L2 grammar‐for‐interaction: Functions of “and”‐prefaced turns in L2 students’ collaborative talk
Authors: Tůma František , Kääntä Leila , Jakonen Teppo 
Published: November 2023

AbstractThis article examines how second language (L2) interactional competence is manifested in students’ use of “and”‐prefaced turns when doing meaning‐focused oral tasks in pairs and small groups. Drawing on video recordings from English‐as‐a‐foreign‐language upper‐secondary classes recorded in Czechia and Finland, 86 sequences involving “and”‐prefaced turns were scrutinized using multimodal conversation analysis, focusing on language, gaze, and material resources. The findings suggest that by producing “and”‐prefaced turns, students orient to task progression. These turns have two functions: task managerial and contribution to the emerging task answer. By using task‐managerial “and”‐prefaced turns, the current speaker invites another student to participate, while in “and”‐prefaced contributions to the task answer, a participant adds to, generalizes, or modifies the previous task answer. The analysis shows that students mobilized their L2 interactional competence in producing “and”‐prefaced turns in close coordination with embodied resources and with respect to the spatio‐material surroundings and the nature of the task. These findings contribute to the multimodal reconceptualization of the grammar–body interface and research on turn‐initial particles within L2 interactional competence.

AbstractBackgroundAnxiety is a prevalent mental disorder among the elderly, leading to discomfort, disability, increased expenses, reduced quality of life, and dysfunction. Consequently, this study was conducted to determine the prevalence of COVID‐19 anxiety and geriatric anxiety, along with the factors influencing anxiety, in the elderly population served by urban healthcare centres in Quchan.MethodsThis cross‐sectional study involved 650 elderly individuals aged 60–95 years. The participants were selected using a two‐stage cluster sampling method. Data were collected through three questionnaires: the Geriatric Anxiety Inventory (GAI), the Corona Disease Anxiety Scale (CDAS), and a questionnaire on factors contributing to anxiety. Data analysis was performed using simple and multiple regression with IBM SPSS 24.ResultsThe prevalence of geriatric anxiety among the elderly was 40.3%, while the prevalence of COVID‐19 anxiety (moderate and severe) was 22.8%. Significant relationships were observed between geriatric anxiety and substance abuse, stressful life events, comorbidities, COVID‐19 anxiety, financial support, loneliness, walking habits, and sleep patterns (P < 0.05).ConclusionCOVID‐19 anxiety and geriatric anxiety are prevalent concerns among the elderly. Factors like substance abuse, stressful life events, COVID‐19‐related anxiety, comorbidity, living alone, lack of financial support, and poor walking and sleeping habits, which affect anxiety in the elderly, it is essential to address these factors in life planning and provide services through relevant organisations, healthcare teams, and initiatives by the elderly themselves.
The Calkin algebra, Kazhdan's property (T), and strongly self‐absorbing C∗$\mathrm{C}^*$‐algebras
Authors: Farah Ilijas 
Published: November 2023

AbstractIt is well known that the relative commutant of every separable nuclear ‐subalgebra of the Calkin algebra has a unital copy of Cuntz algebra . We prove that the Calkin algebra has a separable ‐subalgebra whose relative commutant has no simple, unital, and noncommutative ‐subalgebra. On the other hand, the corona of every stable, separable ‐algebra that tensorially absorbs the Jiang–Su algebra has the property that the relative commutant of every separable ‐subalgebra contains a unital copy of . Analogous result holds for other strongly self‐absorbing ‐algebras. As an application, the Calkin algebra is not isomorphic to the corona of the stabilization of the Cuntz algebra , any other Kirchberg algebra, or even the corona of the stabilization of any unital, ‐stable ‐algebra.

AbstractRecent applications of machine-learned normalizing flows to sampling in lattice field theory suggest that such methods may be able to mitigate critical slowing down and topological freezing. However, these demonstrations have been at the scale of toy models, and it remains to be determined whether they can be applied to state-of-the-art lattice quantum chromodynamics calculations. Assessing the viability of sampling algorithms for lattice field theory at scale has traditionally been accomplished using simple cost scaling laws, but as we discuss in this work, their utility is limited for flow-based approaches. We conclude that flow-based approaches to sampling are better thought of as a broad family of algorithms with different scaling properties, and that scalability must be assessed experimentally.

Furthermore, several physical properties of compact stellar structures are examined in order to achieve the physical validity and stability for considered models. The graphical analysis including energy density, pressure components, equation of state parameters, and energy conditions are examined. Moreover, the equilibrium conditions through Tolman–Oppenheimer–Volkoff equation and stability criteria through adiabatic index for the charged stellar structure study are investigated.

