Effectiveness of a Single Prolonged Aerobic Exercise Session on Executive Function Task Performance in Physically Active Adults (21–70 Years of Age)

Description: Authors of the article sought to examine the effectiveness of an acute prolonged exercise session on post-exercise executive function in physically active adults and to assess if age or pre-exercise cognitive performance was predictive of the magnitude of change in executive task performance. Their results support the effectiveness of a single prolonged exercise bout to augment executive function in physically active adults, irrespective of age.

Homologues and homology and their related terms in phylogenetic systematics

Description: Article describes how, in the field of phylogenetic systematics, the terms homology and homologue and their relationship to cladistic terms such as character, character state, synapomorphy and symplesiomorphy, as well as their relationships to each other, have been and are still discussed frequently. A recent re-emergence of concepts of homology/homologue free of any reference to explanatory hypotheses prompted the authors to explore these concepts and their relationships to each other as well … more

Modulating Uranium Extraction Performance of Multivariate Covalent Organic Frameworks through Donor–Acceptor Linkers and Amidoxime Nanotraps

Description: Article presents a COF (covalent organic framework)-based adsorption-photocatalysis strategy for selective removal of uranyl from seawater in the absence of sacrificial reagents. This work shows that multivariate COF adsorption-photocatalysts can be rationally engineered to work efficiently and stably without sacrificial electron donors, thus opening the pathway for the economic and efficient extraction of uranium from the earth’s oceans.

Strategic choice in times of stagnant growth and uncertainty: An institutional theory and organizational change perspective

Description: Article provides insight into the strategic behaviors of firms facing slow growth in times of economic stagnation. Using the pertinent literature from institutional theory and organizational change, the authors posit that the appropriate firm-level response (strategic choice) during periods of slow growth is to maintain legitimacy and membership in the field by adopting a proactive approach that focuses on improving top-line growth.

Expand-and-Randomize: An Algebraic Approach to Secure Computation

Description: This article considers the secure computation problem in a minimal model, where Alice and Bob each holds an input and wish to securely compute a function of their inputs at Carol without revealing any additional information about the inputs. For this minimal secure computation problem, the authors propose a novel coding scheme built from two steps. First, the function to be computed is expanded such that it can be recovered while additional information might be leaked. Second, a randomization s… more

Does Perceived Competence Mediate between Ball Skills and Children’s Physical Activity and Enjoyment?

Description: This article examines the potential mediating role of perceived motor skill competence on relationships between actual ball skills and children’s physical activity (PA) and PA enjoyment. Correlation analyses showed positive relationships among the study variables. The findings highlight that ball skills significantly impact students’ perceived competence, positively and indirectly affecting their PA and PA enjoyment.

Are States Created Equal? Moving to a State With More Expensive Childcare Reduces Mothers' Odds of Employment

Description: This article investigates whether moving to a state with more expensive childcare is associated with lower odds of maternal employment among mothers who had been employed prior to relocation. Results show that moving to states with fewer childcare barriers is associated with higher levels of maternal employment, partly mitigating the negative labor market effects of interstate migration.
