Published: February 2024

Objective:
To report the developmental phase results of posterior rectus sheath hiatal flap augmentation (PoRSHA), a promising surgical innovation for large and recurrent paraesophageal hernias.

Background:
Durable hernia repair for large paraesophageal hernias continues to be a surgical challenge. PoRSHA addresses the challenges of current and historical approaches to complex paraesophageal hernias and demonstrates significant promise as a successful alternative approach.

Methods:
Using the IDEAL framework, we outline the technical modifications made over the first 27 consecutive cases using PoRSHA. Outcomes measured included hernia recurrence on routine imaging at 6 months and 2 years, development of a postoperative abdominal wall eventration and incidence of solid food dysphagia.

Results:
Twenty-seven patients at our single institution with type III (n=12), type IV (n=7) or recurrent (n=8) paraesophageal hernias underwent PoRSHA. Surgery was safely and successfully carried out in all cases. Stability of the technique was reached after 16 cases resulting in four main repair types. At an average follow up of 11 months, we observed no radiologic recurrences, no abdominal eventrations or hernias at the donor site and one patient with occasional solid food dysphagia that resolved with dilation.

Conclusions:
PoRSHA can not only be safely added to conventional hiatal hernia repair with appropriate training, but also demonstrates excellent short-term outcome. While the long-term durability with 5 year follow up is still needed, here we provide cautious optimism that PoRSHA may represent a novel solution to the longstanding high recurrence rates observed with current complex PEH repair.
High power electrostatic beam splitter for a proton beamline
Authors: Hartmann M. , Reggiani D. , Snuverink J. , Zhang H. , Seidel M. 
Published: February 2024

The High Intensity Proton Accelerator facility (HIPA) delivers a 590 MeV cw (50.6 MHz) proton beam with up to 1.4 MW beam power (2.4 mA) to spallation and meson production targets serving particle physics experiments and material research. The main accelerator is the ring cyclotron, an isochronous proton machine accelerating an injected 72 MeV beam to a final 590 MeV. A few meters downstream of the ring cyclotron, an electrostatic beam splitter was installed in the 1980s and originally designed to peel off from a 200  μA beam up to 20  μA (12 kW beam power). Future initiatives will also make use of the splitter. Specifically, as part of the Isotope and Muon Production using Advanced Cyclotron and Target technologies (IMPACT) upgrade project, Targeted Alpha Tumour Therapy and Other Oncological Solutions (TATTOOS), an online isotope separation facility will allow to produce promising radionuclides for diagnosis and therapy of cancer in quantities sufficient for clinical studies. The TATTOOS facility includes a dedicated beamline intended to operate at a beam intensity of 100  μA (60 kW beam power), requiring continuous splitting of the high-power main beam via the splitter. As a step forward toward reaching the desired beam intensity, a beam study was carried out to test the viability of the existing splitter for TATTOOS. The results of this study show that a record of 90  μA (53 kW beam power) was peeled off a horizontally and vertically enlarged beam by the splitter. The successful beam strategy employed during the study as well as the results of several key measurements are presented in this paper, with particular emphasis on diagnostic measurements. Additionally, to support the measurements, a computational model of the splitter has been implemented using Monte Carlo simulation tools, including realistic geometry, electrostatic fields, beam optics, and power deposition calculations. Overall, the results of this paper show that through the combination of beam measurements and simulations, the existing splitter can be used to reach the 100−μA beam intensity requirement for TATTOOS.

Theory of Tribovoltaics: Direct Current Generation at a
p
-
n
Semiconductor Interface
Authors: Willatzen Morten , Zhang Zhiwei , Wang Zhong Lin 
Published: February 2024

A simple theory of tribovoltaics is proposed by using a quantum mechanical model of energy release due to sliding-induced bonding between the surfaces of a p-doped semiconductor and a n-doped semiconductor. The energy release in forming a bond may lead to the excitation of electron-hole pairs at the p-n semiconductor interface if the released energy is higher than the effective band gap at the semiconductor interface. An expression for the generated current as a function of the relative sliding speed between the p and n sides is suggested and used to model current transport by solving the complete set of drift-diffusion equations with appropriate boundary and initial conditions. Analytical results are obtained and verified numerically using the finite-element-method software. It is shown that since the typical time period associated with periodic sliding is many orders of magnitude higher than the carrier lifetimes, the time-dependent variations in the electron and hole concentrations and the current density follow the time variation of the sliding speed. Since the electron-hole pair generation occurs near the semiconductor interface only, the current density is shown to be constant as a function of position even if the sliding speed changes in time.

