    Full Text Available Scientific writers might not inevitably be exact, precise and explicit in expression, eschewing vulnerability to criticism and seeking acceptability form academia. The present study aimed at investigating the frequency, form and function of the multi-objective linguistic and rhetorical device of hedging in the discussion sections of 100 qualitative and quantitative research articles where appropriate expression of scientific claims is highly welcome. As such, the taxonomy proposed by Hyland (1996 was applied in order to identify and classify the various hedge words, followed by an independent-samples t-test to compare the total number of hedging devices. The results revealed a statistically significant difference between qualitative and quantitative research articles with respect to both frequency and form of the employed hedge words, bearing important implications for educational researchers and practitioners in applying appropriate hedging strategies in the academic publishing of scientific texts.

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

    2010-04-01

    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.

Journal of Advanced Nursing00(0), 000-000. doi: 10.1111/j.1365-2648.2011.05898.x ABSTRACT: Aim.? This paper presents the development and validation of a new assessment tool for qualitative research articles, which could assess trustworthiness of qualitative research articles as defined by Guba and at the same time aid clinicians in their assessment. Background.? There are more than 100 sets of proposals for quality criteria for qualitative research. However, we are not aware of an assessment tool that is validated and applicable, not only for researchers but also for clinicians with different levels of training and experience in reading research articles. Method.? In three phases from 2007 to 2009 we delevoped and tested such an assessment tool called VAKS, which is the Danish acronym for Appraisal of Qualitative Studies. Phase 1 was to develop the tool based on a literature review and on consultation with qualitative researchers. Phase 2 was an inter-rater reliability test in which 40 health professionals participated. Phase 3 was an inter-rater reliability test among the five authors by means of five qualitative articles. Results.? The new assessment tool was based on Guba's four criteria for assessing the trustworthiness of qualitative inquiries. The nurses found the assessment tool simple to use and helpful in assessing the quality of the articles. The inter-rater agreement was acceptable, but disagreement was seen for some items. Conclusion.? We have developed an assessment tool for appraisal of qualitative research studies. Nurses with a range of formal education and experience in reading research articles are able to appraise, relatively consistently, articles based on different qualitative research designs. We hope that VAKS will be used and further developed.

    2014-03-01

    Full Text Available 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.

    Full Text Available Monarchy was the usual form of government in the medieval ages. Even in Europe and in Asiatic states outside India, this was the only form of Government the medieval king was necessarily the “Leviathan” of Hobbes enjoying all the “Divine Rights”. The central Government during the middle ages was only the apparition of the ruling kings. The king, as it were, was the revolving moon round the earth. He gave brightness and guided all the deliberations. Monarchy, however, was not absolute. Public opinion was a potent factor. But it cannot be denied that judicial administration during the medieval period was highly centralized. The king was the fountainhead of justice and decided most of the important cases personally. Even prominent officials and nobles were permitted to go unpunished for their acts of highhandedness and crimes, by the strong rulers who ruled the Vijayangara kingdom to understand the overall administrative nature of the kingdom. With this objective, the present article intends to portray the picture of judicial administration in Vijayanagara kingdom.

    The number of times an article has been cited in the peer-reviewed literature is indicative of its impact on its respective medical specialty. No study has used citation analysis to determine the most influential studies pertaining to the anterior cruciate ligament (ACL). The primary aims of this study were to identify the classic works in ACL research using citation analysis and to characterize these articles to determine which types of studies have had the most influence on the field. A systematic query of ISI Web of Science (Thomson Reuters, Philadelphia, Pennsylvania) was performed for articles pertaining to the ACL, and the 50 most-cited articles were selected for evaluation. The following characteristics were determined for each article: number of citations, citation density, journal, publication year, country of origin, language, article type, article subtype, and level of evidence. The number of citations ranged from 219 to 1073 (mean, 326), and the citation densities ranged from 4.9 to 55.6 citations per year (mean, 18.2). All articles were published in 1 of 11 journals, with the most being published in The American Journal of Sports Medicine (46%) and The Journal of Bone and Joint Surgery American (30%). The most common decades of publication were the 1990s (34%), 1980s (28%), and 2000s (26%). The majority (68%) of articles originated from the United States, and all were written in English. By article type, 42% were basic science, and 58% were clinical. Of the clinical articles, 3% were Level I, 17% were Level II, 28% were Level III, and 52% were Level IV. The articles were heterogeneous with regard to article type, article subtype, and level of evidence and tended to have the following characteristics: high-impact journal of publication, recent publication year, US origin, English language, and low level of evidence. These works represent some of the most popular scientific contributions to ACL research. This list may aid residency and fellowship programs in the compilation of articles for trainee reading curriculums. [Orthopedics. 2015; 38(4):e297-e304.]. PMID:25901623

    Duplicate publication is the republication of an article in which a lot of important parts overlap with the published copy. This issue is nearly at the top of the list of subjects, which medical journal editors discuss. this study was conducted with the purpose of investigating the publication patterns and determining it's root causes in research articles in the Isfahan University of Medical Science and to find a solution to prevent it. In a cross sectional study, All the discovered cases of duplicate publication, which were referred to the ethics committee of the Isfahan University of Medical Science during 2005–2008 were selected to be investigated through a descriptive method. After confirmation about the case of a duplicate publication, the requisite investigation was conducted through interviews and review of the correspondence and documentaries, and then, a radical line was charted. After investigating the cases and classifying the radical causes and incidents, categorization and definition of duplicate publication are presented. Eight out of nine republished articles belonged to the first category of Baily's index (copy publication) and one was in the third category (minimum publishable unit: Salami slicing). The results of the present article indicate that, the scientific community of the country is not yet familiar with the professional principles of scientific and research affairs. According to the results of this investigation, it is recommended to take official action against duplicate publication cases, violation of copyright, and also to have strict instructions against this unethical practice.

    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.

    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.

    2013-01-01

    Policies ensuring that research data are available on public archives are increasingly being implemented at the government [1], funding agency [2-4], and journal [5,6] level. These policies are predicated on the idea that authors are poor stewards of their data, particularly over the long term [7], and indeed many studies have found that authors are often unable or unwilling to share their data [8-11]. However, there are no systematic estimates of how the availability of research data changes with time since publication. We therefore requested datasets from a relatively homogenous set of 516 articles published between 2 and 22 years ago, and found that availability of the data was strongly affected by article age. For papers where the authors gave the status of their data, the odds of a dataset being extant fell by 17% per year. In addition, the odds that we could find a working email address for the first, last or corresponding author fell by 7% per year. Our results reinforce the notion that, in the long te...

    -The purpose of the study was to investigate the effects of research-article writing motivation and use of self-regulatory writing strategies in explaining second language (L2) research-article abstract writing ability, alongside the L2 literacy effect. Four measures were administered: a L2 literacy test, a research abstract performance assessment, and inventories of writing motivation and strategy. Participants were L2 graduate students in Taiwan (N = 185; M age = 25.8 yr., SD = 4.5, range = 22-53). Results of structural equation modeling showed a direct effect of motivation on research-article writing ability, but no direct effect of strategy or indirect effect of motivation via strategy on research-article writing ability, with L2 literacy controlled. The findings suggest research-article writing instruction should address writing motivation, besides L2 literacy. PMID:25706344

    Full Text Available The writer’s strategy to combine the exposition of factual information with personal judgement and interaction with the reader has been analysed in a number of studies (Hunston, 1994; Hyland, 1998a, 1998b; Latour and Woolgar, 1979; Skelton, 1997. Myers’ studies (1989, 1992 on the pragmatics of politeness in scientific articles analyse politeness strategies in regularities of scientific style that are usually explained in terms of conventions. In the context of scientific communication, the researcher performs two basic tasks: presenting a claim and contradicting former theories or beliefs. Both actions could be interpreted as impolite behaviours and constitute what Brown and Levinson (1987 call face threatening acts (FTAs. In this study we explore the presence of face-redressive politeness strategies in the discussion sections of engineering research articles. The data are drawn from a corpus of 46 discussion sections in the fields of computing, telecommunications, nanotechnology and robotics.La estrategia del escritor de combinar la exposición de información factual a la vez que expresa sus opiniones personales y mantiene la interacción con el lector ya ha sido objeto de análisis (Hunston, 1994; Hyland, 1998a, 1998b; Latour y Woolgar, 1979; Skelton, 1997. Los estudios de Myers (1989, 1992, enfocados a la pragmática de la cortesía en artículos científicos, analizan las estrategias de cortesía presentes en las regularidades del discurso científico, que tienden a ser consideradas como convenciones del género. En el contexto de la comunicación científica, el investigador realiza dos tareas básicas: presentar una hipótesis o afirmación científica y contradecir teorías u opiniones asumidas por la comunidad científica. Ambas acciones son susceptibles de ser consideradas descorteses y constituyen lo que Brown y Levinson (1987 denominan ‘actos de amenaza de la imagen pública’ (face threatening acts en su denominación inglesa. En este estudio se describen las estrategias de cortesía destinadas a preservar la imagen en las secciones de discusión de 46 artículos científicos pertenecientes a los campos de la informática, las telecomunicaciones, la nanotecnología y la robótica.

    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.

  17. Modals in the construction of research articles: A cross-disciplinary perspective

    Directory of Open Access Journals (Sweden)

    Matthew Peacock

    2014-03-01

    Full Text Available This paper describes a corpus-based analysis of variation in the distribution and function of modals and their role in the expression of “stance” in a corpus of 600 research articles (RAs across twelve disciplines. Stance is an expression of attitudes, judgments, or assessments towards the truth of propositions (Biber et al., 1999, and part of the important function of claiming and confirming membership of discourse communities and therefore in constructing identity. Three functional categories of modals perform a valuable role in the construction of stance: Possibility/Ability, Obligation/Necessity, and Prediction (Biber et al., 1999. However, very little research seems to have investigated variation across disciplines or their use in the RA. The corpus was analysed using WordSmith Tools (Scott, 2004, followed by manual checking of the function of every occurrence. Inter- and intra-rater agreement was also checked. Many statistically significant disciplinary differences were found, along with numerous marked differences with individual modals. Further examination of the corpus revealed considerable disciplinary variation in the patterns and verbs associated with the target modals, and a number of sub-functions of the topics covered by the modals. Conclusions are that modals perform an important role in the construction of stance.

  19. From I to D: Pronominal Discourse Functions Across the Sections of Research Articles

    Directory of Open Access Journals (Sweden)

    Mónica Chávez Muñoz

    2013-05-01

    Full Text Available Academic writing has been recently defined as a social activity in disciplinary communities and cultures. As a result, there has been an increasing interest in the study of self as author, focusing on the way writers represent themselves in texts and how writers interact with readers. Additionally, authorial presence has been analysed across languages and across sections of the research article. This study explores the usage pattern of pronominal discourse functions across sections of 60 research articles in the fields of linguistics, psychology and educational research in English and Spanish. Drawing on a modified version of Tang and John’s (1999 taxonomy of pronouns, I explain the frequency and usage of pronouns in each section of the research articles. The analysis of items revealed some differences and similarities in terms of linguistic choices writers make in a specific section of the research article in both languages.Keywords: research articles, text analysis, personal pronouns, metadiscourse, contrastive linguistics

    2012-04-01

    The first phase of Elsevier's Article of the Future article format was released on SciVerse ScienceDirect in January 2012. While this new format for online scholarly articles brings a significantly improved online presentation, it also enables further enhancements in terms of domain-specific content and contextualization of research results. Of particular interest to the Earth Sciences research community are the seamless integration of an interactive map viewer that displays author-submitted KML files inside the article, and real-time links to leading research data portals like Pangaea and Earthchem. These enhancements allow for a richer form of communication between authors and readers, and present researchers with valuable additional information in the context of the article. In this presentaion I will review these ongoing efforts to enhance online articles in the digital era.

