Authors: Oladunjoye Adeolu Funso , Li Elijah , Aneni Kammarauche , Onigu-Otite Edore 
Published: October 2023

Background
Suicide is among the top three causes of adolescent mortality. There is a scarcity of research examining cannabis use and suicidal behavior in adolescents.

Objectives
To determine the association between cannabis use disorder (CUD) and suicide attempt/self-harm in a hospitalized sample of adolescents.

Methods
We conducted a cross-sectional observation study using data from the Nationwide Inpatient Sample collected over four years from January 1, 2016, through December 31, 2019. We included adolescents aged 10–19 hospitalized during the above period (N = 807,105). The primary outcome was suicide attempt/self-harm and the main predictor was CUD. The International Classification of Diseases Tenth Revision (ICD 10) diagnostic codes was used to identify a diagnosis of CUD, suicide attempt/self-harm, and other diagnoses included in the analyses. Adolescents diagnosed with CUD (n = 53,751) were compared to adolescents without CUD (n = 753,354). Univariate and multivariate logistic regressions were conducted to determine the association between CUD and suicide attempts/self-harm.

Results
807,105 adolescent hospitalizations were analyzed, of which 6.9% had CUD. Adolescents with CUD were more likely to be older (17 years vs. 15 years), female (52% vs. 48%), have depression (44% vs. 17%), anxiety (32% vs. 13%), an eating disorder (1.9% vs. 1.2%), ADHD (16.3% vs. 9.1%), Conduct Disorder (4.1% vs. 1.3%), Alcohol Use Disorder (11.9% vs. 0.8%), Nicotine Use Disorder (31.1% vs. 4.1%), Cocaine Use Disorder (5.4% vs. 0.2%), Stimulant Use Disorder (0.8% vs. 0.4%) and report suicide attempts/self-harm (2.8% vs. 0.9%) [all ps<0.001]. After adjusting for potential confounders, CUD was associated with a higher risk of suicide attempts/self-harm (OR = 1.4, 95% CI 1.3–1.6, p <0.001).
Post-hoc analyses showed the presence of depression moderated the association between CUD and suicide attempts/self-harm in that adolescents with CUD and depression had 2.4 times the odds of suicide attempt/self-harm compared to those with CUD but no depression after controlling for potential confounders (p<0.001).

Conclusions
Our study provides evidence for the association between CUD and suicide risk among hospitalized adolescents and underscores the importance of recognizing and addressing co-occurring mental and substance use disorders along with CUD to mitigate suicide risk. Identifying high-risk adolescents in inpatient settings provides an opportunity for intervention.
On the bond polytope
Authors: Chimani Markus , Juhnke-Kubitzke Martina , Nover Alexander 
Published: October 2023

Abstract
While the maximum cut problem and its corresponding polytope has received a lot of attention inliterature, comparably little is known about the natural closely related variant maximum bond. Here, given a graph G = (V, E), we ask for a maximum cut δ(S) ⊆ E with S ⊆ V under the restriction that both G[S] as well as G[V \ S] are connected. Observe that both the maximum cut and the maximum bond can be seen as inverse problems to the traditional minimum cut, as there, the connectivity arises naturally in optimal solutions.
The bond polytope is the convex hull of all incidence vectors of bonds. Similar to the connection of the corresponding optimization problems, the bond polytope is closely related to the cut polytope. While the latter has been intensively studied, there are no results on bond polytopes. We start a structural study of the latter, which additionally allows us to deduce algorithmic consequences.
We investigate the relation between cut- and bond polytopes and the additional intricacies that arise when requiring connectivity in the solutions. We study the effect of graph modifications on bond polytopes and their facets, akin to what has been spearheaded for cut polytopes by Barahona, Grötschel and Mahjoub [4; 3] and Deza and Laurant [17; 15; 16]. Moreover, we study facet-defining inequalities arising from edges and cycles for bond polytopes. In particular, these yield a complete linear description of bond polytopes of cycles and 3-connected planar (K
5 − e)-minor free graphs. Finally, we present a reduction of the maximum bond problem on arbitrary graphs to the maximum bond problem on 3-connected graphs. This yields a linear time algorithm for maximum bond on (K
5 − e)-minor free graphs.

