Evaluation of electric scooters as an alternative transportation mode for home-work trips in France
Authors: Bennouna Yacine , Omeiri Dylan , Marquez Timo , Loumeto Ndounzi Jocelyn , Ramond C.
Published: January 2022

In France, the transportation sector is responsible for a third of greenhouse gas emissions. Moreover, in 2020, 72.8% of nationwide home-work trips were made by car. This presents a challenge on how to reduce the associated emissions and an opportunity to promote cleaner modes of transport, for example e-mobility options such as electric scooters. The assumption being that a modal shift of car-users towards e-scooters should result in improved environmental and societal benefits. The paper follows the methodology and actions taken to evaluate the program: a) selection of users for the experimentation, b) analysis of technical specifications and GPS monitoring of e-scooters, c) continuous user-surveys to understand travel habits, and d) the development of an analysis tool to assess the environmental impact compared to other forms of transportation based on their energy consumption (kWh), CO2, NOx and PM10 emitted. The paper presents the initial results of a pilot project in France, which aims to evaluate the influence of micro-mobility to reduce the environmental footprint of home-work trips, and identify user-behaviour challenges and opportunities in the shift of transportation modes.
Large scale energy storage in Uppsala, Sweden: an analysis of voltage fluctuations and a service stacked portfolio
Authors: Hjalmarsson Johannes , Thomas Karin , Boström Cecilia , Berlin A. , Carlsson Fredrik
Published: January 2022

Extensive electrification has created an increased demand of electric energy and power. Congestion issues are expected to become more common as transmission and distribution grids reach their capacity limits. One of the regions in Sweden that has experienced this already is Uppsala. The distribution system operator, Vattenfall Distribution has initiated an R&D project that connects a 5 MW/20 MWh Li-ion battery energy storage system to temporarily ease the grid congestion. This study covers an analysis of grid voltage fluctuations using a largescale battery in a distribution grid. The power quality is examined at the 10 kV connection point of the storage, where voltage and power flow are presented. Also, an example of how value stacking may be implemented is illustrated by adding a secondary service during the year. The test results indicate no significant distortion of the voltage level at the measurement point during smooth ramping. It can be concluded that smooth ramping of the BESS has very low or no impact on the local power quality, and additional services should be provided during the year to create several revenue streams. Future studies could focus on fast ramping of the BESS and stacking services in an intra-season perspective.

Published: January 2022

This study used survey data to evaluate the current status of electrical energy use of commercial office (CO) and governmental office (GO) buildings in Hanoi and Ho Chi Minh City (HCMC) in Vietnam. Main data used in the analyses including floor area and monthly electricity consumption which were gathered from the questionnaire survey for 57 CO and GO buildings in two cities – conducted by the Vietnam Clean Energy Program in 2015. The basic statistical analysis techniques were used to evaluate the electricity consumption intensity of office buildings and preliminarily analyze key factors affecting the energy consumption of these buildings. The results generally showed that CO buildings consumed significantly more electricity than GO buildings in all months of the year and the variation and trend of mean monthly electricity consumption intensity of the buildings strongly depend on that of ambient air temperature. In addition, the energy use intensities (EUIs) of CO buildings, GO buildings, and both buildings (CO+GO) in HCMC (in a hot climate all year round) were higher than those in Hanoi (in a climate with four distinct seasons). The mean EUIs of these buildings in Hanoi, HCMC, and both cities were 105.9, 116.4, and 109.6 kWh/m2 floor. year. The findings of this study are useful information on the status of energy use and energy efficiency of CO and GO buildings in Hanoi and HCMC, thereby contribute scientific bases to the development of policies and solutions to promote the energy efficiency of CO and GO buildings in the coming years and urgent actions for sustainable energy and climate change mitigation in Vietnam.

Crowdfunding: An Alternative Method to Invest
Authors: Giglio Ferdinando
Published: January 2022

Crowdfunding platforms can be used by individuals both to launch fundraising campaigns and to invest their savings.

