    Full Text Available To effectively manage the great amount of data on Arabic web pages and to enable the classification of relevant information are very important research problems. Studies on sentiment text mining have been very limited in the Arabic language because they need to involve deep semantic processing. Therefore, in this paper, we aim to retrieve machine-understandable data with the help of a Web content mining technique to detect covert knowledge within these data. We propose an approach to achieve clustering with semantic similarities. This approach comprises integrating k-means document clustering with semantic feature extraction and document vectorization to group Arabic web pages according to semantic similarities and then show the semantic annotation. The document vectorization helps to transform text documents into a semantic class probability distribution or semantic class density. To reach semantic similarities, the approach extracts the semantic class features and integrates them into the similarity weighting schema. The quality of the clustering result has evaluated the use of the purity and the mean intra-cluster distance (MICD evaluation measures. We have evaluated the proposed approach on a set of common Arabic news web pages. We have acquired favorable clustering results that are effective in minimizing the MICD, expanding the purity and lowering the runtime.

    Full Text Available Student psychological counseling is one of the means to acknowledge student identity by employing counseling tools that allow the psychologist to make use of a set of skills essential in achieving envisaged outcomes. To act as counseling psychologist for students is to guide actions by the five wh- questions: who (the client is, why (the counselor is approached, who (the counselor talks to, what (problem the student has to tackle, how (the problem can be solved. Some of the most important features that contribute to solving student problems are the counselor’s deontology, trustworthiness and attitude that are to be relied on without impeding the client’s personality traits. Thus, developing awareness of the features underlying student psychological counseling and acting accordingly is the real test for any professional in the field. Therefore, the real challenge is not being in the lion’s den, but living with it.

    2013-02-01

    Full Text Available Duplicate and near-duplicate web pages are the chief concerns for web search engines. In reality, they incur enormous space to store the indexes, ultimately slowing down and increasing the cost of serving results. A variety of techniques have been developed to identify pairs of web pages that are aldquo;similarardquo; to each other. The problem of finding near-duplicate web pages has been a subject of research in the database and web-search communities for some years. In order to identify the near duplicate web pages, we make use of sentence level features along with fingerprinting method. When a large number of web documents are in consideration for the detection of web pages, then at first, we use K-mode clustering and subsequently sentence feature and fingerprint comparison is used. Using these steps, we exactly identify the near duplicate web pages in an efficient manner. The experimentation is carried out on the web page collections and the results ensured the efficiency of the proposed approach in detecting the near duplicate web pages.

    2014-01-01

    The increased popularity of the web has caused the inclusion of huge amount of information to the web, and as a result of this explosive information growth, automated web page classification systems are needed to improve search engines' performance. Web pages have a large number of features such as HTML/XML tags, URLs, hyperlinks, and text contents that should be considered during an automated classification process. The aim of this study is to reduce the number of features to be used to improve runtime and accuracy of the classification of web pages. In this study, we used an ant colony optimization (ACO) algorithm to select the best features, and then we applied the well-known C4.5, naive Bayes, and k nearest neighbor classifiers to assign class labels to web pages. We used the WebKB and Conference datasets in our experiments, and we showed that using the ACO for feature selection improves both accuracy and runtime performance of classification. We also showed that the proposed ACO based algorithm can select better features with respect to the well-known information gain and chi square feature selection methods.

  10. Socorro Students Translate NRAO Web Pages Into Spanish

    2002-07-01

    Six Socorro High School students are spending their summer working at the National Radio Astronomy Observatory (NRAO) on a unique project that gives them experience in language translation, World Wide Web design, and technical communication. Under the project, called "Un puente a los cielos," the students are translating many of NRAO's Web pages on astronomy into Spanish. "These students are using their bilingual skills to help us make basic information about astronomy and radio telescopes available to the Spanish-speaking community," said Kristy Dyer, who works at NRAO as a National Science Foundation postdoctoral fellow and who developed the project and obtained funding for it from the National Aeronautics and Space Administration. The students are: Daniel Acosta, 16; Rossellys Amarante, 15; Sandra Cano, 16; Joel Gonzalez, 16; Angelica Hernandez, 16; and Cecilia Lopez, 16. The translation project, a joint effort of NRAO and the NM Tech physics department, also includes Zammaya Moreno, a teacher from Ecuador, Robyn Harrison, NRAO's education officer, and NRAO computer specialist Allan Poindexter. The students are translating NRAO Web pages aimed at the general public. These pages cover the basics of radio astronomy and frequently-asked questions about NRAO and the scientific research done with NRAO's telescopes. "Writing about science for non-technical audiences has to be done carefully. Scientific concepts must be presented in terms that are understandable to non-scientists but also that remain scientifically accurate," Dyer said. "When translating this type of writing from one language to another, we need to preserve both the understandability and the accuracy," she added. For that reason, Dyer recruited 14 Spanish-speaking astronomers from Argentina, Mexico and the U.S. to help verify the scientific accuracy of the Spanish translations. The astronomers will review the translations. The project is giving the students a broad range of experience. "They are

    Rus, Holly M; Cameron, Linda D

    2016-10-01

    Social media provides unprecedented opportunities for enhancing health communication and health care, including self-management of chronic conditions such as diabetes. Creating messages that engage users is critical for enhancing message impact and dissemination. This study analyzed health communications within ten diabetes-related Facebook pages to identify message features predictive of user engagement. The Common-Sense Model of Illness Self-Regulation and established health communication techniques guided content analyses of 500 Facebook posts. Each post was coded for message features predicted to engage users and numbers of likes, shares, and comments during the week following posting. Multi-level, negative binomial regressions revealed that specific features predicted different forms of engagement. Imagery emerged as a strong predictor; messages with images had higher rates of liking and sharing relative to messages without images. Diabetes consequence information and positive identity predicted higher sharing while negative affect, social support, and crowdsourcing predicted higher commenting. Negative affect, crowdsourcing, and use of external links predicted lower sharing while positive identity predicted lower commenting. The presence of imagery weakened or reversed the positive relationships of several message features with engagement. Diabetes control information and negative affect predicted more likes in text-only messages, but fewer likes when these messages included illustrative imagery. Similar patterns of imagery's attenuating effects emerged for the positive relationships of consequence information, control information, and positive identity with shares and for positive relationships of negative affect and social support with comments. These findings hold promise for guiding communication design in health-related social media.

    Millennials has been a word of mouth of everybody and a target market of various companies nowadays. In the Philippines, they comprise one third of the total population and most of them are still in school. Having a good education system is important for this generation to prepare them for better careers. And a good education system means having quality instruction as one of the input component indicators. In a classroom environment, teachers use facial features to measure the affect state of the class. Emerging technologies like Affective Computing is one of today’s trends to improve quality instruction delivery. This, together with computer vision, can be used in analyzing affect states of the students and improve quality instruction delivery. This paper proposed a system of classifying student engagement using facial features. Identifying affect state, specifically Millennial Filipino student engagement, is one of the main priorities of every educator and this directed the authors to develop a tool to assess engagement percentage. Multiple face detection framework using Face API was employed to detect as many student faces as possible to gauge current engagement percentage of the whole class. The binary classifier model using Support Vector Machine (SVM) was primarily set in the conceptual framework of this study. To achieve the most accuracy performance of this model, a comparison of SVM to two of the most widely used binary classifiers were tested. Results show that SVM bested RandomForest and Naive Bayesian algorithms in most of the experiments from the different test datasets.

    There is increasing evidence that students at different levels of training may benefit from different methods of learning clinical reasoning. Two of the common methods of teaching are the "whole - case" format and the "serial cue" approach. There is little empirical evidence to guide teachers as to which method to use and when to introduce them. We observed 23 students from different stages of training to examine how they were taking a history and how they were thinking whilst doing this. Each student interviewed a simulated patient who presented with a straightforward and a complex presentation. We inferred how students were reasoning from how they took a history and how they described their thinking while doing this. Early in their training students can only take a generic history. Only later in training are they able to take a focused history, remember the information they have gathered, use it to seek further specific information, compare and contrast possibilities and analyze their data as they are collecting it. Early in their training students are unable to analyze data during history taking. When they have started developing illness scripts, they are able to benefit from the "serial cue" approach of teaching clinical reasoning.

    Full Text Available The research identifies the complexity level of eight texts from Spotlight 11 used in Russian TEFL to prepare students for National Unified Exam in English and assess their reading skills. The results of the analyses conducted with the help of T.E.R.A., an automated text processor, prove that all texts fell within the range of 6 – 9 Flesch-Kincaid grade levels which correspond to the English language proficiency of the target audience. We also revealed the absence of a clear progression in difficulty across the eight texts in the continuum which may cause unpredictable test results and contribute to de-motivation of students. The results also show that the indices of narrativity, syntactic simplicity, word concreteness, referential cohesion and deep cohesion measured with T.E.R.A. do not grow but fluctuate across the continuum of the texts either. Aiming at selecting authentic texts with steadily growing complexity of each of the above mentioned parameters, we recommend to incorporate the suggested algorithm of text analysis into TEFL practice in Russia. T.E.R.A. is viewed by the authors as a tool able to provide educators with a solid foundation to select texts, develop curriculum, design assessment tasks and otherwise address academic needs of a target audience.

    Body dysmorphic disorder (BDD) is a distressing psychiatric disorder. So far there have not been any studies on BDD in Saudi Arabia. The aim of this study was to determine the prevalence of body dysmorphic disorder in female medical students and to investigate whether there is an association between BDD and body features of concern, social anxiety and symptoms of BDD. A cross sectional study was carried out on female medical students of the college of medicine, King Saud University, Riyadh, Saudi Arabia during January to April, 2015. Data were collected using the body image disturbance questionnaire, Body dysmorphic disorder symptomatology and social interaction anxiety scale. Descriptive statistics, bivariate and multivariate analysis were used to analyze the results. Out of 365 students who filled out the questionnaire, 4.4% (95% confidence intervals (CI): 2.54% to 7.04%) were positive for BDD with skin (75%) and fat (68.8%) as the most frequent body features of concern. Ten features (skin, fat, chest, hips, buttocks, arms, legs, lips, fingers, and shoulders) out of twenty-six were significantly associated with BDD. Arms and chest were independently associated with BDD. The odds of presence of body concern related to "arms" was 4.3 (95% C.I: 1.5, 12.1) times more in BDD subjects than non-BDD subjects, while concern about "chest" was 3.8 (1.3, 10.9) times more when compared to non-BDD subjects. No statistically significant association was observed between BDD and social anxiety (P = 0.13). This was the first study conducted in Kingdom of Saudi Arabia (KSA) on female medical students, which quantified the prevalence of BDD and identified the body features associated with it. Body dysmorphic disorder is prevalent in female medical students but it is relatively rare and an unnoticed disorder.

    Full Text Available Dyslexia is a permanent condition characterized by reading difficulties that include inaccurate or slow and effortful word reading, poor decoding, and poor spelling abilities. People with dyslexia may have psychological and psychopathological issues such as low self-esteem, poor resilience, and symptoms of depression and anxiety. They may also develop social problems and emotional issues, as well as low academic and social self-efficacy. The present study aimed to assess the psychological features of a sample of 28 Italian university students with dyslexia, comparing them with a control group of typically-developing students matched for gender, education, and academic discipline, to enhance our knowledge of dyslexia outcomes in an Italian setting. The results show that university students with dyslexia experience higher levels of somatic complaints, social and attentional problems, lower self-esteem, and higher depression scores than controls, while no difference emerged between the two groups’ resilience scores. In conclusion, the present findings suggest that university students with dyslexia report more psychological issues than students without dyslexia and could benefit from intervention to improve their psychological and physical well-being.

    Sobkin V.S.

    2015-09-01

    Full Text Available The paper presents outcomes of a research on features of perception of modern Russian political leaders in young people. A technique of multidimensional semantic differential was employed: the subjects were asked to assess 15 objects (political leaders, 'my ideal', 'ideal leader', 'antipathetic person' and 'Myself' according to 33 personality traits using a seven-point scale. The outcomes suggest that the structure of the students' perception of political leaders is quite simple and is based on three modalities: 'morality', 'power' and 'intelligence'. Comparing these outcomes with the research data obtained in 2004 using the same technique allowed the authors to conclude that the students do not assess modern political leaders according to the moral qualities of the latter, but rather perceive them through the qualities of power associated with social manipulation.

    Full Text Available Shaping professional reflection of future teachers is of particular importance in the context of the modernization of the Russian education. However, despite the deep reflection of a problem in Russian pedagogical science the characteristics of development levels of pedagogical reflection among future teacher remains largely fragmented. The paper deals with professional and pedagogical reflection as a process of perceiving essential features of educational process by a teacher, summarizes the main theoretical and methodological approaches to this issue. The research is aimed to identify and describe levels of professional and pedagogical reflection among students. The research is divided in several stages: the stage of theoretical allocation of substantial components of professional pedagogical reflection, the stage of selecting proper research tools, ascertaining stage, and concluding stage. The conceptual basis of the research is to identify the main components that determine the following features of professional and pedagogical reflection: motivational, creative, emotional volitional, communicative, monitoring and evaluative. Based on the empirical results the levels of professional and pedagogical reflection of the students of the teacher-training specialties are identified. The first level is characterized by weak professional reflection and undifferentiated consciousness, self-awareness and self-esteem in the normal course of activities, the second level is associated with certain reflective activity and organization and is characterized by steady demand for professional and personal self-improvement. The indicator of the third level is high development of all components of professional reflection.

    One of the objectives of science education in science centres has been the enhancement of interest in science. However, museum fatigue has a negative impact on interest. Museum fatigue has been described as physical tiredness or a decrease in visitors' interest in a museum. The learning experience of students in science centres is also influenced by museum fatigue. The purpose of this study is to identify the phenomena of museum fatigue in science centres and to identity how it is manifested. First, we identified the factors causing museum fatigue in science centres using the data from an open-ended questionnaire which was given to 597 primary, middle and high school students in South Korea. From the responses to the questionnaire, 50 factors causing museum fatigue in science centres were identified. A second Likert-type questionnaire with the 50 factors of museum fatigue in science centres was administered to 610 primary, middle and high school students in South Korea. Using reliability and factor analyses, we developed a framework of the factors causing museum fatigue in science centres, which consists of three contexts, 12 categories and 50 factors. Secondly, through statistical analyses including T test and ANOVA analysis, the features of students' museum fatigue in science centres were analysed and compared regarding student gender, school level, interest in science, grade of school science, the number of visits, and type of visit. The results, which were found to be statistically significant, are reported and discussed. The findings of this study are intended to serve for a deeper understanding and practical improvement of science learning in science centres.

  2. Exploiting link structure for web page genre identification

    2015-01-01

    As the World Wide Web develops at an unprecedented pace, identifying web page genre has recently attracted increasing attention because of its importance in web search. A common approach for identifying genre is to use textual features that can be extracted directly from a web page, that is, On-Page features. The extracted features are subsequently inputted into a machine learning algorithm that will perform classification. However, these approaches may be ineffective when the web page contains limited textual information (e.g., the page is full of images). In this study, we address genre identification of web pages under the aforementioned situation. We propose a framework that uses On-Page features while simultaneously considering information in neighboring pages, that is, the pages that are connected to the original page by backward and forward links. We first introduce a graph-based model called GenreSim, which selects an appropriate set of neighboring pages. We then construct a multiple classifier combination module that utilizes information from the selected neighboring pages and On-Page features to improve performance in genre identification. Experiments are conducted on well-known corpora, and favorable results indicate that our proposed framework is effective, particularly in identifying web pages with limited textual information. © 2015 The Author(s)

    Dishonesty in academic settings is a reckless behavior that is unique to students and is associated with cheat    ing and plagiarism of academic tasks. Incidents involving dishonesty in higher education have increased considerably in the past decade, with regard to the extent of these practices, the types of dishonesty employed, and their prevalence. The current study examines the profile of "academic offenders". Which types are more prone to commit academic offenses? To what degree are they "normative" and do they represent the average student with regard to personal traits, personal perceptions, features of their academic studies, risk behaviors, and health risks. The study is based on a structured anonymous questionnaire. The sample consisted of 1,432 students, of whom 899 were female (63%) and 533 male (37%). The research findings indicate a common tendency among more than one quarter of the sample reported cheating on homework and 12.5% reported cheating on tests. Strong associations were found between academic dishonesty and various personal perceptions, the academic study experience, and involvement in other risky and deviant behaviors. Significant predictors of academic dishonesty were found, i.e., self-image, ethics, grades, time devoted to homework, and deviant and daring behaviors. The research findings might help indicate policies for optimally dealing with dishonesty, maybe even before the offense is committed, by means of cooperation between academic forces.

  19. Assessing the impact of representational and contextual problem features on student use of right-hand rules

    Science.gov (United States)

    Kustusch, Mary Bridget

    2016-06-01

    Students in introductory physics struggle with vector algebra and these challenges are often associated with contextual and representational features of the problems. Performance on problems about cross product direction is particularly poor and some research suggests that this may be primarily due to misapplied right-hand rules. However, few studies have had the resolution to explore student use of right-hand rules in detail. This study reviews literature in several disciplines, including spatial cognition, to identify ten contextual and representational problem features that are most likely to influence performance on problems requiring a right-hand rule. Two quantitative measures of performance (correctness and response time) and two qualitative measures (methods used and type of errors made) were used to explore the impact of these problem features on student performance. Quantitative results are consistent with expectations from the literature, but reveal that some features (such as the type of reasoning required and the physical awkwardness of using a right-hand rule) have a greater impact than others (such as whether the vectors are placed together or separate). Additional insight is gained by the qualitative analysis, including identifying sources of difficulty not previously discussed in the literature and revealing that the use of supplemental methods, such as physically rotating the paper, can mitigate errors associated with certain features.

