The purpose of this paper is to describe an integer linear programming model to schedule the maintenance crew and the maintenance tasks in a bus operating company.

The proposed methodology relies on an integer linear programming model that finds feasible maintenance schedules. It minimizes the costs associated with maintenance crew and the costs associated with unavailability. The model is applied in a real-world case study of a Portuguese bus operating company. A constructive heuristic approach is put forward, based on solving the maintenance scheduling problem for each bus separately.

The heuristic finds better solutions than the exact methods (based on branch-and-bound techniques) in a much lower computational time.

The results suggest the relevance of such heuristic approaches for maintenance scheduling in practice.

This proposed model is an effective decision-making support method that provides feasible maintenance schedules for the maintenance technicians and for the maintenance tasks in a fleet of buses. It also complies with several operational, technical and labour constraints.

The main aim of this chapter is to analyse whether recent economic developments in Central and Eastern European countries have been subjected to a typical process of Dutch Disease (DD). We investigate the impact of foreign aid and other external inflows on the economies of these countries through their effect on the real exchange rate (RER).

After a review of the literature on the DD, we apply robust new generation augmented Dickey-Fuller (ADF) tests, and autoregressive distributed lag models following the methodology of Arellano and Bond (1991) and Blundell and Bond (1998) to establish the impact of capital inflows on output growth for the period 2003–2013.

We find no significant role for financial costs in the determination of the RER in the integration process of these countries. The evidence supports a positive influence of external capital inflows, and in particular European structural funds, on the determination of RER. This positive influence also extends to non-tradable goods and public investments.

In order to promote medium-long run sustainability, Central and Eastern European countries should carefully apply European funds in a way that does not bring about higher internal prices, or, if possible, control the nominal exchange rate in accordance. They must invest more in the higher qualification of human resources, research and development, innovation, entrepreneurship and industrial clusters, in view of the development of the tradable sector.

It is the first chapter that analyses the presence of DD originated by European structural funds and external inflows of funds for this group of countries.

We present a critical literature review debating Brazilian research on social and environmental accounting (SEA). The aim of this study is to understand the role of politics in the construction of hegemonies in SEA research in Brazil. In particular, we examine the role of hegemony in relation to the co-option of SEA literature and sustainability in the Brazilian context by the logic of development for economic growth in emerging economies. The methodological approach adopts a post-structural perspective that reflects Laclau and Mouffe’s discourse theory. The study employs a hermeneutical, rhetorical approach to understand and classify 352 Brazilian research articles on SEA. We employ Brown and Fraser’s (2006) categorizations of SEA literature to help in our analysis: the business case, the stakeholder–accountability approach, and the critical case. We argue that the business case is prominent in Brazilian studies. Second-stage analysis suggests that the major themes under discussion include measurement, consulting, and descriptive approach. We argue that these themes illustrate the degree of influence of the hegemonic politics relevant to emerging economics, as these themes predominantly concern economic growth and a capitalist context. This paper discusses trends and practices in the Brazilian literature on SEA and argues that the focus means that SEA avoids critical debates of the role of capitalist logics in an emerging economy concerning sustainability. We urge the Brazilian academy to understand the implications of its reifying agenda and engage, counter-hegemonically, in a social and political agenda beyond the hegemonic support of a particular set of capitalist interests.

This study aims to develop a scale using item response theory (IRT) to assess the entrepreneurial potential for digital transformation in Brazilian companies.

IRT was used to develop a scale for entrepreneurial potential in digital transformation. This scale was constructed from a questionnaire, covering the domains: (1) data-driven culture, (2) openness to knowledge and adaptation to change, (3) connectivity and (4) creativity and innovation. The questionnaire was administered to a sample of 216 entrepreneurs from small business enterprise (SBE) and startups in Brazil.

A questionnaire was developed and validated to assess the latent trait of entrepreneurial potential within the context of digital transformation. Additionally, a three-level scale of entrepreneurial potential was established: low (level I), intermediate (level II) and high (level III). The interpretation of this scale provides valuable information on which domains, such as data-driven culture, innovation, among others, can be enhanced to improve the potential of entrepreneur for digital transformation.

