Abstract
A numerical technique is described for the analysis of multiple interacting deformable bodies undergoing large displacements and rotations. Each body is considered an individual discrete unit, which is idealized by a finite element model. Discrete finite element models interact with their surroundings through contact stresses, which are continually updated as the elements move and deform. The method of analysis consists of a finite element formulation based on a generalized explicit updated Lagrangian method. This formulation is a general finite element formulation, that permits the large deformation analysis of both continuum and discontinuum systems. Different validations of the proposed method of analysis, including cases that involve very large rotations, as well as some examples that demonstrate the application of the discrete finite element method to problems in rock mechanics are presented and discussed in the paper.

Abstract
Purpose
The aim of this study is to evaluate the implicit and explicit attitudes of Generation Z (Gen Z) individuals toward the experience of visiting and getting to know traditional or virtual museums.
Design/methodology/approach
Two studies were conducted. The first study assesses the implicit attitudes of Gen Z individuals through Implicit Association Tests (IAT) toward the experience of visiting traditional versus virtual museums. Considering the results of the study one, the second study proposes and validates a conceptual model through PLS-SEM approach about the explicit attitudes of this generation toward virtual museums.
Findings
In the first study, it was found that virtual museums are more successful at engaging and immersing participants than traditional museums for Gen Z. The second study emphasized the significance of meeting Gen Z expectations and ensuring effortless access to information in virtual experiences as this can lead to increased satisfaction and inspiration among this generation.
Originality/value
The originality of this study lies in its focus on Gen Z's attitudes toward virtual museums and the use of both implicit and explicit attitude measures to gain a comprehensive understanding of these attitudes. An interesting aspect emerges from the implicit attitudes displayed by Gen Z, indicating their preference for virtual museums as more captivating compared to traditional ones.

Abstract
The immersion of global higher education in a competitive, economy-oriented paradigm calls for perspectives on internationalisation that are explicitly aimed at shaping cooperative, sustainable and alternative/decolonial futures. The authors of this chapter recognise the relevance of research perspectives that – epistemologically aligned with critical internationalisation studies – emphasise the dilemmas and contradictions of internationalisation of higher education (IHE). In this chapter, the authors therefore present reflections that confront the hegemonic discourse that portrays the phenomenon of IHE as an unconditional good. The authors dialogue with the idea of promoting a perspective of IHE from and for the Global South – that is, one that instead of suppressing, recognises the epistemic plurality of the world. To do so, the authors assume that any critical efforts to address internationalisation in the context of the Global South can be enriched when explicitly situated within colonial history. The authors argue that looking towards the future of IHE requires a look towards its past. Specifically, the authors bring together four interrelated lines of argument: (i) recognising the university as a historical producer and reproducer of colonial hierarchies; (ii) conceiving the Global South as a field of epistemic challenges; (iii) having a non-myopic view of South–South cooperation; and (iv) spreading the epistemological horizon of internationalisation. Such reflections might contribute to envisioning new horizons for IHE in the Global South and its relation with those who have been relegated to a status of invisibility.

Abstract
Purpose
This study aims to investigate whether Brazilian companies have increased their reporting on biodiversity within the past decade and whether reporting practices are linked to the government's stance on environmental protection, media coverage and industry biodiversity risk.
Design/methodology/approach
Using content analysis and ordinary least squares regression models, the authors examine sustainability reports from Brazilian listed and non-listed companies from 2010 to 2020.
Findings
This study’s empirical analysis indicates that companies have decreased their reporting on biodiversity over the decade. Findings suggest that biodiversity reporting is associated with the level of scrutiny from external constituents, such as industry biodiversity and the president's own public policy agenda and partially by media coverage.
Originality/value
The literature seems to lack an understanding of how political factors may drive social and environmental reporting practices, especially biodiversity reporting. This study addresses this issue by examining the relationship between the government's stance on environmental protection. By focusing on biodiversity reporting in an emerging country like Brazil, this study also generates insights into a highly impactful yet under-researched context.

