Abstract
Progress in machine building is connected with computer integrated manufacturing (CIM) development. An essential part of CIM is a computer aided design (CAD) system for off‐line creation of manufacturing control programs. Each technological process is characterised by special equipment and operations, which complicate development of CAD off‐line programming systems. More than 90 robot programming systems and languages are now in existence. However, programming all technological aspects into one single CAD system is not possible so far; besides, a teaching method being required, the programs contain many operators, and the database of CAD/CAM is not sufficiently used.

Abstract
Purpose
The objective of this study is to explore adolescent girls' knowledge about the types of beauty valued in contemporary American popular and commercial culture.
Design/methodology/approach
Eighty girls ranging from seven to thirteen years old participated in a card sorting and collage construction exercise using 47 advertisements that featured models.
Findings
Differences were found among girls according to age. Preferred beauty types were more complex with age. Furthermore, older girls made more product and brand associations.
Research limitations/implications
The findings indicate that the beauty match‐up hypothesis holds among young girls.
Practical implications
Advertisers may be overlooking the audience of young women by neglecting to use models who represent their desired type(s) of beauty. They may even be alienating young girls by using anti‐ideals such as nudity and sexiness. Furthermore, advertisers must use models who convey the appropriate personality traits to create persuasive ads.
Originality/value
This study is important because it expands upon previous work that has assessed how and why young girls are affected by highly attractive models in ads. However, instead of conceptualizing physical attractiveness as a simple bipolar continuum from “attractive or pretty” to “unattractive or ugly”, this work considers the complex, multidimensional properties of beauty.

Abstract
Purpose
This study aims to investigate the causes of leakage in radial oil seals under dynamic eccentricity, elucidate the influence of operating parameters on leakage failure and develop methods for predicting and preventing such leakage.
Design/methodology/approach
Based on the principle of cam motion and considering viscoelasticity, develops a motion model of the compression and release of the shaft seal and proposes a method to determine its failure. In addition, this study quantifies the leakage gap and formulates a quantitative calculation model to accurately determine the location and shape parameters of the leakage gap.
Findings
Leakage gaps predominantly occur during the release phase of the shaft seal. Their presence can be identified by comparing the descending times of the seal and the shaft during this phase. An increase in rotation speed and eccentricity heightens the likelihood of gap formation, with both the dimensions and leakage rate of the gap increasing as these factors escalate. Eccentricity, in particular, has a more pronounced effect on gap formation.
Originality/value
This study clarifies the failure mechanisms of radial oil seals under dynamic eccentricity and introduces a criterion for identifying leakage gaps, providing valuable theoretical guidance for the design and optimization of radial oil seals.

Abstract
Purpose
There are ten universal principles of United Nations Global Compact in four areas namely human rights, labour, environmental and anti-corruption, and this chapter will explore the sixth principle of labour standard on elimination of discrimination in employment and occupation, in particular the doctrine of constructive dismissal in Malaysian labour relations. Constructive dismissal is creating a new challenge in labour relation in Malaysia.
Methodology/approach
This chapter specifically analyses some of the constructive dismissal awards and its implication to labour relations in Malaysia. The methodology employed in this chapter is the analysis of case laws using criterion-based sampling from the Industrial and Superior Court awards on constructive dismissal.
Findings
There has been an increasing number of awards on constructive dismissal made by the Malaysian Industrial Court over the last nine years. From the year 2009–2013, the Industrial Court has made 663 awards on constructive dismissal, mostly against employers. With compensation awarded to each employee amounted to as much as 24 months of back-pay salary plus a month’s pay for every year of service, employers can no longer neglect this pressing issue.
Research limitations/implications
The concept of constructive dismissal falls within the purview of section 20 of the Industrial Relations Act 1967 in Malaysia. Constructive dismissal is a ‘deemed dismissal’ if an employer is guilty of a breach of the employment contract which goes to the root of the contract. It arises when a workman terminates his/her contract of employment and considers himself/herself discharged from further obligations because of the employer’s conduct.
Practical implications
With a good understanding of the constructive dismissal awards, it is expected that organizations will manage and treat their human resources as their greatest assets and prevent constructive dismissal claims from taking place. This will eventually help to improve and maintain harmonious labour relations. This chapter is likely to provide insights into the Malaysian labour relations environment for international business operations.
Originality/value
In the context of Malaysian labour relations, studies on constructive dismissal are limited as it is considered as a new area and a specific area of study. This chapter therefore hopes to fill the existing gap in the literature, to highlight some of the recent awards and lessons to prevent constructive dismissal claims from taking place and generally to contribute to the constructive dismissal literature.