The sample was limited to small Brazilian companies and startups, which may restrict the applicability of the results to other business or geographic contexts. Additionally, the items evaluated in the scale may not fully capture all nuances of entrepreneurial potential for digital transformation. Future research should consider including new items that cover a broader range of entrepreneurial characteristics.

The findings of this study have significant practical implications for the Brazilian entrepreneurial ecosystem, the entrepreneurs themselves, public policy makers and entrepreneurship support institutions. These results can guide digital transformation strategies, adjustments in public policies and investments, thereby promoting economic development and innovation in the country.

This study stands out for using IRT as a robust methodology to develop an interpretative scale to assess entrepreneurial potential in the digital transformation era. By focusing on Brazilian SBEs and startups, the study offers an original contribution on how these companies are handling the challenges of digitalization and identifying areas for improvement to further promote digital transformation among entrepreneurs.

This study aimed to develop a psychometrically reliable job satisfaction (JS) measure for university employees, guiding administrative decisions and monitoring satisfaction over time in public universities.

A JS survey developed by a Brazilian federal university’s sustainability committee containing 58 items across physical, cognitive and organizational domains was longitudinally tested with 1,214 responses collected. The data were analyzed using Item Response Theory (IRT) analysis, employing the Graded Response Model, with tools such as frequency analysis, item characteristic curve, and full-information factor analysis in RStudio. The scale’s criterion validity was also established via expert qualitative interpretation.

The instrument’s internal consistency was confirmed as the results demonstrated its high reliability with a marginal reliability coefficient of 0.95. Significant findings revealed that recognition and supervisor relationships were key discriminators of JS and that workers began to perceive satisfaction when basic environmental conditions were met.

It is important to mention that the application of this scale is specifically limited to higher education institutions and may not be directly applicable to other educational settings or industry sectors without modifications.

Although numerous measures and scales have been developed to assess JS, one elaborated by using IRT in a public university environment was lacking. Due to shifting dynamics in the workplace, traditional measurement of JS has proven inadequate, necessitating a more precise, accessible and updated tool. The developed scale allows precisely targeted interventions to improve JS and can be reapplied to evaluate their effectiveness. This research thus contributes a valuable tool for academic organizational psychology, enhancing the understanding of the measurement of JS.

This work aims to identify the linear elastic orthotropic material paramters of Pinus pinaster Ait. wood, using full-field measurements and an inverse identification strategy based on the finite element (FE) method updating technique.

Compression tests are carried out under uniaxial and quasi-static loading conditions on wood specimens oriented on the radial-tangential (RT) plane, with different grain orientations. Full-field displacements and strains are measured using digital image correlation (DIC), which are then used as a reference in the identification procedure. A FE model is implemented assuming plane stress conditions, where wood is modelled as an orthotropic homogeneous material. Based on the numerical results, a synthetic image reconstruction scheme is implemented to synthetically deform the reference experimental image, which is then processed by DIC and further compared to the experimental results.

The results for both approaches were similar when both specimen configurations were used in a single run. However, when using the DIC-based FEMU approach with the on-axis configuration, the identified modulus of elasticity in the tangential direction and shear modulus are closer to the reference values.

This approach ensures a fair comparison between both sets of data since the full-field strain maps are obtained through the same filter and therefore have the same strain formulation, spatial resolution and data filtering. Firstly, the identification is performed using a single configuration, either the on-axis or the off-axis specimen. Secondly, the identification is carried out by merging data from both on-axis and off-axis configurations.

The coronavirus disease (COVID-19) pandemic generated a worldwide financial crisis by impacting several links of the supply chain, however companies can take advantage by quantitatively measuring the disruptive impacts.

This study sought to develop the failure mode and effect analysis and supply chain resilience (FMEA-SCR), a hybrid tool developed using a potential failure mode and effect analysis (FMEA) applied to supply chain resilience (SCR) and taking into account the capability factors and business processes.

