Published: May 2023

Abstract
Introduction  Treatment of Eustachian tube dysfunction has remained an enigma for a long time. Balloon tuboplasty, even though effective, is not considered by many, as it is invasive, expensive, and cumbersome. Hence, we tried to find some simple and inexpensive solution for the same in chronic otitis media. In this background, we evaluated the use of the Eustachian barotubometer to treat obstructive Eustachian tube dysfunction in mucosal chronic otitis media.
Materials and Methods  The pilot study was undertaken in a tertiary referral hospital with 25 cases and 30 controls. Case group patients were administered Eustachian barotubometer therapy along with ciprofloxacin-dexamethasone ear drops and xylometazoline nasal drops until the recovery or up to 10 days. Control group patients received the same ear and nasal drops along with Valsalva maneuver for the same duration.
Results  The recovery of the Eustachian tube was categorized as complete, partial, or nil. It was found that the case group had 60 and 32% complete and partial recovery, respectively, while it was 33.33 and 13.33% in the control group. The recovery was faster with Eustachian barotubometer therapy than with the Valsalva maneuver. No complications were observed with the new procedure.
Conclusion  The Eustachian barotubometer is a simple, inexpensive device that can be used to treat Eustachian tube dysfunction in chronic otitis media. This device is particularly suitable for the peripheral health care centers of developing countries.

Abstract
Objective The aim of this study was to determine the prevalence and types of inner ear and/or cochlear nerve anomalies in children who are candidates for cochlear implantation.
Methods This was a descriptive cross-sectional study with a retrospective review of medical and imaging records performed in a tertiary care children's hospital. All cochlear implants candidates under 15 years old with imaging assessment between January 2019 and December 2021 were concerned. The studied parameters were reason for consultation, risks factors, inner ear malformations (IEMs) classified and stratified by sensorineural hearing loss (SNHL) degree, gender, and age at diagnosis.
Results In total, 81 children (162 ears) were included in the study. Abnormalities of the inner ear were found in nine children representing a prevalence of 11.1%. These children were aged between 2 and 14 years. The average age at diagnosis of SNHL was 3.5 years. Seven children had bilateral anomalies and two unilateral anomalies, that is, 16 ears presenting 40 malformations. These included 1 complete labyrinthine aplasia (2.5%), 12 cochlear malformations (30%), 1 common cavity (2.5%), 17 vestibular/squamous cell carcinoma (SCC) malformations (42.5%), and 5 internal auditory canal malformations (12.5%). Three ear out of 16 with abnormalities demonstrated a deficient cochlear nerve. There was an association between IEMs and profound deafness, and age at diagnosis of SNHL less than 2 years.
Conclusion This study shows that 11.1% of children with profound deafness have IEMs. SCC malformations and cochlear hypoplasia were the most common. A precise description of these malformations during the imaging assessment is particularly useful for cochlear implantation to better plan this surgery.

Published: May 2023

AbstractHealth care throughput is the progression of patients from admission to discharge, limited by bed occupancy and hospital capacity. This study examines heart center throughput, cascading effects of limited beds, transfer delays, and nursing staffing on outcomes utilizing elective surgery cancellation during the initial severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic wave. This study was a retrospective single-center study of staffing, adverse events, and transfers. The study period was January 1, 2018 to December 31, 2020 with the SARS-CoV-2 period March to May 2020. There were 2,589 patients, median age 5 months (6 days–4 years), 1,543 (60%) surgical and 1,046 (40%) medical. Mortality was 3.9% (n = 101), median stay 5 days (3–11 days), median 1:1 nurse staffing 40% (33–48%), median occupancy 54% (43–65%) for step-down unit, and 81% (74–85%) for cardiac intensive care unit. Every 10% increase in step-down unit occupancy had a 0.5-day increase in cardiac intensive care unit stay (p = 0.044), 2.1% increase in 2-day readmission (p = 0.023), and 2.6% mortality increase (p < 0.001). Every 10% increase in cardiac intensive care unit occupancy had 3.4% increase in surgical delay (p = 0.016), 6.5% increase in transfer delay (p = 0.020), and a 15% increase in total reported adverse events (p < 0.01). Elective surgery cancellation is associated with reduced high occupancy days (23–10%, p < 0.001), increased 1:1 nursing (34–55%, p < 0.001), decreased transfer delays (19–4%, p = 0.008), and decreased mortality (3.7–1.5%, p = 0.044). In conclusion, Elective surgery cancellation was associated with increased 1:1 nursing and decreased mortality. Increased cardiac step-down unit occupancy was associated with longer cardiac intensive care unit stay, increased transfer, and surgical delays.
What happens when a country bleeds soft power? Conceptualising ‘Negative Watch’: towards an epistemology for negative and adversarial place branding
Authors: Durrani Sameera 
Published: May 2023

