How higher charmonia shape the puzzling data of the
e+e−→ηJ/ψ
cross section
Authors: Peng Tian-Cai , Bai Zi-Yue , Wang Jun-Zhang , Liu Xiang 
Published: May 2024

Recently, the BESIII collaboration performed a precise measurement of the e+e−→ηJ/ψ cross section. It is puzzling that the resonance parameters of the reported Y(4230) show a substantial divergence from the previously measured results in both the open-charmed and hidden-charmed decay channels, and the line shape asymmetry of the data approaching 4.2 GeV also suggests that it might be difficult to characterize the details of the structure around 4.2 GeV by a single resonance. This has motivated our great curiosity about how the charmonium states are distributed in the measured energy range and how they shape the puzzling data of the e+e−→ηJ/ψ cross section. In this work, we use five theoretically constructed charmonia in the range of 4.0–4.5 GeV, i.e., ψ(4040), ψ(4160), ψ(4220), ψ(4380), and ψ(4415), to apply a combined fit to the data, in which their calculated decay ratios into ηJ/ψ via hadronic loop mechanism are taken as input. The fit results can reproduce the measured cross section data well, especially for the subtle line shape around 4.2 GeV, showing that the structure around 4.2 GeV is possible from the contribution of both ψ(4160) and ψ(4220).

Gravitational waves from domain wall collapses and dark matter in the SM with a complex scalar field
Authors: Pham Hieu The , Senaha Eibun 
Published: May 2024

We study a domain wall induced by spontaneously broken Z2 symmetry and its gravitational wave signature in the standard model with a complex scalar in connection with dark matter physics. In a minimal setup, a linear term of the singlet field is added to the scalar potential as an explicit Z2 breaking term to make the domain wall unstable. We obtain its minimal size from cosmological constraints and show that the parameter space that can be probed by current and future pulsar time array experiments requires the vacuum expectation value of the singlet field to be greater than O(10–100)  TeV, along with a singletlike Higgs mass of O(1–100)  TeV. However, such a region is severely restricted by the dark matter relic density, which places an upper bound on the singlet vacuum expectation value at approximately 200 TeV, and limits the dark matter mass to about half of the singletlike Higgs boson mass.

Authors: Peron Mirco , Saporiti Nicolò , Shoeibi Majid , Holmström Jan , Salmi Mika 
Published: May 2024

PurposeThis works provides a thorough understanding of the challenges and opportunities associated with Additive Manufacturing (AM) adoption in the medical sector. Through this analysis, we aim to better understand when to adopt AM, how to do so, and how such adoption might change in the future.Design/methodology/approachThis research first conducted a systematic literature review (SLR) to identify AM challenges and opportunities in the medical sector, which were then validated through a Delphi study. The 18 Delphi study participants were also asked to suggest countermeasures for the challenges and help identify future AM adoption scenarios. Finally, these findings were analyzed according to the ecosystem pie model to design an ecosystem model for AM in the medical sector.FindingsAmong the 13 challenges and 13 opportunities identified, the lack of a skilled workforce and the responsiveness achievable via AM were by far the most relevant challenge and opportunity. Moreover, the participants identified countermeasures for 10 challenges, as well as three future AM adoption scenarios. Finally, leveraging these findings, an ecosystem model was developed.Originality/valueThis work contributes to the limited understanding of the AM challenges and opportunities in the medical sector. It helps medical practitioners to better understand the challenges and opportunities associated with AM and AM manufacturers to better identify where to focus their R&D efforts and how this would impact future AM adoption levels. Furthermore, this work extends current theory supporting the design of an ecosystem model for AM in the medical sector following the ecosystem pie model.
Theories of digital platforms for supply chain management: a systematic literature review
Authors: Culotta Carina , Blome Constantin , Henke Michael 
Published: May 2024

PurposeDigital platforms transform supply chains. However, no unified theoretical understanding of digital platforms exists. Thus, the underlying research aims at investigating platform theories for supply chain management tasks.Design/methodology/approachThe authors conduct a systematic literature review to identify relevant theories in the context of digital platforms and synthesize the respective findings for supply chain management tasks.FindingsIn total, 43 papers and 41 different relevant theories are identified. The most prominent theories are the resource-based view, transaction cost economics, internalization theory and the dynamic capabilities approach. Digital platforms alter and change the boundary decisions of firms. Therefore, they have various implications for supply chain management tasks such as make-or-buy decisions or the orchestration of resources to sustain a competitive advantage.Practical implicationsThe identified supply chain theories as well as platform theories and their overlap provide a meaningful starting point for discussing and developing new and platform-based supply chain management approaches in the B2B domain.Originality/valueThe conducted systematic literature review provides a first starting point for building a holistic theoretical approach to digital platforms in supply chains. Thus, the paper contributes a missing link for discussing digital platforms and their theoretical foundations for supply chain management tasks.
Drag story hour at public libraries: the reading child and the construction of fear and othering in Swedish cultural policy debate
Authors: Engström Lisa , Carlsson Hanna , Hanell Fredrik 
Published: May 2024

