This paper investigates how boosters are used by qualitative and quantitative research article writers to express certainty. Boosters are words such as "definitely," "sure," "demonstrate" which signal writers' assurance in what they say. Drawing on a corpus of 200 research articles in Applied Linguistics, this

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.
This article presents a group of lexical bundles identified in a corpus of research article introductions as the first step in the analysis of these expressions in the different sections of the research article.

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.

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.

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.

Introduction: The number of citations an article receives is an important indication of its impact and its contribution to academia. There is a paucity of literature concerning top article citations in diabetes. The main objective of this investigation was to bridge this gap and to provide readers with a practical guide in evaluating diabetes literature. Methods: Scopus Library was searched to determine the citations of all published diabetes articles. A total of 100 articles were included in our investigation under the subject category Diabetes, diabetes mellitus, and diabetics. Two databases were used to extract citations. We did not apply any time restriction in our search. The top 100 cited articles were selected and analyzed by two independent investigators. We extracted immediacy index from ResearchGate. Results: The journal with the highest number of top 100 cited articles was The New England Journal of Medicine with 23, followed by 22 in Diabetes Care. The top article on the list received 17,779 citations. A statistically significant association was found between the journal impact factor and the number of top 100 cited articles (p < 0.005). The United States had the highest number of articles (59). Contrary to bibliometric analyses published in other medical fields, the largest subset of the diabetes articles (n = 54) were published in the 10-year period between 2000 and 2009. Conclusion: Our analysis provides an insight on the citation frequency of top cited articles published in diabetes to help recognize the quality of the works, discoveries and the trends steering the study of diabetes.

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.

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 todays 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.

By that way, express enterprises can identify the value-added parts from the whole process of mails or goods from senders to receivers, and all these parts will lead to logistics value added. Based on value chain analysis, a model of logistics competitiveness is established. The model includes four aspects: location, network optimization / integration, value-added services / response and performance measures, which form the core competitiveness for express enterprises.

Policies ensuring that research data are available on public archives are increasingly being implemented at the government , 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 , 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...

Over the past decade, a handful of key developments have caused scholars and researchers to rethink not only the way they conduct their work, but also the way in which they communicate it to others. The advent of the Internet has provided unprecedented opportunities for immediate, cost effective global connectivity, opening up new possibilities for collaboration and communication. This has resulted in scholarship increasingly being conducted in the online environment, and a vast amount of new digital information being generated and made widely available to those interested in using it. Additionally, the Internet is a dynamic environment, with new channels for producing and sharing information in a myriad of formats emerging frequently.In higher education, the momentum of the burgeoning movement towards "open" sharing of information of all kinds continues to gain traction. In particular, advancements in the areas of opening up access to articles and reserch data are increasingly visible. In both of these areas, academic and research libraries are playing important, central roles in promoting the awareness of the potential costs and benefits of a more open research environment, as well as defining new roles for libraries in this digital environment.As this push for grater openness continues, these fronts are intersecting in interesting and potentially transformative ways. The Open Access and Open Data movements share fundamental philosophical commonalities that make collaboration a natural outcome. Both movements place a premium on reducing barriers to discovering and accessing pertinent digital information. Perhaps even more significantly, both explicitly recognize that enabling productive use of digital information is key to unlocking its full value. As a result of these shared priorities, there are a wide variety of common strategies that libraries can take to help advance research, presenting new opportunities for deeper collaboration to take place.This talk will explore what is happening in these "open" movements from both a practical and policy standpoint; how this might directly impact academia, the research community, and especially, libraries.

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.

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.

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.

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.

Objectives We investigated how often journal articles reporting on human HIV research in four developing world countries mention any institutional review boards (IRBs) or research ethics committees (RECs), and what factors are involved. Methods We examined all such articles published in 2007 from India, Nigeria, Thailand and Uganda, and coded these for several ethical and other characteristics. Results Of 221 articles meeting inclusion criteria, 32.1% did not mention IRB approval. Mention of IRB approval was associated with: biomedical (versus psychosocial) research (P=0.001), more sponsor-country authors (P=0.003), sponsor-country corresponding author (P=0.047), mention of funding (P<0.001), particular host-country involved (P=0.002), journals having sponsor-country editors (P<0.001), and journal stated compliance with International Committee of Medical Journal Editors (ICMJE) (P=0. 003). Logistic regression identified 3 significant factors: mention of funding, journal having sponsor-country editors and research being biomedical. Conclusions One-third of articles still do not mention IRB approval. Mention varied by country, and was associated with biomedical research, and more sponsor country involvement. Recently, some journals have required mention of IRB approval, but allow authors to do so in cover letters to editors, not in the article itself. Instead, these data suggest, journals should require that articles document adherence to ethical standards. PMID:21794072

Full Text Available It is imperative to study demographic factors while studying buying behavior of customers as demographic factors are the major determinants of buying behavior. To verify the green buying behavior of customers and to evaluate the influence of demographic factors on green buying behavior, researchers have critically analyzed, research articles, research papers and research reports of this aspect. The review found thirty three articles that studied demographic factors from various perspectives of green buying behavior. Review has been presented in the synthesized format. Studying the relationship between impacts of demographic parameters on green buying behaviour has seen three major results. Few researchers conclude to have significant relationship between demographic parameters and green buying behaviour. Few researchers outcome is against this. Some researchers arouse controversial findings stating different demographic parameters has different role to play in the determination of green buying behavior.

Full Text Available Reading research articles in English will be a special challenge for those students who speak English as a foreign language (EFL. EFL graduate students will require a specific method for helping them to cope with the articles they have to read. This study tries to offer a method for helping them to read, understand, and analyze English articles easier. This study employs evaluation and trialing. It is accompanied by pre and post surveys that will give information about the condition of the students before and after the method is implemented. This study involved graduate students majoring in Information Systems at Satya Wacana Christian University. It is expected that the method proposed will help the students to know exactly what they need to read and focus on when they read a research article so that they can use their time more efficiently and effectively.

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

In this paper, we outline a method that teaches students how to study research literature. The method aids in developing a student's confidence by posing a simple set of steps with questions. The method has been used successfully for developing literature skills with high-school, undergraduate and graduate students in U.S. engineering curriculum. The method, which has the Japanese name, KENSHU, was developed by modifying a system used at a top Japanese national university. KENSHU is Japanese for research understanding. The basic steps of KENSHU are: (i) take a recent foreign (English) scientific article and divide it into sections, (ii) read and discuss a single section with a more experienced classmate, (iii) translate the section, (iv) continue step iii until all sections are finished, (iv) prepare a one page summary of the article with key graphs and tables, and (v) present the findings of the article at a miniconference. In this work, we have put into words, the aspects of reading a scientific article that incorporates the KENSHU framework. We applied the method to U.S. university juniors and seniors, graduate students as well as junior and senior high-school students. We conclude that the method is effective for not only learning how to read scientific articles, but also for learning how to write scientific articles.

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
OBJECTIVES: English has become the most frequently used language for scientific communication in the biomedical field. Therefore, scholars from all over the world try to publish their findings in English. This trend has a number of advantages, along with several disadvantages. METHODS: In the current article, the most important disadvantages of publishing biomedical research articles in English for non-native speakers of English are reviewed. RESULTS: The most important disadvantages of publishing biomedical research articles in English for non-native speakers may include: Overlooking, either unintentionally or even deliberately, the most important local health problems; failure to carry out groundbreaking research due to limited medical research budgets; violating generally accepted codes of publication ethics and committing research misconduct and publications in open-access scam/predatory journals rather than prestigious journals. CONCLUSIONS: The above mentioned disadvantages could eventually result in academic establishments becoming irresponsible or, even worse, corrupt. In order to avoid this, scientists, scientific organizations, academic institutions, and scientific associations all over the world should design and implement a wider range of collaborative and comprehensive plans.

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 authors 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 This paper describes a corpus-based analysis of the distribution of the high-frequency collocates of abstract nouns in 320 research articles across eight disciplines: Chemistry, Computer Science, Materials Science, Neuroscience, Economics, Language and Linguistics, Management, and Psychology. Disciplinary variation was also examined very little previous research seems to have investigated this. The corpus was analysed using WordSmith Tools. The 16 highest-frequency nouns across all eight disciplines were identified, followed by the highest-frequency collocates for each noun. Five disciplines showed over 50% variance from the overall results. Conclusions are that the differing patterns revealed are disciplinary norms and represent standard terminology within the disciplines arising from the topics discussed, research methods, and content of discussions. It is also concluded that the collocations are an important part of the meanings and functions of the nouns, and that this evidence of sharp discipline differences underlines the importance of discipline-specific collocation research.
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.

The inner ear is a highly specialized mechanosensitive organ responsible for hearing and balance. Its small size and difficulty in harvesting sufficient tissue has hindered the progress of molecular studies. The protein components of mechanotransduction, the molecular biology of inner ear development and the genetic causes of many hereditary hearing and balance disorders remain largely unknown. Inner-ear gene expression data will help illuminate each of these areas. For over a decade, our laboratories and others have generated extensive sets of gene expression data for different cell types in the inner ear using various sample preparation methods and high-throughput genome-wide approaches. To facilitate the study of genes in the inner ear by efficient presentation of the accumulated data and to foster collaboration among investigators, we have developed the Shared Harvard Inner Ear Laboratory Database (SHIELD), an integrated resource that seeks to compile, organize and analyse the genomic, transcriptomic and proteomic knowledge of the inner ear. Five datasets are currently available. These datasets are combined in a relational database that integrates experimental data and annotations relevant to the inner ear. The SHIELD has a searchable web interface with two data retrieval options: viewing the gene pages online or downloading individual datasets as data tables. Each retrieved gene page shows the gene expression data and detailed gene information with hyperlinks to other online databases with up-to-date annotations. Downloadable data tables, for more convenient offline data analysis, are derived from publications and are current as of the time of publication. The SHIELD has made published and some unpublished data freely available to the public with the hope and expectation of accelerating discovery in the molecular biology of balance, hearing and deafness.

