Life-threatening Lymphatic Malformation With Somatic Activating NRAS Mutation Successfully Treated With Trametinib: A Case Study
Authors: Zumwalt Lindsay , Schluterman Haley , Ray Anish , Heym Kenneth
Published: January 2025

Kaposiform lymphangiomatosis (KLA) is a rare and aggressive subtype of complex lymphatic anomalies (CLA), characterized by abnormal lymphatic proliferation leading to distinct clinical manifestations. Despite the complexity of this condition, there is no established standard therapy, and treatment options such as sclerotherapy, laser therapy, and surgery remain variably effective and are limited to symptom management rather than curative. Sirolimus, an mTOR pathway inhibitor, has shown promise as a primary therapy, particularly in patients without a driver mutation. However, in some instances, the genetic landscape of KLA has revealed somatic mutations in the RAS-MAPK pathway, most notably the NRAS variant (c.182A>G, p.Q61R), representing a potential therapeutic target. We present a case of a 4-year-old male who presented with pericardial and pleural effusions without notable coagulopathy found to harbor an NRAS p.Gln61Arg gene mutation, diagnosed through next-generation sequencing (NGS) analysis. Initial therapy with sirolimus failed to provide optimal benefit with persistent pleural effusion. Subsequent treatment with the MEK inhibitor trametinib led to significant clinical improvement, evidenced by the resolution of effusions and removal of the chest tube. In the short term, no significant adverse effect was reported. Our findings underscore the value of genomic profiling in guiding personalized treatment strategies for rare and complex diseases presenting like KLA. This case highlights the potential of targeted therapies, such as trametinib, in improving clinical outcomes for patients with disease with activating NRAS variants, emphasizing the importance of ongoing research to validate and expand these therapeutic approaches in the management of vascular anomalies.
Psychogenetic Features of Heredity and Pathology
Authors: Spytska Liana
Published: January 2025

The purpose of this study is to provide an in-depth examination of the complex aspects of hereditary and pathological conditions arising based on psychogenetic factors, in particular, the disclosure of elements that determine the causes of their appearance. The following methods were used in the study: analytical, typological approaches, and generalization. It was found that genetic inheritance plays a significant role in the occurrence of autism spectrum disorders, bipolar disorder, schizophrenia, and other pathologies. The study revealed that the presence of a hereditary predisposition significantly increases the risk of developing these disorders in offspring. Genetic variations can affect various aspects of mental functioning and the molecular processes underlying these disorders. However, the important role of environmental factors in interaction with genetics has also been revealed. As part of this study, a plan was developed for a psychotherapist to work with parents raising a child with a mental disorder.

Authors: Naamala Allen M. , Kabir Zarina N. , Orem Jackson , Nalwadda Gorrette K. , Muwanguzi Patience A. , Wettergren Lena
Published: January 2025

Background:

The experiences of adult cancer patients in low-income countries regarding health care and infrastructure are largely undocumented. This study aimed to describe the experiences of adult men and women receiving treatment at a specialized cancer facility in Uganda.

Method:

Thirty-two adult patients with cancer (≥18 years) with varying cancer diagnoses participated in 5 focus group discussions and a key informant interview at Uganda's specialized oncology facility. The interactions were audio-recorded, transcribed verbatim, and analyzed using thematic analysis.

Results:

The participants had both advanced and early stage cancers of varying ages (19–79 years). Four themes emerged: the Organization of care, Personal challenges, Mental suffering, and Satisfaction with care. The Organization of Care theme included categories describing rough sleep, poor food supply, inadequate facilities, and drug shortages. Personal challenges include high treatment costs and delays in accessing care. Mental suffering comprises of 4 categories: stigma, isolation, abandonment, and emotional distress. Satisfaction with care included improve health outcomes and professionalism.

Conclusion:

Participants predominantly reported negative experiences, whereas those with early stage disease primarily emphasized positive experiences. It is imperative for nurses to heighten their awareness of cancer and its treatment, cultivate empathy, and engage positively with both patients and their families. Further research on healthcare professionals' experiences regarding cancer care is needed to gain a comprehensive understanding of cancer care in Uganda.

Authors: Gresits Orsolya Zsuzsanna , Vezér Mátyás , Engh Marie Anne , Szabó László , Molnár Zsolt , Hegyi Péter , Terebessy Tamás
Published: January 2025

Objectives

This systematic review and meta-analysis of randomized controlled trials aimed to summarize the reported functional effects of upper limb botulinum toxin treatment in children with spastic cerebral palsy.

