Prevalence and determinants of hyperemesis gravidarum among pregnant women in Ethiopia: A systematic review and meta-analysis
Authors: Beyene Girma Alemayehu , Ayele Nitsuh D. , Kasahun Abebaw Wasie 
Published: December 2024

Background
Studies focusing on the occurrence and correlates of hyperemesis gravidarum in Ethiopia have reported varied values in different regions of the country. Additionally, there is no systematic review and meta-analysis summarizing the prevalence of hyperemesis gravidarum and its determinants in Ethiopia. Hence, this systematic review and meta-analysis aimed to estimate the overall prevalence of hyperemesis gravidarum and explore its determinants in Ethiopia.

Methods
Cross-sectional or case-control studies conducted in Ethiopia, written in English, and reporting the prevalence or the determinant of hyperemesis gravidarum among pregnant women were included in the review. International databases (PubMed, Scopus, Cochrane Library, Google Scholar, Science Direct, African Journal Online, Directory of Open Access Journal, and African Index Medicus) and Ethiopian university repositories (Jimma, Addis Ababa, Haramaya, Hawassa, and Gondar Universities) were searched from September 4–15, 2023, to identify articles published on the topic. The pooled prevalence of hyperemesis gravidarum with a 95% confidence interval was presented using the forest plots. The heterogeneity of the studies was checked by I2 with its corresponding p-values and the Galbraith plot. Subgroup analysis and meta-regression were performed to identify sources of heterogeneity. Funnel plot, Egger, and Begg’s tests were used to assess publication bias.

Results
A total of 11 articles with a 3510-sample size were included in this systematic review and meta-analysis. The pooled prevalence of hyperemesis gravidarum among pregnant women in Ethiopia was 7.12% with a 95% CI (4.09–10.15) and a high level of heterogeneity (I2 = 86.5%, p<0.001). Subgroup analyses revealed the overall prevalence of hyperemesis gravidarum was highest in the Amhara region with 11.30%, 95% CI (8.20–14.40), and lowest in Oromia with 3.40%, 95% CI (1.94–4.85). Having a previous history of hyperemesis gravidarum (POR = 3.828, 95% CI: 1.673–5.983), being in the first trimester of pregnancy (POR = 8.476, 95% CI: 5.047–11.905), and Helicobacter pylori infection (POR = 3.924, 95% CI: 2.027–5.821) were found to be significantly associated with hyperemesis gravidarum in Ethiopia.

Conclusion
The prevalence of hyperemesis gravidarum among pregnant women in Ethiopia is high. Targeting pregnant women in the first trimester, with a previous history of hyperemesis gravidarum, and those with Helicobacter pylori infection during prenatal counseling on how to manage and reduce hyperemesis gravidarum is very helpful to avert related complications.

Registration
The review was registered in the International Prospective Register of Systematic Reviews (PROSPERO) with the registration number “CRD42023461808”, on September 19, 2023.

Electricity from saccharide-based galvanic cell
Authors: Mophan Nattinee , Poonsawat Thinnaphat , Chumkaeo Peerapong , Somsook Ekasith 
Published: December 2024

Abstract
Here we report a practical laboratory that first-year undergraduate students can do in a general chemistry framework to explore both electrochemistry and transition metal chemistry. These laboratory activities focus on the use of saccharides and specifically starch as possible sustainable sources of energy by experimenting with the redox reactions that occur between vanadate ions and different saccharides. Students undergo hands-on experiments in order to see color changes that indicate electron transfer and link to real-world applications of these concepts in energy conversion. To reduce dependency on foreign resources and the economic risks of foreign energy product prices, the experiments employed agricultural products to generate electricity. Through the application of “Sufficiency Economy” philosophy, this work provides students with lessons in sustainable practice and the fundamentals of electrochemistry, which are essential for addressing today’s global challenges.

