Monitoring and Mitigating Particulate Matter Deposition on Decorative Surfaces: Current and Future Approaches in the Palace of Westminster

ABSTRACT

Research into dust deposition rates on the wall paintings in the State Apartments at the Palace of Westminster, London, UK, began during the restoration of the encaustic floor tiles. The study has broadened to inform day-to-day preventive care for the extensive fine art collections on display and the intricately decorated Gothic interiors, providing a powerful tool for the forthcoming restoration and renewal of the Palace. Different monitoring methods, using optical microscopy, macro-photography and software-based image analysis, were investigated. Qualitative analysis with SEM-EDX and optical microscopy allowed the identification of a number of anthropogenic, geogenic and biological sources of particulate matter, while quantitative results elucidated deposition trends, highlighting both seasonal and works-related impacts. Results indicated that mitigation measures taken to protect works of art and limit the diffusion and deposition of particulate matter on surrounding surfaces were successful. A new dust monitoring method, based on imaging of vertical surfaces and on a recently developed image analysis workflow (CHIJ) operated in open-source software (ImageJ) was trialled alongside more traditional methods for measuring dust deposition through collection of particulate matter on proxies. Results showed significant discrepancies between data acquired directly on wall painting surfaces as compared to horizontal glass slides. The advantages, limitations and complementarity of both monitoring methods were identified, and their potential contributions to the development of data-driven conservation approaches for heritage sites were assessed. The relatively low-tech methods and equipment used present useful and adapted tools for collection managers and conservators to inform their decision-making processes.     

Occupational sex segregation and job satisfaction of women

The results of this study indicate wide variation in the effect of occupational sex segregation on the job satisfaction of women college graduates employed in public and private organizations. Women employed in sex-balanced and male- and female-dominated occupations in the public sector have comparable levels of job satisfaction. In private firms, however, women college graduates employed in sex-balanced careers are more satisfied with theintrinsic andoverall nature of their jobs than those employed in female-dominated occupations, and those in female-dominated jobs are more satisfied with theextrinsic nature of their careers than women in male-dominated jobs. The implications of these findings for those who conduct research on the career consequences of women employed in sex-dominated career fields and for college officials responsible for the educational and professional development of women college students are discussed.     

If I had a magic wand I'd magic her out of the book: the rich literacy practices of competent early readers

This article explores the reading behaviours of 10 young competent nursery and reception children, The 10 children were selected from a group of 54 case study children involved in the national Bookstart evaluation study, Bookstart: Planting a Seed for Life (2005). This group of young readers, from different socioeconomic groups, were identified as reading in advance of their peers. The first part of this article explores the children's attitudes to reading, their responses to selected texts and their understanding of early phonological and letter knowledge. Second, the article reports on the findings from interviews with the parents of these children in order to illuminate the home literacy events that shape these young children's reading competences. This article is based on the larger scale national evaluation study of the Bookstart project, Bookstart: Planting a Seed for Life (2005). The evaluation was set up to explore the effectiveness of the Bookstart programme and the impact of early book giving on the first national cohort of Bookstart children as they entered school.

Economic rationalism and the politics of education in Australia

Until the mid‐1970s, the politics of urban school desegregation concentrated almost exclusively on the attainment of some form of racial balance. The racial balance paradigm became the focal point for desegregation planners and for local, state and national dispute about ‘forced bussing’. However, in its 1977 Milliken II ruling, the Supreme Court added critical new elements to the urban school desegregation paradigm. By affirming a desegregation plan which included remedial education components in all‐minority schools, and which required state participation in financing these components, Milliken II heralded a new era of urban school desegregation. Resource issues and school effectiveness issues joined racial balance issues in the crucible of desegregation politics. In this chapter, the post‐Milliken politics of urban school desegregation are highlighted through examination of the St Louis and Kansas City cases. New goals, new issues, new alignments of interests and new political strategies are apparent, presenting new challenges to students of urban education policy and politics.

More than a picture: helping undergraduates learn to communicate through scientific images

Images are powerful means of communicating scientific results; a strong image can underscore an experimental result more effectively than any words, whereas a poor image can readily undermine a result or conclusion. Developmental biologists rely extensively on images to compare normal versus abnormal development and communicate their results. Most undergraduate lab science courses do not actively teach students skills to communicate effectively through images. To meet this need, we developed a series of image portfolio assignments and imaging workshops in our Developmental Biology course to encourage students to develop communication skills using images. The improvements in their images over the course of the semester were striking, and on anonymous course evaluations, 73% of students listed imaging skills as the most important skill or concept they learned in the course. The image literacy skills acquired through simple lab assignments and in-class workshops appeared to stimulate confidence in the student's own evaluations of current scientific literature to assess research conclusions. In this essay, we discuss our experiences and methodology teaching undergraduates the basic criteria involved in generating images that communicate scientific content and provide a road map for integrating this curriculum into any upper-level biology laboratory course.     

Organizational Effectiveness of 2-Year Colleges: The Centrality of Cultural and Leadership Complexity

The central purpose of this study was to examine the extent to which community college faculty and administrators' perceptions of the organizational effectiveness of their institutions was related to their perceptions of the cognitive and behavioral complexity of the organizational cultures and the leadership roles performed by senior campus officials of their institutions. The findings show a strong relationship between perceptions of the organizational effectiveness of the institutions and the level of complexity in their campus cultures and the leadership behaviors of senior campus officials. These findings are discussed in terms of their implications for future research on the organizational effectiveness of colleges and universities and policy and practice initiatives that have the potential to improve the performance of these institutions.     

Job satisfaction among academic staff: An international perspective

This study examined aspects of academics'satisfaction with theirjob across the eight nations (Australia, Germany, Hong Kong, Israel, Mexico,Sweden, UK, USA). Interesting patterns emerged across countries reflectingdifferences in the international academic climate. The study also exploredpatterns of job satisfaction and dissatisfaction more closely for theAustralian data, and examined the impact of context elements, includingworking climate and atmosphere, on general levels of job satisfaction.Results indicated that factors related to the environment in which academicswork, including university atmosphere, morale, sense of community, andrelationships with colleagues, are the greatest predictors of jobsatisfaction. Implications for university management and governing bodiesare discussed.
