Hydrological-hydrodynamic simulation and analysis of the possible influence of the wind in the extraordinary flood of 1941 in Porto Alegre
Authors: Possa Thais Magalhães , Collischonn Walter , Jardim Pedro Frediani , Fan Fernando Mainardi
Published: November 2022

ABSTRACT The great flood of 1941 remains the most impactful and traumatic flood event in the history of Porto Alegre. This event was caused by a combination of heavy rainfall in the basin in the days prior to the peak of the flood, and the wind that occurred during the flood. However, the influence of wind on the maximum flood level, although frequently mentioned, is not well known. This is largely because there are no systematic data for wind speed measuring and direction in 1941. Therefore, the present work aims to estimate the discharge and the maximum flood level in the city of Porto Alegre and in other relevant points of the basin. using hydrological-hydrodynamic modeling and, from there, analyze the possible role of the wind during the flood, through the simulation of hypothetical wind scenarios. The results showed that the discharges and levels were represented reasonably well with the MGB model at several locations in the basin. In relation to the 1941 event and the scenarios created, the contribution of the wind to the peak of the flood was of the order of a few to tens of centimeters, showing its potential role despite the limitations of the model.

Published: November 2022

Abstract The bromeliads are desirable vase plants because of the flowering bract and the usually large, bold, colored and exotic format of the leaves that forms a cistern. The main function of epiphytic bromeliads roots is the fixation on the substrate, while water and nutrients uptake are performed mainly by leaves. However, recent studies have shown that the roots of epiphytic bromeliads can also help in the absorption of water and nutrients, contributing to plant growth and development. The present study aimed to evaluate the importance of the root system in the mineral nutrition of an epiphytic ornamental bromeliad silver vase bromeliad (Aechmea fasciata) that occurs in Brazil. 80 plants were cultivated for 240 days in plastic pots (900 mL) containing composted pine bark and were subjected to 5 treatments with 50 mL of 0% (control), 25%, 50%, 75% and 100% Hoagland & Arnon (HA) nutrient solution, applied twice a week only onto the substrate. Biometric and biomass variables of root and shoots, as well as macro- and micronutrients content in silver vase bromeliad leaves were evaluated. Results showed that all biometric and biomass parameters increased with the application of increasing HA solution concentrations, while the nutritional content in leaves showed different responses, with increase in nitrogen and potassium, decrease in calcium, phosphorus, magnesium, manganese, copper, sulfur, iron and zinc. We conclude that silver vase bromeliad grows better when fertilized with 75% or 100% HA solution on the substrate. We emphasize that the roots of the epiphytic silver vase bromeliad are functional and plays important roles in its nutrition and growth.

Published: November 2022

Abstract The key role of auxins as integrators of environmental signals has become well-known in recent years, and emerging evidence indicates that auxin biosynthesis is an essential component of the overall mechanisms of plant tolerance to stress. However, although the knowledge of the involvement auxins in the responses related to the generation of roots and accumulation of biomass, studies in ornamental species concerning the commercial propagation in plug cell trays are scarce. Thus, the aim of this work was to evaluate the accumulation of pre-transplant biomass in Impatiens walleriana plants growing in two propagation systems (soilless medium-based plug cell trays and a floating system) with trays of different cell sizes and sprayed either with a single dose of the auxin indole acetic acid (IAA) or with two inhibitors of endogenous auxins, N-1-naphthylphthalamic acid (NPA) and 2,3,5-triiodobenzoic acid (TIBA). Our results demonstrate that plants from both floating system and those sprayed with IAA present both the highest leaf area and fresh and dry weight at the end of the experiment. Conversely, as a negative control, the use of NPA and TIBA as antagonists of the synthesis and translocation of auxins caused an opposite effect in such variables as compared to control plants. However, before making commercial recommendations, it would be necessary to evaluate the potential post-transplant effects of these treatments on the generation of I. walleriana yield.
Ornamental plant breeding: entering a new era?
Authors: Huylenbroeck Johan Van , Bhattarai Krishna
Published: November 2022

Abstract During the last century, plant breeding of crops and ornamentals has become an important business. Mendel’s principles of inheritance of traits laid the foundation of today’s modern genetics. Although intra- and interspecific cross breeding, chromosome doubling and mutation breeding still form the cornerstone of ornamental plant breeding, the speed of plant breeding has significantly increased since Mendel’s time. New genomic tools now offer possibilities for advanced precision breeding and selection towards more difficult to assess or quantitative traits. Today’s ornamental plant breeding is a complicated exercise, characterized by new and rapidly-changing challenges. Partnerships between industry and research will be essential to implement available technologies in minor crops.

