The Jebli speech between the media and the city: exploring linguistic stereotypes on a rural accent in Northern Morocco
Authors: Benítez Fernández Montserrat , Guerrero Jairo
Published: November 2022

The symbolic values that speakers attribute to certain linguistic features constitute an important sociolinguistic topic which, barring a few seminal works, has not drawn much attention from scholars working on Maghrebi Arabic, and more specifically, Moroccan varieties. The present paper aims to deepen our understanding of metalinguistic representations of Jebli, a sedentary rural variety of Moroccan Arabic, within the speech communities of Larache and Ouezzane, two urban centres lying on the southern periphery of the Jbala region of Northern Morocco. We first analysed several samples of performed speech taken from an online Moroccan comedy sketch series entitledJebli & Beldi, which includes a character epitomizing the Jebli accent, in order to identify those salient linguistic features that are perceived as being typically Jebli. As these phonetic and morphosyntactic traits are consciously selected in performed speech, it may be assumed that they make up a linguistic stereotype. We then asked a group of informants in the cities of Larache and Ouezzane to describe what they regarded as the typical features of Jebli speech and also their attitudes towards these features. The results of our study show that the features informants named partly coincided with our own sketch-based selection, and their attitudes towards these features were generally negative. These features did not appear in the speech of most informants, suggesting either their absence in their dialect or a deliberate avoidance strategy on their part. A small number in fact used these features but denied doing so, suggesting that the features are socially stigmatized. We argue that the symbolic values ascribed to some typical Jebli features may trigger their avoidance, which in turn may generate linguistic variation and even lead to linguistic change.
Machine learning models can predict the presence of variants in hemoglobin: artificial neural network-based recognition of human hemoglobin variants by HPLC
Authors: Uçucu Süheyl , Karabıyık Talha , Azik Fatih Mehmet
Published: November 2022

Objectives

This article presents the use of machine learning techniques such as artificial neural networks, K-nearest neighbors (KNN), naive Bayes, and decision trees in the prediction of hemoglobin variants. To the best of our knowledge, this is the first study using machine learning models to predict suspicious cases with HbS or HbD Los Angeles carriers state.

Methods

We had a dataset of 238 observations, of which 128 were HbD carriers, and 110 were HbS carriers. The features were age, sex, RBC, Hb, HTC, MCV, MCH, RDW, serum iron, TIBC, ferritin, HbA2, HbF, HbA0, retention time (RT) of the abnormal peak, and the area under the peak of the abnormal peak. KNN, naive Bayes, decision tree models, and artificial neural network models were trained. Model performances were estimated using 7-fold cross-validation.

Results

When RT, the key point of differentiation used in high-performance liquid chromatography (HPLC), was included as a feature, all models performed well. When RT was excluded (eliminated), the deep learning model performed the best (Accuracy: 0.99; Specificity: 0.99; Sensitivity: 0.99; F1 score: 0.99), while the naive Bayes model performed the worst (Accuracy: 0.94; Specificity: 0.97; Sensitivity: 0.90; F1 score: 0.93).

Conclusions

Deep learning and decision tree models have demonstrated high performance and have the potential to be integrated into medical laboratory work practices as a tool for hemoglobinopathy detection. These outcomes suggest that when machine learning models are fed enough data, they can detect a wide range of hemoglobin variants. However, more comprehensive studies with data from a larger number of patients and hemoglobinopathies will be useful for validating our models.

In recent years, various improvements over different graphene synthesis methods are practiced constantly for safer and functional substitutes. Though graphene extraction through Hummers method is one of the former techniques yet but new advancements are always present. Here, we have compared the properties of graphene oxide prepared through conventional Hummers method and simple room temperature approach and it is concluded that conventional Hummers method can be replaced by simple room temperature approach by replacing sodium nitrate (NaNO3) with phosphoric acid (H3PO4) having no change in properties. In comparison to conventional Hummers method, this simple method eliminates need of temperature control and generation of toxic gases. In our case, this one-pot oxidation of graphite powder at room temperature has provided large area production of graphene oxide with 100% conversion.