Probabilistic models for understanding inland amphipods water population abundances in Andean stream (Caspana, 23°S, Antofagasta region, Chile)
Authors: De los Ríos-Escalante Patricio , Wilson Rodolfo , Esse Carlos 
Published: November 2023

Abstract
The Andes mountains in northern Chile have numerous small permanent and intermittent streams that are poorly studied; among the most reported species are amphipods of the genus Hyalella, specifically H. fossamanchini and H. kochi. The aim of the present study was to do a first characterization of populations of both amphipod species in a small stream (Caspana, 23°S; 3200 m a.s.l.), that was visited in September 2022. The first results using a Kruskall-Wallis nonparametric test revealed that the abundances of both species and unidentified juveniles were not significantly different in a comparison of two sites, whereas a Mann-Wittney nonparametric U test gave similar results when each species and juveniles were compared between sites. The results of variance/mean ratio revealed the existence of an aggregated pattern, and a negative binomial distribution for all samples. The occurrence of an aggregated pattern and the consequent negative binomial distribution is a very frequent pattern for inland water invertebrates in Chilean rivers.
“Beating the Drums in God’s Wrestling Arena”: Spirituality Translated into Local Metaphor in Wolof Sufi ʿAjamī Poetry
Authors: Ndiaye Gana , Rowley Margaret , Diagne Elhadji Djibril 
Published: November 2023

Abstract
How do ʿAjamī scholars translate Sufi spirituality and esoteric concepts into a language accessible to their audience? The body of Senegalese Wolof ʿAjamī poetry often seeks to translate divine concepts into a language that is local, both in time and place. This translation takes place within the local language in all of its literary dimensions. For the Wolof ʿAjamī poet, proverbs, parables, and metaphors are key literary devices that facilitate understanding among listeners. Studying ʿAjamī poems opens a window into a historic locality, teaching the contemporary reader-listener about both Sufi spirituality and the particular contexts in which the poems were produced. Through these metaphors, the poet ʿAjamizes, conferring sacred meaning onto practices and devices that otherwise might be outside the Sufi realm. In the process, metaphors become vessels of divine meaning. This article treats the metaphor as a key literary device whose understanding is paramount for grasping the meaning of the religious message. Treating the poems as social documents and works of literature also offers scholars new possibilities for understanding the everyday life of ordinary users in Senegambia.
Lives of Patriarchs, Lives of Qadis: Reading the Abbasid Sources of the “History of the Patriarchs” as Islamicate Texts
Authors: Palombo Cecilia 
Published: November 2023

Abstract
This article discusses the literary representation of religious leadership in the Siyar al-bīʿa al-muqaddasa, also known as “History of the Patriarchs of Alexandria”. It suggests reading accounts on early Muslim rule within the frameworks of Islamicate literature from the Abbasid and the Fatimid periods, when the collection was created, also considering successive layers of redaction. This approach contrasts with a more conventional way of reading such texts as historical sources on Christian-Muslim relations and as witnesses of the early Islamic period. By comparing stories of patriarchs and rulers with stories about qadis and rulers, the article highlights the importance of framing early Islamicate Christian sources in relation to a broader cultural context and historical developments, without exaggerating their early dating. Finally, it proposes that there is historical meaning to be found in the display of linguistic and narrative anachronisms.
Patriarcat, califat et réseaux : le moment Ḥarrān au cœur de l’Empire (126/744-140/758)
Authors: Pierre Simon 
Published: November 2023

Abstract
This paper offers a cross-analysis of Syriac and Arabic sources related to the Jazīra, the northern province of the caliphate, during the second/eighth century. Specifically, it delves into what the author refers to as the “Ḥarrān moment”. It pertains to the period when this regional town was turned to the last capital of the Umayyads, and immediately to the centre of the provincial government of the future caliph al-Manṣūr, prior to his ascent to power in 754-755 CE. The study views the Abbasid revolution as part of a single decade of civil war (fitna) (744-755) and emphasises the continuity between two dynasties, challenging the traditional historiographical divide of the “Abbasid revolution.” The “Ḥarrān moment” marked a significant shift in central political (and ecclesiastical) power from Umayyad Damascus to Abbasid Baghdad. Syriac sources underscore the centrality of the Jazīra and its capital, as well as the similarities in the political and military history before and after 132/750. Moreover, local ecclesiastical chronicles highlight how Ḥarrān became the centre of the Church at that time, partly by chance and partly due to geopolitical and geo-ecclesiological co-construction. It is argued that this results from a period when prelates and patriarchs became more courtiers, and both Marwān II and al-Manṣūr initiated a policy of affiliation of the Syrian Orthodox Church to the Caliphate, particularly through the issuance of diplomas (sigillions). This article demonstrates that the physical encounter of these two central powers, civil and ecclesiastical, in this strategic location during this critical time of interconnected political-military and ecclesiological turmoil and changes of the 740s-750s, is the key to understanding this process. The study specifically examines the similarities between monastic and tribal provincial and infra-provincial networks, which arise from the same political constraints, to explore the formation and crystallisation of parallel regional ecclesiastical and political blocks during the mid-eighth century CE.