    2018-01-01

    Full Text Available This study addressed school-contextual features of social disorder in relation to sixth-grade students’ experiences of bullying victimization and mental health complaints. It investigated, firstly, whether the school’s concentrations of behavioural problems were associated with individual students’ likelihood of being bullied, and secondly, whether the school’s concentrations of behavioural problems and bullying victimization predicted students’ emotional and psychosomatic health complaints. The data were derived from the Swedish National Survey of Mental Health among Children and Young People, carried out among sixth-grade students (approximately 12–13 years old in Sweden in 2009. The analyses were based on information from 59,510 students distributed across 1999 schools. The statistical method used was multilevel modelling. While students’ own behavioural problems were associated with an elevated risk of being bullied, attending a school with a higher concentration of students with behavioural problems also increased the likelihood of being bullied. Attending a school with higher levels of bullying victimization and behavioural problems predicted more emotional and psychosomatic complaints, even when adjusting for their individual level analogues. The findings indicate that school-level features of social disorder influence bullying victimization and mental health complaints among students.

    2015-02-01

    Students' perceptions of their learning environment influence the quality of outcomes they achieve. Learning dental operative techniques in a simulated clinic environment is characterised by reciprocal interactions between skills training, staff- and student-related factors. However, few studies have examined how students perceive their operative learning environments and whether there is a relationship between their perceptions and subsequent performance. Therefore, this study aimed to clarify which learning activities and interactions students perceived as supporting their operative skills learning and to examine relationships with their outcomes. Longitudinal data about examples of operative laboratory sessions that were perceived as effective or ineffective for learning were collected twice a semester, using written critical incidents and interviews. Emergent themes from these data were identified using thematic analysis. Associations between perceptions of learning effectiveness and performance were analysed using chi-square tests. Students indicated that an effective learning environment involved interactions with tutors and peers. This included tutors arranging group discussions to clarify processes and outcomes, providing demonstrations and constructive feedback. Feedback focused on mistakes, and not improvement, was reported as being ineffective for learning. However, there was no significant association between students' perceptions of the effectiveness of their learning experiences and subsequent performance. It was clear that learning in an operative technique setting involved various factors related not only to social interactions and observational aspects of learning but also to cognitive, motivational and affective processes. Consistent with studies that have demonstrated complex interactions between students, their learning environment and outcomes, other factors need investigation. © 2014 John Wiley & Sons A/S.

    2017-04-01

    This study investigates the relationship between political consumerism and core political values (CPVs) among university students in Brazil (N = 414) and Germany (N = 222). Despite the prerequisite to endorse values that are compatible with political consumerism, contextual features of one's immediate environment might affect overall levels of political consumerism. Our results show that political consumerism is significantly associated with higher income in Brazil (but not in Germany). After controlling for income, political consumerism was practised more frequently in Germany than in Brazil, in urban compared with rural areas, and was not dependent on gender. The urban-rural split was stronger in Brazil than in Germany. These results confirm our hypothesis that contextual features are associated with political consumerism. Furthermore, the political value Equality positively predicted political consumerism in both countries. In contrast, Traditional Morality and support of Free Enterprise negatively predicted political consumerism, although the effect sizes of these relationships were only small. These results suggest that political consumerism among university students is widespread in Germany but not in Brazil. Interestingly, regardless of its low prevalence in Brazil, political consumerism is positively associated with the CPV of Equality among university students in both countries. © 2015 International Union of Psychological Science.

  18. Medical students and professional anatomists do not perceive gender bias within imagery featuring anatomy.

    Morgan, Susan; Plaisant, Odile; Lignier, Baptiste; Moxham, Bernard J

    2017-09-01

    Previous studies suggest that, while both medical students and professional anatomists recognize the importance of gender issues and do not wish to associate with sexism, most are unaware of the possible negative aspects of sexism within anatomy (Morgan et al. , J. Anat. 224:352-365; , Clin. Anat. 29:892-910). To further investigate this issue, we provided second year medical students at Cardiff University (n = 293) and at the University of Paris Descartes, Sorbonne Paris Cité (n = 142) and professional anatomists (n = 208) with a questionnaire inviting them to address the possibility that gender factors within anatomical imagery (both historical and contemporary) hinder the dispassionate representation of anatomy. Ethical approval for the survey was obtained from the universities at both Cardiff and Paris. In the light of previous findings, the hypothesis tested was that medical students and professional anatomists do not perceive a gender bias when reflected in imagery that is based on anatomical iconography. Our survey results support this hypothesis and suggest that most students and anatomists are unaware of the possible negative aspects of sexism within the culture of anatomy. We consequently recommend that teachers of anatomy and authors of anatomical textbooks should be aware of the possibility of adverse effects on professional matters relating to equality and diversity issues when using imagery.

    Full Text Available The present study attempts to investigate the nature of information seeking behavior in the sample population of 158 graduate students and examine the role of personality factors in their information seeking behavior. Two questionnaires were used. Pearson correlation analysis and multi-valued regression analysis were employed in analyzing the data. Findings indicate that there is a positive significance between students’ extroversion and relevance judgment, positing of new ideas, time as a motivating factor, and effort to seek out information. A similar indication was observed between interpolation of experience and time slated for searching for information. Generally it could be deduced that there is a significant relationship between personality features and information seeking behavior of graduate students.

    Full Text Available Anxiety and depression are important health problems, because of the high prevalence rates in normal population and in clinical population. This non-experimental study intends to identify the cognitive profile, through the early maladaptive schemes in students from the Universidad Pontificia Bolivariana Bucaramanga, related with depression and anxiety scores. Thegoal is to contribute to the identification of cognitive characteristics that could help in the prevention of these disorders. 259 psychology students of the first seven semesters were evaluated by means from the following questionnaires: BDI, ST/DEP, STAI and YSQ-L2. The results don’t show the presence of specific schemes as a function of the presence of State/ Trait depression or State/Trait anxiety, which might suggest, through the dimensional paradigm, the presence of a cognitive pattern for an anxiety and depression mix disorder. It is suggested that further research should be carried out with other samples, including clinical population.

    2016-01-01

    Research has suggested that teaching and learning in molecular and cellular biology (MCB) is difficult. We used a new lens to understand undergraduate reasoning about molecular mechanisms: the knowledge-integration approach to conceptual change. Knowledge integration is the dynamic process by which learners acquire new ideas, develop connections between ideas, and reorganize and restructure prior knowledge. Semistructured, clinical think-aloud interviews were conducted with introductory and upper-division MCB students. Interviews included a written conceptual assessment, a concept-mapping activity, and an opportunity to explain the biomechanisms of DNA replication, transcription, and translation. Student reasoning patterns were explored through mixed-method analyses. Results suggested that students must sort mechanistic entities into appropriate mental categories that reflect the nature of MCB mechanisms and that conflation between these categories is common. We also showed how connections between molecular mechanisms and their biological roles are part of building an integrated knowledge network as students develop expertise. We observed differences in the nature of connections between ideas related to different forms of reasoning. Finally, we provide a tentative model for MCB knowledge integration and suggest its implications for undergraduate learning. © 2016 K. Southard et al.

Using extensive numerical simulations of large web networks, with a special accent on British University networks, we determine numerically and analytically the universal features of the PageRank vector at its emergence when {alpha} {yields} 1. The whole network can be divided into a core part and a group of invariant subspaces. For {alpha} {yields} 1, PageRank converges to a universal power-law distribution on the invariant subspaces whose size distribution also follows a universal power law. The convergence of PageRank at {alpha} {yields} 1 is controlled by eigenvalues of the core part of the Google matrix, which are extremely close to unity, leading to large relaxation times as, for example, in spin glasses.

    The PageRank algorithm enables us to rank the nodes of a network through a specific eigenvector of the Google matrix, using a damping parameter α ∈ ]0, 1[. Using extensive numerical simulations of large web networks, with a special accent on British University networks, we determine numerically and analytically the universal features of the PageRank vector at its emergence when α → 1. The whole network can be divided into a core part and a group of invariant subspaces. For α → 1, PageRank converges to a universal power-law distribution on the invariant subspaces whose size distribution also follows a universal power law.

    This study investigates the variations of Heart Rate Variability (HRV) due to a real-life stressor and proposes a classifier based on nonlinear features of HRV for automatic stress detection. 42 students volunteered to participate to the study about HRV and stress. For each student, two recordings were performed: one during an on-going university examination, assumed as a real-life stressor, and one after holidays. Nonlinear analysis of HRV was performed by using Poincaré Plot, Approximate Entropy, Correlation dimension, Detrended Fluctuation Analysis, Recurrence Plot. For statistical comparison, we adopted the Wilcoxon Signed Rank test and for development of a classifier we adopted the Linear Discriminant Analysis (LDA). Almost all HRV features measuring heart rate complexity were significantly decreased in the stress session. LDA generated a simple classifier based on the two Poincaré Plot parameters and Approximate Entropy, which enables stress detection with a total classification accuracy, a sensitivity and a specificity rate of 90%, 86%, and 95% respectively. The results of the current study suggest that nonlinear HRV analysis using short term ECG recording could be effective in automatically detecting real-life stress condition, such as a university examination.

    Facebook is the most popular social media site visited by university students on a daily basis. Consequently, Facebook is the logical place to start with for integrating social media technologies into education. This study explores how a faculty-administered Facebook Page can be used to supplement anatomy education beyond the traditional classroom. Observations were made on students' perceptions and effectiveness of using the Page, potential benefits and challenges of such use, and which Insights metrics best reflect user's engagement. The Human Anatomy Education Page was launched on Facebook and incorporated into anatomy resources for 157 medical students during two academic years. Students' use of Facebook and their perceptions of the Page were surveyed. Facebook's "Insights" tool was also used to evaluate Page performance during a period of 600 days. The majority of in-class students had a Facebook account which they adopted in education. Most students perceived Human Anatomy Education Page as effective in contributing to learning and favored "self-assessment" posts. The majority of students agreed that Facebook could be a suitable learning environment. The "Insights" tool revealed globally distributed fans with considerable Page interactions. The use of a faculty-administered Facebook Page provided a venue to enhance classroom teaching without intruding into students' social life. A wider educational use of Facebook should be adopted not only because students are embracing its use, but for its inherent potentials in boosting learning. The "Insights" metrics analyzed in this study might be helpful when establishing and evaluating the performance of education-oriented Facebook Pages. © 2013 American Association of Anatomists.

    The transition from adolescence to early adulthood is a critical period in which there is a decline in physical activity (PA). College and university students make up a large segment of this age group. Smartphones may be used to promote and support PA. The purpose of this qualitative study was to explore Dutch students' preferences regarding a PA application (PA app) for smartphones. Thirty Dutch students (aged 18-25 years) used a PA app for three weeks and subsequently attended a focus group discussion (k = 5). To streamline the discussion, a discussion guide was developed covering seven main topics, including general app usage, usage and appreciation of the PA app, appreciation of and preferences for its features and the sharing of PA accomplishments through social media. The discussions were audio and video recorded, transcribed and analysed according to conventional content analysis. The participants, aged 21 ± 2 years, were primarily female (67%). Several themes emerged: app usage, technical aspects, PA assessment, coaching aspects and sharing through social media. Participants most often used social networking apps (e.g., Facebook or Twitter), communication apps (e.g., WhatsApp) and content apps (e.g., news reports or weather forecasts). They preferred a simple and structured layout without unnecessary features. Ideally, the PA app should enable users to tailor it to their personal preferences by including the ability to hide features. Participants preferred a companion website for detailed information about their accomplishments and progress, and they liked tracking their workout using GPS. They preferred PA apps that coached and motivated them and provided tailored feedback toward personally set goals. They appreciated PA apps that enabled competition with friends by ranking or earning rewards, but only if the reward system was transparent. They were not willing to share their regular PA accomplishments through social media unless they were

The sample (N=62 included 22 education and universal values and also self-attitude parameters using the four types of emotional attitude to learning. These types of motivation profile were obtained via pre-factorization estimates of the seven values of school life using the method of semantic differential, which allowed to estimate the severity of a positional or status motivation (1, achievement motivation (2, learning and cognitive motivation, (3 and motivation of affiliation (4. This enabled to further estimate the factor and correlation analysis of the parameters studied, which shows that the system of values is significantly different in males and females of the same age, even in relation to the same mean value of motivation. Motivation, values and self-attitude organize stable systems – on the current sample allocated the four most common systems, i.e. the four factors that are specific for both males and females. Simultaneously, there are systems of values dependent on expressiveness and the combination of a certain type of motivation, and independent of the type of motivation. Female educational and cognitive motivation and positional (status motivation related to the values were merged into one factor, but for males one factor includes achievement motivation and (with the opposite sign affiliation motivation. While the self-realization of females occurs in the process of learning (the value of «selfimprovement in their studies», and in the future they see an opportunity for self-realization through the value of «happy family life», the males with this motivation connect their opportunity for self-realization with other values, i.e. «health», «recognition by other team members», «my authority.»

    Epidemiologic research indicates that psychosis and depression most frequently develop during adolescence. Hence, an efficient strategy for improving youth mental health would be to focus on detection of early-stage psychosis and depression in adolescence. In this study, 1461 high school students were surveyed using self-report scales. Students who scored equal to or above the cut-off value on any of the scales and who agreed to a further examination proceeded to a second assessment, using the Kiddie Schedule for Affective Disorders and Schizophrenia and Comprehensive Assessment of At-Risk Mental States along with self-reporting scales. The estimated prevalence of adolescents at ultra-high risk (UHR) for psychosis and of depression-spectrum disorders was 1.26 and 3.69% respectively. Compared with the normal group, experiences of bullying, suicidal ideation, and suicide attempts were significantly higher in these two groups; the subjects at UHR for psychosis were found to have significantly lower academic performance and lower ratings on SCRS; and submissive behavior was more prevalent in the depression-spectrum group. Our results reveal several clinical features of adolescents at UHR for psychosis and with depression-spectrum disorder and underscore the importance of accurate assessment of and early appropriate care for these adolescents.

    With the rapid development of the World Wide Web, people benefit more and more from the sharing of information. However, Web pages with obscene, harmful, or illegal content can be easily accessed. It is important to recognize such unsuitable, offensive, or pornographic Web pages. In this paper, a novel framework for recognizing pornographic Web pages is described. A C4.5 decision tree is used to divide Web pages, according to content representations, into continuous text pages, discrete text pages, and image pages. These three categories of Web pages are handled, respectively, by a continuous text classifier, a discrete text classifier, and an algorithm that fuses the results from the image classifier and the discrete text classifier. In the continuous text classifier, statistical and semantic features are used to recognize pornographic texts. In the discrete text classifier, the naive Bayes rule is used to calculate the probability that a discrete text is pornographic. In the image classifier, the object's contour-based features are extracted to recognize pornographic images. In the text and image fusion algorithm, the Bayes theory is used to combine the recognition results from images and texts. Experimental results demonstrate that the continuous text classifier outperforms the traditional keyword-statistics-based classifier, the contour-based image classifier outperforms the traditional skin-region-based image classifier, the results obtained by our fusion algorithm outperform those by either of the individual classifiers, and our framework can be adapted to different categories of Web pages.

    The objective of this study was to clarify the educational effect of a lecture on differential imaging features comparing ameloblastomas and keratocystic odontogenic tumors of the mandibles presented to dental students. Panoramic and CT images of 10 ameloblastomas and 10 keratocystic odontogenic tumors were randomly presented 114 dental students. Test scores, correct answer ratios, identification index, and understanding of the imaging features contributing to a correct diagnosis were serially evaluated before and after the lecture on the differential imaging features comparing the two types of tumors. The mean and standard deviation of the scoring ratios of dental students diagnosing these lesions on panoramic and CT images were 48.8±10.8% and 52.5±12.9%, respectively. After the lecture on the differential imaging features comparing the two tumors, the scoring ratios improved significantly. After the lecture, both the numbers of patients whose images were correctly diagnosed and the identification indices increased. The lecture also increased the number of imaging features recognized as contributing to the correct diagnosis. A lecture on the differential imaging features comparing ameloblastomas and keratocystic odontogenic tumors of the mandibles contributed to the improvement of imaging diagnosis skills among dental students.

    The aim of this study was to investigate the relationship of Internet addiction (IA) risk with the severity of borderline personality features, childhood traumas, dissociative experiences, depression and anxiety symptoms among Turkish university students. A total of 271 Turkish university students participated in this study. The students were assessed through the Internet Addiction Scale (IAS), the Borderline Personality Inventory (BPI), the Dissociative Experiences Scale (DES), the Childhood Trauma Questionnaire (CTQ-28), the Beck Depression Inventory (BDI) and the Beck Anxiety Inventory (BAI). The rates of students were 19.9% (n=54) in the high IA risk group, 38.7% (n=105) in the mild IA risk group and 41.3% (n=112) in the group without IA risk. Correlation analyses revealed that the severity of IA risk was related with BPI, DES, emotional abuse, CTQ-28, depression and anxiety scores. Univariate covariance analysis (ANCOVA) indicated that the severity of borderline personality features, emotional abuse, depression and anxiety symptoms were the predictors of IAS score, while gender had no effect on IAS score. Among childhood trauma types, emotional abuse seems to be the main predictor of IA risk severity. Borderline personality features predicted the severity of IA risk together with emotional abuse, depression and anxiety symptoms among Turkish university students.

