Unscented Kalman filter for airship model uncertainties and wind disturbance estimation
Authors: Wasim Muhammad , Ali Ahsan , Choudhry Mohammad Ahmad , Saleem Faisal , Shaikh Inam Ul Hasan , Iqbal Jamshed
Published: November 2021

An airship is lighter than an air vehicle with enormous potential in applications such as communication, aerial inspection, border surveillance, and precision agriculture. An airship model is made up of dynamic, aerodynamic, aerostatic, and propulsive forces. However, the computation of aerodynamic forces remained a challenge. In addition to aerodynamic model deficiencies, airship mass matrix suffers from parameter variations. Moreover, due to the lighter-than-air nature, it is also susceptible to wind disturbances. These modeling issues are the key challenges in developing an efficient autonomous flight controller for an airship. This article proposes a unified estimation method for airship states, model uncertainties, and wind disturbance estimation using Unscented Kalman Filter (UKF). The proposed method is based on a lumped model uncertainty vector that unifies model uncertainties and wind disturbances in a single vector. The airship model is extended by incorporating six auxiliary state variables into the lumped model uncertainty vector. The performance of the proposed methodology is evaluated using a nonlinear simulation model of a custom-developed UETT airship and is validated by conducting a kind of error analysis. For comparative studies, EKF estimator is also developed. The results show the performance superiority of the proposed estimator over EKF; however, the proposed estimator is a bit expensive on computational grounds. However, as per the requirements of the current application, the proposed estimator can be a preferred choice.
Characterization of the endometrial, cervicovaginal and anorectal microbiota in post-menopausal women with endometrioid and serous endometrial cancers
Authors: Gressel Gregory M. , Usyk Mykhaylo , Frimer Marina , Kuo D. Y. S. , Burk Robert D.
Published: November 2021

Objective

To characterize the microbiota of postmenopausal women undergoing hysterectomy for endometrioid (EAC) or uterine serous cancers (USC) compared to controls with non-malignant conditions.

Methods

Endometrial, cervicovaginal and anorectal microbial swabs were obtained from 35 postmenopausal women (10 controls, 14 EAC and 11 USC) undergoing hysterectomy. Extracted DNA was PCR amplified using barcoded 16S rRNA gene V4 primers. Sequenced libraries were processed using QIIME2. Phyloseq was used to calculate α- and β- diversity measures. Biomarkers associated with case status were identified using ANCOM after adjustment for patient age, race and BMI. PICRUSt was used to identify microbial pathways associated with case status.

Results

Beta-diversity of microbial communities across each niche was significantly different (R2 = 0.25, p < 0.001). Alpha-diversity of the uterine microbiome was reduced in USC (Chao1, p = 0.004 and Fisher, p = 0.007) compared to EAC. Biomarkers from the three anatomical sites allowed samples to be clustered into two distinct clades that distinguished controls from USC cases (p = 0.042). The USC group was defined by 13 bacterial taxa across the three sites (W-stat>10, FDR<0.05) including depletion of cervicovaginal Lactobacillus and elevation of uterine Pseudomonas. PICRUSTt analysis revealed highly significant differences between the USC-associated clades within the cervicovaginal and uterine microbiota.

Conclusions

The microbial diversity of anatomic niches in postmenopausal women with EAC and USC is different compared to controls. Multiple bacteria are associated with USC case status including elevated levels of cervicovaginal Lactobacillus, depletion of uterine Pseudomonas, and substantially different functional potentials identified within cervicovaginal and uterine niches.
Effect of different Kinesio tape tensions on experimentally-induced thermal and muscle pain in healthy adults
Authors: Naugle Keith E. , Hackett Jason , Aqeel Dania , Naugle Kelly M.
Published: November 2021

