Abstract

Purpose

During running-in, the change in the honed cylinder liner surface alters the performance and efficiency of the piston ring-pack system. The present paper, thus, aims to investigate the surface topography and wear and friction evolution of a cylinder liner surface during the running-in tests on a reciprocating ring–liner tribometer under a mixed lubrication regime. After an initial period of rapid wear termed “running-in wear”, a relatively long-term steady-state surface topography can emerge. A numerical model is developed to predict the frictional performance of a piston ring-pack system at the initial and steady-state stages.

Design/methodology/approach

The liner surfaces are produced by slide honing (SH) and plateau honing (PH). The bearing area parameter (Rk family), commonly used in the automotive industry, is used to quantitatively characterize the surface topography change during the running-in process. A wear volume-sensitive surface roughness parameter, Rktot, is used to show the wear evolution.

Findings

The experimental results show that a slide-honed surface leads to reduced wear, and it reduces the costly running-in period compared to the plateau-honed surface. The simulation results show that running-in is a beneficial wear process that leads to a reduced friction mean effective pressure at the steady-state.

Originality/value

To simulate the mixed lubrication performance of a ring–liner system with non-Gaussian roughness, a one-dimensional homogenized mixed lubrication model was established. The real surface topography instead of its statistical properties is taken into account.

Abstract

Purpose

The purpose of this research is to develop a generic framework of a digital twin (DT)-based automated construction progress monitoring through reality capture to extended reality (RC-to-XR).

Design/methodology/approach

IDEF0 data modeling method has been designed to establish an integration of reality capturing technologies by using BIM, DTs and XR for automated construction progress monitoring. Structural equation modeling (SEM) method has been used to test the proposed hypotheses and develop the skill model to examine the reliability, validity and contribution of the framework to understand the DRX model's effectiveness if implemented in real practice.

Findings

The research findings validate the positive impact and importance of utilizing technology integration in a logical framework such as DRX, which provides trustable, real-time, transparent and digital construction progress monitoring.

Practical implications

DRX system captures accurate, real-time and comprehensive data at construction stage, analyses data and information precisely and quickly, visualizes information and reports in a real scale environment, facilitates information flows and communication, learns from itself, historical data and accessible online data to predict future actions, provides semantic and digitalize construction information with analytical capabilities and optimizes decision-making process.

Originality/value

The research presents a framework of an automated construction progress monitoring system that integrates BIM, various reality capturing technologies, DT and XR technologies (VR, AR and MR), arraying the steps on how these technologies work collaboratively to create, capture, generate, analyze, manage and visualize construction progress data, information and reports.

Abstract

Purpose

This paper aims to study a scale development and validation process for an integrative marketing–operations alignment (MOA) theory. This theory was derived from several distinct theories that have attempted to explain the interaction between marketing and operations functions of manufacturing organizations. An initial qualitative research and literature review identified five antecedents to the MOA construct (decision coordination, reward system, information exchange, leadership strategy and performance evaluation) as well as two outcomes (customer orientation and competitor orientation).

Design/methodology/approach

The scale was developed and validated using successive testing processes including exploratory factor analysis, confirmatory factor analysis and structural equation modeling (LISREL).

Findings

The outcome of the research is a tested and validated model of MOA. While more work needs to be done to test and potentially extend the theory, this research has produced a basic functional model of the MOA process.

Research limitations/implications

The limitations include target populations, choice of industry and geography and cross-sectional time horizon of the study.

Originality/value

This study represents an original contribution to the organizational theory literature, as it provides both a sound theoretical basis and a validated measurement model for the proposed theory of MOA. While this research does draw on existing models, it is more comprehensive and theory-based than the existing models.

Abstract

Purpose

This paper aims to improve marketing managers’ use of information from sales. The authors propose and empirically test the link between cross-functional trust and marketing’s use of information from sales, and whether this effect is contingent on marketing’s power within the firm.

Design/methodology/approach

Cross-sectional survey data were collected from 338 large-scale Hungarian firms. Structural equation modeling and bootstrap procedures were used to test the hypotheses.

