The purpose of this study was to investigate the tenability of a proposed path-analytic model relating resourcefulness and persistence in the context of adult autonomous learning. Data collected from a nonprobability sample of 492 American adults using valid and reliable measures for resourcefulness and persistence were analyzed. Results suggest…

Covariance structure models are applied to gene expression data using a factor model, a path model, and their combination. The factor model is based on a few factors that capture most of the expression information. A common factor of a group of genes may represent a common protein factor for the transcript of the co-expressed genes, and hence, it…

Despite a large body of literature addressing relationship quality and domestic violence in women's same-sex relationships, few studies have empirically examined how stress specific to living as a lesbian or bisexual woman might correlate with these relationship variables. Degree of outness, internalized homophobia, lifetime and recent experiences…

This study examines the effects of coalition leadership and governance on member participation in voluntary community health coalitions. Path modeling was used to explore how leadership and governance processes in coalitions affect existing member costs, benefits, and levels of participation. It was hypothesized that the effects of coalition…

This study examines the process whereby functional disability amplifies depressive symptoms through decreasing perceived social support and psychological resources. The study analyzed two waves of panel data (1986 to 1992) of a large sample of older adults from the National Institutes of Aging Established Populations for Epidemiologic Studies of…

To steer a course through the world, people are almost entirely dependent on visual information, of which a key component is optic flow. In many models of locomotion, heading is described as the fundamental control variable; however, it has also been shown that fixating points along or near one's future path could be the basis of an efficient…

This paper reports on a study that examined both the concurrent and longitudinal connections between multiple components of the home environment and indicators of preschool-aged children's literacy and language development. Data were collected from 85 parents and their children at two different times. Results of structural path models indicated…

Objective: The potential path from sexual abuse as a child to the current risk of physical abuse by mothers was assessed. Ontogenic variables including the experience of the parent's sexual abuse as a child and current depression or substance abuse were expected to have a greater impact on the risk of child abuse than microsystem and exosystem…

This report presents an analysis of an expert performing a highly interactive computer task. The analysis uses GOMS models, specifying the Goals, Operators, Methods, and Selection rules used by the expert; the GOMS models are implemented within a unified theory of cognition called Soar. Two models are presented, one with function-level operators,…

The study presented in this document was designed to test, through path analysis, a modified version of the Bean and Metzner (1985) model of nontraditional student attrition in an effort to understand why older students frequently dropped out of a large public university in the Midwest. Four variables from Bean and Metzner's model were deleted and…

Path models are formulated to determine the relative causal impact of evaluation of reward policies, organizational stature, and professional field on three forms of faculty support of institutional authority structure. Findings indicate that evaluation of reward policies has the strongest effect. (Author)

Researchers are divided as to whether loneliness is a result of diminished quantity or quality of social interaction. Although results have been produced which support each position, few studies have examined the relationship between the two. To qualify the relationship between the quantitative and qualitative aspects of loneliness by exploring…

Author concluded that Jencks' book was about the inequality of pay in the United States and its relationship to family background as well as educational opportunity. (Author/RK)

Argues that comparison of "effects coefficients" derived from path analysis is the preferred method of assessing the relative impact of different independent variables on a given dependent variable. Available from: American Political Science Association, 1527 New Hampshire Avenue, N.W., Washington, DC 20036; $10.50 single copy.…

Defines structural equation modeling (SEM) and points out its relation to other more familiar data-analytic techniques, as well as some of the potentials and pitfalls of SEM in the analysis of developmental data. Discussion focuses on causal modeling, path diagrams, ordinary least-squares regression analysis, and powerful methods for model…
