    The Electronic Caseload Analysis Tool (eCAT) is a knowledge-based software tool to assist the caseload analysis process. The tool provides a wide range of graphical reports, along with an integrated clinical advisor, to assist district nurses, team leaders, operational and strategic managers with caseload analysis by describing, comparing and benchmarking district nursing practice in the context of population need, staff resources, and service structure. District nurses and clinical lead nurses in Northern Ireland developed the tool, along with academic colleagues from the University of Ulster, working in partnership with a leading software company. The aim was to use the eCAT tool to identify the nursing need of local populations, along with the variances in district nursing practice, and match the workforce accordingly. This article reviews the literature, describes the eCAT solution and discusses the impact of eCAT on nursing practice, staff allocation, service delivery and workforce planning, using fictitious exemplars and a post-implementation evaluation from the trusts.

    This study develops a methodology for rapidly obtaining approximate estimates of the economic consequences from numerous natural, man-made and technological threats. This software tool is intended for use by various decision makers and analysts to obtain estimates rapidly. It is programmed in Excel and Visual Basic for Applications (VBA) to facilitate its use. This tool is called E-CAT (Economic Consequence Analysis Tool) and accounts for the cumulative direct and indirect impacts (including resilience and behavioral factors that significantly affect base estimates) on the U.S. economy. E-CAT is intended to be a major step toward advancing the current state of economic consequence analysis (ECA) and also contributing to and developing interest in further research into complex but rapid turnaround approaches. The essence of the methodology involves running numerous simulations in a computable general equilibrium (CGE) model for each threat, yielding synthetic data for the estimation of a single regression equation based on the identification of key explanatory variables (threat characteristics and background conditions). This transforms the results of a complex model, which is beyond the reach of most users, into a "reduced form" model that is readily comprehensible. Functionality has been built into E-CAT so that its users can switch various consequence categories on and off in order to create customized profiles of economic consequences of numerous risk events. E-CAT incorporates uncertainty on both the input and output side in the course of the analysis.

    1997-12-01

    Full Text Available Electronic channels are rapidly taking off as a means of accessing journal literature (Lancaster, 1995. Behind the interest lies the increasing concern of academic libraries with the mounting cost of purchasing printed journals. Some commentators believe that higher-education institutions themselves will move into the electronic publishing field in order to control expenditure on journals (Okerson and O'Donnell, 1995. This rapid growth in the number of electronic journals available raises the immediate question - how will all those concerned with journals, as authors, editors, or readers, be trained? The prime purpose of the project described here is to explore the problems of providing such training. It was also planned that student feedback would assist the construction of an online teaching package.

    Full Text Available AbstractConsidering the fact that the number of publications available online only is growing, the question whether to include online electronic resources into the Slovenian bibliography, and if so, in which way, and what are the requirements for the inclusion, is raised. To answer these questions, the research on the growth of the Slovenian online scientific production in comparison with production in printed form was conducted in the case of original scientific articles. Results showed a rapid growth of the number of original scientific articles available online only, which indicates the necessity to form a separate Slovenian bibliography of online resources. The selection criteria for the Slovenian bibliography of online resources are also presented. This kind of bibliography would, along with the informational value, add to the historical value of intellectual production in a given time frame, enriched with a link to the resource preserved in another location (archive, repository, in case of unavailability of the resource on its original location.

  13. On the Nuclear Mechanisms Underlying the Heat Production by the E-Cat

    CERN Document Server

    Cook, Norman D

    2015-01-01

    We discuss the isotopic abundances found in the E-Cat reactor with regard to the nuclear mechanisms responsible for excess heat. We argue that a major source of energy is a reaction between the first excited-state of 7Li4 and a proton, followed by the breakdown of 8Be4 into two alphas with high kinetic energy, but without gamma radiation. The unusual property of the 7Li4 isotope that allows this reaction is similar to the property that underlies the Mossbauer effect: the presence of unusually low-lying excited states in stable, odd-Z and/or odd-N nuclei. We use the lattice version of the independent-particle model (IPM) of nuclear theory to show how the geometrical structure of isotopes indicate nuclear reactions that are not predicted in the conventional version of the IPM. Finally, we speculate on similar mechanisms that may be involved in other low-energy nuclear reactions (LENR).

  14. ECAT11/L1td1 is enriched in ESCs and rapidly activated during iPSC generation, but it is dispensable for the maintenance and induction of pluripotency.

    Directory of Open Access Journals (Sweden)

    Kumiko A Iwabuchi

    Full Text Available The principal factors that lead to proliferation and pluripotency in embryonic stem cells (ESCs have been vigorously investigated. However, the global network of factors and their full signaling cascade is still unclear. In this study, we found that ECAT11 (L1td1 is one of the ESC-associated transcripts harboring a truncated fragment of ORF-1, a component of the L1 retrotransposable element. We generated an ECAT11 knock-in mouse by replacing its coding region with green fluorescent protein. In the early stage of development, the fluorescence was observed at the inner cell mass of blastocysts and epiblasts. Despite this specific expression, ECAT11-null mice grow normally and are fertile. In addition, ECAT11 was dispensable for both the proliferation and pluripotency of ESCs.We found rapid and robust activation of ECAT11 in fibroblasts after the forced expression of transcription factors that can give rise pluripotency in somatic cells. However, iPS cells could be established from ECAT11-null fibroblasts. Our data demonstrate the dispensability of ECAT11/L1td1 in pluripotency, despite its specific expression.

    Cobb, Nathan K; Brookover, Jody; Cobb, Caroline O

    2015-03-01

    Electronic nicotine delivery systems (ENDS) are growing in awareness and use in the USA. They are currently unregulated as the Food and Drug Administration has yet to assert jurisdiction under its tobacco authority over these products, and a US Court of Appeals held they cannot be regulated as drugs/delivery devices if they are not marketed for a therapeutic purpose. Observation of the current online marketplace suggests ENDS, like some nutraceutical products, are being promoted using affiliate marketing techniques using claims concerning purported health benefits. This study performed a forensic analysis to characterise the relationships between online ENDS affiliate advertisements and ENDS sellers, and evaluated descriptive content on advertisements and websites to inform future policy and regulatory efforts. A purposive sampling strategy was used to identify three forms of ENDS advertising. Web proxy software recorded identifiable objects and their ties to each other. Network analysis of these ties followed, as well as analysis of descriptive content on advertisements and websites identified. The forensic analysis included four ENDS advertisements, two linked affiliate websites, and two linked seller websites, and demonstrated a multilevel relationship between advertisements and sellers with multiple layers of redirection. Descriptive analysis indicated that advertisements and affiliates, but not linked sellers, included smoking cessation claims. Results suggest that ENDS sellers may be trying to distance marketing efforts containing unsubstantiated claims from sales. A separate descriptive analysis of 20 ENDS seller web pages indicated that the use of affiliate marketing by sellers may be widespread. These findings support increased monitoring and regulation of ENDS marketing to prevent deceptive marketing tactics and ensure consumer safety. Published by the BMJ Publishing Group Limited.

    Motivating tobacco consumers to change their behavior, and harm reduction strategies, are the predominant traditional approaches to tobacco cessation. Recent trends worldwide have shown the emergence of Electronic Nicotine Delivery Systems (ENDS), such as electronic cigarettes (e-cigarettes), as a purported harm reduction strategy to traditional cigarettes. Considering the global rise in the popularity of ENDS, our study aims to survey the online retail market for ENDS in India. The current study was conducted in September-October, 2015 and 4 keywords were used to search Google India to identify online retail websites marketing ENDS. Each website was searched using the same keywords and all specific website pages displaying ENDS models were considered. Thus, data was obtained for various measures of ENDS present on the model descriptions. A total of 6 retail shopping websites were searched which revealed 65 different models of ENDS (34 brands). Forty-five models (69%) were flavored and 21 models (33%) mentioned about nicotine strengths. Seventeen models (26%) provided health warnings in their product descriptions. "No tar no tobacco" was most common claim accounting to 34 models (51%). This article provide insight into the current status of evident online sales of ENDS in India. There is urgent need to implement regulations on online sales of these products and protect the future from such approaches of tobacco control which still have divided opinions. The study permits the use of web search engine to explore market availability of ENDS at various online retail websites. Recommendations from the study can be used to guide policy makers in developing strategies tailored to regulate availability and online sales of ENDS in India.

    Online access to medical records and linked services, including requesting repeat prescriptions and booking appointments, enables patients to personalize their access to care. However, online access creates opportunities and challenges for both health professionals and their patients, in practices and in research. The challenges for practice are the impact of online services on workload and the quality and safety of health care. Health professionals are concerned about the impact on workload, especially from email or other online enquiry systems, as well as risks to privacy. Patients report how online access provides a convenient means through which to access their health provider and may offer greater satisfaction if they get a timely response from a clinician. Online access and services may also result in unforeseen consequences and may change the nature of the patient-clinician interaction. Research challenges include: (1) Ensuring privacy, including how to control inappropriate carer and guardian access to medical records; (2) Whether online access to records improves patient safety and health outcomes; (3) Whether record access increases disparities across social classes and between genders; and (4) Improving efficiency. The challenges for practice are: (1) How to incorporate online access into clinical workflow; (2) The need for a business model to fund the additional time taken. Creating a sustainable business model for a safe, private, informative, more equitable online service is needed if online access to records is to be provided outside of pay-for-service systems.

    2004-01-01

    Full Text Available This paper outlines the architecture for an online assessment management system implemented at the University of Southern Queensland. The system assists teams of academics in the management and marking of electronically submitted student assignments in large-scale classes. The system designed to provide a flexible yet structured method for providing feedback to students also offers semi-automatic file handling and grade recording. The system, Classmate, allows a team of markers to access and mark student assignments through a web interface designed to parallel paper-based marking systems. An online authoring tool replaces the red pen on paper analogy. A pilot study conducted on the use of Classmate has found the system to be of use in providing students with consistent feedback, allowing traditional assignment interactions and reducing trivial and repetitive assignment marking tasks.

    In cardiac tissue engineering approaches to treat myocardial infarction, cardiac cells are seeded within three-dimensional porous scaffolds to create functional cardiac patches. However, current cardiac patches do not allow for online monitoring and reporting of engineered-tissue performance, and do not interfere to deliver signals for patch activation or to enable its integration with the host. Here, we report an engineered cardiac patch that integrates cardiac cells with flexible, free-standing electronics and a 3D nanocomposite scaffold. The patch exhibited robust electronic properties, enabling the recording of cellular electrical activities and the on-demand provision of electrical stimulation for synchronizing cell contraction. We also show that electroactive polymers containing biological factors can be deposited on designated electrodes to release drugs in the patch microenvironment on-demand. We expect that the integration of complex electronics within cardiac patches will eventually provide therapeutic control and regulation of cardiac function. PMID:26974408

    Peris, Miguel; Escuder-Gilabert, Laura

    2013-12-04

    Fermentation processes are often sensitive to even slight changes of conditions that may result in unacceptable end-product quality. Thus, close follow-up of this type of processes is critical for detecting unfavorable deviations as early as possible in order to save downtime, materials and resources. Nevertheless the use of traditional analytical techniques is often hindered by the need for expensive instrumentation and experienced operators and complex sample preparation. In this sense, one of the most promising ways of developing rapid and relatively inexpensive methods for quality control in fermentation processes is the use of chemical multisensor systems. In this work we present an overview of the most important contributions dealing with the monitoring of fermentation processes using electronic noses and electronic tongues. After a brief description of the fundamentals of both types of devices, the different approaches are critically commented, their strengths and weaknesses being highlighted. Finally, future trends in this field are also mentioned in the last section of the article.

    To ascertain the rate, type, significance, trends and the potential risk factors associated with radiotherapy incidents in a large academic department. Data for all radiotherapy activities from July 2001 to January 2011 were reviewed from radiotherapy incident reporting forms. Patient and treatment data were obtained from the radiotherapy record and verification database (MOSAIQ) and the patient database (HOSPRO). Logistic regression analyses were performed to determine variables associated with radiotherapy incidents. In that time, 65,376 courses of radiotherapy were delivered with a reported incident rate of 2.64 per 100 courses. The rate of incidents per course increased (1.96 per 100 courses to 3.52 per 100 courses, p5% deviation in dose (10.50 to 2.75%, p<0.001) had decreased after the introduction of an online electronic reporting system. The following variables were associated with an increased rate of incidents: afternoon treatment time, paediatric patients, males, inpatients, palliative plans, head-and-neck, skin, sarcoma and haematological malignancies. In general, complex plans were associated with higher incidence rates. Radiotherapy incidents were infrequent and most did not result in significant dose deviation. A number of risk factors were identified and these could be used to highlight high-risk cases in the future. Introduction of an online electronic reporting system resulted in a significant increase in the number of incidents being reported. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

    Hua, My; Alfi, Mina; Talbot, Prue

    2013-04-08

    The health effects caused by electronic cigarette (e-cigarette) use are not well understood. Our purpose was to document the positive and negative short-term health effects produced by e-cigarette use through an analysis of original posts from three online e-cigarettes forums. Data were collected into Microsoft Access databases and analyzed using Cytoscape association graphics, frequency distributions, and interactomes to determine the number and type of health effects reported, the organ systems affected the frequency of specific effects, and systems interactions. A total of 405 different symptoms due to e-cigarette use were reported from three forums. Of these, 78 were positive, 326 were negative, and one was neutral. While the reported health effects were similar in all three forums, the forum with the most posts was analyzed in detail. Effects, which were reported for 12 organ systems/anatomical regions, occurred most often in the mouth and throat and in the respiratory, neurological, sensory, and digestive systems. Users with negative symptoms often reported more than one symptom, and in these cases interactions were often seen between systems, such as the circulatory and neurological systems. Positive effects usually occurred singly and most frequently affected the respiratory system. This is the first compilation and analysis of the health effects reported by e-cigarette users in online forums. These data show that e-cigarette use can have wide ranging positive and negative effects and that online forums provide a useful resource for examining how e-cigarette use affects health.