  18. Research development of the relationship between thymidine phosphorylase expression and colorectal carcinoma

    Directory of Open Access Journals (Sweden)

    Ji-Min Zhang

    2013-03-01

    Full Text Available Thymidine phosphorylase (TP is a key enzyme that contributes to the composition and decomposition of pyrimidine nucleotides. TP seems homologous to platelet-derived endothelial cell growth factor, and its effects on inducing vascularization and anti-apoptosis are closely related to growth and metastasis of colorectal carcinoma. In addition, TP is a key enzyme that catalyzes the transformation from 5-fluorouracil (FU prodrugs of 5?-deoxy-5-fluorouridine (5?-DFUR to 5-FU. The activity of TP is closely related to the sensitivity of colorectal carcinoma cells to fluorouracil drugs and targeted therapy. Given the important functions of TP in growth, metastasis, tumor treatment, and prognosis, determining its expression mechanism is significant. This article summarizes the research development of TP expression in colorectal carcinoma, tumor neovascularization, cytotoxicity activation of 5?-DFUR, and colorectal carcinoma therapy.

  5. Invited Review Article: Advanced light microscopy for biological space research

    International Nuclear Information System (INIS)

    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

    2009-10-01

    Full Text Available The ultimate aim of intercultural analyses in English for Academic Purposes is to help non-native scholars function successfully in the international disciplinary community in English. The aim of this paper is to show how corpus-based intercultural analyses can be useful to design EAP materials on a particular metadiscourse category, logical markers, in research article writing. The paper first describes the analysis carried out of additive, contrastive and consecutive logical markers in a corpus of research articles in English and in Spanish in a particular discipline, Business Management. Differences were found in their frequency and also in the use of each of the sub-categories. Then, five activities designed on the basis of these results are presented. They are aimed at raising Spanish Business scholars' awareness of the specific uses and pragmatic function of frequent logical markers in international research articles in English.

    Full Text Available Abstract. Research into English research articles (RAs has largely been focused on articles produced by native English writers. This paper reports a study aiming to investigate the textual structure of research articles written by non-native English (i.e. Indonesian writers, which may contribute to their acceptance for international publication. A comparison is made between RAs written by native English speakers, an Indonesian writers writing in English, all in the field of Language and Language Teaching. It explores the relation of text's generic structure. The thesis develops a framework for the generic structure analysis based on Swales' (1990 Create-A­Research-Space (CARS model of moves. The analysis focuses on two RA sections: Introduction and Discussion. The findings indicate significant differences in both forms and functions of organizing strategics between the native and non-native texts. The differences may partly be due to the influence of writing practices in the non-native writers' first language and partly to the writer's attempt to find an appropriate format in the absence of well-established research writing conventions in the first language. Consequently, non-native English texts may show organizing strategies unfamiliar to both the native English and native Indonesian texts. Findings from the research highlight two issues. First, formal and functional differences of generic structure elements and their realizations between the native and non-native English texts may disadvantage the non-native writers, particularly with regards to employment of unfamiliar organizational

    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

  8. 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

    Full Text Available Objective(s: Diagnostic nuclear medicine is being increasingly employed in clinical practice with the advent of new technologies and radiopharmaceuticals. The report of the prevalence of a certain disease is important for assessing the quality of that article. Therefore, this study was performed to evaluate the quality of published nuclear medicine articles and determine the frequency of reporting the prevalence of studied diseases. Methods: We used Standards for Reporting of Diagnostic Accuracy (STARD and Quality Assessment of Diagnostic Accuracy Studies (QUADAS-2 checklists for evaluating the quality of articles published in five nuclear medicine journals with the highest impact factors in 2012. The articles were retrieved from Scopus database and were selected and assessed independently by two nuclear medicine physicians. Decision concerning equivocal data was made by consensus between the reviewers. Results: The average STARD score was approximately 17 points, and the highest score was 17.19±2.38 obtained by the European Journal of Nuclear Medicine. QUADAS-2 tool showed that all journals had low bias regarding study population. The Journal of Nuclear Medicine had the highest score in terms of index test, reference standard, and time interval. Lack of clarity regarding the index test, reference standard, and time interval was frequently observed in all journals including Clinical Nuclear Medicine, in which 64% of the studies were unclear regarding the index test. Journal of Nuclear Cardiology had the highest number of articles with appropriate reference standard (83.3%, though it had the lowest frequency of reporting disease prevalence (zero reports. All five journals had the same STARD score, while index test, reference standard, and time interval were very unclear according to QUADAS-2 tool. Unfortunately, data were too limited to determine which journal had the lowest risk of bias. In fact, it is the author’s responsibility to provide details of research methodology so that the reader can assess the quality of research articles. Conclusion: Five nuclear medicine journals with the highest impact factor were comparable in terms of STARD score, although they all showed lack of clarity regarding index test, reference standard, and time interval, according to QUADAS-2. The current data were too limited to determine the journal with the lowest bias. Thus, a comprehensive overview of the research methodology of each article is of paramount importance to enable the reader to assess the quality of articles.

    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.

    Full Text Available The present study aims to analyze comparatively English and Persian research articles (Linguistics, Literature, and Library and Information disciplines in terms of number and degree of utilization of sub-types of lexical cohesion in order to appreciate textualization processes in the two languages concerned. The study analyzes 60 research articles (30 articles in each language in terms of sub-types of lexical cohesion. The study reveals that the order of occurrence in descending order of sub-types of lexical cohesion is ( Rep., Col., Syn., Gen.N., Mer., Hyp., and Ant. in English data, while the order in Persian data is ( Rep., Syn., Col., Ant., Hyp., Mer., Gen.N.. In both data the most frequent sub-types are repetition, collocation, synonymy. In English data the general tendency is towards the use of repetition and collocation but Persian data show the general tendency towards the use of repetition and synonymy. This study might have implications for teachers and researchers in the field of teaching English as a foreign language because of the fact that teaching sub-types of lexical cohesion to foreign language learners will improve the quality of their reading and writing.

    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.

    2000-01-01

    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.

    2006-08-01

    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.

    Full Text Available The study tried to discover disciplinary distinctions between Persian and English in the academic genre. The focus was on the use of metadiscourse in the discipline of computer engineering research articles across the two languages. The selected corpus was analyzed through the model suggested by Hyland and Tse (2004. The results demonstrated that the two languages are distinct in their use of metadiscourse in the discipline studied. It was found that Persian, unlike English, relied on interactive resources more. The disciplinary distinction indicates that Persian computer engineering provides more textual elements while English language values a reader responsible trend.

    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.

    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

    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.

In general, this skill is automatic for many practitioners and researchers who already possess a good working knowledge of research methodology, including: hypothesis development, sampling techniques, study design, testing procedures and instrumentation, data collection and data management, statistics, and interpretation of findings. For graduate students and junior faculty who have yet to master these skills, completing a formally written article critique can be a useful process to hone such skills. However, a fundamental knowledge of research methods is still needed in order to be successful. Because there are few published examples of critique examples, this article provides the practical points of conducting a formally written quantitative research article critique while providing a brief example to demonstrate the principles and form.

    Full Text Available Reviewing literature reveals that identifying generic structure of research articles (RAs in different fields of study, especially ESP, has received much attention. The major purpose behind such trends of research has been raising researchers' awareness of the common conventions in writing RAs. Along with this universal trend, a lot of genre studies have been done in Iranian context; however, it seems that ESP RAs have not been paid due attention yet. Hence this study aimed at investigating the generic structure of ESP RAs in international and Iranian journals. Applying Kanoksilapatham's (2007 model to the compiled corpus, it was found that contextualizing the study (Move 1 and consolidating results (Move 2 were the obligatory moves in Discussion section of ESP RAs across international and Iranian journals. Evaluation of the findings was a new step found in international Discussion sections but absent in Iranian ones. Related discussion of these findings prepares the researchers for publishing in international and Iranian ESP journals.Keywords: ESP, Discussion section, Move, Step, Author presence, Generic structure

    Full Text Available A growing number of funding agencies and international scholarly organizations are requesting that research data be made more openly available to help validate and advance scientific research. Thus, this is an opportune moment for research data repositories to partner with journal editors and publishers in order to simplify and improve data curation and publishing practices. One practical example of this type of cooperation is currently being facilitated by a two year (2012-2014 one million dollar Sloan Foundation grant, integrating two well-established open source systems: the Public Knowledge Project’s (PKP Open Journal Systems (OJS, developed by Stanford University and Simon Fraser University; and Harvard University’s Dataverse Network web application, developed by the Institute for Quantitative Social Science (IQSS. To help make this interoperability possible, an OJS Dataverse plugin and Data Deposit API are being developed, which together will allow authors to submit their articles and datasets through an existing journal management interface, while the underlying data are seamlessly deposited into a research data repository, such as the Harvard Dataverse. This practice paper will provide an overview of the project, and a brief exploration of some of the specific challenges to and advantages of this integration.

    Full Text Available 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.

    2010-10-01

    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.

    Full Text Available Scientific discourse is characterized by highly normative and strict genre constraints on language use, both on the macro (text and micro (word level. The purpose of this article is to study the distribution of the French indefinite pronoun on and its interpretative values across the sections of French-language medical articles (KIAP corpus in the IMRAD format (Introduction, Methods, Results and Discussion. The main hypothesis is that the IMRAD structure entails a specific distribution of macro level textual structures (author roles, argumentation, rhetorical functions, and that this is reflected in the distribution of micro level linguistic markers, such as the pronoun on. Previous studies based on a more limited material (Gjesdal, 2008 indicate that the variation in the interpretative values of on seems to be influenced by the IMRAD format, and, furthermore, that the different values seem to correspond to different author roles. Particular emphasis will be put on the influence of the linear sequencing of text imposed by the IMRAD format and the distribution of author roles and speech acts across the text.Le discours scientifique se caractérise par des contraintes rigoureuses sur la production linguistique au niveau micro-linguistique (mot aussi bien qu’au niveau macro-linguistique (texte.

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

    DEFF Research Database (Denmark)

    Maier, Carmen Daniela

    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 Differentiated cells can change to embryonic stem cells by reprograming. Generation of induced pluripotent stem cells (iPSCs has revolutionized the field of regenerative and personalized medicine. iPSCs can self-renew and differentiate into many cell types. iPSC cells offer a potentially unlimited source for targeted differentiation. Through the expression of a set of transcription factors, iPSCs can be generated from different kinds of embryonic and adult cells. This technology for the first time enabled the researchers to take differentiated cells from an individual, and convert them to another cell type of interest, which is particularly to that person. When the set of master transcription factors containing OCT4, SOX2, KLF4, and MYC is expressed ectopically in somatic cells, the transcriptional network is propelled to organize itself in such a way as to maintenance a pluripotent state. Since iPSCs are similar to Embryonic Stem Cell (ESC, they can be considered as sources for modeling different diseases. iPSCs which are induced from somatic cells of patient can be useful for screening and drugs selection, and also introduce treatment via grafting the cells. Although this technology has been successful in different fields, the tumorigenesis of viral vectors during induction of reprogramming is a major challenge. Nevertheless, iPSCs are valuable for clinical applications and research. By discovery of these cells many challenges related to the safety, efficacy, and bioethics of ESCs are solved. Pluripotency is defined in two aspect of functional and molecular, by which functional regards the capacity of cell is generate three kinds of embryonic layers and germ line, and molecular aspect regards the identifying of molecules and genes that support functional features. Identification of these genes has been placed at the center of fields related to development and stem cell research. In this review, we discuss the process of generation of these cells, as well as required genes and factors for pluripotency, and also current progress in generation of iPSCs utilizing tens of reliable and new studies.

