The notion of citizenship, while a basic human right, has come under scrutiny. It was once assumed a liberal inspired regime of citizenship rights would reign as the primary ideological perspective in the Western world, however this has not been the case. Numerous competing paradigms have questioned the premise upon which liberal guarantees of citizenship rights are based. In particular, communitarianism has subjected liberal rights discourse to a closer examination. Communitarian theory holds that universalist principles negate any articulation of community and its internal diversity, such as cultural citizenship. It is this understanding of citizenship that has taken hold in Canada. The Canadian political experience illustrates a number of attributes associated with communitarian thought. It is a collectivist society that articulates a notion of the common good, acknowledges the internal diversity of its citizens and possesses a highly developed deliberative democratic process. To this end, Canada can be described as being more communitarian than liberal in nature in the process it has adopted to address citizenship rights. However, the type of commuIiitarianism displayed in Canada differs from the political models examined by such scholars as Michael Sandel, Iris Marion Young or Will Kymlicka. Cultural citizenship rights are fluid and malleable in Canada. While no clear guarantees of citizenship rights exist, there is a common commitment by Canadians to engage in a fair, open and inclusive deliberative process. This model is unique to Canada; it cannot be exported in that it is a product of Canadian political culture. As a result, the contemporary demands of cultural citizenship are dealt with effectively and democratically in Canada in that the proper mechanisms for public deliberation exist.

This study examined annual variation in phenology, abundance and diversity of a bee community during 2003, 2004, 2006, and 2008 in recovered landscapes at the southern end of St. Catharines, Ontario, Canada. Overall, 8139 individuals were collected from 26 genera and sub-genera and at least 57 species. These individuals belonged to the 5 families found in eastern North America (Andrenidae, Apidae, Colletidae, Halictidae and Megachilidae). The bee community was characterized by three distinct periods of flight activity over the four years studied (early spring, late spring/early summer, and late summer). The number of bees collected in spring was significantly higher than those collected in summer. In 2003 and 2006 abundance was higher, seasons started earlier and lasted longer than in 2004 and 2008, as a result of annual rainfall fluctuations. Differences in abundance for low and high disturbance sites decreased with years. Annual trends of generic richness resembled those detected for species. Likewise, similarity in genus and species composition decreased with time. Abundant and common taxa (13 genera and 18 species) were more persistent than rarer taxa being largely responsible for the annual fluctuations of the overall community. Numerous species were sporadic or newly introduced. The invasive species Anthidium oblongatum was first recorded in Niagara in 2006 and 2008. Previously detected seasonal variation patterns were confirmed. Furthermore, this study contributed to improve our knowledge of temporal dynamics of bee communities. Understanding temporal variation in bee communities is relevant to assessing impacts caused on their habitats by diverse disturbances.

Consistent with the governance shift towards network forms of governance, a number of new social movements have formed in response to the declining levels of physical activity in the Western world. One such movement is Active Canada 20/20: A Physical Activity Strategy and Change Agenda for Canada. Network governance is employed as the theoretical framework for this case study exploration of Active Canada 20/20 and the political landscape surrounding its development and implementation. Semi-structured interviews were conducted in addition to document/policy analysis and direct observations. Analysis of the data resulted in three overarching themes – the defining characteristics of network governance, the political landscape, and intersectoral linkages – that interconnect multifariously based the nature of the Canadian federal government and its relationship with the voluntary sector for physical activity. Despite progress in driving Active Canada 20/20 forward, entrenched dynamics of power need to be navigated within the political landscape surrounding network governance.

The Meat Packers Council of Canada was originally founded in 1919 in an effort to encourage farmers to produce better quality livestock. Originally known as the Industrial and Development Council of Canadian Meat Packers, charter members included Harris Abattoir Co. Ltd.; William Davies Co. Ltd.; Swift Canadian Co. Ltd.; Gunns Ltd.; Canadian Packing Co. Ltd.; Puddy’s Ltd.; F.W. Fearman Co.; Ingersol Packing Co. Ltd.; Whyte Packing Co. Ltd.; Gallagher-Holman & Lafrance Co. Ltd.; Gordon – Fronside and Fares Packers Ltd.; Wilson Canadian Co. Ltd.; and Armour & Co. Most of these firms were based in Ontario, but the Council’s operations were soon expanded with the opening of a western and eastern field office. The Council was incorporated in 1961. In 1980, the name changed to the Canadian Meat Council.