Accouchons des idées, pas des articles: politiser la proposition de Wolfgang Klein pour repenser le travail scientifique [Langage et Société]
Authors: Greco Luca 
Published: December 2024

Résumé
Construit comme une réponse au texte de Wolfgang Klein, cet article se propose de pousser aux extrêmes conséquences le raisonnement du linguiste allemand pour enfin le politiser. En m’appuyant sur un corpus théorique issu de l’Autonomie ouvrière italienne des années 70, du féminisme matérialiste et de la critique portée par Marcel Duchamp aux modes de production capitaliste dans l’art contemporain, je propose dans ce texte une réflexion autour des modes de production scientifique à l’ère du capitalisme néolibéral. Par ce que j’appelle une grève de publications et l’ouverture conséquente d’autres espaces temps possibles proches des performances artistiques, je propose de repenser les pratiques de travail scientifique par la déconstruction de l’articulation entre les pratiques de publication et l’identité du/de la chercheur.e.
Dromm und die verlorene Balance [The Mouth: Critical Studies on Language, Culture and Society]
Authors: Storch Anne 
Published: December 2024

Abstract
Dromm ist ein Linguist, der die akademische Welt und damit die binäre Ordnung von submission und review verlassen hat. Er arbeitet meist als Experte, der ausgewählte cold cases löst, ist aber einem größeren Publikum vor allem durch seine Unterschrift in einem Requisiten-Gästebuch in der italienischen Serie Rocco Schiavone bekannt (Brignone 2019 [2016], Staffel 1,3: Sturz in den Tod, 32:02.). Er hat sowohl zur Linguistik der Nacht (Nassenstein & Storch 2022, Nachtlinguistik) als auch zum Problem der Sprache als Teil der Allmende (Storch 2024, Im Ziegelplattengrab) beigetragen. In diesem Beitrag legt er sein Verständnis der akademischen Linguistik als einer konstruierten Welt der Knappheit dar, in der viele Praktiken des Ausschlusses und der Marginalisierung unreflektiert und unangefochten bleiben.
What is the place of African languages in knowledge production? [South African Journal of African Languages]
Authors: Ncube Gibson 
Published: December 2024

Abstract
Despite their vast potential, African languages are often marginalised in the knowledge production ecosystem. This article explores the multifaceted roles African languages could play not just in shaping and preserving indigenous knowledge systems and fostering cultural identities but also in being languages of science and communication of science. By examining the complex dynamics of the hierarchisation of languages within the knowledge production system, this article underscores the importance of decolonising knowledge production processes to amplify the vast untapped potential of African languages as languages of science and of knowledge production. Furthermore, the article discusses the potential of African languages as vehicles for innovation and inclusive development, advocating for concerted efforts to promote linguistic diversity and equity in scholarly discourse. The article contends that the underrepresentation of African languages has inadvertently necessitated more resources to be channelled towards increased publication in these languages.
Recognising the human in humanities [Australian Review of Applied Linguistics]
Authors: Oliver Rhonda , Dovchin Sender 
Published: December 2024

Abstract
In this essay we reflect upon Wolfgang Klein’s 1989 paper Schreiben oder Lesen, aber nicht beides, oder: Vorschlag zur Wiedereinführung der Keilschrift mittels Hammer und Meißel (Zeitschrift für Literaturwissenschaft und Linguistik 74. 116–119) about the exponential development of knowledge and the imbalance between the production and reception of this. Whilst appreciating the sentiment, we argue against what seems to be his underestimation of the contribution of humanities. Klein suggests those in our field are content because unlike natural scientists, we “do not harm”: We contend we do much more – supporting and enhancing the lives of humankind. When addressing the question of “why do we do what we do?”, we answer by saying humanities and specifically applied linguistic researchers make a difference. We strive to understand the linguistic landscape, and to heighten awareness and understanding about culture, language, language learning and communication. Those working in the field advocate for and support those who are marginalised and lack agency, giving voice to those who are often silenced.
The economic reterritorialization of academic publishing and the politics of reading [Journal of Sociolinguistics]
Authors: Pietikäinen Sari , Zavala Virginia 
Published: December 2024

