Parents of global youth: contesting debt and belonging

In the United States, recently arrived migrant youth encounter competing media and institutional discourses that cast them as dependents who have been rendered ‘left behind,’ ‘on their own,’ or ‘unaccompanied’ by their parents. A corresponding narrative emerges in which young migrants’ parents are framed as abusive, neglectful, and ignorant. Combined, these portrayals may garner specialized services and contribute to success in the legal realm. At the same time, however, they fail to recognize and even imperil the intimate intergenerational networks that facilitate transnational migration. In this article, we trace the homogenizing power of public discourses on young people and their families across two diverse ethnographic contexts, that of Chinese and Guatemalan migration. Focusing in particular on narratives of debt and belonging, we argue that the pervasive pathologization of migrant youths’ parents diminishes and contorts valued relationships over time. It correspondingly demands broader efforts to historicize and to contextualize youth mobility.     

Negotiating emotions,rethinking otherness in suburban Melbourne

I argue that research that tries to makes sense of emotion provides a better understanding of the politics and ethics of doing face-to-face research. Reflecting on in-depth interviews with people who live and/or work in Dandenong, an outer suburban area of Melbourne, I draw attention to the emotional dimensions of the research process. In particular I focus on moments when the exercise of white privilege made it difficult to negotiate emotions. These were moments when the intersection of my ethnicity with my position as a new settler in Dandenong made me feel excluded. The outcome was that I found it hard to value the voice of participants who were eager to help me with my research. A critical reflection of the emotions produced during such interpersonal encounters, however, has enabled me to rethink moments when the Self/Other binary unintentionally emerged. Critical self-reflexivity that is attentive to emotions gave me the opportunity to move closer to my goal of being an ethical researcher.     

Toward an understanding of the exchange in ancient scented oils through organic residue analysis of Bronze Age Near Eastern ceramic bottles by GC-MS

This paper presents a gas chromatography-mass spectrometry (GC-MS) organic residue analysis (ORA) of samples extracted from five Early Bronze Age ceramic bottles excavated at the archaeological site of Küllüoba in Anatolia (modern Turkey), and the first attempt at directly analysing the content of this category of products. Our results show that various types of liquid have been contained in different bottles and identify the presence of dicarboxylic and oleic acids with a large amount of palmitic acid in most samples, suggesting that they may have mostly contained a plant-based oil. The presence of diterpenoids further shows the addition of ingredients such as conifer resin and other plant-derived products. Overall, the analytical results presented here indicate the exchange of scented oils in Anatolia already during the late third millennium BCE. The different organic residue profiles contained in different samples also suggest a range of different recipes for these products.     

An archaeometric study of the Konya basin metallic ware through FTIR and XRD analysis with chemometrics: Central Anatolian Early Bronze Age ceramics

Fourier-transform infrared, X-ray diffraction and chemometrics were used to characterize the mineralogical composition and firing conditions of 59 Early Bronze Age ceramic sherds from the Konya Plain (Turkey). These include the Konya Basin Metallic Ware (KBMW) and a control group of contemporary local products. The analysis indicates significant differences in mineral inclusions and firing temperatures, with KBMW generally being fired above 800°C and characterized by standardized fabric recipes. Assessed together with other published evidence, these results indicate a high degree of specialization in the production of KBMW ceramic assemblages in central Anatolia during the third millennium BCE.     

The Dark Side of Transformation: Latent Risks in Contemporary Sustainability Discourse

The notion of transformation is gaining traction in contemporary sustainability debates. New ways of theorising and supporting transformations are emerging and, so the argument goes, opening exciting spaces to (re)imagine and (re)structure radically different futures. Yet, questions remain about how the term is being translated from an academic concept into an assemblage of normative policies and practices, and how this process might shape social, political, and environmental change. Motivated by these questions, we identify five latent risks associated with discourse that frames transformation as apolitical and/or inevitable. We refer to these risks as the dark side of transformation. While we cannot predict the future of radical transformations towards sustainability, we suggest that scientists, policymakers, and practitioners need to consider such change in more inherently plural and political ways.     

Analysis of the Effect of Provisional Ties on the Construction and Current Deformation of Mallorca Cathedral

This article presents the analysis of the structure of Mallorca Cathedral taking into account the influence on the structural behavior of auxiliary iron ties used during the construction process. Recent studies (Roca et al. 2012, 2013) presented some hypotheses about the construction process of the cathedral. This article complements the previous results by considering the use of auxiliary ties as temporary stabilizing device during the construction. Evidence of the use of ties during the construction has been recognized after a comprehensive survey. The study of the role of such ties and the effect of their later removal are studied by a FE analysis carried out on a representative bay of the structure. The study includes a time-dependent FE analysis after the removal of the ties to assess the long-term structural behavior. The results of the numerical analysis are compared with the deformation trends identified by means of a recent monitoring campaign.     

Spatial Autocorrelation Statistics of Areal Prevalence Rates under High Uncertainty in Denominator Data

We propose a new estimator of spatial autocorrelation of areal incidence or prevalence rates in small areas, such as crime and health indicators, for correcting spatially heterogeneous sampling errors in denominator data. The approach is dubbed the heteroscedasticity‐consistent empirical Bayes (HC‐EB) method. As American Community Survey (ACS) data have been released to the public for small census geographies, small‐area estimates now form the demographic landscape of neighborhoods. Meanwhile, there is growing awareness of the diminished statistical validity of global and local Moran’s I when such small‐area estimates are used in denominator data. Using teen birth rates by census tracts in Mecklenburg County, North Carolina, we present comparisons of conventional and new HC‐EB estimates of Global and Local Moran’s I statistics created on ACS data, along with estimates on ground truth values from the 2010 decennial census. Results show that the new adjustment method dramatically enhances the statistical validity of global and local spatial autocorrelation statistics.     

Modeling and deterioration mapping of façades in historical urban context by close-range ultra-lightweight UAVs photogrammetry

Deterioration mapping of façades may be a challenging task in historical urban contexts, often characterized by narrow streets and tall buildings. In these situations, the application of Terrestrial Laser Scanning or Terrestrial Photogrammetry does not provide satisfactory results. Furthermore, the use of Unmanned Aerial Vehicles, the so-called “drones”, is generally forbidden in crowded places for safety reasons unless they are lighter than a weight imposed by the regulations in force in each country. This article presents the application of a very small and ultra-lightweight drone (less than 300 g) equipped with a low-cost camera, particularly suitable for operating in very narrow spaces. A close range photogrammetric survey performed to analyze a huge historical building façade in Bologna (Italy) pointed out a good accuracy level, confirmed by the validation of the results carried out by a 3D laser scanner survey. Moreover, a map of the degradation has been realized to support further restoration analysis, demonstrating that this low-cost, fast, and easy-to-use survey technique can be applied to other similar urban contexts at the same time.
