Anti-Canadianism: Explaining the Deep Roots of a Shallow Phenomenon

Anti-Americanism is often said to be a central element of Canadian identity. Recently, however, its counterpart—anti-Canadianism—emerged in the United States. This article examines these expressions of anti-Canadianism, situating the phenomenon within the two countries' historical, ideological-discursive, and political relationships. The paper suggests anti-Canadianism in the United States stems from a mix of anti-French sentiment, a refusal to accept the distinctiveness of English-speaking Canada, and a growing divergence of value orientations between the two countries. The paper argues further that anti-Canadianism must be viewed (like its counterpart) according to its political uses on both sides of the border.On dit souvent que l’anti-américanisme constitue un élément central de l’identité canadienne. Récemment, toutefois, sa contrepartie, l’anticanadianisme, est apparue aux États-Unis. Cet article examine ces expressions de l’anticanadianisme en situant le phénomène dans les relations historiques et politiques et le débat idéologique entre les deux pays. Selon le document, l’anticanadianisme aux États-unis résulte d’un mélange de sentiment antifrançais, d’un refus d’accepter le caractère distinct du Canada anglais et d’une divergence croissante des valeurs entre les deux pays. L’auteur du document soutient également que l’anticanadianisme doit être examiné (comme sa contrepartie) d’après ses utilisations politiques des deux côtés de la frontière

Tomol's and the "carrying of many people": Indigenous control of the sea in the Santa Barbara Channel

The Indigenous Chumash people of the California coast relied heavily upon the wealth of maritime resources that the Santa Barbara Channel provided. In order to access these vast resources, the use of advanced sewn vessels, known as the Tomol, were used and were of inestimable importance to the formation of their complex society. It is the purpose of this thesis to analyze the evidence of these vessels at the village site of Helo' (site CA-SBA-46) on Mescalatin Island in order to determine what effects Spanish colonization and missionization had on this integral technology. Additionally, this thesis attempts to synthesis a number of different lines of evidence in order to make such determinations. This includes physical remains of vessels themselves if identified, artifactual remains of tools necessary to build tomol's as well as the tools used in gathering maritime resources, along with historic and ethnographic records of tomol construction and usage. Finally, it is hoped that this thesis will inspire further study of Indigenous maritime cultures in other regions where physical remains of the vessels used are limited or non-existent. By demonstrating that such maritime culture can be studied through analysis of associated materials, it is hoped that the dearth of information of vessels of which there are limited remains will no longer be left in the dark

Ecology of the ichthyofauna in three temporarily open/closed estuaries on the Natal coast

