BackgroundDeveloping appropriate concussion prevention and management paradigms in middle school (MS) settings requires understanding parents’ general levels of concussion-related knowledge and attitudes. This study examined factors associated with concussion-symptom knowledge and care-seeking attitudes among parents of MS children (aged 10–15 years).MethodsA panel of 1224 randomly selected U.S. residents, aged ≥ 18 years and identifying as parents of MS children, completed an online questionnaire capturing parental and child characteristics. The parents’ concussion-symptom knowledge was measured using 25 questions, with possible answers being “yes”, “maybe”, and “no”. Correct answers earned 2 points, “maybe” answers earned 1 point, and incorrect answers earned 0 point (range: 0–50; higher scores = better knowledge). Concussion care-seeking attitudes were also collected using five 7-point scale items (range: 5–35; higher scores = more positive attitudes). Multivariable ordinal logistic regression models identified predictors of higher scores. Models met proportional odds assumptions. Adjusted odds ratios (aORs) with 95% confidence intervals (95%CIs) (excluding 1.00) were deemed statistically significant.ResultsMedian scores were 39 (interquartile range: 32–44) for symptom knowledge and 32 (interquartile range: 28–35) for care-seeking attitude. In multivariable models, odds of better symptom knowledge were higher in women vs. men (aOR = 2.28; 95%CI: 1.71–3.05), white/non-Hispanics vs. other racial or ethnic groups (aOR = 1.88; 95%CI: 1.42–2.49), higher parental age (10-year-increase aOR = 1.47; 95%CI: 1.26–1.71), and greater competitiveness (10%-scale-increase aOR = 1.24; 95%CI: 1.13–1.36). Odds of more positive care-seeking attitudes were higher in white/non-Hispanics vs. other racial or ethnic groups (aOR = 1.45; 95%CI: 1.06–1.99) and in older parental age (10-year-increase aOR = 1.24; 95%CI: 1.05–1.47).ConclusionCharacteristics of middle school children''s parents (e.g., sex, race or ethnicity, age) are associated with their concussion-symptom knowledge and care-seeking attitudes. Parents’ variations in concussion knowledge and attitudes warrant tailored concussion education and prevention.  相似文献   

Linking Mind,Brain, and Education to Clinical Practice: A Proposal for Transdisciplinary Collaboration     

Katie Ronstadt  Paul B. Yellin 《Mind, Brain, and Education》2010,4(3):95-101

It has been suggested that the field of Mind, Brain, and Education (MBE) requires a stable infrastructure for translating research into practice. Hinton and Fischer (2008) point to the academic medical center as a model for similar translational work and suggest a similar approach for linking scientists to research schools. We propose expanding their model to include a formal role for clinicians. Including clinicians who work with children with learning problems brings an important perspective to the translational work. For example, the integration of the concept of “differential diagnosis,” a core precept in clinical medicine, would bring needed diagnostic specificity to the field of MBE. We describe a virtual infrastructure for collaboration, or “collaboratory,” consisting of research scientists, educators, and clinicians, linked to an academic institution. We anticipate that MBE graduates can play a critical role in the collaboratory model. With additional training, they can become “neuroeducators” capable of moving comfortably among the disciplines, building linkages, fostering communication, and facilitating collaboration.  相似文献   

Effects of coffee and caffeine anhydrous on strength and sprint performance     

Eric T. Trexler  Erica J. Roelofs  Katie R. Hirsch  Meredith G. Mock 《European Journal of Sport Science》2016,16(6):702-710

Caffeine and coffee are widely used among active individuals to enhance performance. The purpose of the current study was to compare the effects of acute coffee (COF) and caffeine anhydrous (CAF) intake on strength and sprint performance. Fifty-four resistance-trained males completed strength testing, consisting of one-rep max (1RM) and repetitions to fatigue (RTF) at 80% of 1RM for leg press (LP) and bench press (BP). Participants then completed five, 10-second cycle ergometer sprints separated by one minute of rest. Peak power (PP) and total work (TW) were recorded for each sprint. At least 48 hours later, participants returned and ingested a beverage containing CAF (300?mg flat dose; yielding 3–5?mg/kg bodyweight), COF (8.9?g; 303?mg caffeine), or placebo (PLA; 3.8?g non-caloric flavouring) 30 minutes before testing. LP 1RM was improved more by COF than CAF (p?=?.04), but not PLA (p?=?.99). Significant interactions were not observed for BP 1RM, BP RTF, or LP RTF (p?>?.05). There were no sprint?×?treatment interactions for PP or TW (p?>?.05). 95% confidence intervals revealed a significant improvement in sprint 1 TW for CAF, but not COF or PLA. For PLA, significant reductions were observed in sprint 4 PP, sprint 2 TW, sprint 4 TW, and average TW; significant reductions were not observed with CAF or COF. Neither COF nor CAF improved strength outcomes more than PLA, while both groups attenuated sprint power reductions to a similar degree. Coffee and caffeine anhydrous may be considered suitable pre-exercise caffeine sources for high-intensity exercise.  相似文献   