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.

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.

The NASA Langley Research Center uses more than 10000 strain gages per year in supporting its various research programs. The character of the testing at LaRC is such that the types of strain gage installations, the materials they are applied to, and the test environments encountered, require many varied approaches for installing strain gages. These installations must be accomplished in the most technically discerning and appropriate manner. This technical memorandum is offered as an assisting guide in helping the strain gage user to determine the appropriate approach for a given strain gage application requirement. Specifically, this document offers detailed recommendations for strain gaging the following: LaRC-Designed balances, LARC custom transducers, certain composite materials and alloys, high-temperature test articles, and selected non-typical or unique materials or test conditions.

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 Projects (PKP Open Journal Systems (OJS, developed by Stanford University and Simon Fraser University; and Harvard Universitys 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 David E Vance,1 Michele Talley,1 Andres Azuero,1 Patricia F Pearce,2 Becky J Christian1 1School of Nursing, University of Alabama at Birmingham, Birmingham, AL, USA; 2Loyola University School of Nursing, New Orleans, LA, USA Abstract: The ability to critically evaluate the merits of a quantitative design research article is a necessary skill for practitioners and researchers of all disciplines, including nursing, in order to judge the integrity and usefulness of the evidence and conclusions made in an article. 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 In todays 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 ones 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.

This article presents research-based examples of effective instructional approaches for improving the quality of the content of stories and essays written by students with learning disabilities. We also describe recent research on handwriting and spelling (transcription skills) and show how instruction in these areas affects overall writing quality. Examples of instructional approaches that improve writing quality are taken from experimental studies included in a recent meta-analysis by Gersten and Baker (2001) conducted on writing intervention research. A common goal in these studies was to teach students with learning disabilities how to organize writing tasks, generate ideas about the writing topics, and produce final written products that were coherent and organized. In this article, our goal is to illustrate how findings from these studies can be implemented in both general and special education settings. PMID:15493427

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.

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

Full Text Available The 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.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.

Full Text Available This paper reports on an experience carried out with second course students of the School of Aeronautical Engineers at the Polytechnic University of Madrid in the subject class Modern Technical Language. In the previous years the problem in that class had been the scarce participation of the students in the oral practices. They seemed to be lead and exclusively represented by a few students when it came to oral participation. The students proposed tackling recent research articles in which opinions could be discussed. The reading of these articles has risen new elements that work as language activators in the language classroom: critical reading and thinking have developed participation in the oral activities and produced a noticeable influence on their scientific and humanist thinking and behavior.From this, we may extract the consequence that the experience is not only related to scientific knowledge, since it has made them better speakers or speaking-counterparts and more class-participating and collaborative, which implies that the human, scientific and linguistic factors progress at the same time through the critical experience. This way, the exposition of their critical ideas has developed both their humanism and scientific mind. These two facets which seem to belong to far away fields become a bond in our experience: the process is scientific since it tries to be a systematic study of the knowledge fleshed in written texts and it is also humanist because it fulfils the students need to grow up as persons, that is absorbing knowledge and processing it in order to produce a new personal approach to the world.

Full Text Available Aim and Objective: Quality of methodological and statistical parameters published in various Indian Medical Journals are usually debated in terms of appropriateness. Aim of this manuscript is to analyze and validate efficacy studies on antidepressant drugs published in Indian Medical Journals regarding quality of various methodological and statistical parameters used. Materials and Methods: An in-depth review of Efficacy studies on Antidepressant published in Indian Medical Journals was conducted. Articles were retrieved from all possible sources like Published Journals, downloaded through Pubmed, MedInd, Opengate, Medknow, and Cochrane. These studies were analyzed and validated for various methodological and statistical parameters. Descriptive statistics for various parameters with confidence interval (CI is also reported herewith. Results : Of 32 articles reviewed, primary and secondary endpoints and sample size calculation was reported in only one article (3.1%; 95% CI, 0.5 to 15.7%. Power and CI was not reported in any of the reviewed articles. Inclusion and exclusion criteria were reported in 9 (28.3%; 95% CI, 15.5 to 45.3% articles. Information regarding randomization was mentioned in 12 (37.5%; 95% CI, 22.9 to 54.7% articles, whereas reporting of blinding or open label status of the study was mentioned in 21 (65.6%; 95% CI, 48.3 to 79.5% articles. Assumptions of statistical tests were not reported in any of the reviewed articles. Statistical tests were used in only 14 (43.7%; 95% CI, 28.1 to 60.6% articles of which 70% of were inappropriate. All studies were underpowered for small and medium effect size. Conclusion: Quality of reporting of methodological and statistical aspects of antidepressant efficacy studies published in Indian medical journals are poor and hence makes difficult to conclude on issues related to validity of these studies.

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.

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

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

The past 25 years have served as a test bed for exploring the chemistry and physics, in general, and the electron transfer chemistry, in particular, of low-dimensional carbon. Nevertheless, the new realm started with the advent of fullerenes, followed in chronological order by carbon nanotubes, and, more recently, by graphene. The major thrust of this Review article is to historically recap the versatility of fullerenes regarding the design, the synthesis, and the tests as an electroactive building block in photosynthetic reaction mimics, photovoltaics, and catalysis.

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.

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 studys objective is discuss some of the possible contributions from Schützs 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 peoples descriptions. Alfred Scützs 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.

Terahertz (THz) imaging and sensing technologies are increasingly being used in a host of medical, military, and security applications. For example, THz systems are now being tested at international airports for security screening purposes, at major medical centers for cancer and burn diagnosis, and at border patrol checkpoints for identification of concealed explosives, drugs, and weapons. Recent advances in THz applications have stimulated renewed interest regarding the biological effects associated with this frequency range. Biological effects studies are a valuable type of basic science research because they serve to enhance our fundamental understanding of the mechanisms that govern THz interactions with biological systems. Such studies are also important because they often times lay the foundation for the development of future applications. In addition, from a practical standpoint, THz biological effects research is also necessary for accurate health hazard evaluation, the development of empirically-based safety standards, and for the safe use of THz systems. Given the importance and timeliness of THz bioeffects data, the purpose of this review is twofold. First, to provide readers with a common reference, which contains the necessary background concepts in biophysics and THz technology, that are required to both conduct and evaluate THz biological research. Second, to provide a critical review of the scientific literature.

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

"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.

The Phillips Laboratory at the Edwards Air Force Base has developed the Advanced Space Structures Technology Research Experiment (ASTREX) facility to serve as a testbed for demonstrating the applicability of proven theories to the challenges of spacecraft maneuvers and structural control. This report describes the work performed on the ASTREX test article by Texas A&M University under contract NAS119373 as a part of the Control-Structure Interaction (CSI) Guest Investigator Program. The focus of this work is on maneuvering the ASTREX test article with compressed air thrusters that can be throttled, while attenuating structural excitation. The theoretical foundation for designing the near minimum-time thrust commands is based on the generation of smooth, parameterized optimal open-loop control profiles, and the determination of control laws for final position regulation and tracking using Lyapunov stability theory. Details of the theory, mathematical modeling, model updating, and compensation for the presence of 'real world' effects are described and the experimental results are presented. The results show an excellent match between theory and experiments.
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. Hylands 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.
It is widely recognised that public acceptability often poses a barrier towards renewable energy development. This article reviews existing research on public perceptions of wind energy, where opposition is typically characterized by the NIMBY (not in my back yard) concept. The objectives of the article are to provide a critical assessment of past research and an integrated, multidimensional framework to guide future work. Six distinct strands of research are identified, summarized and critiqued: public support for switching from conventional energy sources to wind energy; aspects of turbines associated with negative perceptions; the impact of physical proximity to turbines; acceptance over time of wind farms; NIMBYism as an explanation for negative perceptions; and, finally, the impact of local involvement on perceptions. Research across these strands is characterized by opinion poll studies of general beliefs and case studies of perceptions of specific developments. In both cases, research is fragmented and has failed to adequately explain, rather than merely describe, perceptual processes. The article argues for more theoretically informed empirical research, grounded in social science concepts and methods. A multidimensional framework is proposed that goes beyond the NIMBY label and integrates previous findings with social and environmental psychological theory. Copyright
Full Text Available To determine the issue of whether there were any significant differences between the groups including Iran ISI, Iran non- ISI, and native authors in binary comparisons as for employing interactional markers, the present study was conducted. To collect the data, 90 'method sections' of English medical research articles within Iranian ISI, Iranian non- ISI, and native ISI journals written by Iranian and native authors published between 2005 and 2010, were examined. As the model of analysis, Hyland's (2005 taxonomy of metadiscourse markers was used. After performing quantitative and qualitative analyses of the interactional markers, Chi- Square tests were run. The results of the study at p= 0.05 revealed significant differences in binary comparisons made up of native / Iran ISI, native / Iran non- ISI, and Iran ISI/ Iran non-ISI as for employing self-mentions. The findings also demonstrated a significant difference between Native and Iran ISI groups for using boosters. These differences may be influenced by the writers' mother tongue, culture and also by their lack or limited awareness of the rhetorical conventions of English medical academic research writing which are needed to be taken into consideration.

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

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 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.

Objective: To study the expression and distribution of the haptoglobin in the bone marrow of irradiated mice and explore the relationship between haptoglobin and cell cycle or apoptosis. Methods: RT-PCR and Western blot were adopted to respectively detect the changes of the haptoglobin at mRNA and protein levels. Flow cytometry (FCM) was applied to analyze the relation between cytoplasmic haptoglobin existence in bone marrow and cell cycle or apoptosis. Results: The results showed that increased levels of haptoglobin mRNA and protein were present after irradiation. Results of FCM indicated there was difference in cell cycle between the cells with and without haptoglobin protein. Conclusion: Haptoglobin might be involved in the repair process of radiation injury. (authors)
The genetic engineering system, clustered regularly interspaced short palindromic repeats (CRISPR), has conventionally been used to inactivate genes by making targeted double stranded cuts in DNA. While CRISPR is a useful tool, it can only be used to create loss-of-function modifications and often causes off-target effects due to the disruptive mechanism by which it works. CTD2 researchers at the University of California, San Francisco recently addressed these shortcomings in a publication in Cell.