    2003-12-01

    A novel, improved dual bacterial-expression system, designed for large-scale generation of high-quality polyclonal antibody preparations intended for proteomics research, is presented. The concept involves parallel expression of cDNA-encoded proteins, as a fusion with two different tags in two separate vector systems. Both systems enable convenient blotting procedures for expression screening on crude bacterial cell cultures and single-step affinity purification under denaturing conditions. One of the fusion proteins is used to elicit antibodies, and the second fusion protein is used in an immobilized form as an affinity ligand to enrich antibodies with selective reactivity to the cDNA-encoded part, common for the two fusion proteins. To evaluate the system, four cDNA clones from putative nuclear proteins from the non-biting midge Chironomus tentans were expressed. Antibodies to these cDNA-encoded proteins were generated, enriched and used in blotting and immunofluorescence procedures to determine expression patterns for the native proteins corresponding to the cDNAs. The four antibody preparations showed specific reactivity to the corresponding recombinant cDNA-encoded proteins, and three of the four antibodies gave specific staining in Western-blot analysis of nuclear cell extracts. Furthermore, two of the antibody preparations gave specific staining in immunofluorescence analysis of C. tentans cells. We conclude that the dual-vector concept presented offers a highly stringent strategy for the generation of monospecific polyclonal antibodies, which are useful in proteomics research. PMID:12875650

    Full Text Available Previous quantitative studies suggest that the burden researchers who use English as an additional language perceive when writing research articles (RAs for publication in English (as L2 is 24% greater than the burden they perceive when they write RAs for publication in their L1. It remains unclear precisely which aspects of research article (RA writing in English present these writers with the greatest challenge and just why they perceive this increase in difficulty. A structured questionnaire comprising thirty-seven questions about researchers’ publication experiences in scientific journals in English and in Spanish was designed and sent out to all (n = 8,794 Spanish postdoctoral researchers at one research-only institution and four universities in Spain, yielding responses from 1,717 researchers. Our first results show that the discussion is the section that is perceived as more difficult to write for English-medium journals, across the four broad knowledge areas in a way that cannot be fully explained by their lower level of proficiency in English (as L2. This article proposes the rhetorical transfer hypothesis as a possible explanation for their additional difficulty. Our results also reveal that their increased perceived difficulty writing RA discussions in English (as L2 does not decrease noticeably until Spanish researchers report high or very high levels of proficiency in English (as L2 for academic or general purposes or have published on average at least 37 RAs as corresponding author in English-medium journals over the last ten years. Implications for English for Academic Purposes (EAP research and pedagogy are discussed.

    Full Text Available Histochemistry provides the unique opportunity to detect single molecules in the very place where they exert their structural roles or functional activities: this makes it possible to correlate structural organization and function, and may be fruitfully exploited in countless biomedical research topics. Aiming to estimate the impact of histochemical articles in the biomedical field, the last few years citations of articles published in a long-established histochemical journal have been considered. This brief survey suggests that histochemical journals, especially the ones open to a large spectrum of research subjects, do represent an irreplaceable source of information not only for cell biologists, microscopists or anatomists, but also for biochemists, molecular biologists and biotechnologists.

    Directory of Open Access Journals (Sweden)

    H. Russell Searight

    2011-03-01

    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.

    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.

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

    Directory of Open Access Journals (Sweden)

    Marcio Wagner Camatta

    2008-08-01

    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.

  17. Media Articles Describing Advances in Scientific Research as a Vehicle for Student Engagement Fostering Climate Literacy

    Science.gov (United States)

    Brassell, S. C.

    2014-12-01

    "Records of Global Climate Change" enables students to fulfill the science component of an undergraduate distribution requirement in "Critical Approaches" at IU Bloomington. The course draws students from all disciplines with varying levels of understanding of scientific approaches and often limited familiarity with climate issues. Its discussion sessions seek to foster scientific literacy via an alternating series of assignments focused on a combination of exercises that involve either examination and interpretation of on-line climate data or consideration and assessment of the scientific basis of new discoveries about climate change contained in recently published media articles. The final assignment linked to the discussion sessions requires students to review and summarize the topics discussed during the semester. Their answers provide direct evidence of newly acquired abilities to assimilate and evaluate scientific information on a range of topics related to climate change. In addition, student responses to an end-of-semester survey confirm that the vast majority considers that their knowledge and understanding of climate change was enhanced, and unsolicited comments note that the discussion sessions contributed greatly to this advancement. Many students remarked that the course's emphasis on examination of paleoclimate records helped their comprehension of the unprecedented nature of present-day climate trends. Others reported that their views on the significance of climate change had been transformed, and some commented that they now felt well equipped to engage in discussions about climate change because they were better informed about its scientific basis and facts.

  1. Research Article Abstracts in Two Subdisciplines of Business—Move Structure and Hedging between Management and Marketing

    Directory of Open Access Journals (Sweden)

    Qian Li

    2014-12-01

    Full Text Available The importance of RA abstracts lies in their influence on the readers’ decision about whether the accompanying article is worth reading. A number of studies have investigated the move structure of abstracts and have generated several influential models. However, little research has been conducted on subdisciplinary variations in move structure of abstracts. Additionally, previous studies have investigated independently either the move structure or the hedging use of academic writings. The attempt of the integration of the both have been lacking yet. Therefore, this study reports the analysis of move structure and hedging use in Management and Marketing abstracts. Comparative analysis was also conducted to investigate sudisciplinary variations in both move structure and hedging use between the two subdisciplines in the field of Business. In total, sixty-four research articles abstracts published in 2012 were randomly selected form eight leading journals in two subdisciplines. Hyland’s model (2000 was adopted as analytical framework for move structure analysis, and Wordsmith Tool was used to search hedging in the corpus. Results showed that the move structure of I-P-Pr (Introduction-Purpose-Product is the most dominant sequences in both Management and Marketing. Regarding the use of hedging, all the five types occurred in both subdisciplines of Business. The findings of this study have also demonstrated the existence of variations in terms of both move structure and the use of hedging in the abstracts between the two subdisciplines. Therefore, pedagogical implications can be proposed that teaching practices should address the variations so as to meet the specific expectations from different particular discourse communities.

This paper (Part I aims to have a comparative study between the predictions by codes of practice of BS8110 and EC2 and those equations by Darwin et al, Morita and Fuji, Batayneh and Nielsen and results of 164 tests from literature. In this part the case of straight anchorage bars without transverse pressure is considered. Some major parameters including compressive strength, and in terms of ratio of concrete cover to bar diameter and ratio of anchorage length to bar diameter , are addressed in detail. Although various parameters are involved in anchorage design equations, it is observed that every code has merit over the other codes in some aspect. The presented discussion highlights the major areas of differences which need attentions in the future for more investigations. The main conclusion has been presented in part II to include the study of straight anchorages with transverse pressure. The conclusions should cover the both cases to obtain the fair assessments for bond strength by those expressions used in this study

    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.

    Full Text Available Hedging is a linguistic strategy frequently employed in scientific writing to diminish the author‘s commitment to the accompanying proposition and to mitigate claims, thus presenting a proposition as a possibility or probability rather than a fact. This article describes the results of a pilot study on the frequency and variety of hedging devices in Lithuanian and English research articles in two different disciplines (linguistics and medicine. The study is limited to lexical hedges only. The results of a cross – disciplinary study demonstrate that in the field of medicine, researchers tend to hedge less and hence are much more determined in their claims than linguists in both languages. The cross – linguistic study shows that English speaking researchers seem to use significantly more hedging devices than their Li­thuanian speaking colleagues in both disciplines. The variety of hedges used in English was also wider than in Lithuanian. Most frequently used hedges in both languages in linguistic articles were adverbs, whereas in medical articles it was modal verbs.

    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

    Full Text Available Researchers in the field of automatic translation and natural language processing have been using the Web as a language resource for a number of years. Likewise, mastery of the advanced syntax of the Web's search engines, in order to retrieve the appropriate terminological and phraseological information, has now become an important element among the specialized translator's necessary skills, especially in the field of medicine, which is widely covered on the Web. In the case of noun phrases, checking the currency of the various word groupings that can be inferred when analyzing a syntactically ambiguous expression (whether on the Web or in digital corpora yields interesting results for the improvement of existing computer applications. Yet, the use of annotated corpora to retrieve potentially ambiguous noun phrases also has pedagogical applications, both in terms of attracting students' attention to some common pitfalls and providing them with the tools that they need in order to solve the difficulties that such structures create. ---------------------------------------------------- Uso de la Web y de corpus informáticos para la traducción de grupos nominales complejos en artículos de investigación médica. Los investigadores dedicados a la traducción automática y el procesamiento del lenguaje natural han utilizado la Web como recurso lingüístico desde hace ya bastante tiempo. Del mismo modo, el conocimiento profundo de la sintaxis avanzada para recuperar la información terminológica y fraseológica correcta en los buscadores de la red se ha convertido en un conocimiento que los traductores especializados deben añadir a sus destrezas básicas, especialmente en el campo de la medicina, tan ampliamente cubierto en la red. En el caso de grupos nominales, la comprobación de la vigencia de los distintos grupos de palabras que pueden utilizarse para analizar una expresión ambigua desde el punto de vista sintáctico (en la red o en corpus digitales, rinde interesantes resultados para mejorar las aplicaciones informáticas existentes. Sin embargo, el uso de corpus anotados para recuperar frases nominales potencialmente ambiguas también tiene aplicaciones pedagógicas, tanto para atraer la atención de los estudiantes hacia algunos escollos comunes como para brindarles los instrumentos necesarios para resolver las dificultades derivadas de dichas estructuras.

  15. Anti-tumor effect of a recombinant plasmid expressing human interleukin-12: an initial research

    International Nuclear Information System (INIS)

    Objective: To study the anti-tumor effect of a recombinant plasmid expressing human interleukin-12 (pEGFP-CIIL- 12) in vivo and in vitro. Methods: We transduct the recombinant gene (pEGFP-CIIL-12) to liver cancer cell HepG2 in vitro, and detect reproductive activity of the cell using MTT and the activity of expressing vascular endothelial growth factor(VEGF) using semiquantitative PCR. And then, we deliver the gene to rabbit liver tumor tissue intraarterial and combine with chemoembolization to observe the anti- tumor effect to VX2 tumor in vivo. Results: There are no statistical difference compared With control group in activity of reproductive and expressing VEGF in vitro. In vivo, tumor growth rate significantly reduce in gene therapy combined with chemoembolization group. Conclusion: Recombinant gene (pEGFP-ClIL-12) exhibit significant anti-tumor effect in vivo but not in vitro, perhaps the anti-tumor effect is associated with an indirect pathway instead of a direct pathway.

    Full Text Available La justificación de los objetivos de investigación es una parte consustancial de la producción científica. A pesar de ello, no existen descripciones detalladas de cómo esta práctica se realiza en distintas áreas de la ciencia. En este trabajo analizamos los extractos textuales de justificación de un corpus representativo de 162 artículos de investigación, correspondientes a seis áreas de la ciencia. Utilizando los lineamientos de la teoría fundada, los resultados del análisis muestran que la justificación no siempre se plasma en un movimiento retórico determinado en estos textos. Se puede establecer, además, que el ámbito de justificación puede corresponder a problemáticas o argumentos de distinto nivel, y que la forma más común de justificar una investigación se basa en los aportes, implicancias o aplicabilidad de los resultados. Por último, proponemos que las formas retóricas que adopta la justificación son sensibles a las variaciones determinadas por la naturaleza epistemológica, los objetos de estudio y los procedimientos metodológicos utilizados en cada una de las áreas de la ciencia. (The justification of research objectives is an inherent part of scientific production. However, there are not any detailed descriptions as to how this practice is carried out in different scientific areas. In this article, we analyzetextual extracts of justification from a representative corpus of 162 research articles, corresponding to six scientific disciplines. Using the guidelines of the Grounded Theory, the results of the analysis show that the justification is not always expressed as a determined rhetorical move in these texts. Furthermore, it can be established that the field of justification can correspond to problems and arguments of distinctive levels, and that the most common way to justify a research project is based on the contributions, implicationsor applicability of the results. Finally, we propose that the rhetoric forms that the justification takes are sensible to variations determined by the nature of epistemology, the objects of study and the methodological procedures used in each of the scientific areas.

