Six years of E-JournALL. Reflections on open access, international, multilingual applied linguistics publishing

E-JournALL, EuroAmerican Journal of Applied Linguistics and Languages published its first issue in November 2014. The journal was meant to be a bridge: between scholars working in Europe and the Americas; between scholars writing in English, Italian, and Spanish; and between scholars publishing in the journal and researchers and language teachers across the world with or without university-paid access to expensive journal subscriptions. The journal was founded, therefore, on three pillars: internationalism, multilingualism, and open access. In this reflection, written at the end of our sixth year as a journal—and with the release of our 12th issue and 97th article—we look back on the last six years, taking stock of how well we have lived up to our founding principles, and we look ahead to the journal’s next six years

(Re)presenting Science in Research Articles and Press Releases

Science communication is a powerful supplier of scientific knowledge for the public (see Harmatiy 2021; Kueffer and Larson 2014). While popularization discourse has been explored in depth (see for example, Calsamiglia and Van Dijk 2004; Garzone 2014, 2020; Gotti 2014; Luzón 2013; Myers 2003), the ways specific linguistic strategies impact content and the communication of science still need to be fully explored. The general purpose of this study is to explore how titles of scientific articles are transformed to be turned into headlines of press releases. Specifically, it aims first to identify recurring discursive patterns in the adaptation of titles in scientific discourse to headlines in science communication. Second, it investigates whether these patterns have an impact on the way scientific knowledge is presented. Two matching corpora were used: one of titles of research articles and one of headlines of research-based university press releases. The unique feature of these two corpora is that they have a bijective relation, so that each of the 210 titles of scientific papers matches one of the 210 university press release headlines. Results show that many linguistic strategies in science journalism are the mirror image of scientific discourse: three strategies were identified that contribute to two different representations of science, as an ongoing process in academic titles and a conclusive fact in press releases’ headlines: 1) the validity-endorsement strategy; 2) the V-ing construction; 3) the opposition between unspecified association vs. explicit relation

Mídias sociais em tempos de bibliotecas 2.0: um estudo em Bibliotecas das instituições federais de ensino brasileiras trazendo perspectivas futuras para a preservação digital

This study aims to discuss the main challenges regarding the social participation on the Web by the Brazilian Federal Education Institutions’(IFES) Libraries and the changes related to the these institutions’ activities, especially interactions with their audience. The Research conducted a quantitative approach survey on the use of the main existing social media by these libraries. The survey sought to identify the level of involvement and participation of these libraries in social media. It is understood that this investigation is necessary as a foundation to the urgent need to raise awareness these Brazilian institutions as the valuable potential of interaction with their users through these media, despite the study demonstrated an incipient use. Based on the conducted survey, the study presents a reflection of the importance that it should devote to digital preservation, not only of their collections, but also the relevant records of the social media content. The results show that most brazilian public universities use Web 2.0 tools with social focus, and the greater adoption of Facebook (43%) and Twitter (29%), but only 5% of them use these medias to disseminate the collections. Thus, it was concluded that the use of social media by these libraries still have a lot to develop and consequently the digital preservation actions need to consider the inclusion of content generated by these media that increasingly have become a valuable communication channel

BackgroundEnergy intake is a key determinant of weight.ObjectiveOur objective was to examine trends in energy intake in adults in the United States from 1971\u20131975 to 2009\u20132010.DesignThe study was a trend analysis of 9 national surveys in the United States that included data from 63,761 adults aged 20\u201374 y.ResultsAdjusted mean energy intake increased from 1955 kcal/d during 1971\u20131975 to 2269 kcal/d during 2003\u20132004 and then declined to 2195 kcal/d during 2009\u20132010 (P-linear trend < 0.001, P-nonlinear trend < 0.001). During the period from 1999\u20132000 to 2009\u20132010, no significant linear trend in energy intake was observed (P = 0.058), but a significant nonlinear trend was noted (P = 0.042), indicating a downward trend in energy intake. Significant decreases in energy intake from 1999\u20132000 to 2009\u20132010 were noted for participants aged 20\u201339 y, men, women, and participants with a BMI (in kg/m2) of 18.5 to <25 and 6530.ConclusionAfter decades of increases, mean energy intake has decreased significantly since 2003\u20132004.20132015-10-09T00:00:00ZCC999999/Intramural CDC HHS/United States23426032PMC459894

