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.     

Challenges to Bridging Discrepant Knowledge Bases: A Case Study of the Norwegian Centre for Offshore Wind Energy

From a theoretical perspective, it is possible to enhance the innovation of firms and institutions by combining the analytic (scientific) knowledge base of research and development (R&D) institutions with the synthetic (practical) knowledge base of industries. Such combinations of knowledge are also believed to support regional development. One such initiative to bridge knowledge from the R&D sector and industry is the Norwegian Centre for Offshore Wind Energy (NORCOWE). However, as our case study shows, it is hard to bridge knowledge from these two partner groups. We found that this is mainly because of differences in the partners' timelines (long versus short), their attitudes toward knowledge (research based versus experience based), application of the knowledge (knowledge per se versus commercialization), and organizational dimensions (linear/closed process versus interactive/open process). These differences show that the knowledge bases of these two groups may not just be different; they can also be seen as discrepant. We also argue that the NORCOWE initiative is influenced by a “policy push” logic. This implies that the initiative was not properly embedded in the industrial or R&D institutions before being launched, but was instead driven by a political will to promote the development of a new renewable energy source.     

ON PITCHFORKS AND TOMAHAWKS*

ABSTRACT The core‐periphery model of the new economic geography has two “dramatic” implications: catastrophic agglomeration and locational hysteresis around the symmetry breaking level of trade freeness. In this note, we study a generalized version of this model with constant elasticity of substitution (CES) instead of Cobb‐Douglas upper tier preferences. The possibility of a continuous and easily reversible transition from symmetry to agglomeration now arises. One of the most prominent results of the new economic geography literature—the catastrophic consequences of small parameter changes—therefore, hinges crucially on specific functional forms for consumer preferences.

Saul and Cultural Memory

ABSTRACT

In recent years a number of biblical scholars have shown that the Hebrew Bible contains both the collective memory and amnesia of ancient Israel. The differences between the portrayals of Saul in the books of Samuel and 1 Chronicles have long been explained in terms of redaction history, inner-biblical exegesis and other intertextual reading strategies. Using the insights from the fields of sociology and psychology cultural memory theory suggests that it was the dynamics of structural amnesia that made it necessary to suppress the memories of Saul that were not useful to the reconstruction of the past, and that the new “master narrative” in the Book of Chronicles may be seen as a post-trauma solution to the Israelites’ painful retrieval of memories of guilt and trauma.
