Title A name given to the resource Covid-19’s Impact on European Power Sectors: An Econometric Analysis Creator An entity primarily responsible for making the resource David Schönheit, Dominik Möst, Philipp Hauser, Hendrik Scharf, Carl-Philipp Anke Description An account of the resource Covid-19 affects the personal lives of millions and led to an economic crisis. Changed behavioral patterns and a reduction of industrial activity result in a reduction in power demand, and thus Covid-19 impacts the power systems around the world. Bottom-up mapping of the effect of Covid-19 on the energy demand is challenging, if not impossible. In order to analyze the impact of the pandemic on power demand, we instead propose a simplified approach based on an econometric analysis that quantifies the country-wide load reduction of Covid-19, using the number of active cases as well as the specific lockdown period as proxies. The time span covered is from 1 January 2016 to 31 August 2020. This long time span allows us to investigate the effect of Covid-19 on the power demand. We find that in Germany (DE) and Great Britain (GB) the power demand is reduced by about 1–1.7 MW per case, while in France the demand increased by 1 MW per case during times outside of the lockdown. On the other hand, in France the lockdown itself has a much higher load reduction effect in France than in GB and DE. Based on the elasticity of power demand regarding Covid-19 cases, we calculate the impact of Covid-19 on the power prices through reduced loads. We find that Covid-19 reduced power prices by 3 to 6 EUR per MWh. The effect of Covid-19 on carbon emissions in the power sector is likely to be small. In Germany, the country with the highest absolute level, emissions in the power sector were reduced by approximately 2% (4 Mio. t CO2).

Title A name given to the resource Educación superior en México, COVID-19 y la respuesta emergente: el caso de la Universidad Autónoma Metropolitana Xochimilco Creator An entity primarily responsible for making the resource David Sebastián Contreras Islas, Diana Minerva Espejel Alejandro, Roberto Flores Rojas Description An account of the resource Adaptar todas las actividades que una de las universidades más grandes de México realiza de forma presencial a un formato virtual no es sencillo, ya que requiere del conocimiento de todo el proceso organizativo y un sustento en su legislación. Este artículo analiza la respuesta de la Universidad Autónoma Metropolitana (UAM) Unidad Xochimilco, donde el Programa Emergente de Educación Remota (PEER), entre otras medidas, se usó para solventar las labores durante el brote de COVID-19. A partir de la historia de vida de una alumna de posgrado reconstruimos la puesta en marcha del PEER y aplicamos tres ejes de análisis: la implementación de programas, la comunicación organizacional y la vulnerabilidad asociada a la toma de decisiones. Nuestro análisis revela una serie de tensiones entre los contenidos de la legislación universitaria y la forma en que actores de ventanilla, como alumnos y trabajadores, vivieron el proceso de migración de las actividades sustantivas a un formato en línea. Nuestros resultados sugieren que ciertas carencias en la comunicación organizacional están afectando la capacidad de la UAM para responder de forma eficiente ante situaciones emergentes manteniendo al mismo tiempo los principios de participación y desconcentración funcional planteados en su Ley Orgánica. Asimismo, indican la relevancia de generar protocolos que coadyuven a garantizar la correcta protección de grupos vulnerables de la comunidad universitaria, como parte de los procesos de toma de decisiones. Finalmente, se presentan posibles líneas de investigación futuras para el mejor entendimiento de esta problemática.

Title A name given to the resource Data use by small scale horticultural producers in Wales, U.K.: directions for the provision of digital information in rural management Creator An entity primarily responsible for making the resource David Skydmore Description An account of the resource Food security for small-scale farmers requires resilient farming practice. Farms are affected by economic, market, regulatory and social factors and the farmer needs to be provided with relevant, reliable and up-to-date information on these factors. A case study is given of horticulture in Wales where land holdings tend to be small, being of less than 2ha. It showed the growers have an age profile predominating in the older ranges, such that inter-generational skills are likely to be lost. Trade is mainly through on-farm sales, local tourism outlets or local retailers. The majority of growers have access to digital technologies. The most useful to the small-scale farmer are communication devices and knowledge technologies supplying information including that on market prices, weather, soil conditions and best practice. This information increases its benefits if it provides scenarios and predictive models. To use the information, the farmers need an adequate agricultural education. The knowledge systems need to be developed and maintained and this often requires support from Government and Producer Organizations. Use of the knowledge technologies and the two-way supply of information between the farmers and the Producer Organizations and Government will help improve crop productivity, sustainability, rural economics and household well-being.

