Article 19: Global Campaign for Free Expression  

Science.gov (United States)

Along with other global campaigns to affect social and political transformation (such as Amnesty International), Article 19 is an organization designed "to combat censorship by promoting freedom of expression and access to official information." With offices in London and South Africa, the organization has partners in over 30 countries, and monitors, researches, publishes, and litigates on behalf of freedom of expression around the world. Certainly one of the first stops on the site should be the Virtual Handbook of Expression, which contains a number of briefs of freedom of expression cases from the UN Human Rights Committee, the Inter-American Commission and Court on Human Rights, the African Commission on Human and Peoples' Rights and the European Commission and Court of Human Rights. In addition, the Virtual Handbook contains a number of key documents, organized around themes that include such timely topics as defamation, national security, print regulation, and privacy. Of course, visitors will also find a great deal of additional material here, including information on Article 19's work in Africa, Asia, the Middle East, and a publication archive as well.

A contrastive analysis of the use of modal verbs in the expression of epistemic stance in Business Management research articles in English and Spanish  

Directory of Open Access Journals (Sweden)

Full Text Available In the present paper an intercultural quantitative and qualitative analysis of the use of modal verbs as epistemic stance markers in SERAC (Spanish-English Research Article Corpus, a corpus of research articles (RAs in different disciplines, is carried out. The corpus selected for this research consists of 48 Business Management research articles. Special emphasis is laid on the introduction and discussion sections of RAs, where stance devices are most frequently located to pursue convergence with the readership. This kind of intercultural analysis has been achieved through both a bottom-up research approach and a top-down research approach. The results obtained in this study point in the direction that there are obvious differences between the use of modal verbs by native writers and the use of modal verbs by non-native Spanish writers. The most remarkable aspect is that Spanish writers show a deviant handling of hedges and boosters. Therefore, they have difficulties in establishing a proper tenor when they write in English.

Description of research design of articles published in four Brazilian physical therapy journals  

Science.gov (United States)

Background While the research design of articles published in medical journals and in some physical therapy journals has already been evaluated, this has not been investigated in Brazilian physical therapy journals. Objective To describe the research design used in all articles published in Brazilian scientific journals that are freely available, have high Qualis rankings, and are relevant to physical therapy over a 7-year period. Method We extracted the bibliometric data, research design, research type (human or animal), and clinical area for all articles published. The articles were grouped into their level of evidence, and descriptive analyses were performed. We calculated the frequency, proportions of articles, and 95% confidence interval of these proportions with each research design in each journal. We cross-tabulated the clinical areas with research designs (expressed as number and percentages). Results A total of 1,458 articles from four Brazilian journals were found: Revista Brasileira de Fisioterapia, Revista Fisioterapia em Movimento, Revista Fisioterapia e Pesquisa, and Revista Acta Fisiátrica. The majority of articles were classified as level II of evidence (60%), followed by level III (29%) and level I (10%). The most prevalent research designs were cross-sectional studies (38%), single-case or case-series studies, and narrative reviews. Most articles reported human research and were in the musculoskeletal, neurologic, and cardiothoracic areas. Conclusions Most of the research published in Brazilian physical therapy journals used levels II and III of evidence. Increasing the publication rate of systematic reviews and randomized controlled trials would provide more high-quality evidence to guide evidence-based physical therapy practice. PMID:24675913

Writing business research article abstracts: A genre approach  

Directory of Open Access Journals (Sweden)

Full Text Available A great deal has been published about oral and written genres in business (e.g., letters, research articles, oral presentations, etc., and less attention has been paid to business research article abstracts as a written genre, as many experts would argue. This research intends to raise rhetorical awareness about the role of abstracts in today’s academic world. To this effect, the abstracts of two official publications of the Association of Business Communication, Journal of Business Communication and Business Communication Quarterly, have been analyzed and compared in terms of structure and content according to models published in the specialized literature. The results show an irregular and inconsistent presentation of abstracts, a good number of them following no set pattern and thus lacking in important information for researchers. These findings suggest, first of all, that abstracts have a specific mission to fulfil and should not be disregarded; and, secondly, that journal guidelines for authors should be more explicit in their instructions on how to write and structure abstracts.

Adverbial stance marking in the introduction and conclusion sections of legal research articles  

Directory of Open Access Journals (Sweden)

Full Text Available Although scientific research articles have traditionally been taken as examples of an objective style of writing that aims to minimise researchers’ voices in their texts (Gilbert and Mulkay, 1984:42, authors inevitably adopt stances towards the information presented and the target audience when writing their papers. This article explores authorial stance as expressed by adverbial markers in the introduction and conclusion sections of legal research papers. Following Biber et al. (1999, and Conrad and Biber (1999, our aim is to identify the most frequent adverbial markers of stance present in each section as indicators of (i epistemicity, (ii attitude, and (iii style. We will try to show whether or not there are functional differences in the use of adverbial stance markers, and whether or not these are derived from the different communicative purposes of these sections.

Open Access Articles Have a Greater Research Impact Than Articles Not Freely Available, A review of: Antelman, Kristin. “Do Open-Access Articles Have a Greater Research Impact?” College & Research Libraries 65.5 (Sep. 2004: 372-82.  

Directory of Open Access Journals (Sweden)

Full Text Available Objective – To ascertain whether open access articles have a greater research impact than articles not freely available, as measured by citations in the ISI Web of Science database. Design – Analysis of mean citation rates of a sample population of journal articles across four disciplines. Setting – Journal literature across the disciplines of philosophy, political science, mathematics, and electrical and electronic engineering. Subjects – A sample of 2,017 articles across the four disciplines published between 2001 and 2002 (for political science, mathematics, and electrical and electronic engineering and between 1999 and 2000 (for philosophy. Methods – A systematic presample of articles for each of the disciplines was taken to calculate the necessary sample sizes. Based on this calculation, articles were sourced from ten leading journals in each discipline. The leading journals in political science, mathematics, and electrical and electronic engineering were defined by ISI’s Journal Citation Reports for 2002. The ten leading philosophy journals were selected using a combination of other methods. Once the sample population had been identified, each article title and the number of citations to each article (in the ISI Web of Science database were recorded. Then the article title was searched in Google and if any freely available full text version was found, the article was classified as open access. The mean citation rate for open access and non?open access articles in each discipline was identified, and the percentage difference between the means was calculated. Main results – The four disciplines represented a range of open access uptake: 17% of articles in philosophy were open access, 29% in political science, 37% in electrical and electronic engineering, and 69% in mathematics. There was a significant difference in the mean citation rates for open access articles and non?open access articles in all four disciplines. The percentage difference in means was 45% in philosophy, 51% in electrical and electronic engineering, 86% in political science, and 91% in mathematics. Mathematics had the highest rate of open access availability of articles, but political science had the greatest difference in mean citation rates, suggesting there are other, discipline?specific factors apart from rate of open access uptake affecting research impact. Conclusion – The finding that, across these four disciplines, open access articles have a greater research impact than non?open access articles, is only one aspect of the complex changes that are presently taking place in scholarly publishing and communication. However, it is useful information for librarians formulating strategies for building institutional repositories, or exploring open access publishing with patrons or publishers.

Invited Review Article: Advanced light microscopy for biological space research  

Science.gov (United States)

As commercial space flights have become feasible and long-term extraterrestrial missions are planned, it is imperative that the impact of space travel and the space environment on human physiology be thoroughly characterized. Scrutinizing the effects of potentially detrimental factors such as ionizing radiation and microgravity at the cellular and tissue level demands adequate visualization technology. Advanced light microscopy (ALM) is the leading tool for non-destructive structural and functional investigation of static as well as dynamic biological systems. In recent years, technological developments and advances in photochemistry and genetic engineering have boosted all aspects of resolution, readout and throughput, rendering ALM ideally suited for biological space research. While various microscopy-based studies have addressed cellular response to space-related environmental stressors, biological endpoints have typically been determined only after the mission, leaving an experimental gap that is prone to bias results. An on-board, real-time microscopical monitoring device can bridge this gap. Breadboards and even fully operational microscope setups have been conceived, but they need to be rendered more compact and versatile. Most importantly, they must allow addressing the impact of gravity, or the lack thereof, on physiologically relevant biological systems in space and in ground-based simulations. In order to delineate the essential functionalities for such a system, we have reviewed the pending questions in space science, the relevant biological model systems, and the state-of-the art in ALM. Based on a rigorous trade-off, in which we recognize the relevance of multi-cellular systems and the cellular microenvironment, we propose a compact, but flexible concept for space-related cell biological research that is based on light sheet microscopy.

Communication research in Spain, 1998-2007. An analysis of articles published in Spanish communication journals  

Directory of Open Access Journals (Sweden)

Full Text Available The growth of communication research in Spain in the last decade contrasts with the scarcity of works trying to describe and assess the quality of this research. Attempting to address this problem, this article presents a quantitative content analysis of all the articles published in four years between 1998 and 2007 (1998, 2002, 2003 and 2007 by four of the most important Spanish communication journals, with a total sample of 285 articles, of which 235 are from authors working in Spanish universities or research centres. Results show that the Spanish communication researchers are basically interested in the study of Journalism, and more specifically in the analysis of news discourses. Another finding is that most research is empirically-oriented, but by and large lacks methodological rigour. These deficiencies were decreasing during the period under analysis, but increased once again in the works published more recently.

Citation analysis as a measure of article quality, journal influence and individual researcher performance  

International Nuclear Information System (INIS)

The research-related performance of universities, as well as that of individual researchers, is increasingly evaluated through the use of objective measures, or metrics, which seek to support or in some cases even replace more traditional methods of peer review. In particular there is a growing awareness in research communities, government organisations and funding bodies around the concept of using evaluation metrics to analyse research citations. The tools available for ‘citation analysis’ are many and varied, enabling a quantification of scientific quality, academic impact and prestige. However there is increasing concern regarding the potential misuse of such tools, which have limitations in certain research disciplines. This article uses ‘real world’ examples from radiography research and scholarship to illustrate the range of currently available citation analysis tools. It explores the academic debate surrounding their strengths and limitations, and identifies the potential impact of citation analysis on the radiography research community. The article concludes that citation analysis is a valuable tool for researchers to use for personal reflection and research planning, yet there are inherent dangers if it is used inappropriately. Whilst citation analysis can give objective information regarding an individual, research group, journal or higher education institution, it should not be used as a total substitute for traditional qualitative review and peer ional qualitative review and peer assessment.

Research on Dynamic Facial Expressions Recognition  

Directory of Open Access Journals (Sweden)

Full Text Available Human-computer intelligent interaction (HCII is usually based on facial expression recognition. A dynamic facial expression recognition method based on video sequence is proposed in this paper, which uses Gaussian of Mixture Hidden Markov Model. Firstly, we get some special facial expression regions, in which the motion features are extracted and described as phase form and then constituted to eigen-sequences. Secondly we use Gaussian of Mixture Hidden Markov Model to learn and test these eigen-sequences, and recognize six universal facial expressions: angry, disgust, fear, happy, sad and surprise. And we developed an experimental system based on our algorithm. The experimental results show that the computing time and the error of vector quantization is reduced, while the classification efficiency is improved.

Rhetorical Variation across Research Article Abstracts in Environmental Science and Applied Linguistics  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract is of a pivotal genre in scientific communication, assisting not only highly selective readers with judgment of the pertinent articles but also researchers in disseminating new knowledge and intellectual discoveries. Difficult yet challenging, however, is the task of writing effective abstracts particularly among non-English speaking scholars. This study reports on the identification of moves and co-existing linguistic features commonly used in environmental science and applied linguistics research article abstracts. 200 research article abstracts published during the years of 2010-2013 were analyzed with reference to Hyland’s analytical framework. The two-tier analysis reveals a typical rhetorical structure including a cluster of linguistic features associated with certain pieces of information presented in each particular move, elucidating how research article abstracts in both fields are conventionally constructed. With the presence of all five moves, the structures of I-P-M-Pr-C and P-M-Pr-C were most prevalent among the corpus of environmental science and applied linguistics, respectively. All of the moves, except for Introduction move, were conventional across the two disciplines. Pedagogical implications of the findings are useful particularly for academic reading and writing instruction, enabling language teachers to empower their learners with strategies that contribute to the enhancement of success for publishing in scholarly leading publication.

The Article Idea Chart: A participatory action research tool to aid involvement in dissemination  

Directory of Open Access Journals (Sweden)

Full Text Available Participatory-action research encourages the involvement of all key stakeholders in the research process and is especially well suited to mental health research. Previous literature outlines the importance of engaging stakeholders in the development of research questions and methodologies, but little has been written about ensuring the involvement of all stakeholders (especially non-academic members in dissemination opportunities such as publication development. The Article Idea Chart was developed as a specific methodology for engaging all stakeholders in data analysis and publication development. It has been successfully utilised in a number of studies and is an effective tool for ensuring the dissemination process of participatory-action research results is both inclusive and transparent to all team members, regardless of stakeholder group.Keywords: participatory-action research, mental health, dissemination, community capacity building, publications, authorship

Longitudinal study on patent citations to academic research articles in nanotechnology (1976-2004)  

International Nuclear Information System (INIS)

Academic nanoscale science and engineering (NSE) research provides a foundation for nanotechnology innovation reflected in patents. About 60% or about 50,000 of the NSE-related patents identified by 'full-text' keyword searching between 1976 and 2004 at the United States Patent and Trademark Office (USPTO) have an average of approximately 18 academic citations. The most cited academic journals, individual researchers, and research articles have been evaluated as sources of technology innovation in the NSE area over the 28-year period. Each of the most influential articles was cited about 90 times on the average, while the most influential author was cited more than 700 times by the NSE-related patents. Thirteen mainstream journals accounted for about 20% of all citations. Science, Nature and Proceedings of the National Academy of Sciences (PNAS) have consistently been the top three most cited journals, with each article being cited three times on average. There is another kind of influential journals, represented by Biosystems and Origin of Life, which have very few articles cited but with exceptionally high frequencies. The number of academic citations per year from ten most cited journals has increased by over 17 times in the interval (1990-1999) as compared to (1976-1989), and again over 3 times in the interval (2000-2004) as compared to (1990-1999). This is an indication of increased used of academic knowledge creation in the NSE-related patentsthe NSE-related patents

Lifestyle Factors in Hypertension Drug Research: Systematic Analysis of Articles in a Leading Cochrane Report  

Science.gov (United States)

Established standards for first-line hypertension management include lifestyle modification and behavior change. The degree to which and how lifestyle modification is systematically integrated into studies of first-line drug management for hypertension is of methodological and clinical relevance. This study systematically reviewed the methodology of articles from a recent Cochrane review that had been designed to inform first-line medical treatment of hypertension and was representative of high quality established clinical trials in the field. Source articles (n = 34) were systematically reviewed for lifestyle interventions including smoking cessation, diet, weight loss, physical activity and exercise, stress reduction, and moderate alcohol consumption. 54% of articles did not mention lifestyle modification; 46% contained nonspecific descriptions of interventions. We contend that hypertension management research trials (including drug studies) need to elucidate the benefits and risks of drug-lifestyle interaction, to support the priority of lifestyle modification, and that lifestyle modification, rather than drugs, is seen by patients and the public as a priority for health professionals. The inclusion of lifestyle modification strategies in research designs for hypertension drug trials could enhance current research, from trial efficacy to clinical outcome effectiveness, and align hypertension best practices of a range of health professionals with evidence-based knowledge translation.

Persistence of information on the web: Analyzing citations contained in research articles  

DEFF Research Database (Denmark)

We analyze the persistence of information on the web, looking at the percentage of invalid URLs contained in academic articles within the CiteSeer (ResearchIndex) database. The number of URLs contained in the papers has increased from an average of 0.06 in 1993 to 1.6 in 1999. We found that a significant percentage of URLs are now invalid, ranging from 23% for 1999 articles, to 53% for 1994. We also found that for almost all of the invalid URLs, it was possible to locate the information (or highly related information) in an alternate location, primarily with the use of search engines. However, the ability to relocate missing information varied according to search experience and effort expended. Citation practices suggest that more information may be lost in the future unless these practices are improved. We discuss persistent URL standards and their usage, and give recommendations for citing URLs in research articles as well as for finding the new location of invalid URLs.

Discoursive analysis and pragmatic metadiscourse in four sub-areas of Economics research articles  

Directory of Open Access Journals (Sweden)

Full Text Available English for Specific Purposes (ESP and English for Academic Purposes (EAP are two disciplines whose importance has been growing lately. This is due to the ever-increasing interest in the language that describes the most recent developments in varying disciplines and the need to communicate in and understand that language. One of the means for the spreading of those new developments in the different technologies is through research articles inspecialised journals. These impose certain rules that must be fulfilled by all researchers who want to see their papers published. Much literature has been written about this, covering most linguistic areas (see, for instance, Bazerman, 1988; Bhatia, 1993; Dudley-Evans, 1994; Fortanet, 2002. Many articles contrast different genres but rarely distinguish different sub-areas within a genre (Bridgman & Carlson, 1984; Malcolm, 1987; Hyland, 1988; Neff Van Aertselaer, 2006. In the present case, we will consider texts within the discipline of Economics. The aim of this paper is to show a structural, grammatical and metatextual analysis of ten articles recently published in very prestigious specialised publications, covering the most important areas of study in Economics. We conclude by making a contrastive rhetorical analysis of the four sub-genres analysed here. These are: Applied Economy, Quantitative Economy, Financial Economy, and Management and Business.

Stylistic Features of Scientific English: A Study of Scientific Research Articles  

Directory of Open Access Journals (Sweden)

Full Text Available This study intends to explore what stylistic features characterize scientific English and make it different from any other language used in any other discipline. What are certain areas of language that are used more frequently in science than in non-science oriented language texts? This paper deals with the linguistic features concerning the application of vocabulary, grammar, discourse and style used in scientific English. A comparative analysis of literary and scientific language has been undertaken to make the nature and discourse of scientific English clearer. It was found that scientific use of English is marked with accuracy, precision and objective interpretation of facts and findings whereas literary language is subjective interpretation of life. Literary language contains literary impulse and represents the artist's inner self and his spontaneous overflow of feeling whereas scientific language represents universal truth and verifiable research findings. Scientific research papers drawn from Medical and Natural sciences were analyzed and it was found that frequent occurrence of Passive Voice in Method Section of scientific research articles makes scientific research findings impersonal and universal. Scientists use Passive Voice most often in order to get rid of personal whims and fancies. Many other features of scientific English such as nominalization and ‘interrogative gambit’ which occur frequently as unique discourse features in scientific research journals have also been taken into account in this study.

25th anniversary article: a decade of organic/polymeric photovoltaic research.  