Design

Six databases were searched in October 2022. Two independent authors screened and extracted data on upper limb function, body function, life quality, muscle tone, spasticity, goals, pain, adverse events, and client satisfaction. A random effect model meta-analysis was performed, and RoB 2 and GRADE pro tools were used.

Results

A total of 4862 publications were screened, 14 trials (621 patients) included. Pooled analyses confirm a decrease in muscle tone: mean difference Ashworth scale wrist −0.85 (95% confidence interval = −1.42 to −0.27). No significant functional gain was established: Melbourne Assessment mean difference 3.13 (95% confidence interval = −3.13 to 9.3), and Assisting Hand Assessment mean difference 3.84 (95% confidence interval = −1.86 to 9.54). Botulinum toxin groups had better goal achievement: Goal Attainment Scaling T scores mean difference 9.55 (95% confidence interval = 6.05 to 13.04) and better client satisfaction: improvement had an odds ratio of 8.44 (95% confidence interval = 1.34 to 53.08).

Conclusions

Results suggest that upper limb botulinum toxin treatment is effective to decrease muscle tone, but functional benefits are not clearly established. The discrepancy between subjective and objective results requires further investigation.

Authors: Santry Laura A. , Giordano Kathryn , Mower Andrew , Hubbard Jennifer , Thomas James , Scott Rodney C. , Chara Karina , Zent James , Zomorrodi Arezoo
Published: January 2025

Introduction:

Pediatric seizures account for approximately 1% of emergency department (ED) presentations. Laboratory evaluation and emergent electroencephalogram (EEG) are not indicated in patients with a new-onset, unprovoked, afebrile seizure with a normal physical examination. This study aimed to reduce unnecessary ED resource utilization.

Methods:

Through plan-do-study-act cycles from March 2021 to July 2023, a multidisciplinary team implemented change concepts, including creating a clinical pathway and supporting order sets, scheduling outpatient EEGs from the ED, and automating messages to the neurology team to ensure patient follow-up. The primary outcome measure was the percentage of qualified patients who received an EEG in the ED. Secondary outcome measures were the percentage of patients who had ED complete blood counts or neurology consults, the room-to-discharge time in minutes, and healthcare cost per patient. The balancing measure was the 30-day ED bounce-back rate.

Results:

Thirty-four and 99 patients met the inclusion criteria for the baseline and implementation phases, respectively. ED EEGs decreased from 59% to 1%. Complete blood counts and neurology consults decreased from 50% to 16% and 90% to 31%, respectively. Room-to-disposition time decreased from 308 to 203.5 minutes. Preliminary healthcare cost per patient decreased by $630. The 30-day bounce-back rate increased from 0% to 8%.

Conclusions:

Implementing a new-onset seizure pathway decreased ED resource utilization, shortened room-to-discharge time, and lowered healthcare costs.
Comparison of Accuracy in Mandible-First and Maxilla-First Approaches in Bimaxillary Orthognathic Surgery: A Meta-Analysis
Authors: Zhao Chenjie , Gu Tianyi , Bai Xueshan , Lu Jianjian , Teng Li , Yang Liya
Published: January 2025

This meta-analysis compares the accuracy of mandible-first and maxilla-first approaches in bimaxillary orthognathic surgery to improve clinical decision-making. A systematic search was performed in PubMed, Web of Science, Embase, and Cochrane databases up to August 2024. The analysis included randomized controlled trials and cohort studies with a minimum of 10 patients. Data extraction followed Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, and pooled effect estimates for continuous outcomes were calculated using weighted mean difference (WMD) with 95% CIs. Heterogeneity was assessed using Cochran I
2 and Q statistics, with a random-effect model applied when I
2 exceeded 50%. Seven studies involving 316 patients were included. The analysis showed no significant differences in vertical (WMD: −0.05, 95% CI: −0.57 to 0.48, P = 0.86), transverse (WMD: −0.17, 95% CI: −0.43 to 0.09, P = 0.21), and sagittal (WMD: −0.41, 95% CI: −0.98 to 0.15, P = 0.15) surgical errors between the two approaches. Rotational surgical errors were also similar, including pitch (WMD: 0.07, 95% CI: −0.11 to 0.25, P = 0.29), roll (WMD: 0.01, 95% CI: −0.18 to 0.25, P = 0.69), and yaw (WMD: 0.12, 95% CI: −0.56 to 0.81, P = 0.72). The findings suggest that there is no significant difference in surgical accuracy between mandible-first and maxilla-first approaches. Therefore, the choice of sequence should be based on patient-specific factors rather than a presumed advantage of one method over the other. Further research, including large-scale randomized controlled trials, is needed to confirm these results and evaluate long-term outcomes.
A Case of Asymmetric Seizure Termination During an Acute Course of Right Unilateral Electroconvulsive Therapy
Authors: Salzman Brandon C. , Heber Mikhail , Ferber Stephen
Published: January 2025

