This research compares the industry readiness, product development skill level, and overall knowledge gains of students taking an undergraduate research course (treatment) to those who did not (control). This 2‐semester Applied Interdisciplinary Product Development (AIPD) course for sophomores brought together interdisciplinary teams of food science, nutrition, and packaging science students in a hands‐on setting to create healthy food products for children, complete with retail packaging. A Subject Knowledge Assessment (SKA) was used to evaluate the mean percent difference value (MPDV) of food science, nutrition, packaging science, and general product development knowledge gained through the course. SKA results indicated that the MPDV were significantly different (α = 0.05) between the treatment and comparison groups in the overall score and in every subject area score except packaging science. Data from an Exit Questionnaire (EQ) was used for evaluation of attitudes pertaining to product development knowledge and skills, department engagement, and pedagogy. EQ results indicated that mean scores between the treatment and comparison groups were significantly different (α = 0.05) in 7 of the 9 statements on product development knowledge and skills, both statements pertaining to pedagogy, and the statement pertaining to department engagement. Overall, the research project was considered a successful intervention for educating sophomores at the University. Overall, the research project was considered a successful intervention for educating sophomores in the Food, Nutrition and Packaging Science department at Clemson University. The student‐lead teams were held to a greater degree of accountability for their success in terms of education gleaned and value of experience gained as metric for the University and other IFT Accredited programs.  相似文献   

The biggest extension of rights in Europe? Needs,rights and children with additional support needs in Scotland     

Sheila Riddell  Duncan Carmichael 《International Journal of Inclusive Education》2019,23(5):473-490

ABSTRACT

The Education (Additional Support for Learning) (Scotland) Act 2004 boosted the rights of parents of children with additional support needs (ASN) by improving access to information, instituting a Code of Practice and establishing new redress mechanisms such as the ASN Tribunal and independent mediation. More than a decade later, Scottish legislation enacted in 2016 and implemented in 2018 attempted to increase children’s rights, broadly placing them on a par with those of parents and young people. This paper draws on data from an ESRC project entitled Autonomy, Rights and Children with Special Needs: A New Paradigm? (ES/P002641/1). Analysis of Scottish Government policy and legislation, key informant interviews and official statistics are used to examine the extent to which the new rights are likely to be realised in practice, given the complexity of the legislation and competition between discourses of needs, broadly synonymous with the wellbeing agenda and rights. The paper concludes with a discussion of the lessons which may be learnt from the Scottish experience, which will be of interest to an international audience.  相似文献   

The Structure of Achievement and Behavior across Middle Childhood     

Lori Kowaleski-Jones  & Greg J. Duncan 《Child development》1999,70(4):930-943

This research used data from the National Longitudinal Survey of Youth (NLSY) to describe and model developmental trajectories across middle childhood. Our sample consisted of approximately 1,000 children of NLSY women who were aged 6 to 7 years in either 1986 or 1988. Assessments of PIAT math and reading scores and the mother-reported Behavior Problem Index in 1986, 1988, 1990, and 1992 provided data for middle-child trajectories of children aged 6 to 7 in 1986. Assessments in 1988, 1990, 1992, and 1994 provided data for children aged 6 to 7 in 1988. We used the raw score form of these data to estimate LISREL-based models of their autoregressive structure. As with other samples, average math and reading achievement trajectories were parabolic for NLSY children, with scores increasing at a decreasing rate over this period. Average behavior-problem trajectories were flat. Behind these average shapes was extreme diversity in level (and in some cases, slopes), of individual trajectories and a pronounced tendency for above average changes between two adjacent assessments to be followed by opposite-signed changes in the subsequent period. Estimates from our structural models showed great heterogeneity in the average level of achievement and behavior for all three outcomes and heterogeneous slopes for reading scores as well. Boys but not girls were found to have heterogeneous slopes for math and behavior problems, whereas girls but not boys showed a significantly higher degree of persistence if "shocked" off of their expected trajectories.  相似文献   

Lower leg and foot contributions to turnout in female pre-professional dancers: A 3D kinematic analysis     

Sarah L. Carter  Rebekha Duncan  Andries L. Weidemann  Luke S. Hopper 《Journal of sports sciences》2018,36(19):2217-2225

