Abstract
Purpose
The use of building information modelling (BIM) methodology has been increasing in the architecture, engineering, construction and operation sector, driven to a new paradigm of work with the use of three-dimensional (3D) parametric models. However, building information modelling (BIM) has been mostly used for as-built models of a building, not yet been widely used by designers during project and construction phases for occupational risks prevention and safety planning. This paper aims to show the capacity of developing tools that allow adding functionalities to Revit software to improve safety procedures and reduce the time spent on modelling them during the design phase.
Design/methodology/approach
To reach this objective, a structural 3D model of a building is used to validate the developed tools. A plugin prototype based on legal regulations was developed, allowing qualitative safety assessment through the application of job hazard analysis (JHA), SafeObject and checklists. These tools allow the automated detection of falls from height situations and the automated placement of the correspondent safety systems.
Findings
Revit application programming interface allowed the conception and addition of several functionalities that can be used in BIM methodology, and more specifically in the prevention of occupational risks in construction, contributing this paper to the application of a new approach to the prevention through design.
Originality/value
This paper is innovative and important because the developed plugins allowed: automated detection of potential falls from heights in the design stage; automated introduction of safety objects from a BIM Safety Objects Library; and the intercommunication between a BIM model and a safety database, bringing JHA integration directly on the project. The prototype of this work was validated for fall from height hazards but can be extended to other potentials hazards since the initial design stage.

The purpose of this paper is to present a practical proposal for integrating production control (PC) and quality control (QC) at the shop floor level.
Abstract
Purpose
The purpose of this paper is to present a practical proposal for integrating production control (PC) and quality control (QC) at the shop floor level.
Design/methodology/approach
The proposed method is based on three principles which relate PC and QC at the shop floor level. The proposal is applied successfully at the world's largest pencil factory.
Findings
The results show that the proposed method contributes to improve four performance indicators related to PC and QC at the company studied: increase the average throughput in about 28.9 per cent; reduce the average value of work in process (WIP) in about 35.6 per cent, reduce the average lead time by about 45.4 per cent, and reduce the average defect rate by about 71.4 per cent.
Research limitations/implications
The proposal (mainly because of principle III) is developed to be applied in repetitive production (RP) systems, i.e. environments characterized by low production volume and low product variety.
Practical implications
Some practical implications for industrial managers arises from this study: managers must consider the importance of integrated PC and QC functions in order to get better results concerning performance indicators such as throughput, WIP, lead time, and rejection rate; the materials flow simplification is a prerequisite for a lot of improvement initiatives at the shop floor level; the adequate choice of the production control system (PCS) is vital in order to get positive results regarding the performance indicators related to PC; the determination of the production pace (or rate) for a RP system must take account capacity restrictions and the influence of defect rate on production rate.
Originality/value
The paper is original in that it shows that the performance of the shop floor level can be improved by means of integrating PC and QC, by discussing and implementing a method which simplifies the material flow in the shop floor level, chooses the most adequate PCS and shows how the production rate influence on the rejection rate. Therefore, the paper is important for those which practice industrial management, more specifically on PC and QC functions.

Abstract
Purpose
The purpose of this paper is to present a new hybrid approach based on criticality analysis and optimisation to deal with spare parts inventory management in the initial provisioning phase in the mining industry. Spare parts represent a significant part of mining companies' expenditures, so it is important to develop new approaches to reduce the total inventory value of these items.
Design/methodology/approach
This hybrid approach combines qualitative and quantitative methods based on VED (vital, essential and desirable) analysis, analytical hierarchical process (AHP), and e-constraint optimisation method to obtain the spare parts to be stocked. The study was applied to a large mining company. The mineral sector was chosen due to the great importance to the emerging Brazilian economy and the lack of researches in this sector. In addition, the spare parts have a relevant weight on the total inventory cost.
Findings
Present a novel approach combining multi-objective optimisation and multi-criteria evaluation approaches to tackle the inventory decision in spare parts management. This work also defines and classifies relevant criteria for spare parts management in the mineral sector validated by specialists. The proposed approach achieves an average increase of 20.2% in the criticality and 16.6% in the number of items to be stocked compared to the historical data of the surveyed company.
Research limitations/implications
This paper applies the proposed approach to a mining company in Brazil. Future research in other companies or regions should analyse the adequacy of the criticality criteria, hierarchy and weights adopted in this paper.
Practical implications
The proposed approach is useful for mining industries that deal with a large variety of resource constraints as it helps in formulating appropriate spare part strategies to rationalise financial resources at both tactical and strategic levels.
Originality/value
The paper presents a new hybrid method combining the AHP a multi-criteria decision making (MCDM) approach coupled with e-constraint optimisation to deal with spare parts inventory management allowing for a better spare parts inventory analysis in the initial provisioning phase and providing managers with a systematic tool to analyse the trade-off between spare parts criticality and total inventory value.

