This review presents a conceptual framework and supporting evidence that links impaired motor control after sport-related concussion (SRC) to increased risk for musculoskeletal injury. Multiple studies have found that athletes who are post-SRC have higher risk for musculoskeletal injury compared to their counterparts. A small body of research suggests that impairments in motor control are associated with musculoskeletal injury risk. Motor control involves the perception and processing of sensory information and subsequent coordination of motor output within the central nervous system to perform a motor task. Motor control is inclusive of motor planning and motor learning. If sensory information is not accurately perceived or there is interference with sensory information processing and cognition, motor function will be altered, and an athlete may become vulnerable to injury during sport participation. Athletes with SRC show neuroanatomic and neurophysiological changes relevant to motor control even after meeting return to sport criteria, including a normal neurological examination, resolution of symptoms, and return to baseline function on traditional concussion testing. In conjunction, altered motor function is demonstrated after SRC in muscle activation and force production, movement patterns, balance/postural stability, and motor task performance, especially performance of a motor task paired with a cognitive task (i.e., dual-task condition). The clinical implications of this conceptual framework include a need to intentionally address motor control impairments after SRC to mitigate musculoskeletal injury risk and to monitor motor control as the athlete progresses through the return to sport continuum.  相似文献   

Heterogeneity in the Effects of College Course Placement     

Daugherty  Lindsay  Gerber  Russell  Martorell  Francisco  Miller  Trey  Weisburst  Emily 《Research in higher education》2021,62(7):1086-1111

Traditionally colleges have relied on standalone non-credit-bearing developmental education (DE) to support students academically and ensure readiness for college-level courses. As emerging evidence has raised concerns about the effectiveness of DE courses, colleges and states have been experimenting with approaches that place students into credit-bearing coursework more quickly. To better understand which types of students might be most likely to benefit from being placed into college-level math coursework, this study examines heterogeneity in the causal effects of placement into college-level courses using a regression discontinuity design and administrative data from the state of Texas. We focus on student characteristics that are related to academic preparation or might signal a student’s likelihood of success or need for additional support and might therefore be factors considered for placement into college-level courses under “holistic advising” or “multiple measures” initiatives. We find heterogeneity in outcomes for many of the measures we examined. Students who declared an academic major designation, had bachelor’s degree aspirations, tested below college readiness on multiple subjects, were designated as Limited English Proficiency (LEP), and/or were economically disadvantaged status were more likely to benefit from placement into college-level math. Part-time enrollment or being over the age of 21 were associated with reduced benefits from placement into college-level math. We do not find any heterogeneity in outcomes for our high school achievement measure, three or more years of math taken in high school.

Science and scientists in Victorian and Edwardian literary novels: insights into the emergence of a new profession     

Russell N 《Public understanding of science (Bristol, England)》2007,16(2):205-222

Literary fiction has seldom been seriously considered as a mode of science communication. Here, I review novels from the 19th century canon of English literature in which characters either have, or aspire to have, substantive professional scientific roles to see what insights they provide into the practice of science in the Victorian and Edwardian eras. They reflect the historical transition of science from an intellectual hobby to a paid occupation, but also reveal that while a career in science became possible for a wider range of people, it seldom allowed these new entrants to undertake fundamental scientific research.  相似文献   

Exploring factors that influence adoption of e‐learning within higher education          下载免费PDF全文

Emma King  Russell Boyatt 《British journal of educational technology : journal of the Council for Educational Technology》2015,46(6):1272-1280

E‐learning is increasingly adopted in the workplace for supporting professional development and continuing education; however, in higher education, the use of e‐learning is predominantly used as a tool support teaching. As a relatively new priority for universities, this paper explores what influences its adoption. Challenges identified in the literature include organisational features of universities like faculty autonomy and dispersed academic perspectives. This study, carried out at the University of Warwick, adopted a phenomenological approach and explored participants' perceptions through a series of faculty‐based focus groups and individual interviews. Factors identified as influential to adoption of e‐learning included the institutional infrastructure, staff attitudes and skills, and perceived student expectations. Participants suggested the importance of an institutional strategy targeted at providing sufficient resources and guidance for effective implementation. This strategy needs to be supported by a varied programme of staff development and opportunities for sharing practice among colleagues. In further developing understanding in this area, it would be beneficial to replicate the study with other stakeholder groups (including the leadership team and students) to develop an institutional strategy responsive at all levels of implementation. It would also be valuable to investigate the extent to which these findings are replicated within other workplaces looking to adopt innovation.  相似文献   

Students’ Perspectives on LGBTQ-Inclusive Curriculum     

Shannon D. Snapp  Hilary Burdge  Adela C. Licona  Raymond L. Moody  Stephen T. Russell 《Equity & Excellence in Education》2015,48(2):249-265

