Abstract
Purpose
The purpose of this study was to develop a TiAlSiCN coating with high bonding and hardness, ultra-low friction and good lubrication characteristics, which provided an experimental basis for the surface modification of YT14 cemented carbide cutting tools.
Design/methodology/approach
In this work, a TiAlSiCN coating was deposited on YT14 cemented carbide cutting tool through cathodic arc ion plating. The surface-interface morphologies, distributions of chemical elements, phases, bonding energy and surface roughness were analyzed using field emission scanning electron microscopy, energy-dispersive spectroscopy (EDS), X-ray diffraction, X-ray photoelectron spectroscopy and atomic force microscopy, respectively, and the coating the bonding strength were quantitatively characterized with a scratch.
Findings
The average COFs of the TiAlSiCN coating at 700°C, 800°C and 900°C were 0.68, 0.57 and 0.38, respectively, showing that the TiAlSiCN coating was an effective lubricant at a high temperature, and the wear rate of the coating increases with wear temperature. After wearing at 700°C, 800°C and 900°C, the Ti, Si and N elements form atom-poor regions, while Al forms an atom-rich region, showing that the oxides of Ti, Al and Si are formed to improve the wear resistance of the coating. The wear mechanism of TiAlSiCN coating at high temperatures was composed of abrasive wear and oxidation wear.
Originality/value
The friction-wear behaviors of TiAlSiN coating were investigated using an HT-1000-type high-temperature friction wear tester, and the worn tracks on the coatings were analyzed using an EDS plane scan, thus obtaining the wear mechanism of TiAlSiN coating.

Purpose
Amid rising concerns over unhealthy dietary habits and their impact on public health, this study aims to explore the role of avatars in promoting healthier eating and enhancing customer satisfaction in restaurants. By leveraging the theory of planned behavior (TPB) and nudge theory, this research sought to gain insights into consumer behavior and assess how digital innovations can encourage healthier food choices.
Design/methodology/approach
This study recruited 672 participants in the USA. Participants viewed a video featuring an avatar that informed them about available healthy food options, simulating a restaurant ordering scenario. Following the video, participants completed comprehensive online surveys. The collected data was analyzed using partial least squares structural equation modeling to assess the effectiveness and implications of the intervention.
Findings
The findings revealed that health consciousness, environmental awareness, social norms and perceived behavioral control significantly influence dietary habits. Restaurant health initiatives and avatar persuasiveness were found to encourage healthier food choices, improve customer satisfaction and loyalty and enhance electronic word-of-mouth. The study confirmed that avatars equipped with attributes such as competence, warmth, trustworthiness and credibility can be an effective digital nudge for consumers toward healthier dietary decisions.

Abstract
Guaranteed maximum price (GMP) and target cost contracting (TCC) with a pain‐share/gain‐share arrangement have been adopted to integrate the construction delivery process and motivate service providers to seek continuous improvements in project outcomes. However, there is still a lack of research evidence to evaluate the levels of success and lessons learned from these innovative procurement strategies. Based on the analysis of a series of in‐depth interviews on the perceptions of various relevant experienced industrial practitioners, this paper aims to explore the key attributes of GMP/TCC including the underlying motives, perceived benefits, potential difficulties, critical success factors, key risk factors involved and optimal project conditions for adopting GMP/TCC. The research findings are useful in assisting key project stakeholders in minimising the detriments brought about by potential difficulties in and maximising the benefits derived from implementing GMP/TCC concepts. The study is also significant in contributing to new knowledge and practical information of GMP/TCC applications and implementation, in both a national and international context.

Abstract
Reports on two studies conducted in Hong Kong, one in 1989, the other in 1994, to see if children’s socialization as consumers has changed in the intervening years. Formulates hypotheses, based on the earlier research, that children will receive spending money by the time they are four, that the amount will increase as they get older, children will spend money by the age of four, they will also save money, older children will visit more shops than younger children, and children will go shopping without parents by the age of four. Outlines the research methodology used – 318 questionnaires used for analysis, composition of the sample of respondents, demographics – and records how analysis of variance was used to make comparisons with data from the earlier study. Considers income, spending and saving attitudes in children, as well as how they spend and what they buy. Finds that, in 1994 (compared to 1989) children aged 6, 9, 10, 11 and 12 receive more money; 4, 7 and 10 year olds spend a higher percent of their income, saving has decreased for 4, 7 and 10 year olds, children’s real income has doubled since 1989, independent shopping trips seem to have been postponed until the child is 6 but co‐shopping with parents has increased for all ages; most shopping trips without parents focused on food stores and street vendors that were easily accessible from home, but purchasing behaviour has not changed significantly. Indicates that Hong Kong children are pursuing a western (US) model of spending income, rather than the Chinese model of saving, and that children are undergoing consumer socialization and consumer education – as evidenced by the single fact that in 1994 $161.8 million was spent in Hong Kong by children aged 4‐12.