Title A name given to the resource Embarking digital learning due to COVID-19: Are teachers ready? Creator An entity primarily responsible for making the resource David Sulistiawan Aditya Description An account of the resource The COVID 19 pandemic insists schools to close and embark on the digital environment to keep learning to happen. Implementing this learning in educational settings faces challenges related to human resources and infrastructure issues particularly in developing countries. This study investigated the teachers’ readiness in conducting digital learning in Yogyakarta, Indonesia. This exploratory study employed an online questionnaire and semi-structured interviews via either voice calls or video calls to safely gather both quantitative and qualitative data from 62 teachers of 27 different schools in the middle of social distancing regulation in Yogyakarta. The study revealed that the majority of teachers were psychologically, technologically, and pedagogically ready to conduct digital learning. However, the digital learning problem was mostly coming from teachers who teach in rural areas. Students’ technology affordances mainly caused a disparity of digital learning success. The findings suggest that the choice of technology adoption and methodology adjustment can be viewed as a solution to the current digital learning problem. Finally, instead of the teachers’ readiness, the students’ readiness and teachers’ technological pedagogical knowledge are other key aspects of the digital learning success. Thus, these two issues are suggestive for further studies.

Title A name given to the resource Pandemic Supply Chain Research: A Structured Literature Review and Bibliometric Network Analysis Creator An entity primarily responsible for making the resource David Swanson, Luis Santamaria Description An account of the resource In early 2020, COVID-19 infected people throughout the world and brought world commerce to a standstill. Many believe that governments and global businesses were not as prepared as they should have been. While academics have occasionally predicted the economic problems that could result from pandemics, until 2020, there had been scant research that addresses supply chain management issues during pandemics. Eighty-four percent of all pandemic supply chain research was published in the first ten months of 2020. Since the world now finds itself operating supply chains in response to the pandemic, this literature needs to be summarized and articulated for understanding and future research. This literature review addresses that need by summarizing the research which has been generated since 1997, focusing primarily on the bulk of the research that has been published since the COVID-19 pandemic began. Research tools are used to summarize the literature citations, and the articles are coded according to some important variables to further delineate their details. This research also includes a bibliometric co-citation analysis, which clusters the pandemic supply chain literature by author, journal, and article. The findings are that pre-COVID-19 research on pandemic supply chains was primarily about influenza and the healthcare supply chain, whereas post-COVID-19 research provides more analysis of the food supply chain and uses a wider variety of research methods, including simulation, modeling, and empirical methods.

Title A name given to the resource Effects of cluster thinning and irrigation amount on water relations, growth, yield and fruit and wine composition of Tempranillo grapes in Extemadura (Spain) Creator An entity primarily responsible for making the resource David Uriarte, María Esperanza Valdés, Daniel Moreno, Esther Gamero, María del Henar Prieto, Raquel Manzano, Joaquín Picón, Diego Sebastiano Intrigliolo Description An account of the resource Aim: The effects of cluster thinning and irrigation regime on vine performance and grape and wine quality of Tempranillo grapevines were studied in a field experiment carried out in Extremadura in Spain. Methods and results: Treatments were combinations of two irrigation doses (25% and 100% of estimated crop evapotranspiration) and two crop levels (thinned and unthinned vines). Cluster thinning was performed just before veraison to retain five clusters per m2 of vine leaf area. Results showed that irrigation amount produced important differences in stem water potential, leaf area index and berry growth but cluster thinning did not significantly affect these parameters. However, cluster thinning independently of the irrigation amount, advanced by seven days grape maturity and largely affected the main grape quality parameters, increasing total soluble solids concentration, pH, total anthocyanins and phenolic content and reduced must yield. Wines made from grapes of the thinned treatments also had higher contents of anthocyanins, tanins and colour index. This increasing effect was more noticeable in the lower irrigation dose. Similarly, the higher irrigation amount reduced phenolic content of wines. Conclusion: Both, lower irrigation rates and cluster thinning, despite decreased yield, improved wine composition. Overall thinning had a larger impact on grape and wine composition than irrigation. Significance and impact of study: In the semi-arid environment of the Extremadura region of Spain, irrigation in Tempranillo is important to obtain economically sound yield. However, the irrigation dose to apply might vary depending on the desired wine style. Irrigation to replace potential evapotranspiration should be avoided for premium wine production and, in these cases; deficit irrigation is probably preferred as a tool to increase yields but minimizing the negative effects on fruit and wine quality. Cluster thinning, performed just before veraison, can be also applied to accelerate ripening improving the overall fruit phenolic composition.

