Background: High school graduates live six to nine years longer than high school dropouts. Those with less education are more likely to die prematurely of cardiovascular disease, cancer, infectious disease, diabetes, lung disease, and injury than those with more education. Although there is growing evidence that the education-health relationship is causal, and some mechanisms linking education ...

Background/Context: College grades can influence a student’s graduation prospects, academic motivation, postgraduate job choice, professional and graduate school selection, and access to loans and scholarships. Despite the importance of grades, national trends in grading practices have not been examined in over a decade, and there has been a limited effort to examine the historical evolution of...

Background/Context: Faced with rapidly changing demographics, districts are increasingly looking to partner with parents to support and improve student learning. Community organizing holds promise for pursuing educational equity through the development of low-income parent participation and leadership, but previous research has focused primarily on the use of structural social capital theory in...

To assess, from flight crew perspectives, the benefits and limits of a new spacing instruction, a pilot-in-the-loop experiment was conducted. Beyond assessing interface usability and overall feasibility, the experiment aimed at analysing the impact of various tolerance margins on flight crew activity. Flight crew feedback was generally positive. Despite a new task in the cockpit, which requires...

Behavioural studies have implicated both female choice of mates and male competition for access to mates as proximate mechanisms of sexual selection. Few studies have examined the interactions between these mechanisms in a natural setting. In this study, I explored how dominance interactions between male boat-tailed grackles, Quiscalus majordetermine the mating success of males and how the beha...

Memory is better when repeated learning events are spaced than when they are massed (spacing effect), as well as when material is processed semantically than when it is processed graphemically (levels-of-processing effect). Examination of the relationship between levels of processing and spacing for both deeply and shallowly encoded items has shown a spacing effect for items processed deeply, b...
