A century and counting: Geographical research on Guatemala in historical perspective

In his recent book Putting Science in its Place: Geographies of Scientific Knowledge (2004), David Livingstone challenges historians of geography to locate that history in space and places, as well as time. Using the national/cultural space that is Guatemala, this paper plots some of the co-ordinates, contours, and questions that such a geographic history might entail. Particular emphasis is placed on providing a first approximation of the contours the history of geographic research in, and on, Guatemala. The main focus is on the work of self-identified geographers, though many scholars in cognate fields, especially historians, archaeologists, and anthropologists have made important contributions to this history. Clear phases in this history are evident, starting in the late 19th century with the work of the German geographer Karl Sapper. North American geographers came to dominate the record in the post-WWII period. The current phase promises not only a new generation of researchers, but also new directions as well as some continuities with topics and questions with a century-old time-depth. This paper seeks to contribute to the largely inchoate project of producing histories of geography at the regional, national, and continental scales for Latin America.     

The politics of identity: Ethnicity, minority and nationalism in Soviet Estonia

Identity has become one of the core concepts of political geography. This reflects the wide recognition of a post-structural conception of society and space, as well as the acknowledgement of the political character of identity. The present article focuses on the politics of identity, and discusses the politicized forms of identity as related to the Soviet state building policies and the Estonian spaces of resistance. It will be argued that neither identity nor the political demand in Soviet Estonia can be viewed in isolation from their historical and social contexts. Both Soviet state politics and the Estonian spaces of resistance reflected the prevailing conceptions of past and the contemporary political realities. This article examines those preconceptions of the political and territorial development in Soviet Estonia, and also illustrates the interdependent character of state politics and non-state activism. The first part of the article concentrates on the Soviet state building practices – the use of power, symbols, education – and the second part examines the various forms of non-state activism of Estonians.     

Assessment of lightning-related fatality and injury risk in Canada

This article summarizes research completed to assess the risk of lightning-related injuries and fatalities in Canada. Although lightning mortality has declined significantly over the past century, it remains a common meteorological hazard that regularly kills and injures. Based on an analysis of media reports, vital statistics, hospital admission and emergency room visit records, and fire loss data, the authors estimate that on average about 9–10 lightning-related deaths and 92–164 injuries occur each year in Canada. The distribution of casualties reflects current provincial population and cloud-to-ground lightning densities. Consistent with similar studies in other developed nations, most lightning-related fatalities and injuries in Canada occur during the June-August summer season, coincident with peak lightning, and during the Thursday-Saturday period, most likely related to higher rates of participation in outdoor activities. The majority of victims are male, less than 46 years old, and engaged in outdoor recreational activities when injured or killed in a lightning incident. Media reports used in the study were found to underestimate both lightning mortality (36%) and morbidity (20–600%).

Transnationalism-integration nexus: Examining the relationship between transnational housing investment and homeownership status in Canada

The housing outcomes of immigrants in Canada vary mainly along ethnicity. However, many other factors including place of birth, length of stay in Canada, labour market outcomes, and discrimination among others also play a role. Although general patterns are observable at broad ethnic group levels, vast intra-group differences exist—with housing outcomes potentially being influenced by specific group behaviours such as transnational (housing) activities. This study investigates the relationship between homeownership in Canada and Ghanaian immigrant transnational housing investment. Logistic regression models are fitted on survey data collected among Ghanaian immigrants resident in the Greater Toronto Area. The results show an association between homeownership status in Canada and transnational housing investment. Interestingly, we found that immigrants with on-going housing projects in Ghana were more likely to own a house in Canada. Theoretically the findings demonstrate the importance of including a transnational perspective in immigrant housing integration research. The findings show that it is possible to simultaneously engage in transnational activities and remain integrated in the society of destination areas. This has wider implications for the transnationalism-integration debate within immigrant receiving nations across the world. Recognition of transnationalism as a possible conduit for enhancing integration in destination societies should result in eschewing alarmist perspectives which have been relied on to formulate anti-immigration policies.     