    The Features area of JCE Online is now readily accessible through a single click from our home page. In the Features area each column is linked to its own home page. These column home pages also have links to them from the online Journal Table of Contents pages or from any article published as part of that feature column. Using these links you can easily find abstracts of additional articles that are related by topic. Of course, JCE Online+ subscribers are then just one click away from the entire article. Finding related articles is easy because each feature column "site" contains links to the online abstracts of all the articles that have appeared in the column. In addition, you can find the mission statement for the column and the email link to the column editor that I mentioned above. At the discretion of its editor, a feature column site may contain additional resources. As an example, the Chemical Information Instructor column edited by Arleen Somerville will have a periodically updated bibliography of resources for teaching and using chemical information. Due to the increase in the number of these resources available on the WWW, it only makes sense to publish this information online so that you can get to these resources with a simple click of the mouse. We expect that there will soon be additional information and resources at several other feature column sites. Following in the footsteps of the Chemical Information Instructor, up-to-date bibliographies and links to related online resources can be made available. We hope to extend the online component of our feature columns with moderated online discussion forums. If you have a suggestion for an online resource you would like to see included, let the feature editor or JCE Online (jceonline@chem.wisc.edu) know about it.

    Selamat, Ali; Omatu, Sigeru; Yanagimoto, Hidekazu; Fujinaka, Toru; Yoshioka, Michifumi

    Automatic categorization is the only viable method to deal with the scaling problem of the World Wide Web (WWW). In this paper, we propose a news web page classification method (WPCM). The WPCM uses a neural network with inputs obtained by both the principal components and class profile-based features (CPBF). Each news web page is represented by the term-weighting scheme. As the number of unique words in the collection set is big, the principal component analysis (PCA) has been used to select the most relevant features for the classification. Then the final output of the PCA is combined with the feature vectors from the class-profile which contains the most regular words in each class before feeding them to the neural networks. We have manually selected the most regular words that exist in each class and weighted them using an entropy weighting scheme. The fixed number of regular words from each class will be used as a feature vectors together with the reduced principal components from the PCA. These feature vectors are then used as the input to the neural networks for classification. The experimental evaluation demonstrates that the WPCM method provides acceptable classification accuracy with the sports news datasets.

    Many complex systems can be described as multiplex networks in which the same nodes can interact with one another in different layers, thus forming a set of interacting and co-evolving networks. Examples of such multiplex systems are social networks where people are involved in different types of relationships and interact through various forms of communication media. The ranking of nodes in multiplex networks is one of the most pressing and challenging tasks that research on complex networks is currently facing. When pairs of nodes can be connected through multiple links and in multiple layers, the ranking of nodes should necessarily reflect the importance of nodes in one layer as well as their importance in other interdependent layers. In this paper, we draw on the idea of biased random walks to define the Multiplex PageRank centrality measure in which the effects of the interplay between networks on the centrality of nodes are directly taken into account. In particular, depending on the intensity of the interaction between layers, we define the Additive, Multiplicative, Combined, and Neutral versions of Multiplex PageRank, and show how each version reflects the extent to which the importance of a node in one layer affects the importance the node can gain in another layer. We discuss these measures and apply them to an online multiplex social network. Findings indicate that taking the multiplex nature of the network into account helps uncover the emergence of rankings of nodes that differ from the rankings obtained from one single layer. Results provide support in favor of the salience of multiplex centrality measures, like Multiplex PageRank, for assessing the prominence of nodes embedded in multiple interacting networks, and for shedding a new light on structural properties that would otherwise remain undetected if each of the interacting networks were analyzed in isolation.

Examples of such multiplex systems are social networks where people are involved in different types of relationships and interact through various forms of communication media. The ranking of nodes in multiplex networks is one of the most pressing and challenging tasks that research on complex networks is currently facing. When pairs of nodes can be connected through multiple links and in multiple layers, the ranking of nodes should necessarily reflect the importance of nodes in one layer as well as their importance in other interdependent layers. In this paper, we draw on the idea of biased random walks to define the Multiplex PageRank centrality measure in which the effects of the interplay between networks on the centrality of nodes are directly taken into account. In particular, depending on the intensity of the interaction between layers, we define the Additive, Multiplicative, Combined, and Neutral versions of Multiplex PageRank, and show how each version reflects the extent to which the importance of a node in one layer affects the importance the node can gain in another layer. We discuss these measures and apply them to an online multiplex social network. Findings indicate that taking the multiplex nature of the network into account helps uncover the emergence of rankings of nodes that differ from the rankings obtained from one single layer. Results provide support in favor of the salience of multiplex centrality measures, like Multiplex PageRank, for assessing the prominence of nodes embedded in multiple interacting networks, and for shedding a new light on structural properties that would otherwise remain undetected if each of the interacting networks were analyzed in isolation.

    The World Wide Web is increasingly important for medical education. Internet served pages may also be used on a local hard disk or CD-ROM without a network or server. This allows authors to reuse existing content and provide access to users without a network connection. CD-ROM offers several advantages over network delivery of Web pages for several applications. However, creating Web pages for CD-ROM requires careful planning. Issues include file names, relative links, directory names, default pages, server created content, image maps, other file types and embedded programming. With care, it is possible to create server based pages that can be copied directly to CD-ROM. In addition, Web pages on CD-ROM may reference Internet served pages to provide the best features of both methods.

  6. Self-esteem and other-esteem in college students with borderline and avoidant personality disorder features: An experimental vignette study.

    2013-11-01

    An experimental study investigated self-esteem and other-esteem responses to either fully supportive or less supportive interpersonal feedback in college students with avoidant and borderline personality disorder features (APD and BPD respectively). Disturbances in self-esteem and in evaluations of others are central to definitions of both APD and BPD, but the extent to which such interpersonal appraisals are responsive to contextual features, such as evaluative feedback from others, is not yet clear. In theory, we would expect that individuals with pronounced PD features would show more inflexible and more negative self-evaluations and others- evaluations than those without PD features. In this study with 169 undergraduates, APD but not BPD features were associated with other-contingent state self-esteem and other-esteem. A significant interaction indicated that highly avoidant respondents felt particularly negatively about themselves and their close others in situations that conveyed subtle criticism but not in situations signalling unequivocal support. This suggests that their self-esteem and other-esteem, rather than being rigidly negative, are instead highly contingent upon interpersonal feedback. Such context contingency has implications for the trait-like description of diagnostic characteristics within current taxonomies and is in line with contemporary dynamic models of personality structure and process.

    To determine if the substance use patterns of one's close friends and romantic partners would be a significant contributor to the co-occurrence of borderline personality disorder (BPD) features and drug use problems above and beyond impulsivity and negative emotionality. Participants were 2,202 undergraduates who attended a large southeastern university between 2003 and 2006. All subjects completed measures assessing the presence of BPD symptoms, drug use problems, general personality traits, and the proportion of their friends and partners who had used illicit drugs within the past 12 months. The illicit drug use patterns of one's friends and romantic partners was a significant contributor to the co-occurrence of BPD features and drug use problems even when controlling for levels of impulsivity and negative emotionality. These findings suggest possible additional avenues for treatment focusing on helping students with BPD and drug use problems modify their social group.

    2015-01-01

    Previous studies reported that there is a significant association between attention deficit hyperactivity disorder (ADHD) in childhood and borderline personality disorder (BPD) in adulthood. The aim of this study is to investigate the relationship of borderline personality features (BPF) and ADHD symptoms while controlling the effect of childhood traumas, symptoms of depression and anxiety in adulthood on this relationship in Turkish university students. A total of 271 Turkish university students participated in this study. The students were assessed through the Turkish version of the Borderline Personality Inventory (BPI), the Adult ADHD Self-Report Scale (ASRS), the Childhood Trauma Questionnaire (CTQ-28), the Beck Depression Inventory (BDI) and the Beck Anxiety Inventory (BAI). Correlation analyses have revealed that severity of BPF is related with adult ADHD symptoms, emotional, physical abuse and depression scores. Hierarchical regression analysis has indicated that depressive symptoms, emotional and physical abuse and the severity of ADHD symptoms are the predictors for severity of BPF. Findings of the present study suggests that clinicians must carefully evaluate these variables and the relationship between them to understand BPF and ADHD symptoms in university students better. Together with depressive symptoms, emotional and physical abuse may play a mediator role on this relationship. Further studies are needed to evaluate causal relationship between these variables in both clinical and non-clinical populations.

    The Socratic method has long been a traditional teaching method in medicine and law. It is currently accepted as the standard of teaching in clinical wards, while the didactic teaching method is widely used during the first 2 years of medical school. There are arguments in support of both styles of teaching. After attending a radiology conference demonstrating different teaching methods, third-year and fourth-year medical students were invited to participate in an online anonymous survey. Of the 74 students who responded, 72% preferred to learn radiology in an active context. They preferred being given adequate time to find abnormalities on images, with feedback afterward from instructors, and they thought the best approach was a volunteer-based system of answering questions using the Socratic method in the small group. They desired to be asked questions in a way that was constructive and not belittling, to realize their knowledge deficits and to have daily pressure to come prepared. The respondents thought that pimping was an effective teaching tool, supporting previous studies. When teaching radiology, instructors should use the Socratic method to a greater extent. Combining Socratic teaching with gentle questioning by an instructor through the use of PowerPoint is a preferred method among medical students. This information is useful to improve medical education in the future, especially in radiology education. Copyright © 2011 AUR. Published by Elsevier Inc. All rights reserved.

    We up a directed network tracing links from a given integer to its divisors and analyze the properties of the Google matrix of this network. The PageRank vector of this matrix is computed numerically and it is shown that its probability is approximately inversely proportional to the PageRank index thus being similar to the Zipf law and the dependence established for the World Wide Web. The spectrum of the Google matrix of integers is characterized by a large gap and a relatively small number of nonzero eigenvalues. A simple semi-analytical expression for the PageRank of integers is derived that allows us to find this vector for matrices of billion size. This network provides a new PageRank order of integers.

    2013-12-01

    We consider a PageRank model of opinion formation on Ulam networks, generated by the intermittency map and the typical Chirikov map. The Ulam networks generated by these maps have certain similarities with such scale-free networks as the World Wide Web (WWW), showing an algebraic decay of the PageRank probability. We find that the opinion formation process on Ulam networks has certain similarities but also distinct features comparing to the WWW. We attribute these distinctions to internal differences in network structure of the Ulam and WWW networks. We also analyze the process of opinion formation in the frame of generalized Sznajd model which protects opinion of small communities.

    2016-03-30

    The link between personality and the interest of individuals for science has not been thoroughly explored. In this report, we studied psychopathological traits in students studying science in French top-ranking institutions. Three hundred and forty seven individuals answered questionnaires assessing autistic and schizotypal dimensions, as well as anxiety, depression symptomatology and attachment quality. A cluster analysis based on autistic and schizotypal traits led to the identification of 4 distinct profiles: a "low trait cluster", a "moderate autistic trait cluster", a "moderate schizotypal trait cluster" and a "high trait cluster" (HTC) composed of individuals with high scores on both autistic and schizotypal scales. Each cluster represented 20.1-27.1% of participants and was clearly different from the three others, both on autistic and on schizotypal dimensions. These groups could be also typified by their level of anxiety, depression or degraded attachment, which are proportional to the extent of psychopathological traits. Moreover, students from the HTC cluster displayed lower academic results, thus implying that autistic traits might impair success in science when they are associated with moderate schizotypal personality features. This study also suggests that depression and anxiety might mediate performance inhibition in the HTC group. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

  20. Measuring consistency of web page design and its effects on performance and satisfaction.

    Ozok, A A; Salvendy, G

    2000-04-01

    This study examines the methods for measuring the consistency levels of web pages and the effect of consistency on the performance and satisfaction of the world-wide web (WWW) user. For clarification, a home page is referred to as a single page that is the default page of a web site on the WWW. A web page refers to a single screen that indicates a specific address on the WWW. This study has tested a series of web pages that were mostly hyperlinked. Therefore, the term 'web page' has been adopted for the nomenclature while referring to the objects of which the features were tested. It was hypothesized that participants would perform better and be more satisfied using web pages that have consistent rather than inconsistent interface design; that the overall consistency level of an interface design would significantly correlate with the three elements of consistency, physical, communicational and conceptual consistency; and that physical and communicational consistencies would interact with each other. The hypotheses were tested in a four-group, between-subject design, with 10 participants in each group. The results partially support the hypothesis regarding error rate, but not regarding satisfaction and performance time. The results also support the hypothesis that each of the three elements of consistency significantly contribute to the overall consistency of a web page, and that physical and communicational consistencies interact with each other, while conceptual consistency does not interact with them.

    2017-01-01

    Answering pages from nurses about patients in need of immediate attention is one of the most difficult challenges a resident faces during their first days as a physician. A Mock Page program has been developed and adopted into a national surgical resident preparatory curriculum to prepare senior medical students for this important skill. The purpose of this study is to assess standardized mock page cases as a valid construct to assess clinical decision making and interprofessional communication skills. Mock page cases (n = 16) were administered to 213 senior medical students from 12 medical schools participating in a national surgical resident preparatory curriculum in 2013 and 2014. Clinical decision making and interprofessional communication were measured by case-specific assessments evaluating these skills which have undergone rigorous standard-setting to determine pass/fail cut points. Students' performance improved in general for both communication and clinical decision making over the 4-week course. Cases have been identified that seem to be best suited for differentiating high- from low-performing students. Chest pain, pulmonary embolus, and mental status change cases posed the greatest difficulty for student learners. Simulated mock pages demonstrate an innovative technique for training students in both effective interprofessional communication and management of common postoperative conditions they will encounter as new surgical interns.

    BACKGROUND: Practice audit is an important component of continuing professional development that may more readily be undertaken if it were less complex. This qualitative study assessed the use of personal digital assistants to facilitate data collection and review. METHODS: Personal digital assistants programmed with standard questionnaires related to upper gastrointestinal endoscopies (Practice Audit in Gastroenterology-Endoscopy [‘PAGE-Endo’]) and colonoscopies (PAGE-Colonoscopy [‘PAGE-Colo’]) were provided to Canadian gastroenterologists, surgeons and internists. Over a three-week audit period, participants recorded indications, and the expected (E) and reported (R) findings for each procedure. Thereafter, participants recorded compliance with reporting, the ease of use and value of the PAGE program, and their willingness to perform another audit. RESULTS: Over 15 to 18 months, 173 participants completed PAGE-Endo (6168 procedures) and 111 completed PAGE-Colo (4776 procedures). Most respondents noted that PAGE was easy to use (99%), beneficial (88% to 95%), and that they were willing undertake another audit (92% to 95%). In PAGE-Endo, alarm features were prevalent (55%), but major reported findings were less common than expected: esophagitis (E 29.9%, R 14.8%), esophageal stricture (E 8.3%, R 3.6%), gastric ulcer (E 17.0%, R 4.7%), gastric cancer (E 4.3%, R 1.0%) and duodenal ulcer (E 11.5%, R 5.7%). In PAGE-Colo, more colonoscopies were performed for symptom investigation (55%) than for screening (25%) or surveillance (20%). There were marked interprovincial variations with respect to sedation, biopsies and technical aspects of colonoscopy. CONCLUSION: Secure, real-time data entry with review of aggregate and individual data in the PAGE program provided an acceptable, straightforward methodology for accredited practice audit activities. PAGE has considerable potential for continuing professional development in gastroenterology and other specialties

    2016-10-01

    Recently it has been recognized that many complex social, technological and biological networks have a multilayer nature and can be described by multiplex networks. Multiplex networks are formed by a set of nodes connected by links having different connotations forming the different layers of the multiplex. Characterizing the centrality of the nodes in a multiplex network is a challenging task since the centrality of the node naturally depends on the importance associated to links of a certain type. Here we propose to assign to each node of a multiplex network a centrality called Functional Multiplex PageRank that is a function of the weights given to every different pattern of connections (multilinks) existent in the multiplex network between any two nodes. Since multilinks distinguish all the possible ways in which the links in different layers can overlap, the Functional Multiplex PageRank can describe important non-linear effects when large relevance or small relevance is assigned to multilinks with overlap. Here we apply the Functional Page Rank to the multiplex airport networks, to the neuronal network of the nematode C. elegans, and to social collaboration and citation networks between scientists. This analysis reveals important differences existing between the most central nodes of these networks, and the correlations between their so-called pattern to success.

    Full Text Available The information we need has some confusing problems such as dispersion and different organizational structure. In addition, because of the existence of unstructured data like natural language and images, extracting local content pages is extremely difficult. In the light of of the problems above, this article will apply a method combined with page structure analysis algorithm and page data extraction algorithm to accomplish the gathering of network data. In this way, the problem that traditional complex extraction model behave poorly when dealing with large-scale data is perfectly solved and the page data extraction efficiency is also boosted to a new level. In the meantime, the article will also make a comparison about pages and content of different types between the methods of DOM structure based on the page and HTML regularities of distribution. After all of those, we may find a more efficient extract method.

    The booming electronic books (e-books), as an extension to the paper book, are popular with readers. Recently, many efforts are put into the realistic page-turning simulation o f e-book to improve its reading experience. This paper presents a new 3D page-turning simulation approach, which employs piecewise time-dependent cylindrical surfaces to describe the turning page and constructs smooth transition method between time-dependent cylinders. The page-turning animation is produced by sequentially mapping the turning page into the cylinders with different radii and positions. Compared to the previous approaches, our method is able to imitate various effects efficiently and obtains more natural animation of turning page.

