Weblog Search Engine Based on Quality Criteria
F. Azimzadeh,,A. R. Ramli,,B. M. Ali, H. Ibrahim,B. M. Ali
International Journal on Computer Science and Engineering , 2011,
Abstract: Nowadays, increasing amount of human knowledge is placed in computerized repositories such as the World Wide Web. This gives rise to the problem of how to locate specific pieces of information in these often quite unstructured repositories. Search engines is the best solved. Some studied show that, almost half of the traffic to the blog server comes from search engines. The more outgoing and informal social nature of the blogosphere opens the opportunity for exploiting more socially-oriented features. The nature of blogs, which are usually characterized by their personal and informal nature, dynamically and constructed on the new relational links required new quality measurement for blog search engine. Link analysis algorithms that exploit the Web graph may not work well in the blogosphere in general. (Gon alves et al 2010) indicated that most of the popular blogs in the dataset (70%) have a PageRank value equal -1, being thus almost invisible to the search engine. We expected that incorporated the special blogs quality criteria would be more desirably retrieved by search engines.
Quality Issues in Higher Education: A Multicriteria Framework of Satisfaction Measures  [PDF]
G. A. Dimas, A Goula, G. Pierrakos
Creative Education (CE) , 2011, DOI: 10.4236/ce.2011.23042
Abstract: Higher education attributes significant interest to student satisfaction because of its potential impact on the quality dimensions of the offered services. This is illustrated from the large number of studies that have shown a moderate to strong relationship between these two concepts. This paper provides a detailed analysis of a student satisfaction survey conducted at the Health Care Management Department of the Technological Education Institute of Athens. The analysis was based on a multi-criteria preference disaggregation method (MUSA). Results are focused on the evaluation of student choices, while significant findings of the applied methodology constitute the determination of strong and weak points of the educational component’s preferences that form important suggestions for the improvement of the satisfaction level and the quality characteristics of the correspondent services.
An Analysis of Ambient Air Quality Conditions Over Delhi, India From 2004 to 2009  [PDF]

Atmospheric and Climate Sciences (ACS) , 2011, DOI: 10.4236/acs.2011.14024
Abstract: We analyzed 1-hour, 8-hour and 24-hour averaged criteria pollutants (NO2, SO2, CO, PM22.5, and PM10) during 2004 - 2009 at three observational sites i.e. Income Tax Office (ITO), Sirifort and Delhi College of Engineering (DCE) in Delhi, India. The analysis reveals increased pollutant concentrations at the urban ITO site as compared to the other two sites, suggesting the need to better locate hot spots in designing the monitoring network. There is also significant year to year variation in the design value trends of criteria pollutants at these three sites, which may be attributed to meteorological variations and local-level emission fluctuations. Correlations among criteria pollutants vary annually and spatially from site to site, indicating the heterogeneous nature of air mix. The annual ratios of CO/NOx are considerably higher than SO2/NOx confirming that vehicular source emissions are the primary contributors to air pollution in Delhi. The seasonal analysis of criteria pollutants reveals relatively higher concentrations in winter because of limited pollutant dispersion and lower concentrations during the monsoon period (rainy season). The diurnal averages of criteria pollutants reveal that vehicular emissions strongly influence temporal variations of these pollutants. Weekdays and weekend diurnal averages do not show noticeable differences.

Journal of Software Engineering and Applications (JSEA) , 2013, DOI: 10.4236/jsea.2013.611071

The objective of this study is to compare the ranking of the quality of e-commerce B2C portals in Brazil according to explicit criteria described in the article with the ranking according to the INFO 100 ranking. Theoretical research is first described, followed by the construction of eight self-established criteria of B2C portal quality measures and identification and compilation of requirements used by the I-Best, Opinia, E-bit and other institutes. After that, a portal quality evaluation is made by the web site content analysis; finally, a comparison of the rankings is presented. The obtained results showed that in spite of the lack of knowledge of the criteria adopted by INFO100 [1], there could be agreement with the criteria adopted in this study, because there was agreement with the results for the Ponto Frio portal. Therefore, it was concluded that the eight criteria used in this study can be useful in a quality analysis of B2C electronic portals.

Improving Ordering Practices and Radiology Workflow in the Emergency Department through Multidisciplinary Didactic Series: Survey Based Evaluation  [PDF]

Open Journal of Radiology (OJRad) , 2014, DOI: 10.4236/ojrad.2014.42019

The purpose of our Quality Improvement (QI) project was to evaluate the effectiveness of radiology-led didactics on efficiency and ordering practices in the emergency department. Residents of the emergency medicine (EM) program at Downstate Medical Center/Kings County Hospital (postgraduate years 1 - 4) participated in a didactic lecture series during the first two months of the 2013 academic year. Two fifteen-minute lectures with a question and answer session were designed to focus on radiation risk, American College of Radiology (ACR) appropriateness criteria and the department of radiology’s policies. A short survey questionnaire that included questions on ACR appropriateness criteria, radiology experiences and opinions/attitudes regarding radiology was distributed and analyzed before and after the didactic series. The average score for the knowledge-based technical questions on ACR appropriateness criteria was 60.5% initially and 76.4% post-lecture with an overall improvement of 25%, which was statistically significant (p < 0.0001). Following a short didactic lecture series, EM residents showed significant improvement of their knowledge of appropriate image utilization on the post-lecture survey. This highlights the need for dedicated radiology-led lecture series for EM residents. This type of program could be implemented yearly and expanded to other departments to promote interdepartmental commuication, increases radiology awareness, improves ordering practices and encourages appropriate imaging utilization.

Definition of the criteria of quality and difficulty of literature in public libraries

Abstract: Public libraries are supposed to provide a wide range of literary materials of all difficulty levels to their users. Here we encounter a dilemma whether it is possible to establish difficulty and quality also as a criterion of systematic classification of literature. In order to get and answer to that dilemma, it is necessary to define the relation between quality and difficulty, as well as the level of possible objective evaluation of literature in accordance with such criteria. Any eventual introduction of such literature classification criteria should be also discussed from the point of view of library management.

Abstract: Method engineering is a field of engineering that has been created a need expressed by engineers. These engineers faced problems in using conventional methods such as SSADM, DSDM, OOAD...In this way, Method engineering was created to intend to develop methods to meet these needs. Therefore, these methods have been employed in a wide range of projects led by these architects. In other contexts, we are led to customize a method for a particular project. The method obtained is called Situational Method (SM).In this paper, we define the basics in order to achieve the monitoring of Situational Method quality in the early stages of its setting up to its effective exploitation. In addition, we identify criteria that allow us to evaluate the construction of a method in terms of quality.Finally, we discuss the choices we have made in this paper and challenges that we have to raise to achieve this quality concept.
