Isolated posterior malleolus fracture – magnetic resonance imaging diagnosis
Authors: Duarte Márcio Luís , Brehme de Abreu Bruno Fernandes Barros , Lopes Daniel Tomaz , Almeida Prado José Luiz Masson de , Pereira da Silva Marcelo de Queiroz
Published: November 2022

Approximately 7% to 44% of ankle fractures involve the posterior tibial margin. These fractures tend to have a poorer prognosis than fractures without posterior involvement. Recognition of posterior malleolar fracture patterns is more important than fracture fragment size in decision making. Standard ankle radiographs are not effective for diagnosing isolated posterior malleolar fractures. There is consensus that the true size and geometry of the fragment, specifically its medial propagation, and intercalary fragments may be diagnosed only by computed tomography scanning. Magnetic resonance imaging may yield additional information about syndesmotic ligaments, tendons and osteochondral lesions, although it is used only exceptionally. There are controversies about the treatment of these fractures but authors agree that small fragments can be treated conservatively whereas larger fractures that involve more than 25% of articular surface should be fixed to avoid instability and degenerative changes. The authors report a case with a magnetic resonance imaging diagnosis of this fracture.

На основі дитопних порфіринів, структура яких дозволяє отримувати різноманітні гетерометалічні комплекси, отримано сполуки порфіринів з Nd(III), Yb(III) та Cu(II), Zn(II), Pd(II). Зазначені f-метали були обрані через те, що інфрачервона люмінесценція цих іонів металів може бути сенсибілізована порфіринами, а, з іншого боку, представлені іони d-металів мають різний вплив на порфіриновий хромофор. Фотосенсибілізована 4f-люмінесценція в ближній інфрачервоній області та молекулярна флуоресценція у видимій області гетероядерних 3d-4f комплексів надзвичайно чутливі до природи іонів d- та f-металів. Так, у випадку вільних порфіринових ядер і комплексів з Zn(II) характерна ефективна молекулярна флуоресценція (квантовий вихід 4–11 %). Крім того, для цих цих сполук характерні три типи випромінювання одночасно – це флуоресценція, фосфоресценція та 4f-люмінесценція і нами було встановлено, що ефективність всіх видів емісії та значення максимумів їх смуг не залежать від природи периферичних хелатних фрагментів. Флуоресценція комплексів купруму та паладію майже повністю погашена, але Pd(II)-порфірин виконує роль 4f-сенсибілізатора на відміну від Cu(II)-порфірину. Розглянуто вплив кисню на люмінесценцію комплексів і виявлено, що лише комплекси Pd-Nd чутливі до його присутності – деоксигенація призводить до 20 % підвищення ефективності 4f-люмінесценції.

Рослинні відходи – перспективний відновлюваний природний матеріал для екосорбентів. Біовугілля – стабільний вуглецьвмісний продукт, який синтезується в результаті піролізу (карбонізації) рослинної біомаси. Вивчена можливість отримання екосорбенту з багасси (рослинних відходів виробництва цукрової тростини). У процесі отриманні екосорбентів для поглинання комплексних сполук іонів важких металів використовували хіміко-біологічну модифікацію біовугілля. Сірковмісний біовугілля отримували хімічною модифікацією шляхом одностадійного піролізу сировини спільно з сірковмісними реагентами. Його специфічність зумовлена утворенням нерозчинних сульфідів важких металів на поверхні та в порах сорбенту. Мікробіологічна модифікація призводить до створення біосорбційного матеріалу для міцного зв'язування іонів важких металів. Іммобілізовані на поверхні біовугілля сульфатредукуючі бактерії здатні переводити сорбовані важкі метали в нерозчинні сульфідні форми. Проведено комплексне дослідження структурно-пористих та сорбційних властивостей вихідного та модифікованого біовугілля. Порівняльний аналіз адсорбційної здатності вихідного багаси, біовугілля з багаси, біовугілля, модифікованого сіркою, та біовугілля з іммобілізованими на його поверхні сульфатредукуючими бактеріями показав, що хімічно та біологічно модифіковане біовугілля з багаси цукрової тростини здатне міцно зв'язувати іони важких металів. Хімічно і біологічно модифіковане біовугілля з багаси цукрової тростини може використовуватися як ефективні екосорбенти для детоксикації важких металів у водних та ґрунтових середовищах.

