    Full Text Available This paper analyzes seven weeks of Reuters television content from mid-2011. The paper situates academic interest in the global news agencies in the argument for a New World Information and Communication Order (NWICO. It reviews the literature on research of news agency production and identifies the latest modeling of an increasingly sophisticated understanding of the agency-client relationship. The paper describes the ‘big picture’ of the world that Reuters makes available to most clients. It then analyzes that picture in terms of the extant literature and history of Reuters content to determine the degree of change, if any, that is evident in Reuters output today, compared to the past. The paper finds that Reuters continues to focus on the United States and Western Europe. It continues to focus on hard news topics, such as politics, economics, crime and conflict as its core news. It remains a largely Anglophone service and most of its voices of authority are male. Significantly, the paper finds that GDP is a reliable predictor of story count by geographic focus in Reuters output. Cet article analyse sept semaines de contenu Reuters destiné à la télévision, depuis le milieu de l’année 2011.

    Members of the Miridae (Lygus lineolaris Palisot de Beauvois and Pseudatomoscelis seriatus Reuter) and Pentatomidae (Acrosternum hilare Say, Euschistus servus (Say), Euschistus tristigmus (Say), Euschistus quadrator Rolston, Oebalus pugnax (F.), Piezodorus guildinii (Westwood), and Thyanta custator accerra McAtee) comprise a piercing-sucking insect complex that continues to plague multiple crops, including cotton. All these species have been associated with pathogen transmission. Breaching of boll carpel walls facilitates introduction of pathogens, and it is unknown whether stylets of these pests can fully penetrate carpel walls. Thus, stylet penetration estimates are needed and have been the focus of the present work. Stylet penetration estimates for L. lineolaris were significantly deeper than P. seriatus. Among the Pentatomidae, highest mean penetration was estimated for E. servus followed by A. hilare, yet A. hilare possessed a longer rostrum. Similarly, O. pugnax showed deeper penetration estimates than P. guildinii yet P. guildinii possessed a longer rostrum. Thus, rostrum length should not be equated to penetration potential. Pseudatomoscelis seriatus and L. lineolaris both infest early-season cotton, and the ranges of observed penetration indicate these insects, as well as the Pentatomidae, can breach the walls of critical pinhead squares and smaller bolls. The insects addressed herein affect a myriad of crops globally, and penetration estimates allow identification of growth stages susceptible to feeding and disease transmission.

    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.

  10. Risk of damage to tomato crops by the generalist zoophytophagous predator Nesidiocoris tenuis (Reuter) (Hemiptera: Miridae).

    Nesidiocoris tenuis (Reuter) (Hem. Miridae) is a native zoophytophagous predator of the Mediterranean region, and its populations colonize tomato crops when they are not heavily treated with insecticides. This generalist predator has a high capacity for controlling insect pests, and it is currently commercially produced and released in some areas to control Bemisia tabaci (Gennadius) (Hem. Aleyrodidae). However, its status as a pest and/or as beneficial is controversial. Therefore, the aim of this study was to evaluate the risk of damage to tomatoes in extreme conditions of prey scarcity, as well as high predator populations. Three predator densities were tested in a greenhouse cage experiment during a summer tomato crop. The crop did not display any negative effect caused by the predators during the first six weeks of interaction, independently of the density released. However, subsequently, the effect was dramatic, both on the vegetative growth of the plant and on the production of fruits. The reduction in vegetative growth was located at truss eight and it was expressed mainly by a lower number of leaves and a shorter length of the shoot above the truss. There was a significant reduction of yield with a lower number of fruits collected and a smaller mean weight, although this was not observable until truss seven. It seems that feeding on the plant by this mirid bug competed with the vegetative growth and fruiting processes of the plant in the extreme conditions of prey shortage maintained in our experiment.

  11. 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.

    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.

  14. Cotton Square Morphology Offers New Insights into Host Plant Resistance to Cotton Fleahopper (Hemiptera: Miridae) in Upland Cotton.

    Cotton fleahopper, Pseudatomoscelis seriatus (Reuter) (Hemiptera: Miridae), is a piercing-sucking pest of cotton (Gossypium hirsutum L.) that feeds preferentially on developing flower buds, called squares. Heavy infestations cause yield reductions that result from abscission of squares damaged by the cotton fleahopper feeding. Antixenosis, or nonpreference, has been reported as a mechanism of host plant resistance in cotton to cotton fleahopper. Square structure, particularly the placement of the reproductive tissues, and stylet penetration were investigated as factors that influence resistance to cotton fleahopper in cotton lines derived from crosses with Pilose, a cultigen of upland cotton resistant to cotton fleahopper, and backcrossed with high-yielding, susceptible lines. Ovary depth varied among the lines tested and was found to be a heritable trait that affected the ability of a fleahopper's feeding stylets to penetrate the reproductive tissues in the square and might influence preference. Behavioral assays suggested antixenosis as a mechanism of host plant resistance, and the trait conferring antixenosis was found to be heritable. Results suggest ovary depth plays a role in conferring resistance to cotton fleahopper and is an exploitable trait in resistance breeding. © The Authors 2015.

    Cotton fleahopper (Pseudatomoscelis seriatus Reuter) (Hemiptera: Miridae) is a piercing-sucking insect that has emerged as a major pest of cotton (Gossypium hirsutum L.) in Texas. Cotton fleahoppers feed on floral buds, commonly referred to as squares, causing damage and abscission, and subsequent yield loss. Previous studies indicate that plant resistance to cotton fleahopper is present in upland cotton, but the mechanism of resistance remains undetermined. In this study, Pilose, a cultigen of G. hirsutum, was examined as a source of resistance to cotton fleahopper, focusing on mechanism of resistance and heritability of the resistance trait. Results indicated that the resistance trait in Pilose is heritable and that pubescence is causative of resistance or that the resistance trait may be tightly linked to genes controlling pubescence. Behavioral assays indicated nonpreference as a mode of resistance in plants with dense pubescence. © The Authors 2015.

    Cotton fleahopper [Pseudatomoscelis seriatus (Reuter)] (Hemiptera: Miridae) is one of the most damaging insect pests of cotton (Gossypium hirsutum L.) in Texas and Oklahoma because of their feeding on small floral buds which are termed squares. Damage to early season squares can reduce yield, delay crop maturity and increase the risk of crop loss because of late season insect pests and adverse weather. Insecticide applications are the only control tactic. The objectives of this study were to determine the tolerance to cotton fleahopper injury to squares among upland cotton genotypes representing the adapted germplasm pools and breeding lines available to cotton breeders in the United States and to evaluate leaf hairiness as a resistant trait. Results of the choice and no-choice trials indicated that four entries, 'Stoneville 474', 'Suregrow 747', 'Deltapine 50', and 'TAM 96WD-22 h', were more tolerant to cotton fleahopper injury relative to the other 11 entries. In choice trials, cotton fleahopper density was significantly correlated with the density of trichomes on leaves, bracts and stems. However, there was no correlation between cotton fleahopper density and percent square damage in the choice trials, suggesting that in some genotypes the response to feeding injury is mediated by host plant resistance factors expressed as tolerance. Results of the no-choice studies also indicate that some genotypes express tolerance to cotton fleahopper feeding.

    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.

  18. Compatibility assessment between four ethanolic plant extracts with a bug predator Orius horvathi (Reuter (Heteroptera: Anthocoridae used for controlling the western flower thrips Frankliniella occidentalis (Pergande (Thysanoptera: Thripidae

    Full Text Available The western flower thrips, Frankliniella occidentalis (Pergande attacks a large number of crop plants. The current insecticides have caused resistance in insects and have caused outbreaks of thrips. In many instances, alternative methods of insect management and natural products, offer adequate pest control and pose fewer hazards. Several species of minute pirate bugs of the genus Orius play a significant role in the biological control of a large number of thrips species, such as F. occidentalis. In this study, the insecticidal activity of four ethanolic plant extracts (Cercis siliquastrum L., Calendula officinalis L., Peganum harmala L., Melia azedarach L. in integration with Orius horvathi (Reuter were evaluated for controlling F. occidentalis. The present research aimed to find plant extracts with a good impact on F. occidentalis but which have fewer side effects on O. horvathi. The results showed that P. harmala extract can be considered compatible with the natural enemy for controlling thrips. When the predatory bugs O. horvathi, were released three days after P. harmala extract spraying, the integration was more effective. While the P. harmala plant extract plays an important role in thrips control, it is necessary to consider the specified time interval between the application of the P. harmala plant extract and the release of the O. horvathi predatory bugs. The ethanolic extract of M. azedarach caused a balance between the pest population and the natural enemy. This result is very important in an Integrated Pest Management (IPM program because this ethanolic extract of M. azedarach had lower side effects on the natural enemy. This means that an integration of plant derived chemicals and the natural enemy, O. horvathi, can effectively control thrips.

    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

    2004-04-01

    The effects of the red imported fire ant, Solenopsis invicta Buren (Hymenoptera: Formicidae), on cotton aphid, Aphis gossypii Glover, populations and its predation of bollworm, Helicoverpa zea (Boddie), and beet armyworm, Spodoptera exigua (Hübner), (both Lepidoptera: Noctuidae) eggs were evaluated in cotton under field conditions during 2001 and 2002 in central and northern Texas. In central Texas, cotton aphid populations were approximately 5.5 times greater and predation of sentinel bollworm eggs 2 times greater in the presence of S. invicta versus in its absence, although aphid populations did not reach economic levels. Most predation of beet armyworm egg masses, measured via direct nocturnal observations, was due to S. invicta (68%) and cotton fleahopper, Pseudatomoscelis seriatus (Reuter) (21%), where S. invicta was present, and by the mite Abrolophus sp. (52%), spiders (13%), and minute pirate bug (Orius sp.) (13%) where S. invicta was absent. Predation of sentinel bollworm eggs and beet armyworm egg masses was approximately 1.5 and 4.1 times greater, respectively, in the presence of S. invicta versus in their absence. In the presence of S. invicta, the relative frequencies of minute pirate bug and cotton fleahopper were higher, and of S. invicta and native ants lower in beat bucket samples compared with their relative frequencies in nocturnal observations of predation upon beet armyworm egg masses. In the absence of S. invicta seven of eight predators sampled were similarly represented in beat bucket samples and nocturnal observations of beet armyworm egg mass predation, whereas minute pirate bug occurred at a higher frequency in beat bucket samples relative to nocturnal observations. These observations suggested that the relative frequencies of minute pirate bug, cotton fleahopper, S. invicta and native ants in beat bucket samples do not closely reflect the frequency with which these predators prey on noctuid eggs. Overall, the results of this study show

    2017-05-01

    Full Text Available The objective of this paper is to analyse Thomas Reuter’s seminal text The Custodians of the Sacred Mountains and to discuss some of the theoretical and other issues that flow from the reading. Indirectly it is also intended to assist many local scholars who find the text somewhat impenetrable, let alone making connections to its extensive implications. The book is the second study to emerge that covers the regional basis for the Bali Aga, the first being that of Wälty (1997. The text is one of a kind - erudite, complex and intellectually challenging. The paper begins with historical interventions since the status economy of Bali Aga is wholly dependent on a mythical past. Next, the use of theory, focussing on anthropology and Bali studies is discussed to place Reuter’s work in context. Then his basic concepts are analysed, those of precedence, status, and representation. Subsequently, we focus on place and space since geography is a defining feature of Bali Aga. Finally the mental (symbolic and material (political economy dimensions are contrasted with the observation that omission of any consideration of the latter weakens an otherwise seminal work.

    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.

    Full Text Available A description of how a conspicuous anomaly in the Web of Science (WoS database was detected. Beginning in 2002 the WoS randomly mistook and interspersed numerous articles from two different journals, one American and the other South Korean, both specialized in public relations and sharing the same title: Journal of Public Relations Research. The case is especially noteworthy since these are two publications written in very different languages (English and Korean, with different ISSN numbers and editorial outlooks, and whose respective volumes share neither authors nor content.Descripción del proceso mediante el cual se habría detectado una notable anomalía en la base de datos bibliográficos de la Web of Science (WoS. Concretamente, desde el año 2002 la WoS habría confundido y entremezclado aleatoriamente numerosos artículos de dos revistas distintas, ambas especializadas en relaciones públicas, una norteamericana y otra surcoreana, que comparten un mismo título: Journal of Public Relations Research. El caso es especialmente relevante al tratarse de dos publicaciones escritas en idiomas totalmente distintos (inglés y coreano, con diferentes números de ISSN y con distintas líneas editoriales, en cuyos respectivos volúmenes no coinciden ni autores, ni contenido.

    2015-01-01

    ​Using the domain of crisis management, Christian Reuter explores challenges and opportunities for technology design in emergent environments. He therefore empirically analyzes collaborative work in inter-organizational crisis - such as the police, fire departments, energy network operators and citizens - in order to identify collaboration practices that reveal work infrastructure limitations. He also designs, implements and evaluates novel concepts and ICT artifacts towards the support of emergent collaboration. Besides the discovery of potential organizational effects on the ability to deal

We propose a generic and robust approach for high-recall named entity recognition.

Our approach is based on deep contextual sequence learning and utilizes stacked bidir...

    Full Text Available Data on natural enemies of psyllids are rare and can usually be found in papers about economically significant species. During an investigation of psyllid fauna in Serbia, natural enemies were investigated, too. True bugs were the most numerous among them. From 28 psyllid species, 21 species of true bugs from families Anthocoridae and Miridae were reared. Seven species of Anthocoridae were identified: Anthocoris amplicollis (Horváth, 1839, A. confusus Reuter, 1884, A. nemoralis (Fabricius, 1794, A. nemorum (Linnaeus, 1761, Orius majusculus Reuter, 1884, O. minutus (Linnaeus, 1758 and O. niger Wolff, 1811. The following 14 species of Miridae were identified: Atractotomus mali Meyer-Dür, 1843, Campylomma verbasci (Meyer-Dür, 1843, Deraeocoris flavilinea (A.

The aim of the research was to provide list of true bugs recorded as predators of psyllids in order to preserve their diversity and significance, especially on cultivated plants.

    Toward development of a precision medicine framework for metastatic, castration-resistant prostate cancer (mCRPC), we established a multi-institutional clinical sequencing infrastructure to conduct prospective whole-exome and transcriptome sequencing of bone or soft tissue tumor biopsies from a cohort of 150 mCRPC affected individuals. Aberrations of AR, ETS genes, TP53, and PTEN were frequent (40%-60% of cases), with TP53 and AR alterations enriched in mCRPC compared to primary prostate cancer. We identified new genomic alterations in PIK3CA/B, R-spondin, BRAF/RAF1, APC, β-catenin, and ZBTB16/PLZF. Moreover, aberrations of BRCA2, BRCA1, and ATM were observed at substantially higher frequencies (19.3% overall) compared to those in primary prostate cancers. A total of 89% of affected individuals harbored a clinically actionable aberration, including 62.7% with aberrations in AR, 65% in other cancer-related genes, and 8% with actionable pathogenic germline alterations. This cohort study provides clinically actionable information that could affect treatment decisions for these affected individuals. Copyright © 2017 Elsevier Inc. All rights reserved.

The experimental results showed that our method can effectively classify texts with the best F1-measure of 92.5%. It also showed the learning algorithm can enhance the accuracy effectively and efficiently. This framework also validates scalability in terms of the network size, in which the training and testing times both showed a constant trend. This also validates the feasibility of the method for practical uses.

    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

    Beginning about three years ago, the world of academic publishing has become infected by fake impact factors and misleading metrics that are launched by bogus companies. The misleading metrics and fake impact factors have damaged the prestige and reliability of scientific research and scholarly journals. This article presents the in-depth story of some of the main bogus impact factors, how they approached the academic world, and how the author identified them. Some names that they use are Universal Impact Factor (UIF), Global Impact Factor (GIF), and Citefactor, and there even is a fake Thomson Reuters Company.

    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.

    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.

    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.

    Though postgraduate education started before the founding of new China in 1949, it was not until the implementation of the policy reform and the opening-up in 1978 that China's postgraduate productivity began to take off. Since the introduction of Regulations of the People's Republic of China on Academic Degrees in 1981, the number of graduate students enrolled each year has increased 50 times since 1978. China is now the second largest producer of publications indexed by the database of Science Citation Index (SCI) (Web of Science™, Thomson Reuters), which reflects great strides being made in the postgraduate education. In this paper, we discuss the relationship between the increasingly high enrollments of graduate students and the quantity (the number) and quality (the academic impact and the originality) of their publications, to see whether there is a correlation.

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

    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].

We have applied the forecast system to a network of road weather stations (road weather information system, RWIS) installed on the test route [4].

  14. Poisonings and clinical toxicology: a template for Ireland.

    LENUS (Irish Health Repository)

    Tormey, W P

    2013-03-01

    Poisons information is accessed around the clock in the British Isles from six centres of which two are in Ireland at Dublin and Belfast accompanied by consultant toxicologist advisory service. The numbers of calls in Ireland are down to about 40 per day due to easy access to online data bases. Access to Toxbase, the clinical toxicology database of the National Poisons Information Service is available to National Health Service (NHS) health professionals and to Emergency Departments and Intensive Care units in the Republic of Ireland. There are 59 Toxbase users in the Republic of Ireland and 99 % of activity originates in Emergency Departments. All United States Poison Control Centres primarily use Poisindex which is a commercial database from Thomson Reuters.

    2006-05-01

    We address the general problem of how to quantify the kinematics of time series with stationary first moments but having non stationary multifractal long-range correlated second moments. We show that a Markov process is sufficient to model important aspects of the multifractality observed in financial time series and propose a kinematic model of price fluctuations. We test the proposed model by analyzing index closing prices of the New York Stock Exchange and the DEM/USD tick-by-tick exchange rates obtained from Reuters EFX. We show that the model captures the characteristic features observed in actual financial time series, including volatility clustering, time scaling and fat tails in the probability density functions, power-law behavior of volatility correlations and, most importantly, the observed nonuniversal multifractal singularity spectrum. Motivated by our finding of strong agreement between the model and the data, we argue that at least two independent stochastic Gaussian variables are required to adequately model price fluctuations.

    2010-01-01

    Full Text Available The objetive of this study is to offer a clear and practical overview to the Chemical Scientist, applying quantitative methods on the two most extended platforms of scientific information nowadays: Web of Science (Thomson Reuters and Scopus (Elsevier. It was carried out a specialized search in the area of the chemical engineering in both databases between 1999 and 2006. Through the articles recovered in the searches during those ten years and the journals recovered in 2006, it is analyzed the possible correlation between both systems; the pattern of growth that they show and certain parameters of that growth; the overlapping among the two databases, the dispersion of the articles in the journals and concentration measures, between others. The results show the existence of a high likeness between Web of Science and Scopus, turning out complementary but not exclusive, regarding their possible use for the chemical engineers.

    2016-07-01

    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)

  18. A Matter of Trust

  19. Deep Learning of Constrained Autoencoders for Enhanced Understanding of Data.

    Science.gov (United States)

    Ayinde, Babajide O; Zurada, Jacek M

    2017-09-26

    Unsupervised feature extractors are known to perform an efficient and discriminative representation of data. Insight into the mappings they perform and human ability to understand them, however, remain very limited. This is especially prominent when multilayer deep learning architectures are used. This paper demonstrates how to remove these bottlenecks within the architecture of non-negativity constrained autoencoder. It is shown that using both L1 and L2 regularizations that induce non-negativity of weights, most of the weights in the network become constrained to be non-negative, thereby resulting into a more understandable structure with minute deterioration in classification accuracy. Also, this proposed approach extracts features that are more sparse and produces additional output layer sparsification. The method is analyzed for accuracy and feature interpretation on the MNIST data, the NORB normalized uniform object data, and the Reuters text categorization data set.

    This study compares the performances of new-molecule (NM) launches in Turkey with those in the European Union and United States for the years 2007-2013. The Thomson Reuters Newport Horizon for Innovators Database is used to identify NMs with a launch date after January 1, 2007, worldwide and marketing authorization approval after January 1, 2007, in the European Union. The launch dates for the European Union, the United States, and Turkey were retrieved from the same database. Data for Turkey were confirmed via IMS and RxMedia. Out of 183 records identified that are launched in the European Union, the United States, or both, 44 of the NMs are launched in Turkey (24%). The results of this study show that 24% of the NMs that are launched in either the European Union or United States were able to be launched in Turkey with a mean delay of 821 days (2.25 years).

    2012-01-01

    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.) affect trading and the pricing of firms in organized stock markets. In this paper 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 205 major stocks in the S&P US stock index. We show that the whole landscape of news that affect 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 in...

    Identifying metaphorical language-use (e.g., sweet child) is one of the challenges facing natural language processing. This paper describes three novel algorithms for automatic metaphor identification. The algorithms are variations of the same core algorithm. We evaluate the algorithms on two corpora of Reuters and the New York Times articles. The paper presents the most comprehensive study of metaphor identification in terms of scope of metaphorical phrases and annotated corpora size. Algorithms' performance in identifying linguistic phrases as metaphorical or literal has been compared to human judgment. Overall, the algorithms outperform the state-of-the-art algorithm with 71% precision and 27% averaged improvement in prediction over the base-rate of metaphors in the corpus.

    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.

  7. Spatial working memory maintenance: does attention play a role? A visual search study.

    Science.gov (United States)

    Chan, Louis K H; Hayward, William G; Theeuwes, Jan

    2009-10-01

    Recent studies have proposed that a common mechanism may underlie spatial attention and spatial working memory. One proposal is that spatial working memory is maintained by attention-based rehearsal [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], and so a spatial attention shift during the retention interval of a spatial location should impair its memory performance. In the present study, participants engaged in single-item, parallel or serial search tasks while remembering a spatial location. Although memory tended to bias all searches, the need for an attentional shift during the retention interval impaired memory performance only in single-item search, but not in other searches. These findings suggest that previous evidence for the attention-based rehearsal account does not generalize to visual search. Results are discussed with regard to the relationship between spatial attention and spatial working memory.

    Bhattacharya, Anasua; Leigh, J Paul

    2011-01-01

    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).

    This conference proceeding presents an empirical assessment on the domestic publication output and structure of scientific collaboration of Malaysian authors for the field of physics. Journal articles with Malaysian addresses for the subject area "Physics" and other sub-discipline of physics were retrieved from the Thomson Reuters Web of Knowledge database spanning the years 1980 to 2011. A scientometrics and social network analysis of the Malaysian physics field was conducted to examine the publication growth and distribution of domestic collaborative publications; the giant component analysis; and the degree, closeness, and betweenness centralisation scores for the domestic co-authorship networks. Using these methods, we are able to gain insights on the evolution of collaboration and scientometric dimensions of Malaysian research in physics over time.

    In August 2011, Thomson Reuters launched version 5 of the Science and Social Science Citation Index in the Web of Science (WoS). Among other things, the 222 ISI Subject Categories (SCs) for these two databases in version 4 of WoS were renamed and extended to 225 WoS Categories (WCs). A new set of 74 Subject Categories (SCs) was added, but at a higher level of aggregation. Since we previously used the ISI SCs as the baseline for a global map in Pajek (Rafols et al., 2010) and brought this facility online (at http://www.leydesdorff.net/overlaytoolkit), we recalibrated this map for the new WC categories using the Journal Citation Reports 2010. In the new installation, the base maps can also be made using VOSviewer (Van Eck & Waltman, 2010).

