    2005-01-01

    Two years after the initial 2002 study, a greater number of academic health science libraries are offering digital reference chat services, and this number appears poised to grow in the coming years. This 2004 follow-up study found that 36 (27%) of the academic health science libraries examined provide digital chat reference services; this was an approximately 6% increase over the 25 libraries (21%) located in 2002. Trends in digital reference services in academic health science libraries were derived from the exploration of academic health science library Web sites and from digital correspondence with academic health science library personnel using e-mail and chat. This article presents an overview of the current state of digital reference service in academic health science libraries.

    Schulte, Stephanie J

    2011-01-01

    Question: How were traditional librarian reference desk services successfully eliminated at one health sciences library? Setting: The analysis was done at an academic health sciences library at a major research university. Method: A gap analysis was performed, evaluating changes in the first eleven months through analysis of reference transaction and instructional session data. Main Results: Substantial increases were seen in the overall number of specialized reference transactions and those conducted by librarians lasting more than thirty minutes. The number of reference transactions overall increased after implementing the new model. Several new small-scale instructional initiatives began, though perhaps not directly related to the new model. Conclusion: Traditional reference desk services were eliminated at one academic health sciences library without negative impact on reference and instructional statistics. Eliminating ties to the confines of the physical library due to staffing reference desk hours removed one significant barrier to a more proactive liaison program. PMID:22022221

    Science.gov (United States)

    Marshall, J G; Buchanan, H S

    1995-01-01

    Benchmarking is based on the common sense idea that someone else, either inside or outside of libraries, has found a better way of doing certain things and that your own library's performance can be improved by finding out how others do things and adopting the best practices you find. Benchmarking is one of the tools used for achieving continuous improvement in Total Quality Management (TQM) programs. Although benchmarking can be done on an informal basis, TQM puts considerable emphasis on formal data collection and performance measurement. Used to its full potential, benchmarking can provide a common measuring stick to evaluate process performance. This article introduces the general concept of benchmarking, linking it whenever possible to reference services in health sciences libraries. Data collection instruments that have potential application in benchmarking studies are discussed and the need to develop common measurement tools to facilitate benchmarking is emphasized.

    Electronic Access to Reference Service (EARS) is a front end to the Health Sciences Library's electronic mail system, with links to the online public catalog. EARS, which became operational in September 1984, is accessed by users at remote sites with either a terminal or microcomputer. It is menu-driven, allowing users to request: a computerized literature search, reference information, a photocopy of a journal article, or a book. This paper traces the history of EARS and discusses its use, its impact on library staff and services, and factors that influence the diffusion of new technology.

    Full Text Available Objective – To investigate the current organizational models for reference work in Australian academic libraries, and how these reference services are staffed.Design – Mixed methods.Setting – Academic universities in Australia.Subjects – Forty Council of Australian University Librarians (CAUL member libraries.Methods – A literature study was undertaken to (1 find a definition of reference services and (2 explore the development of reference service models over time. Statistics from the CAUL member libraries were studied for trends in student population and number of academic and library staff. A web‐based survey, with questions based on the findings in the literature study, was then distributed to the 40 Australian university libraries in 2006. Respondents were asked when the library commenced different reference services in five areas: formats in which the library received and responded to reference queries, information literacy, subject specialization, liaison activities, and collection development. Respondents also answered questions about the organization of the reference department, including: whether they had a separate or integrated model; the size of the reference collections; if they had a librarian dedicated to supporting students studying in remote or distant mode; if the interlibrary loans department was part of the suite of reference services; and if they had a mission or statement of purpose for their reference services department.Main Results – Based on the literature study, the working definition of reference services (1 for the project was “all activities which assist in providing relevant and appropriate information services to patrons” (270, including:•All interactions with patrons to assist them in their searches for information in all media types.•All training by librarians of patrons to be able to access information for themselves.•Activities to help the library stay informed of relevant developments

    2011-11-01

    Full Text Available Roaming reference service was pursued as a way to address declining reference statistics. The service was staffed by librarians armed with iPads over a period of six months during the 2010-2011 academic year. Transactional statistics were collected in relation to query type (Research, Facilitative or Technology, location and approach (librarian to patron, patron to librarian or via chat widget. Overall, roaming reference resulted in an additional 228 reference questions, 67% (n=153 of which were research related. Two iterations of the service were implemented, roaming reference as a standalone service (Fall 2010 and roaming reference integrated with traditional reference desk duties (Winter 2011. The results demonstrate that although the Weller Library’s reference transactions are declining annually, they are not disappearing. For a roaming reference service to succeed, it must be a standalone service provided in addition to traditional reference services. The integration of the two reference models (roaming reference and reference desk resulted in a 56% decline in the total number of roaming reference questions from the previous term. The simple act of roaming has the potential to reinvigorate reference services as a whole, forcing librarians outside their comfort zones, allowing them to reach patrons at their point of need.

    Full Text Available Objective - To identify similarities and difference in the questions asked at the virtual and physical refernece desks of a helath scienmces library, in order to better undertand user needs and highlight areas for service improvement. Also to retrospectively analyze reference statistics collected over the previous six years. Design - Use study; retrospective study of reference statistics for the period July 1997 to June 2003; literature review. Setting - Large academic helath sciences library in the United States. Subjects - All questions asked at the reference and information desks, plus questions submitted to the University-wide virtual reference service and answered by a health sciences librarian, over a period of one month. The questions were asked by faculty, staff, students and members of the public. Methods - A literature review was carried out to examine the types of information/reference questions typically asked in health sciences libraries both before and after the mass introduction of remote end-user searching of online resources and the establishment of virtual reference services. Next, the reference statistics collected at the University of Illinois at Chicage (UIC Library of the Health Sciences between July 1997 and June 2003 were examined. For most of this period a digital reference service was offered using a listserv address to which patrons would submit email queries. Beginning in March 2003, a formal virtual reference service (chat and email was provided using commercial software. Finally, data was gathered on questions answered by a health sciences librarians, and clients who asked the question, at either the physical or cirtual reference desk, during the month of November 2003 at the UIC Library of the Health Sciences.

    Full Text Available Introduction. This study investigated unmonitored referrals in a nationwide, collaborative chat reference service. Specifically, it examined the extent to which questions are referred, the types of questions that are more likely to be referred than others, and the level of user satisfaction with the referrals in the collaborative chat reference service. Method. The data analysed for this study were 420 chat reference transaction transcripts along with corresponding online survey questionnaires submitted by the service users. Both sets of data were collected from an electronic archive of a southeastern state public library system that has participated in 24/7 Reference of the Metropolitan Cooperative Library System (MCLS. Results. Referrals in the collaborative chat reference service comprised approximately 30% of the total transactions. Circulation-related questions were the most often referred among all question types, possibly because of the inability of 'outside' librarians to access patron accounts. Most importantly, user satisfaction with referrals was found to be significantly lower than that of completed answers. Conclusion. The findings of this study addressed the importance of distinguishing two types of referrals: the expert research referrals conducive to collaborative virtual reference services; and the re-directional local referrals that increase unnecessary question traffic, thereby being detrimental to effective use of collaborative reference. Continuing efforts to conceptualize referrals in multiple dimensions are anticipated to fully grasp complex phenomena underlying referrals.

  11. Asynchronous Message Service Reference Implementation

    Science.gov (United States)

    Burleigh, Scott C.

    2011-01-01

    This software provides a library of middleware functions with a simple application programming interface, enabling implementation of distributed applications in conformance with the CCSDS AMS (Consultative Committee for Space Data Systems Asynchronous Message Service) specification. The AMS service, and its protocols, implement an architectural concept under which the modules of mission systems may be designed as if they were to operate in isolation, each one producing and consuming mission information without explicit awareness of which other modules are currently operating. Communication relationships among such modules are self-configuring; this tends to minimize complexity in the development and operations of modular data systems. A system built on this model is a society of generally autonomous, inter-operating modules that may fluctuate freely over time in response to changing mission objectives, modules functional upgrades, and recovery from individual module failure. The purpose of AMS, then, is to reduce mission cost and risk by providing standard, reusable infrastructure for the exchange of information among data system modules in a manner that is simple to use, highly automated, flexible, robust, scalable, and efficient. The implementation is designed to spawn multiple threads of AMS functionality under the control of an AMS application program. These threads enable all members of an AMS-based, distributed application to discover one another in real time, subscribe to messages on specific topics, and to publish messages on specific topics. The query/reply (client/server) communication model is also supported. Message exchange is optionally subject to encryption (to support confidentiality) and authorization. Fault tolerance measures in the discovery protocol minimize the likelihood of overall application failure due to any single operational error anywhere in the system. The multi-threaded design simplifies processing while enabling application nodes to

    At an academic health science center, librarians identified problems, weaknesses, and strengths in reference services. The on-call reference schedule was discontinued and a question flowchart was developed for circulation staff. Only research questions were referred to librarians, who would respond if available. Circulation staff perceived the unscheduled, voluntary model was not working well for the patrons or the staff. After two months, the schedule was reinstated with a hybrid version of the previous on-call format. In the process of changing the service model, the library staff also underwent a cultural change.

    Full Text Available Objective – To investigate the reasons behind the cessation of 9 virtual (chat reference services.Design – Multiple case‐study investigationSetting – Academic, public, and special libraries in the United States.Subjects – Five academic libraries, 1 public library, and 3 library consortia.Methods – The initial method used to identify discontinued chat reference services was via a posting to DIG_REF, the digitalreference services listserv. From this initial posting, librarians on the list also suggested other cases, for a total of 7. Two cases later came to the authors’ attention and were added. The 9 cases included academic libraries, a public library, and consortia who used tools provided by four major software vendors, giving a good cross‐section of the types of libraries participating in VR and the major software packages available at the time. A contact person for each discontinued service was invited to participate. The participants were geographically scattered, so data were collected via e‐mail questionnaires, telephone interviews, and examination of available documents describing the services, audiences, demographics, operations, and any decision‐making processes either for starting or discontinuing the service. The authors then compared and contrasted results obtained from the 9 services. The authors analysed reasons for discontinuation of services, the decision making processes, volume of questions, service hours, marketing, evaluation, and whether the service might be restarted atsome time in the future.Main Results – Although the VR services discussed were being delivered by diverse organizations, some commonalities emerged. All 9 services used existing staff and added chat reference to their duties. In all but one case, the hours of service offered when VRbegan were within the hours that the libraries were already open to the public.

    2008-01-01

    To allow scientists further capabilities in the area of data mining and web services, the Goddard Earth Sciences Data and Information Services Center (GES DISC) and researchers at the University of Alabama in Huntsville (UAH) have developed a system to mine data at the source without the need of network transfers. The system has been constructed by linking together several pre-existing technologies: the Simple Scalable Script-based Science Processor for Measurements (S4PM), a processing engine at he GES DISC; the Algorithm Development and Mining (ADaM) system, a data mining toolkit from UAH that can be configured in a variety of ways to create customized mining processes; ActiveBPEL, a workflow execution engine based on BPEL (Business Process Execution Language); XBaya, a graphical workflow composer; and the EOS Clearinghouse (ECHO). XBaya is used to construct an analysis workflow at UAH using ADam components, which are also installed remotely at the GES DISC, wrapped as Web Services. The S4PM processing engine searches ECHO for data using space-time criteria, staging them to cache, allowing the ActiveBPEL engine to remotely orchestras the processing workflow within S4PM. As mining is completed, the output is placed in an FTP holding area for the end user. The goals are to give users control over the data they want to process, while mining data at the data source using the server's resources rather than transferring the full volume over the internet. These diverse technologies have been infused into a functioning, distributed system with only minor changes to the underlying technologies. The key to the infusion is the loosely coupled, Web-Services based architecture: All of the participating components are accessible (one way or another) through (Simple Object Access Protocol) SOAP-based Web Services.

    A revised list of reference samples of interest to geoscientists has been extended to include samples for the agronomist, the archaeologist and the environmentalist. In addition to the source from which standard samples may be obtained, references or pertinent notes for some samples are included. The number of rock reference samples is now almost adequate, and the variety of ore samples will soon be sufficient. There are very few samples for microprobe work. Oil shales will become more important because of the outlook for world petroleum resources. The dryland equivalent of a submarine basalt might be useful in studies of sea-floor spreading and of the geochemistry of basalts. The Na- and K-feldspars of BCS (British Chemical Standards-Bureau of Analysed Samples), NBS (National Bureau of Standards), and ANRT (Association Kationale de la Recherche Technique) could serve as trace-element standards if such data were available. Similarly, the present NBS flint and plastic clays, as well as their predecessors, might be useful for archaeological pottery studies. The International Decade for Ocean Exploration may stimulate the preparation of ocean-water standards for trace elements or pollutants and a standard for manganese nodules. ?? 1974.

    Full Text Available A mixed methodological approach was used to explore to what extent the science curriculum was being reflected in science teaching-learning of grade VIII students in Bangladesh. 160 students were randomly selected and 10 science teachers were purposively selected as study respondents. Fifteen science lessons were observed. Data were collected via student questionnaires, teacher interviews, and classroom observation checklists. Grade VIII science teaching-learning activities were not conducted according to the instructions of the science curriculum. Most teachers did not adhere to the curriculum and teacher's guide. Teachers mainly depended on lecture methods for delivering lessons. Learning by doing, demonstrating experiments, scientific inquiry, rational thinking, and analysing cause-effect relationships were noticeably absent. Teachers reported huge workloads and a lack of ingredients as reasons for not practising these activities. Teachers did not use teaching aids properly. Science teaching-learning was fully classroom centred, and students were never involved in any creative activities.

    The School of Public Health at Saint Louis University is located at a greater distance from the library than other programs on the main medical center campus. Physical distance diminishes the ease of access to direct reference services for public health users. To bridge the gap, the library developed the Mobile Reference Service to deliver on-site information assistance with regular office hours each week. Between September 2006 and April 2007, a total of 57 in-depth reference transactions took place over 25 weeks, averaging 2 transactions per week in a 2-hour period. Overall reference transactions from public health users went up 28%, while liaison contacts with public health users doubled compared to the same period the year before. The Mobile Reference Service program has improved library support for research and scholarship, cultivated and strengthened liaison relationships, and enhanced marketing and delivery of library resources and services to the Saint Louis University School of Public Health.

    The widespread adoption of standard packet-based data communication protocols and services for spaceflight missions provides the foundation for other standard space data handling services. These space data handling services can be defined as increasingly sophisticated processing of data or information received from lower-level services, using a layering approach made famous in the International Organization for Standardization (ISO) Open System Interconnection Reference Model (OSI-RM). The Space Data System Interconnection Reference Model (SDSI-RM) incorporates the conventions of the OSIRM to provide a framework within which a complete set of space data handling services can be defined. The use of the SDSI-RM is illustrated through its application to data handling services and protocols that have been defined by, or are under consideration by, the Consultative Committee for Space Data Systems (CCSDS).

    2004-04-01

    A user-focused design approach was taken to develop a new "live reference" service at the Health Sciences Library, University of Saskatchewan. The name of the service, the placement of the links, and the design of a graphical button were seen as key elements in creating service awareness and its subsequent use. To ensure library users recognized and understood the label for the new service, selected library users were given an opportunity to choose a phrase that would best describe the service. The top two preferred phrases were then placed on the library Web pages as text and graphic images for further testing. Some pages had links in multiple locations to determine which placement worked best. Task-based usability testing was carried out with participants who were unaware of the new service. Participants were observed as they completed seven Website tasks arranged in increasing levels of difficulty to see whether they would notice the live reference service and seek assistance. The high level of recognition and use of the service indicate that the label name and link placement were effective with library Website users. Using user-centered design methodology helped ensure that the new live reference service was visible and used and demonstrated the effectiveness of the user-centered design approach for adding new services to an existing Website.

    The USA hCG Reference Service has been dealing with cases of persistent low levels of hCG and gestational trophoblastic diseases for 10years. Here we present the complete experience. Total hCG in serum and urine was measured using the Siemen's Immulite 1000 assay. Hyperglycosylated hCG, nicked hCG, free ss-subunit and ss-core fragment were measured using microtiterplate assays with antibodies B152, B151, FBT11 and B210, respectively. The USA hCG Reference Service has identified 83 cases of false-positive hCG, 71 cases of aggressive gestational trophoblastic disease (GTD), 52 cases of minimally invasive GTD, 168 cases of quiescent GTD and 22 cases of placenta site trophoblastic tumor (PSTT). In addition, 103 cases of pituitary hCG have been identified, 60 cases of nontrophoblastic tumor, 4 cases of inherited hCG and 2 cases of Munchausen's syndrome. This is 565 cases total. Multiple new methods are described and tested for diagnosing all of these disorders. The USA hCG Reference Service experience shows new methods for detecting multiple hCG-related disorders and recommends new approaches for detecting these hCG-related disorders. 2010 The Canadian Society of Clinical Chemists.

    To question the usefulness of the lab analysis considered routine testing for the identification of abnormalities in the surgical care. To determine the percentage of unnecessary laboratory tests in the preoperative assessment as well as to estimate the unnecessary expenses. A descriptive, cross-sectional study of patients referred for surgical evaluation between January 1st and March 31st 2013. The database of laboratory testing and electronic files were reviewed. Reference criteria from surgical services were compared with the tests requested by the family doctor. In 65% of the patients (n=175) unnecessary examinations were requested, 25% (n=68) were not requested the tests that they required, and only 10% of the patients were requested laboratory tests in accordance with the reference criteria (n=27). The estimated cost in unnecessary examinations was $1,129,552 in a year. The results were similar to others related to this theme, however, they had not been revised from the perspective of the first level of attention regarding the importance of adherence to the reference criteria which could prevent major expenditures. It is a priority for leaders and operational consultants in medical units to establish strategies and lines of action that ensure compliance with institutional policies so as to contain spending on comprehensive services, and which in turn can improve the medical care.

    Global Mapping Project, Web-enabled Landsat Data (WELD), International Satellite Land Surface Climatology Project (ISLSCP), hydrology, solid earth dynamics, sedimentary geology, climate modeling, integrated assessments and so on all have needs for or have worked to develop consistently integrated data layers for Earth and environmental science. This paper will present an overview of an abstract notion of data layers of this types, what we are referring to as reference data layers for Earth and environmental science, highlight some historical examples, and delve into new approaches. The concept of reference data layers in this context combines data availability, cyberinfrastructure and data science, as well as domain science drivers. We argue that current advances in cyberinfrastructure such as iPython notebooks and integrated science processing environments such as iPlant's Discovery Environment coupled with vast arrays of new data sources warrant another look at the how to create, maintain, and provide reference data layers. The goal is to provide a context for understanding science needs for reference data layers to conduct their research. In addition, to the topics described above this presentation will also outline some of the challenges to and present some ideas for new approaches to addressing these needs. Promoting the idea of reference data layers is relevant to a number of existing related activities such as EarthCube, RDA, ESIP, the nascent NSF Regional Big Data Innovation Hubs and others.

It offers several challenges for Service Science and Service Innovation. the goal of the presentation is to stimulate thinking about how service systems viII evolve in the future, as human society advances from its terrestrial base toward a permanent presence in space. First we will consider the complexity of the International Space Station (ISS) as it is today, with particular emphasis of its research facilities, and focus on a current challenge - to maximize the utilization of ISS research facilities for the benefit of society. After briefly reviewing the basic principles of Service Science, we will discuss the potential application of Service Innovation methodology to this challenge. Then we viII consider how game-changing technologies - in particular Synthetic Biology - could accelerate the pace of sociocultural evolution and consequently, the progression of human society into space. We will use this provocative vision to advance thinking about how the emerging field of Service Science, Management, and Engineering (SSME) might help us anticipate and better handle the challenges of this inevitable evolutionary process.

    The Planetary Data System (PDS) has undertaken an effort to overhaul the PDS data architecture (including the data model, data structures, data dictionary, etc.) and to deploy an upgraded software system (including data services, distributed data catalog, etc.) that fully embraces the PDS federation as an integrated system while taking advantage of modern innovations in information technology (including networking capabilities, processing speeds, and software breakthroughs). A core component of this new system is the Registry Service that will provide functionality for tracking, auditing, locating, and maintaining artifacts within the system. These artifacts can range from data files and label files, schemas, dictionary definitions for objects and elements, documents, services, etc. This service offers a single reference implementation of the registry capabilities detailed in the Consultative Committee for Space Data Systems (CCSDS) Registry Reference Model White Book. The CCSDS Reference Model in turn relies heavily on the Electronic Business using eXtensible Markup Language (ebXML) standards for registry services and the registry information model, managed by the OASIS consortium. Registries are pervasive components in most information systems. For example, data dictionaries, service registries, LDAP directory services, and even databases provide registry-like services. These all include an account of informational items that are used in large-scale information systems ranging from data values such as names and codes, to vocabularies, services and software components. The problem is that many of these registry-like services were designed with their own data models associated with the specific type of artifact they track. Additionally these services each have their own specific interface for interacting with the service. This Registry Service implements the data model specified in the ebXML Registry Information Model (RIM) specification that supports the various

  3. Applying Service-Orientation Through a Reference Architecture

    2008-02-01

    Full Text Available This article investigates the application of the service-oriented architectural style in the context of large organizations. It introduces an architectural reference framework that allows for a business process-centered development of composite applications. The framework groups artifacts of similar abstraction levels as well as concerns at five distinguished layers. This way, the service-oriented principles of abstraction and autonomy can be respected when designing applications. The layers also correspond to phases of a design methodology and cover the aspects of composite applications from process-centered orchestration, over transactional coordination to data transformation and connectivity. Based on the framework this article shows as well how an integration design methodology can be used to leverage the application systems in the context of a given business process.

    The Protein Identifier Cross-Reference (PICR) service is a tool that allows users to map protein identifiers, protein sequences and gene identifiers across over 100 different source databases. PICR takes input through an interactive website as well as Representational State Transfer (REST) and Simple Object Access Protocol (SOAP) services. It returns the results as HTML pages, XLS and CSV files. It has been in production since 2007 and has been recently enhanced to add new functionality and increase the number of databases it covers. Protein subsequences can be Basic Local Alignment Search Tool (BLAST) against the UniProt Knowledgebase (UniProtKB) to provide an entry point to the standard PICR mapping algorithm. In addition, gene identifiers from UniProtKB and Ensembl can now be submitted as input or mapped to as output from PICR. We have also implemented a 'best-guess' mapping algorithm for UniProt. In this article, we describe the usefulness of PICR, how these changes have been implemented, and the corresponding additions to the web services. Finally, we explain that the number of source databases covered by PICR has increased from the initial 73 to the current 102. New resources include several new species-specific Ensembl databases as well as the Ensembl Genome ones. PICR can be accessed at http://www.ebi.ac.uk/Tools/picr/.

    The Proteomics Standard Initiative Common QUery InterfaCe (PSICQUIC) specification was created by the Human Proteome Organization Proteomics Standards Initiative (HUPO-PSI) to enable computational access to molecular-interaction data resources by means of a standard Web Service and query language. Currently providing >150 million binary interaction evidences from 28 servers globally, the PSICQUIC interface allows the concurrent search of multiple molecular-interaction information resources using a single query. Here, we present an extension of the PSICQUIC specification (version 1.3), which has been released to be compliant with the enhanced standards in molecular interactions. The new release also includes a new reference implementation of the PSICQUIC server available to the data providers. It offers augmented web service capabilities and improves the user experience. PSICQUIC has been running for almost 5 years, with a user base growing from only 4 data providers to 28 (April 2013) allowing access to 151 310 109 binary interactions. The power of this web service is shown in PSICQUIC View web application, an example of how to simultaneously query, browse and download results from the different PSICQUIC servers. This application is free and open to all users with no login requirement (http://www.ebi.ac.uk/Tools/webservices/psicquic/view/main.xhtml).