Boundaries and transborder relations,or the hole in the prison wall: On the necessity of superfluous limits and boundaries

Boundaries can be seen as barriers or as places of contact. It has been suggested that we are “prisoners of borders”, of all kinds of borders (political, religious, social, cultural, linguistic etc.). While this statement appears to be somewhat exaggerated, it holds some truth. Boundaries are elements in spatial organization, and they influence daily life in many ways (not only for people living right along them). The paper addresses the question if we must call ourselves “prisoners” or if we simply have to live with all kinds of borders. Departing from theoretical observations, the paper discusses the various aspects boundaries assume in the European context before looking at a few concrete Swiss examples. They reveal that even regions at a certain distance of the state border will feel its effects (the case of Zurich airport), but the most important benefit can been drawn by people living in the border area itself (through price differences between the two countries, as exemplified by the Swiss-Italian border). There may be asymmetry on state borders, but this asymmetry can also swing around: the advantages often lie on both sides. The paper concludes by pointing to the persistence of the boundary concept. They are a necessity for the organization of space and society, but they are not absolute. There are always holes in these prison walls, and the examples where boundaries were impermeable are probably rare.     

The political geography of religion: historical state-church relations in Europe and recent challenges

Historical processes of state formation and nation building are crucial for an understanding of the geography of religions and churches in Europe. Each country has developed its own model of state-church relations, giving rise to a ‘bewildering variety’ as Grace Davie aptly remarks. The aim of this paper is to bring some order to this variety by developing a framework for the comparative study of church-state relations based on Stein Rokkan’s famous conceptual map and recent extensions of it to Central and Eastern Europe by John Madeley. According to that framework Europe has been divided into three mono-confessional (Roman Catholic, Lutheran, and Eastern Orthodox) blocs and two multi-confessional culture belts from Northwest to Southeast, and from Northeast to Southeast. This historical pattern has been challenged by secularisation, which started with the Enlightenment and the French Revolution (Western Europe) and the Russian Revolution (Eastern Europe until the velvet revolutions of 1989/1991) and then became widespread after the ‘cultural revolutions’ of the 1960s. A second challenge has to do with globalisation and its consequences, such as massive immigration and the rise of immigrant religions, and in general deterritorialisation, which means the disembeddedness of religion from its national territory. A third challenge concerns reterritorialisation at other (supranational, regional, transnational, and local) scales, of which the new territorial order of the European Union seems to be the most important. Finally, this paper serves as an introduction to the case studies on church-state relations in this special issue.     

The interplay between social welfare and competitiveness: The case of Canadian Medicare

Canadian Medicare, the government financed national health care system, is seen by many as enhancing both social welfare and competitiveness. If true, this will broaden and further existing conceptions of competitiveness in Canada and beyond. Moreover, it will have important implications for the ongoing debate in the social sciences about institutional convergence and path dependence. The central focus of this paper is to evaluate this claim: Medicare’s impact on competitiveness, evaluated by using investment attraction as a proxy, is determined through reference to detailed case analysis and the insight into investment behavior gained from interviews. This paper concludes that Medicare makes a difference for certain reinvestment decisions but no difference for location and initial investment decisions. Several implications are drawn from this finding: Medicare’s impact on reinvestment decisions may stop certain Canadian firms from investing elsewhere but likely would not attract new investment into Canada from abroad. Industries with high labor costs will extract a disproportionately large benefit from Medicare; so, this type of institution is a source of competitiveness to certain industries if not an overarching source of regional competitiveness for Canada. I conclude that, no matter the size and scope of the competitive benefit, social institutions such as Medicare must be considered when evaluating regional competitiveness, having thus far been ignored by mainstream academic competitiveness theories.     

Heat Wave Hazards: An Overview of Heat Wave Impacts in Canada

Extreme heat events are natural hazards affecting Canada and many other regions of the world. This paper presents an overview of the issues involved in defining heat waves and harmful hot weather events, followed by a spatial and historical overview of heat waves across Canada, and an assessment of heat wave adaptation potential in selected cities. The Prairies, Southern Ontario, and areas in the St. Lawrence River Valley of both Ontario and Quebec demonstrate the highest temperatures and most frequent occurrences of heat waves, with minimal effects in the North, Pacific Coast, and Maritimes. Montreal frequently experiences extreme heat, and based on its low air conditioning rates and older, high-density housing, it demonstrates limited potential for adaptation to heat events. A scientific assessment was done to identify the effects of heat waves on various sectors of Canadian life including agriculture, livestock, fisheries, construction, transportation, utilities, the environment, and human health. Heat stress has been linked to excess human mortality and illness, violent behaviour, drought, forest fires, tornadoes, decreased agricultural and livestock productivity, construction and transportation difficulties, and reduced electrical power supply. Despite limited research on heat waves in Canada, this study demonstrates that the impacts of heat are profound and far-reaching.

