Refinements Introduced in the Oddy Test Methodology

The ‘Oddy test’ is an accelerated corrosion test introduced in the 1970s at the British Museum to identify materials likely to emit volatile substances that could harm museum artefacts. It is carried out in many museums all around the world, but not always using the same methodology, which makes it difficult to compare and share test results between institutions. Refinements to the Oddy test methodology have been implemented at the British Museum over the last decade and the aim of this paper is to present these and promote consistency across institutions. The modifications introduced concern the method used to wash the glassware, the preparation of the metal coupons, and standard methods for preparing samples of liquid coatings, adhesives, and adhesive tapes. Finally, conducting Oddy tests is time consuming and measures employed at the British Museum to reduce the number of materials to be tested and streamline testing are described.     

Pop-Up Library at the University of Birmingham: Extending the Reach of an Academic Library by Taking “The Library” to the Students

ABSTRACT

Aligning with student engagement and promotional strategies, a Pop-Up Library project was initiated at the University of Birmingham. This involved setting up temporary, staffed stalls in different locations across campus in order to informally communicate with students and effectively take “the Library” to them. This article discusses the planning and implementation of the Pop-Up Library, including the rationale for the initiative. Details are given of the stalls themselves, the wide range of staff involved, the many locations trialed, the promotional materials used, and the ways in which the venture was advertised and subsequently evaluated. Results of a questionnaire used on the stalls are presented. Conclusions are drawn as to the effectiveness of the Pop-Up Library as a communication tool, with particular emphasis on breaking down barriers between students and library staff, and proactively raising students' awareness of the many ways Library Services can enhance their learning.     

The genetic and environmental covariation among psychopathic personality traits, and reactive and proactive aggression in childhood

The present study investigated the genetic and environmental covariance between psychopathic personality traits with reactive and proactive aggression in 9- to 10-year-old twins (N = 1,219). Psychopathic personality traits were assessed with the Child Psychopathy Scale (D. R. Lynam, 1997), while aggressive behaviors were assessed using the Reactive Proactive Questionnaire (A. Raine et al., 2006). Significant common genetic influences were found to be shared by psychopathic personality traits and aggressive behaviors using both caregiver (mainly mother) and child self-reports. Significant genetic and nonshared environmental influences specific to psychopathic personality traits and reactive and proactive aggression were also found, suggesting etiological independence among these phenotypes. Additionally, the genetic relation between psychopathic personality traits and aggression was significantly stronger for proactive than reactive aggression when using child self-reports.     

Does generating examples aid proof production?

Many mathematics education researchers have suggested that asking learners to generate examples of mathematical concepts is an effective way of learning about novel concepts. To date, however, this suggestion has limited empirical support. We asked undergraduate students to study a novel concept by either tackling example generation tasks or reading worked solutions to these tasks. Contrary to suggestions in the literature, we found no advantage for the example generation group on subsequent proof production tasks. From a second study, we found that undergraduate students overwhelmingly adopt a trial and error approach to example generation and suggest that different example generation strategies may result in different learning gains. We conclude by arguing that the teaching strategy of example generation is not yet understood well enough to be a viable pedagogical recommendation.     

Benefits of early childhood interventions across the world: (Under) Investing in the very young

This paper reviews the international (non-U.S.) evidence on the benefits of early childhood interventions. A total of 38 contrasts of 30 interventions in 23 countries were analyzed. It focuses on studies applying a quasi-experimental or random assignment. Studies were coded according to: the type of intervention (cash transfer, nutritional, educational or mixed); sample size; study design and duration; country; target group (infants, prekindergarten); subpopulations of interventions; and dosage of intervention. Cohen's D effect sizes were calculated for four outcomes: cognitive gains; behavioral change; health gains; and amount of schooling. We find children from different context and countries receive substantial cognitive, behavioral, health and schooling benefits from early childhood interventions. The benefits are sustained over time. Interventions that have an educational or stimulation component evidenced the largest cognitive effects.     

Classwide consultation in preschools: A case study of comprehensive supports

Classwide supports were used to increase children's early literacy skills for Head Start morning and afternoon classrooms within a preschool Response to Intervention (RtI) model. Support included interventions to improve child outcomes for letter naming fluency (LNF) and teachers' instructional and managerial variables. Targeted activities included circle (a group instructional activity) and center times (also instructional time with children's choices about activities). Support for teachers included adding a “letter of the week” activity with active responding and other literacy activities and providing direct feedback to teachers about classroom managerial interactions. Results show positive classwide improvements for LNF, an increase in the prevalence of instruction, and improvements in positive and instructional managerial methods. Social validity appraisal indicated that the support methods were highly acceptable. © 2010 Wiley Periodicals, Inc.