  15. Cardiac strength-interval curves calculated using a bidomain tissue with a parsimonious ionic current.

    Directory of Open Access Journals (Sweden)

    Suran K Galappaththige

    Full Text Available The strength-interval curve plays a major role in understanding how cardiac tissue responds to an electrical stimulus. This complex behavior has been studied previously using the bidomain formulation incorporating the Beeler-Reuter and Luo-Rudy dynamic ionic current models. The complexity of these models renders the interpretation and extrapolation of simulation results problematic. Here we utilize a recently developed parsimonious ionic current model with only two currents-a sodium current that activates rapidly upon depolarization INa and a time-independent inwardly rectifying repolarization current IK-which reproduces many experimentally measured action potential waveforms. Bidomain tissue simulations with this ionic current model reproduce the distinctive dip in the anodal (but not cathodal strength-interval curve. Studying model variants elucidates the necessary and sufficient physiological conditions to predict the polarity dependent dip: a voltage and time dependent INa, a nonlinear rectifying repolarization current, and bidomain tissue with unequal anisotropy ratios.

    The so called 'incomplete hole shell filling' phenomenon, that is the breaking of the Aufbau principle was reported by Reuter et al (Phys. Rev. Lett. 94 026808) in the hole charging spectra of a quantum dot when the results were interpreted in the context of the s/p/d shell system-typical for electrons. We report an example of an inter-particle-interaction induced Aufbau principle violation even if it is applied to the one-particle Kohn-Luttinger eigenstates. We present a [Formula: see text]/configuration-interaction study that concerns multiple holes confined in an InGaAs/GaAs self-assembled cylindrical quantum dot. The eigenenergies and eigenvectors of up to six hole ground states were obtained-along with the corresponding one-hole orbital occupations-and discussed in the context of the Aufbau principle.

    This study analyses the research on disdrometers based on published studies. To do so, a wide data base of bibliographic references has been used: the Web of Science (published by Thomson Reuters). The search was carried out for all of the articles whose "TOPIC" was disdrometer. The more than 300 articles found were analysed according to various criteria: countries with research using disdrometers; publication dates; evolution of the number of articles; concepts studied and research lines followed in each article; and finally, a bibliometric analysis of the more than 60 journals where these articles have been published. Since 1963, there has been an increase in the number of articles published on disdrometers, which in the last 20 yr has been more than ten times higher than the increase in the number of articles on meteorology.

    Over the last decade, the presence of microplastics on marine environments has become an important environmental concern and focus of interest of many researches. Thus, to provide a more integrated view of the research trends regarding this topic, we use a scientometric approach to systematically assess and quantify advances in knowledge related to microplastics in the marine environment. The papers that we used for our assessment were obtained from the database Thomson Reuters (ISI Web of Science), between 2004 and 2014. Our results reveal the overall research performance in the study area of microplastics present in the marine environment over the past decade as a newly developed research field. It has been recognized that there are several important issues that should be investigated. Toward that end, based on the suggested directions on all papers reviewed, we point out areas/topics of interest that may guide future work in the coming years. Copyright © 2015 Elsevier Ltd.

    Two oriine flower bug (Hemiptera: Heteroptera: Anthocoridae) genera, Bilia Distant, 1904 and Wollastoniella Reuter, 1884 are reported from Myanmar for the first time, diagnosed, and discussed. A new species, Bilia burma Yasunaga & Yamada sp. nov., is described, with information on the immature form, habitat and assumed prey; its closest sister species, B. castanea (Carvalho, 1951), is also re-diagnosed. Wollastoniella rotunda Yasunaga & Miyamoto, 1993 originally described from northern Thailand, is also documented along with its immature form and new host association. Both of the anthocorids found in Myanmar co-occurred with lace bugs (Tingidae). A checklist of all current members of Bilia and Wollastoniella is provided. The phylogenic positions of Bilia and Wollastoniella in the tribe Oriini is discussed.

    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.

    Full Text Available In the very beginning of this particular paper, an author is trying to determine and describe who Millennials actually are. Then, the basis of Millennials definition is analysing corporation’s activity over the past years regarding this age group. The main goal of the thesis is to bring their specific futures out and describe what corporations on Polish job market are doing to encourage them to work in their offices. Especially in Poland within the last years, it is observed that big multinational companies are paying special attention to Millennials and trying to hire them before competitors will do so. As a part of this paper, an author will describe corporate politics and practices on Thomson Reuters and BNY Mellon examples. Within this work, an author is also discussing key features and differences between this generation and Millennials parent’s generation. Additionally, there is a reference to corporate social responsibility concept and work-life balance issues.

    A pilot study by 6 Clinical and Translational Science Awards (CTSAs) explored how bibliometrics can be used to assess research influence. Evaluators from 6 institutions shared data on publications (4202 total) they supported, and conducted a combined analysis with state-of-the-art tools. This paper presents selected results based on the tools from 2 widely used vendors for bibliometrics: Thomson Reuters and Elsevier. Both vendors located a high percentage of publications within their proprietary databases (>90%) and provided similar but not equivalent bibliometrics for estimating productivity (number of publications) and influence (citation rates, percentage of papers in the top 10% of citations, observed citations relative to expected citations). A recently available bibliometric from the National Institutes of Health Office of Portfolio Analysis, examined after the initial analysis, showed tremendous potential for use in the CTSA context. Despite challenges in making cross-CTSA comparisons, bibliometrics can enhance our understanding of the value of CTSA-supported clinical and translational research.

  11. Models of defibrillation of cardiac tissue

    1998-03-01

    Heterogeneities, such as gap junctions, defects in periodical cellular lattices, intercellular clefts and fiber curvature allow one to understand the effect of an electric field in cardiac tissue. They induce membrane potential variations even in the bulk of the myocardium, with a characteristic sawtooth shape. The sawtooth potential, induced by heterogeneities at large scales (tissue strands) can be more easily observed, and lead to stronger effects than the one induced at the cellular level. In the generic model of propagation in cardiac tissue (FitzHugh), 4 mechanisms of defibrillation were found, two mechanisms based on excitation (EA,EM), and two—on de-excitation (DA,DM). The lowest electric field is required by an EM mechanism. In the Beeler-Reuter ionic model, mechanism DM is impossible. We critically review the experimental basis of the theory and propose new experiments.

  12. Magnitude 8.1 Earthquake off the Solomon Islands

    2007-01-01

    On April 1, 2007, a magnitude 8.1 earthquake rattled the Solomon Islands, 2,145 kilometers (1,330 miles) northeast of Brisbane, Australia. Centered less than ten kilometers beneath the Earth's surface, the earthquake displaced enough water in the ocean above to trigger a small tsunami. Though officials were still assessing damage to remote island communities on April 3, Reuters reported that the earthquake and the tsunami killed an estimated 22 people and left as many as 5,409 homeless. The most serious damage occurred on the island of Gizo, northwest of the earthquake epicenter, where the tsunami damaged the hospital, schools, and hundreds of houses, said Reuters. This image, captured by the Landsat-7 satellite, shows the location of the earthquake epicenter in relation to the nearest islands in the Solomon Island group. Gizo is beyond the left edge of the image, but its triangular fringing coral reefs are shown in the upper left corner. Though dense rain forest hides volcanic features from view, the very shape of the islands testifies to the geologic activity of the region. The circular Kolombangara Island is the tip of a dormant volcano, and other circular volcanic peaks are visible in the image. The image also shows that the Solomon Islands run on a northwest-southeast axis parallel to the edge of the Pacific plate, the section of the Earth's crust that carries the Pacific Ocean and its islands. The earthquake occurred along the plate boundary, where the Australia/Woodlark/Solomon Sea plates slide beneath the denser Pacific plate. Friction between the sinking (subducting) plates and the overriding Pacific plate led to the large earthquake on April 1, said the United States Geological Survey (USGS) summary of the earthquake. Large earthquakes are common in the region, though the section of the plate that produced the April 1 earthquake had not caused any quakes of magnitude 7 or larger since the early 20th century, said the USGS.

    Full Text Available O presente artigo compara duas versões audiovisuais de A Fantástica Fabrica de Chocolate – a do diretor Mel Stuart (1971 e a do diretor Tim Burton (2005, ambas adaptadas da obra literária de mesmo nome, do escritor Roald Dahl (1964. 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.

    Reporting randomised controlled trials is a key element in order to disseminate research findings. The CONSORT statement was introduced to improve the reporting quality. We assessed the adherence to the CONSORT statement of randomised controlled trials published 2011 in the top ten ranked journals of critical care medicine (ISI Web of Knowledge 2011, Thomson Reuters, London UK). Design. We performed a retrospective cross sectional data analysis. Setting. This study was executed at the University Hospital of RWTH, Aachen. Participants. We selected the following top ten listed journals according to ISI Web of Knowledge (Thomson Reuters, London, UK) critical care medicine ranking in the year 2011: American Journal of Respiratory and Critical Care Medicine, Critical Care Medicine, Intensive Care Medicine, CHEST, Critical Care, Journal of Neurotrauma, Resuscitation, Pediatric Critical Care Medicine, Shock and Minerva Anestesiologica. Main outcome measures. We screened the online table of contents of each included journal, to identify the randomised controlled trials. The adherence to the items of the CONSORT Checklist in each trial was evaluated. Additionally we correlated the citation frequency of the articles and the impact factor of the respective journal with the amount of reported items per trial. We analysed 119 randomised controlled trials and found, 15 years after the implementation of the CONSORT statement, that a median of 61,1% of the checklist-items were reported. Only 55.5% of the articles were identified as randomised trials in their titles. The citation frequency of the trials correlated significantly (rs = 0,433; p<0,001 and r = 0,331; p<0,001) to the CONSORT statement adherence. The impact factor showed also a significant correlation to the CONSORT adherence (r = 0,386; p<0,001). The reporting quality of randomised controlled trials in the field of critical care medicine remains poor and needs considerable improvement.

    After long drawn out investigations and tests, the Berlin Senate took a decision at the beginning of 1991, to have the part of the approximately 170 km long interconnection between the West European UCPTE network and the existing 380 kV network of BEWAG lying in the Berlin city area made as an underground cable system. During a construction period of about three years, from Autumn 1991 onwards, an approx. 7.6 km long double cable system, between a newly erected switching station SA Teufelsbruch at the north-western edge of the city and the existing 380/110 kV transformer substation UW Reuter, was erected and set to work in December 1994. The authors describe the concepts and their realisation in the construction of the cable route, in the laying of cooling pipes and in the laying and mounting of cables. (orig.)

    2012-10-01

    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.

    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.

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.

    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

    Full Text Available Soil pH is one of the most important chemical parameters of soil, playing an essential role on the agricultural production and on the distribution of plants and soil biota communities. It is the expression of soil genesis that in turns is a function of soil forming factors and influences all the chemical, physical and biological processes that occur in the soil. Thus it shapes the entire soil ecosystem. Due to any of the above reasons, mapping of soil pH becomes very important to provide harmonised soil pH data to policy makers, public bodies and researchers. In order to obtain a continuous mapping of soil pH for Europe, adopting the digital soil mapping approach, a set of continuously distribute covariates, highly correlated with pH, were selected. The estimate of soil pH was realized using a regression procedure, coupled with the kriging of the residuals. More than 30.000 points on top soil pH (CaCl2 were used, and 27 covariates were tested as predictors. The similar approach was already applied with 12.333 samples to produce a pH map of Europe using European Soil Profile Data in 2008 which compiles several databases from 11 different sources (Reuter et al. 2008. Our study was conducted to update the previous data and maps based on LUCAS (EUROSTAT - Land Use/Cover Area frame statistical Survey, BIOSOIL (Hiederer and Durrant, 2010 and merged database which was used to produce previous soil pH map of Europe (Reuter et al. 2008. We used a compilation of more than 30.000 soil pH measurements from 13 different sources to create a continuous map of soil pH across Europe using a geostatistical approach based on regression-kriging. Regression was based on the use of 27 covariates in the form of raster maps at 1km resolution to explain the differences in the distribution of soil pH in CaCl2 and we added the kriged map of the residuals from the regression model.

    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{sub K1} channels is low enough. At too high an expression level of I{sub K1} channels, oscillations cannot be induced, no matter how many pacemaker channels are expressed. (2) At low expression levels of I{sub K1} 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{sub K1} 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 {approx}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{sub K1} 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.

    Age related macular degeneration (AMD) is a progressive eye disease that, as of 2015, has affected 11 million people in the U.S. and 1.5 million in Canada causing central vision blindness. By 2050, this number is expected to double to 22 million. Eccentric vision is the target of low-vision rehabilitation aids and programs for patients with AMD, which are thought to improve functional performance by improving reading speed and depression. This study evaluates the effect of various low-vision rehabilitation strategies on reading speed and depression in patients 55 and older with AMD. Computer databases including MEDLINE (OVID), EMBASE (OVID), BIOSIS Previews (Thomson-Reuters), CINAHL (EBSCO), Health Economic Evaluations Database (HEED), ISI Web of Science (Thomson-Reuters) and the Cochrane Library (Wiley) were searched from the year 2000 to January 2015. Included papers were research studies with a sample size of 20 eyes or greater focused on AMD in adults aged 55 or older with low vision (20/60 or lower). Two independent reviewers screened and extracted relevant data from the included articles. Standardized mean difference (SMD) was chosen as an effect size to perform meta-analysis using STATA. Fixed- and random-effect models were developed based on heterogeneity. Reading Speed and Depression Scores. A total of 9 studies (885 subjects) were included. Overall, a significant improvement in reading speed was found with a SMD of 1.01 [95% CI: 0.05 to 1.97].

    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.

  11. Vortex dynamics in three-dimensional continuous myocardium with fiber rotation: Filament instability and fibrillation

    Fenton, Flavio; Karma, Alain

    1998-03-01

    Wave propagation in ventricular muscle is rendered highly anisotropic by the intramural rotation of the fiber. This rotational anisotropy is especially important because it can produce a twist of electrical vortices, which measures the rate of rotation (in degree/mm) of activation wavefronts in successive planes perpendicular to a line of phase singularity, or filament. This twist can then significantly alter the dynamics of the filament. This paper explores this dynamics via numerical simulation. After a review of the literature, we present modeling tools that include: (i) a simplified ionic model with three membrane currents that approximates well the restitution properties and spiral wave behavior of more complex ionic models of cardiac action potential (Beeler-Reuter and others), and (ii) a semi-implicit algorithm for the fast solution of monodomain cable equations with rotational anisotropy. We then discuss selected results of a simulation study of vortex dynamics in a parallelepipedal slab of ventricular muscle of varying wall thickness (S) and fiber rotation rate (θz). The main finding is that rotational anisotropy generates a sufficiently large twist to destabilize a single transmural filament and cause a transition to a wave turbulent state characterized by a high density of chaotically moving filaments. This instability is manifested by the propagation of localized disturbances along the filament and has no previously known analog in isotropic excitable media. These disturbances correspond to highly twisted and distorted regions of filament, or "twistons," that create vortex rings when colliding with the natural boundaries of the ventricle. Moreover, when sufficiently twisted, these rings expand and create additional filaments by further colliding with boundaries. This instability mechanism is distinct from the commonly invoked patchy failure or wave breakup that is not observed here during the initial instability. For modified Beeler-Reuter

    2010-06-01

    Creation and clearance of pharmaceutical trademarks continues to be one of the most difficult and challenging areas of trademark law. The Food and Drug Administration (FDA) recently initiated a 2-year Pilot Program under Prescription Drug User Fee Act (PDUFA) IV. The intent of the program is to enable participating pharmaceutical firms to evaluate proposed pharmaceutical marks and submit the data generated from those evaluations to the FDA for review. Submitting a trademark to the FDA warrants questions: What supporting data is needed and accepted when proposing a mark? What issues might arise, and how can they be averted? In a recent Thomson Reuters on-demand webinar (http://science.thomsonreuters.com/news/2010-02/8580404/), a group of renowned experts in the field of trademark development review the FDA pilot program, outline the requirements for submission and discuss what the changes will mean in clearing new pharmaceutical marks. They also present various approaches to trademark development and evaluation in light of the FDA's views. Copyright (c) 2010 Prous Science, S.A.U. or its licensors. All rights reserved.

    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.

    Many studies in information science have looked at the growth of science. In this study, we re-examine the question of the growth of science. To do this we (i) use current data up to publication year 2012 and (ii) analyse it across all disciplines and also separately for the natural sciences and for the medical and health sciences. Furthermore, the data are analysed with an advanced statistical technique (segmented regression analysis) which can identify specific segments with similar growth rates in the history of science. The study is based on two different sets of bibliometric data: (1) The number of publications held as source items in the Web of Science (WoS, Thomson Reuters) per publication year and (2) the number of cited references in the publications of the source items per cited reference year. We have looked at the rate at which science has grown since the mid-1600s.

Bibliometric analysis. Publications in the English language that included citations to Wikipedia were retrieved using the online databases Scopus and Web of Science. To identify health science journals, results were refined using Ulrich's database, selecting for citations from journals indexed in Medline, PubMed, or Embase. Using Thomson Reuters Journal Citation Reports, 2011 impact factors were collected for all journals included in the search. Resulting citations were thematically coded, and descriptive statistics were calculated. 1433 full text articles from 1008 journals indexed in Medline, PubMed, or Embase with 2049 Wikipedia citations were accessed. The frequency of Wikipedia citations has increased over time; most citations occurred after December 2010. More than half of the citations were coded as definitions (n = 648; 31.6%) or descriptions (n=482; 23.5%). Citations were not limited to journals with a low or no impact factor; the search found Wikipedia citations in many journals with high impact factors. Many publications are citing information from a tertiary source that can be edited by anyone, although permanent, evidence based sources are available. We encourage journal editors and reviewers to use caution when publishing articles that cite Wikipedia.

    A new detection system based on an array of 3He tubes and innovative fast detection electronics was designed and produced by GE Reuter Stokes for the high-intensity small-angle neutron scattering diffractometer KWS-2, operated by the Jülich Centre for Neutron Science (JCNS) at the Heinz Meier-Leibnitz Zentrum (MLZ). The new detector consists of a panel array of 144 3He tubes and a new fast read-out electronics. The electronics is mounted in a closed case in the backside of the 3He tubes panel array and will operate at ambient atmosphere under cooling air stream. The new detection system is composed of eighteen 8-pack modules of 3He-tubes that work independently of one another (each unit has its own processor and electronics). Knowing beforehand the performance of one detector unit and of one single tube detector is prerequisite for tuning and maximizing the performance of the complete detection system. In this paper we present the results of the tests of the prototyped 8-pack of 3He-tubes and corresponding electronics, which have been carried out at the JCNS instruments KWS-2 (in high flux conditions) and TREFF.

  20. Measuring Time-Dynamics and Time-Stability of Journal Rankings in Mathematics and Physics by Means of Fractional p-Variations

    Directory of Open Access Journals (Sweden)

    Antonia Ferrer-Sapena

    2017-09-01

    Full Text Available Journal rankings of specific research fields are often used for evaluation purposes, both of authors and institutions. These rankings can be defined by means of several methods, as expert assessment, scholarly-based agreements, or by the ordering induced by a numeric index associated to the prestige of the journals. In order to be efficient and accepted by the research community, it must preserve the ordering over time, at least up to a point. Otherwise, the procedure for defining the ranking must be revised to assure that it reflects the presumably stable characteristic “prestige” that it claims to be quantifying. A mathematical model based on fractional p-variations of the values of the order number of each journal in a time series of journal rankings is explained, and its main properties are shown. As an example, we study the evolution of two given ordered lists of journals through an eleven-year series. These journal ranks are defined by using the 2-year Impact Factor of Thomson-Reuters (nowadays Clarivate Analytics lists for MATHEMATICS and PHYSICS, APPLIED from 2002 to 2013. As an application of our model, we define an index that precludes the use of journal ranks for evaluation purposes when some minimal requirements on the associated fractional p-variations are not satisfied. The final conclusion is that the list of mathematics does not satisfy the requirements on the p-variations, while the list of applied physics does.

  1. Reverberation index: a novel metric by which to quantify the impact of a scientific entity on a given field.

    Kathleen Bandt, S; Dacey, Ralph G

    2017-09-01

    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.

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..

    As global climate change is becoming an increasingly important political and social issue, it is essential for the cryospheric and global change research communities to speak with a single voice when using basic terminology to communicate research results and describe underlying physical processes. Experienced science communicators have highlighted the importance of using the correct terms to communicate research results to the media and general public [e.g., Akasofu, 2008; Hassol, 2008]. The consequences of scientists using improper terminology are at best oversimplification, but they more likely involve misunderstandings of the facts by the public. A glaring example of scientifically incorrect terminology appearing frequently in scientific and public communication relates to reports on the degradation of permafrost. Numerous research papers have appeared in recent years, broadly echoed in the news media, describing the “melting of permafrost,” its effects in the Arctic, and its feedbacks on climate through the carbon cycle. Although permafrost researchers have attempted to distinguish between the appropriate term “permafrost thawing” and the erroneous “permafrost melting” [e.g., van Everdingen, 2005; French, 2002], the latter is still used widely. A Web-based search using the phrase “permafrost melting” reveals hundreds of occurrences, many from highly regarded news and scientific organizations, including Reuters, New Scientist, ABC, The Guardian, Discovery News, Smithsonian magazine, the National Science Foundation, and others.

    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.

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

    Directory of Open Access Journals (Sweden)

    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.

  6. Mapping the Emergence of Synthetic Biology.

    Directory of Open Access Journals (Sweden)

    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.

    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 Scientists and Engineers per million inhabitants and Human Development Index. Average 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.

    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.

    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 concept of mentalizing has captured the interest and imagination of an astonishing range of people-from psychoanalysts to neuroscientists, from child development researchers to geneticists, from existential philosophers to phenomenologists-all of whom seem to have found it useful. According to the Thompson Reuter maintained Web of Science, the use of the term in titles and abstracts of scientific papers increased from 10 to 2,750 between 1991 and 2011. Clinicians in particular have enthusiastically embraced the idea, and have put it to innovative use in their practices. Mentalization-based treatment (MBT)-making mentalizing a core focus of therapy-was initially developed for the treatment of borderline personality disorder (BPD) in routine clinical services delivered in group and individual modalities. Therapy with mentalizing as a central component is currently being developed for treatment of numerous groups, including people with antisocial personality disorder, substance abuse, eating disorders, and at-risk mothers with infants and children (A. Bateman & Fonagy, 2011). It is also being used with families and adolescents, in schools, and in managing social groups (Asen & Fonagy, 2011; Fonagy et al., 2009; Twemlow, Fonagy, & Sacco, 2005a, 2005b). In this article, we focus on MBT in the treatment of BPD.

  12. Barcoding Fauna Bavarica: 78% of the Neuropterida fauna barcoded!

    Full Text Available This publication provides the first comprehensive DNA barcode data set for the Neuropterida of Central Europe, including 80 of the 102 species (78% recorded from Bavaria (Germany and three other species from nearby regions (Austria, France and the UK. Although the 286 specimens analyzed had a heterogeneous conservation history (60% dried; 30% in 80% EtOH; 10% fresh specimens in 95% EtOH, 237 (83% generated a DNA barcode. Eleven species (13% shared a BIN, but three of these taxa could be discriminated through barcodes. Four pairs of closely allied species shared barcodes including Chrysoperla pallida Henry et al., 2002 and C. lucasina Lacroix, 1912; Wesmaelius concinnus (Stephens, 1836 and W. quadrifasciatus (Reuter, 1894; Hemerobius handschini Tjeder, 1957 and H. nitidulus Fabricius, 1777; and H. atrifrons McLachlan, 1868 and H. contumax Tjeder, 1932. Further studies are needed to test the possible synonymy of these species pairs or to determine if other genetic markers permit their discrimination. Our data highlight five cases of potential cryptic diversity within Bavarian Neuropterida: Nineta flava (Scopoli, 1763, Sympherobius pygmaeus (Rambur, 1842, Sisyra nigra (Retzius, 1783, Semidalis aleyrodiformis (Stephens, 1836 and Coniopteryx pygmaea Enderlein, 1906 are each split into two or three BINs. The present DNA barcode library not only allows the identification of adult and larval stages, but also provides valuable information for alpha-taxonomy, and for ecological and evolutionary research.

