Flow and heat transfer analysis of laminar flow in hypersonic aircraft with variable specific heat capacity at small attack angles
Authors: Du Mengxia , Wang Qiao , Zhang Yan , Bai Yu , Wei Chunqiu , Liu Chunyan 
Published: November 2023

Purpose
As to different angles of attack and nonlinear problems caused by high temperatures in coexisting hypersonic aircraft, people mainly rely on fluid software for research but lack analysis of flow mechanisms. Owing to computational difficulties, few people use numerical algorithms to combine them for discussion. Hence, this study aims to make a deep inquiry into the laminar flow and heat transfer of compressible Newtonian fluid in hypersonic aircraft with small attack angles.

Design/methodology/approach
In this paper, on the basis of mass, momentum and energy conservation laws, the governing equations of the hypersonic boundary layer are established. Viscosity, specific heat capacity and thermal conductivity are considered nonlinear functions concerning temperature. In virtue of the MacCormack finite difference method, the stationary numerical solutions are solved directly, and the validity of the algorithm is verified.

Findings
The results demonstrate that at Mach number 5, compared to the 0° attack angle, the maximum temperature near-wall at the 3° attack angle increases by about 25%. An enjoyable phenomenon is discovered, where the position corresponding to the maximum wall shear force shifts back as the attack angle and Mach number increase. The relationship between the near-wall maximum temperature versus attack angle and Mach number is fitted through numerical calculation results.

Originality/value
Empirical formulas can be used to estimate heat transfer characteristics at small attack angles, which will guide the design of aircraft thermal protection systems.

Authors: Kim Kyoung Tae , Xiao Jing Jian , Porto Nilton 
Published: November 2023

PurposeFinancial inclusion can be proxied by banking status. The purpose of this study is to investigate the potential effects of financial capability on the financial fragility of US adults with various banking statuses during the COVID-19 pandemic.Design/methodology/approachThis study utilized the 2021 National Financial Capability Study (NFCS) dataset to investigate the relationship between financial capability and financial fragility among consumers with different banking statuses. The analysis controlled for employment shocks, health shocks and other consumer characteristics. Banking statuses included fully banked, under-banked (utilizing both banking and alternative financial services) and unbanked individuals. Logistic regression analyses were conducted on both the entire sample and subsamples based on banking statuses.FindingsThe results showed that financial capability was negatively associated with financial fragility. The magnitude of the potential negative effect of financial capability was the greatest among the fully banked group, followed by the underbanked and unbanked groups. Respondents who were underbanked or unbanked were more likely to experience financial fragility than those who were fully banked. Additionally, respondents who were laid off or furloughed during the pandemic were more likely to experience financial fragility than those without employment shocks. The effect size of financial capability factors was greater than that of COVID-19 shock factors. These results suggest that higher levels of both financial capability and financial inclusion may be effective in reducing the risk of financial fragility.Originality/valueThis study represents one of the first attempts to examine the potential effects of financial capability on financial fragility among consumers with various banking statuses during the COVID-19 pandemic. Furthermore, this study offers new evidence to determine whether COVID-19 shocks, as measured by health and employment status, are associated with financial fragility. Additionally, the effect size of financial capability factors is greater than that of COVID-19 shock factors. The results from the 2021 NFCS dataset provide valuable insights for banking professionals and public policymakers on how to enhance consumer financial wellbeing.
The infiltration of LGBTQ+ safe spaces
Authors: Baxter Daniel , Jones Steve , Leer Claire 
Published: November 2023

