La présente étude se concentre sur le travail de Nancy Fraser sur la justice sociale, lequel a suscité beaucoup d’intérêt dans la littérature au cours des dernières années. La reconnaissance et la redistribution sont les deux piliers originaux de son approche: les désavantages dont souffrent les gens dus au dénigrement culturel ou à la privation économique. Ces deux concepts servent à diagnostiquer et fournir le soutien moral aux multiples luttes que les victimes d’injustice entreprennent avec l’objectif d’établir une participation plus égalitaire à la société. Cependant, que peut-elle dire cette approche des groupes qui sont marginalisés et cherchent l’autogouvernance (ou la séparation même) plutôt que l’intégration dans la société? Le travail de Fraser manifeste une résistance envers les droits du groupe, et un silence quant à l’autodétermination. Mon intervention prend comme objectif d’inclure ces formes d’injustice dans son approche, la rendant plus sensible aux dynamiques des groupes et capable de répondre à leurs revendications trop souvent négligées sous prétexte de l’égalité. La question est, l’égalité de qui? / The focus of this study is Nancy Fraser’s work on social justice, which has gained prominence in the literature over the past few years. The two original pillars of her approach are redistribution and recognition – the injustices that individuals face as a result of economic hardship or cultural denigration. These two concepts serve to diagnose and provide moral backing to the multiple struggles that individuals undertake with the aim of a more equitable way of participating in society. But what does this approach have to say about marginalized groups who seek greater autonomy, or perhaps even separation, rather than further participation in society? Fraser’s work has manifested resistance to sanctioning group difference, and silence on the issue of self-determination. I aim to build these claims into her approach, ultimately to render it more sensible to group dynamics and more capable to respond to their demands all too often neglected under the pretext of equality. The question is, equality of whom?

The submarine geomorphology of Goletas Channel - Hardy Bay - Shusharti Bay is a record of environmental change, defined by sediment deposition since the late Pleistocene draped over glacially sculpted physiography. Sea level change, contiguous with waning ice extent at the termination of the Fraser Glaciation, triggered an oceanographic transition within Goletas Channel from a low energy closed embayment to a higher energy open channel environment. Morphologic evidence of lower sea level position is observed from sequence stratigraphy in Hardy Bay and suggests regression to 74 m below present. Stratigraphy also shows a correlation between sea level transgression and turbidity current flows in northwest Goletas Channel, and although triggering mechanisms remain elusive, they are likely related to reworking of glacial sediments concomitant to initial open channel conditions. Holocene sediment accumulation has been highest in southeast Goletas Channel, represented by mud with interstitial gas, and has been reworked by tidal currents into contourite structures. A combination of high-resolution multibeam bathymetry, seismic and core samples are used to study the geomorphology of the region.

In many rivers, dams have interrupted the connectivity of migration routes for fish. While fishways can provide access between downstream and upstream habitats, it is important that passage can occur with minimal delay, energy expenditure, and physiological stress. The research presented here is based on investigations into fishway attraction and passage for the Gates Creek sockeye salmon (Oncorhynchus nerka, Walbaum) stock at the Seton River dam in British Columbia. The first part of this thesis examined the effect of changes in water discharge from the dam on the relationship between the physiological condition of sockeye and their behaviour in approaching the fishway entrance. Fish were caught and non-lethally biopsied under three normal operating discharge conditions at Seton River dam, and subsets of sampled fish were implanted with radio transmitters and released downstream of the dam. Indices of physiological stress and exhaustive exercise (e.g. plasma cortisol, glucose, lactate, osmolality and hematocrit) did not differ among the water discharge levels that were examined. Fish delayed in the tailrace below the fishway entrance significantly longer under intermediate discharge (19.9 h @ 12.7 m³s‾¹) than either the high discharge (9.3 h @ 15.8 m³s‾¹), or the low discharge (7.0 h @11.0 m³s‾¹;) conditions (P = 0.022, and P = 0.015, respectively). Delay time was similar under high and low discharge conditions (P = 0.617), and passage success was found to be independent of discharge (P = 0.356). The second part of this thesis investigated how prior physiological condition and subsequent swimming energetics and behaviours effected fishway passage success. Fish were captured and biopsied, before being implanted with electromyogram (EMG) transmitters and released near the downstream entrance of the fishway. Very few differences existed between successful and unsuccessful fish in body size, initial plasma physiology and energy state, and mean swim speed and energy use during passage. However, plasma Na+ concentration was significantly lower in unsuccessful fish (P = 0.022), which is suggestive of a depressed ionic state for unsuccessful fish. Generally, fish did not employ burst swimming during successful or failed attempts at passage, indicating that failure was probably not related to metabolic acidosis.