Published: November 2022

Chronic fibroinflammatory pancreatitis causes irreparable damage to the pancreatic parenchyma. This frequently results in food restrictions, painkiller addiction, and serious quality of life impairment in children. We observed a 13-year-old girl who had previously been hospitalized multiple times and had undergone acute pancreatitis arrived with excruciating abdominal pain and recurrent hematemesis. A chronic intra-pseudocyst bleed and an ampulla of Vater hemorrhage were discovered during an upper gastrointestinal endoscopy. A 3×2×1 cm pancreatic head pseudocyst was discovered on the magnetic resonance cholangiopancreatography, however the computed tomography scan revealed a pancreatic head pseudocyst, pancreatic duct stones, and substantial peripancreatic inflammation. The multidisciplinary team determined that Frey’s surgery was the most efficient method to minimize her suffering. No complications occurred during the healing phase following surgery, and two years later, neither recurrence bleeding nor abdominal pain appeared. In summary, Frey’s method is a secure and efficient intervention when applied by a multidisciplinary team.
Endoplasmic reticulum stress promotes endometrial fibrosis through the TGF-β/SMAD pathway

Published: November 2022

In brief

Intrauterine adhesion (IUA) is one of the main causes of female infertility. This study reveals that endoplasmic reticulum stress activation upregulates the TGF-β/SMAD pathway to induce epithelial–mesenchymal transition and promote endometrial fibrosis in an IUA model.

IUA is a common gynecological disease and is a leading cause of female infertility. Mechanical or infectious damage to the endometrial basal layer can lead to endometrial fibrosis, which is the most common cause of IUA. Endoplasmic reticulum stress (ERS), the transforming growth factor beta signaling pathway (TGF-β/SMAD) and epithelial–mesenchymal transition (EMT) are important factors promoting endometrial fibrosis. The purpose of this study was to determine the up- and downstream regulatory relationships of the above three in the process of endometrial fibrosis. The rat IUA model was induced by double injury method and prophylactic injection of the ERS inhibitor 4-phenylbutyric acid (4-PBA) was given in vivo. The ERS activator tunicamycin and the TGF-β/SMAD pathway inhibitor A 83-01 were used in human endometrial epithelial cells (HEECs) in vitro. Masson’s trichrome, Sirius red staining, immunohistochemistry, immunofluorescence and Western blot analyses were used to determine ERS, TGF-β/SMAD pathway, EMT and fibrosis markers in the uterine tissue and HEECs of the different treatment groups. In animal experiments, ERS and the TGF-β/SMAD pathway had been activated and EMT occurred in an in vivo model of IUA but was suppressed in animals treated with prophylactic 4-PBA. In in vitro experiments, tunicamycin-treated HEECs had increased the activation of ERS, the abundance of TGF-β/SMAD pathway and fibrosis markers while EMT occurred, but the TGF-β/SMAD pathway and EMT were significantly inhibited in the tunicamycin+A 83-01 group. Our data suggest that increased ERS can induce EMT and promote endometrial fibrosis through the TGF-β/SMAD pathway.

Los procesos de homologación y seguimiento de las titulaciones universitarias son uno de los mecanismos utilizados para garantizar la adecuación de la oferta formativa. Sin embargo, las investigaciones existentes en esta área son más bien escasas. Por ello, este estudio se propuso evaluar los resultados de acreditación de los másteres en Profesorado de Enseñanza Secundaria Obligatoria y Bachillerato, Formación Profesional y Enseñanza de Idiomas de las universidades públicas y privadas españolas, así como comparar la valoración obtenida entre ambos tipos de instituciones. Se realizó un estudio descriptivo-comparativo mediante el análisis de los últimos informes de acreditación (54 documentos) de las distintas agencias de calidad. La revisión realizada permitió apreciar una notable heterogeneidad en los parámetros y en las escalas de valoración utilizadas. El criterio con más informes favorables fue el de Personal de apoyo, recursos, materiales y servicios. Por el contrario, Organización y desarrollo y Resultados de aprendizaje fueron los que obtuvieron el mayor número de valoraciones negativas. El análisis comparativo entre las instituciones privadas y públicas permitió advertir, además, que las primeras tuvieron valoraciones más favorables. A la vista de tales divergencias, se concluye la necesidad de armonizar los procesos y mecanismos de acreditación de este máster en España.