Science.gov (United States)

Organic photovoltaic (OPV) technology has been developed and improved from a fancy concept with less than 1% power conversion efficiency (PCE) to over 10% PCE, particularly through the efforts in the last decade. The significant progress is the result of multidisciplinary research ranging from chemistry, material science, physics, and engineering. These efforts include the design and synthesis of novel compounds, understanding and controlling the film morphology, elucidating the device mechanisms, developing new device architectures, and improving large-scale manufacture. All of these achievements catalyzed the rapid growth of the OPV technology. This review article takes a retrospective look at the research and development of OPV, and focuses on recent advances of solution-processed materials and devices during the last decade, particular the polymer version of the materials and devices. The work in this field is exciting and OPV technology is a promising candidate for future thin film solar cells. PMID:24105687

Inferential Discourse Markers in Discussion Section of Psychology Research Articles across English and Persian  

Directory of Open Access Journals (Sweden)

Full Text Available The use of inferential discourse markers (IDMs as a linguistic device implies significant results in satisfying conversational coherence. Therefore, with the aim of investigating their distribution of the use, this study was developed across three different sets of psychology articles written by English native speakers (NS, Persian non-native speakers (PNNS and Persian native speakers (PNS during the years 2005 to 2010.To this aim, Fraser’s (1999, and Halliday and Hasan’s (1976 suggested taxonomies were adopted in the analysis of IDMs in the discussion section of 198 psychological research articles. As a result, two micro- (13 minor categories and macro-levels (3 major categories analyses of the IDMs were presented. The extent of difference in the type and frequency of use was then assessed through Chi- square across these examined groups. Based on the findings, the extent of difference was significant (p<0.05 at the micro-level, yet insignificant (p>0.05 at macro-level. Although therefore and thus were the commonest markers for all the native and non-native writers, there was a higher record of the former in the English articles written by Persian speakers (38%. Yet, the latter was more frequent among the English native speakers (34.9%. On the other hand, the major function of general causal relation proved as the common type of IDMs across all three groups of articles. The findings may promise some implications for syllabus designers, material developers and language practitioners, as well.

Analyses of Move Structure and Verb Tense of Research Article Abstracts in Applied Linguistics  

Directory of Open Access Journals (Sweden)

Full Text Available This study examined 90 research article abstracts in three applied linguistics journals (i.e., TESOL Quarterly, Applied Linguistics, and Language Learning from two dimensions: the move structure features and the verb tense of each move. The results showed that the abstracts analyzed tended to take a four-move structure instead of a five-move one as proposed in literature. In addition, since some publishers have word limits on abstract length, authors would usually follow the publisher’s guideline accordingly, thus there existing some differences concerning the move structure features among the abstracts in the three journals. In terms of the verb tense in each move, the preferred pattern was as follows: the present tense usually occurred in the first, second, and fifth move, while the past tense was often used in the third and fourth moves. It was also found that there were some variations between the abstracts written by native speakers and nonnative speakers of English. It is hoped that with detailed analyses of abstracts, the results of this study may serve as a complement to the guidelines for novice writers to construct a proper research article abstract in applied linguistics.

Validity of claims made in weight management research: a narrative review of dietetic articles  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background The best available evidence demonstrates that conventional weight management has a high long-term failure rate. The ethical implications of continued reliance on an energy deficit approach to weight management are under-explored. Methods A narrative literature review of journal articles in The Journal of Human Nutrition and Dietetics from 2004 to 2008. Results Although the energy deficit approach to weight management has a high long-term failure rate it continues to dominate research in the field. In the current research agenda, controversies and complexities in the evidence base are inadequately discussed, and claims about the likely success of weight management misrepresent available evidence. Conclusions Dietetic literature on weight management fails to meet the standards of evidence based medicine. Research in the field is characterised by speculative claims that fail to accurately represent the available data. There is a corresponding lack of debate on the ethical implications of continuing to promote ineffective treatment regimes and little research into alternative non-weight centred approaches. An alternative health at every size approach is recommended.

El metadiscurso interpersonal en artículos de investigación / Interpersonal metadiscourse in research articles  

Scientific Electronic Library Online (English)

Full Text Available SciELO Chile | Language: Spanish Abstract in spanish En este artículo se presentan los resultados del análisis de una muestra de quince artículos de la Revista de Pedagogía con el objetivo de determinar la manera cómo los investigadores de la educación se interrelacionan con sus pares y comunican su posición y su compromiso con la disciplina. Para ell [...] o se identificaron las marcas metadiscursivas y su frecuencia de uso según las categorías de metadiscurso interpersonal propuestas por Hyland (1999a, 2000): mitigadores, enfatizadores, marcadores de actitud, marcadores relacionales y marcadores de persona. Los resultados revelan cierta variabilidad en el uso de las marcas interpersonales, la cual podría estar vinculada al tipo de investigación. La mitigación constituyó el rasgo más frecuente seguido por los marcadores relacionales y actitudinales. Se concluye que los investigadores de la educación tienen una tendencia a no imponer sus puntos de vista, muestran preocupación por proyectarse como persona y por persuadir a sus lectores para que estos acepten sus argumentos. Abstract in english This article reports on the results of the analysis of a sample of fifteen articles extracted from the journal Revista de Pedagogía in order to determine how education researchers interact with their peers and communicate their integrity and their compromise with the discipline. The analysis focused [...] on the interpersonal metadiscourse category and its dimensions as proposed by Hyland (1999a, 2000): hedges, boosters, attitude markers, relational markers and person markers. The results reveal that the variability in the use of interpersonal markers could be linked to the type of research. Hedging constituted the most frequent trait followed by relation and attitude markers. I conclude that education researchers have a tendency not to impose their point of views. They are concerned with personal stance and with assuring that their arguments are accepted by their readers.

Article Expression, Purification, and Characterization of Cu/ZnSOD from Panax Ginseng  

Directory of Open Access Journals (Sweden)

Full Text Available Superoxide dismutase (SOD has a strong antioxidant effect, but the traditional SOD extraction method is not the most efficient method of SOD amplification. In this study, we report the cloning of the Cu/ZnSOD gene from Panax ginseng into a temperature-regulated expression plasmid, pBV220. Cu/ZnSOD inclusion bodies were expressed in E. coli at a high level. Then, the inclusion bodies were purified by ion-exchange chromatography and molecular sieve chromatography. Finally, we obtained stable SOD in the bacterial broth, with a protein content of 965 mg/L and enzyme specific activity of 9389.96 U/mg. These results provide a foundation for future studies on the antioxidant mechanisms of ginseng and the development and application of ginseng Cu/ZnSOD.

‘Extending this claim, we propose…’ The writer’s presence in research articles from different disciplines  

Directory of Open Access Journals (Sweden)

Full Text Available In today’s academic world, creating an appropriate authorial identity by means of self-mention resources is essential to project an image of competence and reliability in research articles (RAs, and to highlight the relevance of one’s contributions. This paper offers quantitative and qualitative data on the use of exclusive first person markers in RAs from four different disciplines, namely Applied Linguistics, Business Management, Food Technology and Urology, complemented by insights from specialist informants in each of the fields. Moreover, the main discourse functions performed by authors when using exclusive “we” have been studied. The results indicate that there are significant variations in the frequency of these resources and in the preferred functions for which they are used across disciplines, although this variation is not entirely consistent with the dichotomy between hard and soft sciences.

Research Article Abstracts in Two Related Disciplines: Rhetorical Variation between Linguistics and Applied Linguistics  

Directory of Open Access Journals (Sweden)

Full Text Available The previous studies on abstracts (e.g., Santos, 1996; Samraj, 2002; Pho, 2008 illustrate that disciplinary variation in research article abstracts is discernible. However, the studies of abstracts from two related disciplines are still limited. The present study aimed to explore the rhetorical moves of abstracts in the fields of linguistics and applied linguistics by investigating 200 abstracts published between 2009-2012. Hyland’s (2000 model of five rhetorical moves was chosen as the analytical framework for the rhetorical structure. Findings indicated that there were three conventional moves in abstracts in linguistics, while there were four conventional moves in abstracts in applied linguistics. The findings have significant pedagogical implications for academic writing for novice writers in the two disciplines.

Accidentes del verbo en las secciones de artículos de investigación / Verbal Inflection in Research Article Sections  

Scientific Electronic Library Online (English)

Full Text Available SciELO Chile | Language: Spanish Abstract in spanish En este artículo, se describe la variación de los accidentes del verbo en las secciones de artículos de investigación en español. Para ello, se analizaron los accidentes del verbo de 42.086 formas verbales en un corpus representativo de 162 artículos de investigación, pertenecientes a 6 áreas de la [...] ciencia y obtenidos de la base SciELO-Chile. Los resultados generales muestran que los elementos no marcados son siempre más frecuentes, independientemente del área de la ciencia y de la sección. Además, las áreas de la ciencia no afectan los patrones de uso de los verbos. Por último, al analizar la variación por sección, el único accidente que varía sustancialmente es el tiempo verbal. Los resultados de esta investigación son de utilidad para aquellos interesados en la descripción del discurso científico y en la didáctica de la escritura científica. Abstract in english This article attempts to describe verbal inflection variation in research article sections written in Spanish. In order to depict these inflections, we analyzed a corpus of 42.086 verbal forms from 162 research papers. These papers are from six scientific areas and were obtained from the Chilean Sci [...] ELO index. General results show that unmarked elements are always more frequent regardless the scientific area or the section. Besides, we can state that verb patterns are not affected by the scientific area under analysis. Finally, when the sections of the papers were analyzed, we could find out that variation takes place only in tense. These results are useful for both scientific discourse description and the didactics of scientific writing.

From academic research articles to academic visual and video essays: Only a multimodal transition?  

DEFF Research Database (Denmark)

Drawing on an interdisciplinary theoretical framework, we propose to examine multimodal texts from the academic genre set belonging to the field of presenting and discussing research results: the academic research article, the academic visual essay and the academic video essay. The data for this study has been collected from academic journals that belong to print medium and to multimedia. In order to articulate an analytical model for the description and interpretation of these subgenres, we depart from the understanding of genres as linguistic categories influenced by specific situations, and we take into consideration the influence of technological advances upon the development of multimodal genres and the variety of subgenres. Therefore, concepts like remediation and resemiotization that are related to a multimodal approach to genres will be employed. The exploration of these multimodal subgenres will also be facilitated by applying theoretical approaches focused on knowledge communication because the academic discourse in these subgenres is based on specific meaning-making structures. The fact that these structures are linked to the subgenres’ common communicative purpose of representing specific knowledge types implies that it is necessary to explore how the structures are influenced by the choice and interplay of several semiotic modes. We address the semiotic modes’ interaction and combination within the subgenres in order to identify the roles of the semiotic interplay in creating and multiplying meaning at various levels of the generic organization. This paper concludes that it is increasingly necessary to open up the analytical space for the study of new multimodal academic subgenres by integrating the multimodal perspective in the context of genre theory in order to highlight the newest developments in the contemporary realm of research genres.

Full Text Available The use of statistical analysis is important in the biomedical research. Some studies have described the use of statistical methods in research articles, in Peruvian literature has not been done this description. Objective: To describe the frequency of use of statistical methods in five Peruvian biomedical journals in the period 2002-2009. Methods: Bibliometric, descriptive study. We analyzed the original articles of the journals: Peruvian Journal of public health and experimental medicine, Annals of the Faculty of Medicine, Herediana Medical Journal, Science and Medical Research Student of LatinAmerican (CIMEL and Peruvian Journal of Gastroenterology. We performed descriptive and bivariate analysis to identify factors influencing the use of statistical methods. Results: We analyzed 794 original articles, 42,1% of articles were authored by specialized physicians, 41,9% of articles had clinical medicine as their main topic. 41,3% of the articles were cross sectional and 39,1% were descriptive. The most common statistical tests used were descriptive analysis (82.7% of articles, contingency tables (38,5%, Student T-test (15,7% and epidemiologic statistics (12% and non parametric tests (9,3%. The number of articles using descriptive statistics have declined since the year 2002 (p = 0,02. 2,5% of articles not use any type of statistical analysis, 47,9% of articles used a unique statistical test and 49,6% of articles used more than one statistical test. Conclusions: The descriptive analysis is the most common type of analysis in the Peruvian biomedical journal articles, however the frequency of its use has declined in the period analyzed. We recommend studies to evaluate the statistical tests used in Peruvian journals and identify the most frequent types of errors in its use.

A Teaching Strategy with a Focus on Argumentation to Improve Undergraduate Students’ Ability to Read Research Articles  

Science.gov (United States)

The aim of this study is to evaluate a teaching strategy designed to teach first-year undergraduate life sciences students at a research university how to learn to read authentic research articles. Our approach—based on the work done in the field of genre analysis and argumentation theory—means that we teach students to read research articles by teaching them which rhetorical moves occur in research articles and how they can identify these. Because research articles are persuasive by their very nature, we focused on the rhetorical moves that play an important role in authors’ arguments. We designed a teaching strategy using cognitive apprenticeship as the pedagogical approach. It was implemented in a first-year compulsory course in the life sciences undergraduate program. Comparison of the results of a pretest with those of the posttest showed that students’ ability to identify these moves had improved. Moreover, students themselves had also perceived that their ability to read and understand a research article had increased. The students’ evaluations demonstrated that they appreciated the pedagogical approach used and experienced the assignments as useful. On the basis of our results, we concluded that students had taken a first step toward becoming expert readers.

Text mining of full-text journal articles combined with gene expression analysis reveals a relationship between sphingosine-1-phosphate and invasiveness of a glioblastoma cell line  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Sphingosine 1-phosphate (S1P, a lysophospholipid, is involved in various cellular processes such as migration, proliferation, and survival. To date, the impact of S1P on human glioblastoma is not fully understood. Particularly, the concerted role played by matrix metalloproteinases (MMP and S1P in aggressive tumor behavior and angiogenesis remains to be elucidated. Results To gain new insights in the effect of S1P on angiogenesis and invasion of this type of malignant tumor, we used microarrays to investigate the gene expression in glioblastoma as a response to S1P administration in vitro. We compared the expression profiles for the same cell lines under the influence of epidermal growth factor (EGF, an important growth factor. We found a set of 72 genes that are significantly differentially expressed as a unique response to S1P. Based on the result of mining full-text articles from 20 scientific journals in the field of cancer research published over a period of five years, we inferred gene-gene interaction networks for these 72 differentially expressed genes. Among the generated networks, we identified a particularly interesting one. It describes a cascading event, triggered by S1P, leading to the transactivation of MMP-9 via neuregulin-1 (NRG-1, vascular endothelial growth factor (VEGF, and the urokinase-type plasminogen activator (uPA. This interaction network has the potential to shed new light on our understanding of the role played by MMP-9 in invasive glioblastomas. Conclusion Automated extraction of information from biological literature promises to play an increasingly important role in biological knowledge discovery. This is particularly true for high-throughput approaches, such as microarrays, and for combining and integrating data from different sources. Text mining may hold the key to unraveling previously unknown relationships between biological entities and could develop into an indispensable instrument in the process of formulating novel and potentially promising hypotheses.

Research topics, author's specialty, and funding sources of articles published in an emergency medicine journal.  

Science.gov (United States)

All original articles published in JACEP and Annals of Emergency Medicine in 1972, 1975, 1978, and 1981 were reviewed and classified according to topic, author's specialty, and funding source. The number of articles published in each category was as follows: toxicology, 44; emergency medical services (EMS), 34; general surgery, 31; emergency department, 28; educational techniques, 19; orthopedics, 17; cardiovascular disease, 15; pulmonary, 13; cardiopulmonary resuscitation (CPR), 10; shock, 8; airway management, 8; and other, 71. The number of authors per article ranged from one to eight; the mean number of authors increased from 1.1 in 1972 to 2.6 in 1981 (P less than .001). The authors' backgrounds most frequently included were as follows: emergency medicine, 53.4%; surgery, 12.8%; internal medicine, 7.9%; and pediatrics, 1.6%. The percentage of articles with specific funding sources increased from 2.9% in 1972 to 25% in 1978, then decreased to 14.3% in 1981. The percentage for each funding source was as follows: government, 7.9%; industry, 2.0%; university, 3.3%; foundation, 2.0%; other, 1.0%; and none, 83.8%. This study demonstrates that there is a defined body of knowledge in emergency medicine, that emergency physicians author the majority of publications in this emergency medicine journal, and that emergency medicine is not supported by traditional funding sources.

Comparing indicators of authorial stance in psychology students’ writing and published research article  

Directory of Open Access Journals (Sweden)

Full Text Available This article presents the results of a pilot study examining the use of first-person pronouns, certain adjectives and grading adverbs in a corpus of 51 French psychology student papers written in English as a second language. These results were compared to a corpus of published psychology articles and to a sub-corpus of psychology student texts from the British Academic Written English corpus (BAWE. Strategic use of pairs of evaluative words was found in the students’ texts but not in the published texts. However, the variables of native language and level of field expertise cannot explain all of the variance observed. Future work will improve the validity of the findings by using larger corpora of student and published texts.

Four decades of music therapy behavioral research designs: a content analysis of Journal of music therapy articles.  

Science.gov (United States)

This article updates previous content analyses of the Journal of Music Therapy (JMT) and presents information regarding the behavioral research approach to music therapy as reflected by published studies. JMT articles from 1964 through 1999 were examined to determine if the methodology included a behavioral research design (e.g., reversal, multiple baseline). Case studies not meeting the design criteria were excluded from the sample as were experimental group studies using a behavioral observation method or behavioral technique within a traditional statistical design. Experimental studies, however, in which behavioral research designs were included in treatment conditions and assigned to different groups were included. Articles meeting the behavioral research design criteria were analyzed to determine the type of design, the behavioral observation method and reliability report, the client population, and the music application. Of the 607 articles published in JMT, 96 or 15.8% included a behavioral research design. The lowest percentage occurred in the earliest volumes of JMT during the latter part of the 60s. An increase in behavioral research articles occurred during the 70s and 80s and continued throughout the 90s. Other findings include the following: (a) the most prevalent design was the reversal (ABA) with many variations; (b) the predominant observation methods were frequency counts and interval recording with an increase in observation reliability reports in the 80s and 90s; (c) studies published during the 80s and 90s included a wide variety of client populations compared to the 60s and 70s predominant applications with mental retardation and emotional disturbances; (d) the contingent application of music was highest during the 70s and 80s and virtually nonexistent during the 60s and 90s when other treatment conditions employed music as noncontingent background stimulus, an activity for structuring responses, and a cue for maintaining nonmusic responses. The increase in articles through the decades coupled with the increased diversity of populations suggests that behavioral research designs are flexible and applicable in music therapy practice today as much as they were during the initial phase during the 70s and 80s.

e-Research in the Social Sciences: The Possibilities and the Reality (A Review Article  

Directory of Open Access Journals (Sweden)

Full Text Available The purpose of this review is to examine the current status as well as benefits and barriers to online research in the social sciences. With the rapid development of internet technology in the past decade, there has been growing interest in the application of on-line technologies to social science research. While there are a number of on-line sites for survey completion and centralized data sets for studying psychological, health, political and sociological issues, collaborative on-line research communities have not developed at the same pace as these other innovations. The few exploratory studies of e-research collaboration conducted to date suggest that while there are potential benefits, there are a number of social, ethical and professional barriers to its development in the social sciences. A recent curricular innovation, in which undergraduate students from different institutions work collaboratively on an on-line research project, suggests that with specific training, a number of these obstacles can be overcome. However, at this point, there appears to be more potential for collaborative online research than is being realized. Issues such as trust, ownership, and quality assurance will need to be addressed before collaborative on-line research in social science becomes a common practice.

