Study on the prediction of high-speed rotary lip seal wear in aero-engine based on heat-fluid-solid coupling
Authors: Wei Jian , Xue YuXi , Tian Jing , Guo Fei 
Published: January 2024

Purpose
This paper aims to investigate the effect of frictional heat on the wear of high-speed rotary lip seals in engines.

Design/methodology/approach
In this research paper, the authors focus on the high-speed rotating lip seal of aircraft engines. Using the hybrid lubrication theory, a thermal-fluid-solid coupled numerical simulation model is established to investigate the influence of parameters such as contact pressure distribution, temperature rise and leakage rate on the sealing performance under different operating conditions. By incorporating the Rhee wear theory and combining simulation results with experimental data, a method for predicting the wear of the rotating seal lip profile is proposed. Experimental validation is conducted using a high-speed rotating test rig.

Findings
The results indicate that as the speed increases, the rise in frictional heat leads to a decrease in the sealing performance of the lip seal contact region. The experimental results show a similar trend to the numerical simulation results, and considering the effect of frictional heat, the predicted wear of the lip seal profile aligns more closely with the actual wear curve. This highlights the importance of considering the influence of frictional heat in the analysis of rotating seal mechanisms.

Originality/value
This study provides a reference for the prediction of wear profiles of engine high-speed rotary lip seals.
Contextualizing the “Spanish dream”: using critical HRM to understand immigrant homeownership in Spain, 2000–2009
Authors: Gonzalez-Fuentes Mario , Gilbert Jonathan Ross , Scherer Robert F. , Iglesias-Fernandez Carlos 
Published: January 2024

Purpose
A pronounced rise in postpandemic immigration is creating consumption opportunities and challenges for countries worldwide. Past research has shown that immigrant homeownership indicates advanced consumer acculturation. However, critical factors which differentiate immigrant decisions to purchase a home remain underexplored. This study aims to examine the importance of different identity resources in determining homeownership gaps between immigrant groups in Spain during a dynamic decade.

Design/methodology/approach
A mixed methods research design with triangulation was used. First, the critical “historical research method” is used to empirically assess 15,465 household-level microdata files from the National Immigrant Survey of Spain. Second, the analysis is corroborated through informant interviews, an evaluation of digital news archives and other historical traces such as relevant advertisements in Spain from 2000 to 2009.

Findings
Results provided an account of immigrant homeownership whereby foreign-born consumers leveraged resources to promote social identities aligned with an advanced level of acculturation through housing investment during this period. Furthermore, marketing focused on specific targets of ethnic minority consumers coupled with government policies to promote immigrant homeownership reinforced the “Spanish Dream” as a new paradigm for housing market integration.

Originality/value
Spain provides an unprecedented historical context to explain marketing-related phenomena due to a perfect storm of immigration, job availability and integration supports. Contrary to popular wisdom, immigrant consumer homeownership gaps are not solely a result of differences in income and economic mobility, but rather an advanced acculturation outcome driven by personal and social investments in resources that lead to consumer identities.
The effect of referral tasks on customers’ referral likelihood on social platforms
Authors: Ma Sai , Xie Qinghong , Wang Jiaxin , Dong Jingjing 
Published: January 2024

Purpose
Customer referral programs (CRPs) are popular; however, they often generate low referral rates. The authors propose that certain CRP referral tasks may hinder consumers’ referral likelihood. This study aims to explore the effects of referral tasks (communication content and approach) on customers’ referral likelihood on social platforms and the role of self-construal.

Design/methodology/approach
This study establishes a theoretical model based on online social platforms and conducts three scenario-based experiments. The authors obtain data from consumers on Sojump platform and test the hypotheses using analysis of variance (ANOVA) analysis and mediation analysis in SPSS. The valid sample sizes for these three experiments are 288, 203 and 214, respectively.

Findings
Three experimental studies indicate that communication content and approach have a significant effect on referral likelihood. Furthermore, the effect of communication content on referral likelihood depends on the communication approach. Self-construal plays a moderating role in the effect of communication content and approach on perceived social costs.

Originality/value
CRPs typically involve tasks and rewards; consumers are asked to complete a referral task and then receive a reward. Both tasks and rewards can affect an individual’s willingness to participate; however, existing studies on CRP focus primarily on the reward component. To the best of the authors’ knowledge, this is the first study to systematically investigate the role of referral tasks (communication content and approach) in CRPs. The authors extend the related research by examining the impact of referral tasks on consumers’ willingness to recommend. In addition, this study introduces self-construal into CRPs research.
Investigating the barriers facing corporate social responsibility in the built environment: Ghana’s perspective from a qualitative approach