    International Nuclear Information System (INIS)

    2005-01-01

    All comprehensive safeguards agreements between the IAEA and Member States concluded on the basis of INFCIRC/153 (Corrected) require the Member State to establish and maintain a system of accounting for and control of nuclear material subject to safeguards. In the years following the negotiation of INFCIRC/153, the IAEA's Secretariat and a large group of experts from Member States collaborated in the production of a set of guidelines to assist Member States in establishing their State system of accounting for and control of nuclear materials (SSAC). These guidelines, termed 'Guidelines for States' Systems of Accounting for and Control of Nuclear Materials', were published in 1980 as part of the IAEA's information series on the then developing safeguards system (IAEA/SG/INF/2). However, events over the past decade have changed the circumstances and requirements of the safeguards system. The IAEA, with support and assistance from Member States, embarked on an extensive multiyear effort to strengthen the safeguards system by increasing the IAEA's capability to detect undeclared nuclear material and activities. The centre-piece of this effort is the Model Protocol Additional to Safeguards Agreements (referred to as the 'additional protocol' and contained in INFCIRC/540 (Corrected)) approved by the Board of Governors in May 1997. The central components of strengthened safeguards and the additional protocol are increased access to information and increased physical access. The effective and efficient implementation of the strengthened safeguards system requires the SSACs to be effective and to cooperate closely with the IAEA. To achieve this aim the IAEA is, inter alia, revising IAEA/SG/INF/2, providing training and equipment to SSAC Authorities and providing an advisory service to Member States known as the IAEA SSAC Advisory Service (ISSAS). Accounting for and control of nuclear material is also key for nuclear security. General Conference resolutions (e.g. GC(48)/RES

Trends in chat reference services in medical school libraries were compiled from an exploration of medical school library Web sites and informal correspondence from medical school library personnel. Many medical libraries are actively investigating and planning new chat reference services, while others have decided not to pursue chat reference at this time. Anecdotal comments from medical school library staff provide insights into chat reference service.

    Reference service remains a core function of modern libraries. However, how and where we provide assistance has evolved with changing technologies and the shifting habits and preferences of our users. One way libraries can provide the on-demand, in-person assistance while managing and developing new services and resources that will benefit current and future users is to reconsider how their reference points and services are staffed and adopt a staff-based reference model. In Implementing an Inclusive Staffing Model for Today's Reference Services, Nims, Storm, and Stevens describe step-by-step

    2005-05-01

    The Stanford Solar Observatories Group and Haas Center for Public Service have created an innovative model for scientist-educator partnerships in which science students are trained and mentored by public service education professionals to create outreach events for local communities. The program, Science in Service, is part of the EPO plan for the Solar Group's participation in NASA's Solar Dynamics Observatory mission. Based on the principles of service learning, the Science in Service Program mentors college science students in best practices for communicating science and engages these students in public service projects that center on teaching solar science. The program goals are to - Enhance and expand the learning experiences that pre-college students, from underserved and underrepresented groups in particular, have in science and technology. - Promote leadership in community service in the area of science and engineering among the next generation of scientists and engineers, today's undergraduate students. - Encourage science and engineering faculty to think creatively about their outreach requirements and to create a community of faculty committed to quality outreach programs. This talk will describe the unique advantages and challenges of a research-public service partnership, explain the structure of Stanford's Science in Service Program, and present the experiences of the undergraduates and the outreach communities that have been involved in the program.

    2002-04-01

    Full Text Available Virtual reference - a service that allows librarians and patrons to communicate with each other in real time through the Internet by e-mail, chat or instant messaging - is currently a hot topic in libraries. In a way the commercial sector has challenged the reference function by offering Question & Answer services. To librarians this represents a threat and an opportunity. They can benefit from technologies and service models developed for the commercial arena by adapting these to virtual reference applications that will more effectively meet the needs of libraries on the Web. The literature provides many examples of pilots and experiments in taking reference into cyberspace. After an introduction to the in-and-outs of virtual reference, follows a short exposition of a virtual tour in the Netherlands where 7 of the 13 university libraries and the Royal Library have a basic ‚virtual helpdesk’. One thing is clear: virtual reference services are definitely put high on the agenda of the Dutch libraries. The Royal Library is one of the Dutch libraries, which is going to participate with QuestionPoint, formerly called Collaborative Digital Reference Service (CDRS, jointly developed by the Library of Congress and OCLC, which will provide web-based reference service to researchers anytime, anywhere, through an international, online network of member libraries.

    The reference materials (RMs) available for organic trace analysis (OTA) and the development programmes of the RM producers are reviewed. The need for a wider range of determinants, matrices and classes of RMs, particularly the more widespread use of laboratory RMs (LRMs) is discussed. Additional certified RMs should include phenolic surfactant degradation products, chlorophenolics from the wood and paper industries, and organobromines from fire retardants. RMs as molecular markers of geogenic, pyrogenic and biogenic sources; chlorophylls and xanthophylls as a measure of marine productivity and natural shellfish toxins are proposed.

    To determine the effect of reference-based pricing (RBP) on the percentage of lab services utilized by members that were at or below the reference price. Retrospective, quasi-experimental, matched, case-control pilot evaluation of an RBP benefit for lab services. The study group included employees of a multinational grocery chain covered by a national health insurance carrier and subject to RBP for lab services; it had access to an online lab shopping tool and was informed about the RBP benefit through employer communications. The reference group was covered by the same insurance carrier but not subject to RBP. The primary end point was lab compliance, defined as the percentage of lab claims with total charges at or below the reference price. Difference-in-difference regression estimation evaluated changes in lab compliance between the 2 groups. Higher compliance per lab claim was evident for the study group compared with the reference group (69% vs 57%; Ponline shopping tool was used by 7% of the matched-adjusted study group prior to obtaining lab services. Lab compliance was 76% for study group members using the online tool compared with 68% among nonusers who were subject to RBP (P<.01). RBP can promote cost-conscious selection of lab services. Access to facilities that offer services below the reference price and education about RBP improve compliance. Evaluation of the effect of RBP on higher-cost medical services, including radiology, outpatient specialty, and elective inpatient procedures, is needed.

    Kaiser, Alex; Williams, Samuel Webb; Madduri, Kamesh; Ibrahim, Khaled; Bailey, David H.; Demmel, James W.; Strohmaier, Erich

    2010-12-02

    For decades, computer scientists have sought guidance on how to evolve architectures, languages, and programming models in order to improve application performance, efficiency, and productivity. Unfortunately, without overarching advice about future directions in these areas, individual guidance is inferred from the existing software/hardware ecosystem, and each discipline often conducts their research independently assuming all other technologies remain fixed. In today's rapidly evolving world of on-chip parallelism, isolated and iterative improvements to performance may miss superior solutions in the same way gradient descent optimization techniques may get stuck in local minima. To combat this, we present TORCH: A Testbed for Optimization ResearCH. These computational reference kernels define the core problems of interest in scientific computing without mandating a specific language, algorithm, programming model, or implementation. To compliment the kernel (problem) definitions, we provide a set of algorithmically-expressed verification tests that can be used to verify a hardware/software co-designed solution produces an acceptable answer. Finally, to provide some illumination as to how researchers have implemented solutions to these problems in the past, we provide a set of reference implementations in C and MATLAB.

    In the history of astronomy, major advances in our understanding of the Universe have come from dramatic improvements in our ability to accurately measure astronomical quantities. Aided by rapid progress in information technology, current sky surveys are changing the way we view and study the Universe. Next-generation surveys will maintain this revolutionary progress. We focus here on the most ambitious survey currently planned in the visible band, the Large Synoptic Survey Telescope (LSST). LSST will have unique survey capability in the faint time domain. The LSST design is driven by four main science themes: constraining dark energy and dark matter, taking an inventory of the Solar System, exploring the transient optical sky, and mapping the Milky Way. It will be a large, wide-field ground-based system designed to obtain multiple images covering the sky that is visible from Cerro Pachon in Northern Chile. The current baseline design, with an 8.4 m (6.5 m effective) primary mirror, a 9.6 deg{sup 2} field of view, and a 3,200 Megapixel camera, will allow about 10,000 square degrees of sky to be covered using pairs of 15-second exposures in two photometric bands every three nights on average. The system is designed to yield high image quality, as well as superb astrometric and photometric accuracy. The survey area will include 30,000 deg{sup 2} with {delta} < +34.5{sup o}, and will be imaged multiple times in six bands, ugrizy, covering the wavelength range 320-1050 nm. About 90% of the observing time will be devoted to a deep-wide-fast survey mode which will observe a 20,000 deg{sup 2} region about 1000 times in the six bands during the anticipated 10 years of operation. These data will result in databases including 10 billion galaxies and a similar number of stars, and will serve the majority of science programs. The remaining 10% of the observing time will be allocated to special programs such as Very Deep and Very Fast time domain surveys. We describe how the

    ABSTRACT Core Facilities (CF) for advanced light microscopy (ALM) have become indispensable support units for research in the life sciences. Their organizational structure and technical characteristics are quite diverse, although the tasks they pursue and the services they offer are similar. Therefore, throughout Europe, scientists from ALM‐CFs are forming networks to promote interactions and discuss best practice models. Here, we present recommendations for ALM‐CF operations elaborated by the workgroups of the German network of ALM‐CFs, German Bio‐Imaging (GerBI). We address technical aspects of CF planning and instrument maintainance, give advice on the organization and management of an ALM‐CF, propose a scheme for the training of CF users, and provide an overview of current resources for image processing and analysis. Further, we elaborate on the new challenges and opportunities for professional development and careers created by CFs. While some information specifically refers to the German academic system, most of the content of this article is of general interest for CFs in the life sciences. Microsc. Res.

    Full Text Available Web search engines (WSE are powerful and popular tools in the field of information service management. This study is an attempt to examine the impact and usefulness of web search engines in providing virtual reference services (VRS within academic libraries in Pakistan. The study also attempts to investigate the relevant expertise and skills of library professionals in providing digital reference services (DRS efficiently using web search engines. Methodology used in this study is quantitative in nature. The data was collected from fifty public and private sector universities in Pakistan using a structured questionnaire. Microsoft Excel and SPSS were used for data analysis. The study concludes that web search engines are commonly used by librarians to help users (especially research scholars by providing digital reference services. The study also finds a positive correlation between use of web search engines and quality of digital reference services provided to library users. It is concluded that although search engines have increased the expectations of users and are really big competitors to a library’s reference desk, they are however not an alternative to reference service. Findings reveal that search engines pose numerous challenges for librarians and the study also attempts to bring together possible remedial measures. This study is useful for library professionals to understand the importance of search engines in providing VRS. The study also provides an intellectual comparison among different search engines, their capabilities, limitations, challenges and opportunities to provide VRS effectively in libraries.

    Full Text Available The digital age has brought major changes at the level of the reference services offered by libraries. The emergence of competition, represented by numerous organizations that also provide information services, has necessitated the reorganization of reference services so that they function according to the market laws. In this context marketing has become an essential tool for libraries. They must develop strategies to make sure that users will continue to ask for their services. The number of those attracted to online information services is growing and many traditional users of libraries may be encountered at present in virtual environments where the possibilities for communication and interaction, for sharing information and generating knowledge are clearly better. Many libraries have already taken the step towards the virtual world and offer now assistance and information services in environments such as Second Life where there are possible both games and educational activities.

  19. Enabling Data Intensive Science through Service Oriented Science: Virtual Laboratories and Science Gateways

    2014-12-01

    We present collaborative work on a generic, modular infrastructure for virtual laboratories (VLs, similar to science gateways) that combine online access to data, scientific code, and computing resources as services that support multiple data intensive scientific computing needs across a wide range of science disciplines. We are leveraging access to 10+ PB of earth science data on Lustre filesystems at Australia's National Computational Infrastructure (NCI) Research Data Storage Infrastructure (RDSI) node, co-located with NCI's 1.2 PFlop Raijin supercomputer and a 3000 CPU core research cloud. The development, maintenance and sustainability of VLs is best accomplished through modularisation and standardisation of interfaces between components. Our approach has been to break up tightly-coupled, specialised application packages into modules, with identified best techniques and algorithms repackaged either as data services or scientific tools that are accessible across domains. The data services can be used to manipulate, visualise and transform multiple data types whilst the scientific tools can be used in concert with multiple scientific codes. We are currently designing a scalable generic infrastructure that will handle scientific code as modularised services and thereby enable the rapid/easy deployment of new codes or versions of codes. The goal is to build open source libraries/collections of scientific tools, scripts and modelling codes that can be combined in specially designed deployments. Additional services in development include: provenance, publication of results, monitoring, workflow tools, etc. The generic VL infrastructure will be hosted at NCI, but can access alternative computing infrastructures (i.e., public/private cloud, HPC).The Virtual Geophysics Laboratory (VGL) was developed as a pilot project to demonstrate the underlying technology. This base is now being redesigned and generalised to develop a Virtual Hazards Impact and Risk Laboratory

    The National Oceanic and Atmospheric Administration's National Geophysical Data Center (NGDC) World Data Center for Geophysics and Marine Geology provides scientific stewardship, products and services for geophysical data, including bathymetry, gravity, magnetics, seismic reflection, data derived from sediment and rock samples, as well as historical natural hazards data (tsunamis, earthquakes, and volcanoes). Although NGDC has long made many of its datasets available through map and other web services, it has now developed a second generation of services to improve the discovery and access to data. These new services use off-the-shelf commercial and open source software, and take advantage of modern JavaScript and web application frameworks. Services are accessible using both RESTful and SOAP queries as well as Open Geospatial Consortium (OGC) standard protocols such as WMS, WFS, WCS, and KML. These new map services (implemented using ESRI ArcGIS Server) are finer-grained than their predecessors, feature improved cartography, and offer dramatic speed improvements through the use of map caches. Using standards-based interfaces allows customers to incorporate the services without having to coordinate with the provider. Providing fine-grained services increases flexibility for customers building custom applications. The Integrated Ocean and Coastal Mapping program and Coastal and Marine Spatial Planning program are two examples of national initiatives that require common data inventories from multiple sources and benefit from these modern data services. NGDC is also consuming its own services, providing a set of new browser-based mapping applications which allow the user to quickly visualize and search for data. One example is a new interactive mapping application to search and display information about historical natural hazards. NGDC continues to increase the amount of its data holdings that are accessible and is augmenting the capabilities with modern web

    Citations to scholarly items are building bricks for multidisciplinary science communication. Citation analyses are currently influencing individual career advancement and ranking of academic and research institutions worldwide. This article overviews the involvement of scientific authors, reviewers, editors, publishers, indexers, and learned associations in the citing and referencing to preserve the integrity of science communication. Authors are responsible for thorough bibliographic searches to select relevant references for their articles, comprehend main points, and cite them in an ethical way. Reviewers and editors may perform additional searches and recommend missing essential references. Publishers, in turn, are in a position to instruct their authors over the citations and references, provide tools for validation of references, and open access to bibliographies. Publicly available reference lists bear important information about the novelty and relatedness of the scholarly items with the published literature. Few editorial associations have dealt with the issue of citations and properly managed references. As a prime example, the International Committee of Medical Journal Editors (ICMJE) issued in December 2014 an updated set of recommendations on the need for citing primary literature and avoiding unethical references, which are applicable to the global scientific community. With the exponential growth of literature and related references, it is critically important to define functions of all stakeholders of science communication in curbing the issue of irrational and unethical citations and thereby improve the quality and indexability of scholarly journals.

    In the scope of this study, pre-service science teachers (PSST) developed and carried out science demonstrations with everyday materials for elementary school students as a community service activity. 17 PSST enrolled in the community services practices course at Kocaeli University comprised the sample of the present study. Community service practices aim to develop consciousness of social responsibility and professional skills, as well as to gain awareness of social and community problems and find solutions for pre-service teachers. With this aim, each PSST developed five science demonstration activities and their brochures during a semester. At the end of the semester, a total of 85 demonstrations were carried out at public elementary schools, which are especially located in socioeconomically poor districts of Kocaeli, Turkey. In the present case study, the effect of developing and carrying out science demonstrations for elementary school students on six of the PSST' teaching practices on density and buoyancy concept was investigated. 30-minute interviews conducted with each PSST, videos recorded during their demonstration performances, brochures they prepared for their demonstration activities, and reflection papers were used as data collection tools of the study. The results showed that community service practices with science demonstrations had positive effects on PSST' science content knowledge and pedagogical content knowledge.

    The maturation of web services standards and technologies sets the stage for a distributed "Service-Oriented Architecture" (SOA) for NASA's next generation science data processing. This architecture will allow members of the scientific community to create and combine persistent distributed data processing services and make them available to other users over the Internet. NASA has initiated a project to create a suite of specialized data mining web services designed specifically for science data. The project leverages the Algorithm Development and Mining (ADaM) toolkit as its basis. The ADaM toolkit is a robust, mature and freely available science data mining toolkit that is being used by several research organizations and educational institutions worldwide. These mining services will give the scientific community a powerful and versatile data mining capability that can be used to create higher order products such as thematic maps from current and future NASA satellite data records with methods that are not currently available. The package of mining and related services are being developed using Web Services standards so that community-based measurement processing systems can access and interoperate with them. These standards-based services allow users different options for utilizing them, from direct remote invocation by a client application to deployment of a Business Process Execution Language (BPEL) solutions package where a complex data mining workflow is exposed to others as a single service. The ability to deploy and operate these services at a data archive allows the data mining algorithms to be run where the data are stored, a more efficient scenario than moving large amounts of data over the network. This will be demonstrated in a scenario in which a user uses a remote Web-Service-enabled clustering algorithm to create cloud masks from satellite imagery at the Goddard Earth Sciences Data and Information Services Center (GES DISC).

    Full Text Available This study aims to reveal personal beliefs of prospective science teachers about assessment. The study involved 46 prospective science teachers who have passed the 7th semester the course evaluation. Personal beliefs of prospective science teachers about assessment revealed using Personal Beliefs about Assessment Scale (SKDA. SKDA developed based on standards of assessment literacy and construct validity is done using Rasch models, with a Cronbach Alpha value of 0.93. Analysis and classification level of personal beliefs of prospective science teacher about assessment is done using the Rasch model is based on the logit ability of prospective science teachers based on the separation. The results showed that personal beliefs of prospective science teachers about assessment varies between two or three levels, depending on the standard of assessment literacy. There are still some aspects of the assessment of each standard that is trusted or considered less important by prospective teachers of science, namely: 1 consider the learning targets, learning experiences, and learning decision in choosing methods of assessment; 2 using the existing assessment and available in developing assessment methods; 3 interpret summary score; 4 use the assessment results to decision-making about the school and curriculum development; 5 consider extracurricular activities when developing procedures for judging; 6 report the result to another level with appropriate means and methods; and 7 to know when the assessment results are used inappropriately/inappropriate by others.

    Ecosystem services are at a crossroad. The natural capital needed to produce them is diminishing (Millennium Ecosystem Assessment, 2005). At the same time, the science relating to their identification, production, and valuation is advancing. Examples of ecosystem services applications are abundant in the literature. In addition, the concept of ecosystem services and its applications are attracting attention and are becoming more visible. The concept of ecosystem services, however, is still not routinely applied to many natural resource management decisions.

Reference & User Services Quarterly, 45(1, 65-75. Retrieved from https://www.jstor.org/journal/refuseserq Abstract Objective - To assess the quality of service provided by reference staff in public libraries when presented with a request for LGBTQ information by a young person. Design - Unobtrusive observation without informed consent. Setting - Public library branches in the greater Vancouver area, British Columbia, Canada. Subjects - Reference librarians. Methods - A 19-year-old posing as a high school student approached reference desk staff at 20 public library branches. The student proxy, “Angela”, was instructed to ask for books on forming a gay-straight alliance at her school and, if there was a full reference interview, to also ask for recommendations of novels that the group might read. She recorded the reactions, both verbal and nonverbal, using Reference and User Services Association guidelines as a template. Library administrators were aware of the potential visits and permitted the research, but the reference desk staff were not aware of a potential visit by the student proxy. The researcher claimed that her method, while deceptive, was necessary to obtain authentic reactions from the library staff. Main Results - Most reference librarians approached by Angela made adequate attempts to assist her, although a few library staff reacted negatively to her query. Half of the librarians reacted positively to the patron’s request, with most of the others providing neutral responses. Very few of the librarians actually taught the patron how to use the library’s catalog to search for materials, and most of the librarians were unable to find appropriate materials due to not knowing the appropriate search terms. Only three library staff showed overt disapproval of the search topic, such as frowning or rushing

    Asmus, J. F.

    In fields such as studio art, art conservation, archaeology, anthropology, music, and architecture it is often understood that many of the advances emerge from the introduction of new developments from science and technology. Scientific research is often justified on the basis of its past as well as potential future fallout into other endeavors as diverse as medicine, manufacturing, and the humanities. The diffusion of scientific innovation into the practice of art conservation has been punctuated by the introduction of a series of diverse technologies. Trace element and isotopic analyses, infrared imaging, ultraviolet fluorescence inspection, advanced coatings and adhesives, scanning electron microscopy, and photon/electron microprobes are notable examples. For the past thirty years various laser technologies have demonstrated utility in the practice of art conservation, as well. These include photon cleaning and divestment, holographic display and nondestructive analysis, surface characterization through laser fluorescence, radiation scattering and absorption, as well as laser-induced ultrasound. At the dawn of laser technology's introduction into the art conservation field (1972-74) the Center for Art/Science Studies (CASS) was established at the University of California, San Diego (UCSD) with the hope of accelerating and broadening the diffusion of scientific developments into art conservation practice. Surprisingly, one of the first events in the CASS/UCSD transpired when a Visual Arts Department student employed a primitive laser statue cleaner to "correct" a silk-screen print. In the course of maintaining her laser this art student discovered a dramatically improved method for aligning the complex optical beam train by utilizing her artistic training. A few months later another CASS/UCSD student in the Photographic Arts Program (while modifying a ruby laser to experiment with theater-lighting special effects) discovered an improved laser beam

  11. A philosophical examination of Mead's pragmatist constructivism as a referent for adult science education

    Science.gov (United States)

    Furbish, Dean Russel

    The purpose of this study is to examine pragmatist constructivism as a science education referent for adult learners. Specifically, this study seeks to determine whether George Herbert Mead's doctrine, which conflates pragmatist learning theory and philosophy of natural science, might facilitate (a) scientific concept acquisition, (b) learning scientific methods, and (c) preparation of learners for careers in science and science-related areas. A philosophical examination of Mead's doctrine in light of these three criteria has determined that pragmatist constructivism is not a viable science education referent for adult learners. Mead's pragmatist constructivism does not portray scientific knowledge or scientific methods as they are understood by practicing scientists themselves, that is, according to scientific realism. Thus, employment of pragmatist constructivism does not adequately prepare future practitioners for careers in science-related areas. Mead's metaphysics does not allow him to commit to the existence of the unobservable objects of science such as molecular cellulose or mosquito-borne malarial parasites. Mead's anti-realist metaphysics also affects his conception of scientific methods. Because Mead does not commit existentially to the unobservable objects of realist science, Mead's science does not seek to determine what causal role if any the hypothetical objects that scientists routinely posit while theorizing might play in observable phenomena. Instead, constructivist pragmatism promotes subjective epistemology and instrumental methods. The implication for learning science is that students are encouraged to derive scientific concepts based on a combination of personal experience and personal meaningfulness. Contrary to pragmatist constructivism, however, scientific concepts do not arise inductively from subjective experience driven by personal interests. The broader implication of this study for adult education is that the philosophically laden

    2012-01-01

    To evaluate participant and referring care provider satisfaction associated with a spinal triage assessment service delivered by physiotherapists in collaboration with orthopedic surgeons. People with low back-related complaints were recruited from those referred to a spinal triage assessment program delivered by physiotherapists. Measures of patient and provider satisfaction were completed at approximately 4 weeks after the assessment. The satisfaction surveys were analyzed quantitatively with descriptive statistics and qualitatively with an inductive thematic approach of open and axial coding. A total of 108/115 participants completed the posttest satisfaction survey. Sixty-six percent of participants were "very satisfied" with the service and 55% were "very satisfied" with the recommendations that were made. Only 18% of referring care providers completed the satisfaction survey and 90.5% of those were "very satisfied" with the recommendations. Sixty-one participants and 14 care providers provided comments which revealed a diverse range of themes which were coded into positive (ie, understanding the problem, communication, customer service, efficiency, and management direction), negative (ie, lack of detail, time to follow-up, cost) and neutral related to the triage service, and an "other" category unrelated to the service (ie, chronic symptoms, comorbidities, and limited access to health care.) The quantitative results of the participant survey demonstrated very high levels of satisfaction with the service and slightly less satisfaction with the recommendations that were made. Satisfaction of referring care providers with the recommendations and report was also high, but given the low response rate, these results should be interpreted with caution. Qualitative analysis of participant and provider comments revealed a diverse range of themes. These other issues may be important contextual factors that have the potential to impact patient relevant outcomes.

