Abstract
Purpose
The purpose of this paper is to study the effect of heat treatment (HT) applied to an API X60 steel in corrosion resistance and stress corrosion cracking (SCC) susceptibility through slow strain rate tests (SSRT) in NS4 solution and congenital water (CW) to assess external and internal SCC, respectively.
Design/methodology/approach
API X60 steel was heat treated at a temperature of 1,200°C for 30 min followed by water quenching. Specimens from this steel were machined according to NACE TM 198. SSRT were performed in a constant extension rate tests (CERT) machine at room temperature at a strain rate of 1 × 10–6 s–1. For this purpose, a glass cell was used. Corrosion behavior was evaluated through polarization curves (PCs).
Findings
The SCC index obtained from SSRT indicates that the steel heat treated could be susceptible to SCC in CW and NS4 solution; the mechanism of SCC was hydrogen embrittlement. Thus, CW may promote the SCC phenomenon in pipelines. HT improves the steel corrosion resistance. Higher corrosion rate (CR) was observed when the steel is exposed to CW. The corrosion process in X60 steel shows that the oxidation reaction in the anodic branch corresponds to an activation process, and the cathode branches reveal a diffusion process.
Originality/value
The purpose of the heat treatment applied to X60 steel was to generate a microstructure of acicular ferrite to improve the corrosion resistance and SCC behavior.

The purpose of this paper is to determine how family and business priorities influence organisational decline and turnaround in a family business.
Abstract
Purpose
The purpose of this paper is to determine how family and business priorities influence organisational decline and turnaround in a family business.
Design/methodology/approach
Following critical realism as philosophical orientation, this research is based on an exploratory single case study.
Findings
This research identified specific socioemotional wealth priorities driving this organisation decline and turnaround. The study also determined how the family and business dynamic leads to decisions that first trigger the organisational decline and then explain the successful implementation of turnaround strategies.
Research limitation/implications
Findings of this research provide limited and contingent theoretical generalisation. Accordingly, replication and further quantitative research is required for a better understanding of this phenomenon.
Practical implications
Managers can benefit from this paper by noting which behaviour could lead to organisational decline and which factors could lead to a turnaround. Similarly, managers can learn about the importance of the alignment of socioemotional wealth priorities as a critical response factor to determine whether to follow exit strategies or turnaround (succession) actions.
Originality value
The study contributes to the organisational decline literature and family business literature. It advances the understanding of how family businesses should balance family and business priorities to avoid organisational decline and identify strategies successfully implemented for turning around.

Abstract
Purpose
The purpose of this paper is to study the corrosion rate for X52, X60, X65, X70 and X80 steel immersed in Mexican oilfield produced water. For the electrochemical characterization of the five steels rotating disk electrodes, 20°C, 30°C and 45°C of experimental temperature and 0, 500, 1,000 and 2,000 rpm of rotation speed were taken into account. The temperature dependence was analyzed using Arrhenius law. Thus, Rct values obtained from EIS data in comparison with the corrosion rate obtained from polarization curves data were taken into account. Hydrodynamic effects were analyzed by Rct and corrosion rate data.
Design/methodology/approach
Electrochemical impedance spectroscopy and potentiodynamic polarization techniques were used to assess the electrochemical behavior for five pipe steels steel immersed in a natural solution.
Findings
The resistance and corrosion rate taken from electrochemical tests decreased as temperature and hydrodynamic condition also decreased. In addition, the Arrhenius parameter revealed that the natural solution increased the corrosion rate as the activation energy decreased. Typical branches related to reduction-oxidation reaction (dissolution-activation process or corrosion products dissolution) on steel surface were discussed. Optical images analysis shows that corrosion products for X65 steel exposed to oilfield produced water can be attributed to more susceptibility to corrosion damage for this steel grade (Quej-Ake et al., 2018), which is increased with the temperature and rotation speed of the working electrode.
Originality/value
Corrosion process of the five steels exposed to oilfield produced water could be perceptive when Arrhenius analysis is taken into account. This is because oilfield produced water is the most aggressive condition (brine reservoir and sour water) for internal pipelines walls and storage tanks (brine tanks). Thus, stagnant condition was considered as a more extreme corrosive condition because produced water is stored in atmospheric stationary tanks as well as it is transported under laminar condition in zones where oilfield produced water is maintaining in the bottom of the pipe during the production, transporting and storing of the crude oil. In addition, a brief operational process for Reynolds number and the flowrate of the stock tank barrel per day (Q in STBD) using field and Reynolds number data is discussed.