З використанням методів квантово-хімічного моделювання досліджено вплив ненасичених двоосновних органічних кислот на термодинамічні характеристики реакції одноелектронного окиснення ацидоаквакомплексів Mn2+, які визначають базовий рівень енергоефективності процесу електрохімічного синтезу MnO2. Показано, що монодентатні аніонні форми малеїнової (НМ–) та фумарової (HF–) кислот не мають будь-яких переваг відносно аніонів монокарбонових кислот, зокрема, – ацетат-йонів. Навіть навпаки, утворення водневих зв’язків з внутрішньосферними молекулами води другою карбоксильною групою, яка не зв’язана з центральним атомом, суттєво погіршує ефективність впливу аніонів НМ– i HF– на стадію вилучення електрона з комплексів [Mn2+(L)(H2O)5]. Величина стандартного редокс-потенціалу E0(Mn2+/Mn3+) йонних систем з однозарядними аніонами малеїнової і фумарової кислот становить 1.05 В і 0.99 В відповідно, що значно перевищує E0(Mn2+/Mn3+) ацетатних комплексів (0.66 В), наразі рекомендованих до практичного використання. Присутність у внутрішній координаційній сфері ацидоаквакомплексів Mn2+ бідентатно зв’язаного двозарядного аніона малеїнової кислоти зменшує E0(Mn2+/Mn3+) до 0.32 В, а це вдвічі менше, ніж в ацетатному електроліті. Перспективність малеїнатних електролітів посилюється також здатністю ненасичених аніонів М2– каталізувати стадію диспропорціонування комплексів Mn3+.

Objetivou-se analisar as mediações pedagógicas realizadas na disciplina de língua portuguesa, no que tange a literatura dos anos finais do ensino fundamental com a finalidade de contextualizar o sujeito quilombola em Bela Vista-PI na pandemia de COVID-19. O levantamento de dados foi feito através da análise do conteúdo dos cadernos de atividades encaminhados pelas escolas aos alunos dos anos finais do ensino fundamental durante os meses de agosto e dezembro do ano de 2020. Para dar suporte à análise, contribuíram com o estudo a respeito da mediação as abordagens de Alves (2020), Antunes (2014) e Pino e Sigardo (2000). Referente à mediação e à contextualização no ensino de língua portuguesa, as produções de Soares (2002), Bernardo (2016); Daros (2021) colaboraram com pesquisa a respeito da educação na pandemia de COVID-19 e sobre a educação do sujeito quilombola. Foi possível constatar que, embora a contextualização da vida do sujeito quilombola, bem como de outras minorias, no ensino na disciplina de língua portuguesa pudesse contribuir para a inclusão, os professores não a empregaram como instrumento pedagógico.
Wallmapuwen – a busca pela autonomia mapuche na política chilena
Authors: Rosa Stefania Dalla
Published: November 2022

A história do povo Mapuche frente ao Estado chileno foi e continua sendo muito conturbada, a partir da anexação do território originário após a Guerra de Pacificação da Araucanía, em 1883. No decorrer de todo o século XX, surgiram movimentos pela retomada do território e por uma representatividade Mapuche na região da Araucanía, que se intensificaram nos anos 1990, no período de redemocratização.A partir da análise da “Declaración de Principios de Wallmapuwen”, o primeiro partido Mapuche, fundado em 2005 e legalizado em 2016, buscou-se compreender a percepção do Wallmapuwen a respeito da identidade étnica e nacional, nacionalismo e democracia, assim como os princípios políticos e ideológicos do partido, os agentes sociais pertencentes à “nação Mapuche”, planos de recuperação territorial e suas aspirações políticas a nível regional e nacional. Recorrendo ao conceito de identidade nacional e etnia de Anthony Smith como referencial teórico e analisando o documento a partir desses conceitos, foi demonstrado que não podemos caracterizar Wallmapuwen apenas como um partido étnico, uma vez que defende um pluralismo de agentes sociais mapuches e não mapuches. Busca um diálogo com o governo chileno em busca de descentralizar a política dando mais autonomia para as regiões e a recuperação territorial, focando na diminuição dos impactos ambientais. Conclui-se, portanto que Wallmapuwen se coloca como um partido democrático, autonomista, laico, pluralista e nacionalitário.