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.
This article proposes to establish and critique connections between religious and musico-aesthetic conceptions of in-effability by exploring the link between neoplatonic thought and romantic aesthetics. The central thesis is that recourse to the ineffable is often made by resorting to theological tenets and, consequently, that romantic aesthetics, although desperately trying to disengage itself from theological thinking, can in fact be interpreted as being inextricably bound up with it.

The aim of this paper is to understand whether the probability of receiving positive peer reviews is influenced by having published in an independently assessed, high-ranking journal: we eventually interpret a positive relationship among peer evaluation and journal ranking as evidence that journal ratings are good predictors of article quality. The analysis is based on a large dataset of over 11,500 research articles published in Italy in the period 2004-2010 in the areas of architecture, arts and humanities, history and philosophy, law, sociology and political sciences. These articles received a score by a large number of externally appointed referees in the context of the Italian research assessment exercise (VQR); similarly, journal scores were assigned in a panel-based independent assessment, which involved all academic journals in which Italian scholars have published, carried out under a different procedure. The score of an article is compared with that of the journal it is published in: more specifically, we first estimate an ordered probit model, assessing the probability for a paper of receiving a higher score, the higher the score of the journal; in a second step, we concentrate on the top papers, evaluating the probability of a paper receiving an excellent score having been published in a top-rated journal. In doing so, we control for a number of characteristics of the paper and its author, including the language of publication, the scientific field and its size, the age of the author and the academic status. We add to the literature on journal classification by providing for the first time a large scale test of the robustness of expert-based classification. PMID:26309731

Since the early 1970s the Institute for Technical Physics of the Research Center Karlsruhe has been involved in the development of superconductivity for research and industrial applications. A broad program with a focus on the superconducting magnet technology was established to include large magnets for nuclear fusion, high-field magnets for nuclear magnetic resonance spectrometers, ore separation and energy storage magnets. Research and development work was performed in collaborative projects with other national as well as international institutions and industry. The success of these projects has been supported by a broad foundation of engineering science in superconductor development, electrical and cryogenic engineering. Several well known test facilities like TOSKA, STAR, HOMER, MTA along with well equipped laboratories for conductor development, materials at cryogenic temperatures, cryogenic high-voltage engineering have made substantial contributions to in-house, national and international projects. A strong cryogenic infrastructure with two refrigerators and sophisticated cooling circuits from about 4.5 K down to 1.8 K assure the reliable operation of these large facilities. Last but not least, cryogenic research, including vacuum pumps for International Thermonuclear Experimental Reactor, improvements in thermal insulation, cryogenic instrumentation and small on board refrigerators has supported progress in this field. High-temperature superconductivity projects for low AC loss conductors, a 70 kA current lead and a fault current limiter are currently in progress.

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

Cyberpsychology is a recently emergent field that examines the impact of technology upon human cognition and behavior. Given its infancy, authors have rapidly created new measures to gauge their constructs of interest. Unfortunately, few of these authors have had the opportunity to test their scales' psychometric properties and validity. This is concerning, as many theoretical assumptions may be founded upon scales with inadequate attributes. If this were found to be true, then previous findings in cyberpsychology studies would need to be retested, and future research would need to shift its focus to creating psychometrically sound and valid measures. To provide inferences on this concern, the current study examines the article reporting, scale creation, and scale reliabilities of every article published in Cyberpsychology, Behavior, and Social Networking from its inception to July 2014. The final data set encompassed the coding of 1,478 individual articles, including 921 scales, and spanning 17 years. The results demonstrate that the simple survey methodology has become more popular over time. Authors are gradually applying empirically tested scales. However, self-created measures are still the most popular, leading to concerns about the measures' validity. Also, the use of multi-item measures has increased over time, but many articles still fail to report adequate information to assess the reliability of the applied scales. Lastly, the average scale reliability is 0.81, which barely meets standard cutoffs. Overall, these results are not overly concerning, but suggestions are given on methods to improve the reporting of measures, the creation of scales, and the state of cyberpsychology. PMID:25751050

The articles are categorized according to their object and methodological approach, as well as their theoretical foundations through the study of citations. Throughout this investigation, we point out the most expressive and active authors in the field of knowledge organization in Brazil. We also identify the journals that are more devoted to the theme and we conclude that Brazilian scientific production on the theme is irregularly distributed over the period of time analyzed, peaking in 2011 when 18,27% of the total number of articles were published. We conclude by establishing the relationship between theoretical currents of knowledge organization and the prevalent approaches and themes found in the corpus. The focus of the most prevalent research approaches were the theoretical and linguistic approaches and the type of analysis was documentary.

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 Aspergers 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-Childrens 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

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.
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)
The aims and goals of this study have been to find out how native speakers of Norwegian and learners of English as a foreign language express gratitude in certain situations. Based on the impression that Norwegians may appear impolite to people from other cultures, I hypothesised that this might be related to how Norwegians express gratitude in English, i.e. that they do not adjust to the sociopragmatic and pragmalinguistic norms of English, but simply transfer their L1 strategies.

Summary: Images containing spatial expression patterns illuminate the roles of different genes during embryogenesis. In order to generate initial clues to regulatory interactions, biologists frequently need to know the set of genes expressed at the same time at specific locations in a developing embryo, as well as related research publications. However, text-based mining of image annotations and research articles cannot produce all relevant results, because the primary data are images that ex...

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.

Too Few Articles in the Journal Literature on Instruction in Academic Libraries are Research?Based. A review of: Crawford, Gregory A., and Jessica Feldt. An Analysis of the Literature on Instruction in Academic Libraries. Reference & User Services Quarterly 46.3 (Spr. 2007: 77?87.
Full Text Available Objective To discover which journals publish a preponderance of the literature on instruction in academic libraries, and to further learn what topics are discussed in the literature and what methods of inquiry are used to explore those topics.Design Comparative analysis.Setting The ERIC database.Subjects Journal articles published between 1971 and 2002, found in the ERIC database via the descriptor library instruction.Methods Journal articles published between 1971 and 2002 were searched in the ERIC database using the term library instruction, because the term has been used by ERIC since the inception of the database. Article characteristics such as year of publication, journal in which a given article was published, and types of articles were identified. After normalizing the identification of article types by comparing individual codifications of a random sample of articles from the results list, the researchers coded all of the articles according to the articles main topics. These article topics were then condensed into broader topics (e.g. articles coded initially as addressing the topics of instruction to graduate students or high school students were condensed under the heading instruction of specific populations. Those articles deemed to have a research component were further analyzed in terms of research methodology, scope, and use of statistics. The questions guiding the authors? study consisted of: In which journals are articles on instruction in academic libraries published? What are the topics of the articles that have been published? How has the literature of instruction in academic libraries changed over the years? What is the nature of research [authors? emphasis] articles on instruction in academic libraries? For research articles, what are the research methods used and what types of statistics are utilized? (77?78.Main results The search found 791 articles appearing in 90 journals. However, only six journals were responsible for publishing 60% of the articles on the results list. Based on the categorization into topics or types,five article types general essays, articles on instruction for searching online catalogs and databases, articles on course? or assignment?related instruction, programmatic and management issues,and specific institution instruction accounted for 54% of the total articles; eleven other topics are represented in the remaining articles. Only 24.5% of the articles could be considered research?based. While nine types of research methods were used, 62.3% of the research?based articles relied on surveys or questionnaires. However, taking into account what could be an expected decline in interest for studying instruction for microforms, and an increased interest in studying instruction for the Internet, the types of articles published each year between 1971 and 2002 remained generally static.Conclusion The authors conclude that, unsurprisingly, a select few journals are responsible for publishing the majority of articles on instruction in academic libraries, and note that these journals are closely associated with academic librarianship and instruction (85. The authors findings concerning the types of articles published over the course of the date range examined, although interesting, are equally unsurprising. What is surprising and alarming, is that only a quarter of all articles published are research-based. Furthermore, those articles that were found to be research-based did not often employ sophisticated research methods, preferring for example, the use of descriptive statistics over inferential statistics. Ideally, this article will spur the development and publication of more, and more rigorous, research?based scholarship in addition to pointing authors both to the journals most likely to publish their research and to the topics that have been historically (since 1971 underrepresented in the literature.

The human steroid receptor RNA activator (SRA) gene encodes both noncoding RNAs (ncRNAs) and protein-generating isoforms. In reporter assays, SRA ncRNA enhances nuclear receptor and myogenic differentiation 1 (MyoD)-mediated transcription but also participates in specific corepressor complexes, serving as a distinct scaffold. That SRA RNA levels might affect some biological functions, such as proliferation, apoptosis, steroidogenesis, and myogenesis, has been reported. However, the breadth of endogenous target genes that might be regulated by SRA RNAs remains largely unknown. To address this, we depleted SRA RNA in two human cancer cell lines with small interfering RNAs and then assayed for changes in gene expression by microarray analyses. The majority of significantly changed genes were reduced upon SRA knockdown, implicating SRA RNAs as endogenous coactivators. Unexpectedly, only a small subset of direct estrogen receptor-alpha target genes was affected in estradiol-treated MCF-7 cells. Eight bona fide SRA downstream target genes were identified (SLC2A3, SLC2A12, CCL20, TGFB2, DIO2, TMEM65, TBL1X, and TMPRSS2), representing entirely novel SRA targets, except for TMPRSS2. These data suggest unanticipated roles for SRA in glucose uptake, cellular signaling, T(3) hormone generation, and invasion/metastasis. SRA depletion in MDA-MB-231 cells reduced invasiveness and expression of some genes critical for this process. Consistent with the knockdown data, overexpressed SRA ncRNA coactivates certain target promoters and may enhance the activity of some coregulatory proteins. This study is a valuable resource because it represents the first genome-wide analysis of a mammalian RNA coregulator. PMID:20219889

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 spearhedsand 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 genetic engineering system, clustered regularly interspaced short palindromic repeats (CRISPR), has conventionally been used to inactivate genes by making targeted double stranded cuts in DNA. While CRISPR is a useful tool, it can only be used to create loss-of-function modifications and often causes off-target effects due to the disruptive mechanism by which it works. CTD2 researchers at the University of California, San Francisco recently addressed these shortcomings in a publication in Cell.