    Full Text Available La producción de ciencia es uno de los factores críticos de desarrollo para los países. Tradicionalmente, en Latinoamérica, los indicadores de desarrollo de la ciencia en términos de publicaciones e impacto se encuentran más alejados de los estándares de países con mayor desarrollo científico y tecnológico. Se evaluaron estos indicadores en general y específicamente en Psicología, mediante un análisis de la productividad latinoamericana de artículos científicos entre 1996 y 2008 en las bases SCOPUS y Web of Science de Thomson Reuters. Se identificaron las macrotendencias que han guiado el desarrollo de la Ciencia y Psicología en países e instituciones así como el impacto de las publicaciones. Los resultados sugieren que Brasil, México, Argentina, Chile y Colombia tienen los mejores indicadores en términos de producción e impacto, tanto en ciencia como en Psicología. Chile, Argentina y Brasil son los países más productivos por millón de habitantes.

    Craniovertebral junction is a complex anatomical location posing unique challenges to the surgical management of its pathologies. We aimed to identify the fifty most-cited articles that are dedicated to this field. A keyword search using the Thomson Reuters Web of Knowledge was conducted to identify articles relevant to the field of craniovertebral junction surgery. The articles were reviewed based on title, abstract, and methods, if necessary, and then ranked based on the total number of citations to identify the fifty most-cited articles. Characteristics of the articles were determined and analyzed. The earliest top-cited article was published in 1948. When stratified by decade, 1990s was the most productive with 16 articles. The most-cited article was by Anderson and Dalonzo on a classification of odontoid fractures. By citation rate, the most-cited article was by Herms and Melcher who described Goel's technique of atlantoaxial fixation using C1 lateral mass screws and C2 pedicle screws with rod fixation. Atlantoaxial fixation was the most common topic. The United States, Barrow Neurological Institute, and VH Sonntag were the most represented country, institute, and author, respectively. The significant majority of articles were designed as case series providing level IV evidence. Using citation analysis, we have provided a list of the most-cited articles representing important contributions of various authors from many institutions across the world to the field of craniovertebral junction surgery.

    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.

    2012-10-01

    From 1986 to 2003, substance abuse spending covered by private insurance fell in nominal dollars from $2444 million to $2239 million. The present study updated this literature to determine recent spending and utilization trends and provides a baseline for assessing the effects of recent health care policy changes. We used insurance claims data from Thomson Reuters MarketScan Commercial Claims and Encounters Database to study approximately 100 large, self-insured employers and millions of enrollees. We examined patterns in substance abuse treatment utilization and spending from 2001 through 2009. The study revealed that substance abuse spending remained a relatively constant share of all health spending, comprising about 0.4% of all health spending in 2009. The share of substance abuse spending on medications increased from 1% to 14%, but remained a small share of all health spending at about $2.45 per-member per-year. The study has implications for anticipating the effects of the federal parity law, in that the low share of substance abuse treatment means that even large increases in substance abuse utilization and spending are unlikely to have a significant impact on total health care costs.

    Full Text Available The objective of this paper is to empirically test one of Graham’s investment methods based on the net current asset value (NCAV. The NCAV is truly unique, and conservative, and commonly known as the net-net method.  The ratio of the net current asset value to market value (NCAV/MV was employed in this study to test a stock’s performance comparing to the performance of S&P 500 as the market index. We used all stocks in Portfolio123 whose raw data were supplied by Compustat, Standard & Poors, Capital IQ, and Reuters for the period of January 2, 1999 to August 31, 2012. The overall results show that the firms with high net current asset values outperform the market. These results are strong in the up market. It can be argued that the firms with a high NCAV/MV ratio are likely to move toward their fundamental value and generate high excess return because its stock prices are now undervalued. The implications of the study are: (a a positive NCAV/MV ratio may be a good indicator of the underpriced security; (b investing in the growth period and avoiding the downturn period leads investors to earn much higher returns from the firms with a high NCAV/MV ratio; and (c The NCAV/MV strategy requires a longer holding period of the portfolio in order to generate excess returns.

  18. Comparative performance of two air samplers for monitoring airborne fungal propagules

    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.

    Full Text Available Introduction Young onset dementia (YOD develops before 65 years of age and has specific age-related adverse consequences for quality of life (QoL. We systematically examined factors related to the QoL of people with YOD and their caregivers. Method This systematic review used the PRISMA methodology. The literature search was undertaken on July 5, 2015, using Cochrane, PubMed, SciELO, PsycINFO, Scopus and Thomson Reuters Web of Science electronic databases. The search keywords included early onset and young onset combined with, dementia, Alzheimer, vascular dementia, mixed dementia, frontotemporal dementia, quality of life, well-being and unmet needs. Nine studies were included. We revised objectives, study design, sample, instruments and results related to QoL. Results People with YOD rated their own QoL significantly higher than their caregivers. Greater awareness of disease among people with YOD is associated with better QoL in caregivers. A relationship was found between unmet needs and daytime activities, lack of companionship and difficulties with memory. Issues associated with unmet needs were prolonged time to diagnosis, available health services and lack of caregiver's own future perspective. Conclusion Consideration should be given to conducting investigations with more homogeneous samples and use of a clear concept of QoL. The present study highlights the need for future research in a wider range of countries, using instruments specifically for YOD. It would be interesting if studies could trace parallels with late onset dementia groups.

    2015-01-01

    Objectives Skull base endoscopy allows for minimal access approaches to the sinonasal contents and cranial base. Advances in endoscopic technique and applications have been published rapidly in recent decades. Setting We utilized an Internet-based scholarly database (Web of Science, Thomson Reuters) to query broad-based phrases regarding skull base endoscopy literature. Participants All skull base endoscopy publications. Main Outcome Measures Standard bibliometrics outcomes. Results We identified 4,082 relevant skull base endoscopy English-language articles published between 1973 and 2014. The 50 top-cited publications (n = 51, due to articles with equal citation counts) ranged in citation count from 397 to 88. Most of the articles were clinical case series or technique descriptions. Most (96% [49/51])were published in journals specific to either neurosurgery or otolaryngology. Conclusions A relatively small number of institutions and individuals have published a large amount of the literature. Most of the publications consisted of case series and technical advances, with a lack of randomized trials. PMID:26949585

    Full Text Available The paper discusses the relative frequency of topics of study in Italy, through the bibliography compiled by Emilio Corti, an assistant professor at the Zoology Institute of the University of Pavia, covering the period 1850–1933, compared with those obtained from the world literature from the database of Web of Knowledge by the Institute for Scientific Information (ISI of Thomson Reuters, for the period 1945–2005. Corti's bibliography, which has never been published, is kept in the Archives of the Pavia University Museum and comprises around 5500 papers covering various aspects of hydrobiology, fish and fish farming. Altogether what emerged was a methodical, complex study, providing a wealth of information even though made up solely of bibliographic references. Today it represents a significant source of consultation for anyone interested in the history of science and zoogeography. The comparison of Corti's topics with those of the 1945–2005 period confirmed (1 an overall increase in most research topics, (2 that some research topics, especially related to human activities, increased more than the others, (3 that the studies on malaria showed a peculiar trend, and that (4 organisms-based research did not diminish its importance through time.

  3. Impact of HIPAA's minimum necessary standard on genomic data sharing.

    2017-09-14

    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.GENETICS in MEDICINE advance online publication, 14 September 2017; doi:10.1038/gim.2017.141.

    The litigious nature of the American medical environment is a major concern for physicians, with an estimated annual cost of $10 billion. The purpose of this study is to identify causes of litigation in cases of testicular torsion and what factors contribute to verdicts or settlements resulting in indemnity payments. Publicly available jury verdict reports were retrieved from the Westlaw legal database (Thomson Reuters, New York, NY). In order to identify pertinent cases, we used the search terms "medical malpractice" and "testicular torsion" with date ranging from 2000 to 2013. Jury verdicts, depositions, and narrative summaries were evaluated for their medical basis, alleged malpractice, findings, and indemnity payment(s) (if any). Fifty-two cases were identified that were relevant to this study. Fifty-one percent of relevant cases were found in favor of the defendant physician, with the remaining 49% involving an indemnity payment (13% of which were settled). The most commonly sued medical providers were emergency physicians (48% of defendants), with urologists being second most common and making up 23% of the defendant pool. Emergency physicians were significantly more likely to make indemnity payments than urologists. Testicular torsion is a delicate condition and requires expertise in evaluation and treatment. When emergency physicians choose not to consult an urologist for possible torsion, they leave themselves open to litigation risk. When an urologist is involved in torsion litigation, they are rarely unsuccessful in their defense. Finally, ultrasound is no guarantee for success against litigation. Copyright © 2015 Elsevier Inc.

    Malpractice litigation contributes to rising health care costs in the United States. The role of expert witness testimony has been controversial in the past, with medical professional societies issuing statements regarding ethical obligations of physicians. Our objectives were to examine the relative qualifications of expert witnesses testifying on behalf of plaintiffs vs defendants. Analysis of expert witness and physician demographic data available on several databases. The Westlaw legal database (Thomson Reuters, New York, New York) was searched for otolaryngologist expert witness testimony. Length of experience, practice setting, and subspecialty training information were obtained from hospital, practice, departmental, and state licensing board sites. Scholarly impact was assessed using calculation of the h-index from the Scopus database. Plaintiff expert witnesses had significantly less experience than those testifying for defendants (31.8 vs 35.4 years, P = .047) and lower scholarly impact (h = 6.3 vs 10, P = .045). A significantly higher proportion of defendant witnesses were in academic practice (49.3% vs 31.7%, P = .042). No differences were detected in postresidency fellowship training patterns. Upon comparison of otolaryngologist expert witnesses, practitioners testifying on behalf of plaintiffs had statistically fewer years of experience, had a lower scholarly impact, and were less likely to work in an academic setting. Otolaryngologists who repeatedly served as expert witnesses were more likely to be testifying on behalf of plaintiffs than defendants. Professional societies need to frequently update guidelines on expert witness testimony and address the ethical obligations of practitioners.

    To describe a new database containing detailed annual information on firearm-related laws in place in each of the 50 US states from 1991 to 2016 and to summarize key trends in firearm-related laws during this time period. Using Thomson Reuters Westlaw data to access historical state statutes and session laws, we developed a database indicating the presence or absence of each of 133 provisions of firearm laws in each state over the 26-year period. These provisions covered 14 aspects of state policies, including regulation of the process by which firearm transfers take place, ammunition, firearm possession, firearm storage, firearm trafficking, and liability of firearm manufacturers. An examination of trends in state firearm laws via this database revealed that although the number of laws nearly doubled during the study period, there was substantial heterogeneity across states, leading to a widening disparity in the number of firearm laws. This database can help advance firearm policy research by providing 26 years of comprehensive policy data that will allow longitudinal panel study designs that minimize the limitations present in many previous studies.

    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

    This publication provides the first comprehensive DNA barcode data set for the Neuropterida of Central Europe, including 80 of the 102 species (78%) recorded from Bavaria (Germany) and three other species from nearby regions (Austria, France and the UK). Although the 286 specimens analyzed had a heterogeneous conservation history (60% dried; 30% in 80% EtOH; 10% fresh specimens in 95% EtOH), 237 (83%) generated a DNA barcode. Eleven species (13%) shared a BIN, but three of these taxa could be discriminated through barcodes. Four pairs of closely allied species shared barcodes including Chrysoperla pallida Henry et al., 2002 and C. lucasina Lacroix, 1912; Wesmaelius concinnus (Stephens, 1836) and W. quadrifasciatus (Reuter, 1894); Hemerobius handschini Tjeder, 1957 and H. nitidulus Fabricius, 1777; and H. atrifrons McLachlan, 1868 and H. contumax Tjeder, 1932. Further studies are needed to test the possible synonymy of these species pairs or to determine if other genetic markers permit their discrimination. Our data highlight five cases of potential cryptic diversity within Bavarian Neuropterida: Nineta flava (Scopoli, 1763), Sympherobius pygmaeus (Rambur, 1842), Sisyra nigra (Retzius, 1783), Semidalis aleyrodiformis (Stephens, 1836) and Coniopteryx pygmaea Enderlein, 1906 are each split into two or three BINs. The present DNA barcode library not only allows the identification of adult and larval stages, but also provides valuable information for alpha-taxonomy, and for ecological and evolutionary research.

    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.

    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.

    Many studies demonstrate that there is still a significant gender bias, especially at higher career levels, in many areas including science, technology, engineering, and mathematics (STEM). We investigated field-dependent, gender-specific effects of the selective pressures individuals experience as they pursue a career in academia within seven STEM disciplines. We built a unique database that comprises 437,787 publications authored by 4,292 faculty members at top United States research universities. Our analyses reveal that gender differences in publication rate and impact are discipline-specific. Our results also support two hypotheses. First, the widely-reported lower publication rates of female faculty are correlated with the amount of research resources typically needed in the discipline considered, and thus may be explained by the lower level of institutional support historically received by females. Second, in disciplines where pursuing an academic position incurs greater career risk, female faculty tend to have a greater fraction of higher impact publications than males. Our findings have significant, field-specific, policy implications for achieving diversity at the faculty level within the STEM disciplines. L. A. N.

    Vision Science is considered to be a quite developed discipline in Nepal, with much research currently in progress. Though the results of these endeavors are published in scientific journals, formal citation analyses have not been performed on works contributed by Nepalese vision scientists. To study Nepal's contribution to vision science literature in the database "Web of Science". The primary data source of this paper was Web of Science, a citation database of Thomas Reuters. All bibliometric analyses were performed with the help of Web of Science analysis service. In the current database of vision science literature, Nepalese authors contributed 112 publications to Web of Science, 95 of which were original articles. Pokharel GP had the highest number of citations among contributing authors of Nepal. Hennig A contributed the highest number of article as a first author. The Nepal Eye Hospital contributed the highest number of articles as an institution to the field of Vision Science. Currently, only two journals from Nepal including Journal of Nepal Medical Association (JAMA) are indexed in the Web of Science database (Sieving, 2012). To evaluate the total productivity of vision science literature from Nepal, total publication counts from national journals and articles indexed in other databases such as PubMed and Scopus must also be considered. © NEPjOPH.

    We screened 32 ophthalmology journals that had published articles during the period from 1850 through 1949 to identify top-cited articles in the field of ophthalmology (hereafter referred to as citation classics) using the online database Science Citation Index Expanded (Thompson Reuters, Chicago, Illinois). The 101 most frequently cited articles were published in 16 journals. Archives of Ophthalmology had the most top-cited articles (n = 31), followed by American Journal of Ophthalmology (n = 24) and Albrecht von Graefe's Archiv für Ophthalmologie (n = 9). These articles originated from 14 countries, with the United States publishing the majority (n = 58). Most of the citation classics are clinical studies on topics such as rubella cataract, retinopathy of prematurity, keratoconjunctivitis sicca, sympathetic ophthalmia, and the first report of eponymous diseases (eg, Leber hereditary optic neuropathy, Duane retraction syndrome, and Stargardt disease). A considerable number of these articles were ignored initially and for several decades after publication, but, like the classic fairy tale Sleeping Beauty, they have been rediscovered. Our study provides a historical perspective on the classic papers in the literature that are still influential in ophthalmology.

    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.

  16. Are shorter article titles more attractive for citations? Cross-sectional study of 22 scientific journals.

    To investigate the correlation between the length of the title of a scientific article and the number of citations it receives, in view of the common editorial call for shorter titles. Title and the number of citations to all articles published in 2005 in 22 arbitrarily chosen English-language journals (n=9031) were retrieved from citation database Scopus. The 2008 journal impact factors of these 22 journals were also retrieved from Thomson Reuters' Journal Citation Report (JCR). Assuming the article title length as the independent variable, and the number of citations to the article as the dependent variable, a linear regression model was applied. The slope of the regression line for some journals (n=6, when titles were measured in characters but 7 when titles were measured in words) was negative - none was significantly different from 0. The overall slope for all journals was 0.140 (when titles were measured in characters) and 0.778 (when titles were measured in words), which is significantly different from 0 (Ptitles received more citations - Spearman rho=0.266 - when titles were measured in characters, and rho=0.244 when titles were measured in words (P10 and for 2 out of 14 journals with impact factor titles seem to be associated with higher citation rates. This association is more pronounced for journals with high impact factors. Editors who insist on brief and concise titles should perhaps update the guidelines for authors of their journals and have more flexibility regarding the length of the title.

    Nesidiocoris tenuis (Reuter) (Hemiptera: Miridae) is an effective predator of multiple pests of vegetable crops, such as thrips, mites, aphids, whiteflies, leafminers. It is mass-reared and released for augmentative biocontrol programs mainly aimed at controlling whiteflies and Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae) in greenhouses and open field. We evaluated the lethal and sublethal toxicity upon N. tenuis adults of label doses of three insecticides (pyriproxyfen, spirotetramat, cypermethrin) and seven fungicides (benomyl, chlorothalonil, copper oxychloride, cyazofamid, fluopicolide + propamocarb hydrochloride (FPH), penconazol, trifloxystrobin) commonly used in various crops. Two exposure routes were tested: (i) contact with dry residues of insecticides or fungicides on tomato sprouts and (ii) multiple exposure to these chemicals via topical sprays on adults which foraged on treated sprouts; and fed on treated eggs of Ephestia kuehniella (Zeller) (Lepidoptera: Pyralidae) simultaneously. Mortality and reproductive capacity were investigated as indicators of lethal and sublethal effects on N. tenius. The tested insecticides and fungicides were all classified as harmless when predator was exposed only to the dry residues of each. However, the multiple exposure to either cypermethrin, benomyl, chlorothalonil, copper oxychloride or trifloxystrobin caused significant mortality of N. tenuis adults. Cypermethrin also significantly reduced its reproductive capacity. Interestingly, N. tenuis produced a higher number of progeny when exposed to fungicides penconazol and FPH in both exposure scenarios. Overall, findings suggest that the two insecticides, pyriproxyfen and spirotetramat but not cypermethrin, and all tested fungicides can be considered compatible with N. tenuis. PMID:29095873

    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.

    To evaluate the role of kangaroo mother care (KMC) on growth and breast feeding rates in very low birth weight (VLBW) neonates. A literature search was done to identify eligible studies using various electronic database searches including PubMed and EMBASE, various Web of Science including Scopus, Index Copernicus, African Index Medicus (AIM), Thomson Reuters (ESCI), Chemical Abstracts Service (CAS), SCIWIN (Scientific World Index), Google Scholar, Latin American and Caribbean Health Sciences Information System (LILACS), Index Medicus for the Eastern Mediterranean Region (IMEMR), Index Medicus for the South-East Asian Region (IMSEAR), and Western Pacific Region Index Medicus (WPRIM) and various clinical trial registries. Thirteen studies that evaluated the role of KMC in VLBW infants in improvement of growth outcome (weight/length/head circumference) or breast feeding rates as their primary or secondary outcome, were included in this systematic review. Seven studies evaluated both growth and breast feeding rates, four studies evaluated breast feeding rates and two studies evaluated growth outcome. All included studies except one either showed positive effect or no effect on growth and breast feeding rates. KMC has a positive effect on growth of the VLBW infants and also leads to increase in the breast-feeding rates. KMC should be an integral part of neonatal care and should be promoted as an essential newborn care component.

    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 ...

  1. 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.

    2016-01-01

    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 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.

La UNESCO, el Movimiento No Alineado y entidades tales como CIESPAL y el Instituto Latinoamericano de Estudios Transnacionales (ILET, con sede en México han denunciado sistemáticamente las maniobras de manipulación de la información, realizadas por estas agencias para defender la política externa de los países en los cuales tienen su sede. A partir de estas denuncias, surgió en varios puntos del Tercer Mundo la conciencia de que la dependencia no se produce solamente en las esferas políticas y económicas sino también en el ámbito socio - cultural, y que los países en desarrollo necesitan crear sus propios canales de comunicación si desean alcanzar un estado de real (o relativa independencia.

    2014-12-01

    Patterns of collaboration in social psychology from 2000 to 2010 were mapped to analyse the position of African authors in the international co-authorship network using bibliographic records from the Thomson Reuters Web of Knowledge. There are very few social psychologists working in Africa, with the majority of these located in South Africa. Indeed, some small European countries boast more social psychologists than the entire continent of Africa. African authors published less than their non-African collaborators, but had comparable status on joint publications. Co-authorship relationships between African researchers from different African countries were generally mediated by partners from other continents, and direct collaboration between non-compatriot African authors was very rare. The small size, and extremely sparse connection of the African co-authorship network, is likely to be an obstacle both in the development of social psychology as a universally relevant discipline and in the penetration of social psychological knowledge in Africa. © 2014 International Union of Psychological Science.

    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.

    Spinal cord stimulation (SCS) has been proven effective for multiple chronic pain syndromes. Over the past 40 years of use, the complication rates of SCS have been well defined in the literature; however, the incidence of one of the most devastating complications, spinal cord injury (SCI), remains largely unknown. The goal of the study was to quantify the incidence of SCI in both percutaneous and paddle electrode implantation. We conducted a retrospective review of the Thomson Reuter's MarketScan database of all patients that underwent percutaneous or paddle SCS implantation from 2000 to 2009. The main outcome measures of the study were the incidence of SCI and spinal hematoma within 30 days following operation. Overall 8326 patients met inclusion criteria for the study (percutaneous: 5458 vs. paddle: 2868). The overall incidence of SCI was 177 (2.13%) (percutaneous: 128 (2.35%) vs. paddle: 49 (1.71%), p = 0.0556). The overall incidence of spinal hematoma was 59 (0.71%) (percutaneous: 41 (0.75%) vs. paddle: 18 (0.63%), p = 0.5230). Our study shows that the overall incidence of SCI in SCS is low (2.13%), supporting that SCS is a safe procedure. No significant difference was found in the rates of SCI or spinal hematoma between the percutaneous and paddle groups. Further studies are needed to characterize the mechanisms of SCI in SCS and long-term outcomes in these patients. © 2015 International Neuromodulation Society.

  9. Mercury levels and human health in the Amazon Basin.

    2016-07-01

    Environmental mercury in the Amazon mostly originates from geochemical sources with some from artisanal gold mining (AGM). Geochemical-originated methylmercury (MeHg) reaches the aquatic food chain, ending up in fish. Inorganic Hg used in AGM is responsible for localised environmental contamination and occupational exposure of adults. In addition to this, iatrogenic ethylmercury (EtHg) derived from Thimerosal-containing vaccines (TCVs) exposes immunised infants. To understand Hg exposure in the Amazon in relation to environmental fish-MeHg exposure, occupational AGM activities and low-doses of TCV-EtHg. Medline and Thomson-Reuter Web of Science were searched to retrieve and select papers addressing Hg exposure and human health. Environmental-Hg studies addressed health effects associated with birth weight, infant linear growth and neurodevelopment, while, in adults, environmental and occupational studies addressed immune and neurological issues. No widespread clinical toxicity was reported due to fish-MeHg. However, mixed results associated with Hg exposure can be found. Reducing children's exposure to EtHg is possible using Thimerosal-free vaccines, but it is difficult to interfere with fish consumption without consequences to riverine subsistence populations. Policies to diminish Hg exposure should focus on controlling and/or curbing widespread use of Hg (in gold amalgamation) and promotion of Thimerosal-free vaccines for pregnant women and young children.

