Ceramic diversity,random copying,and tests for selectivity in ceramic production

This paper examines the evidence for selective reproduction of ceramic types based on their evolving frequency distribution, and on correlations of the abundance of types with underlying functional characteristics. How can we tell if a variant has been preferentially selected or discriminated against, and become more or less frequent than would be expected under pure drift (i.e. random copying, with the compounding over time of proportionate sampling error)? We examined a database of Hittite ceramic bowl types from two successive Phases of occupation of the Upper City of Bo?azköy–Hattusa, capital of the Hittite empire and the largest Bronze Age settlement in Turkey. We applied two tests used in genetics to assess departures from neutrality, to assess selectivity in rates of reproduction of ceramic bowl types (the Ewens-Watterson and Slatkin's Exact tests). We also examined the effects of ceramic fabric and vessel dimensions on changes in vessel abundance between the two Phases, using regression analysis. We found that while the frequency distribution of rim sherds did not in itself enable us to reject the null hypothesis of random copying, closer examination of the characteristics of these types enabled us to recognize latent dimensions of functional variability (including ware type and bowl diameter) that had demonstrably been the subject of selective decision-making by the potters. The present case study suggests that we should be wary of applying the neutral model from genetics uncritically in archaeology, because it is much harder to prove that the cultural traits whose frequencies are being modelled are genuinely functionally equivalent (as that model requires).     

Effect of organic and inorganic consolidation agents on Tlaltecuhtli monolith

A huge monolithic piece corresponding to the first years of the sixteenth century has been discovered in Mexico City. It represents the earth goddess Tlaltecuhtli. The preservation of such a magnificent piece is imperative. Therefore, the surface has to be characterized and the interaction of consolidants with the rock has to be understood.Some of the consolidation methods are impregnation of the mineral with nopal or silicic acid derivatives. In this work we compare the physico-chemical effects of organic and inorganic consolidants. Original and impregnated samples are characterized with a series of original techniques: X-ray diffraction, nuclear magnetic resonance, nitrogen adsorption and small angle X-ray scattering. Fractal dimension, specific surface area and pore size distribution clearly differentiated the samples. The organic materials, nopal gum or slobber, cover the mineral particles with a smooth layer. The KSE solutions react and lead to microporosity.     

Physiological optics, cognition and emotion: a novel look at the early work of Wilhelm Wundt

The German physiologist Wilhelm Wundt, who later founded experimental psychology, arguably developed the first modern scientific conception of emotion. In the first edition of Vorlesungen über die Menschen- und Thierseele (Lectures on human and animal psychology), which was published in 1863, Wundt tried to establish that emotions were essential parts of rational thought. In fact, he considered them unconscious steps of decision-making that were implied in all processes of conscious thought. His early work deserves attention not only because it is the attempt to conceptualize cognition and emotion strictly from a neural point of view but also because it represents the very foundation of the debate about the nature of emotion that revolved around William James' theory of emotion during the 1890s. However, this aspect of his work is little known because scholars who have analyzed Wundt's work focused on his late career. Furthermore, historical analysis interpreted Wundt's work within a philosophical framework, rather than placing it in the context of German medical and physiological research in which it belongs. In addition, Wundt's early works are hardly available to an English speaking audience because they were never translated.     

Towards a Living Archive: Making Multi Layered Research Data and Knowledge Generation Transparent

ABSTRACT

Çatalhöyük was first discovered as one of the earliest urban settlements in the late 1950s and excavated by James Mellaart between 1961 and 1965. The 9000-year-old town in central Turkey rapidly became famous internationally due to the large size and dense occupation of the settlement, as well as the spectacular wall paintings and other art that were uncovered inside the houses. Since 1993, under the direction of Ian Hodder, research at Çatalhöyük has pioneered a reflexive approach to archaeological practice, in which information is permanently open to reinterpretation by both scholars and the public. This approach acknowledges the mutual dependence of knowledge and the underlying research, to which end the Çatalhöyük Project decided to make its records available via the Web and to invite public comment since its onset. After 25 years of excavation, the project’s digital assets now amount to close to 5TB, including formal textual and numeric records, freetext documents, audiovisual materials, and a comprehensive collection of spatial data. The reflexive method, or ‘documentation of the documentation process,’ adds a separate layer of information that specifies how data have been gathered, and facilitates critique, understanding, and the evolution of knowledge.

