Authors: Lopez-Torres Gabriela Citlalli , Montejano-García Salomón , Alvarez-Torres Francisco Javier , Perez-Ramos Marcelo de Jesus 
Published: August 2021

Purpose
This paper aims to present a systematic review of the literature on sustainability for the competitiveness of firms to identify the state of the art, significant discussions and new research directions. Recently, due to the negative impacts that traditional and unsustainable practices of companies have caused the Planet (e.g. climate change, sanitary crisis), national and international research urgently calls for the assessment of sustainable practices in firms. However, progress seems slow due to a poor understanding of the necessary changes that companies must make in their specific reality. Competitiveness has remained as firms’ primary strategy to endure. Some have associated sustainability with an increment of costs, sometimes with a negative impact on its competitiveness. Sometimes generating oppositions from stakeholder and institutions regulations, it is important to explore how these behaviors and dynamics of this relationship between sustainability and competitiveness affect the pursued transition to sustainability.

Design/methodology/approach
A systematic review of the literature, which is a scientific tool, is used in this research. It allows reliably and accurately analyzing and constructing conclusions from a broad database. The search was leaked over the 10 years, from 2010 to 2019. As a basis, 182 scientific articles were identified and revised based on methodology selection criteria and 51 articles were revised in detail.

Findings
This paper identifies critical variables analyzed in the selected articles, sustainability strategies for competitiveness, strategies for sustainability, organizational aspects for sustainability and competitiveness, measurement of sustainability, models, moderating factors for sustainability and new future research directions.

Originality/value
This paper presents state of art about sustainability for competitiveness and identifying key themes and future research directions.

Authors: Jin Yuran , Campbell Robert , Tang Jinhuan , Ji Huisheng , Song Danrong , Liu Xiaoqin 
Published: August 2021

Purpose
Global economic growth provides new opportunities for the development of clothing enterprises, but at the same time, the rapid growth of clothing customization demand and the gradual increase of clothing costs also pose new challenges for the development of clothing enterprises. In this context, 3D printing technology is injecting new vitality and providing a new development direction for the vigorous development of clothing enterprises. However, with the application of 3D printing technology, more and more clothing enterprises are facing the problem of business model innovation. In view of the lack of relevant research, it is necessary to carry out exploratory research on this issue.

Design/methodology/approach
The business model canvas method was adopted to design business model for clothing enterprises using 3D printing. The simulation model of the designed business model was constructed by a system dynamics method, and the application of the designed business model was analysed by a scenario simulation.

Findings
Mass selective customization-centralized manufacturing (MSC-CM) business model was constructed for clothing enterprises using 3D printing, and a static display was carried out using the BMC method. A dynamic simulation model of the MSC-CM business model was constructed. The future scenario of clothing enterprises using 3D printing was developed, and a simulated enterprise was analysed. The results show that the MSC-CM business model has a good application value. The simulation model of the MSC-CM business model performs the function of a business strategy experiment platform and also has a good practical application value.

Research limitations/implications
The MSC-CM business model is only a typical business model for clothing enterprises using 3D printing. It is necessary to further develop other business models, and some elements of the MSC-CM business model need to be further improved. In addition, the MSC-CM business model simulation uses a general model, which is not suitable for all clothing enterprises using 3D printing. When the model is applied, the relevant enterprises can further adjust and optimize it, thereby improving the validity of the simulation model.

Originality/value
To the best of the authors’ knowledge, this is the first paper on the MSC-CM business model for garment enterprises using 3D printing. Secondly, it is the first time that the business model of clothing enterprises using 3D printing has been simulated. In particular, the proposed business model simulation provides the possibility for testing the business strategy of clothing enterprises using 3D printing. In addition, a positive attempt has been made in the collaborative research of using both a static display business model and a dynamic simulation business model.

Published: August 2021

Purpose
When a railway emergency occurs, it often leads to unexpected consequences, especially for trains of higher speed and larger passenger flow. Therefore, the railway emergency plan, a pre-established plan to deal with emergencies, plays an important role in reducing injuries and losses. However, the existing railway emergency plans remain as plain-text documents, requiring lots of manual work to capture the important regulations. This paper aims to propose a visualized, formal and digital railway emergency plan modeling method based on hierarchical timed Petri net (HTPN), which is also of better interpretability.

