The purpose of this article was to evaluate the causal influence of Lean management practices on knowledge waste within the context of higher education institutions (HEIs). The peculiarities of knowledge impress upon organizations the need to think about reducing knowledge waste as a crucial practice. The Lean philosophy and practices therefore stand out as an appropriate management perspective, particularly given Lean's focus on waste elimination. However, little is known about the influence of Lean practices on reducing knowledge waste.

A quantitative research instrument was distributed to professors and technical and administrative staff across three types of HEI in the State of Rio Grande do Sul, Brazil. The validated and pretested survey was circulated to the target population via an online method to explore eight constructs and 38 items concerning Lean and knowledge and waste.

The results of the survey indicated that all hypotheses were supported. The sum total of 837 responses showed that the Lean relationships (internal organizational paths) were more obvious where leadership support proved to have a positive effect on continuous improvement, training, and customer involvement. Moreover, the significant and negative effects of the Lean practices studied on knowledge waste was also supported, including for example, the interaction between HEIs and its client base.

HEIs are knowledge generators. Therefore, the necessity of avoiding and reducing knowledge waste is even greater. This study also differentiates itself from the “traditional” knowledge loss studies by investigating knowledge while the employees are still part of an organization and not after they have left taking the knowledge away with them.

This study aims to investigate the occurrence of the decoy effect in stock investment decisions based on fundamental analysis.

In this study, the decoy effect was investigated by applying two questionnaires, one of them with the presence of a decoy alternative, to a set of 224 respondents with knowledge of business fundamentals, simulating investment decisions in stocks of companies listed on the Brazilian Stock Exchange. The data analysis was performed using the Fisher's exact test, Student's t-test and ANOVA. The research also aimed to detect a potential relationship between the variables gender, age, degree and professional experience with the type of decision made.

The results pointed to the occurrence of the decoy effect when analysing the general response data. However, such evidence was not confirmed when the sample was analysed by classes (gender, course, age and professional experience). There is no statistical evidence that the decoy effect influences classes.

The recent decoy effect literature is little explored in investment decision-making. This study is unique in examining the decoy effect in investment decisions in the Brazilian context.

The main factor that leads organizations to implement Building Information Modeling (BIM) is customer demand. While this is a frequent topic in the BIM literature, few studies address BIM organizational readiness. Due to this gap in BIM implementation literature, this paper aims to understand what affects organizational BIM readiness and how the BIM readiness process occurs.

The present paper adopts design science research as a methodological approach. A literature review examined 69 journal articles. The analysis focused on multiple theories, such as organizational readiness for change, adoption and diffusion of innovations and project management.

By investigating BIM organizational readiness, this study presents a construct and a conceptual model for driving BIM readiness.

This study can benefit researchers and organizations. The results presented may drive further research and discussions on the topic. But it is important to state that these results must be tested on real situations.

The objective of this study was to assess the incorporation of polyunsaturated omega 3 and omega 6 fatty acids in the eggs of Japanese quails (Coturnix coturnix japonica) fed with soybean, flaxseed and shark liver oils, as well as to assess their effects on the chemical composition and lipid quality of the yolks.

The total of 252 units of quails were distributed in a completely randomized design with seven treatments and six replications, totaling 42 experimental design units. The sources of oils and their inclusions in the experimental diet were 2% of soybean oil (S), 2% of flaxseed oil (L) and 2% shark liver oil (T), obtained from the species Carcharhinus acronotus, and the mixtures of 1% S + 1% L (SL); 1% S + 1% T (ST); 1% L + 1% T (LT) and 0.67% S + 0.67% L + 0.67% T (SLT).

The proximate composition of the egg yolk was not changed to the supplementation of lipid sources added in quail diet. The total replacement of soybean oil by shark liver oil reduced the cholesterol content in the yolk by 19% (T = 282.97 mg cholesterol/100 g egg) and the addition of flaxseed oil produced eggs with greater amount of polyunsaturated fatty acids (PUFAs) (LS = 18.32%). The treatments with flaxseed oil and its mixtures (soybean oil + flaxseed oil and flaxseed oil + shark liver oil) effectively contributed to reducing the ω-6:ω-3 ratio and enriching the quail eggs with PUFAs, especially linolenic acid (18: 3n3c) and EPA (20: 5n3c).

Thus, manipulation in the diet of quails enriched the content of essential PUFAs and reduced the cholesterol content in the yolk. The flaxseed oil was the lipid source that influenced to improve the quality of the egg yolk. These results have practical applicability for the quail egg industry.