  19. Science in the service of energy

    CERN Multimedia

    2013-01-01

    Meetings on the subject of energy have marked the past two weeks at CERN. The first was on how we use energy, the second on how we might generate it in the future. Both are important, not just for CERN, but for society as a whole.   Let’s take a look at the first of those gatherings. It was the second in a series of workshops on energy for sustainable science, organised by CERN in collaboration with the European Spallation Source (ESS), which hosted the first, and ERF, the European association of national research facilities. The way we use energy is increasingly important, and constitutes a substantial fraction of CERN's operating budget. We consume 1.2 TeraWatt-hours (TWh) of energy per year. To put that in to context, the canton of Geneva consumes 3TWh per year. It is therefore incumbent on a laboratory like CERN to ensure that we use energy in the most efficient, responsible and sustainable way possible. Since the first workshop in 2011, much progress has been made in te...

  20. Connecting Students and Policymakers through Science and Service-Learning

    Szymanski, D. W.

    2017-12-01

    Successful collaborations in community science require the participation of non-scientists as advocates for the use of science in addressing complex problems. This is especially true, but particularly difficult, with respect to the wicked problems of sustainability. The complicated, unsolvable, and inherently political nature of challenges like climate change can provoke cynicism and apathy about the use of science. While science education is a critical part of preparing all students to address wicked problems, it is not sufficient. Non-scientists must also learn how to advocate for the role of science in policy solutions. Fortunately, the transdisciplinary nature of sustainability provides a venue for engaging all undergraduates in community science, regardless of major. I describe a model for involving non-science majors in a form of service-learning, where the pursuit of community science becomes a powerful pedagogical tool for civic engagement. Bentley University is one of the few stand-alone business schools in the United States and provides an ideal venue to test this model, given that 95% of Bentley's 4000 undergraduates major in a business discipline. The technology-focused business program is combined with an integrated arts & sciences curriculum and experiential learning opportunities though the nationally recognized Bentley Service-Learning and Civic Engagement Center. In addition to a required general education core that includes the natural sciences, students may opt to complete a second major in liberal studies with thematic concentrations like Earth, Environment, and Global Sustainability. In the course Science in Environmental Policy, students may apply to complete a service-learning project for an additional course credit. The smaller group of students then act as consultants, conducting research for a non-profit organization in the Washington, D.C. area involved in geoscience policy. At the end of the semester, students travel to D.C. and present

    The Space Station, projected for construction in the early 1990s, will be an orbiting, low-gravity, permanently manned facility providing unprecedented opportunities for scientific research. Facilities for Life Sciences research will include a pressurized research laboratory, attached payloads, and platforms which will allow investigators to perform experiments in the crucial areas of Space Medicine, Space Biology, Exobiology, Biospherics and Controlled Ecological Life Support System (CELSS). These studies are designed to determine the consequences of long-term exposure to space conditions, with particular emphasis on assuring the permanent presence of humans in space. The applied and basic research to be performed, using humans, animals, and plants, will increase our understanding of the effects of the space environment on basic life processes. Facilities being planned for remote observations from platforms and attached payloads of biologically important elements and compounds in space and on other planets (Exobiology) will permit exploration of the relationship between the evolution of life and the universe. Space-based, global scale observations of terrestrial biology (Biospherics) will provide data critical for understanding and ultimately managing changes in the Earth's ecosystem. The life sciences community is encouraged to participate in the research potential the Space Station facilities will make possible. This document provides the range and scope of typical life sciences experiments which could be performed within a pressurized laboratory module on Space Station.

    This work constitutes a argued analysis of the publication of the article of Hertoghe et al. "Anti aging medicine, a science based, essential medicine " whose full and unreviewed publication was forced in the framework of the Belgian law on the right of reply to an earlier publication entitled " Anti-Aging Medicine: Science or Marketing? ". We confirm the absence of scientific evidence on the effectiveness of hormonal treatments used in this approach by highlighting the different techniques allowing doctors who promote this approach to make believe in their effectiveness. This is clearly to mix in one sentence established truths and unproven facts, use references inappropriately especially by misappropriation of studies on groups of patients with hormone deficiency in order to justify treatment in healthy subjects, to ignore recent references undermining ancient literature, to betray the authors' conclusions. Our critical analysis is also considering compliance with the guidelines for integrity in scientific publications.

    We developed a standardized cost estimation method for occupational health (OH) services. The purpose of this study was to set reference OH services costs and to conduct OH services cost management assessments in two workplaces by comparing actual OH services costs with the reference costs. Data were obtained from retrospective analyses of OH services costs regarding 15 OH activities over a 1-year period in three manufacturing workplaces. We set the reference OH services costs in one of the three locations and compared OH services costs of each of the two other workplaces with the reference costs. The total reference OH services cost was 176,654 Japanese yen (JPY) per employee. The personnel cost for OH staff to conduct OH services was JPY 47,993, and the personnel cost for non-OH staff was JPY 38,699. The personnel cost for receipt of OH services-opportunity cost-was JPY 19,747, expense was JPY 25,512, depreciation expense was 34,849, and outsourcing cost was JPY 9,854. We compared actual OH services costs from two workplaces (the total OH services costs were JPY 182,151 and JPY 238,023) with the reference costs according to OH activity. The actual costs were different from the reference costs, especially in the case of personnel cost for non-OH staff, expense, and depreciation expense. Using our cost estimation tool, it is helpful to compare actual OH services cost data with reference cost data. The outcomes help employers make informed decisions regarding investment in OH services.

    Full Text Available The study described the teaching methods used by pre-service teachers in Science. It focused on the strategies, techniques, materials, innovative methods and pattern of teaching science used by the pre-service teachers as described in their lesson plans. The qualitative and quantitative design was used in the study. The books, teacher hand-outs from classroom lectures were the sources of methods, strategies and techniques. The chalkboard and self-made drawings and charts were the materials often used. Conventional methods like lecture, open class discussion and demonstration were commonly employed. The strategies included group discussion, use of motivating questions and stories to arouse the interest of students. The direct eye contact, body expressions, jokes and news/trivia were frequent techniques. Integration of values in the lesson became less as the year level increases. The pattern of teaching drawn followed the formal style: I Objectives, II Subject matter, III Learning Tasks, IV Synthesis of the lesson, V Assessment and VI Enrichment. The conventional method and pattern of teaching by the pre-service teachers of PSU suggest that students in the College of Teacher Education should be trained to be more innovative and open in trying out more advanced teaching methods. Furthermore, PSU science pre-service teachers should use methods which can develop higher order thinking skills among high school students.

    International Nuclear Information System (INIS)

    Sharpe, P.H.G.; Sephton, J.P.

    1999-01-01

    In this paper we describe the work that has been carried out at National Physical Laboratory (NPL) to develop a mailed alanine reference dosimetry service for radiotherapy dose levels. The service is based on alanine/paraffin wax dosimeters produced at NPL. Using a data analysis technique based on spectrum fitting, it has been possible to achieve a precision of dose measurement better than ±0.05 Gy (1σ). A phantom set has been developed for use in high energy photon beams, which enables simultaneous irradiation of alanine dosimeters and ionisation chambers in a well defined geometry. Studies in photon beams of energies between 60 Co and 20 MeV have shown no significant energy dependence (<1%) for alanine relative to dose determination using a graphite calorimeter. Work is underway to extend the service to electron beams, and preliminary results are presented on the direct calibration of alanine in electron beams using a graphite calorimeter. (author)

    To investigate (1) the prevalence of language deficits and disorders and (2) the relationship of bilingual language skills and psychopathology, in Spanish-English bilingual children referred for child and adolescent psychiatry services. Bilingual language skills, emotional/behavioral problems, sociodemographics, immigration variables, and nonverbal IQ were studied in 50 consecutively referred children. Estimated prevalence was high for language deficits (48%) and disorders (41%), with most cases (>79%) being of the mixed receptive-expressive type. In children with clinically significant emotional/behavioral problems, bilingual language skills were strongly and inversely correlated with problem scores, particularly global problems (r = -0.67, p or = -0.54; p language disorders and delays and (2) the close tie between poor language skills and emotional/behavioral problems. The data strongly suggest the clinical importance and feasibility of language assessment and the significance of receptive problems in bilingual children referred for psychiatric services. A safe approach is to fully assess language skills, rather than misattributing these children's language delays to normal bilingual acquisition processes.

    2016-05-01

    Full Text Available The Internet of Things and Services (IoTS has encouraged the development of service provisioning systems in respect to Smart City topics. Most of them are operated as heterogeneous systems which limits end customers’ access and contradicts with IoTS principles. In this paper, we discuss and develop a reference model of an interconnected service marketplace ecosystem. The prototypical implementation incorporates findings from an empirical study and lessons learned from research projects. The elaborated ecosystem enables service request roaming between different parties across system boundaries. The paper presents a feasible centralized architecture, introduces involved parties and parts of a developed message protocol. Why a contracting mechanism is indispensable for request roaming is also outlined. The model’s feasibility is demonstrated by means of a current electric mobility use case: providing access to foreign charging infrastructure without multiple registrations. This work contributes to simplify the data exchange between service platforms to improve Smart City solutions and to support travelers with intelligent mobility applications.

    2017-03-27

    The rising prevalence of chronic diseases is pressing health systems to introduce reforms. Primary healthcare and multidisciplinary models have been suggested as approaches to deal with this challenge, with new roles for nurses and pharmacists being advocated. More recently, implementing healthcare based on information systems and technologies (e.g. eHealth) has been proposed as a way to improve health services. However, implementing online pharmaceutical services, including their adoption by pharmacists and patients, is still an open research question. In this paper we present ePharmacare, a new online pharmaceutical service implemented using Design Science Research. The Design Science Research Methodology (DSRM) was chosen to implement this online service for chronic diseases management. In the paper, DSRM's different activities are explained, from the definition of the problem to the evaluation of the artifact. During the design and development activities, surveys, observations, focus groups, and eye-tracking glasses were used to validate pharmacists' and patients' requirements. During the demonstration and evaluation activities the new service was used with real-world pharmacists and patients. The results show the contribution of DSRM in the implementation of online services for pharmacies. We found that pharmacists spend only 50% of their time interacting with patients, uncovering a clear opportunity to implement online pharmaceutical care services. On the other hand, patients that regularly visit the same pharmacy recognize the value in patient follow-up demanding to use channels such as the Internet for their pharmacy interactions. Limitations were identified regarding the high workload of pharmacists, but particularly their lack of know-how and experience in dealing with information systems (IST) for the provision of pharmaceutical services. This paper summarizes a research project in which an online pharmaceutical service was proposed, designed, developed

    The role of Earth science data centers has traditionally been to maintain central archives that serve openly available Earth observation data. However, in order to ensure data are as useful as possible to a diverse user community, Earth science data centers must move beyond simply serving as an archive to offering innovative data services to user communities. A virtual collection, the end product of a curation activity that searches, selects, and synthesizes diffuse data and information resources around a specific topic or event, is a data curation service that improves the discoverability, accessibility, and usability of Earth science data and also supports the needs of unanticipated users. Virtual collections minimize the amount of the time and effort needed to begin research by maximizing certainty of reward and by providing a trustworthy source of data for unanticipated users. This presentation will define a virtual collection in the context of an Earth science data center and will highlight a virtual collection case study created at the Global Hydrology Resource Center data center.

    The authors developed a software-based realtime IPTV monitoring system based on Reduced Reference framework, and evaluated the proposed system. One of the quality issues of the IPTV service is the picture quality degradation caused by packet loss. The proposed system precisely estimates the PSNR of the corrupted received picture by extracting and comparing image features from transmission and receiver side. Computer simulations show that PSNR estimation with a 0.945 correlation coefficient at a data channel bitrate of 36kbps is possible using the proposed system.

    Purpose: To describe the methodology and experience of the Secondary Laboratory of Dosimetric Calibration of Cuba in the establishment of the TLD Postal Service for quality audits of beams of Co-60 in reference conditions. Materials and methods: Through the Coordinated Project of Research (Contract 10794) its was bought 200 solid thermoluminescent detectors of LiF: Mg, Ti (TLD-100) in micro bars form with dimensions of 6 x 1 x 1 mm and of the JR 1152F type manufactured in China. All these detectors were identified individually with a serial number on one of its faces, using a graphite fine sheet. Those detectors for its irradiation are introduced in cylindrical plastic capsules developed and used by the International Atomic Energy Agency (IAEA) in the Audit Postal Service of Dose IAEA/WHO, the capsules have one cavity equal to 3 mm for that is necessary to recover this cavity with a fine plastic tube so that the detectors remain immobile during the irradiation. The method used to determine the individual sensitivity of the thermoluminescent detectors is: to irradiate a detectors group (100 micro bars) 4 times in those same geometric conditions, with the same irradiation history and reading, then it is determine for each detector a sensitivity factor equal to the average of those readings obtained for the 4 irradiation cycles for each i detector among the average of all the reading values obtained during the 4 cycles. The thermoluminescent signal is obtained with a Harshaw 2000C/B reader manual. Results: The satisfactory results obtained in the verification of the calibration of the TLD system, using the reference irradiation service of the Seibersdorf Dosimetry Laboratory of the IAEA in three different years are shown. The results of the audits carried out to the different radiotherapy services of the country in different years are also presented. Conclusions: The experience with the detectors acquired in the project demonstrates that with an appropriate

    To know the cutoff point at which in-house Nuclear Medicine Department (MND) customers consider that the quality of service is good (personalized cutoff). We conducted a survey of the professionals who had requested at least 5 tests to the Nuclear Medicine Department. A total of 71 doctors responded (response rate: 30%). A question was added to the questionnaire for the user to establish a cutoff point for which they would consider the quality of service as good. The quality non-conformities, areas of improvement and strong points of the six questions measuring the quality of service (Likert scale 0 to 10) were compared with two different thresholds: personalized cutoff and one proposed by the service itself a priori. Test statistics: binomial and Student's t-test for paired data. A cutoff value of 7 was proposed by the service as a reference while 68.1% of respondents suggested a cutoff above 7 points (mean 7.9 points). The 6 elements of perceived quality were considered strong points with the cutoff proposed by the MND, while there were 3 detected with the personalized threshold. Thirteen percent of the answers were nonconformities with the service cutoff versus 19.2% with the personalized one, the differences being statistically significant (difference 95% CI 6.44%:0,83-12.06). The final image of the perceived quality of an in-house customer is different when using the cutoff established by the Department versus the personalized cutoff given by the respondent.

    The Origins Space Telescope (OST) is the mission concept for the Far-Infrared Surveyor, one of the four science and technology definition studies of NASA Headquarters for the 2020 Astronomy and Astrophysics Decadal survey. The science case for OST covers four themes: Tracing the Signature of Life and the Ingredients of Habitable Worlds; Charting the Rise of Metals, Dust and the First Galaxies, Unraveling the Co-evolution of Black Holes and Galaxies and Understanding Our Solar System in the Context of Planetary System Formation. Using a set of proposed observing programs from the community, we estimate a design reference mission for OST mission concept 1. The mission will complete significant programs in these four themes and have time for other programs from the community. Origins will enable flagship-quality general observing programs led by the astronomical community in the 2030s. We welcome you to contact the Science and Technology Definition Team (STDT) with your science needs and ideas by emailing us at ost_info@lists.ipac.caltech.edu.

    2016-06-01

    The Plastic Surgery In-Service Training Exam is a knowledge assessment tool widely used during plastic surgery training in the United States. This study analyzed literature supporting correct answer choices to determine highest yield sources, journal publication lag, and journal impact factors. Digital syllabi of 10 consecutive Plastic Surgery In-Service Training Exam administrations (2006 to 2015) were reviewed. The most-referenced articles, journals, and textbooks were determined. Mean journal impact factor and publication lag were calculated and differences were elucidated by section. Two thousand questions and 5386 references were analyzed. From 2006 to 2015, the percentage of journal citations increased, whereas textbook references decreased (p < 0.001). Plastic and Reconstructive Surgery was cited with greatest frequency (38.5 percent), followed by Clinics in Plastic Surgery (5.6 percent), Journal of Hand Surgery (American volume) (5.1 percent), and Annals of Plastic Surgery (3.8 percent). There was a trend toward less publication lag over the study period (p = 0.05), with a mean publication lag of 9.1 ± 9.0 years for all journal articles. Mean journal impact factor was 2.3 ± 4.3 and lowest for the hand and lower extremity section (1.7 ± 2.8; p < 0.001). The highest yield textbooks were elucidated by section. Plastic surgery faculty and residents may use these data to facilitate knowledge acquisition during residency.

    The identification of families at-risk for hereditary cancer is extremely important due to the prevention potential in those families. However, the number of Brazilian genetic services providing oncogenetic care is extremely low for the continental dimension of the country and its population. Therefore, at-risk patients do not receive appropriate assistance. This report describes the creation, structure and management of a cancer genetics service in a reference center for cancer prevention and treatment, the Barretos Cancer Hospital (BCH). The Oncogenetics Department (OD) of BCH offers, free of charge, to all patients/relatives with clinical criteria, the possibility to perform i) genetic counseling, ii) preventive examinations and iii) genetic testing with the best quality standards. The OD has a multidisciplinary team and is integrated with all specialties. The genetic counseling process consists (mostly) of two visits. In 2014, 614 individuals (371 families) were seen by the OD. To date, over 800 families were referred by the OD for genetic testing. The support provided by the Oncogenetics team is crucial to identify at-risk individuals and to develop preventive and personalized behaviors for each situation, not only to the upper-middle class population, but also to the people whose only possibility is the public health system.

  11. WDS Trusted Data Services in Support of International Science

    2014-12-01

    Today's research is international, transdisciplinary, and data-enabled, which requires scrupulous data stewardship, full and open access to data, and efficient collaboration and coordination. New expectations on researchers based on policies from governments and funders to share data fully, openly, and in a timely manner present significant challenges but are also opportunities to improve the quality and efficiency of research and its accountability to society. Researchers should be able to archive and disseminate data as required by many institutions or funders, and civil society to scrutinize datasets underlying public policies. Thus, the trustworthiness of data services must be verifiable. In addition, the need to integrate large and complex datasets across disciplines and domains with variable levels of maturity calls for greater coordination to achieve sufficient interoperability and sustainability. The World Data System (WDS) of the International Council for Science (ICSU) promotes long-term stewardship of, and universal and equitable access to, quality-assured scientific data and services across a range of disciplines in the natural and social sciences. WDS aims at coordinating and supporting trusted scientific data services for the provision, use, and preservation of relevant datasets to facilitate scientific research, in particular under the ICSU umbrella, while strengthening their links with the research community. WDS certifies it Members, holders and providers of data or data products, using internationally recognized standards. Thus, providing the building blocks of a searchable common infrastructure, from which a data system that is both interoperable and distributed can be formed. This presentation will describe the coordination role of WDS and more specifically activities developed by its Scientific Committee to: Improve and stimulate basic level Certification for Scientific Data Services, in particular through collaboration with the Data Seal of

    Full Text Available We report on attempts to put an astronomical database – the Sloan Digital Sky Survey science archive – in the cloud. We find that it is very frustrating to impossible at this time to migrate a complex SQL Server database into current cloud service offerings such as Amazon (EC2 and Microsoft (SQL Azure. Certainly it is impossible to migrate a large database in excess of a TB, but even with (much smaller databases, the limitations of cloud services make it very difficult to migrate the data to the cloud without making changes to the schema and settings that would degrade performance and/or make the data unusable. Preliminary performance comparisons show a large performance discrepancy with the Amazon cloud version of the SDSS database. These difficulties suggest that much work and coordination needs to occur between cloud service providers and their potential clients before science databases – not just large ones but even smaller databases that make extensive use of advanced database features for performance and usability – can successfully and effectively be deployed in the cloud. We describe a powerful new computational instrument that we are developing in the interim – the Data-Scope – that will enable fast and efficient analysis of the largest (petabyte scale scientific datasets.

    Undertaking of a complete audit of the service of mammography, as recommended by BI-RADS(®), in a private reference institution for breast cancer diagnosis in the city of São Paulo, SP, Brazil, and comparison of results with those recommended by the literature. Retrospective, analytical and cross-sectional study including 8,000 patients submitted to mammography in the period between April 2010 and March 2011, whose results were subjected to an internal audit. The patients were followed-up until December 2012. The radiological classification of 7,249 screening mammograms, according to BI-RADS, was the following: category 0 (1.43%), 1 (7.82%), 2 (80.76%), 3 (8.35%), 4 (1.46%), 5 (0.15%) and 6 (0.03%). The breast cancer detection ratio was 4.8 cases per 1,000 mammograms. Ductal carcinoma in situ was found in 22.8% of cases. Positive predictive values for categories 3, 4 and 5 were 1.3%, 41.3% and 100%, respectively. In the present study, the sensitivity of the method was 97.1% and specificity, 97.4%. The complete internal audit of a service of mammography is essential to evaluate the quality of such service, which reflects on an early breast cancer detection and reduction of mortality rates.

    The study population were all librarians working in the Reference Services, information and Public services in Libraries of Ferdowsi University of Mashhad (32 person. Interviews were conducted with one of the administrative staff at the Central Library. The checklist was completed with the help of the head of each library. The findings showed that about 35% of reference librarians using less electronic reference services. in this field, Others evaluate themselves as moderate. And all the librarians (100 percent were mentioned that offer of electronic reference services is necessary. Meanwhile, only 28% believed that librarians have the Technology skills and nearly 50% believe that they have the searching skills. In this regard, more than 60% of librarians said they have suitable skills. Based on the finding and the gap between present and ideal situation it seems that the usage rate of technology in its ideal form has the deepest gap and with the librarian's individual skills has not it.

