It analyzes social factors that impact ICT appropriation and the behaviors and attitudes that advance digital literacy among marginalized rural populations. The authors conducted factor analysis and logistic regressions to survey data collected. Results confirm the presence of a gender divide in ICT adoption. Women were more likely to perceive that ICT use brings social benefits to the community, and considered that ICTs provide better opportunities for the young.Este estudio sobre inclusion digital entre los pobres en comunidades rurales examina como es que los residentes de comunidades serranas remotas en Brasil perciben el uso de la las tecnologias de la informacion y comunicacion (TICs). Analiza los factores sociales que impactan la apropiacion de TIC, asi como el comportamiento y las actitudes que permiten el avance de la alfabetizacion digital en poblaciones rurales marginalizadas. Los autores realizaron un analisis factorial y regresiones logisticas de la informacion recolectada a traves de encuestas. Los resultados confirman la presencia de una brecha de genero en la adopcion de TIC.

Zubiaga, Brian Mac Namee","doi":"10.15353/joci.v12i3.3282","DOIUrl":"https://doi.org/10.15353/joci.v12i3.3282","url":null,"abstract":"An ability to understand the outputs of data analysis is a key characteristic of data literacy and the inclusion of data visualisations is ubiquitous in the output of modern data analysis. Several aspects still remain unresolved, however, on the question of choosing data visualisations that lead viewers to an optimal interpretation of data. This is especially true when audiences have differing degrees of data literacy. In this paper we describe two user studies on perception from data visualisations, in which we measured the ability of participants to validate statements about the distributions of data samples visualised using different chart types. In the first user study, we find that histograms are the most suitable chart type for illustrating the distribution of values for a variable. We contrast our findings with previous research in the field, and posit three main issues identified from the study. Most notably, however, we show that viewers struggle to identify scenarios in which a chart simply does not contain enough information to validate a statement about the data that it represents. In the follow-up study, we ask viewers questions about quantification of frequencies, and identification of most frequent values from different types of histograms and density traces showing one or two distributions of values. This study reveals that viewers do better with histograms when they need to quantify the values displayed in a chart. Among the different types of histograms, interspersing the bars of two distributions in a histogram leads to the most accurate perception. Even though interspersing bars makes them thinner, the advantage of having both distributions clearly visible pays off. The findings of these user studies provide insight to assist designers in creating optimal charts that enable comparison of distributions, and emphasise the importance of using an understanding of the limits of viewers’ data literacy to design charts effectively.","PeriodicalId":280460,"journal":{"name":"J.

To continue and enrich the conversation, this study first examines the contrasting stances revealed in the CI listserv discussion and derives the CI researchers’ major concerns about the platform. Under the light of these concerns, we then explore the nature of Facebook’s Free Basics in relation to community development through analysis of one of the forefront services that Free Basics offers, i.e., Facebook. Specifically, we examine relationships between uses of Facebook and information technology (IT) identity formation and social capital. We argue that although projects operated by private companies may possess potential for supporting community development, much consideration is needed in embracing the technology solutions due to the risks and restrictions they can impose on its users. We also suggest the CI researchers to open the next round of discussion regarding ways to thoroughly assess possible flaws of Free Basics and help users of the platform make more informed decisions. IT identity is a new theory that can help shed new light on the challenges of using platforms such as Free Basics and their contribution to community development.","PeriodicalId":280460,"journal":{"name":"J.

Government-led open data initiatives have spread across the globe, and civil society or technologist experiments using data to improve governance have been spreading organically, from budget monitoring in Nigeria, to court transparency projects in Argentina. It is increasingly seen as enabler of a “data revolution” in the process of decision-making and accountability. However, understanding how experience of open data will vary from country to country and context to context, and, understanding the common features of open data that are shaping its implementation in these diverse settings, requires broad-based research framework. It requires research that can engage with both existing realities of decision-making in sectors, acknowledging the growing complexity of this process in an increasingly networked society. In this paper we have reviewed the framework of the “Open Data in Developing Countries”(ODDC) project, the largest research project on the impact of open data in developing countries to date. The framework was designed to help explore the link between openness in the data ecosystem, decentralized changes in decision-making, and positive and negative emerging impacts such as transparency and accountability, inclusion and empowerment as well as innovation and economic development. It was tested to generate cross-learning from 17 in-depth cases studies in 14 countries, as well as generate policy-relevant findings. This paper reviews and updates the original framework based on the findings and reflections developed during the research project.","PeriodicalId":280460,"journal":{"name":"J.
