On the Geographic Allocation of Open Source Software Activities

Open source software (OSS) is marked by free access to the software and its source code. OSS is developed by a 'community' consisting of thousands of contributors from all over the world. Some research was undertaken in order to analyze how global the OSS community actually is, i.e. analyze the geographic origin of OSS developers. But as members of the OSS community differ in their activity levels, information about the allocation of activities are of importance. Our paper contributes to this as we analyze not only the geographic origin of (active) developers but also the geographic allocation of OSS activities. The paper is based on data from the SourceForge research Data Archive, referring to 2006. We exploit information about the developers' IP address, email address and indicated time-zone. This enables us to properly assign 1.3 million OSS developers from SourceForge to their countries, that are 94% of all registered ones in 2006. In addition we have information about the number of posted messages which is a good proxy for activity of each developer. Thus we can provide a detailed picture of the world-wide allocation of open source activities. Such country data about the supply-side of OSS is a valuable stock for both, cross-country studies on OSS, as well as country-specific research and policy advice.Open Source Software, Geographical Location, Open Source Activities

Análise das enquetes internacionais respeito de inovações em FLOSS (software livre e de código aberto)

Given the substantial growth that software and IT sector has had in the last decade, it becomes relevant to measure the impact that this expansion has had on the development of emerging economies. Specifically, the study of the FLOSS production activity is relevant given its contribution to the Knowledge Intensive Services Sector. The aim of this study is to design an innovation survey for the software sector that considers the FLOSS activity separately. Moreover, the paper describes an extensive systematization, evaluation and analysis of diverse technological surveys carried out on the software activity and the FLOSS surveys available specified at a firm level, as a way to collect all the possible background which allows proposing a questionnaire that measures the particularities of FLOSS.A partir del crecimiento sustancial del sector de software y tecnologías de la información en la última década, resulta interesante medir el impacto de esta expansión sobre el desarrollo de las economías emergentes.

A supply side story for a threshold model: Endogenous growth of the free and open source community

The study of social institutions producing and disseminating knowledge has mainly concentrated on two main concepts: Science and Technology. This paper examines a recent institutional form that seems not to resemble either of the other two; that is, knowledge-intensive communities, where individuals freely exchange knowledge through information and communication technology. Using free and open source software as an example, we develop a model where this phenomenon is confronted with Technology with respect to its ability to attract researchers.

Visualizing Spatio-Temporal data

The amount of spatio-temporal data produced everyday has sky rocketed in the recent years due to the commercial GPS systems and smart devices. Together with this, the need for tools and techniques to analyze this kind of data have also increased. A major task of spatio-temporal data analysis is to discover relationships and patterns among spatially and temporally scattered events. However, most of the existing visualization techniques implement a top-down approach i.e, they require prior knowledge of existing patterns. In this dissertation, I present my novel visualization technique called Storygraph which supports bottom-up discovery of patterns. Since Storygraph presents and integrated view, analysis of events can be done with losing either of time or spatial contexts. In addition, Storygraph can handle spatio-temporal uncertainty making it ideal for data being extracted from text. In the subsequent chapters, I demonstrate the versatility and the effectiveness of the Storygraph along with case studies from my published works. Finally, I also talk about edge bundling in Storygraph to enhance the aesthetics and improve the readability of Storygraph

Community-Based Production of Open Source Software: What Do We Know About the Developers Who Participate?

This paper seeks to close an empirical gap regarding the motivations, personal attributes and behavioral patterns among free/libre and open source (FLOSS) developers, especially those involved in community-based production, and its findings on the existing literature and the future directions for research. Respondents to an extensive web-survey’s (FLOSS-US 2003) questions about their reasons for work on FLOSS are classified according to their distinct “motivational profiles” by hierarchical cluster analysis. Over half of them also are matched to projects of known membership sizes, revealing that although some members from each of the clusters are present in the small, medium and large ranges of the distribution of project sizes, the mixing fractions for the large and the very small project ranges are statistically different. Among developers who changed projects, there is a discernable flow from the bottom toward the very small towards to large projects, some of which is motivated by individuals seeking to improve their programming skills. It is found that the profile of early motivation, along with other individual attributes, significantly affects individual developers’ selections of projects from different regions of the size range.Open source software, FLOSS project, community-based peer production, population heterogeneity, micro-motives, motivational profiles, web-cast surveys, hierarchical cluster analysis

Free and open source GIS in South America: political inroads and local advocacy

Geographical information systems (GIS) practitioners worldwide enjoy a growing array of free and open source software (FOSS) options. This software has expanded the accessibility of GIS in economically developing countries while fostering local technical expertise. This article reviews FOSS GIS uptake and advocacy in South America, especially how it relates to a climate of political friendliness toward FOSS in the region. The use or absence of FOSS GIS is assessed in public-facing web maps in South America, first at the national government level, and then at the provincial level using Argentina as a country of study. Local technical support groups and software development initiatives surrounding FOSS GIS in South America are then summarized. Finally, three case studies are presented of notable efforts to build FOSS GIS technical communities at the local level: the FOSSGIS Brasil online magazine, the Geoinquietos Argentina professional network, and the FOSS.4GIS.GOV conference in Brazil. A study of the leaders, dynamics, and practices of these groups can inform others in similar circumstances around the world who are trying to promote FOSS GIS adoption, development, skills, and services

Building Adaptive Capacity: An Analysis of Innovations in Information and Communication Technology in Post-Earthquake Haiti

New information and communication technology (ICT) platforms that emerged in the humanitarian response to the 2010 earthquake in Port-au-Prince, Haiti, have been hyped for their ability to spatialize and coordinate disaster relief efforts and, more broadly, to assist short-term mitigation efforts. This research examines the role of recent innovations in ICT in augmenting the adaptive capacity of the Haitian state to carry out mitigation and adaptation planning. Case studies, analysis of communication flows, and interviews were used to assess the state uptake of three different mobile and open source platforms, including: Ushahidi/Noula, SIS-KLOR, and OpenStreetMap. Findings suggest while these new platforms do offer the potential to increase state efficiencies, assess community need, and produce geospatial information, a combination of fear of responsibility, limited resources, lack of local ownership, and path dependency render foreign technologies unsuitable for Haitian use and impede institutionalization. Recommendations focus on shifting practice from investing in foreign technologies to promoting domestic innovation in ICT by strengthening and updating intellectual property legislation and investing in domestic tech firms. This research is relevant to strategic planners, policy-makers, and international organizations working in the IT secto