    Technical advances in mobile devices such as smartphones and tablets have produced an extraordinary increase in their use around the world and have become part of our daily lives. The possibility of carrying these devices in a pocket, particularly mobile phones, has enabled ubiquitous access to Internet resources. Furthermore, in the life sciences world there has been a vast proliferation of data types and services that finish as Web Services. This suggests the need for research into mobile clients to deal with life sciences applications for effective usage and exploitation. Analysing the current features in existing bioinformatics applications managing Web Services, we have devised, implemented, and deployed an easy-to-use web-based lightweight mobile client. This client is able to browse, select, compose parameters, invoke, and monitor the execution of Web Services stored in catalogues or central repositories. The client is also able to deal with huge amounts of data between external storage mounts. In addition, we also present a validation use case, which illustrates the usage of the application while executing, monitoring, and exploring the results of a registered workflow. The software its available in the Apple Store and Android Market and the source code is publicly available in Github. Mobile devices are becoming increasingly important in the scientific world due to their strong potential impact on scientific applications. Bioinformatics should not fall behind this trend. We present an original software client that deals with the intrinsic limitations of such devices and propose different guidelines to provide location-independent access to computational resources in bioinformatics and biomedicine. Its modular design makes it easily expandable with the inclusion of new repositories, tools, types of visualization, etc.

    a variety of services to support women to undertake weight management behaviours during pregnancy have recently been implemented as a means to reduce the risks to mother and infant. In the UK, midwives lead the care of the majority of pregnant women and are seen as the ideal source of referral into antenatal services. However, midwives have reported concerns regarding raising the topic of weight with obese women and negative referral experiences have been cited as a reason not to engage with a service. This study explored midwives' experiences of referring women to one of two antenatal weight management services. qualitative, cross-sectional interview and focus group study, with data analysed thematically. midwifery teams in the West Midlands, England. midwives responsible for referring to either a home-based, one to one service (N=12), or a community-based, group service (N=11). four themes emerged from the data. Participants generally had a positive View of the service, but their Information needs were not fully met, as they wanted more detail about the service and feedback regarding the women they had referred. Approaches to referral differed, with some participants referring all women who met the eligibility criteria, and some offering women a choice to be referred or not. Occasionally the topic was not raised at all when a negative reception was anticipated. Reasons for poor uptake of the services included pragmatic barriers, and their perception of women's lack of interest in weight management. midwives' differing views on choice and gaining agreement to refer means referral practices vary, which could increase the risk that obese women have inequitable access to weight management services. However, midwives' confidence in the services on offer may be increased with more detailed information about the service and feedback on referrals, which would additionally act as prompts to refer. weight management services need to improve communication with their

  18. Cognitive dissonance of science and religion in pre-service elementary school teachers

    Science.gov (United States)

    Malloy, Robert Earl, Sr.

    Throughout history science and religion have been in conflict. Many of the theories of science do not agree with the religious beliefs of pre-service teachers. Those teachers who will be teaching in the science classroom, must be able to present science without prejudice of personal religious beliefs. Are pre-service teachers prepared for science/religion conflicts? How much conflict do pre-service teachers have between science and religion? This study suggests that pre-service teachers may have a high degree of conflict between science and religion, and that they have received no educational experience on how to deal with this conflict. Such conflict poses a potential problem when presenting science in the classroom, in that non-science information may not be separated from the science presented.

    Fajardo-Ortiz, Guillermo; Ortiz-Montalvo, Armando

    2013-01-01

    Historically, health services administration has been managed under a Taylorist, Fayolist, humanist and bureaucratic focus approach. However, today dynamic and competitive behaviors that require others approaches in management are developing. Because of the social, scientific and technological changes that are occurring, it is necessary to abandon hierarchical and authoritarian schemes, "up and down" lines, prescriptive rules and order line up must be left behind. Health services administration is an adapted complex system that is not proportional, neither predictable in direction or magnitude. A new proposal is to focus on the sciences of complexity, where the social factors, materials, economics, human and ethics coincide with order and disorder, reason and unreason, and in which we must accept that the phenomenon that emerges creates different organizing different structures from the addition or subtraction of components. There is distance in the process of cause and direct effect. The mirage from the sciences of complexity are trans-disciplinary and we have accepted this in others branches of knowledge, such as quantum physics, non-linear mathematics and cybernetics, so we have to accept the influence of entropy, non-entropy, attractors, the theory of chaos and fractals.

    1977-07-01

    A study to determine the impact that the Area Health Education Center type of programs may have on health science libraries was conducted by the Extramural Programs, National Library of Medicine, in conjunction with a contract awarded by the Bureau of Health Manpower, Health Resources Administration, to develop an inventory of the AHEC type of projects in the United States. Specific study tasks included a review of these programs as they relate to library and information activities, on-site surveys on the programs to define their needs for library services and information, and a categorization of library activities. A major finding was that health science libraries and information services are generally not included in AHEC program planning and development, although information and information exchange is a fundamental part of the AHEC type of programs. This study suggests that library inadequacies are basically the result of this planning failure and of a lack of financial resources; however, many other factors may be contributory. The design and value of library activities for these programs needs explication.

    Several factors, which include prenatal diagnosis and availability of new therapeutic procedures, have contributed to change the profile of patients with congenital heart disease (CHD). Knowing these changes is important to a better health care. Description of profile of patients with CHD in a reference service in the State of Rio Grande do Sul, Brazil. It is a cross-sectional study including 684 patients with CHD in a service of pediatric cardiology from January 2007 to May 2008. We interviewed the patients (and/or their parents) and examined these patients (congenital malformations, anthropometric measures). Moreover, their charts were reviewed in order to detail heart diseases, procedures and echocardiography. Patients were from 16 days to 66 years old, 51.8% were female, and 93.7% were Caucasian. The mean age at diagnosis was 15.8 +/- 46.8 months. Ventricular septal defect, patent ductus arteriosus and Tetralogy of Fallot were the most prevalent CHD. 59.1% of examined patients, whose average age was 44.3 +/- 71.2 months, have been undergoing therapeutic procedures; 30.4% had congenital extracardiac malformations; and 12 patients had genetic syndrome. Regarding development, 46.6% had low weight and height gain, and 13.7% had neuropsychomotor delay. Furthermore, 18.4% had family history of congenital heart disease. Neuropsychomotor delay and low weight and height gain may be related to CHD. Establishing a profile of patients with CHD, who were treated at an institution of reference, may function as a basis in which health care of this population can be planed appropriately.

    Body weight and body composition are relevant to the outcomes of cancer and antineoplastic therapy. However, their role in Phase I clinical trial patients is unknown. We reviewed symptom burden, body composition, and survival in 104 patients with advanced cancer referred to a Phase I oncology service. Symptom burden was analyzed using the MD Anderson Symptom Assessment Inventory(MDASI); body composition was evaluated utilizing computerized tomography(CT) images. A body mass index (BMI)≥25 kg/m² was considered overweight. Sarcopenia, severe muscle depletion, was assessed using CT-based criteria. Most patients were overweight (n = 65, 63%); 53 patients were sarcopenic (51%), including 79% of patients with a BMIbody composition: 215 (71-358) (BMIcancer diagnosis predicted longer survival in multivariate analysis after controlling for age, gender, performance status, and fat index. Patients referred to a Phase I clinic had a high frequency of sarcopenia and a BMI≥25 kg/m², independent of symptom burden. Body composition variables were predictive of clinically relevant survival differences, which is potentially important in developing Phase I studies.

    Background: Cancer is a major public health problem. Early diagnosis and treatment are essential for reducing mortality. This study aimed to analyze factors associated with delay in breast cancer diagnosis and treatment among women attending a reference cancer service. Methods: This retrospective, cross-sectional study was performed with data collected from medical records and interviews conducted with women diagnosed with breast cancer and treated from October 2013 to October 2014 at a cancer reference hospital in Paraná, Southern Brazil. Results: A total of 82 participants were enrolled during the study period; their average age was 58.2 ± 11.5 years. The average time taken for final diagnosis of breast cancer was 102.5 ± 165.5 days. Treatment onset was delayed in the majority of cases, and the average time elapsing from diagnostic biopsy to onset of primary treatment was 72.3 ± 54.0 days. The odds of treatment delay were higher among the women with a low educational level. Conclusions: The results underline the need for proposals aimed at early detection, identification of risk factors and timely provision of treatment by health managers that focus on this group.

    Despite the professional and academic relevance of the Brazilian oral pathology diagnostic laboratories, no information about their usage profile is available in the English literature. The objective of the present study is to report data about the histopathological and immunohistochemical exams performed in a Brazilian regional reference laboratory of oral pathology, as well as its main users. Information about all histopathological exams performed between 2002 and 2012 was retrieved from the files of the Oral and Maxillofacial Pathology Service of the School of Dentistry of Universidade Federal de Minas Gerais. Data collected included: 1) requestor of exam; 2) diagnosis classification; and 3) immunohistochemical tests. Descriptive statistical analyses were done. 13,522 histopathological exams were performed, mean 1,229/year. The Public Health System of the city of Belo Horizonte was the main requestor of exams (77.13%), followed by private professionals (19.26%), and other cities (2.03%). Most lesions were considered benign (12,599/ 93.17%), with 854 malignant lesions (6.32%). 469 immunohistochemical tests were performed; 324 (69.08%) were from benign diagnosis, and 145 (30.92%) from malignant diagnosis. The most used antibodies were against S100, vimentin, smooth muscle actin, actin muscle specific HHF-35, and pan-cytokeratin AE1/AE3. Public Health System is the major user of the diagnostic service on oral pathology in our institution. Most diagnoses were of benign lesions, although many malignant lesions were detected. Immunohistochemistry was particularly important in solving challenging cases.

    The NASA Goddard Earth Sciences Data and Information Services Center (GES DISC), in addition to serving the Earth Science community as one of the major Distributed Active Archive Centers (DAACs), provides much more than just data. Among the value-added services available to general users are subsetting data spatially and/or by parameter, online analysis (to avoid downloading unnecessary all the data), and assistance in obtaining data from other centers. Services available to data producers and high-volume users include consulting on building new products with standard formats and metadata and construction of data management systems. A particularly useful service is data processing at the DISC (i.e., close to the input data) with the users' algorithms. This can take a number of different forms: as a configuration-managed algorithm within the main processing stream; as a stand-alone program next to the on-line data storage; as build-it-yourself code within the Near-Archive Data Mining (NADM) system; or as an on-the-fly analysis with simple algorithms embedded into the web-based tools. Partnerships between the GES DISC and scientists, both producers and users, allow the scientists concentrate on science, while the GES DISC handles the of data management, e.g., formats, integration and data processing. The existing data management infrastructure at the GES DISC supports a wide spectrum of options: from simple data support to sophisticated on-line analysis tools, producing economies of scale and rapid time-to-deploy. At the same time, such partnerships allow the GES DISC to serve the user community more efficiently and to better prioritize on-line holdings. Several examples of successful partnerships are described in the presentation.

    Kutluca, A. Y.; Aydın, A.

    2017-08-01

    The study explored the changes in pre-service science teachers' understanding of the nature of science and their opinions about the nature of science, science teaching and argumentation after their participation in explicit nature of science (NOS) and socioscientific argumentation processes. The participants were 56 third-grade pre-service science teachers studying in a state university in Turkey. The treatment group comprised 27 participants, and there were 29 participants in the comparison group. The comparison group participants were involved in a student-centred science-teaching process, and the participants of the treatment group were involved in explicit NOS and socioscientific argumentation processes. In the study, which lasted a total of 11 weeks, a NOS-as-argumentation questionnaire was administered to all the participants to determine their understanding of NOS at the beginning and end of the data collection process, and six random participants of the treatment group participated in semi-structured interview questions in order to further understand their views regarding NOS, science teaching and argumentation. Qualitative and quantitative data analysis revealed that the explicit NOS and socioscientific argumentation processes had a significant effect on pre-service science teachers' NOS understandings. Furthermore, NOS, argumentation and science teaching views of the participants in the treatment group showed a positive change. The results of this study are discussed in light of the related literature, and suggestions are made within the context of contribution to science-teaching literature, improvement of education quality and education of pre-service teachers.

    Full Text Available Body weight and body composition are relevant to the outcomes of cancer and antineoplastic therapy. However, their role in Phase I clinical trial patients is unknown.We reviewed symptom burden, body composition, and survival in 104 patients with advanced cancer referred to a Phase I oncology service. Symptom burden was analyzed using the MD Anderson Symptom Assessment Inventory(MDASI; body composition was evaluated utilizing computerized tomography(CT images. A body mass index (BMI≥25 kg/m² was considered overweight. Sarcopenia, severe muscle depletion, was assessed using CT-based criteria.Most patients were overweight (n = 65, 63%; 53 patients were sarcopenic (51%, including 79% of patients with a BMI<25 kg/m² and 34% of those with BMI≥25 kg/m². Sarcopenic patients were older and less frequently African-American. Symptom burden did not differ among patients classified according to BMI and presence of sarcopenia. Median (95% confidence interval survival (days varied according to body composition: 215 (71-358 (BMI<25 kg/m²; sarcopenic, 271 (99-443 (BMI<25 kg/m²; non-sarcopenic, 484 (286-681 (BMI≥25 kg/m²; sarcopenic; 501 d (309-693 (BMI≥25 kg/m²; non-sarcopenic. Higher muscle index and gastrointestinal cancer diagnosis predicted longer survival in multivariate analysis after controlling for age, gender, performance status, and fat index.Patients referred to a Phase I clinic had a high frequency of sarcopenia and a BMI≥25 kg/m², independent of symptom burden. Body composition variables were predictive of clinically relevant survival differences, which is potentially important in developing Phase I studies.

    Limb-body wall defect is a rare condition characterized by a combination of large and complex defects of the ventral thorax and abdominal wall with craniofacial and limb anomalies. The aim of this study was to describe the experience of our fetal medicine service, a reference from Southern Brazil, with prenatally diagnosed patients with a limb-body wall defect in a 3 years period. Only patients who fulfilled the criteria suggested by Hunter et al. (2011) were included in the study. Clinical data and results of radiological and cytogenetic evaluation were collected from their medical records. Our sample was composed of 8 patients. Many of their mothers were younger than 25 years (50%) and in their first pregnancy (62.5%). It is noteworthy that one patient was referred due to suspected anencephaly and another due to a twin pregnancy with an embryonic sac. Craniofacial defects were verified in three patients (37.5%), thoracic/abdominal abnormalities in 6 (75%) and limb defects in eight (100%). Congenital heart defects were observed in five patients (62.5%). One of them presented a previously undescribed complex heart defect. The results disclosed that complementary exams, such as MRI and echocardiography, are important to better define the observed defects. Some of them, such as congenital heart defects, may be more common than previously reported. This definition is essential for the proper management of the pregnancy and genetic counseling of the family. The birth of these children must be planned with caution and for the prognosis a long survival possibility, despite unlikely and rare, must be considered. © 2014 Wiley Periodicals, Inc.

    Interest in sharing interdisciplinary environmental modeling results and related data is increasing among scientists. The U.S. Geological Survey Geo Data Portal project enables data sharing by assembling open-standard Web services into an integrated data retrieval and analysis Web application design methodology that streamlines time-consuming and resource-intensive data management tasks. Data-serving Web services allow Web-based processing services to access Internet-available data sources. The Web processing services developed for the project create commonly needed derivatives of data in numerous formats. Coordinate reference system manipulation and spatial statistics calculation components implemented for the Web processing services were confirmed using ArcGIS 9.3.1, a geographic information science software package. Outcomes of the Geo Data Portal project support the rapid development of user interfaces for accessing and manipulating environmental data.

    2008-01-01

    This report presents the methodology and experience of the Cuban's Secondary Standard Dosimetry Laboratory for the implementation of postal dose quality audits service for Co-60 beams in reference conditions, using TLDs. Under coordinated research project (Contract 10794) were bought (TLD -100) Tl rods type JR 1152F made in China, with dimensions of 6 mm x 1 mm x 1 mm. All of these rods were identified individually with a consecutive number made over one of its sides, using a fine tip of graphite. The method used to determinate the individual sensibility of the TL detectors was: irradiating a group of them, with the same history of irradiation and readout (100 rods approximately), four serial times in the same geometrical conditions, to read them out and to attribute to each of them a sensitivity factor. This sensitivity factor is equal to average for the 4 cycle of irradiation and readout of the quote between the TL readout from dosimeter i and the mean of all values for each cycle. The TLD signal was read using HARSHAW 2000C/B reader. The results obtained in the external verification of the accuracy of the dose determination by the TLD system were performed in cooperation with IAEA Dosimetry Laboratory at Seibersdorf in different years are shown, the results obtained of the quality audits carried out to the different services of radiotherapy of the country are analysed also. The quality audits are an useful tool for the improvement of the accuracy in the dosimetry of clinical beams of radiotherapy with Co-60, contributing this way to the improvement of the life quality to cancer patients of the Cuban system of health.

    Zachert, M J

    1987-07-01

    The periodical literature on group instructional services in health sciences libraries was analyzed to determine the nature of these services, their target audiences, and their institutional settings. Three kinds of reports were identified: descriptions of services (70%), reviews of the literature (10.5%), and future-oriented articles that advocate various group instructional services (19.5%). Five target audiences were identified: library users, staff, librarian peers, library science students, and patients. Instructional services were offered primarily in medical school/center libraries, hospital libraries, and the National Library of Medicine and its Regional Medical Libraries (RMLs). To a lesser extent, health sciences educational services are offered through other professional school libraries, library associations and consortia, and schools of library science. There are gaps in the literature in the areas of library experience with marketing, evaluation, administration of the offered educational services, and continuing education for health sciences librarians.

    2017-01-01

    In an effort to ensure that data in NASA's Earth Observing System Data and Information System (EOSDIS) is available to a wide variety of users through the tools of their choice, NASA continues to focus on exposing data and services using standards based protocols. Specifically, this work has focused recently on the Web Coverage Service (WCS). Experience has been gained in data delivery via GetCoverage requests, starting out with WCS v1.1.1. The pros and cons of both the version itself and different implementation approaches will be shared during this session. Additionally, due to limitations with WCS v1.1.1 ability to work with NASA's Earth science data, this session will also discuss the benefit of migrating to WCS 2.0.1 with EO-x to enrich this capability to meet a wide range of anticipated user's needs This will enable subsetting and various types of data transformations to be performed on a variety of EOS data sets.

  16. Impact of Chinese Culture on Pre-service Science Teachers' Views of the Nature of Science

    Wan, Dongsheng; Zhang, Hongshia; Wei, Bing

    2018-04-01

    This study examines Chinese pre-service teachers' (N = 30) views on the nature of science (NOS) and how Chinese culture influences their views. Participants were from two teachers' universities in eastern China. As an exploratory and interpretive study, a scenario-based interview approach was adopted. The results indicated that the participants held unique views about the five key aspects of NOS. Many participants have alternative and contemporary views of NOS, but few possess classical views. In fact, teachers adopted features of the Confucian Doctrine of the Mean either consciously or unconsciously to account for their views of NOS. This research reflects that the Doctrine of the Mean affected Chinese teachers' views of NOS, making them rather deficient in their understandings of classical NOS. Based on empirical data, it is argued that science teacher training in China should focus on the content and objectives of classical NOS, rather than just teaching contemporary views of NOS. Taking Chinese culture into consideration, science teacher education in China cannot entirely import the strategies of teaching the classical views of NOS from the developed world, but should develop, design and contextualize local strategies that are suitable for the training of Chinese science teachers. Some issues for further investigation of learners' views of NOS in non-Western contexts are suggested as implications from this study.

    To investigate the prevalence of and factors associated with performance of annual mammography by women above 40 years of age. This cross-sectional retrospective study was conducted at an oncology reference service in Southern Brazil from October 2013 to October 2014 with 525 women aged 40 years or older. The prevalence of annual mammography was 54.1%; annual mammographic screening was performed for women without private medical insurance, who were under hormone replacement therapy and who had used contraception in the past. An association was found between non-performance of breast clinical and self-examination and non-performance of mammographic screening. Use of mammography for breast cancer screening in the public health care setting proved to be accessible; nevertheless, the proportion of screened women was low, and they exhibited poor adherence to the basic measures of care recommended for breast assessment. Thus, control of breast cancer requires implementing actions targeting the population most vulnerable to non-adherence to screening in addition to continuously monitoring and assessing that population to reduce the prevalence of this disease.

  18. Birth order and sibling sex ratio of children and adolescents referred to a gender identity service.

    Directory of Open Access Journals (Sweden)

    Doug P Vanderlaan

    Full Text Available In adult male samples, homosexuality is associated with a preponderance of older brothers (i.e., the fraternal birth order effect. In several studies comparing gender dysphoric youth, who are likely to be homosexual in adulthood, to clinical or non-clinical control groups, the findings have been consistent with the fraternal birth order effect in males; however, less is known about unique sibship characteristics of gender dysphoric females. The current study investigated birth order and sibling sex ratio in a large sample of children and adolescents referred to the same Gender Identity Service (N = 768. Probands were classified as heterosexual males, homosexual males, or homosexual females based on clinical diagnostic information. Groups differed significantly in age and sibship size, and homosexual females were significantly more likely to be only children. Subsequent analyses controlled for age and for sibship size. Compared to heterosexual males, homosexual males had a significant preponderance of older brothers and homosexual females had a significant preponderance of older sisters. Similarly, the older sibling sex ratio of homosexual males showed a significant excess of brothers whereas that of homosexual females showed a significant excess of sisters. Like previous studies of gender dysphoric youth and adults, these findings were consistent with the fraternal birth order effect. In addition, the greater frequency of only children and elevated numbers of older sisters among the homosexual female group adds to a small literature on sibship characteristics of potential relevance to the development of gender identity and sexual orientation in females.

In addition, the greater frequency of only children and elevated numbers of older sisters among the homosexual female group adds to a small literature on sibship characteristics of potential relevance to the development of gender identity and sexual orientation in females.

  1. Science, Neutrality and Objectivity in Nuclear Research: Shared References or Ideal Types?

    International Nuclear Information System (INIS)

    Bovy, Michel; Laes, Erik; Eggermont, Gilbert

    2003-01-01

    Science, neutrality and objectivity in nuclear research are shared references because they can be considered as useful ideal types to support the communication process. This doesn't mean these references are empty, or have no effects on the organizational level. But the expert needs to recognize which type of justification he's ready to share with others (should it be peers or other social actors) because he has to share two types of communication process. The closure is less in the object than in the acceptance of a shared ideal world justification. While the expert uses the methodology of science to focus on the relevancy of some means, the layman requires being part of their communication process before the black box is closed, not becoming a scientist himself. The gap can be reduced by a combined effort to open up the communication process to each other based on a justification principle that cannot be mastered in advance by one side. This clearly show us democracy is not a question only debated in the governmental spheres but also in new kind of Parliaments allowing exchanges and open discussions removed from some pre-determined roles play. This requires time and sufficient room of manoeuvre from both sides. For example, it means interactions conditioned by the urgent necessity to make acceptable some technical depository solution for nuclear waste build some communication walls in terms of justification. The whole design process of society sometimes is at stake because of some inherited justification principles making science, independence and neutrality responsible for our welfare and safety. A solution could consist of using this framework in the beginning of the process and not in an attempt to stop controversies when results are needed (as a depository for nuclear waste). Another one could consist of enlarging the actor-network to more actors bringing more justification principles and varied interests. This won't be seen as a search for more order but a

    A training program was developed for enhancing pre-service science teachers' pedagogical content knowledge (PCK). The pre-service science teachers are able to: understand science curriculum, knowledge of assessment in science, knowledge of students' understanding of science, instructional strategies and orientations towards science teaching, which is conceptualized as PCK [5]. This study examined the preservice science teachers' understandings and their practices which include five pre-service science teachers' PCK. In this study, the participants demonstrated their PCK through the process of the training program by writing content representations (CoRes), preparing the lesson plans, micro-teaching, and actual teaching respectively. All pre-service science teachers' performs were collected by classroom observations. Then, they were interviewed. The results showed that the pre-service science teachers progressively developed knowledge components of PCK. Micro-teaching is the key activities for developing PCK. However, they had some difficulties in their classroom teaching. They required of sufficient ability to design appropriate instructional strategies and assessment activities for teaching. Blending content and pedagogy is also a matter of great concern. The implication of this study was that science educators can enhance pre-service science teachers' PCK by fostering their better understandings of the instructional strategies, assessment activities and blending between content and pedagogy in their classroom.

