Abstract

Purpose

This study aims to explore how and why employees perceive technology-mediated interruptions differently and the role of sociocultural factors in this process using sociomaterial analysis.

Design/methodology/approach

Data were gathered from 34 Sri Lankan knowledge workers using a series of workshop-based activities. The concept of sociomateriality is employed to understand how sociocultural elements are entangled with technology in work-life boundary experiences.

Findings

The findings of the thematic analyses suggest how culture is intertwined in the way employees perceive technology-mediated interruptions and how they manage information communication technologies (ICTs) to balance their work and nonwork demands. Participants have been unable to avoid technology-mediated boundary interruptions from work, as organisations have created norms to keep employees connected to organisations using information communication technologies. Traditional gender roles are specifically found to be entangled in employees' boundary management practices, disadvantaging women more.

Practical implications

The findings highlight how national culture and gender norms create challenging work-life experiences for female employees than males. This could create a disadvantageous position for female employees in their career progression. It is crucial to consider factors such as boundary preferences and family concerns when deciding on family-friendly work policies. Also, organisations have to consider the development of explicit guidelines on after-hours communication expectations.

Originality/value

Using the lens of sociomateriality, researchers can understand the contextual entanglement of ICTs with national culture and gender norms in creating different work-life boundary experiences. It seems ICTs are creating a disadvantage for female employees when managing work–nonwork boundaries, especially in power distant and collectivist cultures where traditional gender norms are highly valued and largely upheld. This study also contributes to the current discourse on work-life boundaries by providing insights from non-western perspectives.

Abstract

Purpose

The vibration of the rails is a significant source of railway rolling noise, often forming the dominant component of noise in the important frequency region between 400 and 2000 Hz. The purpose of the paper is to investigate the influence of the ground profile and the presence of the train body on the sound radiation from the rail.

Design/methodology/approach

Two-dimensional boundary element calculations are used, in which the rail vibration is the source. The ground profile and various different shapes of train body are introduced in the model, and results are observed in terms of sound power and sound pressure. Comparisons are also made with vibro-acoustic measurements performed with and without a train present.

Findings

The sound radiated by the rail in the absence of the train body is strongly attenuated by shielding due to the ballast shoulder. When the train body is present, the sound from the vertical rail motion is reflected back down toward the track where it is partly absorbed by the ballast. Nevertheless, the sound pressure at the trackside is increased by typically 0–5 dB. For the lateral vibration of the rail, the effects are much smaller. Once the sound power is known, the sound pressure with the train present can be approximated reasonably well with simple line source directivities.

Originality/value

Numerical models used to predict the sound radiation from railway rails have generally neglected the influence of the ground profile and reflections from the underside of the train body on the sound power and directivity of the rail. These effects are studied in a systematic way including comparisons with measurements.

Abstract

Purpose

The layer section of laser additive manufacturing (AM) can be rasterized. Subsequently, the rasterized layer section can be converted into sparse matrix. However, large storage space is occupied due to the high manufacturing resolution. In order to reduce the storage space, the purpose of this research is to propose a lossless compression method to compress the sparse matrix.

Design/methodology/approach

A lossless compression method for additive manufacturing is proposed. According to manifold and irregularity feature of the object of laser AM, a lossless compression method called continuous rows compressed storage (CRCS) based on continuous rows is innovatively proposed. In particular, the better direction strategy of compression method is selected based on the side-projected area per layer.

Findings

Take human teeth as an example, compared with compressed sparse row (CSR), the CRCS has advantage up to 98.88% in storage space. Compared with block compressed sparse row (BCSR), the CRCS has advantage up to 60.04% in storage space.

Originality/value

The proposed CRCS could be employed to compress the sparse matrixes of rasterized layer sections of laser AM. Compared with common lossless compression method of sparse matrix, the compression ratio of CRCS is greater. CRCS is propitious to reduce the storage space usage, thereby improving transmission efficiency.

This method will become a new development trend in subgrade structure design for high speed railways.

Abstract

Purpose

This method will become a new development trend in subgrade structure design for high speed railways.

Design/methodology/approach

This paper summarizes the structural types and design methods of subgrade bed for high speed railways in China, Japan, France, Germany, the United States and other countries based on the study and analysis of existing literature and combined with the research results and practices of high speed railway subgrade engineering at home and abroad.

