Intelligence in Context: A Context-specific Mindset Measure Better Predicts Outcomes for Science and Math Undergraduates
No full textMindset (beliefs about the malleability of intelligence) has been studied in a variety of contexts for decades. Recent research highlights the importance of contextual factors in moderating mindset’s impact on student outcomes. The commonly-used original mindset measure is context-general. Recently, a mindset measure that is specific to science and math undergraduates was developed: the Undergraduate Lay Theories of Abilities (ULTrA) Survey. I hypothesized that a context-specific measure of mindset would associate more strongly with undergraduates’ outcomes than a context-general measure. I surveyed 1537 undergraduates with Dweck’s 3-item original mindset measure, ULTrA, and measures of outcomes (sense of belonging, goal orientation, self-handicapping, evaluative concern and intent to persist in science) and collected course grades. Structural equation modeling indicated that the fixed factor of the ULTrA exhibited stronger and more consistent relationships with outcomes than the 3-item original mindset measure and predicted unique variance in outcomes above and beyond what the original mindset measure accounted for. The academic outcomes (intent to persist and course grade) were significantly related to ULTrA, but not the original mindset measure. Our results provide evidence that the context-specific ULTrA survey can detect relationships with undergraduate outcomes that the context-general original mindset measure can fail to detect

The Sub 2-h Official Marathon is Possible: Developing a Drafting Strategy for a Historic Breakthrough in Sports
No full textBackground
Drafting for drag reduction is a tactic commonly employed by elite athletes of various sports. The strategy has been adopted by Kenyan runner Eliud Kipchoge on numerous marathon events in the past, including the 2018 and 2022 editions of the Berlin marathon (where Kipchoge set two official world records), as well as in two special attempts to break the 2 h mark for the distance, the Nike Breaking2 (2017) and the INEOS 1:59 Challenge (2019), where Kipchoge used an improved drafting formation to finish in 1:59:40, although that is not recognized as an official record.
Results
In this study, the drag of a realistic model of a male runner is calculated by computational fluid dynamics for a range of velocities. The formations employed in the past by Kipchoge, as well as alternative formations, are analyzed and systematically compared with respect to mechanical power. In a quest to show that running an official marathon in under 2 h is possible, the power analysis is extended to the pacers. We developed a simple drafting and pacing strategy that Kipchoge could have used to run the 2022 Berlin marathon in a surprising 1 h, 59 min and 48 s.
Conclusions
Elite marathon runners can make better use of the pacers to experience reduced drag in races. The associated energy reduction makes it possible to run faster, finishing the race in less time. Using a better drafting strategy and a positive splitting pacing strategy, Kenyan runner Eliud Kipchoge could have broken the sub 2 h barrier in both the 2018 and 2022 editions of Berlin Marathon