The History and Current Status of Otter Research within Canada based on Peer Reviewed Journal Articles  

Directory of Open Access Journals (Sweden)

Full Text Available In Canada, there are two species of otters, the river otter (Lontra canadensis and the sea otter (Enhydra lutris. The river otter is considered to be plentiful and ranges throughout a large part of Canada. On the other hand, the sea otter is classified as of Special Concern and only small translocated colonies are found along the coastline of Vancouver Island and British Columbia. The scientific literature was reviewed with respect to both river and sea otter research performed within Canada since 1970 to evaluate the number and topics of research papers that had been published dealing with these otter species. Since 1970, 25 papers have been published, most of the research concentrating on contaminants (mercury, organochlorines in river otters (80%. There is only 1 scientific paper (1978 dealing with the sea otter (4%. Almost half of publications studying river otters were from or in combination from the province of Ontario (48%. Miscellaneous topics made up 16% of the publications. This paper reveals that in Canada very little scientific work has been published dealing with sea otters and that a huge number of the publications deal with river otters found within the province of Ontario. Thus since 1970, there has been a serious lack of research dealing with either otter species and that most of that work has had no structure or focus. It is hoped that government agencies, the scientific community, non government organizations, and interested groups can organize strategies and granting opportunities to increase the amount of scientific studies to further understand and protect future populations of these 2 species in Canada.

In the end of nineteen century, phenomenology is born as a philosophical-methodological option for research, in which Comprehensive Sociology, from Alfred Schütz, outstands. This study’s objective is discuss some of the possible contributions from Schütz’s Phenomenological Sociology for nursing research. The main concepts boarded were intentionality, intersubjectivity, determined biographical situation, human actions, typification and social relation. Phenomenological research seeks the meanings that people attribute to their own experience, which are revealed with these people’s descriptions. Alfred Scütz’s phenomenological sociology aims the subjective meaning of the human actions, trying to establish the ideal type by typification. These concepts can be used as a theoretical-methodological base to investigate about things lived in the social world, mainly when it is about a social world in which nursing professionals are part of.

Contributions from Alfred Schütz’s phenomenological sociology for nursing research - review article  

Directory of Open Access Journals (Sweden)

Full Text Available Understanding the human being is a complex task, because it involves biological, psychological and social questions. Investigation of Cartesian procedure had suffered ruptures, mainly because of the criticism to objectivity, on dealing whit human questions. In the end of nineteen century, phenomenology is born as a philosophical-methodological option for research, in which Comprehensive Sociology, from Alfred Schütz, outstands. This study’s objective is discuss some of the possible contributions from Schütz’s Phenomenological Sociology for nursing research. The main concepts boarded were intentionality, intersubjectivity, determined biographical situation, human actions, typification and social relation. Phenomenological research seeks the meanings that people attribute to their own experience, which are revealed with these people’s descriptions. Alfred Scütz’s phenomenological sociology aims the subjective meaning of the human actions, trying to establish the ideal type by typification. These concepts can be used as a theoretical-methodological base to investigate about things lived in the social world, mainly when it is about a social world in which nursing professionals are part of.

Smooth muscle contamination analysis in clinical oncology gene expression research.  

Science.gov (United States)

Gene expression profiling is one of the most explored methods for studying cancers and microarray data repositories have become a rich and important resource. The most common human cancers develop in organs that are walled by smooth muscles. The only method of sample extraction free of unintentional contamination with surrounding tissue is microdissection. Nevertheless, such an approach is implemented infrequently. In the light of the above, there is a possibility of smooth muscle contamination in a large portion of publicly available data. In this study, 2292 publicly available microarrays were analysed to develop a simple screening method for detecting smooth muscle contamination. Microarray Inspector software was used to perform the tests since it has the unique ability to use many selected genes and probesets in a single group as a tissue definition. Furthermore, the test was dataset-independent. Two strategies of tissue definition were explored and compared. The first one depended on Tissue Specific Genes Database (TiSGeD) and BioGPS web resources, which themselves were based on meta-analysis of thousands of microarrays. The second method was based on a differential gene expression analysis of a few hundred preselected arrays. The comparison of the two methods proved the latter to be superior. Among the tested samples of undefined contamination, nearly half were identified to possibly contain significant smooth muscle traces. The obtained results equip researches with a simple method of examining microarray data for smooth muscle contamination. The presented work serves as an example of how to create definitions when searching for other possible contaminations. PMID:24936521

Research article: Watershed management councils and scientific models: Using diffusion literature to explain adoption  

Science.gov (United States)

Recent literature on the diffusion of innovations concentrates either specifically on public adoption of policy, where social or environmental conditions are the dependent variables for adoption, or on private adoption of an innovation, where emphasis is placed on the characteristics of the innovation itself. This article uses both the policy diffusion literature and the diffusion of innovation literature to assess watershed management councils' decisions to adopt, or not adopt, scientific models. Watershed management councils are a relevant case study because they possess both public and private attributes. We report on a survey of councils in the United States that was conducted to determine the criteria used when selecting scientific models for studying watershed conditions. We found that specific variables from each body of literature play a role in explaining the choice to adopt scientific models by these quasi-public organizations. The diffusion of innovation literature contributes to an understanding of how organizations select models by confirming the importance of a model's ability to provide better data. Variables from the policy diffusion literature showed that watershed management councils that employ consultants are more likely to use scientific models. We found a gap between those who create scientific models and those who use these models. We recommend shrinking this gap through more communication between these actors and advancing the need for developers to provide more technical assistance.

Do open access working papers attract more citations compared to printed journal articles from the same research unit?  

DEFF Research Database (Denmark)

This paper presents the results of an empirical case study of the characteristics of citations received by 10 open accessible non-peer reviewed working papers published by a prestigious multidisciplinary, but basically social science research institute, compared to 10 printed peer reviewed journal articles published in the same year (2004) by the same institute and predominantly by the same authors. The study analyzes the total amount of citations and citation impact observed in Web of Science (WoS) and Google Scholar (GS) received during the five-year period 2004-09 (February) by the two publication types, the citation distributions over the individual sample publications and observed years as well as over external, institutional and personal self-citations. The institute concerned is the Danish Institute for International Studies (DIIS), Copenhagen. The results demonstrate that the open access working papers publicly accessible through the DIIS e-archive became far less cited than the corresponding sample of DIIS journal articles published in printed form. However, highly cited working papers have higher impact than the average of the lower half of cited articles. Citation time series show identical distinct patterns for the articles in WoS and GS and working papers in GS, more than doubling the amount of citations received through the latter source.

Research of Emotion Recognition Based on Speech and Facial Expression  

Directory of Open Access Journals (Sweden)

Full Text Available The paper introduced the present status of speech emotion recognition. In order to improve the single-mode emotion recognition rate, the bimodal fusion method based on speech and facial expression was proposed. The emotional databases of Chinese speech and facial expressions were established with the noise stimulus and movies evoking subjects' emtion. On the foundation, we analyzed the acoustic features of Chinese speech signals under different emotional states, and obtained the general laws of prosodic feature parameters. We discussed the single-mode speech emotion recognitions based on the prosodic features and the geometric features of facial expression. Then, the bimodal emotion recognition was obtained by the use of Gaussian Mixture Model. The experimental results showed that, the bimodal emotion recognition rate combined with facial expression was about 6% higher than the single-model recognition rate merely using prosodic features.

FACSGen 2.0 animation software: generating three-dimensional FACS-valid facial expressions for emotion research.  

Science.gov (United States)

In this article, we present FACSGen 2.0, new animation software for creating static and dynamic three-dimensional facial expressions on the basis of the Facial Action Coding System (FACS). FACSGen permits total control over the action units (AUs), which can be animated at all levels of intensity and applied alone or in combination to an infinite number of faces. In two studies, we tested the validity of the software for the AU appearance defined in the FACS manual and the conveyed emotionality of FACSGen expressions. In Experiment 1, four FACS-certified coders evaluated the complete set of 35 single AUs and 54 AU combinations for AU presence or absence, appearance quality, intensity, and asymmetry. In Experiment 2, lay participants performed a recognition task on emotional expressions created with FACSGen software and rated the similarity of expressions displayed by human and FACSGen faces. Results showed good to excellent classification levels for all AUs by the four FACS coders, suggesting that the AUs are valid exemplars of FACS specifications. Lay participants' recognition rates for nine emotions were high, and comparisons of human and FACSGen expressions were very similar. The findings demonstrate the effectiveness of the software in producing reliable and emotionally valid expressions, and suggest its application in numerous scientific areas, including perception, emotion, and clinical and neuroscience research.

Estudio diacrónico de la evaluación en las introducciones de artículos científicos de medicina / Diachronic study of evaluation on introductions of Medicine research articles  

Scientific Electronic Library Online (English)

Full Text Available SciELO Chile | Language: Spanish Abstract in spanish En este artículo se presenta un análisis diacrónico realizado en una muestra de artículos científicos del dominio de la medicina con el fin de determinar la variación en el tiempo de los recursos empleados para expresar la evaluación. Esta incluye, en un sentido amplio, la expresión de la actitud, e [...] l punto de vista o los sentimientos del hablante con respecto a las proposiciones o entidades de las que habla. La actitud se relaciona con la certeza, la obligación o cualquier sistema de valores. Incluye el afecto, el juicio y la apreciación, y los valores pueden ser positivos o negativos. A través del análisis de un corpus constituido por veinte artículos publicados en la revista Medicina (diez de 1940-1941 y diez de 2002-2003), determinamos que la ‘evaluación’ se lleva a cabo fundamentalmente por medio de recursos léxicos y, en particular, mediante cuantificadores. También poseen un rasgo evaluativo ciertos verbos, como ‘apreciar’ o ‘preferir’, y los verbos de medida, como ‘aumentar’ o ‘disminuir’, que indican una valoración vinculada al contexto. Entre ambos grupos de textos se observan diferencias en los esquemas de evaluación: en los de la primera etapa predominan las estructuras de obligación y la presencia del agente evaluador. Los de la segunda etapa, en cambio, muestran una menor evaluación explícita y baja presencia de los autores en el texto. Abstract in english This article reports a diachronic study carried out on a sample of medicine research articles in order to determine variations in evaluation resources. The attitude relates to certainty, obligation and other sets of values. It includes affect, judgement and appreciation and the evaluation can be pos [...] itive or negative. Based on the analysis of twenty research articles of a medical journal, Medicina, (ten from 1941-1942, and ten from 2002-2003) the analysis shows that lexical items, specially quantifiers, are typically used to evaluate. Verbs as ‘appreciate’, ‘prefer’, are evaluative, like ‘increase’, ‘reduce’, which express evaluation related to the context. We have observed differences between the texts of the first group and the texts of the second one. In particular, the first group shows an important number of verbs of obligation, as well as the presence of the agent, responsible of the evaluation. The second group of texts shows lesser explicit evaluation and display strategies for hiding the author of the text.

A cross-disciplinary and cross-cultural study of directives in discussions and conclusions of research articles  

Directory of Open Access Journals (Sweden)

Full Text Available The current study provided cross-cultural and cross-disciplinary analyses of the distribution of directives in discussion and conclusion sections of English and Persian research articles (RAs in disciplines of physics, chemistry, counseling, and sociology, representing hard and soft sciences, respectively. To that aim, 80 RAs from both English and Persian journals between 2000 and 2012 were selected. The RAs were textually analyzed to determine the distribution of directives. Findings revealed a significant difference between Persian hard and soft science RAs in the employment of directives, with soft science writers employing directives more frequently in discussion and conclusion sections in comparison with hard science writers. However, no significant difference was found in the distribution of directives across discussion and conclusion sections of English soft and hard RAs. Moreover, findings did not show a significant difference across Persian and English RAs. Overall, results suggest that Persian and English academic writers tend to follow a similar generic and discursive trend in the employment of directives in their discussion and conclusion sections pointing to the universal nature of directives as persuasive strategies employed by academic writers in canonical branches of science. The findings of the present study might raise learners' awareness of the conventions and lexico-grammatical features of academic writing in Persian and/or English RAs.

A Contrastive Study on Transitional Markers in English Language Teaching Research Articles Written by English and Persian Academic Writers  

Directory of Open Access Journals (Sweden)

Full Text Available The present study attempted to work on the distributions of the Transitional Markers in a corpus of thirty articles related to the discipline of English Language Teaching. All of the articles are written in English, fifteen by academic writers who are native speakers of English and the other fifteen by Persian academic writers. Using descriptive statistics, it was revealed that the Transitional Markers belonging to the categories of contrast and purpose were more used by native writers and Transitional Markers belonging to the category of comparison & similarity were used almost equally by both groups of writers. Transitional Markers belonging to the categories of addition, time, result, place, example and summary & emphasis were more used in the ELT articles written by Persian article writers. Moreover, using inferential statistics, it was indicated that a significant difference exist between the uses of the Transitional Markers in the two groups of the articles.

Conducting Research on the International Space Station using the EXPRESS Rack Facilities. Sean W. Thompson and Robert E. Lake. NASA Marshall Space Flight Center, Huntsville, AL, USA. Eight "Expedite the Processing of Experiments to Space Station" (EXPRESS) Rack facilities are located within the International Space Station (ISS) laboratories to provide standard resources and interfaces for the simultaneous and independent operation of multiple experiments within each rack. Each EXPRESS Rack provides eight Middeck Locker Equivalent locations and two drawer locations for powered experiment equipment, also referred to as sub-rack payloads. Payload developers may provide their own structure to occupy the equivalent volume of one, two, or four lockers as a single unit. Resources provided for each location include power (28 Vdc, 0-500 W), command and data handling (Ethernet, RS-422, 5 Vdc discrete, +/- 5 Vdc analog), video (NTSC/RS 170A), and air cooling (0-200 W). Each rack also provides water cooling (500 W) for two locations, one vacuum exhaust interface, and one gaseous nitrogen interface. Standard interfacing cables and hoses are provided on-orbit. One laptop computer is provided with each rack to control the rack and to accommodate payload application software. Four of the racks are equipped with the Active Rack Isolation System to reduce vibration between the ISS and the rack. EXPRESS Racks are operated by the Payload Operations Integration Center at Marshall Space Flight Center and the sub-rack experiments are operated remotely by the investigating organization. Payload Integration Managers serve as a focal to assist organizations developing payloads for an EXPRESS Rack. NASA provides EXPRESS Rack simulator software for payload developers to checkout payload command and data handling at the development site before integrating the payload with the EXPRESS Functional Checkout Unit for an end-to-end test before flight.

How many orthopedic surgeons does it take to write a research article? 50 years of authorship proliferation in and internationalization of the orthopedic surgery literature.  

Science.gov (United States)

Publications are considered to indicate academic achievement and can lead to various rewards, including job opportunities and research funding. Recent years have seen a rising trend in the number of articles published, multiple authorship, and internationalization of the biomedical literature. The goal of this study was to analyze the trends in authorship over the past 50 years to determine whether the orthopedic literature parallels trends seen in other areas of the biomedical literature. We performed an observational study with analysis of the number of authors and geographic origin of articles published in the Journal of Bone and Joint Surgery British Volume (JBJS) and Clinical Orthopaedics and Related Research (CORR). We analyzed 2776 articles (CORR, n=1809; JBJS, n=967) published between 1958 and 2008 at 10-year intervals. There has been a significant increase in the mean number of authors per article from 1.638 to 4.08 (P<.0001) and 1.633 to 4.540 (P<.0001) for CORR and JBJS, respectively between 1958 and 2008. There has been a significant increase in the international contribution to both journals (P<.0001). The number of countries contributing to articles increased from 5 to 39 and from 17 to 33 for CORR and JBJS, respectively. These findings are similar to other areas of the biomedical literature. The reasons for this proliferation are multifactorial, including multicenter trials and inappropriate authorship. Guidelines for authorship and preparation of manuscripts from the International Committee of Medical Journal Editors or from individual journals are widely available, and every effort should be made to adhere to them to prevent inappropriate authorship proliferation in the future.

Descubriendo algunos problemas en la redacción de Artículos de Investigación Científica (AIC de alumnos de postgrado Discovering some problems in graduate students' composition of research articles  

Directory of Open Access Journals (Sweden)

Full Text Available Hoy en día, la divulgación de la ciencia en la forma de Artículos de Investigación Científica (AIC en revistas indexadas ha dejado de ser una opción y se ha transformado en una necesidad para quien se inicia o ejerce la investigación. A pesar de ello, la formación de investigadores en Chile es reciente y quienes emprenden estudios de postgrado rara vez reciben instrucción formal en la escritura de AIC, menos aún en el conocimiento de los mecanismos de evaluación y de las potenciales revistas donde enviar sus trabajos. En este contexto, el objetivo de este artículo es describir y clasificar una serie de errores que se identifican en los AIC de un grupo de sujetos, estudiantes de postgrado de la Universidad de La Serena, que participaron en una intervención, cuyo propósito fue el aprendizaje de la producción de este género científico especializado. La intervención, en forma de talleres, consistió en 20 sesiones de tres horas cada una, espaciadas por un lapso de una semana. Durante su desarrollo, los sujetos escribieron, editaron en conjunto, y reescribieron las partes estructurales de un artículo de investigación. Los resultados muestran que los sujetos presentan dos grandes tipos de errores: uno asociados a problemas generales de la escritura y otro vinculados más específicamente con la escritura del género en cuestión.Nowadays, the dissemination of science by means of research articles in indexed journals is no longer an option, and it has turned into a necessity for those who are beginning or are devoted to research. However, researcher training in Chile is just beginning, and those who pursue graduate studies seldom receive formal instruction on the writing of scientific research articles (SRA, on a peer review system, or on the prospective journals to which they might submit their manuscripts. Considering the above, the objective of this article is to describe and classify a series of errors detected in the composition of SRAs written by a group of Universidad de La Serena graduate students who participated in an intervention, the purpose of which was to look at how they produce this specialized scientific genre. The intervention took place in 20 three-hour weekly workshop sessions, where the participants wrote, edited collectively, and re-wrote the structural parts of a research article. It was found that the participants' compositions contain general writing errors and genre-specific errors.

Suitability of commonly used housekeeping genes in gene expression studies for space radiation research  

Science.gov (United States)

Research on the effects of ionizing radiation exposure involves the use of real-time reverse transcription polymerase chain reaction (qRT-PCR) for measuring changes in gene expression. Several variables need to be controlled for gene expression analysis, such as different amounts of starting material between the samples, variations in enzymatic efficiencies of the reverse transcription step, and differences in RNA integrity. Normalization of the obtained data to an invariant endogenous control gene (reference gene) is the elementary step in relative quantification strategy. There is a strong correlation between the quality of the normalized data and the stability of the reference gene itself. This is especially relevant when the samples have been obtained after exposure to radiation qualities inducing different amounts and kinds of damage, leading to effects on cell cycle delays or even on cell cycle blocks. In order to determine suitable reference genes as internal controls in qRT-PCR assays after exposure to ionizing radiation, we studied the gene expression levels of nine commonly used reference genes which are constitutively expressed in A549 lung cancer cells. Expression levels obtained for ACTB, B2M, GAPDH, PBGD, 18S rRNA, G6PDH, HPRT, UBC, TFRC and SDHA were determined after exposure to 2 and 6 Gy X-radiation. Gene expression data for Growth arrest and damage-inducible gene 45 (GADD45?) and Cyclin-dependent kinase inhibitor 1A (CDKN1A/p21CIP1) were selected to elucidate the influence of normalization by using appropriate and inappropriate internal control genes. According to these results, we strongly recommend the use of a panel of reference genes instead of only one.

