An effort saving method to establish global aerodynamic model using CFD
Authors: Xie Jingfeng , Huang Jun , Song Lei , Fu Jingcheng , Lu Xiaoqiang 
Published: May 2022

Purpose
The typical approach of modeling the aerodynamics of an aircraft is to develop a complete database through testing or computational fluid dynamics (CFD). The database will be huge if it has a reasonable resolution and requires an unacceptable CFD effort during the conceptional design. Therefore, this paper aims to reduce the computing effort required via establishing a general aerodynamic model that needs minor parameters.

Design/methodology/approach
The model structure was a preconfigured polynomial model, and the parameters were estimated with a recursive method to further reduce the calculation effort. To uniformly disperse the sample points through each step, a unique recursive sampling method based on a Voronoi diagram was presented. In addition, a multivariate orthogonal function approach was used.

Findings
A case study of a flying wing aircraft demonstrated that generating a model with acceptable precision (0.01 absolute error or 5% relative error) costs only 1/54 of the cost of creating a database. A series of six degrees of freedom flight simulations shows that the model’s prediction was accurate.

Originality/value
This method proposed a new way to simplify the model and recursive sampling. It is a low-cost way of obtaining high-fidelity models during primary design, allowing for more precise flight dynamics analysis.
The viticulture revolution @ Tabor Winery: Michal Akerman’s visionary leadership
Authors: Kumar K.B.S. 
Published: May 2022

Study level/applicability
MBA/MS/Executive Training.

Subject area
Business and society; sustainability; women business leaders.

Case overview
This case is about the development of sustainable viticulture in Israel. Michal Akerman, a viticulturist and agronomist, implemented out-of-the box ideas at Tabor Winery, Israel, and was successful in developing organic and sustainable vineyard. However, she faced challenges in terms of improving the quality of grapes as she looked forward to growing some of the best quality French grapes in Israel in the challenging conditions of the Negev desert region.

Expected learning outcomes
The expected learning outcomes are: to analyze the environmental impact of viticulture and sustainable viticulture through Tabor’s example, to examine how leaders can drive businesses to be involved in sustainable practices and challenges involved in implementing sustainable practices and to develop a framework for female leaders working in male-dominated business environments.

Social implications
This case captures Michal Akerman’s (Michal) endeavours to develop organic and sustainable viticulture at Israel-based Tabor Winery. The traditional practices followed to grow the vineyards were proving adverse to the biodiversity. Unsustainable practices wiped out rare plants, and micro-organisms, which were essential for cultivation of grapes. The imbalance and unnatural ecosystem ultimately posed a threat to the very sustenance of the vineyards. As a seasoned viticulturist, Michal was of the view that a stable, diverse and balanced ecosystem prevented diseases among plants, and improved the quality of grapes.

Published: May 2022

PurposeThis study aims to examine the antecedents of privacy concerns in the era of artificial intelligence. Specifically, it focuses on the impact of various factors related to interactions with a chatbot (creepiness and perceived risk) and individual traits (familiarity with chatbots and need for privacy) in relation to privacy when interacting with a chatbot in the context of financial services. The moderating effect of gender on these relationships was also examined.Design/methodology/approachA total of 430 Canadians responded to an online questionnaire after interacting with a chatbot in the context of a simulated auto insurance quote. A structural equation model was used to test the hypotheses.FindingsThe results showed that privacy concerns are influenced primarily by creepiness, followed by perceived risk and the need for privacy. The last two relationships are moderated by gender. Conversely, familiarity with chatbots does not affect privacy concerns in this context.Originality/valueThis study is the first to consider the influence of creepiness as an antecedent of privacy concerns arising from interactions with AI tools and highlight its key impacts. It also shows how gender moderates specific relationships in this context.
The interplay between relationships, technologies and organizational structures in enhancing supply chain resilience: empirical evidence from a Delphi study
Authors: Küffner Christoph , Kopyto Matthias , Wohlleber Annika Judith , Hartmann Evi 
Published: May 2022

