The border floods,August 1956

The dominance of Mexico City over the remainder of the country appears to offer conclusive evidence that Mexico's space economy is characterised by core‐periphery relationships. Most measurable criteria indicate that the Yucatan peninsula is part of the periphery. Despite this, it is possible to argue that within the Yucatan peninsula* itself, the city of Merida acts as a core area and has been responsible for a considerable degree of autonomous economic growth, thus acting as a core within the periphery.     

Metropolis on the margins: talent attraction and retention to the St. John's city‐region

The objective of this research is to examine the factors that influence the attraction and retention of creative and highly educated workers in a small‐sized Canadian city. The study examines two hypotheses: that the social dynamics of city‐regions constitute the foundations of economic success in the global economy; and, that talented, highly educated individuals will be attracted to those city‐regions that offer a richness of employment opportunity, a high quality of life, a critical mass of cultural activity and social diversity. The hypotheses are explored through in‐depth interviews with creative and highly educated workers, employers and intermediary organizations. The evidence from the interviews suggests mixed support for the hypotheses. In view of these findings, we contend that the specificities of place must be more carefully theorized in the creative class literature and be more carefully considered by policy‐makers designing policies directed towards attracting and retaining talented and highly educated workers.     

A boat perspective: local geographic knowledge of fish harvesters in Change Islands,Newfoundland

People whose livelihoods depend on the natural environment have detailed knowledge of the lands and waters surrounding their communities. This paper presents research on the traditional geographic knowledge of fish harvesters in Change Islands, Newfoundland. Our findings, based on “kitchen table mapping” and other ethnographic methods, demonstrate that residents of coastal communities have extensive geographic knowledge associated with a way of life centred on fishing. This knowledge is reflected in a “namescape” that includes hundreds of toponyms that are not present on existing maps and that reflect meaningful connections with local history and cultural heritage. Fish harvesters also have distinctive ways of conceptualizing the landscape and the seascape, which is reflected in the geographic terminology they use. Overall, their way of looking at the environment, in contrast to the bird's-eye perspective that prevails in western cartography, can be characterized as a “boat perspective”. Their geographic knowledge has practical value for improving existing cartographic information and developing sustainable resource use strategies. At a broader level, their distinctive ways of interpreting the “earthscape” provide alternative ways of understanding space and place, and can help us identify our assumptions about how we define geographic features and represent them on maps.     

Party Policy Positions in Newfoundland and Labrador: Expert Survey Results in the Buildup to the 2011 Provincial Election

In this article, we present the estimates of the party policy positions derived from two surveys: an expert survey and a voter survey, which were conducted in the Canadian province of Newfoundland and Labrador immediately prior to the October 2011 provincial election. The experts and the sample of voters were asked to situate the major political parties on eight policy dimensions and to rank the importance of each policy area. The results of the study present not only a map of party policy space and voter preference in Newfoundland and Labrador but also an indication of party policy awareness in the province.     

The Churchill–Roosevelt Bases of 1940: The Question of Heritage in their Adaptive Reuse

The US military bases in the British Western Atlantic colonies, negotiated between Churchill and Roosevelt and formalised in the 1941 Destroyers–Bases Agreement, were all abandoned by the 1990s. In the process of their reuse the question of heritage meanings arises. From existing thoughts on heritage in older military bases, the paper considers the legitimacy of recent (living memory) bases as heritage, by reference to various cases among which Malta is particularly persuasive. The Churchill–Roosevelt bases and their heritage potential are then reviewed. The paper examines the three principal naval/military bases involved, namely Argentia (Newfoundland), Bermuda and Chaguaramas (Trinidad), with respect to what heritage perspectives exist among redevelopment agencies and other concerned institutional actors. In all cases heritage constitutes a recessive if not contentious issue among the priorities of base reuse in now post‐colonial environments.     

Fluids associated with hydrothermal dolomitization in St. George Group,western Newfoundland,Canada

Dolomite reservoirs are increasingly recognized as an important petroleum exploration target, although the application of a hydrothermal dolomite exploration model to these reservoirs remains controversial. The St. George Group of western Newfoundland consists of a sequence of dolomitised carbonates, with significant porosity development (up to 30%) and petroleum accumulations. Fluid inclusion microthermometry and bulk fluid leach analyses indicated that fluids responsible for matrix dolomitization (associated with intercrystalline porosity) and later saddle dolomitization are CaCl₂ ± MgCl₂ rich, high salinity (up to 26 eq. wt% NaCl) brines. Integration of fluid inclusion data with thermal maturation histories from the St. George Group show that these dolomites formed at temperatures higher than the ambient rock temperature, and are therefore hydrothermal in origin. Bulk leach analyses show that dolomitization is associated with influxes of postevaporitic brines (±Cl enriched magmatic fluids) late in the diagenetic history of these carbonates. This dolomitization is possibly Devonian in age, during a period of significant magmatic activity, extensional tectonics and development of hypersaline basins. Petrographic and geochemical similarities between Paleozoic hosted hydrothermal dolomitization in western Newfoundland, eastern Canada and the northeastern United States are consistent with a regional‐scale hydrothermal dolomitization event late in the diagenetic history of these carbonates.
