Abstract

Purpose

This paper aims to predict the localized corrosion resistance by the application of artificial neural networks. It emphasizes the importance to take into account the relationships between the physical parameters before presenting them to the network.

Design/methodology/approach

The work was conducted in two phases. At the beginning, the authors executed an experimental program to measure pitting corrosion resistance of carbon steel in an aqueous environment. More than 900 electrochemical experiments were conducted in chemical solutions containing different concentrations of pitting agents, corrosion inhibitors and oxidant reagents. The obtained results were collected in a table where for a combination of the experimental parameters corresponds a pitting potential Epit obtained from the corresponding electrochemical experiment. In the second step, the authors used the experimental data to train different artificial neuron networks for predicting pitting potentials.

Findings

In this step, the authors considered the relationships that the chemical parameters are likely to have between them. Two types of relationships were taken into account: chemical equilibria which are controlled by the pH and the synergistic relationships that some corrosion inhibitors may have when they are in the presence of a chemical oxidant.

Originality/value

This comparative study shows that adjusting the input data by considering the physical relationships between them allows a better prediction of the pitting potential. The quality of the prediction, quantified by a regression factor, is qualitatively confirmed by a statistical distribution of the gap between experimental and calculated pitting potentials.

Abstract

Purpose

In the last decade, greater attention has been paid to the role of management accounting and control (MAC) in making professional organizations more horizontal. The authors argue that earlier research has not shown how the interrelatedness between professional identities and MAC influences attempts to make organizations more horizontal. In this paper the authors respond to the call for more research on the relationship between horizontalization and accounting and control. The purpose of this paper is to contribute to the emerging literature on the relationship between accountability arrangements and professional identities.

Design/methodology/approach

Theoretically the authors have an actor-network theory (ANT) approach. Empirically, the authors followed two episodes where actors at top management levels in two Swedish health care organizations introduced horizontalization.

Findings

The two episodes support the view that the role of MAC when making professional organizations more horizontal is limited. Professionals dominate what happens at the operational level and they do not act on MAC rules and performance targets in opposition of their professional identity. However, in alliance with other interessement devices MAC may have a role in creating overflows, that is, pointing out imperfections in the existing frame. The authors noticed no signs that professionals developed hybrid identities as in previous research.

Originality/value

The authors apply ANT to move beyond the commonly used contingency and new institutional sociology perspectives.

Abstract

Purpose

The aim of the present paper is to examine how the introduction of information and communication technologies (ICTs) can have positive implications in a territorial context, where healthcare organizations are characterized by limited organizational independence and lack of individual statutory autonomy, with limited level of integration between the involved parties (healthcare operators, managers, and patients) and an uneven management of data and of information‐sharing.

Design/methodology/approach

The approach taken was an investigation based on a combination of quantitative and qualitative methods for information‐gathering and data‐analysis in the context of diabetes care. A case study approach was adopted with the aim of enhancing general practitioners' (GPs') performance levels through an evaluation monitoring and by controlling care paths dynamics.

Findings

The realization of the target care path for chronic–degenerative pathologies in the Local Health Trust “Naples 4” in Campania Region (Italy) led to the identification of a suitable framework that modifies, through the implementation of ICT tools, the communications dynamics and the interaction/integration for those actors involved in a patient's care path.

Originality/value

Healthcare markets are currently experiencing an acceleration of technological developments; the study tries to show how the appropriate adoption of new technologies can lead to improvements for the quality of care, managing at the same time the consequent rising costs in the sector.

Abstract

Purpose

The purpose of this paper is to provide a framework for analyzing stakeholder‐management strategies in supply chain collaboration. The authors aim to show how prior dyadic relations with a stakeholder and perception of situational demands on the relationship determine the choice of aggressive vs cooperative strategies in managing stakeholder relationships.

Design/methodology/approach

To develop a blueprint for predicting collaboration strategies, literature on stakeholder theory, stakeholder management strategies, field theory, and organizational mental models was surveyed. From the literature, 31 predictors of eight stakeholder management strategies were identified. To operationalize the study's constructs, results of a national survey were analyzed to determine the significant predictors of stakeholder management strategies.

Findings

Factor analysis identified two groups of stakeholder strategies: aggressive strategies and cooperative strategies. Aggressive strategies feature some form of forceful attitude or behavior toward stakeholders in an attempt to alter other stakeholders' behavior. Cooperative strategies feature supportive attitudes or behaviors towards its stakeholders. Models were developed for these two types of stakeholder management strategies. When the level of trust among stakeholders is low, a firm that presses to complete the collaboration activity may choose aggressive strategies in dealing with its trading partners. On the other hand, a sense of interdependence, a perception that its trading partners share the urgency to collaborate, plus awareness that the collaboration activity benefits all will lead the organization to adopt cooperative strategies.

Practical implications

By examining the factors contributing to an organization's decision to pursue aggressive (e.g. the radio frequency identification – RFID Mandate), rather than cooperative stakeholder management strategies, this study has important implications to advocates of change (e.g. firms mandating RFID compliance), and firms at the receiving end of aggressive stakeholder strategies.

Originality/value

The findings have important implications for advocates of change (e.g. firms mandating RFID compliance). For trading partners to cooperate, the trading partners must be convinced of the urgency of change, that it is appropriate and right to comply with the call for change, and that they have the ability to do it correctly. To firms at the receiving end of aggressive stakeholder strategies, the approach taken by their trading partners may seem like “bullying tactics” exercised by firms in a position of power. Instead, this research suggests that firms use aggressive stakeholder management strategies because of a heightened sense of urgency, difficulty in conveying legitimacy in carrying out the collaborative undertaking to the trading partners, and lack of faith that all stakeholders will do their share to make the collaborative undertaking work.

Abstract

Purpose

This study aims to empirically validate five propositions about the benefits of three-dimensional (3D) visualizations for the management of subsurface utility projects. Specifically, the authors validate whether benefits from 3D in the literature of building construction project management also apply to subsurface utility projects and map them using a taxonomy of project complexity levels.

Design/methodology/approach

A multiple case study of three utility construction projects was carried out during which the first author was involved in the daily work practices at a utility contractor. 3D visualizations of existing project models were developed, and design and construction meetings were conducted. Practitioners' interactions with and reflections on these 3D visualizations were noted. Observational data from the three project types were matched with the five propositions to determine where benefits of 3D visualizations manifested themselves.

Findings

Practitioners found that 3D visualizations had most merit in crowded urban environments when constructing rigid pipelines. All propositions were validated and evaluated as beneficial in subsurface utility projects of complexity level C3. It is shown that in urban projects with rigid pipelines (project with the highest complexity level), 3D visualization prevents misunderstanding or misinterpretations and increases efficiency of coordination. It is recommended to implement 3D visualization approaches in such complex projects

Originality/value

There is only limited evidence on the value 3D visualizations in managing utility projects. This study contributes rich empirical evidence on this value based on a six-month observation period at a subsurface contractor. Their merit was assessed by associating 3D approaches with project complexity levels, which may help utility contractors in strategically implementing 3D applications.
