    Decadal prediction of the coupled climate system is potentially possible given enough information and knowledge. Predictability will reside in both externally forced and in long timescale internally generated variability. The ''potential predictability'' investigated here is characterized by the fraction of the total variability accounted for by these two components in the presence of short-timescale unpredictable ''noise'' variability. Potential predictability is not a classical measure of predictability nor a measure of forecast skill but it does identify regions where long timescale variability is an appreciable fraction of the total and hence where prediction on these scale may be possible. A multi-model estimate of the potential predictability variance fraction (ppvf) as it evolves through the first part of the twenty-first century is obtained using simulation data from the CMIP3 archive. Two estimates of potential predictability are used which depend on the treatment of the forced component. The multi-decadal estimate considers the magnitude of the forced component as the change from the beginning of the century and so becomes largely a measure of climate change as the century progresses. The next-decade estimate considers the change in the forced component from the past decade and so is more pertinent to an actual forecast for the next decade. Long timescale internally generated variability provides additional potential predictability beyond that of the forced component. The ppvf may be expressed in terms of a signal-to-noise ratio and takes on values between 0 and 1. The largest values of the ppvf for temperature are found over tropical and mid-latitude oceans, with the exception of the equatorial Pacific, and some but not all tropical land areas. Overall the potential predictability for temperature generally declines with latitude and is relatively low over mid- to high-latitude land. Potential predictability for

    One of the key components of designing usable and useful collaborative information retrieval systems is to understand the needs of the users of these systems. Our research team has been exploring collaborative information behavior in a variety of organizational settings. Our research goals have been two-fold: First, to develop a conceptual understanding of collaborative information behavior and second, gather requirements for the design of collaborative information retrieval systems. In this paper, we present a brief overview of our fieldwork in a three different organizational settings, discuss our methodology for collecting data on collaborative information behavior, and highlight some lessons that we are learning about potential users of collaborative information retrieval systems in these domains.

    Topical prevention of HIV and other STIs is a global health priority. To provide options for users, developers have worked to design safe, effective and acceptable vaginal dissolving film formulations. We aimed to characterize user experiences of vaginal film size, texture and color, and their role in product-elicited sensory perceptions (i.e. perceptibility), acceptability and willingness to use. In the context of a user-centered product evaluation study, we elicited users' 'first impressions' of various vaginal film formulation designs via visual and tactile prototype inspection during a qualitative user evaluation interview. Twenty-four women evaluated prototypes. Participants considered size and texture to be important for easy insertion. Color was more important following dissolution than prior to insertion. When asked to combine and balance all properties to arrive at an ideal film, previously stated priorities for individual characteristics sometimes shifted, with the salience of some individual characteristics lessening when multiple characteristics were weighted in combination. While first impressions alone may not drive product uptake, users' willingness to initially try a product is likely impacted by such impressions. Developers should consider potential users' experiences and preferences in vaginal film design. This user-focused approach is useful for characterizing user sensory perceptions and experiences relevant to early design of prevention technologies.

    Humans have traditionally cultivated steppe and forest-steppe on fertile soils for agriculture. Forests are predicted to shift northwards in a warmer climate and are likely to be replaced by forest-steppe and steppe ecosystems. We analyzed potential climate change impacts on agriculture in south-central Siberia believing that agriculture in traditionally cold Siberia may benefit from warming. Simple models determining crop range and regression models determining crop yields were constructed and applied to climate change scenarios for various time frames: pre-1960, 1960-90 and 1990-2010 using historic data and data taken from 2020 and 2080 HadCM3 B1 and A2 scenarios. From 50 to 85% of central Siberia is predicted to be climatically suitable for agriculture by the end of the century, and only soil potential would limit crop advance and expansion to the north. Crop production could increase twofold. Future Siberian climatic resources could provide the potential for a great variety of crops to grow that previously did not exist on these lands. Traditional Siberian crops could gradually shift as far as 500 km northwards (about 50-70 km/decade) within suitable soil conditions, and new crops nonexistent today may be introduced in the dry south that would necessitate irrigation. Agriculture in central Siberia would likely benefit from climate warming. Adaptation measures would sustain and promote food security in a warmer Siberia.

    The upper critical level of a potentially toxic element is its minimum concentration in actively growing tissues of a plant at which yield is reduced. The following values for upper critical levels in the leaves and shoots of spring barley at the five-leaf stage were determined by means of sand culture experiments in the glasshouse: Ag 4; As 20; B 80; Ba 500; Be 0.6; Cd 15; Co 6; Cr 10; Cu 20; Hg 3; Li 4; Mo 135; Ni 26; Pb 35; Se 30; Sn 63; Tl 20; V 2; Zn 290; Zr 15 ppm of dry matter. They are presented as the basis of a simple procedure for monitoring harmful accumulations of these elements in the soil environment. The concentrations of simple solutions of these elements which induced toxicity under the conditions of the experiments are also presented. There was little uptake of Bi, Sb and Te even from solutions that reduced the yield of young barley. It is believed that these elements may have reduced the availability or translocation of other nutrient elements.

  14. Agriculture in West Africa in the Twenty-First Century: Climate Change and Impacts Scenarios, and Potential for Adaptation.

    2016-01-01

    West Africa is known to be particularly vulnerable to climate change due to high climate variability, high reliance on rain-fed agriculture, and limited economic and institutional capacity to respond to climate variability and change. In this context, better knowledge of how climate will change in West Africa and how such changes will impact crop productivity is crucial to inform policies that may counteract the adverse effects. This review paper provides a comprehensive overview of climate change impacts on agriculture in West Africa based on the recent scientific literature. West Africa is nowadays experiencing a rapid climate change, characterized by a widespread warming, a recovery of the monsoonal precipitation, and an increase in the occurrence of climate extremes. The observed climate tendencies are also projected to continue in the twenty-first century under moderate and high emission scenarios, although large uncertainties still affect simulations of the future West African climate, especially regarding the summer precipitation. However, despite diverging future projections of the monsoonal rainfall, which is essential for rain-fed agriculture, a robust evidence of yield loss in West Africa emerges. This yield loss is mainly driven by increased mean temperature while potential wetter or drier conditions as well as elevated CO2 concentrations can modulate this effect. Potential for adaptation is illustrated for major crops in West Africa through a selection of studies based on process-based crop models to adjust cropping systems (change in varieties, sowing dates and density, irrigation, fertilizer management) to future climate. Results of the cited studies are crop and region specific and no clear conclusions can be made regarding the most effective adaptation options. Further efforts are needed to improve modeling of the monsoon system and to better quantify the uncertainty in its changes under a warmer climate, in the response of the crops to such

    The paper describes an iterative development process used to understand the suitability of different inclusive design evaluation tools applied into design practices. At the end of this process, a tool named Inclusive Design Advisor was developed, combining data related to design features of small appliances with ergonomic task demands, anthropometric data and exclusion data. When auditing a new design the tool examines the exclusion that each design feature can cause, followed by objective recommendations directly related to its features. Interactively, it allows designers or clients to balance design changes with the exclusion caused. It presents the type of information that enables designers and clients to discuss user needs and make more inclusive design decisions. Copyright © 2017. Published by Elsevier Ltd.

    Objective: To evaluate the antiangiogenic potential of twenty two marine invertebrate species of Phylum Mollusca from south east coast of India.Methods:Live specimens of molluscan species were collected and their methanolic extracts were evaluated for preliminary antiangiogenic activity using the in ovo chick chorio-allantoic membrane assay. The extracts were further evaluated for in vivo antiangiogenic activity using chemical cautery induced corneal neovascularization assay in rats and oxygen induced retinopathy assay in rat pups.Results:In the chick chorio-allantoic membrane assay, four methanolic extracts of marine molluscan species viz. Meretrix meretrix, Meretrix casta, Telescopium telescopium and Bursacrumena methanolic extracts exhibited noticeable antiangiogenic activity at the tested concentration of 200 µg whereby they significantly inhibited the VEGF induced proliferation of new blood vessels. Among these four extracts, the methanolic extract of Meretrix casta exhibited relatively higher degree of antiangiogenic activity with an inhibitiory percentage (64.63%) of the VEGF induced neovascularization followed by the methanolic extracts of Telescopium telescopium (62.02%), Bursa crumena (60.48%) and Meretrix meretrix (47.01%). These four methanolic extracts were further evaluated for in vivo antiangiogenic activity whereby the methanolic extract of Telescopium telescopium exhibited most noticeable inhibition (42.58%) of the corneal neovascularization in rats in comparison to the sham treated group, and also exhibited most noticeable inhibition (31.31%) of the oxygen induced retinal neovascularization in rat pups in comparison to the hyperoxia group that was observed for considerable retinal neovascularization.Conclusions:The significant antiangiogenic activity evinced by the extract of Telescopium telescopium merits further investigation for ocular neovascular diseases.

    Full Text Available Previous studies of mobile payment (m-payment services have primarily focused on a single group of adopters. This study identifies the factors that influence an individual’s intention to use m-payment services and compares groups of current users (adopters with potential users (non-adopters. A research model that reflects the behavioral intention to use m-payment services is developed and empirically tested using structural equation modeling on a data set consisting of 529 potential users and 256 current users of m-payment services in Thailand. The results show that the factors that influence current users’ intentions to use m-payment services are compatibility, subjective norms, perceived trust, and perceived cost. Subjective norms, compatibility, ease of use, and perceived risk influenced potential users’ intentions to use m-payment. Subjective norms and perceived risk had a stronger influence on potential users, while perceived cost had a stronger influence on current users, in terms of their intentions to use m-payment services. Discussions, limitations, and recommendations for future research are addressed.

    The capacity of product form to arouse user's behavioural intention plays a decisive role in further user experience, even in purchase decision, while traditional methods rarely give a fully understanding of user experience evoked by product form, especially the feeling of anticipated use of product. Behavioural intention aroused by product form designs has not yet been investigated electrophysiologically. Hence event related potentials (ERPs) were applied to explore the process of behavioural intention when users browsed different smart phone form designs with brand and price not taken into account for mainly studying the brain activity evoked by variety of product forms. Smart phone pictures with different anticipated user experience were displayed with equiprobability randomly. Participants were asked to click the left mouse button when certain picture gave them a feeling of behavioural intention to interact with. The brain signal of each participant was recorded by Curry 7.0. The results show that pictures with an ability to arouse participants' behavioural intention for further experience can evoke enhanced N300 and LPPs (late positive potentials) in central-parietal, parietal and occipital regions. The scalp topography shows that central-parietal, parietal and occipital regions are more activated. The results indicate that the discrepancy of ERPs can reflect the neural activities of behavioural intention formed or not. Moreover, amplitude of ERPs occurred in corresponding brain areas can be used to measure user experience. The exploring of neural correlated with behavioural intention provide an accurate measurement method of user's perception and help marketers to know which product can arouse users' behavioural intention, maybe taken as an evaluating indicator of product design.

    Full Text Available This study explores the presence and actions of an electronic cigarette (e-cigarette brand, Blu, on Twitter to observe how marketing messages are sent and diffused through the retweet (i.e., message forwarding functionality. Retweet networks enable messages to reach additional Twitter users beyond the sender's local network. We follow messages from their origin through multiple retweets to identify which messages have more reach, and the different users who are exposed.We collected three months of publicly available data from Twitter. A combination of techniques in social network analysis and content analysis were applied to determine the various networks of users who are exposed to e-cigarette messages and how the retweet network can affect which messages spread.The Blu retweet network expanded during the study period. Analysis of user profiles combined with network cluster analysis showed that messages of certain topics were only circulated within a community of e-cigarette supporters, while other topics spread further, reaching more general Twitter users who may not support or use e-cigarettes.Retweet networks can serve as proxy filters for marketing messages, as Twitter users decide which messages they will continue to diffuse among their followers. As certain e-cigarette messages extend beyond their point of origin, the audience being exposed expands beyond the e-cigarette community. Potential implications for health education campaigns include utilizing Twitter and targeting important gatekeepers or hubs that would maximize message diffusion.

    Full Text Available We investigated the potential of a panel of 22 biomarkers to predict the presence of coronary artery disease (CAD in type 2 diabetes mellitus (DM2 patients. The study enrolled 96 DM2 patients with (n = 75 and without (n = 21 evidence of CAD. We assessed a biochemical profile that included 22 biomarkers: total cholesterol, LDL, HDL, LDL/HDL, triglycerides, glucose, glycated hemoglobin, fructosamine, homocysteine, cysteine, methionine, reduced glutathione, oxidized glutathione, reduced glutathione/oxidized glutathione, L-arginine, asymmetric dimethyl-L-arginine, symmetric dimethyl-L-arginine, asymmetric dimethyl-L-arginine/L-arginine, nitrate plus nitrite, S-nitrosothiols, nitrotyrosine, and n-acetyl-β-glucosaminidase. Prediction models were built using logistic regression models. We found that eight biomarkers (methionine, nitratate plus nitrite, n-acetyl-β-glucosaminidase, BMI, LDL, HDL, reduced glutathione, and L-arginine/asymmetric dimethyl-L-arginine along with gender and BMI were significantly associated with the odds of CAD in DM2. These preliminary findings support the notion that emerging biochemical markers might be used for CAD prediction in patients with DM2. Our findings warrant further investigation with large, well-designed studies.

    Although dietary supplements are widely used and generally are considered safe, some supplements have been identified as causative agents for adverse reactions, some of which may even be fatal. The Food and Drug Administration (FDA) is responsible for monitoring supplements and ensuring that supplements are safe. However, current surveillance protocols are not always effective. Leveraging user-generated textual data, in the form of Amazon.com reviews for nutritional supplements, we use natural language processing techniques to develop a system for the monitoring of dietary supplements. We use topic modeling techniques, specifically a variation of Latent Dirichlet Allocation (LDA), and background knowledge in the form of an adverse reaction dictionary to score products based on their potential danger to the public. Our approach generates topics that semantically capture adverse reactions from a document set consisting of reviews posted by users of specific products, and based on these topics, we propose a scoring mechanism to categorize products as "high potential danger", "average potential danger" and "low potential danger." We evaluate our system by comparing the system categorization with human annotators, and we find that the our system agrees with the annotators 69.4% of the time. With these results, we demonstrate that our methods show promise and that our system represents a proof of concept as a viable low-cost, active approach for dietary supplement monitoring.

    Classical empirical potentials/force-fields (FF) provide atomistic insights into material phenomena through molecular dynamics and Monte Carlo simulations. Despite their wide applicability, a systematic evaluation of materials properties using such potentials and, especially, an easy-to-use user-interface for their comparison is still lacking. To address this deficiency, we computed energetics and elastic properties of variety of materials such as metals and ceramics using a wide range of empirical potentials and compared them to density functional theory (DFT) as well as to experimental data, where available. The database currently consists of 3248 entries including energetics and elastic property calculations, and it is still increasing. We also include computational tools for convex-hull plots for DFT and FF calculations. The data covers 1471 materials and 116 force-fields. In addition, both the complete database and the software coding used in the process have been released for public use online (presently at http://www.ctcms.nist.gov/∼knc6/periodic.html) in a user-friendly way designed to enable further material design and discovery.

    Much recent research aims to identify evidence for Drug-Drug Interactions (DDI) and Adverse Drug reactions (ADR) from the biomedical scientific literature. In addition to this "Bibliome", the universe of social media provides a very promising source of large-scale data that can help identify DDI and ADR in ways that have not been hitherto possible. Given the large number of users, analysis of social media data may be useful to identify under-reported, population-level pathology associated with DDI, thus further contributing to improvements in population health. Moreover, tapping into this data allows us to infer drug interactions with natural products-including cannabis-which constitute an array of DDI very poorly explored by biomedical research thus far. Our goal is to determine the potential of Instagram for public health monitoring and surveillance for DDI, ADR, and behavioral pathology at large. Most social media analysis focuses on Twitter and Facebook, but Instagram is an increasingly important platform, especially among teens, with unrestricted access of public posts, high availability of posts with geolocation coordinates, and images to supplement textual analysis. Using drug, symptom, and natural product dictionaries for identification of the various types of DDI and ADR evidence, we have collected close to 7000 user timelines spanning from October 2010 to June 2015.We report on 1) the development of a monitoring tool to easily observe user-level timelines associated with drug and symptom terms of interest, and 2) population-level behavior via the analysis of co-occurrence networks computed from user timelines at three different scales: monthly, weekly, and daily occurrences. Analysis of these networks further reveals 3) drug and symptom direct and indirect associations with greater support in user timelines, as well as 4) clusters of symptoms and drugs revealed by the collective behavior of the observed population. This demonstrates that Instagram

    We have developed a software package based on a genetic algorithm that fits an analytic function to a given set of data points. The code, called GAFit, was also interfaced with the CHARMM and MOPAC programs in order to facilitate force field parameterizations and fittings of specific reaction parameters (SRP) for semiempirical Hamiltonians. The present tool may be applied to a wide range of fitting problems, though it has been especially designed to significantly reduce the hard work involved in the development of potential energy surfaces for complex systems. For this purpose, it has been equipped with several programs to help the user in the preparation of the input files. We showcase the application of the computational tool to several chemical-relevant problems: force-field parameterization, with emphasis on nonbonded energy terms or intermolecular potentials, derivation of SRP for semiempirical Hamiltonians, and fittings of generic analytical functions.

Current reluctance on the part of health authorities is likely due to the lack of existing evidence surrounding the extent of related harm and potential uptake of such a facility among NIDUs in this setting. In November 2004, a feasibility study was conducted among 437 crack cocaine smokers. Univariate analyses were conducted to determine associations with willingness to use a SSF and logistic regression was used to adjust for potentially confounding variables (p

    Smoking is recognized as a health problem worldwide and there is an established tobacco epidemic in Saudi Arabia as in many other countries, with tobacco users at increased risk of developing many diseases. This cross sectional study was conducted to assess the prevalence of oral mucosal, potentially malignant or malignant, lesions associated with tobacco use among a stratified cluster sample of adults in Jeddah, Saudi Arabia. A sample size of 599 was collected and each participant underwent clinical conventional oral examination and filled a questionnaire providing information on demographics, tobacco use and other relevant habits. The most common form of tobacco used was cigarette smoking (65.6 %) followed by Shisha or Moasel (38.1%), while chewing tobacco, betel nuts and gat accounted for 21-2%, 7.7%, and 5% respectively. A high prevalence (88.8%) of soft tissue lesions was found among the tobacco users examined, and a wide range of lesions were detected, about 50% having hairy tongue, 36% smoker's melanosis, 28.9% stomatitis nicotina, 27% frictional keratosis, 26.7% fissured tongue, 26% gingival or periodontal inflammation and finally 20% leukodema. Suspicious potentially malignant lesions affected 10.5% of the subjects, most prevalent being keratosis (6.3%), leukoplakia (2.3%), erythroplakia (0.7%), oral submucous fibrosis (0.5%) and lichenoid lesions (0.4%), these being associated with male gender, lower level of education, presence of diabetes and a chewing tobacco habit. It is concluded that smoking was associated with a wide range of oral mucosal lesions , those suspicious for malignancy being linked with chewable forms, indicating serious effects.

    Purpose: The study intends to examine the factors influencing the behavioral intention to use academic libraries’ mobile systems from the perspective of current users and potential adopters, respectively. Design/methodology/approach: Our study investigates the mobile library system’s acceptance by using a context-specific extension of the theory of reasoned action(TRA) and the technology acceptance model(TAM), which includes such factors as mobile self-efficacy, personal innovativeness and perceived playfulness. Structural equation modeling was used to test the validity of the proposed model based on the empirical data which was collected from 210 questionnaire survey participants.Findings: The result shows that 1) for both current users and potential adopters, attitude toward use and subjective norm both have a significant and positive impact on behavioral intention to use; 2) perceived usefulness and perceived ease of use are significantly correlated to potential adopters’ attitude toward use whereas perceived usefulness and perceived playfulness are significantly related to current users’ attitude toward use; 3) as for the comparison between the two groups of users, personal innovativeness not only affects perceived usefulness of both current users and potential adopters, but also affects potential adopters’ perceived playfulness positively. Mobile self-efficacy has a significant effect on perceived ease of use for both types of users.Research limitations: Although the sample size met the basic statistics requirements for the social research, the participants were mainly college students, and other mobile system users like faculty members and researchers were not investigated. In addition, some influencing factors, such as information quality, system quality and service quality were not considered in the research model.Practical implications: This study reveals main factors which influence both current users and potential adopters’ intention to use

  12. Potential influence of Web 2.0 usage and security practices of online users on information management

    Full Text Available The proliferation of Web 2.0 applications was the impetus for this survey-based research into practices that online users currently employ when using Web 2.0 sites. As part of the study, the popularity of Web 2.0 technologies and sites among online users at a university was investigated to determine the extent of the potential threat to corporate security, arising from Web 2.0 use and access. The results of this study indicate that the use of Web 2.0 sites is very popular among students, as a proxy for the potential future business users, and that users are not necessarily aware of the risks associated with these sites. The respondents indicated that they regularly visit Web 2.0 sites, and that they post personal information on these sites. This is of concern in protecting arguably the most valuable asset of a business.

    The usability of a rapid point-of-care ABO-Rh blood typing kit was determined by comparing the performance of individuals with extensive medical training/experience to those with a lesser extent. Subjects were asked to use the blood typing kit with their own blood. These outcomes were compared to that listed in the subject's medical record, stamped on their dog tag, and the result interpreted by a laboratorian. For all participants, there was ∼80% consistency between the result interpreted by the subject and that stated in their medical record. The participant's level of formal education (P ≤ 0.05) affected the accuracy of the blood typing kit. When comparing the subject's outcome to that stated in their medical record, the performance of individuals in the Medical Corps was approximately 10% and 25% higher (P < 0.05) than that observed with Hospital Corpsman or Medical Service Corps members, respectively. To remove bias that can occur when interpreting the blood type of oneself, the subjects also interpreted the result from cards prepared by the investigator. Taken together, a discrepancy between the potential diagnostic accuracy of the kit and that observed with potential end users was identified.

    The abnormal cognitive processing of drug cues is a core characteristic of drug dependence. Previous research has suggested that the late positive potential (LPP) of heroin users is increased by heroin-related stimuli because of the attention-grabbing nature of such stimuli. The present research used a modified emotional Stroop (eStroop) task to examine whether there was an early posterior negativity (EPN) modulation to heroin cues compared with emotional or neutral stimuli in heroin dependent subjects. Fifteen former heroin users and 15 matched controls performed the eStroop task, which was composed of positive, negative, heroin-related, and neutral pictures with superimposed color squares. Participants responded to the color of the square and not to the picture while behavioral data and event-related potentials were recorded. There were no significant differences of EPN amplitudes to emotional and neutral stimuli between heroin users and controls. However, heroin users displayed increased EPN modulation for heroin cues, whereas this modulation was absent in controls. Drug-related cues acquire motivational salience and automatically capture the attention of heroin users at early processing stages, even when engaged in a non-drug-related task. The EPN to heroin cues could represent a novel electrophysiological index with clinical implications for selecting abstinent drug users who are at increased risk of relapse or to evaluate treatment interventions.

    2016-04-01

    The document describing the particular ionospheric model developed for the Galileo satellite navigation system has been very recently released, the official Ionospheric Correction Algorithm for Galileo Single Frequency Users document (from here on-wards named Galileo-Iono), available at www.gsc-europa.eu/system/files/galileo_documents/Galileo_Ionospheric_Model.pdf. This publication allows GNSS receiver manufacturers to start the implementation of the specific algorithm targeted for their Galileo related products in order to be compliant with the Galileo system. As indicated in the Galileo OS SIS ICD, among the parameters that are broadcast in the Galileo navigation message, parameters that are sent within both F/NAV and I/NAV, one can find five Ionospheric Disturbance Flags for Regions 1 to 5 (SF1, SF2, SF3, SF4 and SF5). Nevertheless, in the current version of the model presented in the Galileo-Iono document, the Ionospheric Disturbance flags are "not used" within the Galileo ionospheric correction calculation. In this work, a potential approach to account for this information is being investigated. This plan includes the update of the Galileo ionospheric, NeQuick-G, correction model by specifying the use of these flags. Hence a customized version of the NeQuick-G model has been developed and tested. Specific scenarios will be considered to test whether this approach of considering the added value information of the Ionospheric Disturbance Flags is translated into the positioning domain. In order to assess the improvement obtained using the proposed approach five stations displaced in the five regions are used. Different days of data have been collected in nominal and disturbed conditions; the evaluation is carried out comparing the performance of the proposed approach with respect to the classical approach. The benefits of the use of the disturbance flags information are evaluated comparing the performance in similar geometry conditions.

    Compare the processing of music-syntactic irregularities and physical oddballs between cochlear implant (CI) users and matched controls. Musical chord sequences were presented, some of which contained functionally irregular chords, or a chord with an instrumental timbre that deviated from the standard timbre. In both controls and CI users, functionally irregular chords elicited early (around 200 ms) and late (around 500 ms) negative electric brain responses (early right anterior negativity,ERAN and N5). Amplitudes of effects depended on the degree of music-syntactic irregularity in both groups; effects elicited in CI users were distinctly smaller than in controls. Physically deviant chords elicited a timbre-mismatch negativity (MMN) and a P3 in both groups, again with smaller amplitudes in CI users. ERAN and N5 (as well as timbre-MMN and P3), can be elicited in CI users. Although amplitudes of effects were considerably smaller in the CI group, the presence of MMN and ERAN indicates that neural mechanisms of both physical and music-syntactic irregularity-detection were active in this group.

