Occupational Stress, Strain, and Coping among Nursing Personnel: A Hospital-Based Cross-sectional Study
Authors: Kowshik Shamili , HN Dhanpal , Shil Rahul 
Published: June 2024

Abstract
Background Nurses are the backbone of the health care system and the largest health care force in the world. They work in multidisciplinary areas in hospitals, nursing homes, government and private sectors, and research and development, which makes them the most stressful personnel in clinical areas.
Objectives This paper aims to explore occupational stress, strain, and coping among nurses working in a hospital in Bengaluru.
Methodology A nonexperimental hospital-based cross-sectional study was conducted from November 2, 2022, to December 2, 2022, using a purposive sampling technique. A total of 77 nurses from different areas participated in the study. Data were collected by the researcher himself through the revised version of the Occupational Stress Inventory scale. Descriptive statistics were used with the mean, standard deviation, frequency, and percentage. To check the association, chi-square analysis was used.
Results The research shows that the majority of the nurses had maladaptive stress in terms of role insufficiency, role ambiguity, role boundary, and physical environment (PE). It was observed that there was a high level of vocational strain (VS) and interpersonal strain with an average social support system (SS) among nurses. A significant association was found between gender and occupational role questionnaire (ORQ) factors like PE, designation of the nurse and ORQ in the area of responsibility, and PE of the working area. In the personal strain questionnaire factor, VS was significantly associated with gender. Furthermore, a significant association was also found between gender and personal resources questionnaire factors like self-care coping and SS coping skills.
Conclusion Our data suggested a moderate to high level of occupational stress with less SS among nurses. Consequently, it is imperative for health care organizations to acknowledge the existence of occupational stress and collaborate toward devising a resolution, enabling nurses to provide patients with optimal care.

Resumen
Introducción No existe una guía para el abordaje del dedo en gatillo. Este estudio caracteriza las perspectivas de los cirujanos de mano en Colombia frente al abordaje de esta enfermedad, pues se estima que sus preferencias constituyen actualmente un factor determinante en el manejo ofrecido.
Materiales y Métodos Estudio de corte transversal que incluyó el censo de cirujanos de mano agremiados durante el 2021 en Colombia. Se creó una encuesta junto a un grupo focal de cinco cirujanos la cual se distribuyó para su diligenciamiento en REDCap.
Resultados La tasa de respuesta fue de 81%. Múltiples factores clínicos son considerados para el diagnóstico. El manejo inicial predilecto es solamente una infiltración con corticoesteroides, excepto en pacientes diabéticos o con bloqueo del dedo, en quienes se prefiere operar, siendo la liberación abierta la técnica más popular. Se considera remisión de la enfermedad al cumplirse seis meses sin síntomas, siendo la satisfacción del paciente el desenlace más relevante.
Conclusión Las perspectivas de los cirujanos de mano divergen, así como los hallazgos en la literatura. Este estudio evidencia la necesidad de generar consensos frente al abordaje, teniendo en cuenta las características individuales relevantes de los pacientes y la experiencia de los cirujanos.

Published: June 2024

AbstractPseudoaneurysm following mechanical thrombectomy (MT) is a rare but possible complication associated with endovascular procedures. This report presents a case of delayed rupture of a pseudoaneurysm after MT with a stent retriever, which was confirmed by open surgery. During hospitalization, an 85-year-old woman had right hemiplegia and aphasia. Magnetic resonance imaging and angiography revealed acute ischemic changes in the left middle cerebral artery because of M2 segment occlusion. MT was performed to address persistent M2 occlusion. Retrieving from distal vessels with the fully deployed Solitaire 4 × 20 mm stent retriever was considered dangerous, we resheathed the stent, but the microcatheter jumped distally. Angiography through microcatheter revealed contrast leakage into the subarachnoid space. The diagnosis was vessel perforation caused by the microcatheter. The lesion was treated with temporary balloon occlusion for 5 minutes using a balloon-guiding catheter, combined with the reversal of heparin anticoagulation by protamine, and a systolic blood pressure reduction to below 120 mm Hg. Anticoagulation was initiated after confirming that postprocedural subarachnoid hemorrhage (SAH) decreased 1 day after the procedure. Fourteen days after the procedure, computed tomography and angiography revealed a massive hematoma with a newly formed small pseudoaneurysm at the site of vessel rupture. Open surgery was performed to close the small artery rupture using a clip. Delayed rupture of the pseudoaneurysm occurred after MT using a stent retriever. If SAH is observed after MT, performing follow-up computed tomography angiography or magnetic resonance angiography is recommended to consider pseudoaneurysm formation.
The second mover’s market research dilemma
Authors: Christen Markus , Soberman David A. 
Published: June 2024

