Abstract
Using ABA research design and daily indices from South Africa, Eurozone, Japan and the United States of America, this study evaluates the interaction between equity index futures and spot markets before; during and after the COVID-19 pandemic. The results show evidence of cointegration between the equity futures and spot markets before, during and after the COVID-19 pandemic, a unidirectional causal relationship from the equity spot to the futures markets before and after the COVID-19 era, and bidirectional causality between the equity spot and futures markets during the COVID-19 pandemic, except for the South African markets. The results also show evidence of more spikey volatility during the COVID-19 pandemic era than was the case before and after the pandemic and the existence of bidirectional volatility transmission between the markets. The magnitude of transmission was stronger from the spot to futures markets during the COVID-19 pandemic era. Overall, the results suggest that the interaction between equity futures and spot markets varies according to the prevailing economic condition and the level of development of the markets.

Abstract
Purpose
Many industries use non-Newtonian ternary hybrid nanofluids (THNF) because of how well they control rheological and heat transport. This being the case, this paper aims to numerically study the Casson-Williamson THNF flow over a yawed cylinder, considering the effects of several slips and an inclined magnetic field. The THNF comprises Al2O3-TiO2-SiO2 nanoparticles because they improve heat transmission due to large thermal conductivity.
Design/methodology/approach
Applying suitable nonsimilarity variables transforms the coupled highly dimensional nonlinear partial differential equations (PDEs) into a system of nondimensional PDEs. To accomplish the goal of achieving the solution, an implicit finite difference approach is used in conjunction with Quasilinearization. With the assistance of a script written in MATLAB, the numerical results and the graphical representation of those solutions were ascertained.
Findings
As the Casson parameter
Originality/value
There is no existing research on the effects of Casson-Williamson THNF flow over a yawed cylinder with multiple slips and an angled magnetic field, according to the literature.

