Bayesian Spatial Filtering for Hedonic Models: An Application for the Real Estate Market

This article presents a Bayesian method based on spatial filtering to estimate hedonic models for dwelling prices with geographically varying coefficients. A Bayesian Adaptive Sampling algorithm for variable selection is used, which makes it possible to select the most appropriate filters for each hedonic coefficient. This approach explores the model space more systematically and takes into account the uncertainty associated with model estimation and selection processes. The methodology is illustrated with an application for the real estate market in the Spanish city of Zaragoza and with simulated data. In addition, an exhaustive comparison study with a set of alternatives strategies used in the literature is carried out. Our results show that the proposed Bayesian procedures are competitive in terms of prediction; more accurate results are obtained in the estimation of the regression coefficients of the model, and the multicollinearity problems associated with the estimation of the regression coefficients are solved.     

Differentiation of archaeological maize (Zea mays L.) from native wild grasses based on starch grain morphology. Cases from the Central Pampas of Argentina

This paper presents, for the first time, a detailed study, from an archaeological perspective, of the morphological characteristics of the starch grains within the kernels of selected native wild grasses found in the Central Pampas of Argentina. We compared native wild grasses to maize starch grains, which can be distinguished from each other based on their size, shape and other attributes. The majority of the studied grains did not share morphological characteristics with maize starch grains. Considering this, it can be said that, if irregular and polyhedral grains with transverse or radial fissures dominate the starch assemblage, maize identification may be done on the basis of both morphology and size. Additionally, this research contributes to the characterization of the starch grains of the Panicoideae subfamily, which includes maize. Several classes of simple and compound starch grains are described and defined for native species of Pooideae, Chloridoideae, Arundinoideae, and Panicoideae subfamilies. The results obtained may constitute a baseline for the future determination of maize and wild grass use in archaeological contexts belonging to Middle/Late Holocene hunter–gatherers in the Pampas of Argentina and neighboring areas.     

Vulnerability Index: A New Approach for Preventive Conservation of Monuments

A new approach is developed for vulnerability analysis of monuments based on a matrix model and the relationships with static and structural factors, climatic conditions, air quality, urban planning and social agents for preventive conservation of cultural heritage in urban centers.

The objective is to provide tools for decision-makers in the current recession to allow them to prioritize strategies for cultural heritage preservation in a town, where territorial policies are applied and regions where restoration budget is distributed. This new tool allows to classify monuments in order to prioritize restoration and is useful in deeper analysis associated to risks assessment.

The degradation of building materials and structures is mainly due to deterioration caused by structural instability, weathering, pollution, and anthropogenic damage. The vulnerability approach of each monument (vulnerability indexes) was calculated, based on a Leopold matrix that depends on intrinsic variables and the life of the monuments. For the very first time, the influence of different deterioration agents has been balanced with a Delphi forecast based on architects’ opinions.

The result is a new pre-Artificial Intelligence tool that enables users to reproduce human reasoning to study relations between vulnerability factors, risk factors, and the historical parameters of the monuments.     

Our Privilege and Co-responsibility in the Protection of the Underwater Cultural Heritage

Mexico’s National Institute of Anthropology and History established an ethical program for the protection and research of the country’s underwater cultural heritage (UCH). Its Vice-Directorate of Underwater Archaeology trains archaeology and conservation students, participates in national and international initiatives regarding UCH, and develops multidisciplinary projects in maritime and continental waters. During negotiation of the UNESCO Convention, the Latin American and Caribbean Group united in a strong voice and contributed to its adoption in 2001; in 2006, Mexico ratified the Convention. This article highlights Mexico’s adoption of the 2001 UNESCO Convention as a case study, to stimulate all countries to ratify the convention and to cooperate in protecting the world’s UCH.

Maize and Bone: Residues of Grinding in Northwestern Argentina*

Archaeometric and archaeobotanical analyses of grinding residues inside an archaeological milling stone tool from the Cueva de los Corrales 1 site in northwestern Argentina are shown. Multiple analytical techniques are used to identify ground substances, and their results are compared and complemented. They give direct and reliable evidence of maize (Zea mays L.) and burned bone grinding in the pre‐hispanic Argentine north‐west, although the latter is little related to milling tasks.     

The representation of non-Irish immigrants in recent Irish films

This paper examines the representation of ethnic and racial minorities in Celtic Tiger and post-Celtic Tiger films such as Adam and Paul (2004), Pavee Lackeen (2005), Once (2006), The Front Line (2007), and New Boy (2007). Key areas of analysis include: how is immigration represented on screen? Whose character's point of view predominates? How much space do these ethnic minorities occupy in the shot? In order to answer these research questions, I draw on a plurality of theoretical paradigms currently employed in film theory, mainly narrative theory, critical race theory and feminist theory. As I show, the differences between these films are paramount and will inform the different ways in which recent Irish cinema represents racial and ethnic Otherness. In some films, immigrants appear mainly as decorative props and they largely function as cinematic elements which emphasise the marginalisation of other “inner” Irish outsiders, particularly drug addicts and Travellers. By contrast, other films make serious attempts to see “into” or “through” immigrant characters by fictionalising not only the point of view of natives but also of newcomers themselves.
