Wikipedia : <em>Informationspublicering på Internet ur ett genus- och maktperspektiv</em> / : <em> </em>

Samuelsson, Karolina, Lindkvist, Annika January 2007 (has links)
<p>This essay is about publishing on the Internet and aims to understand the differences between publishing information on the webpage Wikipedia (Swedish version) in contrast to other information pages on the Internet, for example blog, discussion pages, homepages etcetera. The study is based upon an article which described that 90% of the information publishers at Wikipedia belongs to a small elite of white, western, well educated men between the age of thirty to thirtythree. This study examines why people who does not belong to this heteronormativity publish information in other Internet places but not at Wikipedia.Wikipedia is an open source site, where anyone can publish and are even encouraged to do so and is often described as an utopian dream of the digital democracy, so why don´t people express themselves on Wikipedia? The method is based on two discussion groups, which are compared and analyzed. The study is based upon theoretical competence within feminist theory and conceptions such as intersectionality, heteronormativity and digital divide as well as theories about digital devices and social order. The analyses concluded that Wikipedias structure restrains people from contributing with information on the site, that is understand to be associated with true and objective information and prestige. It is also compared to the printed encyclopedia which also strengthens this understanding. And when people publish information in other coherences it is based upon their own understanding, and this requirement for true and objective information at Wikipedia hinder many.</p>

Kampen om kunskap: Vem bestämmer vad kunskap är och vem äger den? : En textanalys av WIPOs Development Agenda och Draft Treaty on Access to Knowledge

Löfberg, Anna-Lena January 2008 (has links)
<p>Uppsala universitet The aim of this master’s thesis is to investigate, through text analysis, the role of copyright in development, with particular interest of how the concepts <em>knowledge </em>and <em>access to knowledge </em>are used in <em>Access to Knowledge Draft Treaty </em>and <em>WIPO Development Agenda</em>. The definition of the concept knowledge, as it is used in copyright, is based in a Western historical and philosophical context and therefore excludes knowledge created in another type of society. The consequences of this exclusion have effects on development. Further it is stated that knowledge according to the global copyright scheme will be reduced to a commodity, which will have consequences not only in societies in the global South. The difficulties in achieving <em>access to knowledge </em>in the global copyright regime are investigated. The flexibilities contained in the Berne Convention and the TRIPS Agreement are limited in scope and difficult to maintain. Exclusion from access to knowledge affects development and deepens inequalities both within countries and globally.</p>

Bridging Digital Poverty: Adoption of Information and Communication Technologies at Community Technology Centers in the Dominican Republic

Prado, Paola 10 August 2009 (has links)
Globalization and the rise of the Information Society pose many challenges to developing nations. In adherence to the Millennium Development Goal of digital inclusion, the government of the Dominican Republic established a national program of community technology centers, or telecenters, that aim to promote digital literacy among the poor. This study examined how these telecenters promote the adoption of information and communication technologies (ICTs) and tested whether perceived structural factors, individual motivation or demographics predict adoption. Results from a survey conducted in the rural villages of El Seybo, Navarrete, and Oviedo confirm that telecenter users learn how to use information and communication technologies as a resource for information about civic life, entertainment, and professional development. The study concludes that telecenters can succeed in decreasing digital poverty, provided issues of sustainability are addressed with consistent and continued government funding and support. The field of information and communication technologies for development (ICT4D) is in its infancy and has yet to develop strong methodological or theoretical standards. This study of ICT adoption and telecenter use in rural areas of the Caribbean contributes empirical evidence to the literature of this emerging discipline.