Pendant longtemps, l’assimilation a été la manière privilégiée par le gouvernement canadien pour intégrer les communautés autochtones à la société canadienne. Les pratiques des intervenants sociaux non-autochtones se situaient alors principalement dans cette idéologie et, par conséquent, ils ont contribué à opprimer les Autochtones. En raison de ces événements historiques, l’intervention sociale non-autochtone n’a pas très bonne réputation dans les communautés autochtones du Canada. En effet, bien que l’intervention sociale s’actualise dans le présent, elle est teintée d’une histoire et réinterprétée à partir des mémoires collectives et individuelles. Cette recherche s’inscrit alors dans une réflexion sur les fondements et la nature du travail social non-autochtone en milieu autochtone au Canada. L’objectif de ce mémoire est donc de comprendre comment des intervenants sociaux non-autochtones se perçoivent dans le contexte de leur pratique auprès des populations autochtones au Canada. Les données furent recueillies lors d’entrevues semi-dirigées réalisées auprès de onze intervenants sociaux allochtones pratiquant dans des contextes différents, mais tous auprès des Premières Nations ou Inuits au Canada. La théorie des représentations sociales nous a guidée dans l’analyse qualitative des données collectées. Au terme de cette recherche, nous avons constaté que les intervenants sociaux non-autochtones rencontrés ont des représentations assez critiques envers le travail social non-autochtone en milieu autochtone. Cela les amène à se percevoir différemment, voire plus positivement, par rapport à leurs perceptions de leur profession dans les contextes autochtones. Leur univers de représentations professionnelles influence donc le développement d’une pratique qui se situe en marge des approches occidentales dominantes actuelles.

Depuis quelques années, mais surtout depuis le 11 septembre 2001, les contrôles migratoires sont devenus le locus principal d’affirmation du pouvoir souverain dans les pays occidentaux. La mouvance sécuritaire actuelle semble avoir donné les outils conceptuels nécessaires aux États pour leur permettre d’amalgamer des notions autrefois distinctes, comme la sécurité et l’immigration, et d’en inférer des liens qui paraissent désormais naturels et évidents aux yeux du public. Le Canada s’inscrit aussi dans cette mouvance où l’immigrant et l’étranger sont désormais pensés en relation avec l’illégalité, la criminalité et le sujet de non-droit. En pratique, cela se traduit par la mise en œuvre étatique d’un pouvoir souverain qui se manifeste clairement et ouvertement dans le cadre de contrôles migratoires de plus en plus serrés et contraignants. Ainsi, alimenté par la justification sécuritaire, par l’affect de la peur et par la nécessité de combattre le terrorisme international, le Canada applique ses lois et ses politiques de manière à exercer un contrôle accru sur sa population, plus particulièrement sur les migrants en général, mais encore davantage sur les demandeurs d’asile et les réfugiés soupçonnés de terrorisme. La mise en œuvre de pratiques restrictives à l’endroit des demandeurs d’asile et des réfugiés est facilitée par une conviction très tenace. À la lumière de son comportement, le gouvernement canadien semble convaincu que l’exclusion, l’expulsion, voire le refoulement, à l’extérieur du territoire national des personnes jugées être de potentiels terroristes, permettront de renforcer la sécurité nationale. Cette conviction est elle-même supportée par une autre, à savoir la croyance selon laquelle le pouvoir souverain d’exclure quelqu’un du territoire est absolu et, qu’en situation d’exception, il ne peut être limité d’aucune manière par le droit international. Suivant ceci, la lutte antiterroriste s’exécute presque exclusivement par le rejet des éléments potentiellement dangereux à l’extérieur du pays, au détriment d’autres mesures moins attentatoires des droits et libertés, plus légitimes et plus à même de remplir les objectifs liés à la lutte au terrorisme international. Dans notre étude, par une relecture d’une décision paradigmatique de la Cour suprême du Canada, l’affaire Suresh, nous chercherons à ébranler ces convictions. Notre thèse est à l’effet que la prétention du Canada à vouloir en arriver à un monde plus sécuritaire, en excluant d’une protection internationale contre la torture et en refoulant de potentiels terroristes à l'extérieur de son territoire, constitue une entreprise vouée à l’échec allant potentiellement à l’encontre des objectifs de lutte au terrorisme et qui se réalise présentement dans le déni de ses obligations internationales relatives aux droits de l’Homme et à la lutte contre l’impunité. Généralement, à la lumière d’une analyse de certaines obligations du Canada dans ces domaines, notre étude révélera trois éléments, ceux-ci se trouvant en filigrane de toute notre réflexion. Premièrement, le pouvoir souverain du Canada d’exclure des individus de son territoire n’est pas absolu. Deuxièmement, le droit d’une personne à obtenir protection non plus n’est pas absolu et des mécanismes d’équilibrage existant en droit international permettent de protéger les personnes tout en s’assurant que le Canada ne devienne pas un refuge pour les terroristes potentiels. Troisièmement, le Canada est astreint à d’autres obligations internationales. Celles-ci protègent les personnes exclues d’une protection et forcent le gouvernement à lutter contre l’impunité.

