Abstract
Purpose
Modern CAD systems facilitate the creation of any surface geometry imaginable, and complex surfaces for free-form grid shells are often represented by a set of Non-Uniform Rational B-Splines surface patches. But it remains an intractable issue how to generate high-quality grids on complex surfaces efficiently. To solve this issue, an automatic triangular mesh generation method is presented, based on bubble dynamics simulation and a modified Delaunay method.
Design/methodology/approach
A moderate amount of points are first distributed on a given surface. Next, by regarding the points as elastic bubbles with the same size and introducing the forces acting on bubbles, the motion control equations of bubbles are established. The equilibrium state of the bubble system is found by Verlet algorithm. Then, the Voronoi diagram on the surface is obtained by calculating the intersection between the surface and the three-dimensional (3D) Voronoi diagram of the centers of bubbles. Finally, a triangular mesh, Delaunay triangulation on the surface, is determined based on the dual change of the Voronoi diagram.
Findings
This method generates meshes on the surface directly, unlike mapping-based methods, avoiding the mapping distortion. Examples are given to demonstrate the successful execution of this method. The result also illustrates that this method is applicable to various surfaces in high automation level and resultant meshes are highly uniform and well-shaped.
Originality/value
Thus, this method provides the convenience for the geometry design of complex free-form grid structure.

Abstract
Learning outcomes
Learning objectives of this case is to understand the hairdressing industry and develop the sub-branding strategy. After reading this case and practicing in class, students should be able to understand this business and marketing terminology and apply them in the real world. Students will learn the branding strategies: brand extension, brand architecture and brand portfolio. Students will design (DS) the brand name for the new store.
Case overview/synopsis
Case synopsis Mr. Tai-Hua Teng (aka TR) was a hair artist and opened his first hair salon, vis-à-vis (VS), in 1989 using a high-end positioning strategy. VS focused on offering superb and diverse services to keep ahead of the competition rather than trying to undercut prices. VS hair salon had a solid foundation based mainly on the elite, celebrities and high-salary customers. In 2017, TR owned 16 stores (including one in Canada and two intern salons), 1 academy, 265 employees and 3 brand names. The three brand names were VS, DS and concept (CC). DS and CC were less known to the public, so now these two brands had been carried the parent name and were known as VS DS and VS CC. Quick cut hairdressing businesses were thriving because customers needed quick and cheap hairdressing services. Acknowledging the benefits of entering the highly competitive quick haircut market, TR began to contemplate the new brand name and services to offer. VS had adopted the brand house strategy but TR wondered if it was better to have an individual brand name when entering the quick haircut market. The sub-branding strategy carried the established quality assurance of VS but there was possible brand overlap. An individual new brand name might lack the well-established values from VS but it also showed the potential to reach different segments of customers. TR’s decision to make: a branded house or hybrid? This case showed a high-end hair salon facing the need for simplicity in the market and considered how to expand its business to the lower-end market. Keywords: hairdressing, brand extension and sub-branding strategy.
Complexity academic level
Level of difficulty: easy/middle level to undergraduate courses specific prerequisites: it is not necessary for students to prepare or read any marketing theory or chapters of the textbook. However, it would help a more in-depth discussion if students know the CCs of brand architecture, brand portfolio, brand extension and line extension.

Abstract
Purpose
The purpose of this paper is to reduce the drag loss and study the effects of operating conditions and groove parameters such as flow rate and temperature of automatic transmission fluid, clearance between plates, groove depth and groove ratio on the drag torque of a wet clutch for vehicles, parametric analysis of the drag torque model of wet multi-plate friction clutch with groove consideration.
Design/methodology/approach
Both experimental and numerical research was carried out in this work. Parametric groove models, full film lubrication flow model and pressure distribution model are established to investigate the effects of the grooves on drag torque of a wet clutch. Multigrid method is used to simplify the solution.
Findings
In this paper, a drag torque model of a wet multi-plate friction clutch based on the basic theory of viscous fluid dynamics is examined through experimental and numerical methods that take grooves into account, and the change trend of drag torque with operating conditions and groove parameters is analyzed.
Originality/value
Multigrid method is used to solve the governing equations, which simplifies the solution process because of the restrictions and interpolation operations between the adjacent layers of coarser and fine grids. These works provide insight into the effect regularity of operating conditions and groove parameters on drag torque of a wet multi-plate friction clutch. Furthermore, variable test conditions and sufficient experimental data are the main functions in the experimental research.