  4. Finding Specification Pages from the Web

    Yoshinaga, Naoki; Torisawa, Kentaro

    This paper presents a method of finding a specification page on the Web for a given object (e.g., ``Ch. d'Yquem'') and its class label (e.g., ``wine''). A specification page for an object is a Web page which gives concise attribute-value information about the object (e.g., ``county''-``Sauternes'') in well formatted structures. A simple unsupervised method using layout and symbolic decoration cues was applied to a large number of the Web pages to acquire candidate attributes for each class (e.g., ``county'' for a class ``wine''). We then filter out irrelevant words from the putative attributes through an author-aware scoring function that we called site frequency. We used the acquired attributes to select a representative specification page for a given object from the Web pages retrieved by a normal search engine. Experimental results revealed that our system greatly outperformed the normal search engine in terms of this specification retrieval.

    Full Text Available With a new titles web page, a library has a place to show faculty, students, and staff the items they are purchasing for their community. However, many times heavy programing knowledge and/or a LAMP stack (Linux, Apache, MySQL, PHP or APIs separate a library’s data from making a new titles web page a reality. Without IT staff, a new titles page can become nearly impossible or not worth the effort. Here we will demonstrate how a small liberal arts college took its acquisition data and combined it with a Google Sheet, HTML, and a little JavaScript to create a new titles web page that was dynamic and engaging to its users.

In this study, the engagement of medical students on anatomy Facebook pages was evaluated in view of their academic performance. High performers contributed to most of the engagements. They also had a particular preference for higher levels of engagement. Although the students were deeply involved in the educational element of the pages, they continued to appreciate the inherent social element. The profound engagement of the high performers indicated a consistency between Facebook use in the educational context and better student performance. At the same time, the deeper engagement of high performers refutes the opinion that Facebook use is a distractor. Instead, it supports the notion that Facebook could be a suitable platform to engage students in an educational context.

    Full Text Available Algonquian languages are famous for their animacy-based grammatical properties—an animacy based noun classification system and direct/inverse system which gives rise to animacy hierarchy effects in the determination of verb agreement. In this paper I provide new evidence for the proposal that the distinctive properties of these languages is due to the use of participant-based features, rather than spatio-temporal ones, for both nominal and verbal functional categories (Ritter & Wiltschko 2009, 2014. Building on Wiltschko (2012, I develop a formal treatment of the Blackfoot aspectual system that assumes a category Inner Aspect (cf. MacDonald 2008, Travis 1991, 2010. Focusing on lexical aspect in Blackfoot, I demonstrate that the classification of both nouns (Seinsarten and verbs (Aktionsarten is based on animacy, rather than boundedness, resulting in a strikingly different aspectual system for both categories.

  3. Flash-Aware Page Replacement Algorithm

    Directory of Open Access Journals (Sweden)

    Guangxia Xu

    2014-01-01

    Full Text Available Due to the limited main memory resource of consumer electronics equipped with NAND flash memory as storage device, an efficient page replacement algorithm called FAPRA is proposed for NAND flash memory in the light of its inherent characteristics. FAPRA introduces an efficient victim page selection scheme taking into account the benefit-to-cost ratio for evicting each victim page candidate and the combined recency and frequency value, as well as the erase count of the block to which each page belongs. Since the dirty victim page often contains clean data that exist in both the main memory and the NAND flash memory based storage device, FAPRA only writes the dirty data within the victim page back to the NAND flash memory based storage device in order to reduce the redundant write operations. We conduct a series of trace-driven simulations and experimental results show that our proposed FAPRA algorithm outperforms the state-of-the-art algorithms in terms of page hit ratio, the number of write operations, runtime, and the degree of wear leveling.

  7. Controlling misses and false alarms in a machine learning framework for predicting uniformity of printed pages

    Science.gov (United States)

    Nguyen, Minh Q.; Allebach, Jan P.

    2015-01-01

    In our previous work1 , we presented a block-based technique to analyze printed page uniformity both visually and metrically. The features learned from the models were then employed in a Support Vector Machine (SVM) framework to classify the pages into one of the two categories of acceptable and unacceptable quality. In this paper, we introduce a set of tools for machine learning in the assessment of printed page uniformity. This work is primarily targeted to the printing industry, specifically the ubiquitous laser, electrophotographic printer. We use features that are well-correlated with the rankings of expert observers to develop a novel machine learning framework that allows one to achieve the minimum "false alarm" rate, subject to a chosen "miss" rate. Surprisingly, most of the research that has been conducted on machine learning does not consider this framework. During the process of developing a new product, test engineers will print hundreds of test pages, which can be scanned and then analyzed by an autonomous algorithm. Among these pages, most may be of acceptable quality. The objective is to find the ones that are not. These will provide critically important information to systems designers, regarding issues that need to be addressed in improving the printer design. A "miss" is defined to be a page that is not of acceptable quality to an expert observer that the prediction algorithm declares to be a "pass". Misses are a serious problem, since they represent problems that will not be seen by the systems designers. On the other hand, "false alarms" correspond to pages that an expert observer would declare to be of acceptable quality, but which are flagged by the prediction algorithm as "fails". In a typical printer testing and development scenario, such pages would be examined by an expert, and found to be of acceptable quality after all. "False alarm" pages result in extra pages to be examined by expert observers, which increases labor cost. But "false

We prepare a tripartite system (say, A , B , and C ) of a given number of states and calculate information and entropy contents by assuming random states. Initially, every particle was in A (this means a black hole), and as time goes on, particles move to either B (this means Hawking radiation) or C (this means a broadly defined remnant, including a non-local transport of information, the last burst, an interior large volume, or a bubble universe, etc). If the final number of states of the remnant is smaller than that of Hawking radiation, then information will be stored by both the radiation and the mutual information between the radiation and the remnant, while the remnant itself does not contain information. On the other hand, if the final number of states of the remnant is greater than that of Hawking radiation, then the radiation contains negligible information, while the remnant and the mutual information between the radiation and the remnant contain information. Unless the number of states of the remnant is large enough compared to the entropy of the black hole, Hawking radiation must contain information; and we meet the menace of black hole complementarity again. Therefore, this contrasts the tension between various assumptions and candidates of the resolution of the information loss problem. (paper)

  9. Comparing classical and quantum PageRanks

    2017-01-01

    Following recent developments in quantum PageRanking, we present a comparative analysis of discrete-time and continuous-time quantum-walk-based PageRank algorithms. Relative to classical PageRank and to different extents, the quantum measures better highlight secondary hubs and resolve ranking degeneracy among peripheral nodes for all networks we studied in this paper. For the discrete-time case, we investigated the periodic nature of the walker's probability distribution for a wide range of networks and found that the dominant period does not grow with the size of these networks. Based on this observation, we introduce a new quantum measure using the maximum probabilities of the associated walker during the first couple of periods. This is particularly important, since it leads to a quantum PageRanking scheme that is scalable with respect to network size.

  14. Banner Pages on the New Printing Infrastructure

    CERN Multimedia

    2006-01-01

    Changes to the printing service were announced in CERN Bulletin No. 37-38/2006. In the new infrastructure, the printing of the banner page has been disabled in order to reduce paper consumption. Statistics show that the average print job size is small and the paper savings by not printing the banner page could be up to 20 %. When each printer is moved onto the new infrastructure banner page printing will be disabled. In the case of corridor printers which are shared by several users, the Helpdesk can re-enable banner page printing upon request. We hope ultimately to arrive at a situation where banner page printing is enabled on fewer than 10% of printers registered on the network. You can still print banner pages on printers where it has been centrally disabled by using Linux. Simply add it to your print job on the client side by adding the -o job-sheets option to your lpr command. Detailed documentation is available on each SLC3/4 under the following link: http://localhost:631/sum.html#4_2 Please bea...

    2016-08-01

    Full Text Available The page migration problem in Euclidean space is revisited. In this problem, online requests occur at any location to access a single page located at a server. Every request must be served, and the server has the choice to migrate from its current location to a new location in space. Each service costs the Euclidean distance between the server and request. A migration costs the distance between the former and the new server location, multiplied by the page size. We study the problem in the uniform model, in which the page has size D = 1 . All request locations are not known in advance; however, they are sequentially presented in an online fashion. We design a 2.75 -competitive online algorithm that improves the current best upper bound for the problem with the unit page size. We also provide a lower bound of 2.732 for our algorithm. It was already known that 2.5 is a lower bound for this problem.

    Full Text Available As e-commerce is gaining popularity day by day, the web has become an excellent source for gathering customer reviews / opinions by the market researchers. The number of customer reviews that a product receives is growing at very fast rate (It could be in hundreds or thousands. Customer reviews posted on the websites vary greatly in quality. The potential customer has to read necessarily all the reviews irrespective of their quality to make a decision on whether to purchase the product or not. In this paper, we make an attempt to assess are view based on its quality, to help the customer make a proper buying decision. The quality of customer review is assessed as most significant, more significant, significant and insignificant.A novel and effective web mining technique is proposed for assessing a customer review of a particular product based on the feature clustering techniques, namely, k-means method and fuzzy c-means method. This is performed in three steps : (1Identify review regions and extract reviews from it, (2 Extract and cluster the features of reviews by a clustering technique and then assign weights to the features belonging to each of the clusters (groups and (3 Assess the review by considering the feature weights and group belongingness. The k-means and fuzzy c-means clustering techniques are implemented and tested on customer reviews extracted from web pages. Performance of these techniques are analyzed.

    Full Text Available Objective – What do students need and want from library subject guides? Options such as Web 2.0 enhancement are now available to librarians creating subject-specific web pages. Librarians may be eager to implement these new tools, but are such add-ons a priority forstudents? This paper aims to start a dialogue on this issue by presenting the findings of the University of British Columbia (UBC Library’s Subject Guides Working Group (SGWG, which was tasked with assessing current library subject guides in order to make recommendations for the update and future development of UBC Library subject guides.Methods – The working group solicited feedback through a questionnaire that was distributed to undergraduate and graduate students from a variety of disciplines at UBC. The questionnaire included an evaluation of UBC subject guides, as well as guides from other academic libraries that used various platforms such as LibGuides and SubjectsPlus.Results – Respondents to the student questionnaire indicated that a simple and clean layout was of primary importance. Students also desired succinct annotations to resources and limited page scrolling. Meanwhile, few students identified Web 2.0 features such as rating systems and discussion forums as being important for their needs. The working group used the questionnaire data to create a “Top Ten” list of student recommendations.Conclusions – The “Top Ten” list of student recommendations was combined with stakeholder feedback from faculty, liaison librarians and Library Systems and Information Technology representatives to create the SGWG’s final recommendation for subject guide revision and enhancement. For the SGWG these findings called into question the necessity of Web 2.0 technologies within subject guide pages and highlighted the need for further research on the topic of subject guide usability and effectiveness.

    Using the dual mediation hypothesis, this study investigates the role of interestingness (the power of attracting or holding one's attention) attitude towards the news, in the formation of Facebook Fan Page users' electronic word-of-mouth intentions. A total of 599 Facebook fan page users in Taiwan were recruited and structural equation modeling (SEM) was used to test the research hypotheses. The results show that both perceived news entertainment and informativeness positively influence interestingness attitude towards the news. Interestingness attitude towards the news subsequently influences hedonism and utilitarianism attitudes towards the Fan Page, which then influence eWOM intentions. Interestingness attitude towards the news plays a more important role than hedonism and utilitarianism attitudes in generating electronic word-of-mouth intentions. Based on the findings, the implications and future research suggestions are provided.

  8. Page Recognition: Quantum Leap In Recognition Technology

    No milestone has proven as elusive as the always-approaching "year of the LAN," but the "year of the scanner" might claim the silver medal. Desktop scanners have been around almost as long as personal computers. And everyone thinks they are used for obvious desktop-publishing and business tasks like scanning business documents, magazine articles and other pages, and translating those words into files your computer understands. But, until now, the reality fell far short of the promise. Because it's true that scanners deliver an accurate image of the page to your computer, but the software to recognize this text has been woefully disappointing. Old optical-character recognition (OCR) software recognized such a limited range of pages as to be virtually useless to real users. (For example, one OCR vendor specified 12-point Courier font from an IBM Selectric typewriter: the same font in 10-point, or from a Diablo printer, was unrecognizable!) Computer dealers have told me the chasm between OCR expectations and reality is so broad and deep that nine out of ten prospects leave their stores in disgust when they learn the limitations. And this is a very important, very unfortunate gap. Because the promise of recognition -- what people want it to do -- carries with it tremendous improvements in our productivity and ability to get tons of written documents into our computers where we can do real work with it. The good news is that a revolutionary new development effort has led to the new technology of "page recognition," which actually does deliver the promise we've always wanted from OCR. I'm sure every reader appreciates the breakthrough represented by the laser printer and page-makeup software, a combination so powerful it created new reasons for buying a computer. A similar breakthrough is happening right now in page recognition: the Macintosh (and, I must admit, other personal computers) equipped with a moderately priced scanner and OmniPage software (from Caere

    Much has been written about the pros and cons of column-orientation as a means to speed up read-mostly analytic workloads in relational databases. In this paper we try to dissect the primitive mechanisms of a database that help express the coherence of tuples and present a novel way of organizing relational data in order to exploit the advantages of both, the row-oriented and the column-oriented world. As we go, we break with yet another bad habit of databases, namely the equal granularity of reads and writes which leads us to the introduction of consecutive clusters of disk pages called super-pages.

    Full Text Available Premise: Healthcare professionals need updated information about what is the range of "normal" variation of menstrual cycle features to support young girls and their parents in managing reproductive health, and to detect diseases early. Materials and Methods: This cross-sectional study aimed to provide an updated picture of age at menarche and main menstrual cycle characteristics and complaints in an Italian population-based sample of 3,783 adolescents attending secondary school. Girls filled in a self-administered anonymous questionnaire including questions about demography, anthropometry, smoking and drinking habits, use of contraceptive, socioeconomic status, age at menarche, menstrual pattern, and physical/psychological menstrual complaints. Mean age at menarche and prevalence of polymenorrhea (cycle length 35 days, irregularity, dysmenorrhea, and of physical/psychological complaints were computed. Factors associated with age at menarche and menstrual disturbances were explored by using multiple logistic models. Results: The girls′ mean age was 17.1 years (SD 1.4 years and the mean age at menarche was 12.4 years (SD 1.3 years; menarche occurred with two monthly peaks of frequency in July-September and in December-January (P 6 days was shown in 19.6% of girls. Gynecological age was significantly associated with cycle length (P < 0.0001 with long cycles becoming more regular within the fourth year after menarche, while frequency of polymenorrhea stabilized after the second gynecological year. Oligomenorrhea and irregularity were both significantly associated with long menstrual bleeding (adjusted OR = 2.36; 95% CI = 1.55-3.60, and adjusted OR = 2.59; 95% CI = 1.95-3.44, respectively. Conclusions: The findings of the study support the levelling-off of secular trend in menarche anticipation in Italy and confirm the timing in menstrual cycle regularization. The study provides updated epidemiological data on frequency of menstrual abnormalities

  12. Online feature selection with streaming features.

    Science.gov (United States)

    Wu, Xindong; Yu, Kui; Ding, Wei; Wang, Hao; Zhu, Xingquan

    2013-05-01

    We propose a new online feature selection framework for applications with streaming features where the knowledge of the full feature space is unknown in advance. We define streaming features as features that flow in one by one over time whereas the number of training examples remains fixed. This is in contrast with traditional online learning methods that only deal with sequentially added observations, with little attention being paid to streaming features. The critical challenges for Online Streaming Feature Selection (OSFS) include 1) the continuous growth of feature volumes over time, 2) a large feature space, possibly of unknown or infinite size, and 3) the unavailability of the entire feature set before learning starts. In the paper, we present a novel Online Streaming Feature Selection method to select strongly relevant and nonredundant features on the fly. An efficient Fast-OSFS algorithm is proposed to improve feature selection performance. The proposed algorithms are evaluated extensively on high-dimensional datasets and also with a real-world case study on impact crater detection. Experimental results demonstrate that the algorithms achieve better compactness and higher prediction accuracy than existing streaming feature selection algorithms.

    The aim of this study was to examine the potential of a self-designed Facebook page on Neuroscience, to supplement in-class teaching as a mode of blended learning. Posts were split into multiple choice questions (MCQs), general interest articles, neuroscience-related external links and resources, and lecture notes and PowerPoint presentations. The study was divided into three distinct phases: before, during, and after the Neuroscience block. Student responses were evaluated via a self-developed questionnaire. Grades achieved by students undertaking the block in 2015 and 2014 were recorded, as were the grades achieved by the same cohort in concurrent blocks in the same year of study. Results showed that ~80% of students reported that use of the page enhanced their overall subject knowledge and exam preparation. Highest page activity occurred during the Neuroscience block. Peak activity occurred directly before summative assessments, with MCQ posts having the highest impact. The cohort of students with access to the Facebook page achieved better grades in the block compared with the previous cohort, despite similar average performance in other subjects. We demonstrate the utility of Facebook as a powerful tool for undergraduate education, supplementing in-class teaching, and assisting in exam preparation, potentially increasing average student performance.