En este trabajo se presenta una lista actualizada de los registros de especies de peces de la cuenca del río Ucayali, Perú, provenientes de datos publicados y no publicados. Los resultados muestran que la cuenca del Ucayali presenta una ictiofauna rica y diversificada con el registro de 734 especies distribuidas en 15 órdenes, 49 familias y 292 géneros. La Ictiofauna está compuesta por peces miniatura (4%), peces pequeños (39%), medianos (41%), grandes (13%) y gigantes (3%). Los grupos dominantes son los Characiformes (312 especies, 43.0 %), Siluriformes (270 especies, 36.8%), Gymnotiformes (51 especies, 6.9%), y Cichliformes (50 especies, 6.8%). Parte de la ictiofauna es compartida con cuencas adyacentes como Marañón, y Amazonas peruano, principalmente en la región de confluencia, lo que contribuye a la notable diversidad de peces en la cuenca. Se observó una alta riqueza de especies con distribución restricta de los géneros Orestias, Astroblepus, Trichomycterus, Hemibrycon, entre otras especies, que ocurren en la región de cabeceras. Estimativos de riqueza de especies considerando su distribución por cada 100 m de altitud, indican que la cuenca del Ucayali esta subestimada, esperándose encontrar hasta 1125 especies. Los resultados aquí presentados son antecedentes que coadyuvaran a la toma de decisiones con fines de conservación y desarrollo sustentable en la región amazónica.
Associations Between Global Competence and Right-Leaning Population: Evidence From PISA 2018 and European Social Survey

Published: November 2022

This study explores the relationship between 15-year-olds results in the PISA 2018 assessment of global competence and citizens’ political views. In particular, we look at the correlations of 18 EU nation-states citizens’ political preferences (right-leaning) and students’ non-cognitive skills, attitudes, and values. Data from the OECDs’ PISA global competence and European Social Survey for the year 2018 were used. After the analysis, it can be presumed that the higher share of the right-leaning population in the country is associated with lower students’ global competencies.

The multidimensionality of the aging process involves changes in different capacities. The age-friendly cities strategy addressed the need for adaptations in urban spaces that meets the demands of older people’s wellbeing. Thus, the aim of this study was to explore how Participative Mapping and World Café techniques could assist in identifying challenges to the delivery of services and resources to create communities that promote active aging, from the perspectives of older people and stakeholders. The techniques generated co-constructed discussion and shared understandings about the barriers residents face in negotiating and accessing services. Demands associated with the precariousness of local infrastructure, the absence of leisure activities, and a generalized feeling of insecurity in their neighborhoods were recurring themes. The demands led to the conclusion that for healthy aging, the interrelation of objective and subjective factors that take into
A corpus-based search for machine translationese in terms of discourse coherence
Authors: Jiang Yue , Niu Jiang
Published: November 2022

