    Hall, Danika V; Jones, Sandra C; Iverson, Donald C

    To examine the nature of disease awareness advertising (DAA). Therapeutic advertisements in six popular Australian women's magazines were monitored between April 2006 and March 2007. A subset of advertisements was included in the study based on criteria derived from a definition of DAA. Unique advertisements were analysed by four independent coders. Types of advertisements and their sponsors, the types of disease information present, and the persuasive techniques utilised. Of 711 advertisements identified, 60 met the inclusion criteria for DAA, and 30 of these were unique. Over one-third of the advertisements were classified as "unbranded product advertisements", which promote a product without referring directly to a brand. DAA sponsored by pharmaceutical companies most often provided treatment and prevalence information. Most (22/30) advertisements used emotional appeals; 15 of these used "happiness/healthiness/wellbeing". The educational value of industry-sponsored DAA could be improved if regulations and guidelines stipulated disease information requirements, such as inclusion of risk-factor and symptom information. Regulators should provide guidelines for "unbranded product advertisements" and the acceptability of other persuasive techniques. Further research into DAA is required and should consider advertisements in a range of media, and behavioural responses.

    INSPIRE-00545541; Charpentier, Philippe; Ustyuzhanin, Andrey

    2015-12-23

    This paper presents an algorithm providing recommendations for optimizing the LHCb data storage. The LHCb data storage system is a hybrid system. All datasets are kept as archives on magnetic tapes. The most popular datasets are kept on disks. The algorithm takes the dataset usage history and metadata (size, type, configuration etc.) to generate a recommendation report. This article presents how we use machine learning algorithms to predict future data popularity. Using these predictions it is possible to estimate which datasets should be removed from disk. We use regression algorithms and time series analysis to find the optimal number of replicas for datasets that are kept on disk. Based on the data popularity and the number of replicas optimization, the algorithm minimizes a loss function to find the optimal data distribution. The loss function represents all requirements for data distribution in the data storage system. We demonstrate how our algorithm helps to save disk space and to reduce waiting times ...

  5. A Popularity-Aware Semantic Overlay for Efficient Peer-to-Peer Search

    Directory of Open Access Journals (Sweden)

    LEE, C.

    2014-11-01

    Full Text Available This paper presents a novel semantic overlay scheme that connects peers based on the similarity of their contents. Semantic closeness among overlay peers can effectively be determined via the exchanges of their content summary using Bloom filters. The overlay link quality is further improved by carefully selecting semantic neighbors according to their potential to contribute to content-based searches. The basic idea behind the semantic neighbor selection is that highly replicated documents should not excessively dominate the overlay topology, overshadowing rare to modestly-replicated items whose query efficiency is often more critical for overall search performance. The efficacy of the proposed semantic overlay is validated through our simulation study which demonstrates superior overlay link quality and query routing performance.

  6. What Combinations of Contents is Driving Popularity in IPTV-based Social Networks?

    Science.gov (United States)

    Bhatt, Rajen

    IPTV-based Social Networks are gaining popularity with TV programs coming over IP connection and internet like applications available on home TV. One such application is rating TV programs over some predefined genres. In this paper, we suggest an approach for building a recommender system to be used by content distributors, publishers, and motion pictures producers-directors to decide on what combinations of contents may drive popularity or unpopularity. This may be used then for creating a proper mixture of media contents which can drive high popularity. This may also be used for the purpose of catering customized contents for group of users whose taste is similar and thus combinations of contents driving popularity for a certain group is also similar. We use a novel approach for this formulation utilizing fuzzy decision trees. Computational experiments performed over real-world program review database shows that the proposed approach is very efficient towards understanding of the content combinations.

    2015-05-01

    Scientific debate continues into whether hypoxic training has any performance benefit for athletes, and although this type of training seems popular, to our knowledge little empirical evidence on its popularity with endurance-based athletes exists. To quantify the usage of hypoxic training in endurance-based athletes we asked 203 athletes (amateur = 108, professional = 95) to complete a 17-question survey during 2013-2014 season. Compared to amateurs, professional athletes were 4.5 times (3.0-6.8, odds ratio, 95% confidence limits) more likely to undertake hypoxic training. Live-high train-low was the most popular hypoxic training protocol for athletes (52% professional and 80% amateur) with live-high train-high also used (38% professional, 20% amateur). Compared to amateurs, professional athletes tended to use evidence-based hypoxic training methods, seek advice on hypoxic training from reliable sources and were generally more realistic about the potential performance gains as a result of hypoxic training. Almost one third (25-30%) of all athletes suffered illness during their hypoxic training. Compared to amateurs, professional athletes are more likely to undertake hypoxic training and tend to follow current scientific guidelines. Attenuation of the ill effects that occur during hypoxic training may be accomplished if athletes give more attention to monitoring stress and training levels. Copyright © 2015 Elsevier Inc.

    2017-05-01

    Accuracy and diversity are two important measures in evaluating the performance of recommender systems. It has been demonstrated that the recommendation model inspired by the heat conduction process has high diversity yet low accuracy. Many variants have been introduced to improve the accuracy while keeping high diversity, most of which regard the current node-degree of an item as its popularity. However in this way, a few outdated items of large degree may be recommended to an enormous number of users. In this paper, we take the recent popularity (recently increased item degrees) into account in the heat-conduction based methods, and propose accordingly the improved recommendation models. Experimental results on two benchmark data sets show that the accuracy can be largely improved while keeping the high diversity compared with the original models.

    Beermann, T; The ATLAS collaboration; Maettig, P

    2014-01-01

    This paper presents a system to predict future data popularity for data-intensive systems, such as ATLAS distributed data management (DDM). Using these predictions it is possible to make a better distribution of data, helping to reduce the waiting time for jobs using with this data. This system is based on a tracer infrastructure that is able to monitor and store historical data accesses and which is used to create popularity reports. These reports provide detailed summaries about data accesses in the past, including information about the accessed files, the involved users and the sites. From this past data it is possible to then make near-term forecasts for data popularity in the future. The prediction system introduced in this paper makes use of both simple prediction methods as well as predictions made by neural networks. The best prediction method is dependent on the type of data and the data is carefully filtered for use in either system. The second part of the paper introduces a system that effectively ...

  14. Normalizing Item-Based Collaborative Filter Using Context-Aware Scaled Baseline Predictor

    Directory of Open Access Journals (Sweden)

    Wenming Ma

    2017-01-01

    Full Text Available Item-based collaborative filter algorithms play an important role in modern commercial recommendation systems (RSs. To improve the recommendation performance, normalization is always used as a basic component for the predictor models. Among a lot of normalizing methods, subtracting the baseline predictor (BLP is the most popular one. However, the BLP uses a statistical constant without considering the context. We found that slightly scaling the different components of the BLP separately could dramatically improve the performance. This paper proposed some normalization methods based on the scaled baseline predictors according to different context information. The experimental results show that using context-aware scaled baseline predictor for normalization indeed gets better recommendation performance, including RMSE, MAE, precision, recall, and nDCG.

  15. Implementing data placement strategies for the CMS experiment based on a popularity mode

    CERN Multimedia

    CERN. Geneva; Barreiro Megino, Fernando Harald

    2012-01-01

    During the first two years of data taking, the CMS experiment has collected over 20 PetaBytes of data and processed and analyzed it on the distributed, multi-tiered computing infrastructure on the WorldWide LHC Computing Grid. Given the increasing data volume that has to be stored and efficiently analyzed, it is a challenge for several LHC experiments to optimize and automate the data placement strategies in order to fully profit of the available network and storage resources and to facilitate daily computing operations. Building on previous experience acquired by ATLAS, we have developed the CMS Popularity Service that tracks file accesses and user activity on the grid and will serve as the foundation for the evolution of their data placement. A fully automated, popularity-based site-cleaning agent has been deployed in order to scan Tier2 sites that are reaching their space quota and suggest obsolete, unused data that can be safely deleted without disrupting analysis activity. Future work will be to demons...

  16. Effects of awareness diffusion and self-initiated awareness behavior on epidemic spreading - An approach based on multiplex networks

    Science.gov (United States)

    Kan, Jia-Qian; Zhang, Hai-Feng

    2017-03-01

    In this paper, we study the interplay between the epidemic spreading and the diffusion of awareness in multiplex networks. In the model, an infectious disease can spread in one network representing the paths of epidemic spreading (contact network), leading to the diffusion of awareness in the other network (information network), and then the diffusion of awareness will cause individuals to take social distances, which in turn affects the epidemic spreading. As for the diffusion of awareness, we assume that, on the one hand, individuals can be informed by other aware neighbors in information network, on the other hand, the susceptible individuals can be self-awareness induced by the infected neighbors in the contact networks (local information) or mass media (global information). Through Markov chain approach and numerical computations, we find that the density of infected individuals and the epidemic threshold can be affected by the structures of the two networks and the effective transmission rate of the awareness. However, we prove that though the introduction of the self-awareness can lower the density of infection, which cannot increase the epidemic threshold no matter of the local information or global information. Our finding is remarkably different to many previous results on single-layer network: local information based behavioral response can alter the epidemic threshold. Furthermore, our results indicate that the nodes with more neighbors (hub nodes) in information networks are easier to be informed, as a result, their risk of infection in contact networks can be effectively reduced.

  17. Dimensionality Reduction for Hyperspectral Data Based on Class-Aware Tensor Neighborhood Graph and Patch Alignment.

    2015-08-01

    To take full advantage of hyperspectral information, to avoid data redundancy and to address the curse of dimensionality concern, dimensionality reduction (DR) becomes particularly important to analyze hyperspectral data. Exploring the tensor characteristic of hyperspectral data, a DR algorithm based on class-aware tensor neighborhood graph and patch alignment is proposed here. First, hyperspectral data are represented in the tensor form through a window field to keep the spatial information of each pixel. Second, using a tensor distance criterion, a class-aware tensor neighborhood graph containing discriminating information is obtained. In the third step, employing the patch alignment framework extended to the tensor space, we can obtain global optimal spectral-spatial information. Finally, the solution of the tensor subspace is calculated using an iterative method and low-dimensional projection matrixes for hyperspectral data are obtained accordingly. The proposed method effectively explores the spectral and spatial information in hyperspectral data simultaneously. Experimental results on 3 real hyperspectral datasets show that, compared with some popular vector- and tensor-based DR algorithms, the proposed method can yield better performance with less tensor training samples required.

  19. Trust-Based and Context-Aware Authentication in a Software Architecture for Context and Proximity-Aware Services

    Science.gov (United States)

    Lenzini, Gabriele

    We describe an existing software architecture for context and proximity aware services that enables trust-based and context-aware authentication. A service is proximity aware when it automatically detects the presence of entities in its proximity. Authentication is context-aware when it uses contextual information to discern among different identities and to evaluate to which extent they are authentic. The software architecture that we describe here is functioning in our Institute: It manages a sensor network to detect the presence and location of users and their devices. A context manager is responsible to merge the different sources of contextual information, to solve potential contradictions, and to determine the level of authentication of the identity of the person approaching one of the services offered in the coffee-break corners of our Institute. In our solution for context-aware authentication, sensors are managed as if they were recommenders having subjective belief, disbelief, and uncertainty (i.e., trust) on the position and identity of users. A sensor’s subjective trust depends on what it has been sensing in the environment. We discuss the results of an array of simulations that we conducted to validate our concept of trust-based and context-aware authentication. We use Subjective Logic to manage trust.

    Full Text Available The article deals with the problems of the communication of popular culture. It considers the more specialized meaning of popular culture, which primarily encompasses the works of artistic forms which have a popular character - easily understandable and entertaining contents and wide audience. The aesthetic communication of the popular through popular literature, film, pop and rock music is examined. The paper is divided into three parts. The first parts deals with the aesthetics of the communication of popular culture. It contains the analysis of the major formal-aesthetic procedures embedded in the creative expression of the popular. In the part which is dedicated to social aspects of the communication of popular art, the author examines the industrial, market and commercial principles upon which this whole culture is based. It is a time of new technologies and mass consumption, which represent, in the words of Eric Hobsbawm, a 'cultural landscape' that has transformed the manner in which a new audience experiences the artistic. Finally, popular culture stars are observed as communicators. The author adds them as a new, even crucial, link in the already known chain of communication comprising the author, the work and the audience. Stars (film, popular music are active factors of communication as well as its bearers. They are the intermediaries through which the audience establishes relationships with the authors (writers, directors, composers and the works in which those stars appear. Stars as 'new Olympians' (Morin are, indeed, another significant category that distinguishes the communication of popular culture.

    Becker's theory of taste-based discrimination predicts that relative employment of the discriminated social group will improve if there is a decrease in the level of prejudice for the marginally discriminating employer. In this paper we experimentally test this prediction offered by Garry Becker in his seminal work on taste based discrimination, in the context of caste in India, with management students (potential employers in the near future) as subjects. First, we measure caste prejudice and show that awareness through a TV social program reduces implicit prejudice against the lower caste and the reduction is sustained over time. Second, we find that the treatment reduces the prejudice levels of those in the left tail of the prejudice distribution--the group which can potentially affect real outcomes as predicted by the theory. And finally, a larger share of the treatment group subjects exhibit favorable opinion about reservation in jobs for the lower caste.

    2011-06-01

    Full Text Available A Network Management System (NMS plays a very important role in managing an ever-evolving telecommunication network. Generally an NMS monitors & maintains the health of network elements. The growing size of the network warrants extra functionalities from the NMS. An NMS provides all kinds of information about networks which can be used for other purposes apart from monitoring & maintaining networks like improving QoS & saving energy in the network. In this paper, we add another dimension to NMS services, namely, making an NMS energy aware. We propose a Decision Management System (DMS framework which uses a machine learning technique called Bayesian Belief Networks (BBN, to make the NMS energy aware. The DMS is capable of analysing and making control decisions based on network traffic. We factor in the cost of rerouting and power saving per port. Simulations are performed on standard network topologies, namely, ARPANet and IndiaNet. It is found that ~2.5-6.5% power can be saved.

    Full Text Available Most of the currently developed systems are based on the client-server architecture. This architecture is usedeverywhere, from mobile-native development to Web applications.However implementing an application based on this architectural solution requires quite a lot of effort from the softwaredeveloper, and therefore, in order to simplify and speed up the development, certain standard solutions and approachesappeared. This article will discuss the most popular technologies used in the development of Web applications in the context ofenterprise development.Also in this article will be mentioned the project, built on the architecture of "client-server" - ScienceToMetrics.The main theme of this project is the study of science-metric indicators for the structural divisions of the faculty of theOdessa National Academy of Food Technologies. In fact, it is a portal for viewing and editing information on employees, inthe future this portal may be extended to subprojects.In this project, the main idea of this architecture was embodied: decomposition of the application into atomic parts inorder to distribute it to several hardware units of capacity to improve performance. The client is an independent application,which at the same time receives information from an external API-interface through REST-requests. In turn, the backendprovides this API with certain security restrictions on the content provided. The backend for this architecture provides a layerfor the content of the data users, whether it's a database (NoSQL, SQL or an integration API with external aggregationsystems. To ensure the necessary level of security, JWT (Javascript Web Token authorization is used, which allows you not tocreate an explicit session between the client and the backend, but allows you to communicate through a token that stores allthe necessary meta-information for this user.

    2016-01-01

    Enhancing sales and operations planning through forecasting analysis and business intelligence is demanded in many industries and enterprises. Publishing industries usually pick attractive titles and headlines for their stories to increase sales, since popular article titles and headlines can attract readers to buy magazines. In this paper, information retrieval techniques are adopted to extract words from article titles. The popularity measures of article titles are then analyzed by using the search indexes obtained from Google search engine. Backpropagation Neural Networks (BPNNs) have successfully been used to develop prediction models for sales forecasting. In this study, we propose a novel hybrid neural network model for sales forecasting based on the prediction result of time series forecasting and the popularity of article titles. The proposed model uses the historical sales data, popularity of article titles, and the prediction result of a time series, Autoregressive Integrated Moving Average (ARIMA) forecasting method to learn a BPNN-based forecasting model. Our proposed forecasting model is experimentally evaluated by comparing with conventional sales prediction techniques. The experimental result shows that our proposed forecasting method outperforms conventional techniques which do not consider the popularity of title words.

    Bao, X.; Cai, X.; Liu, Y.

    2009-12-01

    Understanding spatiotemporal dynamics of hydrological events such as storms and droughts is highly valuable for decision making on disaster mitigation and recovery. Virtual Globe-based technologies such as Google Earth and Open Geospatial Consortium KML standards show great promises for collaborative exploration of such events using visual analytical approaches. However, currently there are two barriers for wider usage of such approaches. First, there lacks an easy way to use open source tools to convert legacy or existing data formats such as shapefiles, geotiff, or web services-based data sources to KML and to produce time-aware KML files. Second, an integrated web portal-based time-aware animation tool is currently not available. Thus users usually share their files in the portal but have no means to visually explore them without leaving the portal environment which the users are familiar with. We develop a web portal-based time-aware KML animation tool for viewing extreme hydrologic events. The tool is based on Google Earth JavaScript API and Java Portlet standard 2.0 JSR-286, and it is currently deployable in one of the most popular open source portal frameworks, namely Liferay. We have also developed an open source toolkit kml-soc-ncsa (http://code.google.com/p/kml-soc-ncsa/) to facilitate the conversion of multiple formats into KML and the creation of time-aware KML files. We illustrate our tool using some example cases, in which drought and storm events with both time and space dimension can be explored in this web-based KML animation portlet. The tool provides an easy-to-use web browser-based portal environment for multiple users to collaboratively share and explore their time-aware KML files as well as improving the understanding of the spatiotemporal dynamics of the hydrological events.

Secondary objectives were to ascertain determinants of self-initiated deprescribing conversations and to identify how older adults seek information on medication harms. Cross-sectional population-based household telephone survey using random-digit dialling. Canada. Community-dwelling adults aged 65 and older (N = 2,665; n = 898 men, n = 1,767 women, mean age 74.9 ± 7.2, range 65-100). Information was gathered on age; sex; awareness of the term "deprescribing"; knowledge and information-seeking behaviors related to medication harms; and previous initiation of a deprescribing conversation with a healthcare professional. Three targeted classes of potentially inappropriate prescriptions were asked about: sedative-hypnotics, glyburide, and proton pump inhibitors. Descriptive statistics and regression analyses were used to quantify associations. Two-thirds (65.2%, 95% confidence interval (CI) = 63.4-67.0%) of participants were familiar with the concept of medication-induced harms. Only 6.9% (95% CI = 5.9-7.8%) recognized the term deprescribing; 48% (95% CI = 46-50%) had researched medication-related harms. Older adults most commonly sought information from the Internet (35.5%, 95% CI = 33.4-37.6%), and from health care professionals (32.2%, 95% CI = 30.1-34.3%). Patient-initiated deprescribing conversations were associated with awareness of medication harms (odds ratio (OR) = 1.74, 95% CI = 1.46-2.07), familiarity with the term deprescribing (OR = 1.55, 95% CI = 1.13-2.12), and information-seeking behaviors (OR = 4.57, 95% CI = 3.84-5.45), independent of age and sex. Healthcare providers can facilitate patient-initiated deprescribing conversations by providing information on medication harms and using the term "deprescribing." © 2017 The Authors.

    In the last years the increase in marine traffic generated the necessity of global monitoring for marine environment management in terms of safety, security and fisheries. The increasing number of new satellite-based Synthetic Aperture Radar (SAR) systems, and the intrinsic capability of the transmitted electromagnetic pulses to interact with the ships and to retrieve its cinematic characteristics, made this instrument particularly fit to improve global maritime awareness through the fusion with cooperative data (AIS, VMS, LRIT). The growing need of global maritime awareness gave a push to the realization of different projects in the European context, each one focused on a different particular objective. Particularly useful is the synergy between the operational and research aspects, being the goal of the last to improve the state of the art in the field of ship detection. Two European projects are the key to strive this synergy: the project MARitime Security Service (MARISS), which implements the operational capability, and the R&D Dolphin projects, which is focused on the deep exploitation of remote sensing data and on the technological development of advanced techniques for ship detection and classification purposes, and Seabilla project, which is also dedicated to improve the current ship detection capability and to fuse all the available information from different data sources for border surveillance optimization. This paper introduces the multipurpose Edisoft Vessel Detection software (EdiVDC) implemented by the EDISOFT company, which comes from the necessity to respect increasingly stringent requirements in terms of ship detection. The EdiVDC software is being operationally used in the framework of the MARISS project and it integrates advanced processing algorithms, developed in the scope of the Dolphin project with the cooperation of ISEL-IT (Instituto de Telecomunicações), and data simulators, developed in the context of the Seabilla project, improving

    2015-09-01

    Full Text Available Wireless Sensor Network (WSN has emerged as an important supplement to the modern wireless communication systems due to its wide range of applications. The recent researches are facing the various challenges of the sensor network more gracefully. However, energy efficiency has still remained a matter of concern for the researches. Meeting the countless security needs, timely data delivery and taking a quick action, efficient route selection and multi-path routing etc. can only be achieved at the cost of energy. Hierarchical routing is more useful in this regard. The proposed algorithm Energy Aware Cluster Based Routing Scheme (EACBRS aims at conserving energy with the help of hierarchical routing by calculating the optimum number of cluster heads for the network, selecting energy-efficient route to the sink and by offering congestion control. Simulation results prove that EACBRS performs better than existing hierarchical routing algorithms like Distributed Energy-Efficient Clustering (DEEC algorithm for heterogeneous wireless sensor networks and Energy Efficient Heterogeneous Clustered scheme for Wireless Sensor Network (EEHC.

    Using popular culture to engage students in discussions of HIV prevention is a nontraditional approach that may complement current prevention efforts and enhance the ability to reach youth who are at high risk of contracting HIV and other sexually transmitted infections. Hip-hop or rap music is the dominant genre of music among adolescents, especially Black and Latino youth who are disproportionately impacted by HIV and AIDS. This paper describes the rationale and development of the Reducing HIV and AIDS through Prevention (RHAP) program, a school-based program that uses hip-hop/rap music as a vehicle for raising awareness among adolescents about HIV/AIDS. Constructs from the Social Cognitive Theory and the Sexual Script Theory were used in developing the program. It was piloted and evaluated among 26 middle school students in East Harlem, New York. The lessons learned from a formative evaluation of the program and the implications for developing other programs targeting public health problems are discussed. The RHAP program challenges the traditional pedagogue-student paradigm and provides an alternative approach to teaching about HIV prevention and awareness.

  19. Towards Cache-Enabled, Order-Aware, Ontology-Based Stream Reasoning Framework

    2016-08-16

    While streaming data have become increasingly more popular in business and research communities, semantic models and processing software for streaming data have not kept pace. Traditional semantic solutions have not addressed transient data streams. Semantic web languages (e.g., RDF, OWL) have typically addressed static data settings and linked data approaches have predominantly addressed static or growing data repositories. Streaming data settings have some fundamental differences; in particular, data are consumed on the fly and data may expire. Stream reasoning, a combination of stream processing and semantic reasoning, has emerged with the vision of providing "smart" processing of streaming data. C-SPARQL is a prominent stream reasoning system that handles semantic (RDF) data streams. Many stream reasoning systems including C-SPARQL use a sliding window and use data arrival time to evict data. For data streams that include expiration times, a simple arrival time scheme is inadequate if the window size does not match the expiration period. In this paper, we propose a cache-enabled, order-aware, ontology-based stream reasoning framework. This framework consumes RDF streams with expiration timestamps assigned by the streaming source. Our framework utilizes both arrival and expiration timestamps in its cache eviction policies. In addition, we introduce the notion of "semantic importance" which aims to address the relevance of data to the expected reasoning, thus enabling the eviction algorithms to be more context- and reasoning-aware when choosing what data to maintain for question answering. We evaluate this framework by implementing three different prototypes and utilizing five metrics. The trade-offs of deploying the proposed framework are also discussed.

  1. RPD-based Hypothesis Reasoning for Cyber Situation Awareness

    Science.gov (United States)

    Yen, John; McNeese, Michael; Mullen, Tracy; Hall, David; Fan, Xiaocong; Liu, Peng

    Intelligence workers such as analysts, commanders, and soldiers often need a hypothesis reasoning framework to gain improved situation awareness of the highly dynamic cyber space. The development of such a framework requires the integration of interdisciplinary techniques, including supports for distributed cognition (human-in-the-loop hypothesis generation), supports for team collaboration (identification of information for hypothesis evaluation), and supports for resource-constrained information collection (hypotheses competing for information collection resources). We here describe a cognitively-inspired framework that is built upon Klein’s recognition-primed decision model and integrates the three components of Endsley’s situation awareness model. The framework naturally connects the logic world of tools for cyber situation awareness with the mental world of human analysts, enabling the perception, comprehension, and prediction of cyber situations for better prevention, survival, and response to cyber attacks by adapting missions at the operational, tactical, and strategic levels.

    The red-eared slider turtle (Trachemys scripta elegans) is native to portions of the United States of America (USA) and adjacent northeastern Mexico. The bright and colorful hatchlings have long been popular as pets globally but numerous individuals have been released into the wild establishing populations in areas well outside their native range. As a result, slider turtles are now introduced worldwide on all continents, with the exception of Antarctica, and many temperate and tropical islands, including Japan. They are very successful at establishing breeding populations in a variety of habitats, even those in proximity to human development. Once established in large populations, they compete with native turtle species sometimes to the detriment of the latter. Tin toy turtles were popular in Japan for decades, and they were an important export item after World War II. From the 1920s to the 1950s, prior to the widespread establishment of slider populations in Japan, the toys were characterized by muted earth-tone colors representative of native species of Japanese turtles. After the 1950s, toy turtles exhibited brighter combinations of yellow, red and green more typical of slider turtles. This transition may reflect demand for more colorful toys by importing countries like the USA. Alternatively, the change was coincident with the importation of large numbers of colorful slider turtles to Japan via the pet trade and their subsequent establishment and numerical dominance in Japanese wetlands. This switch in toy turtle colors may reflect a cultural transition in awareness of what constitutes the appearance of a typical turtle in Japan. Sliders appear to have been accepted by Japanese consumers as a new cultural norm in the appearance of turtles, a case of art imitating life.

    2010-07-01

    Reprojection is of interest in several applications such as iterative tomographic reconstruction, dose-calculation in radiotherapy and 3D-display volume-rendering. All numerical implementations of reprojection result in varying degrees of errors. Popular reprojection methods were compared using 128×128 2D-noiseless-numerical uniform-disk and Shepp-Logan phantoms to evaluate errors in external-border, interior and overall regions of the reprojected sinogram, in order to investigate a new method for increasing their accuracy on all regions. Root mean squared errors (RMSE) (with calculated projection as reference) were used. No method gives the least errors in all regions. Smoothing projectors decrease noise but introduce important errors in the border region, whereas other projectors increase errors inside the reprojected sinogram. The overall-error is a trade-off between interior and border errors. The conventional ray-driven (R1) and the bilinear-interpolated pixel driven with 5×5 sub-pixels (L5) provide the highest accuracy for border and interior regions, respectively. These results motivate the implementation of a new reprojection method that uses R1 to project pixels near borders in the sinogram and L5 for the others. Feature borders were localized using the spatial derivatives of sinogram count profile. This method provides the least errors for all regions. The performance of the new method was investigated on iterative reconstruction tasks with MLEM. Results show that the new method can promise more accuracy in terms of RMSE and aliasing reduction of the reconstructed images.

    2017-01-01

    Full Text Available The fifth generation mobile network, or 5G, moves towards bringing solutions to deploying faster networks, with hundreds of thousands of simultaneous connections and massive data transfer. For this purpose, several emerging technologies are implemented, resulting in virtualization and self-organization of most of their components, which raises important challenges related to safety. In order to contribute to their resolution, this paper proposes a novel architecture for incident management on 5G. The approach combines the conventional risk management schemes with the Endsley Situational Awareness model, thus improving effectiveness in different aspects, among them the ability to adapt to complex and dynamical monitoring environments, and countermeasure tracking or the role of context when decision-making. The proposal takes into account all layers for information processing in 5G mobile networks, ranging from infrastructure to the actuators responsible for deploying corrective measures.

    Full Text Available Japanese popular culture has arrived on American college campuses as never before. Student interest in Japanese manga (comic books, anime (animated films and television shows, and video games drives much of the enrollment in Japanese courses and Japanese majors and minors. In response to student interest, as well as the establishment of popular culture as a topic of serious academic scholarship, the demand for courses on Japanese popular culture has never been higher. Yet the number of scholars specializing in the study of popular culture is still relatively small. This can potentially create problems, as faculty teach outside their expertise, and perhaps face an uncomfortable situation in which the students know more about the topic than the professor. In this article, I will offer some suggestions and advice for faculty creating a popular culture course for the first time, based on my experiences teaching undergraduates at the University of Notre Dame. The course I developed reflects my background in Japanese literature and film, and is but one example of many possible approaches to the topic. The sample syllabus and list of resources at the end of this article provide citations for all text and media sources mentioned.

    Study objectives were to measure awareness of general antitobacco messages in LGBT-focused and general media outlets among LGBT (lesbian, gay, bisexual, and transgender) individuals and to examine associations between sociodemographic characteristics and awareness levels. Data were based on cross-sectional survey data from a racially diverse sample of participants (N = 726). Participants were primarily male (69.3%), with smaller percentages of female (21.8%) and transgender (8.9%). The median age was 31 years. A higher proportion of participants reported awareness of antitobacco messages in general media outlets compared to LGBT-specific media outlets. Awareness of antitobacco messages in general media was positively associated with current smoking and negatively associated with female gender and Latino ethnicity. Awareness of antitobacco messages in LGBT media was positively associated with younger age, current smoking, frequent reading of LGBT newspapers or magazines, and frequent attendance at LGBT bars and negatively associated with Latino ethnicity. Despite frequent readership, awareness of antitobacco messages in LGBT newspapers/magazines was quite low. We speculate that low awareness is related to the absence of antitobacco messages in LGBT-related media. LGBT-specific media outlets provide an important opportunity for future antitobacco campaigns. © 2014 Society for Public Health Education.

    2018-03-01

    As the speed of optical access networks soars with ever increasing multiple services, the service-supporting ability of optical access networks suffers greatly from the shortage of service awareness. Aiming to solve this problem, a hierarchy Bayesian model based services awareness mechanism is proposed for high-speed optical access networks. This approach builds a so-called hierarchy Bayesian model, according to the structure of typical optical access networks. Moreover, the proposed scheme is able to conduct simple services awareness operation in each optical network unit (ONU) and to perform complex services awareness from the whole view of system in optical line terminal (OLT). Simulation results show that the proposed scheme is able to achieve better quality of services (QoS), in terms of packet loss rate and time delay.

This study aimed to determine the knowledge, awareness, and attitude of dentistry students towards evidence-based dentistry. Methods In this cross-sectional study, all dentistry students who were studying in their sixth semester and higher in the Kerman School of Dentistry (n = 73) were studied. The data were analyzed using SPSS version 17 and the independent-samples t-tests and the ANOVA test. Results The means of the students’ knowledge, awareness, and attitude scores were 29.2 ± 10.8, 29.9 ± 8.12 and 44.5 ± 5.3, respectively. Among demographic variables, only the number of semesters showed a significant difference with knowledge, awareness, and attitude of dentistry students toward evidence-based dentistry (p = 0.001). Conclusion According to the results of this study, knowledge and awareness of dentistry students at Kerman University of Medical Sciences towards evidence-based dentistry were average and have a neutral attitude. Thus, providing necessary training in this regard will cause promoting the knowledge, awareness, and improved attitudes of dentistry students. PMID:27382446

  20. Dissociable Electroencephalograph Correlates of Visual Awareness and Feature-Based Attention

    Directory of Open Access Journals (Sweden)

    Yifan Chen

    2017-11-01

    Full Text Available Background: The relationship between awareness and attention is complex and controversial. A growing body of literature has shown that the neural bases of consciousness and endogenous attention (voluntary attention are independent. The important role of exogenous attention (reflexive attention on conscious experience has been noted in several studies. However, exogenous attention can also modulate subliminal processing, suggesting independence between the two processes. The question of whether visual awareness and exogenous attention rely on independent mechanisms under certain circumstances remains unanswered.Methods: In the current study, electroencephalograph recordings were conducted using 64 channels from 16 subjects while subjects attempted to detect faint speed changes of colored rotating dots. Awareness and attention were manipulated throughout trials in order to test whether exogenous attention and visual awareness rely on independent mechanisms.Results: Neural activity related to consciousness was recorded in the following cue-locked time-windows (event related potential, cluster- based permutation test: 0–50, 150–200, and 750–800 ms. With a more liberal threshold, the inferior occipital lobe was found to be the source of awareness-related activity in the 0–50 ms range. In the later 150–200 ms range, activity in the fusiform and post-central gyrus was related to awareness. Awareness-related activation in the later 750–800 ms range was more widely distributed. This awareness-related activation pattern was quite different from that of attention. Attention-related neural activity was emphasized in the 750–800 ms time window and the main source of attention-related activity was localized to the right angular gyrus. These results suggest that exogenous attention and visual consciousness correspond to different and relatively independent neural mechanisms and are distinct processes under certain conditions.

Here we show that protein-equivalent plant based alternatives to the beef portion of the mean American diet are readily devisible, and offer mostly improved nutritional profile considering the full lipid profile, key vitamins, minerals, and micronutrients. We then show that replacement diets require on average only 10% of land, 4% of greenhouse gas (GHG) emissions, and 6% of reactive nitrogen (Nr) compared to what the replaced beef diet requires. Applied to 320 million Americans, the beef-to-plant shift can save 91 million cropland acres (and 770 million rangeland acres), 278 million metric ton CO2e, and 3.7 million metric ton Nr annually. These nationwide savings are 27%, 4%, and 32% of the respective national environmental burdens.

  6. [Popular education in health and nutrition: literature review].

