Rock abrasivity, as one of the most important parameters affecting the rock drillability, significantly influences the drilling rate in mines. Therefore, rock abrasivity should be carefully evaluated prior to selecting and employing drilling machines. Since the tests for a rock abrasivity assessment require sophisticated laboratory equipment, empirical models can be used to predict rock a...

Researchers have a variety of options when choosing statistical software packages that can perform ordinal logistic regression analyses. However, statistical software, such as Stata, SAS, and SPSS, may use different techniques to estimate the parameters. The purpose of this article is to (1) illustrate the use of Stata, SAS and SPSS to fit proportional odds models using educational data; and (2...

The present study was conducted by comparing two populations in Iran with the aim of identifying the level of...

In this article, I provide a typology of transition words/phrases. This typology comprises 12 dimensions of link words/phrases that capture 277 link words/phrases. Using QDA Miner, WordStat, and SPSS—a computer-assisted mixed methods data analysis software, content analysis software, and statistical software, respectively—I analyzed 74 manuscripts that were submitted to the journal Research in ...

Founders & Survivors is a multi-university and public collaborative project that is building a transnational and inter-generational dataset of life courses generated from the UNESCO recognized convict records of Tasmania. This paper outlines the technical history of the project: mass digitization and archiving online of over 100,000 images; manual scholarly transcription; TEI standard XML data ...

Information passing through internet is generally unrestricted and uncontrollable and a good web content filter acts very much like a sieve. This paper looks at how citizens’ internet viewing can be controlled using content filters to prevent access to illegal sites and malicious contents in Nigeria. Primary data were obtained by administering 100 questionnaires. The data was analyzed by a soft...