Published: January 2024

Purpose Several organisations dedicate a portion of their budget and business websites to corporate social responsibility (CSR) events. This illustrates the significance attached to CSR events. In Ghana, a social disconnection may exist between the community and the construction sector. Therefore, this research aims to investigate the benefits of CSR in the construction industry, the implementation challenges and measures to enhance CSR in the Ghanaian built environment.Design/methodology/approach The qualitative technique was adopted using an extensive review of literature supported by structured interviews and analysed by context analysis. The participants include ministry and municipal directors, contractor associations, unions and institutions of engineers. The study achieved saturation.Findings Findings reveal that the construction industry’s CSR impacts the community’s social behaviour and has economic and environmental significance. The absence of government implementation policy and finance constraints were identified as Ghana’s major CSR implementation challenges. Also, besides the government instituting a mandatory policy on CSR in the industry, findings suggest that stakeholders, especially players in the industry and policymakers, should form an integral part of the CSR decisions.Practical implications Findings will support and recommend holistic measures to mitigate CSR implementation hindrances and encourage CSR via a central government's mandatory policy in the Ghanaian built environment.Originality/value Besides most studies used questionnaires, the contribution deduced shows that construction companies' management could use the knowledge from this study and involve all the relevant stakeholders when undertaking CSR activities. Also, the study would fill the scarcity of relevant materials concerning CSR in Ghanaian construction sector.
Organizational politics and employee job performance in the tourism and hospitality industry: workplace stress and counterproductive work behavior
Authors: Al-Romeedy Bassam Samir , Khairy Hazem Ahmed 
Published: January 2024

Purpose
This study aims to explore how job performance (EJP) is affected by employees’ perception of organizational politics (POP). It also investigates the mediating roles of workplace stress (WS) and counterproductive work behavior (CWB).

Design/methodology/approach
Data was gathered from employees working in category (A) travel agencies and five-star hotels in Egypt. A partial least squares structural equation modeling analysis was conducted using 468 valid responses.

Findings
The findings indicate that there is a negative correlation between POP and EJP. Additionally, there is a positive correlation between POP and CWB as well as WS. The results also demonstrate a negative correlation between WS and CWB with EJP. Moreover, the findings suggest that CWB and WS act as partial mediators in the relationship between POP and EJP.

Originality/value
The research included some ground-breaking investigations. Currently, research on the effects of POP on CWB, WS and EJP is insufficient. As well, the current study attempts to measure the mediating role of CWB and WS in the link between POP and EJP. The current study has filled a gap in the tourism and hospitality literature, human resources management literature and organizational behavior literature by empirically analyzing these links in the context of Egyptian hotels and travel agencies.

Abstract

Understanding how different organisms cope with changing temperatures is vital for predicting future species' distributions and highlighting those at risk from climate change. As ectotherms, butterflies are sensitive to temperature changes, but the factors affecting butterfly thermoregulation are not fully understood.

We investigated which factors influence thermoregulatory ability in a subset of the Mediterranean butterfly community. We measured adult thoracic temperature and environmental temperature (787 butterflies; 23 species) and compared buffering ability (defined as the ability to maintain a consistent body temperature across a range of air temperatures) and buffering mechanisms to previously published results from Great Britain. Finally, we tested whether thermoregulatory ability could explain species' demographic trends in Catalonia.

The sampled sites in each region differ climatically, with higher temperatures and solar radiation but lower wind speeds in the Catalan sites. Both butterfly communities show nonlinear responses to temperature, suggesting a change in behaviour from heat‐seeking to heat avoidance at approximately 22°C. However, the communities differ in the use of buffering mechanisms, with British populations depending more on microclimates for thermoregulation compared to Catalan populations.

Contrary to the results from British populations, we did not find a relationship between region‐wide demographic trends and butterfly thermoregulation, which may be due to the interplay between thermoregulation and the habitat changes occurring in each region. Thus, although Catalan butterfly populations seem to be able to thermoregulate successfully at present, evidence of heat avoidance suggests this situation may change in the future.
How does a ‘Jewellery Club’ adaptation of the Lego Therapy intervention impact on social anxiety and interactions between girls aged 7 with social communication interaction difficulties?
Authors: Day Emily , Middleton Tristan 
Published: January 2024

AbstractThis study investigated the impact of a ‘Jewellery Club’ on girls with social, communication and interaction difficulties. The project focussed on three girls aged seven who participated in an intervention using similar principles to the ‘Lego Therapy’ intervention. An action research approach was followed, where two phases of the intervention were undertaken with participants engaging with a weekly 20 min session for 3 weeks per phase. The impact of the intervention was assessed through the use of a social difficulties log, field notes and unstructured interviews with parents. Findings identified an overall reduction in social difficulties and social anxiety related to school as well as improved play experiences for the participants during unstructured school times and highlighted the importance of the intervention being aligned with the interests of the participants. The findings suggest that reflection on the gendered nature of interventions may be useful when considering how research might be implemented in practice.