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

    DEFF Research Database (Denmark)

    Elleby, Anita; Ingwersen, Peter

    2011-01-01

    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 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 five-year periode 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 publicy accessible through 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 article in WoS and GS and working papers in GS, more than doubling the amount of citations received through the latter source.

    Background Rotator cuff tendinopathy including tears is a cause of significant morbidity. The molecular pathogenesis of the disorder is largely unknown. This review aimed to present an overview of the literature on gene expression and protein composition in human rotator cuff tendinopathy and other tendinopathies, and to evaluate perspectives of proteomics – the comprehensive study of protein composition - in tendon research. Materials and Methods We conducted a systematic search of the literature published between 1 January 1990 and 18 December 2012 in PubMed, Embase, and Web of Science. We included studies on objectively quantified differential gene expression and/or protein composition in human rotator cuff tendinopathy and other tendinopathies as compared to control tissue. Results We identified 2199 studies, of which 54 were included; 25 studies focussed on rotator cuff or biceps tendinopathy. Most of the included studies quantified prespecified mRNA molecules and proteins using polymerase chain reactions and immunoassays, respectively. There was a tendency towards an increase of collagen I (11 of 15 studies) and III (13 of 14), metalloproteinase (MMP)-1 (6 of 12), -9 (7 of 7), -13 (4 of 7), tissue inhibitor of metalloproteinase (TIMP)-1 (4 of 7), and vascular endothelial growth factor (4 of 7), and a decrease in MMP-3 (10 of 12). Fourteen proteomics studies of tendon tissues/cells failed inclusion, mostly because they were conducted in animals or in vitro. Conclusions Based on methods, which only allowed simultaneous quantification of a limited number of prespecified mRNA molecules or proteins, several proteins appeared to be differentially expressed/represented in rotator cuff tendinopathy and other tendinopathies. No proteomics studies fulfilled our inclusion criteria, although proteomics technologies may be a way to identify protein profiles (including non-prespecified proteins) that characterise specific tendon disorders or stages of tendinopathy. Thus, our results suggested an untapped potential for proteomics in tendon research. PMID:25879758

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.

    Full Text Available Introdução: O cancro do estômago permanece um dos mais frequentes, especialmente nos países em desenvolvimento, pelo que poderá tornar-se numa doença negligenciada no que respeita aos esforços de investigação. O Japão apresenta das mais elevadas taxas de incidência em todo o mundo e contribui actual [...] mente para a maior parte das publicações científicas nesta área. Sendo Portugal um dos países com mais elevada frequência de cancro do estômago no mundo desenvolvido, o objectivo deste estudo foi caracterizar, quanto aos objectivos dos estudos e afiliação dos autores, as publicações sobre adenocarcinoma gástrico e/ou lesões pré-cancerosas do estômago publicadas por investigadores portugueses. Métodos: Pesquisámos as bases de dados MEDLINE® e Index de Revistas Médicas Portuguesas no período 19922003 e revimos os resumos dos artigos identificados. Excluíram-se os que não reportavam investigação original e os baseados exclusivamente no estudo de linhas celulares ou em experimentação animal. Obtivemos o número de citações dos artigos publicados em revistas internacionais através da Web of Science®. Resultados: Identificaram-se 88 artigos em revistas internacionais e 53 em revistas nacionais. Os artigos de pendor clínico são mais frequentemente publicados em revistas portuguesas e a investigação dos factores de risco e da etiologia nas publicações internacionais. 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 the scarce number of published works addressing the etiological

    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.

  15. Linking Assessment Questions to a Research Article to Stimulate Self-directed Learning and Develop High-order Cognitive Skills in an Undergraduate Module of Molecular Genetics

    Science.gov (United States)

    2009-01-01

    Assessment plays a crucial role in the learning process, but current assessments focus on assessment of learning rather than assessment for learning. In this study, a novel method for open-book continuous assessment (CA) was developed. The aim was to encourage students to learn beyond the textbook by challenging students with questions linked to a research article. Research articles closely related to lecture contents were selected and released to students before the CA for perusal. CA questions were set at three different levels to assess conceptual understanding, application, and synthesis. The CA was administered to first-year undergraduate students majoring in life science as part of Molecular Genetics, a compulsory module. It contributed 10% of the student's grade for the module. Students’ CA scores indicated that the majority could answer correctly all the questions. Students’ feedback on the CA showed that most of them praised the CA model for its novelty, motivation, and application. Only a few criticized it due to its poor coverage of lecture contents. Overall, this CA went beyond the traditional role of assessments in the assignment of scores and stimulated curiosity and self-directed learning. PMID:19952097

    Chaplin, Tara M.

    2015-01-01

    Small but significant gender differences in emotion expressions have been reported for adults, with women showing greater emotional expressivity, especially for positive emotions and internalizing negative emotions such as sadness. But when, developmentally, do these gender differences emerge? And what developmental and contextual factors influence their emergence? This article describes a developmental bio-psycho-social model of gender differences in emotion expression in childhood. Prior empirical research supporting the model, at least with mostly White middle-class U.S. samples of youth, is presented. Limitations to the extant literature and future directions for research on gender and child emotion are suggested.

    Full Text Available Objective: Nonverbal learning disability (NVLD is a condition associated with prominent nonverbal deficits such as reduced perceptual and spatial abilities, while the verbal abilities remain relatively intact. Some researchers have reported that there is a considerable overlap between cognitive and behavioral features of Asperger’s Disorder (AD and NVLD. The present study aimed to assess the hypothesis of the presence of NVLD in AD using a neuropsychological battery, which primarily focused on memory, in a group of children and adolescents from the Turkish population. Methods: 21 individuals, aged 7-16 years, - who referred to Istanbul Medical Faculty Child Psychiatry Department and were diagnosed with AD according to DSM-IV criteria, and 18 age-, gender-, IQ- and education level-matched volunteer controls were evaluated. The Wechsler Intelligence Scale for Children-Revised, California Verbal Learning Test-Children’s Version, Rey-Osterrieth Complex Figure Test, and The Benton Judgment of Line Orientation and Facial Recognition tests were administered to the participants.Results: The AD group performed similarly to the controls on verbal memory and verbal comprehension, but was significantly poorer in short- and long-term visual memory, perceptual organization and visuospatial constructional abilities. Conclusion: This study confirmed that the neuropsychological profile of the individuals with AD is closely similar to that of NVLD. (Archives of Neuropsychiatry 2011; 48: 140-6

  2. The role of energy in creating opportunities for income generation in the Indian Himalayas Original Research Article

    Energy Technology Data Exchange (ETDEWEB)

    Kooijman-van Dijk, A.L.

    2012-02-15

    Although it is clear that there are links between access to modern energy carriers and economic development, the necessary understanding of these links is lacking. Research in literature shows mixed results. This paper studies the mechanisms that link energy supply and impacts on income generation. Empirical data from 264 small scale enterprises in 16 clusters of villages in the Indian Himalayas is analysed. The steps between energy supply and impacts on enterprise are stratified, studying actual energy use of energy services. The analysis shows that for the majority of typical enterprises in rural areas, which are informal enterprises with less than 6 workers, the impacts on incomes are low even though the uptake of electricity in enterprises is high. The key factor influencing impacts on incomes is limitations in access to markets for enterprise products, especially social access. For most small scale rural entrepreneurs the main impacts of energy access are on wellbeing. The findings are discussed to come to policy recommendations in the field of energy supply and complementary fields to achieving positive impacts on rural development.

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

  7. 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)

    Objective: To examine the expression of MMP-2 gene and Survivin gene in subclinical microscopic tumor and its peripheral normal esophageal tissues, and study the radiation target in molecular level. Methods: Esophageal squamous cancer and its peripheral tissue samples of 34 patients were cut into sequential sections. The expression of MMP-2 gene and Survivin gene then examined. The length of the peripheral esophageal tissue, positively expressing the two genes, was measured, and the relation among the experimental date, tumor stage and vertical length of tumor were analyzed. Results: For tumor tissue, subclinical microscopic tumor and the peripheral differentiated normal tissue, the positive expression rate of MMP-2 was 85%, 83% and 79%, respectively. The positive expression rate of Survivin was 76%, 85% and 85%, respectively. The positive expression level of both MMP-2 and Survivin genes in subclinical microscopic tumor was significantly higher than that in the peripheral differentiated normal tissue (?2=6.46, P= 0.028 and ?2=16.15, P=0.001). The length was 17.2 -70.4 mm and 15.0 - 82.4 mm of cancerous peripheral tissue with positive expression of MMP-2 gene upside and downside of the tumor. The length was <70 mm in 97% of the samples. For Survivin gene,the length was 3.7-76.4 mm and 16.1-56.3 mm, and was < 70 mm in 96% of the samples. The length of cancerous peripheral esophageal tissue expressing the two genes increased significantly along wwo 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)

    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.

Abstract in english This article is the result of the research project entitled "Path and impact of the strategy of research hotbeds at University of Antioquia, for the University and the local and national context." In particular, it examines the relationship between two concepts that have been incorporated into the s [...] peech in research training of all Colombian universities: Formative research and Research in the strict sense of the term. The results reflect the coexistence of a multiplicity of theoretical-methodological approaches in which those relationships are expressed, which in the long run, end up by identifying the strategies under which researchers are currently being trained in Colombia. It can be concluded that it is necessary a deep debate about the pedagogical conditions for the training of researchers. It is a pending task for an academic community, which in some cases, has uncritically received the documents of national policy.

    Full Text Available Within current economy context, complexities and particularities most companies are constantly seeking to maximize effectiveness and efficiency of their business. 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.

    The welfare of research participants must be guaranteed by international ethical standards. This article communicates the procedures of the Research Ethics Committee of the School of Medicine, University of Chile (CEISH). The new Chilean legislation on research in human beings is also discussed. Law 20.120: "On scientific research in human beings, its genome and forbidding human cloning" establishes the ethical principles that must be accomplished in every research involving human beings. Article 28 of the Law 20.584 "Regulation of the rights and duties of health care users", forbids the participation of handicapped people who cannot express their will in scientific research. Article 13 states that people not related directly with patient care cannot have access to his clinical records (with the exception of people with notarial authorization by the patient). CEISH proposes that, in case of people with intellectual deficiency, the decision to approve a scientific research should be analyzed on an individual basis. If the person is capable of expressing his or her will or has stated his or her consent beforehand, the research can be authorized. If the person cannot express his or her will, the scientific research cannot take place. In prospective studies, a consent from the patient and an authorization of the health authority should be required to access clinical records. In retrospective studies, consent should be obtained from the patient when personal information is going to be used. If the information is nameless, the consent can be disregarded. PMID:25378008

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.

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.

    Full Text Available The purpose of this research was to examine the validity of Lotka and Pao’s laws with authorship distribution of "Computer Science" and "Artificial Intelligence" fields using Web of Science (WoS during 1986 to 2009 and comparing the results of examinations. This study was done by using the methods of citation analysis which are scientometrics techniques. The research sample includes all articles in computer science and artificial intelligence fields indexed in the databases accessible via Web of Science during 1986-2009; that were stored in 500 records files and added to "ISI.exe" software for analysis to be performed. Then, the required output of this software was saved in Excel. There were 19150 articles in the computer science field (by 45713 authors and 958 articles in artificial intelligence field (by 2487 authors. Then for final counting and analyzing, the data converted to “Excel” spreadsheet software. Lotka and Pao’s laws were tested using both Lotka’s formula: (for Lotka’s Law; also for testing Pao’s law the values of the exponent n and the constant c are computed and Kolmogorov-Smirnov goodness-of-fit tests were applied. The results suggested that author productivity distribution predicted in “Lotka's generalized inverse square law” was not applicable to computer science and artificial intelligence; but Pao’s law was applicable to these subject areas. Survey both literature and original examining of Lotka and Pao’s Laws witnessed some aspects should be considered. The main elements involved in fitting in a bibliometrics method have been identified: using Lotka or Pao’s law, subject area, period of time, measurement of authors, and a criterion for assessing goodness-of-fit.