Electroencephalogram (EEG) monitoring during electroconvulsive therapy (ECT) is commonly done using a 2-channel EEG in order to capture activity from both brain hemispheres, though many institutions may instead opt to utilize a 1-channel EEG, often for reasons of convenience. We present a novel case of asymmetric termination of EEG seizure activity during an acute course of right unilateral ECT, prompting a full neurological workup to investigate potential underlying structural or physiological causative factors. This case assists in informing the necessity of bilateral hemispheric EEG monitoring as well as highlights the importance of searching for undiagnosed or latent neurological dysfunction in certain clinical situations arising during ECT.

Published: January 2025

Background
Whole genome sequencing of bacterial isolates is increasingly becoming routine in clinical microbiology; however, subsequent analysis often needs to be started by a bioinformatician even for comprehensive pipelines. To increase the robustness of our workflow and free up bioinformatician work hours for development and advanced analysis, we aimed to produce a robust, customizable bioinformatic pipeline for bacterial genome assembly and routine analysis results that could be initiated by non-bioinformaticians.
Results
We introduce the RSYD-BASIC pipeline for bacterial isolate sequence analysis and provide a demonstration of its functionality with two datasets composed of publicly available sequences,  in which comparable results are obtained in most cases. In some instances, the pipeline provided additional information, corresponding to in vitro results where these could be obtained. In routine use at our department, the pipeline has already yielded clinically relevant results, allowing us to type a variety of bacterial pathogens isolated in our clinical laboratory. We also demonstrate how RSYD-BASIC results aided in disproving a potential outbreak.
Conclusion
With the RSYD-BASIC pipeline, we present a configurable reads-to-results analysis pipeline operated by non-expert users that greatly eases investigation of potential outbreaks by expert end-users. Results obtained with publicly available sequences show comparable performance to the original methods, while underlining the importance of standardized methods.

Introduction. Genes encoding OXA-48-like carbapenem-hydrolyzing enzymes are often located on plasmids and are abundant among carbapenemase-producing Enterobacterales (CPE) worldwide. After a large bla
OXA-48 plasmid-mediated outbreak in 2011, routine screening of patients at risk of CPE carriage on admission and every 7 days during hospitalization was implemented in a large hospital in the Netherlands. The objective of this study was to investigate the dynamics of the hospitals’ 2011 outbreak-associated bla
OXA-48 plasmid among CPE collected from 2011 to 2021.

Methods. A selection of 86 bla
OXA-48-carrying CPE isolates was made from 374 isolates collected over an 11-year study period. Species included Escherichia coli (Eco), Klebsiella pneumoniae (Kpn), Enterobacter cloacae complex (Ecl), Citrobacter freundii (Cfr), Citrobacter koseri (Cko) and Morganella morgani (Mmo). Short-read sequencing was combined with long-read sequencing for all isolates to reconstruct bla
OXA-48-like plasmids and chromosomes of CPE. MASH, MOBsuite, ResFinder, PlasmidFinder and SNP analyses were performed to study diversity. pOXA-48 plasmids were compared to plasmid sequences that were sequenced for the Dutch CPE surveillance in the same time period.

Results. In total for the 86 CPE, 2 failed genomic assemblies and 78 bla
OXA-48-encoding plasmids were reconstructed, and six bla
OXA-48 genes were located chromosomally. The 2011 outbreak-associated bla
OXA-48 plasmid of 63.6 kb with IncL replicon was found in Cfr, Ecl, Eco, Kpn and Mmo and primarily between 2011 and 2014 and indicated as LR025105 as MASH nearest neighbour. From 2014 onwards, 11 other types of bla
OXA-48-carrying plasmids with different antibiotic-resistant genes and replicons were discovered, representing the earlier defined distinct pOXA-48 plasmid groups found in the Netherlands. Furthermore, on a national level, the LR025105 plasmid was found after 2015 in many different bacterial backgrounds, highlighting the promiscuous nature of this pOXA-48 plasmid.

Conclusion. After a large bla
OXA-48 outbreak in a large hospital in the Netherlands, the composition of the bla
OXA-48 plasmid population in this hospital diversified over time and is in line with national surveillance data. Plasmid sequencing provided valuable insight into the transmission dynamics of bla
OXA-48-encoding plasmids and showed no indication of the persistence of the 2011 bla
OXA-48 plasmid in the hospital environment.