    1993-01-01

    This literature review of popular education in health and nutrition is intended to provide the necessary theoretical framework for proposals and programs for human resource development in food and nutrition. The work contains a summary of the objectives, purposes, and methodology of popular education in general, a discussion of applications of popular education techniques to health and nutrition education, and a description of some projects based on popular education. Popular education was developed in Latin America by Paulo Freire and others as a response to political domination. Its basic objective was to make the oppressed masses aware of their condition and able to struggle for the transformation of society. Popular education views community participation, development of consciousness, and integration with social and economic activity as fundamental attributes. Participation should be developed through community organizations and should continue for the duration of the educational intervention. The right of all persons to participate in a plane of equality should be recognized. Community or popular education should be conceived as a process of permanent education that will continue throughout the lifetime of individuals and groups. Popular education is directed toward population sectors excluded from participation in employment, family, community, mass communications, education, and leisure activities. Such population sectors are concentrated in the urban periphery and in rural areas. Abandonment of traditional educational techniques and assumption of an active role by community members are elements in development of the methodology of popular education. Steps in the methodology include investigation of possible themes, selection of themes to serve as points of departure, definition of the problem, and action programs. Popular education in nutrition and health begins by asking what problems need to be remedied. The entire process of training and education in

    2002-04-01

    Popular Iconic Metaphor is added to the cognitive linguistic lexicon of figurative language. Popular Iconic Metaphors employ real or fictional celebrities of popular culture as source domains in figurative discourse. Some borders of Popular Iconic Metaphor are identified, and Elvis Presley is offered as a prototype example of a popular iconic source domain, due to his ubiquity in American popular culture, which affords his figurative usage in ways consistent with decision heuristics in everyday life. Further study of Popular Iconic Metaphors may serve to illuminate how figurative expressions emerge in their localized contexts, structure conduct and experience, and affect mediation of cultural and personal meanings.

    2014-01-01

    Wireless sensor network (WSN) typically has energy consumption restriction. Designing energy-aware routing protocol can significantly reduce energy consumption in WSNs. Energy-aware routing protocols can be classified into two categories, energy savers and energy balancers. Energy saving protocols are used to minimize the overall energy consumed by a WSN, while energy balancing protocols attempt to efficiently distribute the consumption of energy throughout the network. In general terms, energy saving protocols are not necessarily good at balancing energy consumption and energy balancing protocols are not always good at reducing energy consumption. In this paper, we propose an energy-aware routing protocol (ERP) for query-based applications in WSNs, which offers a good trade-off between traditional energy balancing and energy saving objectives and supports a soft real time packet delivery. This is achieved by means of fuzzy sets and learning automata techniques along with zonal broadcasting to decrease total energy consumption.

    Full Text Available As part of “intelligence,” the “awareness” is the state or ability to perceive, feel, or be mindful of events, objects, or sensory patterns: in other words, to be conscious of the surrounding environment and its interactions. Inspired by early-ages human skills developments and especially by early-ages awareness maturation, the present paper accosts the robots intelligence from a different slant directing the attention to combining both “cognitive” and “perceptual” abilities. Within such a slant, the machine (robot shrewdness is constructed on the basis of a multilevel cognitive concept attempting to handle complex artificial behaviors. The intended complex behavior is the autonomous discovering of objects by robot exploring an unknown environment: in other words, proffering the robot autonomy and awareness in and about unknown backdrop.

    Medication nonadherence is a widely recognized problem that leads to adverse outcomes and increased health care costs. Reasons for medication nonadherence are multifactorial, and patient awareness of the salience of medication adherence is critical. The purpose of this research was to assess the impact of a pharmacist-led, web-based video presentation in increasing patients' awareness of the importance of medication adherence. Patients aged 35 years and above, taking at least 1 chronic prescription medication were included in the study (n = 166). Patients completed a pre-survey, watched a pharmacist-led web-based video presentation educating them on the importance of medication adherence, then completed a 1-month follow-up survey. The primary outcome was measurement of change in patients' awareness of the importance of medication adherence. Results indicated a statistically significant increase in the primary outcome of increasing awareness of the importance of medication adherence. More patients in the follow-up survey indicated that it was important for their health to take their medications around the same time daily (P = 0.002), and more patients identified that their family will be impacted as a result of their medication nonadherence (P = 0.001) as compared to the pre-survey. More patients in the follow-up survey reported that they expected to experience fewer emergency room visits (P = 0.0001) and anticipated that they would get more time to spend with friends and family (P = 0.0039) as benefits of taking medications as prescribed. A pharmacist-led web-based video presentation may be a low-cost intervention to increase patients' awareness of the importance of medication adherence. Copyright © 2015 Elsevier Inc.

    Full Text Available Smart reconfiguration of a dynamic networking environment is offered by the central control of Software-Defined Networking (SDN. Centralized SDN-based management architectures are capable of retrieving global topology intelligence and decoupling the forwarding plane from the control plane. Routing protocols developed for conventional Wireless Sensor Networks (WSNs utilize limited iterative reconfiguration methods to optimize environmental reporting. However, the challenging networking scenarios of WSNs involve a performance overhead due to constant periodic iterative reconfigurations. In this paper, we propose the SDN-based Application-aware Centralized adaptive Flow Iterative Reconfiguring (SACFIR routing protocol with the centralized SDN iterative solver controller to maintain the load-balancing between flow reconfigurations and flow allocation cost. The proposed SACFIR’s routing protocol offers a unique iterative path-selection algorithm, which initially computes suitable clustering based on residual resources at the control layer and then implements application-aware threshold-based multi-hop report transmissions on the forwarding plane. The operation of the SACFIR algorithm is centrally supervised by the SDN controller residing at the Base Station (BS. This paper extends SACFIR to SDN-based Application-aware Main-value Centralized adaptive Flow Iterative Reconfiguring (SAMCFIR to establish both proactive and reactive reporting. The SAMCFIR transmission phase enables sensor nodes to trigger direct transmissions for main-value reports, while in the case of SACFIR, all reports follow computed routes. Our SDN-enabled proposed models adjust the reconfiguration period according to the traffic burden on sensor nodes, which results in heterogeneity awareness, load-balancing and application-specific reconfigurations of WSNs. Extensive experimental simulation-based results show that SACFIR and SAMCFIR yield the maximum scalability, network lifetime

    2018-03-01

    Full Text Available The purpose of this paper is to compare the degree of uncertainty of the water scarcity footprint using the Monte Carlo statistical method and block bootstrap method. Using the hydrological data of a water drainage basin in Korea, characterization factors based on the available water remaining (AWARE model were obtained. The uncertainties of the water scarcity footprint considering temporal variations in paddy rice production in Korea were estimated. The block bootstrap method gave five-times smaller percentage uncertainty values of the model output compared to that of the two different Monte Carlo statistical method scenarios. Incorrect estimation of the probability distribution of the AWARE characterization factor model is what causes the higher uncertainty in the water scarcity footprint value calculated by the Monte Carlo statistical method in this study. This is because AWARE characterization factor values partly follows discrete distribution with extreme value on one side. Therefore, this study suggests that the block bootstrap method is a better choice in analyzing uncertainty compared to the Monte Carlo statistical method when using the AWARE model to quantify the water scarcity footprint.

    To evaluate the status of ethical awareness of medical journals in China.
 We surveyed editorial awareness based on 88 medical journals by using self-made questionnaire. Five aspects were selected by literature and systematic analysis: Instruction for authors, the first review stage, the peer-review stage, the editing stage, as well as education and training, which covered 11 indexes in the system. Weight values of indexes were gained by scoring of senior editors, and analytic hierarchy process, TOPSIS method, and weight rank-sun ratio were used to evaluate the status of editorial awareness.
 Of the 88 biomedical journals, 56 (63.6%) had no ethical requirement in the instruction for authors in 2010, 14 (15.9%) were at high level of ethical awareness, 45 (51.1%) were at medium level, and 29(33.0%) were at low level. There were significant differences in the scores of instruction for authors and peer-review stage among the journals administrated by different authorities (H(C)=10.175, H=7.305, Pjournals covered by different databases (H(C)=11.951, 7.661, 6.146, or 8.085, Pjournals (H(C)=6.109, Pjournals in China should be improved. Comprehensive approach is more reliable and practical than that of single approach.

  6. An Awareness-Based Learning Model to Deal with Service Collaboration in Cloud Computing

    Science.gov (United States)

    Paletta, Mauricio; Herrero, Pilar

    Cloud computing addresses the use of scalable and often virtualized resources. It is based on service-level agreements that provide external users with services under request. Cloud computing is still evolving. New specific collaboration models among service providers are needed for enabling effective service collaboration, allowing the process of serving consumers to be more efficient. This paper presents AMBAR-C, an adaptation of AMBAR (Awareness-based learning Model for distriButive collAborative enviRonment) designed to allow nodes in a distributed environment to accomplish an effective collaboration among service providers in a "cloud" by means of a multi-agent architecture in which agents are aware of its surroundings throughout a parametrical and flexible use of this information. As occurs in AMBAR, AMBAR-C makes use of heuristic strategies to improve effectiveness and efficiency in collaborations of these particular environments.

  7. Interest Aware Location-Based Recommender System Using Geo-Tagged Social Media

    2016-12-01

    Full Text Available Advances in location acquisition and mobile technologies led to the addition of the location dimension to Social Networks (SNs and to the emergence of a newer class called Location-Based Social Networks (LBSNs. While LBSNs are richer in their model and functions than SNs, they fail so far to attract as many users as SNs. On the other hand, SNs have large amounts of geo-tagged media that are under-utilized. In this paper, we propose an Interest-Aware Location-Based Recommender system (IALBR, which combines the advantages of both LBSNs and SNs, in order to provide interest-aware location-based recommendations. This recommender system is proposed as an extension to LBSNs. It is novel in: (1 utilizing the geo-content in both LBSNs and SNs; (2 ranking the recommendations based on a novel scoring method that maps to the user interests. It also works for passive users who are not active content contributors to the LBSN. This feature is critical to increase the number of LBSN users. Moreover, it helps with reducing the cold start problem, which is a common problem facing the new users of recommender systems who get random unsatisfying recommendations. This is due to the lack of user interest awareness, which is reliant on user history in most of the recommenders. We evaluated our system with a large-scale real dataset collected from foursquare with respect to precision, recall and the f-measure. We also compared the results with a ground truth system using metrics like the normalized discounted cumulative gain and the mean absolute error. The results confirm that the proposed IALBR generates more efficient recommendations than baselines in terms of interest awareness.

    Online awareness is the ability to self-monitor, identify and self-correct errors while engaged in an activity. Current assessments of online awareness involve observing and classifying error behaviour during structured, uniform tasks. However, during rehabilitation, practitioners typically work towards improving performance in individually meaningful tasks unique to the client. This article presents a metacognitive, task analytic approach to assessing online awareness involving observation and classification of errors during meaningful occupations determined after client-centred goal setting with two male clients with severe traumatic brain injury (aged 22 and 23). Study aims were to describe the approach, evaluate its feasibility and determine inter-rater agreement for error detection and error categorisation by two experienced occupational therapists. Furthermore, the error profiles and cognitive impairments of the participants on standardised neuropsychological assessment were examined to explore the validity of the assessment. Individualised assessment tasks included snack preparation, budgeting, timetabling, hot-drink preparation and use of a computer program, which were administered repeatedly over two to three months and audio-visual recordings taken. Independent ratings of two trained occupational therapists were compared using exact percent agreement. Overall agreement about errors was 76%, for which there was 65% agreement about error categorisation and 100% agreement about error correction. There was fair inter-rater agreement between two trained occupational therapists of error behaviour and error correction when using the described occupation-based approach to assessing online awareness. This approach has promise, particularly when combined with standardised, neuropsychological assessments, for providing an in-depth understanding of error behaviour and awareness of errors during meaningful occupations. © 2016 Occupational Therapy Australia.

    Full Text Available Background: Gifted individuals have exclusive personality traits and need various experiences to achieve more information about themselves and their ability into developmental process from giftedness to talent. Also, they can increase mental experiences and obtain greater self- actualization with recognition of the level of challenges, values and their personality traits. The aim of this study was to assess the relationship between personality traits, self-awareness and self-actualization dimensions. Methods: This descriptive study was conducted in Shiraz city among 239 gifted students from high schools during 2013. The Big Five Personality Questionnaire (BFPQ, Self-Consciousness Scale (SCS and Measure of Actualization of Potential (MAP were used to gather the data. Validity and reliability of these tools were acceptable. Data were analyzed by regression test using SPSS v19 statistic software. Results: The finding showed that agreeableness (r=0.34 and conscientiousness (r=0.41 factors (from five factors of personality had a positive relationship and neuroticism (r=-0.21 had a correlation with self-actualization negatively. Moreover, the privative self-awareness (r=0.41 and public self-awareness (r=0.15 showed a positive correlation and social anxiety revealed a significant negative relationship (r=-0.27 with general selfactualization. On the other hand, privative self-awareness and agreeableness predicted that 23% of the scores belong to openness to experience dimension (self–actualization positively. In addition, conscientiousness and privative self-awareness predicted self-reference dimension positively, and neuroticism predicted it negatively. These variables determine 40% of the scores of self reference dimension. Also, conscientiousness, agreeableness and privative self-awareness predicted that 36% of the scores belong to general self-actualization. Conclusion: Based on our study results, conscientiousness and agreeableness factors

    There are number of Non-Governmental Organisations (NGOs) in South Africa that use sport as a tool to respond to Human Immunodeficiency Virus/Acquired Immunodeficiency Syndrome (HIV/AIDS), however, little is reported about the outcomes and impact of these programmes. The aim of this study is to contribute to a generic monitoring and evaluation framework by improving the options for the use of outcome indicators of sport-based HIV/AIDS awareness programmes of selected NGOs in South Africa. A qualitative method study was carried out with seven employees of five selected NGOs that integrate sport to deliver HIV/AIDS programmes in South Africa. The study further involved six specialists/experts involved in the field of HIV/AIDS and an official from Sport Recreation South Africa (SRSA). Multiple data collection instruments including desktop review, narrative systematic review, document analysis, one-on-one interviews and focus group interview were used to collect information on outcomes and indicators for sport-based HIV/AIDS awareness programmes. The information was classified according to the determinants of HIV/AIDS. The overall findings revealed that the sport-based HIV/AIDS awareness programmes of five selected NGOs examined in this study focus on similar HIV prevention messages within the key priorities highlighted in the current National Strategic Plan for HIV/AIDS, STIs and TB of South Africa. However, monitoring and evaluating outcomes of sport-based HIV/AIDS programmes of the selected NGOs remains a challenge. A need exists for the improvement of the outcome statements and indicators for their sport-based HIV/AIDS awareness programmes. This study proposed a total of 51 generic outcome indicators focusing on measuring change in the knowledge of HIV/AIDS and change in attitude and intention towards HIV risk behaviours. In addition, this study further proposed a total of eight generic outcome indicators to measure predictors of HIV risk behaviour. The selected

    2018-01-01

    Full Text Available In the last years, we have witnessed the introduction of the Internet of Things (IoT as an integral part of the Internet with billions of interconnected and addressable everyday objects. On one hand, these objects generate a massive volume of data that can be exploited to gain useful insights into our day-to-day needs. On the other hand, context-aware recommender systems (CARSs are intelligent systems that assist users to make service consumption choices that satisfy their preferences based on their contextual situations. However, one of the key challenges facing the development and deployment of CARSs is the lack of functionality for providing dynamic and reliable context information required by the recommendation decision process. Thus, data obtained from IoT objects and other sources can be exploited to build CARSs that satisfy users’ preferences, improve quality of experience, and boost recommendation accuracy. This article describes various components of a conceptual IoT-based framework for context-aware personalized recommendations. The framework addresses the weakness whereby CARSs rely on static and limited contexts from user’s mobile phone by providing additional components for reliable and dynamic context information, using IoT context sources. The core of the framework consists of a context classification and reasoning management and a dynamic user profile model, incorporating trust to improve the accuracy of context-aware personalized recommendations. Experimental evaluations show that incorporating context and trust into personalized recommendation process can improve accuracy.

  12. Social Content Recommendation Based on Spatial-Temporal Aware Diffusion Modeling in Social Networks

    2016-09-01

    Full Text Available User interactions in online social networks (OSNs enable the spread of information and enhance the information dissemination process, but at the same time they exacerbate the information overload problem. In this paper, we propose a social content recommendation method based on spatial-temporal aware controlled information diffusion modeling in OSNs. Users interact more frequently when they are close to each other geographically, have similar behaviors, and fall into similar demographic categories. Considering these facts, we propose multicriteria-based social ties relationship and temporal-aware probabilistic information diffusion modeling for controlled information spread maximization in OSNs. The proposed social ties relationship modeling takes into account user spatial information, content trust, opinion similarity, and demographics. We suggest a ranking algorithm that considers the user ties strength with friends and friends-of-friends to rank users in OSNs and select highly influential injection nodes. These nodes are able to improve social content recommendations, minimize information diffusion time, and maximize information spread. Furthermore, the proposed temporal-aware probabilistic diffusion process categorizes the nodes and diffuses the recommended content to only those users who are highly influential and can enhance information dissemination. The experimental results show the effectiveness of the proposed scheme.

    2011-01-01

    This paper reviews the conceptual foundation of mindfulness-based eating awareness training (MB-EAT). It provides an overview of key therapeutic components as well as a brief review of current research. MB-EAT is a group intervention that was developed for treatment of binge eating disorder (BED) and related issues. BED is marked by emotional, behavioral and physiological disregulation in relation to food intake and self-identity. MB-EAT involves training in mindfulness meditation and guided mindfulness practices that are designed to address the core issues of BED: controlling responses to varying emotional states; making conscious food choices; developing an awareness of hunger and satiety cues; and cultivating self-acceptance. Evidence to date supports the value of MB-EAT in decreasing binge episodes, improving one's sense of self-control with regard to eating, and diminishing depressive symptoms.

    2011-01-01

    Research with Native Americans has identified connectedness as a culturally-based protective factor against substance abuse and suicide. Connectedness refers to the interrelated welfare of the individual, one’s family, one’s community, and the natural environment. We developed an 18-item quantitative assessment of awareness of connectedness and tested it with 284 Alaska Native youth. Evaluation with confirmatory factor analysis and item response theory identified a 12-item subset that functions satisfactorily in a second-order, four-factor model. The proposed Awareness of Connectedness Scale displays good convergent and discriminant validity and correlates positively with hypothesized protective factors such as reasons for living and communal mastery. The measure has utility in the study of culture-specific protective factors and as an outcomes measure for behavioral health programs with Native American youth. PMID:21988583

    Full Text Available Users planning a trip to a given destination often search for the most appropriate points of interest location, this being a non-straightforward task as the range of information available is very large and not very well structured. The research presented by this paper introduces a context-aware tourism recommender system that overcomes the information overload problem by providing personalized recommendations based on the user’s preferences. It also incorporates contextual information to improve the recommendation process. As previous context-aware tourism recommender systems suffer from a lack of formal definition to represent contextual information and user’s preferences, the proposed system is enhanced using an ontology approach. We also apply a spreading activation technique to contextualize user preferences and learn the user profile dynamically according to the user’s feedback. The proposed method assigns more effect in the spreading process for nodes which their preference values are assigned directly by the user. The results show the overall performance of the proposed context-aware tourism recommender systems by an experimental application to the city of Tehran.

    In developing nations like India awareness and education about dental implants as a treatment modality is still scanty. The study was conducted to determine the awareness, knowledge, and attitude of patients toward dental implants as a treatment modality among the general population and to assess the influence of personality characteristics on accepting dental implants as a treatment modality in general and as well as treatment group. A structured questionnaire-based survey was conducted on 500 randomly selected participants attending the outpatient department. The study was conducted in 2 parts. In the first part of the study, level of awareness, knowledge, and attitude was assessed. In the second part of the study, interactive educational sessions using audiovisual aids were conducted following which a retest was conducted. The participants who agreed to undergo implant treatment were followed up to assess their change in attitude towards dental implants posttreatment. Thus pain, anxiety, functional, and esthetic benefits were measured using visual analog scale. They were further followed up for 1 year to reassess awareness, knowledge, and attitude towards dental implants. A total of 450 individuals completed the questionnaires. Only 106 individuals agreed to participate in the educational sessions and 83 individuals took the retest. Out of these, only 39 individuals chose implants as a treatment option. A significant improvement in the level of information, subjective and objective need for information, was noted after 1 year. In this study, a severe deficit in level of information, subjective and objective need for information towards, dental implants as a treatment modality was noted. In the treatment group, a significant improvement in perception of dental implant as a treatment modality suggests that professionally imparted knowledge can bring about a change in the attitude.

    Situation awareness has been defined as the perception of the elements in the environment within volumes of time and space, the comprehension of their meaning, and the projection of their status in the near future. Intensivists often make time-sensitive critical decisions, and loss of situation awareness can lead to errors. It has been shown that simulation-based training is superior to lecture-based training for some critical scenarios. Because the methods of training to improve situation awareness have not been well studied in the medical field, we compared the impact of simulation vs. lecture training using the Situation Awareness Global Assessment Technique (SAGAT) score. To identify an effective method for teaching situation awareness. We randomly assigned 17 critical care fellows to simulation vs. lecture training. Training consisted of eight cases on airway management, including topics such as elevated intracranial pressure, difficult airway, arrhythmia, and shock. During the testing scenario, at random times between 4 and 6 minutes into the simulation, the scenario was frozen, and the screens were blanked. Respondents then completed the 28 questions on the SAGAT scale. Sample items were categorized as Perception, Projection, and Comprehension of the situation. Results were analyzed using SPSS Version 21. Eight fellows from the simulation group and nine from the lecture group underwent simulation testing. Sixty-four SAGAT scores were recorded for the simulation group and 48 scores were recorded for the lecture group. The mean simulation vs. lecture group SAGAT score was 64.3 ± 10.1 (SD) vs. 59.7 ± 10.8 (SD) (P = 0.02). There was also a difference in the median Perception ability between the simulation vs. lecture groups (61.1 vs. 55.5, P = 0.01). There was no difference in the median Projection and Comprehension scores between the two groups (50.0 vs. 50.0, P = 0.92, and 83.3 vs. 83.3, P = 0.27). We found a significant, albeit

    Full Text Available Sensor-equipped mobile devices have allowed users to participate in various social networking services. We focus on proximity-based mobile social networking environments where users can share information obtained from different places via their mobile devices when they are in proximity. Since people are more likely to share information if they can benefit from the sharing or if they think the information is of interest to others, there might exist community structures where users who share information more often are grouped together. Communities in proximity-based mobile networks represent social groups where connections are built when people are in proximity. We consider information influence (i.e., specify who shares information with whom as the connection and the space and time related to the shared information as the contexts. To model the potential information influences, we construct an influence graph by integrating the space and time contexts into the proximity-based contacts of mobile users. Further, we propose a two-phase strategy to detect and track context-aware communities based on the influence graph and show how the context-aware community structure improves the performance of two types of mobile social applications.

    Original pictures installed in the 1st and 2nd generation type central control panels (CCP) and new 'Awarable and Complex' pictures were made on personal computers and evaluated. A total 18 of actual plant operators (M=32.3, SD=10.5 years old) participated in the evaluation. The operators rated the new CRT pictures highly. The response times using the new CRT pictures were shorter than those by the original pictures. Both results suggested that the CRT picture design guidelines based on the operators' plant images were effective for improving their performance. (author)

    attempt to efficiently distribute the consumption of energy throughout the network. In general terms, energy saving protocols are not necessarily good at balancing energy consumption and energy balancing protocols are not always good at reducing energy consumption. In this paper, we propose an energy-aware routing protocol (ERP for query-based applications in WSNs, which offers a good trade-off between traditional energy balancing and energy saving objectives and supports a soft real time packet delivery. This is achieved by means of fuzzy sets and learning automata techniques along with zonal broadcasting to decrease total energy consumption.

Material and Methodology The following study is a home based vision screening program using IPAD which uses the basic tests like visual acuity color vision contrast sensitivity and amsler tests for checking the basic functions of the eye. The study was performed in many societies moving from one place to another using IPAD as a tool. Reliability of ipad was checked a pilot study on 25 subjects visual acuity colour vision and contrast sensitivity was taken on both ipad and Original chart like snellen ishihara and pellirobson and compared in which the results and the accuracy were same. The study also contains questionnaire on the awareness and education about eye health. The subjects included in the study were an age group of 10 to 70. Subjects like infants and blind were not included in the study. Results During the study it was observed that there is no significant difference in testing of visual acuity between ipad and Snellen standard chart. The subjects responded actively towards screening and that home vision screening can be possible. During the study it was found that 40 subjects out of 100 needed further detailed check-up and were referred in Rotary eye hospital hospital but only 3 out of 40 came for it. This shows that they are less aware and education about their eye health. Software used in IPAD were visual acuity color vision contrast sensitivity and amsler tests A questionnaire was also asked which indicated less awareness among the common people.

    Recommender System is software that is able to provide personalized recommendation suits users’ needs. Recommender System has been widely implemented in various domains, including tourism. One approach that can be done for more personalized recommendations is the use of contextual information. This paper proposes a context aware recommender based ontology system in the tourism domain. The system is capable of recommending tourist destinations by using user preferences of the categories of tourism and contextual information such as user locations, weather around tourist destinations and close time of destination. Based on the evaluation, the system has accuracy of of 0.94 (item recommendation precision evaluated by expert) and 0.58 (implicitly from system-end user interaction). Based on the evaluation of user satisfaction, the system provides a satisfaction level of more than 0.7 (scale 0 to 1) for speed factors for providing liked recommendations (PE), informative description of recommendations (INF) and user trust (TR).

    Traditional recommender algorithms usually employ the early and recent records indiscriminately, which overlooks the change of user interests over time. In this paper, we show that the interests of a user remain stable in a short-term interval and drift during a long-term period. Based on this observation, we propose a time-aware diffusion-based (TaDb) recommender algorithm, which assigns different temporal weights to the leading links existing before the target user's collection and the following links appearing after that in the diffusion process. Experiments on four real datasets, Netflix, MovieLens, FriendFeed and Delicious show that TaDb algorithm significantly improves the prediction accuracy compared with the algorithms not considering temporal effects.

    As the development of Web 2.0, the social media like microblog, blogs and social network have supplied a bunch of information with locations (Volunteered Geographical Information, VGI).Recent years many cases have shown that, if disaster happened, the cyber citizens will get together very quickly and share the disaster information, this results a bunch of volunteered geographical information about disaster situation which is very valuable for disaster response if this VGIs are used efficiently and properly. This project will take typhoon disaster as case study. In this paper, we study the relations between weibo messages and the real typhoon situation, we proposed an analysis framework for mine the relations between weibo messages distribution and physical space. We found that the number of the weibo messages, key words frequency and spatial temporary distribution of the messages have strong relations with the disaster spread in the real world, and this research results can improve our disaster situation awareness in the future. The achievement of the study will give a method for typhoon disaster situation awareness based on VGI from the bottom up, and will locate the disaster spot and evolution quickly which is very important for disaster response and recover.

    Real-world data usually comprise features whose interpretation depends on some contextual information. Such contextual-sensitive features and patterns are of high interest to be discovered and analyzed in order to obtain the right meaning. This paper formulates the problem of mining context-aware association rules, which refers to the search for associations between itemsets such that the strength of their implication depends on a contextual feature. For the discovery of this type of associations, a model that restricts the search space and includes syntax constraints by means of a grammar-based genetic programming methodology is proposed. Grammars can be considered as a useful way of introducing subjective knowledge to the pattern mining process as they are highly related to the background knowledge of the user. The performance and usefulness of the proposed approach is examined by considering synthetically generated datasets. A posteriori analysis on different domains is also carried out to demonstrate the utility of this kind of associations. For example, in educational domains, it is essential to identify and understand contextual and context-sensitive factors that affect overall and individual student behavior and performance. The results of the experiments suggest that the approach is feasible and it automatically identifies interesting context-aware associations from real-world datasets.

    Ullah, Farman; Sarwar, Ghulam; Lee, Sungchang

    2014-01-01

    This paper presents a recommender system for N-screen services in which users have multiple devices with different capabilities. In N-screen services, a user can use various devices in different locations and time and can change a device while the service is running. N-screen aware recommendation seeks to improve the user experience with recommended content by considering the user N-screen device attributes such as screen resolution, media codec, remaining battery time, and access network and the user temporal usage pattern information that are not considered in existing recommender systems. For N-screen aware recommendation support, this work introduces a user device profile collaboration agent, manager, and N-screen control server to acquire and manage the user N-screen devices profile. Furthermore, a multicriteria hybrid framework is suggested that incorporates the N-screen devices information with user preferences and demographics. In addition, we propose an individual feature and subspace weight based clustering (IFSWC) to assign different weights to each subspace and each feature within a subspace in the hybrid framework. The proposed system improves the accuracy, precision, scalability, sparsity, and cold start issues. The simulation results demonstrate the effectiveness and prove the aforementioned statements.

    Reliable source to sink communication is the most important factor for an efficient routing protocol especially in domains of military, healthcare and disaster recovery applications. We present weighted energy aware multipath reliable routing (WEAMR), a novel energy aware multipath routing protocol which utilizes hotline-assisted routing to meet such requirements for mission critical applications. The protocol reduces the number of average hops from source to destination and provides unmatched reliability as compared to well known reactive ad hoc protocols i.e., AODV and AOMDV. Our protocol makes efficient use of network paths based on weighted cost calculation and intelligently selects the best possible paths for data transmissions. The path cost calculation considers end to end number of hops, latency and minimum energy node value in the path. In case of path failure path recalculation is done efficiently with minimum latency and control packets overhead. Our evaluation shows that our proposal provides better end-to-end delivery with less routing overhead and higher packet delivery success ratio compared to AODV and AOMDV. The use of multipath also increases overall life time of WSN network using optimum energy available paths between sender and receiver in WDNs.

    Management guidelines emphasise the importance of prompt therapeutic intervention for sepsis as well as stroke, both of which are common causes of death. Unfortunately, a rate-limiting step may be delayed presentation to the emergency department by patients themselves. The aim of this study was to assess public awareness of sepsis and stroke in Singapore. This was a population-based, structured telephone survey of adults in Singapore. There were 1067 completed surveys (response rate 50.3%). The survey population was mostly comparable with the actual Singapore population. Fifty-three respondents (5.0%) had heard of the term sepsis. Of these, 45 respondents (4.2%) could provide at least one accepted definition of sepsis, the commonest being that of an unspecified infection. Respondents mostly heard about sepsis from school, the Internet, and newspapers. On the other hand, 963 respondents (90.3%) had heard of the term stroke. Of these, 818 respondents (76.7%) could name at least one accepted warning sign of stroke, the commonest being that of numbness, while 806 respondents (75.5%) could name at least one accepted risk factor for stroke, the commonest being hypertension. Respondents mostly heard about stroke from television, newspapers, a relative, a friend, media (unspecified), and the Internet. Our findings reflect the differences in the public profile of sepsis versus stroke in Singapore. More concerted efforts involving healthcare professionals, medical societies, statutory boards, and the mass media are required to improve public awareness of these 2 conditions -especially sepsis.

    Full Text Available The Popular Legal Action is a constitutional remedy, which is originated from the necessity of improving the Defense of Public Interest as well as of the Public Administration Morality Act. This remedy is a clear manifestation of the citizens’ sovereignty. This legal measure entitles any citizen to obtain the invalidation of illegal administrative acts or contract that can cause damages to the Federal, State and Municipal Property, which includes public agencies and any private party entitled to handle public money. This study has the purpose of preserving the public interest through probity, efficiency and morality when handling public property. In addition, it includes the environmental protection and the State Properties. Its aim is the prevention and interruption of the illicit act with the consequent conviction of the defendants who must return the damaged property to its status quo ante. It is a legal enforcement act that puts the Public Administration Defense into effect, not taking into consideration any personal advantage from the author. Although this legal remedy is concerned with the population as a whole, who is the beneficiary of the possible nullification of the illicit act, it is clear that this citizen will have his/her constitutional right preserved. In short, this Popular Legal Action is a political right that each citizen can make use of, in order to supervise the Administrative legality as well as his/her right to participate in the State Policy.A ação popular constitui-se em remédio constitucional nascido da necessidade de melhorar a defesa do interesse público e da moral administrativa. É uma manifestação direta da soberania popular. Através dela, qualquer cidadão é parte legítima para obter a invalidação de atos ou contratos administrativos ilegais e lesivos do patrimônio federal, estadual e municipal, ou de suas autarquias, entidades paraestatais e pessoas jurídicas subvencionadas com dinheiros p

    Smart home environments have a significant potential to provide for long-term monitoring of users with special needs in order to promote the possibility to age at home. Such environments are typically equipped with a number of heterogeneous sensors that monitor both health and environmental parameters. This paper presents a framework called E-care@home, consisting of an IoT infrastructure, which provides information with an unambiguous, shared meaning across IoT devices, end-users, relatives, health and care professionals and organizations. We focus on integrating measurements gathered from heterogeneous sources by using ontologies in order to enable semantic interpretation of events and context awareness. Activities are deduced using an incremental answer set solver for stream reasoning. The paper demonstrates the proposed framework using an instantiation of a smart environment that is able to perform context recognition based on the activities and the events occurring in the home.

    We review the current status from the scientific and technological point of view of solar energetic particles, solar and galactic cosmic ray measurements as well as high energy UV-, X- and gamma-ray imaging of the Sun. These particles and electromagnetic data are an important tool for space situational awareness (SSA) aspects like space weather storm predictions to avoid failures in space, air and ground based technological systems. Real time data acquisition, position and energy sensitive imaging are demanded by the international space weather forecast services. We present how newly developed, highly miniaturized radiation detectors can find application in space in view of future SSA related satellites as a novel space application due to their counting and imaging capabilities.

