Authors: Suárez Guerrero Cristóbal , Ros Garrido Alicia , Lizandra Jorge 
Published: October 2021

El mundo requiere personas con conocimientos, habilidades y actitudes que permitan un desarrollo completo de la ciudadanía en un ecosistema digital. Una respuesta educativa a esta exigencia social es la competencia digital. Así, esta finalidad exige niveles óptimos de desarrollo de la Competencia Digital Docente (CDD), en especial en el sector de la Formación Profesional (FP). Con la idea de atender este contexto educativo, en este trabajo se propone un marco de comprensión que integra de forma unitaria la visión sobre la pedagogía, los recursos y la evaluación para entender, evaluar y proponer mejoras en la competencia digital del profesorado de FP. Empleando un enfoque cualitativo, se realizaron once entrevistas en profundidad sobre la CDD del profesorado de FP de la provincia de Valencia (España). Estos datos fueron analizados desde la caracterización de 4 escenarios educativos con tecnología (aprendizaje individual, la enseñanza con TIC, aprendizaje colaborativo y autoaprendizaje del alumnado). La principal conclusión detectada es que los docentes entrevistados tienen conocimientos de algunos recursos y aplicaciones tecnológicas, actitud y capacidad para incorporarlos a su práctica docente. En cambio, no integran la tecnología en la evaluación de los aprendizajes al mismo nivel competencial que en las otras dimensiones.
World requires people with knowledge, skills and attitudes that allow a full development of citizenship in a digital ecosystem. An educational response to this social demand is digital competence. Thus, this purpose requires optimal levels of Digital Teaching Competence (DTC), especially in the Vocational Education Training (VET) sector. With the aim of ​​attending to this educational context, this work proposes a understanding framework that integrates the vision of pedagogy, resources and evaluation to understand, evaluate and propose improvements in the digital competence of VET teachers. Using a qualitative approach, eleven in-depth interviews were conducted on the DTC of VET teachers in the province of Valencia (Spain). These data were analysed from the categorization of 4 educational scenarios with technology (individual learning, teaching with ICT, collaborative learning and student self-learning). The main conclusion detected is that interviewed teachers have knowledge of some technological resources and applications, attitude and ability to incorporate them into their teaching practice. However, they do not integrate technology in the learning assessment at the same competence level as in the other dimensions.

How do you recover after a crisis?
This session will reflect on the work done by and with the sco.wiki community to recover and rebuild after the negative international press attention that surrounded the wiki in 2020. I’ll talk about on- and off- wiki community development, partnership development, the challenges that still face the project, and hopes for the future. I’ll also reflect on care in volunteer management, and why we should always remember that there are real people behind keyboards.
As Scotland Programme Coordinator for Wikimedia UK, I’ve been involved in supporting the community post-crisis, and have been impressed and heartened by the volume of work which has taken place since sco.wiki hit the headlines. I’d like to take this opportunity to tell the story of a group of editors and Scots speakers who are determined that the wiki should survive, grow, and thrive.
Abstract id. 11:
In the lead-up to the launch of Abstract Wikipedia, a sufficient body of linguistic information, based on which the text within for a given language can be generated, must be in place so that different sets of functions, some working with concepts and others turning these into word sequences, can work together to produce something natural in that language. To achieve that information body's development requires more thorough consideration of a number of linguistic aspects sooner rather than later.
This session will thus discuss aspects of language planning with respect to Wikidata lexicographical data and natural language generation, including the compositionality and manipulability of lexical units, the breadth and interconnectedness of units of meaning, and the treatment of variation among a language’s lects broadly construed. Special reference to the handling of each of these aspects for Bengali and those linguistic varieties often grouped with it will be presented.
Help your communities grow!
Authors: Evellin Benoît 
Published: October 2021

We all have been newcomers one day, and gradually we managed to find our way to become experienced users. But how many promising newcomers have abandoned this same journey because they didn't understand our tools or our policies, or lacked human-to-human support?
The Wikimedia Foundation Growth team is working on a set of tools that help communities to welcome newcomers and grow wikis in size and quality. These features have been shown to increase the activation, retention, and edit volume of newcomers.

