This paper describes cognitive ethnography as a method of choice for game studies, multimedia learning, professional development, leisure studies, and activities where context is important. Cognitive ethnography is efficacious for these activities, as it assumes that human cognition adapts to its natural surroundings (Hutchins, 1995, 2010) with emphasis on analysis of activities as they happen ...

The two-stage missing data interpolation approach of Claerbout (1999) (henceforth, the GEE approach) has been applied with great success (Fomel et al., 1997; Clapp et al., 1998; Crawley, 2000) in the past. The main strength of the approach lies in the ability of the prediction error filter (PEF) to find multiple, hidden correlation in the known data, and then, via regularization, to impose the ...

Google Earth Engine (GEE) has been widely used to process geospatial data in recent years. Although the current GEE platform includes functions for fitting linear regression models, it does not have function fit nonlinear limiting platform’s capacity and application. To circumvent this limitation, work proposes a general adaptation of Levenberg–Marquardt (LM) method models parallel processing f...

In recent years, games and learning researchers have increasingly become interested in the "affinity spaces" (Gee, 2004) around popular videogames, identifying them as instructional spaces (Squire and Giovanetto, 2008) and contexts in which sophisticated reasoning practices are enacted (Steinkuehler and Duncan, 2008). However, the motivation for participation in these communities as well as the...

Semi-parametric approaches based on generalized estimating equation (GEE) are widely used to analyze correlated outcomes in longitudinal settings. In this paper, we present a package CRTgeeDR developed for cluster randomized trials with missing data (CRTs). For use of inverse probability weighting to adjust for missing data in cluster randomized trials (CRTs), we show that other software lead t...

We introduce an approximation to the Gaussian copula likelihood of Song, Li, and Yuan (2009, Biometrics 65, 60-68) used to estimate regression parameters from correlated discrete or mixed bivariate or trivariate outcomes. Our approximation allows estimation of parameters from response vectors of length much larger than three, and is asymptotically equivalent to the Gaussian copula likelihood. W...

The co-twin control design has been widely used in studying the effects of environmental factors on the development of diseases. For binary outcomes that arise from co-twin control studies, the conditional likelihood method is commonly used. This approach, however, does not readily extend to ordinal response data because the standard conditional likelihood does not exist for cumulative logit or...

Goeie kommunikasie is die hoeksteen van die verpleegberoep. Aan die hand van gevalle illustreer die skrywer dat die kind veral gevoelig is vir ’n gebrek aan kommunikasie en dat 'n spesiale poging dus aangewend moet word. Hospitalisasie en veral die skeiding van sy moeder het ’n intense invloed op die kind en sy reaksies hang van verskeie faktore af. Om te voorkom dat die hospitaalervaring horn ...

Interactive technologies provide today’s youth a low stakes sandbox to collect experiences (Gee, 2004) and try tasks and identities (Gee, 1991) that push the boundaries of “known” and open up the world of possibility. Pairing affordances of video games with the possible selves framework (Markus & Nurius, 1986), research involved using The Sims 2 life-simulation properties to encourage a friends...