    The "Top at Twenty" workshop is dedicated to the celebration of 20 years since the top quark discovery at Fermilab in 1995. Speakers from all experiments capable of studying top quark, ATLAS, CDF, CMS and DZero, will present the most recent results of the top quark studies based on Run II of the Tevatron and Run I of the LHC. Reviews of such fundamental measurements as mass of the top quark, its spin, charge and production properties are planned with some of them orders of magnitude better in precision in comparison with original CDF and DZero papers announcing the top quark discovery. Measurements of top quark production and decay that illuminate the nature of the Higgs boson and seek new phenomena will be presented. Theoretical talks on how the top quark fits into the Standard Model and its potential extensions will also be presented. This workshop will complement the yearly Top Workshop which is held in September and will benefit from many new results expected to be presented at winter conferences in 2015...

  20. Regional differences in HIV prevalence among drug users in China: potential for future spread of HIV?

    2008-08-01

    Full Text Available Abstract Background Drug use and in particular injecting drug use has been at the forefront of the explosive spread of HIV in general populations in many countries in Asia. There is concern that also in China increased HIV incidence in drug users might spark off a generalized epidemic in the wider population. Close monitoring of HIV incidence and risk factors in drug users is therefore important to be able to target interventions effectively. Second generation surveillance was launched to assess HIV prevalence and risk behaviours jointly with the purpose of describing trends and predicting future developments. To assess whether these goals were fulfilled among drug users in China we provide an analysis of risk factors for HIV infection and of regional differences in HIV prevalence. Methods We analysed data collected in 2005 in 21 drug user second generation surveillance sentinel sites from 14 provinces in China. We used random effects logistic regression to test for risk factors for HIV infection and regional differences. Results The overall HIV-1 antibody prevalence was 5.4% (279/5128; 4.9% among injecting drug users (IDU not sharing needles and 3.7% among non-injecting drug users. We found substantial heterogeneity among the surveillance sites with prevalence rates ranging between 0% and 54%. HIV status was strongly affected by the regional prevalence of HIV. Risk behaviours were highly prevalent in regions where HIV prevalence is still low. The distribution of duration of drug use in different sites indicated different stages of the drug use epidemics. Conclusion ]Regional differences in HIV prevalence in China reflect different stages of the drug use and HIV epidemics rather than differences in risk behaviours. Therefore, outbreaks of HIV among drug users in regions where prevalence is still low can be expected in the future. However, methodological limitations of surveillance embedded into routine systems limit the usability of existing

  1. Tradeoff between User Experience and BCI Classification Accuracy with Frequency Modulated Steady-State Visual Evoked Potentials.

    Steady-state visual evoked potentials (SSVEPs) have been widely employed for the control of brain-computer interfaces (BCIs) because they are very robust, lead to high performance, and allow for a high number of commands. However, such flickering stimuli often also cause user discomfort and fatigue, especially when several light sources are used simultaneously. Different variations of SSVEP driving signals have been proposed to increase user comfort. Here, we investigate the suitability of frequency modulation of a high frequency carrier for SSVEP-BCIs. We compared BCI performance and user experience between frequency modulated (FM) and traditional sinusoidal (SIN) SSVEPs in an offline classification paradigm with four independently flickering light-emitting diodes which were overtly attended (fixated). While classification performance was slightly reduced with the FM stimuli, the user comfort was significantly increased. Comparing the SSVEPs for covert attention to the stimuli (without fixation) was not possible, as no reliable SSVEPs were evoked. Our results reveal that several, simultaneously flickering, light emitting diodes can be used to generate FM-SSVEPs with different frequencies and the resulting occipital electroencephalography (EEG) signals can be classified with high accuracy. While the performance we report could be further improved with adjusted stimuli and algorithms, we argue that the increased comfort is an important result and suggest the use of FM stimuli for future SSVEP-BCI applications.

    Full Text Available Demodex mites may be a potential etiological factor in the development of various eye and skin disorders. The aim of the study was to investigate the presence of Demodex in the hair follicles of eyelashes and their potential influence on abandoning soft contact lenses which had been previously well tolerated by their users. A group of 62 users of contact lenses (28 with emerging discomfort and 34 without discomfort were examined. There is a need to check the existence of a relationship between D. folliculorum or/and D. brevis infestation and the emergence of intolerance to the presence of soft contact lenses. The removed lashes were examined under light microscopy, applying standard parasitological methods if demodicosis is suspected. A positive result was assumed if at least one adult stage, larva, protonymph/nymph, or egg of D. folliculorum and/or D. brevis was present. A positive correlation was observed between the presence of Demodex and intolerance to contact lenses by their existing users p<0.05, and Demodex sp. infections were observed in 92.86% of patients with intolerance to contact lenses. Our results provide further evidence for the pathogenic role played by the mites in the development of eye diseases.

    Full Text Available Power wheelchairs (PWCs can have a positive impact on user well-being, self-esteem, pain, activity and participation. Newly developed intelligent power wheelchairs (IPWs, allowing autonomous or collaboratively-controlled navigation, could enhance mobility of individuals not able to use, or having difficulty using, standard PWCs. The objective of this study was to explore the perspectives of PWC users (PWUs and their caregivers regarding if and how IPWs could impact on current challenges faced by PWUs, as well as inform current development of IPWs. A qualitative exploratory study using individual interviews was conducted with PWUs (n = 12 and caregivers (n = 4. A semi-structured interview guide and video were used to facilitate informed discussion regarding IPWs. Thematic analysis revealed three main themes: (1 “challenging situations that may be overcome by an IPW” described how the IPW features of obstacle avoidance, path following, and target following could alleviate PWUs’ identified mobility difficulties; (2 “cautious optimism concerning IPW use revealed participants” addresses concerns regarding using an IPW as well as technological suggestions; (3 “defining the potential IPW user” revealed characteristics of PWUs that would benefit from IPW use. Findings indicate how IPW use may help overcome PWC difficulties and confirm the importance of user input in the ongoing development of IPWs.

    Full Text Available Reducing emissions from deforestation and forest degradation with other benefits (REDD+ mechanism is supposed to address the reversal of forest-based land degradation, conservation of existing carbon stocks, and enhancement of carbon sequestration. The Bosomtwe District is predominantly agrarian with potentials for climate change mitigation through REDD+ mechanism among smallholder farmers. The limited knowledge and practices of this strategy among farmers are limiting potentials of mitigating climate change. This paper assesses the REDD+ potentials among smallholder farmers in the district. Using a triangulation of quantitative and qualitative design, 152 farmer-respondents were purposively sampled and interviewed, using snowballing method from 12 communities. Quantitative data gathered were subjected to the tools of contingency and frequencies analysis, embedded in the Statistical Package for Social Sciences (SPSS v.16. The qualitative data were analyzed thematically. Results indicate that respondents have knowledge of REDD+ but not the intended benefit sharing regimes that can accrue to the smallholder farmers. Farmers’ willingness to practice REDD+ will be based on the motivation and incentive potentials of the strategies. The Forestry Services Division should promote the practice of REDD+ among smallholder farmers through education, to whip and sustain interest in the strategy.

    Full Text Available La Plata Basin is shared by five countries (Argentina, Bolivia, Brazil, Paraguay and Uruguay, which are having fast growing economies in South America. These countries need energy for their sustainable development; hence hydropower can play a very important role as a renewable clean source of energy. This paper presents an analysis of the current hydropower production and electricity demand in La Plata Basin (LPB and makes an analysis of the maximum and residual hydropower potential of the basin for a horizon of 30 yr (i.e. year 2040. Current hydropower production is estimated based on historic available data while future energy production is deduced from the maximum available water in the catchment, whereas electricity demand is assessed by correlating existing electricity demand with the estimated population growth and economic development. The maximum and residual hydropower potential of the basin, were assessed for the mean annual flows of the present hydrological regime (1970–2000 and topographical characteristics of the area.

    Computations were performed using an integrated GIS environment called Vapidro-Aste released by the Research on Energy System (Italy. The residual hydropower potential of the basin is computed considering that first the water supply needs for population, industry and agriculture are served and than hydropower energy is produced. The calculated hydropower production is found to be approximately half of the estimated electricity demand, which shows that there is a need to look for other sources of energy in the future.

    Full Text Available Heavy metals introduced into soil by indiscriminate dumping along with irrigating with sewage effluent often lead to toxic accumulation of heavy metal ions, which not only impair soil productivity but also cause health hazards by entering into food chain via soil-plant-animal-atmosphere continuum. To evaluate the potential of different crop species for nickel (Ni and cadmium (Cd phytoremediation, fifteen crop species comprising of cereals, vegetables and flowers were collected from differentially contaminated soils (DTPA-Cd 5.7-6.75 mg kg–1, DTPA-Ni 16.50- 20.85 mg kg–1. The tissue metal concentration and relative efficiency of transfer of heavy metals from soil to plant (transfer factor for various groups of crops were worked out. The uptake of Cd and Ni increased with contents in soils and the major part of taken up Cd and Ni is translocated to the floricultural crops with maximum accumulation occurred in roots. Values of translocation factor of Cd and Ni were ranged between 0.2 to 0.8 and 0.2 to 1.0 respectively for the different crops studied. The mean total root colonization by arbuscular mycorrhiza in these soils ranged from 15% for cauliflower to 76% for marigold, suggesting a certain adaptation of these indigenous to such environmental stress. Among the different crops studied marigold with highest translocation factor, mycorrhization and Cd and Ni content in root part holds considered as a potential economic crop for phytoremediation.

    Motor-evoked potential (MEP) monitoring was performed during 196 consecutive spinal (79 cervical and 117 lumbar) surgeries for the decompression of compressive spinal and spinal nerve diseases. MEP monitoring in spinal surgery has been considered sensitive to predict postoperative neurological recovery. In this series, transcranial stimulation consisted of trains of five pulses at a constant voltage (200-600 V). For the normalization of MEP, we recorded compound muscle action potentials (CMAP) after peripheral nerve stimulation, usually on the median nerve at the wrist 2 seconds before or after each transcranial stimulation of the motor area, for all operations. The sensitivity and specificity of MEP monitoring was 100% and 97.4%, respectively, or 96.9% with or without CMAP compensation (if the threshold of postoperative motor palsy was defined as 20% relative amplitude rate [RAR]). The mean RAR after CMAP normalization, of the most affected muscle in the patient group with excellent postoperative results (recovery rate of a Japan Orthopedic Association score of more than 50%) was significantly higher than that in the other groups (p=0.0224). All patients with an amplitude increase rate (AIR) with CMAP normalization of more than 20% achieved neurological recovery postoperatively. Our results suggest that if the RAR is more than 20%, postoperative motor palsy can be avoided in spinal surgery. If the AIR with normalization by CMAP after peripheral nerve stimulation is more than 20%, neurological recovery can be expected in spinal surgery.

    Caffeine is one of the most widely consumed stimulant drugs of the modern world. It brings about a feeling of well-being, relaxation, increased alertness and concentration. Its effects have been studied on brain function and behavior using mood questionnaires, reaction time tests, memory tests, EEG and of late Event Related Potentials (ERPs). This study evaluates the response of caffeine on ERPs and Reaction Time (RT) using auditory "oddball" paradigm. Forty undergraduate medical students volunteered for the study and their ERPs and RT were recorded before and after 40 minutes of ingestion of caffeine. There was a non-significant decrease in latency of N1, P2, N2 and P3 and a significant decrease in Reaction Time after caffeine consumption. The amplitude of P3 showed a significant increase after intake of caffeine. The results of this study indicate that caffeine leads to facilitation of information processing and motor output response of the brain.

    Family health history (FHx) is one of the most important risk factors for disease. Unfortunately, collection and use of FHx is under-utilized in the clinical setting. Efforts to improve collection of FHx have had minimal impact. A novel approach to collect FHx using social networking capabilities is being explored. We conducted a nationwide survey of 5,258 respondents to 1- assess the interest in using an online social network for FHx, 2- identify if such a tool would have clinical utility, and 3- identify notable trends and potential concerns. We found survey respondents to be very supportive of the proposed approach and interesting trends related to age, education, and race were identified. Results from this survey will be used to guide future research and development of a proposed FHx social network application. PMID:26958272

    Full Text Available With the popularity of smartphones, the problem of excessive use has drawn increasing attention. However, it is not clear whether there is an inhibitory deficit in excessive smartphone users. Using a modified Go/NoGo task with three types of context (blank, neutral and smartphone-related, the present study combined measures of behavior and electrophysiology (event-related potentials, ERPs to examine general and specific inhibitory control in an excessive smartphone use group and a normal use group. Results showed that participants in both groups had larger amplitude of N2 and P3 on NoGo trials than Go trials. NoGo N2, an ERP component associated with inhibitory control, was more negative in the excessive smartphone use group than the normal use group. These results suggest that in the early stage of inhibition processing, excessive smartphone users experience more conflicts and show a general deficit that does not depend on smartphone-related cues. Moreover, the study provides further neuroscience evidence of the physiological correlates of excessive smartphone use.

    Full Text Available In this article, we first discuss the inclusion of idioms in the latest printed editions of monolingual learner’s dictionaries; we then consider and evaluate the success of look-up operations in connection with the recognition of the correct part of speech. The central part of the article discusses and justifies the macro- and microstructural treatment of multi-word lexical items. Finally, we address the issue of including idioms in the microstructure as special senses of the lemma, as usage examples and/or in the idioms section. The inclusion and treatment of multi-word lexical items depends on the needs of potential dictionary users. Lexicographers should therefore strive to adopt a pragmatic approach that would help the user to locate a multi-word lexical item with minimal effort. When compiling a bilingual dictionary, contrastive differences between source and target languages should also be taken into consideration. http://dx.doi.org/10.5128/ERYa7.15

    subsequent success in sales. However some techniques, although beneficial to pharmaceutical promotion, need to be monitored by policymakers and regulatory advisors, as they have the potential to negatively impact consumer health knowledge. Overall, through this review it is evident that there are a number if techniques that employed by pharmaceutical marketers to augment the success of pharmaceutical promotion. While these techniques may be beneficial to pharmaceutical companies and might increase awareness amongst consumers, it is important to be critical of them, as they have the potential to be exploited by pharmaceutical marketers. This review indicated that although some techniques are successful and appear to be satisfactory in providing information to consumers, other techniques need to be appraised more closely.

    In spite of the clinical utility of buprenorphine, parenteral abuse of this medication has been reported in several laboratory investigations and in the real world. Studies have demonstrated lower abuse liability of the buprenorphine/naloxone combination relative to buprenorphine alone. However, clinical research has not yet examined the utility of the combined formulation to deter intranasal use in a buprenorphine-maintained population. Heroin-using volunteers (n = 12) lived in the hospital for 8-9 weeks and were maintained on each of three sublingual buprenorphine doses (2, 8, 24 mg). Under each maintenance dose, participants completed laboratory sessions during which the reinforcing and subjective effects of intranasal doses of buprenorphine (8, 16 mg), buprenorphine/naloxone (8/2, 8/8, 8/16, 16/4 mg) and controls (placebo, heroin 100 mg, naloxone 4 mg) were assessed. Intranasal buprenorphine alone typically produced increases in positive subjective effects and the 8 mg dose was self-administered above the level of placebo. The addition of naloxone dose dependently reduced positive subjective effects and increased aversive effects. No buprenorphine/naloxone combination dose was self-administered significantly more than placebo. These data suggest that within a buprenorphine-dependent population, intranasal buprenorphine/naloxone has reduced abuse potential in comparison to buprenorphine alone. These data strongly argue in favor of buprenorphine/naloxone rather than buprenorphine alone as the more reasonable option for managing the risk of buprenorphine misuse.

    To assist the Department of Energy, Office of Fuels Conversion (OFC), in implementing the synthetic fuel exemption under the Powerplant and Industrial Fuel Use Act (FUA) of 1978, Resource Consulting Group, Inc. (RCG), has developed a procedure for matching prospective users and producers of synthetic fuel. The matching procedure, which involves a hierarchical screening process, is designed to assist OFC in: locating a supplier for a firm that wishes to obtain a synthetic fuel exemption; determining whether the fuel supplier proposed by a petitioner is technically and economically capable of meeting the petitioner's needs; and assisting the Synthetic Fuels Corporation or a synthetic fuel supplier in evaluating potential markets for synthetic fuel production. A data base is provided in this appendix on proposed and ongoing synthetic fuel production projects to be used in applying the screening procedure. The data base encompasses a total of 212 projects in the seven production technologies.

    Full Text Available Twenty years ago, Kaposi’s sarcoma (KS was the oncologic counterpart to Winston Churchill’s Russia: a riddle, wrapped in a mystery, inside an enigma. First described by Moritz Kaposi in 1872, who reported it to be an aggressive skin tumor, KS became known over the next century as a slow-growing tumor of elderly men—in fact, most KS patients were expected to die with the tumor rather than from it. Nevertheless, the course and manifestations of the disease varied widely in different clinical contexts. The puzzle of KS came to the forefront as a harbinger of the AIDS epidemic. The articles in this issue of Viruses recount progress made in understanding Kaposi’s sarcoma herpesvirus (KSHV since its initial description in 1994.

    This paper will inform mental health service users and carers on how a University in Wales established a service user and carer-led research group. * The group's primary aim will be to undertake its own service user and carer-led research projects. * Mental health service users have undergone empowerment and research training at a University in Wales. This is an important initiative because it is the first service user and carer-led research group in Wales. * This paper is co-authored by a mental health service user and includes transcripts of service users' stories written in their words. Abstract Service user and carer involvement in research has been gaining momentum in recent years. However, this involvement to date has primarily been as research respondents or 'subjects' in research studies. A group of mental health service users at a University in Wales underwent empowerment and research training to enable them to become active participants in the research process; this training was a necessary step to equip mental health service users with the skills to become independent researchers and to carry out service user-led research. We included transcripts from mental health service users on their views of the empowerment and research training received. We are not reporting, in this paper, on the findings from a research study rather it aims to inform readers how a service user and carer-led research group has been established in Wales. The group has two purposes: (1) to train service users in research methodologies, and thus for them to gain essential research skills; and (2) to undertake their own service user and carer-led research projects thereby implementing the research skills they have acquired from the training. The latter is a primary aim of the group; a future paper will report on its development.

    Community health workers are reemerging as an essential component of health systems in low-income countries. However, there are concerns that unless they are adequately supported, their motivation and performance will be suboptimal. mHealth presents an opportunity to improve support for community health workers; however, most interventions to date have been designed through a top-down approach, rarely involve the end user, and have not focused on motivation. To use formative research to explore the views of community health workers in Uganda and Mozambique on the potential role of mHealth in their work delivering integrated community case management of children. We conducted 24 in-depth interviews and 5 focus group discussions with community health workers in Uganda and Mozambique. Data were collected on: current phone use, preferred phone and charger characteristics, and perceptions of a range of potential mHealth interventions. Interviews were conducted in the local language, were audio recorded and converted into expanded notes. Interviews were coded for key thematic areas using both deductive and inductive codes. Deductive codes included mHealth's potential impact on motivation and performance. The most salient roles of mHealth in improving performance and motivation were reducing the need for travel, improving efficiency and planning, receiving feedback and information, and improving communication with supervisors and other community health workers. This was mostly through improved voice and short message service (SMS) text communication. Specific components of mHealth interventions that participants felt could improve motivation included increasing their visibility and credibility through branding of phones; providing an SMS response to data submission; and sending SMS messages about the importance of their work and achievements, rather than just reminders or technical messages. Participants identified feasibility issues related to the language of SMS

  4. Potential Safety Benefit of the Blind Spot Detection System for Large Trucks on the Vulnerable Road Users in Taiwan

    Full Text Available Considering motorcyclists, pedestrians and bicyclists as vulnerable road users (VRUs, more than 75 percent of the victims of fatal crashes involving large trucks in Taiwan are VRUs. Most crashes occurred at or were due to the blind spots of large trucks because of the size and traveling locations of the VRUs. This study applies typology and statistical methods to estimate the potential safety benefit of blind spot detection (BSD systems for large trucks on VRUs. The pre-crash scenarios associated with the blind spots of large trucks were derived by counting the maneuvers of large trucks and VRUs, prior to crashes, the truck drivers’ improper behaviors (cause of crashes, and the crash types. The number of crashes and fatalities were counted for the pre-crash scenario relevant to the BSD systems. A value of 0.8 of human machine interface factor (HMIF based on a previous study was applied to estimate the potential safety benefits of the BSD system. The results show that the implementation of BSD systems on all large trucks could help avoid about 24, 10, and 11 percent of large truck-involved crashes with pedestrians, bicycles, and motorcycles, respectively. The BSD systems could also save 5 pedestrians, 3 bicyclists, and 15 motorcyclists per year from crashes involving large trucks.

    Litter washed ashore on the coastline, also called beach litter, constitutes one of the most obvious signs of marine litter pollution. Surveys of beach litter represent a fundamental tool for monitoring pollution in the marine environment and have been used world-wide to classify and quantify marine litter. Identifying the sources of marine and beach litter is, together with education, the prime weapon in combating this type of pollution. This work investigates the impact of three main potential land sources on litter occurrence: urban areas, rivers and beach users. Three sources were analyzed simultaneously on a broad scale (Lazio region, central Italy) using a random sampling design and fitting a generalized linear mixed-effect model. The results show that urban areas are the main drivers for the occurrence of marine litter along central Italy's coastal ecosystems, suggesting that the presence of such litter on Lazio beaches could be effectively reduced by identifying failings in recycling and waste collection procedures and by improving waste processing systems and sewage treatment in urban areas.

    With the increased international focus on personalized health care and preventive medicine, next-generation sequencing (NGS) has substantially expanded the options for carrier screening of serious, recessively inherited diseases. NGS screening tests not only offer reproductive options not previously available to couples, but they may also ultimately reduce the number of children born with devastating disorders. To date, preconception carrier screening (PCS) has largely targeted single diseases such as cystic fibrosis, but NGS allows the testing of many genes or diseases simultaneously. We have developed an expanded NGS PCS test for couples; simultaneously it covers 50 very serious, early-onset, autosomal recessive diseases that are untreatable. This is the first, noncommercial, population-based, expanded PCS test to be offered prospectively to couples in a health-care setting in Europe. So far, little is known about how potential users view such a PCS test. We therefore performed an online survey in 2014 among 500 people from the target population in the Netherlands. We enquired about their intention to take an expanded PCS test if one was offered, and through which provider they would like to see it offered. One-third of the respondents said they would take such a test were it to be offered. The majority (44%) preferred the test to be offered via their general practitioner (GP) and 58% would be willing to pay for the test, with a median cost of €75. Our next step is to perform an implementation study in which this PCS test will be provided via selected GPs in the Northern Netherlands. PMID:27165008

    This paper examines the addictive potential of 8 different Internet applications, distinguishing male and female users. Moreover, differential correlates of problematic use are investigated in Internet gamers (IG) and generalized Internet users (GIU). In a representative sample of 5,667 adolescents aged 12-19 years, use of Internet applications, problematic Internet use, psychopathologic symptoms (emotional problems, hyperactivity/inattention, and psychosomatic complaints), personality (conscientiousness and extraversion), psychosocial correlates (perceived stress and self-efficacy), and coping strategies were assessed. The addictive potential of Internet applications was examined in boys and girls using regression analysis. MANOVAs were conducted to examine differential correlates of problematic Internet use between IG and GIU. Chatting and social networking most strongly predicted problematic Internet use in girls, while gaming was the strongest predictor in boys. Problematic IG exhibited multiple psychosocial problems compared to non-problematic IG. In problematic Internet users, GIU reported even higher psychosocial burden and displayed dysfunctional coping strategies more frequently than gamers. The results extend previous findings on the addictive potential of Internet applications and validate the proposed distinction between specific and generalized problematic Internet use. In addition to Internet gaming disorder, future studies should also focus on other highly addictive Internet applications, that is, chatting or social networking, regarding differential correlates of problematic use. © 2017 S.

    Full Text Available Since achieving statehood in 1991, Armenia has faced major economic and political obstacles which have significantly affected the nation’s research libraries. This research paper will quantitatively and qualitatively examine the challenges facing Armenian research libraries just over twenty years after the collapse of the Soviet Union. Specifically, the authors analyze their interviews with five library administrators at five major institutions, respectively. These include Yerevan State University Library, the National Library of Armenia, the Fundamental Scientific Library of the National Academy of Sciences of Armenia, the Republican Scientific-Medical Library of Armenia, and the Papazian Library of the American University of Armenia. The instrument for the interviews consists of 73 questions based on the 2004 Association of College and Research Libraries Standards for Libraries in Higher Education and evaluates the following factors:• The library’s mission, goals and objectives• Public or user services• Instruction activities at the library• Resources (print, media, or electronic and collection development• Access to the library’s resources• Outcome assessment, or evaluation of the library• Staffing issues• Facility maintenance and plans for library development• Communication and cooperation both within the library and with the user community• Administration• BudgetIn addition, we will focus on the strengths and weaknesses of these libraries and investigate the growing open access movement in Armenia. Based on our findings, the authors wish to facilitate dialogue and consider possible approaches to help these libraries meet Armenia’s pressing information needs.