Published: November 2022

Objetivou-se analisar a vivência de cuidadores de crianças com a síndrome congênita do Zika, no contexto familiar e social. Trata-se de um estudo qualitativo com dez cuidadoras de crianças com síndrome congênita do Zika vírus, em um serviço pernambucano de referência à criança com deficiência, realizado no período de novembro de 2018 a março de 2019. Os dados foram coletados por meio de entrevista semiestruturada e interpretados pela análise temática. As cuidadoras, principalmente mães, dedicam-se integralmente aos cuidados do filho com a síndrome; enfrentam lutas diárias em busca de melhores condições de vida; abdicam de sonhos, emprego e estudos; e enfrentam dificuldades financeiras e no cuidado a outros filhos. Assim, são necessárias ações de saúde focadas na singularidade das famílias para viabilizar a oferta e/ou fortalecimento de redes de apoio e ampliar as possibilidades para melhores condições de vida das mulheres e de seus filhos com a síndrome.

Domestic Workers: Postcolonial Inheritance and International Relations
Authors: Pozo Karen Johanna
Published: November 2022

Abstract The discipline of International Relations (IR) in Latin American is still dominated by positivist and Westernized research. This creates challenges for international studies such as how to visualise the subjects or ‘sujetas’ who participate in national and international politics but are ignored in this field, and how to value the current postcolonial research, which offers critical perspectives that equilibrate the epistemic balance and help build adequate tools to understand different regional phenomena. By analysing a case study of the Association of Women Domestic Employees of Paraguay, this article clarifies how a postcolonial approach enriches the field of IR. This study argues that postcolonialism contributes to this field by making visible cognitive subjects and ‘sujetas’, who offer an alternative knowledge construction to rethink international relations with a meta-theoretical extension, visible. Postcolonialism is the theoretical basis of this qualitative research. Data was collected through semi-structured interviews and participant observations. This article suggests and concludes that women domestic workers as ‘political subjects’ enrich international relations by offering critical views to the research carried out in the subfields of foreign policy analysis, international political economy, and regionalism.
Avaliação do potencial de coagulante recuperado de lodo de estação de tratamento de água para uso em águas de baixa e elevada turbidez
Authors: Pedretti Angela , Medeiros Raphael Corrêa
Published: November 2022

RESUMO Este estudo propôs-se a verificar a viabilidade de recuperação de coagulante utilizado na estação de tratamento de água Palmitinho (RS) pelo emprego do processo de extração por via ácida de lodo, observando a possível aplicação do recuperado para o tratamento de água bruta, com duas características distintas: baixa e elevada turbidez. A regeneração de coagulante por via ácida apresentou-se como alternativa viável, propiciando concentração de 683,31 mg.L−1 de sulfato de alumínio ao recuperado. Nos ensaios em águas de baixa e elevada turbidez, o coagulante recuperado, quando testado em águas de elevadas turbidez e cor, mostrou-se com faixa de aplicabilidade superior ao coagulante comercial, com remoção ≥ 90% de turbidez em praticamente todas as faixas de pH testadas, bem como eficiência na remoção de cor aparente e verdadeira, porém houve limitação do emprego do coagulante recuperado ao transferir cor à água a ser tratada, quando de baixa turbidez, para a qual o coagulante comercial se apresentou mais eficiente. O emprego do coagulante recuperado não atendeu aos requisitos para a concentração de impureza permissível por produto, levando-se em consideração a concentração de impureza padronizada na água calculada para os elementos manganês e cádmio proposta pela norma brasileira 15784. Portanto, não se apresentou viável em tratamento de águas naturais. Além disso, mesmo tendo proporcionado redução de aproximadamente 45% no volume final de lodo, o resíduo insolúvel obtido apresentou características físico-químicas que podem dificultar sua disposição final.
Inorganic solar filters incorporated to carnauba wax and incidence of citrus black spot on tangerine
Authors: Nascimento Fernanda Varela , Valdebenito-Sanhueza Rosa Maria , Bender Renar João
Published: November 2022

