Whose banner are we waving? Exploring STEM partnerships for marginalized urban youth

This case study examines after school programming in citizen science from the perspective of Critical Race Theory. During the course of enacting community outreach projects this data was used to examine the positioning of experts, student, and teachers within the program. This study explores the role of race and ethnicity, and the ways in which marginalization can manifest itself with black urban youth and teachers. Implications for partner selection and training are addressed.     

Predicting Physical Activity Among Children: Investigating Interaction Effects in the Theory of Planned Behavior

ABSTRACT

Purpose: The theory of planned behavior (TPB) has been criticized for not including interactions between the variables assumed to predict behavior. This study sought to test how TPB variables interact to predict physical activity (PA) in children. Method: Four hundred thirty-eight children (M_age = 8.6 years, SD = 1.6 years) completed a TPB questionnaire and a PA questionnaire at Time 1. The PA measure was repeated 2 months later. Path analyses were performed to test the hypothesized model including interaction terms between TPB variables. Simple slopes analyses were also carried out to examine the statistically significant interaction terms. Results: Path analyses confirmed the classical hypotheses of TPB (R² for intentions = .39, R² for PA = .12) and also demonstrated only statistically significant Attitudes × Perceived Behavioral Control and Subjective Norms × Attitudes interactions (R² change for intentions = .01, p = .009). Simple slopes analyses revealed that the strength of the association between perceived behavioral control and intentions was only statistically significantly higher (t = 2.18, p = .05, d = 0.34, 95% CI [0.03, 0.65]) when attitudes were high compared with when attitudes were low. The link between attitudes and intentions was only statistically significant at a low level of subjective norms but not at a high level. Conclusion: The integration of interaction effects between TPB variables did not increase for the variance of PA explained by the model. More research appears to be necessary to explore how the TPB could be augmented to better predict PA in children.     

Cogenerated understandings of mindfulness-based breathing in elementary mathematics classrooms

Bringing an awareness of emotions to the fore through mindfulness-based breathing and providing a space to discuss them is a way of promoting teacher and student agency in collectively developing structures specific to their learning environment. The authors explore students', teachers', and researchers' collective sensemaking through cogenerative dialoguing (cogen) about a mindfulness-based breathing practice at the start of mathematics lessons in an elementary classroom. They found that the power of cogen as hybridized space enabled the generation of collective understanding and the potential for all cogen participants to become engaged in an authentic and transformative way in discussing classroom life. The authors argue that the mindfulness-based breathing practice itself acted as a heuristic for thinking about learning environments and, during the reflexive process of thinking about the breathing practice, new forms of classroom culture unfolded both expanding classroom structures and the practice itself, and laying bare otherwise taken-for-granted practices.

Is home visiting an effective strategy? A meta-analytic review of home visiting programs for families with young children

Home visiting programs for families with young children have been in effect for many years; however, this is the first comprehensive meta-analytic effort to quantify the usefulness of home visits as a strategy for helping families across a range of outcomes. Sixty home visiting programs contributed data to analysis within 5 child and 5 parent outcome groups. Standardized effect sizes were computed for each end-of-treatment outcome measure, for each treatment versus control contrast. Weighted mean standardized effect sizes ranged from -.043 to.318; 6 of the 10 significantly differed from 0. No one program characteristic consistently affected effect sizes across outcome groups. The extent to which these findings have practical use for the field is discussed.     

Assessing Library Customer Interactions and Staff Satisfaction

In 2016, two service departments–the office of information technology (OIT) and the academic resource center (ARC) at the college–physically relocated into the library. To ensure consistent customer service and staffing for the ARC, OIT, and library, the departments collaborated to discuss the implications for their new shared space. They decided to use a common online customer service form in Qualtrics to track and assess library customer interactions and staff satisfaction.     

Caffeine use in a Super Rugby game and its relationship to post-game sleep

Objective: To examine the relationship between regular game-related caffeine consumption on sleep after an evening Super Rugby game. Methods: Twenty elite rugby union players wore a wrist-activity monitor to measure sleep for three days before, three days after and on the night of an evening Super Rugby game (19:00–21:00). Players ingested caffeine as they would normally (i.e. before and sometimes during a game) and saliva samples were collected before (17:00) and after (21:30) the game for caffeine concentration. Results: Compared to the nights leading up to the game, on the night of the game, players went to bed 3?h later (23:08?±?66?min vs 02:11?±?114?min; p?p?p?p?p?p?=?.06) on game night. Conclusion: Caffeine consumption before a Super Rugby game markedly increases post-game saliva caffeine levels. This may contribute to the observed 3.5?h delay in time at sleep onset and the 1.5?h reduction in sleep duration on the night of the game. This study highlights the need for a strategic approach to the use of caffeine within a Super Rugby team considering the potential effect on post-game sleep.
