This paper aims to develop a stable gel-type lubricant emulating commercial conditions. This encompassed rheological and tribological assessments, alongside field trials on the Medellín tram system.

The gel-type lubricant with graphite and aluminum powder is synthesized. Rheological tests, viscosity measurements and linear viscoelastic regime assessments are conducted. Subsequently, tribological analyses encompassing four-ball and twin disc methods are executed. Finally, real-world testing is performed on the Medellín tram system.

An achieved lubricant met the stipulated criteria, yielding innovative insights into the interaction of graphite and aluminum powder additives under varying tests.

Novel findings are unveiled regarding the interaction of graphite and aluminum powder additives in tribological, rheological and real-world trials. In addition, the wear behavior of polymers is observed, along with the potential utilization of such additives in tramway systems.

This paper aims to find the incidence of university sustainability, as sustainability practices, in university performance at private universities.

Quantitative research using structural equation modelling. Data collection and analysis followed sustainability and performance scales from previous research. The scales were validated by surveying students, teachers and administrative staff of five private universities in Medellin, Colombia. The responses (i.e. 5,344 useful answers) were collected between April 2019 and December 2020 and analysed using the Smart partial least square (PLS) software and the PLS calculation methodology.

The results confirmed the reliability and validity of the sustainability and performance university measurement models and validated the dimensions proposed to determine sustainability and performance holistically in private universities. The results confirmed that universities implementing sustainability holistically in their system positively impact their performance as higher education institutions. The university sustainability is forecasting the University Performance in about 60% of the universities analysed, with a considerable contribution from sustainability in outreach and strategic management.

This study was cross-sectional and empirically validated the model of sustainability and performance at five private universities in a single period and territory. A broader validation from longitudinal studies considering other universities in Colombia and Latin America is suggested to understand local and regional trends better.

Results provided a model for better understanding the incidence of sustainability in performance holistically at private universities in developing countries such as Colombia. In addition, the proposed dimensions and model could help regional decision-making on higher education.

To the best of the authors’ knowledge, this paper is one of the first attempts relating a structural equation model and inter-university research on the incidence of sustainability in private university performance. This work contributes to a local consensus on sustainability and performance models at private universities. Furthermore, from this research emerged a joint policy framework for incorporating sustainability holistically and regionally as an effective strategy for universities and their commitment to sustainable development.

In the current labour context, employability is an important tool for recently graduated who are entering the labour market and must face major challenges that include a decrease in job opportunities, the rapid evolution of technology, and the need for lifelong learning.

This study analyses the impact of the socio-emotional competencies of 470 senior students and graduates of five engineering majors at a higher education institution in Medellín, Colombia. In the sample examined, the data were analysed using inferential statistics and structural equation modelling (SEM).

Emotional intelligence (EI) was proven to be a predictor of engineers' employability, which, in turn, depends on three factors: personal strengths that increase employment potential, self-perceived employment opportunities, and career development as a realization of employment potential.

These results show that the higher education system should implement activities to develop students' EI competencies, thus providing them with powerful tools to deal with different situations in the labour market.

The purpose of this study is to understand the influence of the transformational, transactional and laissez-faire leadership styles and collaborative integrative behavior of the team with respect to organizational ambidexterity (the combination of exploration and exploitation learning) in university research groups.

From a survey conducted with a sample of 506 researchers, members of 165 research groups, working in an emerging economy, a multiple regression model analysis was performed.

Findings of this study provide evidence that the coordinator's transformational leadership and the collaborative integrative behavior of the team positively influence organizational ambidexterity of research groups. Transactional leadership and laissez-faire style do not show any significant influence.

This study addresses the lack of knowledge regarding organizational learning in research groups to explore and exploit knowledge through research result transfer processes based on the organizational ambidexterity logic in higher education institutions (HEIs) from emerging economies. The study aims to contribute to the literature on leadership styles and ambidexterity in HEIs in emerging economies, particularly in Latin America, where there is still a scarcity of research on the attributes of effective leadership.

This study examines the role of universities in the social entrepreneurship ecosystems (SEEs) in Latin America from the perspective of female academic staff, administrators and outreach workers of universities in the region.

Using a qualitative approach, the study scrutinises in-depth interviews conducted with 24 women from eight Latin American universities.

The findings underscore the pivotal role of universities in promoting social entrepreneurship through knowledge generation, entrepreneur training, network enhancement and the promotion of equity. They also highlight the importance of incorporating a gender perspective into university programmes and practices.

The qualitative nature and small, diverse sample of this research inherently limit its scope. However, these limitations arise from the exploratory approach adopted, which was confined to eight Latin American countries. Further comparative studies in different contexts are needed to deepen the understanding of the dynamics involved.

Universities should offer more tangible support and training in social entrepreneurship with a gender focus. Governments can create incentives for universities to prioritise their contribution in this area.

The study emphasises the potential of women-led social entrepreneurship initiatives to generate positive impact, underscoring the need for inclusive supportive environments.