Aim: to estimate the effects of a group using digital technologies and physical activity on cognitive function and health variables in the elderly. Methods: intervention research with 29 elderly men (n=7) and women (n=22), all from the University of Cruz Alta community. The intervention consisted of a Program to use digital technologies and practice physical activity (walking). It had weekly meetings (total of 16 meetings) of approximately 90 minutes, first using digital technologies – computers and internet (approximately 60 minutes) and then walking (30 minutes). Cognitive function was measured by the Mini Mental State Examination. Sex, age, marital status, education, disease diagnosis, vision problems, medication, use of tobacco and alcohol and functional capacity were also collected through a questionnaire. The Body Mass Index was also checked. Participants were assessed before and after the program. The data were analyzed by paired Student’s t-test with a 5% probability. Results: it was evident that the proposed program improved cardiorespiratory fitness (519.14 pre-test - 583.86 post-test, p = 0.005) and cognitive ability (25.90 pre-test - 26.21 post-test, p> 0.001) of participants, in addition to influencing the cessation of tobacco use (20.7%). Conclusion: these results show the importance of programs aimed at the cognitive improvement of elderly people, and health variables, considering that these can and should be inserted in health care settings.
Disnarration and the performance of storytelling in Taylor Swift’s folklore and evermore
Authors: Harrison Chloe , Ringrow Helen
Published: November 2022

In a similar way to dramatic performances and plays, song lyrics establish a complex discourse structure whereby listeners are placed in a position to overhear ‘the pretence of a conversation constructed to convey the performer’s meaning’ (Nahajec 2019: 25; see also Short 1996: 169). In Swift’s songwriting, listeners are positioned not only to eavesdrop on the narratives presented, but are also invited to conceptualise and enact particular roles and scenarios in the discourse. This paper offers a stylistic analysis of songwriting and narrative structure across Swift’s oeuvre to identify how disnarration strategies are used to build stories in her two sister albums written and produced during the Covid-19 pandemic, folklore (2020) and evermore (2020). Specifically, this study examines how disnarration characterises the albums’ narrators, establishes narrator-narratee relationships and invites listeners to adopt a participatory role in the meaning-making process. Through close analysis of four songs across the two albums, this paper builds on developing studies of the stylistics of songwriting (see West 2019), and argues that disnarration strategies foreground particular themes within the discourse, such as nostalgia, wistfulness and regret, and contribute to the fictionalisation and self-aware storytelling characteristic of these albums’ storyworlds.

Published: November 2022

The Indian Himalayan sector is well known to support the diversified bryophyte species and communities due to varied phytoclimatical conditions met within different dissected topographical zones. Many potential wilderness areas are still waiting to be explored in terms of their exuberant bryodiversity. During a bryoexploratory survey of an unexplored high-altitude area in the Garhwal Himalayan region, we came across an interesting rheophytic moss Bryocrumia L. E. Anderson. The genus Bryocrumia is represented in India by two species, viz. B. vivicolor (Broth. et Dixon) W. R. Buck and B. malabarica Manju, Prajitha, Prakashkumar et W. Z. Ma. Both of these pleurocarpous species are known to be confined in the southern part of the country. From the Indian Himalayan sector, this moss genus has never been documented earlier. Recently, B. vivicolor has been reported for the first time from the Tungnath area (2,100–3,000 m above sea level) in the Garhwal region of Uttarakhand state as a new addition to the Western Himalayan moss flora, indicating its new distributional range. This hypnaceous moss was found colonising the slopy, wet, submerged rock surfaces along small streams and seepages in mixed oak forests on way to Tungnath. The key characteristics include its rheophilic habit, stem lacking central strand, variable leaf forms, indistinct double costa and round to obtuse leaf apex with prorate tip cells. The present paper provides taxonomic details of this rare moss, representing its wide geographical distribution in India.