Design/methodology/approach
First, the general railway emergency plan was analyzed. Second, the HTPN-based framework model for the general railway emergency plan was proposed. Then, the instantiated model of electric multiple units rescue emergency plan was built by ExSpect, a Petri net simulation tool.

Findings
The experiments show that the proposed model is more digital and of better readability, visualization and performability, and, meanwhile, can generally conform to the practice well, offering a promising reference for future analysis of the optimization of railway emergency plans.

Originality/value
This study offers a promising reference for future analysis of the optimization of railway emergency plans.

Authors: Heng Elwin , Abdullah Mohd Zulkifly 
Published: August 2021

PurposeThis paper focuses on the fluid-structure interaction (FSI) analysis of moisture induced stress for the flip chip ball grid array (FCBGA) package with hydrophobic and hydrophilic materials during the reflow soldering process. The purpose of this paper is to analyze the influence of moisture concentration and FCBGA with hydrophobic material on induced pressure and stress in the package at varies times.Design/methodology/approachThe present study analyzed the warpage deformation during the reflow process via visual inspection machine (complied to Joint Electron Device Engineering Council standard) and FSI simulation by using ANSYS/FLUENT package. The direct concentration approach is used to model moisture diffusion and ANSYS is used to predict the Von-Misses stress. Models of Test Vehicle 1 (similar to Xieet al., 2009b) and Test Vehicle 2 (FCBGA package) with the combination of hydrophobic and hydrophilic materials are performed. The simulation for different moisture concentrations with reflows process time has been conducted.FindingsThe results from the mechanical reliability study indicate that the FSI analysis is found to be in good agreement with the published study and acceptable agreement with the experimental result. The maximum Von-Misses stress induced by the moisture significantly increased on FCBGA with hydrophobic material compared to FCBGA with a hydrophilic material. The presence of hydrophobic material that hinders the moisture desorption process. The analysis also illustrated the moisture could very possibly reside in electronic packaging and developed beyond saturated vapor into superheated vapor or compressed liquid, which exposed electronic packaging to higher stresses.Practical implicationsThe findings provide valuable guidelines and references to engineers and packaging designers during the reflow soldering process in the microelectronics industry.Originality/valueStudies on the influence of moisture concentration and hydrophobic material are still limited and studies on FCBGA package warpage under reflow process involving the effect of hydrophobic and hydrophilic materials are rarely reported. Thus, this study is important to effectively bridge the research gap and yield appropriate guidelines in the microelectronics industry.

Authors: Khalid Sumeet , Khan Faisal , Ahmad Zahoor , Ullah Basharat 
Published: August 2021

Purpose
For compactness and ease in assembling, a novel miniature size tubular moving magnet linear oscillating actuator (MT-MMLOA) design for miniature linear compressor application is proposed in this paper.

Design/methodology/approach
This MT-MMLOA design possesses a modular C-core stator structure having separation at the middle. Axially magnetized tubular permanent magnets are accommodated on the mover. To improve the output parameters of the linear oscillating actuators (LOA), all the design parameters are optimized using a parametric sweep. Finite element analysis of the proposed design is performed to examine the magnetic flux density as well as thrust force under both static and dynamic analysis within the intended stroke range.

Findings
Compared to conventional LOA for miniature compressors, the motor constant of the proposed LOA is 37 N/A that is 85% greater while keeping the same size of LOA. Permanent magnet volume used in the investigated topology of LOA is 26% reduced. Additionally, the overall volume of the machine is 10.3% decreased. Furthermore, the proposed topology is simple, inexpensive and easy to manufacture.

Originality/value
Electromagnetic performance comparison with different topologies proposed earlier in literature is carried out to prove the performance superiority of the proposed design.

