[source] Student Hits in an Internet-Supported Course: How Can Instructors Use Them and What Do They Mean?DECISION SCIENCES JOURNAL OF INNOVATIVE EDUCATION, Issue 2 2003Andrew, Ellen Baugher Varanelli Weisbord ABSTRACT The world of education is changing as Web-based technology and courseware are increasingly used for delivery of course material. In this environment, instructors may need new measures for determining student involvement, and ultimately student performance. This study examines whether hits to a Web site have any value for predicting student performance in a traditional course supported by Web activities. Total Hits at the end of the semester was used as one measure. Hit Consistency, determined by assigning a 0 when no hits occurred between class meetings and by assigning a 1 when one or more hits occurred between class meetings, was another. Hit Consistency was significantly correlated with course average (r= .37, p < .001) for 108 students in two course sections. Hit Consistency started to show a significant relationship with course average by the third week (or class). Total Hits was not found to significantly correlate with course average (r= .08, p > .05) at the end of the semester or during any week. These results suggest that students who consistently access a Web site will perform better than those who do not. When Hit Consistency and Total Hits were entered as independent variables into a stepwise regression with course average as the dependent variable, the model was enhanced by the addition of Total Hits after Hit Consistency was entered (R= .43, p < .001). Hierarchical regression analysis in which cumulative grade point average was entered as the first controlling variable suggested that online access may go beyond the predictive value of achievement alone for predicting course performance with Hit Consistency appearing to be the dominant causal variable. [source] Detection of access to terror-related Web sites using an Advanced Terror Detection System (ATDS)JOURNAL OF THE AMERICAN SOCIETY FOR INFORMATION SCIENCE AND TECHNOLOGY, Issue 2 2010Yuval Elovici Terrorist groups use the Web as their infrastructure for various purposes. One example is the forming of new local cells that may later become active and perform acts of terror. The Advanced Terrorist Detection System (ATDS), is aimed at tracking down online access to abnormal content, which may include terrorist-generated sites, by analyzing the content of information accessed by the Web users. ATDS operates in two modes: the training mode and the detection mode. In the training mode, ATDS determines the typical interests of a prespecified group of users by processing the Web pages accessed by these users over time. In the detection mode, ATDS performs real-time monitoring of the Web traffic generated by the monitored group, analyzes the content of the accessed Web pages, and issues an alarm if the accessed information is not within the typical interests of that group and similar to the terrorist interests. An experimental version of ATDS was implemented and evaluated in a local network environment. The results suggest that when optimally tuned the system can reach high detection rates of up to 100% in case of continuous access to a series of terrorist Web pages. [source] Epidemiology underpinning research in the aetiology of orofacial clefts,ORTHODONTICS & CRANIOFACIAL RESEARCH, Issue 3 2007Peter Mossey Structured Abstract Author,,, Mossey P Introduction,,, Epidemiological information gathered through birth defects surveillance is an important adjunct to carrying out clinical and aetiological research. Information on the incidence in the population, causative risk factors and providing baseline data prior to intervention are all important elements. Under the auspices of the World Health Organisation, it was agreed that a global registry and database on craniofacial anomalies should be created and this, the International Database on Craniofacial Anomalies (ICDFA) was designed to gather information on craniofacial abnormalities from existing birth defects registries and databases around the world to become a resource underpinning research. There are currently 62 registries covering 2 million births per year contributing to a database along with information on the size and type of studies used to collect the information, any variation in ascertainment and on the inclusion of syndromes and associated abnormalities. Generation of hypotheses,,, From the epidemiological data collected it is possible to carry out meta-analysis and to search for trends and consistencies in the data that enable hypothesis to be generated. Issues such as geographical distribution, ethnicity, gender, associated abnormalities and clefts in stillbirths can all be examined in a meta-analytical approach. Collection of information on risk factors such as maternal illnesses, medications, lifestyle factors, nutrition and perhaps occupational exposures enables investigation into environmental contribution to causality and genetic predisposition. A range of techniques are currently being used to identify new candidate genes and ultimately it will be necessary to test genetic and environmental hypothesis in the context of human population studies. Conclusions,,, It is only by consistency of association between different populations with different gene pools and maternal exposures, lifestyles, nutrition etc that conclusive evidence regarding causality will be found. It is therefore essential, and a major objective of the WHO that international multicentre collaborative studies are setup to gather the appropriate evidence and improve knowledge and the cause of birth defects in general and orofacial clefts in particular, with the ultimate humanitarian and scientific objective of the WHO being primary prevention. Clinical utility and implications,,, This IDCFA project fulfils three basic objectives namely to enable global surveillance of CFA; to create online access to those who wish to contribute to the IDCFA, and to develop an online directory of resources on craniofacial anomalies for the support of research and improving quality of care. The next sttif for IPDTOC are to expand the number of participating registries and to actively collect data on other craniofacial birth defects. [source] The Potsdam plates of the Carte du Ciel project: I. Present inventory and plate catalogueASTRONOMISCHE NACHRICHTEN, Issue 8 2009K. Tsvetkova Abstract We present an inventory ofthe Carte du Ciel (CdC) plates stored in the Astrophysical Institute Potsdam. The Potsdam CdC zone (+32° to +39°) was divided into 1232 areas and about 2200 plates from the first and second epochs were obtained within the framework of the CdC project. At present, only 977 plates (45% of all) are stored in AIP, the others got lost during the Second World War. The plates for the first epoch measurements had been obtained during the period 1893 May, 1900 February. The plates for the second epoch (1913 August,1924 February) can be separated into two time intervals according to the observer and the observing method used: from 1913 August till 1914 July, and from 1916 February to 1924 February. The present work aims to provide online access to the plate information, given in the plate catalogue and is the first step to online access to the plate images digitized with flatbed scanners.
