ABSTRACT
The creation of digital ventures in developing countries is an alternative to the generation of jobs in the ICT sector, but the lack of qualified individuals in ICT-related skills inhibits the growth of new companies, a gap that is analyzed with the digital divide theory. This research aims to understand the dynamics using a simulation model that combines aspects of the adoption of ICTS, internet availability, skills, with the entrepreneurial motor of innovation systems. The methodology is developed with data from a national ICT survey and organizations in Colombia. Different scenarios are analyzed regarding ICT education and inclusive policies. Results show that Covid-19 pandemic consequences could have a negative effect during five years and that under a scenario of accelerated growth of ICT, the sector could demand up to 400.000 ICT- related jobs by 2035. The main contribution of this research is the understanding of the ICT systems from an inclusive perspective, identifying the key variables that determine the growth of ventures and the development of digital skills among individuals. © 2023
ABSTRACT
The global COVID-19 crisis has severely affected mass transit in the cities of the global south. Fear of widespread propagation in public spaces and the dramatic decrease in human mobility due to lockdowns have resulted in a significant reduction of public transport options. We analyze the case of TransMilenio in Bogotá, a massive Bus Rapid Transit system that is the main mode of transport for an urban area of roughly 10 million inhabitants. Concerns over social distancing and new health regulations reduced the number of trips to under 20% of its historical values during extended periods of time during the lockdowns. This has sparked a renewed interest in developing innovative data-driven responses to COVID-19 resulting in large corpora of TransMilenio data being made available to the public. In this paper we use a database updated daily with individual passenger card swipe validation microdata including entry time, entry station, and a hash of the card's ID. The opportunity of having daily detailed minute-to-minute ridership information and the challenge of extracting useful insights from the massive amount of raw data (∼1,000,000 daily records) require the development of tailored data analysis approaches. Our objective is to use the natural representation of urban mobility offered by networks to make pairwise quantitative similarity measurements between daily commuting patterns and then use clustering techniques to reveal behavioral disruptions as well as the most affected geographical areas due to the different pandemic stages. This method proved to be efficient for the analysis of large amount of data and may be used in the future to make temporal analysis of similarly large datasets in urban contexts. © The Author(s) 2023.