PurposeThe purpose of the paper is to produce new knowledge about the positions that public libraries both take and are given in the conflicts over politics and identity that play out in contemporary cultural and library policy debates. Using conflicts over drag story hour at public libraries as case, the study seeks to contribute to an emerging body of research that delves into the challenges that public libraries as promoters of democracy are confronting in the conflictual political landscape of today.Design/methodology/approachThe paper presents an analysis of debates reported in news articles concerning Drag story hour events held at Swedish public libraries. Utilizing the analytical lenses of discourse theory and plural agonistics, the analysis serves to make visible the lines of conflicts drawn in these debates – particularly focusing on the intersection of different meanings ascribed to the notion of the reading child, and how fear is constructed and used as an othering devise in these conflicts.FindingsDifferent imaginings of the reading child and the construction and imagination of fear and safety shapes the Drag story hour debates. The controversies can be understood as a challenge to the previous hegemony regarding the direction and goals of Swedish cultural and library policy and the pluralistic democratic society these policies are meant to promote.Originality/valueThe paper offers new insights into the consequences of the revival of radical right politics, populism and societal polarization, and the different responses from public libraries.

Published: May 2024

Purpose
This study aims to propose a collaborative knowledge-based ontological research model for designing a collaborative product development process (PDP) while considering different design for X techniques.

Design/methodology/approach
This study follows a thematic literature analysis to identify the key design concepts needed to assess environmental, service, safety, manufacture and assembly, supply chain and quality concerns in developing a collaborative PDP.

Findings
The proposed model provides a guide for methodology, engineering and ontology evaluation metrics (verification, assessment and validation). The findings benefit both practitioners and managers because they address the key knowledge taxonomy needed to assist them in storing information, promoting teamwork and making decisions in a collaborative PDP while incorporating various design for X approaches and product life cycles.

Originality/value
This study introduces a novel knowledge-based collaborative ontological research model, which is specifically designed to tackle the challenges of developing collaborative products in the contemporary landscape. The model presents a significant and valuable contribution to the field by introducing an ontological approach for acquiring, representing and leveraging knowledge in a computer-interpretable format to support the design of collaborative products.

A two-model integrated technology adoption framework for using blockchain in supply chain management: attitude towards blockchain as a mediator
Authors: Jum’a Luay , Mansour Marwan , Zimon Dominik , Madzík Peter 
Published: May 2024

Purpose
This study aims to investigate the intention to use blockchain technology (BT) in the context of supply chain (SC) operations through an integrated technology adoption framework using two well-known models, the unified theory of acceptance and use of technology (UTAUT) and the technology acceptance model (TAM). Moreover, the study looked at the direct effect of TAM and UTAUT elements on attitude toward BT, as well as the role of attitude toward BT as a mediator between TAM and UTAUT elements and intention to use BT.

Design/methodology/approach
The study used a quantitative research method, and a structured questionnaire was used to gather primary data. The final sample, drawn using a convenience sampling that consisted of 273 managers from the Jordanian manufacturing sector. Structural equation modeling statistical method was conducted using the Smart PLS program to test hypotheses in the proposed study framework.

Findings
The study has provided intriguing results. It found that two UTAUT elements, namely performance expectancy and social influence and one TAM element, namely perceived usefulness, have a significant impact on the attitude toward BT. Besides that, the study found that attitude toward BT significantly mediated the relationship between UTAUT-TAM elements and intention to use BT. The findings revealed that three elements namely performance expectancy, social influence and perceived usefulness have statistical significance on intention to use BT through the mediation of attitude. Finally, there is a direct significant positive relationship between the attitude toward BT and intention to use it.

Research limitations/implications
The study helps decision-makers, South Carolina practitioners and academics recognize the fundamental factors that increase manufacturing firms’ intentions to use blockchain in their SCs. This gives decision-makers a better understanding of why users accept or reject BT, as well as how to improve user acceptability through technological design. Future studies should seek for a bigger sample size and use random sampling techniques. Furthermore, the study should be replicated in other industries or developing countries to validate the findings.