The ichthyofauna of three small Natal estuaries, the Mhlanga, Damba and Zotsha was sampled over a period of two years. A total of 68 kinds of fishes representing 24 families, 39 genera and 56 species were captured during this study. Forty seven kinds of fishes were recorded in the Mhlanga of which Gilchristella aestuaria,Oreochromis mossambicus, Valamugil cunnesius, Valamugil sp. and juvenile mugilids numerically dominated. In terms of biomass, O. mossambicus, V. cunnesius, Liza alata, Myxus capensis and Mugil cephalus dominated the ichthyofauna of the Mhlanga. In the Damba, 24 kinds of fishes were recorded. The most abundant fishes captured were Glossogobius callidus, M. capensis and O. mossambicus. M. capensis, M. cephalus, O. mossambicus and G. callidus dominated the fish biomass captured in the Damba. A total of 56 kinds of fishes were recorded in the Zotsha during this study. The ichthyofauna of the Zotsha was numerically dominated by juvenile mugilids, G. aestuaria, O. mossambicus, Rhabdosargus holubi, Terapon jarbua, Ambassis productus and G. callidus. The species which dominated the fish biomass in the Zotsha were O. mossambicus, L. alata, Valamugil robustus, Valamugil buchanani, M. capensis, M. cephalus and V. cunnesius. Classifying the species captured according to whether they were resident estuarine species, freshwater species, estuarine-dependent marine species and marine species revealed that the first three groups were all well represented in the systems. The only system in which marine species made any significant contribution to the ichthyofauna was the Zotsha. Oreochromis mossambicus was the dominant freshwater species in all three estuaries during this study. Gilchristella aestuaria and Glossogobius callidus were the principal estuarine species in the Mhlanga and the Damba respectively. Both G. aestuaria and G. callidus were the dominant estuarine species captured in the Zotsha. The principal estuarine-dependent marine fishes captured in the Mhlanga were V. cunnesius, Valamugil sp., juvenile mugilids, M. capensis, M. cephalus and L. alata. In the Damba, M. capensis and M. cephalus were the dominant estuarine-dependent marine species and in the Zotsha juvenile mugilids, R. holubi, T. jarbua, A . productus, M. capensis, V. cunnesius, V. robustus, M. cephalus and L. alata predominated. The results of this study indicate that the estuaries are dominated at different periods by different assemblages of fishes. This is linked to the spawning and migration patterns of the various species as well as the hydrological regime of each estuary. During the winter these systems are normally closed with relatively deep waters and high food resource and habitat availability. Freshwater and estuarine species mainly inhabit the upper reaches of the systems while estuarine-dependent marine species mainly occupy the middle and lower reaches and dominate the fish community. When these systems open with the onset of the spring/summer rains, adult and sub-adult estuarine-dependent marine species emigrate to the marine environment and juveniles begin recruiting into the systems. Spring is also the peak breeding period of resident estuarine and freshwater species, resulting in an increase in the contribution of these fishes to the overall population during this period. When closed estuaries open many of them drain and this results in the fishes concentrating in the lower reaches of the system where moderate water depths are present, thus further contributing to an increase in the proportion of freshwater and estuarine species in this region. The breaching of closed estuaries also results in a slump in food resources and habitat availability. Competition and possible increased vulnerability to avian predation (due to the shallow nature of the systems), may contribute to a decrease in the proportion of estuarine and freshwater species in summer. The prolonged spawning and recruitment of 0+ juveniles of estuarine-dependent marine species results in an increase in the proportion of these fishes present in the estuaries during summer. In autumn, these systems normally close, water levels rise and available food resources and habitat increase. This allows the redistribution of freshwater and estuarine species upstream, leaving estuarine-dependent marine species to dominate the middle and lower reaches. Although temporarily open/closed estuaries along the Natal coast may not be as diverse as permanently open estuaries in terms of their ichthyofauna, their importance must not be underestimated since by providing a continuous sequence of sheltered habitats along the coast they may contribute significantly to the viability of estuarine-dependent marine fish stocks

Biogeography and community structure of fishes in South African estuaries

The biogeography and community structure of the fishes of South African estuaries was investigated. In all, 109 systems were examined representing two broad types: temporarily closed and permanently open estuaries. Multivariate analyses of the fish communities identified three biogeographic regions. A cool-temperate region extended along the west and southwest coasts; a warmtemperate zone stretched along the south, southeast and east coasts and a subtropical region occurred along the east coast. The boundaries of these biogeographic regions were also delineated. The general physico-chemical characteristics of the estuaries within the three biogeographic regions also reflected regional differences in climate, rainfall and ocean conditions. Estuarine temperatures followed the trend for marine coastal waters, decreasing from subtropical estuaries toward cool-temperate systems. The low rainfall and runoff in the warm-temperate region together with high evaporation rates and strong seawater input resulted in higher salinities in these estuaries. These factors also accounted for the predominantly clearer waters in warm-temperate estuaries. The estuaries in the three biogeographic regions were also shown to contain somewhat distinctive fish assemblages. Temperature and salinity appeared to be the two main factors affecting the distribution and abundance of fishes in South African estuaries. Subtropical systems were characterised by fishes mostly of tropical origin as well as certain south coast endemic species. Warm-temperate estuaries were dominated by endemic taxa with some tropical species also present. The fish fauna of cooltemperate estuaries mostly comprised south coast endemic species with cosmopolitan and temperate taxa also present. Certain functional components of the ichthyofauna also exhibited slight differences between regions. Freshwater fishes were a major component of closed subtropical estuaries while estuarine resident species were more abundant in warm-temperate estuaries. Overall, estuarine-dependent marine species dominated the fish fauna of the estuaries in all biogeographic regions, signifying that South African estuaries perform a vital nursery function for this group of fishes. Slight differences were also apparent in the trophic structure of the fishes; these were related to environmental differences between regions. Zooplanktivores and fishes that feed on aquatic macrophytes/invertebrates assumed a relatively higher importance in warm-temperate systems. Overall, detritivores dominated the estuarine fish fauna in all regions, indicating that detritus forms the main energy source in South African estuaries