    Construction of co-expression network and extraction of network modules have been an appealing area of bioinformatics research. This article presents a co-expression network construction and a biologically relevant network module extraction technique based on fuzzy set theoretic approach. The technique is able to handle both positive and negative correlations among genes. The constructed network for some benchmark gene expression datasets have been validated using topological internal and external measures. The effectiveness of network module extraction technique has been established in terms of well-known p-value, Q-value and topological statistics. PMID:24845500

    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.

  8. Emotional Expression in Reality TV

    DEFF Research Database (Denmark)

    Rasmussen, Tove Arendt

    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.

  15. El resumen del artículo de investigación: Análisis del género en un corpus de textos de Enfermería / The research article abstract: Genre analysis in a Nursing corpus of texts

    Scientific Electronic Library Online (English)

    2015-03-01

    Full Text Available El resumen es un género que ha recibido un tratamiento desigual en la literatura especializada; mientras en biomedicina, ciencias sociales y otras disciplinas afines numerosos autores han estudiado el resumen (Salager-Meyer, 1990; Hyland, 2000; Swales & Feak, 2009); en otras, en cambio, se les ha pr [...] estado escasa atención en lo que a su estructura y contenido se refiere y, concretamente, en Enfermería. Su importancia en la diseminación de la ciencia debería ser un acicate para dotar el resumen de una mayor información y fuerza persuasiva. Lo poco que se ha escrito sobre el resumen no aborda la problemática de si el resumen debe seguir el modelo tradicional de un solo párrafo o el estructurado con subtítulos (Posteguillo Gómez & Piqué-Angordans, 2007). El objetivo del presente estudio es describir el contenido y estructura del resumen tradicional así como los elementos textuales y discursivos del mismo. Siguiendo el modelo de la literatura especializada (Weissberg & Buker, 1990), se ha realizado un análisis de un corpus de 240 resúmenes extraídos de artículos de doce revistas de Enfermería mediante la identificación de sus unidades estructurales. Entre los resultados más significativos destaca la amplia variabilidad en cuanto a la estructura y contenido del resumen, con un exceso de resúmenes indicativos más que informativos. A partir de estos resultados concluimos que hace falta unificar criterios para una mejor redacción de los resúmenes de Enfermería y promoción de la investigación, con contenidos más afines a las directrices de la crítica especializada. Abstract in english The abstract is a genre that has received a great deal of attention in some areas, such as biomedicine and the social sciences (Salager-Meyer, 1990; Hyland, 2000; Swales & Feak, 2009); however, its structure and content in other areas, such as nursing, has received less attention. Its importance in [...] the dissemination of science should be an incentive for nursing authors to make it more informative and persuasive. No research has been found that surveyed the issue of whether the abstract should follow the traditional model of a single paragraph or structured with subtitles (Posteguillo Gomez & Piqué-Angordans, 2007). The aim of this study is to describe the content and structure of the traditional abstract, as well as its textual and discursive features. Drawing on the work of Weissberg and Buker (1990), we conducted an analysis of a corpus of 240 abstracts retrieved from twelve nursing journals in which we identified their structural units. One the most striking results was the wide range of variability in terms of the structure and content of the abstracts, with a vast majority of indicative, rather than informative abstracts. These findings suggest the need for a set of agreed upon criteria for writing abstracts in the field of nursing, more clearly aligned with international guidelines for scientific publication.

  16. Darwin's puzzling Expression.

    Science.gov (United States)

    Radick, Gregory

    2010-02-01

    Charles Darwin's The Expression of the Emotions in Man and Animals (1872) is a very different kind of work from On the Origin of Species (1859). This "otherness" is most extreme in the character of the explanations that Darwin offers in the Expression. Far from promoting his theory of natural selection, the Expression barely mentions that theory, instead drawing on explanatory principles which recall less Darwinian than Lamarckian and structuralist biological theorizing. Over the years, historians have offered a range of solutions to the puzzle of why the Expression is so "non-Darwinian". Close examination shows that none of these meets the case. However, recent research on Darwin's lifelong engagement with the controversies in his day over the unity of the human races makes possible a promising new solution. For Darwin, emotional expression served the cause of defending human unity precisely to the extent that natural selection theory did not apply. PMID:20338535

    Full Text Available Objective – To assess how the increase in number of electronic journals available to academic scholars has changed their information-seeking or consulting behaviour, with respect to 1 the amount and diversity of sources they read; 2 strategies they use to keep up-to-date in their fields; 3 use of personalized information services; 4 determining the value and relevance of articles; and 5 personal management of scientific information. This study is a follow-up to an earlier quantitative study (Borrego, Anglada, Barrios, & Comellas, 2007 in the same setting.Design – Qualitative, using an open-ended questionnaire, followed by personal interviews of a small group of the respondents.Setting – Universities that are members of the Consortium of Academic Libraries of Catalonia (CBUC, which is made up of the eight public Catalan universities and the National Library of Catalonia, Spain.Subjects – One hundred thirty-seven scholars from the member universities of diverse ages and disciplines. Eleven of these academics were selected for personal interviews.Methods – The authors used a two-staged approach to gather comments from researchers on their use of electronic journals. First, an open-ended, self-administered questionnaire (with some pre-testing donewas sent by e-mail to some 490 academics who had provided e-mail addresses in the quantitative study; 137 were returned and analyzed. Personal interviews were then conducted with 11 scholars who had given the most detailed answers in the questionnaire. Their ages ranged from 28 to 67; each was from a different discipline, and from six of the universities.Informed consent sheets (describing the study and guaranteeing anonymity were given to the 11 interviewees. Personal interviews were conducted in the subjects’ offices by one of the authors, and lasted between 45-60 minutes. In the interview stage, the authors wanted to examine: use and assessment of the library, access to electronic information, and impact of e-resources on information behaviour. Subjects were also asked to provide three suggestions on improving access to scientific information.Main Results – The amount of reading and number of electronic journals and other sources consulted among the scholars who participated in this study has increased. Three-quarters of survey respondents consult more journals and read more articles. The scholars reported that they are grateful for the increase in electronic information and its enhanced ease of access, and are not overwhelmed by it. Their reading has become more discriminatory, though, with many reporting “skimming” much of what they read to save time. Scholars keep up-to-date in three main ways: web browsing of journal issues, library database searches, and TOC e-mail alerts. More than 90% of survey respondents reported conducting database searches. Google and Google Scholar were often mentioned ahead of specific library database names. In determining value and relevance of an article, its author and abstract are key for scholars. In addition, personal information management techniques used by scholars were all over the board. The three main methods were use of print or electronic folders, reference management software, and no system. Many of the academics felt their information management systems were “rudimentary” (p. 225.The request for suggestions and comments on the questionnaire was not answered by “most of the sample” (p. 226. Those who did respond to this request asked for more library resources. The main complaint expressed by scholars concerned the difficulty and complexity of finding journal article content using the Library website (e.g., varying databases, difficulty of interpreting what journal electronic and print holdings are available. Because of this, a number of scholars used Google to find library-subscribed content.Conclusion – By having greater and easier access to e-journals, scholars accessing the CBUC read more articles from more disciplines. Scholars would prefer a simpler library interface to search for

  20. Expressive writing interventions in cancer patients: a systematic review.

    Science.gov (United States)

    Merz, Erin L; Fox, Rina S; Malcarne, Vanessa L

    2014-01-01

    Decades of research have suggested that expressive writing produces physical and psychological benefits in controlled laboratory experiments among healthy college students. This work has been extended to clinical and medical populations, including cancer patients. Although expressive writing could be a promising and inexpensive intervention for this population, the effects have not been systematically examined in oncology samples. A systematic review using PRISMA guidelines was conducted for experimental trials of cancer patients who participated in an expressive writing intervention. PsycINFO and PubMed/Medline were searched for peer-reviewed studies. Thirteen articles met the inclusion/exclusion criteria. Although the majority of the intervention effects were null, there were several main effects for expressive writing on sleep, pain, and general physical and psychological symptoms. Several moderators were identified, suggesting that expressive writing may be more or less beneficial based on individual characteristics such as social constraints. The reviewed studies were limited due to representativeness of the samples, performance, detection and patient-reported outcomes biases, and heterogeneity of the intervention protocol and writing prompts. Future studies with rigorous designs are needed to determine whether expressive writing is therapeutically effective in cancer patients. PMID:25053218

  14. Independence of face identity and expression processing: exploring the role of motion

    Science.gov (United States)

    Lander, Karen; Butcher, Natalie

    2015-01-01

    According to the classic Bruce and Young (1986) model of face recognition, identity and emotional expression information from the face are processed in parallel and independently. Since this functional model was published, a growing body of research has challenged this viewpoint and instead support an interdependence view. In addition, neural models of face processing emphasize differences in terms of the processing of changeable and invariant aspects of faces. This article provides a critical appraisal of this literature and discusses the role of motion in both expression and identity recognition and the intertwined nature of identity, expression and motion processing. We conclude by discussing recent advancements in this area and research questions that still need to be addressed. PMID:25821441

    2014-08-01

    Full Text Available Objective To observe the effect of Yangxueqingnao granules on c-Fos protein expression in trigeminal nucleus caudalis (TNC of nitroglycerin-induced migraine rats.  Methods A total of 108 healthy male Wistar rats were randomly divided into normal control group, model group, high-dose treatment group, low-dose treatment group, high-dose prevention and low-dose prevention group, and then each group was randomly divided into 3 subgroups: 30, 60 and 180 min group. The experimental migraine rat model was established by subcutaneous injection of nitroglycerin. The rats of normal control group were subcutaneously injected with saline solution of the same dosage. The rats of high- and low-dose treatment group were respectively administered with gastric perfusion of high- and low-dose Yangxueqingnao granules once 10 min after the modeling. The rats of high- and low- dose prevention group were respectively administered with gastric perfusion of high- and low- dose Yangxueqingnao granules for 7 d before the modeling. The rats were sacrificed and the brain tissues were collected at corresponding time points. Related behavior indexes of rats in each group were observed and recorded. TNC c-Fos protein expression changes were measured and compared among different groups.  Results At all time points, the c-Fos expression level of model group had no statistical difference from high- and low-dose treatment group (P > 0.05, for all. However, it was higher than that in high-dose prevention group (P = 0.031, 0.000, 0.000, while was only lower than that in low-dose prevention group at 60 and 180 min after modeling (P = 0.000, for all. There was statistical difference between high- and low-dose prevention group only at 30 min after modeling (P = 0.029. Conclusions The Yangxueqingnao granules can significantly decrease TNC c-Fos protein expression, which suggests that the preventive effect of Yangxueqingnao granules may be greater than the therapeutical effect on migraine. Its preventive effect may be associated with the decrease of TNC c-Fos protein expression. doi: 10.3969/j.issn.1672-6731.2014.08.012

  5. 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 reivity 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.

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

    DEFF Research Database (Denmark)

    Hatch, Mary Jo

    2012-01-01

    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

  11. Gene expression

    International Nuclear Information System (INIS)

    We prepared probes for isolating functional pieces of the metallothionein locus. The probes enabled a variety of experiments, eventually revealing two mechanisms for metallothionein gene expression, the order of the DNA coding units at the locus, and the location of the gene site in its chromosome. Once the switch regulating metallothionein synthesis was located, it could be joined by recombinant DNA methods to other, unrelated genes, then reintroduced into cells by gene-transfer techniques. The expression of these recombinant genes could then be induced by exposing the cells to Zn2+ or Cd2+. We would thus take advantage of the clearly defined switching properties of the metallothionein gene to manipulate the expression of other, perhaps normally constitutive, genes. Already, despite an incomplete understanding of how the regulatory switch of the metallothionein locus operates, such experiments have been performed successfully

Nevertheless, it is said that one of the causes that harmful rumor had spread was due to mass communication media. In the press reports on some nuclear power station when affected by an earthquake and on trouble in the nuclear power station in the future, we will propose that the publication should be really useful for habitants and citizens and be promoted in the positive and expected direction, in order not to make the same mistake as this time.

