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   

FAST-Future Academic Scholars in Teaching: A High-Engagement Development Program for Future STEM Faculty     

Claudia E. Vergara  Mark Urban-Lurain  Henry Campa III  Kendra S. Cheruvelil  Diane Ebert-May  Cori Fata-Hartley  Kevin Johnston 《Innovative Higher Education》2014,39(2):93-107

Doctoral granting institutions prepare future faculty members for academic positions at institutions of higher education across the nation. Growing concerns about whether these institutions are adequately preparing students to meet the demands of a changing academic environment have prompted several reform efforts. We describe a professional development model designed to prepare the future faculty to integrate the multiple components of academic careers. The program emphasizes the study and application of effective teaching practices centered on student learning and assessment and expectations for faculty careers. We describe the impact of the program on its participants.  相似文献   

Assessment of Student Learning Associated with Tree Thinking in an Undergraduate Introductory Organismal Biology Course     

James J. Smith  Kendra Spence Cheruvelil  Stacie Auvenshine 《CBE life sciences education》2013,12(3):542-552

Phylogenetic trees provide visual representations of ancestor–descendant relationships, a core concept of evolutionary theory. We introduced “tree thinking” into our introductory organismal biology course (freshman/sophomore majors) to help teach organismal diversity within an evolutionary framework. Our instructional strategy consisted of designing and implementing a set of experiences to help students learn to read, interpret, and manipulate phylogenetic trees, with a particular emphasis on using data to evaluate alternative phylogenetic hypotheses (trees). To assess the outcomes of these learning experiences, we designed and implemented a Phylogeny Assessment Tool (PhAT), an open-ended response instrument that asked students to: 1) map characters on phylogenetic trees; 2) apply an objective criterion to decide which of two trees (alternative hypotheses) is “better”; and 3) demonstrate understanding of phylogenetic trees as depictions of ancestor–descendant relationships. A pre–post test design was used with the PhAT to collect data from students in two consecutive Fall semesters. Students in both semesters made significant gains in their abilities to map characters onto phylogenetic trees and to choose between two alternative hypotheses of relationship (trees) by applying the principle of parsimony (Occam''s razor). However, learning gains were much lower in the area of student interpretation of phylogenetic trees as representations of ancestor–descendant relationships.  相似文献   

Being First Means Being Credible? Examining the Impact of Message Source on Organizational Reputation     

Patric R. Spence  Kenneth A. Lachlan  Leah M. Omilion-Hodges  Amanda K. Goddard 《Communication Research Reports》2013,30(1):124-130

Research in organizational communication and public relations suggest that in times of crises, messages generated by the organization are most likely to positively influence stakeholder perceptions, whereas those generated by the press may have negative ramifications. Although this advice seems logical, to date there is little research that investigates this claim empirically and directly. Two experiments were conducted to explore the separate and combined impact of print and televised messages concerning an organization in the midst of a crisis. The findings offer empirical evidence that statements from organizations experiencing crises may offset negative stakeholder responses. Theoretical and pragmatic implications are discussed regarding these findings.  相似文献   

Library Collections for the Support of Academic Sport Management Programs     

Kendra Spahr  Stephanie Wiegand 《Journal of Business & Finance Librarianship》2013,18(3):220-241

Sport management is a relatively new and rapidly growing academic discipline. Despite the proliferation of sport management programs in the United States, a review of the library literature reveals few publications concerning library support for such programs. In addition to providing background knowledge about the sport management discipline, this article provides practical information for academic librarians by recommending essential databases, journals, academic publishers, industry publishers, and associations in the arena of sport management.  相似文献   

Redefinition,Differentiation, and the Farm Animal Welfare Debate     

Kendra Lancaster & Josh Boyd 《Journal of Applied Communication Research》2013,41(2):185-202

Animal welfare advocates have increased publics' scrutiny of the way animals are handled by everyone from pet owners to circuses to farmers. The case of farmer Gary Conklin illustrates a popular recent tactic of activists to secretly film working farms and then release videos that purport to show abuse. This essay uses the concepts of legitimacy and image restoration to examine how Conklin, with a small farming operation in Ohio, responded to allegations spread by social media. Two important principles emerged: first, an effective differentiation strategy for reducing offensiveness is “redefining the act,” a combination of image repair tactics where an undisputed fact is redefined and transformed with support from third-party affirmations. Second, even small organizations like this dairy cattle business face the same challenges and opportunities as larger organizational rhetors. The essay concludes with applications both for agriculture and for crisis communication scholars, asserting that agricultural enterprises will continue to face struggles over meaning that will require sophisticated methods of issue and crisis management.  相似文献