    Full Text Available The present investigation attempts to find out the present status quo by studying the strength and weakness of websites of online electronic journals for children and adolescents. By comparing them, it intends to provide a model for optimal use and more pragmatic design. Both library and evaluative research methods were employed. The latter was carried out using descriptive and inferential statistics. An evaluation form based on five factors of content, visual design structure, technical structure and copyright and operational indicators was used as the primary data collection instruments. Each in turn were composed of 62 sub-indicators. SPSS statistical software was used. The study found that the current fourteen journal websites lack the required effectiveness, ranging from unsuitable to totally inappropriate. The findings further indicated that the website designers for children and adolescent magazines do not pay the necessary attention to website design based on the aforementioned five factors.

    Objective The aim of the present study was to audit the current use of medical records to determine completeness and concordance with other sources of medical information.Methods Medical records for 40 patients from each of five Melbourne major metropolitan hospitals were randomly selected (n=200). A quantitative audit was performed for detailed patient information and medical record keeping, as well as data collection, storage and utilisation. Using each hospital's current online clinical database, scanned files and paperwork available for each patient audited, the reviewers sourced as much relevant information as possible within a 30-min time allocation from both the record and the discharge summary.Results Of all medical records audited, 82% contained medical and surgical history, allergy information and patient demographics. All audited discharge summaries lacked at least one of the following: demographics, medication allergies, medical and surgical history, medications and adverse drug event information. Only 49% of records audited showed evidence the discharge summary was sent outside the institution.Conclusions The quality of medical data captured and information management is variable across hospitals. It is recommended that medical history documentation guidelines and standardised discharge summaries be implemented in Australian healthcare services.What is known about this topic? Australia has a complex health system, the government has approved funding to develop a universal online electronic medical record system and is currently trialling this in an opt-out style in the Napean Blue Mountains (NSW) and in Northern Queensland. The system was originally named the personally controlled electronic health record but has since been changed to MyHealth Record (2016). In Victoria, there exists a wide range of electronic health records used to varying degrees, with some hospitals still relying on paper-based records and many using scanned medical records. This

    Growth of Internet gambling has fuelled concerns about its contribution to gambling problems. However, most online gamblers also gamble on land-based forms, which may be the source of problems for some. Studies therefore need to identify the problematic mode of gambling (online or offline) to identify those with an online gambling problem. Identifying most problematic form of online gambling (e.g., EGMs, race betting, sports betting) would also enable a more accurate examination of gambling problems attributable to a specific online gambling form. This study pursued this approach, aiming to: (1) determine demographic, behavioral and psychological risk factors for gambling problems on online EGMs, online sports betting and online race betting; (2) compare the characteristics of problematic online gamblers on each of these online forms. An online survey of 4,594 Australian gamblers measured gambling behavior, most problematic mode and form of gambling, gambling attitudes, psychological distress, substance use, help-seeking, demographics and problem gambling status. Problem/moderate risk gamblers nominating an online mode of gambling as their most problematic, and identifying EGMs (n = 98), race betting (n = 291) or sports betting (n = 181) as their most problematic gambling form, were compared to non-problem/low risk gamblers who had gambled online on these forms in the previous 12 months (n = 64, 1145 and 1213 respectively), using bivariate analyses and then logistic regressions. Problem/moderate risk gamblers on each of these online forms were then compared. Risk factors for online EGM gambling were: more frequent play on online EGMs, substance use when gambling, and higher psychological distress. Risk factors for online sports betting were being male, younger, lower income, born outside of Australia, speaking a language other than English, more frequent sports betting, higher psychological distress, and more negative attitudes toward gambling.

    A portable electronic nose with database connection for on-line classification of pollutants in water is presented in this paper. It is a hand-held, lightweight and powered instrument with wireless communications capable of standalone operation. A network of similar devices can be configured for distributed measurements. It uses four resistive microsensors and headspace as sampling method for extracting the volatile compounds from glass vials. The measurement and control program has been developed in LabVIEW using the database connection toolkit to send the sensors data to a server for training and classification with Artificial Neural Networks (ANNs). The use of a server instead of the microprocessor of the e-nose increases the capacity of memory and the computing power of the classifier and allows external users to perform data classification. To address this challenge, this paper also proposes a web-based framework (based on RESTFul web services, Asynchronous JavaScript and XML and JavaScript Object Notation) that allows remote users to train ANNs and request classification values regardless user's location and the type of device used. Results show that the proposed prototype can discriminate the samples measured (Blank water, acetone, toluene, ammonia, formaldehyde, hydrogen peroxide, ethanol, benzene, dichloromethane, acetic acid, xylene and dimethylacetamide) with a 94% classification success rate.

    Full Text Available Electronic banking has been around for some time in the form of automatic teller machines and telephone transactions. More recently, it has been metamorphosed by the Internet; a new look and delivery channel for banking services that benefits both customers and banks. The objective of this paper is to find out the correlation between the anticipated benefits/challenges and encountered benefits/challenges. This paper therefore empirically, adopted the use of survey research to explore in quantitative terms the various challenges and benefits e-business poses to Nigeria businesses, with particular reference to Banking and Finance Industry. It was found out that there is statistically significant difference between the anticipated and encountered benefits and major challenge is the security breach faced the customers. We therefore recommend that workshops should be organized for customers periodically on how to keep their data secret especially on how to combine numbers to form password and Constant training of employees both local and international on new development in online trading should be encouraged.

    Electronic cigarette awareness and use has been increasing rapidly. E-cigarette brands have utilized social networking sites to promote their products, as the growth of the e-cigarette industry has paralleled that of Web 2.0. These online platforms are cost-effective and have unique technological features and user demographics that can be attractive for selective marketing. The popularity of multiple sites also poses a risk of exposure to social networks where e-cigarette brands might not have a presence. To examine the marketing strategies of leading e-cigarette brands on multiple social networking sites, and to identify how affordances of the digital media are used to their advantage. Secondary analyses include determining if any brands are benefitting from site demographics, and exploring cross-site diffusion of marketing content through multi-site users. We collected data from two e-cigarette brands from four social networking sites over approximately 2.5 years. Content analysis is used to search for themes, population targeting, marketing strategies, and cross-site spread of messages. Twitter appeared to be the most frequently used social networking site for interacting directly with product users. Facebook supported informational broadcasts, such as announcements regarding political legislation. E-cigarette brands also differed in their approaches to their users, from informal conversations to direct product marketing. E-cigarette makers use different strategies to market their product and engage their users. There was no evidence of direct targeting of vulnerable populations, but the affordances of the different sites are exploited to best broadcast context-specific messages. We developed a viable method to study cross-site diffusion, although additional refinement is needed to account for how different types of digital media are used.

    Electronic word of mouth (eWOM) has been an important factor influencing consumer purchase decisions. Using the ABC model of attitude, this study proposes a model to explain how eWOM affects online discussion forums. Specifically, we propose that platform (Web site reputation and source credibility) and customer (obtaining buying-related information and social orientation through information) factors influence purchase intentions via perceived positive eWOM review credibility, as well as product and Web site attitudes in an online community context. A total of 353 online discussion forum users in an online community (Fashion Guide) in Taiwan were recruited, and structural equation modeling (SEM) was used to test the research hypotheses. The results indicate that Web site reputation, source credibility, obtaining buying-related information, and social orientation through information positively influence perceived positive eWOM review credibility. In turn, perceived positive eWOM review credibility directly influences purchase intentions and also indirectly influences purchase intentions via product and Web site attitudes. Finally, we discuss the theoretical and managerial implications of the findings.

    Recent studies have separately examined the content and demographic reach of the advertising of electronic nicotine delivery systems (ENDS). No study to our knowledge has linked the two in investigating whether racial/ethnic groups are differentially exposed to the comparative messages conveyed in online ENDS advertisements. 932 unique ENDS advertisements (6311 total), which were posted on 3435 websites between December, 2009 and October, 2015, were categorized as either comparative or non-comparative with respect to the traditional cigarette. The race/ethnicity of website visitors was obtained from a proprietary source and used in constructing variables for racial/ethnic viewership. The variables for advertising content and website racial/ethnic viewership were then linked yielding a final sample of 551 unique ENDS advertisements (2498 total) on 1206 websites. A two-level hierarchical generalized linear model, used in estimating website racial/ethnic viewership as a predictor of comparative advertising, accounted for the nesting of advertisements (level 1) within 152 ENDS brands (level 2). In contrast to racial/ethnic minorities, a greater proportion of non-Hispanic whites visited websites with ENDS advertisements than the overall proportion of nonHispanic white U.S. Internet users. Yet, it was the advertisements on websites that appealed to Hispanics that had greater odds of comparing ENDS to traditional cigarettes. The lower exposure to ENDS advertising among racial/ethnic minorities versus non-Hispanic whites is consistent with survey data. Yet, the greater odds of comparative advertising of ENDS on websites that appeal to racial/ethnic minorities (ie, Hispanics) could impact the longterm health of minority smokers. This study's findings have important implications for the uptake of ENDS among minority smokers. If the comparative advertising yields greater interest and eventual use of ENDS, then minority smokers could either benefit from smoking cessation

    Full Text Available We analyze the role of intermediaries in electronic markets using detailed data of more than 14,000 originated loans on an electronic P2P (peer-to-peer lending platform. In such an electronic credit market, lenders bid to supply a private loan. Screening of potential borrowers and the monitoring of loan repayment can be delegated to designated group leaders. We find that these market participants act as financial intermediaries and significantly improve borrowers' credit conditions by reducing information asymmetries, predominantly for borrowers with less attractive risk characteristics. Our findings may be surprising given the replacement of a bank by an electronic marketplace.

    Fieldwork comes in many forms: individual research projects in unique places, large groups of students on organized fieldtrips, and everything in between those extremes. Supervising students in often distant places can be a logistical challenge and requires a significant time investment of their supervisors. We developed an online application for remote supervision of students on fieldwork. In our fieldworkonline webapp, which is accessible through a web browser, students can upload their field data in the form of a spreadsheet with coordinates (in a system of choice) and data-fields. Field data can be any combination of quantitative or qualitative data, and can contain references to photos or other documents uploaded to the app. The student's data is converted to a map with data-points that contain all the data-fields and links to photos and documents associated with that location. Supervisors can review the data of their students and provide feedback on observations, or geo-referenced feedback on the map. Similarly, students can ask geo-referenced questions to their supervisors. Furthermore, supervisors can choose different basemaps or upload their own. Fieldwork online is a useful tool for supervising students at a distant location in the field and is most suitable for first-order feedback on students' observations, can be used to guide students to interesting locations, and allows for short discussions on phenomena observed in the field. We seek user that like to use this system, we are able to provide support and add new features if needed. The website is built and controlled using Flask, an open-source Python Framework. The maps are generated and controlled using MapServer and OpenLayers, and the database is built in PostgreSQL with PostGIS support. Fieldworkonline and all tools used to create it are open-source.

    High-resolution electron microscopy is an efficient tool for characterizing heterogeneous nanostructures; however, currently the analysis is a laborious and time-consuming manual process. In order to be able to accurately and robustly quantify heterostructures, one must obtain a statistically high number of micrographs showing images of the appropriate sub-structures. The second step of analysis is usually the application of digital image processing techniques in order to extract meaningful structural descriptors from the acquired images. In this paper it will be shown that by applying on-line image processing and basic machine vision algorithms, it is possible to fully automate the image acquisition step; therefore, the number of acquired images in a given time can be increased drastically without the need for additional human labor. The proposed automation technique works by computing fields of structural descriptors in situ and thus outputs sets of the desired structural descriptors in real-time. The merits of the method are demonstrated by using combustion-generated black carbon samples. - Highlights: ► The HRTEM analysis of heterogeneous nanostructures is a tedious manual process. ► Automatic HRTEM image acquisition and analysis can improve data quantity and quality. ► We propose a method based on on-line image analysis for the automation of HRTEM image acquisition. ► The proposed method is demonstrated using HRTEM images of soot particles.

    The weighted electron energy loss factors (dimensionless) are defined by weighting the electron energy loss rate coefficients (per ion) with respect to the total radiative recombination rates. Both the unparameterized and parameterized weighted electron energy-loss factors for H-like to Ne-like ions from H (z=1) up to and including Zn (z=30), in a wide temperature range, are available here. For the unparameterized data set, the temperatures are set to the conventional ADAS temperature grid, i.e. c2*(10,20,50,100,200,...,2*106,5*106,107)K, where c is the ionic charge of the recombined ion. For the fitting parameters, the temperature should be in units of eV. We refer to the recombined ion when we speak of the radiative recombination of a certain ion, for example, for a bare oxygen ion capturing a free electron via radiative recombination to form H-like oxygen (O VIII, s=1, z=8). The fitting accuracies are better than 4%. (2 data files).

    Web-based training is frequently used by organizations as a convenient and low-cost way to teach employees new knowledge and skills. As web-based training is typically unproctored, employees may be held accountable to the organization by computer software that monitors their behaviors. The current study examines how the introduction of electronic performance monitoring may provoke negative emotional reactions and decrease learning among certain types of e-learners. Through motivated action theory and trait activation theory, we examine the role of performance goal orientation when e-learners are exposed to asynchronous and synchronous monitoring. We show that some e-learners are more susceptible than others to evaluation apprehension when they perceive their activities are being monitored electronically. Specifically, e-learners higher in avoid performance goal orientation exhibited increased evaluation apprehension if they believed asynchronous monitoring was present, and they showed decreased skill attainment as a result. E-learners higher on prove performance goal orientation showed greater evaluation apprehension if they believed real-time monitoring was occurring, resulting in decreased skill attainment.