Abstract The objective of this work was to evaluate the effect of zinc (ZnO) and titanium (TiO2) oxides, added to carnauba wax emulsions, on the incidence of citrus black spot (CBS) caused by Phyllosticta citricarpa and, consequently, on tangerine quality. Wax emulsions blended with ZnO or TiO2 were sprayed up to concentrations of 8% on late-season tangerine cultivars. Three experiments were carried out in a randomized complete four-block design, with two control treatments – one with the application of only the carnauba wax emulsion and the other without the application of the emulsion. The spraying of ZnO and TiO2 reduced the incidence of the disease on the harvested fruit; however, the increase in the concentrations of the oxides did not improve CBS control. Two consecutive applications of the oxides reduced the photosynthetic activity of the plants, negatively affecting yield, and caused damage to fruit peel. Tangerines infected artificially with 105 conidia mL-1 of P. citricarpa, before or after the sprayings of the photoprotective films, showed a reduced CBS incidence. The treatments with the application of only carnauba wax do not differ from those with films combined with ZnO and TiO2 regarding the control of CBS incidence. The addition of inorganic oxides to the carnauba films limits the photosynthetic activity and reduces the yield of the plants, besides damaging the visual quality of the tangerines.
Bud-break promoters for the improvement of the budburst of pecan cultivars

Published: November 2022

Abstract The objective of this work was to evaluate the effect of different bud-breaking substances on the budburst of the Barton, Desirable, and Jackson pecan (Carya illinoinensis) cultivars. The experimental design was a randomized complete block with four replicates. The treatments consisted of spraying different rates of commercial bud-break promoters on the trees of these cultivars, in order to induce budburst. The budburst percentage of axillary buds and the budburst heterogeneity index (BHI) were evaluated. Regardless of the used rate, the application of the hydrogen cyanamide product improved the budburst of the tested cultivars and reduced the BHI. In addition, water soluble N + Ca at 6% and water soluble N + organic C soluble in water at 7% significantly improve the budburst and reduce the BHI of the evaluated cultivars, being, therefore, potential alternatives to replace hydrogen cyanamide.
As práticas pedagógicas e a autonomia de professores no contexto de ensino bilíngue de elite
Authors: Mayer Luana Francine , Koerner Rosana Mara
Published: November 2022

Resumo Neste artigo, sugerem-se algumas respostas sobre como a autonomia de professores de um contexto bilíngue de elite se faz perceber em suas vozes, através de análises do que dizem a respeito de suas práticas pedagógicas. A problemática que deu origem à pesquisa recaiu sobre as formações superiores variadas dos professores que não eram formados para trabalhar com níveis da educação infantil e séries iniciais; em alguns casos, tampouco eram formados em licenciatura. Esse “espaço” entre formação inicial e práticas pedagógicas lançou luz sobre questões que concernem à autonomia docente. O enfoque metodológico foi preconizado pela pesquisa qualitativa, valendo-se de um questionário escrito e de um grupo de discussão como instrumentos para geração dos dados. As reflexões foram embasadas nos seguintes autores: García (2009), Benson (1997), Benson e Huang (2008), Cunha (2007), Pesce (2012), Tardif (2002) e Megale (2020). Entendemos que, apesar de os professores não reconhecerem a autonomia em suas práticas, nem usarem essa palavra em suas falas, é por meio das escolhas que fazem para mobilizar o processo de ensinar e aprender que exercem o seu protagonismo e se empoderam no exercício da profissão. Conclui-se que o que evidencia sua autonomia parecem ser as decisões que tomam para adequarem suas práticas ao que a gestão espera, ao que os manuais de orientação indicam e ao que o livro do professor prevê, enquanto buscam uma prática que se mostre efetiva, mesmo que à revelia do controle imposto pela instituição.
Uma análise bibliométrica da recepção de Pierre Bourdieu na ciência política
Authors: Codato Adriano , Bittencourt Maiane , Perich Rafael , Silva Rodrigo
Published: November 2022