Abstract
Purpose
This article unveils the governance dynamics of a frontier region for global value chains (GVCs). For this purpose, we developed a replicable methodology to analyze the interaction between public policies and the governance of GVCs to better assess sustainability impacts and business responses. We apply this methodology to understand the governance dynamics in the beef cattle GVC in the Brazilian Amazon. In Brazil, cattle ranching increasingly concentrates in the Amazon region, notably in the state of Pará, becoming the major driver of deforestation as public policies and law enforcement are ineffective. Using our methodology, we were able to identify the main weaknesses in governance pertaining to sustainability in the beef GVC.
Design/methodology/approach
The methodology employed a case study approach and utilized GVC mapping and analysis using primary (semi-structured interviews and site visits) and secondary data sources. The governance structures along the GVC were characterized. Finally, the sustainability and upgrading within and beyond the GVC were analyzed.
Findings
Based on our methodology, emerging beef GVCs, such as those in Santarém, Pará State, primarily supply the domestic market without external pressures to improve sustainability. This fact coupled with a lack of local capacity to implement public policies presents challenges for sustainable governance. Efforts to enhance the performance of the value chain predominantly stem from private sector capacity-building initiatives targeting ranchers.
Originality/value
Through the development of our method, the governance of the Brazilian beef GVC in the Amazon is mapped and analyzed. This study introduces a novel sustainability-focused GVC mapping methodology aimed at establishing a standardized framework to enhance the comparability of research. As a result, this study offers useful theoretical and empirical contributions to the literature on the sustainability of GVCs in frontier regions where public governance capacity is low.

Abstract
Purpose
The purpose of this paper is to review the topic “urban green space” focusing on its social benefits and measure techniques in terms of monetary value and accessibility. It suggests potential research direction by using an integrated valuation and measurement framework, and concludes that urban green space valuation in the providers’ perspective as well as accessibility analysis in the consumers’ perspective are useful tools that provide significant measure techniques in urban green space planning.
Design/methodology/approach
The paper uses a systematic approach to build up a conceptual framework that quantifies social benefits of green space from provider and consumer perspectives. The literature review indicates some limitations of existing techniques of valuation and accessibility analyses, which entails an integrated model of measurements.
Findings
The paper explores social benefits of urban green space, which includes recreational opportunities, aesthetic enjoyments, adjusting psychological well‐being and physical health, enhancing social ties, and providing educational opportunities. To analyze existing evaluation and measure techniques of urban green space, the paper points out that a single measurement only evaluates certain aspects of urban green space, which may not always be suitable to comprehensively assess social benefits from both providers’ and consumers’ perspectives. Considering this limitation, the paper offers an integrated model to measure urban green space that may deal with current limitations.
Originality/value
The originality of the study resides in designing an integrated model including valuation and measure techniques. It certainly offers an important avenue to evaluate social benefits of urban green space.

Abstract
Purpose
The purpose of this article is to investigate how social integration, immigrant networks and barriers to ventureing affect the entrepreneurial activities of Brazilians in Canada, indicating how mixed embeddedness takes place in that context.
Design/methodology/approach
Data were collected in Toronto, through the application of a survey with 74 Brazilian entrepreneur respondents and 42 semi-structured interviews with selected subjects, thus representing a multi-method approach. The analysis included descriptive statistics from the survey data and a qualitative analysis of the trajectories and life stories of Brazilian immigrants.
Findings
Our sample comprises respondents with a high level of education and proficiency in English, coming predominantly from the southeast of Brazil, white, aged from 30 to 49. The majority of businesses are small and related to the service sector. The article contributes to the literature by discussing the elements related to mixed embeddedness, including the need for cultural adaptation and for the creation of networks as a crucial element for business venturing.
Research limitations/implications
The study focuses on entrepreneurs regardless of their businesses sector or formality/informality status. It could be used as an instrument to support Canadian public policies for welcoming Brazilians and for the Brazilian government to prevent the evasion of potential entrepreneurs.
Originality/value
The article contributes to the body of knowledge of immigrant entrepreneurship in Canada and of Brazilian entrepreneurship overseas. The results suggest factors that may be relevant to the expansion of their business, such as social networking, cultural embeddedness and adaptation of the products/services to a wider range of target customers.

