  1. A Federated Search Approach to Facilitate Systematic Literature Review in Software Engineering

    Directory of Open Access Journals (Sweden)

    2012-04-01

    Full Text Available To impact industry, researchers developing technologies in academia need to provide tangible evidence of the advantages of using them. Nowadays, Systematic Literature Review (SLR has become a prominent methodology in evidence-based researches. Although adopting SLR in software engineering does not go far in practice, it has been resulted in valuable researches and is going to be more common. However, digital libraries and scientific databases as the best research resources do not provide enough mechanism for SLRs especially in software engineering. On the other hand, any loss of data may change the SLR results and leads to research bias. Accordingly, the search process and evidence collection in SLR is a critical point. This paper provides some tips to enhance the SLR process. The main contribution of this work ispresenting a federated search tool which provides an automatic integrated search mechanism in wellknown Software Engineering databases. Results of case study show that this approach not only reduces required time to do SLR and facilitate its search process, but also improves its reliability and results in the increasing trend to use SLRs.

    2015-01-01

    The search of images on the internet has become a natural process for the internet surfer. Most of the search engines use complex algorithms to look up for images but their metadata is mostly ignored, in part because many image hosting sites remove metadata when the image is uploaded. The JPSearch standard has been developed to handle interoperability in metadata based searches, but it seems that the market is not interested on supporting it. The starting point of this proje...

    Recently there is an increase in smaller, domain-specific search engines that scour the deep web finding information that general-purpose engines are unable to discover. These search engines play a crucial role in the new generation of search paradigms where federated search engines (FSEs) integrate search results from heterogeneous sources. In this paper we pose, for the first time, the problem to design a revenue mechanism that ensures profits both to individual search engines and FSEs as a...

    Full Text Available The Internet provides a quick access to a plethora of the medical literature, in the form of journals, databases, dictionaries, textbooks, indexes, and e-journals, thereby allowing access to more varied, individualized, and systematic educational opportunities. Web search engine is a tool designed to search for information on the World Wide Web, which may be in the form of web pages, images, information, and other types of files. Search engines for internet-based search of medical literature include Google, Google scholar, Yahoo search engine, etc., and databases include MEDLINE, PubMed, MEDLARS, etc. Commercial web resources (Medscape, MedConnect, MedicineNet add to the list of resource databases providing some of their content for open access. Several web-libraries (Medical matrix, Emory libraries have been developed as meta-sites, providing useful links to health resources globally. Availability of specific dermatology-related websites (DermIs, DermNet, and Genamics Jornalseek is useful addition to the ever growing list of web-based resources. A researcher must keep in mind the strengths and limitations of a particular search engine/database while searching for a particular type of data. Knowledge about types of literature and levels of detail available, user interface, ease of access, reputable content, and period of time covered allow their optimal use and maximal utility in the field of medicine.

  10. A More Intelligent Literature Search

    Directory of Open Access Journals (Sweden)

    Michael G King

    2014-07-01

    Full Text Available Although the topic of study relates to an environmental/health issue, it is the methodology described which serves to showcase an embryonic form of a new “more intelligent” protocol of search algorithm. Through the implementation of this algorithm, an extensive automated literature base yielded a single credible solution to a previously unsolved problem. Faced with a distressing but entirely unexplained incidence of birth defects, the proposed model of knowledge scavenging worked through acknowledged gaps in understanding of increased (phosphate fertilizer, enabled the template of known facts regarding the interactions of phosphates with the processes of mammal (and other animal growth, of metabolic function, and of neurological development, and delivered a causal model which would not, at least not easily, derive from current literature search methods. Illustrating the practical value of a step forwards in the design of intelligent literature search, the present study provides a candidate cause to explain a cluster of bovine deformity

    2007-01-01

    To facilitate the search for relevant information across a set of online distributed collections, a federated information retrieval system typically represents each collection, centrally, by a set of vocabularies or sampled documents. Accurate retrieval is therefore related to how precise each representation reflects the underlying content stored in that collection. As collections evolve over time, collection representations should also be updated to reflect any change, however, a current sol...

    This paper reports on the development of a tool by the Arizona Health Sciences Library (AHSL) for searching clinical evidence that can be customized for different user groups. The AHSL provides services to the University of Arizona's (UA's) health sciences programs and to the University Medical Center. Librarians at AHSL collaborated with UA College of Medicine faculty to create an innovative search engine, Evidence-based Medicine (EBM) Search, that provides users with a simple search interface to EBM resources and presents results organized according to an evidence pyramid. EBM Search was developed with a web-based configuration component that allows the tool to be customized for different specialties. Informal and anecdotal feedback from physicians indicates that EBM Search is a useful tool with potential in teaching evidence-based decision making. While formal evaluation is still being planned, a tool such as EBM Search, which can be configured for specific user populations, may help lower barriers to information resources in an academic health sciences center.

    2014-07-01

    In order to identify genes that are involved in oncogenesis and to understand how such genes affect cancers, abnormal gene expressions in cancers are actively studied. For an efficient access to the results of such studies that are reported in biomedical literature, the relevant information is accumulated via text-mining tools and made available through the Web. However, current Web tools are not yet tailored enough to allow queries that specify how a cancer changes along with the change in gene expression level, which is an important piece of information to understand an involved gene's role in cancer progression or regression. OncoSearch is a Web-based engine that searches Medline abstracts for sentences that mention gene expression changes in cancers, with queries that specify (i) whether a gene expression level is up-regulated or down-regulated, (ii) whether a certain type of cancer progresses or regresses along with such gene expression change and (iii) the expected role of the gene in the cancer. OncoSearch is available through http://oncosearch.biopathway.org.

    Literature searches are essential to evidence-based respiratory care. To conduct literature searches, respiratory therapists rely on search engines to retrieve information, but there is a dearth of literature on the comparative efficiencies of search engines for researching clinical questions in respiratory care. To compare PubMed and Google Scholar search results for clinical topics in respiratory care to that of a benchmark. We performed literature searches with PubMed and Google Scholar, on 3 clinical topics. In PubMed we used the Clinical Queries search filter. In Google Scholar we used the search filters in the Advanced Scholar Search option. We used the reference list of a related Cochrane Collaboration evidence-based systematic review as the benchmark for each of the search results. We calculated recall (sensitivity) and precision (positive predictive value) with 2 x 2 contingency tables. We compared the results with the chi-square test of independence and Fisher's exact test. PubMed and Google Scholar had similar recall for both overall search results (71% vs 69%) and full-text results (43% vs 51%). PubMed had better precision than Google Scholar for both overall search results (13% vs 0.07%, P Advanced Scholar Search in Google Scholar for respiratory care topics. PubMed appears to be more practical to conduct efficient, valid searches for informing evidence-based patient-care protocols, for guiding the care of individual patients, and for educational purposes.

  10. Searching for grey literature for systematic reviews: challenges and benefits.

    Science.gov (United States)

    Mahood, Quenby; Van Eerd, Dwayne; Irvin, Emma

    2014-09-01

    There is ongoing interest in including grey literature in systematic reviews. Including grey literature can broaden the scope to more relevant studies, thereby providing a more complete view of available evidence. Searching for grey literature can be challenging despite greater access through the Internet, search engines and online bibliographic databases. There are a number of publications that list sources for finding grey literature in systematic reviews. However, there is scant information about how searches for grey literature are executed and how it is included in the review process. This level of detail is important to ensure that reviews follow explicit methodology to be systematic, transparent and reproducible. The purpose of this paper is to provide a detailed account of one systematic review team's experience in searching for grey literature and including it throughout the review. We provide a brief overview of grey literature before describing our search and review approach. We also discuss the benefits and challenges of including grey literature in our systematic review, as well as the strengths and limitations to our approach. Detailed information about incorporating grey literature in reviews is important in advancing methodology as review teams adapt and build upon the approaches described.

  11. Full text and figure display improves bioscience literature search.

    Directory of Open Access Journals (Sweden)

    Full Text Available When reading bioscience journal articles, many researchers focus attention on the figures and their captions. This observation led to the development of the BioText literature search engine, a freely available Web-based application that allows biologists to search over the contents of Open Access Journals, and see figures from the articles displayed directly in the search results. This article presents a qualitative assessment of this system in the form of a usability study with 20 biologist participants using and commenting on the system. 19 out of 20 participants expressed a desire to use a bioscience literature search engine that displays articles' figures alongside the full text search results. 15 out of 20 participants said they would use a caption search and figure display interface either frequently or sometimes, while 4 said rarely and 1 said undecided. 10 out of 20 participants said they would use a tool for searching the text of tables and their captions either frequently or sometimes, while 7 said they would use it rarely if at all, 2 said they would never use it, and 1 was undecided. This study found evidence, supporting results of an earlier study, that bioscience literature search systems such as PubMed should show figures from articles alongside search results. It also found evidence that full text and captions should be searched along with the article title, metadata, and abstract. Finally, for a subset of users and information needs, allowing for explicit search within captions for figures and tables is a useful function, but it is not entirely clear how to cleanly integrate this within a more general literature search interface. Such a facility supports Open Access publishing efforts, as it requires access to full text of documents and the lifting of restrictions in order to show figures in the search interface.

    A systematic review into palliative care team effectiveness was undertaken which has, inherent in its methodology, grey literature searching. Over 100 letters were written to a systematically chosen range of service providers, commissioners, and experts in combination with requests for information in six UK national cancer/palliative care organization newsletters. In addition, the System for Information on Grey Literature (SIGLE ) database was searched. As a result, 25 document hard copies were received. The documents were, in all but one case (this one study was also highlighted by the SIGLE search), not relevant as they were predominated by annual reports, service descriptions, and needs assessments. In terms of obtaining unpublished studies for possible inclusion in the review, this comprehensive search was unsuccessful and, therefore, it would appear that grey literature searching is not a useful tool in palliative care systematic reviews.

    This report documents a literature search on carbon monoxide. The search was limited to the medical and toxicological databases at the National Library of Medicine (MEDLARS). The databases searched were Medline, Toxline and TOXNET. Searches were performed using a variety of strategies. Combinations of the following keywords were used: carbon, monoxide, accidental, residential, occult, diagnosis, misdiagnosis, heating, furnace, and indoor. The literature was searched from 1966 to the present. Over 1000 references were identified and summarized using the following abbreviations: The major findings of the search are: (1) Acute and subacute carbon monoxide exposures result in a large number of symptoms affecting the brain, kidneys, respiratory system, retina, and motor functions. (2) Acute and subacute carbon monoxide (CO) poisonings have been misdiagnosed on many occasions. (3) Very few systematic investigations have been made into the frequency and consequences of carbon monoxide poisonings.

    Literature reviews are an essential step in the research process and are included in all empirical and review articles. Electronic databases are commonly used to gather this literature. However, several factors can affect the extent to which relevant articles are retrieved, influencing future research and conclusions drawn. The current project examined articles obtained by comparable search strategies in two electronic archives using an exemplar search to illustrate factors that authors should consider when designing their own search strategies. Specifically, literature searches were conducted in PsycINFO and PubMed targeting review articles on two exemplar disorders (bipolar disorder and attention deficit/hyperactivity disorder) and issues of classification and/or differential diagnosis. Articles were coded for relevance and characteristics of article content. The two search engines yielded significantly different proportions of relevant articles overall and by disorder. Keywords differed across search engines for the relevant articles identified. Based on these results, it is recommended that when gathering literature for review papers, multiple search engines should be used, and search syntax and strategies be tailored to the unique capabilities of particular engines. For meta-analyses and systematic reviews, authors may consider reporting the extent to which different archives or sources yielded relevant articles for their particular review.

    2005-10-24

    It is increasingly difficult for clinicians to keep up-to-date with the rapidly growing biomedical literature. Online evidence retrieval methods are now seen as a core tool to support evidence-based health practice. However, standard search engine technology is not designed to manage the many different types of evidence sources that are available or to handle the very different information needs of various clinical groups, who often work in widely different settings. The objectives of this paper are (1) to describe the design considerations and system architecture of a wrapper-mediator approach to federate search system design, including the use of knowledge-based, meta-search filters, and (2) to analyze the implications of system design choices on performance measurements. A trial was performed to evaluate the technical performance of a federated evidence retrieval system, which provided access to eight distinct online resources, including e-journals, PubMed, and electronic guidelines. The Quick Clinical system architecture utilized a universal query language to reformulate queries internally and utilized meta-search filters to optimize search strategies across resources. We recruited 227 family physicians from across Australia who used the system to retrieve evidence in a routine clinical setting over a 4-week period. The total search time for a query was recorded, along with the duration of individual queries sent to different online resources. Clinicians performed 1662 searches over the trial. The average search duration was 4.9 +/- 3.2 s (N = 1662 searches). Mean search duration to the individual sources was between 0.05 s and 4.55 s. Average system time (ie, system overhead) was 0.12 s. The relatively small system overhead compared to the average time it takes to perform a search for an individual source shows that the system achieves a good trade-off between performance and reliability. Furthermore, despite the additional effort required to incorporate the

    Full Text Available Abstract Background The taxonomic name of an organism is a key link between different databases that store information on that organism. However, in the absence of a single, comprehensive database of organism names, individual databases lack an easy means of checking the correctness of a name. Furthermore, the same organism may have more than one name, and the same name may apply to more than one organism. Results The Taxonomic Search Engine (TSE is a web application written in PHP that queries multiple taxonomic databases (ITIS, Index Fungorum, IPNI, NCBI, and uBIO and summarises the results in a consistent format. It supports "drill-down" queries to retrieve a specific record. The TSE can optionally suggest alternative spellings the user can try. It also acts as a Life Science Identifier (LSID authority for the source taxonomic databases, providing globally unique identifiers (and associated metadata for each name. Conclusion The Taxonomic Search Engine is available at http://darwin.zoology.gla.ac.uk/~rpage/portal/ and provides a simple demonstration of the potential of the federated approach to providing access to taxonomic names.

    2006-10-01

    Systematic reviews of qualitative research studies extend understanding of health care beyond effectiveness to acceptability and user views. The paper surveys reports of qualitative systematic reviews and, by characterizing techniques used to identify articles for inclusion, proposes standards for reporting of literature searches. A search of MEDLINE was performed for qualitative systematic reviews published from 1988 to December 2004, supported by searches of CINAHL, Web of Knowledge (including the Science and Social Sciences Citation Index), and the Cochrane Methodology Register, and Internet searches using the Copernic Agent Professional meta-search agent. Studies were included if they used techniques of qualitative synthesis in reviewing research studies in health care. Narrative reviews were excluded. Authors, year of publication, sampling strategy, databases, keywords, and other approaches used were extracted. Sixty-four studies were identified, and forty-three met inclusion criteria for this review. A summary of searching methods was produced and used to construct the STARLITE mnemonic (sampling strategy, type of study, approaches, range of years, limits, inclusion and exclusions, terms used, electronic sources). Considerable variation exists in search methods for qualitative systematic reviews. While diversity in methods is appropriate during the development of review methodology, major concerns remain about the absence of an accepted standard and the consequent poor quality of reporting.

  2. The Importance of Species Name Synonyms in Literature Searches

    Science.gov (United States)

    2016-01-01

    The synonyms of biological species names are shown to be an important component in comprehensive searches of electronic scientific literature databases but they are not well leveraged within the major literature databases examined. For accepted or valid species names in the Integrated Taxonomic Information System (ITIS) which have synonyms in the system, and which are found in citations within PLoS, PMC, PubMed or Scopus, both the percentage of species for which citations will not be found if synonyms are not used, and the percentage increase in number of citations found by including synonyms are very often substantial. However, there is no correlation between the number of synonyms per species and the magnitude of the effect. Further, the number of citations found does not generally increase proportionally to the number of synonyms available. Users looking for literature on specific species across all of the resources investigated here are often missing large numbers of citations if they are not manually augmenting their searches with synonyms. Of course, missing citations can have serious consequences by effectively hiding critical information. Literature searches should include synonym relationships and a new web service in ITIS, with examples of how to apply it to this issue, was developed as a result of this study, and is here announced, to aide in this.

    Full Text Available Differing terminology and database structure hinders meaningful cross search of excavation datasets. Matching free text grey literature reports with datasets poses yet more challenges. Conventional search techniques are unable to cross search between archaeological datasets and Web-based grey literature. Results are reported from two AHRC funded research projects that investigated the use of semantic techniques to link digital archive databases, vocabularies and associated grey literature. STAR (Semantic Technologies for Archaeological Resources was a collaboration between the University of Glamorgan, Hypermedia Research Unit and English Heritage (EH. The main outcome is a research Demonstrator (available online, which cross searches over excavation datasets from different database schemas, including Raunds Roman, Raunds Prehistoric, Museum of London, Silchester Roman and Stanwick sampling. The system additionally cross searches over an extract of excavation reports from the OASIS index of grey literature, operated by the Archaeology Data Service (ADS. A conceptual framework provided by the CIDOC Conceptual Reference Model (CRM integrates the different database structures and the metadata automatically generated from the OASIS reports by natural language processing techniques. The methods employed for extracting semantic RDF representations from the datasets and the information extraction from grey literature are described. The STELLAR project provides freely available tools to reduce the costs of mapping and extracting data to semantic search systems such as the Demonstrator and to linked data representation generally. Detailed use scenarios (and a screen capture video provide a basis for a discussion of key issues, including cost-benefits, ontology modelling, mapping, terminology control, semantic implementation and information extraction issues. The scenarios show that semantic interoperability can be achieved by mapping and extracting

    Full Text Available Abstract Background It is difficult to systematically search for literature relevant to palliative care in general medical journals. A previously developed search filter for use on OVID Medline validated using a gold standard set of references identified through hand searching, achieved an unacceptably low sensitivity (45.4%. Retrieving relevant literature is integral to support evidence based practice, and understanding the nature of the incorrectly excluded citations (false negatives using the filter may lead to improvement in the filter's performance. Methods The objectives were to describe the nature of subjects reflected in the false negative citations and to empirically improve the sensitivity of the search filter. A thematic analysis of MeSH terms by three independent reviewers was used to describe the subject coverage of the missed records. Using a frequency analysis of MeSH terms, those headings which could individually contribute at least 2.5% to sensitivity (occurring 19 or more times were added to the search filter. All previously run searches were rerun at the same time as the revised filter, and results compared. Results Thematic analysis of MeSH terms identified thirteen themes reflected in the missing records, none of them intrinsically palliative. The addition of six MeSH terms to the existing search filter (physician-patient relations, prognosis, quality of life, survival rate, treatment outcome and attitude to health led to an increase in sensitivity from 46.3% to 64.7%, offset by a decrease in precision from 72.6% to 21.9%. Conclusion The filter's sensitivity was successfully increased using frequency analysis of MeSH terms, offset by a decrease in precision. A thematic analysis of MeSH terms for the false negative citations confirmed the absence of any intrinsically palliative theme or term, suggesting that future improvements to search filters for palliative care literature will first depend on better identifying how

    2013-01-01

    Background Surveying valuable and most recent information from internet, has become vital for researchers and scholars, because every day, thousands and perhaps millions of scientific works are brought out as digital resources which represented by internet and researchers can’t ignore this great resource to find related documents for their literature search, which may not be found in any library. With regard to variety of documents presented on the internet, search engines are one of the most effective search tools for finding information. Objectives The aim of this study is to evaluate the three criteria, recall, preciseness and importance of the four search engines which are PubMed, Science Direct, Google Scholar and federated search of Iranian National Medical Digital Library in addiction (prevention and treatment) to select the most effective search engine for offering the best literature research. Materials and Methods This research was a cross-sectional study by which four popular search engines in medical sciences were evaluated. To select keywords, medical subject heading (Mesh) was used. We entered given keywords in the search engines and after searching, 10 first entries were evaluated. Direct observation was used as a mean for data collection and they were analyzed by descriptive statistics (number, percent number and mean) and inferential statistics, One way analysis of variance (ANOVA) and post hoc Tukey in Spss. 15 statistical software. P Value Science Direct and Google Scholar were the best in recall, preciseness and importance respectively. Conclusions As literature research is one of the most important stages of research, it's better for researchers, especially Substance-Related Disorders scholars to use different search engines with the best recall, preciseness and importance in that subject field to reach desirable results while searching and they don’t depend on just one search engine.