A genética/epidemiologia molecular foi o assunto mais estudado nos artigos de revistas internacionais, na sua maioria abordando mecanismos/etiologia/factores de risco (n=55, 89%). A maior parte (81%) dos artigos publicados em revistas internacionais são de grupos de investigação do Porto, sendo também os mais citados (número mediano de citações até 2004 = 15). Conclusão: A publicação da investigação em cancro do estômago em revistas nacionais ou internacionais depende do objecto de estudo. A alta proporção de artigos no campo da genética contrasta com o reduzido número de publicações acerca do papel etiológico de exposições decorrentes dos estilos de vida. Abstract in english Background: Gastric cancer remains one of the most frequent worldwide, though it may become a neglected disease concerning the research efforts due to its lower frequency in the developed countries. Japan is responsible for most of the stomach cancer research all over the world, with an increasing t [...] rend in the study of genetic susceptibility and the use of molecular markers. Portugal, like Japan, presents one of the highest incidence and mortality rates in the developed world, and our aim was to characterize articles addressing gastric adenocarcinoma or the respective precancerous lesions published by Portuguese researchers, according to the study subjects and authors’ affiliation. Methods: MEDLINE® and Portuguese Medical Journals Index databases were searched within the period 1992-2003 and the abstracts of the identified articles were reviewed. We obtained the number of citations for articles published in international journals through the Web of Science®. Those not reporting original research and those based exclusively in the study of cell lines or animal experimentation, were excluded. Results: We identified 88 articles in international journals (70% addressed cancer mechanisms/etiology/risk factors) and 53 in national journals (87% reported therapy/clinical and pathological descriptions). Genetic/ molecular topics were the most studied in articles on cancer mechanisms/etiology/risk factors from international journals (n=55, 89%). Most articles (81%) published in international journals come from groups from Porto, and these were also the most cited (median number of citations until 2004 = 15). Conclusion: The study scope is a major determinant for publication of stomach cancer research by Portuguese authors in national or international journals. The high proportion of studies on genetics/molecular biology is in contrast with th

Suitability of Commonly Used Housekeeping Genes in Gene Expression Studies for Space Radiation Research  

Science.gov (United States)

Research on the effects of ionizing radiation exposure involves the use of real-time reverse transcription polymerase chain reaction qRT-PCR for measuring changes in gene expression Several variables needs to be controlled for gene expression analysis -- different amounts of starting material between the samples variations in enzymatic efficiencies of the reverse transcription step and differences in RNA integrity Normalization of the obtained data to an invariant endogenous control gene reference gene is the elementary step in relative quantification strategy There is a strong correlation between the quality of the normalized data and the stability of the reference gene itself This is especially relevant when the samples have been obtained after exposure to radiation qualities inducing different amounts and kinds of damage leading to a cell cycle delay or even to a cell cycle block In order to determine suitable reference genes as internal controls in qRT-PCR assays after exposure to ionizing radiation we studied the gene expression levels of commonly used reference genes in A549 lung cancer cells Expression levels obtained for human beta actin ACTB human beta-2-microglobulin B2M human glyceraldehyde-3-phosphate dehydrogenase GAPDH human porphobilinogen deaminase PBGD human 18S ribosomal RNA 18S rRNA human glucose-6-phosphate dehydrogenase G6PDH human hypoxanthine phosphoribosyl transferase HPRT human ubiquitin C UBC human transferrin TFRC

[Research advances on ADAM28 expression and ADAM28-mediated tumor metastasis].  

Science.gov (United States)

A disintegrin-metalloproteinase 28 (ADAM28) is one of important members of ADAM family, that is involved in various biological events including cell adhesion, proteolysis, growth and metastasis of solid tumors and hematological malignancies. Studies have shown that ADAM28 is highly expressed in several human tumors, such as lung, breast and bladder cancers, and chronic lymphocytic leukemia, and its tissue expression levels correlate with cancer metastasis. ADAM28-mediated cancer cell metastasis may be related with the cleavage of von Willebrand's factor (vWF), insulin-like growth factor binding protein-3 (IGFBP-3) and connective tissue growth factor (CTGF), as well as the promoting PSGL-1/P-selectin-mediated cell adhesion. This review summarizes the basic and translational aspects of ADAM28 biology that might stimulate the interest in ADAM28 research and discovery of novel ADAM28 targets, providing potential novel therapies for metastatic cancers.

Investigating Frequency and Distribution of Transition Markers in English and Persian Research Articles in Applied Linguistics: Focusing on Their Introduction Sections  

Directory of Open Access Journals (Sweden)

Full Text Available The pressure to produce work in English and to publish internationally has increased over recent years. However, a large number of non-native writers may be excluded from the web of global scholarship due to defective rhetorical organizations and discourse structures of their works. This study aimed to investigate frequency and distribution of transition markers (TMs in introduction sections of applied linguistics research articles (RAs written by native writers of English (NE, non- native Persian writers of English (NNE, and native writers of Persian (NP. For this purpose, 45 RAs were functionally and manually analyzed and compared to find possible differences among their introduction sections in terms of frequency and distribution of TMs. The results showed that compared with English, Persian language makes more use of TMs. Moreover, it was revealed that NNE writers show a pattern of overuse of TMs when they write in English owing to the effects of their native language writing culture.

ClinData Express--a metadata driven clinical research data management system for secondary use of clinical data.  

Science.gov (United States)

Aim to ease the secondary use of clinical data in clinical research, we introduce a metadata driven web-based clinical data management system named ClinData Express. ClinData Express is made up of two parts: 1) m-designer, a standalone software for metadata definition; 2) a web based data warehouse system for data management. With ClinData Express, what the researchers need to do is to define the metadata and data model in the m-designer. The web interface for data collection and specific database for data storage will be automatically generated. The standards used in the system and the data export modular make sure of the data reuse. The system has been tested on seven disease-data collection in Chinese and one form from dbGap. The flexibility of system makes its great potential usage in clinical research. The system is available at http://code.google.com/p/clindataexpress. PMID:23304327

Heterogeneity research in muscle-invasive bladder cancer based on differential protein expression analysis.  

Science.gov (United States)

The aim of this study was to study the expression profiles of muscle-invasive bladder cancer (MIBC) cells of different risk groups and to explore the crucial role of biological pathway change in heterogeneity of MIBC cells. Thirty individual samples (cancer and non-cancerous specimens) were obtained from patients with MIBC. Laser capture microdissection was employed to harvest the homogeneous MIBC cells and normal urothelial cells. iTRAQ and 2D-LC-MS/MS were used to quantify and identify the differently expressed proteins. Then, the significantly changed proteins were further analyzed using Arraytrack ™ software. The interested proteins were compared with the published literatures to discuss the exact functions. A total of 3,073 non-redundant proteins were identified in this research; therefore, 855/2,210/633 (fold change >1.5 relative to normal group) presented in high-/median-/low-risk groups, respectively. 617/1,620/463 proteins with SWISS-ACC number output from Arraytrack ™ software and presented in high-/median-/low-risk groups, respectively. Pathway analysis revealed that the mainly changed pathways (top-10, p pathways. The mainly altered pathways in Metabolism category included glycolysis/gluconeogenesis, pentose phosphate, pyruvate metabolism pathway for high-risk group, and glutathione metabolism, citrate cycle, oxidative phosphorylation pathways for median-risk group. The major changed pathways for low-risk group included focal adhesion pathway and ECM-receptor interaction pathway. The changed biological pathways are closely related to the regulation of heterogeneity for MIBC. The KEGG pathways of Genetic information processing category and Metabolism (anaerobic or aerobic) category play a crucial role in determining the malignant phenotype of MIBC cells. The quantification analysis of proteins combining with the KEGG pathway analysis contributes to screening candidate biomarkers and guides the biological molecular therapy of MIBC. PMID:25085780

QUANTITATIVE RESEARCH IN FINANCE: AN ANALYSIS OF STATISTICS TECHNIQUES USED BY ARTICLES PUBLISHED IN QUALIFIED SCIENTIFIC JOURNALS FROM 2007 TO 2009  

Directory of Open Access Journals (Sweden)

Full Text Available This study aimed to examine whether there are differences, in terms of sophistication and accuracy, in statistical techniques used by finance articles published in journals classified by CAPES, from 2007 to 2009. The sample consisted of 100 articles from 40 journals, national and international, inserted between strata A1 and B5. We used descriptive statistics in order to characterize the sample, and the chi-square test of independence, by means of which was examined the degree of independence between variables. The results suggest that the higher the classification level of the stratum, the greater the sophistication of statistical techniques employed in the articles. However, regarding the accuracy in applying the techniques, there were no significant differences between one stratum and another. Most of the articles analyzed (57% not validated or partially validated the assumptions required for their use. Thus, it was realized that there was not proper concern with this aspect, even in well qualified strata. We emphasize that the results are restricted to the sample used. We recommend that future studies use large samples, including other means of publication, like events, both in finance as in other areas of knowledge.

Full Text Available SciELO Chile | Language: Spanish Abstract in spanish [...] Abstract in english Background: Financial relationships between the industry and researchers have raised concerns about the existence of conflicts of interest that could influence the scientific validity of the studies. Aim: To determine the financial sources of research articles published in the Revista Médica de Chil [...] e during a five-year period. Material and Methods: Retrospective analysis of all articles classified as “research articles”, published in this journal between years 2001-2005, identifying the funding source and the existence of a declaration of conflicts of interest by the authors. Results: Two hundred seventeen out of 519 research articles published in the period (42%) had an explicit financial source disclosed. Of these, 28% were funded by internal sources, 36% by Fondo Nacional de Desarrollo Científico y Tecnológico and 36% by other sources. Twenty-six studies (5%) received funding from the industry. In only five of these, the authors explicity declared the absence of conflict of interest. Among the studies that did not disclose any financial source, one third required some funding to be carried out. Conclusions: Forty two percent of research articles published in the last five years did not specify the financial source. Those that did specify a funding source were mainly supported by non-profit agencies including university centers and governmental funds. This is in contrast with international reports that evidence an important financial support from the industry. Only a minority of the authors sponsored by the industry declared absence of conflict of interest

Research Resource: Comprehensive Expression Atlas of the Fibroblast Growth Factor System in Adult Mouse  

Science.gov (United States)

Although members of the fibroblast growth factor (FGF) family and their receptors have well-established roles in embryogenesis, their contributions to adult physiology remain relatively unexplored. Here, we use real-time quantitative PCR to determine the mRNA expression patterns of all 22 FGFs, the seven principal FGF receptors (FGFRs), and the three members of the Klotho family of coreceptors in 39 different mouse tissues. Unsupervised hierarchical cluster analysis of the mRNA expression data reveals that most FGFs and FGFRs fall into two groups the expression of which is enriched in either the central nervous system or reproductive and gastrointestinal tissues. Interestingly, the FGFs that can act as endocrine hormones, including FGF15/19, FGF21, and FGF23, cluster in a third group that does not include any FGFRs, underscoring their roles in signaling between tissues. We further show that the most recently identified Klotho family member, Lactase-like, is highly and selectively expressed in brown adipose tissue and eye and can function as an additional coreceptor for FGF19. This FGF atlas provides an important resource for guiding future studies to elucidate the physiological functions of FGFs in adult animals. PMID:20667984

End points and trial design in geriatric oncology research: a joint European organisation for research and treatment of cancer--Alliance for Clinical Trials in Oncology--International Society Of Geriatric Oncology position article.  

Science.gov (United States)

Selecting the most appropriate end points for clinical trials is important to assess the value of new treatment strategies. Well-established end points for clinical research exist in oncology but may not be as relevant to the older cancer population because of competing risks of death and potentially increased impact of therapy on global functioning and quality of life. This article discusses specific clinical end points and their advantages and disadvantages for older individuals. Randomized or single-arm phase II trials can provide insight into the range of efficacy and toxicity in older populations but ideally need to be confirmed in phase III trials, which are unfortunately often hindered by the severe heterogeneity of the older cancer population, difficulties with selection bias depending on inclusion criteria, physician perception, and barriers in willingness to participate. All clinical trials in oncology should be without an upper age limit to allow entry of eligible older adults. In settings where so-called standard therapy is not feasible, specific trials for older patients with cancer might be required, integrating meaningful measures of outcome. Not all questions can be answered in randomized clinical trials, and large observational cohort studies or registries within the community setting should be established (preferably in parallel to randomized trials) so that treatment patterns across different settings can be compared with impact on outcome. Obligatory integration of a comparable form of geriatric assessment is recommended in future studies, and regulatory organizations such as the European Medicines Agency and US Food and Drug Administration should require adequate collection of data on efficacy and toxicity of new drugs in fit and frail elderly subpopulations.

Contudo, essas métricas apresentam limitações na avaliação do potencial de impacto das publicações de um pesquisador, especialmente dentre aqueles mais produtivos. OBJETIVO: Propor e demonstrar a utilização de uma nova métrica científica - índice-H dos artigos citantes, que permite refinar a discriminação do impacto das publicações de pesquisadores experientes sobre o conhecimento existente em sua área. MÉTODOS: Foram analisados dados da Web of Science de 13 dentre os pesquisadores doutores brasileiros mais produtivos na área de exercício físico e esporte, incluindo: número de artigos publicados, número de citações, número médio de citações por artigos, índice-H e o índice-H dos artigos citantes, ou seja, o índice-H obtido a partir da ordenação decrescente dos artigos que citaram artigos publicados pelo pesquisador. Dados de quatro outros pesquisadores - brasileiros e estrangeiros - foram usados como marcos de referência para comparações. RESULTADOS: Os índice-H do pesquisador e o dos artigos citantes são associados (r = 0,92; p > 0,01, porém, quando são analisados os seis pesquisadores mais produtivos, com índices-H acima de 7, a associação entre os dois índices-H desaparece (r = 0,35; p = 0,49. CONCLUSÃO: O índice-H dos artigos citantes pode contribuir para diferenciar a produção científica de pesquisadores com um grande número de artigos publicados.

Therefore, the most important measurements used are the number of citations, the average number of citations per article published in indexed journals and the H-index. Those bibliometric indicators present, however, limitations when assessing the potential impact of the publications of a given researcher, particularly among the most productive ones. OBJECTIVE: To propose and to demonstrate the use of a new scienciometric strategy - the H-index of the citing articles-, that allow to better discriminate the impact of a given researcher to the body of knowledge in the respective research area. METHODS: Research data - Web of Science - from 13 of the most productive Brazilian PhD researchers in the field of exercise and sport sciences were analyzed, including: number of publications, number of citations, average number of citations per article, H-index and the proposed H-index of citing articles (the H-index extracted from the ranking of articles that cited the papers published by a given researcher. Data from four other researchers - Brazilian and foreign - were used as reference for comparisons. RESULTS: The researcher's H-index and the H-index of the citing articles were associated (r=.92; p>.01. However, when the six most productive authors were analyzed with H-index above 7, the association between the two indexes disappears (r=.35; p=.49. CONCLUSIONS: The H-index of the citing articles can be useful to discriminate the scientific production of authors with a high number of published papers. It is suggested that this algorithm should be adopted by Brazilian and foreign financing and scientific production evaluation agencies.

METHODS: Research data - Web of Science - from 13 of the most productive Brazilian PhD researchers in the field of exercise and sport sciences were analyzed, including: number of publications, number of citations, average number of citations per article, H-index and the proposed H-index of citing articles (the H-index extracted from the ranking of articles that cited the papers published by a given researcher). Data from four other researchers - Brazilian and foreign - were used as reference for comparisons. RESULTS: The researcher's H-index and the H-index of the citing articles were associated (r=.92; p>.01). However, when the six most productive authors were analyzed with H-index above 7, the association between the two indexes disappears (r=.35; p=.49). CONCLUSIONS: The H-index of the citing articles can be useful to discriminate the scientific production of authors with a high number of published papers. It is suggested that this algorithm should be adopted by Brazilian and foreign financing and scientific production evaluation agencies.

Scientific Electronic Library Online (English)

Full Text Available SciELO Brazil | Language: Portuguese Abstract in portuguese INTRODUÇÃO: Há um crescente interesse e necessidade em avaliar a qualidade da produção científica dos pesquisadores. Para tal, as métricas mais importantes são: número de citações, número médio de citações por artigo indexado e o índice-H. Contudo, essas métricas apresentam limitações na avaliação d [...] o potencial de impacto das publicações de um pesquisador, especialmente dentre aqueles mais produtivos. OBJETIVO: Propor e demonstrar a utilização de uma nova métrica científica - índice-H dos artigos citantes, que permite refinar a discriminação do impacto das publicações de pesquisadores experientes sobre o conhecimento existente em sua área. MÉTODOS: Foram analisados dados da Web of Science de 13 dentre os pesquisadores doutores brasileiros mais produtivos na área de exercício físico e esporte, incluindo: número de artigos publicados, número de citações, número médio de citações por artigos, índice-H e o índice-H dos artigos citantes, ou seja, o índice-H obtido a partir da ordenação decrescente dos artigos que citaram artigos publicados pelo pesquisador. Dados de quatro outros pesquisadores - brasileiros e estrangeiros - foram usados como marcos de referência para comparações. RESULTADOS: Os índice-H do pesquisador e o dos artigos citantes são associados (r = 0,92; p > 0,01), porém, quando são analisados os seis pesquisadores mais produtivos, com índices-H acima de 7, a associação entre os dois índices-H desaparece (r = 0,35; p = 0,49). CONCLUSÃO: O índice-H dos artigos citantes pode contribuir para diferenciar a produção científica de pesquisadores com um grande número de artigos publicados. Sugere-se a adoção de sua mensuração pelas agências brasileiras e estrangeiras de fomento e de avaliação da produção científica.

Too Few Articles in the Journal Literature on Instruction in Academic Libraries are Research?Based. A review of: Crawford, Gregory A., and Jessica Feldt. “An Analysis of the Literature on Instruction in Academic Libraries.” Reference & User Services Quarterly 46.3 (Spr. 2007: 77?87.  