Originality/value
There is a scarcity of studies identifying the factors that increase blockchain adoption intention in SCM and developing countries. This study differs in that it examines BT intention to use in the context of SC using an integrated technology adoption framework that uses two well-known models, UTAUT and TAM, whereas other studies typically use only one model/theory. Moreover, given the importance of attitude in behavior, this study also investigated the effect of TAM-UTAUT elements on attitude toward BT, as well as the role of attitude toward BT as a mediator between TAM and UTAUT elements and intention to use BT.
Method as democratizing; through researcher positionality and empirical inclusivity
Authors: Babri Maira 
Published: May 2024

PurposeThe purpose of this paper is to present how my positionality as a researcher aligned with the works of Latour in terms of methodological inspirations and allowed me to develop a critical vantage point and simultaneously adopt a heterogeneously rather than hierarchically informed approach to ordering the world, which I argue serves as a basis for a more inclusive study of management systems.Design/methodology/approachI reflect on my own positionality as a researcher and share how my interpretation of Latour's ontology through some of his ideas and concepts, particularly symmetry, power, translation and agency, allowed me to incorporate and organize heterogeneous actors depicted in different empirical materials into space-time contexts and subsequently theorize organizing and management practices as agential, multiple and becoming.FindingsA base in Latour’s ontology has equipped me with openness towards empirical settings, which I argue retains a democratic approach to theorization, i.e. theorization, which remains mindful of inadvertent assumptions about power, hierarchy or the taken for granted. This approach has also given me a form of personal resilience as a researcher.Originality/valueThe originality of this paper lies in presenting and developing the concept of method as democratizing. I argue that Latour’s approach to the empirical allows for at least two forms of active democratizing, one relating to the researcher as self and the other in how it incorporates the empirical actors into research, making possible the inclusivity of heterogeneity in analyses of organizations and organizing.
Isolating the effect of rater experience as a time‐variant predictor of performance ratings
Authors: Borba Diogo , Spence Jeffrey R. 
Published: May 2024

AbstractA defining but sometimes overlooked characteristic of performance appraisals is that they are cyclical. The cyclical nature of performance appraisals makes it important to consider time‐variant definitions and operationalizations of constructs such as rater experience. In the current study, we work to clarify the association between rater experience and performance ratings by operationalizing rater experience as the number of appraisal cycles raters participated in. We did so while controlling for other similar but distinct operationalizations of experience such as span of control (number of ratees per rater) and familiarity with ratees. Furthermore, we employed a multilevel longitudinal design and analysis that allowed us to model rater experience as a time‐variant predictor of performance ratings and isolate its effects from both between‐rater and organizational context effects. The data were real appraisal data from a large South American company that contained 9233 ratees, across five appraisal cycles from 893 raters in 29 different business units, resulting in 24,608 observations. Our results revealed that rater experience had a small but statistically significant positive association with performance ratings. We also found that familiarity and span of control, were positively and negatively associated with performance ratings, respectively. Implications for practice and research are discussed.
Stonehenge revisited: A geochemical approach to interpreting the geographical source of sarsen stone #58
Authors: Hancock Ronald G. V. , Gorton Michael P. , Mahaney William C. , Aufreiter Suzanne , Michelaki Kostalena 
Published: May 2024

AbstractIt is tempting in material sourcing analyses to treat chemical data primarily as numbers to be sorted, while disregarding their interlinked geochemistries. Consideration of geochemistry, however, often leads to the drawing of more nuanced and reliable conclusions. In this paper we re‐examine data published in 2020, related to the sourcing of stone #58 at Stonehenge, paying attention to geochemistry. We question the potential single‐source interpretation of these data and suggest instead that three to six sources cannot be ruled out.

Published: May 2024

AbstractThis study used a three‐wave longitudinal dataset to: identify adjustment profiles of U.S. Mexican‐origin adolescents based on their physical, academic, and psychosocial health adjustment; track adjustment profile changes throughout adolescence; and examine the associations between cultural stressors, family obligation, and adjustment profile membership over time. Participants were 604 Mexican‐origin adolescents (54% female, Mage = 12.41, SD = 0.97) in Texas (Wave 1: 2012–2015; Wave 2: 2013–2016; Wave 3: 2017–2020). Three concurrent profiles (Well‐adjusted, Moderate, and Poorly‐adjusted) emerged at each wave, whereas three transition profiles (Improved, Stable well‐adjusted, and Overall poorly‐adjusted) were identified across three waves. The results suggest that cultural stressors pose risks for Mexican‐origin adolescents' adjustment, and family obligation values play a protective role in these associations.
The significance of carrying MEFV variants in symptomatic and asymptomatic individuals
Authors: Ben‐Chetrit Eldad , Touitou Isabelle 
Published: May 2024

