CrossRef and the research experience     

Amy Brand 《Learned Publishing》2004,17(3):225-230

CrossRef is an independent membership association for building collaborative publishing technologies. Its mission is to provide services that enable the scholar to reach source material easily; it focuses on methods that are best achieved through collective agreement among publishers. The CrossRef network now covers millions of journal articles and other content items from hundreds of publishers. This article looks at CrossRef's significance for the online research experience, four years after the launch of the CrossRef initiative.  相似文献

Application of Think Aloud Protocols for Examining and Confirming Sources of Differential Item Functioning Identified by Expert Reviews     

Kadriye Ercikan  Rubab Arim  Danielle Law  Jose Domene  France Gagnon  Serge Lacroix 《Educational Measurement》2010,29(2):24-35

This paper demonstrates and discusses the use of think aloud protocols (TAPs) as an approach for examining and confirming sources of differential item functioning (DIF). The TAPs are used to investigate to what extent surface characteristics of the items that are identified by expert reviews as sources of DIF are supported by empirical evidence from examinee thinking processes in the English and French versions of a Canadian national assessment. In this research, the TAPs confirmed sources of DIF identified by expert reviews for 10 out of 20 DIF items. The moderate agreement between TAPs and expert reviews indicates that evidence from expert reviews cannot be considered sufficient in deciding whether DIF items are biased and such judgments need to include evidence from examinee thinking processes.  相似文献   

Establishing the structure of reality for an industry: model and anti-model arguments as advocacy in Nike's crisis communication     

Timothy Sellnow  Jeffrey Brand 《Journal of Applied Communication Research》2001,29(3):278-295

This study illustrates the potential role of model and anti-model arguments in organizational crisis communication. Specifically, model and anti-model arguments are described as a strategy for moving the focus of a crisis from an organization to its industry. Model arguments enable organizations to establish their corrective action as industry standards that merit imitation. Conversely, organizations can set minimum standards for their industries with anti-model arguments. Phil Knight's May 12, 1998, speech announcing Nike's new initiatives in global manufacturing is analyzed as a case study. The essay concludes that model and anti-model arguments can suspend criticism of the organization, create the foundation for a return to industry prominence by the organization, and establish proposed new industry standards that are favorable to the organization.  相似文献   

Home–School Literacy Bags for Twenty-first Century Preschoolers     

Susan Trostle Brand  Jessica Marchand  Elizabeth Lilly  Martha Child 《Early Childhood Education Journal》2014,42(3):163-170

Combining home–school literacy bags with preschool family literature circles provided a strong foundation for family involvement at home and school during this year-long Reading Partners project, and helped parents become essential partners in their children’s literacy development. Using home–school literacy bags, children and parents learned how to combine expressive arts and emergent literacy strategies including alphabet recognition, phonemic and phonological awareness, and oral language fluency. State-of-the-art activities designed for each of the multiple intelligences met the needs of diverse students with many different learning styles and interests. As families participated in fall and spring school-based Festivals in which they shared the literacy bags in small group family literature circles, they demonstrated children’s emerging literacy skills in a relaxed, yet highly engaging atmosphere.  相似文献   

Fear potentiation of the acoustic startle reflex using noises of various spectral frequencies as conditioned stimuli     

Serge Campeau  Michael Davis 《Learning & behavior》1992,20(2):177-186

The effectiveness of noise of various intensities and frequencies in modulating the amplitude of the acoustic startle reflex was evaluated, as a preliminary test of the capacity of these noises to produce consistent and reliable fear-potentiated startle in rats. It was determined that bands of noise containing high frequencies (greater than 10 kHz) tend to unconditionally reduce acoustic startle responses, probably by masking the high-frequency startle-eliciting stimulus. Noise containing high frequencies produced reliable fear-potentiated startle only when its estimated unconditioned startle suppression was subtracted from the enhancement obtained after pairing it with footshocks. Noises devoid of high frequencies produced modest-unconditioned startle enhancements and the most robust and reliable fear-potentiated startle when they were paired with footshocks. A nonmonotonic relationship between training shock intensity and the level of fear-potentiated startle was also exhibited when a low-frequency noise was used as a conditioned stimulus, a finding consistent with previous studies in which a visual stimulus was used. Finally, a differential Pavlovian conditioning procedure indicated that rats could readily discriminate between two different low-frequency bands of noise. The outcome of these experiments indicates that it is easier to employ low-frequency bands of noise to obtain auditory fear-potentiated startle with high-frequency startle-eliciting stimuli.  相似文献

Crossing cultural borders into science teaching: Early life experiences,racial and ethnic identities,and beliefs about diversity     

Brenda R. Brand  George E. Glasson 《科学教学研究杂志》2004,41(2):119-141

The purpose of this ethnographic study was to explore the development of belief systems as related to racial and ethnic identities of preservice teachers as they crossed cultural borders into science teaching. Data were collected throughout a yearlong teacher preparation program to learn how early life experiences and racial and ethnic identities of preservice teachers influenced both their beliefs about diversity in science classrooms and science teaching pedagogy. Case studies of three preservice teachers from diverse racial and ethnic background are presented: Asian American, African American, and Rural Appalachian. Using Bank's ethnicity typology, findings suggest that racial and ethnic identity, developed in early life experiences of preservice teachers, provided clarity on the rigidity of their beliefs about diversity and how they view science teaching. By learning about the border crossing experiences of preservice teachers in relation to their beliefs about diversity as related to racial and ethnic identities, the researchers hoped to provide insight on preparing preservice teachers for the challenges of working in diverse classrooms. © 2004 Wiley Periodicals, Inc.

Capacité cognitive,sentiment d’auto-efficacité et autorégulation     

Thérèse Bouffard-Bouchard  Sophie Parent  Serge Larivée 《European Journal of Psychology of Education - EJPE》1990,5(3):355-364

Feelings of self-efficacy have been the object of several studies that have confirmed its ability to predict performance in different contexts. Yet few studies have been conducted using cognitive or academic tasks in which it is more difficult to clearly distinguish self-efficacy from competence. The present study aims to study the moderating role of cognitive capacity in determining the relationship between self-efficacy and on-line self-regulation observed while solving a verbal concept formation task. In order to distinguish self-efficacy from competence, 44 subjects were selected based on the results of their SSPI; these results of which are related to comprehension ability. Analyses of results allow us to observe that, when compared to subjects who consider themselves less efficacious, subjects who have strong feelings of self-efficacy have a higher success rate, are more certain of these successes and reject fewer correct hypotheses, no matter what their cognitive ability. These results once again bring to light the relative independance of cognitive ability and motivational determinants of a person’s actual accomplishments.  相似文献
