Psychometric Properties of a Parental Questionnaire for Assessing Correlates of Toddlers’ Physical Activity and Sedentary Behavior     

Valerie Carson  Kylie D. Hesketh  Ryan E. Rhodes  Christina Rinaldi  Wendy Rodgers  John C. Spence 《Measurement in physical education and exercise science》2017,21(4):190-200

This study examined the psychometric properties of a questionnaire developed with the guidance of the socialization model of child behaviour to understand modifiable correlates of toddlers’ physical activity and sedentary behaviour. Findings are based on 118 parents (33.7 ± 4.9 years; 86% female) of toddlers (19.3 ± 2.7 months; 48% female) from Edmonton, Canada in The Parents’ Role in Establishing healthy Physical activity and Sedentary behaviour habits study (PREPS). The PREPS questionnaire encompassed 21 variables across the constructs of the socialization model of child behaviour. Of the nine variables assessed for internal consistency reliability, eight had good (α ≥ 0.70) reliability. Of the 15 continuous variables assessed for 1-week test–retest reliability, 10 had moderate (intra-class correlation = 0.50–0.74) and 5 had good (intra-class correlation ≥ 0.75) reliability. Of the six categorical variables assessed for 1-week test–retest reliability, two had fair (К = 0.21–0.40), one had moderate (К = 0.41–0.60), one had substantial (К = 0.61–0.80), and two had almost perfect (К = 0.81–1.00) reliability. Of the 12 sedentary behaviour variables assessed for convergent validity, 7 were significantly correlated with children’s screen time, of which three were small (r ≤ 0.29), two were medium (r = 0.30–0.49), and two were large (r ≥ 0.50) effect sizes.  相似文献   

Attentional bias for exercise-related images     

Berry TR  Spence JC  Stolp SM 《Research quarterly for exercise and sport》2011,82(2):302-309

This research examined attentional bias toward exercise-related images using a visual probe task. It was hypothesized that more-active participants would display attentional bias toward the exercise-related images. The results showed that men displayed attentional bias for the exercise images. There was a significant interaction of activity level by gender, and simple slopes analysis showed that active women displayed attentional bias toward the exercise-related images and inactive women displayed attentional bias toward the control images. A similar analysis with explicit attention to the pictures as the outcome variable was not significant. These findings confirm that attention for exercise-related images can be captured automatically regardless of whether people report they are attending to them.  相似文献

IP Address Data and its Place in the Library Community Today and in the Future     

Justin R. Spence  Andrew Pitts  Ian Hames 《期刊图书馆员》2017,73(3-4):296-304

Internet Protocol (IP) technology has played an important role in the management of access to scholarly work within institutions since the advent of electronic publishing in the late 1990s. Despite recent efforts to explore alternative modes of authentication, the ubiquitous use of IP address authentication within the systems of libraries, publishers, and third party vendors around the world suggests it will continue to play a significant role for the foreseeable future. However, recent studies show that a large amount of the IP address data held within publisher systems is incorrect, improperly assigned, or requires clarification. Poor source data carries significant risks—not the least of which translates into unreliable usage reporting for libraries and publishers. The IP Registry is designed to help mitigate these challenges by creating a Registry of cleaned data that libraries and publishers can interact with in a centralized fashion thereby helping to ensure accuracy and reducing the level of resources necessary to manage and communicate changes to existing data. The database of more than 60,000 academic, corporate, and government libraries was created through the amalgamation of raw source data from more than 170 scholarly publishers. In addition to cleaned IP address data, the Registry includes standardized English naming, aliases, local language naming (and characters), hierarchies, and organizational IDs for each record. The importance of accurately understanding current usage and how libraries utilize published content is clear. Regardless of what the future holds, the need for a clean and stable source of IP address data is real for libraries, publishers, and vendors alike.  相似文献   

Play and Divergent Problem Solving: Evidence Supporting a Reciprocal Relationship     

Shirley R. Wyver  Susan H. Spence 《Early education and development》1999,10(4):419-444