DFT insights into the oxygen-assisted selective oxidation of benzyl alcohol on manganese dioxide catalysts

The reactivity pattern of the MnO2 catalyst in the selective aerobic oxidation of benzyl alcohol is assessed by density functional theory (DFT) analysis of adsorption energies and activation barriers on a model Mn4O8 cluster. DFT calculations predict high reactivity of defective Mn(IV) sites ruling a surface redox mechanism, L-H type, involving gas-phase oxygen. Bare and promoted (i.e., CeOx and FeOx) MnOx materials with high surface exposure of Mn(IV) sites were synthesized to assess kinetic and mechanistic issues of the selective aerobic oxidation of benzyl alcohol on real catalysts (T, 333- 363K). According to DFT predictions, the experimental study shows: i) comparable activity of bare and promoted catalysts due to surface Mn(IV) sites; ii) the catalytic role of oxygen-atoms in the neighboring of active Mn(IV) sites; and iii) a 0th-order dependence on alcohol concentration, diagnostic of remarkable influence of adsorption phenomena on the reactivity pattern. Evidences of catalyst deactivation due to the over-oxidation of benzyl alcohol to benzoic acid, acting as poison of the active sites, are discussed

The reliability of gait parameters captured via instrumented walkways: a systematic review and meta-analysis

Introduction: Electronic pressure-sensitive walkways are commonly available solutions to quantitatively assess gait parameters for clinical and research purposes. Many studies have evaluated their measurement properties in different conditions with variable findings. In order to be informed about the current evidence of their reliability for optimal clinical and scientific decision making, this systematic review provided a quantitative synthesis of the test-retest reliability and minimal detectable change of the captured gait parameters across different test conditions (single and cognitive dual-task conditions) and population groups. Evidence acquisition: A literature search was conducted in PubMed, Embase, and Scopus until November 2021 to identify articles that examined the test-retest reliability properties of the gait parameters captured by pressure-sensitive walkways (gait speed, cadence, stride length and time, double support time, base of support) in adult healthy individuals or patients. The methodological quality was rated using the "Consensus-based standards for the selection of health measurement instruments" checklist. Data were meta-analyzed on intraclass correlation coefficient to examine the test-retest relative reliability. Quantitative synthesis was performed for absolute reliability, examined by the weighted average of minimal detectable change values. Evidence synthesis: A total of 44 studies were included in this systematic review. The methodological quality was adequate in half of the included studies. The main finding was that pressure-sensitive walkways are reliable tools for objective assessment of spatial and temporal gait parameters both in singleand cognitive dual-task conditions. Despite few exceptions, the review identified intraclass correlation coefficient higher than 0.75 and minimal detectable change lower than 30%, demonstrating satisfactory relative and absolute reliability in all examined populations (healthy adults, elderly, patients with cognitive impairment, spinocerebellar ataxia type 14, Huntington's disease, multiple sclerosis, Parkinson's disease, rheumatoid arthritis, spinal cord injury, stroke or vestibular dysfunction). Conclusions: Current evidence suggested that, despite different populations and testing protocols used in the included studies, the test-retest reliability of the examined gait parameters was acceptable under single and cognitive dual-task conditions. Further high-quality studies with powered sample sizes are needed to examine the reliability findings of the currently understudied and unexplored pathologies and test conditions

Cuerpo discapacitado: sujeto de producción por actos tradicionales eficaces?

Acercamos ciertos interrogantes respecto de una “epistemología de la discapacidad”, con pregunta: ¿Si no estaremos reproduciendo la construcción de un conocimiento apartado, disgregado en alteridades de un saber “discapacitante” en las redes de formación al abordar el tema? Avances sobre las relaciones de poder disciplinar construidas sobre el/los cuerpo/s, han dado como resultado una producción de saber del “déficit “objetivando y adjetivando a ciertos sujetos en “discapacitados”, “anormales”, etc. Hoy día puesto en cuestión. El concepto de discapacidad es un concepto construido socialmente sobre el cual todos tenemos alguna idea al respecto, y que habla del modo en que los sujetos y grupos de una comunidad producen en un contexto socio histórico especifico, otorgando significados, interpretando la realidad cotidiana, creando y transformando conocimientos y prácticas. La educación en este sentido es una histórica constructora de discurso sobre la normalidad y el déficit.