AbstractSeveral well-established research streams examine how incumbent firm behavior affects the entry decisions of later entrants, e.g., in terms of herding or differentiation. While it makes sense for a new entrant to take into account an incumbent’s behavior to inform its entry decisions, it would be risky to base such a decision solely on that information. In particular, the potential entrant may also want to conduct its own market research. Naturally, the market research should account for incumbent behavior. Yet, little is known about how a second mover decides where it should conduct market research. Is the information gained from observing the incumbent a substitute or a complement to market research? The information a second mover gathers through observation includes the incumbent’s choice of market. Even more important is the signal generated by an incumbent’s decision to exit or stay in a market. This decision signals to a second mover whether a market is viable, at least for one firm. A second mover that considers entry between an existing market (with an operating incumbent) and a new market (that has no incumbents) chooses between different types of uncertainty. Our paper addresses how this uncertainty affects the second mover’s market research decision. Should a second mover do market research in the competitor’s backyard or should it boldly go where no firm has gone before and research a new market? How is this decision affected by factors such as expected demand conditions and competition? Intuition suggests that information about a virgin market is always more valuable because the first mover already provides information about the existing market. Our research shows that this intuition is not always correct. It is correct when market research generates perfect information. However, market research is rarely perfect. When market research provides estimates subject to an error, a second mover may gain by conducting market research in a market with an existing competitor. Here, the complementarity of the competitor’s performance coupled with market research amplifies the value of the research.

Published: June 2024

Context Most aquatic macrophytes are ecozone-endemic species, and approximately two-thirds of them have rare occurrence at global scale. These small-range plants are seriously under-studied at macroecological scale, despite their marked vulnerability to extinction through habitat loss and climate change. Aims To identify global hotspots of endemism and rarity of aquatic macrophytes and examine the factors that resulted in speciation hotspots of macrophytes in some areas of the planet. Methods We analysed a database of 3499 macrophyte species to locate speciation hotspots and assess the biogeographic and environmental drivers that maintain ecozone-endemic, and globally rare species within their current limited global areas of occupancy. Key results Ecozone-endemic and globally rare macrophyte species hotspots across the planet showed similar occurrence patterns and drivers among ecozones. Ecozone environmental conditions, particularly harsh environments, influenced macrophyte phylogenetic diversity and structure. Most macrophyte species diversification is recent (<10 million years ago). A negative association with bird-mediated zoochory was seen for endemicity and rarity hotspots. Conclusions This study identified hotspots of endemicity and rarity, and potential cradle and museum speciation areas. Implications Our findings could inform global action to conserve the macrophyte diversity of wetlands, and other inland aquatic habitats, across the world.
Crip translingualism
Authors: Canagarajah Suresh 
Published: June 2024

Abstract
Forms of
immobility both limit unqualified human agency and enable diverse channels of mobility. In this sense, mobility and immobility
work together. Certain philosophical movements such as Southern theories and disability studies treat constraints, sedentariness,
and boundaries as needing to be respected and accommodated in any inquiry. This article draws from these schools to theorize
disruptions and constraints as resources in the circulation of languages, texts, and meanings. To index this generative role of
constraints in communication, I adopt the term “crip” from theorizations in disability studies. “Crip” invokes the paradoxical
reality that while being crippled poses disruptions in mobility, this rupture also generates new knowledge and possibilities into
the flow of life (McRuer, 2006). This article explains how crip
translingualism would treat ruptures, constraints, and boundaries as resourceful for meaning making. This is a
corrective to certain previous theorizations that have treated translingualism as based on unrestricted flows and fluidities,
influenced by dominant orientations to mobility. I illustrate from a classroom literacy interaction where the ruptures posed by
the heritage languages of multilingual students motivated everyone to adopt creative strategies to expand the meaning of
“meaning,” redefine literacy as negotiated, and develop ethical dispositions to collaborate in communicating across language
boundaries. I argue that the incomprehensions and vulnerabilities created by language diversity actually motivate everyone to
develop strategies to creatively read and write. In this manner, constraints don’t stifle the text or students, but mobilize new
flows of meanings and interactions.
Backchannels in the lab and in the wild
Authors: Nguyen Allison , Guydish Andrew J. , Fox Tree Jean E. 
Published: June 2024