PurposeLGBTQ+ spaces are often considered as safe havens for the LGBTQ+ community, as they can gather free from prejudice and fear. This research explores the effect that heterosexual people attending LGBTQ+ venues have on this community. This paper considers the impacts on the community, the importance of their safe spaces and identifies practical implications to be considered in protecting these spaces.Design/methodology/approachThe study implemented a multi-method qualitative data collection approach with LGBTQ+ community venue attendees in the UK. Stage 1 utilised an online qualitative survey and collected data from 558 respondents. Stage 2 saw critical incident techniques (CITs) used with 12 participants. The data collected were analysed using a thematic system.FindingsThe LGBTQ+ community has experienced an increase in frustration and fear as a result of more heterosexual attendees infiltrating their safe spaces. Both participants and respondents discussed the importance that security personnel play in ensuring safe spaces. Finally, the findings demystified that not all attendees in LGBTQ+ venues are allies, and that there is a need for those outside the community to better understand the importance of these spaces for the LGBTQ+ community, as many heterosexuals do not consider how they should act.Research limitations/implicationsLimitations associated with the implementation of the CIT were identified. Further training is advised for researchers employing this method to prepare them for dealing with the emotional impact of participants’ experiences.Practical implicationsThis study highlighted the need for security and staff working at LGBTQ+ venues to undergo extensive inclusivity training, and for stricter door policies. Participants also argued for LGBTQ+ venues to educate heterosexual attendees about the community and their historical and present-day struggles and culture.Originality/valueThis paper is of practical value to those who organise and manage LGBTQ+ events, bars and nightclubs. An enhancement to the four types of space framework originated by Castilhos and Dolbec (2018) has been identified.
Optimal and economic design of modified double sampling plan under new Weibull–Pareto distribution
Authors: Sankara Narayanan M. , Jeyadurga P. , Balamurali S. 
Published: November 2023

PurposeThe purpose of this paper is to design a modified version of the double sampling plan to handle the inspection processes requiring a minimum sample size to assure the median life for the products under the new Weibull–Pareto distribution. The economic design of the proposed plan is also considered to assure the product's lifetime with minimum cost.Design/methodology/approachThe authors have developed an optimization model for obtaining the required plan parameters by solving simultaneously two non-linear inequalities and such inequalities have been formed based on the two points on the operating characteristic curve approach.FindingsThe results show that the average sample number, average total inspection and total inspection cost under the proposed plan are smaller than the same of a single sampling plan. This means that the proposed plan will be more efficient than a single sampling plan in reducing inspection effort and cost while providing the desired protection.Originality/valueThe proposed modified double sampling plan designed to assure the median life of the products under the new Weibull–Pareto distribution is not available in the literature. The proposed plan will be very useful in assuring the product median lifetime with minimum sample size as well as minimum cost in all the manufacturing industries.

Published: November 2023

Purpose
This study aims to investigate tourists’ impressions of the smart destinations model from the socio-technical systems and the technology–organization–environment (TOE) perspectives. Specifically, it aims to explore how information source credibility and cloud infrastructure influence tourists’ use of intelligent technology.

Design/methodology/approach
This measurement development is based on prior literature; after being evaluated for face and content validity, the authors used random sampling to collect data and conducted a field survey of tourists through Taoyuan Airport and using the airport MRT between December 2022 and March 2023. After confirming that tourists knew the destination information and had experience using travel-related mobile applications to plan their itinerary, the authors further invited tourists to participate in the survey, and 512 valid questionnaires were analyzed by the structural equation modeling approach.

Findings
The finding pointed out that source credibility and intelligent technology were innovative technologies that benefitted tourists, as were mobile travel planning apps, which created a relational context based on interests and activities from the socio-technical and TOE perspectives.

Originality/value
Technological innovation is closely related to the development of smart cities; tourists who used travel itineraries successfully understood travel-related actions and significantly had more positive affective images of the city.

Dynamic behavior of hydrostatic squeeze film dampers fed through four capillary restrictors with micropolar lubricant
Authors: Benariba Aboubakeur , Bouzidane Ahmed , Aboshighiba Hicham , Thomas Mark 
Published: November 2023

Purpose
The purpose of this research is to study the dynamic behavior of hydrostatic squeeze film dampers made of four hydrostatic pads, fed through four capillary restrictors with micropolar lubricant.

Design/methodology/approach
The modified version of Reynolds equation is solved numerically by the finite differences and the Gauss–Seidel methods to determine the pressure field generated on the hydrostatic bearing flat pads. In the first step, the effects of the pad dimension ratios on the stiffness and damping coefficients are investigated. In the second step, the damping factor is evaluated with respect to the micropolar properties.