    Behçet disease (BD) is a chronic and multisystemic vasculitis characterized with recurrent oral and genital ulcers, uveitis, arthritis and skin manifestations. The highest prevalence of the disease has been reported in regions historically involved in the Silk Road routes. We aimed to analyse Behçet literature and evaluate whether there is a concordance between ancient Silk Road regions and the distribution of publication productivity. The bibliometric analysis of the publications published during 1980-2014 using Thomson Reuters Web of Science database was performed. We generated infographics of productivity and also analysed the correlations among economical productivities, technological advancement levels and humanity index and productivity performances of 78 countries in Behçet literature. Turkey ranked first in Behçet literature with 1837 articles followed by Japan and the USA. Turkey, Tunisia and Israel occupied the first three places in productivity. Significant correlations were noted between 2014 gross economic and technological indices and publication numbers of the countries. We found that European countries had high productivity, although they had low prevalence of BD. We detected no concordance between the productivity density of the countries and the ancient Silk Road routes. Most publications were reported from developed countries although undeveloped or developing countries had higher prevalence of BD. Physicians in undeveloped and developing countries should be supported and encouraged to perform novel studies on BD. © 2016 European Academy of Dermatology and Venereology.

    Full Text Available The objective of this paper is to determine the effect of International Financial Reporting Standards (IFRS as a new accounting reporting among Nigerian listed firms. This study uses book value, earnings and dividends to fill in the gap using a sample of 126 Nigerian listed firms in the stock market from 2009 to 2013 (pre and Post-IFRS adoption. Data was collected from Thompson Reuters, Bank scope DataStreams and annual reports. The study adopted Ohlson (1995 [Ohlson, J. (1995. Earnings, book-value, and dividends in equity valuation. Contemporary Accounting Research, 11(2, 661–687.] price model that has been frequently used in determining the quality of accounting information studies. 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. Therefore, findings of this study provide additional literature on the decreasing quality of accounting information in an emerging market setting like Nigeria. The study implication is to the policy makers, regulators, and government that accounting information do not provide value relevance among Nigerian listed firms after IFRS adoption.

  12. Measuring Scholastic Production by Dermatopathologists Using the H-Index: A Cross-Sectional Study.

    2017-10-16

    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.

    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.

    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.

  15. Overfitting Reduction of Text Classification Based on AdaBELM

    2017-07-01

    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.

    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.

    2016-01-01

    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.

    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 The main topic of this paper is a description of the generation of entropy at the end of the inflationary era. As a generalization of the present standard model of the Universe dominated by pressureless dust and a Lorentz invariant vacuum energy (LIVE, we first present a flat Friedmann universe model, where the dust is replaced with an ideal gas. It is shown that the pressure of the gas is inversely proportional to the fifth power of the scale factor and that the entropy in a comoving volume does not change during the expansion. We then review different measures of gravitational entropy related to the Weyl curvature conjecture and calculate the time evolution of two proposed measures of gravitational entropy in a LIVE-dominated Bianchi type I universe, and a Lemaitre-Bondi-Tolman universe with LIVE. Finally, we elaborate upon a model of energy transition from vacuum energy to radiation energy, that of Bonanno and Reuter, and calculate the time evolution of the entropies of vacuum energy and radiation energy. We also calculate the evolution of the maximal entropy according to some recipes and demonstrate how a gap between the maximal entropy and the actual entropy opens up at the end of the inflationary era.

    The X-ray structure for the type IIE EcoRII restriction endonuclease has been resolved [X.E. Zhou, Y. Wang, M. Reuter, M. Mucke, D.H. Kruger, E.J. Meehan and L. Chen. Crystal structure of type IIE restriction endonuclease EcoRII reveals an autoinhibition mechanism by a novel effector-binding fold. J. Mol. Biol. 335 (2004) 307-319.], but the structure of the R.EcoRII-DNA complex is still unknown. The aim of this article was to examine the structure of the pre-reactive R.EcoRII-DNA complex in solution by fluorescence spectroscopy. The structure for the R.EcoRII-DNA complex was resolved by determining the fluorescence resonance energy transfer (FRET) between two fluorescent dyes, covalently attached near the EcoRII recognition sites, that were located at opposite ends of a lengthy two-site DNA molecule. Analysis of the FRET data from the two-site DNA revealed a likely model for the arrangement of the two EcoRII recognition sites relative to each other in the R.EcoRII-DNA complex in the presence of Ca(2+) ions. According to this model, the R.EcoRII binds the two-site DNA and forms a DNA loop in which the EcoRII recognition sites are 20+/-10 A distant to each other and situated at an angle of 70+/-10 degrees.

    Full Text Available The objective of this study was to identify the determining factors of the effective tax rate (ETR of companies of Latin America in the period 2009 to 2013. Descriptive study was conduct through documentary research, with a quantitative approach of the data. The sample was made up of 500 companies, being 45 of Argentina, 171 of Brazil, 108 of Chile, 38 of Colombia, and Mexico's 71 67 of Peru. Whose data were collected in the database of Thompson Reuters ® and analyzed by means of panel data regression through the software STATA ®, having as dependent variable the Effective tax rate (ETR and independent variables size (TAM capital intensity (INTCAP, the intensity of inventory (INTINV, leverage (ALAV and profitability on assets (ROA. The results show that the size of companies positively influence presents significant about the ETR of Colombian companies. Capital intensity (INTCAP and the intensity of inventory (INTINV were not meaningful to determine the influence of the ETR in the countries analyzed. The leverage of the Argentine companies reveals a positive influence on the ETR, while for the Colombian companies this influence was significant not significant and negatively to the other countries. Profitability resulted in a negative influence to the Mexican and Peruvian companies, and not significant for the other countries to determine the influence on ETR. Denotes that there are differences regarding the determinants of tax burden in Latin American countries, which encourages further studies

    The present paper aims to perform a screening of native plants growing in Kettara mine-Marrakech (Southern Morocco) for its phytoremediation. Plants and soil samples were collected and analyzed for Pb, Zn, Cu and Cd concentrations at several sites in the mine. The results showed that the soil in the vicinity of Kettara mine is deficient in major elements and contain toxic levels of metals. Spontaneously growing native plants were botanically identified and then classified into 21 species and 14 families. Significant difference was observed among the average concentrations of four heavy metals (Pb, Zn, Cu and Cd) in plants (p ≤ 0.05). Six plants of 21 species namely Hammada scoparia (Pomel) Iljin, Hirschfeldia incana (L.) Lagreze-Fossat, Lamarckia aurea (L.) Moench, Calendula algeriensis Boiss. & Reuter, Aizoon hispanicum L. and Melilotus sulcata Desf. were considered as the best-performing specimens due to their high ability to accumulate multiple metals in their shoots and roots without sustaining toxicity. This was confirmed by the transfer factors generally higher than 1. Using the most common criteria to classify the hyperaccumulator plants, these species can be classified as new accumulator plants of many heavy metals and be potentially used as remediation tools of metal-contaminated sites.

    Full Text Available Testate amoebae have a great potential for use in scientific researches due to their ecological characteristics such as abundance, wealth, and generation time. In this way, this study aimed to present a scientometric analysis to describe the evolution of the different advances in researches on testate amoebae and identify a temporal pattern in this evolution. The literature review was based on papers indexed by Thomson Reuters (www.isiwebofknowledge.com and SciVerse Scopus (www.scopus.com. In total 562 papers were examined. Results showed a pattern of evolution in scientific studies, most with ecological approach with descriptive and predictive designs. At the global level, researches on testate amoebae progressed in both the number of articles published as well as in the areas studied, especially in Europe and North America. The low number of experimental studies and review articles can characterize the lack of more knowledge to be acquired, both from particular observations (descriptive studies as well as the observations noted sufficiently predictive of work. In Brazil, studies with testate amoebae are still developing, concentrated in only some regions, but the increased number of studies in recent years allows the prediction of the same overall patterns of advance for Brazilian researches. Thus, we conclude that these organisms are being increasingly used as a tool response in ecological studies.

    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 paper presents an intelligent information retrieval (IR) system based on automatic thesaurus construction for its applications of document clustering and classification. These two applications are the most influential and widely used fields amongst the IR research community. We apply two biologically inspired algorithms, i.e. genetic algorithm (GA) and neural network (NN), to these two fields. A fuzzy logic controller GA and an adaptive back-propagation NN are proposed in our study, which can validly overcome the problems existing in their archetypes, e.g. slow evolution and being prone to trap into a local optimum. Furthermore, a well-constructed thesaurus has been recognised as a valuable tool in the effective operation of clustering and classification. It solves the problem in document representation organised by a bag of words, where some important relationships between words, e.g. synonymy and polysemy, are ignored. To investigate how our IR system could be used effectively, we conduct experiments on four data sets from the benchmark Reuter-21578 document collection and 20-newsgroup corpus. The results reveal that our IR system enhances the performance in comparison with k-means, common GA, and conventional back-propagation NN.

    In 2011, Thomson-Reuters introduced the Book Citation Index (BCI) as part of the Science Citation Index (SCI). The interface of the Web of Science version 5 enables users to search for both "Books" and "Book Chapters" as new categories. Books and book chapters, however, were always among the cited references, and book chapters have been included in the database since 2005. We explore the two categories with both BCI and SCI, and in the sister databases for the social sciences (SoSCI) and the arts and humanities (A&HCI). Book chapters in edited volumes can be highly cited. Books contain many citing references, but are relatively less cited. We suggest that this may find its origin in the slower circulation of books then of journal articles. It is possible to distinguish scientometrically between monographs and edited volumes among the "Books". Monographs may be underrated in terms of citation impact or overrated using publication performance indicators because individual chapters are counted separately as ...

    An objective methodology to guide decisions by hospital pharmacy departments on the best use of clinical pharmacist personnel is described. To help determine the optimal deployment of state-licensed Clinical Pharmacist Specialist (CPS) staff, a task force led by the pharmacy department at University of North Carolina (UNC) Hospitals developed an objective approach to evaluating the relative need for and potential impact of CPS expertise within the medical center's many service units. After analyzing several years of patient census and medication-use data and using information from proprietary databases (Thomson Reuters) to calculate a "service-specific pharmacy intensity score" for each hospital service, the task force identified five staff-allocation metrics best suited to the medical center's service-based pharmacy coverage model. By applying the methodology, it was determined that CPS expertise was most needed in the UNC Hospitals adult medicine oncology service, the bone marrow transplant service, and the medical and neonatal intensive care units. The tool was initially used to validate the pharmacy department's existing human resource allocation and has since been used to guide budgeting for and deployment of newly added CPS positions. A novel tool to guide the application of pharmacy human resources incorporates the objective criteria of patient census, patient acuity, teaching involvement, drug expenditures, and use of high-risk medications. The tool can be used to determine the appropriate allocation and placement of clinical pharmacist resources in a service-based coverage model.

    Using traditional bibliometric indices such as the well-known journal impact factor (IFAC), as well as other more recently developed measures like the (journal) h-index and modifications, we assessed the impact of most prolific scientific journals in the field of animal and dairy science. To achieve this end, we performed a detailed investigation on the evaluation of journals quality, using a total of 50 journals selected from the category of "Agriculture, Dairy & Animal Science" included in the Thomson Reuters' (formerly Institute of Scientific Information, ISI) Web of Science. Our analysis showed that among the top journals in the field are the Journal of Dairy Research, the Journal of Dairy Science, and the Journal of Animal Science. In particular, the Journal of Animal Science, the most productive and frequently cited journal, has shown rapid development, especially in recent years. The majority of the top-tier, highly cited articles are those associated with the description of statistical methodology and the standard chemical analytical methodologies.

    In the United States of America, the nasometer was developed by Fletcher as an objective method for measuring nasality. There are no accepted normal values for comparable test materials regarding the German language. The aim of this study was the examination of the auditively normal nasality of Saxon-speaking people with the nasometer. The nasalance of 51 healthy Saxon-speaking test persons with auditively normal nasality was measured with a model 6200 nasometer (Kay-Elemetrics, U.S.A.). The text materials used were the vowels "a", "e", "i", "o", and "u", the sentences "Die Schokolade ist sehr lecker" ("The chocolate is very tasty") and "Nenne meine Mama Mimi" ("Name my mama Mimi"), and the texts of "North wind and sun", "A children's birthday", and an arbitrary selection from Strittmatter. The mean nasalance for the vowels was 17.7%, for the sentence containing no nasal sounds 13.0%, and for the sentence containing many nasal sounds 67.2%. The mean value of the texts was 33-41%. The results for the texts agreed well with the results of Reuter (1997), who examined people from the state of Brandenburg. A range from 20% to 55% is suggested as the normal value for nasalance in the German-speaking area.

    The quantitative study of the publication output (bibliometrics) deeply influences how scientific work is perceived (bibliometric visibility). Recently, new bibliometric indices and databases have been established, which may change the visibility of disciplines, institutions and individuals. This study examines the effects of the new indices on the visibility of Medical Informatics. By objective criteria, three sets of journals are chosen, two representing Medical Informatics and a third addressing Internal Medicine as a benchmark. The availability of index data (index coverage) and the aggregate scores of these corpora are compared for journal-related (Journal impact factor, Eigenfactor metrics, SCImago journal rank) and author-related indices (Hirsch-index, Egghes G-index). Correlation analysis compares the dependence of author-related indices. The bibliometric visibility depended on the research focus and the citation database: Scopus covers more journals relevant for Medical Informatics than ISI/Thomson Reuters. Journals focused on Medical Informatics' methodology were negatively affected by the Eigenfactor metrics, while the visibility profited from an interdisciplinary research focus. The correlation between Hirsch-indices computed on citation databases and the Internet was strong. The visibility of smaller technology-oriented disciplines like Medical Informatics is changed by the new bibliometric indices and databases possibly leading to suitably changed publication strategies. Freely accessible author-related indices enable an easy and adequate individual assessment.

    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.

    A satellite-DNA family (RUSI) has been isolated and characterized in Rumexinduratus Boiss and Reuter (Polygonaceae), an Iberian endemic polygamous sorrel. The RUSI repeats are 170 bp in length and approximately 68% AT-rich containing different variants of degenerate telomere motifs--(TT)(n)AN(GG)(n) -, a typical feature of subtelomeric DNA repeats adjacent to telomeres, which have been referred to as telomere-associated sequences or TASs. In fact, fluorescent in situhybridization showed that this satellite DNA is located in subtelomeric positions of most of the chromosomes of R. induratus, with some centromeric loci. PCR and Southern-blot hybridization assays for sequence conservation in the genus Rumex, indicated that the RUSI sequences are restricted to the genomes of R. induratus and R. scutatus, both species of the section Scutati, suggesting that they are recently evolved. Sequence variation within the two species is high (mean value of sequence differences between repeats of 15% for R. induratus and 7.5% for R. scutatus) and the degree of sequence differentiation between species is low with no species-specific variants, postulated to be due to slowed rates of spreading of sequence variants by molecular homogenizing mechanisms. Characteristics of RUSI sequences are discussed in the light of their chromosomal location and analyzed for their evolutionary and phylogenetic implications. Copyright 2009 S. Karger AG, Basel.

    A field survey was conducted in Ataulfo mango (Mangifera indica L.) orchards in Chiapas, Mexico, with the objective of determining the natural enemies of the Frankliniella complex species (Thysanoptera: Thripidae). Seven species of this genus feed and reproduce in large numbers during the mango flowering. Two representative orchards were selected: the orchard "Tres A" characterized by an intensive use of agrochemicals directed against thrips, and the orchard "La Escondida" that did not spray insecticides. During mango flowering, five inflorescences were randomly collected every 5 d in both orchards, for a total of 18 sampling dates. Results revealed the presence of 18 species of arthropods that were found predating on Frankliniella. There were 11 species in the families Aeolothripidae, Phlaeothripidae, Formicidae, Anthocoridae and Chrysopidae; and seven species of spiders in the families Araneidae, Tetragnathidae, and Uloboridae. Over 88% of predators were anthocorids, including, Paratriphleps sp. (Champion), Orius insidiosus (Say), Orius tristicolor (White), and O. perpunctatus (Reuter). The orchard that did not spray insecticides had a significantly higher number of predators suggesting a negative effect of the insecticides on the abundance of these organisms. © The Author 2015.

    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.

    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 impact factor without self-citation (6.08 ± 3.3) had a correlation (R: 0.672, P < 0.001) with the number of published items (248.6 ± 91.7). The number of articles and self-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.

    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

  2. Impact maturity times and citation time windows: The 2-year maximum journal impact factor

    2013-01-01

    Journal metrics are employed for the assessment of scientific scholar journals from a general bibliometric perspective. In this context, the Thomson Reuters journal impact factors (JIF) are the citation-based indicators most used. The 2-year journal impact factor (2-JIF) counts citations to one and two year old articles, while the 5-year journal impact factor (5-JIF) counts citations from one to five year old articles. Nevertheless, these indicators are not comparable among fields of science for two reasons: (i) each field has a different impact maturity time, and (ii) because of systematic differences in publication and citation behaviour across disciplines. In fact, the 5-JIF firstly appeared in the Journal Citation Reports (JCR) in 2007 with the purpose of making more comparable impacts in fields in which impact matures slowly. However, there is not an optimal fixed impact maturity time valid for all the fields. In some of them two years provides a good performance whereas in others three or more years are...

    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.

    The study developed information on behavioral health spending and utilization that can be used to anticipate, evaluate, and interpret changes in health care spending following implementation of the Mental Health Parity and Addiction Equity Act (MHPAEA). Data were from the Thomson Reuters' MarketScan database of insurance claims between 2001 and 2009 from large group health plans sponsored by self-insured employers. Annual rates in growth of total health spending and behavioral health spending and the contribution of behavioral health spending to growth in spending for all diseases were determined. Separate analyses examined behavioral health and total health spending by 135 employers in 2008 and 2009, and simulations were conducted to determine how increases in use of mental health services after implementation of parity would affect overall health care expenditures. Across the nine years examined, behavioral health expenditures contributed .3%, on average, to the total rate of growth in all health expenditures, a contribution that fell to .1%, on average, when prescription drugs were excluded. About 2% of employers experienced an increased contribution by behavioral health spending of more than 1%. More than 90% of enrollees used well below the maximum 30 inpatient days or outpatient visits typical of health insurance plans before parity. Simulations indicated that even large increases in utilization would increase total health care expenditures by less than 1%. The MHPAEA is unlikely to have a large effect on the growth rate of employers' health care expenditures. The data provide baseline information to further evaluate the implementation effect of the MHPAEA.

    Full Text Available In this research, two estimation algorithms for extracting cross-lingual news pairs based on machine learning from financial news articles have been proposed. 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.

  10. Two Wrongs Make a Right: Addressing Underreporting in Binary Data from Multiple Sources.

    2017-04-01

    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.

    Citation analysis was performed in order to identify the top 50 most cited articles pertaining to the field of primary spinal tumors. This collection of articles highlights important trends in the neurosurgical literature. We searched the Thomson Reuters Web of Knowledge in order to identify articles pertaining to primary tumors of the spine. Impertinent articles were removed. The top 50 most cited articles were identified. Thereafter, article characteristics were determined including article type, article topic, level of evidence, and citation rate. The selected articles were published between 1951 and 2008. The most productive year was 1997 with 6 publications. The top 50 articles were published in twenty-two different journals, most commonly in Neurosurgery (12), Journal of Neurosurgery (8), and Spine (6).

    Bibliometric analysis highlights key topics and publications that have shaped the understanding and management of esophageal cancer (EC). Here, the 100 most cited manuscripts in the field of EC are analyzed. The Thomson Reuters Web of Science database with the search terms 'esophageal cancer' or 'esophageal carcinoma' or 'oesophageal cancer' or 'oesophageal carcinoma' or 'gastroscopy' was used to identify all English language full manuscripts for the study. The 100 most cited papers were further analyzed by topic, journal, author, year, and institution. A total of 121,556 eligible papers were returned and the median (range) citation number was 406.5 (1833 to 293). The most cited paper focused on the role of perioperative chemotherpy in EC (1833 citations). Gastroenterology published the highest number of papers (n = 15, 6362 citations) and The New England Journal of Medicine received the most citations (n = 12, 12125 citations). The country and year with the greatest number of publications were the USA (n = 50), and 1998, 1999, and 2000 (n = 7). The most ubiquitous topic was the pathology of EC (n = 66) followed by management of EC (n = 54), and studies related to EC prognosis (n = 44). The most cited manuscripts highlighted the pathology, management, and prognosis of EC and this bibliometirc review provides the most influential references serving as a guide to popular research themes. © The Authors 2017.

    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 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 The relationship between the degree of internationalization and performance of multinational corporations (MNCs has been widely studied in international business literature. However, most studies have been performed with companies from developed countries. In order to contribute to the development of the theory of internationalization-performance, this study examines this relationship in the universe of MNCs from developing economies. The main objective of this study is to analyze if these MNCs’ international expansion strategies are being translated in an efficient and effective way in terms of managing company business. Our sample includes 33 of the 100 most highly internationalized multinational companies (MNCs from developing economies, and the information was collected over a 6 year period (2004-2009. Data were obtained from two sources: (a the United Nations Conference on Trade and Development (UNCTAD; and (b Thomson Reuters Datastream. Multiple regression analysis, Ordinary Least Squares (OLS method, and panel data analysis found a negativelinear relationship between the degree of internationalization and developing economy MNC performance,indicating that the higher the degree of internationalization, the lower MNC performance tends to be.

    Full Text Available Este trabajo plantea un análisis sobre el uso de los medios de comunicación en las relaciones de fuerza entre Estados. Así, comienza con una descripción del Informe MacBride de 1980, el mayor documento en el seno de Naciones Unidas que refleja la problemática y que a 35 años de publicarse mantiene su vigencia en muchos puntos. Enfocándose en las agencias de noticias, se observa el origen de ellas y su "reparto" del mundo sobre la base del sistema colonial de principios de siglo xx. Después se hará un breve recorrido histórico para finalizar con las más fuertes en la actualidad: UPI, AP, AFP y Reuters. Finalmente, se mencionan propuestas que han tomado fuerzas en las últimas décadas como las agencias Xinhua (Nueva China, ITAR-TASS y la señal televisiva Al Jazzera. Estas últimas en relación con un cambio de fuerzas a nivel mundial. Como decía el Informe McBride, nos dirigimos "hacia un nuevo orden mundial de la información y la comunicación". A diferencia de lo que proponía, no será más justo y eficiente sino más diverso y multipolar.

    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.

