Abstract
Purpose
The purpose of this paper is twofold: first, to empirically evaluate the key impediments to the competitiveness of the rail sector in Australia; and second, to provide relevant transport management and policy recommendations for enhanced competitiveness.
Design/methodology/approach
This paper has adopted an empirical approach. A survey was developed and distributed among rail stakeholders in Australia. Accordingly, exploratory factor analysis and confirmatory factor analysis were conducted to evaluate the key impeding areas.
Findings
This paper found four areas that are impeding rail development, these being infrastructure management, shortage of freight data and poor information sharing, service delivery and organisational and commercial interactions.
Research limitations/implications
The theoretical approach of this thesis can be applied to any freight market where competition exists between different transport modes. However, the specific strategies provided in this research in terms of transportation management, infrastructure planning and policy were made according to the specific market condition, infrastructure quality and regulation that exist in Australia.
Practical implications
The findings provide important implications for both industry and government in terms of making transport planning and policy decisions, but also useful insights by identifying the weak parts of the rail sector and directions to target them.
Originality/value
The notion of the rail stakeholder does not appear to have been previously defined in the literature. Therefore, this research takes a broader view of rail stakeholders to include various interest groups within the rail sector and its operational environment.

Abstract
Purpose
This paper aims to examine the relationship between supply integration and firm performance by first, investigating the mediating effects of manufacturing flexibility and mass customization; and second, exploring the moderating role of innovation orientation on the link between internal capabilities and performance.
Design/methodology/approach
Resource orchestration and contingency theories are used to address the mediating and moderating effects. A cross-sectional data set on 242 Swedish manufacturers is used to test for the hypotheses using structural equation modeling.
Findings
The findings provide support for the mediating roles of manufacturing flexibility and mass customization in the relationship between supply integration and firm performance. However, the results point to contrasting contingent effects of innovation orientation. While innovation orientation positively moderates the association between mass customization and firm performance, it shows a negative impact on the link between flexibility and performance.
Research limitations/implications
The study contributes to the literature on the integrative activities with upstream supply chain actors. Specifically, the authors highlight how specific capability configurations comprising of supply integration, manufacturing flexibility and mass customization lead to firm performance. Moreover, the authors provide insights on the contingency role of innovation, especially if firms consider flexibility or customization capabilities.
Originality/value
While the individual impacts of flexibility and customization on performance have been addressed previously, there is a paucity of research on how these two capabilities are integrated with supply integration. Moreover, there is little known regarding the role of innovation orientation on these integrated relationships.

Abstract
Purpose
To examine the interplay between sustainable supply chain management (SSCM) and circular economy, this research conceptualises and empirically tests an integrative framework of environmental information exchange with suppliers (ES), environmental product design (EPD) and cost performance (CP) with the contingency effect of digital orientation (DO). The associations proposed in the integrative framework provide a configuration of SSCM practices that support circular economy's restorative processes in the digital age.
Design/methodology/approach
The resource orchestration theory and contingency theory are used to investigate the mediation and moderating effects, which were tested by a moderated mediation analysis of survey data of 100 firms in Australia.
Findings
The results show that EPD fully mediates the relationship between ES and CP. Further, DO was found to moderate the relationship between EPD and CP, but not the relationship between ES and EPD.
Practical implications
The empirical findings of this study offer an effective SSCM practice configuration for firms seeking to target advanced circular business models and economic benefits. Managers should be aware that ES may not be enough to improve CP; EPD is a required mechanism to translate the ES benefits into cost superiority. Managers should also stimulate a DO culture to develop effective EPD capabilities, which leads to improved CP and a foundation for companies seeking to target circularity.
Originality/value
This study advances prior theoretical and practical knowledge. The authors propose and empirically test an integrated SSCM and circular economy model that incorporates mediation and moderation effects to clarify inconsistent findings in prior work, which provides a more holistic and practical understanding of SSCM practices in the digital context. Furthermore, the SSCM literature recommends the adoption of circular economy principles. The integrated model in this study provides a bridge between SSCM and circular economy.