Implementing curriculum that is inclusive of lesbian, gay, bisexual, transgender, queer, and questioning (LGBTQ) people has the potential to create an equitable learning environment. In order to learn more about students’ experiences of LGBTQ-inclusive curriculum, 26 high school students with diverse racial/ethnic, sexual, and gender identities were recruited from the Gay Straight Alliance (GSA) Network in California. Students participated in focus groups conducted by telephone by GSA staff, sharing their experiences of LGBTQ-inclusive curriculum in school. Qualitative coding methods, including grounded theory, were used to identify themes and interpret students’ responses. Data revealed that LGBTQ-inclusive curriculum was most often taught in social sciences and humanities courses as stand-alone lessons. LGBTQ-inclusive curriculum rarely met standards of social justice education, though opportunities for critical conversations about systemic oppression regularly emerged. For instance, teachers often failed to intervene in LGBTQ bullying and missed teachable moments conducive to inclusive curriculum. Some students learned positive LGBTQ lessons and highlighted the ways such curriculum reflected their identities and created a supportive school climate. Implications for equitable education are discussed.  相似文献   

Improved Appreciation of Mathematics Through an IBL Liberal Arts Mathematics Course     

Russell D. Blyth 《PRIMUS》2015,25(3):265-278

Abstract

The author has taught an inquiry-based liberal arts mathematics class using the text “The Heart of Mathematics: An Invitation to Effective Thinking” by Edward B. Burger and Michael Starbird a total of 20 times since Spring 2001. The students in this class have almost all been in non-technical majors and many started the semester with negative or ambivalent attitudes toward mathematics based on their prior experiences. The author has gathered responses from students in this class that illustrate significant changes in their attitudes towards mathematics during the course. In particular, the responses gathered at the end of the semester are often eloquent about understanding the great ideas of mathematics that students confronted in this course and about seeing many more and varied connections between mathematics and the “real world” than they had previously realized existed.  相似文献   

When worlds collide: identity,culture and the lived experiences of research when ‘teaching-led’     

John G. Sharp  Brian Hemmings  Russell Kay  Carol Callinan 《Journal of Further & Higher Education》2015,39(5):612-644

This article presents detailed findings from the qualitative or interpretive phase of a mixed-methods case study focusing on the professional identities and lived experiences of research among six lecturers working in different capacities across the field of education in a ‘teaching-led’ higher education institution. Building upon the quantitative phase published earlier in this journal, factors both facilitating (e.g. research infrastructure, support for doctoral study) and constraining (e.g. time, space, workload, critical mass, ‘practitioner bond professionalism’, ‘organisational socialisation’, networks, roles and responsibilities, power relationships) research activity are identified. These are considered in the context of an institution often recruiting staff with ‘non-traditional’ backgrounds from within ‘the professions’ (e.g. from schools and colleges without doctorates) looking to become more ‘research-informed’ and establish a more vibrant and sustainable research culture. Recommendations for further development focus on ‘identity transitions’ and ‘cultural transformation’, emphasising the importance of research leadership and its distribution throughout the organisation. With current trends towards the apparent intensification and prioritisation of research activity over teaching, findings are considered particularly important for institutions of a similar nature to the one described here, for education departments in larger institutions also on similar journeys, and in light of an anticipated increase in demand for research activity arising from the expansion of higher education provision in further education and the private sector, where recruitment from within ‘the professions’ to teach across ‘vocational’ programmes is common.  相似文献   

Preparing the Next Generation of Educational Measurement Specialists: A Call for Programs With an Integrated Scope and Sequence     

Mike Russell  Larry Ludlow  Laura O'Dwyer 《Educational Measurement》2019,38(4):78-86

The field of educational measurement has evolved considerably since the first doctoral programs were established. In response, programs have typically tacked on courses that address newly developed theories, methods, tools, and techniques. As our review of current programs evidences, this approach produces artificial distinctions among topics and techniques that are in fact a tightly coupled whole. This position paper advocates a redesign of the scope and sequence for doctoral programs focused on the preparation of the next generations of educational measurement specialists; a redesign that reflects the full life‐cycle of instrument development and use.  相似文献   

Response Time Adjustment in the Stop Signal Task: Development in Children and Adolescents

Adjusting speed to maintain fast and accurate performance is critical to goal-directed behavior. This study examined development of response time adjustments in the stop signal task in 13,709 individuals aged 6–17 years (49.0% Caucasian) across four trial types: correct and incorrect go, successful (stop-inhibit), and failed (stop-respond) trials. People sped more after correct than incorrect go responses and slowed more after failed than successful stop trials. Greater slowing after stop-respond but less slowing after stop-inhibit trials was associated with better response inhibition. Response time adjustments were evident in children as young as age 6, developed throughout childhood, and plateaued by age 10. Results were consistent with the predictions of the error detection and shifting goal priority hypotheses for adjustments.  相似文献
