In order to evaluate the effectiveness of the gonadotropin-releasing hormone agonist leuprolide acetate in distinguishing gonadotropin deficiency from delayed puberty, a single subcutaneous dose of 20 micrograms/kg of leuprolide acetate was administered at 07.00 h to 14 patients with constitutionally delayed puberty and to 8 gonadotropin-deficient subjects, and serum gonadotropin and testosterone levels were determined at baseline and 1,2,3,6,12, and 24 h thereafter. The increase in gonadotropin and testosterone levels was significant in patients with delayed puberty, so that the mean peak luteinizing hormone and to a lesser degree the mean peak testosterone levels clearly differentiated normally delayed from gonadotropin-deficient puberty. However, when the peak gonadotropin and testosterone concentrations were analyzed individually, there was a considerable overlap between the two groups of males, limiting the usefulness of this test.
Smart ITS Sensor for the Transportation Planning Based on IoT Approaches Using Serverless and Microservices Architecture
(Institute of Electrical and Electronics Engineers, 2018) Luis Felipe Herrera-Quintero; Julian Vega-Alfonso; Klaus Banse; Eduardo Carrillo
Currently, there are many challenges in the transportation scope that researchers are attempting to resolve, and one of them is transportation planning. The main contribution of this paper is the design and implementation of an ITS (Intelligent Transportation Systems) smart sensor prototype that incorporates and combines the Internet of Things (IoT) approaches using the Serverless and Microservice Architecture, to help the transportation planning for Bus Rapid Transit (BRT) systems. The ITS smart sensor prototype can detect several Bluetooth signals of several devices (e.g., from mobile phones) that people use while travelling by the BRT system (e.g., in Bogota city). From that information, the ITS smart-sensor prototype can create an O/D (origin/destiny) matrix for several BRT routes, and this information can be used by the Administrator Authorities (AA) to produce a suitable transportation planning for the BRT systems. In addition, this information can be used by the center of traffic management and the AA from ITS cloud services using the Serverless and Microservice architecture.
The Performance Gap of Policy Information Systems: A Knowledge Infrastructure Assessment Framework
(2023) Eduardo Carrillo; Catalina Frigerio; María Jesús Valenzuela; Alessia Aquaro; Jean‐Christophe Mauduit; Ine Steenmans; Maria-Paz Sandoval
Digital technologies’ development and their ubiquity has significantly changed the way information is collected and shared. These changes are also observed in the ways that knowledge and information used to design and implement Science, Technology, and Innovation (STI) policies are increasingly made accessible via digital platforms. Lacking, however, are evaluation frameworks to measure the performance and effectiveness of public information systems used for STI policy work. This limits what we know about what aspects work for whom, when, and why. As a response to this gap limiting our collective capacity for improving their utility, this paper presents an assessment framework tool for STI policy-focused digital knowledge platforms. Our proposition is informed by theoretical lessons from the areas of work on Knowledge Infrastructures (KIs) and Next Generation Repositories (NGRs), and practical experiences from policy professionals working in STI policy domains. The tool’s architecture is structured around three interdependent thematic pillars of performance in the production, aggregation, distribution, and maintenance of knowledge in digital information platforms: the communities pillar, the technical systems pillar, and the sustainability pillar. To test the design and utility of our proposed evaluation framework, we applied it on a digital platform of STI policy instruments maintained by the United Nations Educational, Scientific, and Cultural Organization (UNESCO), the Global Observatory for Science, Technology, and Innovation Policy (GO-SPIN) platform. We conclude with reflections on future areas for evaluation framework development.
