Authors: Li Xiuwei , Li XingYang , Zhang Guokun , Wang Yu , Liu Qinglei , Li Qiang 
Published: July 2024

Purpose
The purpose of this paper is to investigate the effects of different surface structures, dimensional parameters and cavitation models on the lubrication characteristics of water-lubricated journal bearings.

Design/methodology/approach
In this paper, the coupling iteration method of ANSYS and MATLAB is established to calculate the journal orbits of water-lubricated bearing, and the differences between the journal orbits of the smoothed and the textured water-lubricated bearings are compared and analyzed, and the effects of different bearing materials, L/D ratios and clearance ratios on the lubrication performance of water-lubricated bearings are investigated. The effects of different cavitation models on the static equilibrium position and whirling trajectory of water-lubricated bearings are compared.

Findings
The results show that when the surface texture is distributed in the upper bearing or the bearing elastic modulus decreases, the bearing stability increases. Considering shear cavitation and noncondensing gas, the rotor journal orbits amplitude decreases at high speed with low clearance ratio. A water film test rig for water-lubricated bearings is built to measure the full-circle water film pressure of water-lubricated journal bearings, and the experimental results are compared with the simulation results, which are in good agreement.

Originality/value
The findings provide a theoretical basis for optimizing the structure of water-lubricated bearings.
Exploring authenticity meanings in the global-local continuum: semiotic insights from the Måneskin case
Authors: Corciolani Matteo 
Published: July 2024

PurposeThis article explores brand positioning and authenticity within the global-local continuum, utilizing the evolution of the Italian rock band, Måneskin, as a case study.Design/methodology/approachEmploying Greimas’s (1987) semiotic framework, I analyze social media and media articles on Måneskin’s success, unveiling consumer perceptions of global, local and intermediate brand positionings and related authenticity dimensions. I particularly uncover a narrative centered on “global” versus “local” brand positioning and their counterparts (i.e. “not global” and “not local”), forming a semiotic square.FindingsIn the “global” perception, the band is evaluated in terms of conforming to global standards, while, in the “local” understanding, the emphasis shifts to connections to local roots. In the “glocalization” perspective (global and local), the band’s activities are assessed concerning an integration between global conformity and local connections. The “glalienation” viewpoint (neither global nor local) is related to consistency, in the sense of being unique and avoiding a commitment to either global or local values. The data also highlight issues of inconsistency regarding brand positioning’s contradictions, such as the band’s incoherently merging local and non-local elements.Originality/valueThe proposed structural semiotics approach enriches previous theories by examining authenticity within global-local dynamics, offering insights into various authenticity dimensions and their interplay. It underlines shifts in authenticity perceptions and challenges binary brand positioning, advocating for strategic placement across the global-local continuum. Moreover, it emphasizes leveraging cultural elements and semiotics to effectively communicate authenticity.

Public interactions of auction participants and their impact on online auctions of nonperishable experience goods
Authors: Jaiswal Mayank 
Published: July 2024

PurposeThe Internet has introduced new ways of conducting business. Online auction of nonperishable experience goods (NPEG) items, which are generally rare, expensive and durable and need to be experienced to be valued, is one area that is undergoing significant change. Online auction platforms are encouraging participants to interact publicly in a social media type comment format. This paper investigates how such public interactions impact the auction outcomes of NPEG.Design/methodology/approachAuction records of vintage automobiles sold between 2015 and 2023 on one of the biggest online auction platforms in the USA were collected. The dataset contains multiple variables per record such as winning bid price, number of comments by sellers and browsers and various details of the automobile, for example brand, vintage and mileage. Ordinary least squares was utilized to analyze close to 42,000 records in the dataset.FindingsThe paper found that comments in general are positively correlated with the winning bid; it also found that online buyers value browser comments higher than seller comments. Furthermore, the relationship between vintage and origin country and winning bid is enhanced by browser comments.Originality/valueThis research furthers theory on two fronts. Firstly, we analyze how auction outcomes are impacted when buyers, casual observers and sellers interact with each other publicly when the auction is ongoing. To the best of the author's knowledge, this is one of the first studies that delve into participant interactions in online ongoing auctions. Secondly, we investigate how potential buyers utilize participant interaction information to guide their decisions about the value of NPEG.

