Is the use of an online course delivery format, when compared with the more traditional face-to-face format, good or bad in the context of university education? Those who subscribe to the no-significant-difference perspective argue that online delivery is good, because it allows students with time and geographic distance constraints to obtain the education that they need, with no significant ne...

Point of Departure " First Law of Geography " : " Everything is related to everything else, but near things are more related than distant things. " — Waldo Tobler, 1970 Fundamental Dialectological Postulate: " Geographically proximate varieties tend to be more similar than distant ones. " — Nerbonne & Kleiweg, 2007 Tested on different types of data (surveys, corpora) Several kinds of geograph...

Measuring how much cybercrime exists is typically done by first defining cybercrime and then quantifying how many cases fit that definition. The drawback is that definitions vary across countries and many cybercrimes are recorded as traditional crimes. An alternative is to keep traditional definitions of crime and quantify the amount of associated information and communication technologies (ICT...

Abstract Researchers in science and engineering have a long tradition of collaboration, and increasingly carry out these collaborations across geographical distance. Similar trends exist in industry, where virtual teams are increasing in frequency. While we know that such dispersed collaborations are difficult, there is growing evidence of success. The physical and biological sciences have led ...

The concept of comprehensive Grobner bases was introduced by Weispfenning. Montes has proposed an efficient algorithm for computing these bases. But he has not explicitly used Buchberger's criteria in his algorithm. In this paper we prove that we can apply these criteria on Montes algorithm. We propose a modified version of Montes algorithm and evaluate its performance via some examples.

The Internet offers an unprecedented opportunity to construct powerful large-scale medical expert systems (MES). In these systems, a cost-effective medical knowledge acquisition (KA) and management scheme is highly desirable to handle the large quantities of, often conflicting, medical information collected from medical experts in different medical fields and from different geographical regions...

Linked Open Data consists of a large set of structured data knowledge bases which have been linked together, typically using equivalence statements. These equivalences usually take the form of owl:sameAs statements linking individuals, but links between classes are far less common Often, the lack of linking between classes is because the relationships cannot be described as elementary one to on...

The aim of the paper is to shed light on role played by regional knowledge bases in Industry 3.0 fostering new technologies 4.0 European regions (NUTS 3) over period 1991–2015. We find that appear be quite related technologies, with some heterogeneity among different technology fields. investigates geographical implications. probability developing higher are specialized technologies. However, o...

abstract this study uses gravity model to examine the most important determinants of was agricultural trade. to this aim, import and export statistics of iran agricultural products for the period 1380 to 1387 was provided from iran customs organization and other information was obtained from different internet bases. random effects estimating and hausman test ratio result in fixed effects model...
