on implantology in dental journals indexed in Journal Citation Reports. A search was conducted among the core collection of Thomson Reuters' Web of Science database, on the basis of its broad thematic and geographic coverage of health sciences. The search identified original articles - the main vehicle for the dissemination of research results. The search was conducted in July 2016, applying the truncated search term 'implant*' to locate original articles on implantology and its derivative forms. The search was conducted within the topic field (title, keywords and abstract) and two inclusion criteria were applied: documents denominated as articles were included; and articles categorized as Web of Science Medicine Dentistry and Oral Surgery. Finally only articles for which one of the participating organizations was located in Spain were selected. The final search identified a total of 774 records. The period 1988 to 2015 saw an exponential growth in scientific production, especially during the last 10 years. Clinical Oral Implants Research and Medicina Oral Patologia Oral y Cirugia Bucal (Oral Medicine, Oral Pathology, and Oral Surgery) were the most productive journals. Collaborative networks among authors and among institutions increased and this increase was related to the improving quality of the publications. Bibliometric analysis revealed a significant growth in the quantity and quality of Spanish implantology literature. Most key bibliometric indicators demonstrated upward trends. Key words: Bibliometric analysis, publication, keywords, implantology, implant.

    Although commensal microbes have been shown to modulate host immune responses, many of the bacterial factors that mediate immune regulation remain unidentified. Select strains of human-derived Lactobacillus reuteri synthesize immunomodulins that potently inhibit production of the inflammatory cytokine TNF. In this study, genetic and genomic approaches were used to identify and investigate L. reuteri genes required or human TNF immunomodulatory activity. Analysis of membrane fatty acids from multiple L. reuteri strains cultured in MRS medium showed that only TNF inhibitory strains produced the cyclopropane fatty acid (CFA) lactobacillic acid. The enzyme cyclopropane fatty acid synthase is required for synthesis of CFAs such as lactobacillic acid, therefore the cfa gene was inactivated and supernatants from the cfa mutant strain were assayed for TNF inhibitory activity. We found that supernatants from the wild-type strain, but not the cfa mutant, suppressed TNF production by activated THP-1 human monocytoid cells Although this suggested a direct role for lactobacillic acid in immunomodulation, purified lactobacillic acid did not suppress TNF at physiologically relevant concentrations. We further analyzed TNF inhibitory and TNF non-inhibitory strains under different growth conditions and found that lactobacillic acid production did not correlate with TNF inhibition. These results indicate that cfa indirectly contributed to L. reuter immunomodulatory activity and suggest that other mechanisms, such as decreased membrane fluidity or altered expression of immunomodulins, result in the loss of TNF inhibitory activity. By increasing our understanding of immunomodulation by probiotic species, beneficial microbes can be rationally selected to alleviate intestinal inflammation.

  7. Carbon futures and macroeconomic risk factors. A view from the EU ETS

    International Nuclear Information System (INIS)

    Chevallier, Julien

    2009-01-01

    This article examines the empirical relationship between the returns on carbon futures - a new class of commodity assets traded since 2005 on the European Union Emissions Trading Scheme (EU ETS) - and changes in macroeconomic conditions. By using variables which possess forecast power for equity and commodity returns, we document that carbon futures returns may be weakly forecast on the basis of two variables from the stock and bond markets, i.e. equity dividend yields and the 'junk bond' premium. Our results also suggest that the forecast abilities of two variables related to interest rates variation and economic trends on global commodity markets, respectively the U.S. Treasury bill yields and the excess return on the Reuters/CRB Index, are not robust on the carbon market. This latter result reinforces the belief that the EU ETS is currently operating as a very specific commodity market, with distinct fundamentals linked to allowance supply and power demand. The sensitivity of carbon futures to macroeconomic influences is carefully identified following a sub-sample decomposition before and after August 2007, which attempts to take into account the potential impact of the 'credit crunch' crisis. Collectively, these results challenge the market observers' viewpoint that carbon futures prices are immediately correlated with changes in the macroeconomic environment, and rather suggest that the carbon market is only remotely connected to macroeconomic variables. The economic logic behind these results may be related to the fuel-switching behavior of power producers in influencing primarily carbon futures price changes. (author)

  8. Private capital investments in health care provision through mergers and acquisitions: from long-term to acute care.

    Angeli, Federica; Maarse, Hans

    2016-10-01

    This work aims to test whether different segments of healthcare provision differentially attract private capital and thus offer heterogeneous opportunities for private investors' diversification strategies. Thomson Reuter's SDC Platinum database provided data on 2563 merger and acquisition (M&A) deals targeting healthcare providers in Western Europe between 1990 and 2010. Longitudinal trends of industrial and geographical characteristics of M&As' targets and acquirers are examined. Our analyses highlight: (i) a relative decrease of long-term care facilities as targets of M&As, replaced by an increasing prominence of general hospitals, (ii) a shrinking share of long-term care facilities as targets of financial service organizations' acquisitions, in favor of general hospitals, and (iii) an absolute and relative decrease of long-term care facilities' role as target of cross-border M&As. We explain the decreasing interest of private investors towards long-term care facilities along three lines of reasoning, which take into account the saturation of the long-term care market and the liberalization of acute care provision across Western European countries, regulatory interventions aimed at reducing private ownership to ensure resident outcomes and new cultural developments in favor of small-sized facilities, which strengthen the fragmentation of the sector. These findings advance the literature investigating the effect of private ownership on health outcomes in long-term facilities. Market, policy and cultural forces have emerged over two decades to jointly regulate the presence of privately owned, large-sized long-term care providers, seemingly contributing to safeguard residents' well-being.

    A 2-yr field trial was conducted to assess the impacts of two new transgenic Bt rice lines, T1C-19 expressing Cry1C protein and T2A-1 expressing Cry2A protein, on the arthropod community sampled via vacuum. All the arthropods were classified into five guilds, including herbivores, parasitoids, predators, detritivores, and others. The seasonal density and dominance distribution of each guild and community-level indices (species richness, Shannon-Wiener diversity index, Simpson diversity index, and evenness index) were compared among rice types. Principal response curves were used to investigate the differences of entire arthropod community of Bt rice plots relative to non-Bt rice plots. The results showed no significant difference was detected in the community-level indices and dominance distribution of guilds between Bt and non-Bt rice plots. The seasonal density of herbivores, detritivores, and others as well as density of the arthropod overall community were also not significantly affected by rice types in either year, although the density of predators and parasitoids in Bt rice plots was significantly lower than those in non-Bt rice plots. The lower abundances of Braconidae, Eulophidae, Cyrtorhinus lividipennis (Reuter) (Hemiptera: Miridae), and Theridiidae in Bt rice plots are likely attributed to the lower abundances of prey species or hosts. Principal response curves revealed that arthropod community in Bt was similar with that in non-Bt rice plots. In conclusion, our findings indicate that these two tested Bt rice lines had no marked negative effects on the arthropod community in the paddy fields.

    Full Text Available One of the priorities of the fourth International Polar Year (IPY was to increase awareness of the polar regions and polar science among the general public through education, communication and other forms of outreach. This paper reports on the media coverage of Princess Elisabeth Antarctica (PEA, Belgium's “zero-emission” Antarctic research station designed by the non-profit International Polar Foundation (IPF to run on wind and solar energy and to employ state-of-the-art forms of energy management and other “green” technology. This paper provides background information on PEA, a review of IPF's media strategy for the project, a description of media coverage of the station and a discussion of the way in which the IPF's main messages were reported in the media. IPF staff surveyed approximately 300 media reports released between February 2004, when the PEA project was announced to the general public, and June 2010, when the IPF presented their findings at the IPY conference in Oslo. PEA was featured 580 times in print and web media in Belgium, and 303 times outside Belgium. Major international agencies such as the Associated Press, Agence France Presse, the BBC, Al-Jazeera and Reuters covered the project. On television and radio, PEA was featured in news broadcasts from all four major television networks in Belgium, most major radio stations and 34 different television and radio news outlets outside Belgium. The paper concludes that the media coverage for PEA was significant and suggests reasons why the project was so widely reported.

    A growing burden of gunshot injuries demands evidence-based ballistic trauma management. No comprehensive systematic overview of the current knowledge is available to date. This study aims to identify and analyze the most influential publications in the field of orthopedic ballistic trauma research. All databases available in the Thomson Reuters Web of Knowledge were searched to conduct this bibliometrical study. The most cited orthopedic ballistic trauma articles published between 1950 and 2015 were identified by use of a multi-step approach. Publications with ten citations and more were analyzed for citations, journal, authorship, geographic origin, area of research, anatomical site, study type, study category, and level of evidence. Citations of the 128 included studies ranged from 113 to 10. These were published in fifty different journals between 1953 and 2011. Most publications (n=106; 83%) originated from the USA, were retrospective (n=85; 66.4%), level IV studies (n=90; 70.3%), reported on spinal gunshot injuries (n=49; 38.33%) and were published between 1980 and 2000 (n=111; 86.7%). This bibliometric study provides the first comprehensive overview of influential publications in the field of orthopedic ballistic trauma research. More prospective studies and high-quality systematic reviews are needed. Centres with a high burden of gunshot injuries from the developing world need to share their experience in form of international publications, to provide a more comprehensive picture of the global gun-related orthopedic injury burden. bibliometric analysis: level III.

    To assess the evidence for risk factors and prevention measures for shoulder injuries in overhead sports. Systematic review with best-evidence synthesis. Medline (Ovid), PubMed (complementary search), Embase (Elsevier), Cochrane (Wiley), SPORTDiscus (Ebsco) and Web of Science Core Collection (Thomson Reuters), from 1 January 1990 to 15 May 2017. Randomised controlled trials, cohort studies and case-control studies on risk factors or prevention measures for shoulder injuries in overhead sports. The eligible studies were quality assessed using the Scottish Intercollegiate Guidelines Network criteria. Of 4778 studies identified, 38 were eligible for quality review and 17 met the quality criteria to be included in the evidence synthesis. One additional quality study presented a shoulder injury prevention programme. Most studies focused on baseball, lacrosse or volleyball (n=13). The risk factors examined included participation level (competition vs training) (n=10), sex (n=4), biomechanics (n=2) and external workload (n=2). The evidence for all risk factors was limited or conflicting. The effect of the prevention programme within the subgroup of uninjured players at baseline was modest and possibly lacked statistical power. All investigated potential risk factors for shoulder injury in overhead sports had limited evidence, and most were non-modifiable (eg, sex). There is also limited evidence for the effect of shoulder injury prevention measures in overhead sports.

    Full Text Available Pediatric tuberculosis (TB is known to have a wide range of presentations, and if left untreated, primary TB may lead to bone and joint involvement. The literature on this topic is very scarce, and no comprehensive systematic review or meta-analysis of the current knowledge is available to date. The aim of this study is to identify and analyze the literature with highest impact based on citation rate analysis. All databases of the Thomson and Reuters “Web of Knowledge” were used to conduct our search of the 100 most cited articles on this topic published between 1950 and 2014. The included articles were analyzed in terms of citation rate, age, study type, area of research, level of evidence (LOE, and more. All 100 articles were published between 1967 and 2011 in 51 different journals. The average citation rate was 74.26, all articles were on average 23.1 years, and most studies were originated from India (n = 22, followed by the USA (n = 21. The majority of publications were review articles (42%, described clinical course (n = 48, and assigned an LOE IV (44%. TB infection is a high burden disease in low-income countries but widely studied in a fi rst world setup. This research gap between the geographic distribution of disease burden and origin of publications could initiate possibilities for high-burden countries to share their opinion. Their experience is of a high level of importance and relevance which furthermore is necessary to create a more accurate picture of pediatric musculoskeletal TB burden in literature.

  14. The emergence and evolution of the research fronts in HIV/AIDS research.

    Full Text Available In this paper, we have identified and analyzed the emergence, structure and dynamics of the paradigmatic research fronts that established the fundamentals of the biomedical knowledge on HIV/AIDS. A search of papers with the identifiers "HIV/AIDS", "Human Immunodeficiency Virus", "HIV-1" and "Acquired Immunodeficiency Syndrome" in the Web of Science (Thomson Reuters, was carried out. A citation network of those papers was constructed. Then, a sub-network of the papers with the highest number of inter-citations (with a minimal in-degree of 28 was selected to perform a combination of network clustering and text mining to identify the paradigmatic research fronts and analyze their dynamics. Thirteen research fronts were identified in this sub-network. The biggest and oldest front is related to the clinical knowledge on the disease in the patient. Nine of the fronts are related to the study of specific molecular structures and mechanisms and two of these fronts are related to the development of drugs. The rest of the fronts are related to the study of the disease at the cellular level. Interestingly, the emergence of these fronts occurred in successive "waves" over the time which suggest a transition in the paradigmatic focus. The emergence and evolution of the biomedical fronts in HIV/AIDS research is explained not just by the partition of the problem in elements and interactions leading to increasingly specialized communities, but also by changes in the technological context of this health problem and the dramatic changes in the epidemiological reality of HIV/AIDS that occurred between 1993 and 1995.

    The aim of this systematic review was to summarize and systematize the information about physical symptoms and its relation with work activity on female Breast Cancer Survivors (BCS). A systematic search was performed on the databases MEDLINE/PubMed (via National Library of Medicine), SCOPUS (Elsevier), Web of Science (Thomson Reuters Scientific) and CINAHL with full text (EBSCO), including papers about physical impairments experienced by female workers who have had breast cancer. The search retrieved 238 studies, and another 5 were identified in the articles' references, totaling 243 papers. After removing duplicates and applying the inclusion criteria and a full text reading, 13 articles were included for qualitative analysis. Concerning physical limitations, most complaints were related to the elevation of upper limbs, carrying heavy objects, driving and holding manual movements. The most referred symptoms were breast/arm pain, fatigue, lymphedema, reduced range of motion and weakness in the upper limbs, scar tissue adherence in the breast/axilla and paresthesia in the arm/breast. These symptoms and physical limitations led to the difficulty or impossibility of performing work tasks, which also diminished work productivity, as well as the increase in time to return to work. The present results suggest higher unemployment rates and the need for modifying work conditions. Implication for Rehabilitation Health professionals should include risk assessment at daily routine to identify possible sources of physical impairments for upper limbs. Provide the support and orientations according to personal and job characteristics of the patient. Focus the aims of treatment over upper limbs impairments, reducing the prevalence and the gravity of symptoms.

    Although there has been a continuous increase in the number of women working in the field of medicine, women rarely reach the highest academic positions as full professors or editorial board members. We aimed to determine the proportion of women on the editorial boards of top-ranked medical journals in different medical specialties. We analyzed the gender of editorial board members of 60 top-ranked journals of 12 Thomson Reuters Web of Knowledge Journal Citation Reports categories. A total of 4175 editors were included in our analysis. Only 15.9% (10 of 63) editors-in-chief were female. In the 5 categories, critical care, anesthesiology, orthopedics, ophthalmology and radiology, nuclear medicine and medical imaging, currently not 1 woman holds the position of editor-in-chief. Less than one fifth (17.5%, 719 of 4112) of all editorial board members were women. There were significant differences among the evaluated categories, with the highest percentage of women in the category of medicine, general and internal and the lowest in the category critical care, followed by orthopedics. In every category, the proportion of women as editorial board members was substantially lower than that of men. Women are underrepresented on the editorial boards of major medical journals, although there is a great variability among the journals and categories analyzed. If more women are nominated to serve on editorial boards, they will be a visible sign of continuing progress and serve as important role models for young women contemplating a career in academic medicine.

    A survey of journals published in the field of Gastroenterology conducted 5 years ago showed marked variability in reporting of conflicts of interest or funding sources in these journals. To re-examine reporting of conflicts of interest and funding sources for original articles and editorials in Gastroenterology and Hepatology journals. We evaluated all original articles and editorials in 15 leading journals (determined by impact factor-Thomson Reuter Science Citation Index) devoted to Gastroenterology and Hepatology for disclosures of conflicts and for editor's self disclosures. We examined each journal's editorial policy by contacting the journal directly if the information was not revealed on the Web site or print versions of the journal. Of the 1574 articles evaluated, a total of 1207 (77%) reported the presence or absence of a potential conflict of interest and 1047 (67%) reported the presence or absence of funding sources. A total of 3 of the 15 (20%) journals (American Journal of Gastroenterology, Gastroenterology, and Alimentary Pharmacology and Therapeutics reported the presence or absence of funding sources in all their published original articles. Only 5 of 15 (33%) journals (Gut, Gastrointestinal Endoscopy, American Journal of Gastroenterology, Neurogastroenterology & Motility and Alimentary Pharmacology and Therapeutics) publicly disclosed the conflicts of interest of the editors. (i) Funding sources and conflicts of interest are still reported variably in the GI literature. (ii) Editorials and review articles are influential, but have poor reporting of conflicts of interest. (iii) Editors of many journals still do not report their conflicts of interest. © 2012 Blackwell Publishing Ltd.

    2008-07-01

    Random matrix theory (RMT) filters, applied to covariance matrices of financial returns, have recently been shown to offer improvements to the optimisation of stock portfolios. This paper studies the effect of three RMT filters on the realised portfolio risk, and on the stability of the filtered covariance matrix, using bootstrap analysis and out-of-sample testing. We propose an extension to an existing RMT filter, (based on Krzanowski stability), which is observed to reduce risk and increase stability, when compared to other RMT filters tested. We also study a scheme for filtering the covariance matrix directly, as opposed to the standard method of filtering correlation, where the latter is found to lower the realised risk, on average, by up to 6.7%. We consider both equally and exponentially weighted covariance matrices in our analysis, and observe that the overall best method out-of-sample was that of the exponentially weighted covariance, with our Krzanowski stability-based filter applied to the correlation matrix. We also find that the optimal out-of-sample decay factors, for both filtered and unfiltered forecasts, were higher than those suggested by Riskmetrics [J.P. Morgan, Reuters, Riskmetrics technical document, Technical Report, 1996. http://www.riskmetrics.com/techdoc.html], with those for the latter approaching a value of α=1. In conclusion, RMT filtering reduced the realised risk, on average, and in the majority of cases when tested out-of-sample, but increased the realised risk on a marked number of individual days-in some cases more than doubling it.

    Bibliometric analysis highlights the key topics and publications, which have shaped surgical education. Here, the 100 most cited articles in the arena of surgical education were analyzed. Thomson Reuters Web of Science was interrogated using the keyword search terms "surgery" and ("learning" or "skills" or "competence" or "assessment" or "training" or "procedure-based assessments" or "performance" or "technical skills" or "curriculum" or "education" or "mentoring"] to identify all English language full articles, and the 100 most cited articles were analyzed by topic, journal, author, year, institution, and country of origin. A total of 403,733 eligible articles were returned and the median citation number was 164 (range: 107-1018). The most cited article (by Seymour, Yale University School of Medicine, Annals of Surgery, 1018 citations) focused on the use of virtual reality surgical simulation training. Annals of Surgery published the highest number of articles and received the most citations (n = 16, 3715 citations). The countries with the greatest number of publications were the USA (n = 45), Canada (n = 19), and the UK (n = 18). The commonest topics included simulation (n = 45) and assessment of clinical competence (n = 40). Surgical skill acquisition and assessment was the area of focus of 85% of the most cited contemporary articles, and this study provides the most cited references, serving as a guide as to what makes a citable published work in the field of surgical education.

    2016-10-01

    To systematically analyze the effects of direct-to-consumer advertising (DTCA) on patient requests for medication and physician prescribing across psychiatry-relevant studies. MEDLINE, PsycINFO, Thomson Reuters' ISI Web of Knowledge, and Google Scholar were searched (1999-2014) using variations of the terms direct-to-consumer advertising and psychiatric. Reference lists and an online repository of DTCA manuscripts were also scrutinized. English-language studies collecting data at the point of service, focusing on or including psychiatric medication, and assessing the effects of DTCA on patient and/or physician behavior were included. Of 989 articles identified, 69 received full-text review. Four studies across 5 manuscripts met inclusion criteria. Data were extracted on participants, study design, methodological quality, and results. Methodological quality of individual studies was assessed using adapted criteria from the Effective Public Health Practice Project. Confidence in conclusions across studies was determined using principles from the well-established GRADE system. Due to lack of replication across strong randomized controlled trials (RCTs), no conclusions merited high confidence. With moderate confidence, we concluded that DTCA requests (1) are granted most of the time (1 RCT, 3 observational), (2) prompt higher prescribing volume (1 RCT, 1 observational), (3) promote greater adherence to minimally acceptable treatment guidelines for patients with depression (1 RCT), and (4) stimulate overprescribing among patients with an adjustment disorder (1 RCT). Findings suggest that DTCA requests are typically accommodated, promote higher prescribing volume, and have competing effects on treatment quality. More methodologically strong studies are needed to increase confidence in conclusions. © Copyright 2016 Physicians Postgraduate Press, Inc.

    Understanding the mutual relationships between information flows and social activity in society today is one of the cornerstones of the social sciences. In financial economics, the key issue in this regard is understanding and quantifying how news of all possible types (geopolitical, environmental, social, financial, economic, etc.) affects trading and the pricing of firms in organized stock markets. In this article, we seek to address this issue by performing an analysis of more than 24 million news records provided by Thompson Reuters and of their relationship with trading activity for 206 major stocks in the S&P US stock index. We show that the whole landscape of news that affects stock price movements can be automatically summarized via simple regularized regressions between trading activity and news information pieces decomposed, with the help of simple topic modeling techniques, into their “thematic” features. Using these methods, we are able to estimate and quantify the impacts of news on trading. We introduce network-based visualization techniques to represent the whole landscape of news information associated with a basket of stocks. The examination of the words that are representative of the topic distributions confirms that our method is able to extract the significant pieces of information influencing the stock market. Our results show that one of the most puzzling stylized facts in financial economies, namely that at certain times trading volumes appear to be “abnormally large,” can be partially explained by the flow of news. In this sense, our results prove that there is no “excess trading,” when restricting to times when news is genuinely novel and provides relevant financial information. PMID:23762258

    Air samples from twelve sampling sites (including seven intra-plant sites, one upwind site and four downwind sites) from a wastewater treatment plant (WWTP) in Beijing were collected using a Reuter Centrifugal Sampler High Flow (RCS); and their microbial fractions were studied using culturing and high throughput gene sequence. In addition, the viable (fluorescent) bioaerosol concentrations for 7 intra-plant sites were also monitored for 30 min each using an ultraviolet aerodynamic particle sizer (UV-APS). Both air and water samples collected from the plant were investigated for possible bacterial antibiotic resistance genes and integrons using polymerase chain reaction (PCR) coupled with gel electrophoresis. The results showed that the air near sludge thickening basin was detected to have the highest level of culturable bacterial aerosols (up to 1697 CFU/m3) and fungal aerosols (up to 930 CFU/m3). For most sampling sites, fluorescent peaks were observed at around 3-4 μm, except the office building with a peak at 1.5 μm, with a number concentration level up to 1233-6533 Particles/m3. About 300 unique bacterial species, including human opportunistic pathogens, such as Comamonas Testosteroni and Moraxella Osloensis, were detected from the air samples collected over the biological reaction basin. In addition, we have detected the sul2 gene resistant to cotrimoxazole (also known as septra, bactrim and TMP-SMX) and class 1 integrase gene from the air samples collected from the screen room and the biological reaction basin. Overall, the screen room, sludge thickening basin and biological reaction basin imposed significant microbial exposure risks, including those from airborne antibiotic resistance genes.

