This article analyzes the conception of religion that appears from the religion-based asylum claims litigation in Canada. The Canadian State is compelled to respect a double obligation of neutrality and guarantee of freedom of conscience and religion, which leads it to interfere in the religious field to outline the concept of religion. The particularity of the asylum litigation reveals a functional understanding of religion, which remains nonetheless permeated with sociocultural residues. The analysis will first present the strategies of the commissioners and judges to avoid defining the religion. It will then show how the specificities of the asylum litigation, including the analysis of factual elements such as the credibility assessment, the evaluation of the risk of persecution and well-founded fear, affect the definition of religion that emerges from it.

For many workers in Ontario, the Employment Standards Act (ESA) provides the only formal measures of workplace protection. The complaints-based monitoring system utilized by the Ontario Ministry of Labour, however, makes it difficult to assess the overall prevalence of employment standards (ES) compliance in the labour force. In addition to outright ESA violations, prevailing research highlights the significance of the erosion, evasion, and outright abandonment of ES for workers' access to protection through practices such as the misclassification of workers and types of work. In this article, we report on efforts to develop a telephone-survey questionnaire that measures the overall prevalence of ES violations, as well as evasion and erosion in low-wage jobs in Ontario, without requiring respondents to have any pre-existing legal knowledge. Key methodological challenges included developing strategies for identifying ‘misclassified' independent contractors, establishing measures for determining whether workers were exempt from the ESA, and translating the regulatory nuances embedded in the legislation into easy-to-answer questions. The result is a survey questionnaire unique in the Canadian context. Our questionnaire reflects the concerns of both academic researchers and workers' rights activists. Pilot survey results show that Ontario workers do not necessarily distinguish between ES violations and other workplace grievances and complaints. With careful questionnaire design, it is nevertheless possible to measure the prevalence of ES violations, evasion and erosion. In order to track the effects of ES policies, particularly those on enforcement, we conclude by calling for the establishment of baseline measures and standardized reporting tools.

AbstractVarious natural chemicals and certain contaminants from industries present an endocrine activity. These substances are likely to act on animal and human endocrine system (deterioration or reproductive functions deficiencies, malignant tumor occurrences, etc). Nowadays, many questions related to these compounds are not resolved and the persistent character of these compounds makes it a major problem for future generations. Furthermore, diverse studies determined that natural estrogens (e.g., estrone, 17β-estradiol and estriol) and synthetic estrogen (17α-ethinylestradiol) are the most estrogenic compounds in wastewater treatment plant effluents. Thus, these estrogens can reach surface water and contaminate it. Indeed, concentrations as low as 0.1 ng/L can induce estrogenic effects in exposed aquatic organisms. This review concentrated on this type of compounds in surface water and wastewater, and a number of treatment processes are discussed with regard to their potential on endocrine disrupting chemicals removal. In the primary treatment effluent, limited removal of estrogens has been observed, while secondary treatment involving activated sludge generally reduces all estrogens effluents concentrations. The advanced processes display a high potential for removing estrogens, although they may produce estrogenic and/or carcinogenic by-products. Enzymatic processes could be an innovative strategy for estrogens removal since they show a high potential to remove aromatic compounds from wastewater.