  5. Animal research

    DEFF Research Database (Denmark)

    Olsson, I.A.S.; SandØe, Peter

    2012-01-01

    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.

    Full Text Available [...] Abstract in english The welfare of research participants must be guaranteed by international ethical standards. This article communicates the procedures of the Research Ethics Committee of the School of Medicine, University of Chile (CEISH). The new Chilean legislation on research in human beings is also discussed. Law [...] 20.120: "On scientific research in human beings, its genome and forbidding human cloning" establishes the ethical principles that must be accomplished in every research involving human beings. Article 28 of the Law 20.584 "Regulation of the rights and duties of health care users", forbids the participation of handicapped people who cannot express their will in scientific research. Article 13 states that people not related directly with patient care cannot have access to his clinical records (with the exception of people with notarial authorization by the patient). CEISH proposes that, in case of people with intellectual deficiency, the decision to approve a scientific research should be analyzed on an individual basis. If the person is capable of expressing his or her will or has stated his or her consent beforehand, the research can be authorized. If the person cannot express his or her will, the scientific research cannot take place. In prospective studies, a consent from the patient and an authorization of the health authority should be required to access clinical records. In retrospective studies, consent should be obtained from the patient when personal information is going to be used. If the information is nameless, the consent can be disregarded.

    A neutron-absorbing article suitable for use in spent fuel racks is described. It comprises boron carbide particles, diluent particles, and a phenolic polymer cured to a continuous matrix. The diluent may be silicon carbide, graphite, amorphous carbon, alumina, or silica. The combined boron carbide-diluent phase contains no more than 2 percent B2O3, and the neutron-absorbing article contains from 20 to 40 percent phenol resin. The ratio of boron carbide to diluent particles is in the range 1:9 to 9:1

  12. Genome-wide in silico prediction of gene expression

    Motivation: Modelling the regulation of gene expression can provide insight into the regulatory roles of individual transcription factors (TFs) and histone modifications. Recently, Ouyang et al. in 2009 modelled gene expression levels in mouse embryonic stem (mES) cells using in vivo ChIP-seq measurements of TF binding. ChIP-seq TF binding data, however, are tissue-specific and relatively difficult to obtain. This limits the applicability of gene expression models that rely on ChIP-seq TF binding data. Results: In this study, we build regression-based models that relate gene expression to the binding of 12 different TFs, 7 histone modifications and chromatin accessibility (DNase I hypersensitivity) in two different tissues. We find that expression models based on computationally predicted TF binding can achieve similar accuracy to those using in vivo TF binding data and that including binding at weak sites is critical for accurate prediction of gene expression. We also find that incorporating histone modification and chromatin accessibility data results in additional accuracy. Surprisingly, we find that models that use no TF binding data at all, but only histone modification and chromatin accessibility data, can be as (or more) accurate than those based on in vivo TF binding data.

  14. Research by design - a research strategy

    DEFF Research Database (Denmark)

    Hauberg, JØrgen

    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 research – research based design. But can research arise from design?

  15. Facial Asymmetry and Emotional Expression

    CERN Document Server

    Pickin, Andrew

    2011-01-01

    This report is about facial asymmetry, its connection to emotional expression, and methods of measuring facial asymmetry in videos of faces. The research was motivated by two factors: firstly, there was a real opportunity to develop a novel measure of asymmetry that required minimal human involvement and that improved on earlier measures in the literature; and secondly, the study of the relationship between facial asymmetry and emotional expression is both interesting in its own right, and important because it can inform neuropsychological theory and answer open questions concerning emotional processing in the brain. The two aims of the research were: first, to develop an automatic frame-by-frame measure of facial asymmetry in videos of faces that improved on previous measures; and second, to use the measure to analyse the relationship between facial asymmetry and emotional expression, and connect our findings with previous research of the relationship.

  3. The aesthetic rationality of the popular expressive arts: Lifeworld communication among breast cancer survivors living with lymphedema

    Science.gov (United States)

    Quinlan, Elizabeth; Thomas, Roanne; Ahmed, Shahid; Fichtner, Pam; McMullen, Linda; Block, Janice

    2014-01-01

    The use of popular expressive arts as antidotes to the pathologies of the parallel processes of lifeworld colonization and cultural impoverishment has been under-theorized. This article enters the void with a project in which breast cancer survivors used collages and installations of everyday objects to solicit their authentic expression of the psycho-social impacts of lymphedema. The article enlists Jurgen Habermas' communicative action theory to explore the potential of these expressive arts to expand participants' meaningful engagement with their lifeworlds. The findings point to the unique non-linguistic discursivity of these non-institutional artistic forms as their liberating power to disclose silenced human needs: the images ‘spoke' for themselves for group members to recognize shared subjectivities. The authenticity claims inherent in the art forms fostered collective reflexivity and spontaneous, affective responses and compelled the group to create new collective understandings of the experience of living with lymphedema. The article contributes theoretical insights regarding the emancipatory potential of aesthetic-expressive rationality, an under-developed area of Habermasian theory of communicative action, and to the burgeoning literature on arts-based methods in social scientific research.

    Microarrays are made it possible to simultaneously monitor the expression profiles of thousands of genes under various experimental conditions. Identification of co-expressed genes and coherent patterns is the central goal in microarray or gene expression data analysis and is an important task in Bioinformatics research. In this paper, K-Means algorithm hybridised with Cluster Centre Initialization Algorithm (CCIA) is proposed Gene Expression Data. The proposed algorithm overcomes the drawbacks of specifying the number of clusters in the K-Means methods. Experimental analysis shows that the proposed method performs well on gene Expression Data when compare with the traditional K- Means clustering and Silhouette Coefficients cluster measure.

    Objectives A bibliometric analysis of the UK National Institute for Health Research (NIHR) Health Technology Assessment (HTA) monographs and their related journal articles by: (1) exploring the differences in citations to the HTA monographs in Google Scholar (GS), Scopus and Web of Science (WoS), and (2) comparing Scopus citations to the monographs with their related journal articles. Setting A study of 111 HTA monographs published in 2010 and 2011, and their external journal articles. Main outcome measures Citations to the monographs in GS, Scopus and WoS, and to their external journal articles in Scopus. Results The number of citations varied among the three databases, with GS having the highest and WoS the lowest; however, the citation-based rankings among the databases were highly correlated. Overall, 56% of monographs had a related publication, with the highest proportion for primary research (76%) and lowest for evidence syntheses (43%). There was a large variation in how the monographs were cited, compared to journal articles, resulting in more frequent problems, with unlinked citations in Scopus and WoS. When comparing differences in the number of citations between monograph publications with their related journal articles from the same project, we found that monographs received more citations than their journal articles for evidence syntheses and methodology projects; by contrast, journal articles related to primary research monographs were more highly cited than their monograph. Conclusions The numbers of citations to the HTA monographs differed considerably between the databases, but were highly correlated. When a HTA monograph had a journal article from the same study, there were more citations to the journal article for primary research, but more to the monographs for evidence syntheses. Citations to the related journal articles were more reliably recorded than citations to the HTA monographs. PMID:25694457

    To advance in their strategies to manage patients, clinicians need new research results. To be accessible, medical research must be published. Writing and publishing medical articles should respect principles that are described in this article. Good writing is based on a logical organization and the application of scientific style. Organization according to the IMRD structure (Introduction, Methods, Results, Discussion) allows one to present the reasons for and objectives of the study (Introduction), details on whatever has been done to answer the question (Methods), data on the actual study population and answers to the main question (Results), and a critical appraisal of these results, given the limits of the study and current knowledge (Discussion). The main elements of scientific style are precision, clarity, fluidity and concision. Finally, submitting a paper to a scientific journal implies presenting the work in a covering letter and respecting rules for formatting a manuscript (order of presentation, typography, etc.).

    Substantial theoretical and empirical focus has been placed on detailing the processes that therapists use in psychotherapy. Relatively limited investigation, however, has been conducted into the utility of the various techniques and processes that supervisors use in facilitating the development of trainee competence to conduct psychotherapy. The present article explores 2 sets of supervisory techniques/processes that can be used to assist novice therapists in the development of clinical skills from a supportive-expressive (Luborsky, 1984) relational (Greenberg & Mitchell, 1983) psychodynamic approach: (a) providing systematic and structured training in interpretation, and (b) facilitating trainee use of countertransference. We detail the theoretical underpinnings and research findings for each supervisory process, followed by presentation of vignettes illustrating supervisor-supervisee interactions that demonstrate the use of these processes.

    In the last decade or so, advances in genome-scale technologies have allowed systematic and detailed analysis of gene function. The experimental accessibility of budding yeast makes it a test-bed for technology development and application of new functional genomic tools and resources that pave the way for comparable efforts in higher eukaryotes. In this article, we review advances in reporter screening technology to discover trans-acting regulators of promoters (or cis-elements) of interest in the context of a novel functional genomics approach called Reporter Synthetic Genetic Array (R-SGA) analysis. We anticipate that this methodology will enable researchers to collect quantitative data on hundreds of gene expression pathways in an effort to better understand transcriptional regulatory networks.

    Recent years have witnessed a new round of research on one of the most studied proteins - myoglobin (Mb), the oxygen (O2) carrier of skeletal and heart muscle. Two major discoveries have stimulated research in this field: 1) that Mb has additional protecting functions, such as the regulation of in vivo levels of the signaling molecule nitric oxide (NO) by scavenging and generating NO during normoxia and hypoxia, respectively; and 2) that Mb in vertebrates (particularly fish) is expressed as tissue-specific isoforms in other tissues than heart and skeletal muscle, such as vessel endothelium, liver and brain, as found in cyprinid fish. Furthermore, Mb has also been found to protect against oxidative stress after hypoxia and reoxygenation and to undergo allosteric, O2-linked S-nitrosation, as in rainbow trout. Overall, the emerging evidence, particularly from fish species, indicates that Mb fulfills a broader array of physiological functions in a wider range of different tissues than hitherto appreciated. This new knowledge helps to better understand how variations in Mb structure and function may correlate with differences in animals' lifestyles and hypoxia-tolerance. This review integrates old and new results on Mb expression patterns and functional properties amongst vertebrates and discusses how these may relate to adaptive variations in different species.

    Recent advances in the field of neuroscience have dramatically changed our understanding of brain-behavior relationships. In this article, we illustrate how neuroscience can provide a conceptual and methodological framework to understand our clients within a transdiagnostic developmental perspective. We provide directions for integrating neuroscience into future process and outcome research. We present examples on how neuroscience can be integrated into researching the effects of contextual counseling interventions. We posit that interpersonal and environmental factors, such as neurotoxic factors (e.g., emotional neglect, stress), positive neurodevelopmental factors (e.g., nurturing and caring, environmental enrichment), and therapeutic interventions influence psychological processes (executive control, behavioral flexibility, reinforcement learning and approach motivation, emotional expression and regulation, self-representation and theory of mind). These psychological processes influence brain networks (attention, motivational, emotional regulation, social cognition), which influence cognitive, social, emotional, identity, and vocational development.