    Fujiwara, Toyofumi; Yamamoto, Yasunori

    2015-01-01

    To promote research activities in a particular research area, it is important to efficiently identify current research trends, advances, and issues in that area. Although review papers in the research area can suffice for this purpose in general, researchers are not necessarily able to obtain these papers from research aspects of their interests at the time they are required. Therefore, the utilization of the citation contexts of papers in a research area has been considered as another approach. However, there are few search services to retrieve citation contexts in the life sciences domain; furthermore, efficiently obtaining citation contexts is becoming difficult due to the large volume and rapid growth of life sciences papers. Here, we introduce the Colil (Comments on Literature in Literature) database to store citation contexts in the life sciences domain. By using the Resource Description Framework (RDF) and a newly compiled vocabulary, we built the Colil database and made it available through the SPARQL endpoint. In addition, we developed a web-based search service called Colil that searches for a cited paper in the Colil database and then returns a list of citation contexts for it along with papers relevant to it based on co-citations. The citation contexts in the Colil database were extracted from full-text papers of the PubMed Central Open Access Subset (PMC-OAS), which includes 545,147 papers indexed in PubMed. These papers are distributed across 3,171 journals and cite 5,136,741 unique papers that correspond to approximately 25 % of total PubMed entries. By utilizing Colil, researchers can easily refer to a set of citation contexts and relevant papers based on co-citations for a target paper. Colil helps researchers to comprehend life sciences papers in a research area more efficiently and makes their biological research more efficient.

    2014-12-01

    Full Text Available Modern 3D geovisualization systems (3DGeoVSs are complex and evolving systems that are required to be adaptable and leverage distributed resources, including massive geodata. This article focuses on 3DGeoVSs built based on the principles of service-oriented architectures, standards and image-based representations (SSI to address practically relevant challenges and potentials. Such systems facilitate resource sharing and agile and efficient system construction and change in an interoperable manner, while exploiting images as efficient, decoupled and interoperable representations. The software architecture of a 3DGeoVS and its underlying visualization model have strong effects on the system’s quality attributes and support various system life cycle activities. This article contributes a software reference architecture (SRA for 3DGeoVSs based on SSI that can be used to design, describe and analyze concrete software architectures with the intended primary benefit of an increase in effectiveness and efficiency in such activities. The SRA integrates existing, proven technology and novel contributions in a unique manner. As the foundation for the SRA, we propose the generalized visualization pipeline model that generalizes and overcomes expressiveness limitations of the prevalent visualization pipeline model. To facilitate exploiting image-based representations (IReps, the SRA integrates approaches for the representation, provisioning and styling of and interaction with IReps. Five applications of the SRA provide proofs of concept for the general applicability and utility of the SRA. A qualitative evaluation indicates the overall suitability of the SRA, its applications and the general approach of building 3DGeoVSs based on SSI.

    Full Text Available Objective – To study source citing practice in telephone reference service in large public libraries in the United States and Canada. Design – Field simulation (unobtrusive testing.Setting – Large public libraries in the United States and Canada.Subjects – Telephone reference staff of the 25 largest public libraries in the United States and Canada.Methods – The 2005 World Book Almanac was used to select the 25 largest (in terms of population served public libraries in Canada and the United States. Each system’s Web site was checked to locate the telephone number for reference service. For some systems it was necessary to call the general telephone number for the main library or the first branch listed on the Web site. Five ready reference test questions were developed from a list of questions that students in a graduate library and information science course had previously asked of public library telephone reference services. The selected questions in the order that they were asked were: 1. Can you tell me when Valentine’s Day is?2. Who is the current governor/premier (of the state/province where the library is located?3. What is the population of Montana?4. In which state is the Southern Poverty Law Center (SPLC located?5. What is the French word for “chiropractor”?The authors called each of the 25 libraries during five consecutive weeks at different times of the business day. Each week, one question was asked; once an answer was received, no clarification was requested and the call was ended. The study reports the results of 125 reference transactions. For this study, the following definitions were used to assess complete citation for each type of information resource:• For a Web site – the complete URL (title and sponsor of the site not required.• For a digital database – the database title and the title and year of the specific item (author, publisher, page number not required.• For a print resource – the title

    With continuous progress on scientific research, a large amount of datasets has been and will be produced. The data access and sharing along with their storage and homogenization within a unique and coherent framework is a new challenge for the whole scientific community. This is particularly emphasized for geo-scientific laboratories, encompassing the most diverse Earth Science disciplines and typology of data. To this aim the "Multiscale Laboratories" Work Package (WP16), operating in the framework of the European Plate Observing System (EPOS), is developing a virtual platform of geo-scientific data and services for the worldwide community of laboratories. This long-term project aims at merging the top class multidisciplinary laboratories in Geoscience into a coherent and collaborative network, facilitating the standardization of virtual access to data, data products and software. This will help our community to evolve beyond the stage in which most of data produced by the different laboratories are available only within the related scholarly publications (often as print-version only) or they remain unpublished and inaccessible on local devices. The EPOS multi-scale laboratory platform will provide the possibility to easily share and discover data by means of open access, DOI-referenced, online data publication including long-term storage, managing and curation services and to set up a cohesive community of laboratories. The WP16 is starting with three pilot cases laboratories: (1) rock physics, (2) palaeomagnetic, and (3) analogue modelling. As a proof of concept, first analogue modelling datasets have been published via GFZ Data Services (http://doidb.wdc-terra.org/search/public/ui?&sort=updated+desc&q=epos). The datasets include rock analogue material properties (e.g. friction data, rheology data, SEM imagery), as well as supplementary figures, images and movies from experiments on tectonic processes.

  8. Caring Enough to Teach Science. Helping Pre-service Teachers View Science Instruction as an Ethical Responsibility

    Science.gov (United States)

    Grinell, Smith; Rabin, Colette

    2017-11-01

    The goal of this project was to motivate pre-service elementary teachers to commit to spending significant instructional time on science in their future classrooms despite their self-assessed lack of confidence about teaching science and other impediments (e.g., high-stakes testing practices that value other subjects over science). Pre-service teachers in science methods courses explored connections between science and ethics, specifically around issues of ecological sustainability, and grappled with their ethical responsibilities as teachers to provide science instruction. Survey responses, student "quick-writes," interview transcripts, and field notes were analyzed. Findings suggest that helping pre-service teachers see these connections may shape their beliefs and dispositions in ways that may motivate them to embark on the long road toward improving their science pedagogical content knowledge and ultimately to teach science to their students more often and better than they otherwise might. The approach may also offer a way for teachers to attend to the moral work of teaching.

  9. Semantic Data Access Services at NASA's Atmospheric Science Data Center

    Science.gov (United States)

    Huffer, E.; Hertz, J.; Kusterer, J.

    2012-12-01

    The corpus of Earth Science data products at the Atmospheric Science Data Center at NASA's Langley Research Center comprises a widely heterogeneous set of products, even among those whose subject matter is very similar. Two distinct data products may both contain data on the same parameter, for instance, solar irradiance; but the instruments used, and the circumstances under which the data were collected and processed, may differ significantly. Understanding the differences is critical to using the data effectively. Data distribution services must be able to provide prospective users with enough information to allow them to meaningfully compare and evaluate the data products offered. Semantic technologies - ontologies, triple stores, reasoners, linked data - offer functionality for addressing this issue. Ontologies can provide robust, high-fidelity domain models that serve as common schema for discovering, evaluating, comparing and integrating data from disparate products. Reasoning engines and triple stores can leverage ontologies to support intelligent search applications that allow users to discover, query, retrieve, and easily reformat data from a broad spectrum of sources. We argue that because of the extremely complex nature of scientific data, data distribution systems should wholeheartedly embrace semantic technologies in order to make their data accessible to a broad array of prospective end users, and to ensure that the data they provide will be clearly understood and used appropriately by consumers. Toward this end, we propose a distribution system in which formal ontological models that accurately and comprehensively represent the ASDC's data domain, and fully leverage the expressivity and inferential capabilities of first order logic, are used to generate graph-based representations of the relevant relationships among data sets, observational systems, metadata files, and geospatial, temporal and scientific parameters to help prospective data consumers

    Full Text Available Abstract Background The complexity and inter-related nature of biological data poses a difficult challenge for data and tool integration. There has been a proliferation of interoperability standards and projects over the past decade, none of which has been widely adopted by the bioinformatics community. Recent attempts have focused on the use of semantics to assist integration, and Semantic Web technologies are being welcomed by this community. Description SADI - Semantic Automated Discovery and Integration - is a lightweight set of fully standards-compliant Semantic Web service design patterns that simplify the publication of services of the type commonly found in bioinformatics and other scientific domains. Using Semantic Web technologies at every level of the Web services "stack", SADI services consume and produce instances of OWL Classes following a small number of very straightforward best-practices. In addition, we provide codebases that support these best-practices, and plug-in tools to popular developer and client software that dramatically simplify deployment of services by providers, and the discovery and utilization of those services by their consumers. Conclusions SADI Services are fully compliant with, and utilize only foundational Web standards; are simple to create and maintain for service providers; and can be discovered and utilized in a very intuitive way by biologist end-users. In addition, the SADI design patterns significantly improve the ability of software to automatically discover appropriate services based on user-needs, and automatically chain these into complex analytical workflows. We show that, when resources are exposed through SADI, data compliant with a given ontological model can be automatically gathered, or generated, from these distributed, non-coordinating resources - a behaviour we have not observed in any other Semantic system. Finally, we show that, using SADI, data dynamically generated from Web services

    Boiling is a two-phase heat transfer process where large heat fluxes can be transferred with small driving temperature differences. The high performance of boiling makes the process very interesting for heat transfer applications and it is widely used in industry for example in power plants, refrigeration systems, and electronics cooling. Nevertheless, due to the large number of involved phenomena and their often highly dynamic nature a fundamental understanding and closed theoretical description is not yet accomplished. The design of systems incorporating the process is generally based on empirical correlations, which are commonly accompanied by large uncertainties and, thus, has to be verified by expensive test campaigns. Hence, strong efforts are currently made to develop applicable numerical tools for a reliable prediction of the boiling heat transfer performance and limits. In order to support and validate this development and, in particular as a precondition, to enhance the basic knowledge about boiling the comprehensive multi-scale experiment RUBI (Reference mUlti-scale Boiling Investigation) for the Fluid Science Laboratory on board the ISS is currently in preparation. The scientific objectives and requirements of RUBI have been defined by the members of the ESA topical team "Boiling and Multiphase Flow" and addresses fundamental aspects of boiling phenomena. The main objectives are the measurement of wall temperature and heat flux distribution underneath vapour bubbles with high spatial and tem-poral resolution by means of IR thermography accompanied by the synchronized high-speed observation of the bubble shapes. Furthermore, the fluid temperature in the vicinity and inside of the bubbles will be measured by a micro sensor array. Additional stimuli are the generation of an electric field above the heating surface and a shear flow created by a forced convection loop. The objective of these stimuli is to impose forces on the bubbles and investigate the

    This study is a follow-up to one published in computer science education in 2010 that reported preliminary results showing a positive impact of service learning on student attitudes associated with success and retention in computer science. That paper described how service learning was incorporated into a computer science course in the context of the Students & Technology in Academia, Research, and Service (STARS) Alliance, an NSF-supported broadening participation in computing initiative that aims to diversify the computer science pipeline through innovative pedagogy and inter-institutional partnerships. The current paper describes how the STARS Alliance has expanded to diverse institutions, all using service learning as a vehicle for broadening participation in computing and enhancing attitudes and behaviors associated with student success. Results supported the STARS model of service learning for enhancing computing efficacy and computing commitment and for providing diverse students with many personal and professional development benefits.

  20. Science education with the help of media. Educating science concerning the help of current news of media referring to it

    International Nuclear Information System (INIS)

    Lazar, I.; Agoston, L.

    2005-01-01

    In the last decades, at the beginning of the 21st century high school students turn their back on science more frequently than before, therefore the generation of the community of reliable scientists and experts becomes the elder. The time spent studying science in schools is also decreasing. However, mass-communication, electronic and traditional media plays more and more part in the description and explanation of scientific problems in our time. Media is inundated with questions, facts and rumours in connection with science, therefore imaginary fears, beliefs and superstitions can get into the limelight of interests. Problems like keeping people frightened with radioactivity and the ionizing and non-ionizing radiations is probably the most popular way of making ''bad news'' (panic) in the mass-media, and they particularly call our attention to the most current tasks in education of the next generations. In order to help to keep the public informed in a precise and exact way, it's necessary to put natural science into practice in high schools. Our new method of science education could prove the necessity of science taught through the current news of the media. This means students learn by making discussions and corrections of the news. The Science and Media Project provides the possibility of applying scientific ways of thinking about questions of our environment and life and it also improves critical approach towards new information. This method is put to practice by real project works, including a lot of fieldwork and reading of papers and scientific literature, enabling the students to discover and solve problems by themselves.

    2010-12-01

    The availability of and equitable access to, health services have challenged healthcare providers with a greater degree of urgency since the end of World War II. Prior to that time, concepts such as equity and social justice were just that, concepts but no real attempts were ever made to operationalize them. Goods and services were still produced and distributed based on market forces, that is, one's ability and willingness to pay for something. Health in that context was a service, some say a commodity, to be bought and sold, hence its availability was not necessarily commensurate with its accessibility.

    Purpose: This study explores new content, forms, and fields of science and technology(S&T;) innovation and entrepreneurship information services of the National Science Library of the Chinese Academy of Sciences(NSLC).Design/methodology/approach: We cooperated with incubator enterprises and set up an "S&T; Innovation and Entrepreneurship Information Service Platform." We designed five series of activities, including industrial information release, project financing and roadshows, entrepreneurial sharing, entrepreneurial coaching sessions, and entrepreneurial salons. Based on the implementation of these activities, we designed new NSLC library services for S&T; innovation and entrepreneurship.Findings: Since the construction of the platform, these five series of activities have attracted more than 80 business projects, 90 investors, and 30 researchers. Furthermore, more than 20 media representatives and nearly 300 entrepreneurs have participated in the activities that the NSLC has organized in the past two years. Through these activities, we have defined an S&T; innovation and entrepreneurship knowledge service model for the NSLC.Research limitations: The service practice of the NSLC is still in the demonstration phase. Due to staffing limitations of our service teams, the expansion of our service activities has been greatly restricted.Practical implications: The innovation and entrepreneurship information services of the NSLC provide a lot of material for transformation of library services for domestic and foreign special libraries.Originality/value: It is useful to transform library and business services by embedding them into ways in which we serve innovation and entrepreneurial activities. This opens up a new field of library knowledge services in China.

    Understanding and developing effective strategies for the use of community-engaged learning (service-learning) approaches in the environmental geosciences is an important research need in curricular and pedagogical innovation for sustainability. In 2015, we designed and implemented a new community-engaged learning practicum course through the Earth Systems Program in the School of Earth, Energy and Environmental Sciences at Stanford University focused on regional open space management and land stewardship. Undergraduate and graduate students partnered with three different regional land trust and environmental stewardship organizations to conduct quarter-long research projects ranging from remote sensing studies of historical land use, to fire ecology, to ranchland management, to volunteer retention strategies. Throughout the course, students reflected on the decision-making processes and stewardship actions of the organizations. Two iterations of the course were run in Winter and Fall 2015. Using coded and analyzed pre- and post-course student surveys from the two course iterations, we evaluate undergraduate and graduate student learning outcomes and changes in perceptions and understanding of sustainability science. We find that engagement with community partners to conduct research projects on a wide variety of aspects of open space management, land management, and environmental stewardship (1) increased an understanding of trade-offs inherent in sustainability and resource management and (2) altered student perceptions of the role of scientific information and research in environmental management and decision-making. Furthermore, students initially conceived of open space as purely ecological/biophysical, but by the end of the course, (3) their understanding was of open space as a coupled human/ecological system. This shift is crucial for student development as sustainability scientists.

The approach, according to which the individual parameters of graduating student’s output model’s professional characteristics, which he received after the examination of his work as Tower controller (ATM Unit of aerodrome control service, approach controller or area control service controller, are compared with the predetermined specialist’s competence reference model, relating to the special working place in ATM system, is supposed here. Notably, the conception, relating to the correspondence of the graduating student’s competence output level to the defined reference model of ATC controller, relating to the special working place of ATM Unit, is realised.

  18. Change over a service learning experience in science undergraduates' beliefs expressed about elementary school students' ability to learn science

    Science.gov (United States)

    Goebel, Camille A.

    This longitudinal investigation explores the change in four (3 female, 1 male) science undergraduates' beliefs expressed about low-income elementary school students' ability to learn science. The study sought to identify how the undergraduates in year-long public school science-teaching partnerships perceived the social, cultural, and economic factors affecting student learning. Previous service-learning research infrequently focused on science undergraduates relative to science and society or detailed expressions of their beliefs and field practices over the experience. Qualitative methodology was used to guide the implementation and analysis of this study. A sample of an additional 20 science undergraduates likewise involved in intensive reflection in the service learning in science teaching (SLST) course called Elementary Science Education Partners (ESEP) was used to examine the typicality of the case participants. The findings show two major changes in science undergraduates' belief expressions: (1) a reduction in statements of beliefs from a deficit thinking perspective about the elementary school students' ability to learn science, and (2) a shift in the attribution of students, underlying problems in science learning from individual-oriented to systemic-oriented influences. Additional findings reveal that the science undergraduates perceived they had personally and profoundly changed as a result of the SLST experience. Changes include: (1) the gain of a new understanding of others' situations different from their own; (2) the realization of and appreciation for their relative positions of privilege due to their educational background and family support; (3) the gain in ability to communicate, teach, and work with others; (4) the idea that they were more socially and culturally connected to their community outside the university and their college classrooms; and (5) a broadening of the way they understood or thought about science. Women participants stated

  19. Integrating Service-Learning Pedagogy for Preservice Elementary Teachers' Science Identity Development

    Science.gov (United States)

    Wilson, Rachel E.; Bradbury, Leslie U.; McGlasson, Martha A.

    2015-04-01

    The purpose of this article is to explore how preservice elementary teachers (PSETs) interpreted their service-learning experiences within a pre-methods environmentally focused course and how their interpretations shaped their science teaching identities. Along a continuum of service-learning experiences were events that emphasized science learning, that focused on science teaching, and that were transitional, with elements of both science learning and science teaching. These various service-learning experiences were designed to be "boundary experiences" for professional identity development (Geijsel & Meijers in Educational Studies, 3(4), 419-430, 2005), providing opportunities for PSETs to reflect on meanings in cultural contexts and how they are related to their own personal meanings. We analyzed written reflections and end-of-course oral reflection interviews from 42 PSETs on their various service-learning experiences. PSETs discussed themes related to the meanings they made of the service-learning experiences: (a) experiencing science in relation to their lives as humans and future teachers, (b) interacting with elementary students and other PSETs, and (c) making an impact in the physical environment and in the community. The connections that PSETs were making between the discursive spaces (service-learning contexts) and their own meaning-making of these experiences (as connected to their own interests in relation to their future professions and daily lives) shows evidence of the potential that various types of science service-learning experiences have for PSETs in developing inbound science teaching identity trajectories (Wenger in Communities of practice: Learning, meaning, and identity. Cambridge: Cambridge University Press, 1998). The findings of this study point to positive outcomes for PSETs when they participate in structured service-learning experiences along a learning to teaching continuum (246).

  6. Supporting pre-service science teachers in developing culturally relevant pedagogy

    Science.gov (United States)

    Krajeski, Stephen

    This study employed a case study methodology to investigate a near-authentic intervention program designed to support the development of culturally relevant pedagogy and its impact on pre-service science teachers' notions of culturally relevant pedagogy. The unit of analysis for this study was the discourse of pre-service science teachers enrolled in a second semester science methods course, which was the site of the intervention program. Data for this study was collected from videos of classroom observations, audio recordings of personal interviews, and artifacts created by the pre-service science teachers during the class. To determine how effective science teacher certification programs are at supporting the development of culturally relevant pedagogy without an immersion aspect, two research questions were investigated: 1) How do pre-service science teachers view and design pedagogy while participating in an intervention designed to support the development of culturally relevant pedagogy? 2) How do pre-service science teachers view the importance of culturally relevant pedagogy for supporting student learning? How do their practices in the field change these initial views?

  7. Adaptive management for ecosystem services (j/a) | Science ...

    Science.gov (United States)

    Management of natural resources for the production of ecosystem services, which are vital for human well-being, is necessary even when there is uncertainty regarding system response to management action. This uncertainty is the result of incomplete controllability, complex internal feedbacks, and non-linearity that often interferes with desired management outcomes, and insufficient understanding of nature and people. Adaptive management was developed to reduce such uncertainty. We present a framework for the application of adaptive management for ecosystem services that explicitly accounts for cross-scale tradeoffs in the production of ecosystem services. Our framework focuses on identifying key spatiotemporal scales (plot, patch, ecosystem, landscape, and region) that encompass dominant structures and processes in the system, and includes within- and cross-scale dynamics, ecosystem service tradeoffs, and management controllability within and across scales. Resilience theory recognizes that a limited set of ecological processes in a given system regulate ecosystem services, yet our understanding of these processes is poorly understood. If management actions erode or remove these processes, the system may shift into an alternative state unlikely to support the production of desired services. Adaptive management provides a process to assess the underlying within and cross-scale tradeoffs associated with production of ecosystem services while proceeding with manage

    Hemoglobinopathies and thalassemias are the most frequent genetic hereditary disorders with an increasing global health burden, especially in low- and middle-income countries. We aimed to determine the epidemiologic pattern of hemoglobinopathies and thalassemias in individuals referred to the Haematology Research Centre, Shiraz University of Medical Sciences, Shiraz, Iran, which is the most important referral center in Southern Iran during 2006 to 2011. The most frequent abnormality was β-thalassemia (β-thal) minor (24.0%), followed by α-thalassemia (α-thal) trait (10.0%), hemoglobin (Hb) S trait (4.0%) and Hb D-Punjab trait (4.0%). Because this center is a referral center, we detected a higher prevalence compared to the normal population; however, these data could help policymakers and health service providers to better programming for prevention of births affected with Hb disorders.

  17. A study of understanding: Alchemy, abstraction, and circulating reference in tertiary science education

    Science.gov (United States)

    Merritt, Brett W.

    Understanding is widely touted to be of paramount importance for education. This is especially true in science education research and development where understanding is heralded as one of the cornerstones of reform. Teachers are expected to teach for understanding and students are expected to learn with understanding. This dissertation is an empirical study of the concept of understanding. After analyzing various constructions of understanding in current U.S. education literature, I suggest that understanding is defined by five distinct features---they are knowledge (or knowledge base), coherence, transfer, extrapolation, and cognition--- and that these features are heavily informed and shaped by the psychological sciences. This relationship is neither good nor bad, I argue, but it means that teaching for and learning with understanding are not heavily informed and shaped by, for example, the natural sciences. Drawing from historical, philosophical, and anthropological perspectives of science, but especially from the work of Bruno Latour, I enact a radical revision(ing) of psychological notions such as "abstraction" and "transfer." The two main purposes of this re-visioning are (1) to draw critical attention to particular characteristics of a cognitive learning theory that emphasizes abstract concepts, and (2) to align many of the principles and tools used in science education more closely with those used in empirical scientific research. Finally, by bringing some examples of teaching and learning from an undergraduate biology classroom into conversation with both psychological and empirical practices and perspectives, I suggest that problematizing the current construction of understanding creates much needed room in mainstream science education for more empirical forms of learning and styles of teaching. A shift to such forms and styles, I conclude, should prove to be more inclusive and less constraining for both students and teachers.