  3. Federated Space-Time Query for Earth Science Data Using OpenSearch Conventions

    2009-12-01

    The past decade has seen a burgeoning of remote sensing and Earth science data providers, as evidenced in the growth of the Earth Science Information Partner (ESIP) federation. At the same time, the need to combine diverse data sets to enable understanding of the Earth as a system has also grown. While the expansion of data providers is in general a boon to such studies, the diversity presents a challenge to finding useful data for a given study. Locating all the data files with aerosol information for a particular volcanic eruption, for example, may involve learning and using several different search tools to execute the requisite space-time queries. To address this issue, the ESIP federation is developing a federated space-time query framework, based on the OpenSearch convention (www.opensearch.org), with Geo and Time extensions. In this framework, data providers publish OpenSearch Description Documents that describe in a machine-readable form how to execute queries against the provider. The novelty of OpenSearch is that the space-time query interface becomes both machine callable and easy enough to integrate into the web browser's search box. This flexibility, together with a simple REST (HTTP-get) interface, should allow a variety of data providers to participate in the federated search framework, from large institutional data centers to individual scientists. The simple interface enables trivial querying of multiple data sources and participation in recursive-like federated searches--all using the same common OpenSearch interface. This simplicity also makes the construction of clients easy, as does existing OpenSearch client libraries in a variety of languages. Moreover, a number of clients and aggregation services already exist and OpenSearch is already supported by a number of web browsers such as Firefox and Internet Explorer.

When the themes of these articles were analiysed, it was determined that 75% (n=21 of them was “multiple myeloma signs, treatment protocols, treatment toxicities, symptom control and nurses’ roles” and 25% (n=7 125 was survival of multiple myeloma and the quality of life”. Conclusion: As a result of this study, it was determined that there was no enough articles about the multiple myeloma. Nurses should assess the patients comprehensively, and they should plan their cares in a holistic approach. [J Contemp Med 2017; 7(1.000: 91-96

    An awareness of how and where to search the education literature, and how to appraise it is essential to be a teacher scholar (an academic who takes a scholarly approach to teaching), to develop high quality education research, and to perform the scholarship of teaching and learning. Most pharmacy faculty scholars do not receive training in searching the education literature. Thus, a framework for searching the education literature is needed. The framework presented here on where and how to search for evidence in the education literature, referred to as the WHEEL for teaching, is meant to serve as a guide for faculty members in conducting comprehensive and exhaustive literature searches for the publication of scholarship of teaching and learning projects, educational research, or approaching one's teaching in a scholarly manner. Key resources to search and methods for searching the education literature are listed and described.

  6. A UDDI Search Engine for SVG Federated Medical Imaging Web Services

    Full Text Available With more and more medical web services appearing on the web, web service’s discovery mechanism becomes essential. UDDI is an online registry standard to facilitate the discovery of business partners and services. However, most medical imaging applications exist within their own protected domain and were never designed to participate and operate with other applications across the web. However, private UDDI registries in federated organizations should be able to share the service descriptions as well as to access them if they are authorized. The new initiatives on Federated Web Services Identity Management can resolve a range of both technical and political barriers to enable wide-scale participation and interoperation of separate domains into a singular, robust user experience. However, there is no widely acceptable standard for federated web services and most of the available venders frameworks concentrate only on the security issue of the federation leaving the issue of searching and discovering web services largely primitive. Federated web services security and web services searching are uniquely intertwined, mutually reliant on each other and are poised to finally solve a long-running problem in both IT and systems security. Traditional keyword search is insufficient for web services search as the very small text fragments in web services are unsuitable for keyword search and the underlying structure and semantics of the web service are not exploited. Engineering solutions that address the security and accessibility concerns of web services, however, is a challenging task. This article introduces an extension to the traditional UDDI that enables sophisticated types of searching based on a lightweight web services federated security infrastructure.

    Full Text Available Google Scholar (GS, a commonly used web-based academic search engine, catalogues between 2 and 100 million records of both academic and grey literature (articles not formally published by commercial academic publishers. Google Scholar collates results from across the internet and is free to use. As a result it has received considerable attention as a method for searching for literature, particularly in searches for grey literature, as required by systematic reviews. The reliance on GS as a standalone resource has been greatly debated, however, and its efficacy in grey literature searching has not yet been investigated. Using systematic review case studies from environmental science, we investigated the utility of GS in systematic reviews and in searches for grey literature. Our findings show that GS results contain moderate amounts of grey literature, with the majority found on average at page 80. We also found that, when searched for specifically, the majority of literature identified using Web of Science was also found using GS. However, our findings showed moderate/poor overlap in results when similar search strings were used in Web of Science and GS (10-67%, and that GS missed some important literature in five of six case studies. Furthermore, a general GS search failed to find any grey literature from a case study that involved manual searching of organisations' websites. If used in systematic reviews for grey literature, we recommend that searches of article titles focus on the first 200 to 300 results. We conclude that whilst Google Scholar can find much grey literature and specific, known studies, it should not be used alone for systematic review searches. Rather, it forms a powerful addition to other traditional search methods. In addition, we advocate the use of tools to transparently document and catalogue GS search results to maintain high levels of transparency and the ability to be updated, critical to systematic reviews.

    Invasive species are a universal global problem, but the information to identify them, manage them, and prevent invasions is stored around the globe in a variety of formats. The Global Invasive Species Information Network is a consortium of organizations working toward providing seamless access to these disparate databases via the Internet. A distributed network of databases can be created using the Internet and a standard web service protocol. There are two options to provide this integration. First, federated searches are being proposed to allow users to search "deep" web documents such as databases for invasive species. A second method is to create a cache of data from the databases for searching. We compare these two methods, and show that federated searches will not provide the performance and flexibility required from users and a central cache of the datum are required to improve performance.

    Gutknecht, Mandy; Krensel, Magdalene; Augustin, Matthias

    2016-11-01

    In the course of the chronic skin disease psoriasis, where a variety of treatment interventions is available, a strong growth of health economic studies comparing treatment costs and benefits can be noticed. The objective was to identify health economic evaluations of psoriasis treatments that have been published to date. Of particular interest were the mostly used analysis and outcome parameters, the compared treatments, and the question, if available health economic studies may be used to perform a meta-analysis of qualitative findings. A systematic literature search using PubMed Medline, Ovid Medline, and Cochrane Library was performed for articles, published and available until mid of January 2016. Among the key words were the terms "psoriasis" and "cost-effectiveness". The search resulted in 318 articles without duplicates. Thereof 60 health economic analyses in psoriasis management were identified. Most of these are cost-effectiveness evaluations (45). The clinical parameter PASI (Psoriasis Area Severity Index) is the most often used cost-effectiveness outcome (33) followed by the Dermatology Life Quality Index (DLQI) (6). In case of cost-utility analyses, QALYs (quality-adjusted life-years) were mostly generated with the help of EuroQol five dimensions questionnaire (EQ-5D) (12), which was partly based on PASI and DLQI values. The majority of health economic studies is focusing on the direct medical and non-medical costs without consideration of productivity losses. Almost 70 % of 60 publications were conducted in Europe. Overall, most considered systemic treatments were the biological agents etanercept (36), adalimumab (27), and infliximab (26) followed by ustekinumab (17) and phototherapy (incl. UV-B, PUVA/psoralen combined with UV-A) (14). Comparisons including only topical treatments mostly focused on vitamin D treatment (14), corticosteroids (13), and coal tar products (6) followed by dithranol (5) and tazarotene (4). Given the setting, compared

    Representatives of the Federal Aviation Administration (FAA) and several air carriers under Title 14 of the Code of Federal Regulations (CFR) Part 121 developed a system-engineering model of the functions of air-carrier operations. Their analyses form the foundation or basic architecture upon which other task areas are based: hazard analyses, performance measures, and risk indicator design. To carry out these other tasks, models may need to be developed using the basic architecture of the Air Carrier Operations System Model (ACOSM). Since ACOSM encompasses various areas of air-carrier operations and can be used to address different task areas with differing but interrelated objectives, the modeling needs are broad. A literature search was conducted to identify and analyze the existing models that may be applicable for pursuing the task areas in ACOSM. The intent of the literature search was not necessarily to identify a specific model that can be directly used, but rather to identify relevant ones that have similarities with the processes and activities defined within ACOSM. Such models may provide useful inputs and insights in structuring ACOSM models. ACOSM simulates processes and activities in air-carrier operation, but, in a general framework, it has similarities with other industries where attention also has been paid to hazard analyses, emphasizing risk management, and in designing risk indicators. To assure that efforts in other industries are adequately considered, the literature search includes publications from other industries, e.g., chemical, nuclear, and process industries. This report discusses the literature search, the relevant methods identified and provides a preliminary assessment of their use in developing the models needed for the ACOSM task areas. A detailed assessment of the models has not been made. Defining those applicable for ACOSM will need further analyses of both the models and tools identified.

  19. PISA: Federated Search in P2P Networks with Uncooperative Peers

    Science.gov (United States)

    Ren, Zujie; Shou, Lidan; Chen, Gang; Chen, Chun; Bei, Yijun

    Recently, federated search in P2P networks has received much attention. Most of the previous work assumed a cooperative environment where each peer can actively participate in information publishing and distributed document indexing. However, little work has addressed the problem of incorporating uncooperative peers, which do not publish their own corpus statistics, into a network. This paper presents a P2P-based federated search framework called PISA which incorporates uncooperative peers as well as the normal ones. In order to address the indexing needs for uncooperative peers, we propose a novel heuristic query-based sampling approach which can obtain high-quality resource descriptions from uncooperative peers at relatively low communication cost. We also propose an effective method called RISE to merge the results returned by uncooperative peers. Our experimental results indicate that PISA can provide quality search results, while utilizing the uncooperative peers at a low cost.

    Surveying valuable and most recent information from internet, has become vital for researchers and scholars, because every day, thousands and perhaps millions of scientific works are brought out as digital resources which represented by internet and researchers can't ignore this great resource to find related documents for their literature search, which may not be found in any library. With regard to variety of documents presented on the internet, search engines are one of the most effective search tools for finding information. The aim of this study is to evaluate the three criteria, recall, preciseness and importance of the four search engines which are PubMed, Science Direct, Google Scholar and federated search of Iranian National Medical Digital Library in addiction (prevention and treatment) to select the most effective search engine for offering the best literature research. This research was a cross-sectional study by which four popular search engines in medical sciences were evaluated. To select keywords, medical subject heading (Mesh) was used. We entered given keywords in the search engines and after searching, 10 first entries were evaluated. Direct observation was used as a mean for data collection and they were analyzed by descriptive statistics (number, percent number and mean) and inferential statistics, One way analysis of variance (ANOVA) and post hoc Tukey in Spss. 15 statistical software. P Value < 0.05 was considered statistically significant. Results have shown that the search engines had different operations with regard to the evaluated criteria. Since P Value was 0.004 < 0.05 for preciseness and was 0.002 < 0.05 for importance, it shows significant difference among search engines. PubMed, Science Direct and Google Scholar were the best in recall, preciseness and importance respectively. As literature research is one of the most important stages of research, it's better for researchers, especially Substance-Related Disorders scholars to use

  1. A Shared Infrastructure for Federated Search Across Distributed Scientific Metadata Catalogs

    The vast amount of science metadata can be overwhelming and highly complex. Comprehensive analysis and sharing of metadata is difficult since institutions often publish to their own repositories. There are many disjoint standards used for publishing scientific data, making it difficult to discover and share information from different sources. Services that publish metadata catalogs often have different protocols, formats, and semantics. The research community is limited by the exclusivity of separate metadata catalogs and thus it is desirable to have federated search interfaces capable of unified search queries across multiple sources. Aggregation of metadata catalogs also enables users to critique metadata more rigorously. With these motivations in mind, the National Snow and Ice Data Center (NSIDC) and Advanced Cooperative Arctic Data and Information Service (ACADIS) implemented two search interfaces for the community. Both the NSIDC Search and ACADIS Arctic Data Explorer (ADE) use a common infrastructure which keeps maintenance costs low. The search clients are designed to make OpenSearch requests against Solr, an Open Source search platform. Solr applies indexes to specific fields of the metadata which in this instance optimizes queries containing keywords, spatial bounds and temporal ranges. NSIDC metadata is reused by both search interfaces but the ADE also brokers additional sources. Users can quickly find relevant metadata with minimal effort and ultimately lowers costs for research. This presentation will highlight the reuse of data and code between NSIDC and ACADIS, discuss challenges and milestones for each project, and will identify creation and use of Open Source libraries.

    A key outcome measure of cancer research training programs is the number of cancer-related peer-reviewed publications after training. Because program graduates do not routinely report their publications, staff must periodically conduct electronic literature searches on each graduate. The purpose of this study is to compare findings of an innovative computer-based automated search program versus repeated manual literature searches to identify post-training peer-reviewed publications. In late 2014, manual searches for publications by former R25 students identified 232 cancer-related articles published by 112 of 543 program graduates. In 2016, a research assistant was instructed in performing Scopus literature searches for comparison with individual PubMed searches on our 543 program graduates. Through 2014, Scopus found 304 cancer publications, 220 of that had been retrieved manually plus an additional 84 papers. However, Scopus missed 12 publications found manually. Together, both methods found 316 publications. The automated method found 96.2 % of the 316 publications while individual searches found only 73.4 %. An automated search method such as using the Scopus database is a key tool for conducting comprehensive literature searches, but it must be supplemented with periodic manual searches to find the initial publications of program graduates. A time-saving feature of Scopus is the periodic automatic alerts of new publications. Although a training period is needed and initial costs can be high, an automated search method is worthwhile due to its high sensitivity and efficiency in the long term.

    Boeker, Martin; Vach, Werner; Motschall, Edith

    2013-10-26

    Recent research indicates a high recall in Google Scholar searches for systematic reviews. These reports raised high expectations of Google Scholar as a unified and easy to use search interface. However, studies on the coverage of Google Scholar rarely used the search interface in a realistic approach but instead merely checked for the existence of gold standard references. In addition, the severe limitations of the Google Search interface must be taken into consideration when comparing with professional literature retrieval tools.The objectives of this work are to measure the relative recall and precision of searches with Google Scholar under conditions which are derived from structured search procedures conventional in scientific literature retrieval; and to provide an overview of current advantages and disadvantages of the Google Scholar search interface in scientific literature retrieval. General and MEDLINE-specific search strategies were retrieved from 14 Cochrane systematic reviews. Cochrane systematic review search strategies were translated to Google Scholar search expression as good as possible under consideration of the original search semantics. The references of the included studies from the Cochrane reviews were checked for their inclusion in the result sets of the Google Scholar searches. Relative recall and precision were calculated. We investigated Cochrane reviews with a number of included references between 11 and 70 with a total of 396 references. The Google Scholar searches resulted in sets between 4,320 and 67,800 and a total of 291,190 hits. The relative recall of the Google Scholar searches had a minimum of 76.2% and a maximum of 100% (7 searches). The precision of the Google Scholar searches had a minimum of 0.05% and a maximum of 0.92%. The overall relative recall for all searches was 92.9%, the overall precision was 0.13%. The reported relative recall must be interpreted with care. It is a quality indicator of Google Scholar confined to

    A thorough review of the literature is the basis of all research and evidence-based practice. A gold-standard efficient and exhaustive search strategy is needed to ensure all relevant citations have been captured and that the search performed is reproducible. The PubMed database comprises both the MEDLINE and non-MEDLINE databases. MEDLINE-based search strategies are robust but capture only 89% of the total available citations in PubMed. The remaining 11% include the most recent and possibly relevant citations but are only searchable through less efficient techniques. An effective search strategy must employ both the MEDLINE and the non-MEDLINE portion of PubMed to ensure all studies have been identified. The robust MEDLINE search strategies are used for the MEDLINE portion of the search. Usage of the less robust strategies is then efficiently confined to search only the remaining 11% of PubMed citations that have not been indexed for MEDLINE. The current article offers step-by-step instructions for building such a search exploring methods for the discovery of medical subject heading (MeSH) terms to search MEDLINE, text-based methods for exploring the non-MEDLINE database, information on the limitations of convenience algorithms such as the "related citations feature," the strengths and pitfalls associated with commonly used filters, the proper usage of Boolean operators to organize a master search strategy, and instructions for automating that search through "MyNCBI" to receive search query updates by email as new citations become available.

    Full Text Available Introduction. Evidence-Based Medicine (EBM is hurtling towards a cornerstone in lifelong learning for healthcare personnel worldwide. This study aims to evaluate the literature searching anxiety in graduate students in practicing EBM. Method The study participants were 48 graduate students who enrolled the EBM course at aMedical Universityin central Taiwan. Student’s t-test, Pearson correlation and multivariate regression, interviewing are used to evaluate the students’ literature searching anxiety of EBM course. The questionnaire is Literature Searching Anxiety Rating Scale -LSARS. Results The sources of anxiety are uncertainty of database selection, literatures evaluation and selection, technical assistance request, computer programs use, English and EBM education programs were disclosed. The class performance is negatively related to LSARS score, however, the correlation is statistically insignificant with the adjustment of gender, degree program, age category and experience of publication. Conclusion This study helps in understanding the causes and the extent of anxiety in order to work on a better teaching program planning to improve user’s searching skills and the capability of utilization the information; At the same time, provide friendly-user facilities of evidence searching. In short, we need to upgrade the learner’s searching 45 skills and reduce theanxiety. We also need to stress on the auxiliary teaching program for those with the prevalent and profoundanxiety during literature searching.

Based on a series of lectures by world experts in this field held at CERN, this volume provides a pedagogical introduction to the theory, cosmology and astrophysics of these fascinating particles and gives an up-to-date account of the status and prospect of ongoing and planned experimental searches. Learners and practitioners of astroparticle physics will find in this book both a concise introduction and a current reference work to a showcase topic that connects the "inner space" of the elementary particle world with the "outer space" of the universe at large. The book will be presented by Markus Kuster. "Axions: Theory, Cosmology, and Experimental Searches", edited by M. Kuster (Technische Universität Darmstadt), G. Raffelt (Max-Planck-Institu...

