Cellulose nitrate artifacts from the collections of the Queen’s University Master of Art Conservation Program and Glanmore National Historic Site were examined and treated by graduate students in the Master of Art Conservation Program at Queen’s. Each object was in a varied state of degradation with unique condition problems. Under the supervision of the artifacts conservation professor, graduate students identified the materials constituting their objects and tested various treatment methods for consolidation and structural repair. Paraloid® B-67 in n-butanol and Aquazol® resins in isopropanol and distilled water were found to be effective in different roles, depending on the object and its state of degradation. This paper will discuss the factors that influenced decision-making for each object, with the aim of expanding interventive treatment strategies for cellulose nitrate objects. [ABSTRACT FROM AUTHOR]

This paper examines the Chicago sociologist William F. Ogburn's (1886–1959) views about technological unemployment, which were intimately connected to his analysis of the social impacts of technological developments and resulting social problems due to cultural lag. We trace the development of his views as seen through his well‐known 1922 book, Social Change with Respect to Culture and Original Nature, his important contributions to the President's Research Committee on Social Trends (1933), and his lesser‐known pamphlets designed for a broader audience—Living with Machines (1933), You and Machines (1934), and Machines and Tomorrow's World (1938). He used these pamphlets to educate the public about the dangers of new machines and technological unemployment. In doing so, he drew upon sociological analysis in his professional scholarly writings and his long‐standing personal interests in social betterment and social reform. Our analysis also calls into question the adequacy of existing scholarship on Ogburn that has emphasized his commitment to a statistical, dispassionate, and "objectivist" approach to social science research. We call for a revised, richer, and more complex view of Ogburn's work and legacy as one of the nation's leading social scientists during the first half of the 20th century. [ABSTRACT FROM AUTHOR]