Functional magnetic resonance imaging (fMRI) of the spinal cord is relevant for studying sensation, movement, and autonomic function. Preprocessing of spinal cord fMRI data involves segmentation of the spinal cord on gradient-echo echo planar imaging (EPI) images. Current automated segmentation methods do not work well on these data, due to the low spatial resolution, susceptibility artifacts causing distortions and signal drop-out, ghosting, and motion-related artifacts. Consequently, this segmentation task demands a considerable amount of manual effort which takes time and is prone to user bias. In this work, we (i) gathered a multi-center dataset of spinal cord gradient-echo EPI with ground-truth segmentations and shared it on OpenNeurohttps://openneuro.org/datasets/ds005143/versions/1.3.0, and (ii) developed a deep learning-based model, EPISeg, for the automatic segmentation of the spinal cord on gradient-echo EPI data. We observe a significant improvement in terms of segmentation quality compared to other available spinal cord segmentation models. Our model is resilient to different acquisition protocols as well as commonly observed artifacts in fMRI data. The training code is available athttps://github.com/sct-pipeline/fmri-segmentation/, and the model has been integrated into the Spinal Cord Toolbox as a command-line tool.
Development of avian influenza A(H5) virus datasets for Nextclade enables rapid and accurate clade assignment
Authors: Ort Jordan T. , Zolnoski Sonja A. , Lam Tommy T.-Y. , Neher Richard , Moncla Louise H.
Published: January 2025

The ongoing panzootic of highly pathogenic avian influenza (HPAI) A(H5) viruses is the largest in history, with unprecedented transmission to multiple mammalian species. Avian influenza A viruses of the H5 subtype circulate globally among birds and are classified into distinct clades based on their hemagglutinin (HA) genetic sequences. Thus, the ability to accurately and rapidly assign clades to newly sequenced isolates is key to surveillance and outbreak response. Co-circulation of endemic, low pathogenic avian influenza (LPAI) A(H5) lineages in North American and European wild birds necessitates the ability to rapidly and accurately distinguish between infections arising from these lineages and epizootic HPAI A(H5) viruses. However, currently available clade assignment tools are limited and often require command line expertise, hindering their utility for public health surveillance labs. To address this gap, we have developed datasets to enable A(H5) clade assignments with Nextclade, a drag-and-drop tool originally developed for SARS-CoV-2 genetic clade classification. Using annotated reference datasets for all historical A(H5) clades, clade 2.3.2.1 descendants, and clade 2.3.4.4 descendants provided by the Food and Agriculture Organization/World Health Organization/World Organisation for Animal Health (FAO/WHO/WOAH) H5 Working Group, we identified clade-defining mutations for every established clade to enable tree-based clade assignment. We then created three Nextclade datasets which can be used to assign clades to A(H5) HA sequences and call mutations relative to reference strains through a drag-and-drop interface. Nextclade assignments were benchmarked with 19,834 unique sequences not in the reference set using a pre-released version of LABEL, a well-validated and widely used command line software. Prospective assignment of new sequences with Nextclade and LABEL produced very well-matched assignments (match rates of 97.8% and 99.1% for the 2.3.2.1 and 2.3.4.4 datasets, respectively). The all-clades dataset also performed well (94.8% match rate) and correctly distinguished between all HPAI and LPAI strains. This tool additionally allows for the identification of polybasic cleavage site sequences and potential N-linked glycosylation sites. These datasets therefore provide an alternative, rapid method to accurately assign clades to new A(H5) HA sequences, with the benefit of an easy-to-use browser interface.
VineColD: an integrative database for global historical tracing and real-time monitoring of grapevine cold hardiness
Authors: Wang Hongrui , Londo Jason P.
Published: January 2025

Cold hardiness is a crucial physiological parameter that determines the survival of grapevines during the dormant season. Accurate modeling and large-scale prediction of grapevine cold hardiness are essential for assessing the potential geographic distribution of grapevine cultivation, quantifying the impact of climate change on grapevine habitats, and ensuring the sustainability of the grape and wine industries in cool climate regions worldwide. However, until now, no comprehensive database has been available. In this research, we combined advanced automated machine learning techniques with extensive historical and current weather data to create an integrative database for grapevine cold hardiness: VineColD (https://cornell-tree-fruit-physiology.shinyapps.io/VineColD/). We developed the NYUS.2.1 model, an automated machine learning-based system for predicting grapevine cold hardiness and in this study, applied it to global historical weather data from 17,985 curated weather stations spanning 30° to 55° in both hemispheres from 1960 to 2024, resulting in the development of an integrative grapevine cold hardiness database and monitoring system. VineColD integrates both a global historical dataset and a daily updated regional cold hardiness system, offering a comprehensive resource to study grape cold hardiness for 54 grapevine cultivars. The platform provides multiple download options, from single-station data to complete datasets, and the interactive multi-functional R Shiny application facilitates data analysis and visualization. VineColD delivers critical insights into the impact of climate change on grapevine cultivation and supports a range of analytical functions, making it a valuable tool for grape growers and researchers.