    Full Text Available The present paper analyses different approaches of religiosity in the psychological researches. We intend to explain the concept of religiosity, the distinction in the psychology field between religiosity and spirituality, religiosity dimensions and the main issues to be taken into account in measuring religiosity. In the analysis of the religiosity dimensions we refer to the hierarchical model of religiosity organization (Tsang and McCullough, 2003, which argues that religiosity is manifested at two levels: the dispositional level, reflecting the interindividual differences on religious features and the operational level, which refers to the interindividual diversity in the expression of religiosity. Regarding the measurement of religiosity, we analyze the conceptual clarity of the measured dimensions, the psychometric aspects of the religiosity measurement instruments, the sample representativeness and the cultural sensitivity of the instruments measuring religiosity. Throughout the article we present the results of some researches on the implications of the religiosity dimensions on the personal and family mental health

    2012-12-01

    In recent years, facial expression recognition (FER) has become an attractive research area, which besides the fundamental challenges, it poses, finds application in areas, such as human-computer interaction, clinical psychology, lie detection, pain assessment, and neurology. Generally the approaches to FER consist of three main steps: face detection, feature extraction and expression recognition. The recognition accuracy of FER hinges immensely on the relevance of the selected features in representing the target expressions. In this article, we present a person and gender independent 3D facial expression recognition method, using maximum relevance minimum redundancy geometrical features. The aim is to detect a compact set of features that sufficiently represents the most discriminative features between the target classes. Multi-class one-against-one SVM classifier was employed to recognize the seven facial expressions; neutral, happy, sad, angry, fear, disgust, and surprise. The average recognition accuracy of 92.2% was recorded. Furthermore, inter database homogeneity was investigated between two independent databases the BU-3DFE and UPM-3DFE the results showed a strong homogeneity between the two databases.

  13. Compound facial expressions of emotion.

    Du, Shichuan; Tao, Yong; Martinez, Aleix M

    2014-04-15

    Understanding the different categories of facial expressions of emotion regularly used by us is essential to gain insights into human cognition and affect as well as for the design of computational models and perceptual interfaces. Past research on facial expressions of emotion has focused on the study of six basic categories--happiness, surprise, anger, sadness, fear, and disgust. However, many more facial expressions of emotion exist and are used regularly by humans. This paper describes an important group of expressions, which we call compound emotion categories. Compound emotions are those that can be constructed by combining basic component categories to create new ones. For instance, happily surprised and angrily surprised are two distinct compound emotion categories. The present work defines 21 distinct emotion categories. Sample images of their facial expressions were collected from 230 human subjects. A Facial Action Coding System analysis shows the production of these 21 categories is different but consistent with the subordinate categories they represent (e.g., a happily surprised expression combines muscle movements observed in happiness and surprised). We show that these differences are sufficient to distinguish between the 21 defined categories. We then use a computational model of face perception to demonstrate that most of these categories are also visually discriminable from one another. PMID:24706770

    Alan Rose (University of California Davis; Molecular and Cellular Biology REV)

    2007-05-22

    Whereas many important biological discoveries have been made using plants, subsequent progress in some areas of plant research has fallen behind that in other organisms for which funding and in vitro assays are more readily available. Gene expression is one such field in which importance continues to grow because many potential plant biotechnology–based solutions to global problems depend on regulating the expression of specific genes. Previous limitations to exploring gene expression in plants have been partially mitigated by recent advances in genomics, genetics, and transformation techniques. The book Regulation of Gene Expression in Plants: The Role of Transcript Structure and Processing, edited by Carole L. Bassett, summarizes our current understanding of plant gene expression, with an emphasis on transcriptional and posttranscriptional regulation. The topics covered in six chapters include differences in messenger RNA (mRNA) structure caused by variations in transcription start and polyadenylation sites, alternative splicing, regulation by small RNAs, and mRNA transport and degradation. The chapters vary in depth, quality, and the degree to which the emphasis is placed on plants rather than eukaryotes in general. However, this slim volume is a useful review of gene expression in plants. The question of whether or not all differences in mRNA structure have functional importance remains open.

    2015-01-01

    Full Text Available Canada recognizes young people’s constitutionally protected freedom of expression and consequently their right to engage in a narrow subset of consensual sexually expressive practices without being prosecuted as child pornographers. Nevertheless, numerous anti-sexting campaigns decry the possibility of voluntary and “safe sexting” let alone the affordances of adolescents’ self-produced and consensually shared sexual imagery. In this article, we argue that these actors have erred in their construction of youths’ risqué imagery as inherently risky and thus governable. We propose that anti-sexting frameworks—which conflate consensual and nonconsensual sexting and which equate both with negative risks that purportedly outweigh the value and benefits of the practice—rely on a calculus that is fundamentally flawed. This article consists of two main parts. In Part I, we map and trouble the ways in which responses to consensual teenage sexting emphasize the practice’s relationship to embodied, financial, intimate and legal risks. In Part II, we suggest that research examining consensual adolescent sexting and young people’s rights to freedom of expression consider alternative theoretical frameworks, such as queer theories of temporality, when calculating the risk of harm of adolescent sexual imagery.

In the academic world, epistemic claims are associated with specific contents that an author makes when writing a research article. While there are diverse methods for analyzing the collective construction of knowledge, [...] there are no specific proposals to describe how these claims are socially inserted in the scientific community. In this context, the article presents an interdisciplinary method for studying how authors of scientific articles use their epistemic claims in order to insert themselves into a scientific community. We propose a typology of epistemic claims in which, based on the type of content they promote, we distinguish the theoretical and performance claims. The results show that the type of epistemic claim is associated with the citation strategy. The method that we propose contributes to the study of collective construction of knowledge, in that it makes it possible to differentiate the academic strategies used by authors and the type of knowledge claimed.

  1. “It Ain’t Shit About the Music!” : Discussions on Freedom of Expression in Relation to Rap Music in Social Work

    DEFF Research Database (Denmark)

    Ringsager, Kristine

    2015-01-01

    Based on field research among participants and employees at a series of rap projects, this article examines the use of rap music in social integration work among ethnic mi- nority youth from the perspective of anthropology of music. By highlighting the spe- cific discursive formations around the expediency of the production of rap music as a non-formal educational resource, the article focuses on the personal, political and social aspects of freedom of speech and the ways in which these are negotiated by re- pressive tolerance within the projects. On this background, it is discussed how the so- cio-economic aims of the rap-as-resource industry affect the participants’ expressions, and it is questioned whether the musical and personal agencies that are ideally offered by the projects are consistent with the actual freedom of action and expression that becomes available to the participants.

  10. Recognizing Facial Expressions Automatically from Video

    Science.gov (United States)

    Shan, Caifeng; Braspenning, Ralph

    Facial expressions, resulting from movements of the facial muscles, are the face changes in response to a person's internal emotional states, intentions, or social communications. There is a considerable history associated with the study on facial expressions. Darwin [22] was the first to describe in details the specific facial expressions associated with emotions in animals and humans, who argued that all mammals show emotions reliably in their faces. Since that, facial expression analysis has been a area of great research interest for behavioral scientists [27]. Psychological studies [48, 3] suggest that facial expressions, as the main mode for nonverbal communication, play a vital role in human face-to-face communication. For illustration, we show some examples of facial expressions in Fig. 1.

  20. From Research Assistant to Professional Research Assistance: Research Consulting as a Form of Research Practice

    Directory of Open Access Journals (Sweden)

    Dawn E. Pollon

    2013-01-01

    Full Text Available Research assistantships have long been viewed as an extension of the formal education process, a form of apprenticeship, and a pathway into the professional practice of research in institutional settings. However, there are other contexts in which researchers practice research. This self-study documents the formative role research assistantships played in the authors’ development as professional research consultants. Four professional research consultants who held research assistant positions during their master’s and doctoral studies describe the contributions of their research assistantship experiences to the advancement of their knowledge, skills, and passion for research and subsequently to their career decisions. Professional research consulting is identified as a natural extension of research assistant roles and a potential career path. The article enhances current understandings about the ways research assistantships contribute to the development of researchers, and specifically to the development of professional research consultants. The analysis will be of interest to students contemplating entering into research assistantships, current research assistants, current research assistant supervisors, academic staff looking to improve their research productivity, and department chairs.

    2011-08-01

    Full Text Available Abstract Background As whole genome and transcriptome sequencing gets cheaper and faster, a great number of 'exotic' animal models are emerging, rapidly adding valuable data to the ever-expanding Evo-Devo field. All these new organisms serve as a fantastic resource for the research community, but the sheer amount of data, some published, some not, makes detailed comparison of gene expression patterns very difficult to summarize - a problem sometimes even noticeable within a single lab. The need to merge existing data with new information in an organized manner that is publicly available to the research community is now more necessary than ever. Description In order to offer a homogenous way of storing and handling gene expression patterns from a variety of organisms, we have developed the first web-based comparative gene expression database for invertebrates that allows species-specific as well as cross-species gene expression comparisons. The database can be queried by gene name, developmental stage and/or expression domains. Conclusions This database provides a unique tool for the Evo-Devo research community that allows the retrieval, analysis and comparison of gene expression patterns within or among species. In addition, this database enables a quick identification of putative syn-expression groups that can be used to initiate, among other things, gene regulatory network (GRN projects.

  14. Beyond differential expression: the quest for causal mutations and effector molecules

    Directory of Open Access Journals (Sweden)

    Hudson Nicholas J

    2012-07-01

    Full Text Available Abstract High throughput gene expression technologies are a popular choice for researchers seeking molecular or systems-level explanations of biological phenomena. Nevertheless, there has been a groundswell of opinion that these approaches have not lived up to the hype because the interpretation of the data has lagged behind its generation. In our view a major problem has been an over-reliance on isolated lists of differentially expressed (DE genes which – by simply comparing genes to themselves – have the pitfall of taking molecular information out of context. Numerous scientists have emphasised the need for better context. This can be achieved through holistic measurements of differential connectivity in addition to, or in replacement, of DE. However, many scientists continue to use isolated lists of DE genes as the major source of input data for common readily available analytical tools. Focussing this opinion article on our own research in skeletal muscle, we outline our resolutions to these problems – particularly a universally powerful way of quantifying differential connectivity. With a well designed experiment, it is now possible to use gene expression to identify causal mutations and the other major effector molecules with whom they cooperate, irrespective of whether they themselves are DE. We explain why, for various reasons, no other currently available experimental techniques or quantitative analyses are capable of reaching these conclusions.

  16. Socializing infants towards a cultural understanding of expressing negative affect : A Bakhtinian informed discursive psychology approach

    DEFF Research Database (Denmark)

    Demuth, Carolin

    2013-01-01

    This article addresses the socialization of emotion expression in infancy. It argues that in order to adequately understand emotion development we need to consider the appraisal of emotion expression through caregivers in mundane, everyday interactions. Drawing on sociocultural and Bakhtinian theorizing, it claims that caregivers’ appraisals of infants’ emotion expression are dialogically intertwined with broader speech genres or “communicative genres” of a community and the emotional-volitional tone and normative orientations embedded in them. It aims to investigate how communicative genres become visible in early caregiver–infant interactions. In a comparative study with 20 farming Cameroonian Nso mothers from Kikaikelaki and 20 German middle-class mothers from Muenster and their 3-month-old infants, we investigated discursive practices used by the mothers in reaction to the infants’ expression of negative affect. We found distinct patterns of coconstructing the interaction that point to different normative ori- entations and communicative genres that can be considered to be specific to the two sociocultural contexts. These communicative genres were found to be in line with broader cultural ethnotheories on good child care in these two communities found in previous studies and by other researchers.