In this paper we lay out our vision of an interactive archive that provides access to the multi layered information contained in this massive amount of data and how web technological advances have been incorporated into the digital data management at Çatalhöyük. Ultimately, the goal is to support an interdisciplinary process of assembling data into arguments on the basis of multiple lines of evidence. The ‘Living Archive’ will enable intuitive engagement across the entire variety of research, making use of the rich reflexive information stored with the data. The results of new analyses can in turn be reintegrated with the already existing data. The application will use open standards so that the knowledge gathered at Çatalhöyük can be linked with other projects that follow similar publication procedures based on the semantic web approach.     

The After School Routines of Literature-Devoted Urban Children

This paper discusses the out of school routines of a group of ‘literature-devoted’ children of the city of Madrid (Spain). The children and families were recruited for the study at a library, a children's bookstore and a puppet show in a park. Participants provided information on their weekly routines through several procedures: surveys, photographs of their daily lives, interviews based on the photographs and interviews with parents. We develop a spatially based model that allows us to identify four styles of activity in children's out of school lives: homebound children, non-scheduled children, outdoor and scheduled children, and fully scheduled children. Our results suggest that there is significant diversity in the ways in which children's after-school time is organized, even within a middle-class and socially homogeneous sample as the one in this study. Also, the range of activities our participants engage in seems to contradict current portraits of Western urban children's lives as constrained.     

Confusing the grid: spatiotemporalities,queer imaginaries,and movement

Mediating between queer theory's privileging of time as actor and geographic emphases on material spaces and identities, this article engages feminist geographies and the work of Deleuze and Guattari to understand the implications of time and space as imagined, or actors' spatiotemporal imaginaries. We draw on Massumi's metaphor of the ‘grid,’ which sediments ways of seeing self and other and logics for action and interaction. The grid incites imaginaries of time as active and space as passive, which evoke past, present, and future, offering coordinates for locating identities. Focusing on spatiotemporality, we conduct a discourse analysis of interviews with two Chilean lesbian-feminist activists, focusing on (1) overtly spatial and temporal dimensions (nation, region, history), (2) the constitution of lesbian space and identity (identity, visibility, consciousness, and community), and (3) oppositional entities that stabilize lesbian identity and space (men, gay men, feminists, universities, and queer). We demonstrate how the activists' imagining of Chile as a space with a linear history with a fixed past and present directs their actions to a particular future of pre-given positions. Nonetheless, we point to moments of disidentificatory movement that returns analytic attention to process, creation, and the open potentiality of movement. The politics of spatiotemporal imaginaries offers activists, geographers, and queer theorists ways of narrating sexualized subjects and politics that are not repetitive of identitarian debates, history as necessary sequence, or spaces as material.     

The World Bank–United States–Latin American Triangle: The Negotiations with Socialist Chile, 1970–1973

This paper sheds light on the largely unknown negotiations between Chile and the World Bank (WB) during the presidency of Salvador Allende (1970–1973). The prevalent understanding of the WB's involvement in Latin America portrays the Bank as a loyal ally of the U.S. government and as an institution with the power to impose its views on its borrowers. Yet, an in-depth analysis of previously unexamined primary sources demonstrates that rather than reflecting a dynamic in which the relationship was between Washington and the WB on the one hand, and Chile on the other hand, these relations constituted a WB–U.S.–Chile asymmetric triangle. Despite profound ideological discrepancies, multiple pressures, and constraints, Allende's government and the WB conducted high-ranking negotiations that challenged the U.S.-promoted economic embargo against Chile. The examination of this counterintuitive relationship sheds new light on Allende's positioning in the international arena and on the functioning of the World Bank, thereby providing a unique prism through which to reconsider dichotomist perceptions of the Cold War in Latin America.
