Second order change: Impact of a college renewal program over time

A structured faculty professional development program which deliberately seeks to bring about change can yield lasting benefits for both the individual and the institution. Ten individuals who entered a program for the professional renewal of faculty between 1983 and 1987 were interviewed to discover what impact the program had on their professional development and on their contributions to the institution. Their experiences exhibit external and internal changes, with individuals being able to reflect upon their gains, contributions, and future directions. A basic model for support needed to bring about lasting change includes the elements ofpower, vision, structure, andresources.Joyce P.

Interaction of sample dimension and sample-comparison mapping on pigeons’ performance of delayed conditional discriminations

Coding strategies developed in the acquisition of delayed conditional discriminations can be assessed by independently manipulating sample and comparison memory load. Two stimulus dimensions that can affect memory load were examined: Number of stimuli in the sample and comparison sets (two vs. four) was manipulated between groups in a 2×2 design, and discriminability of sample and comparison stimuli (hues vs. lines) was manipulated between counterbalancing subgroups and within subjects. The results indicated large effects of sample discriminability but not of comparison discriminability, evidence for retrospective coding. There was also a significant effect of number of stimuli in the comparison set (although only with hard-to-discriminate samples) but not of number of stimuli in the sample set, evidence for prospective coding. These findings suggest evidence for retrospective coding with easy-to-discriminate samples, independently of number of stimuli in the comparison set, and evidence for prospective coding with hard-to-discriminate samples.

Tracing the Sources

This article explores health journalists’ sourcing patterns in the Dutch-speaking part of Belgium across a range of different media including newspapers, magazines, radio, television and online health news websites. A cross-sectional quantitative content analysis of health news items collected in February 2015 (N?=?981) was established to examine the number and origin (e.g. industry, citizens, experts) of sources (N?=?1998) mentioned in health news stories with particular attention paid to differences across various media types. Despite recent claims of media convergence, cross-media comparisons are scarce and, for a specialized beat such as health, nonexistent. The key findings of this study indicate that ordinary citizens and academic experts constitute the two largest source categories. The small share of industry-related sources confirms journalists’ skeptical attitude towards content provided by the industry. But on closer inspection, large differences can be observed across various media types. On the one hand, ordinary citizens occur with relatively high frequency on television but hardly make an appearance in online news items. Academic sources, on the other hand, are dominant online but nearly absent in television news items. In sum, this analysis demonstrates that health journalists’ source uses differ across various media platforms.     

Assessment of indoor air quality and the risk of damage to cultural heritage objects using MEMORI® dosimetry

Air pollution is one of the environmental influences that degrade cultural heritage objects situated indoors. Other essential influences, such as temperature, relative humidity, and light are often well monitored. The presence of air pollutants is less often measured or included in risk assessment. The MEMORI^® technology presented in this paper was developed as a tool for easy measurement and assessment of the general risk of degradation of heritage objects situated indoors due to indoor exposure to air pollutants. MEMORI dosimetry was performed in locations belonging to English Heritage and Tate (both located in London) and the National Archives of Norway in Oslo, to assess air quality. The related damage risk for collection objects and the protection offered by display and storage designs was assessed. A high level of acidic effect was observed inside a number of showcases, and a high level of oxidizing effect was observed in some room locations. Relatively simple mitigation measures, such as constructing tightly sealed showcases using low emitting materials, installing active carbon absorbing media inside a ‘microclimate’ frame, and using cardboard storage boxes for paper, significantly improved air quality. Overall, implementation of such measures is likely to improve the preservation of objects and reduce conservation costs.