Published: January 2025

Temporomandibular Disorders (TMDs) are musculoskeletal dysfunctions affecting the temporomandibular joint and masticatory muscles, causing pain and functional limitations. The etiology of TMDs is multifactorial, including biological factors, parafunctional habits (such as bruxism), and psychological conditions. This study aims to map and synthesize existing evidence on therapeutic exercise for TMDs.

Inclusion criteria

All primary studies,randomized controlled trials (RCTs), prospective and retrospective observational studies, case studies will be considered.

Methods

This scoping review will be performed in accordance with the Joanna Briggs Institute (JBI) methodology. MEDLINE, Cochrane Central, Scopus, CINAHL Complete, Embase, PEDro and will be searched from inception until now. Additional records will be identified through searching in Google Scholar(the first 5 pages were examined) and Open Grey,,clinicaltrials.gov, Trialsearch.who.int and the reference lists of all relevant studies. No study design, publication type, or data restrictions will be applied. Two reviewers will independently screen all abstracts and full-text studies for inclusion. A data collection form will be developed by the research team to extract the characteristics of the studies included. A tabular and accompanying narrative summary of the information will be provided.

Conclusion

This will be the first scoping review to provide a comprehensive overview and the results will add significant information for clinicians in the management of TMDs with therapeutic exercise. In addition, any gaps in knowledge on the topic will be identified.

ρ0p
correlation functions
Authors: Feijoo A. , Korwieser M. , Fabbietti L.
Published: January 2025

The vector meson-baryon interaction in a coupled channel scheme is revisited within the correlation function framework. As illustrative cases to reveal the important role played by the coupled channels, we focus on the ϕp and ρ0p systems given their complex dynamics and the presence of quasibound states or resonances in the vicinity of their thresholds. We show that the ϕp femtoscopic data provide novel information about a N* state present in the experimental region and anticipate the relevance of a future ρ0p correlation function measurement in order to pin down the S=0,Q=+1 vector meson-baryon interaction as well as to disclose the characterizing features of the N*(1700) state.

Published: January 2025

Lattice QCD results for isospin I=12 Dπ scattering are presented. Utilizing a series of Nf=2+1 Wilson-Clover ensembles with pion masses of mπ≈133, 208, 305, and 317 MeV, various two-particle operators are constructed, and the corresponding finite-volume spectra are determined. The S- and P-wave scattering phase shifts are extracted using the Lüscher approach. A clear trend for the motion of the D0*(2300) pole is identified. With the physical pion mass configurations also included, this calculation constitutes the first lattice calculation in which the pion mass dependence of the D0*(2300) pole is investigated and the scattering lengths are extrapolated/interpolated to the physical pion mass in Dπ scattering.

Barbara Czarniawska (1948–2024): reflections in memory of her work and life
Authors: Sabelfeld Lana , Dumay John , Jönsson Sten , Corvellec Hervé , Catasús Bino , Solli Rolf , Eriksson-Zetterquist Ulla , Raviola Elena , Quattrone Paolo , Guthrie James
Published: January 2025

Purpose

This paper presents a reflection in memory and tribute to the work and life of Professor Barbara Czarniawska (1948–2024).

Design/methodology/approach

We invited those colleagues whom we knew to be close to Barbara to submit reflections about her contributions to academia alongside their memories of her as a person. We present these reflections in the order we received them, and they have only been edited for minor grammatical and punctuation issues to preserve the voice of the contributing authors.

Findings

The reflections in this paper represent different translations of Barbara’s academic and theoretical contributions. However, she also contributed to people. While we can count the number of papers, books and book chapters she published, we must also count the number of co-authors, Ph.D. supervisions, visiting professorships and conference plenaries she touched. This (ac)counting tells the story of Barbara reaching out to work and interact with people, especially students and early career researchers. She touched their lives, and the publications are an artefact of a human being, not an academic stuck in an ivory tower.