    Chapman, Andrea L; Morgan, Laura C; Gartlehner, Gerald

    2010-03-01

    To minimise retrieval bias, manual literature searches are a key part of the search process of any systematic review. Considering the need to have accurate information, valid results of the manual literature search are essential to ensure scientific standards; likewise efficient approaches that minimise the amount of personnel time required to conduct a manual literature search are of great interest. The objective of this project was to determine the validity and efficiency of a new manual search method that utilises the scopus database. We used the traditional manual search approach as the gold standard to determine the validity and efficiency of the proposed scopus method. Outcome measures included completeness of article detection and personnel time involved. Using both methods independently, we compared the results based on accuracy of the results, validity and time spent conducting the search, efficiency. Regarding accuracy, the scopus method identified the same studies as the traditional approach indicating its validity. In terms of efficiency, using scopus led to a time saving of 62.5% compared with the traditional approach (3 h versus 8 h). The scopus method can significantly improve the efficiency of manual searches and thus of systematic reviews.

    Medical literature searches provide critical information for clinicians. However, the best strategy for identifying relevant high-quality literature is unknown. We compared search results using PubMed and Google Scholar on four clinical questions and analysed these results with respect to article relevance and quality. Abstracts from the first 20 citations for each search were classified into three relevance categories. We used the weighted kappa statistic to analyse reviewer agreement and nonparametric rank tests to compare the number of citations for each article and the corresponding journals' impact factors. Reviewers ranked 67.6% of PubMed articles and 80% of Google Scholar articles as at least possibly relevant (P = 0.116) with high agreement (all kappa P-values Google Scholar articles had a higher median number of citations (34 vs. 1.5, P Google Scholar searches often identify different articles. In this study, Google Scholar articles were more likely to be classified as relevant, had higher numbers of citations and were published in higher impact factor journals. The identification of frequently cited articles using Google Scholar for searches probably has value for initial literature searches. © 2012 The authors.

    2008-03-01

    With increasing medical knowledge and emphasis upon evidence-based medicine, it is essential for practitioners to have optimal literature searching skills. There are limited data regarding the use of online information retrieval (IR) systems by paediatric junior medical officers (JMO). The aims of this questionnaire-based study of a group of JMO were to assess the accessibility, frequency of use and preferences for electronic information resources, and to ascertain their perceived adequacy of training and expertise in online searching. Questionnaires were distributed to 319 JMO at two Australian children's hospitals. A total of 106 questionnaires were returned (33.2% response rate). Twenty-four-hour access to electronic medical databases was available to almost 90% of respondents at work or home. Five or less online searches per month were performed by 53.7% of respondents. Previous formal training in database searching was reported by 72.4% of respondents, but over half felt it had been inadequate. Most JMO (91.5%) acknowledged a need for further training in search skills. In spite of widespread availability of online resources, use of these resources was sub-optimal in this group of trainee doctors. Most respondents reported a need for further training in electronic searching. Continuing targeted education in electronic database searching is required to ensure that future doctors develop skills to ensure optimal use of medical literature.

    This paper describes on-going research on streamlining the access and use of spatial data and processes in Australia. Spatial data in Australia is available on-line at many levels of government from local authorities, state and territories (jurisdictions), and nationally from the Commonwealth and other sources. Much of this data is available via Open Geospatial Consortium and World Wide Web Consortium standard web services. This abstract discusses three related research topics that have been identified by a wide range of stakeholders through a comprehensive consultation process. These are search and discovery, federation and orchestration of data and processes. The commonality across the three research topics is that they all require Semantic Web and Artificial Intelligence methods and embrace the various standards, and if needed, propose modifications to such standards.

    To determine the optimal databases to search for studies of faith-sensitive interventions for treating depression. We examined 23 health, social science, religious, and grey literature databases searched for an evidence synthesis. Databases were prioritized by yield of (1) search results, (2) potentially relevant references identified during screening, (3) included references contained in the synthesis, and (4) included references that were available in the database. We assessed the impact of databases beyond MEDLINE, EMBASE, and PsycINFO by their ability to supply studies identifying new themes and issues. We identified pragmatic workload factors that influence database selection. PsycINFO was the best performing database within all priority lists. ArabPsyNet, CINAHL, Dissertations and Theses, EMBASE, Global Health, Health Management Information Consortium, MEDLINE, PsycINFO, and Sociological Abstracts were essential for our searches to retrieve the included references. Citation tracking activities and the personal library of one of the research teams made significant contributions of unique, relevant references. Religion studies databases (Am Theo Lib Assoc, FRANCIS) did not provide unique, relevant references. Literature searches for reviews and evidence syntheses of religion and health studies should include social science, grey literature, non-Western databases, personal libraries, and citation tracking activities.

    Hamed, Ahmed Abdeen; Wu, Xindong; Erickson, Robert; Fandy, Tamer

    2015-08-01

    The importance of searching biomedical literature for drug interaction and side-effects is apparent. Current digital libraries (e.g., PubMed) suffer infrequent tagging and metadata annotation updates. Such limitations cause absence of linking literature to new scientific evidence. This demonstrates a great deal of challenges that stand in the way of scientists when searching biomedical repositories. In this paper, we present a network mining approach that provides a bridge for linking and searching drug-related literature. Our contributions here are two fold: (1) an efficient algorithm called HashPairMiner to address the run-time complexity issues demonstrated in its predecessor algorithm: HashnetMiner, and (2) a database of discoveries hosted on the web to facilitate literature search using the results produced by HashPairMiner. Though the K-H network model and the HashPairMiner algorithm are fairly young, their outcome is evidence of the considerable promise they offer to the biomedical science community in general and the drug research community in particular.

    Full Text Available Abstract Background Palliative care is an evolving specialty with a growing evidence base. However, evidence is less accessible than it could be with a lower than average conversion of conference abstracts to articles in peer-reviewed journals and the need for more accessible tools to support evidence-based practice (EBP in palliative care. The CareSearch project involved identifying, collecting and evaluating Australia's "grey" palliative care literature and identifying international published literature missing from the electronic indexing systems. The literature was then catalogued and made publicly available through the CareSearch website. Results To date over 2,500 items have been included in the CareSearch database and can be accessed and searched through a publicly available website. Nearly 2,000 items are conference abstracts and 178 are theses or government, organisational and planning documents. A further 410 items relate to articles from palliative journals that are not indexed on a major bibliographic database. The website also provides tools and facilities to support palliative care practice and research. Conclusion CareSearch is a new evidence resource for palliative practitioners, educators and researchers. The palliative community now has access to a more comprehensive literature base as well as a resource that supports the integration of knowledge into practice. This specialised data repository enables users to access information on the body of work that has shaped palliative care development and prevents the potential loss or duplication of research work. It also provides a template for other emerging disciplines to use in capturing their literature and evidence.

    2000-03-01

    Full Text Available Fiscal federalism theory seeks to establish the optimal organization of a government, confined by certain geographic boundaries. The implications of that theory for the monetary unification process are shortly inquired. The literature measuring the redistribution and stabilization effects of the tax and transfer systems in different monetary unions is surveyed. The prospects of evolution to integration models with a federalist countenance are briefly analysed and it is given special attention to the projects of creation of a European Fiscal Transfers Scheme. That mechanism would provide the European economies with some degree of stabilization in substitution for the loss of the adjustment mechanisms. However, after analysing the different proposals for the creation of such mechanism we conclude that, given the shocks persistence, they easily become redistribution mechanisms.

  13. “Brimful of STARLITE”: toward standards for reporting literature searches

    Science.gov (United States)

    Booth, Andrew

    2006-01-01

    Context: Systematic reviews of qualitative research studies extend understanding of health care beyond effectiveness to acceptability and user views. Objective: The paper surveys reports of qualitative systematic reviews and, by characterizing techniques used to identify articles for inclusion, proposes standards for reporting of literature searches. Data Sources and Study Selection: A search of MEDLINE was performed for qualitative systematic reviews published from 1988 to December 2004, supported by searches of CINAHL, Web of Knowledge (including the Science and Social Sciences Citation Index), and the Cochrane Methodology Register, and Internet searches using the Copernic Agent Professional meta-search agent. Studies were included if they used techniques of qualitative synthesis in reviewing research studies in health care. Narrative reviews were excluded. Data Extraction: Authors, year of publication, sampling strategy, databases, keywords, and other approaches used were extracted. Data Synthesis: Sixty-four studies were identified, and forty-three met inclusion criteria for this review. A summary of searching methods was produced and used to construct the STARLITE mnemonic (sampling strategy, type of study, approaches, range of years, limits, inclusion and exclusions, terms used, electronic sources). Conclusions: Considerable variation exists in search methods for qualitative systematic reviews. While diversity in methods is appropriate during the development of review methodology, major concerns remain about the absence of an accepted standard and the consequent poor quality of reporting.

    Taylor, Donald P

    2007-01-01

    High content screening (HCS) requires time-consuming and often complex iterative information retrieval and assessment approaches to optimally conduct drug discovery programs and biomedical research. Pre- and post-HCS experimentation both require the retrieval of information from public as well as proprietary literature in addition to structured information assets such as compound libraries and projects databases. Unfortunately, this information is typically scattered across a plethora of proprietary bioinformatics tools and databases and public domain sources. Consequently, single search requests must be presented to each information repository, forcing the results to be manually integrated for a meaningful result set. Furthermore, these bioinformatics tools and data repositories are becoming increasingly complex to use; typically they fail to allow for more natural query interfaces. Vivisimo has developed an enterprise software platform to bridge disparate silos of information. The platform automatically categorizes search results into descriptive folders without the use of taxonomies to drive the categorization. A new approach to information retrieval for HCS experimentation is proposed.

    As the volume of publications rapidly increases, searching for relevant information from the literature becomes more challenging. To complement standard search engines such as PubMed, it is desirable to have an advanced search tool that directly returns relevant biomedical entities such as targets, drugs, and mutations rather than a long list of articles. Some existing tools submit a query to PubMed and process retrieved abstracts to extract information at query time, resulting in a slow response time and limited coverage of only a fraction of the PubMed corpus. Other tools preprocess the PubMed corpus to speed up the response time; however, they are not constantly updated, and thus produce outdated results. Further, most existing tools cannot process sophisticated queries such as searches for mutations that co-occur with query terms in the literature. To address these problems, we introduce BEST, a biomedical entity search tool. BEST returns, as a result, a list of 10 different types of biomedical entities including genes, diseases, drugs, targets, transcription factors, miRNAs, and mutations that are relevant to a user's query. To the best of our knowledge, BEST is the only system that processes free text queries and returns up-to-date results in real time including mutation information in the results. BEST is freely accessible at http://best.korea.ac.kr.

    2017-09-04

    There is a lack of information on how to execute effective searches of the grey literature on refugee and asylum seeker groups for inclusion in systematic reviews. High-quality government reports and other grey literature relevant to refugees may not always be identified in conventional literature searches. During the process of conducting a recent systematic review, we developed a novel strategy for systematically searching international refugee and asylum seeker-related grey literature. The approach targets governmental health departments and statistical agencies, who have considerable access to refugee and asylum seeker populations for research purposes but typically do not publish findings in academic forums. Compared to a conventional grey literature search strategy, our novel technique yielded an eightfold increase in relevant high-quality grey sources that provided valuable content in informing our review. Incorporating a search of the grey literature into systematic reviews of refugee and asylum seeker research is essential to providing a more complete view of the evidence. Our novel strategy offers a practical and feasible method of conducting systematic grey literature searches that may be adaptable to a range of research questions, contexts, and resource constraints.

  19. Beyond PubMed: Searching the "Grey Literature" for Clinical Trial Results.

    Science.gov (United States)

    Citrome, Leslie

    2014-07-01

    Clinical trial results have been traditionally communicated through the publication of scholarly reports and reviews in biomedical journals. However, this dissemination of information can be delayed or incomplete, making it difficult to appraise new treatments, or in the case of missing data, evaluate older interventions. Going beyond the routine search of PubMed, it is possible to discover additional information in the "grey literature." Examples of the grey literature include clinical trial registries, patent databases, company and industrywide repositories, regulatory agency digital archives, abstracts of paper and poster presentations on meeting/congress websites, industry investor reports and press releases, and institutional and personal websites.

    2011-04-01

    The objective of this study was to assess the risk factors for bladder cancer using PubMed articles from January 2000 to December 2009. The study also aimed to describe the challenges encountered in the methodology of a literature search for bladder cancer risk factors using PubMed. Twenty-six categories of risk factors for bladder cancer were identified using the National Cancer Institute Web site and the Medical Subject Headings (MeSH) Web site. A total of 1,338 PubMed searches were run using the term "urinary bladder cancer" and a risk factor term (e.g., "cigarette smoking") and were screened to identify 260 articles for final analysis. The search strategy had an overall precision of 3.42 percent, relative recall of 12.64 percent, and an F-measure of 5.39 percent. Although search terms derived from MeSH had the highest overall precision and recall, the differences did not reach significance, which indicates that for generalized, free-text searches of the PubMed database, the searchers' own terms are generally as effective as MeSH terms.

GeneLab is currently being developed by NASA to support Open Science biomedical research in order to enable the human exploration of space and improve life on earth. Open access to Phase 1 of the GeneLab Data Systems (GLDS) was implemented in April 2015. Download volumes have grown steadily, mirroring the growth in curated space biology research data sets (61 as of June 2016), now exceeding 10 TB/month, with over 10,000 file downloads since the start of Phase 1. For the period April 2015 to May 2016, most frequently downloaded were data from studies of Mus musculus (39) followed closely by Arabidopsis thaliana (30), with the remaining downloads roughly equally split across 12 other organisms (each 10 of total downloads). GLDS Phase 2 is focusing on interoperability, supporting data federation, including integrated search capabilities, of GLDS-housed data sets with external data sources, such as gene expression data from NIHNCBIs Gene Expression Omnibus (GEO), proteomic data from EBIs PRIDE system, and metagenomic data from Argonne National Laboratory's MG-RAST. GEO and MG-RAST employ specifications for investigation metadata that are different from those used by the GLDS and PRIDE (e.g., ISA-Tab). The GLDS Phase 2 system

    Quantifying scientific relevancy is of increasing importance to NASA and the research community. Scientific relevancy may be defined by mapping the impacts of a particular NASA mission, instrument, and/or retrieved variables to disciplines such as climate predictions, natural hazards detection and mitigation processes, education, and scientific discoveries. Related to relevancy, is the ability to expose data with similar attributes. This in turn depends upon the ability for us to extract latent, implicit document features from scientific data and resources and make them explicit, accessible and useable for search activities amongst others. This paper presents MemexGATE; a server side application, command line interface and computing environment for running large scale metadata extraction, general architecture text engineering, document classification and indexing tasks over document resources such as social media streams, scientific literature archives, legal documentation, etc. This work builds on existing experiences using MemexGATE (funded, developed and validated through the DARPA Memex Progrjam PI Mattmann) for extracting and leveraging latent content features from document resources within the Materials Research domain. We extend the software functionality capability to the domain of scientific literature with emphasis on the expansion of gazetteer lists, named entity rules, natural language construct labeling (e.g. synonym, antonym, hyponym, etc.) efforts to enable extraction of latent content features from data hosted by wide variety of scientific literature vendors (AGU Meeting Abstract Database, Springer, Wiley Online, Elsevier, etc.) hosting earth science literature. Such literature makes both implicit and explicit references to NASA datasets and relationships between such concepts stored across EOSDIS DAAC's hence we envisage that a significant part of this effort will also include development and understanding of relevancy signals which can ultimately

    PubMed and HighWire Press are both useful medical literature search engines available for free to anyone on the internet. We measured retrieval accuracy, number of results generated, retrieval speed, features and search tools on HighWire Press and PubMed using the quick search features of each. We found that using HighWire Press resulted in a higher likelihood of retrieving the desired article and higher number of search results than the same search on PubMed. PubMed was faster than HighWire Press in delivering search results regardless of search settings. There are considerable differences in search features between these two search engines.

    Full Text Available BACKGROUND: Providing psychological first aid (PFA is generally considered to be an important element in preliminary care of disaster victims. Using the best available scientific basis for courses and educational materials, the Belgian Red Cross-Flanders wants to ensure that its volunteers are trained in the best way possible. OBJECTIVE: To identify effective PFA practices, by systematically reviewing the evidence in existing guidelines, systematic reviews and individual studies. METHODS: Systematic literature searches in five bibliographic databases (MEDLINE, PsycINFO, The Cochrane Library, PILOTS and G-I-N were conducted from inception to July 2013. RESULTS: Five practice guidelines were included which were found to vary in the development process (AGREE II score 20-53% and evidence base used. None of them provides solid evidence concerning the effectiveness of PFA practices. Additionally, two systematic reviews of PFA were found, both noting a lack of studies on PFA. A complementary search for individual studies, using a more sensitive search strategy, identified 11 237 references of which 102 were included for further full-text examination, none of which ultimately provides solid evidence concerning the effectiveness of PFA practices. CONCLUSION: The scientific literature on psychological first aid available to date, does not provide any evidence about the effectiveness of PFA interventions. Currently it is impossible to make evidence-based guidelines about which practices in psychosocial support are most effective to help disaster and trauma victims.

  11. GoEarth - performance and challenges of a semantic search engine for CCS literature

    Increased interests in climate sciences have led to exponentially increasing publication numbers regarding Carbon Capture and Storage (CCS). In order to be able to handle this overload of information, an ontology-based, semantic search system was developed. The used ontology was especially designed for geo-scientific content in CCS-literature. The semantic search engine provides users with an infrastructure that semantically categorizes textual content by facilitating natural language processing for the knowledge domain of CCS. The system works fully automated. So even search without keywords becomes possible and documents can be identified by navigating the ontology which is rendered as a tree on the left hand side of the search results. Furthermore, meta-data analysis provides useful statistical information, e.g. about author networks. Compared to the 1045 AGU index terms and the 3587 GeoRef thesaurus terms, the new CCS ontology (1170 concepts and synonyms) links to 11.0 % and 8.6 % more documents of a geo-scientific text corpus, respectively. Of all test documents, the CCS ontology hits 96.5 % (GeoRef: 88.9 %, AGU index terms: 87.1 %). We will discuss existing challenges like disambiguation of concepts and intelligent text mining.

    The medical education literature is growing, and the result is not only greater knowledge, but an increasing complexity in locating quality evidence-based information. In 2008, eight librarians partnered with the Association of American Medical Colleges to research, conceptualize, and build an online module to develop medical educators' search skills. Developing an online instructional module is a time-consuming, multi-stage process requiring the expertise of content, technical, and design specialists working in concert. Many lessons were learned, including the power of collaborative tools; the benefits of including specialists, such as graphic designers; the benefit of thoroughly surveying existing resources; and the importance of choosing technology wisely.

    As the importance of systematic review (SR) conclusions relies upon the scientific rigor of methods and the currency of evidence, we aimed to investigate the currency of orthodontic SRs using as proxy the time from the initial search to publication. Additionally, SR information regarding reporting guidelines, registration, and literature searches were recorded when available. A systematic PubMed search was carried out using the Clinical Queries page to identify orthodontic SRs cited between 1 January 2008 and 7 November 2013. Data related to reporting guidelines, review registration, dates of review processing, literature search, and abstract reporting were retrieved and classified by journal type. Survival analysis was used to assess the time to reach predefined manuscript stages for orthodontic and non-orthodontic journals. One hundred twenty seven of the originally identified 585 SRs were considered eligible. The median interval from search until publication was 13.2 months (interquartile range: IQR = 9.7 months) irrespective of the journal type. There was evidence (P = 0.05) that SRs published by non-orthodontic journals appeared in PubMed faster than in orthodontic journals (non-orthodontic: median = 6.5 months; IQR = 5.7 months; orthodontic: median = 10.2 months; IQR = 5.6 months) from submission to publication and from acceptance to publication (non-orthodontic: median = 1.5 months; IQR = 2.4 months; orthodontic: median = 6.0 months; IQR = 6.2 months; P orthodontic and orthodontic periodicals, respectively. This study indicates that SR users should be aware that median time for orthodontic SRs from search to publication is 13.2 months. SRs published in non-orthodontic journals are likely to be more current in terms of submission until time to publication and acceptance until time to publication compared with those published in orthodontic journals. © The Author 2014.