    The increase of technological complexity in surgery has created a need for novel man-machine interaction techniques. Specifically, context-aware systems which automatically adapt themselves to the current circumstances in the OR have great potential in this regard. To create such systems, models of surgical procedures are vital, as they allow analyzing the current situation and assessing the context. For this purpose, we have developed a Surgical Process Model based on Description Logics. It incorporates general medical background knowledge as well as intraoperatively observed situational knowledge. The representation consists of three parts: the Background Knowledge Model, the Preoperative Process Model and the Integrated Intraoperative Process Model. All models depend on each other and create a concise view on the surgery. As a proof of concept, we applied the system to a specific intervention, the laparoscopic distal pancreatectomy.

    Full Text Available Recent disasters have shown that having clearly defined preventive procedures and decisions is a critical component that minimizes evacuation hazards and ensures a rapid and successful evolution of evacuation plans. In this context, we present our Situation-Aware System for enhancing Evacuation Plans (SASEP system, which allows creating end-user business rules that technically support the specific events, conditions and actions related to evacuation plans. An experimental validation was carried out where 32 people faced a simulated emergency situation, 16 of them using SASEP and the other 16 using a legacy system based on static signs. From the results obtained, we compare both techniques and discuss in which situations SASEP offers a better evacuation route option, confirming that it is highly valuable when there is a threat in the evacuation route. In addition, a study about user satisfaction using both systems is presented showing in which cases the systems are assessed as satisfactory, relevant and not frustrating.

    In recent years, manufacturers of animal-based foods with health claims have encountered difficulties in the labeling of their products because of a lack of regulation on defining the functionality of animal-based foods. Therefore, this study was conducted to establish the basic requirements for the development of a definition for functional animal-based foods by investigating consumer and industry awareness. Survey data were collected from 114 industry representatives and 1,100 consumers. The questions of the survey included items on production status and future production plans, functionality labeling, promotion plans, establishment of definition, the role of the government, consumer perception, and selection of products. The results show that both industry representatives and consumers believe that legislation and the provision of scientific evidence should be improved for the development of a functional animal-based foods market. The results obtained from this study will contribute to consumer trust by supplying correct information and can be utilized in the industry as basic data for the development of functional animal-based food products.

    The past decade has seen an 'explosion' in electronically archived evidence available on the Internet. Access to, and awareness of, pre-appraised web based evidence such as is available at the Cochrane Library, and more recently the Cancer Library, is now easily accessible to both clinicians and patients. A postal survey was recently sent out to all Radiation Oncology registrars in Australia, New Zealand and Singapore. The aim of the survey was to ascertain previous training in literature searching and critical appraisal, the extent of Internet access and use of web based evidence and awareness of databases including the Cochrane Library. Sixty six (66) out of ninety (90) registrars responded (73% response rate). Fifty five percent of respondents had previously undertaken some form of training related to literature searching or critical appraisal. The majority (68%) felt confident in performing a literature search, although 80% of respondents indicated interest in obtaining further training. The majority (68%) reported accessing web-based evidence for literature searching in the previous week, and 92% in the previous month. Nearly all respondents (89%) accessed web-based evidence at work. Most (94%) were aware of the Cochrane Library with 48% of respondents having used this database. Sixty-eight percent were aware of the Cancer Library. In 2000 a similar survey revealed only 68% of registrars aware and 30% having used the Cochrane Library. These findings reveal almost universal access to the Internet and use of web-based evidence amongst Radiation Oncology registrars. There has been a marked increase in awareness and use of the Cochrane Library with the majority also aware of the recently introduced Cancer Library

    Full Text Available AimThe aim of this study was to assess awareness of performance and performance accuracy for a task that requires executive functions (EF, among healthy adolescents and to compare their performance to their parent’s ratings.MethodParticipants: 109 healthy adolescents (mean age 15.2 ± 1.86 years completed the Weekly Calendar Planning Activity (WCPA. The discrepancy between self-estimated and actual performance was used to measure the level of awareness. The participants were divided into high and low accuracy groups according to the WCPA accuracy median score. The participants were also divided into high and low awareness groups. A comparison was conducted between groups using WCPA performance and parent ratings on the Behavior Rating Inventory of Executive Function (BRIEF.ResultsHigher awareness was associated with better EF performance. Participants with high accuracy scores were more likely to show high awareness of performance as compared to participants with low accuracy scores. The high accuracy group had better parental ratings of EF, higher efficiency, followed more rules, and were more aware of their WCPA performance.ConclusionOur results highlight the important contribution that self-awareness of performance may have on the individual’s function. Assessing the level of awareness and providing metacognitive training techniques for those adolescents who are less aware, could support their performance.

    2012-02-01

    Full Text Available While for years traditional wireless sensor nodes have been based on ultra-low power microcontrollers with sufficient but limited computing power, the complexity and number of tasks of today’s applications are constantly increasing. Increasing the node duty cycle is not feasible in all cases, so in many cases more computing power is required. This extra computing power may be achieved by either more powerful microcontrollers, though more power consumption or, in general, any solution capable of accelerating task execution. At this point, the use of hardware based, and in particular FPGA solutions, might appear as a candidate technology, since though power use is higher compared with lower power devices, execution time is reduced, so energy could be reduced overall. In order to demonstrate this, an innovative WSN node architecture is proposed. This architecture is based on a high performance high capacity state-of-the-art FPGA, which combines the advantages of the intrinsic acceleration provided by the parallelism of hardware devices, the use of partial reconfiguration capabilities, as well as a careful power-aware management system, to show that energy savings for certain higher-end applications can be achieved. Finally, comprehensive tests have been done to validate the platform in terms of performance and power consumption, to proof that better energy efficiency compared to processor based solutions can be achieved, for instance, when encryption is imposed by the application requirements.

    The purpose of this thesis is to provide a theoretical framework and its evaluation methodology of team dynamic task performance of operating team at nuclear power plant under the dynamic and tactical environment such as radiological accident. This thesis suggested a team dynamic task performance evaluation model so called team crystallization model stemmed from Endsely's situation awareness model being comprised of four elements: state, information, organization, and orientation and its quantification methods using system dynamics approach and a communication process model based on a receding horizon control approach. The team crystallization model is a holistic approach for evaluating the team dynamic task performance in conjunction with team situation awareness considering physical system dynamics and team behavioral dynamics for a tactical and dynamic task at nuclear power plant. This model provides a systematic measure to evaluate time-dependent team effectiveness or performance affected by multi-agents such as plant states, communication quality in terms of transferring situation-specific information and strategies for achieving the team task goal at given time, and organizational factors. To demonstrate the applicability of the proposed model and its quantification method, the case study was carried out using the data obtained from a full-scope power plant simulator for 1,000MWe pressurized water reactors with four on-the-job operating groups and one expert group who knows accident sequences. Simulated results team dynamic task performance with reference key plant parameters behavior and team-specific organizational center of gravity and cue-and-response matrix illustrated good symmetry with observed value. The team crystallization model will be useful and effective tool for evaluating team effectiveness in terms of recruiting new operating team for new plant as cost-benefit manner. Also, this model can be utilized as a systematic analysis tool for

    2012-12-01

    Along with the growing of the aging population and the necessity of efficient wellness systems, there is a mounting demand for new technological solutions able to support remote and proactive healthcare. An answer to this need could be provided by the joint use of the emerging Radio Frequency Identification (RFID) technologies and advanced software choices. This paper presents a proposal for a context-aware infrastructure for ubiquitous and pervasive monitoring of heterogeneous healthcare-related scenarios, fed by RFID-based wireless sensors nodes. The software framework is based on a general purpose architecture exploiting three key implementation choices: ontology representation, multi-agent paradigm and rule-based logic. From the hardware point of view, the sensing and gathering of context-data is demanded to a new Enhanced RFID Sensor-Tag. This new device, de facto, makes possible the easy integration between RFID and generic sensors, guaranteeing flexibility and preserving the benefits in terms of simplicity of use and low cost of UHF RFID technology. The system is very efficient and versatile and its customization to new scenarios requires a very reduced effort, substantially limited to the update/extension of the ontology codification. Its effectiveness is demonstrated by reporting both customization effort and performance results obtained from validation in two different healthcare monitoring contexts.

    Space situational awareness (SSA) and defense space control capabilities are top priorities for groups that own or operate man-made spacecraft. Also, with the growing amount of space debris, there is an increase in demand for contextual understanding that necessitates the capability of collecting and processing a vast amount sensor data. Cloud computing, which features scalable and flexible storage and computing services, has been recognized as an ideal candidate that can meet the large data contextual challenges as needed by SSA. Cloud computing consists of physical service providers and middleware virtual machines together with infrastructure, platform, and software as service (IaaS, PaaS, SaaS) models. However, the typical Virtual Machine (VM) abstraction is on a per operating systems basis, which is at too low-level and limits the flexibility of a mission application architecture. In responding to this technical challenge, a novel adaptive process based cloud infrastructure for SSA applications is proposed in this paper. In addition, the details for the design rationale and a prototype is further examined. The SSA Cloud (SSAC) conceptual capability will potentially support space situation monitoring and tracking, object identification, and threat assessment. Lastly, the benefits of a more granular and flexible cloud computing resources allocation are illustrated for data processing and implementation considerations within a representative SSA system environment. We show that the container-based virtualization performs better than hypervisor-based virtualization technology in an SSA scenario.

  20. The sociology of popular music, interdisciplinarity and aesthetic autonomy.

    Science.gov (United States)

    Marshall, Lee

    2011-03-01

    This paper considers the impact of interdisciplinarity upon sociological research, focusing on one particular case: the academic study of popular music. 'Popular music studies' is an area of research characterized by interdisciplinarity and, in keeping with broader intellectual trends, this approach is assumed to offer significant advantages. As such, popular music studies is broadly typical of contemporary intellectual and governmental attitudes regarding the best way to research specific topics. Such interdisciplinarity, however, has potential costs and this paper highlights one of the most significant: an over-emphasis upon shared substantive interests and subsequent undervaluation of shared epistemological understandings. The end result is a form of 'ghettoization' within sociology itself, with residents of any particular ghetto displaying little awareness of developments in neighbouring ghettos. Reporting from one such ghetto, this paper considers some of the ways in which the sociology of popular music has been limited by its positioning within an interdisciplinary environment and suggests two strategies for developing a more fully-realized sociology of popular music. First, based on the assumption that a sociological understanding of popular music shares much in common with a sociological understanding of everything else, this paper calls for increased intradisciplinary research between sociologists of varying specialisms. The second strategy, however, involves a reconceptualization of the disciplinary limits of sociology, as it argues that a sociology of popular music needs to accept musical specificity as part of its remit. Such acceptance has thus far been limited not only by an interdisciplinary context but also by the long-standing sociological scepticism toward the analysis of aesthetic objects. As such, this paper offers an intervention into wider debates concerning the remit of sociological enquiry, and whether it is ever appropriate for sociological

  3. State-Transition-Aware Spilling Heuristic for MLC STT-RAM-Based Registers

    2017-01-01

    Full Text Available Multilevel Cell Spin-Transfer Torque Random Access Memory (MLC STT-RAM is a promising nonvolatile memory technology to build registers for its natural immunity to electromagnetic radiation in rad-hard space environment. Unlike traditional SRAM-based registers, MLC STT-RAM exhibits unbalanced write state transitions due to the fact that the magnetization directions of hard and soft domains cannot be flipped independently. This feature leads to nonuniform costs of write states in terms of latency and energy. However, current SRAM-targeting register allocations do not have a clear understanding of the impact of the different write state-transition costs. As a result, those approaches heuristically select variables to be spilled without considering the spilling priority imposed by MLC STT-RAM. Aiming to address this limitation, this paper proposes a state-transition-aware spilling cost minimization (SSCM policy, to save power when MLC STT-RAM is employed in register design. Specifically, the spilling cost model is first constructed according to the linear combination of different state-transition frequencies. Directed by the proposed cost model, the compiler picks up spilling candidates to achieve lower power and higher performance. Experimental results show that the proposed SSCM technique can save energy by 19.4% and improve the lifetime by 23.2% of MLC STT-RAM-based register design.

    Full Text Available Our research deals with the development of a new type of game-based learning environment: (MMORPG based on mixed reality, applied in the archaeological domain. In this paper, we propose a learning scenario that enhances players’ motivation thanks to individual, collaborative and social activities and that offers a continuous experience between the virtual environment and real places (archaeological sites, museum. After describing the challenge to a rich multidisciplinary approach involving both computer scientists and archaeologists, we present two types of game: multiplayer online role-playing games and mixed reality games. We build on the specificities of these games to make the design choices described in the paper. We also present three modular features we have developed to support independently three activities of the scenario. The proposed approach aims at raising awareness among people on the scientific approach in Archaeology, by providing them information in the virtual environment and encouraging them to go on real sites. We finally discuss the issues raised by this work, such as the tensions between the perceived individual, team and community utilities, as well as the choice of the entering point in the learning scenario (real or virtual for the players’ involvement in the game.

    To assess user satisfaction and acceptability toward a cellphone-based short message system (SMS) application for fertility awareness. Between July 1 and September 30, 2013, the present observational study recruited women of reproductive age were presenting for family-planning services in Lucknow, India, who were not pregnant, who agreed to use the application, and who understood basic English. The application collected information on an individual's menstrual cycle and, using the calendar days approach, predicted fertility. Based on an algorithm, the application sent a daily SMS text indicating the participant's fertility status. Participants completed an acceptability survey at the end of the 60-day pilot period. There were 21 participants enrolled. All reported that the application was highly acceptable, and found it to be private, secure, and convenient. All participants were interested in receiving future SMS reminders for tracking fertility. Most participants (20 [95%]) reported being likely or very likely to recommend the family planning application to friends. The application, with the aims of helping participants to identify their most fertile days once a month during ovulation and make informed decisions regarding fertility and contraception, was highly acceptable and might be useful in low-resource settings worldwide. Larger studies are needed for software optimization and determination of long-term effectiveness. This article is protected by copyright. All rights reserved. This article is protected by copyright.

    Energy efficiency and balancing is one of the primary challenges for wireless sensor networks (WSNs) since the tiny sensor nodes cannot be easily recharged once they are deployed. Up to now, many energy efficient routing algorithms or protocols have been proposed with techniques like clustering, data aggregation and location tracking etc. However, many of them aim to minimize parameters like total energy consumption, latency etc., which cause hotspot nodes and partitioned network due to the overuse of certain nodes. In this paper, a Distance-based Energy Aware Routing (DEAR) algorithm is proposed to ensure energy efficiency and energy balancing based on theoretical analysis of different energy and traffic models. During the routing process, we consider individual distance as the primary parameter in order to adjust and equalize the energy consumption among involved sensors. The residual energy is also considered as a secondary factor. In this way, all the intermediate nodes will consume their energy at similar rate, which maximizes network lifetime. Simulation results show that the DEAR algorithm can reduce and balance the energy consumption for all sensor nodes so network lifetime is greatly prolonged compared to other routing algorithms.

    Full Text Available LLNs are gradually attracting people’s attention for the feature of low energy consumption. RPL is specifically designed for LLNs to construct a high energy efficiency network topology. In the noisy environment, the packet loss rate of RPL-based WSN increases during data transmission. The DODAG constructed by RPL-based WSN increases in depth when communication is affected by noise. In this situation the data transmission in the network will consume more energy. In event detection WSNs, the appropriate network topology enables root to use less sensor data to fuse enough information to determine whether or not an event has occurred. In this paper, we will improve RPL in two ways to optimize topology and reduce energy consumption. (1 The neighbor list and the information of DIO sender’s parent of a node are used to construct a better DODAG in the noisy environment. (2 SPRT and the quality of information of the data are used in the event detecting process for saving energy consumption. Simulation results show that, compared with the original RPL, QoI-aware RPL can reduce the energy consumption by collecting the same quality of information with less data transmission.

    For a number of years now the operational limitations of the standard radiation belt models have been widely discussed. Doses from specific parts of the spectrum can be over- or under-estimated. The averaging procedures used do not give statistical distributions or worst case fluences. And, critically, the models are not time-dependent or real time. Here we present a new approach to radiation belt specification that provides fluxes, fluences, or dose rates for any arbitrary orbit and for any arbitrary mission duration up to and including real time. DREAM ( the Dynamic Radiation Environment Assimilation Model) uses data assimilation techniques to combine measurements from geosynchronous and GPS satellites along with a physics-based model to derive optimal state specification of the full radiation belts. The physical equations are solved by evolving phase space density at fixed adiabatic invariants. Once the underlying physical equations are solved and optimized with the current measured state (based on the observations), the phase space density representation is inverted back to physical space and physical fluxes. We show initial results for 6-months in 2002 and compare the orbital dose rates predicted by DREAM with those measured by HEO satellites. We also discuss how this model could be implemented with real time data to provide space situational awareness and short term radiation belt forecasts.

    Work-related musculoskeletal disorders (WMSDs) related to computer work have become a serious public health concern. Literature revealed a positive association between computer use and WMSDs. The purpose of this evidence-based pilot project was to provide a series of evidence-based educational sessions on ergonomics to office computer workers to enhance the awareness of risk factors of WMSDs. Seventeen office computer workers who work for the National Board of Certification in Occupational Therapy volunteered for this project. Each participant completed a baseline and post-intervention ergonomics questionnaire and attended six educational sessions. The Rapid Office Strain Assessment and an ergonomics questionnaire were used for data collection. The post-intervention data revealed that 89% of participants were able to identify a greater number of risk factors and answer more questions correctly in knowledge tests of the ergonomics questionnaire. Pre- and post-intervention comparisons showed changes in work posture and behaviors (taking rest breaks, participating in exercise, adjusting workstation) of participants. The findings have implications for injury prevention in office settings and suggest that ergonomics education may yield positive knowledge and behavioral changes among computer workers.

    Cloud computing gets increasing attention for its capacity to leverage developers from infrastructure management tasks. However, recent works reveal that side channel attacks can lead to privacy leakage in the cloud. Enhancing isolation between users is an effective solution to eliminate the attack. In this paper, to eliminate side channel attacks, we investigate the isolation enhancement scheme from the aspect of virtual machine (VM) management. The security-awareness VMs management scheme (SVMS), a VMs isolation enhancement scheme to defend against side channel attacks, is proposed. First, we use the aggressive conflict of interest relation (ACIR) and aggressive in ally with relation (AIAR) to describe user constraint relations. Second, based on the Chinese wall policy, we put forward four isolation rules. Third, the VMs placement and migration algorithms are designed to enforce VMs isolation between the conflict users. Finally, based on the normal distribution, we conduct a series of experiments to evaluate SVMS. The experimental results show that SVMS is efficient in guaranteeing isolation between VMs owned by conflict users, while the resource utilization rate decreases but not by much.

    Full Text Available Currently, the field of smart-* (home, city, health, tourism, etc. is naturally heterogeneous and multimedia oriented. In such a domain, there is an increasing usage of heterogeneous mobile devices, as well as captors transmitting data (IoT. They are highly connected and can be used for many different services, such as to monitor, to analyze and to display information to users. In this context, data management and adaptation in real time are becoming a challenging task. More precisely, at one time, it is necessary to handle in a dynamic, intelligent and transparent framework various data provided by multiple devices with several modalities. This paper presents a Kali-Smart platform, which is an autonomic semantic-based context-aware platform. It is based on semantic web technologies and a middleware providing autonomy and reasoning facilities. Moreover, Kali-Smart is generic and, as a consequence, offers to users a flexible infrastructure where they can easily control various interaction modalities of their own situations. An experimental study has been made to evaluate the performance and feasibility of the proposed platform.

    Human action recognition in 3D skeleton sequences has attracted a lot of research attention. Recently, Long Short-Term Memory (LSTM) networks have shown promising performance in this task due to their strengths in modeling the dependencies and dynamics in sequential data. As not all skeletal joints are informative for action recognition, and the irrelevant joints often bring noise which can degrade the performance, we need to pay more attention to the informative ones. However, the original LSTM network does not have explicit attention ability. In this paper, we propose a new class of LSTM network, Global Context-Aware Attention LSTM (GCA-LSTM), for skeleton based action recognition. This network is capable of selectively focusing on the informative joints in each frame of each skeleton sequence by using a global context memory cell. To further improve the attention capability of our network, we also introduce a recurrent attention mechanism, with which the attention performance of the network can be enhanced progressively. Moreover, we propose a stepwise training scheme in order to train our network effectively. Our approach achieves state-of-the-art performance on five challenging benchmark datasets for skeleton based action recognition.

    Full Text Available Today’s context-aware systems tend to be reactive or ‘pull’ based - the user requests or queries for some information and the system responds with the requested information. However, none of the systems anticipate the user’s intent and behavior, or take into account his current events and activities to pro-actively ‘push’ relevant information to the user. On the other hand, Proactive context-aware systems can predict and anticipate user intent and behavior, and act proactively on the users’ behalf without explicit requests from them. Two fundamental capabilities of such systems are: prediction and autonomy. In this paper, we address the second capability required by a context-aware system to act proactively i.e. acting autonomously without an explicit user request. To address it, we present a new paradigm for enabling proactivity in context-aware middleware systems by means of a Planning Framework based on HTN planning. We present the design of a Planning Framework within the infrastructure of our intelligent context-aware middleware called Rover II. We also implement this framework and evaluate its utility with several use cases. We also highlight the benefits of using such a framework in dynamic ubiquitous systems.

    Full Text Available Introduction: Diabetic Retinopathy (DR has emerged as an important cause of ocular morbidity and blindness in past 20 years. About one fifth of known diabetics are projected to have DR in their lifetime. Thus awareness about DR is an important determinant in reducing the burden of blindness due to DR. Aim: To identify the factors that accounts for poor awareness about DR among patients with Diabetes Mellitus (DM. Materials and Methods: Three hundred thirty cases of DM who were undergoing screening for the first time were subjected to questionnaire to assess their awareness about DR. On the basis of awareness about visual blurring caused by diabetes the cases were divided into two groups, Group I included aware cases and Group II unaware cases. Various factors were then compared between these two groups like demographic profile, literacy level, Socioeconomic Class (SEC, family history, type and duration of DM. All cases were under treatment for DM and majority was on oral hypoglycaemic agents. Results: The study included 330 cases undergoing retinal screening for the first time. The mean age of the study group was 52.8±11.3 years with 54.5% male and 45.5% female cases. Overall, 226 cases (68.5% were aware that DM could lead to visual impairment (Group I and 104 (31.5% cases were unaware of the condition (Group II. Awareness was more in male patients (54.5%, with positive family history (23%, with higher educational qualification (70% and those belonging to a high SEC (55.8%. The rate of referral by the first contact physician for routine DR screening was 21.2%. The source of information for most of the cases was print media. Conclusion: Literacy and SEC are important factors for awareness of DR. Practice pattern among primary care physician also affects the awareness of DR.

    Due to the rapid growth of wireless medical devices in near future, wireless healthcare services may face some inescapable issue such as medical spectrum scarcity, electromagnetic interference (EMI), bandwidth constraint, security and finally medical data communication model. To mitigate these issues, cognitive radio (CR) or opportunistic radio network enabled wireless technology is suitable for the upcoming wireless healthcare system. The up-to-date research on CR based healthcare has exposed some developments on EMI and spectrum problems. However, the investigation recommendation on system design and network model for CR enabled hospital is rare. Thus, this research designs a hierarchy based hybrid network architecture and network maintenance protocols for previously proposed CR hospital system, known as CogMed. In the previous study, the detail architecture of CogMed and its maintenance protocols were not present. The proposed architecture includes clustering concepts for cognitive base stations and non-medical devices. Two cluster head (CH selector equations are formulated based on priority of location, device, mobility rate of devices and number of accessible channels. In order to maintain the integrity of the proposed network model, node joining and node leaving protocols are also proposed. Finally, the simulation results show that the proposed network maintenance time is very low for emergency medical devices (average maintenance period 9.5 ms) and the re-clustering effects for different mobility enabled non-medical devices are also balanced.

    Full Text Available Security is a critical issue for sensor networks used in hostile environments. When wireless sensor nodes in a wireless sensor network are distributed in an insecure hostile environment, the sensor nodes must be protected: a secret key must be used to protect the nodes transmitting messages. If the nodes are not protected and become compromised, many types of attacks against the network may result. Such is the case with existing schemes, which are vulnerable to attacks because they mostly provide a hop-by-hop paradigm, which is insufficient to defend against known attacks. We propose a location-aware dynamic session-key management protocol for grid-based wireless sensor networks. The proposed protocol improves the security of a secret key. The proposed scheme also includes a key that is dynamically updated. This dynamic update can lower the probability of the key being guessed correctly. Thus currently known attacks can be defended. By utilizing the local information, the proposed scheme can also limit the flooding region in order to reduce the energy that is consumed in discovering routing paths.

    2016-08-01

    A multitude of assistive devices is available for deaf people (i.e. deaf, deafened, and hard of hearing). Besides hearing and communication aids, devices to access environmental sounds are available commercially. But the devices have two major drawbacks: 1. they are targeted at indoor environments (e.g. home or work), and 2. only specific events are supported (e.g. the doorbell or telephone). Recent research shows that important sounds can occur in all contexts and that the interests in sounds are diverse. These drawbacks can be tackled by using modern information and communication technology that enables the development of new and improved assistive devices. The smartwatch, a new computing platform in the form of a wristwatch, offers new potential for assistive technology. Its design promises a perfect integration into various different social contexts and thus blends perfectly into the user's life. Based on a smartwatch and algorithms from pattern recognition, a prototype for awareness of environmental sounds is presented here. It observes the acoustic environment of the user and detects environmental sounds. A vibration is triggered when a sound is detected and the type of sound is shown on the display. The design of the prototype was discussed with deaf people in semi-structured interviews, leading to a set of implications for the design of such a device.

    2015-01-01

    Full Text Available Mobile ad hoc network (MANET is a collection of autonomous mobile nodes forming an ad hoc network without fixed infrastructure. Dynamic topology property of MANET may degrade the performance of the network. However, multipath selection is a great challenging task to improve the network lifetime. We proposed an energy-aware multipath routing scheme based on particle swarm optimization (EMPSO that uses continuous time recurrent neural network (CTRNN to solve optimization problems. CTRNN finds the optimal loop-free paths to solve link disjoint paths in a MANET. The CTRNN is used as an optimum path selection technique that produces a set of optimal paths between source and destination. In CTRNN, particle swarm optimization (PSO method is primly used for training the RNN. The proposed scheme uses the reliability measures such as transmission cost, energy factor, and the optimal traffic ratio between source and destination to increase routing performance. In this scheme, optimal loop-free paths can be found using PSO to seek better link quality nodes in route discovery phase. PSO optimizes a problem by iteratively trying to get a better solution with regard to a measure of quality. The proposed scheme discovers multiple loop-free paths by using PSO technique.

    Location based services (LBS) let people retrieve and share information related to their current position. Examples are Google Latitude or Panoramio. Since LBS share user-related content, location information etc., they put user privacy at risk. Literature has proposed various privacy mechanisms for LBS. However, it is unclear which mechanisms humans really find useful, and how they make use of them. We present a user study that addresses these issues. To obtain realistic results, we have implemented a geotagging application on the web and on GPS cellphones, and our study participants use this application in their daily lives. We test five privacy mechanisms that differ in the awareness, mental effort and degree of informedness required from the users. Among other findings, we have observed that in situations where a single simple mechanism does not meet all privacy needs, people want to use simple and sophisticated mechanisms in combination. Further, individuals are concerned about the privacy of others, even when they do not value privacy for themselves.

    Sun, Jianglin; Liao, Xiaofeng; Chen, Xin; Guo, Shangwei

    The increasing need for image communication and storage has created a great necessity for securely transforming and storing images over a network. Whereas traditional image encryption algorithms usually consider the security of the whole plain image, region of interest (ROI) encryption schemes, which are of great importance in practical applications, protect the privacy regions of plain images. Existing ROI encryption schemes usually adopt approximate techniques to detect the privacy region and measure the quality of encrypted images; however, their performance is usually inconsistent with a human visual system (HVS) and is sensitive to statistical attacks. In this paper, we propose a novel privacy-aware ROI image encryption (PRIE) scheme based on logistical mapping and data hiding. The proposed scheme utilizes salient object detection to automatically, adaptively and accurately detect the privacy region of a given plain image. After private pixels have been encrypted using chaotic cryptography, the significant bits are embedded into the nonprivacy region of the plain image using data hiding. Extensive experiments are conducted to illustrate the consistency between our automatic ROI detection and HVS. Our experimental results also demonstrate that the proposed scheme exhibits satisfactory security performance.

    Traditional medical school curricula have not addressed fertility awareness-based methods (FABMs) of family planning. The objective of this study was to assess (1) 3-year medical students' knowledge of FABMs of family planning, (2) their confidence in utilizing that knowledge in patient care, and (3) to implement focused education on FABMs to improve knowledge and confidence. Third-year medical students at one institution in the United States were given a 10-question assessment at the beginning of their OB-GYN rotation. Two lectures about FABMs and their clinical applications were given during the rotation. Students were given the same questions at the end of the rotation. Each questionnaire consisted of eight questions to assess a student's knowledge of FABMs and two questions to assess the student's confidence in sharing and utilizing that information in a clinical setting. McNemar's test was used to analyze the data. Two hundred seventy-seven students completed a pretest questionnaire and 196 students completed the posttest questionnaire. Medical knowledge improved from an initial test score of 38.99% to final test score of 53.57% ( p  family planning. This study shows that brief, focused education can increase medical students' knowledge of and confidence with FABMs of family planning.

  6. A Credit-Based Congestion-Aware Incentive Scheme for DTNs

    2016-12-01

    Full Text Available In Delay-Tolerant Networks (DTNs, nodes may be selfish and reluctant to expend their precious resources on forwarding messages for others. Therefore, an incentive scheme is necessary to motivate selfish nodes to cooperatively forward messages. However, the current incentive schemes mainly focus on encouraging nodes to participate in message forwarding, without considering the node congestion problem. When many messages are forwarded to the nodes with high connection degree, these nodes will become congested and deliberately discard messages, which will seriously degrade the routing performance and reduce the benefits of other nodes. To address this problem, we propose a credit-based congestion-aware incentive scheme (CBCAIS for DTNs. In CBCAIS, a check and punishment mechanism is proposed to prevent forwarding nodes from deliberately discarding message. In addition, a message acceptance selection mechanism is proposed to allow the nodes to decide whether to accept other messages, according to self congestion degree. The experimental results show that CBCAIS can effectively stimulate selfish nodes to cooperatively forward messages, and achieve a higher message delivery ratio with lower overhead ratio, compared with other schemes.

    Full Text Available How to provide safe and effective evacuation routes is an important safeguard to correctly guide evacuation and reduce the casualties during the fire situation rapidly evolving in complex indoor environment. The traditional static path finding method is difficult to adjust the path adaptively according to the changing fire situation, which lead to the evacuation decision-making blindness and hysteresis. This paper proposes a dynamic method which can dynamically optimize the indoor evacuation routes based on the real-time situation awareness. According to the real-time perception of fire situation parameters and the changing indoor environment information, the evacuation route is optimized dynamically. The integrated representation of multisource indoor fire monitoring sensor observations oriented fire emergency evacuation is presented at first, real-time fire threat situation information inside building is then extracted from the observation data of multi-source sensors, which is used to constrain the dynamical optimization of the topology of the evacuation route. Finally, the simulation experiments prove that this method can improve the accuracy and efficiency of indoor evacuation routing.

    Full Text Available The present inquiry inspected the impact of metacognitive awareness on the fluency of 114 Iranian TEFL learners’ task-based oral output. The participants in six intact classes were selected from a population of 120 English sophomores based on their scores on proficiency pre-test. The classes were randomly assigned as two tripartite groups of experimental and control participants each embracing three groups of pre-task planners (PTP, on-line task planners (OLP, and pre and on-line task planners (POLP. The fifteen-session metacognitive awareness program in the form of a topic-based listening and speaking course was based on Cotterall's (2000 principles of autonomous learning and three sets of metacognitive strategies, centering learning, arranging and planning learning and evaluating learning (Oxford, 1990. Employing a narrative task type, the researcher collected the data using a 2x3 factorial design with two levels of metacognitive awareness and three levels of planning. It was hypothesized that fluency would improve through metacognitive awareness under various planning conditions. Two-way Repeated Measures and One-way ANOVA analyses of the research data revealed significant fluency gains in all experimental participants compared to the control ones and in the control POLP planners. The findings have pedagogical implications for educators and teachers and highlight the need for strategic investment.

    Age-related eye disease is often considered part of natural aging. Lack of awareness of eye conditions can result in missed treatment. We investigated the rates of awareness of cataract and age-related macular degeneration, the most common age-related eye-diseases, and the associated factors among elderly Koreans. We identified 7,403 study subjects (≥40 years old) with cataract or age-related macular degeneration based on ophthalmic examination results during the 5th Korean National Health and Nutrition Examination Survey conducted between 2010 and 2012. We assessed whether patients were aware of their eye condition based on a previous diagnosis by a physician. The average awareness rate over the 3-year study period was 23.69% in subjects with cataract and 1.45% in subjects with age-related macular degeneration. Logistic regression analysis showed that patients with cataract were more likely to recognize their condition if they had myopia (odds ratio, 2.08), hyperopia (odds ratio, 1.33), family history of eye disease (odds ratio, 1.44), or a past eye examination (odds ratio, 4.07-29.10). The presence of diabetes mellitus was also a significant predictor of patient awareness of cataract (odds ratio, 1.88). Poor patient recognition of eye disease among the Korean elderly highlights the seriousness of this potential public health problem in our aging society. Pre-existing eye-related conditions and diabetes were significant predictors of awareness; therefore, patients in frequent contact with their doctors have a greater chance of detecting eye disease. © 2017 The Korean Ophthalmological Society

    With the emergence of Ultra-High Definition video, reference frame buffers (FBs) inside HEVC-like encoders and decoders have to sustain huge bandwidth. The power consumed by these external memory accesses accounts for a significant share of the codec's total consumption. This paper describes a solution to significantly decrease the FB's bandwidth, making HEVC encoder more suitable for use in power-aware applications. The proposed prototype consists in integrating an embedded lightweight, low-latency and visually lossless codec at the FB interface inside HEVC in order to store each reference frame as several compressed bitstreams. As opposed to previous works, our solution compresses large picture areas (ranging from a CTU to a frame stripe) independently in order to better exploit the spatial redundancy found in the reference frame. This work investigates two data reuse schemes namely Level-C and Level-D. Our approach is made possible thanks to simplified motion estimation mechanisms further reducing the FB's bandwidth and inducing very low quality degradation. In this work, we integrated JPEG XS, the upcoming standard for lightweight low-latency video compression, inside HEVC. In practice, the proposed implementation is based on HM 16.8 and on XSM 1.1.2 (JPEG XS Test Model). Through this paper, the architecture of our HEVC with JPEG XS-based frame buffer compression is described. Then its performance is compared to HM encoder. Compared to previous works, our prototype provides significant external memory bandwidth reduction. Depending on the reuse scheme, one can expect bandwidth and FB size reduction ranging from 50% to 83.3% without significant quality degradation.

