Genetic and environmental influences on writing and their relations to language and reading

Identical and fraternal twins (N?=?540, age 8 to 18 years) were tested on three different measures of writing (Woodcock-Johnson III Tests of Achievement—Writing Samples and Writing Fluency; Handwriting Copy from the Group Diagnostic Reading and Aptitude Achievement Tests), three different language skills (phonological awareness, rapid naming, and vocabulary), and three different reading skills (word recognition, spelling, and reading comprehension). Substantial genetic influence was found on two of the writing measures, writing samples and handwriting copy, and all of the language and reading measures. Shared environment influences were generally not significant, except for Vocabulary. Non-shared environment estimates, including measurement error, were significant for all variables. Genetic influences among the writing measures were significantly correlated (highest between the speeded measures writing fluency and handwriting copy), but there were also significant independent genetic influences between copy and samples and between fluency and samples. Genetic influences on writing were significantly correlated with genetic influences on all of the language and reading skills, but significant independent genetic influences were also found for copy and samples, whose genetic correlations were significantly less than 1.0 with the reading and language skills. The genetic correlations varied significantly in strength depending on the overlap between the writing, language, and reading task demands. We discuss implications of our results for education, limitations of the study, and new directions for research on writing and its relations to language and reading.  相似文献   

“As ugly and painful as it was,it was effective:” Individuals' unique assessment of communication competence during aggressive conflict episodes     

Loreen N. Olson 《Communication Studies》2013,64(2):171-188

Communication competence plays a role in several problematic relational issues such as conflict management, interpersonal aggression, loneliness, and sexual coercion. This study examined the relationship between communication competence and aggression. Thirty‐one individuals (26 females, 5 males) experiencing aggression during conflict episodes with romantic partners were interviewed, generating 967 pages of transcribed data. The qualitative data analysis revealed that many of the participants assessed their use of aggression according to social customs, finding it inappropriate and ineffective. However, many noted their aggression was appropriate and effective given the circumstances of their relationship. These findings suggest a unique relational culture where aggression is perceived in ways that deviate from social norms. The theoretical and practical implications are discussed.  相似文献   

Comparison of Three Methods of Estimating Energy Expenditure: Caltrac,Heart Rate,and Video Analysis

Abstract

This study examined the accuracy of a new device (Caltrac) in estimating energy expenditure via acceleration measurements. Energy expenditure of 20 high school students during basketball class activity (average length = 37 min) was estimated using the Caltrac, heart rate recording, and video analysis. Heart rate recording and video analysis estimates of energy expenditure were determined from heart rate, caloric expenditure curves, and an activity rating scale, respectively. The following estimates of caloric expenditure (M ± SD) were found: heart rate recording = 196 ±73 > Caltrac = 163 ±49 > film analysis = 123 ± 30 kcal (p < .05). Laboratory simulations of the basketball activity revealed that the Caltrac energy expenditure was not significantly different from the actual energy expenditure (p > .05). The heart rate recording and video analysis estimates of energy expenditure were significantly (p < .05) higher and lower, respectively, than the actual energy expenditure. The Caltrac is a lightweight, low-cost device that provides a relatively accurate estimate of energy expenditure in free-ranging activities, such as basketball.  相似文献   

Musculoskeletal ultrasound training encourages self-directed learning and increases confidence for clinical and anatomical appreciation of first-year medical students     

Casey C. Brown  Shalynn D. Arrington  Jay F. Olson  Charles A. Finch Jr  Randall L. Nydam 《Anatomical sciences education》2022,15(3):508-521

Best-practice guidelines have incorporated ultrasound in diagnostic and procedural medicine. Due to this demand, the Arizona College of Osteopathic Medicine initiated a comprehensive integration of ultrasound into its first-year anatomy course attended by more than 280 students. Ultrasound workshops were developed to enhance student conceptualization of musculoskeletal (MSK) anatomy through visualizing clinically important anatomical relationships, a simulated lumbar puncture during the back unit, carpal tunnel and shoulder evaluations during the upper limb unit, and plantar fascia, calcaneal tendon, and tarsal tunnel evaluations during the lower limb unit. A 5-point Likert scale survey evaluated if ultrasound improved students' self-perceived anatomical and clinical comprehension of relevant anatomy, improved students' ability to orient to ultrasound imagery, and prompted further independent investigation of the anatomical area. Ultrasound examination questions were added to the anatomy examinations. Two-tailed one-sample t-tests for the back, upper limb, and lower limb units were found to be significant across all Likert survey categories (P < 0.001). Positive student responses to the Likert survey in conjunction with examination question average of 84.3% (±10.3) demonstrated that the ultrasound workshops are beneficial to student education. Ultrasound enhances medical students' clinical and anatomical comprehension and ability to orient to ultrasound imagery for MSK anatomy. This study supports early ultrasound education as a mechanism to encourage students' independent learning as evidenced by many undertaking voluntary investigation of clinical concerns associated with MSK anatomy. This study establishes the successful integration of MSK ultrasound into a large medical school program and its benefit to student clinical education.  相似文献   

Integration of programmable microfluidics and on-chip fluorescence detection for biosensing applications     

J. W. Parks  M. A. Olson  J. Kim  D. Ozcelik  H. Cai  R. Carrion  Jr.  J. L. Patterson  R. A. Mathies  A. R. Hawkins  H. Schmidt 《Biomicrofluidics》2014,8(5)

We describe the integration of an actively controlled programmable microfluidic sample processor with on-chip optical fluorescence detection to create a single, hybrid sensor system. An array of lifting gate microvalves (automaton) is fabricated with soft lithography, which is reconfigurably joined to a liquid-core, anti-resonant reflecting optical waveguide (ARROW) silicon chip fabricated with conventional microfabrication. In the automaton, various sample handling steps such as mixing, transporting, splitting, isolating, and storing are achieved rapidly and precisely to detect viral nucleic acid targets, while the optofluidic chip provides single particle detection sensitivity using integrated optics. Specifically, an assay for detection of viral nucleic acid targets is implemented. Labeled target nucleic acids are first captured and isolated on magnetic microbeads in the automaton, followed by optical detection of single beads on the ARROW chip. The combination of automated microfluidic sample preparation and highly sensitive optical detection opens possibilities for portable instruments for point-of-use analysis of minute, low concentration biological samples.  相似文献

The Use of BISAC in Libraries as New Cases of Reader-Interest Classifications     

Daniel Martínez-Ávila  Rosa San Segundo  Hope A. Olson 《Cataloging & classification quarterly》2014,52(2):137-155

In the recent years, several libraries in the United States have been experimenting with Book Industry Standards and Communications (BISAC), the classification system of the book industry, as an alternative to the Dewey Decimal Classification. Although rarely discussed, these cases of implementation of BISAC arguably resemble other past cases of replacement of traditional classifications that received the name of reader-interest classifications. In this article, a comparison of the BISAC cases to the previous cases of reader-interest classifications is taken in order to determine if the current application of BISAC to libraries is susceptible to the same problems, dangers, and ends as occurred in the past.  相似文献

Item Analysis,Measurement, and Instruction     

Leroy A. Olson 《College Teaching》2013,61(3):163-164

This research project examines students' reactions to in-class discussion as an instructional technique by investigating the effect of participation practices on communication-based skill development. The findings provide evidence that active preparation and participation in class discussion can be linked to students' reports of improved oral and written communication skills. Conclusions suggest that discussion can be a useful addition to cross-curricular programs (such as writing and speaking across the curriculum) and standalone courses (such as public speaking). This technique can be used in combination with other strategies.  相似文献