Athletes and rehabilitation specialists have used Kinesio tape (KT) to help alleviate pain symptoms. Currently, no clear mechanism exists as to why pain is relieved with the use of KT and whether the pain relieving effect is simply a placebo effect. Additionally, the most effective taping parameters (tension of tape) for pain reduction remain unknown. We used quantitative sensory testing to address these key gaps in the KT and pain literature. Using a repeated-measures laboratory design, we examined whether KT applied at different tensions reduces experimentally-induced pain compared to a no tape condition and KT with minimal tension. Heat pain thresholds (HPT’s), pressure pain thresholds (PPT’s), and pressure pain suprathreshold (PPS: 125% of PPT) tests were administered to the forearm prior to and during KT and no tape conditions. Tape was applied to the ventral forearm at 25% of max tension, 75% of max tension, and no tension (placebo). Repeated measures ANOVA’s evaluated the pain outcomes between conditions and across time. KT had no significant effect on PPT’s and HPT’s (p’s >0.05). The ANOVA on PPS revealed that KT applied at 25% of tension significantly reduced pain ratings from the pretest (M = 34.4, SE = 5.5) to post-test 1 (M = 30.3, SE = 4.7) and post-test 2 (M = 30.4, SE = 4.7). No other conditions significantly reduced suprathreshold pressure pain. However, pain ratings at posttest-1 during the no-tape condition (M = 36.4, SE = 5.3) were significantly greater than pain ratings during post-test 1 and post-test 2 of all three tape conditions. In conclusion, the current study revealed that KT applied at low tension is the optimal tension to reduce pressure-evoked muscle pain. Additionally, the results suggested that KT applied at low, high, or no tension may acutely prevent increased muscle sensitivity with repeated pressure stimulation.

Authors: Zhou Ning , Ho Jean-Pierre T. F. , Klop Cornelis , Schreurs Ruud , Beenen Ludo F. M. , Aarab Ghizlane , de Lange Jan
Published: November 2021

The aims of this study were (1) to quantify the intra-individual variation in the upper airway measurements on supine computed tomography (CT) scans at two different time points; and (2) to identify the most stable parameters of the upper airway measurements over time. Ten subjects with paired CT datasets (3–6 months interval) were studied, using computer software to segment and measure the upper airway. The minimum cross-sectional area of the total airway and all its segments (velopharynx, oropharynx, tongue base, and epiglottis) generally had the largest variation, while the length of the total airway had the lowest variation. Sphericity was the only parameter that was stable over time (relative difference <15%), both in the total airway and each subregion. There was considerable intra-individual variation in CT measurements of the upper airway, with the same patient instruction protocol for image acquisitions. The length of the total airway, and the sphericity of the total upper airway and each segment were stable over time. Hence, such intra-individual variation should be taken into account when interpreting and comparing upper airway evaluation parameters on CT in order to quantify treatment results or disease progress.
Pandemic, censorship and creative protests via grassroots visual mobilization
Authors: Wang Meiqin
Published: November 2021

In early 2020, Chinese people engaged in several rounds of extraordinary online campaigns in response to the government’s handling of the outbreak of coronavirus. During these campaigns, visual images played a crucial role in facilitating netizens to inform each other, escape official censoring machinery, express anger and frustration, excavate truth, document reality and mobilize online support and protest. In particular, images related with Dr Li Wenliang, one of whistle-blowers of the soon-to-be pandemic who himself died of the virus, and Dr Ai Fen, the first doctor to share information about a possible coronavirus diagnose among her colleagues, became the focal points of the unprecedented online mobilization successively. Millions of netizens participated in the effort to circulate these images (and stories behind them) and invented ingenious ways to continue the endeavour when confronted by the heightened censorship. Various art communities and individuals have done their share to fuel in this momentum of visual mobilization and there was a surge of call for public participation in responding to the pandemic through participatory public artworks. Maskbook, initiated by artist Wen Fang, and One More Day led by MeDoc, are two exemplary cases. Through analysing these images, this article discusses China’s grassroots visual mobilization to claim for freedom of speech and access to truth in the wake of the massive health crisis and articulates its contribution to the formation of a bottom-up visual discourse that challenges the state’s media discourse in interpreting the pandemic as a victory of government leadership.
Pericoronial writing from China and the diaspora
Authors: Chambers Claire
Published: November 2021

This article analyses what Margaret Atwood calls the literature of ‘ustopia’. The portmanteau term brings together the utopia and dystopia categories because Atwood argues that one contains the germ of the other. Ustopian writing is a body of work that is helpful when it comes to understanding current destruction to lives and livelihoods, and imagining our post-coronavirus future. The present article thus explores four works of ustopian writing from China and the diaspora, three of them having been written before the current COVID-19 crisis but all shedding light on it. Fang Fang’sWuhan Diary(2020) represents the first real work of postcoronial literature in what seems likely to be an outpouring over the coming years. It is anticipated very ably by the precoronial texts also analysed here – Mo Yan’sFrog([2009] 2014), Ma Jian’sChina Dream(2018) and Ling Ma’sSeverance(2018) – which presage the post-COVID dispensation. Taken together, they form a body of work that the article terms pericoronial writing.
Make this tango viral: Touching toward the untouchable in tele-synaesthesia performance
Authors: Hao Ada Xiaoyu
Published: November 2021

