Abstract

Purpose

In fire resistance tests (FRTs) of building materials, a crucial criterion to pass the test procedure is to avoid the leakage of the hot flue gases caused by gaps and cracks occurring due to the thermal exposure. The present study's aim is to calculate the deformation of a steel door, which is embedded within a wall made of bricks, and qualitatively determine the flue gas leakage.

Design/methodology/approach

A computational fluid dynamics/finite element method (CFD/FEM) coupling was introduced representing an intermediate approach between a one-way and a full two-way coupling methodology, leading to a simplified two-way coupling (STWC). In contrast to a full two way-coupling, the heat transfer through the steel door was simulated based on a one-way approach. Subsequently, the predicted temperatures at the door from the one-way simulation were used in the following CFD/FEM simulation, where the fluid flow inside and outside the furnace as well as the deformation of the door were calculated simultaneously.

Findings

The simulation showed large gaps and flue gas leakage above the door lock and at the upper edge of the door, which was in close accordance to the experiment. Furthermore, it was found that STWC predicted similar deformations compared to the one-way coupling.

Originality/value

Since two-way coupling approaches for fluid/structure interaction in fire research are computationally demanding, the number of studies is low. Only a few are dealing with the flue gas exit from rooms due to destruction of solid components. Thus, the present study is the first two-way approach dealing with flue gas leakage due to gap formation.

Abstract

Purpose

As an advanced manufacturing method, additive manufacturing (AM) technology provides new possibilities for efficient production and design of parts. However, with the continuous expansion of the application of AM materials, subtractive processing has become one of the necessary steps to improve the accuracy and performance of parts. In this paper, the processing process of AM materials is discussed in depth, and the surface integrity problem caused by it is discussed.

Design/methodology/approach

Firstly, we listed and analyzed the characterization parameters of metal surface integrity and its influence on the performance of parts and then introduced the application of integrated processing of metal adding and subtracting materials and the influence of different processing forms on the surface integrity of parts. The surface of the trial-cut material is detected and analyzed, and the surface of the integrated processing of adding and subtracting materials is compared with that of the pure processing of reducing materials, so that the corresponding conclusions are obtained.

Findings

In this process, we also found some surface integrity problems, such as knife marks, residual stress and thermal effects. These problems may have a potential negative impact on the performance of the final parts. In processing, we can try to use other integrated processing technologies of adding and subtracting materials, try to combine various integrated processing technologies of adding and subtracting materials, or consider exploring more efficient AM technology to improve processing efficiency. We can also consider adopting production process optimization measures to reduce the processing cost of adding and subtracting materials.

Originality/value

With the gradual improvement of the requirements for the surface quality of parts in the production process and the in-depth implementation of sustainable manufacturing, the demand for integrated processing of metal addition and subtraction materials is likely to continue to grow in the future. By deeply understanding and studying the problems of material reduction and surface integrity of AM materials, we can better meet the challenges in the manufacturing process and improve the quality and performance of parts. This research is very important for promoting the development of manufacturing technology and achieving success in practical application.

Abstract

Purpose

This research aims to examine and understand the rationales and modalities behind the use of disclosure before, during and after a corporate governance scandal involving CPA Australia (CPAA).

Design/methodology/approach

Data beyond CPAA's annual reports were collected, such as news articles, media releases, an independent review panel (IRP) report, and the Chief Operating Officer's letter to members. These disclosures were manually coded and analysed through the word counts and word trees in NVivo. This study also relied on Norbert Elias' conceptual tool of power games among networks of actors – figurations – to model the scandal as a power game between the old Board, the press, concerned members, the IRP and the new Board. This study analysed the data to reveal a collective and in fieri power balance that changed with the phases of the scandal.

Findings

A mix of voluntary, involuntary, requested and absent disclosures was important in triggering, managing and ending the CPAA scandal. Moreover, communication and disclosure fulfilled a constitutive role since both: mobilised actors, enabled coordination among actors, contributed to pursuing shared goals and influenced power balances. Such a constitutive role was at the heart of the ability of coalitions of figurations to challenge and restore the powerful status quo.

