This teaching case was based on both primary and secondary sources of information. An interview with the entrepreneur and protagonist of the case was conducted, recorded and fully transcribed. Also, secondary data (digital and print media) were obtained from the interviewee, before, during and after the interview, as well as on governmental, institutional and company websites.

The Ninho da Águia Farm is a family business located in Minas Gerais and specialized in coffee production. Although founded in 1969 by Aides Gomes Monteiro, it was only when his surfer son Clayton Barbosa Monteiro took over the business that the small farm started focusing on specialty coffee, quality beans and international markets. With no formal education, Clayton managed to implement several managerial, organizational and strategic changes in the company, including its internationalization. Understanding the logic behind the development of the farm can help students understand several important concepts in International Business in relation to international entrepreneurs and effectuation/causation decision-making logics.

This teaching case was designed for graduate courses in international business/international strategy. But because of the richness of the case, it could also be used in other courses (e.g. marketing or international marketing). However, should this be the case, different teaching notes would be necessary.

The purpose of this paper is to achieve the multi-objective optimization design of novel tubular switched reluctance motor (TSRM).

First, the structure and initial dimensions of TSRM are obtained based on design criteria and requirements. Second, the sensitivity analysis rules, process and results of TSRM are performed. Third, three optimization objectives are determined by the average electromagnetic force, smoothing coefficient and copper loss ratio. The analytic hierarchy process-entropy method-a technique for order preference by similarity to an ideal solution-grey relation analysis comprehensive evaluation algorithm is used to optimize TSRM. Finally, a prototype is manufactured, a hardware platform is built and static and dynamic experimental validations are carried out.

The sensitivity analysis reveals that parameters significantly impact the performance of TSRM. The results of multi-objective optimization show that the average electromagnetic force and smoothing coefficient after optimization are better than before, and the copper loss ratio reduces slightly. The experimental and simulated results of TSRM are consistent, which verifies the accuracy of TSRM.

In this paper, only three optimization objectives are selected in the multi-objective optimization process. To improve the performance of TSRM, the heating characteristics, such as iron loss, can be considered as the optimization objective for a more comprehensive analysis of TSRM performance.

A novel motor structure is designed, combining the advantages of the TSRM and the linear motor. The established sensitivity analysis rules are scientific and suitable for the effects of various parameters on motor performance. The proposed multi-objective optimization algorithm is a comprehensive evaluation algorithm. It considers subjective weight and objective weight and fully uses the original data and the relational degree between the optimization objectives.

Mental health issues are concurrent among college students and new interventions are needed to address the problem. The objective of this study was to evaluate the convergence of symptoms into a single factor called “mental distress” and its relationship to mindfulness facets.

Brazilian university students (n = 136) answered self-report questionnaires, assessing sociodemographic information, dispositional mindfulness, insomnia severity, perceived stress, depression and anxiety. The analytical procedure consisted of defining the latent variable and relationships with mindfulness facets in a structural equations modeling environment.

The proposed model presented good fit [χ² (23 = 34.38; p = 0.060; RMSEA = 0.068 (90% CI = 0.00;0.114); CFI = 0.951] and mental distress was inversely related to the five facets of mindfulness questionnaire of nonjudgment and nonreactivity.

The symptoms converged into a latent variable, and the latent variable was related to the abilities of not judging and not reacting to internal stimuli. The relationships found might guide the development of future intervention strategies to benefit university students’ mental health.

This paper aims to answer the following question: Is PPP a financially viable alternative for the management of regional airports in Brazil?

The methodology is based on the case study of the innovative model of Zona da Mata Regional Airport management. It was used Value for Money as a method to compare this case with the conventional airport management alternative.

It was observed that, when compared to the airport management alternative through contracting third parties, the public–private partnership (PPP) provided a reduction of almost 70% of public spending on the management of this infrastructure. Besides the financial advantage, other benefits of this PPP contract were also observed.

The analyses carried out in this study are not exhaustive and can be improved and remade as the life cycle of the PPP contract studied is progressed.

It was concluded, from the results found, that PPP is an efficient alternative for the management of regional airports in Brazil, and the model can be replicated for similar airports.

When analyzing the results of this innovative project of managing a regional airport through a PPP, this work made it possible to measure the positive impacts of this alternative and demonstrate the potential of the PPP as an alternative for the management of other regional airports in Brazil.

This paper aims to analyse residents’ perceptions of tourism growth in Porto prior to the COVID-19 pandemic, aiming to determine the most appropriate strategies to mitigate negative tourism impacts. Studies on resident perceptions of tourism impacts are still scarce, particularly the ones addressing the topic in the context of Portuguese urban tourism areas.

Data was collected through an online survey, focusing on three categories of impacts: (i) economic, (ii) sociocultural (iii) and spatial-environmental, and the respective mitigation strategies, analysed from the perspective of Porto’s residents. Descriptive and bivariate statistics – T-test and Eta correlation – were used to analyse the collected data.

Respondents who live in the city centre experience specific tourism impacts more negatively, when compared to those living outside the inner-city area. Furthermore, no strong correlation is found between the said impacts and the respective mitigation strategies. However, creating awareness among tourists about acceptable behaviour in shared spaces is the strategy that stands out, as it has a medium correlation with all three impact categories. Most impact-strategy associations are weak, meaning that the defined strategies are not the most case-appropriate, which is something that policymakers should address.

To the best of the author’s/authors’ knowledge, this is the first study to adopt this approach in tackling the negative impacts of rapid tourism growth in Porto.

Product development process (PDP) in the context of Industry 4.0 may present several marketing implications. To understand these implications, the purpose of this study is to identify the benefits and difficulties of Industry 4.0 related to the PDP and its impact in marketing strategies and operations.

The methodology used to perform this research was a systematic literature review. For this, five steps were followed, namely, research question formulation; studies location; studies selection and evaluation; analysis and synthesis; and reporting and use research results.

The systematic literature review considering PDP in Industry 4.0 context resulted in 28 benefits and 14 difficulties, in a total of 53 articles. From the analysis of these benefits and difficulties, several implications for marketing were identified, namely, better understand customer preferences; greater agility in marketing decision-making; better align marketing, product development and operations processes issues; better understand product/service lifecycle; analyze possibilities of new ways of distribution and communication channels; better define the value of products and services and location requirements.

The findings presented here can be used both by market professionals, interested in the subject and by researchers for future studies. The better understanding of PDP in the context of Industry 4.0 can enhance marketing strategies for market professionals and provide insights for researchers. No similar studies were found in the literature.

This paper is dedicated to elaborating, proposing and validating an action plan to enhance the mitigation of risks generated by the COVID-19 pandemic in the electric sector supply chain, aiming to promote a more resilient supply chain.

For this, a systematic review of the literature was carried out to prepare an action plan that was validated by a group of experts, through the Delphi methodology.

As a result, an action plan was obtained, with 18 actions subdivided into 13 resilience elements and related to 20 main risks arising from the pandemic. The actions oriented to the development of relationships among supply chain members, promotion of a culture oriented to learning and problem solving, contingency plan, safety stock and risk management were pointed as those capable of generating resilience in the chain analyzed in the moment of crisis.

The results achieved can contribute to the expansion of debates in the area of resilient supply chain management, as well as contribute to supply chain managers in their elaboration and definition of actions that aim to make the supply chain more resilient. It is noteworthy that no similar study was found in the literature considering the specificities of supply chain management in the Brazilian Amazon region.