  17. Metaphorical scenarios in business science discourse

    Full Text Available Metaphor has been shown to play an important role in business science discourse. Yet, previous corpus-based studies only investigated a pre-selected list of metaphoric expressions, potentially rendering the analysis incomplete. Furthermore, some studies which only focused on lexis did not analyse how the lexical items may construct business concepts in terms of scenarios. The purpose of this research is to investigate metaphor used to construct business concepts in business research articles. 42 business research articles published in 2009-2010 from five journals ranked in the top-ten according to the 2007 journal impact factors (Thompson Reuters, 2008 constitute the data of this study. Semantic annotation software USAS (Rayson, 2008 was used to assist in the retrieval of metaphoric expressions. Furthermore, manual analysis of concordances was done to find metaphorical expressions that had not been captured by the semantic tags. The analysis of these metaphoric expressions was based on Conceptual Metaphor Theory (Lakoff & Johnson, 1980 and Metaphor Scenario (Musolff, 2006. Data analysis indicates that metaphor constructs business concepts as scenarios which have participants performing actions to reach their goal according to the SOURCE-PATH-GOAL schema of the source domains. At the centre of these scenarios, the BOUNDED SPACE source domain serves as a conceptual space or a setting for each scenario. Other source domains, which are WAR, SPORT, GAME, JOURNEY, MACHINE, LIVING ORGANISM, BUILDING and PHYSICAL FORCES, project the scenarios onto the space, forming interconnected and coherent scenarios of business discourse

  18. Defining and evaluating classification algorithm for high-dimensional data based on latent topics.

    Directory of Open Access Journals (Sweden)

    Le Luo

    Full Text Available Automatic text categorization is one of the key techniques in information retrieval and the data mining field. The classification is usually time-consuming when the training dataset is large and high-dimensional. Many methods have been proposed to solve this problem, but few can achieve satisfactory efficiency. In this paper, we present a method which combines the Latent Dirichlet Allocation (LDA algorithm and the Support Vector Machine (SVM. LDA is first used to generate reduced dimensional representation of topics as feature in VSM. It is able to reduce features dramatically but keeps the necessary semantic information. The Support Vector Machine (SVM is then employed to classify the data based on the generated features. We evaluate the algorithm on 20 Newsgroups and Reuters-21578 datasets, respectively. The experimental results show that the classification based on our proposed LDA+SVM model achieves high performance in terms of precision, recall and F1 measure. Further, it can achieve this within a much shorter time-frame. Our process improves greatly upon the previous work in this field and displays strong potential to achieve a streamlined classification process for a wide range of applications.

    Full Text Available Nesidiocoris tenuis (Reuter (Hemiptera: Miridae is an effective predator of multiple pests of vegetable crops, such as thrips, mites, aphids, whiteflies, leafminers. It is mass-reared and released for augmentative biocontrol programs mainly aimed at controlling whiteflies and Tuta absoluta (Meyrick (Lepidoptera: Gelechiidae in greenhouses and open field. We evaluated the lethal and sublethal toxicity upon N. tenuis adults of label doses of three insecticides (pyriproxyfen, spirotetramat, cypermethrin and seven fungicides (benomyl, chlorothalonil, copper oxychloride, cyazofamid, fluopicolide + propamocarb hydrochloride (FPH, penconazol, trifloxystrobin commonly used in various crops. Two exposure routes were tested: (i contact with dry residues of insecticides or fungicides on tomato sprouts and (ii multiple exposure to these chemicals via topical sprays on adults which foraged on treated sprouts; and fed on treated eggs of Ephestia kuehniella (Zeller (Lepidoptera: Pyralidae simultaneously. Mortality and reproductive capacity were investigated as indicators of lethal and sublethal effects on N. tenius. The tested insecticides and fungicides were all classified as harmless when predator was exposed only to the dry residues of each. However, the multiple exposure to either cypermethrin, benomyl, chlorothalonil, copper oxychloride or trifloxystrobin caused significant mortality of N. tenuis adults. Cypermethrin also significantly reduced its reproductive capacity. Interestingly, N. tenuis produced a higher number of progeny when exposed to fungicides penconazol and FPH in both exposure scenarios. Overall, findings suggest that the two insecticides, pyriproxyfen and spirotetramat but not cypermethrin, and all tested fungicides can be considered compatible with N. tenuis.

    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.

    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.

    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.

    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.

    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.

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.

    Scientific publication in academic literature is a key venue in which the U.S. Department of Defense's Global Emerging Infections Surveillance and Response System (GEIS) program disseminates infectious disease surveillance data. Bibliometric analyses are tools to evaluate scientific productivity and impact of published research, yet are not routinely used for disease surveillance. Our objective was to incorporate bibliometric indicators to measure scientific productivity and impact of GEIS-funded infectious disease surveillance, and assess their utility in the management of the GEIS surveillance program. Metrics on GEIS program scientific publications, project funding, and countries of collaborating institutions from project years 2006 to 2012 were abstracted from annual reports and program databases and organized by the six surveillance priority focus areas: respiratory infections, gastrointestinal infections, febrile and vector-borne infections, antimicrobial resistance, sexually transmitted infections, and capacity building and outbreak response. Scientific productivity was defined as the number of scientific publications in peer-reviewed literature derived from GEIS-funded projects. Impact was defined as the number of citations of a GEIS-funded publication by other peer-reviewed publications, and the Thomson Reuters 2-year journal impact factor. Indicators were retrieved from the Web of Science and Journal Citation Report. To determine the global network of international collaborations between GEIS partners, countries were organized by the locations of collaborating institutions. Between 2006 and 2012, GEIS distributed approximately US $330 million to support 921 total projects. On average, GEIS funded 132 projects (range 96-160) with $47 million (range $43 million-$53 million), annually. The predominant surveillance focus areas were respiratory infections with 317 (34.4%) projects and $225 million, and febrile and vector-borne infections with 274 (29

    Full Text Available CONTEXT AND OBJECTIVE: Increased frequency of retractions has recently been observed, and retractions are important events that deserve scientific investigation. This study aimed to characterize cases of retraction within general and internal medicine in a high-profile database, with interest in the country of origin of the article and the impact factor (IF of the journal in which the retraction was made. DESIGN AND SETTING: This study consisted of reviewing retraction notes in the Thomson-Reuters Web of Knowledge (WoK indexing database, within general and internal medicine. METHODS: The retractions were classified as plagiarism/duplication, error, fraud and authorship problems and then aggregated into two categories: "plagiarism/duplication" and "others." The countries of origin of the articles were dichotomized according to the median of the indicator "citations per paper" (CPP, and the IF was dichotomized according to its median within general and internal medicine, also obtained from the WoK database. These variables were analyzed using contingency tables according to CPP (high versus low, IF (high versus low and period (1992-2002 versus 2003-2014. The relative risk (RR and 95% confidence interval (CI were estimated for plagiarism/duplication. RESULTS: A total of 86 retraction notes were identified, and retraction reasons were found for 80 of them. The probability that plagiarism/duplication was the reason for retraction was more than three times higher for the low CPP group (RR: 3.4; 95% CI: [1.9-6.2], and similar results were seen for the IF analysis. CONCLUSION: The study identified greater incidence of plagiarism/duplication among retractions from countries with lower scientific impact.

    Full Text Available Background: Web of Science (WoS is an online academic citation index provided by Thomson Reuters which supplies valuable bibliometric information for comparing impact of specific author, organization, or country in science production. The aim of this study was to compare toxicology publications of Iran and Turkey indexed in WoS from bibliometric point of view. Methods: The WoS database was queried based on keywords “Iran” and “Turkey” separately in the “Address” field and refined by “Toxicology” as a category. All records were transferred to Microsoft Excel® application. The dataset were analyzed from different perspectives, such as publication years, number of references and citations, authorship pattern, publications types, affiliated organizations, core subject areas and journals. Results: There were 1178 and 2240 publications that met the criteria during 1993-2011 for Iran and Turkey, respectively. Less than 2% of authors had published more than 25% of all toxicology papers in both countries. The average number of citation per article was about 3.48 for Iranian and 6.73 for Turkish papers. By the time of the analysis, 54.3% of Iranian and 31.6% of Turkish articles had not received any citation. Conclusion: This analysis reveals that top Iranian toxicologists had a better performance than their Turkish counterparts but overall authorship pattern was well-distributed among Turkish researchers and organizations. If Iranian authors desire to achieve first rank of toxicology articles in the Middle East region by 2025, they must try to increase the quantity and quality of their international publications.

    OBJECTIVE Despite the growing neurosurgical literature, a subset of pioneering studies have significantly impacted the field of metastatic spine disease. The purpose of this study was to identify and analyze the 100 most frequently cited articles in the field. METHODS A keyword search using the Thomson Reuters Web of Science was conducted to identify articles relevant to the field of metastatic spine disease. The results were filtered based on title and abstract analysis to identify the 100 most cited articles. Statistical analysis was used to characterize journal frequency, past and current citations, citation distribution over time, and author frequency. RESULTS The total number of citations for the final 100 articles ranged from 74 to 1169. Articles selected for the final list were published between 1940 and 2009. The years in which the greatest numbers of top-100 studies were published were 1990 and 2005, and the greatest number of citations occurred in 2012. The majority of articles were published in the journals Spine (15), Cancer (11), and the Journal of Neurosurgery (9). Forty-four individuals were listed as authors on 2 articles, 9 were listed as authors on 3 articles, and 2 were listed as authors on 4 articles in the top 100 list. The most cited article was the work by Batson (1169 citations) that was published in 1940 and described the role of the vertebral veins in the spread of metastases. The second most cited article was Patchell's 2005 study (594 citations) discussing decompressive resection of spinal cord metastases. The third most cited article was the 1978 study by Gilbert that evaluated treatment of epidural spinal cord compression due to metastatic tumor (560 citations). CONCLUSIONS The field of metastatic spine disease has witnessed numerous milestones and so it is increasingly important to recognize studies that have influenced the field. In this bibliographic study the authors identified and analyzed the most influential articles in the

    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.

    Bibliometric review of the literature. To identify and analyze the top 100 cited articles in spinal deformity surgery. The field of spinal deformity surgery is an ever-growing and complex field that owes its development to the work and visions of many dedicated individuals. The authors searched the Thomson Reuters Web of Knowledge for citations of all articles relevant to scoliosis and spinal deformity surgery. The number of citations, authorship, year, journal, and country and institution of publication were recorded for each article. The most cited article was the 2001 work by Lenke et al. describing a new 2-dimensional classification system of adolescent idiopathic scoliosis used to determine the appropriate vertebral levels to be included in an arthrodesis. The second most cited was Harrington's 1962 article describing the first instrumented method for the treatment of scoliosis. The third most cited article was the 1983 study by King et al. recommending specific vertebral levels for inclusion into spinal arthrodesis. Most articles originated in the United States (62), and most were published in Spine (32). Most were published in the 1990s (28), and the 3 most common topics, in descending order, were adolescent idiopathic scoliosis (28), spinal instrumentation (18), and surgical complications (5). Author Suk had 5 articles in the top 100 list, whereas authors Kim, Liljenqvist, Lonstein, and Weinstein had 3 each. Washington University in St. Louis had 7 articles in the top 100 list. This report's identification of the 100 classic articles in spinal deformity surgery allows insight into the development and trends of this challenging subspecialty of spine surgery. Furthermore, this article identifies individuals who have contributed the most to the advancement of spinal deformity surgery and the body of knowledge used to guide evidence-based clinical decision making in spinal deformity surgery today.

    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.

    The number of citations an article receives has been used as a marker of its influence within a surgical specialty. Currently, there is limited citation analysis in oral and maxillofacial trauma surgery. The purpose of this study was to determine the 100 most cited articles in facial trauma surgery and their characteristics. Articles were identified from the Science Citation Index of the Institute for Scientific Information using the Thomson Reuters Web of Science search engine. All articles until 2015 were included. Then, the 100 most cited articles were assessed for title, author, journal, country of origin, and number of citations. A citation index (number of citations received per year) also was calculated. The 100 most cited articles in facial trauma received 9,933 citations (range, 66 to 297). They were published from 1942 through 2008, with 1990 through 1999 being the commonest decade. Articles were cited on average 4.6 times per year. Articles were published in 28 different journals, with impact factors ranging from 0.94 to 35.3. Most articles were observational research studies. These findings reflect the attention that articles have received during the past half century in oral and maxillofacial trauma research, shedding light on often-read articles in this field. In addition to current bibliometric indices, it could provide a useful evidence base for facial surgeons, represent key educational material for aspiring trainees, and be used to help guide future research efforts.

    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.

    Neuroimaging data emphasize that older adults often show greater extent of brain activation than younger adults for similar objective levels of difficulty. A possible interpretation of this finding is that older adults need to recruit neuronal resources at lower loads than younger adults, leaving no resources for higher loads, and thus leading to performance decrements [Compensation-Related Utilization of Neural Circuits Hypothesis; e.g., Reuter-Lorenz, P. A., & Cappell, K. A. Neurocognitive aging and the compensation hypothesis. Current Directions in Psychological Science, 17, 177-182, 2008]. The Compensation-Related Utilization of Neural Circuits Hypothesis leads to the prediction that activation differences between younger and older adults should disappear when task difficulty is made subjectively comparable. In a Sternberg memory search task, this can be achieved by assessing brain activity as a function of load relative to the individual's memory span, which declines with age. Specifically, we hypothesized a nonlinear relationship between load and both performance and brain activity and predicted that asymptotes in the brain activation function should correlate with performance asymptotes (corresponding to working memory span). The results suggest that age differences in brain activation can be largely attributed to individual variations in working memory span. Interestingly, the brain activation data show a sigmoid relationship with load. Results are discussed in terms of Cowan's [Cowan, N. The magical number 4 in short-term memory: A reconsideration of mental storage capacity. Behavioral and Brain Sciences, 24, 87-114, 2001] model of working memory and theories of impaired inhibitory processes in aging.

    Obsessive-compulsive disorder is a psychiatric disorder stated as one of the most debilitating diseases in the developedworld. However, not much is known about how this disease impairs patients' quality of life in children. We conducted a research in PubMed and Thomson Reuters Web Of Science using the following terms: 'Quality of life', 'Obsessive-compulsive disorder', 'Child', 'Pediatrics' and 'Adolescent'. Of the 138 papers retrieved with this search, five articles corresponded to the aim of this review. We analyzed quality of life in children with obsessive-compulsive disorder comparing with general population and searching the relation with other clinical variables such as sex, age, comorbidities, symptoms dimension, symptoms severity, family accommodation and quality of life. Albeit studies results not being concordant regarding the different dimensions analyzed, our findings pointed to an overall decrease of quality of life in children with obsessive-compulsive disorder. The presence of co-morbidities, symptoms severity and obsessions with harm/aggression content are the variables that have a higher influence in quality of life levels. The small number of articles found and the fact that their methodology was extremely heterogeneous made it difficult to state robust conclusions. Despite that, our findings agree with other studies in adults. Quality of life in children and adolescents with obsessive-compulsive disorder must be better explored in future researches. We suggest the introduction of quality of life as a routinely used instrument in patient's assessment and in treatment response evaluation.

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

    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.

    Deep brain stimulation (DBS) is a well-established modality for the treatment of advanced Parkinson disease (PD). Recent studies have found DBS plus best medical therapy to be superior to best medical therapy alone for patients with PD and early motor complications. Although no specific age cutoff has been defined, most clinical studies have excluded patients older than 75 years of age. We hypothesize that increasing age would be associated with an increased number of postoperative complications. To evaluate the stepwise effect of increasing age (in 5-year epochs) on short-term complications following DBS surgery. A large, retrospective cohort study was performed using the Thomson Reuters MarketScan national database that examined 1757 patients who underwent DBS for PD during the period from 2000 to 2009. Primary measures examined included hospital length of stay and aggregate and individual complications within 90 days following surgery. Multivariate logistic regression analysis was used to calculate complication-related odds ratios (ORs) for each 5-year age epoch after controlling for covariates. Overall, 132 of 1757 patients (7.5%) experienced at least 1 complication within 90 days, including wound infections (3.6%), pneumonia (2.3%), hemorrhage or hematoma (1.4%), or pulmonary embolism (0.6%). After adjusting for covariates, we found that increasing age (ranging from patients with PD (>75 years) who were selected to undergo DBS surgery showed a similar 90-day complication risk (including postoperative hemorrhage or infection) compared with younger counterparts. Our findings suggest that age alone should not be a primary exclusion factor for determining candidacy for DBS. Instead, a clear focus on patients with medication-refractory and difficult to control on-off fluctuations with preserved cognition, regardless of age, may allow for an expansion of the traditional therapeutic window.

  3. Trophic relationships between predators, whiteflies and their parasitoids in tomato greenhouses: a molecular approach.

    The whiteflies Bemisia tabaci Gennadius and Trialeurodes vaporariorum (Westwood) (Hemiptera: Aleyrodidae) are two of the main pests in tomato crops. Their biological control in Mediterranean IPM systems is based on the predators Macrolophus pygmaeus (Rambur) and Nesidiocoris tenuis Reuter (Hemiptera: Miridae), as well as on the parasitoids Eretmocerus mundus (Mercet) and Encarsia pergandiella Howard (Hymenoptera: Aphelinidae). These natural enemies may interact with each other and their joint use could interfere with the biological control of those whitefly pests. Analysis of predator-prey interactions under field conditions is therefore essential in order to optimize whitefly control. Species-specific polymerase chain reaction (PCR)-primers were designed to detect DNA fragments of these whiteflies and parasitoids within both predator species in tomato greenhouses. We demonstrated that both predators feed on both whitefly species, as well as on both parasitoids under greenhouse conditions. Prey molecular detection was possible where prey abundance was very low or even where predation was not observed under a microscope. Whitefly DNA detection was positively correlated with adult whitefly abundance in the crop. However, a significant relationship was not observed between parasitoid DNA detection and the abundance of parasitoid pupae, even though the predation rate on parasitoids was high. This unidirectional intraguild predation (predators on parasitoids) could potentially reduce their combined impact on their joint prey/host. Prey molecular detection provided improved detection of prey consumption in greenhouse crops, as well as the possibility to identify which prey species were consumed by each predator species present in the greenhouse, offering a blueprint with wider applicability to other food webs.

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

    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.

    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.

    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."

  7. Characterizing social media metrics of scholarly papers: the effect of document properties and collaboration patterns.

    Directory of Open Access Journals (Sweden)

    Stefanie Haustein

    Full Text Available 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.

Our objective was to assess the different metrics reported for relative impact and cost for journals relevant to gynecologic oncology. 55 journals were evaluated for Impact Factor (IF), 5 Year IF, Immediacy Index, Cited Half Life, Eigenfactor (EF) Score, Article Influence (AI) scores and subscription costs obtained from publisher information. CA-A Cancer Journal for Clinicians had the highest IF (101.78) & AI (24.502). The top EF cancer-specific journals were the Journal of Clinical Oncology, Cancer Research, Clinical Cancer Research and Oncogene. Rankings for Gynecologic Oncology (409 articles, 18,243 citations) were IF = 3.929, 43/55, EF = 0.038, 28/55, and AI = 1.099, 44/55, all higher than the previous year. The IF improved from the 5 year IF in 31 journals, including Gynecologic Oncology, 29/31. Subscription costs for Gynecologic Oncology compared favorably to other journals. The high utilization of review information in CA-A Cancer Journal for Clinicians and Nature Review Cancer illustrated by the IF coupled with a relatively low number of articles and short cited half life indicates that they serve as a leading source of quoted cancer statistics (CA-A Cancer Journal for Clinicians). Rankings for Gynecologic Oncology and the International Journal of Gynecologic Cancer have improved. Regardless of specialty size, the Impact Factor for Gynecologic Oncology is respectably strong. The decreased IF in 44% of the journals may reflect the international economy's effect on cancer research. Copyright © 2013 Elsevier Inc. All rights reserved.

    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.

    The taxonomic position of Bifidobacterium stercoris Eg1(T) ( = JCM 15918(T)) based on comparative 16S rRNA gene and hsp60 sequence analyses was found to be controversial, as the strain showed high similarity to the type strain of Bifidobacterium adolescentis, CCUG 18363(T). Therefore, the relationship between the two species was investigated by a taxonomic study that included, in addition to re-evaluation of the 16S rRNA gene sequence, determination of DNA-DNA binding and multilocus sequence analysis (MLSA) of housekeeping genes encoding the DNA-directed RNA polymerase B subunit (rpoC), putative xylulose-5-phosphate/fructose-6-phosphate phosphoketolase (xfp), elongation factor EF-G (fusA), 50S ribosomal protein L2 (rplB) and DNA gyrase B subunit (gyrB). Comparative 16S rRNA gene sequence analysis showed relatively high similarity (98.9 %) between B. stercoris KCTC 5756(T) and B. adolescentis ATCC 15703(T). MLSA revealed close relatedness between B. stercoris KCTC 5756(T) and B. adolescentis CCUG 18363(T), with 99.3-100 % similarity between the rpoC, xfp, fusA, rplB and gyrB gene sequences. In addition, relatively high dnaJ1 gene sequence similarity of 97.7 % was found between the strains. Similar phenotypes and a high DNA-DNA binding value (78.9 %) confirmed that B. stercoris and B. adolescentis are synonymous. Based on these results, it is proposed that the species Bifidobacterium stercoris Kim et al. 2010 should be reclassified as a later heterotypic synonym of Bifidobacterium adolescentis Reuter 1963 (Approved Lists 1980).

    Full Text Available Objectives – To compare PubMed and Google Scholar results for content relevance and article qualityDesign – Bibliometric study.Setting – Department of Internal Medicine at Texas Tech University Health Sciences Center.Methods – Four clinical searches were conducted in both PubMed and Google Scholar. Search methods were described as “real world” (p. 216 behaviour, with the searchers familiar with content, though not expert at retrieval techniques. The first 20 results from each search were evaluated forrelevance to the initial question, as well as for quality.Relevance was determined based on one author’s subjective assessment of information in the title and abstract, when available, and then tested by two other authors, with discrepancies discussed and resolved. Items were assigned to one of three categories: relevant, possibly relevant, and not relevant to the question, with reviewer agreement measured using a weighted kappa statistic. The quality of items found to be ‘relevant’ and ‘possibly relevant’ was measured by impact factor ratings from Thomsen Reuters (ISI Web of Knowledge, when available, as well as information obtained by SCOPUS on the number of times items were cited.Main Results – Google Scholar results were judged to be more relevant and of higher quality than results obtained from PubMed. Google Scholar results are also older on average, while PubMed retrieved items from a larger number of unique journals.Conclusion – In agreement with earlier research, the authors recommended that searchers use both PubMed and Google Scholar to improve on the quality and relevance of results. Searches in the two resources identify unique items based upon the ranking algorithms involved.

    Background & Aims Gastrointestinal (GI) diseases account for substantial morbidity, mortality and cost. Statistical analyses of the most recent data are necessary to guide GI research, education and clinical practice. We estimate the burden of GI disease in the US. Methods We collected information on the epidemiology of GI diseases (including cancers) and symptoms, along with data on resource utilization, quality of life, impairments to work and activity, morbidity, and mortality. These data were obtained from the National Ambulatory Medical Care Survey; National Health and Wellness Survey; Nationwide Inpatient Sample; Surveillance, Epidemiology, and End Results Program; National Vital Statistics System; Thompson Reuters MarketScan®; Medicare; Medicaid; and the Clinical Outcomes Research Initiative’s National Endoscopic Database. We estimated endoscopic use and costs and examined trends in endoscopic procedure. Results Abdominal pain was the most common gastrointestinal symptom that prompted a clinic visit (15.9 million visits). Gastroesophageal reflux was the most common GI diagnosis (8.9 million visits). Hospitalizations and mortality from Clostridium difficile infection have doubled in the last 10 years. Acute pancreatitis was the most common reason for hospitalization (274,119 discharges). Colorectal cancer accounted for more than half of all GI cancers and was the leading cause of GI-related mortality (52,394 deaths). There were 6.9 million upper, 11.5 million lower, and 228,000 biliary endoscopies performed in 2009. The total cost for outpatient gastrointestinal endoscopy examinations was $32.4 billion. Conclusions GI diseases are a source of substantial morbidity, mortality and cost in the US. PMID:22885331

    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.