  4. InsuOnline, an Electronic Game for Medical Education on Insulin Therapy: A Randomized Controlled Trial With Primary Care Physicians

    Science.gov (United States)

    2017-01-01

    Background Most patients with diabetes mellitus (DM) are followed by primary care physicians, who often lack knowledge or confidence to prescribe insulin properly. This contributes to clinical inertia and poor glycemic control. Effectiveness of traditional continuing medical education (CME) to solve that is limited, so new approaches are required. Electronic games are a good option, as they can be very effective and easily disseminated. Objective The objective of our study was to assess applicability, user acceptance, and educational effectiveness of InsuOnline, an electronic serious game for medical education on insulin therapy for DM, compared with a traditional CME activity.

    Most patients with diabetes mellitus (DM) are followed by primary care physicians, who often lack knowledge or confidence to prescribe insulin properly. This contributes to clinical inertia and poor glycemic control. Effectiveness of traditional continuing medical education (CME) to solve that is limited, so new approaches are required. Electronic games are a good option, as they can be very effective and easily disseminated. The objective of our study was to assess applicability, user acceptance, and educational effectiveness of InsuOnline, an electronic serious game for medical education on insulin therapy for DM, compared with a traditional CME activity. Primary care physicians (PCPs) from South of Brazil were invited by phone or email to participate in an unblinded randomized controlled trial and randomly allocated to play the game InsuOnline, installed as an app in their own computers, at the time of their choice, with minimal or no external guidance, or to participate in a traditional CME session, composed by onsite lectures and cases discussion.

    To enhance the early detection of emerging infectious diseases and bioterrorism events using companion animal-based surveillance. Washington, DC, small animal veterinary facilities (n=17) were surveyed to determine interest in conducting infectious disease surveillance. Using these results, an electronic-based online reporting system was developed and launched in August 2015 to monitor rates of canine influenza, canine leptospirosis, antibiotic resistant infections, canine parvovirus, and syndromic disease trends. Nine of the 10 facilities that responded expressed interest conducting surveillance. In September 2015, 17 canine parvovirus cases were reported. In response, a campaign encouraging regular veterinary preventative care was launched and featured on local media platforms. Additionally, during the system's first year of operation it detected 5 canine leptospirosis cases and 2 antibiotic resistant infections. No canine influenza cases were reported and syndromic surveillance compliance varied, peaking during National Special Security Events. Small animal veterinarians and the general public are interested in companion animal disease surveillance. The system described can serve as a model for establishing similar systems to monitor disease trends of public health importance in pet populations and enhance biosurveillance capabilities.

  7. ClinicalCodes: an online clinical codes repository to improve the validity and reproducibility of research using electronic medical records.

    Directory of Open Access Journals (Sweden)

    David A Springate

    Full Text Available Lists of clinical codes are the foundation for research undertaken using electronic medical records (EMRs. If clinical code lists are not available, reviewers are unable to determine the validity of research, full study replication is impossible, researchers are unable to make effective comparisons between studies, and the construction of new code lists is subject to much duplication of effort. Despite this, the publication of clinical codes is rarely if ever a requirement for obtaining grants, validating protocols, or publishing research. In a representative sample of 450 EMR primary research articles indexed on PubMed, we found that only 19 (5.1% were accompanied by a full set of published clinical codes and 32 (8.6% stated that code lists were available on request. To help address these problems, we have built an online repository where researchers using EMRs can upload and download lists of clinical codes. The repository will enable clinical researchers to better validate EMR studies, build on previous code lists and compare disease definitions across studies. It will also assist health informaticians in replicating database studies, tracking changes in disease definitions or clinical coding practice through time and sharing clinical code information across platforms and data sources as research objects.

    2015-09-29

    The rise in popularity of electronic cigarettes (e-cigarettes) and hookah over recent years has been accompanied by some confusion and uncertainty regarding the development of an appropriate regulatory response towards these emerging products. Mining online discussion content can lead to insights into people's experiences, which can in turn further our knowledge of how to address potential health implications. In this work, we take a novel approach to understanding the use and appeal of these emerging products by applying text mining techniques to compare consumer experiences across discussion forums. This study examined content from the websites Vapor Talk, Hookah Forum, and Reddit to understand people's experiences with different tobacco products. Our investigation involves three parts. First, we identified contextual factors that inform our understanding of tobacco use behaviors, such as setting, time, social relationships, and sensory experience, and compared the forums to identify the ones where content on these factors is most common. Second, we compared how the tobacco use experience differs with combustible cigarettes and e-cigarettes. Third, we investigated differences between e-cigarette and hookah use. In the first part of our study, we employed a lexicon-based extraction approach to estimate prevalence of contextual factors, and then we generated a heat map based on these estimates to compare the forums. In the second and third parts of the study, we employed a text mining technique called topic modeling to identify important topics and then developed a visualization, Topic Bars, to compare topic coverage across forums. In the first part of the study, we identified two forums, Vapor Talk Health & Safety and the Stopsmoking subreddit, where discussion concerning contextual factors was particularly common. The second part showed that the discussion in Vapor Talk Health & Safety focused on symptoms and comparisons of combustible cigarettes and e

    Protein oxidation is linked to cellular stress, aging, and disease. Protein oxidations that result in reactive species are of particular interest, since these reactive oxidation products may react with other proteins or biomolecules in an unmediated and irreversible fashion, providing a potential marker for a variety of disease mechanisms. We have developed a novel system to identify and quantitate, relative to other states, the sites of oxidation on a given protein. A specially designed Oxidation-dependent carbonyl-specific Element-Coded Affinity Mass Tag (O-ECAT), AOD, ((S)-2-(4-(2-aminooxy)-acetamido)-benzyl)-1, 4, 7, 10-tetraazacyclododecane-N, N', N'', N'''-tetraacetic acid, is used to covalently tag the residues of a protein oxidized to aldehyde or keto end products. After proteolysis, the resulting AOD-tagged peptides are affinity purified, and analyzed by nanoLC-FTICR-MS, which provides high specificity in extracting co-eluting AOD mass pairs with a unique mass difference and affords relative quantitation based on isotopic ratios. Using this methodology, we have mapped the surface oxidation sites on a model protein, recombinant human serum albumin (rHSA) in its native form (as purchased) and after FeEDTA oxidation. A variety of modified amino acid residues including lysine, arginine, proline, histidine, threonine, aspartic and glutamic acids, were found to be oxidized to aldehyde and keto end products. The sensitivity of this methodology is shown by the number of peptides identified, twenty peptides on the native protein and twenty-nine after surface oxidation using FeEDTA and ascorbate. All identified peptides map to the surface of the HSA crystal structure validating this method for identifying oxidized amino acids on protein surfaces. In relative quantitation experiments between FeEDTA oxidation and native protein oxidation, identified sites showed different relative propensities towards oxidation independent of amino acid

    AtChem On-line1 is a simple to use zero-dimensional box modelling toolkit, developed for use by laboratory, field and chamber scientists. Any set of chemical reactions can be simulated, in particular the whole Master Chemical Mechanism (MCM2) or any subset of it. Parameters and initial data can be provided through a self-explanatory web form and the resulting model is compiled and run on a dedicated server. The core part of the toolkit, providing a robust solver for thousands of chemical reactions, is written in Fortran and uses SUNDIALS3 CVODE libraries. Chemical systems can be constrained at multiple, user-determined timescales; this enabled studies of radical chemistry at one minute timescales. AtChem On-line is free to use and requires no installation - a web browser, text editor and any compressing software is all the user needs. CPU and storage are provided by the server (input and output data are saved indefinitely). An off-line version is also being developed, which will provide batch processing, an advanced graphical user interface and post-processing tools, for example, Rate of Production Analysis (ROPA) and chainlength analysis. The source code is freely available for advanced users wishing to adapt and run the program locally. Data management, dissemination and archiving are essential in all areas of science. In order to do this in an efficient and transparent way, there is a critical need to capture high quality metadata/provenance for modelling activities. An Electronic Laboratory Notebook (ELN) has been developed in parallel with AtChem Online as part of the EC EUROCHAMP24 project. In order to use controlled chamber experiments to evaluate the MCM, we need to be able to archive, track and search information on all associated chamber model runs, so that they can be used in subsequent mechanism development. Therefore it would be extremely useful if experiment and model metadata/provenance could be easily and automatically stored electronically

    An approach to an inhibition bioelectronic tongue is presented. The work is focused on development of an automated flow system to carry out experimental assays, a custom potentiostat to measure the response from an enzymatic biosensor, and an inhibition protocol which allows on-line detections. A Multi-commuted Flow Analysis system (MCFA) was selected and developed to carry out assays with an improved inhibition method to detect the insecticides chlorpyrifos oxon (CPO), chlorfenvinfos (CFV) and azinphos methyl-oxon (AZMO). The system manifold comprised a peristaltic pump, a set of seven electronic valves controlled by a personal computer electronic interface and software based on LabView® to control the sample dilutions into the cell. The inhibition method consists in the injection of the insecticide when the enzyme activity has reached the plateau of the current; with this method the incubation time is avoided. A potentiostat was developed to measure the response from the enzymatic biosensor. Low limits of detection of 10 nM for CPO, CFV, and AZMO were achieved.

    Full Text Available INTRODUCTION: Open access publishing is becoming increasingly popular within the biomedical sciences. SciELO, the Scientific Electronic Library Online, is a digital library covering a selected collection of Brazilian scientific journals many of which provide open access to full-text articles.This library includes a number of dental journals some of which may include reports of clinical trials in English, Portuguese and/or Spanish. Thus, SciELO could play an important role as a source of evidence for dental healthcare interventions especially if it yields a sizeable number of high quality reports. OBJECTIVE: The aim of this study was to identify reports of clinical trials by handsearching of dental journals that are accessible through SciELO, and to assess the overall quality of these reports. MATERIAL AND METHODS: Electronic versions of six Brazilian dental Journals indexed in SciELO were handsearched at www.scielo.br in September 2008. Reports of clinical trials were identified and classified as controlled clinical trials (CCTs - prospective, experimental studies comparing 2 or more healthcare interventions in human beings or randomized controlled trials (RCTs - a random allocation method is clearly reported, according to Cochrane eligibility criteria.

    Open access publishing is becoming increasingly popular within the biomedical sciences. SciELO, the Scientific Electronic Library Online, is a digital library covering a selected collection of Brazilian scientific journals many of which provide open access to full-text articles.This library includes a number of dental journals some of which may include reports of clinical trials in English, Portuguese and/or Spanish. Thus, SciELO could play an important role as a source of evidence for dental healthcare interventions especially if it yields a sizeable number of high quality reports. The aim of this study was to identify reports of clinical trials by handsearching of dental journals that are accessible through SciELO, and to assess the overall quality of these reports. Electronic versions of six Brazilian dental Journals indexed in SciELO were handsearched at www.scielo.br in September 2008. Reports of clinical trials were identified and classified as controlled clinical trials (CCTs - prospective, experimental studies comparing 2 or more healthcare interventions in human beings) or randomized controlled trials (RCTs - a random allocation method is clearly reported), according to Cochrane eligibility criteria. CRITERIA TO ASSESS METHODOLOGICAL QUALITY INCLUDED: method of randomization, concealment of treatment allocation, blinded outcome assessment, handling of withdrawals and losses and whether an intention-to-treat analysis had been carried out. The search retrieved 33 CCTs and 43 RCTs. A majority of the reports provided no description of either the method of randomization (75.3%) or concealment of the allocation sequence (84.2%). Participants and outcome assessors were reported as blinded in only 31.2% of the reports.

    This chapter explores what makes online advertising different from traditional advertising channels. We argue that online advertising differs from traditional advertising channels in two important ways: measurability and targetability. Measurability is higher because the digital nature of online advertising means that responses to ads can be tracked relatively easily. Targetability is higher because data can be automatically tracked at an individual level, and it is relatively easy to show di...

    Full Text Available The advantages of electronic retailing can, among other things, result in uncontrolled buying by online consumers, i.e. in extreme buying behavior. The main purpose of this paper is to analyze and determine the buying patterns of Generation Y online consumers in order to explore the existence of different types of behavior based on the characteristics of online buying. The paper also aims at exploring the relationship between extracted factors and Generation Y consumers’ buying intentions. Empirical research was conducted on a sample of 515 consumers in the Dubrovnik-Neretva County. Based on the factor analysis, research results indicate that Generation Y online consumers are influenced by three factors: compulsivity, impulsivity, and functionality. The analysis of variance reveals that significant differences exist between the extracted factors and Generation Y’s online buying characteristics. In addition, correlation analysis shows a statistically significant correlation between the extracted factors and Generation Y’s buying intentions.

    2005-11-15

    Single-photon ionization (SPI) using vacuum ultraviolet (VUV) light produced by an electron beam pumped rare gas excimer source has been coupled to a compact and mobile time-of-flight mass spectrometer (TOFMS). The novel device enables real-time on-line monitoring of organic trace substances in complex gaseous matrixes down to the ppb range. The pulsed VUV radiation of the light source is employed for SPI in the ion source of the TOFMS. Ion extraction is also carried out in a pulsed mode with a short time delay with respect to ionization. The experimental setup of the interface VUV light source/time-of-flight mass spectrometer is described, and the novel SPI-TOFMS system is characterized by means of standard calibration gases. Limits of detection down to 50 ppb for aliphatic and aromatic hydrocarbons were achieved. First on-line applications comprised real-time measurements of aromatic and aliphatic trace compounds in mainstream cigarette smoke, which represents a highly dynamic fluctuating gaseous matrix. Time resolution was sufficient to monitor the smoking process on a puff-by-puff resolved basis. Furthermore, human breath analysis has been carried out to detect differences in the breath of a smoker and a nonsmoker, respectively. Several well-known biomarkers for smoke could be identified in the smoker's breath. The possibility for even shorter measurement times while maintaining the achieved sensitivity makes this new device a promising tool for on-line analysis of organic trace compounds in process gases or biological systems.

