The performance of methods for detecting publication bias in meta-analysis was evaluated using Monte Carlo methods. Four methods of bias detection were investigated: Begg's rank correlation, Egger's regression, funnel plot regression, and trim and fill. Five factors were included in the simulation design: number of primary studies in each…

This study explored teachers' pedagogical strategies for using multimedia simulation to structure and support secondary science teaching. Expertise was investigated across a range of classroom settings to analyse how specialist knowledge is situated within and adapted to the teaching and learning context. Analysis of data arising from 10 lesson…

The impact of differences in maternal self-efficacy and infant difficulty on mothers' sensitivity to small changes in the fundamental frequency of an audiotaped infant's cry was explored in 2 experiments. The experiments share in common experimental manipulations of infant difficulty, a laboratory derived measure of maternal efficacy (low,…

The usefulness of assessing individual fit in latent growth curve models was examined. The study used simulated data based on an unconditional and a conditional latent growth curve model with a linear component and a small quadratic component and a linear model was fit to the data. Then the overall fit of linear and quadratic models to these data…

Measures of clinical significance are frequently used to evaluate client change during therapy. Several alternatives to the original method devised by N. S. Jacobson, W. C. Follette, & D. Revenstorf (1984) have been proposed, each purporting to increase accuracy. However, researchers have had little systematic guidance in choosing among…

The authors compare the operating characteristics of the bootstrap-F approach, a direct extension of the work of Berkovits, Hancock, and Nevitt, with Huynh's improved general approximation (IGA) and the Brown-Forsythe (BF) multivariate approach in a mixed repeated measures design when normality and multisample sphericity assumptions do not hold.…

Grounded theory can be effectively introduced in a survey course through a combination of lecture/demonstration and simulation. The class session presented here illustrates a way to introduce graduate students to the process of grounded theory and gain hands-on experience through simulation. The lesson utilizes concepts that the students are…

Like many forms of Pavlovian conditioning, eyelid conditioning displays robust extinction. We used a computer simulation of the cerebellum as a tool to consider the widely accepted view that extinction involves new, inhibitory learning rather than unlearning of acquisition. Previously, this simulation suggested basic mechanistic features of…

Ethnocentrism is a nearly universal syndrome of attitudes and behaviors, typically including in-group favoritism. Empirical evidence suggests that a predisposition to favor in-groups can be easily triggered by even arbitrary group distinctions and that preferential cooperation within groups occurs even when it is individually costly. The authors…

This article makes two contributions to the teaching of business ethics literature. First, it describes the steps involved in developing effective ethical dilemmas to incorporate into a computer-based business simulation. Second, it illustrates these steps by presenting two ethical dilemmas that an instructor can incorporate into any business…

Challenges in reconciling trade liberalization policies and efforts to protect the natural environment provide useful illustrations to underscore important concepts in management education. In particular, the three-way interactions among government, business, and nongovernmental organizations (NGOs) over economic and environmental trade-offs serve…

The Swift Trust exercise provides instructors with the opportunity to discuss the issues of managing trust and distrust perceptions in a team-based design. Lewicki, McAllister, and Bies's (1998) framework is used to allow students to experience the difficulties of deriving a common set of contract requirements based on team dynamics and…

This study examines the effects of changes in family structure on children's economic well-being. An initial shift-share analysis indicates that, had the proportion of children living in female-headed families remained constant since 1970, the 1998 child poverty rate would have been 4.4 percentage points lower than its actual 1998 level of 18.3…

This article describes a specific effort to create a multimedia training technology (A Child Protective Service Investigation Simulator or CPS Simulator) for a representative group of street-level public servants--child protective service (CPS) workers. The article first provides some background on why bias in this area is a significant problem,…

Role-playing is a well regarded learning activity. By participating in this activity, students can apply their knowledge through their assigned roles in a realistic but risk-free situation. The role play stimulates class discussion, dramatizes rhetorical principles about purpose, shows how to adapt a text to an audience of employees in a…