The COVID-19 pandemic has created an uncanny rift between tact and touch as it expands the virtual towards its potential. Layer upon layer of new information has been repeatedly revising and reformulating our sense of touch. The unconditional freedom of touch needs to be rendered accountable in this rift of time and space. The act of touching entails individual acknowledging the risk of reaching towards the unknown or the known. Tracing with a tactile sense of touch is to be tactful about how, where and what can such act of touching could reach, especially in the context of communicative technology. This article focuses on the possibility of virtual sensibility by challenging ways to feel touched beyond the nostalgic narratives that attempt to indict communicative technology with the loss of touch. To replenish and reinstate touch through tele-synaesthesia performance, I ask: how to elongate our somatosensensation and echo the embodied experience of touching through virtual connectivity? Tele-synaesthesia performance joints telematic and synaesthetic experience together to embody the incorporeality of touch through virtual connectivity. It embodies the injunction of physical contact and challenges what can and cannot be touched by suturing one sensuous modality to another. Inspired by Paul Sermon’s artistic production of Telematic Quarantine (2020) and Pandemic Encounters (2020), that tele-presents the stories of self (isolation), I have created The Best Facial (2021): a series of one-to-one participatory tele-synaesthesia performances, where I became a virtual aesthetician and performed ‘virtual facial care’ on Zoom amid the second wave of the pandemic in the United Kingdom. In this article, I will discuss how tele-synaesthesia performance could trigger tactile experiences in the participants in reference to Michel Foucault’s concept Heterotopia (1986) that allegorically address the incompatible physical places in the society. I discuss how to elicit an affective sensory response from non-tactile senses through virtual touch, as stated by Naomi Bennett’s ‘Telematic connections: sensing, feeling, being in space together’ (2020). I refer to Legacy Russell’s discussion on glitch (2020) to analyse the possible future of tele-synaesthesia performance and its potential for expanding virtual connectivity with an ethical touch of a non-performative refusal of the present.
The homesick and the sick home
Authors: Holdsworth Amy
Published: November 2021

This short article explores the popular property renovation series DIY SOS: The Big Build () to examine what it can tell us about the textual, affective and political modes of nostalgia on television. Inverting the homesick at the heart of nostalgia it considers, instead, the idea of the sick home by examining the ways in which the series represents and remedies lives affected by chronic illness and/or disability. The nostalgic promise of The Big Build is of a home to return to in the future and I argue that by placing the programme within the context of the COVID-19 pandemic, the series reveals a complex dynamic of loss and recuperation and a powerful nostalgic fantasy of community, care and (public service) television.
A woman scientist in pursuit of truth: A rising trend of representation with Chernobyl
Authors: Tunç Aslı
Published: November 2021

Sky/HBO’s miniseries Chernobyl (2019) tells a human story behind the catastrophic disaster that had begun with an explosion at the Chernobyl Nuclear Power Plant in Soviet Ukraine on 26 April 1986. Over the course of five one-hour episodes, Chernobyl dramatizes the incidents that paved the way to the massive explosion, such as the Cold War era, the dysfunctional Soviet bureaucracy and the power issues among the male political and scientific establishment. The highlight of the miniseries is female agency being the symbol of scientific approach, rational thought and common sense. This article analyses Chernobyl and the character of a Belarusian nuclear physicist named Ulyana Khomyuk (played by Emily Watson) by focusing on women’s representation on popular television in science, technology, engineering and mathematics (STEM) fields. It also questions whether Chernobyl is one of the very few examples in popular culture of changing patterns of women’s representation in STEM.
El narcotráfico en el cine mexicano: arquetipos desde 2010 a 2017
Authors: Díaz-Cerveró Elba , Domínguez-Partida Gabriel
Published: November 2021

This article studies the archetypes and the iconography in contemporary Mexican films that deal with drug trafficking in order to examine the evolution of the narco cinema subgenre and changes in the representation of the narcocultura. The corpus is constituted by the biggest box office hits each year between 2010 and 2017, which are analysed thematically. This study suggests that the characteristics of the narcocultura continue circulating within Mexican cinema, but it does not point to a subgenre’s existence. The genres circumscribing the films analysed promote the narcos’ heroism via archetypes and iconography, which symbolize how narcos overcome their modus vivendi to stand as a legitimate authority against a corrupt government. Alongside this representation of narcos, these films also present objectified women and promote values such as loyalty and family. The aforementioned archetypes and iconography offer a view of life in which violence is normalized, and crime is seen as a legitimate lifestyle.

