How others are involved in interest development

Involvement of other people is beneficial, if not crucial, for adolescents' interest development. Our current understanding of how others can be involved in interest is mostly based on research into a particular kind of interest (e.g., STEM-interests) or particular contexts, most prominently school and hobby/affinity practices. This study explores the ways involvement of others unfolds when adolescents pursue different interests in and across different contexts. We studied all reported interests of nine purposefully selected adolescents over the course of almost three years using experience sampling reports of interest engagement (N = 3029 events) and interviews reflecting on interest pursuits (N = 174). We observed twelve manifestations of involvement during interest engagement, that differ in: (1) whether others were involved in a structural way; (2) who and (3) how involved others are; (4) if their involvement is necessary; and, lastly, (5) whether the interest engagement or involvement of others is foregrounded in adolescents' experience. We identified shifts in the presence of others, how they are involved, and their necessity for interest over time. Involved others appear to be consequential for if and how adolescents pursue their interests. These findings serve as a reminder to anyone concerned with adolescents' interest to be mindful of their own and others' role in adolescents' interest pursuits.</p

Quantification of bone involvement in Gaucher disease: MR imaging bone marrow burden score as an alternative to dixon quantitative chemical shift MR imaging - Initial experience

PURPOSE: To develop a semiquantitative magnetic resonance (MR) imaging bone marrow burden (BMB) score with inclusion of both axial and peripheral bone marrow in Gaucher disease as an alternative to MR imaging with the Dixon quantitative chemical shift imaging (QCSI) technique.MATERIALS AND METHODS: Two experienced musculoskeletal radiologists with no experience in evaluating Gaucher disease blindly analyzed MR images of lumbar spines and femora. Interobserver and intraobserver variability were tested. In addition, the BMB score was determined as a parameter to evaluate bone marrow response to enzyme supplementation therapy. Finally, the BMB score was compared with fat fraction measurements obtained with Dixon QCSI. Differences between groups were analyzed by using the nonparametric Mann-Whitney test. A P value of less than .05 was considered to represent significance. Correlation was calculated by using two-tailed nonparametric rank correlation (Spearman ρ).RESULTS: In 30 patients (mean age, 39.3 years; age range, 12–71 years) the mean fat fraction was 0.20 (range, 0.08–0.40). The BMB score range was 3–13 points. A significant correlation was found between the two observers when using BMB (ρ = 0.91, P P P CONCLUSION: BMB is a reproducible semiquantitative scoring system that is easy to use. It combines MR imaging of both axial and peripheral bone marrow and shows a significant correlation with QCSI.FWN – Publicaties zonder aanstelling Universiteit Leide