DIGITAL DIVIDE: UNA RILETTURA CRITICA DEL TERMINE, DEL FRAMING IDEOLOGICO, DELLE POLICIES

CARLO, SIMONE 26 June 2009 (has links)
La letteratura sul digital divide ha fatto negli ultimi anni importanti passi in avanti: una velocità, quella dell’evoluzione del concetto di divario digitale, sorprendente, se si pensa che il termine nasce poco più di dieci anni fa (DiMaggio et al. 2004). Ancora più interessante è la duttilità del termine, che si è trasformato in un vero e proprio discorso, quasi in termini foucaultiani, assorbito da governi, istituzioni, associazioni, aziende. La flessibilità del termine sembrerebbe avere svuotato il concetto stesso di digital divide: se da una parte la letteratura e la riflessione accademica si sta progressivamente allontanando dal termine (Warschauer, 2003), dall’altra l’azione politica l’ha fatto proprio, perdendo sempre più aderenza col dibattito teorico in corso (van Dijk 2005; Barzilai-Nahon 2006). L’ambiguità del termine digital divide pone seri problemi circa la definizione della issue: alcuni studiosi (Compaine 2001) hanno definito il digital divide come un problema di semplice diffusione tecnologica. Tale impostazione, ampiamente superata dalla letterature accademica, è stata invece convintamente adottata dagli strategy makers istituzionale e politici, con effetti spesso contraddittori e discutibili sulle modalità di diffusione e adozione delle ICT tra la popolazione. E’ come se di fronte all’evoluzione del dibattito accademico, i soggetti pubblici non abbiano avuto la capacità (e la volontà politica) di far contestualmente evolvere le politiche adottate verso un avvicinamento al tema del divario di competenze. Al contrario, le strategie degli attori pubblici (privati e istituzionali) sembrano in alcuni casi essere ancora legate a interpretazioni, valori culturali, miti, retoriche tipiche della nascita dell’era digitale (Mosco 2004). In particolare, le istituzioni sono impegnate in un continuo processo interpretativo sul ruolo delle tecnologie (della comunicazione) nella società: ciò che sembra emergere dall’analisi dei principali documenti prodotti dalle istituzioni europee e statunitensi sul digital divide e sullo sviluppo della Società dell’Informazione, è la costruzione di un’ideologia di stampo diffusionista e determinista, all’interno della quale le tecnologie digitali (con Internet in testa) sono in grado di determinare una cesura storica e hanno la capacità di offrire alla società delle opportunità di sviluppo rivoluzionarie. Nonostante tale processo di costruzione narrativa delle opportunità sociali delle ICT, le concrete politiche di riduzione del divario digitale sembrano seguire un’altra strada (Milner 2006). La ricerca, dopo una panoramica sull’evoluzione del concetto di digital divide (Iannone 2007), affronta la più recente letteratura sul tema delle disuguaglianze digitali (Newholm et al. 2008; Sartori 2006; DiMaggio et al 2004), inserendola nella più ampia riflessione sulle disuguaglianze economiche e sociali del mondo contemporaneo (Gallino 2000; Milanovic 2007) e relazionandola con un’overview delle strategie e politiche pubbliche e private di riduzione del divario numerico, in particolare nell’Unione Europa e negli Stati Uniti. L’obiettivo finale del paper è dunque evidenziare il pericoloso scollamento tra l’essenza delle disuguaglianze digitali (la cui comprensione è possibile solo se inserita in una più ampia riflessioni sulle disuguaglianza societarie) e la loro discorsivizzazione, rappresentazione e messa in forma operata dai soggetti e dalle istituzioni che si sono assunti la responsabilità di messa a punto delle strategie di superamento del divario digitale (Carlo 2008). La tesi è che, nel processo di discorsivizzazione del digital divide, i soggetti pubblici abbiano costruito un apparato retorico in grado di offrire una rappresentazione del problema lontana dalla reale natura del fenomeno: il digital divide ha assorbito retoriche e miti del ciberspazio e della società contemporanea, trasformando tali miti in un’azione politica in molti casi inadeguata, inefficacia, fuori obiettivo (Colombo – Carlo 2006a). Sembra di essere di fronte in alcuni casi a una vera e propria azione mistificatoria: si discorsivizzano azioni politiche di riduzione del digital divide legate a un auspicato processo di sviluppo sociale e culturale (determinato dalle ICT) per perseguire, in verità, obiettivi di carattere puramente economico. Forse solo attraverso un’azione di disvelamento di tale mistificazione, è possibile riconoscere le vere politiche di riduzione del divario digitale che sono tali solo se inserite in una più ampia riflessione (e azione) attorno alla crescita delle disuguaglianze nella società globale, informatizzata, in rete (Colombo – Carlo 2006b). Il rischio è che tali azioni, altrimenti, siano semplicemente legate a dimensioni economicistiche di efficienza e di crescita, pericolosamente controproducenti per lo sviluppo di società più giuste (Feenberg 2002; van Dijk 2006). / In the recent years, the literature about digital divide makes an important breakthrough: the evolution of concept of digital divide it has been very quick, in particular if is related with the relative youthfulness of the term, that born only ten years ago (DiMaggio et al. 2004). Even more interesting is the “pliability” of the term: it’s seem to be transformed in a kind of discourse, near in Foucault’s concept, premise by governments, institutions, associations, companies. The flexibility of the term seems has transform (near empty out) the concept of digital divide: if on the one hand the academic reflections are gradually moving away from the term (making more complex the concept, Warschauer, 2003), on the other hand the political action still “use” the term, without understand the theoretical debate in progress and the changing of meaning of the concept (van Dijk, 2005; Barzilai-Nahon, 2006). Maybe only through an action of “unmasking” of this kind of mystification could be possible to recognize the true (or, the more efficient, useful, comprehensive) policies of reduction of the digital divide. Only if this policies are combined with a broader reflections (and actions) about the rising of inequality in the global, digital, network society, the effect of these measures of government will be visible. The risk is that these measures, without a deeply consideration about the morphology, characteristic, structurally unequal of contemporary society, are linking only with economic dimension of efficiency and development. This kind of “use” of digital divide term in a frame of economical policy could be very dangerous and counterproductive for the improvement of more equitable societies (Feenberg 2002, van Dijk, 2006). This paper, after a overview about the evolution of the concept of digital divide (Iannone, 2007) , face the most recent literature about digital inequality (DiMaggio, P., Hargittai, E., Celeste, C., and Shafer, S. 2004): on one side it frames the literature of digital divide in a broader reflection about economic and social inequality in the contemporary world (Gallino 2000; Milanovic 2007), on the other side it wants to related this literature with an overview of policy and strategy public and private for the reduction of digital divide, in particular in EU and USA (Milner, 2006). The aim of the paper is to stress the dangerous separation between the essence of digital inequalities and their discoursivization, representation and “shaping” made by the subjects that have taken the responsibility or have the role to manage and ideate strategies for fall digital divide.