En 2007, le premier ministre Stephen Harper a annoncé que le renouvellement de l’engagement du Canada dans les Amériques était une priorité internationale pour son gouvernement. Le document qui a formalisé la nouvelle priorité accordée à l’hémisphère occidental stipule que le Canada s’est engagé à faire progresser concurremment la démocratie, l’intégration économique et la sécurité. Cette recherche a pour but de remettre en cause le discours officiel en analysant la politique du Canada à l’égard de la Colombie et du Honduras. L’étude sur le cas colombien porte sur les effets de l’intégration économique sur les droits humains et la sécurité. Elle montre que le texte de l’accord de libre-échange Canada-Colombie et les évaluations d’impact sur les droits humains n’abordent pas convenablement les risques entourant les investissements canadiens et que leurs lacunes diluent l’engagement d’Ottawa envers la protection des droits humains et la résolution du conflit. L’étude sur le cas hondurien porte sur l’impact des déficits démocratiques et de l’insécurité sur l’intégration économique. Elle montre que le virage à droite qui a suivi le coup d’État de 2009 a permis au gouvernement canadien d’entreprendre des négociations de libre-échange bilatérales et de prendre part à la réforme du code minier du Honduras, tandis que les déficits démocratiques et l’insécurité ont empêché la population hondurienne de participer d’une manière significative au processus d’intégration économique. Nous concluons que ces deux cas contredisent le discours officiel dans la mesure où l’objectif de l’intégration économique a été atteint aux dépens des autres objectifs.

This paper approaches the topic of urban/community gardening not through the lens of urban theory per se but in light of basic farming realities such as growing season and land availability. Food security comprises availability and affordability. In the context of North American and Western European societies, only food affordability normally merits public discourse. In practice, governments have little or no means to change food affordability, in view of prevailing capitalistic free-market structures. In the current wave of popular exuberance, civic politicians and others have promoted the belief that community gardening could be the pathway to produce affordable food. The formidable obstacles to this pursuit include the availability of (low-cost) land within the highly-densified city limit, insufficient ambient temperature and water supply during the growing season and the contemporary structure of society. Overcoming these fundamental hurdles carries significant negative environmental and economic consequences.