    Poisons information is accessed around the clock in the British Isles from six centres of which two are in Ireland at Dublin and Belfast accompanied by consultant toxicologist advisory service. The numbers of calls in Ireland are down to about 40 per day due to easy access to online data bases. Access to Toxbase, the clinical toxicology database of the National Poisons Information Service is available to National Health Service (NHS) health professionals and to Emergency Departments and Intensive Care units in the Republic of Ireland. There are 59 Toxbase users in the Republic of Ireland and 99 % of activity originates in Emergency Departments. All United States Poison Control Centres primarily use Poisindex which is a commercial database from Thomson Reuters. Information on paracetamol, diazepam, analgesics and psycho-active compounds are the commonest queries. Data from telephone and computer accesses provide an indicator of future trends in both licit and illicit drug poisons which may direct laboratory analytical service developments. Data from National Drug-Related Deaths Index is the most accurate information on toxicological deaths in Ireland. Laboratory toxicology requirements to support emergency departments are listed. Recommendations are made for a web-based open access Toxbase or equivalent; for a co-location of poisons information and laboratory clinical toxicology; for the establishment of a National Clinical Toxicology Institute for Ireland; for a list of accredited medical advisors in clinical toxicology; for multidisciplinary case conferences in complex toxicology cases for coroners; for the establishment of a national clinical toxicology referral out-patients service in Ireland.

    The objective of the current research was to examine the current epidemiology of traumatic brain injury (TBI); to determine the effects of geographic region, co-morbidities, year of injury, injury severity, and demographics on hospital costs, length of stay (LOS), and mortality. All subjects were drawn from the Thomason Reuters MarketScan(®) database. Statistical methods used included descriptive analysis, bivariate analysis, logistic regression, and the Geographic Information System (GIS) software, ArcMap. We studied 76,313 patients with TBI from 2004 to 2009 (52,721 with commercial insurance and 23,592 with Medicare) from the MarketScan database. As age increased, mortality rate and median LOS increased. The median hospital costs for adults were the highest ($13,000 for ages 18-64) compared with children ($8000 for age 0-14) and elderly persons ($9000 for age ≥ 65). The mortality rate for the elderly population has decreased slightly (11.1% in 2004 to 9.9% in 2009 for men, and 7.0% to 6.9% for women); however, their hospital costs have increased significantly ($6899 in 2004 to $11,567 in 2009 for men; $6784 to $9782 for women). Concerning the impact of geography, the western United States (e.g., Washington and California) had lower mortality rates and higher median costs while the southeast United States had the highest mortality and mixed median costs. Both overall mortality and median LOS have remained relatively stable over the years. Hospital cost, however, has increased for the elderly population even after accounting for the inflation. There is significant geographic variation for both mortality and hospital costs.

    Increased frequency of retractions has recently been observed, and retractions are important events that deserve scientific investigation. This study aimed to characterize cases of retraction within general and internal medicine in a high-profile database, with interest in the country of origin of the article and the impact factor (IF) of the journal in which the retraction was made. This study consisted of reviewing retraction notes in the Thomson-Reuters Web of Knowledge (WoK) indexing database, within general and internal medicine. The retractions were classified as plagiarism/duplication, error, fraud and authorship problems and then aggregated into two categories: "plagiarism/duplication" and "others." The countries of origin of the articles were dichotomized according to the median of the indicator "citations per paper" (CPP), and the IF was dichotomized according to its median within general and internal medicine, also obtained from the WoK database. These variables were analyzed using contingency tables according to CPP (high versus low), IF (high versus low) and period (1992-2002 versus 2003-2014). The relative risk (RR) and 95% confidence interval (CI) were estimated for plagiarism/duplication. A total of 86 retraction notes were identified, and retraction reasons were found for 80 of them. The probability that plagiarism/duplication was the reason for retraction was more than three times higher for the low CPP group (RR: 3.4; 95% CI: [1.9-6.2]), and similar results were seen for the IF analysis. The study identified greater incidence of plagiarism/duplication among retractions from countries with lower scientific impact.

    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.

    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.

    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.

  1. Simulations of the cardiac action potential based on the Hodgkin-Huxley kinetics with the use of Microsoft Excel spreadsheets.

    Wu, Sheng-Nan

    2004-03-31

    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.

    The potential for adverse events with lasting functional effects makes cranial nerve (CN) injury a target for litigation. Our objective was to comprehensively examine records of malpractice trials and detail issues influencing outcomes. Retrospective analysis. The Westlaw database (Thomson Reuters, New York, NY) was searched for jury verdict reports related to medical malpractice and CN injury. After excluding nonrelevant cases, we examined 209 trials for characteristics including nerve(s) injured, alleged causes of malpractice, demographic information, specialty, and outcome. The most commonly litigated CNs were VII (24.4%) and II (19.6%). Sixty-nine (33.0%) trials resulted in damages awarded. Outcomes varied, ranging from a 29.2% plaintiff success rate for CN XI injury to 48.4% for CN II injury. Plaintiffs had less success with increasing age. Average damages awarded were $1.7 million. The most commonly named defendants were otolaryngologists and general surgeons. Individual considerations varied but commonly included alleged deficits in informed consent (25.4%), unnecessary procedures (14.8%), undergoing additional surgery (25.8%), and untimely recognition of complications (23.9%). Malpractice trials were resolved in the defendant's favor the majority of the time. In cases where plaintiffs were successful, however, awards were considerable, averaging nearly $2 million. Factors influencing case outcome included age, location, perceived deficits in informed consent, allegedly unnecessary surgery, requiring additional surgery to repair a complication, and untimely recognition of complications. Although specific factors should be taken into consideration with each procedure, providing detailed informed consent and communicating with patients regarding expectations may minimize liability.

    To evaluate and compare the characteristics of court verdicts on medical errors allegedly harming patients in Spain and Massachusetts from 2002 to 2012. We reviewed 1041 closed court verdicts obtained from data on litigation in the Thomson Reuters Aranzadi Westlaw databases in Spain (Europe), and 370 closed court verdicts obtained from the Controlled Risk and Risk Management Foundation of Harvard Medical Institutions (CRICO/RMF) in Massachusetts (USA). We included closed court verdicts on medical errors. The definition of medical errors was based on that of the Institute of Medicine (USA). We excluded any agreements between parties before a judgement. Medical errors were involved in 25.9% of court verdicts in Spain and in 74% of those in Massachusetts. The most frequent cause of medical errors was a diagnosis-related problem (25.1%; 95% CI 20.7% to 31.1% in Spain; 35%; 95% CI 29.4% to 40.7% in Massachusetts). The proportion of medical errors classified as high severity was 34% higher in Spain than in Massachusetts (p=0.001). The most frequent factors contributing to medical errors in Spain were surgical and medical treatment (p=0.001). In Spain, 98.5% of medical errors resulted in compensation awards compared with only 6.9% in Massachusetts. This study reveals wide differences in litigation rates and the award of indemnity payments in Spain and Massachusetts; however, common features of both locations are the high rates of diagnosis-related problems and the long time interval until resolution.

    Medicolegal factors contribute to increasing healthcare costs through the direct costs of malpractice litigation, malpractice insurance premiums, and defensive medicine. Malpractice litigation trends are constantly changing as a result of technological innovations and changes in laws. In this study, we examine the most recent legal decisions related to Otolaryngology and characterize the factors responsible for determining legal responsibility. The Westlaw legal database (Thomson Reuters, New York, NY) was used to search for jury verdicts since 2008 in Otolaryngology malpractice cases. The 44 cases included in this analysis were studied to determine the procedures most commonly litigated and progressing to trial, as well as the year, location, alleged cause of malpractice, specialty of co-defendants, and case outcomes. Out of the 44 cases included in this analysis, physicians were not found liable in 36 (81.8%) cases. Rhinologic procedures comprised 38.6% of cases litigated, and rulings were in physicians' favor in 66.7% of endoscopic sinus surgery (ESS) cases and all non-ESS rhinologic cases. A perceived lack of informed consent was noted in 34.1% of cases. The 8 jury awards averaged $940,000 (range, $148,000-$3,600,000). Otolaryngologists were not found liable in the majority of cases reviewed. Rhinologic surgeries were the most common procedures resulting in litigation. Adenotonsillectomies, thyroidectomies, and airway management are also well-represented. Perceived deficits in informed consent and misdiagnosis were noted in a considerable proportion of otolaryngologic malpractice cases resulting in jury decisions. Copyright © 2013 Elsevier Inc.

    The potentially severe complications resulting from cerebrospinal fluid (CSF) leak makes iatrogenic injury a medicolegal area of concern for otolaryngologists and neurosurgeons. The objectives of this analysis were to study legal outcomes as well as medical and nonmedical elements affecting malpractice litigation. Public court records available in the Westlaw legal database (Thomson Reuters, New York, NY) were searched for medical malpractice litigation related to iatrogenic CSF leak. Of the 18 jury verdicts and settlements included, outcomes and awards, patient demographic data, and other factors instrumental in determining legal responsibility were recorded for comparison. Ten (55.6%) cases were resolved in the defendant's favor, 2 (11.1%) resulted in damages awarded by a jury, and 6 (33.3%) were settled out of court before resolution of trial. Mean damages awarded were $1.1 million, while out of court settlements averaged $966,887. Malpractice stemming from patients who underwent endoscopic sinus surgery comprised 77.8% of cases analyzed. The most frequent alleged factors cited for litigation included having to undergo additional surgery (88.9%), developing meningitis (50.0%), and failing to recognize complications in a timely manner (44.4%). Perceived deficits in informed consent were alleged in one-third of cases. Although a slight majority of cases were resolved in the defendant's favor, payments made were considerable, averaging approximately $1 million. Strategies to decrease liability and allow patients to make more informed decisions should include clear communication with patients that explicitly states potential risks, such as meningitis, and possible need to undergo additional reparative surgery. © 2013 ARS-AAOA, LLC.

    To assess characteristics associated with various outcomes of malpractice litigation, resulting from injuries sustained during oculoplastic procedures. The Westlaw legal database (Thomson Reuters, New York, NY, U.S.A.) was used to obtain jury verdicts and settlements. Pertinent data were extracted from 69 malpractice cases litigated from 1988 to 2012 involving oculoplastic procedures, including alleged cause of malpractice, outcome, and defendant specialty. The most commonly litigated surgical procedures were blepharoplasty (63.8% of total) and brow lift surgery (11.6%). The most commonly alleged complications included excessive scarring (24.6%), lagophthalmos (24.6%), visual defects (23.2%), and exposure keratitis (21.7%). Plastic surgeons were the most commonly named defendants (46.4%), followed by both comprehensive ophthalmologists and fellowship-trained ophthalmic plastic surgeons (17.3% each). A defense verdict was held in 60.9% of cases, a plaintiff verdict in 31.9% of cases, and a settlement was reached in 7.2% of cases. Blindness, cranial nerve injury, and the allegation of a permanent deficit increased the likelihood of a case being resolved with payment to the plaintiff (Fisher exact tests, p < 0.05). Most litigated oculoplastic malpractice cases were resolved in favor of the defendant, while settlements and plaintiff decisions averaged $455,703. Blepharoplasty constituted two-thirds of cases, with the most frequently cited associated complications being unsightly scarring, lagophthalmos, and visual deficits. An alleged lack of informed consent (30.4%) or the need for additional surgery (39.1%) was present in a considerable proportion of cases, emphasizing the importance of a detailed informed consent and clear communication preoperatively regarding patient expectations.

    Meningitis is a potential complication in otolaryngologic procedures and conditions. Severe sequelae make understanding factors involved in relevant malpractice litigation critical. We analyze pertinent litigation for awards, outcomes, patient demographic factors, and other alleged causes of malpractice. Pertinent jury verdict and settlement reports were examined using the Westlaw legal database (Thomson Reuters, New York, NY). Twenty-three cases (60.5%) involved non-iatrogenic injuries, including inadequate treatment or failure to diagnose sinusitis or otitis media, while 15 (39.5%) involved iatrogenic cases, mostly rhinologic procedures. 36.8% of cases were resolved for the defendant, 28.9% with juries awarding damages, and 34.2% with settlements. Although not statistically significant, mean damages awarded were higher than settlements ($2.1 vs. 1.5M, p=0.056), and cases involving pediatric patients were more likely to be resolved with payment than those with adult litigants (80.0% vs. 52.2%, p=0.08 respectively). Other frequent alleged factors included permanent deficits (63.2%), requiring additional surgery (41.1%), death (34.2%), cognitive deficits (21.2%), deafness (15.8%), and inadequate informed consent (33.0% of iatrogenic cases). Practitioners facing litigation related to meningitis may wish to consider these findings, notably for cases involving death or permanent functional deficits, as cases with out of court settlements tended to be resolved with lower payments. Cases involving misdiagnosis may be more likely to be resolved with payment compared with iatrogenic cases. By understanding the issues detailed in this analysis and including them in the informed consent process for patients undergoing rhinologic and otologic procedures, otolaryngologists may potentially improve patient safety and decrease liability. © 2014.

    Laryngotracheal stenosis usually occurs as a result of injury from endotracheal intubation or tracheostomy placement. With an estimated incidence of 1% to 22% after these procedures, chronic sequelae ranging from discomfort to devastating effects on quality of life, and even death, make this complication a potential litigation target. We examined federal and state court records for malpractice regarding laryngotracheal stenosis and examined characteristics influencing determination of liability. Retrospective analysis. The Westlaw Next legal database (Thomson Reuters, New York, NY) was searched for pertinent federal and state malpractice cases and examined for several factors including alleged cause of malpractice, complications, case outcome, and specialty of the defendants. Twenty-three pertinent cases over 35 years were identified. Fourteen (60.9%) cases were decided in the physician's favor, with six plaintiff verdicts awarding an average of $922,129 for malpractice, and three out-of-court settlements averaging $441,600. Hospitals were the most frequently named defendants, and anesthesiologists were most commonly named physician defendants. Endotracheal intubations and tracheostomy history were frequent factors in these cases. Laryngeal lesions were more likely to result in payments, trending higher than those stemming from tracheal lesions. Multiple cases mentioned previous intubation as a potential risk factor that may have led to laryngotracheal stenosis. Location of stenosis and requirement of reparative procedures may also influence outcomes. Cases not decided in the defendant's favor frequently included other extenuating circumstances, including severity of other injuries. Although the majority of cases were defendant decisions, the verdicts decided for the plaintiffs had considerable damages awarded.

    This paper describes verdicts in court involving injury-producing medical errors in Spain. A descriptive analysis of 1041 closed court verdicts from Spain between January 2002 and December 2012. It was determined whether a medical error had occurred, and among those with medical error (n = 270), characteristics and results of litigation were analyzed. Data on litigation were obtained from the Thomson Reuters Aranzadi Westlaw databases. All verdicts involving health system were reviewed and classified according to the presence of medical error. Among those, contributory factors, medical specialty involved, health impact (death, disability and severity) and results of litigation (resolution, time to verdict and economic compensations) were described. Medical errors were involved in 25.9% of court verdicts. The cause of medical error was a diagnosis-related problem in 25.1% and surgical treatment in 22.2%, and Obstetrics-Gynecology was the most frequent involved specialty (21%). Most of them were of high severity (59.4%), one-third (32%) caused death. The average time interval between the occurrence of the error and the verdict was 7.8 years. The average indemnity payment was €239 505.24; the highest was psychiatry (€7 585 075.86) and the lowest was Emergency Medicine (€69 871.19). This study indicates that in Spain medical errors are common among verdicts involving the health system, most of them causing high-severity adverse outcomes. The interval between the medical error and the verdict is excessive, and there is a wide range of economic compensation. © The Author 2015.

    In this study, we detailed factors governing legal outcomes in iatrogenic orbital injury, with the purpose of discussing strategies to minimize liability and enhance patient safety. Retrospective analysis. Jury verdict and settlement reports were searched from publically available federal and state court records using the Westlaw database (Thomson Reuters, New York, NY). After exclusion of nonrelevant cases, 20 cases of iatrogenic orbital injuries were examined for factors such as legal outcome, damages awarded, defendant specialty, alleged causes of malpractice, and patient demographic information. The majority (60.0%) of cases were resolved in the defendant's favor. Payment was considerable for the cases decided in support of the plaintiff, averaging $1.13 million. Out-of-court settlements averaged $1.78 million (range, $487,500-$3.9 million), whereas jury-awarded damages averaged $472,661 (range, $75,000-$763,214). Complications stemming from endoscopic sinus surgery were most common (50.0%). Diplopia was the most common medical complaint (50.0%), whereas permanent deficits and having to undergo additional surgery were each present in 65.0% of cases. The potential for permanent sequelae of iatrogenic orbital injury makes this complication susceptible to malpractice litigation. Otolaryngologists were the most common defendants. Although cases were resolved in the defendant's favor 60% of the time, payments made were considerable, averaging $1.13 million. Steps to minimize liability and improve patient safety include an informed consent process explicitly listing risks, including diplopia and blindness, and obtaining timely ophthalmology consultation when a complication is recognized.

    Objectives To evaluate and compare the characteristics of court verdicts on medical errors allegedly harming patients in Spain and Massachusetts from 2002 to 2012. Design, setting and participants We reviewed 1041 closed court verdicts obtained from data on litigation in the Thomson Reuters Aranzadi Westlaw databases in Spain (Europe), and 370 closed court verdicts obtained from the Controlled Risk and Risk Management Foundation of Harvard Medical Institutions (CRICO/RMF) in Massachusetts (USA). We included closed court verdicts on medical errors. The definition of medical errors was based on that of the Institute of Medicine (USA). We excluded any agreements between parties before a judgement. Results Medical errors were involved in 25.9% of court verdicts in Spain and in 74% of those in Massachusetts. The most frequent cause of medical errors was a diagnosis-related problem (25.1%; 95% CI 20.7% to 31.1% in Spain; 35%; 95% CI 29.4% to 40.7% in Massachusetts). The proportion of medical errors classified as high severity was 34% higher in Spain than in Massachusetts (p=0.001). The most frequent factors contributing to medical errors in Spain were surgical and medical treatment (p=0.001). In Spain, 98.5% of medical errors resulted in compensation awards compared with only 6.9% in Massachusetts. Conclusions This study reveals wide differences in litigation rates and the award of indemnity payments in Spain and Massachusetts; however, common features of both locations are the high rates of diagnosis-related problems and the long time interval until resolution.

    With nearly 50 years' of development, Injury has become one of the leading journals in its specialty. The aim of this article is to identify, analyze the characteristics of the 100 most cited articles published by the journal to date. We searched the Thomson Reuters Web of Science Core Collection for citations of all articles published in Injury since its launch. For the Top 100 most frequently cited articles, title, author name, number of authors, publishing date, citation number, country of origin, institution, pages, number of reference, type of article, study topic, study design, funding source, and level of evidence of each clinical article were recorded and analyzed. Only 50 self-citations were found in 12436 total citations of the top100 articles, fifty-four articles exceeded 100 citations. Total citations of the Top 100 articles ranged from 77 to 599. The Top 100 articles were published between 1973 and 2012, the mean authorship and institution number per paper was 3.92 and 1.84 respectively. The mean page number was 8.26 and the mean reference number was 45.2. England, Germany and Switzerland ranked the top three countries of origin. Among the T100 articles, there were 50 clinical studies, 5 basic researches, and 45 reviews. The most common study type was case series, and most common topics were bone reconstruction, trauma and bone fracture. The most common level of evidence was level Ⅳ. This study may help researchers to find out the important information on the classic articles and provides useful insights for the authors who want to publish their research in Injury.

    Objectives To determine in a large claims database the healthcare utilization and costs associated with treatment of alcohol dependence with medications vs no medication and across 4 US Food and Drug Administration (FDA)–approved medications. Study Design Claims database analysis. Methods Eligible adults with alcohol dependence claims (n = 27,135) were identified in a commercial database (MarketScan; Thomson Reuters Inc, Chicago, Illinois). Following propensity score–based matching and inverse probability weighting on demographic, clinical, and healthcare utilization variables, patients who had used an FDA-approved medication for alcohol dependence (n = 2977) were compared with patients who had not (n = 2977). Patients treated with oral naltrexone hydrochloride (n = 2064), oral disulfiram (n = 2076), oral acamprosate calcium (n = 5068), or extended-release injectable naltrexone (naltrexone XR) (n = 295) were also compared for 6-month utilization rates of alcoholism medication, inpatient detoxification days, alcoholism-related inpatient days, and outpatient services, as well as inpatient charges. Results Patients who received alcoholism medications had fewer inpatient detoxification days (706 vs 1163 days per 1000 patients, P alcoholism-related inpatient days (650 vs 1086 days, P alcoholism-related emergency department visits (127 vs 171, P = .005). Among 4 medications, the use of naltrexone XR was associated with fewer inpatient detoxification days (224 days per 1000 patients) than the use of oral naltrexone (552 days, P = .001), disulfiram (403 days, P = .049), or acamprosate (525 days, P alcoholism-related inpatient days than the groups receiving disulfiram or acamprosate. More patients in the naltrexone XR group had an outpatient substance abuse visit compared with patients in the oral alcoholism medication groups. Conclusion Patients who received an alcoholism medication had lower healthcare utilization than patients who did not. Naltrexone XR showed an

    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 Objective: 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. Methods: 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. Results: 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. Conclusions: 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.

    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

    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.

    Bibliometric analysis. To apply the established technique of citation analysis to identify the 100 most influential articles in scoliosis surgery research published between 1900 and 2015. Previous studies have applied the technique of citation analysis to other areas of study. This is the first article to apply this technique to the field of scoliosis surgery. A two-step search of the Thomson Reuters Web of Science was conducted to identify all articles relevant to the field of scoliosis surgery. The top 100 articles with the most citations were identified based on analysis of titles and abstracts. Further statistical analysis was conducted to determine whether measures of author reputation and overall publication influence affected the rate at which publications were recognized and incorporated by other researchers in the field. Total citations for the final 100 publications included in the list ranged from 82 to 509. The period for publication ranged from 1954 to 2010. Most studies were published in the journal Spine (n = 63). The most frequently published topics of study were surgical techniques (n = 35) and outcomes (n = 35). Measures of author reputation (number of total studies in the top 100, number of first-author studies in the top 100) were found to have no effect on the rate at which studies were adopted by other researchers (number of years until first citation, and number of years until maximum citations). The number of citations/year a publication received was found to be negatively correlated with the rate at which it was adopted by other researchers, indicating that more influential manuscripts attained more rapid recognition by the scientific community at large. In assembling this publication, we have strived to identify and recognize the 100 most influential articles in scoliosis surgery research from 1900 to 2015. N/A.

    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.

    The South American tomato pinworm, Tuta absoluta (Meyrick) has been introduced into new geographic areas, including the Mediterranean region, where it has become a serious threat to tomato production. Three greenhouse trials conducted in tomato crops during 2009 and 2010 explored control strategies using the egg-parasitoid Trichogramma achaeae Nagaraja and Nagarkatti compared with chemical control. The effectiveness of the predator Nesidiocoris tenuis (Reuter) was also tested. In greenhouses with early pest infestations (discrete generations), periodic inundative releases (eight releases at a rate of 50 adults/m2, twice a week) were necessary to achieve an adequate parasitism level (85.63 +/- 5.70%) early in the growing season. However, only one inoculative release (100 adults/m2) was sufficient to achieve a comparatively high parasitism level (91.03 +/- 12.58%) under conditions of high pest incidence and overlapping generations. Some intraguild competition was observed between T. achaeae and the predator, N. tenuis. This mirid species is commonly used in Mediterranean greenhouse tomato crops for the control of the sweetpotato whitefly, Bemisia tabaci (Gennadius). Tomato cultivars were also observed to influence the activity of natural enemies, mainly N. tenuis (whose average numbers ranged between 0.17 +/- 0.03 and 0.41 +/- 0.05 nymphs per leaf depending on the cultivar). This may be because of differences in plant nutrients in different cultivars, which may affect the feeding of omnivorous insects. In contrast, cultivar effects on T. achaeae were less apparent or possibly nonexistent. Nevertheless, there was an indirect effect in as much as T. achaeae was favored in cultivars not liked by N. tenuis.