    2015-01-01

    Manual curation of biomedical literature has become extremely tedious process due to its exponential growth in recent years. To extract meaningful information from such large and unstructured text, newer and more efficient mining tool is required. Here, we introduce PALM-IST, a computational platform that not only allows users to explore biomedical abstracts using keyword based text mining but also extracts biological entity (e.g., gene/protein, drug, disease, biological processes, cellular component, etc.) information from the extracted text and subsequently mines various databases to provide their comprehensive inter-relation (e.g., interaction, expression, etc.). PALM-IST constructs protein interaction network and pathway information data relevant to the text search using multiple data mining tools and assembles them to create a meta-interaction network. It also analyzes scientific collaboration by extraction and creation of “co-authorship network,” for a given search context. Hence, this useful combination of literature and data mining provided in PALM-IST can be used to extract novel protein-protein interaction (PPI), to generate meta-pathways and further to identify key crosstalk and bottleneck proteins. PALM-IST is available at www.hpppi.iicb.res.in/ctm. PMID:25989388

    To extract disorder-associated genes from the scientific literature in PubMed with greater sensitivity for literature-based support than existing methods. We developed a PubMed query to retrieve disorder-related, original research articles. Then we applied a rule-based text-mining algorithm with keyword matching to extract target disorders, genes with significant results, and the type of study described by the article. We compared our resulting candidate disorder genes and supporting references with existing databases. We demonstrated that our candidate gene set covers nearly all genes in manually curated databases, and that the references supporting the disorder-gene link are more extensive and accurate than other general purpose gene-to-disorder association databases. We implemented a novel publication search tool to find target articles, specifically focused on links between disorders and genotypes. Through comparison against gold-standard manually updated gene-disorder databases and comparison with automated databases of similar functionality we show that our tool can search through the entirety of PubMed to extract the main gene findings for human diseases rapidly and accurately.

    Objectives To summarise existing evidence on a target oriented approach for rheumatoid arthritis (RA) treatment. Methods We conducted a systematic literature search including all clinical trials testing clinical, functional, or structural values of a targeted treatment approach. Our search covered Medline, Embase and Cochrane databases until December 2008 and also conference abstracts (2007, 2008). Results The primary search yielded 5881 citations; after the selection process, 76 papers underwent detailed review. Of these, only seven strategic clinical trials were extracted: four studies randomised patients to routine or targeted treatment, two compared two different randomised targets and one compared targeted treatment to a historical control group. Five trials dealt with early RA patients. All identified studies showed significantly better clinical outcomes of targeted approaches than routine approaches. Disability was reported in two studies with no difference between groups. Four studies compared radiographic outcomes, two showing significant benefit of the targeted approach. Conclusion Only few studies employed randomised controlled settings to test the value of treatment to a specific target. However, they provided unanimous evidence for benefits of targeted approaches. Nevertheless, more data on radiographic and functional outcomes and on patients with established RA are needed. PMID:20237123

    During the next several decades, the US Department of Energy is expected to spend tens of billions of dollars in the characterization, cleanup, and monitoring of DOE`s current and former installations that have various degrees of soil and groundwater contamination made up of both hazardous and mixed wastes. Each of these phases will require site surveys to determine type and quantity of hazardous and mixed wastes. It is generally recognized that these required survey and monitoring efforts cannot be performed using traditional chemistry methods based on laboratory evaluation of samples from the field. For that reason, a tremendous push during the past decade or so has been made on research and development of sensors. This report contains the results of an extensive literature search on sensors that are used or have applicability in environmental and waste management. While restricting the search to a relatively small part of the total chemistry spectrum, a sizable body of reference material is included. Results are presented in tabular form for general references obtained from data base searches, as narrative reviews of relevant chapters from proceedings, as book reviews, and as reviews of journal articles with particular relevance to the review. Four broad sensor types are covered: electrochemical processes, piezoelectric devices, fiber optics, and radiochemical processes. The topics of surface chemistry processes and biosensors are not treated separately because they often are an adjunct to one of the four sensors listed. About 1,000 tabular entries are listed, including selected journal articles, reviews of conference/meeting proceedings, and books. Literature to about mid-1992 is covered.

The first session introduced participants to basic Boolean searching (using AND only, selecting appropriate keywords and searching for books in the library catalogue. In the second library session, students were handed an evaluation worksheet and, with no introduction to the process of searching article databases, were asked to find relevant articles on a research topic of their own choosing using both a federated search tool and a single multidisciplinary database. The evaluation worksheet was divided into four sections: step-by-step instructions for accessing the single multidisciplinary database and the federated search tool; space to record search strings in both resources; space to record the titles of up to five relevant articles; and a series of quantitative and qualitative questions regarding ease-of-use, relevancy of results, overall preference (if any between the two resources, likeliness of future use and other preferred research tools. Half of the participants received a worksheet with instructions to search the federated search tool before the single database; the order was reversed for the other half of the students. The evaluation worksheet was designed to be completed in one hour.Participant responses to qualitative questions were analyzed, codified and grouped into thematic categories. If a student mentioned more than one factor in responding to a question, their response was recorded in multiple categories.Main Results

    Complete access to the existing pool of biomedical literature and the ability to "hit" upon the exact information of the relevant specialty are becoming essential elements of academic and clinical expertise. With the rapid expansion of the literature database, it is almost impossible to keep up to date with every innovation. Using the Internet, however, most people can freely access this literature at any time, from almost anywhere. This paper highlights the use of the Internet in obtaining valuable biomedical research information, which is mostly available from journals, databases, textbooks and e-journals in the form of web pages, text materials, images, and so on. The authors present an overview of web-based resources for biomedical researchers, providing information about Internet search engines (e.g., Google), web-based bibliographic databases (e.g., PubMed, IndMed) and how to use them, and other online biomedical resources that can assist clinicians in reaching well-informed clinical decisions.

    Objective The research evaluated the perceived quality of librarian-mediated literature searching services at one of Canada’s largest acute care teaching hospitals for the purpose of continuous quality improvement and investigation of relationships between variables that can impact user satisfaction. Methods An online survey was constructed using evidence-based methodologies. A systematic sample of staff and physicians requesting literature searches at London Health Sciences Centre were invited to participate in the study over a one-year period. Data analyses included descriptive statistics of closed-ended questions and coding of open-ended questions. Results A range of staff including clinicians, researchers, educators, leaders, and analysts submitted a total of 137 surveys, representing a response rate of 71%. Staff requested literature searches for the following “primary” purposes: research or publication (34%), teaching or training (20%), informing a policy or standard practice (16%), patient care (15%), and “other” purposes (15%). While the majority of staff (76%) submitted search requests using methods of written communication, including email and search request forms, staff using methods of verbal communication, including face-to-face and telephone conversations, were significantly more likely to be extremely satisfied with the librarian’s interpretation of the search request (p=0.004) and to rate the perceived quality of the search results as excellent (p=0.005). In most cases, librarians followed up with staff to clarify the details of their search requests (72%), and these staff were significantly more likely to be extremely satisfied with the librarian’s interpretation of the search request (p=0.002). Conclusions Our results demonstrate the limitations of written communication in the context of librarian-mediated literature searching and suggest a multifaceted approach to quality improvement efforts.

    This article is the fourth of six articles addressing systematic reviews in animal agriculture and veterinary medicine. Previous articles in the series have introduced systematic reviews, discussed study designs and hierarchies of evidence, and provided details on conducting randomized controlled trials, a common design for use in systematic reviews. This article describes development of a review protocol and the first two steps in a systematic review: formulating a review question, and searching the literature for relevant research. The emphasis is on systematic reviews of questions related to interventions. The review protocol is developed prior to conducting the review and specifies the plan for the conduct of the review, identifies the roles and responsibilities of the review team and provides structured definitions related to the review question. For intervention questions, the review question should be defined by the PICO components: population, intervention, comparison and outcome(s). The literature search is designed to identify all potentially relevant original research that may address the question. Search terms related to some or all of the PICO components are entered into literature databases, and searches for unpublished literature also are conducted. All steps of the literature search are documented to provide transparent reporting of the process. © 2014 Blackwell Verlag GmbH.

    The use of search filters (e. g. for study types) facilitates the process of literature searching. Regional limits might be helpful depending on the research question. Regional search filters are already available for some regions, but not for Germany. Our aim is to give an overview of applied search strategies in systematic reviews (SRs) focusing on Germany. We searched Medline (via Pubmed) applying a focused search strategy to identify SRs focusing on Germany in January 2016. Study selection and data extraction were performed by two reviewers independently. The search strategies with a focus on Germany were analyzed in terms of reasonableness and completeness relying on the Peer Review of Electronic Search Strategies (PRESS) criteria. A narrative evidence synthesis was performed. In total, 36 SRs (13 written in English) were included. 78% were published in 2012 or later. The majority (89%) of SRs utilized at least two different sources for their search with databases and checking references being the most common. 17 SRs did not use any truncations, ten SRs did not restrict their search to Germany, six SRs reported to have searched for German OR Germany. Only ten articles searched for the term Germany (occasionally jointly with the term Deutschland) without any use of an adjective such as German. There is a high interest in regionally focused SRs. The identified search strategies revealed a need for improvement. It would be helpful to develop a regional search filter for Germany that is able to identify studies performed in Germany.

    Simple Summary The emotional lives of animals is often doubted and questioned. Due to the subjective nature of animal emotions, many think that they are out of the reach of scientific measurement. In this systematic review, of over two decades of scientific literature, we found that this was not actually the case. By using a list of keywords, formed of both positive and negative emotions, and terminology relating to animal sentience, we reviewed the scientific literature. We found that the subjective lives of animals are not only a vital part of human medical research but are regularly measured and studied with scientific rigor. Abstract Knowledge of animal sentience is fundamental to many disciplines and imperative to the animal welfare movement. In this review, we examined what is being explored and discussed, regarding animal sentience, within the scientific literature. Rather than attempting to extract meaning from the many complex and abstract definitions of animal sentience, we searched over two decades of scientific literature using a peer-reviewed list of 174 keywords. The list consisted of human emotions, terminology associated with animal sentience, and traits often thought to be indicative of subjective states. We discovered that very little was actually being explored, and instead there was already much agreement about what animals can feel. Why then is there so much scepticism surrounding the science of animal sentience? Sentience refers to the subjective states of animals, and so is often thought to be impossible to measure objectively. However, when we consider that much of the research found to accept and utilise animal sentience is performed for the development of human drugs and treatment, it appears that measuring sentience is, after all, not quite as impossible as was previously thought. In this paper, we explored what has been published on animal sentience in the scientific literature and where the gaps in research lie. We drew conclusions on

    Full Text Available Objective – The study aimed to develop a search protocol and evaluate reviewers' satisfaction with an evidence-based practice (EBP review by embedding a library science student in the process.Methods – The student was embedded in one of four review teams overseen by a professional organization for oncology nurses (ONS. A literature search protocol was developed by the student following discussion and feedback from the review team. Organization staff provided process feedback. Reviewers from both case and control groups completed a questionnaire to assess satisfaction with the literature search phases of the review process. Results – A protocol was developed and refined for use by future review teams. The collaboration and the resulting search protocol were beneficial for both the student and the review team members. The questionnaire results did not yield statistically significant differences regarding satisfaction with the search process between case and control groups. Conclusions – Evidence-based reviewers' satisfaction with the literature searching process depends on multiple factors and it was not clear that embedding an LIS specialist in the review team improved satisfaction with the process. Future research with more respondents may elucidate specific factors that may impact reviewers' assessment.

    The Authors, who in 1977 published the first Italian case report of the Nicolau syndrome (N.S.) from penicillin preparations in the pediatric field, accomplished a thorough search for similar reports in the world literature finding a total of 102 cases, of whom 80 were less than 12-year old. They made a detailed analysis of each case in that series in order to identify or better define potential risk factors or predisposing circumstances worth being taken in consideration for preventive purposes. Indeed, the possible occurrence of N.S., which may include devastating complications such as limb gangrene, paraplegia, or death and have medico-legal implications, is still largely underrated or unrecognised by both physicians and nurses. It is unfortunate in particular that no acknowledgement of that syndrome is available in the teaching programs and textbooks used in professional nurse schools; in addition physicians are not enough zealous in discouraging unqualified lified people as well as patient's relatives from performing intramuscular injections, mainly using certain kinds of drugs such as crystalline suspensions. On the basis of the findings of their analysis as well as of an overall review of the relevant literature the Authors conclude their paper by making a series of specific recommendations and/or proposals addressed to the various operators involved in the matter (prescribing physicians, managers of nursing schools, nurses, pharmaceutical companies, Regulatory Health Authority), with special emphasis on the precautionary measures to be taken in doing intramuscular injection of long-acting penicillins or other drugs in crystalline suspension.

    Objective A systematic literature review (SLR; 2009–2014) to compare a target-oriented approach with routine management in the treatment of rheumatoid arthritis (RA) to allow an update of the treat-to-target recommendations. Methods Two SLRs focused on clinical trials employing a treatment approach targeting a specific clinical outcome were performed. In addition to testing clinical, functional and/or structural changes as endpoints, comorbidities, cardiovascular risk, work productivity and education as well as patient self-assessment were investigated. The searches covered MEDLINE, EMBASE, Cochrane databases and Clinicaltrial.gov for the period between 2009 and 2012 and separately for the period of 2012 to May of 2014. Results Of 8442 citations retrieved in the two SLRs, 176 articles underwent full-text review. According to predefined inclusion/exclusion criteria, six articles were included of which five showed superiority of a targeted treatment approach aiming at least at low-disease activity versus routine care; in addition, publications providing supportive evidence were also incorporated that aside from expanding the evidence provided by the above six publications allowed concluding that a target-oriented approach leads to less comorbidities and cardiovascular risk and better work productivity than conventional care. Conclusions The current study expands the evidence that targeting low-disease activity or remission in the management of RA conveys better outcomes than routine care. PMID:25990290

    Regulatory guidelines require that any new medicine designed for a pediatric population must be demonstrated as being acceptable to that population. There is currently no guidance on how to conduct or report on acceptability testing. Our objective was to undertake a review of the methods used to assess the acceptability of medicines within a pediatric population and use this review to propose the most appropriate methodology. We used a defined search strategy to identify literature reports of acceptability assessments of medicines conducted within pediatric populations and extracted information about the tools used in these studies for comparison across studies. In total, 61 articles were included in the analysis. Palatability was the most common (54/61) attribute measured when evaluating acceptability. Simple scale methods were most commonly used, with visual analog scales (VAS) and hedonic scales used both separately and in combination in 34 of the 61 studies. Hedonic scales alone were used in 14 studies and VAS alone in just five studies. Other tools included Likert scales; forced choice or preference; surveys or questionnaires; observations of facial expressions during administration, ease of swallowing, or ability to swallow the dosage; prevalence of complaints or refusal to take the medicine; and time taken for a nurse to administer the medicine. The best scale in terms of validity, reliability, feasibility, and preference to use when assessing acceptability remains unclear. Further work is required to select the most appropriate method to justify whether a medicine is acceptable to a pediatric population.

  19. Paranormal phenomena in the medical literature sufficient smoke to warrant a search for fire.

    Science.gov (United States)

    Bobrow, Robert S

    2003-06-01

    Paranormal phenomena - events that cannot be explained by existing science - are regularly reported in medicine. Surveys have shown that a majority of the population of the United States and Great Britain hold at least one paranormal belief. Information was retrieved by MEDLINE searches using keywords 'paranormal' and 'psychic', and from the author's own collection. Reports are predominantly by physicians, and from peer-reviewed, MEDLINE-indexed literature. This is a representative sample, as there is no database for paranormal medical phenomena. Presented and discussed are: a case of systemic lupus erythematosis ameliorated by witchcraft; an analysis of studies on distant healing; acupuncture, as a bridge between what is now accepted but recently would have been deemed paranormal; a carefully-done study of a psychic; auditory hallucinations informing a patient, correctly, that she had a brain tumor; two nearly-identical lay press reports of self-predicted death; lycanthropy (the delusion of being an animal); the development of Carl Jung's collective unconscious; hypnosis - still questioned despite documented therapeutic benefit, and a well-researched report of a person speaking a foreign language, apparently unlearned (xenoglossy) while hypnotized; and multiple examples of children who spout the details of the life of an unknown, deceased person. The inability of existing paradigms to explain these observations does not negate them; rather, it elucidates a need for more research.

  20. 6-Mercaptopurine for Azathioprine Intolerant Inflammatory Bowel Disease: Literature Search and Reappraisal of Own Data.

    2015-01-01

    Thiopurines have been shown to effectively maintain remission of both Crohn's disease (CD) and ulcerative colitis (UC), and to behave as disease modifiers if used for >12 months in UC. Gastric intolerance manifesting as nausea constitutes a demanding drawback of thiopurines, at times forcing treatment discontinuance. A few studies have now indicated that some patients might tolerate mercaptopurine (6-MP) for azathioprine. In this paper, we review the literature, and reappraise our own data against the published figures. The data which form the basis for this study span over all visit reports that were released between January 2008 and December 2011 in a primary care Hospital, in Turin, Italy. For the aim of this study we searched our own database and the MedLine using the key-words "azathioprine", "mercaptopurine", "thiopurine", "inflammatory bowel disease", "Crohn's disease", "ulcerative colitis". We retrieved 85 azathioprine prescriptions for 42 UC, 37 CD, and 6 miscellaneous patients. There were 10 episodes of gastric intolerance to azathioprine, which were switched to 6-MP: 6 out of 10 (60%) responded and tolerated the switch drug in a median follow-up of 66 months. Female gender prevailed (p=0.038) in the azathioprine intolerant subset. A trial with 6-MP is worth being offered to azathioprine intolerant inflammatory bowel disease subjects at any center matching the standard figures of specific performance.

  1. Muscle Logic: New Knowledge Resource for Anatomy Enables Comprehensive Searches of the Literature on the Feeding Muscles of Mammals.

