Identification of discontinuous parameters in double phase obstacle problems
Authors: Zeng Shengda , Bai Yunru , Winkert Patrick , Yao Jen-Chih 
Published: August 2022

Abstract
In this article, we investigate the inverse problem of identification of a discontinuous parameter and a discontinuous boundary datum to an elliptic inclusion problem involving a double phase differential operator, a multivalued convection term (a multivalued reaction term depending on the gradient), a multivalued boundary condition and an obstacle constraint. First, we apply a surjectivity theorem for multivalued mappings, which is formulated by the sum of a maximal monotone multivalued operator and a multivalued pseudomonotone mapping to examine the existence of a nontrivial solution to the double phase obstacle problem, which exactly relies on the first eigenvalue of the Steklov eigenvalue problem for the

-Laplacian. Then, a nonlinear inverse problem driven by the double phase obstacle equation is considered. Finally, by introducing the parameter-to-solution-map, we establish a continuous result of Kuratowski type and prove the solvability of the inverse problem.

), based on some elaborate analysis of this system’s intrinsic singular structures, we establish the local-in-time well-posedness of regular solution with arbitrarily large initial data and far field vacuum in some inhomogeneous Sobolev spaces by introducing some new variables and initial compatibility conditions. Note that due to the appearance of the vacuum, the momentum equations are degenerate both in the time evolution and viscous stress tensor, which, along with the strong coupling between the fluid and the radiation field, make the study on corresponding well-posedness challenging. For proving the existence, we first introduce an enlarged reformulated structure by considering some new variables, which can transfer the degeneracies of the radiation hydrodynamic equations to the possible singularities of some special source terms, and then carry out some singularly weighted energy estimates carefully designed for this reformulated system.
Early Bilingual Vocabulary Development Among Low-SES Ethnic Minority Learners in China: The Case of Uyghur and Kazak Children
Authors: Li Guofang , Yin Xiaorong , Ji Xuejun (Ryan) 
Published: August 2022

Abstract
Vocabulary knowledge is one of the most important aspects of language development. For bilingual students, early vocabulary development often predicts their future bilingual success. This paper examines early bilingual receptive vocabulary knowledge of ethnic minority children (N=135) from two large ethnic language communities (Uyghur and Kazak) in three national-level poverty-stricken counties in Xinjiang, China. The children’s bilingual vocabulary knowledge was assessed using translated versions of the Peabody Picture Vocabulary Test-IV (PPTV-IV) in Putonghua (PTH) and their mother tongue (MT) Uyghur or Kazak. Data were analyzed through four General Linear Models (GLM). The analyses showed that both groups scored higher in MT vocabulary knowledge than that in their PTH, although the Kazak students’ MT vocabulary scores were lower than those of the Uyghurs. While gender, age, L1, or residence location were not significant factors in differences across the two groups in PTH, among the Kazak children, the main effect of age was significant in MT; and among Uyghur children, residence location had a significant effect. The two groups also differed in patterns of acquisition in different parts of speech (nouns, verbs, and attributes) with Uyghur children performing strongest in MT and PTH verbs. The findings have important implications for ensuring the quality of early bilingual education among impoverished Chinese minority communities.
Research on the Students’ Attitudes Towards Multilingualism: Li Minority Students in Hainan
Authors: Yue Mei , Fan Xujie 
Published: August 2022

Abstract
Recent research has emphasized that attitude is key to language learners’ learning outcomes. More specifically, language learners’ feelings about languages and language learning may affect their study behavior and willingness to engage with a second or foreign language. Few studies on language attitudes have been conducted with ethnic minority groups in China. As such, influencing factors (e.g., gender, language proficiency) have not gained sufficient attention. The present study aims to explore language attitudes, especially towards multilingualism, among members of the Li minority group in Hainan, China. First, we conceptualized and validated a questionnaire on attitudes towards multilingualism. Exploratory factor analysis and confirmatory factor analysis verified the survey’s validity. Then, we examined how selected sociodemographic variables (e. g., gender and language proficiency) influenced students’ attitudes towards multilingualism. Hierarchical regression was performed to ascertain the contribution of each predictor variable to learners’ attitudes towards multilingualism. Results revealed no significant relationship between gender and language attitudes but found a significant impact of students’ language proficiency level on their attitudes towards multilingualism. Implications for minority students’ multilingual learning were discussed based on the findings.
English Teachers’ Beliefs About Multilingual Awareness in L3 Learning and Their Teaching Practice in Chinese EFL Context
Authors: Wu Baiyinna 
Published: August 2022

