To come and go : transnational life between Mexico and Alaska

This dissertation examines the experiences of place and patterns of transnational mobility of three generations of people who have been living between Acuitzio del Canje, Michoacán, Mexico and Anchorage, Alaska, USA for several decades. These people hold dual US-Mexican citizenship or US permanent residency and are able to move across the continent in a way that many Mexican migrants cannot. Based on twelve months of ethnographic research in both Acuitzio and Anchorage, and ten years of engagement with people in these locations, I analyze the experience of Acuitzences (people from Acuitzio) at several levels: as they encounter frictions in their movements between Michoacán and Alaska; the practices of multigenerational family units who gain traction over time to build lives in both Anchorage and Acuitzio; the uneven and situated habits that generate a transnational class formation, and the ways in which Mexicans in Alaska re-conceptualize their senses of place by developing transnational identities out of the symbols and mechanisms of both nation-states. In showing how distance is key to the experience of Mexican migrant-immigrants in Alaska, this research also contributes to theorizations of the relevance of distance in the creation of spatialized differences. My analysis reveals that over time, Acuitzences in Alaska orient their lives to both locations as they live, work, and imagine their futures across the continent. Acuitzences in Alaska have created a transnational social field and orient themselves more to the field as a whole than to any one location in it. For most of them, Acuitzio, Anchorage, and the experience of mobility between the two places are necessary to feel at home in the world. These findings contribute to the anthropological research on mobility, citizenship, transnational migration, and the production of space, and bring the spatially bounded fields of Circumpolar Studies and Latin American Studies together. Based on this, I advocate for a transnational approach to theory and policy that embraces the multiple trajectories that construct places. Despite policy restrictions to migration, the lives of transnational Acuitzences who come and go show how the United States and Mexico are profoundly coproduced geographies.Arts, Faculty ofAnthropology, Department ofGraduat

Reconnecting Alaska: Mexican Movements and the Last Frontier

This paper discusses the initial findings of on-going research with Mexican migrants and immigrants to Alaska. The paper outlines the historical and on-going connections between Alaska and Mexico and explores how and why those connections have been obscured or ignored. Powerful imaginaries are associated with places: Alaska, and 'the north' more generally, and Latin America, and Mexico specifically. My research shows how interesting things happen when they are brought together through movement. People from Acuitzio del Canje, Michoacán began travelling to Alaska (Anchorage, and elsewhere) to work in the 1950s, and movement between Mexico and Alaska has continued across generations since then. Today, many Acuitzences who live in Anchorage maintain a close relationship with friends and family members in Acuitzio, and travel back and forth regularly. However, this movement is obscured by ideological work that makes Alaska seem separate, isolated, wild, and a place where Mexicans are not imagined to be. Mexican movements into Alaska over time disrupt this vision, showing how Alaska is connected to multiple other geographies, and making the US-Mexico border a salient reference point in everyday life in Anchorage. When the South moves into the North, it can make us think about both 'Alaska' and 'Mexico' in different ways. When the US-Mexico border is relocated to Anchorage, if only for a moment, it can elicit a reaction of humour or surprise. Why is that? And what does this have to do with how people actually live in an interconnected place

Chronic exposure to volcanic environments and cancer incidence in the Azores, Portugal

Whether volcanic environments pose a risk in cancer incidence is unknown. We investigated this question in two populations, one from an area with active manifestations of volcanism (Furnas) and another from an area without volcanic activity since 3 million years ago (Santa Maria), both in Azores. Incidence data on cancer among the populations of Furnas and Santa Maria during 1991-2001 were obtained from medical records of local health centers. Age-standardized rates and relative risks were estimated. Overall incidence rates were higher in the volcanically active area when observing all cancers and both sexes combined. However, the non-volcanically active area presented higher rates of cancer of digestive, respiratory and intrathoracic organs, mainly in males, while the area with volcanic manifestations showed higher rates of cancer of lip, oral cavity and pharynx, in both sexes, and female breast. Relative risk estimates between both populations suggest a higher risk for cancer in some groups of organs in Furnas, especially of lip, oral cavity and pharynx cancer, and breast, that may be partially explained by the chronic exposure to environmental factors resulting from volcanic activity, such as hazardous gases and aerosols, much of them associated to trace metals.http://www.sciencedirect.com/science/article/B6V78-4JG49W6-1/1/c5e8ce88f9a1cc50a5d4a04a44377ba

A Simple Tiered Methodology for the Determination of Ambient Air Quality Guidelines

peer reviewedWithin the scope of the renewal of industrial operating permits in Belgium, the Walloon Agency for Air and Climate needed air quality criteria for a wide range of toxics. Due to the plethora of different existing values for some compounds or the total lack for others, the development of a simple methodology was required to provide both quality and intervention criteria, corresponding respectively to a chemical concentration for which no adverse health effects are expected for a lifetime exposure, and the chemical concentration in air associated with a risk for human health deemed significant. The tiered methodology developed here allows the selection of air guidelines from available databases, and proposes, if needed, approaches based on well-proven procedures to derive air quality guidelines from occupational exposure limits, drinking water guidelines, tolerable daily intakes, or as a last resort acute lethal toxicity data if nothing else is available. If this method has been successfully applied to more than 550 compounds, all values produced should be validated according to the purpose of the guidelines, the technical feasibility of achieving the threshold produced, and the specificity of the environment conditions and the targeted population. Moreover, the criteria obtained from non-air-related data should be critically examined and handled with caution
