Death on the farm: Culling badgers in North Pembrokeshire (Respond to this article at http://www.therai.org.uk/at/debate)

The Welsh Assembly Government has recently announced its intention to cull all badgers from North Pembrokeshire on the grounds that they are vectors of bovine tuberculosis. This article considers some local reactions to this news, ranging from those who support the cull wholeheartedly to those who argue against it, and some of the reasons why people adopt different standpoints. The article considers a range of issues which help explain why people think as they do; these include perception of risk, ethnicity, ideas about animals and wildlife, the selective uses of both scientific literature and emotion, and finally some of the local and regional politics involved.     

Cull or vaccinate?: Badger politics in Wales

In this sequel to an article on the badger‐cull published in the April issue of 2010, the author provides an update on what is happening to the culls announced for North Pembrokeshire and for England.     

A Three-State Markov Model of Choice Behavior within Spatial Structures

This paper derives a simple mathematical model of spatial learning and choice by integrating several psychological theories, whose features accord with the results of empirical investigation in a previous paper [2]. A sample of homogeneous decision-makers are assumed to make a succession of selections from a given set of initially unknown spatial alternatives (for example, a set of shopping places for a good). The decision-makers pass through two states of “recognition” and “discrimination” learning, before reaching an equilibrium state. In the equilibrium state, decision-makers have sufficiently learned the attributes of the alternatives so that satisfactory choices are always made. These assumptions permit the derivation of mathematical expressions to answer two questions: first, what proportion of decision-makers will be in the equilibrium state after any given time interval, and second, what proportion of decision-makers will choose any designated spatial alternative after the same time interval. In the second case, the proportion of decision-makers choosing an alternative is predicted from the individuals' perceptions of the attributes of the alternatives. The paper concludes with an evaluation of the model and suggestions for its testing and further development.     

High Dynamic Range Imaging for Archaeological Recording

This paper notes the adoption of digital photography as a primary recording means within archaeology, and reviews some issues and problems that this presents. Particular attention is given to the problems of recording high-contrast scenes in archaeology and high dynamic range imaging using multiple exposures is suggested as a means of providing an archive of high-contrast scenes that can later be tone-mapped to provide a variety of visualisations. Exposure fusion is also considered, although it is noted that this has some disadvantages. Three case studies are then presented: (1) a very high-contrast photograph taken from within a rock-cut tomb at Cala Morell, Menorca, (2) an archaeological test pitting exercise requiring rapid acquisition of photographic records in challenging circumstances and (3) legacy material consisting of three differently exposed colour positive (slide) photographs of the same scene. In each case, high dynamic range (HDR) methods are shown to significantly aid the generation of a high-quality illustrative record photograph, and it is concluded that HDR imaging could serve an effective role in archaeological photographic recording, although there remain problems of archiving and distributing HDR radiance map data.

The Mega-Site of Valencina de la Concepción (Seville,Spain): Debating Settlement Form,Monumentality and Aggregation in Southern Iberian Copper Age Societies

Study of the Iberian Copper Age has experienced a remarkable upheaval in the last two decades. The discovery in central and southwestern Iberia of a significant number of ditched enclosures, a site type almost unknown in this region until the mid 1990s, has opened up new lines of research. Particularly interesting is the existence of some exceptionally large sites. Largest of all is Valencina de la Concepción (Seville, Spain), covering an area of 450 ha and featuring several outstanding megalithic monuments, thousands of pits and material assemblages revealing middle and long distance contacts. In this paper we discuss the implications of the Valencina mega-site for the study of settlement variability, monumentality and population aggregation as key phenomena in the rise in social complexity in Copper Age Iberia.
