The Determinants of Regional Freight Transport: A Spatial,Semiparametric Approach

In the context of modeling regional freight the four‐stage model is a popular choice. The first stage of the model, freight generation and attraction, however, suffers from three shortcomings: first of all, it does not take spatial dependencies among regions into account, thus potentially yielding biased estimates. Second, there is no clear consensus in the literature as to the choice of explanatory variables. Second, sectoral employment and gross value added are used to explain freight generation, whereas some recent publications emphasize the importance of variables which measure the amount of logistical activity in a region. Third, there is a lack of consensus regarding the functional form of the explanatory variables. Multiple recent studies emphasize nonlinear influences of selected variables. This article addresses these shortcomings by using a spatial variant of the classic freight generation and attraction models combined with a penalized spline framework to model the explanatory variables in a semiparametric fashion. Moreover, a Bayesian estimation approach is used, coupled with a penalized Normal inverse‐Gamma prior structure, to introduce uncertainty regarding the choice and functional form of explanatory variables. The performance of the model is assessed on a real‐world example of freight generation and attraction of 258 European NUTS‐2 level regions, covering 25 European countries.

Elementary Spatial Systems of Industrial Production

An elementary spatial system of industrial production is conceptualized as the primary geographical formation in industry. Such an elementary production system (EPS) is viewed as consisting of raw-material and consumption nodes connected by lines of movement with a single production node. Besides the measures proposed by Kansky (University of Chicago, Research Paper 84, 1963), such a system, represented in the form of a connected, directed graph, can be described by measures of material and spatial transformation and by indices of dispersion of aggregate nodes. Characteristic properties of EPS are the spatial attraction between nodes and the spatial coincidence and intersection of common nodes of two or more systems. The usual Weberian movement-minimization approach to the building of a model of such an elementary production system is judged to be inadequate because it ignores local differences in production costs, and a “field of potential costs” is proposed instead to take account of the total cost picture.

Something for posterity or hostage to fortune? Archiving anthropological field material (Respond to this article at http://www.therai.org.uk/at/debate)

What do anthropologists do with all the data (both primary and secondary) they accumulate while doing fieldwork? Most continue to draw on it for many years, but there is increasing pressure (e.g. from the ESRC) to place much of it in archives, usually in electronic form. What kind of material could be deposited? What use may be made of such material by others? What are the ethical dilemmas which face anthropologists in depositing confidential data? Are there differences between paper and electronic archives and between textual and other forms of material, such as photos and sound recordings? How can anthropologists best protect their sources? Does anthropology become a form of historiography when its raw data are archived? What forms of ‘knowledge’ are created by archiving?     

Skeletal health and patterns of animal food consumption at S3W1:33 (Tlajinga 33), Teotihuacan

Food at Teotihuacan was more likely affected by social inequality than by availability. The skeletons from Tlajinga 33 have high prevalence of skeletal indicators of morbidity. Since this was a lower-status compound of artisans, this could be due to poor diet, as well as an unhygienic environment. Analysis of faunal remains suggests that animal remains were an important and plentiful component of the diet. However, most consist of insects, small fish, reptiles, avian eggs, and small mammals. Of particular importance is the size and nutritional value of these dietary items, as many would be considered vermin which were available solely because of attraction to stored foods. It is important to employ proper recovery techniques to eliminate bias in size of animal remains to obtain an accurate understanding of the total diet. We demonstrate that there was adequate animal protein in the Tlajinga 33 diet, but it was very different than what is usually considered “animal protein.” Thus, the residents had access to a nutritious and balanced diet, and this information eliminates protein deficiency as cause of the morbidity. Instead, the focus is on the urban environment and any status disadvantages faced by residents dependent on market exchange for staple foods.     

COMPUTATION OF MAXIMUM LIKELIHOOD ESTIMATES OF GRAVITY MODEL PARAMETERS*

ABSTRACT. This paper presents the derivations of several new algorithms for the computation of maximum likelihood estimates of the parameters of a very general form of the gravity model. The algorithms are then compared with previously available algorithms including GLIM and that given in Sen (1986). One of the new algorithms emerges as far superior in just about every way to its competitors. In particular, it is usually much more than an order of magnitude faster than the GLIM procedure and that given in Sen (1986). It is also not substantially affected by pitfalls such as multicollinearity and (unlike the GLIM procedure) is capable of comfortably handling large O-D matrices.     

New Estimates of Gravitational Attraction by Linear Programming

This paper uses data for intercity air-passenger travel to derive a set of general propulsion and attraction factors for twenty-five large U.S. cities. The paper develops a new way of examining the linkages between flows and nodal attraction. The technique is to assume that the flow data fit a simple gravity model, and then linear programming is used to maximize the consistency of the endogenous propulsion and attraction with the flow data. Various linear models are used to determine the pattern of urban attraction factors that are consistent with the gravitational flows. Linear programming as well as goal programming models are used to develop a set of analyses linking flows to urban hierarchies. Suggestions for further extensions of the method to address substantive issues of urban systems analysis are also provided.     

The Magnetic Field Model Applied to Swedish Settlements

To study the reason for changes in the population of urban settlements and sparsely populated districts we need an approach on a regional geographic level that will combine various theoretical elements and which, taken together, will provide an interdisciplinary platform. The identity of a place is created by specific local factors as well as by social and economic processes occurring both in the place itself and in the urban system. We can use indications showing how local and regional urban systems function in order to ascertain why one urban settlement grows while another stagnates, why a sparsely populated district in one region flourishes while other districts languish. Using the decision-making point of view adopted by households and businesses will help us to achieve our aim.
The starting point of the model employed—called the magnetic field model—is the fact that an attraction field of positive factors forms in and around places with a growing population. The aim of this paper is to show that a regional geographic analysis can be made from a number of indicators of significance for the development of populations in urban settlements and sparsely populated districts. Naturally these indicators can—and should—be queried, added to and assessed when other, similar investigations are carried out.     

Becoming modern: British-Indian discourses of arranged marriages

This article looks at the various ways in which arranged marriage is practised among members of the British-Indian population. It argues against a singular definition of this practice by highlighting the diversity of routes that lead to an arranged marriage. It also makes a case for understanding arranged marriage as a discursive practice which represents the British-Indian views on matchmaking and kinship. Drawing upon original empirical research conducted in the north-east of England, the article presents a ‘spectrum of arranged marriage’ practices that was prevalent among its practitioners. It highlights that the attraction of this institution lies in the elastic nature of the traditions associated with it. Finally, it proposes that the various discourses of arranged marriage are employed by British-Indians to interpret and tailor-make this traditional practice to carve out hyphenated identities such as British-Indian and other transnational forms of belonging. They achieve this by incorporating the demands of modernity such as the notion of romantic love and a certain level of individual choice within arranged marriage practices.
