Serials Data in the Data Age: Project CERES Data for Digitization and Print Preservation     

Amy Wood 《期刊图书馆员》2016,70(1-4):158-167

The report summarizes a presentation given at the 2015 NASIG conference. It outlines metadata used by Project CERES, a print preservation and digitization project supported by a partnership between the United States Agriculture Information Network and the Center for Research Libraries. It also outlines metadata guidelines used to disclose print holdings committed for preservation and provides tips on creating efficiencies in gathering the detailed issue level data and providing quality assurance for digitization. Gathering detailed metadata to support the preservation of print is an investment in the preservation of essential scholarly resources. Project CERES can be used as a model for other programs coupling preservation and digitization.  相似文献   

Naming speed in dyslexia and dyscalculia     

Edith Willburger  Barbara Fussenegger  Kristina Moll  Guilherme Wood  Karin Landerl 《Learning and individual differences》2008,18(2):224-236

In four carefully selected samples of 8- to 10-year old children with dyslexia (but age adequate arithmetic skills), dyscalculia (but age adequate reading skills), dyslexia/dyscalculia and controls a domain-general deficit in rapid automatized naming (RAN) was found for both dyslexia groups. Dyscalculic children exhibited a domain-specific deficit in rapid naming of quantities. This finding is in line with recent assumptions that dyscalculia is associated with a neurobiological deficit in the processing of numerosities. In the dyslexia/dyscalculia group, RAN deficits were additive, that is, the dyslexia/dyscalculia group exhibited the sum of the deficits found in the dyslexia only and dyscalculia only groups. This finding suggests that the cognitive bases of dyslexia and dyscalculia are independent from each other. Within the naming speed paradigm no differential impact of special demands on the executive functions inhibition and shifting was found for any of the four groups.  相似文献   

Reputation Enhancement and Involvement in Delinquency Among High School Students     

Annemaree Carroll  Shauna Green  Stephen Houghton  Robert Wood 《International Journal of Disability, Development & Education》2003,50(3):253-273

The present research explored the relationship between high school students' self-reported delinquency and the importance of their social reputations. The prevalence of self-reported delinquency was investigated in a sample of 965 (467 males, 498 females) Years 8 to 12 students attending high schools in Brisbane and Perth, Australia. The results revealed that males are significantly more prone to all forms of delinquent behaviour than their female peers. Most forms of delinquency appeared to peak at Year 9, with the exception of drug use which increased with age. A cluster analysis was performed on the prevalence data and students were separated into two groups: students with high and low involvement in delinquency. The reputations of students with high and low delinquency involvement were investigated. Students identified as having low involvement in delinquency desired a more conforming reputation than those with high involvement. Females also desired a more conforming reputation than their male counterparts. In relation to year level, junior high school students were less conforming than senior high school students. Ways to address the powerful nature of adolescent reputations and the link between reputational status and involvement in delinquent activities are highlighted.  相似文献

Group interactions in science practical work     

Clare Christensen  DR. Cam McRobbie 《Research in Science Education》1994,24(1):51-59

This study explored the interactions of a highly motivated group of students doing traditional practical work in science. Interest focussed on the social construction of understanding and how this could be described. Despite considerable collaboration in constructing an understanding of the task the students rarely focussed on the concepts the practical work was intended to illustrate. Collaboration was described in terms of social behaviours and discourse moves which supported the use of cognitive strategies. Specializations: science practical work, collaborative group work, role of language. Specializations: science teacher education, conceptual change, learning environments, science reasoning.  相似文献

A New Statistic for Detection of Aberrant Answer Changes          下载免费PDF全文

Sandip Sinharay  Minh Q. Duong  Scott W. Wood 《Journal of Educational Measurement》2017,54(2):200-217

As noted by Fremer and Olson, analysis of answer changes is often used to investigate testing irregularities because the analysis is readily performed and has proven its value in practice. Researchers such as Belov, Sinharay and Johnson, van der Linden and Jeon, van der Linden and Lewis, and Wollack, Cohen, and Eckerly have suggested several statistics for detection of aberrant answer changes. This article suggests a new statistic that is based on the likelihood ratio test. An advantage of the new statistic is that it follows the standard normal distribution under the null hypothesis of no aberrant answer changes. It is demonstrated in a detailed simulation study that the Type I error rate of the new statistic is very close to the nominal level and the power of the new statistic is satisfactory in comparison to those of several existing statistics for detecting aberrant answer changes. The new statistic and several existing statistics were shown to provide useful information for a real data set. Given the increasing interest in analysis of answer changes, the new statistic promises to be useful to measurement practitioners.  相似文献   

Thyroid hormone levels and psychological symptoms in sexually abused adolescent girls     

Haviland MG  Sonne JL  Anderson DL  Nelson JC  Sheridan-Matney C  Nichols JG  Carlton EI  Murdoch WG 《Child abuse & neglect》2006,30(6):589-598

OBJECTIVE: To explore the relationships between psychological symptoms and thyroid hormone levels in adolescent girls who had experienced the traumatic stress of sexual abuse. METHOD: The study design was cross-sectional/correlational. Subjects (N=22; age range=12-18 years) had their blood drawn, and they completed 2 psychological tests (depression and general distress/posttraumatic stress disorder [PTSD]). A pediatrician completed a sexual abuse questionnaire after reviewing law enforcement and Child Protective Services reports and conducting forensic interviews and medical examinations. RESULTS: Girls' average free T4, total T4, free T3, total T3, and TSH levels were within age-specific laboratory reference range limits, as were most individual concentrations. The strongest correlations (p<.05) were between free T3 and PTSD total score (-.50), PTSD-avoidance/numbing (-.49), and general distress (-.48); and between total T3 and depression (-.46), general distress (-.45), and PTSD-arousal (-.44). CONCLUSIONS: Our findings support one of the two contemporary models of the relationships between thyroid hormones (i.e., free and total T3) and psychological symptoms (i.e., depression, general distress, and PTSD)--one of "shutting down" (vs. "activation") in the face of trauma.  相似文献   

Consultation: A team approach to keeping it alive     

Roger Christie  Clare Hetherington  Jenny Parkes 《Educational Psychology in Practice》2000,16(1):39-46

This article sets out to describe how we have kept the model of consultation alive, and what is still, for us, an evolving process and learning experience. We are not planning here to detail the initial development of the model, but to explore the processes and concepts that we continue to use to ensure a genuine team approach is adopted.  相似文献