Politeness in 13–16th Century Catalan
Authors: Nagy C. Katalin
Published: November 2021

The present study aims to discuss some politeness strategies in 13–16th century Catalan, based on a corpus pragmatic analysis of requests from the Computerized Corpus of Old Catalan (Corpus Informatitzat del Català Antic [CICA]), found by searching for occurrences of the speech act verbs pregar ‘ask, pray’ and suplicar ‘supplicate, beg, beseech’. Results of the present study provide evidence that politeness in 13–16th century Catalan was realized by different linguistic means than in contemporary Catalan. It focuses on some conventionally indirect strategies that consisted in using the verb voler ‘want’ to transfer the imperative force from the performance of the requested act to the hearer’s willingness. At the intersection of speech act research, politeness studies, historical pragmatics and corpus pragmatics, this study also discusses some methodological challenges of these areas.
A holland kór azonosítása aszimmetrikus kointegráció segítségével szubszaharai afrikai és dél - amerikai országok esetén
Authors:   , Barczikay Tamás Gábor
Published: November 2021

Doktori értekezésemben az úgynevezett holland kór jelenségét vizsgáltam meg szubszaharai afrikai (Tanzánia, Angola és Botswana) és dél-amerikai (Peru, Chile és Bolívia) országok esetén. A jelenség lényege, hogy nyersanyagfelfedezések hatására a beáramló külföldi működőtőke miatt felértékelődhet egy ország hazai fizetőeszköze, ami hosszú távon rontja egyéb exportszektorainak nemzetközi versenyképességét és azok leépüléséhez vezet. Négy feltett kutatási kérdésemre úgynevezett nemlineáris autoregresszív osztott késleltetésű (NARDL) modellek segítségével válaszoltam, melyeket aszimmetrikus kointegráció tesztelésére használtam. Megállapítottam, hogy amennyiben kointegráló kapcsolat van egy ország reál-effektív árfolyama (REER) és az általa exportált nyersanyag világpiaci reálára között, akkor az adott ország holland kórban szenved. Ezen felül, amennyiben reálárfolyamra (RER) cseréljük a REER-t és hasonló összefüggést találunk, akkor a jelenséget parciális holland kórnak nevezhetjük. Az eljárás több szempontból is újszerűnek tekinthető: 1. Egyrészt az adatok korlátozott mennyisége miatt más eljárással megbízhatóan nem végezhetőek el ilyen jellegű számítások. 2. Másrészt figyelembe vettem a sokkok esetleges aszimmetrikus hatását is. A vizsgált hat ország segítségével a következő megállapításokat tettem kutatási kérdéseimmel kapcsolatban: 1. Kérdés volt, hogy az eljárás alkalmas-e parciális szinten a holland kór kimutatására? Ezzel kapcsolatban arra jutottam, hogy NARDL modellek segítségével könnyen azonosítható a parciális holland kór jelensége. 2. Ezt kibővítettem továbbá azzal a megállapítással, hogy amennyiben a hatás a REER modellben kimutatható, nagy valószínűséggel a RER modellben is az lesz (második kérdés), azaz nincs „összemosó hatás”. 3. A jelenség aszimmetriájára vonatkozóan csak Perunál találtam igazoló eredményt, de ezt fenntartásokkal kell kezelni, mert a globális – és a parciális modellben a hosszú távú paraméterbecslések ellentétes relációban voltak egymással (harmadik kérdés). 4. Végezetül nyitott kérdésént feltettem, hogy milyen tényezők befolyásolhatják a holland kór kialakulását és súlyosságát? Ezzel kapcsolatban az a meglátásom, hogy kizárólag kereskedelmi vagy politikai/intézményi okokkal a probléma mélysége nem magyarázható. Eltérő gazdaságpolitikai mixek és a jelenség tudatos monitorozása lehetnek megoldások a kárcsökkentésre. A gazdaságpolitikai mixben a vizsgált országok alapján pedig a monetáris politikáé a főszerep. A gazdasági okokon felül érdemes kerülni a túlzott egyoldalú függést más országoktól, mivel azok erőfölényüket politikai hatalommá képesek transzformálni.