AbstractFamilial Mediterranean fever (FMF) is an autoinflammatory disease characterized by recurrent attacks of fever, serositis (peritonitis, pleuritis, or synovitis), and erysipelas‐like erythema. Genetic variants in the MEFV gene are associated with this disease. Familial Mediterranean fever is considered an autosomal recessive disease. However, in Middle Eastern countries, a third of the patients expressing FMF manifestations, carry a single mutation only. Moreover, some cases of pure dominant inheritance linked to specific single MEFV variants have also been described. This complex inheritance of MEFV‐associated inflammatory diseases poses a serious challenge when interpreting the results of genetic testing in patients having recurrent fever syndromes. In addition, in certain situations, asymptomatic individuals may be incidentally found to carry MEFV variants. These cases pose the question of their exact diagnosis and whether they should be treated. Previous studies have focused on genetic results interpretations among symptomatic patients. In the current article, we would like to elaborate on the genetic interpretation in cases of symptomatic individuals suspected to have FMF and on asymptomatic individuals carrying MEFV variants. We aim to assist physicians unfamiliar with FMF to cope with genetic results interpretation when facing symptomatic and asymptomatic individuals carrying MEFV variants and suggest a management plan accordingly.

Published: May 2024

AbstractBackgroundThe 2022 mpox outbreak continues, and while progress has been made in prevention strategies and potential treatment options, data on late sequelae following mpox are scarce.ObjectiveThis analysis aimed to assess the incidence of scar formation in individuals affected by the 2022 mpox outbreak.MethodsAll individuals diagnosed with mpox at the Department of Dermatology at the Medical University of Vienna in 2022 were included in this analysis. Follow‐up data were collected throughout November 2023. ‘Scar formation’ was defined as having at least one scar at the former active mpox lesions.ResultsAt our clinic, 28 cases of mpox presented between June 2022 and October 2022 and exclusively occurred in men who have sex with men (100%, 28/28), of whom 46% (13/28) were living with HIV, and 32% (9/28) were using pre‐exposure prophylaxis (PrEP). Secondary bacterial infection of mpox lesions was suspected in six individuals, and all received systemic antibiotics. Overall, 26 were followed up in November 2023 after a median time of 15 months, and scar formations were found in 43% of cases.ConclusionsOur data provide insights into the late yet cumulating disease burden caused by the 2022 mpox outbreak. Highly effective prevention strategies are warranted to overcome the mpox epidemic and its potential late sequelae.

AbstractIntroductionEsophageal safety following radiofrequency (RF) left atrial (LA) linear ablation has not been established. To determine the esophageal safety profile of LA linear RF lesions, we performed systematic esophagogastroduodenoscopy in all patients with intraesophageal temperature rise (ITR) ≥ 38.5°C.Methods and ResultsBetween December 2021 and July 2023, a total of 200 consecutive patients with atrial tachyarrhythmia (ATA) underwent linear ablation with posterior dome (roof or floor) or posterior mitral isthmus line transection. Patients with ITR ≥ 38.5°C were scheduled for esophageal endoscopy ~3 weeks after ablation. Patient and ATA characteristics, procedural parameters, endoscopy findings and ablation lesion data were collected and analyzed.One hundred thirty‐three out of 200 (67%) patients showed ITR ≥ 38.5°C during LA linear ablation. ITR (with maximal temperature of 45.7°C) was more frequently observed during floor line ablation (82% of cases). ITR was less observed during roof line ablation (34%) and posterior mitral isthmus ablation (4%). Endoscopy, performed in 115 patients after 24 ± 10 days, showed esophageal ulceration in four patients (two patients Kansas City classification [KCC] 2a and two patients KCC 2b). No patient showed esophageal perforation or fistula.ConclusionTemperature rise during LA linear ablation is frequent and ulceration risk exists, particularly when floor line is performed. Safety measures are needed to avoid potential severe complications like esophageal perforation and fistula.
A Lagrangian relaxation approach for resource allocation problem with capacity constraints
Authors: Protogyrou Demetra , Hajibabai Leila 
Published: May 2024

AbstractThis study evaluates a capacitated facility location model enhanced with distance constraints for an emergency response problem, ensuring certain neighborhoods remain within an accessible range from facilities following a hurricane. The proposed model takes into account the capacity constraints for drones and vehicles. The model determines optimal locations for facilities and the distribution of supplies across the city. It also specifies which facilities should support the needs of each neighborhood and decides on the appropriate mode of transportation—ground vehicles if possible, or drones if roadways are obstructed. To solve the problem, a Lagrangian relaxation technique is employed, relaxing the constraints related to facility capacity and distance. The numerical results confirm the quality and efficiency of the solutions. The findings indicate that ground transportation is more frequently utilized than drones at each operational facility. A comprehensive set of sensitivity analyses is conducted to examine the impact of various variables and parameters on the solution.