Published: January 2024

AbstractObjectiveTo model the potential impact of mobile methadone unit implementation in Louisiana on net medication for opioid use disorder (MOUD) treatment rates.Data Sources/Study SettingWe use secondary Louisiana Medicaid claims data between 2020 and 2021.Study DesignWe simulate the impact of mobile methadone units in Louisiana using two approaches: (1) a “Poisson regression approach,” which predicts the number of opioid use disorder (OUD) patients that might use methadone at mobile locations based on the underlying association between methadone use and proximity to a brick‐and‐mortar methadone clinic; (2) a “policy approach,” which leverages local treatment uptake rates following the expansion of methadone coverage to Louisiana Medicaid beneficiaries in 2020 to estimate methadone use following mobile unit implementation. Models were run in cases where mobile methadone operators could choose their operation locations freely and in a separate instance where they were restricted to serving rural locations.Data CollectionOur analytic sample includes 43,341 Louisiana Medicaid beneficiaries with one or more primary or secondary diagnoses for opioid dependence.Principal FindingsWe predict that 10 new mobile methadone units in Louisiana would increase the net MOUD treatment rate in the state by 0.54–2.39 percentage points. If these mobile units delivered Methadone exclusively to rural areas, they could increase rural MOUD treatment by 8.54–13.67 percentage points. Further, roughly 20% of all beneficiaries residing in rural areas being treated with methadone would be an average of 24 miles closer to a methadone treatment provider following mobile unit implementation.ConclusionsMobile methadone units represent a promising innovation in the delivery of methadone that is likely to increase methadone use, especially in underserved rural locations. However, we find significant variation in their impact conditional on where they choose to operate, and so careful location planning will be required to maximize their benefit.
Characterization of fruit pulp‐soy protein isolate (SPI) complexes: Effect of superfine grinding
Authors: Xie Jin , Lyu Jian , Wang Fengzhao , Bai Lansha , Bi Jinfeng 
Published: January 2024

AbstractSuperfine grinding (SG), as an innovative technology, was conducted to improve the physicochemical and structural properties of fruit pulps. Nectarine, apple, and honey peach were selected as the materials. With the increase in SG frequency, the soluble solids content, viscosity, D[4, 3], D[3, 2], G′ and G″ of fruit pulps were evidently decreased, whereas the turbidity was increased. The smallest D[4, 3] (294.90 µm) and D[3, 2] (159.67 µm) were observed in nectarine pulp under SG at 50 Hz. The highest turbidity (266.33) was shown in honey peach pulp under SG at 50 Hz. The active groups of the fruit pulps with SG were exposed by Fourier transform infrared spectroscopy (FT‐IR). Notably, the excessive destruction in structure was confirmed in SG with 50 Hz. With soy protein isolate (SPI) addition, D[4, 3] and D[3, 2] of complexes decreased, whereas G′ and G″ increased. The formation of new fruit pulp‐SPI complexes was demonstrated by FT‐IR and LF‐NMR analysis. The dense and uniform structure was found in complexes prepared by SPI and fruit pulp with 30 Hz SG. Especially, apple‐SPI complex with 30 Hz SG showed the highest water‐holding capacity (WHC) (0.75) and adhesiveness (7973.00 g s). A significant correlation between fruit pulps and the complexes was revealed. Taken together, the impact of SG modification on fruit pulps would enhance WHC, rheology, and textural properties of the fruit pulp‐SPI complexes, especially for SG with 30 Hz.Practical ApplicationThis research provided a comprehensive exploration of the potential of SG technology to modify fruit pulps, solving the diversity of textural customization problems and offering valuable insights for the development of semisolid food products.
Differential expression of ASIP transcripts reveals genetic mechanism underpinning black‐tail independence from body plumage in yellow‐bodied chickens

Published: January 2024

AbstractThe genetic foundation of chicken body plumage color has been extensively studied. However, little attention has been paid to the inheritance patterns and molecular mechanisms underlying the formation of distal feather colors (tail and wingtip). Differences in these colors are common; for example, the Chinese Huiyang Beard chicken has black tail feathers, but yellow body plumage. Here, the hybrid offspring of Huiyang Beard and White Leghorn chickens were used to study the inheritance patterns of tail‐feather color. The expression levels of pigment genes in differently colored feather follicles were analyzed using quantitative real‐time PCR. The results showed that genetic regulation of tail‐feather color was independent of body‐plumage color. The Dominant White locus inhibited eumelanin synthesis in tail feathers without affecting the formation of yellow body plumage, whereas the Silver locus had the opposite effect. The expression of agouti signaling protein (ASIP) gene class 1 transcripts was significantly lower in black tail‐feather follicles than in yellow body follicles, whereas tyrosinase‐related protein 1 (TYRP1) gene expression was significantly higher in black tail feathers. These differentially expressed genes were confirmed to exert an effect on eumelanin and pheomelanin formation in feathers, thus influencing the regulation of chicken tail‐feather color. In conclusion, this study lays the foundation for further research on the genetic mechanisms of regional differences in feather color, contributing to a better understanding of plumage pigmentation in chickens.
Tick bites, IgE to galactose‐alpha‐1,3‐galactose and urticarial or anaphylactic reactions to mammalian meat: The alpha‐gal syndrome
Authors: Wilson Jeffrey M. , Erickson Loren , Levin Michael , Ailsworth Samuel M. , Commins Scott P. , Platts‐Mills Thomas A. E. 
Published: January 2024