Crowdfunding is a funding channel through which personal or professional projects of individuals and small businesses can be directly funded by a multitude of entities. The meeting between supply and demand takes place on online platforms that provide information on individual projects and manage the flows of money.

Crowdfunding is an alternative financing channel to that represented by banks or other financial intermediaries. The actual financing of a project, in fact, does not depend on the evaluation made by a single intermediary based on its own financing strategies but on the ability of the proponents to convince a sufficient number of investors to risk their funds in direct support of the initiative.

Authors: Guitart Pérez-Puelles Lourdes , Menéndez Mendoza Dayamith , Sánchez García Jesús Eladio , Torres Díaz Rosario
Published: January 2022

Most studies examine the effects of videogames on the cognitive abilities of young and adult players in experimental situations or for rehabilitation purposes. The aim of the present study is to evaluate the use of computerized commercial games for training sustained attention in primary school children at a high risk of learning disorders. A continuous performance task was used to assess sustained attention in a pre- and post-intervention classical paradigm. The training was organized in groups according to the children’s age and grade and planned in 30-minute sessions twice weekly for 12 weeks. The Student’s t-test was statistically significant for the mean reaction times, showing lower response times after training. It was demonstrated that more than twelve videogame sessions are needed to decrease the reaction time (mean RT) as significant relationship with sustained attention. Statistically significant results by age and grade were achieved before training, while at the end of the intervention only age had the same significance in the three age groups in relation to the mean RT. The results of the study suggest the need to continue exploring videogames in children at high risk of learning disorders.

Authors: Domingo-Coscollola María , Onsès-Segarra Judit , Sancho-Gil Juana M.
Published: January 2022

This article is based on the research project APREN-DO aimed at exploring how secondary school teachers learn. Using an inclusive research approach and visual and narrative methods, we conducted the study with teachers rather than focusing on teachers. Twenty-eight secondary school teachers in the province of Barcelona (Spain) created their learning cartographies, showing what, how, where, with whom, and with what they learn. They then narrated their cartographies and discussed the notions of learning and educational practice in the 21st century. This paper summarizes the results and conclusions about teachers’ learning environments, specificities and considerations regarding their learning, and their thoughts about educational practices. Finally, we present and discuss teachers’ reflections and proposals for redesigning educational practice taking into account the need to contemplate the different literacies and competences that exist in today’s society, encouraging student participation based on their interests and particularities, providing a space for affections and emotions, and prioritizing the personalization of students’ learning and the skill of learning to learn.
Development of Emotional Competences in Higher Education
Authors: Montalvo-García Adolfo , Martí-Ripoll Margarita , Gallifa Josep
Published: January 2022

Research on emotional competence development (ECD) in university students is scarce and shows mixed results. This research establishes what is possible to expect from an optional self-leadership program (SLP) consisting of eight workshops of three hours each, and with a student-centered and experiential approach. The research method was a mixed DEXPLIS design (n=126), which is quasi-experimental ex-post-facto for the first quantitative phase, with experimental and control groups where the CDE A35 self-informed instrument of Bisquerra and Pérez-Escoda was administered, and with participation in qualitative interviews in the second phase. The results indicate global progress in ECD, more evident in intrapersonal emotional competence (EC), although the SLP has not been effective in interpersonal EC. The students perceive their ECD as being very important. In the European Higher Education Area (EHEA), ECD is part of the acquisition of generic or transversal competences, which contribute to more effective and integral training, as well as to a better preparation for the world of work.