    Directory of Open Access Journals (Sweden)

    Robert E Druzinsky

    Full Text Available In recent years large bibliographic databases have made much of the published literature of biology available for searches. However, the capabilities of the search engines integrated into these databases for text-based bibliographic searches are limited. To enable searches that deliver the results expected by comparative anatomists, an underlying logical structure known as an ontology is required.Here we present the Mammalian Feeding Muscle Ontology (MFMO, a multi-species ontology focused on anatomical structures that participate in feeding and other oral/pharyngeal behaviors. A unique feature of the MFMO is that a simple, computable, definition of each muscle, which includes its attachments and innervation, is true across mammals. This construction mirrors the logical foundation of comparative anatomy and permits searches using language familiar to biologists. Further, it provides a template for muscles that will be useful in extending any anatomy ontology. The MFMO is developed to support the Feeding Experiments End-User Database Project (FEED, https://feedexp.org/, a publicly-available, online repository for physiological data collected from in vivo studies of feeding (e.g., mastication, biting, swallowing in mammals. Currently the MFMO is integrated into FEED and also into two literature-specific implementations of Textpresso, a text-mining system that facilitates powerful searches of a corpus of scientific publications. We evaluate the MFMO by asking questions that test the ability of the ontology to return appropriate answers (competency questions. We compare the results of queries of the MFMO to results from similar searches in PubMed and Google Scholar.Our tests demonstrate that the MFMO is competent to answer queries formed in the common language of comparative anatomy, but PubMed and Google Scholar are not. Overall, our results show that by incorporating anatomical ontologies into searches, an expanded and anatomically comprehensive

    Biomedical databases are an important source of information for health technology assessment. However, there is considerable variation in the costs of accessing commercial databases. We sought to measure the quality, amount of overlap, and costs of information retrieved from two of the main database sources--MEDLINE and EMBASE. Librarians at two health technology assessment agencies ran a total of eight literature searches on various medical technologies, using both databases. All search results were independently reviewed by two researchers. The researchers were asked to identify relevant references and to rank each of these according to a level of evidence scale. The results were tabulated to show the number of references identified by each database, the number of relevant references ranked by level of evidence, and the number of these references that were unique to one or the other database. The cost of retrieving references from each source was also calculated. Each database contained relevant references not available in the other. Because of the longer time lag for indexing in MEDLINE, many of the references that originally appeared to be unique to EMBASE were subsequently available in MEDLINE as well. Since our study was conducted, MEDLINE has been made available worldwide, free of charge, via the Internet. Hence, the cost difference between the databases is now even greater. However, notwithstanding the costs, it appears that literature searches that rely on only one or the other database will inevitably miss pertinent information.

    1997-10-01

    Over 100 commercial providers with mixed-waste treatability capabilities exist in the US. The maturity level of these technologies varies from a bench scale to a pilot or a commercial scale. The techniques include deactivation, chemical oxidation, recovery of metals, stabilization, vitrification, incineration, biodegradation, and chemical extraction. This report focuses on the use of resins to remove actinides and heavy metals from aqueous waste streams. Only the literature that described resins with high removing efficiency are presented here. The majority of the literature reviewed are proceedings and national or international reports ordered through the Berkeley Lab Library. Some of the reports that the authors requested have not yet arrived. Only a few papers were found in the open literature (journals or magazines). Although this report does not include all existing references, it provides an accurate assessment of efficient resins to be considered for waste minimization procedures. 70 refs.

    Evans, K; McGrath, J; Milns, R

    2003-05-01

    The aim of this study was to systematically examine ancient Roman and Greek texts to identify descriptions of schizophrenia and related disorders. Material from Greek and Roman literature dating from the 5th Century BC to the beginning of the 2nd Century AD was systematically reviewed for symptoms of mental illness. DSM IV criteria were applied in order to identify material related to schizophrenia and related disorders. The general public had an awareness of psychotic disorders, because the symptoms were described in works of fiction and in historical accounts of malingering. There were isolated instances of text related to psychotic symptoms in the residents of ancient Rome and Greece, but no written material describing a condition that would meet modern diagnostic criteria for schizophrenia. In contrast to many other psychiatric disorders that are represented in ancient Greek and Roman literature, there were no descriptions of individuals with schizophrenia in the material assessed in this review.

  15. Ancient Glass: A Literature Search and its Role in Waste Management

    Energy Technology Data Exchange (ETDEWEB)

    Strachan, Denis M.; Pierce, Eric M.

    2010-07-01

    When developing a performance assessment model for the long-term disposal of immobilized low-activity waste (ILAW) glass, it is desirable to determine the durability of glass forms over very long periods of time. However, testing is limited to short time spans, so experiments are performed under conditions that accelerate the key geochemical processes that control weathering. Verification that models currently being used can reliably calculate the long term behavior ILAW glass is a key component of the overall PA strategy. Therefore, Pacific Northwest National Laboratory was contracted by Washington River Protection Solutions, LLC to evaluate alternative strategies that can be used for PA source term model validation. One viable alternative strategy is the use of independent experimental data from archaeological studies of ancient or natural glass contained in the literature. These results represent a potential independent experiment that date back to approximately 3600 years ago or 1600 before the current era (bce) in the case of ancient glass and 106 years or older in the case of natural glass. The results of this literature review suggest that additional experimental data may be needed before the result from archaeological studies can be used as a tool for model validation of glass weathering and more specifically disposal facility performance. This is largely because none of the existing data set contains all of the information required to conduct PA source term calculations. For example, in many cases the sediments surrounding the glass was not collected and analyzed; therefore having the data required to compare computer simulations of concentration flux is not possible. This type of information is important to understanding the element release profile from the glass to the surrounding environment and provides a metric that can be used to calibrate source term models. Although useful, the available literature sources do not contain the required information

    Héctor Gómez Dantés

    Full Text Available This systematic literature review describes the epidemiology of dengue disease in Mexico (2000-2011. The annual number of uncomplicated dengue cases reported increased from 1,714 in 2000 to 15,424 in 2011 (incidence rates of 1.72 and 14.12 per 100,000 population, respectively. Peaks were observed in 2002, 2007, and 2009. Coastal states were most affected by dengue disease. The age distribution pattern showed an increasing number of cases during childhood, a peak at 10-20 years, and a gradual decline during adulthood. All four dengue virus serotypes were detected. Although national surveillance is in place, there are knowledge gaps relating to asymptomatic cases, primary/secondary infections, and seroprevalence rates of infection in all age strata. Under-reporting of the clinical spectrum of the disease is also problematic. Dengue disease remains a serious public health problem in Mexico.

    Full Text Available Joining of fixed appliance components has several applications in orthodontics. Joining attachments to archwires allows the clinician to transfer the point of force application to a location that is more advantageous from a biomechanical standpoint. Although several methods of joining attachments have been proposed, resistance spot welding and soldering have been the most commonly used procedures. Despite its common use, the literature regarding spot welding has been scarce and the technique improperly applied. The aim of this article is to describe the theory behind the use of electric spot welders and achieving an optimum weld joint. Recommendations have been made for the correct application of the parameters involved in electric resistance spot welding so that a clinically useful weld joint can be obtained.

    2011-07-01

    Full Text Available Abstract Background Two of the key steps in evidence based medicine (EBM are being able to construct a clinical question and effectively search the literature to source relevant information. No evidence currently exists that informs whether such skills should be taught to medical students during their pre-clinical years, or delivered to include both the pre-clinical and clinical years of study. This is an important component of curriculum design as the level of clinical maturity of students can affect their perception of the importance and uptake of EBM principles in practice. Methods/Design A randomised controlled trial will be conducted to identify the effectiveness of delivering a formal workshop in EBM literature searching skills to third year medical students entering their clinical years of study. The primary outcome of EBM competency in literature searching skills will be evaluated using the Fresno tool. Discussion This trial will provide novel information on the effectiveness of delivering a formal education workshop in evidence based medicine literature searching skills during the clinical years of study. The result of this study will also identify the impact of teaching EBM literature searching skills to medical students during the clinical years of study.

  1. Searching the seat of the soul in Ancient Greek and Byzantine medical literature.

    2010-12-01

    The objective of this paper was to examine the ancient and medieval concepts about the seat of the mental functions, as exposed in Greek texts from Antiquity to Byzantine times. The review of the philosophical and medical literature from the original ancient Greek language from the Homeric epics to the Holy Fathers of Christianity, as the problem of the seat of the soul remained without a certain answer through the centuries. Primitive concepts attributed great significance to the soul and dictated cannibal behaviours for the possession and eating of the defeated enemy's heart. Mental functions, such as thinking, feeling and mainly those related to affective manifestations, were attributed to the heart and to some other internal organs (liver, diaphragm) from the times of Greek mythology. Philosophy and empirical medicine had underestimated the brain probably because it is a 'silent' organ, contrary to the palpitating heart, with its obvious participations in the emotional reactions. The role of the brain as the mental organ and the seat of emotions has been gradually recognized. The permanent question of the seat of the soul had been for many centuries a critical dispute and the contribution of Greek philosophical and medical thought was decisive for the contemporary transformation of the whole concept.

    (1) To find a universal strategy for the identification of specific demands of a job or task, focusing on occupations in which there may be an increased risk for health complaints owing to these specific demands. (2) To select reliable and valid tests concerning lifting, pushing, and pulling, which consider the relation between occupational work demands and the assessment of the maximally acceptable load on an individual level. Literature search was performed using Medline (1988 to May 2001), Embase (1966 to May 2001), and NIOSHTIC (1971-98). No universal strategy was found for the definition of specific occupational demands. Therefore a "three step strategy" was formulated for defining specific occupational demands in a job or a task in order to prevent health complaints on an individual level. Many tests were found in the literature concerning lifting, but only a few concerning pushing and pulling. None of the tests concerning pushing, pulling, or lifting considered the relation between work demands and the assessment of the maximally acceptable load on an individual level. Furthermore, none of the tests met the criteria of reliability and prognostic value for musculoskeletal complaints completely. Only for the prognostic value of relative strength capacity tests concerning pushing pulling and lifting, did there appear to be limited proof for the development of musculoskeletal complaints. In general, for the prevention of work related health complaints, it can be suggested that more attention should be paid to: (1) the definition of specific occupational demands; (2) the assessment of specific occupational demands; and (3) the quality of tests for specific occupational demands.

    The Astrophysics Data System (ADS) provides access to the astronomical literature through the World Wide Web. It is a NASA funded project and access to all the ADS services is free to everybody world-wide. The ADS Abstract Service allows searching of four databases with abstracts in Astronomy, Instrumentation, Physics/Geophysics, and the astro-ph Preprints with a total of almost 2.5 million references in the databases. The system also provides access to reference and citation information, links to on-line data and other on-line information, and to on-line electronic journals. In addition the ADS has 1.9 million scanned article pages from about 250,000 articles, dating back as far as 1829. The ADS Article Service contains the full articles for most of the astronomical literature back to volume 1. It contains the scanned pages of all the major journals in Astronomy (Astrophysical Journal, Astronomical Journal, Astronomy & Astrophysics, Monthly Notices of the Royal Astronomical Society, and Solar Physics), as well as most smaller journals back to volume 1 for each of these journals. One important aspect of the ADS is the system of links to other data systems. We have currently more than 6 million links to other on-line resources, including on-line data and on-line journal articles. There are currently more than 10,000 regular users (more than 10 queries/month). The total number of users is greater than 50,000 per month. They issue almost 1 million queries per month and receive more than 30 million records and 1.2 million scanned article pages per month. The ADS is accessed from almost 100 countries. Approximately 1/3 of the use is from the USA, 1/3 from Europe, and 1/3 from the rest of the world. Usage depends primarily on the number of astronomers in each country, but also on the Gross Domestic Product of that country. In order to improve access from different parts of the world, we maintain 9 mirror sites of the ADS in Brazil, Chile, China, England, France, Germany

    Full Text Available Background: ‘Hard-to-reach’ is a term used to describe those sub-groups of the populationthat may be difficult to reach or involve in research or public health programmes. Applicationof a single term to call these sub-sections of populations implies a homogeneity within distinctgroups, which does not necessarily exist. Different sampling techniques were introduced sofar to recruit hard-to-reach populations. In this article, we have reviewed a range of approachesthat have been used to widen participation in studies.Methods: We performed a Pubmed and Google search for relevant English language articlesusing the keywords and phrases: (hard-to-reach AND population* OR sampl*, (hidden ANDpopulation* OR sample* and (“hard to reach” AND population* OR sample* and a consultationof the retrieved articles’ bibliographies to extract empirical evidence from publicationsthat discussed or examined the use of sampling techniques to recruit hidden or hard-to-reachpopulations in health studies.Results: Reviewing the literature has identified a range of techniques to recruit hard-to-reachpopulations, including snowball sampling, respondent-driven sampling (RDS, indigenousfield worker sampling (IFWS, facility-based sampling (FBS, targeted sampling (TS, timelocation(space sampling (TLS, conventional cluster sampling (CCS and capture re-capturesampling (CR.Conclusion: The degree of compliance with a study by a certain ‘hard-to-reach’ group dependson the characteristics of that group, recruitment technique used and the subject of interest.Irrespective of potential advantages or limitations of the recruitment techniques reviewed,their successful use depends mainly upon our knowledge about specific characteristics of thetarget populations. Thus in line with attempts to expand the current boundaries of our knowledgeabout recruitment techniques in health studies and their applications in varying situations,we should also focus on possibly all contributing

    2017-09-01

    Rising demand for emergency and urgent care services is well documented, as are the consequences, for example, emergency department (ED) crowding, increased costs, pressure on services, and waiting times. Multiple factors have been suggested to explain why demand is increasing, including an aging population, rising number of people with multiple chronic conditions, and behavioral changes relating to how people choose to access health services. The aim of this systematic mapping review was to bring together published research from urgent and emergency care settings to identify drivers that underpin patient decisions to access urgent and emergency care. Systematic searches were conducted across Medline (via Ovid SP), EMBASE (via Ovid), The Cochrane Library (via Wiley Online Library), Web of Science (via the Web of Knowledge), and the Cumulative Index to Nursing and Allied Health Literature (CINAHL; via EBSCOhost). Peer-reviewed studies written in English that reported reasons for accessing or choosing emergency or urgent care services and were published between 1995 and 2016 were included. Data were extracted and reasons for choosing emergency and urgent care were identified and mapped. Thematic analysis was used to identify themes and findings were reported qualitatively using framework-based narrative synthesis. Thirty-eight studies were identified that met the inclusion criteria. Most studies were set in the United Kingdom (39.4%) or the United States (34.2%) and reported results relating to ED (68.4%). Thirty-nine percent of studies utilized qualitative or mixed research designs. Our thematic analysis identified six broad themes that summarized reasons why patients chose to access ED or urgent care. These were access to and confidence in primary care; perceived urgency, anxiety, and the value of reassurance from emergency-based services; views of family, friends, or healthcare professionals; convenience (location, not having to make appointment, and opening hours

Pain scales are a commonly reported outcome measure. Virtual reality is persuasive for all children in distress during medical procedures, because it is a nonaddictive, novel, and inexpensive form of distraction which can be applied repeatedly with good effect. We intend to use virtual reality in South Africa for the many children hospitalized with severe burns from mechanisms rarely seen in the Western world (paraffin/kerosene stoves exploding, electrical fires, shack/township fires, boiling liquid spills. Many severely burnt children are indigenous South Africans who did not speak English, and whose illiteracy levels, cultures, family dynamics, and experiences of pain potentially invalidate the use of conventional pain scales as outcome measures. The purpose of this study was to identify objective measures with sound psychometric properties and strong clinical utility, to assess distress during burns dressing changes in hospitalized indigenous South African children. Choice of measures was constrained by the burns dressing change environment, the ethics of doing no harm whilst measuring distress in vulnerable children, and of capturing valid measures of distress over the entire burns dressing change procedure.Methods: We conducted two targeted systematic reviews of the literature. All major library databases were searched, and measures with strong psychometric properties and sound clinical utility were sought.Results: Seven potentially useful measures were identified, ie

    2013-06-01

    Extensive research has identified stereotypic behavioral and biological abnormalities in post-traumatic stress disorder (PTSD), such as heightened autonomic activity, an exaggerated startle response, reduced basal cortisol levels and cognitive impairments. We have reviewed primary research in this area, noting that factors involved in the susceptibility and expression of PTSD symptoms are more complex and heterogeneous than is commonly stated, with extensive findings which are inconsistent with the stereotypic behavioral and biological profile of the PTSD patient. A thorough assessment of the literature indicates that interactions among myriad susceptibility factors, including social support, early life stress, sex, age, peri- and post-traumatic dissociation, cognitive appraisal of trauma, neuroendocrine abnormalities and gene polymorphisms, in conjunction with the inconsistent expression of the disorder across studies, confounds attempts to characterize PTSD as a monolithic disorder. Overall, our assessment of the literature addresses the great challenge in developing a behavioral and biomarker-based diagnosis of PTSD. Published by Elsevier Ltd.

    Individual summaries and pertinent commentaries on each of the groups of references into which the literature on carbon dioxide for the recovery of crude oil has been classified are presented in this report. The major classifications are: physical models, laboratory studies, field tests, modelling, patents, and miscellaneous. A special summary that reviews and comments on field operations, fluid handling, and corrosion problems is also included. User's guide and subject categories for the CO/sub 2/ literature survey are given, followed by abstracts of the citations. It is concluded from this survey that the most significant deficiency in research on carbon dioxide flooding for the recovery of crude oil is the paucity of well controlled and interpreted field tests.

    Background Current recommendations for the management of axial spondyloarthritis (SpA) and psoriatic arthritis are to monitor disease activity and adjust therapy accordingly. However, treatment targets and timeframes of change have not been defined. An international expert panel has been convened to develop ‘treat-to-target’ recommendations, based on published evidence and expert opinion. Objective To review evidence on targeted treatment for axial and peripheral SpA, as well as for psoriatic skin disease. Methods We performed a systematic literature search covering Medline, Embase and Cochrane, conference abstracts and studies in http://www.clinicaltrials.gov. Results Randomised comparisons of targeted versus routine treatment are lacking. Some studies implemented treatment targets before escalating therapy: in ankylosing spondylitis, most trials used a decrease in Bath Ankylosing Spondylitis Disease Activity Index; in psoriatic arthritis, protocols primarily considered a reduction in swollen and tender joints; in psoriasis, the Modified Psoriasis Severity Score and the Psoriasis Area and Severity Index were used. Complementary evidence correlating these factors with function and radiographic damage at follow-up is sparse and equivocal. Conclusions There is a need for randomised trials that investigate the value of treat-to-target recommendations in SpA and psoriasis. Several trials have used thresholds of disease activity measures to guide treatment decisions. However, evidence on the effect of these data on long-term outcome is scarce. The search data informed the expert committee regarding the formulation of recommendations and a research agenda. PMID:23740234

    Baru, C.; Lin, K.

    2009-04-01

    The Geosciences Network project (www.geongrid.org) has been developing cyberinfrastructure for data sharing in the Earth Science community based on a service-oriented architecture. The project defines a standard "software stack", which includes a standardized set of software modules and corresponding service interfaces. The system employs Grid certificates for distributed user authentication. The GEON Portal provides online access to these services via a set of portlets. This service-oriented approach has enabled the GEON network to easily expand to new sites and deploy the same infrastructure in new projects. To facilitate interoperation with other distributed geoinformatics environments, service standards are being defined and implemented for catalog services and federated search across distributed catalogs. The need arises because there may be multiple metadata catalogs in a distributed system, for example, for each institution, agency, geographic region, and/or country. Ideally, a geoinformatics user should be able to search across all such catalogs by making a single search request. In this paper, we describe our implementation for such a search capability across federated metadata catalogs in the GEON service-oriented architecture. The GEON catalog can be searched using spatial, temporal, and other metadata-based search criteria. The search can be invoked as a Web service and, thus, can be imbedded in any software application. The need for federated catalogs in GEON arises because, (i) GEON collaborators at the University of Hyderabad, India have deployed their own catalog, as part of the iGEON-India effort, to register information about local resources for broader access across the network, (ii) GEON collaborators in the GEO Grid (Global Earth Observations Grid) project at AIST, Japan have implemented a catalog for their ASTER data products, and (iii) we have recently deployed a search service to access all data products from the EarthScope project in the US

    External content sources such as MEDLINE(®), National Institutes of Health (NIH) grants and conference websites provide access to the latest breaking biomedical information, which can inform pharmaceutical and biotechnology company pipeline decisions. The value of the sites for industry, however, is limited by the use of the public internet, the limited synonyms, the rarity of batch searching capability and the disconnected nature of the sites. Fortunately, many sites now offer their content for download and we have developed an automated internal workflow that uses text mining and tailored ontologies for programmatic search and knowledge extraction. We believe such an efficient and secure approach provides a competitive advantage to companies needing access to the latest information for a range of use cases and complements manually curated commercial sources.