    Full Text Available From major tasks—such as recruitment of new students and staff—to the more mundane but equally important tasks—such as providing directions to campus—college and university Web sites perform a wide range of tasks for a varied assortment of users. Overlapping functions and user needs meld to create the need for a Web site with three major functions: promotion and marketing, access to online services, and providing a means of communication between individuals and groups. In turn, college and university Web sites that provide links to their library home page can be valuable assets for recruitment, public relations, and for helping users locate online services.

    2016-02-01

    Facebook has been used in health research, but there is a lack of literature regarding how Facebook may be used to recruit younger adolescents. A Facebook Page was created for an adolescent cohort study on the effects of puberty hormones on well-being and behaviour in early adolescence. Used as a communication tool with existing participants, it also aimed to alert potential participants to the study. The purpose of this paper is to provide a detailed description of the development of the study Facebook Page and present the fan response to the types of posts made on the Page using the Facebook-generated Insights data. Two types of posts were made on the study Facebook Page. The first type was study-related update posts and events. The second was relevant adolescent and family research and current news posts. Observations on the use of and response to the Page were made over 1 year across three phases (phase 1, very low Facebook use; phase 2, high Facebook use; phase 3, low Facebook use). Most Page fans were female (88.6%), with the largest group of fans aged between 35 and 44 years. Study-related update posts with photographs were the most popular. This paper provides a model on which other researchers could base Facebook communication and potential recruitment in the absence of established guidelines.

    Chin, Wei-Chien-Benny; Wen, Tzai-Hung

    2015-01-01

    A network approach, which simplifies geographic settings as a form of nodes and links, emphasizes the connectivity and relationships of spatial features. Topological networks of spatial features are used to explore geographical connectivity and structures. The PageRank algorithm, a network metric, is often used to help identify important locations where people or automobiles concentrate in the geographical literature. However, geographic considerations, including proximity and location attractiveness, are ignored in most network metrics. The objective of the present study is to propose two geographically modified PageRank algorithms-Distance-Decay PageRank (DDPR) and Geographical PageRank (GPR)-that incorporate geographic considerations into PageRank algorithms to identify the spatial concentration of human movement in a geospatial network. Our findings indicate that in both intercity and within-city settings the proposed algorithms more effectively capture the spatial locations where people reside than traditional commonly-used network metrics. In comparing location attractiveness and distance decay, we conclude that the concentration of human movement is largely determined by the distance decay. This implies that geographic proximity remains a key factor in human mobility.

    2004-01-01

    Introducing clinical staff education, along with new policies and procedures, to over 50 different clinical sites can be a challenge. As any staff educator will confess, getting people to attend an educational inservice session can be difficult. Clinical staff request training, but no one has time to attend training sessions. Putting the training along with the policies and other information into "neat" concise packages via the computer and over the company's intranet was the way to go. However, how do you bring the clinics online when some of the clinical staff may still be reluctant to turn on their computers for anything other than to gather laboratory results? Developing an easy, fun, and accessible Web page was the answer. This article outlines the development of the first training Web page at the University of Wisconsin Medical Foundation, Madison, WI.

    Full Text Available The objective of this research was to discover the behavior of museum visitors on Facebook fan page in Indonesia based on the user motivation, user expectation, online community involvement, and Facebook fan page of the museum. This research used a quantitative approach to descriptive analysis. The population was the Facebook users who had followed the Facebook fan page of the museum in Indonesia. The samples used were 270 respondents. The researchers distributed the questionnaire to a Facebook group managed by museums or communities. Based on the demographic profile of respondent, the researchers discover that the respondents are highly educated, work as employees or student, and allocate more than Rp500.000,00 per month for traveling expense. Based on social media behavior of the respondents, the respondents are active using Facebook and not aware of the presence of museum in social media. The respondents require museum information, social interaction, and entertainment on Facebook fan page of the museum. Therefore, museum managers must maintain the content quality and perceived usefulness in delivering the information through Facebook. The involvement of cultural community can help people to get honest information about museum through credible opinion from the respondents.

  16. Block models and personalized PageRank.

    Science.gov (United States)

    Kloumann, Isabel M; Ugander, Johan; Kleinberg, Jon

    2017-01-03

    Methods for ranking the importance of nodes in a network have a rich history in machine learning and across domains that analyze structured data. Recent work has evaluated these methods through the "seed set expansion problem": given a subset [Formula: see text] of nodes from a community of interest in an underlying graph, can we reliably identify the rest of the community? We start from the observation that the most widely used techniques for this problem, personalized PageRank and heat kernel methods, operate in the space of "landing probabilities" of a random walk rooted at the seed set, ranking nodes according to weighted sums of landing probabilities of different length walks. Both schemes, however, lack an a priori relationship to the seed set objective. In this work, we develop a principled framework for evaluating ranking methods by studying seed set expansion applied to the stochastic block model. We derive the optimal gradient for separating the landing probabilities of two classes in a stochastic block model and find, surprisingly, that under reasonable assumptions the gradient is asymptotically equivalent to personalized PageRank for a specific choice of the PageRank parameter [Formula: see text] that depends on the block model parameters. This connection provides a formal motivation for the success of personalized PageRank in seed set expansion and node ranking generally. We use this connection to propose more advanced techniques incorporating higher moments of landing probabilities; our advanced methods exhibit greatly improved performance, despite being simple linear classification rules, and are even competitive with belief propagation.

    2017-04-01

    Full Text Available The traditional PageRank algorithm can not efficiently perform large data Webpage scheduling problem. This paper proposes an accelerated algorithm named topK-Rank,which is based on PageRank on the MapReduce platform. It can find top k nodes efficiently for a given graph without sacrificing accuracy. In order to identify top k nodes,topK-Rank algorithm prunes unnecessary nodes and edges in each iteration to dynamically construct subgraphs,and iteratively estimates lower/upper bounds of PageRank scores through subgraphs. Theoretical analysis shows that this method guarantees result exactness. Experiments show that topK-Rank algorithm can find k nodes much faster than the existing approaches.

    Oladeji, Lasun O; Yu, Jonathan C; Oladeji, Afolayan K; Ponce, Brent A

    2015-01-01

    Medical students interested in orthopedic surgery residency positions frequently use the Internet as a modality to gather information about individual residency programs. Students often invest a painstaking amount of time and effort in determining programs that they are interested in, and the Internet is central to this process. Numerous studies have concluded that program websites are a valuable resource for residency and fellowship applicants. The purpose of the present study was to provide an update on the web pages of academic orthopedic surgery departments in the United States and to rate their utility in providing information on quality of education, faculty and resident information, environment, and applicant information. We reviewed existing websites for the 156 departments or divisions of orthopedic surgery that are currently accredited for resident education by the Accreditation Council for Graduate Medical Education. Each website was assessed for quality of information regarding quality of education, faculty and resident information, environment, and applicant information. We noted that 152 of the 156 departments (97%) had functioning websites that could be accessed. There was high variability regarding the comprehensiveness of orthopedic residency websites. Most of the orthopedic websites provided information on conference, didactics, and resident rotations. Less than 50% of programs provided information on resident call schedules, resident or faculty research and publications, resident hometowns, or resident salary. There is a lack of consistency regarding the content presented on orthopedic residency websites. As the competition for orthopedic websites continues to increase, applicants flock to the Internet to learn more about orthopedic websites in greater number. A well-constructed website has the potential to increase the caliber of students applying to a said program. Copyright © 2015 Association of Program Directors in Surgery. Published by

  9. One-Shot Decoupling and Page Curves from a Dynamical Model for Black Hole Evaporation.

    Science.gov (United States)

    Brádler, Kamil; Adami, Christoph

    2016-03-11

    One-shot decoupling is a powerful primitive in quantum information theory and was hypothesized to play a role in the black hole information paradox. We study black hole dynamics modeled by a trilinear Hamiltonian whose semiclassical limit gives rise to Hawking radiation. An explicit numerical calculation of the discretized path integral of the S matrix shows that decoupling is exact in the continuous limit, implying that quantum information is perfectly transferred from the black hole to radiation. A striking consequence of decoupling is the emergence of an output radiation entropy profile that follows Page's prediction. We argue that information transfer and the emergence of Page curves is a robust feature of any multilinear interaction Hamiltonian with a bounded spectrum.

  10. Review Pages: Cities, Energy and Built Environment

    2015-07-01

    Full Text Available Starting from the relationship between urban planning and mobility management, TeMA has gradually expanded the view of the covered topics, always remaining in the groove of rigorous scientific in-depth analysis. During the last two years a particular attention has been paid on the Smart Cities theme and on the different meanings that come with it.

    Recent developments, and especially the new and critical interest of developing countries, have helped to mark the turning of a page in the Agency's history. If the present situation in the economics of nuclear power does not change there is a danger that developing countries will lag further and further behind the advanced countries in its use. Shortage of resources impose a brake on Agency efforts to promote benefits of nuclear techniques, especially by technical assistance. These were some of the points made by Dr. Sigvard Eklund, the Director General, when he presented the Agency's annual report to the Economic and Social Council (ECOSOC) in July. (author)

  17. Web accessibility: a longitudinal study of college and university home pages in the northwestern United States.

    Science.gov (United States)

    Thompson, Terrill; Burgstahler, Sheryl; Moore, Elizabeth J

    2010-01-01

    This article reports on a follow-up assessment to Thompson et al. (Proceedings of The First International Conference on Technology-based Learning with Disability, July 19-20, Dayton, Ohio, USA; 2007. pp 127-136), in which higher education home pages were evaluated over a 5-year period on their accessibility to individuals with disabilities. The purpose of this article is to identify trends in web accessibility and long-term impact of outreach and education. Home pages from 127 higher education institutions in the Northwest were evaluated for accessibility three times over a 6-month period in 2004-2005 (Phase I), and again in 2009 (Phase II). Schools in the study were offered varying degrees of training and/or support on web accessibility during Phase I. Pages were evaluated for accessibility using a set of manual checkpoints developed by the researchers. Over the 5-year period reported in this article, significant positive gains in accessibility were revealed on some measures, but accessibility declined on other measures. The areas of improvement are arguably the more basic, easy-to-implement accessibility features, while the area of decline is keyboard accessibility, which is likely associated with the emergence of dynamic new technologies on web pages. Even on those measures where accessibility is improving, it is still strikingly low. In Phase I of the study, institutions that received extensive training and support were more likely than other institutions to show improved accessibility on the measures where institutions improved overall, but were equally or more likely than others to show a decline on measures where institutions showed an overall decline. In Phase II, there was no significant difference between institutions who had received support earlier in the study, and those who had not. Results suggest that growing numbers of higher education institutions in the Northwest are motivated to add basic accessibility features to their home pages, and that

    The PageRank is a widely used scoring function of networks in general and of the World Wide Web graph in particular. The PageRank is defined for directed graphs, but in some special cases applications for undirected graphs occur. In the literature it is widely noted that the PageRank for undirected graphs are proportional to the degrees of the vertices of the graph. We prove that statement for a particular personalization vector in the definition of the PageRank, and we also show that in gene...

    This coming Tuesday will see the unveiling of CERN's new user pages on the Web. Their simplified layout and design will make everybody's lives a whole lot easier. Stand by for Tuesday 17 April when, as announced in the Weekly Bulletin of 2 April (n°14/2001), the new newly-designed users welcome page will be hitting our screens as the default CERN home page. But don't worry, if you've got the blues for the good old blue-green home page it's still in service and, to ensure a smooth transition, will be maintained in parallel until 25 May. But in all likelihood you'll be quickly won over by the new-look pages, which are so much simpler to use. Welcome to the new Web! The aim of this revamp, led by the WPE (Web Public Education) group, is to simplify and introduce a more logical hierarchy into the menus and welcome pages on CERN's Intranet. In a second stage, the 'General Public' pages will get a similar makeover. The fact is that the number of links on the user pages, and in particular the welcome page...

    In this paper we will try to define the utility of Facebook's Personal Page marketing method. This tool that Facebook provides, is modelled and simulated using iThink in the context of a Facebook marketing agency. The paper has leveraged the system's dynamic paradigm to conduct Facebook marketing tools and methods modelling, using iThink™ system to implement them. It uses the design science research methodology for the proof of concept of the models and modelling processes. The following model has been developed for a social media marketing agent/company, Facebook platform oriented and tested in real circumstances. This model is finalized through a number of revisions and iterators of the design, development, simulation, testing and evaluation processes. The validity and usefulness of this Facebook marketing model for the day-to-day decision making are authenticated by the management of the company organization. Facebook's Personal Page method can be adjusted, depending on the situation, in order to maximize the total profit of the company which is to bring new customers, keep the interest of the old customers and deliver traffic to its website.

    1997-01-01

    This image shows features on Jupiter's moon Europa that may be 'flows' from ice volcanoes. It was taken by the Galileo spacecraft solid state imaging (CCD) system during its seventh orbit around Jupiter. North is to the top of the image. The sun illuminates the scene from the left, showing features with shapes similar to lava flows on Earth. Two such features can be seen in the northwest corner of the image. The southern feature appears to have flowed over a ridge along its western edge. Scientists use these types of relationships to determine which feature formed first. In this case, the ridge probably formed before the flow-like feature that covers it.The image, centered at 22.6 degrees north latitude and 106.7 degrees west longitude, covers an area of 180 by 215 kilometers (112 by 134 miles). The smallest distinguishable features in the image are about 1.1 kilometers (0.7 miles) across. This image was obtained on April 28, 1997, when Galileo was 27,590 kilometers (16,830 miles) from Europa.The Jet Propulsion Laboratory, Pasadena, CA manages the Galileo mission for NASA's Office of Space Science, Washington, DC. JPL is an operating division of California Institute of Technology (Caltech).This image and other images and data received from Galileo are posted on the World Wide Web, on the Galileo mission home page at URL http://galileo.jpl.nasa.gov.

    1991-04-01

    PAGE is a software package, written in BASIC language, to perform gamma spectra analysis. It was developed to be used in a high-purity intrinsic germanium detector-multichannel analyser-PC microcomputer system. The analysis program of PAGE package accomplishes functions as follows: peak location; gamma nuclides identification; activity determination. Standard nuclides sources were used to calibrate the system. To perform the efficiency x energy calibration a logarithmic fit was applied. Analysis of nuclides with overlapping peaks is allowed by PAGE program. PAGE has additional auxiliary programs for: building and list of isotopic nuclear data libraries; data acquisition from multichannel analyser; spectrum display with automatic area and FWHM determinations. This software is to be applied in analytical process control where time response is a very important parameter. PAGE takes ca. 1.5 minutes to analyse a complex spectrum from a 4096 channels MCA.

  2. An Improved Approach to the PageRank Problems

    Directory of Open Access Journals (Sweden)

    Yue Xie

    2013-01-01

    Full Text Available We introduce a partition of the web pages particularly suited to the PageRank problems in which the web link graph has a nested block structure. Based on the partition of the web pages, dangling nodes, common nodes, and general nodes, the hyperlink matrix can be reordered to be a more simple block structure. Then based on the parallel computation method, we propose an algorithm for the PageRank problems. In this algorithm, the dimension of the linear system becomes smaller, and the vector for general nodes in each block can be calculated separately in every iteration. Numerical experiments show that this approach speeds up the computation of PageRank.

  3. The rumen microbial metaproteome as revealed by SDS-PAGE.

    Science.gov (United States)

    Snelling, Timothy J; Wallace, R John

    2017-01-07

    Ruminal digestion is carried out by large numbers of bacteria, archaea, protozoa and fungi. Understanding the microbiota is important because ruminal fermentation dictates the efficiency of feed utilisation by the animal and is also responsible for major emissions of the greenhouse gas, methane. Recent metagenomic and metatranscriptomic studies have helped to elucidate many features of the composition and activity of the microbiota. The metaproteome provides complementary information to these other -omics technologies. The aim of this study was to explore the metaproteome of bovine and ovine ruminal digesta using 2D SDS-PAGE. Digesta samples were taken via ruminal fistulae and by gastric intubation, or at slaughter, and stored in glycerol at -80 °C. A protein extraction protocol was developed to maximise yield and representativeness of the protein content. The proteome of ruminal digesta taken from dairy cows fed a high concentrate diet was dominated by a few very highly expressed proteins, which were identified by LC-MS/MS to be structural proteins, such as actin and α- and β-tubulins, derived from ciliate protozoa. Removal of protozoa from digesta before extraction of proteins revealed the prokaryotic metaproteome, which was dominated by enzymes involved in glycolysis, such as glyceraldehyde-3-phosphate dehydrogenase, phosphoenolpyruvate carboxykinase, phosphoglycerate kinase and triosephosphate isomerase. The enzymes were predominantly from the Firmicutes and Bacteroidetes phyla. Enzymes from methanogenic archaea were also abundant, consistent with the importance of methane formation in the rumen. Gels from samples from dairy cows fed a high proportion of grass silage were consistently obscured by co-staining of humic compounds. Samples from beef cattle and fattening lambs receiving a predominantly concentrate diet produced clearer gels, but the pattern of spots was inconsistent between samples, making comparisons difficult. This work demonstrated for the

    2001-11-01

    The ADS Abstract Service contains over 2.3 million references in four databases: Astronomy/Astrophysics/Planetary Sciences, Instrumentation, Physics/Geophysics, and Preprints. We provide abstracts and articles free to the astronomical community for all major and many smaller astronomy journals, PhD theses, conference proceedings, and technical reports. These four databases can be queried either separately of jointly. The ADS also has scanned 1.3 million pages in 180,000 articles in the ADS Article Service. This literature archive contains all major Astronomy journals and many smaller journals, as well as conference proceedings, including the abstract books from all the LPSCs back to volume 2. A new feature gives our users the ability to see list of articles that were also read by the readers of a given article. This is a powerful tool to find out what current articles are relevant in a particular field of study. We have recently expanded the citation and reference query capabilities. It allows our users to select papers for which they want to see references or citations and then retrieve these citations/references. Another new capability is the ability to sort a list of articles by their citation count. As usual, users should be reminded that the citations in ADS are incomplete because we do not obtain reference lists from all publishers. In addition, we cannot match all references (e.g. in press, private communications, author errors, some conference papers, etc.). Anyone using the citations for analysis of publishing records should keep this in mind. More work on expanding the citation and reference features is planned over the next year.