Abstract
Purpose
The purpose of this study is to further explore the effects of customer participation (CP) and service personal values (SPVs) on cruise customer satisfaction (CS) and customer loyalty (CL) by applying the empirical research approach.
Design/methodology/approach
A self-administered questionnaire was prepared and used to collect data. Exploratory factor analysis and structural equation modeling analysis was used to test the proposed model and hypotheses.
Findings
The empirical results indicate that CP positively influences SPVs, CS and CL. SPVs have a significant and positive impact on CS as well. Moreover, the study also finds that collectivism has a strong positive effect on CP. Price sensitivity negatively moderates the relationship among CP, CPV, CS and CL.
Research limitations/implications
The generalizability of the current study findings should be considered or scrutinized in light of the fact that limited samples and cross-sectional data were used. This limitation positions the findings as a continuation of the developing path toward a better understanding of customer behavior rather than a definitive conclusion.
Practical implications
The study results show that CP has a positive direct effect on SPVs, CS and CL. Even though many researchers have verified the importance and function of CP, there is a lack of literature, which assesses the influence of CP in a cruise industry context. By focusing on this gap, this research makes it feasible to empirically analyze the different effects of CP in relation to SPVs, CS and CL in Chinese cruise preferences.
Social implications
The study results suggest that CP is a new predictor of CS and CL in the cruise industry. Thus, creating a positive experience through participation is crucial. As customers are co-producers, it is beneficial for the cruise companies to raise labor productivity and reduce cost by guiding and stimulating them to take part in the service-producing process.
Originality/value
Based on the perspective of service-dominant logic, the purpose of this study is to shed light on the formation process of loyalty behavior of Chinese cruise tourists. The empirical results indicate that CP positively influences SPVs, CS and CL. SPVs have a significant and positive impact on CS as well. Moreover, the study also finds that collectivism has a strong positive effect on CP. Price sensitivity negatively moderates the relationship among CP, CPV, CS and CL.

La lealtad de los clientes chinos de cruceros: el impacto de la participación de los clientes y los valores personales del servicio
Objetivo
El propósito de este estudio es explorar, en profundidad, los efectos de la participación del cliente (CP) y los valores personales del servicio (SPV) en la satisfacción del cliente de cruceros (CS) y la lealtad del cliente (CL) aplicando el enfoque de la investigación empírica.
Diseño/metodología/enfoque
La obtención de datos se realizó a través de un cuestionario autoadministrado. El modelo y las hipótesis propuestas fueron contrastados a través del análisis factorial exploratorio (EFA) y el análisis de ecuaciones estructurales (SEM).
Resultados
Los resultados empíricos indican que la CP influye positivamente en los SPV, CS y CL. Los SPVs también tienen un impacto significativo y positivo en la CS. Además, el estudio también encuentra que el colectivismo tiene un fuerte efecto positivo en el CP. La sensibilidad al precio modera negativamente la relación entre CP, CPV, CS y CL.
Limitaciones/implicaciones de la investigación
La posibilidad de generalizar las conclusiones del presente estudio debe considerarse teniendo en cuenta que se utilizaron muestras limitadas y datos transversales. Esta limitación hace que los hallazgos avancen en la senda para una mejor comprensión del comportamiento del cliente y no sean una conclusión definitiva.
Implicaciones prácticas
Los resultados del estudio muestran que el CP tiene un efecto directo positivo en las SPVs, CS y CL. Aunque muchos investigadores han verificado la importancia y la función de la CP, falta literatura que evalúe la influencia de la CP en el contexto del sector de los cruceros. Al centrarse en esta carencia, esta investigación permite analizar empíricamente los diferentes efectos de la CP en relación con las SPVs, CS y CL en las preferencias de los cruceristas chinos.
Implicaciones sociales
Los resultados del estudio sugieren que la CP es un nuevo predictor de la CS y la CL en el sector de los cruceros. Por tanto, crear una experiencia positiva a través de la participación es crucial. Dado que los clientes son coproductores, es beneficioso para las compañías de cruceros aumentar la productividad laboral y reducir los costes guiándolos y estimulándolos a participar en el proceso de producción del servicio.
Originalidad/interés
Basado en la perspectiva de la lógica dominante del servicio, el propósito de este estudio es arrojar luz sobre el proceso de formación de la lealtad de los turistas chinos de cruceros. Los resultados empíricos indican que la participación del cliente (CP) influye positivamente en los valores personales del servicio (SPV), la satisfacción del cliente (CS) y la lealtad del cliente (CL). Los SPVs también tienen un impacto significativo y positivo en la CS. Además, el estudio también encuentra que el colectivismo tiene un fuerte efecto positivo en el CP. La sensibilidad al precio modera negativamente la relación entre CP, CPV, CS y CL.