Abstract
Purpose
Our study advances theory in supply chain resilience (SCRes) by identifying and describing the mechanisms through which interorganizational relationships (IORs) contribute to SCRes.
Design/methodology/approach
We employ a multi-method conceptual development design combining structured and narrative review of the literature, supported by illustrative case studies. A four-stage refinement process was used for data reduction, and analysis was informed by complex adaptive systems (CAS) theory.
Findings
Our findings identify connectivity, collectivity and scalability as key mechanisms through which relationships between organizations contribute to SCRes. These mechanisms draw on IOR elements of information sharing, decision synchronization and incentive alignment to augment self-organization and emergence, and adaptation and coevolution via modifying/advancing resilience strategies and practices.
Originality/value
Our study advances theory and practice of SCRes by expounding on how connectivity, collectivity and scalability act as mechanisms that drive and diffuse the contribution of resilient strategies/practices to resilience capability. This is significant for strategic alignment between IORs and SCRes.

– The purpose of this paper is to identify current impediments to the competitiveness of the rail industry in the Australian non-bulk freight market.
Abstract
Purpose
The purpose of this paper is to identify current impediments to the competitiveness of the rail industry in the Australian non-bulk freight market.
Design/methodology/approach
A systematic literature review was adapted to identify the impediments and challenge themes from 1,081 studies available on the Australian rail industry. To select the studies relevant to the research question, a tollgate criterion was then deployed. Impediments were identified by a structured data synthesis process and a heuristic algorithm was developed to explore the possible relationships between the impediments and challenges.
Findings
Four major themes are apparent, each of which presents the rail industry with challenges in the non-bulk freight market. “Infrastructural inefficiencies and the need for further integration” was ranked as the main rail industry challenge, while “environmental concerns and the associated costs of externalities” was the least. In addition, across the four themes data synthesis identified 43 impediments from purely policy related to technical and operational aspects.
Research limitations/implications
The major implication of this review is the identification of impediments that have no linkage to the four industry challenges as revealed by stakeholders in the literature. That means that the rail industry has been dealing with a number of issues that have not been explored and studied in depth either by practitioners or academics. The underlying elements of impediments in this group are perceived as managerial, organisational and leadership factors. The rail industry has failed to manage its organisational ties across the system, both horizontally and vertically. This issue has been intensified as the result of complex interactions between different transport modes and operators associated with the non-bulk freight sector.
Originality/value
For the first time in the Australian context, this study provides an en masse and summarised picture of impediments to the competitiveness of the rail industry in the non-bulk freight market by systematically reviewing the reports generated by different stakeholders in the last ten years. The outcomes will assist the rail industry and government to understand impediments impacting on the quality of rail freight services that may lead to collaboration on decision-making and investment strategies.

Abstract
Purpose
As hospitals are the most costly service providers in every healthcare systems, special attention should be given to their performance in terms of resource allocation and consumption. The purpose of this paper is to evaluate technical, allocative and economic efficiency in intensive care units (ICUs) of hospitals affiliated by Yazd University of Medical Sciences (YUMS) in 2015.
Design/methodology/approach
This was a descriptive, analytical study conducted in ICUs of seven training hospitals affiliated by YUMS using data envelopment analysis (DEA) in 2015. The number of physicians, nurses, active beds and equipment were regarded as input variables and bed occupancy rate, the number of discharged patients, economic information such as bed price and physicians’ fees were mentioned as output variables of the study. Available data from study variables were retrospectively gathered and analyzed through the Deap 2.1 software using the variable returns to scale methodology.
Findings
The study findings revealed the average scores of allocative, economic, technical, managerial and scale efficiency to be relatively 0.956, 0.866, 0.883, 0.89 and 0.913. Regarding to latter three types of efficiency, five hospitals had desirable performance.
Practical implications
Given that additional costs due to an extra number of manpower or unnecessary capital resources impose economic pressure on hospitals also the fact that reduction of surplus production plays a major role in reducing such expenditures in hospitals, it is suggested that departments with low efficiency reduce their input surpluses to achieve the optimal level of performance.
Originality/value
The authors applied a DEA approach to measure allocative, economic, technical, managerial and scale efficiency of under-study hospitals. This is a helpful linear programming method which acts as a powerful and understandable approach for comparative performance assessment in healthcare settings and a guidance for healthcare managers to improve their departments’ performance.