    Full Text Available : Las encuestas llevadas a cabo durante el régimen militar pusieron de manifiesto que las evaluaciones de diferentes políticas públicas correlacionan muy poco entre sí, son particularmente bajas entre analfabetos y encuestados con niveles educativos bajos, y no constituyen buenos predictores de la intención de voto y de las preferencias partidistas. Sin embargo, datos procedentes de una amplia encuesta domiciliar preelectoral en el Distrito Federal, con una muestra aleatoria estratificada, contradicen estos resultados; existe correlación entre evaluaciones de distintas políticas públicas, la magnitud de las correlaciones entre evaluaciones de políticas públicas no sigue un patrón de relación con los niveles educativos y constituyen una excelente predictor de las preferencias de voto para las elecciones a gobernador. Las disparidades que arrojan estos resultados pudieran ser resultado de cambios reales en la población a lo largo de los últimos quince años, a especificidades del Distrito Federal (niveles de renta per cápita más altos y uno de los más altos niveles educativos del país, a una elección en la que el candidato de la gobernación saliente compite contra un exgobernador, al énfasis de la campaña del gobernador saliente, a características del régimen militar o a una combinación de todas ellas. Cualquiera que sea la explicación, las elecciones de 1998 mostraron la existencia de una racionalidad que conecta la intención de voto con la evaluación de políticas públicas. No obstante, este vínculo pudiera ser específico y no generalizable a otros niveles electorales ni a preferencias partidistas.Surveys carried out during the military regime have shown that the evaluation of different public policies have low correlations with each other, are particularly low among illiterates and poorly educated respondents and were poor predictors of voting intention and party preferences.

    2016-03-01

    Full Text Available Various options for medical treatment of children with compression fractures of the thoracic and lumbar spine include unloading of damaged segments by simultaneous or gradual reclination (e.g., functional traction and reclination of the spine; measures aimed at building and strengthening the muscular “corset” of the back; and the use of orthotic devices of various designs (e.g., fixating-discharging, fixating-correcting corsets, orthoses on a modular basis. Questions regarding the early and late use of orthotics in patients with compression fractures of the vertebral bodies are discussed. Literature analysis, considering different methods used in the treatment of these patients in terms of their effectiveness to restore the height and shape of the damaged spinal segment revealed the absence of a differentiated approach for choosing treatment and selection criteria for orthopedic management.

    In Mali, the empirical knowledge on plant medicine is held by traditional practioners. Scientific studies have been carried on some plants and they have confirmed their local uses, but few data are available on the toxicity of Malian medicinal plants. In the present work, we record the toxic plants used as medicines in the Bamako district, Mali, with the aim to evaluate the knowledge of traditional healers and herbalists on the toxicity of the plant used. A survey was carried out on the market places in the Bamako district and 106 healers and herbalists were interviewed. A survey of the scientific literature was conducted to verify or sustain the claimed toxicological data. Nineteen plants are arranged according to their frequency of quotation based on the questionnaire. The information includes the botanical name, literature survey on the pharmacology of the plants, the healers' knowledge on plant toxicity and its prevention by some of the healers.

    Motivation is suggested as an important factor in pediatric motor rehabilitation. Therefore, we reviewed the existing evidence of (motivational) motor rehabilitation paradigms, and how motivation influences rehabilitation outcome using self-determination theory as conceptual framework. PubMed and Web-of-Science databases were systematically searched until June 2015. Data were independently extracted and critiqued for quality by three authors. Studies reporting motivational aspects were included. Most studies examined new technology (e.g., virtual reality [VR]). Out of 479 records, three RCT, six case-control, and six non-comparative studies were included with mixed quality. Motivation was rarely reported. Training individualization to the child's capabilities with more variety seemed promising to increase motivation. Motivation increased when the exercises seemed helpful for daily activities. Motivation in pediatric rehabilitation should be comprehensively assessed within a theoretical framework as there are indications that motivated children have better rehabilitation outcomes, depending on the aspect of motivation.

    Biomarkers allowing the identification of individuals with an above average vulnerability or resilience for posttraumatic stress disorder (PTSD) would especially serve populations at high risk for trauma exposure like firefighters, police officers and combat soldiers. Aiming to identify the most promising putative PTSD vulnerability markers, we conducted the first systematic review on potential imaging and non-genetic molecular markers for PTSD risk and resilience. Following the PRISMA guidelines, we systematically screened the PubMed database for prospective longitudinal clinical studies and twin studies reporting on pre-trauma and post-trauma PTSD risk and resilience biomarkers. Using 25 different combinations of search terms, we retrieved 8151 articles of which we finally included and evaluated 9 imaging and 27 molecular studies. In addition, we briefly illustrate the design of the ongoing prospective German Armed Forces (Bundeswehr) PTSD biomarker study (Bw-BioPTSD) which not only aims to validate these previous findings but also to identify novel and clinically applicable molecular, psychological and imaging risk, resilience and disease markers for deployment-related psychopathology in a cohort of German soldiers who served in Afghanistan.

  15. Worldwide trends in fishing interest indicated by Internet search volume

    Science.gov (United States)

    Wilde, G.R.; Pope, K.L.

    2013-01-01

    There is a growing body of literature that shows internet search volume on a topic, such as fishing, is a viable measure of salience. Herein, internet search volume for 'fishing' and 'angling' is used as a measure of public interest in fishing, in particular, recreational fishing. An online tool, Google Insights for Search, which allows one to study internet search terms and their volume since 2004, is used to examine trends in interest in fishing for 50 countries. Trends in normalised fishing search volume, during 2004 through 2011, varied from a 72.6% decrease (Russian Federation) to a 133.7% increase (Hungary). Normalised fishing search volume declined in 40 (80%) of the countries studied. The decline has been relatively large in English-speaking countries, but also has been large in Central and South American, and European countries. Analyses of search queries provide a low-cost means of gaining insight into angler interests and, possibly, behaviour in countries around the world.

    Full Text Available Purpose of this study is to elaborate the political issues and challenges faces by the federation of Pakistan during and after the Gen. Pervez Musharraf government. In this paper effort is made to discuss those issues on the biases of which politics of federalism started in the country. Pinching problems that caused disintegration to Pakistan are also discussed. Those issues are also discussed in details which are a constant threat to the “new federation of Pakistan”. Authors also focus on the 2008 elections and its consequences on Pakistan politics. All the results of this research are proved via review of the previous literature. Researchers have proved that as Pakistan has a diversified culture so federalism is best suited for its political structure. Researchers have also discussed few suggestive solutions for better bureaucracy.

  2. Fiscal Federalism

    Directory of Open Access Journals (Sweden)

    Tatiana Mosteanu

    2007-06-01

    Full Text Available The central budget of a country collects only a fraction of the total fiscal revenues and executes only o fraction of the national public expenditures, the rest of the revenues and expenditures becoming the responsability of subnational governments. The economist Charles Tiebout developed a theoretical model which although makes an imperfect description of the reality, shows that people’s mobility is being influenced by tax rates and the amount of state/local expenditures. Thus, he suggests that the degree of responsibility that can be appointed to the local budgets should subscribe to the tax – benefits ratio, the extend of the positive externalities and the scale economies of public goods. Also, the issue of revenues distribution among communities is being raised, being identified three kinds of grants used by the public authorities: matching grants, block grants and conditional block grants. In the concept of fiscal federalism there can be found a limited analogy between national public finance theory and international public finance theory, with the international taxation as the pivotal element.

  6. Search features of digital libraries

    Directory of Open Access Journals (Sweden)

    Alastair G. Smith

    2000-01-01

    Full Text Available Traditional on-line search services such as Dialog, DataStar and Lexis provide a wide range of search features (boolean and proximity operators, truncation, etc. This paper discusses the use of these features for effective searching, and argues that these features are required, regardless of advances in search engine technology. The literature on on-line searching is reviewed, identifying features that searchers find desirable for effective searching. A selective survey of current digital libraries available on the Web was undertaken, identifying which search features are present. The survey indicates that current digital libraries do not implement a wide range of search features. For instance: under half of the examples included controlled vocabulary, under half had proximity searching, only one enabled browsing of term indexes, and none of the digital libraries enable searchers to refine an initial search. Suggestions are made for enhancing the search effectiveness of digital libraries, for instance by: providing a full range of search operators, enabling browsing of search terms, enhancement of records with controlled vocabulary, enabling the refining of initial searches, etc.

    2015-01-01

    As the volume of electronically available information grows, relevant items become harder to find. This work presents an approach to personalizing search results in scientific publication databases. This work focuses on re-ranking search results from existing search engines like Solr or ElasticSearch. This work also includes the development of Obelix, a new recommendation system used to re-rank search results. The project was proposed and performed at CERN, using the scientific publications available on the CERN Document Server (CDS). This work experiments with re-ranking using offline and online evaluation of users and documents in CDS. The experiments conclude that the personalized search result outperform both latest first and word similarity in terms of click position in the search result for global search in CDS.

  19. Search Combinators

    CERN Document Server

    Schrijvers, Tom; Wuille, Pieter; Samulowitz, Horst; Stuckey, Peter J

    2012-01-01

    The ability to model search in a constraint solver can be an essential asset for solving combinatorial problems. However, existing infrastructure for defining search heuristics is often inadequate. Either modeling capabilities are extremely limited or users are faced with a general-purpose programming language whose features are not tailored towards writing search heuristics. As a result, major improvements in performance may remain unexplored. This article introduces search combinators, a lightweight and solver-independent method that bridges the gap between a conceptually simple modeling language for search (high-level, functional and naturally compositional) and an efficient implementation (low-level, imperative and highly non-modular). By allowing the user to define application-tailored search strategies from a small set of primitives, search combinators effectively provide a rich domain-specific language (DSL) for modeling search to the user. Remarkably, this DSL comes at a low implementation cost to the...

    2015-12-01

    At AGU 2014, NASA EOSDIS demonstrated a case-study of an OpenSearch framework for Earth science data discovery. That framework leverages the IDN and CWIC OpenSearch API implementations to provide seamless discovery of data through the 'two-step' discovery process as outlined by the Federation for Earth Sciences (ESIP) OpenSearch Best Practices. But how would an Earth Scientist leverage this framework and what are the benefits? Using a client that understands the OpenSearch specification and, for further clarity, the various best practices and extensions, a scientist can discovery a plethora of data not normally accessible either by traditional methods (NASA Earth Data Search, Reverb, etc) or direct methods (going to the source of the data) We will demonstrate, via the CWICSmart web client, how an earth scientist can access regional data on a regional phenomena in a uniform and aggregated manner. We will demonstrate how an earth scientist can 'globalize' their discovery. You want to find local data on 'sea surface temperature of the Indian Ocean'? We can help you with that. 'European meteorological data'? Yes. 'Brazilian rainforest satellite imagery'? That too. CWIC allows you to get earth science data in a uniform fashion from a large number of disparate, world-wide agencies. This is what we mean by Global OpenSearch.

    Federal efforts and local initiatives to increase adoption and use of electronic health records (EHRs) continue, particularly since the enactment of the Health Information Technology for Economic and Clinical Health (HITECH) Act. Roughly one in four hospitals not adopted even a basic EHR system. A review of the barriers may help in understanding the factors deterring certain healthcare organizations from implementation. We wanted to assemble an updated and comprehensive list of adoption barriers of EHR systems in the United States. Authors searched CINAHL, MEDLINE, and Google Scholar, and accepted only articles relevant to our primary objective. Reviewers independently assessed the works highlighted by our search and selected several for review. Through multiple consensus meetings, authors tapered articles to a final selection most germane to the topic (n = 27). Each article was thoroughly examined by multiple authors in order to achieve greater validity. Authors identified 39 barriers to EHR adoption within the literature selected for the review. These barriers appeared 125 times in the literature; the most frequently mentioned barriers were regarding cost, technical concerns, technical support, and resistance to change. Despite federal and local incentives, the initial cost of adopting an EHR is a common existing barrier. The other most commonly mentioned barriers include technical support, technical concerns, and maintenance/ongoing costs. Policy makers should consider incentives that continue to reduce implementation cost, possibly aimed more directly at organizations that are known to have lower adoption rates, such as small hospitals in rural areas.

  3. Telemedicine in the Federated States of Micronesia.

    Telemedicine (other than costly long distance telephone and facsimile messages) in the Federated States of Micronesia (FSM) started approximately 4 years ago with the establishment of Internet access in the State of Yap. A local access, for medical use only, via already established trunk lines maintained by Continental Airlines was established. It provided a connection to CompuServe at a baud rate of 300 bps. FSM TeleCom provided this free service. While this connection was slow, it allowed medical staff at Yap State Hospital to send and receive text based e-mail regarding patient management. By its use interest was generated in both medical and non-medical individuals to develop a commercial full scale Internet service. In March 1996, TeleCom became a full scale commercial Internet Service Provider in Yap. Rates were reasonable and the CompuServe access was phased out. The full scale internet allowed medical personnel to engage in telemedicine activities, including email; email attachments; the search and retrieval of medical literature; transmission to medical specialists of X-rays, ECG's and other images; and real-time teleconferencing over the Internet with both audio and video. In addition, to the improvement of medical care, this allowed for greater efficiency in arranging referral of patients for medical treatment outside of the FSM.

  4. Findability of Federal Research Data

    Findability of Federal Research Data Although many of the federal agencies have been providing access to scientific research data for years if not decades, the findability of the data has been quite lacking. Many discipline-wide efforts have been made in the big science communities, such as PDS for planetary science and the VOs in night time astronomy and heliophysics, but there is a lack of single entry point for someone looking for data. The science.gov website contains links to many of these big-science search systems, but doesn't differentiate between links to science quality data and websites or browse products, making it more difficult to search specifically for data. The data.gov website is a useful repository for PIs of small science data to stash their data, particularly as it allows for interested parties to interact with tabular data. Unfortunately, as each group thinks of their data differently, much of what's now in the system is a mess; collections of data being tracked as individual records with no relationships between them. Big science projects also get tracked as single records, potentially with only a single record for missions with multiple instruments and significantly different data series. We present recommendations on how to improve the findability of federal research data on data.gov, based on years of working on the Virtual Solar Observatory and withing the science informatics community.

    We live in an information age that requires us, more than ever, to represent, access, and use information. Over the last several decades, we have developed a modern science and technology for information retrieval, relentlessly pursuing the vision of a "memex" that Vannevar Bush proposed in his seminal article, "As We May Think." Faceted search plays a key role in this program. Faceted search addresses weaknesses of conventional search approaches and has emerged as a foundation for interactive information retrieval. User studies demonstrate that faceted search provides more

    Full Text Available Open search systems present a free and less restricted alternative to commercial search services. This paper explores the space of open search technology looking in particular at the issue of interoperability. A description of current protocols and formats for engineering open search applications is presented. The suitability of these technologies and issues around their adoption and operation are discussed. This open search approach is especially proving a fitting choice in applications involving the harvesting of resources and information integration. Principal among the technological solutions are OpenSearch and SRU. OpenSearch and SRU implement a federated model to enable existing and new search engines and search clients communicate. Applications and instances where Opensearch and SRU can be combined are presented. Other relevant technologies such as OpenURL, Apache Solr, and OAI-PMH are also discussed. The deployment of these freely licensed open standards in digital library applications is now a genuine alternative to commercial or proprietary systems.

    2015-03-18

    This article examines how to synthesise and critique research literature. To place the process of synthesising the research literature into context, the article explores the critiquing process by breaking it down into seven sequential steps. The article explains how and why these steps need to be kept in mind if a robust comprehensive literature search and analysis are to be achieved. The article outlines how to engage in the critiquing process and explains how the literature review needs to be assembled to generate a logical and reasoned debate to examine a topic of interest or research in more detail.

    Evidence-based nursing practice requires the use of effective search strategies to locate relevant resources to guide practice change. Continuing education and staff development professionals can assist nurses to conduct effective literature searches. This article provides suggestions for strategies to aid in identifying search terms. Strategies also are recommended for refining searches by using controlled vocabulary, truncation, Boolean operators, PICOT (Population/Patient Problem, Intervention, Comparison, Outcome, Time) searching, and search limits. Suggestions for methods of managing resources also are identified. Using these approaches will assist in more effective literature searches and may help evidence-based practice decisions.

    Full Text Available Abstract: Two majors linguistics and literature in the schools of letters both in the state and private universities throughout Indonesia are commonly separated sharply. Courses of literature in the Department of Linguistics are offered minimally, such that the students of linguistics are not given a conducive atmosphere to express their literary appreciation. Likewise, courses of linguistics in the Department of Literature are very restricted, so that the students of literature are unable to analyze literary works from the points of linguistic view. This paper tries to bridge linguistics and literature. The attempt to bridge linguistics and literature is based on three postulates: (I literature consists of linguistic objects designed with an artistic end, (2 linguistic objects are formal objects, and (3 a formal account of linguistic object designed with an artistic end approximates a formal account of that artistic design. Two major directions in the approaches and emphases will be presented in the paper exogenous and endogenous. Exogenous approach tries to search for adequate description of (1 poetic language as contrasted with ordinary language, (2 language of a particular author contrasted with that of other authors, and (3 a particular literary work contrasted with other works of the same author. This part touches upon three areas of exogenous approach isolation, description, and characterization. Endogenous, on the hand, is based upon an assumption that a writer exhibits, probably without realizing it, certain systematic preferences for particular aspects of linguistic patterns. Planning a bridge between linguistics and literature is by no means without problems. Therefore, this paper also presents some possible solutions.

    The Standard Model of particle physics encompasses three of the four known fundamental forces of nature, and has remarkably withstood all of the experimental tests of its predictions, a fact solidified by the discovery, in 2012, of the Higgs boson. However, it cannot be the complete picture. Many measurements have been made that hint at physics beyond the Standard Model, and the main task of the high- energy experimental physics community is to conduct searches for new physics in as many di↵erent places and regimes as possible. I present three searches for new phenomena in three di↵erent high-energy collider experiments, namely, a search for events with at least three photons in the final state, which is sensitive to an exotic decay of a Higgs boson into four photons via intermediate pseudoscalar particles, a, with ATLAS, at the Large Hadron Collider; a search for a dark photon, also known as an A0 , with APEX, at Thomas Je↵erson National Accelerator Facility; and a search for a Higgs decaying into four...

    The innovation performance of modern firms is increasingly determined by their ability to search and absorb external knowledge. However, after a certain threshold firms "oversearch" their environment and innovation performance declines. In this paper, we argue that prior literature has largely...... ignored the institutional context that provides or denies access to external knowledge at the country level. Combining institutional and knowledge search theory, we suggest that the market orientation of the institutional environment and the magnitude of institutional change influence when firms begin...... to experience the negative performance effects of oversearch. Based on a comprehensive sample of almost 8,000 firms from ten European countries, we find that institutions matter considerably for firms' search activity. Higher market orientation of institutions increases the effectiveness of firms' search...