Physical activity of children and adolescents during the COVID-19 pandemic.
Review of research and recommendations for pedagogical practice
Authors: Leksy Karina
Published: January 2022

The article aims to emphasize the importance of physical activity for the health and development of preschool and junior school children and adolescents as well as to present global data in this regard during the coronavirus pandemic. Worldwide data previously indicated a decline in physical activity among adolescents (mainly girls), and the COVID-19 pandemic and prolonged lockdown have further aggravated this crisis. The article cites the latest results of research conducted in various parts of the world, which indicate a drastic decline in the level of physical activity during a pandemic, which may become permanent in the future and become a new habit that is dangerous to health. Therefore, at various levels of government, measures are taken to counteract sedentary behaviour and its far-reaching consequences. The school and the family play a huge role in this context, as they should constantly make efforts and motivate children and adolescents to undertake systematic physical activity.
Changing health behaviours in the shadow of the pandemic
Authors: Łukasik Izabela Maria
Published: January 2022

The time when a person feels insecure about their fate, forced to keep a social distance, wear protective masks, subject to quarantine as a result of contact with a person infected with the COVID-19 virus, is characterized by the need to focus on health. The aim of the study is to see to what extent the current pandemic situation triggers health awareness, causing the need to change health behaviours.
The study involved 26 students who were asked about their health-related behaviours. The statements have been analysed and the information obtained explains the research problem.
Few of the students indicated a change in health behaviour. The majority declared such a need, indicating their intention to make such a change, especially in the circumstances of the epidemiological situation. Particular attention was paid to the need to introduce a proper diet and physical activity, as well as to deal with stress. They pointed out that life skills are helpful in these efforts, especially such as interpersonal communication, decision-making skills, critical thinking, self-management, coping with stress, emotions, time management.
It becomes important to familiarize students with models of changing health behaviours, especially since the declared intention to make changes is not binding. Recognizing the process of change, based on intention, allows for more effective action.

Published: January 2022

The diversity of basal ungulates is significant in the late middle Eocene Pondaung Formation (Myanmar). However, the precise identification or attribution of some fossils is sometimes difficult because of the scarcity and poor preservation of the material. We describe here a new genus and species of a Dichobunidae from Paukkaung Kyitchaung 2 locality, that is morphologically and probably phylo­genetically close to a taxon from the early-middle Eocene of Pakistan, and we discuss the attribution of dental material to Myanmarius chitseini Tsubamoto, Egi, Takai, Htike & Zin-Maung-Maung-Thein, 2013, an inderterminate artiodactyl from Pondaung. This study also confirms that dispersals were possible between the Indian subcontinent and Southeast Asia during the first part of the Eocene.

Published: January 2022

A madeira é um dos os compostos orgânicos mais utilizados como matéria-prima no mundo. Suas características químicas, anatômicas e físicas variam sensivelmente mediante aos fatores ambientais. No Cerrado, os solos são naturalmente pobres e com estações secas prolongadas. O estudo das propriedades  da madeira produzida nesse bioma é relevante para compreensão das adaptações morfológicas no xilema secundário para sobrevivência da planta. Objetivou-se estudar as variações e correlações entre propriedades físicas e biométricas de fibras na madeira de Caryocar brasiliense Cambess. do cerrado de Minas Gerais. Coletou-se amostras de incremento do lenho de três árvores, utilizando-se trado de Pressler na altura de 1,30 m em relação ao solo. Determinou-se a densidade, umidade e dimensões das fibras da madeira no sentido medula-casca. Os parâmetros físicos variaram em função das árvores e da posição radial. As médias de densidade básica e umidade verde foram de 0,56 g/cm³ e 96,28%, respectivamente. A tendência observada nas propriedades físicas repetiu-se para os parâmetros biométricos das fibras. As médias de largura, espessura e comprimento de fibras foram 24,13 μm, 5,16 μm e 2,65 mm, respectivamente. O padrão de variação radial da madeira de pequi-do-cerrado indicou que ao se afastar da medula, a densidade básica e o comprimento das fibras são crescentes. Por outro lado, a umidade verde é decrescente. Para largura e espessura da parede celular das fibras não detectou-se tendências claras. Entre as árvores de C. brasiliense, constatou-se variação e correlação das propriedades físicas e particularidades anatômicas da madeira na mesma tipologia de cerrado.