Skeletal system has two main functions, to provide mechanical integrity for both locomotion and protection and to play an important role in mineral homeostasis. There is extensive evidence showing loss of bone mass during long-term Space-Flights. The loss is due to a break in the equilibrium between the activity of osteoblasts (the cells that forms bone) and the activity of osteoclasts (the cells that resorbs bone). Surprisingly, there is scanty information about the possible altered gene expression occurring in cells that form bone in microgravity.(Just 69 articles result from a "gene expression in microgravity" MedLine query.) Gene-chip or microarray technology allows to screen thousands of genes at the same time: the use of this technology on samples coming from cells exposed to microgravity could provide us with many important informations. For example, the identification of the molecules or structures which are the first sensors of the mechanical stress derived from lack of gravity, could help in understanding which is the first event leading to bone loss due to long-term exposure to microgravity. Consequently, this structure could become a target for a custom-designed drug. It is evident that bone mass loss, observed during long-time stay in Space, represents an accelerated model of what happens in aging osteoporosis. Therefore, the discovery and design of drugs able to interfere with the bone-loss process, could help also in preventing negative physiological processes normally observed on Earth. Considering the aims stated above, my research is designed to:

Lysophosphatidic acid (LPA) is a lipid-derived signaling molecule that plays key roles in diverse biological processes including inflammation and uterine remodeling. Although the function of LPA and its receptors has been extensively studied using knock-out mice, the temporal-spatial expression of LPA receptors is less well-characterized. To gain further insight into the dynamic regulation of LPA receptor 3 (Lpar3) expression in vivo by bioluminescence imaging, we generated and characterized mice transgenic for a putative Lpar3 promoter fragment. A non-coding region of the Lpar3 gene immediately upstream of the start site was subcloned adjacent to the luciferase gene. Promoter activity was determined by in vitro luciferase assays, in vivo bioluminescent imaging or by semi-quantitative real-time PCR. The air-pouch model was used to investigate Lpar3 promoter activity in the context of inflammation. The putative Lpar3 promoter fragment behaved similarly to the endogenous promoter in vitro and in vivo. In male mice, elevated levels of Lpar3-induced luciferase activity were observed in the testis. In female mice, the basal level of luciferase activity in the uterus significantly increased during pseudopregnancy. Moreover, luciferase activity was upregulated by TNF-? in the air-pouch model. We report the identification of a functional Lpar3 promoter fragment and the generation of a transgenic mouse model to investigate the regulation of Lpar3 promoter activity non-invasively in vivo by bioluminescence imaging. This mouse model is a valuable tool for reproductive biology and inflammation research as well as other biological processes in which this receptor is involved. PMID:25982332

Full Text Available The aim of this paper is to understand whether the probability of receiving positive peer reviews is influenced by having published in an independently assessed, high-ranking journal: we eventually interpret a positive relationship among peer evaluation and journal ranking as evidence that journal ratings are good predictors of article quality. The analysis is based on a large dataset of over 11,500 research articles published in Italy in the period 2004-2010 in the areas of architecture, arts and humanities, history and philosophy, law, sociology and political sciences. These articles received a score by a large number of externally appointed referees in the context of the Italian research assessment exercise (VQR; similarly, journal scores were assigned in a panel-based independent assessment, which involved all academic journals in which Italian scholars have published, carried out under a different procedure. The score of an article is compared with that of the journal it is published in: more specifically, we first estimate an ordered probit model, assessing the probability for a paper of receiving a higher score, the higher the score of the journal; in a second step, we concentrate on the top papers, evaluating the probability of a paper receiving an excellent score having been published in a top-rated journal. In doing so, we control for a number of characteristics of the paper and its author, including the language of publication, the scientific field and its size, the age of the author and the academic status. We add to the literature on journal classification by providing for the first time a large scale test of the robustness of expert-based classification.

The character of force and strain measurement testing at LaRC is such that the types of strain gauge installations, the materials upon which the strain gauges are applied, and the test environments encountered, require many varied approaches. In 1997, a NASA Technical Memorandum (NASA TM 110327) was generated to provide the strain gauge application specialist with a listing of recommended procedures for strain gauging various transducers and test articles at LaRC. The technical memorandum offered here is an effort to keep the strain gauge user informed of new technological enhancements in strain-gauging methodology while preserving the strain-gauging guidelines set forth in the 1997 TM. This document provides detailed recommendations for strain gauging LaRC-designed balances and custom transducers, composite materials, cryogenic and high-temperature test articles, and selected non-typical or unique materials or test conditions. Additionally, one section offers details for installing Bragg-Grating type fiber-optic strain sensors for non-typical test scenarios.

Tracking Theory Building and Use Trends in Selected LIS Journals: More Research is Needed. A review of: Kim, Sung?Jin, and Dong Y. Jeong. An Analysis of the Development and Use of Theory in Library and Information Science Research Articles. Library & Information Science Research 28.4 (Sept. 2006: 548?62.
Full Text Available Objective ? The authors measure theory incidents occurring in four LIS journals between 1984?2003 in order to examine their number and quality and to analyze them by topic. A third objective, only identified later in the text of the study, was to compare theory development and use between Korean and international journals. Research questions asked include whether LIS has its own theoretical base as a discipline, and what characteristics the theoretical framework has.Design Bibliometric study.Setting Journal issues selected from four LIS journals for the time span from 1984 ? 2003.Subjects Two international journals, Journal of the American Society for Information Science and Technology (JASIST and Library and Information Science Research (LISR were selected based on their high ranking in the Social Sciences Citation Index (SSCI impact factors. Two Korean journals, Journal of the Korean Society for Information Management (JKSIM and Journal of the Korean Society for Library and Information Science (JKSLIS were selected.Methods ? After having determined a definition of theory, and identifying different levels of theory, the authors set up rules for the identification of theory incidents, which are defined as events in which the author contributed to the development or the use of theory in his/her own paper (550. Content analysis of 1661 research articles was performed to measure theory incidents according to working definitions. Interrater reliability was ensured by conducting independent coding for subfield classification, identification of theory incidents, and quality measurement (555,using a sample of 199 articles (random selection not specified, achieving 94?97% interrater reliability. Incidents, once identified, were evaluated for quality using Dubins 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.

This paper presents a study of the 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 recommendations offered.

Allport's (1954) contact hypothesis conditions in reducing prejudice. Methodological advances in the study of prejudice are reviewed, and implications of research findings for counselors are
Full Text Available The purpose of this research was to examine the validity of Lotka and Paos 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 Paos laws were tested using both Lotkas formula: (for Lotkas Law; also for testing Paos 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 Paos law was applicable to these subject areas. Survey both literature and original examining of Lotka and Paos Laws witnessed some aspects should be considered. The main elements involved in fitting in a bibliometrics method have been identified: using Lotka or Paos law, subject area, period of time, measurement of authors, and a criterion for assessing goodness-of-fit.
Full Text Available This contribution is based on the four presentations made at the Special Interest Group (SIG meeting titled Gene Expression in Fungi held during IMC9 in Edinburgh. This overview is independent from other articles published or that will be published by each speaker. In the SIG meeting, basic principles of in vivo animal models for virulence studies were discussed. Infection associated genes of Candida albicans and fungal adaptation to the host was summarized. Azole susceptibility was evaluated as a combined result of several changes in expression of pertinent genes. Gene transfer in fungi, resulting in fungal evolution and gene adaptation to environmental factors, was reported.

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 TVs 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.
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 Collagen, type III, alpha-1 (COL3A1 is essential for normal collagen I fibrillogenesis in many organs. There are differences in phenotypes of mutations in the COL3A1 gene in humans and mutations in mice. In order to investigate whether the regulation and gene network of COL3A1 is the same in healthy populations of mice and humans, we compared the quantitative trait loci (QTL that regulate the expression level of COL3A1 and the gene network of COL3A1 pathways between humans and mice using whole genome expression profiles. Our results showed that, for the regulation of expression of Col3a1 in mice, an eQTL on chromosome (Chr 12 regulates the expression of Col3a1. However, expression of genes in the syntenic region on human Chr 7 has no association with the expression level of COL3A1. For the gene network comparison, we identified 44 top genes whose expression levels are strongly associated with that of Col3a1 in mice. We next identified 41 genes strongly associated with the expression level of COL3A1 in humans. There are a few but significant differences in the COL3A1 gene network between humans and mice. Several genes showed opposite association with expression of COL3A1. These genes are known to play important roles in development and function of the extracellular matrix of the lung. Difference in the molecular pathway of key genes in the COL3A1 gene network in humans and mice suggest caution should be used in extrapolating results from models of human lung diseases in mice to clinical lung diseases in humans. These differences may influence the efficacy of drugs in humans whose development employed mouse models.

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

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.