Findings
The analysis revealed that the hydrostatic squeeze film dampers lubricated with micropolar lubricants produces the maximum damping factor for characteristic length of micropolar lubricant less than 5, while the same bearing operating with Newtonian lubricants reaches its maximum damping factor at eccentricity ratios larger than 0.4.

Originality/value
The results obtained show that the effects of micropolar lubricants on the dynamic performances are predominantly affected by the pad geometry and eccentricity ratio.

Authors: Lochman Josef , Vágner Jiří 
Published: November 2023

PurposeMeat overconsumption by tourists is one of the key issues in the sustainability of tourist destinations. The objective of this paper is to assess the impact that a promotion of meatless gastronomy and its actual increased availability would have on the attractiveness and visitation of a popular European urban destination.Design/methodology/approachThe research uses an innovative foresight approach that combines environmental scanning and scenarios. The authors formulated the scenarios using the Delphi technique and working with 27 scholars whose insights into the topic were enhanced through theses that resulted from the environmental scanning. They provided their insights into how a promotion of meatless gastronomy would affect a destination. Subsequently, the authors synthetized their insights and formulated the scenarios.FindingsBased on two defined scenarios, the authors found that a meatless image represents an opportunity for the future development of an urban European destination. A long-term growth in visitor numbers can be achieved while ensuring environmental, economic and socio-cultural sustainability providing that relevant stakeholders are involved in the promotional activities.Originality/valueManagement of tourists' unsustainable eating habits is currently an unexplored issue. The present research addresses this topic and provides valuable insights that will help to address sustainability issues while making tourism destinations more attractive.
Board's informal hierarchy: influences on enterprise innovation quality
Authors: Meng Delin , Li Yanxi , Wang Lan 
Published: November 2023

PurposeUtilizing the expectation states theory in sociology, this study probes into the influence of the board's informal hierarchy on the quality of enterprise innovation, originating from the perspective of internal directorial interactions, while analyzing the boundary effects exhibited by the nature of property rights and the intensity of geo-culture.Design/methodology/approachThe study selects China's A-share listed companies from 2008 to 2021 as the research sample, employing the Tobit regression analysis method to scrutinize the hypotheses presented in the text.FindingsThe regression results demonstrate a positive correlation between the board's informal hierarchy and the enterprise innovation quality (EIQ). Upon introducing variables specific to property rights and geographical culture, the authors found that in comparison to non-state-owned enterprises (non-SOEs), the influence of the board's informal hierarchy on the quality of corporate innovation is diminished in SOEs. Conversely, the intensity of geo-culture across Chinese provinces enhances their mutual positive influence. In the additional analysis, the authors also found that the elevation of corporate risk tolerance is a significant pathway for the positive effect of the board's informal hierarchy on EIQ. Moreover, this positive influence is more profound in high-tech enterprises, businesses implementing equity incentive plans and companies that have subscribed to director and officer liability insurance.Originality/valueThe findings not only deepen the understanding of how the board's internal status characteristics influence corporate decision-making but also enrich the application scope of expectation states theory. Furthermore, this study offers valuable guidance for optimizing innovation decision-making by adjusting the personnel structures of corporate boards.
Participatory knowledge co-production to activate culture in the development of small cities and rural areas in Portugal
Authors: Duxbury Nancy , Bakas Fiona Eva , Carvalho Cláudia Pato 
Published: November 2023

Purpose
Culture is increasingly recognized as a key component of local development, but this attention is largely focused on large cities. This paper aims to focus on the ways in which the innovative, participatory action-research (PAR) methods of IdeaLabs and community intervention workshops are used by two projects with solidarity economy enterprise (SEE) participants to activate place-based cultural resources for local development in small communities.

Design/methodology/approach
An in-depth reflexive analysis undertaken by researchers involved in the two projects, taking a feminist ethics of care perspective, demonstrates the ways in which these two PAR methods promote local development with the goal of fighting against the economic, social and cultural degradation of small cities and rural areas.

Findings
The PAR methods used by the two projects examined stimulate place-based local development initiatives through collaboration and knowledge co-production among participants and researchers. The projects go beyond an instrumental view of the use of culture and the arts for local development to innovate and demonstrate new methodologies for more participatory approaches.