    We previously demonstrated absence of association between peer-review-derived percentile ranking and raw citation impact in a large cohort of National Heart, Lung, and Blood Institute cardiovascular R01 grants, but we did not consider pregrant investigator publication productivity. We also did not normalize citation counts for scientific field, type of article, and year of publication. To determine whether measures of investigator prior productivity predict a grant's subsequent scientific impact as measured by normalized citation metrics. We identified 1492 investigator-initiated de novo National Heart, Lung, and Blood Institute R01 grant applications funded between 2001 and 2008 and linked the publications from these grants to their InCites (Thompson Reuters) citation record. InCites provides a normalized citation count for each publication stratifying by year of publication, type of publication, and field of science. The coprimary end points for this analysis were the normalized citation impact per million dollars allocated and the number of publications per grant that has normalized citation rate in the top decile per million dollars allocated (top 10% articles). Prior productivity measures included the number of National Heart, Lung, and Blood Institute-supported publications each principal investigator published in the 5 years before grant review and the corresponding prior normalized citation impact score. After accounting for potential confounders, there was no association between peer-review percentile ranking and bibliometric end points (all adjusted P>0.5). However, prior productivity was predictive (Pcitation counts, we confirmed a lack of association between peer-review grant percentile ranking and grant citation impact. However, prior investigator publication productivity was predictive of grant-specific citation impact. © 2014 American Heart Association, Inc.

    Spinal deformity is a condition that has been recognized for many millennia. There have been major advances in the treatment of spinal deformity in recent years and studies outlining new ideas can inspire others to further advance the speciality. The number of citations a paper receives may indicate the influence of that paper. It is therefore important that we evaluate and analyze the most cited works in our field. The aim of this study is to identify the 100 most cited papers relevant to spinal deformity surgery in the literature. A search through the Thomson Reuters Web of Science™ for citations related to spinal deformity surgery was performed. The number of citations, mean citation number (total number citations/years since publication), journal, authors, year of publication and country of origin of the top 100 papers was recorded. The top 100 papers were cited a combined 17,646 times, ranging from 453 to 112. The majority of papers originated from the United States (71) and were published in 20 different journals. The decade 1990-1999 was the most prolific, with 36 of the 100 papers published during this time. Papers pertaining to the management of scoliosis (49) were the most common. This study identifies the top 100 most cited papers in the field of spinal deformity surgery. While citation is not a specific marker of the scientific quality of a paper, it is a surrogate for the influence a paper has had on the orthopedic community. This list of papers provides an invaluable resource for both those in training and those actively practicing and involved in the further development of spinal deformity surgery.

    Chordomas are rare malignant primary tumors of the spine. In the mobile spine and sacrum an en-bloc resection is associated with decreased rates of recurrence. Our objective was to identify the top cited articles in chordoma research and to further analyze characteristics of these articles. In March 2017, we used ISI Web of Science (v5.11, Thomas Reuter, Philadelphia, Pennsylvania, USA) to search for the following key word: "chordoma". Articles were searched from 1900 to 2017. Articles were ranked based on number of citations. The results were evaluated to determine articles most clinically relevant to the management of chordomas. The top 50 articles that met the search criteria were further characterized on the basis of: title, author, citation density, journal of publication, year (and decade) of publication, institution and country of origin and paper topic. A total of 1,043 articles matched the search criteria. The most influential 50 articles were cited 65 to 290 times. The articles were published between 1926 and 2012, and all articles were published in English. Thirty-three publications (66%) originated from the United States and seven (14%) from Italy. Cancer accounted for the most frequent (n=9) destination journal followed by Journal of Bone and Joint Surgery (n=4). A total of 41 institutions contributed to the top 50 articles. The most common article types were: clinical 44% (n=22), papers that combined clinical and pathology findings 18% (n=9) and basic science research 14% (n=7). The top 50 cited articles on chordomas are predominantly clinical papers, arising from the United States and most frequently published in Cancer and Journal of Bone and Joint Surgery .

    The status of citations can reflect the impact of a paper and its contribution to surgical practice. The aim of our study was to identify and review the 100 most-cited papers in general thoracic surgery. Relevant papers on general thoracic surgery were searched through Thomson Reuters Web of Science in the last week of November 2017. Results were returned in descending order of total citations. Their titles and abstracts were reviewed to identify whether they met our inclusion criteria by two thoracic surgeons independently. Characteristics of the first 100 papers, including title, journal name, country, first author, year of publication, total citations, citations in latest 5 years and average citation per year (ACY) were extracted and analyzed. Of the 100 papers, the mean number of citations was 322 with a range from 184 to 921. 19 journals published the papers from 1956 to 2012. Annals of Surgery had the largest number (29), followed by Journal of Thoracic and Cardiovascular Surgery (22) and Annals of Thoracic Surgery (21). The majority of the papers were published in 2000s (48) and originated from United States of America (62). There were 65 retrospective studies, 13 RCTs and 11 prospective studies. Orringer MB and Grillo HC contributed 4 first-author articles respectively. There were 53 papers on esophagus, 36 on lung, 6 on pleura and 5 on trachea. Our study identified the most-cited papers in the past several decades and offered insights into the development and advances of general thoracic surgery. It can help us understand the evidential basis of clinical decision-making today in the area. Copyright © 2018. Published by Elsevier Ltd.

    Full Text Available International collaborative research is a mechanism for improving the development of disease-specific therapies and for improving health at the population level. However, limited data are available to assess the trends in research output related to orphan diseases.We used bibliometric mapping and clustering methods to illustrate the level of fragmentation in myeloma research and the development of collaborative efforts. Publication data from Thomson Reuters Web of Science were retrieved for 2005-2009 and followed until 2013. We created a database of multiple myeloma publications, and we analysed impact and co-authorship density to identify scientific collaborations, developments, and international key players over time. The global annual publication volume for studies on multiple myeloma increased from 1,144 in 2005 to 1,628 in 2009, which represents a 43% increase. This increase is high compared to the 24% and 14% increases observed for lymphoma and leukaemia. The major proportion (>90% of publications was from the US and EU over the study period. The output and impact in terms of citations, identified several successful groups with a large number of intra-cluster collaborations in the US and EU. The US-based myeloma clusters clearly stand out as the most productive and highly cited, and the European Myeloma Network members exhibited a doubling of collaborative publications from 2005 to 2009, still increasing up to 2013.Multiple myeloma research output has increased substantially in the past decade. The fragmented European myeloma research activities based on national or regional groups are progressing, but they require a broad range of targeted research investments to improve multiple myeloma health care.

    Full Text Available AIM: To identify the 100 most cited papers in cataract surgery, we performed a comprehensive bibliometric analysis basing on the literature search on the Thomson Reuters Web of Knowledge. METHODS: The number of citations, including the total citations, latest 5y citations and average citation number per year (ACY, authorship, year of publication, major topics, journal of publication, country and institution of origin of each paper were recorded and then analyzed. Pearson’s correlation analysis was conducted to evaluate the correlation between the published year and the number of citations. The correlation between journal’s impact factor (IF and number of citations was assessed as well. RESULTS: The most cited paper was the classic paper done by the European Society of Cataract & Refractive Surgeons (ESCRS group. This paper focused on the topic of endophthalmitis. Not only the most cited papers originated from the USA, but also some American institutions like Johns Hopkins University, Harvard Medical School, etc. had the most citations. Pearson’s correlation analysis indicated that the latest 5y citations and ACY were significantly related with the published year (5y citations: r=0.615, P<0.001; ACY: r=0.657, P<0.001, whereas no association between the total number of citations and published year was found (r=0.045. Moreover, the IFs of journals were found to have no significant effect on the number of total citations. CONCLUSION: To our knowledge, this is the first study on the most influential papers in cataract surgery after a comprehensive research of relevant literatures. The present work may provide us concise information concerning the development history of cataract surgery over the past 66y.

    The open access paradigm has become an important approach in today's information and communication society. Funders and governments in different countries stipulate open access publications of funded research results. Medical informatics as part of the science, technology and medicine disciplines benefits from many research funds, such as National Institutes of Health in the US, Wellcome Trust in UK, German Research Foundation in Germany and many more. In this study an overview of the current open access programs and conditions of major journals in the field of medical informatics is presented. It was investigated whether there are suitable options and how they are shaped. Therefore all journals in Thomson Reuters Web of Science that were listed in the subject category "Medical Informatics" in 2014 were examined. An Internet research was conducted by investigating the journals' websites. It was reviewed whether journals offer an open access option with a subsequent check of conditions as for example the type of open access, the fees and the licensing. As a result all journals in the field of medical informatics that had an impact factor in 2014 offer an open access option. A predominantly consistent pricing range was determined with an average fee of 2.248 € and a median fee of 2.207 €. The height of a journals' open access fee did not correlate with the height of its Impact Factor. Hence, medical informatics journals have recognized the trend of open access publishing, though the vast majority of them are working with the hybrid method. Hybrid open access may however lead to problems in questions of double dipping and the often stipulated gold open access.

    Twitter is an increasingly popular means of research dissemination. I sought to examine the relation between scientific merit and mainstream popularity of general medical journals. I extracted impact factors and citations for 2014 for all general medical journals listed in the Thomson Reuters InCites Journal Citation Reports. I collected Twitter statistics (number of followers, number following, number of tweets) between July 25 and 27, 2015 from the Twitter profiles of journals that had Twitter accounts. I calculated the ratio of observed to expected Twitter followers according to citations via the Kardashian Index. I created the (Fifty Shades of) Grey Scale to calculate the analogous ratio according to impact factor. Only 28% (43/153) of journals had Twitter profiles. The scientific and social media impact of journals were correlated: in adjusted models, Twitter followers increased by 0.78% (95% confidence interval [CI] 0.38%-1.18%) for every 1% increase in impact factor and by 0.62% (95% CI 0.34%-0.90%) for every 1% increase in citations. Kardashian Index scores above the 99% CI were obsverved in 16% (7/43) of journals, including 6 of the 7 highest ranked journals by impact factor, whereas 58% (25/43) had scores below this interval. For the Grey Scale, 12% (5/43) of journals had scores above and 35% (15/43) had scores below the 99% CI. The size of a general medical journal's Twitter following is strongly linked to its impact factor and citations, suggesting that higher quality research received more mainstream attention. Many journals have not capitalized on this dissemination method, although others have used it to their advantage. © 2015 Canadian Medical Association or its licensors.

  12. RWE Gas looking for ways of gaining influence in Nafta

    German gas company RWE Gas considers the possibility of transferring its 40-percent stake in Nafta, a.s., Gbely to its Czech daughter-company Transgas. According to Reuters RWE's main incentive for this transaction was to increase its stake in the Czech company to 97 percent. That would reduce some minority shareholder rights linked to the remaining shares held by the Czech government and reduce the price of the minority stake. Czech National Property Fund plans to sell the state-owned less then 3-percent stake in a tender for about 3 billion Czech crowns RWE Gas (after it puts its Nafta stake into Transgas) only considers to pay one third of this amount. The primary motivations to start considerations about joining in with Transgas were improved business relationship with Nafta and a possibility to better co-ordinate storage of gas in the region. Transgas is not only the largest gas-distribution company in Czech Republic and the owner of most of the county's storage capacities, it has contracts for storage of 500 million cubic metres a year in Slovakia. And these are the links RWE Gas wants to take advantage of. RWE itself was not in the position to supply gas into Nafta's gas reservoirs and so meet the conditions of Memorandum of Mutual Agreement signed before it entered the Slovak company. This memorandum was signed in 2000 with owner of a 56-percent stake in Nafta - Slovensky plynarensky priemysel (SPP), a.s., Bratislava. The fact that RWE could not meet this condition hindered it form taking an active part in Nafta's management. (Author)

    Bibliometric tools can be used to identify the authors, topics and research institutions that have made the greatest impact in a field of medicine. The aim of this research was to analyse military trauma publications over the last 16 years of armed conflict in order to highlight the most important lessons that have translated into civilian practice and military doctrine as well as identify emerging areas of importance. A systematic search of research published between January 2000 and December 2016 was conducted using the Thompson Reuters Web of Science database. Both primary evidence and review publications were included. Results were categorised according to relevance and topic and the 30 most cited publications were reviewed in full. The h-index, impact factors, citation counts and citation analysis were used to evaluate results. A plateau in the number of annual publications on military trauma was found, as was a shift away from publications on wound and mortality epidemiology to publications on traumatic brain injury (TBI), neurosurgery or blast injury to the head. Extensive collaboration networks exist between highly contributing authors and institutions, but less collaboration between authors from different countries. The USA produced the majority of recent publications, followed by the UK, Germany and Israel. In recent years, the number of publications on TBI, neurosurgery or blast injury to the head has increased. It is likely that the lessons of recent conflicts will continue to influence civilian medical practice, particularly regarding the long-term effects of blast-related TBI. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

This study examined associations between rock climbing and acute emotion regulating effects in patients with major depression. Patients and methods: In a nonrandomized, controlled study, 40 major depressive disorder inpatients were assigned to either a climbing session (n=20 or a relaxation session (n=20. Positive and negative affect, depressiveness, and coping emotions were assessed immediately before and after the session. Results: Mixed analyses of variance and covariance revealed significant time × group interaction effects for all assessed outcomes (p≤0.012: positive affect and coping emotions significantly increased and negative affect and depressiveness significantly decreased after the climbing session (1.04≤ Cohen’s d ≤1.30, in contrast to a relaxation session (0.16≤ Cohen’s d ≤0.36. Conclusion: The results show that rock climbing is associated with acute emotion regulatory effects. These findings have to be replicated with a randomized design, and future research should pay attention to possible mechanisms of rock climbing in regard to emotion regulation.

    Adipose tissue, which can be readily harvested via a number of liposuction techniques, offers an easily accessible and abundant source of adipose-derived stem cells (ASCs). Consequently, ASCs have become an increasingly popular reconstructive option and a novel means of aesthetic soft tissue augmentation. This paper examines recent advances in the aesthetic surgery field, extending beyond traditional review formats to incorporate a comprehensive analysis of current clinical trials, adoption status, and the commercialization pathway. Keyword searches were carried out on clinical trial databases to search for trials using ASCs for aesthetic indications. An intellectual property landscape was created using commercial software (Thomson Reuters Thomson Innovation, New York, NY). Analysis of who is claiming what in respect of ASC use in aesthetic surgery for commercial purposes was analyzed by reviewing the patent landscape in relation to these techniques. Key international regulatory guidelines were also summarized. Completed clinical trials lacked robust controls, employed small sample sizes, and lacked long-term follow-up data. Ongoing clinical trials still do not address such issues. In recent years, claims to intellectual property ownership have increased in the "aesthetic stem cell" domain, reflecting commercial interest in the area. However, significant translational barriers remain including regulatory challenges and ethical considerations. Further rigorous randomized controlled trials are required to delineate long-term clinical efficacy and safety. Providers should consider the introduction of patient reported outcome metrics to facilitate clinical adoption. Robust regulatory and ethical policies concerning stem cells and aesthetic surgery should be devised to discourage further growth of "stem cell tourism." © 2017 The American Society for Aesthetic Plastic Surgery, Inc.

    Full Text Available Spinal deformity is a condition that has been recognized for many millennia. There have been major advances in the treatment of spinal deformity in recent years and studies outlining new ideas can inspire others to further advance the speciality. The number of citations a paper receives may indicate the influence of that paper. It is therefore important that we evaluate and analyze the most cited works in our field. The aim of this study is to identify the 100 most cited papers relevant to spinal deformity surgery in the literature. A search through the Thomson Reuters Web of ScienceTM for citations related to spinal deformity surgery was performed. The number of citations, mean citation number (total number citations/years since publication, journal, authors, year of publication and country of origin of the top 100 papers was recorded. The top 100 papers were cited a combined 17,646 times, ranging from 453 to 112. The majority of papers originated from the United States (71 and were published in 20 different journals. The decade 1990-1999 was the most prolific, with 36 of the 100 papers published during this time. Papers pertaining to the management of scoliosis (49 were the most common. This study identifies the top 100 most cited papers in the field of spinal deformity surgery. While citation is not a specific marker of the scientific quality of a paper, it is a surrogate for the influence a paper has had on the orthopedic community. This list of papers provides an invaluable resource for both those in training and those actively practicing and involved in the further development of spinal deformity surgery.

  17. High quality topic extraction from business news explains abnormal financial market volatility.

    Directory of Open Access Journals (Sweden)

    Ryohei Hisano

    Full Text Available Understanding the mutual relationships between information flows and social activity in society today is one of the cornerstones of the social sciences. In financial economics, the key issue in this regard is understanding and quantifying how news of all possible types (geopolitical, environmental, social, financial, economic, etc. affects trading and the pricing of firms in organized stock markets. In this article, we seek to address this issue by performing an analysis of more than 24 million news records provided by Thompson Reuters and of their relationship with trading activity for 206 major stocks in the S&P US stock index. We show that the whole landscape of news that affects stock price movements can be automatically summarized via simple regularized regressions between trading activity and news information pieces decomposed, with the help of simple topic modeling techniques, into their "thematic" features. Using these methods, we are able to estimate and quantify the impacts of news on trading. We introduce network-based visualization techniques to represent the whole landscape of news information associated with a basket of stocks. The examination of the words that are representative of the topic distributions confirms that our method is able to extract the significant pieces of information influencing the stock market. Our results show that one of the most puzzling stylized facts in financial economies, namely that at certain times trading volumes appear to be "abnormally large," can be partially explained by the flow of news. In this sense, our results prove that there is no "excess trading," when restricting to times when news is genuinely novel and provides relevant financial information.

    Phenolic compounds are of crucial importance for red wine color and mouthfeel attributes. A large number of enzymatic and chemical reactions involving phenolic compounds take place during winemaking and aging. Despite the large number of published analytical methods for phenolic analyses, the values obtained may vary considerably. In addition, the existing scientific knowledge needs to be updated, but also critically evaluated and simplified for newcomers and wine industry partners. The most used and widely cited spectrophotometric methods for grape and wine phenolic analysis were identified through a bibliometric search using the Science Citation Index-Expanded (SCIE) database accessed through the Web of Science (WOS) platform from Thompson Reuters. The selection of spectrophotometry was based on its ease of use as a routine analytical technique. On the basis of the number of citations, as well as the advantages and disadvantages reported, the modified Somers assay appears as a multistep, simple, and robust procedure that provides a good estimation of the state of the anthocyanins equilibria. Precipitation methods for total tannin levels have also been identified as preferred protocols for these types of compounds. Good reported correlations between methods (methylcellulose precipitable vs bovine serum albumin) and between these and perceived red wine astringency, in combination with the adaptation to high-throughput format, make them suitable for routine analysis. The bovine serum albumin tannin assay also allows for the estimation of the anthocyanins content with the measurement of small and large polymeric pigments. Finally, the measurement of wine color using the CIELab space approach is also suggested as the protocol of choice as it provides good insight into the wine's color properties.

    Evidence-based medicine works best if the evidence is reported well. Past studies have shown reporting quality to be lacking in the field of surgery. Reporting guidelines are an important tool for authors to optimize the reporting of their research. The objective of this study was to analyse the frequency and strength of recommendation for such reporting guidelines within surgical journals. A systematic review of the 198 journals within the Journal Citation Report 2014 (surgery category) published by Thomson Reuters was undertaken. The online guide for authors for each journal was screened by two independent groups and results compared. Data regarding the presence and strength of recommendation to use reporting guidelines was extracted. 193 journals were included (as five appeared twice having changed their name). These had a median impact factor of 1.526 (range 0.047-8.327), with a median of 145 articles published per journal (range 29-659), with 34,036 articles published in total over the two-year window 2012-2013. The majority (62%) of surgical journals made no mention of reporting guidelines within their guidelines for authors. Of the 73 (38%) that did mention them, only 14% (10/73) required the use of all relevant reporting guidelines. The most frequently mentioned reporting guideline was CONSORT (46 journals). The mention of reporting guidelines within the guide for authors of surgical journals needs improvement. Authors, reviewers and editors should work to ensure that research is reported in line with the relevant reporting guidelines. Journals should consider hard-wiring adherence to them.

    Background In times of globalization there is an increasing use of English in the medical literature. The aim of this study was to analyze the influence of English-language articles in multi-language medical journals on their international recognition – as measured by a lower rate of self-citations and higher impact factor (IF). Methods and Findings We analyzed publications in multi-language journals in 2008 and 2009 using the Web of Science (WoS) of Thomson Reuters (former Institute of Scientific Information) and PubMed as sources of information. The proportion of English-language articles during the period was compared with both the share of self-citations in the year 2010 and the IF with and without self-citations. Multivariable linear regression analysis was performed to analyze these factors as well as the influence of the journals‘ countries of origin and of the other language(s) used in publications besides English. We identified 168 multi-language journals that were listed in WoS as well as in PubMed and met our criteria. We found a significant positive correlation of the share of English articles in 2008 and 2009 with the IF calculated without self-citations (Pearson r=0.56, p = journal‘s country of origin – North American journals had a higher IF compared to Middle and South American or European journals. Conclusion Our findings suggest that a larger share of English articles in multi-language medical journals is associated with greater international recognition. Fewer self-citations were found in multi-language journals with a greater share of original articles in English. PMID:24146929

    The purpose of this study was to develop a method to simulate the cardiac action potential using a Microsoft Excel spreadsheet. The mathematical model contained voltage-gated ionic currents that were modeled using either Beeler-Reuter (B-R) or Luo-Rudy (L-R) phase 1 kinetics. The simulation protocol involves the use of in-cell formulas directly typed into a spreadsheet. The capability of spreadsheet iteration was used in these simulations. It does not require any prior knowledge of computer programming, although the use of the macro language can speed up the calculation. The normal configuration of the cardiac ventricular action potential can be well simulated in the B-R model that is defined by four individual ionic currents, each representing the diffusion of ions through channels in the membrane. The contribution of Na+ inward current to the rate of depolarization is reproduced in this model. After removal of Na+ current from the model, a constant current stimulus elicits an oscillatory change in membrane potential. In the L-R phase 1 model where six types of ionic currents were defined, the effect of extracellular K+ concentration on changes both in the time course of repolarization and in the time-independent K+ current can be demonstrated, when the solutions are implemented in Excel. Using the simulation protocols described here, the users can readily study and graphically display the underlying properties of ionic currents to see how changes in these properties determine the behavior of the heart cell. The method employed in these simulation protocols may also be extended or modified to other biological simulation programs.

    As a result of the various telemedicine projects in the past years a large number of studies were recently published in this field. However, a precise bibliometric analysis of telemedicine publications does not exist so far. The present study was conducted to establish a data base of the existing approaches. Density-equalizing algorithms were used and data was retrieved from the Thomson Reuters database Web of Science. During the period from 1900 to 2006 a number of 3290 filed items were connected to telemedicine, with the first being published in 1964. The studies originate from 101 countries, with the USA, Great Britain and Canada being the most productive suppliers participating in 56.08 % of all published items. Analyzing the average citation per item for countries with more than 10 publications, Ireland ranked first (10.19/item), New Zealand ranked second (9.5/item) followed by Finland (9.04/item). The citation rate can be assumed as an indicator for research quality. The ten most productive journals include three journals with the main focus telemedicine and another five with the main focus "Information/Informatics". In all subject categories examined for published items related to telemedicine, "Health Care Sciences & Services" ranked first by far. More than 36 % of all publications are assigned to this category, followed by "Medical Informatics" with 9.72 % and "Medicine, General & Internal" with 8.84 % of all publications. In summary it can be concluded that the data shows clearly a strong increase in research productivity. Using science citation analysis it can be assumed that there is a large rise in the interest in telemedicine studies.

