This research aims to identify the optimal configuration of investment which leads firms to their best competitive positions, considering the degree of concentration in the market.

The methodology was quantitative and based on secondary data with samples of 124, 106 and 90 firms from competitive environment classified as perfect competition, monopolistic competition and oligopoly, respectively. Proposed models' parameters were estimated by means of genetic algorithms.

Adjustments on firm's investment are contingent on the degree of competition they face. Results are in line with existing academic research affirmation that the purpose of investments is to create and exploit opportunities for positive economic rents and that investments allow firms to protect from rivals' competitive actions and reinforce the need for investment decision makers to consider the environment in which the firm is competing, when defining the amount of investment that must be done to achieve and maintain a favorable competitive advantage position.

This research brings two main original contributions. The first one is the identification of the optimal amount of capital and R&D investments which leads firms to their best competitive positions, contingent to the degree of concentration of the competitive environment in which they operate, and the size of the firm. The second one is related to the use of genetic algorithms to estimate optimization models that considers the three competitive environments studied (perfect competition, monopolistic competition and oligopoly) and the investment variables in the linear and quadratic forms.

This work aims to integrate the concepts generated by a systematic literature review on patient flows in emergency departments (ED) to serve as a basis for developing a generic process model for ED.

A systematic literature review was conducted using PRISMA guidelines, considering Lean Healthcare interventions describing ED patients’ flows. The initial search found 141 articles and 18 were included in the systematic analysis. The literature analysis served as the basis for developing a generic process model for ED.

ED processes have been represented using different notations, such as value stream mapping and workflows. The main alternatives for starting events are arrival by ambulance or walk-in. The Manchester Triage Scale (MTS) was the most common protocol referred to in the literature. The most common end events are admission to a hospital, transfer to other facilities or admission to an ambulatory care system. The literature analysis allowed the development of a generic process model for emergency departments. Nevertheless, considering that several factors influence the process of an emergency department, such as pathologies, infrastructure, available teams and local regulations, modelling alternatives and challenges in each step of the process should be analysed according to the local context.

A generic business process model was developed using BPMN that can be used by practitioners and researchers to reduce the effort in the initial stages of design or improvement projects. Moreover, it’s a first step toward the development of generalizable and replicable solutions for emergency departments.

This article aims to present aspects related to women’s personal life and work illustrated in the TV series Most Beautiful Thing (Coisa Mais Linda, in Portuguese).

To this end, a film analysis was carried out considering the first season of the TV series Most Beautiful Thing, and to analyze the data, qualitative content analysis was used according to Bardin (2006).

The analysis showed that women’s struggles were and are distinct. While white women are fighting for the right to work - concomitantly reconciling their roles as mother, wife and housewife -, black and poor women fight for survival and dignity. As result, the film analysis showed that women’s search for a different social position is related to an inherent cultural aspect. It is relevant to mention herein that this struggle remains up to the present; such struggle is characterized by the occultation of the social role played by women.

As a limitation, there are few studies that address the theme of white and black women during the period reported in the series.

The main contribution of this article is the use of a filming product that portrays the 1950s, but bringing current discussions on the role of women in society, especially regarding the labor market, the patriarchal domination of men, prejudice, racial, and class discrimination.

This study aims to analyse the efficiency of public higher education institutions (HEIs) through teaching and learning (T&L), research and technology (R&T) and social responsibility (SR) activities. It also aims to assess the external factors influencing the efficiency of T&L, R&T and SR, and influence of this efficiency on sustainable regional economic growth and innovation intensity.

The empirical approach is based on a two-step data envelopment analysis to compare the efficiency of 23 Portuguese public HEIs, using a Tobit regression, to assess the influence of the factors affecting HEI efficiency which in turn affects regional sustainability and innovation.

The results lead to the following conclusions: HEIs with better SR efficiency are situated in large urban centres; an insular location is positively associated with HEIs’ T&L and SR efficiency; HEIs’ T&L and SR efficiency positively influence regional gross domestic product (GDP); and HEIs’ R&T efficiency positively influences R&D in regional GDP.

This study offers implications in the domain of sustainable regional growth. The study recommends that the policies of HEIs should concentrate on developing activities that meet the needs of the region. It also emphasizes the need to invest in recruitment of qualified lecturers and researchers, and creation of relevant PhD positions. The study also emphasizes the need for government actions to consider the most disadvantaged regions and create infrastructure to attract new companies and people.

This study contributes to the existing literature on the efficiency of HEIs by considering the efficiency of not only T&L and R&T but also SR. It also analyses the influencers of both HEIs’ efficiency and regional development.

This paper examines how the Camburi Quilombo community in Ubatuba, Brazil, can be empowered to develop cultural resilience and conserve its Afro-Brazilian heritage in the face of challenges posed by climate change, urbanization and cultural erosion with the adverse consequences of tourism and inadequate infrastructure.

Emphasizing traditional knowledge, the project consisted of data collection, climate risk assessments and the development of an action plan in collaboration with academic institutions, governmental bodies and nongovernmental organizations (NGOs).

Aligned with sustainable development goals (SDGs), the project contributes to zero hunger, quality education, sustainable cities, climate action and life on land. Seed exchange fairs, decentralized seed banks and education initiatives foster environmental awareness and sustainable agriculture, impacting the community directly and over 1,000 individuals indirectly. While demonstrating short-term changes and mid-term viability, the project faced some challenges due to local communication complexities and overlapping jurisdiction.

Serving as a bridge between scientific research and local knowledge, the project aims to promote a paradigm shifts toward recognizing, respecting and incorporating indigenous practices, so that a more environmentally aware future can be envisioned for these communities amidst climate challenges. Reflecting on achievements, the project underscores integrating diverse cultural knowledge for community resilience.
