Knowledge development and restructuring in the domain of medicine: The role of theory and practice

How does the knowledge of the medical student, clerk, intern, and registrar develop and how do formal and informal, classroom and experiential learning contribute to this process? These questions were investigated in two experiments, focusing on knowledge restructuring rather than knowledge acquisition. The experiments showed that practical experience plays an important role in knowledge restructuring. The process was, however, not as continuous as was expected. Notably, advanced students appeared to have considerable knowledge about conditions in patients and their environments that can predispose to disease. However, they rarely applied it in clinical reasoning. Contrary to what was found in expert physicians, advanced students' knowledge about enabling conditions seems not yet to be integrated into their other knowledge about diseases.     

Building teacher capacity for implementing curricular coherence: mathematics teacher professional development tasks

Improving mathematics education in the United States has taken many forms. Our work has focused on two aspects: the content knowledge of teachers and a well-articulated coherent curriculum. Our aim was teacher “capacity building” that is enabling teachers to teach to coherent and significant mathematical curricular goals and describe the implementation in a large-scale project based at Michigan State University. We highlight the design, structure and use of mathematics teacher learning tasks that were intended to improve teachers’ capacity to teach to these goals and note how the teachers’ perceptions of the structure and sequencing of mathematics itself affect the ways they organize mathematics in their teaching and the ways they teach.     

Two for the price of one?: Additionality effects of R&D subsidies: A comparison between Flanders and Germany

We empirically test whether public R&D subsidies crowd out private R&D investment in Flanders and Germany, using firm level data from the Flemish and German part of the Community Innovation Surveys (CIS III and IV). Both the non-parametric matching estimator and the conditional difference-in-differences estimator with repeated cross-sections (CDiDRCS) clearly indicate that the crowding-out hypothesis can be rejected: funded firms are significantly more R&D active than non-funded firms. In the domain of additionality effects of R&D subsidies, this paper is the first to apply the CDiDRCS method.     

Inhibitory control,dyadic social behavior,and mental health difficulties in preschoolers

Although inhibitory control is typically associated with positive outcomes, several theoretical frameworks suggest that too little and too much inhibitory control may be problematic. Using a longitudinal, latent variable approach, we examined whether a multi-method index of inhibitory control at Time 1 (N = 105, 52 girls, M_age = 3.50 years, 87% White) predicted observed social behavior with an unfamiliar peer and maternal report of preschoolers’ mental health difficulties at Time 2 (M_age = 4.76 years). Data collection occurred between 2017 and 2019. Inhibitory control displayed a U-shaped relation with prospective outcomes, where high and low levels of inhibitory control were associated with higher levels of avoidant social behaviors and mental health difficulties. The results are discussed in the context of under- and over-regulation in understanding individual differences in children's social behavior and mental health difficulties.     

Which worked better for Mississippi State: standing orders or an approval plan?

When Mississippi State University Libraries established a university press approval plan, the Collection Development Department was asked to decide whether to cancel existing standing orders with seven university presses or block these presses from the approval plan. Books were received through both avenues for eight months so that cost, timeliness of delivery, and receipt of titles most appropriate for the Libraries’ needs could be compared. Findings showed a 4.72% cost savings with the approval plan, but 82% of the titles were received earlier through the standing orders. Of books received through the standing orders, 29% were not received through the approval plan, with more than half not matching departmental profiles. Return privileges with the approval plan meant unsuitable titles could be returned, a significant advantage not possible with the standing orders. As a result of the study, the libraries chose to cancel the standing orders and receive books selectively through a university press approval plan.
