Interactive effects of levels of individualism–collectivism on cooperation: a meta-analysis
(Wiley, 2013-08) Marcus, Justin; Le, H.; Psychology; MARCUS, Justin
We examined the interactive effects of levels of individualism–collectivism (I–C) on cooperation at work by meta-analytically combining results obtained from 201 studies, representing 225 independent samples. I–C was operationalized at the individual, organizational, and societal levels of analyses. Cooperation was conceptualized at both individual and group levels of analysis. Both cooperative behavior and performance were included as outcomes. The correlation between individual-level I–C and cooperation/performance was stronger in collectivistic as opposed to individualistic societies. Similarly, the correlation between organizational-level I–C and cooperation was stronger in collectivistic societies. Results also indicated that individual-level and organizational-level I–C, but not societal-level I–C, were moderately related to study outcomes. Examination of other potential moderators indicated that neither study setting, I–C dimensionality, nor performance measurement type (objective vs subjective measures) altered these relations. However, a conceptual match between I–C and cooperation was a moderator such that effect sizes were generally larger when I–C and outcomes were both measured at the same level of analysis. Overall, our results indicate that I–C is both theoretically and empirically distinct across the various levels of analyses and that it may be a better predictor of outcomes in collectivistic as opposed to individualistic societies.

The overall odds ratio as an intuitive effect size index for multiple logistic regression: examination of further refinements
(Sage, 2012-12) Le, H.; Marcus, Justin; Psychology; MARCUS, Justin
This study used Monte Carlo simulation to examine the properties of the overall odds ratio (OOR), which was recently introduced as an index for overall effect size in multiple logistic regression. It was found that the OOR was relatively independent of study base rate and performed better than most commonly used R-square analogs in indexing model strength. The authors also illustrate and test a jackknife procedure to correct for the bias in the OOR and estimate its standard error. An example applying the OOR to evaluate logistic regression models predicting organizational turnover is provided. The authors discuss implications and offer recommendations for using the OOR to quantify and compare the effectiveness of logistic regression models in applied research.

Validation of the work-related age-based stereotypes (WAS) scale
(Emerald Group, 2016) Marcus, Justin; Fritzsche, B. A.; Le, H.; Reeves, M. D.; Psychology; MARCUS, Justin
The purpose of this paper is to focus on developing and validating a multidimensional measure of work-related age-based stereotypes (WAS) scale. Based upon a review of the literature, a three-dimensional stereotype content model including both negative (incompetence, inadaptability) and positive (warmth) stereotypes of older workers was created. Construct, convergent, discriminant, and criterion-related validity for the WAS scale were examined across three independent samples constituting both lab-based experimental studies and a field-based survey (total n=1,245). Across all samples, the WAS evidenced good construct, convergent, discriminant, and criterion-related validity. As evidenced by a review of the literature, the WAS is unique in that it measures both negative and positive stereotypes of older workers. Implications for research are discussed.