Published: November 2021

: The purpose of this study is to evaluate the implementation of the programs in distance education through the Education Information Network (EBA) platform due to the Covid-19 pandemic according to teachers’ opinions. In the study, the case study method, one of the qualitative research methods, was used. A semi-structured questionnaire with open-ended questions was given to 107 teachers. The data obtained were examined using content analysis. According to the study results, in “EBA Internet” and “EBA Live Class,” teachers stated that not having information about activities suitable for distance education and limited interaction with students were the difficulties they have faced. The teachers stated that the contents in the EBA are suitable for the targeted learning outcomes. Still, they are qualitatively simple, insufficient, and most of them cannot be accessed. They also stated that they had difficulty carrying out assessment and evaluation in their teaching activities due to insufficient measurement content suitable for the class level in the EBA platform. The students did not want to answer the questions in distance education courses. In addition, teachers suggested that learning with games, movies, songs, visuals, experiments, and STEM activities should be added for the programs to be implemented more efficiently on the EBA platform. Furthermore, an application that makes the board more practical and useful in live lessons should be created.

Published: November 2021

Background Capsular contracture is a frequent complication of breast augmentation that constitutes one of the most common reasons for secondary operations. Capsular contracture is treated surgically, often with total capsulectomy. Therefore, in this study, we aimed to study correlations among intraoperative observations, physical examination findings, and characteristics of the previous operation in patients with capsular contracture who underwent total capsulectomy.Methods A retrospective chart review was conducted for patients treated from May 2017 to April 2019, analyzing 24 breasts in 12 female patients. The patients were classified in terms of the Baker grade, incision type, implant type, and implant plane. During the operation, we evaluated the ease of dissection based on intraoperative features such as anterior and posterior wall dissection, bleeding tendency, and scar length. Statistical analysis was performed to identify association between variablesResults The implant was changed in eight patients, while only explantation was performed in the remaining four patients. The ease of capsule dissection had a proportional correlation with the Baker grade (P=0.005). Intraoperative dissection was significantly easier in the inframammary fold (IMF) group than in the periareolar group (P=0.035).Conclusions An IMF incision is preferable for planning en bloc capsulectomy. However, for aesthetic concerns, a periareolar incision would be preferable. In addition, a lower Baker grade (grade I or II) was associated with easier dissection. Therefore, surgeons should choose the incision type depending on the necessity of performing en bloc capsulectomy, Baker grade, and scar length.

Published: November 2021

This study explores the relationship between technology adoption and attitudes toward gender equality in political representation by relying on diffusion theories coupled with frameworks of ideational change, social interaction, and world society. We examine whether the use of mobile phones shapes gender attitudes toward women’s participation in politics by making it more widely accepted that women hold institutional roles. We do so with micro-level data from the AfroBarometer, covering 36 African countries, and a multilevel modeling approach. Our results suggest that regular use of mobile phones is associated with more positive attitudes toward women’s participation in politics. The significant relationship—robust to the use of instrumental variable techniques—is observed only among women. This finding strengthens the idea that technology adoption on the part of women, by improving connectivity and expanding access to information, may be a successful lever to raise women’s status and promote societal well-being, ultimately contributing to achieving Sustainable Development Goal 5, which seeks to “achieve gender equality and empower all women and girls.” Concurrently, the lack of a significant relationship for men highlights an important yet often neglected issue: policies aimed at changing gender attitudes are often targeted at women, but men’s attitudes can be stickier than women’s, thus requiring further efforts.

