One schooling sector that had been growing before the pandemic, hybrid schools, in which students attend physical classes fewer than five days per week and are homeschooled on the other days, has seen recent continued growth. One factor that has not been explored is the commuting patterns families follow to use these schools. Whether families…

We explore the relations between the notion of distance and a feature set--based concept of similarity and show that this concept of similarity has a spatial interpretation that is complementary to distance: it is interpreted as "direction." Furthermore, we show how proper normalization leads to distances that can be directly interpreted…

In this paper, we present a physical modeling activity whose objective is to allow students to determine the differences between a disk and a sphere using pure scientific criteria. Thereunto, we reproduce the Sun-Earth-Moon system with low-cost materials and compare the illumination effects on the Moon considering two possible shapes for it (a…

In this work we describe a teaching proposal to calculate the eccentricity of the Moon's trajectory by applying a geometrical technique. The values of the ratios between the Earth-Moon distance and the diameter of the Moon at apogee and at perigee were calculated from a kinematic model associated with a geometrical technique of image analysis. The…

Supermarkets located near schools influence adolescents' food consumption. The aims of this study were: (1) to measure dietary behaviors during school hours; (2) to investigate the effect of a nutrition peer-education intervention in supermarkets within walking distance to secondary schools on nutritional knowledge and attitudes toward healthy…

The question of why postsecondary institutions produce different labor market outcomes is difficult to answer due to unobserved student characteristics. Here, I leverage students' geographic proximity to three classifications of postsecondary institutions -- earnings-enhancing, competitive, and Historically Black Colleges and Universities (HBCUs).…

Introduction: This study examined the concurrent validity and inter-pair reliability of the proximity detection function on Bluetooth-enabled accelerometers across manufacturer-specified ranges. If valid, this method could be used for objectively measuring shared physical activity participation. Method: Thirty-six dyads aged 21.6 (2.1) years wore…

This study analyzes the effect of spatial competition on public schools' efficiency in Chile, an extreme case of market-oriented reforms in the educational sector. To address this issue, we use a measure of competition that captures three major characteristics of market competition in a spatial context: the number of competitors, based on distance…

What drives parents to decide to send their children to a particular type or stream of schooling over another? Existing literature suggests that parents take several factors into account while making their children's school choice: the academic reputation of the school, the distance between the child's home and school, a stronger focus on…

To harness the complexity of their high-dimensional bodies during sensorimotor development, infants are guided by patterns of freezing and freeing of degrees of freedom. For instance, when learning to reach, infants free the degrees of freedom in their arm proximodistally, that is, from joints that are closer to the body to those that are more…

COVID-19 forced universities to engage in rapid improvisation and adoption of online learning and teaching. This paper explores "real-time blended" learning in which online students are taught simultaneously with students who are experiencing proximate learning. Two cliques could develop with those learning online becoming observers…

Learning with hands-on experiments can be supported by providing essential information virtually during lab work. Augmented reality (AR) appears especially suitable for presenting information during experimentation, as it can be used to integrate both physical and virtual lab work. Virtual information can be displayed in close spatial proximity to…

In these three studies, I analyze data from the Maryland Longitudinal Data System (MLDS) to investigate how labor markets for early-career music teachers are related to the ongoing music teacher shortage in Maryland. In the first study, I explore the transition from postsecondary graduation into the public-school music teacher workforce. In the…

Introduction: The current study aimed to investigate the psychological impact of the Turkey 2023 earthquakes on children with autism spectrum disorder (ASD) and their parents residing in Hatay, Sanliurfa, and Ankara provinces, encompassing the periods both before and after the Turkey 2023 earthquakes. Method: This cross-sectional, multicenter…

Recent semantic space models learn vector representations for word meanings by observing statistical redundancies across a text corpus. A word's meaning is represented as a point in a high-dimensional semantic space, and semantic similarity between words is quantified by a function of their spatial proximity (typically the cosine of the angle…
