The records of the North American Jewish Students Appeal (NAJSA or APPEAL) contains documents on two levels of concern: those documents dealing with the NAJSA as a student-run organization promoting Jewish identity among college-aged youth; and those documents dealing with the APPEAL as a fundraising organization for several well-known student constituent organizations. The Constituents were: the Jewish Student Press Service, Lights in Action, the North American Jewish Students Network, the Progressive Zionist Caucus, Response: A Contemporary Jewish Review, Yavneh Religious Students Organization, and Yugntruf Youth for Yiddish. Documents include correspondence, financial records, minutes, press releases, information on grants awarded to student organizations for programming and publishing, student journals, and newspapers, photographs, and ephemera.

1. Resilience-based approaches are increasingly being called upon to inform ecosystem management, particularly in arid and semi-arid regions. This requires management frameworks that can assess ecosystem dynamics, both within and between alternative states, at relevant time scales. 2. We analysed long-term vegetation records from two representative sites in the North American sagebrush-steppe ecosystem, spanning nine decades, to determine if empirical patterns were consistent with resilience theory, and to determine if cheatgrass Bromus tectorum invasion led to thresholds as currently envisioned by expert-based state-and-transition models (STM). These data span the entire history of cheatgrass invasion at these sites and provide a unique opportunity to assess the impacts of biotic invasion on ecosystem resilience. 3. We used univariate and multivariate statistical tools to identify unique plant communities and document the magnitude, frequency and directionality of community transitions through time. Community transitions were characterized by 37-47% dissimilarity in species composition, they were not evenly distributed through time, their frequency was not correlated with precipitation, and they could not be readily attributed to fire or grazing. Instead, at both sites, the majority of community transitions occurred within an 8-10year period of increasing cheatgrass density, became infrequent after cheatgrass density peaked, and thereafter transition frequency declined. 4. Greater cheatgrass density, replacement of native species and indication of asymmetry in community transitions suggest that thresholds may have been exceeded in response to cheatgrass invasion at one site (more arid), but not at the other site (less arid). Asymmetry in the direction of community transitions also identified communities that were at-risk' of cheatgrass invasion, as well as potential restoration pathways for recovery of pre-invasion states. 5. Synthesis and applications. These results illustrate the complexities associated with threshold identification, and indicate that criteria describing the frequency, magnitude, directionality and temporal scale of community transitions may provide greater insight into resilience theory and its application for ecosystem management. These criteria are likely to vary across biogeographic regions that are susceptible to cheatgrass invasion, and necessitate more in-depth assessments of thresholds and alternative states, than currently available.

Ma thèse examine quatre romans de l`époque post-1960 qui s’appuient sur le genre de la littérature prolétarienne du début du vingtième siècle. Se basant sur les recherches récentes sur la littérature de la classe ouvrière, je propose que Pynchon, Doctorow, Ondaatje et Sweatman mettent en lumière les thèmes souvent négligés de cette classe tout en restant esthétiquement progressiste et pertinents. Afin d’explorer les aspects politiques et formels de ces romans, j’utilise la « midfiction », le concept d’Allen Wilde. Ce concept vise les textes qui utilisent les techniques postmodernes et qui acceptent la primauté de la surface, mais qui néanmoins essaient d’être référentiels et d’établir des vérités. Le premier chapitre de ma thèse propose que les romans prolétariens contemporains que j’ai choisis utilisent des stratégies narratives généralement associées avec le postmodernisme, telles que la métafiction, l’ironie et une voix narrative « incohérente », afin de contester l’autorité des discours dominants, notamment les histoires officielles qui ont tendance à minimiser l’importance des mouvements ouvriers. Le deuxième chapitre examine comment les romanciers utilisent des stratégies mimétiques afin de réaliser un facteur de crédibilité qui permet de lier les récits aux des réalités historiques concrètes. Me référant à mon argument du premier chapitre, j’explique que ces romanciers utilisent la référentialité et les voix narratives « peu fiables » et « incohérentes », afin de politiser à nouveau la lutte des classes de la fin du dix-neuvième et des premières décennies du vingtième siècles et de remettre en cause un sens strict de l’histoire empirique. Se basant sur les théories évolutionnistes de la sympathie, le troisième chapitre propose que les représentations des personnages de la classe dirigeante riche illustrent que les structures sociales de l’époque suscitent un sentiment de droit et un manque de sympathie chez les élites qui les font adopter une attitude quasi-coloniale vis-à-vis de la classe ouvrière. Le quatrième chapitre aborde la façon dont les romans en considération négocient les relations entre les classes sociales, la subjectivité et l’espace. Cette section analyse comment, d’un côté, la représentation de l’espace montre que le pouvoir se manifeste au bénéfice de la classe dirigeante, et de l’autre, comment cet espace est récupéré par les ouvriers radicaux et militants afin d’avancer leurs intérêts. Le cinquième chapitre explore comment les romans néo-prolétariens subvertissent ironiquement les tropes du genre prolétarien précédent, ce qui exprimerait l’ambivalence politique et le cynisme généralisé de la fin du vingtième siècle.

If readers of Great Plains Research are seeking a window on rock art research in North America, this book provides a few clear panes, a few that are hazy, and a few muddy ones. Like many edited volumes, the weaker contributions and lack of a consistent style limit the book's usefulness. Some authors target a general readership; others clearly are addressing colleagues. The book has two stated themes: the history of rock art research in North America and recent approaches to rock art analysis. Articles by Julie Francis and (jointly) David Whitley and Jean Clottes explore why rock art research has long been marginalized in North America. Unfortunately, both of these otherwise observant essays slip into advocacy of shamanism as a unifying or primary explanation for rock art, an interpretive model by no means universally accepted by today's rock art specialists.