Abstract
Backchannel choices affect conversational development. Some backchannels invite interlocutors to continue to the
next part of what they are saying and others invite them to elaborate on what they have just said. We tested how communicative
modality (audiovisual, audio, text), environmental setting (wholly in-lab, partially in the wild), and conversational goals
(on-task, off-task) influenced backchannel usage by participants. We found that backchannel production depends on modality,
setting, and goals. For example, we found that specific backchannels played a more prominent role in self-motivated dialogue.
Knowledge of how backchannels are used has both theoretical and practical implications.
Aggression and disagreement in public communication
Authors: Lombardi Vallauri Edoardo 
Published: June 2024

Abstract
The persuasive effectiveness of implicit strategies, associated
with reduced epistemic vigilance, may lead to their exploitation in conveying
doubtful information in advertisement and propaganda. In political
communication, presuppositions tend to specialize for the conveyance of
questionable opinions and self-praise, while implicatures reveal a preferential
association with face-threatening contents in general, where implicitness can
allow speakers to count less evidently as offenders, at the same time being able
to convey contents that can discredit the opponent.
In public debates, speakers do not necessarily aim at convincing
the opponent, but at shaping the beliefs of the public at home. In Italian
broadcast political debates, implicatures and presuppositions are used exactly
with this function. Confirming this pattern, participants in public debates
often “intercept” the opponent’s implicatures and make them explicit in order to
reduce the persuasiveness effected by their being implicit. Sometimes this also
offers the opportunity to provide explicitations that are different from the
original implicature, caricaturizing the position of the opponent with a
strawman effect.
The evidential dimension of implicitly conveyed disagreement in
political debates
Authors: Masia Viviana 
Published: June 2024

Abstract
The idea that manipulation relies more heavily on implicit than
on explicit communication has been the plank of several earlier and recent
debates on argumentation and speaker roles in interactions. The present
contribution will inquire into the selective nature of the use
of implicit communication in political discourse; notably, analyzing the
distribution of presuppositions and implicatures in two political debates, it
will be argued that the use of these two implicit communicative devices – and,
particularly, that of presupposition – is likely to correlate
with the expression of disagreement, notably through aggressive and blasting
contents, more often than with other content types. This tendency will be
accounted for by considering the evidential meaning presuppositions and
implicatures add to an utterance, which contributes to modulating both speaker’s
commitment to truth and source identification on the part of the receiver. Data
also show that, when face-threatening contents are exchanged, presuppositions
epitomize by far the most preferred strategy in both debates.

Abstract
The accurate diagnosis of abnormal electron emission state in hollow cathodes is crucial for the stable operation of Hall electric propulsion systems. In this study, a method of reducing the cathode working gas flow rate was used to simulate abnormal working conditions in which the cathode electron emission state (CEES) was deteriorating. By analyzing and comparing the oscillation signals under abnormal and steady-state working conditions, it was found that as the CEES deteriorated, the power content of the breathing oscillation decreased in the 1–40 kHz frequency band, and the main frequency decreased; in contrast, the power content of the transit-time oscillation increased in the 100–500 kHz range, and the main frequency was on the rise. Combined with the current growth rate analysis of breathing and transit-time oscillations, when the cathode gas flow rate decreases, the CEES deteriorates, the coupling voltage drop increases, and the potential drop in the channel decreases. The electron temperature and nonlinear power absorption of the electrons decrease, leading to a decrease in the growth rate of breathing oscillations and the breathing oscillation weakens; however, the time-averaged ion velocity and ion sound velocity in the channel decrease simultaneously, but the ion velocity decreases significantly faster than the ion sound velocity, leading to an increase in the growth rate of the transit-time oscillation, and the transit-time oscillation strengthen. Through comparison of the oscillation signals under different working conditions, such as varied anode flow rate, anode voltage, magnetic induction, it was proven to be a unique feature of CEES deteriorates, and can be used as an indicator of CEES deteriorates during the on-orbit operation of the Hall-effect thrusters.
Influence of duty cycle on the physicochemical characteristics of an AC-driven argon plasma jet and its impact on hydrogen peroxide production and cell viability