Earlier studies have corroborated that human translation exhibits unique linguistic features, usually referred to as translationese. However, research on machine translationese, in spite of some sparse efforts, is still in its infancy. By comparing machine translation with human translation and original target language texts, this study aims to investigate if machine translation has unique linguistic features of its own too, to what extent machine translations are different from human translations and target-language originals, and what characteristics are typical of machine translations. To this end, we collected a corpus containing English translations of modern Chinese literary texts produced by neural machine translation systems and human professional translators and comparable original texts in the target language. Based on the corpus, a quantitative study of discourse coherence was conducted by observing metrics in three dimensions borrowed from Coh-Metrix, including connectives, latent semantic analysis and the situation/mental model. The results support the existence of translationese in both human and machine translations when they are compared with original texts. However, machine translationese is not the same as human translationese in some metrics of discourse coherence. Additionally, machine translation systems, such as Google and DeepL, when compared with each other, show unique features in some coherence metrics, although on the whole they are not significantly different from each other in those coherence metrics.
Autonomy support, critical thinking, and motivation as key predictors of translator trainees' strategic competence
Authors: Bolaños-Medina Alicia , Núñez Juan L.
Published: November 2022

This study consists of a correlational and regression analysis of certain factors involved in the practice of translator training, as perceived by translator trainees. More precisely, our aim is to examine the relationships between translator trainees' strategic competence (as the dependent variable), and autonomy support, amotivation and critical thinking (as the independent variables) in the translation classroom. Building upon recent advances in educational and social psychology, we have relied on Self-determination theory (Deci & Ryan, 2011) as an interpretative frame of reference. After revising the concept of translators' strategic competence, the main contributions in the field of translators' motivation are also reviewed and the notions of autonomy support and critical thinking are approached from the perspective of both psychology and translatology. Our findings seem to point to the fact that autonomy support and critical thinking can play a facilitating role in the development of strategic competence in undergraduate translator students, who may also benefit from both when they encounter new challenges in real professional settings. Finally, the implications for translator training are discussed.

Authors: Zhdanova E. V. , Kostolomova E. G. , Volkova D. E. , Zykov A. V.
Published: November 2022

Rheumatoid arthritis (RA) ranks first among chronic joint diseases. The disease often affects people at their working age, being accompanied by significant decrease in the life quality of patients and their early disability. Rheumatoid arthritis is an immunoinflammatory rheumatic disease. Therefore, the immune system provides evolving focus of primary damage, its persistence and periodic exacerbation. Elucidation of intercellular relationships mediated by cytokines at various stages of the chronic inflammatory process is required in order to develop immunotherapeutic approaches, aimed for both recovery from exacerbations and maintenance of remission state. Purpose of our study was to evaluate cellular composition and cytokine profile of synovial fluid in the patients with rheumatoid arthritis at acute phase and in remission state.

We have studied the samples of synovial fluid taken in 60 patients with rheumatoid arthritis, with 30 subjects being at acute stage of the disease, and 30 patients in remission. Cellular composition and cytokine profile were assessed in the clinical samples. There were 21 women and 9 men at the acute stage (57.0±15.4 years old), with the disease duration of 8.55±6.9 years. The average age of 19 women and 11 men examined in remission state was 53.5±10.9 years, with comparable duration of illness (6.9±5.8 years). The leukocyte phenotyping was performed with a CytoFLEX flow cytometer (Beckman Coulter, USA). The cytokine contents were measured by enzyme immunoassay using a standard set of reagents from the “Proteinovy Contour” LLC (Russia). The results were registered by a Multiscan photometer (Labsystems, Finland).

During the disease exacerbation, the leukocyte contents in synovial fluid increased 2.4-fold, as compared to the remission values. The cellular infiltrate was represented by neutrophils, whereas the contents of lymphocytes and monocytes did not change. Increased migration of neutrophils was accompanied by an 8-fold increase in TNFα levels, compared with remission state, and IL-1β levels were increased by 6.3 times. The absolute number of CD3+T lymphocytes, CD16+CD56+B cells, and CD3-CD19+NK during exacerbation was similar to the remission levels. However, the number of T cell subpopulations was changed, i.e., the number of CD4+ lymphocytes was decreased, and CD8+ cell counts were increased, like as numbers of Treg lymphocytes and NKT cells which showed a significant increase. A 4.3-fold increase in the IL-4 concentration during the RA exacerbation suggested the predominance of Th2 immune response. During remission, the concentrations of IL-6 and IFNγ in synovial fluid were increased, respectively, by 1.5 times and by 2.5 times, which is typical for activated Th1 response.