    Project ALERT (Augmented Learning Environment and Renewable Teaching) was founded in 1998, with funding from NASA and the California State University (CSU), to improve earth system science education for pre-service teachers. Project ALERT has formed linkages between ten campuses of the CSU, which prepares about 60 percent of California's teachers, and two NASA centers, Ames Research Center and the Jet Propulsion Laboratory. ALERT has also fostered alliances between earth science and science education faculty. The combined expertise of Project ALERT's diverse partners has led to a wide array of activities and products, including: 1) incorporation in university classrooms of NASA-developed imagery, data, and educational resources; 2) creation and/or enhancement of several courses that bring earth systems science to pre-service teachers; 3) fellowships for CSU faculty to participate in collaborative research and education projects at the NASA Centers; 4) development of teaching modules on such varied topics as volcanoes, landslides, and paleoclimate; and 5) a central web site that highlights resources for teaching introductory Earth system science. An outgrowth of Project ALERT is the increased interest on the part of CSU earth scientists in education issues. This has catalyzed their participation in other projects, including NASA's Project NOVA, Earth System Science Education Alliance, and Sun-Earth Connection Education Forum, the Digital Library for Earth System Science Education, and the California Science Project. Project ALERT has also expanded to provide professional development opportunities for in-service teachers, as exemplified by its support of the Bay Area Earth Science Institute (BAESI) at San Jose State University. Each year, BAESI offers 10-15 full-day workshops that supply teachers and teachers-to-be with a blend of science concepts and classroom activities, free instructional materials, and the opportunity to earn inexpensive university credit.

    Vasavada, Ashwin R.

    Same planet, different worlds—that's how many scientists see the relationship between science and government. Yet science and technology have become so infused into society that those worlds are colliding. Today, a number of national issues share a strong connection to science, from stem cells to climate change and energy to bioterrorism. For scientists who can adapt to the culture of politics, working in the collision zone can be an exciting and rewarding way to spend a year or even a career.This past year, I was one of 35 scientists in Washington serving as Congressional Science and Technology Fellows, sponsored by a number of scientific societies, including AGU. The Fellows vary widely in age and carry resumes listing Ph.D.s in not only physics, biology, and chemistry but also in Earth science, food safety, psychology, and veterinary medicine. With a group like that, weekly lunches and happy hours become the kind of broadening experience that one rarely gets in focused academic departments. And then there's the politics.

    2018-02-01

    Full Text Available Many educators and educational institutions worldwide have agreed that the main goal of science education is to produce a scientifically literate community. Science teachers are key to the achievement of scientific literacy at all levels of education because of the essential role they play in preparing scientifically literate individuals. Studies show that pre-service elementary teachers need to build more confidence in teaching science and scientific literacy during their teacher education programs in order for them to successfully teach science knowledge to their students. Therefore, the purpose of this study is threefold. First, pre-service elementary teachers' scientific literacy levels were examined. Second, pre-service teachers' self-efficacy beliefs were measured by distinguishing between their personal and subject-specific self-efficacy beliefs. Third, the extent to which pre-service elementary teachers' scientific literacy levels and self-efficacy levels are related was investigated. Participants were 49 pre-service elementary teachers registered in two science methods courses (introductory and advanced at a mid-sized university in the United States. Quantitative data were collected using the Test of Basic Scientific Literacy, the Science Teaching Efficacy Belief Instrument-Preservice, and Beliefs about Teaching. Results showed that participants had a satisfactory level of scientific literacy. However, pre-service teachers had borderline scores on the Nature of Science scale. Regarding self-efficacy, findings showed that both groups had the highest self-efficacy in teaching biology and the lowest in teaching physics. Participants in the advanced science methods course exhibited a moderate preexisting positive relationship between scientific literacy and subject-specific self-efficacy in teaching science.

    This study was conducted on the effect of understanding and instruction of the nature of science of Ms. Wanida, a pre-service student under science education program in biology, Faculty of Education, Khon Kaen University. Wanida was a teaching practicum student majoring in biology at Khon Kaen University Demonstration School (Modindaeng). She was teaching biology for 38 Grade 10 students. Methodology regarded interpretive paradigm. The study aimed to examine 1) Wanida's understanding of the nature of science, 2) Wanida's instruction of the nature of science, 3 students' understanding of the nature of science from Wanida's instruction, and 4) the effects of Wanida's understanding and instruction of the nature of science on students' understanding of the nature of science from Wanida's instruction. Tools of interpretation included teaching observation, a semi-structured interview, open-ended questionnaire, and an observation record form for the instruction of the nature of science. The data obtained was interpreted, encoded, and classified, using the descriptive statistics. The findings indicated that Wanida held good understanding of the nature of science. She could apply the deficient nature of science approach mostly, followed by the implicit nature of science approach. Unfortunately, she could not show her teaching as explicit nature of science. However, her students' the understanding of the nature of science was good.

    Full Text Available Objective: To analyze the vaccine schedule for preterm infants in a program of special immunobiologicals. Methods: A documental study conducted at a Reference Center of Special Immunobiologicals (CREATE situated in a general hospital of tertiary care in pediatrics. The sample consisted of 112 newborns with gestational age below 37 weeks and weighing less than 2500g, suitable for vaccination, assisted in 2006-2007. Data collection was done from registration forms, reference records and registers of control of special immunobiologicals’ administration, in year 2008. Results: The results showed that 22 (20% newborns were weighing between 1000 and 1499g. Regarding gestational age, 39 (35% were born between 30 and 34 weeks of pregnancy. Most proceeded from public institutions, 37 (69%. The vaccination schedule of most children, 68 (61%, was incomplete. The main clinical indications for special immunobiologicals were prematurity and bronchopulmonary dysplasia. It was observed that 89% (n = 100 of preterm infants received the pneumococcal vaccine (Prevenar. For preterm infants who were at risk of developing serious events related to the tetravalent vaccine, it was elected the scheme Prevenar + DTPa + Hib. Simultaneous administration of meningococcal conjugate vaccines - C (MncC with Prevenar was indicated for candidates for cochlear implants. Conclusion: The integral care to the preterm newborn involves early immunization, that is, the one that starts in the neonatal unit, and requires the inclusion of special immunobiologicals, which should be criteriously recommended.

    For a cloud-based telecardiology solution to be established in any scenario, it is necessary to ensure optimum levels of security, as patient's data will not be in the same place from where access is gained. The main objective of this article is to present a secure, cloud-based solution for a telecardiology service in different scenarios: a hospital, a health center in a city, and a group of health centers in a rural area. iCanCloud software is used to simulate the scenarios. The first scenario will be a city hospital with over 220,000 patients at its emergency services, and ∼1 million outpatient consultations. For the health center in a city, it serves ∼107,000 medical consultations and 16,700 pediatric consultations/year. In the last scenario, a group of health centers in a rural area serve an average 437.08 consultations/month and around 15.6 a day. Each one of the solutions proposed shares common features including the following: secure authentication through smart cards, the use of StorageGRID technology, and load balancers. For all cases, the cloud is private and the estimated price of the solution would cost around 450 €/month. Thanks to the research conducted in this work, it has been possible to provide an adapted solution in the form of a telecardiology service for a hospital, city health center, and rural health centers that offer security, privacy, and robustness, and is also optimum for a large number of cloud requests.

    This study examines clinical and family predictors of perceived need for treatment and engagement in mental health treatment services among community-referred racial/ethnic minority adolescents and their primary caregivers. Findings indicated that the majority of families perceived a need for treatment, but that perceived need was not associated with treatment engagement. Family factors (i.e., low cohesion and high conflict within the family) predicted perceived need for treatment among adolescents, whereas clinical factors (i.e., adolescent internalizing and externalizing symptomatology) predicted caregiver perceived need for adolescent treatment. Neither clinical nor family factors predicted treatment engagement.

    Experiences of the Laboratory for Instrumental Neutron Activation Analysis (INAA) of the Reactor Institute Delft at the Delft University of Technology are presented on basis of more than 30 years experience with INAA services to others. Recommendations are given to neutron activation analysis groups starting as a service provider, but also pitfalls are identified. The importance of fitness for intended purpose is emphasized, so that analysis protocols should be optimized to answer the customer’s basic question, rather than to yield the highest number of elements and best level of precision. The absence of automation and no return of revenues are identified as highest threats of becoming a successful and reliable partner for providing services. (author)

  2. No Reference Video-Quality-Assessment Model for Monitoring Video Quality of IPTV Services

    Science.gov (United States)

    Yamagishi, Kazuhisa; Okamoto, Jun; Hayashi, Takanori; Takahashi, Akira

    Service providers should monitor the quality of experience of a communication service in real time to confirm its status. To do this, we previously proposed a packet-layer model that can be used for monitoring the average video quality of typical Internet protocol television content using parameters derived from transmitted packet headers. However, it is difficult to monitor the video quality per user using the average video quality because video quality depends on the video content. To accurately monitor the video quality per user, a model that can be used for estimating the video quality per video content rather than the average video quality should be developed. Therefore, to take into account the impact of video content on video quality, we propose a model that calculates the difference in video quality between the video quality of the estimation-target video and the average video quality estimated using a packet-layer model. We first conducted extensive subjective quality assessments for different codecs and video sequences. We then model their characteristics based on parameters related to compression and packet loss. Finally, we verify the performance of the proposed model by applying it to unknown data sets different from the training data sets used for developing the model.

    Full Text Available Abstract Background: Brugada syndrome (SBr is an arrhythmic condition characterized by ST-T segment abnormalities in the right precordial leads associated with a high risk of ventricular arrhythmias and sudden death. Local data regarding the clinical characteristics of patients with a typical electrocardiographic (ECG pattern undergoing electrophysiological study are scarce. Objective: To evaluate patients with an ECG pattern suggestive of SBr referred for electrophysiological evaluation in a specialized center. Methods: Cohort study of patients referred for electrophysiological study because of an ECG pattern compatible with SBr between January 1998 and March 2017. Results: Of the 5506 procedures, 35 (0.64% were for SBr investigation, 25 of which (71.42% were performed in men. The mean age was 43.89 ± 13.1 years. The ECG patterns were as follows: type I, 22 (62.85%; type II, 12 (34.30%; and type III, 1 (2.85%. Twenty-three patients (65.7% were asymptomatic, 6 (17.14% had palpitations, 5 (14.3% had syncope, and 3 (8.6% had a family history of sudden death. Electrophysiological study induced ventricular tachyarrhythmias in 16 cases (45.7%, the mean ventricular refractory period being 228 ± 36 ms. Ajmaline / procainamide was used in 11 cases (31.4%, changing the ECG pattern to type I in 7 (63.6%. Sixteen cases (45.7% received an implantable cardioverter defibrillator (ICD. In a mean 5-year follow-up, 1 of the 16 patients (6.25% with ICD had appropriate therapy for ventricular fibrillation. There was no death. Other arrhythmias occurred in 4 (11.4% cases. Conclusions: Most patients are men, and a type I ECG pattern is the main indication for electrophysiological study. Class IA drugs have a high ECG conversion rate. The ICD event rate was 6%.

A mixed methods approach was used with an online survey to collect data on use of information technologies in community pharmacy, followed by an exploratory observational time and business processes study, which use the shadowing method to identify and assess the opportunity to lunch online services. Combining this with the Service Experiment Blueprint and the Dáder method an enhanced pharmaceutical service was designed. Next, an artifact is developed and a prototype is implemented to demonstrate the value of online pharmaceutical services' delivery. This new service could represent a new perspective for pharmaceutical services integration within the health system.

    Psychological distress is common in patients with cancer and psychological well-being is increasingly seen as an important component of cancer care. The aim of this study was to examine the relationship between cancer type and subjective distress. The following data were collected from a database of consecutive psycho-oncology referrals to the Liaison Psychiatry service in Cork University Hospital from 2006 to 2015: demographics, cancer diagnosis, Distress Thermometer (DT) score. 2102 out of 2384 referrals were assessed. Of those assessed, the most common cancer diagnoses were breast (23%, n=486) followed by haematological (21%, n=445). There were significant difference in DT score between the different cancer types, (χ2(13)=33.685, p=0.001, Kruskal–Wallis test). When adjusted for age, gender and whether or not the cancer was recently diagnosed, there was no significant association between cancer type and psychological distress. In conclusion, cancer type is not associated with level of distress in cancer.

    to identify changes in the food intake patterns among overweight children and teenagers, treated at a reference medical centre. the method used is that of a cohort study, between April 2010 and April 2011. A total of 109 children and teenagers, either obese or overweight, took part in the study. The population was divided into two subgroups depending on the permanence period (more than 6 months, and less than 6 months off the treatment). The chi-square test and logistic regression were carried out. the group which had been longer off the treatment tended to consume more soft drinks, pasta and fried foods, and less fruit and vegetables. The group with less time showed an improvement, with a reduction of consumption of soft drinks and other goodies. There was confirmation of an increased risk for consumption of soft drinks, pasta and goodies in general, as also detachment from the treatment in adolescence. The group with a longer period of monitoring has had a positive change in food intake frequency. The main contribution made by this study is that of showing that multiprofessional treatment, including some nursing care, is efficient in progressively changing the food intake of children and adolescents who are overweight.

    The purposes of this study were to identify the in-service needs of high school science teachers in Istanbul, Turkey according to the subgroups such as school type and gender and determine the priority obstacles preventing these science teachers from attendance at in-service programs. Moreover, this study aimed to find the other greatest needs of high school science teachers that are not mentioned in the survey instrument. The data for this research was gathered by conducting a survey in Istanbul, Turkey in Fall 2001 and Spring 2002 Semesters. Turkish translation of the modified version of a science teacher's needs inventory, Science Teacher Inventory of Need (STIN), entitled STIN-2 was used as the survey instrument. The subjects consisted of 75 high school science teachers who were selected from 369 high schools by using stratified random sampling in grades nine through eleven. By personally administering the survey, 422 science teachers from 75 high schools completed the survey and a 97% response rate was achieved. The results obtained in this study show that Turkish high school science teachers in Istanbul have a number of shared needs. One other indication is that they also have a number of needs, which are specific to subgroups of those science teachers.

    The study examined parent stress and health-related quality of life (HRQOL) among families of children with congenital heart disease (CHD) referred for psychological services. Parents of 54 children (85% boys) aged 3 to 13 (M age  = 7.48, SD = 2.38) completed measures to assess parenting stress (Parenting Stress Index - Short Form; Pediatric Inventory for Parents) and the PedsQL Family Impact Module. Medical information was retrieved from medical record review. Half of parents of children with single ventricle anatomy had clinically significant levels of parenting stress. Parents of children with single ventricle anatomy reported more frequent illness-related stress and more difficulty dealing with illness-related stress than parents of children with two ventricle anatomy. Younger gestational age at birth and referral for attention or behavior problems were associated with greater likelihood of parent at-risk psychosocial functioning. Among children referred for psychological services, many parents report significant stress and significant negative impact of the child's medical condition on the family. Results underscore the need to consider assessing parent psychosocial functioning and providing additional support for parents of children with CHD. © 2017 Wiley Periodicals, Inc.

    In infants, it is not always easy to distinguish between pathological and physiological gastroesophageal reflux based only on clinical criteria. In Brazil, studies about gastroesophageal reflux disease in infants are few and are even rare those that used prolonged esophageal pH monitoring for its evaluation. To describe the clinical features of gastroesophageal reflux disease and to determine its prevalence in infants with gastroesophageal reflux attending a tertiary Pediatric Gastroenterology Service and submitted to esophageal pH monitoring for investigation. Descriptive study in 307 infants in whom esophageal pH monitoring (Mark III Digitrapper, Synectics Medical AB, Sweden) was performed during the period December, 1998-December, 2008. The clinical features studied were age group (1-12 months and 13-24 months), and clinical manifestations that motivated the indication of pH monitoring. One hundred twenty-four (40.4%) were female and 183 (59.6%) male with mean age 12.2 +/- 6.2 months (1-23 months). The prevalence of gastroesophageal reflux disease was 18.2% (56/307). One hundred forty-eight (48.2%) were 1-12 months old and 159 (51.8%), 13-24 months. No significant difference was found between the prevalence of these two age groups (P = 0.3006). Gastroesophageal reflux disease was more frequent in those with digestive manifestations (24.2%), crisis of cyanosis/apnea (23.8%) and mixed manifestations (21.5%). Respiratory manifestations were the most frequent indication (39.1%) of pH monitoring. However, the prevalence of gastroesophageal reflux disease was lower (12.5%) in this group compared with in those with digestive manifestations (P = 0.0574), crisis of cyanosis/apnea (P = 0.0882) and mixed manifestations (P = 0.1377). All infants that presented clinical manifestations as crisis of cyanosis/apnea and abnormal pH-metry were Service, the prevalence of gastroesophageal reflux disease associated with acid reflux in infants revealed elevated.

    The use of Web Services to enable programmatic access to on-line bioinformatics is becoming increasingly important in the Life Sciences. However, their number, distribution and the variable quality of their documentation can make their discovery and subsequent use difficult. A Web Services registry with information on available services will help to bring together service providers and their users. The BioCatalogue (http://www.biocatalogue.org/) provides a common interface for registering, browsing and annotating Web Services to the Life Science community. Services in the BioCatalogue can be described and searched in multiple ways based upon their technical types, bioinformatics categories, user tags, service providers or data inputs and outputs. They are also subject to constant monitoring, allowing the identification of service problems and changes and the filtering-out of unavailable or unreliable resources. The system is accessible via a human-readable 'Web 2.0'-style interface and a programmatic Web Service interface. The BioCatalogue follows a community approach in which all services can be registered, browsed and incrementally documented with annotations by any member of the scientific community.

    Ayurveda is serving the mankind for centuries with a holistic approach. This system has preached to treat the diseases which are only curable by the physicians. It has advised the physicians to strictly avoid treating the incurable diseases. In order to assess the incurability of the diseases or the incurable state of a patient; this system has preached the signs and symptoms of incurability which are known as arista-vijnana, which have been described in Brhattrayi of Ayurveda. Though Caraka has placed them in a separate section of his treatise, Cakrapani and Dalhana have also spent a considerable portion in their commentaries dealing with arista-vijnana. They were two renowned scholars who have commented with a depth of wisdom on Susruta Samhita. In this paper, the author has tried to present the comparative and critical comments of both commentators based on Bhanumati and Nibandha Samgraha, respectively, over arista-vijnana as described in Sutrasthana of Susruta Samhita. Dalhana was greatly influenced by Caraka Samhita with regard to the prognostic science. On the other hand, Cakrapani repeatedly recognized the superiority of the indriya-sthana of Caraka Samhita with regard to analysis of prognostic science. PMID:22408294

    The Genesis mission collected solar wind for 27 months at Earth-Sun L1 on both passive and active collectors carried inside of a Science Canister, which was cleaned and assembled in an ISO Class 4 cleanroom prior to launch. The primary passive collectors, 271 individual hexagons and 30 half-hexagons of semiconductor materials, are described in. Since the hard landing reduced the 301 passive collectors to many thousand smaller fragments, characterization and posting in the online catalog remains a work in progress, with about 19% of the total area characterized to date. Other passive collectors, surfaces of opportunity, have been added to the online catalog. For species needing to be concentrated for precise measurement (e.g. oxygen and nitrogen isotopes) an energy-independent parabolic ion mirror focused ions onto a 6.2 cm diameter target. The target materials, as recovered after landing, are described in. The online catalog of these solar wind collectors, a work in progress, can be found at: http://curator.jsc.nasa.gov/gencatalog/index.cfm This paper describes the next step, the cataloging of pieces of the Science Canister, which were surfaces exposed to the solar wind or component materials adjacent to solar wind collectors which may have contributed contamination.

    1999-01-01

    The IAEA International Physical protection Advisory Service (IPPAS) provides advice to Member States to assist them in strengthening the effectiveness of their national physical protection system whilst recognizing the ultimate responsibility for physical protection is that of the Member State. The IPPAS is available to all countries with nuclear materials and facilities. The basic concepts, purposes and functions of physical protection are provided in INFCIR/225, 'The Physical Protection of Nuclear Material and Nuclear Facilities' as amended from time to time and 'the Convention on the Physical Protection of Nuclear Material (INFCIR/247/Rev.1). The guidance given in INFCIR/225 recognizes that implementation of these requirements vary from country to country depending on their existing constitutional, legal and administrative systems; the assessment of the threat for the potential theft of nuclear material or sabotage of nuclear facilities; the technical skills and professional and financial resources available to the competent authority; and social customs and cultural traditions. IPPAS missions are performance oriented in that they accept different approaches to the implementation of national physical protection system

    Misdiagnosis of heparin-induced thrombocytopenia (HIT) is common and exposes patients to high-risk therapies and potentially serious adverse events. The primary objective of this study was to evaluate the impact of collaboration between an inpatient pharmacy-driven anticoagulation management service (AMS) and hospital reference laboratory to reduce inappropriate HIT antibody testing via pharmacist intervention and use of the 4T pre-test probability score. Secondary objectives included clinical outcomes and cost-savings realized through reduced laboratory testing and decreased unnecessary treatment of HIT. This was a single center, pre-post, observational study. The hospital reference laboratory contacted the AMS when they received a blood sample for an enzyme-linked immunosorbent HIT antibody (HIT Ab). Trained pharmacists prospectively scored each HIT Ab ordered by using the 4T score with subsequent communication to physicians recommending for or against processing and reporting of lab results. Utilizing retrospective chart review and a database for all patients with a HIT Ab ordered during the study period, we compared the incidence of HIT Ab testing before and after implementation of the pharmacy-driven 4T score intervention. Our intervention significantly reduced the number of inappropriate HIT Ab tests processed (176 vs. 63, p reference laboratories can result in reduction of misdiagnosis of HIT and significant cost savings with similar safety.

  1. Variations in Primary Teachers’ Responses and Development during Three Major Science In- Service Programmes

    2011-01-01

    Full Text Available This paper reports on how different types of teachers responded to in-service aimed at developing investigative-based science education (IBSE in primary schools, and the extent to which they applied their new skills in the classroom. Common items from evaluation questionnaires allowed data to be combined from three major in-service programmes. Using complete data sets from 120 teachers, cluster analysis enabled three teacher types to be identified: a small group of ‘science unsures’, with low attitude scores and little confidence, who showed no response to the innovation; ‘holistic improvers’, who showed the largest improvement in science teaching confidence; and ‘high level, positive progressives’, who were very positive to science teaching throughout and showed gains in confidence in teaching physics and chemistry, as well as in demonstrating the relevance of science to their pupils. Taking account of these teacher types alongside interviews and observations, nine developmental stages in how teachers apply their new expertise in the classroom and the whole school are suggested. Major factorsinfluencing application in the classroom are the teachers’ initial science knowledge and pedagogical expertise, and motivating feedback to teachers when pupils responded positively to the innovation. Assessing teachers’ initial level of subject knowledge and science pedagogical expertise to inform the approach and amount of in-service provision is important. Subsequent mentoring as well as support from the school principal when teachers first try IBSE with pupils promotes successful implementation in the classroom.

    about their own subject matter knowledge may, for a large subgroup in the cohort, affect how the teachers‘ approach the physics content when teaching primary Science & Technology (grade 1-6 in the Danish schools). Beside this the cohort can be divided into subgroups with great variation in strengths......Results from a survey of a local cohort of newly qualified Danish science teachers before they began their first jobs in primary and lower secondary schools (n=110) show a need for continual Professional Development (PD). The results highlight two main areas of concern based on the newly qualified...... teachers´ reflections on scenarios of science teaching, their considerations about themselves as future science teachers etc. These include a tendency for the teachers to limit Inquiry Based Science Teaching to activity driven science, which suggests there is a need both in in-service PD and pre...