EVOLUTION OF PERICARP SURFACE STRUCTURE IN NEPETA S. S. (LAMIACEAE) AS INFERRED FROM ANALYSIS OF ITS DATA
Authors: Mehregan I. , Ghanbarpour K. , Shamsabad M. M.
Published: November 2022

Nutlet pericarp structure is important in the taxonomy of Lamiaceae (Labiatae) at different taxonomic levels. Within the family it has also been found that variation in pericarp structure is strongly correlated with the phylogenic results obtained from molecular DNA analyses. The genus Nepeta L., with more than 200 species mainly centred in SW Asia, is one of the taxonomically most complex genera within the family. Traditional taxonomic treatments of Nepeta are mainly based on gross morphology. As in other groups of Lamiaceae, pericarp structure provides some of the diagnostic characters in this genus. In order to investigate patterns of pericarp evolution within Nepeta, we used scanning electron microscopy to examine nutlet surfaces and pericarp cross sections and explored variation of these characters against a molecular phylogeny based on ITS sequences. Based on this phylogenetic analysis, Nepeta in its present circumscription is not monophyletic. Evolutionary trends in structure of nutlet pericarps are apparent although they require confirmation with more robust phylogenies. In particular, nutlets with tuberculate/thorny-like pericarp may have evolved once within this genus, in the common ancestor of five of the six subclades identified within Nepeta, and have been lost independently several times. We also show that evolution of tubercules in Nepeta is not related to plant life span. Our results also indicate that more genetic markers (both plastid and nuclear) are necessary to reconstruct a reliable and robust organismal phylogeny.
Morphology aware data augmentation with neural language models for online hybrid ASR
Authors: Tarján Balázs , Fegyó Tibor , Mihajlik Péter
Published: November 2022

Recognition of Hungarian conversational telephone speech is challenging due to the informal style and morphological richness of the language. Neural Network Language Models (NNLMs) can provide remedy for the high perplexity of the task; however, their high complexity makes them very difficult to apply in the first (single) pass of an online system. Recent studies showed that a considerable part of the knowledge of NNLMs can be transferred to traditional n-grams by using neural text generation based data augmentation. Data augmentation with NNLMs works well for isolating languages; however, we show that it causes a vocabulary explosion in a morphologically rich language. Therefore, we propose a new, morphology aware neural text augmentation method, where we retokenize the generated text into statistically derived subwords. We compare the performance of word-based and subword-based data augmentation techniques with recurrent and Transformer language models and show that subword-based methods can significantly improve the Word Error Rate (WER) while greatly reducing vocabulary size and memory requirements. Combining subword-based modeling and neural language model-based data augmentation, we were able to achieve 11% relative WER reduction and preserve real-time operation of our conversational telephone speech recognition system. Finally, we also demonstrate that subword-based neural text augmentation outperforms the word-based approach not only in terms of overall WER but also in recognition of Out-of-Vocabulary (OOV) words.
A szemnyomás változásának hatása a szaruhártya és a szem törőerejére a Liou–Brennan-modellszem alapján