    Individuals and groups who write systematic reviews and meta-analyses in evidence-based medicine regularly carry out literature searches across multiple search engines linked to different bibliographic databases, and thus have an urgent need for a suitable metasearch engine to save time spent on repeated searches and to remove duplicate publications from initial consideration. Unlike general users who generally carry out searches to find a few highly relevant (or highly recent) articles, systematic reviewers seek to obtain a comprehensive set of articles on a given topic, satisfying specific criteria. This creates special requirements and challenges for metasearch engine design and implementation. We created a federated search tool that is connected to five databases: PubMed, EMBASE, CINAHL, PsycINFO, and the Cochrane Central Register of Controlled Trials. Retrieved bibliographic records were shown online; optionally, results could be de-duplicated and exported in both BibTex and XML format. The query interface was extensively modified in response to feedback from users within our team. Besides a general search track and one focused on human-related articles, we also added search tracks optimized to identify case reports and systematic reviews. Although users could modify preset search options, they were rarely if ever altered in practice. Up to several thousand retrieved records could be exported within a few minutes. De-duplication of records returned from multiple databases was carried out in a prioritized fashion that favored retaining citations returned from PubMed. Systematic reviewers are used to formulating complex queries using strategies and search tags that are specific for individual databases. Metta offers a different approach that may save substantial time but which requires modification of current search strategies and better indexing of randomized controlled trial articles. We envision Metta as one piece of a multi-tool pipeline that will assist

    Typical engineering methods utilized to calculate stresses on a roof structure involve simplifying assumptions that render a complex non-linear structure a simple and basic determinate beam. That is, instead of considering the composite action of the entire roof structure, the engineer evaluates only a single beam that is deemed conservatively to represent an affected rafter or top chord of a truss. This simplification based on assumptions of a complex problem is where significant conservatism can be introduced. Empirical data will be developed to evaluate this issue. Simple wood beams will be tested to failure. More complex and complete sections of roof structures that include composite action will also be tested to failure. The results can then be compared. An initial step in this process involves a literature review of any work that has been performed on roof structure composite action. The following section summarizes the literature review that was completed.

    Decades of innovations in combinatorial problem solving have produced better and more complex algorithms. These new methods are better since they can solve larger problems and address new application domains. They are also more complex which means that they are hard to reproduce and often harder to fine-tune to the peculiarities of a given problem. This last point has created a paradox where efficient tools are out of reach of practitioners. Autonomous search (AS) represents a new research field defined to precisely address the above challenge. Its major strength and originality consist in the

    Full Text Available Information retrieval (IR techniques become a challenge to researchers due to huge growth of digital and information retrieval. As a wide variety of Hindi Data and Literature is now available on web, we have developed information retrieval system for Hindi documents. This paper presents a new searching technique that has promising results in terms of F-measure. Historically, there have been two major approaches to IR - keyword based search and concept based search. We have introduced new relation inclusive search which performs searching of documents using case role relation, spatial relation and temporal relation of query terms and gives results better than previously used approaches. In this method we have used new indexing technique which stores information about relation between terms along with its position. We have compared four types of searching: Keyword Based search without Relation Inclusive, Keyword Based search with Relation Inclusive, Concept Based search without Relation Inclusive and Concept Based search with Relation Inclusive. Our proposed searching method gave significant improvement in terms of F-measure. For experiments we have used Hindi document corpus, Gyannidhi from C-DAC. This technique effectively improves search performance for documents in English as well.

    Reprocessing of UNF that has been out of the reactor for less than about 50 y requires the removal of 85Kr from the process off-gas streams. This is needed despite the relatively small amount of that isotope in the combined Xe and Kr inventory (Table 1). The decay of 85Kr to 85Rb presents challenges to the materials that will potentially be used to remove and store the Kr recovered from the off-gas. To address some of these problems, a thorough literature survey was completed, and the results of that analysis are summarized in this document.

  5. Developing a Comprehensive Search Strategy for Evidence Based Systematic Reviews

    Full Text Available Objective ‐ Within the health care field it becomes ever more critical to conduct systematic reviews of the research literature to guide programmatic activities, policy‐making decisions, and future research. Conducting systematic reviews requires a comprehensive search of behavioural, social, and policy research to identify relevant literature. As a result, the validity of the systematic review findings and recommendations is partly a function of the quality of the systematic search of the literature. Therefore, a carefully thought out and organized plan for developing and testing a comprehensive search strategy should be followed. This paper uses the HIV/AIDS prevention literature to provide a framework for developing, testing, and conducting a comprehensive search strategy looking beyond RCTs.Methods ‐ Comprehensive search strategies, including automated and manual search techniques, were developed, tested, and implemented to locate published and unpublished citations in order to build a database of HIV/AIDS and sexually transmitted diseases (STD literature. The search incorporated various automated and manual search methods to decrease the chance of missing pertinent information. The automated search was implemented in MEDLINE, EMBASE,PsycINFO, Sociological Abstracts and AIDSLINE. These searches utilized both index terms as well as keywords including truncation, proximity, and phrases. The manual search method includes physically examining journals (hand searching, reference list checks, and researching key authors.Results ‐ Using automated and manual search components, the search strategy retrieved 17,493 articles about prevention of HIV/AIDS and STDs for the years 1988‐2005. The automated search found 91%, and the manual search contributed 9% of the articles reporting on HIV/AIDS or STD interventions with behavioural/biologic outcomes. Among the citations located with automated searches, 48% were found in only one database (20

    2015-12-01

    Full Text Available Objective – Effective literature searching is of paramount importance in supporting evidence based practice, research, and policy. Missed references can have adverse effects on outcomes. This paper reports on the development and evaluation of an online learning resource, designed for librarians and other interested searchers, presenting an evidence based approach to enhancing and testing literature searches. Methods – We developed and evaluated the set of free online learning modules for librarians called Smart Searching, suggesting the use of techniques derived from search filter development undertaken by the CareSearch Palliative Care Knowledge Network and its associated project Flinders Filters. The searching module content has been informed by the processes and principles used in search filter development. The self-paced modules are intended to help librarians and other interested searchers test the effectiveness of their literature searches, provide evidence of search performance that can be used to improve searches, as well as to evaluate and promote searching expertise. Each module covers one of four techniques, or core principles, employed in search filter development: (1 collaboration with subject experts; (2 use of a reference sample set; (3 term identification through frequency analysis; and (4 iterative testing. Evaluation of the resource comprised ongoing monitoring of web analytics to determine factors such as numbers of users and geographic origin; a user survey conducted online elicited qualitative information about the usefulness of the resource. Results – The resource was launched in May 2014. Web analytics show over 6,000 unique users from 101 countries (at 9 August 2015. Responses to the survey (n=50 indicated that 80% would recommend the resource to a colleague. Conclusions – An evidence based approach to searching, derived from search filter development methodology, has been shown to have value as an online learning

  10. Is searching full text more effective than searching abstracts?

    2009-02-01

    Full Text Available Abstract Background With the growing availability of full-text articles online, scientists and other consumers of the life sciences literature now have the ability to go beyond searching bibliographic records (title, abstract, metadata to directly access full-text content. Motivated by this emerging trend, I posed the following question: is searching full text more effective than searching abstracts? This question is answered by comparing text retrieval algorithms on MEDLINE® abstracts, full-text articles, and spans (paragraphs within full-text articles using data from the TREC 2007 genomics track evaluation. Two retrieval models are examined: bm25 and the ranking algorithm implemented in the open-source Lucene search engine. Results Experiments show that treating an entire article as an indexing unit does not consistently yield higher effectiveness compared to abstract-only search. However, retrieval based on spans, or paragraphs-sized segments of full-text articles, consistently outperforms abstract-only search. Results suggest that highest overall effectiveness may be achieved by combining evidence from spans and full articles. Conclusion Users searching full text are more likely to find relevant articles than searching only abstracts. This finding affirms the value of full text collections for text retrieval and provides a starting point for future work in exploring algorithms that take advantage of rapidly-growing digital archives. Experimental results also highlight the need to develop distributed text retrieval algorithms, since full-text articles are significantly longer than abstracts and may require the computational resources of multiple machines in a cluster. The MapReduce programming model provides a convenient framework for organizing such computations.

  15. Studies on forensic nursing in Brazil: a systematic review of the literature.

    Science.gov (United States)

    Pereira de Paiva, M H; Pinheiro Lages, L; Cavalcanti de Medeiros, Z

    2017-06-01

    To identify and synthesize the national and international literature on forensic nursing in Brazil. Forensic nursing is a new specialty to the nursing practice in Brazil, being recognized by the Federal Nursing Council of Brazil in 2011. In 2016, the first forensic nursing specialization programme was authorized in the country. The implementation of forensic nursing specialty in Brazil marks new possibilities for the nursing practice, making it possible for nurses to develop additional skills to intervene in various situations under the Brazilian Unified Healthcare System. A systematic search of the literature was conducted using the keyword 'Forensic nursing' in combination with 'Brazil'. LILACS, MEDLINE, EMBASE, Scopus and Web of Science databases were searched. Studies were also retrieved from the grey literature. Once literature had been identified, a thematic analysis was undertaken in order to extract themes, which were: establishment of the forensic nursing specialty and its contributions to Brazil and its practical implications. Eight manuscripts and 20 studies from the grey literature were included in the final review. Most studies (54%) were literature reviews that indicated forensic nursing as an emerging specialty in Brazil, addressing educational, instructional, communicative or contextual aspects of the specialty in the country. In the nursing profession in Brazil, few studies exist on forensic nursing and those are limited to short communications. Although most studies address the definition of forensic nursing, others present its implications in various situations such as intimate partner violence, domestic violence, sexual abuse and elder mistreatment. Despite the study limitations, it provides evidence that forensic nursing has been silently implemented in the country with the need for more evidence-based studies to support its constitution as a specialty in Brazil. © 2016 International Council of Nurses.

    Nathan, Richard P

    2005-01-01

    This paper presents a cyclical theory of U.S. federalism and social policy: Many social policy initiatives are tested and refined at the state level, especially during conservative periods, and later morph into national policies. The paper describes such federalism cycles and offers an interpretation of why and how they occur, focusing on Medicaid. State activism has preserved and expanded Medicaid through policy innovation and resistance to retrenchment, especially in conservative periods, by taking advantage of the flexibility the program provides. I conclude that Medicaid's incremental/partnership approach is appropriate and feasible to build on for a future expansion of health care coverage.

    Full Text Available The Scatter Search (SS is a deterministic strategy that has been applied successfully to some combinatorial and continuous optimization problems. Cuckoo Search (CS is heuristic search algorithm which is inspired by the reproduction strategy of cuckoos. This paper presents enhanced scatter search algorithm using CS algorithm. The improvement provides Scatter Search with random exploration for search space of problem and more of diversity and intensification for promising solutions. The original and improved Scatter Search has been tested on Traveling Salesman Problem. A computational experiment with benchmark instances is reported. The results demonstrate that the improved Scatter Search algorithms produce better performance than original Scatter Search algorithm. The improvement in the value of average fitness is 23.2% comparing with original SS. The developed algorithm has been compared with other algorithms for the same problem, and the result was competitive with some algorithm and insufficient with another.

    2012-11-01

    As faculty members, we frequently find that first-year doctoral students in nursing are confused about how to conduct a systematic integrated literature review. This could be due to its vague definition and a lack of recent literature that provides directions for conducting a systematic integrated literature review. This article aims to provide directions for conducting a systematic integrated literature review by identifying the essential components of published literature reviews in nursing. To achieve this goal, the literature was searched by using the keywords nursing, systematic, and review in multiple databases. A total of 267 articles were selected and are included in this systematic integrated literature review. The articles were then sorted by study design and analyzed in six areas of interests. Finally, a practical guideline for conducting systematic integrated literature reviews is proposed based on the analysis of the literature.

  2. Automated Medical Literature Retrieval

    Full Text Available Background The constantly growing publication rate of medical research articles puts increasing pressure on medical specialists who need to be aware of the recent developments in their field. The currently used literature retrieval systems allow researchers to find specific papers; however the search task is still repetitive and time-consuming. Aims In this paper we describe a system that retrieves medical publications by automatically generating queries based on data from an electronic patient record. This allows the doctor to focus on medical issues and provide an improved service to the patient, with higher confidence that it is underpinned by current research. Method Our research prototype automatically generates query terms based on the patient record and adds weight factors for each term. Currently the patient’s age is taken into account with a fuzzy logic derived weight, and terms describing blood-related anomalies are derived from recent blood test results. Conditionally selected homonyms are used for query expansion. The query retrieves matching records from a local index of PubMed publications and displays results in descending relevance for the given patient. Recent publications are clearly highlighted for instant recognition by the researcher. Results Nine medical specialists from the Royal Adelaide Hospital evaluated the system and submitted pre-trial and post-trial questionnaires. Throughout the study we received positive feedback as doctors felt the support provided by the prototype was useful, and which they would like to use in their daily routine. Conclusion By supporting the time-consuming task of query formulation and iterative modification as well as by presenting the search results in order of relevance for the specific patient, literature retrieval becomes part of the daily workflow of busy professionals.

    In the past year the ATLAS Collaboration accelerated its program to federate data storage resources using an architecture based on XRootD with its attendant redirection and storage integration services. The main goal of the federation is an improvement in the data access experience for the end user while allowing more efficient and intelligent use of computing resources. Along with these advances come integration with existing ATLAS production services (PanDA and its pilot services) and data management services (DQ2, and in the next generation, Rucio). Functional testing of the federation has been integrated into the standard ATLAS and WLCG monitoring frameworks and a dedicated set of tools provides high granularity information on its current and historical usage. We use a federation topology designed to search from the site's local storage outward to its region and to globally distributed storage resources. We describe programmatic testing of various federation access modes including direct access over the w...

    2010-08-01

    Full Text Available A review of the recent literature suggests that users prefer simple search interfaces such as Google. The implication here is that libraries often fail to make their resources discoverable and that this may in turn affect the perceived value of the library. Against the background of the ongoing national debate about user expectations, a project group at the University of Huddersfield was asked to investigate the current provision for electronic resources and to look at a solution which would ‘provide ease of searching and access for the user, whilst reducing the workload for systems and technical services and remaining within current budget levels’. As a direct result of this review, the University of Huddersfield was the first UK commercial adopter of Summon in the summer of 2009. The Summon web-scale discovery service from Serials Solutions provides a simple single-search box to the breadth of the library's collection, swiftly delivering simultaneous information and results from the local catalogue and remote electronic resources offering a real alternative to the traditional federated search. This paper will provide a case study of the implementation, evaluation and launch of this radical new service to users at the University of Huddersfield, by detailing the approaches used and lessons learned throughout the implementation period and making recommendations for future enhancements.

    Full Text Available Despite a growing body of literature, substantial variance remains between researchers, mental health experts, clinicians, and practitioners over the nature, structure, and contents of psychosocial interventions aimed at reducing the mental health burden in war-torn and postconflict societies. We conducted a focused and systematic review of the literature published over the last two decades on the most commonly used psychotherapeutic treatment modalities in medical and humanitarian interventions as represented by expert opinion, observational and qualitative or mixed-method studies, case reports, case control, and community-based studies, excluding randomized controlled trials (RCTs and meta-analyses of RCTs. More specifically, we aimed at searching for best practices and supporting psychosocial interventions within the domain of adult mental health in civilian populations in low- and middle-income countries affected by protracted political violence, armed conflict, and wars. We noted the need to translate existing knowledge into action (know-do gap and the critical importance of applying qualitative evidence-based knowledge that informs and supports collective interventions and best practices in medical and humanitarian assistance programs currently being undertaken.

    2010-01-01

    Models of fiscal federalism rarely account for the efficiency implications of intergovernmental fiscal ties for federal tax policy. This paper shows that fiscal institutions such that federal tax deductibility, vertical revenue-sharing, and fiscal equalization (being common features of existing...... federations) encourage local taxation, but may discourage federal taxation. Furthermore, the structure of public spending is skewed towards local spending. We also show that, when considering Leviathan governments, fiscal institutions reduce confiscatory taxation by the federal government. The result...... is contrary to the Cartelization Hypothesis ( Brennan and Buchanan 1980 ). Finally, we characterize the efficient design of intergovernmental fiscal ties....

  1. SASL: A Semantic Annotation System for Literature

    Science.gov (United States)

    Yuan, Pingpeng; Wang, Guoyin; Zhang, Qin; Jin, Hai

    Due to ambiguity, search engines for scientific literatures may not return right search results. One efficient solution to the problems is to automatically annotate literatures and attach the semantic information to them. Generally, semantic annotation requires identifying entities before attaching semantic information to them. However, due to abbreviation and other reasons, it is very difficult to identify entities correctly. The paper presents a Semantic Annotation System for Literature (SASL), which utilizes Wikipedia as knowledge base to annotate literatures. SASL mainly attaches semantic to terminology, academic institutions, conferences, and journals etc. Many of them are usually abbreviations, which induces ambiguity. Here, SASL uses regular expressions to extract the mapping between full name of entities and their abbreviation. Since full names of several entities may map to a single abbreviation, SASL introduces Hidden Markov Model to implement name disambiguation. Finally, the paper presents the experimental results, which confirm SASL a good performance.

    2000-01-01

    This paper discusses the challenges of finding evidence needed to implement Evidence-Based Librarianship (EBL). Focusing first on database coverage for three health sciences librarianship journals, the article examines the information contents of different databases. Strategies are needed to search for relevant evidence in the library literature via these databases, and the problems associated with searching the grey literature of librarianship. Database coverage, plausible search strategies, and the grey literature of library science all pose challenges to finding the needed research evidence for practicing EBL. Health sciences librarians need to ensure that systems are designed that can track and provide access to needed research evidence to support Evidence-Based Librarianship (EBL).

    The paper deals with the application of the activity theory in describing psychological determinants of the information searching activity. The notions of information behavior, information retrieval, information competence, information retrieval activity given in Russian and English scientific literature are compared. The research approach to the information retrieval activity based on the principles developed in the Russian theory of activity is described; and the fundamentals of G. Sukhodolsky's generalized conception of activity are presented for the first time. Analysis of empirical researches showed that specific features of information search depend on how the user evaluates information resources, information, conditions and results of search. Psychological determiners of information search may be detected as the system of evaluative alternatives, which is generated by the user during the process of his experience growth. We discovered that user's evaluation system is also related to his individual typological and personal regulative features and determines the choice of the search strategy.

  5. Citation searches are more sensitive than keyword searches to identify studies using specific measurement instruments.

    2015-04-01

    To compare the effectiveness of two search methods in identifying studies that used the Control Preferences Scale (CPS), a health care decision-making instrument commonly used in clinical settings. We searched the literature using two methods: (1) keyword searching using variations of "Control Preferences Scale" and (2) cited reference searching using two seminal CPS publications. We searched three bibliographic databases [PubMed, Scopus, and Web of Science (WOS)] and one full-text database (Google Scholar). We report precision and sensitivity as measures of effectiveness. Keyword searches in bibliographic databases yielded high average precision (90%) but low average sensitivity (16%). PubMed was the most precise, followed closely by Scopus and WOS. The Google Scholar keyword search had low precision (54%) but provided the highest sensitivity (70%). Cited reference searches in all databases yielded moderate sensitivity (45-54%), but precision ranged from 35% to 75% with Scopus being the most precise. Cited reference searches were more sensitive than keyword searches, making it a more comprehensive strategy to identify all studies that use a particular instrument. Keyword searches provide a quick way of finding some but not all relevant articles. Goals, time, and resources should dictate the combination of which methods and databases are used.