Originality/value
This paper addresses a gap in social economy literature, presenting methods that can be used in PAR projects to catalyse the use of culture as a local development tool by local SEEs.
Strong phylogenetic signal and models of trait evolution evidence phylogenetic niche conservatism for seagrasses
Authors: Tuya Fernando , Martínez‐Pérez Javier , Fueyo Álvaro , Bosch Néstor E. 
Published: November 2023

Abstract

Phylogenetic signal (PS) is the propensity of closely related species to resemble each other. PS has been tested across clades of terrestrial plants; however, insight for seagrasses is still lacking. Signatures of PS and models of niche (trait) evolution can help to detect phylogenetic niche conservatism (PNC), that is, close relatives live in comparable niches.

The initial goal of this study was to assess the pattern of PS for the world's seagrasses, by testing the non‐independence of phylogenetic relatedness and seagrass species traits. A phylogeny of 49 seagrasses was constructed, together with a matrix of nine traits covering morphological, life‐history and reproductive attributes. PS of traits was tested through complementary indices (Pagel's λ, Blomberg's K, Moran's I and Abouheif's Cmean). Three models of niche evolution (Brownian Motion, BM; Ornstein–Uhlenbeck, OU; Early Burst, EB) were then fitted to each trait and the multivariate trait matrix.

Results supported the existence of strong PS for seagrasses, with a particularly large effect size for seagrass reproductive traits, which followed an EB evolution model. Local Indicators of Phylogenetic Association (local autocorrelation metrics that can help to identify areas of large autocorrelation) supported the presence of PS across seagrass lineages/clades, supported by the dominance of OU as the most parsimonious trait evolution model.

The pattern of strong PS seems to be a consequence of long‐term PNC of seagrass traits after initial radiation.

Synthesis: Our study highlights the relevance of evolution from common ancestors and shared history underpinning large seagrass phylogenetic structuring.
Single mother parenting of children with autism spectrum disorder: A qualitative photo‐narrative study
Authors: Lavian Rivka Hillel , Kimhi Yael , Shmuelovich Tamar 
Published: November 2023

AbstractOver the past few decades, there has been a shift from the traditional family structure, with more acceptance of different structures, including those led by single parents. This qualitative photo‐narrative study aimed at making the voices of single mothers raising children with autism spectrum disorder (ASD) heard. According to the literature, parenting a child with a disability can be very stressful on several different levels. Seven single mothers living in southern Israel and parenting children with ASD told their life stories and took photographs depicting their motherhood experience. The data underwent thematic content analysis. The main themes that emerged were the shattering of the family dream, the mothers and the educational setting, the present in the shadow of the future, single parents' support resources and the mothers' search for meaning. The data demonstrated that the mothers' daily life was rife with challenges. Providing assistance and support during different stages, including diagnosis, educational transitions and daily struggles, as outlined in the Dual Process Model of Coping with Bereavement, was crucial. The mothers also stressed that they drew strength from their love for their child and their existing support systems.
Dynamics in the Bioeconomy: Markets for Amino Acids and Insect Biomass
Authors: Sturm Viktoriya 
Published: November 2023

SummaryWhile the bioeconomy permeates all sectors, respective markets are subject to different dynamics. Markets for bio‐based amino acids and insect biomass illustrate this. The global and EU markets for bio‐based amino acids are well‐established and growing. However, the increase in production in the EU of some ‘new’ amino acids is much smaller than the decrease in production of well‐established lysine and threonine that has resulted from the relocation of the production of these amino acids from the EU to Asia (an effect of higher production costs and stricter environmental standards in the EU). The result is that overall production of amino acids has decreased significantly.The market for insect biomass is just emerging in the EU. Production is low, but companies are starting to upscale. The animal feed market is a major target market for free amino acids and insect biomass. Free amino acids are classified as feed additives and placing them on the feed market is costly. Insect meal is a feed material and placing it on the market is quite straightforward, although its use in feed for poultry and pigs was approved only in September 2021. Free amino acids are common ingredients of animal feed, but their use is prohibited in organic farming. The use of insect meal in organic farming is not prohibited, but a corresponding certification is not yet developed in the EU.