Oceanic islands have been used as model systems for studies of evolution and speciation as the range of island sizes coupled with their known geological chronosequence make them ideal systems for the study of spatial and temporal variations in species diversity and distributions. These processes also occur on continental islands and mainland habitats but features of oceanic islands, notably their clearly delimited boundaries, natural isolation and simple geological composition make them more amenable to study. The perched dune lakes of Fraser Island, Australia share many of the properties of oceanic islands. The naturally isolated formation of the perched lakes, clearly delimited boundaries of the freshwater habitat and phase difference compared to the surrounding, terrestrial environment have significant implications for the biota these lakes support. Inhabitants of the perched dune lakes consist of the aquatic and semi-aquatic descendents of colonisers that were able to traverse a land barrier and survive in the oligotrophic, acidic waters over subsequent generations. Barriers to ongoing gene flow among lake populations, are however likely to be different for species with different life history characteristics. I therefore sought to assess the effects of three different life history characteristics on post-colonisation interpopulation gene flow. A representative species was selected to represent one of each of the following life history characteristics: * Aquatic species confined to lake for entire life cycle - freshwater shrimp Caridina indistincta. * Semi-aquatic species capable of terrestrial dispersal - freshwater turtle Emydura krefftii. * Semi-aquatic species capable of aerial dispersal - odonate Orthetrum Boumiera. 137-250 individuals were sampled per species across six lakes separated by 1-6km. Regions of the mitochondrial genome were targeted and molecular screening methods developed and employed to assess the relative levels of post-colonisation gene flow among lake populations. Parsimony analysis of the 25 unique haplotypes identified in the species with no apparent inter-lake dispersal mechanism, the freshwater shrimp Caridina indistincta, demonstrated that there was no sharing of derived haplotypes among lake populations. Star shaped genealogies were identified in four lake populations indicative of a population expansion and mismatch distribution analysis confirmed a recent population expansion estimated to have occurred no more than 200,000 years ago. This demonstrates that each of the perched dune lakes was colonised by C.indistincta soon after their inception but that no ongoing gene flow among lake populations has occurred. The population genetic structure of the species assessed which is capable of terrestrial dispersal suggests that although this species of freshwater turtle, Emydura krefftii, is capable of overland dispersal, gene flow among lake populations is limited. Even at the small spatial scale examined in this study, E.krefftii populations displayed a pattern of isolation by distance (r=0.854, p&lt0.03). Nested clade analysis also suggested a pattern of restricted gene flow with some long distance dispersal in recent times with long distance dispersal and a possible range expansion occurring historically. The species examined in this study that displayed the most extensive gene flow among lake populations was the dragonfly Orthetrum boumiera. No relationship was found between genetic and geographic distance (r= -0.0852, p&gt0.05) and nested clade analysis could not identify a geographical association among haplotypes, indicative of panmixia. While larval life stages of this species are fully aquatic, the winged adult stages of this species appear to be connecting seemingly isolated lake populations, at least at the spatial scale examined here. The results of this study have demonstrated that these perched dune lakes provide 'island like' models for recent biogeographic processes. The pattern of colonisation and subsequent diversification identified in these populations takes the form of insitu 'genetic radiations' with those populations that are isolated forming monophyletic clades endemic to a single lake. The genetic diversity and endemism identified in this study has occurred over much smaller temporal (&lt500,000 years) and spatial (&lt6.5km) scales than in studies of oceanic island fauna. However, the mode of formation of the perched dune lakes and the implications that their natural isolation and abiotic genesis have for the evolution of colonisers of these unique habitats has resulted in them being analogous to true oceanic islands.

Den här uppsatsen behandlar idiomatiska uttryck i det svenska språket. Huvudsyftet har varit att undersöka i vilken utsträckning det svenska folket känner till betydelsen av ett utvalt antal idiom samt också i vilken mån dessa idiom används. Undersökningen genomfördes med enkäter där 139 informanter, varav ungefär hälften gick i högstadiet och den andra hälften var över 50 år, fick kryssa i flervalsfrågor om betydelse och användning för 20 idiom. Resultatet visade att de äldre informanterna inte bara hade en bättre kännedom om idiomens betydelser, utan också använde sig av idiomen i större utsträckning än de yngre. Vidare gick det att utifrån resultatet se att några av idiomen, främst "Göra en björntjänst", håller på att genomgå en förändring i sin betydelse medan andra idiom, såsom "Vara en katt bland hermeliner", verkar vara på väg att försvinna ur vårt språk.

