Mind what mother says: narrative input and theory of mind in typical children and those on the autism spectrum   总被引：5，自引：0，他引：5  

Slaughter V  Peterson CC  Mackintosh E 《Child development》2007,78(3):839-858

In 2 studies mothers read wordless storybooks to their preschool-aged children; narratives were analyzed for mental state language. Children's theory-of-mind understanding (ToM) was concurrently assessed. In Study 1, children's (N=30; M age 3 years 9 months) ToM task performance was significantly correlated with mothers' explanatory, causal, and contrastive talk about cognition, but not with mothers' simple mentions of cognition. In Study 2, the same pattern was found in an older sample of typically developing children (N=24; M age 4 years 7 months), whereas for children on the autism spectrum (N=24; M age 6 years 7.5 months), ToM task performance was uniquely correlated with mothers' explanatory, causal, and contrastive talk about emotions.  相似文献   

Secondary mathematics cooperating teachers’ perceptions of the purpose of student teaching     

Keith R. Leatham  Blake E. Peterson 《Journal of Mathematics Teacher Education》2010,13(2):99-119

This article reports on the results of a survey of 45 secondary mathematics cooperating teachers’ perceptions of the primary purposes of student teaching and their roles in accomplishing those purposes. The most common purposes were interacting with an experienced, practising teacher, having a real classroom experience, and experiencing and learning about classroom management. The most common roles were providing the space for experience, modeling, facilitating reflection, and sharing knowledge. The findings provided insights into the cooperating teachers’ perceptions about both what should be learned through student teaching and how it should be learned. These findings paint a picture of cooperating teachers who do not see themselves as teacher educators—teachers of student teachers. Implications for mathematics teacher educators are discussed.  相似文献   

A review of biochemical and ultrasound markers in the detection of down syndrome     

Peterson CC 《The Journal of perinatal education》2006,15(1):19-25

Childbirth educators need to understand existing prenatal care opportunities and current information for expectant women. This article reviews several testing options that are available during the second trimester of pregnancy to detect the risk of Down syndrome. Educators can help expectant women develop their own specific plan of care according to their special situations and needs. Pregnancy outcomes can be improved when women are informed and educated about the testing available to them.  相似文献   

Pharmacists’ online information literacy: an assessment of their use of Internet‐based medicines information     

Geraldine Peterson‐Clark  Parisa Aslani  Kylie Anne Williams 《Health information and libraries journal》2010,27(3):208-216

Introduction: Pharmacists need effective skills in accessing and using Internet‐based medicines information (IBMI) for themselves and their consumers. However, there is limited information regarding how pharmacists use the Internet. Objectives: To develop and use a research instrument to measure pharmacists’ Internet knowledge, search skills, evaluation of and opinions about using IBMI. Methods: A structured questionnaire examining general Internet knowledge, ability to search for and select pertinent IBMI, evaluation of IBMI, opinions about using IBMI and current Internet use was developed. Exploratory factor analysis was performed to analyse IBMI evaluation. Results: 208 pharmacists responded (response rate 20.6%). There was a large variation in pharmacists’ scores. Mean scores were low for General Internet Knowledge (mean 7.91 ± 3.62; scale 0–16), Search and Selection of IBMI (4.98 ± 2.91; 0–10) and Opinions on IBMI (44.51 ± 9.61; 0–80). Four factors [Professionalism of website (4 items; factor loading 0.62–0.87; Cronbach’s α 0.84), Disclosure (5; 0.37–0.79; 0.73), Appropriateness of content (5; 0.32–0.50; 0.65), Standard of information (6; 0.31–0.48; 0.58)] were extracted from the evaluation scale, explaining 36.89% of the total variance. Conclusions: A tool was developed to evaluate pharmacists’ skills and opinions in using IBMI. A wide range of skills and opinions highlighted the need for training in online information literacy.  相似文献

Cycling on rollers: influence of tyre pressure and cross section on power requirements     