Newcomer homepage: a special page that hosts the "Newcomer tasks" and is a good place for a newcomer to get started. The homepage gives access to many resources, including a link to a volunteer mentor who would reply to their questions.
Newcomer tasks: a feed of suggested edits that help newcomers learn how to make simple edits on their preferred subjects. Newcomers have been making productive edits through this feed! The feed is located on the homepage, as the starring feature.
Help panel: a platform to provide resources to newcomers while they are editing. When newcomers work on "Newcomer tasks", the help panel guides them on what to do.

All of these features are available right now, on both desktop and mobile: communities can request their deployment if they want to try them.
This presentation will be about discovering the Growth tools, know their benefits, and see how to implement them in order to increase chances to grow your community in a qualitative way. We will also show the future of these features.
Benefits of Exercise in Heart Failure: A Systematic Review and Meta-Analysis of Randomized Clinical Trials

Published: October 2021

Objective: To update Sagar et.al. systematic review and meta-analysis on exercise-based rehabilitation for heart failure.
Methods: A systematic review and meta-analysis of randomized clinical trials on exercised-based cardiac rehabilitation. MEDLINE, OVID and cross references were searched for RCTs published between February 2013 up to August 2018. Trials with at least 6 months follow up were included if exercise training program alone or as a component of comprehensive cardiac rehabilitation was compared with groups without exercise prescription.
Results: A total of 11,989 patients were included in the 43 randomized clinical trials predominantly with reduced EF and NYHA class ll -lll. Exercise training program prescription in heart failure patients reduced the all-cause mortality (RR=0.76; 95%CI= 0.66, 0.87; P= 0.001), all cause hospitalization after 12 months (RR=0.70; 95% CI= 0.52, 0.96; P= 0.02) rehospitalization due to heart failure (RR= 0.49; 95% CI= 0.44, 0.55; P= <0.0001) and improvement in quality-of-life scores (RR= -0.36; 95% CI= -0.58, -0.14; P= 0.002). Among these health quality related outcomes, the all-cause mortality and the hospitalization admission after 12 months follow up showed a significant association with exercise therapy program, particularly on exercise setting(p=0.026) and exercise dose (p=0.013), respectively, as revealed by the univariate meta-regression results.
Conclusion: This study has shown that exercise therapy either in center or home based has benefited heart failure patients in reducing the risk of all-cause mortality up to 12 months, hospital admission up 12 months, and has given a better quality of life. The new studies included have further strengthened the findings of previous studies that an exercise therapy program provides benefit to heart failure patients, either as an “alone” intervention or together with a cardiac rehabilitation program; and that the setting and dose of an exercise therapy program provide significant contribution to a reduced risk in all-cause mortality and hospitalization after 12 months follow up, respectively.
Comparison of Single Antibiotic Paste Nitrofurantoin and Calcium Hydroxide Paste as Intracanal Medicaments in Alleviating Post-Operative Pain in Patients with Symptomatic Irreversible Pulpitis -A Randomized Controlled Trial
Authors: Abbasi Hira , Lal Abhishek , Shamim Jaffrani Ammara 
Published: October 2021

Aims: This study aims to compare the efficacy in alleviating pain between intracanal medicaments, namely Nitrofurantoin and Calcium Hydroxide Paste.
Study Design: Randomized Controlled Trial.
Place and Duration of Study: Sample: Department of Operative Dentistry, Sir Syed College of Medical Sciences, Pakistan, between January 2021 and May 2021.
Methodology: 60 patients were randomly divided into 3 groups, each group having 20 patients as following: Group 1: Nitrofurantoin, Group 2: Calcium Hydroxide and Group 3: Control. Preoperative pain was recorded using a numerical pain scale. After access preparation, chemomechanical preparation was performed with subsequent placement of intracanal medicaments. Pre-operative pain score was initially recorded, followed by post-operative pain at 12, 24, 48, and 72 hours, respectively. Root canal treatment was performed in single rooted teeth with patients suffering from symptomatic irreversible pulpitis
Results: Majority of the patients in all 3 groups were initially presented with moderate to severe pre-operative pain. After 72 hours post-operatively, 50% patients in Group 1 reported no pain, while 5% patients in both Group 2 and 3 had no pain. Pain significantly subsided in Group 1 as compared to Group 2 and 3. Regarding age and gender, both had no significant relationship with the pain scores in all of the 3 groups
Conclusion: Nitrofurantoin has been proven to be an effective intracanal medicament in alleviating immediate post-operative pain in patients with symptomatic irreversible pulpitis as compared to calcium hydroxide. While the control group with no intracanal medicament showed little reduction in pain scores. So, nitrofurantoin can be used as a substitute to currently available standard intracanal medicaments.