Abstract
Purpose
The purpose of this paper is to find excellent banks on the basis of identified variables. First of all, banks are evaluated based on operation costs, deposits, staff, investments, net profit, and loans variables. Subsequently, these variables are categorized into inputs and outputs. The performances of the banks based on these variables are analyzed by data envelopment analysis (DEA) method to find efficiency and inefficiency of decision making units (DMUs).
Design/methodology/approach
This research is aimed to determine the best banks based on predetermined indicators. The indicators are categorized into inputs and outputs. DEA method is used to find efficiency and inefficiency of DMU. However, the aim is to find the efficient banks and to implement the model by using AP Super Efficiency method in order to find the most efficient unit for benchmarking. However, some inputs and outputs have more priority for banks than the others, as a result it will require some changes.
Findings
The results indicate that among 13 banks, including ten public and three private, solely five public banks are efficient. Moreover, DEA is used as a benchmarking tool for inefficient banks to be efficient. Among these banks ten of them are public banks and three are private. Among efficient ones, all are public banks. Moreover, five of public banks and three of private are inefficient.
Originality/value
In some cases, inputs and outputs have more priority for DMs than the others, as a result it will require some changes. Also, if one of the inputs or outputs is larger in number than the others, the DMU becomes efficient, despite its low priority. Thus, for solving this problem, the indicators of this research are ranked by Rembrandt method considering the existing ones to find the best banks (best DMU) based on their performance and the relevant indicators.

Abstract
Purpose
This study aims to explore the provision of accounting ethics education in Ethiopian accounting programs through structuration theory.
Design/methodology/approach
A qualitative case study methodology was used, and data were collected through semistructured interviews with faculty members, practitioners and regulatory bodies. The interview transcripts were analyzed using thematic analysis. Accounting curricula were also analyzed to triangulate and support the findings.
Findings
The study revealed a significant gap in the status of accounting ethics education, primarily attributed to a misunderstanding of its importance. While faculty initiatives and student interest have partially mitigated this gap, systemic challenges such as rigid curricula, a lack of awareness and commitment, resource constraints and limited stakeholders’ support persisted. A combined approach to accounting ethics education is required to foster ethical behavior. Hence, the structuration theory highlighted how meanings, power dynamics and norms and values constrained and enabled the provision of accounting ethics education.
Research limitations/implications
The study emphasized the need for stakeholders to influence policymakers’ perceptions regarding the significance of accounting ethics education. The study also provided empirical support for structuration theory. Future research should involve cross-cultural comparisons and explore the ethical behavior of accounting professionals using diverse research designs to highlight the gaps and inform effective educational interventions.
Originality/value
This study contributes to the theoretical application of structuration theory in accounting ethics education. It underscores the critical role of comprehensive curricular reforms, stakeholder engagement and resource allocation.

Abstract
Purpose
The COVID-19 outbreak reached a critical stage when it became imperative for public health systems to act decisively and design potential behavioral operational strategies aimed at containing the pandemic. Isolation through social distancing played a key role in achieving this objective. This research study examines the factors affecting the intention of individuals toward social distancing in India.
Design/methodology/approach
A correlation study was conducted on residents from across Indian states (N = 499). Online questionnaires were floated, consisting of health belief model and theory of planned behavior model, with respect to social distancing behavior initially. Finally, structural equation modeling was used to test the hypotheses.
Findings
The results show that perceived susceptibility (PS), facilitating conditions (FC) and subjective norms are the major predictors of attitude toward social distancing, with the effect size of 0.277, 0.132 and 0.551, respectively. The result also confirms that the attitude toward social distancing, perceived usefulness of social distancing and subjective norms significantly predict the Intention of individuals to use social distancing with the effect size of 0.355, 0.197 and 0.385, respectively. The nonsignificant association of PS with social distancing intention (IN) (H1b) is rendering the fact that attitude (AT) mediates the relationship between PS and IN; similarly, the nonsignificant association of FC with IN (H5) renders the fact that AT mediates the relationship between FC and IN.
Practical implications
The results of the study are helpful to policymakers to handle operations management of nudges like social distancing.
Originality/value
The research is one of its kind that explores the behavioral aspects of handling social nudges through FC.