    The number of citations that a research paper receives can be used as a measure of its scientific impact. The objective of this study was to identify and to examine the characteristics of top 100 cited articles in the field of Medical Informatics based on data acquired from the Thomson Reuters' Web of Science (WOS) in October, 2016. The data was collected using two procedures: first we included articles published in the 24 journals listed in the "Medical Informatics" category; second, we retrieved articles using the key words: "informatics", "medical informatics", "biomedical informatics", "clinical informatics" and "health informatics". After removing duplicate records, articles were ranked by the number of citations they received. When the 100 top cited articles had been identified, we collected the following information for each record: all WOS database citations, year of publication, journal, author names, authors' affiliation, country of origin and topics indexed for each record. Citations for the top 100 articles ranged from 346 to 7875, and citations per year ranged from 11.12 to 525. The majority of articles were published in the 2000s (n=43) and 1990s (n=38). Articles were published across 10 journals, most commonly Statistics in medicine (n=71) and Medical decision making (n=28). The articles had an average of 2.47 authors. Statistics and biostatistics modeling was the most common topic (n=71), followed by artificial intelligence (n=12), and medical errors (n=3), other topics included data mining, diagnosis, bioinformatics, information retrieval, and medical imaging. Our bibliometric analysis illustrated a historical perspective on the progress of scientific research on Medical Informatics. Moreover, the findings of the current study provide an insight on the frequency of citations for top cited articles published in Medical Informatics as well as quality of the works, journals, and the trends steering Medical Informatics.

    It is difficult for sites affected by mining to be colonized by vegetation and thus they suffer a slow recovery to a healthy ecosystem and, as a result, restoration work is necessary. The aim of this report is to propose a set of native species which are conducive to establishing a stable and self-sufficient plant community that will protect the soil and contribute to the rapid integration into the landscape of the areas affected by mining in the upper basin of the river Rodrigatos in the region of El Bierzo (Leon) An analysis of plant communities was undertaken using the phyto sociological method of Braun-Blanquet in order to subsequently select, using ecological criteria, the most suitable species for revegetation. Plant mapping using ortho photos was also developed in order to identify and delineate the location of the different landscape units. Among candidate species, in the first revegetation phase, we suggest a variety of herbs that are able to fix soils and protect them from erosion; species of the genus Cytisus and Genista in areas of moderate slope and species such as Rumex induratus Boiss and Reuter, Erysimum linifolium (Pourr. Ex Pers .) Jay in steeper areas because of their rooting ability. In later stages, the introduction of tree species characteristic for each formation is recommended. Furthermore, in the riverside areas species such as Carex elata subsp.reuteriana (Boiss.) Lucen and Aedo, Alnus glutinosa (L.) and Salix atrocinerea Brot. are proposed for introduction from the fi rst stage onwards. The species proposed in this study include some not commonly used in restoration, so a subsequent more detailed study would be required in order to assess their degree of suitability for this use.

    The Triological Society requires thesis submission for full membership. Accepted theses (AT) may be recognized with designations of: Mosher Awards (MA), Fowler Awards (FA), Honorable Mention for Basic Science (HMBS), and Honorable Mention for Clinical Science (HMCS). We sought to determine and compare the scholarly impact of Triological Society theses, their authors, and whether differences exist between AT and those that receive special recognition. Retrospective analysis of awards and theses compiled by The Triological Society home office from 1998 to 2011. Thomson Reuters' Integrated Search Interface (ISI) Web of Knowledge and Google Scholar and were used to determine citations and the author's h-index. Trend and statistical analysis was performed. Of the 307 Triological Society theses examined, 275 were published and had record of citation. H-indices and number of citations were found to be nonparametric; thus, median and quartile (1(st) -3(rd) quartiles) values were found to be the following: AT 11 (4-26), MA 18 (9-25), FA 6 (1-28), HMBS 11 (4-26), and HMCS 16 (1-28) for number of citations per published thesis. H-indices of authors with accepted theses were AT 15 (10-19), MA 16 (15-23), FA 18 (10-23), HMBS 16 (11-19), and HMCS 15 (11-21). When comparing all groupings of theses and award winners with bibliometric indices, no statistical significance was found (P >0.5). The Triological Society cultivates a competitive pool of applicants as membership is highly regarded. Negligible difference in citations and author h-index were observed between AT, MA, and FA theses indicated that the level of excellence is uniform, and thesis submission remains influential and prestigious.

    Bibliometric review of the literature. To analyze and quantify the most frequently cited papers in lumbar spine surgery and to measure their impact on the entire lumbar spine literature. Lumbar spine surgery is a dynamic and complex field. Basic science and clinical research remain paramount in understanding and advancing the field. While new literature is published at increasing rates, few studies make long-lasting impacts. The Thomson Reuters Web of Knowledge was searched for citations of all papers relevant to lumbar spine surgery. The number of citations, authorship, year of publication, journal of publication, country of publication, and institution were recorded for each paper. The most cited paper was found to be the classic paper from 1990 by Boden et al that described magnetic resonance imaging findings in individuals without back pain, sciatica, and neurogenic claudication showing that spinal stenosis and herniated discs can be incidentally found when scanning patients. The second most cited study similarly showed that asymptomatic patients who underwent lumbar spine magnetic resonance imaging frequently had lumbar pathology. The third most cited paper was the 2000 publication of Fairbank and Pynsent reviewing the Oswestry Disability Index, the outcome-measure questionnaire most commonly used to evaluate low back pain. The majority of the papers originate in the United States (n=58), and most were published in Spine (n=63). Most papers were published in the 1990s (n=49), and the 3 most common topics were low back pain, biomechanics, and disc degeneration. This report identifies the top 100 papers in lumbar spine surgery and acknowledges those individuals who have contributed the most to the advancement of the study of the lumbar spine and the body of knowledge used to guide evidence-based clinical decision making in lumbar spine surgery today. 3.

    Full Text Available Abstract Background The objective of this study was to characterize insulin use and examine factors associated with persistence to mealtime insulin among patients with type 2 diabetes (T2D on stable basal insulin therapy initiating mealtime insulin therapy. Methods Insulin use among patients with T2D initiating mealtime insulin was investigated using Thomson Reuters MarketScan® research databases from July 2001 through September 2006. The first mealtime insulin claim preceded by 6 months with 2 claims for basal insulin was used as the index event. A total of 21 months of continuous health plan enrollment was required. Patients were required to have a second mealtime insulin claim during the 12-month follow-up period. Persistence measure 1 defined non-persistence as the presence of a 90-day gap in mealtime insulin claims, effective the date of the last claim prior to the gap. Persistence measure 2 required 1 claim per quarter to be persistent. Risk factors for non-persistence were assessed using logistic regression. Results Patients initiating mealtime insulin (n = 4752; 51% male, mean age = 60.3 years primarily used vial/syringe (87% and insulin analogs (60%. Patients filled a median of 2, 3, and 4 mealtime insulin claims at 3, 6, and 12 months, respectively, with a median time of 76 days between refills. According to measure 1, persistence to mealtime insulin was 40.7%, 30.2%, and 19.1% at 3, 6, and 12 months, respectively. Results for measure 2 were considerably higher: 74.3%, 55.3%, and 42.2% of patients were persistent at 3, 6, and 12 months, respectively. Initiating mealtime insulin with human insulin was a risk factor for non-persistence by both measures (OR Conclusions Mealtime insulin use and persistence were both considerably lower than expected, and were significantly lower for human insulin compared to analogs.

    Full Text Available INTRODUCTION Authors of academic works do not take full advantage of the self-archiving rights that they retain in their publications, though research shows that many academic authors are well-aligned (at least in principle with open access (OA principles. This article explains how institutionally-assisted self-archiving in open access repositories can effectively take advantage of retained rights and highlights at least one method of facilitating this process through automated means. METHODS To understand the scope of author-retained rights (including the right to purchase hybrid or other open access options at some sample universities, author-rights data through the SHERPA/RoMEO API was combined with individual article citations (from Thomson Reuters' Web of Science for works published over a one-year period (2011 and authored by individuals affiliated with five major U.S. research universities. RESULTS Authors retain significant rights in the articles that they create. Of the 29,322 unique articles authored over the one year period at the five universities, 28.83 percent could be archived in final PDF form and 87.95 percent could be archived as the post-print version. Nearly 43.47 percent also provided authors the choice of purchasing a hybrid paid open access option. DISCUSSION A significant percentage of current published output could be archived with little or no author intervention. With prior approval through an open access policy or otherwise, article manuscripts or final PDFs can be obtained and archived by library staff, and hybrid paid-OA options could be negotiated and exploited by library administrators. CONCLUSION Although mandates, legislation, and other policy tools may be useful to promote open access, many institutions already have the ability to increase the percentage of accessible works by taking advantage of retained author rights and hybrid OA options.

    The aim of this study is to investigate the frequency of incorrect citations and its effects on the impact factor of a specific biomedical journal: the American Journal of Roentgenology. The Cited Reference Search function of Thomson Reuters' Web of Science database (formerly the Institute for Scientific Information's Web of Knowledge database) was used to identify erroneous citations. This was done by entering the journal name into the Cited Work field and entering "2011-2012" into the Cited Year(s) field. The errors in any part of the inaccurately cited references (e.g., author names, title, year, volume, issue, and page numbers) were recorded, and the types of errors (i.e., absent, deficient, or mistyped) were analyzed. Erroneous citations were corrected using the Suggest a Correction function of the Web of Science database. The effect of inaccurate citations on the impact factor of the AJR was calculated. Overall, 183 of 1055 citable articles published in 2011-2012 were inaccurately cited 423 times (mean [± SD], 2.31 ± 4.67 times; range, 1-44 times). Of these 183 articles, 110 (60.1%) were web-only articles and 44 (24.0%) were print articles. The most commonly identified errors were page number errors (44.8%) and misspelling of an author's name (20.2%). Incorrect citations adversely affected the impact factor of the AJR by 0.065 in 2012 and by 0.123 in 2013. Inaccurate citations are not infrequent in biomedical journals, yet they can be detected and corrected using the Web of Science database. Although the accuracy of references is primarily the responsibility of authors, the journal editorial office should also define a periodic inaccurate citation check task and correct erroneous citations to reclaim unnecessarily lost credit.

    To date, there have been no reports in the current literature regarding the use of the Accreditation Council for Graduate Medical Education (ACGME) core competencies in otolaryngology residency training. An evaluation may help educators address these core competencies in the training curriculum. To examine the quantity and nature of otolaryngology residency training literature through a systematic review and to evaluate whether this literature aligns with the 6 core competencies. A medical librarian assisted in a search of all indexed years of the PubMed, Embase, Education Resources Information Center (via EBSCOhost), Cochrane Library (Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials, and Cochrane Methodology Register), Thomson Reuters Web of Science (Science Citation Index Expanded, Social Sciences Citation Index Expanded, Conference Proceedings Citation Index-Science, and Conference Proceedings Citation Index-Social Science and Humanities), Elsevier Scopus, and ClinicalTrials.gov databases to identify relevant English-language studies. Included studies contained original human data and focused on otolaryngology resident education. Data regarding study design, setting, and ACGME core competencies addressed were extracted from each article. Initial searches were performed on May 20, 2015, and updated on October 4, 2016. In this systematic review of 104 unique studies, interpersonal communication skills were reported 15 times; medical knowledge, 48 times; patient care, 44 times; practice-based learning and improvement, 31 times; professionalism, 15 times; and systems-based practices, 10 times. Multiple studies addressed more than 1 core competency at once, and 6 addressed all 6 core competencies. Increased emphasis on nonclinical core competencies is needed, including professionalism, interpersonal and communication skills, and systems-based practices in the otolaryngology residency training curriculum.

    A number of new metrics based on social media platforms--grouped under the term "altmetrics"--have recently been introduced as potential indicators of research impact. Despite their current popularity, there is a lack of information regarding the determinants of these metrics. Using publication and citation data from 1.3 million papers published in 2012 and covered in Thomson Reuters' Web of Science as well as social media counts from Altmetric.com, this paper analyses the main patterns of five social media metrics as a function of document characteristics (i.e., discipline, document type, title length, number of pages and references) and collaborative practices and compares them to patterns known for citations. Results show that the presence of papers on social media is low, with 21.5% of papers receiving at least one tweet, 4.7% being shared on Facebook, 1.9% mentioned on blogs, 0.8% found on Google+ and 0.7% discussed in mainstream media. By contrast, 66.8% of papers have received at least one citation. Our findings show that both citations and social media metrics increase with the extent of collaboration and the length of the references list. On the other hand, while editorials and news items are seldom cited, it is these types of document that are the most popular on Twitter. Similarly, while longer papers typically attract more citations, an opposite trend is seen on social media platforms. Finally, contrary to what is observed for citations, it is papers in the Social Sciences and humanities that are the most often found on social media platforms. On the whole, these findings suggest that factors driving social media and citations are different. Therefore, social media metrics cannot actually be seen as alternatives to citations; at most, they may function as complements to other type of indicators.

    An increasing number of clinical and epidemiological studies suggest a possible association between attention-deficit/hyperactivity disorder (ADHD) and obesity/overweight. However, overall evidence is mixed. Given the public health relevance of ADHD and obesity/overweight, understanding whether and to what extent they are associated is paramount to plan intervention and prevention strategies. We describe the protocol of a systematic review and meta-analysis aimed at assessing the prevalence of obesity/overweight in individuals with ADHD versus those without ADHD. We will include studies of any design (except case reports or case series) comparing the prevalence of obesity and/or overweight in children or adults with and without ADHD (or hyperkinetic disorder). We will search an extensive number of databases including PubMed, Ovid databases, Web of Knowledge and Thomson-Reuters databases, ERIC and CINAHL. No restrictions of language will be applied. We will also contact experts in the field for possible unpublished or in press data. Primary and additional outcomes will be the prevalence of obesity and overweight, respectively. We will combine ORs using random-effects models in STATA V.12.0. The quality of the study will be assessed primarily using the Newcastle-Ottawa Scale. Subgroup meta-analyses will be conducted according to participants' age (children vs adults) and study setting (clinical vs general population). We will explore the feasibility of conducting meta-regression analyses to assess the moderating effect of age, gender, socioeconomic status, study setting, geographic location of the study (low-income, middle-income countries vs high-income countries), definition of obesity, method to assess ADHD, psychiatric comorbidities and medication status. No ethical issues are foreseen. The results will be published in a peer-reviewed journal and presented at national and international conferences of psychiatry, psychology, obesity and paediatrics.

    Full Text Available T2A-1 is a newly developed transgenic rice that expresses a synthesized cry2Aa gene driven by the maize ubiquitin promoter. T2A-1 exhibits high resistance against lepidopteran pests of rice. The brown planthopper, Nilapavarta lugens (Stål, is a main nontarget sap-sucking insect pest of rice, and Cyrtorhinus lividipennis (Reuter is the major predator of the eggs and young nymphs of planthoppers. As C. lividipennis may expose to the Cry2Aa protein via N. lugens, it is therefore essential to assess the potential effects of transgenic cry2Aa rice on this predator. In the present study, three experiments were conducted to evaluate the ecological risk of transgenic cry2Aa rice to C. lividipennis: (1 a direct feeding experiment in which C. lividipennis was fed an artificial diet containing Cry2Aa at the dose of 10-time higher than that it may encounter in the realistic field condition; (2 a tritrophic experiment in which the Cry2Aa protein was delivered to C. lividipennis indirectly through prey eggs or nymphs; (3 a realistic field experiment in which the population dynamics of C. lividipennis were investigated using vacuum-suction. Both direct exposure to elevated doses of the Cry2Aa protein and prey-mediated exposure to realistic doses of the protein did not result in significant detrimental effects on the development, survival, female ratio and body weight of C. lividipennis. No significant differences in population density and population dynamics were observed between C. lividipennis in transgenic cry2Aa and nontransgenic rice fields. It may be concluded that transgenic cry2Aa rice had no detrimental effects on C. lividipennis. This study represents the first report of an assessment continuum for the effects of transgenic cry2Aa rice on C. lividipennis.

  16. Differences in Investigator-Initiated Trials between Japan and Other Countries: Analyses of Clinical Trials Sponsored by Academia and Government in the ClinicalTrials.gov Registry and in the Three Japanese Registries.

    Full Text Available Following the amendment of the Pharmaceutical Affairs Law in Japan in 2003 researchers were permitted to begin investigator-initiated trials (IITs. In subsequent years, however, the number of IITs remained low. In other countries in Asia as well as in Europe, North America, and South Africa, the number of IITs has increased over the past decade. The differences in the characteristics of IITs between Japan and other countries are unknown. Some studies have analyzed the characteristics of all clinical trials according to registry databases, but there has been less research focusing on IITs.The purpose of this study is to analyze the characteristics of IITs in the ClinicalTrials.gov registry and in the three Japanese registries, to identify differences in IITs between Japan and other countries.Using Thomson Reuters Pharma™, trials sponsored by academia and government as IITs in 2010 and registered in ClinicalTrials.gov were identified. IITs from 2004 to 2012 in Japan were identified in the three Japanese registries: the University Hospital Medical Information Network Clinical Trials Registry, the Japan Pharmaceutical Information Center Clinical Trials Information, and the Japan Medical Association Center for Clinical Trials, Clinical Trials Registry. Characterization was made of the trial purposes, phases, participants, masking, arms, design, controls, and other data.New and revised IITs registered in ClinicalTrials.gov during 2010 averaged about 40% of all sponsor-identified trials. IITs were nearly all early-phase studies with small numbers of participants. A total of 56 Japanese IITs were found over a period of 8 years, and these were also almost nearly all early-phase studies with small numbers of participants.There appear to be no great differences between Japan and other countries in terms of characteristics of IITs. These results should prompt a new review of the IIT environment in Japan.

    It is difficult for sites affected by mining to be colonized by vegetation and thus they suffer a slow recovery to a healthy ecosystem and, as a result, restoration work is necessary. The aim of this report is to propose a set of native species which are conducive to establishing a stable and self-sufficient plant community that will protect the soil and contribute to the rapid integration into the landscape of the areas affected by mining in the upper basin of the river Rodrigatos in the region of El Bierzo (Leon) An analysis of plant communities was undertaken using the phyto sociological method of Braun-Blanquet in order to subsequently select, using ecological criteria, the most suitable species for revegetation. Plant mapping using ortho photos was also developed in order to identify and delineate the location of the different landscape units. Among candidate species, in the first revegetation phase, we suggest a variety of herbs that are able to fix soils and protect them from erosion; species of the genus Cytisus and Genista in areas of moderate slope and species such as Rumex induratus Boiss and Reuter, Erysimum linifolium (Pourr. Ex Pers .) Jay in steeper areas because of their rooting ability. In later stages, the introduction of tree species characteristic for each formation is recommended. Furthermore, in the riverside areas species such as Carex elata subsp.reuteriana (Boiss.) Lucen and Aedo, Alnus glutinosa (L.) and Salix atrocinerea Brot. are proposed for introduction from the fi rst stage onwards. The species proposed in this study include some not commonly used in restoration, so a subsequent more detailed study would be required in order to assess their degree of suitability for this use.

    The article presents a general idea of Industry 4.0 concept with the introduction presenting descriptions of the most important aspects in terms of production and construction industry development. The importance of the SME sector is stressed showing that this group of companies plays significant role in the European economy. The main objective of the article is to define and show possible research areas connected with the introduction of Industry 4.0 concept into SMEs with the main focus on the construction sector. For this purpose, an analysis was made, based on the most recent literature, to point out actual needs in the SMEs sector in terms of its evolution into 4.0 level. What is more, the analysis was performed based on the most popular articles published in journals available in Thomson Reuters Web of Science Core Collection database regarding Industry 4.0 concept in the last decade showing the actual change of interest in this filed, taking into account possibility of usage of this concept in the construction and production sector. Authors tried to describe current knowledge regarding Industry 4.0 introduction for SMEs. Performed analysis showed that there is a wide spectrum of disciplines that are affected by the Industry 4.0 that needs to be examined considering introduction into SMEs. Study also showed that multidiscipline approach was not investigated so far to create special rules, procedures and methods and know-how designed for introduction of main principles of Industry 4.0 in the SME sector. Authors came to the conclusions that there should be more stress put into research in this field especially taking into account the huge potential which lies in SME sector in terms of global economic strength.

    The relative gas multiplication along the cylindrical axis of three 3 He proportional counters with different length were measured by using a thermal neutron beam at the Kyoto University Reactor and an ideal response function by taking into account the difference of pulse height spectra were measured by different length counters. The three 3 He proportional counters (model type of P4-0806, P4-0806 and P4-0808 manufactured by Reuter-Stokes) prepared for relative gas multiplication measurements had identical structure having cylindrical outer shells of 304 stainless steel except for different sensitive lengths of 10 cm, 15 cm and 20 cm, respectively. All counters were filled with 400 kPa of 3 He gas and 200 kPa of Ar gas. The pulse height distributions were measured by moving the counter in the direction of it's cylindrical axis perpendicular to the thermal neutron beam. The measured pulse heights corresponding to the full energy peaks at various entrance points were normalized to that of the whole counter irradiation. The results as a function of the distance from the bottom edge of the stainless steel cylinder are shown. The total transition region of gas gain corresponded to about 23 %, 15 % and 10 % of each nominal sensitive region corresponding to shot, middle and long counters. The ideal pulse height spectrum (dots) obtained by using proportional counters of 10 cm and 20 cm in nominal sensitive length to thermal neutron beam is shown in the paper in comparison to simulated one which was calculated assuming the constant gain within the sensitive region and zero gas gain outside the sensitive regions. The simulation realized the ideal response function fairly well. (S.Y.)

    To assess the quality of the randomized clinical trial (RCT) reports published in Endodontics between 1997 and 2012. Retrieval of RCTs in Endodontics was based on a search of the Thomson Reuters Web of Science (WoS) database (March 2013). Quality evaluation was performed using a checklist based on the Jadad criteria, CONSORT (Consolidated Standards of Reporting Trials) statement and SPIRIT (Standard Protocol Items: Recommendations for Interventional Trials). Descriptive statistics were used for frequency distribution of data. Student's t-test and Welch test were used to identify the influence of certain trial characteristics upon report quality (α = 0.05). A total of 89 RCTs were evaluated, and several methodological flaws were found: only 45% had random sequence generation at low risk of bias, 75% did not provide information on allocation concealment, and 19% were nonblinded designs. Regarding statistics, only 55% of the RCTs performed adequate sample size estimations, only 16% presented confidence intervals, and 25% did not provide the exact P-value. Also, 2% of the articles used no statistical tests, and in 87% of the RCTs, the information provided was insufficient to determine whether the statistical methodology applied was appropriate or not. Significantly higher scores were observed for multicentre trials (P = 0.023), RCTs signed by more than 5 authors (P = 0.03), articles belonging to journals ranked above the JCR median (P = 0.03), and articles complying with the CONSORT guidelines (P = 0.000). The quality of RCT reports in key areas for internal validity of the study was poor. Several measures, such as compliance with the CONSORT guidelines, are important in order to raise the quality of RCTs in Endodontics. © 2016 International Endodontic Journal.