This paper aims to evaluate the current level of knowledge about lean construction (LC) practices in construction companies, universities and class organizations in Brazil and identify the barriers to implementing LC in the Brazilian construction industry and prioritize them through comparison with global challenges.

This multiple case study was carried out through a questionnaire answered by 56 construction companies, 15 universities and 10 professional associations. The questionnaire evaluation allowed the authors to determine the level of knowledge about the LC, its adoption and barriers to its adoption in the Brazilian industry. The results were statistically analyzed using the weighted average (MIS) of results using the Kruskal–Wallis test, which compares sample distribution among groups, and Cronbach’s alpha test to measure the questionnaire reliability.

This study points to universities as the main ones responsible for the low adoption of LC in Brazil and points to the need for an integrated action among construction companies, universities and class organizations to overcome the traditional project management culture and raise the level of knowledge about LC.

This study evaluated the current LC situation in an emerging country, Brazil, and compared it with the principal international challenges observed in studies of other developing countries – China, India, Morocco, Saudi Arabia and Singapore – least developed countries – Bangladesh and Nigeria – and developed country – UK. These studies evaluated construction companies located in the listed countries. Based on that, 22 international challenges were established for the LC adoption. Additionally, this research also evaluated universities and working-class organizations in addition to construction companies. This addition can contribute to a better result understanding that can be explored by Brazil and other countries.

This study analyzes, from the perspective of social exchange theory, the influence of empowering leadership on contextual performance mediated by perceived organizational support (POS) and affective organizational commitment (AOC).

A survey was carried out with 182 employees of the Best Companies to Work in Brazil. Data analysis was performed by structural equation modeling (SEM) and by fuzzy set qualitative comparative analysis (fsQCA).

Results demonstrate that empowering leadership directly influences higher contextual performance and indirectly through the mediation of AOC, but not through POS. Serial mediation confirms that the model's variables self-promote each other to ultimately foster higher performance. Furthermore, all solutions to obtain high contextual performance include empowering leadership in the dimension of trust in the high performance of employees.

The statistical support for the serial mediation indicates that empowering leadership promotes POS, which influences AOC that finally promotes the employee's contextual performance. However, this study's model does not include employees' task performance; our results add to the contextual performance literature.

The study highlights the role of the empowering leadership style in the organizational context, an aspect that deserves attention from the managers and organizations due to its effect on employee performance.

The study adds a new framework to the literature, which can be used by organizations to promote contextual performance. The variables, which include contextual and individual factors, foster the employee's contextual performance in a joint and self-promoting way. Contextual performance exceeds the manager's technical attributions; it covers psychological and discretionary behaviors.

The evolution of e-health technologies presents promising alternatives for health-care excellence. Despite the benefits arising from mobile e-health (m-health) and wearables technologies, the literature stands many contradictories signs regarding how users accept and engage in using these technologies. This study aims to synthesize the estimations about m-health user acceptance technologies.

A meta-analytic structural equation modeling was carried out using the 778 relationships estimated by 100 previous research. The estimations follow the relations and constructs proposed in the UTAUT2 technological acceptance model.

The results indicate the performance expectancy, effort expectancy, social influence and habit constructs are most important for predicting the behavioral intention of use of m-health technologies. The Latin American users of e-health technologies are still underestimated in the literature.

The study presents a guide to understanding the acceptance process of m-health technologies and delivers a general orientation for developing new m-health devices considering their acceptance by users.

This paper aims to analyze the influence of technology-based business incubators (TBIs) on the resources of technology startups in Brazil. The authors identify which resources are offered and explore the importance of resources for TBIs and startups. The theoretical background is based on the resource-based view, the resource dependency theory and total factor productivity.

The study is characterized by a descriptive approach. The method includes a multiple case study and a survey. For data collection, we conducted interviews with three managers from TBIs and distributed questionnaires to 30 startup founders. The content analysis supports the identification of the resources, while the quantitative approach explores the relationship between total factor productivity and resources.

Resources are the linkage between startups and TBIs, promoting the development and continuity of these organizations. Among the resources offered by TBIs, the most representative is physical resources, due to the early stage of startups. TBIs do not offer financial resources directly but facilitate access through networks with other actors.

The research implications depict the importance of resources as a link between TBIs and startups. The results highlight how TBIs play an important role in promoting entrepreneurship and innovation in the context of emerging economies such as Brazil.

This article performs a multi-theoretical analysis, addressing the perspectives concerning resources. No previous study has used this combination of perspectives to analyze the relationship between TBIs and startups in Brazil, filling the gap about this subject in emerging economies.