Published: August 2021

SummaryResistance to inhibitors of cholinesterase 8 (Ric8) is a conserved guanine nucleotide exchange factor that is involved in the regulation of G‐protein signalling in filamentous fungi. Here, we characterized an orthologous Ric8 (AoRic8) in Arthrobotrys oligospora by multi‐omics analyses. The Aoric8 deletion (ΔAoric8) mutants lost an ability to produce traps essential for nematode predation, accompanied by a marked reduction in cAMP level. Yeast two‐hybrid assay revealed that AoRic8 interacted with G‐protein subunit Gα1. Moreover, the mutants were compromised in mycelia growth, conidiation, stress resistance, endocytosis, cellular components and intrahyphal hyphae. Revealed by transcriptomic analysis differentially upregulated genes in the absence of Aoric8 were involved in cell cycle, DNA replication and recombination during trap formation while downregulated genes were primarily involved in organelles, carbohydrate metabolism and amino acid metabolism. Metabolomic analysis showed that many compounds were markedly downregulated in ΔAoric8 mutants versus the wild‐type strain. Our results demonstrated a crucial role for AoRic8 in the fungal growth, environmental adaption and nematode predation through control of cell cycle, organelle and secondary metabolism by G‐protein signalling.

Published: August 2021

AbstractAdvances in the digital world have attracted the attention of many researchers in terms of developing digital forensics. Using machine learning methods for print source identification is one of the developing areas in the field of digital forensics. In this paper, a new method is presented for printer source identification by modeling the primary Local Binary Pattern (LBP) features in the total variable printer space and extracting the secondary features based on the joint factor analysis. Only one low‐dimensional i‐vector feature is employed for each document image without using any optical character recognition (OCR) algorithm or similar processes. This property eliminates the requirement for the majority voting algorithm and reduces the computational cost of the classification process. Furthermore, the proposed algorithm is not limited to a specific language or character set. The capabilities of the proposed method in extracting useful discriminant information from the sparse print shadow texture are revealed through simulation. The simulation results showed that the proposed algorithm obtained the accuracy of 98.48% by refining the basic features of LBP, which is comparable to the results of the state‐of‐the‐art approaches in this field.

Published: August 2021

AbstractIdentifying the source of body fluids found at a crime scene is an essential forensic step. Some methods based on DNA methylation played significant role in body fluids identification. Since DNA methylation is related to multiple factors, such as race, age, and diseases, it is necessary to know the methylation profile of a given population. In this study, we tested 19 body fluid‐specific methylation markers in a Chinese Han population. A novel multiplex assay system based on the selected markers with smaller variation in methylation and stronger tissue‐specific methylation were developed for the identification of body fluids. The multiplex assay were tested in 265 body fluid samples. A random forest model was established to predict the tissue source based on the methylation data of the 10 markers. The multiplex assay was evaluated by testing the sensitivity, the mixtures, and old samples. For the result, the novel multiplex assay based on 10 selected methylation markers presented good methylation profiles in all tested samples. The random forest model worked extremely well in predicting the source of body fluids, with an accuracy of 100% and 97.5% in training data and test data, respectively. The multiplex assay could accurately predict the tissue source from 0.5 ng genomic DNA, six‐months‐old samples and distinguish the minor component from a mixture of two components. Our results indicated that the methylation multiplex assay and the random forest model could provide a convenient tool for forensic practitioners in body fluid identification.

Published: August 2021

AbstractObjectiveLimited English proficiency (LEP) is a risk factor for health care inequity and an important focus for improving communication and care quality. This study examines the association between LEP and pediatric emergency department (ED) revisits.MethodsThis was a retrospective, cross‐sectional study of patients 0 to 21 years old discharged home after an initial visit from an academic, tertiary care pediatric ED from January 1, 2017, to June 30, 2018. We calculated rates of ED revisits within 72 h resulting in discharge or hospitalization and assessed rate differences between LEP and English‐proficient (EP) patients. Multivariable logistic regression models examined the association between revisits and LEP status controlling for age, race, ethnicity, triage acuity, clinical complexity, and ED arrival time. Sensitivity models including insurance were also conducted.ResultsThere were 63,601 index visits in the study period; 12,986 (20%) were by patients with LEP. There were 2,387 (3.8%) revisits within 72 h of initial ED visit. Among LEP and EP patient visits, there were 4.53 and 3.55 revisits/100 initial ED visits, respectively (rate difference = 0.97, 95% confidence interval [CI] = 0.58 to 1.37). In the multivariable analyses, LEP was associated with increased odds of revisits resulting in discharge (odds ratio [OR] = 1.15, 95% CI = 1.01 to 1.30) and in hospitalization (OR = 1.28, 95% CI = 1.03 to 1.58). Sensitivity analyses additionally adjusting for insurance status attenuated these results.ConclusionsThese results suggest that LEP was associated with increased pediatric ED revisits. Improved understanding of language barrier effects on clinical care is important for decreasing health care disparities in the ED.
FGF5 missense mutation is associated with dromedary hair length variation
Authors: Maraqa T. , Alhajeri B. H. , Alhaddad H. 
Published: August 2021

