This study investigates whether educators’ cognitive and structural social capital is associated with perceptions of innovative climate in charter schools. We explore a new concept to assess educators’ cognitive social capital, namely network intentionality, meaning the extent to which an educator is intentional in connecting and interacting with others. We hypothesize that network intentionality (cognitive social capital) is related to the extent to which educators perceive their school’s climate to be innovative, but that this relationship is dependent on the educator’s position in their school’s social network (structural social capital). Findings suggest that the relationship between cognitive social capital and perceptions of innovative climate is partly mediated by structural social capital. In other words, those educators with high network intentionality, as evidenced by an orientation towards connecting others, also perceive the school’s climate as being more innovative, partly because this strong network intentionality is associated with more out-going relational activity. This work provides unique insights into the factors that may be associated with teacher collaboration in successful charter schools serving traditionally underserved populations, and suggests ideas for schools wishing to support teacher collaboration and innovation.  相似文献   

The use of query suggestions during information search     

Xi Niu  Diane Kelly 《Information processing & management》2014

Query suggestion is a common feature of many information search systems. While much research has been conducted about how to generate suggestions, fewer studies have been conducted about how people interact with and use suggestions. The purpose of this paper is to investigate how and when people integrate query suggestions into their searches and the outcome of this usage. The paper further investigates the relationships between search expertise, topic difficulty, and temporal segment of the search and query suggestion usage. A secondary analysis of data was conducted using data collected in a previous controlled laboratory study. In this previous study, 23 undergraduate research participants used an experimental search system with query suggestions to conduct four topic searches. Results showed that participants integrated the suggestions into their searching fairly quickly and that participants with less search expertise used more suggestions and saved more documents. Participants also used more suggestions towards the end of their searches and when searching for more difficult topics. These results show that query suggestion can provide support in situations where people have less search expertise, greater difficulty searching and at specific times during the search.  相似文献   

Learning from Non-Reported Data: Interpreting Missing Body Mass Index Values in Young Children     

Kelly P. Arbour-Nicitopoulos  Guy E. Faulkner  Scott T. Leatherdale 《Measurement in physical education and exercise science》2013,17(4):241-251

The objective of this study was to examine the pattern of relations between missing weight and height (BMI) data and a range of demographic, physical activity, sedentary behavior, and academic measures in a young sample of elementary school children. A secondary analysis of a large cross-sectional study, PLAY-On, was conducted using self-reported data from a convenience sample of fifth- to eighth-grade students (9–14 years) attending 30 elementary schools in Ontario, Canada. Items assessed related to demographics (age, gender, and ethnicity), physical activity (energy expenditure, location, and sport participation), sedentary behavior (communication and screen-time), and academics. Of the 2,111 children who were included in the analyses, 960 (45.5%) were missing BMI data. Children without BMI data were more likely to be younger, female, of non-white ethnicity, have lower daily energy expenditure values, not participate in school sports, and have lower-rated academic standing than those children with BMI data. Overall, this study demonstrates characteristics of children who fail to self-report their height or weight. The trend for younger children to be more likely to fail to report BMI suggests that some children may be unmotivated non-responders. Meanwhile, the trend for girls to be more likely to fail to report weight than boys indicates that some girls may be motivated non-responders. Self-report BMI might include too much missing data to be effective for determining children's progress toward previously established targets for intervention and surveillance efforts.  相似文献   

Habituation of 10-year-old hockey players to treadmill skating     

Kelly L. Lockwood  Gail Frost 《Sports biomechanics / International Society of Biomechanics in Sports》2013,12(2):145-154

This study assessed changes in selected physiological and kinematic variables over 6 weeks of treadmill skating in an effort to understand the process of habituation to this novel training modality. Seven male, Atom-A hockey players who were injury-free and had no previous treadmill skating experience participated in the study. Players performed four 1-min skating bouts at progressively increasing speeds, each week, for 6 weeks. One speed (10.5 km/h) was repeated weekly to allow for assessment of the habituation process. Our criteria for habituation were: a decrease in stride rate, heart rate and rating of perceived exertion, and an increase in stride length, trunk angle and vertical movement of the centre of mass, leading to a plateau, over the course of the 6-week study. Significant decreases were seen in stride rate, heart rate and ratings of perceived exertion, and significant increases were found in stride length. Some of these changes were evident after only one week of training and all were present by week 4. After 6 weeks (24 min) of exposure to treadmill skating, all participants displayed a visibly more efficient skating style.  相似文献   

Physical Therapists’ Perceptions of Knowledge and Clinical Behavior Regarding Cardiovascular Disease Prevention     

R Scott Van Zant  Kelly Jo Cape  Katrina Roach  Janie Sweeney 《Cardiopulmonary Physical Therapy Journal》2013,24(2):18-26

Purpose

The study purpose was to assess perceptions of physical therapists (PTs) regarding the role of physical therapy in cardiovascular disease (CVD) prevention.

Methods

A 25-item survey, validated by expert cardiovascular/pulmonary (CVP) PTs, was sent electronically to 2,673 PTs. Each item represented an element of clinical practice behavior: education of CVD/risk factors (EDCVD), administration of primary CVD prevention (PRECVD), identifying underlying CVD/risk factors (IDCVD), monitoring CV status in patients with CVD (MONCVD). Responses were assigned numeric values (strongly agree = 5 to strongly disagree = 1), and mean element scores were analyzed.