Shortcomings were shown to be partly due to deficiencies in the Web pages themselves and partly due to students' inexperience with the medium or lack of critical evaluation skills. Future directions of this idea are discussed, including discussion of how students' reviews have been integrated into a current digital library development project.

    Purpose: The purpose is the development of a novel calibration method for dosimetry with Gafchromic EBT3 films. The method should be applicable for pretreatment verification of volumetric modulated arc, and intensity modulated radiotherapy. Because the exposed area on film can be large for such treatments, lateral scan errors must be taken into account. The correction for the lateral scan effect is obtained from the calibration data itself. Methods: In this work, the film measurements were modeled using their relative scan values (Transmittance, T). Inside the transmittance domain a linear combination and a parabolic lateral scan correction described the observed transmittance values. The linear combination model, combined a monomer transmittance state (T{sub 0}) and a polymer transmittance state (T{sub {infinity}}) of the film. The dose domain was associated with the observed effects in the transmittance domain through a rational calibration function. On the calibration film only simple static fields were applied and page sized films were used for calibration and measurements (treatment verification). Four different calibration setups were considered and compared with respect to dose estimation accuracy. The first (I) used a calibration table from 32 regions of interest (ROIs) spread on 4 calibration films, the second (II) used 16 ROIs spread on 2 calibration films, the third (III), and fourth (IV) used 8 ROIs spread on a single calibration film. The calibration tables of the setups I, II, and IV contained eight dose levels delivered to different positions on the films, while for setup III only four dose levels were applied. Validation was performed by irradiating film strips with known doses at two different time points over the course of a week. Accuracy of the dose response and the lateral effect correction was estimated using the dose difference and the root mean squared error (RMSE), respectively. Results: A calibration based on two films was the optimal

    Web proxy cache technique reduces response time by storing a copy of pages between client and server sides. If requested pages are cached in the proxy, there is no need to access the server. Due to the limited size and excessive cost of cache compared to the other storages, cache replacement algorithm is used to determine evict page when the cache is full. On the other hand, the conventional algorithms for replacement such as Least Recently Use (LRU), First in First Out (FIFO), Least Frequently Use (LFU), Randomized Policy etc. may discard important pages just before use. Furthermore, using conventional algorithm cannot be well optimized since it requires some decision to intelligently evict a page before replacement. Hence, most researchers propose an integration among intelligent classifiers and replacement algorithm to improves replacement algorithms performance. This research proposes using automated wrapper feature selection methods to choose the best subset of features that are relevant and influence classifiers prediction accuracy. The result present that using wrapper feature selection methods namely: Best First (BFS), Incremental Wrapper subset selection(IWSS)embedded NB and particle swarm optimization(PSO)reduce number of features and have a good impact on reducing computation time. Using PSO enhance NB classifier accuracy by 1.1%, 0.43% and 0.22% over using NB with all features, using BFS and using IWSS embedded NB respectively. PSO rises J48 accuracy by 0.03%, 1.91 and 0.04% over using J48 classifier with all features, using IWSS-embedded NB and using BFS respectively. While using IWSS embedded NB fastest NB and J48 classifiers much more than BFS and PSO. However, it reduces computation time of NB by 0.1383 and reduce computation time of J48 by 2.998.

  9. Toward automated assessment of health Web page quality using the DISCERN instrument.

    Science.gov (United States)

    Allam, Ahmed; Schulz, Peter J; Krauthammer, Michael

    2017-05-01

    As the Internet becomes the number one destination for obtaining health-related information, there is an increasing need to identify health Web pages that convey an accurate and current view of medical knowledge. In response, the research community has created multicriteria instruments for reliably assessing online medical information quality. One such instrument is DISCERN, which measures health Web page quality by assessing an array of features. In order to scale up use of the instrument, there is interest in automating the quality evaluation process by building machine learning (ML)-based DISCERN Web page classifiers. The paper addresses 2 key issues that are essential before constructing automated DISCERN classifiers: (1) generation of a robust DISCERN training corpus useful for training classification algorithms, and (2) assessment of the usefulness of the current DISCERN scoring schema as a metric for evaluating the performance of these algorithms. Using DISCERN, 272 Web pages discussing treatment options in breast cancer, arthritis, and depression were evaluated and rated by trained coders. First, different consensus models were compared to obtain a robust aggregated rating among the coders, suitable for a DISCERN ML training corpus. Second, a new DISCERN scoring criterion was proposed (features-based score) as an ML performance metric that is more reflective of the score distribution across different DISCERN quality criteria. First, we found that a probabilistic consensus model applied to the DISCERN instrument was robust against noise (random ratings) and superior to other approaches for building a training corpus. Second, we found that the established DISCERN scoring schema (overall score) is ill-suited to measure ML performance for automated classifiers. Use of a probabilistic consensus model is advantageous for building a training corpus for the DISCERN instrument, and use of a features-based score is an appropriate ML metric for automated DISCERN

    The development of new technologies has provided medical education with the ability to enhance the student learning experience and meet the needs of changing curricula. Students quickly adapt to using multimedia learning resources, but these need to be well designed, learner-centred and interactive for students to become significantly engaged. One way to ensure that students become committed users and that resources become distinct elements of the learning cycle is to involve students in resource design and production. Such an approach enables resources to accommodate student needs and preferences, but also provides opportunities for them to develop their own teaching and training skills. The aim of the medical student research project was to design and produce an electronic resource that was focused on a particular anatomical region. The views of other medical students were used to decide what features were suitable for inclusion and the resulting package contained basic principles and clinical relevance, and used a variety of approaches such as images of cadaveric material, living anatomy movies and quizzes. The completed package was assessed using a survey matrix and found to compare well with commercially available products. Given the ever-diversifying arena of multimedia instruction and the ability of students to be fully conversant with technology, this project demonstrates that students are ideal participants and creators of multimedia resources. It is hoped that such an approach will help to further develop the skill base of students, but will also provide an avenue of developing packages that are student user friendly, and that are focused towards particular curricula requirements. © Blackwell Publishing Ltd 2012.

My experiments show that the zebrafish, a lower vertebrate lacking cortex, supports visual feature binding of form and motion for the purpose of social behavior. These results challenge the notion that feature binding may require highly evolved neural structures and demonstrate that the nervous system of lower vertebrates can afford unexpectedly complex computations.

    2015-11-10

    PageRank is arguably the most popular ranking algorithm which is being applied in real systems ranging from information to biological and infrastructure networks. Despite its outstanding popularity and broad use in different areas of science, the relation between the algorithm's efficacy and properties of the network on which it acts has not yet been fully understood. We study here PageRank's performance on a network model supported by real data, and show that realistic temporal effects make PageRank fail in individuating the most valuable nodes for a broad range of model parameters. Results on real data are in qualitative agreement with our model-based findings. This failure of PageRank reveals that the static approach to information filtering is inappropriate for a broad class of growing systems, and suggest that time-dependent algorithms that are based on the temporal linking patterns of these systems are needed to better rank the nodes.

  19. An Adaptive Reordered Method for Computing PageRank

    Directory of Open Access Journals (Sweden)

    2013-01-01

    Full Text Available We propose an adaptive reordered method to deal with the PageRank problem. It has been shown that one can reorder the hyperlink matrix of PageRank problem to calculate a reduced system and get the full PageRank vector through forward substitutions. This method can provide a speedup for calculating the PageRank vector. We observe that in the existing reordered method, the cost of the recursively reordering procedure could offset the computational reduction brought by minimizing the dimension of linear system. With this observation, we introduce an adaptive reordered method to accelerate the total calculation, in which we terminate the reordering procedure appropriately instead of reordering to the end. Numerical experiments show the effectiveness of this adaptive reordered method.

  20. No Hawking-Page phase transition in three dimensions

    International Nuclear Information System (INIS)

    Myung, Y.S.

    2005-01-01

    We investigate whether or not the Hawking-Page phase transition is possible to occur in three dimensions. Starting with the simplest class of Lanczos-Lovelock action, thermodynamic behavior of all AdS-type black holes without charge falls into two classes: Schwarzschild-AdS black holes in even dimensions and Chern-Simons black holes in odd dimensions. The former class can provide the Hawking-Page transition between Schwarzschild-AdS black holes and thermal AdS space. On the other hand, the latter class is exceptional and thus the Hawking-Page transition is hard to occur. In three dimensions, a second-order phase transition might occur between the non-rotating BTZ black hole and the massless BTZ black hole (thermal AdS space), instead of the first-order Hawking-Page transition between the non-rotating BTZ black hole and thermal AdS space

  1. An Optimization Model for Product Placement on Product Listing Pages

    2014-01-01

    Full Text Available The design of product listing pages is a key component of Website design because it has significant influence on the sales volume on a Website. This study focuses on product placement in designing product listing pages. Product placement concerns how venders of online stores place their products over the product listing pages for maximization of profit. This problem is very similar to the offline shelf management problem. Since product information sources on a Web page are typically communicated through the text and image, visual stimuli such as color, shape, size, and spatial arrangement often have an effect on the visual attention of online shoppers and, in turn, influence their eventual purchase decisions. In view of the above, this study synthesizes the visual attention literature and theory of shelf-space allocation to develop a mathematical programming model with genetic algorithms for finding optimal solutions to the focused issue. The validity of the model is illustrated with example problems.

    Full Text Available The objective of this research has been to compare the levels of and to establish the connection between results of psychology students and their parents in relation to nationalism and cosmopolitanism and collectivism, and to horizontal and vertical individualism. In addition, an attempt has been made to define the contribution of socio-demographic variables, the importance of religion and the ideological orientation of the respondents along with collectivism/individualism in explaining the pronounced nature of nationalism and/or cosmopolitanism among the students and their parents. The research was carried out on a group of 200 students (26 male and 174 female and 296 parents (143 male and 153 female, all of Croatian nationality. Three questionnaires were applied: the Nationalism and Cosmopolitanism Scale (Čorkalo and Kamenov, 1999, the HVIC questionnaire on horizontal and vertical individualism and collectivism (Singelis et al., 1995 and a socio-demographic questionnaire. The results showed that parents of students express more marked nationalism and collectivism than their (adult children, while students express more marked cosmopolitanism and horizontal individualism than their parents. However, as far as vertical individualism is concerned, there is no difference between the average results of students and parents. The correlation between the collectivism and individualism of students and their mothers and fathers is lower than that between nationalism and cosmopolitanism. The set of socio-demographic predictors, the importance of religion, ideological orientations and collectivism/individualism more reliably foresee nationalism rather than cosmopolitanism, both in the parental and student sample. The type and contribution of the individual predictors are similar in both samples, with the exception of certain socio-demographic predictors that were shown to be significant in the parental, but not in the student sample.

    2005-12-01

    Full Text Available The tremendous growth of Web resources has made information organization and retrieval more and more difficult. As one approach to this problem, metadata schemas have been developed to characterize Web resources. However, many questions have been raised about the use of metadata schemas such as which metadata schemas have been used on the Web? How did they describe Web accessible information? What is the distribution of these metadata schemas among Web pages? Do certain schemas dominate the others? To address these issues, this study analyzed 16,383 Web pages with meta tags extracted from 200,000 OCLC sampled Web pages in 2000. It found that only 8.19% Web pages used meta tags; description tags, keyword tags, and Dublin Core tags were the only three schemas used in the Web pages. This article revealed the use of meta tags in terms of their function distribution, syntax characteristics, granularity of the Web pages, and the length distribution and word number distribution of both description and keywords tags.

    Interdisciplinary communication at a Veterans Affairs (VA) academic teaching hospital is largely dependent on alphanumeric paging, which has limitations as a result of one-way communication and lack of reliable physician identification. Adverse patient outcomes related to difficulty contacting the correct consulting provider in a timely manner have been reported. House officers were surveyed on the level of satisfaction with the current VA communication system and the rate of perceived adverse patient outcomes caused by potential delays within this system. Respondents were then asked to identify the ideal paging system. These results were used to develop and deploy a new Web site. A postimplementation survey was repeated 1 year later. This study was conducted as a quality improvement project. House officer satisfaction with the preintervention system was 3%. The majority used more than four modalities to identify consultants, with 59% stating that word of mouth was a typical source. The preferred mode of paging was the university hospital paging system, a Web-based program that is used at the partnering academic institution. Following integration of VA consulting services within the university hospital paging system, the level of satisfaction improved to 87%. Significant decreases were seen in perceived adverse patient outcomes (from 16% to 2%), delays in patient care (from 90% to 16%), and extended hospitalizations (from 46% to 4%). Our study demonstrates significant improvement in physician satisfaction with a newly implemented paging system that was associated with a decreased perceived number of adverse patient events and delays in care.

    With the advantage of the reusability property of the virtualization technology, users can reuse various types and versions of existing operating systems and drivers in a virtual machine, so as to customize their application environment. In order to prevent users' virtualization environments being impacted by driver faults in virtual machine, Chariot examines the correctness of driver's write operations by the method of combining a driver's write operation capture and a driver's private access control table. However, this method needs to keep the write permission of shadow page table as read-only, so as to capture isolated driver's write operations through page faults, which adversely affect the performance of the driver. Based on delaying setting frequently used shadow pages' write permissions to read-only, this paper proposes an algorithm using shadow page cache to improve the performance of isolated drivers and carefully study the relationship between the performance of drivers and the size of shadow page cache. Experimental results show that, through the shadow page cache, the performance of isolated drivers can be greatly improved without impacting Chariot's reliability too much.

    Full Text Available The relevance of local knowledge in cultural heritage is by now acknowledged. It helps to determine many community-based projects by identifying the material to be digitally maintained in multimedia collections provided by communities of volunteers, rather than for-profit businesses or government entities. Considering that the search and browsing of texts, images, video, and 3D models related to places is more essential than using a simple text-based search, an interactive multimedia map was implemented in this study. The map, which is loaded on a single HyperText Markup Language (HTML page using AJAX (Asynchronous JavaScript and XML, with a client-side control mechanism utilising jQuery components that are both freely available and ad-hoc developed, is updated according to user interaction. To simplify the publication of geo-referenced information, the application stores all the data in a Geographic JavaScript Object Notation (GeoJSON file rather than in a database. The multimedia contents—associated with the selected Points of Interest (PoIs—can be selected through text search and list browsing as well as by viewing their previews one by one in a sequence all together in a scrolling window (respectively: “Table”, “Folder”, and “Tile” functions. PoIs—visualised on the map with multi-shape markers using a set of unambiguous colours—can be filtered through their categories and types, accessibility status and timeline, thus improving the system usability. The map functions are illustrated using data collected in a Comenius project. Notes on the application software and architecture are also presented in this paper.

    Full Text Available Objectives – This usability study was developed to observe faculty and graduate students’ reactions to a recent redesign of the University of Kansas (KU Libraries’ website. The redesign included new navigational features, introduction of a federated search tool, a quick search box on the front page, and research subject pages. The study also provided the opportunity to observe the practices of faculty and graduate students in locating and retrieving information on the Libraries’ website.Methods – Ten participants (five faculty and five graduate students representing diverse disciplines were solicited for the study. Participants were required to access the Libraries’ website to answer a series of questions regarding new and updated features of the website. Observational analysis using Morae™ software was conducted and interviews with each participant provided details of their opinions on how these new features would influence their research and teaching activities.Results – Most of the participants either did not notice or ignored the major website changes. Links to and locations of commonly used resources (e.g. catalogue; databases; e‐journals had been changed minimally, and the faculty and graduate student participants gravitated to those familiar features to complete tasks. Prior to the study, participants had not accessed the new discovery tools; however, once previewed, responses to the tools’ utility were generally favourable. After using the federated search tool on a familiar topic, several participants noted that, when directed to databases they had not previously considered, they were able to locate citations they had missed in the past. Observers noted pitfalls in navigating the site such as inconsistent underscoring of links, ambiguous terminology, and unclear icons meant to expand subject heading lists. Unexpected searching behaviours were observed, including inconsistent and lack of conceptual understanding in

  1. Personality Features of Motorists

    Directory of Open Access Journals (Sweden)

    Andrej Justinek

    1997-12-01

    Full Text Available Justinek tries to answer the question whether or not motorists have specific personality features which predispose them for safe and well-mannered driving. A good driver should have sensory abilities which enable psycho-motor coordiation of a vehicle, intellectual and cognitive features that are important for solving problems in new, unknown situations, and emotional and motivational trails defining a driver's maturity. Justmek advocates the belief that in training future drivers greater attention should be paid to developing these features which are vital for safe driving and appropriate behaviour of drivers in traffic. He also suggests certain learning methods leading to development of the above­ mentioned personality traits. Justinek introduces the notion of the 'philosophy of driving' as an essential educational category in training future drivers.