Mardis, Matthew Hickenbotham, Vincent Magrini, James Eldred, J Phillipe Latreille, Richard K Wilson, Don Ganem, Joseph L. DeRisi Description An account of the resource Because of the constant threat posed by emerging infectious diseases and the limitations of existing approaches used to identify new pathogens, there is a great demand for new technological methods for viral discovery. We describe herein a DNA microarray-based platform for novel virus identification and characterization. Central to this approach was a DNA microarray designed to detect a wide range of known viruses as well as novel members of existing viral families; this microarray contained the most highly conserved 70mer sequences from every fully sequenced reference viral genome in GenBank. During an outbreak of severe acute respiratory syndrome (SARS) in March 2003, hybridization to this microarray revealed the presence of a previously uncharacterized coronavirus in a viral isolate cultivated from a SARS patient. To further characterize this new virus, approximately 1 kb of the unknown virus genome was cloned by physically recovering viral sequences hybridized to individual array elements. Sequencing of these fragments confirmed that the virus was indeed a new member of the coronavirus family. This combination of array hybridization followed by direct viral sequence recovery should prove to be a general strategy for the rapid identification and characterization of novel viruses and emerging infectious disease.

Title A name given to the resource Quantifying the roles of vomiting, diarrhea, and residents vs. staff in norovirus transmission in U.S. nursing home outbreaks. Creator An entity primarily responsible for making the resource David Young, Benjamin A. Lopman, Aron J. Hall, Paul A. Gastañaduy, Prabasaj Paul, Carly Adams, Zach Marsh Description An account of the resource The role of individual case characteristics, such as symptoms or demographics, in norovirus transmissibility is poorly understood. Six nursing home norovirus outbreaks occurring in South Carolina, U.S. from 2014 to 2016 were examined. We aimed to quantify the contribution of symptoms and other case characteristics in norovirus transmission using the reproduction number (REi) as an estimate of individual case infectivity and to examine how transmission changes over the course of an outbreak. Individual estimates of REi were calculated using a maximum likelihood procedure to infer the average number of secondary cases generated by each case. The associations between case characteristics and REi were estimated using a weighted multivariate mixed linear model. Outbreaks began with one to three index case(s) with large estimated REi's (range: 1.48 to 8.70) relative to subsequent cases. Of the 209 cases, 155 (75%) vomited, 164 (79%) had diarrhea, and 158 (76%) were nursing home residents (vs. staff). Cases who vomited infected 2.12 (95% CI: 1.68, 2.68) times the number of individuals as non-vomiters, cases with diarrhea infected 1.39 (95% CI: 1.03, 1.87) times the number of individuals as cases without diarrhea, and resident-cases infected 1.53 (95% CI: 1.15, 2.02) times the number of individuals as staff-cases. Index cases tended to be residents (vs. staff) who vomited and infected considerably more secondary cases compared to non-index cases. Results suggest that individuals, particularly residents, who vomit are more infectious and tend to drive norovirus transmission in U.S. nursing home norovirus outbreaks. While diarrhea also plays a role in norovirus transmission, it is to a lesser degree than vomiting in these settings. Results lend support for prevention and control measures that focus on cases who vomit, particularly if those cases are residents.