Abstract
Purpose
The purpose of this paper is threefold. First, it aims to clarify the moderating role of self-esteem (SE) and susceptibility to normative influence (SNI) in the relationship between brand love and brand loyalty. Second, the study proposes modeling the mediation role of brand love and outlining how SE and SNI affect the consumer-brand relationship. Finally, the study explores the impact of brand love on brand loyalty: the moderating role of self-esteem and social influences, as the literature regarding this is still lacking.
Design/methodology/approach
Data were collected via an online survey, which yielded 218 responses. Structural equation modeling was used to predict the research model.
Findings
The findings indicate that both SE and SNI mediate the relationship between brand love and brand loyalty. Additionally, consumers love the focal brands positively relates to SE and SNI. In return, SE and SNI lead to brand loyalty. The tight relationship of SE and SNI affects the connection between brand love and brand loyalty.
Research limitations/implications
The data has been collected in Vietnam, which creates a limitation regarding the study’s cross-cultural nature and the economic context. Thus, the study should be conducted in different cultures and economies (both developing and developed countries) to enhance the generalizability in consumer-brand relationships.
Practical implications
Brand managers should conduct more advertising in brand communities to enhance the influence of SNI and emphasize unique features of the brands, to attract consumers through the overlap of SE.
Social implications
The findings can contribute to enhancing unique brand identity and self-motivation will increase consumer loyalty, increasing the revenue of a specific brand. Moreover, as acceptable peers contribute to making purchase decisions, boosting the brand community will maintain current consumers and attract additional potential consumers from the current consumer relationships.
Originality/value
This study contributes to consumer psychology by indicating both SNI and SE as the mediators in the relationship between brand love and brand loyalty and how the consumer-brand relationship can be enabled.
Propósito
El propósito de este trabajo es triple. En primer lugar, pretende aclarar el papel moderador de la autoestima (SE) y la susceptibilidad a la influencia normativa (SNI) en la relación entre el amor y la lealtad a la marca. En segundo lugar, el estudio propone modelar el papel mediador del amor a la marca y esbozar cómo la autoestima y la SNI afectan a la relación consumidor-marca. Por último, el estudio explora los factores que afectan a la relación entre el amor a la marca y la lealtad a la misma, ya que aún no existe literatura al respecto.
Diseño/metodología/enfoque
Los datos se recogieron mediante una encuesta en línea, que arrojó 218 respuestas. Se utilizó el modelo de ecuaciones estructurales (SEM) para predecir el modelo de investigación.
Hallazgos
Los hallazgos indican que tanto la autoestima como la SNI median la relación entre el amor y la lealtad a la marca. Además, el amor de los consumidores por las marcas focales se relaciona positivamente con la autoestima y la SNI. En cambio, la autoestima y la SNI conducen a la lealtad a la marca. La estrecha relación de la autoestima y la SNI afecta la conexión entre el amor a la marca y la lealtad a la misma.
Limitaciones de la investigación
Los datos se han recogido en Vietnam, lo que crea una limitación en cuanto a la naturaleza transcultural del estudio y el contexto económico. Así pues, el estudio debería realizarse en diferentes culturas y economías (tanto de países en desarrollo como desarrollados) para aumentar la posibilidad de generalización en las relaciones entre consumidores y marcas.
Implicaciones prácticas
Los gerentes de marca deberían hacer más publicidad en las comunidades de marcas para aumentar la influencia de la SNI y hacer hincapié en las características singulares de las marcas, a fin de atraer a los consumidores mediante la superposición de la autoestima.
Implicaciones sociales
Las conclusiones pueden contribuir a mejorar la identidad de una marca única, y la automotivación aumentará la lealtad de los consumidores, incrementando los ingresos de una marca específica. Además, como los pares aceptables contribuyen a la toma de decisiones de compra, el impulso de la comunidad de marcas mantendrá a los consumidores actuales y atraerá a otros consumidores potenciales de las relaciones de consumo actuales.
Originalidad/valor
Este estudio contribuye a la psicología del consumidor al indicar que tanto la SNI como la autoestima son los mediadores en la relación entre el amor y la lealtad a la marca y la forma en que se puede habilitar la relación consumidor-marca.

Abstract
Purpose
Reynolds-averaged Navier–Stokes (RANS) models often perform poorly in shock/turbulence interaction regions, resulting in excessive wall heat load and incorrect representation of the separation length in shockwave/turbulent boundary layer interactions. The authors suggest that this can be traced back to inadequate numerical treatment of the inviscid fluxes. The purpose of this study is an extension to the well-known Harten, Lax, van Leer, Einfeldt (HLLE) Riemann solver to overcome this issue.
Design/methodology/approach
It explicitly takes into account the broadening of waves due to the averaging procedure, which adds numerical dissipation and reduces excessive turbulence production across shocks. The scheme is derived based on the HLLE equations, and it is tested against three numerical experiments.
Findings
Sod’s shock tube case shows that the scheme succeeds in reducing turbulence amplification across shocks. A shock-free turbulent flat plate boundary layer indicates that smooth flow at moderate turbulence intensity is largely unaffected by the scheme. A shock/turbulent boundary layer interaction case with higher turbulence intensity shows that the added numerical dissipation can, however, impair the wall heat flux distribution.
Originality/value
The proposed scheme is motivated by implicit large eddy simulations that use numerical dissipation as subgrid-scale model. Introducing physical aspects of turbulence into the numerical treatment for RANS simulations is a novel approach.

Abstract
Purpose
Customer value co-creation behavior is promising but undertheorized. To bridge this gap, this study examines the viability of a social cognitive theory positing that customers' value co-creation behavior is shaped by their co-creation experience, self-efficacy, and engagement.
Design/methodology/approach
Using healthcare as a case, a stratified random sample comprising 600 patients from 40 hospitals across eight metropolitan cities in an emerging economy was acquired and analyzed using co-variance-based structural equation modeling (CB-SEM).
Findings
Customers' co-creation experience has a positive impact on their co-creation self-efficacy, co-creation engagement, and value co-creation behavior. While co-creation self-efficacy and engagement have no direct influence on value co-creation behavior, they do serve as mediators between co-creation experience and value co-creation behavior, suggesting that when customers are provided with a co-creation experience, it enhances their co-creation self-efficacy and engagement, ultimately fostering value co-creation behavior.
Originality/value
A theory of customer value co-creation behavior is established.

