Do writing performance and examination grading correlate in an EMI university setting?
Authors: Zijlmans Lidy , van Hout Roeland , van Oostendorp Marc 
Published: February 2023

Abstract
We studied German students’ academic writing skills in English at a Dutch university. Their performances are typical examples of English as a lingua franca (ELF) as these students are non-native users of English evaluated by subject lecturers who are non-native users as well. Our database is a corpus of written answers to an open examination question in the context of an EMI (English Medium Instruction) bachelor in psychology. We aimed to detect those characteristics in this specific type of discourse that may affect the comprehensibility of the students’ answers, which in turn may have consequences for their grading by the course lecturer. English language experts assigned Common European Framework of Reference (CEFR) levels and commented on grammar, use of (academic) vocabulary, and text coherence. First, we correlated the grades assigned by the course lecturer and the CEFR levels. There was no correlation. Second, we analyzed the linguistic comments. We found that academic style was poorly present in this type of text. Importantly, we found no proof of communicative blockings or obstacles related to English proficiency levels between the student writer and the lecturer reader. We conclude that informed content interpretation based on contextual appropriateness of the answers overrules grammatical and lexical non-standard characteristics and outweighs the lack of semantic coherence.
Polite impoliteness? How power, gender and language background shape request strategies in English as a Business Lingua Franca (BELF) in corporate email exchanges
Authors: Hofweber Julia , Jaworska Sylvia 
Published: February 2023

AbstractInternational business is increasingly conducted through the medium of English as a Business Lingua Franca (BELF). Yet, little is known about interactional strategies in BELF, specifically in internal written business communications. Our study turns to this hitherto less explored area and investigates one of the most important speech acts in the context of workplace communication, i.e. requests. The data under study come from a unique corpus of 398 authentic internal emails produced by the multilingual employees of an international insurance corporation. Using a combination of corpus-linguistic and discourse-analytical methods, we identify and classify request strategies formulated by BELF users with ten diverse first-language (L1) backgrounds, and assess how their choice of pragmatic strategies might be influenced by their lingua-cultural background as well as extralinguistic factors, notably the email senders’ power position within the corporate hierarchy and their gender. Across the corpus, the level of directness in request strategies was high, suggesting that most BELF users prioritised ‘getting the job done’. Yet, the directness of email senders’ request strategies was modulated by a complex interaction between lingua-cultural factors, power position and gender. The most crucial observation was that high-power employees chose more direct strategies than low-power employees, but this pattern was modulated by their lingua-cultural background and by gender.
A roster construction decision tool for MLS expansion teams
Authors: Smith Zachary J. , Bickel J. Eric 
Published: February 2023

Abstract
We present a mathematical modeling framework for roster construction of a Major League Soccer (MLS) expansion team. The model seeks to construct the best squad feasible under league salary rules, while balancing present value, potential value, and future cap flexibility. Player acquisition decisions, as well as allocation of salary, targeted allocation money (TAM), general allocation money (GAM), and designated player slots, are determined simultaneously by a mixed-integer programming model. We demonstrate the model’s functionality in constructing a hypothetical expansion roster and propose a number of extensions.
Digital Archiving Policies of Central European Journals Registered in the Directory of Open Access Journals
Authors: Marijanović Branka , Stančić Hrvoje 
Published: February 2023

Abstract
This paper examines digital archiving policies of open access (OA) electronic scholarly journals in Central Europe. The research sample consists of 1589 journals from nine Central European countries registered in the Directory of Open Access Journals (DOAJ). Results show that of the 1589 journals, 69% of them have an archiving policy. In terms of the number of indexed journals, Poland ranks first with 592 journals. Switzerland is at the forefront of digital archiving with 89% of archived journals. It was also found that Portico and national libraries are the most widely used archives, and that 19% of the preserved journals are archived in more than one archive. A preliminary analysis was also conducted to investigate the possible existence of a relationship between journal rank and digital archiving. The results show a higher number of JCR indexed titles, as well as a higher ranking, among archived journals. The paper also compares the status of archiving policies among Asian and Central European countries. The results reveal that archived journals are significantly more represented in Central European countries.
First record of the servaline morph in a serval (Leptailurus serval Schreber, 1776) in Akagera National Park, Rwanda
Authors: Bantlin Drew Arthur , Evers Emma Else Maria 
Published: February 2023

Abstract
The serval (Leptailurus serval) is a medium-sized felid that is widespread throughout Sub-Saharan Africa. We report on the first scientific record of the servaline morph in a serval in Akagera National Park, Rwanda. Though this morph has been documented in the forested ecosystems of West and Central Africa, the servaline morph has not been recorded in a predominantly savannah ecosystem. Further research into the prevalence of this morph outside of forest ecosystems and the adaptive advantage of the servaline coat pattern in servals is recommended. Our findings highlight the importance of conserving savannah ecosystems to preserve morphological diversity in a species.