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

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

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

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

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

After a launch from the Baikonur cosmodrome, Kazakhstan, 9 November 2005 and a five-month cruise, the Venus Express spacecraft reached Venus on 11 April 2006. The spacecraft has now reached its final operational, 24 hour polar orbit, with apocentre altitude of 66000km and pericentre altitude of 250 km. During the first weeks of routine operation the spacecraft has already sent back a wealth of exiting information. Venus is thus again, after having been the `"forgotten planet" for more than a decade, target for intense studies to better understand the many problems not answered by the more than twenty US and Soviet probes launched in the previous decades. The objective of the Venus Express mission is to carry out a comprehensive study of the atmosphere of Venus, the plasma environment and its interaction with the solar wind, and to study certain aspects of the surface of the planet. A well optimised payload composed of two multi channel spectrometers, an IR-Vis-UV imaging spectrometer, a wide angle camera, a multi-sensor energetic particle instrument, a magnetometer, and a radio science experiment, allows all elements of the objectives to be addressed at a sufficient depth. Venus Express has been developed in record time, less than four years, using an efficient concept of re-using elements of recently developed spacecraft, mainly Mars Express and Rosetta. Significant savings for both the space and ground segments have been possible by using existing teams in industry, in ESA and in several of the science institutes involved. The first data has shown a highly dynamic atmosphere, including close-ups of the southern polar double vortex, indeed topics of high interest and among the top priority objectives. The high resolution spectrometers are finding several minor species at various depths of the atmosphere. Venus Express is the first mission fully exploiting the Infrared spectral windows, in order to map the atmosphere in three dimensions. The first data returned from the mission promises an exiting time to come with analysis of very high quality data from state of the art instrumentation.

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

Full Text Available Abstract Background Nocturnal insects such as moths are ideal models to study the molecular bases of olfaction that they use, among examples, for the detection of mating partners and host plants. Knowing how an odour generates a neuronal signal in insect antennae is crucial for understanding the physiological bases of olfaction, and also could lead to the identification of original targets for the development of olfactory-based control strategies against herbivorous moth pests. Here, we describe an Expressed Sequence Tag (EST project to characterize the antennal transcriptome of the noctuid pest model, Spodoptera littoralis, and to identify candidate genes involved in odour/pheromone detection. Results By targeting cDNAs from male antennae, we biased gene discovery towards genes potentially involved in male olfaction, including pheromone reception. A total of 20760 ESTs were obtained from a normalized library and were assembled in 9033 unigenes. 6530 were annotated based on BLAST analyses and gene prediction software identified 6738 ORFs. The unigenes were compared to the Bombyx mori proteome and to ESTs derived from Lepidoptera transcriptome projects. We identified a large number of candidate genes involved in odour and pheromone detection and turnover, including 31 candidate chemosensory receptor genes, but also genes potentially involved in olfactory modulation. Conclusions Our project has generated a large collection of antennal transcripts from a Lepidoptera. The normalization process, allowing enrichment in low abundant genes, proved to be particularly relevant to identify chemosensory receptors in a species for which no genomic data are available. Our results also suggest that olfactory modulation can take place at the level of the antennae itself. These EST resources will be invaluable for exploring the mechanisms of olfaction and pheromone detection in S. littoralis, and for ultimately identifying original targets to fight against moth herbivorous pests.

Changing gene expression patterns is the essential driver of developmental processes. Growth factors, micro-RNAs, long intergenic noncoding RNAs, and epigenetic marks, such as DNA methylation and histone modifications, all work by impacting gene expression. The key features of developing cells, including their ability to communicate with others, are defined primarily by their gene-expression profiles. It is therefore clear that a gene-expression atlas of the developing kidney can provide a useful tool for the developmental nephrology research community. Toward this end, the GenitoUrinary Development Molecular Anatomy Project (GUDMAP) consortium has worked to create an atlas of the changing gene-expression patterns that drive kidney development. In this article, the global gene-expression profiling strategies of GUDMAP are reviewed. The initial work used laser-capture microdissection to purify multiple compartments of the developing kidney, including cap mesenchyme, renal vesicle, S-shaped bodies, proximal tubules, and more, which were then gene-expression profiled using microarrays. Resolution of the atlas was then improved by using transgenic mice with specific cell types labeled with green fluorescent protein (GFP), allowing their purification and profiling. In addition, RNA-Seq replaced microarrays. Currently, the atlas is being pushed to the single-cell resolution using microfluidic approaches that allow high-throughput RNA-Seq analysis of hundreds of individual cells. Results can identify novel types of cells and define interesting heterogeneities present within cell populations. PMID:23996451

This article is a primer on converting a dissertation based on qualitative research into a journal article. It summarizes seven
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.

One approach to research into the syntax of nominals focuses on parallels between nominals and clauses. Within the generative tradition, the structure of the left periphery of the clause has been well documented as a position for e.g. wh-words and topic and focus (see e.g Rizzi 1997), whereas the left periphery of the nominal has received much less attention. One of the more challenging areas of research within the nominal is the analysis of elements that can occur before the indefinite article, e.g. "such (a book)" and "so interesting (a book)". Another recently studied phenomenon, often taken to be linked to this, is indefinite determiner doubling, i.e. nominal expressions which appear to contain two instances of the indefinite article.

The Publications Committee is seeking volunteers to develop an electronic template for providing production-ready article files. The template would allow authors to create their accepted manuscripts in XML, the language used by AGU to produce online journals. If authors could use this template to produce XML files according to AGU specifications, in much the same way as they previously provided camera-ready copy, and the costs of article production could correspondingly be lowered, the savings could be passed on to authors. The Information Technology Committee will be advising the Publications Committee and staff throughout the experiment. Participants will use the AGU article DTD, which provides a detailed prescription for tagging all elements of a journal article. The challenge is to come up with a workable template that uses open source code to produce valid content files. The XML file is critical because it serves as the version of record of the article, as well as the underlying source for generating all representations of it; the XML also enables AGU to offer additional features that go beyond the printed page.
A neutron absorbing article, in flat plate form and suitable for use in a storage rack for spent fuel, includes boron carbide particles, diluent particles and a solid, irreversibly cured phenolic polymer cured to a continuous matrix binding the boron carbide and diluent particles. The total conent of boron carbide and diluent particles is a major proportion of the article and the content of cured phenolic polymer present is a minor proportion. By regulation of the ratio of boron carbide particles to diluent particles, normally within the range of 1:9 and 9:1 and preferably within the range of 1:5 to 5:1, the neutron absorbing activity of the product may be controlled, which facilitates the manufacture of articles of particular absorbing activities best suitable for specific applications

This paper describes in outline a method for translating Japanese temporal expressions into English. We argue that temporal expressions form a special subset of language that is best handled as a special module in machine translation. The paper deals with problems of lexical idiosyncrasy as well as the choice of articles and prepositions within temporal expressions. In addition temporal expressions are considered as parts of larger structures, and the question of whether to translate them as noun phrases or adverbials is addressed.

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.
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?

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.

Scientific research and the publication of the results of the studies go hand in hand. Exquisite research methods can only be adequately reflected in formal publication with the optimum structure. To ensure the success of this process, it is necessary to follow orderly steps, including selecting the journal in which to publish and following the instructions to authors strictly as well as the guidelines elaborated by diverse societies of editors and other institutions. It is also necessary to structure the contents of the article in a logical and attractive way and to use an accurate, clear, and concise style of language. Although not all the authors are directly involved in the actual writing, elaborating a scientific article is a collective undertaking that does not finish until the article is published. This article provides practical advice about formal and not-so-formal details to take into account when writing a scientific article as well as references that will help readers find more information in greater detail.

Por último, pretendo que el texto se convierta en un recurso didáctico que facilite la planificación de metodologías de integración curricular, entrelazando las artes plásticas a otros contenidos programáticos, situación que contribuye al logro de aprendizajes significativos y, en consecuencia, al desarrollo integral de la población estudiantil.Abstract: This article comes from a research work called La práctica pedagógica de la expresión artística en los niveles de VI y VII Nivel de la Educación General Básica (Pedagogic Practice of the Fine Arts in Levels VI and VII in General Basic Education, carried out in the Instituto de Investigación en Educación, INIE (Institute for Research on Education o f the University of Costa Rica, during the years 2006, 2007 and 2008. Voluntary primary and secondary school teachers, who wanted to add curriculum integration experiences to their labor, took part in this research. It also refers to the making of a pedagogic practice's foundations. The methodology was organized through 'phases' that allowed spaces for thought and favored the appraisal of the teachers' work from a qualitative perspective. Some curricular integration plans are included too; these plans arise from the experiences practiced by the school population. Finally, the author intends to make this text a teaching resource that helps to plan curricular integration methodologies while joining the fine arts to other program contents; which contributes to the achievement of significant learning, and therefore, to the integral development of the student population.

This report is made of two parts: the first part is a status report which highlights the main achievements of all research activities conducted in 2001 in the global context of national and international efforts on nuclear waste management (partitioning and transmutation, disposal in deep geological formations, conditioning and storage, national and international collaborations, report no 7 of the national review board (CNE), the Global 201 conference and the year 2001 highlights). The second part is the executive summary of the 2002 edition of the 'Research strategy and programmes' document. The new edition has ben reorganized according to previous editions in an effort to make it more concise, clearer and more comprehensive. Chapter 1 now focusses entirely on the methodology followed by all research partners and stakeholders in structuring and implementing research programmes. Chapter 2 is new and provides a summary of the major research results 10 years after the 1991 law became effective. Chapter 3 is also new and highlights the major milestones yet ahead and identified in terms of both objectives to be attained and key steps leading up to 2006. Chapter 4 contains a detailed description and analysis of the programmes envisaged and the last 2 chapters discuss very broadly the coordination of research activities and the way they are being implemented both at national (chapter 5) and international (chapter 6) levels.

Full Text Available This article presents a description of culinary terms in Russian and Norwegian, and deals with the contrastive study of metaphorical expressions containing such terms, making a special point of their origin, thematic variety and linguistic properties. The author argues that the universal character of metaphorical changes makes itself evident in a large number of expressions containing either verbs connected with cooking or naming products and dishes used as characteristics of a human being or human actions, great number of them being used pejoratively. The author argues that the study of the structure and semantics of these phraseological units can also be of great help in getting a better command of the culture and history of the country and its language.

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.

