THE EFFECT OF CORRELATED ARTIFACTS AND TRUE VALIDITY ON THE ACCURACY OF PARAMETER ESTIMATION IN VALIDITY GENERALIZATION

The effect of non-zero intercorrelations among the three artifacts (criterion reliability, predictor reliability, and range restriction on the predictor) and true validity on the accuracy of estimation in two validity generalization models (Model 1and Model 2) was investigated. Only the Thylor Series Approximation 1(TSA1) procedure from Model 1 and the procedure with complete sample-based artifact data from Model 2 were included in this study. Six intercorrelation conditions (zero, low positive, medium positive, low negative, low negative and positive, and medium negative and positive) and two distributions of artifacts were used in this investigation. The two major conclusions from this study are: (a) Both models yielded reasonably accurate estimates of the mean of true validities (M_ρ) and (b) only Model 2 produced accurate estimates of the variance of true validities (V_ρ). The need for additional research for accurately estimating V_ρ when the three artifacts and true validity are correlated is recommended.     

BEHAVIORAL OBSERVATION SCALES AND THE EVALUATION OF PERFORMANCE APPRAISAL EFFECTIVENESS

An earlier article by the present authors (Bernardin and Kane, 1980) pointed out a serious flaw in the conceptual basis of Behavioral Observation Scales (BOS). The present article explains this flaw in more detail and shows that its solution would make BOS indistinguishable from other methods already in existence. The focus then shifts from the conception of appraisal methods to their evaluation with the presentation of a discussion of the special problems of error capitalization that arise in the use of item analysis in the development of multi-item rating scales. This discussion proceeds to describe the correct approach to removing the effects of error capitalization in the evaluation of the psychometric properties of such rating scales.     

Corporate Psychology: An Answer to Occupational Mental Health

Corporate planners acknowledge that productivity is directly related to employee mental health. This recognition is reflected by the recent upsurge of corporate in-house, human resource programs. Although their latent function may be economic rather than humanitarian, these programs nevertheless provide psychological assistance for problems considered to be normal episodes of human development. Counseling psychologists may be the best equipped to work with a corporate clientele because, unlike the clinician, the counselor is trained to work with healthy, instead of disturbed, personalities. Most of the developmental crises encountered by the corporate psychologist are associated with stress, midlife, or career development.     

Online dating system design and relational decision making: Choice,algorithms, and control

One of the most popular ways to initiate romantic relationships today is through online dating. Typical dating systems follow one of three formats, see‐and‐screen (e.g., Match.com ), algorithm (e.g., eHarmony.com ), and blended (e.g., OkCupid.com ), which differ in the amount of individual control and algorithmic involvement they offer users. Do different features affect daters' decisions and expectations regarding relational development with selected partners? Study 1 indicated that although daters appreciated the personal control over mate selection afforded by see‐and‐screen systems, they also enjoyed using algorithmic systems. Study 2 found that blended systems provided “the best of both worlds” by offering dual benefits of control and algorithmic validation during mate selection. Findings shed light on self‐determination theory, decision making, and relationship formation more broadly.     

Rowland Universal Dementia Assessment Scale,Mini‐Mental State Examination and General Practitioner Assessment of Cognition in a multicultural cohort of community‐dwelling older persons with early dementia

Early dementia can be difficult to diagnose in older persons from culturally and linguistically diverse (CALD) backgrounds. The Folstein Mini‐Mental State Examination (MMSE), the General Practitioner Assessment of Cognition (GPCOG) and the Rowland Universal Dementia Assessment Scale (RUDAS) were compared in 151 older, community‐dwelling persons. Receiver operating characteristic (ROC) curve analysis was used to evaluate diagnostic accuracy, while logistic regression was used to evaluate the influence of age, gender, CALD status and years of education. All three instruments were equally accurate in predicting dementia (ROC area under curve 0.92–0.97, p > 0.05 for all comparisons). At the recommended cut‐offs, the RUDAS was best for ruling in dementia (positive LR = 8.77), while the GPCOG was best for ruling out dementia (negative LR = 0.03). All three instruments were influenced by concomitant depression. Whereas the MMSE was influenced by CALD status, the RUDAS and GPCOG were not. While the GPCOG combines participant and informant data, the RUDAS is a stand‐alone measure specifically designed for, and validated in, multicultural populations.     

The Role of Risk‐Taking in Songwriting Success

Creativity involves generating novel concepts and products that are valued by the creator as well as by the public. In this paper, we argue that risk‐taking in songwriting increases the likelihood of any individual's product being valued as creative. By reviewing the case histories of several successful songwriters, we show that heightened creativity is associated with a willingness to express novel ideas as well as a willingness to repeatedly confront, and adapt to the possibility of failure.     

Leibniz on Natural Teleology and the Laws of Optics

This essay examines one of the cornerstones of Leibniz's defense of teleology within the order of nature. The first section explores Leibniz's contributions to the study of geometrical optics, and argues that his "Most Determined Path Principle" or "MDPP" allows him to bring to the fore philosophical issues concerning the legitimacy of teleological explanations by addressing two technical objections raised by Cartesians to non-mechanistic derivations of the laws of optics. The second section argues that, by drawing on laws such as the MDPP, Leibniz is able to introduce a thin notion of teleology that gives him the resources to respond to the most pressing charges of his day against teleological explanations within natural philosophy. Finally, the third section argues that contemporary philosophers have been overly hasty in their dismissal of Leibniz's account of natural teleology, and indeed that their own generally thin conceptions of teleology have left them with few well-motivated resources for resisting his elegant position.     

INVESTMENT IN WORK AND FAMILY ROLES: A TEST OF IDENTITY AND UTILITARIAN MOTIVES

This study compared identity and utilitarian motives as predictors of time investment in work and family roles, using structural equation modeling with a sample of 623 working men and women. We tested within-role and cross-role relationships as well as the reciprocal effects of time invested in one role on time invested in the other role. As predicted, identification with a role was positively related to time invested in that role. However, findings for role utility were more complex. Time investment was positively related to both the pleasure and displeasure associated with a role. These findings suggest that people not only seek pleasure from roles but also invest time coping with role displeasure. The cross-role findings supported resource drain and accommodation but not compensation as explanations of work-family linking mechanisms. Gender analyses suggested that, for men, increased work time investment reduced time devoted to family, but increased family time investment did not affect time devoted to work. However, for women, increased time investment in either work or family reduced time devoted to the other role. These findings suggest that men may have greater reserves of time from roles other than work and family that make it unnecessary for them to draw from work time to meet increased family demands.     

Married Black men's observations of fathers' teachings about husbandhood

It is important to investigate the ways in which sons learn about marriage from men, including biological fathers, male relatives, and social fathers. This study's purpose is to explore Black sons' observations of fathers' teachings about husbandhood. Semistructured interviews were conducted with 52 married Black men who participated in the Pathways to Marriage project in 2010. Findings highlighted developmental pathways and family processes related to modeling husbandhood, demonstrating trust and commitment, managing conflict, protecting and providing, displaying teamwork and partnership, showing love and affection, and imparting beliefs and values. Implications and recommendations for future studies are also discussed.