Abstract
Using Klein’s observation of almost 35 years ago of the disturbed balance between production and reception of academic knowledge as a starting point, we reflect on some of the tensions related to current reading practices in academic publishing. Specifically, we discuss two tensions that we encounter and try to resolve in our role as editors: 1) the tension between standardization and creativity, and 2) the tension between monologue and dialogue. Throughout, we also discuss a third more general tension, namely the gap between academic values of knowledge production embedded in the collegial work for scientific publications, and the profit driven publishing industry.
Exploring pre-service foreign language teachers’ intention to adopt technology: an investigation from the perspective of Situated Expectancy-Value Theory
Authors: Li Siying 
Published: December 2024

Abstract
The intention of pre-service foreign language teachers to adopt technology (PIAT) reflects their willingness to integrate educational technology tools into their teaching practices, which is essential for the digital transformation of language education and the professional development of teacher candidates. Drawing upon the Situated Expectancy-Value Theory, this study utilizes a structural equation model to analyze the factors influencing the intention of pre-service foreign language teachers to adopt technology. The results reveal that: (1) four motivational factors (i.e., self-efficacy, perceived enjoyment, perceived importance, and perceived usefulness) significantly predict PIAT, while perceived anxiety negatively correlates with, but does not significantly predict PIAT; (2) mindset significantly impacts perceived enjoyment, perceived importance, perceived usefulness, and perceived anxiety; (3) social influence exerts a significant influence on self-efficacy and mindset. The study concludes with implications for enhancing the digital literacy of foreign language teacher candidates.
Enhancing advanced vocabulary in EFL writing: an AI-assisted intervention for English studies students in Poland
Authors: Pitura Joanna 
Published: December 2024

Abstract
Effective use of advanced vocabulary is crucial for higher-level English language learners, particularly as they progress towards C1 proficiency according to the Common European Framework of Reference for Languages (CEFR). However, incorporating sufficiently sophisticated vocabulary in writing remains challenging for many learners. This quasi-experimental study investigated the effectiveness of an AI-assisted intervention designed to enhance awareness and use of advanced vocabulary among B2 level first-year English Studies students in Poland (n = 71). The intervention, integrated into regular coursework over five sessions, included exposure to advanced vocabulary through reading, explicit instruction on word proficiency levels, and opportunities for vocabulary use in writing. Data were collected through summary writing and word recognition tasks. The CEFR checker, an AI-based text analyser, was employed to identify C1+ and B2 level vocabulary in students’ writing. Results revealed modest but noticeable improvements in both the use and recognition of C1+ and B2 level vocabulary over time. The study also found changing correlations between vocabulary use and recognition across sessions, particularly for C1+ words. These findings highlight the potential of AI-assisted instruction in enhancing advanced vocabulary among higher proficiency EFL learners. The study contributes to the growing body of CALL literature on AI-assisted L2 instruction and opens avenues for further research on new pedagogical approaches to facilitate advanced vocabulary development in EFL writing.
Thinking the Pure and Empty Form of Dead Time. Individuation and Creation of Thinking in Gilles Deleuze’s Philosophy of Time
Authors: Eftestøl Torbjørn 
Published: December 2024

Abstract
In his account of the individuation and creation of thinking in Difference and Repetition Gilles Deleuze claims that there belongs “an experience of death.” What does this mean and imply for an attempt to come to terms with Deleuze’s transcendental empiricism? The following article presents a reading that explores this question, arguing that Deleuze’s account of what it means to think has two aspects that must be understood in relation to each other. On the one hand, Deleuze’s ontology of intensive difference involves an image of human individuation grounded upon a “death present in the living.” On the other hand, Deleuze writes that in the creation of “thinking in thought” there is an experience of death. Understanding the relation between the individuating aspect of death – as the emergence of the pure and empty form of time as the basis for representational thinking and judgement – and the experience of this individuating factor in the creation of thinking in thought, Deleuze’s claim can be made sense of and its centrality in his system clarified. When death as an individuating factor becomes experience, thinking is transmuted from dead representation to intensive life, and transcendental empiricism is operationalized.
Effect of incorporating ultrafine palm oil fuel ash on the resistance to corrosion of steel bars embedded in high-strength green concrete
Authors: Magbool Hassan M. , Zeyad Abdullah M. , Aksaraei Aliakbar Mahmoudi Kouch , Johari Megat Azmi Megat 
Published: December 2024

