Abstract
Purpose
Effectively solving the large tonnage cable in the construction process due to the tensioning method of the inclined cable often appears in the overall cable force and the design value of the deviation is large, cable internal strand force is not uniform, the main girder stress exceeds the limit of the problem affecting the safety of the structure.
Design/methodology/approach
In this study, the finite element method and theoretical analysis method are utilized to propose a construction control method of tensioning the whole bunch of diagonal cables in two parts according to the deformation coordination relationship between the main girder and the diagonal cables. This methodology was implemented during the actual construction of the PAIRA Bridge in Bangladesh.
Findings
Tests conducted on cable-stayed bridges using this controlled tensioning method demonstrate that the measured cable strength of a single strand exhibits an error of less than 0.15% compared to the design target cable strength. The deviation between the measured and designed cable forces ranges from 0.16% to 0.27%. Furthermore, no tensile stress is observed in both the top plate and bottom plate of the root section of the main girder, indicating a state of full-section compression throughout the entire construction process.
Originality/value
Through the comparison with the test value, it can be proved that the whole bunch of diagonal cable tensioned in two parts of the construction control method proposed in this paper can make the internal strand force more uniform, to meet the precision requirements of the site construction, to protect the safety of the bridge construction process. The method proposed in this paper is highly accurate, easy to calculate, and has a high value of popularization and application.

Abstract
Purpose
Tracing audience preferences via audience analytics software has become a vital strategy for many news organizations to ensure their competitiveness in media markets. Extant research also confirms the growing presence of these tools in digital news work in recent years across many local and international news media. However, little is understood about the analytics-driven tensions emerging among journalists and media managers. This paper aims to address this gap by drawing on the labor process theory, which critically analyzes labor and workplace transformations under capitalism.
Design/methodology/approach
The present study employs an interview-based qualitative methodology to deeply understand the factors at the base of the emerging tensions between news workers and managers brought about by audience metrics tools.
Findings
Results show how some perceptions, activities and contextual triggers related to analytics could make relationships between workers and managers problematic. The pressures felt by some journalists stemmed from the way their media managers introduced, interpreted, communicated and applied analytics in the workplace, which were not tied to the quality and learning goals related to journalists’ aspirations. As our evidence suggests, the analytics-induced tensions among news workers were rather an outcome of managerial deficits than of systematic plans to exploit journalists.
Originality/value
By identifying the nature of fundamental analytics-driven tensions in newsrooms, this paper contributes to our understanding of how media managers can embrace more effective approaches toward audience analytics, workforce and organizational performance.

Abstract
Purpose
The purpose of this study is to answer the following research questions. Does hostility shape the undesirable attitudinal consequences of perceived organizational politics (POP)? If so, does emotional intelligence play a role in this context? To answer these questions, the author relies on the affective events theory to present and empirically investigate a moderated mediation model in which: hostility mediates the relationships between POP and both job tension and turnover intentions; and emotional intelligence moderates these relationships.
Design/methodology/approach
The moderated mediation model was tested among a sample of 408 employees. The data was collected in three waves.
Findings
The results revealed that hostility mediated the relationships between POP and the two undesirable attitudes explored. In addition, one of the emotional abilities included in emotional intelligence, namely, self-emotion appraisal, moderated these relationships.
Practical implications
Interventions designed to increase the emotional intelligence level of employees might reduce the hostility they experience in response to POP, and consequently, its harmful implications.
Originality/value
Among the four emotional abilities included in emotional intelligence, only self-emotional appraisal moderates the relationship between POP and hostility. Such findings imply that in some cases, a thorough understanding about one’s emotions is more effective in regulating the hostility experienced in response to organizational politics than other emotional abilities that seem more relevant in this context.

Abstract
Purpose
Simulations exist for the prediction of the behaviour of building structural systems under fire, including two-way coupled fire-structure interaction. However, these simulations do not include detailed models of the connections, whereas these connections may impact the overall behaviour of the structure. Therefore, this paper proposes a two-scale method to include screw connections.
Design/methodology/approach
The two-scale method consists of (a) a global-scale model that models the overall structural system and (b) a small-scale model to describe a screw connection. Components in the global-scale model are connected by a spring element instead of a modelled screw, and the stiffness of this spring element is predicted by the small-scale model, updated at each load step. For computational efficiency, the small-scale model uses a proprietary technique to model the behaviour of the threads, verified by simulations that model the complete thread geometry, and validated by existing pull-out experiments. For four screw failure modes, load-deformation behaviour and failure predictions of the two-scale method are verified by a detailed system model. Additionally, the two-scale method is validated for a combined load case by existing experiments, and demonstrated for different temperatures. Finally, the two-scale method is illustrated as part of a two-way coupled fire-structure simulation.
Findings
It was shown that proprietary ”threaded connection interaction” can predict thread relevant failure modes, i.e. thread failure, shank tension failure, and pull-out. For bearing, shear, tension, and pull-out failure, load-deformation behaviour and failure predictions of the two-scale method correspond with the detailed system model and Eurocode predictions. Related to combined load cases, for a variety of experiments a good correlation has been found between experimental and simulation results, however, pull-out simulations were shown to be inconsistent.
Research limitations/implications
More research is needed before the two-scale method can be used under all conditions. This relates to the failure criteria for pull-out, combined load cases, and temperature loads.
Originality/value
The two-scale method bridges the existing very detailed small-scale screw models with present global-scale structural models, that in the best case only use springs. It shows to be insightful, for it contains a functional separation of scales, revealing their relationships, and it is computationally efficient as it allows for distributed computing. Furthermore, local small-scale non-convergence (e.g. a screw failing) can be handled without convergence problems in the global-scale structural model.