    Full Text Available With the present issue, Studies in Second Language Learning and Teaching enters the fifth year of its existence, a year that has already started on a very positive note as the journal has just been included in the European Reference Index for the Humanities (ERIH PLUS. This, as well as the fact that SSLLT has been indexed or abstracted in other prestigious databases, constitutes tangible proof of the growing recognition that it has been gaining in the field. It is also likely to contribute to a considerable increase in the number of citations, something that we need really badly if we want to have the journal listed by the Thomson Reuters Master Journal List. This is certainly a goal that we will be vigorously pursuing and I am confident that we will be able to accomplish it in the near future. Obviously, the number of citations depends in the main on the quality of the papers published because only the best ones stand the chance of being referred to by other specialists, particularly those who routinely publish their work in the most prestigious journals in the field. We are doing our best to ensure the highest possible quality of the papers that appear in SSLLT and one way to do it is to invite renowned scholars as guest editors of thematic issues. This is exactly what is going to happen this year since Sarah Mercer and Stephen Ryan have kindly agreed to put together two issues of the journal which will include papers based on presentations delivered during the first conference on psychology and language learning, which was held in Graz in May, 2014. The line-up of contributors to these two issues is really impressive and they will surely be a real treat for our readers. This is by no means to suggest that the papers included in the regular editions are any less valuable or engaging, as amply demonstrated by the present one.

    Mesembrine alkaloids are considered to be the primary active constituents of the South African medicinal plant Sceletium tortuosum (L.) N.E.Br. (Aizoaceae), and it is used as the dried or fermented aerial material from the plant, which is known as kanna (aka, channa, kougoed). Traditional regional use ranged from relieving thirst, mild analgesia, and alteration of mood. Current interest has focused primarily on the antidepressant action of preparations based on the plant and commercialization is expanding the recognition and availability of these preparations. Searches for the keywords "Sceletium or mesembrine" were performed in "PubMed-NCBI", "Chemical Abstracts SciFinder" and "Thomson Reuters Web of Science" databases in addition to the inclusion of references cited within prior reviews and scientific reports. Additionally the "SciFinder" database was searched using 3a-phenyl-cis-octahydroindole in the SciFinder Substructure Module (SSM). Plant taxonomy was validated by the database "The Plant List". This review focuses on the chemistry, analysis, and pharmacology of the mesembrine alkaloids. Despite a long history of medicinal used and research investigation, there has been a renewed interest in the pharmacological properties of the mesembrine alkaloids and much of the pharmacology has only recently been published. The two major active alkaloids mesembrine and mesembrenone are still in the process of being more fully characterized pharmacologically. They are serotonin reuptake inhibitors, which provides a rationale for the plant's traditional use as an antidepressant, but other actions are beginning to appear in the literature. Additionally, mesembrenone has reasonably potent PDE4 inhibitory activity. This review intends to provide an overview of the available literature, summarize the current findings, and put them in perspective with earlier studies and reviews.

    Currently one of the main goals of editors is to attain a higher visibility for their journals. On the other hand, authors strive to publish their research in journals indexed in eminent databases such as Scopus, Thompson Reuters' Web of Science (ISI), Medline, etc. Therefore, clarifying the standards of indexing is of great importance. One of the most important issues in publication is the ethical considerations, which are mainly described by organizations, such as the International Committee of Medical Journal Editors and the Committee on Publication Ethics. In this study, we examined the ethical requirements of high impact databases for indexing journals to investigate whether they mention or mandate journals to adhere to publication ethics. We found that only Scopus mandated journals to state clear ethical policies on their website as a criterion for being indexed while Medline and Directory of Open Access Journals advised journals to adhere to ethics, not mandated, and Web of Science (ISI) and PubMed Central made no mention of ethics as a required criterion for indexing. Based on this short review, there seems to be a gap between the requirements of indexing systems and international guidelines for publication ethics. Currently, most indexing systems have only partially recommended journals to consider ethical issues. In such an atmosphere, we cannot expect journals or as a result, authors to professionally, completely, and whole heartedly implement ethical guidelines as a mandatory rule in their journals and research, when the indexing systems that most editors want to be indexed in and most authors want to be cited in do not mandate such guidelines.

    Graph regularized nonnegative matrix factorization (GNMF) decomposes a nonnegative data matrix X[Symbol:see text]R(m x n) to the product of two lower-rank nonnegative factor matrices, i.e.,W[Symbol:see text]R(m x r) and H[Symbol:see text]R(r x n) (r gradient direction with a non-optimal step size. Recently, a multiple step-sizes fast gradient descent (MFGD) method has been proposed for optimizing NMF which accelerates MUR by searching the optimal step-size along the rescaled negative gradient direction with Newton's method. However, the computational cost of MFGD is high because 1) the high-dimensional Hessian matrix is dense and costs too much memory; and 2) the Hessian inverse operator and its multiplication with gradient cost too much time. To overcome these deficiencies of MFGD, we propose an efficient limited-memory FGD (L-FGD) method for optimizing GNMF. In particular, we apply the limited-memory BFGS (L-BFGS) method to directly approximate the multiplication of the inverse Hessian and the gradient for searching the optimal step size in MFGD. The preliminary results on real-world datasets show that L-FGD is more efficient than both MFGD and MUR. To evaluate the effectiveness of L-FGD, we validate its clustering performance for optimizing KL-divergence based GNMF on two popular face image datasets including ORL and PIE and two text corpora including Reuters and TDT2. The experimental results confirm the effectiveness of L-FGD by comparing it with the representative GNMF solvers.

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. Keywords: physical activity, controlled trial, relaxation, inpatient treatment

    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.

    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.

    Fentanyl is a potent synthetic opioid with large abuse potential. A common preparation of fentanyl is a sustained-release transdermal patch. To our knowledge, there are only two published case reports of whole patch ingestion. A case series of 76 patients with a history of whole patch ingestion is reported. To characterize whole fentanyl patch ingestion to develop a clinical guideline for management. This was a retrospective review of all patients who ingested intact fentanyl patches as reported to three regional poison information centers (RPIC) from 2000 to 2008. The three RPIC medical record databases were queried for all exposures with a substance code matching the Micromedex® (Thomson Reuters, New York, NY) fentanyl product codes. Collected data included: age, gender, reason for the exposure, number of patches ingested, dose (μg/h), symptoms, symptom onset and duration, treatment hospital flow (level of care), and outcome. A total of 76 patients met the inclusion criteria. Two patients had both time of onset and symptom duration documented. In both patients, the signs and symptoms developed within 2 h of the exposure, and the patients were asymptomatic at 6½ and 9 h, respectively. Fifty-eight (78.3%) patients were admitted. Of those patients who were admitted, 56 (96.5%) were admitted to a critical care unit. Fourteen patients required intubation, and naloxone infusions were documented in eight cases. Ingestion of whole fentanyl patches may lead to prolonged and significant toxicity based on these poison center data. Copyright © 2012 Elsevier Inc. All rights reserved.

    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.

    Preclinical studies have demonstrated that β-adrenergic receptor antagonists could improve the prognosis of breast cancer. However, the conclusions of clinical and pharmacoepidemiological studies have been inconsistent. This review was conducted to re-assess the relationship between beta-adrenoceptor blockers and breast cancer prognosis. The literature was searched from PubMed, EMBASE and Web of Nature (Thompson Reuters) databases through using key terms, such as breast cancer and beta- adrenoceptor blockers. Ten publications met the inclusion criteria. Six suggested that receiving beta- adrenoceptor blockers reduced the risk of breast cancer-specific mortality, and three of them had statistical significance (hazard ratio (HR)=0.42; 95% CI=0.18-0.97; p=0.042). Two studies reported that risk of recurrence and distant metastasis (DM) were both significantly reduced. One study demonstrated that the risk of relapse- free survival (RFS) was raised significantly with beta-blockers (BBS) (HR= 0.30; 95% CI=0.10-0.87; p=0.027). One reported longer disease-free interval (Log Rank (LR)=6.658; p=0.011) in BBS users, but there was no significant association between overall survival (OS) and BBS (HR= 0.35; 95% CI=0.12-1.0; p=0.05) in five studies. Through careful consideration, it is suggested that beta-adrenoceptor blockers use may be associated with improved prognosis in breast cancer patients. Nevertheless, larger size studies are needed to further explore the relationship between beta-blocker drug use and breast cancer prognosis.

    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.

    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.

    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.

    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.

    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 %).

    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

    2014-01-01

    This paper explores the changing role of world regions (North America, EU15, South EU, Central and Eastern Europe (CEE), Former-USSR, Latin America, Asia Pacific and the Middle East) in science from 1981 to 2011. We use bibliometric data extracted from Thomson Reuter's National Science Indicators (2011) for 21 broad disciplines, and aggregated the data into the four major science areas: life, fundamental, applied and social sciences. Comparing three sub-periods (1981-1989, 1990-2000 and 2001-2011), we investigate (i) over time changes in descriptive indicators such as publications, citations, and relative impact; (ii) static specialization measured by revealed comparative advantage (RCA) in citations and papers; and (iii) dynamic specialization measured by absolute growth in papers. Descriptive results show a global shift in science largely in quantity (papers) and much less in impact (citations). We argue this should be interpreted as a shift in science's absorptive capacity but not necessarily a shift of knowledge generation at the world science frontier, which reflects the nature of science systems operating with high inertia and path dependency in areas of their historically inherited advantages and disadvantages. In view of their common historical legacy in science we are particularly interested in the process of convergence/divergence of the catching-up/transition regions with the world frontier regions. We implement an interpretative framework to compare regions in terms of their static and dynamic specialization from 1981-1989 to 2001-2011. Again, our analysis shows that while science systems are mostly characterised by strong inertia and historically inherited (dis)advantages, Asia Pacific, Latin America and CEE show strong catching-up characteristics but largely in the absorptive capacity of science.

    The abundance of macro-level studies on scientific production in the field of biomedicine in Spain only serves to highlight the scarcity of micro-level studies reporting on the activity of research groups-the basic units of the science and technology system. This lack of information may well be explained by the ambiguity inherent in the "research group" concept and by the existence of synonymous and homonymous bibliographic signatures that confuse the correspondence between these and the real authors. The aim of this study is to describe bibliographic production in cardio-cerebrovascular research and identify research groups active in the field. Using Thomson-Reuters' National Citation Report for Spain database and the National Library of Medicine Medical Subject Headings thesaurus, we defined the field of cardio-cerebrovascular research and identified research groups through co-authorship analysis supported by the opinions of an expert. Groups were described in terms of bibliometric indicators of activity and visibility. Ninety-three groups made up of 772 different authors were identified from an initial subset of 6540 publications on cardio-cerebrovascular research. The groups we identified came mainly from the healthcare sector and the universities and were mostly located in the autonomous regions of Catalonia and the Community of Madrid. The scientific production attributable to the groups presented indicators of visibility above the mean for biomedicine. Collaboration between the healthcare sector and the universities dominated cardio-cerebrovascular research, although international collaboration rates were poor, standing at levels below the mean for biomedicine.

    Our recent work has shown that older adults are disproportionately impaired at bimanual tasks when the two hands are moving out of phase with each other [Bangert, A. S., Reuter-Lorenz, P. A., Walsh, C. M., Schachter, A. B., & Seidler, R. D. Bimanual coordination and aging: Neurobehavioral implications. Neuropsychologia, 48, 1165–1170, 2010]. Interhemispheric interactions play a key role during such bimanual movements to prevent interference from the opposite hemisphere. Declines in corpus callosum (CC) size and microstructure with advancing age have been well documented, but their contributions to age deficits in bimanual function have not been identified. In the current study, we used structural magnetic resonance and diffusion tensor imaging to investigate age-related changes in the relationships between callosal macrostructure, microstructure, and motor performance on tapping tasks requiring differing degrees of interhemispheric interaction. We found that older adults demonstrated disproportionately poorer performance on out-of-phase bimanual control, replicating our previous results. In addition, older adults had smaller anterior CC size and poorer white matter integrity in the callosal midbody than their younger counterparts. Surprisingly, larger CC size and better integrity of callosal microstructure in regions connecting sensorimotor cortices were associated with poorer motor performance on tasks requiring high levels of interhemispheric interaction in young adults. Conversely, in older adults, better performance on these tasks was associated with larger size and better CC microstructure integrity within the same callosal regions. These findings implicate age-related declines in callosal size and integrity as a key contributor to bimanual control deficits. Further, the differential age-related involvement of transcallosal pathways reported here raises new questions about the role of the CC in bimanual control. PMID:20954936

    Analysis of the number of citations within a given specialty provides information on the classic publications of that specialty. The goals of this study were to identify the 50 most cited articles on rotator cuff repair and to analyze various characteristics of these articles. The ISI Web of Science (Thomson Reuters, Philadelphia, Pennsylvania) was used to conduct a search for the term rotator cuff repair. The 50 most cited articles were retrieved, and the following objective characteristics of each article were recorded: number of times cited, citation density, journal, country of origin, and language. The following subjective characteristics of each article were also recorded: article type (clinical vs basic science), article subtype, and level of evidence for clinical articles. Of the 50 most cited articles on rotator cuff repair, the number of citations ranged from 138 to 677 (mean, 232±133 citations) and citation density ranged from 3.8 to 53.5 citations per year (mean, 16.9±9.2 citations per year). The articles were published between 1974 and 2011, with most of the articles published in the 2000s (29 articles), followed by the 1990s (16 articles). The articles originated from 8 countries, with the United States accounting for 30 articles (60%). Overall, 66% of the articles were clinical and 34% were basic science. The most common article subtype was the clinical case series (48%). Of the 33 clinical articles, 24 (73%) were level IV. Among the 50 most cited articles on rotator cuff repair, the case series was the most common article subtype, showing the effect that publication of preliminary outcomes and new surgical techniques has had on surgeons performing rotator cuff repair.

    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.

  3. The rate of growth in scientific publication and the decline in coverage provided by Science Citation Index.

    2010-09-01

    The growth rate of scientific publication has been studied from 1907 to 2007 using available data from a number of literature databases, including Science Citation Index (SCI) and Social Sciences Citation Index (SSCI). Traditional scientific publishing, that is publication in peer-reviewed journals, is still increasing although there are big differences between fields. There are no indications that the growth rate has decreased in the last 50 years. At the same time publication using new channels, for example conference proceedings, open archives and home pages, is growing fast. The growth rate for SCI up to 2007 is smaller than for comparable databases. This means that SCI was covering a decreasing part of the traditional scientific literature. There are also clear indications that the coverage by SCI is especially low in some of the scientific areas with the highest growth rate, including computer science and engineering sciences. The role of conference proceedings, open access archives and publications published on the net is increasing, especially in scientific fields with high growth rates, but this has only partially been reflected in the databases. The new publication channels challenge the use of the big databases in measurements of scientific productivity or output and of the growth rate of science. Because of the declining coverage and this challenge it is problematic that SCI has been used and is used as the dominant source for science indicators based on publication and citation numbers. The limited data available for social sciences show that the growth rate in SSCI was remarkably low and indicate that the coverage by SSCI was declining over time. National Science Indicators from Thomson Reuters is based solely on SCI, SSCI and Arts and Humanities Citation Index (AHCI). Therefore the declining coverage of the citation databases problematizes the use of this source.

    The significant medical and economic tolls of spinal disorders, increasing volume of spine surgeries, and focus on quality metrics have made it imperative to understand postoperative complications. This study demonstrates the utility of a longitudinal administrative database for capturing overall and procedure-specific complication rates after various spine surgery procedures. The Thomson Reuters MarketScan Commercial Claims and Encounters and the Medicare Supplemental and Coordination of Benefits database was used to conduct a retrospective analysis of longitudinal administrative data from a sample of approximately 189,000 patients. Overall and procedure-specific complication rates at 5 time points ranging from immediately postoperatively (index) to 30 days postoperatively were computed. The results indicated that the frequency of individual complication types increased at different rates. The overall complication rate including all spine surgeries was 13.6% at the index time point and increased to 22.8% at 30 days postoperatively. The frequencies of wound dehiscence, infection, and other wound complications exhibited large increases between 10 and 20 days postoperatively, while complication rates for new chronic pain, delirium, and dysrhythmia increased more gradually over the 30-day period studied. When specific surgical procedures were considered, 30-day complication rates ranged from 8.6% in single-level anterior cervical fusions to 27.3% in multilevel combined anterior and posterior lumbar spine fusions. This study demonstrates the usefulness of a longitudinal administrative database in assessing postoperative complication rates after spine surgery. Use of this database gave results that were comparable to those in prospective studies and superior to those obtained with nonlongitudinal administrative databases. Longitudinal administrative data may improve the understanding of overall and procedure-specific complication rates after spine surgery.

    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.

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.

    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.

    Bibliometrics and scientometrics are novel closely related scientific fields measuring and analyzing scientific publications in a certain area. Although spirituality, religion and health (S/R&H) field has been a growing study area in recent years, only a few bibliometric studies have been conducted on published literature in S/R&H. In this study, we aimed to perform bibliometric and scientometric analysis of the documents published in the Journal of Religion and Health, which is one of the most significant and productive journals in spirituality, religion and health field, during the period of 1975 to 2016. We used Thomson Reuters Web of Science database for the publication analyses. A total of 2683 papers were found and most of them were original articles (1655, 62.1%) followed by book reviews (780, 29.3%) and editorial materials (169, 6.3%). We found that the USA was the most productive country with 1665 papers and 62.45% of total literature followed by Australia and Canada. Cornell University in the USA was found to publish the highest number of documents with 73 papers and to cover 2.74% of the total literature followed by Duke University and Weill Cornell Medical College. A total of 2973 keywords were detected to be used. Most used five keywords were "religion," "spirituality," "religiosity," "health" and "mental health" (n = 253, 250, 97, 71 and 41 times, respectively). Our bibliometric and scientometric study of one of the most important leading journals in S/R&H area may encourage researchers to carry out further studies in this field.

    An examination of top-cited articles is a tool that can be used to identify and monitor outstanding scientific research. The goal of this study was to identify and analyze the characteristics of the 100 top-cited articles published in international journals dedicated to psychiatry. The Science Citation Index Expanded provided by the Thomson Reuters Institute for Scientific Information Web of Knowledge was searched in December, 2011, and 128 journals were identified in the subject category "Psychiatry." Each journal was searched on the Web of Science under "Publication Name" and the results were sorted by category "Times Cited." The 100 top-cited articles were recorded, and the list was analyzed with regard to journals, number of citations, authors, year, institution, and country of origin. The original research articles of the 100 top-cited articles were classified into one of five categories: scale/measurement, descriptive/epidemiology, mechanism, management, and imaging. The 100 top-cited articles were cited between 26,578 and 781 times; they were published between 1957 and 2005, with the largest number (35) published in the 1990s. The articles appeared in 24 journals, with more than half published in the Archives of General Psychiatry (56), followed by the American Journal of Psychiatry (6), and Psychological Medicine (6). Articles that dealt with the development, application, or validity of measurements led the list of top-cited psychiatric publications (43) and had a significantly higher number of citations compared with the rest of the articles. The time and language of publication, field of study, country of origin, and journal in which the paper appeared are possible determinants of the likelihood of citation and impact.

    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 impact factors of biomedical journals tend to rise over time. We sought to assess the trend in the impact factor, during the past decade, of journals published on behalf of United States (US) and European scientific societies, in four select biomedical subject categories (Biology, Cell Biology, Critical Care Medicine, and Infectious Diseases). We identified all journals included in the above-mentioned subject categories of Thomson Reuters Journal Citation Reports® for the years 1999, 2002, 2005, and 2008. We selected those that were published on behalf of US or European scientific societies, as documented in journal websites. We included 167 journals (35 in the subject category of Biology, 79 in Cell Biology, 27 in Critical Care Medicine, and 26 in Infectious Diseases). Between 1999 and 2008, the percentage increase in the impact factor of the European journals was higher than for the US journals (73.7±110.0% compared with 39.7±70.0%, p = 0.049). Regarding specific subject categories, the percentage change in the factor of the European journals tended to be higher than the respective US journals for Cell Biology (61.7% versus 16.3%), Critical Care Medicine (212.4% versus 65.4%), Infectious Diseases (88.3% versus 48.7%), whereas the opposite was observed for journals in Biology (41.0% versus 62.5%). Journals published on behalf of European scientific societies, in select biomedical fields, may tend to close the "gap" in impact factor compared with those of US societies. WHAT'S ALREADY KNOWN ABOUT THIS TOPIC?: The impact factors of biomedical journals tend to rise through years. The leading positions in productivity in biomedical research are held by developed countries, including those from North America and Western Europe. WHAT DOES THIS ARTICLE ADD?: The journals from European biomedical scientific societies tended, over the past decade, to increase their impact factor more than the respective US journals.

    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 impact factor summary statistics and growth trends among 31 medical and surgical specialties. © 2012 by the Society for Academic Emergency Medicine.

    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.

    The ATHENA trial (A placebo-controlled, double-blind, parallel arm Trial to assess the efficacy of dronedarone 400 mg bid for the prevention of cardiovascular Hospitalization or death from any cause in patiENts with Atrial fibrillation/atrial flutter) demonstrated that dronedarone reduced the risk of cardiovascular (CV) hospitalization/death by 24% (P or = 70 years with AF/AFL and > or = 1 stroke risk factor, without heart failure) who were hospitalized between January 2, 2005, and January 1, 2007, were identified from the MarketScan databases from Thomson Reuters. Health care costs were evaluated during the 12 months following the index hospitalization. The analysis included 10 200 ATHENA-like patients. Hospitalization for CV causes occurred in 53.9% of patients, with a total of 6700 CV hospitalizations for fatal/nonfatal causes. The most common nonfatal causes of CV hospitalizations were AF/other supraventricular rhythm disorders (20.2% of all CV hospitalizations), congestive heart failure (CHF; 14.3%), and transient ischemic attack (TIA)/stroke (10.7%). Mean costs per CV hospitalization for nonfatal causes were $10,908. Inpatient deaths from CV causes occurred in 264 (2.6%) patients; the most common causes of CV inpatient death were intracranial/gastrointestinal hemorrhage (24.2% of CV deaths), TIA/stroke (17.0%), and CHF (15.9%). Mean hospitalization costs per CV inpatient death were $18,565. Health care costs associated with CV hospitalizations and inpatient deaths among ATHENA-like patients in the US are high. Novel antiarrhythmic therapies such as dronedarone, with the potential to reduce CV hospitalizations/mortality in similar patients, could decrease health care costs if adopted in clinical practice.

    2017-01-01

    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

    Accurate staging of oesophageal cancer (OC) is vital. Bibliometric analysis highlights key topics and publications that have shaped understanding of a subject. The 100 most cited articles investigating radiological staging of OC are identified. The Thomas Reuters Web of Science database with search terms including "CT, PET, EUS, oesophageal and gastro-oesophageal junction cancer" was used to identify all English language, full-script articles. The 100 most cited articles were further analysed by topic, journal, author, year and institution. A total of 5,500 eligible papers were returned. The most cited paper was Flamen et al. (n = 306), investigating the utility of positron emission tomography (PET) for the staging of patients with potentially operable OC. The most common research topic was accuracy of staging investigations (n = 63). The article with the highest citation rate (38.00), defined as the number of citations divided by the number of complete years published, was Tixier et al. investigating PET texture analysis to predict treatment response to neo-adjuvant chemo-radiotherapy, cited 114 times since publication in 2011. This bibliometric analysis has identified key publications regarded as important in radiological OC staging. Articles with the highest citation rates all investigated PET imaging, suggesting this modality could be the focus of future research. • This study identifies key articles that investigate radiological staging of oesophageal cancer. • The most common topic was accuracy of staging investigations. • The article with the highest citation rate investigated the use of texture analysis in PET images.