    2018-01-01

    If a doctoral dissertation represents an original investigation that makes a contribution to one's field, then dissertation research could, and arguably should, be disseminated into the scientific literature. However, the extent and nature of dissertation publication remains largely unknown within psychology. The present study investigated the peer-reviewed publication outcomes of psychology dissertation research in the United States. Additionally, we examined publication lag, scientific impact, and variations across subfields. To investigate these questions, we first drew a stratified random cohort sample of 910 psychology Ph.D. dissertations from ProQuest Dissertations & Theses. Next, we conducted comprehensive literature searches for peer-reviewed journal articles derived from these dissertations published 0-7 years thereafter. Published dissertation articles were coded for their bibliographic details, citation rates, and journal impact metrics. Results showed that only one-quarter (25.6% [95% CI: 23.0, 28.4]) of dissertations were ultimately published in peer-reviewed journals, with significant variations across subfields (range: 10.1 to 59.4%). Rates of dissertation publication were lower in professional/applied subfields (e.g., clinical, counseling) compared to research/academic subfields (e.g., experimental, cognitive). When dissertations were published, however, they often appeared in influential journals (e.g., Thomson Reuters Impact Factor M = 2.84 [2.45, 3.23], 5-year Impact Factor M = 3.49 [3.07, 3.90]) and were cited numerous times (Web of Science citations per year M = 3.65 [2.88, 4.42]). Publication typically occurred within 2-3 years after the dissertation year. Overall, these results indicate that the large majority of Ph.D. dissertation research in psychology does not get disseminated into the peer-reviewed literature. The non-publication of dissertation research appears to be a systemic problem affecting both research and training in psychology

  2. Risks, prices, and positions: A social network analysis of illegal drug trafficking in the world-economy.

    Illegal drug prices are extremely high, compared to similar goods. There is, however, considerable variation in value depending on place, market level and type of drugs. A prominent framework for the study of illegal drugs is the "risks and prices" model (Reuter & Kleiman, 1986). Enforcement is seen as a "tax" added to the regular price. In this paper, it is argued that such economic models are not sufficient to explain price variations at country-level. Drug markets are analysed as global trade networks in which a country's position has an impact on various features, including illegal drug prices. This paper uses social network analysis (SNA) to explain price markups between pairs of countries involved in the trafficking of illegal drugs between 1998 and 2007. It aims to explore a simple question: why do prices increase between two countries? Using relational data from various international organizations, separate trade networks were built for cocaine, heroin and cannabis. Wholesale price markups are predicted with measures of supply, demand, risks of seizures, geographic distance and global positioning within the networks. Reported prices (in $US) and purchasing power parity-adjusted values are analysed. Drug prices increase more sharply when drugs are headed to countries where law enforcement imposes higher costs on traffickers. The position and role of a country in global drug markets are also closely associated with the value of drugs. Price markups are lower if the destination country is a transit to large potential markets. Furthermore, price markups for cocaine and heroin are more pronounced when drugs are exported to countries that are better positioned in the legitimate world-economy, suggesting that relations in legal and illegal markets are directed in opposite directions. Consistent with the world-system perspective, evidence is found of coherent world drug markets driven by both local realities and international relations. Copyright © 2013 Elsevier B

  3. ‘Publish or perish’: Family life and academic research productivity

    2016-05-01

    Full Text Available Research purpose: The influence of work-to-family and family-to-work spillovers is well documented in the human resources literature. However, little is known of the relationships between the pressures faced by academics to publish and the potential family life consequences of being a highly productive academic. Research design, approach and method: This research sought to investigate these relationships within the context of a large South African university by testing associations between family life variables such as marriage and dependent children against measures of the following specific types of research publication: (1 South African Department of Higher Education and Training–accredited journal publications; (2 Thompson Reuters Institute for Scientific Information (ISI and ProQuest’s International Bibliography of the Social Sciences (IBSS– indexed journal article publications; (3 conference proceedings publications; (4 conference paper presentations; (5 book chapter publications; (6 book publications; and (7 gross research productivity, reflecting a volume or quantity measure of research publication. Main findings: ISI and/or IBSS journal article publication is found to be negatively associated with dependent children, but only for male academics, and to be negatively associated with female gender over and above the effect of family life variables in testing. Practical/managerial implications: Human resources managers in universities need to be cognisant of the specific pressures faced by staff that are required to produce ever more research publications, in order to help them achieve work–life balance. Contribution: In a global context of increasing pressures for research publication, and for higher and higher numbers of publications, it is necessary to identify the potential costs involved for high-volume–producing academics, particularly in terms of family versus work. Keywords: research productivity; family-work life balance

    Argonne National Laboratory (ANL) together with the University of North Texas (UNT) have developed an improved method for converting refuse (residential, commercial and institutional waste) into an environmentally safe and economical fuel. In this method, recyclable metals, glass, and some plastic products are separated from the refuse. The remaining fraction, consisting primarily of cellulosic materials is then combined with a calcium hydroxide binding additive and formed into cylindrical pellets. These pellets are dense and odorless, can be stored for extended periods of time without biological or chemical degradation, and due to their increased bulk density are more durable and can be more easily conveyed, handled, and transported than other types of waste-derived fuel pellets. Laboratory and pilot-scale research studies, followed by full-scale combustion tests undertaken by DOE, ANL and UNT, in June--July of 1987 have indicated that binder-enhanced dRDF pellets can be successfully cofired with high sulfur coal in spreader-stoker combustors. The results of these combustion tests indicated significant reductions of SO 2 , NO x and CO 2 in the flue gases, and the reduction of heavy metals and organics in the ash residue. Dioxins and furans, both in the flue gas and in the ash residues were below detectable levels. Additional commercial-scale combustion tests have recently been conducted by DOE, NREL, ANL and several industrial participants including Otter Tail Power Company, Reuter, Inc., XL Recycling and Marblehead Lime Company, under a collaborative research and development agreement (CRADA). A large 440 MW e cyclone-fired combustor was tested at Big Stone City, South Dakota on October 26--27, 1992. This paper describes the cyclone-fired combustion tests, the flue gas emission and ash samples that were collected, the analyses that were performed on these samples, and the final test results

    Full Text Available Global maps of science can be used as a reference system to chart career trajectories, the location of emerging research frontiers, or the expertise profiles of institutes or nations. This paper details data preparation, analysis, and layout performed when designing and subsequently updating the UCSD map of science and classification system. The original classification and map use 7.2 million papers and their references from Elsevier's Scopus (about 15,000 source titles, 2001-2005 and Thomson Reuters' Web of Science (WoS Science, Social Science, Arts & Humanities Citation Indexes (about 9,000 source titles, 2001-2004-about 16,000 unique source titles. The updated map and classification adds six years (2005-2010 of WoS data and three years (2006-2008 from Scopus to the existing category structure-increasing the number of source titles to about 25,000. To our knowledge, this is the first time that a widely used map of science was updated. A comparison of the original 5-year and the new 10-year maps and classification system show (i an increase in the total number of journals that can be mapped by 9,409 journals (social sciences had a 80% increase, humanities a 119% increase, medical (32% and natural science (74%, (ii a simplification of the map by assigning all but five highly interdisciplinary journals to exactly one discipline, (iii a more even distribution of journals over the 554 subdisciplines and 13 disciplines when calculating the coefficient of variation, and (iv a better reflection of journal clusters when compared with paper-level citation data. When evaluating the map with a listing of desirable features for maps of science, the updated map is shown to have higher mapping accuracy, easier understandability as fewer journals are multiply classified, and higher usability for the generation of data overlays, among others.

    Team science involving multidisciplinary and multi-institutional collaboration is increasingly recognized as a means of strengthening the quality of scientific research. The aim of this study was to assess associations between various forms of collaboration and the citation impact of published radiology research. In 2010, 876 original research articles published in Academic Radiology, the American Journal of Roentgenology, JACR, and Radiology were identified with at least one radiology-affiliated author. All articles were manually reviewed to extract features related to all authors' disciplines and institutions. Citations to these articles through September 2016 were extracted from Thomson Reuters Web of Science. Subsequent journal article citation counts were significantly higher (P < .05) for original research articles with at least seven versus six or fewer authors (26.2 ± 30.8 versus 20.3 ± 23.1, respectively), with authors from multiple countries versus from a single country (32.3 ± 39.2 versus 22.0 ± 25.0, respectively), with rather than without a nonuniversity collaborator (28.7 ± 38.6 versus 22.4 ± 24.9, respectively), and with rather than without a nonclinical collaborator (26.5 ± 33.1 versus 21.9 ± 24.4, respectively). On multivariate regression analysis, the strongest independent predictors of the number of citations were authors from multiple countries (β = 9.14, P = .002), a nonuniversity collaborator (β = 4.80, P = .082), and at least seven authors (β = 4.11, P = .038). With respect to subsequent journal article citations, various forms of collaboration are associated with greater scholarly impact of published radiology research. To enhance the relevance of their research, radiology investigators are encouraged to pursue collaboration across traditional disciplinary, institutional, and geographic boundaries.

    Full Text Available Background: Traumatic Brain Injury (TBI is the leading cause of mortality and morbidity especially in young ages. Despite over 30 years of using Neuroprotective agents for TBI management, there is no absolute recommended agent for the condition yet. Methods: This study is a part of a scoping review thesis on "Neuroprotective agents using for Traumatic Brain Injury: a systematic review & meta-analyses"; which had a wide proposal keywords and ran in "Cochrane CENTRAL", "MedLine/PubMed", "SCOPUS", "Thomson Reuters Web of Science", "SID.ir", "Barket Foundation", and "clinicaltrials.gov" databases up to September 06, 2015. This study limits the retrieved search results only to those which used citicoline for TBI management. The included Randomized Clinical Trials' (RCTs were assessed for their quality of reporting by adapting CONSORT-checklist prior to extracting their data into meta-analysis. Meta-analyses of this review were conducted by Glasgow Outcome Scale (GOS in acute TBI patients and total neuropsychological assessments in both acute and chronic TBI management, mortalities and adverse-effects. Results: Four RCTs were retrieved and included in this review with 1196 participants (10 were chronic TBI impaired patients; analysis of 1128 patients for their favorable GOS outcomes in two studies showed no significant difference between the study groups; however, neuropsychological outcomes were significantly better in placebo/control group of 971 patients of three studies. Mortality rates and adverse-effects analysis based on two studies with 1429 patients showed no significant difference between the study groups. However, two other studies have neither mortality nor adverse effects reports due to their protocol. Conclusions: Citicoline use for acute TBI seems to have no field of support anymore, whereas it may have some benefits in improving the neuro-cognitive state in chronic TBI patients. It's also recommended to keep in mind acute interventions

    Today if you use the Thomson-Reuters Science Citations Index to search for "aerosol*", across all scientific disciplines and years, with no constraints, and you sort by number of citations, you will find a 2005 paper published in the Journal of the Atmospheric Sciences in the top 20. This is the "The MODIS Aerosol Algorithm, Products and Validation". Although I am the first author, there are in total 12 co-authors who each made a significant intellectual contribution to the paper or to the algorithm, products and validation described. This paper, that algorithm, those people lie at the heart of a lineage of scientists whose collaborations and linked individual pursuits have made a significant contribution to our understanding of radiative transfer and climate, of aerosol properties and the global aerosol system, of cloud physics and aerosol-cloud interaction, and how to measure these parameters and maximize the science that can be obtained from those measurements. The 'lineage' had its origins across the globe, from Soviet Russia to France, from the U.S. to Israel, from the Himalayas, the Sahel, the metropolises of Sao Paulo, Taipei, and the cities of east and south Asia. It came together in the 1990s and 2000s at the NASA Goddard Space Flight Center, using cultural diversity as a strength to form a common culture of scientific creativity that continues to this day. The original algorithm has spawned daughter algorithms that are being applied to new satellite and airborne sensors. The original MODIS products have been fundamental to analyses as diverse as air quality monitoring and aerosol-cloud forcing. AERONET, designed originally for the need of validation, is now its own thriving institution, and the lineage continues to push forward to provide new technology for the coming generations.

    Full Text Available As part of our drug discovery program for anti-filarial agents from Indian medicinal plants, leaves of Eucalyptus tereticornis were chemically investigated, which resulted in the isolation and characterization of an anti-filarial agent, ursolic acid (UA as a major constituent. Antifilarial activity of UA against the human lymphatic filarial parasite Brugia malayi using in vitro and in vivo assays, and in silico docking search on glutathione-s-transferase (GST parasitic enzyme were carried out. The UA was lethal to microfilariae (mf; LC100: 50; IC50: 8.84 µM and female adult worms (LC100: 100; IC50: 35.36 µM as observed by motility assay; it exerted 86% inhibition in MTT reduction potential of the adult parasites. The selectivity index (SI of UA for the parasites was found safe. This was supported by the molecular docking studies, which showed adequate docking (LibDock scores for UA (-8.6 with respect to the standard antifilarial drugs, ivermectin (IVM -8.4 and diethylcarbamazine (DEC-C -4.6 on glutathione-s-transferase enzyme. Further, in silico pharmacokinetic and drug-likeness studies showed that UA possesses drug-like properties. Furthermore, UA was evaluated in vivo in B. malayi-M. coucha model (natural infection, which showed 54% macrofilaricidal activity, 56% female worm sterility and almost unchanged microfilaraemia maintained throughout observation period with no adverse effect on the host. Thus, in conclusion in vitro, in silico and in vivo results indicate that UA is a promising, inexpensive, widely available natural lead, which can be designed and developed into a macrofilaricidal drug. To the best of our knowledge this is the first ever report on the anti-filarial potential of UA from E. tereticornis, which is in full agreement with the Thomson Reuter's 'Metadrug' tool screening predictions.

  11. What we remember affects how we see: spatial working memory steers saccade programming.

    Wong, Jason H; Peterson, Matthew S

    2013-02-01

    Relationships between visual attention, saccade programming, and visual working memory have been hypothesized for over a decade. Awh, Jonides, and Reuter-Lorenz (Journal of Experimental Psychology: Human Perception and Performance 24(3):780-90, 1998) and Awh et al. (Psychological Science 10(5):433-437, 1999) proposed that rehearsing a location in memory also leads to enhanced attentional processing at that location. In regard to eye movements, Belopolsky and Theeuwes (Attention, Perception & Psychophysics 71(3):620-631, 2009) found that holding a location in working memory affects saccade programming, albeit negatively. In three experiments, we attempted to replicate the findings of Belopolsky and Theeuwes (Attention, Perception & Psychophysics 71(3):620-631, 2009) and determine whether the spatial memory effect can occur in other saccade-cuing paradigms, including endogenous central arrow cues and exogenous irrelevant singletons. In the first experiment, our results were the opposite of those in Belopolsky and Theeuwes (Attention, Perception & Psychophysics 71(3):620-631, 2009), in that we found facilitation (shorter saccade latencies) instead of inhibition when the saccade target matched the region in spatial working memory. In Experiment 2, we sought to determine whether the spatial working memory effect would generalize to other endogenous cuing tasks, such as a central arrow that pointed to one of six possible peripheral locations. As in Experiment 1, we found that saccade programming was facilitated when the cued location coincided with the saccade target. In Experiment 3, we explored how spatial memory interacts with other types of cues, such as a peripheral color singleton target or irrelevant onset. In both cases, the eyes were more likely to go to either singleton when it coincided with the location held in spatial working memory. On the basis of these results, we conclude that spatial working memory and saccade programming are likely to share common

    Introduction How the burden of disease varies during different phases after floods and after storms is essential in order to guide a medical response, but it has not been well-described. The objective of this review was to elucidate the health problems following flood and storm disasters. A literature search of the databases Medline (US National Library of Medicine, National Institutes of Health; Bethesda, Maryland USA); Cinahl (EBSCO Information Services; Ipswich, Massachusetts USA); Global Health (EBSCO Information Services; Ipswich, Massachusetts USA); Web of Science Core Collection (Thomson Reuters; New York, New York USA); Embase (Elsevier; Amsterdam, Netherlands); and PubMed (National Center for Biotechnology Information, National Institutes of Health; Bethesda, Maryland USA) was conducted in June 2015 for English-language research articles on morbidity or mortality and flood or storm disasters. Articles on mental health, interventions, and rescue or health care workers were excluded. Data were extracted from articles that met the eligibility criteria and analyzed by narrative synthesis. The review included 113 studies. Poisonings, wounds, gastrointestinal infections, and skin or soft tissue infections all increased after storms. Gastrointestinal infections were more frequent after floods. Leptospirosis and diabetes-related complications increased after both. The majority of changes occurred within four weeks of floods or storms. Health changes differently after floods and after storms. There is a lack of data on the health effects of floods alone, long-term changes in health, and the strength of the association between disasters and health problems. This review highlights areas of consideration for medical response and the need for high-quality, systematic research in this area. Saulnier DD , Brolin Ribacke K , von Schreeb J .

    Molecular imaging (MI) entails the visualisation, characterisation, and measurement of biologic processes at the molecular and cellular levels in humans and other living systems. Translating this technology to interventions in real-time enables interventional MI/image-guided surgery, for example, by providing better detection of tumours and their dimensions. To summarise and critically analyse the available evidence on image-guided surgery for genitourinary (GU) oncologic diseases. A comprehensive literature review was performed using PubMed and the Thomson Reuters Web of Science. In the free-text protocol, the following terms were applied: molecular imaging, genitourinary oncologic surgery, surgical navigation, image-guided surgery, and augmented reality. Review articles, editorials, commentaries, and letters to the editor were included if deemed to contain relevant information. We selected 79 articles according to the search strategy based on the Preferred Reporting Items for Systematic Reviews and Meta-analysis criteria and the IDEAL method. MI techniques included optical imaging and fluorescent techniques, the augmented reality (AR) navigation system, magnetic resonance imaging spectroscopy, positron emission tomography, and single-photon emission computed tomography. Experimental studies on the AR navigation system were restricted to the detection and therapy of adrenal and renal malignancies and in the relatively infrequent cases of prostate cancer, whereas fluorescence techniques and optical imaging presented a wide application of intraoperative GU oncologic surgery. In most cases, image-guided surgery was shown to improve the surgical resectability of tumours. Based on the evidence to date, image-guided surgery has promise in the near future for multiple GU malignancies. Further optimisation of targeted imaging agents, along with the integration of imaging modalities, is necessary to further enhance intraoperative GU oncologic surgery. Copyright © 2013

    In this study, we bibliometrically evaluated the top 100 cited articles on urological emergencies published since 1975 with a multidisciplinary and interdisciplinary perspective. We obtained the data for this study from the Thomson Reuters Web of Science and PubMed. We determined 360 articles which were related directly or indirectly to urological emergencies between 1975 and 2017 and analyzed retrospectively the top 100 cited articles among these. The mean citation impact factor of the top 100 cited articles was 25.8±50.1 (range: 4-467) between 1991 and 2014. We determined that classical articles were cited for 2588 times and the total number of self-citations was 23 (0.8%). Highest publication rate per year was in 2006 (n=9). Among the institutions which published ≥2 articles per year University of Texas led the way with 5 articles. The top 100 articles came from 27 countries and 58% of these are from the USA (n=29), the United Kingdom (n=23) and Germany (n=6). For the top 3 journals of the 33 of top 100 articles most frequently cited were published in journals with an impact factor ≥2 namely, Journal of Urology (n=15), British Journal of Urology International (n=13) and Urology (n=5) respectively. The most frequently cited main topics were penile emergencies with 22 articles and acute scrotal problems with 15 articles. Most of the classical articles on urological emergencies were based on clinical researches (n=95) and also we found that the average level of evidence for the top 100 cited articles was 4.16 (range: 1-5). Mostly preferred publishing language was English among this scientific papers (n=90). Although not considered as a completely unbiased and adequate criterion for scientific evaluations, analysis of the top 100 cited articles provides us with important current data on urological emergencies.

    This study assessed the publication performance of university departments of anesthesiology in Austria, Germany and Switzerland. The number of publications, original articles, impact factors and citations were evaluated. A search was performed in PubMed to identify publications related to anesthesiology from 2001 to 2010. All articles from anesthesiology journals listed in the fields of anesthesia/pain therapy, critical care and emergency medicine by the "journal citation report 2013" in Thomson Reuters ISI web of knowledge were included. Articles from non-anaesthesiology journals, where the stem of the word anesthesia (anes*, anaes*, anäst*, anast*) appears in the affiliation field of PubMed, were included as well. The time periods 2001-2005 and 2006-2010 were compared. Articles were allocated to university departments in Austria, Germany and Switzerland via the affiliation field. A total of 45 university departments in Austria, Germany and Switzerland and 125,979 publications from 2,863 journals (65 anesthesiology journals, 2,798 non-anesthesiology journals) were analyzed. Of the publications 23 % could not be allocated to a given university department of anesthesiology. In the observation period the university department of anesthesiology in Berlin achieved most publications (n = 479) and impact points (1,384), whereas Vienna accumulated most original articles (n = 156). Austria had the most publications per million inhabitants in 2006-2010 (n=50) followed by Switzerland (n=49) and Germany (n=35). The number of publications during the observation period decreased in Germany (0.5 %), Austria (7 %) and Switzerland (8 %). Tables 2 and 4-8 of this article are available at Springer Link under Supplemental. The research performance varied among the university departments of anesthesiology in Germany, Austria and Switzerland whereby larger university departments, such as Berlin or Vienna published most.

  16. Will growth in cryptomarket drug buying increase the harms of illicit drugs?

    2018-05-01

    Cryptomarkets-on-line, anonymous market-places for illicit goods and services that specialize mainly in drugs-account for a small but rapidly growing share of the illicit drug market in many countries. Policy responses so far are based generally on the assumption that their rise will only increase drug harms. In this contribution for debate, we question this assumption. We provide a narrative review of the emerging literature connected to drug cryptomarkets. We use MacCoun & Reuter's formula to understand the effect of population-level increases in use on total harm as depending on the level of harm associated with each unit of use. We then consider the potential for cryptomarkets to increase or decrease the harms and benefits related to each unit of drug use, with specific attention to the quality of drugs sold and the non-drug-related harms and benefits for customers. It is likely that cryptomarkets will increase both the amount and the range of substances that are sold. However, we argue that the effects on harms will depend upon whether cryptomarkets also increase the quality and safety of products that are sold, provide harm-reducing information to consumers and reduce transactional conflict involved in drug purchasing. There is an emerging and rapidly growing evidence base connected to the macro and micro harms and benefits of cryptomarkets for drug users. Future researchers should use appropriately matched comparative designs to establish more firmly the differential harms and benefits of sourcing drugs both on- and off-line. While it is unlikely that the on-line drug trade can be eradicated completely, cryptomarkets will respond to regulation and enforcement in ways that have complex, and sometimes unanticipated, effects on both harms and benefits. © 2017 The Authors.

    Full Text Available Background: Amelogenesis imperfecta (AI is a group of disorders that affect the enamel of the teeth, either in quality or quantity. This alteration causes sensitivity and is associated with factors that could affect the strength of the adhesive bond of the restorative material. Aim: To review the literature regarding the most used temporary restorative treatment in children and adolescents with AI. Methods: This scoping review aimed to include case reports, literature reviews and original studies that evaluated restorative materials for the teeth of children and adolescents with AI. Editorials, meeting abstracts and letters to the editor were excluded. The following electronic databases were used: Medline (Ovid, PubMed, Ebsco, Scopus (Elsevier and Web of Science (Thomson Reuters. Manual searches in the reference lists of the included articles were also carried out. Finally, a search in Google Scholar restricted to the first 100 hits was performed. Duplicates were eliminated upon identification. The search covered a period between the years of 2011 and 2016. PRISMA guidelines were used for reporting the review. The evidence ranking was carried out by means of the Oxford criteria. Results: Six articles met the eligibility criteria and were included in this scoping review. Three articles were case reports, one was a review and two were original studies. For the treatment of AI, direct or indirect composite resins were the most commonly used material of choice in the retrieved studies because they demonstrate greater longevity, aesthetics and function compared to the other materials used. Conclusions: Among children and adolescents with AI, the temporary restorative treatment that demonstrated better long-term results in permanent teeth was the direct and indirect composite resins. However, high quality studies should be conducted to confirm the results presented herein.