    2015-06-15

    Purpose: To investigate the clinical utility of on-line verification of respiratory gated VMAT dosimetry during treatment. Methods: Portal dose images were acquired during treatment in integrated mode on a Varian TrueBeam (v. 1.6) linear accelerator for gated lung and liver patients that used flattening filtered beams. The source to imager distance (SID) was set to 160 cm to ensure imager clearance in case the isocenter was off midline. Note that acquisition of integrated images resulted in no extra dose to the patient. Fraction 1 was taken as baseline and all portal dose images were compared to that of the baseline, where the gamma comparison and dose difference were used to measure day-to-day exit dose variation. All images were analyzed in the Portal Dosimetry module of Aria (v. 10). The portal imager on the TrueBeam was calibrated by following the instructions for dosimetry calibration in service mode, where we define 1 calibrated unit (CU) equal to 1 Gy for 10×10 cm field size at 100 cm SID. This reference condition was measured frequently to verify imager calibration. Results: The gamma value (3%, 3 mm, 5% threshold) ranged between 92% and 100% for the lung and liver cases studied. The exit dose can vary by as much as 10% of the maximum dose for an individual fraction. The integrated images combined with the information given by the corresponding on-line soft tissue matched cone-beam computed tomography (CBCT) images were useful in explaining dose variation. For gated lung treatment, dose variation was mainly due to the diaphragm position. For gated liver treatment, the dose variation was due to both diaphragm position and weight loss. Conclusion: Integrated images can be useful in verifying dose delivery consistency during respiratory gated VMAT, although the CBCT information is needed to explain dose differences due to anatomical changes.

    Geoscience faculty at the University of South Florida (USF), Florida Gulf Coast University (FCGU), Valencia College (VC) and Florida International University (FIU) have teamed to construct, test and disseminate geoscience curricula in which microbeam analytical instruments are operated by undergraduates, with data gathered in the classroom in real-time over the internet. Activities have been developed for courses Physical Geology, Oceanography, Earth Materials, Mineralogy/Petrology and Stratigraphy using the Scanning Electron Microscope (SEM) and Electron Probe Microanalyzer (EPMA) housed in the Florida Center for Analytical Electron Microscopy (FCAEM; https://fcaem.fiu.edu) at FIU. Students and faculty send research materials such as polished rock sections and microfossil mounts to FCAEM to be examined during their scheduled class and lab periods. Student control of both decision-making and selection of analytical targets is encouraged. The objective of these activities is to move students from passive learning to active, self-directed inquiry at an early stage in their undergraduate career, while providing access to advanced instruments that are not available at USF, FGCU and VC. These strategies strongly facilitate student interest in undergraduate research making use of these instruments and one positive outcome to date is an increased number of students undertaking independent research projects. Prior research by USF PI Jeff Ryan indicated that various barriers related to instrument access and use hindered interested geoscience faculty in making use of these tools and strategies. In the current project, post-doctoral researcher Dr. Sven Holbik acts as a facilitator, working directly with faculty from other institutions one-on-one to provide initial training and support, including on-site visits to field check classroom technology when needed. Several new educators and institutions will initiate classroom activities using FCAEM instrumentation this Fall.

    Healthcare has entered the electronic domain. This domain has improved data collection and storage abilities while allowing almost instantaneous access and results to data queries. Furthermore, it allows direct communication between healthcare providers and health consumers. The development of privacy, confidentiality, and security principles are necessary to protect consumers' interests against inappropriate access. Studies have shown that the health consumer is the important stakeholder in this process. With the international push toward electronic health records (EHRs), this article presents the importance of secure EHR systems from the public's perspective. To examine the public's perception of the security of electronic systems and report on how their perceptions can shape the building of stronger systems. A cross-sectional survey (September-November 2005) of people attending healthcare providers (n = 400) was conducted in the 4 major cities in New Zealand. Participants were surveyed on computer use, knowledge of EHR-proposed benefits and issues, security issues, and demographics. A total of 300 surveys were completed and returned (a 75% response rate), with 180 (60%) being women. One hundred eighty-eight (62.6%) had not heard of EHRs, with those who had heard of them indicating that they were a positive innovation in the health sector. However, 202 (73.3%) participants were highly concerned about the security and privacy of their health records. This feeling was further accentuated when participants were asked about security of electronic systems. Participants were worried about hackers (79.4%), vendor access (72.7%), and malicious software (68%). Participants were also introduced to various security systems, and in each case, over 80% of participants believed that these would make EHR systems more secure. A number of chi-square tests were carried out with each variable, and it was found that there were strong relationships between age, location, computer use

    Payne, Meredith Lindsay

    1995-01-01

    The main objective was to assist in the production of electronic images in the Electronic Photography Lab (EPL). The EPL is a new facility serving the electronic photographic needs of the Langley community. The purpose of the Electronic Photography lab is to provide Langley with access to digital imaging technology. Although the EPL has been in operation for less than one year, almost 1,000 images have been produced. The decision to establish the lab was made after careful determination of the centers needs for electronic photography. The LaRC community requires electronic photography for the production of electronic printing, Web sites, desktop publications, and its increased enhancement capabilities. In addition to general use, other considerations went into the planning of the EPL. For example, electronic photography is much less of a burden on the environment compared to conventional photography. Also, the possibilities of an on-line database and retrieval system could make locating past work more efficient. Finally, information in an electronic image is quantified, making measurements and calculations easier for the researcher.

  13. Physical characteristics of the ECAT EXACT3D positron tomograph

    2000-09-01

    The 'EXACT3D' positron tomograph, which is now in routine clinical research use, was developed with the aim of achieving unprecedented sensitivity, high spatial and temporal resolution and simplicity of design using proven detector technology. It consists of six rings of standard detector blocks (CTI/Siemens EXACT HR+) with 4.39 mm x 4.05 mm x 30 mm elements, giving an axial field of view (FOV) of 23.4 cm. This extended FOV and the absence of interplane septa and retractable transmission rod sources has allowed greatly simplified gantry and detector cassette design. Operation in exclusive 3D mode requires an alternative to the conventional coincidence method for transmission scanning, and a single photon approach using a hydraulically driven {sup 137}Cs point source has been implemented. The tomograph has no other moving parts. A single time frame of data without any compression is very large (>300 Mbyte) and two approaches are employed to overcome this difficulty: (a) adjacent sinograms can be summed automatically into different combinations and (b) listmode (event-by-event) acquisition has been instituted, which is both storage efficient (particularly for acquisition of sparse data sets) and maximizes temporal resolution. The high-speed I/O and computing hardware can maintain a sustained acquisition rate of about 4 million coincidence events per second. A disadvantage of the large axial FOV in 3D is the increased sensitivity to activity outside the coincidence FOV. However, this can be minimized by additional side shielding. The mean spatial resolution is 4.8{+-}0.2 mm FWHM (transaxial, 1 cm off-axis) and 5.6{+-}0.5 mm (axial, on-axis). Its absolute efficiency is 5.8% for a line source in air (just spanning the axial FOV) and 10% for a central point source (with thresholds of 350-650 keV). For a uniform 20 cm diameter cylinder, the efficiency is 69 kcps kBq{sup -1} ml{sup -1} (after subtraction of a scatter fraction of 42%). Sensitivity relative to the EXACT HR+ (with four rings of blocks) is 2.5 (3D) and 12 (2D) times respectively. The rate of random events in blood flow studies in the brain and body, using {sup 15}O-labelled water, can be controlled by limiting the administered dose and inserting additional side shielding.

    2008-08-15

    Nuclear track detectors (NTDs) have seen a major expansion in application to general physical and geological problems reflecting its advances in understanding the exhalation dependence of radon as well as radon and radium concentration distributions in the earth's crust. However, considerable uncertainties still persist, in particular, concerning the detection efficiency of track detectors which are not calibrated precisely to a standard method or an active detector of a unique efficiency. In this investigation, CR-39 NTDs and an electronic radon gas analyzer 'Alpha GUARD' were used for the measurement of radon exhalation rate and radium concentration in phosphate samples collected from two different mines of El-Sobaeya and El-Suez, Egypt. The phosphate sample was loaded into an emanation container (Genitron Instruments GmbH) equipped with a PC-based radon gas analyzer. The CR-39 track detectors were mounted inside a diffusion cup used simultaneously with the Alpha GUARD radon gas analyzer. Radium activity in phosphate samples was found to vary from 1.8 to 361.3kBqkg{sup -1}. The radon exhalation rates in these samples were found to vary from 0.020 (0.003) to 4.125Bqm{sup -2}h{sup -1}(0.658Bqkg{sup -1}h{sup -1})

  16. On-line DLTS investigations of the mono- and di-vacancy in p-type silicon after low temperature electron irradiation

    Zangenberg, Nikolaj E-mail: nrz@ifa.au.dk; Goubet, Jean-Jacques; Nylandsted Larsen, Arne

    2002-01-01

    Using deep level transient spectroscopy (DLTS) and Laplace-DLTS, we have investigated vacancy-related defects created in boron-doped epitaxial Si by 2 MeV electron irradiations at low temperatures ({<=}40 K). The vacancy level is found at E{sub v}+0.12 eV together with a DLTS peak at E{sub v}+0.20 eV which anneals at {approx}140 K and is tentatively identified as a vacancy in a different configuration. The emission rate of the dominant vacancy-related deep level in the temperature range from 200 to 550 K, namely the (0/+) transition of the di-vacancy (V{sub 2}), displays a very large dependence of the emission rate on the electric field strength in the depletion region of the diodes. This dependence is unexpected in terms of the classical Poole-Frenkel effect, given the neutral charge state of V{sub 2} before hole capture. The effect of high fields appears to be caused by phonon assisted tunneling. When V anneals around 200 K, a new complex assigned to a vacancy-boron pair gives rise to two charge states. Quenching experiments with reverse bias show that the complex is bistable. It anneals at 260 K.

  6. Compact ultrafast orthogonal acceleration time-of-flight mass spectrometer for on-line gas analysis by electron impact ionization and soft single photon ionization using an electron beam pumped rare gas excimer lamp as VUV-light source.

    Mühlberger, F; Saraji-Bozorgzad, M; Gonin, M; Fuhrer, K; Zimmermann, R

    2007-11-01

    Orthogonal acceleration time-of-flight mass spectrometers (oaTOFMS), which are exhibiting a pulsed orthogonal extraction of ion bunches into the TOF mass analyzer from a continuous primary ion beam, are well-suited for continuous ionization methods such as electron impact ionization (EI). Recently an electron beam pumped rare gas excimer lamp (EBEL) was introduced, which emits intensive vacuum UV (VUV) radiation at, e.g., 126 nm (argon excimer) and is well suited as the light source for soft single photon ionization (SPI) of organic molecules. In this paper, a new compact oaTOFMS system which allows switching between SPI, using VUV-light from an EBEL-light source, and conventional EI is described. With the oaTOFMS system, EBEL-SPI and EI mass spectral transients can be recorded at very high repetition rates (up to 100 kHz), enabling high duty cycles and therefore good detection efficiencies. By using a transient recorder card with the capability to perform on-board accumulation of the oaTOF transients, final mass spectra with a dynamic range of 106 can be saved to the hard disk at a rate of 10 Hz. As it is possible to change the ionization modes (EI and SPI) rapidly, a comprehensive monitoring of complex gases with highly dynamic compositions, such as cigarette smoke, is possible. In this context, the EI based mass spectra address the bulk composition (compounds such as water, oxygen, carbon dioxide, etc. in the up to percentage concentration range) as well as some inorganic trace gases such as argon, sulfur dioxide, etc. down to the low ppm level. The EBEL-SPI mass spectra on the other hand are revealing the organic composition down to the lower ppb concentration range.

    2004-02-01

    A survey of 11 positive features and 10 discouraging features of online shopping was carried out on 180 students and identified certain behavioral patterns for online shoppers versus non-shoppers. It was found that online shoppers have consistently stronger positive feelings about online shopping than do non-shoppers. On the other hand, non-shoppers have more negative feelings about online shopping than do shoppers, but not consistently so. Online shoppers are aware of some of the discouraging features of online shopping, but these features do not deter them from shopping online. The implication for marketers is that they should focus on making the experience of online shopping more accommodating and more user-friendly since the positive features of online shopping ("convenience" and "efficiency") appear to be more important than the negative features ("effort/impersonality").

    Full Text Available Online archives are of increasing importance in Archaeological Informatics, but like any new genre they prompt a number of questions. What is their relationship to publication? What should go in them? How should they be delivered and indexed? Can they be preserved? Whilst their delivery requires technology, we must also consider how that technology should best be employed in the service of our discipline. This article attempts to address some of these questions but it need not be read from start to finish. The links from this summary provide one fairly linear route through the text but each section is self-contained and can also be accessed directly from the Contents page. The problems posed by effective publication of archaeological fieldwork have exercised the profession for many decades. The issues raised go to the core of discussion of whether preservation by record is a valid concept, and indeed whether archaeological data exist. There are different schools of thought about the relationship between publication and archiving, but hopefully we can accept that data are recorded observations but still agree that they have a re-use value for re-examination and re-interpretation. Since the 1960s archaeology has experienced a publication crisis point. The scenario is familiar. Excavation is destruction; it is an unrepeatable experiment and the archaeologist has a professional obligation to make a full and accessible record of his/her observations. Yet full publication is increasingly expensive and difficult, and excavation monographs are read by few people, and bought by even fewer. In England the development of post-PPG16 fieldwork has exacerbated the problem by creating a mountain of unpublished grey literature and making the work of synthesis even harder; a similar situation exists in other countries. Meanwhile museum archives are also reaching breaking point; most are running out of storage space, few can provide facilities for access, and

    Nanoencapsulation of antioxidant molecules on protein nanoparticles (NPs) could be an advanced approach for providing stable, better food nutraceuticals and anticancer drugs. The bioavailability and stability of catechin (CAT) and epicatechin (ECAT) were very poor. In the present study, the CAT and ECAT were loaded on bovine serum albumin (BSA) NPs following desolvation method. The transmission electron microscope (TEM) and atomic force microscope (AFM) recorded size of CAT-BSA NPs and ECAT-BSA NPs were 45 ± 5 nm and 48 ± 5 nm respectively. The encapsulation efficiency of CAT and ECAT on BSA NPs was found to be 60.5 and 54.5 % respectively. CAT-BSA NPs and ECAT-BSA NPs show slow and sustained in vitro release. The CAT-BSA NPs and ECAT-BSA NPs were stable in solution at various temperatures 37 °C, 47 °C and 57 °C. DPPH assay revealed that CAT and ECAT maintained their functional activity even after encapsulation on BSA NPs. Furthermore, the efficacy of CAT-BSA NPs and ECAT-BSA NPs determined against A549 cell lines was found to be improved. CAT and ECAT aptly encapsulated in BSA NPs, showed satisfactory sustained release, maintained antioxidant potential and found improved efficacy. This has thus suggested their more effective use in food and nutraceuticals as well as in medical field.

