It is known from studies outside the brain that upon binding to its receptor, angiotensin-(1-7) elicits the release of prostanoids and nitric oxide (NO). Cyclooxygenase (COX) is a key enzyme that converts arachidonic acid to prostaglandins. Since there are no data available so far on the role of COX-2 in the amygdala, in a first step we…

This article presents a discussion of mixed methods (MM) sampling techniques. MM sampling involves combining well-established qualitative and quantitative techniques in creative ways to answer research questions posed by MM research designs. Several issues germane to MM sampling are presented including the differences between probability and…

The authors conducted a 20-year content analysis of the entire field of empirical research on the multicultural counseling competencies (D. W. Sue et al., 1982). They conducted an exhaustive search for empirical research articles using PsycINFO, as well as complete reviews of the past 20 years of several journals (e.g., Journal of Counseling…

The authors reviewed the psychological research on envy. The authors examined definitional challenges associated with studying envy, such as the important distinction between envy proper (which contains hostile feelings) and benign envy (which is free of hostile feelings). The authors concluded that envy is reasonably defined as an unpleasant,…

Fjellstedt and Sulzer-Azaroff (1973) used differential reinforcement of short latencies to decrease a child's latency to comply with instructions. We replicated this contingency with a young man diagnosed with Asperger syndrome across two tasks (question answering and math problem solving). We added a differential reinforcement contingency to…

Many students struggle with statistical concepts such as interaction. In an experimental group, participants took a paper-and-pencil test and then were given training to establish equivalent classes containing four different statistical interactions. All participants formed the equivalence classes and showed maintenance when probes contained novel…

To date, the majority of research on Attention-Deficit/Hyperactivity Disorder (ADHD) has been completed with boys as the predominate participants in study samples. Over the past decade there has been increased attention focused on the characteristics and needs of girls with ADHD. Although much of the research comparing boys and girls with ADHD…

Purpose: The concept of managers assuming developmental roles such as coaches and learning facilitators has received considerable attention in recent years. Yet, despite the growing body of expert opinion that suggests that coaching is an essential core activity of everyday management and leadership, the literature base remains largely…

This study produced a second replication of an investigation of the effects of a multicomponent cognitive-behavioral intervention on the challenging behavior of young children with growing behavioral concerns after traumatic brain injury (TBI). The participants were two young elementary-age children with escalating behavior problems after severe…

UK schools commonly employ a behavioral discipline method comprising rules, rewards awarded when children follow the rules and sanctions when children break them. To date, this approach has had only limited success in halting classroom disruption (Render, Padilla and Krank, 1989; Riley & Rustique-Forrester, 2002; Gutherson & Pickard,…

Frender and Doubilet suggest that Bousfield's ratio of repetitions (RR) is the best measure of clustering in free recall presently available. Conditioning only on the number of words recalled, they determine the mean of RR in the absence of clustering. In this note the null variance of RR is presented. (Author)

The author, a practicing teacher, added his voice to the argument about competitive sport in schools. He suggested that sport can have a violent effect on children's behavior. (Editor/RK)

An experiment in behavior technology is described in which the results indicate that token technology can be an effective technique to increase small group participation when a variety of back-up reinforcers is offered. (Author/HB)

Sixty-four clinicians responded to a brief description of a depressed student by indicating the extent to which each of four possible causes contributed to the depression. (Author)