Originality/value

This research introduces to accounting studies the collective and in fieri dimensions of power from figurational theory. Moreover, the research sheds new light on using voluntary, involuntary, requested and absent disclosures before, during and after a corporate crisis.

Abstract

Purpose

Technology-enabled business-to-business (B2B) services contribute the largest share to GDP growth and are fundamental for an economy’s value creation. This article aims to identify key service- and digital technology-driven B2B innovation modes and proposes a research agenda for further exploration.

Design/methodology/approach

This conceptual paper adopts a techno-demarcation view on service innovation, encompassing three core dimensions: service offering (the service product, or the “what”), service process (the “how”) and service ecosystem (the “who/for whom”). It delineates the implications of three digital technologies – the internet-of-things (IoT), intelligent automation (IA) and digital platforms – for service innovation across these core dimensions in B2B markets.

Findings

Digital technology has immense potential ramifications for value creation by reshaping all three core dimensions of service innovation. Specifically, IoT can transform physical resources into reconfigurable service products, IA can augment and automate a rapidly expanding array of service processes, while digital platforms provide the technical and organizational infrastructure for the integration of resources and stakeholders within service ecosystems.

Originality/value

This study suggests an agenda with six themes for further research, each linked to one or more of the three service innovation dimensions. They are (1) new recurring revenue models, (2) service innovation in the metaverse, (3) scaling up service innovations, (4) ecosystem innovations, (5) power dependency and lock-in effects and (6) security and responsibility in digital domains.

Abstract

The study discusses the professionalization of academic leadership in Israel by analyzing and comparing two different training programs: the Hebrew University of Jerusalem’s (HUJI) program and the CHE-Rothschild program. The HUJI program began in 2016 to train the professoriate to take charge of leadership positions alongside a separate program for administrative staff, while the CHE-Rothschild program was launched in 2019 to train academic leaders, both professors and administrators from universities and colleges nationwide. The analysis reveals two “ideal types” of collegiality: While Model A (exemplified by the HUJI program) bifurcates between the professoriate and administrative staff, Model B (exemplified by the CHE-Rothschild program) binds administrative and academic staff members through course composition, pedagogy, and content. The study suggests a pattern of redefinition of collegiality in academia: we find that while academic hierarchies are maintained (between academic faculty and administrative staff and between universities and colleges), collegiality in academia is being redefined as extending beyond the boundaries of the professoriate and emphasizing a partnership approach to collegial ties.

Abstract

Purpose

This research seeks to unpack a relevant, hitherto overlooked connection between employees' perception that family incivility is undermining their work and their displays of submissive behavior. The authors predict and test a mediating role of employees' work alienation beliefs and a moderating role of their ego resilience in this connection.

Design/methodology/approach

The research hypotheses were tested with survey data collected in three rounds, separated by three weeks each, among employees who work in the education sector in Pakistan. The statistical analyses relied on the PROCESS macro, which supports the simultaneous estimation of the direct, mediation and moderated mediation effects that underpin the proposed theoretical framework.

Findings

An important reason that victims of disrespectful treatment at home fail to fight for their rights at work is that they develop parallel beliefs of being disconnected from work. This intermediary role of work alienation beliefs is less prominent though when employees can rely on their personal resource of ego resilience.

Practical implications

For human resource (HR) managers, this research offers a critical explanation, related to a sense of being estranged from work, for why family-induced work hardships might cause employees to exhibit subservient behaviors at work. It further reveals how this process can be contained if employees have the capability to adapt flexibly to different situations.

Originality/value

This study contributes to extant research by explicating how and when family-induced work hardships might escalate into work responses that mirror employees' experiences at home.

Abstract

Purpose

The purpose of this article is to investigate the communicative constitution of organizational inclusion and/or exclusion through humorous acts at the expense of members of minorities and/or historically disadvantaged groups.