An investigation was conducted of the modification of bamboo fibers (BF) by nano-hydroxyapatite (N-HA) and its impact on the mechanical and thermal properties of BF/PLA composites. The functional groups, and crystallinity of the N-HA modified BF were investigated with Fourier transform infrared (FTIR) spectroscopy and X-ray diffraction (XRD), respectively. The effects of different N-HA contents on the properties of the BF/PLA composites were evaluated using mechanical testing (bending, tensile, and impact properties), differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), and scanning electron microscopy (SEM). The results showed that the most suitable N-HA content was 7.5 wt.%. Treating BF with an optimum concentration of N-HA decreased the polarity of the bamboo fiber, while maintaining the crystal structure of the cellulose. Compared with the control group, the mechanical properties and the crystallinity of the modified BF/PLA composites were improved, and the flexural, tensile, and impact strengths increased by 10.2%, 11.6%, and 28.1%, respectively. The thermogravimetric analysis results indicated modified BF/PLA composites has higher thermal stability.

Peripheral nerve injuries in children can result in devastating lifelong deficits. Because of the time-sensitive nature of muscle viability and the limited speed of nerve regeneration, early recognition and treatment of nerve injuries are essential to restore function. Innovative surgical techniques have been developed to combat the regenerative length and speed; these include nerve transfers. Nerve transfers involve transferring a healthy, expendable donor nerve to an injured nerve to restore movement and sensation. Nerve transfers are frequently used to treat children affected by conditions, including UE trauma, brachial plexus birth injury, and acute flaccid myelitis. Pediatricians play an important role in the outcomes of children with these conditions through early diagnosis and timely referrals. With this review, we aim to provide awareness of state-of-the-art surgical treatment options that significantly improve the function of children with traumatic nerve injuries, brachial plexus birth injury, and acute flaccid myelitis.

Published: November 2021

AF has been consistently associated with multiple forms of dementia, including idiopathic dementia. Outcomes after catheter ablation for AF are favourable and patients experience a better quality of life, arrhythmia-free survival, and lower rates of hospitalisation compared to patients treated with antiarrhythmic drugs. Catheter ablation is consistently associated with lower rates of stroke compared to AF management without ablation in large national and healthcare system databases. Multiple observational trials have shown that catheter ablation is also associated with a lower risk of cognitive decline, dementia and improved cognitive testing that can be explained through a variety of pathways. Long-term, adequately powered, randomised trials are required to define the role of catheter ablation in the management of AF as a means to lower the risk of cognitive decline, stroke and dementia.
A saúde pública para além do debate entre direito e meritocracia

Published: November 2021

Este artigo discute a ressignificação de parte da saúde pública a partir da realidade posta pela COVID-19. Na primeira parte, é tratada a evolução da concepção da saúde como um direito, inserido no âmbito da seguridade social, em diversos países, desde o final do século XIX. Na segunda, são apontadas as críticas do pensamento neoliberal aos gastos públicos com a saúde, desde a crise dos anos 1970. Já na terceira, apresentamos os argumentos que nos levam a defender que parte da saúde pública pode estar sendo ressignificada, para além do direito cidadão ou meritocrático. Entre esses argumentos, destacamos que, a crise econômica e sanitária que acompanhou o avanço da COVID-19, ao deixar claro que esta não será a última pandemia que iremos enfrentar, recolocou a saúde pública no centro da discussão, mas agora como elemento chave para a garantia da soberania nacional e da coesão social, essenciais à continuidade do processo de acumulação na mundialização do capital. Para isso, foi feita revisão da literatura de textos que colocam o acesso à saúde a partir de uma perspectiva histórica crítica e acompanhamento dos desdobramentos da crise sanitária decorrente da COVID-19.
Imaginários distópicos, populismos e política pop
Authors: Prior Hélder
Published: November 2021

No seguinte ensaio pretendemos analisar como o episódio “The Waldo Moment”, da série britânica Black Mirror, possibilita uma reflexão crítica acerca da emergência dos populismos contemporâneos e do papel dos meios de comunicação nessa emergência. Assim, na primeira parte traçamos um panorama acerca do fenómeno do populismo, apresentando as principais conceptualizações sobre o conceito, bem como alguns desafios que a democracia liberal enfrenta. Posteriormente, verificamos algumas condições actuais da democracia em tempos de indignação e de desprezo pela classe política. Por fim, apresentamos uma análise hermenêutica ao episódio “The Waldo Moment”, acreditando que este nos possibilita compreender alguns aspectos da paisagem política contemporânea permeada pelo avanço dos populismos reaccionários.
A pioneira se despede
Authors: Pieranti Octavio Penna
Published: November 2021

