Light-induced cracking and abrasion of inkjet prints: Damage and mitigation

This study is part of a larger research project at the Image Permanence Institute dedicated to digital print preservation issues – the Digital Print Preservation Portal (DP3). Previous DP3 studies determined that certain digital print types are prone to cracking and/or abrasion, and that factors such as low relative humidity, pollutants, and light increase the brittleness of the ink-receiving layer of some inkjet papers. The purpose of this investigation was to explore if light also increases the propensity of inkjet prints to abrade, and to examine the potential of framing glazings to mitigate light-induced physical damage (cracking and abrasion) by attenuating some portion of the UV spectrum. Inkjet papers and prints were subjected to xenon lighting (to simulate daylight through window glass) without glazing, or in sealed framing packages with plain framing glass (soda-lime) or UV filtering glass. Before and after light exposure, brittleness, and abrasion resistance were evaluated independently using two tests: ISO 18907 (Imaging materials – Photographic films and papers – Wedge test for brittleness) and a rub test utilizing a Sutherland® Rub Tester. In this study, exposure to light increased the cracking and/or abrasion tendency of some specimens. The use of UV filtering glass reduced this light-induced propensity in all cases. Plain glass protected all samples from at least one of these two types of surface damage, but was less effective than UV glass. Light-induced brittleness and sensitivity to abrasion were mostly, though not exclusively, caused by UV radiation. It was also seen that some prints may become brittle and/or prone to abrasion in the absence of image fade. Budgeting the amount of light these objects can be exposed to, protecting them from UV radiation, and handling prints with caution especially after exhibition, is essential in order to limit physical damage.     

Cognitive Representations of Self, Family, and Peers in School-Age Children: Links with Social Competence and Sociometric Status

Attachment and social-cognitive theories of interpersonal relations have underscored the integral role that internalized cognitive representations may play as mediators of the link between family and peer relationships. 3 predictions consistent with this conceptualization received support in the present study of 161 7–12-year-old school children. In Part 1 of the study, significant connections were found among different components of cognitive representations, including social perceptions, interpersonal expectancies, and schematic organization and processing of social information. Moreover, generalization was found among children's representations across 3 interpersonal domains–that is, family, peer, and self. In Part 2, negative representations of self and others were found to be associated with increased social impairment, including dysfunctional social behavior and less positive status in the peer group. Implications of the findings for theories of interpersonal competence and interventions with socially impaired children are discussed.     

Audio‐conferencing in graduate education: A case study

Abstract

This paper reports the findings of a study that examined the relationship between distance teaching and the faculty reward system. Using a qualitative approach, the study sought to understand how distance teaching is valued, rewarded, and accommodated within the institutional reward structure. Based on interviews with faculty members, distance education program administrators, and the chief academic officers at four research universities, the study describes a reward culture that is not accommodating to and rewarding of faculty work in distance education. The study finds that: 1) distance education occupies a marginal status, 2) distance teaching is neither highly valued nor well‐rewarded as scholarly activity, 3) distance teaching is not highly related to promotion and tenure decisions, and 4) rewards for distance teaching are dependent on the academic unit's commitment to distance education.     

‘Crafting the future’: pioneer lessons and concerns for today

A recent qualitative research study gathered the career reflections of the generation of distance education practitioners who developed more flexible higher education (via distance modes) in the second half of the twentieth century. Part of that study’s results focus on the lessons the practitioners learned about what constitutes effective distance education and the concerns they expressed about the future. These are reported here. The key lessons are grouped around patience, tolerance and listening, respectfulness, responsiveness, the qualities needed for innovation and institutional management, and use of technologies. Appropriate use, technical reliability, and critical mindsets emerged as key lessons for technology applications. Ten questions then help readers engage their own reflective thinking and investigate knowledge transfer possibilities.     

Beyond the first year: Supporting sophomores through information literacy outreach

The sophomore year is increasingly becoming a target of retention efforts, as universities and colleges realize that nearly as much attrition occurs between the sophomore and junior years as between the first and sophomore years. As a result, there is an opportunity for libraries to reach out to and target second-year students. This article presents a case study of a sophomore outreach program at the University of Puget Sound focused on citation management software. Our results suggest that libraries should pursue outreach targeting the sophomore population.     

‘ … But we are academics!’ a reflection on using arts-based research activities with university colleagues

Arts-based practices, although familiar in some areas of educational research have the capacity to surprise and to shock: they hold promise but also pose risks. In this essay we introduce arts-based research practices and in particular cut-up and collage. We invite readers to reflect on our experiences of arts-based educational research activities with a group of academic colleagues. We describe what we did, what went wrong, what went right and what we learned.     

Mitigation of light-induced damage on modern digital prints: Photographs and documents

This study is part of a larger research project dedicated to digital print preservation issues – the Digital Print Preservation Portal (DP3). This work quantifies the potential of glazing materials to mitigate different types of light-induced damage – colorant fade, paper yellowing, changes in paper gloss, and loss of optical brightening agent (OBA) function – that occur to digitally printed photographs and documents when on display. Prints were subjected to xenon lighting to simulate daylight through window glass in a series of arrangements: without glazing, with plain framing glass (soda-lime) in a sealed or unsealed package, and with UV blocking glass in a sealed or unsealed package. Sealed packages served the purpose of isolating the samples from atmospheric pollutants, known to contribute to the deterioration of certain print types. In this study, the use of UV-filtering glass protected prints from colorant fade, paper yellowing, and paper gloss change to an extent. Protection conveyed by plain glass was less comprehensive and less effective than UV glass. Neither type of glazing was able to keep the OBAs functional by the end of the light exposure. It was also seen that light-induced damage to digital prints is due not only to UV radiation, but also to visible light, and that different digital prints may be more vulnerable to one or the other. Protecting sensitive prints from UV radiation and budgeting the amount of light they may be exposed to should be essential to any print display policy in order to ensure longevity.
