Purpose: Agricultural extension services in poor countries often identify opinion leaders based on criteria such as wealth and social status. We explore the effectiveness of this top-down approach by analysing the role of so-called model and nodal farmers in the diffusion of malt barley in a highland community in Ethiopia. Research approach: We…

Doctoral training is strongly focused on honing research skills at the expense of developing teaching competency. As a result, emerging academics are unprepared for the pedagogical requirements of their early-career academic roles. Employing an action research approach, this study investigates the effectiveness of a competency-based teaching…

In the last decade Australian academic libraries have increasingly aligned their research support services with assessment criteria used in the national research evaluation exercise (Excellence for Research in Australia). The same period has seen growing interest in research impact outside of traditional measures, such as bibliometrics. Social…

The High School Summer Research Program (HSSRP) is a rigorous eight-week research experience that challenges high school students to a novel scientific question in an engineering laboratory at the Henry Samueli School of Engineering and Applied Science (HSSEAS) at the University of California, Los Angeles (UCLA). The program collates highly…

The paper draws on a series of Australian Research Council (ARC) projects aimed at understanding better the process of doctoral examination. The early phase focussed on the Australian doctorate, which functions without a Viva, while the later phase was concerned with comparing the earlier findings with analysis of the United Kingdom (UK) and New…

This study characterized the use of research community partnerships (RCPs) to tailor evidence-based intervention, training, and implementation models for delivery across different childhood problems and service contexts using a survey completed by project principal investigators and community partners. To build on previous RCP research and to…

Order analysis is a measurement technique for the quantitative and generalizable description of complex structures. Relations between the manifest elements of a data matrix and its underlying latent entities and attributes are considered in terms of magnitudes as basic scale units. Magnitude is conceptualized as a difference relation, translated…

The purposes of this study were (1) to test whether the occupational preferences of senior psychology majors could be predicted using a within-subjects analysis of Vroom's model; (2) to examine the predictive validity of valence and instrumentality measures, and (3) to compare the predictive validity of the weighted and unweighted valence models.…

This article presents a description of one analysis of variance components model for estimating proportions of variance in process measures and illustrates this model by applying it to reports of patients' experiences in psychotherapeutic sessions to describe the extent to which these experiences are a function of differences among therapists.…

Using data originally report by others, this paper focuses on the relative merits of three separate statistical approaches to measuring occupational sex discrimination. The sample was a national probability sample of 539 women and 993 men. Demographic factors such as race, sex and age, education, job tenure and supervisory status served as the…

This project investigated the probabilistic interactional structure of counseling interviews conducted by two groups of counselors of differing levels of cognitive complexity, and the consistency of that structure within each group across sequences of two interviews. Analysis of the counselor-client interaction patterns between the two groups of…

The intention of this research is to contribute additional data, hopefully bearing on the solution to some of the problems and indirectly, the cause(s) of Sudden Infant Death Syndrome, and to present ideas for consideration for future SIDS research. (Author/RK)

A research project is described that concerns "temporal adjustment" as one form of a non-wage adjustment in the academic labor market. Receipt of the doctorate, the number and length of post-doctoral fellowships, and the achievement of tenure are temporal factors in academic careers. The change in timing of these factors is a form of…

A procedure for developing a costing model is described. Limitations of a cost analysis are also reviewed, with attention to the problems of handling joint products, obtaining accurate faculty effort data, measuring educational outputs, and calculating marginal costs. A researcher charged with developing a costing model is faced with the task of…

The author describes her career development from mathematics instructor to director of institutional research at a large community college. She discusses the impact of mathematics on her career, illustrates her present job by describing three recently completed research projects, and strongly recommends that mathematics instructors encourage some…
