The purpose of this study was to investigate the nature of inter-joint coordination at different levels of skilled performance to: (1) distinguish learners who were successful versus unsuccessful in terms of their task performance; (2) investigate the pathways of change during the learning of a new coordination pattern and (3) examine how the learner’s coordination patterns relate to those of experts in the longswing gymnastics skill. Continuous relative phase of hip and shoulder joint motions was examined for longswings performed by two groups of novices, successful (n = 4) and unsuccessful (n = 4) over five practice sessions, and two expert gymnasts. Principal component analysis showed that during longswing positions where least continuous relative phase variability occurred for expert gymnasts, high variability distinguished the successful from the unsuccessful novice group. Continuous relative phase profiles of successful novices became more out-of-phase over practice and less similar to the closely in-phase coupling of the expert gymnasts. Collectively, the findings support the proposition that at the level in inter-joint coordination a technique emerges that facilitates successful performance but is not more like an expert’s movement coordination. This finding questions the appropriateness of inferring development towards a “gold champion” movement coordination.  相似文献   

Self-regulation of learning and preference for written versus audio-recorded feedback by distance education students     

Genevieve Marie Johnson  Audrey Cooke 《Distance Education》2016,37(1):107-120

Teacher feedback is critically related to student learning. This study sought to determine the relationships between distance education (DE) student level of self-regulated learning (SRL) and their preference for audio-recorded vs. written feedback from tutors. DE students (n = 102) enrolled in a first-year university course completed an online questionnaire that assessed eight dimensions of SRL as well as a personal evaluation of written vs. audio-recorded tutor feedback that was provided during the academic study period. In general, the participating DE students expressed preference for written over audio-recorded feedback. However, complex patterns of relationships emerged between dimensions of SRL and evaluation of written vs. audio-recorded feedback. For example, DE students who were most likely to listen to audio-recorded feedback appreciated peer interaction and personal challenges more than students who preferred written feedback. In DE learning environments, a variety of feedback formats may best meet the needs of all students, although exposure to various technologies may facilitate SRL.  相似文献   

Factors That Impact College Students’ Perceptions of Sexual Pleasure and Satisfaction     

Susan Milstein  Taylor Elizabeth Hilliard  Scott Hall  David Knox  Genevieve Hunter 《American journal of sexuality education》2020,15(1):99-110

Abstract

It is important to understand how people experience pleasure and sexual satisfaction with a partner, as these phenomena can impact how they view their relationships, themselves, as well as the role of sexual activities within relationships. Three hundred and four undergraduates at East Carolina University and California State University Chico who reported having at least one sexual experience with a partner completed a 45 item survey assessing social correlates of sexual pleasure and sexual satisfaction. Analysis revealed that those in a committed relationship reported the highest sexual pleasure (on average), followed by those in an emotionally-involved relationship, followed by those in a hookup. A parallel analysis for sexual satisfaction revealed the same associations. Regarding the length of relationship, being in a relationship for at least six weeks appeared to matter for pleasure and satisfaction, but being in a relationship longer than six months did not indicate greater advantages than those in a relationship between six weeks and six months. Limitations of the research are identified.  相似文献   

The Reported Effects of a Systematic Professional Learning Program on the Knowledge,Skills, and Concerns of Australian Early Childhood Educators who Support Young Children Displaying or at Risk of Challenging Behaviours     

Michael Arthur-Kelly  Genevieve Farrell  Tania De Bortoli  Gordon Lyons  Frank Hinchey  Fuk Chuen Ho 《International Journal of Disability, Development & Education》2017,64(2):131-149

High-quality early childhood education is a vital experience for young children with and without disabilities. Social and communication experiences in the context of play represent a core curriculum that sets a foundation for later learning and participation. Using a new self-report instrument, this article describes data collected in a large-scale professional learning project in NSW, Australia, that aimed to support early childhood teachers, paraprofessionals and other personnel who directly work with young children, including individuals who present or are at risk of challenging behaviours. Using a case application model of remote and direct coaching support and intervention centred on the input of expert practitioners, the reports of participants were collected before and after a series of three sequential workshops with embedded action research processes for participants. The program was designed to increase social and communicative exchanges and reduce the likelihood of challenging behaviours, by providing a systematic and practical framework for the introduction of functional behavioural assessment and positive support planning. Respondents indicated significant improvements in knowledge and skills after the program, along with decreased concerns in some areas. The paper concludes by discussing potential areas for an expanded research agenda into the professional learning needs of personnel in this field and more broadly within early childhood support systems and services.  相似文献

Multidimensional joint coupling: a case study visualisation approach to movement coordination and variability     

Gareth Irwin  David G. Kerwin  Genevieve Williams  Richard E. A. Van Emmerik  Karl M. Newell  Joseph Hamill 《Sports biomechanics / International Society of Biomechanics in Sports》2020,19(3):322-332

Abstract

A case study visualisation approach to examining the coordination and variability of multiple interacting segments is presented using a whole-body gymnastic skill as the task example. One elite male gymnast performed 10 trials of 10 longswings whilst three-dimensional locations of joint centres were tracked using a motion analysis system. Segment angles were used to define coupling between the arms and trunk, trunk and thighs and thighs and shanks. Rectified continuous relative phase profiles for each interacting couple for 80 longswings were produced. Graphical representations of coordination couplings are presented that include the traditional single coupling, followed by the relational dynamics of two couplings and finally three couplings simultaneously plotted. This method highlights the power of visualisation of movement dynamics and identifies properties of the global interacting segmental couplings that a more formal analysis may not reveal. Visualisation precedes and informs the appropriate qualitative and quantitative analysis of the dynamics.  相似文献   