    This study aimed to compare the impact of Research&Development (R&D) expenditures on research publications, patents and high-tech exports among European countries. In this study, 47 European countries were included. The information regarding European countries, their per capita Gross Domestic Product (GDP), R&D spending, number of universities, indexed scientific journals, high technology exports and number of patents were collected. We recorded the total number of research documents in various science and social sciences subjects during the period 1996-2011. The main source for information was World Bank, Web of Science, Thomson Reuters and SCImago/Scopus. The mean GDP per capita for all the European countries is 23372.64 ± 3588.42 US$, yearly per capita spending on R&D 1.14 ± 0.13 US$, number of universities 48.17 ± 10.26, mean number of Institute of Scientific Information (ISI) indexed journal per country 90.72 ± 38.47, high technology exports 12.86 ± 1.59 and number of patent applications 61504.23 ± 22961.85. The mean of research documents published in various science and social science subjects among all the European countries during the period 1996-2011 is 213405.70 ± 56493.04. Spending on R&D, number of universities, indexed journals, high technology exports and number of patents have a positive correlation with number of published documents in various science and social science subjects. We found a positive correlation between patent application and high-tech exports. However, there was no association between GDP per capita and research outcomes. It is concluded that, the most important contributing factors towards a knowledge based economy are spending on R&D, number of universities, scientific indexed journals and research publications, which in turn give a boast to patents, high technology exports and ultimately GDP.

  19. Healthcare Text Classification System and its Performance Evaluation: A Source of Better Intelligence by Characterizing Healthcare Text.

    A machine learning (ML)-based text classification system has several classifiers. The performance evaluation (PE) of the ML system is typically driven by the training data size and the partition protocols used. Such systems lead to low accuracy because the text classification systems lack the ability to model the input text data in terms of noise characteristics. This research study proposes a concept of misrepresentation ratio (MRR) on input healthcare text data and models the PE criteria for validating the hypothesis. Further, such a novel system provides a platform to amalgamate several attributes of the ML system such as: data size, classifier type, partitioning protocol and percentage MRR. Our comprehensive data analysis consisted of five types of text data sets (TwitterA, WebKB4, Disease, Reuters (R8), and SMS); five kinds of classifiers (support vector machine with linear kernel (SVM-L), MLP-based neural network, AdaBoost, stochastic gradient descent and decision tree); and five types of training protocols (K2, K4, K5, K10 and JK). Using the decreasing order of MRR, our ML system demonstrates the mean classification accuracies as: 70.13 ± 0.15%, 87.34 ± 0.06%, 93.73 ± 0.03%, 94.45 ± 0.03% and 97.83 ± 0.01%, respectively, using all the classifiers and protocols. The corresponding AUC is 0.98 for SMS data using Multi-Layer Perceptron (MLP) based neural network. All the classifiers, the best accuracy of 91.84 ± 0.04% is shown to be of MLP-based neural network and this is 6% better over previously published. Further we observed that as MRR decreases, the system robustness increases and validated by standard deviations. The overall text system accuracy using all data types, classifiers, protocols is 89%, thereby showing the entire ML system to be novel, robust and unique. The system is also tested for stability and reliability.

NaI(Tl) and PMT scintillation detector of radioactive materials can be divided. Environmental radiation measurements using a semiconductor with SiPM detector PMT to replace the value of the results were compared. SiPM detector using radiation environment were measured in the field to verify the accuracy and energy resolution. SiPMs performance as environmental radiation measurement equipment and radioactive material distinction as a personal dosimeter based technology, using the above results were prepared. The interest on the environmental radiation due to the Fukushima power plant crisis in Japan has been growing concern about the radiation environment of the relatively close proximity Korea is a very heightened state.

    Our study aimed to assess Turkish publications in Science Citation Index (SCI) and Science Citation Index Expanded (SCI-E) indexed journals in the field of 'anaesthesiology'. Journals related to 'anaesthesiology' in the Science Citation Index-Expanded database of 'Thomson Reuter Web of Science' were searched. The search engine of Institute for Scientific Information (ISI) Web of Science (WoS) was used in the advanced mode by typing 'IS=ISSN number' to identify publications in the journal. By typing 'IS=ISSN number AND CU=Turkey', Turkish papers on anaesthesiology were found. If Turkish and non-Turkish authors had collaborated, the article was included in the search when the corresponding author had provided a Turkey-based address. The catalogue information and statistics were used to determine Turkish publications as the percentage of total publications and the annual mean number of Turkish publications. In WoS, 'SU=anesthesiology' was used to determine the number, country, year and topic distributions of publications from 1975 to date and within the last 10 years. The citation numbers and h-indices were determined based on the country for publications within the last 10 years. From 1975 to the early 2000s Turkey was 20 th in the list of countries with highest number of publications on anaesthesiology, however in the last 10 years Turkey moved up to 18 th place. Its mean citation number has been 4.64, and it remains the 2 nd lowest country pertaining to citations among the 22 countries with the most number of publications. According to the percentage of publications in the field of anaesthesiology, the journals with highest rate of Turkish publications were Revista Brasileira de Anestesiologia, European Journal of Anaesthesiology and Journal of Anesthesia. In the field of anaesthesiology, the highest number of articles from Turkey was published in Revista Brasileira de Anestesiologia, European Journal of Anaesthesiology and Journal of Anesthesia.

    Full Text Available The main purpose of the article is to analyze how effectively different types of thesaurus relations can be used for solutions of text classification tasks. The basis of the study is an automatically generated thesaurus of a subject area, that contains three types of relations: synonymous, hierarchical and associative. To generate the thesaurus the authors use a hybrid method based on several linguistic and statistical algorithms for extraction of semantic relations. The method allows to create a thesaurus with a sufficiently large number of terms and relations among them. The authors consider two problems: topical text classification and sentiment classification of large newspaper articles. To solve them, the authors developed two approaches that complement standard algorithms with a procedure that take into account thesaurus relations to determine semantic features of texts. The approach to topical classification includes the standard unsupervised BM25 algorithm and the procedure, that take into account synonymous and hierarchical relations of the thesaurus of the subject area. The approach to sentiment classification consists of two steps. At the first step, a thesaurus is created, whose terms weight polarities are calculated depending on the term occurrences in the training set or on the weights of related thesaurus terms. At the second step, the thesaurus is used to compute the features of words from texts and to classify texts by the algorithm SVM or Naive Bayes. In experiments with text corpora BBCSport, Reuters, PubMed and the corpus of articles about American immigrants, the authors varied the types of thesaurus relations that are involved in the classification and the degree of their use. The results of the experiments make it possible to evaluate the efficiency of the application of thesaurus relations for classification of raw texts and to determine under what conditions certain relationships affect more or less. In particular, the

    The synthetic aggregation pheromone of the large milkweed bug, Oncopeltus fasciatus (Dallas) (Lygaeinae), also attracted males of the plant bug, Phytocoris difficilis Knight (Miridae). Field testing partial blends against the six-component blend comprising the Oncopeltus pheromone showed that cross-attraction of P. difficilis males was due to synergism between (E)-2-octenyl acetate and (E,E)-2,4-hexadienyl acetate. Hexyl acetate was abundant in the metathoracic scent gland (MSG) secretion of P. difficilis males, but because female P. difficilis could not initially be found in the field, further combinatorial tests were guided by prior research on the pheromones of two Phytocoris species in the western United States. The combination of hexyl, (E)-2-hexenyl, and (E)-2-octenyl acetates was as attractive to P. difficilis males as the milkweed bug pheromone, yet no milkweed bugs were drawn to this blend. Gas chromatographic (GC)-electroantennographic detection (EAD) and GC-mass spectrometric (MS) analyses of female P. difficilis MSGs determined that their secretion contained predominantly hexyl, (E)-2-hexenyl, and (E)-2-octenyl acetates (all strongly EAD-active)-the latter two compounds found only in trace amounts from males-plus five minor female-specific compounds, three of which were EAD-active. (E,E)-2,4-Hexadienyl acetate was not detected from P. difficilis females or males. The blend of the three major components, hexyl, (E)-2-hexenyl, and (E)-2-octenyl acetates (2:1.5:1 by volume), was as attractive as the blend of all six EAD-active compounds identified from females, indicating that this ternary blend constitutes the sex pheromone of P. difficilis. Hexyl acetate with (E)-2-octenyl acetate also attracted males of another species, P. breviusculus Reuter, but addition of (E)-2-hexenyl acetate and/or (E,E)-2,4-hexadienyl acetate inhibited attraction of P. breviusculus males. Attraction of P. difficilis males occurred mainly during the first half of scotophase. The

    Even though citation analysis has several limitations, it is a commonly used tool to determine the impact of scientific articles in different research fields. The study aims to identify and systematically review the 100 most cited articles in the field of visceral surgery focusing on papers that modified therapeutic concepts and influenced the surgeons' decision making. The 100 most cited clinical articles in visceral surgery were identified using Journal Citation Reports and Science Citation Index Expanded of the Web of Science (Thomson Reuters, Philadelphia, Pa., USA). Data for characterization of the articles were determined: Number of citations, research topic, journal, publication time, authorship, country of origin, type of article and level of evidence if reasonable. The 100 most cited articles were published in 17 journals; 72 articles were found in the 3 journals: New England Journal of Medicine (38), Annals of Surgery (21) and Lancet (13). The oldest article was published in 1908 in Annals of Surgery (ranked 76th) and the most recent in 2012 in Lancet (65th). Eighty articles were published between 1990 and 2010. The number of citations ranged from 667 to 4,666 (median 925). The leading country of origin was the United States with 39 articles, followed by articles originating from more than one country (30). There were 45 interventional studies (27 randomized controlled trials), 32 observational studies, 19 reviews and 4 guidelines, definitions or classifications. The level of evidence was low (IV) in 42 articles and high in 35 articles (Ia or Ib). A high number of citations did not reflect a high level of evidence. The topics and research questions of the identified articles covered a large area of visceral surgery. Some of the milestones in visceral surgery were identified. The high impact measured by citations did not reflect a high quality of research (level of evidence) in a considerable number of publications. © 2016 S. Karger AG, Basel.

    The activity analysis of a scientific journal is relevant to know the evolution of its characteristics over time. In this paper, results of a bibliometric study of the Revista de Biología Tropical/International Journal of Tropical Biology and Conservation (Costa Rica) are presented. The goal of this study was to describe the main characteristics of its scientific production, and analyze its level of collaboration and its impact between the years 2003-2012. Data was derived from the Web of Science (Thomson-Reuters), and the relationship among authors and coauthors, institutions and countries, and their links with the citations received were analyzed for that period. Descriptive statistics about production (number of documents per year, institution and country), collaboration (authorship index, collaboration among institutions and countries) and impact (IF, position in JCR and number of citations received) were collected. Results showed that the journal has published 1 473 papers in this period, in similar proportions English and Spanish. Mexico, Costa Rica, Venezuela and Colombia are the most common countries of origin, with the Universidad of Costa Rica, Universidad Autónoma de Mexico and the University of Puerto Rico as the most common leader institutions. Collaboration between authors, institutions and countries has shown an increasing trend over the last decade. The co-author index was 3.07 per document, 63 % of publications included 2 or more institutions, and 22 % of the papers were product of international collaboration. The most common collaboration link was between Costa Rica and the United States of America. The impact factor has been oscillating during this last decade, reaching a maximum in 2012 (IF JCR = 0.553). Besides, 10 % of the most cited papers concentrated half of the citations received by the journal, and have a very high number of citations, compared with the journal mean. The main countries that cite the journal were USA, Brazil, Mexico

    Full Text Available CONTEXTO: O estabelecimento de biomarcadores relacionados à terapia cognitivo-comportamental (TCC é uma maneira de consolidar a eficácia do tratamento de forma mais objetiva, sendo crítico para o avanço desse campo de pesquisa. OBJETIVOS: Foi realizada uma revisão sistemática de estudos que: 1 utilizaram parâmetros biológicos para verificar a eficácia da TCC no tratamento do transtorno de estresse pós-traumático (TEPT; e 2 utilizaram esses parâmetros como preditores de resposta à CBT. MÉTODOS: Foram conduzidas buscas eletrônicas nas bases PubMed/Medline, ISI/Thompson Reuters e Pilot. RESULTADOS: Doze artigos foram selecionados para esta revisão, sendo quatro deles estudos sobre predição de resposta ao tratamento. Foi observada relação entre a eficácia da TCC e modificações nesses parâmetros, sendo a resposta da frequência cardíaca à evocação de sintomas o parâmetro mais utilizado até o presente momento. Sua redução está associada à melhora nos sintomas de TEPT. Potenciais biomarcadores de predição de resposta encontrados incluem 5α-redutase, ativação da amígdala, ativação e volume do córtex cingulado anterior e frequência cardíaca. CONCLUSÃO: Apesar da escassez de estudos e das limitações metodológicas neles observadas, investigações iniciais sugerem que os biomarcadores da TCC em pacientes com TEPT poderão ser úteis para o monitoramento mais objetivo dos efeitos do tratamento, identificação de predição de resposta e para o desenvolvimento de estratégias mais eficazes de tratamento e prevenção do desenvolvimento de TEPT.

    As research in Earth Science becomes more data intensive, a critical requirement of data archives is that data needs to be easily discovered, accessed, and used. One approach to improving data discovery and access is through data citations coupled with Digital Object Identifiers (DOI). Beginning in 1998, the Oak Ridge National Laboratory Distributed Active Archive Center (ORNL DAAC) has issued data product citations that have been accepted and used in AGU and other peer-reviewed journals. Citation elements established by the ORNL DAAC are similar to those used for journal articles (authors, titles, information to locate, and version), and beginning in 2007 included a DOI that is persistent, actionable, specific, and complete. The citation approach used at the DAAC also allows for referring to specific subsets of the data, by including within the citation the temporal and spatial portions of the data actually used. Citations allow others to find data and reproduce the results of the research article, and also use those data to test new hypotheses, design new sample collections, or construct or evaluate models. In addition to enhancing discovery and access of the data used in a research article, the citation gives credit to data generators, data centers and their funders, and, through citation indices, determine the scientific impact of a data set. The ORNL DAAC has developed a database that links research articles and their use of ORNL DAAC data products. The database allows determination of who, in which journal, and how the data have been used, in a manner analogous to author citation indices. The ORNL DAAC has been an initial contributor to the Thomson Reuters Data Citation Index. In addition, research data products deposited at the ORNL DAAC are linked using DOIs to relevant articles in Elsevier journals available on ScienceDirect. The ultimate goal of this implementation is that citations to data products become a routine part of the scientific process.

    The European & Developing Countries Clinical Trials Partnership (EDCTP) is a partnership of European and sub-Saharan African countries that aims to accelerate the development of medical interventions against poverty-related diseases (PRDs). A bibliometric analysis was conducted to 1) measure research output from European and African researchers on PRDs, 2) describe collaboration patterns, and 3) assess the citation impact of clinical research funded by EDCTP. Disease-specific research publications were identified in Thomson Reuters Web of Science using search terms in titles, abstracts and keywords. Publication data, including citation counts, were extracted for 2003-2011. Analyses including output, share of global papers, normalised citation impact (NCI), and geographical distribution are presented. Data are presented as five-year moving averages. European EDCTP member countries accounted for ~33% of global research output in PRDs and sub-Saharan African countries for ~10% (2007-2011). Both regions contributed more to the global research output in malaria (43.4% and 22.2%, respectively). The overall number of PRD papers from sub-Saharan Africa increased markedly (>47%) since 2003, particularly for HIV/AIDS (102%) and tuberculosis (TB) (81%), and principally involving Southern and East Africa. For 2007-2011, European and sub-Saharan African research collaboration on PRDs was highly cited compared with the world average (NCI in brackets): HIV/AIDS 1.62 (NCI: 1.16), TB 2.11 (NCI: 1.06), malaria 1.81 (NCI: 1.22), and neglected infectious diseases 1.34 (NCI: 0.97). The NCI of EDCTP-funded papers for 2003-2011 was exceptionally high for HIV/AIDS (3.24), TB (4.08) and HIV/TB co-infection (5.10) compared with global research benchmarks (1.14, 1.05 and 1.35, respectively). The volume and citation impact of papers from sub-Saharan Africa has increased since 2003, as has collaborative research between Europe and sub-Saharan Africa. >90% of publications from EDCTP

    Charon, the largest satellite of Pluto, is a gray-colored icy world covered mostly in H2O ice, with spectral evidence for NH3, as previously reported (Cook et al. 2007, Astrophys. J. 663, 1406-1419 Merlin, et al. 2010, Icarus, 210, 930; Cook, et al. 2014, AAS/Division for Planetary Sciences Meeting Abstracts, 46, #401.04). Images from the New Horizons spacecraft reveal a surface with terrains of widely different ages and a moderate degree of localized coloration. The presence of H2O ice in its crystalline form (Brown & Calvin 2000 Science 287, 107-109; Buie & Grundy 2000 Icarus 148, 324-339; Merlin et al, 2010) along with NH3 is consistent with a fresh surface.The phase of H2O ice is a key tracer of variations in temperature and physical conditions on the surface of outer Solar System objects. At Charon’s surface temperature H2O is expected to be amorphous, but ground-based observations (e.g., Merlin et al. 2010) show a clearly crystalline signature. From laboratory experiments it is known that amorphous H2O ice becomes crystalline at temperatures of ~130 K. Other mechanisms that can change the phase of the ice from amorphous to crystalline include micro-meteoritic bombardment (Porter et al. 2010, Icarus, 208, 492) or resurfacing processes such as cryovolcanism.New Horizons observed Charon with the LEISA imaging spectrometer, part of the Ralph instrument (Reuter, D.C., Stern, S.A., Scherrer, J., et al. 2008, Space Science Reviews, 140, 129). Making use of high spatial resolution (better than 10 km/px) and spectral resolving power of 240 in the wavelength range 1.25-2.5 µm, and 560 in the range 2.1-2.25 µm, we report on an analysis of the phase of H2O ice on parts of Charon’s surface with a view to investigate the recent history and evolution of this small but intriguing object.This work was supported by NASA’s New Horizons project.

    Introduction The Health of the Nation Outcome Scales (HoNOS) for adults, and equivalent measures for children and adolescents and older people, are widely used in clinical practice and research contexts to measure mental health and functional outcomes. Additional HoNOS measures have been developed for special populations and applications. Stakeholders require synthesised information about the measurement properties of these measures to assess whether they are fit for use with intended service settings and populations and to establish performance benchmarks. This planned systematic review will critically appraise evidence on the measurement properties of the HoNOS family of measures. Methods and analysis Journal articles meeting inclusion criteria will be identified via a search of seven electronic databases: MEDLINE via EBSCOhost, PsycINFO via APA PsycNET, Embase via Elsevier, Cumulative Index to Nursing and Allied Health Literature via EBSCOhost, Web of Science via Thomson Reuters, Google Scholar and the Cochrane Library. Variants of ‘Health of the Nation Outcome Scales’ or ‘HoNOS’ will be searched as text words. No restrictions will be placed on setting or language of publication.

    Full Text Available OBJECTIVES: This study aimed to compare the impact of Gross Domestic Product (GDP per capita, spending on Research and Development (R&D, number of universities, and Indexed Scientific Journals on total number of research documents (papers, citations per document and Hirsch index (H-index in various science and social science subjects among Asian countries. MATERIALS AND METHODS: In this study, 40 Asian countries were included. The information regarding Asian countries, their GDP per capita, spending on R&D, total number of universities and indexed scientific journals were collected. We recorded the bibliometric indicators, including total number of research documents, citations per document and H-index in various science and social sciences subjects during the period 1996-2011. The main sources for information were World Bank, SCI-mago/Scopus and Web of Science; Thomson Reuters. RESULTS: The mean per capita GDP for all the Asian countries is 14448.31±2854.40 US$, yearly per capita spending on R&D 0.64±0.16 US$, number of universities 72.37±18.32 and mean number of ISI indexed journal per country is 17.97±7.35. The mean of research documents published in various science and social science subjects among all the Asian countries during the period 1996-2011 is 158086.92±69204.09; citations per document 8.67±0.48; and H-index 122.8±19.21. Spending on R&D, number of universities and indexed journals have a positive correlation with number of published documents, citations per document and H-index in various science and social science subjects. However, there was no association between the per capita GDP and research outcomes. CONCLUSION: The Asian countries who spend more on R&D have a large number of universities and scientific indexed journals produced more in research outcomes including total number of research publication, citations per documents and H-index in various science and social science subjects.

Inclusion criteria were (1) patients with a history of enucleation or evisceration, (2) PSP, (3) report of the cause and/or used diagnostics and/or treatment modality, (4) full text in English, Dutch or Spanish language. Excluded were (1) review articles, (2) comments, and publications concerning, (3) nonhumans, (4) exenterated patients, (5) acute postoperative pain, or (6) periorbital pain without pain in the socket. Given the lack of high quality evidence from randomized controlled trials, we examined all available evidence from primary observational studies and assessed quality within this lower level of evidence. A total of 32 studies were included. Causes of PSP found were prosthesis-related (n = 5), dry socket (n = 2), trochleitis (n = 3), compression of the trigeminal nerve (n = 2), implant-related (n = unknown), inflammation (n = 5), surgery-related (n = 4), neuromas (n = 8), malignant tumours (n = 3), psychiatric/psychosocial (n = 2), phantom pain (n = 149), rarer entities (n = 3) or unknown (n = 14). Nonsurgical treatments suffice for conditions as trochleitis, prosthesis-related pain, dry socket and for phantom pain. Other causes of pain may require more invasive treatments such as implant removal. Careful history and examination can give some direction in the diagnostic procedure; however, PSP is probably multifactorial and the specific origin(s) may remain uncertain. Implant replacement can be an effective treatment. Studies to identifiy less invasive procedures are required. © 2018 Acta Ophthalmologica Scandinavica Foundation.