Abstract
Teachers’ beliefs toward multilingual awareness in target language learning play a significant role in shaping learners’ attitudes to language awareness, affect learners’ linguistic behavior and teachers’ teaching practice. Therefore, the present study was aimed to explore English teachers’ beliefs about Inner Mongolian university students’ multilingual awareness in L3 learning and their teaching practice in Chinese EFL context. One hundred English teachers from six universities in Inner Mongolia, China, participated in this investigation. The data was collected through a questionnaire and teacher interviews. The results indicate that English teachers hold positive attitudes to multilingual awareness in general; however, there are belief differences between Mongolian and Han teachers; there exist discrepancies between English teachers’ beliefs about multilingual awareness and their teaching practice, and social-cultural environment, family language policy, teacher identity, learning experience, teaching materials, and, more importantly, teachers’ lack of awareness of fostering learners’ multilingual awareness lead to the discrepancies. The present research highlights the necessity of raising teacher awareness of cultivating multilingual awareness in future teacher development and emphasizes the significance of exploring the potential cognitive advantages of multilingualism in promoting L3 learning and developing English learners’ multilingual competence in the EFL context in China.
Developing Students’ Intercultural Communicative Competence Through Threads of Personal Experiences: A Reflective Approach
Authors: Liu Yi 
Published: August 2022

Abstract
With the development of world globalization, English works as a lingua franca for intercultural communication among different cultures in the world. This shift implies that introducing solely English native speaking cultures to students is not sufficient for their needs. This paper depicts the reflective teaching process of my ten years of experience of teaching intercultural communication. The paper describes how the teacher systematically reflects on the practice of teaching, continuously revises the curriculum, and finally formulates an efficient model of integrating students’ personal experiences into developing students’ intercultural communicative competence and awareness. This reflective study attempts to provide some pedagogical implications for intercultural communication education.
Effects of Written Corrective Feedback on College EFL Students’ Writing Accuracy and Linguistic Knowledge Acquisition
Authors: Sun Haiyang , QI Wenbo 
Published: August 2022

AbstractSet at the interface between second language acquisition and second language writing, this study examines how different types of written corrective feedback (WCF) influence the writing accuracy of Chinese college students learning English as a Foreign Language (EFL) and whether WCF facilitates the students’ grasp of the focused linguistic knowledge. The participants (n = 60) were divided into direct correction group (n = 20), indirect error-coding group (n = 20) and metalinguistic explanation group (n = 20). The three groups wrote four essays in two months and received WCF for the first three essays on the five targeted error types, namely tense errors, confusion of different forms of a word, word (articles, prepositions, etc.) missing, errors in subject-verb agreement and inappropriate verb-noun collocations. The results show that all three types of WCF improved students’ writing accuracy but none of them had any statistical advantage, and the metalinguistic WCF was more effective than the other two forms in facilitating the acquisition of the targeted linguistic features. These results shed some light on teaching and consolidation of language points through writing in EFL contexts.

Published: August 2022

Abstract

Objectives
The occurrence of a uterocutaneous fistula (UCF) as an uncommon and severe complication of caesarean section (CS). The aim of this study was to describe two cases of UCFs after CS and to discuss about symptoms, diagnosis and treatment.

Case presentation
Both women few days after CS had surgical site infection, fever and elevation of lab inflammation markers. bacterial culture of the wound drainage was positive for Escherichia Coli and Enterococcus Faecalis.

Conclusions
Fistula between uterine and skin is a rare condition but should be considered with signs of inflammation after cesarean section; 2D/3D ultrasound evaluation appears to be useful for diagnosis of UCFs when combined with CT fistulography and MRI in order to obtain early diagnosis and, consequently, a conservative surgery.
Chagasic heart failure in a pregnant woman in a non-endemic area: case report and long-term follow-up
Authors: Gastañaga-Holguera Teresa , González-González Virginia , Merino-Amador Paloma 
Published: August 2022

Abstract

Objectives
Chagas disease (CD) is caused by infection with the protozoan Trypanosoma cruzi, a parasite that nests in various tissues, causing irreversible cardiac damage in 30% of patients with chronic disease and neurological or digestive lesions in 10%. CD is now found in areas receiving migrant populations where no vector-borne transmission occurs. Chagasic cardiomyopathy (CC) is the most serious complication of the chronic phase of CD and the major cause of morbidity and mortality among patients with CD.