Published: October 2023

AbstractA touch-evoked response of zebrafish larvae provides information on the mechanism of the gene functional expressions. Recently, an automated system has been developed for precise and repeated touch-response experimentation with minor human intervention. To quantify the collected data, we propose a fully automated multi-larvae touch-response behavior inspection pipeline based on larva tracking and segmentation. Experimental data with different treatments is analyzed by using the proposed inspection platform for demonstration, and the result proves that this platform can generate comparable touch-response behavior inspection readouts efficiently and automatically. The initial results were published in 31. Workshop Computational Intelligence, and this paper summarizes and extends the main work of the respective article.
Training citizens as users of languages and digital technology. Real-world tasks to tame the digital wilds
Authors: Jeanneau Catherine , Ollivier Christian 
Published: October 2023

Abstract
Developing digital literacy and, more recently, digital citizenship is one of the objectives promoted by the major international organisations involved in the education sector. However, in order to integrate digital citizenship into education a thorough understanding of the intended outcomes is required. This is why a meta-analysis of recent texts was carried out. The paper presents the result of this literature review consisting in a structured compilation of all the defining elements that constitute our profile of citizens as users of languages and digital technology. We suggest a way in which to integrate digital citizenship education into language education and describe the socio-interactional pedagogical approach adopted in the context of two projects, elang citizen and Lingu@num. This approach is based on the execution of authentic tasks, referred to as real-world tasks. We also present the results of a questionnaire carried out by teachers who explored these tasks and reported that by engaging in them, language learners can experience authentic communication and action as citizens in the “digital wilds” beyond the classroom walls and develop both their language skills and their digital citizenship.
Attitudes to Spanish language variation. A study on Portuguese students of Spanish as a Foreign Language
Authors: Santos Rovira José María 
Published: October 2023

Abstract
Drawing on data collected via a web-based survey, this study investigates the attitudes of SFL (Spanish as a Foreign Language) learners in Portugal towards four Spanish varieties. A verbal guise experiment was designed to collect students’ perceptions of language variation. The sample comprised 196 undergraduate students from the School of Arts and Humanities of the University of Lisbon (Portugal). The results show that Portuguese students of SFL have a clear preference for the Castilian variety, as it obtained the highest rates in all domains (power, personal qualities, and status). Unexpectedly, factors such as participants’ age or sex did not influence the answers given.
A critical literacy class: beyond English learning and teaching in Higher Education
Authors: Derince Zeynep Mine 
Published: October 2023

Abstract
This article aims at analyzing the introduction of Critical Literacy as a transformative teaching approach in an English language teaching setting at tertiary level in Turkey. Applying a Freirian understanding of education, the method sought to tap the sociopolitical consciousness brought into the classroom by students and teachers and co-construct knowledge collectively while contributing to identity formation and social transformation. Both learners and teachers were encouraged to relate the curriculum to their own diverse experiences and to analyze broader social issues that are relevant to their lives and to wider contexts. Consequently, such issues as curriculum, language teaching and learning environment, materials and language policies were scrutinized from a critical perspective as part of the language learning and teaching process taking place in the classroom. The findings of this research provide significant insights for language learning and teaching praxis and show how Critical Literacy as a teaching method can contribute to the creation of more meaningful and supportive learning environments in classrooms and suggest empowering interactions among the actors involved.
From face-to-face tuition to online classes: ‘Re-styling’ a course of English for academic purposes
Authors: Scott-Monkhouse Anila R. 
Published: October 2023

Abstract
With the outbreak of the COVID-19 pandemic and the ensuing total lockdown in 2020, the EAP course for STEM doctoral students at Parma University (Italy) was suddenly forced to online delivery, like many courses in academic institutions worldwide. Confined at home and with no previous experience in remote teaching, the teacher had to redesign the course and rethink strategies and techniques in a matter of days and with little material at hand. The aim was to maintain the interactivity of the face-to-face course and consolidate the group dynamics of a course that had yet to start. As online teaching took centre stage, the teacher and students alike were confronted with didactic issues stemming from the restyling of a traditionally highly interactive course based on face-to-face tuition, and technical problems, which added to the emotional and psychological factors related to an unknown, unexpected situation. In addition to soft skills, students from different academic backgrounds needed to develop productive rather than receptive language skills, so activities focused mainly on collaborative tasks to develop writing and speaking modes but did not concentrate on academic language only. This paper shares insights into the experience of being ‘thrown in at the deep end’, and attempts to highlight the elements which contributed to its overall positive outcome, the strong social connotation it came to bear, the development of class dynamics, and the learning points that emerged. It also hopes to provide some practical suggestions which can add to the creative solutions found by (language) teachers globally.
Testing English for Medical Purposes: the effects of traditional and distance education on learning outcomes
Authors: Barnau Anna 
Published: October 2023