Abstract
Purpose
The purpose of this paper is twofold. First, we map the emerging climate narratives from the 1970s. Second, we examine how these narratives have shaped climate governance in addressing the consequences of climate change. Our analysis is based on a set of 12 interviews with climate change experts from various fields, including climate science, environmental policy, and environmental sustainability. The theoretical framework primarily draws from narrative analysis (Bruner, 1991; Riessman, 2005; Freeman, 2015), with a specific emphasis on its application within climate change studies (Bottici, 2010; Bushell et al., 2015; Fløttum and Gjerstad, 2017).
Design/methodology/approach
The period of analysis starts from the 1970s. A period marked by growing concern and the creation of national and global organizations to address the effects of climate change. Semistructured interviews were conducted with a sample of 12 experts in the field using narrative analysis. We adopted an inductive approach, allowing climate narratives to emerge organically from the interview data, and facilitating the emergence of new topics and perspectives.
Findings
Through interviews with climate experts, this study identifies three key narratives and critical shortcomings related to climate governance. The dominant climate narratives identified are apocalyptic environmentalism, greening capitalism and degrowth. Notably, greening capitalism and degrowth emerge as a dichotomous framework for understanding and interpreting climate change. By exploring these climate narratives, we highlight five critical shortcomings related to climate governance: increasing citizen participation through a bottom-up governance model, reforming the environmental subsidy framework, strengthening the science-policy interface, decoupling economic growth from energy dependence and developing innovative technological models beyond traditional green growth approaches. As a result, climate governance remains confined to these binary frameworks, and the challenges that were promised to be addressed decades ago largely remain unresolved.
Originality/value
The value of this study lies in the fact that, on the one hand, it uses narrative analysis to investigate climate governance, and on the other hand, it does so through interviews with different actors. All this facilitates a holistic approach, and from a 50-year historical perspective, this study traces an evolutionary line of narratives and identifies the critical points of climate governance.

Abstract
Purpose
Product trials are an effective way to influence consumer attitudes. While research has established several factors that influence whether consumers will try a product or not, it is less understood how marketers can optimize the trial experience itself. The purpose of this paper is to explore flow as an optimal state and the factors that give rise to it during a product trail.
Design/methodology/approach
This research consists of three experimental studies in which people trial new music. This paper explores the ability of curiosity to optimize consumers’ flow experience during the trial and their attitudes toward the trialed product. This paper manipulates curiosity before the trial using information about the music (Study 1) and music previews (Study 3) and also demonstrates that curiosity is naturally elevated among those high in openness to experience (Study 2).
Findings
The results demonstrate that curiosity before a product trial fosters an optimal experience during the trial in the form of flow states, defined as an enjoyable state of full engagement, which in turn mediates more positive attitudes toward the trialed product. This paper demonstrates that curiosity can be evoked using product information or a preview of the content and can vary based on individual differences in openness to experience. The relationship between curiosity and flow is moderated by the valence of the information that is used to elicit curiosity, such that negative-valence information thwarts the relationship.
Research limitations/implications
While the studies conducted by the authors focus on the positive influence of curiosity in the trial of music, the effects may be different for other products. These studies are also limited to two different manipulations of curiosity.
Practical implications
This research has implications for marketers, as it demonstrates the relevance of flow and how to enable it in product trials to optimize effectiveness. The manipulations also demonstrate how to manage the amount of information that is given to consumers before they trial a product.
Originality/value
This research reveals that flow states optimize the product trial experience. This research also advances the understanding of the relationship between curiosity and flow by moderating their relationship with the valence of information that elicits curiosity. The findings also broaden the relevance of curiosity and flow in marketing by demonstrating their benefits within product trials.

