Tests of alignment among assessment,standards, and instruction using generalized linear model regression     

Gavin W. Fulmer  Morgan S. Polikoff 《Educational Assessment, Evaluation and Accountability》2014,26(3):225-240

An essential component in school accountability efforts is for assessments to be well-aligned with the standards or curriculum they are intended to measure. However, relatively little prior research has explored methods to determine statistical significance of alignment or misalignment. This study explores analyses of alignment as a special case of the generalized linear model (GLM). A general approach for such analyses is suggested, and examples are given for analyses with traditional alignment and GLM regression using data from two previously published studies. Results from the GLM are compared with ordinary least squares (OLS) regression. Findings show that the GLM method allows more informative analysis of differences between source documents than alignment indices alone, including determination of whether marginal discrepancies are statistically significant or not.  相似文献   

Do Tiers Affect Student Transfer? Examining the Student Admission Ratio     

Gavin Moodie 《Community College Journal of Research & Practice》2013,37(11):847-861

This study considers whether formally segmenting 4-year institutions by admissions selectivity affects the admission of transfer students. It develops a new measure, the student admission ratio, to compare the admission of transfer students in formally and highly segmented systems, informally and less segmented systems, and in formally unified systems. The study finds that the segmentation of systems by admissions selectivity does not adversely affect transfer admissions. The study concludes by positing that the formal structure of a system is not so important for student transfer as the processes for implementing transfer policy, and it considers the implications of this for practice.  相似文献   

Lactate accumulation following isometric exercise training and its relationship with reduced resting blood pressure     

Gavin R. Devereux  Damian Coleman  Jonathan D. Wiles  Ian Swaine 《Journal of sports sciences》2013,31(11):1141-1148

Abstract

The purpose of this study was (a) to assess lactate accumulation during isometric exercise, and to quantify the shifts in accumulation following isometric training; and (b) to relate any training-induced changes in lactate accumulation to reductions in resting blood pressure. Eleven male participants undertook isometric training for a 4-week period using bilateral-leg exercise. Training caused reductions in systolic, diastolic, and mean arterial resting blood pressure (of ?4.9 ± 6.3 mmHg, P = 0.01; ?2.6 ± 3.0 mmHg, P = 0.01; and ?2.6 ± 2.3 mmHg, P = 0.001 respectively; mean ± s). These were accompanied by changes in muscle activity, taken as electromyographic activity to reach a given lactate concentration (from 114 ± 22 to 131 ± 27 mV and from 136 ± 25 to 155 ± 34 mV for 3 and 4 mmol · L^?1 respectively. Training intensity expressed relative to peak lactate was correlated with reduced resting systolic and mean arterial blood pressure. Training caused significant shifts in lactate accumulation, and reductions in resting blood pressure are strongly related to training intensity, when expressed relative to pre-training peak lactate. This suggests that higher levels of local muscle anaerobiosis may promote the training-induced reductions in resting blood pressure.  相似文献   

Effects of short-term exercise training on tissue Doppler indices of left ventricular diastolic function in overweight and obese individuals     

Aletta Millen  Gavin Norton  Ingrid Avidon 《Journal of sports sciences》2013,31(5):487-499

Abstract

Although exercise training is unable to improve obesity-associated decreases in left ventricular (LV) diastolic function, as assessed using chamber function measurements, the effects on LV diastolic myocardial function, as assessed using tissue Doppler imaging (TDI), are uncertain. In 32 overweight (n = 11) or obese (n = 21), sedentary or recreationally active men and women (30–57 years), we assessed the effects of 6 weeks of exercise training either preceded (n = 16) or followed (n = 16) by a 6-week control period on TDI indices of LV diastolic function (e', e'/a' and E/e') (echocardiography). Diastolic function at baseline was comparable to that noted in overweight and obese participants from a community sample (n = 245), and 56% (n = 18) had e' values below the lower 95% CI of a lean and healthy cohort (n = 60) of the community sample. Exercise training increased peak oxygen consumption (27.4 ± 4.9 to 29.4 ± 5.8 mL · kg^–1 · min^–1, P = 0.0001), but had no effect on body mass index (P = 0.99). No changes in TDI indices of diastolic function were observed after exercise training in all the participants (e': P = 0.74, a': P = 0.98, e'/a': P = 0.85, E/e': P = 0.26), participants with abnormal e' values (n = 18)(e': P = 0.99, a': P = 0.96, e'/a': P = 0.91, E/e': P = 0.97) or obese participants (n = 21)(e': P = 0.67, a': P = 1.00, e'/a': P = 0.78, E/e': P = 0.11). In conclusion, exercise training, despite increasing cardiorespiratory fitness, is unable to improve obesity-associated decreases in LV diastolic myocardial function.  相似文献   

The effects of a single night of complete and partial sleep deprivation on physical and cognitive performance: A Bayesian analysis     

Tom Cullen  Gavin Thomas  Alex J. Wadley  Tony Myers 《Journal of sports sciences》2013,31(23):2726-2734

