Research suggests that spatial ability may predict success in complex disciplines including anatomy, where mastery requires a firm understanding of the intricate relationships occurring along the course of veins, arteries, and nerves, as they traverse through and around bones, muscles, and organs. Debate exists on the malleability of spatial ability, and some suggest that spatial ability can be enhanced through training. It is hypothesized that spatial ability can be trained in low-performing individuals through visual guidance. To address this, training was completed through a visual guidance protocol. This protocol was based on eye-movement patterns of high-performing individuals, collected via eye-tracking as they completed an Electronic Mental Rotations Test (EMRT). The effects of guidance were evaluated using 33 individuals with low mental rotation ability, in a counterbalanced crossover design. Individuals were placed in one of two treatment groups (late or early guidance) and completed both a guided, and an unguided EMRT. A third group (no guidance/control) completed two unguided EMRTs. All groups demonstrated an increase in EMRT scores on their second test (P < 0.001); however, an interaction was observed between treatment and test iteration (P = 0.024). The effect of guidance on scores was contingent on when the guidance was applied. When guidance was applied early, scores were significantly greater than expected (P = 0.028). These findings suggest that by guiding individuals with low mental rotation ability “where” to look early in training, better search approaches may be adopted, yielding improvements in spatial reasoning scores. It is proposed that visual guidance may be applied in spatial fields, such as STEMM (science, technology, engineering, mathematics and medicine), surgery, and anatomy to improve student's interpretation of visual content.

The effects of mid-flight whole-body and trunk rotation on landing mechanics: implications for anterior cruciate ligament injuries     

Meghan L. Critchley  Daniel J. Davis  Michaela M. Keener  Jacob S. Layer  Margaret A. Wilson  Qin Zhu 《Sports biomechanics / International Society of Biomechanics in Sports》2020,19(4):421-437

ABSTRACT

The purpose was to quantify the effects of mid-flight whole-body and trunk rotation on knee mechanics in a double-leg landing. Eighteen male and 20 female participants completed a jump-landing-jump task in five conditions: no rotation, testing leg ipsilateral or contralateral (WBRC) to the whole-body rotation direction, and testing leg ipsilateral (TRI) or contralateral to the trunk rotation direction. The WBRC and TRI conditions demonstrated decreased knee flexion and increased knee abduction angles at initial contact (2.6 > Cohen’s dz > 0.3) and increased peak vertical ground reaction forces and knee adduction moments during the 100 ms after landing (1.7 > Cohen’s dz > 0.3). The TRI condition also showed the greatest knee internal rotation angles at initial contact and peak knee abduction and internal rotation angles and peak knee extension moments during the 100 ms after landing (2.0 > Cohen’s dz > 0.5). Whole-body rotation increased contralateral knee loading because of its primary role in decelerating medial-lateral velocities. Trunk rotation resulted in the greatest knee loading for the ipsilateral knee due to weight shifting and mechanical coupling between the trunk and lower extremities. These findings may help understand altered trunk motion in anterior cruciate ligament injuries.  相似文献   

Effects of purposeful soccer heading on circulating small extracellular vesicle concentration and cargo     

Eric R. Muoz  Jaclyn B. Caccese  Brittany E. Wilson  Kyle T. Shuler  Fernando V. Santos  Carolina T. Cabn  John J. Jeka  Dianne Langford  Matthew B. Hudson 《运动与健康科学(英文)》2021,10(2):122

BackgroundConsidering the potential cumulative effects of repetitive head impact (HI) exposure, we need sensitive biomarkers to track short- and long-term effects. Circulating small extracellular vesicles (sEVs) (<200 nm) traffic biological molecules throughout the body and may have diagnostic value as biomarkers for disease. The purpose of this study was to identify the microRNA (miRNA) profile in circulating sEVs derived from human plasma following repetitive HI exposure.MethodsHealthy adult (aged 18–35 years) soccer players were randomly assigned to one of 3 groups: the HI group performed 10 standing headers, the leg impact group performed 10 soccer ball trapping maneuvers over 10 min, and the control group did not participate in any soccer drills. Plasma was collected before testing and 24 h afterward, and sEVs were isolated and characterized via nanoparticle tracking analysis. Next-generation sequencing was utilized to identify candidate miRNAs isolated from sEVs, and candidate microRNAs were analyzed via quantitative polymerase chain reaction. In silico target prediction was performed using TargetScan (Version 7.0; targetscan.org) and miRWalk (http://mirwalk.umm.uni-heidelberg.de/) programs, and target validation was performed using luciferase reporter vectors with a miR-7844-5p mimic in human embryonic kidney (HEK) 293T/17 cells.ResultsPlasma sEV concentration and size were not affected across time and group following repetitive HI exposure. After 24 h, the HI read count from next-generation sequencing showed a 4-fold or greater increase in miR-92b-5p, miR-423-5p, and miR-24-3p and a 3-fold or greater decrease in miR-7844-5p, miR-144-5p, miR-221-5p, and miR-22-3p. Analysis of quantitative polymerase chain reaction revealed that leg impact did not alter the candidate miRNA levels. To our knowledge, miR-7844-5p is a previously unknown miRNA. We identified 8 miR-7844-5p mRNA targets: protein phosphatase 1 regulatory inhibitor subunit 1B (PPP1R1B), LIM and senescent cell antigen-like domains 1 (LIMS1), autophagy-related 12 (ATG12), microtubule-associated protein 1 light chain 3 beta (MAP1LC3B), integrin subunit alpha-1 (ITGA1), mitogen-activated protein kinase 1 (MAPK1), glycogen synthase kinase 3β (GSK3β), and mitogen-activated protein kinase 8 (MAPK8).ConclusionCollectively, these data indicate repetitive HI exposure alters plasma sEV miRNA content, but not sEV size or number. Furthermore, for the first time we demonstrate that previously unknown miR-7844-5p targets mRNAs known to be involved in mitochondrial apoptosis, autophagy regulation, mood disorders, and neurodegenerative disease.  相似文献   