The effective management of phosphorus in watersheds requires knowledge of the origin and magnitude of phosphorus inputs. However, for large and complex watersheds, it is impossible to determine the phosphorus mass balances by measuring the flow from each source and the rate of transfer of phosphorus originating from upstream. Because of these difficulties, we have developed a strategy based on the measurement of phosphorus mass balances during base flow periods (with no storm-flow, which means with a constant or decreasing flow). This approach was applied to the Foron River watershed (drainage area 51.5 km2, annual average water discharge 0.5 m3 /s).The Foron River, a hillside stream with a torrential flow regime, is a tributary of Lac Léman (a large meso-eutrophic lake also known as Lake Geneva). Land use within the Foron watershed is diverse, with 50% of the watershed area being in a naturally forested area (on steep upland slopes), 36% in agricultural land lying on a gentle relief of moraine deposits (70% permanent pasture and hay meadows, 30% cereal grain crops) and 3% in marshes. The population is scattered amongst four small villages, with an overall density of about 100 inhabitants per km2. Stream flow in the river was continuously monitored and automatically sampled at the outlet from 1990 to 1993. Additional grab samples were taken at various locations, springs, agricultural sub-watersheds and brooks in the naturally forested area. Total suspended solids, soluble total phosphorus, orthophosphate and total phosphorus were determined according to standard methods. In addition, sampling was carried out to determine phosphorus stored in river sediments in places that are known to be temporary sinks for sediments.To validate the efficiency of the approach, we carried out a detailed study of the point sources and the sewage systems in the watershed. Only two-thirds of domestic wastewaters were processed in treatment plants. The minimum load of point source inputs was established to be about 60 kg total P per week and many point sources (that is to say discharged at discrete locations) remained unidentified (i.e., not all households were connected to sewers, farmsteads contributed for unknown quantities of total P).During base flow periods, phosphorus was predominantly soluble and orthophosphate was found throughout the hydrographic network. Particulate phosphorus and suspended matter concentrations were negligible (respectively < 20 µg/l and <30 mg/l), were not related to flow discharge and originated mainly from point source discharges. The inputs from surface runoff on the watershed were also negligible, as reflected in the low concentrations of total phosphorus in the agricultural or forested sub-watersheds (less than 15 µg/L).Total inputs of phosphorus into the river included not only this background phosphorus (evaluated to be less than 2 kg total-P per week), but also P mainly originating from point sources. Total phosphorus exported from the outlet varied from 20 to 110 kg total-P per week but was often much lower (up to 80%) than the minimum inputs due to point sources. During these periods phosphorus can accumulate in the hydrographic network, probably in the riverbed sediments and periphyton (macrophytes were not present).The detailed pattern of phosphorus exports during these low flow periods showed that the amount of total phosphorus exported (90% soluble P) tended to increase with the weekly mean water flow, up to a water discharge rate of 0.8 m3 /s. Above this value, phosphorus export reached a plateau corresponding to a mean constant value (about 80 kg per week). Since weekly average inputs from point sources remained nearly constant, independent of stream flow, this increase in P export indicated an increase in the rate of transfer of total phosphorus from point sources discharged into the river. When the water discharge was > 0.8 m3 /s, a constant P export regime was reached as all the inputs were transported to the outlet. Consequently, output at the outlet was equal to input into the river. This approach permits the calculation of the total point sources. Knowing the inputs from point sources and the total P export at the outlet, we can calculate the diffuse sources.Significant relationships between weekly mean total-P, soluble-P or orthophosphate concentrations at the outlet and weekly mean discharge were established to validate these observations. The best fit of these measured values didn't follow a standard law of dilution because the dilution effect was attenuated by the antagonist effect due to the increase in P transport inputs from sewage with increasing discharge. ([soluble P]=0.02+ 0.148 Q-1/2 ; n=82; r2 =0.8).During base flow when Q < 0.8 m3 /s, a portion of phosphorus inputs accumulated in the river biota and sediments through deposition, biological uptake and sorption. This accumulation may explain the higher levels of total-P and the easily exchangeable P in the sediments downstream of point source discharges. The efficiency of these storage processes depends not only on water discharge, but also (secondarily) on some characteristics of the antecedent hydrological conditions. We found that the amount stored increased significantly in the weeks following large storm-flows. We assumed that this indicated the effect of an intense exchange of the P loaded sediments with unsaturated sediments that were generated by erosion of natural upstream areas. As in-stream processes alter phosphorus speciation, a part of soluble-P becomes particulate. During storm-flows following base flow periods with a discharge lower than the limit discharge, the stored phosphorus was released from both particulate and soluble forms and exported. We calculated an annual mass balance of soluble phosphorus to evaluate the amount of particulate phosphorus exported at the outlet due to the transformation of phosphorus from soluble to particulate forms. The result obtained suggested that ¼ of particulate-P (1 t per year) resulted from this speciation change.To summarize, analyses of phosphorus mass balances during base flow could lead to a new procedure to evaluate the mean total mass of P originating from point sources, without referring to field surveys. In addition, this procedure allowed the quantification of both total-P storage as well as changes in speciation that occur during transfer of phosphorus in the hydrographic network.