Humans are well adapted to quickly recognize and adequately respond to anothers emotions. Different theories propose that mimicry of emotional expressions (facial or otherwise) mechanistically underlies, or at least facilitates, these swift adaptive reactions. When people unconsciously mimic their interaction partners expressions of emotion, they come to feel reflections of those companions emotions, which in turn influence the observers own emotional and empathic behavior. The majority of research has focused on facial actions as expressions of emotion. However, the fact that emotions are not just expressed by facial muscles alone is often still ignored in emotion perception research. In this article, I therefore argue for a broader exploration of emotion signals from sources beyond the face muscles that are more automatic and difficult to control. Specifically, I will focus on the perception of implicit sources such as gaze and tears and autonomic responses such as pupil-dilation, eyeblinks and blushing that are subtle yet visible to observers and because they can hardly be controlled or regulated by the sender, provide important veridical information. Recently, more research is emerging about the mimicry of these subtle affective signals including pupil-mimicry. I will here review this literature and suggest avenues for future research that will eventually lead to a better comprehension of how these signals help in making social judgments and understand each others emotions.

Full Text Available Ana Clara P Azevedo-Pouly, Thomas D SchmittgenDivision of Pharmaceutics and Pharmaceutical Chemistry, the Ohio State University College of Pharmacy, Columbus, OH, USAAbstract: Since their discovery in mammals in 2001, the field of microRNA (miRNA research has grown exponentially. miRNAs regulate protein translation following binding to conserved sequences within the 3' untranslated region of messenger RNAs. miRNAs are found to regulate nearly all biological processes, and their expression has been shown to differentially regulate a large number of diseases including cancer. Pancreatic ductal adenocarcinoma (PDAC was one of the initial groups of cancers to demonstrate differential miRNA expression. Since then, there have been numerous studies linking differential miRNA expression to PDAC. Translational extrapolation of these studies has been done linking diagnostic, prognostic, and therapeutic applications, and multiple review articles and book chapters have been written on these subjects. The intent here is to provide an overview of pancreatic cancer and review the current state of the validated and published findings on the messenger RNA targets of differentially expressed miRNAs in PDAC. We then attempt to summarize these findings to extrapolate them in the hopes of better understanding how altered miRNA expression in PDAC may alter the phenotype of this disease.Keywords: microRNA, pancreatic cancer, pancreatic ductal adenocarcinoma, target

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.

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  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 . 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.
Full Text Available Introduction: The aim of this study is to investigate the process of rewriting medical research papers for the lay public. The latest findings of medical research often appear in the popular media. It is interesting to see what happens to a scientific text when it is transmitted to a new audience. Hedging is usually interpreted as a characteristic feature of scientific discourse. This study focuses on hedging, which also tends to be applied in popularized articles in the field of medicine.
This paper introduces a new memoized derivative parsing algorithm for recognition of parsing expression grammars. The algorithm runs in worst case quartic time and cubic space. However, existing research suggests that due to the limited amount of backtracking and recursion in real-world grammars and input, practical performance may be closer to linear time and constant space; experimental validation of this conjecture is in progress.

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.

In this study, the authors examined the scientific quality of health research reported in the three daily newspapers in Trinidad and Tobago. All medical research articles published for the period January 1 to December 31, 2003, were extracted using a standardized data collection form. The scientific quality of the articles was analyzed by taking into consideration various aspects of study design, as well as other issues associated with accurate reporting. Of the 321 eligible articles, 108 were collected from The Trinidad Express, 100 from The Trinidad Guardian and 113 from The Trinidad and Tobago Newsday. The percentages of articles reporting methodological components consistent with good scientific quality were as follows: objective(s) (99.7%), study design (79.8%), study procedure (70.1%), selection procedure (70.1%), description of participants (87.5%), control/matching group (74.9%), outcome variables (99.4%) and issues of validity and reliability (2.5%). In addition, the percentage of articles containing aspects of good report writing were as follows: authorship (71.3%), authors' affiliation (59.5%), location of the study (25.4%), source of the research material (83.1%), duration of the study (27.7%), study setting (72.0%), number of participants (74.1%), period in which the study was conducted (12.0%) and quantification of the results (66.7%). Observational studies were significantly more likely to be reported than experimental studies (71.5% versus 28.5%). Overall, articles reported in the Trinidad Express and the Trinidad and Tobago Newsday were of a better scientific quality than those in the Trinidad Guardian. These findings suggest a need to improve the overall scientific quality of reported health research in these newspapers by ensuring that reports answer the fundamental questions of what, why, who, where, when and how. This might be achieved by adopting a structured reporting format similar to that used by many peer-reviewed journals. PMID:16459512

Proponemos una tipología de las reivindicaciones epistémicas en la que distinguimos, en función del tipo de contenido que éstas promueven, las reivindicaciones teóricas, metodológicas y performativas. Los resultados muestran que el tipo de reivindicación epistémica está asociado a la estrategia de citación. El método que proponemos contribuye al estudio de la construcción colectiva del conocimiento, pues permite diferenciar las estrategias académicas que los autores movilizan y el tipo de conocimiento reivindicado. Abstract in english Epistemic claims are actions in which the actors apply their knowledge socially. 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.

Human serum albumin (HSA) is a versatile and important protein for the pharmaceutical industry (Fanali et al., Mol. Aspects Med. 33(3) (2012) 209-290). Due to the potential transmission of pathogens from plasma sourced albumin, numerous expression systems have been developed to produce recombinant HSA (rHSA) (Chen et al., Biochim. Biophys. Acta (BBA)-Gen. Subj. 1830(12) (2013) 5515-5525; Kobayashi, Biologicals 34(1) (2006) 55-59). Based on our previous study showing increased glycation of rHSA expressed in Asian rice (Frahm et al., J. Phys. Chem. B 116(15) (2012) 4661-4670), both supplier-to-supplier and lot-to-lot variability of rHSAs from a number of expression systems were evaluated using reversed phase liquid chromatography linked with MS and MS/MS analyses. The data are associated with the research article 'Determination of Supplier-to-Supplier and Lot-to-Lot Variability in Glycation of Recombinant Human Serum Albumin Expressed in Oryza sativa' where further analysis of rHSA samples with additional biophysical methods can be found (Frahm et al., PLoS ONE 10(9) (2014) e109893). We determined that all rHSA samples expressed in rice showed elevated levels of arginine and lysine hexose glycation compared to rHSA expressed in yeast, suggesting that the extensive glycation of the recombinant proteins is a by-product of either the expression system or purification process and not a random occurrence.

The authors of this article have been writing together about practitioner research and inquiry for more than 25 years. In this article, they trace the roots of this interest to their work with K-12 teachers and school leaders over many years and their dissatisfaction with the idea that external researchers produce all the knowledge necessary to change teaching, learning and schooling. The article also highlights the notion of inquiry as stance, which contrasts with the idea that inquiry is ...
Full Text Available The key of teaching is to design some "Teaching Main Line ", and ultimately to impart the knowledge and its structure of teachers and teaching materials to students themselves knowledge and its structure. This research indicates that the knowledge /system inner logic are differ from students comprehension logic, the teaching process in general is a kind of linearization process of teaching knowledge. Discussed the linearization of teaching process, as for transformation and restoration of the knowledge/system structure. Therefore given a Systems-Science Based Knowledge Model (SSBKM for structure and organization methods of a knowledge; especially focuses on the teaching mainline method based on SSBKM. Think that only organizing teaching based on a certain Teaching Mainline, making teaching process linearization and finally restoring the original knowledge and its structure, can we really take for acquire and mastery of the knowledge. The article also mentioned the method that promote Teaching Mainline: the multiple cycle teaching methods of ponging over, browsing, reading, learning, exercising, practicing and applying. The article also takes this paper as "a knowledge" example, the Y, given the teaching expression method of Y based on systems science.

Reigning regulatory frameworks for biomedical research impose on researchers and research ethics committees an obligation to protect research participants from risks that are unnecessary, disproportionate to potential research benefits, and non-minimized. Where the research has no potential to produce results of direct benefit to the subjects and the subjects are unable to give consent, these requirements are strengthened by an additional condition, that risks should not exceed a certain minimal threshold. In this article, I address the question of whether there should be limits of permissible risks in non-therapeutic research involving competent and healthy subjects. Some commentators argue that competent and informed individuals should have a right to participate even in extremely risky research and that research ethics committees should never reject studies because they are too dangerous. To use David Shaw's expression, competent volunteers should have 'a right to participate in high-risk research'. I argue that this idea is ill-founded, as it does not take into account the social mission and complex collaborative nature of research practice as well as the inequity of power between researchers and subjects. Imposition of limits on permissible risks for healthy volunteers is justified by the need to protect research enterprise and the need to protect the weaker party, namely the subjects. Also, I suggest that the best way to set boundaries on research risks is to leave the judgment of risk acceptability to research ethics committees. PMID:25644532

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.

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.

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 current issue of IJHDR begins by a now classical dilemma relative to the high dilutions: if they lack biological effects, how might they cause adverse effects? The plausibility of the implausible is once again the subject of a letter addressed to this Editor. The present issue further features three articles from Indian authors, which somehow makes the occasion special, and worthy of reflection: what is going on in Indian homeopathy? As it is known, India has always played a significant role in the homeopathic stage by contributing with original clinical protocols and approaches. More recently, India has shown the world unexpected scientific features of the high dilutions. The natural and cultural diversity of India seems to influence the research it conducts, which ranges from physicochemical and biological studies performed in research centers and universities to clinical trials conducted in hospitals, in addition to a major concern with education. India has thus become one of the main centers concerned with the scientific side of homeopathy, which is further attested by the organization of, and participation in major scientific meetings like the LMHI congress of 2011, GIRI meetings, and the latest HRI conference, and publication in IJHDR and other scientific journals. As an example of the multiple interests of homeopathic research in India, one article in this issue of IJHDR addresses a fundamental research problem, another the patients satisfaction, and the third the perspective of undergraduates on the teaching of homeopathy. This same movement observed in India has been observed in other countries like Brazil and Russia among others, following many European countries, making possible and feasible the existence of an international scientific network connecting the various groups devoted to HD research across the world. IJHDR is proud to participate on this endeavor!

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.

While trying to understand and characterize users behavior online, the temporal dimension has received little attention by the research community. This exploratory study uses two collections of web search queries to investigate the use of temporal information needs. Using state-of-the-art information extraction techniques we identify temporal expressions in these queries. We find that temporal expressions are rarely used (1.5% of queries) and, when used, they are related to current and...