AbstractThis article contends that the classic public diplomacy model prioritising scholarly research on maximising soft power in the eyes of foreign publics needs to be extended. It proposes a new concept, Negative Watch, which dyadically complements Nye’s in (Ann Am Acad Polit Soc Sci 616: 94–109, 2008) idea of soft power. By extending the epistemology surrounding negative place branding, this paper seeks to expand the debates around it. Where soft power is about accruing power via credibility, Negative Watch maps its loss, approaching it from a communicative dimension. Using a case study approach, the article presents the concept as a model with two key components (1) An index comprising a typology of unfavourable narratives connoting negative affect towards nation brands; (2) a heuristic model outlining a spectrum of outcomes precipitated by reputational decline. The index can be used as a self-assessment tool by a nation to track its reputational erosion, so that it may take measures before it progresses too far down the spectrum of consequences. It can also facilitate systemic assessment of external actors, including allies as well as adversaries, to facilitate strategic decision making within the realm of international relations and public diplomacy.
Designing composition ratio of magnetic alloy multilayer for transverse thermoelectric conversion by Bayesian optimization
Authors: Chiba Naoki , Masuda Keisuke , Uchida Ken-ichi , Miura Yoshio 
Published: May 2023

We demonstrated the effectiveness of the machine learning method combined with first-principles calculations for the enhancement of the anomalous Nernst effect (ANE) of multilayers. The composition ratio of CoNi homogeneous alloy superlattices was optimized by Bayesian optimization so as to maximize the transverse thermoelectric conductivity (αxy). The nonintuitive optimal composition with a large αxy of ∼10 A K−1 m−1 was identified through the two-step Bayesian optimization using rough and fine candidate pools. The Berry curvature and band dispersion analyses revealed that αxy is enhanced by the appearance of the flat band near the Fermi level due to the multilayer formation. The magnitude of the energy derivative of the anomalous Hall conductivity increases owing to the large Berry curvature near the flat band along the R-M high symmetry line, which emerges only in the optimized superlattice, leading to the αxy enhancement. The effective method verified here will broaden the choices of ANE materials to more complex systems and, therefore, lead to the development of transverse thermoelectric conversion technologies.
A topic modeling-assisted diachronic study of “One Country, Two Systems” represented in Anglo-American newspapers
Authors: Chen Fu , Wang Guofeng 
Published: May 2023

Abstract
One Country, Two Systems (1C2S) is a framework proposed by China to achieve national unification of territories with different economic and socio-political systems. This study explores the discursive construction of 1C2S in two representative Anglo-American newspapers from January 1984 through March 2020 by taking a topic modeling-assisted critical discourse studies approach. The findings suggest that the foci of coverage change throughout the years, and the reports present an increasingly negative portrayal of 1C2S and growing distrust in its future through the use of a variety of discursive strategies such as predication, intensification, and normalization. In addition to practical concerns of the U.S. and the U.K., these findings are interpreted with regard to the underlying ideological conflicts between socialist China and the two capitalist Western countries. This study also shows the advantage of integrating the topic-modelling approach into discourse studies, especially in terms of diachronic analysis.
The diachronic analysis of resultative constructions
Authors: Yanning Yang 
Published: May 2023

AbstractThis study aims to illustrate a systemic functional framework for analysing the change of constructions which are inherently form-meaning correspondences. The study first discusses the value of systemic functional linguistics (hereafter SFL) to solving the perceived problems arising from the theoretical model of grammaticalisation. The dominance of grammaticalisation theory in historical linguistics has led some to equate grammaticalisation with language change. However, a systematic exploration of the semantic change is frequently lost in the literature on grammaticalisation. SFL, since its beginning in the early 1980s, has become a leading linguistics school in dealing with semantic and lexicogrammatical changes and the mapping between meaning and form. This study proposes a framework in which SFL theories allow us to address the critical issues in construction change, hence providing mechanisms for the diachronic analysis of both semantic and lexicogrammatical changes. On the basis of the framework, this study focuses its analysis on the change of resultative constructions (hereafter RCs) in Old Chinese and Old English. The diachronic analysis shows that new constructions emerge through a cycle of language change in which the interaction of semantics and lexicogrammar plays a central role. In addition, semantic condensing and compacting are critical steps in the creation of new constructions.
Graduating points of view in Spanish written language
Authors: Oteíza Teresa 
Published: May 2023