  17. Using the H Index to Assess Impact of DOE National Laboratories

    2016-05-13

    The most readily accessible elements of the Emerald Matrix by quantitative measures are the knowledge and economy related measures. In this paper, the H Index for an institution will be used to assess STE impact, which is in the knowledge generation element. The H Index was developed by Hirsch (2005) as a measure of an individual’s scientific impact. The H Index is defined as the number of publications that have been cited h or more times for a given author. It has been generalized to organizations. Doing so leads to a complication in that H index scales with the number of publications. Although this may not be problematic when comparing individual researchers, it systematically favors larger institutions. Molinari and Molinari (2008) proposed an alternative index (hm) designed to assess organizational impact. It transforms the H Index for an organization into an impact index by removing a factor dependent on the number of publications. The hm provides another approach to compare institutions provided that differences in the citation patterns associated with fields of study are addressed. Kinney (2007) used the Molinari and Molinari (2008) approach to compare various scientific institutions in nonbiomedical research areas. Kinney (2007) used the Thomson Reuters Web of Science (WoS) as the source and used publications in nonbiomedical research areas, which is very important because the research areas of universities are much broader than say a DOE national laboratory. Also there are differences in citation rates for the various research fields that make comparisons between individuals or organizations difficult. The results from Kinney (2007) are given in Table 1 and indicate that the DOE national laboratories compare favorably with the selected universities in terms of impact (hm) in the research areas used in Kinney’s analysis. This report will compare hm for DOE national laboratories using an approach similar to Kinney (2007) providing a measure of impact of

    Full Text Available If a doctoral dissertation represents an original investigation that makes a contribution to one's field, then dissertation research could, and arguably should, be disseminated into the scientific literature. However, the extent and nature of dissertation publication remains largely unknown within psychology. The present study investigated the peer-reviewed publication outcomes of psychology dissertation research in the United States. Additionally, we examined publication lag, scientific impact, and variations across subfields. To investigate these questions, we first drew a stratified random cohort sample of 910 psychology Ph.D. dissertations from ProQuest Dissertations & Theses. Next, we conducted comprehensive literature searches for peer-reviewed journal articles derived from these dissertations published 0-7 years thereafter. Published dissertation articles were coded for their bibliographic details, citation rates, and journal impact metrics. Results showed that only one-quarter (25.6% [95% CI: 23.0, 28.4] of dissertations were ultimately published in peer-reviewed journals, with significant variations across subfields (range: 10.1 to 59.4%. Rates of dissertation publication were lower in professional/applied subfields (e.g., clinical, counseling compared to research/academic subfields (e.g., experimental, cognitive. When dissertations were published, however, they often appeared in influential journals (e.g., Thomson Reuters Impact Factor M = 2.84 [2.45, 3.23], 5-year Impact Factor M = 3.49 [3.07, 3.90] and were cited numerous times (Web of Science citations per year M = 3.65 [2.88, 4.42]. Publication typically occurred within 2-3 years after the dissertation year. Overall, these results indicate that the large majority of Ph.D. dissertation research in psychology does not get disseminated into the peer-reviewed literature. The non-publication of dissertation research appears to be a systemic problem affecting both research and training

    A journal impact factor represents the mean number of citations per article published. Designed as one tool to measure the relative importance of a journal, impact factors are often incorporated into academic evaluation of investigators. The authors sought to determine how impact factors of emergency medicine (EM) journals compare to journals from other medical and surgical specialties and if any change has taken place over time. The 2010 impact factors and 5-year impact factors for each journal indexed by the Thomson Reuters ISI Web of Knowledge Journal Citation Reports (JCR) were collected, and EM, medical, and surgical specialties were evaluated. The maximum, median, and interquartile range (IQR) of the current impact factor and 5-year impact factor in each journal category were determined, and specialties were ranked according to the summary statistics. The "top three" impact factor journals for each specialty were analyzed, and growth trends from 2001 through 2010 were examined with random effects linear regression. Data from 2,287 journals in 31 specialties were examined. There were 23 EM journals with a current maximum impact factor of 4.177, median of 1.269, and IQR of 0.400 to 2.176. Of 23 EM journals, 57% had a 5-year impact factor available, with a maximum of 4.531, median of 1.325, and IQR of 0.741 to 2.435. The top three EM journals had a mean standard deviation (±SD) impact factor of 3.801 (±0.621) and median of 4.142 and a mean (±SD) 5-year impact factor of 3.788 (±1.091) and median of 4.297, with a growth trend of 0.211 (95% confidence interval [CI] = 0.177 to 0.245; p journals ranked no higher than 24th among 31 specialties. Emergency medicine journals rank low in impact factor summary statistics and growth trends among 31 medical and surgical specialties. © 2012 by the Society for Academic Emergency Medicine.

    2016-01-01

    Background Women are commonly prescribed a variety of medications during pregnancy. As most organ systems are affected by the substantial anatomical and physiological changes that occur during pregnancy, it is expected that pharmacokinetics (PK) (absorption, distribution, metabolism, and excretion of drugs) would also be affected in ways that may necessitate changes in dosing schedules. The objective of this study was to systematically identify existing clinically relevant evidence on PK changes during pregnancy. Methods and Findings Systematic searches were conducted in MEDLINE (Ovid), Embase (Ovid), Cochrane Central Register of Controlled Trials (Ovid), and Web of Science (Thomson Reuters), from database inception to August 31, 2015. An update of the search from September 1, 2015, to May 20, 2016, was performed, and relevant data were added to the present review. No language or date restrictions were applied. All publications of clinical PK studies involving a group of pregnant women with a comparison to nonpregnant participants or nonpregnant population data were eligible to be included in this review. A total of 198 studies involving 121 different medications fulfilled the inclusion criteria. In these studies, commonly investigated drug classes included antiretrovirals (54 studies), antiepileptic drugs (27 studies), antibiotics (23 studies), antimalarial drugs (22 studies), and cardiovascular drugs (17 studies). Overall, pregnancy-associated changes in PK parameters were often observed as consistent findings among many studies, particularly enhanced drug elimination and decreased exposure to total drugs (bound and unbound to plasma proteins) at a given dose. However, associated alterations in clinical responses and outcomes, or lack thereof, remain largely unknown. Conclusion This systematic review of pregnancy-associated PK changes identifies a significant gap between the accumulating knowledge of PK changes in pregnant women and our understanding of their

  2. Role of HIV-2 envelope in Lv2-mediated restriction

    We have characterized envelope protein pseudotyped HIV-2 particles derived from two HIV-2 isolates termed prCBL23 and CBL23 in order to define the role of the envelope protein for the Lv2-mediated restriction to infection. Previously, it has been described that the primary isolate prCBL23 is restricted to infection of several human cell types, whereas the T cell line adapted isolate CBL23 is not restricted in these cell types. Molecular cloning of the two isolates revealed that the env and the gag gene are responsible for the observed phenotype and that this restriction is mediated by Lv2, which is distinct from Ref1/Lv1 (Schmitz, C., Marchant, D., Neil, S.J., Aubin, K., Reuter, S., Dittmar, M.T., McKnight, A., Kizhatil, K., Albritton, L.M., 2004. Lv2, a novel postentry restriction, is mediated by both capsid and envelope. J. Virol. 78 (4), 2006-2016). We generated pseudotyped viruses consisting of HIV-2 (ROD-AΔenv-GFP, ROD-AΔenv-RFP, or ROD-AΔenv-REN) and the prCBL23 or CBL23 envelope proteins as well as chimeric proteins between these envelopes. We demonstrate that a single amino acid exchange at position 74 in the surface unit of CBL23-Env confers restriction to infection. This single point mutation causes tighter CD4 binding, resulting in a less efficient fusion into the cytosol of the restricted cell line. Prevention of endosome formation and prevention of endosome acidification enhance infectivity of the restricted particles for GHOST/X4 cells indicating a degradative lysosomal pathway as a cause for the reduced cytosolic entry. The described restriction to infection of the primary isolate prCBL23 is therefore largely caused by an entry defect. A remaining restriction to infection (19-fold) is preserved when endosomal acidification is prevented. This restriction to infection is also dependent on the presence of the point mutation at position 74 (G74E)

    This study aimed to compare the impact of Gross Domestic Product (GDP) per capita, spending on Research and Development (R&D), number of universities, and Indexed Scientific Journals on total number of research documents (papers), citations per document and Hirsch index (H-index) in various science and social science subjects among Asian countries. In this study, 40 Asian countries were included. The information regarding Asian countries, their GDP per capita, spending on R&D, total number of universities and indexed scientific journals were collected. We recorded the bibliometric indicators, including total number of research documents, citations per document and H-index in various science and social sciences subjects during the period 1996-2011. The main sources for information were World Bank, SCI-mago/Scopus and Web of Science; Thomson Reuters. The mean per capita GDP for all the Asian countries is 14448.31±2854.40 US$, yearly per capita spending on R&D 0.64±0.16 US$, number of universities 72.37±18.32 and mean number of ISI indexed journal per country is 17.97±7.35. The mean of research documents published in various science and social science subjects among all the Asian countries during the period 1996-2011 is 158086.92±69204.09; citations per document 8.67±0.48; and H-index 122.8±19.21. Spending on R&D, number of universities and indexed journals have a positive correlation with number of published documents, citations per document and H-index in various science and social science subjects. However, there was no association between the per capita GDP and research outcomes. The Asian countries who spend more on R&D have a large number of universities and scientific indexed journals produced more in research outcomes including total number of research publication, citations per documents and H-index in various science and social science subjects.

    The Mini Mental State Examination (MMSE) is a cognitive test that is commonly used as part of the evaluation for possible dementia. To determine the diagnostic accuracy of the Mini-Mental State Examination (MMSE) at various cut points for dementia in people aged 65 years and over in community and primary care settings who had not undergone prior testing for dementia. We searched the specialised register of the Cochrane Dementia and Cognitive Improvement Group, MEDLINE (OvidSP), EMBASE (OvidSP), PsycINFO (OvidSP), LILACS (BIREME), ALOIS, BIOSIS previews (Thomson Reuters Web of Science), and Web of Science Core Collection, including the Science Citation Index and the Conference Proceedings Citation Index (Thomson Reuters Web of Science). We also searched specialised sources of diagnostic test accuracy studies and reviews: MEDION (Universities of Maastricht and Leuven, www.mediondatabase.nl), DARE (Database of Abstracts of Reviews of Effects, via the Cochrane Library), HTA Database (Health Technology Assessment Database, via the Cochrane Library), and ARIF (University of Birmingham, UK, www.arif.bham.ac.uk). We attempted to locate possibly relevant but unpublished data by contacting researchers in this field. We first performed the searches in November 2012 and then fully updated them in May 2014. We did not apply any language or date restrictions to the electronic searches, and we did not use any methodological filters as a method to restrict the search overall. We included studies that compared the 11-item (maximum score 30) MMSE test (at any cut point) in people who had not undergone prior testing versus a commonly accepted clinical reference standard for all-cause dementia and subtypes (Alzheimer disease dementia, Lewy body dementia, vascular dementia, frontotemporal dementia). Clinical diagnosis included all-cause (unspecified) dementia, as defined by any version of the Diagnostic and Statistical Manual of Mental Disorders (DSM); International Classification of

    The purpose of this exploratory research was to study how students learn photosynthesis and cellular respiration and to determine the value added to the student's learning by each of the three technology-scaffolded learning strategy components (animated concept presentations and WebQuest-style activities, data collection, and student-constructed animations) of the BioDatamation(TM) (BDM) Program. BDM learning strategies utilized the Theory of Interacting Visual Fields(TM) (TIVF) (Reuter & Wandersee, 2002a, 2002b; 2003a, 2003b) which holds that meaningful knowledge is hierarchically constructed using the past, present, and future visual fields, with visual metacognitive components that are derived from the principles of Visual Behavior (Jones, 1995), Human Constructivist Theory (Mintzes & Wandersee, 1998a), and Visual Information Design Theory (Tufte, 1990, 1997, 2001). Student alternative conceptions of photosynthesis and cellular respiration were determined by the item analysis of 263,267 Biology Advanced Placement Examinations and were used to develop the BDM instructional strategy and interview questions. The subjects were 24 undergraduate students of high and low biology prior knowledge enrolled in an introductory-level General Biology course at a major research university in the Deep South. Fifteen participants received BDM instruction which included original and innovative learning materials and laboratories in 6 phases; 8 of the 15 participants were the subject of in depth, extended individual analysis. The other 9 participants received traditional, non-BDM instruction. Interviews which included participants' creation of concept maps and visual field diagrams were conducted after each phase. Various content analyses, including Chi's Verbal Analysis and quantitizing/qualitizing were used for data analysis. The total value added to integrative knowledge during BDM instruction with the three visual fields was an average increase of 56% for cellular respiration

    Spontaneous Hemoperitoneum in Pregnancy (SHiP), an unprovoked (nontraumatic) intraperitoneal bleeding in pregnancy (up to 42days postpartum), is associated with serious adverse pregnancy outcomes. To evaluate the clinical consequences of SHiP and its association with endometriosis, a systematic review was conducted according to the PRISMA guidelines. PubMed, Embase.com and Thomson Reuters/Web of Science were searched for articles published since the latest review (August 2008) until September 2016. After assessment for eligibility, forty-four articles were included in this systematic review, describing 59 cases of SHiP. Endometriosis was present in 33/59 cases (55.9%), most often diagnosed prior to pregnancy. An association between the severity of SHiP and the stage of endometriosis could not be found. In the majority of cases, SHiP occurred in the third trimester of pregnancy (30/59 cases (50.8%)); women presented with (sub)acute abdominal pain (56/59 cases (94.9%)), hypovolemic shock (28/59 cases (47.5%)) and/or a decreased level of hemoglobin (37/59 cases (62.7%)). Signs of fetal distress were observed in 24/59 cases (40.7%). Imaging confirmed free peritoneal fluid in (37/59 cases (62.7%)). At time of surgery active bleeding was revealed in 51/56 cases (91,1%), originating from endometriotic implants (11/51 cases (21.6%)), ruptured utero-ovarian vessels (29/51 cases (56.8%)), hemorrhagic nodules of decidualized cells (1/51 cases (2.0%)) or a combination (10/51 cases (19.6%)). Median amount of hemoperitoneum was 1600mL (IQR 1000mL-2500mL). From the 45/59 cases (76.3%) in which surgical interventions was carried out during pregnancy, 7/45 cases (15.6%) reported a successful continuation of pregnancy. 5/59 cases reported recurrence of SHiP (recurrence rate 8.5%). The perinatal mortality rate was 26.9% (18/67 fetus), one maternal death was reported (1/59 cases (1,7%)). In conclusion, SHiP is a very serious complication of pregnancy, highly associated with adverse

    The young surface of Pluto's Sputnik Planitia (SP) is one of the most prominent features observed by the New Horizon mission (Moore et al., 2016; Stern et al., 2015). No crater has been confirmed on the heart-shaped SP basin, in contrast to more than 5000 identified over comparable areas elsewhere (Robbins et al., 2016). The SP basin is filled with mostly N2 ice and small amount of CH4 and CO ice (Protopapa et al., 2017). Previous studies suggested that the SP surface might be renewed through vigorous thermal convection (McKinnon et al., 2016), and that the surface age may be as young as 500,000 years. In this paper, we present numerical simulations demonstrating that craters can be removed by rapid viscous relaxation of N2 ice over much shorter timescales. The crater retention age is less than 1000 years if the N2-ice thickness is several kilometers. McKinnon, W. B., Nimmo, F., Wong, T., Schenk, P. M., White, O. L., Roberts, J., . . . Umurhan, O.

    Full Text Available The high volatility combined with unpredictable fluctuations of CZK had shown one more time to the Czech exporting companies the necessity of currency hedging. This article is focused on finding of suitable currency hedging instrument for exporting company, working with the currency pair of CZK/EUR. In the first part, the time series analysis is made for volatility, interest rates and exchange rate. Based on the real market data – gained from Thomson REUTERS and CNB for the time period starting in 2002 – the detailed analysis is made in graphical form. The main goal is to find out the future trends with help of liner regression analysis, based on the historical data. Several graphs are provided with the trend line end estimated interval (min and max for the each variable. The calculated values are clearly marked, to be separated from the real market data. Exchange rate curve shows the market behaviour in the last years and is to be used as most important indicator for the future trends. Interest rates curves are very important for the calculation of the BIPS (basis points, determining the price of the forwards. The difference between landing and deposit rates for the same period of time and different currencies are showing the market estimation of the future development of each currency. Forward price is to be seen as a benchmark for the all other financial instruments. And finally the volatility (quoted as middle is very important part in the pricing of currency options.The second part is closely connected with the first one. Based on the results of provided analyses, it recommends a suitable hedging product for the next period of time. All of the analyses are taken as an input in different ways. The volatility is important for the decision of selling or purchasing the specific part of currency option. The exchange rate outlook together with the interest rates is the indicator of the future development of the currency pair and is playing

    Full Text Available It is a pleasure to write an editorial for the 6th issue of Veterinary Research Forum (VRF. Since its publication in June 2010, the journal has received a huge amount of welcome among the different walks of scientists and clinicians. On time publication, meticulous referring and quick processing of manuscripts are the attributes, which we pride on them all. Of course, all these would not have been achievable if we did not have your sincere co-operation. Thus, I will take this opportunity to extend my heartfelt gratitude, in equal measure, to the authors, reviewers, the editorial board, the editorial office and our readers. I am also extremely delighted to announce since the publication of previous issue, VRF has been added to the list of ISI (Institute of Scientific Information by Thomson Reuters Corporation. The same corporation which is also responsible for publishing Journal Citation Reports which lists an impact factor (IF for each of the journals that it tracks. This is a really big step forward for our new journal and we hope to obtain a deserved IF of our own in not very distant future.We have also recently teamed up with CABI, so at the moment full text content indexing of VRF have been started on CABI data bank, meaning more availability for a larger audience.In the current issue, we have included a review article titled “Nutrigenomics & Its Applications in Animal Science”. This review article may fall a little bit short from the strict standards, which are in place for a review article within our journal. However, due to rather new and burgeoning content of the paper we thought our readers might find it quite interesting, so we went ahead with its publication.Finally, we are thinking of designing a new more user-friendly, more reliable website for VRF which can include easy-to-use options for submission, review and tracking manuscripts for everyone. Thus, your suggestions and ideas will be very welcome in this regard.We are always

    The Accreditation Council for Graduate Medical Education (ACGME) requires orthopaedic residency programs to promote scholarship and research, which manifest differently among programs. We assess the impact of protected research time during orthopaedic residency on the number of resident publications. Rotation schedules and resident names were collected from 125 ACGME-accredited U.S. orthopaedic residency programs. Protected research time was classified as 1 of 3 types: (1) block time, (2) longitudinal time, or (3) no dedicated time. In April 2016, we searched residents in postgraduate year (PGY)-3 to PGY-5 on pubmed.gov to generate all orthopaedic publications with a PubMed identifier published during residency. Each publication's 2015 Thomson Reuters Journal Citation Reports 5-Year Journal Impact Factor and resident first authorship were noted. The number of PubMed identifiers for each program was summed and was divided by the number of residents in PGY-3 to PGY-5, giving a mean number of publications per resident. The relationship between output and program research time was compared using t tests and analysis of variance (ANOVA). A total of 1,690 residents were included, with an overall mean number (and standard deviation) of 1.2 ± 2.4 publications per resident. Eighty-seven programs reported block time, 14 programs reported longitudinal time, and 24 programs reported no time. There was a significant difference (p = 0.02) in the mean number of publications per resident when compared between programs with protected time (1.1 ± 1.2 publications) and programs with no protected time (0.6 ± 0.5 publication). One-way ANOVA demonstrated a significant mean difference across the 3 groups (p publications than block time at 1.0 ± 1.0 publication or no time at 0.6 ± 0.5 publication, a difference that persisted when adjusted to include only impact factors of >0 and exclude case reports (p = 0.0015).

    Full Text Available According to a worldwide well-known attitude, also in Italy, the assessment of scientific production in the last decades has been progressively based on the analysis of the impact through bibliometric variables. Various data sets, such as Scopus by Elsevier and Web of Science by Thomson Reuters, are designed and maintained to index a steadily increasing range of essays: mostly journal articles, book chapters, and conference proceedings. The indexing relays on the capacity to evaluate and update specific impact measures by keeping track of the citations representing the relations between the essays. The related opportunity to interpret bibliographic systems as research and development (R&D networks attracted the interest of scientists operating, beyond the field of bibliometric analysis, in the realm of social networking. Network analysis belongs to mechanical statistics and is able to make sense of interconnected systems including very large sets of nodes and links. In this paper, we present a network approach to the review of the scientific production in the time period January, 2003-June, 2016 of Italian agricultural engineers, namely scientists belonging to the Italian ministerial scientific disciplinary sector AGR/10 - rural buildings and agro-forestry territory. Starting from 238 articles indexed in the Web of Knowledge database and published by 87 AGR/10 scholars, we apply four network analysis approaches to the study of the citations among articles, the most influential journals and topics, the co-authorship, the most favourite keywords with their evolution in time, and the communities’ pattern. We discover that Italian agricultural engineers are interlaced in a sparse network with a still limited tendency toward citing each other and are inclined to team up in established research groups based on a single university. As for the dualism between rural buildings and territory, we document on a relevant expansion of the issues related to

    Necrotizing enterocolitis (NEC) is one of the most common acute and fatal gastrointestinal emergency in very low birth weight (VLBW) preterm neonates with mortality range from 15 to 30%. NEC is likely due to multifactorial process such as oxidative injury, ischemic necrosis, and over-reactive inflammatory response to intestinal microbes. To evaluate the role of amino acid supplementation for reduction of neonatal NEC in preterm neonates. The literature search was done for various randomized control trial (RCT) by searching the Cochrane Central Register of Controlled Trials (CENTRAL), PubMed, EMBASE, Web of Science, Scopus, Index Copernicus, African Index Medicus (AIM), Thomson Reuters (ESCI), Chemical Abstracts Service (CAS) and other database. This review included 15 RCTs that fulfilled inclusion criteria. The total neonates enrolled in these different RCT are 3424 (amino acid group 1711 and control 1713). Almost all participating neonates were of VLBW or extremely low birth weight (ELBW). In two trials, birth weight was between 1500-2000 grams. The intervention was started within first few days after birth and continued up to 30th day of postnatal age in most of the trials. In two trials, intervention was continued up to 120th day of postnatal age. Arginine, glutamine and N-acetyl cysteine (NAC) were used at the dose of 1.5 mol/kg/day (261 mg/kg/day), 0.3 grams/kg/day and 16-32 mg/kg/day, respectively. Role of amino acid in the prevention of neonatal NEC is not exclusively supported by the current evidence. Only three studies were able to show reduction in the incidence of NEC with amino acid supplementation (arginine, glutamine), and the remaining studies did not report any positive effect. Amino acid supplementation was not associated with significant reduction in mortality due to any causes. However, arginine supplementation was associated with significant reduction in mortality due to NEC. Two studies on glutamine were reported significant reduction in

    Concerns about reproducibility and impact of research urge improvement initiatives. Current university ranking systems evaluate and compare universities on measures of academic and research performance. Although often useful for marketing purposes, the value of ranking systems when examining quality and outcomes is unclear. The purpose of this study was to evaluate usefulness of ranking systems and identify opportunities to support research quality and performance improvement. A systematic review of university ranking systems was conducted to investigate research performance and academic quality measures. Eligibility requirements included: inclusion of at least 100 doctoral granting institutions, be currently produced on an ongoing basis and include both global and US universities, publish rank calculation methodology in English and independently calculate ranks. Ranking systems must also include some measures of research outcomes. Indicators were abstracted and contrasted with basic quality improvement requirements. Exploration of aggregation methods, validity of research and academic quality indicators, and suitability for quality improvement within ranking systems were also conducted. A total of 24 ranking systems were identified and 13 eligible ranking systems were evaluated. Six of the 13 rankings are 100% focused on research performance. For those reporting weighting, 76% of the total ranks are attributed to research indicators, with 24% attributed to academic or teaching quality. Seven systems rely on reputation surveys and/or faculty and alumni awards. Rankings influence academic choice yet research performance measures are the most weighted indicators. There are no generally accepted academic quality indicators in ranking systems. No single ranking system provides a comprehensive evaluation of research and academic quality. Utilizing a combined approach of the Leiden, Thomson Reuters Most Innovative Universities, and the SCImago ranking systems may provide

