Canonical Correlation and Chi-Square: Relationships and Interpretation

A 2 × 2 chi-square can be computed from a phi coefficient, which is the Pearson correlation between two binomial variables. Similarly, chi-square for larger contingency tables can be computed from canonical correlation coefficients. The authors address the following series of issues involving this relationship: (a) how to represent a contingency table in terms of a correlation matrix involving r - 1 row and c - 1 column dummy predictors; (b) how to compute chi-square from canonical correlations solved from this matrix; (c) how to compute loadings for the omitted row and column variables; and (d) the possible interpretive advantage of describing canonical relationships that comprise chi-square, together with some examples. The proposed procedures integrate chi-square analysis of contingency tables with general correlational theory and serve as an introduction to some recent methods of analysis more widely known by sociologists.     

Meta-analysis of work–family conflict mean differences: Does national context matter?

Work–family conflict continues to be a topic of considerable interest to researchers and practitioners across the globe. In the current study, meta-analysis is used to compare cross-national mean differences in work-to-family conflict and family-to-work conflict across cultural, institutional, and economic aspects of context. No significant differences in work-to-family conflict were detected. Reports of family-to-work conflict were higher in more collectivistic versus more individualistic cultures, in countries with a higher versus a lower economic gender gap, and in countries other than the U.S. versus the U.S.     

Does mentoring matter? A multidisciplinary meta-analysis comparing mentored and non-mentored individuals

The study of mentoring has generally been conducted within disciplinary silos with a specific type of mentoring relationship as a focus. The purpose of this article is to quantitatively review the three major areas of mentoring research (youth, academic, workplace) to determine the overall effect size associated with mentoring outcomes for protégés. We also explored whether the relationship between mentoring and protégé outcomes varied by the type of mentoring relationship (youth, academic, workplace). Results demonstrate that mentoring is associated with a wide range of favorable behavioral, attitudinal, health-related, relational, motivational, and career outcomes, although the effect size is generally small. Some differences were also found across type of mentoring. Generally, larger effect sizes were detected for academic and workplace mentoring compared to youth mentoring. Implications for future research, theory, and applied practice are provided.     

Factors Related to Mentor Reports of Mentoring Functions Provided: Gender and Relational Characteristics

In this study we examined the relationship between mentor gender, protégé gender, mentorship characteristics (e.g., mentorship type, mentorship duration, mentor experience), and mentoring functions provided as reported by mentors. Drawing on research regarding diversified mentorships and interpersonal relationships, we proposed that mentoring effectiveness would vary as a function of the gender of the mentorship participants and the characteristics of the relationship. As hypothesized, several interesting gender differences emerged from the data. Male mentors reported providing more career mentoring to their protégés, whereas female mentors reported providing more psychosocial mentoring. Contrary to expectations, mentors in informal mentorships did not report providing more mentoring than did mentors in formal mentorships. The findings demonstrate the importance of examining mentoring from the perspective of the mentor.     

Opportunities in public policy to support infant and early childhood mental health: the role of psychologists and policymakers

Infant and early childhood mental health practices can be supported by policies and professional standards of care that foster the healthy development of young children. Policies that support infants and toddlers include those that strengthen their families to provide a family environment that promotes mental wellness. Policy issues for infants, toddlers, and young children have come to the forefront of thinking as children need a "voice" to advocate for their support and care. This article (a) highlights several important policy areas that support the social-emotional development of very young children and (b) gives examples of current policy accomplishments and challenges. The article offers a policy agenda to promote the mental health of infants and young children and suggests ways that psychologists can engage with policymakers to promote policies that foster infant mental health, including contributing to the knowledge base that informs policy decisions, educating the public and policymakers about early childhood development and mental wellness, forming community partnerships to identify and address infant mental health risks, and participating in the development of policy recommendations that improve access to evidence-based practices in infant mental health.     

Effects of daily morphine administration and deprivation on choice and demand for remifentanil and cocaine in rhesus monkeys

Choice procedures have indicated that the relative reinforcing effectiveness of opioid drugs increases during opioid withdrawal. The demand curve, an absolute measure of reinforcer value, has not been applied to this question. The present study assessed whether mild morphine withdrawal would increase demand for or choice of remifentanil or cocaine. Four rhesus monkeys chose between remifentanil and cocaine during daily sessions. Demand curves for both drugs were subsequently obtained. The effects of daily injections of 3.2 mg/kg morphine on both choice and demand for these drugs was assayed 3 and 20.5 hr after each morphine injection, and then during a postmorphine period. Three hours following morphine injections, choice of remifentanil over cocaine decreased and demand for remifentanil--but not cocaine--became more elastic. During morphine withdrawal (20.5 hr postinjection), choice of remifentanil increased and remifentanil demand became more inelastic in 3 of 4 monkeys. Cocaine demand also became more inelastic during this period. Four to five weeks following the morphine regimen, demand for both drugs was more inelastic relative to the initial determination. The results suggest that both the relative and absolute reinforcing effectiveness of remifentanil decreased following morphine administration and increased during morphine withdrawal. The absolute reinforcing effectiveness of cocaine also increased during morphine withdrawal. In addition, extended exposure to drug self-administration and/or exposure to the morphine regimen produced long-term increases in demand for both drugs.     

Rewarding Good Citizens: The Relationship Between Citizenship Behavior,Gender, and Organizational Rewards1

The relationship between organizational citizenship behavior (OCB) and two organizational rewards—salary and promotion—was examined. Employee gender also was tested as a moderator. Data from 440 individuals employed in multiple settings indicated that individuals who reported engaging more frequently in OCB directed toward the organization (OCBO) also reported receiving more promotions. Further, results indicated that gender was a moderator such that the relationship between OCBO and promotion was stronger for males than for females. The results also revealed an interaction between OCB directed toward individuals (OCBI) and OCBO. Specifically, high OCBI and low OCBO related to lower promotion rates than did low OCBI and low OCBO. Results are discussed in terms of implications for individual career development.