Detection and localization of fault in DC microgrid using discrete Teager energy and generalized least square method
Authors: Barik Subrat Kumar , Nanda Smrutimayee , Samal Padarbinda , Senapati Rudranarayan 
Published: February 2024

Purpose
This paper aims to introduce a new fault protection scheme for microgrid DC networks with ring buses.

Design/methodology/approach
It is well recognized that the protection scheme in a DC ring bus microgrid becomes very complicated due to the bidirectional power flow. To provide reliable protection, the differential current signal is decomposed into several basic modes using adaptive variational mode decomposition (VMD). In this method, the mode number and the penalty factor are chosen optimally by using arithmetic optimization algorithm, yielding satisfactory decomposition results than the conventional VMD. Weighted Kurtosis index is used as the measurement index to select the sensitive mode, which is used to evaluate the discrete Teager energy (DTE) that indicates the occurrence of DC faults. For localizing cable faults, the current signals from the two ends are used on a sample-to-sample basis to formulate the state space matrix, which is solved by using generalized least squares approach. The proposed protection method is validated in MATLAB/SIMULINK by considering various test cases.

Findings
DTE is used to detect pole-pole and pole-ground fault and other disturbances such as high-impedance faults and series arc faults with a reduced detection time (10 ms) compared to some existing techniques.

Originality/value
Verification of this method is performed considering various test cases in MATLAB/SIMULINK platform yielding fast detection timings and accurate fault location.
A comprehensive review of delay analysis techniques for solving concurrent delays
Authors: Vo Huy Minh , Yang Jyh-Bin , Rangasamy Veerakumar 
Published: February 2024

PurposeConstruction projects commonly encounter complicated delay problems. Over the past few decades, numerous delay analysis methods (DAMs) have been developed. There is no consensus on whether existing DAMs effectively resolve delays, particularly in the case of complex concurrent delays. Thus, the primary objective of this study is to undertake a comprehensive and systematic literature review on concurrent delays, aiming to answer the following research question: Do existing delay analysis techniques deal with concurrent delays well?Design/methodology/approachThis study conducts a comprehensive review of concurrent delays by both bibliometric and systematic analysis of research publications published between 1982 and 2022 in the Web of Science (WoS) and Scopus databases. For quantitative analysis, a bibliometric mapping tool, the VOSviewer, was employed to analyze 68 selected publications to explore the co-occurrence of keywords, co-authorship and direct citation. Additionally, we conducted a qualitative analysis to answer the targeted research question, identify academic knowledge gaps and explore potential research directions for solving the theoretical and practical problems of concurrent delays.FindingsConcurrent delays are a critical aspect of delay claims. Despite DAMs developed by a limited number of research teams to tackle issues like concurrence, float consumption and the critical path in concurrent delay resolution, practitioners continue to face significant challenges. This study has successfully identified knowledge gaps in defining, identifying, analyzing and allocating liability for concurrent delays while offering promising directions for further research. These findings reveal the incompleteness of available DAMs for solving concurrent delays.Practical implicationsThe outcomes of this study are highly beneficial for practitioners and researchers. For practitioners, the discussions on the resolution process of concurrent delays in terms of identification, analysis and apportionment enable them to proactively address concurrent delays and lay the groundwork for preventing and resolving such issues in their construction projects. For researchers, five research directions, including advanced DAMs capable of solving concurrent delays, are proposed for reference.Originality/valueExisting research on DAMs lacks comprehensive coverage of concurrent delays. Through a scientometric review, it is evident that current DAMs do not deal with concurrent delays well. This review identifies critical knowledge gaps and offers insights into potential directions for future research.
A meta-analysis of antecedents and consequences of trust in the sharing economy
Authors: Jiang Jiang , Li Eldon Y. , Tang Li 
Published: February 2024

