Measurement precision of body composition variables in elite wheelchair athletes,using dual-energy X-ray absorptiometry

The purpose of this study was to assess the reproducibility of body composition measurements by dual-energy X-ray absorptiometry (DXA) in 12 elite male wheelchair basketball players (age 31 ± 7 years, BMI 21 ± 2 kg/m² and onset of disability 25 ± 9 years). Two whole body scans were performed on each participant in the supine position on the same day, using Lunar Prodigy Advance DXA (GE Lunar, Madison, WI, USA). Participants dismounted from the scanning table and were repositioned in-between the first and second scan. Whole body coefficient of variation (CV) values for bone mineral content (BMC), fat mass (FM) and soft tissue lean mass (LTM) were all <2.0%. With the exclusion of arm FM (CV = 7.8%), CV values ranged from 0.1 to 3.7% for all total body and segmental measurements of BMC, FM and LTM. The least significant change that can be attributed to the effect of treatment intervention in an individual is 1.0 kg, 1.1 kg, 0.12 kg for FM, LTM, and BMC, respectively. This information can be used to determine meaningful changes in body composition when assessed using the same methods longitudinally. Whilst there may be challenges in the correct positioning of an individual with disability that can introduce greater measurement error, DXA is a highly reproducible technique in the estimation of total and regional body composition of elite wheelchair basketball athletes.     

Opening Doors: Teaching LGBTQ-themed Young Adult Literature for an Inclusive Curriculum

LGBTQ themes are often neglected in many schools' curriculum. Currently, an LGBTQ-inclusive curriculum framework is not required in most school districts across the county. Therefore, it is important to understand how teachers regard LGBTQ issues; how they address the needs of students in the middle school and high school English classroom who identify on this spectrum or who come from LGBTQ families; and how they incorporate literature that may be considered “controversial” in their future school districts. In this study, English/Language Arts preservice teachers (PSTs) (certification 7–12) were invited to participate in a book club and self-select young adult (YA) literature centering on characters who identify on the LGBTQ spectrum. During two book club meetings, three themes emerged that embody how literature can become a mirror as well as a window for students and assist youth in identity formation and confirmation. Moreover, literature has the potential to empower readers to take action on controversial issues, especially when readers are in positions to make change (no matter how subtle). Although the data collected were from PSTs, our aim with this article is to expand these three themes as overarching messages for practicing educators today, urging the importance of a more inclusive curricula involving LGBTQ literature.     

Coping With the Unexpected in Childbirth: A Thematic Analysis

This article reports original research that describes new mothers'' experiences of birth and maternity care. Qualitative data were collected through a survey on birth satisfaction, which included space for women to provide comments about their birth and experience of care. Thirty-nine women provided comments that were analyzed using the thematic analysis method. Two themes emerged from the women''s experiences: “Unexpected birth processes: expectations and reality” and “Coping with birth: the role of health-care staff.” Participants described unexpected birthing processes, their experiences of care, and maternity care staff''s contributions to coping with birth. Implications for practice for childbirth professionals include promotion of physiologic birth, respectful person-centered care during all phases of perinatal care, and the value of childbirth preparation.     

Overconfidence produces underachievement: Inaccurate self evaluations undermine students’ learning and retention

The function of accurately monitoring one’s own learning is to support effective control of study that enhances learning. Although this link between monitoring accuracy and learning is intuitively plausible and is assumed by general theories of self-regulated learning, it has not received a great deal of empirical scrutiny and no study to date has examined the link between monitoring accuracy and longer-term retention. Across two studies, college students paced their study of key-term definitions (e.g., “Proactive interference: Information already stored in memory interferes with the learning of new information”). After all definitions were studied, participants completed practice cued recall tests (e.g., “What is proactive interference?”) in which they attempted to type the correct definition for each term. After each test trial, participants judged how much of their response was correct. These study-test-judgment trials continued until a definition was judged as correct three times. A final cued recall test occurred two days later. In Study 1, judgment accuracy was manipulated experimentally, and in Study 2, individual differences in accuracy were examined. In both studies, greater accuracy was associated with higher levels of retention, and this link could not be explained by differential feedback, effort during study, or trials to criterion. Results indicate that many students could benefit from interventions aimed at improving their skill at judging their learning.     

Treatment for Sexual Assault Survivors at University Counseling Centers

University Counseling Centers (UCCs) provide important services for sexual assault survivors, yet little research has been conducted on interventions used by clinicians in this unique setting. As a preliminary investigation, UCC professionals were asked about services provided to survivors of sexual assault and staff perceptions of the effectiveness of these interventions. Supportive counseling was perceived to be the most effective relative to other interventions, and many participants indicated that they did not use or were not sure if other evidence-based interventions were effective with student victims. Several recommendations for future research on sexual assault services in UCCs are suggested.     

Age Differences in use of Strategy for Recall of Movement in a Large Scale Environment

Abstract

In order to investigate how children remember distance (route) and location (landmark) information, two experiments were conducted in a large scale environment using jogging as the means of locomotion. In Experiment 1, thirty 4-year-old and thirty 9-year-old children were randomly assigned within age to three groups which were cued prior to the jog to remember the event, location of the event or distance to the event. Results indicated that older children reproduced the location and distance better than younger children. Cueing children to remember the location resulted in more accurate estimates than the other conditions. In Experiment 2, 5-year-old, 9-year-old, and 12-year-old children (24 children of each age) were randomly divided into step counting strategy and control groups, and asked to reproduce a criterion distance jogged. Results indicated that the three strategy groups and the 12-year-old controls estimated distance with similar accuracy, but the 9- and 5-year-old controls were different, as their error was inversely related to age.     

“American = English Speaker” Before “American = White”: The Development of Children's Reasoning About Nationality

Adults implicitly judge people from certain social backgrounds as more “American” than others. This study tests the development of children's reasoning about nationality and social categories. Children across cultures (White and Korean American children in the United States, Korean children in South Korea) judged the nationality of individuals varying in race and language. Across cultures, 5‐ to 6‐year‐old children (N = 100) categorized English speakers as “American” and Korean speakers as “Korean” regardless of race, suggesting that young children prioritize language over race when thinking about nationality. Nine‐ and 10‐year‐olds (N = 181) attended to language and race and their nationality judgments varied across cultures. These results suggest that associations between nationality and social category membership emerge early in life and are shaped by cultural context.     

Teaching Instructional Design: An Apprenticeship Model

Several cognitive psychologists have written about the importance of placing instruction within “authentic” contexts that mirror real-life situations. They argue that knowledge learned in academic settings does not necessarily transfer to non-academic settings. Whether preparing performance technologists or instructional designers, educators must strive to create meaningful problem-solving contexts that enable students to define, and subsequently solve, real-world problems. In an attempt to address this issue we have modified the way we teach instructional design. This paper discusses a cognitive apprenticeship approach to teaching design, which incorporates elements of modeling, coaching, reflection, articulation, and exploration. We describe how these features are embedded within three phases (orientation, situated training/learning, and exploration) of an introductory instructional design course designed to move our novice designers along a continuum of expertise as they develop and refine their own professional design skills. Although the apprenticeship model described here specifically addresses concerns within the context of preparing instructional designers, we believe that this model can be adapted to address similar issues in the education of performance technologists.
