    Bridging the ICT4D Design-Actuality Gap: “Human ATMs” and the Provision of Financial Services for “Humble People”

    Most challenges in ICT for development (ICT4D) projects can be related to differences in perceptions of systems developers and their actual users. Such design-actuality gaps exist both because designers take an uninformed stance towards the user context, and also because problems that ICT4D projects address are nested in systems whose interplay is nearly impossible to predict. Although gaps are inevitable, users are not passive recipients whose only choices are to accept shortfalls in design or reject ICT4D technologies. Rather, users may act to remedy shortfalls through system work-arounds. In this paper we investigate the design use gap in the Brazilian correspondent banking model, an ICT4D project in which local small businesspeople interact with social, financial, government, and technical systems to provide financial services mostly for poor populations. Our findings suggest that correspondents’ acts to alter the financial and social systems proved sufficient to permit success of the project. Our results point to the importance of taking into account user actions and the separate roles of individual systems when designing ICT4D projects and theorizing their performance

    WISE/NEOWISE observations of Active Bodies in the Main Belt

    We report results based on mid-infrared photometry of 5 active main belt objects (AMBOs) detected by the Wide-field Infrared Survey Explorer (WISE) spacecraft. Four of these bodies, P/2010 R2 (La Sagra), 133P/Elst-Pizarro, (596) Scheila, and 176P/LINEAR, showed no signs of activity at the time of the observations, allowing the WISE detections to place firm constraints on their diameters and albedos. Geometric albedos were in the range of a few percent, and on the order of other measured comet nuclei. P/2010 A2 was observed on April 2-3, 2010, three months after its peak activity. Photometry of the coma at 12 and 22 {\mu}m combined with ground-based visible-wavelength measurements provides constraints on the dust particle mass distribution (PMD), dlogn/dlogm, yielding power-law slope values of {\alpha} = -0.5 +/- 0.1. This PMD is considerably more shallow than that found for other comets, in particular inbound particle fluence during the Stardust encounter of comet 81P/Wild 2. It is similar to the PMD seen for 9P/Tempel 1 in the immediate aftermath of the Deep Impact experiment. Upper limits for CO2 & CO production are also provided for each AMBO and compared with revised production numbers for WISE observations of 103P/Hartley 2.Comment: 32 Pages, including 5 Figure

    The James Webb Space Telescope Mission

    Twenty-six years ago a small committee report, building on earlier studies, expounded a compelling and poetic vision for the future of astronomy, calling for an infrared-optimized space telescope with an aperture of at least 4m4m. With the support of their governments in the US, Europe, and Canada, 20,000 people realized that vision as the 6.5m6.5m James Webb Space Telescope. A generation of astronomers will celebrate their accomplishments for the life of the mission, potentially as long as 20 years, and beyond. This report and the scientific discoveries that follow are extended thank-you notes to the 20,000 team members. The telescope is working perfectly, with much better image quality than expected. In this and accompanying papers, we give a brief history, describe the observatory, outline its objectives and current observing program, and discuss the inventions and people who made it possible. We cite detailed reports on the design and the measured performance on orbit.Comment: Accepted by PASP for the special issue on The James Webb Space Telescope Overview, 29 pages, 4 figure

    This report details the differences in information dissemination among different types of workers at the University of Texas at Austin. In total, 903 surveys were distributed among employees in the fall of 2008. The majority of questions addressed the following topics: � Channels used to send and receive information � Information received/desired about particular campus issues (benefits, parking, safety/security, organizational policies, and workgroup training. � Computer access and perceived skills � Languag