PurposeTrust plays a crucial role in overcoming uncertainty and reducing risks. Uncovering the trust mechanism in the sharing economy may enable sharing platforms to design more effective marketing strategies. However, existing studies have inconsistent conclusions on the trust mechanism in the sharing economy. Therefore, this study aims to investigate the antecedents and consequences of different dimensions of trust (trust in platform and trust in peers) in the sharing economy.Design/methodology/approachFirst, we conducted a meta-analysis of 57 related articles. We tested 13 antecedents of trust in platform (e.g. economic benefits, enjoyment, and information quality) and eight antecedents of trust in peers (e.g. offline service quality and providers’ reputation), as well as their consequences. Then, we conducted subgroup analyses to test the moderating effects of economic development level (Developed vs Developing), gender (Female-dominant vs Male-dominant), platform type (Accommodation vs Transportation), role type (Obtainers vs Providers), and uncertainty avoidance (Strong vs Weak).FindingsThe results confirm that all antecedents and consequences significantly affect trust in platform or peers to varying degrees. Moreover, trust in platform greatly enhances trust in peers. Besides, the results of the moderating effect analyses demonstrate the variability of antecedents and consequences of trust under different subgroups.Originality/valueThis paper provides a clear and holistic view of the trust mechanism in the sharing economy from an object-based trust perspective. The findings may offer insights into trust-building in the sharing economy.
On the nexus between code of business ethics, human resource supply chain management and corporate culture: evidence from MENA countries
Authors: AL-Shboul Moh'd Anwer 
Published: February 2024

Purpose
This paper aims to analyze the relationships between human resource supply chain management (HRSCM), corporate culture (CC) and the code of business ethics (CBE) in the MENA region.

Design/methodology/approach
In this study, the author adopted a quantitative approach through an online Google Form survey for the data-gathering process. All questionnaires were distributed to the manufacturing and service firms that are listed in the Chambers of the Industries of Jordan, Saudi Arabia, Morocco and Egypt in the MENA region using a simple random sampling method. About 567 usable and valid responses were retrieved out of 2,077 for analysis, representing a 27.3% response rate. The sample unit for analysis included all middle- and senior-level managers and employees within manufacturing and service firms. The conceptual model was tested using a hypothesis-testing deductive approach. The findings are based on covariance-based analysis and structural equation modeling (SEM) using PLS-SEM software. The author performed convergent validity and discriminant validity tests, and bootstrapping was also applied.

Findings
The empirical results display a significant and positive association between HRSCM and the CBE. The CC and the CBE tend to be positively and significantly related. Therefore, HRSCM can play a key role in boosting and applying the CBE in firms. For achieving the firm purposes, more attention to the HR personnel should be paid to implement the CBE. The high importance of the CBE becomes necessary for both the department and the firm.

Practical implications
Such results can provide insightful information for HR personnel, managers and leaders to encourage them to develop and maintain an effective corporate code of conduct within their organizations.

Originality/value
This paper tries to explore the linkages between HRSCM, CC and CBE in the Middle East region due to the lack of research available that analyzes the relationship between them. Not only that, but it also offers great implications for Middle Eastern businesses.

Published: February 2024

Purpose
The China’s Belt and Road Initiative (BRI, hereafter) has reenergized the Silk Road concept, with most literature focusing on the political and economic effects of the BRI. While certain aspects of the Digital Silk Road (DSR), digital component of BRI, have been researched, much less focus has been placed on the technological development, tech transfer and information diffusion aspects of the BRI. The aim of this study is to investigate the opportunities, issues and critiques that have arisen as a result of the Belt and Road Initiative’s implications on innovation, knowledge transfer and dissemination.

Design/methodology/approach
Research in its nature is descriptive. Literature reviews are a significant part of the development of a field. Therefore, secondary sources were considered.

Findings
The literature and the study have highlighted several opportunities, problems and criticism that decision-makers and the relevant agencies and institutions should take into account when deciding how to move forward with BRI and its digital component DSR.

Originality/value
This paper contributes to the research literature on BRI and its subset DSR’s impacts on innovation, knowledge transfer and information diffusion. In fact, the DSR’s primary aim is to strengthen international cooperation in the digital economy. Furthermore, digital platforms now play a significant role in global trade, emphasizing the necessity of DSR.

