This paper aims to improve Reynolds-averaged Navier Stokes (RANS) turbulence models using a data-driven approach based on machine learning (ML). A special focus is put on determining the optimal input features used for the ML model.

The field inversion and machine learning (FIML) approach is applied to the negative Spalart-Allmaras turbulence model for transonic flows over an airfoil where shock-induced separation occurs.

Optimal input features and an ML model are developed, which improve the existing negative Spalart-Allmaras turbulence model with respect to shock-induced flow separation.

A comprehensive workflow is demonstrated that yields insights on which input features and which ML model should be used in the context of the FIML approach

This paper aims to model and estimate how celebrity chief executive officers (CEOs) credibility (i.e. expertise, trustworthiness, attractiveness) is related to their brand image (i.e. functional, sensory/visual). This paper further examines the effects of consumer materialism on both celebrity CEOs’ credibility and the image of their brand.

A total of 260 participants knowledgeable of CEOs and their corresponding brands completed an online questionnaire in a cross-sectional study. The data were analyzed through covariance-based structural equation modeling.

Celebrity CEOs’ expertise and attractiveness are positively related to both functional and sensory/visual images of their brands. Results also demonstrate the positive effect of materialism on both celebrity CEOs’ credibility and brand image.

The research was conducted in one country (France) using a cross-sectional design. Additional studies in other settings or countries should be carried out to establish the generalizability of results and strengthen causality inferences.

CEOs need to understand and manage their key role as celebrities, given the direct influence they may have on consumer brand perceptions and behavior.

This study refines the relationship between celebrity CEOs’ credibility and brand image. It is the first to introduce and validate the effect of consumer materialism on the perception of celebrity CEOs.

This paper aims to extend the understanding of how global brands can positively influence brand trust by introducing two new mediating variables – brand affect and brand innovativeness, and testing the moderating role of consumer ethnocentrism in these relationships.

In total, 250 participants completed self-administered online questionnaires in a cross-sectional study in France. Moderated mediation and floodlight analysis were performed.

Brand globalness is positively related to brand affect and this, in turn, is positively related to brand trust. The relationship between brand globalness and brand affect is weaker for ethnocentrist consumers. Brand globalness is positively related to brand innovativeness and this, in turn, is positively related to brand trust. The relationship between brand globalness and brand innovativeness is weaker for ethnocentrist consumers.

A limited number of fast-food brands was analyzed. Future studies should replicate the research model using different product categories to generalize the findings.

This study offers new opportunities for managers concerned by the optimization of their global brands management. First, the results demonstrate the interest of managers to increase the emotional and affective aspects of their global brands to make them more trustable. Second, brand managers should also emphasize the innovative aspects of their global brand. Indeed, it is essential for practitioners not only to propose frequently new and innovative products to consumers but also to follow the latest trends in their market. The more managers provide new, useful solutions to fulfill consumers’ needs, the more consumers will trust those global brands.

The mediating role of brand affect and brand innovativeness in the relationship between brand globalness and brand trust gives new insights on an established relationship.

The purpose of this study is to examine how brand attachment is related to brand experience. The model tests the partial mediating role of brand trust and the moderating role of age and income.

A total of 334 participants consuming brands with an experiential offering completed an online questionnaire in a cross-sectional study. The data were analyzed through partial least squares structural equation modeling (PLS-SEM), and advanced methods such as the heterotrait–monotrait ratio and the Henseler’s multigroup analysis were used.

Brand experience is positively related to brand attachment, more so for younger consumers. This relationship holds for both hedonic and utilitarian brands. Results demonstrate the partial mediation of brand trust in this relationship, especially for utilitarian brands, and with a weaker indirect relationship for high-income consumers.

The research was conducted in one country (Peru). Generalizability of results should be established by carrying out additional studies in other settings or countries.

Experiential marketing both as a positioning strategy and through marketing operations may help brands to increase consumer attachment. This may be managed both through the direct effect of favoring positive experiences and through the enhancement of brand trust. This is particularly the case for target markets composed of young and low-to-medium-income consumers.

Results confirm the impact of brand experience on brand attachment for both utilitarian and hedonic brands, and establish both the mediating role of brand trust and the moderating role of age and income. These are new insights on the process itself and on boundary conditions of an important established relationship.

Very limited research exists examining envy from the viewpoint of an envied consumer, rather than an envier. This paper aims to address this gap by examining whether and how the experience of being envied actually affects consumers.

This paper presents three experiments. Study 1 investigates the ambivalent experience of being envied. Study 2 examines the effect of being envied in consumption contexts on consumer satisfaction, analyzing the combined ambivalent effects of positive and negative feelings. It also investigates the moderating role played by consumer coping responses to enviers (mitigation vs exacerbation). Finally, Study 3 applies the hypothesized model in a specific context (i.e. a material possession context), focusing on adult consumers.

Results show that negative (e.g. guilt and anxiety) and positive (e.g. sense of well-being and prestige) feelings for being envied depend on the type of relationship between the envier and the envied, and the type of desired object, and consumer satisfaction is driven by the combined ambivalent effects of positive and negative feelings, where coping responses by envied consumers moderate the effects of such feelings on satisfaction.

This paper makes three main contributions: it extends prior research by highlighting the role of personal relationship factors and the type of object of desire in the experience of being envied; demonstrates that both positive and negative feelings of being envied affect consumer satisfaction; and shows conditions regulating the influence of positive and negative feelings on satisfaction, demonstrating that mitigation strategies decrease the effects of negative feelings on satisfaction, whereas exacerbation strategies failed to regulate the effects of positive feelings.

This paper aims to focus on brand oldness associations and their measurement. Research on brand age points to a variety of interpretations concerning perceived brand oldness and establishes the existence of multiple positive consequences such as brand credibility, trust or attachment. However, the complexity and measurement of brand oldness associations are not yet well-established. This paper proposes a reliable and valid measurement scale of the concept.

The research follows a rigorous scale-development procedure based on eight empirical studies, with a total of 2,065 respondents. The data were analyzed through covariance-based structural equation modeling.

The scale consists of 18 items and six dimensions, namely, decline, expertise, maintenance, reminiscence, timelessness and tradition. Results demonstrate an effect of brand oldness associations on both brand attachment and brand equity.

The research was conducted in one country (France). Additional studies in other settings or countries should be carried out to establish generalizability of results and strengthen causality inferences.

This is the first research to study the notion of brand oldness associations. This study identifies its dimensions, develops a measurement scale and demonstrates its reliability and validity.

In 1967, Robert N. Bellah famously argued that there existed an “American Civil Religion,” which was distinct from churchly religion and captured the “transcendental” dimension of the American project. In this chapter, I revisit the civil religion concept and reconstruct it along more Weberian lines. Specifically, I argue that the civil religion tradition is one of three competing traditions for thinking about the proper relationship between religion and politics in America; the other two are religious nationalism and liberal secularism. Whereas liberal secularism envisions a complete separation of the religious and political value spheres, and religious nationalism longs for their (re)unification, civil religion aims for a mediating position of partial separation and productive tension. Following Bellah, I argue that the two central strands of the civil religion tradition have been covenant theology and civic republicanism. The body of the chapter sketches out the development of the tradition across a series of national foundings and refoundings, focusing on the writings of leading civil theologians from John Winthrop and John Adams through Abraham Lincoln and John Dewey to Martin King and Barack Obama. The conclusion advances a normative argument for American civil religion – and against liberal secularism and religious nationalism. I contend that liberalism is highly inclusive but insufficiently solidaristic; that religious nationalism is highly solidaristic but insufficiently inclusive; and that only civil religion strikes a proper balance between individual autonomy and the common good.