Reiser R  Watt J  Peterson M 《Sports biomechanics / International Society of Biomechanics in Sports》2003,2(2):237-249

The resistance against a cyclist while riding on rollers is due mainly to rolling resistance produced by the deformation of the tyre as it rolls against small diameter drums. Resistance is then combined with wheel speed to set power output. The effect of tyre pressure and cross-section on power was investigated by systematically altering the pressure (552 kPa, 690 kPa, and 827 KPa) in a 20c, 23c, 25c, and 28c tyre of the same design while riding at a wheel speed of 45 kph. Average power over 1 minute was measured with a Power Tap Hub (Tune Corporation, Cambridge, Massachusetts, USA) on five occasions. Statistical significance was evaluated at p < 0.05. Power requirements increased significantly with each reduction in tyre pressure for all tyres and pressures except the 25c between 690 and 827 kPa. The 20c tyre required significantly more power from the cyclist at each tested tyre pressure when compared to the other tyres (which were not different from each other). The differences in resistance from tyre size were not observed when ridden on the road. Additionally, a slightly different tyre design from the same manufacturer responded similarly in the 20c, but was significantly different in the 23c size. It was also observed that power requirements increased significantly when both the wheels were ridden on the rollers as compared to just the rear wheel. These results indicate that the power requirements may be significantly altered by the cyclist by adjusting tyre pressure, tyre cross-section size, tyre type, and with the number of wheels contacting the rollers. However, the magnitude of these power requirements may not be suitable for intense workouts of trained cyclists.  相似文献   

Evolution of a veterinary medical library.     

S R Peterson 《Bulletin of the Medical Library Association》1979,67(1):36-41

Planning a new library and developing a book and journal collection for the College of Veterinary Medicine at Iowa State University are described. The Veterinary Medical Library is a self-contained unit (6,800 square feet) for print material within the Veterinary Medical Building. Seating for 140 patrons is available. The collection is designed to provide basic materials for teaching and research in veterinary and comparative medicine. Indexing and abstracting tools permit access to local, state, and national resources as well. At present the collection totals over 17,000 volumes and over 500 serial titles. A working collection of 25,000 volumes will be maintained in the Veterinary Medical Library, and the University Library will continue to function as the principal backup source.  相似文献   

Judgments Regarding Appropriate Child Supervision to Prevent Injury: The Role of Environmental Risk and Child Age   总被引：13，自引：0，他引：13  

Lizette Peterson  Bernard Ewigman  Coleen Kivlahan 《Child development》1993,64(3):934-950

Parents, social service workers, and medical personnel failed to differ in the amount of time they estimated that children of 11 differing ages should be left without adult supervision within 5 different supervision domains. More hazardous circumstances dramatically reduced the amount of time respondents said children should be left unsupervised. Amount of unsupervised time increased with age, with clear developmental cutoffs that varied by level and type of risk. When the moderate center of the distribution was examined, 3 clear areas of consensus emerged. For most domains, constant supervision was recommended for preschool children. For early elementary school children, nearly constant (0–5 min without supervision) or close (0–15 min without supervision) supervision was recommended in safer locations, with constant supervision still recommended in high-risk situations. Only with older children was there an absence of consensus regarding supervision. The implications of these results for future injury prevention research are discussed.  相似文献   

School teachers' control and involvement in their own evaluation     

Kenneth D. Peterson  Tom Chenoweth 《Journal of Personnel Evaluation in Education》1992,6(2):177-190

Summary For the technical, sociological-psychological, and political benefits of teacher participation in evaluation to occur, new structures and policies concerning evaluation must be put into place. Teachers must be given stagewise support in developing increased involvement and control. But finally, those policy makers, evaluation program designers and researchers who plan for teacher evaluation must act to more completely include teachers in their own evaluation. A great deal of good is at stake in the opportunity to increase teacher participation in teacher evaluation.  相似文献
