This article seeks to put forward one tentative basis on which comparative education might profit from an engagement with 'globalisation', and to circumvent the danger that that engagement will lead to a shift in purpose, from 'how to make education better' to 'how to make education do better'. It uses the example of the career of the New Zealand model of neo-liberalism and new public management to expose, from the perspective of how a 'localism' becomes globalised, something of the nature of the processes, discourses and mechanisms of globalisation and of the subjects who drive them. The article examines the local conditions that enabled the development and installation of the New Zealand model, the discursive and formal characteristics that made it desirable and possible for it to be incorporated at a global level, and the means through which this was done. It concludes by drawing some possible theoretical and methodological implications of the career of the New Zealand model for the relationship between comparative education and globalisation.  相似文献

This study investigates how audience members relate to and vicariously interact with multiple characters while viewing a narrative. Under the framework of the theory of situation models, we applied a real-time thought-listing technique that incorporated Twitter and focused on three debuting TV dramas to explore how the participants followed multiple characters while watching prime-time television dramas. We examined 3,274 tweets across the three TV series and found that monitoring a greater diversity of characters is associated with an increased number of questions asked and more accurate predictions of future events. The participants who made more accurate predictions had higher narrative engagement. In addition, the participants who had more thoughts about the self tracked a greater diversity of characters and made more accurate predictions about the plot. The results are discussed in terms of the developing literature on narratives in mass communication and entertainment research.  相似文献

Abstract

Micro-sensors were used to quantify macro kinematics of classical cross-country skiing techniques and measure cycle rates and cycle lengths during on-snow training. Data were collected from seven national level participants skiing at two submaximal intensities while wearing a micro-sensor unit (MinimaxX?). Algorithms were developed identifying double poling (DP), diagonal striding (DS), kick-double poling (KDP), tucking (Tuck), and turning (Turn). Technique duration (T-time), cycle rates, and cycle counts were compared to video-derived data to assess system accuracy. There was good reliability between micro-sensor and video calculated cycle rates for DP, DS, and KDP, with small mean differences (Mdiff% = ?0.2 ± 3.2, ?1.5 ± 2.2 and ?1.4 ± 6.2) and trivial to small effect sizes (ES = 0.20, 0.30 and 0.13). Very strong correlations were observed for DP, DS, and KDP for T-time (r = 0.87–0.99) and cycle count (r = 0.87–0.99), while mean values were under-reported by the micro-sensor. Incorrect Turn detection was a major factor in technique cycle misclassification. Data presented highlight the potential of automated ski technique classification in cross-country skiing research. With further refinement, this approach will allow many applied questions associated with pacing, fatigue, technique selection and power output during training and competition to be answered.  相似文献

In structural equation models, outliers could result in inaccurate parameter estimates and misleading fit statistics when using traditional methods. To robustly estimate structural equation models, iteratively reweighted least squares (IRLS; Yuan & Bentler, 2000) has been proposed, but not thoroughly examined. We explore the large-sample properties of IRLS and its effect on parameter recovery, model fit, and aberrant data identification. A parametric bootstrap technique is proposed to determine the tuning parameters of IRLS, which results in improved Type I error rates in aberrant data identification, for data sets generated from homogenous populations. Scenarios concerning (a) simulated data, (b) contaminated data, and (c) a real data set are studied. Results indicate good parameter recovery, model fit, and aberrant data identification when noisy observations are drawn from a real data set, but lackluster parameter recovery and identification of aberrant data when the noise is parametrically structured. Practical implications and further research are discussed.  相似文献

Effects of college prestige on men's occupational status and income   总被引:1,自引:1,他引:1  
This study assesses the effects of college social prestige and college selectivity on men's occupational status and income. The analyses are based on a national sample of men from the Panel Study of Income Dynamics. College selectivity, but not college social prestige, has a significant impact on middle-aged men's income in a single year. Neither college social prestige nor selectivity, however, affect further growth in middle-aged men's income. Nor do they affect men's occupational status.  相似文献

Objective

To investigate the stress distribution to the mandible, with and without impacted third molars (IM3s) at various orientations, resulting from a 2000-Newton impact force either from the anterior midline or from the body of the mandible.

Materials and methods

A 3D mandibular virtual model from a healthy dentate patient was created and the mechanical properties of the mandible were categorized to 9 levels based on the Hounsfield unit measured from computed tomography (CT) images. Von Mises stress distributions to the mandibular angle and condylar areas from static impact forces (Load I-front blow and Load II left blow) were evaluated using finite element analysis (FEA). Six groups with IM3 were included: full horizontal bony, full vertical bony, full 450 mesioangular bony, partial horizontal bony, partial vertical, and partial 450 mesioangular bony impaction, and a baseline group with no third molars.

Results

Von Mises stresses in the condyle and angle areas were higher for partially than for fully impacted third molars under both loading conditions, with partial horizontal IM3 showing the highest fracture risk. Stresses were higher on the contralateral than on the ipsilateral side. Under Load II, the angle area had the highest stress for various orientations of IM3s. The condylar region had the highest stress when IM3s were absent.

Conclusions

High-impact forces are more likely to cause condylar rather than angular fracture when IM3s are missing. The risk of mandibular fracture is higher for partially than fully impacted third molars, with the angulation of impaction having little effect on facture risk.

Prompting systems are guidelines of when to provide learners with prompts and when to fade prompts. Today, there are several prompting systems implemented to teach receptive labeling to individuals diagnosed with autism spectrum disorders and other disabilities. This study compared most‐to‐least prompting to an error correction procedure involving feedback and remedial trials for teaching two children with autism a variety of receptive labels. All teaching was implemented in a one‐to‐one instructional setting. Researchers taught each participant how to receptively identify 18 pictures; nine were taught using error correction and nine were taught using most‐to‐least. The researchers utilized an adapted alternating treatment design nested into a multiple probe design to evaluate the two procedures. Results indicated that participants were able to reach mastery criterion on 100% of skills taught using the error correction and were able to reach mastery criterion on 88.9% of skills taught using most‐to‐least. Additionally, error correction tended to require fewer trials for participants to reach mastery criterion.  相似文献

Infants with Down syndrome (DS) represent a population in which new behaviors are acquired significantly more slowly than in nondisabled infants. We propose that infants' spontaneous movements hold a key to understanding the process of development—of integrating intrinsic dynamics and function. In this investigation, we compared the spontaneous leg movements of 10 infants with DS and 2 groups of nondisabled (ND) infants matched for chronological age and motor age. In contrast to common perceptions, we did not observe a significant difference in the frequency of movements between infants with DS and ND infants. But, infants with DS demonstrated significantly fewer of the most complex patterned leg movements, that is, kicking patterns. Further, the frequency with which both DS and ND infants kicked was significantly correlated with the age at which they began to walk. Biomechanical variables were identified, as well, that related to their emergent movement patterns. These data are consistent with Edelman's proposal that spontaneous movements that occur repeatedly in regions of the organism's functional work space facilitate the development of stable behavioral patterns and emphasize the role of the interaction of multiple subsystems in the emergence of new behaviors.  相似文献