Published: February 2024

PurposeRecently, autonomous vehicles (AV) acceptance has been studied intensively. This paper aims to map and analyze the bibliometric characteristics of AV acceptance literature. Furthermore, this research aims to identify research gaps and propose future research opportunities.Design/methodology/approachThe bibliometric analysis was performed. Scopus database was used as the source of the literature. This study selected and analyzed 297 AV acceptance papers. The performance and science mapping analysis were performed.FindingsThe developed countries tended to dominate the topic. The publication outlet tended to be in transportation or technology journals. There were four research themes in existing literature. Technology acceptance model (TAM) and UTAUT2 tended to be used for explaining AV acceptance. AV acceptance studies tended to use two types of psychological concepts for understanding AV acceptance, namely risk related concepts and functional utilitarian benefit related concepts. In the context of research design, quantitative approach tended to be used. Self-driving feature was the most exploited feature of AV in the existing literature. Three research gaps were mapped and future research opportunities were proposed.Practical implicationsThis paper provided a comprehensive information that allowed scientists to develop future research on AV acceptance.Originality/valueThere is lack of paper that discussed the bibliometric characteristics of AV acceptance literature. This paper fulfilled the gap.
Against book enclosures: Moving towards more diverse, humane and accessible book publishing
Authors: Batterbury Simon P. J. , Pia Andrea E. , Wielander Gerda , Loubere Nicholas 
Published: February 2024

AbstractMatthew Gandy's Commentary in Area (2023) criticised the decision of the national funder UKRI to mandate that all books resulting from the research that it funds must be published open access (OA) from 2024. This raises many issues of importance to geographers. We argue that scholars in the discipline need to fight for affordable and ethically produced OA books, not ‘legacy’ modes of publishing. In particular, books produced by scholar‐led OA presses will not harm the reputation of departments or individual scholars, and they also have the potential to reduce significant financial barriers to accessing books across the globe. A more powerful critique must be to challenge the continued ‘enclosure’ of books, and the denial of OA by academic publishers and university presses.

Published: February 2024

Clinical research has not been able to establish whether the differences between first‐ and second‐generation BCR‐ABL 1 kinase inhibitors are clinically relevant with regard to outcome. In the study by Alcazer et al., a relevant difference seems to emerge—paradoxically in the absence of the drugs—as demonstrated by differences in the relapse kinetics after cessation of therapy.Commentary on: Alcazer et al.

ObjectiveTo evaluate the prognostic value of T1 substaging in patients treated with bacillus Calmette‐Guérin (BCG) or immediate radical cystectomy (iRC).Materials and MethodsWe performed an institutional review board‐approved retrospective study analysing non‐muscle‐invasive bladder cancer (NMIBC) patients with pT1 disease treated with either BCG or iRC between 2000 and 2020. Lamina propria (LP) invasion characteristics were extracted from the pathology report. The Kaplan–Meier method was used to calculate overall survival (OS), cancer‐specific survival (CSS) and metastasis‐free survival (MFS). Multivariable Cox models were used to determine the association between progression‐free survival (PFS) and characteristics in the BCG cohort. A logistic regression model explored the relationship between T1 substaging and upstaging to >pT2 at iRC.ResultsA total of 411 T1 high‐grade patients were identified. LP invasion characteristics were as follows: not specified: 115 (28%); focal/superficial (F/S): 147 (35.8%); and extensive/multifocal (E/M): 149 (36.2%). Overall, 303 patients (73.7%) received BCG, and 108 patients (26.3%) underwent iRC. The median (interquartile range) follow‐up was 53 (32–96) months. Patients with E/M LP invasion were significantly more likely to undergo iRC (34% vs. 19%; P = 0.003). Patients with E/M LP invasion showed poorer MFS and CSS compared to those with F/S LP invasion when treated with BCG but not when treated with iRC. Among BCG‐treated patients, progression occurred in 41 patients and E/M LP invasion was independently associated with progression after BCG (hazard ratio 5.3, 95% confidence interval [CI] 2.2–13.1; P < 0.001). T1 substaging was not associated with upstaging at RC (odds ratio 3.15, 95% CI 0.82–12.12; P = 0.095).ConclusionsExtensive/multifocal LP invasion was associated with poor PFS, MFS and CSS in patients treated with BCG. T1 substaging provides valuable prognostic information and should be reported in pathology reports.