The view from out West: embeddedness, inter-personal relations and the development of an indigenous film industry in Vancouver

This paper considers the development of a particular cultural industry, the indigenous film and television production sector, in a specific locality, Vancouver (British Columbia, Canada). Vancouver’s film and television industry exhibits a high level of dependency on the location shooting of US funded productions, a relatively mobile form of foreign investment capital. As such, the development of locally developed and funded projects is crucial to the long-term sustainability of the industry. The key facilitators of growth in the indigenous sector are a small group of independent producers that are attempting to develop their own projects within a whole series of constraints apparently operating at the local, national and international levels. At the international level, they are situated within a North American cultural industry where the funding, production, distribution and exhibition of projects is dominated by US multinationals. At the national level, both government funding schemes and broadcaster purchasing patterns favour the larger production companies of central Canada. At the local level, producers have to compete with the demands of US productions for crew, locations and equipment. I frame my analysis within notions of the embeddedness or embodiment of social and economic relations, and suggest that the material realities of processes operating at the three inter-linked scales, are effectively embodied in a small group of individual producers and their inter-personal networks.     

Tectonic and eustatic control on deposition and preservation of Upper Cretaceous ooidal ironstone and associated facies: Peace River Arch area, NW Alberta, Canada

The Late Coniacian, shallow-marine Bad Heart Formation of the Western Canada foreland basin is very unusual in that it contains economically significant ooidal ironstone. Deposition of shallow-water and iron-rich facies appears to have been localized over the crest and flanks of a subtle intrabasinal arch, in part interpreted as a forebulge and partly attributed to reactivation of the long-lived Peace River Arch. The formation comprises two upward-shoaling allomembers, typically 5–10 m thick, that are bounded by regionally mappable ravinement surfaces. The lower unit, allomember 1, grades up from laminated mudstone to bioturbated silty sandstone, which is abruptly overlain by bioturbated ooidal silty sandstone grading into an almost clastic-free ooidal ironstone up to 7 m thick. Ooidal ironstone was concentrated into NW- to SE-trending ridges, kilometres wide and tens of kilometres long. Ironstone formation appears to have been promoted by: (a) drowning of the arch, which progressively curtailed sediment supply; and (b) enhanced reworking over the shallowly submerged arch and over a fault-bounded block that underwent episodic vertical movement of 10–20 m during Bad Heart deposition. Allomember 2 also shoals upwards from mudstone to bioturbated and laminated silty sandstone but lacks ooids, apparently reflecting a rejuvenated supply of detrital sediment from the arch. The marine ravinement surface above allomember 2 is a Skolithos firmground, above which is developed a regional blanket of ooidal sediment. In the east, ooids are dispersed in a bioturbated silty sandstone with abundant evidence of repeated reworking and early siderite and phosphate cements. Westwards, this facies grades, over about 40 km, into almost clastic-free ooidal ironstone about 5 m thick; the lateral facies change may reflect progressive clastic starvation distal to a low-relief source area. The two allomembers are interpreted to reflect eustatic oscillations of about 10 m, superimposed on episodic tectonic warping and block-faulting events. The development of ooidal ironstone immediately above initial marine flooding surfaces indicates a close relationship to marine transgression, reflecting sediment-starved conditions. Ironstone does not appear to be related to either sequence boundaries or maximum flooding surfaces. The Bad Heart Formation is blanketed by marine mudstone deposited in response to major flexural subsidence and rejuvenation of clastic sources in the Cordillera to the SW.

Multi-level governance of climate change adaptation through regional partnerships in Canada and England

Adaptation to climate change is widely recognized as a multi-level governance challenge because expected impacts and respective measures cut across governmental levels, sectors and societal domains. The present paper analyses the role of regional adaptation partnerships in Canada and England in the multi-level governance of climate change adaptation. We describe and compare three partnerships per country with regard to their evolution, membership and governing structures, coordination across levels and societal domains, and their adaptation activities and outputs. Although both partnership schemes represent new collaborative approaches, their genesis and governance differ. While the Canadian collaboratives are a government-centred approach that originated and partly operated top-down through a national programme for the period 2009–2012, the English partnerships follow a more pluralistic stakeholder-centred approach that evolved bottom-up already in the early 2000s. Both schemes have in common that they mediate between governmental levels, foster networking between public and private actors, and eventually build adaptive capacities and inform adaptation policies. We conclude that regional adaptation partnerships represent a new governance approach that facilitates climate change adaptation, albeit with limits. Since state actors play(ed) key roles in both partnership schemes, they do not represent a new sphere of authority outside the state. Instead of blurring or destabilizing governmental levels they complement (and perhaps even stabilise) them with multi-level interactions.     