    Stigmatizing attitudes toward mental illness and low mental health literacy have been identified as links to social adversity, and barriers to seeking and adhering to treatment among adolescents suffering from mental illness. Prior research has found that it is possible to improve these outcomes using school-based mental health awareness interventions. The purpose of this study was to review empirical literature pertaining to universal mental health awareness interventions aiming to improve mental health related outcomes among students enrolled in US K-12 schools, especially minorities vulnerable to health disparities. PsycINFO, Cochrane Library, PUBMED, and reference lists of relevant articles were searched for K-12 school-based mental health awareness interventions in the United States. Universal studies that measured knowledge, attitudes, and/or help-seeking pertinent to mental health were included. A total of 15 studies were selected to be part of the review. There were 7 pretest/post-test case series, 5 nonrandomized experimental trial, 1 Solomon 4-groups, and 2 randomized controlled trial (RCT) designs. Nine studies measuring knowledge, 8 studies measuring attitudes, and 4 studies measuring help-seeking, indicated statistically significant improvements. Although results of all studies indicated some level of improvement, more research on implementation of universal school-based mental health awareness programs is needed using RCT study designs, and long-term follow-up implementation. © 2016, American School Health Association.

    2013-04-01

    We carried out a cross-sectional study to determine the level of knowledge and awareness regarding children's food safety issues among the school-based street food vendors in Dhaka city. A total of 250 school-based street food vendors were interviewed employing a pre-tested structured questionnaire comprising foodborne illness and food hygiene-related questions. We used a scoring system based on the responses obtained from them, and categorized the overall level of knowledge and awareness into "adequate" and "inadequate." Multivariable logistic regression was used to explore the association between selected sociodemographic characteristics and the level of knowledge and awareness. The most common food item vended by school-based street food vendors was chotpoti/fuchka (37.2%). The median number of schoolchildren customers was 120 per vendor per day. All (100%) vendors were male with a mean age of 30.95±8.8 years, and their mean daily income was 131.16±62.54 Bangladeshi Taka (1.97±0.94 USD). Most (40.1%) of the respondents belonged to the age group 25-34 years, and the majority (43.6%) did not have any formal education. More than two-thirds (68%) vendors could not show adequate level of knowledge and awareness of children's food safety issues. The most common source of obtaining food safety information by vendors was electronic media (91.8%). Elderly (≥45 years) vendors were 17.73 times more likely to have adequate level of knowledge and awareness than the vendors belonging to age group 15-24 years (pawareness than those who did not have any formal education (pawareness of children's food safety issues.

    Network science plays a big role in the representation of real-world phenomena such as user-item bipartite networks presented in e-commerce or social media platforms. It provides researchers with tools and techniques to solve complex real-world problems. Identifying and predicting future popularity and importance of items in e-commerce or social media platform is a challenging task. Some items gain popularity repeatedly over time while some become popular and novel only once. This work aims to identify the key-factors: popularity and novelty. To do so, we consider two types of novelty predictions: items appearing in the popular ranking list for the first time; and items which were not in the popular list in the past time window, but might have been popular before the recent past time window. In order to identify the popular items, a careful consideration of macro-level analysis is needed. In this work we propose a model, which exploits item level information over a span of time to rank the importance of the item. We considered ageing or decay effect along with the recent link-gain of the items. We test our proposed model on four various real-world datasets using four information retrieval based metrics.

Despite an increasing prevalence of HTN in this country, information about the awareness, treatment, and control of HTN is limited. The objectives of this study were to describe the prevalence, awareness, treatment, and control of HTN, and factors associated with these endpoints, in residents of a mountainous province in Vietnam.Data from 2,368 adults (age≥25 years participating in a population-based survey conducted in 2011 in Thai Nguyen province were analyzed. All eligible participants completed a structured questionnaire and were examined by community health workers using a standardized protocol.The overall prevalence of HTN in this population was 23%. Older age, male sex, and being overweight were associated with a higher odds of having HTN, while higher educational level was associated with a lower odds of having HTN. Among those with HTN, only 34% were aware of their condition, 43% of those who were aware they had HTN received treatment and, of these, 39% had their HTN controlled.Nearly one in four adults in Thai Nguyen is hypertensive, but far fewer are aware of this condition and even fewer have their blood pressure adequately controlled. Public health strategies increasing awareness of HTN in the community, as well as improvements in the treatment and control of HTN, remain needed to reduce the prevalence of HTN and related morbidity and mortality.

    Allergic enterocolitis, also known as food protein-induced enterocolitis syndrome (FPIES), is an increasingly reported and potentially severe non-IgE mediated food allergy of the first years of life, which is often misdiagnosed due to its non-specific presenting symptoms and lack of diagnostic guidelines. We sought to determine the knowledge of clinical, diagnostic and therapeutic features of FPIES among Italian primary-care paediatricians. A 16-question anonymous web-based survey was sent via email to randomly selected primary care paediatricians working in the north of Italy. There were 194 completed surveys (48.5% response rate). Among respondents, 12.4% declared full understanding of FPIES, 49% limited knowledge, 31.4% had simply heard about FPIES and 7.2% had never heard about it. When presented with clinical anecdotes, 54.1% recognised acute FPIES and 12.9% recognised all chronic FPIES, whereas 10.3% misdiagnosed FPIES as allergic proctocolitis or infantile colic. To diagnose FPIES 55.7% declared to need negative skin prick test or specific-IgE to the trigger food, whereas 56.7% considered necessary a confirmatory oral challenge. Epinephrine was considered the mainstay in treating acute FPIES by 25.8% of respondents. Only 59.8% referred out to an allergist for the long-term reintroduction of the culprit food. Overall, 20.1% reported to care children with FPIES in their practice, with cow's milk formula and fish being the most common triggers; the diagnosis was self-made by the participant in 38.5% of these cases and by an allergist in 48.7%. There is a need for promoting awareness of FPIES to minimise delay in diagnosis and unnecessary diagnostic and therapeutic interventions. Copyright © 2016 SEICAP. Published by Elsevier España, S.L.U.

  3. Cost-effective handoff scheme based on mobility-aware dual pointer forwarding in proxy mobile IPv6 networks.

    Son, Seungsik; Jeong, Jongpil

    2014-01-01

    In this paper, a mobility-aware Dual Pointer Forwarding scheme (mDPF) is applied in Proxy Mobile IPv6 (PMIPv6) networks. The movement of a Mobile Node (MN) is classified as intra-domain and inter-domain handoff. When the MN moves, this scheme can reduce the high signaling overhead for intra-handoff/inter-handoff, because the Local Mobility Anchor (LMA) and Mobile Access Gateway (MAG) are connected by pointer chains. In other words, a handoff is aware of low mobility between the previously attached MAG (pMAG) and newly attached MAG (nMAG), and another handoff between the previously attached LMA (pLMA) and newly attached LMA (nLMA) is aware of high mobility. Based on these mobility-aware binding updates, the overhead of the packet delivery can be reduced. Also, we analyse the binding update cost and packet delivery cost for route optimization, based on the mathematical analytic model. Analytical results show that our mDPF outperforms the PMIPv6 and the other pointer forwarding schemes, in terms of reducing the total cost of signaling.

    Among the most persistent popular misperceptions of Galileo is the image of an irreligious scientist who opposed the Catholic Church and was therefore convicted of heresy-was even excommunicated, according to some accounts, and denied Christian burial. In fact, Galileo considered himself a good Catholic. He accepted the Bible as the true word of God on matters pertaining to salvation, but insisted Scripture did not teach astronomy. Emboldened by his discovery of the Medicean Moons, he took a stand on Biblical exegesis that has since become the official Church position.

    2017-08-16

    A significant challenge faced by visually impaired people is 'wayfinding', which is the ability to find one's way to a destination in an unfamiliar environment. This study develops a novel wayfinding system for smartphones that can automatically recognize the situation and scene objects in real time. Through analyzing streaming images, the proposed system first classifies the current situation of a user in terms of their location. Next, based on the current situation, only the necessary context objects are found and interpreted using computer vision techniques. It estimates the motions of the user with two inertial sensors and records the trajectories of the user toward the destination, which are also used as a guide for the return route after reaching the destination. To efficiently convey the recognized results using an auditory interface, activity-based instructions are generated that guide the user in a series of movements along a route. To assess the effectiveness of the proposed system, experiments were conducted in several indoor environments: the sit in which the situation awareness accuracy was 90% and the object detection false alarm rate was 0.016. In addition, our field test results demonstrate that users can locate their paths with an accuracy of 97%.

    2013-09-01

    Crashes between cars and trains at rail level crossings are problematic worldwide. Despite this, key facets of driver behaviour at rail level crossings, such as situation awareness and decision making, remain ambiguous. This is largely down to the inability of existing methodologies to describe or evaluate the cognitive aspects of driver behaviour when negotiating rail level crossings. This paper showcases an on-road approach for examining driver situation awareness at rail level crossings. The study presented involved participants, classified either as novice or experienced drivers, providing concurrent verbal protocols as they drove a pre-determined urban route incorporating four rail level crossings. Driver situation awareness was modelled using a network analysis-based approach and the structure and content of the networks was assessed. The analysis revealed key differences between novice and experienced drivers situation awareness at rail level crossings. In closing, the benefits of the on-road approach are discussed and a series of wider driver behaviour applications are proposed. Copyright © 2012 Elsevier Ltd. All rights reserved.

    The aim of this study was to assess the awareness of periodontal disease, its influence on general health, and attitude toward periodontal disease management among medical faculty in Guntur district. In this cross-sectional study, 150 medical faculty members from different specialties in Guntur district were included in the study. A self-administered questionnaire was prepared based on knowledge, attitude, and practice surveys to assess the awareness of periodontal disease and its management. Majority of the study participants (82%) had a previous dental visit. Only 31.3% believed that plaque is the major cause for periodontal disease. 56.7% responded that the relation between periodontal disease and systemic diseases is bidirectional. Only 39.3% were aware that periodontal disease is a risk factor for preterm low-birth weight infants. 52.6% of the medical faculty thought that scaling causes loss of enamel. 54.7% were aware that light amplification by stimulated emission of radiation is used in the periodontal treatment. Medical professionals who visited specialist in their previous dental visit obtained mean periodontal score (5.35 ± 1.686) greater than those who had visited general dentist and the difference is statistically significant (0.024). This study clearly demonstrates that medical practitioners had fair knowledge about various aspects of periodontal disease. This was particularly evident among those who have had a previous visit to a dentist. It was also found that young professionals with limited experience in the profession had better knowledge.

  3. Quality-aware features-based noise level estimator for block matching and three-dimensional filtering algorithm

    Science.gov (United States)

    Xu, Shaoping; Hu, Lingyan; Yang, Xiaohui

    2016-01-01

    The performance of conventional denoising algorithms is usually controlled by one or several parameters whose optimal settings depend on the contents of the processed images and the characteristics of the noises. Among these parameters, noise level is a fundamental parameter that is always assumed to be known by most of the existing denoising algorithms (so-called nonblind denoising algorithms), which largely limits the applicability of these nonblind denoising algorithms in many applications. Moreover, these nonblind algorithms do not always achieve the best denoised images in visual quality even when fed with the actual noise level parameter. To address these shortcomings, in this paper we propose a new quality-aware features-based noise level estimator (NLE), which consists of quality-aware features extraction and optimal noise level parameter prediction. First, considering that image local contrast features convey important structural information that is closely related to image perceptual quality, we utilize the marginal statistics of two local contrast operators, i.e., the gradient magnitude and the Laplacian of Gaussian (LOG), to extract quality-aware features. The proposed quality-aware features have very low computational complexity, making them well suited for time-constrained applications. Then we propose a learning-based framework where the noise level parameter is estimated based on the quality-aware features. Based on the proposed NLE, we develop a blind block matching and three-dimensional filtering (BBM3D) denoising algorithm which is capable of effectively removing additive white Gaussian noise, even coupled with impulse noise. The noise level parameter of the BBM3D algorithm is automatically tuned according to the quality-aware features, guaranteeing the best performance. As such, the classical block matching and three-dimensional algorithm can be transformed into a blind one in an unsupervised manner. Experimental results demonstrate that the

    Full Text Available Physical activity (PA promotion has proven effectiveness in preventing childhood obesity. Increasing children's health knowledge is the most frequently used approach in PA intervention programs targeting childhood obesity prevention. However, little is known about the specific association between the change in a child's knowledge awareness and their PA practice.A one-year follow-up study was conducted among primary and junior high school students in Nanjing, China. At baseline students' knowledge of healthy behavior, and their PA levels, were assessed. Students who were unaware of the association between PA and obesity were followed for one academic year. After nine-months their knowledge and PA levels were re-measured using the same validated questionnaire. Mixed effects regression models were used to estimate the relationship between awareness of knowledge about the link between PA and obesity and PA changes.Of the 1899 students who were unaware of the association between PA and obesity at baseline, 1859 (follow-up rate = 97.9% were successfully followed-up. After nine months 1318 (70.9% participants had become aware of PA-obesity association. Compared to their counterparts who remained unaware, students who became aware of the PA-obesity association were more likely to increase both the frequency (odds ratio (OR = 1.34, 95%CI = 1.09, 1.64 and duration (OR = 1.34, 95%CI = 1.09, 1.65 of PA, after adjusting for potentially confounding variables.Becoming aware of the known link between PA and obesity led to positive behavior modification regarding PA in this cohort of Chinese students. This is of particular importance that knowledge disimination and health education may be a useful approach for population-based physical activity promotion aiming at childhood obesity prevention in China.

    Dyslipidemia is an important independent modifiable risk factor for cardiovascular disease. The aim of this study was to explore the current prevalence, awareness, treatment and control of dyslipidemia and its associated influence factors in northeast China. In this population-based cross-sectional study, we adopted a multi-stage, stratified sampling method to obtain a representative sample of 4052 permanent residents aged 40 years and over from different urban and rural regions in Dehui City of Jilin Province. All subjects completed a questionnaire and were examined for risk factors. Continuous data were presented as means ± standard deviations (SD) and compared using the Student's t-test. Categorical variables were presented as proportions and compared using the Rao-Scott-χ 2 test in different subgroups. The associated influence factors for the prevalence, awareness, treatment and control of dyslipidemia were evaluated through multivariate logistic regression. The prevalence of dyslipidemia was 62.1% overall, with 33.5, 43.9, 0.6, and 8.8% for high total cholesterol, triglyceride, low-density lipoprotein cholesterol, and low high-density lipoprotein cholesterol, respectively. Among those with dyslipidemia, the proportion of subjects who were aware, treated, and controlled was 14.4, 33.9, and 19.9%, respectively. Overweight or obesity (OR = 2.156; 95% CI: 1.863, 2.533), hypertension (OR = 1.643; 95% CI: 1.425, 1.893), or diabetes mellitus (OR = 2.173; 95% CI: 1.661, 2.844) increased the prevalence of dyslipidemia, also these participants were more likely to be aware of their condition, however, this did not increase the likelihood of treatment and control. Living in urban areas and higher education level also increased the awareness of dyslipidemia. Personal history of coronary heart disease was the strongest influence factors associated with better awareness, treatment and control of dyslipidemia. Overweight or obesity (OR = 0.404; 95% CI

    The Internet of Things (IoT) has made it possible for devices around the world to acquire information and store it, in order to be able to use it at a later stage. However, this potential opportunity is often not exploited because of the excessively big interval between the data collection and the capability to process and analyse it. In this paper, we review the current IoT technologies, approaches and models in order to discover what challenges need to be met to make more sense of data. The main goal of this paper is to review the surveys related to IoT in order to provide well integrated and context aware intelligent services for IoT. Moreover, we present a state-of-the-art of IoT from the context aware perspective that allows the integration of IoT and social networks in the emerging Social Internet of Things (SIoT) term.

  10. Brian Bocking: A Popular Dictionary of Shinto

    1996-01-01

    This book is more than a popular dictionary of Shinto. The title arises, one may suppose, because the publisher would like it to reach a wide range of general and educational readers. There are indeed others in an untitled series by the same publisher dealing with Buddhism, Hinduism, Islam and Sikhism. As a specialist in Japanese religions, on the other hand, Brian Bocking (Bath College of Higher Education, Bath UK) is aware of the need for an academic dictionary of Shinto. Thus the book is a...

    Full Text Available Tele-rehabilitation is one of the main domains where Information and Communication Technologies (ICT have been proven useful to move healthcare from care centers to patients’ home. Moreover, patients, especially those carrying out a physical therapy, cannot use a traditional Window, Icon, Menu, Pointer (WIMP system, but they need to interact in a natural way, that is, there is a need to move from WIMP systems to Post-WIMP ones. Moreover, tele-rehabilitation systems should be developed following the context-aware approach, so that they are able to adapt to the patients’ context to provide them with usable and effective therapies. In this work a model-based approach is presented to assist stakeholders in the development of context-aware Post-WIMP tele-rehabilitation systems. It entails three different models: (i a task model for designing the rehabilitation tasks; (ii a context model to facilitate the adaptation of these tasks to the context; and (iii a bio-inspired presentation model to specify thoroughly how such tasks should be performed by the patients. Our proposal overcomes one of the limitations of the model-based approach for the development of context-aware systems supporting the specification of non-functional requirements. Finally, a case study is used to illustrate how this proposal can be put into practice to design a real world rehabilitation task.

    HIV diagnosis and linkage to care are the main barriers in Africa to achieving the UNAIDS 90-90-90 targets. We assessed HIV-positive status awareness and linkage to care among survey participants in Chiradzulu District, Malawi. Nested cohort study within a population-based survey of persons aged 15-59 years between February and May 2013. Participants were interviewed and tested for HIV (and CD4 if found HIV-positive) in their homes. Multivariable regression was used to determine factors associated with HIV-positive status awareness prior to the survey and subsequent linkage to care. Of 8277 individuals eligible for the survey, 7270 (87.8%) participated and were tested for HIV. The overall HIV prevalence was 17.0%. Among HIV-positive participants, 77.0% knew their status and 72.8% were in care. Women (adjusted odds ratio [aOR] 6.5, 95% CI 3.2-13.1) and older participants (40-59 vs. 15-29 years, aOR 10.1, 95% CI 4.0-25.9) were more likely to be aware of their positive status. Of those newly diagnosed, 47.5% were linked to care within 3 months. Linkage to care was higher among older participants (40-59 vs. 15-29, adjusted hazard ratio [aHR] 3.39, 95% CI 1.83-6.26), women (aHR 1.73, 95% CI 1.12-2.67) and those eligible for ART (aHR 1.61, 95% CI 1.03-2.52). In settings with high levels of HIV awareness, home-based testing remains an efficient strategy to diagnose and link to care. Men were less likely to be diagnosed, and when diagnosed to link to care, underscoring the need for a gender focus in order to achieve the 90-90-90 targets. © 2016 John Wiley & Sons Ltd.

    To understand current awareness of, and views on, treatment of alcohol dependence in Japan. (a) Nationwide internet-based survey of 520 individuals, consisting of 52 diagnosed alcohol-dependent (AD) persons, 154 potentially alcohol-dependent (ADP) persons, 104 family members and 106 friends/colleagues of AD persons, and 104 general individuals, derived from a consumer panel where the response rate was 64.3%. We enquired into awareness about the treatment of alcohol dependence and patient pathways through the healthcare network. (b) Nationwide internet-based survey of physicians (response rate 10.1% (2395/23,695) to ask 200 physicians about their management of alcohol use disorders). We deduced that 10% of alcohol-dependent Japanese persons had ever been diagnosed with alcohol dependence, with only 3% ever treated. Regarding putative treatment goals, 20-25% of the AD and ADP persons would prefer to attempt to abstain, while 60-75% preferred 'reduced drinking.' A half of the responding physicians considered abstinence as the primary treatment goal in alcohol dependence, while 76% considered reduced drinking as an acceptable goal. AD and ADP persons in Japan have low 'disease awareness' defined as 'understanding of signs, symptoms and consequences of alcohol use disorders,' which is in line with the overseas situation. The Japanese drinking culture and stigma toward alcohol dependence may contribute to such low disease awareness and current challenging treatment environment. While abstinence remains the preferred treatment goal among physicians, reduced drinking seems to be an acceptable alternative treatment goal to many persons and physicians in Japan. © The Author 2014.

    In this study, we aimed to investigate the prevalence, awareness, treatment, and control of diabetes in Shanghai, China. A sample of 3600 residents aged from 18 to 80 years selected by a randomized stratified multiple-stage sampling method in Shanghai was investigated, with blood samples collected. Diabetes was defined as fasting plasma glucose (FPG) ≥ 7.0 mmol/L, or glycated haemoglobin (HbA1c) ≥ 6.5% (48 mmol/mol), or previous diagnosis by a physician. Adequate control of diabetes was taken as a level of HbA1c diabetes. Multivariable regression analysis was used to explore associated factors for diabetes and prediabetes. In the 3136 participants suitable for analysis, the prevalences of diabetes, prediabetes, and previously diagnosed diabetes were 15.91%, 37.37%, and 4.46%, respectively. Among those with diabetes, only 28.06% were aware of their condition, 25.85% were currently undergoing medication treatment, and 12.42% achieved glycaemic control. Logistic regression showed that old age, preobesity, obesity, elevated triglyceride (TG), elevated C-reactive protein (CRP), and lower education level were associated with an increased risk of diabetes; old age, obesity, elevated TG, and elevated low-density lipoprotein (LDL) were associated with an increased risk of prediabetes, while male sex and rural residence were associated with a decreased risk of prediabetes. In summary, the state of diabetes in China is alarming; the rates of awareness, treatment, and control were relatively low. More efforts should be made to promote the prevention and control of diabetes in china.

    Maternal behavior before and after conception affects maternal and child health. Limited awareness of adolescents in preconception health may be addressed through school education. The aim of this intervention is to assess preconception health awareness among adolescents in Lebanese high schools and to test the effectiveness of a one-time educational session in improving preconception knowledge. The intervention consisted of a 30-minute educational session about good practices in preconception health, developed by the National Collaborative Perinatal Neonatal Network's (NCPNN) research team. A convenience sample of high school Lebanese students in grades 10 to 12, aged 14 to 26 years old, from 70 private and public schools in all six Lebanese provinces, participated in the intervention in 2011 and 2012. A multiple-choice questionnaire administered prior to and 2 months after the session was used to assess knowledge improvement among the students. A total of 7,290 students were enrolled. After the session, mean scores of correct answers increased from 4.36 to 6.42 out of 10, representing a 47.2% improvement (p improvement was observed for questions about Trisomy 21, folic acid intake and toxoplasmosis with percentages improvement of 96%, 172% and 83% respectively. Being female or in private school was a significant predictor of higher scores in both pre-test and post-test (p students. We recommend expanding the scope of this intervention into universities in Lebanon.

    Full Text Available Opportunities and needs are increasing to input Japanese sentences on mobile phones since performance of mobile phones is improving. Applications like E-mail, Web search, and so on are widely used on mobile phones now. We need to input Japanese sentences using only 12 keys on mobile phones. We have proposed a method to input Japanese sentences on mobile phones quickly and easily. We call this method number-Kanji translation method. The number string inputted by a user is translated into Kanji-Kana mixed sentence in our proposed method. Number string to Kana string is a one-to-many mapping. Therefore, it is difficult to translate a number string into the correct sentence intended by the user. The proposed context-aware mapping method is able to disambiguate a number string by artificial neural network (ANN. The system is able to translate number segments into the intended words because the system becomes aware of the correspondence of number segments with Japanese words through learning by ANN. The system does not need a dictionary. We also show the effectiveness of our proposed method for practical use by the result of the evaluation experiment in Twitter data.

    The principle that 'popularity is attractive' underlies preferential attachment, which is a common explanation for the emergence of scaling in growing networks. If new connections are made preferentially to more popular nodes, then the resulting distribution of the number of connections possessed by nodes follows power laws, as observed in many real networks. Preferential attachment has been directly validated for some real networks (including the Internet), and can be a consequence of different underlying processes based on node fitness, ranking, optimization, random walks or duplication. Here we show that popularity is just one dimension of attractiveness; another dimension is similarity. We develop a framework in which new connections optimize certain trade-offs between popularity and similarity, instead of simply preferring popular nodes. The framework has a geometric interpretation in which popularity preference emerges from local optimization. As opposed to preferential attachment, our optimization framework accurately describes the large-scale evolution of technological (the Internet), social (trust relationships between people) and biological (Escherichia coli metabolic) networks, predicting the probability of new links with high precision. The framework that we have developed can thus be used for predicting new links in evolving networks, and provides a different perspective on preferential attachment as an emergent phenomenon.

    Full Text Available Multicultural awareness is the foundation of communication and it involves the ability of standing back from ourselves and becoming aware of our cultural values, beliefs and perceptions. Multicultural awareness becomes central when we have to interact with people from other cultures. People see, interpret and evaluate things in a different ways. What is considered an appropriate behaviour in one culture is frequently inappropriate in another one. this research use descriptive- quantitative methodology to indentify level of students multicultural awareness specifically will be identified by gender and academic years. This research will identify multicultural awareness based on differences of gender, academic years. This research use random and purposive random sampling of 650 students from university. These studies identify of multicultural awareness 34, 11, 4% in high condition, 84, 1% medium and 4, 5% in low. Further, there is a significant difference in the level of multicultural awareness based on gender and academic year. These findings could not be generalized because of the limited sample and ethnicity; it should need a wider research so that can be generalized and recommended the efforts to development and improvement of multicultural awareness conditions for optimization the services.

  3. Nollywood, Popular Culture and Nigerian National Identity

    Full Text Available Film culture in Nigeria has become very popular among Nigerian and transnational audiences especially in Africa to the extent that there is hardly a day people do not look for new films produced by Nollywood. In the same light, there is hardly a street in the country where one cannot find at least a video shop that distributes these films. Young and old people especially those in the rural areas are often found hanging around these shops to catch a glimpse of any of the films advertised by retail outlets. This has therefore proven the popularity of Nollywood productions among the people, who see in these films issues of culture that engage their attention and also try to give them awareness about socio-cultural practices that are common in the society. A major problem of concern is that although these films expose and treat cultural issues that affect the society, their promotion of a true national identity is questionable. In this regard, this paper is an attempt to examine how the films produced by Nollywood have been able to promote national identity vis-à-vis showcasing the cultural values of the people that can be cherished in the Nigerian society and beyond. Arguments on this will be done through qualitative (interview method and supported by Kantian morality theory, which will help in concluding that as popular culture, Nigerian films have created among Nigerians and the world some cultural practices that tend to give the Nigerian people a negative identity.

RESULTS: there were statistical significance differences in the following findings: MALE - microphone during rehearsal, absence of diagnosed voice problems, lack of assistance on vocal hygiene, pain or discomfort after singing, but no allergies or respiratory problems; FEMALES - singing lessons and awareness of posture; AMATEUR - no dancing while singing, no imitating voices, lack of otolaryngological evaluation (ENT, no diagnosed vocal problems, lack of speech-language therapy, absence of guidelines on vocal anatomy/physiology and without alcohol consumption during the rehearsals; PROFESSIONAL- hoarseness, knowledge about articulation, alcohol consumption during performance, excess throat clearing, pain after singing. CONCLUSIONS: the comparison between genders showed male singers were using microphone in rehearsals, did not have respiratory or allergic problems, nor voice problems were diagnosed, but they had pain sensation or discomfort after singing and did not have vocal hygiene, and female singers had singing lessons and followed posture guidelines. The comparison between amateurs and professionals showed that amateur singers did not dance while singing, did not imitate voices, did not consume alcohol during rehearsals, and did not have diagnosed voice problems, but they did not have ENT evaluation, nor did they engage in speech-language therapy, and had no awareness of vocal anatomy/physiology; and the professional singers complained of hoarseness, excess throat clearing and pain after singing, and they consumed alcohol during singing, despite having knowledge about articulation.

    It is well-known that clustering partitions network into logical groups of nodes in order to achieve energy efficiency and to enhance dynamic channel access in cognitive radio through cooperative sensing. While the topic of energy efficiency has been well investigated in conventional wireless sensor networks, the latter has not been extensively explored. In this paper, we propose a reinforcement learning-based spectrum-aware clustering algorithm that allows a member node to learn the energy and cooperative sensing costs for neighboring clusters to achieve an optimal solution. Each member node selects an optimal cluster that satisfies pairwise constraints, minimizes network energy consumption and enhances channel sensing performance through an exploration technique. We first model the network energy consumption and then determine the optimal number of clusters for the network. The problem of selecting an optimal cluster is formulated as a Markov Decision Process (MDP) in the algorithm and the obtained simulation results show convergence, learning and adaptability of the algorithm to dynamic environment towards achieving an optimal solution. Performance comparisons of our algorithm with the Groupwise Spectrum Aware (GWSA)-based algorithm in terms of Sum of Square Error (SSE), complexity, network energy consumption and probability of detection indicate improved performance from the proposed approach. The results further reveal that an energy savings of 9% and a significant Primary User (PU) detection improvement can be achieved with the proposed approach.

    2017-06-01

    Full Text Available The management of riverine water always remains a big challenge, because the volatility of water flow creates hurdles to determine the exact time and quantity of water flowing in rivers and available for daily use. The volatile water caused by various water sources and irregular flow pattern generates different kinds of challenges for management. Distribution of flow of water in irrigation network affects the relevant community in either way. In the monsoon seasons, river belt community high risk of flood, while far living community suffering drought. Contemplating this situation, we have developed an ontology for context-aware information representation of riverine water management system abetting the visualization and proactive planning for the complex real-time situation. The purpose of this WaterOnto is to improve river water management and enable for efficient use of this precious natural resource. This would also be helpful to save the extra water being discharged in sea & non-irrigational areas, and magnitude and location of water leakage. We conceptualized stakeholder and relevant entities. We developed a taxonomy of irrigation system concepts in machine process able structure. Being woven these hierarchies together we developed a detailed conceptualization of river flow that helps us to manage the flow of water and enable to extract danger situation.

  11. A Wi-Fi based Electronic Road Sign for Enhancing the Awareness of Vehicle Driver

    2017-01-01

    Reducing the road accident rate is one of the city goal in the area of transportation. One of the effort to reach that goal is done by deploying various signs across the road. However, the role of those road signs can be diminished once the vehicle drivers intentionally or unintentionally disobey the rule indicated on those signs. In order to increase the awareness of the driver, we can employ the vehicular network concept in which a vehicle can communicate with another vehicles or with the infrastructure installed along the road. For realizing that idea, we propose the implementation of communication equipped road sign system which consists of two components: Road Side Unit (RSU) module deployed at road sign and On Board Unit (OBU) module deployed at each vehicle. In our proposed scheme, both of the devices communicate each other through the widely-used Wi-Fi protocol (IEEE 802.11n) operating in ad-hoc mode. While a OBU equipped vehicle is moving towards the communication range of RSU, it will make an association to a predefined wireless ad-hoc network. Once it is associated, the OBU can receive message broadcast by the RSU. Upon reception, OBU display alert message indicating that the vehicle is approaching a road sign. From performance testing we observe that the proposed system can give relatively good service the vehicle moving as fast as speed 90km/h with the distance as far as 90m.

  12. Traffic sign recognition based on a context-aware scale-invariant feature transform approach

    Science.gov (United States)

    Yuan, Xue; Hao, Xiaoli; Chen, Houjin; Wei, Xueye

    2013-10-01

    A new context-aware scale-invariant feature transform (CASIFT) approach is proposed, which is designed for the use in traffic sign recognition (TSR) systems. The following issues remain in previous works in which SIFT is used for matching or recognition: (1) SIFT is unable to provide color information; (2) SIFT only focuses on local features while ignoring the distribution of global shapes; (3) the template with the maximum number of matching points selected as the final result is instable, especially for images with simple patterns; and (4) SIFT is liable to result in errors when different images share the same local features. In order to resolve these problems, a new CASIFT approach is proposed. The contributions of the work are as follows: (1) color angular patterns are used to provide the color distinguishing information; (2) a CASIFT which effectively combines local and global information is proposed; and (3) a method for computing the similarity between two images is proposed, which focuses on the distribution of the matching points, rather than using the traditional SIFT approach of selecting the template with maximum number of matching points as the final result. The proposed approach is particularly effective in dealing with traffic signs which have rich colors and varied global shape distribution. Experiments are performed to validate the effectiveness of the proposed approach in TSR systems, and the experimental results are satisfying even for images containing traffic signs that have been rotated, damaged, altered in color, have undergone affine transformations, or images which were photographed under different weather or illumination conditions.

  13. Space activities and global popular music culture

    Science.gov (United States)

    Wessels, Allison Rae; Collins, Patrick

    During the "space age" era, space activities appear increasingly as a theme in Western popular music, as they do in popular culture generally. In combination with the electronics and tele-communications revolution, "pop/rock" music has grown explosively during the space age to become an effectively global culture. From this base a number of trends are emerging in the pattern of influences that space activities have on pop music. The paper looks at the use of themes and imagery in pop music; the role of space technology in the modern "globalization" of pop music; and current and future links between space activities and pop music culture, including how public space programmes are affected by its influence on popular attitudes.