Abstract
Durability degradation in reinforced concrete (RC) constructions is commonly attributed to the steel reinforcement corrosion caused by chloride. The utilization of supplemental cementitious resources, such as waste materials from industrial and agricultural sectors, typically improves the impermeability and strengthens concrete resistance to corrosion, sulfate, and acid attacks. Therefore, the prevention of steel reinforcement corrosion is greatly important in resolving challenges related to the durability and stability of RC structures, particularly when utilizing agriculture waste materials. This approach also serves as a solution for waste disposal. The aim of this study is to investigate the corrosion-resistant characteristics of high-strength concrete that contains ultrafine palm oil fuel ash (U-POFA) as a partial replacement for cement. Four high-strength green concrete (HSGC) mixes were investigated in this study with a partial replacement of ordinary Portland cement (OPC) by U-POFA at 0, 20, 40, and 60% by mass. The aim of this study is to analyze the workability, strength activity index (SAI), compressive strength, rapid chloride permeability, linear polarization resistance (LPR) by different measurement methods, and four-probe resistivity measurement by electrical resistivity measurement method of over a curing period of 7, 28, 60, and 90 days. The use of U-POFA in the different mixes results in improved workability, SAI, compression strength, and chloride penetration resistance compared with the zero-POFA mix. It is clear from the study results that adding U-POFA as a partial replacement for OPC improved the corrosion resistance of HSGC mixtures. Thus, the incorporation of U-POFA 60% succeeded in reducing the chloride ion penetration by 80% and the LPR by 93% at the test age of 90 days, compared to the reference mixture.

Published: December 2024

SummaryBladder paragangliomas are rare extra-adrenal urological tumors that account for around 0.05% of bladder cancers. Their diagnosis is often delayed because of the rarity of these tumors. There is a risk of an intraoperative hypertensive crisis if not diagnosed or identified before surgical removal. We describe a case of a 36-year-old lady presented with a 10-year history of post-micturition palpitations and headaches. Her biochemical workup showed raised urinary normetanephrine levels and imaging showed a 123I MIBG-avid bladder mass compatible with bladder paraganglioma, although interestingly almost no tracer was picked up in 68Ga DOTATATE imaging. She was started on phenoxybenzamine to control her blood pressure prior to surgery. She underwent a successful robotic partial cystectomy with no complications. After surgery, she remained symptom-free. Bladder paragangliomas are rare neuroendocrine tumors of the bladder, which need to be diagnosed and managed effectively to avoid intraoperative and long-term complications.Learning pointsIt is important for patients with a bladder lesion to have a comprehensive differential assessment and biochemical and radiological investigations including functional imaging.Multiple imaging modalities along with what is available are useful in the assessment of bladder paraganglioma.The key role of the multidisciplinary team is to plan treatment in the perioperative period for minimizing risk, especially in situations where optimal management is actively debated.
Дозові залежності фосфоресценції та релаксації струму провідності в кристалах ZnSe

Published: December 2024

При температурі збудження в процесах фосфоресценції та релаксації струму провідності приймають участь як мінімум три типи пасток (мілка, фосфоресцентна та глибока). Тому необхідно використовувати багатоцентрову модель кристалофосфору, для якої одержані теоретичні залежності інтенсивності фосфоресценції і релаксації струму провідності. Ці залежності враховують процеси повторної локалізації носіїв заряду на усі пастки. Рівень заповнення різних пасток залежить від інтенсивності збудження, а не тільки від загальної дози опромінення. Усі експериментальні залежності інтенсивності фосфоресценції і релаксації струму провідності для кристалів ZnSe (дози рентгенівського опромінення змінювались в межах чотирьох порядків) добре описуються одержаними теоретичними залежностями. Одержані одночасно дозові залежності фосфоресценції і релаксації струму провідності в різних зразках підтверджують, що час спустошення кожного типу пасток визначається не тільки імовірністю термічної делокалізації, а й співвідношенням концентрації цієї пастки до загальної концентрації більш глибоких пасток.