Findings

The effect of cross-functional trust on marketing managers’ use of sales information is fully mediated by sales–marketing integration and marketing’s perception of information quality. However, the power of marketing within the firm moderates this mediating relationship.

Research limitations/implications

This paper provides empirical evidence concerning the mediating mechanisms of transferring cross-functional trust to marketing’s successful use of information from sales. The findings imply that cross-functional trust can improve marketing managers’ use of sales information of firms with powerful marketing units by facilitating integration, whereas it can improve the use of sales information of firms with low marketing power by improving marketing managers’ perception of information quality from sales.

Originality/value

This is the first study that models and empirically investigates marketing managers’ use of information collected by sales. The current study conceptually links and advances extant knowledge on the literatures on the sales–marketing interface and utilization of market information at the individual level and increases the understanding of how cross-functional trust contributes to information use under different contingencies of marketing power.

Abstract

Purpose

The educational environment in Taiwan's primary and secondary schools is becoming increasingly diverse and complex. This study examined the relationship between primary and secondary school principals' working values, organisational climate and organisational adaptation.

Design/methodology/approach

Data were collected from the third Teaching and Learning International Survey (TALIS), which targeted 401 principals in Taiwan's primary and secondary schools, conducted in 2018 by the Organisation for Economic Co-operation and Development (OCED). In this study, a structural equation model was constructed.

Findings

The results indicated that primary and secondary school principals generally had positive work values, and their schools' organisational climate and adaptation were positive. In addition, the work values, organisational climate and organisational adaptation models showed good fit for a variety of potential variables. Furthermore, the organisational climate had a mediating effect that strengthened the principals' work values and was a major factor in enhancing organisational adaptation. The results suggest that in addition to principals' positive work values, fostering a cooperative organisational climate—such as the perceived level of support from supervisors and the environment—is essential to enhance schools' organisational adaptation.

Originality/value

The principal's work value has a profound impact on the creation of a school's organisational atmosphere, the cohesion of members' consensus and the organisation's contingency decision-making in response to the external environment. This study adduces more diverse recommendations for the development of school affairs.

Abstract

Purpose

The past five years have seen a growth in studies of police body-worn cameras (BWCs). A large share of the research focused on individual officer attitudes toward these new law enforcement tools. The scholarship, however, focused almost exclusively on their positive and negative perceptions of body cameras or correlations between those attitudes and general officer characteristics. This study examined whether the influence of negative or “concerning” policing attitudes toward body cameras is mediated by other variables, such as officer outlooks toward law enforcement, officers' perceptions of citizen cooperation or their opinions of the public.

Design/methodology/approach

An online survey was distributed to a convenience sample of police offices from two Northeastern police agencies.

Findings

Findings indicate that the relationship between experience and concerning perceptions of body cameras is mediated by distrust in citizens and perceived civilian cooperation. Further, an office's outlooks regarding aggressive law enforcement tactics do not have a direct effect on concerning perceptions of body cameras, nor do they serve as a mediator between years of experience and concerning perceptions of body cameras.

Originality/value

Findings uncover the nuance and complexity of studying and understanding police officer outlooks and perceptions of BWCs. Future experimental designs should include general outlook measures.

Abstract

Underground parking projects are expensive. The capital cost of underground parking projects has been, and still is, one of the promoter’s main economic concerns. Therefore, the capital cost estimation is an essential task in the early stages of underground parking projects. In this context, the promoters mainly use cost estimation models, most of them produced by methodologies with lack of precision and with low performances. Over the last years Portugal has embarked on a large programme of underground parking projects in the major cities. The present research work is based on data and knowledge colleted from that programme. This paper presents an analysis of the underground parking projects built and underway in Portugal. It discusses the main variables influencing the capital cost of under‐ground parking projects. Finally, it presents a mathematical model for estimating capital cost of this type of project during the planning phase.

Abstract

Purpose

The purpose of this paper is to investigate the practice of stakeholder engagement as a social network dynamics for stakeholder satisfaction and project success in the lifecycle of mega transport infrastructure projects (MTIPs).