    2012-01-01

    Access to basic healthcare in many parts of Papua New Guinea (PNG) remains a challenge partly because the majority of the population is thinly scattered across a geographically rugged country. The major health problems in PNG pertain to malaria, tuberculosis and diarrheal diseases while HIV has reached epidemic levels. The proliferation of the mobile phone technology in PNG has been unprecedented since the introduction of competition in the sector in July 2007. Users in rural areas now access the mobile phone signal making it their preferred form of modern communications medium. This paper introduces an SMS-based HIV/AIDS education, awareness and information dissemination model for a predominantly rural-based PNG society.

    2014-12-01

    Human movement differs from robot control because of its flexibility in unknown environments, robustness to perturbation, and tolerance of unknown parameters and unpredictable variability. We propose a new theory, risk-aware control, in which movement is governed by estimates of risk based on uncertainty about the current state and knowledge of the cost of errors. We demonstrate the existence of a feedback control law that implements risk-aware control and show that this control law can be directly implemented by populations of spiking neurons. Simulated examples of risk-aware control for time-varying cost functions as well as learning of unknown dynamics in a stochastic risky environment are provided.

    The number of website visits, Facebook friends, or Twitter followers that politicians attract varies greatly, but little is known about what drives politicians' online popularity. In this article, we use data from a systematic tracking of congressional candidates' popularity on four web platforms......-seat races tend to attract larger audiences online, as do candidates who are more visible on political blogs. Surprisingly, how intensely candidates are covered in news media, how popular they are in opinion polls, and how much money they spend during the campaign show no significant effect. These findings...... help us understand the dynamics of internet politics, and have wider implications for candidate competition and party politics....

    Energy efficiency is an important design paradigm in Wireless Sensor Networks (WSNs) and its consumption in dynamic environment is even more critical. Duty cycling of sensor nodes is used to address the energy consumption problem. However, along with advantages, duty cycle aware networks introduce some complexities like synchronization and latency. Due to their inherent characteristics, many traditional routing protocols show low performance in densely deployed WSNs with duty cycle awareness, when sensor nodes are supposed to have high mobility. In this paper we first present a three messages exchange Lightweight Random Walk Routing (LRWR) protocol and then evaluate its performance in WSNs for routing low data rate packets. Through NS-2 based simulations, we examine the LRWR protocol by comparing it with DYMO, a widely used WSN protocol, in both static and dynamic environments with varying duty cycles, assuming the standard IEEE 802.15.4 in lower layers. Results for the three metrics, that is, reliability, end-to-end delay, and energy consumption, show that LRWR protocol outperforms DYMO in scalability, mobility, and robustness, showing this protocol as a suitable choice in low duty cycle and dense WSNs.

  3. Programming models for energy-aware systems

    Zhu, Haitao

    Energy efficiency is an important goal of modern computing, with direct impact on system operational cost, reliability, usability and environmental sustainability. This dissertation describes the design and implementation of two innovative programming languages for constructing energy-aware systems. First, it introduces ET, a strongly typed programming language to promote and facilitate energy-aware programming, with a novel type system design called Energy Types. Energy Types is built upon a key insight into today's energy-efficient systems and applications: despite the popular perception that energy and power can only be described in joules and watts, real-world energy management is often based on discrete phases and modes, which in turn can be reasoned about by type systems very effectively. A phase characterizes a distinct pattern of program workload, and a mode represents an energy state the program is expected to execute in. Energy Types is designed to reason about energy phases and energy modes, bringing programmers into the optimization of energy management. Second, the dissertation develops Eco, an energy-aware programming language centering around sustainability. A sustainable program built from Eco is able to adaptively adjusts its own behaviors to stay on a given energy budget, avoiding both deficit that would lead to battery drain or CPU overheating, and surplus that could have been used to improve the quality of the program output. Sustainability is viewed as a form of supply and demand matching, and a sustainable program consistently maintains the equilibrium between supply and demand. ET is implemented as a prototyped compiler for smartphone programming on Android, and Eco is implemented as a minimal extension to Java. Programming practices and benchmarking experiments in these two new languages showed that ET can lead to significant energy savings for Android Apps and Eco can efficiently promote battery awareness and temperature awareness in real

    As part of the Charleston Area Pollution Prevention Partnership (CAPs), studies have been performed to address environmental health issues using various techniques including Geographic Information Systems (GIS) mapping. Most of the mapping has been conducted by academic team members; however, there is a need for more community-based mapping to ensure the sustainability and effectiveness of community-driven efforts to eliminate environmental hazards and health disparities. The emergence of public participatory GIS (PPGIS) has been shown as a way to democratize science, build community capacity, and empower local citizens to address environmental health issues. This article describes the development of the Environmental Justice (EJ) Radar, a PPGIS tool that provides stakeholders in South Carolina with a way to raise environmental awareness and improve citizen participation in local environmental decision-making. We describe the functionality of EJ Radar and discuss feedback received from stakeholders to improve the utility of the PPGIS tool.

Firstly, the hierarchy architecture is adopted to convert this scheduling problem into three subproblems, that is, the task ranking, value task detecting, and energy conservation optimization. Then, the algorithms are designed for the sub-problems, and the solving results are corresponding to feasible solution, efficient solution, and optimization solution of original problem, respectively. This paper makes detailed introduction to the energy-aware optimization strategy, which can rationally adjust airship’s cruising speed based on the distribution of task’s deadline, so as to decrease the total energy consumption caused by cruising activities. Finally, the application results and comparison analysis show that the proposed strategy and algorithm are effective and feasible.

    2014-12-01

    Full Text Available The disruptive innovation of smartphone technology has enabled the development of mobile sensing applications leveraged on specialized sensors embedded in the device. These novel mobile phone applications rely on advanced sensor information processes, which mainly involve raw data acquisition, feature extraction, data interpretation and transmission. However, the continuous accessing of sensing resources to acquire sensor data in smartphones is still very expensive in terms of energy, particularly due to the periodic use of power-intensive sensors, such as the Global Positioning System (GPS receiver. The key underlying idea to design energy-efficient schemes is to control the duty cycle of the GPS receiver. However, adapting the sensing rate based on dynamic context changes through a flexible middleware has received little attention in the literature. In this paper, we propose a novel modular middleware architecture and runtime environment to directly interface with application programming interfaces (APIs and embedded sensors in order to manage the duty cycle process based on energy and context aspects. The proposed solution has been implemented in the Android software stack. It allows continuous location tracking in a timely manner and in a transparent way to the user. It also enables the deployment of sensing policies to appropriately control the sampling rate based on both energy and perceived context. We validate the proposed solution taking into account a reference location-based service (LBS architecture. A cloud-based storage service along with online mobility analysis tools have been used to store and access sensed data. Experimental measurements demonstrate the feasibility and efficiency of our middleware, in terms of energy and location resolution.

    Full Text Available Energy issue is one of the most important problems in wireless sensor networks. They consist of low-power sensor nodes and a few base station nodes. They must be adaptive and efficient in data transmission to sink in various areas. This paper proposes an aware-routing protocol based on clustering and recursive search approaches. The paper focuses on the energy efficiency issue with various measures such as prolonging network lifetime along with reducing energy consumption in the sensor nodes and increasing the system reliability. Our proposed protocol consists of two phases. In the first phase (network development phase, the sensors are placed into virtual layers. The second phase (data transmission is related to routes discovery and data transferring so it is based on virtual-based Classic-RBFS algorithm in the lake of energy problem environments but, in the nonchargeable environments, all nodes in each layer can be modeled as a random graph and then begin to be managed by the duty cycle method. Additionally, the protocol uses new topology control, data aggregation, and sleep/wake-up schemas for energy saving in the network. The simulation results show that the proposed protocol is optimal in the network lifetime and packet delivery parameters according to the present protocols.

    Full Text Available In this article, we advance the concept of “evolutionary awareness,” a metacognitive framework that examines human thought and emotion from a naturalistic, evolutionary perspective. We begin by discussing the evolution and current functioning of the moral foundations on which our framework rests. Next, we discuss the possible applications of such an evolutionarily-informed ethical framework to several domains of human behavior, namely: sexual maturation, mate attraction, intrasexual competition, culture, and the separation between various academic disciplines. Finally, we discuss ways in which an evolutionary awareness can inform our cross-generational activities—which we refer to as “intergenerational extended phenotypes”—by helping us to construct a better future for ourselves, for other sentient beings, and for our environment.

  20. The Awareness of the International Veterinary Profession of Evidence-Based Veterinary Medicine and Preferred Methods of Training.

    2017-03-08

    Evidence-based veterinary medicine (EVM) is an evolving discipline in veterinary medicine so it is important to periodically "benchmark" opinion about EVM across the profession. An international survey to assess veterinarians' awareness of EVM was conducted. Veterinarians were surveyed via an online questionnaire (all countries) or a postal questionnaire (UK only). Participants were asked whether they had heard of EVM, where they had first heard the term, and their preferences of method for receiving continuing professional development (CPD). There were 6310 respondents, of which 4579 (72.5%) worked in the UK and 5384 (85.3%) were clinicians. Veterinarians that had heard of EVM ( n = 5420, 85.9%) were most likely to be clinicians (OR = 4.00; 95% CI: 3.37, 4.75), respondents working in the UK (OR = 1.32; CI: 1.13, 1.54), or respondents with a postgraduate degree or qualification (OR = 1.77; CI: 1.51, 2.08). The most common sources from which respondents had heard of EVM were at vet school or university ( n = 1207, 29.8%), via literature (peer-reviewed papers or other publications) ( n = 1074, 26.5%), and via CPD courses ( n = 564, 13.9%). Most respondents were interested in finding out more about EVM ( n = 4256 of 6173, 69%). The preferred methods of CPD were day or evening seminars ( n = 2992 of 6017, 49.7%), conferences ( n = 1409, 23.4%), and online courses ( n = 524, 8.7%), although the order of preference differed slightly between groups. There appears to be substantial awareness of EVM amongst veterinarians internationally. However, it appears that further training in EVM would be welcomed. Preferences on how CPD in general is received differs between groups, so this should be borne in mind by training providers when formulating a strategy for the dissemination of EVM training across the global profession.

  1. Use of auditory evoked potentials for intra-operative awareness in anesthesia: a consciousness-based conceptual model.

    2015-01-01

    Auditory evoked potentials (AEPs) have been used as a measure of the depth of anesthesia during the intra-operative process. AEPs are classically divided, on the basis of their latency, into first, fast, middle, slow, and late components. The use of auditory evoked potential has been advocated for the assessment of Intra-operative awareness (IOA), but has not been considered seriously enough to universalize it. It is because we have not explored enough the impact of auditory perception and auditory processing on the IOA phenomena as well as on the subsequent psychological impact of IOA on the patient. More importantly, we have seldom tried to look at the phenomena of IOP from the perspective of consciousness itself. This perspective is especially important because many of IOA phenomena exist in the subconscious domain than they do in the conscious domain of explicit recall. Two important forms of these subconscious manifestations of IOA are the implicit recall phenomena and post-operative dreams related to the operation. Here, we present an integrated auditory consciousness-based model of IOA. We start with a brief description of auditory awareness and the factors affecting it. Further, we proceed to the evaluation of conscious and subconscious information processing by auditory modality and how they interact during and after intra-operative period. Further, we show that both conscious and subconscious auditory processing affect the IOA experience and both have serious psychological implications on the patient subsequently. These effects could be prevented by using auditory evoked potential during monitoring of anesthesia, especially the mid-latency auditory evoked potentials (MLAERs). To conclude our model with present hypothesis, we propose that the use of auditory evoked potential should be universal with general anesthesia use in order to prevent the occurrences of distressing outcomes resulting from both conscious and subconscious auditory processing during

    To determine the effects of an adversary's behavior on the defender's accurate and timely detection of network threats. Cyber attacks cause major work disruption. It is important to understand how a defender's behavior (experience and tolerance to threats), as well as adversarial behavior (attack strategy), might impact the detection of threats. In this article, we use cognitive modeling to make predictions regarding these factors. Different model types representing a defender, based on Instance-Based Learning Theory (IBLT), faced different adversarial behaviors. A defender's model was defined by experience of threats: threat-prone (90% threats and 10% nonthreats) and nonthreat-prone (10% threats and 90% nonthreats); and different tolerance levels to threats: risk-averse (model declares a cyber attack after perceiving one threat out of eight total) and risk-seeking (model declares a cyber attack after perceiving seven threats out of eight total). Adversarial behavior is simulated by considering different attack strategies: patient (threats occur late) and impatient (threats occur early). For an impatient strategy, risk-averse models with threat-prone experiences show improved detection compared with risk-seeking models with nonthreat-prone experiences; however, the same is not true for a patient strategy. Based upon model predictions, a defender's prior threat experiences and his or her tolerance to threats are likely to predict detection accuracy; but considering the nature of adversarial behavior is also important. Decision-support tools that consider the role of a defender's experience and tolerance to threats along with the nature of adversarial behavior are likely to improve a defender's overall threat detection.

  3. Computationally Efficient Automatic Coast Mode Target Tracking Based on Occlusion Awareness in Infrared Images.

    Kim, Sohyun; Jang, Gwang-Il; Kim, Sungho; Kim, Junmo

    2018-03-27

    This paper proposes the automatic coast mode tracking of centroid trackers for infrared images to overcome the target occlusion status. The centroid tracking method, using only the brightness information of an image, is still widely used in infrared imaging tracking systems because it is difficult to extract meaningful features from infrared images. However, centroid trackers are likely to lose the track because they are highly vulnerable to screened status by the clutter or background. Coast mode, one of the tracking modes, maintains the servo slew rate with the tracking rate right before the loss of track. The proposed automatic coast mode tracking method makes decisions regarding entering coast mode by the prediction of target occlusion and tries to re-lock the target and resume the tracking after blind time. This algorithm comprises three steps. The first step is the prediction process of the occlusion by checking both matters which have target-likelihood brightness and which may screen the target despite different brightness. The second step is the process making inertial tracking commands to the servo. The last step is the process of re-locking a target based on the target modeling of histogram ratio. The effectiveness of the proposed algorithm is addressed by presenting experimental results based on computer simulation with various test imagery sequences compared to published tracking algorithms. The proposed algorithm is tested under a real environment with a naval electro-optical tracking system (EOTS) and airborne EO/IR system.

    Sun, Chong; Wang, Dong; Lu, Huchuan

    2016-08-01

    In this paper, we present a robust tracking method by exploiting a fragment-based appearance model with consideration of both temporal continuity and discontinuity information. From the perspective of probability theory, the proposed tracking algorithm can be viewed as a two-stage optimization problem. In the first stage, by adopting the estimated occlusion state as a prior, the optimal state of the tracked object can be obtained by solving an optimization problem, where the objective function is designed based on the classification score, occlusion prior, and temporal continuity information. In the second stage, we propose a discriminative occlusion model, which exploits both foreground and background information to detect the possible occlusion, and also models the consistency of occlusion labels among different frames. In addition, a simple yet effective training strategy is introduced during the model training (and updating) process, with which the effects of spatial-temporal consistency are properly weighted. The proposed tracker is evaluated by using the recent benchmark data set, on which the results demonstrate that our tracker performs favorably against other state-of-the-art tracking algorithms.

  6. Constraint-aware interior layout exploration for pre-cast concrete-based buildings

    KAUST Repository

    Liu, Han

    2013-05-03

    Creating desirable layouts of building interiors is a complex task as designers have to manually adhere to various local and global considerations arising from competing practical and design considerations. In this work, we present an interactive design tool to create desirable floorplans by computationally conforming to such design constraints. Specifically, we support three types of constraints: (i) functional constraints such as number of rooms, connectivity among the rooms, target room areas, etc.; (ii) design considerations such as user modifications and preferences, and (iii) fabrication constraints such as cost and convenience of manufacturing. Based on user specifications, our system automatically generates multiple floor layouts with associated 3D geometry that all satisfy the design specifications and constraints, thus exposing only the desirable family of interior layouts to the user. In this work, we focus on pre-cast concrete-based constructions, which lead to interesting discrete and continuous optimization possibilities. We test our framework on a range of complex real-world specifications and demonstrate the control and expressiveness of the exposed design space relieving the users of the task of manually adhering to non-local functional and fabrication constraints. © 2013 Springer-Verlag Berlin Heidelberg.

    2014-01-01

    Full Text Available We compare the performance of three base station management schemes on three different network topologies. In addition, we explore the effect of offloading traffic to heterogeneous femtocell layer upon energy savings taking into account the increase of base station switch-off time intervals. Fairness between mobile operator and femtocell owners is maintained since current femtocell technologies present flat power consumption curves with respect to served traffic. We model two different user-to-femtocell association rules in order to capture realistic and maximum gains from the heterogeneous network. To provide accurate findings and a holistic overview of the techniques, we explore a real urban district where channel estimations and power control are modeled using deterministic algorithms. Finally, we explore energy efficiency metrics that capture savings in the mobile network operator, the required watts per user and watts per bitrate. It is found that the newly established pseudo distributed management scheme is the most preferable solution for practical implementations and together with the femotcell layer the network can handle dynamic load control that is regarded as the basic element of future demand response programs.

    Full Text Available In the 1970s, a radical adult education movement in Latin America, operating outside the state and engaging in what it called 'popular education', sparked world-wide interest in its educational theory and practice. More recently, with a change in state formations in Latin America, the movement has reconsidered its potential relationship with the state. Though Europe has its own history of popular education, some have argued that advanced economies and welfare states co-opted any strong independent educational movement: today popular education is more likely to take place 'within and against' the state, rather than outside it. Based on literature review, personal interviews and site visits, this article (a discusses what is understood by popular education (b outlines the development of popular education in Latin America, examining its relationship with different types of state (c considers differences between Latin America and Europe and what, if anything, popular educators in the two regions might learn from each other.

    Full Text Available Nowadays, large amounts of tourism information and services are available over the Web. This makes it difficult for the user to search for some specific information such as selecting a tour in a given city as an ordered set of points of interest. Moreover, the user rarely knows all his needs upfront and his preferences may change during a recommendation process. The user may also have a limited number of initial ratings and most often the recommender system is likely to face the well-known cold start problem. The objective of the research presented in this paper is to introduce a hybrid interactive context-aware tourism recommender system that takes into account user’s feedbacks and additional contextual information. It offers personalized tours to the user based on his preferences thanks to the combination of a case based reasoning framework and an artificial neural network. The proposed method has been tried in the city of Tehran in Iran. The results show that the proposed method outperforms current artificial neural network methods and combinations of case based reasoning with k-nearest neighbor methods in terms of user effort, accuracy, and user satisfaction.

    Conventional approaches to predict the future popularity of products are mainly based on extrapolation of their current popularity, which overlooks the hidden microscopic information under the macroscopic trend. Here, we study diffusion processes on consumer-product and citation networks to exploit the hidden microscopic information and connect consumers to their potential purchase, publications to their potential citers to obtain a prediction for future item popularity. By using the data obtained from the largest online retailers including Netflix and Amazon as well as the American Physical Society citation networks, we found that our method outperforms the accurate short-term extrapolation and identifies the potentially popular items long before they become prominent.

  12. WQM: An Aggregation-aware Queue Management Scheme for IEEE 802.11n based Networks

    Choosing the right buffer size in Wi-Fi networks is challenging due to the dynamic nature of the wireless environment. Over buffering or \\'bufferbloat\\' may produce unacceptable end-to-end delays, while static small buffers may limit the performance gains that can be achieved with various 802.11n enhancements, such as frame aggregation. We propose WQM, a queue management scheme customized for wireless networks. WQM adapts the buffer size based on measured link characteristics and network load. Furthermore, it accounts for aggregate length when deciding about the optimal buffer size. We implement WQM on Linux and evaluate it on a wireless testbed. WQM reduces the end-to-end delay by up to 8x compared to Linux default buffer size, and 2x compared to CoDel, the state-of-the-art bufferbloat solution, while achieving comparable network goodput. Further, WQM improves fairness as it limits the ability of a single flow to saturate the buffer.

  14. A Socially Aware Routing Based on Local Contact Information in Delay-Tolerant Networks

    2014-01-01

    Full Text Available In delay-tolerant networks, network topology changes dynamically and there is no guarantee of continuous connectivity between any two nodes. These features make DTN routing one of important research issues, and the application of social network metrics has led to the design of recent DTN routing schemes. In this paper, we propose an efficient routing scheme by using a node’s local contact history and social network metrics. Each node first chooses a proper relay node based on the closeness to the destination node. A locally computed betweenness centrality is additionally utilized to enhance the routing efficiency. Through intensive simulation, we finally demonstrate that our algorithm performs efficiently compared to the existing epidemic or friendship routing scheme.

  15. Spatiotemporal Context Awareness for Urban Traffic Modeling and Prediction: Sparse Representation Based Variable Selection.

    Directory of Open Access Journals (Sweden)

    Su Yang

    Full Text Available Spatial-temporal correlations among the data play an important role in traffic flow prediction. Correspondingly, traffic modeling and prediction based on big data analytics emerges due to the city-scale interactions among traffic flows. A new methodology based on sparse representation is proposed to reveal the spatial-temporal dependencies among traffic flows so as to simplify the correlations among traffic data for the prediction task at a given sensor. Three important findings are observed in the experiments: (1 Only traffic flows immediately prior to the present time affect the formation of current traffic flows, which implies the possibility to reduce the traditional high-order predictors into an 1-order model. (2 The spatial context relevant to a given prediction task is more complex than what is assumed to exist locally and can spread out to the whole city. (3 The spatial context varies with the target sensor undergoing prediction and enlarges with the increment of time lag for prediction. Because the scope of human mobility is subject to travel time, identifying the varying spatial context against time lag is crucial for prediction. Since sparse representation can capture the varying spatial context to adapt to the prediction task, it outperforms the traditional methods the inputs of which are confined as the data from a fixed number of nearby sensors. As the spatial-temporal context for any prediction task is fully detected from the traffic data in an automated manner, where no additional information regarding network topology is needed, it has good scalability to be applicable to large-scale networks.

    Full Text Available The main goal of Ambient Assisted Living solutions is to provide assistive technologies and services in smart environments allowing elderly people to have high quality of life. Since 3D sensing technologies are increasingly investigated as monitoring solution able to outperform traditional approaches, in this work a noninvasive monitoring platform based on 3D sensors is presented providing a wide-range solution suitable in several assisted living scenarios. Detector nodes are managed by low-power embedded PCs in order to process 3D streams and extract postural features related to person’s activities. The feature level of details is tuned in accordance with the current context in order to save bandwidth and computational resources. The platform architecture is conceived as a modular system suitable to be integrated into third-party middleware to provide monitoring functionalities in several scenarios. The event detection capabilities were validated by using both synthetic and real datasets collected in controlled and real-home environments. Results show the soundness of the presented solution to adapt to different application requirements, by correctly detecting events related to four relevant AAL services.

    2012-01-01

    Full Text Available Mental care has become crucial with the rapid growth of economy and technology. However, recent movements, such as green technologies, place more emphasis on environmental issues than on mental care. Therefore, this study presents an emerging technology called orange computing for mental care applications. Orange computing refers to health, happiness, and physiopsychological care computing, which focuses on designing algorithms and systems for enhancing body and mind balance. The representative color of orange computing originates from a harmonic fusion of passion, love, happiness, and warmth. A case study on a human-machine interactive and assistive system for emotion care was conducted in this study to demonstrate the concept of orange computing. The system can detect emotional states of users by analyzing their facial expressions, emotional speech, and laughter in a ubiquitous environment. In addition, the system can provide corresponding feedback to users according to the results. Experimental results show that the system can achieve an accurate audiovisual recognition rate of 81.8% on average, thereby demonstrating the feasibility of the system. Compared with traditional questionnaire-based approaches, the proposed system can offer real-time analysis of emotional status more efficiently.

  1. Creating awareness of an evidence-based approach to urban design.

    Paul, Abhijit

    2012-01-01

    Urban Design is a framework of urban studies that helps to understand the behavior of a city and, thus, the reasoning of its formation in a multidisciplinary way. Appropriate design policies help to attain solutions to urban problems by minimizing development impacts and by optimizing socioeconomic values of inner-city environments. However, development impacts and socio-economic values of an urban built-environment have a strong relationship with its spatial and organizational characteristics. That is, the pattern of the space organization itself helps to understand how the space is being used, and perhaps, what changes will make the space more interactive, usable, and environment-friendly. This study explores the spatial and organizational characteristics of urban morphology in evaluating urban development impacts by using the theory of space syntax. Conclusions suggest that space syntax simulates the likely effects of urban development solutions and, consequently, helps to evaluate urban design policies with data-based evidence before making recommendations for capital investments.

  2. Resource Aware Sensor-to-Actor Allocation Framework for WSANs Based on Voronoi Cells Theory

    Directory of Open Access Journals (Sweden)

    Sofia Maria Dima

    2017-01-01

    Full Text Available Wireless sensor and actor networks (WSANs have emerged as a promising research field and have been applied in a wide variety of application domains due to their capability of environment monitoring, event data processing, and decision-making by aiming at performing appropriate actions interacting with the environment. Coordination mechanisms among nodes and actors are a critical research challenge pertaining to the optimum allocation of sensors to a particular actor. Although efforts related to the node-to-actor coordination problem have been presented in the current literature, there is a significant oversight regarding critical characteristics such as the heterogeneous capabilities of the actors as well as the network’s heterogeneous density. In this paper, aiming to address such shortcomings, we introduce the term Actor Service Capacity, which indicates the ability of an actor to serve a particular number of nodes. We also propose a novel node-to-actor coordination algorithm, based on the Voronoi tessellation, aiming to guarantee that the number of nodes, allocated to each actor, will not exceed its capabilities. Furthermore, a set of selection techniques are proposed so as to be applied on the coordination framework. Respective evaluation analysis offers useful conclusions and highlights the importance and the advantages of the proposed algorithm.

  5. Biosurveillance enterprise for operational awareness, a genomic-based approach for tracking pathogen virulence.

    Valdivia-Granda, Willy A

    2013-11-15

    To protect our civilians and warfighters against both known and unknown pathogens, biodefense stakeholders must be able to foresee possible technological trends that could affect their threat risk assessment. However, significant flaws in how we prioritize our countermeasure-needs continue to limit their development. As recombinant biotechnology becomes increasingly simplified and inexpensive, small groups, and even individuals, can now achieve the design, synthesis, and production of pathogenic organisms for offensive purposes. Under these daunting circumstances, a reliable biosurveillance approach that supports a diversity of users could better provide early warnings about the emergence of new pathogens (both natural and manmade), reverse engineer pathogens carrying traits to avoid available countermeasures, and suggest the most appropriate detection, prophylactic, and therapeutic solutions. While impressive in data mining capabilities, real-time content analysis of social media data misses much of the complexity in the factual reality. Quality issues within freeform user-provided hashtags and biased referencing can significantly undermine our confidence in the information obtained to make critical decisions about the natural vs. intentional emergence of a pathogen. At the same time, errors in pathogen genomic records, the narrow scope of most databases, and the lack of standards and interoperability across different detection and diagnostic devices, continue to restrict the multidimensional biothreat assessment. The fragmentation of our biosurveillance efforts into different approaches has stultified attempts to implement any new foundational enterprise that is more reliable, more realistic and that avoids the scenario of the warning that comes too late. This discussion focus on the development of genomic-based decentralized medical intelligence and laboratory system to track emerging and novel microbial health threats in both military and civilian settings and

    Some 60 years after introduction of the Papanicolaou smear worldwide, cervical cancer remains a burden in developing countries where >85% of world new cases and deaths occur, suggesting a failure to establish comprehensive cervical-cancer control programs. Effective interventions are available to control cervical cancer but are not all affordable in low-income settings. Disease awareness saves lives by risk-reduction as witnessed in reducing mortality of HIV/AIDS and smoking-related cancers. We initiated a community-based awareness program on cervical cancer in two low-income Muslim Uyghur townships in Kashi (Kashgar) Prefecture, Xinjiang, China in 2008. The education involved more than 5,000 women from two rural townships and awareness was then evaluated in 2010 and 2011, respectively, using a questionnaire with 10 basic knowledge questions on cervical cancer. Demographic information was also collected and included in an EpiData database. A 10-point scoring system was used to score the awareness. The effectiveness and feasibility of the program were evaluated among 4,475 women aged 19-70 years, of whom >92% lived on/ below US$1.00/day. Women without prior education showed a poor average awareness rate of 6.4% (164/2,559). A onetime education intervention, however, sharply raised the awareness rate by 4-fold to 25.5% (493/1,916). Importantly, low income and illiteracy were two reliable factors affecting awareness before or after education intervention. Education intervention can significantly raise the awareness of cervical cancer in low-income women. Economic development and compulsory education are two important solutions in raising general disease awareness. We propose that implementing community-based awareness programs against cervical cancer is realistic, locally affordable and sustainable in low-income countries, which may save many lives over time and, importantly, will facilitate the integration of comprehensive programs when feasible. In this context

    2013-03-01

    Full Text Available Wireless Sensor Networks (WSNs demand reliable and energy efficient paths for critical information delivery to sink node from an event occurrence node. Multipath routing facilitates reliable data delivery in case of critical information. This paper proposes an event triggered multipath routing in WSNs by employing a set of static and mobile agents. Every sensor node is assumed to know the location information of the sink node and itself. The proposed scheme works as follows: (1 Event node computes the arbitrary midpoint between an event node and the sink node by using location information. (2 Event node establishes a shortest path from itself to the sink node through the reference axis by using a mobile agent with the help of location information; the mobile agent collects the connectivity information and other parameters of all the nodes on the way and provides the information to the sink node. (3 Event node finds the arbitrary location of the special (middle intermediate nodes (above/below reference axis by using the midpoint location information given in step 1. (4 Mobile agent clones from the event node and the clones carry the event type and discover the path passing through special intermediate nodes; the path above/below reference axis looks like an arc. While migrating from one sensor node to another along the traversed path, each mobile agent gathers the node information (such as node id, location information, residual energy, available bandwidth, and neighbors connectivity and delivers to the sink node. (5 The sink node constructs a partial topology, connecting event and sink node by using the connectivity information delivered by the mobile agents. Using the partial topology information, sink node finds the multipath and path weight factor by using link efficiency, energy ratio, and hop distance. (6 The sink node selects the number of paths among the available paths based upon the criticalness of an event, and (7 if the event is non

    2016-06-01

    Full Text Available User experience remains a crucial consideration when assessing the successfulness of information visualization systems. The theory of affordances provides a robust framework for user experience design. In this article, we demonstrate a design case that employs an affordance-based framework and evaluate the information visualization display design. SolarWheels is an interactive information visualization designed for large display walls in computer network control rooms to help cybersecurity analysts become aware of network status and emerging issues. Given the critical nature of this context, the status and performance of a computer network must be precisely monitored and remedied in real time. In this study, we consider various aspects of affordances in order to amplify the user experience via visualization and interaction design. SolarWheels visualizes the multilayer multidimensional computer network issues with a series of integrated circular visualizations inspired by the metaphor of the solar system. To amplify user interaction and experience, the system provides a three-zone physical interaction that allows multiple users to interact with the system. Users can read details at different levels depending on their distance from the display. An expert evaluation study, based on a four-layer affordance framework, was conducted to assess and improve the interactive visualization design.

    Team situational awareness (TSA) is critical for effective teamwork and supports dynamic decision making in unpredictable, time-pressured situations. Simulation provides a platform for developing and assessing TSA, but these efforts are limited by suboptimal measurement approaches. The objective of this study was to develop and evaluate a novel approach to TSA measurement in interprofessional emergency medicine (EM) teams. We performed a multicenter, prospective, simulation-based observational study to evaluate an approach to TSA measurement. Interprofessional emergency medical teams, consisting of EM resident physicians, nurses, and medical students, were recruited from the University of Washington (Seattle, WA) and Wayne State University (Detroit, MI). Each team completed a simulated emergency resuscitation scenario. Immediately following the simulation, team members completed a TSA measure, a team perception of shared understanding measure, and a team leader effectiveness measure. Subject matter expert reviews and pilot testing of the TSA measure provided evidence of content and response process validity. Simulations were recorded and independently coded for team performance using a previously validated measure. The relationships between the TSA measure and other variables (team clinical performance, team perception of shared understanding, team leader effectiveness, and team experience) were explored. The TSA agreement metric was indexed by averaging the pairwise agreement for each dyad on a team and then averaging across dyads to yield agreement at the team level. For the team perception of shared understanding and team leadership effectiveness measures, individual team member scores were aggregated within a team to create a single team score. We computed descriptive statistics for all outcomes. We calculated Pearson's product-moment correlations to determine bivariate correlations between outcome variables with two-tailed significance testing (p teams (n = 41

    Sex trafficking is a contemporary issue in both developed and developing countries. The number of trafficked women and young girls has increased globally. Females aged 18-25 are the most targeted group of trafficking. Although the problem is evident in Ethiopia, there are no studies that explored sex trafficking awareness among females. Therefore, the aim of this study was to assess sex trafficking awareness and associated factors among youth females in Bahir Dar town, North-West Ethiopia. A community based cross-sectional study design was employed to collect data from February 1st-30th 2012 from a total of 417 youth females. The participants in the study were selected using systematic random sampling techniques. A structured Amharic questionnaire was used to collect data. Data were entered, cleaned and analyzed using SPSS 16.0. Descriptive statistics were used to describe data. Logistic regression analysis was used to identify factors associated with sex trafficking awareness. Two hundred forty-nine (60%) of the participants reported that they had heard or read about sex trafficking. Television (64%), friends (46%) and radio (39%) were the most frequently mentioned sources of information about sex trafficking. About 87% and 74% of the participants mentioned friends and brokers respectively as mediators of sex trafficking. Having TV at home (AOR = 2. 19, 95% CI: 1.31-3.67), completing grade 10 or more (AOR = 2. 22, 95% CI: 1.18-4.17), taking training on gender issues (AOR = 3. 59, 95% CI: 2.11-6.10) and living together with parents (AOR = 3. 65, 95% CI: 1.68-7.93) were factors found associated with sex trafficking awareness. In this study, sex trafficking awareness was low among youth females. Having TV at home, living together with someone and being trained on gender issues were predictors of sex trafficking awareness. Therefore, providing education about sex trafficking will help to increase sex trafficking awareness among youth females.