    Lorcaserin is a selective and potent serotonin 2C receptor subtype (5-HT(2C)) agonist under development for the treatment of obesity. This study assessed the drug's abuse potential on the basis of its pharmacological profile. For this purpose, a double-blind, double-dummy, placebo-controlled, randomized seven-way crossover study with single oral doses of lorcaserin (20, 40, and 60 mg), zolpidem (15 and 30 mg), ketamine (100 mg), and placebo was conducted in recreational polydrug users (N = 35). Subjective and objective measures were assessed up to 24 h after the dose. We found that zolpidem and ketamine had significantly higher peak scores relative to placebo on the primary measures as well as on most of the secondary measures. The subjective effects of a 20-mg dose of lorcaserin were similar to those of placebo, whereas supratherapeutic doses of lorcaserin were associated with significant levels of dislike by users as compared with placebo, zolpidem, and ketamine. Perceptual effects were minimal after administration of lorcaserin and significantly lower than after administration of either ketamine or zolpidem. The findings suggest that, at supratherapeutic doses, lorcaserin is associated with distinct, primarily negative, subjective effects and has low abuse potential.

    Although visual implant prosthesis projects are advancing, little exists in the literature on the factors that would lead an individual to volunteer for such an experimental procedure. Many ethical issues are raised in recruiting and involving individuals in experimental implant procedures, most involving autonomy and informed consent. This report provides perspectives of 30 totally or legally blind older individuals on their expectations about a potential visual implant, their motivations for volunteering, and the processes they would use for decision making. Data were collected in eight focus groups, using semistructured focus group processes. Among the primary reasons a person with seriously impaired vision would volunteer for a new implant procedure are helping others, exploring the unknown, and restoring perception. The decision to participate in an experimental brain implant procedure is complex. Potential recipients have many questions about the device and the procedure, the perceived risks, and the commitment of a research team to the participants once a device has been implanted. Some would involve their family in a decision; others are more comfortable making the decision independent, after consulting others. The themes identified provide a guide for recruiting and ensuring an ethical experience for participants in experimental protocols.

    In order to evaluate the potential for coal utilization, a preliminary technical and economic assessment of district coal gasification in New Jersey was conducted. This evaluation addressed the possibility of installing a coal gasification plant to use a high sulfur eastern coal to produce a medium Btu content gas (MBG) having a heating value of approximately 300 Btu/SCF. In addition, the work also appraised the regulatory, environmental and marketing, and financial considerations of such a facility. The preliminary study evaluation has manifested an overall technical and economic feasibility for producing a medium Btu quality gas (MBG) from coal at PSE and G's Sewaren Generating Station in New Jersey. The production of MBG for use in on-site power plant boilers or for distribution to industrial customers appears to be economically attractive. The economic attractiveness of MBG is very dependent on the location of sufficient numbers of industrial customers near the gasification facilities and on high utilization of the gasification plant. The Sewaren Generating Station was identified as potentially the most suitable site for a gasification plant. The Texaco Coal Gasification Process was selected as the gasifier type due to a combination of efficiency and pilot plant experience. It is projected that a nominal 2000 tons-per-day coal gasification plant would supply supplemental utility boiler fuel, fuel grade methanol and some by-products.

    "Excessive" viewing of visual sexual stimuli (VSS) is the most commonly reported hypersexual behavior problem and is especially amenable to laboratory study. A pattern of enhanced sexual cue responsiveness is expected in this sample if hypersexuality shares features of other addiction models. Participants (N=122) who either reported or denied problematic VSS use were presented with emotional, including explicit sexual, images while their evoked response potentials were recorded. An interaction of hypersexual problem group and the level of desire for sex with a partner predicted LPP amplitude. Specifically, those reporting problems regulating their VSS use who also reported higher sexual desire had lower LPP in response to VSS. This pattern appears different from substance addiction models. These are the first functional physiological data of persons reporting VSS regulation problems.

    In the twentieth century, vaccination has been possibly the greatest revolution in health. Together with hygiene and antibiotics, vaccination led to the elimination of many childhood infectious diseases and contributed to the increase in disability-free life expectancy that in Western societies rose from 50 to 78–85 years (Crimmins, E. M. & Finch, C. E. 2006 Proc. Natl Acad. Sci. USA 103, 498–503; Kirkwood, T. B. 2008 Nat. Med 10, 1177–1185). In the twenty-first century, vaccination will be expected to eliminate the remaining childhood infectious diseases, such as meningococcal meningitis, respiratory syncytial virus, group A streptococcus, and will address the health challenges of this century such as those associated with ageing, antibiotic resistance, emerging infectious diseases and poverty. However, for this to happen, we need to increase the public trust in vaccination so that vaccines can be perceived as the best insurance against most diseases across all ages. PMID:21893537

    Novel solutions to conserve biodiversity whilst allowing for resource harvesting are urgently needed. In marine systems, Territorial User Rights for Fisheries (TURFs) are promoted to enable sustainable use of resources. We investigate the potential for synergies between nature-based tourism and TURFs on Chile's central coast. Of 135 recreational divers surveyed, 77% indicated that the fish species they preferred sighting were declining and 80% indicated that they would dive more often in TURFs, which have higher abundance of favoured species. Regression analysis shows that respondents that perceive that TURFs fulfil a conservation function are more willing to pay to dive in a TURF. However, respondents who understand the bureaucratic functioning of a TURF are less willing to pay, and there is diversity in how divers feel payments should be made. A participatory approach is required to navigate these complexities to achieve synergies between nature-based tourism and resource harvesting in TURFs.

    Full Text Available Background: New permanent contraceptive methods are in development, including nonsurgical permanent contraception (NSPC. Objective: In the present study, perceptions of NSPC in India among married women, married men, mothers-in-law, providers, and health advocates in Eastern Maharashtra (Wardha district and New Delhi were examined. Methods: We conducted semi-structured interviews with 40 married women and 20 mothers-in-law; surveys with 150 married men; and focus group discussions with obstetrics/gynecology providers and advocates. Transcripts were coded and analyzed using a grounded theory approach, where emerging themes are analyzed during the data collection period. Results: The majority of female respondents expressed support of permanent contraception and interest in NSPC, stating the importance of avoiding surgery and minimizing recovery time. They expressed concerns about safety and efficacy; many felt that a confirmation test would be necessary regardless of the failure rate. Most male respondents were supportive of female permanent contraception (PC and preferred NSPC to a surgical method, as long as it was safe and effective. Providers were interested in NSPC yet had specific concerns about safety, efficacy, cost, uptake, and government pressure. They also had concerns that a nonsurgical approach could undermine the inherent seriousness of choosing PC. Advocates were interested in NSPC but had concerns about safety and potential misuse in the Indian context. Conclusion: Although perceptions of NSPC were varied, all study populations indicated interest in NSPC. Concerns about safety, efficacy, appropriate patient counseling, and ethics emerged from the present study and should be considered as NSPC methods continue to be developed.

    Objective. To compare the oral abuse potential of hydrocodone extended-release (ER) tablet developed with CIMA® Abuse-Deterrence Technology with that of hydrocodone immediate release (IR). Design. Randomized, double-blind, placebo-controlled, crossover study. Setting and Patients. One study site in the United States; adult nondependent, recreational opioid users. Methods. After confirming their ability to tolerate and discriminate hydrocodone IR 45 mg from placebo, eligible participants were randomized to receive each of the following oral treatments once: finely crushed placebo, hydrocodone IR 45-mg powder, intact hydrocodone ER 45-mg tablet, and finely crushed hydrocodone ER 45-mg tablet. Primary pharmacodynamic measure was “at the moment” drug liking. Secondary measures included overall drug liking, drug effects (e.g., balance, positive, negative, sedative), pupillometry, pharmacokinetics, and safety. Results. Mean maximum effect (Emax) for “at the moment” drug liking was significantly lower for intact (53.9) and finely crushed hydrocodone ER (66.9) vs. hydrocodone IR (85.2; P < 0.001). Drug liking for intact hydrocodone ER was comparable to placebo (Emax: 53.9 vs. 53.2). Secondary measures were consistent with these results, indicating that positive, negative, and sedative drug effects were diminished with intact and crushed hydrocodone ER tablet vs. hydrocodone IR. The 72-hour plasma concentration-time profile for each treatment mimicked its respective “at the moment” drug-liking-over-time profile. Incidence of adverse events was lower with intact hydrocodone ER (53%) vs. hydrocodone IR (79%) and finely crushed hydrocodone ER (73%). Conclusions. The oral abuse potential of hydrocodone ER (intact and finely crushed) was significantly lower than hydrocodone IR in healthy, nondependent, recreational opioid users. Hydrocodone ER was generally well tolerated. PMID:27330154

    2012-01-01

    User Design offers a fresh perspective on how front-line learners (users) can participate in the design of learning environments. The author challenges the universal assumption that front-line users must be relegated to the role of offering input, and that the actual design activity of learning systems must still be conducted only by experts. The book presents a new set of methods and strategies that show how the tools of professional designers can be effectively shared with broad groups of users and other participants in the process of creating their own learning. Drawing

    Dolog, Peter; Kay, Judy; Kummerfeld, Bob

    This paper explores an architecture for very long term user modelling, based upon personal user model clouds. These ensure that the individual's applications can access their model whenever it is needed. At the same time, the user can control the use of their user model. So, they can ensure...... it is accessed only when and where they wish, by applications that they wish. We consider the challenges of representing user models so that they can be reused by multiple applications. We indicate potential synergies between distributed and centralised user modelling architectures, proposing an architecture...

    This document describes the PANTHER R&D Application, a proof-of-concept user interface application developed under the PANTHER Grand Challenge LDRD. The purpose of the application is to explore interaction models for graph analytics, drive algorithmic improvements from an end-user point of view, and support demonstration of PANTHER technologies to potential customers. The R&D Application implements a graph-centric interaction model that exposes analysts to the algorithms contained within the GeoGraphy graph analytics library. Users define geospatial-temporal semantic graph queries by constructing search templates based on nodes, edges, and the constraints among them. Users then analyze the results of the queries using both geo-spatial and temporal visualizations. Development of this application has made user experience an explicit driver for project and algorithmic level decisions that will affect how analysts one day make use of PANTHER technologies.

    2017-08-01

    Systematic reviews of quantitative evidence are well established in health and social care. Systematic reviews of qualitative evidence are increasingly available, but volume, topics covered, methods used, and reporting quality are largely unknown. We provide a descriptive overview of systematic reviews of qualitative evidence assessing health and social care interventions included on the Database of Abstracts of Reviews of Effects (DARE). We searched DARE for reviews published between January 1, 2009, and December 31, 2014. We extracted data on review content and methods, summarized narratively, and explored patterns over time. We identified 145 systematic reviews conducted worldwide (64 in the UK). Interventions varied but largely covered treatment or service delivery in community and hospital settings. There were no discernible patterns over time. Critical appraisal of primary studies was conducted routinely. Most reviews were poorly reported. Potential exists to use systematic reviews of qualitative evidence when driving forward user-centered health and social care. We identify where more research is needed and propose ways to improve review methodology and reporting. Copyright © 2017 Elsevier Inc. All rights reserved.

  13. Which Russia, twenty years later?

    2011-12-01

    Full Text Available Russia is proud of its position among the emerging powers, of the strength provided by its ample energetic resources and its nuclear potential with which it can influence the world and always be taken into account. Nevertheless, the perception within the country is that stagnation has become Russia’s dominant characteristic at present. The objective of this article is to explore how this situation came about, analysing the evolution of domestic processes in Russia during both of its most defining periods: Yeltsin and Putin’s leadership, since the ephemeral presidency of Medvedev proved to be basically a continuation of the latter. During the eight years of Boris Yeltsin’s tenure, the state of crisis, latent or open, developed into the way that political processes are carried out in Russia. With Putin’s arrival, however, stability and State control are imposed, against the backdrop of economic growth, and they become values in themselves, far from the democratic discourse of the first years.

    2009-12-15

    The municipal, regional and national authorities wanted to assess the potential of electric-assisted bicycles in the Geneva region. A survey performed by the University of Geneva is reported. The following points were investigated: (i) Who uses an electric bicycle? (ii) How is an electric bicycle used? (iii) Why is an electric bicycle purchased? (iv) How many people could potentially use an electric bicycle in the Geneva region? (v) How much energy would be saved and what fraction of the carbon dioxide emissions would be avoided thanks to electric bicycles in the region? Some interesting results: Most current electric bicycle users are women and live in Geneva outskirts. Most users have an academic degree or equivalent and have a good job. Most of them have also a car and other bicycles without electric motor. The main uses of electric bicycles is commuting between house and job locations, leisure activities and shopping. The average annual distance per electric bicycle is about 3000 km. The majority of the electric bicycles in use are limited to 25 km/h and can be driven without any license. The users wish an extension of the bicycle track network along the roads and of the protected parking areas. The number of potential users in the City of Geneva is estimated to 9% or 15,600 new users and to 10% or 43,000 new users in the suburbs. In 2030, 7,500,000 litres-equivalent of gasoline could be annually saved in the region and more than 16,000 tons CO{sub 2} emissions avoided.

  19. The Potential for the Development of the X-ray Free Electron Laser Multi-User Photon Distribution System for XFEL Laboratory

    CERN Document Server

    Saldin, Evgeny L; Yurkov, Mikhail V

    2004-01-01

    X-ray photon beam from a SASE FEL undulator is in principle a single user tool, just like an optical laser. Therefore, the operation and amortization cost cannot be easily spread over many simultaneous experiments. To avoid prohibitive cost for each experiment, a new XFEL laboratory scheme is proposed. A photon beam distribution system based on movable multilayer X-ray mirrors can provide an efficient way to generate a multi-user facility. Distribution of photons is achieved on the basis of pulse trains and it is possible to partition the photon beam among a few tens independent beamlines thereby obtaining many users working in parallel. The second way to increase the number of simultaneous experiments is based on the working with a series of perfect crystals in transmission (Laue) geometry. The later concept is the basic idea of the Troika beamline at ESRF. In principle, a hundred of photon beamlines with different experiments can be served by a single XFEL source.

  7. Twenty-first century learning in afterschool.

    Schwarz, Eric; Stolow, David

    2006-01-01

    Twenty-first century skills increasingly represent the ticket to the middle class. Yet, the authors argue, in-school learning is simply not enough to help students develop these skills. The authors make the case that after-school (or out-of-school) learning programs are emerging as one of the nation's most promising strategies for preparing young people for the workforce and civic life. Most school systems have significant limitations for teaching twenty-first century skills. They have the limits of time: with only six hours per day there is barely enough time to teach even the basic skills, especially for those students starting already behind. They have the limits of structure: typical school buildings and classrooms are not physically set up for innovative learning. They have the limits of inertia and bureaucracy: school systems are notoriously resistant to change. And perhaps most important, they have the limits of priorities: especially with the onset of the No Child Left Behind Act, schools are laserlike in their focus on teaching the basics and therefore have less incentive to incorporate twenty-first century skills. Meanwhile, the authors argue that after-school programs are an untapped resource with three competitive advantages. First, they enable students to work collaboratively in small groups, a setup on which the modern economy will increasingly rely. Second, they are well suited to project-based learning and the development of mastery. Third, they allow students to learn in the real-world contexts that make sense. Yet the after-school sector is fraught with challenges. It lacks focus-Is it child care, public safety, homework tutoring? And it lacks rigorous results. The authors argue that the teaching of twenty-first century skills should become the new organizing principle for afterschool that will propel the field forward and more effectively bridge in-school and out-of-school learning.

    2009-01-01

    Evaluation on Internet portals is a key component of any online resource development. Understanding user information seeking behaviour and user perceived behaviour is essential to obtain the full picture of user needs, online activities and draw lessons to improve the design of Internet portals to better meet user expectations. This article discusses the evaluation of a WHO Internet portal: the Labresources website. The evaluation investigates user satisfaction with the resource, usability, demographic information about users and how well they could complete specific tasks using the website and compared this with the actual online behaviour revealing a number of discrepancies. An online questionnaire was advertised on the Labresources website during the period 25 November 2005 to 20 February 2006. As the site caters to English and French speakers, the questionnaire was made available in both languages. It consisted of two sections - the first section required the participant to complete three tasks using the website whereas the second section tested user satisfaction, information needs and appropriateness of the content. Weblogs data were compared with the questionnaire results to compare user perceived and actual online behaviour. Twenty one respondents completed the online questionnaire from a total of 18 countries. This was out of a potential 60 website users among whom the questionnaire was promoted. In general, respondents were satisfied with the website layout and navigation. 61.9% of respondents listed WHO among their top 5 and a third listed the Labresources website. The number of sessions where users browse (146) the information resources is almost three times more than the number of users who search (52) the resources. Weblogs revealed most interesting results with differences between what users reported doing when completing tasks and how easy they perceived the tasks and what they actually did. Twelve respondents completed at least one task. Of the

Analysis results are presented which indicate that one servicing bay will be sufficient to accommodate IOC customer servicing requirements. Growth servicing requirements indicate that an additional servicing bay will be needed for accommodation of the far-term SATS mission payloads. Even though the level of total mission accommodation is below 100 percent for one bay at IOC and two bays during growth operations, the levels are such that operational work-around exists so that additional servicing bays will not be required.

  14. A Study of Application Layer Paradigm for Lower Layer Energy Saving Potentials in Cloud-Edge Social User Wireless Image Sharing

    Directory of Open Access Journals (Sweden)

    2015-08-01

    Full Text Available Energy saving becomes critical in modern cloud wireless multimedia and mobile communication systems. In this paper we propose to study a new paradigm named application layer Position-Value diversity for wireless image sharing for cloud-edge communications, which has significant energy saving potentials for modern wireless networking systems. In this new paradigm, saving energy is achieved by looking into application layer imaging traffic, in stead of MAC-PHY protocols at lower layers, and partitioning it into important positions and unimportant values. This paradigm could be integrated to existing wavelet-based tree compression, and truncation of image bit streams could be performed with regards to wireless communication energy budget estimation. Simulation results demonstrated that there are significant potentials of communication energy efficiency gain and Quality of Experience (QoE enhancement in wireless image communication systems.

    2013-01-01

    Full Text Available Context: With an increase in the abuse of various oral habitual products in India over the past few decades; the incidence of oral potentially malignant conditions as leukoplakia, oral submucous fibrosis and squamous cell carcinoma (SCC rates have also increased. No recent study has been conducted reporting the scenario of oral cancer and potentially malignant conditions in Eastern India (specifically Kolkata. Aims: The present study was conducted at Dr. R. Ahmed Dental College, Kolkata during 2010-2011 to find a possible correlation between the effects of the different oral habits, age, sex and the different types of oral mucosal lesions among patients reported to the hospital. This study also enabled us to see the predilection of the various histopathological stages of the lesions for different sites of the oral cavity. Subjects and Methods: The study group consisted of 698 patients having either oral potentially malignant or malignant lesion. The control group consisted of 948 patients who had reported to the hospital for different oral/dental problems and had the habit of tobacco, areca nut and/or alcohol usage for at least 1 year. Statistical Analysis : The unadjusted odds ratio, the 95% confidence interval, and the P value were calculated to correlate patients with/without different kinds of habit and having/not having various kinds of oral lesions. Results: Our study shows that for males having the habit of taking smokeless tobacco or mixed habit poses the highest risk for developing SCC. For females, significant risk of developing SCC was found in patients habituated to processed areca nut chewing. Conclusion: This study presents probably for the first time in recent years the occurrence of oral potentially malignant and malignant conditions amongst patients having deleterious habits in a hospital based population of Kolkata.

    The adoption of technology in healthcare over the last twenty years has steadily increased, particularly as it relates to medical robotics and Multi-User Virtual Environments (MUVEs) such as Second Life. Both disciplines have been shown to improve the quality of care and have evolved, for the most part, in isolation from each other. In this paper, we present four synergies between medical robotics and MUVEs that have the potential to decrease resource utilization and improve the quality of healthcare delivery. We conclude with some foreseeable barriers and future research directions for researchers in these fields.

    Remote asynchronous usability testing is characterized by both a spatial and temporal separation of users and evaluators. This has the potential both to reduce practical problems with securing user attendance and to allow direct involvement of users in usability testing. In this paper, we report...... from an empirical study where we systematically compared three methods for remote asynchronous usability testing: user-reported critical incidents, forum-based online reporting and discussion, and diary-based longitudinal user reporting. In addition, conventional laboratory-based think-aloud testing....... This makes remote asynchronous methods an appealing possibility for usability testing in many software projects....

    Full Text Available We present the analysis of twenty human genomes to evaluate the prospects for identifying rare functional variants that contribute to a phenotype of interest. We sequenced at high coverage ten "case" genomes from individuals with severe hemophilia A and ten "control" genomes. We summarize the number of genetic variants emerging from a study of this magnitude, and provide a proof of concept for the identification of rare and highly-penetrant functional variants by confirming that the cause of hemophilia A is easily recognizable in this data set. We also show that the number of novel single nucleotide variants (SNVs discovered per genome seems to stabilize at about 144,000 new variants per genome, after the first 15 individuals have been sequenced. Finally, we find that, on average, each genome carries 165 homozygous protein-truncating or stop loss variants in genes representing a diverse set of pathways.

    Multi-model ensembles (MMEs) are powerful tools in dynamical climate prediction as they account for the overconfidence and the uncertainties related to single-model ensembles. Previous works suggested that the potential benefit that can be expected by using a MME amplifies with the increase of the independence of the contributing Seasonal Prediction Systems. In this work we combine the two MME Seasonal Prediction Systems (SPSs) independently developed by the European (ENSEMBLES) and by the Asian-Pacific (APCC/CliPAS) communities. To this aim, all the possible multi-model combinations obtained by putting together the 5 models from ENSEMBLES and the 11 models from APCC/CliPAS have been evaluated. The grand ENSEMBLES-APCC/CliPAS MME enhances significantly the skill in predicting 2m temperature and precipitation compared to previous estimates from the contributing MMEs. Our results show that, in general, the better combinations of SPSs are obtained by mixing ENSEMBLES and APCC/CliPAS models and that only a limited number of SPSs is required to obtain the maximum performance. The number and selection of models that perform better is usually different depending on the region/phenomenon under consideration so that all models are useful in some cases. It is shown that the incremental performance contribution tends to be higher when adding one model from ENSEMBLES to APCC/CliPAS MMEs and vice versa, confirming that the benefit of using MMEs amplifies with the increase of the independence the contributing models. To verify the above results for a real world application, the Grand ENSEMBLES-APCC/CliPAS MME is used to predict retrospective energy demand over Italy as provided by TERNA (Italian Transmission System Operator) for the period 1990-2007. The results demonstrate the useful application of MME seasonal predictions for energy demand forecasting over Italy. It is shown a significant enhancement of the potential economic value of forecasting energy demand when using the

    information. The study was complemented with an artefactual experimental game performed with 176 smallholders to identify and describe their risk preferences. The existing economic literature shows that farmers' risk preferences generally play a decisive role for agricultural decision-making indicating the importance of understanding farmer's risk profile when evaluating the potential use of climate information at the individual level. First results indicate that smallholders in the region are regularly exposed to extreme weather events such as frost, hailstorms and droughts. Under these conditions, farmers often do not have the capacity and sufficient resources to prevent periods of food insecurity at the end of the growing period. Hereby climate information can support the agricultural production decisions and improve food security but only if developed in close collaboration with the end-users.

    This final entry in the History of Human Space Exploration mini-series by Ben Evans continues with an in-depth look at the latter part of the 20th century and the start of the new millennium. Picking up where Partnership in Space left off, the story commemorating the evolution of manned space exploration unfolds in further detail. More than fifty years after Yuri Gagarin’s pioneering journey into space, Evans extends his overview of how that momentous voyage continued through the decades which followed. The Twenty-first Century in Space, the sixth book in the series, explores how the fledgling partnership between the United States and Russia in the 1990s gradually bore fruit and laid the groundwork for today’s International Space Station. The narrative follows the convergence of the Shuttle and Mir programs, together with standalone missions, including servicing the Hubble Space Telescope, many of whose technical and human lessons enabled the first efforts to build the ISS in orbit. The book also looks to...

    This groundbreaking text examines the problem of user authentication from a completely new viewpoint. Rather than describing the requirements, technologies and implementation issues of designing point-of-entry authentication, the book introduces and investigates the technological requirements of implementing transparent user authentication -- where authentication credentials are captured during a user's normal interaction with a system. This approach would transform user authentication from a binary point-of-entry decision to a continuous identity confidence measure. Topics and features: discu

    2017-03-01

    This systematic review aimed to synthesize qualitative evidence relating to user and service provider perspective on the acceptability and relative benefits and potential harms of art therapy for people with non-psychotic mental disorders. A comprehensive literature search was conducted in 13 major bibliographic databases from May to July 2013. A qualitative evidence synthesis was conducted using thematic framework synthesis. The searches identified 10,270 citations from which 12 studies were included. Ten studies included data from 183 service users, and two studies included data from 16 service providers. The evidence demonstrated that art therapy was an acceptable treatment. The benefits associated with art therapy included the following: the development of relationships with the therapist and other group members; understanding the self/own illness/the future; gaining perspective; distraction; personal achievement; expression; relaxation; and empowerment. Small numbers of patients reported varying reasons for not wanting to take part, and some highlighted potentially negative effects of art therapy which included the evoking of feelings which could not be resolved. The findings suggest that for the majority of respondents art therapy was an acceptable intervention, although this was not the case for all respondents. Therefore, attention should be focussed on both identifying those who are most likely to benefit from art therapy and ensuring any potential harms are minimized. The findings provide evidence to commissioners and providers of mental health services about the value of future art therapy services. Art therapy was reported to be an acceptable treatment for the majority of respondents. Art therapy may not be a preferred treatment option for a small number of patients, emphasizing the importance of considering patient preference in choice of treatment, and selection of the most suitable patients for art therapy. Consideration should be made of adjustments

    High performance computing at the Numerical Aerospace Simulation Facility at NASA Ames Research Center includes C90's, J90's and Origin 2000's. Not only is it necessary to protect these systems from outside attacks, but also to provide a safe working environment on the systems. With the right tools, security anomalies in the user s work environment can be deleted and corrected. Validating proper ownership of files against user s permissions, will reduce the risk of inadvertent data compromise. The detection of extraneous directories and files hidden amongst user home directories is important for identifying potential compromises. The first runs of these utilities detected over 350,000 files with problems. With periodic scans, automated correction of problems takes only minutes. Tools for detecting these types of problems as well as their development techniques will be discussed with emphasis on consistency, portability and efficiency for both UNICOS and IRIX.

