Abstract

Purpose

This paper aims to provide a reliable and efficient numerical piston–cylinder design method and assess the effect of clearance on the piston-cylinder lubrication.

Design/methodology/approach

Numerical analyses of lubrication characteristics were performed for the piston–cylinder interface. The axial piston was numerically modeled, and the film pressure was calculated using the unsteady two-dimensional Reynolds equation. The behavior of the piston was analyzed by calculating the eccentricity satisfying the force and moment balance.

Findings

The secondary motion of the piston included numerically simulated several cycles until the piston behavior converged, and contact with the inner wall of the cylinder and friction region was estimated. Results showed that the piston–cylinder clearance affected the contact force, length of the contact region and leakage flow rate.

Originality/value

This result improves the understanding of the piston–cylinder lubrication and suggests considerations in terms of lubrication in clearance design.

This paper aims to propose a new scuffing model caused by the depletion of additives in boundary lubrication condition.

Abstract

Purpose

This paper aims to propose a new scuffing model caused by the depletion of additives in boundary lubrication condition.

Design/methodology/approach

The differential equation governing the distribution of additive content in the fluid film was used. This formula was derived from the principle of mass conservation of additives considering the consumption due to surface adsorption of wear particles. The occurrence of scuffing was determined by comparing the wear rate of the oxide layer with the oxidation rate.

Findings

If the additive becomes depleted while sliding, the scuffing failure occurs even at a low-temperature condition below the critical temperature. The critical sliding distance at which scuffing failure occurred was suggested. The experimental data of the existing literature and the theoretical prediction using the proposed model are shown to be in good agreement.

Originality/value

It is expected to be used in the design of oil supply grooves for sliding bearings operating under extreme conditions or in selecting the minimum initial additive concentration required to avoid scuffing failure under given contact conditions.

Abstract

Purpose

Brand origin (BO) has been suggested as an important determinant of brand evaluation and purchase intention. However, previous studies have indicated that consumers have limited knowledge and ability to recognize national origin of brands. The purpose of this paper is to assess brand origin recognition accuracy (BORA) and its relationships with brand evaluation and purchase intention in the Indonesian laptop market.

Design/methodology/approach

A convenient sample of 195 people in Daerah Istimewa Yogyakarta participated in the survey. They were given a list of 18 laptop brands (four local and 14 foreign brands) and were asked to identify their actual national origins.

Findings

The study found that consumers are more likely to misidentify than correctly recognize a true BO. This limited ability also has contributed to the low BORA scores for both local and foreign brands. Brand evaluation was found to be positively correlated with purchase intention. However, the current study could only find partial supports for the relationship between BORA scores and brand evaluation as well as purchase intention.

Practical implications

Many Indonesian consumers are unaware of the laptops’ BO, whether it is foreign or local. Companies need to inform, educate, and/or remind consumers of their brand’s true origin and avoid being associated with a weaker country image. Furthermore, despite all four Indonesian laptop brand names seem to use non-Indonesian names, only one brand gains a slightly better brand evaluation from favorable misclassification. It may suggest that the effectiveness of foreign branding strategy in the Indonesian laptop market is debatable.

Originality/value

This is one of the few studies examining BORA in Indonesia, the world’s fourth most populous country and the largest laptop market in Southeast Asia.

Abstract

Purpose

The objective of this study is to offer a longitudinal examination of country image, consumers’ brand origin recognition accuracy, and how their effects on brand evaluations have evolved over the last decade.

Design/methodology/approach

The authors compare data gathered in 2020 against data gathered in 2008. Each data set consists of more than 500 American consumers evaluating approximately 12 different brands from three separate industries (i.e. auto, television, and fashion).

Findings

The findings indicate that country image can evolve over time and that its effect on brand evaluation persists even when inaccurate brand origin associations are made. The study offers meaningful insights for managers in understanding how brands’ country associations affect corresponding brand attitudes.

Originality/value

Significant research attention has been focused on the effects of country image. However, longitudinal analysis of the same research questions has been rare. This study offers a valuable comparison of how several important country-image related issues have evolved over time.

Abstract

Purpose

Considering the increasing significance of corporate social responsibility (CSR) in the corporate world and the mixed findings of the financial implication of CSR investment in the financial economics literature, the purpose of this study is to examine the relationship between (im)material CSR investment and firm performance and the moderating role of airline type and economic conditions based on the stakeholder theory and institutional pressure argument.

Design/methodology/approach

This study uses a two-way random-effects model by firm and year along with using clustering coefficient estimation by firm to control for the possibility of inflated standard errors because of autocorrelation across years within a given firm.

Findings

This study finds that both material and immaterial CSR initiatives do not directly influence firm performance, but airline type and economic conditions do moderate the relationship. In specific, the study found that airlines’ investments in material CSR initiatives show an indifferent effect on firm performance between low-cost and full-service carriers and also between non-recessionary and recessionary periods. On the other hand, investments in immaterial CSR initiatives present different impacts on firm performance between low-cost and full-service carriers and between non-recessionary and recessionary periods. In details, the effect is more negative for low-cost carriers and recessionary periods than full-service carriers and non-recessionary periods.

Originality/value

This is the first empirical investigation of materiality for the airline industry in relation to firm performance using the industry-specific Materiality Map developed by the Sustainability Accounting Standards Board. Further, this study incorporates two additional moderators (airline type and economic conditions) to enhance the understanding of the proposed relationships between (im)material CSR and firm performance.

Abstract

Purpose

IT service management (ITSM) is a discipline for management and maintenance of IT-systems and is claimed to play a critical role in supporting and satisfying business requirements. However, from a customer perspective, ITSM is considered as being costly and the outcome is not always satisfactory. Measurements used to monitor and evaluate ITSM-processes are mainly suggested from a service provider perspective. The purpose of this paper is to suggest measurements for ITSM based on a customer perspective that can be used for improving questionnaires.

