A Diachronic Study of Networks of Ceramic Assemblage Similarity in Neolithic Western Anatolia,the Aegean and the Balkans (c.6600–5500 bc)

This study compares the results of Jaccard and Kulczynski‐2 similarity measures on a sample of ceramic assemblages to reveal spatio‐temporal patterns in the relationship between Neolithic sites in western Anatolia and south‐eastern Europe (c.6600–5500 bc ). The results show that the relationship between spatial distance and ceramic assemblage similarity has increased through time, which supports previous interpretations of leapfrog migrations and subsequent regionalization in ceramic assemblages during the Neolithic. A diachronic network analysis demonstrates the continuation of Aegean networking after the spread of farming.     

Spatial equilibrium in deviations: An application to skill‐premium and skill‐mix heterogeneity

In this paper, we propose a novel—and general‐purpose—modeling approach. We give a linear representation of the spatial general equilibrium, expressed in terms of local percentage deviations from the benchmark case of symmetry, where all the areas in the economy are taken to be initially identical. To illustrate the flexibility of our approach, we revisit the literature on the spatial heterogeneity of local skill premia and local skill mix. We show that our approach is able to encompass a variety of alternative explanations in a simple “unifying framework.” Finally, we exploit a graphical version of the model to show how to implement empirical tests.     

Emer Martin and multimodal family dysfunction: More Bread or I’ll Appear (1999)

Emer Martin’s More Bread or I’ll Appear (1999) revisits the discourse of the family in Ireland between the 1970s and the 1990s. This article contends that Martin intersects her work with family “issues” of the day so as to accommodate the representation of what can be termed as multimodal family dysfunction. She provides insights to the role of women, family and global female diaspora. This paper draws upon work by Diarmaid Ferriter, Alpha Connelly and the tenets of transnational feminism to account for the historical, ideological and sociocultural contexts of the time. For Martin, dysfunction is multimodal in the way in which the Irish family portrayed faces real “hidden issues” from different discourses. Her novel also focuses on the “wounds” that have been the effect of abuse, secrets, appearances, violence and lack of communication within the family. Another mode of Martin’s representation of dysfunction considers the transnational experiences of her female characters on the margins of an Ireland becoming global. Her novel invokes transnational perspectives so as to commit to dislodging nation-centric and family-centric visions of Ireland.     

Analytical study of Roman and Arabic wall paintings in the Patio De Banderas of Reales Alcazares’ Palace using non-destructive XRD/XRF and complementary techniques

A portable XRD/XRF system and complementary laboratory techniques were employed to improve the knowledge of the procedures used to create Roman and Arabic wall paintings. Integrated physico-chemical investigations were conducted on fragments of artworks collected from the archaeological excavation of the Patio de Banderas in the Reales Alcazares’ Palace of Seville (Spain), and a comparative study on the pigments from both historical periods was performed. As a result, pigments such as vermilion, red ochre, yellow ochre, green earth, Egyptian blue, carbon and phosphor-based black pigments were detected in Roman samples; however, in the Arabic fragments, only haematite was observed. In addition, the size and shape of the particles of the wall paintings were studied with an XRD 2-dimensional detector and SEM-EDX.     

Characterization and origin of black and red Magdalenian pigments from Grottes de la Garenne (Vallée moyenne de la Creuse-France): a mineralogical and geochemical approach of the study of prehistorical paintings

Pigments sampled from wall paintings and from crayons taken on the floor, at the Grottes de la Garenne (Saint-Marcel – Indre, France) have been analyzed and characterized by infrared spectroscopy, Raman micro-spectroscopy, X-ray diffraction, ICP/MS and analytical TEM. The red pigment used for the wall paintings is mainly composed by hematite, clays, carbon matter and carbonates. Results on the red pigments show that the compositions of the paintings are similar to that of some crayons. Regarding these analyses, their origin is compatible with local siderolithic facieses. Analysis of black pigments shows that they are made of cryptomelane, pyrolusite, clays, carbonates and carbon matter. It shows also that paintings and some crayons compositions are compatible. On the contrary of red pigments, the origin of black pigments is probably allochtonous. Indeed, the traces of thallium detected in cryptomelane, the cerium anomaly and the absence of iron are not compatible with local facieses or other sites from the French Massif Central.     

Contribution of the resistivity method to characterize mud walls in a very dry region and comparison with GPR

Mud walls are frequent in many archaeological sites, including sites located in semi-desert regions. In cases with buried walls, the geophysical methods can be useful tools for their investigation, since they provide maps of the subsoil in a non-invasive way and in relatively short times. This article deals with the characterization of mud walls in very dry soils through the resistivity method, discussing a methodology to satisfactorily apply the method in this kind of adverse environment and how to interpret the results. The case of the Palo Blanco archaeological site, a pre-Incaic village located in the NW region of Argentina, is analyzed.     

Carbon Sequestration in Community Forests: Trade‐offs,Multiple Outcomes and Institutional Diversity in the Bolivian Amazon

Carbon sequestration in community forests presents a major challenge for the Reducing Emissions from Deforestation and Forest Degradation (REDD+) programme. This article uses a comparative analysis of the agricultural and forestry practices of indigenous peoples and settlers in the Bolivian Amazon to show how community‐level institutions regulate the trade‐offs between community livelihoods, forest species diversity, and carbon sequestration. The authors argue that REDD+ implementation in such areas runs the risk of: 1) reinforcing economic inequalities based on previous and potential land use impacts on ecosystems (baseline), depending on the socio‐cultural groups targeted; 2) increasing pressure on land used for food production, possibly reducing food security and redirecting labour towards scarce off‐farm income opportunities; 3) increasing dependence on external funding and carbon market fluctuations instead of local production strategies; and 4) further incentivising the privatization and commodification of land to avoid transaction costs associated with collective property rights. The article also advises against taking a strictly economic, market‐based approach to carbon sequestration, arguing that such an approach could endanger fragile socio‐ecological systems. REDD+ schemes should directly support existing efforts towards forest sustainability rather than simply compensating local land users for avoiding deforestation and forest degradation.     

Public Perceptions of Expert Credibility on Policy Issues: The Role of Expert Framing and Political Worldviews

How do individuals assess the credibility of experts in various policy domains? Under what conditions does the public interpret particular scientific knowledge claims as being trustworthy and credible? Using data collected from an online survey experiment, administered to 1,507 adult residents of Quebec, this paper seeks answers to these questions. Specifically, we examine variation in the way members of the public perceive the credibility of scientific experts in the areas of climate change, shale gas extraction, cell phones, and wind farms. Our results contribute to the existing literatures on public perceptions of policy experts, framing, and cultural theory. We find that individuals evaluate expert credibility based on the way in which experts frame issues, and on the congruity/dissonance between these expert communication frames and one's underlying worldview. However, we also identify limits to these framing effects. Our findings shed light on the interaction of framing and political worldviews in shaping public perceptions of expert credibility in various policymaking contexts.