Resumo Pierre Bourdieu é o autor com a reputação mais bem estabelecida nas ciências sociais, em especial na Sociologia. Mas qual é a recepção de Bourdieu na ciência política? Se tomamos as citações aos seus livros nos periódicos mais importantes da área ela é inexistente. Por outro lado, há inúmeras pesquisas na França, no Brasil, na Argentina, no Chile, etc., sobre o campo do poder inspiradas por sua Sociologia da vida política. Este artigo investiga a presença e a influência do autor na ciência política publicada fora dos periódicos de maior impacto na disciplina. Partindo de uma base ampla de 25.475 documentos indexados na base Scopus que mencionam Pierre Bourdieu nas referências bibliográficas, analisamos 355 artigos que utilizaram seus conceitos-chave conectados à política, tais como campo político, Estado e poder simbólico. Verificamos que mesmo quando há citações aos escritos de Bourdieu, não são os trabalhos vinculados à sua sociologia da política que são referidos. Um estudo detalhado do contexto das citações para os vinte artigos mais citados desses 355 documentos mostrou que as referências a Bourdieu eram majoritariamente positivas e que havia mais menções de reconhecimento baseadas na autoridade do autor do que de corroboração com base em sua teoria. A influência das ideias de Bourdieu sobre os trabalhos analisados foi superficial em 17 dos 20 casos.

Resumo O trabalho discute ações com mini-histórias no cotidiano pedagógico sob a perspectiva de situações empíricas e narrativas de professores da Educação Infantil. Trata-se de investigar, a partir da análise de algumas experiências propostas por meio de um curso de extensão, de que forma é possível sustentar um processo formativo mediado por mini-histórias. O texto relata algumas experiências desenvolvidas entre 2017 a 2020 voltadas para práticas com mini-histórias na Educação Infantil. Discute, por meio da pesquisa-formação, o campo sensível do agir pedagógico, para contextualizar as práticas de mini-histórias na criação de registros éticos, estéticos e formativos. As mini-histórias se configuram como formas de fazer, ver, ser e narrar o cotidiano infantil, além de servir à documentação pedagógica, partindo da experiência sensível de aprender com as crianças. A construção de relações pedagógicas por meio de mini-histórias, a partir das referências e contradições em tempos de pandemia, fez emergir o desenvolvimento humano com valores e experiências próprias da cultura da infância. Os resultados da avaliação conjunta das propostas realçam o desconhecimento dessa forma de comunicação na Educação Infantil, conjugando o inédito viável.
First report of myiasis caused by Cochliomyia hominivorax in free-ranging giant otter (Pteronura brasiliensis)

Published: November 2022

Abstract Giant otters are territorial semi-aquatic mammals. It is common to find several individuals exhibiting wounds and scars due to intraspecific conflicts. Myiasis is a parasitic infestation on living tissues of vertebrates caused by dipterous larvae, that usually develops in freshly open wounds and can seriously threaten the host’s health. Ectoparasites seem to be rare among giant otters and myiasis had not been recorded in this species until now. Here, is presented one record of myiasis in a free-ranging giant otter found dead in the Pantanal, Brazil. An ulcerative lesion was found in the frontoparietal region, from which 22 larvae were recovered and identified as Cochliomyia hominivorax. The low occurrence of ectoparasites in giant otters might reflect their semi-aquatic habits and their grooming behavior, which makes it difficult for parasites to remain on the skin. The injured otter probably got the larvae after an intraspecific fight. Agonistic encounters between groups of giant otters have been reported before and these fights can result in serious wounds or even death. It was hypothesized that the myiasis caused by C. hominivorax deteriorated the health of the infested giant otter, which prevented recovery and accelerated its death.

Published: November 2022

Ovarian cancer manifests with early metastases and has an adverse outcome, impacting the health of women globally. Currently, this malignancy is often treated with cytoreductive surgery and platinum-based chemotherapy. This treatment option has a limited success rate due to tumor recurrence and chemoresistance. Consequently, the fundamental objective of ovarian cancer treatment is the development of novel treatment approaches. As a new robust tool, the CRISPR/Cas9 gene-editing system has shown immense promise in elucidating the molecular basis of all the facets of ovarian cancer. Due to the precise gene editing capabilities of CRISPR-Cas9, researchers have been able to conduct a more comprehensive investigation of the genesis of ovarian cancer. This gained knowledge can be translated into the development of novel diagnostic approaches and newer therapeutic targets for this dreadful malignancy. There is encouraging preclinical evidence that suggests that CRISPR/Cas9 is a powerful versatile tool for selectively targeting cancer cells and inhibiting tumor growth, establishing new signaling pathways involved in carcinogenesis, and verifying biomolecules as druggable targets. In this review, we analyzed the current research and progress made using CRISPR/Cas9-based engineering strategies in the diagnosis and treatment, as well as the challenges in bringing this method to clinics. This comprehensive analysis will lay the basis for subsequent research in the future for the treatment of ovarian cancer.
THE ROLE OF GIVING BACK IN THE PERSISTENCE OF WOMEN OF COLOR GRADUATE STUDENTS IN ENGINEERING AND COMPUTER SCIENCE
Authors: Jaumot-Pascual Nuria , Ong Maria , Silva Christina B.
Published: November 2022