    Given a sparse set of feature matches, we want to compute an interpolated dense displacement map. The application may be stereo disparity computation, flow computation, or non-rigid medical registration. Also estimation of missing image data, may be phrased in this framework. Since the features...... often are very sparse, the interpolation model becomes crucial. We show that a maximum likelihood estimation based on the covariance properties (Kriging) show properties more expedient than methods such as Gaussian interpolation or Tikhonov regularizations, also including scale......-selection. The computational complexities are identical. We apply the maximum likelihood interpolation to growth analysis of the mandibular bone. Here, the features used are the crest-lines of the object surface....

    1997-01-01

    The Solid State Imaging system aboard the spacecraft Galileo took this image of the surface of Europa on February 20, 1997 during its sixth orbit around Jupiter. The image is located near 16 North, 268 West; illumination is from the lower-right. The area covered is approximately 48 miles (80 kilometers) by 56 miles (95 kilometers) across. North is toward the top of the image.This image reveals that the icy surface of Europa has been disrupted by ridges and faults numerous times during its past. These ridges have themselves been disrupted by the localized formation of domes and other features that may be indicative of thermal upwelling of water from beneath the crust. These features provide strong evidence for the presence of subsurface liquid during Europa's recent past.The Jet Propulsion Laboratory, Pasadena, CA manages the mission for NASA's Office of Space Science, Washington, DC.This image and other images and data received from Galileo are posted on the World Wide Web, on the Galileo mission home page at URL http://galileo.jpl.nasa.gov.

  5. Is Domain Highlighting Actually Helpful in Identifying Phishing Web Pages?

    2017-06-01

    To evaluate the effectiveness of domain highlighting in helping users identify whether Web pages are legitimate or spurious. As a component of the URL, a domain name can be overlooked. Consequently, browsers highlight the domain name to help users identify which Web site they are visiting. Nevertheless, few studies have assessed the effectiveness of domain highlighting, and the only formal study confounded highlighting with instructions to look at the address bar. We conducted two phishing detection experiments. Experiment 1 was run online: Participants judged the legitimacy of Web pages in two phases. In Phase 1, participants were to judge the legitimacy based on any information on the Web page, whereas in Phase 2, they were to focus on the address bar. Whether the domain was highlighted was also varied. Experiment 2 was conducted similarly but with participants in a laboratory setting, which allowed tracking of fixations. Participants differentiated the legitimate and fraudulent Web pages better than chance. There was some benefit of attending to the address bar, but domain highlighting did not provide effective protection against phishing attacks. Analysis of eye-gaze fixation measures was in agreement with the task performance, but heat-map results revealed that participants' visual attention was attracted by the highlighted domains. Failure to detect many fraudulent Web pages even when the domain was highlighted implies that users lacked knowledge of Web page security cues or how to use those cues. Potential applications include development of phishing prevention training incorporating domain highlighting with other methods to help users identify phishing Web pages.

    With a perceptive eye cast on geoscience pedagogy for students labeled as disabled, Martinez-Álvarez makes important contributions to the existing conversation on placed-based learning. It is in our local backyards, from the corner basketball court, to the mud bank of a city lake, to the adjacent field where rocky outcrops spill down to a forgotten farmer's field, that we find rich working material for connecting self and community, moving students' out-of-school experiences that feature their cultural and linguistic knowledge, from misconceptions to "alternative conceptions." Informed by her insights regarding the learning of students whose literacy does not match conventional classroom practice, geoscience learning in the place of third space can act as a model of meaning making across the entire curriculum. In the pages that follow, I transact, both aesthetically and efferently, with Martinez-Álvarez's text as she presents her research on special ways of learning in placed-based geoscience explorations with bilingual children experiencing disabilities.

    2017-10-01

    Planetary science is a topic that covers an extremely diverse set of disciplines; planetary scientists are typically housed in a departments spanning a wide range of disciplines. As such it is difficult for undergraduate students to find programs that will give them a degree and research experience in our field as Department of Planetary Science is a rare sighting, indeed. Not only can this overwhelm even the most determined student, it can even be difficult for many undergraduate advisers.Because of this, the DPS Education committee decided several years ago that it should have an online resource that could help undergraduate students find graduate programs that could lead to a PhD with a focus in planetary science. It began in 2013 as a static page of information and evolved from there to a database-driven web site. Visitors can browse the entire list of programs or create a subset listing based on several filters. The site should be of use not only to undergraduates looking for programs, but also for advisers looking to help their students decide on their future plans. We present here a walk-through of the basic features as well as some usage statistics from the collected web site analytics. We ask for community feedback on additional features to make the system more usable for them. We also call upon those mentoring and advising undergraduates to use this resource, and for program admission chairs to continue to review their entry and provide us with the most up-to-date information.The URL for our site is http://dps.aas.org/education/graduate-schools.

  10. Automatic comic page image understanding based on edge segment analysis

    Science.gov (United States)

    Liu, Dong; Wang, Yongtao; Tang, Zhi; Li, Luyuan; Gao, Liangcai

    2013-12-01

    Comic page image understanding aims to analyse the layout of the comic page images by detecting the storyboards and identifying the reading order automatically. It is the key technique to produce the digital comic documents suitable for reading on mobile devices. In this paper, we propose a novel comic page image understanding method based on edge segment analysis. First, we propose an efficient edge point chaining method to extract Canny edge segments (i.e., contiguous chains of Canny edge points) from the input comic page image; second, we propose a top-down scheme to detect line segments within each obtained edge segment; third, we develop a novel method to detect the storyboards by selecting the border lines and further identify the reading order of these storyboards. The proposed method is performed on a data set consisting of 2000 comic page images from ten printed comic series. The experimental results demonstrate that the proposed method achieves satisfactory results on different comics and outperforms the existing methods.

  13. Network and User-Perceived Performance of Web Page Retrievals

    Science.gov (United States)

    Kruse, Hans; Allman, Mark; Mallasch, Paul

    1998-01-01

    The development of the HTTP protocol has been driven by the need to improve the network performance of the protocol by allowing the efficient retrieval of multiple parts of a web page without the need for multiple simultaneous TCP connections between a client and a server. We suggest that the retrieval of multiple page elements sequentially over a single TCP connection may result in a degradation of the perceived performance experienced by the user. We attempt to quantify this perceived degradation through the use of a model which combines a web retrieval simulation and an analytical model of TCP operation. Starting with the current HTTP/l.1 specification, we first suggest a client@side heuristic to improve the perceived transfer performance. We show that the perceived speed of the page retrieval can be increased without sacrificing data transfer efficiency. We then propose a new client/server extension to the HTTP/l.1 protocol to allow for the interleaving of page element retrievals. We finally address the issue of the display of advertisements on web pages, and in particular suggest a number of mechanisms which can make efficient use of IP multicast to send advertisements to a number of clients within the same network.

  14. Automatic Hidden-Web Table Interpretation by Sibling Page Comparison

    Science.gov (United States)

    Tao, Cui; Embley, David W.

    The longstanding problem of automatic table interpretation still illudes us. Its solution would not only be an aid to table processing applications such as large volume table conversion, but would also be an aid in solving related problems such as information extraction and semi-structured data management. In this paper, we offer a conceptual modeling solution for the common special case in which so-called sibling pages are available. The sibling pages we consider are pages on the hidden web, commonly generated from underlying databases. We compare them to identify and connect nonvarying components (category labels) and varying components (data values). We tested our solution using more than 2,000 tables in source pages from three different domains—car advertisements, molecular biology, and geopolitical information. Experimental results show that the system can successfully identify sibling tables, generate structure patterns, interpret tables using the generated patterns, and automatically adjust the structure patterns, if necessary, as it processes a sequence of hidden-web pages. For these activities, the system was able to achieve an overall F-measure of 94.5%.

  16. GFVO: the Genomic Feature and Variation Ontology

    KAUST Repository

    Baran, Joachim

    2015-05-05

    Falling costs in genomic laboratory experiments have led to a steady increase of genomic feature and variation data. Multiple genomic data formats exist for sharing these data, and whilst they are similar, they are addressing slightly different data viewpoints and are consequently not fully compatible with each other. The fragmentation of data format specifications makes it hard to integrate and interpret data for further analysis with information from multiple data providers. As a solution, a new ontology is presented here for annotating and representing genomic feature and variation dataset contents. The Genomic Feature and Variation Ontology (GFVO) specifically addresses genomic data as it is regularly shared using the GFF3 (incl. FASTA), GTF, GVF and VCF file formats. GFVO simplifies data integration and enables linking of genomic annotations across datasets through common semantics of genomic types and relations. Availability and implementation. The latest stable release of the ontology is available via its base URI; previous and development versions are available at the ontology’s GitHub repository: https://github.com/BioInterchange/Ontologies; versions of the ontology are indexed through BioPortal (without external class-/property-equivalences due to BioPortal release 4.10 limitations); examples and reference documentation is provided on a separate web-page: http://www.biointerchange.org/ontologies.html. GFVO version 1.0.2 is licensed under the CC0 1.0 Universal license (https://creativecommons.org/publicdomain/zero/1.0) and therefore de facto within the public domain; the ontology can be appropriated without attribution for commercial and non-commercial use.

The MRI findings of chondroblastoma including the signal intensity, the shape, the growth patterns, and the surrounding bone marrow edema and the adjacent soft tissue edema, the periosteal reaction, the adjacent joint effusion were analyzed. Results: All 20 cases demonstrated heterogeneous MR signal intensity on T 1 WI and T 2 WI images and showed lobular margins. Sixteen cases demonstrated expansive growth patterns. Surrounding bone marrow edema was found in 18 cases and adjacent soft tissue edema in 14 cases. Periosteal reaction was identified in 6 cases. In 7 cases the tumor extended to adjacent soft tissue. Adjacent joint effusion was visible on MRI in 6 cases. Conclusion: Heterogeneous signal intensity, lobular margins and expansive growth pattern, adjacent bone marrow and soft tissue edema were the common features of chondroblastoma on MRI. (authors)

    Thalassemia is a kind of chronic, inherited, microcytic anemia characterized by defective hemoglobin synthesis and ineffective erythropoiesis. In all thalassemias clinical features that result from anemia, transfusional, and absorptive iron overload are similar but vary in severity. The radiographic features of {beta}-thalassemia are due in large part to marrow hyperplasia. Markedly expanded marrow space lead to various skeletal manifestations including spine, skull, facial bones, and ribs. Extramedullary hematopoiesis (ExmH), hemosiderosis, and cholelithiasis are among the non-skeletal manifestations of thalassemia. The skeletal X-ray findings show characteristics of chronic overactivity of the marrow. In this article both skeletal and non-skeletal manifestations of thalassemia are discussed with an overview of X-ray findings, including MRI and CT findings. (orig.)

    Full Text Available We introduce a toolkit for working with the 13.6 million volume Extracted Features Dataset from the HathiTrust Research Center. You will learn how to peer at the words and trends of any book in the collection, while developing broadly useful Python data analysis skills. The HathiTrust holds nearly 15 million digitized volumes from libraries around the world. In addition to their individual value, these works in aggregate are extremely valuable for historians. Spanning many centuries and genres, they offer a way to learn about large-scale trends in history and culture, as well as evidence for changes in language or even the structure of the book. To simplify access to this collection the HathiTrust Research Center (HTRC has released the Extracted Features dataset (Capitanu et al. 2015: a dataset that provides quantitative information describing every page of every volume in the collection. In this lesson, we introduce the HTRC Feature Reader, a library for working with the HTRC Extracted Features dataset using the Python programming language. The HTRC Feature Reader is structured to support work using popular data science libraries, particularly Pandas. Pandas provides simple structures for holding data and powerful ways to interact with it. The HTRC Feature Reader uses these data structures, so learning how to use it will also cover general data analysis skills in Python.

    Full Text Available Nowadays, Web spam pages are a critical challenge for Web retrieval systems which have drastic influence on the performance of such systems. Although these systems try to combat the impact of spam pages on their final results list, spammers increasingly use more sophisticated techniques to increase the number of views for their intended pages in order to have more commercial success. This paper employs the recently proposed Layered Multi-population Genetic Programming model for Web spam detection task as well application of correlation coefficient analysis for feature space reduction. Based on our tentative results, the designed classifier, which is based on a combination of easy to compute features, has a very reasonable performance in comparison with similar methods.

  6. Creating a Facebook Page for the Seismological Society of America

    Newman, S. B.

    2009-12-01

    In August, 2009 I created a Facebook “fan” page for the Seismological Society of America. We had been exploring cost-effective options for providing forums for two-way communication for some months. We knew that a number of larger technical societies had invested significant sums of money to create customized social networking sites but that a small society would need to use existing low-cost software options. The first thing I discovered when I began to set up the fan page was that an unofficial SSA Facebook group already existed, established by Steven J. Gibbons, a member in Norway. Steven had done an excellent job of posting material about SSA. Partly because of the existing group, the official SSA fan page gained fans rapidly. We began by posting information about our own activities and then added links to activities in the broader geoscience community. While much of this material also appeared on our website and in our publication, Seismological Research Letters (SRL), the tone on the FB page is different. It is less formal with more emphasis on photos and links to other sites, including our own. Fans who are active on FB see the posts as part of their social network and do not need to take the initiative to go to the SSA site. Although the goal was to provide a forum for two-way communication, our initial experience was that people were clearly reading the page but not contributing content. This appears to be case with fan pages of sister geoscience societies. FB offers some demographic information to fan site administrators. In an initial review of the demographics it appeared that fans were younger than the overall demographics of the Society. It appeared that a few of the fans are not members or even scientists. Open questions are: what content will be most useful to fans? How will the existence of the page benefit the membership as a whole? Will the page ultimately encourage two-way communication as hoped? Web 2.0 is generating a series of new

    This paper describes and evaluates the public health web pages classification model based on key phrase extraction and matching. Easily extendible both in terms of new classes as well as the new language this method proves to be a good solution for text classification faced with the total lack of training data. To evaluate the proposed solution we have used a small collection of public health related web pages created by a double blind manual classification. Our experiments have shown that by choosing the adequate threshold value the desired value for either precision or recall can be achieved.

    Malicious web pages are an increasing threat to current computer systems in recent years. Traditional anti-virus techniques focus typically on detection of the static signatures of Malware and are ineffective against these new threats because they cannot deal with zero-day attacks. In this paper, a novel classification method for detecting malicious web pages is presented. This method is generalization and specialization of attack pattern based on inductive learning, which can be used for updating and expanding knowledge database. The attack pattern is established from an example and generalized by inductive learning, which can be used to detect unknown attacks whose behavior is similar to the example.

  12. Various Landscapes and Features on Europa

    Science.gov (United States)

    1997-01-01

    These 15 frames show the great variety of surface features on Jupiter's icy moon, Europa, which have been revealed by the Galileo spacecraft Solid State Imaging (CCD) system during its first six orbits around Jupiter from June 1996 to February 1997. North is to the top of each of the images. The features seen on Europa's surface document both internal and external processes shaping the icy crust. Internal processes and the possible presence of liquid water beneath the ice are indicated by features such as 'dark spots', lobe-shaped flow features, 'puddles','mottled terrain', knobs, pits, and the darker areas along ridges and triple bands.Europa is subjected to constant tugging from the giant planet, Jupiter, as well as from its neighboring moons, Io and Ganymede. This causes 'tidal' forces that affect Europa's interior and surface. Evidence for such forces includes ridges, fractures, wedge-shaped bands, and areas of 'chaos'. Some of these features result from alternate extension and compression buckling and pulling apart Europa's icy shell.Impact craters document external effects on a planet's surface. Although present on Europa, impact craters are relatively scarce compared to the number seen on Ganymede, Callisto, and on the surfaces of most other 'rocky' planets and moons in our solar system. This scarcity of craters suggests that the surface of Europa is very young. 'Maculae' on Europa may be the scars from large impact events.These images have resolutions from 27 meters (89 feet) to 7 kilometers (4.3 miles) per picture element (pixel) and were taken by Galileo at ranges of 2,500 kilometers (1,525 miles) to 677,000 kilometers (413,000 miles) from Europa.The Jet Propulsion Laboratory, Pasadena, CA manages the Galileo mission for NASA's Office of Space Science, Washington, DC.

    Vasculitis is defined as an inflammatory process involving blood vessels, and can lead to destruction of the vascular wall and ischemic damage to the organs supplied by these vessels. The lung is commonly affected. A number of attempts have been made to classify and organize pulmonary vasculitis, but because the clinical manifestations and pathologic features of the condition overlap considerably, these afforts have failed to achieve a consensus. We classified pulmonary vasculitis as belonging to either the angitiis-granulomatosis group, the diffuse pulmonary hemorrhage with capillaritis group, or 'other'. Characteristic radiographic and CT findings of the different types of pulmonary vasculitis are illustrated, with a brief discussion of the respective disease entities

    Onychomatricoma is a rare tumour of the nail matrix with peculiar clinical and histological features and electron microscopic findings. We report on 5 cases with appearances which were misleading. Three presented as longitudinal melanonychia, a previously unreported observation. One case had the appearance of a cutaneous horn. In 3 of the 5 cases the tumour was associated with an onychomycosis and this may thus have been a predisposing factor in the secondary fungal infestation. Onychomatricoma appears as a multi-faceted tumour which can be mimicked by longitudinal melanonychia and/or onychomycosis.