Abstract Considering the unexplored relationship between leadership, organizational virtues, and human resource management practices, the purpose of this paper is to test a structural model of mediation between leadership and human resource management, being organizational virtues the mediating variable. We performed a survey with 673 employees in Brazil, resorting to Structural Equation Modeling to analyze the data. Findings show that organizational virtues mediate the relationship between leadership and HRM practices. We confirm the positive effect of leadership on organizational virtues, the influence of organizational virtues on HRM practices, and the impact of leadership on HRM practices. This paper contributes to the literature on human resource management and organizational behavior, particularly concerning investigations that deal with antecedents of HRM practices.

Abstract Background Although gym club instructors are closely linked to health and well-being, this group of workers shows specific characteristics that may favor the involvement in musculoskeletal disorders in their occupational routines. Objective To identify the prevalence of knee, low back, and disabling pain and their association with sociodemographic, nutritional, and occupational variables in instructors from gym clubs in the city of Pelotas, southern Brazil. Method A census-type study was carried out with all professionals working at gym clubs (n=497). Crude and multivariable analyses were performed considering “sex”, “age”, “income”, “occupational physical activity”, “time working at the gym clubs” and “modality performed” as exposures. Outcomes were disabling pain, and knee and low back pain. Results The disabling pain affected 20.9% of the workers and was associated with the gym clubs modality performed and with the working longest time in the gym clubs. Half of the professionals related to low back pain in the previous year. This outcome was associated with the age (inversely), of females and Pilates instructors. The knee pains affected, in the last year, 41.5% of the professionals; there was a significant association between age (inversely) and time of work in the gym clubs. Conclusion The instructors had a high prevalence of the three outcomes analyzed. Those who have been working longer time at gym clubs, women, youngers, Pilates, or gymnastic instructors were at an increased risk of presenting the outcomes.

Results: participants answered 1632 questionnaires. Only 38% of nurses work with adolescents, 11.2% exclusively. Professionals were divided according to the median length of professional experience in groups A and B (≤5 years and >5 years). Drug addiction (p=0.01) and working with a multidisciplinary team (p=0.04) were significantly more reported in group B. Routine follow-up (p=0.02) and questioning about sexual or physical violence (p=0.03) were significantly more performed by professionals from group A. Conclusion: this study identified the need for a care protocol that can be replicated on a large scale and that includes the treatment and the particularities of adolescents to improve adherence and the transition into adult care.

Abstract Objective: investigate the influence of health literacy on the assessment of COVID-19 threat to health and the intention not to be vaccinated among Brazilian adolescents. Method: cross-sectional study with 526 Brazilian adolescents aged 14 to 19 years. Socioeconomic aspects, health-disease profile, health literacy, health threat by COVID-19 and intention not to be vaccinated were analyzed by bivariate association and multiple linear regression with Poisson response. Results: higher health literacy score (p=0.010), cardiovascular disease (p=0.006), lower income (p=0.000), and living in the North region (p=0.007) were factors that contributed to feeling more threatened by COVID-19. Health literacy did not influence the intention not to be vaccinated (p=0.091), whose prevalence was lower among adolescents in the Southeast region when compared to those in the North region (p=0.010), among those who attended higher education (p=0,049) and those with higher income (p=0.000). Conclusion: health literacy influenced the perception of COVID-19 threat, but not the intention not to be vaccinated. Assessment of COVID-19 threat to health and prevalence of the intention not to be vaccinated were influenced by the region of residence, income, and education, which reinforces the importance of social determinants of health in this context.