This article examines the role of giving back in the persistence of women of color (WOC) students in engineering
and computer science graduate education. Using the theoretical frame of community cultural wealth (CCW), which facilitated exploring our topic from a strengths-based perspective, we analyzed 16 interviews and four extant texts from two recent projects. This study's research question is: How does engaging in giving-back activities support the persistence of women of color in engineering and computing
graduate education? We identified three giving-back activities that motivated WOC to persist: serving as a
role model, mentoring others, and creating counterspaces. Activities connect to multiple types of CCW. We
also recommend that institutions of higher education interested in retaining WOC in their engineering and
computer science graduate programs should integrate giving-back activities into their curriculum offerings.
Structural, electrical and thermistor behavior of BiFeO3–PbZrO3 for energy-storage devices
Authors: Mallick Priyambada , Biswal Susanta Kumar , Satpathy Santosh Kumar , Behera Banarji
Published: November 2022

The solid-state reaction technique is used to prepare samples of 0.3BiFeO3–0.7PbZrO3 and 0.5BiFeO3–0.5PbZrO3. Structural parameters, including percent crystallinity, dislocation density, microstrain and average size of crystallites, are calculated using X-ray diffraction data at room temperature. The scanning electron microscopy micrographs reveal the spherical, densely packed nature of the samples with low porosity. The dielectric constant and dielectric loss increase with the rising content of bismuth ferrite (BiFeO3) in the materials. The performance of the materials as a negative-temperature-coefficient (NTC) thermistor in the temperature range 300–450°C is discussed. The values of the thermistor constant (i.e. in the range 3911–6247 K) and the range of the sensitivity index (−1 to −9%) confirm the potential use of the samples as NTC thermistors. The frequency-dependent alternating current (AC) conductivity satisfies the universal Jonscher power law. The high density of states is determined from the frequency- and temperature-dependent AC conductivity of the materials.
Self-cleaning coating for exterior walls of concrete buildings

Published: November 2022

Due to the advantages of beautiful appearance, exterior wall real stone paint with properties of low cost and good weather resistance has been widely applied on concrete buildings for aesthetics and protection. However, the hydrophilicity of exterior wall real stone paint makes it susceptible to pollution by dust, acid rain and so on. Superhydrophobic coatings with excellent self-cleaning properties may effectively alleviate these problems, but the fabrication of real stone paint coatings with superhydrophobicity has not been reported yet. Here, the authors developed a superhydrophobic exterior real stone paint (SEP) coating with a water contact angle of 154 ± 3° and a rolling angle of 13 ± 2° through a simple and highly efficient physical blending method using an emulsion, natural sand, low-surface-energy reagents and nano-silicon dioxide (nano-SiO2). The SEP coating possessed excellent self-cleaning properties for pollutants, including soil, dust and rust water, and had good anticorrosion capability and outdoor time stability. The SEP coating also showed better solar reflectance characteristics than the normal exterior real stone paint coating, which may contribute to lowering of temperatures in buildings during hot weather and saving energy. Besides, a colorful SEP coating for decorative requirements and a large-area SEP coating for practical application could be effectively fabricated, which are expected to have promising application prospects.
From War into the Future: Historical Legacies and Questions for Postwar Reconstruction in Ukraine
Authors: Dyak Sofia
Published: November 2022

Following the large-scale invasion by Russia, the future of postwar Ukraine is being sketched: in social media and public discussions, by launching reconstruction initiatives, and, most recently, by establishing the National Council for the Recovery of Ukraine from the War. These discussions, both in Ukraine and internationally, invite revisiting the histories of previous ‘postwars,’ mostly the recovery and rebuilding efforts after WWI and WWII, but also post-Chornobyl (Chernobyl) and post-Cold War. Contemporary discussions may shed new light on the previous story of postwar recoveries, while recoveries in the past may offer valuable perspectives for ongoing debates, such as the questions of entangled relations between political and expert powers; participation and shared authority; the challenge of navigating local and international expert knowledge in rebuilding communities and localities, and the potential of architecture in coping with trauma. Architecture and urban planning have a key role in the process, which can bring change not only to the physical materiality of place, social relations and communities, but also to the ways architecture and planning are imagined and practiced.