    Directory of Open Access Journals (Sweden)

    Apangshu Das

    2016-01-01

    Full Text Available The increased number of complex functional units exerts high power-density within a very-large-scale integration (VLSI chip which results in overheating. Power-densities directly converge into temperature which reduces the yield of the circuit. An adverse effect of power-density reduction is the increase in area. So, there is a trade-off between area and power-density. In this paper, we introduce a Shared Reed-Muller Decision Diagram (SRMDD based on fixed polarity AND-XOR decomposition to represent multioutput Boolean functions. By recursively applying transformations and reductions, we obtained a compact SRMDD. A heuristic based on Genetic Algorithm (GA increases the sharing of product terms by judicious choice of polarity of input variables in SRMDD expansion and a suitable area and power-density trade-off has been enumerated. This is the first effort ever to incorporate the power-density as a measure of temperature estimation in AND-XOR expansion process. The results of logic synthesis are incorporated with physical design in CADENCE digital synthesis tool to obtain the floor-plan silicon area and power profile. The proposed thermal-aware synthesis has been validated by obtaining absolute temperature of the synthesized circuits using HotSpot tool. We have experimented with 29 benchmark circuits. The minimized AND-XOR circuit realization shows average savings up to 15.23% improvement in silicon area and up to 17.02% improvement in temperature over the sum-of-product (SOP based logic minimization.

    Full Text Available Currently, wireless body area networks (WBANs are effectively used for health monitoring services. However, in cases where WBANs are densely deployed, interference among WBANs can cause serious degradation of network performance and reliability. Inter-WBAN interference can be reduced by scheduling the communication links of interfering WBANs. In this paper, we propose an interference-aware traffic-priority-based link scheduling (ITLS algorithm to overcome inter-WBAN interference in densely deployed WBANs. First, we model a network with multiple WBANs as an interference graph where node-level interference and traffic priority are taken into account. Second, we formulate link scheduling for multiple WBANs as an optimization model where the objective is to maximize the throughput of the entire network while ensuring the traffic priority of sensor nodes. Finally, we propose the ITLS algorithm for multiple WBANs on the basis of the optimization model. High spatial reuse is also achieved in the proposed ITLS algorithm. The proposed ITLS achieves high spatial reuse while considering traffic priority, packet length, and the number of interfered sensor nodes. Our simulation results show that the proposed ITLS significantly increases spatial reuse and network throughput with lower delay by mitigating inter-WBAN interference.

    Students, the future Information and Communication Technology (ICT) professionals, are often perceived to have little understanding of the ethical issues associated with the use of ICTs. There is a growing recognition that the moral issues associated with the use of the new technologies should be brought to the attention of students. Furthermore, they should be encouraged to explore and think more deeply about the social and legal consequences of the use of ICTs. This paper describes the development of a tool designed to raise students' awareness of the social impact of ICTs. The tool offers guidance to students undertaking computing and computer-related courses when considering the social, legal and professional implications of the actions of participants in situations of ethical conflict. However, unlike previous work in this field, this tool is not based on an artificial intelligence paradigm. Aspects of the theoretical basis for the design of the tool and the tool's practical development are discussed. Preliminary results from the testing of the tool are also discussed.

    Full Text Available Recommender systems help users faced with the problem of information overflow and provide personalized recommendations. Social networks are used for providing variety of business or social activities, or sometimes a combination of both. In this paper, by considering social network of users and according to users’ context and items, a new method is introduced that is based on trust and context aware for recommender systems in social networks. The purpose of this paper is to create a recommender system which increases precision of predicted ratings for all users especially for cold start users. In the proposed method, walking on web of trust is done by neighbor users for finding rating of similar items and users’ preference is gotten of items’ context. The results show that suitable recommendation with user’s context is provided by using this method. Also, this system can increase precision of predicted rating for all users and cold starts too and however, do not decrease the rating’s coverage.

    Full Text Available With the popularization of smartphones, location-based services are increasingly part of everyday live. People use their cell phones to find nearby restaurants, friends in the vicinity, and track their children. Although location-based services have received sparse attention from mobile communications cholars to date, the ability of locating people and things with one’s cell phone is not new. Since the removal of GPS signal degradation in 2000, artists and researchers have been exploring how location-awareness influences mobility, spatiality and sociability. Besides exploring the historical antecedents of today’s location-based services, this paper focuses on the main social issues that emerge when location-aware technologies leave the strict domain of art and research and become part of everyday life: locational privacy, sociability, and spatiality. Finally, this paper addresses two main topics that future mobile communication research that focus on location-awareness should take into consideration: a shift in the meaning of location, and the adoption and appropriation of location-aware technologies in the global south.

    2009-01-01

    This discussion of the relations between folklore and popular medicine in the Amazon takes Canuto Azevedo's story "Filhos do boto" (Children of the porpoise) as an analytical reference point. Replete with elements of cultural reality, folk tales can serve as historical testimonies expressing clashes between different traditions. Folk records are fruit of what is often a quarrelsome dialogue between folklorists, social scientists, physicians, and pajés and their followers, and their analysis should take into account the conditions under which they were produced. Based on the imaginary attached to the figure of the porpoise--a seductive creature with healing powers--the article explores how we might expand knowledge of popular medicine as practiced in the Amazon, where the shamanistic rite known as pajelança cabocla has a strong presence.

    Full Text Available Abstract Background Public knowledge of the association between alcohol and cancer is reported to be low. We aimed to provide up-to-date evidence for England regarding awareness of the link between alcohol and different cancers and to determine whether awareness differs by demographic characteristics, alcohol use, and geographic region. Methods A representative sample of 2100 adults completed an online survey in July 2015. Respondents were asked to identify which health outcomes, including specific cancers, may be caused by alcohol consumption. Logistic regressions explored whether demographic, alcohol use, and geographic characteristics predicted correctly identifying alcohol-related cancer risk. Results Unprompted, 12.9% of respondents identified cancer as a potential health outcome of alcohol consumption. This rose to 47% when prompted (compared to 95% for liver disease and 73% for heart disease. Knowledge of the link between alcohol and specific cancers varied between 18% (breast and 80% (liver. Respondents identified the following cancers as alcohol-related where no such evidence exists: bladder (54%, brain (32%, ovarian (17%. Significant predictors of awareness of the link between alcohol and cancer were being female, more highly educated, and living in North-East England. Conclusion There is generally low awareness of the relationship between alcohol consumption and cancer, particularly breast cancer. Greater awareness of the relationship between alcohol and breast cancer in North-East England, where a mass media campaign highlighted this relationship, suggests that population awareness can be influenced by social marketing.

  8. Situation awareness for UAV equipped with image/video understanding system based on network-symbolic models

    Situation awareness is an important factor in the effectiveness of aerial missions. One of the major problems with the UAV is that human operators lack situation awareness. Limited bandwidth does not allow telepresence to a degree, which gives the same level of situation awareness that pilots of regular airplanes have. The best solution would be to equip UAV with a "situation awareness" system that in the real time provides operators with the information necessary for effective mission control and decision making, and allows effective supervisory control of the UAV. Vision in advanced creatures is a component of situation awareness, navigation and planning systems. Fast information processing and decision making requires reduction of informational and computational complexities. The brain achieves this goal using implicit symbolic coding, hierarchical compression, and selective processing of visual information. The Network-Symbolic representation, in which both systematic structural/logical methods and neural/statistical methods are the parts of a single mechanism, converts visual information into relational Network-Symbolic knowledge models, effectively resolving ambiguity and uncertainty in the visual information, and avoiding artificial precise computations of 3-dimensional models. The UAV equipped with such smart vision, will have a situation awareness system that gives operators better control over aircraft and significantly improves surveillance and reconnaissance capabilities.

  9. Popular democracy and waste management

    Wallis, L.R.

    1986-01-01

    The US has moved from representative democracy to popular democracy and public scrutiny is unrelenting. Any hope of success on their part in resolving the nuclear waste question hinges on their ability to condition themselves to operate in a popular democracy environment. Those opposed to the siting of high- and low-level waste repositories have already developed a set of recurring themes: (1) the siting criteria are fatally flawed; (2) the criteria are not adequate; (3) the process is driven by politics not science; (4) unrealistic deadlines lead to dangerous shortcuts; (5) transportation experience is lacking; (6) the scientific community does not really know how to dispose of the wastes. They must continue to tell the public that if science has brought us problems, then the answer can be only more knowledge - not less. Failure by their profession to recognize that popular democracy is a fact and that nuclear issues need to be addressed in humanistic terms raises the question of whether America is philosophically suited for the expanded use of nuclear power in the future - or for that matter for leadership in the world of tomorrow.

    Full Text Available Online news reading has become a widely popular way to read news articles from news sources around the globe. With the enormous amount of news articles available, users are easily overwhelmed by information of little interest to them. News recommender systems help users manage this flood by recommending articles based on user interests rather than presenting articles in order of their occurrence. We present our research on developing personalized news recommendation system with the help of a popular micro-blogging service, “Twitter.” News articles are ranked based on the popularity of the article identified from Twitter’s public timeline. In addition, users construct profiles based on their interests and news articles are also ranked based on their match to the user profile. By integrating these two approaches, we present a hybrid news recommendation model that recommends interesting news articles to the user based on their popularity as well as their relevance to the user profile.

    Indian women with breast cancer are usually diagnosed in advanced stages leading to poor survival. Improving breast awareness and increasing access to early diagnosis and adequate treatment has been advocated for breast cancer control. We implemented a program to increase awareness on breast cancer and access to its early detection in an occupational health care scheme in Mumbai, India. Breast awareness brochures were mailed annually between June 2013 and June 2016 to a cohort of 22,500 eligible women aged 30-69 years old receiving universal health care from an occupational health care scheme comprising of primary health centres and a referral secondary care hospital in Mumbai. Women with suspected breast cancers were provided with diagnostic investigations and treatment. Socio-demographic information and tumour characteristics were compared between the breast awareness pre-intervention period (Jan 2005-May 2013) and the breast awareness intervention period after four rounds of mailers (June 2013-June 2016). The proportion of women with early tumours and axillary lymph node negative cancers increased from 74% to 81% and 46% to 53% respectively, between the two periods. While the proportion of patients receiving breast conserving surgery increased from 39% to 51%, the proportion receiving chemotherapy decreased from 84% to 56%. Interim results following efforts to improve breast awareness and access to care in a cohort of women in an occupational health care scheme indicate early detection and more conservative treatment of breast cancers. Creating awareness and improving access to care may result in cancer down-staging. Copyright © 2016 Elsevier Ltd. All rights reserved.

  15. Energy awareness

    Energy Technology Data Exchange (ETDEWEB)

    1977-01-01

    The objective of the Symposium for Public Awareness on Energy was to provide an information exchange among the members of the technical community and the public, civic, fraternal, service, and labor organizations on timely energy-related issues. The 1977 symposium was oriented toward state and local governmental officials in the southeastern states. Since it is these officials who have the responsibility for the development and actualization of local energy strategies, the program was directed toward providing information which would be of help to them in considering energy plans. The symposium presentations featured speakers who are recognized in many facets of the energy field. A variety of views were expressed and a number of policy alternatives were suggested. It is hoped that the presentations provided the motivation for the audience to return to their respective communities with a new and expanded perspective regarding energy issues and policies. The private and public organizations represented at the symposium can continue to provide pertinent information to those who are interested. A separate abstract was prepared for each of the 9 presentations.

    Full Text Available Abstract Background Both diabetic and non-diabetic end stage renal disease (ESRD are more common among Canadian First Nations people than among the general Canadian population. The purpose of this research was to determine the prevalence of and risk factors for albuminuria in a Canadian First Nation population at high risk for ESRD and dialysis. Methods Data from a community-based screening study of 483 residents of a Plains Ojibway First Nation in Manitoba was used. Participants provided random urine samples. Proteinuria was defined as any dipstick positive for protein (≥1 g/L or those with ACR in the macroalbuminuric range (≥30 mg/mmol on at least one sample. Microalbuminuria was defined as ACR ≥2 mg/mmol for males and ≥2.8 mg/mmol for females. Other measures included fasting glucose, haemoglobin A1c, triglycerides, cholesterol, blood pressure, height, weight and waist and hip circumferences. Results Twenty percent of study participants had albuminuria, (5% proteinuria and 15% microalbuminuria. Of participants with diabetes, 42% (56/132 had albuminuria compared to 26% (7/27 among those with impaired fasting glucose and 10% (30/303 among those with normal glucose tolerance. Only 5.3% of those with albuminuria were aware of any degree of renal disease. In a multivariate logistic regression, independent associations with albuminuria were male gender [p = 0.002], increasing fasting glucose [p Conclusions The independent association between BMI and albuminuria has not been previously reported among indigenous populations. There is a high prevalence of albuminuria in this Canadian First Nation population; the high proportion of patients with diabetes and undiagnosed kidney disease demonstrates the need for screening, education and intervention to halt the progression and development of albuminuria and ultimately ESRD and CVD.

    2006-03-01

    MOTIVATION & PURPOSE: This informal two day workshop is intended to bring together astronomers who monitor the sky for transient phenomena - a field which is poised to take off in the optical band, thanks to the exponential growth in the availability of giga pixel detectors, rapid computing and communication. For somewhat similar technological reasons, decimeter and decameter radio astronomy is also poised to grow in this area. The workshop will focus on astronomical opportunities with ongoing searches and discuss the possibilities with planned facilities in the near term. We hope to rapidly review the status of 'popular' sources (e.g. GRB afterglows, Supernovae, Machos), less popular events (e.g. Novae, geysers and gushers) and then move onto 'odd' but not hopelessly rare events. The spirit is to anticipate some of the discoveries by extending the astrophysical parameter space of known (or knowable) classes of transients. This workshop is part of the ongoing KITP Program "The Supernova Gamma Ray Burst Connection" and has received funding Los Alamos National Laboratory. We will follow the well honed KITP tradition of having fewer talks at the expense of long discussions. All talks will be recorded (per KITP tradition) and made available on the web for enjoyment, education and posterity. In lieu of a traditional poster sessions with old-fashioned easels we offer the Virtual Presence (organized by J. Bloom).

  18. Value-Based and Context-Aware Selection of Software-Service Bundles: A Capability Based Method

    Directory of Open Access Journals (Sweden)

    Jānis Grabis

    2017-04-01

    Full Text Available In many application areas, vendors offer to their clients combinations of software products and services, which can be considered as software-service bundles. The clients select a combination of software product and associated service best suited to their individual requirements and circumstances. The bundle usually has to be configured by the vendor to fit the specific situation of the client. When circumstances change, the software-service bundle or its configuration need adaptation. The article proposes a method helping clients to select the most appropriate combination or configuration. The method is based on information sharing between the vendor and client and also supports the continuous improvement of the solution in response to changing circumstances. The method applies principles and techniques of the Capability Driven Development to specify performance objectives and contextual factors affecting delivery of a software-service bundle. Application of the method is shown using an illustrative case of a data processing service from utility industries.

    Full Text Available This paper examines Dickens’s descriptions of public executions in his letters and early journalism as a context in which to read the final scene of 'A Tale of Two Cities' (1859. It argues that despite his traumatised responses to public hangings, Dickens is able to use the site of the scaffold to articulate some fundamental human fears and dispositions. The paper compares Dickens’s response to the horrors of the French Revolution with Carlyle’s, and shows throughout how Dickens firmly repudiates Trollope's somewhat rueful dismissal of him as ‘Mr Popular Sentiment’.

    Full Text Available Background and Objectives: Menopause, the beginning of a new era in the life of a woman, like all the other stages of life can create some problems, which threaten the women's health. The aim of this study was to examine the effects of education on the awareness of female health volunteers about menopause in the city of Kashan based on the health promotion model in 2016. Materials and Methods: In this semi-experimental study, 280 female health volunteers in the cities of Kashan and Aran Bidgol were selected by simple random sampling in 2016. The health volunteers' knowledge of menopause was compared before and 6 months after the training. The theoretical framework used in this study was the structures of Pender's health promotion model. Data were collected through a questionnaire and analyzed using correlation tests and regression analysis with the SPSS software. Results: The results showed that the mean age of the participants was 30.05 ± 5.17 years (age range, 18–43. The mean score of knowledge before training was 7.6 ± 3.75 and after the intervention was 7.81 ± 6.4, which was increased. There was a significant difference between the mean scores of knowledge before and after the training (P < 0.001 and t = 33.5. The results showed a significant difference in the mean scores of the health promotion model before and after the training (P = 0.05. Conclusion: The results of the present study showed the positive impact of education based on the health promotion model on the knowledge of the volunteers about menopause. It is recommended that some training and research programs be performed to select the optimal training methods for volunteers, and strengthen their scientific knowledge and empower them. Given that the health volunteers have a close relationship with the community, training them can change the health behaviors, reduce the cost of healthcare, and improve the health status of the community.

    2017-08-01

    Herein we describe a methodology for developing a game-based intervention to raise awareness of Chlamydia and other sexually transmitted infections among youth in Boston's underserved communities. We engaged in three design-based experiments. These utilized mixed methods, including playtesting and assessment methods, to examine the overall effectiveness of the game. In this case, effectiveness is defined as (1) engaging the target group, (2) increasing knowledge about Chlamydia, and (3) changing attitudes toward Chlamydia testing. These three experiments were performed using participants from different communities and with slightly different versions of the game, as we iterated through the design/feedback process. Overall, participants who played the game showed a significant increase in participants' knowledge of Chlamydia compared with those in the control group (P = 0.0002). The version of the game, including elements specifically targeting systemic thinking, showed significant improvement in participants' intent to get tested compared with the version of the game without such elements (Stage 2: P > 0.05; Stage 3: P = 0.0045). Furthermore, during both Stage 2 and Stage 3, participants showed high levels of enjoyment, mood, and participation and moderate levels of game engagement and social engagement. During Stage 3, however, participants' game engagement (P = 0.0003), social engagement (P = 0.0003), and participation (P = 0.0003) were significantly higher compared with those of Stage 2. Thus, we believe that motivation improvements from Stage 2 to 3 were also effective. Finally, participants' overall learning effectiveness was correlated with their prepositive affect (r = 0.52) and their postproblem hierarchy (r = -0.54). The game improved considerably from its initial conception through three stages of iterative design and feedback. Our assessment methods for each stage targeted and integrated learning, health, and engagement

    2011-12-01

    A simple and efficient protocol has been developed for high frequency plant regeneration through callus cultures derived from leaf bases of abiotic stress sensitive Asian indica rice variety IR 64. Leaf base segments (4-5 mm diameter) were obtained from 6-day-old dark grown seedlings germinated on halfstrength Murashige and Skoog medium and cultured on MS medium supplemented with different concentrations of 2,4-Dichlorophenoxyacetic acid (2.2-18 μM) and Kinetin (0.2-1.7 μM). Among the various combinations, 13.5 μM 2,4-D and 1.3 μM Kn resulted in high callus induction frequency (87.5%) with a maximum fresh weight of 0.22 g per segment. The regeneration frequency was 75.5% with multiple shoots within 3 weeks of transfer on MS medium supplemented with 13.3 μM 6-benzylamino purine and 8 μM Naphthaleneacetic acid. The shoots readily rooted on half-strength MS medium without any hormonal supplements. In vitro regenerated plantlets with multiple shoots and roots were transferred to sterile soil and vermiculite mix and maintained in shade house for 30 days. Complete plantlets were then transferred to nursery and acclimatized to the external environment until seed set. RAPD profile reveals monomorphism and thus confirming the genetic stability of the regenerated plants. This method has the potential for both direct as well as indirect method of transformation for the production of genetically modified plants.

    Understanding the popularity dynamics of online application(App) is significant for the online social systems. In this paper, by dividing the Facebook Apps into different groups in terms of their popularities, we empirically investigate the popularity dynamics for different kinds of Facebook Apps. Then, taking into account the influence of cumulative and recent popularities on the user choice, we present a model to regenerate the growth of popularity for different App groups. The experimental results of 917 Facebook Apps show that as the popularities of Facebook Apps increase, the recent popularity plays more important role. Specifically, the recent popularity plays more important role in regenerating the popularity dynamics for more popular Apps, and the cumulative popularity plays more important role for unpopular Apps. We also conduct temporal analysis on the growth characteristic of individual App by comparing the increment at each time with the average of historical records. The results show that the growth of more popular App tends to fluctuate more greatly. Our work may shed some lights for deeply understanding the popularity mechanism for online applications.

    To describe the manner in which migraine and migaineurs are depicted in popular music. Prior studies have elucidated the ways in which the popular perception of neurological disorders is shaped by popular culture, from the inflated expectations of the prognosis of coma patients in television dramas to the association of intractable headaches with demonic possession and death by violence in the cinema. searched popular online music sites for songs with the word "migraine" in their titles. Song lyrics were studied for tone, content, and the light in which they portrayed migraine sufferers. One hundred thirty-four songs met inclusion criteria, representing the work of 126 artists. The majority of the recording artists were male (112 of 126 artists, 89%). One hundred seven of the 134 songs (80%) were recorded since 2000. Of the 79 songs that contained lyrics, 16 (20%) included explicit content; 43 (54%) make reference to hopelessness, despair, or severe pain; and 27 (34%) contained references to killing or death. Only 9 songs (11%) made any reference to successful treatment, resolution, or hope of any sort, the same number that made lyrical references to explosions or bombs. The portrayal of a disease in popular music can reflect the artist's perceptions, anxieties, and prejudices about the disease and its victims. The public, including patients, may accept these portrayals as accurate. Clinicians familiar with the portrayal of headache sufferers in cinema will not be surprised that popular musicians (both migraineurs and non-migraineurs) portray migraines as intractable, violent, and all-consuming. The lack of any balancing view is disheartening, especially in light of the advances in migraine awareness and treatment over the past decade. Perhaps the most surprising finding is that the vast majority of migraine songs are written and performed by men. © 2012 American Headache Society.

  10. READY: a web-based geographical information system for enhanced flood resilience through raising awareness in citizens

    As evidenced by the EU Floods Directive (2007/60/EC), flood management strategies in Europe have undergone a shift in focus in recent years. The goal of flood prevention using structural measures has been replaced by an emphasis on the management of flood risks using non-structural measures. One implication of this is that public authorities alone not only take responsibility for flood management. A broader range of stakeholders, who may personally experience the negative effects of flooding, also take on responsibility for protecting themselves. Therefore, it is vital that information concerning flood risks is conveyed to those who may be affected in order to facilitate the self-protection of citizens. Experience shows that problems persist even where efforts have been made to communicate flood risks. There is a need for the development of new tools that are able to rapidly disseminate flood-risk information to the general public. To be useful these tools must be able to present information relevant to the location of the user. Moreover, the content and design of the tool need to be adjusted to laypeople's needs. Dissemination and communication influence both people's access to and understanding of natural risk information. Such a tool could be a useful aid to effective management of flood risks. To address this gap, a web-based geographical information system (WebGIS) has been developed through the collaborative efforts of a group of scientists, hazard and risk analysts and managers, GIS analysts, system developers and communication designers. This tool, called "READY: Risk, Extreme Events, Adaptation, Defend Yourself", aims to enhance the general public knowledge of flood risk, making citizens more capable of responding appropriately during a flood event. The READY WebGIS has allowed for the visualization and easy querying of a complex hazard and risk database thanks to a high degree of interactivity and easily read maps. In this way, READY has enabled fast

  11. Awareness campaigns: experience in Mexico.

    The current total of AIDS cases in Mexico is 37,000 of which 86% have occurred in men. The major route of transmission is sexual. The campaign to prevent AIDS has fallen into four phases, and has now been extended to other sexually transmitted diseases, including hepatitis B. The first phase (1985-1989) was based around question and answer brochures, which increased awareness but did not remove misconceptions. A mass media campaign addressed these misconceptions and stressed preventive measures. The campaign was halted by opposition to the promotion of condom use on the grounds that it encouraged promiscuity. The second phase (1989-1992) used more conservative messages, but these were too obscure and failed to reach the target audience. A poster campaign using popular lottery characters was widely accepted. In the third phase (1992-1994), a combination of messages was targeted at different populations, including parents and women, and general public sympathy for social support for people with AIDS was encouraged. In the fourth phase (1996-2000), a mass media campaign was aimed at teenagers, with parents and teachers as support groups. The campaign was widened to include HBV infection, and posters and brochures for teenagers were produced. These are distributed as part of a collaboration with non-governmental organizations providing sex education. The private medical sector is being encouraged to provide facilities for hepatitis B vaccination. So far the campaign has only been established in Mexico City, but it is hoped that this will be extended nationwide. Hepatitis B vaccination has been recently included in the National Immunization Programme for infants in the first year of life and it is officially recommended for at-risk populations.

  14. "Popular Culture" and the Academy

    2017-01-01

    Full Text Available The term "popular culture" is mostly used to describe either cultural practices or products that are widespread and available for mass consumption or those practices that belong to the cultural sphere of "ordinary" people. The use of this concept in scholarly research and debate, however, is far from concise and often lacks the analytical clarity needed for sound and convincing knowledge production. Lacking a precise and viable definition for this concept, this essay argues for abolishing it in favor of the concept of "culture", which in itself can be operationalized so as to accommodate all forms and practices that can be perceived as cultural. The central argument consists of a critique of the inherent classifications of culture through respective adjectives that inevitably lead to normative assumptions and presuppose specific research questions or methods.

    The Extreme ultraviolet Imaging Telescope on board SOHO, designed and built by Principal Investigator Jean-Pierre Delaboudiniere and his French/Belgan/US team, has produced numerous scientific breakthroughs, and has become both the standard coronal finder telescope and the determinant of whether halo coronal mass ejections are earthward-directed. Due to the dramatic nature of the images produced by EIT over the last nearly ten years, those images have been adopted worldwide in a manner no one could have foreseen before the launch of SOHO. I examine a small sample of the many scientific, commercial, and cultural uses of EIT imagery from the last decade in order to demonstrate how well-visualized, scientific imagery can first penetrate and then become an accepted part of the popular imagination.

    Previous studies of weather-inspired classical music showed that all forms of music (as well as visual arts and literature) reflect the significance of the environment in society. Here we quantify the extent to which weather has inspired popular musicians, and how weather is represented in English-language pop music. Our work is in press at Weather. Over 750 songs have been identified which were found to refer to meteorological phenomena, mainly in their lyrics, but also in the title of the song, name of the band or songwriter and occasionally in the song's music or sound effects. Over one third of the songs analysed referred to either sun or rain, out of a possible 20 weather categories. It was found that artists use weather to describe emotion, for example, to mirror the changes in a relationship. In this context, rain was broadly seen negatively, and might be used to signify the end of a relationship. Rain could also be perceived in a positive way, such as in songs from more agricultural communities. Wind was the next most common weather phenomenon, but did not represent emotions as much as sun or rain. However, it was the most frequently represented weather type in the music itself, such as in instrumental effects, or non-verbally in choruses. From the limited evidence available, we found that artists were often inspired by a single weather event in writing lyrics, whereas the outcomes were less clearly identifiable from longer periods of good or bad weather. Some artists were influenced more by their environment than others, but they were often inspired to write many songs about their surroundings as part of every-day life, rather than weather in particular. Popular singers and songwriters can therefore emotionally connect their listeners to the environment; this could be exploited to communicate environmental science to a broad audience.

    2000-01-01

    In response to the SIECUS Report entitled "Adolescent Sexuality and Popular Culture", Susan Bankowski of the Campaign for Our Children, Inc. explains why knowledge about popular culture is so important in work dealing with young people. It is noted that blame has often been placed on pop culture as contributing to American youth's early initiation into sexual activity. Various studies and groups of people cite the explicit display of sex in media as a major reason for such behavior of teens. However, in Europe, where teen birthrates are much lower and contraceptive use is higher than in the US, sex and sexuality are an accepted part of media expression. In view of this, Bankowski states that there is a need for sexuality educators to embrace the media that influence the teens with whom they work. Drawing on her own experience, Bankowski further explains that educators need to be aware of trends when selecting educational materials.

    In Malaysia, homosexuality is illegal; little is known about access to HIV prevention services among Malaysian men who have sex with men (MSM). We analysed PT Foundation outreach data to describe the profiles among MSM who accessed PT Foundation services and to examine factors associated with being aware of PT Foundation and having visited the organization. A survey was administered during weekly outreach throughout Kuala Lumpur from March-December 2012. Pearson's Chi square tests were used to compare demographic and behavioural characteristics of participants who were and were not aware of the PT Foundation. Binary logistic regression was used to identify correlates of MSM visiting the PT Foundation among those who had heard of the organization. Of 614 MSM, this study found significantly higher awareness of the PT Foundation among MSM who perceived they had "good" HIV knowledge (p = .026) and participants who reported always using condoms (p = .009). MSM who reported being paid for sex were 2.81 times as likely to visit the PT Foundation compared to men who did not. A subgroup of MSM known to be at high risk for HIV infection is accessing prevention services. Future studies should uncover motivations and barriers of accessing these services among MSM in Malaysia. © The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

The examples are drawn from my recently published catalog of 133 such pieces, including both classical and popular genres of music. We discuss operas based on the life and work of astronomers, six songs based on a reasonable understanding of the properties of black holes, constellation pieces written by composers from around the world who are or were active amateur astronomers, the song that compares walking on the Moon to being in love, the little-known rock song that became a reference in the Astrophysical Journal, pieces that base the patterns of the music on the rhythms of astronomical phenomena, and a number of others.

    To boost the productivity of groundnut, farmers need to have an access to improved seeds of the right variety, at the right time, at the right place, at an affordable price. The awareness and benefits of the improved varieties and quality seeds of groundnut was carried out by carefully planned co-ordinated educational systems such as field trials, demonstrations, field days, training farmers, interface meetings through the well established network of the University and mass media promotional tools. The BARC-UASD collaboration led to the popularization of BARC groundnut varieties like TAG-24, TG-26, TPG-41 and TDG-39 among the farming community of north Karnataka. (author)

    Control room modernization is critical to extending the life of the 99 operating commercial nuclear power plants (NPP) within the United States. However, due to the lack of evidence demonstrating the efficiency and effectiveness of recent candidate technologies, current NPP control rooms operate without the benefit of various newer technologies now available. As nuclear power plants begin to extend their licenses to continue operating for another 20 years, there is increased interest in modernizing the control room and supplementing the existing control boards with advanced technologies. As part of a series of studies investigating the benefits of advanced control room technologies, the researchers conducted an experimental study to observe the effect of Task-Based Overview Displays (TODs) on operator workload and situation awareness (SA) while completing typical operating scenarios. Researchers employed the Situation Awareness Rating Technique (SART) and the NASA Task Load Index (TLX) as construct measures.

Few respondents (9% currently followed a plant-based diet, but 66% indicated willingness to follow one for 3 weeks. Family eating preferences and meal planning skills were common barriers to diet change. 72% of healthcare providers reported knowledge of plant-based diets for diabetes management but low levels of practice. Conclusions and Implications. Patient awareness of the benefits of a plant-based diet for the management of diabetes remains suboptimal and may be influenced by perception of diabetes educators and clinicians. Given the reported willingness to try (but low current use of plant-based diets, educational interventions targeting patient and provider level knowledge are warranted.

    Popularity of social marketing messages indicates the effectiveness of the corresponding marketing strategies. This research aims to discover the characteristics of social marketing messages that contribute to different level of popularity. Using messages posted by a sample of restaurants on Facebook as a case study, we measured the message popularity by the number of "likes" voted by fans, and examined the relationship between the message popularity and two properties of the messages: (1) content, and (2) media type. Combining a number of text mining and statistics methods, we have discovered some interesting patterns correlated to "more popular" and "less popular" social marketing messages. This work lays foundation for building computational models to predict the popularity of social marketing messages in the future.

    Online popularity has a major impact on videos, music, news and other contexts in online systems. Characterizing online popularity dynamics is nature to explain the observed properties in terms of the already acquired popularity of each individual. In this paper, we provide a quantitative, large scale, temporal analysis of the popularity dynamics in two online video-provided websites, namely MovieLens and Netflix. The two collected data sets contain over 100 million records and even span a decade. We characterize that the popularity dynamics of online videos evolve over time, and find that the dynamics of the online video popularity can be characterized by the burst behaviors, typically occurring in the early life span of a video, and later restricting to the classic preferential popularity increase mechanism.

    Building upon the advancement of technology during the Second World War and the important scientific discoveries which have been made about the structure and components of the universe, scientists, especially in radio astronomy and physics, began seriously addressing the possibility of extraterrestrial intelligence in the 1960s. The Search for Extraterrestrial Intelligence (SETI) quickly became one of the most controversial scientific issues in the post Second World War period. The controversy played out, not only in scientific and technical journals, but in newspapers and in popular literature. Proponents for SETI, including Frank Drake, Carl Sagan, and Philip Morrison, actively used a strategy of engagement with the public by using popular media to lobby for exposure and funding. This paper will examine the use of popular media by scientists interested in SETI to popularize and heighten public awareness and also to examine the effects of popularization on SETI's early development.

  14. Perception without awareness: perspectives from cognitive psychology.

    Merikle, P M; Smilek, D; Eastwood, J D

    2001-04-01

    Four basic approaches that have been used to demonstrate perception without awareness are described. Each approach reflects one of two types of experimental logic and one of two possible methods for controlling awareness. The experimental logic has been either to demonstrate a dissociation between a measure of perception with awareness and a measure that is sensitive to perception without awareness or to demonstrate a qualitative difference between the consequences of perception with and without awareness. Awareness has been controlled either by manipulating the stimulus conditions or by instructing observers on how to distribute their attention. The experimental findings based on all four approaches lead to the same conclusion; namely, stimuli are perceived even when observers are unaware of the stimuli. This conclusion is supported by results of studies in which awareness has been assessed with either objective measures of forced-choice discriminations or measures based on verbalizations of subjective conscious experiences. Given this solid empirical support for the concept of perception without awareness, a direction for future research studies is to assess the functions of information perceived without awareness in determining what is perceived with awareness. The available evidence suggests that information perceived without awareness both biases what stimuli are perceived with awareness and influences how stimuli perceived with awareness are consciously experienced.