Objective: Public health agencies have a critical role in providing effective messaging about mitigation strategies during a public health emergency. The objectives of this study were (1) to understand perceptions of COVID-19 vaccines, including concerns about side effects, safety, and effectiveness and how these perceptions influence vaccine decision-making among US adults and (2) to learn what messages might motivate vaccine uptake. Methods: In April and May 2021, we conducted 14 online focus groups with non-Hispanic English-speaking and English- and Spanish-speaking Hispanic adults (N = 99) not vaccinated against COVID-19. We oversampled adults aged 18-39 years and rural residents and systematically assessed 10 test messages. Researchers used a standardized guide and an a priori codebook for focus group discussions, coding transcripts, and thematic analysis. Results: Vaccine hesitancy factors included fear of the unknown; long-term side effects, including infertility; and beliefs that the vaccines were developed too quickly and were not sufficiently effective. Motivating factors for receiving vaccination included the ability to safely socialize and travel. Health care providers were considered important trusted messengers. Participants were critical of most messages tested. Messages that came across as “honest” about what is not yet known about COVID-19 vaccines were perceived more positively than other messages tested. Messages were seen as ineffective if perceived as vague or lacking in data and specificity. Conclusions: Messages that were simple and transparent about what is unknown about vaccines relative to emerging science were viewed most favorably. Health care providers, friends, and family were considered influential in vaccination decision-making. Findings underscore the benefits of research-informed strategies for developing and disseminating effective messages addressing critical issues in a public health emergency.
Developing Attributes of the Leader: From Military Service to the Civilian Workforce
Authors: Henderson Latosha R. 
Published: November 2023

The ProblemOrganizations struggle to find effective ways to identify needs and consequently develop the leadership skills of leaders. At the same time, veterans are entering the civilian workforce with significant, valuable non-technical leadership skills that are rarely studied as leadership attributes. As a result, there is scant research on the contribution of leadership attributes from military leadership.The SolutionThis article will introduce the Be-Know-Do framework used in the U.S. Army’s leadership development program. The premise of the model is that when the attributes and competencies of the leader are developed, organizational results will be produced through the people they lead.The StakeholdersHuman resource development (HRD) scholars and practitioners, human resource management (HRM) practitioners, professionals, and trainers

Published: November 2023

Background Endoscopic tattooing of colorectal lesions has been performed employing several markers. The indocyanine green (ICG) that uses near infrared fluorescence technology, has been recently adopted in laparoscopic colorectal cancer surgery. This study aims to systematically review the international literature to validate the ICG in laparoscopic colorectal surgery, in order to include the ICG in the therapeutic protocol. Methods Following AMSTAR 2 criteria, we performed a systematic review to evaluate the use of green indocyanine as a marker for preoperative endoscopic tattooing and for lymph nodes mapping. The study selection was conducted using the PubMed database from January 1989 to July 2022. Results We identified 25 eligible studies. 13 based on fluorescent tumor localization in laparoscopic colorectal surgery using ICG while 12 of them reported the lymphatic road mapping and sentinel node identification by ICG using a near-infrared camera system. One study analyzed both topics. Conclusions In laparoscopic colorectal cancer surgery indocyanine green can be used to localize fluorescent tumors and mapping fluorescence lymph node. The use of ICG appears to be a valid and safe technique that helps the surgeon to achieve a better oncological radicality. However, the protocols need to be clarified by further studies.
Curcumin's Dose-Dependent Attenuation of Gastric Cancer Cell Progression Via the PI3K Pathway Blockade
Authors: Xi Gen , Dong Qingtao , Yang Bo , Jiao Desheng , Khan Shahanavaj 
Published: November 2023