Abstract
Purpose
Considering the importance of financial literacy (FL) in people’s lives the goal of this study aims to assess the level of FL of young Portuguese students, addressing the impact of the level of education on the FL of college students.
Design/methodology/approach
Data from a non-probabilistic sample of 185 students attending higher education bachelor’s and master’s degrees courses in Economics, Management and Marketing was collected between February 25 and March 23, 2019, using an online questionnaire. Descriptive and inferential statistics were computed using IBM SPSS 25 to analyze the data.
Findings
The findings show that the level of the degree (bachelor’s or master’s degree) and the academic background of the individual’s parents have a positive impact on FL. Moreover, among individuals with a high level of FL, gender and professional situation are additional predictors. Furthermore, the authors observed that the level of FL of Portuguese students attending higher education is overall low, especially in terms of their knowledge of the main financial concepts, which may call for public policies to be implemented so that to reduce this vulnerability.
Research limitations/implications
Among limitations is the limited sample collected, restricted to a particular target, Portuguese students attending business-related courses such as Economics, Management and Marketing, either studying for a master’s or bachelor’s degree. This issue restricts the generalization of the overall findings to other students studying different fields. Future studies can collect a random and representative sample.
Practical implications
This study test can be replicated to generate a diagnosis in any region or country, identifying how financially literate the region under analysis is. Also, this can be done to verify the evolution of FL after educational interventions.
Social implications
FL is an important competence. In fact, youngsters in the whole world have been suffering from a lack of financial knowledge (FK), and some characteristics of them can push them into indebtedness, and, even bankruptcy, such as a higher level of status consumption, the tendency to have an attitude of self-appraisal, to be self-centered, to seek instant gratification. This study helps to lead to a better understanding of this phenomenon.
Originality/value
Addressing college students attending different levels is an add-on to the existing body of literature. This paper contributes to study differences in FL between college and master students, enlightening and evaluating the role of scholarship maturity on financial education. Furthermore, some of the findings challenge the extant knowledge regarding the influence of professional experience, gender and age on the level of FK that students have. Finally, the current approach is innovative as it addresses FK, FL and numeracy in the same study.

Abstract
Purpose
The increase in demand for health services requires companies in the segment to seek management tools and techniques that focus on reducing waste such as waiting, unnecessary displacement and low people productivity. The purpose of this paper is to present the value stream mapping (VSM) of patients at an occupational medicine clinic, proposing a new scenario with the aid of the simulation of discrete events to reduce the total waiting time during the patient's journey.
Design/methodology/approach
The methodology consisted of a case study developed in an occupational health clinic, involving the analysis of the patients' arrival times, time of attendance, number of employees and their functions. Data collection considered 100 random samples from the patients' arrival interval and 40 random samples for each of the operational processes performed by the clinic in a work shift. The collected data served as input for the simulation of scenarios and prioritization of the times for the proposal of the future VSM.
Findings
With the study it was possible to propose the reduction of time wasted in the patient's journey, mainly the waiting times (37.92%) and the lead time (29.86%), making it possible for the patient to go through the entire process without waiting for queues. In addition, the increase in employee productivity and efficiency in patient care during the work shift is considered.
Research limitations/implications
Despite the considerable gains obtained with the realization of this study in relation to the processing times, total waiting time and lead time, the analysis was not considered, the mode of execution of the processes performed by the professionals and the influence of the layout to improve the flow of patients, being some of the challenges for future studies to consolidate lean culture in the health segment.
Practical implications
The simulation of discrete events indicated that it is possible to attend a larger number of patients with the same professional structure, in case the delay in the arrival time of doctors and speech therapists is resolved. There was a reduction in the average total waiting time of 37.92%, a reduction in lead time to 29.86% and identification of the steps that most contributed to the increase in queues for patients in a 05:30 min work shift.
Originality/value
The work proposed the constitution of a VSM based on a discrete simulation with data from the entire health unit system, considering everything from the reception for patient registration, collection of laboratory and image exams to medical assistance. The work differs from the others in that it considers the patient's entire journey in the occupational medicine clinic, instead of prioritizing only one service department. The analysis of the results considered the scenario that presented the maximum efficiency of the available resources, respecting the patient's individualized care times, which is one of the complaints of the therapeutic teams to the use of standardization by the VSM.