PurposeCOVID-19 has highlighted the need to reflect on how firms should improve their supply chains (SCs) to enhance agility and robustness. Recent studies focus more on the short-term rather than on the long-term developments and lack insights regarding the enhancement of supply chain resilience (SCRES) based on the interplay between multiple levers. Therefore, using a long-term perspective, this research evaluates the interaction between three SCRES levers – relationships, technologies and organizational structures – to improve SCRES.Design/methodology/approachBased on an extensive literature review, multiple interviews and workshops, 13 future projections were developed. These projections were assessed using a two-round Delphi study that included 83 international experts from industry, academia and politics/associations to determine the probability of occurrence by 2035, their impact on SCRES and their desirability.FindingsThis study provides empirical evidence that the long-term enhancement of SCRES is achieved through the interplay of multiple levers rather than unilateral optimization. The study suggests that, by 2035, collaboration between SC partners will be a key factor for SCRES enhancement. Additionally, SC stakeholders should be aware that failing to invest in digital technologies will negatively impact the agility and robustness of future SCs. Furthermore, humans are expected to continue to play a major role, given that relationship-oriented tasks are perceived to remain important.Originality/valueThis paper adds to current literature, describing how SCRES can be improved in the long term through the interplay of multiple levers and the combination of robust and agile elements. Considering the importance of ensuring resilient SCs, this paper provides valuable insights for academics and practitioners.
Emotions, identity, social bonds and commitment to the family business: moderating role of controlling generation
Authors: Razzak Mohammad Rezaur 
Published: May 2022

Purpose
Drawing on the stakeholder theory, the purpose of this study is to examine relationships between family identity, emotional attachment and binding social ties, and commitment of family firm owners to the family enterprise in the context of an emerging economy. Furthermore, this study examines whether the strength of the above relationships significantly vary between the founder generation and the subsequent generation of owners.

Design/methodology/approach
A set of hypotheses is tested by applying partial least squares structural equation modeling on a sample of 357 family-owned manufacturing companies in Bangladesh. Deploying SmartPLS (v. 3.2), the path model is analyzed through bootstrapping procedure. The moderating effect is tested through multigroup analysis.

Findings
The findings suggest that the relationships between emotional attachment and family identity and commitment are positive and significant, whereas the association between binding social ties and commitment was not significant. Furthermore, a multigroup analysis revealed that there is a significant difference between the founder generation and their next generation in terms of influence of binding social ties and family identity on commitment, whereas there appears to be no difference in terms of emotional attachment and commitment between the two generations.

Practical implications
This study shows that compared to the founder generation, the next generation prioritizes family identity and social bonds, which leads to greater levels of collective commitment to the organization. Such knowledge may provide clues to incumbent family-firm leaders by identifying the areas where they need to emphasize in generating greater levels of commitment among their successors.

Originality/value
To the best of the author’s knowledge, this appears to be the first such study that provides a nuanced understanding of how family generation in control of the family firm influences the relationships between psychosocial components of socioemotional wealth and collective commitment of the owners of family firms in the context of an emerging economy.

Authors: Kukah Augustine Senanu Komla , Owusu-Manu De-Graft , Badu Edward , Edwards David John 
Published: May 2022

Purpose
This study aims to evaluate the key risk factors inherent in public–private partnership (PPP) power projects in Ghana and further determine the critical risk factors affecting both the public and private sectors in PPP power projects.

Design/methodology/approach
Ranking-type Delphi survey in two rounds was conducted to establish a comprehensive list of critical risk factors of PPP. Purposive and snowball sampling techniques helped obtain experts for the Delphi survey. Mean score ranking, factor analysis, Cronbach α coefficient and Kendall’s concordance were used for analysis. The probability of occurrence and severity of each risk factor were computed to obtain the risk impact.

Findings
From the list of 67 risks, 37 risk factors were deemed to be critical. The five topmost risk factors were: delay payment on contract, private investor change, political risks, fluctuating demand of power generated and public opposition. Principal component analysis grouped the risk factors into seven major themes.

Originality/value
This study develops an authoritative risk factor list for PPP power projects, which reflects both sector and country conditions for prioritizing and mitigating risk factors. Delphi approach adopted in this study can be used by future studies in similar environments where PPP is novel and expert respondents scarce.

Published: May 2022

Purpose
This study aims to examine the results of structural equation modelling in applying unified theory of acceptance and use of technology in adopting Islamic Fintech among millennials in Malaysia via measurement and structural models.

Design/methodology/approach
A total of 418 valid responses have been obtained from Malaysians who are using Islamic Fintech. Before the data is analysed into measurement and structural modelling preliminary analysis such as common method bias has been conducted.

Findings
All the requirements for model fit in this study have been achieved. Four exogenous constructs are performance expectancy, effort expectancy, social influence and facilitating condition. The mediating construct is behavioural intention, whereas the endogenous variable is user adoption. All exogenous constructs show significant p-values except for effort expectancy.