Published: November 2022

Bevezetés: Klinikai tapasztalat, hogy jelentősen magasabb
szemnyomás esetén a szemüvegrendelés pontatlan lehet, ezért célszerű azt a
szemnyomás rendezése után elvégezni. Célkitűzés: A
szemnyomásértékek hatásának vizsgálata a szaruhártya és a szem törőerejére, a
Liou–Brennan-modellszem geometriai tulajdonságain alapuló numerikus modell
felhasználásával. Módszerek: A Liou–Brennan-modellszem
corneaparamétereinek felhasználásával elkészítettünk egy paraméteres geometriai
modellt, majd a modellszem végeselemes modelljét az Ansys program használatával.
A szaruhártya anyagának viselkedését Wollensak alapján trilineáris
anyagmodellel, a peremfeltételeket Pandolfit követve írtuk le. A
szemnyomásváltozás hatását vizsgáltuk a szaruhártya optikai szempontból lényeges
geometriai adataira (az elülső és hátsó corneagörbület az optikai centrumban,
valamint az elülső és hátsó corneafelszín tengelyirányú eltolódása az optikai
centrumban). A kapott geometriai jellemzők alapján a paraxiális sugárkövetés
módszerével számítottuk a szaruhártya és a szem optikai tulajdonságaiban
bekövetkező változásokat. Eredmények: A növekvő
szemnyomásterhelés hatására az elülső és hátulsó corneafelszínek középponti
görbületi sugarai csökkentek, az elülső és hátsó szaruhártyafelszínek
középpontjai előretolódtak, a szaruhártya vékonyodott. A szaruhártya pontjainak
tengelyirányú eltolódásai valamennyi szemnyomásterhelés esetén a hátulsó felszín
középpontjában vették fel maximális értéküket. A szaruhártya törőereje a
szemnyomás fokozódásával csökkent, míg a szem teljes törőereje növekedett.
Következtetés: A Liou–Brennan-modellszem geometriai
tulajdonságain alapuló végeselemes numerikus modell felhasználásával igazoltuk,
hogy a 10 és 30 Hgmm közötti szemnyomásváltozás 0,31–0,86 mm csökkenést okoz a
szaruhártya görbületi sugarában, 1,5–4,8 D növekedést a keratometriás
értékekben, valamint 1,2–3,9 D növekedést a szem törőerejében. A szaruhártya
törőerejében 0,14–0,69 D csökkenés tapasztalható a vizsgált
szemnyomástartományban. Orv Hetil. 2022; 163(47): 1872–1879.

Air conditioning (AC) merupakan salah satu faktor penunjang kenyamanan penumpang transportasi kereta api. Sistem pengkondisi udara berkaitan erat dengan besaran termal berupa temperatur dan kelembapan yang memiliki standar khusus untuk tingkat kenyamanan penumpang. Nilai temperatur dan kelembapan diketahui dengan pengukuran yang menghasilkan nilai akurat atau terkalibrasi mengacu pada Peraturan Menteri 175 tahun 2015 yang dirujuk dari standar UIC 533 al. Pada penelitian sebelumnya, alat ukur temperatur dan kelembapan kurang efisien karena pengambilan data hanya berasal dari satu titik tertentu, sehingga peneliti merancang bangun alat ukur yang mengukur nilai temperatur dan kelembapan pada delapan titik pengukuran secara bersamaan menggunakan transduser DHT22. Data yang ditampilkan alat ukur adalah data hasil pengujian pada Kereta Rel Diesel Elektrik (KRDE) yaitu nilai temperatur dan kelembapan. Data tersebut dapat diakses dari hasil penyimpanan modul kartu memori. Alat ukur ini digunakan secara nirkabel atau wireless. Hasil penelitian ini menunjukan nilai error pada temperatur sebesar 6 % dan pada kelembapan sebesar 35 %. Error yang terdapat pada SMD22 dapat diterima.The air conditioning system (AC) is one of the factors supporting passenger comfort in rail transportation. The air conditioning system is closely related to thermal quantities in the form of temperature and humidity which have special standards for the level of passenger comfort. Temperature and humidity values are known by measuring instruments that produce accurate or calibrated values referring to PM 175 of 2015 which is referenced from the UIC 553 standard. In previous studies, temperature and humidity measuring instruments were less efficient because the data taken only came from one particular point, so the researchers designed a measuring instrument that measured the temperature and humidity values at eight measurement points simultaneously using a DHT22 transducer. Data displayed by measuring instrument is result testing on the Electric Diesel Rail Train room, namely temperature and humidity values. And the data can be accessed from the results of storage on the memory card module. The goals of this research are the characteristics of measuring instruments for measuring temperature and humidity of 8 measurement points in realtime and the measurement data stored on a memory card. This measuring instrument is used wirelessly. The results of this study are temperature and humidity data with error values at temperature of 6% and humidity of 35%. Errors contained in SMD22 are acceptable.