Case presentation
Bolivian woman at 38 weeks of gestation was admitted at the emergency room with the diagnosis of congestive heart failure. Cesarean section was performed and maternal hypotension and uterine atony occurred. Dilated myocardiopathy with severe left ventricle dysfunction was diagnosed. The patient referred positive serology for T. cruzi and polymerase chain reaction (PCR) was positive so benznidazole therapy was started. She was discharged due to progressive improvement with cardiological treatment and implantable cardioverter defibrillator was placed 5 years later for the prevention of sudden cardiac death.

Conclusions
The diagnosis of CC in non-endemic areas requires a high index of suspicion and it is based on serology. Antiparasitic drugs are almost 100% effective in infected newborn babies and highly effective in the treatment of patients in the acute stage of the disease. However, the efficacy of both drugs decreases the longer a person has been infected. Treatment of CC that causes chronic heart failure is similar to that in non-Chagasic etiology.

Published: August 2022

Abstract
Notwithstanding the benefits that oil provides as a source of energy, society also recognizes the environmental problems caused by its use. We evaluated eight coastal sites in the central area of the Gulf of Mexico. At these sites, 14 hydrocarbons were detected which belong to compounds formed by carbons ranging from C9 to C27. The hydrocarbons with the highest concentrations were n-nonane (3.07 ± 1.60 mg L−1), carbazole (0.93 ± 0.12 mg L−1) and benzo [a] pyrene (1.33 ± 0.71 mg L−1). The hydrocarbons found belong mostly to medium fraction hydrocarbons, which are mostly found in fuels such as diesel. Therefore, this fuel was used as a carbon source or substrate in bubble column bioreactors. The capacity of non-genetically modified organisms to degrade microbial hydrocarbons was evaluated using a mineral medium for a period of 14 days. Suspended solids increased from 0.8 to 2.94 g L−1. Diesel consumption was achieved in 12 days of operation.
Cultural concept, movement, and way of life:jeitinhoin words and gestures
Authors: Schröder Ulrike , Streeck Jürgen 
Published: August 2022

AbstractStarting from a non-dualistic view on embodiment this paper approaches the relationship between cognition, gesture, language, and cultural practice by analyzing the gestural construction of the cultural conceptjeitinhoin talk-in-interaction. After introducing our phenomenological view on embodiment and gesture in interaction, we give a short overview of some main studies broaching the issue of cultural matters before presenting the conceptjeitinhoas delineated in historical, sociological, and anthropological approaches. In the empirical section, we offer a fine-grained analysis of four videosequences taken from a conversation aboutjeitinhobetween two Brazilian and two German professors who have lived in Brazil for more than 20 years. We show that the gestural style of both Brazilian professors differs significantly from the gestural engagement of the German professors since they schematically embody a sinuous gesture style and construe the cultural conceptjeitinhoas aqualiumby adopting a character viewpoint while the German participants remain observers regarding their gestural performance.
Data collection methods applied in studies in the journalIntercultural Pragmatics(2004–2020): a scientometric survey and mixed corpus study
Authors: Kirner-Ludwig Monika 
Published: August 2022

AbstractMethods in Intercultural Pragmatics are inherently multifaceted and varied, given discipline’s breaching of numerous cross-disciplinary boundaries. In fact, research in Intercultural Pragmatics represents merely new ways of thinking about language and, thus, of researching interactants’ (non-)verbal behaviors: With core common ground and shared knowledge about conventionalized frames of the target language being limited, intercultural communication features a number of unique characteristics in comparison to L1 communication. This being said, the range of methods employed in data collection and analysis in Intercultural Pragmatics is not only wide, but highly heterogeneous at the same time. The present paper takes a scientometric approach to data collection methods and data types in Intercultural Pragmatics research. In order to provide an extensive diachronic survey of methods and approaches featuring in empirical studies published specifically by the journalIntercultural Pragmatics(edited by Istvan Kecskés), this study includes a self-compiled corpus of 358 papers in 17 volumes published since its launch in 2004 thru 2020. The aim is to carve out diachronic method preferences and emerging as well as declining trends in data collection methods and data types adhered to within this discipline. These are further discussed within the context of relevant state-of-the-art accounts that have specifically offered surveys of methods and methodologies pertaining to issues in data collection and data analysis in (Intercultural) Pragmatics in recent years.
Borrowed Swahili discourse-pragmatic features in Kenyan and Tanzanian Englishes
Authors: Unuabonah Foluke Olayinka , Muro Loveluck Philip 
Published: August 2022

