Urban Form,Sustainability and Health: The Case of Greater Oslo

Several studies have shown dense urban structures to be favourable in order to reduce greenhouse gas emissions from transport, limit energy consumption in buildings and protect farmland and natural areas in the surroundings of the city. There may, however, be some tensions between such a compact urban developmental strategy and considerations of public health in urban planning. This paper reviews findings from international research on the relationships between urban form and health and illustrates some of these effects by comparing statistics on life expectancy and the frequency of heart attacks among inhabitants of different urban districts in the Norwegian capital Oslo. Since we have only had access to aggregate figures at the level of urban districts, the results must be interpreted with caution. The currently available results do, however, suggest that the densification strategies often recommended for reducing the ecological footprints of cities might be encumbered with some important drawbacks, seen from a public health perspective. Based on the findings, some dilemmas and perspectives for sustainability- and health-oriented urban planning are discussed.     

Exploring a Strategic Turn: Case Study of Innovation and Organizational Change in a Productivist Dairy

Some firms within the conventional agri-food processing industry change their business strategy by trying to innovate towards alternative foods, like regional foods. For firms which are part of a larger organization or integrated in a group of companies this is a special challenge. The purpose of this paper is to explore what happens when a firm within a large and complex organization tries to turn from a productivist strategy to a differentiated strategy. This exploration uses a case study from the Norwegian dairy industry. The case shows that powerful industrial conventions and lack of suitable organizational conditions can be a hindrance for organizational change. Organizational capabilities to change routines and conventions have significant influence on the result of the innovation process.     

Shared rivers and conflict – A reconsideration

Neomalthusians have regularly predicted "water wars" while cornucopians have argued that there is no inherent water scarcity and liberal institutionalists have seen cooperation as a more likely outcome of competition for limited water resources than violent conflict. Three earlier studies have found a positive statistical relationship between shared rivers and low-level interstate conflict. Based on a more comprehensive dataset, an improved model of conflict, and a more appropriate control for geographical opportunity, we argue that these results are spurious and that we cannot establish a conflict-inducing effect of shared rivers over and beyond contiguity itself. In fact, the new dataset presented here makes it clear that nearly all neighbors in the international system share at least one river. This calls for a different approach to investigating interaction in shared river basins. This notwithstanding, freshwater and other shared resources may still provide a mechanism to explain why contiguity is robustly associated with conflict, so the water-conflict scenario cannot be dismissed. Indeed, our results show that among river-sharing states, basins with an upstream/downstream configuration increase the risk of conflict. The article finally discusses how river interaction should be further investigated based on these results and what new data are needed to enable such research.     

An Empirically Based Implementation and Evaluation of a Hierarchical Model for Commuting Flows. 一种基于经验的层状通勤流模型实现与评估

This article provides an empirical evaluation of a hierarchical approach to modeling commuting flows. As the gravity family of spatial interaction models represents a benchmark for empirical evaluation, we begin by reviewing basic aspects of these models. The hierarchical modeling framework is the same that Thorsen, Ubøe, and Nævdal (1999) used. However, because some modifications are required to construct a more workable model, we undertake a relatively detailed presentation of the model, rather than merely referring to the presentation in Thorsen, Ubøe, and Nævdal (1999) . The model uses a hierarchical specification of a transportation network and the individual search procedure. Journeys to work are determined by the effects of distance deterrence and of intervening opportunities, and by the location of potential destinations relative to alternatives at subsequent levels in a transportation network. The model calibration uses commuting data from a region in western Norway. The estimated parameter values are reasonable, and the explanatory power is very satisfactory when compared with the results of a competing destinations approach.     

Empirical Evaluation of Alternative Model Specifications to Predict Commuting Flows

This study is devoted to empirical and modeling aspects on how characteristics of spatial structure influence commuting flows. Within a doubly-constrained framework, results from a competing-destinations formulation are evaluated and compared to results from the traditional gravity model. The evaluation depends critically upon the specification of within-zone journeys-to-work. Specific labor-market characteristics are found to be significant to explain how workers are absorbed in diagonal elements of the trip-distribution matrix. We also find that the parametric specification of the accessibility measure is important, and that the competing-destinations formulation is superior to the traditional gravity model.     

Surviving Between the Trenches: Planning Research,Methodology and Theory of Science

Planning research-understood as research aiming to improve the body of knowledge on which spatial planning is based-includes issues rooted both in the social sciences, natural science and the humanities. Spatial planners need knowledge about the likely consequences of different alternatives of action, as well as understanding of the role of plans and planning processes in the development of society. This is reflected in the two-fold focus of planning research on both substantive and procedural issues. Whereas research on the role of plans and planning processes takes place mainly within a non-positivist social science paradigm, the research aiming to provide planners with the knowledge needed in order to make good plans is often situated in the battlefield between opposing positions within theory of science. Because planning research has both society and the physical as its subject of inquiry, a reflective opinion about the interaction between the physical environment and human actions is crucial. Traditionally, many spatial planners have conceived of this in a quite näive way, assuming that human behaviour can to a high extent be shaped or controlled by manipulating the physical environment. During recent decades, this view has been sharply criticized by anti-positivist scholars, and some theorists point out the great uncertainty, close to impossibility, in predicting human actions, even at an aggregate scale. The latter position has dramatic implications to spatial planning, as it would then be impossible to assess whether a certain physical solution is likely to have positive or negative social and related environmental consequences, e.g. in terms of travelling distances and modal split. Our own position is that the physical environment, along with a number of individual and non-physical structural factors, influences human activities and quality of life. To some extent, this influence can be predicted at an aggregate scale, but not for a particular individual (except those actions rendered impossible by the laws of physics). How strong influence the physical environment exerts, is a question requiring empirical research in order to be answered.

MAOISM IN NORWAY

The Maoist movement was the most visible expression of the 1968 uprising in Norway. But the Maoists soon waved goodbye to the anti‐authoritarian vibes of 1968, and what had started out as a pacifist and slightly anarchistic movement, soon evolved into one of the strongest Marxist–Leninist movements in the Western world in the 1970s. Maoism was first and foremost an imported package, but found fertile soil in the egalitarian and to some extent puritan Norway.     

A review of archaeological research on sami prehistory

Abstract

The English botanist and gardener John Tradescant the Elder's diary from a voyage to northern Russia in 1618 has lately attracted attention as a potential source on early Russian sea mammal hunting on the Svalbard archipelago. This article examines the usefulness of Tradescant's diary in this respect, but comes to a negative conclusion.     

Oslo's Farewell to Urban Sprawl

Sustainable mobility has been an important concern in urban planning and development in Oslo Metropolitan Area since the 1990s. The period has been characterized by concentrated and compact urban development, especially within the municipality of Oslo. This has contributed to a reduction in growth in car traffic. Analyses of selected land use and transport plans and policy documents, professional journal articles and interviews with key actors show that there has been a high degree of consensus about this spatial development strategy. Considerable investments have been made in public transport as well as in road development; the former based on broad consensus. Road capacity increases have been contested among professionals but widely supported by politicians.
