A strong, positive science, technology, engineering, and mathematics (STEM) identity is a predictor of future career choice in a STEM field. In this commentary, major concepts are explored within and among four different research studies with implications regarding STEM or science identity. This commentary describes ways in which one can view STEM…

Modern zoological gardens have invested substantial resources in technology to deliver environmental education concepts to visitors. Investment in these media reflects a currently unsubstantiated belief that visitors will both use and learn from these media alongside more traditional and less costly displays. This paper proposes a model that…

"Theory as Method: Small Theories of Treatments," by Mark W. Lipsey, is one of the most influential and highly cited articles to appear in "New Directions for Evaluation." It articulated an approach in which methods for studying causation depend, in large part, on what is known about the theory underlying the program. Lipsey discussed the benefits…

A systems perspective on the development of disruptive behavioral disorders is presented and discussed with an emphasis on correlated constraints. The concept of correlated constraints suggests that behavior development involves the interconnected contributions of multiple factors working together as a system. Implications are considered in…

Examines the Rodgers, Rowe, and Buster (1998) epidemic model of the onset of social activities for adolescent sexuality. Maintains that its strengths include its theoretical potential to generate new hypotheses for further testing at the individual level. Asserts that its limitations include the lack of a well-developed statistical framework and…

Reviews and comments on Stoolmiller's (1998) criticisms of an epidemic model of the onset of social activities (EMOSA) and about nonlinear modeling in general. Discusses the idea of social contagion as a general theoretical tool. (Author)

This commentary on Enrique Gracia's (2003) article, "Social Isolation from Communities and Child Maltreatment: A Cross-Cultural Perspective," discusses the relationship of neighborhood context to child maltreatment. The difficulty of sorting out individual and contextual factors is emphasized, along with the problem of clearly defining the unit of…

Expands an existing nonlinear dynamic epidemic model of onset of social activities (EMOSA), motivated by social contagion theory, to quantify the likelihood of pregnancy for adolescent girls of different sexuality statuses. Compares five sexuality/pregnancy models to explain variance in national prevalence curves. Finds that adolescent girls have…

Multiple regression and path analyses of 29 demographic, social, and psychological variables were carried out to determine those variables that influenced the use of community-based mental health services by the Hispanic elderly. The variables were classified using the Andersen and Newman framework which conceptualizes the individual's demand for…

Describes research that measured personal, national, and occupational identity among Jamaican postsecondary students. Observes that the variable of attitudes toward minorities was strongly related to personal and national identity, and suggests encouragement of positive attitudes toward ethnic groups in order to foster acceptance of differences in…

It is argued that "unplanned" language policy and planning are an important but underexamined aspect of the field of language planning. Planners must consider the problems raised by "unplanned" aspects and scholars must document their effects on language planning. (Contains 15 references.) (LB)

The social psychological constructs postulated by Garner, Clement et al. are integrated into a proposed new framework of second/foreign language (L2) learning motivation. The proposed model comprises three levels: language, learner, and learning situation. Practical examples for motivating L2 learners are presented. (55 references) (LB)

Challenges the use of ethnicity as a predictor of school-level achievement because of its lack of manipulability, lack of intrinsic association with home processes, and inability to advance the understanding of models of school-level achievement. The use of socioeconomic status as a more robust predictor of school-level achievement is recommended.…

This article reviews the literature on the inadequacy and adequacy of parenting by persons with mental retardation and offers new foci for research. It examines issues in predicting parenting inadequacy based on parental knowledge and skill, health care and safety, decision making, interaction, and child outcomes in terms of cognitive delay and…

A study conducted in two types of laboratory settings and one school setting tested a model of the development of emotional expression. The model included: (1) societal, peer, and family influences; (2) self-factors, such as physiological, affective, motivation, cognitive, and personality variables; and (3) self-mediators, which act as filters…
