This policy brief discusses an empirical simulation exercise that gauges the plausible impact of increased rates of college attainment on a variety of measures of income inequality and economic insecurity. The results reveal that increasing college attainment would shrink gaps between the 90th percentile and lower half of the earnings…

The recent popularity of models that capture the dynamic coevolution of both network structure and behavior has driven the need for summary indices to assess the adequacy of these models to reproduce dynamic properties of scientific or practical importance. Whereas there are several existing indices for assessing the ability of the model to…

The main challenges commonly associated with acquiring practical network engineering skills are the requirements for access to specialised and up-to-date network equipment, as well as the high costs associated with obtaining and maintaining this equipment. The PT Anywhere initiative addresses these challenges by offering a mobile environment for…

In the course of screening a form of a medical licensing exam for items that function differentially (DIF) between men and women, the authors used the traditional Mantel-Haenszel (MH) statistic for initial screening and a Bayesian method for deeper analysis. For very easy items, the MH statistic unexpectedly often found DIF where there was none.…

Exploratory factor analysis (EFA) is a frequently used multivariate analysis technique in statistics. Jennrich and Sampson (1966) solved a significant EFA factor loading matrix rotation problem by deriving the direct Quartimin rotation. Jennrich was also the first to develop standard errors for rotated solutions, although these have still not made…

Games and gaming have always been an influential part of society and culture. Within the last 35 years, due to numerous technology innovations, electronic games in many formats have become ubiquitous in everyday life. This ubiquity has meant that games and gaming have permeated into many fields and disciplines for multiple purposes including…

This chapter takes the somewhat unorthodox stance that the central purpose of an introductory political science course is not to prepare students for future political science courses but rather to prepare them for a lifetime of democratic citizenship. It suggests that the way to do this is not by primarily teaching content but by offering…