Abstract
The COVID-19 pandemic brought about new cultural and social phenomena that changed social interaction and communication. In this new situation, teachers teaching English for Medical Purposes (EMP) at the Jessenius Faculty of Medicine of Comenius University in Martin (JFM) had to adapt the courses to the educational needs of the students. This study explores the effects of traditional and distance education on learning outcomes in advanced English learners during three academic years. The sample consisted of 346 students. Three groups (G1, G2, G3) of first-year students attended online as well as face-to-face English courses and took EMP exams at the end of each summer semester. The test results were compared and evaluated. The methods of EMP teaching and testing were different in each group. G1 attended asynchronous online classes, G2 participated in synchronous online classes conducted in real-time, and finally, G3 participated in traditional classes. G1, G2 took online tests, and G3 took a pen-and-paper test. The questionnaire revealed that students appreciated the self-organization of study during online classes, but most criticized the lack of face-to-face communication, the classroom atmosphere, and technical difficulties during online teaching. Students participating in traditional classes missed their own time management and appreciated discussion in the classroom as well as teachers’ feedback on EMP performance.
Using corpora in teaching vocabulary to advanced EFL learners in a higher education context
Authors: Can Hümeyra 
Published: October 2023

Abstract
This study focuses on the development of lexical competence of tertiary level EFL learners who have reached C1 level according to CEFR during their course of study, but who still have difficulty in recognizing and producing academic words in terms of their correct and appropriate use in various contexts. Following a data-driven learning (DDL) approach within an action research paradigm, this study aims to discover whether corpus investigation makes a difference in students’ vocabulary knowledge and how they react to corpus data in learning vocabulary. To this end, the study was carried out in a listening/speaking course of two C1 level classes in an EFL classroom at an English preparatory school in Higher Education. In one of the classes, conventional lesson materials, and in the other, corpus-based lesson materials were used to teach the selected vocabulary items. The effect of corpus-based lesson materials on vocabulary learning was examined in relation to conventional materials. The data obtained from pre and post-tests showed that although there was a significant increase in students’ scores from pre-test to post-test, corpus use made statistically no significant difference in their scores as compared to the conventional method that had been adopted during the regular course of study based on the contextual guesswork involved in the coursebook. Students’ reactions throughout the implementation of corpus-based materials and the feedback sessions held with the students, shed light on the results and suggested some pedagogical guidelines for using corpora in teaching L2 vocabulary.
Model United Nations: a thematic analysis of Japanese EFL students’ reflections on intercultural communicative competence
Authors: Nfor Samuel 
Published: October 2023

Abstract
This study investigated Model United Nations (Model UN), a simulation of the United Nations that is adapted for academic purposes and includes elements of discussion, negotiation, presentation, and engagement with global issues and international affairs. When students participate in Model UN, they are referred to as country delegates and represent different countries on different committees. As delegates, they join in discussions on global issues related to such topics as world conflict, international security, human rights, and education. In Model UN, student participants from diverse linguistic and cultural backgrounds, collaborate and interact in a common language (English) spoken differently among participants to deepen their understanding of current world issues. By so doing, they reflect on their intercultural communicative competence summarized as the ability to interact with people from another country and culture in a foreign language. Following a Model UN semester course at a Japanese university and a Model UN conference held in Japan, interview sessions with Model UN student participants were moderated and recorded to understand their learning attitudes and experiences of studying in the Model UN context. The interview data were used to generate themes for thematic analysis. The study concluded that Japanese Model UN student participants’ interactions with other learners of English from different cultural backgrounds allowed them to reflect on their intercultural communicative competence and, thus, be able to develop tolerance towards language-related misunderstandings.
University English-medium instruction in Türkiye – what instructors say
Authors: Kurt Yavuz , Bayyurt Yasemin 
Published: October 2023

Abstract
The rise of English-medium instruction (EMI) and the increasing number of international students in Turkish universities call for a change in the language support programs that prepare students for EMI. English as a lingua franca (ELF) is a promising perspective to achieve a more linguistically and culturally inclusive pedagogy. This paper reports the views of 10 English language instructors who took a teacher training course on ELF and experimented with ELF-aware teaching with several lessons in the classroom. Semi-structured interviews were conducted with the instructors to explore how they conceptualized the relationship between ELF and their teaching context, and how they evaluated their teaching experiences. Results reveal that when preparing students for EMI, instructors saw ELF as a useful frame of reference that promoted students’ confidence, motivation, and critical thinking. Instructors’ teaching preferences were shaped by the curriculum they were supposed to follow, the materials at their disposal, and the characteristics of their learners. Findings highlight the need to equip students for the variability in the English language, and become more confident with their linguistic skills as multilingual speakers, as well as engage in critical thinking about English and its use in their context.
Wer die worheit gerne mynn / Und sich güter dinge versynn, / Der müsz der besten einre sin
Authors: Meyer Tim 
Published: October 2023