Varlıkların temel değeri üzerinde etkisi olması gereken bilgi dışında yer alan ve rasyonel temelli alım satım işlemi dışında yeni bir habere dayalı olmayan işlemler olarak tanımlanabilen gürültüye dayalı işlemin finansal varlıkların fiyatları üzerinde bozucu bir etkiye sahip olduğu ve gürültüye dayalı işlem riskini oluşturduğu yaygın bir görüş olarak literatürde yer almaktadır. Gürültü olgusunun varlığı ve varlık fiyatları üzerindeki etkisinin ölçülmesi ise birbirinden oldukça farklı yöntemlerle yapılmaya çalışılmaktadır. Bu çalışmada 20.04.2000-17.09.2021 döneminde BİST-100 endeksi finansal zaman serilerinin gösterdiği değişen varyans, kalın kuyruklu dağılım ve bilgiye karşı asimetrik reaksiyona uygun bir yaklaşım olan EGARCH-M yöntemi ile modellenerek getiri oranı üzerindeki gürültü ve bilgi etkilerinin tahmin edilmesi amaçlanmıştır. Böylelikle alternatif gürültü ölçüm yaklaşımlarının literatürde belirtilen dezavantajlara sahip olmayan bir yöntemle gürültünün Borsa İstanbul’daki varlığının ölçümü ve gürültü riskinin zaman içindeki değişimi ortaya konulmuştur. Elde edilen bulgular piyasaya giren bilginin BİST-100 endeksi volatilitesi üzerindeki etkisinin asimetrik olduğu, olumsuz bilgilerin etkisinin olumlu bilgilerden daha fazla olduğu, gürültünün BİST-100 endeksi getiri oranları üzerindeki etki ortalamasının artırıcı, bilginin ise düşürücü olduğu ancak her iki etki ortalamasının da istatistiksel olarak anlamlı olmaması nedeniyle tahmin edilebilirliklerinin güç olduğu şeklindedir.
Las Grandes Corporaciones Agroindustriales Y La Agricultura Contractual: Aproximaciones Teóricas
Authors: Orozco Christian
Published: November 2022

La agricultura contractual constituye una modalidad productiva y comercial de largo recorrido en el tiempo y el espacio; por esta razón, se considera esencial aproximarse a las distintas interpretaciones de sus determinantes. En este sentido, el presente artículo analiza las aportaciones teóricas e interpretativas que desde las principales corrientes y escuelas de pensamiento económico se han planteado en torno a los factores que han contribuido decisivamente en el desarrollo de la modalidad productiva y comercial del contrato en la agricultura, especialmente desde la perspectiva de las grandes corporaciones agroindustriales. La metodología aplicada en esta investigación es la revisión de literatura. Las corrientes investigadas son la francesa, la anglosajona y la latinoamericana. Al final, se concluye que a través de la agricultura contractual se produce una refuncionalización de la economía agraria; los contratos constituyen una estrategia empresarial para abastecerse de suministros agrícolas; y los resortes con los que cuentan las grandes corporaciones agroindustriales para fomentar esta modalidad productiva y comercial son de mercado, contractual-informales y tecnológicos
Production of gutturals by non-native speakers of Arabic
Authors: Mashaqba Bassil , Huneety Anas , Abu Guba Mohammed , Al-Duneibat Bara'ah
Published: November 2022