Design/methodology/approach

Hypotheses indicating the positive relationships between stakeholders’ effective attributes, stakeholder engagement as social network dynamics and project success through stakeholders’ satisfaction have been developed. Based on a questionnaire survey and semi-structured interviews, responses have been gathered from the representative groups and organizations on their social network dynamics for their satisfaction and project success. A hypothesized structural equation model has been tested using AMOS statistical software package.

Findings

The analysis highlighted the engagement of the stakeholders within the strategic intents of the project with the public needs and expectations. The model depicts the processes of building social network models based on the capturing of the project’s data in relation to the stakeholders’ communication and satisfaction across the key issues for success in the lifecycle of MTIP.

Practical implications

The model is applicable on most MTIP with a diverse stakeholder base and the underlying complexity associated with the community participation and consultation processes. The model will also support wider stakeholder engagement in the planning of MTIP with optimal operationalization and service delivery from a community perspective.

Originality/value

The research involves an approach for rationalizing the stakeholder engagement policies of the MTIPs by providing an empirically grounded model simultaneously linking various aspects of stakeholder effective attributes, stakeholder engagement and their relationships to stakeholder satisfaction and project success in MTIPs.

Abstract

Purpose

Despite considerable investigations of the various outcomes of perceived brand globalness (PBG), the concept itself remains ambiguous, demanding further conceptual refinement. The purpose of this paper is to contribute to global branding literature by suggesting an extended conceptualization of PBG, and empirically testing a corresponding extended model of global brand effects, relative to the conventional operationalization.

Design/methodology/approach

An empirical study (n=907) involving 63 brands across eight different product categories provides new insights into the composition of global brand effects by explicitly discriminating between different facets of consumers’ brand globalness perceptions (i.e. perceived market reach (PMR), perceived standardization (PST) and global consumer culture positioning (GCCP)).

Findings

The results clearly show that effects associated with global brands are not exclusively positive. While PMR and GCCP have positive effects on consumers’ brand evaluations and attitudes, PST has a strong negative effect on the same outcomes. These effects apply to both domestic and foreign global brands and occur irrespective of the perceived level of risk associated with a given product category.

Originality/value

The results provide managers a clearer picture of the up- and downsides of brand globalness perceptions and urge future studies on global brands to incorporate constructs that account for facets beyond a brand’s market reach to capture the phenomenon holistically.

Abstract

Purpose

The study examined the influence of environmental standards set by the SME agro-based processing firms and farmers' environmental empowerment on farmers' adoption of environmentally friendly agricultural practices; and the mediating role of empowerment on the relationship between SME agro-based processing firm environmental standards and farmers' adoption of environmentally friendly agricultural practices.

Design/methodology/approach

Data was collected from purchasing managers of the agro-based processing firms. The SPSS software, SMART PLS and CB-SEM software were used to obtain results on the influence of environmental standards set by the SME agro-based processing firms on adoption of environmentally friendly agricultural practices; the influence of farmers' environmental empowerment on adoption of environmentally friendly agricultural practices and the mediating role of farmers' environmental empowerment on the relationship between SME agro-based processing firm environmental standards and farmers' adoption of environmentally friendly agricultural practices.

Findings

Findings indicated that SME agro-processing environmental standards have an influence on farmers' adoption of environmentally friendly agricultural practices. Empowering farmers in environmental issues influenced their adoption of environmentally friendly agricultural practices. A partial mediation effect was observed on testing the mediating role of farmers' environmental empowerment on the relationship between SME agro-based processing firm environmental standards and farmers' adoption of environmentally friendly practices.

Research limitations/implications

The study mainly focused on the upstream part of agricultural supply chains. The research has implications to decision-makers in government concerned with enhancing environmentally friendly practices among farmers in general.

Originality/value

The influence of SME agro-based processing firm environmental standards on farmers' adoption of environmentally friendly agricultural practices; the influence of farmers' environmental empowerment on farmers' adoption of environmentally friendly practices; and the mediating role of farmers' environmental empowerment on the relationship between SME agro-based processing firm environmental standards and farmers' adoption of environmentally friendly agricultural practices are aspects that have not been given significant attention.
