An extended variational iteration method for fractional BVPs encountered in engineering applications
Authors: Khuri Suheil , Assadi Reem 
Published: April 2023

Purpose
The purpose of this paper is to find approximate solutions for a general class of fractional order boundary value problems that arise in engineering applications.

Design/methodology/approach
A newly developed semi-analytical scheme will be applied to find approximate solutions for fractional order boundary value problems. The technique is regarded as an extension of the well-established variation iteration method, which was originally proposed for initial value problems, to cover a class of boundary value problems.

Findings
It has been demonstrated that the method yields approximations that are extremely accurate and have uniform distributions of error throughout their domain. The numerical examples confirm the method’s validity and relatively fast convergence.

Originality/value
The generalized variational iteration method that is presented in this study is a novel strategy that can handle fractional boundary value problem more effectively than the classical variational iteration method, which was designed for initial value problems.
The black sheep in hospitality organizations: how and when coworker service sabotage hinders employee service creativity
Authors: Lyu Yijing , Zhu Hong , Huang Emily G. , Chen Yuanyi 
Published: April 2023

Purpose
The purpose of this paper is to propose a research model in which coworker service sabotage influences hospitality employees’ service creativity via work engagement. It also aims to test the moderating effect of sensitivity to the interpersonal mistreatment of others (SIMO).

Design/methodology/approach
A time-lagged questionnaire study was performed in hotels in China. The hypotheses were tested via hierarchical multiple regression.

Findings
Coworker service sabotage is indirectly associated with hospitality employees’ service creativity via work engagement. The trait of SIMO buffers the harmful effect of coworker service sabotage.

Research limitations/implications
Although our research design helps mitigate common method bias, it could still exist. Other coworker behaviors that might influence employees were not included in this research. The findings may also be biased due to the restricted sample from China.

Practical implications
Hospitality organizations should take measures to curb service sabotage. Organizations could also provide supportive resources to suppress the negative impacts of coworker service sabotage. Moreover, organizations should motivate those low in SIMO to care more about customers.

Originality/value
The research takes the lead in investigating the outcomes of service sabotage from a third-party perspective. Work engagement is identified as the mechanism for transmitting the impact of coworker service sabotage to employees. Moreover, a new moderator that attenuates the negative effects of coworker service sabotage is found.
Collaborating in a centralized governance mechanism: structure and fragmentation of large-scale response coordination during the 2018 Typhoon Mangkhut in Shenzhen
Authors: Wang Xiao 
Published: April 2023

PurposeThis paper aims to examine a large-scale typhoon response coordination, focusing on the emergency collaborative network (ECN) configuration and structural properties that characterized the 2018 Typhoon Mangkhut response operations in Shenzhen, China.Design/methodology/approachThe response coordination of Typhoon Mangkhut was operationalized as a Shenzhen-based ECN established upon a six-week observation. A systematic content analysis of publicly available government documents and newspaper articles was conducted to identify participating organizations and interorganizational relationships built and sustained during and immediately after the disaster. Social network metrics at levels of the node, subgroup of nodes and whole network were utilized to examine network capacity, network homophily and network performance, respectively.FindingsResults of the centrality analysis demonstrate that government agencies at municipal and district/county levels took central network positions while private and non-profit organizations were mostly positioned at the network periphery. The blocking analysis points to a salient homophily effect that participating organizations sharing similar attributes were more likely to connect with each other. A further investigation of whole network metrics and the small-world index reveals the highly fragmented and discontinued features of ECN, which may result in unsystematic coordination among organizational actors.Originality/valueThis paper is distinctive in examining the coordination structure among response organizations embedded in a centralized and monocentric governance system and, more importantly, how the structural characteristics can differ from that evidenced in a more decentralized and polycentric system.

Authors: Nautiyal Shreyasi , Pathak Prachi 
Published: April 2023

Purpose
Resilience has evolved as a dynamic process in the entrepreneurship field. The purpose of this paper is to outline a comprehensive structure to analyse the patterns and trends in the publications of the existing literature at the junction of entrepreneurship and resilience. With the help of bibliometric and network analysis, this study offers insights into the topic that have not been evaluated and assessed by previous reviews.

Design/methodology/approach
A computerised search of 104 papers was performed using the Scopus database, and graphical visualisation of the bibliographic material was developed using VOSviewer software.

