The aim of this study was first to assess the relevance of a marine sponge, Spongia officinalis, as a biomonitor of PCB. Twenty-four chlorobiphenyl congeners have been measured along a pollution gradient both in sponges and seawater. S. officinalis displays a capacity to accumulate all types of congeners. The highest concentration factors were found for hexa-and heptachlorobiphenyls. Concentrations recorded in sponges agreed quite well with the PCB concentrations of study sites. The prevalence of CB138 and CB153 definitely demonstrated the urban origin of the PCB detected, despite the ban on their production and the existence of a wastewater treatment plant since 1987. The CB138/CB153 ratio is ∼1.2 in commercial mixtures as well as in seawater. In sponges, this ratio varies strongly in space and time, from 1 in sponges at the most polluted site to 0.3 at the reference site. This change in the ratio of these two very persistent congeners, which is not observed in seawater, indicates a metabolism of CB138 in sponges. As it was recently demonstrated for nonpersistent organic contaminants, sponges might well be able to degrade PCB, but further work is needed to identify the processes involved. * Corresponding author phone: 33 4 91 04 16 26; fax: 33 4 91 04 16 35;

T he field of ar.chitectural history in Canada has traditionally been underpinned by a nationalist model that has related the built environment to notions of collective, universa l, and human identity. Over the p ast century, little has been w ritten to cha llenge this ultimately Eurocentric paradigm of granting citizenship to buildings. Wha t unites some of these attempts at constructing so-called Canadian histories through architecture is the use of shifters, or deictics, words that are "understandable only from the perspective of the speaker, and thus [shift] from speaker to speaker in ways that are comprehensible in spoken, faceto-face conversation but often become ambiguous over the telephone or in formal writing."' In this p aper, I focus on the pronouns "we" and "our" as shifters employed by authors in Canada, whose works, as a result of this grammatical usage, culminate in an "ambiguous" portrayal of a p articular situa tion.

Since 1993, the Canadian government has used biometric screening to identify migrants crossing in and out of Canadian territory. Recently, however, the government has sought to enhance the scope of biometric screening through a number of proposed acts and programs. Of particular interest is the 2013 Temporary Resident Biometrics Project. The Project will require that foreign nationals provide enhanced biometric details, including fingerprints and facial capture, which will be shared with other governmental departments such as the Royal Canadian Mounted Police and Canada Border Services Agency. Although the Canadian government has made reference to increasing vulnerabilities in their capacities of identification and verification, it is unclear exactly why the enhanced surveillance and governance of noncitizens is necessary. We argue that the increasing deployment of biometrics is part of a larger global program designed to promote and manage temporary, short-term labor. We explore this use of biometrics by contextualizing the arguments advanced by the Temporary Resident Biometrics Project within the larger neoliberal discourse of market uncertainty and risk management. The working theory draws from Callon's thesis of hybrid forums to investigate the economization of biometric screening and, in turn, how the state's relationship and obligations to noncitizens are increasingly defined through the rhetoric of a market-driven economized service. A brief overview of the Canada–U.S. NEXUS program serves to demonstrate the Project's relevance to understanding how surveillance is being used to manage global flows of labor.

In 2020, migrant farmworkers in Canada, cast as essential to sustaining the national food supply, experienced relatively high COVID-19 infection rates. Taking Southern Ontario as its focus, this article reveals how the federal government response to COVID-19 in agriculture perpetuated the effects of longstanding laws and policies requiring migrant farmworkers, circumscribed in their ability to politically mobilize on account of their institutionalized deportability, to shoulder disproportionate amounts of economic, social, and health risks. Centering the transnational character of migrant farmworkers' renewal, it identifies meaningful interventions to limit the structural disempowerment of migrant farmworkers and the externalization of their social reproduction.

Compres~on fossils of a new plant, Anapaul~ moodyi Berry et Edward~ gen. et sp. no~, are described ~om the Middle or Upper Devonian of western Venezud~ The m~n novel characteristic of this plant ~ that the monopodi~ m~n ax~ has both large second-order axes as we~ as smaller dichotomi~ng branches inse~ed in a predominantly whorled arrangemenL the whorls bong separated by long internodes. Third-order axes and small fourth-order axes are borne in compre~ed helices and he~ce~ Small ultimate branching sy~em~ which dichotomize up to four times, are borne on the third-and fou~h-order axes in helices and compressed helices. Ellipt~al sporangia are borne upon the recurved tips of ultimate branching sy~ems otherwise similar to the sterile examples.

Acculturation and Nutritional Health of Immigrants in Canada: A Scoping Review
Journal of Immigrant and Minority Health, 2013
Although recent immigrants to Canada are healthier than Canadian born (i.e., the Healthy Immigrant Effect), they experience a deterioration in their health status which is partly due to transitions in dietary habits. Since pathways to these transitions are under-documented, this scoping review aims to identify knowledge gaps and research priorities related to immigrant nutritional health. A total of 49 articles were retrieved and reviewed using electronic databases and a stakeholder consultation was undertaken to consolidate findings. Overall, research tends to confirm the Healthy Immigrant Effect and suggests that significant knowledge gaps in nutritional health persist, thereby creating a barrier to the advancement of health promotion and the achievement of maximum health equity. Five research priorities were identified including (1) risks and benefits associated with traditional/ethnic foods; (2) access and outreach to immigrants; (3) mechanisms and coping strategies for food security; (4) mechanisms of food choice in immigrant families; and (5) health promotion strategies that work for immigrant populations.