Mientras en los medios de comunicación abundan noticias sobre China y el Covid-19, los estudios recientes revelan que la imagen de China en los medios de los países occidentales se deteriora durante la pandemia. De esta manera, surge la curiosidad de saber cómo los medios de América Latina, especialmente de Argentina, perfilan China. El objetivo general del presente estudio consiste en analizar la cobertura mediática argentina, tanto convencional como digital, sobre China y el Covid-19. Valiéndose del análisis de contenido sobre las noticias publicadas en Clarín e Infobae, se pretende esbozar el panorama de la imagen de China en los dos medios de comunicación argentinos y averiguar la selección de encuadres de cada medio.
La provisión de China del bien público global de la salud en México en la coyuntura de la Covid-19
Authors: Tzili-Apango Eduardo 
Published: February 2023

ResumenLa pandemia por Covid-19 ha resultado en un “mal público global” que ha afectado las dinámicas mundiales. En esta coyuntura, la República Popular de China ha surgido como un importante proveedor del bien público global de la salud, mientras que América Latina, y particularmente México, ha sido notablemente afectados por la Covid-19, especialmente en el año 2020–2021. En el presente artículo se examina la provisión china del bien público global de la salud, utilizando a México como caso de estudio. Dos preguntas de investigación guían el análisis: 1) ¿de qué manera China proveyó el bien público global de la salud en México? y ¿cuáles fueron las intenciones de la provisión? A manera de hipótesis, se argumenta que China proveyó, efectivamente, el bien público global de la salud en México por medio de insumos médicos y vacunas, aunque su principal resultado no fue un mejoramiento notable de la salud en México, sino evitar la obstaculización de las relaciones económicas y comerciales bilaterales.

Authors: Leping Huang 
Published: February 2023

Resumen
Se considera a los países de América Latina y el Caribe como una extensión natural de “la Ruta Marítima de la Seda” y participantes indispensables en la cooperación internacional de “la Franja y la Ruta”. En el siglo XXI, las relaciones económicas y comerciales entre China y la región han avanzado a pasos agigantados. Sin embargo, han salido a la luz unos problemas tales como el desequilibrio comercial y la estructura irracional de comercio y de inversión. “La Franja y la Ruta” apuesta por la conectividad global, lo que proporciona nuevas ideas y direcciones para resolver los problemas mencionados y nuevas oportunidades para el desarrollo de la cooperación económica y comercial entre China y América Latina y el Caribe. En el ámbito del comercio, es necesario optimizar la estructura comercial y promover la balanza comercial mediante la expansión de las importaciones de bienes no tradicionales de la región a China, la promoción del comercio de servicios y el desarrollo del comercio electrónico; en el ámbito de la inversión de China en la región, es necesario mejorar la estructura de la inversión directa mediante la inversión en la industria manufacturera y en la infraestructura, promover la diversificación de los objetos de la inversión mediante el apoyo financiero, y mejorar la capacidad y la voluntad de invertir de las empresas privadas y las PYME.
High-dose intravenous hydrocortisone for the treatment of hyperthyroidism: a rare precipitant of thyrotoxicosis periodic paralysis
Authors: Scheive Melanie , Patel Neha , Saeed Zeb 
Published: February 2023

Summary
Thyrotoxic periodic paralysis (TPP) is a rare complication of hyperthyroidism triggered by precipitants that increase the activity of the sodium-potassium pump in the skeletal muscle. In our case study, a previously healthy 34-year-old male presented to the emergency department with new onset thyrotoxicosis, secondary to Graves’ disease. Given the severity of his triiodothyronine (T3) thyrotoxicosis, he was admitted and started on a high dose of beta-blocker, thioamides, and intravenous hydrocortisone. On the second day of his hospitalization, he developed acute flaccid paralysis of his lower extremities. Subsequent stroke workup was negative, and his electrolytes revealed severe hypokalemia and hyperglycemia consistent with TPP. He was treated with potassium and had a complete recovery of his paralysis and hypokalemia within hours. The patient has not had any recurrence since this singular episode in the hospital. This case highlights the scenario where the treatment of hyperthyroidism with high-dose corticosteroids to reduce the conversion of thyroxine to T3 inadvertently resulted in TPP. Clinicians should be aware of this potentially rare but serious consequence of using steroids to manage hyperthyroidism.

Learning points

High-dose steroids used to treat hyperthyroidism in hospitalized patients may rarely precipitate thyrotoxic periodic paralysis (TPP) by inducing hypokalemia and hyperglycemia.

TPP should be included in the differential diagnosis for acute flaccid paralysis in hospitalized patients with hyperthyroidism.

Since TPP is associated with trans-cellular shifts in potassium instead of total body potassium depletion, conservative repletion of potassium is recommended to avoid rebound hyperkalemia.