AbstractThe recent recognition of a syndrome of tick‐acquired mammalian meat allergy has transformed the previously held view that mammalian meat is an uncommon allergen. The syndrome, mediated by IgE antibodies against the oligosaccharide galactose‐alpha‐1,3‐galactose (alpha‐gal), can also involve reactions to visceral organs, dairy, gelatin and other products, including medications sourced from non‐primate mammals. Thus, fittingly, this allergic disorder is now called the alpha‐gal syndrome (AGS). The syndrome is strikingly regional, reflecting the important role of tick bites in sensitization, and is more common in demographic groups at risk of tick exposure. Reactions in AGS are delayed, often by 2–6 h after ingestion of mammalian meat. In addition to classic allergic symptomatology such as urticaria and anaphylaxis, AGS is increasingly recognized as a cause of isolated gastrointestinal morbidity and alpha‐gal sensitization has also been linked with cardiovascular disease. The unusual link with tick bites may be explained by the fact that allergic cells and mediators are mobilized to the site of tick bites and play a role in resistance against ticks and tick‐borne infections. IgE directed to alpha‐gal is likely an incidental consequence of what is otherwise an adaptive immune strategy for host defense against endo‐ and ectoparasites, including ticks.

Authors: Al‐Ameri Abdulahad Abdulrab Moahmmed , Zheng Shusen 
Published: January 2024

AbstractBackgroundCaudate lobectomy (CLB) remains the most effective treatment for caudate lobe hepatocellular carcinoma (CL‐HCC). However, there is controversy regarding the survival after CLB. This meta‐analysis aims to investigate the survival outcomes following CLB for the treatment of CL‐HCC.MethodsIn line with PRISMA and MOOSE guidelines, a search for all eligible studies was performed. The pooled estimates of survival rates and hazard ratios (HRs) with their 95% confidence intervals (CIs) were calculated using fixed‐ or random‐effects models.ResultsSixteen studies comprising 864 patients met the inclusion criteria. The pooled estimates of 3‐ and 5‐year overall survival (OS) rates were 62.3% and 42.9% respectively and the pooled estimate of 3‐ and 5‐year recurrence‐free survival (RFS) rates were 39.3% and 24.4% respectively. CL‐HCC showed inferior OS (HR:1.39, 95% CI: 0.91–1.88, P < 0.001) and RFS (HR:1.33, 95% CI: 1.10–1.56, P < 0.001) than other sites HCC. Isolated CLB showed better OS (HR:0.9, 95% CI:0.39–1.41, p < 0.001) and RFS (HR:0.76, 95% CI: 0.03–1.5, P = 0.04) than combined CLB.ConclusionsThe survival outcomes for CL‐HCC after CLB are lower compared to other sites HCC. Isolated CLB offers better survival outcomes compared to combined CLB. However, choosing isolated or combined approaches should be prioritized according to patient and tumour characteristics.

AbstractRefugees experience elevated rates of mental health problems, but little is known about mental health service utilization and quality among asylum seekers and refugees in Europe. In a 12‐month follow‐up study of newly arrived refugees (N = 166, Mage = 32.38 years, 30.7% female) and a nationwide cross‐sectional study (N = 579, Mage = 33.89 years, 36.2% female) of refugees who had been living in Germany for an average of 6 years, we examined objective need for mental health treatment, perceived need, access to treatment services, and adequacy of treatment. We defined minimally adequate mental health treatment according to the WHO World Mental Health Survey as ≥8 sessions of psychotherapy (minimally adequate psychotherapy) or pharmacotherapy plus ≥4 medical visits (minimally adequate pharmacotherapy). In both studies, two in three individuals screened for mental health symptoms and additionally perceived a need for professional treatment. Of those, less than half had contact to any service provider, with only 1 in 14 receiving minimally adequate psychotherapy. Overall, no more than one in seven of refugees in need received minimally adequate treatment. Despite a comprehensive mental health‐care system, refugees' access to mental health care and the treatment provided are inadequate. Health policies are urgently needed to provide equitable mental health care for all.