Innovation in a federal state     

Andrew H. Wilson 《Research Policy》1974,2(4):364-379

As a country with a relatively small international reputation for manufacturing and, apparently, with an even smaller one for technology-based product and process innovation in manufacturing, Canada has a long way to go to develop its manufacturing and innovative activities to the stage reached by most European countries. Recently, however, a number of science and research policy studies have been made to examine problems associated with innovation in manufacturing. This present paper deals with two important elements associated with these studies, namely, the organization of the public sector in Canada and the roles and responsibilities of the public sector agencies with regard to the encouragement of technology-based innovation in manufacturing. As pointed out in the paper, the federal structure and the agencies within it may at present frustrate as well as encourage innovation. However, assuming that the appropriate policy objectives can be articulated and accepted, the removal of the principal public sector frustrations will be dependent upon better divisions of responsibility and labour between the three levels of government.  相似文献

Victoria Cardullo  Vassiliki “Vicky” I. Zygouris‐Coe  Nance S. Wilson 《Journal of Research in Reading》2017,40(Z1):S190-S208

The intent of this research was to investigate the experiences of eighth grade readers as they read nonfiction text on an iPad for academic purposes. We investigated reading strategies that students use to support their reading as well as what role iPad features played in the reading process. New literacies, metacognition and transactional theories informed the framework. Multiple data sources were used to triangulate findings and included (a) retrospective think alouds, (b) student iPad survey, (c) pre and post study student interviews, (d) Metacognitive Awareness of Reading Strategies Inventory and (e) student observations. Data for the collective case study participants focused on the identification of proficient readers who displayed confidence, competency, and control over text. Themes identified in the collective case studies included (a) reading comprehension strategies, (b) nonfiction features and (c) iPad features to support their reading of nonfiction on the iPad.  相似文献   

A Fresh Theoretical Perspective on Practice‐Led Research          下载免费PDF全文

Barbara Hawkins  Brett Wilson 《The International Journal of Art & Design Education》2017,36(1):82-91

Practice‐led research in art and design has now come of age and can take its place alongside other forms of research at the academic ‘high table’. It no longer needs to be treated with ‘special consideration’ as a new form of intellectual enquiry. The research craft developed by those involved in practice‐led research admits them to a broader community of practice engaged in questioning the conceptual basis of how we perceive and make sense of the world around us. The objective/subjective divide that preoccupied an earlier generation of academics has eventually been replaced by a more nuanced epistemological framework able to embrace PhDs that include non‐textual artefacts as part of their exposition. An increasing number of academic institutions around the world have taken up the debate and now participate in practice‐led research programmes. However, for early‐career researchers in these fields there are still many hurdles to overcome, some of which are unique to this form of endeavour, as we outline. This article has been developed from a series of seminars and workshops presented by the authors to early‐career practice‐led researchers as part of their Project Dialogue programme which seeks greater engagement between the arts and sciences.  相似文献   

Computer Technology,Science Education,and Students with Learning Disabilities     

Kumar  David  Wilson  Cynthia L. 《Journal of Science Education and Technology》1997,6(2):155-160

The ways computer technology could be used to teach science to students with learning disabilities (LD) are explored. Science is for all students and that includes students with LD. Learning science has both cognitive and affective implications for students with LD. In this context, computer technology provides cognitively engaging and motivating instructional tools for individualizing the mode of delivery; developing expert tutors; anchoring instruction; integrating science with other subjects; reducing cognitive load on working memory; and motivating students to stay on task. These applications are discussed with implications for teaching science to students with LD.  相似文献   

Psychosocial Dynamics of College Students' Use of Mental Health Services     

Beth Spenciner Rosenthal  William Cody Wilson 《Journal of College Counseling》2016,19(3):194-204

The authors present and empirically test a multivariate model of the use of mental health counseling services. Use of such services by 1st‐year college students is directly a result of need for these services and willingness to use them. Beliefs about mental health services and demographic characteristics are not directly related to use, but indirectly affect use by influencing willingness to use. Implications for college counseling programs are discussed.  相似文献   

“Because if we don’t talk about it,how are we going to prevent it?”: Lucidity,a narrative-based digital game about sexual violence

This paper describes the development and evaluation of an interactive, narrative-based, multimedia game to promote learning and communication about sexual violence and health topics. High school-aged participants created the game concept in a three-week workshop, after which assets were assembled and refined by a university-based game design lab. The outcome, Lucidity, was a multimedia game with a nonlinear narrative that led to two different outcomes based on player decisions. The narrative followed the life of one character, an African American woman named Zaria who remembers and grapples with a sexual assault from her past. The player discovers parts of the story by reading comics, watching videos, navigating interactive websites and playing short videogames. The final evaluation consisted of gameplay, a post-game focus group and follow-up interviews. Twenty-four young people participated in three focus group discussions (n = 9, n = 5, n = 10); 23 participated in the follow-up interviews. Salient themes identified in the focus group discussions included: overall approval of the game, the acquisition of new knowledge and minimal past exposure to conversations or education about sexual violence. At follow-up, almost all (n = 22) had initiated a conversation about sexual violence with a parent, peer and/or teacher. Lucidity succeeded in engaging young people and facilitating communication with adults and peers regarding sexual violence and other sexual health topics. Ultimately, a game-based intervention such as this represents a feasible approach for introducing issues of sexual violence, with potential for future implementation in educational settings.  相似文献