Abstract
This paper focuses on some language resources for graduating
points of view in written Spanish language in the field of history. The analysis
is framed in systemic functional linguistic theory, a multifunctional theory of
language (Halliday with Matthiessen 2014), and focuses on the appraisal system, which organises
interpersonal meanings at the stratum of discourse semantics in language (Martin and White 2005; Martin 2019; White 2021). In particular, it considers the coupling
and necessary complementarity of graduation and engagement
subsystems, as part of the appraisal system, for building
intersubjectivity in texts. To achieve this purpose, the analysis explores the
role of the Spanish lexicogrammatical system of modality (modalisation
and modulation) in the construction of dialogicity in historical documents.
Our last Luciferian pact?
Authors: Butt David G. 
Published: May 2023

AbstractThe paper argues for a semiotic – in fact, a grammatical – origin to a profound dimension of the human psyche: William James (1890,1920[1892]) observed how there were far reaching effects from what he characterised as the “duplex self”. This ME/I relation requires cohesion, or co-ordination, much as first suggested by Hughlings Jackson and Théodule Ribot in the mid nineteenth century. The analysis of grammatical equations (identifying clauses) by the functional linguist M. A. K. Halliday can be called upon to show how many important relationships are enfolded in the apparently simple syntax of BE, and of some other cognate verbs. Through detailed exemplification, the paper shows how a double narrative of the “self” is an inevitable consequence of the first person taking on different combinations of grammatical address. This semiotic aspect of the psyche is also discussed in relation to bilaterian or “doubles” in a number of human sciences.
A trinocular view of the auxiliary verb will in
COVID-19 briefings from Westminster and Holyrood
Authors: Beauchamp David , Gardner Sheena 
Published: May 2023

Abstract
This corpus assisted investigation of the auxiliary verb
will examines the various modalities and functions realised
in the register of political briefings given by Scottish (Holyrood) and United
Kingdom (Westminster) representatives throughout the first year of the
coronavirus pandemic.
A trinocular approach is taken to consider the lexicogrammatical
environment of will (from around), the discourse semantics of
will (from above) and the relationship between contraction
and meaning (from below).
Our trinocular approach with a focus on will as
a highly frequent item with great meaning potential has enabled us to gain
insights about the nature of how politicians used modality to persuade, organise
and empathise within coronavirus media briefings and thus shape their public
personas as leaders.
Introverts in the Outdoors: Challenging the Extraversion Myth
Authors: Breunig Mary , Dabrowski Hannah 
Published: May 2023

Summary
This case study originated from conversations between a professor and a graduate student/ outdoor experiential practitioner discussing her experiences as a self-identified introvert. In contemplating the topic for the ‘whose bodies belong’, case study special issue, the two of us were drawn to think beyond bodies to psychological attributes and personality traits as well. We believe this to be especially important considering the hegemonic ‘extrovert ideal’, which often prevails in outdoor experiential education, casting introversion as inferior. This case study is both narrative and empirical, conceptually exploring the commonly held assumption that individuals with higher degrees of extroversion are better suited to work in outdoor experiential education settings. Introverted outdoor educators experience an array of unique challenges, including the need to act in ways that are contrary to their quieter tendencies in order to be perceived as effective at their jobs and to express themselves in an assertive and lively manner at job interviews to even be considered for a position. Introverts bring to the workplace and work teams a unique set of skills and talents, including great focus and high levels of productivity. This case will explore the topic of introversion/extroversion through narrative vignettes and evidence-based research, offering recommendations for professional practice.

The Hands as Reflex Republic
Authors: Edwards Terra 
Published: May 2023

AbstractAmong linguists, psychologists, and anthropologists interested in multimodal communication, much attention has been paid to the motor activity of the hands. Psychologists have treated the hands as a window onto the mind and as a facilitator of thought. Linguists have treated the hands as articulators of linguistic signs, and linguistic anthropologists have treated the hands as an integral part of broader, interacting semiotic processes. This essay builds on these approaches by attending to DeafBlind observations about the communicative potential of the hands. Hands are what you touch when you meet someone, and their texture, temperature, and movements remain available to you over the course of an interaction. From the hands' qualities, the rest of the person and their environment can be inferred. From this perspective, the hands appear not only as a window onto the mind, as a facilitator of thought, or as an articulator of signs, but also as a kind of appendage to the self—like cilia, left out in the world to register the dynamics of social life. This suggests new methodological possibilities for analyzing the motoric activity of hands as a sociocultural and biosemiotic problem.
Physical and Kinematical Characteristics of Wolf–Rayet Central Stars and their Host Planetary Nebulae
Authors: Awad Z. , Ali A. 
Published: May 2023