    The number of citations a publication receives can be used to show its impact on a field of study. It may indicate the educational interest in a given population or underline a perceived or real educational gap. This article identifies and characterizes the 100 top cited publications in radiologic journals as of May 2013. All clinical radiologic journals listed by Thomson Reuters Journal Citation Reports in 2011 were identified. A total of 46 journals were identified, and all articles published within these journals were analyzed for citation counts. The top 100 highly cited articles were recorded. The most frequently cited radiologic articles appeared in 9 of the 46 journals. These included 59 articles in Radiology, 17 in Journal of Nuclear Medicine, 9 in the American Journal of Roentgenology, 5 in the British Journal of Radiology, 4 in Investigative Radiology, 2 in American Journal of Neuroradiology, 2 in European Radiology, 2 in Radiologic Clinics of North America, 1 in the Seminars in Nuclear Medicine, and 1 in Pediatric Radiology. The citation values ranged from 422 to 7506 with a mean of 751. Publication dates ranged from 1967 to 2006 with the 5-year period between 1986 and 1990 accounting for the largest percentage of articles. The most frequently studied radiologic modality was magnetic resonance imaging (MRI; 28 articles), followed by vascular/interventional (19 articles) and nuclear medicine (13 articles). The central nervous system was the most frequently studied organ system (22 articles), followed by mixed organ systems (14 articles) and liver (12 articles). The top cited articles in radiologic journals span a wide range of imaging modalities, subspecialties, and organ systems. Topics that occurred frequently in the top 100 cited articles included contrast and radiopharmaceutical characterization, MRI of motion, percutaneous radiofrequency ablation in the liver and percutaneous vertebroplasty. We present a methodology that uses citation analysis to

    Research in pharmacological science is vital to support the health needs of human beings. Measuring the research output provides information that forms the basis of strategic decisions. This study aimed to investigate the impact of Gross Domestic Product (GDP), spending on Research and Development (R&D), number of universities and scientific journals on research documents (papers), citable documents, citations per document and H-index in pharmacological science among Middle East countries. All the 16 Middle East countries were included in the study. The information regarding GDP, spending on R&D, total number of universities and indexed scientific journals were collected. We recorded the total number of research documents, citable documents, citations per document and H-index in pharmacological science during the period 1996-2011. The main sources for information were World Bank, Web of Science, Journal Citation Reports (Thomson Reuters) and SCI-mago/Scopus. The mean per capita GDP of all the Middle East countries is 18125.49±5386.28 US$, spending on R&D 0.63±0.28% of GDP in US$, number of universities 36.56±11.33 and mean ISI indexed journal are 8.25±3.93. The number of research documents published in pharmacological science among the Middle East countries during the period 1996-2011 is 1344.44±499.34; citable documents 1286.37±476.34; citations per document 7.62± 0.84; and H-index is 30.68±6.32. There was a positive correlation between spending on R&D and citations per documents (r = 0.56, p = 0.02), H-Index (r = 0.56, p = 0.02); number of universities and research documents (r = 0.72, p = 0.002), citable documents (r = 0.72, p = 0.001); ISI indexed journals and research documents (r = 0.88, p = 0.0001), citable documents (r = 0.88, p = 0.0001), H-Index (r = 0.67, p = 0.004). However, there was no correlation between the GDP per capita and research outcome in pharmacological science. There is a positive association between spending on R&D, number of

    The article presents the general idea of Air-Coupled Impact-Echo (ACIE) method which is one of the non-destructive testing (NDT) techniques used in the construction industry. One of the main advantages of the general Impact Echo (IE) method is that it is sufficient to access from one side to that of the structure which greatly facilitate research in the road facilities or places which are difficult to access and diagnose. The main purpose of the article is to present state-of-the-art related to ACIE method based on the publications available at Thomson Reuters Web of Science Core Collection database (WOS) with the further analysis of the mentioned methods. Deeper analysis was also performed for the newest publications published within last 3 years related to ACIE for investigation on the subject of main focus of the researchers and scientists to try to define possible regions where additional examination and work is necessary. One of the main conclusions that comes from the performed analysis is that ACIE methods can be widely used for performing NDT of concrete structures and can be performed faster than standard IE method thanks to the Air-coupled sensors. What is more, 92.3% of the analysed recent research described in publications connected with ACIE was performed in laboratories, and only 23.1% in-situ on real structures. This indicates that method requires further research to prepare test stand ready to perform analysis on real objects outside laboratory conditions. Moreover, algorithms that are used for data processing and later presentation in ACIE method are still being developed and there is no universal solution available for all kinds of the existing and possible to find defects, which indicates possible research area for further works. Authors are of the opinion that emerging ACIE method could be good opportunity for ND testing especially for concrete structures. Development and refinement of test stands that will allow to perform in-situ tests could

  4. Spectroscopy of Pluto, 380-930 Nm at Six Longitudes

    We have obtained spectra of the Pluto-Charon pair (unresolved) in the wavelength range 380-930 nm with resolution approx..450 at six roughly equally spaced longitudes. The data were taken in May and June, 2014, with the 4.2-m Isaac Newton Telescope at Roque de Los Muchachos Observatory in the Canary Islands, using the ACAM (auxiliary-port camera) in spectrometer mode, and using two solar analog stars. The new spectra clearly show absorption bands of solid CH4 at 620, 728, and 850-910 nm, which were known from earlier work. The 620-nm CH4 band is intrinsically very weak, and its appearance indicates a long optical path-length through the ice. This is especially true if it arises from CH4 dissolved in N2 ice. Earlier work (Owen et al. Science 261, 745, 1993) on the near-infrared spectrum of Pluto (1-2.5 microns) has shown that the CH4 bands are shifted to shorter wavelengths because the CH4 occurs as a solute in beta-phase crystalline N2. The optical path-length through the N2 crystals must be on the order of several cm to produce the N2 band observed at 2.15 microns. The new spectra exhibit a pronounced red slope across the entire wavelength range; the slope is variable with longitude, and differs in a small but significant way from that measured at comparable longitudes by Grundy & Fink (Icarus 124, 329, 1996) in their 15-year study of Pluto's spectrum (500-1000 nm). The new spectra will provide an independent means for calibrating the color filter bands on the Multispectral Visible Imaging Camera (MVIC) (Reuter et al. Space Sci. Rev. 140, 129, 2008) on the New Horizons spacecraft, which will encounter the Pluto-Charon system in mid-2015. They will also form the basis of modeling the spectrum of Pluto at different longitudes to help establish the nature of the non-ice component(s) of Pluto's surface. It is presumed that the non-ice component is the source of the yellow-red coloration of Pluto, which is known to be variable across the surface.

    This study aimed to assess the impact of the Gross Domestic Product (GDP), spending on Research and Development (R&D), the number of universities and scientific journals on the published research documents, citable documents, citations per document and H-index in environmental sciences in the Middle East countries. All the 16 Middle East countries were included in the study. Information regarding the GDP, spending on R&D, the total number of universities and indexed journals was collected. Total number of research documents (papers), citable documents, citations per document and H-index in environmental sciences during the period 1996-2011 was recorded. The study used the World Bank, SCI-mago/Scopus, Web of Science, Journal Citation Reports (Thomson Reuters) as the main sources of information. The mean GDP per capita of all the Middle East countries amounted to 18 125.49±5386.28 US$, spending on R&D was 0.63±0.28 US$, the number of universities equaled 36.56±11.33 and mean ISI indexed journals amounted to 8.25±3.93. The mean number of research documents published in environmental sciences in the Middle East countries during the period 1996-2011 was 2202.12±883.98; citable documents: 2156.87±865.09; citations per document: 8.74±0.73; and the H-index: 35.37±6.17. There was a positive correlation between the money spent on R&D and citations per documents (r = 0.6, p = 0.01), H-Index (r = 0.6, p = 0.01); the number of universities and a total of research documents (r = 0.65, p = 0.006), citable documents (r = 0.65, p = 0.006), H-Index (r = 0.50, p = 0.04), as well as ISI indexed journals and total research documents (r = 0.94, p = 0.0001), citable documents (r = 0.94, p = 0.0001), H-Index (r = 0.73, p = 0.001). The Middle East countries which spend more on R&D and which have a large number of universities and ISI indexed journals are likely to produce more significant volume of research papers in the field of environmental science.

    Full Text Available Financial products and financial derivatives transactions are on front page in the profile publications, because they have generated huge gains for a small part of market participants, and losses as well, sometimes followed by collapse even on the international financial institutions. Very common we can find in specialized media the hypothesis that the global instability was caused by derivative contracts and by the magnitude of these transactions, from the years preceding the crisis. Since they appeared in order to protect investors against various risks, we believe that the approach must have via derivative products is the ethical one. It is true that derivatives trades have grown very rapidly and have expanded from the commercial field (commodity derivatives to the capital market, but this was because the demand for such products was very high. Basically, the demand for financial derivatives products has validated their existence in the market. Derivative financial products are used by traders of financial intermediation companies, dealers, brokers, individual investors and corporations or governments. Precisely because of this large spectrum of users of financial derivatives, we can ask whether they should be used only by specialists in derivatives trading. Taken literally, the term derivative refers to a new product resulting from the modification of an existing product, but has different properties from the original product and from which it was derived (Business Dictionary 2012. But financially speaking, a derivative is a financial contract between two or more parts that comes from the future value of n reference asset (Reuters 2001, 17. Of course, in literature there are many definitions of the concept of financial derivative. If we were to build our own simple definition, we define financial derivatives as financial contracts based on an underlying asset whose price on the spot market determines its price. This is a very simple

    The most-cited papers (MCPs) are likely those that impressed researchers and had profound influence on clinical practice or future developments in the related scientific field. This study was conducted to explore a bibliometric approach to assess where the oncology-related MCPs have been published in. The source of the data presented in this study was provided by using the InCitesTM, Web of Science, Thomson Reuters Database (2013). It contained any journal indexed by ISI between 1979 and 2013. The term MCPs arbitrarily defined as equal or more than 100 citations. A total of 565 publications were cited equal or more than 100 times. They were published in 79 different journals (64 oncology, 12 medicine, and 3 science), led by the Journal of Clinical Oncology (n = 76; 13.5%) and Cancer Research (n = 66; 11.7%) followed by Oncogene (n = 46; 8.1%), Nature Reviews Cancer (n = 41; 7.3%), and Cancer (n = 37; 6.5%). Moreover, the journal categories with the MCPs were the Oncology with 495 articles (87.6%), followed by the Medicine with 60 (10.6%) articles. However, the numbers of journals related to Science (n = 10; 1.8%) were the least. The MCPs were cited a total of 118,531 times. The citations ranged from 100 to 1,790, and the median number was 149. The total numbers of MCPs were the most prominent for the journals, the New England Journal of Medicine (median 398), Lancet (median 213), and Nature Reviews Cancer (median 210). In other side, the counts of MCPs were the highest for the Science and Medicine-categorized journals (median 212.5 and 192.5 citations, respectively). The MCPs categorized as Oncology were the least cited (median 145). The median number of MCPs per year was 18.7 with range 4.1-858.5. The annual most valuable MCPs were also published in the journal Nature Reviews Cancer (median 42) and the New England Journal of Medicine (median 38.7). Likewise, the numbers of MCPs were the highest for the Science-categorized journals (median

    This paper explores the use of machine learning and Bayesian classification models to develop broadly applicable risk stratification models to guide disease management of health plan enrollees with substance use disorder (SUD). While the high costs and morbidities associated with SUD are understood by payers, who manage it through utilization review, acute interventions, coverage and cost limitations, and disease management, the literature shows mixed results for these modalities in improving patient outcomes and controlling cost. Our objective is to evaluate the potential of data mining methods to identify novel risk factors for chronic disease and stratification of enrollee utilization, which can be used to develop new methods for targeting disease management services to maximize benefits to both enrollees and payers. For our evaluation, we used DecisionQ machine learning algorithms to build Bayesian network models of a representative sample of data licensed from Thomson-Reuters' MarketScan consisting of 185,322 enrollees with three full-year claim records. Data sets were prepared, and a stepwise learning process was used to train a series of Bayesian belief networks (BBNs). The BBNs were validated using a 10 percent holdout set. The networks were highly predictive, with the risk-stratification BBNs producing area under the curve (AUC) for SUD positive of 0.948 (95 percent confidence interval [CI], 0.944-0.951) and 0.736 (95 percent CI, 0.721-0.752), respectively, and SUD negative of 0.951 (95 percent CI, 0.947-0.954) and 0.738 (95 percent CI, 0.727-0.750), respectively. The cost estimation models produced area under the curve ranging from 0.72 (95 percent CI, 0.708-0.731) to 0.961 (95 percent CI, 0.95-0.971). We were able to successfully model a large, heterogeneous population of commercial enrollees, applying state-of-the-art machine learning technology to develop complex and accurate multivariate models that support near-real-time scoring of novel payer

    PANGAEA® (Data Publisher for Earth & Environmental Science) is an information system which represents the ideal functioning of the ICSU World Data System. Storing about half a million data sets from all fields of geosciences it belongs to the largest archives for observational data. Standard conform interfaces (ISO, OGC, W3C, OAI) enable access from a variety of data and information portals, among them the search engine of PANGAEA® itself (www.pangaea.de) and e.g. large portals like Thomson Reuter's Web of Knowledge and Google. All data sets in PANGAEA® are citable, fully documented, and can be referenced via persistent identifier (Digital Object Identifier - DOI) - a premise for data publication. Together with other ICSU World Data Centers and the Technical Information Library in Germany(TIB) PANGAEA® had a share in the implementation of a DOI based registry for scientific data, which by now is supported by a worldwide consortium of libraries (www.datacite.org). The long term goal is a "crossref for scientific data". Seeing the overall positive impact on the quality and availability of scientific data the PANGAEA® group is offering publication services since several years. They were the main initiators of the "Earth System Science Journal" at Copernicus (http://earth-system-science-data.net/), which is used for standalone peer reviewed data publications. A further milestone was building up strong co-operations with commercial publishers as Elsevier, Nature, Springer, Wiley, AGU, and others. A common web service allows to reference related data in PANGAEA® directly from an articles' abstract page (e.g. ScienceDirect). The next step with commercial publishers is to further integrate the editorial process for the publication of related data with the publication procedures on the journal side, which practically means an extension of the peer review and a synchronization of editorial processes. In this presentation we will introduce the auditorium with the data

    A deficiency in vitamin K has been associated with increased calcium deposition and coronary artery calcification, which may lead to cardiovascular disease. To determine the effectiveness of vitamin K supplementation as a single nutrient supplement for the primary prevention of cardiovascular disease. We searched the following electronic databases: the Cochrane Central Register of Controlled Trials (CENTRAL, Issue 8 of 12, 2014); MEDLINE (Ovid, 1946 to September week 2 2014); EMBASE Classic + EMBASE (Ovid, 1947 to September 18 2014); Science Citation Index Expanded (SCI-EXPANDED) and Conference Proceedings Citation Index, Science (CPCI-S) (both 1990 to 17 September 2014) on Web of Science (Thomson Reuters); Database of Abstracts of Reviews of Effects (DARE); Health Technology Assessment Database and Health Economics Evaluations Database (Issue 3 of 4, 2014). We searched trial registers and reference lists of reviews for further studies. We applied no language restrictions. We included randomised controlled trials of vitamin K supplementation as a single nutrient supplement, lasting at least three months, and involving healthy adults or adults at high risk of cardiovascular disease. The comparison group was no intervention or placebo. The outcomes of interest were cardiovascular disease clinical events and cardiovascular disease risk factors. Two review authors independently selected trials for inclusion, abstracted the data and assessed the risk of bias. We included only one small trial (60 participants randomised) which overall was judged to be at low risk of bias. The study examined two doses of menaquinone (vitamin K2) over 3 months in healthy participants aged 40 to 65 years. The primary focus of the trial was to examine the effects of menaquinone (subtype MK7) on different matrix Gla proteins (MGP - vitamin K dependent proteins in the vessel wall) at different doses, but the authors also reported blood pressure and lipid levels. The trial did not report on our

    We have analyzed infrared spectra of Titan recorded by the Cassini Composite Infrared Spectrometer (CIRS) to measure the isotopic ratio 12C/ 13C in each of three chemical species in Titan's stratosphere: CH 4, C 2H 2 and C 2H 6. This is the first measurement of 12C/ 13C in any C 2 molecule on Titan, and the first measurement of 12CH 4/ 13CH 4 (non-deuterated) on Titan by remote sensing. Our spectra cover five widely-spaced latitudes, 65° S to 71° N and we have searched for both latitude variability of 12C/ 13C within a given species, and also for differences between the 12C/ 13C in the three gases. For CH 4 alone, we find C12/C13=76.6±2.7 (1- σ), essentially in agreement with the 12CH 4/ 13CH 4 measured by the Huygens Gas Chromatograph/Mass Spectrometer instrument (GCMS) [Niemann, H.B., and 17 colleagues, 2005. Nature 438, 779-784]: 82.3±1.0, and also with measured values in H 13CN and 13CH 3D by CIRS at lower precision [Bézard, B., Nixon, C., Kleiner, I., Jennings, D., 2007. Icarus 191, 397-400; Vinatier, S., Bézard, B., Nixon, C., 2007. Icarus 191, 712-721]. For the C 2 species, we find C12/C13=84.8±3.2 in C 2H 2 and 89.8±7.3 in C 2H 6, a possible trend of increasingly value with molecular mass, although these values are both compatible with the Huygens GCMS value to within error bars. There are no convincing trends in latitude. Combining all fifteen measurements, we obtain a value of C12/C13=80.8±2.0, also compatible with GCMS. Therefore, the evidence is mounting that 12C/ 13C is some 8% lower on Titan than on the Earth (88.9, inorganic standard), and lower than typical for the outer planets ( 88±7 [Sada, P.V., McCabe, G.H., Bjoraker, G.L., Jennings, D.E., Reuter, D.C., 1996. Astrophys. J. 472, 903-907]). There is no current model for this enrichment, and we discuss several mechanisms that may be at work.

Methods A total of 300, 1-d-old healthy broiler chickens were randomly divided into five treatment groups: i basal diet (control, ii basal diet+0.25% yeast (Saccharomyces cerevisiae (YC, iii basal diet+0.25% yeast with bacteriocin (BA, iv basal diet+Lactobacillus cultures (LAB, and v basal diet +0.25% yeast with bacteriocin+Lactobacillus cultures (BA+LAB. Growth performance, cecal microbiota, cecal fermentation products, and blood biochemistry parameters were determined when chickens were 21 and 35 d old. Results The supplementation of YC, BA, and BA+LAB resulted in a significantly better feed conversion rate (FCR than that of the control group during 1 to 21 d (p<0.05. The LAB supplementation had a significant effect on the presence of Lactobacillus in the ceca at 35 d. None of the supplements had an effect on relative numbers of L. agilis and L. reuter at 21 d, but the BA supplementation resulted in the decrease of both Lactobacillus strains at 35 d. The BA+LAB supplementation resulted in higher short chain fatty acid (SCFA in the ceca, but LAB supplementation significantly decreased the SCFA at 35 d (p<0.05. All treatments tended to decrease ammonia concentration in the ceca at 21 d, especially in the LAB treatment group. The BA supplementation alone decreased the triacylglycerol (TG concentration significantly at 21 d (p<0.05, but the synergistic effect of BA and LAB supplementation was required to reduce the TG concentration at 35 d. The YC supplementation tended to increase the plasma cholesterol at 21 d and 35 d. However, the BA supplementation significantly decreased the cholesterol and low density lipoprotein cholesterol level at 35 d. In conclusion, the BA

    Full Text Available Abstract Background Patients with rheumatoid arthritis (RA are known to be at increased risk of infection, particularly if they are taking drugs with immunomodulatory effects. There is a need for more information on the risk of influenza in patients with RA. Methods A retrospective cohort study was carried out using data gathered from a large US commercial health insurance database (Thomson Reuters Medstat MarketScan from 1 January 2000 to 31 December 2007. Patients were ≥18 years of age, with at least two RA claims diagnoses. The database was scanned for incidence of seasonal influenza and its complications on or up to 30 days after an influenza diagnosis in RA patients and matched controls. Other factors accounted for included medical conditions, use of disease-modifying anti-rheumatic drugs (DMARDs, use of biological agents, influenza vaccination and high- or low-dose corticosteroids. Incidence rate ratios (IRRs were calculated for influenza and its complications in patients with RA. Results 46,030 patients with RA and a matching number of controls had a median age of 57 years. The incidence of influenza was higher in RA patients than in controls (409.33 vs 306.12 cases per 100,000 patient-years, and there was a 2.75-fold increase in incidence of complications in RA. Presence or absence of DMARDs or biologics had no significant effect. The adjusted IRR of influenza was statistically significant in patients aged 60–69 years, and especially among men. A significantly increased rate of influenza complications was observed in women and in both genders combined (but not in men only when all age groups were combined. In general, the risk of influenza complications was similar in RA patients not receiving DMARDs or biologics to that in all RA patients. Pneumonia rates were significantly higher in women with RA. Rates of stroke/myocardial infarction (MI were higher in men, although statistical significance was borderline. Conclusions RA is

It results from chronic inflammation and causes irreversible airway damage. Levels of different serum cytokines could be surrogate biomarkers for inflammation and lung function in COPD. We aimed to determine the serum levels of different biomarkers in COPD patients, the association between cytokine levels and various prognostic parameters, and the key pathways/networks involved in stable COPD. In this study, serum levels of 48 cytokines were examined by multiplex assays in 30 subjects (control, n=9; COPD, n=21. Relationships between serum biomarkers and forced expiratory volume in 1 second, peak oxygen uptake, body mass index, dyspnea score, and smoking were assessed. Enrichment pathways and networks analyses were implemented, using a list of cytokines showing differential expression between healthy controls and patients with COPD by Cytoscape and GeneGo Metacore™ softwares (Thomson-Reuters Corporation, New York, NY, USA. Concentrations of cutaneous T-cell attracting chemokine, eotaxin, hepatocyte growth factor, interleukin 6 (IL-6, IL-16, and stem cell factor are significantly higher in COPD patients compared with in control patients. Notably, this study identifies stem cell factor as a biomarker for COPD. Multiple regression analysis predicts that cutaneous T

The world periodicals are developed in two levels, parts of the World System of Abstracting, Indexing and Evaluation, WSAIE. This system is just the body of the world science. The first level consists of the primary research journals. After careful inspection these journals should be accepted for covering in secondary research sources; the latter build the second level of the system. Journals, which are not presented in secondary research sources, are considered as marginal and the submission of manuscripts to such journals is not recommended. The second level of WSAIE has an elite part, an American one (Thomson Reuters, Web of Science, and an European one (Elsevier, SCOPUS. The journals of Web of Science are characterized by their impact factor, IF; the journals of SCOPUS are characterized by their im-pact rank, SJR; these journals' scientometric characteristics are entirely equal in use; no one of them should be favoured in respect to the other. However, these factors characterize the journals, not authors publishing in them; there-fore, these numbers cannot be used neither to compare different scientific areas nor in the personal evaluation of authors' scientific activity. The personal and institutional competencies for research could be estimated by properly use of some scientometric variables. The most important of them are considered. Amongst them are the index of Hirsch, h, and the factor of efficiency, e. In twenty-first century a new development of science began.

