In this paper, we draw upon the experiences of a group of young people who have been excluded from mainstream schools in two Australian states to provide an account of the ways in which they have found their way to education in educational sites that are variously referred to as ‘flexible learning centres', ‘second chance schools' and ‘alternative schools'. Whilst often clashing with school authorities in their original schools, these young people described how, when given the opportunity, they were able to engage in more meaningful learning in environments that recognised and accommodated their personal circumstances, and avoided authoritarian rule. A question we address is: What kinds of educational experiences facilitate ‘meaningful learning’ for these students?  相似文献

Second screening is widespread worldwide, particularly in younger populations. We analyze a survey of college students in Brazil and the United States to compare second screening frequency, types, platforms, and motivations between the two countries. Despite lower Internet penetration, Brazilians second screen significantly more than Americans, a result of the country’s tradition of interacting with producers of television. In both countries, those who use the interactive affordances of social media are more likely to second screen. As such, we posit this unique audience-driven act works to bridge Web-connected devices and television to create a converged atmosphere.  相似文献

Strength, technique, and coordination are crucial to rowing performance, but external interventions such as foot-stretcher set-up can fine-tune technique and optimise power output. For the same resultant force, raising the height of foot-stretchers on a rowing ergometer theoretically alters the orientation of the resultant force vector in favour of the horizontal component. This study modified foot-stretcher heights and examined their instantaneous effect on foot forces and rowing technique. Ten male participants rowed at four foot-stretcher heights on an ergometer that measured handle force, stroke length, and vertical and horizontal foot forces. Rowers were instrumented with motion sensors to measure ankle, knee, hip, and lumbar–pelvic kinematics. Key resultant effects of increased foot-stretcher heights included progressive reductions in horizontal foot force, stroke length, and pelvis range of motion. Raising foot-stretcher height did not increase the horizontal component of foot force as previously speculated. The reduced ability to anteriorly rotate the pelvis at the front of the stroke may be a key obstacle in gaining benefits from raised foot-stretcher heights. This study shows that small changes in athlete set-up can influence ergometer rowing technique, and rowers must individually fine-tune their foot-stretcher height to optimise power transfer through the rowing stroke on an ergometer.  相似文献

The Computing Sciences Accreditation Board has accredited 65 programs since 1985. This accreditation has helped to define the field and the computer science profession. The information systems discipline is following much of the historical pattern of computer science. A review of recent efforts to establish accreditation standards for information systems is presented and a draft set of criteria are discussed. Alternative forms of accreditation, institutional vs. programmatic, are presented and discussed in the context of the history of computer science accreditation efforts. This effort is intended to stimulate discussion within the information systems community.  相似文献

The rowing stroke is a leg-driven action, in which forces developed by the lower limbs provide a large proportion of power delivered to the oars. In terms of both performance and injury, it is important to initiate each stroke with powerful and symmetrical loading of the foot stretchers. The aims of this study were to assess the reliability of foot force measured by footplates developed for the Concept2 indoor ergometer and to examine the magnitude and symmetry of bilateral foot forces in different groups of rowers. Five heavyweight female scullers, six heavyweight female sweep rowers, and six lightweight male (LWM) rowers performed an incremental step test on the Concept2 ergometer. Vertical, horizontal, and resultant forces were recorded bilaterally, and asymmetries were quantified using the absolute symmetry index. Foot force was measured with high consistency (coefficient of multiple determination>0.976 ± 0.010). Relative resultant, vertical, and horizontal forces were largest in LWM rowers, whilst average foot forces significantly increased across stroke rates for all three groups of rowers. Asymmetries ranged from 5.3% for average resultant force to 28.9% for timing of peak vertical force. Asymmetries were not sensitive to stroke rate or rowing group, however, large inter-subject variability in asymmetries was evident.  相似文献

As second screening becomes more widespread, this study addresses its mediating role on the impact of TV news in political participation online and offline, and how this impact varies across groups. We expand the existing line of research by assessing the moderating role of support for Donald Trump on the established mediated model. Through a cross-lagged autoregressive panel survey design applied to the communication mediation model, our results support the link between second screening and political participation—but the mediating role of second screening is contingent upon attitudes towards Trump. For those who do not view Trump favorably, second screening during news leads to a decrease in political participation, both online and offline. As such, this article adds to the communication mediation model by suggesting that discussion and elaboration may not always be positive antecedents to political participation. When individuals disagree with the message dominating TV news and social media, deliberation via second screening leads to political disengagement.  相似文献
