The Conference Reimagined. Postcards, Letters, and Camping Together in Undressed Places
2019
In this paper, five authors account for the rethinking of a conference as a series of postcards, letters, rules and silent moments so that traditional hierarchies of knowledge could be overturned or, at least, sidelined. We recount how the place we convened was enlisted as an actor and the dramas and devices we applied to encounter it. We use this accounting to problematize the conventional practices of goal-oriented meetings and co-authored papers as forms of academic meaning-making. In finding a meeting point where expertise was disorientated and status undressed, we were able to investigate the idea of co-being between human and nonhuman realities as the step social theory needs to take …
Task-Specific Organic Salts and Ionic Liquids Binary Mixtures: A Combination to Obtain 5-Hydroxymethylfurfural From Carbohydrates
2019
The increase in energy demand and depletion of fossil fuels are among major issues of modern society. Valorization and transformation of raw materials in products of industrial value represents a challenge. This justifies the growing interest of scientific research towards the identification of suitable media and methodologies able to pursue above goals, paying attention to matter of sustainability. On this subject, we studied sulfonic-acid functionalized diimidazolium salts as catalysts for the conversion of fructose and sucrose to 5-hydroxymethylfurfural (5-HMF) in an ionic liquid mixture. In general, using these salts allowed us to obtain 5-HMF in good yields from both substrates in mild…
Reducing Relationship Conflict in Virtual Teams With Diversity Faultlines: The Effect of an Online Affect Management Intervention on the Rate of Grow…
2020
The aim of this study was to analyze the effect of an online affect management intervention on relationship conflict through the rate of growth of team resilience in virtual teams with diversity faultlines. Fifty-two 4-person teams participated in a randomized controlled trial design with repeated measures (i.e., three measurement occasions). Teams were randomly assigned to either an intervention designed to help them manage emotions in virtual teams or a control condition. Our findings showed that affect management can reduce the level of relationship conflict in virtual teams with diversity faultlines and that this effect can be explained by the pattern of change in team resilience in re…
Teachers’ Work-Related Well-Being in Times of COVID-19: The Effects of Technostress and Online Teaching
2022
Following the outbreak of the COVID-19 pandemic, one of the first measures implemented in Italy was the transition from frontal teaching to online teaching. The sudden need to use technologies to perform their job has added a source of stress to teachers’ work: so-called technostress. The difficulties experienced in this transition may also have affected the perception of work-related well-being, although other variables, such as the perception of the meaningfulness of work, could alleviate this sense of uneasiness. The study aims to examine the relationships between technostress, online teaching, pleasure in working, and meaningful work perceptions among 219 teachers from different school …
El lenguaje de las tecnologías en la formación de maestros
2020
Este artículo se encuentra disponible a texto completo en la siguiente URL: https://revistas.uam.es/tendenciaspedagogicas/article/view/tp2020_36_09 Este número monográfico de la revista Tendencias Pedagógicas lleva por título "La alfabetización académica". Este trabajo pretende reflexionar sobre las implicaciones educativas que hoy día tiene la competencia mediática en los procesos de enseñanza-aprendizaje. La evolución de las TIC y, sobre todo, de la tecnología móvil, ha provocado una revolución comunicativa educativa y social que afecta al mundo educativo; los contextos edu-cativos son cambiantes y evolucionan rápido, teniendo que adaptarse a los cambios socioculturales, tecnológi-cos, et…
Innoeduca : international journal of technology and educational innovation
2019
La influencia de la tecnología es una realidad innegable en todos los ámbitos de nuestra vida, por ello es fundamental el desarrollo de la Competencia Digital en la formación de postgrado de los futuros profesionales de la educación. Mucho se ha escrito en los últimos años sobre la formación docente en el uso de las tecnologías, y del análisis de los resultados obtenidos en investigaciones previas se constatan limitaciones en la formación específica en TIC recibida en los grados de educación en general, así como la tendencia al desarrollo de esta competencia desde una perspectiva transversal. Bajo esas premisas, en estas líneas se pretende describir y analizar una experiencia de aula basada…
Active degassing of crustal CO2 in areas of tectonic collision: A case study from the Pollino and Calabria sectors (Southern Italy)
2022
Carbon dioxide (CO2) is released from the Earth’s interior into the atmosphere through both volcanic and non-volcanic sources in a variety of tectonic settings. A quantitative understanding of CO2 outgassing fluxes in different geological settings is thus critical for decoding the link between the global carbon budget and different natural processes (e.g., volcanic eruption and earthquake nucleation) and the effects on the climate evolution over geological time. It has recently been proposed that CO2 degassing from non-volcanic areas is a major component of the natural CO2 emission budget, but available data are still sparse and incomplete. Here, we report the results of a geochemical surve…
Not just daycare: nordic mothers in research, development and innovation navigating work and childcare
2022
Nordic welfare policies mitigate work–childcare reconciliation; however, they are not enough for mothers working in intensive work cultures. In addition, there are differences among the three Nordic states in both work–family policies and cultural norms as to how they should be used. In this article, we study the resources mothers who work in research, development and innovation (R&D&I) in Finland, Norway and Sweden rely on in their work–childcare reconciliation. Thematic analysis of interviews with 74 professionals resulted in identifying four main resources: father involvement, parental leave system and daycare, flexible working, and grandparent help and networks. Our analysis brings to v…
High-Performance Lead-Acid Batteries Enabled by Pb and PbO2 Nanostructured Electrodes: Effect of Operating Temperature
2021
Lead-acid batteries are now widely used for energy storage, as result of an established and reliable technology. In the last decade, several studies have been carried out to improve the performance of this type of batteries, with the main objective to replace the conventional plates with innovative electrodes with improved stability, increased capacity and a larger active surface. Such studies ultimately aim to improve the kinetics of electrochemical conversion reactions at the electrode-solution interface and to guarantee a good electrical continuity during the repeated charge/discharge cycles. To achieve these objectives, our contribution focuses on the employment of nanostructured electr…
Temporal perspective on the gender-related differences in online learning behaviour
2022
Although several studies suggested considering gender in online learning, the literature about how male and female students would behave is fragmented. Little attention has been paid to the effect of gender on online learning behavioural patterns. This study aimed at investigating the roles of gender in online learning behaviours by analyzing the gender-related differences of students’ online learning behavioural patterns. We used the case study approach with descriptive statistical analysis, lag sequential analysis, and temporal log data analysis to investigate gender-related differences in students’ online learning behaviours. The results indicated no significant difference in the counts …