    The number of citations a scientific article receives provides a good indication of its impact within any given field. This bibliometric analysis aimed to identify the 100 most cited articles in Emergency Abdominal Surgery (EAS), to highlight key areas of interest and identify those that have most significantly shaped contemporary clinical practice in this newly evolving surgical specialty. This is of increasing relevance as concerns grow regarding the variable and suboptimal outcomes in Emergency General Surgery. The Thomson Reuters Web of Science database was used to search using the terms [Emergency AND Abdom* AND Surg*] to identify all English language, full manuscripts. Results were ranked according to citation number. The top 100 articles were further analysed by subject, author, journal, year of publication, institution, and country of origin. The median (range) citation number of the top 100 out of 7433 eligible papers was 131 (1569-97). The most cited paper (by Goldman et al., Massachusetts General Hospital, New England Journal of Medicine; 1569 citations) focused on cardiac risk stratification in non-cardiac surgery. The Journal of Trauma, Injury, Infection and Critical Care published the most papers and received most citations (n = 19; 2954 citations. The majority of papers were published by centres in the USA (n = 52; 9422 citations), followed by the UK (n = 13; 1816 citations). The most common topics of publication concerned abdominal aneurysm management (n = 26) and emergency gastrointestinal surgery (n = 26). Vascular surgery, risk assessment and gastrointestinal surgery were the areas of focus for 59% of the contemporary most cited emergency abdominal surgery manuscripts. By providing the most influential references this work serves as a guide to what makes a citable emergency surgery paper. Crown Copyright © 2016. Published by Elsevier Ltd. All rights reserved.

    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.

    Graph regularized nonnegative matrix factorization (GNMF) decomposes a nonnegative data matrix to the product of two lower-rank nonnegative factor matrices, i.e., and () and aims to preserve the local geometric structure of the dataset by minimizing squared Euclidean distance or Kullback-Leibler (KL) divergence between X and WH. The multiplicative update rule (MUR) is usually applied to optimize GNMF, but it suffers from the drawback of slow-convergence because it intrinsically advances one step along the rescaled negative gradient direction with a non-optimal step size. Recently, a multiple step-sizes fast gradient descent (MFGD) method has been proposed for optimizing NMF which accelerates MUR by searching the optimal step-size along the rescaled negative gradient direction with Newton's method. However, the computational cost of MFGD is high because 1) the high-dimensional Hessian matrix is dense and costs too much memory; and 2) the Hessian inverse operator and its multiplication with gradient cost too much time. To overcome these deficiencies of MFGD, we propose an efficient limited-memory FGD (L-FGD) method for optimizing GNMF. In particular, we apply the limited-memory BFGS (L-BFGS) method to directly approximate the multiplication of the inverse Hessian and the gradient for searching the optimal step size in MFGD. The preliminary results on real-world datasets show that L-FGD is more efficient than both MFGD and MUR. To evaluate the effectiveness of L-FGD, we validate its clustering performance for optimizing KL-divergence based GNMF on two popular face image datasets including ORL and PIE and two text corpora including Reuters and TDT2. The experimental results confirm the effectiveness of L-FGD by comparing it with the representative GNMF solvers. PMID:24204761

    The Beijing genotype is a distinct genetic lineage of Mycobacterium tuberculosis, which is distributed worldwide, and may cause large outbreaks of multidrug resistance-tuberculosis (MDR-TB). The distribution of such strains in the Eastern Mediterranean region (EMR) is unclear, and clarifying the data is our purpose apart from the presence of Beijing TB in Iran. We searched Published literature from CINAHL Cochrane Library, Current Contents, Database of Abstracts of Reviews of Effects (DARE), ProQuest Google Scholar PubMed, PsycINFO, Thomson Reuters, (SID), and Medical Library (MedLib) to detect relevant studies from the year 2000 to July 2015 with the following keywords: M. tuberculosis, Beijing genotype, EMR, and drug resistance. Random-effect models were used to estimate the proportion of Beijing strains in STATA 14. Heterogeneity was investigated by subgroup analysis and meta-regression. The meta-prevalence of Beijing strains was 4% (CI 95% = 3-5). The prevalence was different based on types of detection techniques (spoligotyping = 4% vs. other techniques = 6%; p = 0.003) and years of study (before the year 2000 = 2% vs. after year 2000 = 4%, p = 0.004). The Beijing family was most prevalent in Iran and Pakistan. A strong relationship with drug resistance was reported in Pakistan and Iran, and an increasing trend was seen in Pakistan. Additional studies of drug-resistant TB distribution among Beijing strains in EMR countries are needed as well as a time-trend analysis of the Beijing strain infection in the region.

    Chewing and masticatory function constitutes one of the most important oral health factors that affect quality of life, especially in older individuals. Little consensus currently exists regarding ways to objectively assess clinical masticatory performance (in this context, performance refers an individual's objective ability to mix or comminute food bolus). That said, many methods were developed to assess masticatory performance. Consequently, systematic review of the literature would be of great value when it comes to identifying various methods for objectively assessing clinical masticatory performance and for evaluating these methods. This study protocol describes a systematic review that intends to (i) identify methods to objectively assess clinical masticatory performance and (ii) evaluate psychometric properties (such as validity and reliability) of the identified methods. A systematic literature search is required to do so in these sources: MEDLINE (Ovid), Embase (embase.com), Web of Science Core Collection (Thomson Reuters), Cochrane (Wiley), and Cinahl (Ebsco). studies in scientific, full-text articles; development articles; validation articles; studies of the general adult population, ages ≥18. topics and article types that cover interview methods and self-reported questionnaires; methods/instruments that measure subjective masticatory performance; qualitative studies and case studies; opinion and editorial pieces; animal studies; studies of humans with severe oral health complications. This systematic review will result in a comprehensive assessment of various methods designed to objectively measure clinical masticatory performance. This systematic review will rate these methods, assess their reliability and validity, and identify one or more methods that can be recommended for use in clinical and scientific environments. From what is currently known, no systematic evaluation of various methods for objectively assessing clinical masticatory

    Full Text Available Abstract Background It was recently reported that an interaction of the dopamine D2 receptor (DRD2 and catechol-O-methyltransferase (COMT influences the behavioural approach system – as measured using Carver and White's Behavioural Inhibition and Behavioural Approach System (BIS/BAS scales – in a sample of healthy German subjects. The Temperament and Character Inventory (TCI, in particular the novelty seeking (NS and harm avoidance (HA scales, correlates moderately with the BIS/BAS measure. This study aimed to examine support for an association of DRD2 and COMT with behavioural activation, using the TCI within two independent samples of depressed outpatients (for both samples n = 146. Methods Two clinical samples of depressed patients were ascertained to assess the efficacy of two different pharmacotherapy and psychotherapy treatments. Analysis of variance (ANOVA was used to analyse NS and HA scale and subscale scores with respect to gene loci within each clinical sample. Analysis of covariance were undertaken to examine the association of age and gender with NS and HA scores. An association of age group or gender with gene loci were explored using chi-squared tests, in each sample. Results No significant effect of DRD2 or COMT, either independently or as an interaction, on NS or HA scores was observed, within either sample. Whilst age was significantly negatively associated with NS scores, including age in the two- and three-way interactions did not affect the significance of the association of personality with gene loci. Conclusion This study suggests that the COMT-DRD2 Equilibrium Model of Positive Emotionality recently proposed by Reuter and his colleagues is not applicable amongst currently depressed individuals, whose behavioural approach and inhibition tendencies have been assessed using the TCI.

    The benefits of ursodeoxycholic acid (UDCA) use for treating intra-hepatic cholestasis of pregnancy (ICP) remain uncertain. A 2010 Cochrane Review of randomized control trials was unable to recommend either for or against the use of UDCA in treating ICP. We conducted a meta-analysis of the literature, including both non-randomized studies (NRSs) and RCTs. The objective of the study was to determine if patients included in NRSs were comparable to those in RCTs, and to determine whether the inclusion of NRSs could strengthen the available evidence and guide clinical practice on UDCA use in women with ICP. We searched Medline (Ovid), Embase (Ovid), EMB Reviews, Cinahl (Ebsco), and Web of Knowledge (Thomson Reuters) for articles published from 1966 to June 2012. We included all eligible RCTs of UDCA versus placebo or other treatments, and all NRSs comparing UDCA with any other treatment in women with ICP. We included 11 RCTs (n = 625 pregnancies) and six NRSs (n = 211 pregnancies). The women included in RCTs and NRSs were comparable, but study quality was poorer for NRSs. Overall, women treated with UDCA had decreased pruritus in 73% of RCTs and in 100% of NRSs with available data. Liver function tests were improved in 82% of RCTs and in 100% of NRSs with available data. UDCA use did not affect the Caesarean section rate, but was associated with less prematurity, less use of neonatal intensive care units (data available in only 3/17 studies), and trends towards increased birth weight and decreased meconium staining. There were 0/356 stillbirths with UDCA and 3/399 stillbirths with comparator. UDCA treatment should be recommended for women with ICP to reduce adverse maternal and fetal outcomes.

    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.

    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.

  8. Bt rice expressing Cry2Aa does not harm Cyrtorhinus lividipennis, a main predator of the nontarget herbivore Nilapavarta lugens.

    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.

    Microsurgery has developed significantly since the inception of the first surgical microscope. There have been few attempts to describe "classic" microsurgery articles. In this study citation analysis was done to identify the most highly cited clinical and basic science articles published in five peer-reviewed plastic surgery journals. Thomson/Reuters web of knowledge was used to identify the most highly cited microsurgery articles from five journals: Plastic and Reconstructive Surgery, Annals of Plastic Surgery, Journal of Plastic, Reconstructive & Aesthetic Surgery, Journal of Reconstructive Microsurgery, and Microsurgery. Articles were identified and sorted based on the number of citations and citations per year. The 50 most cited clinical and basic science articles were identified. For clinical articles, number of total citations ranged from 120 to 691 (mean, 212.38) and citations per year ranged from 30.92 to 3.05 (mean, 9.33). The most common defect site was the head and neck (n = 15, 30%), and flaps were perforator and muscle/musculocutaneous flaps (n = 10 each, 20%, respectively). For basic science articles, number of citations ranged from 71 to 332 (mean, 130.82) and citations per year ranged from 2.20 to 11.07 (mean, 5.27). There were 27 animal, 21 cadaveric, and 2 combined studies. The most highly cited microsurgery articles are a direct reflection of the educational and clinical trends. Awareness of the most frequently cited articles may serve as a basis for core knowledge in the education of plastic surgery trainees. III.

    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.

  12. 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

    2017-02-01

    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 20th in the list of countries with highest number of publications on anaesthesiology, however in the last 10 years Turkey moved up to 18th place. Its mean citation number has been 4.64, and it remains the 2nd 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.

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

    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

    The aim of this systematic review was to investigate the short-term (5-10 year mean follow-up) and long-term (10 year or more) survival and success of fixed full arch dental hybrid prosthesis and supporting dental implants. Studies reporting interventions with full-arch fixed dental hybrid prostheses were identified by searching PubMed/Medline (NCBI), Web of Science (Thomson Reuters), the Cochrane Register of Controlled Clinical Trials (EBSCO), and Dentistry and Oral Sciences Source (DOSS; EBSCO) from the earliest available dates through July 17, 2013. Through a series of review process by two examiners, potentially qualifying studies were identified and assessed with respect to the inclusion criteria. A total of 18 studies were included for the quality assessment and the systematic review. Within the limitation of available studies, high short-term survival rates of full arch fixed dental hybrid prostheses (93.3-100%) and supporting implants (87.89-100%) were found. However, the availability of studies investigating long-term outcomes seemed scarce. Furthermore, the included studies were subjected to potential sources of bias (i.e. publication, reporting, attrition bias). Despite seemingly high short-term survival, long-term survival of implant supported full arch fixed dental hybrid prosthesis could not be determined due to limited availability of true long-term studies. Although it may be a valuable option for a patient with a completely edentulous ridge(s), the strategic removal of teeth with satisfactory prognosis for the sake of delivering an implant supported full-arch dental hybrid prosthesis should be avoided.

    Timing of cortisol collection during pregnancy is an important factor within studies reporting on the association between maternal cortisol and depression during pregnancy. Our objective was to further examine the extent to which reported associations differed across studies according to time of maternal cortisol collection during pregnancy. On December 15, 2016, records were identified using PubMed/MEDLINE (National Library of Medicine), EMBASE (Elsevier; 1974-), Cumulative Index to Nursing and Allied Health Literature (CINAHL, EBSCO), PsycINFO (EBSCO), and Web of Science Core Collection (Thomson Reuters). Unique abstracts were screened using the following inclusion criteria: (1) maternal cortisol assessed during pregnancy; (2) antepartum depression assessed during pregnancy using a screening instrument; (3) reports on the association between maternal cortisol and antepartum depression; (4) provides information on timing of cortisol assessment during pregnancy, including time of day and gestation; and (5) not a review article or a case study. One thousand three hundred seventy-five records were identified, resulting in 826 unique abstracts. Twenty-nine articles met all inclusion criteria. On balance, most studies reported no association between maternal cortisol and antepartum depression (N = 17), and saliva and blood were the most common reported matrices. Morning and second and third trimesters were the most common times of collection during pregnancy. Among studies reporting an association (N = 12), second-trimester and third-trimester cortisol assessments more consistently reported an association and elevated cortisol concentrations were observed in expected recovery periods. Our review adds to the existing literature on the topic, highlighting gaps and strategic next steps.

    Cognitive impairment and dementia are associated with a range of cardiovascular conditions, including hypertension, coronary artery disease, and atrial fibrillation. We aimed to describe the association with heart failure, summarizing published data to give estimates of prevalence, incidence, and relative risk of cognitive impairment/dementia in heart failure. We searched multidisciplinary databases including MEDLINE (OVID), EMBASE (OVID), CINAHL (EBSCO), PsychINFO (EBSCO), Web of Science (Thomson Reuters), and CENTRAL (Cochrane Library) from inception until May 31, 2015. All relevant studies looking at cognitive impairment/dementia in heart failure were included. Studies were selected by 2 independent reviewers using prespecified inclusion/exclusion criteria. Where data allowed, we performed meta-analysis and pooled results using random effects models. From 18,000 titles, 37 studies were eligible (n = 8411 participants). Data from 4 prospective cohorts (n = 2513 participants) suggest greater cognitive decline in heart failure compared with non-heart failure over the longer term. These data were not suitable for meta-analysis. In case control studies describing those with and without heart failure (n = 4 papers, 1414 participants) the odds ratio for cognitive impairment in the heart failure population was 1.67 (95% confidence interval 1.15-2.42). Prevalence of cognitive impairment in heart failure cohorts (n = 26 studies, 4176 participants) was 43% (95% confidence interval 30-55). This review suggests a substantial proportion of patients with heart failure have concomitant cognitive problems. This has implications for planning treatment and services. These data do not allow us to comment on causation, and further work is needed to describe the underlying pathophysiology. Copyright © 2017 Elsevier Inc. All rights reserved.

    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 .

    Given the current rate of obesity in the USA, it has been estimated that close to half of the US adult population could be obese by 2030, resulting in greater demand for bariatric procedures. Our objective was to analyze malpractice litigation related to bariatric surgery. We conducted a retrospective review of Westlaw (Thompson Reuters) of all bariatric operations that resulted in the filing of a malpractice claim. Each case was reviewed for pertinent medicolegal information related to the procedure, claim, and trial. The search criteria yielded 298 case briefs, of which 140 met inclusion criteria. Thirty-two percent (n = 49) of cases involved male plaintiffs (patients). Mean patient age with standard deviation (SD) was 43 (10) years. The most common procedure litigated was the Roux-en-Y gastric bypass (76 %, n = 107). Overall, the most common alleged reason for a malpractice claim was delay in diagnosis or management of a complication in the postoperative period (n = 66, 47 %), the most common of which was an anastomotic leak (45 %, n = 34). Death was reported in 74 (52 %) cases. Fifty-seven cases (47 %) were decided in favor of the plaintiff (patient), with a median award payout of $1,090,000 (interquartile range [IQR] $412,500 to $2,550,000). Delay in diagnosing or managing complications in the postoperative setting, most commonly an anastomotic leak, accounted for the majority of malpractice claims. Measures taken to identify and address anastomotic leaks and other complications early in the postoperative period could potentially reduce the amount of filed malpractice claims related to bariatric surgery.

    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.

    2015-12-08

    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.

    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.

    Full Text Available Abstract Background Document classification is a wide-spread problem with many applications, from organizing search engine snippets to spam filtering. We previously described Textpresso, a text-mining system for biological literature, which marks up full text according to a shallow ontology that includes terms of biological interest. This project investigates document classification in the context of biological literature, making use of the Textpresso markup of a corpus of Caenorhabditis elegans literature. Results We present a two-step text categorization algorithm to classify a corpus of C. elegans papers. Our classification method first uses a support vector machine-trained classifier, followed by a novel, phrase-based clustering algorithm. This clustering step autonomously creates cluster labels that are descriptive and understandable by humans. This clustering engine performed better on a standard test-set (Reuters 21578 compared to previously published results (F-value of 0.55 vs. 0.49, while producing cluster descriptions that appear more useful. A web interface allows researchers to quickly navigate through the hierarchy and look for documents that belong to a specific concept. Conclusion We have demonstrated a simple method to classify biological documents that embodies an improvement over current methods. While the classification results are currently optimized for Caenorhabditis elegans papers by human-created rules, the classification engine can be adapted to different types of documents. We have demonstrated this by presenting a web interface that allows researchers to quickly navigate through the hierarchy and look for documents that belong to a specific concept.

    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.

    Abstract: 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); the 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

    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.

    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.

  8. Early-season host switching in Adelphocoris spp. (Hemiptera: Miridae of differing host breadth.

    Full Text Available The mirid bugs Adelphocoris suturalis (Jakovlev, Adelphocoris lineolatus (Goeze and Adelphocoris fasciaticollis (Reuter (Hemiptera: Miridae are common pests of several agricultural crops. These three species have vastly different geographical distributions, phenologies and abundances, all of which are linked to their reliance on local plants. Previous work has shown notable differences in Adelphocoris spp. host use for overwintering. In this study, we assessed the extent to which each of the Adelphocoris spp. relies on some of its major overwinter hosts for spring development. Over the course of four consecutive years (2009-2012, we conducted population surveys on 77 different plant species from 39 families. During the spring, A. fasciaticollis used the broadest range of hosts, as it was found on 35 plant species, followed by A. suturalis (15 species and A. lineolatus (7 species. Abundances of the species greatly differed between host plants, with A. fasciaticollis reaching the highest abundance on Chinese date (Ziziphus jujuba Mill., whereas both A. suturalis and A. lineolatus preferred alfalfa (Medicago sativa L.. The host breadths of the three Adelphocoris spp. differed greatly between subsequent spring and winter seasons. The generalist species exhibited the least host fidelity, with A. suturalis and A. lineolatus using 8 of 22 and 4 of 12 overwinter host species for spring development, respectively. By contrast, the comparative specialist A. fasciaticollis relied on 9 of its 11 overwinter plants as early-season hosts. We highlight important seasonal changes in host breadth and interspecific differences in the extent of host switching behavior between the winter and spring seasons. These findings benefit our understanding of the evolutionary interactions between mirid bugs and their host plants and can be used to guide early-season population management.

    18 F-florbetaben 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 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-florbetaben. 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-florbetaben to predict the progression from MCI to Alzheimer's disease dementia (ADD) or other dementias has not yet been systematically evaluated. To determine the DTA of the 18 F-florbetaben PET scan for detecting people with MCI at time of performing the test who will clinically progress to ADD, other forms of dementia (non-ADD), or any form of dementia at follow-up. The most recent search for this review was performed in May 2017. We searched MEDLINE (OvidSP), Embase (OvidSP), PsycINFO (OvidSP), BIOSIS Citation Index (Thomson Reuters Web of Science), Web of Science Core Collection, including the Science Citation Index (Thomson Reuters Web of Science) and the Conference Proceedings Citation Index (Thomson Reuters Web of Science), LILACS (BIREME), CINAHL (EBSCOhost), ClinicalTrials.gov (https://clinicaltrials.gov), and the World Health Organization International Clinical Trials Registry Platform (WHO ICTRP) (http://www.who.int/ictrp/search/en/).

    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

    Full Text Available Objective The aim of the present study was to investigate the effect of yeast with bacteriocin and Lactobacillus cultures (mixture of Lactobacillus agilis BCRC 10436 and Lactobacillus reuteri BCRC 17476 supplements, alone or in combination, on broiler chicken performance. 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

    "Publish or perish" is the time-honored "principle" for academicians who race to accumulate lines under the "publications" section of a curriculum vitae. The original intent of publication-to inform others of findings and further scientific knowledge-has been corrupted by factors including (1) exponential growth of journals and the journal industry, fueled in part by intrusion of the Internet into all aspects of academic life; and (2) adoption of journal metrics (rather than written content) as the measure of scientific quality. The proprietary Thomson Reuters Impact Factor is the most pernicious metric, having caused editors and publishers to change editorial practices to boost the number. At the same time, gullible administrators and government agencies have been persuaded that metrics for the journal in which materials are published can be used as a measure of the worth of individual investigators (and institutions) and their research efforts: simple numbers can be substituted for the burdensome effort required to read and assess research quality. Thus, granting of research funds, awarding of academic rank and tenure, and determination of salaries (including bonus payments) have become tied to manipulable journal metrics rather than the significance or quality of reported research. Therefore, it is no wonder that the integrity of science is more often being questioned. How should a young investigator approach the "publish or perish" dilemma? Performing sound research and preparing optimal materials for publication must remain the overriding goals: properly articulate the question addressed by the study; thoroughly document all methods and case information; carefully describe results including any conflicting or negative findings; discuss the importance of the findings along with how the results address the initial question and whether findings refute or confirm previous studies; prepare properly cited bibliographic references; list all author contributions

    Estimates suggest that more than 25,000 to 125,000 people die annually from snakebite envenomation worldwide. In contrast to this major disease burden, thorough bibliometric studies do not exist so far that illustrate the overall research activity over a long time span. Therefore, the NewQIS-platform conducted an analysis on snakebite envenoming using the Thomson Reuters database Web of Science. To determine and assess changes regarding the scientific activities and to specifically address the more recent situation we analyzed two time intervals (t). During the first time interval from 1900 to 2007 (t1) 13,015 publications (p) were identified. In the following period (2008–2016 = t2) 4,982 publications were identified by the same search strategy. They originate from 114 (t1) respectively 121 countries (t2), with the USA (p = 3518), Brazil (p = 1100) and Japan (p = 961) being most productive in the first period, and the USA (p = 1087), Brazil (p = 991) and China (p = 378) in the second period, respectively. Setting the publication numbers in relation to GDP/capita, Brazil leads with 92 publications per 10,000 Int$GDP/capita, followed by India with 79 publications per 10000 Int$GDP/capita (t1). Comparing the country’s publication activity with the Human Development Index level indicates that the majority of the publications is published by highly developed countries. When calculating the average citation rates (citations per published item = CR) mainly European countries show the highest ranks: From 1900–2007 Sweden ranks first with a CR = 27, followed by the Netherlands (CR = 24.8), Switzerland (CR = 23), Spain, Austria and the USA (CR = 22). From 2008 to 2016 the highest rate achieves Switzerland with a value of 24.6, followed by Belgium (CR = 18.1), Spain (CR = 16.7), Costa Rica (CR = 14.9) and Netherlands (CR = 14). Compared with this, the USA was placed at rank 13 (CR = 9,5). In summary, the present study represents the first density-equalizing map

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

    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
