GSFC OSTM, Jason-l and TOPEX POD Update
The OSTM (Jason-2) has been in orbit for three years (since June 2008), and the full suite of altimeter data from TOPEX/Poseidon, Jason-I and Jason-2 now span nearly twenty years since the launch of TOPEX in 1992. Issues that affect the stability of the orbits through time and the orbit accuracy include the reference frame, the radiation pressure models for the altimeter satellites and the fidelity of the dynamic force model, including time-variable gravity, as well as the performance of the individual tracking systems. We have conducted detailed analyses of the new ITRF2008 reference frame and find only a small effect on global mean sea level compared to ITRF2005, although we note an improvement in POD quality over the most recent time periods for Jason-2. In the past year we have developed a new time series of orbits for TOPEX/Poseidon, Jason-I, and Jason-2 based on the ITRF2008 reference frame using SLR and DORIS data and for Jason-2 using GPS data. In addition, we have continued to experiment with improvements to the radiation pressure model for the altimeter satellites in particular the Jason satellites since these nonconservative force model errors now rank as the most outstanding source of error on altimeter satellite POD. In the previous (ITRF2005-based) and current (ITRF2008-based) orbits we have relied on a simplified time-variable gravity (TVG) model, derived from GRACE solutions. We have recently experimented with improvements using higher fidelity TVG models (both temporally and spatially) and report on the results. We have computed a time series of GPS-only reduced-dynamic orbits at GSFC, and used these in conjunction with the SLR-DORIS dynamic and reduced-dynamic orbits to assess reference fiame stability with respect to the different tracking systems for both ITRF2005 and ITRF2008. We show through internal (GSFConly) and external comparisons (with other analysis centers) that the radial orbit accuracy for Jason-2 remains at I cm

Globalization from top and below: (re)framing (brazilian) margins in two north-american documentaries
Dissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Comunicação e Expressão, Programa de Pós-Graduação em Letras/Inglês e Literatura Correspondente, Florianópolis, 2010This dissertation analyzes the configuration of socioeconomic and national margins in two contemporary North-American documentaries entirely filmed in Brazil--Favela Rising (Jeff Zimbalist and Matt Mochary, 2005) and Manda Bala (Jason Kohn, 2008). In an attempt to contribute to the research on the representation of Brazil in foreign films, the investigation draws upon concepts such as globalization (Appadurai, 1996; Jameson, 2003), identity (Min-ha, 1997), and difference (Appadurai, 1996; Bhabha, 1996) to approach the documentaries not as fixed representations of a given reality, but as cultural texts that might or not be articulated through the notion of nation. The hypothesis is that the analyzed documentaries are sites for the configuration of margins and, for that reason, are privileged instances to observe the constitution of identities and differences. The conclusion-reached through individual and comparative analyses-is that the documentaries present very distinct articulations of socioeconomic and national margins. On one hand, Manda Bala, through an argumentative and circular structure, reinforces socioeconomic identities circumscribed by a Brazilian national margin. Besides presenting a totalizing portrayal of Brazil, Manda Bala reproduces a colonial gaze that fixes Brazilian society as cannibal, and reinforces the dominant gaze that it seeks to criticize. On the other hand, Favela Rising, through a mainly narrative structure, moves the gaze of national proportions towards the favela of Vigário Geral, in Rio de Janeiro. Less than creating a micro-portrait of Brazil, Favela Rising suggests the existence of social formations beyond national margins, whose political strength exists in its refusal of the negative difference imposed by socioeconomic margins. Another conclusion is that the documentaries present, in an opposite and complementary manner, contradictory forces at play in globalization