Findings

It is found that in foreign countries, the layered reinforced structure is generally adopted for the subgrade bed of high speed railways, and the unified double-layer or multi-layer structure is adopted for the surface layer of subgrade bed, while the simple structure is adopted in China; in foreign countries, different inspection parameters are adopted to evaluate the compaction state of fillers according to their respective understanding and practice, while in China, compaction coefficient, subsoil coefficient and dynamic deformation modulus are adopted for such evaluation; in foreign countries, the subgrade top deformation control method, the subgrade bottom deformation control method, the subsurface fill strength control method are mainly adopted in subgrade bed structure design of high speed railways, while in China, dynamic deformation control of subgrade surface and dynamic strain control of subgrade bed bottom layer is adopted in the design. However, the cumulative deformation of subgrade caused by train cyclic vibration load is not considered in the existing design methods.

Originality/value

This paper introduces a new subgrade structure design method based on whole-process dynamics analysis that meets subgrade functional requirements and is established on the basis of the existing research at home and abroad on prediction methods for cumulative deformation of subgrade soil.

Abstract

Purpose

The paper aims to analyse the construct of business model innovation (BMI) in the digital and sustainable landscape, investigating the key role of boundary strategies. The paper advances a comprehensive framework aimed at further understanding the overlap among digitalization, sustainability and BMI development, by a “boundary approach”.

Design/methodology/approach

The paper follows a theoretical approach based on an in-depth review of relevant literature on BMI, digitalization and sustainability as relevant megatrends and, boundary management. By critically integrating the literature, a framework is developed with the objective of supporting firms in the current transformation challenges.

Findings

The paper highlights the interplay among BMIs, megatrends and boundary management. The pressures and opportunities driven by the technological changes have made even more relevant the management of resources placed in the boundary area. Our study shows how firms can rethink their BMs in the digital and sustainable landscape by providing a boundary-based framework.

Practical implications

The framework offers insights and guidelines to help practitioners manage the change processes dictated by digitalization and sustainability. The authors encourage a focus on boundary resources/capabilities to increase the effective management of the digitalization and sustainability processes, to grasp the external stimuli driven by these two megatrends and to develop new/renewed BMIs.

Originality/value

This study emphasizes the importance of developing new BMIs in the current digital and sustainable landscape starting from the analysis of firm’s boundaries. The paper enriches the BMI literature supporting the enhancement of boundary management, leading firms to overcome challenges in the digital and sustainable landscape.

Abstract

Purpose

This paper aims to explore controls within an inter-organisational relationship involving outsourced management accounting services from the contractor’s perspective.

Design/methodology/approach

Qualitative data from within the relationship are analysed in a legitimacy-theory framework, illustrating how controls within the relationship are intended to build the contractor’s legitimacy and what kinds of implications the controls have in relation to conflicts between interests inherent in the relationship.

Findings

The legitimacy perspective clarifies that while controls are aimed at ensuring efficiency for the client, they may also provide symbolic displays of the appropriateness of the contractor’s actions both at an inter-organisational level for the client and at an individual level for the contractor’s employees. While the contractor intends to build legitimacy with the client by demonstrating utility in the form of efficiency, the process also gives the client influence and allows the disposition in terms of shared values to be demonstrated. However, this process has some negative consequences for the contractor’s employees as it is insufficient for serving the boundary-spanning employees’ interests connected with the nature of their work. Hence, the same controls need to yield benefits and fair outcomes for employees. The controls simultaneously foster interconnections that contribute to permanence and formalise the outsourcing of complex services, thereby rendering such processes comprehensible and transferable to other settings, which can be seen to serve the contractor’s continuity interests.

Originality/value

The paper contributes to academic research by illustrating how controls within inter-organisational relationships not only steer boundary-spanners’ work to conform to a client’s needs but may also help to build legitimacy via symbolic properties in the presence of conflicting interests at both an inter-organisational and individual level. It specifically highlights the important role of boundary-spanners lower in the organisational structure, who both affect and are influenced by the intentions to build legitimacy with the client.

Abstract

Purpose

Nearly 40 years since they first appeared, there is renewed interest in dashboards, engendered by the diffusion of business intelligence (BI) desktop software, such as Power BI, QlikView and Tableau, denoted collectively as “self-service” BI. Using these commodity software tools, the work to construct dashboards apparently becomes easier and more manageable and no longer requires the intervention of specialists. This paper aims to analyse the implementation of this kind of commodity dashboard in a university, exploring its role in performance management processes and investigating whether the dashboard affects the organisation (or not).

Design/methodology/approach

This paper focusses on an action research project developed by the authors, where the objective was to design and implement a dynamic performance measurement tool fitting the needs of department directors. The three authors were all involved in the project, respectively, as project manager, dashboard implementation manager and accounting manager of the studied organisation.