Sukuk defaults: on distress resolution in Islamic finance
Authors: Zaheer Sajjad , van Wijnbergen Sweder 
Published: July 2024

Purpose
This study aims to analyze three major defaults on Sukuk since 2007. These case studies make clear that, in most cases, the problems can be traced back to clauses and structures that made the Sukuk more like conventional bonds. The case studies highlighted the importance of the legal institutions of the country where ownership rights are likely to be contested. Strict adherence to Shariah (Islamic Jurisprudence) principles would have considerably simplified restructuring because Shariah compliance implies a clear allocation of property rights: in Sukuk, investors will receive full title to the underlying Sukuk assets in distress situations.

Design/methodology/approach
The study follows a qualitative research method base on detailed case studies of the Sukuk defaults occurred in the aftermath of financial crises 2007. The focus in this paper is on the resolution process following default, not on the reasons why the default was triggered to begin with. The authors analyze the Sukuk defaults from an Islamic finance perspective. Specifically, after providing basic information on each Sukuk (issuer, arranger, SPV, term period, rate of return, etc.), the authors present an exposition of the underlying contracts of each Sukuk, their structure, reasons for defaults and restructuring process thereafter. Finally, the authors provide a discussion on the critical issues related to Sukuk structures, namely, ownership of underlying Sukuk assets, rights of the investors including recourse, if any, to core assets in case of distress, risk factors including legal and Shariah risks regarding Sukuk structures, purchase undertakings and credit enhancements.

Findings
The case studies highlighted the importance of the legal institutions of the country where ownership rights are likely to be contested. Interestingly enough, strict adherence to Shariah (Islamic Jurisprudence) principles would have considerably simplified restructuring because Shariah compliance implies a clear allocation of property rights: in Sukuk, investors will receive full title to the underlying Sukuk assets in distress situations. So, the answer to the question the authors asked, is Islamic Finance failing to deliver on its promises, is a qualified no.

Originality/value
The paper provides in depth analysis of the Sukuk defaults and provide the main reasons for that along with recommendations that compliance to Shariah principles of ownership and risk sharing would reduce incidence of defaults and facilitates restructuring.
Geodesic algorithm: new approach to optimization of temporary fastener arrangement in airframe assembly process
Authors: Lupuleac Sergey , Pogarskaia Tatiana 
Published: July 2024

Purpose
The purpose of the current study is development of effective and fast algorithm for optimization the arrangement of temporary fasteners during aircraft assembly.

Design/methodology/approach
Combinatorial nature, uncertain input data, sensitivity to mechanical properties and geometric tolerances are the specific features of the fastening optimization problem. These characteristics make the problem-solving by standard methods very resource-intensive because the calculation of the objective function requires multiple solution of contact problems. The work provides an extended description of the geodesic algorithm (GA) which is a novel non-iterative optimization approach avoiding multiple objective function calculations.

Findings
The GA makes it possible to optimize the arrangement of temporary fasteners during the different stages of the assembly process. The objective functions for the optimization are number of installed fasteners and quality of contact between joined parts. The mentioned properties of the GA also make it possible to introduce an automatic procedure for optimizing fastener arrangement into everyday practice of aircraft manufacturing.

Practical implications
The algorithm has been applied to optimization of the assembly process in Airbus company.

Originality/value
Performance of the GA is orders of magnitude greater than standard optimization algorithms while maintaining the quality of results. The use of the assembly process specifics is the main limitation of the GA, because it cannot be automatically applied to optimization problems in other areas. High speed of work and quality of the results make it possible to use it for real optimization problems on assembly line in the production of commercial airliners.

