Abstract
Purpose
During a fall, a significant part of the major forces is absorbed by the dorsolumbar column area. When the applied stresses exceed the yield strength of the bone tissue, fractures can occur in the vertebrae. Vertebral fractures constitute one of the leading causes of trauma-related hospitalizations, accounting for 15% of all admissions. Posterior pedicle screw fixation has become a common method for treating burst fractures. However, physicians remain divided on the number of fixed segments that are needed to improve clinical outcomes. The present work aims to understand the biomechanical impact of different fixation methods, improving surgical treatments.
Design/methodology/approach
A finite element model of the dorsolumbar spine (T11–L3) section, including cartilages, discs and ligaments, was created. The dorsolumbar stability was tested by comparing two different surgical orthopedic treatments for a fractured first lumbar vertebra on the L1 vertebra: the posterior short segment fixation with intermediate screws (PSS) and the posterior long segment fixation (PL). Distinct loads were applied to represent daily activities.
Findings
Results show that both procedures provide acceptable segment fixation, with the PL offering less freedom of movement, making it more stable than the PSS. The PL approach can be the best choice for an unstable fracture as it leads to a stiffer spine segment.
Originality/value
This study introduces a novel computational model designed for the biomechanical analysis of dorsolumbar injuries, aiming to identify the optimal treatment approaches within both clinical and surgical contexts.

Abstract
Purpose
In recent years, the emergence of Industry 4.0 technologies as a way of increasing productivity has attracted the attention of the manufacturing industry. This study aims to investigate the relationship between Industry 4.0 technologies and lean tools (LTs) by measuring how the internalisation of LTs influences the adoption of Industry 4.0 technologies and how the synergy between them helps improve productivity in European manufacturing firms.
Design/methodology/approach
Results from 1,298 responses were used to analyse linear regression and study the correlation between the use of LTs and Industry 4.0 technologies.
Findings
Results show that the companies analysed tend to implement more Industry 4.0 technologies when their level of lean internalisation is high.
Originality/value
This study provides useful information for managers of manufacturing firms by showing the correlation between LT internalisation and Industry 4.0 technologies, corroborating that optimal implementation of these technologies is preceded by a high level of LT internalisation. Furthermore, although there are studies showing the relationship between LTs and Industry 4.0 technologies, none consider the intensity of their implementation.

Abstract
Purpose
Despite the general recommendation of using a combination of multiple criteria for research assessment and faculty promotion decisions, the raise of quantitative indicators is generating an emerging trend in Business Schools to use single journal impact factors (IFs) as key (unique) drivers for those relevant school decisions. This paper aims to investigate the effects of using single Web of Science (WoS)-based journal impact metrics when assessing research from two related disciplines: Business and Economics, and its potential impact for the strategic sustainability of a Business School.
Design/methodology/approach
This study collected impact indicators data for Business and Economics journals from the Clarivate Web of Science database. We concentrated on the IF indicators, the Eigenfactor and the article influence score (AIS). This study examined the correlations between these indicators and then ranked disciplines and journals using these different impact metrics.
Findings
Consistent with previous findings, this study finds positive correlations among these metrics. Then this study ranks the disciplines and journals using each impact metric, finding relevant and substantial differences, depending on the metric used. It is found that using AIS instead of the IF raises the relative ranking of Economics, while Business remains basically with the same rank.
Research limitations/implications
This study contributes to the research assessment literature by adding substantial evidence that given the sensitivity of journal rankings to particular indicators, the selection of a single impact metric for assessing research and hiring/promotion and tenure decisions is risky and too simplistic. This research shows that biases may be larger when assessment involves researchers from related disciplines – like Business and Economics – but with different research foundations and traditions.
Practical implications
Consistent with the literature, given the sensibility of journal rankings to particular indicators, the selection of a single impact metric for assessing research, assigning research funds and hiring/promotion and tenure decisions is risky and simplistic. However, this research shows that risks and biases may be larger when assessment involves researchers from related disciplines – like Business and Economics – but with different research foundations and trajectories. The use of multiple criteria is advised for such purposes.
Originality/value
This is an applied work using real data from WoS that addresses a practical case of comparing the use of different journal IFs to rank-related disciplines like Business and Economics, with important implications for faculty tenure and promotion committees and for research funds granting institutions and decision-makers.

Abstract
Purpose
This research aimed to describe the phenomenon of the growth of enterprises in the vision of social entrepreneurs.
Design/methodology/approach
This is a qualitative study developed joining eight social entrepreneurs in four organizations, two cooperatives and two associations. Data were obtained in semi structured interviews. Data were analyzed with interpretativist and the classical content analysis.
Findings
The main findings indicated the growth phenomenon presented in five categories: growth intentions, growth meanings, support of other organizations and participation in networks, strategies and difficulties. The results of the research have shown that the growth for the social entrepreneurs is a collective phenomenon, characterized by search of economic value and empowerment.
Research limitations/implications
The main limitation of the research was study only two types of organizations, one garbage cooperative and two association.
Practical implications
The results can help managers of social incubators and stakeholders because it was evidenced the efforts and difficulties that social entrepreneurs face to survive and to search growth.
Social implications
Our findings may contribute to the formulation of public policies oriented to social entrepreneurs.