  17. Phosphoproteomics and Lung Cancer Research

    Directory of Open Access Journals (Sweden)

    William C. S. Cho

    2012-09-01

    Full Text Available Massive evidence suggests that genetic abnormalities contribute to the development of lung cancer. These molecular abnormalities may serve as diagnostic, prognostic and predictive biomarkers for this deadly disease. It is imperative to search these biomarkers in different tumorigenesis pathways so as to provide the most appropriate therapy for each individual patient with lung malignancy. Phosphoproteomics is a promising technology for the identification of biomarkers and novel therapeutic targets for cancer. Thousands of proteins interact via physical and chemical association. Moreover, some proteins can covalently modify other proteins post-translationally. These post-translational modifications ultimately give rise to the emergent functions of cells in sequence, space and time. Phosphoproteomics clinical researches imply the comprehensive analysis of the proteins that are expressed in cells or tissues and can be employed at different stages. In addition, understanding the functions of phosphorylated proteins requires the study of proteomes as linked systems rather than collections of individual protein molecules. In fact, proteomics approaches coupled with affinity chromatography strategies followed by mass spectrometry have been used to elucidate relevant biological questions. This article will discuss the relevant clues of post-translational modifications, phosphorylated proteins, and useful proteomics approaches to identify molecular cancer signatures. The recent progress in phosphoproteomics research in lung cancer will be also discussed.

    2005-05-01

    Full Text Available Abstract Background Airway smooth muscle cells play a key role in remodeling that contributes to airway hyperreactivity. Airway smooth muscle remodeling includes hypertrophy and hyperplasia. It has been previously shown that the expression of CD23 on ASMC in rabbits can be induced by the IgE component of the atopic serum. We examined if other components of atopic serum are capable of inducing CD23 expression independent of IgE. Methods Serum starved huASMC were stimulated with either IL-4, GM-CSF, IL-13, IL-5, PGD2, LTD4, tryptase or a combination of IL-4, IL-5, IL-13 each with GM-CSF for a period of 24 h. CD23 expression was analyzed by flow cytometry, western blot, and indirect immunofluorescence. Results The CD23 protein expression was upregulated in huASMC in response to IL-4, GM-CSF, and IL-4/GM-CSF. The percentage of cells with increased fluorescence intensity above the control was 25.1 ± 4.2% (IL-4, 15.6 ± 2.7% (GM-CSF and 32.9 ± 13.9% (IL-4/GMCSF combination(n = 3. The protein content of IL-4/GMCSF stimulated cells was significantly elevated. Expression of CD23 in response to IL-4, GM-CSF, IL-4/GM-CSF was accompanied by changes in cell morphology including depolymerization of isoactin fibers, cell spreading, and membrane ruffling. Western blot revealed abundant expression of the IL-4R? and a low level expression of IL-2R?c in huASMC. Stimulation with IL-4 resulted in the phosphorylation of STAT-6 and an increase in the expression of the IL-2R?c. Conclusion CD23 on huASMC is upregulated by IL-4, GM-CSF, and IL-4/GM-CSF. The expression of CD23 is accompanied by an increase in cell volume and an increase in protein content per cell, suggesting hypertrophy. Upregulation of CD23 by IL-4/GM-CSF results in phenotypic changes in huASMC that could play a role in cell migration or a change in the synthetic function of the cells. Upregulation of CD23 in huASMC by IL-4 and GM-CSF can contribute to changes in huASMC and may provide an avenue for new therapeutic options in asthma targeting ASMC.

    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.

    2015-03-01

    Full Text Available Facial expression recognition is one of the most active fields of research. Many facial expression recognition methods have been developed and implemented. Neural networks (NNs have capability to undertake such pattern recognition tasks. The key factor of the use of NN is based on its characteristics. It is capable in conducting learning and generalizing, non-linear mapping, and parallel computation. Backpropagation neural networks (BPNNs are the approach methods that mostly used. In this study, BPNNs were used as classifier to categorize facial expression images into seven-class of expressions which are anger, disgust, fear, happiness, sadness, neutral and surprise. For the purpose of feature extraction tasks, three discrete wavelet transforms were used to decompose images, namely Haar wavelet, Daubechies (4 wavelet and Coiflet (1 wavelet. To analyze the proposed method, a facial expression recognition system was built. The proposed method was tested on static images from JAFFE database.

  1. In plants, expression breadth and expression level distinctly and non-linearly correlate with gene structure

    Directory of Open Access Journals (Sweden)

    Yang Hangxing

    2009-11-01

    Full Text Available Abstract Background Compactness of highly/broadly expressed genes in human has been explained as selection for efficiency, regional mutation biases or genomic design. However, highly expressed genes in flowering plants were shown to be less compact than lowly expressed ones. On the other hand, opposite facts have also been documented that pollen-expressed Arabidopsis genes tend to contain shorter introns and highly expressed moss genes are compact. This issue is important because it provides a chance to compare the selectionism and the neutralism views about genome evolution. Furthermore, this issue also helps to understand the fates of introns, from the angle of gene expression. Results In this study, I used expression data covering more tissues and employ new analytical methods to reexamine the correlations between gene expression and gene structure for two flowering plants, Arabidopsis thaliana and Oryza sativa. It is shown that, different aspects of expression pattern correlate with different parts of gene sequences in distinct ways. In detail, expression level is significantly negatively correlated with gene size, especially the size of non-coding regions, whereas expression breadth correlates with non-coding structural parameters positively and with coding region parameters negatively. Furthermore, the relationships between expression level and structural parameters seem to be non-linear, with the extremes of structural parameters possibly scale as power-laws or logrithmic functions of expression levels. Conclusion In plants, highly expressed genes are compact, especially in the non-coding regions. Broadly expressed genes tend to contain longer non-coding sequences, which may be necessary for complex regulations. In combination with previous studies about other plants and about animals, some common scenarios about the correlation between gene expression and gene structure begin to emerge. Based on the functional relationships between extreme values of structural characteristics and expression level, an effort was made to evaluate the relative effectiveness of the energy-cost hypothesis and the time-cost hypothesis.

    Liisa Husu

    2010-03-01

    Full Text Available Gender patterns in technological and engineering research careers were explored in a EU funded 13-country study PROMETEA, conducted 2005-2007, including old and new EU member states, as well as Serbia, Russia and Chile. Drawing on the data from this study, the article analyses the gendering of key arenas of excellence in technological and engineering research from a comparative international perspective, with focus on research funding, publishing, scientific prizes and awards, and patents. A central challenge for gender-sensitive science and research policy is how to combine the promotion of scientific excellence with the promotion of gender equality. Exploring gendering of excellence in technology and engineering research is of especial interest because of the strong position this field enjoys in European research policy and in national research policies, and because it continues to be the most male-dominated research field in Europe. The article also discusses methodological challenges of this type of international research.

  3. Mars Express wins unanimous support

    "The green light for Mars Express shows that Europe is perfectly capable of seizing special chances in exploring space," said Roger Bonnet, ESA's director of science. "At a cost to ESA of 150 million ECU, Mars Express is the cheapest Mars mission ever, yet its importance and originality are far greater than the price tag suggests." Bonnet continued: "Mars Express has been advertised by the Science Programme Committee as a test case for new approaches in procuring and managing future science projects, with a view to achieving major savings. In the international arena, Mars Express will confirm Europe's interest in a major target for space research in the new century, when we make our forceful debut at the Red Planet. In fact, Mars Express is designed to be a pivotal element of an international multi-mission, global effort for the exploration of Mars." Development of the spacecraft will now proceed swiftly, to meet the deadline of an exceptionally favourable launch window early in June 2003. Mars Express will go into orbit around Mars at Christmas 2003. Seven scientific instruments on board will include a high-resolution camera, a range of spectrometers, and a radar to penetrate below the surface. For the first time in the history of the exploration of the Red Planet, scientists can hope to detect sub-surface water, whether it exists in the form of undergound rivers, pools, glaciers or permafrost. Signs of life on Mars, whether extinct or continuing today, may reveal themselves to a lander carried by Mars Express. This is Beagle 2, a project led by the Open University in the United Kingdom, with contributions from many other European countries. The lander also promises invaluable information about the chemistry of the Martian surface and atmosphere. Beagle 2 is to be independently funded. Some of the necessary funds have already been raised and ESA has agreed with the principal investigator to keep a place for Beagle 2 aboard Mars Express. The financial situation will be verified at a date to be agreed with the mission's prime contractor.

  4. Protein Expression-Yeast

    DEFF Research Database (Denmark)

    Nielsen, Klaus Hvid

    2014-01-01

    Yeast is an excellent system for the expression of recombinant eukaryotic proteins. Both endogenous and heterologous proteins can be overexpressed in yeast (Phan et al., 2001; Ton and Rao, 2004). Because yeast is easy to manipulate genetically, a strain can be optimized for the expression of a specific protein. Many eukaryotic proteins contain posttranslational modifications that can be performed in yeast but not in bacterial expression systems. In comparison with mammalian cell culture expression systems, growing yeast is both faster and less expensive, and large-scale cultures can be performed using fermentation. While several different yeast expression systems exist, this chapter focuses on the budding yeast Saccharomyces cerevisiae and will briefly describe some options to consider when selecting vectors and tags to be used for protein expression. Throughout this chapter, the expression and purification of yeast elF3 is shown as an example alongside a general scheme outline.

    Full Text Available 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.

  10. THE IMPLEMENTATION OF FINDINGS PUBLISHED IN SCHOLARLY ARTICLES

    Directory of Open Access Journals (Sweden)

    Martin A. Hubbe

    2010-07-01

    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.

    2015-01-01

    Background Given the variation in human papillomavirus (HPV) vaccine coverage across Canada, and debate regarding delivery of HPV vaccines in Catholic schools, we studied online comments on Canadian news websites to understand public perceptions of HPV and HPV vaccine. Methods We searched English- and French-language Canadian news websites for 2012 articles that contained the terms “HPV” or “human papillomavirus.” Articles about HPV vaccinations that contained at least one comment were included. Two researchers independently coded comments, analyzing them for emerging themes. Results We identified 3073 comments from 1198 individuals in response to 71 news articles; 630 (52.6%) individuals expressed positive sentiments about HPV vaccination (2.5 comments/individual), 404 (33.7%) were negative (3.0 comments/individual), 34 (2.8%) were mixed (1.5 comments/individual) and 130 (10.8%) were neutral (1.6 comments/individual). Vaccine-supportive commenters believed the vaccine is safe and effective. Common themes in negative comments included concerns regarding HPV vaccine safety and efficacy, distrust of pharmaceutical companies and government, and belief that school-age children are too young for HPV vaccine. Many comments focused on whether the Catholic Church has the right to inform health policy for students, and discussion often evolved into debates regarding HPV and sexual behaviour. We noted that many individuals doubted the credibility of vaccine safety information. Conclusion The majority of commenters do not appear to be against HPV vaccination, but public health messaging that focuses on both the vaccine’s safety profile, and its use as a means to prevent cancer rather than sexually transmitted HPV infection may facilitate its acceptance.

  1. Extending the boundaries of research on adolescent development.

    The mainstream psychology literature has historically failed to include individuals with nonheterosexual sexual orientations in its study of many areas, including adolescent development, sexual development, psychotherapy, couple relationships, aging, suicide, and substance abuse. The articles contained in this issue make clear that knowledge of human behavior will be more complete when research designs are expanded to reflect more accurately the diversity of sexual orientations and sexual expressions. Furthermore, when sexuality is categorized into a rigidly defined group like lesbian, gay, bisexual, and transgender (LGBT), it constrains the ways in which individuals might otherwise think about it. Knowledge of human behavior will be advanced more effectively when the field of psychology integrates people of diverse and complex sexualities into its research and studies the mediators and moderators associated with this diversity.

    2008-01-01

    In this didactic paper, I review some prevalent “myths” about clinical research: anyone can do research; you can learn how to do research from a book or journal articles; all you need to do statistics is the right software (although Excel will also do); you can do good quality research at your kitchen sink; what is important is that you did your best. These myths appear particularly prevalent in the complementary and alternative medicine communities. They are based on a clear double stand...

    2012-01-01

    Virtual environments allow human beings to be represented by virtual humans or avatars. Users can share a sense of virtual presence is the avatar looks like the real human it represents. This classically involves turning the avatar into a clone with the real human's appearance and voice. However, the possibility of cloning the gesture expressivity of a real person has received little attention so far. Gesture expressivity combines the style and mood of a person. Expressivity parameters have b...