  19. Twenty Seven Years of Quantum Cryptography!

    Science.gov (United States)

    Hughes, Richard

    2011-03-01

    One of the fundamental goals of cryptographic research is to minimize the assumptions underlying the protocols that enable secure communications between pairs or groups of users. In 1984, building on earlier research by Stephen Wiesner, Charles Bennett and Gilles Brassard showed how quantum physics could be harnessed to provide information-theoretic security for protocols such as the distribution of cryptographic keys, which enables two parties to secure their conventional communications. Bennett and Brassard and colleagues performed a proof-of-principle quantum key distribution (QKD) experiment with single-photon quantum state transmission over a 32-cm air path in 1991. This seminal experiment led other researchers to explore QKD in optical fibers and over line-of-sight outdoor atmospheric paths (``free-space''), resulting in dramatic increases in range, bit rate and security. These advances have been enabled by improvements in sources and single-photon detectors. Also in 1991 Artur Ekert showed how the security of QKD could be related to quantum entanglement. This insight led to a deeper understanding and proof of QKD security with practical sources and detectors in the presence of transmission loss and channel noise. Today, QKD has been implemented over ranges much greater than 100km in both fiber and free-space, multi-node network testbeds have been demonstrated, and satellite-based QKD is under study in several countries. ``Quantum hacking'' researchers have shown the importance of extending security considerations to the classical devices that produce and detect the photon quantum states. New quantum cryptographic protocols such as secure identification have been proposed, and others such as quantum secret splitting have been demonstrated. It is now possible to envision quantum cryptography providing a more secure alternative to present-day cryptographic methods for many secure communications functions. My talk will survey these remarkable developments.

  6. Multiuser switched scheduling systems with per-user threshold and post-user selection

    KAUST Repository

    Nam, Haewoon

    2010-06-01

    A multiuser switched diversity scheduling scheme with per-user feedback threshold is proposed in this paper. Unlike the conventional multiuser switched diversity scheduling scheme where a single threshold is used by all the users in order to determine whether to transmit a feedback, the proposed scheme deploys per-user threshold, where each user uses a potentially different threshold than other users thresholds. This paper first provides a generic analytical framework for the optimal feedback thresholds in a closed form. Then we investigates the impact of user sequence strategies and post selection strategies on the performance of the multiuser switched scheduling scheme with per-user threshold. Numerical and simulation results show that the proposed scheme provides a higher system capacity compared to the conventional scheme. © 2010 IEEE.

    We estimate the proportion of participants willing to pay the US price (€30) or €20 for an HIV self-test and analyse their associated factors. In a street-based testing program, 497 participants in a feasibility self-test study answered the question, "What would be the maximum price you would be willing to pay for a similar test to this one so you can use it at your convenience?" Only 17.9% would pay ≥€30, while 40.0%, ≥€20. In the logistic regression, paying more was associated with being tested outside the campuses and having paid or been paid for sex. In Spain, self-testing would not have an impact unless it became more affordable to potential users.

    This project is aimed to support external users for the effective use of HANARO. The total number of projects selected as the beneficiary of the supporting program by MEST was 21 including this project in this year. We supported 2,339 hr measurements for the 31 requests of the 14 projects selected on the field of neutron beam utilization. In the field of materials and nuclear fuel irradiation test the 3 projects were selected and supported for 80 samples. In the fields of neutron activation analysis and radioisotope production the number of selected and supported projects were 1 and 2 respectively. In order to broaden potential user base, maximize instrument utilization, and enhance cooperation with industries, universities and institutes, practice-oriented HANARO user training courses were held for neutron beam utilization and materials and nuclear fuel irradiation fields. In the fields of neutron activation analysis 3 times training courses were held for the university students. The online neutron beam time allocation system was developed and applied successfully for the HRPD in this year. We are planing to apply this system to other neutron beam instruments in the near future. This project is a kind of the user-based supporting program for the maximize of HANARO utilization. The development products and the ideas and suggestions of users obtained through this projects will be collected and applied to the development of next new facilities. Also, by using the 'HANARO utilization and research information management system(HANARO4U)' we construct the research network among users at industries, universities and institutes. This network is expected to increase HANARO utilization and enhance productivity of the facilities.

Oxycodone HCl-niacin tablets combine oxycodone HCl with niacin and functional inactive excipients to create potential barriers to oral, intranasal, and intravenous abuse. This study compared the relative abuse potential of oral immediate-release oxycodone HCl-niacin with that of oral immediate-release oxycodone HCl and placebo in nondependent, recreational opioid users.Methods: Forty-nine participants received oxycodone HCl-niacin 40/240 mg and 80/480 mg, oxycodone 40 mg and 80 mg, and placebo in a randomized, double-blind, placebo-controlled and active-controlled, five-way crossover study. Primary endpoints based on a bipolar 100 mm visual analog scale for drug liking were area under effect curve (AUE0–1h, AUE0–2h, AUE0–3h, peak disliking, and effect at 0.5 hours post-dose (E0.5h. Other endpoints included take drug again assessment, overall drug liking, and pupillometry.Results: There were statistically significant differences between oxycodone HCl-niacin and oxycodone HCl doses for all primary endpoints (P < 0.0001, all comparisons, suggesting reduced abuse potential with oxycodone HCl-niacin. Take drug again and overall drug liking showed greater liking of oxycodone alone. Oxycodone HCl-niacin 80/480 mg had consistently lower liking assessments than oxycodone HCl-niacin 40/240 mg, suggesting a dose-response to the aversive effects of niacin. Opioid-related adverse events were similar for equivalent oxycodone doses. The treatment-emergent adverse events most specifically associated with oxycodone HCl-niacin (ie, skin-burning sensation, warmth, and flushing were consistent with the expected vasocutaneous effects of

    User engagement refers to the quality of the user experience that emphasizes the positive aspects of interacting with an online application and, in particular, the desire to use that application longer and repeatedly. User engagement is a key concept in the design of online applications (whether for desktop, tablet or mobile), motivated by the observation that successful applications are not just used, but are engaged with. Users invest time, attention, and emotion in their use of technology, and seek to satisfy pragmatic and hedonic needs. Measurement is critical for evaluating whether online

    Acanthamoebae are the causative agents of an often seriously progressing keratitis (AK) occurring predominantly in contact lens wearers and can cause several disseminating infections potentially resulting in granulomatous amoebic encephalitis (GAE) in the immunocompromised host. Our institution is the Austrian reference laboratory for Acanthamoeba diagnostics and the aim of this study was to give an overview of proven cases of Acanthamoeba infections in Austria during the past 20 yr. All samples of patients with suspected AK or GAE were screened for Acanthamoeba spp. by culture and/or PCR and the detected amoebae were genotyped. Altogether, 154 cases of AK and three cases of GAE were diagnosed. Age of the AK patients ranged from 8 to 82 yr (mean 37.8) and 58% of the patients were female. Approximately 89% of the AK patients were contact lens wearers, almost all cases were unilateral and 19% of the patients required a keratoplasty. Age of the GAE patients ranged from 2 to 25 yr (mean 14.7), all were HIV-negative, but two were severely immunosuppressed at the time of diagnosis. The predominant genotype in the AK cases was T4, other genotypes found were T3, T5, T6, T10 and T11. The three GAE cases involved genotypes T2, T4 and T5.

  16. The deep, hot biosphere: Twenty-five years of retrospection.

    Twenty-five years ago this month, Thomas Gold published a seminal manuscript suggesting the presence of a "deep, hot biosphere" in the Earth's crust. Since this publication, a considerable amount of attention has been given to the study of deep biospheres, their role in geochemical cycles, and their potential to inform on the origin of life and its potential outside of Earth. Overwhelming evidence now supports the presence of a deep biosphere ubiquitously distributed on Earth in both terrestrial and marine settings. Furthermore, it has become apparent that much of this life is dependent on lithogenically sourced high-energy compounds to sustain productivity. A vast diversity of uncultivated microorganisms has been detected in subsurface environments, and we show that H2, CH4, and CO feature prominently in many of their predicted metabolisms. Despite 25 years of intense study, key questions remain on life in the deep subsurface, including whether it is endemic and the extent of its involvement in the anaerobic formation and degradation of hydrocarbons. Emergent data from cultivation and next-generation sequencing approaches continue to provide promising new hints to answer these questions. As Gold suggested, and as has become increasingly evident, to better understand the subsurface is critical to further understanding the Earth, life, the evolution of life, and the potential for life elsewhere. To this end, we suggest the need to develop a robust network of interdisciplinary scientists and accessible field sites for long-term monitoring of the Earth's subsurface in the form of a deep subsurface microbiome initiative.

  18. App Reviews: Breaking the User and Developer Language Barrier

    KAUST Repository

    Hoon, Leonard

    2015-10-22

    Apple, Google and third party developers offer apps across over twenty categories for various smart mobile devices. Offered exclusively through the App Store and Google Play, each app allows users to review the app and their experience with it. Current literature offers a general statistical picture of these reviews, and a broad overview of the nature of discontent of apps. However, we do not yet have a good framework to classify user reviews against known software quality attributes like performance or usability. In order to close this gap, in this paper, we develop an ontology encompassing software attributes derived from software quality models. This decomposes into approximately five thousand words that users employ to review apps. By identifying a consistent set of vocabulary that users communicate with, we can sanitise large datasets to extract stakeholder actionable information from reviews. The findings offered in this paper assists future app review analysis by bridging end-user communication and software engineering vocabulary.

  19. Twenty-Five Year Site Plan FY2013 - FY2037

    Energy Technology Data Exchange (ETDEWEB)

    Jones, William H. [Los Alamos National Laboratory

    2012-07-12

    Los Alamos National Laboratory (the Laboratory) is the nation's premier national security science laboratory. Its mission is to develop and apply science and technology to ensure the safety, security, and reliability of the United States (U.S.) nuclear stockpile; reduce the threat of weapons of mass destruction, proliferation, and terrorism; and solve national problems in defense, energy, and the environment. The fiscal year (FY) 2013-2037 Twenty-Five Year Site Plan (TYSP) is a vital component for planning to meet the National Nuclear Security Administration (NNSA) commitment to ensure the U.S. has a safe, secure, and reliable nuclear deterrent. The Laboratory also uses the TYSP as an integrated planning tool to guide development of an efficient and responsive infrastructure that effectively supports the Laboratory's missions and workforce. Emphasizing the Laboratory's core capabilities, this TYSP reflects the Laboratory's role as a prominent contributor to NNSA missions through its programs and campaigns. The Laboratory is aligned with Nuclear Security Enterprise (NSE) modernization activities outlined in the NNSA Strategic Plan (May 2011) which include: (1) ensuring laboratory plutonium space effectively supports pit manufacturing and enterprise-wide special nuclear materials consolidation; (2) constructing the Chemistry and Metallurgy Research Replacement Nuclear Facility (CMRR-NF); (3) establishing shared user facilities to more cost effectively manage high-value, experimental, computational and production capabilities; and (4) modernizing enduring facilities while reducing the excess facility footprint. Th is TYSP is viewed by the Laboratory as a vital planning tool to develop an effi cient and responsive infrastructure. Long range facility and infrastructure development planning are critical to assure sustainment and modernization. Out-year re-investment is essential for sustaining existing facilities, and will be re-evaluated on an annual

    In May 2005, SNV and the Ministry of Agriculture, Forestry and Fisheries (MAFF) agreed to a joint development of a National Biodigester Programme (NBP) in Cambodia as a way to create an indigenous, sustainable energy source in the country and to utilize the potential of biogas in the country. The overall objective of the first phase of the National Biodigester Programme is 'The dissemination of domestic biodigesters as an indigenous, sustainable energy source through the development of a commercial, market oriented, biodigester sector in selected provinces of Cambodia'. The program aims to support the construction of 17,500 biodigesters in at least 6 provinces over the period of 2006 to 2009. To gain insights and feedbacks on the impacts of their activities to date, NBP commissioned the Cambodia Institute of Development Study (CIDS) to carry out a Biodigester User Survey in January 2007. The purpose of the survey is to evaluate the effects of domestic biodigester installations, as supported by the program, on 100 households in 3 provinces in Cambodia- Kampong Cham, Kandal and Svay Rieng.

    Harvey, Dustin Yewell [Los Alamos National Lab. (LANL), Los Alamos, NM (United States)

    2016-06-06

    Echo™ is a MATLAB-based software package designed for robust and scalable analysis of complex data workflows. An alternative to tedious, error-prone conventional processes, Echo is based on three transformative principles for data analysis: self-describing data, name-based indexing, and dynamic resource allocation. The software takes an object-oriented approach to data analysis, intimately connecting measurement data with associated metadata. Echo operations in an analysis workflow automatically track and merge metadata and computation parameters to provide a complete history of the process used to generate final results, while automated figure and report generation tools eliminate the potential to mislabel those results. History reporting and visualization methods provide straightforward auditability of analysis processes. Furthermore, name-based indexing on metadata greatly improves code readability for analyst collaboration and reduces opportunities for errors to occur. Echo efficiently manages large data sets using a framework that seamlessly allocates resources such that only the necessary computations to produce a given result are executed. Echo provides a versatile and extensible framework, allowing advanced users to add their own tools and data classes tailored to their own specific needs. Applying these transformative principles and powerful features, Echo greatly improves analyst efficiency and quality of results in many application areas.

  5. User Frustrations as Opportunities

    Directory of Open Access Journals (Sweden)

    Michael Weiss

    2012-04-01

    Full Text Available User frustrations are an excellent source of new product ideas. Starting with this observation, this article describes an approach that entrepreneurs can use to discover business opportunities. Opportunity discovery starts with a problem that the user has, but may not be able to articulate. User-centered design techniques can help elicit those latent needs. The entrepreneur should then try to understand how users are solving their problem today, before proposing a solution that draws on the unique skills and technical capabilities available to the entrepreneur. Finally, an in-depth understanding of the user allows the entrepreneur to hone in on the points of difference and resonance that are the foundation of a strong customer value proposition.

  14. Twenty Meter Space Telescope Based on Diffractive Fresnel Lens

    Energy Technology Data Exchange (ETDEWEB)

    Early, J; Hyde, R; Baron, R

    2003-06-26

    Diffractive lenses offer two potential advantages for very large aperture space telescopes; very loose surface-figure tolerances and physical implementation as thin, flat optical elements. In order to actually realize these advantages one must be able to build large diffractive lenses with adequate optical precision and also to compactly stow the lens for launch and then fully deploy it in space. We will discuss the recent fabrication and assembly demonstration of a 5m glass diffractive Fresnel lens at LLNL. Optical performance data from smaller full telescopes with diffractive lens and corrective optics show diffraction limited performance with broad bandwidths. A systems design for a 20m space telescope will be presented. The primary optic can be rolled to fit inside of the standard fairings of the Delta IV vehicle. This configuration has a simple deployment and requires no orbital assembly. A twenty meter visible telescope could have a significant impact in conventional astronomy with eight times the resolution of Hubble and over sixty times the light gathering capacity. If the light scattering is made acceptable, this telescope could also be used in the search for terrestrial planets.

The present work studied the potential biological activity of twenty-seven monoterpenes, including monoterpene hydrocarbons and oxygenated ones, against seed germination and subsequent primary radicle growth of Raphanus sativus L. (radish and Lepidium sativum L. (garden cress, under laboratory conditions. The compounds, belonging to different chemical classes, showed different potency in affecting both parameters evaluated. The assayed compounds demonstrated a good inhibitory activity in a dose-dependent way. In general, radish seed is more sensitive than garden cress and its germination appeares more inhibited by alcohols; at the highest concentration tested, the more active substances were geraniol, borneol, (±-β-citronellol and α-terpineol. Geraniol and carvone inhibited, in a significant way, the germination of garden cress, at the highest concentration tested. Radicle elongation of two test species was inhibited mainly by alcohols and ketones. Carvone inhibited the radicle elongation of both seeds, at almost all concentrations assayed, while 1,8-cineole inhibited their radicle elongation at the lowest concentrations (10−5 M, 10−6 M.

    1995-10-01

    Aztec is an iterative library that greatly simplifies the parallelization process when solving the linear systems of equations Ax = b where A is a user supplied n x n sparse matrix, b is a user supplied vector of length n and x is a vector of length n to be computed. Aztec is intended as a software tool for users who want to avoid cumbersome parallel programming details but who have large sparse linear systems which require an efficiently utilized parallel processing system. A collection of data transformation tools are provided that allow for easy creation of distributed sparse unstructured matrices for parallel solution. Once the distributed matrix is created, computation can be performed on any of the parallel machines running Aztec: nCUBE 2, IBM SP2 and Intel Paragon, MPI platforms as well as standard serial and vector platforms. Aztec includes a number of Krylov iterative methods such as conjugate gradient (CG), generalized minimum residual (GMRES) and stabilized biconjugate gradient (BICGSTAB) to solve systems of equations. These Krylov methods are used in conjunction with various preconditioners such as polynomial or domain decomposition methods using LU or incomplete LU factorizations within subdomains. Although the matrix A can be general, the package has been designed for matrices arising from the approximation of partial differential equations (PDEs). In particular, the Aztec package is oriented toward systems arising from PDE applications.

We argue that subjectivi- ties of information clarifies the relationships between de- sign choices and embodied experiences, ways that designers design users and not just products, and ways to cultivate and transform, rather than merely support, human agency.......—by laying out what it means and why research- ers are being drawn to it. We then use it to guide a case study of a relatively marginal use of computing—digitally mediated sexuality—to holistically explore design in rela- tion to embodiment, tactual experience, sociability, power, ideology, selfhood......Foundational to HCI is the notion of “the user.” Whether a cognitive processor, social actor, consumer, or even a non- user, the user in HCI has always been as much a technical construct as actual people using systems.

    1994-01-01

    The Flow Analysis Software Toolkit, FAST, is a software environment for visualizing data. FAST is a collection of separate programs (modules) that run simultaneously and allow the user to examine the results of numerical and experimental simulations. The user can load data files, perform calculations on the data, visualize the results of these calculations, construct scenes of 3D graphical objects, and plot, animate and record the scenes. Computational Fluid Dynamics (CFD) visualization is the primary intended use of FAST, but FAST can also assist in the analysis of other types of data. FAST combines the capabilities of such programs as PLOT3D, RIP, SURF, and GAS into one environment with modules that share data. Sharing data between modules eliminates the drudgery of transferring data between programs. All the modules in the FAST environment have a consistent, highly interactive graphical user interface. Most commands are entered by pointing and'clicking. The modular construction of FAST makes it flexible and extensible. The environment can be custom configured and new modules can be developed and added as needed. The following modules have been developed for FAST: VIEWER, FILE IO, CALCULATOR, SURFER, TOPOLOGY, PLOTTER, TITLER, TRACER, ARCGRAPH, GQ, SURFERU, SHOTET, and ISOLEVU. A utility is also included to make the inclusion of user defined modules in the FAST environment easy. The VIEWER module is the central control for the FAST environment. From VIEWER, the user can-change object attributes, interactively position objects in three-dimensional space, define and save scenes, create animations, spawn new FAST modules, add additional view windows, and save and execute command scripts. The FAST User Guide uses text and FAST MAPS (graphical representations of the entire user interface) to guide the user through the use of FAST. Chapters include: Maps, Overview, Tips, Getting Started Tutorial, a separate chapter for each module, file formats, and system

    1995-12-31

    This User`s Guide has been prepared to provide recommendations for the selection and application of climatic scenarios in the Finnish Research Programme on Climate Change (SILMU). These scenarios are required for conducting impact studies in SILMU. They should reflect the current range of estimates of future climate in the Finnish region. In addition, they should be consistent with other projections of importance in impact studies, such as future atmospheric composition and sea level. Section 2 provides some background information about the types of scenarios required in SILMU and Section 3 offers a general description of the scenarios. In Section 4 there is some advice on applying sensitivity studies to complement the use of scenarios. Section 5 explains the installation of the SILMUSCEN program and Section 6 guides the user through some examples to illustrate how SILMUSCEN can be used. Section 7 offers some recommendations on which scenarios to adopt for different impact assessments. In order to ensure some compatibility between impact studies in SILMU, it is very important that the recommendations in this section are followed as far as possible. Section 8 addresses important omissions from the computer program and suggests procedures to adopt in their absence. Section 9 explores alternative methods of specifying the baseline climate, and shows how scenario adjustments to the baseline can be made. in Section 10, the stochastic weather generator, CLIGEN, is described and its use illustrated by means of examples. Finally, possible refinements of the programs are outlined in Section 11, along with contact names and addresses for obtaining further information. (36 refs.)

    An analysis is presented of the uses of metadata from four aspects of database operations: (1) search, query, retrieval, (2) ingest, quality control, processing, (3) application to application transfer; (4) storage, archive. Typical degrees of database functionality ranging from simple file retrieval to interdisciplinary global query with metadatabase-user dialog and involving many distributed autonomous databases, are ranked in approximate order of increasing sophistication of the required knowledge representation. An architecture is outlined for implementing such functionality in many different disciplinary domains utilizing a variety of off the shelf database management subsystems and processor software, each specialized to a different abstract data model.

    2004-10-01

    To investigate the frequency of non-fatal cocaine overdose, and responses to overdoses, among injecting and non-injecting cocaine users. Cross-sectional study. Sydney, Australia. Two hundred current cocaine users. Structured interview. Thirteen per cent of the sample had overdosed on cocaine, 7% in the preceding 12 months. Cocaine injectors were more likely to have overdosed, both ever (17 v 6%) and in the preceding 12 months (9 v 3%). The most common symptoms of overdose were palpitations (68%), intense sweating (44%) and seizures (40%). The use of other drugs in combination with cocaine prior to the most recent overdose was prevalent (64%), most commonly opioids (40%), alcohol (24%) and cannabis (24%). Those who had overdosed were more likely to be female, had longer cocaine use careers, had used more cocaine in the preceding month and preceding 6 months, had higher levels of cocaine dependence and more extensive polydrug use. Twenty-four per cent had witnessed a cocaine overdose, 13% in the preceding 12 months. Injectors were more likely to have witnessed overdoses, both ever (35% v 8%) and in the preceding 12 months (20% v 3%). Experience of, and exposure to, overdose were not rare events. Cocaine users need to be aware of the possibility and nature of overdose, and that cocaine overdose can occur irrespective of method of use. There is a need to emphasise the potential danger of combining cocaine with other drugs.

    The Multi-Reactor Design and Analysis Platform (MRDAP) is designed to simplify the creation, transfer and processing of data between computational codes. MRDAP accomplishes these objectives with three parts: 1. allows each integrated code, through a plugin, to specify the required input for execution and the required output needed, 2. creates an interface for execution and data transfer, 3. enables the creation of Graphical User Interfaces (GUI) to assist with input preparation and data visualization. Ultimately, the main motivation of this work is to enable analysts (who perform reactor physics calculations routinely), by providing a tool that increases efficiency and minimizes the potential for errors or failed executions.

  3. Information Filtering Based on Users' Negative Opinions

    Science.gov (United States)

    Guo, Qiang; Li, Yang; Liu, Jian-Guo

    2013-05-01

    The process of heat conduction (HC) has recently found application in the information filtering [Zhang et al., Phys. Rev. Lett.99, 154301 (2007)], which is of high diversity but low accuracy. The classical HC model predicts users' potential interested objects based on their interesting objects regardless to the negative opinions. In terms of the users' rating scores, we present an improved user-based HC (UHC) information model by taking into account users' positive and negative opinions. Firstly, the objects rated by users are divided into positive and negative categories, then the predicted interesting and dislike object lists are generated by the UHC model. Finally, the recommendation lists are constructed by filtering out the dislike objects from the interesting lists. By implementing the new model based on nine similarity measures, the experimental results for MovieLens and Netflix datasets show that the new model considering negative opinions could greatly enhance the accuracy, measured by the average ranking score, from 0.049 to 0.036 for Netflix and from 0.1025 to 0.0570 for Movielens dataset, reduced by 26.53% and 44.39%, respectively. Since users prefer to give positive ratings rather than negative ones, the negative opinions contain much more information than the positive ones, the negative opinions, therefore, are very important for understanding users' online collective behaviors and improving the performance of HC model.

  6. User`s guide to ESME v. 8.1

    Energy Technology Data Exchange (ETDEWEB)

    MacLachlan, J.

