Knowing “Good Food”: Immigrant Knowledge and the Racial Politics of Farmworker Food Insecurity

Abstract: This article explores the ways that farmworkers, many of whom come from a culture deeply rooted in food and agricultural practices, cope with food insecurity by utilizing their agricultural and nutritional knowledge. Food assistance providers in the USA often treat farmworkers' inability to afford healthy food as a lack of knowledge about healthy eating, reinforcing racialized assumptions that people of color don't know “good” food. I argue that in contrast to food banks and low‐income nutrition programs, home and community gardens provide spaces for retaining and highlighting agricultural, cultural, and dietary practices and knowledge. This paper investigates the linkages between workers' place in the food system as both producers and consumers, simultaneously exploited for their labor, and creating coping strategies utilizing agrarian and culinary knowledge. I argue that food security and healthy eating, rather than being a matter of consumers making healthy “choices”, is a matter of class‐based and racial differences in the food system.     

Turbo Island,Bristol: excavating a contemporary homeless place

This paper provides an assessment of the excavation of an apparently ordinary space in Bristol (UK) in 2009. Although the space appears unremarkable to most passers-by, it is unusual in being a place used routinely by many of the city’s street-drinking and homeless community. Homeless people were ‘colleagues’, involved in excavation, finds processing and interpretation. The collaborative nature of this project goes further than merely attempting to represent social groups who have traditionally been excluded from heritage practice and interpretation — it lays methodological foundations for praxis.     

A note on the excavation of an Ottoman and British Mandate period Bedouin campground at Nahal Be'erotayim West in the Negev desert,Israel

The preliminary results of excavations conducted at Nahal Be'erotayim West, an abandoned Bedouin campground in the Negev desert, Israel, indicate that multiple tents were pitched in this location in different periods and at different times of the year. The recovered artefacts and architecture provide a means to identify gender and seasonality in the archaeological record, respectively. Radiocarbon dates from an ash layer and two hearths offer evidence of intermittent occupation from the fifteenth to the nineteenth century AD, and chronologically diagnostic artefacts also indicate occupations from the late nineteenth to the mid‐twentieth century.     

Earth Sciences Comparative Matrix: A Comparative Method for Geoheritage Assessment

Geological heritage is insufficiently recognised in Australia; it should be considered in its own right, not as an addendum to other heritage values. The lack of a suitable robust and repeatable methodology has seriously constrained the assessment of geological sites suitable for the National Heritage List (NHL). A desktop assessment of Australian desert landscapes required intrinsic natural values of a diverse group of sites, spread over a vast area, to be assessed against NHL criteria. The Earth Sciences Comparative Matrix (ESCoM) was developed for this study. In the ESCoM, sites are grouped in process themes. Each is assessed against NHL criteria then compared with other similar places, according to degree of unusualness, integrity, and authenticity. A site scoring well across multiple themes has increased heritage significance. The overall values of a site are quantified, leading to a qualitative judgement on whether it achieves the threshold of outstanding heritage value. Examples of assessment using this method are given. In this methodology, significance determination is based on rigorous comparisons of specific values. It is semi‐quantitative, repeatable, and robust. It differs from other geoheritage assessment methods in its combination of process‐based groupings (facilitating the separation of site type from heritage criteria), matrix structure (minimising complexities of scale or diversity), and use of numerical rankings as an aid in decision‐making. While the study for which ESCoM was developed was focused on landforms, it can be used for other types of geoheritage (e.g. fossils, tectonic processes), with modification of matrix theme headings.     

Coupling Hydrotoponymy and GIS Cartography: A Case Study of Hydrohistorical Issues in Urban Groundwater Systems,Porto, NW Portugal

The aim of this multidisciplinary study is to retrospectively examine hydrohistorical issues, namely hydrogeographic, hydrotoponymical and hydrogeological features, in order to assess the evolution of the Porto urban groundwater system (NW Portugal). To achieve these goals, the comparison of two main field inventories in a large urban region was performed by (i) historical mapping of sources and groundwater data from scientific reports spanning the late 17th century to the early 20th; and (ii) hydrogeologic and hydrotoponymical field inventory performed under current conditions. These field inventories permitted the location of springs, dug wells, fountains, public washing places and underground water galleries, which collected groundwater to supply the population of Porto until the early 20th century. This study also allowed the development of a hydrotoponymical classification for urban areas and a field hydrotoponymical inventory data sheet. This research integrated several techniques based on historical hydrogeography, hydrogeology and urban geosciences. The results of the field inventories were combined into both a database and a Geographical Information System (GIS) platform. This unified methodology allowed a cross‐check and analysis of several levels of information, namely hydrotoponymy, hydroclimatology, hydrogeology, structural geology and geomorphology. This perspective led to an assessment of the evolution of the quality of water resources in large urban areas over time. In addition, the role of hydrotoponymical features is presented in order to support the hydrogeological conceptual model for large urbanised areas.     

