Statistical mediation and moderation analysis are widespread throughout the behavioral sciences. Increasingly, these methods are being integrated in the form of the analysis of ―mediated moderation‖ or ―moderated mediation,‖ or what Hayes and Preacher (in press) call conditional process modeling. In this paper, I offer a primer on some of the important concepts and methods in mediation analysis...

Given that age is considered a key demographic variable for IS research, recent work has accumulated overwhelming evidence that older workers perform worse on computerized tasks than their younger counterparts. This finding is alarming given the facts that the workforce is rapidly growing older and, at the same time, organizational technologies are proliferating. However, the reasons for the fi...

The current research drew upon the resource perspective (Grzywacz & Marks, 2000; ten Brummelhuis & Bakker, 2012) and firstly focused on the reciprocal mediation relationship between schedule control, work interference with family (WIF) and emotional exhaustion. First, the present study proposed that WIF mediates the negative relationship between schedule control and emotional exhaustion, and em...

In chemistry, lack of academic preparation and math ability have been offered as explanations as to why women seem to enroll, perform, and graduate at lower levels than men. In this paper, we explore the alternative possibility that the gender gap in chemistry instead originates from differential gender effects of academic factors on students’ motivation. Using a sample of approximately 670 stu...

The mediational role of worry and practice time in explaining the relationship between implicit theories of ability and performance was examined in two studies. It was hypothesized that holding an implicit theory of ability as fixed and unchangeable would impair test performance. Worry and time invested in practicing prior to taking a test were predicted to mediate the direct effect of implicit...

Most studies about the effects of producers’ services on manufacturing agglomeration focus on the effects themselves while neglecting the mechanism that such effects spread. By stressing the key role of trade costs in the process of manufacturing agglomeration, this paper identifies a chain of effects from producers’ service improvements to manufacturing agglomeration via changing trade costs a...

This research uses a representative sample of U.S. nascent entrepreneurs to find that there is a positive relationship between their use of systematic search and their success in founding new firms. We control for mediating variables and find that searching systematically leverages firm founding by using an adaptive decision making style and social capital. Systematic search also appears to red...

Recent literature on migration and the environment has identified key mediating variables such as how migrants extract resources from the environment for their livelihoods, the rate and efficiency of extraction, and the social and economic context within which their extraction occurs. This paper tests these theories in a new ecological setting using data from coastal fishing villages in North S...

People report solving division problems by mentally recasting division problems as multiplication (e.g., 72 ÷ 8 à 8 × [?] = 72). Mediation of division by multiplication occurs mainly on larger problems. Eye tracking data was used to determine whether patterns of gaze durations on division problems provided support for mediation. Adults solved division problems in two formats: traditional (e.g.,...