    1993-08-26

    ESME is a computer program to calculate the evolution of a distribution of particles in energy and azimuth as it is acted upon by the radio frequency system of a proton synchrotron. It provides for the modeling of multiple rf systems, feedback control, space charge, and many of the effects of longitudinal coupling impedance. The capabilities of the program are described, and the requirements for input data are specified in sufficient detail to permit significant calculations by an uninitiated user. The program is currently at version 8.1 and extensively modified since the previous user documentation. Changes since the 7.xx versions include a new command and associated parameters for mapping phase space flow lines, new names for a few parameters, and a few new parameters for old commands. Special attention has been given to features relating to calculation of the collective potential and the generation of phase space trajectories including its effects. The VAX-based code management convention has been modified slightly to permit pre-compile options to be used in the include files as well as the program source files. The biggest change from v. 8.0 to v. 8.1 is the addition of code for HIGZ-based graphics; the new code and that using DI3000/GRAFMAKER are alternatives selectable at compilation. Other changes relate to improved control of smoothing options in the calculation of collective potential, fourier spectra, and mountain range plots.

  7. User Authorization at the Molecular Scale.

    2017-07-05

    Electronic user authorization systems help us maintain our privacy in many aspects of everyday life. However, the increasing difficulty to secure access and/or information digitally has inspired chemists to devise alternative, molecular approaches, in which users are identified by chemical means. The potential advantages of using molecular user authentication systems over conventional electronic devices are their versatility and unusual operating principles, which complicate replicating and, consequently, breaking into molecular security devices. Their molecular scale is another unique property that enables hiding such systems and, consequently, applying steganography as an additional layer of protection. Although the area of molecular-based user authorization is still in its infancy, the development of various molecular keypad locks and, more recently, a password-protected molecular cryptographic machine, indicate the possibility of protecting information at the molecular scale. © 2017 Wiley-VCH Verlag GmbH & Co.

    Jay, Caroline; Lunn, Darren; Michailidou, Eleni

    As new technologies emerge, and Web sites become increasingly sophisticated, ensuring they remain accessible to disabled and small-screen users is a major challenge. While guidelines and automated evaluation tools are useful for informing some aspects of Web site design, numerous studies have demonstrated that they provide no guarantee that the site is genuinely accessible. The only reliable way to evaluate the accessibility of a site is to study the intended users interacting with it. This chapter outlines the processes that can be used throughout the design life cycle to ensure Web accessibility, describing their strengths and weaknesses, and discussing the practical and ethical considerations that they entail. The chapter also considers an important emerging trend in user evaluations: combining data from studies of “standard” Web use with data describing existing accessibility issues, to drive accessibility solutions forward.

    The OASIS system has been operational for years now. After a long development the project has reached a state where the number of features it provides exceeds largely what most of its users knows about. The author felt it was time to write a user manual explaining all the functionality of the viewer application. This document is a user manual, concentrating on the functionality of the viewer from the user’s point of view. There are already documents available on the project’s web site about the technical aspects at http://project-oasis.web.cern.ch/project-oasis/presentations.htm . There was an attempt to produce a tutorial on the viewer, but it didn’t get much further than the table of contents, that however is well thought. The structure of this user manual follows the same principle, the basic and most often used features are grouped together. Advanced or less often used features are described in a separate chapter. There is a second organizational principle, features belong to different levels: chann...

    Power User Interface 5.0 (PUI) is a system of middleware, written for expert users in the Earth-science community, PUI enables expedited ordering of data granules on the basis of specific granule-identifying information that the users already know or can assemble. PUI also enables expert users to perform quick searches for orderablegranule information for use in preparing orders. PUI 5.0 is available in two versions (note: PUI 6.0 has command-line mode only): a Web-based application program and a UNIX command-line- mode client program. Both versions include modules that perform data-granule-ordering functions in conjunction with external systems. The Web-based version works with Earth Observing System Clearing House (ECHO) metadata catalog and order-entry services and with an open-source order-service broker server component, called the Mercury Shopping Cart, that is provided separately by Oak Ridge National Laboratory through the Department of Energy. The command-line version works with the ECHO metadata and order-entry process service. Both versions of PUI ultimately use ECHO to process an order to be sent to a data provider. Ordered data are provided through means outside the PUI software system.

    SHARP is an advanced modeling and simulation toolkit for the analysis of nuclear reactors. It is comprised of several components including physical modeling tools, tools to integrate the physics codes for multi-physics analyses, and a set of tools to couple the codes within the MOAB framework. Physics modules currently include the neutronics code PROTEUS, the thermal-hydraulics code Nek5000, and the structural mechanics code Diablo. This manual focuses on performing multi-physics calculations with the SHARP ToolKit. Manuals for the three individual physics modules are available with the SHARP distribution to help the user to either carry out the primary multi-physics calculation with basic knowledge or perform further advanced development with in-depth knowledge of these codes. This manual provides step-by-step instructions on employing SHARP, including how to download and install the code, how to build the drivers for a test case, how to perform a calculation and how to visualize the results. Since SHARP has some specific library and environment dependencies, it is highly recommended that the user read this manual prior to installing SHARP. Verification tests cases are included to check proper installation of each module. It is suggested that the new user should first follow the step-by-step instructions provided for a test problem in this manual to understand the basic procedure of using SHARP before using SHARP for his/her own analysis. Both reference output and scripts are provided along with the test cases in order to verify correct installation and execution of the SHARP package. At the end of this manual, detailed instructions are provided on how to create a new test case so that user can perform novel multi-physics calculations with SHARP. Frequently asked questions are listed at the end of this manual to help the user to troubleshoot issues.

    Zillig, David; Weinberg, Aaron; Mcomber, Robert

    1994-01-01

    The Tracking and Data Relay Satellite System (TDRSS) has long been used to provide reliable low and high-data rate relay services between user spacecraft in Earth orbit and the ground. To date, these TDRSS services have been implemented via prior scheduling based upon estimates of user needs and mission event timelines. While this approach may be necessary for large users that require greater amounts of TDRSS resources, TDRSS can potentially offer the planned community of smaller science missions (e.g., the small explorer missions), and other emerging users, the unique opportunity for services on demand. In particular, innovative application of the existing TDRSS Multiple Access (MA) subsystem, with its phased array antenna, could be used to implement true demand access services without modification to either the TDRSS satellites or the user transponder, thereby introducing operational and performance benefits to both the user community and the Space Network. In this paper, candidate implementations of demand access service via the TDRSS MA subsystem are examined in detail. Both forward and return link services are addressed and a combination of qualitative and quantitative assessments are provided. The paper also identifies further areas for investigation in this ongoing activity that is being conducted by GSFC/Code 531 under the NASA Code O Advanced Systems Program.

  11. 一种基于用户偏好自动分类的社会媒体共享和推荐方法%A User Preference Based Automatic Potential Group Generation Method for Social Media Sharing and Recommendation

    2012-01-01

    Social media applications have become the mainstream of Web application. User-oriented and content generated by users are pivotal characteristics of social media sites. Data sharing and recommendation approaches play an important role in dealing with the problem of information overload in social media environment. In this paper, we analyze the flaws of current group-based information sharing mechanism and the common problem of traditional recommender approaches, and then we propose a novel approach of group automatic generating for social media sharing and recommendation. Intuitively, the essential idea of our approach is that we switch user's preference from the media objects to the interest elements which media objects imply. Then we gather the users who have common preference, namely users have the same interestingness in a set of interest elements, together as Common Preference Group (CPG). We also propose a new social media data sharing and recommendation system architecture based on CPG and design a CPG automatic mining algorithm. By compare our CPG mining algorithm with other algorithm which has similar functionality, it is shown that our algorithm could be applicable to real social media application with massive users.%社会媒体应用已成为Web应用的主流,以用户为中心并且海量媒体数据由用户自生成是社会媒体Web应用的重要特征.应对目前社会媒体环境中信息过载的问题,信息的共享和推荐机制发挥着重要的作用.文中分析了目前主流社会媒体网站基于用户自建组的信息共享机制所存在的问题以及传统推荐技术在效率上的问题,提出了一种新的基于用户偏好自动分类的社会媒体数据共享和推荐方法.直观上讲,该方法的本质是把用户对具体媒体对象的偏好转化成用户对媒体对象所蕴含兴趣元素的偏好,然后把具有相同偏好的用户,即对若干兴趣元素上的兴趣度都相同,自动聚

    Exactly twenty five years ago the world of high energy physics was set on fire by the discovery of a new particle with an unusually narrow width at 3095 MeV, known popularly as the $J/\\Psi$ revolution. This discovery was very decisive in our understanding as well as formulating the current picture regarding the basic constituents of nature. I look back at the discovery, pointing out how unexpected, dramatic and significant it was.

  13. Early twenty-first-century droughts during the warmest climate

    Directory of Open Access Journals (Sweden)

    Felix Kogan

    2016-01-01

    Full Text Available The first 13 years of the twenty-first century have begun with a series of widespread, long and intensive droughts around the world. Extreme and severe-to-extreme intensity droughts covered 2%–6% and 7%–16% of the world land, respectively, affecting environment, economies and humans. These droughts reduced agricultural production, leading to food shortages, human health deterioration, poverty, regional disturbances, population migration and death. This feature article is a travelogue of the twenty-first-century global and regional droughts during the warmest years of the past 100 years. These droughts were identified and monitored with the National Oceanic and Atmospheric Administration operational space technology, called vegetation health (VH, which has the longest period of observation and provides good data quality. The VH method was used for assessment of vegetation condition or health, including drought early detection and monitoring. The VH method is based on operational satellites data estimating both land surface greenness (NDVI and thermal conditions. The twenty-first-century droughts in the USA, Russia, Australia and Horn of Africa were intensive, long, covered large areas and caused huge losses in agricultural production, which affected food security and led to food riots in some countries. This research also investigates drought dynamics presenting no definite conclusion about drought intensification or/and expansion during the time of the warmest globe.

  16. Accessible Capacity of Secondary Users

    CERN Document Server

    Ma, Xiao; Lin, Lei; Bai, Baoming

    2010-01-01

    A new problem formulation is presented for the Gaussian interference channels (GIFC) with two pairs of users, which are distinguished as primary users and secondary users, respectively. The primary users employ a pair of encoder and decoder that were originally designed to satisfy a given error performance requirement under the assumption that no interference exists from other users. In the case when the secondary users attempt to access the same medium, we are interested in the maximum transmission rate (defined as {\\em accessible capacity}) at which secondary users can communicate reliably without affecting the error performance requirement by the primary users under the constraint that the primary encoder (not the decoder) is kept unchanged. By modeling the primary encoder as a generalized trellis code (GTC), we are then able to treat the secondary link as a finite state channel (FSC). The relation of the accessible capacity to the capacity region of the GIFC is revealed. Upper and lower bounds on the acce...

  17. User Privacy in RFID Networks

    Science.gov (United States)

    Singelée, Dave; Seys, Stefaan

    Wireless RFID networks are getting deployed at a rapid pace and have already entered the public space on a massive scale: public transport cards, the biometric passport, office ID tokens, customer loyalty cards, etc. Although RFID technology offers interesting services to customers and retailers, it could also endanger the privacy of the end-users. The lack of protection mechanisms being deployed could potentially result in a privacy leakage of personal data. Furthermore, there is the emerging threat of location privacy. In this paper, we will show some practical attack scenarios and illustrates some of them with cases that have received press coverage. We will present the main challenges of enhancing privacy in RFID networks and evaluate some solutions proposed in literature. The main advantages and shortcomings will be briefly discussed. Finally, we will give an overview of some academic and industrial research initiatives on RFID privacy.

  18. Looking beyond the illness: forensic service users' perceptions of rehabilitation.

    Science.gov (United States)

    Barnao, Mary; Ward, Tony; Casey, Sharon

    2015-03-01

    The aim of this qualitative study was to explore perspectives on rehabilitation of those detained in a New Zealand forensic hospital setting. Twenty forensic service users participated in individual interviews, which were audio-taped, transcribed verbatim, and subjected to thematic analysis. The analysis identified seven themes that were broadly categorized into those that concerned the rehabilitation context (external) and those that more directly reflected the forensic service user's personal experience (internal). External themes highlighted a person-centered approach, the nature of relationships with staff, consistency of care, and awareness of the rehabilitation pathway. Internal themes related to forensic service users' self-evaluations, agency, and coping strategies. These findings are discussed within the broader context in which rehabilitation took place.

  19. User Control Problems and Taking User Empowerment Further

    Science.gov (United States)

    Rodrigues, Rowena

    User control in identity management is beset with a number of problems, as outlined in this paper. It is argued that akin to traditional contexts, greater user control will result in greater user liability, which is demonstrated with the help of digital and non-digital examples. In this context, there is a critical need for greater user empowerment. This could be achieved in two ways-first, facilitating user awareness of identity management technologies, their scope and effects and second, through the implementation of proposed control-liability notices.

    There is an important role of the users that are traversing Internet resources and their activities which, according to the practice, aren't usually considered by the Internet resource owners so to adjust and optimize hypertext structure. Optimal hypertext structure allows users to locate pages of interest, which are the goals of the informational search, in a faster way. Paper presents a model that conducts user auditory behavior analysis in order to figure out their goals in particular hypertext segment and allows finding out optimal routes for reaching those goals in terms of the routes length and informational value. Potential application of the proposed model is mostly the systems that evaluate hypertext networks and optimize their referential structure for faster information retrieval.

    Schmitt, Harrison H.

    1986-01-01

    Existing international space law as well as the best interest of all nations are consistent with the establishment of a user-based international organization, herein called INTERMARS. INTERMARS would provide access to facilities and services at a Martian base which would be of high functional potential, quality, safety, and reliability. These opportunities would be available on an open and nondiscriminatory basis to all peaceful users and investors. INTERMARS is a model organization concept tailored to provide cooperative international management of a Martian base for the benefit of its members, users, and investors. Most importantly, INTERMARS would provide such management through a sharing of both sovereignty and opportunity rather then unilateral control by any one nation or set of competing nations. Through an Assembly of Parties, a Board of Governors, a Board of Users and Investors, and a Director General, INTERMARS would meet its primary goal as it would be in the self-interest of all members, users, and investors to do so. The internal structure and philosophy of INTERMARS would provide not only for all participants to have representation in decisions affecting its activities, but also would insure effective and responsive management. Surely this is the precedent wished for, to establish for mankind at the now not-so-distant shores of the new ocean of space.

  9. Using virtual reality to assess user experience.

    Rebelo, Francisco; Noriega, Paulo; Duarte, Emília; Soares, Marcelo

    2012-12-01

    The aim of this article is to discuss how user experience (UX) evaluation can benefit from the use of virtual reality (VR). UX is usually evaluated in laboratory settings. However, considering that UX occurs as a consequence of the interaction between the product, the user, and the context of use, the assessment of UX can benefit from a more ecological test setting. VR provides the means to develop realistic-looking virtual environments with the advantage of allowing greater control of the experimental conditions while granting good ecological validity. The methods used to evaluate UX, as well as their main limitations, are identified.The currentVR equipment and its potential applications (as well as its limitations and drawbacks) to overcome some of the limitations in the assessment of UX are highlighted. The relevance of VR for UX studies is discussed, and a VR-based framework for evaluating UX is presented. UX research may benefit from a VR-based methodology in the scopes of user research (e.g., assessment of users' expectations derived from their lifestyles) and human-product interaction (e.g., assessment of users' emotions since the first moment of contact with the product and then during the interaction). This article provides knowledge to researchers and professionals engaged in the design of technological interfaces about the usefulness of VR in the evaluation of UX.

    Wu, Kesheng; Simon, H.

    1999-03-09

    TRLAN is a program designed to find a small number of extreme eigenvalues and their corresponding eigenvectors of a real symmetric matrix. Denote the matrix as A, the eigenvalue as {lambda}, and the corresponding eigenvector as x, they are defined by the following equation, Ax = {lambda}x. There are a number of different implementations of the Lanczos algorithm available. Why another one? Our main motivation is to develop a specialized version that only target the case where one wants both eigenvalues and eigenvectors of a large real symmetric eigenvalue problems that can not use the shift-and-invert scheme. In this case the standard non-restarted Lanczos algorithm requires one to store a large number of Lanczos vectors which can cause storage problem and make each iteration of the method very expensive. The underlying algorithm of TRLAN is a dynamic thick-restart Lanczos algorithm. Like all restarted methods, the user can choose how many vectors can be generated at once. Typically, th e user chooses a moderate size so that all Lanczos vectors can be stored in core. This allows the restarted methods to execute efficiently. This implementation of the thick-restart Lanczos method also uses the latest restarting technique, it is very effective in reducing the time required to compute a desired solutions compared to similar restarted Lanczos schemes, e.g., ARPACK.

    The results of a series of telephone interviews with groups of users of information on photovoltaics (PV) are described. These results, part of a larger study on many different solar technologies, identify types of information each group needed and the best ways to get information to each group. The report is 1 of 10 discussing study results. The overall study provides baseline data about information needs in the solar community. It covers these technological areas: photovoltaics, passive solar heating and cooling, active solar heating and cooling, biomass energy, solar thermal electric power, solar industrial and agricultural process heat, wind energy, ocean energy, and advanced energy storage. An earlier study identified the information user groups in the solar community and the priority (to accelerate solar energy commercialization) of getting information to each group. In the current study only high-priority groups were examined. Results from seven PV groups respondents are analyzed in this report: DOE-Funded Researchers, Non-DOE-Funded Researchers, Researchers Working for Manufacturers, Representatives of Other Manufacturers, Representatives of Utilities, Electric Power Engineers, and Educators.

    Topiramate is a neuromodulatory agent increasingly prescribed for a number of neurological and non-neurological indications. Topiramate-treated patients are at risk for nephrolithiasis due to hypocitraturia and high urine pH. However, the prevalence of symptomatic stone disease in TPM users is generally perceived to be low. This study was undertaken to assess in topiramate-treated patients the prevalence of symptomatic nephrolithiasis (by history) and of asymptomatic nephrolithiasis by computed tomography (CT) scan. Topiramate users were identified from a database of patients with neurological disorders at a single university hospital. Among 75 topiramate-treated adult patients with a median daily dose of 300 mg and median treatment duration of 48 months, the prevalence of symptomatic nephrolithiasis was 10.7%. In a subset of topiramate-treated patients and no history of symptomatic stone disease, the prevalence of asymptomatic nephrolithiasis detected by CT scan was 20%. The prevalence of symptomatic nephrolithiasis with long-term topiramate use is higher than reported in short-term studies. Furthermore, clinical prevalence is underestimated due to asymptomatic nephrolithiasis.

    In this work we present the results of a study of twenty natural pigments obtained from plants and insects from southern Ecuador. Many of them will be considered as a potential natural sensitizer for the construction of DSSCs. The results indicate that these pigments have a good performance in the absorbance and wavelength spectra. Were selected four best pigments for the construction of DSSCs, Rumex tolimensis Wedd, Raphanus sativus, Hibiscus sabdariffa, and Prunus serótina, however the conversion efficiency is lower than 1%.

  17. Multiuser switched diversity scheduling systems with per-user threshold

    KAUST Repository

    Nam, Haewoon

    2010-05-01

    A multiuser switched diversity scheduling scheme with per-user feedback threshold is proposed and analyzed in this paper. The conventional multiuser switched diversity scheduling scheme uses a single feedback threshold for every user, where the threshold is a function of the average signal-to-noise ratios (SNRs) of the users as well as the number of users involved in the scheduling process. The proposed scheme, however, constructs a sequence of feedback thresholds instead of a single feedback threshold such that each user compares its channel quality with the corresponding feedback threshold in the sequence. Numerical and simulation results show that thanks to the flexibility of threshold selection, where a potentially different threshold can be used for each user, the proposed scheme provides a higher system capacity than that for the conventional scheme. © 2006 IEEE.

    With infection once again a high priority for the UK National Health Service (NHS), the medical microbiology and infection-control services require increased technology resources and more multidisciplinary staff. Clinical care and health protection need a coordinated network of microbiology services working to consistent standards, provided locally by NHS Trusts and supported by the regional expertise and national reference laboratories of the new Health Protection Agency. Here, I outline my thoughts on the need for these new resources and the ways in which clinical microbiology services in the UK can best meet the demands of the twenty-first century.

    This report examines the past twenty years of energy market events and energy policies to determine what may be useful for the future. The author focuses on two important lessons that should have been learned but which the author feels have been seriously misunderstood. The first is that oil price shocks were a very big and very real problem for oil importing countries, a problem the has not gone away. The second is that automobile fuel economy regulation has worked and worked effectively to reduce oil consumption and the externalities associated with it, and can still work effectively in the future.

  1. Accelerators for the twenty-first century a review

    CERN Document Server

    Wilson, Edmund J N

    1990-01-01

    The development of the synchrotron, and later the storage ring, was based upon the electrical technology at the turn of this century, aided by the microwave radar techniques of World War II. This method of acceleration seems to have reached its limit. Even superconductivity is not likely to lead to devices that will satisfy physics needs into the twenty-first century. Unless a new principle for accelerating elementary particles is discovered soon, it is difficult to imagine that high-energy physics will continue to reach out to higher energies and luminosities.

    Some of the achievements of earth observations from past space missions are described. Also discussed are the achievements to be anticipated from currently approved and planned earth observation missions. In looking forward to what the objectives of earth observations from space are expected to be in the future, together with what technology is expected to enable, what the earth observing program will look like during the first part of the twenty-first century is discussed. It is concluded that a key part of this program will be long-term observations holistically viewing the earth system.

    Full Text Available The Surface Enhanced Raman Scattering (SERS effect was observed for the first time in 1974, but it was only considered a new effect three years later, hence, nearly twenty years ago. Since its discovery, a significant amount of investigations have been performed aiming at to clarify the nature of the observed enhancement, to improve the surface stability and to establish applications which nowadays range from the study of biomolecules to catalysis. Some of the more relevant aspects of this effect which have been examined across the last two decades are summarized in this paper which presents the introductory aspects of SERS alongside with several of its applications.

  5. Reducing Risky Security Behaviours: Utilising Affective Feedback to Educate Users

    Directory of Open Access Journals (Sweden)

    Lynsay A. Shepherd

    2014-11-01

    Full Text Available Despite the number of tools created to help end-users reduce risky security behaviours, users are still falling victim to online attacks. This paper proposes a browser extension utilising affective feedback to provide warnings on detection of risky behaviour. The paper provides an overview of behaviour considered to be risky, explaining potential threats users may face online. Existing tools developed to reduce risky security behaviours in end-users have been compared, discussing the success rates of various methodologies. Ongoing research is described which attempts to educate users regarding the risks and consequences of poor security behaviour by providing the appropriate feedback on the automatic recognition of risky behaviour. The paper concludes that a solution utilising a browser extension is a suitable method of monitoring potentially risky security behaviour. Ultimately, future work seeks to implement an affective feedback mechanism within the browser extension with the aim of improving security awareness.

  12. Strategies for Teaching Maritime Archaeology in the Twenty First Century

    Science.gov (United States)

    Staniforth, Mark

    2008-12-01

    Maritime archaeology is a multi-faceted discipline that requires both theoretical learning and practical skills training. In the past most universities have approached the teaching of maritime archaeology as a full-time on-campus activity designed for ‘traditional’ graduate students; primarily those in their early twenties who have recently come from full-time undergraduate study and who are able to study on-campus. The needs of mature-age and other students who work and live in different places (or countries) and therefore cannot attend lectures on a regular basis (or at all) have largely been ignored. This paper provides a case study in the teaching of maritime archaeology from Australia that, in addition to ‘traditional’ on-campus teaching, includes four main components: (1) learning field methods through field schools; (2) skills training through the AIMA/NAS avocational training program; (3) distance learning topics available through CD-ROM and using the Internet; and (4) practicums, internships and fellowships. The author argues that programs to teach maritime archaeology in the twenty first century need to be flexible and to address the diverse needs of students who do not fit the ‘traditional’ model. This involves collaborative partnerships with other universities as well as government underwater cultural heritage management agencies and museums, primarily through field schools, practicums and internships.

    J-Earth is a Geographic Information Systems (GIS) application used for viewing and processing satellite and airborne remote sensing data and includes NASA imagery such as ASTER, Landsat, MODIS, TIMS, as well as other geological, ecological, and social datasets. The J-Earth team is working with the National Science Foundation-funded Central Arizona-Phoenix Long Term Ecological Research Project (CAP LTER) to incorporate its data and develop functionality for J-Earth. J-Earth was developed by the Arizona State University Mars Space Flight Facility as part of the JMARS (Java Mission-planning and Analysis for Remote Sensing) suite of open-source tools. J-Earth has been enhanced to support the needs of CAP LTER users with the use of web tutorials, social networking, user surveys and interviews. CAP LTER consists of an interdisciplinary urban ecology research group with different needs in the area of socio-ecological systems. Adapting J-Earth for the CAP LTER community has provided a test of J-Earth’s functionality for interdisciplinary datasets and has shown the potential for expanding J-Earth to include future users within the entire LTER network. This project could potentially be expanded to bring data from the other twenty-six LTER sites into J-Earth. J-Earth utilizes the analytical tools of JMARS and makes them available to a broad range of users. J-Earth utilizes a layered system to view data from different sources that can be exported, scaled, colored and superimposed for quick comparisons. The functionality of JMARS is focused on the planetary geology community, while J-Earth has the potential to be used by geologists, geographers, sociologists, and ecologists as well as policy makers. This presentation will provide an overview of information and feedback gathered from users of J-Earth, especially those of the CAP LTER. Collecting additional feedback in the form of social networking, interviews, trainings, and tutorials will help make J-Earth more functional and

    Åkerberg, Anna; Söderlund, Anne; Lindén, Maria

    2017-01-01

    Background Different kinds of physical activity (PA) self-monitoring technologies are used today to monitor and motivate PA behavior change. The user focus is essential in the development process of this technology, including potential future users such as representatives from the group of non-users. There is also a need to study whether there are differences between the groups of users and non-users. The aims of this study were to investigate possible differences between users and non-users regarding their opinions about PA self-monitoring technologies and to investigate differences in demographic variables between the groups. Materials and methods Participants were randomly selected from seven municipalities in central Sweden. In total, 107 adults responded to the Physical Activity Products Questionnaire, which consisted of 22 questions. Results Significant differences between the users and non-users were shown for six of the 20 measurement-related items: measures accurately (p=0.007), measures with high precision (p=0.024), measures distance (p=0.020), measures speed (p=0.003), shows minutes of activity (p=0.004), and shows geographical position (p=0.000). Significant differences between the users and non-users were also found for two of the 29 encouragement items: measures accurately (p=0.001) and has long-term memory (p=0.019). Significant differences between the groups were also shown for level of education (p=0.030) and level of physical exercise (p=0.037). Conclusion With a few exceptions, the users and the non-users in this study had similar opinions about PA self-monitoring technologies. Because this study showed significant differences regarding level of education and level of physical exercise, these demographic variables seemed more relevant to investigate than differences in opinions about the PA self-monitoring technologies.

