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

Evidence from the research literature suggests that a variety of cognitive factors is responsible for chemistry achievement. This investigation examined the role of four cognitive factors, namely, formal reasoning ability, prior knowledge, field dependence/ independence, and memory capacity on achievement in chemistry as measured by tests of laboratory application, chemical calculations and content knowledge. The sample comprised grade 11 students from eleven high schools who were following the same chemistry syllabus. The results indicated that prior knowledge and formal reasoning ability were each statistically significantly related to variation in chemistry achievement. Field dependence/independence and memory capacity played no significant role in chemistry achievement. 相似文献

Chemical composition of gall stones is essential for aetiopathogensis of gallstone disease. We have reported quantitative
chemical analysis of total cholesterol bilirubin, calcium, iron and inorganic phosphate in 120 gallstones from haryana. To
extend this chemical analysis of gall stones by studying more cases and by analyzing more chemical constituents. A quantitative
chemical analysis of total cholesterol, total bilirubin, fatty acids, triglycerides, phospholipids, bile acids, soluble proteins,
sodium potassium, magnesium, copper, oxalate and chlorides of biliary calculi (52 cholesterol, 76 mixed and 72 pigment) retrieved
from surgical operation of 200 patients from Haryana state was carried out. Total cholesterol as the major component and total
bilirubin, phospholipids, triglycerides, bile acids, fatty acids (esterified), soluble protein, calcium, magnesium, iron,
copper, sodium, potassium, inorganic phosphate, oxalate and chloride as minor components were found in all types of calculi.
The cholesterol stones had higher content of total cholesterol, phospholipids, fatty acids (esterified), inorganic phosphate
and copper compared to mixed and pigment stones. The mixed stones had higher content of iron and triglycerides than to cholesterol
and pigment stones. The pigment stones were richer in total bilirubin, bile acids, calcium, oxalate, magnesium, sodium, potassium,
chloride and soluble protein compared to cholesterol and mixed stones. Although total cholesterol was a major component of
cholesterol, mixed and pigment gall stone in Haryana, the content of most of the other lipids, cations and anions was different
in different gall stones indicating their different mechanism of formation. 相似文献

This article describes the design and advocacy of the Bachelor of Fine Arts in Jazz and Contemplative Studies curriculum at The University of Michigan School of Music. The curriculum combines meditation practice and related studies with jazz and overall musical training and is part of a small but growing movement in academia that seeks to integrate contemplative disciplines within the educational process. The article considers issues such as the structure of the curriculum, the reconciliation of contemplative studies and conventional notions of academic rigor, the avoidance of possible conflicts between church and state, and other challenges encountered in gaining support for this plan, after weeks of intensive debate, from a 2/3 majority of the faculty. 相似文献

Student performance has become an increasingly important topic in higher education as it relates to retention and graduation rates and as university administrators place emphasis on performance as the basis for budgeting. The purpose of this research was to determine to what extent students' ability, achievement striving, and situational optimism influence performance outcomes and to investigate the interactive effects of ability and achievement striving as well as ability and situational optimism on student performance outcomes. Study results and implications for institute of higher education and classroom instructions are also discussed. 相似文献

The popular method of organising youth sport participants into age divisions, based solely on their birthdate, can result in an imbalance of the distribution of players. This is known as relative age effect (RAE), which inadvertently creates bias and is associated with deleterious short and long-term consequences. The overall purpose of this study was to examine how the potential for RAE is mitigated when simultaneously accounting for additional player criterion, supplementary to age. A mid-Atlantic American youth football registration database was acquired, including chronological (age), anthropometric (weight), and competency (skill) factors. Player (n = 1,265) data were classified into quartiles and multiple chi-square goodness of fit tests were conducted using proportions of live births as expected theoretical distribution values. When data were categorised by a single developmental criterion (e.g. age), results indicated significant departures (p ≤ 0.002) from expected proportions. However, when categorised using multiple criteria (i.e. age, weight, and skill), equitable birthdate distributions were observed. Findings from this study indicate using only one developmental criterion for organising players is associated with RAE, whereas approaches accounting for multiple variables are not associated with RAE. This study provides youth football programs with early evidence for considering alternative methods of organising players. 相似文献
