LUSTRE COLOUR AND SHINE FROM THE OLLERIES XIQUES WORKSHOP IN PATERNA (SPAIN), 13TH CENTURY AD: NANOSTRUCTURE,CHEMICAL COMPOSITION AND ANNEALING CONDITIONS*

Lustre is a medieval ceramic decoration, corresponding to a nanostructured thin layer formed by metallic copper and silver nanocrystals embedded in a glass matrix, which required deep knowledge on the part of the artisans with regard to the raw materials used and the kiln conditions. Their empirical knowledge led to the achievement of colourful lustre decorations ranging from reddish to yellowish or even greenish, some of them with a metallic shine with an associated purplish iridescence. Lustre ceramics dating from the 13th century from the Olleries Xiques workshop in Paterna (Spain) have been studied, linking their chemical composition and nanostructure with their colours and shine. Two kinds of nanostructures are found, yellowish lustre decoration constituted by a silver metal–glass nanocomposite, and reddish lustre decoration constituted by metallic copper nanocrystals and copper oxide nanocrystals; in some cases, metallic copper nanocrystals covered with an oxidized shell of CuO and partly Cu₂O have been found. However, even with significant amounts of copper oxide, the lustre still exhibits a copper metal‐like shine. The bluish iridescence observed at a specular angle in the lustre could not be explained completely by means of the chemical composition, and metallic silver nanoparticle light scattering is proposed as a possible explanation.     

What Remains? Reconciling Repatriation,Aboriginal Culture,Representation and the Past

ABSTRACT This paper uses the repatriation and ceremonial reburial of Indigenous remains to La Perouse, an Indigenous community in Sydney, as a lens through which to examine the cultural politics of representation and recognition that are central to contemporary Aboriginal identity construction. The return of the skeletal remains of 21 individuals highlights the role that representative bodies — past and present, individual and organizational — play in engagements between the State and Aboriginal people. Heralded by some as a sincere sign of reconciliation and treated as suspect and misguided by others, the reburial produced diverse responses from both Aboriginal and non‐Aboriginal people alike. Speakers at the repatriation focused on righting the wrongs of the past, reconciliation, and moving forward in cooperation, suggesting the redemptive significance of these events. Among Kooris at La Perouse, debates about community, representation, and belonging expose the ways that Aboriginal people and communities operate through, against, and beyond ‘whitefella’ structures of recognition to define who they are and what their culture is.     

Early prehistoric sedentism and seasonal animal exploitation in the Caribbean lowlands of Colombia

San Jacinto 1 represents a special-purpose settlement that was used by late Archaic foraging groups who logistically moved from base camps to special-purpose camps in order to collect and process subsistence resources at the onset of the dry season in the Caribbean savannas of northern Colombia. Situated in an optimal location for permanent water and seasonal concentrations of dry season subsistence items, the site’s location was part of a logistic strategy in which specific task groups were moved to resources during a short season of availability. Preserved vertebrate and invertebrate faunas at San Jacinto conform to expectations about assemblage ubiquity, richness, and evenness or equitability within the early occupational strata at the site. Specific animals including turtles and fish were pursued, and may have been processed with C3 plants and grasses in ubiquitous earth ovens. Certain local aquatic invertebrates were also procured along with the collection of specific extra-local gastropods.     

NAFTA's Impact on Business Environmental Decision Making

Signing the North American Free Trade Agreement (NAFTA) liberalized trade policy and reduced tariffs between Mexico, the United States, and Canada, but activists opposed to the treaty predicted an environmental disaster. This article seeks to analyze the dynamics of environmental spending and changes in companies' profiles following NAFTA. Our results suggest that these predictions have not come true. Through an econometric model, we explore how 2,438 industries in the 1994–2002 period made environmental decisions and how much they spent on cleanup. Estimates were made with a dynamic panel model using the generalized method of moments (GMM) method. Our results suggest that environmental investment decisions depended on business size, their technological capabilities, sales performance, and the need to comply with the standards required by customers in the international market. The last section explores policies to improve compliance with Mexico's environmental regulations and to develop sustainable, eco‐friendly manufacturing.     

The Impact of Program Design on Enrollment in State Children's Health Insurance Programs

The success of State Children's Health Insurance Programs (SCHIP) in expanding insurance coverage among low‐income children varies considerably across states. Scholars have looked to different program characteristics to explain this variation, but have arrived at disparate conclusions regarding the impact of one of the most significant design choices—the decision to create a new program or to pursue increased child health insurance rates through an expansion of the existing Medicaid program. This study suggests that understanding the impact of programmatic choices requires a more careful consideration of the mechanisms through which these different program designs might influence enrollment than has been offered in previous research. Employing a multilevel governance framework, it suggests that there is a hitherto unexplored indirect impact, where design choices influence administrative behavior, which in turn influences enrollment success in SCHIP programs. It is important to understand the effect of administrative design choices because this is one of the key areas in which states exercise discretion in the implementation of many federal programs.     

Broccoli and Desire

Abstract: Tracing the commodity chain of broccoli from Nashville, Tennessee supermarkets to Maya farmers in highland Guatemala, this paper examines relations of desire and political economic power. We argue that the global broccoli trade is shot through with desires—desires of Western consumers to eat healthy foods as well as desires for Maya farmers to get ahead economically. Such desires simultaneously subvert and sustain the hegemonic constellations that anchor crucial nodes in the international broccoli trade.     

Public Policy Issues and Campaign Strategies: Examining Rationality and the Role of Social Media in a Legislative Election Within a Middle Eastern Context

While most studies from western countries emphasize rationality in electoral behavior, the present study proposes that rationality is also a driver of candidates’ behavior in a non‐Western context. The purpose of the present study is to map campaign content as well as campaign strategies of 214 candidates in the 2015 United Arab Emirates legislative elections. The qualitative analysis showed rational consideration drove the selection of both campaign strategies and public policy positions. Candidates decided to include patriotism and social and economic policy issues in their campaigns to attract votes. In addition, while candidates utilized social meda in their campaigns hoping to maximize their voter outreach, doing so was not necessarily decisive in garnering more votes. Thus, juxtaposed with social meda channels like Twitter, Facebook, Instagram, YouTube, SnapChat, and GooglePlus, traditional campaigning strategies remained very potent.     

Integrating the Strands of Victorian Diversity

This roundtable article provides responses to the other contributions, emphasizing the need for connecting various research strands in Victorian Studies, and considering international aspects. The essay ends with a proposal to take inspiration from the method of microhistorical morphology, forcing the scholar to consider many different contexts.