Findings
This comprehensive bibliometric mapping helps in the graphical visualisation of publication evolution of the domain along with identifying present research trends and possible future directions. There is not much collaborative research in the field, as most prolific thinkers work in isolation or in pairs. Hence, there are limited publications in top-rated journals. Future researchers need to work collaboratively to produce high-quality papers. Developed nations make a sound contribution to the field. The exact significance of resilience in entrepreneurship is yet to be determined due to a wide variety of themes that reflect the multi-disciplinary nature of the domain.

Originality/value
Uncovering the trends and developments of the field, this study provides a global perspective and potential themes lying at the junction of resilience and entrepreneurship. Hence, this study provides a robust roadmap for future researchers interested in this area.
Lateral torsional buckling behaviour of tapered steel section with web opening – finite element analysis
Authors: De’nan Fatimah , Hashim Nor Salwani , Siew Ting Ngo 
Published: April 2023

Purpose
Recently, this steel section has found increasing popularity in residential, industrial and commercial buildings with their high load-carrying capacity due to the nature of high strength to weight ratio properties. However, the rise on the price of steel section should be more emphasized; therefore, the optimization in steel section design is needed to overcome the issue of material cost. As such, tapered steel sections save on material use, while the introduction of web openings allows the placement of mechanical and electrical services, plumbing and also aesthetic design considerations.

Design/methodology/approach
The purpose of this study is to investigate the lateral torsional buckling behavior of a tapered steel section with an ellipse-shaped opening by analyzing its structural parameters. To achieve this, the finite element analysis (FEA) of the section is modeled using LUSAS software, which allows for a detailed analysis of the section's behavior under varying loads and conditions. It involves the variation in web opening size, opening layout, opening rotation angle and the tapering ratio. Eigenvalue buckling analysis is adopted to know the parametric effects of each 108 model. The size of opening varies from 0.2 to 0.5 d of the total depth where the opening located. There are three type of layouts applied in this study, which are the layouts A, B and C. There are three types of rotation angles for the ellipse-shaped opening, including the non-rotated vertical opening and two additional types formed by rotating the opening 45 degrees clockwise and counterclockwise around the center-point of the ellipse. A fixed-free boundary condition was applied, resulting in a simulation of a cantilever beam. The models are fixed at one end with a larger depth, and free at the other end with a smaller depth. Loading condition is an application of 10 kN/m uniform distributed load in the direction of gravity along the mid-span of the top flange.

Findings
It is observed that the model 82 with Layout A, tapering ratio 0.3, opening size 0.5 d and opening rotated in 45 degree anti-clockwise direction results in the highest structural efficiency among the 108 models. Therefore, the buckling moment of model 82 is 1,013.08 kNm with structural efficiency of 481.26, which shows an increase of 3.17% compared to the controlled model.

Originality/value
The FEA results shows a significant increase in ductility and stiffness of the tapered steel section with elipse shape opening and consequently changes in the behaviour of yield point.

Abstract

Many temperate grasses are both hyper‐accumulators of silicon (Si) and hosts of Epichloë fungal endophytes, functional traits which may alleviate environmental stresses such as herbivore attack. Si accumulation and endophyte infection may operate synergistically, but this has not been tested in a field setting, nor in the context of changing environmental conditions. Predicted increases in atmospheric CO2 concentrations can affect both Si accumulation and endophyte function, but these have not been studied in combination.

We investigated how elevated atmospheric CO2 (eCO2), Si supplementation, endophyte‐presence and insect herbivory impacted plant growth, stoichiometry (C, N, P and Si), leaf gas exchange (rates of photosynthesis, stomatal conductance, transpiration rates) and endophyte production of anti‐herbivore defences (alkaloids) of an important pasture grass (tall fescue; Lolium arundinaceum) in the field.

eCO2 and Si supplementation increased shoot biomass (+52% and +31%, respectively), whereas herbivory reduced shoot biomass by at least 35% and induced Si accumulation by 24%. Shoot Si concentrations, in contrast, decreased by 17%–21% under eCO2. Si supplementation and herbivory reduced shoot C concentrations. eCO2 reduced shoot N concentrations which led to increased shoot C:N ratios. Overall, shoot P concentrations were 26% lower in endophytic plants compared to non‐endophytic plants, potentially due to decreased mass flow (i.e. observed reductions in stomatal conductance and transpiration). Alkaloid production was not discernibly affected by any experimental treatment. The negative impacts of endophytes on P uptake were particularly strong under eCO2.

We show that eCO2 and insect herbivory reduce and promote Si accumulation, respectively, incorporating some field conditions for the first time. This indicates that these drivers operate in a more realistic ecological context than previously demonstrated. Reduced uptake of P in endophytic plants may adversely affect plant productivity in the future, particularly if increased demand for P due to improved plant growth under eCO2 cannot be met.