Threespine stickleback (Gasterosteus aculeatus) and juvenile chinook salmon (Oncorhynchus tshazvytscha) co-occur during high tide in tidal channels of the Fraser River estuary. Given the high density of resident stickleback, there is the potential for strong interactions within and between the two species. Inter- and intra-specific interactions were tested by means of laboratory experiments, with support from field studies. Laboratory experiments placed stickleback and chinook in mixed and single species groups. The levels of aggressiveness were quantified, along with prey choice between surface (Drosophila), midwater (Artemia), and benthic (Tubifex) prey; microdistribution was also recorded. The experiments demonstrated that stickleback were highly aggressive towards chinook, and would drive them away from optimal feeding territories. Chinook consumed surface prey only when tested with stickleback, exploiting benthic and midwater prey when feeding alone. Stickleback demonstrated no significant difference in diet between single and mixed species trials, which is consistent with the supposition of strongly asymmetrical competition for food and space. Field data lend further support to this premise; a marked difference observed in diet suggests microhabitat partitioning between the two species, with stickleback feeding on benthos and chinook largely consuming surface prey. This thesis proposes that interactive segregation is an important process between sympatric stickleback and juvenile chinook in estuarine tidal channels and might have important implications for Fraser chinook stocks. / Science, Faculty of / Zoology, Department of / Graduate

Over the past several decades, naturally occurring populations of Fraser fir (Abies fraseri) in the Black Mountains of North Carolina have been heavily impacted by both direct and indirect anthropogenic disturbances, including logging and logging- associated fires, and high mortality rates due to the introduction of the exotic insect, balsam woolly adelgid (BWA) (Adelges piceae). The decline in Fraser fir is particularly concern because it serves as a foundation species within the spruce-fir forests of the Southern Appalachian Mountains. Our objectives for this research were to 1) use current stand structure to infer whether Fraser fir trees are experiencing a cycle of regeneration-mortality that will lead to eventual decline of the population, 2) determine what role, if any, the site-specific geographic variables of slope, elevation, aspect, and land use history have on stand structure, mortality, and BWA infestation level, and 3) analyze repeat aerial photography to examine broad trends of spruce-fir forest cover change caused by anthropogenic disturbance and the BWA. In order to understand stand structure, mortality, and infestation levels, we conducted detailed field surveys of Fraser fir trees throughout the Black Mountains using 44, fixed-radius circular sampling plots. These plots were placed throughout a series of aspects, elevations, and disturbance types in order to understand geographic variability among these variables. An analysis of 4 repeat aerial photographs and corroborating ground photographs revealed broad spatio-temporal trends of spruce-fir regeneration and mortality from 1954 to 2006. Our results indicate that Fraser fir stands at higher elevations are currently in a state of recovery; whereas stands at lower elevations appear to be more susceptible to BWA-induced mortality. Changes in forest cover area from 1954 to 2006 were influenced greatly by direct and indirect anthropogenic disturbance. Our results call attention to the significant impact that direct and indirect anthropogenic disturbance has had on Fraser fir stand structure, but also provide evidence for the ability of an imperiled ecosystem to recover from high rates of insect caused mortality. / Master of Science

During the Fraser River gold rush of 1858, over 30,000 goldseekers invaded the Aboriginal lands of southern British Columbia, setting off Native-White conflicts similar to the Indian Wars of the American Pacific Northwest. Prior to the establishment of the Colony of British Columbia, 19 November 1858, British sovereignty was marginal and the Fraser gold fields clearly an extension of the American West. The Native world was not defined by the 49th parallel, nor the kind of violence that crossed the international border with the expansion of the California mining frontier. These goldseekers, in prosecuting military-like campaigns, engaged in significant battles with First Nations, broke the back of full-scale Native resistance in both southern British Columbia and eastern Washington State, and brokered Treaties of Peace on foreign soil. The very roots of Native sovereignty, rights and unrest, current in the province today, may be traced to the 1858 gold rush. This dissertation maintains that British Columbia's 'founding' event has not been explored due to the transboundary nature of the subject. It has little or no presence in Canadian historiography as presently written. The year 1858 represents a period of exceptional flux and population mobility within an ill-defined space. I argue that the key to the Fraser Rush is to be found south of the border: in geographic space (the Pacific Slope) and in place (California mining frontier). It examines the three principal cultures that inhabited the middle ground of the gold fields, those of the Fur Trade (Hudson's Bay Company and Native), Californian, and British world views. The year 1858 represents a power struggle on the frontier: a struggle of local Indian power, the entrance of an overwhelming outsiders' power, transplanted locally and directed largely from California, and regional and long-distance British power. It is a clash of two "frontier" creations: that of "California culture" and "fur trade culture" that not only produced violence but the formal inauguration of colonialism, Indian reserves, and ultimately the expansion of Canada to the Pacific Slope.