Abstract
Purpose
This study examines whether Brazilian health insurance companies (HICs) engage in earnings management through discretionary accruals or operational decisions by refraining from reporting a low indicator of sustainability in the market (IDSM).
Design/methodology/approach
The study used the Jones and Modified Jones models to identify earnings management through discretionary accruals and used the model described by Roychowdhury to estimate the abnormal behaviors of operational decisions. Data covering 2012 to 2018 were collected from the ANS website.
Findings
The results show that HICs engaged in earnings management to avoid reporting a low IDSM. The findings should help health insurance clients make decisions regarding the purchase or change of health insurance. The findings should also encourage regulators to improve their evaluation of the economic and financial risks around HICs.
Originality/value
The National Agency of Supplementary Health (ANS) established a qualification program for HICs, monitoring them based on a set of indicators. Managers may have an incentive to use earnings management to obtain indices that meet the requirements of the ANS qualification program in order to avoid showing signs of abnormality.

The purpose of this paper is to identify and discuss human competences required for sustainability management in organisations.
Abstract
Purpose
The purpose of this paper is to identify and discuss human competences required for sustainability management in organisations.
Design/methodology/approach
The research is based on a systematic review of the literature, through qualitative thematic analysis.
Findings
The research covered 15 years of scientific publications and was summarised in 43 articles. It revealed that education, more than management, was the field of knowledge with more references in human competences, through exploratory methodological approaches. The competences found were plenty, but there is still some misunderstanding regarding their conceptual and theoretical bases.
Research limitations/implications
This research provides evidence that the academic knowledge on the subject is still at its initial stage, and it exposes the debility of the management area in addressing the subject.
Practical implications
The authors intend to indicate to managers some fundamentals for the adoption of human competences for sustainability aiming at a more sustainable performance in organisations.
Social implications
The results may instigate studies concerning the fit of sustainability competences developed on higher education institutions and the job market. From it, curricula and pedagogical projects can be proposed and revised with better alignment to the organisational context.
Originality/value
This paper presents a theoretical contribution by building bridges among different perspectives and fields of knowledge on the topic. The paper also offers a managerial contribution by stimulating practical discussions to develop sustainability in organisations through individuals.

Abstract
Purpose
Embeddedness has gained prominence in entrepreneurship studies. However, the notion that the embeddedness metaphor relates to “market” structures prevails in studies in the area. Entrepreneurship scholars still know little about whether entrepreneurs are eventually embedded in other structures whose relationships go beyond the restricted dimension of the interested actor’s assumption. This study aims to propose investigating the social structures in which a specific type of entrepreneurship, the religious one, is embedded.
Design/methodology/approach
The research was qualitative, using interviews as an evidence collection instrument. A total of 17 entrepreneur-pastors responsible for business churches in Brazil and eight parishioners took part in the study.
Findings
Religious entrepreneurs are embedded in market structures, corroborating a perspective that associates embeddedness with the utilitarian notion. At the same time, entrepreneurs are embedded in two other social structures: reciprocity and redistribution.
Practical implications
This article emphasizes the relevance of going beyond the predominant perspective associated with the utilitarian and rationalized understanding of embeddedness in relationship networks.
Originality/value
This study makes essential contributions. Initially, it attests to the utilitarian perspective of Granovetter’s embeddedness while suggesting incorporating two other dimensions into the metaphor. By highlighting this, this article stresses the need to reinterpret the metaphor of embeddedness and how entrepreneurship scholars use it. Further, by emphasizing the need to consider embeddedness in networks beyond its still utilitarian perspective, this paper highlights unexplored opportunities for entrepreneurship scholars.