“We (Tong) Chinese”: Contemporary identity positioning through health management among Cantonese Chinese Americans     

Genevieve Leung  Evelyn Y. Ho  Han-Lin Chi  Siyuan Huang  Isabelle K. Ting  Donald Chan 《Journal of International and Intercultural Communication》2018,11(4):271-285

This paper explores discursive ways Chinese American older adults with type 2 diabetes mellitus (T2DM) take ownership of their health management. Fifteen patient stakeholders with T2DM took part in four focus group interviews. We used qualitiative discourse analysis to examine how participants used the phrase, “We (Tong) Chinese,” and variants, to index models of Chinese-living-in-the-U.S. personhoods, to incorporate “Chinese” and “western” ways of doing health management, to be Chinese American, and to interact with medical practitioners. We show how terms like “Tong” distinguish transnational boundaries and position participants in claiming “Chinese-in-America-ness” in relevant ways. Findings have implications for healthcare providers, health education, and intercultural communication.  相似文献   

Gender influence on the adaptation of atrial performance to training     

Laura Sanchis  Maria Sanz-de La Garza  Bart Bijnens  Genevieve Giraldeau  Gonzalo Grazioli  Josefa Marin 《European Journal of Sport Science》2017,17(6):720-726

Background: High-intensity training has been associated with atrial remodelling and arrhythmias in men. Our purpose was to analyse atrial performance in female endurance athletes, compared to male athletes and controls. Methods: This was a cross-sectional study. We included four groups: female athletes, females controls, male athletes and male controls. Left (LA) and right atrial (RA) volumes and function were assessed using 2D and speckle-tracking echocardiography to determine peak atrial strain-rate at atrial (SRa) and ventricular contraction (SRs), as surrogates of atrial contractile and reservoir function, respectively. ANOVA and Bonferroni’s statistical tests were used to compare variables among groups. Results: We included 82 subjects, 39 women (19 endurance athletes, 20 controls) and 43 men (22 endurance athletes, 21 controls). Mean age was similar between groups (36.6?±?5.6 years). Athletes had larger bi-atrial volumes, compared to controls (women, LA 27.1 vs. 15.8?ml/m², p?<?0.001; RA 22.31 vs. 14.2?ml/m², p?=?0.009; men, LA: 25.0 vs. 18.5?ml/m², p?=?0.003; RA 30.8 vs. 21.9?ml/m², p?<?0.001) and lower strain-rate (women, LASRa ?1.60 vs. ?2.18?s^?1, p?<?0.001; RASRa ?1.89 vs. ?2.38?s^?1, p?=?0.009; men, LASRa ?1.21 vs. ?1.44?s^?1, p?=?1; RASRa ?1.44 vs. ?1.60?s^?1, p?=?1). However, RA indexed size was lower and bi-atrial deformation greater in female athletes, compared to male athletes. Conclusions: The atria of both male and female athletes shows specific remodelling, compared to sedentary subjects, with larger size and less deformation at rest, particularly for the RA. Despite a similar extent of remodelling, the pattern in women had greater bi-atrial myocardial deformation and smaller RA size.  相似文献   

Expanding assessment methods and moments in history     

Jennifer Frost  Genevieve de Pont  Ian Brailsford 《Assessment & Evaluation in Higher Education》2012,37(3):293-304

History courses at The University of Auckland are typically assessed at two or three moments during a semester. The methods used normally employ two essays and a written examination answering questions set by the lecturer. This study describes an assessment innovation in 2008 that expanded both the frequency and variety of activities completed by 182 undergraduates taking a course on the history of African‐American freedom struggles. All week‐by‐week tutorial assignments were collected for textual analysis to see if students were moving beyond the recollection and regurgitation of facts (surface learning) and instead were dealing with the deeper historical issues. The quality of student work coupled with our own classroom observations indicate that innovative assessment methods at regular moments during the semester made a positive difference to the student learning experience.  相似文献   

Thriving at the Intersection: Integrating Social Determinants of Health and Sexual Health Education to Achieve Positive Outcomes for Youth     

Genevieve Martínez-García  Lisette Torres  Carolyn Camacho  Hope Gleicher  Valerie Sedivy 《American journal of sexuality education》2018,13(3):337-358

Abstract

Social determinants of health are the key to understanding and addressing persistent disparities in adolescent pregnancy in the United States. However, there is little guidance on what concrete steps organizations can take to work at the intersection of social determinants of health (SDoH) and sexual and reproductive health (SH). Two community-based organizations completed a case study using a structured interview guide to illustrate their transition working at this intersection. The Alexandria Campaign on Adolescent Pregnancy and Identity, Inc. arrived at the intersection of SDoH and SH from opposite ends of the road. Despite clear differences in their trajectory, their experiences share four key elements that marked their success in expanding their core work: (a) both organizations enjoyed ample community and political support, (b) they used data to drive strategic decisions, (c) they used funding opportunities to move toward the intersection of sexual health and social determinants, and (d) they leveraged existing programs to sustain their efforts. Organizations working at the intersection must continuously leverage community, political, and financial capital to pursue partners, expand services, and change policies that sustain a holistic approach to youth health and well-being.  相似文献