Directory of Open Access Journals (Sweden)

Full Text Available Objective – To discover which journals publish a preponderance of the literature on instruction in academic libraries, and to further learn what topics are discussed in the literature and what methods of inquiry are used to explore those topics.Design – Comparative analysis.Setting – The ERIC database.Subjects – Journal articles published between 1971 and 2002, found in the ERIC database via the descriptor ‘library instruction.’Methods – Journal articles published between 1971 and 2002 were searched in the ERIC database using the term ‘library instruction,’ because the term has been used by ERIC since the inception of the database. Article characteristics such as year of publication, journal in which a given article was published, and types of articles were identified. After normalizing the identification of article types by comparing individual codifications of a random sample of articles from the results list, the researchers coded all of the articles according to the articles’ main topics. These article topics were then condensed into broader topics (e.g. articles coded initially as addressing the topics of instruction to “graduate students” or “high school students” were condensed under the heading “instruction of specific populations”. Those articles deemed to have a research component were further analyzed in terms of research methodology, scope, and use of statistics. The questions guiding the authors? study consisted of:• In which journals are articles on instruction in academic libraries published?• What are the topics of the articles that have been published?• How has the literature of instruction in academic libraries changed over the years?• What is the nature of research [authors? emphasis] articles on instruction in academic libraries?• For research articles, what are the research methods used and what types of statistics are utilized? (77?78.Main results – The search found 791 articles appearing in 90 journals. However, only six journals were responsible for publishing 60% of the articles on the results list. Based on the categorization into topics or types,five article types – “general essays,” articles on “instruction for searching online catalogs and databases,” “articles on course? or assignment?related instruction,” “programmatic and management issues,”and “specific institution instruction” –accounted for 54% of the total articles; eleven other topics are represented in the remaining articles. Only 24.5% of the articles could be considered “research?based.” While nine types of research methods were used, 62.3% of the research?based articles relied on surveys or questionnaires. However, taking into account what could be an expected decline in interest for studying instruction for microforms, and an increased interest in studying instruction for the Internet, the types of articles published each year between 1971 and 2002 remained generally static.Conclusion – The authors conclude that, unsurprisingly, a select few journals are responsible for publishing the majority of articles on instruction in academic libraries, and note that these journals are “closely associated with academic librarianship and instruction” (85. The authors’ findings concerning the types of articles published over the course of the date range examined, although interesting, are equally unsurprising. What is surprising and alarming, is that only a quarter of all articles published are research-based. Furthermore, those articles that were found to be research-based did not often employ sophisticated research methods, preferring for example, the use of descriptive statistics over inferential statistics. Ideally, this article will spur the development and publication of more, and more rigorous, research?based scholarship in addition to pointing authors both to the journals most likely to publish their research and to the topics that have been historically (since 1971 underrepresented in the literature.

The Development in Leading e-Government Articles 2001-2010: Definitions, Perspectives, Scope, Research Philosophies, Methods and Recommendations: An Update of Heeks and Bailur  

DEFF Research Database (Denmark)

This paper presents a study of development in leading e-government papers from 2001-2010. Inspired by a study by Heeks and Bailur, the analysis uses a different sampling method, adds new themes, and focuses on changes over time. Through an iterative process known as template analysis the five most cited papers from each year are analyzed according to themes such as perspectives on the impact and impact causes of e-government, methods used, underlying research philosophies and recommendations. Findings indicate that the papers are still somewhat optimistic regarding the impact of e-government, but no longer as technologically deterministic. Discussions of research philosophies start to appear, as do social constructionist studies, although most papers are still positivistic. There is an increase in the use of primary data, and some movement in focus from infrastructure and services towards citizens. There is little development in the discussions of generalization of results and recom-mendations offered.

Rhythm Analysis by Heartbeat Classification in the Electrocardiogram (Review article of the research achievements of the members of the Centre of Biomedical Engineering, Bulgarian Academy of Sciences  

Directory of Open Access Journals (Sweden)

Full Text Available The morphological and rhythm analysis of the electrocardiogram (ECG is based on ventricular beats detection, wave parameters measurement, as amplitudes, widths, polarities, intervals and relations between them, and a subsequent classification supporting the diagnostic process. Number of algorithms for detection and classification of the QRS complexes have been developed by researchers in the Centre of Biomedical Engineering - Bulgarian Academy of Sciences, and are reviewed in this material. Combined criteria have been introduced dealing with the QRS areas and amplitudes, the waveshapes evaluated by steep slopes and sharp peaks, vectorcardiographic (VCG loop descriptors, RR intervals irregularities. Algorithms have been designed for application on a single ECG lead, a synthesized lead derived by multichannel synchronous recordings, or simultaneous multilead analysis. Some approaches are based on templates matching, cross-correlation or rely on a continuous updating of adaptive thresholds. Various beat classification methods have been designed involving discriminant analysis, the K-th nearest neighbors, fuzzy sets, genetic algorithms, neural networks, etc. The efficiency of the developed methods has been assessed using internationally recognized arrhythmia ECG databases with annotated beats and rhythm disturbances. In general, high values for specificity and sensitivity competitive to those reported in the literature have been achieved.

El discurso científico de la historia: Análisis estructural y retórico de los artículos de investigación en historia / THE SCIENTIFIC DISCOURSE OF HISTORY: A STRUCTURAL AND RHETORICAL ANALYSIS OF HISTORY RESEARCH ARTICLES  

Scientific Electronic Library Online (English)

Full Text Available SciELO Chile | Language: Spanish Abstract in spanish Al igual que en cualquier otra disciplina científica, el discurso general de la historia se transmite a través de distintos géneros, siendo el artículo de investigación (en adelante, AI), una manifestación que permite, en particular, analizar el discurso científico de la historia. En esta materia, e [...] l trabajo de Swales (1990, 2004) y su teoría de Movidas Retóricas (en adelante, MR) es un referente para el estudio específico de los artículos de investigación. Los estudios que siguen esta teoría son, en su mayoría, aplicables a trabajos escritos en la lengua inglesa y dan cuenta, de manera aislada, de las distintas secciones superestructurales, tales como la introducción o la conclusión. En este contexto, el objetivo de la presente investigación es describir, estructural y retóricamente, los artículos de investigación en historia. Para este efecto, se realizó un análisis de todas las secciones superestructurales presentes en los AiI de nuestro corpus. Además, se identificaron las MR prototípicas de los AI en historia, y se estableció el grado de similitud de las secciones superestructurales del corpus con los de otras disciplinas. Los resultados principales señalan que los artículos de investigación de historia se caracterizan, principalmente, por la narración e interpretación de hechos, en conjunto con la referencia literal a otras fuentes. Abstract in english As in all scientific disciplines, the general discourse of history is conveyed by means of different discourse genres. One of such genres is the research article (RA), which therefore enables the analysis of the scientific discourse of history. In this respect, the descriptive work of Swales (1990, [...] 2004) and his theory of Rhetorical Moves (RM) is seminal to the study of scientific research articles. The studies based on this theory have been published mostly in English and involve the analysis of some of the distinctive super-structural sections, mainly the introduction and the conclusion, in a discrete approach. The aim of the present study is to describe, both structurally and rhetorically, research articles in the area of history written in Chilean Spanish. To this end, an analysis was carried out of the superstructures present in the RA's of our corpus. Additionally, the prototypical RM's in history RA's were identified and the degree of similarity between these super-structural sections in our corpus and those of other disciplines was established. The main results of this study demonstrate that research articles in the area of history are characterized, mainly, by the narration and interpretation of facts, together with the literal reference to other sources.

The closterovirus-derived gene expression and RNA interference vectors as tools for research and plant biotechnology  

Directory of Open Access Journals (Sweden)

Full Text Available Important progress in understanding replication, interactions with host plants, and evolution of closteroviruses enabled engineering of several vectors for gene expression and virus-induced gene silencing (VIGS. Due to the broad host range of closteroviruses, these vectors expanded vector applicability to include important woody plants such as citrus and grapevine. Furthermore, large closterovirus genomes offer genetic capacity and stability unrivaled by other plant viral vectors. These features provided immense opportunities for using closterovirus vectors for the functional genomics studies and pathogen control in economically valuable crops. This review briefly summarizes advances in closterovirus research during the last decade, explores the relationships between virus biology and vector design, and outlines the most promising directions for future application of closterovirus vectors.

Tracking Theory Building and Use Trends in Selected LIS Journals: More Research is Needed. A review of: Kim, Sung?Jin, and Dong Y. Jeong. “An Analysis of the Development and Use of Theory in Library and Information Science Research Articles.” Library & Information Science Research 28.4 (Sept. 2006: 548?62.  

Directory of Open Access Journals (Sweden)

Full Text Available Objective ? The authors measure theory incidents occurring in four LIS journals between 1984?2003 in order to examine their number and quality and to analyze them by topic. A third objective, only identified later in the text of the study, was to compare theory development and use between Korean and international journals. Research questions asked include whether LIS has its own theoretical base as a discipline, and what characteristics the theoretical framework has.Design – Bibliometric study.Setting – Journal issues selected from four LIS journals for the time span from 1984 ? 2003.Subjects – Two international journals, Journal of the American Society for Information Science and Technology (JASIST and Library and Information Science Research (LISR were selected based on their high ranking in the Social Sciences Citation Index (SSCI impact factors. Two Korean journals, Journal of the Korean Society for Information Management (JKSIM and Journal of the Korean Society for Library and Information Science (JKSLIS were selected.Methods ? After having determined a definition of theory, and identifying different levels of theory, the authors set up rules for the identification of theory incidents, which are defined as “events in which the author contributed to the development or the use of theory in his/her own paper” (550. Content analysis of 1661 research articles was performed to measure theory incidents according to working definitions. Interrater reliability was ensured by conducting independent coding for “subfield classification, identification of theory incidents, and quality measurement” (555,using a sample of 199 articles (random selection not specified, achieving 94?97% interrater reliability. Incidents, once identified, were evaluated for quality using Dubin’s “efficiency of law” criteria, involving measures of relatedness, directionality, co?variation, rate of change, and “profundity,” defined as the depth to which theory is incorporated into the research study.Main Results ? 21.79% (n=362 of the articles contained theory incidents that were analyzed and evaluated. Trend measurement indicated an overall increase, although a slight decrease was shown in the year range 1993?2003. International journals accounted for 61.33% of theory incidents, compared to 38.67% for the Korean journals. T?testing showed that differences in means between Korean and international journals were not statistically significant. Topical theory areas were ranked by frequency. The top five areas were shown to be nearly identical between Korean and international journals. ANOVA was performed with significant results in the difference between efficiency ratings. Conclusion – The authors find that the overall proportion of theory incidents including both theory development and use increased through the 20?year time span examined, and that LIS has established its own theoretical framework based upon the frequency of incidents.

EXPRESS--Examining Pediatric Resuscitation Education Using Simulation and Scripting. The birth of an international pediatric simulation research collaborative--from concept to reality.  

Science.gov (United States)

Over the past decade, medical simulation has evolved into an essential component of pediatric resuscitation education and team training. Evidence to support its value as an adjunct to traditional methods of education is expanding; however, large multicenter studies are very rare. Simulation-based researchers currently face many challenges related to small sample sizes, poor generalizability, and paucity of clinically proven and relevant outcome measures. The Examining Pediatric Resuscitation Education Using Simulation and Scripting (EXPRESS) pediatric simulation research collaborative was formed in an attempt to directly address and overcome these challenges. The primary mission of the EXPRESS collaborative is to improve the delivery of medical care to critically ill children by answering important research questions pertaining to pediatric resuscitation and education and is focused on using simulation either as a key intervention of interest or as the outcome measurement tool. Going forward, the collaborative aims to expand its membership internationally and collectively identify pediatric resuscitation and simulation-based research priorities and use these to guide future projects. Ultimately, we hope that with innovative and high-quality research, the EXPRESS pediatric simulation research collaborative will help to build momentum for simulation-based research on an international level.

Various kinds offacial expressions are present in human face which can be identified based on their geometric features,appearance features and hybrid features . The two basic concepts of extracting features are based onfacial deformation and facial motion. This article also identifies the techniques based on thecharacteristics of expressions and classifies the suitable methods that can be implemented.

Pilot research of the expression of MMP-2 gene and survivin gene in primary esophageal cancer and subclinical microscopic tumor  

International Nuclear Information System (INIS)

wo genes increased significantly along with tumor stage or tumor length, and there was statistical correlation between the length of tumor and the positive expression ranges of Survivin gene. Conclusions: Both MMP-2 gene and Survivin gene are positively expressed in esophageal cancerous peripheral tissue. The range positively expressing the two genes is < 70 mm in more than 96% of the samples, and the length is correlated with the tumor stage. More attention should be paid to the peripheral differentiated normal tissue with positive expression of MMP-2 gene and Survivin gene in esophageal squamous carcinoma. (authors)

Directory of Open Access Journals (Sweden)

Full Text Available The production of proteins in appropriate quantity and quality is an essential requirement of the present time. There appears to be a progressive increase in the application of mammalian cells for proteins production. Expression systems utilizing mammalian cells for recombinant proteins are able to introduce proper protein folding, post-translational modifications, and product assembly, which are important for complete biological activity. This review article is totally based on literature survey. In this article much emphasis has been done on the mammalian expression system. The author focused on different mammalian cell lines that express the gene. The different vector systems that transfer the gene into mammalian cells like plasmid based expression vectors, adenovirus vectors, vaccinia vectors, retroviral vector and baculovirus as vectors were explored. The processes for the transfer of gene into mammalian cells were also reviewed. Application and limitations of mammalian expression system were also focused. The purpose of research in writing this article is to create awareness in researchers, starting their career in gene expression related to mammalian cells. The principal result and major conclusion of this article is to make available the molecular technologies, expression system and applications of gene expression in mammalian cell lines.

Dense ceramic articles  

International Nuclear Information System (INIS)

A method is described for the manufacture of articles of substantially pure dense ceramic materials, for use in severe environments. Si N is very suitable for use in such environments, but suffers from the disadvantage that it is not amenable to sintering. Some disadvantages of the methods normally used for making articles of Si N are mentioned. The method described comprises mixing a powder of the substantially pure ceramic material with an additive that promotes densification, and which is capable of nuclear transmutation into a gas when exposed to radiation, and hot pressing the mixture to form a billet. The billet is then irradiated to convert the additive into a gas which is held captive in the billet, and it is then subjected to a hot forging operation, during which the captive gas escapes and an article of substantially pure dense ceramic material is forged. The method is intended primarily for use for Si N, but may be applied to other ceramic materials. The additive may be Li or Be or their compounds, to the extent of at least 5 ppm and not more than 5% by weight. Irradiation is effected by proton or neutron bombardment. (UK)

Citation advantage of open access articles.  

Science.gov (United States)

Open access (OA) to the research literature has the potential to accelerate recognition and dissemination of research findings, but its actual effects are controversial. This was a longitudinal bibliometric analysis of a cohort of OA and non-OA articles published between June 8, 2004, and December 20, 2004, in the same journal (PNAS: Proceedings of the National Academy of Sciences). Article characteristics were extracted, and citation data were compared between the two groups at three different points in time: at "quasi-baseline" (December 2004, 0-6 mo after publication), in April 2005 (4-10 mo after publication), and in October 2005 (10-16 mo after publication). Potentially confounding variables, including number of authors, authors' lifetime publication count and impact, submission track, country of corresponding author, funding organization, and discipline, were adjusted for in logistic and linear multiple regression models. A total of 1,492 original research articles were analyzed: 212 (14.2% of all articles) were OA articles paid by the author, and 1,280 (85.8%) were non-OA articles. In April 2005 (mean 206 d after publication), 627 (49.0%) of the non-OA articles versus 78 (36.8%) of the OA articles were not cited (relative risk = 1.3 [95% Confidence Interval: 1.1-1.6]; p = 0.001). 6 mo later (mean 288 d after publication), non-OA articles were still more likely to be uncited (non-OA: 172 [13.6%], OA: 11 [5.2%]; relative risk = 2.6 [1.4-4.7]; p 2.0]; Z = 3.123; p = 0.002; October 2005: 6.4 [SD = 10.4] versus 4.5 [SD = 4.9]; Z = 4.058; p libraries, OA articles are more immediately recognized and cited by peers than non-OA articles published in the same journal. OA is likely to benefit science by accelerating dissemination and uptake of research findings. PMID:16683865

As sales force represents for most organizations their “spearheds”and direct contact with the market, its management can be a source for customer satisfaction and overall efficiency. Relationship marketing research with all its particularities and dimensions, if tailored appropriately can explicitly pinpoint major sources of customer satisfaction and dissatisfaction. Focus of contemporary relationship marketing is the customer viewed across lifetime as a profit source and partner rather than on short term for singular transactions. Research findings help the organization better manage its sales force and generate customer satisfaction, retention and loyalty and maximize profits while achieving superior efficiency.

Quality of scientific articles  

Directory of Open Access Journals (Sweden)

Full Text Available The paper discusses the difficulties in judging the quality of scientific manuscripts and describes some common pitfalls that should be avoided when preparing a paper for submission to a peer-reviewed journal. Peer review is an imperfect system, with less than optimal reliability and uncertain validity. However, as it is likely that it will remain as the principal process of screening papers for publication, authors should avoid some common mistakes when preparing a report based on empirical findings of human research. Among these are: excessively long abstracts, extensive use of abbreviations, failure to report results of parsimonious data analyses, and misinterpretation of statistical associations identified in observational studies as causal. Another common problem in many manuscripts is their excessive length, which makes them more difficult to be evaluated or read by the intended readers, if published. The evaluation of papers after their publication with a view towards their inclusion in a systematic review is also discussed. The limitations of the impact factor as a criterion to judge the quality of a paper are reviewed.

Research agendas.  

Science.gov (United States)

WHILE EACH ARTICLE IN THIS ISSUE OF JERHRE raises important questions that call for empirical research, one article-the editorial-subsumes all issues raised by the rest of the articles herein. It is a call to make full use of the allowed freedom to design an improved system of ethical problem solving and ethical oversight in human research. Being an ethical researcher is often cast in terms of compliance with ethics committee rules. In some contexts those rules, inflexibly applied, may cause unnecessary delay, damage and hindrance to important research projects. Stated otherwise, they may impose unethical requirements on research. Yet it is the very inaction or compliance of researchers and research administrators that causes us to fail to help create systems of research oversight that work-that foster valid and ethical research and advance human society.

Differential gene expression in C4 plants. Research proposal, February 1, 1982-January 31, 1983. [Pea plants  

Energy Technology Data Exchange (ETDEWEB)

The topic of this research proposal is slightly different from that originally outlined. Specifically, instead of characterizing the genes encoding the small subunit of RuBP carboxylase and the chlorophyll a/b binding polypeptide from corn, these genes from pea are being characterized. The above polypeptides represent the major products of cytoplasmic protein synthesis in green leaves. CDNA clones encoding the above polypeptides were isolated and characterized. Both of these cDNA clones have now been sequenced, providing the amino acid sequences for the carboxylase small subunit and, for the first time, for the chlorophyll a/b binding polypeptide. Pea nuclear DNA was cloned into the lambda phage Charon 4, and cloned nuclear DNA sequences encoding the above polypeptides were isolated. Future work will be concerned with the structural and functional characterization of these nuclear genes.

How Newspaper-Article-Events, Other Stock Market Indices, and the Foreign Currency Rate Affect the Philippine Stock Market  

Directory of Open Access Journals (Sweden)

Full Text Available Eugene Fama in his “Efficient Market Hypothesis” introduced the term newspaper-article-event. The aim of this paper is to find out if newspaper-article-events which are presented and discussed in newspaper articles and which could collage to create an atmosphere of investment, together with the indices of other stock markets (treated as other events and the performance of the Philippine Peso against the US Dollar (considered as another event could affect the closing Philippine Stock Market Indices (Phisix during the 2004 Election Campaign in the Philippines and the 2005 Impeachment Controversy against the Philippine President Gloria Macapagal-Arroyo. Expressivity rating was conceived to measure the expressivity of newspaper articles and, in turn, represent the degree of positiveness, neutralness or negativeness of newspaper-article-events. This research found significant correlations between the closing Forex rate the day before and the present closing Phisix for the two cases. Significant models were also derived incorporating several types of newspaper articles, other stock market indices and the previous Forex rate for the two cases.

