A Network Approach to Commuting

In this paper we present a model for commuting in a network of towns. A basic assumption is that all individuals have a given residential location and that every node in the network has a fixed number of jobs. We then propose a general model for the commuting of labor between the nodes in the network.     

Dat Scaecspel: a profane-ethical exploration

The Dutch translation of Jacobus de Cessolis' Ludus scaccorum is an adaptation of the Latin text with so many interventions from the Dutch translator that the Dutch version becomes an independent plea for just behaviour. The context is presumably that of the Dutch comtal court of 1400.     

Partitioning chi-square for the analysis of frequency table data: an archaeological application

Archaeologists often wish to compare observed frequency distributions with expectations generated by a model. We describe a technique of partitioning chisquare which yields information about goodness of fit to a model and about homogeneity among populations simultaneously, and which is often superior to other commonly used methods of evaluating frequency data. The technique is demonstrated with data from the Upper Paleolithic rockshelter Le Flageolet I. The results suggest selective raw material use by the Aurignacian occupants.     

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.

First results of metallographic analysis and absolute dating of iron finds from Nowe Brzesko,site 26, Proszowice District

This paper presents the results of analyses of metal artefacts discovered at a multiphase site in Nowe Brzesko, Małopolskie Voivodeship, Poland. Fieldwalking prospection led to the discovery of steely iron objects, ploughed out on the site among other numerous archeological finds. A prospecting sondage yielded more corroded metal artefacts, identified mainly as agricultural tools (e.g. sickles, scythes). These chronologically nondistinctive artefacts could be assigned to the third to fourth century AD using radiocarbon dating, complemented by metallurgical analysis. The results open up new research perspectives on the economy and society of the Przeworsk culture in the Late Roman period.     

My Paradigm or Yours? Alternative Development,Post-Development,Reflexive Development

Alternative development has been concerned with alternative practices of development—participatory and people-centred—and with redefining the goals of development. Mainstream development has gradually been moving away from the preoccupation with economic growth toward a people-centred definition of development, for instance in human development. This raises the question in what way alternative development remains distinguishable from mainstream development—as a roving criticism, a development style, a profile of alternative positions regarding development agency, methodology, epistemology? Increasingly the claim is that alternative development represents an alternative paradigm. This is a problematic idea for four reasons: because whether paradigms apply to social science is questionable; because in development the concern is with policy frameworks rather than explanatory frameworks; because there are different views on whether a paradigm break with conventional development is desirable; and finally because the actual divergence in approaches to development is in some respects narrowing. There is a meaningful alternative development profile or package but there is no alternative development paradigm—nor should there be. Mainstream development is not what it used to be and it may be argued that the key question is rather whether growth and production are considered within or outside the people-centred development approach and whether this can rhyme with the structural adjustment programmes followed by the international financial institutions. Post-development may be interpreted as a neo-traditionalist reaction against modernity. More enabling as a perspective is reflexive development, in which a critique of science is viewed as part of development politics.     

First evidence of the production of Ginalski E5 button spurs from copper alloy in Central Europe

Ginalski-type E5 button spurs made from a Cu alloy are a characteristic attribute of the Middle Roman period in barbarian Europe. The find of part of a mould made of non-ferrous metal at the Luleč site in the district of Vyškov, Czech Republic, provided key evidence for explaining the issue of their production. The discovery of this unique artefact showed that based on current knowledge, the spurs made from a Cu alloy were also produced in the Middle Danube region and not only in Northeast Europe as had previously been thought.