ABSTRACT

This study investigated the effects of complete and partial sleep deprivation on multiple aspects of athletic performance. Ten males completed a cognitive function test, maximal handgrip strength, countermovement jump (CMJ) and a 15 min all out cycling test to assess aerobic performance. These tests were performed following 3 different sleep conditions; normal sleep (CON), a 4 hr sleep opportunity (PART) and complete sleep deprivation (DEP). Data were analysed using a Bayesian multi-level regression model to provide probabilities of impairment (p = %). Aerobic performance, CMJ and handgrip strength were impaired by 11.4% (p = 100%), 10.9% (p = 100%) and 6% (p = 97%) following DEP, while aerobic performance and CMJ were highly likely impaired by 4.1% (p = 90%) and 5.2% (p = 94%) following PART. Cognitive reaction time was not impacted by PART or DEP. In contrast the accuracy of responses was highly likely impaired by 2% (91) following DEP, while there was less certainty of impaired accuracy following PART (?1%, p = 73). Multiple aspects of physical and cognitive performance were impacted by sleep deprivation. The greatest detrimental effects were seen for aerobic performance and CMJ. Partial sleep deprivation equating to 4 hrs of sleep causes subtle, but potentially important negative impairments on athletic performance.  相似文献   

How can organisations learn: an information systems development perspective     

Gavin J. Baxter  Thomas M. Connolly  Mark Stansfield 《Learning Inquiry》2009,3(1):25-46

This article sets out to argue that organisations can learn but that they cannot do so in their own right without infrastructural support. This article further examines the notion that individuals in organisations also require the cognitive participation of the organisation itself as a learning entity to learn. The close reliance and affiliation required between individuals and organisations to enable their learning from one another are discussed. In continuation of this, specific examples are provided through the industry sector of information systems development (ISD) projects to illustrate of how organisations can learn. Finally, the question of how one identifies organisational learning is analysed. Following on from the ISD and its use in the analogy of organisational learning, the article discusses an organisational empirical research project currently being undertaken by the authors, which utilises blogs. Though there are many potential organisational learning connotations associated with blogs, they could be perceived as a type of information system. The ongoing research being undertaken with the company using the blogs will attempt to identify indicators of learning at the individual, group and organisational levels. The significance of the issues explored in this article lies in the fact that it addresses an ISD approach to study how an organisation learns, and why this perspective is useful towards understanding the process of organisational learning. This article contributes to the organisational learning debate through an illustrative industry example of ISD projects. In doing so, we wish to argue that though individual learning can occur in ISD projects, the collective nature of projects primarily engenders the interpretive aspect of organisational learning. We further believe that it is the interactive nature of an ISD project that allows an organisation to learn in tandem with project members as exemplified through the stages of a project life cycle. We feel that this article contributes to the ISD and organisational learning literature in terms of linking both concepts together.  相似文献   

Using practical philosophy to enhance the self-regulation of children in secure accommodation     

Gavin Heron  Claire Cassidy 《Emotional and Behavioural Difficulties》2018,23(3):254-269

Secure accommodation provides extreme forms of control and support for a small minority of society’s most vulnerable children. Within such environments it is unclear how children exhibit or develop self-regulation when external controls affect every aspect of day-to-day life. This study provides an insight into self-regulation by examining children’s adherence to the rules associated with a practical form of philosophy, namely Community of Philosophical Inquiry (CoPI). Data was collected from a series of CoPI sessions which took place in secure accommodation and a thematic analysis was used to identify key themes emerging from participant’s rule-adherence. The findings suggest that argumentative dialogue allows children to demonstrate self-regulation in relation to the CoPI rules, although it is often sporadic and variable between individuals. Whilst encouraging argumentation and dialogue can seem counterintuitive, it might promote more adaptive behaviours, which will give children in secure accommodation greater control over their lives.  相似文献   

The perceptions and experiences of young people with a BESD/SEMH classification     

Emma L Sheffield  Gavin Morgan 《Educational Psychology in Practice》2017,33(1):50-64

Social, Emotional and Mental Health (SEMH) needs, previously Behavioural, Emotional and Social Difficulties (BESD), is the most frequently occurring category of Special Educational Need (SEN) in secondary schools in England, associated with school exclusion and poorer outcomes in later life. This study explores the perceptions of young people of the “label” BESD/SEMH and their school experiences. A social constructionist grounded theory approach was used to analyse data from semi-structured interviews with nine young people with a statement of SEN for BESD. Findings show that eight of the participants were previously unaware of their classification of BESD and that it was predominantly negatively evaluated. The grounded theory model arising from the research describes the perceptions of young people of the struggles and strengths that they experience at school. Teacher–pupil relationships were found to contribute to both strengths and struggles at school depending on their perceived quality. Implications for policy and practice are discussed.  相似文献   

Two- to eight-month-old infants' perception of dynamic auditory-visual spatial colocation     

Bremner JG  Slater AM  Johnson SP  Mason UC  Spring J  Bremner ME 《Child development》2011,82(4):1210-1223

From birth, infants detect associations between the locations of static visual objects and sounds they emit, but there is limited evidence regarding their sensitivity to the dynamic equivalent when a sound-emitting object moves. In 4 experiments involving thirty-six 2-month-olds, forty-eight 5-month-olds, and forty-eight 8-month-olds, we investigated infants' ability to process this form of spatial colocation. Whereas there was no evidence of spontaneous sensitivity, all age groups detected a dynamic colocation during habituation and looked longer at test trials in which sound and sight were dislocated. Only 2-month-olds showed clear sensitivity to the dislocation relation, although 8-month-olds did so following additional habituation. These results are discussed relative to the intersensory redundancy hypothesis and work suggesting increasing specificity in processing with age.  相似文献
