"A Jedi like my father before me": Social identity and the New York Comic Con [symposium]
No full textFew venues exist for adults to play dress-up, with Renaissance festivals, comic and other media conventions, and live-action role-playing games comprising the bulk of these venues. This sort of behavior is expected of people in their formative years—children and teenagers—where they try on and receive feedback about their selves. What might be the reasoning behind the behavior of adults doing so, especially after primary socialization has occurred

Culturally mapping universes: Fan production as ethnographic fragments
No full textEthnography has played a large role in fan studies; thus, any mention of ethnography in conjunction with fan studies is unsurprising. Ethnography's use of performance studies and the subsequent emphasis on embodied practice, however, creates new intersections between ethnography and the fan. Thus far, the fan has been relegated to the position of ethnographic subject. We argue here that the fan can be viewed as an ethnographer proper, mining ethnographic fragments from the source material in order to explore and explain the workings of a fictive culture within a fictive universe. The nature of fan production when viewed in such a manner is highly dramaturgical in nature. To account for this within the ethnographic framework, we use the term ethnodramaturg to describe how the fan works within a fictive universe to study and create dramatic story lines based within that world. Performatively, the fan enacts the ethnographer's in-betweenness. Both fan and ethnographer are not of the culture and yet not not of the culture they explore and attempt to explain. In ethnography, this means the subject is simultaneously observed and created through the use of ethnographic objects, or fragments. These fragments are then displayed or dramatically deployed independently of that source. Fan-produced media, having been excised from the source material, can be viewed as ethnographic fragments. Fans, as ethnodramaturgs, carve out discrete objects of the fictive world for study and link them together in a performative story line

Analysis of a Class of Parallel Matrix Multiplication Algorithms
No full textPublications concerning parallel implementation of matrix-matrix multiplication continue to appear with some regularity. It may seem odd that an algorithm that can be expressed as one statement and three nested loops deserves this much attention. This paper provides some insights as to why this problem is complex: Practical algorithms that use matrix multiplication tend to use different shaped matrices, and the shape of the matrices can significantly impact the performance of matrix multiplication. We provide theoretical analysis and experimental results to explain the differences in performance achieved when these algorithms are applied to differently shaped matrices. This analysis sets the stage for hybrid algorithms which choose between the algorithms based on the shapes of the matrices involved. While the paper resolves a number of issues, it concludes with discussion of a number of directions yet to be pursued. Corresponding Author, Phone: (512) 471-9720, Fax: (512) 471-8885. ..
PLAPACK: Parallel Linear Algebra Libraries Design Overview
No full textSubmitted to SC97 Corresponding Author: Robert van de Geijn Department of Computer Sciences The University of Texas at Austin Austin, TX 78712 (512) 471-9720 (office) (512) 471-8885 (fax) [email protected] Abstract Over the last twenty years, dense linear algebra libraries have gone through three generations of public domain general purpose packages. In the seventies, the first generation of packages were EISPACK and LINPACK, which implemented a broad spectrum of algorithms for solving dense linear eigenproblems and dense linear systems. In the late eighties, the second generation package called LAPACK was developed. This package attains high performance in a portable fashion while also improving upon the functionality and robustness of LINPACK and EISPACK. Finally, Since the early nineties, an effort to port LAPACK to distributed memory networks of computers has been underway as part of the ScaLAPACK project. PLAPACK is a maturing fourth generation package which uses a new, more a..
Optimizing the performance of streaming numerical kernels on the IBM Blue Gene/P PowerPC 450 processor
No full textSeveral emerging petascale architectures use energy-efficient processors with vectorized computational units and in-order thread processing. On these architectures the sustained performance of streaming numerical kernels, ubiquitous in the solution of partial differential equations, represents a challenge despite the regularity of memory access. Sophisticated optimization techniques are required to fully utilize the CPU. We propose a new method for constructing streaming numerical kernels using a high-level assembly synthesis and optimization framework. We describe an implementation of this method in Python targeting the IBM® Blue Gene®/P supercomputer's PowerPC® 450 core. This paper details the high-level design, construction, simulation, verification, and analysis of these kernels utilizing a subset of the CPU's instruction set. We demonstrate the effectiveness of our approach by implementing several three-dimensional stencil kernels over a variety of cached memory scenarios and analyzing the mechanically scheduled variants, including a 27-point stencil achieving a 1.7× speedup over the best previously published results. © The Author(s) 2012

Understanding how condition varies among age and sex cohorts and temporally can inform habitat management during the post- and pre-breeding period. We examined changes in body composition and molt of three waterfowl species migrating and wintering in managed moist-soil units in east central Texas and determined the influence of season, age, and sex using Analysis of Variance. We examined age, sex, and season effects on body condition indices (body mass divided by wing chord) using mixed-effects models and determined the influence of molt score on body condition using linear regression. For specimens collected from 2004–2007, we found differences in body composition among age and sex groups for Blue-winged Teal (Spatula discor), a migrant through this study area, and for Green-winged Teal (Anas crecca), and Northern Shoveler (Spatula clypeata), which are wintering species. We found a mid-winter decline in body condition for Green-winged Teal. Blue-winged Teal were in worse condition in spring than in fall, which could be due to differences in energy accumulation prior to departure to wintering grounds in fall and post-arrival in spring. We did not find an effect of season for Northern Shoveler. For all species, adults were in better condition than juveniles. Molt score was greatest in late-winter for all species combined (x̄ = 11.60, SE = 2.45). We did not find an effect of molt score on body condition for any species. Wintering waterfowl in east central Texas appear to be in good condition and did not show molt-induced stress during the migratory and wintering periods. Changes in condition among specimens and across seasons indicate that there should be consideration in the timing and quality of management in regional approaches to moist-soil management for migrating and wintering waterfowl
