In Canada, current federal learning-and-work policy is focused on individual learner-worker development using an iteration of lifelong learning as cyclical. This policy aims to enhance the social as an effect of enhancing the economic. In this neoliberal milieu, cyclical lifelong learning has become not only a norm but also a culture and an attitude. Still, a current Canadian phenomenon indicates that increasing numbers of young adults are disengaging from participation in such learning that the federal government considers being a preventive measure. In discussing their withdrawal from what might be perceived as cyclical lifelong learning for control, I consider a particularly challenging case: the predicament of young adults in the Canadian province of Newfoundland and Labrador. To help us think about adequately addressing the dislocation they experience in life and work, I offer a Freire-informed vision of a critical social pedagogy of learning and work. This pedagogy calls for re-engendering the social in lifelong learning by revitalizing critical social concerns with historical awareness, hope, possibility, ethics, justice, democratic vision, learner freedom, critique, and intervention. 相似文献

This article reflects on the desire to defend and claim public education amidst the educational policy effects of contemporary neoliberal politics. The defence of public education, from schools to higher education, undoubtedly provides a powerful counter-veiling weight to the neoliberal policy logic of education-as-individual-value-accrual. At a time of intense global policy reform centred on marketisation in education, the public education institutions of the post-war welfare state are often characterised as being lost, attacked, encroached upon and dismantled. In this paper, I contend it is important to avoid mobilising a memory of public educational pasts that do not account for their failings and inequalities. Turning to a historical engagement with the emergence of neoliberal politics, the paper explores how challenges and contestations surrounding ‘the public’ from multiple standpoints converged in the rise of neoliberalism. Recognition of these convergences and contestations, I suggest, assists to provide a more nuanced account of the relationship between neoliberal reform and the welfare state, and thus of the complex task of imagining, claiming and working towards a just and equitable public education. 相似文献

The recent migration of 65,000 children across the southwestern border, coupled with allegations of abuse by the U.S. Border Patrol, enables the investigation of an overlooked immigrant category: the unaccompanied youth migrant. Analyzing audience responses to news reports of the abuse, we find that established disparaging immigrant tropes apply, describing the children as an economic burden, disease carriers, and offspring of irresponsible families. We uncover two new themes: Youth migrants are channels whereby criminals may infiltrate the U.S., and manipulate legal authorities to remain in the U.S. Finally, we demonstrate how global compassion is strategically deployed to qualify harsh retaliatory measures. 相似文献

Paralympic throwing events for athletes with physical impairments comprise seated and standing javelin, shot put, discus and seated club throwing. Identification of talented throwers would enable prediction of future success and promote participation; however, a valid and reliable talent identification battery for Paralympic throwing has not been reported. This study evaluates the reliability and validity of a talent identification battery for Paralympic throws. Participants were non-disabled so that impairment would not confound analyses, and results would provide an indication of normative performance. Twenty-eight non-disabled participants (13 M; 15 F) aged 23.6 years (±5.44) performed five kinematically distinct criterion throws (three seated, two standing) and nine talent identification tests (three anthropometric, six motor); 23 were tested a second time to evaluate test–retest reliability. Talent identification test–retest reliability was evaluated using Intra-class Correlation Coefficient (ICC) and Bland–Altman plots (Limits of Agreement). Spearman’s correlation assessed strength of association between criterion throws and talent identification tests. Reliability was generally acceptable (mean ICC = 0.89), but two seated talent identification tests require more extensive familiarisation. Correlation strength (mean rs = 0.76) indicated that the talent identification tests can be used to validly identify individuals with competitively advantageous attributes for each of the five kinematically distinct throwing activities. Results facilitate further research in this understudied area. 相似文献

Shear stress is the major mechanical force applied on vascular endothelial cells by blood flow, and is a crucial factor in normal vascular physiology and in the development of some vascular pathologies. The exact mechanisms of cellular mechano-transduction in mammalian cells and tissues have not yet been elucidated, but it is known that mechanically sensitive receptors and ion channels play a crucial role. This paper describes the use of a novel and efficient microfluidic device to study mechanically-sensitive receptors and ion channels in vitro, which has three independent channels from which recordings can be made and has a small surface area such that fewer cells are required than for conventional flow chambers. The contoured channels of the device enabled examination of a range of shear stresses in one field of view, which is not possible with parallel plate flow chambers and other previously used devices, where one level of flow-induced shear stress is produced per fixed flow-rate. We exposed bovine aortic endothelial cells to different levels of shear stress, and measured the resulting change in intracellular calcium levels ([Ca2+]i) using the fluorescent calcium sensitive dye Fluo-4AM. Shear stress caused an elevation of [Ca2+]i that was proportional to the level of shear experienced. The response was temperature dependant such that at lower temperatures more shear stress was required to elicit a given level of calcium signal and the magnitude of influx was reduced. We demonstrated that shear stress-induced elevations in [Ca2+]i are largely due to calcium influx through the transient receptor potential vanilloid type 4 ion channel. 相似文献

Testing a component model of reading comprehension in a randomized controlled trial, we evaluated the efficacy of 4 interventions that were designed to target components of language and metacognition that predict children’s reading comprehension: vocabulary, listening comprehension, comprehension of literate language, academic knowledge, and comprehension monitoring. Third- and 4th-graders with language skills falling below age expectations participated (N = 645). Overall, the component interventions were only somewhat effective in improving the targeted skills, compared to a business-as-usual control (g ranged from ?.14 to .33), and no main effects were significant after correcting for multiple comparisons. Effects did not generalize to other language skills or to students’ reading comprehension. Moreover, there were Child Characteristic × Treatment interaction effects. For example, the intervention designed to build sensorimotor mental representations was more effective for children with weaker vocabulary skills. Implications for component models of reading and interventions for children at risk of reading comprehension difficulties are discussed. 相似文献