Conditioning with taste as the CS in conditioned flavor preference learning     

Elizabeth D. Capaldi  Martin J. Hunter  Sandra A. Lyn 《Learning & behavior》1997,25(4):427-436

There appear to be unconditioned affective reactions to the four basic tastes: liking for sweet and salt and disliking for sour and bitter. We attempted to modify these reactions by pairing the tastes with calories and with sweeter tastes. Differing sucrose concentrations were ineffective in reversing the preference for salt over citric acid or for saccharin over quinine. We could, however, reverse the preference for salt over citric acid, producing an actual preference for sour over salt, by using sucrose and saccharin as the reinforcers. The initial reactions to tastes could also be modified by reducing the initial difference in affect produced by the tastes through mixing both tastes with sucrose.  相似文献   

Sharing teacher knowledge at scale: teacher inquiry,learning design and the representation of teachers’ practice     

Martin Oliver  Katerina Avramides  Wilma Clark  Jade Hunter  Rose Luckin  Cecilie Hansen 《Teacher Development》2018,22(4):587-606

Sharing teachers’ professional knowledge remains challenging. Teachers’ development often remains ad hoc or local, and attempts to scale this up have proved problematic. To address this, research in areas such as ‘learning design’ has explored the use of formal representations of practice. This proposes that educational practice can be improved by documenting, sharing and building on what teachers already do. Whilst this has led to some successes, it has not resulted in the widespread transformation of practice. This paper reviews the literature about sharing teacher knowledge. The challenges of scaling up development are then considered in relation to two theories that help explain the challenges: Communities of Practice and Sociomateriality. This analysis is illustrated through case studies in Norway and the UK. These show that teachers already create and share artefacts that represent their pedagogic knowledge. However, they found formal representations, such as learning designs, difficult to work with. The paper concludes that scaling up teacher development using abstract formalisms is unlikely to succeed. Instead, teachers value stories and the materials they already create in their day-to-day practice. It is this intermediate level of representation, between direct experience and formal abstraction, that offers the most promise for sharing practice.  相似文献   

Classroom environments that foster a disposition for critical thinking     

Samuel R. Mathews  Katie Lowe 《Learning Environments Research》2011,14(1):59-73

In this article, we examine the disposition for critical thinking (CT) from three perspectives and analyse the underlying constructs of the disposition for CT, such as one’s ability, sensitivity and inclination to engage in critical, mindful thought. Environmental factors that enhance or inhibit the development of a generalisable disposition for critical thought are discussed. Finally, we present a set of empirically-verified classroom practices that can help to foster a disposition for CT.  相似文献   

Determinants of placement for sexually abused children     

W M Hunter  M L Coulter  D K Runyan  M D Everson 《Child abuse & neglect》1990,14(3):407-417

While conducting a prospective study of 100 sexually abused children, we found a much higher rate of out-of-home placement than has been previously described for child maltreatment. This study was designed to determine which factors were most influential in predicting the placement experiences of this cohort. The children, ages 6-17 years, were recently substantiated victims of intrafamilial sexual abuse whose parents or guardians permitted study involvement. We examined child and family demographics, abuse characteristics, and family response as possible determinants of immediate and later placement. At the initial assessment, within a few weeks of the disclosure, 50% of the children had already been removed. A follow-up assessment of 83 children two years later revealed that 73% had been removed from the abusing home. In a multivariate regression model, only maternal support of the child emerged as a significant predictor of immediate placement and placement over time. The offender's status as a resident in the child's home was an important predictor of immediate placement but was not significant as a predictor of all placements at any time. As maternal support is an important predictor of the need for placement, workers are encouraged to seek ways of enhancing maternal support as a means of reducing placement.  相似文献