The terrestrial organic carbon (C) pool, estimated to 1.5 x 1015 kg C for the first meter of soil (Amundson, 2001), represents a major terrestrial elemental stock for which the recycling rate and the response to perturbations are still unknown. Under the present changing climatic conditions, C fluxes in terrestrial ecosystems could be significantly disturbed during the next decades. Indeed, the multi-annual changes in temperature and precipitation are likely to have a major impact on the net primary production and on organic matter decomposition in soils. This situation influences the production of the dissolved organic carbon (DOC) in soils, its transport to surface waters and hence, water quality. In this context, a better knowledge of the climatic and hydrologic factors influencing seasonal variations in DOC export is crucial to improve our understanding of the potential transformation of carbon stocks and fluxes in terrestrial ecosystems.The objectives of the present study were 1) to evaluate the seasonality in the relationship between dissolved organic carbon (DOC) concentrations in the stream and streamflow (Q) and 2) to quantify the impact of seasonal changes in climatic and hydrological conditions in the watershed on the DOC/Q relationship.The Hermine catchment is located about 80 km north of Montréal, Québec, Canada. An intermittent first-order stream drains the 5.1 ha catchment. Soils are Orthic and Gleyed Humo-Ferric and Ferro-Humic Podzols. The stream water was sampled daily, from 1994 to 2003, with an automatic sampler. The stream discharge was calculated from the water level above a 90º V-notch weir using a Global level sensor bubbler. Soil organic C content was analysed by the modified Walkley-Black method. Because of the high cost of DOC analysis for numerous samples, the DOC content was estimated by the relationship obtained between eight stream water samples analysed with a Shimadzu TOC analyser (Shimadzu, Kyoto, Japan) and the corresponding absorbance measured at 254 nm. From the initial year of the project, 1994, the regression used was Y=-0.05 + 32.60 X with an r2 value of 0.58 and a precision of 0.05 mg·L-1.The relationship between the DOC concentration and Q at the Hermine was positive and significant (p < 0.01) when all data were considered (n=1960). Because of the weakness of this relation (r2 =0.12), the stream samples, from 1994 to 2003, were seasonally split into 93 distinct hydrological events: 33 for winter-spring, 34 for summer and 26 for fall. A linear regression model was used to determine, for each event, the slope of the relationship between the DOC concentrations in the stream and Q. To contrast the antecedent conditions of the Hermine watershed, the events from a given season were divided into two groups. The Kruskal-Wallis test was then used to establish the link between the slope of the DOC/Q relationships on the one hand, and the environmental watershed conditions on the other hand: the climatic variables (volume of precipitation during event, mean air and soil temperatures) and the hydrological variables (stream discharge 24 h before the event, soil moisture, and ground water level).The DOC concentrations in the stream varied on an annual, a seasonal and an event basis. For the period 1994 to 2003, the annual mean concentrations, calculated from daily samples, varied from 2.0 to 2.5 mg DOC·L-1. On a seasonal basis, mean daily DOC was higher during the summer and the fall (2.9 and 2.8 mg DOC·L-1 respectively), and lower in the winter-spring (2.1 mg DOC·L-1). The relation between DOC concentrations and Q fluctuated as a function of the seasonal evolution of climatic and hydrological conditions in the Hermine catchment. For winter-spring events, 79% of the events had a DOC/Q slope lower than one. This period was characterised by high streamflow levels and high total DOC fluxes even though the daily mean DOC concentrations were low (2.1 mg DOC·L-1). The volume of precipitation during the event (p =0.041), the mean air temperature (p =0.001) and the soil temperature (p =0.009) were significantly related to the difference between events with slopes lower and higher than one. Indeed the slope of the relation increases when soil temperatures are elevated. When the temperatures are higher, DOC export increases and subsurface flow in soil horizon is enriched in DOC. Under colder temperature, the DOC production is limited and the soluble organic substances stored in soils are leached out the catchment with the high volume of precipitation and with the water coming from the snowmelt. For the summer period, there were 20 events with slopes greater than one against 14 with slopes lower than one. The soil humidity (p =0.039) and the total streamflow 24 h before the event (p=0.0003), were the two variables that significantly distinguished both slope groups. Rapid changes in DOC concentration occur during hydrological events following a long drought period. Under dry conditions, the subsurface flow in soil horizons rich in organic matter, the re-hydration of bed sediments and the hydrophobic behaviour of soil particles can all contribute to the export of very high DOC concentrations, even during small events. The relationships between DOC and Q, for the fall season, were significantly influenced by the volume of precipitation during the event (p =0.031) and the mean soil temperature (p =0.042). The events with the lower slopes showed the highest volume of precipitation during event and the lowest soil temperature. For these events occurring under wet conditions, the water originates essentially from the B and C horizons, and DOC fluctuations are then limited because of the low concentrations of the DOC in these horizons (anionic sorption of soluble organic substances by iron oxides).Best-fit from multiple regressions indicated that 40% of the link between DOC and Q was explained by the soil temperature during the winter-spring period (p =0.0001). For summer, the streamflow 24 h before events accounted for 51% of the variation in DOC/Q relationships (p =0.00001). For the fall period, the volume of precipitation during event and the soil temperature both contributed equally to the DOC/Q relationships (p =0.001). From these results, obtained from a multi-year project, it is clear that the relation between DOC and Q is a function of the variability in the climatic and hydrological watershed conditions. In a context of global warming, it is possible that warmer air temperatures have an effect on soil temperature. Thus, during winter-spring and fall periods, the duration and the intensity of the DOC production in soils will increase and the export of DOC from the watershed to other surface water system could become more important under equivalent or higher streamflow. Higher air temperature also means higher evapotranspiration by the forest during the summer period, and consequently dryer watershed conditions. A low streamflow and a low soil humidity level could be expected and then, brief rain events will sporadically flush the soluble organic carbon accumulated in the soil. The DOC export would be insignificant for that period, but the DOC would reach the highest annual level. The new knowledge on the DOC/Q relationships, at the hydrological event scale, will be added to the accumulated data on the possible effects of global warming on the carbon cycle in forested ecosystems.