Design/methodology/approach

Semistructured interviews with 84 employees in Austria and Germany dealing with their experiences regarding diversity and inclusion (D&I) at work were conducted and analyzed in two steps. First, a thematic text analysis was performed to structure the content and identify relevant themes and anecdotes for further analysis. Second, a ventriloquial analysis sought to identify the physically absent yet present voices in these anecdotes.

Findings

The interviews revealed that jokes and quips mostly target colleagues of observable foreign origin. The analysis further identified three themes that show that disparaging humor can simultaneously reinforce inclusion/exclusion across hierarchies and create boundaries within teams – but in different ways. The findings also indicate that above all prejudices “participate” in such events and that in most cases the collective is invoked to increase the joke's “authority”.

Originality/value

This research is the first one that investigates humor in the context of D&I through a communicative constitution of organization (CCO) lens, which facilitates studying the constitutive character of humorous communication in terms of inclusion and exclusion. Moreover, this is one of the first empirical humor studies to draw on established theory-driven concepts of inclusion-exclusion in its analysis.

Abstract

Purpose

Institutional, economic, social and technological advancements enable openness to cope with wicked public management issues. Although open innovation (OI) is becoming a new normality for public sector entities, scholarly knowledge on this topic is not fully systematized. The article fills this gap, providing a thick and integrative account of OI to inspire public management decisions.

Design/methodology/approach

Following the SPAR-4-SLR protocol, a domain-based literature review has been accomplished. Consistently with the study purpose, a hybrid methodology has been designed. Bibliographic coupling permitted us to discover the research streams populating the scientific debate. The core arguments addressed within and across the streams were reported through an interpretive approach.

Findings

Starting from an intellectual core of 94 contributions, 5 research streams were spotted. OI in the public sector unfolds through an evolutionary path. Public sector entities conventionally acted as “senior partners” of privately-owned companies, providing funding (yellow cluster) and data (purple cluster) to nurture OI. An advanced perspective envisages OI as a public management model purposefully enacted by public sector entities to co-create value with relevant stakeholders (red cluster). Fitting architectures (green cluster) and mechanisms (blue cluster) should be arranged to release the potential of OI in the public sector.

Research limitations/implications

The role of public sector entities in enacting OI should be revised embracing a value co-creation perspective. Tailored organizational interventions and management decisions are required to make OI a reliable and dependable public value generation model.

Originality/value

The article originally systematizes the scholarly knowledge about OI, presenting it as a new normality for public value generation.

Abstract

Purpose

Consumers' perceptions of product intelligence affect their willingness to accept smart offerings. This paper explores how people perceive various smart products based on their smartness profiles, composed of five distinct smartness facets. Additionally, the study investigates how these perceptions of product intelligence impact consumers' evaluation of factors that either promote or impede the adoption of smart products. These factors are examined as potential mediators in the adoption process. This paper aims to determine if the value-based adoption model can be applied to a broad range of smart service systems.

Design/methodology/approach

Consumers assessed one of 28 smart products in a scenario-based quantitative study. Multilevel structural equation modeling (SEM) is used to test the conceptual model, taking the nested data structure into account.

Findings

The findings show that product smartness essentially enhances usage intention via adoption drivers (enjoyment and usefulness) and reduces usage intention via adoption barriers (intrusiveness). In particular, the ability to interact in a humanlike manner increases the benefits consumers perceive, which in turn increases consumer acceptance. Only the smartness characteristic of awareness impairs usage intention, mediated by the perceived benefits of enjoyment and usefulness.

Originality/value

In contrast to previous research, which usually focuses on single smart products, this work examines a variety of different products, which allows for better transferability of the results to other smart offerings. Furthermore, prior research has mainly focused on single facets of product smartness or researched smartness on an aggregated level. By considering the consumer perception of each smartness facet, the authors gain deeper insights into the perceptual differences regarding product smartness and how this affects technology adoption via conflicting key acceptance drivers and barriers.