General Motors Company: Restructured to Rediscover American Innovation

Many analysts predicted that General Motors was not salvageable. However, after a government-backed restructuring, the company seems to be doing much better. The big question is whether the turnaround is sustainable. The company is investing heavily in technology in an effort to continue its record of success. This case examines GM up to its reorganization and also details its current strategies

Mode-Locked Diode Laser for Precision Optical Frequency Measurements

Abstract: This thesis presents an actively mode-locked diode laser as the source of an optical frequency comb with a bandwidth of at least 200 GHz. A mode-locked laser is composed of a broadband spectrum of discrete frequencies -a comb -that interferes, generating a pulsed laser output. The spectral width of the comb is inversely proportional to the temporal pulse width. In this research, an external cavity is introduced to a diode laser, and the laser's gain medium is directly modulated using an RF signal. Using a Michelson interferometer for autocorrelation measurements, pulses as short as 10 ps have been observed. A scanning Fabry-Perot interferometer was constructed to directly observe the comb, but implementation has not been successful due to alignment difficulties. It is believed that pulses as short as 1 ps could eventually be generated, corresponding to a comb width of between 318 THz and 1 THz. When completed, the optical frequency comb will be used to make precision optical frequency measurements in the Ultra-cold Atomic, Molecular and Optical physics laboratory. -2 - Acknowledgements With the sincerest gratitude I can offer, I would like to thank the following people: Dr. Set

Libertarian populism, neoliberal rationality, and the mandatory long-form census: implications for sociology

Open accessThis article argues the Canadian government’s decision in 2010 to eliminate the mandatory long-form census constitutes a mobilizing appeal to libertarian populism commensurate not only with neoliberal concepts of individualism, private property, and the role of the state, but also with a redefinition of what counts as valid argumentation and a legitimate basis for making knowledge claims. This rationale has implications for sociological research and theory, for the profession of sociology, and for a sociological vision of society.Ye

Bio-Optical Properties of the Labrador Sea

Three cruises were conducted during fall and spring in the Labrador Sea to investigate the effects of bio-optical properties on satellite retrievals of phytoplankton chlorophyll in this important high-latitude ecosystem. Taxon-specific and regional differences were found. Diatoms had similar to 1.5 lower chlorophyll-specific absorption but significantly higher reflectance ratios than prymnesiophytes. Particulate absorption at 443 nm for total, phytoplankton, and detrital\u27\u27 fractions was related to chlorophyll, but values were lower than reported for lower latitudes. Decreased particulate absorption is attributed primarily to pigment packaging, while low backscattering to scattering ratios result from a lower relative abundance of bacteria and picophytoplankton with more large phytoplankton. Soluble absorption was not related to chlorophyll. A four-component model with low, variable backscatter fractions and the observed absorption coefficients for phytoplankton, detritus,\u27\u27 and soluble materials reproduces the measured reflectance spectra. Global chlorophyll algorithms tend to underestimate biomass at high latitudes, whereas regionally tuned algorithms provide more reliable retrievals. Taxon-specific algorithms show promise, but given limited ranges, small sample sizes, and overlapping reflectance ratios they remain premature