"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.

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 caregiverinfant 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.
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.

First and second chambers, each having a rotor, are interconnected by a passage. The first chamber has a contoured periphery to receive articles and the passage is shaped and dimensioned to permit travel therealong only of those articles which are orientated in the first chamber with their longitudinal axes either in the direction of travel or normal to the direction of travel. Articles in other orientations are carried round the first chamber by the rotor for representation at the passage. The rotor in the second chamber permits the passage of those articles which have their longitudinal axes in the direction of travel and topples by means of blades, the articles having their axes normal to the direction of travel into positions in which the axes are in the direction of travel.

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.

XML-based production of journal articles, combined with real-time transformations, now make it possible to develop new enhancements to the reading experience and to the content of the article itself. Papers from AAS journals are now available in Article Evolution HTML format, providing both familiar and new functionality that improves the reading experience. This poster will outline the roadmap for the development of Article Evolution functionality and ask for input to help shape future enhancements that meet the needs of the astronomy community. Two of the ongoing developments described are semantic enrichment of articles and adoption of ORCID (Open Researcher and Contributor ID). Both of these have exciting possibilities at an article level within Article Evolution but will also impact widely on third party services, such as linking and discovery of research papers.

Objective: To explore the mechanisms of cytokines on acute radiation disease in irradiation beagles. Methods: The sera of beagles irradiated with 4.5 Gy ?-rays with cytokines treatment was collected at different time points post irradiation. The two-dimensional gel electrophoresis (2-DE) was differentially expressed proteins with significance, and the amino acid sequences should be determined. Results: High resolution 2-DE gel map was obtained. There were six differentially expressed proteins in sera of irradiated beagles at different time points. Four protein spots were successfully identified by MS. A significant spot was identified as serum amyloid A (SAA) by HD-MS, with relative molecular mass of 13 077 and isoelectric point of 6.26. Expression of SAA was not found 1 d pre-irradiation and 36 d post-irradiation, but increased slightly 1 d (0.2166) and significantly 14 d post-irradiation (0.4577). Conclusions: The expression of serum amyloid A was consistent with the process of acute radiation injury, which might indicate the turnover of the disease. (authors)

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 masters 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.

Computer animation researchers have been extensively investigating 3D facial-expression synthesis for decades. However, flexible, robust production of realistic 3D facial expressions is still technically challenging. A proposed modeling framework applies sparse coding to synthesize 3D expressive faces, using specified coefficients or expression examples. It also robustly recovers facial expressions from noisy and incomplete data. This approach can synthesize higher-quality expressions in less time than the state-of-the-art techniques. PMID:24804949

This interactive pan balance allows students to enter numeric or algebraic expressions and investigate the important concept of equivalence as well as practice arithmetic and algebraic skills. Users place an expression in each of the red and blue pans. These expressions may or may not include the variable x. If the expression is algebraic, a value for x is entered or adjusted by moving the slider. As the value of x changes, the results will be weighed and graphed. Instructions and exploration directions and questions are included.
Full Text Available Abstract Background Pseudogenes, the nonfunctional homologues of functional genes are now coming to light as important resources regarding the study of human protein evolution. Processed pseudogenes arising by reverse transcription and reinsertion can provide molecular record on the dynamics and evolution of genomes. Researches on the progenitors of human processed pseudogenes delved out their highly expressed and evolutionarily conserved characters. They are reported to be short and GC-poor indicating their high efficiency for retrotransposition. In this article we focused on their high expressivity and explored the factors contributing for that and their relevance in the milieu of protein sequence evolution. Results We here, analyzed the high expressivity of these genes configuring processed or retropseudogenes by their immense connectivity in protein-protein interaction network, an inclination towards alternative splicing mechanism, a lower rate of mRNA disintegration and a slower evolutionary rate. While the unusual trend of the upraised disorder in contrast with the high expressivity of the proteins encoded by processed pseudogene ancestors is accredited by a predominance of hub-protein encoding genes, a high propensity of repeat sequence containing genes, elevated protein stability and the functional constraint to perform the transcription regulatory jobs. Linear regression analysis demonstrates mRNA decay rate and protein intrinsic disorder as the influential factors controlling the expressivity of these retropseudogene ancestors while the latter one is found to have the most significant regulatory power. Conclusions Our findings imply that, the affluence of disordered regions elevating the network attachment to be involved in important cellular assignments and the stability in transcriptional level are acting as the prevailing forces behind the high expressivity of the human genes configuring processed pseudogenes.

[Correction Notice: An Erratum for this article was reported in Vol 144(4) of Journal of Experimental Psychology: General (see record 2015-33206-002). In the article the labels on the X-axis of Figure 1 "Remove Variance" and "Preserve Variance" should be switched.] Symbolic material objects such as art or certain artifacts (e.g., fine pottery, jewelry) share one common element: The combination of generating an expression, and the materialization of this expression in the object. This explains why people place a much greater value on handmade over machine-made objects, and originals over duplicates. We show that this mechanism occurs when a material object's symbolic property is salient and when the creator (artist or craftsman) is perceived to have agency control over the 1-to-1 materialized expression in the object. Coactivation of these 2 factors causes the object to be perceived as having high value because it is seen as the embodied representation of the creator's unique personal expression. In 6 experiments, subjects rated objects in various object categories, which varied on the type of object property (symbolic, functional, aesthetic), the production procedure (handmade, machine-made, analog, digital) and the origin of the symbolic information (person or software). The studies showed that the proposed mechanism applies to symbolic, but not to functional or aesthetic material objects. Furthermore, they show that this specific form of symbolic object valuation could not be explained by various other related psychological theories (e.g., uniqueness, scarcity, physical touching, creative performance). Our research provides a universal framework that identifies a core mechanism for explaining judgments of value for one of our most uniquely human symbolic object categories.

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.

A non-scientific poll of fellow practicing professionals suggests that there is a range of opinions regarding the effectiveness of different ways of becoming acquainted with and using the results of academic research in their practice. Journal articles remain the dominant path for transferring research results to the profession, even though accessing them is becoming more difficult with time. Driven primarily by cost considerations personal and corporate subscriptions seem to be on the decline. Libraries are one of the first victims of cost cutting measures in the industry. Even though the availability of journal articles in electronic form facilitates their availability, their prices are prohibitive. This is especially true during when a professional is searching for a solution to a problem and may have to review several papers on the subject. One colleague suggested that the professional organizations and other publishers of research articles could learn from the experience of the music industry, by lowering the cost of downloading individual papers to something like a dollar per article, recovering thus their production costs through the increase in the volume of purchased articles. The posting on the internet of special reports and dissertations by research institutions is viewed as very useful by those working in practice. The distribution through the internet of reports by federal organizations conducting or sponsoring research, such as the U.S. Geological Survey and the U.S. Environmental Protection Agency is greatly appreciated by the practicing professionals. The use of leading researchers as consultants provides a direct path for bringing research results to the practice, but it is limited to a small number of cases where bringing in a consultant can be justified. Short courses are viewed as an effective way of familiarizing professionals with the latest research findings on specific subjects. The notes distributed in such courses are considered especially useful. Conferences and special symposia offer the opportunity to practicing professionals to find out what is the latest in different subject areas, but many view such meetings as having either a practical or a research character, and expressed the desire for more meetings that would bring together the practitioners and the researchers. Commercialization is another path for bringing research results to the practice, but is limited to areas where the size of the market for the commercial application of research findings makes it economically viable. The extent of the adoption of research findings in the practice varies across subjects. The results of research in subjects driven by pressing practical needs, such as remediation of contaminated groundwater or hydraulic testing have been passed quickly to the practice. Using the results of research in subjects such as fracture flow and stochastic hydrogeology seems more elusive.

Extreme expressions are really type of emotional expressions that are basically stimulated through the strong emotion. An example of those extreme expression is satisfied through tears. So to be able to provide these types of features; additional elements like fluid mechanism (particle system) plus some of physics techniques like (SPH) are introduced. The fusion of facile animation with SPH exhibits promising results. Accordingly, proposed fluid technique using facial animation is the real tenor for this research to get the complex expression, like laugh, smile, cry (tears emergence) or the sadness until cry strongly, as an extreme expression classification that's happens on the human face in some cases.

Given the implicit nature of visual communication, it will not always be possible for the audio describer to determine emotions unambiguousl...

The beta Weibull distribution was first introduced by Famoye et al. (2005) and studied by these authors and Lee et al. (2007). However, they do not give explicit expressions for the moments. In this article, we derive explicit closed form expressions for the moments of this distribution, which generalize results available in the literature for some sub-models. We also obtain expansions for the cumulative distribution function and Rényi entropy. Further, we discuss maximum likelihood estimatio...
This article shows that there exist two particular linear orders such that first-order logic with these two linear orders has the same expressive power as first-order logic with the Bit-predicate FO(Bit). As a corollary we obtain that there also exists a built-in permutation such that first-order logic with a linear order and this permutation is as expressive as FO(Bit).