Abstract
The fast pace of business diversification, the “I and me” work ethic, and 1980s entrepreneurship have been superseded by downsizing, teaming, and total quality management. Some managers, who believe that finding the “right” or “strong” culture enhances corporate effectiveness, attempt to conceptualize the culture of organizations. This study examines employees’ perceptions of today’s organizational culture. The assumption here is that organizational culture in the 1990s has changed when compared to the 1980s era of diversification, mergers, and entrepreneurship. This study provides evidence that the emphasis on external stakeholders’ interest has led to so much downsizing that employee loyalty is adversely affected. As a result, organizations are not meeting the increased need for teamwork and problem‐solving.

Abstract
Purpose
The purpose of this paper is to predict the unstable cavitation shedding flow around a 2D Clark-y hydrofoil.
Design/methodology/approach
The paper studies Partially Averaged Navier-Stokes (PANS) model which was employed in the two-phase flow with a homogeneous cavitation model.
Findings
Maximum density ratio affects the mass transfer rate between the liquid and the vapor significantly. The cavitating flow predicted by PANS model can resolve more turbulent scales by decreasing the parameter fk.
Originality/value
The accuracy of numerical prediction is improved by increasing the maximum density ratio and decreasing fk.

Abstract
Purpose
This paper critically examines the effectiveness of male anchor in cross-gender endorsements and questions whether it can truly deliver positive outcomes for advertisers in the context of live streaming. It explores the underlying mechanisms of this effect by examining the mediation effect of perceived gender-identity incongruence and the moderation effect of anchor presence.
Design/methodology/approach
Three experiments are conducted to examine the effect of cross-gender endorsement on purchase intention.
Findings
The findings from three experiments provide empirical evidence that the endorsement of female-gendered products by male anchors leads to a significant decrease in the evaluation of these products among female consumers. This negative effect is mediated by a sense of gender-identity incongruence experienced by female consumers. Furthermore, the study demonstrates that female customers exhibit higher purchase intent for female-gendered products endorsed by male virtual anchors compared to real anchors; however, the same pattern was not observed in the case of female anchors.
Originality/value
This paper empirically examines the possible negative effects of the male anchor endorsement in the live streaming context. It reveals the underlying mechanism of this negative effect, and how the virtual “presence” take a role in this underlying mechanism.

Abstract
Purpose
An integral component in heat pipes (HPs) and vapor chambers (VCs) is a porous wicking structure. Traditional methods for manufacturing wicking structures within HPs and VCs involve secondary manufacturing processes and are generally limited to simple geometries. This work aims to leverage the unprecedented level of design freedom of laser powder bed fusion (LPBF) additive manufacturing (AM) to produce integrated wicking structures for HPs and VCs.
Design/methodology/approach
Copper wicking structures are fabricated through LPBF via partial sintering and via the formation of square, hexagonal and rectangular arrangements of micro-pins and micro-grooves, produced in multiple build directions. Wicks are characterized by conducting capillary performance analysis through the measurement of porosity, permeability and capillary rate-of-rise.
Findings
Copper wicking structures were successfully fabricated with capillary performance, K/reff, ranging from 0.186–1.74 µm. The rectangular-arrangement micro-pin wick presented the highest performance.
Originality/value
This work represents the first published report on LPBF AM of copper wicking structures for HPs/VCs applications and represents foundational knowledge for fabricating complete assemblies of copper VCs and HPs through LPBF AM.

Abstract
Purpose
Recent years have witnessed an unexpected and astonishing rise of AI-generated (AIGC), thanks to the rapid advancement of technology and the omnipresence of social media. AIGCs created to mislead are more commonly known as DeepFakes, which erode our trust in online information and have already caused real damage. Thus, countermeasures must be developed to limit the negative impacts of AIGC. This position paper aims to provide a conceptual analysis of the impact of DeepFakes considering the production cost and overview counter technologies to fight DeepFakes. We will also discuss future perspectives of AIGC and their counter technology.
Design/methodology/approach
We summarize recent developments in generative AI and AIGC, as well as technical developments to mitigate the harmful impacts of DeepFakes. We also provide an analysis of the cost-effect tradeoff of DeepFakes.
Research limitations/implications
The mitigation of DeepFakes call for multi-disciplinary research across the traditional disciplinary boundaries.
Practical implications
Government and business sectors need to work together to provide sustainable solutions to the DeepFake problem.
Social implications
The research and development in counter-technologies and other mitigation measures of DeepFakes are important components for the health of future information ecosystem and democracy.
Originality/value
Unlike existing reviews in this topic, our position paper focuses on the insights and perspective of this vexing sociotechnical problem of our time, providing a more global picture of the solutions landscape.

Abstract
Stresses issues brought up in the first World Wide Web conference on relationship marketing. Based on research on relationship marketing going back to the early 1970s which resulted in the definition of 30 relationships in marketing ‐ the 30R approach. Brings up inconsistencies in marketing, among them the mix‐up between relationship marketing as a phenomenon and a term; values and ethics; practice versus theory and education; differences between Europe and the USA; and the ghost‐hunt for an unambiguous definition. Concludes that relationship marketing requires a dramatic change in marketing thinking and behaviour; it is a paradigm shift, not an add‐on to traditional marketing management.