How to evaluate the popularities of microblogging users is an important research field, which can be applied to commercial advertising, user behavior analysis and information dissemination, and so forth. Previous studies on the evaluation methods cannot effectively solve and accurately evaluate the popularities of the microbloggers. In this paper, we proposed an electromagnetic field theory based model to analyze the popularities of microbloggers. The concept of the source in microblogging field is first put forward, which is based on the concept of source in the electromagnetic field; then, one’s microblogging flux is calculated according to his/her behaviors (send or receive feedbacks on the microblogging platform; finally, we used three methods to calculate one’s microblogging flux density, which can represent one’s popularity on the microblogging platform. In the experimental work, we evaluated our model using real microblogging data and selected the best one from the three popularity measure methods. We also compared our model with the classic PageRank algorithm; and the results show that our model is more effective and accurate to evaluate the popularities of the microbloggers.

    Since the large North Eastern power system blackout on August 14, 2003, U.S. electric utilities have spent lot of effort on preventing power system cascading outages. Two of the main causes of the August 14, 2003 blackout were inadequate situational awareness and inadequate operator training In addition to the enhancements of the infrastructure of the interconnected power systems, more research and development of advanced power system applications are required for improving the wide-area security monitoring, operation and planning in order to prevent large- scale cascading outages of interconnected power systems. It is critically important for improving the wide-area situation awareness of the operators or operational engineers and regional reliability coordinators of large interconnected systems. With the installation of large number of phasor measurement units (PMU) and the related communication infrastructure, it will be possible to improve the operators’ situation awareness and to quickly identify the sequence of events during a large system disturbance for the post-event analysis using the real-time or historical synchrophasor data. The purpose of this project was to develop and demonstrate a novel synchrophasor-based comprehensive situational awareness system for control centers of power transmission systems. The developed system named WASA (Wide Area Situation Awareness) is intended to improve situational awareness at control centers of the power system operators and regional reliability coordinators. It consists of following main software modules: • Wide-area visualizations of real-time frequency, voltage, and phase angle measurements and their contour displays for security monitoring. • Online detection and location of a major event (location, time, size, and type, such as generator or line outage). • Near-real-time event replay (in seconds) after a major event occurs. • Early warning of potential wide-area stability problems.

    Healthcare systems are organized following one of two basic models: social security systems, which link access to health services to labor status, and national health systems, which grant access to health as a citizen's right. Mexico adopted, since the institutionalization of social security and healthcare services in 1943, a mixed system. Social security institutions covered the salaried workers and public assistance was granted to the remaining of the population. At the beginning of the XXI century the Mexican health system entered a crisis as the conditions to expand health coverage through social security were not met and public assistance services were insufficient. In order to address these developments, the Healthcare Social Protection System was founded (2004) as a mechanism to effectively guarantee every person's right to health as established after the constitutional amendment of article fourth in 1983. Seguro Popular is the mechanism that through federal and states' contributions seeks to financially protect the population without access to social security's health services, and thus prevent impoverishment due to out of pocket and catastrophic health expenditures.

    Full Text Available Context-aware smart things are capable of computational behaviour based on sensing the physical world, inferring context from the sensed data, and acting on the sensed context. A collection of such things can form what we call a thing-ensemble, when they have the ability to communicate with one another (over a short range network such as Bluetooth, or the Internet, i.e. the Internet of Things (IoT concept, sense each other, and when each of them might play certain roles with respect to each other. Each smart thing in a thing-ensemble might have its own context-aware behaviours which when integrated with other smart things yield behaviours that are not straightforward to reason with. We present Sigma, a language of operators, inspired from modular logic programming, for specifying and reasoning with combined behaviours among smart things in a thing-ensemble. We show numerous examples of the use of Sigma for describing a range of behaviours over a diverse range of thing-ensembles, from sensor networks to smart digital frames, demonstrating the versatility of our approach. We contend that our operator approach abstracts away low-level communication and protocol details, and allows systems of context-aware things to be designed and built in a compositional and incremental manner.

    The leakage of confidential information is one of important issues in the network security area. Elastic Optical Networks (EON) as a promising technology in the optical transport network is under threat from eavesdropping attacks. It is a great demand to support confidential information service (CIS) and design efficient security strategy against the eavesdropping attacks. In this paper, we propose a solution to cope with the eavesdropping attacks in routing and spectrum allocation. Firstly, we introduce probability theory to describe eavesdropping issue and achieve awareness of eavesdropping attacks. Then we propose an eavesdropping-aware routing and spectrum allocation (ES-RSA) algorithm to guarantee information security. For further improving security and network performance, we employ multi-flow virtual concatenation (MFVC) and propose an eavesdropping-aware MFVC-based secure routing and spectrum allocation (MES-RSA) algorithm. The presented simulation results show that the proposed two RSA algorithms can both achieve greater security against the eavesdropping attacks and MES-RSA can also improve the network performance efficiently.

    Full Text Available Abstract Background The present study aimed to provide information on awareness of the attributable fraction of cancer causes among the Japanese general population. Methods A nationwide representative sample of 2,000 Japanese aged 20 or older was asked about their perception and level of concern about various environmental and genetic risk factors in relation to cancer prevention, as a part of an Omnibus Survey. Interviews were conducted with 1,355 subjects (609 men and 746 women. Results Among 12 risk factor candidates, the attributable fraction of cancer-causing viral and bacterial infection was considered highest (51%, followed by that of tobacco smoking (43%, stress (39%, and endocrine-disrupting chemicals (37%. On the other hand, the attributable fractions of cancer by charred fish and meat (21% and alcohol drinking (22% were considered low compared with other risk factor candidates. For most risk factors, attributable fraction responses were higher in women than in men. As a whole, the subjects tended to respond with higher values than those estimated by epidemiologic evidence in the West. The attributable fraction of cancer speculated to be genetically determined was 32%, while 36% of cancer was considered preventable by improving lifestyle. Conclusion Our results suggest that awareness of the attributable fraction of cancer causes in the Japanese general population tends to be dominated by cancer-causing infection, occupational exposure, air pollution and food additives rather than major lifestyle factors such as diet.

    Full Text Available Approaching from the perspective of sociological studies of natural disasters, the article probes the issue of the construction of popular housing and of the community's relations with its constructed environment. Based on an empirical study of landslides in a hilly area on Recife's north side, it seeks to ascertain how much is known about practices that can minimize the effects of the disaster felt by the community. Information derived from questionnaires and interviews is used to reconstruct both the population's strategies in the face of landslides as well as their views on the place where they live. This information likewise serves as a basis in identifying the community's vulnerability and its capacity to deal with its surrounding environment.

  4. Science and Facebook: The same popularity law!

    Full Text Available The distribution of scientific citations for publications selected with different rules (author, topic, institution, country, journal, etc… collapse on a single curve if one plots the citations relative to their mean value. We find that the distribution of "shares" for the Facebook posts rescale in the same manner to the very same curve with scientific citations. This finding suggests that citations are subjected to the same growth mechanism with Facebook popularity measures, being influenced by a statistically similar social environment and selection mechanism. In a simple master-equation approach the exponential growth of the number of publications and a preferential selection mechanism leads to a Tsallis-Pareto distribution offering an excellent description for the observed statistics. Based on our model and on the data derived from PubMed we predict that according to the present trend the average citations per scientific publications exponentially relaxes to about 4.

    Full Text Available The obvious thing to say about popular science publishing in the last twenty years is that there has been a lot of it! That is important in itself. But it also means it is hazardous to offer general comment. The British journalist and commentator Bryan Appleyard recently wrote in the Sunday Times that the “hard stuff” in science was no longer attracting so many readers. Books answering many small questions about the world, or evoking a sense of wonder, do better - he reckons - than those which offer large certainties based on a scientific, or scientistic view of the world. That type, Appleyard claims, dominated the field for years after Steven Hawking’s A Brief History of Time, with its promise of a theory of everything.

    Performance data and metadata of the computing operations at the CMS experiment are collected through a distributed monitoring infrastructure, currently relying on a traditional Oracle database system. This paper shows how to harness Big Data architectures in order to improve the throughput and the efficiency of such monitoring. A large set of operational data - user activities, job submissions, resources, file transfers, site efficiencies, software releases, network traffic, machine logs - is being injected into a readily available Hadoop cluster, via several data streamers. The collected metadata is further organized running fast arbitrary queries; this offers the ability to test several Map&Reduce-based frameworks and measure the system speed-up when compared to the original database infrastructure. By leveraging a quality Hadoop data store and enabling an analytics framework on top, it is possible to design a mining platform to predict dataset popularity and discover patterns and correlations.

    AMP! (Arts-based, Multiple component, Peer-education) is an HIV intervention developed for high school adolescents. AMP! uses interactive theater-based scenarios developed by trained college undergraduates to deliver messages addressing HIV/STI prevention strategies, healthy relationships, and stigma reduction towards people living with HIV/AIDS. We used a pre-test/post-test, control group study design to simultaneously assess intervention effect on ninth grade students in an urban county in California (N = 159) and a suburban county in North Carolina (N = 317). In each location, the control group received standard health education curricula delivered by teachers; the intervention group received AMP! in addition to standard health education curricula. Structural equation modeling was used to determine intervention effects. The post-test sample was 46 % male, 90 % self-identified as heterosexual, 32 % reported receiving free or reduced lunch, and 49 % White. Structural models indicated that participation in AMP! predicted higher scores on HIV knowledge (p = 0.05), HIV awareness (p = 0.01), and HIV attitudes (p = 0.05) at the post-test. Latent means comparison analyses revealed post-test scores were significantly higher than pre-test scores on HIV knowledge (p = 0.001), HIV awareness (p = 0.001), and HIV attitudes (p = 0.001). Further analyses indicated that scores rose for both groups, but the post-test scores of intervention participants were significantly higher than controls (HIV knowledge (p = 0.01), HIV awareness (p = 0.01), and HIV attitudes (p = 0.05)). Thus, AMP!'s theater-based approach shows promise for addressing multiple adolescent risk factors and attitudes concerning HIV in school settings.

    Full Text Available Phishing has grown significantly in volume over the time, becoming the most usual web threat today. The present economic crisis is an added argument for the great increase in number of attempts to cheat internet users, both businesses and private ones. The present research is aimed at helping the IT environment get a more precise view over the phishing attacks in Romania; in order to achieve this goal we have designed an application able to retrieve and interpret phishing related data from five other trusted web sources and compile them into a meaningful and more targeted report. As a conclusion, besides making available regular reports, we underline the need for a higher degree of awareness related to this issue.

    This article theorizes civil society groups' attempts to popularize opposition to genetic modification in New Zealand as deliberative interventions that seek to open up public participation in science-society governance. In this case, the popularization strategies were designed to intensify concerns about social justice and democratic incursions, mobilize dissent and offer meaningful mechanisms for navigating and participating in public protest. Such civic popularization efforts, we argue, are more likely to succeed when popularity and politicization strategies are judiciously integrated to escalate controversy, re-negotiate power relations and provoke agency and action. © The Author(s) 2014.

    Previous studies have demonstrated that household contacts of cholera patients are highly susceptible to cholera infections for a 7-day period after the presentation of the index patient in the hospital. However, there is no standard of care to prevent cholera transmission in this high-risk population. Furthermore, there is limited information available on awareness of cholera transmission and prevention among cholera patients and their household contacts. To initiate a standard of care for this high-risk population, we developed the Cholera-Hospital-Based-Intervention-for-7-Days (CHoBI7), which delivers a handwashing with soap and water treatment intervention to household contacts during the time they spend with the admitted cholera patient in the hospital and reinforces these messages through home visits. To test CHoBI7, we conducted a randomized controlled trial among 302 intervention cholera patient household members and 302 control cholera patient household members in Dhaka, Bangladesh. In this study, we evaluated the effectiveness of the CHoBI7 intervention in increasing awareness of cholera transmission and prevention, and the key times for handwashing with soap. We observed a significant increase in cholera knowledge score in the intervention arm compared with the control arm at both the 1-week follow-up {score coefficient = 2.34 (95% confidence interval [CI] = 1.96, 2.71)} and 6 to 12-month follow-up period (score coefficient = 1.59 [95% CI = 1.05, 2.13]). This 1-week hospital- and home-based intervention led to a significant increase in knowledge of cholera transmission and prevention which was sustained 6 to 12 months post-intervention. These findings suggest that the CHoBI7 intervention presents a promising approach to increase cholera awareness among this high-risk population. © The American Society of Tropical Medicine and Hygiene.

    Accidental awareness during general anaesthesia (AAGA) is when a patient unintentionally becomes conscious during a procedure performed with general anaesthesia and subsequently has explicit recall of this event. Incidence estimates for AAGA vary, with the most common estimate being one to two cases per 1000 general anaesthetics. Evidence linking nitrous oxide use and an increased risk of AAGA has come from observational studies data but the literature is contradictory, with some studies finding a protective effect of nitrous oxide. To assess the effect of general anaesthesia including nitrous oxide on the risk of AAGA in patients aged five years and over. We searched the following databases: Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE and trial registers ((www.clinicaltrials.gov), the WHO International Clinical Trials Registry Platform (www.who.int/ictrp/network/en/) and Current Controlled Trials (www.isrctn.com/)) for eligible studies on December 9 2015. In addition, we conducted forward and backward citation searching using key identified papers. We considered all randomized controlled trials (RCTs), including quasi-randomized studies and cluster-randomized studies, of participants aged five years or older receiving general anaesthesia for any type of surgery.We included trials in which participants receiving general anaesthesia that included nitrous oxide for maintenance at a concentration of at least 30% were compared with participants receiving no nitrous oxide during general anaesthesia. The intervention group must have received nitrous oxide in conjunction with an additional anaesthetic. We excluded studies where the depth of anaesthesia differed between the study arms. For inclusion in the review, studies needed to state in their methods that they planned to assess AAGA. We defined this as when a patient becomes conscious during a procedure performed with general anaesthesia and subsequently has explicit recall of this event

    A wide range of electronic cigarettes (e-cigarettes) are now on the market. We studied e-cigarette awareness and use, determinants and sources of e-cigarettes, the e-liquids used in them and exposure to e-cigarette advertisements among adolescents in Finland. Among smokers, we studied the association of e-cigarette use and interest in smoking cessation. Data were obtained from a national survey of 12-18-year-old Finnish adolescents in 2013 (N=3535, response rate 38%). Descriptive statistics and logistic regression analysis were used. Of the respondents, 85.3% knew what e-cigarettes were; 17.4% had tried them. E-liquids with nicotine were used most often (65.7%); also those who had never tried conventional cigarettes had used them. Of e-cigarette ever users, 8.3% had never tried smoking. Parents' high level of education, being in employment, and intact family protected against children's e-cigarette use. In the final model, daily smoking (OR 41.35; 95% CI 25.2 to 67.8), snus use (2.96; 2.4-4.0), waterpipe use (2.21; 1.6-3.0), children's vocational education (2.06; 1.4-3.1) and poor school performance (1.92; 1.4-3.0) were associated with e-cigarette experimentation. Those smokers with most experience of e-cigarettes were least likely to consider smoking cessation. Awareness and experimentation with e-cigarettes are high among adolescents, especially in older age groups and boys. Nicotine e-liquids are easy to acquire for youth. Having similar risk factors, e-cigarette use seems to follow the model of conventional smoking initiation. Among adolescent smokers, use of e-cigarettes does not clearly relate to interest in smoking cessation. Preventive policies are needed to protect the youth.

    In real world, human activities often exhibit preferential selection mechanism based on the popularity of individuals. However, this mechanism is seldom taken into account by previous studies about spreading dynamics on networks. Thus in this work, an information spreading model is proposed by considering the preferential selection based on individuals' current popularity, which is defined as the number of individuals' cumulative contacts with informed neighbors. A mean-field theory is developed to analyze the spreading model. Through systematically studying the information spreading dynamics on uncorrelated configuration networks as well as real-world networks, we find that the popularity preference has great impacts on the information spreading. On the one hand, the information spreading is facilitated, i.e., a larger final prevalence of information and a smaller outbreak threshold, if nodes with low popularity are preferentially selected. In this situation, the effective contacts between informed nodes and susceptible nodes are increased, and nodes almost have uniform probabilities of obtaining the information. On the other hand, if nodes with high popularity are preferentially selected, the final prevalence of information is reduced, the outbreak threshold is increased, and even the information cannot outbreak. In addition, the heterogeneity of the degree distribution and the structure of real-world networks do not qualitatively affect the results. Our research can provide some theoretical supports for the promotion of spreading such as information, health related behaviors, and new products, etc.

    Full Text Available Large variations in network Quality of Service (QoS such as bandwidth, latency, jitter, and reliability may occur during media transfer over vehicular ad hoc networks (VANET. Usage of VANET over mobile and wireless computing applications experience “bursty” QoS behavior during the execution over distributed network scenarios. Applications such as streaming media services need to adapt their functionalities to any change in network status. Moreover, an enhanced software platform is necessary to provide adaptive network management services to upper software components. HOSA, a handoff service broker based architecture for QoS adaptation over VANET supports in providing awareness. HOSA is structured as a middleware platform both to provide QoS awareness to streaming applications as well to manage dynamic ad hoc network resources with support over handoff in an adaptive fashion. HOSA is well analyzed over routing schemes such as TIBSCRPH, SIP and ABSRP where performance of HOSA was measured using throughput, traffic intensity and end to end delay. HOSA has been analyzed using JXTA development toolkit over C++ implemented classes to demonstrate its performance over varying node mobility established using vehicular mobility based conference application.

    Mindfulness-based interventions are reported to be highly acceptable and have positive effects on youth, yet most are clinic- or school-based aimed at emotional regulation or academic performance. To provide flexible program delivery, we developed and tested a standalone mindfulness-based app aimed at improving weight-related behaviors (eg, diet, physical activity, sleep) in adolescents. Our objective was to assess the feasibility, acceptability, and utility of a mindfulness-based mobile app. In a single-arm pilot study, 15 adolescents (14-18 years) were prompted to access the app once a day, every day for 6 weeks. Outcomes were measured by in-app and poststudy surveys, and descriptive statistical analyses were performed. Time within a mindfulness state was self-reported during weekly timed practices. The app was rated highly for content and encouraging the practice of activities to promote mindfulness states. Teens reported increased awareness of eating behaviors and high adherence, particularly during physically active practices. Average self-reported time spent in a mindfulness state increased 2.5 times by week 6 (78 [SD 17] seconds) compared to week 1 (31 [SD 21] seconds). The high acceptability and utility ratings of the app, increases in reported time in mindfulness states, and high frequency of participation, including mindful eating and physical activity, suggest the mindfulness-based mobile app has the potential to improve awareness of weight-related behaviors. ©Tami Turner, Melanie Hingle.

    Nonindustrial private forest owners (NIPFs) in Finland are important stakeholders of forest management and roundwood supply decisions. Their role will also be significant to supply energy wood to meet Finland's target for renewable energy in the future. The main objectives of this study were to explore the opinions and awareness of the Finnish NIPFs related to the energy wood market and forest-based bioenergy certification issues in Finland and their relevance for future bioenergy policies. A questionnaire-based survey was conducted among NIPFs in Finnish Karelia (N = 79). NIPFs considered price as the main deciding factor in harvesting and selling of energy wood. The present low price of energy wood compared to pulpwood did not motivate them to increase harvesting and selling of energy wood. The NIPFs appeared to be unaware of the forest-based bioenergy certification. However, they expected that such certification schemes would be easy to follow, develop energy wood market, and promote environmentally sound forest management practices in Finland. Private forest owners' associations and personal information letters emerged as the most favored means to disseminate information on forest-based bioenergy certification to the Finnish NIPFs. The study explored the opinions and awareness of the Finnish NIPFs related to energy wood market and forest based bioenergy certification from Finnish Karelia. The conclusions derived from the study might be highly policy-relevant concerning the development of energy wood market and related certification schemes. Future studies should include larger sample size for increasing the representativeness of the findings. (orig.)

    Canine rabies represents a major - but preventable - public health threat in Chad. In preparation for a nation-wide canine parenteral mass vaccination campaign we conducted a community-based, cross-sectional multi-stage cluster survey in 40 villages in two southern and two northern regions of Chad. Our objective was to investigate rabies awareness and dog-ownership among the rural population. Almost half of the households (45%) owned dogs, with an overall dog:human ratio of 1:7.8. Southern households owned almost two thirds (701/918) of all dogs and the number of dogs per household was twice as high compared to the north (2.7 vs. 1.3, respectively). This translates into a dog:human ratio of 1:5.2 in the south and 1:16.4 in the north. Only 76% of the respondents had heard of rabies. Respondents who (1) were male, (2)>19 years, (3) had primary education or higher and (4) were of Muslim faith were more likely to have heard of rabies (prabies knowledge was positively associated with (1) southern residence, (2) any kind of education and (3) Christian or "other" religions. In contrast to rabies awareness, high level of knowledge was negatively associated with increasing age. 11% of respondents reported that at least one family member had been bitten by a dog in the past year and half of these bite victims were children. 31% of respondents knew someone who had died of rabies and twice as many (58%) reported having encountered a rabid animal. Most of the respondents could identify classical rabies symptoms (58-94%), however they lacked knowledge about rabies prevention and appropriate wound management. Only 2 out of 963 (0.5%) reported to have vaccinated their dog. A major proportion of our study population is at great risk of rabies (likely higher than 7 rabies death per million per year) due to lack of awareness of the disease, inappropriate post-bite treatment and insufficient knowledge about preventive measures. This reflects the urgent need for advocacy programs to

  16. Gender messages in contemporary popular Malay songs

    Full Text Available Gender has been an important area of research in the field of popular music studies. Numerous scholars have found that contemporary popular music functions as a locus of diverse constructions and expressions of gender. While most studies focus on content analyses of popular music, there is still a need for more research on audience’s perception of popular music’s messages. This study examined adult Malay listeners’ perceptions of gender messages in contemporary Malay songs. A total of 16 contemporary Malay songs were analysed using Fairclough’s (1992 method of text analysis. The content of the songs that conveyed messages about gender were the basis for analysis. The results showed that the messages revolve mainly around socially constructed gender roles and expectations in romantic relationships. Gender stereotypes are also used in the songs to reinforce men’s and women’s roles in romantic relationships. The results also showed that, while listeners acknowledge the songs’ messages about gender, their own perceptions of gender and what it means to be a gendered being in today’s world are neither represented nor discussed fully in the songs analysed. It is hoped the findings from this, particularly the mismatch between projected and perceived notions of gender, contribute to the field of popular Malay music studies in particular, and popular music studies in general where gender messages in popular songs and their influence on listeners’ perceptions of their own gender is concerned.

    Mercury, one of the most toxic heavy metals, is ubiquitous in environment. The adverse health impact of mercury on living organisms is well known. The health care facilities are one of the important sources of mercury release into the atmosphere as mercury items are extensively used in hospitals. To assess the awareness about mercury toxicity and the knowledge of proper handling and disposal of mercury-containing items in health care set-up, a questionnaire-based survey was carried out amongst doctors (n = 835), nurses (n = 610) and technicians (n = 393) in government hospitals, corporate hospitals and primary health care centres in the Indian states of Delhi, Uttar Pradesh and Haryana. The study was conducted using a tool-containing pretested structured multiple-choice questionnaire. Analysis of the results using STATA 11.1 software highlighted that overall awareness was more in corporate sector. However, percentage range of knowledge of respondents irrespective of health care sector was only between 20 and 40%. Despite the commitment of various hospitals to be mercury free, mercury containing-thermometer/sphygmomanometer are still preferred by health professionals. The likely reasons are availability, affordability, accuracy and convenience in use. There is an urgent need for source reduction, recycling and waste minimization. Emphasis must be laid on mercury alternative products, education and training of health personnel and public at large, about correct handling and proper clean up of spills. © The Author(s) 2013.

    The aim of this study was to assess the knowledge about the risk of infertility in cancer patients after treatment, and the options for fertility preservation based on a survey carried out during the 2013 Pink October campaign. This survey was carried out during the 2013 Pink October event in the most important public park of São Paulo, Brazil. Approximately 900 people expressed interest in learning about breast cancer prevention and fertility preservation by participating in workshops, and 242 people filled out a questionnaire. Most of the respondents (78.5%) were women, and one-fourth (25%) had at least one relative with gynecological cancer. Among women over 40 years of age, 86.3% had been screened for breast cancer at some point. However, few participants (34.0%) were aware that cancer treatment can lead to infertility or had heard about fertility preservation options (22.0%). Having a relative with cancer did not influence their knowledge about fertility preservation (22.4% versus 21.3%; p=0.864). However, a higher educational level was significantly associated with more knowledge about the effects of cancer on fertility and options for fertility preservation. The majority of participants did not have knowledge about the impact of oncologic treatment on fertility and did not know that there are options to preserve fertility in cancer patients. Awareness of infertility risk factors is an essential first step to safeguard future fertility, and therefore, more educational initiatives are needed to spread knowledge about oncofertility.

    There have been analyzed reasons of the loss of technical education’s popularity. Also, the analysis of known educational and production methods, oriented at the innovative model of development of society, was performed. It is stated that the acquisition of 21st century’s skills as a result of competition of technical education are natural for the DIY ideology, which was realized in the institutions like Fab Lab. The new educational strategy, based on project-based learning, is proposed to be implemented as a special laboratory with equipment, which would be a center of innovative development for students at the Technical University. Moreover, the list of projects planned for implementation, that includes not only projects, specific to a particular university, but also projects, demanded by society as a whole, is specified. It is worth to implement trendy projects in the laboratory, such as toy-like, ecological projects; projects of the energy dependence decrease or the energy efficiency increase, modern digital or innovative projects etc. The student should gain knowledge, skills and, possibly, equipment that are available for immediate usage on the labor market or for the realization of his own projects or the community’s projects in everyday life after the realization of the particular project at the laboratory

    The Information Systems Office (ISO) at DARPA develops, applies, integrates, and transitions information technology and systems to enable domination of the battlespace. To that end, ISO is engaged in three thrusts: comprehensive battlespace awareness; intelligent and timely force management and battle execution; and, realistic and affordable simulation for training, mission rehearsal, and course of action evaluation. In each thrust, ISO concentrates on enduring and future threats and solutions. The development approach involves creating the next generation of infrastructure, technology, and applications to build, sustain, and maintain a tightly-coupled system of systems. ISO information systems drive evolving concepts and doctrine for implementing a new warfare paradigm in which knowledge, not mass and fire power, is key to battlespace dominance across the ever-expanding spectrum of conflict. DARPA views its Battlespace Awareness Program as the catalyst for accelerating the implementation of a continually-evolving system of information technology that will enable the information-based warfare paradigm described above. The roadmap being followed by DARPA is to design, develop and transition a pilot infrastructure of information systems that can be used to enable emerging new operational concepts and guide future system developments and acquisitions. This infrastructure requires integrated system applications and a common information support environment.

    Purpose Although safe Internet use is an emerging public health issue, there is a scarcity of published work describing relevant school-based interventions. The objective of this study was to explore the impact of a health professional-led, school-based intervention in raising awareness on cyber-safety in adolescents, Therefore, the aim of this study was to investigate adolescents' evaluation of this school-based intervention, 6 months after its implementation, as well as the impact of adolescents' school class and gender on their evaluation. Methods A student sample was selected using a multistage stratified random sampling technique, according to the location and school grade level (middle, high school). The students - aged from 12 to 18 years old experienced an interactive presentation in their classrooms on the amount of time spent online, the use of social networks and the available support services. An evaluation tool was completed anonymously and voluntarily 6 months after the intervention. Results Four hundred and sixty-two students (response rate 90.7%, 246 middle, 216 high school) completed the evaluation tool. Younger students, especially the ones in the first year of middle school, scored significantly higher in all six parameters used in the evaluation of this intervention compared with all the older participants: (a) they had kept the presented information on Safeline and Saferinternet websites and the helpline Ypostirizo (70.2% vs. 33.7%, p impact of the intervention on the youngest students underlines the need for raising awareness on cyber-safety and support services, earlier in the students' life.

Yet other work in this research stream and in the sociology of classification argues for the continued prevalence of genres as a meaningful tool through which creators, critics and consumers focus their attention in the topology of available works. Building from work in the study of categories and categorization we examine how boundary strength and internal differentiation structure the genre pairings of some 3 million musicians and groups. Using a range of network-based and statistical techniques, we uncover three musical "complexes," which are collectively constituted by 16 smaller genre communities. Our analysis shows that the musical universe is not monolithically organized but rather composed of multiple worlds that are differently structured-i.e., uncentered, single-centered, and multi-centered.

    CAN/SDI is Canada's national Selective Dissemination of Information Service offering a choice of nine data bases to its scientific and technical community. The system is based on central processing at the National Science Library combined with the utilization of decentralized expertise and resources for profile formulation and user education. Its greatest strength lies in its wide interdisciplinary quality. The major advantage of centralized processing of many data bases is that Canadians need learn only one method of profile formulation to access many files. A breakdown of services used confirms that a single tape service does not cover all the information requirements of most users. On the average each profile accesses approximately 1.5 data bases. Constant subscriber growth and a low cancellation rate indicate that CAN/SDI is and will continue to be an important element in Canada's information system.

    This review gives the mode of action, efficacy, causes of failure, advantages, drawbacks, and geographical areas of wide use of abstinence, withdrawal, postcoital douche, lactation, condom, cervical cap, spermicides, and rhythm. The effectiveness of these methods ranges from 15-20 failures/100 woman-years for withdrawal, 30-60% for douche, 8-17% for lactation, 10-20% for condom, 8% theoretically for cap, 15-25% for spermicides and 3-15% for C-film, and 7-40% for rhythm. Coitus interruptus is used widely in Eastern Europe and the Mid-East. The only recommended application for douche is for a broken condom. Caps, made of lucite, celluloid, or metal, are used chiefly in Germany, and have the advantage of being left in place for days at a time. Spermicides usually contain nonylphenoxypolyethoxyethanol, and foam and C-film are probably the best products in effectiveness and convenience. Rhythm may be based on calendar, body temperature, or both, and its use in declining. The traditional methods should be taught and advertised, especially in countries and locales where medical services are inaccessible, such as developing countries and urban ghettos.

  16. Awareness campaigns as survival tools in the fight against gender-based violence in peri-urban communities of Bulawayo in Zimbabwe

    Directory of Open Access Journals (Sweden)

    Glory Damba

    2013-01-01

    Full Text Available Most of Zimbabwe’s urban settlements owe their existence to mining activities; hence most peri-urban communities around Bulawayo, Zimbabwe’s second largest city, are mining communities. However, research in these mining communities has shown that there is little focus on the strengthening of community dynamics that help members to cope with the challenges associated with Gender-Based Violence. Psychosocial support rarely arrives in time to effectively cover gaps left by traditional coping strategies. This paper presents and discusses experiences and insights accumulated from awareness campaigns meant to sensitise people about the nature and scope of gender-based violence. This article is a culmination of focus group discussions, informal interviews and participant observation as efforts were made towards capacity building for community members’ abilities to identify forms of risky behaviour associated with gender-based violence, and the appropriate actions members could take should they find themselves in such situations. In short, this article discusses the conceptualisation of domestic and gender violence as a risk, forms of gender-based violence, the rationale behind campaigns to reduce the internalisation of gender-based violence, and challenges faced in inculcating behaviour change efforts.

  17. (Reconstructing Balkan Identities through Popular Music

    Marin Cvitanović

    2009-12-01

    Full Text Available The paper deals with the reproduction of stereotypes about the Balkans in the popular music of ex-Yugoslavia. During the last two decades, over a hundred songs in the Serbian and Croatian languages have been released, specifically mentioning the term Balkan and using it as a metaphor – to evoke and explain the atmosphere of war, poverty, conflict and passion, beauty, love and pride. Based on the analysis of these texts and the frequency of appearance of the themes and motifs, four distinct discourses can be identified: 1. the Balkans as an area of wars and conflicts, 2. the Balkans as an area of joy, passion and fatalism, 3. the primitive and aggressive “male” Balkans vs. the beautiful, proud and resistant “female” Balkans, and 4. the Balkans as Europe’s “Other”. The results show that, despite the inherent fluidity and the unclearness of the very definition of the Balkans and its spatial coverage (and therefore the possibility of distancing oneself from it, mostly negative stereotypes about the Balkans are being reproduced. They are not questioned in that process, but accepted and affirmed as a part of one’s own identity.

    Full Text Available Libet et al. (1983 revealed that brain activity precedes conscious intention. For convenience in this study, we divide brain activity into two parts: a conscious field (CF and an unconscious field (UF. Most studies have assumed a comparator mechanism or an illusion of CF and discuss the difference of prediction and postdiction. We propose that problems to be discussed here are a twisted sense of agency between CF and UF, and another definitions of prediction and postdiction in a mediation process for the twist. This study specifically examines the definitions throughout an observational heterarchy model based on internal measurement. The nature of agency must be emergence that involves observational heterarchy. Consequently, awareness involves processes having duality in the sense that it is always open to the world (postdiction and that it also maintains self robustly (prediction.

    Feldenkrais methods appear to be gaining popularity and utilization by physical therapists. The need for scientific justification of their usage is indicated. The purpose of this study was to quantify the results of a Feldenkrais method-Awareness Through Movement-involving a neck flexion task. The study examined 30 normal subjects to determine if a Feldenkrais Awareness Through Movement sequence would result in an increase in neck flexion range of motion and if the subjects would indicate a significantly lower level of perceived effort posttest. Measurements of range of motion were taken using a gravity-based cervical range of motion goniometer. The subjects recorded their perceived efforts on a visual analogue scale. The range of motion data were analyzed using a one-way ANOVA. The visual analogue scale data were analyzed with a Mann-Whitney U test. The data supported both hypotheses. Based on these findings, further investigation of Feldenkrais methods in the treatment of patients appears warranted. J Orthop Sports Phys Ther 1992;16(1):25-29.