    Society always has limited resources to expend on health care, or anything else. What are the unmet medical needs? How do we allocate limited resources to maximize the health and welfare of the people? These challenging questions might be re-examined systematically within an infodemiological frame on a much larger scale, leveraging the latest advancement in information technology and data science. We expanded our previous work by investigating news media data to reveal the coverage of different diseases and medical conditions, together with their sentiments and topics in news articles over three decades. We were motivated to do so since news media plays a significant role in politics and affects the public policy making. We analyzed over 3.5 million archive news articles from Reuters media during the periods of 1996/1997, 2008 and 2016, using summary statistics, sentiment analysis, and topic modeling. Summary statistics illustrated the coverage of various diseases and medical conditions during the last 3 decades. Sentiment analysis and topic modeling helped us automatically detect the sentiments of news articles (ie, positive versus negative) and topics (ie, a series of keywords) associated with each disease over time. The percentages of news articles mentioning diseases and medical conditions were 0.44%, 0.57% and 0.81% in the three time periods, suggesting that news media or the public has gradually increased its interests in medicine since 1996. Certain diseases such as other malignant neoplasm (34%), other infectious diseases (20%), and influenza (11%) represented the most covered diseases. Two hundred and twenty-six diseases and medical conditions (97.8%) were found to have neutral or negative sentiments in the news articles. Using topic modeling, we identified meaningful topics on these diseases and medical conditions. For instance, the smoking theme appeared in the news articles on other malignant neoplasm only during 1996/1997. The topic phrases HIV and

    Sleeping Beauties (SBs) are publications that are scarcely cited in the years immediately following publication but then suddenly become highly cited later. Such publications have unique citation patterns and can reveal important developments in the field in which they appear. No holistic analysis of nursing SBs has been done yet. The aim of this study was to identify and analyze the SB phenomenon in the nursing research literature. The corpus for the nursing SB identification was harvested from the Web of Science Core Collection (Thomas Reuters) for the period 1934-2015. Citation histories of 212,239 publications were screened. From those, 3,209 publications with more than 100 citations were selected for analysis. We used our own software and applied the van Raan (2004) and Baumgartner (2010) criteria for SBs-a 5-year sleeping period with at most 10 citations during that time, an average of at least five citations per year after the first 10 years, with at least 100 citations in total. The knowledge context for SBs was determined using citing papers. All citing papers were analyzed with the help of VOSviewer software. Nine publications were identified as SBs (prevalence of 0.004%). The length of sleep duration ranged from 5 to 10 years (M = 6.8, SD = 2.0), depth of sleep ranged from 0.2 to 0.8 citations (M = 0.6, SD = 0.2), and awake intensity ranged from 6.4 to 15.0 citations (M = 11.0, SD = 3.8). The average number of citations to SBs was 229. Most nursing SBs were produced in the United States (n = 8) from top institutions in journals with high-impact factors. Nursing SBs covered topics including resilience, sampling in qualitative research, metasynthesis, postoperative pain in children, dementia rating scales, care of patients with Alzheimer's disease, nursing theory related to fatigue mechanisms in cancer patients, and family participation during resuscitation. Nursing SBs were cited by authors from a large number of institutions and countries; the number of

    Intensive care medicine is a medical specialty that was officially established in our country in 1978, with a 5-year training program including two years of common core training followed by three years of specific training in an intensive care unit accredited for training. During this 32-year period, intensive care medicine has carried out an intense and varied activity, which has allowed its positioning as an attractive and with future specialty in the hospital setting. This document summarizes the history of the specialty, its current situation, the key role played in the programs of organ donation and transplantation of the National Transplant Organization (after more than 20 years of mutual collaboration), its training activities with the development of the National Plan of Cardiopulmonary Resuscitation, with a trajectory of more than 25 years, its interest in providing care based on quality and safety programs for the severely ill patient. It also describes the development of reference registries due to the need for reliable data on the care process for the most prevalent diseases, such as ischemic heart disease or ICU-acquired infections, based on long-term experience (more than 15 years), which results in the availability of epidemiological information and characteristics of care that may affect the practical patient's care. Moreover, features of its scientific society (SEMICYUC) are reported, an organization that agglutinates the interests of more than 280 ICUs and more than 2700 intensivists, with reference to the journal Medicina Intensiva, the official journal of the society and the Panamerican and Iberian Federation of Critical Medicine and Intensive Care Societies. Medicina Intensiva is indexed in the Thompson Reuters products of Science Citation Index Expanded (Scisearch(®)) and Journal Citation Reports, Science Edition.

    Wind power is employed worldwide as an alternative source of energy. At the same time, however, the health effects of wind turbines have become a matter of discussion. The purpose of this study is a critical review of available reports providing arguments both for and against the construction of wind farms. The authors also attempt to propose recommendations in accordance with the Evidence-Based Medicine (EBM) guidelines. In the case of exposure to wind farms, a randomized controlled trial (RCT) is impossible. To obtain the highest-level recommendations, analysis of case-control studies or cohort studies with control groups should be performed. Preferably, it should include geostatistical analysis conducted with the use of variograms and the kriging technique. Combinations of key words were entered into the Thomson Reuters Web of Knowledge (SM) and the Internet search engine Google. SHORT DESCRIPTION OF STATE OF THE ART: The nuisance caused by wind turbines is stereotypically linked with the noise that they produce. Nevertheless, the visual aspect of wind farms, opinions about them, and sensitivity to sound seem to be of the greater importance. To date, the direct correlations between the vicinity of modern wind farms, the noise that wind turbines make, and possible consequences to health have not been described in peer reviewed articles. Health effects are more probably associated with some environmental factors leading to annoyance or frustration. All types of studies share the same conclusion: wind turbines can provoke annoyance. As with any project involving changes in the local environment, a certain level of irritation among the population can be expected. There are elected officials and government representatives who should decide what level of social annoyance is acceptable, and whether wind power advantages outweigh its potential drawbacks. The influence of wind turbines on human emotional and physical health is a relatively new field of research. Further

  3. Photovoltaic reciprocity and quasi-Fermi level splitting in nanostructure-based solar cells (Conference Presentation)

    The photovoltaic reciprocity theory relates the electroluminescence spectrum of a solar cell under applied bias to the external photovoltaic quantum efficiency of the device as measured at short circuit conditions [1]. So far, the theory has been verified for a wide range of devices and material systems and forms the basis of a growing number of luminesecence imaging techniques used in the characterization of photovoltaic materials, cells and modules [2-5]. However, there are also some examples where the theory fails, such as in the case of amorphous silicon. In our contribution, we critically assess the assumptions made in the derivation of the theory and compare its predictions with rigorous formal relations as well as numerical computations in the framework of a comprehensive quantum-kinetic theory of photovoltaics [6] as applied to ultra-thin absorber architectures [7]. One of the main applications of the photovoltaic reciprocity relation is the determination of quasi-Fermi level splittings (QFLS) in solar cells from the measurement of luminescence. In nanostructure-based photovoltaic architectures, the determination of QFLS is challenging, but instrumental to assess the performance potential of the concepts. Here, we use our quasi-Fermi level-free theory to investigate existence and size of QFLS in quantum well and quantum dot solar cells. [1] Uwe Rau.

    Introduction In a 2015 report, the Institute of Medicine (IOM; Washington, DC USA), now the National Academy of Medicine (NAM; Washington, DC USA), stated that the field of Emergency Medical Services (EMS) exhibits signs of fragmentation; an absence of system-wide coordination and planning; and a lack of federal, state, and local accountability. The NAM recommended clarifying what roles the federal government, state governments, and local communities play in the oversight and evaluation of EMS system performance, and how they may better work together to improve care. This systematic literature review and environmental scan addresses NAM's recommendations by answering two research questions: (1) what aspects of EMS systems are most measured in the peer-reviewed and grey literatures, and (2) what do these measures and studies suggest for high-quality EMS oversight? To answer these questions, a systematic literature review was conducted in the PubMed (National Center for Biotechnology Information, National Institutes of Health; Bethesda, Maryland USA), Web of Science (Thomson Reuters; New York, New York USA), SCOPUS (Elsevier; Amsterdam, Netherlands), and EMBASE (Elsevier; Amsterdam, Netherlands) databases for peer-reviewed literature and for grey literature; targeted web searches of 10 EMS-related government agencies and professional organizations were performed. Inclusion criteria required peer-reviewed literature to be published between 1966-2016 and grey literature to be published between 1996-2016. A total of 1,476 peer-reviewed titles were reviewed, 76 were retrieved for full-text review, and 58 were retained and coded in the qualitative software Dedoose (Manhattan Beach, California USA) using a codebook of themes. Categorizations of measure type and level of application were assigned to the extracted data. Targeted websites were systematically reviewed and 115 relevant grey literature documents were retrieved. A total of 58 peer-reviewed articles met inclusion

    Self-management is essential to caring for high-need, high-cost (HNHC) populations. Advances in mobile phone technology coupled with increased availability and adoption of health-focused mobile apps have made self-management more achievable, but the extent and quality of the literature supporting their use is not well defined. The purpose of this review was to assess the breadth, quality, bias, and types of outcomes measured in the literature supporting the use of apps targeting HNHC populations. Data sources included articles in PubMed and MEDLINE (National Center for Biotechnology Information), EMBASE (Elsevier), the Cochrane Central Register of Controlled Trials (EBSCO), Web of Science (Thomson Reuters), and the NTIS (National Technical Information Service) Bibliographic Database (EBSCO) published since 2008. We selected studies involving use of patient-facing iOS or Android mobile health apps. Extraction was performed by 1 reviewer; 40 randomly selected articles were evaluated by 2 reviewers to assess agreement. Our final analysis included 175 studies. The populations most commonly targeted by apps included patients with obesity, physical handicaps, diabetes, older age, and dementia. Only 30.3% (53/175) of the apps studied in the reviewed literature were identifiable and available to the public through app stores. Many of the studies were cross-sectional analyses (42.9%, 75/175), small (median number of participants=31, interquartile range 11.0-207.2, maximum 11,690), or performed by an app's developers (61.1%, 107/175). Of the 175 studies, only 36 (20.6%, 36/175) studies evaluated a clinical outcome. Most apps described in the literature could not be located on the iOS or Android app stores, and existing research does not robustly evaluate the potential of mobile apps. Whereas apps may be useful in patients with chronic conditions, data do not support this yet. Although we had 2-3 reviewers to screen and assess abstract eligibility, only 1 reviewer abstracted

  8. The role of high-frequency oscillations in epilepsy surgery planning.

    2017-10-05

    Epilepsy is a serious brain disorder characterized by recurrent unprovoked seizures. Approximately two-thirds of seizures can be controlled with antiepileptic medications (Kwan 2000). For some of the others, surgery can completely eliminate or significantly reduce the occurrence of disabling seizures. Localization of epileptogenic areas for resective surgery is far from perfect, and new tools are being investigated to more accurately localize the epileptogenic zone (the zone of the brain where the seizures begin) and improve the likelihood of freedom from postsurgical seizures. Recordings of pathological high-frequency oscillations (HFOs) may be one such tool. To assess the ability of HFOs to improve the outcomes of epilepsy surgery by helping to identify more accurately the epileptogenic areas of the brain. For the latest update, we searched the Cochrane Epilepsy Group Specialized Register (25 July 2016), the Cochrane Central Register of Controlled Trials (CENTRAL) via the Cochrane Register of Studies Online (CRSO, 25 July 2016), MEDLINE (Ovid, 1946 to 25 July 2016), CINAHL Plus (EBSCOhost, 25 July 2016), Web of Science (Thomson Reuters, 25 July 2016), ClinicalTrials.gov (25 July 2016), and the World Health Organization International Clinical Trials Registry Platform ICTRP (25 July 2016). We included studies that provided information on the outcomes of epilepsy surgery for at least six months and which used high-frequency oscillations in making decisions about epilepsy surgery. The primary outcome of the review was the Engel Class Outcome System (class I = no disabling seizures, II = rare disabling seizures, III = worthwhile improvement, IV = no worthwhile improvement). Secondary outcomes were responder rate, International League Against Epilepsy (ILAE) epilepsy surgery outcome, frequency of adverse events from any source and quality of life outcomes. We intended to analyse outcomes via an aggregated data fixed-effect model meta-analysis. Two studies representing

    Driving simulators are used in a wide range of research settings to help develop an understanding of driver behavior in complex environments. Acute alcohol impairment is an important research topic for traffic safety and a large number of studies have indicated levels of simulated driving impairment imposed by alcohol across a range of performance outcome variables. The aim of the present study was to examine the impact of acute alcohol consumption on simulated driving performance by conducting a systematic review and meta-analysis of the available evidence. The online databases PubMed (MEDLINE), Web of Science (via Thomas Reuters) and Scopus were searched to identify studies that measured simulated car driving performance under control ('no alcohol' or 'placebo alcohol' ingestion) and intervention (acute alcohol ingestion) conditions, using repeated-measures experimental designs. Primary research outcomes were standard deviation of lane position (SDLP) and standard deviation of speed (SDSP); (total number of lane crossings (LC) and average speed (Speed) were secondary research outcomes). Meta-analytic procedures were used to quantify the effect of acute alcohol consumption on vehicle control, and to determine the influence of methodological variables (i.e. the duration of the simulated driving task, the limb of the BAC curve (ascending vs. descending) and the type of driving simulator employed (i.e. car vs. PC-based)) on the magnitude of the performance change due to alcohol consumption. 423 records were screened, and 50 repeated-measures trials (n=962 participants, 62% male) derived from 17 original publications were reviewed. 37 trials (n=721 participants) used a 'placebo alcohol' comparator to determine the effect of alcohol consumption on SDLP (32/37) and SDSP (22/37). Alcohol consumption significantly increased SDLP by 4.0±0.5cm (95% CI: 3.0, 5.1) and SDSP by 0.38±0.10km⋅h -1 (95% CI: 0.19, 0.57). Regression analyses indicate BAC (p=0.004) and driving

    Introduction Historically, the quality and performance of prehospital emergency care (PEC) has been assessed largely based on surrogate, non-clinical endpoints such as response time intervals or other crude measures of care (eg, stakeholder satisfaction). However, advances in Emergency Medical Services (EMS) systems and services world-wide have seen their scope and reach continue to expand. This has dictated that novel measures of performance be implemented to compliment this growth. Significant progress has been made in this area, largely in the form of the development of evidence-informed quality indicators (QIs) of PEC. Problem Quality indicators represent an increasingly popular component of health care quality and performance measurement. However, little is known about the development of QIs in the PEC environment. The purpose of this study was to assess the development and characteristics of PEC-specific QIs in the literature. A scoping review was conducted through a search of PubMed (National Center for Biotechnology Information, National Institutes of Health; Bethesda, Maryland USA); EMBase (Elsevier; Amsterdam, Netherlands); CINAHL (EBSCO Information Services; Ipswich, Massachusetts USA); Web of Science (Thomson Reuters; New York, New York USA); and the Cochrane Library (The Cochrane Collaboration; Oxford, United Kingdom). To increase the sensitivity of the literature, a search of the grey literature and review of select websites was additionally conducted. Articles were selected that proposed at least one PEC QI and whose aim was to discuss, analyze, or promote quality measurement in the PEC environment. The majority of research (n=25 articles) was published within the last decade (68.0%) and largely originated within the USA (68.0%). Delphi and observational methodologies were the most commonly employed for QI development (28.0%). A total of 331 QIs were identified via the article review, with an additional 15 QIs identified via the website review. Of

    Acid-reducing agents (ARAs) are the most commonly prescribed medications in North America and Western Europe. There are currently no data describing the prevalence of their use among cancer patients. However, this is a paramount question due to the potential for significant drug-drug interactions (DDIs) between ARAs, most commonly proton pump inhibitors (PPIs), and orally administered cancer therapeutics that display pH-dependent solubility, which may lead to decreased drug absorption and decreased therapeutic benefit. Of recently approved orally administered cancer therapeutics, >50% are characterized as having pH-dependent solubility, but there are currently no data describing the potential for this ARA-DDI liability among targeted agents currently in clinical development. The objectives of this study were to (1) determine the prevalence of ARA use among different cancer populations and (2) investigate the prevalence of orally administered cancer therapeutics currently in development that may be liable for an ARA-DDI. To address the question of ARA use among cancer patients, a retrospective cross-sectional analysis was performed using two large healthcare databases: Thomson Reuters MarketScan (N = 1,776,443) and the U.S. Department of Veterans Affairs (VA, N = 1,171,833). Among all cancer patients, the total prevalence proportion of ARA use (no. of cancer patients receiving an ARA/total no. of cancer patients) was 20% and 33% for the MarketScan and VA databases, respectively. PPIs were the most commonly prescribed agent, comprising 79% and 65% of all cancer patients receiving a prescription for an ARA (no. of cancer patients receiving a PPI /no. of cancer patients receiving an ARA) for the MarketScan and VA databases, respectively. To estimate the ARA-DDI liability of orally administered molecular targeted cancer therapeutics currently in development, two publicly available databases, (1) Kinase SARfari and (2) canSAR, were examined. For those orally administered

    This paper traces the evolution of measures and parameters for the evaluation of science and scientific journals from the first attempts during the early part of the last century to the development of the most popular, current and widely used metrics viz., citations, impact factor (IF) etc. The identification of measures of evaluation in science and scientific reporting paralled the post-war increase in funding in the United States of America. Biomedical and medical sciences continue to garner a major share, estimated to be almost two-thirds of total research and development funding of over US$ 350 billion. There has been a concomitant growth in the publications in learned journals. About 1.4 million papers are published every year in an estimated 20,000 journals. In India there are an estimated 100 journals in medical sciences. With a steady increase of about 10% every year, the competition for grants, awards, rewards etc., is fierce. This unrelenting increase in number of scientists and the resultant competition, the limitation of peer review was felt. A search was on for new quantifiable measures for informed decision making for funding, awards, rewards, etc. Now virtually all major decisions all over the world are based on some data linked to publications and/or citations. The concept of citations as tool for 'evaluating' science was first proposed by Eugene Garfield in 1955. The availability of Science Citation Index (SCI), Journal Citation Reports (JCR), Web of Science etc. and the relative ease with which they could be used (and abused) has spawned an entirely new area bibliometrics/scientometrics. As only a limited number of journals could be included in the Thomson Reuters (TR) databases (currently numbering about 10500), analyses based on such a limited dataset (also selected in a non-transparent way by the TR) has been widely and severely criticized by both the developed and developing countries. Yet, studies have shown that citation-based data and

    This is the first update of the Cochrane review on mechanical chest compression devices published in 2011 (Brooks 2011). Mechanical chest compression devices have been proposed to improve the effectiveness of cardiopulmonary resuscitation (CPR). To assess the effectiveness of mechanical chest compressions versus standard manual chest compressions with respect to neurologically intact survival in patients who suffer cardiac arrest. We searched the Cochrane Central Register of Controlled Studies (CENTRAL; 2013, Issue 12), MEDLINE Ovid (1946 to 2013 January Week 1), EMBASE (1980 to 2013 January Week 2), Science Citation abstracts (1960 to 18 November 2009), Science Citation Index-Expanded (SCI-EXPANDED) (1970 to 11 January 2013) on Thomson Reuters Web of Science, biotechnology and bioengineering abstracts (1982 to 18 November 2009), conference proceedings Citation Index-Science (CPCI-S) (1990 to 11 January 2013) and clinicaltrials.gov (2 August 2013). We applied no language restrictions. Experts in the field of mechanical chest compression devices and manufacturers were contacted. We included randomised controlled trials (RCTs), cluster RCTs and quasi-randomised studies comparing mechanical chest compressions versus manual chest compressions during CPR for patients with atraumatic cardiac arrest. Two review authors abstracted data independently; disagreement between review authors was resolved by consensus and by a third review author if consensus could not be reached. The methodologies of selected studies were evaluated by a single author for risk of bias. The primary outcome was survival to hospital discharge with good neurological outcome. We planned to use RevMan 5 (Version 5.2. The Nordic Cochrane Centre) and the DerSimonian & Laird method (random-effects model) to provide a pooled estimate for risk ratio (RR) with 95% confidence intervals (95% CIs), if data allowed. Two new studies were included in this update. Six trials in total, including data from 1166

    Dysregulated metabolism is a hallmark of cancer, manifested through alterations in metabolites. We performed metabolomic profiling on 138 matched clear cell renal cell carcinoma (ccRCC)/normal tissue pairs and found that ccRCC is characterized by broad shifts in central carbon metabolism, one-carbon metabolism, and antioxidant response. Tumor progression and metastasis were associated with metabolite increases in glutathione and cysteine/methionine metabolism pathways. We develop an analytic pipeline and visualization tool (metabolograms) to bridge the gap between TCGA transcriptomic profiling and our metabolomic data, which enables us to assemble an integrated pathway-level metabolic atlas and to demonstrate discordance between transcriptome and metabolome. Lastly, expression profiling was performed on a high-glutathione cluster, which corresponds to a poor-survival subgroup in the ccRCC TCGA cohort. Copyright © 2017 Elsevier Inc. All rights reserved.

    Developing data search tools is a very common, but often confusing, task for most of the data intensive scientific projects. These search interfaces need to be continually improved to handle the ever increasing diversity and volume of data collections. There are many aspects which determine the type of search tool a project needs to provide to their user community. These include: number of datasets, amount and consistency of discovery metadata, ancillary information such as availability of quality information and provenance, and availability of similar datasets from other distributed sources. Environmental Data Science and Systems (EDSS) group within the Environmental Science Division at the Oak Ridge National Laboratory has a long history of successfully managing diverse and big observational datasets for various scientific programs via various data centers such as DOE's Atmospheric Radiation Measurement Program (ARM), DOE's Carbon Dioxide Information and Analysis Center (CDIAC), USGS's Core Science Analytics and Synthesis (CSAS) metadata Clearinghouse and NASA's Distributed Active Archive Center (ORNL DAAC). This talk will showcase some of the recent developments for improving the data discovery within these centers The DOE ARM program recently developed a data discovery tool which allows users to search and discover over 4000 observational datasets. These datasets are key to the research efforts related to global climate change. The ARM discovery tool features many new functions such as filtered and faceted search logic, multi-pass data selection, filtering data based on data quality, graphical views of data quality and availability, direct access to data quality reports, and data plots. The ARM Archive also provides discovery metadata to other broader metadata clearinghouses such as ESGF, IASOA, and GOS. In addition to the new interface, ARM is also currently working on providing DOI metadata records to publishers such as Thomson Reuters and Elsevier. The ARM

    Full Text Available Immediately sequential bilateral cataract surgery (ISBCS, the cataract surgery that is performed in both eyes simultaneously, is gaining popularity worldwide compared to the traditional treatment paradigm: delayed sequential bilateral cataract surgery (DSBCS, the surgery that is performed in each eye on a different day as a completely separate operation. ISBCS provides advantages to patients and patients' families in the form of fewer hospital visits. Additionally, patients enjoy rapid rehabilitation, lack of anisometropia - potentially reducing accidents and falls, and avoid suboptimal visual function in daily life. The hospital may benefit due to lower cost.To perform a systematic review and meta-analysis to evaluate ISBCS and DSBCS.Databases including MEDLINE, EMBASE, BIOSIS, CINAHL, Health Economic Evaluations Database (HEED, ISI Web of Science (Thomson-Reuters and the Cochrane Library were searched.Not applicable.Literature was systematically reviewed using EPPI-Reviewer 4 gateway. Meta-analysis was conducted using STATA v. 13.0. Standardized mean difference (SMD and 95% confidence intervals (CI were calculated and heterogeneity was assessed using I2 statistics. Fixed-effect and random-effect models were computed based on heterogeneity. Meta-analysis was done by instrument used to calculate utility score.In total, 9,133 records were retrieved from multiple databases and an additional 128 records were identified through grey literature search. Eleven articles with 3,657 subjects were included for analysis. Our meta-analysis results indicated significant improvement in post-operative utility score using TTO, EQ5D, HUI3, VF-7, and VF-14 and a non-significant improvement using Catquest questionnaire for both surgeries. For ISBCS versus DSBCS, utility-specific fixed-effect model provided an overall SMD of the utility score using the TTO method as 0.12 (95% CI: -0.15, 0.40, EQ5D as 0.14 (95% CI: -0.14, 0.41, HUI3 as 0.12 (95% CI: -0.15, 0.40, VF