Em 17 de julho 1980, o governo federal decretou o fim da TV Tupi, ao não renovar sete de suas nove outorgas. No ano seguinte, viabilizou a criação de duas novas redes de televisão, SBT e Manchete, que, com as frequências antes usadas pela TV Tupi, vieram, na prática, a substitui-la. O objetivo deste artigo é resgatar o último mês da rede pioneira da televisão brasileira, com base em documentos do governo federal e, mais especificamente, produzidos por unidades vinculadas ao seu Serviço Nacional de Informações (SNI). Mesmo públicos, esses documentos não são de conhecimento, nem de uso comum. Assim, este artigo contribui para a reanálise de um caso central para a radiodifusão brasileira na década de 1980, bem como para a preservação da memória da TV Tupi e da administração pública.
Article numbers as a leading indicator of publication time
Authors: Leppink Jimmie
Published: November 2021

Aims: in health professions education (HPE), the use of statistics is commonly associated with somewhat larger samples, whereas smaller samples or single subjects (i.e., N = 1) are usually labelled as needing some kind of ‘qualitative’ approach. However, statistical methods can be very useful in small samples and for individual subjects as well, especially where we have time series of repeated measurements of the same outcome variable(s) of interest. The aim of this article is twofold: to demonstrate an example of a cross-correlation function for single subjects in a HPE context and to suggest a few settings in HPE where this cross-correlation function can be of use.Method: the example uses data from a recent Open Access publication on among others article numbers and publication time in a number of major HPE journals to examine the relation between the number of articles published and median publication time over time in the zero-cost Open-Source statistical program R version 4.0.5.Results: as to be expected, the number of articles published appears somewhat of a leading indicator of publication time: both number of articles in year ‘y’ and number of articles in year ‘y minus 1’ correlate > 0.6 with median publication time in year ‘y’, while correlations of other time differences (e.g., number of articles in year ‘y minus 2’ and median publication time in year ‘y’, or median publication time in year ‘y’ and number of articles in year ‘y plus 1’) are substantially smaller.Conclusion: in line with recent literature, this article demonstrates that the cross-correlation function can be used in the context of small samples and single subjects. While the example focusses on article numbers and publication times, it can equally be applied in for example studying relations between knowledge, skills and attitude in individuals, or relations between behaviors of individuals working in pairs or small groups.
O lugar da tradução no ensino-aprendizagem de inglês do século XXI
Authors: Selhorst Lucas Alves
Published: November 2021

Em que pese as críticas que podem ser feitas ao uso da tradução no ensino-aprendizagem de inglês, ela ainda é muito usada, de diferentes formas. Considerando as controvérsias desse tema, essa é uma pesquisa bibliográfica que tem o objetivo de entender o lugar da tradução no processo de ensino-aprendizagem de língua inglesa do século XXI. Para além dos livros e trabalhos científicos, também buscou-se olhar para a Base Nacional Comum Curricular (BNCC), já que esse é o documento normativo mais recente para a elaboração de currículos e de propostas pedagógicas no Brasil. A tradução como método apresenta fragilidades, considerando que a capacidade dos métodos de serem suficientes frente aos diversos desafios que se impõem vem sendo questionada, esse, o mais antigo, pode ser visto como uma herança que já não faz mais sentido. Já como recurso, se verificou que a tradução se situa melhor. Podendo colaborar para o aprendizado da língua inglesa, para o desenvolvimento de percepções linguísticas, e da consciência que envolve diversos aspectos tanto da língua inglesa, quanto da língua materna, desde que seja pensada como um recurso significativo, atual, contextualizado e que leve em conta as particularidades e necessidades dos alunos.
Corrosion of ISG by Mg-Si precipitation in presence of Ankerite
Authors: Al Dabbas Ali , Kopecskó Katalin
Published: November 2021

Contact with groundwater in the disposal geological site will induce the creation of an amorphous corrosion layer on the high-level radioactive glass. This is connected to silicate saturation conditions in the surrounding medium, and it is influenced significantly by geochemical processes in the near-field minerals at that depth. The international simple glass is a six-oxide borosilicate glass that is commonly used in nuclear interest. It is a simple glass generated from its composition to be an international benchmark glass. The results of the standard materials characterization center leaching tests in double deionized water at 90 °C and an initial pH value of 6.3 showed that it reacts with Ankerite for a short period of time. The effect of Ankerite on borosilicate glass durability through magnesium-silicate precipitation has been investigated and confirmed in this study.