Abstract
Purpose
Agile methods are increasingly being applied in the contexts of innovation beyond traditional information technology (IT) and physical product development projects, such as when process improvements are being implemented. Nevertheless, this phenomenon is still recent and little addressed in the literature, with few descriptions of empirical cases. This study aims to address this gap.
Design/methodology/approach
This multiple case study aims to present and discuss the application of Agile practices embedded in large companies’ innovation value chains, focusing on improvements of business processes. The following research question is pursued: How are large companies applying elements of Agile methods to their innovation processes when implementing incremental improvements in their operational processes? Based on the idea that the Agile-Stage-Gate model is an alternative to this challenge, this study investigates the application of this hybrid model in two large Brazilian companies by presenting their idiosyncrasies, lessons learned, adaptations, challenges and benefits.
Findings
Overall, it was observed that the experience with the application of the Agile-Stage-Gate model is positive for these companies, with better customer engagement, easier project control and increased productivity of the project team.
Originality/value
For those aiming to implement the Agile-Stage-Gate model, this paper identifies the main adaptations made in order to combine the purist approaches and critical success factors for its implementation.

Abstract
Purpose
Knowledge-intensive entrepreneurial firms (KIE) strongly rely on scientific and strategic research and development (R&D) capabilities to achieve higher performance levels. Hence, the purpose of this paper is to disentangle the effects of scientific capabilities and strategic R&D on KIE performance; and how the constituent elements of these dimensions can be configured to generate conditions for high performance.
Design/methodology/approach
The authors’ empirical setting involves companies that submitted projects to the Innovative Research in Small Businesses (PIPE) program in Brazil. The authors then run partial least square structural equation modeling to verify how scientific and strategic R&D capabilities influence the performance construct. Second, the authors apply fuzzy-set qualitative comparative analysis to identify configurations that are equifinal in terms of generating superior performance.
Findings
Findings indicate a strong association between scientific capabilities and KIE performance. The configurational approach outlines the existence of multiple paths to success, but human capital stands as a core condition throughout estimations.
Practical implications
The authors’ assessment has implications for how KIE firms are managed according to their organizational profiles and trajectories. Also, it advances the authors’ comprehension on how entrepreneurship policies can better target these distinct profiles.
Originality/value
The authors’ analysis provides new evidence on the inherent complexity behind the generation of high performance in KIE when addressing their portfolios of knowledge-related capabilities. More than that, the authors were able to identify the existence of heterogeneous profiles that can equally lead to higher levels of performance.

Abstract
Purpose
Lean management is a suitable methodology for companies that want to improve their productive performance and competitiveness. This study aims to research levels of implementation and internalisation of Lean production tools in Spanish manufacturing companies, and explores differences in behaviour between SMEs and large companies based on data gathered over three time periods. The correlation between Lean adoption and company performance is also analysed.
Design/methodology/approach
Company survey data for the years 2012, 2015 and 2018 collected from 354 respondents were used to conduct a longitudinal study on the level of lean tool adoption and internalisation in manufacturing companies.
Findings
Over the years, the use of Lean tools has increased, whereas levels of internalisation have remained stable. Lean tool use in SMEs and large companies show significant differences in 2012 and 2015, but this is no longer the case 2018. Results also show that higher Lean tool use helps increase return on sales (ROS), and higher levels of internalisation of tools helps reduce the number of products rejected.
Originality/value
To date, there are no known studies on the use and internalisation of Lean tools or their correlations with business performance indicators in Spanish manufacturing companies.

Abstract
Purpose
The purpose of this paper is to identify the characteristics of Brazilian personality, associating them with the cordial man of the book Raízes do Brasil (Roots of Brazil). In addition, it aims to present an agenda for future management studies, suggesting works in several managerial areas which may be influenced by traits of the Brazilian personality.
Design/methodology/approach
A systematic review of studies on Brazil’s image was developed, so that it was possible to identify the main characteristics of the Brazilian personality. The main personality traits found were compared to those identified in the cordial man, from the book Raízes do Brasil.
Findings
The results indicate the main traits of Brazilians’ personality: sensual, cunning, cheerful, creative, hospitable, friendly and cordial. These traits are directly related to cordiality, mentioned in some studies, and also indirectly through words alluding to the character of the cordial man. These traits are related to the Brazilians image abroad and have created a confused image of Brazil.
Research limitations/implications
Regarding the theoretical contribution, the future studies agenda presented suggests the development of papers that relate Brazilians’ personality traits to other areas besides tourism, such as negotiation, organizational culture, exports, foreign direct investment, talent attraction and public diplomacy.
Practical implications
This study indicated that in practice, the Brazilian Government should develop marketing actions to promote a more consistent image of Brazil, reinforcing its positive aspects and creating new associations that allow Brazil to bring not only tourists but also residents, companies and investors for the country. These positive aspects, regarding the country citizens, can be their affability, hospitality, extraversion and generosity, which can improve the foreigners’ impressions on Brazil.
Originality/value
The originality of the study is to relate the concept of cordial man to the Brazilian people, showing the main features of their personality and also in the elaboration of an agenda indicating suggestions for future studies that relate the personality traits of Brazilian people with other areas.

Abstract
Purpose
The multiple factors of intelligence measurement are critical in intelligent science. The intelligence measurement is typically built as a model based on multiple factors. The different agent is generally difficult to measure because of the uncertainty between multiple factors. The purpose of this paper is to solve the problem of uncertainty between multiple factors and propose an effective method for universal intelligence measurement for the different agents.
Design/methodology/approach
In this paper, the authors propose a universal intelligence measurement method based on meta-analysis for crowd network. First, the authors get study data through keywords in the database and delete the low-quality data. Second, they compute the effect value by odds ratio, relative risk and risk difference. Then, they test the homogeneity by Q-test and analyze the bias by funnel plots. Third, they select the fixed effect and random effect as a statistical model. Finally, through the meta-analysis of time, complexity and reward, the weight of each factor in the intelligence measurement is obtained and then the meta measurement model is constructed.
Findings
This paper studies the relationship among time, complexity and reward through meta-analysis and effectively combines the measurement of heterogeneous agents such as human, machine, enterprise, government and institution.
Originality/value
This paper provides a universal intelligence measurement model for crowd network. And it can provide a theoretical basis for the research of crowd science.