This paper investigates the production of Arabic gutturals by native (NSs) and non-native speakers (NNSs) of Arabic. A total of 40 participants, 20 NSs and 20 NNSs were recruited. 240 tokens were collected using two major methods: free speech and nonsense word testing. Using PRAAT software (version 6.1.01), the tokens were analyzed acoustically to measure F1 and F2 and to signal the (non)significance of the difference between the target groups and auditorily to rate gutturals’ production accuracy by NNSs. F1 and F2 of the vowels neighbouring the gutturals were normalized using the speaker extrinsic Labov ANAE method (NORM version 1.1) to eliminate the effects of gender and age. The study demonstrates some important findings: in terms of quality, the F1-F2 approximation varies by nativeness in that NNSs were unable to make enough coarticulatory effects associated with Arabic gutturals. This result indicates that NNSs do not make a sufficient primary constriction in the posterior regions of the vocal tract. Relying on auditory judgments of accuracy, the most accurately produced gutturals by NNSs were the voiceless glottal fricative /h/ followed by the voiceless glottal plosive /ʔ/, and the lowest ranked gutturals were the voiced velar fricative /ɣ/ and the voiced pharyngeal fricative /ʕ/. The study concludes that non-temporal cues especially F1 and F2 are essential correlates to Arabic gutturals’ production. Because such factors are language-specific, they should be taken into consideration in the teaching of Arabic as a second/foreign language.

Problem-solving is essentially a process with schematic, conversational and procedural attributes. This skill set is essential for graduates to solve problems they encounter in their social, academic, and professional lives. A huge portion of problem-solving practice may be found in debating. Due to the magnitude of problem-solving skills, this study aimed to investigate the synergetic role of debating practice on problem-solving language development in a corpus-assisted way. This study compiled a learner corpus containing 32,3975 tokens of 28 transcribed debates from the World University Debating Championship on YouTube (see Appendix). A corpus-based analysis by AntConc explored the schematic features of problem-solving patterns in terms of type-token ratio, collocation, standardized frequencies, and concordance lines. The findings show that problem-solving representations were outstanding in the debating learner corpus with a high type-token ratio, Problem schema, and Solution schema. Patterns concerning problem, need, and solution(s) appear with a highly standardized frequency. In addition, a concordance analysis of the most frequent keywords revealed the schematic variations of problem-solving functions employed by debaters. The genre analysis confirms the presence of problem-solving procedures in the sequence of the Situation, the Problem, the Response or Solution, and the Evaluation and its conversational inherency under diverse opinions. These findings provide corpus evidence for the schematic, conversational and procedural representation of problem-solving. Thus, debating practice is a significant vehicle to facilitate students’ problem-solving sense development of knowledge schema, conversations, and genre prototypes.

Research has thus far shown that students' interest and active involvement are pivotal in the language learning process. However, there is a paucity of research examining how an English literary text can be exploited to bolster student engagement in an Indonesian EFL setting. Occupying this niche, this article focuses on the student's responses and the application of imaginative re-creation to the short story ("The Gift of the Magi"). Twenty-eight 3rd-semester English students taking the "Basic Reading Comprehension" course at a private university in Semarang (Indonesia) participated in this study. Couched under the reader-response theory, the students were asked to imaginatively recreate meanings after they read the text. The results showed that the students were actively involved and responded to the text during the learning process in various ways. Several students' responses were still very close to the original text, while the others were fairly different from the original. Throughout the learning process, the students actively interacted with texts and engaged with other learners. These interactions help to create a relaxing environment for the learners, which aids comprehension and encourages creativity in the creation of a new text. These findings shed light on the further development of students' creative writing in EFL teaching.

Since the beginning of the Covid-19 Pandemic, the world has heavily relied on the internet to acquire information. The Pandemic is growing as a complex information discourse with so many texts from many sources. Various texts about Covid-19 certainly have various meanings for their readers. It is interesting to see an information resource that presents information in many languages in parallel. This study aims to reveal the global meaning of the parallel Indonesian and English texts of Covid-19 released by the World Health Organization. More specifically, this study examines whether parallelism in the two versions of the same text will present differences in the global meaning of each text; and whether there are social and political aspects that potentially affect the differences. The data for this study consists of two pairs of question-and-answer texts about Covid-19 published by WHO in English and Indonesian. This study used van Dijk's Critical Discourse Analysis framework at the macrostructure level. This study collected all texts and macro rules (deletion, generalization, and construction) have been applied to reduce information at the texts’ micro level to macropropositions at the macro level or the global topics/themes of discourse. There are some differences in the Indonesian text when compared to the original English text. Some of these differences may appear in the Indonesian translated version as a response to Indonesia's social and political conditions during the Covid-19 pandemic.

