The purpose of this paper is to investigate the distribution characteristics of airflow in mine ventilation suits with different pipeline structures when the human body is bent at various angles. On this basis, the stress points are extracted to investigate the pressure variation of a ventilation suit under different ventilation rates and pipeline structures.

Based on the three-dimensional human body scanner, portable pressure test and other instruments, a human experiment was conducted in an artificial cabin. The study analyzed and compared the distribution characteristics of clearance under three different pipeline structures, as well as the pressure variation of the ventilation suit.

The study found that the clearance in front of two pipeline structures gradually increased in size as the degree of bending increased, and there was minimal clearance in the chest and back. The longitudinal structure exhibits a significant decrease in clearance compared to the spiral structure. The pressure value of the spiral pipeline structure with the same ventilation volume is low, followed by the transverse structure, while the longitudinal structure has the highest pressure value. The increase in clothing pressure value of a spiral pipeline structured ventilation suit with varying ventilation volumes is minimal.

The ventilation suit has a promising future as a type of personal protective equipment for mitigating heat damage in mines. It is of great value to study the pipeline structure of the ventilation suit for human comfort.

This study explores the influence of organizational structure on relationship formation and tacit knowledge sharing within a family business context.

Utilizing a single case study approach, data were collected through interviews and questionnaires from 12 participants at a family-owned advertising and communication firm in Beirut, Lebanon.

The research highlights the critical role of organizational structure in enhancing organizational effectiveness through knowledge transfer. It underscores how both intraorganizational and interorganizational ties influence knowledge sharing processes and demonstrates the varying impacts of tie strength on tacit knowledge distribution.

This paper contributes to the literature by examining the interdependence between organizational structure, tacit knowledge transfer and tie strength in family businesses. By analyzing these elements across internal and external boundaries, the study offers a fresh perspective on network dynamics. The research highlights that traditional definitions of network ties may not fully capture the unique environment of family firms, where structural nuances impact knowledge sharing and performance. Practically, the findings provide actionable insights for managers to design organizational structures that optimize tacit knowledge flow, fostering innovation and competitiveness. This work challenges existing frameworks and offers guidance for improving knowledge management in family businesses, supporting sustainable growth and success.

The purpose of this paper is to study the influence of inflated energy prices on the capital structure of Indian manufacturing corporations and to investigate whether the capital structure of Indian firms is driven by demand shocks or supply shocks during the study period.

Not only this, the study also highlights that factors pertaining to the demand shock had induced Indian corporations to have higher debt levels in the capital structure.

This study has laid some ground work to explore the influence of inflation on capital structure of Indian firms upon which a more detailed evaluation could be based.

To the best of the authors’ knowledge, this study is the first that explores the influence of inflated energy prices on the capital structure of manufacturing firms in India by using the most recent data.

Purpose: The purpose of the chapter is to determine the dependence of the process of decision making in modern business systems on their organizational structure and to substantiate the necessity for considering the requirements to the process of decision making during designing the organizational structure of a business system.

Methodology: A new simplified classification of the organizational structure of business systems according to the criterion of complexity is offered, and its two main types are distinguished – organizational structure of low complexity and organizational structure of high complexity.

Conclusions: According to the offered classification, dependence of the process of decision making in modern business systems on complexity of their business structure at each stage of making of managerial decisions is determined. As a result of analysis of statistical data, it is determined that business systems with organizational structure of low complexity dominate in Russia. By the example of modern Russian business systems with the organizational structure of high complexity – Sberbank, Lukoil, Gazprom, and Rosneft – it is shown that formation of the structure of this type and supporting its functioning requires resources and thus is inaccessible for most modern business systems. Moreover, the expected advantages, related to high probability of making of optimal managerial decisions, are not always gained in practice.

Originality/value: It is substantiated that the process of decision making in modern business systems largely depends on the complexity of their organizational structure. With increase of complexity of a business system, resource intensity of decision making and duration of this process increase, but the risk of nonoptimal decisions decreases. Organizational structure of low complexity is peculiar for business systems that have deficit of financial and human resources, which does not allow using the means of optimization and fully control the process of decision making. However, in this case, managerial decisions are made much quicker. In the conditions of modern market economy, it is necessary to make quick optimal decisions, which cannot be achieved within the organizational structure of either low or high complexity. Thus, it is necessary to find a way to make quick optimal managerial decisions beyond the design of organizational structure.

Variations of human-versus-structure and within-humans at the organizational and the project level are critical in shaping the internal arrangement for effectiveness of project-based organization’s (PBOs) governance. Recent discourse presents governmentality at the organizational level and leadership at the project level as human agency of governance, whereas governance structures to be their counterpart. However, project-level mechanisms of governmentality that can help to understand possible variations among these governance dimensions remained veiled. This study uses institutional theory to explore these internal arrangements accommodated by variations of PBOs governance dimensions at the project level.

The study followed Eisenhardt protocols of multiple case study design using an abductive research approach. Considering the heterogeneity of governance as a phenomenon in literature, boundary conditions were established before theorizing the model of the study to avoid ambiguities and define the research scope. Five PBOs were chosen using theoretical sampling, yielding 70 interviews. Data were analyzed by constant comparison with theory, using replication logic and cross-case analysis.