Risky bodies: Public health, social marketing and the governance of obesity

The inclusion of obesity within public health rests on a proven and accepted biomedical link between body weight and health status. Drawing on the 2005 controversy over annual death rates attributable to obesity in the US, this paper contends that uncertainty as to the causal mechanisms linking body weight and health are undermining the development of effective obesity prevention policies. Consequently, this also weakens the justification of the inclusion of such policies within public health. This work draws on recent interest in ‘critical geographies of public health’ and the continued attention to the recursive relations between people and places in the context of health which may offer a useful theoretical viewpoint from which unpack such aetiological uncertainty. Without an agreed or universal risk from obesity, the paper argues that public health obesity prevention through social marketing should be geographical in outlook. The three examples of 5 a day, Jamie’s School Dinners and Sesame Street’s Cookie Monster are discussed to illustrate the effectiveness of communicating risk in a manner that allows intention to be effectively translated into risk-minimising behaviour within the dictates of locale.

Hydrocarbons and water in the Western Canada Sedimentary Basin — A tale of two fluids

Detailed petroleum system analysis allows the direction and extent of hydrocarbon flow to be assessed. In most parts of the Western Canada Sedimentary Basin, the major pulse of hydrocarbon generation and migration occurred as a result of the Laramide Orogeny in Late Cretaceous–Early Tertiary time. The distribution and chemistry of oils provide a detailed picture of fluid flow at this time with oil migration up to hundreds of kilometres observed. Hydrocarbon generation and migration mostly ceased once uplift of the basin commenced during Eocene time. As the basin evolved so did the hydrodynamic regime reflecting changes in topography, glaciation and other factors. This indicates possible problems with using present day hydrogeology to determine oil migration pathways although hydrogeology can help explain petroleum alteration.     

Temporal analysis of groundwater nitrate concentrations from wells in Prince Edward Island,Canada: application of a linear mixed effects model

Changes in nitrate concentration in groundwater from wells in Prince Edward Island, Canada were investigated over time using two datasets. Temporal trends in groundwater nitrate concentrations were assessed annually during 1981–1996 (1,299 observations), and both seasonally and monthly during 1988–1991 (1,868 observations). Data were analysed using linear mixed models with random effects and correlation structures. The average nitrate concentration in the monthly dataset was 3.99 mg/L as NO₃–N, with January, May, and November concentrations being higher (p?=?0.018). A seasonal effect was present when season was combined with land use type in an interaction term (p?=?0.004). Wells located in agricultural areas had greater nitrate concentrations than urban areas, which in turn, had greater values than low human-impact areas. Row-cropped areas had higher groundwater nitrate concentrations in the summer, whereas manure storage areas were higher in the spring and autumn. Nitrate in groundwater in areas with low human impact and with centralized sewage disposal infrastructure remained relatively low and stable throughout the seasons. There was no significant annual trend (p?=?0.954), but for individual sites, 9.6% significantly increased in nitrate concentration over time, and 6.6% significantly decreased over time.     

An Assessment of Changes in Winter Cold and Warm Spells over Canada

The recent Third Assessment Report (TAR) of the Intergovernmental Panel onClimate Change (IPCC) indicated that observed 20th century changes in severalclimatic extremes are qualitatively consistent with those expected due to increasedgreenhouse gases. However, a lack of adequate data and analyses make conclusiveevidence of changing extremes somewhat difficult, particularly, in a global sense.In Canada, extreme temperature events, especially those during winter, can havemany adverse environmental and economic impacts. In light of the aforementionedIPCC report, the main focus of this analysis is to examine observed trends andvariability in the frequency, duration, and intensity of winter (Jan–Feb–Mar) cold and warm spells over Canada during the second half of the 20th century.Cold spell trends display substantial spatial variability across the country. From1950–1998, western Canada has experienced decreases in the frequency, duration, and intensity of cold spells, while in the east, distinct increases in the frequency and duration have occurred. These increases are likely associated with morefrequent occurrences of the positive phase of the North Atlantic Oscillation (NAO)during the last several decades. With regard to winter warm spells, significantincreases in both the frequency and duration of these episodes were observedacross most of Canada. One exception was found in the extreme northeasternregions, where warm spells are becoming shorter and less frequent. The resultsof this study are discussed within the context of climate warming expectations.