Published: November 2022

We discuss in this paper the robust equivariant nonparametric regression estimators for ergodic data with the k Nearst Neighbour (kNN) method. We consider a new robust regression estimator when the scale parameter is unknown. The principal aim is to prove the almost complete convergence (with rate) for the proposed estimator. Furthermore, a comparison study based on simulated data is also provided to illustrate the finite sample performances and the usefulness of the kNN approach and to prove the highly sensitive of the kNN approach to the presence of even a small proportion of outliers in the data.
“We Need Knowledge for Life, a University Free of Colonialism”
Authors: Cariño Trujillo Carmen , Montelongo González Alejandro
Published: November 2022

This document reflects on the decolo­nization of knowledge and universities through reflection on the role of confer­ences as spaces of decolonization. The reflection emphasizes the recognition of the place of enunciation of the writer and from there engages in sentipensar about the importance and urgency of working for decolonization beyond conferences and beyond universities. The analysis is based on the idea that decolonization is more than a discourse or a metaphor; it is a project for life with both feet on the ground. Colonialism is today a daily and constant reality that racialized people are faced with more violence, but at the same time from these places of resis­tance, important reflections and actions towards decolonization are emerging. This text also analyzes the role of Indigenous scholars and the criticism of universities as a hegemonic place of the production of knowledge.

Published: November 2022

Abstract Asparagus umbellatus is one of the most popular cut foliage plants that widely used in decorations and bouquets. However, there was a lack of information concerning Asparagus postharvest handling. Therefore, in this study, two growth regulators gibberellic acid (GA) and salicylic acid (SA) on concentrations of 0, 100, 200, and 400 μM were applied in two stages viz., pre and postharvest, separately and in combination. Experimental traits including; chlorophyll content, electrolyte leakage, solution uptake, microbial population, relative water content (%), malondialdehyde content, catalase, superoxide dismutase, and peroxidase activity along with plant vase life were evaluated. The results showed that the application of GA and SA lead to significantly extension of the vase life compared to the control. Vase life difference between control (9.34 days) and the superior treatment i.e. GA200+SA200 (14.07 days) was more than 50%. Also, the pre-harvest foliar application of GA and SA increased the vase life slightly compared to the application in vase solution. The extended vase life in the per-harvest experiment was obtained using SA100+GA100 and SA200+GA200 treatments.

Authors: Gerbaldo Tiziana Bezerra , Antunes José Leopoldo Ferreira
Published: November 2022

Resumo A preocupação com o consumo prejudicial de álcool está na interseção da pandemia com a saúde mental. Mudanças nos padrões de consumo durante a crise sanitária têm sido documentadas no Brasil e internacionalmente. Este estudo avaliou o impacto da pandemia nos procedimentos a usuários de álcool no Brasil, por meio dos registros dos Centros de Atenção Psicossocial (CAPS). Selecionaram-se dados de janeiro de 2019 a dezembro de 2020, com discriminação por macrorregião geográfica, sexo, idade e raça/cor. Realizou-se análise descritiva, cálculo da variação percentual e distribuição em séries temporais. A análise comparativa apontou redução nos procedimentos no início da pandemia (-52,4%), com diferenças entre sexo e faixa etária. Observou-se diferenças entre macrorregiões, com pior resultado no Norte do país (-70,1%). O segundo semestre de 2020 apresentou retomada nos procedimentos, porém em quantidade aquém do realizado no ano anterior (-41,7%). Houve aprofundamento das desigualdades já existentes, especialmente com a queda mais elevada nas macrorregiões mais pobres, com maior fragilidade na rede de saúde mental. Dada a magnitude do álcool como problema de saúde pública e o papel central dos CAPS, ressalta-se a necessidade de instituir políticas e programas de saúde visando minimizar o impacto da pandemia na redução da assistência psicossocial.