Adult experiential learning in short-term study abroad :an heuristic study of the power of place /by Jason Dearden Flora.
Study abroad programs play an important role in the learning pursuits of college and university students. The purpose of this heuristic study was to understand and portray the lived experiences of young adult student participants engaged in a short-term study abroad program in order to explore potential intersections between experiential learning and adult learning theory. With the focus of the study being the Brigham Young University--Idaho European Humanities travel study program, this study sought to describe the essence of experiential learning. As participant-observer, data was collected from 46 student participants during April-July, 2007, in the form of informal conversational interviews, observational field notes, travel journals, and audio-visual materials.;Dual grand tour questions guided this study: (1) What is the essence of experiential learning for young adult student participants engaged in a short-term study abroad program? and (2) How does our understanding of such support adult learning theory? Sub-questions considered include: What is the educative value of a university short-term study abroad program for participants based on their lived experiences? What can participant experiences gleaned during a short-term study abroad contribute to adult learning theory? What experiences can be purposefully provided for student participants in order to contribute to their andragogical growth? What is the overall transferability of experiential learning, based on study abroad, to other life settings?;Through various screening and sampling processes, 11 students were purposely selected as co-researchers. According to phenomenological and heuristic procedures, data was gathered and analyzed to determine emerging themes and categories relative to participant experiences within the context of experiential learning and study abroad. Further connections were made between experiential learning and adult learning theory, specifically andragogy.;Results of the study revealed several essential elements of experiential learning within the context of short-term study abroad. These elements include primary experiences, aesthetic experiences, personal realizations and discoveries, universal realizations, learning connections, and the experience of self-challenge and recognition for change, leading to future personal transformation and growth.;The study concludes with a discussion and proposal of how experiential learning might be further integrated with andragogical principles within the short-term study abroad setting.Thesis (Ph.

DNA fusion gene vaccination mobilizes effective anti-leukemic cytotoxic T lymphocytes from a tolerized repertoire
The majority of known human tumor-associated antigens derive from non-mutated self proteins. T cell tolerance, essential to prevent autoimmunity, must therefore be cautiously circumvented to generate cytotoxic T cell responses against these targets. Our strategy uses DNA fusion vaccines to activate high levels of peptide-specific CTL. Key foreign sequences from tetanus toxin activate tolerance-breaking CD4+ T cell help. Candidate MHC class Ibinding tumor peptide sequences are fused to the C terminus for optimal processing and presentation. To model performance against a leukemia-associated antigen in a tolerized setting, we constructed a fusion vaccine encoding an immunodominant CTL epitopederived from Friend murine leukemia virus gag protein (FMuLVgag) and vaccinated tolerant FMuLVgag-transgenic (gag-Tg) mice. Vaccination with the construct induced epitopespecificIFN-c-producing CD8+ T cells in normal and gag-Tg mice. The frequency and avidity of activated cells were reduced in gag-Tg mice, and no autoimmune injury resulted. However, these CD8+ T cells did exhibit gag-specific cytotoxicity in vitro and in vivo. Also, epitope-specific CTL killed FBL-3 leukemia cells expressing endogenous FMuLVgag antigen and protected against leukemia challenge in vivo. These results demonstrate a simple strategy to engage anti-microbial T cell help to activate epitope-specific polyclonal CD8+ T cell responses from a residual tolerized repertoire
GPS-Based Precision Orbit Determination for a New Era of Altimeter Satellites: Jason-1 and ICESat
Accurate positioning of the satellite center of mass is necessary in meeting an altimeter mission's science goals. The fundamental science observation is an altimetric derived topographic height. Errors in positioning the satellite's center of mass directly impact this fundamental observation. Therefore, orbit error is a critical Component in the error budget of altimeter satellites. With the launch of the Jason-1 radar altimeter (Dec. 2001) and the ICESat laser altimeter (Jan. 2003) a new era of satellite altimetry has begun. Both missions pose several challenges for precision orbit determination (POD). The Jason-1 radial orbit accuracy goal is 1 cm, while ICESat (600 km) at a much lower altitude than Jason-1 (1300 km), has a radial orbit accuracy requirement of less than 5 cm. Fortunately, Jason-1 and ICESat POD can rely on near continuous tracking data from the dual frequency codeless BlackJack GPS receiver and Satellite Laser Ranging. Analysis of current GPS-based solution performance indicates the l-cm radial orbit accuracy goal is being met for Jason-1, while radial orbit accuracy for ICESat is well below the 54x1 mission requirement. A brief overview of the GPS precision orbit determination methodology and results for both Jason-1 and ICESat are presented
Relations between acoustic and articulatory measurements of /l/
Variation in the production of English /l/ has received significant study. It has been characterized in terms of categorical allophones, in terms of acoustic properties, and in terms of articulatory timing. Using a parallel corpus of acoustic-articulatory data from two speakers of American English, this study looks at the relations between acoustic and articulatory measurements of /l/ across words in corpus of read speech. We find significant negative correlations between F1 and tongue tip height and significant positive correlations between F2 and tongue body retraction. Additionally, we find that the relative timing of tongue tip and tongue back gestures in our data are consistent with past work on positional variants of /l/