    The twenty-first century has brought new opportunities and challenges to yeast culture collections, whether they are long-standing or recently established. Basic functions such as archiving, characterizing and distributing yeasts continue, but with expanded responsibilities and emerging opportunities. In addition to a number of well-known, large public repositories, there are dozens of smaller public collections that differ in the range of species and strains preserved, field of emphasis and services offered. Several collections have converted their catalogues to comprehensive databases and synchronize them continuously through public services, making it easier for users worldwide to locate a suitable source for specific yeast strains and the data associated with these yeasts. In-house research such as yeast taxonomy continues to be important at culture collections. Because yeast culture collections preserve a broad diversity of species and strains within a species, they are able to make discoveries in many other areas as well, such as biotechnology, functional, comparative and evolution genomics, bioprocesses and novel products. Due to the implementation of the Convention of Biological Diversity (CBD) and the Nagoya Protocol (NP), there are new requirements for both depositors and users to ensure that yeasts were collected following proper procedures and to guarantee that the country of origin will be considered if benefits arise from a yeast's utilization. Intellectual property rights (IPRs) are extremely relevant to the current access and benefit-sharing (ABS) mechanisms; most research and development involving genetic resources and associated traditional knowledge will be subject to this topic.

  5. Uncertainties in sea level projections on twenty-year timescales

    2016-04-01

    Regional decadal changes in sea level are governed by various processes, including ocean dynamics, gravitational and solid earth responses, mass loss of continental ice, and other local coastal processes. In order to improve predictions and physical attribution in decadal sea level trends, the uncertainties of each processes must be reflected in the sea level calculations. Here we explore uncertainties in predictions of the decadal and bi-decadal changes in regional sea level induced by the changes in ocean dynamics and associated redistribution of heat and freshwater (often referred to as dynamic sea level). Such predictions are typically based on the solutions from coupled atmospheric and oceanic general circulation models, including a suite of climate models participating in phase 5 of the Coupled Model Intercompasion Project (CMIP5). Designed to simulate long-term ocean variability in response to warming climate due to increasing green-house gas concentration ("forced" response), CMIP5 are deficient in simulating variability at shorter time scales. In contrast, global observations of sea level are available during a relatively short time span (e.g., twenty-year altimetry records), and are dominated by an "unforced" variability that occurs freely (internally) within the climate system. This makes it challenging to examine how well observations compare with model simulations. Therefore, here we focus on patterns and spatial characteristics of projected twenty-year trends in dynamic sea level. Based on the ensemble of CMIP5 models, each comprising a 240-year run, we compute an envelope of twenty-year rates, and analyze the spread and spatial relationship among predicted rates. An ensemble root-mean-square average exhibits large-scale spatial patterns, with the largest uncertainties found over mid and high latitudes that could be attributed to the changes in wind patterns and buoyancy forcing. To understand and parameterize spatial characteristics of the

    Handheld technology finds slowly its place in the healthcare world. Some clinicians already use intensively dedicated mobile applications to consult clinical references. However, handheld technology hasn't still broadly embraced to the core of the healthcare business, the hospitals. The weak penetration of handheld technology in the hospitals can be partly explained by the caution of stakeholders that must be convinced about the efficiency of these tools before going forward. In a domain where temporal constraints are increasingly strong, caregivers cannot loose time on playing with gadgets. All users are not comfortable with tactile manipulations and the lack of dedicated peripheral complicates entering data for novices. Stakeholders must be convinced that caregivers will be able to master handheld devices. In this paper, we make the assumption that the proper design of an interface may influence users' performances to record information. We are also interested to find out whether users increase their efficiency when using handheld tools repeatedly. To answer these questions, we have set up a field study to compare users' performances on three different user interfaces while recording vital signs. Some user interfaces were familiar to users, and others were totally innovative. Results showed that users' familiarity with smartphone influences their performances and that users improve their performances by repeating a task.

    Traditionally the interaction between users and the Grid is done with command line tools. However, these tools are difficult to use by non-expert users providing minimal help and generating outputs not always easy to understand especially in case of errors. Graphical User Interfaces are typically limited to providing access to the monitoring or accounting information and concentrate on some particular aspects failing to cover the full spectrum of grid control tasks. To make the Grid more user friendly more complete graphical interfaces are needed. Within the DIRAC project we have attempted to construct a Web based User Interface that provides means not only for monitoring the system behavior but also allows to steer the main user activities on the grid. Using DIRAC's web interface a user can easily track jobs and data. It provides access to job information and allows performing actions on jobs such as killing or deleting. Data managers can define and monitor file transfer activity as well as check requests set by jobs. Production managers can define and follow large data productions and react if necessary by stopping or starting them. The Web Portal is build following all the grid security standards and using modern Web 2.0 technologies which allow to achieve the user experience similar to the desktop applications. Details of the DIRAC Web Portal architecture and User Interface will be presented and discussed.

    The TMAP Code was written at the Idaho National Engineering and Environmental Laboratory by Brad Merrill and James Jones in the late 1980s as a tool for safety analysis of systems involving tritium. Since then it has been upgraded to TMAP4 and has been used in numerous applications including experiments supporting fusion safety, predictions for advanced systems such as the International Thermonuclear Experimental Reactor (ITER), and estimates involving tritium production technologies. Its further upgrade to TMAP2000 and now to TMAP7 was accomplished in response to several needs. TMAP and TMAP4 had the capacity to deal with only a single trap for diffusing gaseous species in solid structures. TMAP7 includes up to three separate traps and up to 10 diffusing species. The original code had difficulty dealing with heteronuclear molecule formation such as HD and DT. That has been removed. Under pre-specified boundary enclosure conditions and solution-law dependent diffusion boundary conditions, such as Sieverts' law, TMAP7 automatically generates heteronuclear molecular partial pressures when solubilities and partial pressures of the homonuclear molecular species are provided for law-dependent diffusion boundary conditions. A further sophistication is the addition of non-diffusing surface species. Atoms such as oxygen or nitrogen or formation and decay or combination of hydroxyl radicals on metal surfaces are sometimes important in reactions with diffusing hydrogen isotopes but do not themselves diffuse appreciably in the material. TMAP7 will accommodate up to 30 such surface species, allowing the user to specify relationships between those surface concentrations and partial pressures of gaseous species above the surfaces or to form them dynamically by combining diffusion species or other surface species. Additionally, TMAP7 allows the user to include a surface binding energy and an adsorption barrier energy. The code includes asymmetrical diffusion between the surface

  13. Managing asbestos in Italy: twenty years after the ban.

    2012-01-01

    Establishing an asbestos ban is not sufficient to achieve effective primary prevention. Twenty years after the Italian asbestos ban, the residual presence of asbestos-containing materials, estimated to be 80 percent of the quantity existing in 1992, may still be the cause of negative effects to the health of workers and the general population. The so called "asbestos way-out" at this rate of cleaning up, roughly 1 percent per year, is too slow, and new policy to re-discuss the entire process is needed. Encouragement of the owners with tax relief when the substitution of the asbestos roofs is performed with photovoltaic panels, as well as reducing the cost of removal planning local landfills may be the keys to accelerate the cleanup process.

    Full Text Available This article explores some of the latest developments in the scholarship on race relations and nationalism that seek to address the impact of globalization and the changed geo-political relations of the first decade of the twenty-first century. New patterns of identification, some of which challenge existing group boundaries and others that reinforce them, can be seen to flow from the effects of global market changes and the political counter-movements against them. The impact of the “war on terrorism”, the limits of the utility of hard power, and the need for new mechanisms of inter-racial and inter-ethnic conflict resolution are evaluated to emphasize the complexity of these group relations in the new world disorder.

    The challenge of providing adequate power to enable world prosperity in the twenty-first century to continue was discussed. It was estimated that by 2050, a prosperous world of 10 billion people will require 60 TWt of thermal power. Conventional power systems will not be able to provide the needed energy because of limited fuels, contamination of the biosphere and costs. A viable, cost effective alternative will be solar energy that is captured in space and from facilities on the Moon, and that is imported to Earth by microwaves. Global electric power systems that use the Moon and deliver 1,000 TWe-Y of energy by 2070 was suggested as the most obvious alternative. Despite the huge initial cost of 20 to 100 trillion dollars, the long-term cost was said to be small compared to terrestrial and Earth-orbital options. 30 refs., 2 figs.

    The University of Mississippi and Mississippi State University are partnering with National Aeronautics and Space Administration (NASA) to develop a Research Projects Knowledge Base (RPKB) and a Partner Network Knowledge Base (PNKB) that will allow the user community to more easily locate the results of NASA funded research and be able to contact potential partners for future research. The RPKB and PNKB will also help NASA and the user community generate new topics for research projects that benefit society. The assessment of the needs of the user community for the RPKB and the PNKB was conducted through a combination of phone interviews with representatives of the user community, evaluations of existing data and tools currently employed by scientists, collaborations between NASA and the MRC, and the results of a November, 2006 workshop. This information was combined with an email survey, resulting in a report that describes how the users of the RPKB and the PNKB want to access the information in the knowledge bases, input new information into the RPKB and PNKB, and generate reports and diagrams, such as formulation reports. The compilation of the user's needs presented here is being used to design access and input tools for the user community. When fully developed the RPKB and the PNKB will use the NASA enterprise architecture modeling and viewing capability to provide NASA and the user community a more efficient way to identify potential research projects and partners.

    The Lower Hybrid Simulation Code (LSC) is a computational model of lower hybrid current drive in the presence of an electric field. Details of geometry, plasma profiles, and circuit equations are treated. Two-dimensional velocity space effects are approximated in a one-dimensional Fokker-Planck treatment. The LSC was originally written to be a module for lower hybrid current drive called by the Tokamak Simulation Code (TSC), which is a numerical model of an axisymmetric tokamak plasma and the associated control systems. The TSC simulates the time evolution of a free boundary plasma by solving the MHD equations on a rectangular computational grid. The MHD equations are coupled to the external circuits (representing poloidal field coils) through the boundary conditions. The code includes provisions for modeling the control system, external heating, and fusion heating. The LSC module can also be called by the TRANSP code. TRANSP represents the plasma with an axisymmetric, fixed-boundary model and focuses on calculation of plasma transport to determine transport coefficients from data on power inputs and parameters reached. This manual covers the basic material needed to use the LSC. If run in conjunction with TSC, the "TSC Users Manual" should be consulted. If run in conjunction with TRANSP, on-line documentation will be helpful. A theoretical background of the governing equations and numerical methods is given. Information on obtaining, compiling, and running the code is also provided.

    User recognition is examined using neural and conventional techniques for processing speech and face images. This article for the first time attempts to overcome this significant problem of distortions inherently captured over multiple sessions (days). Speaker recognition uses both Linear Predictive Coding (LPC) cepstral and auditory neural model representations with speaker dependent codebook designs. For facial imagery, recognition is developed on a neural network that consists of a single hidden layer multilayer perceptron backpropagation network using either the raw data as inputs or principal components of the raw data computed using the Karhunen-Loeve Transform as inputs. The data consists of 10 subjects; each subject recorded utterances and had images collected for 10 days. The utterances collected were 400 rich phonetic sentences (4 sec), 200 subject name recordings (3 sec), and 100 imposter name recordings (3 sec). Face data consists of over 2000, 32 X 32 pixel, 8 bit gray scale images of the 10 subjects. Each subsystem attains over 90% verification accuracy individually using test data gathered on days following the training data.

    The construction of seismological community services for the European Plate Observing System Research Infrastructure (EPOS) is by now well under way. A significant number of services are already operational, largely based on those existing at established institutions or collaborations like ORFEUS, EMSC, AHEAD and EFEHR, and more are being added to be ready for internal validation by late 2017. In this presentation we focus on a number of issues related to the interaction of the community of users with the services provided by the seismological part of the EPOS research infrastructure. How users interact with a service (and how satisfied they are with this interaction) is viewed as one important component of the validation of a service within EPOS, and certainly is key to the uptake of a service and from that also it's attributed value. Within EPOS Seismology, the following aspects of user interaction have already surfaced: - user identification (and potential tracking) versus ease-of-access and openness Requesting users to identify themselves when accessing a service provides various advantages to providers and users (e.g. quantifying & qualifying the service use, customization of services and interfaces, handling access rights and quotas), but may impact the ease of access and also shy away users who don't wish to be identified for whatever reason. - service availability versus cost There is a clear and prominent connection between the availability of a service, both regarding uptime and capacity, and its operational cost (IT systems and personnel), and it is often not clear where to draw the line (and based on which considerations). In connection to that, how to best utilize third-party IT infrastructures (either commercial or public), and what the long-term cost implications of that might be, is equally open. - licensing and attribution The issue of intellectual property and associated licensing policies for data, products and services is only recently gaining

    Within the framework of the 7th Framework European project FIELD_AC, SIMO and the LIM/UPC have undertaken a study about the operational oceanography requirements of a selected group of specific end-users in four different European coastal regions, namely Hamburg, Liverpool, Barcelona and Venice. The activities of all the target organisations are related to coastal issues, varying from aquaculture to marinas and port management, Water Framework Directive implementation, renewable energies and flooding alerts. Information has been compiled using a specific questionnaire that has been distributed to all potential users, in addition to workshops held in the four mentioned regions. A total number of 25 questionnaires have been collected in all the locations from a variety of users. Results have been analysed depending on the location but also considering the type of organisation. Information about the spatial and temporal resolution requirements, variables needed, locations to be considered, frequency of data delivery and formats requirements have been gathered. This input from the end-users is being used both in the FIELD_AC modelling set up and also in the development of an application to visualise the results. Regarding the latter, all the modelling results and observational data will be handled using a THREDDS catalogue linked to a web-based GIS application.

    1997-01-01

    This paper presents techniques to verify the identity of computer users using the keystroke dynamics of computer user's login string as characteristic patterns using pattern recognition and neural network techniques. This work is a continuation of our previous work where only interkey times were used as features for identifying computer users. In this work we used the key hold times for classification and then compared the performance with the former interkey time-based technique. Then we use the combined interkey and hold times for the identification process. We applied several neural network and pattern recognition algorithms for verifying computer users as they type their password phrases. It was found that hold times are more effective than interkey times and the best identification performance was achieved by using both time measurements. An identification accuracy of 100% was achieved when the combined hold and intekey time-based approach were considered as features using the fuzzy ARTMAP, radial basis function networks (RBFN), and learning vector quantization (LVQ) neural network paradigms. Other neural network and classical pattern algorithms such as backpropagation with a sigmoid transfer function (BP, Sigm), hybrid sum-of-products (HSOP), sum-of-products (SOP), potential function and Bayes' rule algorithms gave moderate performance.

  6. Temporal feature perception in cochlear implant users.

    Directory of Open Access Journals (Sweden)

    Lydia Timm

    Full Text Available For the perception of timbre of a musical instrument, the attack time is known to hold crucial information. The first 50 to 150 ms of sound onset reflect the excitation mechanism, which generates the sound. Since auditory processing and music perception in particular are known to be hampered in cochlear implant (CI users, we conducted an electroencephalography (EEG study with an oddball paradigm to evaluate the processing of small differences in musical sound onset. The first 60 ms of a cornet sound were manipulated in order to examine whether these differences are detected by CI users and normal-hearing controls (NH controls, as revealed by auditory evoked potentials (AEPs. Our analysis focused on the N1 as an exogenous component known to reflect physical stimuli properties as well as on the P2 and the Mismatch Negativity (MMN. Our results revealed different N1 latencies as well as P2 amplitudes and latencies for the onset manipulations in both groups. An MMN could be elicited only in the NH control group. Together with additional findings that suggest an impact of musical training on CI users' AEPs, our findings support the view that impaired timbre perception in CI users is at partly due to altered sound onset feature detection.

    Full Text Available This article is based on a study of an educational and developmental programme, in which the task-centred coping approach (TCCA was a central part. Twenty social worker practitioners from Norwegian municipal social services (MSS participated in the programme, and practiced TCCA with 74 of their service users. The aim of the study was to develop knowledge about how service users evolve their housing competence by utilizing TCCA.The study was based on a way of participatory action research, in which the researcher was positioned as a partly participating researcher. The researcher tried to attain knowledge from the individualized activities of the service users and the practitioners, and use this knowledge as a contribution to developing their practice and the programme. User participation was one of the cornerstones of the study, and individualization meant matching the approaches of the practitioners to the experienced needs of the individual service user.

    The original SIMION was an electrostatic lens analysis and design program developed by D.C. McGilvery at Latrobe University, Bundoora Victoria, Australia, 1977. SIMION for the PC, developed at the Idaho National Engineering Laboratory, shares little more than its name with the original McGilvery version. INEL`s fifth major SIMION release, version 6.0, represents a quantum improvement over previous versions. This C based program can model complex problems using an ion optics workbench that can hold up to 200 2D and/or 3D electrostatic/magnetic potential arrays. Arrays can have up to 10,000,000 points. SIMION 3D`s 32 bit virtual Graphics User Interface provides a highly interactive advanced user environment. All potential arrays are visualized as 3D objects that the user can cut away to inspect ion trajectories and potential energy surfaces. User programs have been greatly extended in versatility and power. A new geometry file option supports the definition of highly complex array geometry. Extensive algorithm modifications have dramatically improved this version`s computational speed and accuracy.

Traj_opt loosely couples the Ames three-degrees-of-freedom trajectory package Traj (see NASA-TM-2004-212847) with the SNOPT optimization package (Stanford University Technical Report SOL 98-1). Traj_opt version January 22, 2003 is covered by this user guide. The program has been applied extensively to entry and ascent abort trajectory calculations for sharp and blunt crew transfer vehicles. The main optimization variables are control points for the angle of attack and bank angle time histories. No propulsion options are provided, but numerous objective functions may be specified and the nonlinear constraints implemented include a distributed surface heating constraint capability. Aero-capture calculations are also treated with an option to minimize orbital eccentricity at apoapsis. Traj_opt runs efficiently on a single processor, using forward or central differences for the gradient calculations. Results may be displayed conveniently with Gnuplot scripts. Control files recommended for five standard reentry and ascent abort trajectories are included along with detailed descriptions of the inputs and outputs.

    Mário Terra Filho

    Full Text Available CONTEXT: Brazilian researchers have recently recognized a marked increase in the number of people using abusable drugs and the consequences of this habit. It has become a major public health problem in a potentially productive segment of the general population. In the last few years, several medical articles have given special emphasis to pulmonary complications related to cocaine use. This review is based on this information and experience acquired with groups of cocaine users. OBJECTIVE: To present to physicians the pulmonary aspects of cocaine use and warn about the various effects this drug has on the respiratory system, stressing those related to long-term use. DESIGN: Narrative review. METHOD: Pulmonary complications are described. These may include infections (Staphylococcus aureus, pulmonary tuberculosis, acquired immunodeficiency syndrome/aids, etc., aspiration pneumonia, lung abscess, empyema, septic embolism, non-cardiogenic pulmonary edema, barotrauma, pulmonary granulomatosis, bronchiolitis obliterans and organizing pneumonia, pneumonitis and interstitial fibrosis, pneumonitis hypersensitivity, lung infiltrates and eosinophilia in individuals with bronchial hyperreactivity, diffuse alveolar hemorrhage, vasculitis, pulmonary infarction, pulmonary hypertension and alterations in gas exchange. It is concluded that physicians should give special attention to the various pulmonary and clinical manifestations related to cocaine use, particularly in young patients.

    2008-10-15

    This report summarizes the methodology and results of a user perspectives study conducted by the Community Driven Improvement of Globus Software (CDIGS) project. The purpose of the study was to document the work-related goals and challenges facing today's scientific technology users, to record their perspectives on Globus software and the distributed-computing ecosystem, and to provide recommendations to the Globus community based on the observations. Globus is a set of open source software components intended to provide a framework for collaborative computational science activities. Rather than attempting to characterize all users or potential users of Globus software, our strategy has been to speak in detail with a small group of individuals in the scientific community whose work appears to be the kind that could benefit from Globus software, learn as much as possible about their work goals and the challenges they face, and describe what we found. The result is a set of statements about specific individuals experiences. We do not claim that these are representative of a potential user community, but we do claim to have found commonalities and differences among the interviewees that may be reflected in the user community as a whole. We present these as a series of hypotheses that can be tested by subsequent studies, and we offer recommendations to Globus developers based on the assumption that these hypotheses are representative. Specifically, we conducted interviews with thirty technology users in the scientific community. We included both people who have used Globus software and those who have not. We made a point of including individuals who represent a variety of roles in scientific projects, for example, scientists, software developers, engineers, and infrastructure providers. The following material is included in this report: (1) A summary of the reported work-related goals, significant issues, and points of satisfaction with the use of Globus software

While the scientific understanding of teaching/learning process is shifting, changes also affect the methods of user training in libraries.Human-computer interaction (HCI is an interdisciplinary and a very active research area which studies how humans use computers - their mental and behavioral characteristics. The application of psychological theories to HCI are especially great on three areas: psychological (mental, conceptual models, individual differences, and error behavior.The mental models theory is powerful tool for understanding the ways in which users interact with an information system. Claims, based on this theory can affect the methods (conceptualization of user training and the overall design of information systems.

    20 years ago, in the summer of 1989, an office was created to assist the thousands of users who come to CERN each year, working over the broad range of projects and collaborations. Chris Onions (right), head of the Users’ Office, with Bryan Pattison (left), the Office’s founder.Before the inception of the Users Office, it was common for users to spend at least an entire day moving from office to office in search of necessary documentation and information in order to make their stay official. "Though the Office has undergone various changes throughout its lifetime, it has persisted in being a welcoming bridge to facilitate the installation of visitors coming from all over the world", says Chris Onions, head of the Users Office. This September, the Office will celebrate its 20-year anniversary with a drink offered to representatives of the User community, the CERN management and staff members from the services with whom the Office is involved. &...

  18. User Involvement And Entrepreneurial Action

    2007-01-01

    Full Text Available Involving users in the innovation process is a subject of much research, experimentation, and debate. Less attention has been given to the limits to user involvement that ensue from specific organizational characteristics. This article explores barriers to the utilization of users’ input in two small companies developing interactive digital applications. We contrast our findings to earlier research involving large companies to identify features of entrepreneurial sensemaking and action that influence the utilization of users’ input. We find that the small companies follow a distinct action rationality, leading to rapid implementation of some user inputs, and defensiveness toward others. Both sets of data also reveal common features that are often overlooked in the literature. We reconceptualize user involvement as a form of interaction between users and innovating companies that is facilitated and constrained by micro-sociological processes, on the one hand, and the nature of the competitive environment, on the other.

    Full Text Available Twenty-six of the agricultural universities in India teach user education and information literacy (IL. This article evaluates these courses and investigates if and how the course curriculum blends research and technical writing skills effectively. Unfortunately, the courses lack uniformity in teaching IL and technical writing skills. Since the universities are under state government control, they are unable to provide uniform curricula throughout India. There is also a need for a credited course on IL, integrating ICT and computer skills, and another course for research and technical writing.

    Identifying online user reputation based on the rating information of the user-object bipartite networks is important for understanding online user collective behaviors. Based on the Bayesian analysis, we present a parameter-free algorithm for ranking online user reputation, where the user reputation is calculated based on the probability that their ratings are consistent with the main part of all user opinions. The experimental results show that the AUC values of the presented algorithm could reach 0.8929 and 0.8483 for the MovieLens and Netflix data sets, respectively, which is better than the results generated by the CR and IARR methods. Furthermore, the experimental results for different user groups indicate that the presented algorithm outperforms the iterative ranking methods in both ranking accuracy and computation complexity. Moreover, the results for the synthetic networks show that the computation complexity of the presented algorithm is a linear function of the network size, which suggests that the presented algorithm is very effective and efficient for the large scale dynamic online systems.

  2. Audit result and its users

    2014-01-01

    Full Text Available The article identifies essence of the “audit result” and “users of audit result” notions and characteristics of the key audit results user. It shows that in order to give a wide characteristic of users it is expedient to unite all objects, which could be used (audit report, fact of refusal to conduct audit and information that is submitted to managers in the process of audit with the term “audit result” and classify it depending on the terms of submission by final and intermediate result. The article offers to define audit results user as a person, persons or category of persons for whom the auditor prepares the audit report and, in cases, envisaged by international standards of the audit and domestic legislative and regulatory acts, provides other additional information concerning audit issues. In order to identify the key audit results user the article distributes all audit tasks into two groups depending on possibilities of identification of users. The article proves that the key user should be identified especially in cases of a mandatory audit and this process should go in interconnection with the mechanism of allocation of a key user of financial reports. It offers to consider external users with direct financial interests, who cannot request economic subjects directly to provide information and who should rely on general financial reports and audit report when receiving significant portion of information they need, as the key user. The article makes proposals on specification of the categorical mechanism in the sphere of audit, which are the basis for audit quality assessment, identification of possibilities and conditions of appearance of the necessary and sufficient trust to the auditor opinion.

