The Effects of a 6-Week Swimming Intervention on Gross Motor Development in Primary School Children

(1) Background: This study examines the effects of a 6-week swimming intervention on motor competence in children. (2) Methods: A total of 107 children (n = 52 boys, n = 55 girls) aged 7.8 ± 0.63 years that were recruited from five primary schools in central England participated in this study, undertaking either an aquatic intervention once a week for six weeks or acting as a control group completing their usual physical education program. Participants underwent pre- and post-assessments of general motor competence using the Test of Gross Motor Development, Third Edition (TGMD-3) (a process measure) and a composite of 10 m running sprint time and standing long jump distance (product measures). Aquatic motor competence was assessed via the Aquatic Movement Protocol (AMP). Fear of drowning and swimming opportunities were also assessed by implementing a questionnaire. (3) Results: Following a mixed-model ANOVA, an overall main effect was found from pre (40.05 ± 13.6) to post (48.3 ± 18.6) for TGMD-3 scores (p < 0.05) and pre (38.7 ± 31.7) to post (50.6 ± 36.8) for AMP scores (p = 0.001). A negative significant relationship was found between AMP scores with both fear of water (p = 0.01) and fear of drowning (p < 0.05). A positive significant relationship was found between swimming opportunities and AMP score (p = 0.001). (4) Conclusions: The aquatic-based intervention improves not only aquatic motor competence but also transfers improvements in dryland movement competencies. Future research should look to implement control groupings which do not participate in swimming to further investigate the difference between swimmers and non-swimmers; however, due to swimming being a part of the national curriculum in England, this may not be feasible

Older age as a time to contribute: A scoping review of generativity in later life

Research on later-life generativity has promoted a new view of older persons that, far from the traditional images of disability, dependence and frailty, recognises their capacities, and potential to continue growing, while underlining their participation and contributions to families, communities and society. The goal of this study was to carry out a scoping review on later-life generativity, the first one conducted on this topic as far as we know, to show how studies in this area have evolved, which aspects of generativity in later life have been studied, and the methodological and epistemological approaches that are dominant in this area of inquiry. Our scoping review shows that research into generativity in later life has grown steadily over the past 30 years, and particularly during the last decade. However, our results also show how such growing interest has focused on certain methodological approaches, epistemological frameworks and cultural contexts. We identify four critical gaps and leading-edge research questions that should be at the forefront of future research into generativity in later life, gaps that reflect biases in the existing literature identified in the study. These are classified as methodological, developmental, contextual and 'darkside' gaps

The Longitudinal Influence of Parenting and Parents’ Traces on Narrative Identity in Young Adulthood

This longitudinal follow-up studied continued effects of parental influences on narrative identity in young adulthood. Decades of research have shown the importance of parental shared reminiscing and positive parenting for the development of children\u27s and youths\u27 autobiographical memory and narrative identity. Yet, research on long-term influences of parenting on narrative indices in adulthood is scarce, even though parents\u27 traces remain a part of narrative identity throughout the life span (Köber & Habermas, 2018). Therefore, in this study, 118 individuals (at time 1: Mage = 17.3 years, SD = .77, 73% female, 82% White) reported at age 17 on their perceived positive parenting. As emerging and young adults, as part of follow-ups at ages 26 and again at 32, participants provided life story interviews. First, it was tested whether earlier positive parenting longitudinally predicted parents\u27 traces in later life stories. Second, we studied the joint long-term prediction of parenting and parents\u27 traces to several narrative features of these young adults\u27 life stories, including emotional tone, coherent positive resolution, and narrative complexity. Results replicated prior research on parents\u27 traces and showed moreover that perceived parenting shape offspring\u27s narrative identity well into young adulthood. These long-term findings are consistent with the notion that narrative identity in adulthood is rooted in the family, and continuously shaped by experiences with parents.

The X-ray Properties of Optically Selected Clusters of Galaxies

We present the results of Chandra and Suzaku X-ray observations of nine moderate-redshift (0.16 < z < 0.42) clusters discovered via the Red-sequence Cluster Survey (RCS). Surface brightness profiles are fitted to beta models, gas masses are determined, integrated spectra are extracted within R2500, and X-ray temperatures and luminosities are inferred. The Lx-Tx relationship expected from self-similar evolution is tested by comparing this sample to our previous X-ray investigation of nine high-redshift (0.6 < z < 1.0) optically selected clusters. We find that optically selected clusters are systematically less luminous than X-ray selected clusters of similar X-ray temperature at both moderate and high-z. We are unable to constrain evolution in the Lx-Tx relation with these data, but find it consistent with no evolution, within relatively large uncertainties. To investigate selection effects, we compare the X-ray properties of our sample to those of clusters in the representative X-ray selected REXCESS sample, also determined within R2500. We find that while RCS cluster X-ray properties span the entire range of those of massive clusters selected by other methods, their average X-ray properties are most similar to those of dynamically disturbed X-ray selected clusters. This similarity suggests that the true cluster distribution might contain a higher fraction of disturbed objects than are typically detected in X-ray selected surveys.Comment: 13 pages, 5 figures; accepted for publication in MNRAS.

The supraclavius muscle is a novel muscular anomaly observed in two cases of thoracic outlet syndrome

Various anomalous muscles and fibrofascial structures have been described in relation to the anatomy of thoracic outlet syndrome. We describe two patients with a previously undescribed muscle anomaly, which originated laterally near the trapezius muscle, coursed across the supraclavicular space deep to the scalene fat pad, and attached obliquely to the superior undersurface of the medial clavicle, which we have termed the “supraclavius” muscle. The significance of the supraclavius muscle is unknown, but its occurrence in patients with thoracic outlet syndrome indicates that it can be associated with narrowing of the anatomic space adjacent to the neurovascular structures

Topographic control of asynchronous glacial advances: A case study from Annapurna, Nepal

Differences in the timing of glacial advances, which are commonly attributed to climatic changes, can be due to variations in valley topography. Cosmogenic 10Be dates from 24 glacial moraine boulders in 5 valleys define two age populations, late-glacial and early Holocene. Moraine ages correlate with paleoglacier valley hypsometries. Moraines in valleys with lower maximum altitudes date to the lateglacial, whereas those in valleys with higher maximum altitudes are early Holocene. Two valleys with similar equilibrium-line altitudes (ELAs), but contrasting ages, are \u3c 5 km apart and share the same aspect, such that spatial differences in climate can be excluded. A glacial mass-balance cellular automata model of these two neighboring valleys predicts that change from a cooler-drier to warmer-wetter climate (as at the Holocene onset) would lead to the glacier in the higher altitude catchment advancing, while the lower one retreats or disappears, even though the ELA only shifted by ~120 m