    2018-05-01

    Full Text Available Psychocardiology is a science that combines an insight of biomedicine, psychology and sociology sciences. The goal of this discipline is to study the relationship between psychological profile, personality, social functioning and cardiovascular diseases (CVD. Low socio-economic status, deficiency of social support, stress in work environment and in family life, depression, anxiety as well as hostility are partly responsible for risk of developing CVD and a poor prognosis of CVD. In everyday practice of physician clinical interview should be used to identify these psychosocial risk factors. After identification of psychosocial problems multimodal behavioural interventions are recommended to implement in treatment process. They should involve health education, physical activity, psychological and pharmacological therapy and learning of techniques of coping with illness and unfavorable social circumstances. Psychosocial risk factors of cardiovascular diseases are not widely recognized as a cardiovascular risk factor in their own right. However, they contribute to deterioration of treatment adherence and annihilate attempts of lifestyle improving. The pronounced psychosocial aspects of cardiovascular diseases pathogenesis make health promotion in patients and whole population difficult. Thus, considered factors are ponderous public health problem.

    2010-12-01

    Accelerating demographic trends in the United States attest to the critical need to broaden access to customized learning: reports refer to the next decade as the era of “extreme diversity” in K-12 classrooms, particularly in large urban school districts. This diverse student body possesses a wide range of knowledge, skills, and abilities in addition to cultural differences. A single classroom may contain students with different levels of quantitative skills, different levels of English language proficiency, and advanced students preparing for college-level science. A uniform curriculum, no matter how well designed and implemented, cannot possibly serve the needs of such diverse learners equally well. Research has shown positive learning outcomes when pedagogical strategies that customize instruction to address specific learner needs are implemented, with under-achieving students often benefiting most. Supporting teachers in the effective adoption and use of technology to meet these instructional challenges is the underlying goal of the work to be presented here. The Curriculum Customization Service (CCS) is an integrated web-based platform for middle and high school Earth science teachers designed to facilitate teachers’ instructional planning and delivery; enhancing existing curricula with digital library resources and shared teacher-contributed materials in the context of articulated learning goals. The CCS integrates interactive resources from the Digital Library for Earth System Education (DLESE) with an inquiry-based curriculum component developed by the American Geological Institute (EarthComm and Investigating Earth Systems). The digital library resources emphasize visualizations and animations of Earth processes that often challenge students’ understanding, offering multiple representations of phenomena to address different learning styles, reading abilities, and preconceived ideas. Teachers can access these materials, as well as those created or

A science methods class that is activity-based and student-centered, rather than lecture-based and teacher-centered, peaks their interest in science and alleviates their fears. Activities conducted by the students illustrate science concepts or integrate science with children`s literature books such as The Grouchy Ladybug. These activities are conducted by each student with the rest of the class and the professor acting as an elementary class. Each activity is then evaluated as to the science concept, what was done well, and how it could be improved. The students also relate how the activity would be integrated with other subjects such as social studies, art, math, and language arts. Student feedback indicates this method is enjoyable, educational, and valuable in preparing them to teach science. The {open_quotes}oohs{close_quotes} and {open_quotes}I didn`t know that!{close_quotes} during activities are positives, but students have also learned some science, lost most of their science anxiety, and will teach science with the confidence and enthusiasm that was lacking at the beginning of the course.

    The climate sciences represent a big data domain that is experiencing unprecedented growth. In our efforts to address the big data challenges of climate science, we are moving toward a notion of Climate Analytics-as-a-Service (CAaaS). We focus on analytics, because it is the knowledge gained from our interactions with big data that ultimately product societal benefits. We focus on CAaaS because we believe it provides a useful way of thinking about the problem: a specialization of the concept of business process-as-a-service, which is an evolving extension of IaaS, PaaS, and SaaS enabled by cloud computing. Within this framework, cloud computing plays an important role; however, we see it as only one element in a constellation of capabilities that are essential to delivering climate analytics-as-a-service. These elements are essential because in the aggregate they lead to generativity, a capacity for self-assembly that we feel is the key to solving many of the big data challenges in this domain. This poster will highlight specific examples of CAaaS using climate reanalysis data, high-performance cloud computing, map reduce, and the Climate Data Services API.

    Understanding the role of the diet in determining human health and disease is one major objective of modern nutrition. Mammalian biocomplexity necessitates the incorporation of systems biology technologies into contemporary nutritional research. Metabonomics is a powerful approach that simultaneously measures the low-molecular-weight compounds in a biological sample, enabling the metabolic status of a biological system to be characterized. Such biochemical profiles contain latent information relating to inherent parameters, such as the genotype, and environmental factors, including the diet and gut microbiota. Nutritional metabonomics, or nutrimetabonomics, is being increasingly applied to study molecular interactions between the diet and the global metabolic system. This review discusses three primary areas in which nutrimetabonomics has enjoyed successful application in nutritional research: the illumination of molecular relationships between nutrition and biochemical processes; elucidation of biomarker signatures of food components for use in dietary surveillance; and the study of complex trans-genomic interactions between the mammalian host and its resident gut microbiome. Finally, this review illustrates the potential for nutrimetabonomics in nutritional science as an indispensable tool to achieve personalized nutrition.

    NHS policy documents continue to make a wide-ranging commitment to patient involvement. The Patient Participation Direct Enhanced Service (PP-DES), launched in 2011, aimed to ensure patients are involved in decisions about the range and quality of services provided and commissioned by their practice through patient reference groups (PRGs). The aim of this exploratory study is to review the impact of the PP-DES (2011-13) on a sample of PRGs and assess how far it has facilitated their involvement in decisions about the services of their general practices. A qualitative methods design, using semi- structured interviews and focus groups, was employed to explore the experiences and views of GP practice staff (n = 24), PRG members (n = 80) at 12 GP practices, and other stakeholders (n = 4). Wide variation in the role and remit of the participating PRGs was found, which broadly ranged from activities to improve practice resources to supporting health promotion activities. The majority of PRG members were unfamiliar with the PP-DES scheme and its aims and purpose. Stakeholders and practice staff felt strongly that the main success of the PP-DES was that it had led to an increase in the number of PRGs being established in the locality. The PP-DES scheme has been a catalyst to establish PRGs. However, the picture was mixed in terms of the PRGs involvement in decisions about the services provided at their general practice as there was wide variation in the PRGs role and remit. The financial incentive alone, provided via the DES scheme, did not secure greater depth of PRG activity and power, however, as social factors were identified as playing an important role in PRGs' level of participation in decision making. Many PRGs have to become more firmly established before they are involved as partners in commissioning decisions at their practice.

    Although quality orientation is one of the main priorities of any progressive organization, quality evaluation in organizations providing services such as hospitals is one of the key challenges, because in this sector quality is determined by many intangible factors. Applying the service quality gap model is one of the common tools for quality evaluation in the service sector. This paper seeks to evaluate this issue. The present descriptive study was carried out through a cross-sectional method in 2008. The participants of this study were patients who had been referred to Kerman University of Medical Sciences hospitals. The sample comprised 385 patients, the data were collected by SERVQUAL as a standard questionnaire, and data analysis was carried out on 385 completed questionnaires. In all five dimensions of quality, a gap was observed between patients' perceptions and expectations as follows: Assurance: -1.28, Empathy: -1.36, Responsiveness: -1.80, Tangibles: -1.86 and Reliability: -1.69. A paired T-test showed that the differences between quality perceptions and expectations are significant (p value SERVQUAL approach to hospital services of a developing country.

    Since the latter part of the 1990's, the English-speaking medical education community has been engaged in a debate concerning the types of research that should have priority. To shed light on this debate and to better understand its implications for the practice of research, 23 semi-structured interviews were conducted with "influential figures" from the community. The results were analyzed using the concept of "field" developed by the sociologist Pierre Bourdieu. The results reveal that a large majority of these influential figures believe that research in medical education continues to be of insufficient quality despite the progress that has taken place over the past 2 decades. According to this group, studies tend to be both redundant and opportunistic, and researchers tend to have limited understanding of both theory and methodological practice from the social sciences. Three factors were identified by the participants to explain the current problems in research: the working conditions of researchers, budgetary restraints in financing research in medical education, and the conception of research in the medical environment. Two principal means for improving research are presented: intensifying collaboration between PhD's and clinicians, and encouraging the diversification of perspectives brought to bear on research in medical education.

    Objective: The study aimed to explore and describe the extent and nature of reported potentially traumatic events and associated variables in adult patients referred for psychological services at the Free State Psychiatric Complex (FSPC, Bloemfontein. Methods: In this cross-sectional study, demographic information, diagnostic morbidity and co-morbidity, and presence and type of reported trauma exposure reported by patients during the initial assessment were obtained from files of adult patients seen during a one-year period (2010 at the out-patient unit and the in-patient affective ward at the FSPC. Data were captured on data record forms by the researchers and analysed by means of descriptive statistics, univariate analysis and logistic regression (SAS version 9.1. Results: Of the 192 adults (71.9% White and 67.2% female referred for psychological services,75.5% were diagnosed with mood disorders, 17.2% with anxiety disorders, 22.4% with substance-related disorders and 20.9% with cluster B personality disorders or traits. A total of 145 (75.5% reported past trauma exposure. The most frequently reported types of trauma exposure were traumatic death/injury of a loved one (37.0%, physical assault (24.5%, witnessed/threatened violence (19.3%, and sexual assault (17.7%. Women were more likely to have been exposed to trauma than men (OR 4.02, 95% CI 1.87–8.62, in particular to traumatic death of a loved one (OR 3.13, physical assault (OR 4.08, or sexual assault (OR 5.43. Conclusions: The findings of this study contribute to current data regarding the prevalence of exposure to trauma and its possible association with mental illness. The importance of comprehensive trauma exposure screening in routine psychiatric interviewing practices is highlighted.

    2016-05-01

    Background: There has been an increasing emphasis on empowering pre-service and in-service science teachers to attend student reasoning and use formative assessments to guide student learning in recent years. Purpose: The purpose of this study was to explore pre-service science teachers' pedagogical capacity for formative assessment. Sample: This study took place in Turkey. The participants include 53 pre-service science teachers in their final year of schooling. All but two of the participants are female. Design and methods: We used a mixed-methods methodology in pursing this inquiry. Participants analyzed 28 responses to seven two-tiered questions given by four students of different ability levels. We explored their ability to identify the strengths and weaknesses in students' answers. We paid particular attention to the things that the pre-service science teachers noticed in students' explanations, the types of inferences they made about students' conceptual understanding, and the affordances of pedagogical decisions they made. Results: The results show that the majority of participants made an evaluative judgment (i.e. the answer is correct or incorrect) in their analyses of students' answers. Similarly, the majority of the participants recognized the type of mistake that the students made. However, they failed to successfully elaborate on fallacies, limitations, or strengths in student reasoning. We also asked the participants to make pedagogical decisions related to what needs to be done next in order to help the students to achieve academic objectives. Results show that 8% of the recommended instructional strategies were of no affordance, 64% of low-affordance, and 28% were of high affordance in terms of helping students achieve the academic objectives. Conclusion: If our goal is to improve pre-service science teachers' noticing skills, and the affordance of feedback that they provide, engaging them in activities that asks them to attend to students' ideas

    Personal and family data forms, completed by women referred to breast cancer genetics clinics, are valuable tools for verification and extension of family history, crucial steps in accurate risk evaluation. A significant minority of women do not complete and return these forms, despite reminders, even when completion is a pre-requisite for a clinic appointment. To facilitate access of women at increased familial risk of breast cancer to screening and counselling services by investigating reasons for non-return of the forms. Based on a single regional 'breast cancer family' service in the UK, Analysis of quantitative data comparing women who did not return forms (n = 55) with those who had done so (n = 59), together with qualitative evaluation of potential barriers to form-completion through semi-structured telephone interviews with a random subset of 'non-returners' (n = 23). Non-returners have higher proportions of the very young (below the age at which surveillance could be offered) and of women from lower social deprivation categories. Interviews revealed that the majority of non-returners are anxious, rather than unconcerned about their breast cancer risk and circumstances and attitudes contributed to non-compliance. Twenty-one participants confirmed that they would welcome an appointment at a 'breast cancer family' clinic, but nine did not attend for the appointment. They were significantly younger than those who attend, but were not at lower familial risk. Many women who fail to complete and return a family history form would benefit from risk assessment and genetic counselling. Several steps are suggested that might help them access the relevant services. © 2014 John Wiley & Sons Ltd.

    Macaroglu, Esra

    The purpose of this research was to explore pre-service elementary teachers' developing understanding of scientific inquiry within the context of their elementary science teaching and learning. More specifically, the study examined 24 pre-service elementary teachers' emerging understanding of (1) the nature of science and scientific inquiry; (2) the "place" of scientific inquiry in school science; and (3) the roles and responsibilities of teachers and students within an inquiry-based learning environment. Data sources consisted primarily of student-generated artifacts collected throughout the semester, including pre/post-philosophy statements and text-based materials collected from electronic dialogue journals. Individual data sources were open-coded to identify concepts and categories expressed by students. Cross-comparisons were conducted and patterns were identified. Assertions were formed with these patterns. Findings are hopeful in that they suggest pre-service teachers can develop a more contemporary view of scientific inquiry when immersed in a context that promotes this perspective. Not surprisingly, however, the prospective teachers encountered a number of barriers when attempting to translate their emerging ideas into practice. More research is needed to determine which teacher preparation experiences are most powerful in supporting pre-service teachers as they construct a framework for science teaching and learning that includes scientific inquiry as a central component.

    This study examined the information-seeking behaviors of basic science researchers to inform the development of customized library services. A qualitative study using semi-structured interviews was conducted on a sample of basic science researchers employed at a university medical school. The basic science researchers used a variety of information resources ranging from popular Internet search engines to highly technical databases. They generally relied on basic keyword searching, using the simplest interface of a database or search engine. They were highly collegial, interacting primarily with coworkers in their laboratories and colleagues employed at other institutions. They made little use of traditional library services and instead performed many traditional library functions internally. Although the basic science researchers expressed a positive attitude toward the library, they did not view its resources or services as integral to their work. To maximize their use by researchers, library resources must be accessible via departmental websites. Use of library services may be increased by cultivating relationships with key departmental administrative personnel. Despite their self-sufficiency, subjects expressed a desire for centralized information about ongoing research on campus and shared resources, suggesting a role for the library in creating and managing an institutional repository.

    Hamzeh, Fouada

    Lesson Study is a widely used pedagogical approach that has been used for decades in its country of origin, Japan. It is a teacher-led form of professional development that involves the collaborative efforts of teachers in co-planning and observing the teaching of a lesson within a unit for evidence that the teaching practices used help the learning process (Lewis, 2002a). The purpose of this research was to investigate if Lesson Study enables pre-service teachers to improve their own teaching in the area of science inquiry-based approaches. Also explored are the self-efficacy beliefs of one group of science pre-service teachers related to their experiences in Lesson Study. The research investigated four questions: 1) Does Lesson Study influence teacher preparation for inquiry-based instruction? 2) Does Lesson Study improve teacher efficacy? 3) Does Lesson Study impact teachers' aspiration to collaborate with colleagues? 4) What are the attitudes and perceptions of pre-service teachers to the Lesson Study idea in Science? The 12 participants completed two pre- and post-study surveys: STEBI- B, Science Teaching Efficacy Belief Instrument (Enochs & Riggs, 1990) and ASTQ, Attitude towards Science Teaching. Data sources included student teaching lesson observations, lesson debriefing notes and focus group interviews. Results from the STEBI-B show that all participants measured an increase in efficacy throughout the study. This study added to the body of research on teaching learning communities, professional development programs and teacher empowerment.

    2018-01-01

    This paper aimed to investigate the existing ideas of nature of science (NOS) teaching in Thailand biology classroom. The study reported the existing ideas of nature of science (NOS) teaching of one biology teacher Mrs. Mali who had been teaching for 6 years at in a school in Khon Kaen city. Methodology regarded interpretive paradigm. Tools of interpretation included 2 months of classroom observation, interviewing, and questionnaire of NOS. The findings revealed Mali held good understanding of the nature of science in the aspect of the use of evidence, the aspect of knowledge inquiry through different observation and deduction, the aspect of creativity and imagination influencing science knowledge inquiry, and the aspect of changeable scientific knowledge. Her biology teaching indicated that she used both the deficient nature of science approach and the implicit nature of science approach. The implicit nature of science approach was applied mostly in 7 periods and only 2 periods were arranged using the deficient nature of science approach. The paper has implication for professional development and pre-service program on NOS teaching in Thailand.

    NASA's vast array of scientific data within its Distributed Active Archive Centers (DAACs) is especially valuable to both traditional research scientists as well as the emerging market of Earth Science Information Partners. For example, the air quality science and management communities are increasingly using satellite derived observations in their analyses and decision making. The Air Quality Cluster in the Federation of Earth Science Information Partners (ESIP) uses web infrastructures of interoperability, or Service Oriented Architecture (SOA), to extend data exploration, use, and analysis and provides a user environment for DAAC products. In an effort to continually offer these NASA data to the broadest research community audience, and reusing emerging technologies, both NASA's Goddard Earth Science (GES) and Land Process (LP) DAACs have engaged in a web services pilot project. Through these projects both GES and LP have exposed data through the Open Geospatial Consortiums (OGC) Web Services standards. Reusing several different existing applications and implementation techniques, GES and LP successfully exposed a variety data, through distributed systems to be ingested into multiple end-user systems. The results of this project will enable researchers world wide to access some of NASA's GES & LP DAAC data through OGC protocols. This functionality encourages inter-disciplinary research while increasing data use through advanced technologies. This paper will concentrate on the implementation and use of OGC Web Services, specifically Web Map and Web Coverage Services (WMS, WCS) at GES and LP DAACs, and the value of these services within scientific applications, including integration with the DataFed air quality web infrastructure and in the development of data analysis web applications.

    Bankson, Daniel D; Heim, Joseph A

    2014-01-01

    To optimize transportation processes, we present herein a contingency plan that coordinates interim measures used to ensure continued and timely services when climate based events might cause an interruption of the usual specimen transportation processes. As an example, we outline the implementation and effectiveness of a contingency plan for network laboratory courier automobile transportation during times of mountain pass highway closure. Data available from an approximately 3-year period from October 10, 2010 through August 29, 2013 revealed a total of 690 complete closures in the eastbound or westbound lanes of the Interstate-90 highway in the Snoqualmie Pass area in the state of Washington. Despite the frequency of closures, the Washington State Department of Transportation was effective in limiting the duration of closures. Road closures of less than 1 hour accounted for 58.7% of the total closures. No recorded closures prevented dispatched couriers from completing a prescheduled Snoqualmie Pass route. We identified no delays as being clinically significant, despite that there were 5 instances of delays greater than 4 hours. We implemented a contingency plan of aiding courier logistics during all times of pass closure. The plan includes an easy to interpret Condition Dashboard as a status indicator and a Decision Tree that references and summarizes information. Overall, the contingency plan allows for an objective, robust, proactive decision support system that has enabled operational flexibility and has contributed to continued safe, on-time specimen transportation; clients and courier and reference laboratory staff have appreciated these features and associated outcomes.

    Otake, Mihoko

    Purpose of this study is to explore service design method through the development of support service for prevention and recovery from dementia towards science of lethe. We designed and implemented conversation support service via coimagination method based on multiscale service design method, both were proposed by the author. Multiscale service model consists of tool, event, human, network, style and rule. Service elements at different scales are developed according to the model. Interactive conversation supported by coimagination method activates cognitive functions so as to prevent progress of dementia. This paper proposes theoretical bases for science of lethe. Firstly, relationship among coimagination method and three cognitive functions including division of attention, planning, episodic memory which decline at mild cognitive imparement. Secondly, thought state transition model during conversation which describes cognitive enhancement via interactive communication. Thirdly, Set Theoretical Measure of Interaction is proposed for evaluating effectiveness of conversation to cognitive enhancement. Simulation result suggests that the ideas which cannot be explored by each speaker are explored during interactive conversation. Finally, coimagination method compared with reminiscence therapy and its possibility for collaboration is discussed.

    2012-03-01

    Full Text Available In South Africa, polices in higher education are urging tertiary institutions to produce graduates who are socially responsible citizens. One method of achieving this is through service-learning initiatives. Zoos as community partners can provide exciting educational opportunities for students to do animal behaviour studies and to develop their social responsibility. A sample of 58 preservice life-sciences teachers from a South African university completed a questionnaire on their animal behaviour studies. This study sought to determine how animal behaviour studies could successfully be incorporated as a community service-learning project in a zoo setting, what the educational value of these studies was and what the benefits were of incorporating this community service-learning component in the life-sciences course. The incorporation of the service-learning component into the zoology course led to the students’ personal and professional development, knowledge about themselves, sensitivity to cultural diversity, civic responsibility and insights into the ways in which communities operate. For a successful service-learning project, lectures, students and community partners should all have a sense of engagement. A number of suggestions are made to improve the incorporation of this service-learning component into the existing zoology course.

    The Current GES DISC available services only allow user to select variables from a single dataset at a time and too many variables from a dataset are displayed, choice is hard. At American Geophysical Union (AGU) 2016 Fall Meeting, Goddard Earth Sciences Data Information Services Center (GES DISC) unveiled a new service: Datalist. A Datalist is a collection of predefined or user-defined data variables from one or more archived datasets. Our science support team curated predefined datalist and provided value to the user community. Imagine some novice user wants to study hurricane and typed in hurricane in the search box. The first item in the search result is GES DISC provided Hurricane Datalist. It contains scientists recommended variables from multiple datasets like TRMM, GPM, MERRA, etc. Datalist uses the same architecture as that of our new website, which also provides one-stop shopping for data, metadata, citation, documentation, visualization and other available services.We implemented Datalist with new GES DISC web architecture, one single web page that unified all user interfaces. From that webpage, users can find data by either type in keyword, or browse by category. It also provides user with a sophisticated integrated data and services package, including metadata, citation, documentation, visualization, and data-specific services, all available from one-stop shopping.

    Edema in palliative care patients is a common symptom, however, the research base for all aspects of its care is extremely poor. To evaluate a specialist palliative care edema service in order to report on the patient population referred, the types of edema encountered, and the causes of edema. Prior to study, three different edema types were described for evaluation: lymphedema, nonlymphatic edema, and a combination of the two. Retrospective chart evaluation was completed from August 2013 through January 2014. Patients with edema assessed by the specialist palliative care physiotherapy edema service. Sixty-three cases were included, comprising 10.5% of all new palliative care referrals during the study period. Ninety-two percent (n = 58) had a diagnosis of cancer and 57% (n = 36) were female. Age ranged from 45-97 years. The most common edema type was a mixed edema (46%, n = 29), followed by lymphedema (27%, n = 18) and nonlymphatic edema (16%, n = 10). Lymphorrhea occurred in 9.5% of cases. The most common reasons for edema, based on clinical opinion, were blocked lymphatics (33%) and dependency from immobility (27%). The most common site for edema was in the lower limbs (89%, n = 56). The time lapse from the last treatment to death ranged from 1-225 days. Having a mixed edema type or lymphorrhea was a relatively poor prognostic sign. This is the first study to describe in detail the occurrence of edema in palliative care patients. Edema may be present for many months prior to death making the search for effective treatments imperative.