  3. Peak experiences of psilocybin users and non-users.

    2013-01-01

    Maslow (1970) defined peak experiences as the most wonderful experiences of a person's life, which may include a sense of awe, well-being, or transcendence. Furthermore, recent research has suggested that psilocybin can produce experiences subjectively rated as uniquely meaningful and significant (Griffiths et al. 2006). It is therefore possible that psilocybin may facilitate or change the nature of peak experiences in users compared to non-users. This study was designed to compare the peak experiences of psilocybin users and non-users, to evaluate the frequency of peak experiences while under the influence of psilocybin, and to assess the perceived degree of alteration of consciousness during these experiences. Participants were recruited through convenience and snowball sampling from undergraduate classes and at a musical event. Participants were divided into three groups, those who reported a peak experience while under the influence of psilocybin (psilocybin peak experience: PPE), participants who had used psilocybin but reported their peak experiences did not occur while they were under the influence of psilocybin (non-psilocybin peak experience: NPPE), and participants who had never used psilocybin (non-user: NU). A total of 101 participants were asked to think about their peak experiences and complete a measure evaluating the degree of alteration of consciousness during that experience. Results indicated that 47% of psilocybin users reported their peak experience occurred while using psilocybin. In addition, there were significant differences among the three groups on all dimensions of alteration of consciousness. Future research is necessary to identify factors that influence the peak experiences of psilocybin users in naturalistic settings and contribute to the different characteristics of peak experiences of psilocybin users and non-users.

    This book explores the design process for user experience and engagement, which expands the traditional concept of usability and utility in design to include aesthetics, fun and excitement. User experience has evolved as a new area of Human Computer Interaction research, motivated by non-work oriented applications such as games, education and emerging interactive Web 2.0. The chapter starts by examining the phenomena of user engagement and experience and setting them in the perspective of cognitive psychology, in particular motivation, emotion and mood. The perspective of aesthetics is expande

    errors can cause significant losses, even loss of life. Hence, end users are best served when they have performance information relevant to their needs, this paper’s focus. Relative class size (rCS is commonly recognized as a confounding factor in CPD evaluation. Unfortunately, rCS-invariant measures are not easily mapped to end user conditions. We determine a cause of rCS invariance, joint probability table (JPT normalization. JPT normalization means that more end user efficacious measures can be used without sacrificing invariance. An important revelation is that without data normalization, the Matthews correlation coefficient (MCC and information coefficient (IC are not relative class size invariants; this is a potential source of confusion, as we found not all reports using MCC or IC normalize their data. We derive MCC rCS-invariant expression. JPT normalization can be extended to allow JPT rCS to be set to any desired value (JPT tuning. This makes sensitivity analysis feasible, a benefit to both applied researchers and practitioners (end users. We apply our findings to two published CPD studies to illustrate how end users benefit.

  10. User requirements for satellite snow data service

    Kolberg, S.; Standley, A.; Hiltbrunner, D.; Hallikainen, M.

    1997-12-31

    This report discusses the answers given by ten users or potential users of remotely sensed snow data when asked about their data needs and present measurements, their requirements for remote sensing data and potential of using such, and the models or other analysis tools in which the information is used. The answers show both consensus and differences among the respondents` use of snow data and requirements for remote sensing snow products. For water resources planning and management, the most important variable is snow water equivalent, with acceptable errors around 10%. Acceptable spatial error is typically in the range of 200 m to 1 km. For flood forecasting and short-term runoff simulation, snow covered area is more important, with a classification of 5 to 8 steps being generally sufficient. Meteorologists tend to focus on albedo and snow coverage data, with 5% steps desired for albedo. Geometric resolution and accuracy is less important, temporal resolution and delivery time is more important than in water resource management. For avalanche use, most snow variables except water equivalent are important, several in depth profiles. Spatial and temporal requirements are high. In all user groups there is a desire for models which can use measured values quantitatively. Today, measured snow information is largely interpreted manually and subjectively and lead to actions based on experience and judgement. The organizing of measurements, simulations and calibrated sub-models with varying uncertainty levels is partly a conceptual problem, partly a software problem. 1 ref.

    1996-12-31

    The historical development of the civil nuclear power generation industry is examined in the light of the need to meet conflicting energy-supply and environmental pressures over recent decades. It is suggested that fission (thermal and fast) reactors will dominate the market up to the period 2010-2030, with fusion being relegated to the latter part of the twenty-first century. A number of issues affecting the use of nuclear electricity generation in Western Europe are considered including its cost, industrial strategy needs, and the public acceptability of nuclear power. The contribution of nuclear power stations to achieving CO2 targets aimed at relieving global warming is discussed in the context of alternative strategies for sustainable development, including renewable energy sources and energy-efficiency measures. Trends in the generation of nuclear electricity from fission reactors are finally considered in terms of the main geopolitical groupings that make up the world in the mid-1990s. Several recent, but somewhat conflicting, forecasts of the role of nuclear power in the fuel mix to about 2020 are reviewed. It is argued that the only major expansion in generating capacity will take place on the Asia-Pacific Rim and not in the developing countries generally. Nevertheless, the global nuclear industry overall will continue to be dominated by a small number of large nuclear electricity generating countries; principally the USA, France and Japan. (UK).

    2010-01-01

    We obtained time-series radial velocity spectroscopy of twenty cataclysmic variable stars, with the aim of determining orbital periods P_orb. All of the stars reported here prove to have P_orb > 3.5 h. For sixteen of the stars, these are the first available period determinations, and for the remaining four (V709 Cas, AF Cam, V1062 Tau, and RX J2133+51) we use new observations to improve the accuracy of previously-published periods. Most of the targets are dwarf novae, without notable idiosyncracies. Of the remainder, three (V709 Cas, V1062 Tau, and RX J2133+51) are intermediate polars (DQ Her stars); one (IPHAS 0345) is a secondary-dominated system without known outbursts, similar to LY UMa; one (V1059 Sgr) is an old nova; and two others (V478 Her and V1082 Sgr) are long-period novalike variables. The stars with new periods are IPHAS 0345 (0.314 d); V344 Ori (0.234 d); VZ Sex (0.149 d); NSVS 1057+09 (0.376 d); V478 Her (0.629 d); V1059 Sgr (0.286 d); V1082 Sgr (0.868 d); FO Aql (0.217 d); V587 Lyr (0.275 d); ...

  13. New Bachelards?: Reveries, Elements and Twenty-First Century Materialisms

    Directory of Open Access Journals (Sweden)

    James L. Smith

    2012-10-01

    Full Text Available Recent years have seen an infusion of new ideas into material philosophy through the work of the so-called ‘new materialists’. Poignant examples appear within two recent books: the first, Vibrant Matter by Jane Bennett (2010, sets out to “enhance receptivity to the impersonal life that surrounds and infuses us” (2010: 4. The second, Elemental Philosophy by David Macauley (2010, advocates an anamnesis or recollection of the elements as imaginatively dynamic matter. Within his essays on the imagination of matter, Gaston Bachelard outlined an archetypal vision of the elements predicated upon the material imagination. He explored the manner in which the imagination inhabits the world, is triggered by the stimulus of material dynamism, and is formed from a co-constitution of subject and object. This article proposes that recent trends in materialist philosophy – as exemplified by the monographs of Bennett and Macauley – reinforce the ideas of Bachelard and take them in new directions. Bachelard provides us with a compelling argument for the rediscovery of material imagination, whereas New Materialism portrays a vision of matter filled with autonomous dynamism that lends itself to entering into a relationship with this imagination. Consequently, this article proposes that Gaston Bachelard has gained a new relevance as a result of contemporary trends in material philosophy, has taken on new possibilities through recent scholarship, and remains a force within the twenty-first century discursive landscape.

    2016-12-01

    Full Text Available Objective: Sarcoidosis is a multisystemic disease, exact cause of disease is unknown but it is assumed that genetic predisposition and ethnic factors play a role in etiology. Studies related with familial sarcoidosis is limited and only case reports about familial sarcoidosis is available from our country. We aimed to evaluate the prevelance of familial sarcoidosis and clinical findings of cases with familial sarcoidosis. Methods: We retrospectively documented file records of 678 patients diagnosed with sarcoidosis and followed up in outpatient clinic of sarcoidosis from January 1996 to February 2016. 28 familial sarcoidosis cases in 14 families were enrolled into the study. Their demographic findings, family relationship, symptoms, laboratory and pulmonary function test results, radiological apperances, diagnostic methods, treatments were recorded. Results: Twenty-eight sarcoidosis patients out of 678 reported as familial cases, giving a prevelance of familial sarcoidosis as 4%. There were 8 sarcoidosis sib, 4 sarcoidosis mother-child, 1 sarcoidosis father-child and 1 sarcoidosis cousin relationship. Female/male ratio was 1.8, mean age of the study population was 43, most freguent symptoms were cough and dyspnea, stage 2 was mostly seen according to chest X-ray, most common CT appearance was mediastinal lymphadenopathy and mediastinoscopy was the most freguent diagnostic method. Conclusion: This study is important to lead interrogation of family in patients with suspected sarcoidosis and future studies investigating familial aggregation in sarcoidosis.

    We report precise measures of the orbital and superhump period in twenty more dwarf novae. For ten stars, we report new and confirmed spectroscopic periods - signifying the orbital period P_o - as well as the superhump period P_sh. These are GX Cas, HO Del, HS Vir, BC UMa, RZ Leo, KV Dra, KS UMa, TU Crt, QW Ser, and RZ Sge. For the remaining ten, we report a medley of P_o and P_sh measurements from photometry; most are new, with some confirmations of previous values. These are KV And, LL And, WX Cet, MM Hya, AO Oct, V2051 Oph, NY Ser, KK Tel, HV Vir, and RX J1155.4-5641. Periods, as usual, can be measured to high accuracy, and these are of special interest since they carry dynamical information about the binary. We still have not quite learned how to read the music, but a few things are clear. The fractional superhump excess epsilon [=(P_sh-P_o)/P_o] varies smoothly with P_o. The scatter of the points about that smooth curve is quite low, and can be used to limit the intrinsic scatter in M_1, the white dwarf ...

    2003-06-30

    The purpose of the Twenty Second Fungal Genetics Conference is to bring together scientists and students who are interested in genetic approaches to studying the biology of filamentous fungi. It is intended to stimulate thinking and discussion in an atmosphere that supports interactions between scientists at different levels and in different disciplines. Topics range from the basic to the applied. Filamentous fungi impact human affairs in many ways. In the environment they are the most important agents of decay and nutrient turnover. They are used extensively in the food industry for the production of food enzymes such as pectinase and food additives such as citric acid. They are used in the production of fermented foods such as alcoholic drinks, bread, cheese, and soy sauce. More than a dozen species of mushrooms are used as foods directly. Many of our most important antibiotics, such as penicillin, cyclosporin, and lovastatin, come from fungi. Fungi also have many negative impacts on human health and economics. Fungi are serious pathogens in immuno-compromised patients. Fungi are the single largest group of plant pathogens and thus a serious limit on crop productivity throughout the world. Many fungi are allergenic, and mold contamination of residences and commercial buildings is now recognized as a serious public health threat. As decomposers, fungi cause extensive damage to just about all natural and synthetic materials.

  17. Twenty years on: Poverty and hardship in urban Fiji

    Jenny Bryant-Tokalau

    2012-09-01

    Full Text Available Through ‘official statistics’, academic and donor interpretations as well as the eyes of Suva residents, this paper presents an overview and case study of twenty years of growing poverty and hardship in the contemporary Pacific. Focusing on the past two decades, the paper notes how much, and yet so little, has changed for those attempting to make a living in the rapidly developing towns and cities. Changing interpretations of poverty and hardship are presented, moving from the ‘no such thing’ view, to simplification, and finally to an understanding that Pacific island countries, especially Fiji, are no longer an ‘extension’ of Australia and New Zealand, but independent nations actively trying to find solutions to their issues of economic, social and political hardship whilst facing challenges to traditional institutions and networks. Fiji is in some respects a very particular case as almost half of the population has limited access to secure land, but the very nature of that vulnerability to hardship and poverty holds useful lessons for wider analysis.

  18. Pressure effects on regional mean sea level trends in the German Bight in the twenty-first century

    Albrecht, Frauke; Weisse, Ralf

    2014-05-01

    The effect of large-scale atmospheric pressure changes on regional mean sea level projections in the German Bight in the twenty-first century are considered. A developed statistical model is applied to climate model data of sea level pressure for the twenty-first century to assess the potential contribution of large-scale atmospheric changes to future sea level changes in the German Bight. Using 78 experiments, an ensemble mean of 1.4-cm rise in regional mean sea level is estimated until the end of the twenty-first century. Changes are somewhat higher for realisations of the special report on emission scenarios (SRES) A1B and A2, but generally do not exceed a few centimeters. This is considerably smaller than the changes expected from steric and self-gravitational effects. Large-scale changes in sea level pressure are thus not expected to provide a substantial contribution to twenty-first century sea level changes in the German Bight.

    Klett, T.R.; Charpentier, Ronald R.

    2003-01-01

    The USGS FORSPAN model is designed for the assessment of continuous accumulations of crude oil, natural gas, and natural gas liquids (collectively called petroleum). Continuous (also called ?unconventional?) accumulations have large spatial dimensions and lack well defined down-dip petroleum/water contacts. Oil and natural gas therefore are not localized by buoyancy in water in these accumulations. Continuous accumulations include ?tight gas reservoirs,? coalbed gas, oil and gas in shale, oil and gas in chalk, and shallow biogenic gas. The FORSPAN model treats a continuous accumulation as a collection of petroleumcontaining cells for assessment purposes. Each cell is capable of producing oil or gas, but the cells may vary significantly from one another in their production (and thus economic) characteristics. The potential additions to reserves from continuous petroleum resources are calculated by statistically combining probability distributions of the estimated number of untested cells having the potential for additions to reserves with the estimated volume of oil and natural gas that each of the untested cells may potentially produce (total recovery). One such statistical method for combination of number of cells with total recovery, used by the USGS, is called ACCESS.

    Every second, the thoughts and feelings of millions of people across the world are recorded in the form of 140-character tweets using Twitter. However, despite the enormous potential presented by this remarkable data source, we still do not have an understanding of the Twitter population itself......: Who are the Twitter users? How representative of the overall population are they? In this paper, we take the first steps towards answering these questions by analyzing data on a set of Twitter users representing over 1% of the U.S. population. We develop techniques that allow us to compare the Twitter...... population to the U.S. population along three axes (geography, gender, and race/ethnicity), and find that the Twitter population is a highly non-uniform sample of the population....

  1. Users guide for information retrieval using APL

    Science.gov (United States)

    Shapiro, A.

    1974-01-01

    A Programming Language (APL) is a precise, concise, and powerful computer programming language. Several features make APL useful to managers and other potential computer users. APL is interactive; therefore, the user can communicate with his program or data base in near real-time. This, coupled with the fact that APL has excellent debugging features, reduces program checkout time to minutes or hours rather than days or months. Of particular importance is the fact that APL can be utilized as a management science tool using such techniques as operations research, statistical analysis, and forecasting. The gap between the scientist and the manager could be narrowed by showing how APL can be used to do what the scientists and the manager each need to do, retrieve information. Sometimes, the information needs to be retrieved rapidly. In this case APL is ideally suited for this challenge.

  2. A nonlinear, implicit, three-dimensional finite element code for solid and structural mechanics - User`s Manual

    Energy Technology Data Exchange (ETDEWEB)

    Maker, B.N.

    1995-04-14

    This report provides a user`s manual for NIKE3D, a fully implicit three-dimensional finite element code for analyzing the finite strain static and dynamic response of inelastic solids, shells, and beams. Spatial discretization is achieved by the use of 8-node solid elements, 2-node truss and beam elements, and 4-node membrane and shell elements. Over twenty constitutive models are available for representing a wide range of elastic, plastic, viscous, and thermally dependent material behavior. Contact-impact algorithms permit gaps, frictional sliding, and mesh discontinuities along material interfaces. Several nonlinear solution strategies are available, including Full-, Modified-, and Quasi-Newton methods. The resulting system of simultaneous linear equations is either solved iteratively by an element-by-element method, or directly by a factorization method, for which case bandwidth minimization is optional. Data may be stored either in or out of core memory to allow for large analyses.

    In this study we investigated safety-related usability issues of an advanced medical technology, a radiosurgery system. We were interested in which criteria are important for users when a system's usability and safety is to be improved. The data collection was based on interviews and observations at three different sites where the Leksell GammaKnife is used. The analysis was qualitative. The main finding was that the user's identity or professional background has a significant impact both on how he or she views his or her role in the clinical setting, and on how he or she defines what improvements are necessary and general safety issues. In fact, the opinion even of users experienced in safety-related problems was highly influenced by how they related to the technology and its development. None of the users actually considered Leksell GammaKnife as lacking in safety, instead, their assessment was directed towards potential future system improvements. Our findings suggest that the importance of user identity or professional background cannot be neglected during the development of advanced technology. They also suggest that the user feedback should always be related to user background and identity in order to understand how important different issues are for particular users.

  4. Energy Efficiency of D2D Multi-User Cooperation.

    2017-03-28

    The Device-to-Device (D2D) communication system is an important part of heterogeneous networks. It has great potential to improve spectrum efficiency, throughput and energy efficiency cooperation of multiple D2D users with the advantage of direct communication. When cooperating, D2D users expend extraordinary energy to relay data to other D2D users. Hence, the remaining energy of D2D users determines the life of the system. This paper proposes a cooperation scheme for multiple D2D users who reuse the orthogonal spectrum and are interested in the same data by aiming to solve the energy problem of D2D users. Considering both energy availability and the Signal to Noise Ratio (SNR) of each D2D user, the Kuhn-Munkres algorithm is introduced in the cooperation scheme to solve relay selection problems. Thus, the cooperation issue is transformed into a maximum weighted matching (MWM) problem. In order to enhance energy efficiency without the deterioration of Quality of Service (QoS), the link outage probability is derived according to the Shannon Equation by considering the data rate and delay. The simulation studies the relationships among the number of cooperative users, the length of shared data, the number of data packets and energy efficiency.

    To determine whether post-menopausal women with a history of bisphosphonate use are at greater risk for implant failure or osteonecrosis of the jaw (ONJ) than an age- and gender-matched population with no history of bisphosphonate use. A retrospective chart review and phone interview was conducted of patients seen at the Mayo Clinic who had implants placed after November 2006. Bisphosphonate users were identified by medical chart review. Dental implant survival and ONJ incidence were determined in a total of 82 post-menopausal non-bisphosphonate users and 55 post-menopausal bisphosphonate users using a phone interview. Implant failures were recorded and survival percentages were calculated for comparison. ONJ was not observed consequent to implant placement in any of the bisphosphonate users or non-users. In non-users, 163 out of 166 implants were surviving for a cumulative survival rate of 98.19%. In bisphosphonate users, 120 out of 121 implants were surviving for a cumulative survival rate of 99.17%. Dental implants placed in post-menopausal women have the same survival potential regardless of whether patients have a history of bisphosphonate use. Bisphosphonate users who undergo dental implant surgery are at low risk for osteonecrosis of the jaw and a bisphosphonate "drug holiday" is not indicated in these patients.

    2015-10-01

    Listening to music is still one of the more challenging aspects of using a cochlear implant (CI) for most users. Simple musical structures, a clear rhythm/beat, and lyrics that are easy to follow are among the top factors contributing to music appreciation for CI users. Modifying the audio mix of complex music potentially improves music enjoyment in CI users. A stereo music preprocessing scheme is described in which vocals, drums, and bass are emphasized based on the representation of the harmonic and the percussive components in the input spectrogram, combined with the spatial allocation of instruments in typical stereo recordings. The scheme is assessed with postlingually deafened CI subjects (N = 7) using pop/rock music excerpts with different complexity levels. The scheme is capable of modifying relative instrument level settings, with the aim of improving music appreciation in CI users, and allows individual preference adjustments. The assessment with CI subjects confirms the preference for more emphasis on vocals, drums, and bass as offered by the preprocessing scheme, especially for songs with higher complexity. The stereo music preprocessing scheme has the potential to improve music enjoyment in CI users by modifying the audio mix in widespread (stereo) music recordings. Since music enjoyment in CI users is generally poor, this scheme can assist the music listening experience of CI users as a training or rehabilitation tool.

  12. CAPTCHA: Impact on User Experience of Users with Learning Disabilities

    2016-12-01

    Full Text Available CAPTCHA is one of the most common solutions to check if the user trying to enter a Website is a real person or an automated piece of software. This challenge-response test, implemented in many Internet Websites, emphasizes the gaps between accessibility and security on the Internet, as it poses an obstacle for the learning-impaired in the reading and comprehension of what is presented in the test. Various types of CAPTCHA tests have been developed in order to address accessibility and security issues. The objective of this study is to investigate how the differences between various CAPTCHA tests affect user experience among populations with and without learning disabilities. A questionnaire accompanied by experiencing five different tests was administered to 212 users, 60 of them with learning disabilities. Response rates for each test and levels of success were collected automatically. Findings suggest that users with learning disabilities have more difficulties in solving the tests, especially those with distorted texts, have more negative attitudes towards the CAPTCHA tests, but the response time has no statistical difference from users without learning disabilities. These insights can help to develop and implement solutions suitable for many users and especially for population with learning disabilities.

    Full Text Available Objective: To assess the knowledge and satisfaction of users of a Basic Health Unit about the strategy of embracement. Methods: Descriptive study with qualitative approach, carried out in a Basic Health Unit, Fortaleza, Brazil, where practical activities of the Education Program of Work for Health of the University of Fortaleza were performed. Fifty eight service users were involved, following inclusion criteria: being present during the data collection, age over 18, regardless of sex, and voluntary participation. Data collection occurred in December 2009, through semi-structured interview. The data associated with the identification of users were processed in Microsoft Office Excel 2007, being organizedstatistically in table. Data related to qualitative aspects were analyzed according to the technique of content analysis. Results: 56 (97% were women, with ages ranging between 21 and 40 years, 34 (59% were married and 53 (91% are literate. On family income, 55 (95%received less than two minimum salaries per month. In order to facilitate understanding the speech of users, these were evaluated from the perspective of two categories: knowledge about embracement and satisfaction with embracement. Conclusion: Users have a limited view of the significance and magnitude of the embracement to provide the care. Although satisfied with the service, respondents report as negative aspects: the shortage of professionals, the professional relationship with user impaired due to constant delays of the professional, and the dehumanization of care.

    This driving simulator study extended knowledge on user experience using a strategy to mitigate distraction resulting from the use of in-vehicle information systems (IVISs). It examined the impact of system restrictions on users' needs, emotions and consequences of users' experience in terms of psychological reactance. In a repeated measures design, we asked 53 participants to perform secondary tasks with an IVIS while driving. Three versions of the system varied with respect to the number of operable functionalities. The more functionalities that were disabled while driving, the more negatively users rated the systems. Multilevel regression analyses of at least n = 155 data points revealed that drivers' need fulfilment predicted their emotions. Reactance depended on users' need fulfilment and emotions. Experienced autonomy mediated the relation between functional limitations and reactance. When developing interactive systems, one should focus on needs and be aware of potential unwanted consequences such as psychological reactance. Practitioner Summary: This driving simulator study highlights the importance of considering need fulfilment and users' emotions when developing an interactive system that provides high user experience. System restrictions could have negative consequences as users might show psychological reactance.

    Full Text Available This article analyzes the mechanism of stereotyping as exemplified by gender stereotypes of road users. Gender stereotypes are not only viewed as an a priori image of a percept, but also examined ‘in action’ — at the very moment of their actualization with road users. In the paper we have identified the content of road users’ gender stereotypes; analyzed the behaviour of male and female drivers, pinpointing a number of gender-specific behavioural features; demonstrated that male and female driving differ from each other in terms of speed, intensity and roughness; and identified the conditions and mechanisms underlying the actualization of gender stereotypes. Based on video and audio materials, we have found that drivers’ gender-specific behavioural features are perceivable to road users: such features trigger the actualization of gender stereotypes as attributive schemes, which determine the interaction between road users, while also laying the foundation for gender stereotypes.

    This book presents an alternative approach to studying smartphone-app user notifications. It starts with insights into user acceptance of mobile notifications in order to provide tools to support users in managing these. It extends previous research by investigating factors that influence users’ perception of notifications and proposes tools addressing the shortcomings of current systems. It presents a technical framework and testbed as an approach for evaluating the usage of mobile applications and notifications, and then discusses a series of studies based on this framework that investigate factors influencing users’ perceptions of mobile notifications. Lastly, a set of design guidelines for the usage of mobile notifications is derived that can be employed to support users in handling notifications on smartphones.