    This article provides an overview of selected Web-based resources containing grey literature in the area of communication disorders. It is geared to practitioners, researchers, students, and consumers seeking reliable, freely available scientific information. Grey (or gray) literature has been defined as "that which is produced on all levels of government, academics, business, and industry in print and electronic formats, but which is not controlled by commercial publishers."1 This paper reviews various general reference sources potentially containing grey literature on communication disorders. This review includes identification of the methods specialists in this field use to obtain this valuable, yet often overlooked, literature. Access points and search tools for identifying grey literature on communication disorders are recommended. Commercial databases containing grey literature are not included. Conclusions presented in this article are considered complementary to traditionally published information resources on communication disorders, such as scholarly journals, online databases, etc.

    In the medical literature, there is little known about vaginal wind, though from clinical expertise, it turns out to be a consistent and underreported problem. The aim of this review was to collect the available literature about the different aspects of vaginal wind. A systematic literature search was conducted using three databases until December 2015. The search strategy was built using relevant synonyms of vaginal wind. Study characteristics were extracted. Risk of bias, the quality of the relevant studies and the level of evidence was judged. Eleven studies met the inclusion criteria. Vaginal wind occurs on random movements and during or after coitus. The prevalence ranges from one to 69%. The pathophysiology is unclear and the incidence unknown. Known risk factors are vaginal delivery and urinary incontinence. Provoking factors are coitus, digital stimulation, cunnilingus and exercising. Female sexual function is decreased. The sexual function of male partners with vaginal wind is not influenced. Overall vaginal wind leads to a decrease in the quality of live and can have cause social isolation. The treatment is related to the cause and mainly not successful. Tampons can be used for treatment as well as prevention. Vaginal wind is an underestimated health issue with a severe impact on sexual functioning. Adequate research is needed regarding the influence of sexual activity, weight, age, parity, the underlying pathophysiological mechanisms, prevention and treatment. Copyright © 2017 Elsevier B.V.

  18. Federation of Malaysia. Country profile.

    Science.gov (United States)

    Newcomb, L

    1985-01-01

    The 1984 population of Malaysia has been estimated at 14.7 million and the population growth rate averaged 2.3% in 1970-80. Population growth is officially encouraged to form a substantial home market for economic development. Toward this end, the 1985 budget has increased tax deductions for families with 5 children. The capital city of Kuala Lumpur is the largest metropolitan area (1 million population) and the Federal Territory is the most densely populated region. Immigration is strictly controlled by the government, and the percentage of foreign-born citizens was 5% in 1980. China, India, and Pakistan are decreasing in importance as countries of origin. Internal mobility, however, is increasing. Rural-rural migration accounted for 45% of internal migration in 1970-80 and was largely motivated by family reasons. Only 7% of Malaysians are estimated to move in search of work. Racial tensions led the government to grant special economic privileges to native-born Islamic Malays. The greatest proportion of the population is centered in the lowest age groups. The percentage of females 15-29 years of age rose from 26% in 1970 to 30% in 1980 and is expected to continue to rise. Fertility is on the decline. The majority of households in the country involve nuclear families. There has been an increase in the number of men and women who delay marriage or remain single. Education is widely available for children aged 6-15 years and those who meet certain academic standards receive free education up to age 19 years. The current labor force is estimated at 5.4 million, with an annual growth rate of 3.1%. Malaysia's per capita income (US $1860 in 1982) is among the highest in Southeast Asia and the gross national product increased by an average annual rate of 8% in 1970-81. The government plans to move toward the development of heavier industries and more manufacturing concerns.

    2012-12-01

    During its 20 years of R&D, construction and operation the PHENIX experiment at the Relativistic Heavy Ion Collider (RHIC) has accumulated large amounts of proprietary collaboration data that is hosted on many servers around the world and is not open for commercial search engines for indexing and searching. The legacy search infrastructure did not scale well with the fast growing PHENIX document base and produced results inadequate in both precision and recall. After considering the possible alternatives that would provide an aggregated, fast, full text search of a variety of data sources and file formats we decided to use Nutch [1] as a web crawler and Solr [2] as a search engine. To present XML-based Solr search results in a user-friendly format we use Drupal [3] as a web interface to Solr. We describe the experience of building a federated search for a heterogeneous collection of 10 million PHENIX documents with Nutch, Solr and Drupal.

    2012-01-01

    Fascia is virtually inseparable from all structures in the body and acts to create continuity amongst tissues to enhance function and support. In the past fascia has been difficult to study leading to ambiguities in nomenclature, which have only recently been addressed. Through review of the available literature, advances in fascia research were compiled, and issues related to terminology, descriptions, and clinical relevance of fascia were addressed. Our multimodal search strategy was conducted in Medline and PubMed databases, with other targeted searches in Google Scholar and by hand, utilizing reference lists and conference proceedings. In an effort to organize nomenclature for fascial structures provided by the Federative International Committee on Anatomical Terminology (FICAT), we developed a functional classification system which includes four categories of fascia: i) linking, ii) fascicular, iii) compression, and iv) separating fasciae. Each category was developed from descriptions in the literature on gross anatomy, histology, and biomechanics; the category names reflect the function of the fascia. An up-to-date definition of fascia is provided, as well as descriptions of its function and clinical features. Our classification demonstrates the use of internationally accepted terminology in an ontology which can improve understanding of major terms in each category of fascia. PMID:22997468

  6. Information retrieval in digital libraries: bringing search to the net.

    1997-01-17

    A digital library enables users to interact effectively with information distributed across a network. These network information systems support search and display of items from organized collections. In the historical evolution of digital libraries, the mechanisms for retrieval of scientific literature have been particularly important. Grand visions in 1960 led first to the development of text search, from bibliographic databases to full-text retrieval. Next, research prototypes catalyzed the rise of document search, from multimedia browsing across local-area networks to distributed search on the Internet. By 2010, the visions will be realized, with concept search enabling semantic retrieval across large collections.

  13. Automatization and training in visual search.

    Czerwinski, M; Lightfoot, N; Shiffrin, R M

    1992-01-01

    In several search tasks, the amount of practice on particular combinations of targets and distractors was equated in varied-mapping (VM) and consistent-mapping (CM) conditions. The results indicate the importance of distinguishing between memory and visual search tasks, and implicate a number of factors that play important roles in visual search and its learning. Visual search was studied in Experiment 1. VM and CM performance were almost equal, and slope reductions occurred during practice for both, suggesting the learning of efficient attentive search based on features, and no important role for automatic attention attraction. However, positive transfer effects occurred when previous CM targets were re-paired with previous CM distractors, even though these targets and distractors had not been trained together. Also, the introduction of a demanding simultaneous task produced advantages of CM over VM. These latter two results demonstrated the operation of automatic attention attraction. Visual search was further studied in Experiment 2, using novel characters for which feature overlap and similarity were controlled. The design and many of the findings paralleled Experiment 1. In addition, enormous search improvement was seen over 35 sessions of training, suggesting the operation of perceptual unitization for the novel characters. Experiment 3 showed a large, persistent advantage for CM over VM performance in memory search, even when practice on particular combinations of targets and distractors was equated in the two training conditions. A multifactor theory of automatization and attention is put forth to account for these findings and others in the literature.

    The universe of potentially interesting, searchable literature is expanding continuously. Besides the normal expansion, there is an additional influx of literature because of interdisciplinary boundaries becoming more and more diffuse. Hence, the need for accurate, efficient and intelligent search tools is bigger than ever. Even with a sophisticated search engine, looking for information can still result in overwhelming results. An overload of information has the intrinsic danger of scaring visitors away, and any organization, for-profit or not-for-profit, in the business of providing scholarly information wants to capture and keep the attention of its target audience. Publishers and search engine engineers alike will benefit from a service that is able to provide visitors with recommendations that closely meet their interests. Providing visitors with special deals, new options and highlights may be interesting to a certain degree, but what makes more sense (especially from a commercial point of view) than to...

    The purpose of the study described in this report is to summarize the various barriers to more widespread distribution of bio-fuels through our common carrier fuel distribution system, which includes pipelines, barges and rail, fuel tankage, and distribution terminals. Addressing these barriers is necessary to allow the more widespread utilization and distribution of bio-fuels, in support of a renewable fuels standard and possible future low-carbon fuel standards. These barriers can be classified into several categories, including operating practice, regulatory, technical, and acceptability barriers. Possible solutions to these issues are discussed; including compatibility evaluation, changes to bio-fuels, regulatory changes, and changes in the distribution system or distribution practices. No actual experimental research has been conducted in the writing of this report, but results are used to develop recommendations for future research and additional study as appropriate. This project addresses recognized barriers to the wider use of bio-fuels in the areas of development of codes and standards, industrial and consumer awareness, and materials compatibility issues.

As a way of overcoming these limitations and potentiating a more efficient use of the literature, we propose an approach for structuring the results of a literature search based on the latent semantic information extracted from a corpus. Moreover, we show how the results of the Latent Semantic Analysis method can be adapted so as to evidence differences between results of different searches. We also propose different visualization techniques that can be applied to explore these results. Used in combination, these techniques could empower users with tools for literature guided knowledge exploration and discovery.

  9. Search, Memory, and Choice Error: An Experiment.

    Directory of Open Access Journals (Sweden)

    Adam Sanjurjo

    Full Text Available Multiple attribute search is a central feature of economic life: we consider much more than price when purchasing a home, and more than wage when choosing a job. An experiment is conducted in order to explore the effects of cognitive limitations on choice in these rich settings, in accordance with the predictions of a new model of search memory load. In each task, subjects are made to search the same information in one of two orders, which differ in predicted memory load. Despite standard models of choice treating such variations in order of acquisition as irrelevant, lower predicted memory load search orders are found to lead to substantially fewer choice errors. An implication of the result for search behavior, more generally, is that in order to reduce memory load (thus choice error a limited memory searcher ought to deviate from the search path of an unlimited memory searcher in predictable ways-a mechanism that can explain the systematic deviations from optimal sequential search that have recently been discovered in peoples' behavior. Further, as cognitive load is induced endogenously (within the task, and found to affect choice behavior, this result contributes to the cognitive load literature (in which load is induced exogenously, as well as the cognitive ability literature (in which cognitive ability is measured in a separate task. In addition, while the information overload literature has focused on the detrimental effects of the quantity of information on choice, this result suggests that, holding quantity constant, the order that information is observed in is an essential determinant of choice failure.

  10. BIOMedical Search Engine Framework: Lightweight and customized implementation of domain-specific biomedical search engines.

    Jácome, Alberto G; Fdez-Riverola, Florentino; Lourenço, Anália

    2016-07-01

    Text mining and semantic analysis approaches can be applied to the construction of biomedical domain-specific search engines and provide an attractive alternative to create personalized and enhanced search experiences. Therefore, this work introduces the new open-source BIOMedical Search Engine Framework for the fast and lightweight development of domain-specific search engines. The rationale behind this framework is to incorporate core features typically available in search engine frameworks with flexible and extensible technologies to retrieve biomedical documents, annotate meaningful domain concepts, and develop highly customized Web search interfaces. The BIOMedical Search Engine Framework integrates taggers for major biomedical concepts, such as diseases, drugs, genes, proteins, compounds and organisms, and enables the use of domain-specific controlled vocabulary. Technologies from the Typesafe Reactive Platform, the AngularJS JavaScript framework and the Bootstrap HTML/CSS framework support the customization of the domain-oriented search application. Moreover, the RESTful API of the BIOMedical Search Engine Framework allows the integration of the search engine into existing systems or a complete web interface personalization. The construction of the Smart Drug Search is described as proof-of-concept of the BIOMedical Search Engine Framework. This public search engine catalogs scientific literature about antimicrobial resistance, microbial virulence and topics alike. The keyword-based queries of the users are transformed into concepts and search results are presented and ranked accordingly. The semantic graph view portraits all the concepts found in the results, and the researcher may look into the relevance of different concepts, the strength of direct relations, and non-trivial, indirect relations. The number of occurrences of the concept shows its importance to the query, and the frequency of concept co-occurrence is indicative of biological relations

    The Energy Information Administration (EIA) of the US Department of Energy (DOE) is mandated by Congress to be the agency that collects, analyzes, and disseminates impartial, comprehensive data about energy including the volume consumed, its customers, and the purposes for which it is used. The Federal Buildings Supplemental Survey (FBSS) was conducted by EIA in conjunction with DOE`s Office of Federal Energy Management Programs (OFEMP) to gain a better understanding of how Federal buildings use energy. This report presents the data from 881 completed telephone interviews with Federal buildings in three Federal regions. These buildings were systematically selected using OFEMP`s specifications; therefore, these data do not statistically represent all Federal buildings in the country. The purpose of the FBSS was threefold: (1) to understand the characteristics of Federal buildings and their energy use; (2) to provide a baseline in these three Federal regions to measure future energy use in Federal buildings as required in EPACT; and (3) to compare building characteristics and energy use with the data collected in the CBECS.

We focus on such search strategies within the domain of sustainable innovation in which problems are inherently complex and the relevant knowledge is widely...... dispersed. Hence, firms need to collaborate. We shed new light on collaborative search strategies led by firms in general and for solving environmental problems in particular. Both topics are largely absent in the extant open innovation literature. Using data from the European Seventh Framework Program...... for Research and Technological Development (FP7), our results indicate that the problem-solving potential of a search strategy increases with the diversity of existing knowledge of the partners in a consortium and with the experience of the partners involved.

    Full Text Available Existen dos discursos contrapuestos al respecto de la cuestión del consumo de drogas: el tradicional, que considera sólo a las drogas ilegales, criminalizando al usuario y uno nuevo, denominado de reducción de daños, que no tiene como objetivo único su eliminación total, sino también la disminución de los efectos perjudiciales del mismo, priorizando así la salud de los sujetos y de la comunidad en general. En el marco particular de las instituciones públicas del Distrito Federal, Brasil, se analizan tanto el tipo de discursos predominantes en cada una de ellas, como las relaciones de poder que permiten y organizan. Se consideran en particular los niveles de gestión responsables por determinar y ejecutar las políticas de prevención y atención a las toxicomanías. El Análisis do Discurso, utilizado en este trabajo permite el análisis de las entrevistas realizadas en las instituciones. La discusión de este tema contribuye para pensar un cambio en las políticas públicas en esta área que permita el aprovechamiento integral de los recursos humanos e institucionales existentes.

    The European Bioinformatics Institute (EMBL-EBI-https://www.ebi.ac.uk) provides free and unrestricted access to data across all major areas of biology and biomedicine. Searching and extracting knowledge across these domains requires a fast and scalable solution that addresses the requirements of domain experts as well as casual users. We present the EBI Search engine, referred to here as 'EBI Search', an easy-to-use fast text search and indexing system with powerful data navigation and retrieval capabilities. API integration provides access to analytical tools, allowing users to further investigate the results of their search. The interconnectivity that exists between data resources at EMBL-EBI provides easy, quick and precise navigation and a better understanding of the relationship between different data types including sequences, genes, gene products, proteins, protein domains, protein families, enzymes and macromolecular structures, together with relevant life science literature.

  8. Faceted Semantic Search for Personalized Social Search

    CERN Document Server

    Mas, Massimiliano Dal

    2012-01-01

    Actual social networks (like Facebook, Twitter, Linkedin, ...) need to deal with vagueness on ontological indeterminacy. In this paper is analyzed the prototyping of a faceted semantic search for personalized social search using the "joint meaning" in a community environment. User researches in a "collaborative" environment defined by folksonomies can be supported by the most common features on the faceted semantic search. A solution for the context-aware personalized search is based on "joint meaning" understood as a joint construal of the creators of the contents and the user of the contents using the faced taxonomy with the Semantic Web. A proof-of concept prototype shows how the proposed methodological approach can also be applied to existing presentation components, built with different languages and/or component technologies.

    1981-01-01

    The Federal Mining Law is a codification of mining law in the Federal Republic of Germany. It contains 178 paragraphs covering all aspects of prospecting and mining of mineral raw materials and related activities. The new law is to replace the former regional mining laws as well as most of the former Federal and regional regulations. All in all, 104 laws and regulations are repealed in sections 174 and 175. Basic principles of the former mining laws have been adhered to, e.g. mineral reserves do not come under the proprietory rights of the land owner, preventive monitoring of operations by means of operation plans, cession of territory under mining law, and the regulations concerning mining and land ownership. However, there are new details in the Federal Mining Law, in particular with regard to concessions and mining damage; this is reflected in a more complicated legal language.

    Large neighborhood search is a metaheuristic that has gained popularity in recent years. The heuristic repeatedly moves from solution to solution by first partially destroying the solution and then repairing it. The best solution observed during this search is presented as the final solution....... This tutorial introduces the large neighborhood search metaheuristic and the variant adaptive large neighborhood search that dynamically tunes parameters of the heuristic while it is running. Both heuristics belong to a broader class of heuristics that are searching a solution space using very large...... neighborhoods. The tutorial also present applications of the adaptive large neighborhood search, mostly related to vehicle routing problems for which the heuristic has been extremely successful. We discuss how the heuristic can be parallelized and thereby take advantage of modern desktop computers...

    This paper presents findings from a laboratory experiment on human decision-making in a complex combinatorial task. We find strong evidence for a behavioral model of adaptive search. Success narrows down search to the neighborhood of the status quo, while failure promotes gradually more explorative...... search. Task complexity does not have a direct effect on behavior, but systematically affects the feedback conditions that guide success-induced exploitation and failure-induced exploration. The analysis also shows that human participants were prone to over-exploration, since they broke off the search...... for local improvements too early. We derive stylized decision rules that generate the search behavior observed in the experiment and discuss the implications of our findings for individual decision-making and organizational search....

    Directory of Open Access Journals (Sweden)

    2012-11-01

    Full Text Available In three studies, we examined factors that may temporarily attenuate information search. People are generally curious and dislike uncertainty, which typically encourages them to look for relevant information. Despite these strong forces that promote information search, people sometimes deliberately delay obtaining valuable information. We find they may do so when they are concerned that the information might interfere with future pleasurable activities. Interestingly, the decision to search or to postpone searching for information is influenced not only by the value and importance of the information itself but also by well-being maintenance goals related to possible detrimental effects that negative knowledge may have on unrelated future plans.

    School breakfast programs are widespread and serve varying objectives regarding youth health promotion. Evidence-based guidelines for breakfast programs may be important in maximizing their effectiveness related to student outcomes, yet it is unclear what is available in Canada. A systematic review was conducted to identify and compare Canadian guidelines related to breakfast programs. Data sources included grey literature databases, customized search engines, targeted websites, and content expert consultations. Eligible guidelines met the following criteria: government and nongovernment sources at the federal and provincial/territorial levels, current version, and intended for program coordinators. Recommendations for program delivery were extracted, categorized, and mapped onto the 4 environments outlined in the ANGELO framework, and they were classified as "common" or "inconsistent" across guidelines. Fifteen sets of guidelines were included. No guidelines were available from federal or territorial governments and 4 provincial governments. There were few references to peer-reviewed literature within the guidelines and despite many common recommendations for program delivery, conflicting recommendations were also identified. Potential barriers to program participation, including a lack of consideration of allergies and other dietary restrictions, were identified. Future research should identify how guidelines are implemented and evaluate what effect their implementation has on program delivery and student outcomes.