R&D subsidy and output subsidy in a duopoly: The role of technology spillover and R&D budget
Authors: Gao Xing , Wang Xifan , Zhong Weijun , Wang Ying 
Published: April 2023

AbstractTechnology spillover and research and development (R&D) budget are relevant on government subsidies that aim at improving social welfare through enhancing R&D incentives of firms. However, there has not been related literature considering these two factors. To fill this gap, this paper examines the effect of technology spillover and R&D budget on R&D competition of duopolistic firms and government subsidies by constructing a game‐theoretic model. We find that while each firm's profit sometimes increases with R&D budget for low coefficient of technology spillover, this profit may decrease with R&D budget for high coefficient of technology spillover due to the intensified R&D competition. We show that when both R&D budget and the coefficient of technology spillover remain high, R&D subsidy leads to higher social welfare than output subsidy and otherwise R&D subsidy results in lower social welfare.
Welfare brokers and European Union migrants' access to social protection
Authors: Voivozeanu Alexandra , Lafleur Jean‐Michel 
Published: April 2023

AbstractIn spite of the existence of an extensive national and supranational legal framework, European Union (EU) citizens who exercise their right to freedom of movement to work in another Member State face numerous hurdles in accessing social protection. While recent scholarship on street‐level bureaucracy and on migration and welfare has shed light on the role of discretion and stereotypes in access to rights, little is known about the processes through which such hurdles are overcome. In this article, we focus on a specific strategy which is the recourse to what we call “welfare brokers”. These actors offer assistance to EU migrants to overcome specific cross‐border administrative challenges in the area of social protection that derive from their use of the right to freedom of movement. Relying on qualitative data collected with brokers and Romanian migrants working in Germany, the article also demonstrates that welfare brokers attempt to transform the norms, bureaucratic practices and representations that condition access to these entitlements. The article concludes by underlining how the existence of a brokerage industry is a sign of existing inequalities in the exercise of freedom of movement within the EU.
Can latent fingerprint disclose the sex of the donor? A preliminary test study using GC–MS analysis of latent fingerprints
Authors: Primeau Charlotte , Dzetkuličová Veronika , Shepherd Tom 
Published: April 2023

AbstractWhile fingerprints are a highly used means of identification, not every fingerprint left behind on a potential crime scene can be used for identification purposes. In some cases, the fingerprint may be smudged, partially preserved or overlapping with other prints hence distorting the ridge pattern and may therefore be not appropriate for identification. Further, fingermark residue yields a very low abundance of genetic material for DNA analysis. In such cases, the fingermark may be used to retrieve basic donor information such as sex. The focus of this paper was to assess the possibility of differentiating between the sexes of the donor of latent fingermarks. Analytical method was GC–MS analysis of the chemical compounds of latent fingermarks using 22 male and 22 female donors. Results showed 44 identified compounds. Two alcohols, octadecanol C18 and eicosanol C20, were found to show a difference that was statistically significant between male and female donors. There is also some evidence for the possibility of distinguishing sex of the fingermark donor based on the distribution of branched chain fatty acids, as free compounds or esterified in wax esters.

Published: April 2023

AbstractGiven the wide diversity of data services provided to national water management agencies, the Group on Earth Observations (GEO) in collaboration with the Committee on Earth Observation Satellites (CEOS) developed the approach described in the report, Implementing the GEOSS Water Strategy—From Observations to Decisions to develop more coherent and equitable data services for water management through the use of Earth observations. Among other water resource issues, it recognized the need to enhance data‐enriched water management services to support decision making related to drought monitoring, flood warning, tracking and improving sustainable development and monitoring and ameliorating the impacts of climate change. Needs associated with the Strategy's four themes: improved data acquisition for essential water variables, research and product development, interoperability and coordination, and capacity development and decision support, are reviewed. Responses to the recommendations have been undertaken by GEO, led by its Global Water Sustainability (GEOGloWS) initiative which includes NASA contributions, CEOS, and the Global Terrestrial Network for Hydrology (GTN‐H). Progress on the themes is reviewed and benefits of these developments for international and US water management are identified. The commentary concludes with a summary of what has been achieved, what remains to be done, and the priority focus areas for implementation in the final year of the Strategy.

