Koan amphorae from Halasarna – investigations in a Hellenistic amphora production centre

Ceramic amphorae have been the most popular transport and storage containers for a large variety of liquid and solid products. The amphorae of the present study were used as transport containers for wine from the island of Kos (East Aegean). Therefore, they had to fulfil certain requirements in terms of mechanical strength and toughness but also in terms of standardization of vessel size and shape. An assemblage of amphora fragments from the excavation of ancient Halasarna, an amphora production centre, will be presented. The ceramics were studied by means of their chemical and mineralogical composition and fabric. Furthermore, their material properties were measured and their mechanical performance was simulated in computer models.     

Phylogeographic analysis of barley DNA as evidence for the spread of Neolithic agriculture through Europe

Results of analyses of the photoperiod response gene (PPD-H1) and simple sequence repeats (SSRs) in modern landraces of cultivated barley were used as evidence for the mechanism of agricultural spread in Neolithic Europe. In particular, we explored the usefulness of considering adaptive genes as indicators of past selective pressures acting on crops, during their spread through Europe. In some areas, such as the Alpine region, Britain and Scandinavia, we have evidence to suggest that the adaptation of crops to certain climatic conditions may have contributed to the timing of agricultural spread. At the northern fringes of Europe, and in higher altitude locations in central Europe, the introduction of more suitably adapted cereals may have facilitated successful agriculture to trigger agricultural expansion. This research opens up the possibility of investigating other genetic adaptations to climate, which would permit a fuller evaluation of the relative contributions of climate/crop and forager/farmer interactions in the process of agricultural spread.     

Building economies from the bottom up: (mis)representations of poverty in the rural American Northwest

This paper examines interconnected processes of economic restructuring and representations of poor subjects that rely on imaginaries of race, ethnicity, class and rural space. We argue that poverty and privilege are mutually produced and so we focus on the representational practices of White leaders in persistently poor counties across the American Northwest. We draw from case study research to understand region-wide material and discursive processes that are contributing to economic distress and social marginalization. We interrogate the range of representational practices that White leaders employ to explain, deny and/or racialize poverty in their communities. We also draw attention to how poverty emerges from the intersection of political, economic and cultural processes operating across a range of scales and sites. We further analyze how representations of the poor and poverty rest on a host of imaginary landscapes about who belongs, who is an outsider and who has a right to a place and its services. We argue that these representations serve to invigorate neoliberal policies and silence a more critical debate about poverty in the USA.     

Public Presidential Appeals and Congressional Floor Votes: Reassessing the Constitutional Threat

The assertion that public appeals by presidents can create electoral threats to noncompliant members of Congress is central to arguments about the value of "going public" as a legislative strategy. Although recent scholarship suggests a link between popular presidential rhetoric and the likelihood of bill passage, researchers have yet to examine the impact of public presidential appeals on individual legislators. This study examines the logic of electoral threats imposed by going public. We test whether a president's going public with increased intensity leads individual members of Congress to increase their support for presidential preferences on congressional floor votes. We employ several measures to assess the intensity of presidents' public appeals, including domestic speeches, nationally televised addresses, and speeches in legislators' home states. Several logistic regression models are tested to determine whether congressional support for presidential preferences on the floor is influenced by the interaction between members' electoral vulnerability and presidents' use of popular appeals. The findings suggest that presidential speechmaking has very little impact on the likelihood that members of Congress will support the president's position on roll call votes. We argue that this suggests a necessary revision of criticisms of the "rhetorical presidency." Public presidential appeals do not seem to present a considerable threat to a constitutional order that is predicated on congressional autonomy and deliberation.