Turnout is a central element of classical ballet which involves sustained external rotation of the lower limbs during dance movements. Lower leg and foot compensation mechanisms which are often used to increase turnout have been attributed to the high incidence of lower limb injury in dancers. Evaluation of dancers’ leg posture is needed to provide insight into the lower limb kinematic strategies used to achieve turnout. The primary purpose of this study was to use 3D kinematic analyses to determine the lower leg and foot compensations that are incorporated by female university dancers to accentuate their turnout. Active and passive external tibiofemoral rotation (TFR) was also measured. A moderate-strong negative relationship was observed between hip external rotation (HER) and foot abduction in the three first position conditions. A moderate negative relationship was found between passive TFR and foot abduction in all first position conditions. Our findings suggest dancers are more likely to pronate, than rotate the knee to compensate for limited HER. Dancers with a limited capacity to pronate may force additional rotation via the knee. Ongoing research would benefit from more in-depth analyses of the foot/ankle complex using a multi-segment foot model.  相似文献   

The one-week and six-month reliability and variability of three-dimensional tibial acceleration in runners*     

Kelly R. Sheerin  Thor F. Besier  Duncan Reid  Patria A. Hume 《Sports biomechanics / International Society of Biomechanics in Sports》2018,17(4):531-540

Tibial acceleration is a surrogate measure for impact loading and lower limb fatigue injury in runners. Triaxial accelerometers may offer reliable and practical measurement of resultant peak tibial acceleration (PTA). With such potential in mind, this study examined variability and measurement reliability of tibial acceleration in 14 runners at baseline at one week, and eight of the runners again at six months. Triaxial accelerometers were attached to the distal tibiae of runners before they ran on a treadmill for two minutes each, at speeds of 2.7, 3.0, 3.3 and 3.7 m/s in standardised shoes. Resultant PTAs were calculated for each speed and session. Reliability outcomes were presented as percentage change and effect sizes. Variability outcomes included intraclass correlation coefficients and the typical error of the measurement. Smallest worthwhile change and performance/noise ratio were also calculated. While runners demonstrated marginally lower reliability and higher variability over six months, compared to one week, in all cases the measures of reliability and variability were of ‘good’ to ‘moderate’ reliability, and ‘small’ to ‘moderate’ variability using magnitude-based inferences. We can be confident that resultant PTA can be used with runners to assess and monitor their impacts throughout a six-month intervention.  相似文献   

A Latent Growth Curve Approach to Investigating Developmental Dynamics and Correlates of Change in Children's Perceptions of Physical Competence     

Terry E. Duncan  Susan C. Duncan 《Research quarterly for exercise and sport》2013,84(4):390-398

Abstract

In both the physical and academic domains interest has recently grown regarding developmental change in children's perceptions of competence. Recent advances in statistical methodology, such as latent growth modeling, enable the researcher to analyze developmental trends from both an inter- and intraindividual perspective, thus serving to increase our understanding of correlates of change in perceived competence. Using latent growth modeling, the purpose of the present study was to investigate developmental change in children's perceived competence at physical skills, examining maturational factors and chronological age as possible correlates of change. Subjects were male adolescents (N = 94). Data were collected during the child's sixth, eighth, and ninth grade school years. Results revealed a good fit for the hypothesized model, which specified mean level changes in the variables over time and an interrelationship among the latent chronometric common factors. Although a significant relationship existed between maturation and perceived competence, no significant relationship was evident between chronological age and perceived competence. Findings are discussed with particular reference to the utility of latent growth curve models for assessing developmental processes at both the inter- and intraindividual level.  相似文献   

The Cups That Cheered – A History of the Sigerson,Fitzgibbon and Higher Education Gaelic Games     

Mark Duncan 《国际体育史杂志》2013,30(17):2121-2123

This article follows up on Adrian Harvey's piece ‘The emergence of football in nineteenth-century England: the historiographic debate’ [International Journal of the History of Sport 30, no. 18 (2013): 2154–2163]. It reviews the historiography of Scottish football on the period before the First World War. There is considerable literature on the topic, but it is not by any means evenly distributed to cover Scotland's geography, nor does it give balanced coverage to a wide-enough variety of thematic subjects. The author places this historiography into six broad categories which reflect the audience, research interests and methodology of the pieces, and offers a critical assessment of work still to be done in what is a disparate field.  相似文献
