Changes in starch grain morphologies from cooking

One of the three main plant microfossils, starch grains are increasingly used as markers of diet, plant domestication, tool use and site organization, because their morphology and features provide a means to identify the plant that produced them. However, starch grains are susceptible to damage when they are exposed to heat in the presence of water, as in cooking. We documented the changes that occur in the starch grains of 10 domesticated plant species due to exposure to different cooking methods, in order to better understand how cooking alters the appearance of the grains, and if these cooking methods might be identifiable in the archaeological record. Our results show that some cooking methods produce unique, identifiable damage on some types of plant starches, but generally each plant species reacts uniquely to cooking. In order to record the changes for each plant species, we have created a database, available at (http://www.osresearch.net/∼hollyf/starchdb/index.cgi), to which registered users can add their own images of cooked starch grains.     

American home: Predatory mortgage capital and neighbourhood spaces of race and class exploitation in the United States

Predatory home mortgage lending has become a central concern for housing research, public policy and community activism in US cities. Regulatory attempts to stop abuses, however, are undermined by claims that ‘predatory’ cannot be defined or distinguished from legitimate subprime lending, and claims that the industry performs a public service by meeting the needs of low‐income, high‐risk consumers (many of them racially marginalized) who would have been denied credit in previous years. We evaluate these claims in historical‐geographical context, drawing on David Harvey's theory of class‐monopoly rent to analyse what is new (and what is not) in contemporary financial exploitation. We use a mixed‐methods approach to (1) provide econometric measures of subprime racial targeting and disparate impact that cannot be blamed on the supposed deficiencies of borrowers, (2) qualitatively assess the rationale for judging particular subprime practices and lenders as predatory, and (3) trace the connections between local practices and transnational investment networks. The fight against predatory lending cannot succeed, we argue, without a renewed analytical and strategic emphasis on the class dimensions of financial exploitation and racial‐geographical discrimination.     

Pencils and Pixels: Drawing and Digital Media in Archaeological Field Recording

Within the context of a growing emphasis on digital recording, what is the place of analog drawing in archaeological fieldwork? In this article, we situate the increased application of digital drawing methods by providing several historical examples of archaeological field drawing in British archaeology to demonstrate the connection between understanding the archaeological record and illustration. Given this background of analog archaeological recording, we then explore the current state of archaeological field drawing and the affordances of digital illustration for recording and interpreting the archaeological record, review literature in architecture and design regarding the cognitive function of analog and digital drawing, and discuss the possible future implications of born-digital or paperless archaeology.     

PLACE ELASTICITY: EXPLORING A NEW CONCEPTUALIZATION OF MOBILITY AND PLACE ATTACHMENT IN RURAL AMERICA

Migration and place attachment are often coupled within the migration decision‐making literature with the underlying assumption that individuals with strong place attachments are less likely to migrate than individuals with weaker ties to place. As communication technologies have improved, however, new forms of place attachment and connections between individuals and places are evolving. We introduce the concept of place elasticity as a new conceptualization of place attachment made possible by innovations in communication and transportation technologies. Place elasticity allows individuals to live in distant locales while maintaining close interaction with a particular place. We explore this concept with questionnaires and interviews from a sample of individuals from rural Appalachian counties in eastern Kentucky. Rural residents of this region have been noted for their strong place attachments and connections to their home county. Based on our questionnaires and interviews from family reunions we propose that place elasticity has three distinct characteristics: portability, strong place bonds, and permanence and that these traits allow individuals to remain connected to home counties and family, thereby allowing migration and settlement in distant locations with minimal loss of connectedness.