    Emergency responders need access to information but what counts as actionable information depends on their role, task, location, and other variables. For example, experts who have unique knowledge and experience and are called on to serve as scientific and teclmical responders, require correspondingly unique situation awareness in order to do their work. In our research-in-progress we leverage emerging and evolving web and digital library technologies to create personalized situation awareness tools that address the needs of these scientific and technical responders in real time, through focused information collection, extraction, integration, representation, and dissemination. We describe three personalized situation awareness tools in this paper: the Theme Awareness Tool (THEMAT), Social Awareness Tool (SAT), and Expertise Awareness Tool (EXPAT). The concepts and technologies we are developing in collaboration with experts apply to those who use the Web, in general, and offer an approach to the general issue of HCI design for emergencies.

    Hypertension is common in China and its prevalence is rising, yet it remains inadequately controlled. Few studies have the capacity to characterise the epidemiology and management of hypertension across many heterogeneous subgroups. We did a study of the prevalence, awareness, treatment, and control of hypertension in China and assessed their variations across many subpopulations. We made use of data generated in the China Patient-Centered Evaluative Assessment of Cardiac Events (PEACE) Million Persons Project from Sept 15, 2014, to June 20, 2017, a population-based screening project that enrolled around 1·7 million community-dwelling adults aged 35-75 years from all 31 provinces in mainland China. In this population, we defined hypertension as systolic blood pressure of at least 140 mm Hg, or diastolic blood pressure of at least 90 mm Hg, or self-reported antihypertensive medication use in the previous 2 weeks. Hypertension awareness, treatment, and control were defined, respectively, among hypertensive adults as a self-reported diagnosis of hypertension, current use of antihypertensive medication, and blood pressure of less than 140/90 mm Hg. We assessed awareness, treatment, and control in 264 475 population subgroups-defined a priori by all possible combinations of 11 demographic and clinical factors (age [35-44, 45-54, 55-64, and 65-75 years], sex [men and women], geographical region [western, central, and eastern China], urbanity [urban vs rural], ethnic origin [Han and non-Han], occupation [farmer and non-farmer], annual household income [< ¥10 000, ¥10 000-50 000, and ≥¥50 000], education [primary school and below, middle school, high school, and college and above], previous cardiovascular events [yes or no], current smoker [yes or no], and diabetes [yes or no]), and their associations with individual and primary health-care site characteristics, using mixed models.

    Gao, Qian; Fu, Deqian; Dong, Xiangjun

    2016-01-01

    In this paper, a new approach is adopted to update the user preference profile by seeking users with similar interests based on the context obtainable for a mobile network instead of from desktop networks. The trust degree between mobile users is calculated by analyzing their behavior based on the context, and then the approximate neighbors are chosen by combining the similarity of the mobile user preference and the trust degree. The approach first considers the communication behaviors between mobile users, the mobile network services they use as well as the corresponding context information. Then a similarity degree of the preference between users is calculated with the evaluation score of a certain mobile web service provided by a mobile user. Finally, based on the time attenuation function, the users with similar preference are found, through which we can dynamically update the target user’s preference profile. Experiments are then conducted to test the effect of the context on the credibility among mobile users, the effect of time decay factors and trust degree thresholds. Simulation shows that the proposed approach outperforms two other methods in terms of Recall Ratio, Precision Ratio and Mean Absolute Error, because neither of them consider the context mobile information.

    Full Text Available The proposed model holds that, at its most fundamental level, visual awareness is quantized. That is to say that visual awareness arises as individual bits of awareness through the action of neural circuits with hundreds to thousands of neurons in at least the human striate cortex. Circuits with specific topologies will reproducibly result in visual awareness that correspond to basic aspects of vision like color, motion and depth. These quanta of awareness (qualia are produced by the feedforward sweep that occurs through the geniculocortical pathway but are not integrated into a conscious experience until recurrent processing from centers like V4 or V5 select the appropriate qualia being produced in V1 to create a percept. The model proposed here has the potential to shift the focus of the search for visual awareness to the level of microcircuits and these likely exist across the kingdom Animalia. Thus establishing qualia as the fundamental nature of visual awareness will not only provide a deeper understanding of awareness, but also allow for a more quantitative understanding of the evolution of visual awareness throughout the animal kingdom.

    Cervical cancer (CC) incidence and mortality among young women have been increasing in Japan. To develop effective measures to combat this, we assessed the feasibility of using a social networking site (SNS) to recruit a representative sample of young women to conduct a knowledge and attitude study about CC prevention via an internet-based questionnaire. From July 2012 to March 2013, advertising banners targeting women aged 16 to 35 years in Kanagawa Prefecture were placed on Facebook in a similar manner as an Australian (AUS) study conducted in 16- to 25-year-olds in 2010 and on a homepage to advertise our CC advocacy activities. Eligible participants were emailed instructions for accessing our secure Web site where they completed an online survey including demographics, awareness, and knowledge of human papillomavirus (HPV) and CC. Data for the study population were compared with the general Japanese population and the AUS study. Among 394 women who expressed interest, 243 (62%) completed the survey, with 52% completing it via Facebook. Women aged 26 to 35 years, living in Yokohama City, with an education beyond high school, were overrepresented. Participants had high awareness and knowledge of HPV and CC, comparable with the AUS study participants. However, the self-reported HPV vaccination rate (22% among participants aged 16-25 years) and the recognition rate of the link between smoking and CC (31%) were significantly lower than in the AUS study (58% and 43%, respectively) (P women into health surveys, which can effectively be performed online. A nationwide survey using SNSs would be an appropriate next step to better understand the current lack of uptake of the national HPV vaccine program by young women in Japan.

    Full Text Available This study is a literature review, drawing mainly on the nine significant and good quality studies (i.e. published in peer-reviewed journals that make up the evidence base for mindful awareness practices in early childhood. Mindful awareness practices in this context means an individual’s awareness of her own body and her inner emotions or tensions. Increased awareness can decrease if individuals tend to impulsiveness or excessive stress. Self-regulation and mindful awareness skills are associated not only with stress regulation but also peer relationships and social skills. This systematic review attempts to look at the research of mindful awareness activities, programmes or interventions used as routine everyday activities. The second aim of this review is to examine the research design that has been used. The third aim of this study is to analyse the main themes and methods of these pieces of research.

    Alzheimer's disease (AD) has been not only a substantial financial burden to the health care system but also an emotional burden to patients and their families. Making accurate diagnosis of AD based on brain magnetic resonance imaging (MRI) is becoming more and more critical and emphasized at the earliest stages. However, the high dimensionality and imbalanced data issues are two major challenges in the study of computer aided AD diagnosis. The greatest limitations of existing dimensionality reduction and over-sampling methods are that they assume a linear relationship between the MRI features (predictor) and the disease status (response). To better capture the complicated but more flexible relationship, we propose a multi-kernel based dimensionality reduction and over-sampling approaches. We combined Marginal Fisher Analysis with ℓ 2,1 -norm based multi-kernel learning (MKMFA) to achieve the sparsity of region-of-interest (ROI), which leads to simultaneously selecting a subset of the relevant brain regions and learning a dimensionality transformation. Meanwhile, a multi-kernel over-sampling (MKOS) was developed to generate synthetic instances in the optimal kernel space induced by MKMFA, so as to compensate for the class imbalanced distribution. We comprehensively evaluate the proposed models for the diagnostic classification (binary class and multi-class classification) including all subjects from the Alzheimer's Disease Neuroimaging Initiative (ADNI) dataset. The experimental results not only demonstrate the proposed method has superior performance over multiple comparable methods, but also identifies relevant imaging biomarkers that are consistent with prior medical knowledge.

    A Web-based self-check system including a brief questionnaire would seem to be a suitable tool for rapid disease screening. The purpose of this preliminary study was to test a Web-based self-screening questionnaire for drawing attention to dry eye disease among general Internet users and identifying those with a higher risk of developing the condition. A survey website was launched and used to recruit participants from general Internet users. In the first phase, volunteers were asked to complete a Web-based self-screening questionnaire containing 12 questions on dry eye symptoms. The second phase focused on the respondents who reported five or more dry eye symptoms and expressed their intention to seek medical attention. These participants performed the Schirmer test, for evaluating tear production, and completed a paper-based lifestyle questionnaire to provide relevant background data. Of the 1689 visitors to the website, 980 (58.0%) volunteers completed the Web-based self-screening questionnaire. Among these, 355 (36.2%) respondents reported five or more dry eye symptoms. Then, 99 (27.9%) of the symptomatic participants performed the Schirmer test and completed the paper-based lifestyle questionnaire. Out of these, 32 (32.2%) had abnormal tear production (≤5 mm). The proposed Web-based self-screening questionnaire seems to be a promising tool for raising awareness of dry eye disease among general Internet users and identifying those with a higher risk of developing the condition, although further research is needed to validate its effectiveness.

    Half the global population lives within 60 km of the ocean, profoundly influencing environmental quality and services to local communities. Adoption of marine science curricula creates opportunities for educators and scientists to engage and entrain K-12 students as ocean stewards. In particular, boat-based science activities facilitate hands-on inquiry. These activities reinforce key science concepts while creating a tangible connection to our shared coastal "backyard." A collaboration between Zephyr Education Foundation, the New England Aquarium, the University of Massachusetts Boston and Woods Hole Oceanographic Institution has taken >500 Boston, MA area students from 26 public schools on boat-based education trips in Boston Harbor. Marine science and technology professionals and educators facilitate participatory activities using modern marine technology aboard a research vessel. Trips are funded at no cost to participants by a grant from the Richard Lounsbery Foundation; cost-free outings are essential for participation from underserved public school districts. Participants perceived three important outcomes of their outings: the trips 1) enhanced in-class curricular learning and improved marine science literacy 2) increased personal connections to local marine environments, and 3) increased interest in careers in marine science, including engineering and technical positions. Despite living in close proximity to water, this was the first boat outing for many students; boat-based education trips enhanced student awareness of local environments in a way that curricular study had not. Boston trip results are being evaluated, but 3000 evaluations from similar trips in Woods Hole, MA indicate that 98% of participants gained a better understanding and appreciation of the work conducted by marine scientists, engineers, and other professionals, and 82% said their experience made them more interested in becoming involved in science at school and/or as a job.

  19. Perirhinal and hippocampal contributions to visual recognition memory can be distinguished from those of occipito-temporal structures based on conscious awareness of prior occurrence.

    The ability of humans to distinguish consciously between new and previously encountered objects can be probed with visual recognition memory tasks that require explicit old-new discriminations. Medial temporal-lobe (MTL) lesions impair performance on such tasks. Within the MTL, both perirhinal cortex and the hippocampus have been implicated. Cognitive processes can also be affected by past object encounters in the absence of conscious recognition, as in repetition priming tasks. Past functional neuroimaging findings in healthy individuals suggest that even in tasks that require conscious recognition decisions for visual stimuli, posterior cortical structures in the ventral visual pathway distinguish between old and new objects at a nonconscious level. Conclusive evidence that differentiates the neural underpinnings of conscious from nonconscious processes in recognition memory, however, is still missing. In particular, functional magnetic resonance imaging (fMRI) findings for the MTL have been inconsistent towards this end. In the present fMRI study, we tested whether perirhinal and hippocampal contributions to recognition memory can be distinguished from those of occipito-temporal structures in the ventral visual pathway based on the participants' reported conscious awareness of prior occurrence. Images of objects with a large degree of feature overlap served as stimuli; they were selected to ensure an involvement of perirhinal cortex in the present recognition task, based on evidence from past lesion-based research. We found that both perirhinal cortex and occipito-temporal cortex showed a differential old-new response that reflected a repetition-related decrease in activity (i.e., new > old). Whereas in perirhinal cortex this decrease was observed with respect to whether subjects reported objects to be old or new, irrespective of the true item status, in occipito-temporal cortex it occurred in relation to whether objects were truly old or new, irrespective of

    Little is known about recruitment methods for racial/ethnic minority populations from resource-limited areas for community-based health and needs assessments, particularly assessments that incorporate mobile health (mHealth) technology for characterizing physical activity and dietary intake. We examined whether the Communication, Awareness, Relationships and Empowerment (C.A.R.E.) model could reduce challenges recruiting and retaining participants from faith-based organizations in predominantly African American Washington, D.C. communities for a community-based assessment. Employing C.A.R.E. model elements, our diverse research team developed partnerships with churches, health organizations, academic institutions and governmental agencies. Through these partnerships, we cultivated a visible presence at community events, provided cardiovascular health education and remained accessible throughout the research process. Additionally, these relationships led to the creation of a community advisory board (CAB), which influenced the study's design, implementation, and dissemination. Over thirteen months, 159 individuals were recruited for the study, 99 completed the initial assessment, and 81 used mHealth technology to self-monitor physical activity over 30 days. The culturally and historically sensitive C.A.R.E. model strategically engaged CAB members and study participants. It was essential for success in recruitment and retention of an at-risk, African American population and may be an effective model for researchers hoping to engage racial/ethnic minority populations living in urban communities.

    Retinex theory estimates the human color sensation at any observed point by correcting its color based on the spatial arrangement of the colors in proximate regions. We revise two recent path-based, edge-aware Retinex implementations: Termite Retinex (TR) and Energy-driven Termite Retinex (ETR). As the original Retinex implementation, TR and ETR scan the neighborhood of any image pixel by paths and rescale their chromatic intensities by intensity levels computed by reworking the colors of the pixels on the paths. Our interest in TR and ETR is due to their unique, content-based scanning scheme, which uses the image edges to define the paths and exploits a swarm intelligence model for guiding the spatial exploration of the image. The exploration scheme of ETR has been showed to be particularly effective: its paths are local minima of an energy functional, designed to favor the sampling of image pixels highly relevant to color sensation. Nevertheless, since its computational complexity makes ETR poorly practicable, here we present a light version of it, named Light Energy-driven TR, and obtained from ETR by implementing a modified, optimized minimization procedure and by exploiting parallel computing.

  2. TADL-V2: An Improved Trust-Aware Dynamic Location-based Adaptation Protocol For Discovering Multiple Paths in MANETs

    2015-08-01

    Full Text Available Mobile ad hoc networks (MANETs have a number of features that make the provisioning of Quality of Services (QoS particularly challenging. One of the most challenging issues is how to discover more reliable paths for high priority traffic delivery in a highly mobile network and do so with minimum overhead costs. This paper attempts to address this issue by designing and evaluating a multi-path discovery protocol. This protocol, named as Trust-Aware Dynamic Location-based protocol version 2 (TADL-V2, is an improved version of our earlier published protocol, TADL. TADL-V2 has improved TADL in two aspects: (1 it uses a hybrid approach to node-disjoint path discovery based on the network mobility level and (2 it uses a mobility based approach to search area resizing. These measures enable TADL-V2 to discover more paths with reduced number of control packets injected into the network. Our simulation study shows that TADL-V2 outperforms TADL in terms of reducing control overheads when the network is highly mobile. This overhead reduction can have a positive effect on QoS provisioning.

    Full Text Available Performance enhancement of Underwater Wireless Sensor Networks (UWSNs in terms of throughput maximization, energy conservation and Bit Error Rate (BER minimization is a potential research area. However, limited available bandwidth, high propagation delay, highly dynamic network topology, and high error probability leads to performance degradation in these networks. In this regard, many cooperative communication protocols have been developed that either investigate the physical layer or the Medium Access Control (MAC layer, however, the network layer is still unexplored. More specifically, cooperative routing has not yet been jointly considered with sink mobility. Therefore, this paper aims to enhance the network reliability and efficiency via dominating set based cooperative routing and sink mobility. The proposed work is validated via simulations which show relatively improved performance of our proposed work in terms the selected performance metrics.

    In cancer, clonal evolution is assessed based on information coming from single nucleotide variants and copy number alterations. Nonetheless, existing methods often fail to accurately combine information from both sources to truthfully reconstruct clonal populations in a given tumor sample or in a set of tumor samples coming from the same patient. Moreover, previously published methods detect clones from a single set of variants. As a result, compromises have to be done between stringent variant filtering (reducing dispersion in variant allele frequency estimates, VAFs) and using all biologically relevant variants. We present a framework for defining cancer clones using most reliable variants of high depth of coverage and assigning functional mutations to the detected clones. The key element of our framework is QuantumClone, a method for variant clustering into clones based on VAFs, genotypes of corresponding regions and information about tumor purity. We validated QuantumClone and our framework on simulated data. We then applied our framework to whole genome sequencing data for 19 neuroblastoma trios each including constitutional, diagnosis and relapse samples. We confirmed an enrichment of damaging variants within such pathways as MAPK, neuritogenesis, epithelial-mesenchymal transition, cell survival and DNA repair. Most pathways had more damaging variants in the expanding clones compared to shrinking ones, which can be explained by the increased total number of variants between these two populations. Functional mutational rate varied for ancestral clones and clones shrinking or expanding upon treatment, suggesting changes in clone selection mechanisms at different time points of tumor evolution.

Historically, most SSA software has been constructed with "closed" proprietary code, which limits interoperability, inhibits the code transparency that some SSA customers need to develop domain expertise, and prevents the rapid injection of innovative concepts into these systems. Open-source aerospace software, a rapidly emerging, alternative trend in code development, is based on open collaboration, which has the potential to bring greater transparency, interoperability, flexibility, and reduced development costs. Open-source software is easily adaptable, geared to rapidly changing mission needs, and can generally be delivered at lower costs to meet mission requirements. This paper outlines Ball's COSMOS C2 system, a fully open-source, web-enabled, command-and-control software architecture which provides several unique capabilities to move the current legacy SSA software paradigm to an open source model that effectively enables pre- and post-launch asset command and control. Among the unique characteristics of COSMOS is the ease with which it can integrate with diverse hardware. This characteristic enables COSMOS to serve as the command-and-control platform for the full life-cycle development of SSA assets, from board test, to box test, to system integration and test, to on-orbit operations. The use of a modern scripting language, Ruby, also permits automated procedures to provide highly complex decision making for the tasking of SSA assets based on both telemetry data and data received from outside sources. Detailed logging enables quick anomaly detection and resolution. Integrated real-time and offline data graphing renders the visualization of the both ground and on-orbit assets simple and straightforward.

  6. Health Deficits and (the Absence of Popular Mobilization in Brazil

    Full Text Available The article explains why Brazil’s popular sectors made claims for health during the 1970s and why they did not do so during the 1990s. I argue that the intervention of “external actors”—better situated individuals and social groups—makes all the difference for popular mobilization. This is because they have the skills and resources to challenge dominant ideas, construct mobilization frames and inspire belief among the popular sectors that their actions can be successful. Health movements emerged in the mid-1970s with the intervention of doctors, medical students and the Catholic Church. During the 1990s, however, these external actors largely retreated from an activist role and took up more routine activities. Based on my research in Sapopemba (São Paulo, I argue that without the engagement of middle-class professionals and progressive Church officials, the popular sectors were caught in a “cognitive trap” so that they did not believe their actions would be successful.

    Full Text Available Strategies for running companies in low-income markets have been in the spotlight in both the academic and the corporate environments.However, the first discussions about the relevance of such markets arose during the 1980s, when scenario-prospecting studies showed that popular markets would provide many opportunities around the year 2000.Indeed, at present, the base of the pyramid has many unaddressed needs that offer business possibilities for those companies that are willing to review their strategies. In this context, product development becomes increasingly important, since products targeting consumers of the C, D and E classes may need different features from those of goods manufactured for the A and B classes.The aim of this study is to revisit past popular market forecasts and to identify development trends for goods that target low- income consumers.Our results indicate that Wright and Johnson’s (1984 studies predicted that Brazil would maintain both qualitative and quantitative progress in its socioeconomic development over the next two decades and that the development of popular products is undergoing a buoyant phase.Several functional perspectives were used to develop an understanding of the phenomenon, especially marketing, engineering and manufacturing.Key words: Future studies. Popular markets. Product development.

    Full Text Available The development of digital media has brought a new challenge to existing science popularization in the rural areas. In this paper, new experience of rural science popularization on both traditional and digital media in Zhejiang province was introduced. We proposed several strategies for rural science popularization in the digital media era: First, we should strengthen the utilization of traditional platforms such as print media and broadcast and TV media. Then, digital media based on Internet should also be used for science popularization. Last but not least, we should also try to use “the fifth media” to upgrade existing platforms and create new Internet media channels.

  9. An On-Time Power-Aware Scheduling Scheme for Medical Sensor SoC-Based WBAN Systems

    Directory of Open Access Journals (Sweden)

    Jung-Guk Kim

    2012-12-01

    Full Text Available The focus of many leading technologies in the field of medical sensor systems is on low power consumption and robust data transmission. For example, the implantable cardioverter-defibrillator (ICD, which is used to maintain the heart in a healthy state, requires a reliable wireless communication scheme with an extremely low duty-cycle, high bit rate, and energy-efficient media access protocols. Because such devices must be sustained for over 5 years without access to battery replacement, they must be designed to have extremely low power consumption in sleep mode. Here, an on-time, energy-efficient scheduling scheme is proposed that performs power adjustments to minimize the sleep-mode current. The novelty of this scheduler is that it increases the determinacy of power adjustment and the predictability of scheduling by employing non-pre-emptible dual priority scheduling. This predictable scheduling also guarantees the punctuality of important periodic tasks based on their serialization, by using their worst case execution time and the power consumption optimization. The scheduler was embedded into a system on chip (SoC developed to support the wireless body area network—a wakeup-radio and wakeup-timer for implantable medical devices. This scheduling system is validated by the experimental results of its performance when used with life-time extensions of ICD devices.

    This article discusses best-selling science books, the characteristics of the audience for popular science books, and the role of books within science popularization and science education. Best-selling science books have been rare, but generally readable. Regional books, also important sources of scientific information, aim at much smaller, far more price-sensitive audiences. Many successful regional, nontechnical science books are readable, heavily illustrated, and in some cases, cross-disciplinary. To increase the attentive audience for scientific information, improvement in science education is necessary, and the most efficacious role for scientific institutions may be the production of materials that can be easily incorporated into school curricula. ?? 1991 Springer.

    Full Text Available Objective: The purpose of this study was to determine the level of knowledge of folic acidsupplementation amongst Iranian pregnant women.Materials and methods: We selected 322 women through simple randomized method in a cross sectionstudy. Data was gathered on the base of questionnaire and interview. Statistical analysis was performedusing SPSS software. The value of p<0.05 was considered as significant level.Results: The obtained information revealed that 7.8% with high level of knowledge, 43.8% withintermediate level, 30.4% with low level knowledge, and 18% with no knowledge. Hospitals and healthcenters are two major sources for promoting popular awareness about folic acid. There is a significantrelationship between the knowledge, education, employment, time of prenatal care beginning, age,gravidity, and sources of health information. The number of women with high level of knowledge wasmore among those with lower parity, higher level of education, employment, young age and looking forhealth information.Conclusion: Awareness of folic acid is low among Iranian women. The different strategies are required toelevate the knowledge about folic acid among the women in reproductive age and provide them withsome information about the benefits of this supplement.

    2017-12-01

    The MODIS Joint Atmosphere product, MODATML2 and MYDATML2 L2/3 provided by LAADS DAAC (Level-1 and Atmosphere Archive & Distribution System Distributed Active Archive Center) re-sampled from medium resolution MODIS Terra /Aqua Satellites data at 5km scale, contains Cloud Reflectance, Cloud Top Temperature, Water Vapor, Aerosol Optical Depth/Thickness, Humidity data. These re-sampled data, when used for deriving climatic effects of aerosols (particularly in case of cooling effect) still exposes limitations in presence of uncertainty measures in atmospheric artifacts such as aerosol, cloud, cirrus cloud etc. The effect of uncertainty measures in these artifacts imposes an important challenge for estimation of aerosol effects, adequately affecting precise regional weather modeling and predictions: Forecasting and recommendation applications developed largely depend on these short-term local conditions (e.g. City/Locality based recommendations to citizens/farmers based on local weather models). Our approach inculcates artificial intelligence technique for representing heterogeneous data(satellite data along with air quality data from local weather stations (i.e. in situ data)) to learn, correct and predict aerosol effects in the presence of cloud and other atmospheric artifacts, defusing Spatio-temporal correlations and regressions. The Big Data process pipeline consisting correlation and regression techniques developed on Apache Spark platform can easily scale for large data sets including many tiles (scenes) and over widened time-scale.

  17. Entropy-Based and Weighted Selective SIFT Clustering as an Energy Aware Framework for Supervised Visual Recognition of Man-Made Structures

    Directory of Open Access Journals (Sweden)

    Ayman El Mobacher

    2013-01-01

    Full Text Available Using local invariant features has been proven by published literature to be powerful for image processing and pattern recognition tasks. However, in energy aware environments, these invariant features would not scale easily because of their computational requirements. Motivated to find an efficient building recognition algorithm based on scale invariant feature transform (SIFT keypoints, we present in this paper uSee, a supervised learning framework which exploits the symmetrical and repetitive structural patterns in buildings to identify subsets of relevant clusters formed by these keypoints. Once an image is captured by a smart phone, uSee preprocesses it using variations in gradient angle- and entropy-based measures before extracting the building signature and comparing its representative SIFT keypoints against a repository of building images. Experimental results on 2 different databases confirm the effectiveness of uSee in delivering, at a greatly reduced computational cost, the high matching scores for building recognition that local descriptors can achieve. With only 14.3% of image SIFT keypoints, uSee exceeded prior literature results by achieving an accuracy of 99.1% on the Zurich Building Database with no manual rotation; thus saving significantly on the computational requirements of the task at hand.

  18. Proportional-integral and proportional-integral-derivative-based cyclic sleep controllers with anti-windup technique for energy-efficient and delay-aware passive optical networks

    2016-08-01

    In energy-efficient passive optical network (PON) systems, the increase in the queuing delays caused by the power-saving mechanism of optical network units (ONUs) is an important issue. Some researchers have proposed quality-of-service (QoS)-aware ONU cyclic sleep controllers in PON systems. We have proposed proportional (P) and proportional-derivative (PD)-based controllers to maintain the average queuing delay at a constant level regardless of the amount of downstream traffic. However, sufficient performance has not been obtained because of the sleep period limitation. In this paper, proportional-integral (PI) and proportional-integral-derivative (PID)-based controllers considering the sleep period limitation, i.e., using an anti-windup (AW) technique, are proposed to improve both the QoS and power-saving performance. Simulations confirm that the proposed controllers provide better performance than conventional controllers in terms of the average downstream queuing delay and the time occupancy of ONU active periods.

    Włodzimierz Lewoniewski

    2017-12-01

    Full Text Available Despite the fact that Wikipedia is often criticized for its poor quality, it continues to be one of the most popular knowledge bases in the world. Articles in this free encyclopedia on various topics can be created and edited in about 300 different language versions independently. Our research has showed that in language sensitive topics, the quality of information can be relatively better in the relevant language versions. However, in most cases, it is difficult for the Wikipedia readers to determine the language affiliation of the described subject. Additionally, each language edition of Wikipedia can have own rules in the manual assessing of the content’s quality. There are also differences in grading schemes between language versions: some use a 6–8 grade system to assess articles, and some are limited to 2–3. This makes automatic quality comparison of articles between various languages a challenging task, particularly if we take into account a large number of unassessed articles; some of the Wikipedia language editions have over 99% of articles without a quality grade. The paper presents the results of a relative quality and popularity assessment of over 28 million articles in 44 selected language versions. Comparative analysis of the quality and the popularity of articles in popular topics was also conducted. Additionally, the correlation between quality and popularity of Wikipedia articles of selected topics in various languages was investigated. The proposed method allows us to find articles with information of better quality that can be used to automatically enrich other language editions of Wikipedia.

    To examine how health advice is provided in popular magazines and the quality of that advice. A prospective quantitative analysis of the quality of health advice provided in Australian magazines between July and December 2011 was conducted. A rating instrument was adapted from the Media Doctor Australia rating tool used to assess quality of health news reporting. Criteria included: recommends seeing a doctor; advice based on reliable evidence; advice clear and easily applied; benefits presented meaningfully; potential harms mentioned; evidence of disease mongering; availability and cost of treatments; obvious advertising; vested interest, and anecdotal evidence. 163 health advice articles were rated showing a wide variation in the quality of advice presented between magazines. Magazines with 'health' in the title, rated most poorly with only 36% (26/73) of these articles presenting clear and meaningful advice and 52% (38/73) giving advice based on reliable evidence. Australian magazines, especially those with health in the title, generally presented poor quality, unreliable health advice. Teen magazine Dolly provided the highest quality advice.

    Major depressive disorder (MDD) is one of the current leading causes of disability worldwide. Adolescence is a vulnerable period for the onset of depression, with MDD affecting 8–20% of all youth. Traditional treatment methods have not been sufficiently effective to slow the increasing prevalence of adolescent depression. We therefore propose a new model for the treatment of adolescent depression – Training for Awareness, Resilience, and Action (TARA) – that is based on current understanding of developmental and depression neurobiology. The TARA model is aligned with the Research Domain Criteria (RDoC) of the National Institute of Mental Health. In this article, we first address the relevance of RDoC to adolescent depression. Second, we identify the major RDoC domains of function involved in adolescent depression and organize them in a way that gives priority to domains thought to be driving the psychopathology. Third, we select therapeutic training strategies for TARA based on current scientific evidence of efficacy for the prioritized domains of function in a manner that maximizes time, resources, and feasibility. The TARA model takes into consideration the developmental limitation in top-down cognitive control in adolescence and promotes bottom-up strategies such as vagal afference to decrease limbic hyperactivation and its secondary effects. The program has been informed by mindfulness-based therapy and yoga, as well as modern psychotherapeutic techniques. The treatment program is semi-manualized, progressive, and applied in a module-based approach designed for a group setting that is to be conducted one session per week for 12 weeks. We hope that this work may form the basis for a novel and more effective treatment strategy for adolescent depression, as well as broaden the discussion on how to address this challenge.

    Creative industries constantly strive for fame and popularity. Though highly desirable, popularity is not the only achievement artistic creations might ever acquire. Leaving a longstanding mark in the global production and influencing future works is an even more important achievement, usually acknowledged by experts and scholars. 'Significant' or 'influential' works are not always well known to the public or have sometimes been long forgotten by the vast majority. In this paper, we focus on the duality between what is successful and what is significant in the musical context. To this end, we consider a user-generated set of tags collected through an online music platform, whose evolving co-occurrence network mirrors the growing conceptual space underlying music production. We define a set of general metrics aiming at characterizing music albums throughout history, and their relationships with the overall musical production. We show how these metrics allow to classify albums according to their current popularity or their belonging to expert-made lists of important albums. In this way, we provide the scientific community and the public at large with quantitative tools to tell apart popular albums from culturally or aesthetically relevant artworks. The generality of the methodology presented here lends itself to be used in all those fields where innovation and creativity are in play.

  8. Significance and popularity in music production

    Creative industries constantly strive for fame and popularity. Though highly desirable, popularity is not the only achievement artistic creations might ever acquire. Leaving a longstanding mark in the global production and influencing future works is an even more important achievement, usually acknowledged by experts and scholars. ‘Significant’ or ‘influential’ works are not always well known to the public or have sometimes been long forgotten by the vast majority. In this paper, we focus on the duality between what is successful and what is significant in the musical context. To this end, we consider a user-generated set of tags collected through an online music platform, whose evolving co-occurrence network mirrors the growing conceptual space underlying music production. We define a set of general metrics aiming at characterizing music albums throughout history, and their relationships with the overall musical production. We show how these metrics allow to classify albums according to their current popularity or their belonging to expert-made lists of important albums. In this way, we provide the scientific community and the public at large with quantitative tools to tell apart popular albums from culturally or aesthetically relevant artworks. The generality of the methodology presented here lends itself to be used in all those fields where innovation and creativity are in play. PMID:28791169

  12. Character Apps for Children's Snacks: Effects of Character Awareness on Snack Selection and Consumption Patterns.

    Media characters are used to market snacks that are typically of poor nutritional value, which has been linked to childhood obesity. This study examines whether children's snack selections and consumption patterns are influenced by an app depicting a popular children's media character, as well as the role that children's awareness of the character plays. The results can increase our understanding of how to encourage healthier snack selection and consumption in newer game-based marketing venues, such as apps. Four- and 5-year-old children (N = 132) played a bowling game on an iPad with no character or with a character holding either healthier or unhealthy snacks. After app-play, children selected and consumed healthier or unhealthy snacks. Children's awareness of the character was measured by children's verbalizations of the character's name during or after app-play. An ordered logistic regression found no significant effect of treatment conditions compared with the control group. Within treatment conditions, awareness of the character led to selection and consumption of more healthy snacks in the healthier condition (odds ratio β = 10.340, P = 0.008), and of unhealthy snacks in the unhealthy condition (odds ratio β = 0.228, P = 0.033), but children were unaware that the character influenced their decisions. Results suggest that young children will choose and consume healthier, not just unhealthy, products when they are aware that a popular character in an app is associated with the snack, potentially leading to healthier eating patterns.

    Full Text Available Context aware applications, which can adapt their behaviors to changing environments, are attracting more and more attention. To simplify the complexity of developing applications, context aware middleware, which introduces context awareness into the traditional middleware, is highlighted to provide a homogeneous interface involving generic context management solutions. This paper provides a survey of state-of-the-art context aware middleware architectures proposed during the period from 2009 through 2015. First, a preliminary background, such as the principles of context, context awareness, context modelling, and context reasoning, is provided for a comprehensive understanding of context aware middleware. On this basis, an overview of eleven carefully selected middleware architectures is presented and their main features explained. Then, thorough comparisons and analysis of the presented middleware architectures are performed based on technical parameters including architectural style, context abstraction, context reasoning, scalability, fault tolerance, interoperability, service discovery, storage, security & privacy, context awareness level, and cloud-based big data analytics. The analysis shows that there is actually no context aware middleware architecture that complies with all requirements. Finally, challenges are pointed out as open issues for future work.