Abstract
Using Social Network Analysis (SNA), this paper examines the inter-country airline logistics relationships in East Asia. Based on the flight schedule data, which has been gathered by the authors, the overall features of airline logistics structure and the specific roles of each airport could be more clearly examined.
The main results of this paper are as follows: Beijing has the highest Degree Centrality, but excluding the domestic lines, Incheon has the highest Degree Centrality, which would imply that a relatively high Centrality of logistics for China’s airports is due to the greater number of domestic lines. The focal hub status of Incheon airport is also supported by the fact that Incheon contains the highest Betweenness Centrality.
Secondly, evaluated by the types of brokerage role, Incheon has a remarkably strong role as a liaison, which means Incheon airport functions as a transfer hub between two different regions outside of Korea. However, considering only the to/from China airline links, Hong Kong has the highest score as a liaison. These conflicting results imply that as China’s airline transportation continuously increases, Hong Kong will become a strong rival to Incheon.
Thirdly, in the analysis of Structural Hole which functions the broker and acts as a hub by linking unconnected airports, Incheon has the highest possibilities as a hub airport. However, only considering to/from China airlines, Hong Kong would dominate Incheon.

Abstract
Purpose
Previous research has yielded inconsistent findings of the effects that task conflict has on creative outcomes, with some research finding a negative relationship but others holding a positive or even no significant relationship. Drawing on the too-much-of-a-good-thing effect approach, this paper aims to investigate the curvilinear relations between task conflict and creative idea generation as well as the mediating role of task reflexivity and the moderating role of task complexity.
Design/methodology/approach
Two studies were carried out to test the proposed relationship. In Study 1, multisource and lagged data collected from 533 employees and 140 corresponding supervisors were used to test the curvilinear relationship between task conflict and creative idea generation as well as the moderating effect of task complexity. In Study 2, the authors extended the findings by exploring the mediating effect of task reflexivity using a matched sample of 350 employees and 99 corresponding supervisors.
Findings
Task conflict had an inverted U-shaped relationship with creative idea generation, and task reflexivity partially mediated this relationship. Besides, this association was moderated by task complexity such that the curvilinear relationship was more pronounced for tasks with lower complexity.
Research limitations/implications
This study was more or less contaminated by common method variance because some variables were derived from the same sources. Also, task conflict might be necessitated to differentiate and more situational variables should be considered to draw a complete picture.
Practical implications
Managers should undertake conflict management according to the levels of task conflict and task complexity. At a lower degree of task conflict, managers might motivate employees to think more about task-related issues; at higher levels of task conflict, managers should act as conflict mediators to reduce the underlying negative effects, especially for simple tasks.
Originality/value
These findings could help us understand the boundary conditions under, and the underlying mechanisms by, which task conflict has an impact on creative idea generation.

Abstract
Purpose
The purpose of the study is to examine the effect of value co-destruction on customer citizenship and negative electronic word of mouth (e-WOM) behaviors. In addition, the study aims to determine the mediating role of tourist citizenship between value co-destruction and negative e-WOM behaviors.
Design/methodology/approach
By using a convenience sampling method, data were collected from 704 customers, who purchased their touristic products through co-creation. The exploratory and confirmatory factor analyses were applied to the data obtained to determine the factors that make up the dimensions in the research model. The partial least squares-structural equation modeling (PLS-SEM) was used to evaluate the relationship in the research model proposed in the study.
Findings
The results of the study indicated that value co-destruction had an effect on customer citizenship behavior and negative e-WOM. While the helping behavior of customer citizenship had an effect on negative e-WOM, the advocacy behavior of customer citizenship had no effect on negative e-WOM. However, this study found only an indirect mediation effect of helping behavior in the relationship between value co-destruction and negative e-WOM.
Research limitations/implications
The research examined the antecedent behaviors that cause value co-destruction and the effects of these behaviors on the outcomes of the holiday experience. This information then was combined in a model and evaluated in a holistic framework. Theoretically, the research helps us understand the impact of value co-destruction behavior on citizenship behavior and on tourists’ negative e-WOM tendency. The research examines value co-destruction behavior and its effect on holiday-experience outcomes simultaneously.
Practical implications
The research provides a framework that tourism enterprises can use to produce and offer value-attributing services for their customers and to manage dysfunctional and disruptive business processes and behaviors to reduce value co-destruction. The research also provides a new way for practitioners in the tourism sector to understand and generalize the behavioral changes of tourists caused by value co-destruction during and after their experience.
Originality/value
The paper contributes to an understanding of value co-destruction antecedents and outputs from the customer perspective. Further, the research provides information to tourism businesses to effectively and efficiently manage the value co-creation process and prevent value co-destruction. The findings of the study will provide useful suggestions that will contribute to researchers and sectoral representatives.