Findings

The results reveal a specific but complex change to the procedures and outcomes in the organisation studied, where the dashboard becomes a boundary infrastructure, thereby reviving technical and organisational problems that had been latent for years.

Originality/value

In this paper, the authors contribute to the debate on the digital age and the role of accounting with their exploration into the “revolution” of self-service BI tools. The democratisation and flexibility of these instruments put into discussion two core and somewhat controversial functions of accounting: data integration and personalised reporting.

Abstract

Purpose

The aim of this paper is to frame the stakeholder-driven system mapping approach in the context of climate change, building on stakeholder knowledge of system boundaries, key elements and interactions within a system and to introduce a decision support tool for managing and visualising this knowledge into insightful system maps with policy implications.

Design/methodology/approach

This methodological framework is based on the concepts of market maps. The process of eliciting and visualising expert knowledge is facilitated by means of a reference implementation in MATLAB, which allows for designing technological innovation systems models in either a structured or a visual format.

Findings

System mapping can contribute to evaluating systems for climate change by capturing knowledge of expert groups with regard to the dynamic interrelations between climate policy strategies and other system components, which may promote or hinder the desired transition to low carbon societies.

Research limitations/implications

This study explores how system mapping addresses gaps in analytical tools and complements the systems of innovation framework. Knowledge elicitation, however, must be facilitated and build upon a structured framework such as technological innovation systems.

Practical implications

This approach can provide policymakers with significant insight into the strengths and weaknesses of current policy frameworks based on tacit knowledge embedded in stakeholders.

Social implications

The developed methodological framework aims to include societal groups in the climate policy-making process by acknowledging stakeholders’ role in developing transition pathways. The system map codifies stakeholder input in a structured and transparent manner.

Originality/value

This is the first study that clearly defines the system mapping approach in the frame of climate policy and introduces the first dedicated software option for researchers and decision makers to use for implementing this methodology.

Abstract

Purpose

Modern intra- and inter-organizational arrangements require firms to cross boundaries, but this process represents a crucial and complex challenge, especially for organizations that face pluralistic tensions. Scholars still lack sufficient knowledge of how boundaries can be crossed and what kind of boundary management is necessary within pluralistic contexts. This paper aims to enrich the understanding of these issues by exploring how strategy maps can be mobilized and used as boundary objects to elicit boundary-spanning practices that foster cross-boundary collaboration in pluralistic organizations.

Design/methodology/approach

This paper employs the case study methodology to capture the dynamics of cross-boundary management elicited by the use of a strategy map within a pluralistic social/healthcare organizational context.

Findings

This study identifies four practices of boundary spanning (i.e. identifying and crossing problem boundaries, orchestrating collective responsibilities, acknowledging a common understanding of convergent values and goals, and evolving into action) in the analysed pluralistic context and investigates the conditions under which cross-boundary interactions can mobilize a shared zone of knowing via strategy maps.

Originality/value

This paper suggests a complex (and not linear) processual model of boundary management in pluralistic contexts in which the use of the strategy map mobilizes a dynamic of centrifugal and centripetal movements which engage plural actors in a shared site of collaborative knowing. The study contributes to a conceptualization of boundary management in pluralistic contexts as a progressive social accomplishment.

Abstract

Purpose

This paper aims to solve inhomogeneous dielectric problems by matching boundary conditions at the interfaces among homogeneous subdomains. The capabilities of Hilbert transform computations are deeply investigated in the case of limited numbers of samples, and a refined model is presented by means of investigating accuracies in a case study with three subdomains.

Design/methodology/approach

The accuracies, refined by Richardson extrapolation to zero error, are compared to finite element (FEM) and finite difference methods. The boundary matching procedures can be easily applied to the results of a previous Schwarz–Christoffel (SC) conformal mapping stage in SC + BC procedures, to cope with field singularities or with open boundary problems.

Findings

The proposed field computations are of general interest both for electrostatic and magnetostatic field analysis and optimization. They can be useful as comparison tools for FEM results or when severe field singularities can impair the accuracies of other methods.

Research limitations/implications

This static field methodology, of course, can be used to analyse transverse electro magnetic (TEM) or quasi-TEM propagation modes. It is possible that, in some case, these may make a contribution to the analysis of axis symmetrical problems.

Originality/value

The most relevant result is the possible introduction of SC + BC computations as a standard tool for solving inhomogeneous dielectric field problems.
