A Dynamic Household Model for the Housing Market of Amsterdam

This paper addresses the issue of incorporating household dynamics into operational dynamic urban models. Dynamic model approaches that can be used to model urban change are introduced and discussed. We conclude that these different approaches are best combined in an accounting framework. An example of an accounting framework for a dynamic model of Amsterdam is presented. The household submodel is discussed in detail and some preliminary results are given.     

Post-Roman crop production and processing: Archaeological evidence from Goldthorpe,South Yorkshire

The remains of a ditched field system dating from the late Iron Age to the early post-Roman period, and two associated corn drying ovens (dating to the 5th–6th centuries AD) were revealed during archaeological excavations at Goldthorpe, South Yorkshire. The site was excavated during 2012 and 2013, during which bulk environmental samples were taken in order to retrieve any surviving botanical remains from deposits associated with the corn drying ovens, and other features across the excavated area. Early post-Roman occupation is under-represented in the archaeological record, especially in northern England, as such human activity and subsistence during this period are currently not well understood. This paper combines evidence for the field system, the physical remains of the corn drying ovens and their associated botanical remains to further understand early post-Roman change and continuity in landscape use and crop production and processing practices.     

Ruwayda: an historic urban settlement in north Qatar

SUMMARY: Ruwayda was first identified as an archaeological site in the 1970s and was excavated between 2009 and 2014. Despite a paucity of documentary evidence, this large settlement, which extends over an area of more than 90 hectares, contains a number of features indicative of an urban settlement including two mosques, a series of warehouses, a large multi-period fort, large courtyard houses interspersed with smaller, less substantial structures and a number of cemeteries. In addition to these buildings, there is also evidence for associated field systems and a walled garden.     

Simultaneous-Equation Systems Involving Binary Choice Variables

Simultaneous-equation systems of continuous variables are well known in the social sciences. Unfortunately, these methods cannot be used when dealing with discrete endogenous variables. Although for discrete types of data a broad range of methods and techniques have been developed, their applicability is restricted to single-equation systems (for example, logit or probit formulations) or to association-type models (log-linear models), mainly because of the lack of suitable estimation methods and computer programs. The basic problem is the multivariate error structure of the endogenous variables. This paper presents a simultaneous-equation system of binary endogenous variables. The model is applied empirically to longitudinal data on mode choice and is compared with the well-known log-linear model.
