“…It is worth noting, though, that despite a small effect we did survey four professional groups. Thus our results should generalize to a relatively broad population of organizations and employees (Armstrong and Henson, 2004).…”

Technology-assisted supplemental work and work-to-family conflict: The role of instrumentality beliefs, organizational expectations and time management

People engage in technology-assisted supplemental work (TASW) when they perform role-prescribed tasks at home after regular work hours with the aid of technological tools such as laptops, cell phones, BlackBerries®, and PDAs. Drawing from the technology acceptance model, we hypothesized and found that instrumentality beliefs (perceived usefulness) and organizational expectations (psychological climate) were positively related to TASW. In addition, we hypothesized and found that TASW was positively related to work-to-family conflict. However, time management (setting goals and priorities) moderated the relationship such that people who apply certain time management strategies may reduce the negative influence of TASW on their lives at home.

“…Effect sizes were also calculated for each of the mean differences. There is some agreement in the literature as to the value in using effect size in addition to inferential tests, not only because of the threat of a Type II error when participant numbers are small but also because an effect size provides a measure of practical or clinical significance (Armstrong & Henson, 2004;Osborne, 2008;Ruscio, 2008). Effect sizes for setting were calculated for (a) total engagement, (b) active engagement, (c) passive engagement, (d) adult interaction, and (e) peer interaction by dividing mean difference by the pooled standard deviation.…”

The engagement and interaction of 12 children with autism spectrum disorder (ASD) were measured during free play in segregated and inclusive prior-to-school early childhood settings to compare the learning opportunities provided in each type of setting. Ratings of overall engagement and the frequency and quality of interaction were also compared across the two types of setting. Although a satisfactory level of engagement was found for segregated and inclusive settings, the children were, on average, slightly better engaged in the segregated settings. Adult interaction was significantly higher in the segregated settings, but the difference in the amount of peer interaction only marginally favored the inclusive settings. Variations in the engagement and interaction across individual children were identified. The implications of these findings for optimizing learning opportunities for children with ASD in early childhood center-based settings were discussed.

“…Practical significance involves a value judgment made by the consumer of research about the implications of a set of results and the consequences of a particular decision (Vaske, Gliner, & Morgan, 2002). Practical significance means asking the question of whether the results are noteworthy and whether they are big enough to matter (Armstrong & Henson, 2004). In other words, ''data should be described in a way that fits with how practitioners would describe the situation being addressed in the study'' (Baldridge et al, 2004(Baldridge et al, , p. 1073.…”

In response to the ongoing concern regarding a science-practice gap, we propose a customer-centric approach to reporting significant research results that involves a sequence of three interdependent steps. The first step involves setting an alpha level (i.e., a priori Type I error rate) that considers the relative seriousness of falsely rejecting a null hypothesis of no effect or relationship (i.e., Type I error) relative to not detecting an existing effect or relationship (i.e., Type II error) and reporting the actual observed p value (i.e., probability that the data would be obtained if the null hypothesis is true). The second step involves reporting estimates of the size of the effect or relationship, which indicate the extent to which an outcome is explained or predicted. The third step includes reporting results of a qualitative study to gather evidence regarding the practical significance of the effect or relationship. Our proposal to report research results with rigor, relevance, and practical impact involves important changes in how we report research results with the goal to bridge the science-practice gap.