Published: January 2022

O presente artigo apresenta os resultados do Diagnóstico Participativo realizado com o objetivo de identificar as áreas de uso tradicional e os limites entre duas comunidades ribeirinhas na Floresta Nacional do Tapajós, visando compreender a dinâmica de uso e ocupação, pelas comunidades tradicionais, em uma Unidade de Conservação de uso sustentável na Amazônia brasileira. As áreas de uso tradicional, denominadas de Uso Familiar foram registradas por mapeamento participativo e levantamentos de campo. Os problemas ambientais foram identificados durante as entrevistas. O estudo mostrou que a comunidade do Jaguarari ocupa área de 6.271,01 hectares (ha) e Acaratinga ocupa 3.549,87 ha. Foram mapeadas 16 áreas de uso tradicional em Acaratinga e 22 no Jaguarari, que somam 111,44 e 243,08 ha, respectivamente. As áreas de uso intensivo correspondem a menos de 4% do território das comunidades pesquisadas e, de acordo com os comunitários, atende às necessidades a subsistência das famílias. Os principais usos do território estão relacionados com a agricultura, extrativismo madeireiro e não madeireiro, caça, pesca, turismo e pesquisa científica. Os problemas ambientais apontados pelos comunitários foram a caça e pesca predatórias, as queimadas, o furto de madeira e o desmatamento nas áreas de preservação permanente. Dentre as medidas indicadas para minimizar os problemas estão a fiscalização e campanhas de educação ambiental. O estudo indicou, a partir do olhar dos comunitários, que ocorreu a redução de animais e produtos florestais nos últimos cinco anos (2012-2017) e os fatores que afetaram os animais e produtos florestais foram as queimadas, a caça predatória, o desmatamento e o aumento da população. Recomenda-se ao órgão gestor buscar alternativas para o manejo adequado das áreas de uso familiar e investigar o real impacto desses fatores na biodiversidade local.

Is South Africa ready for the future of human germline genome editing? Comparing South African law and recent proposals for global governance
Authors:   Private Law Department, Faculty of Law, University of the Free State, Bloemfontein, South Africa, Kamwendo T , Shozi B
Published: January 2022

Over the past few years, developments in the science of precise editing of human genomes using CRISPR-Cas9 have led many countries that lack specific laws in this area, such as South Africa (SA), to contemplate legal reform. Thaldar et al. recently published five principles to guide legal reform in SA on heritable genome editing. In a similar vein, concerns about the global impact of human germline genome editing have led to calls for a global regulatory mechanism. This is what the World Health Organization has tried to achieve with the recently published ‘Draft governance framework for human genome editing’. In this article, we compare the policies proposed by the draft framework to the current SA legal position, as well as the five guiding principles. The article concludes that SA law is in need of reform in order to meet the global standards that the draft framework seems to be moving towards.

Adult Education and lifelong learning in Southern European societies
Authors: Carvalho da Silva Vanessa Pinto
Published: January 2022

In a context of generalization of education and centralization of knowledge in today's societies, followed by the "intragerationality" (Enguita, 2007) of change, individuals were required to be actively and continuously involved in new stages of education and learning. The right - and the duty - to a relationship with education has been affirmed - beyond initial education and school - which must take place throughout and wide life. The current "cosmopolitanization" of societies (Beck, 2016), underlines the importance of a transnational analysis, for the understanding of social phenomena. Recognizing the importance of a comparing analysis of adult education in Southern European countries, this article aims for the share of regularities and differences that are found in adult education and training systems and in the relationship that adults in each of these countries have with lifelong education. Because we can only understand the adult’s relation with Lifelong Learning by previously analysing his social structure [adult education and training systems], firstly it will be presented the result of a documental analysis which compares adult education systems in Southern European countries [their history, educational contexts, public policies, promoters and adult learning modalities]. Subsequently, and through secondary analysis of data from the Adult Education Survey (2016), the relationship with lifelong learning in each of these countries, through participation and its main barriers, will be compared.