Results

Most of the 516 respondents were APTA Section members (34% CVP Section, 42% other Section membership) and worked in academia (53%). Items showing a high (> 95%) level of agreement included patient education of smoking (97%) and monitoring exercise intensity (99%), assessing exercise benefits (99%), clinically identifying obesity (97%) and hypertension (97%), and monitoring CV response to exercise (99%). Items failing to reach 80% overall agreement were patient education of CVD medications (79%) and blood chemistry (72%), and assessing CVD family history (75%), patient BMI (60%), and body composition (33%). Identifying underlying CVD (77.2%) was the only practice behavior failing to reach 80% agreement. Outpatient PTs agreed significantly less to all elements vs. academics, and to IDCVD vs. all PTs except home health.

Conclusions

Physical therapists support most CVD prevention behaviors, but not given elements of patient education and identifying underlying CVD/risk factors.Key Words: cardiovascular disease, primary disease prevention, secondary disease prevention  相似文献   

Skills, capabilities and inequalities at school entry in a disadvantaged community     

Orla Doyle  Louise McEntee  Kelly A. McNamara 《European Journal of Psychology of Education - EJPE》2012,27(1):133-154

Socioeconomic inequalities in children’s skills and capabilities begin early in life and can have detrimental effects on future success in school. The present study examined the relationships between school readiness and socioeconomic (SES) inequalities using teacher reports of the Short Early Development Instrument (Janus et al. 2005) in a disadvantaged urban community of Ireland. It specifically examined differences in skills within a low SES community in order to investigate the role of relative disadvantage on children’s development. SES differences across multiple domains of school readiness were examined using Monte Carlo permutation tests and seemingly unrelated regression models. The false discovery rate (Benjamini and Hochberg 1995) was used to control for multiple hypothesis testing. The results indicated that being from a relatively higher SES background does not act as a protective factor for children residing in a disadvantaged community for the majority of school readiness domains. This implies that the neighbourhood may play a role in children’s school readiness skills. These results suggest that school readiness interventions should target all children living in disadvantaged communities as each child may be at risk of poor school readiness.  相似文献   

Primary prevention of pediatric abusive head trauma: A cost audit and cost-utility analysis     

Joshua Friedman  Peter Reed  Peter Sharplin  Patrick Kelly 《Child abuse & neglect》2012,36(11-12):760-770

ObjectivesTo obtain comprehensive, reliable data on the direct cost of pediatric abusive head trauma in New Zealand, and to use this data to evaluate the possible cost–benefit of a national primary prevention program.MethodsA 5 year cohort of infants with abusive head trauma admitted to hospital in Auckland, New Zealand was reviewed. We determined the direct costs of hospital care (from hospital and Ministry of Health financial records), community rehabilitation (from the Accident Compensation Corporation), special education (from the Ministry of Education), investigation and child protection (from the Police and Child Protective Services), criminal trials (from the Police, prosecution and defence), punishment of offenders (from the Department of Corrections) and life-time care for moderate or severe disability (from the Accident Compensation Corporation). Analysis of the possible cost-utility of a national primary prevention program was undertaken, using the costs established in our cohort, recent New Zealand national data on the incidence of pediatric abusive head trauma, international data on quality of life after head trauma, and published international literature on prevention programs.ResultsThere were 52 cases of abusive head trauma in the sample. Hospital costs totaled $NZ2,433,340, child protection $NZ1,560,123, police investigation $NZ1,842,237, criminal trials $NZ3,214,020, punishment of offenders $NZ4,411,852 and community rehabilitation $NZ2,895,848. Projected education costs for disabled survivors were $NZ2,452,148, and the cost of projected lifetime care was $NZ33,624,297. Total costs were $NZ52,433,864, averaging $NZ1,008,344 per child. Cost-utility analysis resulted in a strongly positive economic argument for primary prevention, with expected case scenarios showing lowered net costs with improved health outcomes.ConclusionsPediatric abusive head trauma is very expensive, and on a conservative estimate the costs of acute hospitalization represent no more than 4% of lifetime direct costs. If shaken baby prevention programs are effective, there is likely to be a strong economic argument for their implementation. This study also provides robust data for future cost–benefit analysis in the field of abusive head trauma prevention.  相似文献   

A design-based research case study documenting a constructivist ID process and instructional solution for a cross-cultural workforce     

Monica W. Tracey  Kelly L. Unger 《Instructional Science》2012,40(3):461-476

As the need for instructing a globalized workforce increases, instructional designers must embrace the constraints and the opportunities these projects provide in order to move the field of cross-cultural instructional design (ID) forward. Cross-cultural projects offer multiple avenues for growth in ID practice, overcoming cultural barriers, and a venue to apply and test contemporary models, methodologies, and theories in ID. This design-based research case study employed a rapid prototyping methodology and the constructivist ID model, Layers of Negotiation, to collect critical cultural information for the design of this cross-cultural instruction. Instructional strategies deemed effective for instructing an unskilled workforce in Dubai, United Arab Emirates, included job aids, situated learning and apprenticeship principles consisting of modeling, coaching and scaffolding. Use of the constructivist ID model and instructional solution for a cross-cultural workforce for The Dubai Mall are presented. Evaluation results indicate the success of the instructional strategies varied dependent upon worker culture, and the sequential nature of the instructional strategies.  相似文献   

A Study of Gender Differential Linguistic Interaction in the Adult Classroom     

Jean Kelly 《Gender and education》1991,3(2):137-143

This article attempts to determine whether men dominate the language in the mixed‐gender adult classroom. Form‐based and activity‐based research methods were used with a group of adults on a training project at Cranford Community School in the London Borough of Hounslow. The findings were related to some of the relevant literature on the linguistic domination of boys in the school classroom and an attempt was made to establish whether men use the same devices to control the language in adult learning situations.  相似文献