Published: June 2024

Abstract
This paper investigates how the duty cycle influences the production of hydrogen peroxide (H2O2) in an alternating current (AC)-driven plasma jet. H2O2 is a major reactive oxygen species produced by plasma jets in medicine and is a biological important molecule because it can intervene in cellular signaling processes important for disease treatment. In this study, duty cycles were varied from 9% to 72%, which correlated with an increase in the plasma’s dissipated power and UV photon energy density, and consequently an increase in the production of high energy plasma components important for producing H2O2 through electron collision and UV photolysis reactions. Cell media treated with the plasma jet at higher duty cycles correlated with a decrease in the viability of HaCaT keratinocyte skin cells. The AC-driven plasma jets were shown to be operated optimally at a biocompatible gas temperature of below 40 °C whilst still maintaining efficiency in H2O2 production. Overall, the data presented in this study might find use for the future of optimization of the electrical properties of AC-driven plasma jets in plasma medicine.
Enhancement of superconductivity in Zr2S2C arising from phonon softening on transition from bulk to monolayer
Authors: Jamwal Prarena , Ahuja Rajeev , Kumar Rakesh 
Published: June 2024

Abstract
We report a new compound, Zr2S2C, belonging to the transition metal carbo-chalcogenide (TMCC) family. Through first-principles calculations, our analysis of phonon dispersion spectra indicates that the compound is dynamically stable in both bulk and monolayer forms. We systematically investigated the electronic structure, phonon dispersion, and electron–phonon coupling (EPC) driven superconducting properties in bulk and monolayer Zr2S2C. The results demonstrate the metallic character of bulk Zr2S2C, with a weak EPC strength (λ) of 0.41 and superconducting critical temperature (

T

c

) of ∼3 K. The monolayer Zr2S2C has an enhanced λ of 0.62 and

T

c

of ∼6.4 K. The increased λ value in the monolayer results from the softening of the acoustic phonon mode. We found that when biaxial strain is applied, the low energy acoustic phonon mode in monolayer becomes even softer. This softening leads to a transformation of the Zr2S2C monolayer from its initial weak coupling state (λ = 0.62) to a strongly coupled state, resulting in an increased λ value of 1.33. Consequently, the superconducting critical temperature experiences a twofold increase. These findings provide a theoretical framework for further exploration of the layered two-dimensional TMCC family, in addition to offering valuable insights.
Analyses of hydrogen local environments in metals and intermetallic compounds using inelastic neutron scattering calculations based on first-principles hydrogen adiabatic potentials

Published: June 2024

Abstract
This study re-evaluates the theoretical approach to analyzing inelastic neutron spectra of hydrogen-containing metals and intermetallic compounds. Previously, these analyses utilized hydrogen quantum nuclear states, modeled as solutions to the Schrödinger equation. The potential surfaces in these models were approximated from the total energies derived from first-principles electronic structure calculations. The current study improves upon this method by employing more efficient and accurate treatments for sampling the potential surface. It utilizes symmetrically irreducible sampling points arranged on densely populated mesh grids for the first-principles calculations. A comparative analysis of the theoretical predictions with experimental spectra for hydrides of Ti2Sb and Ti3Sb, as well as a LaNi5 hydrogen primary solid solution, demonstrates that this approach is promising for elucidating the unknown local environments of hydrogen atoms in systems where the approximate potential well describes the hydrogen quantum states.

Published: June 2024

Abstract
In this paper,bulk polarization mechanism and radiation simulation of the Al component gradient buffer layer (GBL) and constant buffer layer (CBL) of p-GaN HEMT (p-GaN GBL-HEMT and p-GaN CBL-HEMT) are analyzed and studied. It is found that the p-GaN GBL-HEMT can significantly reduce the buffer leakage current. The linear gradient amplitude (the range of linear gradients of Al components vertically in the buffer) of 20%–25% Al components can significantly increase the breakdown voltage (V
BK) of the device, up to 1312 V. Simultaneously, although the p-GaN GBL-HEMT reduces the 2DEG concentration, the device still has a specific on-resistance (R
ON,sp) and drain saturation current (I
DS,sat) equivalent to the p-GaN CBL-HEMT due to the conductivity modulation effect. Its Baliga figure of merit is up to 2.27 GW cm−2. Finally, through the SEE simulation and the bulk polarization mechanism analysis, it is found that the drain transient current (I
DS,trans) by the identical incident particles in the p-GaN GBL-HEMT is lower than that in the p-GaN CBL-HEMT, and the I
DS,trans decreases with the increase of the Al components gradient amplitude. Therefore, the p-GaN GBL-HEMT provides a new idea for improving the electrical performance and SEE hardening.