Utilisation of wheat straw for concrete insulation brick
Authors: Yin JiMing
Published: November 2022

The use of wastes as part of insulation building materials has become a new requirement of green building. This study aimed to investigate the feasibility of using wheat straw as a filler for making thermal insulation bricks to reduce energy loss in buildings. Wheat straw, expanded perlite and asphalt were used to produce straw insulation blocks (SIBs), and the mix ratio of the materials used was determined using the orthogonal method. A reasonable mixing ratio is as follows: wheat straw content (weight ratio) is 23.8%, expanded perlite content 19.8% and asphalt content 56.4%. SIBs were filled into hollow concrete bricks to prepare straw insulation block core-filled concrete bricks (SIBCCBs). The density, compressive strength and thermal conductivity of SIBCCB were measured. The results indicate that the SIBCCB is lightweight, has low carbon dioxide emissions, good thermal insulation performance and compression resistance capacity, and is an ideal insulation block for load-bearing lightweight and non-load-bearing walls.

“Such a Good Night”: Analyses of Korean-English code-switching and music video comments of ASTRO’S songs
Authors: Berliana Alya Ditha , Anjarningsih Harwintha Yuhria
Published: November 2022

To attract global multilingual audiences, English lyrics had been included in K-Pop songs for decades as a strategy (Lauren, 2018; Sea, 2018). This paper analyzed the English usage of “All Night”, “Blue Flame”, and “Knock” by ASTRO, a third-generation K-Pop group from a non-mainstream agency to examine code-switching and the global recognition of K-Pop songs. All songs were examined by using code-switching theories from Poplack (1980) and Bullock and Toribio (2009) and other theories on function analysis by Lawrence (2010) and Lee (2004) and comment analysis by Fernandez-Martinez et al. (2014) and Kwon (2019). The findings revealed that the majority of code switches in “All Night” and “Blue Flame” were inter-sentential, yet “All Night” and “Knock” were more similar in utilizing English by having a new function (i.e., emphasizing a dialog from one’s perspective), an important addition to Lee’s (2004) functions. Furthermore, from the usage and function analysis and the comment analysis, the audience responses seemed to be influenced by the singers’ mispronunciations and the non-existence of a new function that failed to create uniqueness in English usage in “Blue Flame,” which may have led to the song’s failure to win awards. In conclusion, the research suggested that, in the near-absence of promotional support from the agency, the interplay among the number of switches, accurate pronunciations, and a new English-switching function seemed to play an important role in making “All Night” and “Knock” popular among multilingual audiences.
The effect of input modality on German as a FL learners’ provision of recasts in oral peer interactions
Authors: Kirchhoff Natalie , Dávila-Romero Raúl
Published: November 2022

Interaction between learners is proven to be beneficial for second and foreign language acquisition. This article reports on a quasi-experimental study conducted in a German as a foreign language (GFL) classroom in a university in Spain. The study explored the effect of input modality on the provision of recasts in oral peer interactions. Two intact classes of GFL, one with 12 and the other with 16 learners, participated in six oral interaction tasks. The researchers divided the two classes into two groups: one group was only exposed to aural and visual input, while the other also received written input. Audio recordings and full written transcripts of learners’ oral peer interactions in the two groups were made and the frequency and nature of recasts were analysed quantitatively in order to examine the effect of input modality on the production of this corrective feedback type. Results suggested that input modality impacted the way learners interacted with each other. Findings showed that learners who were not provided with written input provided significantly more recasts to each other. Results also revealed that the nature of the recasts (i.e., form-, lexical- and pronunciation-focused recasts) that learners produced was input modality dependent. Since the provision of recasts is beneficial for second and foreign language acquisition, the results indicate that teachers and task designers should consider input modality as a relevant task design variable.