We show that well known fair division procedures like cut-and-choose and the Dubins-Spanier moving knife procedure can be adapted to apply to such online problems. We propose some desirable properties that online cake cutting procedures might possess like online forms of proportionality and envy-freeness, and identify which properties are in fact possessed by the different online cake procedures.

    This is a comprehensive study of the many facets of an entirely online organic chemistry course. Online homework with structure-drawing capabilities was found to be more effective than written homework. Online lecture was found to be just as effective as in-person lecture, and students prefer an online lecture format with shorter Webcasts. Online office hours were found to be effective, and discussion sessions can be placed online as well. A model was created that explains 36.1% of student performance based on GPA, ACT Math score, grade in previous chemistry course, and attendance at various forms of discussion. Online exams have been created which test problem-solving skills and is instantly gradable. In these exams, students can submit answers until time runs out for different numbers of points. These facets were combined effectively to create an entirely online organic chemistry course which students prefer over the in-person alternative. Lastly, there is a vision for where online organic chemistry is going and what can be done to improve education for all.

    Full Text Available Internet and Communication Technologies are transforming education, taking it out of the traditional classroom and making it open, affordable and dynamic. Universities, publishers, corporates and individual lecturers are creating online courses. A course consists of video lectures, electronic study notes, online tests and assignments. Anyone who wishes to learn may enroll in these courses, take the lessons, complete the tests and assignments, and receive a certificate upon successful completion of the course. These Massive Open Online Courses (MOOCs are making world class higher education available to all those who wish to learn, regardless of age, location or educational background. Education faces a number of challenges worldwide. Over 366 million youth are unenrolled in colleges. College education is growing more expensive. Many institutions face shortage of qualified faculty members, funding and infrastructure. Education over the internet can address many of these issues. Online classes are scaleable – a class of 50 can be expanded to teach 50,000. Teaching and learning over the internet can be done at a fraction of the cost of traditional classroom teaching. Flexibility, mobility, use of multimedia technologies, constant syllabus revision, collaboration and interactive discussions give online education an advantage. This is still an evolving field. New partnerships, innovations and technological advances are revolutionizing teaching and learning, and clearly, online education is an integral part of the future of education.

    Full Text Available Ranking is one of the key measures for evaluating universities. Progress of research at universities is often measured by the rate of its publications. It is also common knowledge in the field of research that journal publications owe their success to their impact factor. However, one of the contributing factors that affect a journal's impact factor is the accessibility and availability of its content. The law of statistics suggests that publishing an electronic version of the journal content through online publications is likely to boost the visibility of a journal; hence, improving the impact factor. The ability to publish electronically is often received favorably by the research community. Despite advances in electronic journal publishing, only recently, online journals have made their way into Iranian university journal publishing. This paper evaluates and reports on the extent of online journal publications among Iranian universities. For the purposes of this study, 653 journals published by 183 universities were studied. The results reveal that 66.7% of all universities have online copies of their journals. This study is carried out for three categories of universities; the Ministry of Health and medical Education universities, the Ministry of Science, Research, and Technology universities (MSRT, and Islamic Azad University Branches (IAU.

    Full Text Available Objective – To investigate the relationship between academics’ use of library electronic resources and their opinions regarding how these resources have impacted their work, and to investigate the association between this perceived influence and publication productivity during the previous two years.Design – Two specific questions added to an annual online user-survey questionnaire; additional data mined from surveySetting – Twenty-two Finnish Universities served by FinELib, the Finnish Electronic Library.Subjects – Seven hundred and sixty seven academic staff and full-time doctoral students.Methods – A questionnaire was posted in April 2007 on FinELib’s homepage and advertised on each university library’s mainpage, and focused on respondents’ experience in the previous two years. Participants selected answers either from a list of category choices, or, when measuring perceptions, by rating agreement with statements along a four-point scale. Controlled variables measured were the respondents’ academic position, their discipline, membership in a research group, whether their literature use was discipline-specific or interdisciplinary, and their perception of the availability online of the relevant core literature. The independent variable measured was the scholars’ perception of the impact of the use of electronic library resources on their work. The dependent variable measured was the scholars’ self-reported publications in the two years preceding the survey.Main Results – Participants reported a positive impact on the efficiency of their work, most strongly in areas of ease of access, with lesser impacts in the range of materials available to them and the ease with which they can keep up-to-date in their field. To a lesser extent, the scholars perceived a positive impact on the quality of their work.

    Oceanography at UCSB is an introductory general education science course taken by up to 200 students per quarter. The emphasis is on learning science process by engaging in authentic science activities that use real earth data. Recently, to increase student motivation, the course has been modified to include an Earth Summit framework. The online support being developed for this course is the first step in the creation of a completely online oceanography class. Foundation software was first tested in the class during Spring 2001. Online activities that are supported are writing and instructor feedback, online threaded discussion with live chat and graphics, automatically graded homeworks and games, auto graded quizzes with questions randomly selected from a database, and thought problems graded by the instructor(s). Future plans include integration with commercial course management software. To allow choice of assignments, all course activities totaled110%. Since grades were based on A=90-100, B=80-90, C= 70-80, etc, it was possible to get a better than A grade. Students see the effect (on their grade) of each assignment by calculating their current course grade. Course activities included (most of which are automatically graded): weekly lab homeworks, weekly mini-quizzes (10 multiple choice questions selected at random from a topic database), weekly thought questions (graded by the TA), 3 written assignments, and "Question of the Day" from lecture (credit given for handing it in), The online writing software allowed students to enter their writing, edit and link to graphic images, print the paper, and electronically hand it in. This has the enormous advantage of allowing the instructor and TA's convenient access to all student papers. At the end of the course, students were asked how effective each of the course activities were in learning the course material.

    In this paper, we explore the possibilities and limitations of recovering sparse signals in an online fashion. Employing a mean field approximation to the Bayes recursion formula yields an online signal recovery algorithm that can be performed with a computational cost that is linearly proportional to the signal length per update. Analysis of the resulting algorithm indicates that the online algorithm asymptotically saturates the optimal performance limit achieved by the offline method in the presence of Gaussian measurement noise, while differences in the allowable computational costs may result in fundamental gaps of the achievable performance in the absence of noise.

    News media organizations like newspapers and broadcasters have long functioned as gatekeepers between news and audiences, but with the rise of digital media, the search engines and social networking sites that are central to how most people navigate online increasingly complement news media......) and where non-journalistic actors too serve as gates between news and audiences. In this paper, I adopt such a broader approach and outline three varieties of online gatekeeping that each integrate different technologies in the gatekeeping process, but do so in different ways and for different purposes...... media websites remain amongst the most important gateways to news online. But they are increasingly supplemented by other, second-order online gatekeepers like search engines and social networking sites that, while rarely producing original content defined as “news”, increasingly serve as alternative...

    Although problem gambling is becoming more prevalent, research shows that many problem gamblers do not seek help. Online social support forums have become an increasingly popular option for receiving support for problem gambling. Few researchers have explored how participants within these forums interact, or what is supportive about participation in online communities. Melding netnography (ethnographic approaches online), discourse analysis, and ethnomethodology, we analyzed the discursive interactions of self-identified problem gamblers on an online forum. We report on the characteristics of this unique setting, the common discourses that members used, and how they discursively accomplished various interactional tasks, including constructing identities, and negotiating membership, legitimacy, and support. We conclude with recommendations for practitioners and researchers interested in better understanding people trying to overcome problem gambling and other behavioral concerns.

    Full Text Available Internet has developed in new delivery channels electronic transactions are increasing rapidly. This need has arisen to understand how they perceive directly to buy consumers. Most of the people who use the internet to purchase goods online, but that there are still some reasons for which consumers are reluctant to buy online. The attitudes of people toward the purchase online are different in Pakistan. The purpose of this study is to review the factors felt reservation of consumers in online shopping. The main objective of this research is to study, especially what are factors affecting the consumers directly for online shopping. To this end, a survey was conducted and the 120 questionnaires were distributed among the students of different universities and the general public. The replies have been analyzed by means of frequency distribution, average and chart analysis. The results of the survey analysis has shown that most of the people already shopping online and prefer to make their purchases online, but there are some factors such as psychological factors, social factors emotional factors, and the privacy factors which affect the buyer attitudes of online purchases. The protection of privacy and security are major problems that affect the behavior of the population to buy online. Various attitudes of consumers toward online shopping are not in rest in the study which reveals that the purchase online is easy, comfortable and better that conventional shopping due to various factors. Price, the trust, the convenience and the recommendations have been identified as important factors. Price was considered to be the most fascinating and affecting factor for the majority of students and the general public. Most of the consumers hesitate not to do shopping online, because of the insecure payment and transactions systems.

    This study investigated whether several psychopathology variables, including suicidality, could predict the time people spend using the internet (hours online). Next, we examined a specific at-risk population (suicidal individuals) by their online behaviors, comparing suicidal individuals who went online for suicide-related purposes with suicidal individuals who did not go online for suicide-related purposes. An anonymous online sample of 713 (aged 18-71) reported hours online, psychiatric histories, and completed several standardized scales. After accounting for age and education, hierarchical regression modeling showed that the assessed psychopathology variables, including suicidality, did not explain significant variance in hours online. Hours online were better predicted by younger age, greater willingness to develop online relationships, higher perceived social support, higher curiosity, and lower extraversion. Suicidal participants, who did or did not go online for suicide-related purposes, did not differ on hours online. Multiple regression modeling showed that those who went online for suicide-related purposes were likely to be younger, more suicidal, and more willing to seek help from online mental health professionals. These findings revealed that hours online are not a valid indicator of psychopathology. However, studying online behaviors of specific at-risk groups could be informative and useful, including for suicide prevention efforts. Copyright © 2017. Published by Elsevier B.V.

    The PHENIX On-Line system takes signals from the Front End Modules (FEM) on each detector subsystem for the purpose of generating events for physics analysis. Processing of event data begins when the Data Collection Modules (DCM) receive data via fiber-optic links from the FEMs. The DCMs format and zero suppress the data and generate data packets. These packets go to the Event Builders (EvB) that assemble the events in final form. The Level-1 trigger (LVL1) generates a decision for each beam crossing and eliminates uninteresting events. The FEMs carry out all detector processing of the data so that it is delivered to the DCMs using a standard format. The FEMs also provide buffering for LVL1 trigger processing and DCM data collection. This is carried out using an architecture that is pipelined and deadtimeless. All of this is controlled by the Master Timing System (MTS) that distributes the RHIC clocks. A Level-2 trigger (LVL2) gives additional discrimination. A description of the components and operation of the PHENIX On-Line system is given and the solution to a number of electronic infrastructure problems are discussed.

    Online auction, shopping, electronic billing etc. all such types of application involves problems of fraudulent transactions. Online fraud occurrence and its detection is one of the challenging fields for web development and online phantom transaction. As no-secure specification of online frauds is in research database, so the techniques to evaluate and stop them are also in study. We are providing an approach with Hidden Markov Model (HMM) and mobile implicit authentication to find whether the user interacting online is a fraud or not. We propose a model based on these approaches to counter the occurred fraud and prevent the loss of the customer. Our technique is more parameterized than traditional approaches and so,chances of detecting legitimate user as a fraud will reduce.

    A portable and readily aligned online microspectrophotometer that can be easily installed on macromolecular crystallography beamlines is described. It allows measurement of the spectral characteristics of macromolecular crystals prior, during, and after the X-ray diffraction experiment. X-rays can produce a high concentration of radicals within cryo-cooled macromolecular crystals. Some radicals have large extinction coefficients in the visible (VIS) range of the electromagnetic spectrum, and can be observed optically and spectrally. An online microspectrophotometer with high temporal resolution has been constructed that is capable of measuring UV/VIS absorption spectra (200–1100 nm) during X-ray data collection. The typical X-ray-induced blue colour that is characteristic of a wide range of cryo-conditions has been identified as trapped solvated electrons. Disulphide-containing proteins are shown to form disulphide radicals at millimolar concentrations, with absorption maxima around 400 nm. The solvated electrons and the disulphide radicals seem to have a lifetime in the range of seconds up to minutes at 100 K. The temperature dependence of the kinetics of X-ray-induced radical formation is different for the solvated electrons compared with the disulphide radicals. The online microspectrophotometer provides a technique complementary to X-ray diffraction for analysing and characterizing intermediates and redox states of proteins and enzymes.

    We study the online clustering problem where data items arrive in an online fashion. The algorithm maintains a clustering of data items into similarity classes. Upon arrival of v, the relation between v and previously arrived items is revealed, so that for each u we are told whether v is similar to u. The algorithm can create a new cluster for v and merge existing clusters. When the objective is to minimize disagreements between the clustering and the input, we prove that a natural greedy algorithm is O(n)-competitive, and this is optimal. When the objective is to maximize agreements between the clustering and the input, we prove that the greedy algorithm is .5-competitive; that no online algorithm can be better than .834-competitive; we prove that it is possible to get better than 1/2, by exhibiting a randomized algorithm with competitive ratio .5+c for a small positive fixed constant c.