This paper introduces a new class of temporal expression named temporal expressions and methods for recognising and interpreting its members. The commonest temporal expressions typically contain date and time words, like April or hours. Research into recognising and interpreting these typical expressions is mature in many languages. However, there is a class of expressions that are less typical, very varied, and difficult to automatically interpret. These indicate dates and times, but are harder to detect because they often do not contain time words and are not used frequently enough to appear in conventional temporally-annotated corpora for example Michaelmas or Vasant Panchami. Using Wikipedia and linked data, we automatically construct a resource of English named temporal expressions, and use it to extract training examples from a large corpus. These examples are then used to train and evaluate a named temporal ex- pression recogniser. We also introduce and evaluate rules for automatically interpreting these expressions, and we observe that use of the rules improves temporal annotation performance over existing corpora

Orthopedic sports medicine continues to evolve, owing much of its clinical management and practice to rigorous academic research. In this review, we identify and describe the top 100 cited articles in clinical sports medicine and recognize the authors and institutions driving the research. We collected articles (excluding basic science, animal, and cadaveric studies) from the 25 highest-impact sports medicine journals and analyzed them by number of citations, journal, publication date, institution, country, topic, and author. Mean number of citations was 408 (range, 229-1629). The articles were published in 7 journals, most in the 1980s to 2000s, and represented 15 countries. Thirty topics were addressed, with a heavy emphasis on anterior cruciate ligament injury and reconstruction, knee rating systems, rotator cuff reconstruction, and chondrocyte transplantation. The 3 most cited articles, by Insall and colleagues, Constant and Murley, and Tegner and Lysholm, addressed a knee, a shoulder, and another knee rating system, respectively. Several authors contributed multiple articles. The Hospital for Special Surgery and the University of Bern contributed the most articles (5 each). This study provides a comprehensive list of the past century's major academic contributions to sports medicine. Residents and fellows may use this list to guide their scholarly investigations.

Many initiatives encourage investigators to share their raw datasets in hopes of increasing research efficiency and quality. Despite these investments of time and money, we do not have a firm grasp of who openly shares raw research data, who doesn't, and which initiatives are correlated with high rates of data sharing. In this analysis I use bibliometric methods to identify patterns in the frequency with which investigators openly archive their raw gene expression microarray datasets after study publication. Automated methods identified 11,603 articles published between 2000 and 2009 that describe the creation of gene expression microarray data. Associated datasets in best-practice repositories were found for 25% of these articles, increasing from less than 5% in 2001 to 30%-35% in 2007-2009. Accounting for sensitivity of the automated methods, approximately 45% of recent gene expression studies made their data publicly available. First-order factor analysis on 124 diverse bibliometric attributes of the data creation articles revealed 15 factors describing authorship, funding, institution, publication, and domain environments. In multivariate regression, authors were most likely to share data if they had prior experience sharing or reusing data, if their study was published in an open access journal or a journal with a relatively strong data sharing policy, or if the study was funded by a large number of NIH grants. Authors of studies on cancer and human subjects were least likely to make their datasets available. These results suggest research data sharing levels are still low and increasing only slowly, and data is least available in areas where it could make the biggest impact. Let's learn from those with high rates of sharing to embrace the full potential of our research output. PMID:21765886
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.

This paper presents a computational model of how conversational participants collaborate in order to make a referring action successful. The model is based on the view of language as goal-directed behavior. We propose that the content of a referring expression can be accounted for by the planning paradigm. Not only does this approach allow the processes of building referring expressions and identifying their referents to be captured by plan construction and plan inference, i...

Myoglobin is a well-characterized, cytoplasmic hemoprotein that is expressed primarily in cardiomyocytes and oxidative skeletal muscle fibers. However, recent studies also suggest low-level myoglobin expression in various non-muscle tissues. Prior studies incorporating molecular, pharmacological, physiological and transgenic technologies have demonstrated that myoglobin is an essential oxygen-storage hemoprotein capable of facilitating oxygen transport and modulating nitric oxide homeostasis ...

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.

Full Text Available Breast cancer is the most common and the leading cause of mortality in women worldwide. There is a dire necessity of the identification of novel molecules useful in diagnosis and prognosis. In this work we determined the differentially expression profiles of four breast cancer cell lines compared to a control cell line. We identified 1020 polypeptides labelled with iTRAQ with more than 95% in confidence. We analysed the common proteins in all breast cancer cell lines through IPA software (IPA core and Biomarkers. In addition, we selected the specific overexpressed and subexpressed proteins of the different molecular classes of breast cancer cell lines, and classified them according to protein class and biological process. Data in this article is related to the research article Determination of the protein expression profiles of breast cancer cell lines by Quantitative Proteomics using iTRAQ Labelling and Tandem Mass Spectrometry (Calderón-González et al.  in press.

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.

Microarrays are made it possible to simultaneously monitor the expression profiles of thousands of genes under various experimental conditions. It is used to identify the co-expressed genes in specific cells or tissues that are actively used to make proteins. This method is used to analysis the gene expression, an important task in bioinformatics research. Cluster analysis of gene expression data has proved to be a useful tool for identifying co-expressed genes, biologically relevant groupings of genes and samples. In this paper we applied K-Means with Automatic Generations of Merge Factor for ISODATA- AGMFI. Though AGMFI has been applied for clustering of Gene Expression Data, this proposed Enhanced Automatic Generations of Merge Factor for ISODATA- EAGMFI Algorithms overcome the drawbacks of AGMFI in terms of specifying the optimal number of clusters and initialization of good cluster centroids. Experimental results on Gene Expression Data show that the proposed EAGMFI algorithms could identify compact clus...

Research on the expression of adhesion molecules, E-cadherin (ECAD), CD24, CD44 and osteopontin (OPN) in colorectal cancer (CRC) has been limited, even though CRC is one of the leading causes of cancer-related deaths. This study was conducted to evaluate the expression of adhesion molecules in CRC and to determine their relationships with clinicopathologic variables, and the prognostic significance. The expression of ECAD, CD24, CD44 and OPN was examined in 174 stage II and III CRC specimens by immunohistochemistry of TMA. Negative ECAD expression was significantly correlated with advanced nodal stage and poor tumor differentiation. Multivariate analysis showed that both negative expression of ECAD and positive expression of CD24 were independent prognostic factors for disease-free survival (DFS) in CRC patients (PECAD negativity showed statistically significant results in multivariate analysis (PECAD and CD24 expression can be considered independent prognostic factors. The role of CD44 and OPN may need further evaluation. PMID:26097606

Full Text Available One of the final goals of high school education is to prepare students to be able to master independently written form of expression. Therefore, during all four years of schooling, they are introduced to the contents required for independent research work.In this process, school librarian has an important role. With the curriculum of library and information skills (LIS, the school library participates in different phases of the research process from first year of high school on, helping students and mentors find themes for their research, retrieve, select, use and evaluate information sources, as well as with citing, bibliography and presentation. The librarian as the expert for retrieving and organization is a co-mentor of research work, together with teachers who are professionals in their respective professional fields. Because of special information needs, the librarian cooperates with other libraries, takes care of interlibrary loan and organizes a local collection of graduate and other research works making them freely accesible.The article presents different forms of research work of students on the case of Maribor High School II, some of them regular and obligatory in the education process and some of them chosen freely, and the role of librarian as an intermediate element in this process.The article also presents the opinions of teachers on research work in school and the role of schoollibrary and schoollibrarians in this process.

Introduction Recent studies have shown that astrocytes play major roles in normal and disease condition of the central nervous system including multiple sclerosis (MS). Molecular target therapy studies in MS have revealed that connexin-43 (Cx43) and Aquaporin-4 (AQP4) contents of astrocytes undergo expression alteration. Fluoxetine had some effects in MS patients unrelated to its known antidepressant effects. Some of fluoxetine effects were attributed to its capability of cAMP signaling pathway stimulation. This study aimed to investigate possible acute effects of fluoxetine on Cx43 and AQP4 expression in astrocyte. Methods Astrocytoma cells were treated for 24 hours with fluoxetine (10 and 20 µg/ml) with or without adenyl cyclase (AC) and protein kinase A (PKA) inhibition. Cx43 expression at both mRNA and protein levels and AQP4 expression at mRNA level were evaluated. Results Acquired results showed that fluoxetine with and without AC and PKA inhibition resulted in Cx43 up-regulation both in mRNA and protein levels, whereas AQP4 expression have not changed. Discussion In conclusion, data showed that fluoxetine alone and in the absence of serotonin acutely up-regulated Cx43 expression in astrocytes that can be assumed in molecular target therapy of MS patients. It seems that cAMP involvement in fluoxetine effects need more researches. PMID:25436087
Full Text Available Problem statement: The studies on Thai expressive speech or emotional speech have been conducted for years. Most of them are expected to analysis the characteristics of Thai expressive speech. However, the conclusive reviews on these studies have not been conducted for further study on the speech technology or application of Thai expressive speech. Approach: The review of research on Thai expressive speech in various aspects has been performed. They include an analysis of fundamental frequency contours using Fujisakis model, an analysis of fundamental frequency contours using structural model and speech compression with noisy environments. It has been noted that four speaking emotions include enjoyable, sad, angry and reading styles. Results: A comparison of two successful F0 models has been reviewed. One approach is based on the Fujisakis model which has been applied for many tonal and toneless languages. Another one is based on the structural model which has been conducted primarily for Mandarin Chinese. Moreover, a study of speech compression for noise-corrupted Thai expressive speech by using two coding methods of CS-ACELP and MP-CELP has been summarized. Conclusion: From the study, it can be seen that two mathematical models have been successfully applied to model the fundamental frequency contour of Thai expressive speech. As for speech compression, it can be seen that coding methods, types of noise, levels of noise, speech gender influence on the coding speech quality.

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

Detection of differential gene expression using microarray technology has received considerable interest in cancer research studies. Recently, many researchers discovered that oncogenes may be activated in some but not all samples in a given disease group. The existing statistical tools for detecting differentially expressed genes in a subset of the disease group mainly include cancer outlier profile analysis (COPA), outlier sum (OS), outlier robust t-statistic (ORT) and maximum ordered subse...
Full Text Available A number of European languages have undergone a change from object-verb to verb-object order. We focus on the change in English and Icelandic, showing that while the structural change was the same, it took place at different times and different ways in the two languages, triggered by different E-language changes. As seen from the English viewpoint, low-level facts of inflection morphology may express the relevant cue for parameters, and so the loss of inflection may lead to a grammar change. This analysis does not carry over to Icelandic, as the loss of OV there took place despite rich case morphology. We aim to show how this can be explained within a cue-style approach, arguing for a universal set of cues. However, the relevant cue may be expressed differently among languages: While it may have been expressed through morphology in English, it as expressed through information structure in Icelandic. In both cases, external effects led to fewer expressions of the relevant (universal cue and a grammar change took place.