AbstractObjectiveDetermine prevalence, risk factors and outcomes of hypertensive disorders in pregnancy (HDP).DesignCross‐sectional analysis of data captured in the Maternal and Perinatal Database for Quality, Equity and Dignity (MPD‐4‐QED) between September 2019 and August 2020.SettingFifty‐four referral level facilities in Nigeria.PopulationWomen whose pregnancy ended (irrespective of the location or duration of pregnancy) or who were admitted within 42 days of delivery.MethodsDescriptive statistics and multilevel mixed‐effects logistic regression models.Main Outcome MeasuresPrevalence of HDP, sociodemographic and clinical factors associated with HDP and perinatal outcomes.ResultsAmong the 71 758 women 6.4% had HDP and gestational hypertension accounted for 49.8%. Preeclampsia and eclampsia were observed in 9.5% and 7.0% of all pregnancies, respectively. The predictors of HDP were age over 35 years (OR1.96, 95% CI 1.82–2.12; p < 0.001), lack of formal educational (OR 1.18, 95% CI 1.06–1.32; p = 0.002), primary level of education (OR 1.20, 95% CI 1.03–1.4; p < 0.002), nulliparity (OR 1.21, 95% CI 1.12–1.31; p < 0.001), grand‐multiparity (OR 1.36, 95%CI 1.21–1.52; p < 0.001), previous caesarean section (OR 1.26, 95%CI 1.15–1.38; p < 0.001) and previous miscarriage (OR 1.22, 95% CI 1.13–1.31; p < 0.001). Overall 3.7% of the patients with HDP died, with eclampsia having the highest case fatality rate of 27.9%. Stillbirth occurred in 11.9% of pregnancies with hypertensive disorders.ConclusionsHypertensive disorders in pregnancy are not uncommon in Nigeria. They are associated with adverse outcomes with over one‐quarter of women with eclampsia dying. The main predictors include older age, poor education, extremes of parity and previous CS or miscarriage. Maternal and perinatal outcomes are poor with about a quarter developing complications and about 1 in 10 having stillbirths.

AbstractObjectiveTo determine the feasibility of integrating Medicare Advantage (MA) admissions into the Centers for Medicare & Medicaid Services (CMS) hospital outcome measures through combining Medicare Advantage Organization (MAO) encounter‐ and hospital‐submitted inpatient claims.Data Sources and Study SettingBeneficiary enrollment data and inpatient claims from the Integrated Data Repository for 2018 Medicare discharges.Study DesignWe examined timeliness of MA claims, compared diagnosis and procedure codes for admissions with claims submitted both by the hospital and the MAO (overlapping claims), and compared demographic characteristics and principal diagnosis codes for admissions with overlapping claims versus admissions with a single claim.Data Collection/Extraction MethodsWe combined hospital‐ and MAO‐submitted claims to capture MA admissions from all hospitals and identified overlapping claims. For admissions with only an MAO‐submitted claim, we used provider history data to match the National Provider Identifier on the claim to the CMS Certification Number used for reporting purposes in CMS outcome measures.Principal FindingsAfter removing void and duplicate claims, identifying overlapped claims between the hospital‐ and MAO‐submitted datasets, restricting claims to acute care and critical access hospitals, and bundling same admission claims, we identified 5,078,611 MA admissions. Of these, 76.1% were submitted by both the hospital and MAO, 14.2% were submitted only by MAOs, and 9.7% were submitted only by hospitals. Nearly all (96.6%) hospital‐submitted claims were submitted within 3 months after a one‐year performance period, versus 85.2% of MAO‐submitted claims. Among the 3,864,524 admissions with overlapping claims, 98.9% shared the same principal diagnosis code between the two datasets, and 97.5% shared the same first procedure code.ConclusionsInpatient MA data are feasible for use in CMS claims‐based hospital outcome measures. We recommend prioritizing hospital‐submitted over MAO‐submitted claims for analyses. Monitoring, data audits, and ongoing policies to improve the quality of MA data are important approaches to address potential missing data and errors.
