Knowledge that Transforms

The development of optimal human resource practices is often contingent on the accurate statistical testing of potential interventions. Testing the efficacy of HR interventions can be enhanced by taking additional measures to improve statistical power, but the traditional means of increasing power through sample size are often beyond the cost and ability of HR professionals to pursue. This article, therefore, focuses on measurement procedures as an alternative way to increase statistical power for detecting HR intervention effects. Selection of reliable and appropriate measures and subsequent instrumentation are examined as efficacious and cost‐beneficial techniques that can be employed during the planning and designing stage of a study for augmenting statistical power to optimize business decision making.

Over the past decade, the exponential growth in Professional in Human Resources (PHR) and Senior Professional in Human Resources (SPHR) certifications awarded by the Human Resource Certification Institute substantiates the need to reexamine the base rate of HR job announcements that require or prefer such certification. Based on a sample of Web‐based job announcements in 2002, Aguinis, Michaelis, and Jones (2005) reported that only 1.4 percent required or preferred PHR/SPHR certification. Using a similar design, the current study found that 15.6 percent of job announcements required or preferred PHR/SPHR certification, which is nearly 11 times the rate found in the Aguinis et al. (2005) study. Results also suggested the demand for PHR/SPHR certification was positively related to experience, educational level, and job title level, with the base rate reaching 25.1 percent for managerial HR roles.

We compared levels of adverse impact (AI) against minorities and women based on three promotional decision methods for 428 associate store managers of a Fortune 500 retailer: top‐down appraisal (TDA), multisource appraisal (MSA), and an assessment center (AC). We found significant effects for race and minority status (favoring whites) but no significant effects for gender across all three methods. Comparisons were analyzed using two definitions of AI (four‐fifths rule and the Fisher Exact Test) with a selection ratio (SR) of .25. No evidence of AI was found against blacks for any of the methods. For Hispanics, AI was found under the four‐fifths rule for the AC. For women, the four‐fifths rule was violated using TDA. Results provide some partial support for the argument that diversity goals are more likely to be met using assessment centers compared to TDA when the preponderance of raters are white men. Our data also suggest that carefully crafted, job‐related, top‐down appraisal, combined with rater training, may be effective in facilitating the promotion of more women and minorities and reducing the probability of legal problems.

Scholars have suggested that the relationship between voluntary turnover and organizational performance can be moderated by the organizational context in which turnover occurs. However, there are few empirical studies that examine such moderating effects. Using a sample of 161 firms in South Korea, this study investigates how the relationship between voluntary turnover and organizational performance is moderated by three context variables: (1) the degree of organizational usage of employee involvement practices, (2) the degree of organizational investment in employee training and development, and (3) the availability of potential workers. The results demonstrate that employee involvement practices significantly amplify the negative relationship between voluntary turnover and organizational performance, give marginal support for moderation from the availability of potential workers, and provide no support for moderation from the degree of organizational investment in employee training and development. We discuss theoretical and practical implications of this study for enriching our understanding of the relationship between voluntary turnover and organizational performance.

Subsequent to training IT professionals ( n = 35) in skills for performing effectively in a selection interview, 16 were randomly assigned to a transfer of training intervention, written self‐guidance (WSG). This methodology is based on social cognitive and self‐persuasion theories. The results showed that WSG resulted in significantly higher ratings from an interviewer than did those in the control group. Self‐efficacy for interviewing skill mediated the relationship between WSG and performance. A content analysis of the WSG letters showed that the use of self‐affirming and self‐relevant statements was positively related to performance in the selection interview.

The shift toward individualistic career management requires a supportive and developmental career approach. Using coaching practices as a manifestation of such an approach, this study reports on coaching and other career practices that are part of supportive and developmental career management in a Belgium sample ( n = 154). Three other types of career management were identified as well. Supportive and developmental career management was most present in organizations that had a past or current prospector strategy, and was the least present in past or current defenders. The type of business strategy organizations indicated to pursue in the future did not have an influence on the type of career management they currently had.

Based on reinforcement theory, a quasi‐experimental design was used to evaluate the effect of (a) feedback obtained from (b) a relatively neutral third party (namely, mystery shoppers) that was obtained on a (c) variable interval schedule for managers to use to (d) coach their employees. An interrupted time‐series design showed that both employee and organizational performance increased as a result of this intervention. Performance dropped when this intervention was cut back and, subsequently, discontinued. These results were replicated in two additional restaurants.

This study examines how successive outsourcing of recruitment activities to an external provider—also known as recruitment process outsourcing (RPO)—affects graduates' reactions. Using an experimental scenario technique, a total of 158 graduates participated in four hypothetical scenarios that have been developed as an experimental between‐subject design. Results provide support for negative effects of the extent of RPO on graduates' satisfaction with the recruitment process and company attractiveness. More‐over, mediated by graduates' satisfaction with the recruitment process and company attractiveness, an increasing extent of RPO negatively influences job‐acceptance intentions.