AbstractTo explore the relationship of systemic lupus erythematosus (SLE) and subsequent glaucoma incidence. Patients with SLE were defined as those newly diagnosed by International Classification of Diseases, 9th Revision, Clinical Modification (ICD‐9‐CM) code 710.0 in at least 3 outpatient visits or 1 hospitalization during 2000–2012 by using the National Health Insurance Research Database. We selected a non‐SLE comparison cohort at a 1:1 ratio by propensity score matching on age, gender, index date, comorbidities and medications. We identified outcome as the incident glaucoma in patients with SLE. Multivariate Cox regression analysis was used to calculate the adjusted hazard ratio (aHR) in 2 groups. Kaplan‐ Meier analysis was performed to estimate the cumulative incidence rate between both groups. There were 1743 patients who were included in the SLE group and non‐SLE group. The aHR of glaucoma was 1.56 (95% CI = 1.03–2.36) in the SLE group, compared to non‐SLE controls. Subgroup analysis showed that SLE patients present greater risk of glaucoma, especially in males (aHR = 3.76; 95% CI, 1.5–9.42), and the P for interaction between gender and risk of glaucoma was 0.026. This cohort study showed that patients with SLE have 1.56‐fold risk of glaucoma development. Gender acted as an effect modifier between SLE and the risk of new‐onset glaucoma.

Published: April 2023

AbstractDecreased DJ‐1 protein impairs antioxidative activity of neurons and plays an important role in the occurrence of Parkinson's disease (PD). We have previously identified hsa‐miR‐4639‐5p as the post‐transcriptional regulator of DJ‐1. Increased expression of hsa‐miR‐4639‐5p reduced DJ‐1 level and increased oxidative stress leading to neuronal death. Therefore, understanding the detailed mechanisms by which hsa‐miR‐4639‐5p expression is regulated will not only facilitate diagnosis but also inform the pathogenesis of PD. We examined hsa‐miR‐4639‐5 in either the plasma or exosomes derived from the central nervous system (CNS) neurons of PD patients and healthy controls. We showed that CNS‐derived exosomes gave rise to the increased plasma hsa‐miR‐4639‐5p in PD patients, pointing to hsa‐miR‐4639‐5p dysregulation in the brain of PD patients. Using a dual‐luciferase assay and a CRISPR‐Cas9 system, we identified a core promoter of hsa‐miR‐4639 (−560 to −275 upstream the transcriptional starting site) of the gene for myosin regulatory light chain interacting protein. A polymorphism in the core promoter (rs760632 G>A) could enhance hsa‐miR‐4639‐5p expression and increase PD risk. Furthermore, using MethylTarget™ assay, ChIP‐qPCR, and specific inhibitors, we demonstrated that hsa‐miR4639‐5p expression was regulated by HDAC11‐mediated histone acetylation but not DNA methylation/demethylation. Taken together, our study provides evidence that hsa‐miR‐4639‐5p is a potential diagnostic marker and therapeutic target for PD. Interventions targeting hsa‐miR‐4639‐5p might represent a novel therapy to promote healthy aging.

AbstractObjectivesTransfusion of a high ratio of plasma to packed red blood cells (PRBCs), to treat or prevent acute traumatic coagulopathy, has been associated with survival after major trauma. However, the effect of prehospital plasma on patient outcomes has been inconsistent. The aim of this pilot trial was to assess the feasibility of transfusing freeze‐dried plasma with red blood cells (RBCs) using a randomized controlled design in an Australian aeromedical prehospital setting.MethodsPatients attended by helicopter emergency medical service (HEMS) paramedics with suspected critical bleeding after trauma managed with prehospital RBCs were randomized to receive 2 units of freeze‐dried plasma (Lyoplas N‐w) or standard care (no plasma). The primary outcome was the proportion of eligible patients enrolled and provided the intervention. Secondary outcomes included preliminary data on effectiveness, including mortality censored at 24 h and at hospital discharge, and adverse events.ResultsDuring the study period of June 1 to October 31, 2022, there were 25 eligible patients, of whom 20 (80%) were enrolled in the trial and 19 (76%) received the allocated intervention. Median time from randomization to hospital arrival was 92.5 min (IQR 68–101.5 min). Mortality may have been lower in the freeze‐dried plasma group at 24 h (RR 0.24, 95% CI 0.03–1.73) and at hospital discharge (RR 0.73, 95% CI 0.24–2.27). No serious adverse events related to the trial interventions were reported.ConclusionsThis first reported experience of freeze‐dried plasma use in Australia suggests prehospital administration is feasible. Given longer prehospital times typically associated with HEMS attendance, there is potential clinical benefit from this intervention and rationale for a definitive trial.