Abstract
We address the physical and kinematical properties of Wolf–Rayet [WR] central stars (CSs) and their host planetary nebulae (PNe). The studied sample comprises all [WR] CSs that are currently known. The analysis is based on recent observations of the parallax, proper motion, and color index of [WR] CSs from the Gaia space mission’s early third release (eDR3) catalog, as well as common nebular characteristics. The results revealed an evolutionary sequence, in terms of decreasing T
eff, from the early hot [WO 1] to the late cold [WC 12] stars. This evolutionary sequence extends beyond [WR] CS temperature and luminosity to additional CS and nebular characteristics. The statistical analysis shows that the mean final stellar mass and evolutionary age of the [WR] CS sample are 0.595 ± 0.13 M
⊙ and 9449 ± 2437 yr, respectively, with a mean nebular dynamical age of 7270 ± 1380 yr. In addition, we recognize that the color of the majority (∼85%) of [WR] CSs tends to be red rather than their genuine blue color. The analysis indicates that two-thirds of the apparent red color of most [WR]s is attributed to the interstellar extinction whereas the other one-third is due to the PN self-extinction effect.

Abstract
Reliable diagnostics that measure the detached state of the ITER divertor plasma will be necessary to control heat flux to the divertor targets during steady state, burning plasma operation. This paper conducts an initial exploration into the feasibility of the divertor shunt diagnostic as a lightweight, robust, and real-time detachment sensor. This diagnostic is a set of shunt lead pairs that measure the voltage drop along the divertor cassette body, from which the plasma scrape-off layer (SOL) current is calculated. Using SOLPS-ITER simulations for control-relevant ITER plasma scenarios, the thermoelectric current magnitude along the SOL is shown to decrease significantly with the onset of partial detachment at the outer divertor target. Electromagnetic modelling of a simplified divertor cassette is used to develop a control-oriented inductance-resistance circuit model, from which SOL currents can be calculated from shunt pair voltage measurements. The sensitivity and frequency-response of the resulting system indicates that the diagnostic will accurately measure SOL thermoelectric currents during ITER operation. These currents will be a good measure of the detached state of the divertor plasma, making the divertor shunt diagnostic a potentially extremely valuable and physically robust sensor for real-time detachment control.
Effects of surface morphology and composition of titanium implants on osteogenesis and inflammatory responses: a review

Published: May 2023

Abstract
Titanium and its alloys have been widely used in bone tissue defect treatment owing to their excellent comprehensive properties. However, because of the biological inertness of the surface, it is difficult to achieve satisfactory osseointegration with the surrounding bone tissue when implanted into the body. Meanwhile, an inflammatory response is inevitable, which leads to implantation failure. Therefore, solving these two problems has become a new research hotspot. In current studies, various surface modification methods were proposed to meet the clinical needs. Yet, these methods have not been classified as a system to guide the follow-up research. These methods are demanded to be summarized, analyzed, and compared. In this manuscript, the effect of physical signal regulation (multi-scale composite structure) and chemical signal regulation (bioactive substance) generated by surface modification in promoting osteogenesis and reducing inflammatory responses was generalized and discussed. Finally, from the perspective of material preparation and biocompatibility experiments, the development trend of surface modification in promoting titanium implant surface osteogenesis and anti-inflammatory research was proposed.

Published: May 2023

Abstract
The development of hydrogel based scaffold with the capability of enhanced antibacterial effects and wound healing is the promising strategy for the treatment of wound tissues with bacterial infection. Herein, we fabricated a hollow channeled hydrogel scaffold based on the mixture of dopamine modified alginate (Alg-DA) and gelatin via co-axial 3D printing for the treatment of bacterial-infected wound. The scaffold was crosslinked by copper/calcium ions, which could enhance the structural stability and mechanical properties. Meanwhile, copper ions crosslinking endowed the scaffold with good photothermal effects. The photothermal effect and copper ions showed excellent antibacterial activity against both Gram-positive (Staphylococcus aureus) and Gram-negative (Escherichia coli) bacteria. Moreover, the hollow channels and the sustained released copper ions could stimulate angiogenesis and accelerate wound healing process. Thus, the prepared hollow channeled hydrogel scaffold might be a potential candidate for promoting wound healing application.