    Peer support groups have a long history and have been shown to improve health outcomes. With the increasing familiarity with online social networks like Facebook and ubiquitous access to the Internet, online social support networks are becoming popular. While studies have shown the benefit of these networks in providing emotional support or meeting informational needs, robust data on improving outcomes such as a decrease in health services utilization or reduction in adverse outcomes is lacking. These networks also pose unique challenges in the areas of patient privacy, funding models, quality of content, and research agendas. Addressing these concerns while creating patient-centred, patient-powered online support networks will help leverage these platforms to complement traditional healthcare delivery models in the current environment of value-based care.

    2011-03-01

    Full Text Available In the past years, global access to information has become available at all time through different network architectures and computers for an ever-changing target of employees, suppliers, and clients. In thissense, Internet has been defining the latest trends for the online companies and their customers. Together with the growth of the role that Internet plays in the continuous extending of the online environment as a potential for business, also increased the chances of online malicious attacks and intrusions. They all have at their basis the stealing of user’s identity. User names and passwords areweak and can always be cracked with a little effort from the attacker's side. Users credentials can be phished, stolen, discovered and hacked in multiple ways. In order to contra-attack the new growingthreats, efficient, rapid and reliable means for an automatic recognition of the identity of online users are being developed. Biometric security systems enable more secure authentication methods to access a computer's resources. This paper basically presents a developing biometric access control measure: computer access via keystroke pattern recognition and discusses its direct connection to preventing electronic identity thefts.

The present study examines particular factors that influence the attitude of potential consumers to purchase online by using the attributes from the diffusion of innovations theory of Rogers, the attribute of perception of risk, and the subjective norms toward online purchasing. Consumers’ perceived risks of online shopping have become a vital subject in research because they directly influence users’ attitude toward online purchasing. The structural equation modeling method was used to analyze the data gathered on students using e-commerce, and, thus, to validate the model. According to the results, consumers’ attitude toward online purchasing affects the intention toward online purchasing. The other influential factors are compatibility, relative advantage, and subjective norm.

    Science.gov (United States)

    Douma, M.

    2009-12-01

    Presenting the complexity of geosciences to the public via the Internet poses a number of challenges. For example, utilizing various - and sometimes redundant - Web 2.0 tools can quickly devour limited time. Do you tweet? Do you write press releases? Do you create an exhibit or concept map? The presentation will provide participants with a context for utilizing Web 2.0 tools by briefly highlighting methods of online scientific communication across several dimensions. It will address issues of: * breadth and depth (e.g. from narrow topics to well-rounded views), * presentation methods (e.g. from text to multimedia, from momentary to enduring), * sources and audiences (e.g. for experts or for the public, content developed by producers to that developed by users), * content display (e.g. from linear to non-linear, from instructive to entertaining), * barriers to entry (e.g. from an incumbent advantage to neophyte accessible, from amateur to professional), * cost and reach (e.g. from cheap to expensive), and * impact (e.g. the amount learned, from anonymity to brand awareness). Against this backdrop, the presentation will provide an overview of two methods of online information dissemination, exhibits and concept maps, using the WebExhibits online museum (www.webexhibits.org) and SpicyNodes information visualization tool (www.spicynodes.org) as examples, with tips on how geoscientists can use either to communicate their science. Richly interactive online exhibits can serve to engage a large audience, appeal to visitors with multiple learning styles, prompt exploration and discovery, and present a topic’s breadth and depth. WebExhibits, which was among the first online museums, delivers interactive information, virtual experiments, and hands-on activities to the public. While large, multidisciplinary exhibits on topics like “Color Vision and Art” or “Calendars Through the Ages” require teams of scholars, user interface experts, professional writers and editors

  16. The changing information environment for nanotechnology: online audiences and content.

    Anderson, Ashley A; Brossard, Dominique; Scheufele, Dietram A

    2010-05-01

    The shift toward online communication in all realms, from print newspapers to broadcast television, has implications for how the general public consumes information about nanotechnology. The goal of this study is threefold: to investigate who is using online sources for information and news about science and nanotechnology, to examine what the general public is searching for online with regards to nanotechnology, and to analyze what they find in online content of nanotechnology. Using survey data, we find those who report the Internet as their primary source of science and technology news are diverse in age, more knowledgeable about science and nanotechnology, highly educated, male, and more diverse racially than users of other media. In a comparison of demographic data on actual visits by online users to general news and science Web sites, science sites attracted more male, non-white users from the Western region of the United States than news sites did. News sites, on the other hand, attracted those with a slightly higher level of education. Our analysis of published estimates of keyword searches on nanotechnology reveals people are turning to the Internet to search for keyword searches related to the future, health, and applications of nanotechnology. A content analysis of online content reveals health content dominates overall. Comparisons of content in different types of sites-blogs, government, and general sites-are conducted. ELECTRONIC SUPPLEMENTARY MATERIAL: The online version of this article (doi:10.1007/s11051-010-9860-2) contains supplementary material, which is available to authorized users.

  19. Online Cake Cutting (published version)

    CERN Document Server

    Walsh, Toby

    2011-01-01

    We propose an online form of the cake cutting problem. This models situations where agents arrive and depart during the process of dividing a resource. We show that well known fair division procedures like cut-and-choose and the Dubins-Spanier moving knife procedure can be adapted to apply to such online problems. We propose some fairness properties that online cake cutting procedures can possess like online forms of proportionality and envy-freeness. We also consider the impact of collusion between agents. Finally, we study theoretically and empirically the competitive ratio of these online cake cutting procedures. Based on its resistance to collusion, and its good performance in practice, our results favour the online version of the cut-and-choose procedure over the online version of the moving knife procedure.

    In the fields of power conversion devices and broadcasting/communication amplifiers, high power, high frequency and low losses are desirable. Further, for electronic elements in aerospace/aeronautical/geothermal surveys, etc., heat resistance to 500degC is required. Devices which respond to such hard specifications are called hard electronic devices. However, with Si which is at the core of the present electronics, the specifications cannot fully be fulfilled because of the restrictions arising from physical values. Accordingly, taking up new device materials/structures necessary to construct hard electronics, technologies to develop these to a level of IC were examined and studied. They are a technology to make devices/IC of new semiconductors such as SiC, diamond, etc. which can handle higher temperature, higher power and higher frequency than Si and also is possible of reducing losses, a technology to make devices of hard semiconducter materials such as a vacuum microelectronics technology using ultra-micro/high-luminance electronic emitter using negative electron affinity which diamond, etc. have, a technology to make devices of oxides which have various electric properties, etc. 321 refs., 194 figs., 8 tabs.

  9. Online Distributed Sensor Selection

    CERN Document Server

    Golovin, Daniel; Krause, Andreas

    2010-01-01

    A key problem in sensor networks is to decide which sensors to query when, in order to obtain the most useful information (e.g., for performing accurate prediction), subject to constraints (e.g., on power and bandwidth). In many applications the utility function is not known a priori, must be learned from data, and can even change over time. Furthermore for large sensor networks solving a centralized optimization problem to select sensors is not feasible, and thus we seek a fully distributed solution. In this paper, we present Distributed Online Greedy (DOG), an efficient, distributed algorithm for repeatedly selecting sensors online, only receiving feedback about the utility of the selected sensors. We prove very strong theoretical no-regret guarantees that apply whenever the (unknown) utility function satisfies a natural diminishing returns property called submodularity. Our algorithm has extremely low communication requirements, and scales well to large sensor deployments. We extend DOG to allow observatio...

In Switzerland over 80 % of young people own a smartphone and "pocket internet". Time of interaction with online-media (hours/day), as well as peer group pattern are markers for risk of addiction. Active music making and sports are protective factors. Family physicians are important in early recognition of "internet addictive disease". Care-givers with special experience in this field are often successful in reducing time of harmful interaction with the internet. Internet addictive disease is not yet classified in ICD and DSM-5 lists, even though it is an increasing reality.

Hundreds of thousands care about scientific research and take a long time to select suitable papers for their research. Online reviews on papers are the essential source to help them. The reviews save reading time and save papers cost. This paper proposes a new technique to analyze online reviews. It is called sentiment analysis of online papers (SAOOP. SAOOP is a new technique used for enhancing bag-of-words model, improving the accuracy and performance. SAOOP is useful in increasing the understanding rate of review's sentences through higher language coverage cases. SAOOP introduces solutions for some sentiment analysis challenges and uses them to achieve higher accuracy. This paper also presents a measure of topic domain attributes, which provides a ranking of total judging on each text review for assessing and comparing results across different sentiment techniques for a given text review. Finally, showing the efficiency of the proposed approach by comparing the proposed technique with two sentiment analysis techniques. The comparison terms are based on measuring accuracy, performance and understanding rate of sentences.

    Hard material technologies were surveyed to establish the hard electronic technology which offers superior characteristics under hard operational or environmental conditions as compared with conventional Si devices. The following technologies were separately surveyed: (1) The device and integration technologies of wide gap hard semiconductors such as SiC, diamond and nitride, (2) The technology of hard semiconductor devices for vacuum micro- electronics technology, and (3) The technology of hard new material devices for oxides. The formation technology of oxide thin films made remarkable progress after discovery of oxide superconductor materials, resulting in development of an atomic layer growth method and mist deposition method. This leading research is expected to solve such issues difficult to be easily realized by current Si technology as high-power, high-frequency and low-loss devices in power electronics, high temperature-proof and radiation-proof devices in ultimate electronics, and high-speed and dense- integrated devices in information electronics. 432 refs., 136 figs., 15 tabs.

    Many companies have launched their products or services online as a new business focus, but only a few of them have survived the competition and made profits. The most important key to an online business's success is to create "brand value" for the customers. Although the concept of online brand has been discussed in previous studies, there is no empirical study on the measurement of online branding. As Web 2.0 emerges to be critical to online branding, the purpose of this study was to measure Taiwan's major Web sites with a number of personality traits to build a perceptual map for online brands. A pretest identified 10 most representative online brand perceptions. The results of the correspondence analysis showed five groups in the perceptual map. This study provided a practical view of the associations and similarities among online brands for potential alliance or branding strategies. The findings also suggested that brand perceptions can be used with identified consumer needs and behaviors to better position online services. The brand perception map in the study also contributed to a better understanding of the online brands in Taiwan.

With the development of information technology and electronic commerce, the electronic (online booking seems to be a popular way to facilitate access to certain goods and tourism services via the Internet. The literature clearly indicates that online booking vacations, transportation and other services related to tourism package developed and diversified nearly at the same degree with advances made in Information Technology and Communication (ITC. However, “there are wide variations in online usage levels between different countries … Australian’s online usage is 44 % and Spain’s online usage is 14% from all transactions” [online-booking from WCT]. Regarding the consumer profile using 'online booking ', the literature does not provide a generally accepted set of evaluation attributes. In the world is talking today about "Generation Y", in other words about those who have reached maturity in the early millennium. Basically it's about consumers born between 1980 and 1995, hence with ages between 18 and 33 years. In this context, in our exploratory research we conducted a statistical study on students, tomorrow's economic specialists with knowledge in ITC from minimal to advanced levels. The hypothesis of the study are: a. Humans with advanced computer skills using the Internet for booking holidays; b. Humans with low ITC skills choose the classical method of booking holidays by contacting a tour company. The results of our survey showed that the choice of online tools for booking holidays becomes an increasingly used method in Romania but consumers still lack confidence in the online environment. This phenomenon often motivates the consumers to contact a tour company regardless of their ITC skills or travel experience. We also proved that there is no strong connection between people with good ITC

    Online identities play a critical role in the social web that is taking shape on the Internet. Despite many technical proposals for creating and managing online identities, none has received widespread acceptance. Design and implementation of online identities that are socially acceptable on the Internet remains an open problem. This chapter discusses the interplay between online identities and social networking. Online social networks (OSNs) are growing at a rapid pace and has millions of members in them. While the recent trend is to create explicit OSNs such as Facebook and MySpace, we also have implicit OSNs such as interaction graphs created by email and instant messaging services. Explicit OSNs allow users to create profiles and use them to project their identities on the web. There are many interesting identity related issues in the context of social networking including how OSNs help and hinder the definition of online identities.

The linked data does not answer this question, however, and instead supplies figures on what types of sessions respondents had attended in the past (44.4% attended library instruction sessions, while others were self-taught, consulted colleagues, attended seminars, or obtained skills through their PhD research.Conclusion – Strong public interest in nutritional issues is a growing trend in the Western world. For those faculty members and scholars researching and teaching on nutrition and related areas, more work on their information needs is required. This study begins to address that gap and found that nutrition, food science, and dietetics faculty share strong similarities with researchers in medicine and the other basic sciences with regard to information needs and behaviours. The focus is on electronic journals, PubMed/Medline, and online access to resources. Important insights include the fact that print journals are still in modest use, researchers use grey literature (e.g., government sources and other non-traditional formats (e.g., conference proceedings and electronic mail lists as information sources, and training sessions need to be offered in a variety of formats in order to address individual preferences.