Resumo Objetivo: investigar a influência do letramento em saúde na avaliação da ameaça à saúde pela COVID-19 e sobre a intenção de não se vacinar de adolescentes brasileiros. Método: estudo transversal com 526 adolescentes brasileiros de 14 a 19 anos. Aspectos socioeconômicos, perfil saúde-doença, letramento em saúde, ameaça à saúde pela COVID-19 e intenção de não se vacinar foram analisados por associação bivariada e regressão linear múltipla com resposta Poisson. Resultados: maior pontuação de letramento em saúde (p=0,010), doença cardíaca (p=0,006), menor renda (p=0,000) e morar na região norte (p=0,007) foram fatores que contribuíram para o sentimento de maior ameaça pela COVID-19. O letramento em saúde não influenciou a intenção de não se vacinar (p=0,091), cuja prevalência foi menor entre os adolescentes do Sudeste quando comparados aos do Norte (p=0,010), entre os que cursavam o ensino superior (p=0,049) e entre aqueles com maior renda (p=0,000). Conclusão: letramento em saúde influenciou a percepção da ameaça da doença, mas não a intenção de não se vacinar. Avaliação da ameaça à saúde pela COVID-19 e a prevalência da intenção de não se vacinar foram influenciadas pela região de residência, renda e escolaridade, o que reforça a importância dos determinantes sociais da saúde nesse contexto.

Resumo Objetivo: compreender as rupturas biográficas causadas pela pandemia da COVID-19 sobre adolescentes e jovens homens trans e pessoas transmasculinas no contexto do Brasil. Método: estudo qualitativo - survey on-line, multicêntrico. Participaram 97 homens trans e 22 pessoas transmasculinas, autoidentificados, que responderam formulário semiestruturado em duas etapas. Os dados foram submetidos à Análise de Conteúdo Temática Reflexiva. Realizou-se a interpretação com base sociológica, a partir do conceito de ruptura biográfica. Resultados: derivadas cinco categorias: interrupção da hormonização, cirurgias e acompanhamento especializado; desconfortos precipitados pela ruptura das características masculinas, autoimagem, autopercepção e identidade; vulnerabilidade a partir das perdas de familiares e pessoas significativas, emprego e fragilização das redes de apoio; emergência de problemas psicoemocionais, como perda do sentido da vida; demandas para o cuidado de enfermagem e valorização da vida de adolescentes e jovens transmasculinos no pós-pandemia. Conclusão: as rupturas biográficas provocadas pela pandemia ameaçaram as identidades de homens trans e pessoas transmasculinas de adolescentes e jovens, produziram degradação e descontinuidade das biografias, conduzindo-os à perda de sentido da vida. Profissionais de enfermagem podem ser estratégicos e essenciais na superação das ameaças, intervindo antecipadamente.

Resumen Objetivo: estimar la prevalencia de problemas emocionales y de comportamiento en adolescentes en el contexto de la pandemia de COVID-19 e explorar la percepción de los adolescentes acerca de los problemas emocionales y de comportamiento identificados. Método: un estudio de método mixto de diseño explicativo secuencial. Participaron 479 adolescentes de 15 a 18 años de una capital de la región Centro-Oeste brasileña. Resultados: de los 479 participantes, la media de las edades fue los 16,03 años (DP=1,01). La prevalencia de PEC fue del 61,17% y había una diferencia en cuanto al sexo (ORb=2,93; p<0,01). Las mayores prevalencias se relacionaron con los problemas de relación entre pares (54,49%) y con los síntomas emocionales (52,40%). Los adolescentes notaron un aumento de soledad, ansiedad, tristeza, alejamiento de amigos y dificultades de socialización durante la pandemia. Conclusión: se clasificó la mayoría de los adolescentes investigados con problemas emocionales y de comportamiento, y las chicas presentaron una mayor probabilidad de manifestarlos en comparación con los chicos. Las declaraciones de los adolescentes refuerzan los resultados cuantitativos. Así, se señala la necesidad de implementar acciones para promover y restaurar la salud mental de los adolescentes, para mitigar los impactos socioemocionales de la pandemia de COVID-19 en esa población.
