Situational and Dispositional Predictors of Performance: A Test of the Hypothesized Machiavellianism Structure Interaction Among Sales Persons1

The hypothesized interaction found in laboratory studies between situational structure and Machiavellianism was tested on working samples of sales representatives. The results suggested that success or failure of Machiavellian tactics used in sales organizations appears to depend on the organization's structure: In loosely structured sales organizations high Machiavellians significantly outperformed low Machiavellians, but in tightly structured sales organizations, high Machiavellians failed to outperform low Machiavellians. These results and implications for future research are discussed.     

Activity settings as the unit of analysis: A theoretical basis for community intervention and development

Theory, methods, and action develop within context, one of which is the intellectual climate of an era. Community psychology is directly and indirectly interactive with many intellectual currents, such as postmodernism, semiotics, hermeneutics, and dialogism. These ideas are discussed as they impact on community psychology, with an emphasis on the reemergence of meaning as a central condition of psychology and community. Meaning is of key importance to the unifying concept in the transactional theoretical model which is presented. How this model might serve as a conceptual framework for an asset approach to community intervention and development is discussed. Increasingly, it is recognized that the development of theory to guide community research and action is necessary to advance intervention and to realize the potential of community psychology. It is argued that community psychology is positioned by concepts and practice squarely at the point of emerging thought, and can make fuondational contributions to general social science. The next article in this special section illustrates concepts of this model in an early education program and the remaining article illustrates the influence of ecocultural factors.     

A model system for psychotherapy research data management

An on-line data management system was developed to provide optimal access to research data. The specific application involved collecting data on four outcome measures from patients receiving brief psychotherapy to ameliorate a stress response syndrome. The on-line data management system also was designed to be transported to other research settings; a variety of other applications of this system are suggested. The need for such a system, the elements that it comprises, its operation, and its availability also are covered.     

Improving Prediction of Academic Achievement for Transfer Students

The most widely used index for admission of transfer students, grade-point average at prior college, was found to be minimally correlated with subsequent grades. Better predictors of transfer GPA were high school GPA and scores on tests of English usage and mechanical reasoning. While based on 260 transfers at one university, these results suggest that a combination of other academic and intellective variables should replace the traditional transfer predictor—a C average at some other school.     

Variables determining the effects of delay in reinforcement,

Procedures were discovered for maintaining a small fixed-ratio performance under 24-hr delay in reinforcement, by appropriate manipulation of the length of delay, amount of food delivered, and size of the fixed ratio. Other experiments showed that (1) the parameters discovered in the first experiment could produce the same result without the complex history of the first procedures; (2) the same parameters of the delayed-reinforcement procedure could maintain an explicit chain of responses; (3) gradual increase in the delay in reinforcement from small to large values was not a necessary condition for achieving the major result, if large amounts of food were delivered as reinforcement and all of the behaviors were first under good control of the relevant stimuli with short delays.     

Examining Relationships Among Ethnicity,PTSD, Life Functioning,and Comorbidity in Female OEF/OIF Veterans

There is much literature on posttraumatic stress disorder (PTSD) and male combat veterans, but little on PTSD by gender and ethnicity among women combat veterans. We examine ethnic differences in PTSD and comorbid disorders among 37 Hispanic, 27 White, and 15 Native female Operaton Enduring Freedom/Operation Iraqi Freedom (OEF/OIF) combat veterans. Participants completed the Clinician-Administered PTSD Scale (CAPS), the Structured Clinical Interview for DSM-IV, Axis I (SCID-Axis I and II), Life Events Checklist (LEC), Military Stress Exposure Questionnaire (MSEQ), and the Medical Outcomes Study Short Form-36 (SF-36). Hispanics differed from Whites in having less education, more trauma exposure, higher levels of PTSD, mood disorder comorbidity, and poorer physical and emotional functioning. Natives differed from Whites with more trauma exposure, higher levels of PTSD, poorer emotional functioning, and higher rates of Cluster B PDs.     

Higher-order exploratory factor analysis of the Reynolds Intellectual Assessment Scales with a referred sample

The factor structure of the Reynolds Intellectual Assessment Scales (RIAS; [Reynolds, C.R., & Kamphaus, R.W. (2003). Reynolds Intellectual Assessment Scales. Lutz, FL: Psychological Assessment Resources, Inc.]) was investigated with a large (N = 1163) independent sample of referred students (ages 6-18). More rigorous factor extraction criteria (viz., Horn's parallel analysis (HPA); [Horn, J.L. (1965). A rationale and test for the number of factors in factor analysis. Psychometrika, 30, 179-185.], and Minimum Average Partial (MAP) analysis; [Velicer, W.F. (1976). Determining the number of components from the matrix of partial correlations. Psychometrika, 41, 321-327.]), in addition to those used in RIAS development, were investigated. Exploratory factor analyses using both orthogonal and oblique rotations and higher-order exploratory factor analyses using the Schmid and Leiman [Schmid, J., and Leiman, J.M. (1957). The development of hierarchical factor solutions. Psychometrika, 22, 53-61.] procedure were conducted. All factor extraction criteria indicated extraction of only one factor. Oblique rotations resulted in different results than orthogonal rotations, and higher-order factor analysis indicated the largest amount of variance was accounted for by the general intelligence factor. The proposed three-factor solution was not supported. Implications for the use of the RIAS with similarly referred students are discussed.