  2. Citizen Goals Online

    Directory of Open Access Journals (Sweden)

    Catalin Vrabie

    2013-01-01

    Full Text Available The purpose of this paper is to give to public institution Web designers a better understanding of the citizens’ objectives when accessing a Web page. Understanding citizen online goals is critical because it gets to the heart of what the public institution website should or could “do.” Approach: The challenge for e-marketers is that for most agencies/institutions, there are likely to be multiple goals that represent the “reason why” citizens could come to the website. For example, a national theatre website might be very effective for people who have already been there, they know effectively what place is the best, who are the actors, etc. Research limitations: The nature of a public institution activity almost dictates the different types of goals that consumers have when visiting the site. It is clear that a citizen has a different goal when accessing a theatre Web page or when he’s accessing a municipality Web page. This is the biggest impediment for drawing a good conceptual model for a public institution Web page. Practical implications: there are likely to be many other goals that could lead people to visit the site, like receiving customer service or leaving a remark. Value: Since citizen online goals represent the starting point for Web design efforts (for public institutions, this article has attempted to highlight the nature and types of goals that e-marketers might consider when planning what their website should do in order to create. Findings: The goal a site visitor has when arriving at a website tends to be very action oriented. If the visitor has never visited the site before, the goal may simply be to evaluate the website and figure out what the site is and if it will help him. On the other hand, if the visitor has reached the site as the result of a directed search or is a repeat visitor, the user goal is likely to be specific and functional. If important citizen goals are not supported by the website, the public

    Traditional large lecture classes are fundamentally passive and teacher-centered. Most existing online courses are as well, including massive open online courses (MOOCs). Research tells us that this mode of instruction is not ideal for student learning. However, the unique attributes of the online environment have thus far been mostly underutilized. We hypothesize that new tools and the innovative curricula they enable can foster greater student engagement and enhance learning at large scale. To test this hypothesis, over the past three years, Arizona State University developed and offered "Habitable Worlds", an online-only astrobiology lab course. The course curriculum is based on the Drake Equation, which integrates across disciplines. The course pedagogy is organized around a term-long, individualized, game-inspired project in which each student must find and characterize rare habitable planets in a randomized field of hundreds of stars using concepts learned in the course. The curriculum allows us to meaningfully integrate concepts from Earth, physical, life, and social sciences in order to address questions related to the possibility of extraterrestrial life. The pedagogy motivates students to master concepts, which are taught through interactive and adaptive inquiry-driven tutorials, featuring focused feedback and alternative pathways that adjust to student abilities, built using an intelligent tutoring system (Smart Sparrow's Adaptive eLearning Platform - AeLP). Through the combination of the project and tutorials, students construct knowledge from experience, modeling the authentic practice of science. Because the tutorials are self-grading, the teaching staff is free to dedicate time to more intense learner-teacher interactions (such as tutoring weaker students or guiding advanced students towards broader applications of the concepts), using platforms like Piazza and Adobe Connect. The AeLP and Piazza provide robust data and analysis tools that allow us to

  6. Trust and Online Reputation Systems

    Kwan, Ming; Ramachandran, Deepak

    Web 2.0 technologies provide organizations with unprecedented opportunities to expand and solidify relationships with their customers, partners, and employees—while empowering firms to define entirely new business models focused on sharing information in online collaborative environments. Yet, in and of themselves, these technologies cannot ensure productive online interactions. Leading enterprises that are experimenting with social networks and online communities are already discovering this fact and along with it, the importance of establishing trust as the foundation for online collaboration and transactions. Just as today's consumers must feel secure to bank, exchange personal information and purchase products and services online; participants in Web 2.0 initiatives will only accept the higher levels of risk and exposure inherent in e-commerce and Web collaboration in an environment of trust. Indeed, only by attending to the need to cultivate online trust with customers, partners and employees will enterprises ever fully exploit the expanded business potential posed by Web 2.0. But developing online trust is no easy feat. While various preliminary attempts have occurred, no definitive model for establishing or measuring it has yet been established. To that end, nGenera has identified three, distinct dimensions of online trust: reputation (quantitative-based); relationship (qualitative-based) and process (system-based). When considered together, they form a valuable model for understanding online trust and a toolbox for cultivating it to support Web 2.0 initiatives.

    Full Text Available Online electronic education is now being widely accepted as a major viable component of higher education. This is fuelled by the emergence of worldwide information and computer communications technologies. However, online education is not being adopted in science and engineering subjects as widely as in other fields because of the idiosyncrasies of some science and engineering-based courses. For online engineering education to be broadly accepted and utilized, the quality of online courses must, amongst other things, be comparable to or better than those of traditional face-to-face classroom education. This paper explores and reports on the importance of creating multimedia-rich course content and the important role that animations can play in creating a successful online learning experience. Results of our study on an online data structures course over five years offerings show that students consistently perform much better in questions requiring application of material taught in carefully animated algorithms. These results should carry over to other educational environments.

    Full Text Available The new information technology is becoming an important factor in the future development of financial services industry, and especially banking industry. Growing international trading and problems in transferring money have motivated researchers to introduce a new structure. Online banking is the newest delivery channel for retail banking services. Online banking facilitated by various Electronic Commerce technologies, has helped commercial banks to stay competitive through productivity gains, transaction cost reduction and customer service improvement. Security for online banking has changed considerably during the relatively short period that online banking has been in use. In particular, authentication in the early implementations was, and sometimes still is, vulnerable to various attacks such as phishing. It is known that the quantum cryptography protocols are able to detect immediately any attempt to attack the key exchange and the authentication process. This paper presentsan introduction of online banking and quantum cryptography. In this paper we are proposing a model for authentication in online banking system with quantum cryptography.

  12. Understanding patient e-loyalty toward online health care services.

    2013-01-01

    Public health institutions are making a great effort to develop patient-targeted online services in an attempt to enhance their effectiveness and reduce expenses. However, if patients do not use those services regularly, public health institutions will have wasted their limited resources. Hence, patients' electronic loyalty (e-loyalty) is essential for the success of online health care services. In this research, an extended Technology Acceptance Model was developed to test e-loyalty intent toward online health care services offered by public health institutions. Data from a survey of 256 users of online health care services provided by the public sanitary system of a region in Spain were analyzed. The research model was tested by using the structural equation modeling approach. The results obtained suggest that the core constructs of the Technology Acceptance Model (perceived usefulness, ease of use, and attitude) significantly affected users' behavioral intentions (i.e., e-loyalty intent), with perceived usefulness being the most decisive antecedent of affective variables (i.e., attitude and satisfaction). This study also reveals a general support for patient satisfaction as a determinant of e-loyalty intent in online health care services. Policy makers should focus on striving to get the highest positive attitude in users by enhancing easiness of use and, mainly, perceived usefulness. Because through satisfaction of patients, public hospitals will enlarge their patient e-loyalty intent, health care providers must always work at obtaining satisfied users and to encourage them to continue using the online services.

    Ying, Yiming; Zhou, Ding-Xuan

    2016-04-01

    Pairwise learning usually refers to a learning task that involves a loss function depending on pairs of examples, among which the most notable ones are bipartite ranking, metric learning, and AUC maximization. In this letter we study an online algorithm for pairwise learning with a least-square loss function in an unconstrained setting of a reproducing kernel Hilbert space (RKHS) that we refer to as the Online Pairwise lEaRning Algorithm (OPERA). In contrast to existing works (Kar, Sriperumbudur, Jain, & Karnick, 2013 ; Wang, Khardon, Pechyony, & Jones, 2012 ), which require that the iterates are restricted to a bounded domain or the loss function is strongly convex, OPERA is associated with a non-strongly convex objective function and learns the target function in an unconstrained RKHS. Specifically, we establish a general theorem that guarantees the almost sure convergence for the last iterate of OPERA without any assumptions on the underlying distribution. Explicit convergence rates are derived under the condition of polynomially decaying step sizes. We also establish an interesting property for a family of widely used kernels in the setting of pairwise learning and illustrate the convergence results using such kernels. Our methodology mainly depends on the characterization of RKHSs using its associated integral operators and probability inequalities for random variables with values in a Hilbert space.

    2015-12-01

    Full Text Available Barter is the direct exchange of goods or services without using a medium of exchange, such as money. Barter faced a number of limitations, and according to Smith (1776, these limitations led to the emergence of money. However, trading with money also exposes traders to the problems of monetary economy such as inflation, deflation, currency de-valuation, and currency exchange fluctuation. According to Statista.com (2015, in 2016, global Business to Customer (B2C e-commerce sales will reach 1.92 trillion US dollars. On the other hand, online barter solutions are rare on the market. The only attempts to tackle online barter are mobile applications, carried out by small businesses. The market gap is caused by the unsolved inefficiencies of barter. The aim of this thesis is to identify the problems of barter, propose an IT solution for the problems of barter, and finally, produce an artefact, which is the realisation of the proposed IT solution by utilising computer systems and computer algorithms.

    2008-07-01

    The purpose of this study was to determine how a traditional weight training class compared to nontraditional classes that were heavily laden with technology. Could students learn resistance exercises by watching video demonstrations over the Internet? Three university weight training classes, each lasting 16 weeks, were compared. Each class had the same curriculum and workout requirements but different attendance requirements. The online group made extensive use of the Internet and was allowed to complete the workouts on their own at any gym that was convenient for them. Seventy-nine college-aged students were randomized into 3 groups: traditional (n = 27), hybrid (n = 25), and online (n = 27). They completed pretest and posttest measures on upper-body strength (i.e., bench press), lower-body strength (i.e., back squat), and knowledge (i.e., written exam). The results indicated that all 3 groups showed significant improvement in knowledge (p students to attend class and may have resulted in significantly lower scores on the bench press (p motivation, low accountability, and the possibility that the self-reported workouts were not accurate. These results suggest that there is a limit to how much technology can be used in a weight training class. If this limit is exceeded, some type of monitoring system appears necessary to ensure that students are actually completing their workouts.

    Online neuropsychological test batteries could allow for large-scale cognitive data collection in clinical studies. However, the few online neuropsychological test batteries that are currently available often still require supervision or lack proper psychometric evaluation. In this paper, we have outlined prerequisites for proper development and use of online neuropsychological tests, with the focus on reliable measurement of cognitive function in an unmonitored setting. First, we identified several technical, contextual, and psychological factors that should be taken into account in order to facilitate reliable test results of online tests in the unmonitored setting. Second, we outlined a methodology of quality assurance needed in order to obtain reliable cognitive data in the long run. Based on factors that distinguish the online unmonitored test setting from the traditional face-to-face setting, we provide a set of basic requirements and suggestions for optimal development and use of unmonitored online neuropsychological tests, including suggestions on acquiring reliability, validity, and norm scores. When properly addressing factors that could hamper reliable test results during development and use, online neuropsychological tests could aid large-scale data collection for clinical studies in the future. Investment in both proper development of online neuropsychological test platforms and the performance of accompanying psychometric studies is currently required.

    Full Text Available Learning and teaching online imposes certain challenges on both students and teachers. Teachers should be prepared to meet special requirements of teaching online. Teachers play an important role in teaching. Roles of teachers increase with introducing the online learning, contrary to an early assumption perceived with the invention of the Internet. Designing and developing online courses need collaboration of several people with a variety of interests and expertise, including administrators, teachers, designers, and technical specialists. Each course within the curriculum should be well-designed and fit well within the curriculum. The curriculum in turn should reflect the current state of the discipline, enabling the learners to develop appropriate proficiency and mastery within the specific discipline. This paper describes the roles of teachers and administrators in online learning, and discusses the rules of best practices for both.

  9. Ethics in Online Publications.

    Science.gov (United States)

    Vervaart, Peter

    2014-10-01

    Journals have been publishing the results of scientific investigations since the founding of Philosophical Transactions in 1665. Since then we have witnessed a massive expansion in the number of journals to the point that there are now approximately 28,000 active, peer reviewed journals collectively publishing more than 1.8 million articles per year. Before the mid-1990s, these journals were only available on paper but by the end of the 20th century, most journals had moved to online platforms. Online publication has also served as the impetus for the move to 'open-access' to the information contained in journals. The fact that a publication is 'on-line' and 'open-access' does not negate the responsibility of the author and the publisher to publish in an ethical way. [1] The document produced by the IFCC Ethics Task Force (TF-E) on publication ethics states that 'Ethics in Science at its broadest level encompasses research ethics, medical ethics, publication ethics, conflicts of interest, ethical responsibilities as educator, plus many other areas.' Thus publication ethics is a continuum from the first step of research design through to the information being read by the reader. In general terms 'publication ethics' includes the ethical behaviour of the authors in writing and submitting a scientific manuscript to a publisher for the purpose of publication, thus any discussion of publication ethics must include the role of the authors, referees, publisher and reader and the issues of authorship (and the use of 'ghosts'), plagiarism, duplicate publication (including in different languages), image manipulation (particularly in the era of digitisation), and conflict of interest [2]. To aid the authors, and others involved in the process of publication, a number of resources are now available particularly those from the Committee on Publication Ethics (COPE) [3] and the World Association of Medical Editors (WAME) [4]. More recently the issue of 'publisher ethics' has

    Søndergaard, Helle Alsted; Bergenholtz, Carsten; Juhl, Hans Jørn

    Extant studies have shown how online communities can promote collaborative and innovative activities in general. Studies on university-industry collaborations have so far focused less on online activities. We therefore set out to examine the individual and organizational drivers and barriers...... for academics and industrial professionals to contribute to online community-based platforms. We use a mixed method approach using both survey data and in-depth interviews with respondents from the Danish food sector. Findings show that in line with known studies on online innovation communities in general......, the main drivers for engagement are organizational and individual learning, and establishing connections, rather than monetary incentives. In contrast to offline studies on university-industry interactions, well-connected academics are less interested in online communities of academics and industry...

    light on the formation, growth, and dissolution of online anti-brand herds. First we expand on the concept of environmental turbulence to advance core properties unique to online herd behavior. Next, based on evidence gathered from 40 online anti-brand herd episodes targeting two prominent firms from...... the Netherlands, we develop an analytical model to investigate drivers of herd formation, growth, and dissolution. Finally, combining environmental turbulence literature with our empirical findings, we derive a novel typology of online anti-brand herd behaviors, and put forward six propositions to guide theory......The online environment offers a fertile breeding ground for anti-brand herds of disgruntled consumers. Firms are often caught off guard by the unpredictability of such herds and, as a consequence, are forced into a reactive, defensive stance. We conduct a social media analysis that aims to shed...