AbstractIn this work, high‐quality 1D van der Waals (vdW) Nb2Pd3Se8 is synthesized, showing an excellent scalability from bulk to single‐ribbon due to weakly bonded repeating unit ribbons. The calculation of electronic band structures confirmed that this novel Nb2Pd3Se8 is a semiconducting material, displaying indirect‐to‐direct bandgap transition with decreasing the number of unit‐ribbons from bulk to single. Field effect transistors (FETs) fabricated on the mechanically exfoliated Nb2Pd3Se8 nanowires exhibit n‐type transport characteristics at room temperature, resulting in the values for the electron mobility and Ion/Ioff ratio of 31 cm2 V−1 s−1 and ≈104, respectively. Through transport measurements at various temperatures from room temperature down to 90 K, it is confirmed that Nb2Pd3Se8 FETs can achieve negligible Schottky barrier height (SBH) for the Au contacts at the temperature range, displaying clear ohmic contact characteristics. Furthermore, top‐gated FETs fabricated with the Al2O3 dielectric layer are studied simultaneously with back‐gated FETs.
Amorphous VO2: A Pseudocapacitive Platform for High‐Rate Symmetric Batteries

Published: October 2021

AbstractAmong the various VO2 polymorphs, the layered compound, VO2(B), has been the most widely investigated lithium‐ion battery electrode material. For sodium‐ion electrodes, however, an amorphous solid may be more advantageous as a result of the open framework to facilitate ion insertion and the ability to tolerate volumetric changes. Herein, it is shown that the Na+ insertion properties of amorphous VO2 (a‐VO2) are superior to those of crystalline VO2(B). Amorphous VO2 exhibits a linear voltage characteristic over a 3 V range (4.0 to 1.0 V vs Na/Na+) leading to a reversible capacity as high as 400 mAh g−1 and rapid redox kinetics, which is attributed to its pseudocapacitive nature. The linear voltage characteristic over 3 V affords the opportunity of fabricating a symmetric Na‐ion battery in which the a‐VO2 material serves as both the positive electrode and the negative electrode. Such a symmetric battery offers safer operation in terms of overcharging, overdischarging, polarity reversal, high charge/discharge current abuse, and long‐term usage. The results suggest that amorphous transition metal oxides may offer advantageous attributes for rapid, safe, and energy‐dense storage.

AbstractOsteoarthritis (OA) is a musculoskeletal disorder disease affecting about 500 million people worldwide and mesenchymal sem cells (MSCs) therapy has been demonstrated as a potential strategy to treat OA. However, the shear forces during direct injection and the harsher shear condition of OA environments would lead to significant cell damage and inhibit the therapeutic efficacy. Herein, DNA supramolecular hydrogel has been applied as delivering material for MSCs to treat severe OA model, which perform extraordinary protection in MSCs against the shear force both in vitro and in vivo. It is demonstrated that the DNA supramolecular hydrogel can promote formation of quality cartilage, reduce osteophyte, and normalize subchondral bone under the high friction condition of OA, whose molecular mechanisms underlying therapeutic effects are also investigated. It can be anticipated that DNA supramolecular hydrogel would be a promising cell delivery system for multiple potential MSCs therapy.

AbstractIntroductionAmyloid beta (Aβ), tau, and neurodegeneration jointly with the Alzheimer's disease (AD) risk factors affect the severity of clinical symptoms and disease progression.MethodsWithin 248 Aβ‐positive elderly with and without cognitive impairment and dementia, partial least squares structural equation pathway modeling was used to assess the direct and indirect effects of imaging biomarkers (global Aβ‐positron emission tomography [PET] uptake, regional tau‐PET uptake, and regional magnetic resonance imaging–based atrophy) and risk‐factors (age, sex, education, apolipoprotein E [APOE], and white‐matter lesions) on cross‐sectional cognitive impairment and longitudinal cognitive decline.ResultsSixteen percent of variance in cross‐sectional cognitive impairment was accounted for by Aβ, 46% to 47% by tau, and 25% to 29% by atrophy, although 53% to 58% of total variance in cognitive impairment was explained by incorporating mediated and direct effects of AD risk factors. The Aβ–tau–atrophy pathway accounted for 50% to 56% of variance in longitudinal cognitive decline while Aβ, tau, and atrophy independently explained 16%, 46% to 47%, and 25% to 29% of the variance, respectively.DiscussionThese findings emphasize that treatments that remove Aβ and completely stop downstream effects on tau and neurodegeneration would only be partially effective in slowing of cognitive decline or reversing cognitive impairment.