Originality/value

A paper in Barbara Czarniawska’s honour where some of her closest colleagues can leave translations of her work through a narrative reflection, seems to be a fitting tribute.
Market reaction to dividend announcements during COVID-19 pandemic in ASEAN countries
Authors: Yudaruddin Rizky , Lesmana Dadang
Published: January 2025

Purpose

This study aims to investigate the market reaction to dividend announcements in five ASEAN countries during the COVID-19 pandemic. We focus on sectors that are less vulnerable during the COVID-19 pandemic, such as communication services, consumer staples, healthcare and information technology.

Design/methodology/approach

A sample of 5,648 dividend announcements from listed companies is utilized for this study, employing the event study method. The market reaction is measured using cumulative abnormal return (CAR), and cross-section regression is employed to examine the determinants of market reaction.

Findings

The findings reveal a significant positive reaction in the communication services, consumer staples, healthcare and information technology sectors following the announcement of an increase or decrease in dividends. These results imply that dividend increase announcements serve as a positive signal for investors amidst the COVID-19 pandemic. However, the market does not respond significantly to announcements of decreased and constant dividends during the pandemic as they are perceived as unfavorable signals. This paper also highlights the role of dividends as a communication tool through which companies express optimism in facing the challenges posed by the COVID-19 pandemic to their investors.

Practical implications

This study highlights the role of dividends as a communication tool through which companies express optimism in facing the challenges posed by the COVID-19 pandemic to their investors.

Originality/value

This study offers a novel cross-country analysis of the market reaction to dividend announcements in the ASEAN region, considering both the pandemic and post-pandemic periods and focusing on sectors less impacted by COVID-19. Unlike previous studies that are limited to single-country or sector-specific analyses, our research uniquely addresses the broader ASEAN context and includes insights into the “new normal” period.

Advanced construction site layout planning for prefabricated projects: an application of the new algorithm
Authors: Pham Vu Hong Son , Pham Duy Hieu
Published: January 2025

Purpose

This study aims to optimize the construction site layout planning (CSLP) problem, with a focus on prefabricated projects. It proposes the use of the oMOAHA algorithm, an enhanced version of the multi-objective artificial hummingbird algorithm (MOAHA), to address challenges related to search space exploration and local optimization in CSLP.

Design/methodology/approach

The study integrates three techniques – opposition-based learning (OBL), quasi-opposition and quasi-reflection – into the initialization phase of the MOAHA algorithm, creating the oMOAHA variant. This model is applied to all three types of CSLP problems – pre-determined location, grid system and continuous space – to evaluate its effectiveness. Six objective functions (three related to cost, two to safety and one to tower crane efficiency) and four site-related constraints are considered through three case studies taken from previous research and one real project involving prefabricated steel structures.

Findings

The oMOAHA algorithm demonstrates superior performance compared to previous models, consistently outperforming traditional approaches in CSLP optimization for prefabricated projects. In the real case study, the proposed model exceeded the actual project plan by 28–43%, indicating its potential to significantly improve both solution quality and project outcomes.

Originality/value

This study is the first to apply an optimization model to all three types of CSLP problems – pre-determined location, grid system and continuous space – within a unified framework. The integration of advanced techniques into the MOAHA algorithm and the model’s successful application in a real prefabricated project underscore its high applicability and effectiveness in modern construction management.
Numerical investigation on hydrothermal characteristics of microchannel heat sinks with PCM inserts for effective thermal management applications
Authors: Korasikha Naga Ramesh , T Karthikeya Sharma , G Amba Prasad Rao
Published: January 2025

Purpose

The purpose of the paper is to develop an efficient thermal management system, which effectively dissipate the heat generated from the electronic devices. The present paper focuses at the modeling of microchannel heat sinks (MCHSs) with phase change materials (PCMs) insets to deal with the fluctuating heat generated from the electronic components.

Design/methodology/approach

In this paper, a novel approach is introduced to enhance the thermal performance of MCHSs through the integration of conjugate heat transfer and energy storage. Numerical investigations were conducted on six novel models of PCM-based hybrid MCHSs using ANSYS-FLUENT. The hydrothermal characteristics of six PCM-based hybrid MCHS models were analyzed and compared with an MCHS model without PCM.

Findings

The numerical model used for this study exhibited a good agreement with existing experimental and simulation results documented in the literature. The hybrid MCHS models developed in the present analysis showed superior thermal characteristics compared to MCHS without PCM. About 12% improvement in the thermal performance factor and a 7.3% reduction in thermal resistance were observed in the proposed MCHS models. A negligible influence of the PCM channel shape and aspect ratio (AR) was observed on the MCHS performance.