    2008-12-01

    Institutions of higher education are now using Internet-based technology tools to conduct surveys for data collection. Research shows that the type and quality of responses one receives with online surveys are comparable with what one receives in paper-based surveys. Data collection can take place on Web-based surveys, e-mail-based surveys, and personal digital assistants/Smartphone devices. Web surveys can be subscription templates, software packages installed on one's own server, or created from scratch using Web programming development tools. All of these approaches have their advantages and disadvantages. The survey owner must make informed decisions as to the right technology to implement. The correct choice can save hours of work in sorting, organizing, and analyzing data.

  18. Flirting in Online Dating

    DEFF Research Database (Denmark)

    Mortensen, Kristine Køhler

    2017-01-01

    Various fields have examined the activity of flirting, predominantly based on experimental and reported data; the interactional workings are therefore often overlooked. Based on emails and chats from two Danish online dating sites, this article investigates how users negotiate romantic connections...... through the flirting strategy of ‘imagined togetherness’, linguistically constructing imagery of a shared future. Using the notion of the chronotope (Bakhtin 1981), turn-by-turn analysis demonstrates how users, embedded in the activity of getting to know each other, tenuously communicate romantic interest...... by alluding to future points at which they might be together. Central to the strategy is a sequential pattern of avoiding closure and thereby preserving the imagery’s implicitness. The article concludes by arguing that while imagined togetherness functions a way of probing interests and thus protecting...

    2007-01-01

    As organizations search for more secure authentication methods for user access, e-commerce, and other security applications, biometrics is gaining increasing attention. With an increasing emphasis on the emerging automatic personal identification applications, fingerprint based identification is becoming more popular. The most widely used fingerprint representation is the minutiae based representation. The main drawback with this representation is that it does not utilize a significant component of the rich discriminatory information available in the fingerprints. Local ridge structures cannot be completely characterized by minutiae. Also, it is difficult quickly to match two fingerprint images containing different number of unregistered minutiae points. In this study filter bank based representation, which eliminates these weakness, is implemented and the overall performance of the developed system is tested. The results have shown that this system can be used effectively for secure online verification applications.

  9. Efficient Electronic Payment Fit for Wireless Network

    Institute of Scientific and Technical Information of China (English)

    HUANGZheng; CHENKefei; ZHENGDong

    2004-01-01

    David Chaum and Stefan Brands have proposed famous electronic cash schemes. Both schemes offer multi-party security as well as unconditional privacy of payments. We can see that Brands has managed to design a new kind of payment system without the inefficient features of Chaum's electronic cash while still matching most of the requirements placed on electronic cash. Brands' scheme uses simpler signature mechanisms,shorter messages and has smaller storage requirements,which make it very easy and feasible to implement in a wireless network. Both Chaum and Brands' electronic cash schemes are off-line electronic schemes. Unfortunately, to prevent Double-Spending from happening, the security of Brands' scheme relies heavily on the tamper-resistance device. The best way to prevent Double-Spending is to use some kind of on-line system.The on-line electronic payment system has been criticized mostly for its cost inefficiency and its inconvenience. But with the high developing speed of mobile techniques, many people like to use their mobile phone to navigate the Internet or send short messages, for example, NTT's Docomo.People nowadays like to be on-line everywhere and it is a trivial thing to require the user to be on-line when doing the electronic payment in the near future. This paper introduces an electronic payment system that implements Brands' efficient technology (restrictive blinding signature) into the user's mobile phone or user's PDA. The system is very efficient because of using restrictive blinding signature scheme and offers multi-party security as well as unconditional privacy of payments. This system has some features of on-line system, so it can prevent double-spending from happening.

  10. A last updating evolution model for online social networks

    2013-05-01

    As information technology has advanced, people are turning to electronic media more frequently for communication, and social relationships are increasingly found on online channels. However, there is very limited knowledge about the actual evolution of the online social networks. In this paper, we propose and study a novel evolution network model with the new concept of “last updating time”, which exists in many real-life online social networks. The last updating evolution network model can maintain the robustness of scale-free networks and can improve the network reliance against intentional attacks. What is more, we also found that it has the “small-world effect”, which is the inherent property of most social networks. Simulation experiment based on this model show that the results and the real-life data are consistent, which means that our model is valid.

    The online book order request, which is an enlarged inquiring subsystem of TULIPS, started its service of accepting order request in online from terminals outside the library and started in October 1987. Its structure consists of four parts; duplicate checking, record making, cancellation and record display. Through duplicate checking, it is possible to retrieve holding and ordering information at the same time, and by record making we can make use of bibliographic data in JAPAN-MARC or LC-MARC. This function corresponds to various types of terminals on campus and fully automates office documents. Integrating information retrieval and electronic mail system, this online service supplies the end users the information about the availability of materials and current status of requests in a rapid, precise and paperless form.

It performs two calls to the underlying block cipher per plaintext block and is fully parallelizable in both encryption and decryption. COPE is proven secure against chosenplaintext attacks assuming the underlying block......Online ciphers encrypt an arbitrary number of plaintext blocks and output ciphertext blocks which only depend on the preceding plaintext blocks. All online ciphers proposed so far are essentially serial, which significantly limits their performance on parallel architectures such as modern general...

  1. Anonymity versus privacy: selective information sharing in online cancer communities.

    Science.gov (United States)

    Frost, Jeana; Vermeulen, Ivar E; Beekers, Nienke

    2014-05-14

    Active sharing in online cancer communities benefits patients. However, many patients refrain from sharing health information online due to privacy concerns. Existing research on privacy emphasizes data security and confidentiality, largely focusing on electronic medical records. Patient preferences around information sharing in online communities remain poorly understood. Consistent with the privacy calculus perspective adopted from e-commerce research, we suggest that patients approach online information sharing instrumentally, weighing privacy costs against participation benefits when deciding whether to share certain information. Consequently, we argue that patients prefer sharing clinical information over daily life and identity information that potentially compromises anonymity. Furthermore, we explore whether patients' prior experiences, age, health, and gender affect perceived privacy costs and thus willingness to share information. The goal of the present study is to document patient preferences for sharing information within online health platforms. A total of 115 cancer patients reported sharing intentions for 15 different types of information, demographics, health status, prior privacy experiences, expected community utility, and privacy concerns. Factor analysis on the 15 information types revealed 3 factors coinciding with 3 proposed information categories: clinical, daily life, and identity information. A within-subject ANOVA showed a strong preference for sharing clinical information compared to daily life and identity information (F1,114=135.59, P=.001, η(2)=.93). Also, adverse online privacy experiences, age, and health status negatively affected information-sharing intentions. Female patients shared information less willingly. Respondents' information-sharing intentions depend on dispositional and situational factors. Patients share medical details more willingly than daily life or identity information. The results suggest the need to focus on

    2016-10-01

    As increasing numbers of students enroll in online education, institutions of higher education are responsible for delivering quality online courses and programs. Agencies that accredit institutions and programs require evidence of program quality, including student satisfaction. A large state university in the Southeastern United States transitioned an online nursing education degree completion, or Registered Nurse-to-Bachelor of Science in Nursing, program to an online accelerated format in order to meet the needs of working nurses and ultimately, increase the number of nurses prepared at the baccalaureate level. This article describes a descriptive, cross-sectional study that evaluated the effectiveness of the new online accelerated program using the quality indicator of student satisfaction. Ninety-one (32%) of the 284 students who were enrolled or had been enrolled in a course within the online accelerated degree completion program between fall 2013 session 1 and summer 2014 session participated in the study. The electronic Noel-Levitz Priorities Survey for Online Learners™ was used to measure student satisfaction with the program and associated services. Results provided insight into the students' satisfaction with the new program format and served as the basis for an interdepartmental program enhancement plan aimed at maintaining and enhancing student satisfaction and overall program quality. Findings indicated that measuring and evaluating student satisfaction can provide valuable information about the effectiveness of an online program. Recommendations for using the measurement tool in online program planning and studying student satisfaction in relation to retention and program completion were identified.

  6. Access to IEEE Electronic Library

    CERN Multimedia

    2007-01-01

    From 2007, the CERN Library now offers readers online access to the complete IEEE Electronic Library (Institute of Electrical and Electronics Engineers). This new licence gives unlimited online access to all IEEE and IET (previously IEE) journals and proceedings as well as all current IEEE standards and selected archived ones. Some of the titles offer volumes back to 1913. This service currently represents more than 1,400,000 full-text articles! This leading engineering information resource replaces the previous service, a sub-product of the IEEE database called 'IEEE Enterprise', which offered online access to the complete collection of IEEE journals and proceedings, but with limited features. The service had become so popular that the CERN Working Group for Acquisitions recommended that the Library subscribe to the complete IEEE Electronic Library for 2007. Usage statistics for recent months showed there was a demand for the service from a large community of CERN users and we were aware that many users h...

  7. Electronic Commerce "in the dark"

    Science.gov (United States)

    Buzzi, Maria Claudia; Buzzi, Marina; Leporini, Barbara; Senette, Caterina

    The widespread diffusion of electronic commerce offers a great opportunity for blind people. We describe the results of an electronic survey carried out with 22 blind and 22 sighted users in order to understand the difficulties and obstacles they experience shopping on-line, and solicit their expectations and suggestions for making the interaction simpler and more satisfying. Results show that blind users shop on-line much less than their sighted counterparts, since they encounter more difficulties not only when making a purchase, but even in the navigation phase preceding the commercial transaction. Complex layouts and unstructured content can prevent an e-transaction from being successfully completed. Furthermore, security, privacy and trustiness, common concerns for all consumers, also impact on the fear of buying via Internet for the visually impaired. Poor usability leads to a potential loss of revenue for on-line companies and a lost opportunity to increase a blind person's independence. Providing simpler, more understandable UIs would benefit all users and fuel the expansion of electronic commerce.

    2015-01-01

    The article presents and condenses the background, findings and results of a one yearlong research project on online supervision and feedback at the university. The article builds on presentations and discussions in different research environments and conferences on higher education research...... supervision proves unhelpful when trying to understand how online supervision and feedback is a pedagogical phenomenon in its own right, and irreducible to the face-to-face context. Secondly we show that not enough attention has been given to the way different digital tools and platforms influence...... the supervisory dialogue in the specific supervision context. We conclude by terming this challenge in online supervision a form of ‘torn pedagogy’; that online tools and platforms destabilise and ‘tear’ traditional understandings of supervision pedagogy ‘apart’. Also, we conclude that on the backdrop of a torn...

    Grabowski, A.; Kosiński, R. A.

    2010-12-01

    Recently online communities have attracted great interest and have become an important medium of information exchange between users. The aim of this work is to introduce a simple model of the evolution of online communities. This model describes (a) the time evolution of users’ activity in a web service, e.g., the time evolution of the number of online friends or written posts, (b) the time evolution of the degree distribution of a social network, and (c) the time evolution of the number of active users of a web service. In the second part of the paper we investigate the influence of the users’ lifespan (i.e., the total time in which they are active in an online community) on the process of rumor propagation in evolving social networks. Viral marketing is an important application of such method of information propagation.

  15. Stability Conditions for Online Learnability

    CERN Document Server

    Ross, Stephane

    2011-01-01

    Stability is a general notion that quantifies the sensitivity of a learning algorithm's output to small change in the training dataset (e.g. deletion or replacement of a single training sample). Such conditions have recently been shown to be more powerful to characterize learnability in the general learning setting under i.i.d. samples where uniform convergence is not necessary for learnability, but where stability is both sufficient and necessary for learnability. We here show that similar stability conditions are also sufficient for online learnability, i.e. whether there exists a learning algorithm such that under any sequence of examples (potentially chosen adversarially) produces a sequence of hypotheses that has no regret in the limit with respect to the best hypothesis in hindsight. We introduce online stability, a stability condition related to uniform-leave-one-out stability in the batch setting, that is sufficient for online learnability. In particular we show that popular classes of online learners...

    An increasing number of today's social interactions occurs using online social media as communication channels. Some online social networks have become extremely popular in the last decade. They differ among themselves in the character of the service they provide to online users. For instance, Facebook can be seen mainly as a platform for keeping in touch with close friends and relatives, Twitter is used to propagate and receive news, LinkedIn facilitates the maintenance of professional contacts, Flickr gathers amateurs and professionals of photography, etc. Albeit different, all these online platforms share an ingredient that pervades all their applications. There exists an underlying social network that allows their users to keep in touch with each other and helps to engage them in common activities or interactions leading to a better fulfillment of the service's purposes. This is the reason why these platforms share a good number of functionalities, e.g., personal communication channels, broadcasted status...

We measured electronic prescriptions for Plan B (Duramed Pharmaceuticals, Cincinnati, Ohio) by month over time. Pharmacists faxed patient-generated prescriptions back to the Department of Public Health for confirmation. Despite no marketing, within the first 18 months of the program, 152 electronic prescriptions for Plan B were requested by 128 female San Francisco residents. Seventy-eight prescriptions were filled (51%) by pharmacists. If correctly marketed, online prescriptions for Plan B have the potential to be an effective means of increasing emergency contraception access in both urban and rural settings across the United States. Further user-acceptability studies are warranted.

    Full Text Available Internet shopping is one of the main pillars of electronic commerce.According to the literature, the Internet Shopping Optimization Problem (ISOPhas been defined in order to optimize the global cost of online purchase, taking into account both the cost of products and shipping. In this study, it was decided to propose and analyze a very interesting, and really substantial, extension of the ISOP.Namely, trust factors were subjected to careful analysis from the customer point of view. The analysis is based on a specially prepared questionnaire, supplemented by the information from the literature and our own observations. Thus, it was possible to propose a definition of a new mathematical model of the problem, and to prove its affiliation to the class of strongly NP-hard problems. In addition, the heuristic algorithm is proposed, which can be used to solve the problem.
