The Right to Education and ICT during COVID-19: An International Perspective
2020
There is a lack of concluding evidence among epidemiologists and public health specialists about how school closures reduce the spread of COVID-19. Herein, we attend to the generalization of this action throughout the world, specifically in its quest to reduce mortality and avoid infections. Considering the impact on the right to education from a global perspective, this article discusses how COVID-19 has exacerbated inequalities and pre-existing problems in education systems around the world. Therefore, the institutional responses to guaranteeing remote continuity of the teaching&ndash
Microbial fuel cell with Cu-B cathode and KMnO4 catholyte
2017
The increasing of standard living causes the increases energy consumption and waste or wastewater production. The possibility to combine wastewater treatment and electricity production can accomplish a microbial fuel cell. The possibility of wastewater treatment using the Cu-B catalyst with KMnO4 catholyte for microbial fuel cells is presented in this paper. The measurements covered comparison of changes in the concentration of COD, NH4+ and NO3- in the reactor without aeration, with aeration and with using a microbial fuel cell (with Cu-B cathode and KMnO4 catholyte). The reduction time for COD with the use of microbial fuel cell with the Cu-B catalyst (and KMnO4 catholyte) is similar to t…
Electricity production in microbial fuel cell with Cu-B alloy as catalyst of anode
2015
Considering the increasing standard of living, the energy consumption increases as well, and so does waste production. However, there is a possibility to combine energy production and wastewater treatment. A device that can accomplish this task is a microbial fuel cell. In microbial fuel cells activated sludge bacteria can be used for electricity production during wastewater treatment. One of the problems with microbial fuel cells is a low current density of those energy sources. Nonetheless, it is possible to increase the current density by using the catalyst for fuel electrode (anode) – as long as a low cost catalyst can be found. The possibility of wastewater treatment using the Cu-B all…
Comparison of powering the microbial fuel cell with various kinds of wastewater
2019
The possibility to combine wastewater treatment and electricity production can accomplish a microbial fuel cell. Microbial fuel cells use glucose from wastewater as a fuel. In recent years, both production of municipal and industry wastewater increases very much. Municipal wastewater is directed to the wastewater treatment plant. While industry wastewater can be use as a fertilizer. But, both municipal and industry wastewater can be used in the microbial fuel cells. The comparison of powering the microbial fuel cell with municipal and process wastewater from yeast production is presented in this paper. The measurements covered comparison of changes in the concentration of COD in the reactor…
Understanding Consumers’ Convenience Orientation. An Exploratory Study of Fresh-Cut Fruit in Italy
2021
In Western society, the fresh-cut fruit market is experiencing significant growth, especially in Italy, where, in 2019, the fresh-cut fruit sales volume increased by 35% compared with the previous year. This study aims to understand Italian consumers&rsquo
The Use of Mobile Payment Systems in Post-COVID-19 Economic Recovery : Primary Research on an Emerging Market for Experience Goods
2021
This study investigated whether mobile payment services could drive post-COVID-19 pandemic recovery in the ‘experience goods’ sector (e.g., tourism) utilising Bandura’s self-efficacy or social cognitive theory. It explored the factors influencing the intention to continue using mobile payment services and the intention to recommend these to others. An empirical survey was conducted to assess the study variables, and the data obtained therefrom were analysed using the industry-standard Cross-Industry Standard Process for Data Mining method. The study results suggest that personal innovativeness and perceived trust influence consumers’ intention to continue using mobil…
Modeling the Sustainable Educational Process for Pupils from Vulnerable Groups in Critical Situations: COVID-19 Context in Lithuania, Latvia, and Est…
2022
The critical situation in education caused by COVID-19 has significantly reduced the involvement of pupils from vulnerable groups, particularly those with low learning achievements. The aim of this study is to reveal the modeling of the sustainable educational process and the factors that ensure optimal learning achievements of pupils from vulnerable groups in general education schools in critical educational transformation situations. To reveal the factors ensuring the sustainability of educational processes, this study was conducted in three Baltic countries (Lithuania, Latvia, and Estonia) involving 1432 subject teachers from public education schools. The results of the study highlight t…
Sustainability Development in Mathematics Education : A Case Study of What Kind of Meanings Do Prospective Class Teachers Find for the Mathematical S…
2019
In this article, our focus is on sustainable development in mathematics education from the point of view of teacher training. The aim was to develop prospective teachers’ content knowledge and pedagogical content knowledge of school mathematics. As a case study, we chose the mathematical symbol “a/b”, and examined how prospective class teachers in Finland connect it to the concepts of fraction, ratio, division, rational number or probability. Mathematics textbooks often have a central role in lessons, and they affect strongly how pupils understand concepts and the relationships between them. We chose languaging as a multi-semiotic approach to interpreting what kind of meanings the prospecti…
