Revelations of the World: Transnationalism and the Politics of Perception in Papua New Guinea

Like many over the past century, people in the Yopno Valley of Papua New Guinea have experienced a burgeoning of connections with people across great geographical distances. Building on Benedict Anderson’s well-known discussion of the nation as a “community” imagined in part through the realist framing of newspaper reporting, novels, censuses, and so on, I argue that revelation is an interactional frame central to an emerging global imaginary in the Yopno Valley, one that lies at the heart of Yopno engagements with transnational projects ranging from Christian missionization to environmental conservation and development through Western-style education. In the course of sermons, community meetings, public announcements, and the like, people frequently reveal knowledge of transnational institutions to others, presenting themselves as the necessary mediators between an “out-of-touch” community and a knowledgeable, powerful, and yet obscure world of transnational actors. The world perceived through revelation is one in which persons are defined by their place in a global hierarchy organized by the trajectory of knowledge in circulation, with the Yopno, the last to know, at the bottom. This imaginary, in turn, is reshaping power relations in Yopno communities and influencing people’s understanding of and interest in various transnational projects.Anthropolog

Can the Subaltern Listen? Self-determination and the Provisioning of Expertise in Papua New Guinea

Voice is a major concern in contemporary liberal-democratic politics, one that stresses the political importance of speaking (“giving voice,” “speaking up”). But in the Yopno valley of Papua New Guinea, where NGO and government projects are expanding, people’s sense that they are losing control of their future has led them to worry about their capacity to listen, not their capacity to speak. In largely acephalous villages, people’s self-determination seems particularly threatened by their ignorance of the true nature of their own actions. From a perspective in which the antecedents and the consequences of action are deeply unclear—a perspective stressed in the provisioning of expertise prevalent in political discourse—self-determination hinges on listening and gaining the understanding needed to shape one’s future.Anthropolog

Structural Design using Cellular Automata

Traditional parallel methods for structural design do not scale well. This paper discusses the application of massively scalable cellular automata (CA) techniques to structural design. There are two sets of CA rules, one used to propagate stresses and strains, and one to perform design analysis. These rules can be applied serially,periodically,or concurrently, and Jacobi or Gauss- Seidel style updating can be done. These options are compared with respect to convergence,speed, and stability

Chemical Equilibrium in Collisions of Small Systems

The system-size dependence of particle production in heavy-ion collisions at the top SPS energy is analyzed in terms of the statistical model. A systematic comparison is made of two suppression mechanisms that quantify strange particle yields in ultra-relativistic heavy-ion collisions: the canonical model with strangeness correlation radius determined from the data and the model formulated in the canonical ensemble using chemical off-equilibrium strangeness suppression factor. The system-size dependence of the correlation radius and the thermal parameters are obtained for p-p, C-C, Si-Si and Pb-Pb collisions at sqrt(s_NN) = 17.3 AGeV. It is shown that on the basis of a consistent set of data there is no clear difference between the two suppression patterns. In the present study the strangeness correlation radius was found to exhibit a rather weak dependence on the system size.Comment: 9 pages, 8 figures, submitted to Physical Review

Internal and external scripts in computer-supported collaborative inquiry learning

We investigated how differently structured external scripts interact with learners’ internal scripts concerning individual knowledge acquisition in a Web-based collaborative inquiry learning environment. 90 students from two secondary schools participated. Two versions of an external collaboration script (high vs. low structured) supporting collaborative argumentation were embedded within a Web-based collaborative inquiry learning environment. Students’ internal scripts were classified as either high or low structured, establishing a 2x2-factorial design. Results suggest that the high structured external collaboration script supported the acquisition of domain-general knowledge of all learners regardless of their internal scripts. Learners’ internal scripts influenced the acquisition of domain-specific knowledge. Results are discussed concerning their theoretical relevance and practical implications for Web-based inquiry learning with collaboration scripts

Centrality Dependence of Thermal Parameters Deduced from Hadron Multiplicities in Au + Au Collisions at sqrt{s_{NN}} = 130 GeV

We analyse the centrality dependence of thermal parameters deduced from hadron m ultiplicities in Au + Au collisions at $\sqrt{s_{NN}} = 130 GeV$. While the chemical freeze-out temperature and chemical potentials are found to be roughly centrality-independent, the strangeness saturation factor $\gamma_S$ increases with participant number towards unity, supporting the assumption of equilibrium freeze-out conditions in central collisions

Strangeness counting in high energy collisions

The estimates of overall strange quark production in high energy e+e-, pp and ppbar collisions by using the statistical-thermal model of hadronisation are presented and compared with previous works. The parametrization of strangeness suppression within the model is discussed. Interesting regularities emerge in the strange/non-strange produced quark ratio which turns out to be fairly constant in elementary collisions while it is twice as large in SPS heavy ion collision.Comment: talk given at Strangeness in Quark Matter 98, submitted to J.