Practical implications
This study offers important implications, specifically for the digital economy that is currently making its way throughout every aspect of human life, namely, social, religious, financial transaction, entertainment and others. The impact of the digital economy can be traced through the emergence of Fintech. The adoption of Islamic Fintech is one of the least discussed areas academically, therefore, this study is considered necessary to explore the prediction of consumer behaviour in Islamic Fintech adoption as a part of the digital economy in Malaysia.

Originality/value
This study fills the perceived gap in the existing financial technology literature by assessing Islamic financial technology adoption via measurement and structural modelling.

Authors: Ahamad Kuris Nur Hazirah , Mohd Zahir Mohd Zamre , Mohd Ali Hasani , Hassan Muhamad Sayuti 
Published: May 2022

Purpose
Corporate gift-giving and hospitality are some of the high-risk areas for corruption. This paper aims to see comparisons between the Malaysian Ministerial Guidelines and the UK Guidance and to analyse whether the guideline in Malaysia is adequate in dealing with corporate gift-giving and hospitality.

Design/methodology/approach
The methodology used in this paper is qualitative research which is based on data collection through online searches, legal databases, information obtained from articles, books, statutes and related government publications.

Findings
The findings show that the statutory guideline in Malaysia is immature, still not adequate, and lacks detailed regulations in determining gifts and hospitality as corruption (unclear boundary), as compared to the UK law which is more detailed.

Originality/value
This paper explains on comparison of corporate gift giving and hospitality practise in Malaysia and the UK based on the statutory guidelines.
Fine grid model for the dielectric characteristics of ground‐penetrating radar in mixed media

Published: May 2022

ABSTRACTThe Fisher–Yates random shuffling algorithm combined with the finite‐difference time‐domain method is proposed to construct a fine grid model for the forward simulation of ground‐penetrating radar in mixed media. First, the finite‐difference time‐domain method was used to divide the coarse grid model into several fine grid models by conforming to the boundary conditions of different media, and the corresponding dielectric parameters were assigned to Yee cells in each fine grid model. Then, the Fisher–Yates random shuffling algorithm was used to randomly scramble all Yee cells with equal probability, and the array of scrambled Yee cells was recombined into a coarse grid model. Finally, the geoelectric model of mixed media was generated with the finite‐difference time‐domain method, and a ground‐penetrating radar image excited by electromagnetic wave pulses was obtained. To explore the characteristic signals and dielectric properties of the ground‐penetrating radar electromagnetic response in mixed media, image entropy theory was used to describe the ground‐penetrating radar image, and waveform analysis and wavelet transform mode maximum methods were used to analyse the single‐channel ground‐penetrating radar signal of the mixed media. The results showed that the Fisher–Yates random shuffling–finite‐difference time‐domain method can be used to construct a valid and stable fine grid model for simulating ground‐penetrating radar in mixed media. The model effectively inhibits electromagnetic attenuation and energy dissipation, and the wavelet transform mode maximum method explains the relative dielectric permittivity distribution of the mixed media. The findings of this study can be used as a theoretical basis for correcting radar parameters and interpreting images when ground‐penetrating radar is applied to mixed media.
RuBPY decreases intracellular calcium by decreasing influx and increasing storage
Authors: Pereira Amanda de Carvalho , Araújo Alice Valença , Paulo Michele , da Silva Roberto Santana , Bendhack Lusiane Maria 
Published: May 2022

Abstractcis‐[Ru(bpy)2(py)NO2](PF6) (RuBPY) is a ruthenium complex nitric oxide (NO) donor that presents a nitrite in its moiety and has been shown to induce vasodilation in various arteries, as well as arterial pressure reduction with no changes in heart rate. Because vascular tone is highly dependent on the cytosolic calcium concentration ([Ca2+]c), the current study aimed to investigate the effects of RuBPY on the intracellular mobilization of calcium stores of rat aortic vascular smooth muscle cells. Vascular reactivity experiments were performed in isolated aortic rings that were contracted with a high concentration of KCl or phenylephrine (Phe). Moreover, primary cultured vascular smooth muscle cells were used to measure [Ca2+]c by confocal microscopy. The NO donor RuBPY decreased the [Ca2+]c and reduced KCl and Phe‐induced contractile responses. The selective inhibitor of sarco‐endoplasmic Ca‐ATPase (SERCA) with thapsigargin impaired the effect of RuBPY on Phe‐induced contractile response. RuBPY also reduced caffeine‐induced contraction, and the contraction dependent on the capacitive Ca2+ influx. Therefore, our results suggest that NO released from RuBPY decreased [Ca2+]c by calcium influx blockade and activation of guanylyl‐cyclase‐cGMP‐GK pathway. These results indicate that RuBPY increases Ca2+ storage in the sarcoplasmic reticulum by SERCA activation and also by capacitive Ca2+ influx inhibition, which is dependent on the intracellular release of nitric oxide from this compound.
Effects of health expenditures on infant and child mortality rates: A dynamic panel data analysis of 37 African countries
Authors: Houeninvo Hilaire Gbodja 
Published: May 2022