Analysis of the journal articles of medical imaging by bibliometrics  

International Nuclear Information System (INIS)

Purpose: To evaluate the development status, character and trends of medical imaging. Methods: The articles published on >, > and > from 1983 to 1996 were analyzed by bibliometrics and compared with the articles published on > and > of USA. Results: total numbers of the published articles were increasing gradually in these years. But, the rate of increase was not equal among different research fields. For example, the number of research articles of CT, MR and Interventional Radiography were increasing more quickly than that of X ray. It was also found that the development status and trends of medical imaging were different between China and America. Most research articles published in the journals of America in 1996 were about MR, whereas CT ranked first in china in the same year. Conclusion: Medical imaging develops very quickly in recent years. The emphasis of research and development has switched over from traditional X ray to new fields or techniques, such as Ct, MR and interventional radiology

Full Text Available The overall goal of my research is to highlight the social and relational depth of references and citations in scientific evidence that, far from being mere indicators of productivity and visibility of research, are also an expression of scientific sociability. Because they boost the social and intellectual research, references and citations are the possible vector for transformation of scientific community.Based on a corpus of 32 articles from a chemistry laboratory in Toulouse and with interviews with their authors, I analyze the references of three of them as an opportunity for authors, to boost their relations with collectives to whom they claim to belong or they oppose through these references. I continue by showing that the networks of references of each publication are embedded in a universe of references (all citations that references of the article have generated in the SCI-Thomson Reuters, before and after its publication that they partly contribute to create.

Glucose transporters: expression, regulation and cancer  

Directory of Open Access Journals (Sweden)

Full Text Available Mammalian cells depend on glucose as a major substrate for energy production. Glucose is transported into the cell via facilitative glucose transporters (GLUT present in all cell types. Many GLUT isoforms have been described and their expression is cell-specific and subject to hormonal and environmental control. The kinetic properties and substrate specificities of the different isoforms are specifically suited to the energy requirements of the particular cell types. Due to the ubiquitousness of these transporters, their differential expression is involved in various disease states such as diabetes, ischemia and cancer. The majority of cancers and isolated cancer cell lines over-express the GLUT family members which are present in the respective tissue of origin under non-cancerous conditions. Moreover, due to the requirement of energy to feed uncontrolled proliferation, cancer cells often express GLUTs which under normal conditions would not be present in these tissues. This over-expression is predominantly associated with the likelihood of metastasis and hence poor patient prognosis. This article presents a review of the current literature on the regulation and expression of GLUT family members and has compiled clinical and research data on GLUT expression in human cancers and in isolated human cancer cell lines.

Participation of immigrant women family caregivers in qualitative research.  

Science.gov (United States)

The recruitment of articulate, expressive participants is an essential part of methodology in qualitative research. This article presents the authors' experience in the recruitment of immigrant women of Chinese and South Asian origin in an ethnographic study. The study included women caring for an adult or child family member who had a chronic health problem. Knowledge of women family caregivers' health is restricted by the failure to include diverse groups of women in research. In this article, the authors discuss issues related to recruitment and participation of immigrant women in research, including establishing access to diverse groups of women, benefits for immigrant women, and placing the researcher and research process on the same level. Practical research strategies to address these issues and engage the women in research that portrays their perspectives are presented. The authors' discussion concludes with reflection on their experience and that of other researchers. PMID:11569331

Article Impact Means Journal Impact  

Digital Repository Infrastructure Vision for European Research (DRIVER)

These days there is a lot of misunderstanding of scientometrics and we often see a confusion of the research with its indicators. Science ministries and university administrators try to push their country's or institution's "research impact" by telling researchers to increase numeric figures that were invented as proxies for later assessment. In obvious juxtaposition to common sense this even leads to direct orders to postdocs "to only publish in high impact journals" and not to engage in oth...

Energy Technology Data Exchange (ETDEWEB)

The paper described the fiscal 1997 result of the research on the application of local industrial article use reverse engineering (RE, it had been regarded as imitation and reproduction technology, but has recently been as a part of the production information integration). With the actual local industrial article as standard, which has features in design and was added with local traditionality, such as glass having 3D free-form surface, 3D shape information modeling technology RE is developed, and a system for direct automatic metal mold processing is established, aiming at shortening of delivery date, cost reduction and higher grade. The target of the research is Okinawa prefecture. In fiscal 1997, study was made of the speeding-up of the non-contact 3D shape information inputting (multi-point simultaneous inputting by CCD of the laser reflected light of the actual model) and the data storage technology. Cast iron was selected as molding materials, judging from reactivity/machinability with heat resistant glass. Also studied was the blend of glass materials suitable for press forming. Further, studies were proceeded with of development of intellectual cutting tools into which sensor function is integrated and of virtual reality for facilitating/accelerating the design up to metal mold manufacturing. 39 refs., 88 figs., 21 tabs.

Ordinary Expression and Musical Expressiveness  

Directory of Open Access Journals (Sweden)

Full Text Available A general assumption embedded in different approaches to musical expressiveness has been to accept that ordinary expression is the paradigm or the reference phenomenon for explaining other forms of (artistic expression and in particular musical expressiveness. This has led to an attempt to find a relationship between ordinary expression and musical expressiveness that can account for why we find expressive features or content in things such as symphonies, sonatas and other forms of musical composition. In this paper I argue for the idea that musical expressiveness does not necessarily have to be understood in terms of, or by drawing an analogy to, ordinary expression. Rather, I will try, first, to defend the idea that musical expressiveness could be conceived on a continuum with ordinary expression. Secondly, I will try to show that this understanding of musical expressiveness can make more sense of the way in which some features of musical expressiveness may pass on ordinary expressiveness and enrich its repertoire.

Research 101: demystifying nursing research.  

Science.gov (United States)

As home health nurses begin to more fully embrace evidence-based practice, we need to be reading research articles in addition to those being published in Home Healthcare Nurse. Many of us have been out of school for several years or have never studied nursing research, and the terminology can be daunting. Evidence-based practice strengthens our ability to provide nursing care based upon the best scientific and researched information. The evidence gleaned from research demonstrates best practice methods rather than those we have traditionally used with little or no scientific basis. The purpose of this article is to provide new knowledge or dust the cobwebs from our past studies of nursing research. A review of the types of research, as well as its language, can help home health nurses be consumers of research with greater understanding. Use of the Internet and ways to access nursing research will be discussed. This article is a brief overview only and more in-depth principles can be accessed by one of the many nursing research resources. PMID:19907241

The Role of Documentation in Practice-Led Research  

Directory of Open Access Journals (Sweden)

Full Text Available Practice-led research in the field of art and design usually involves a study of the interplay between a researcher-practitioner and her artistic work in process. This article seeks to illustrate that documentation of art practice can be a means to record that interplay and it can be used as relevant material in practice-led research. The article will present an account of documentation in practice-led research highlighting two principal aspects: phases of documentation and the role of documentation within the overall research process. The account will capture reflections of the author’s own practice-led research in fiber art, which investigates the relationship between materials and artistic expression, in the context of contemporary art.

Automated identification of biomedical article type using support Vector machines  

Science.gov (United States)

Authors of short papers such as letters or editorials often express complementary opinions, and sometimes contradictory ones, on related work in previously published articles. The MEDLINE® citations for such short papers are required to list bibliographic data on these "commented on" articles in a "CON" field. The challenge is to automatically identify the CON articles referred to by the author of the short paper (called "Comment-in" or CIN paper). Our approach is to use support vector machines (SVM) to first classify a paper as either a CIN or a regular full-length article (which is exempt from this requirement), and then to extract from the CIN paper the bibliographic data of the CON articles. A solution to the first part of the problem, identifying CIN articles, is addressed here. We implement and compare the performance of two types of SVM, one with a linear kernel function and the other with a radial basis kernel function (RBF). Input feature vectors for the SVMs are created by combining four types of features based on statistics of words in the article title, words that suggest the article type (letter, correspondence, editorial), size of body text, and cue phrases. Experiments conducted on a set of online biomedical articles show that the SVM with a linear kernel function yields a significantly lower false negative error rate than the one with an RBF. Our experiments also show that the SVM with a linear kernel function achieves a significantly higher level of accuracy, and lower false positive and false negative error rates by using input feature vectors created by combining all four types of features rather than any single type.

Impact of estrogen receptor (ER) and human epidermal growth factor receptor-2 (HER2) co-expression on breast cancer disease characteristics: implications for tumor biology and research.  

Science.gov (United States)

ER and HER2 are critical drivers of breast cancer biology and can interact when co-expressed, but less data describe the impact of ER/HER2 co-expression on clinical disease characteristics. We studied the impact of ER and HER2 (co)-expression in a cohort of 1,187 patients with invasive breast cancer and compared disease characteristics among different groups according to ER and HER2 status. Age, tumor size, grade, nodal status, TNM stage, and metastatic sites were compared and significance determined using the appropriate t tests. All p values were two-tailed. Compared to ER-negative/HER2-negative disease as the control group, ER expression was associated with older age, smaller tumors, lower grade, earlier TNM stage, and increased bone involvement in de novo metastasis, while HER2 had no significant impact on these characteristics. ER and HER2 co-expression was associated with lower grade and higher bone involvement in de novo metastasis, reflecting a retained impact for ER. HER2 impact on ER-positive disease was reflected by younger age, higher grade and TNM stage, and increased frequency of visceral involvement in de novo metastasis. Within the ER-positive/HER2-positive group, triple positive breast cancer (ER+/PgR+/HER2+) was associated with younger age compared to ER+/PgR-/HER2+ disease (mean age of 50.8 vs. 56 years, p = 0.0226). PgR was also associated with younger age in ER+/HER2- disease with a mean age of 57.6 years in ER+/PgR+/HER2- disease vs. 63.4 years in ER+/PgR-/HER2- disease (p < 0.0001). In conclusion, ER has a profound impact on breast cancer characteristics, including a retained impact when co-expressed with HER2. Similarly, HER2 dramatically modulates ER-positive breast cancer making it more aggressive. PgR association with young age may be related to hormonal levels of the premenopausal state, with HER2 providing an earlier growth advantage in triple positive disease, suggesting a specific dependence for this subset on high estrogen levels.

Emotional Expression in Reality TV  

DEFF Research Database (Denmark)

Reality TV has been disputed and discussed along many lines for the last 20 years; the media themselves always with a twist of concern about reality programs crossing moral borderlines while research has put more interest in questions of genre and representation of more or less useful and maybe empowering social identities. In the latest generation of reality TV which Misha Kava has described as the “celebrity generation”, it seems that reality creates new standards for mixing facts and fiction and even different “realities” as participants become media stars while more traditional celebrities are being treated as ordinary people. My article will discuss different presentations of selves and especially the emotional verbal and nonverbal expressions in reality TV communication. Aspects of the intimate self and its emotional expressions seem to be strategically managed in reality TV and even commodified in the celebrity culture. The article will discuss and analyze examples of reality TV’s interpersonal strategically communication in relation to ordinary interpersonal communication where much information about the self is communicated incidentally to the purpose of the situation, and some is communicated involuntarily. Goffman has described the intended and the unintended aspects of personal communication as information ‘given’ which means intended and managed, and information ‘given off’ which is unintentional. In relation to his investigation in human lying and deceit Ekman points out, that information ‘given off’ in lying behavior will must often be found in non-verbal mikro expressions and mikro gestures. I will end by discussing the strategic emotional expressions as production of floating identities in a broader framework on the basis of among others Gergen, Lipovetsky and Baumann. These postmodern and hyperreal trends will then be discussed in relation to Danish philosopher Løgstrup and his concept of the basic utterances of life (de suveræne livsytringer) and Habermas’ understanding of life/system worlds. I aim to get closer to an understanding of what management of visibility and sensibility in communication might mean to the human being of our time – and why we seem to seek it so desperately in the (media) culture.

Finding and Recommending Scholarly Articles  

Science.gov (United States)

The rate at which scholarly literature is being produced has been increasing at approximately 3.5 percent per year for decades. This means that during a typical 40 year career the amount of new literature produced each year increases by a factor of four. The methods scholars use to discover relevant literature must change. Just like everybody else involved in information discovery, scholars are confronted with information overload. Two decades ago, this discovery process essentially consisted of paging through abstract books, talking to colleagues and librarians, and browsing journals. A time-consuming process, which could even be longer if material had to be shipped from elsewhere. Now much of this discovery process is mediated by online scholarly information systems. All these systems are relatively new, and all are still changing. They all share a common goal: to provide their users with access to the literature relevant to their specific needs. To achieve this each system responds to actions by the user by displaying articles which the system judges relevant to the user's current needs. Recently search systems which use particularly sophisticated methodologies to recommend a few specific papers to the user have been called "recommender systems". These methods are in line with the current use of the term "recommender system" in computer science. We do not adopt this definition, rather we view systems like these as components in a larger whole, which is presented by the scholarly information systems themselves. In what follows we view the recommender system as an aspect of the entire information system; one which combines the massive memory capacities of the machine with the cognitive abilities of the human user to achieve a human-machine synergy.

Collaboration range: Effects of geographical proximity on article impact  

Science.gov (United States)

Spatial scientometrics studies how geography influences knowledge creation. In the recent years there has been a surge in this kind of studies, due to the increase of international collaborations. Most of the work in this field has been focused on the geographical distribution of researchers, whilst few have considered how proximity between coauthors influences research quality. In this work we leverage a dataset of geolocalized articles to assess the effect of geographical distance on article impact. More precisely, the dataset, provided by the Observatory of Science and Technology (O.S.T.), consists of roughly 106 scientific articles, gathering all European articles written in 2000 and 2007, spanning 9 disciplines. We evaluate under which geographical extent coauthorships have higher probability of resulting in high impact articles ("high impact" is here approximated by "being in the top 10% most cited articles of its discipline"). We also describe spatial distribution of coauthorship, delineating geographical areas where the production is proportionally higher. The distribution is evaluated both in term of km (as the crow flies), and in terms of administrative partitions (authors' cities, regions, countries).

 Prokaryotic expression systems  

Directory of Open Access Journals (Sweden)

Full Text Available For overproduction of recombinant proteins both eukaryotic and prokaryotic expression systems are used. Choosing the right system depends, among other things, on the growth rate and culture of host cells, level of the target gene expression and posttranslational processing of the synthesized protein. Regardless of the type of expression system, its basic elements are the vector and the expression host.The most widely used system for protein overproduction, both on a laboratory and industrial scale, is the prokaryotic system. This system is based primarily on the bacteria E. coli, although increasingly often Bacillus species are used. The prokaryotic system allows one to obtain large quantities of recombinant proteins in a short time. A simple and inexpensive bacterial cell culture and well-known mechanisms of transcription and translation facilitate the use of these microorganisms. The simplicity of genetic modifications and the availability of many bacterial mutants are additional advantages of the prokaryotic system. In this article we characterize the structural elements of prokaryotic expression vectors. Also strategies for preparation of the target protein gene that increase productivity, facilitate detection and purification of recombinant protein and provide its activity are discussed. Bacterial strains often used as host cells in expression systems as well as the potential location of heterologous proteins are characterized.Knowledge of the basic elements of the prokaryotic expression system allows for production of biologically active proteins in a short time and in satisfactory quantities.

REVIEW ARTICLE: A taste sensor  

Science.gov (United States)

A multichannel taste sensor, namely an electronic tongue, with global selectivity is composed of several kinds of lipid/polymer membranes for transforming information about substances producing taste into electrical signals, which are input to a computer. The sensor output exhibits different patterns for chemical substances which have different taste qualities such as saltiness, sourness and bitterness, whereas it exhibits similar patterns for chemical substances with similar tastes. The sensor responds to the taste itself, as can be understood from the fact that taste interactions such as the suppression effect, which appears for mixtures of sweet and bitter substances, can be reproduced well. The suppression of the bitterness of quinine and a drug substance by sucrose can be quantified. Amino acids can be classified into several groups according to their own tastes on the basis of sensor outputs. The tastes of foodstuffs such as beer, coffee, mineral water, milk, sake, rice, soybean paste and vegetables can be discussed quantitatively using the taste sensor, which provides the objective scale for the human sensory expression. The flavour of a wine is also discriminated using the taste-odour sensory fusion conducted by combining the taste sensor and an odour-sensor array using conducting polymer elements. The taste sensor can also be applied to measurements of water pollution. Miniaturization of the taste sensor using FET produces the same characteristics as those of the above taste sensor by measuring the gate-source voltage. Use of the taste sensor will lead to a new era of food and environmental sciences.

... Unfortunately, several studies have found GC therapy can also produce neuromotor/ cognitive deficits and selectively stunt the cerebellum. However, despite its continued use, relatively little is known about how exposure to this hormone might produce neurodevelopmental deficits. In this review, we use rodent and human research to provide evidence that GC therapy may disrupt cerebellar development through the rapid induction of apoptosis in the cerebellar external ... The EGL is a transient proliferative region responsible for the production of over 90% of the neurons in the cerebellum. During normal development, endogenous GC stimulation is thought to selectively signal the elimination of the EGL once production of new neurons is complete. As a result, GC therapy may precociously eliminate the EGL before it can produce enough neurons for normal cerebellar function. It is hoped that ...

Distribution of Articles in Malaysian Secondary School English Language Textbooks  

Directory of Open Access Journals (Sweden)

Full Text Available This paper reports the results of a corpus-based study on English grammar articles presented in the Malaysian Form 1 to Form 5 English Language textbooks. The study aimed to find out the distribution patterns of the articles and the distributions of their colligation patterns in the secondary school English Language textbooks. The findings showed that all the three articles (a, an, the are presented in all the five English Language textbooks and that their frequency of occurrences has an increasing trend from Form 1 to Form 5. However, the distributions of the colligation patterns of the articles showed inconsistency from one form to another. Some colligation patterns were over-emphasized while others were neglected in the English language textbooks. This study indicates that a textbook corpus can be useful in analyzing the presentation of grammatical structures (articles, in the case of this research. The findings can provide guidance to teachers to improve their pedagogical practices in the teaching of articles and to cater to the weaknesses of the presentation of articles in the textbooks.

THE IMPLEMENTATION OF FINDINGS PUBLISHED IN SCHOLARLY ARTICLES  

Directory of Open Access Journals (Sweden)

Full Text Available Articles published in scholarly journals, such as this one, tend to be mainly addressed to researchers at universities. Industrial follow-up and implementation of results from a scholarly article appears to be the exception, rather than the rule. Research grant specifications, as well as university policies, favor the generation of new knowledge, rather than the implementation of good ideas. But without patent protection, corporations have low motivation to expend the considerable effort to reduce ideas to practice after they have been openly published. The author speculates that the situation could be much more dynamic if there were a system of priority of implementation. According to such a system, the first company to successfully implement an idea that first appears in a peer-reviewed journal article, as validated by its debut in the marketplace, would have a grace period during which competitors would have to pay them a fee to sell a generic version of the same thing.