Abstract

Lutwin’s late 13th century account of the lives and deaths of the protoplasts and their first descendants, ‘Eva und Adam’, employs traits and literary techniques usually associated with vernacular courtly literature to convey its religious message to an audience of German speaking nobility. Such techniques include the amplification of the source material by adding newly invented sequences to the narrative’s plot as well as a highly self-conscious narrator, reflecting on his role as a mediator of divine revelations while, at the same time, openly exhibiting his ability to orchestrate the events and characters within his narrative. For decades, the scientific community has been split over the question whether these features may present evidence that contemporaries might have viewed the majority of courtly epics and romance as purely fictional. However, considering the religious nature of Lutwin’s themes and statements, it seems unlikely to assume that a medieval audience had to actively suspend their disbelief in order to accept courtly adaptations of biblical stories. Applying the modern dichotomy between factuality and fictionality therefore leads us to regard Lutwin’s ‘Eva und Adam’ as a paradoxical text riddled with inconsistencies. The concept of ‘fideales Erzählen’, recently introduced by Elke Koch, provides an alternative and potentially more adequate means of describing the historical modes of conceiving and perceiving premodern religious literature. Accordingly, instead of empirical verifiability being the main criteria in determining the status of factual or fictional texts respectively, faith, divine inspiration and adherence to common orthodoxy could, in the notion of a medieval audience, enable authors to present truthful insights into otherwise unattainable religious truths. Based on Koch’s deliberations, this paper re-evaluates several aspects of Lutwin’s ‘Eva und Adam’ – most notably the conception of its narrator – which in the past would have been considered as traits of fictional literature. It can be shown that, although Lutwin acts as a conscious arranger of his narration, his account’s proclaimed verisimilitude remains unchallenged.
Spectroscopy electrochemical impedance characterization of membranes electrode assemblies for PEM electrolyzers

Published: October 2023

Abstract
Hydrogen is projected as a key energy vector to achieve aspiring global decarbonization goals mainly for those sectors where greenhouse gas emissions are highly challenging to reduce. Therefore, green hydrogen production using water PEM electrolysis has become the aim of numerous recent studies. One of the crucial challenges for improving hydrogen production is reaching a deep knowledge of the role of anodes electrocatalysts. In this investigation we studied and modeled the effect of different anode electrocatalysts and solid electrolyte’s configurations in a single-cell PEM electrolyzer performance, using EIS. We assembled and tested PEM electrolysis MEAs with two different configurations. MEA-1 comprises in catalyst-coated membrane (MEA)-type with a geometric area of 25 cm2 containing Nafion™ 115, 3.0 mg cm−2 IrRuOx as the anode, and 3.0 mg cm−2 PtB for the cathode. MEA-2 involves catalyst-coated membrane (MEA)-type with a geometric area of 25 cm2 containing Nafion™ 117, and 3.0 mg cm−2 PtB both for the anode and cathode. Sintered Ti plates were used as gas diffusion layers. After hydration and activation steps at room temperature, the polarization curve was performed. Hysteresis curves were achieved to provide information on thermal equilibrium during the measurements. The oxygen and hydrogen production rate were measured and compared to theoretical values. Experiments were carried out at 20  and 40 °C. EIS measurements were performed at different points of the polarization curve, sweeping a frequency range between 10 kHz and 10 mHz, with an amplitude of 5 mV and taking 10 points per decade. To avoid electrocatalysts area effects in charge transfer reaction, time constants were calculated. It can be clearly observed the trend of resistances and overpotentials according to different process control. Low onset potential for oxygen evolution reaction depicts for MEA-1 means that there will be less power consumption to achieve the same efficiency or same amount of gas generation rate compared to high onset potential case depicted for MEA-2. Although different membrane thicknesses would result in different electrochemical performances due to the change in the ionic resistance, for the thickness studied we did not observe a change in the ionic resistance. The experimental results show an increase in efficiency with temperature, reflected in higher currents for a given potential and lower time constants resulting in the EIS runs.
The Qurʾān and the Putative pre-Islamic Practice of Female Infanticide
Authors: Lindstedt Ilkka 
Published: October 2023

AbstractIn this article, I take issue with one alleged characteristic of pre-Islamic Arabia: namely, the notion that the Arabians frequently, and disturbingly, practiced female infanticide by burying their daughters alive. This is what the Islamic-era religious scholars inferred on the basis of two qurʾānic passages (Q Naḥl 16:57–59 and al-Takwīr 81:8–9). However, I will argue that the classical Muslim scholars’ interpretation of these verses is highly tendentious. By analyzing the specific qurʾānic passages and comparing the crucial wordal-mawʾūdah(Q 81:8), usually translated as “the daughter buried alive,” with early Arabic poetry, I conclude that the conventional understanding of it is unlikely.