Vocabulary is one of the main components in learning a new language which provides the ground for language learners to learn and use the language. In this regard e-portfolio, as a recent and novel assessment technique, can have the potential for vocabulary development. This study aimed at investigating the effect of portfolio assessment on Iranian EFL guidance school learners’ vocabulary learning and retention. To this end, 92 guidance school students in the seventh, eighth, and ninth grades, were selected as the participants of the study. They were randomly assigned into two experimental and control groups. While the control group followed the conventional class quizzes the experimental group practiced e-portfolio assessment. The participants in the experimental group were asked to create their e-portfolios and keep a record of what they learned during and after the online sessions. They were also asked to include the reflection sheets in their e-portfolios. Three parallel tests as a pre-test, an immediate post-test, and a delayed post-post were used to gather data about the effect of portfolio assessment in each grade (a total of nine tests). The results of a one-way ANCOVA revealed that the participants of the experimental group outperformed the participants of the control group in terms of EFL vocabulary learning and retention. Considering the outcomes, the study presents some implications for practitioners including language teachers, curriculum and course developers, and language learners.

Developing strong reading skills in children is crucial to overcoming language and academic barriers and ensuring future success in education.  The extent of phonological awareness (PA) substantially affects children's reading ability (Hoff, 2014). Thus, the goal of the study was to document the success rate of ten Filipino kindergarten pupils enrolled in one public school in Calaca who underwent twenty sessions of 30-minute integrated PA intervention. The study employed mixed methods research utilizing intervention design. The quantitative results were taken from a single-group pretest-posttest, and the qualitative results were taken from a thematic analysis of interviews of educational assistants and kindergarten teachers at three-time points. Muñoz et al.’s (2018) pedagogical framework and Cummins’ (1979) Linguistic Interdependence Theory provided foundational support in analyzing how PA intervention in the mother tongue assists children in gradually promoting their reading outcomes in the mother tongue and English. Results show significant differences in PA and letter knowledge in Batangas Tagalog and English before and after the intervention. Batangas Tagalog scores show a very high significant positive correlation. Additionally, observations reveal positive changes among the pupils after undergoing the intervention. The study demonstrates that PA intervention in the mother tongue potentially provides a promising and sustainable way to improve the early reading skills of Filipino kindergarten pupils.

The existence of the COVID-19 pandemic forces the Indonesian government to carry on online learning at all education levels, to keep the teaching and learning going on. For students, this ongoing online learning has brought about various impacts on their online learning success. One important factor determining online learning success is students’ interaction. Thus, paying more attention to whether an online learning environment has promoted the students’ interaction is crucial to creating successful online learning. This study aimed to investigate the dimensions of students’ interaction in the online listening learning environment. Moreover, this study also tried to explore how students perceived the interaction in the online listening learning environment. There were 78 students majoring in English Education as participants in this study. A convergent mixed-method was applied in this study, in which the results of the quantitative and qualitative data analysis were brought together. A modified questionnaire of OLLES (Online Learning Environment Survey) and a close-ended interview were carried out to gather the data. The results showed that the dimensions of interaction in the online listening learning environment had a statistically significant high rating. The interaction between the lecturer and the students placed the highest among all of the dimensions. Overall, all the dimensions of interaction in online listening learning were highly perceived by the students. The implications suggested that providing well-designed authentic materials, collaborative activities, and asynchronous models were needed to support the students’ online learning performance.
Staying local in a global discourse: A study of comments on selected minifictions by a Sundanese woman writer in Fiksimini Basa Sunda Facebook Group
Authors: Safrina Raden
Published: November 2022

This paper examines the social meanings from interactions of a Facebook group which posts mini fictions in the Sundanese language. The examination was more specifically focused on comments for mini fiction posts written by a woman writer. Following the idea of locality as essentially ‘a situatedness’ (Ahmed, 2000), the study framed the interactions as locality and situated the locality as it intertwines and intersects with more global issues. The study began by selecting mini-fictions in the Sundanese language that received at least 100 comments from their readers. Interactions arising from comments about the selected texts were examined to situate the intertwine of locality in the texts and the more global responses in the comment sections. Selected interactions were then examined using a Hallidayan critical discourse analysis. Taking situatedness as the focus, the analysis indicates that interpersonal themes attracted comments where locality and globality are situated to construct irony where locality pales in the face of globality. Therefore, it seems that more efforts should be made to strategically situate locality in a more vantage point in the global world.
