Does Perceived Competence Mediate between Ball Skills and Children’s Physical Activity and Enjoyment? (open access)

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

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.

On Batch-Processing Based Coded Computing for Heterogeneous Distributed Computing Systems (open access)

On Batch-Processing Based Coded Computing for Heterogeneous Distributed Computing Systems

This article focuses on practical computing systems with heterogeneous computing resources, and designs a novel CDC approach, called batch-processing based coded computing (BPCC), which exploits the fact that every computing node can obtain some coded results before it completes the whole task. The scheme demonstrates promising performance in terms of high computational efficiency and robustness to uncertain disturbances.

Numerical Simulation of Fiber Motion in the Condensing Zone of Lateral Compact Spinning with Pneumatic Groove (open access)

Numerical Simulation of Fiber Motion in the Condensing Zone of Lateral Compact Spinning with Pneumatic Groove

This article creates a new fiber model to simulate the agglomeration process, to analyze yarn properties of the lateral compact spinning with pneumatic groove, and to compare with other spinning yarns through a series of tests. The experiments demonstrated that the lateral compact spinning with pneumatic groove can improve the yarn properties: increase the yarn twist, enhance the yarn strength, and reduce the yarn hairiness.

Spatial Targeting of Agricultural Support Measures: Indicator-Based Assessment of Coverages and Leakages (open access)

Spatial Targeting of Agricultural Support Measures: Indicator-Based Assessment of Coverages and Leakages

This article evaluates the targeting strategy of a national-level program in Mexico that distributed agricultural support based on seven criteria that prioritized poor smallholder farming communities at high risk of cropland failure. The findings highlight the continued lack of financial support for smallholder agriculture in Mexico, despite program rules and priority statements that stress the vulnerability of this sector. The article also illustrates the important role of spatial targeting in better aligning agricultural support payments with stated policy priorities.

Structural Modeling and in planta Complementation Studies Link Mutated Residues of the Medicago truncatula Nitrate Transporter NPF1.7 to Functionality in Root Nodules

This article combines in silico structural predictions with in planta complementation of the severely defective mtnip-1 mutant plants to understand the role of a series of distinct amino acids in the transporter’s function. The findings add to the knowledge of the mechanism of alternative conformational changes as well as symport transport in NPFs and enhance knowledge of the mechanisms for nitrate signaling.

Scaling of axial muscle architecture in juvenile Alligator mississippiensis reveals an enhanced performance capacity of accessory breathing mechanisms

Article describing the anatomy of the trunk muscles, their properties that determine muscle performance (mass, length and physiological cross-sectional area [PCSA]) and investigating their scaling in juvenile Alligator mississippiensis spanning an order of magnitude in body mass (359 g–5.5 kg).

A Comprehensive Approach to Addressing Gender Equity in STEM Subjects at Four-Year Universities in England (open access)

A Comprehensive Approach to Addressing Gender Equity in STEM Subjects at Four-Year Universities in England

This chapter explores gender disparities in enrollment and persistence in STEM undergraduate education in England. The authors examine the difference in early educational achievement in mathematics and science subjects and students’ plan to study STEM subjects by gender. They also examine women’s odds of studying STEM subjects in England after controlling for academic performance and social class characteristics. The authors also particularly test gendered differences in studying STEM at prestigious Russell Group universities. Finally, the authors highlight factors that policy makers, researchers, instructors, and STEM workforce members should consider to close gender gaps in STEM undergraduate education.

STEM Bachelor's Degree Attainment among Women of Color in the United States: Using Geographic Analysis for Gender and Racial Equity Research (open access)

STEM Bachelor's Degree Attainment among Women of Color in the United States: Using Geographic Analysis for Gender and Racial Equity Research

This chapter showcases a study that examines the relationship between STEM bachelor’s degree attainment, particularly focusing on women of color, and the opportunities of higher education and STEM higher education within local communities across the United States. The authors analyze two large-scale national data sets, the Integrated Postsecondary Education Data System (IPEDS) and the American Community Survey (ACS), to conduct a location-level analysis. The authors then offer implications that target women of color who live in places that lack opportunities in higher education.

Introduction: Gender Equity in STEM in Higher Education: International Perspectives on Policy, Institutional Culture, and Individual Choice

This introduction presents an overview of the key concepts discussed in the subsequent chapters of this book. The book provides an international overview of access and success for women in Science, Technology, Engineering, and Mathematics (STEM) undergraduate programs. It focuses on women’s share of STEM graduates to explore trends and compare women’s enrollment in STEM to men’s enrollment in STEM and to higher education in general. The book focuses on the expansion of higher education in Taiwan as it relates to the improved participation of women in STEM tertiary education and in the STEM labor market. It focuses on the persistence of gender inequality in undergraduate engineering education in Germany by analyzing individual factors that contribute to women’s tendency to consider but then opt out of engineering. The book describes several challenges to gender-based equity in STEM in a post-Soviet context and offer multiple policy suggestions for improvement.

The Timeline and Events of the February 2021 Texas Electric Grid Blackouts (open access)

The Timeline and Events of the February 2021 Texas Electric Grid Blackouts

This report recounts the factors contributing to the disruptions in electricity and natural gas service in Texas during Winter Storm Uri, with a particular focus on the outages in electrical service in the Electric Reliability Council of Texas (ERCOT) power region during the period from February 15-18, 2021. In pursuing this report’s objective, the Energy Institute at the University of Texas at Austin assembled a team of faculty and researchers to identify and review credible sources of data in an attempt to provide a factual account of what happened and what went wrong during the winter storm. The report provide recommendations, but to create a common basis of fact to educate the debate over policy changes under consideration as a response to the winter storm. The report specifically limited the scope of this report to the events and economic impacts of February 2021, including a comparison to previous winter storm blackouts of 1989 and 2011. To provide additional historical context, the report include an appendix that describes the long-term evolution of the ERCOT electricity market. This report is not intended to comprehensively address all issues stemming from such a complex event, but can inform future assessments.