SummarySeveral FGF5 mutations are associated with hair length variation in many domestic animals, including New World camelids. The dromedary was investigated in the present study with breeds exhibiting marked variations in hair length. This study aimed to: (1) identify the molecular variation(s) in the three exons of FGF5 of a diverse group of breeds (Mejaheem, Shaele, Sofor, Waddah and Omani; n = 28); (2) examine the association of the identified variants with hair length; (3) validate the association via genotyping the polymorphism in a large population of diverse camels (n = 113); and (4) test the segregation of the identified variant with hair length in a pedigree. A non‐synonymous mutation (c.779 C > T) was identified that changes the amino acid from proline to leucine and was found to be associated with different hair length in dromedaries. The variants at c.779 displayed a co‐dominance mode of inheritance and three hair length phenotypes: short (C/C), intermediate (C/T) and long (T/T). Across the examined dromedary breeds, both alleles were present, which is probably due to the breeders’ preference for an intermediate hair length. When compared with other camelids, the identified variant was found exclusively in dromedaries with the ancestral allele at c.779 being ‘C’. This study constitutes the first thorough exploration of the FGF5 gene in dromedaries.

ABSTRACTPurposeTo assess the incidence of Stargardt disease (STGD1) and to evaluate demographics of incident cases.MethodsFor this retrospective cohort study, demographic, clinical and genetic data of patients with a clinical diagnosis of STGD1 were registered between September 2010 and January 2020 in a nationwide disease registry. Annual incidence (2014‐2018) and point prevalence (2018) were assessed on the basis of this registry.ResultsA total of 800 patients were registered, 56% were female and 83% were of European ancestry. The incidence was 1.67‐1.95:1,000,000 per year and the point prevalence in 2018 was approximately 1:22,000‐1:19,000 (with and without 10% of potentially unregistered cases). Age at onset was associated with sex (p = 0.027, Fisher’s exact); 1.9x more women than men were observed (140 versus 74) amongst patients with an age at onset between 10 and 19 years, while the sex ratio in other age‐at‐onset categories approximated one. Late‐onset STGD1 (≥45 years) constituted 33% of the diagnoses in 2014‐2018 compared to 19% in 2004‐2008. Diagnostic delay (≥2 years between the first documentation of macular abnormalities and diagnosis) was associated with older age of onset (p = 0.001, Mann–Whitney). Misdiagnosis for age‐related macular degeneration (22%) and incidental STGD1 findings (14%) was common in patients with late‐onset STGD1.ConclusionThe observed prevalence of STGD1 in real‐world data was lower than expected on the basis of population ABCA4 allele frequencies. Late‐onset STGD1 was more frequently diagnosed in recent years, likely due to higher awareness of its phenotype. In this pretherapeutic era, mis‐ and underdiagnosis of especially late‐onset STGD1 and the role of sex in STGD1 should receive special attention.

Published: August 2021

AbstractObservational data collected prior to the pandemic (between 2004 and 2019) were used to simulate the potential consequences of early childhood care and education (ECCE) service closures on the estimated 167 million preprimary‐age children in 196 countries who lost ECCE access between March 2020 and February 2021. COVID‐19‐related ECCE disruptions were estimated to result in 19.01 billion person‐days of ECCE instruction lost, 10.75 million additional children falling “off track” in their early development, 14.18 million grades of learning lost by adolescence, and a present discounted value of USD 308.02 billion of earnings lost in adulthood. Further burdens associated with ongoing closures were also forecasted. Projected developmental and learning losses were concentrated in low‐ and lower middle‐income countries, likely exacerbating long‐standing global inequities.