Co-destrucción de valor y comportamiento negativo de e-wom: el papel mediador de la ciudadanía de los turistas
Resumen
Objetivo/Propósito
La investigación ha examinado el efecto de la destrucción conjunta de valor en la ciudadanía del cliente y en los comportamientos negativos de e-WOM. Además, la investigación tuvo como objetivo determinar el papel mediador de la ciudadanía turística entre la co-destrucción de valor y los comportamientos negativos de e-WOM.
Metodología
Utilizando un método de muestreo por conveniencia, se recopilaron datos de 704 clientes que compraron sus productos turísticos a través de un proceso de cocreación. Se aplicaron análisis factoriales exploratorios y confirmatorios a los datos para determinar los factores que componen las dimensiones en el modelo de investigación. Se utilizó el modelo de ecuaciones estructurales de mínimos cuadrados parciales (PLS-SEM) para evaluar la relación en el modelo de investigación propuesto en la investigación.
Resultados
Los resultados de la investigación indicaron que la co-destrucción de valor afectó el comportamiento de ciudadanía del cliente y el e-WOM negativo. Mientras que el comportamiento de ayuda de la ciudadanía del cliente afectó al e-WOM negativo, el comportamiento de defensa de la ciudadanía del cliente no afectó al e-WOM negativo. La investigación, sin embargo, encontró un efecto de mediación solo indirecto: un comportamiento de ayuda en la relación entre la co-destrucción de valor y el e-WOM negativo.
Originalidad
El documento ayuda a explicar los antecedentes y los resultados de la co-destrucción de valor desde la perspectiva del cliente. Además, su información puede permitir a las empresas turísticas gestionar de forma eficaz y eficiente el proceso de creación conjunta de valor y evitar la destrucción conjunta de valor. Los datos de la investigación también proporcionarán sugerencias útiles a otros investigadores y representantes del sector.
Implicaciones Teóricas
La investigación ha examinado los comportamientos antecedentes que causan la destrucción conjunta de valores y los efectos de estos comportamientos en los resultados de la experiencia vacacional. Esta información luego se combinó en un modelo y se evaluó en un marco holístico. Teóricamente, la investigación nos ayuda a comprender el impacto del comportamiento de co-destrucción de valor en el comportamiento de la ciudadanía y en la tendencia negativa de e-WOM de los turistas. La investigación examina el comportamiento de co-destrucción de valor y su efecto en los resultados de la experiencia vacacional simultáneamente.
Implicaciones Gerenciales
La investigación proporciona un marco que las empresas turísticas pueden usar para producir y ofrecer servicios que atribuyan valor a sus clientes y para gestionar procesos y comportamientos comerciales disfuncionales y disruptivos para reducir la co-destrucción de valor. La investigación también proporciona una nueva forma para que los profesionales del sector turístico comprendan y generalicen los cambios de comportamiento de los turistas causados por la destrucción conjunta de valor durante y después de su experiencia.
Limitación e Investigación Futura
Esta investigación tiene varias limitaciones que podrían sugerir direcciones para investigaciones futuras. Se seleccionó como escenario de investigación a los clientes que compran experiencias turísticas a través de un proceso de co-creación. Por esta razón, los resultados de esta investigación podrían no aplicarse a otros turistas. Esta investigación también examinó la co-destrucción de valor solo desde el lado de la demanda. Además, la investigación proporcionó evidencia preliminar sobre las premisas y los resultados de los comportamientos de co-destrucción de valor en el contexto del turismo. Además, la investigación futura podría intentar ampliar el presente trabajo mediante la identificación de factores adicionales que pueden gestionar la destrucción conjunta de valor y otros resultados de la destrucción conjunta de valor para las empresas.