Findings revealed that project managers perform a buffer function for governmentality at the project level. Identified mechanisms of governmentality at the project level included two downward mechanisms, i.e. communication and informal interactions of governors, and two upward mechanisms of adaptation and reciprocity by project managers and project team members. Cross-analysis for variations among PBOs’ governance at the project level revealed seven arrangements showcasing synergies or contrasts.

The study adds to organizational project management literature by advancing the significance of congruence between humans and structures in project governance. Furthermore, the synchronization of the project manager’s leadership style with the governmentality approach and governance structure of PBOs is of crucial importance at the project level. Findings suggest the same by showcasing synergetic versus contrasting internal arrangements accommodated in varying PBOs governance dimensions. Implications highlight that synergies among PBOs governance dimensions and project manager’s styles can minimize conflicts and inconsistencies in governance implementation, whereas contrasts might trigger them.

This research examines the long-held belief in the adaption-related literature that a firm’s ability to adapt organizational structure to changing environments is related to superior performance. We create and test a construct that reflects an organization’s ability to change structure, which we call Supply Chain Structural Adaptability (SCSA), rather than relying on proxies (e.g. structural form or organizational modularity) used in prior studies.

Quantitative data was collected from 218 firms to test our conceptual model.

We find that SCSA has a mixed effect on profitable growth under various environmental conditions.

We find evidence that refutes two widely held assumptions in organization research, namely, that structural form serves as a reasonable proxy for structural adaptability and that the benefits of adaptive capabilities always increase as environmental dynamism increases.

Hospital governance accountability structures in Iran, similar to other countries, have undergone various reforms with different goals. The current study aimed to identify the rules and regulations of the hospital governance structure in Iran and how they pay attention to accountability.

This qualitative document content analysis study was conducted using hospital governance structure documents in Iran using the Ready materials, Extract data, Analyze data and Distil (READ) document analysis framework. 2,921 documents were extracted from the official government websites of Iran. After screening, seven documents related to the hospital governance structure were selected. A directed content analysis approach was used. The findings were finally future purification matched with the original documents.

The findings showed that documents had not addressed the inclusive governance structure of the hospital comprehensively. The medical staff organization structure is not considered in the documents, and its duties are assigned to a technical or a clinical director. Most documents addressed financial accountability. The documents did not require the hospital’s governance to have an inclusive accountability structure. However, they paid more attention to the administrative and financial autonomy of hospitals.

Accountability is one of the most essential components in the hospital's governance structure. It can increase the success of hospital efficiency, effectiveness, vision and mission fulfillment. The study result can help health services policymakers and managers formulate better organization structure rules and regulations for hospital governance accountability.

This study is the first qualitative analysis of accountable governance structure documents in Iranian hospitals. We used the READ method as a comprehensive approach for document analysis.

This study compares the fatigue performance and biocompatibility of as-built and chemically etched Ti-6Al-4V alloys in TPMS-gyroid and stochastic structures fabricated via Powder Bed Fusion Laser Beam (PBF-LB). This study aims to understand how complex lattice structures and post-manufacturing treatment, particularly chemical etching, affect the mechanical properties, surface morphology, fatigue resistance and biocompatibility of these metamaterials for biomedical applications.

Selective Laser Melting (SLM) technology was used to fabricate TPMS-gyroid and Voronoi stochastic designs with three different relative densities (0.2, 0.3 and 0.4) in Ti-6Al-4V ELI alloy. The as-built samples underwent a chemical etching process to enhance surface quality. Mechanical characterization included static compression and dynamic fatigue testing, complemented by scanning electron microscopy (SEM) for surface and failure analysis. The biocompatibility of the samples was assessed through in-vitro cell viability assays using the Alamar Blue assay and cell proliferation studies.

Chemical etching significantly improves the surface morphology, mechanical properties and fatigue resistance of both TPMS-gyroid and stochastic structures. Gyroid structures demonstrated superior mechanical performance and fatigue resistance compared to stochastic structures, with etching providing more pronounced benefits in these aspects. In-vitro biocompatibility tests showed high cytocompatibility for both as-built and etched samples, with etched samples exhibiting notably improved cell viability. The study also highlights the importance of design and post-processing in optimizing the performance of Ti64 components for biomedical applications.

The comparative analysis between as-built and etched conditions, alongside considering different lattice designs, provides valuable information for developing advanced biomedical implants. The demonstration of enhanced fatigue resistance and biocompatibility through etching adds significant value to the field of additive manufacturing, suggesting new avenues for designing and post-processing implantable devices.

This study aims to explore the provision of accounting ethics education in Ethiopian accounting programs through structuration theory.

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.

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.

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.

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.

This paper proposes a framework to identify a pattern in the relationship between firms’ cost structure (i.e. fixed versus variable) and their volatility in stock returns.

Our empirical analysis is based on a panel data regression where we use an extended sample period and a time-series regression-based elasticity measure of operating leverage.

We document significantly higher systematic risk among firms with large fixed costs, a conclusion which confirms theoretical predictions of earlier studies. In new findings, we document high firm-specific risk and high stock return volatility among firms with a fixed cost structure.

The paper fills a gap in the literature by examining the effect of cost structure using various operating leverage measures and other control measures for firm characteristics on idiosyncratic risk. Studies that seek to explain firms’ systematic risks are numerous; conversely, there are relatively fewer studies on the determinants of firms’ specific risks.
