Livestock raising is an important sector of the Colombian economy, which will face serious challenges in the next decade, including adaptation to and mitigation of climate change. Colombia must change the model of livestock production in a very short time by freeing up areas of pasture for other uses and focusing intensified livestock production in suitable zones. Despite the urgency and the magnitude of the required changes, only isolated small-scale initiatives exist. Colombia therefore has the challenge to scale-up these initiatives 1 , but at present it has no program designed to achieve this objective. We started by analyzing the policies, actors, and existing initiatives in Colombia. We then sought to understand the potential for and the limitations to scaling-up promising initiatives to face the challenges of climate change in the livestock sector. We identified the key elements from previous initiatives and classified them into the conceptual spaces identified in the theory of scaling-up. These are the spaces in matters of: policy, fiscal and financial matters, institutional capacity, learning, partnerships, and technical matters, emphasizing the importance of the technical dimension. Finally, we propose some elements for the design of Colombia's national program of livestock raising.
The goal of the research presented in this paper is to design and incorporate new technologies into railway bogie-mounted sensors. It is often impossible to connect the mounted systems to physical wires due to their location in an inaccessible position or the distance to the energy source. Therefore, another power source must be used to solve this problem. Energy harvesting technology is an increasingly popular solution that extracts energy from the ambient environment and transforms it into electrical energy. Using piezoelectric transducers, it is possible to transform the vibrations experienced by the bogie into energy that can be used to power the sensors. A prototype with multiple piezoelectric transducers has been designed, built and subjected to tests to validate the technology. The experimental results for all of the different configurations tested and levels of energy collected are presented.
Purpose
This paper aims to propose the development of formal (scientific content) and informal (content for science communication) educational activities in an inclusive and safe way, involving two essential elements, virtual reality (VR) and the digital library; as well as the implications for its enforcement such as educational strategies in the university setting and for the encouragement of scientific culture in society.
Design/methodology/approach
For the integration of content, a simplified conceptual model was designed first, in which universities and research centers are seen as complex systems where different subsystems, from which processes and information resources are derived, converge. To cover the model’s elements, a descriptive documentary review was developed, looking to synthesize each element’s contexts and implications.
Findings
The need to establish transdisciplinary relationships between the VR and the digital library is determined with the goal to integrate educational activities using technology, with the purpose of studying contents from the scientific point of view, as well as with the possibility of transforming them into contexts of general access for society, with the objective of social appropriation of knowledge, citizen science and social innovation. In the conclusion section, some implications in the implementation of this type of initiatives are presented.
Originality/value
The aspects that set this paper apart are: treating VR as emerging documents tending to measure their direct impact, not as isolated elements of a collection; identifying the digital library’s social influence actions through VR; and generating processes to encourage the creation of contents with a differentiated focus according to the population served.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
