The Role of Critique in Philosophy of Education: its Subject Matter and its Ambiguities     

Frieda Heyting  Christopher Winch 《Journal of Philosophy of Education》2004,38(3):311-321

The role of critique in the Anglophone analytical tradition of philosophy of education is outlined and some of its shortcomings are noted, particularly its apparent claim to methodological objectivity in arriving at what are clearly contestable positions about the normative basis of education. Many of these issues can be seen to have a long history within European, and especially German, philosophy of education. In the light of this the discussion moves on to a consideration of similarities and contrasts between the Anglophone and German‐inspired deployment of the concept of critical rationality in philosophy of education. The claims to objectivity of the Anglophone tradition are contrasted with a more self‐conscious concern for social justice and improvement in other European traditions, which has been followed more recently by a greater scepticism concerning the potential of critique for delivering social justice and improvement in education. This has parallels with the growing Anglophone disillusion with ‘classical’ analytic philosophy of education. This in turn has resulted in a greater awareness of the limitations of critique: its ideological character, its rootedness in specific contexts, its own potential dogmatism and its ambiguities. The various contributions to this volume are briefly described and related to each other.  相似文献

体育赞助效果评估     

Christoph Breuer  Christopher Rumpf  席驰 《北京体育大学学报》2015,38(4):18-25

摘要：据普华永道2012年度报告显示,全球体育赞助投入预计在2013年将达到352亿美元,较之2012年上涨5.1%。较于体育赞助市场的蓬勃发展,体育赞助效果的评估方法仍然处于探索阶段。目前广泛应用的评估方法仅是分析赞助信息曝光度对消费者记忆度的影响。然而,消费者接收和认知赞助信息的过程却被完全忽略。为弥补这一研究领域空白,研究采用实验法,利用视线追踪技术分析消费者对赞助刺激的注意力,通过回归模型分析消费者对赞助刺激的认知处理过程。实验结果表明消费者对赞助刺激的注意力是由赞助刺激的摆放位置和影响曝光度的三种因素所决定的;另外,消费者对赞助商的回忆度取决于消费者注意力和品牌熟悉度等因素。因此,赞助商应当首要考虑赞助刺激对消费者注意力的影响。基于本实验结果建立的体育赞助效果评估模型,可以帮助赞助商评估赞助效果和赞助合约价值。  相似文献   

Thermally multiplexed polymerase chain reaction     

Christopher R. Phaneuf  Nikita Pak  D. Curtis Saunders  Gregory L. Holst  Joav Birjiniuk  Nikita Nagpal  Stephen Culpepper  Emily Popler  Andi L. Shane  Robert Jerris  Craig R. Forest 《Biomicrofluidics》2015,9(4)

Amplification of multiple unique genetic targets using the polymerase chain reaction (PCR) is commonly required in molecular biology laboratories. Such reactions are typically performed either serially or by multiplex PCR. Serial reactions are time consuming, and multiplex PCR, while powerful and widely used, can be prone to amplification bias, PCR drift, and primer-primer interactions. We present a new thermocycling method, termed thermal multiplexing, in which a single heat source is uniformly distributed and selectively modulated for independent temperature control of an array of PCR reactions. Thermal multiplexing allows amplification of multiple targets simultaneously—each reaction segregated and performed at optimal conditions. We demonstrate the method using a microfluidic system consisting of an infrared laser thermocycler, a polymer microchip featuring 1 μl, oil-encapsulated reactions, and closed-loop pulse-width modulation control. Heat transfer modeling is used to characterize thermal performance limitations of the system. We validate the model and perform two reactions simultaneously with widely varying annealing temperatures (48 °C and 68 °C), demonstrating excellent amplification. In addition, to demonstrate microfluidic infrared PCR using clinical specimens, we successfully amplified and detected both influenza A and B from human nasopharyngeal swabs. Thermal multiplexing is scalable and applicable to challenges such as pathogen detection where patients presenting non-specific symptoms need to be efficiently screened across a viral or bacterial panel.  相似文献   

Undisclosed Flexibility in Computing and Reporting Structural Equation Models in Communication Science     

Christopher Scott Seaman  Rene Weber 《Communication methods and measures》2015,9(4):208-232

The use of structural equation modeling (SEM) in communication research has become increasingly popular in recent years, with SEM being commonly used as the primary method of data analysis in studies published within the field’s journals. However, despite its widespread use, there are persistent misapplications of SEM in published empirical studies in the communication sciences. Of these types of misuse, the most troubling are those related to the exploitation of flexibilities in data collection and analysis. Given the number of decisions that must be made when analyzing and reporting structural equation models, decisions which often remain undisclosed, the potential for researchers to exploit flexibilities in SEM research is high. To assess the extent of this problem, as well as the more longstanding types of misuse (i.e., omission of information and disclosed “bad practice”) identified by prior studies, we undertake a methodical review of studies employing structural equation modeling within major journals in the field of communication between the years 2007 and 2011. Articles were coded on the characteristics of the sample, characteristics of the model tested, as well as for various potential problems that we defined a priori. The most serious issues are identified, and recommendations for future standards in SEM research are suggested.  相似文献

¡No lucro! … from protest catch cry to presidential policy: is this the beginning of the end of the Chilean neoliberal model of education?     

Christopher Tome 《Journal of educational administration and history》2015,47(2):193-208

This paper surveys the delivery of school education in Chile over the last half-century. It focuses on evidence provided by recent academic studies on the impact of neoliberal education policies introduced by the military regime in the 1980s, and continued by successive democratic governments. It offers insights into recent popular critiques of the neoliberal model, as reported in the Chilean press, and reflected by significant popular support for student protest movements demanding the end of for-profit schools, and the revitalisation of the public school system – encapsulated in the protesters’ catch cry of ¡No lucro! It considers possible consequences of the adoption, as policy, of that catch cry, by the recently elected Bachelet government.  相似文献   

Children's literacy interest and its relation to parents’ literacy‐promoting practices          下载免费PDF全文

Laura E. Hume  Christopher J. Lonigan  Jessica D. McQueen 《Journal of Research in Reading》2015,38(2):172-193

This study examined how children's literacy interests related to parent literacy‐promoting practices across time. Using a sample of 909 preschool‐age children and the newly developed Child Activities Preference Checklist, literacy interest appeared to be a complex construct, not easily captured by a single measure. In a subsample of 230 children with longitudinal data, parent literacy practices and child literacy interests related concurrently and across time. Parent literacy practices were more stable than child literacy interests, with children's literacy interest continuing to develop over the preschool year. Parent practices of exposing children to literacy and teaching them literacy concepts appeared to be distinct constructs. Exposure to literacy was especially important in the growth of literacy interests and the hypothesis that exposure has a negative effect on children with little initial interest was not fully supported.  相似文献