Developmental trajectories of gene expression may reverse in their direction during ageing, a phenomenon previously linked to cellular identity loss. Our analysis of cerebral cortex, lung, liver, and muscle transcriptomes of 16 mice, covering development and ageing intervals, revealed widespread but tissue-specific ageing-associated expression reversals. Cumulatively, these reversals create a unique phenomenon: mammalian tissue transcriptomes diverge from each other during postnatal development, but during ageing, they tend to converge towards similar expression levels, a process we term Divergence followed by Convergence (DiCo). We found that DiCo was most prevalent among tissue-specific genes and associated with loss of tissue identity, which is confirmed using data from independent mouse and human datasets. Further, using publicly available single-cell transcriptome data, we showed that DiCo could be driven both by alterations in tissue cell-type composition and also by cell-autonomous expression changes within particular cell types.

Medullary thymic epithelial cells (mTECs), which produce and present self-antigens, are essential for the establishment of central tolerance. Since mTEC numbers are limited, their function is complemented by thymic dendritic cells (DCs), which transfer mTEC-produced self-antigens via cooperative antigen transfer (CAT). While CAT is required for effective T cell selection, many aspects remain enigmatic. Given the recently described heterogeneity of mTECs and DCs, it is unclear whether the antigen acquisition from a particular TEC subset is mediated by preferential pairing with a specific subset of DCs. Using several relevant Cre-based mouse models that control for the expression of fluorescent proteins, we have found that, in regards to CAT, each subset of thymic DCs preferentially targets a distinct mTEC subset(s). Importantly, XCR1+-activated DC subset represented the most potent subset in CAT. Interestingly, thymic DCs can also acquire antigens from more than one mTEC, and of these, monocyte-derived dendritic cells (moDCs) were determined to be the most efficient. moDCs also represented the most potent DC subset in the acquisition of antigen from other DCs. These findings suggest a preferential pairing model for the distribution of mTEC-derived antigens among distinct populations of thymic DCs.
Crowding-induced phase separation of nuclear transport receptors in FG nucleoporin assemblies

The rapid (<1 ms) transport of biological material to and from the cell nucleus is regulated by the nuclear pore complex (NPC). At the core of the NPC is a permeability barrier consisting of intrinsically disordered phenylalanine-glycine nucleoporins (FG Nups). Various types of nuclear transport receptors (NTRs) facilitate transport by partitioning in the FG Nup assembly, overcoming the barrier by their affinity to the FG Nups, and comprise a significant fraction of proteins in the NPC barrier. In previous work (Zahn et al., 2016), we revealed a universal physical behaviour in the experimentally observed binding of two well-characterised NTRs, Nuclear Transport Factor 2 (NTF2) and the larger Importin-β (Imp-β), to different planar assemblies of FG Nups, with the binding behaviour defined by negative cooperativity. This was further validated by a minimal physical model that treated the FG Nups as flexible homopolymers and the NTRs as uniformly cohesive spheres. Here, we build upon our original study by first parametrising our model to experimental data, and next predicting the effects of crowding by different types of NTRs. We show how varying the amounts of one type of NTR modulates how the other NTR penetrates the FG Nup assembly. Notably, at similar and physiologically relevant NTR concentrations, our model predicts demixed phases of NTF2 and Imp-β within the FG Nup assembly. The functional implication of NTR phase separation is that NPCs may sustain separate transport pathways that are determined by inter-NTR competition.

In plants, selfish genetic elements, including retrotransposons and DNA viruses, are transcriptionally silenced by RNA-directed DNA methylation. Guiding the process are short interfering RNAs (siRNAs) cut by DICER-LIKE 3 (DCL3) from double-stranded precursors of ~30 bp that are synthesized by NUCLEAR RNA POLYMERASE IV (Pol IV) and RNA-DEPENDENT RNA POLYMERASE 2 (RDR2). We show that Pol IV’s choice of initiating nucleotide, RDR2’s initiation 1–2 nt internal to Pol IV transcript ends and RDR2’s terminal transferase activity collectively yield a code that influences which precursor end is diced and whether 24 or 23 nt siRNAs are produced. By diversifying the size, sequence, and strand specificity of siRNAs derived from a given precursor, alternative patterns of DCL3 dicing allow for maximal siRNA coverage at methylated target loci.