Research limitations/implications

As the present work is a numerical investigation, the computational time and computational cost requirements are the main implication for the research.

Practical implications

High pumping power requirement and expensive manufacturing methods of the microfluidic devices are the main practical implications. Leakage problem is also a challenge for development of these heat sinks.

Originality/value

The surge in the heat generated by electronic components is a limiting factor for the conventional MCHSs. To accommodate the surge, researchers have explored energy storage methods using PCM-based passive MCHS but these are effective only during the phase change process. To address this limitation, novel PCM-based hybrid MCHSs, which combine convective heat transfer with energy storage capabilities, have been modeled in the present work. There is an ample opportunity for further exploration of hybrid MCHSs with PCM.
Enhancement of thermo-hydraulic transport within a round tube using a twisted-staggered concave/convex dimples tape

Published: January 2025

Purpose

The purpose of this study is to value the thermal and hydraulic transport augmentation of turbulent fluid flow within the round-pipe axis fixed by a twisted-staggered concave/convex dimples tape.

Design/methodology/approach

This study meets the report’s novel design by axis-inserting a twisted plastic tape with staggered concave/convex dimples of varying diameters (4 and 6 mm) and depths (1, 1.4 and 1.8 mm). Introducing a realizable model integrated with an improved wall function and SIMPLE solving procedure evaluates the thermo-hydraulic transport as Reynolds number is feasible as 5,000, 10,000, 15,000 and 20,000. In addition, using the findings from the present experimental work validates the numerical methodology.

Findings

This paper reveals that the staggered concave/convex dimples on the axis-fixed plastic tape can significantly improve thermo-hydraulic transport within this outer-heated tube. Furthermore, the processed dimples can cause flow disturbance, which increases turbulent kinetic energy and accelerates fluid mixing around a twisted plastic tape, resulting in enhanced thermal convection. The six kinds of twisted tapes (C1−C6) result in the thermo-hydraulic performance index (η) of 1.18–1.32 at Re = 5000. Among all the cases, the dimples using 4 mm combined with 6 mm diameter and 1.4 mm height (C4) earn the highest, around 1.40 at Re = 5,000.

Research limitations/implications

The conditions of constant hydraulic-thermal characteristics of working fluid (air), steady Newtonian fluid considered, and the ignored radiative heat transfer and gravity are the research limitations of the numerical simulation.

Practical implications

The given results can benefit from a round tube design of a thermal apparatus axis fixed by a twisted-staggered concave/convex dimples tape to augment the thermo-hydraulic transport.

Originality/value

Staggered concave/convex dimples on the surface of a twisted tape allow for impinging and swirling flow along the tape. These processed dimples can induce flow disturbance, which increases the turbulent kinetic energy and facilitates fluid mixing in a twisted tape. Furthermore, the hybrid-diameter dimples have enough flow channels for fluid separation-reattachment, and the thermo-hydraulic performance index has improved. This paper then presents a helpful passive approach for cooling a thermal device.
How much AI is too much in assisting evaluation? Chinese applicant reactions to conjoint decisions by experts and algorithm
Authors: Pan Shuyi
Published: January 2025

Purpose

As the use of AI techniques becomes more prevalent in evaluation activities, researchers have suggested integrating AI and human evaluators to address potential AI aversions from applicants. This study was conducted in response to this call, utilizing a Chinese sample.

Design/methodology/approach

This study examined applicants’ responses to decisions made by a human–AI hybrid jury with varying levels of AI agency. Using a three (AI agency: low, medium and high) × 2 (outcome favorability: favorable and unfavorable) between-subjects design, we analyzed the moderated mediation relationship between machine heuristics and organizational assessment, with fairness perceptions serving as a mediator and AI agency level and outcome favorability as moderating variables.

Findings

The results revealed that positive machine heuristics enhanced fairness perception only at high AI agency levels, irrespective of outcome favorability. Negative machine heuristics impaired fairness perception at medium or high AI agency levels only in cases where participants failed the test. Machine heuristics did not directly influence participants’ assessment of the organization but could indirectly influence organization assessments through fairness perception, contingent on the composition of AI agency level and outcome favorability.

