Choosing and Reading Online News: How Available Choice Affects Cognitive Processing

A within-subjects experiment explored how the number of online, hyperlinked stories available for individuals to choose from affects cognitive processing of a selected story. Participants chose and read unpleasant online news stories from a Web page containing either 5 or 15 headline/photo hyperlinks. Heart rate data indicated more cognitive resources were allocated to reading stories selected from the larger array of hyperlinks. This increased allocation of cognitive resources also led to more accurate story recognition. Results of this study provide insight into information processing of interactive, online news as well as limited suggestions for the design of news Web sites.

The Spiral of Violence: Equity of Violent Reprisal in Professional Wrestling and its Dispositional and Motivational Features

Though lacking empirical evidence, professional wrestling has been criticized for portraying excessive violence in harmful contexts. This study focused on the equity of violent reprisal perpetrated by liked versus disliked protagonists with socially sanctioned or unsanctioned motives. Results of a quantitative content analysis show that most violent interaction sequences were over-retributive. Violence that was not part of match competition was routinely initiated for normatively unsanctioned motives and showed predominant patterns of escalating violent retribution. These patterns held across perpetrator disposition. Thus, liked characters regularly aggressed for normatively unacceptable reasons. The consequences of these portrayals are discussed.

A Brief History of the OCLC Members Council

ABSTRACT

On May 19, 2009, the Online Computer Library Center (OCLC) Members Council held its 90th and final meeting. It was the end of an era that began in 1977, when the Ohio College Library Center changed its name to OCLC and adopted a new governance structure that extended membership in the cooperative to libraries outside Ohio. In the ensuing 30 years, libraries around the world elected 450 delegates to attend three Council meetings each year at OCLC.     

Use of Polarised Light Microscopy to Improve Conservation of Parchment

ABSTRACT

The preservation state of parchment primarily depends on the structure of the collagen fibre network, which in turn is responsible for optical anisotropy, i.e. birefringence. Polarised light microscopy can therefore be used as a non-invasive technique that allows recording of birefringence distribution in the parchment, which directly relates to stress–strain distribution. Using samples from diverse sources (commercial parchment, parchment used by restorers for book binding, and parchment fabricated for the purpose of this study), we assessed the capability of polarised light microscopy for various diagnostics. We performed, for instance, identification of gelatinised regions, layered or ?brous regions in parchment cross section, qualitative analysis of parchment fat content (lipids), observation of stress-induced patterns resulting from tensile tests, and observation of water diffusion. These proof-of-principle experiments extend the capability of polarised light microscopy far beyond its common use and open the path to its deployment in conservation studies.     

Engaging the Experts in Museum Computing: Seven Years of Queries on MCN‐L

MCN‐L, an email listserv administered by the Museum Computer Network, is open to anyone interested in discussing information technology in museums and other cultural heritage organizations. To determine how MCN‐L meets the needs of museum information professionals, this study presents an analysis of more than 6,000 emails sent to the listserv over a seven‐year period (2004–2011). The results of this analysis indicate that MCN‐L adds value to the online community of museum information professionals by providing an online communication channel focused on professional outreach and expert support, backed up by specific examples drawn from personal experiences. MCN‐L's emphasis on personal expertise is a key characteristic that speaks to the listserv's lasting value to the museum community and has implications for researchers and practitioners as they consider the future of computer‐mediated communication for all museum professionals.     

Multiple dimensions of family engagement in early childhood education: Evidence for a short form of the Family Involvement Questionnaire

The primary aim of this study was to develop and validate a short form of the 42-item Family Involvement Questionnaire (FIQ) for use in preschool. Empirical evidence derived from a representative sample of preschool programs in a large city in New York State with the original version of the FIQ was used to select the items for a 21-item short form. A representative sample of 590 Head Start families was also identified from a large Head Start program in Pennsylvania to serve to validate the short form. Confirmatory factor analysis of the short form substantiated the three robust dimensions of family involvement from the original FIQ. Concurrent measures of parental satisfaction and assessments of children's literacy and mathematics skills along with an examination of family demographic variables supported the validity of the confirmed dimensions. Implications for the use of this multidimensional, short form of family involvement in large-scale program evaluation were discussed.     

Mathematical thinking intervention programmes for preschool children with normal and low number sense

This study investigated the possibility of enhancing the level of preschoolers’ number sense by introducing two intervention programmes, Let’s think! and Young children with special educational needs count, too! .Forty‐five preschoolers, mean age 66.4 months, were randomly assigned to the experimental and control groups. The experimental group received instruction twice a week, for half an hour, and for a period of nine months. Pretest–postest comparison revealed that the experimental group showed enhanced number‐sense performance immediately after the instruction ended, but the between‐group difference faded after six months. There were no statistically significant differences between the groups in general mathematical thinking abilities (transfer tasks) after the intervention.