Stable hydrogen isotopes (δD) in flight feathers were measured to investigate the summer origins of five species of boreal-breeding warblers captured during fall migration at Canadian Migration Monitoring Network (CMMN) stations spread across southern Canada. Mean δD varied among stations and species within stations, but there was broad overlap in δD values. Although isotope ratios indicate that migrants at each station come from a wide range of latitudes, they are unable to provide much longitudinal discrimination. Band recoveries are sparse, but indicate that in general western Canadian warblers move southeast in fall, eastern birds move southwest, and there is a transition zone in the Great Lakes region. Combining knowledge of migratory direction with isotope results increases discrimination of breeding areas. Isotope results support fall migratory movements by Blackpoll Warbler (Dendroica striata) and Northern Waterthrush (Seiurus novaboracensis) that are more easterly than for other species, and in all study species, birds from more northern regions passed through southern Canada later in the season. Migration monitoring stations capture birds from broad areas of latitude, and migrants passing through each province appear to come from largely different portions of the Canadian breeding range, so a few stations placed in each province should suffice collectively to sample birds from most of the boreal forest. Migration monitoring in southern Canada, therefore, has the potential to monitor status of boreal forest birds in Canada that are unsampled by other monitoring programs.

Livestock grazing in the shortgrass steppe of the Intermountain region of British Columbia is predicted to have significant effects on grassland habitats and their associated ground-nesting bird communities. We tested whether grazed and ungrazed sites could be discriminated on the basis of their vegetation communities, whether the abundance of two ground-nesting bird species, Vesper Sparrow (Pooecetes gramineus) and Western Meadowlark (Sturnella neglecta), differed between grazed and ungrazed sites, and whether vegetation variables found to differ between grazed and ungrazed plots could be used to predict the abundance of the two bird species at a fine scale. Grazed sites were easily distinguishable from a site that had been ungrazed for >30 years based on the structure and composition of their vegetation communities. However, more detailed grazing categories could not be distinguished on the basis of vegetation characteristics. Despite the existence of grazing effects on vegetation structure and composition, we found no consistent differences in abundance of Vesper Sparrows and Western Meadowlarks between the grazed and ungrazed sites. However, there was weak evidence that the abundance of both species was higher at fine-scale plots (100 m radius point count station) with less bare ground and taller vegetation. Bare ground cover was lower on grazed plots, but vegetation was taller on ungrazed plots. Combined, our results suggest that low intensity grazing leads to grassland habitat change with both negative and positive effects on Vesper Sparrows and Western Meadowlarks, resulting in no net change in their broad-scale abundance.

A high-resolution record of sea-level change spanning the past 1000 years is derived from foraminiferal and chronological analyses of a 2m thick salt-marsh peat sequence at Chezzetcook, Nova Scotia, Canada. Former mean tide level positions are reconstructed with a precision of +/- 0.055 in using a transfer function derived from distributions of modern salt-marsh foraminifera. Our age model for the core section older than 300 years is based on 19 AMS C-14 ages and takes into account the individual probability distributions of calibrated radiocarbon ages. The past 300 years is dated by pollen and the isotopes Pb-206, Pb-207, Pb-210, Cs-137 and Am-241. Between AD 1000 and AD 1800, relative sea level rose at a mean rate of 17cm per century. Apparent pre-industrial rises of sea level dated at AD 1500-1550 and AD 1700-1800 cannot be clearly distinguished when radiocarbon age errors are taken into account. Furthermore, they may be an artefact of fluctuations in atmospheric C-14 production. In the 19th century sea level rose at a mean rate of 1.6mm/yr. Between AD 1900 and AD 1920, sea-level rise accelerated to the modern mean rate of 3.2mm/yr. This acceleration corresponds in time with global temperature rise and may therefore be associated with recent global warming. (c) 2005 Elsevier Ltd. All rights reserved.

Stenophragma Skuse was originally described for S. meridianum (Skuse), from Australia. Since then seventeen species have been added to the genus-from Brazil, Ecuador, Peru, Bolivia, Paraguay, Chile, Argentina, and Canada. We add two new species to the genus Stenophragma-S. bickeli n.sp. and S. collessi n.sp.-from Western Australia. An identification key for the Australian species of Stenophragma is provided. Comments are made about possible relationships among these new species and the remaining Australasian species of the genus. OLIVEIRA, SARAH SIQUEIRA, AND DALTON DE SOUZA AMORIM. 2012. Two new species of Stenophragma Skuse from Western Australia (Diptera, Mycetophilidae, Sciophilinae). Records of the Australian Museum 64(2): 149-158.
