White lies: a racial history of the (post)truth     

Robert Mejia  Kay Beckermann  Curtis Sullivan 《传播与批判/文化研究》2018,15(2):109-126

In the aftermath of the 2016 election of President Trump, a veritable cottage industry of opinion pieces, blogs, and articles emerged overnight, most of which seemed to agree that only the post-truth could explain how a racist, misogynistic, neo-nationalist member of the economic elite could win a presidential election. This article, in contrast, is inspired by Barbara Christian’s injunction that we question why a given statement, concept, or theory is now acceptable when before it was not. Operating in this spirit, we critique post-truth critics for neglecting the material tradition of ideological criticism in favor of epistemological explanations for understanding post-truth literature; we then offer two case studies—American drug policy and housing policy—to illustrate the racial amnesia required for claiming that only now do we live in a post-truth era.  相似文献   

Finding the common ground: Teachers' and employers' representations of English in an assessment context          下载免费PDF全文

Simon Child  Martin Johnson  Sanjana Mehta  Annabel Charles 《English in Education》2015,49(2):150-166

There has been a long‐standing debate about how ‘English’ can be defined. Educational policy changes have typically been driven by differing representations of the subject, and have ranged from broad ‘aesthetic’ definitions to more narrow ‘functional’ views. The present study aims to analyse areas of consensus and contention in stakeholders' discourse regarding English. A questionnaire‐based survey and focus groups were used to explore how teachers and employers viewed English as a subject. Their views were conceptualised into three themes: the importance of functional English; English as atomistic versus holistic study; and English as critical thought. These themes are discussed in relation to historical definitions of ‘English’, and their implications for the future reform of English qualifications.  相似文献   

Recreational angling tournaments: participants' expenditures     

John Curtis  Stephen Hynes  Paul O'Reilly  Benjamin Breen 《Journal of Sport Tourism》2017,21(3):201-221

Fishing tournaments are a common feature in recreational angling across a wide range of target species in both fresh and salt waters. Tournaments are organised for a number of purposes, including as commercial enterprises; as fund-raising initiatives for angling clubs; for economic development purposes (e.g. tourism); as well as improve participants' skill levels. Most tournaments are confined to geographically small areas and usually occur over a small number of days, which can mean a pulse of economically significant activity in the local area. This paper analyses the nature of expenditure associated with angling tournaments, including travel, food and accommodation, and angling-related expenditures as a function of socio-economic and angler characteristics. Analysis based on 106 tournaments across Ireland during 2013 finds a clear 80/20 segmentation between ‘high’- and ‘low’-spend anglers and that the segmentation occurs across all fish target species considered. The analysis also finds that British coarse anglers participating at Irish angling tournaments spend considerably more than other anglers irrespective of target species or angler country of origin.  相似文献   

Age of Entry to Kindergarten and Children's Academic Achievement and Socioemotional Development     

NICHD Early Child Care Research Network 《Early education and development》2007,18(2):337-368

Research Findings: Data on more than 900 children participating in the National Institute of Child Health and Human Development Study of Early Child Care were analyzed to examine the effect of age of entry to kindergarten on children's functioning in early elementary school. Children's academic achievement and socioemotional development were measured repeatedly from the age of 54 months through 3rd grade. With family background factors and experience in child care in the first 54 months of life controlled, hierarchical linear modeling (growth curve) analysis revealed that children who entered kindergarten at younger ages had higher (estimated) scores in kindergarten on the Woodcock—Johnson (W-J) Letter-Word Recognition subtest but received lower ratings from kindergarten teachers on Language and Literacy and Mathematical Thinking scales. Furthermore, children who entered kindergarten at older ages evinced greater increases over time on 4 W-J subtests (i.e., Letter-Word Recognition, Applied Problems, Memory for Sentences, Picture Vocabulary) and outperformed children who started kindergarten at younger ages on 2 W-J subtests in 3rd grade (i.e., Applied Problems, Picture Vocabulary). Age of entry proved unrelated to socioemotional functioning.

Practice: The fact that age-of-entry effects were small in magnitude and dwarfed by other aspects of children's family and child care experiences suggests that age at starting school should not be regarded as a major determinant of children's school achievement, but that it may merit consideration in context with other probably more important factors (e.g., child's behavior and abilities).  相似文献   

Issues in Adopting a Laserdisk-Based Science Curriculum     

David A. Child  Thomas M. Duffy  Sonny Kirkley  Lori Hubbard 《Journal of Science Education and Technology》1997,6(3):161-171

We examined the implementation of a laser-disk based science curriculum in an elementary school. The goal was to develop a richer understanding of the principles for designing a curriculum that will adequately support teachers in adopting a learner-centered framework. Issues included: who has ownership of the classroom discussion; what types of activities are engaged in terms of the constraints imposed; and what is the teacher's response to the specific tools provided (the teacher's guide, the Circle of Learning, and concept maps). In addition to looking at the implementation pattern, we also examined the impact of the implementation on student attitudes and anxiety toward science. Results indicated little adoption of the curriculum, and teachers continued to maintain a high degree of control in the classroom. However, results also indicated significant effects of the curriculum on science attitude and anxiety. Suggestions for future research are included.  相似文献   

Computerized prompting partners and keystroke recording devices: Two macro driven writing tools     

Thomas H. Reynolds  Curtis Jay Bonk 《Educational technology research and development : ETR & D》1996,44(3):83-97

Recent research into composing processes has focused on instructional intervention strategies that promote effective composition practices within computerized writing environments. The field of computers and composition has benefitted both from advances in computing tools and developments in learning theory. The innovative computer tool discussed in this paper uses the macro-command language of a full-featured word processor to enact strategic support designed to help writers with their written work. From a theoretical standpoint, this tool created a writing environment based on Vygotskian theory of mediated learning and was grounded in an instructional strategy known as “procedural facilitation.” To evaluate the effectiveness of this computerprompting tool, a second macro application was used to log student keystrokes, thereby tracking student writing development, revisionary practices, and keystroke reactions to the prompting partner. Students using the prompting tool enacted divergent and convergent thinking assistance that appeared at the bottom of their computer screens while the system saved a process record of their keystrokes. Procedures for creating macro-driven prompting programs and keystroke-logging devices are discussed. Additionally, a catalog of prompts and summary of keystroke-mapping benefits are provided. Finally, our research using the macro-driven prompting partner and keystroke-register tool is detailed.  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
