The personal factor in evaluation use : A case study of a steering committee's use of a conservation tillage survey

In 1985 a statewide farmer survey about conservation tillage was conducted. It provided baseline data for a major energy conservation project. The data were used for 2 years, at which time a case study was undertaken to identify factors which influenced the tillage survey's use. The influence of the personal factor on evaluation use had been identified prior to planning the tillage survey. Therefore, the process used for conducting the tillage survey capitalized on the personal factor by using a team approach. The case study identified ways intended users actually used the tillage survey results, associated these findings with the team strategy, and generated important factors contributing to evaluation use when the personal factor was accounted for. Factors supporting the personal factor which appear to have influenced use were timeliness, intended users' ownership of the information, interaction among decision makers and the evaluator, methodological appropriateness and quality, and planning for use of the results.     

QUESTIONNAIRE VALIDATION BY CONFIRMATORY FACTOR ANALYSIS: AN IMPROVEMENT OVER MULTITRAIT-MULTIMETHOD MATRICES*

The Campbell and Fiske criteria for assessing the construct validity of multitrait-multimethod (MTMM) matrices has had a long history of use. While various statistical techniques, including ANOVA, have attempted to provide rigor to the MTMM matrix design, numerous problems still remain unsolved. Part of the problem in using an MTMM matrix is the assumption of measurement independence. This study attempts to illustrate the misleading inferences that often occur from MTMM analysis when method variance overlap is not accurately assessed. Three questionnaires were designed that were not method independent. Traditional procedures for assessing MTMM matrices suggested the three scaling formats used were not burdened with unusual method variance. A reanalysis of the MTMM matrix employing a Confirmatory Factor Analysis technique illustrated that method variance was a problem. Finally, the need for studies that concentrate on the nature of method variance, its causes and effects, is discussed.     

Effects of Interaction Experiences and Undergraduate Coursework on Attitudes Toward Gay and Lesbian Issues

College experiences can expand knowledge, decrease negative stereotypes, and increase acceptance toward diversity, especially regarding gay and lesbian issues. This study found that the more interaction undergraduate students have with gay and lesbian people on campus, the more accepting their attitudes are regarding (1) same-sex, consensual sex, (2) same-sex relations between adults is not unnatural, (3) vote for a gay presidential candidate, (4) friends with a feminine man, (5) friends with a masculine woman, (6) knowledge of GL issues important for future career, and (7) comfortable with GL roommate. Furthermore, the more undergraduate students are exposed to coursework addressing gay and lesbian issues, the more positive their attitudes are regarding the importance of knowledge of gay/lesbian issues for future career and comfort with a gay/lesbian roommate. Discussion explores possible long-term implications of systematic interaction experiences and coursework at all levels within the educational system to prevent negative attitude formation.     

Failure of Muslim Leadership in America From the Perspective of First-Generation Muslim Americans: A Phenomenological Study

While leadership is a foundational component of guidance in most societies, Muslim children born in America to immigrant parents lack such guidance. A qualitative case study was recently conducted with six first-generation Muslim American college students and professionals. The purpose of this study was six-fold: to examine the concept of leadership in Muslim communities in America, to observe perceptions of Muslim leadership in mosques and community centers, to examine the practice and beliefs of Muslims in America, to view the social interaction of Muslim Americans within their community, to view the mentorship and leadership aspects of Muslim Americans in their community and to inspect marital and cultural aspects within those societies. Findings reveal four themes that show that Muslim Americans are subject to role confusion as they go through adolescence and need a leadership role model to assist them through this stage.     

Defining terms in behavior analysis: Reinforcer and discriminative stimulus

Many definitions of reinforcer and discriminative stimulus found in behavioral texts include a requirement of temporal proximity between stimulus and response. However, this requirement is not consistently adopted. We present additional evidence from a questionnaire that was sent to members of the editorial boards of several behavioral journals showing that there is not universal agreement concerning the temporal parameters accepted in the definitions of reinforcer and discriminative stimulus. We suggest that the disagreement over the definitions of these essential terms ought to be at least addressed if not resolved. Because the discrepancy usually occurs when the behavior of verbal humans is at issue, we urge behavior analysts to be conservative when extending the terms reinforcer and discriminative stimulus from the behavior of nonhumans in the laboratory to human behavior where the effects of many stimuli may depend in part on sophisticated verbal repertoires.