Exploration of Newcomers’ Access to Internet Literacy

Ascenuik, Catrina 05 January 2012 (has links)
The purpose of this study was two fold: (1) to examine how the distribution of resources within and outside an Enhanced Language Training Program (ELT) affected a group of newcomers’ access to Internet literacy development; and (2) to discuss ensuing pedagogical and curricular implications for the ELT Program. The relationship between the distribution of resources and a group of newcomers’ access to Internet literacy development was studied through a hybrid of two frameworks: van Dijk’s (2005) digital divide and Warschauer’s (2004) social inclusion. The key findings were that the distribution of resources affected access four ways: (1) resources affected multiple types of access, (2) the effect of resource distribution on access was both cumulative and successive, (3) distribution of resources could either facilitate or impede access, and (4) Internet literacy development could potentially increase or decrease the resources. The findings resulted in implications for the ELT program and teaching.

Large-scale and high-quality multi-view stereo

Vu, Hoang Hiep 05 December 2011 (has links) (PDF)
Acquisition of 3D model of real objects and scenes is indispensable and useful in many practical applications, such as digital archives, game and entertainment industries, engineering, advertisement. There are 2 main methods for 3D acquisition : laser-based reconstruction (active method) and image-based reconstruction from multiple images of the scene in different points of view (passive method). While laser-based reconstruction achieves high accuracy, it is complex, expensive and difficult to set up for large-scale outdoor reconstruction. Image-based, or multi-view stereo methods are more versatile, easier, faster and cheaper. By the time we begin this thesis, most multi-view methods could handle only low resolution images under controlled environment. This thesis targets multi-view stereo both both in large scale and high accuracy issues. We significantly improve some previous methods and combine them into a remarkably effective multi-view pipeline with GPU acceleration. From high-resolution images, we produce highly complete and accurate meshes that achieve best scores in many international recognized benchmarks. Aiming even larger scale, on one hand, we develop Divide and Conquer approaches in order to reconstruct many small parts of a big scene. On the other hand, to combine separate partial results, we create a new merging method, which can merge automatically and quickly hundreds of meshes. With all these components, we are successful to reconstruct highly accurate water-tight meshes for cities and historical monuments from large collections of high-resolution images (around 1600 images of 5 M Pixel images)