Published: October 2021

Comprehensive SummaryA novel, green, and transition‐metal‐free protocol for the facile modification of quinoline and isoquinoline derivatives is introduced, starting from readily available and environmentally benign quinoline and isoquinoline N‐oxides with propargylic alcohols in the presence of Na2S2O8 or K2S2O8 at 100 °C. The one‐pot transformation features the advantages of good functional group compatibility, short reaction time, operational simplicity, and highly efficient reaction system. This protocol, which produces water as the only byproduct, provides efficient and atom‐economical access to a class of fascinating quinoline and isoquinoline products in satisfactory yields. The method is effective on the gram scale, thus highlighting the inherent practicality of this methodology.

AbstractNatural killer (NK) cells preferentially accumulate at maternal–foetal interface and are believed to play vital immune‐modulatory roles during early pregnancy and related immunological dysfunction may result in pregnant failure such as recurrent miscarriage (RM). However, the mechanisms underlying the establishment of maternal–foetal immunotolerance are complex but clarifying the roles of decidual NK (dNK) cells offers the potential to design immunotherapeutic strategies to assist RM patients. In this report, we analysed RNA sequencing on peripheral NK (pNK) and decidual NK cells during early pregnancy; we identified an immunomodulatory dNK subset CXCR4+CD56brightdNK and investigated its origin and phenotypic and functional characteristics. CXCR4+CD56brightdNK displayed a less activated and cytotoxic phenotype but an enhanced immunomodulatory potential relative to the CXCR4 negative subset. CXCR4+CD56brightdNK promote Th2 shift in an IL‐4‐dependent manner and can be recruited from peripheral blood and reprogramed by trophoblasts, as an active participant in the establishment of immune‐tolerance during early pregnancy. Diminished CXCR4+ dNK cells and their impaired ability to induce Th2 differentiation were found in RM patients and mouse models of spontaneous abortion. Moreover, adoptive transfer of CXCR4+ dNK cells to NK‐deficient (Nfil3–/–) mice showed great therapeutic potential of CXCR4+ dNK via recovering the Th2/Th1 bias and reducing embryo resorption rates. The identification of this new dNK cell subset may lay the foundation for understanding NK cell mechanisms in early pregnancy and provide potential prognostic factors for the diagnosis and therapy of RM.
Can the impact of canopy trees on soil and understory be altered using litter additions?
Authors: Yelenik Stephanie G. , Rehm Evan M. , D'Antonio Carla M. 
Published: October 2021

AbstractTrees can have large effects on soil nutrients in ways that alter succession, particularly in the case of nitrogen‐(N)‐fixing trees. In Hawaiʻi, forest restoration relies heavily on use of a native N‐fixing tree, Acacia koa (koa), but this species increases soil‐available N and likely facilitates competitive dominance of exotic pasture grasses. In contrast, Metrosideros polymorpha (‘ōhi‘a), the dominant native tree in Hawaiʻi, is less often planted because it is slow growing; yet it is typically associated with lower soil N and grass biomass, and greater native understory recruitment. We experimentally tested whether it is possible to reverse high soil N under koa by adding ‘ōhi‘a litter, using additions of koa litter or no litter as controls, over 2.5 yr. We then quantified natural litterfall and decomposition rates of ‘ōhi‘a and koa litter to place litter additions in perspective. Finally, we quantified whether litter additions altered grass biomass and if this had effects on native outplants. Adding ‘ōhi‘a litter increased soil carbon, but increased rather than decreased inorganic soil N pools. Contrary to expectations, koa litter decomposed more slowly than ‘ōhi‘a, although it released more N per unit of litter. We saw no reduction in grass biomass due to ‘ōhi‘a litter addition, and no change in native outplanted understory survival or growth. We conclude that the high N soil conditions under koa are difficult to reverse. However, we also found that outplanted native woody species were able to decrease exotic grass biomass over time, regardless of the litter environment, making this a better strategy for lowering exotic species impacts.