    Fischer, Martin

    2012-12-01

    The article sheds light on psychological and work science aspects of the design and utilization of service robots. An initial presentation of the characteristics of man-robot interaction is followed by a discussion of the principles of the division of functions between human beings and robots in service area work systems. The following aspects are to be considered: (1) the organisation of societal work (such as the different employment and professional profiles of service employees), (2) the work tasks to be performed by humans and robots (such as handling, monitoring or decision-making tasks), (3) the possibilities and the limitations of realizing such tasks by means of information technology (depending, for example, on the motoric capabilities, perception and cognition of the robot). Consideration of these three design perspectives gives rise to criteria of usability. Current debate focuses on the (work science) principles of man-machine communication, though in future these should be supplemented with robot-specific criteria such as "motoric capabilities" or "relationship quality." The article concludes by advocating the convergence and combination of work science criteria with ideas drawn from participative design approaches in the development and utilization of service robots.

    2005-12-01

    Science teaching reforms of the past 10 to 20 years have focused on a pedagogical shift from verification-style laboratory exercises, toward hands-on and inquiry-based constructivist teaching methods. Such methods, however, require teachers to be proficient in more than just basic content and teaching strategies. To be effective teachers, these professionals must also be skilled in the design and implementation of research-style investigations. At Loyola College in Maryland, topics in the earth and environmental sciences are used as the basis for field research projects that teach our students science content, along with how to design age-appropriate investigative activities and how to implement them in a stimulating, inquiry-based learning environment. Presented here are examples of three projects, demonstrating how these themes are woven throughout our pre- and in-service teacher preparation programs, at both undergraduate and graduate levels. 1. Watershed Studies - In our undergraduate, pre-service, elementary education teacher preparation program, students design and implement a water quality study in a local watershed. In the classroom, students use topographic maps and aerial photographs to delineate the watersheds' boundaries, to identify current land use patterns, and to select appropriate locations on the trunk stream for testing. Water testing at these sites is conducted during field trips, with data analysis and interpretation performed on-site. On-site work allows students to make connections between stream water quality and adjacent land use practices. Students then relate the content and research results to science teaching standards, in order to develop a unit-plan for use in their future classrooms. 2. Land Use Assessment - In our graduate, in-service, elementary and middle school science program, a local stream valley is used as the basis for an analysis of potential land use changes. Students first construct a topographic base map of the area, and

    2011-12-01

    NASA's Earth Observing System Data and Information System (EOSDIS) is a core capability in NASA's Earth Science Data Systems Program. NASA's EOS ClearingHOuse (ECHO) is a metadata catalog for the EOSDIS, providing a centralized catalog of data products and registry of related data services. Working closely with the EOSDIS community, the ECHO team identified a need to develop the next generation EOS data and service discovery tool. This development effort relied on the following principles: + Metadata Driven User Interface - Users should be presented with data and service discovery capabilities based on dynamic processing of metadata describing the targeted data. + Integrated Data & Service Discovery - Users should be able to discovery data and associated data services that facilitate their research objectives. + Leverage Common Standards - Users should be able to discover and invoke services that utilize common interface standards. Metadata plays a vital role facilitating data discovery and access. As data providers enhance their metadata, more advanced search capabilities become available enriching a user's search experience. Maturing metadata formats such as ISO 19115 provide the necessary depth of metadata that facilitates advanced data discovery capabilities. Data discovery and access is not limited to simply the retrieval of data granules, but is growing into the more complex discovery of data services. These services include, but are not limited to, services facilitating additional data discovery, subsetting, reformatting, and re-projecting. The discovery and invocation of these data services is made significantly simpler through the use of consistent and interoperable standards. By utilizing an adopted standard, developing standard-specific adapters can be utilized to communicate with multiple services implementing a specific protocol. The emergence of metadata standards such as ISO 19119 plays a similarly important role in discovery as the 19115 standard

Journal of the Medical Library Association, 104(2, 109-117. http://dx.doi.org/10.3163/1536-5050.104.2.004 Abstract Objective – To compare the results of health sciences search queries in three web-scale discovery (WSD services for relevance, duplicate detection, and retrieval of MEDLINE content. Design – Comparative evaluation and bibliometric study. Setting – Six university libraries in the United States of America. Subjects – Three commercial WSD services: Primo, Summon, and EBSCO Discovery Service (EDS. Methods – The authors collected data at six universities, including their own. They tested each of the three WSDs at two data collection sites. However, since one of the sites was using a legacy version of Summon that was due to be upgraded, data collected for Summon at this site were considered obsolete and excluded from the analysis. The authors generated three questions for each of six major health disciplines, then designed simple keyword searches to mimic typical student search behaviours. They captured the first 20 results from each query run at each test site, to represent the first “page” of results, giving a total of 2,086 total search results. These were independently assessed for relevance to the topic. Authors resolved disagreements by discussion, and calculated a kappa inter-observer score. They retained duplicate records within the results so that the duplicate detection by the WSDs could be compared. They assessed MEDLINE coverage by the WSDs in several ways. Using precise strategies to generate a relevant set of articles, they conducted one search from each of the six disciplines in PubMed so that they could compare retrieval of MEDLINE content. These results were cross-checked against the first 20 results from the corresponding query in the WSDs. To aid investigation of overall

    Full Text Available Coleoptera is a group of insects that are most diverse among insect resources. Although used as indicator species and applied in developing new drugs, it is difficult to identify them quickly. Since the development of a method using mitochondrial DNA information for identification, studies have been conducted in Korea to swiftly and accurately identify species. The National Science Museum of Korea (NSMK has been collecting and morphologically identifying domestic reference insects since 2013, and building a database of DNA barcodes with digital images. The NSMK completed construction of a database of digital images and DNA barcodes of 60 beetle species in the Korean National Research Information System. A total of 179 specimens and 60 species were used for the analysis, and the averages of intraspecific and interspecific variations were 0.70±0.45% and 26.34±6.01%, respectively, with variation rates ranging from 0% to 1.45% and 9.83% to 56.23%, respectively.

    2016-04-01

    The European Plate Observing System (EPOS) aims to create a pan-European infrastructure for solid Earth science to support a safe and sustainable society. The main vision of the European Plate Observing System (EPOS) is to address the three basic challenges in Earth Sciences: (i) unravelling the Earth's deformational processes which are part of the Earth system evolution in time, (ii) understanding the geo-hazards and their implications to society, and (iii) contributing to the safe and sustainable use of geo-resources. The mission of EPOS is to monitor and understand the dynamic and complex Earth system by relying on new e-science opportunities and integrating diverse and advanced Research Infrastructures in Europe for solid Earth Science. EPOS will enable innovative multidisciplinary research for a better understanding of the Earth's physical and chemical processes that control earthquakes, volcanic eruptions, ground instability and tsunami as well as the processes driving tectonics and Earth's surface dynamics. EPOS will improve our ability to better manage the use of the subsurface of the Earth. Through integration of data, models and facilities EPOS will allow the Earth Science community to make a step change in developing new concepts and tools for key answers to scientific and socio-economic questions concerning geo-hazards and geo-resources as well as Earth sciences applications to the environment and to human welfare. EPOS has now started its Implementation Phase (EPOS-IP). One of the main challenges during the implementation phase is the integration of multidisciplinary data into a single e-infrastructure. Multidisciplinary data are organized and governed by the Thematic Core Services (TCS) and are driven by various scientific communities encompassing a wide spectrum of Earth science disciplines. These include Data, Data-products, Services and Software (DDSS), from seismology, near fault observatories, geodetic observations, volcano observations

    2016-04-01

    EPOS has been designed with the vision of creating a pan-European infrastructure for solid Earth science to support a safe and sustainable society. In accordance with this scientific vision, the EPOS mission is to integrate the diverse and advanced European Research Infrastructures for solid Earth science relying on new e-science opportunities to monitor and unravel the dynamic and complex Earth System. EPOS will enable innovative multidisciplinary research for a better understanding of the Earth's physical and chemical processes that control earthquakes, volcanic eruptions, ground instability and tsunami as well as the processes driving tectonics and Earth's surface dynamics. To accomplish its mission, EPOS is engaging different stakeholders, not limited to scientists, to allow the Earth sciences to open new horizons in our understanding of the planet. EPOS also aims at contributing to prepare society for geo-hazards and to responsibly manage the exploitation of geo-resources. Through integration of data, models and facilities, EPOS will allow the Earth science community to make a step change in developing new concepts and tools for key answers to scientific and socio-economic questions concerning geo-hazards and geo-resources as well as Earth sciences applications to the environment and human welfare. A long-term integration plan is necessary to accomplish the EPOS mission. EPOS is presently in its implementation phase further extending its pan-European dimension. The EPOS Implementation Phase builds on the achievements of the successful EPOS Preparatory Phase project and consists of two key activities: the legal establishment of the EPOS-ERIC and the EPOS IP project. The EPOS implementation phase will last from 2015 to 2019. Key objectives of the project are: implementing Thematic Core Services (TCS), the domain-specific service hubs for coordinating and harmonizing national resources/plans with the European dimension of EPOS; building the Integrated Core

    University of Delaware faculty in the geological sciences, biological sciences, and the physics and astronomy departments have partnered with faculty and researchers from the school of education to form a continuum for K- 8 pre-service teacher preparation in science. The goal of the continuum is to develop integrated understandings of content and pedagogy so that these future teachers can effectively use inquiry-based approaches in teaching science in their classrooms. Throughout the continuum where earth science content appears an earth system science approach, with emphasis on inquiry-based activities, is employed. The continuum for K-8 pre-service teachers includes a gateway content course in the earth, life, or physical sciences taken during the freshman year followed by integrated science content and methods courses taken during the sophomore year. These integrated courses, called the Science Semester, were designed and implemented with funding from the National Science Foundation. During the Science Semester, traditional content and pedagogy subject matter boundaries are crossed to stress shared themes that teachers must understand to teach standards-based science. Students work collaboratively on multidisciplinary problem-based learning (PBL) activities that place science concepts in authentic contexts and build learning skills. They also critically explore the theory and practice of elementary science teaching, drawing on their shared experiences of inquiry learning during the Science Semester. The PBL activities that are the hallmark of the Science Semester provide the backdrop through which fundamental earth system interactions can be studied. For example in a PBL investigation that focuses on kids, cancer, and the environment, the hydrologic cycle with emphasis on surface runoff and ground water contamination is studied. Those students seeking secondary certification in science will enroll, as a bridge toward their student teaching experience, in an

    Full Text Available Introduction & Objective: In recent years mental health attracts attention of many researchers, and severe emotional stress that can interfere in creation of different organic diseases is one of the most prominent of this aspects. Sudden hearing loss (S.H.L. is one of these disorders that could followed after stress and eventually may heal completely, relatively or lead to permanent deafness. S.H.L. could influence on interpersonal relationships and in this way could change quality of life negatively, so enough and appropriate attention is necessary. In this research by determination of level of stress we intended to study relationship between mental health and incidence of S.H.L.Materials & Methods: In this case – control study 65 patients that referred to otolaryngology services of Hamadan during 2005-2006 with S.H.L. (case group compared to 89 healthy subjects (control group. Control group were free from any systemic diseases and were matched from sex and age aspects to the case group. In case group after complete audiometric evaluation and confirmation of S.H.L, stress level was assessed using GHQ-28 questionnaire. This questionnaire contained 28 questions in 4 different fields: somatic symptoms, anxiety and insomnia, social problems and depression. Linkert scoring method was used for scoring of questionnaires and all data were analyzed using T-Test and chi-square test.Results: During 4 months incidence of S.H.L. in referred patients were 5.1%, significant statistical relationships between S.H.L. and level of stress (P<0.001 and severity of hearing loss and level of stress (P<0.05, r =0.34 were found. The most common audiometric pattern was downward slopping pattern (56.92%. Evaluation of level of stress between two sex groups did not show any significant difference (P<0.05.Conclusion: Stress can be known as one of the predisposing factors of S.H.L. and may be possible to control by paying more attention to the role of self-awareness and

    To determine age- and sex-specific reference intervals for 10 health examination items in Japanese adults. Health examination data were accumulated from 24 different prefectural health service associations affiliated with the Japan Association of Health Service. Those who were non-smokers, drank less than 7 days/week, and had a body mass index of 18.5-24.9kg/m2 were sampled as a reference population (n = 737,538; 224,947 men and 512,591 women). After classified by age and sex, reference intervals for 10 health examination items (systolic blood pressure, diastolic blood pressure, total cholesterol, triglyceride, glucose, uric acid, AST, ALT, gamma-GT, and hemoglobin) were estimated using the parametric and nonparametric methods. In every item except for hemoglobin, men had higher reference intervals than women. Systolic blood pressure, total cholesterol, and glucose showed an upward trend in values with increasing age. Hemoglobin showed a downward trend in values with increasing age. Triglyceride, ALT, and gamma-GT reached a peak in middle age. Overall, parametric estimates showed narrower reference intervals than non-parametric estimates. Reference intervals vary with age and sex. Age- and sex-specific reference intervals may contribute to better assessment of health examination data.

    This study explored pre-service secondary science teachers' perceptions of classroom emotional climate in the context of the Bhutanese macro-social policy of Gross National Happiness. Drawing upon sociological perspectives of human emotions and using Interaction Ritual Theory this study investigated how pre-service science teachers may be supported in their professional development. It was a multi-method study involving video and audio recordings of teaching episodes supported by interviews and the researcher's diary. Students also registered their perceptions of the emotional climate of their classroom at 3-minute intervals using audience response technology. In this way, emotional events were identified for video analysis. The findings of this study highlighted that the activities pre-service teachers engaged in matter to them. Positive emotional climate was identified in activities involving students' presentations using video clips and models, coteaching, and interactive whole class discussions. Decreases in emotional climate were identified during formal lectures and when unprepared presenters led presentations. Emotions such as frustration and disappointment characterized classes with negative emotional climate. The enabling conditions to sustain a positive emotional climate are identified. Implications for sustaining macro-social policy about Gross National Happiness are considered in light of the climate that develops in science teacher education classes.

    NASA science and engineering efforts rely heavily on compute and data handling systems. The nature of NASA science data is such that it is not restricted to NASA users, instead it is widely shared across a globally distributed user community including scientists, educators, policy decision makers, and the public. Therefore NASA science computing is a candidate use case for cloud computing where compute resources are outsourced to an external vendor. Amazon Web Services (AWS) is a commercial cloud computing service developed to use excess computing capacity at Amazon, and potentially provides an alternative to costly and potentially underutilized dedicated acquisitions whenever NASA scientists or engineers require additional data processing. AWS desires to provide a simplified avenue for NASA scientists and researchers to share large, complex data sets with external partners and the public. AWS has been extensively used by JPL for a wide range of computing needs and was previously tested on a NASA Agency basis during the Nebula testing program. Its ability to support the Langley Science Directorate needs to be evaluated by integrating it with real world operational needs across NASA and the associated maturity that would come with that. The strengths and weaknesses of this architecture and its ability to support general science and engineering applications has been demonstrated during the previous testing. The Langley Office of the Chief Information Officer in partnership with the Atmospheric Sciences Data Center (ASDC) has established a pilot business interface to utilize AWS cloud computing resources on a organization and project level pay per use model. This poster discusses an effort to evaluate the feasibility of the pilot business interface from a project level perspective by specifically using a processing scenario involving the Clouds and Earth's Radiant Energy System (CERES) project.

    integrating RI elements. This integration requires a significant coordination between, among others, disciplinary (thematic) communities, national RIs policies and initiatives, as well as geo- and IT-scientists. The RIs that EPOS is coordinating include: i) regionally-distributed geophysical observing systems (seismological and geodetic networks); ii) local observatories (including geomagnetic, near-fault and volcano observatories); iii) analytical and experimental laboratories; iv) integrated satellite data and geological information services v) new services for natural and anthropogenic hazards. Here we present the successful story of the EPOS Preparatory Phase and the progress towards the implementation of both integrated core services (ICS) and thematic core services (TCS) for the different communities participating to the integration plan. We aim to discuss the achieved results and the approach followed to design the implementation phase. The goal is to present and discuss the strategies adopted to foster the implementation of TCS, clarifying their crucial role as domain-specific service hubs for coordinating and harmonizing national resources/plans with the European dimension of EPOS, and their integration to develop the new ICS. We will present the prototype of the ICS central hub as a key contribution for providing multidisciplinary services for solid Earth sciences as well as the glue to keep ICT aspects integrated and rationalized across EPOS. Finally, we will discuss the well-defined role of the EPOS-ERIC Headquarter to coordinate and harmonize national RIs and EPOS services (through ICS and TCS) looking for an effective commitment by national governments. It will be an important and timely opportunity to discuss the EPOS roadmap toward the operation of the novel multidisciplinary platform for discoveries to foster scientific excellence in solid Earth sciences.

  12. The Development of Interdisciplinary Teaching Approaches among Pre-service Science and Mathematics Teachers

    Science.gov (United States)

    Miranda Martins, Dominique

    This study sought to understand how a group of pre-service teachers in a combined secondary science and mathematics teaching methods course conceptualized and experienced interdisciplinary approaches to teaching. Although knowing how to plan interdisciplinary activities is an essential teaching practice in Quebec, these pre-service teachers faced many challenges during the process of learning to teach with this approach. By using two interdisciplinary frameworks (Nikitina, 2005; Boix Mansilla & Duraising, 2007), I qualitatively analyzed the development of the pre-service teachers' prior and emerging ideas about interdisciplinarity and their ability to plan interdisciplinary teaching activities. The provincial curriculum and issues related to time greatly shaped students' conceptions about interdisciplinarity in the classroom and constrained their ability to plan for and envision the enactment of interdisciplinary lessons in secondary science and mathematics classes. In addition, images of themselves as content-specialists, self-efficacy beliefs in relation to interdisciplinary teaching, and student learning as a source of teacher motivation emerged as key factors promoting or interrupting the development of interdisciplinary teaching approaches. Examination of these factors highlights the need for teacher-education programs to provide opportunities for pre-service teachers to explore how they see themselves as educators, increase their instructional self-efficacy beliefs, and motivate them to teach in an interdisciplinary fashion. Keywords: interdisciplinary teaching, student-teachers, curriculum, teacher-education program, self-efficacy, motivation.

    2016-01-01

    The Earth and Space Science Partnership (ESSP) is a collaboration among Penn State scientists, science educators and seven school districts across Pennsylvania. One of the ESSP goals has been to provide pre-service teachers with new or improved science course offerings at Penn State in the Earth and Space Science domains. In particular, we aim to provide students with opportunities to learn astronomy content knowledge through teaching methods that engage them in investigations where they experience the practices used by astronomers. We have designed a new course that builds on our research into students' ideas about Solar System astronomy (Plummer et al. 2015) and the curriculum our team created for a professional development workshop for in-service teachers (Palma et al. 2013) with this same theme. The course was offered for the first time in the spring 2015 semester. We designed the course using a coherent science content storyline approach (see, e.g., Palma et al. 2014), which requires all of the student investigations to build towards a big idea in science; in this case, we chose the model for formation of our Solar System. The course led pre-service teachers through a series of investigations that model the type of instruction we hope they will adopt in their own classrooms. They were presented with a series of research questions that all tie in to the big idea of Solar System formation, and they were responsible for collecting and interpreting their own data to draw evidence-based conclusions about one aspect of this model. Students in the course were assessed on their astronomy content knowledge, but also on their ability to construct arguments using scientific reasoning to answer astronomy questions. In this poster, we will present descriptions of the investigations, the assessments used, and our preliminary results about how the course led this group of pre-service teachers to improved understanding of astronomy content and the practices astronomers use in

    Scientists working on ecosystem service (ES) science are engaged in a mission-driven discipline. They can contribute to science-policy interfaces where knowledge is co-produced and used. How scientists engage with the governance arena to mobilise their knowledge remains a matter of personal choice, influenced by individual values. ES science cannot be considered neutral and a discussion of the values that shape it forms an important part of the sustainability dialogue. We propose a simple decision tree to help ES scientists identify their role and the purpose of the knowledge they produce. We characterise six idealised scientific postures spanning possible roles at the science-policy interface (pure scientist, science arbiter-guarantor, issue advocate-guardian, officer, honest broker and stealth issue advocate) and illustrate them with feedbacks from interviews. We encourage ES scientists to conduct a reflexive exploration of their attitudes regarding knowledge production and use, with the intention of progressing toward a higher recognition of the political and ethical importance of ES assessments.

    Several studies indicate that homosexual males have a high proportion of older brothers compared to heterosexual males. Natal males with gender dysphoria who are likely to be homosexual also display this sibship pattern. Until recently, there was little evidence linking homosexuality and/or gender dysphoria in females to unique sibship characteristics. Two studies have indicated that natal female youth clinically referred for gender dysphoria are more likely to be only children (Schagen, Delemarre-van de Waal, Blanchard, & Cohen-Kettenis, 2012; VanderLaan, Blanchard, Wood, & Zucker, 2014). However, these studies did not include control groups of youth clinically referred for other reasons. Thus, it is unclear whether the increased likelihood of only-child status is specific to gender-referred natal females. This study compared only-child status among youth referred to a mental health service for gender dysphoria (778 males, 245 females) versus other reasons (783 males, 281 females). Prehomosexual gender-referred males were less likely to be only children than clinical controls. Contrary to previous findings, gender-referred females were not more likely to be only children, indicating that increased likelihood of only-child status is not specific to gender-referred females, but is characteristic of clinic-referred females more generally.

    Globus is software-as-a-service for research data management, developed at, and operated by, the University of Chicago. Globus, accessible at www.globus.org, provides high speed, secure file transfer; file sharing directly from existing storage systems; and data publication to institutional repositories. 40,000 registered users have used Globus to transfer tens of billions of files totaling hundreds of petabytes between more than 10,000 storage systems within campuses and national laboratories in the US and internationally. Web, command line, and REST interfaces support both interactive use and integration into applications and infrastructures. An important component of the Globus system is its foundational identity and access management (IAM) platform service, Globus Auth. Both Globus research data management and other applications use Globus Auth for brokering authentication and authorization interactions between end-users, identity providers, resource servers (services), and a range of clients, including web, mobile, and desktop applications, and other services. Compliant with important standards such as OAuth, OpenID, and SAML, Globus Auth provides mechanisms required for an extensible, integrated ecosystem of services and clients for the research and education community. It underpins projects such as the US National Science Foundation's XSEDE system, NCAR's Research Data Archive, and the DOE Systems Biology Knowledge Base. Current work is extending Globus services to be compliant with FEDRAMP standards for security assessment, authorization, and monitoring for cloud services. We will present Globus IAM solutions and give examples of Globus use in various projects for federated access to resources. We will also describe how Globus Auth and Globus research data management capabilities enable rapid development and low-cost operations of secure data sharing platforms that leverage Globus services and integrate them with local policy and security.

    It has been said, "The two greatest forces in human history are science and religion" (Schachter-Shalomi & Smith, 1999, p. 220). It is those forces and their influence on science teaching that motivated the focus of this study to explore the cultural referents of elementary teachers and the place of fundamentalist Southern Baptist religious beliefs in teaching elementary science. Through a hermeneutic phenomenological framework, multiple case study method was used to interpret the individual consciousness and classroom lived experiences of three elementary teachers. The particularities surrounding elementary science instruction by devout Southern Baptist teachers was explored through several data sources, which included: personal interactions with the teachers, classroom observations, journaling, and interviews (Stake, 1995; Yin, 2003). Insights gained from this study indicate that the religious component of the culture of elementary teachers affects science teaching and learning. In Alabama, Southern Baptist beliefs influence both the public and private lives of educators. Replicated themes revealed the following themes: (a) a lack of concern for occasionally mentioning God in class due to the conservatively religious nature of Southern culture, (b) the teachers' beliefs affected classroom instruction and student interaction, (c) a commitment to science teaching in the context of the elementary classrooms, and (d) the teachers' as mediators. In addition, the theoretical framework provided an awareness of how the lives of the three educators could yield replicated themes. Indications are for a better understanding of how religion, as part of culture, influences science classroom instruction, including teacher education programs and aspects of science teaching and learning.
