MISSING DATA: A CONCEPTUAL REVIEW FOR APPLIED PSYCHOLOGISTS

There has been conspicuously little research concerning missing data problems in the applied psychology literature. Fortunately, other fields have begun to investigate this issue. These include survey research, marketing, statistics, economics, and biometrics. A review of this literature suggests several trends for applied psychologists. For example, listwise deletion of data is often the least accurate technique to deal with missing data. Other methods for estimating missing data scores may be more accurate and preserve more data for investigators to analyze. Further, the literature reveals that the amount of missing data and the reasons for deletion of data impact how investigators should handle the problem. Finally, there is a great need for more investigation of strategies for dealing with missing data, especially when data are missing in nonrandom or systematic patterns.     

FORMAL AND INFORMAL MENTORSHIPS: A COMPARISON ON MENTORING FUNCTIONS AND CONTRAST WITH NONMENTORED COUNTERPARTS

Research on mentorships has suffered from fragmentation of key issues; specifically, type of mentoring relationship, functions served by the mentor, and outcomes of the mentoring relationship. A field study was conducted comparing 212 protégés who were involved in informally developed mentorships, 53 protégés involved in formal mentor-ship programs, and 284 individuals who did not have mentors. Individuals in informal and formal mentorships were compared along two mentoring dimensions: psychosocial and career-related functions. All groups were compared on three outcome measures: organizational socialization, job satisfaction, and salary. Results indicated protégés in informal mentorships reported more career-related support from their mentors and higher salaries than protégés in formal mentorships. For all outcome variables, protégés in informal mentorships also reported more favorable outcomes than nonmentored individuals. However, outcomes from protégés in formal mentorships were generally not significant from the other two groups. Implications for mentorship practices and research are discussed.     

ON THE INTERCHANGEABILITY OF OBJECTIVE AND SUBJECTIVE MEASURES OF EMPLOYEE PERFORMANCE: A META-ANALYSIS

A meta-analysis of studies containing both objective and subjective ratings of employee performance resulted in a corrected mean correlation of .389. This value, although significantly greater than zero, indicates that objective and subjective performance measures should not be used interchangeably. Moreover, in no moderator subgroup examined did the correlation suggest convergent validity. After discussing issues related to resolving the previous anomalies of primary and meta-analytic results, a secondary analysis suggested that objective and subjective measures of the same construct at the same level may be used inter-changeably. The secondary analysis, however, was based on a very limited sample. Future research should address the appropriate dimensionality of employee performance.     

EVIDENTIARY STANDARDS IN EMPLOYMENT DISCRIMINATION: A VIEW TOWARD THE FUTURE

This article reviews recent changes in evidentiary standards in employment discrimination litigation as they relate to disparate impact theory. Precedents established in Watson v. Fort Worth Bank and Wards Cove Packing Co. v. Atonio , altering the employee's and the employer's responsibilities in discrimination cases are analyzed. In reaction to these and other Supreme Court rulings, Congress introduced a civil rights bill which was eventually signed into law after numerous compromises. The debate surrounding the development of the 1991 Civil Rights Act and the legislation itself are reviewed. With respect to disparate impact, the Act addresses the criteria for establishing a prima facie case (causation), burden of proof standards, and a definition of business necessity. However, a close reading of the Act and a review of recent disparate impact cases suggest the causation and business necessity issues are not fully resolved. Potential implications for managing personnel decision systems in this new environment are discussed.     

Marx,Housework, and Alienation

For different feminist theorists, housework and child rearing are viewed in very different ways. I argue that Marx gives us the categories that allow us to see why housework and child care can be both a paradigm of unalienated labor and also involve the greatest oppression. In developing this argument, a distinction is made between alienation and oppression and the conditions are discussed under which unalienated housework can become oppressive or can become alienated.