N6-methyladenosine (m6A) is an abundant mRNA modification and affects many biological processes. However, how m6A levels are regulated during physiological or pathological processes such as virus infections, and the in vivo function of m6A in the intestinal immune defense against virus infections are largely unknown. Here, we uncover a novel antiviral function of m6A modification during rotavirus (RV) infection in small bowel intestinal epithelial cells (IECs). We found that rotavirus infection induced global m6A modifications on mRNA transcripts by down-regulating the m6a eraser ALKBH5. Mice lacking the m6A writer enzymes METTL3 in IECs (Mettl3ΔIEC) were resistant to RV infection and showed increased expression of interferons (IFNs) and IFN-stimulated genes (ISGs). Using RNA-sequencing and m6A RNA immuno-precipitation (RIP)-sequencing, we identified IRF7, a master regulator of IFN responses, as one of the primary m6A targets during virus infection. In the absence of METTL3, IECs showed increased Irf7 mRNA stability and enhanced type I and III IFN expression. Deficiency in IRF7 attenuated the elevated expression of IFNs and ISGs and restored susceptibility to RV infection in Mettl3ΔIEC mice. Moreover, the global m6A modification on mRNA transcripts declined with age in mice, with a significant drop from 2 weeks to 3 weeks post birth, which likely has broad implications for the development of intestinal immune system against enteric viruses early in life. Collectively, we demonstrated a novel host m6A-IRF7-IFN antiviral signaling cascade that restricts rotavirus infection in vivo.
Response to comment on 'Unexpected plasticity in the life cycle of Trypanosoma Brucei'

We thank Keith Matthews and Stephen Larcombe for their thoughtful comment, which follows the good tradition of public scientific discourse (Matthews and Larcombe, 2022). While their remarks have prompted us to take another critical look at our data, we think that they neither alter our conclusions nor offer a practical alternative explanation. In essence, we see two possible interpretations of our experiments: either the trypanosome life cycle can accommodate a more flexible role for the slender stage, or the definition of the stumpy stage needs to be radically changed. While the first interpretation – which we favour – would not falsify any published work, the second one – which Matthews and Larcombe are proposing – would contradict the literature. Hence, we favour a model with an unexpected phenotypic plasticity for the slender stage and a certain degree of stochasticity in the trypanosome life cycle.
Differences in pathways contributing to thyroid hormone effects on postnatal cartilage calcification versus secondary ossification center development

The proximal and distal femur epiphyses of mice are both weight-bearing structures derived from chondrocytes but differ in development. Mineralization at the distal epiphysis occurs in an osteoblast-rich secondary ossification center (SOC), while the chondrocytes of the proximal femur head (FH), in particular, are directly mineralized. Thyroid hormone (TH) plays important roles in distal knee SOC formation, but whether TH also affects proximal FH development remains unexplored. Here, we found that TH controls chondrocyte maturation and mineralization at the FH in vivo through studies in thyroid stimulating hormone receptor (Tshr-/-) hypothyroid mice by X-ray, histology, transcriptional profiling, and immunofluorescence staining. Both in vivo and in vitro studies conducted in ATDC5 chondrocyte progenitors concur that TH regulates expression of genes that modulate mineralization (Ibsp, Bglap2, Dmp1, Spp1, and Alpl). Our work also delineates differences in prominent transcription factor regulation of genes involved in the different mechanisms leading to proximal FH cartilage calcification and endochondral ossification at the distal femur. The information on the molecular pathways contributing to postnatal cartilage calcification can provide insights on therapeutic strategies to treat pathological calcification that occurs in soft tissues such as aorta, kidney, and articular cartilage.