A series of three studies was conducted to examine the relationship between specific forms of social and pretend play and divergent (figural and semantic) and convergent problem solving in preschool aged children. Naturalistic and experimental designs were used to provide a clearer account of the nature of the relationship between play and problem solving and to challenge the assumption that there is a single direction bf influence (play influencing problem solving) rather than the influence being complex and reciprocal. Overall, the results support a complex reciprocal causality model in which the development of divergent problem solving skills facilitates the development of play skills and vice versa.  相似文献   

Seasonal variation in physical activity among preschool children in a northern Canadian city     

Carson V  Spence JC  Cutumisu N  Boule N  Edwards J 《Research quarterly for exercise and sport》2010,81(4):392-399

Little research has examined seasonal differences in physical activity (PA) levels among children. Proxy reports of PA were completed by 1,715 parents on their children in Edmonton, Alberta, Canada. Total PA (TPA) minutes were calculated, and each participant was classified as active, somewhat active, or inactive. Logistic regression models were conducted to examine associations between PA status and seasons. Significant seasonal differences were observed for TPA, weekday PA, weekend PA, and active play. Children were significantly more likely to be physically active in the summer and spring and somewhat physically active in the summer and fall, relative to winter Children living in cold climates are less likely to be physically active in the winter.  相似文献   

The Same But Different: Standardizing Interview Procedures in the Multinational     

Laura J. Spence 《Performance Improvement Quarterly》2000,13(2):43-55

In this paper, the reality of attempted standardization of recruitment interviewing in a multinational company is presented. The focus in this instance is on recruitment in a single multinational in three superficially similar North European countries: the Netherlands, the UK, and Germany. The organization on which the study was based wanted to improve the diversity of its recruitment and offer fair opportunities to all. The results of this study indicate that any standardization of procedures in multinationals must take into account the influence of cultural differences in implementation. On the basis of the case presented here, the Dutch will implement procedures precisely as a matter of compliance and fairness on a social contract basis; the Germans will emphasize the discourse around standard procedure implementation and want to ensure a full and thorough discussion; and Britons will take a pragmatic approach with procedures seen as recommended guidelines only. The implications of the findings for the case study company and its efficiency in recruiting diverse individuals are discussed.  相似文献   

Children's Perception of Proportion in Graphs     

Ian Spence  Peter Krizel 《Child development》1994,65(4):1193-1213

Children ranging in age from 9 to 13 years made judgments of proportion with a variety of graphical elements in 2 experiments. Younger children can be misled by irrelevant dimensions of objects used to portray magnitudes and proportions, but older children make their judgments like adults, ignoring or accommodating the extra dimensions. Although the psychophysical function for older children and adults is approximately linear, closer inspection reveals a complex pattern of bias that is not captured by traditional psychophysical models. A characteristic pattern of over- and underestimation was observed and also turns out to be present, but previously unnoticed, in judgments made by adults. The pattern of bias is consistent with the view that the visual system extracts real or virtual axes of symmetry and that subjects use these, in addition to the object boundaries, as points of reference when making their judgments. A model that assumes repulsion of judgments away from these reference points is described and fitted to the children's data. The model is motivated by both neurophysiological and cognitive considerations.  相似文献   

Using continuous assessment to promote student engagement in a large class     

Jonathan S. Cole  Stephen W.T. Spence 《European Journal of Engineering Education》2012,37(5):508-525

The authors have developed a first-year fluids course for a class of around 230 aerospace, civil and mechanical engineering students. This paper aims to show how the teaching and assessment methodology was applied to the challenge of a large class. The lectures featured formal teaching interspersed with active learning elements. Smaller group (about 25–30 students) tutorial classes involved student practice. A 10-minute test occurred in each tutorial during weeks 3–11. Each test was based on the previous week's lecture material and the marks contributed towards 20% of the course mark. A condition for passing the course was that a student must pass at least six of the nine tests. The assessment promoted student involvement with the course – tutorial attendance was greater and more uniform than previously and exam performance improved significantly. Students recognised that the assessment system was useful in encouraging continuous learning over the semester and building confidence.  相似文献