Originality/value

By having participants go through a real intelligence exam and explore their experiences, this study had theoretical and practical implications for AI evaluation.
How to enhance company engagement in public-private emergency collaborations in the supply of essential goods
Authors: Lüttenberg Markus , Zienau Alexander , Wiens Marcus , Hansen Ole , Diehlmann Florian , Schultmann Frank
Published: January 2025

Purpose

In crises like natural disasters and the COVID-19 pandemic, public actors might have to take over responsibility for the population’s supply when the market fails to meet the demand for essential goods. Companies can be valuable collaboration partners for public actors. However, conditions under which companies are willing and able to support public crisis management need to be better understood. This paper aims to empirically investigate expectations and motivation to better understand the motives leading companies to participate in public–private emergency collaborations. To enable successful collaboration, the paper develops crisis preparedness guidelines for state institutions and companies.

Design/methodology/approach

The authors develop and conduct a survey and statistically analyze the responses of 398 German companies from the food, health-care and logistics sectors.

Findings

Most companies have already engaged in crisis management and are willing to engage collaboratively. While their preferred contribution to collaborative crisis management is providing resources (e.g. goods or equipment) instead of coordination tasks, they also want to ensure that their business processes are sustained. Among the most promising incentives to increase company engagement are monetary compensation for provided resources and an improved communication policy. Logistics companies are motivated more by relaxing regulations, whereas health-care companies prefer reputation measures.

Practical implications

The insights provide the basis for public and private actors to foster public–private collaboration and raises awareness of its potential during crises. Moreover, this study promotes the systematic implementation of public–private emergency collaborations.

Originality/value

To the best of the authors’ knowledge, this study is the first to empirically investigate the perspective of companies operating in the fields of logistics, food and health-care industries toward public–private collaboration in crisis management.
The key to unlocking implicit status: the effects of interpersonal perceptions and leadership emergence on advice-giving network centrality
Authors: Xu Minya , Liu Beini , Ji Xiaode
Published: January 2025

Purpose

Most existing research has focused on the outcomes of advice-giving network centrality for focal employees, neglecting to address what drives employee centrality in advice-giving networks. Our study aims to explore how and when employees attain a central position in an advice-giving network.

Design/methodology/approach

Through a multi-wave, multi-source survey design, we collected data from 148 full-time employees on 34 newly established self-managed teams. We used Mplus 8 for data analysis and hypothesis testing.

Findings

Interpersonal trust and leadership emergence sequentially mediate the relationship between warmth/competence perceptions and advice-giving network centrality. Employee narcissism weakens the positive relationship between leadership emergence and advice-giving network centrality and further weakens the mediation effects.

Originality/value

Drawing on the social capital theory of career success and the approach-inhibition theory of power, we outline the driving mechanism behind and the boundary condition for advice-giving network centrality. Our findings not only uncover effective career development strategies for employees but also offer practical insights for managers to improve team effectiveness.
Boeing: wait, there’s more
Authors: Shea Gregory P. , Allon Gad
Published: January 2025

Purpose

The unfolding story of Boeing enables increased understanding of what transpired, of how what happened. That understanding enables fuller, more nuanced, specific, and useful recommendations for organizational leaders everywhere.

Design/methodology/approach

Compiling key events in Boeing’s migration from symbol of acclaimed quality products to a troubled maker of a repeatedly (and fatally so) flawed product ground interpretation and extraction of lessons for organizational leaders.

Findings

Restoring Boeing’s legacy of trust and industry leadership would demand more than words. It will demand rethinking strategic direction and implementation, such as restructuring its work systems, particularly the decision-making processes, and aligning them with long-term goals of quality, safety, and innovation. Boeing needs a coordinated effort to rebuild its culture, an effort necessarily comparable to the effort it employed to disassemble it.

Practical implications

This paper assists readers in understanding what underlies the Boeing story, indeed the Boeing tragedy. The facts testify to the decay and rot at Boeing. The facts alone, even when combined with first pass “sense making” under headings such as “culture” and “short term focus”, do not adequately explain what produced the facts. This paper attempts to provide that explanation in the service of furthering learning and improving future actions by organizational leaders, especially concerning their development and implementation of strategy.

Social implications

Boeing offers a cautionary tale-fatality, destruction of value, and erosion of employee well-being. Organizing this tale, as the article does, through both application of theory and extraction of lessons, moves the tale beyond frightening to understanding of underlying leadership and of how to avoid replicating Boeing's tragedy.

Originality/value

This paper assists readers in understanding what underlies the Boeing story, indeed the Boeing tragedy. The facts testify to the decay and rot at Boeing. The facts alone, even when combined with first pass “sense making” under headings such as “culture” and “short term focus”, do not sufficiently explain what produced the facts. This paper attempts to provide that explanation in the service of furthering learning and improving future actions by organizational leaders, especially concerning their development and implementation of strategy.