ARE EU COUNTRIES LESS INTEGRATED THAN U.S. STATES? THEORY AND EVIDENCE*

ABSTRACT A belief that EU integration is incomplete is often predicated on a comparison to U.S. states. Yet, with low barriers to trade and factor mobility between EU countries, is this belief correct? To address this question, we develop three theoretical predictions regarding the distribution of output and factors across members of an integrated economic area with harmonized policies and free movement of goods and factors. Empirical tests strongly support these predictions for U.S. states and 14 EU countries. Constructing a measure of integration, we find that EU integration rose from the 1960s to equal that of U.S. states by 2000.     

HIGH‐RESOLUTION (PIXE) ANALYSES OF CARBONATE DEPOSITS IN A ROMAN AQUEDUCT (FRÉJUS,SE FRANCE): IMPLICATIONS FOR THE STUDY OF PALAEOHYDROLOGICAL VARIABILITY AND WATER RESOURCES MANAGEMENT IN SOUTHERN GAUL DURING THE ROMAN PERIOD*

Urban water was supplied to the Roman city of Forum Julii (Fréjus, southeastern France) for at least 200 years by a 39.4 km long aqueduct, operating in ad 50. Two perennial springs were successively collected, the Foux and the Siagnole, located at the outlet of Triassic and Jurassic karstic reservoirs, respectively. In this study, we performed high‐resolution PIXE (Particle‐Induced X‐ray Emission) measurements of Ca, Si, Fe and Sr concentrations on selected cross‐sections of laminated carbonate sampled along the sidewalls, before and after the connection of the two collection channels. Seasonal variations of water composition, suspended sediment load and discharge are recorded by alternating clear and dark layers, and can be traced by their Sr and Fe contents. On the basis of an annual bimodal high‐discharge regime for the two karstic reservoirs, the concentration measurements allow the derivation of a chronological record (117.5 years) of water supply and maintenance activities for a part of the operational period of the aqueduct. The water level in the channel was mainly controlled by the extent of carbonate deposition and by dredging, repair and maintenance operations rather than by the past hydrological regime of the two springs.     

SEX IDENTIFICATION OF SLAVE SACRIFICE VICTIMS FROM QIN STATE TOMBS IN THE SPRING AND AUTUMN PERIOD OF CHINA USING ANCIENT DNA

Ancient DNA (aDNA) analysis was employed to determine the sex of slave sacrifice victims from Qin State tombs during the Spring and Autumn Period of China. It is difficult to obtain sex information from fragmentary skeleton samples with the aid of skeletal morphology methods. aDNA was extracted from the dentine in selected tooth samples of sacrificial slaves using a modified traditional method, which combines together phenol/chloroform extraction, silicon dioxide adsorption and ultrafiltration concentration. Based on the sequence differences between the amelogenin homologous gene in the X and that in the Y chromosome, a pair of specific primers was designed to identify the sex of the selected samples. In the selected eight typical samples, the aDNA analytical results revealed that three were males and two were females. These findings indicate that molecular sex identification might provide more valuable information for archaeological research on the institution of slave sacrifice in the Spring and Autumn Period of China.     

Biomolecular and micromorphological analysis of suspected faecal deposits at Neolithic Çatalhöyük,Turkey

Suspected coprolites from midden, burial and room fill contexts at Çatalhöyük were analysed by GC/MS and thin section micromorphology. Assessment of sterol biomarkers enabled a distinction between faecal and non-faecal sources for the deposits to be made, with bile acid biomarkers indicating that many of the faecal deposits are human coprolites. The relative lack of ruminant faeces could be due to this material being used as a fuel source. Deposits in burials were observed to contain soil and plant derived sterols rather than their faecal counterparts. Further analysis in thin section enabled identification of associated materials and contents. Diagnostic inclusions such as bone and plant fragments were only present in some of the human coprolites, which were observed to have a very similar morphology to decayed plant remains. This study illustrates the difficulties in distinguishing coprolites in the field and under the microscope, and demonstrates the importance of integrating biogeochemical methods, particularly when such deposits are used as the basis for interpreting human health and diet, and use-of-space in settlements.
