ABSTRACT
This research presents a novel methodology and instructional, curricular design for the Cyber-Physical Systems and Human Factors Engineering course for an Industrial Engineering program in Higher Education. The research proposal offers a Competency-Based Education Model, Challenge-based Learning, and Experiential Learning design to create a curricular adaptation to prepare the future workforce for Industry 4.0, driven by digital technologies and strengthening the structure of Education 4.0 in pandemic times. The curricular design was explored and implemented in a national Industrial Engineering virtual course in five different facilities of a Higher Education Institution. Five professors participated in the exploratory study with 265 students in four country regions. The quantitative analysis provided positive findings regarding knowledge delivery and student competency development, confirming the good practices and standards in the proposed curricular design methodology. The final student evaluation results for the course have been favorable. They emphasized the importance of developing skills and knowledge about the enablers and components of Industry 4.0, such as Cyber-Physical-Systems and machine learning. Moreover, they remarked on the importance of human factors to develop a more sustainable society. The research contributes new ideas and perspectives for professors and instructional designers to shape the future of Higher Education. Furthermore, these new research paradigms for competencies in educational innovation shape the emerging virtual and hybrid educational practices in the COVID-19 pandemic and post-pandemic era.
ABSTRACT
The training process of students in higher education in normality or face-to-face responds to teaching and learning in the normal environments of universities, while in the stage of confinement and post-confinement product of COVID-19 a new dynamic had to be developed by part of teachers and students (virtuality and hybridization). In this sense, teachers had to pay special attention to the integrative didactic treatment of the contents, and with it a new way of saying and doing to respond to scientific-technical, socio-economic and cultural changes, on the scenario of each country, and thus, to develop the professional competences of future graduates of higher education.
ABSTRACT
Recent evidence has shown an association between wildfire smoke and COVID-19 cases and deaths. The San Francisco Bay Area, in California (USA), experienced two major concurrent public health threats in 2020: the COVID-19 pandemic and dense smoke emitted by wildfires. This provides a unprecedented context to unravel the role of acute air pollution exposure on COVID-19 severity. A smoke product provided by the National Oceanic and Atmospheric Association Hazard Mapping System was used to identify counties exposed to heavy smoke in summer and fall of 2020. Daily COVID-19 cases and deaths for the United States were downloaded at the County-level from the CDC COVID Data Tracker. Synthetic control methods were used to estimate the causal effect of the wildfire smoke on daily COVID-19 case fatality ratios (CFRs), adjusting for population mobility. Evidence of an impact of wildfire smoke on COVID-19 CFRs was observed, with precise estimates in Alameda and San Francisco. Up to 58 (95% CI: 29, 87) additional deaths for every 1000 COVID-19 incident daily cases attributable to wildfire smoke was estimated in Alameda in early September. Findings indicated that extreme weather events such as wildfires smoke can drive increased vulnerability to infectious diseases, highlighting the need to further study these colliding crises. Understanding the environmental drivers of COVID-19 mortality can be used to protect vulnerable populations from these potentially concomitant public health threats.
ABSTRACT
Argentina is ranked second globally in terms of technically recoverable shale gas, and fourth in shale oil (EIA 2015). The most prolific shale is the Vaca Muerta formation. The objective of this paper is to present geological and reservoir characterization, drilling and production strategies, as well as historical performance and economics of Vaca Muerta. The word petroleum as used in this paper includes oil, natural gas, and natural gas liquids. This paper describes natural fractures and their impact on hydrocarbon productivity. The successful commercial production from this unconventional resource has been driven by many factors, including regional geology, availability of advanced technology such as horizontal drilling and multi-stage hydraulic fracturing, as well as domestic and regional hydrocarbon demand (Sierra 2016). Vaca Muerta itself is very unique with multiple hydrocarbon windows from east to west, ranging from dry gas to wet gas, to light oil and black oil. The productivity of Vaca Muerta is benchmarked to some of the best US shale plays such as the Eagle Ford and the Marcellus. Vaca Muerta contains 1202 Tcf of risked gas in-place and 270 billion barrels of risked oil in-place. It is estimated that 308 Tcf and 16 billion barrels of these resources are technically recoverable (EIA 2015). To date, the total number of horizontal wells exceeds 600, mostly drilled in the black oil window (Secretaria de Energia de Argentina 2020;Wood Mackenzie 2020b). Dubbed the ‘golden goose’ of Argentina, the last decade has seen rapid exploration and development activities. The Argentina state oil company (YPF) leads the development in this region together with its partners. In 2019, production from Vaca Muerta reached 90,000 bbl/d of oil and 1180 MMcf/d of gas, contributing 21% of Argentina's total production (Secretaria de Energia de Argentina 2020;Wood Mackenzie 2020b). YPF predicted these rates would increase by 150% in 2022 (Rassenfoss 2018). Part of this increase will be contributed by La Amarga Chica block, where YPF and its partner, PETRONAS approved their 30-year master development plan in late 2018 to deliver 54,000 boe/d by 2022 (Zborowski 2019). This production increase has obviously been delayed due to the COVID-19 pandemic. The novelty of this paper is integration of geological and reservoir characterization, drilling and production strategies, as well as historical performance and economics of Vaca Muerta. It is concluded that oil and gas potential in the Vaca Muerta shale is significant and rivals the potential of some of the shales widely developed in the Unites States and Canada. © 2021, Society of Petroleum Engineers.
