    This paper is an edited version of a written dialogue that took place between the fall of 2008 and the summer of 2009 between a filmmaker (Amelia Bryne) and a cartographer (Se´bastien Caquard) around the issue of representing globalization. In these conversations, we define some of the key means for representing globalization in both mapmaking and filmmaking discussing local/global, strategic/tactical, data/narrative and unique/multiple perspectives. We conclude by emphasizing the potential impact of new media in ushering in hybrid digital products that merge means of representation traditional to filmmaking and cartography

    Intronic Cis-Regulatory Modules Mediate Tissue-Specific and Microbial Control of angptl4/fiaf Transcription

    The intestinal microbiota enhances dietary energy harvest leading to increased fat storage in adipose tissues. This effect is caused in part by the microbial suppression of intestinal epithelial expression of a circulating inhibitor of lipoprotein lipase called Angiopoietin-like 4 (Angptl4/Fiaf). To define the cis-regulatory mechanisms underlying intestine-specific and microbial control of Angptl4 transcription, we utilized the zebrafish system in which host regulatory DNA can be rapidly analyzed in a live, transparent, and gnotobiotic vertebrate. We found that zebrafish angptl4 is transcribed in multiple tissues including the liver, pancreatic islet, and intestinal epithelium, which is similar to its mammalian homologs. Zebrafish angptl4 is also specifically suppressed in the intestinal epithelium upon colonization with a microbiota. In vivo transgenic reporter assays identified discrete tissue-specific regulatory modules within angptl4 intron 3 sufficient to drive expression in the liver, pancreatic islet β-cells, or intestinal enterocytes. Comparative sequence analyses and heterologous functional assays of angptl4 intron 3 sequences from 12 teleost fish species revealed differential evolution of the islet and intestinal regulatory modules. High-resolution functional mapping and site-directed mutagenesis defined the minimal set of regulatory sequences required for intestinal activity. Strikingly, the microbiota suppressed the transcriptional activity of the intestine-specific regulatory module similar to the endogenous angptl4 gene. These results suggest that the microbiota might regulate host intestinal Angptl4 protein expression and peripheral fat storage by suppressing the activity of an intestine-specific transcriptional enhancer. This study provides a useful paradigm for understanding how microbial signals interact with tissue-specific regulatory networks to control the activity and evolution of host gene transcription

    Zones of silence: A framework beyond the digital divide

    There is no doubt that much digital divide work — including connectivity initiatives, technology transfer programs, and other projects — is done with good intention. Yet, as has been widely recognized, the conceptual framework of the digital divide is limiting. The language of the digital divide not only places people into simplistic “have”/“have not” categories, making assumptions about the solution to “information poverty” with little attention to local contexts, its logic also continues a paradigm of development that engages with the global south only at the point of what it “lacks”. I propose a framework, which provides a wider, and more nuanced, lens to look through. It focuses work in ways and in areas consistently overlooked by the digital divide, particularly on the realities, voices, and complexities within its unconnected, “have not” spaces — the zones of silence. Encouraging critical questioning of assumptions and an understanding of local contexts and points of view, a zones of silence framework is a way to broaden the dialogue on global communication and information access beyond a discourse of need, to one of mutual questioning, sharing, and learning. I begin with a brief critique of the digital divide, followed by a definition of this zones of silence framework and how it can help us to see and consider issues differently. I then suggest three areas where work from this perspective might begin

    Broadband adoption in low-income communities

    The social function of the Internet has changed dramatically in recent years. What was, until recently, a supplement to other channels of information and communication has become increasingly a basic requirement of social and economic inclusion. Educational systems, employers, and government agencies at all levels have shifted services online—and are pushing rapidly to do more. Price remains only one factor shaping the fragile equilibrium of home broadband adoption, and library and community organizations fill the gap by providing critical training and support services while under severe economic pressures. Commissioned by the Federal Communications Commission (FCC) to analyze the factors shaping low rates of adoption of home broadband services in low-income and other marginalized communities, this SSRC study is one of the only large-scale qualitative investigations of barriers to adoption in the US and complements FCC survey research on adoption designed to inform the 2010 National Broadband Plan. The study draws on some 170 interviews of non-adopters, community access providers, and other intermediaries conducted across the US in late 2009 and early 2010 and identifies a range of factors that make broadband services hard to acquire and even harder to maintain in such communities

    Internet Infrastructure for All: Time for Canadian Municipalities to Step Up!

    A chapter to appear in For Sale to the Highest Bidder: Telecom Policy in Canada, edited by Marita Moll and Leslie Shade, to be published by the Canadian Centre for Policy Alternatives (CCPA). This version has more extensive footnotes.From the Conclusion: Broadband is an essential infrastructure for the future. As such, it is important not only that it is built, but how it is built as well as who owns and controls it. The Canadian federal government’s policy of relying on “market forces” alone to govern the development of this infrastructure is unwise. One major shortcoming of this policy is that it inadequately addresses existing market power and the disincentives incumbents have to upgrade their infrastructure with fiber and wireless. In their absence, governments at the provincial and municipal level have begun to develop their own broadband networks, making use of newer technologies. These networks, their best practices and business models are still evolving, but they hold promise for the future. Building on existing public governance and ownership models for broadband networks and making a commitment to long-term investment, Canadian municipalities can take a lead in ensuring broadband networks that serve the public interest are built. In effect, by shopping on behalf of their citizens for basic internet services, much as Canadian governments now do with health care, they will be able to craft a much better deal than if consumers are left on their own as individuals to face a few large commercial providers. Such leadership will take political will, particularly in the face of expected stiff resistance from incumbent carriers, but it is of crucial importance for Canadians’ ability to participate in social and economic daily life of the future.The research reported here was conducted as part of the Community Wireless Infrastructure Research Project (CWIRP.ca) with the financial support of Infrastructure Canada.

    The essential internet: digital inclusion insights from low-income American communities

    As the Internet, and broadband in particular, becomes a platform for social and political engagement, researchers investigate more carefully both the factors that drive broadband adoption and the barriers that constrain it. This paper reports on one of the only large-scale qualitative studies of the barriers to broadband adoption in the United States, where 30% of the population lack broadband access. The primary research question asks: how can we qualitatively understand barriers to broadband adoption among low-income communities? The study’s community-based approach, undertaken in four regions of the country, reveals the complex equilibrium of broadband adoption. Drawing from 170 interviews with broadband non-adopters as well as community access providers and other intermediaries, this study finds that price is only one factor shaping home broadband adoption, and that libraries and other community organizations fill the gap between low home adoption and high demand for broadband. These intermediaries compensate for shortages in digital skills that also constitute barriers to adoption in a context where broadband is essential for gaining access to jobs, education, and e-government. These three main findings suggest that low-income people like our research participants are playing roles as actors in an ecology of broadband access games (Dutton et al. 2004). In particular, they are overcoming barriers to being online in order to participate in accessing services and gaining education. This is part of the process of defining broadband as an infrastructure for e-democracy. The paper recommends a renewed focus on factors that sustain home access rather than drive demand, as well as support for community intermediaries in provisioning public broadband access within a context of skill shortages. It recommends further qualitative research to better understand the role of diverse populations in framing the value of broadband access
