    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.

    Not so "traditional" anymore? generational shifts on schwartz values in Turkey
    (Sage, 2017) Marcus, Justin; Ceylan, S.; Ergin, Canan; Psychology; ERGİN, Gül Canan; MARCUS, Justin
    We compare generational change in culturally related personal values as represented by the Schwartz values taxonomy, across two decades of individuals representing independent samples of the urban, Turkish workforce, employed in a variety of occupations and in numerous urban centers, in both 1998 and 2009 (N = 779). Results indicate that whereas self-transcendence (harmony) and conservation (collectivism) values have decreased over time, self-enhancement (mastery) has increased. Implications for research and practice are discussed.

    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.

    One size doesn't fit all: toward a theory on the intersectional salience of ageism at work
    (Sage, 2015) Marcus, Justin; Fritzsche, B. A.; Psychology; MARCUS, Justin
    Much of the research on the effects of age in the workplace has ignored the role of contextual factors, and the intersection of multiple group identities. In seeking to address these shortcomings, we provide a theoretical integration and review. First, we review the literature on contextual factors that determine age salience. We then provide a review of the major and competing theories on the consequences of multiple subordinate group status on work outcomes. Finally, we seek to integrate these multiple streams of thought into a unified framework, by identifying when and how competing aspects of group membership become salient, and the consequences of category membership constellations for various subgroups of older workers. A theoretical framework and accompanying propositions are presented.

    Eradicating employment discrimination: toward a cultural values perspective
    (Wiley, 2013-12) Marcus, Justin; Psychology; MARCUS, Justin
    The article offers the author's insights on the paper by A. Lindsey and colleagues regarding the reduction of discrimination in employment. The author argues that the paper failed to provide a model by which diversity can be discussed and addressed. He discusses the cultural mosaic theory which states that shared cultural identities arise from interpersonal interactions and self. He cites some applications of the cultural values concept such as in employee recruitment, inclusion, and retention.

    "Old oxen cannot plow": Stereotype themes of older adults in Turkish folklore
    (Oxford Publishing, 2015) Marcus, Justin; Sabuncu, Neslihan ; Undergraduate English Program; Psychology; MARCUS, Justin; SABUNCU, Ayşe Neslihan
    Purpose of the Study: Although much research has established the nature of attitudes and stereotypes toward older adults, there are conflicting explanations for the root cause of ageism, including the sociocultural view and interpersonal views, that age bias against older adults is uniquely a product of modernity and occurs through social interactions, and the evolutionary view and intraindividual views, that age bias against older adults is rooted in our naturally occurring and individually held fear of death. We make initial investigations into resolving this conflict, by analyzing literature from a society predating the Industrial Revolution, the society of Ottoman Turks. Design and Methods: Using Grounded Theory, we analyzed 1,555 Turkish fairy tales of the most well-known older adult in Turkish folklore, Nasreddin Hoca, for stereotype themes of older adults. Using the same method, we then analyzed 22,000+ Turkish say-ings and proverbs for the same themes. Results: Results indicated older adults to be viewed both positively and negatively. Positive stereotypes included wisdom, warmth, deserving of respect, and retirement. Negative stereotypes included incompetence, inadaptability, and frailty/nearing of death. Older females were viewed more negatively relative to older males. Implications: Results indicated views of older adults to parallel those found in contem-porary research. Results have implications for the design of interventions to reduce age-ism and on the cross-cultural generalizability of age-based stereotypes.

    Students’ self-presentation on Facebook: an examination of personality and self-construal factors
    (Elsevier, 2012-11) Chen, B.; Marcus, Justin; Psychology; MARCUS, Justin
    The present research seeks to extend existing theory on self-disclosure to the online arena in higher educational institutions and contribute to the knowledge base and understanding about the use of a popular social networking site (SNS), Facebook, by college students. We conducted a non-experimental study to investigate how university students (N = 463) use Facebook, and examined the roles that personality and culture play in disclosure of information in online SNS-based environments. Results showed that individuals do disclose differently online vs. in-person, and that both culture and personality matter. Specifically, it was found that collectivistic individuals low on extraversion and interacting in an online environment disclosed the least honest and the most audience-relevant information, as compared to others. Exploratory analyses also indicate that students use sites such as Facebook primarily to maintain existing personal relationships and selectively used privacy settings to control their self-presentation on SNSs. The findings of this study offer insight into understanding college students’ self-disclosure on SNS, add to the literature on personality and self-disclosure, and shape future directions for research and practice on online self-presentation.

    One too many categories: an experimental test on the effectiveness of a dual-identity recategorization intervention on age-based bias
    (Elsevier, 2014-12) Marcus, Justin; Fritzsche, B. A.; Psychology; MARCUS, Justin
    A laboratory experiment was conducted on a convenient sample of N = 724 introductory Psychology students from the southeastern United States, to test the effectiveness of a dual identity recategorization intervention when applied on age bias toward a hypothetical older adult, when applied on individuals both low and high on the spectrum of ageism, and when applied on members of the naturally occurring in-group, younger adults. As predicted by Optimal Distinctiveness Theory, the intervention served to worsen evaluations of an in-group target vis-à-vis a control group that was not exposed to the intervention, and especially when applied on individuals possessing lower amounts of the in-group bias in question, ageism. Moreover, although age-based stereotyping and in-group bias against an older applicant was demonstrated, the intervention was found to have no effect in changing evaluations of an older target relative to the control group. Results and implications for future research are discussed.

    The senior discount: biases against older career changers
    (Wiley, 2013-02) Fritzsche, B.; Marcus, Justin; Psychology; MARCUS, Justin
    This study examined age discrimination in between- vs. within-career job transitions. We expected that older workers transitioning into a new field would experience greater age discrimination than those who change jobs within the same field, particularly when amount of prior job experience is not made salient, and particularly when decision-makers were highly prejudiced. Results suggested that younger job applicants received higher suitability ratings than older job applicants, and job applicants making a within-career transition were rated higher than those making a between-career transition. As hypothesized, older job applicants making between-career transitions would receive the lowest ratings of suitability for hire when no information regarding experience was presented, and when decision-makers were highly prejudiced. Implications for the aging workforce are discussed.

    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.