Animal research  

DEFF Research Database (Denmark)

This article presents the ethical issues in animal research using a combined approach of ethical theory and analysis of scientific findings with bearing on the ethical analysis. The article opens with a general discussion of the moral acceptability of animal use in research. The use of animals in research is analyzed from the viewpoint of three distinct ethical approaches: contractarianism, utilitarianism, and animal rights view. On a contractarian view, research on animals is only an ethical issue to the extent that other humans as parties to the social contract care about how research animals are faring. From the utilitarian perspective, the use of sentient animals in research that may harm them is an ethical issue, but harm done to animals can be balanced by benefit generated for humans and other animals. The animal rights view, when thoroughgoing, is abolitionist as regards the use of animals in science (as in any other human use that is not also in the animals’ best interest). These views are not compatible, and since all three views in more or less pure form are found in modern Western societies, use of animals for research is bound to cause controversy. However, there may be room for some kind of compromise where adherents of each view compromise on some points. The ethical basis for the mainstream view of the use of animals in research is analyzed in this light. In the second part of the article, scientific information about the use of animals in research (and in particular the harm and benefit of such use) is analyzed in the light of ethical questions that seem to be pertinent against the background of a mainstream compromise view.

Transgenic mouse lines expressing rat AH receptor variants - A new animal model for research on AH receptor function and dioxin toxicity mechanisms  

International Nuclear Information System (INIS)

Han/Wistar (Kuopio; H/W) rats are exceptionally resistant to 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) toxicity mainly because of their mutated aryl hydrocarbon receptor (AHR) gene. In H/W rats, altered splicing of the AHR mRNA generates two AHR proteins: deletion (DEL) and insertion (INS) variants, with the INS isoform being predominantly expressed. To gain further insight into their functional properties, cDNAs of these and rat wild-type (rWT) isoform were transferred into C57BL/6J-derived mice by microinjection. The endogenous mouse AHR was eliminated by selective crossing with Ahr-null mice. A single mouse line was obtained for each of the three constructs. The AHR mRNA levels in tissues were generally close to those of C57BL/6 mice in INS and DEL mice and somewhat higher in rWT mice; in testis, however, all 3 constructs exhibited marked overexpression. The transgenic mouse lines were phenotypically normal except for increased testis weight. Induction of drug-metabolizing enzymes by TCDD occurred similarly to that in C57BL/6 mice, but there tended to be a correlation with AHR concentrations, especially in testis. In contrast to C57BL/6 mice, the transgenics did not display any major gender difference in susceptibility to the acute lethality and hepatotoxicity of TCDD; rWT mice were highly sensitive, DEL mice moderately resistant and INS mice highly resistant. Co-expression of mouse AHR and rWT resulted in augmented sensitivity to TCDD and abolished the natural resistance of female C57BL/6 mice, whereas mice co-expressing mouse AHR and INS were resistant. Thus, these transgenic mouse lines provide a novel promising tool for molecular studies on dioxin toxicity and AHR function.

Energy Technology Data Exchange (ETDEWEB)

The effort concerns Ryukyu craftwork articles. Reverse engineering used to be regarded as a technique of imitation or duplication but today it is drawing attention as a concept of positively utilizing the directionality of information flow in the integrated environment. In the development of a reverse information system, novel designs are created by utilizing a 3-dimensional data base, a high-efficiency fabrication technology for metal patterns for the press-molding of glass is established incorporating some fabrication diagnosing techniques, and a system is constructed under which fabrication accuracy is evaluated and difference data are fed back. In the development of technologies for metal pattern cutting and surface reforming, a metal pattern fabrication technology for molding glass, low in cost and high in performance, is systematized, which enables short delivery. In the diversification of glass products, Ryukyu patterns are collected and Ryukyu glass products are tentatively manufactured by press-molding, and a good result is achieved. In the field of total system technology, basic technologies for an advanced and integrated common production base are established. A virtual reality assisted designing system is developed, under which the designer feels force on the finger tips when preparing a shape for a 3-dimensional structure. (NEDO)

STATISTICAL IDENTIFICATION OF RESEARCH TRENDS MANIFESTED IN THE FIELD OF SURVEY INTERVIEWER CHARACTERISTIC’S  

Directory of Open Access Journals (Sweden)

Full Text Available In this paper we intend to identify the research trends manifested in the literature on the survey interviewer characteristic’s. A first objective pursued was to identify the distribution of research topics, their territorial distribution and their dynamics expressed in the study of survey interviewer characteristics. A second objective was to verify if the publication of articles in a journal depends on the theme, on the geographical area from which the author came or on the period of the research. In order to achieve these objectives we used descriptive statistics, multiple correspondence analysis and logistic regression. Using the statistical software R statistical data were processed.For the analyzed sample, the results of statistical analysis showed that a signifi cant number of articles have been published by American and European researchers. Most these articles were published after 2000, and the main research theme is the analysis of the survey interviewer characteristics. The data analysis shows that the moment of publication of the research results in a prestigious journal depends on economic, political, social and cultural context characteristic of geographical area from which the author comes. The results also showed that a certain period when the articles by analyzed sample where published and the geographical area from which the researcher comes had a negative effect on the estimated probability to approach a research topic. Also, articles written by U.S. researchers were more likely to be published.

Measuring the Interestingness of News Articles  

Energy Technology Data Exchange (ETDEWEB)

An explosive growth of online news has taken place. Users are inundated with thousands of news articles, only some of which are interesting. A system to filter out uninteresting articles would aid users that need to read and analyze many articles daily, such as financial analysts and government officials. The most obvious approach for reducing the amount of information overload is to learn keywords of interest for a user (Carreira et al., 2004). Although filtering articles based on keywords removes many irrelevant articles, there are still many uninteresting articles that are highly relevant to keyword searches. A relevant article may not be interesting for various reasons, such as the article's age or if it discusses an event that the user has already read about in other articles. Although it has been shown that collaborative filtering can aid in personalized recommendation systems (Wang et al., 2006), a large number of users is needed. In a limited user environment, such as a small group of analysts monitoring news events, collaborative filtering would be ineffective. The definition of what makes an article interesting--or its 'interestingness'--varies from user to user and is continually evolving, calling for adaptable user personalization. Furthermore, due to the nature of news, most articles are uninteresting since many are similar or report events outside the scope of an individual's concerns. There has been much work in news recommendation systems, but none have yet addressed the question of what makes an article interesting.

Mouse models of mantle cell lymphoma, complex changes in gene expression and phenotype of engrafted MCL cells: implications for preclinical research.  

Science.gov (United States)

Mantle cell lymphoma (MCL) is an aggressive type of B-cell non-Hodgkin lymphoma (NHL) associated with poor prognosis. Animal models of MCL are scarce. We established and characterized various in vivo models of metastatic human MCL by tail vein injection of either primary cells isolated from patients with MCL or established MCL cell lines (Jeko-1, Mino, Rec-1, Hbl-2, and Granta-519) into immunodeficient NOD.Cg-Prkdc(scid) Il2rg(tm1Wjl)/SzJ mice. MCL infiltration was assessed with immunohistochemistry (tissues) and flow cytometry (peripheral blood). Engraftment of primary MCL cells was observed in 7 out of 12 patient samples. The pattern of engraftment of primary MCL cells varied from isolated involvement of the spleen to multiorgan infiltration. On the other hand, tumor engraftment was achieved in all five MCL cell lines used and lymphoma involvement of murine bone marrow, spleen, liver, and brain was observed. Overall survival of xenografted mice ranged from 22 ± 1 to 54 ± 3 days depending on the cell line used. Subsequently, we compared the gene expression profile (GEP) and phenotype of the engrafted MCL cells compared with the original in vitro growing cell lines (controls). We demonstrated that engrafted MCL cells displayed complex changes of GEP, protein expression, and sensitivity to cytotoxic agents when compared with controls. We further demonstrated that our MCL mouse models could be used to test the therapeutic activity of systemic chemotherapy, monoclonal antibodies, or angiogenesis inhibitors. The characterization of MCL murine models is likely to aid in improving our knowledge in the disease biology and to assist scientists in the preclinical and clinical development of novel agents in relapsed/refractory MCL patients.

Challenging of Facial Expressions Classification Systems: Survey, Critical Considerations and Direction of Future Work  

Directory of Open Access Journals (Sweden)

Full Text Available The main purpose of this study is analysis of the parameters and the affects of those on the performance of the facial expressions classification systems. In recent years understanding of emotions is a basic requirement in the development of Human Computer Interaction (HCI systems. Therefore, an HCI is highly depended on accurate understanding of facial expression. Classification module is the main part of facial expressions recognition system. Numerous classification techniques were proposed in the previous researches to use in the facial expressions recognition systems. In order to evaluate the performance of the classification system we should consider the parameters which influence the classification results. Therefore, in this article, the most recent classification techniques for the purpose of facial expressions recognition as well as features extraction were surveyed and the parameters which affect the accuracy of results were considered and discussed. Based on this article, the features type, number of extracted features, database and image type are the main parameters that influence the accuracy rate of classification models. Furthermore, as the direction of the future work of this research, a Genetic-Fuzzy classification model was proposed for facial expressions recognition to fulfill the classification requirements.

Top-Cited Articles in Traumatic Brain Injury  

Science.gov (United States)

A review of the top-cited articles in a scientific discipline can identify areas of research that are well established and those in need of further development, and may, as a result, inform and direct future research efforts. Our objective was to identify and characterize the top-cited articles in traumatic brain injury (TBI). We used publically available software to identify the 50 TBI articles with the most lifetime citations, and the 50 TBI articles with the highest annual citation rates. A total of 73 articles were included in this review, with 27 of the 50 papers with the highest annual citation rates common to the cohort of 50 articles with the most lifetime citations. All papers were categorized by their primary topic or focus, namely: predictor of outcome, pathology/natural history, treatment, guidelines and consensus statements, epidemiology, assessment measures, or experimental model of TBI. The mean year of publication of the articles with the most lifetime citations and highest annual citation rates was 1990?±?14.9?years and 2003?±?6.7?years, respectively. The 50 articles with the most lifetime citations typically studied predictors of outcome (34.0%, 17/50) and were specific to severe TBI (38.0%, 19/50). In contrast, the most common subject of papers with the highest annual citation rates was treatment of brain injury (22.0%, 11/50), and these papers most frequently investigated mild TBI (36.0%, 18/50). These findings suggest an intensified focus on mild TBI, which is perhaps a response to the dedicated attention these injuries are currently receiving in the context of sports and war, and because of their increasing incidence in developing nations. Our findings also indicate increased focus on treatment of TBI, possibly due to the limited efficacy of current interventions for brain injury. This review provides a cross-sectional summary of some of the most influential articles in TBI, and a bibliometric examination of the current status of TBI research. PMID:25414657

Full Text Available SciELO Chile | Language: Spanish Abstract in spanish A partir de una revisión crítica de distintos enfoques que se centran en la descripción de las estructuras retóricas y de sus rasgos lingüísticos en artículos de investigación, en el presente trabajo proponemos un nuevo método para describir este fenómeno en artículos de investigación en español. Pa [...] ra ello, se etiquetó, con movidas retóricas, un corpus de 162 artículos que es representativo de la producción científica chilena entre los años 2000 y 2008. A los 11.000 o más registros derivados del análisis, se aplicó técnicas estadísticas que permiten dar cuenta de cuáles son las movidas retóricas (MR) prototípicas y describir los patrones léxico-gramaticales asociados a ellas en este tipo de textos especializados. Los resultados muestran, en primer lugar, cuáles son las MR prototípicas en este tipo de textos y, en segundo lugar, que a ellas se asocian patrones léxico-gramaticales específicos. Los resultados de esta investigación se constituyen en valiosa evidencia empírica tanto para los interesados en el análisis del discurso científico como para aquellos enfocados en el ámbito de la didáctica y el aprendizaje de la escritura científica. Abstract in english In this paper, we propose a new method for the description of rhetorical structures and their corresponding linguistic features in research articles in Spanish. The method is based on a critical review of different approaches focusing on this phenomenon. To this effect, we labelled a 162-research-ar [...] ticle corpus using rhetorical moves. The corpus is representative of Chilean scientific production between 2000 and 2008. We applied statistical techniques to over the 11,000 records to account for the prototypical rhetorical moves and describe the lexico-grammatical patterns associated to them in this type of specialist texts. The results of the study demonstrate the operation of particular 'prototypical' rhetorical moves in such texts as well as the lexico-grammatical patterns which formalize the former. The research done provides valuable empirical evidence both for those aiming at the analysis of scientific discourse and those focusing on the teaching and learning of scientific writing.

Research in business ethics  

Directory of Open Access Journals (Sweden)

Full Text Available Research in business ethics is vital for the expansion and credibility of this fairly recent academic field. This article argues that there are three factors that are crucially important for research in business ethics. They are (a the ontological assumptions that research in this field is premised upon, (b the choice of research strategies and methodologies and (c the role of theory in research practice. Each of these three factors is explored and pitfalls relating to each of them are identified. The article also suggests guidelines for dealing with each of these factors in business ethics research.

Articles on elderly in Serbian medical journals  

Directory of Open Access Journals (Sweden)

Full Text Available Introduction Population aging is a feature of all countries in the world. According to statistics, the Republic of Serbia is one of the countries with the majority of the elderly. Taking this into account, are articles on the elderly well represented in domestic medical journals? Objective The aim of the paper was to determine whether there was a sufficient number of articles on the elderly in domestic medical journals. Methods The articles on the elderly were searched using search engines in domestic and foreign medical journals for the last 5 years compared with the number of articles on children in the same publications for the same period. Results In the Serbian Citation Index, 11 articles on the topic of the elderly, and 487 on children were registered. In Srpski arhiv za celokupno lekarstvo, there was registered only one article on the topic of the elderly, and 30 on children. In Vojnosanitetski pregled, 2 articles on the elderly and 13 on children were registered (p<0001. For the last five years, in the New England Journal of Medicine, there were 593 articles on the elderly and 759 articles on children; in the JAMA, there were 63 articles on the elderly and 303 articles on children; and in The Lancet, in the last five years, 46 articles on the elderly and 148 articles on children were published. Conclusion The themes of the elderly were rarely represented in Serbian medical journals. This has reduced the interest of physicians in medical problems of this growing population of patients and further sent them away from making standards in the diagnosis and treatment of the elderly.

Predicting Future Citation Count Using Bibliographic and Author Information of Articles  

Directory of Open Access Journals (Sweden)

Full Text Available Electronic journal continues to spread rapidly among academic researchers. Citation count shown of an article in academic journals plays an important role in academia. It helps academic researchers in choosing suitable and reliable references for their research. It is unfortunate that recently published papers tend to be unapparent, since it has less citation count than other former works. This research proposes a new way to predict future citation count of an article using regression analysis by machine learning. As a result, citation count prediction of article is delivered using the new proposed method.

Research by design - a research strategy  

DEFF Research Database (Denmark)

Abstract The idea of an expressive component in research is important to the architectural industry. The expressive element - the possibility of expressing the qualitative aspects of the world and adding something new to the existing through experiments and proposals - is characteristic for the field. All research environments, in the science tradition and in the humanities, have their characteristics. On the one hand, they live up to certain common scientific and methodological criteria - originality and transparency - on the other hand they have different practices, using different methods. Research is ‘coloured’ by traditions and professions, and research in architecture should be coloured too, taking in consideration that the practise of architects stretch from natural science and sociology to art, and because the most important way in which the architect achieves new cognition is through the work with form and space – drawings, models and completed works. Probably all good design is informed by some kind of researchresearch based design. But can research arise from design?

The Bibliometric Properties of Article Readership Information  

Science.gov (United States)

The NASA Astrophysics Data System (ADS), along with astronomy's journals and data centers (a collaboration dubbed URANIA), has developed a distributed on-line digital library which has become the dominant means by which astronomers search, access and read their technical literature. Digital libraries such as the NASA Astrophysics Data System \\citep{2005JASIS.tmp....2K} permit the easy accumulation of a new type of bibliometric measure, the number of electronic accesses (``reads'') of individual articles. We explore various aspects of this new measure. We examine the obsolescence function as measured by actual reads, and show that it can be well fit by the sum of four exponentials with very different time constants. We compare the obsolescence function as measured by readership with the obsolescence function as measured by citations. We find that the citation function is proportional to the sum of two of the components of the readership function. This proves that the normative theory of citation is true in the mean. We further examine in detail the similarities and differences between the citation rate, the readership rate and the total citations for individual articles, and discuss some of the causes. Using the number of reads as a bibliometric measure for individuals, we introduce the read-cite diagram to provide a two-dimensional view of an individual's scientific productivity. We develop a simple model to account for an individual's reads and cites and use it to show that the position of a person in the read-cite diagram is a function of age, innate productivity, and work history. We show the age biases of both reads and cites, and develop two new bibliometric measures which have substantially less age bias than citations: SumProd, a weighted sum of total citations and the readership rate, intended to show the total productivity of an individual; and Read10, the readership rate for papers published in the last ten years, intended to show an individual's current productivity. We also discuss the effect of normalization (dividing by the number of authors on a paper) on these statistics. We apply SumProd and Read10 using new, non-parametric techniques to rank and compare different astronomical research organizations

ORGANIZATIONAL LIFE CYCLE AND MANAGEMENT CONTROL: AN ANALYSIS OF ARTICLES IN INTERNATIONAL JOURNAL OF ACCOUNTING  

Directory of Open Access Journals (Sweden)

Full Text Available The aim of this study is to analyze the papers on the approach of the organizational life cycle at the international level, raising the main issues associated with management controls. In a survey of 67 journals came to an initial sample of 39 articles. After reading the abstracts to identify articles relating to organizational life cycle management controls, the sample was seven articles. The international journal of accounting that most published articles related to organizational life cycle was the Management Accounting Research. The recent publications are two articles in 2005 and three articles in 2008. It is noteworthy that in articles published in 2008, all were authored or co-authored by Hanna Silvola. The small number of studies found that allows the subject may be the subject of further research, contributing organizations, managers and other stakeholders to better understand how these controls are used and change with the evolution of the company.

[Protein expression and purification].  

Science.gov (United States)

Production of recombinant proteins is essential for many applications in both basic research and also in medicine, where recombinant proteins are used as pharmaceuticals. This review summarizes procedures involved in recombinant protein expression and purification, including molecular cloning of target genes into expression vectors, selection of the appropriate expression system, and protein purification techniques. Recombinant DNA technology allows protein engineering to modify protein stability, activity and function or to facilitate protein purification by affinity tag fusions. A wide range of cloning systems enabling fast and effective design of expression vectors is currently available. A first choice of protein expression system is usually the bacteria Escherichia coli. The main advantages of this prokaryotic expression system are low cost and simplicity; on the other hand this system is often unsuitable for production of complex mammalian proteins. Protein expression mediated by eukaryotic cells (yeast, insect and mammalian cells) usually produces properly folded and posttranslationally modified proteins. How-ever, cultivation of insect and, especially, mammalian cells is time consuming and expensive. Affinity tagged recombinant proteins are purified efficiently using affinity chromatography. An affinity tag is a protein or peptide that mediates specific binding to a chromatography column, unbound proteins are removed during a washing step and pure protein is subsequently eluted.

Science.gov (United States)

The Role 3 Medical Treatment Facility (Field Hospital) in Camp Bastion (R3 Bastion) is acknowledged to be one of the busiest dedicated trauma facilities in the world. Casualties typically present with severe injuries and in physiological extremis. These casualties form a unique cohort representing the most relevant population to evaluate the effectiveness of treating battlefield injuries as academic clinicians and scientists interested in trauma seek to improve outcomes for such patients in the future. This article describes four separate but related research projects that have been undertaken in Camp Bastion, Afghanistan, over the last year. They traverse the spectrum of clinical research, ranging from data collection to a randomised control trial. The aim is to discuss some of the problems encountered and the solutions that made it possible to undertake research in a theatre of operations, thereby providing a starting point for others who may wish to initiate research in a similar environment.

