Can Dasymetric Mapping Significantly Improve Population Data Reallocation in a Dense Urban Area?

The issue of reallocating population figures from a set of geographical units onto another set of units has received a great deal of attention in the literature. Every other day, a new algorithm is proposed, claiming that it outperforms competitor procedures. Unfortunately, when the new (usually more complex) methods are applied to a new data set, the improvements attained are sometimes just marginal. The relationship cost‐effectiveness of the solutions is case‐dependent. The majority of studies have focused on large areas with heterogeneous population density distributions. The general conclusion is that as a rule more sophisticated methods are worth the effort. It could be argued, however, that when we work with a variable that varies gradually in relatively homogeneous small units, simple areal weighting methods could be sufficient and that ancillary variables would produce marginal improvements. For the case of reallocating census data, our study shows that, even under the above conditions, the most sophisticated approaches clearly yield the better results. After testing fourteen methods in Barcelona (Spain), the best results are attained using as ancillary variable the total dwelling area in each residential building. Our study shows the 3‐D methods as generating the better outcomes followed by multiclass 2‐D procedures, binary 2‐D approaches and areal weighting and 1‐D algorithms. The point‐based interpolation procedures are by far the ones producing the worst estimates.     

The politics of the public and private spheres: the High Court’s decision in Monis and the gendered privileging of free speech

The High Court of Australia’s decision in Monis v The Queen and Droudis v The Queen concerned whether Monis and Droudis’s use of the postal service to send offensive letters warranted the constitutional protection of the implied freedom of political communication. The outcome was a split decision: the three men judges found for Monis and Droudis, and the three women judges against. We argue that this decision was significant because it draws attention to the law’s key role in framing political understandings of the nature of and demarcation between public and private spheres. The Court’s interpretations concerning how we should understand and apply the foundational relationships binding the state, the individual, and the public and private spheres in the twenty-first century highlights the gendered complexities of the politics shaping those relationships. It also highlights the gendered privileging of what sort of speech should be exempted from the law’s immediate purview, and in so doing, further reveals the masculinism upon which Australia’s constitutional framework rests.     

Simulating archaeologists? Using agent-based modelling to improve battlefield excavations

The study of material culture generated by military engagements has created an emergent sub-discipline of archaeological studies centred on battlefields. This approach has developed a particular and sophisticated methodology that is able to deal with the fact that archaeologists will often not find either structures or a useful stratigraphical record on the site, as the material remains of the battle will basically be metallic objects carried by combatants. It is therefore rather complicated not only to test hypotheses about battle events based on archaeological data, but also to validate the methodology used. Here we propose the use of agent-based models to explore these issues in the case of eighteenth-century battlefield archaeology. The simulation is divided into four different steps. Firstly, a battle is simulated in order to generate realistic virtual archaeological remains left by an engagement between two armies of this era. We then simulate the loss of information that the passing of time produces in the battlefield. The third step involves simulating the archaeological survey, enabling us to explore different survey strategies and the impact on the interpretation of the event itself. Finally, we design a confidence index in order to compare the results of the different virtual excavations using spatial analysis and statistics. The results show that the methodology is fully functional in terms of understanding a battle, and it allows us to suggest new strategies to improve fieldwork and to develop new ways of exploring these particular archaeological sites. It is concluded that the described approach illustrates how simulation can be used to explore methodological issues of archaeological science.     

First evidence of white wine in ancient Egypt from Tutankhamun's tomb

Wine has been considered to be mainly red in ancient Egypt linked with the blood of Osiris, the God of resurrection. No text that refers to white wines from the Dynastic Period (3150–332 BC) exists. The first white wine from ancient Egypt was made near Alexandria during the third century AD. To investigate the presence of white wine in ancient Egypt, dry residue samples from King Tutankhamun's amphorae are studied in this article using the LC/MS/MS method for wine markers. This investigation into the existence of white wines in Tutankhamun's tomb allows us to shed new light on the symbolism of white wine in ancient Egypt.     

Detection of archaeological crop marks by using satellite QuickBird multispectral imagery

The capability of satellite QuickBird imagery for the identification of archaeological crop marks is herein presented and discussed for two test sites located in the South of Italy. The selected sites, dating back to Middle Ages, were buried under surfaces covered by herbaceous plants characterized by a different phenological status (dry/green) when the satellite data were acquired.