    2009-05-01

    Home visits have become increasingly widespread in Brazil since the emergence of the Family Health Program. The present study deals with users' perceptions of these visits, focusing on comprehensiveness and humanization of care. The study was exploratory and qualitative. Twenty-one interviews were performed with users from the six administrative health districts of Fortaleza, capital of Ceará State, Brazil. Analysis of the interviews revealed the existence of three core themes: (1) health professional-user relationships, i.e. users' perceptions of completeness and humanization of care during visits; (2) characterization of visits, with emphasis on operational aspects; and (3) user-health facility interaction, focusing on integration with other service. This theme was divided into three items: health facility management, equity, and integration of care. In conclusion, the study suggests that home visiting practices can be improved by enhancing the aspects of intersubjectivity, dialogue, and negotiation between health professionals, users, and the community.

    Full Text Available Abstract Background Little is known about users of electronic cigarettes, or their opinions, satisfaction or how and why they use such products. Methods An internet survey of 81 ever-users of ecigarettes in 2009. Participants answered open-ended questions on use of, and opinions about, ecigarettes. Results Respondents (73 current and 8 former users lived in France, Canada, Belgium or Switzerland. Most respondents (77% were men; 63% were former smokers and 37% were current smokers. They had used e-cigarettes for 100 days (median and drew 175 puffs per day (median. Participants used the ecigarette either to quit smoking (53 comments, to reduce their cigarette consumption (14 comments, in order not to disturb other people with smoke (20 comments, or in smoke-free places (21 comments. Positive effects reported with ecigarettes included their usefulness to quit smoking, and the benefits of abstinence from smoking (less coughing, improved breathing, better physical fitness. Respondents also enjoyed the flavour of ecigarettes and the sensation of inhalation. Side effects included dryness of the mouth and throat. Respondents complained about the frequent technical failures of ecigarettes and had some concerns about the possible toxicity of the devices and about their future legal status. Conclusions Ecigarettes were used mainly to quit smoking, and may be helpful for this purpose, but several respondents were concerned about potential toxicity. There are very few published studies on ecigarettes and research is urgently required, particularly on the efficacy and toxicity of these devices.

    The long-term effects of cannabis on human cognition are still unclear, but, considering that cannabis is a widely used substance and, overall, its potential use in therapeutic interventions, it is important to evaluate them. We hypothesize that the discrepancies among studies could be attributed to the specific cognitive function investigated and that skills subserved by the hippocampus, such as the spatial orientation abilities and, specifically, the ability to form and use cognitive maps, should be more compromised than others. Indeed it has been showed that cannabis users have a reduced hippocampus and that the hippocampus is the brain region in which cannabis has the greatest effect since it contains the highest concentration of cannabinoid receptors. To test this hypothesis we asked 15 heavy cannabis users and 19 nonusers to perform a virtual navigational test, the CMT, that assesses the ability to form and use cognitive maps. We found that using cannabis has no effect on these hippocampus-dependent orientation skills. We discuss the implications of our findings and how they relate to evidence reported in the literature that the intervention of functional reorganization mechanisms in cannabis user allows them to cope with the cognitive demands of navigational tasks.

    Full Text Available Introduction: Corporate portals are important in competitive organizations to transcend the search, retrieval and dissemination of information among stakeholders, contributing to the culture of interaction and knowledge sharing. Objective: The article presents the results of a master's degree research which analyzed the information searching behavior of users of corporate portals in Eletronorte. Methodology: Wilson's (1981 model of information-seeking behavior, focused on cognitive needs of information users, correlated to the proposal of Dias (2001b are used to characterize the corporate portal. The research uses quantitative and qualitative approaches in the analysis of collected data. Results: The main factors that stimulate the search for information in the portal are the centralized access to information and documents, with proper disclosure, as well as promoting information sharing among audiences of the organization. Conclusions: The Knowledge Portal represents a source of qualified information for decision making and spreading of organizational knowledge. The lack of a policy for information literacy and the culture of information sharing between users constitute themselves potential barriers to searching in corporate information portals.

  19. Understanding Contamination; Twenty Years of Simulating Radiological Contamination

    Energy Technology Data Exchange (ETDEWEB)

    2012-02-01

    A wide variety of simulated contamination methods have been developed by researchers to reproducibly test radiological decontamination methods. Some twenty years ago a method of non-radioactive contamination simulation was proposed at the Idaho National Laboratory (INL) that mimicked the character of radioactive cesium and zirconium contamination on stainless steel. It involved baking the contamination into the surface of the stainless steel in order to 'fix' it into a tenacious, tightly bound oxide layer. This type of contamination was particularly applicable to nuclear processing facilities (and nuclear reactors) where oxide growth and exchange of radioactive materials within the oxide layer became the predominant model for material/contaminant interaction. Additional simulation methods and their empirically derived basis (from a nuclear fuel reprocessing facility) are discussed. In the last ten years the INL, working with the Defense Advanced Research Projects Agency (DARPA) and the National Homeland Security Research Center (NHSRC), has continued to develop contamination simulation methodologies. The most notable of these newer methodologies was developed to compare the efficacy of different decontamination technologies against radiological dispersal device (RDD, 'dirty bomb') type of contamination. There are many different scenarios for how RDD contamination may be spread, but the most commonly used one at the INL involves the dispersal of an aqueous solution containing radioactive Cs-137. This method was chosen during the DARPA projects and has continued through the NHSRC series of decontamination trials and also gives a tenacious 'fixed' contamination. Much has been learned about the interaction of cesium contamination with building materials, particularly concrete, throughout these tests. The effects of porosity, cation-exchange capacity of the material and the amount of dirt and debris on the surface are very important factors

    2012-01-01

    Between September 2010 and May 2011 we evaluated three implementations of electronic referral (eReferral) systems at Hutt Valley, Northland and Canterbury District Health Boards in New Zealand. Qualitative and quantitative data were gathered through project documentation, database records and stakeholder interviews. This paper reports on the user perspectives based on interviews with 78 clinical, management and operational stakeholders in the three regions. Themes that emerge across the regions are compared and synthesised. Interviews focused on pre-planned domains including quality of referral, ease of use and patient safety, but agendas were adapted progressively to elaborate and triangulate on themes emerging from earlier interviews and to clarify indications from analysis of database records. The eReferral users, including general practitioners, specialists and administrative staff, report benefits in the areas of: (1) availability and transparency of referral-related data; (2) work transformation; (3) improved data quality and (4) the convenience of auto-population from the practice management system into the referral forms. eReferral provides enhanced visibility of referral data and status within the limits of the implementation (which only goes to the hospital door in some cases). Users in all projects indicated the desire to further exploit IT to enhance two-way communication between community and hospital. Reduced administrative handling is a clear work transformation benefit with mixed feedback regarding clinical workload impact. Innovations such as GP eReferral triaging teams illustrate the further potential for workflow transformation. Consistent structure in eReferrals, as well as simple legibility, enhances data quality. Efficiency and completeness is provided by auto-population of forms from system data, but opens issues around data accuracy. All three projects highlight the importance of user involvement in design, implementation and refinement. In

  2. Twenty-first century brain banking: at the crossroads.

    Graeber, Manuel B

    2008-05-01

    Brain banks form an increasingly important resource for research. In view of declining autopsy rates, brain banks are also gaining importance for medical diagnostics, quality control and teaching. In the case of neurodegenerative diseases, brain banks have become drivers of discovery and are yielding invaluable taxonomic references for neuropathologists. This article provides comments on two recent landmark papers in the field (Bell JE et al. Acta Neuropathol 2008. doi:10.1007/s00401-008-0358-8; Vonsattel JP et al. Acta Neuropathol 2008. doi:10.1007/s00401-007-0311-9). Professionalisation of brain banking standards, ethical principles safeguarding the running of a brain bank and a proposed code of conduct for brain bank staff are outlined and discussed. Special emphasis is placed on the need to enable sustainability of the human brain tissue resource in the face of increased financial pressures on medical institutions and raised public expectations towards ethical human brain banking in a globalised economic environment. It is proposed that brain banks undergo rigorous international audit as a prerequisite for their registration with the relevant national neuropathological society. This promises to be an important safeguard so that proper standards can be assured when tissue is handed out to commercial companies. Honesty, accountability and complete transparency are mandatory to allow long-lasting success of the brain banking operation by guaranteeing that the best possible use is made of the tissue. Preferred access by private tissue users must be avoided and money must never be allowed to buy access to a brain bank. Since brain banks operate internationally, any mistake made may be felt around the globe and could endanger the public's willingness to donate brains for research. The much-needed increase in the number of control brain donations will only be achievable if broad-based support from the general public can be won and maintained.

  3. Performance improvement of per-user threshold based multiuser switched scheduling system

    KAUST Repository

    Nam, Haewoon

    2013-01-01

    SUMMARY This letter proposes a multiuser switched scheduling scheme with per-user threshold and post user selection and provides a generic analytical framework for determining the optimal feedback thresholds. The proposed scheme applies an individual feedback threshold for each user rather than a single common threshold for all users to achieve some capacity gain due to the flexibility of threshold selection as well as a lower scheduling outage probability. In addition, since scheduling outage may occur with a non-negligible probability, the proposed scheme employs post user selection in order to further improve the ergodic capacity, where the user with the highest potential for a higher channel quality than other users is selected. Numerical and simulation results show that the capacity gain by post user selection is significant when random sequence is used.

    To verify if a mismatch negativity (MMN) paradigm based on speech syllables can differentiate between good and poorer cochlear implant (CI) users on a speech recognition task. Twenty adults with a CI and 11 normal hearing adults participated in the study. Based on a speech recognition test, ten CI users were classified as good performers and ten as poor performers. We measured the MMN with /da/ as the standard stimulus and /ba/ and /ga/ as the deviants. Separate analyses were conducted on the amplitude and latency of the MMN. A MMN was evoked by both deviant stimuli in all normal hearing participants and in well performing CI users, with similar amplitudes for both groups. However, the amplitude of the MMN was significantly reduced for the poorer CI users compared to the normal hearing group and the good CI users. The latency was longer for both groups of cochlear implant users. A bivariate correlation showed a significant positive correlation between the speech recognition score and the amplitude of the MMN. The MMN can distinguish between CI users who have good versus poor speech recognition as assessed with conventional tasks. Our findings suggest that the MMN can be use to assess speech recognition proficiency in CI users who cannot be tested with regular speech recognition tasks, like infants and other non-verbal populations.

    Mobility data has attracted the researchers for the past few years because of its rich context and spatiotemporal nature, where this information can be used for potential applications like early warning system, route prediction, traffic management, advertisement, social networking, and community finding. All the mentioned applications are based on mobility profile building and user trend analysis, where mobility profile building is done through significant places extraction, user's actual movement prediction, and context awareness. However, significant places extraction and user's actual movement prediction for mobility profile building are a trivial task. In this paper, we present the user similarity mining-based methodology through user mobility profile building by using the semantic tagging information provided by user and basic GSM network architecture properties based on unsupervised clustering approach. As the mobility information is in low-level raw form, our proposed methodology successfully converts it to a high-level meaningful information by using the cell-Id location information rather than previously used location capturing methods like GPS, Infrared, and Wifi for profile mining and user similarity mining.

  13. A Remote User Authentication Scheme with Anonymity for Mobile Devices

    Directory of Open Access Journals (Sweden)

    2012-04-01

    Full Text Available With the rapid growth of information technologies, mobile devices have been utilized in a variety of services such as e-commerce. When a remote server provides such e-commerce services to a user, it must verify the legitimacy of the user over an insecure communication channel. Therefore, remote user authentication has been widely deployed to verify the legitimacy of remote user login requests using mobile devices like smart cards. In this paper we propose a smart card-based authentication scheme that provides both user anonymity and mutual authentication between a remote server and a user. The proposed authentication scheme is a simple and efficient system applicable to the limited resource and low computing performance of the smart card. The proposed scheme provides not only resilience to potential attacks in the smart card-based authentication scheme, but also secure authentication functions. A smart card performs a simple one-way hash function, the operations of exclusive-or and concatenation in the authentication phase of the proposed scheme. The proposed scheme also provides user anonymity using a dynamic identity and key agreement, and secure password change.

    RAVEN is a generic software framework to perform parametric and probabilistic analysis based on the response of complex system codes. The initial development was aimed to provide dynamic risk analysis capabilities to the Thermo-Hydraulic code RELAP-7, currently under development at the Idaho National Laboratory (INL). Although the initial goal has been fully accomplished, RAVEN is now a multi-purpose probabilistic and uncertainty quantification platform, capable to agnostically communicate with any system code. This agnosticism includes providing Application Programming Interfaces (APIs). These APIs are used to allow RAVEN to interact with any code as long as all the parameters that need to be perturbed are accessible by input files or via python interfaces. RAVEN is capable of investigating the system response, and investigating the input space using Monte Carlo, Grid, or Latin Hyper Cube sampling schemes, but its strength is focused toward system feature discovery, such as limit surfaces, separating regions of the input space leading to system failure, using dynamic supervised learning techniques. The development of RAVEN started in 2012, when, within the Nuclear Energy Advanced Modeling and Simulation (NEAMS) program, the need to provide a modern risk evaluation framework became stronger. RAVEN principal assignment is to provide the necessary software and algorithms in order to employ the concept developed by the Risk Informed Safety Margin Characterization (RISMC) program. RISMC is one of the pathways defined within the Light Water Reactor Sustainability (LWRS) program. In the RISMC approach, the goal is not just the individuation of the frequency of an event potentially leading to a system failure, but the closeness (or not) to key safety-related events. Hence, the approach is interested in identifying and increasing the safety margins related to those events.

    2002-11-15

    Attempts at interface agent personalization are usually aimed at helping the user perform a task or service. For example,scheduling of appointments, inspection of messages, discovering items of interest and different forms of negotiation. While this is very noble undertaking, it makes assumptions about the level of trust and credibility a user may place in such an agent in a realworld setting. If Microsoft's experiments in social user interfaces teach us anything, it is that a ''one size fits all'' solution does not truly engage the user and encourage reuse. This ''relationship management'' between the user and the character begins when the two first meet. As with human-human relationships, first impressions are essential. Instead of looking at the functional aspects of the relationship, we believe the characters embodiment is the best place to start the personalization process. We describe a study in which participants from several different age ranges,genders and ethnic groups were asked their preference of anthropomorphic character, based on a cooperative computer task. We found that participants generally selected characters from the same ethic group as themselves and that almost all participants selected a young character (instead of a middle aged or elderly character). No significant preference was found for character gender.

    An ideal in mental health care is user participation. This implies inclusion and facilitation by clinicians to enable users to participate in decisions about themselves and in the design of suitable treatment. However, much of the work of clinicians consists of handovers and other meetings where patients are not present. It is therefore interesting to study how the patient perspective is handled in such meetings and whether it forms a basis for user participation. We conducted fieldwork in three different inpatient wards in Norwegian District Psychiatric Centres. We used an interactional perspective in our analysis, where speech acts, framing and footing were key concepts. The findings show that the talk in the handovers and meetings contained five main themes and that there was a clear correlation between what was said and how it was said, and whether clinicians related to the content in a decisive, person-centred or indecisive manner. We discuss potential participation statuses for patients and their limited opportunity to influence the talk and possible decisions about themselves. Our conclusion is that handover meetings primarily function as an aid in organising clinicians' work and could ultimately be seen as counteracting user participation.

  19. Does quality of life depend on speech recognition performance for adult cochlear implant users?

    Current postoperative clinical outcome measures for adults receiving cochlear implants (CIs) consist of testing speech recognition, primarily under quiet conditions. However, it is strongly suspected that results on these measures may not adequately reflect patients' quality of life (QOL) using their implants. This study aimed to evaluate whether QOL for CI users depends on speech recognition performance. Twenty-three postlingually deafened adults with CIs were assessed. Participants were tested for speech recognition (Central Institute for the Deaf word and AzBio sentence recognition in quiet) and completed three QOL measures-the Nijmegen Cochlear Implant Questionnaire; either the Hearing Handicap Inventory for Adults or the Hearing Handicap Inventory for the Elderly; and the Speech, Spatial and Qualities of Hearing Scale questionnaires-to assess a variety of QOL factors. Correlations were sought between speech recognition and QOL scores. Demographics, audiologic history, language, and cognitive skills were also examined as potential predictors of QOL. Only a few QOL scores significantly correlated with postoperative sentence or word recognition in quiet, and correlations were primarily isolated to speech-related subscales on QOL measures. Poorer pre- and postoperative unaided hearing predicted better QOL. Socioeconomic status, duration of deafness, age at implantation, duration of CI use, reading ability, vocabulary size, and cognitive status did not consistently predict QOL scores. For adult, postlingually deafened CI users, clinical speech recognition measures in quiet do not correlate broadly with QOL. Results suggest the need for additional outcome measures of the benefits and limitations of cochlear implantation. 4.

    Communication problems in social network forums related to health are currently of interest. This study analyzed the communication between users and health workers in the board of Family Health. This is a qualitative study, in which the Habermas' Theory of Communicative Action was the theoretical framework used. Data collected revealed two intertwined dimensions: estrangements and approximations between users and health workers. In relation to estrangements, asymmetrical relationships are highlighted, characterized by coercion and manipulation on the part of the health workers, which are practices that harm the participation of users. On the other hand, moments of interaction and fights for rights addressed during approximations between users and health workers are also present. Finally, we argue that communication in the committees of Family Health present potentialities and limitations and should be discussed, especially through permanent health education.

  1. A Driving Behaviour Model of Electrical Wheelchair Users

    Directory of Open Access Journals (Sweden)

    S. O. Onyango

    2016-01-01

    Full Text Available In spite of the presence of powered wheelchairs, some of the users still experience steering challenges and manoeuvring difficulties that limit their capacity of navigating effectively. For such users, steering support and assistive systems may be very necessary. To appreciate the assistance, there is need that the assistive control is adaptable to the user’s steering behaviour. This paper contributes to wheelchair steering improvement by modelling the steering behaviour of powered wheelchair users, for integration into the control system. More precisely, the modelling is based on the improved Directed Potential Field (DPF method for trajectory planning. The method has facilitated the formulation of a simple behaviour model that is also linear in parameters. To obtain the steering data for parameter identification, seven individuals participated in driving the wheelchair in different virtual worlds on the augmented platform. The obtained data facilitated the estimation of user parameters, using the ordinary least square method, with satisfactory regression analysis results.

    Online communications at web portals represents technology-mediated user interactions, leading to massive data and potentially new techno-social phenomena not seen in real social mixing. Apart from being dynamically driven, the user interactions via posts is indirect, suggesting the importance of the contents of the posted material. We present a systematic way to study Blog data by combined approaches of physics of complex networks and computer science methods of text analysis. We are mapping the Blog data onto a bipartite network where users and posts with comments are two natural partitions. With the machine learning methods we classify the texts of posts and comments for their emotional contents as positive or negative, or otherwise objective (neutral). Using the spectral methods of weighted bipartite graphs, we identify topological communities featuring the users clustered around certain popular posts, and underly the role of emotional contents in the emergence and evolution of these communities.

  4. Do recommender systems benefit users?

    CERN Document Server

    Yeung, Chi Ho

    2015-01-01

    Recommender systems are present in many web applications to guide our choices. They increase sales and benefit sellers, but whether they benefit customers by providing relevant products is questionable. Here we introduce a model to examine the benefit of recommender systems for users, and found that recommendations from the system can be equivalent to random draws if one relies too strongly on the system. Nevertheless, with sufficient information about user preferences, recommendations become accurate and an abrupt transition to this accurate regime is observed for some algorithms. On the other hand, we found that a high accuracy evaluated by common accuracy metrics does not necessarily correspond to a high real accuracy nor a benefit for users, which serves as an alarm for operators and researchers of recommender systems. We tested our model with a real dataset and observed similar behaviors. Finally, a recommendation approach with improved accuracy is suggested. These results imply that recommender systems ...

    2013-01-01

    Agile development methods began to emerge around 20 years ago. However, it was not until the early 2000s that they began to be widely used in industry. This growth was often due to the advent of Internet services requiring faster cycles of development in order to heighten the rate at which an ever-greater number of functionalities were made available. In parallel, user-centered design (UCD) methods were also becoming more and more widely used: hence, user-centered design and agile methods were bound to cross paths, at least in the telecoms industry! During this period, in the field of telec

    Full Text Available Drupal is a powerful, but complex, Web Content Management System, being adopted by many libraries. Installing Drupal typically involves adding additional modules for flexibility and increased functionality. Although installing additional modules does increase functionality, it inevitably complicates usability. At the University of Houston Libraries, the Web Services department researched what modules work well together to accomplish a simpler interface while simultaneously providing the flexibility and advanced tools needed to create a successful user experience within Drupal. This article explains why particular modules were chosen or developed, how the design enhanced the user experience, how the CMS architecture was created, and how other library systems were integrated into Drupal.

    It is a qualitative research, which aimed to evaluate the user embracement and attachment in the humanization of nursing care for people with Diabetes Mellitus in a public specialized outpatient service. The theoretical support was the National Policy of Humanization of the Health Ministry / Brazil. Data was collected through semi-structured interviews with twenty people with type 1 or type 2 diabetes, between 2010 March and May. The analysis resulted in four categories that explore listening and dialogue, relationships, problem solving and access. People with diabetes recognize the user embracement and attachment as part of humanized attention given, which is highlighted by the appreciation of the patients' subjective dimension.

    2005-01-01

    Differences in cellular phones' complexity and their impact on children's performance are under study in this experiment. Twenty children (age 9-14 years) solved tasks on two phones that were simulated according to existing models on a PC with a touch screen, holding constant display size, fonts, and colors. Actions were logged and analyzed regarding execution time, detour steps, and specific errors. Results show that children using the Siemens C35i with 25% higher complexity (with regard to number of required production rules) spent double the time solving tasks and undertook three times as many detour steps as children using the less complex Nokia 3210. A detailed analysis of user actions revealed that the number of production rules to be learned fails to account for most difficulties. Instead, ambiguous naming, poor categorization of functions, and unclear functionality of keys undermined performance. Actual or potential applications of this research include guidelines to improve the usability of all devices with small displays and hierarchical menu structures, such as cellular phones.

    Retreat of mountain glaciers is a significant contributor to sea-level rise and a potential threat to human populations through impacts on water availability and regional hydrology. Like most of Earth’s mountain glaciers, those in western North America are experiencing rapid mass loss. Projections of future large-scale mass change are based on surface mass balance models that are open to criticism, because they ignore or greatly simplify glacier physics. Here we use a high-resolution regional glaciation model, developed by coupling physics-based ice dynamics with a surface mass balance model, to project the fate of glaciers in western Canada. We use twenty-first-century climate scenarios from an ensemble of global climate models in our simulations; the results indicate that by 2100, the volume of glacier ice in western Canada will shrink by 70 +/- 10% relative to 2005. According to our simulations, few glaciers will remain in the Interior and Rockies regions, but maritime glaciers, in particular those in northwestern British Columbia, will survive in a diminished state. We project the maximum rate of ice volume loss, corresponding to peak input of deglacial meltwater to streams and rivers, to occur around 2020-2040. Potential implications include impacts on aquatic ecosystems, agriculture, forestry, alpine tourism and water quality.

    It was a little over twenty years ago that two groups, one in the U.S. and another in Hull, U.K. working independently, reported that ultraviolet laser pulses of nanosecond duration were capable of etching organic polymer films without any need for further development.In 1982, our group at the IBM Research Center which studied this phenomenon at 193nm named the process "Ablative Photodecomposition". Dyer and his group in Hull reported similar results at 248nm and 308nm in 1983. We also showed that the process worked well in the etching of tissue and had the potential to be of use in surgery since there was no detectable heat damage around the exposed area. These reports led to a burst of activity from numerous groups all over the world which has not slowed down significantly to the present day. The driving force behind the activity was and continues to be the potential for applications in several areas of computer hardware technology as well as in corneal refractive surgery. Today these applications can be said to be firmly in place and well-accepted. Strangely, the science behind the process is still a subject for serious discussion. The reason for this is the mix of physicists, chemists, medical doctors and engineers who have stepped into the debate. The result is a true 'Babel' which will be pointed out.

Data Source: Spanish and international databases, between January 2006 - March 2011. Keywords: Contraceptives, Postcoital pills, emergency contraception, levonorgestrel, data collection. Study selection: original papers, letters to the editor in which stated aims were the description, prediction or measurement of variables related to EC use. Twenty-two papers were retrieved and fourteen were finally selected, all of which were descriptive. Data extraction: manuscripts were evaluated by two independent reviewers. Results: Women requesting EC have ages between 21-24 years, mostly single and university students; declare that they have not previously used EC, and attend an Emergency department, at weekends and within 48 hours following unprotected sexual intercourse. The reason is condom rupture. None of the studies reviewed measured alcohol and other drug consumption, the number of sexual partners, nor any of the studies performed a comparison with a group not using EC. Conclusions: lack of homogeneity and comprehensiveness of studied variables resulted in a limited profile of Spanish EC users. Further studies are needed with a more comprehensive approach if sexual health interventions are to be carried out in possible users.

Recently, the second version of the GOCE User Toolbox (GUT) was developed to enhance the exploitation of GOCE level 2 data with ERS ENVISAT altimetry. The developments of GUT focused on the following issues: Data Extraction, Generation, Filtering, and Data Save and Restore Without any doubt the development of the GOCE user toolbox have played a major role in paving the way to successful use of the GOCE data for oceanography. The results of the preliminary analysis carried out in this phase of the GUTS project have already demonstrated a significant advance in the ability to determine the ocean's general circulation. The improved gravity models provided by the GOCE mission have enhanced the resolution and sharpened the boundaries of those features compared with earlier satellite only solutions. Calculation of the geostrophic surface currents from the MDT reveals improvements for all of the ocean's major current systems.