Background: Gastric cancer stands as a primary cause of cancer-related deaths worldwide, making the discovery of new therapeutic agents essential for enhancing treatment outcomes. Curcumin, a polyphenolic compound found in turmeric ( Curcuma longa), has demonstrated potential in multiple cancer types due to its anti-cancer characteristics. This research aimed to examine the impact of curcumin on gastric cancer cell growth, migration, and invasion, as well as its influence on the phosphoinositide 3-kinase (PI3K) signaling cascade. Methods: Gastric cancer cell lines were exposed to varying curcumin concentrations, followed by assessments of cell viability, migration, and invasion. Furthermore, gene and protein expression levels associated with the PI3K signaling cascade were evaluated using reverse transcription-polymerase chain reaction (RT-PCR) and Western blot analysis. Results: The findings revealed a dose-dependent decrease in cell viability, migration, and invasion in gastric cancer cells treated with curcumin. Additionally, curcumin administration led to the downregulation of key genes and proteins within the PI3K signaling process, such as PI3K, Akt, and mTOR. Conclusion: These findings propose that curcumin may exercise its anti-cancer effects on gastric cancer cells, partly by suppressing the PI3K signaling pathway. This study's outcomes support curcumin's potential as a therapeutic agent for gastric cancer and encourage further exploration of its underlying molecular mechanisms and in vivo effectiveness.

Abstract
Background
This research evaluated the anti-Candida albicans effect of Mexican propolis from Chihuahua.
Chemical composition of the ethanolic extract of propolis was determined by GC-MS, HPLC-DAD, and HPLC-MS. The presence of anthraquinone, aromatic acid, fatty acids, flavonoids, and carbohydrates was revealed.

Results
The anti-Candida activity of propolis was determined. The inhibitions halos were between 10.0 to 11.8 mm; 25% minimum inhibitory concentration (0.5 mg/ml) was fungistatic, and 50% minimum inhibitory concentration (1.0 mg/ml) was fungicidal.
The effect of propolis on the capability of C. albicans to change its morphology was evaluated. 25% minimum inhibitory concentration inhibited to 50% of germ tube formation.
Staining with calcofluor-white and propidium iodide was performed, showing that the propolis affected the integrity of the cell membrane.
INT1 gene expression was evaluated by qRT-PCR. Propolis significantly inhibited the expression of the INT1 gene encodes an adhesin (Int1p).
Chihuahua propolis extract inhibited the proliferation of Candida albicans, the development of the germ tube, and the synthesis of adhesin INT1.

Conclusions
Given the properties demonstrated for Chihuahua propolis, we propose that it is a candidate to be considered as an ideal antifungal agent to help treat this infection since it would not have the toxic effects of conventional antifungals.

AbstractBackgroundOne of the most common complications in patients with febrile neutropenia, lymphoma, leukemia, and multiple myeloma is a bloodstream infection (BSI).ObjectiveThis study aimed to evaluate the antibiotic resistance patterns, virulence factors, biofilm-forming strength, and genetic linkage ofEscherichia colistrains isolated from bloodstream infections (BSIs) of leukemia patients.MethodsThe study conducted in Iran from June 2021 to December 2022, isolated 67E. colistrains from leukemia patients’ bloodstream infections in hospitals in two different areas. Several techniques including disk diffusion and broth microdilution were used to identify patterns of antibiotic resistance, microtiter plate assay to measure biofilm formation, and PCR to evaluate the prevalence of different genes such as virulence factors, toxin-antitoxin systems, resistance to β-lactams and fluoroquinolone antibiotics ofE. colistrains. Additionally, the genetic linkage of the isolates was analyzed using the Enterobacterial Repeat Intergenic Consensus Polymerase Chain Reaction (ERIC-PCR) method.ResultsThe results showed that higher frequency of BSI caused byE. coliin man than female patients, and patients with acute leukemia had a higher frequency of BSI. Ampicillin and Amoxicillin-clavulanic acid showed the highest resistance, while Imipenem was identified as a suitable antibiotic for treating BSIs byE. coli. Multidrug-resistant (MDR) phenotypes were present in 22% of the isolates, while 53% of the isolates were ESBL-producing with theblaCTX-M gene as the most frequent β-lactamase gene. The fluoroquinolone resistance genesqnrB andqnrS were present in 50% and 28% of the isolates, respectively. More than 80% of the isolates showed the ability to form biofilms. ThetraT gene was more frequent than other virulence genes. The toxin-antitoxin system genes (mazF,ccdAB, andrelB) showed a comparable frequency. The genetic diversity was detected inE. coliisolates.ConclusionOur results demonstrate that highly diverse, resistant and pathogenicE. coliclones are circulating among leukemia patients in Iranian hospitals. More attention should be paid to the treatment and management ofE. colibloodstream infections in patients with leukemia.