By providing insights on the role of Latin American universities in SEEs from a gender perspective, this study contributes to limited literature on the intersection of social entrepreneurship, gender, higher education and geographic context in the region. The research underscores the need to further explore how gender and regional dynamics influence social entrepreneurial ecosystems.

This paper aims to analyze how psychosocial support influences caring activities toward indigenous older adults.

A descriptive study with the participation of 229 informal indigenous caregivers. The study considered both sociodemographic and medical variables. It used the mini-mental test to determine the cognitive level in the elderly. It applied the Yesavage and Zarit scales to establish depressive symptomatology and caregiver burden. Finally, the study used the MOS psychosocial support and Apgar screening questionnaires to assess the psychosocial dimension and the patient’s family functional state, respectively.

The study observed a low caregiver burden effect using the MOS questionnaire. This may be explained due to variability in the Zarit Scale Score product of other variables like years of care (−0.17 and −0.28), depressive symptoms (0.16 and 0.18), cognitive level (mini-mental) (−0.13 and −0.14) and comorbidity (0.26 and −0.27). The study obtained an incidence between (−0.02 and −0.12) when including all assessed dimensions into the model. The instrumental dimension in the social support questionnaire obtained the highest score.

Protective factors prevail in the group of indigenous caregivers allowing this activity to not trigger overload. Yet, variables such as the female gender, some comorbidities and the presence of depressive symptoms could be potential variables for dysfunction in this occupational role.

The purpose of this study is to test the effect of entrepreneurship education programs (EEPs) on the individual entrepreneurial orientation (IEO) by considering the innovativeness, proactiveness and risk-taking dimensions of undergraduate students and the role of these dimensions on the relationship between program inspiration (PI) and entrepreneurial intention (EI).

This study uses a pre- and post-test analysis with data from 1,423 undergraduate students from two emerging countries in Latin America: Colombia and Ecuador. To verify the effect of the EEP on innovativeness, proactiveness and risk-taking at two-time points, the analysis of median for the difference of two paired populations (Sign Test and the Wilcoxon signed-rank test) was used. In addition, structural equation modeling analysis under the covariance and multigroup approach was applied to test the relationship between PI, IEO and EI.

The results of this study show that the EEP enhances innovativeness, proactiveness and risk-taking whose effects are more prominent in Ecuadorian students. Equally importantly, the EEP benefits represented in PI translate into higher EI through the mediating effect of the IEO dimensions for both the Colombian and Ecuadorian contexts, where the findings suggest no significant differences between two groups.

The findings of this study contribute to a better understanding of entrepreneurship education's role in entrepreneurial competence's development and intention by revealing the role of IEO dimensions. This study is one of the first studies that applies the IEO to contribute to the literature on the relationship between entrepreneurship education and intention from an emotional entrepreneurial perspective.

This study aims to analyse the consistency between what companies say (talk) and what they do (walk) regarding the application of double materiality in their sustainability reports.

Sustainability reports of 76 European companies that reported the application of double materiality and are listed in the Dow Jones Sustainability Index were studied through content analysis.

In total, 67% of the companies studied claim to apply double materiality but do not comply with the guidelines in this respect proposed by the European Financial Reporting Advisory Group. Therefore, these companies should be considered label adopters.

This study presents evidence of the existence of label adopters when double materiality is adopted at an early stage, meaning that regulators should seek to control compliance with the minimum requirements established for double materiality. This finding also has implications for assurers, who should consider the degree of real compliance with double materiality requirements when expressing their opinion.

The existence of label adopters in the application of double materiality endangers the sustainable development pursued through agreements such as the Green Deal and through the Sustainable Finance policy proposed in Europe.

This work contributes to the emerging literature on double materiality. Unlike previous works, empirical evidence is provided on the changes that companies present in their material issues with the application of double materiality. Moreover, it confirms the existence of label adopters in the application of double materiality.

The purpose of this paper is to determine the impact of private and public initiatives (financial literacy, entrepreneurship, remote work and government aid) on individual job loss and decrease in income during the COVID-19 pandemic in Peru.

The authors used an unbalanced panel data analysis with the National Household Survey for 2019–2020. The hypotheses are tested with a probit panel data model since the dependent variables are binary.

The study findings indicate that financial preparedness reduced the probability of having a decrease in income, but only to informal workers in metropolitan Lima. Furthermore, entrepreneurship helped mainly female informal workers to reduce their probability of becoming unemployed in metropolitan Lima. Besides, the implementation of remote work as a substitute of face-to-face work was not enough to avoid the decrease in income in the case of informal workers and it was only effective to avoid unemployment in the case of formal workers in metropolitan Lima. Finally, public aid proved to be instrumental in mitigating the decrease in income, but only to informal workers in Metropolitan Lima.

The study results only apply for the first year of the pandemic.

Policymakers should focus on increasing the financial preparedness of informal workers, especially in provinces.

Policymakers must expand unemployment benefits, and design public aid programs targeting informal workers in provinces.

This is the first study that analyses the impact of private and public initiatives on the decrease in income and unemployment situation of Peruvian individuals during the outbreak of the COVID-19 pandemic.