    Tao, Xin; Tang, Zhi; Xu, Canhui

    2013-12-01

    In this paper, a model is proposed to learn logical structure of fixed-layout document pages by combining support vector machine (SVM) and conditional random fields (CRF). Features related to each logical label and their dependencies are extracted from various original Portable Document Format (PDF) attributes. Both local evidence and contextual dependencies are integrated in the proposed model so as to achieve better logical labeling performance. With the merits of SVM as local discriminative classifier and CRF modeling contextual correlations of adjacent fragments, it is capable of resolving the ambiguities of semantic labels. The experimental results show that CRF based models with both tree and chain graph structures outperform the SVM model with an increase of macro-averaged F1 by about 10%.

    1985-03-01

    An automatic evolutionary search is applied to the problem of feature extraction in an OCR application. A performance measure based on feature independence is used to generate features which do not appear to suffer from peaking effects [17]. Features are extracted from a training set of 30 600 machine printed 34 class alphanumeric characters derived from British mail. Classification results on the training set and a test set of 10 200 characters are reported for an increasing number of features. A 1.01 percent forced decision error rate is obtained on the test data using 316 features. The hardware implementation should be cheap and fast to operate. The performance compares favorably with current low cost OCR page readers.

    Video object tracking is widely used in many real-world applications, and it has been extensively studied for over two decades. However, tracking robustness is still an issue in most existing methods, due to the difficulties with adaptation to environmental or target changes. In order to improve adaptability, this paper formulates the tracking process as a ranking problem, and the PageRank algorithm, which is a well-known webpage ranking algorithm used by Google, is applied. Labeled and unlabeled samples in tracking application are analogous to query webpages and the webpages to be ranked, respectively. Therefore, determining the target is equivalent to finding the unlabeled sample that is the most associated with existing labeled set. We modify the conventional PageRank algorithm in three aspects for tracking application, including graph construction, PageRank vector acquisition and target filtering. Our simulations with the use of various challenging public-domain video sequences reveal that the proposed PageRank tracker outperforms mean-shift tracker, co-tracker, semiboosting and beyond semiboosting trackers in terms of accuracy, robustness and stability.

    2018-01-01

    Research in human vision suggests that in a single fixation, humans can extract a significant amount of information from a natural scene, e.g. the semantic category, spatial layout, and object identities. This ability is useful, for example, for quickly determining location, navigating around obstacles, detecting threats, and guiding eye movements to gather more information. In this paper, we ask a new question: What can we see at a glance at a web page - an artificial yet complex "real world" stimulus? Is it possible to notice the type of website, or where the relevant elements are, with only a glimpse? We find that observers, fixating at the center of a web page shown for only 120 milliseconds, are well above chance at classifying the page into one of ten categories. Furthermore, this ability is supported in part by text that they can read at a glance. Users can also understand the spatial layout well enough to reliably localize the menu bar and to detect ads, even though the latter are often camouflaged among other graphical elements. We discuss the parallels between web page gist and scene gist, and the implications of our findings for both vision science and human-computer interaction.

    Kootsey, J Mailen; Siriphongs, Daniel; McAuley, Grant

    2004-01-01

    A new Web software architecture, NumberLinX (NLX), has been integrated into a commercial Web design program to produce a drag-and-drop environment for building interactive simulations. NLX is a library of reusable objects written in Java, including input, output, calculation, and control objects. The NLX objects were added to the palette of available objects in the Web design program to be selected and dropped on a page. Inserting an object in a Web page is accomplished by adding a template block of HTML code to the page file. HTML parameters in the block must be set to user-supplied values, so the HTML code is generated dynamically, based on user entries in a popup form. Implementing the object inspector for each object permits the user to edit object attributes in a form window. Except for model definition, the combination of the NLX architecture and the Web design program permits construction of interactive simulation pages without writing or inspecting code.

    To investigate the impact of associating classroom learning of medical physiology with a Facebook group page in an all-women medical college of a conservative small city in Pakistan. Qualitative interpretivist study using semi-structured interviews. Women Medical College Abbottabad, Pakistan, from March to December 2014. Aclosed Facebook study group was established at a local medical college in Pakistan. It was used to upload learning resources and initiate discussions, coordinated with classroom lectures of physiology. Thirteen semistructured interviews were conducted with volunteer students according to a standard protocol. Five major themes were identified. Facebook group is something new and exciting; it motivated self-study, research, collaborative learning and improved class attendance. Convenience of easily accessible resources allowed the students to concentrate on the lecture rather than note taking. It was easier to communicate with the instructor through Facebook than face to face. Lurkers were also learning. High achievers who had adapted to the current didactic system of teaching were less receptive of the collaborative learning and favored teaching geared towards exam preparation. Using social media for e-learning in undergraduate medical education can enhance the student learning experience, especially in resource-limited regions where Information and communication technology is not an integrated part of the teaching process.

    Markarian, Maria F.; Villarroel, Gonzalo M.; Nagel, Jorge R.

    2003-01-01

    Purpose: Mobius Syndrome or congenital facial diplegia is associated with paralysis of the lateral gaze movements. This syndrome may include other cranial nerve palsies and be associated to musculoskeletal anomalies. Our objective is to show the MRI findings in Mobius Syndrome. Material and methods: MRI study was performed in 3 patients with clinic diagnosis of Mobius Syndrome. RMI (1.5T); exams included axial FSE (T1 and T2), FLAIR, SE/EPI, GRE/20, sagittal FSE T2 , coronal T1, diffusion, angio MRI and Spectroscopy sequences. Results: The common features of this syndrome found in MRI were: depression or straightening of the floor of the fourth ventricle, brainstem anteroposterior diameter diminution, morphologic alteration of the pons and medulla oblongata and of the hypoglossal nuclei as well as severe micrognathia. Conclusion: The morphologic alterations of Mobius Syndrome can be clearly identified by MRI; this method has proved to be a useful diagnostic examination. (author)

    The clinical features often patients with odontogenic keratocysts were studied. One patient had Gorlin-GoJtz syndrome. A total of fourteen radiolucent lesions were observed on radiographic examination. All the fourteen lesions were diagnosed as odontogenic keratocyst after histopathclogical examination of biopsied tissue from the patients. The age at diagnosis ranged from 25-72 years with a mean age of 37.6 years. The male : female ratio was 2.3:1. Thirteen of these lesions occurred in the mandible, nine involved the mandibular third molar region. Involvement of the ramus of the mandible produced a sausage-shaped radiolucency. Cystic lesions which have been present for long periods of time showed scalloped margins, due to the regional resorption of the surrounding bone. The bony ledges present on the cortical bones simulated multilocular appearance in such cases. It was also observed that the lesions in older individuals perforated the cortical plates rather than eliciting a periostally induced bony expansion. (author)

    To document the proctographic features of anismus at evacuation proctography and determine the optimum radiologic measurements for diagnosis. Twenty-four patients with anismus according to clinical and multiple physiologic criteria were examined with evacuation proctography. Structural and functional measurements were compared with those of a group of 20 asymptomatic subjects. No significant difference between patients and control subjects was found with respect to pelvic descent, rectocele, or any anorectal angle measurement. In patients with anismus, initiation of evacuation was prolonged (median, 9 vs 3 seconds for control subjects; P anismus should be abandoned. Patients with anismus demonstrate delayed initiation of evacuation, which is also prolonged and incomplete. Incomplete evacuation after 30 seconds is highly suggestive of anismus.

  5. Multispectral Image Feature Points

    2012-09-01

    Full Text Available This paper presents a novel feature point descriptor for the multispectral image case: Far-Infrared and Visible Spectrum images. It allows matching interest points on images of the same scene but acquired in different spectral bands. Initially, points of interest are detected on both images through a SIFT-like based scale space representation. Then, these points are characterized using an Edge Oriented Histogram (EOH descriptor. Finally, points of interest from multispectral images are matched by finding nearest couples using the information from the descriptor. The provided experimental results and comparisons with similar methods show both the validity of the proposed approach as well as the improvements it offers with respect to the current state-of-the-art.

    Changes in our political infrastructure, the continuing frailties of our economy, and a stark growth in population, have greatly impacted upon the perceived stability of the NHS. Healthcare teams have had to adapt to these changes, and so too have the technologies upon which they rely to deliver first-class patient care. Here Sarah Hunt, marketing co-ordinator at Aid Call, assesses how the changing healthcare environment has affected one of its fundamental technologies - the nurse call system, argues the case for wireless such systems in terms of what the company claims is greater adaptability to changing needs, and considers the ever-wider range of features and functions available from today's nurse call equipment, particularly via connectivity with both mobile devices, and ancillaries ranging from enuresis sensors to staff attack alert 'badges'.

We will illustrate CT findings that can help in the diagnosis of abdominal tuberculosis and describe imaging features that differentiate it from other inflammatory and neoplastic diseases, particularly lymphoma and Crohn's disease. As tuberculosis can affect any organ in the abdomen, emphasis is placed to ileocecal involvement, lymphadenopathy, peritonitis and solid organ disease (liver, spleen and pancreas). A positive culture or hystologic analysis of biopsy is still required in many patients for definitive diagnosis. Learning objectives:1.To review the relevant pathophysiology of abdominal tuberculosis. 2.Illustrate CT findings that can help in the diagnosis.

    The SDO instruments (EVE, AIA and HMI) teams have created a digital comic book series for upper elementary and middle school students featuring solar science aficionados Camilla and Colours, 2 cool mascot characters. These comics may be printed or read on mobile devices and are available as a free download. Many teachers are looking for resources to use with their students via the IPad so our collaboration helps supply teachers with a great resource that teaches about solar concepts and helps dispel solar misconceptions. It doesn't come as a surprise to a lot of us, but a recent study confirms what's been theorized for years: Comics are a stronger learning tool than text books. Image-based storytelling is a powerful educational tool. Comics are probably more able to combine story and information simultaneously, more effectively and seamlessly, than almost any other medium. There's also a great potential to incorporate interactive elements into digital versions, so that more information can be presented on certain items on a page. For example, videos, animations and even historic footage and audio can be embedded into digital comics. Really, the possibilities are limited only by the creators' imaginations as to how to find new ways to create a rich experience that is interesting to explore for students. We are excited to unveil this new series of solar science comics that promotes science literacy with upper elementary and middle school students.

    The Facilities Engineering and Architectural Branch is responsible for the design and maintenance of buildings, laboratories, and civil structures. In order to improve efficiency and quality, the FEAB has dedicated itself to establishing a data infrastructure based on Geographic Information Systems, GIS. The value of GIS was explained in an article dating back to 1980 entitled "Need for a Multipurpose Cadastre" which stated, "There is a critical need for a better land-information system in the United States to improve land-conveyance procedures, furnish a basis for equitable taxation, and provide much-needed information for resource management and environmental planning." Scientists and engineers both point to GIS as the solution. What is GIS? According to most text books, Geographic Information Systems is a class of software that stores, manages, and analyzes mapable features on, above, or below the surface of the earth. GIS software is basically database management software to the management of spatial data and information. Simply put, Geographic Information Systems manage, analyze, chart, graph, and map spatial information. GIS can be broken down into two main categories, urban GIS and natural resource GIS. Further still, natural resource GIS can be broken down into six sub-categories, agriculture, forestry, wildlife, catchment management, archaeology, and geology/mining. Agriculture GIS has several applications, such as agricultural capability analysis, land conservation, market analysis, or whole farming planning. Forestry GIs can be used for timber assessment and management, harvest scheduling and planning, environmental impact assessment, and pest management. GIS when used in wildlife applications enables the user to assess and manage habitats, identify and track endangered and rare species, and monitor impact assessment.

    To use Facebook to facilitate online discussion of the content of a Comprehensive Disease Management course and to evaluate student use and perceptions of this exercise. A Facebook page was created and coordinators encouraged students to "like" the page and to post and view study tips, links, or questions. At the end of the course, students' use and perceptions were evaluated using an anonymous survey tool. At the end of week 1, there were 81 followers, 5 wall posts, and 474 visits to the course Facebook page. At peak use, the page had 117 followers, 18 wall posts, and 1,326 visits. One hundred nineteen students (97% of the class) completed the survey tool. Twenty-six percent of students contributed posts compared to 11% who posted on the course discussion board on Blackboard. Students were more likely to post and be exposed to posts on Facebook than on Blackboard. Students found Facebook helpful and 57% said they would miss Facebook if use was not continued in subsequent courses. Students in a Comprehensive Disease Management course found the addition of a Facebook page a valuable study tool and thought most posts added to their learning.

  14. Dependency Parsing with Transformed Feature

    Directory of Open Access Journals (Sweden)

    Fuxiang Wu

    2017-01-01

    Full Text Available Dependency parsing is an important subtask of natural language processing. In this paper, we propose an embedding feature transforming method for graph-based parsing, transform-based parsing, which directly utilizes the inner similarity of the features to extract information from all feature strings including the un-indexed strings and alleviate the feature sparse problem. The model transforms the extracted features to transformed features via applying a feature weight matrix, which consists of similarities between the feature strings. Since the matrix is usually rank-deficient because of similar feature strings, it would influence the strength of constraints. However, it is proven that the duplicate transformed features do not degrade the optimization algorithm: the margin infused relaxed algorithm. Moreover, this problem can be alleviated by reducing the number of the nearest transformed features of a feature. In addition, to further improve the parsing accuracy, a fusion parser is introduced to integrate transformed and original features. Our experiments verify that both transform-based and fusion parser improve the parsing accuracy compared to the corresponding feature-based parser.

    Using a feature data model, geographic phenomena can be represented effectively by integrating space, theme, and time. This paper extends and implements a feature data model that supports query and visualization of geographic features using their non-spatial and temporal relationships. A prototype feature-oriented geographic information system (FOGIS) is then developed and storage of features named Feature Database is designed. Buildings from the U.S. Marine Corps Base, Camp Lejeune, North Carolina and subways in Chicago, Illinois are used to test the developed system. The results of the applications show the strength of the feature data model and the developed system 'FOGIS' when they utilize non-spatial and temporal relationships in order to retrieve and visualize individual features.

At the outset, I was given goals and expectations from my branch and from my mentor with regards to the further implementation of GIs. Those goals are as follows: (1) Continue the development of GIS for the underground structures. (2) Extract and export annotated data from AutoCAD drawing files and construct a database (to serve as a prototype for future work). (3) Examine existing underground record drawings to determine existing and non-existing underground tanks. Once this data was collected and analyzed, I set out on the task of creating a user-friendly database that could be assessed by all members of the branch. It was important that the database be built using programs that most employees already possess, ruling out most AutoCAD-based viewers. Therefore, I set out to create an Access database that translated onto the web using Internet

    Margrethe Basse, Ellen

    2010-03-01

    'Retrospective views on our planet's future' - This was the theme of a tandem of meetings held by Past Global Changes (PAGES; http://www.pages-igbp.org), a project of the International Geosphere-Biosphere Programme (IGBP). It reflects the philosophy of PAGES and its community of scientists that the past holds the key to better projections of the future. Climatic and environmental evidence from the past can be used to sharpen future projections of global change, thereby informing political and societal decisions on mitigation and adaptation. Young scientists are critical to the future of this endeavour, which we call 'paleoscience'. Their scientific knowledge, interdisciplinarity, international collaboration, and leadership skills will be required if this field is to continue to thrive. Meanwhile, it is also important to remember that science develops not only by applying new strategies and new tools to make new observations, but also by building upon existing knowledge. Modern research in paleoscience began around fifty years ago, and one could say that the third generation of researchers is now emerging. It is a wise investment to ensure that existing skills and knowledge are transferred to this generation. This will enable them to lead the science towards new accomplishments, and to make important contributions towards the wider field of global change science. Motivated by such considerations, PAGES organized its first Young Scientists Meeting (YSM), held in Corvallis (Oregon, USA) in July 2009 (http://www.pages-osm.org/ysm/index.html). The meeting took place immediately before the much larger 3rd PAGES Open Science Meeting (OSM; http://www.pages-osm.org/osm/index.html). The YSM brought together 91 early-career scientists from 21 different nations. During the two-day meeting, PhD students, postdoctoral researchers, and new faculty met to present their work and build networks across geographical and disciplinary borders.

    Rhabdomyolysis is a potentially life threatening condition of various etiology. The association between rhabdomyolysis and muscular dystrophies is under-recognized in clinical practice. To identify muscular dystrophies presenting with rhabdomyolysis at onset or as predominant feature. We retrospectively reviewed clinical and laboratory data of patients with a genetically confirmed muscular dystrophy in whom rhabdomyolysis was the presenting or main clinical manifestation. Thirteen unrelated patients (males=6; females=7) were identified. Median age at time of rhabdomyolysis was 18 years (range, 2-47) and median duration between the first episode of rhabdomyolysis and molecular diagnosis was 2 years. Fukutin-related protein (FKRP) muscular dystrophy (n=6) was the most common diagnosis, followed by anoctaminopathy-5 (n=3), calpainopathy-3 (n=2) and dystrophinopathy (n=2). Four patients experienced recurrent rhabdomyolysis. Eight patients were asymptomatic and 3 reported myalgia and exercise intolerance prior to the rhabdomyolysis. Exercise (n=6) and fever (n=4) were common triggers; rhabdomyolysis was unprovoked in 3 patients. Twelve patients required hospitalization. Baseline CK levels were elevated in all patients (median 1200 IU/L; range, 600-3600). Muscular dystrophies can present with rhabdomyolysis; FKRP mutations are particularly frequent in causing such complication. A persistently elevated CK level in patients with rhabdomyolysis warrants consideration for underlying muscular dystrophy. Copyright © 2015 Elsevier B.V. All rights reserved.