AbstractThis paper examines the emergence of colonial ornithology in Upper Canada, 1791-1841, to determine the impact of empire and local contexts on the natural history activity. I argue that colonial ornithology emerged as a by-product of British imperialism that helped to reinforce British, upper- and middle-class, gender-specific white identities through practices of sportsman-hunting, taxidermy, natural theology, and the romantic-aesthetic. However, as this paper reveals, British imperial practices and ideas of ornithology relied on the participation of First Nations and Métis peoples, whose knowledge and skills were instrumental to British naturalists. The First Nations and Métis peoples therefore exerted a real presence in colonial ornithology in Upper Canada—albeit a subservient one in the British ornithological texts—as they positioned themselves as part of the ornithological trade with the collection and trading of specimens. Furthermore, British military officers, settlers, and tourists tapped into American scientific networks and knowledge systems rather than focusing solely on Britain as an imperial centre of accumulation. British imperial ideas and practices of colonial ornithology in Upper Canada therefore remained ambiguous during the early nineteenth century.

We know little about the transnational publishing experience of authors of books about scientific topics in Canada. This study therefore explores the nineteenth-century publication of a Canadian author's manuscript in the United States and Great Britain: Man's Moral Nature (1879) by Ontario physician Richard Maurice Bucke. Although this book is relatively unknown, Bucke's personal records about this, his first book, provide insights into publishing processes, from finding a publisher through to understanding book production and copyright. As the book's reception shows, Bucke not only was unable to position his scientifically-oriented book for his intended general readership but he also received criticism from medical colleagues for his attempt. Bucke's emphasis on obtaining a North American readership, however, adds further evidence of a continental market described by book history scholars.

In the course of time, families disperse and kin relationships change. The differences between the genders in migration and the resulting differences in spatial dispersion of the children from their fathers were analyzed in two largely rural populations in the mid-19th century. The analyses were performed mainly on the Swedish population in the northern coastal Skellefteå region, where data on both genders was available. The results were used to estimate gender differences among a native-born population in the northern U.S., where information about women was limited. Most adult children resided in the same places as their fathers, and the proportion of co-resident sons was the same in both populations. However, more daughters than sons were located elsewhere in Skellefteå and probably also in the U.S. The distances separating relatives were, however, greater in the U.S. Men lived in patrilineal clusters to a greater extent than did women due, in part, to patrilineal inheritance and virilocal marriages. The results were discussed with reference to migration and marriage patterns, spatial organization and economic differences.