Abstract
This study explores five Swahili discourse-pragmatic features – ati/eti, yaani, pole, sasa and sawa – which are borrowed from Swahili into Kenyan and Tanzanian Englishes, with a view to investigating their meanings, frequencies, positioning, collocational patterns, syntactic distribution and discourse-pragmatic functions. The data, which are extracted from the International Corpus of English-East Africa and the Kenyan and Tanzanian components of the corpus of Global Web-based English, are analysed quantitatively and qualitatively, from a variational and postcolonial corpus pragmatic framework. The study reveals that the Swahili discourse-pragmatic features occur more frequently in the Kenyan corpora than in the Tanzanian corpora, except in the case of sasa, which occurred with the same frequency in the online corpus. The paper identifies ati/eti as an attention marker, a quotative marker, a hearsay marker, an inferential marker, and an emotive interjection, yaani as an emphasis and elaborative marker, while pole is an attitudinal marker that expresses sympathy and sarcasm. While sasa is only an attention marker, sawa is an agreement and attention marker. The paper shows that these borrowed discourse-pragmatic features contribute to the distinctive nature of East African Englishes.
3D concept creation of permanent geodetic monitoring installations and the a priori assessment of systematic effects using Virtual Reality
Authors: Bauer Peter , Lienhart Werner 
Published: August 2022

Abstract
Logistic processes of construction sites are transferred into virtual and full 3D environments to increase the interoperability for all project partners. These digital twins are emerging for the construction process of modern building processes and are already designed to be used for the operation of the building afterwards. In structural health monitoring (SHM) the sensor installations are also designed to monitor the structure over its whole lifespan. Therefore, the embedding process and the operation of the sensor systems and the Building Information Modelling (BIM) have overlapping long-term goals. Beside these 3D software advances in civil engineering, the working environments in the field of geodesy still follow more established approaches. In many cases using only 2D CAD plans and on-site visits at the existing structure are best practice for the design of geodetic monitoring installations. This paper describes the improvement of the concept creation of permanent monitoring systems with geodetic total stations in an interactive virtual 3D environment. The simulated instruments are behaving according to their specification data and are linked with a physics engine to automatically detect common problems in a network design like obstructed line of sights, disadvantageous incidence angles at the targets or automatic aiming issues due to multiple targets in the field of view. Furthermore, the Virtual Reality (VR) technology is introduced as a user interface for a virtual 3D planning environment. The functionality of the developed VR application is tested in a real-life use case for the feasibility study of the automatic monitoring of a railway tunnel.

Abstract

Objectives
The aim of this study was to investigate the role of preoperative Monocyte-to-Lymphocyte ratio (MLR) as a potential predictor of bladder cancer (BC).

Methods
Clinical data of patients who underwent TURBT at our institution between 2017 and 2021 were collected and retrospectively analysed. MLR was obtained from preoperative blood analyses performed within 1 month from hospital admission. The association of MLR with different clinic-pathological features obtained from histological reports was further analysed. Statistical analysis was performed using the Kruskal Wallis test for non-parametric variables, assuming p<0.05 as statistically significant.

Results
510 patients were included in the study (81% males, 19% females), with a mean age of 71.66 ± 11.64 years. Mean MLR was higher in patients with any-type bladder cancer, reporting an MLR of 0.41 ± 0.11 compared to 0.38 ± 0.43 in patients without bladder cancer (p=0.043). In the subsequent comparison among low-grade and high-grade bladder cancer, MLR did not report statistically significant differences, with 0.29 ± 0.12 for low-grade BC and 0.51 ± 0.81 for high-grade BC (p=0.085)

Conclusions
Our findings reported elevated preoperative MLR should be considered a potential biomarker predicting malignancy for bladder tumours. Furthermore, research are necessary to assess its role in discerning low-grade from high-grade patients.