The article studies some faunistic features of helminths of wetland birds in the ecological crisis zone in North-Western Uzbekistan. Parasites of wetland birds collected in the basin of the lower reaches of the Amu Darya during the hunting seasons of 2018–2022 were used as material for this work. 500 individuals of birds representing 39 species from 24 genera, 13 families and 9 orders were examined using the parasitological dissection method. The article discusses the distribution and ecology of the helminths in the studied groups of birds. A total of 112 helminth species were identified in the region – 28 species belong to the class Cestoda, the class Trematoda is represented by 57 species, Nematoda – 23 and Acanthocephala – 4 species. 92 species of heminths were identified in the study area for the first time. The work provides original data on the structure of the helminth fauna from 9 orders of wetland birds. Various paths of helminth transmission in the circulation of infection were specified. The researchers identified four ways parasites use to enter their definitive host: helminths penetrate the host’s body when the latter eats other organisms, intermediate or reservoir hosts of helminths, which are part of the definitive’s host’s diet; helminths enter the host as mechanical impurity to food or water; they make active efforts to penetrate their host; helminths are transmitted by the intermediate host when the latter forages on the definitive host. Most of intermediate hosts for representatives of the class Cestoda were crustaceans – inhabitants of different types of water bodies; Oligochaeta are also included here as second or reservoir hosts. The development of trematodes occurs with the participation of aquatic molluscs acting as the first intermediate host. Various species of insects, fish, amphibians, reptiles and small mammals were identified as the second hosts. Nematoda use a wider range of intermediate hosts (Oligochaeta, crustaceans, insects – aquatic and terrestrial). Fish and amphibians were registered as the second and reservoir hosts of nematodes. The food chains of individual orders of wetland birds largely determine the composition of helminths parasitising them and are the main factor in the formation of their helminth fauna. These processes undoubtedly occur in time and space under the strict control of environmental factors.

Despite long-term research on marine litter there is still insufficient knowledge about benthic organisms associated with these substrates, especially experimental studies and methodology of sampling for complex biofouling assemblages. To predict the fate of plastic in the marine environment it is necessary to know how long the macrolitter can stay in different sea matrices and what are the steps of colonisation by marine organisms. The experiments were carried out during various seasons in situ in the north-western Black Sea coastal area. Three new types of the experimental constructions intended for different durations of exposure (1–10 months) were designed. This article is the first to present the methodology and the results of complex experiments investigating marine fouling (from microalgae to meio- and macrofauna) on plastic surfaces. Overall, 28 genera of microalgae, 13 major groups of meiobenthos and 36 species of macrofauna were found on plastic during the experiments. The microalgae fouling was mainly formed by representatives of genus Cocconeis. The species composition of microalgae was common for the research area. The average density and biomass of meiobenthos were the greatest on I construction type after 8 months of exposure. In the total macrozoobenthos biomass and density of Bivalvia and Crustacea dominated, respectively. The obtained results on the interaction between fouling organisms and plastic materials in the marine environment form an important contribution to the understanding of the "good ecological status" of the sea. Additional studies based on the tested methodology could be used as a component of ecological monitoring during development and implementation of the approaches of the Marine Strategy (descriptor 10).

Published: February 2023

AbstractPregabalin is a gabapentinoid approved for the treatment of general anxiety disorder, neuropathic pain and as adjunctive therapy for focal seizures in patients with epilepsy. In addition, there are a number of conditions for which pregabalin is prescribed off-label. Along with the widespread use there are a significant number of reports describing the misuse of pregabalin over the last decade. Over time, it became clear that pregabalin should become part of routine testing in toxicology laboratories. The aim of this paper was to present validation of a LC-MS/MS method for the quantification of pregabalin in plasma of acutely poisoned patients. Simple sample preparation step and rapid chromatographic separation shortened the overall analysis time, which was the goal of method development. The presence of pregabalin was confirmed with three ion transitions, ensuring high selectivity of the validated method. The statistical data obtained showed good precision and accuracy over a wide concentration range. No endogenous or other interference was detected, and there was no matrix effect influence with this method. The LC-MS/MS method was applied to quantify pregabalin in plasma samples of patients admitted to the emergency department due to a possible acute pregabalin overdose. Different concentrations were found, and we report, to the best of our knowledge, the highest plasma concentration of pregabalin in the plasma of a patient with acute poisoning. In conclusion, we developed a fast and simple LC-MS/MS method for reliable determination of pregabalin and demonstrated the developed method was suitable for routine use in clinical toxicology setting.

Application of Nucleic Acid-Based Strategies to Detect Infectious Pathogens in Orthopaedic Implant-Related Infection
Authors: McClure Emily Ann , Werth Paul , Ross Benjamin , Gitajn Ida Leah 
Published: February 2023

➤ Implant-associated infection in orthopaedic surgery remains an enormous and largely unsolved clinical problem with a high rate of persistent or recurrent infection. This may be due, at least in part, to the potential for underdiagnosis by traditional microbial culture or the potential for culture to incompletely identify the microbial species present.➤ Nucleic acid-based diagnostic techniques, focused on using the diagnostic information contained in DNA or RNA to identify microbial species, have been developing rapidly and have garnered escalating interest for both clinical and research applications.➤ Commonly applied techniques include end-point polymerase chain reaction (PCR), quantitative PCR, Sanger sequencing, and next-generation sequencing. Understanding the specific strengths and weaknesses of each technique is critical to understanding their utility, applying the correct assessment strategy, and critically understanding and interpreting research.➤ The best practices for interpreting nucleic acid-based diagnostic techniques include considering positive and negative controls, reads per sample, detection thresholds (for differentiating contaminants from positive results), and the primer set or targeted regions.