Abstract
Purpose
As consumers read multiple reviews, so consumer review consistency is important. The purpose of this paper is to investigate the role of consumer review consistency in influencing attitudes toward brands by examining its underlying effect on consumers’ emotions after they read consistent consumer reviews. In addition, the moderation effect of hedonic and utilitarian purchase values on positive consumer emotions and attitudes toward brands is explored.
Design/methodology/approach
This study used a quantitative design in which 329 participants – undergraduate and MBA students at a university in Taiwan – were asked to complete online questionnaires. To generalize the results, the questions in the questionnaire were based on any consumer reviews that the participants had recently browsed.
Findings
Consumer review consistency positively influences attitudes toward brands. Positive emotions are also developed when reading consistent consumer reviews, and this positively influences consumers’ attitudes toward brands. However, positive emotions are not derived from consistent consumer reviews in all contexts. The results show that positive emotions work well when consumers shop using hedonic value. Positive emotions create positive consumers’ attitudes toward a brand when they shop using hedonic value, but this significant effect does not occur when consumers shop using utilitarian value.
Research limitations/implications
This study’s results suggest that only investigating the quality of a consumer review or other aspects of a single review might overlook the impact of consumer review consistency, as consumers read multiple reviews. Consumer review consistency plays an important role in brand effectiveness, as consumers form positive attitudes toward brands when they read consistent reviews. Positive emotions can strengthen consumers’ attitudes toward a brand. Moreover, positive emotions increase positive attitudes toward brands only when consumers shop using hedonic value. However, positive emotions do not enhance consumers’ attitudes if they shop using utilitarian value.
Practical implications
Rather than focusing on the quality of a single review, online shops should carefully consider consumer review consistency. Although positive reviews are better than negative reviews, it is quite difficult for every shop to maintain 100 percent positive reviews. Therefore, maintaining and offering quality products and services are rather important to acquiring more positive reviews. Online shops should consider experimental marketing strategies when managing online shops. The layout of online sites that show consistent consumer reviews can provide consumers with cues that shorten decision making, especially for products that consumers tend to shop for using hedonic value.
Originality/value
This research extends the previous consumer review literature. Previous research was focused mainly on the quality of consumer reviews or other aspects of a single review. This research shows that focusing a single consumer review is not sufficient, as consumers generally read more than one consumer review. In addition, the role of positive emotions as a mediator between consumer review consistency and attitudes toward a brand was investigated. Furthermore, the moderated mediation effect was applied to investigate the role of shopping value (hedonic vs utilitarian value) as a moderator of positive emotions’ mediation effect.