AbstractThis paper examines the effect of public and private health spending on health outcomes measured by infant and child mortality rate using a panel of 37 African countries over the period 1995–2018. Based on both system generalized method of moments and least squared dummy variable corrected bias estimators, we find that the level of public health expenditures has statistically significant positive effects on mortality reduction. However, private health spending has a statistically significant positive effect on infant and child mortality rates when it interacts with public health spending. This means that the health effect of private health expenditure is strengthened by public health spending. Conditioning on the level of private health expenditure, the total effect of public health expenditure on child mortality reduction is slightly higher in absolute value than that of private health expenditure. The main policy implication that emerges from our results is the need to increase public health expenditure and support the effectiveness of private health expenditure. This additional fund should be allocated to some specific expenditure categories which have a very direct link with child and infant mortality rates.

Corporate Tax Avoidance and Corporate Social Responsibility Disclosure Readability: Evidence from China
Authors: Xu Shuolei , Wang Fangjun , Cullinan Charles P. , Dong Nanyan 
Published: May 2022

AbstractPaying taxes to support the societies in which they operate is both a legal and ethical responsibility of business. Nevertheless, some companies work to avoid taxes, which could cause society to question the legitimacy of the organisation. Many companies provide reports on their corporate social responsibility (CSR) activities; more transparent CSR reports may help to restore the legitimacy loss associated with tax avoidance. We investigate the relationship between tax avoidance and CSR report readability among Chinese companies. We find a positive relationship between corporate tax avoidance and the readability of CSR reports. This relation is weaker among state‐owned enterprises, which may have stronger pre‐existing legitimacy owing to their relationship with the state. The relationship is also weaker among companies in less developed regions of China, which have less developed institutions to monitor organisational legitimacy. Overall, our results are consistent with the notion that CSR reporting represents an attempt to overcome legitimacy concerns arising from tax avoidance. Our findings indicate that tax avoidance and CSR reporting are alternative means of establishing legitimacy, rather than complementary reflections of an organisational culture that values (or devalues) CSR.

Published: May 2022

AbstractDietary folic acid augmentation during gestation reduces neurodevelopmental disorder risk in offspring; however, it is still unclear if excessive maternal folic acid intake can impair brain function in offspring. We examined if excessive folic acid intake throughout gestation altered the behavior of male offspring under poor nutrition during early gestation (E5.5–E11.5). Dams were divided into four groups: control (CON, 2 mg folic acid/kg of food), excessive folic acid fortification (FF, 10 mg folic acid/kg of food), undernutrition (UN, 40% food reduction from E5.5–E11.5), and excessive folic acid fortification plus undernutrition (UN‐FF). Excess maternal folic acid fortification induced hyperactivity in the open‐field and lower anxiety‐like behavior in the elevated plus maze at 9 weeks of age. These behavioral changes were accompanied by reduced dopamine in the prefrontal cortex (PFC), norepinephrine in the amygdala, and 5‐hydroxytryptamine (5‐HT) in the dorsal midbrain (DM), PFC, and amygdala where 5‐HT neurons project from the DM. Furthermore, canonical discriminant analysis, including dopamine and DOPAC concentrations in the PFC, norepinephrine concentrations in the PFC, amygdala, and pons, and 5‐HT and 5‐HIAA concentrations in the amygdala and DM, correctly classified 73.5% of the offspring in CON, FF, UN, and UN‐FF groups. The first discriminant function mainly classified groups based on nutritional status, whereas the second function mainly classified groups based on folic acid intake. Our study suggests that combined transformations of brain monoamine profiles by maternal undernutrition and excess folic acid intake is involved in the behavioral alteration of offsprings.