Abstract
Purpose
Mangrove forests are one of the most bio-diverse and productive wetland environments on earth. However, these unique tropical forest environments that occupy coastal areas are among the most threatened habitats globally. These threats include logging, conversion of land for agriculture and mariculture and degradation due to pollution over the past 50 years. The large population of resilient mangroves occupying the Turneffe Atoll area in Belize faces growing anthropogenic threats such as permanent clearing of land for housing, infrastructural development and pollution and natural factors (climate change). Given the few formal studies done to evaluate mangrove resilience at Turneffe Atoll, the purpose of this study was to evaluate mangrove resilience and nursery functions in the Turneffe Atoll Marine Reserve (TAMR).
Design/methodology/approach
Mangrove fish abundance and forest structure was assessed by means of a visual census and the point-centred quarter method (PCQM) for 11 sites that span across conservation and general use zones.
Findings
This study found that the more resilient mangroves (lower vulnerability ranks, higher standing biomass and higher fish biomass and abundance) exist in general use zones and warrant the need for improved mangrove conservation measures for these areas by Turneffe Atoll Sustainability Association (TASA).
Research limitations/implications
Limitations of the methods for data collection included accessibility within mangrove forests stands when establishing PCQM, observer bias among data collectors, sites without surrounding mangroves were not captured to serve as a true control group and poor visibility underwater affected the estimation of fish species and size. The timeline for this research was only three months based on available funding, and no follow-up study was done to make a true comparison.
Originality/value
The findings of this research have a guiding role in the formulation of conservation measures such as better waste management, a robust framework for mangrove management, a communication strategy to guide public awareness and long-term monitoring surveys.

Abstract
Purpose
This paper investigates the impact of education on output of rice farming households in Vietnam.
Design/methodology/approach
Given the literature review, this paper specifies three empirical models (i.e. linear constant coefficient model, partially nonlinear model and linear varied coefficient model) with variables that well describe the mechanism through which education affects output. The data were collected from 901 rice farming households randomly selected out of ten provinces and city in the Mekong River Delta (MRD) of Vietnam. The models are estimated using ordinary least squares (OLS) and Robinson's (1988) double residual estimators.
Findings
Estimates of the empirical models show that seed, fertilizer, labor and farm size have significant impacts on output of rice farming households while pesticide and herbicide do not. Education is also found to have a positive effect on output of rice farming households because it helps them better manage farms of larger size via combining various inputs in a more desirable way.
Originality/value
This paper confirms the positive impact of education on agricultural output, which implies that policies aiming to provide better education to rural people will greatly enhance their income as well as trigger long-term economic and agricultural growth.

Abstract
Purpose
The study aims to examine the factors affecting the customers' choice of Bangladeshi banks during the Covid-19 pandemic and the moderating effects of private and public banks on this association.
Design/methodology/approach
This study is based on explanatory research, where significant factors have been explored to evaluate the customers' perception of private and public banks in Bangladesh. Primary data are accumulated through an online survey from customers who have an account in a private or public bank in Bangladesh during the past four months, where 318 (non-probability convenience sampling) are usable, and secondary data are collected from various sources. Descriptive statistics, multiple and hierarchical multiple regressions have been conducted.
Findings
The results revealed that customers consider safe and secure websites, infrastructural facilities, technological know-how, service, price, time, payment, administrative and psychological factors in choosing Bangladeshi banks during Covid-19. Moreover, the results show that private and public banks have moderated these associations.
Originality/value
During Covid-19, few studies were conducted on Pakistani, Sri Lankan and Ethiopian banking customers, where different factors are significant; however, this study is unique because all factors are significant for Bangladeshi banking customers. The findings will originate the value with several theoretical implications and managerial guidelines.