A critical review of Dr. Charles S. Greene's article titled "Managing the Care of Patients with Temporomandibular Disorders: a new Guideline for Care" and a revision of the American Association for Dental Research's 1996 policy statement on temporomandibular disorders, approved by the AADR Council in March 2010, published in the Journal of the American Dental Association September 2010.  

Science.gov (United States)

Dr. Charles Greene's article, "Managing the Care of Patients with TMDs A New Guideline for Care," and the American Association for Dental Research's (AADR) 2010 Policy Statement on Temporomandibular Disorders, published in the Journal of the American Dental Association (JADA) September 2010, are reviewed in detail. The concept that all temporomandibular disorders (TMDs) should be lumped into one policy statement for care is inappropriate. TMDs are a collection of disorders that are treated differently, and the concept that TMDs must only be managed within a biopsychosocial model of care is inappropriate. TMDs are usually a musculoskeletal orthopedic disorder, as defined by the AADR. TMD orthopedic care that is peer-reviewed and evidence-based is available and appropriate for some TMDs. Organized dentistry, including the American Dental Association, and mainstream texts on TMDs, support the use of orthopedics in the treatment of some TMDs. TMDs are not psychological or social disorders. Informed consent requires that alternative care is discussed with patients. Standard of care is a legal concept that is usually decided by a court of law and not decided by a policy statement, position paper, guidelines or parameters of care handed down by professional organizations. The 2010 AADR Policy Statement on TMD is not the standard of care in the United States. Whether a patient needs care for a TMD is not decided by a diagnostic test, but by whether the patient has significant pain, dysfunction and/or a negative change in quality of life from a TMD and they want care. Some TMDs need timely invasive and irreversible care. PMID:22435173

Content analysis of published articles in the South African Journal of Economic and Management Sciences  

Scientific Electronic Library Online (English)

Full Text Available SciELO South Africa | Language: English Abstract in english The publication of academic research is important for its contribution to the body of knowledge. A periodic analysis of journal content leads to the identification of research practices; while it also identifies the challenges that researchers face. The South African Journal of Economic and Manageme [...] nt Sciences (SAJEMS) is considered to be one of the leading publications in the field of economic and managerial research in South Africa. The SAJEMS was selected as the unit of analysis; and a content analysis was conducted on 257 articles published during the seven-year period 2004 - 2010. The main purpose of this study was to investigate the input and output factors relating to published articles, including questions on authors and article content, such as the various methodological approaches. The findings revealed that there has been a decrease in co-authored articles during the period 2005 - 2008. Although the contribution by practitioners increased significantly in 2005 and 2008, the majority of the articles are still authored predominantly by academics. It is promising to see that international authors were involved in nearly 20 per cent of the articles contributed. When it came to the methodological approaches, the articles employed largely non-probability sampling designs. Furthermore, almost two-thirds of the articles published in SAJEMS were based on quantitative research designs. This content analysis reveals the current research practices published in the SAJEMS. It provides food for thought for academics.

Physiotherapy for Women with Stress Urinary Incontinence: A Review Article  

Science.gov (United States)

[Purpose] This review article is designed to expose physiotherapists to a physiotherapy assessment of stress urinary incontinence (SUI) and the treatment and possibly preventive roles that they might play for women with SUI. Specifically, the goal of this article is to provide an understanding of pelvic floor muscle function and the implications that this function has for physiotherapy treatment by reviewing articles published in this area. [Methods] A range of databases was searched to identify articles that address physiotherapy for SUI, including the Cochrane Library, Medline, and CINAHL. [Results] According to the articles identified in our databases research, greater improvements in SUI occur when women receive a supervised exercise program of at least three months. The effectiveness of physiotherapy treatment is increased if the exercise program is based on some principles, such as intensity, duration, resembling functional task, and the position in which the exercise for pelvic floor muscles is performed. Biofeedback and electrical stimulation may also be clinically useful and acceptable modalities for some women with SUI. [Conclusion] We concluded that the plan for physiotherapy care should be individualized for each patient and include standard physiotherapy interventions.

Directionally solidified article with weld repair  

Science.gov (United States)

A directionally solidified nickel-base superalloy article has a defect therein extending parallel to the solidification direction. The article is repaired by removing any foreign matter present in the defect, and then heating the article to a repair temperature of from about 60 to about 98 percent of the solidus temperature of the base material in a chamber containing a protective gas that inhibits oxidation of the base material. The defect is filled with a filler metal while maintaining the article at the repair temperature. The filling is accomplished by providing a source of the filler metal of substantially the same composition as the base material of the directionally solidified article, and melting the filler metal into the defect progressively while moving the source of the filler metal relative to the article in a direction parallel to the solidification direction. Optionally, additional artificial heat extraction is accomplished in a heat-flow direction that is within about 45 degrees of the solidification direction, as the filler metal solidifies within the defect. The article may thereafter be heat treated.

Shared Responsibility under Article 80 CISG  

DEFF Research Database (Denmark)

Article 80 exempts from liability in the situation where the promisor's failure to perform has been caused by the promisee. The Article has been insufficiently dealt with in the literature and has been overlooked in case law. The paper demonstrates that article 80 has an independent scope compared to articles 77, 79 and 80. Five areas are investigated in this regard; the placement in CISG, the focus of the Articles, the cause of the detriment or loss, the affected remedies and the duty to overcome the detriment or loss. Further more, the paper outlines the issues related to the particular situation of shared responsibility in which both the promisor and the promisee seem to have caused the promisor's failure to perform. Article 80 applies to three different case types. Firstly, cases of sole causation by the promisee. Secondly, cases of joint causation by both parties where the consequences of each contribution can be delimited. Thirdly, cases of joint causation where the consequences of each party's contribution cannot be delimited (shared responsibility). The third case type is investigated further and it is established that an apportionment based on a comparative evaluation of the parties is called for. However, problems occur in regard to the requirement to the causal link between the promisee and the promisor's failure to perform as well as in the choice between an objective or subjective approach to shared responsibility. The findings in this paper are based on the CISG text, preparatory works, scholarly works, case law and other international instruments.

Tracking Multiple Topics for Finding Interesting Articles  

Energy Technology Data Exchange (ETDEWEB)

We introduce multiple topic tracking (MTT) for iScore to better recommend news articles for users with multiple interests and to address changes in user interests over time. As an extension of the basic Rocchio algorithm, traditional topic detection and tracking, and single-pass clustering, MTT maintains multiple interest profiles to identify interesting articles for a specific user given user-feedback. Focusing on only interesting topics enables iScore to discard useless profiles to address changes in user interests and to achieve a balance between resource consumption and classification accuracy. Also by relating a topic's interestingness to an article's interestingness, iScore is able to achieve higher quality results than traditional methods such as the Rocchio algorithm. We identify several operating parameters that work well for MTT. Using the same parameters, we show that MTT alone yields high quality results for recommending interesting articles from several corpora. The inclusion of MTT improves iScore's performance by 9% to 14% in recommending news articles from the Yahoo! News RSS feeds and the TREC11 adaptive filter article collection. And through a small user study, we show that iScore can still perform well when only provided with little user feedback.

The ''Article Act'' - a substitute for the miscarried energy consensus?  

International Nuclear Information System (INIS)

A prerequisite for arriving at a long-term energy policy is that all political parties come to an energy consensus. This paper reviews the chronology of the energy consensus negatiations, their failure, and the consequent energy-political rerouting which is to be realised by an act securing hard coal a share in electricity generation and amending the Atomic Energy Act (termed 'Article Act'). The Article Act is an attempt at a binding definition of central issues of the energy consensus talks even in the absence of an all-party agreement. It is particularly noteworthy that the bill makes mention of both coal and nuclear energy, reviving this link-up between the two energy sources already decined lost. The German electricity industry considers the provisions on atomic energy law contained in the Article Act insufficient for securing already existing power plants an untroubled future and for providing the investment climate needed by the manufacturing industry. To the electricity industry the main problems lie in the execution deficits at the Laender level, but these are not affected by the Article Act. It is concluded that an all-party consensus on an answerable nuclear energy utilisation will have to be found by 1995 at the latest in order to give the manufacturing industry the go-alread for continuing research and provide electricity producers with a sound basis for investment decisions.

The Relevance of People’s Attitudes Towards Freedom of Expression in a Changing Media Environment  

Directory of Open Access Journals (Sweden)

Full Text Available The article outlines arguments for the relevance of people’s attitudes towards freedom of expression: It is a fundamental principle of democracy that if a virtue does not receive support from the population, it will not be anchored in law and its foundation is endangered in the medium term. People’s support for free speech is becoming even more influential because authoritative control of internet communication is faced with difficulties. Furthermore, with the development of social media users gain new opportunities to publicly express their opinions attaching even more importance to normative self-regulation. As a matter of fact, these increased opportunities of self-regulation may either enhance or decrease the exercise of expression rights. Thus, citizen’s endorsement of free expression is a valuable indicator of the status of freedom of expression in a country. To approach to the subject empirically, the paper systematizes findings on people’s attitudes towards free speech: Most people believe in freedom of expression in the abstract. Willingness to apply the right to opposing groups, however, is lower. Perceived threats, confidence in democratic principles, mode of communication, and personality variables influence tolerance of expressions. Finally, a research agenda is put forward to examine appreciation of free expression, its antecedence, and implications.

Towards an Analysis of Review Article in Applied Linguistics: Its Classes, Purposes and Characteristics  

Directory of Open Access Journals (Sweden)

Full Text Available The classes, purposes and characteristics associated with the review article in the field of applied linguistics were analyzed. The data were collected from a randomly selected corpus of thirty two review articles from a discipline-related key journal in applied linguistics. The findings revealed that different sub-genres can be identified within the applied linguistic review article genre. Three main types of review articles were therefore identified based on the analysis of linguistic devices often used by the authors, their communicative purposes, and the specialist informants’ feedback: (1 the bibliographic review article which gives readers a comprehensive and descriptive record of annual works and it encompasses the literature-oriented approach, (2 the critical evaluative review article which encompasses subject-oriented approach, that is to say it identifies an idea or raises a research problem, then gives its solution by analyzing and evaluating the selective works done before in the related field, and finally it suggests a new direction, and (3 the mixed-mode review article which has the twin roles and encompasses both literature-oriented and subject-oriented approaches. A possible colony of review genre was suggested and this study further examined some of the characteristics and purposes associated with the review articles. The classification continuum, purposes, characteristics, and linguistic devices of the review articles proposed thus provide useful guidance for graduate EFL (English as a Foreign Language students and novice writers how to monitor and make use of the review articles during their research writing.

The Pragmatics of Branding : An Application of Dewey's Theory of Aesthetic Expression  

DEFF Research Database (Denmark)

This article aims to explore the potential of Dewey's theory of aesthetic expression to expand knowledge about aesthetics in branding and better understand how brands work. The paper aims to mine the pragmatic theory of aesthetic expression as involving artistry, intention and imagination to reveal the role beauty plays alongside usefulness in defining and refining brand image and meaning. Design/methodology/approach: Dewey's dialectical method of holistically combining tensions such as beauty and usefulness is applied to brand theory and used to critique current brand management practices. Findings: The application of the theory of aesthetic expression emphasizes: understanding humans holistically in order to explain how beauty and expression create value and enrich lives; redefining brand ownership and use to accommodate the aesthetic ways people handle expression/expressiveness; and managing brands with appreciation of how beauty empowers them to attract users. Research limitations/implications: Seven dialectical tensions featured in Dewey's theory are identified and developed into holistic propositions for the future study of brands and branding: beauty/usefulness, act/object, inner/outer material, private/public, expression/statement, appreciation/control, symbolic/instrumental. Practical implications: The primary practical implication derived from application of the theory of aesthetic expression to brands and branding is that the most beautiful brands emerge from acts of co-creation that respect the artistry, intention and imagination of the brand's stakeholders. Originality/value: The article offers increased depth to the study of the expressive/emotional/aesthetic aspects of branding and offers an enriched aesthetic foundation for studying and practicing brand co-creation

Transforming Interior Spaces: Enriching Subjective Experiences Through Design Research  

Directory of Open Access Journals (Sweden)

Full Text Available This article explores tacit knowledge of lived experience and how this form of knowledge relates to design research. It investigates how interior designers interpret user lived experiences when creating designed environments. The article argues that user experience is the basis of a form of knowledge that is useful for designers. The theoretical framework proposed in the article examines the nature of user experience and how it can be utilized in the design process. The study of lived experiences is contextualized within aesthetic, subjective, and functional aspects of the interior design process, which requires users to express their meanings and needs. A case study is described to illustrate the various stages of this process.

Online handwritten mathematical expression recognition  

Science.gov (United States)

We describe a system for recognizing online, handwritten mathematical expressions. The system is designed with a user-interface for writing scientific articles, supporting the recognition of basic mathematical expressions as well as integrals, summations, matrices etc. A feed-forward neural network recognizes symbols which are assumed to be single-stroke and a recursive algorithm parses the expression by combining neural network output and the structure of the expression. Preliminary results show that writer-dependent recognition rates are very high (99.8%) while writer-independent symbol recognition rates are lower (75%). The interface associated with the proposed system integrates the built-in recognition capabilities of the Microsoft's Tablet PC API for recognizing textual input and supports conversion of hand-drawn figures into PNG format. This enables the user to enter text, mathematics and draw figures in a single interface. After recognition, all output is combined into one LATEX code and compiled into a PDF file.

Method for hot press forming articles  

Science.gov (United States)

This disclosure relates to an improved method for achieving the best bond strength and for minimizing distortion and cracking of hot pressed articles. In particular, in a method for hot press forming both an outer facing circumferential surface of and an inner portion of a hub, and of bonding that so-formed outer facing circumferential surface to an inner facing circumferential surface of a pre-formed ring thereby to form an article, the following improvement is made. Normally, in this method, the outside ring is restrained by a restraining sleeve of ring-shaped cross-section having an inside diameter. A die member, used to hot press form the hub, is so-formed as to have an outside diameter sized to engage the inside diameter of the restraining sleeve in a manner permitting relative movement therebetween. The improved method is one in which several pairs of matched restraining sleeve and die member are formed with each matched pair having a predetermined diameter. The predetermined diameter of each matched pair is different from another matched pair by stepped increments. The largest inside diameter of a restraining sleeve is equal to the diameter of the outer facing circumferential surface of the hub. Each pair of the matched restraining sleeve and die member is used to form an article in which an inside hub is bonded to an outside ring. The several samples so-formed are evaluated to determine which sample has the best bond formed between the hub and the ring with the least or no cracking or distortion in the ring portion of the article. Thereafter, the matched restraining sleeve and die member which form the article having the best bonding characteristics and least distortion cracking is then used for repeated formations of articles.

Analysis of status of citation of articles published in the Medical Journal of Chinese PLA from 2000 to 2009  

Directory of Open Access Journals (Sweden)

Full Text Available Objective ?Based on the status of citation of articles published in Medical Journal of Chinese PLA, to analyze the academic value of the Medical Journal of Chinese PLA, and provide information for assessing dominant medical disciplines and major groups of contributors, and for appraisal of outstanding articles. Methods ?The journal citation data were obtained from the China Academic Journal Network Publishing Database(CAJD. The individual citation data of the scientific articles published in Medical Journal of Chinese PLAfrom 2000 to 2009 were retrieved from CAJD. Articles with citation frequency equal to or higher than 30 times were collected for analysis, and they were defined as highly cited articles. Based on these highly cited articles, we analyzed the authors' institutions, research discipline distribution and types of research projects. We also made a vertical comparison of average citation frequency in every year. Results ?The total number of articles with citation frequency equal to or higher than 30 times was 50. The yearly average citation frequency increased year by year, from 0.05 times in the year 2000 to 4.46 times in the year 2009. Distribution of authors and institutions was as follows: authors of 11 articles were working in General Hospital of Chinese PLA and 302 Hospital of PLA respectively, authors of 6 articles were working in the Second Military Medical University, 5 in the First Military Medical University and Third Military Medical University, respectively, 4 in 304 Hospital of Chinese PLA. The articles from these 6 institutions accounted for 84% of all highly cited articles. Research fields distribution were as follows: 12 articles in infectious diseases, 7 in field surgery, 6 in trauma and burns. The articles in these 3 fields accounted for 50% of all highly cited articles. Research types were as follows: 20 articles of experimental research, 11 clinical research, 9 literature review, 8 expert forums and 2 dealing with clinical pathology. Conclusions ?Since 2000, the citation rate of articles published in the Medical Journal of Chinese PLAimproves significantly. The authors of these highly cited articles were mainly distributed in military medical universities and headquarter hospitals. The articles dealing with infectious diseases, field surgery, trauma and burns had higher citation frequency.

Production of scientific articles on health in six Latin American countries, 1973-1992  

Directory of Open Access Journals (Sweden)

Full Text Available The production of articles resulting from biomedical, clinical, and public health studies that originated in Argentina, Brazil, Chile, Cuba, Mexico, and Venezuela from 1973 through 1992 was analyzed to discover trends in health research in Latin America. From the database of the Institute for Scientific Information (ISI, 41 238 articles with first authors who resided in those countries were extracted. These articles were analyzed by subject area, type of study, country, number of authors and institutions that participated in the investigation, and citations received by each article. Also analyzed were 95 articles in epidemiology selected from a pool of 570 published by authors from the six countries in 11 public health journals that enjoy international prestige. The results showed that the number of published works increased by 117% between the first and last five-year periods within the study period. Clinical research was distributed the most evenly among the countries, and public health research was the most concentrated (60.7% originated in Brazil. The numbers of biomedical and public health research articles showed relatively more growth than those reporting on clinical research throughout the period. A relative decrease was found in articles by only one author, which suggests a greater frequency of team efforts, and an increase was seen in articles with authors tied to two or more national or foreign institutions, which indicates greater cooperation between institutions and countries. The average number of citations received by each article was three, which was less than half the number received per article in the ISI database (7.78. Regarding the subset of 95 articles in epidemiology, the great majority (96% dealt with infectious diseases or maternal and child health, while in the international literature 78% of such articles were about chronic diseases. This group of articles gave evidence of more cooperation with international institutions and had a citation index of 4.36 per article. It is concluded that, despite the inherent limitations, this type of study reveals some general trends in the development of research in the six Latin American countries with the greatest scientific production and makes it possible to formulate hypotheses on the factors that influence these trends. Taken with the proper caution, the results of studies like this one can be of great value in defining health science and technology policies.

Continuous, Dynamic and Comprehensive Article-Level Evaluation of Scientific Literature  

CERN Document Server

It is time to make changes to the current research evaluation system, which is built on the journal selection. In this study, we propose the idea of continuous, dynamic and comprehensive article-level-evaluation based on article-level-metrics. Different kinds of metrics are integrated into a comprehensive indicator, which could quantify both the academic and societal impact of the article. At different phases after the publication, the weights of different metrics are dynamically adjusted to mediate the long term and short term impact of the paper. Using the sample data, we make empirical study of the article-level-evaluation method.
