Image et Sciences Sociales

Contrary to oral interviews, statistics or primary sources in print, the use of film does not occupy an important place in the training of social scientists. Yet, as this article argues, before film and video can become standard data gathering tools, social scientists need to reflect on the ways filming techniques are taught. To do so, this article offers an account of a filming course taught for several years to third year students at the university of Tours.     

A radiocarbon chronology for the complete Middle to Upper Palaeolithic transitional sequence of Les Cottés (France)

The Middle to Upper Palaeolithic transition is the key period for our understanding of Neanderthal and modern human interactions in Europe. The site of Les Cottés in south-west France is one of the rare sites with a complete and well defined sequence covering this transition period. We undertook an extensive radiocarbon dating program on mammal bone which allows us to propose a chronological framework of five distinct phases dating from the Mousterian to the Early Aurignacian at this site. We found that the Mousterian and Châtelperronian industries are separated from the overlying Protoaurignacian by a gap of approximately 1000 calendar years. Based on a comparison with Upper Paleolithic sites in Europe we see an overlap in the ages of Châtelperronian industries and Aurignacian lithic assemblages, which are usually associated with Anatomical Modern Humans, which is consistent with an acculturation at distance model for these late Neanderthals. The Proto and Early Aurignacian appear contemporaneous indicating that this transition was rapid in this region. Anatomically Modern Humans are present at the site of Les Cottés at least at 39,500 cal BP roughly coincident with the onset of the cold phase Heinrich 4.     

A numerical taxonomic study of Late Carboniferous Spiriferidina from eastern Australia

Species of Late Carboniferous spiriferidines belonging to the genera Alispirifer, Licharewia, Neospirifer, Spirifer, Liriplica, and Spinuliplica are analyzed on the basis of fifty-two different morphological characters. A computer program for cluster analysis is used which ensures that each character is given equal weighting, and the degrees of similarity between species are measured objectively.

The resulting classification is similar to the conventional one, with three exceptions. It is recommended that Spinuliplica spinulosa Campbell and Liriplica alta Campbell be assigned to one genus, Liriplica; Licharewia bootiensis Thompson be assigned to the genus, Alispirifer; and Spirifer pristinus (Maxwell) be reassigned to the genus Neospirifer.

A method of graphical analysis using contour diagrams is also presented as an alternative method of illustrating the relationships between the different species of spiriferidines.     

THE 'BLOB'

Canada will remember 1985 as the year of the ‘Blob,’ that mixture of toxic chemicals found in the St Clair River that attracted national attention. The ‘Blob’ was discovered by divers from the Great Lakes Institute (gli) of the University of Windsor, who were engaged in taking samples of sediment from the bottom of the river. The oily sludge was found to be a mixture of nasty chemical compounds - including dioxins. In the words of one government scientist, it was the most contaminated material ever found in the Great Lakes! Traces of the dread dioxin were found in the drinking water of municipalities downstream, and citizens demanded action from all levels of government. Did the chemicals come from spills from Chemical Valley industries? or industrial sewers? or seepage from deep wells where chemical waste has been stored? Do these toxic contaminants bioaccumulate in the food chain? And what is their effect on humans? No one knows the answers to these questions, but the problems have not gone away. One important result has been a great increase in research efforts. The Gli had been engaged for three years in research in the Essex region on four toxic contaminants — lead, cadmium, pcbs, and ocs (octachlorostyrene) under a contract with the federal Department of Environment. This research indicated that these contaminants are widespread in the sediments and clams of the rivers and Lake St Clair- and also in the soil and plants of the region. The latter finding is of concern, since recent research has shown that food (not drinking water) is the chief source of many contaminants to the human body. Since the ‘Blob’ findings, the Gli has received grants from the World Wildlife Fund and the Ontario Ministry of the Environment to pursue its research into toxic contaminants in the ecosystem. The ‘Blob’ incident has been a justification for the existence of the Great Lakes Institute. It demonstrated that university institutes could bring to public attention environmental hazards that may be concealed or minimized by private companies and overlooked or condoned by government agencies. The multidisciplinary cli was formed at the University of Windsor in 1981 to provide an alternative to government research on the Great Lakes. In Ontario at that time there was no university-based organization doing Great Lakes research, though all the Great Lakes states had such university institutes.     

Feminist Activism and the Politics of Reform: When and Why Do States Respond to Demands for Gender Equality Policies?

Under what conditions is gender equality policy advocacy successful? This article examines a segment of the largely quantitative comparative political science literature that seeks to answer this question. Recent scholarship emphasizes such factors as the strength of women's movements and the forms of opposition to which their policy demands give rise. However, one consequence of this approach is that the role of strategic choices made by feminist policy advocates is underestimated in explaining their successes. The article argues that understanding variation in the outcomes achieved by women's rights advocates requires close attention to the strategic capacity of policy entrepreneurs, assessed in terms of three inter‐related activities: (1) ‘framing’ policy demands; (2) forming and managing civic alliances; and (3) engaging with state entities without compromising organizational autonomy.