Abstract
Purpose
The purpose of this paper is to add to the quality management body of knowledge by solidifying the connection between operational and strategic aspects of lean transformation. Previous research has examined these issues in isolation, demonstrating mixed results in financial and operational efficiencies. The authors show that when operational and strategic changes are jointly considered the likelihood of success for lean transformation increases.
Design/methodology/approach
The authors provide a literature review of 109 peer-reviewed papers on lean manufacturing and qualitative analysis of 23 Baldrige award winners (2000-2014) that implemented lean to assess the importance of strategic actions in achieving a sustainable competitive advantage through lean transformation.
Findings
The authors find that lean transformation yields mixed results unless strategic actions are taken by senior management. These strategic actions include but are not limited to knowledge management, human resources, and business growth and can result in performance heterogeneity by improving the output/input ratio of the firm. This performance can then manifest as either doing the same level of business with fewer resources (a profit play) or doing more business with the same resources (a growth play). As specific examples, the authors analyzed Baldrige award winners for evidence of lean strategic action to drive performance gains. The authors suggest further model validation through directed interview and/or survey research.
Originality/value
This paper clarifies the need for jointly implementing lean tools with strategic actions. The findings provide more deliberate strategic actions for organizations wishing to increase the likelihood of success of lean transformation and ultimately improve quality.

The purpose of this study is to understand how neuroscientific tools are used and discussed in ongoing research on strategy in organizations.
Abstract
Purpose
The purpose of this study is to understand how neuroscientific tools are used and discussed in ongoing research on strategy in organizations.
Design/methodology/approach
The authors used a bibliometric study of bibliographic pairing to answer the research question. They collected data from the Web of Science and Scopus databases using the keywords “neuroscience*,” “neurostrategy*” and “neuroscientific*.”
Findings
This study presents a framework that relates fundamental aspects discussed in current research using neuroscientific tools: Neuroscience and its research tools in organizations; emotions and information processing; interdisciplinary application of neuroscientific tools; and moral and ethical influences in the leaders' decision-making process.
Research limitations/implications
The inclusion of neuroscientific tools in Strategic Management research is still under development. There are criticisms and challenges related to the limitations and potential to support future research.
Practical implications
Despite recognizing the potential of neuroscientific tools in the mind and brain relationship, this study suggests that at this stage, because of criticisms and challenges, they should be used as support and in addition to other traditional research techniques to assess constructs and mechanisms related to strategic decisions and choices in organizations.
Social implications
Neuroscientific methods in organizational studies can provide insights into individual reactions to ethical issues and raise challenging normative questions about the nature of moral responsibility, autonomy, intention and free will, offering multiple perspectives in the field of business ethics.
Originality/value
In addition to presenting the potential and challenges of using scientific tools in strategic management studies, this study helps create methodological paths for studies in strategic management.

Abstract
Purpose
Lean healthcare is highlighted in the literature as an approach to quality improvement and operational efficiency. The purpose of this paper is to study how Lean healthcare has been implemented by analyzing empirical outcomes.
Design/methodology/approach
The authors used a literature review as the primary research method, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses process. Peer-reviewed journals were analyzed – searching for Lean healthcare implementation, tools used, wastes addressed, outcomes and sustainability.
Findings
Evidence suggests that Lean can improve healthcare operational effectiveness. However, empirical studies show implementation is still highly localized with small successes. Most transformations are focused on implementing one or two Lean tools that primarily target patient waiting times and there is minimal evidence about sustainability. Establishing clear definitions for healthcare-related Lean terminology may improve practice, especially episodic care and service quality.
Originality/value
This work provides a Lean healthcare case review. The research makes a significant contribution to Lean healthcare by increasing understanding (scale, scope and sustainability). From a theory building perspective, the authors suggest that barriers to adoption include a common healthcare-specific Lean terminology, and a need to expand implementation beyond small successes. This understanding will help identify key areas for further research in Lean healthcare management.