Abstract
Purpose
The organizational environment can influence how employees experience meaningfulness. This study examines the mediating role of meaningful work between organizational ethical climates and the affective well-being of employees. We also test for the moderating role of self-regulatory traits in this relationship.
Design/methodology/approach
Partial least squares – structural equation modelling (PLS-SEM) was employed to test the hypothesized model using responses from 430 working professionals. Recommended robustness checks were conducted before model assessment and hypotheses testing.
Findings
The findings suggest that a caring ethical climate is positively related to affective well-being. Meaningful work dimensions, i.e. unity with others, inspiration and balancing tensions partially mediate the relationship between the caring climate and affective well-being. Integrity with self and balancing tensions fully mediate the negative effect of an instrumental climate on affective well-being. Positive mediation of unity with others and negative mediation of reality were observed between a law and code climate and affective well-being. Moderating effects of self- and other-orientation and self-monitoring were also observed.
Research limitations/implications
The study presents significant insights, however, a few limitations must be discussed. The study has relied on cross-sectional data which may be addressed in future studies.
Practical implications
In times when organizations are spending in large amounts in ensuring meaningful work and employee well-being, this study suggests internal mechanisms that can bring positive impact in employees' work life. Leaders should assess how employees perceive the ethical climate of the organization in order to provide better meaningful work opportunities to the workforce.
Social implications
Having meaningful work and experiencing affective well-being are significant for a collective betterment of society. Meaningful work encourages individuals in identifying how their work if affecting the society. A affectively happy workforce is essential in building a mentally healthy society.
Originality/value
This study contributes to the investigation of organizational factors that help employees find meaning in their work. Based on ethical climate theory, this study highlights how organizations can redesign and modify their ethical climates to provide opportunities for employees to experience meaningful work and improve their affective well-being.

Abstract
Purpose
This paper aims to critically examine the accounting and information systems literature to understand the changes that are occurring in the management accounting profession. The changes the authors are interested in are linked to technology-driven innovations in managerial decision-making and in organizational structures. In addition, the paper highlights research gaps and opportunities for future research.
Design/methodology/approach
The authors adopted a grounded theory literature review method (Wolfswinkel et al., 2013) to achieve the study’s aims.
Findings
The authors identified four research themes that describe the changes in the management accounting profession due to technology-driven innovations: structured vs unstructured data, human vs algorithm-driven decision-making, delineated vs blurred functional boundaries and hierarchical vs platform-based organizations. The authors also identified tensions mentioned in the literature for each research theme.
Originality/value
Previous studies display a rather narrow focus on the role of digital technologies in accounting work and new competences that management accountants require in the digital era. By contrast, the authors focus on the broader technology-driven shifts in organizational processes and structures, which vastly change how accounting information is collected, processed and analyzed internally to support managerial decision-making. Hence, the paper focuses on how management accountants can adapt and evolve as their organizations transition toward a digital environment.

Abstract
Purpose
As part of a national plan to govern professional and organizational development in Norwegian specialist healthcare, the country’s hospital clinics are tasked with constructing development plans. Using the development plan as a case, the paper analyzes how managers navigate and legitimize the planning process among central actors and deals with the contingency of decisions in such strategy work.
Design/methodology/approach
This study applies a qualitative research design using a case study method. The material consists of public documents, observations and single interviews, covering the process of constructing a development plan at the clinical level.
Findings
The findings suggest that the development plan was shaped through a multilevel translation process consisting of different contending rationalities. At the clinical level, the management had difficulties in legitimizing the process. The underlying tension between top-down and bottom-up steering challenged involvement and made it difficult to manage the contingency of decisions.
Practical implications
The findings are relevant to public sector managers working on strategy documents and policymakers identifying challenges that might hinder the fulfillment of political intentions.
Originality/value
This paper draws on a case from Norway; however, the findings are of general interest. The study contributes to the academic discussion on how to consider both the health authorities’ perspective and the organizational perspective to understand the manager’s role in handling the contingency of decisions and managing paradoxes in the decision-making process.

Abstract
Purpose
This study problematizes the prevailing normative and managerial-dominated view of self-initiated employee ambassadorship on social media from a power perspective. The aim is to provide a more nuanced and critical understanding of the negative aspects of this phenomenon.
Design/methodology/approach
The empirical material encompasses qualitative interviews with employees from 14 organizations and Foucault’s concept of disciplinary discursive power to analyze which and how discourses exert power over employee communication on social media and what role visibility plays in it.
Findings
This study indicates that employee ambassadors’ social media communication is governed by two discourses that create complex tensions, where ambassadors constantly must negotiate between self-branding requirements and an authenticity paradox. These tensions intensify through visibility on social media, where employees strategize and situationally silence their communication through self-monitoring and self-surveillance practices. Conclusively, the findings also outline the need for further critical research to offer a deeper understanding of power relations that influence the communication practices of organizational members.
Research limitations/implications
The paper contributes to a more nuanced understanding of self-initiated employee ambassadorship on social media and highlights disciplinary power relations that go beyond organizational borders.
Practical implications
The findings underscore that organizations need to address the critical aspects of self-initiated employee ambassadorship and act as facilitators to support employees in their navigation process.
Originality/value
This paper contributes a new critical power perspective on employee ambassadorship on social media.