Design/methodology/approach

The SERVQUAL scale has been used as a base for suggesting customer-oriented measurements for the ITSM-field. The gathered qualitative empirical data consisted of customer feedback, in questionnaires, to five IT service providers in Sweden. Based on these empirical data, the SERVQUAL scale has been modified according to ITSM-specific customer requirements. The service providers represent the sectors: car construction, forest management, IT consultants, public sector and logistics.

Findings

The paper demonstrates three types of findings: confirmation of original SERVQUAL determinants that could be reused in the ITSM-field, modification of attributes of the SERVQUAL determinants to better fit in the ITSM-field, and development of new categories and new attributes. Moreover, the analysis of SERVQUAL in relation to the empirical data revealed that the SERVQUAL's original conceptual structure needed to be improved. The authors have added a third hierarchical level that supports a conceptual understanding.

Originality/value

The knowledge contribution consists of a developed SERVQUAL, adjusted to fit the ITSM-field, and a suggested new conceptual structure of SERVQUAL consisting of three concepts: determinant, category and attribute.

Abstract

Purpose

The purpose of this paper is to investigate the moderating role of employees’ self-experienced social responsibility perceptions in the relationship between employees’ community- and environment-oriented social responsibility perceptions and trust in an organization.

Design/methodology/approach

The corporate social responsibility (CSR) construct is examined in the context of stakeholders including the community, environment and employees. The study was carried out with 438 questionnaires gathered from four- and five-star hotels operating in Alanya, Turkey. The proposed model was tested with the partial least squares method of structural equation modeling. Multiple group analysis was performed to test the moderating effect.

Findings

Findings reveal that employees’ community- and environment-oriented social responsibility perceptions have a positive effect on trust in the organization. Based on the results of multigroup analysis, the effect of employees’ community-oriented social responsibility perceptions on trust in the organization was determined to be more prominent in the group of employees with high self-experienced social responsibility perceptions. However, the same moderating effect could not be determined in relation to environment-oriented social responsibility perceptions and trust in the organization.

Originality/value

Studies focusing on CSR activities were mainly examined at the macro level. Internal stakeholders’ returns to these activities were not sufficiently considered. Contrary to previous studies that examine the link between CSR perceptions measured with Carroll’s pyramid dimensions and organizational trust, the current study examined CSR perceptions with the stakeholder approach. Moreover, the study discovered one of the variables defined as the black box that differentiates the returns that employees provide to CSR activities.

Abstract

Purpose

The purpose of this paper is to investigate concepts that are used in depicting future visions of society, as afforded by technology, to map the extent of their use, examine the level of their dominance in different research areas and geographic boundaries, identify potential overlaps, analyse their longitudinal growth, and examine whether any of the identified concepts has assumed an overarching position.

Design/methodology/approach

In total, 14 concepts, each of which is used to depict visions of future information infrastructures, were identified. More than 20,000 scholarly documents related to 11 of these concepts (those with 20 or more documents) are analysed by various qualitative/quantitative methods.

Findings

The concepts most referred to are semantic web and ubiquitous computing (all years), and internet of things (Year 2013). Publications on some newer concepts (e.g. digital living, real world internet) are minimal. There are variations in the extent of use and preferred concepts based on geographic and disciplinary boundaries. The overlap in the use of these terms is minimal and none of these terms has assumed an overarching umbrella position.

Research limitations/implications

This study is limited to scholarly publications; it would be relevant to also study the pattern of usage in governmental communications and policy documents.

Social implications

By mapping multiplicity of concepts and the dispersion of discussions, the authors highlight the need for, and facilitate, a broader discussion of related social and societal implications.

Originality/value

This paper is the first to present a collective of these related concepts and map the pattern of their occurrence and growth.

Abstract

Purpose

Gastronomic festivals are important events to bring people together around food-themed activities. This study aimed at determining the relationships between festival quality, memorable food experience, loyalty, behavioral intention, hedonic well-being, and eudaimonic well-being. In this study, festival quality is the independent variable that affects the memorable food experience, the memorable food experience is the independent variable that affects loyalty, and loyalty is the independent variable that affects behavioral intent. Hedonic well-being and eudaimonic well-being are moderating variables. Behavioral intention is the dependent variable, while memorable food experience and loyalty are both dependent and independent variables.

Design/methodology/approach

The population consisted of local tourists visiting Orange Blossom Carnival held in Adana, Turkey. The survey technique and the convenience sampling method were preferred and 545 data were obtained.

Findings

The analysis results showed that all dimensions of the memorable food experience are strongly affected by festival quality. Plus, superior service approach and high value perception dimensions of the memorable food experience have significant effects on loyalty. Furthermore, destination loyalty was found to have a strong effect on behavioral intentions. Moreover, higher levels of Hedonic well-being (HWB) and Eudomenic well-being (EWB) were found to increase the effect of loyalty on behavioral intention; accordingly, the moderator roles of HWB and EWB were determined.

Practical implications

This article provides information that the memorable dining experiences of festival visitors who attend the Orange Blossom Carnival in Adana affect the quality of the festival and their intentions to loyalty. In addition, in the study, it was found that the well-being of carnival visitors had a moderating role in the effect of their loyalty on their behavioral intentions. Therefore, this article provides information on how the food experiences and well-being of the visitors at the gastronomy festival will affect which factors.

Originality/value

According to the findings, gastronomy-based events may affect tourists’ experiences, and tourists’ psychological well-being affects loyalty and behavioral intentions. Destination management organizations can learn about gastronomy-based festivals. The results of the study include a number of theoretical and practical findings for destination management organizations, festival managers, policy makers and academics working in the literature.