Abstract
Purpose
The purpose of this paper is to perform a literature review of peer-reviewed journal articles investigating the relationship between Lean and Green management in light of developing an integrated management model.
Design/methodology/approach
After an extensive search, 60 articles from 1996 to 2016 were identified as relevant to this study.
Findings
The evidence of successful integration of Lean and Green management has largely been weak. The strongest positive evidence between the two management philosophies has been for Lean implementation pushing Green outcomes through operational waste reduction, thus improving environmental performance. The majority of studies suggest highly optimistic outcomes from integrating Lean and Green, however, an integrated operating model of the firm relating Lean and Green is lacking.
Research limitations/implications
The literature review suggests the necessary elements for proposing an integrated operating model of the firm.
Practical implications
The paper offers interesting implications for managers. While most Lean implementations have resulted in some positive environmental outcomes, both management philosophies tend to be implemented independently. Integrating the implementation of Lean and Green offers the potential for synergistic returns.
Originality/value
The findings are derived from a systematic literature review of articles that have studied the relation between Lean and Green management, resulting in a proposed integrated model of firm performance.

Abstract
Purpose
The aim of this paper was to assess the main and interactive effects of job applicant conscientiousness, and nurturing job demands on ratings of overweight female applicants on job suitability and a hiring recommendation. It also examined relations between rater ethnicity and ratings of the job suitability of normal and overweight applicants.
Design/methodology/approach
The study used a 2×2×2 experimental design and data from 400 individuals (201 Anglos and 199 Hispanics) with hiring experience to test the study's hypotheses. Participants were randomly assigned to conditions, and asked to review a resume and picture of a normal or overweight applicant. Then, they were asked to rate the applicant's job suitability and make a hiring recommendation.
Findings
The results revealed that: overweight female applicants were rated as more suitable for jobs and more likely to be recommended for hire when they had high rather than low conscientiousness; Hispanics were more likely to recommend overweight applicants for hire than Anglos; and there was a three-way interaction among applicant weight, rater ethnicity, and nurturing job demands for the hiring recommendation criterion.
Research limitations/implications
The study was conducted in a simulated hiring context. Thus, research is needed to determine if the results generalize to actual work settings.
Practical implications
The results suggest that organizations should provide decision makers with detailed information about applicants' conscientiousness, and the nurturing demands of jobs. When these types of information are presented, raters are less likely to display weight-based bias.
Originality/value
Previous research on weight-based bias was not based on a theoretical model, but the present study used a theoretical framework to guide the development of hypotheses (Stone and Colella, 1996; Stone et al., 1992). In addition, it is the first study to examine the effects of overweight applicant conscientiousness and stereotype-job fit on ratings of job suitability, and differences between Hispanic and Anglo views of overweight applicants.

Abstract
Purpose
Following the recommendation of the food and agriculture organization of the United Nations in agricultural innovation, for taking advantage of emerging technologies, in benefit of small-farmers, the present study explores one of the most ancient crops in the world that privileging the application of tacit knowledge, to become a succulent plant called agave, into the so-called drink of the gods, the mezcal. For this, the purpose of this study is to discover innovation opportunities and reconfiguring knowledge interaction dynamics of the agricultural artisan production of agave-mezcal from Oaxaca, Mexico, using emerging technologies
Design/methodology/approach
Following a qualitative-quantitative approach, the study was carried out with 44 mezcal producers from Oaxaca, Mexico, through face-to-face session, questionaries’ application and field visits, based on the model of socialization, externalization, combination and internalization (SECI) through Likert-scale questions, combining the non-parametric statistical analysis and digital compass, for the detection of technological opportunities
Findings
Basing on artisanal process, context-knowledge place, technological resources and SECIs model results, the opportunities must go in the route of labour in the logic of digital performance. In this sense, becomes relevant to develop an easy-use mobile application for improving the interaction of mezcaleros with external agents and another’s producers., A second proposal is the creation of mezcal-tech-hub, thinking as collaborative space, for promoting the interaction producer-to-producer and producer-to-external agent.
Originality/value
The value of the present study is the empirical description of knowledge dynamics interaction contained in the agricultural artisan production of agave-mezcal through SECI model; the identification of problems, failure or barriers contained in the knowledge interaction dynamics of the agricultural artisan production agave-mezcal; the proposal of innovation opportunities for reconfiguring the knowledge interaction dynamics of the agricultural artisan production agave-mezcal from a developing economy, using emerging technologies.