In order to validate, the proposed model was applied into two different organizational study cases: an university and a cooperative managing urban solid wastes with recyclable potential (MSWRP). Through the procedures described here any organization can understand and assess in a simplified way the impacts over their supply chain generated by such a crisis.

This study synthesizes three different procedures into a single method called FMEA-SCR, allowing organizations to understand and assess in a simplified way, the impacts over their supply chain generated by COVID-19. To this end, it brought together the studies developed by Rajesh and Ravi (2015) and Curkovic et al. (2015), on possible causes of disruptions in SC, the capability factors of Pettit et al. (2010) used by organizations to mitigate the effects of disruptions, besides Lambert's and Croxton (2005) business processes, thus weaving a method that allows organizations to visualize, analyze and classify the pandemic impacts over their supply chain.

The purpose of this paper is to analyse professionals’ competencies in supply chain management (SCM) in the mid-sized supermarket sector in Brazil as a way of broadening the understanding of the importance and the use of competencies in business development.

The survey was conducted with 60 managers from 34 companies in the mid-sized supermarket sector in the metropolitan region of Natal, Brazil. The managers evaluated the importance and use of a set of 24 general and specific competencies related to SCM. The gaps between importance and use were identified and analysed.

The results showed that the level of use was below the level of importance for all competencies, and the general competencies somehow received more attention than specific competencies in the development and execution of SCM activities. Moreover, the overall average of the gaps between levels of use and importance calculated for the general competencies was less than the general average of the gaps calculated for the specific skills.

The research was carried out with a sample of mid-sized supermarkets in a particular region. Therefore, it is recommended that the research be extended to other contexts and supermarket companies of other sizes.

The calculated gaps between managers’ expectations or attributed importance and the perceived levels of competence use in supermarket organisations revealed important lines of action for correcting the course in human resources policy.

The present paper elaborated on an opportunities matrix, gaps × importance, showing how managers can set priorities to fill competence gaps and improve the companies’ human resources. Besides, it compares levels of importance and uses for two groups of competencies, general and specific related to SCM.

This study aims to examine the characteristics of scientific publications that address the management of higher education institution (HEI) libraries from a sustainability perspective, through a bibliometric analysis, to contribute to the development of knowledge and to identify opportunities for further research.

The knowledge development process-constructivist instrument was used to select a portfolio of 24 articles that are scientifically acknowledged and aligned with the theme “Sustainable Management of Libraries in Higher Education Institutions” and delimited by the authors. This study, guided by a constructivist perspective, was carefully conducted to discern selections that differ from traditional definitions. The analysis followed a qualitative approach and used the following variables: fruitful authors, connection networks between authors and vision of sustainability (the degree of dimensional coverage).

The analysis of the literature highlighted the partnerships of authors from countries belonging to the American continent as the most involved in research on the subject and the evolution from a one-dimensional view – centred on the environment – to a multidimensional view.

The understanding is that library management in HEIs, from a sustainability perspective, is an essential aspect of institutional legitimacy for the stakeholders. Therefore, sustainability should be treated in a multidimensional way and integrated with the institution’s values.

The activities carried out in ports are disruptive to the environment where they are located. Therefore, the objective of this work is to analyze the presence of corporate social responsibility (CSR) in the missions and visions of the main ports of Latin America.

A qualitative technique of content analysis was applied to the missions and visions of 72 ports in Latin America. First, the missions and visions of the ports were collected (72). Second, it was assigned a value 1 if the mission had any evidence of CSR, 0 if it had no evidence and “-” if the mission was not found. The same procedure was performed with the visions.

Results indicate that 20.83% of the ports allude to CSR in their missions, 34.72% of the ports allude to it in their missions and visions and 13.88% only allude to it in their visions (22 ports did not mention it in their missions or their visions). So, the main findings indicate that in Latin America the majority of ports do not consider elements of CSR in their missions and visions.

This paper is mainly focused on covering two gaps in the literature: first, to increase knowledge about the strategic bases of ports in Latin America through their missions and visions; and second, to visualize the coherence of the missions and visions with the activities of CSR.
