The roles of readiness and dosage in predicting outcomes of a mindful sport performance enhancement intervention with U.S. college student-athletes.

Research suggests that Mindfulness- and Acceptance-Based Interventions (MABIs) can impact sport performance and performance-relevant factors, though questions remain regarding when and for whom MABIs are effective. Specifically, inquiries into intervention engagement (i.e.

Speaking two "Languages" in America: A semantic space analysis of how presidential candidates and their supporters represent abstract political concepts differently.

In this article we report a computational semantic analysis of the presidential candidates' speeches in the two major political parties in the USA. In Study One, we modeled the political semantic spaces as a function of party, candidate, and time of election, and findings revealed patterns of differences in the semantic representation of key political concepts and the changing landscapes in which the presidential candidates align or misalign with their parties in terms of the representation and organization of politically central concepts. Our models further showed that the 2016 US presidential nominees had distinct conceptual representations from those of previous election years, and these patterns did not necessarily align with their respective political parties' average representation of the key political concepts.

The mediating role of metacognition in the relationship between executive function and self-regulated learning.

Background: Researchers have demonstrated significant relations among executive function, metacognition, and self-regulated learning. However, prior research emphasized the use of indirect measures of executive function and did not evaluate how specific executive functions are related to participants' self-regulated learning.

Aims: The primary goals of the current study were to examine and test the relations among executive function, metacognition, and self-regulated learning as well as to examine how self-regulated learning is informed by executive function.

Design and biocompatibility of endovascular aneurysm filling devices.

The rupture of an intracranial aneurysm, which can result in severe mental disabilities or death, affects approximately 30,000 people in the United States annually. The traditional surgical method of treating these arterial malformations involves a full craniotomy procedure, wherein a clip is placed around the aneurysm neck. In recent decades, research and device development have focused on new endovascular treatment methods to occlude the aneurysm void space.

Differences in oxygen-dependent nitric oxide metabolism by cytoglobin and myoglobin account for their differing functional roles.

The endogenous vasodilator nitric oxide (NO) is metabolized in tissues in an oxygen-dependent manner. In skeletal and cardiac muscle, high concentrations of myoglobin (Mb) function as a potent NO scavenger. However, the Mb concentration is very low in vascular smooth muscle, where low concentrations of cytoglobin (Cygb) may play a major role in metabolizing NO.

Characterization of the function of cytoglobin as an oxygen-dependent regulator of nitric oxide concentration.

The endogenous vasodilator nitric oxide (NO) is metabolized in tissues in an O(2)-dependent manner. This regulates NO levels in the vascular wall; however, the underlying molecular basis of this O(2)-dependent NO consumption remains unclear. While cytoglobin (Cygb) was discovered a decade ago, its physiological function remains uncertain.

Application of carbon fiber composite minielectrodes for measurement of kinetic constants of nitric oxide decay in solution.

Carbon fiber microelectrodes and carbon fiber composite minielectrodes (CFM/CFCM) have been generally used for measurements of nitric oxide (NO) concentration in chemical and biological systems. The response time of a CFM/CFCM is usually from milliseconds to seconds depending on the electrode size, the thickness of coating layers on the electrode, and NO diffusion coefficients of the coating layers. As a result, the time course of recoded current changes (I-t curves) by the CFM/CFCM may be different from the actual time course of NO concentration changes (c-t curves) if the half-life of NO decay is close to or shorter than the response time of the electrode used.
