The commercialization of research produced by universities constitutes a core facet of academic entrepreneurship (AE). Academic literature reveals the need to shed light on entrepreneurial processes in higher education institutions (HEIs). This study intends to fill this gap by researching the mechanisms for facilitating AE and the variables that can moderate the relationship between such mechanisms and AE in Portuguese HEIs.

Our research model aims to assess the mechanisms of academic entrepreneurship (AE) within a sample of 125 Portuguese public higher education institutions (HEIs). To test our research hypotheses, we employed a structural equation model (SEM) using the partial least squares (PLS) method. Additionally, our evaluation examines the potential moderating effects of incubator programs, support initiatives, and proof-of-concept programs (PoCs). Our research model seeks to evaluate the mechanisms for facilitating AE and explore the effects of including incubator programs, support initiatives, and PoCs as moderators. The seven variables (Research mobilization, Unconventionality, Industry collaboration, University policies, Incubator programs and support initiatives, Proof-of-concept programs, and academic entrepreneurship) were measured using a 7-point Likert scale.

The results revealed that different drivers of AE influence the creation and development of entrepreneurial activities. Our findings also show the moderating effects of incubator programs, support initiatives, and proof-of-concept programs on AE. We find that incubator programs, other support initiatives, and PoCs maintain a moderating effect on AE and benefit their respective HEIs.

The study examines only the Portuguese HEI context. Therefore, generalizing these results necessitates reservations. However, the responses came from various actors in HEIs, from different academic backgrounds and research interests. This makes the results more generalizable. Limitations are evident in external validity, given that we gathered the data over a relatively short period.

Observed factors are explored to gain a deeper understanding of their influence on the mechanisms of AE. The implications arise from the new perspective presented and the methodology used to identify mechanisms capable of fostering AE. We hope this research will encourage other researchers to study this topic further.

the engagement of universities at the global level should be emphasised in future policy. While universities in innovation systems often have a local focus, their engagement in innovation ecosystems transcends the boundaries of geographic locations.

PoCs had a significant positive moderating effect on the impact of research mobilization and university policies on AE. Thus, we find interactions between universities and industry boost AE. This study demonstrates how AE benefits HEIs by extending orientation towards mobilizing research, unconventional approaches, cooperation with industry, and university policy implementation. We thus advocate a new approach, demonstrating the influence that the mobility of research, unconventionality, industry collaboration, and university policies hold over AE.

This paper examines the relationship between the adoption of accrual-based IPSAS and the level of perceived corruption of Latin-American countries, considering the moderating effect of the country’s institutional quality.

The study adopted a longitudinal analysis of 19 countries, between 2010 and 2020, following a quantitative approach by using multiple linear regression with panel data.

Main findings indicate that the harmonization of public sector accounting through the adoption of IPSAS generates a positive effect on the corruption level in Latin-American countries, causing a reduction in their indexes of perception of corruption. The countries’ institutional context, as hypothesized, increases such effect, making it even more significant in the cases of partial adoption.

To improve accountability and decision-making in public sector entities overall, contributing to reduce corruption, IPSAS adoption requires an institutional environment favorable to take the best of their benefits.

The adoption of IPSAS in an environment with a high institutional quality, allows a greater effect in reducing corruption in the jurisdiction.

This study contributes by providing a comprehensive view of IPSAS and its impact on perceived corruption levels, expanding the existing research to Latin America, where corruption is generally high and IPSAS may contribute to reduce it. It makes an important addition by defining and considering an index of the country’s institutional quality, providing evidence that when this is high, the context enhances the work of institutions, including IPSAS, to fight corruption.

This study aims to investigate the role of Industry 4.0 (I4.0) technologies (base and front-end) on the deployment of Lean bundles (just-in-time, total productive maintenance and total quality management) to achieve operational performance.

We adopt a stakeholder perspective by considering the role of leaders, employees and customers when engaged in quality improvement. The objective is to compare moderation and mediation models and address a gap in literature related to the contrasting outcomes from I4.0 technologies and Lean deployment on firm performance. We perform survey research involving 270 manufacturing firms. We use factor analysis, hierarchical ordinary least squares regression and bootstrapping techniques to evaluate the hypothesised relationships.

Our findings confirm I4.0’s mediating influence, suggesting that organisations focusing on stakeholders’ engagement in quality more effectively develop Lean bundles and achieve operational performance. Regarding moderation models, we find no significant relationship between base technologies (Internet of Things, big data, cloud computing and artificial intelligence) and contrasting results from front-end technologies (robotics, simulation, augmented and/or virtual reality and 3D printing) on deployment of Lean bundles.

Our work theoretically contributes to the current operations management field by showing that organisations should first engage stakeholders for quality improvement instead of trying to engage stakeholders and adopt digital technologies simultaneously to deploy Lean bundles.

This study aims to evaluate the effectiveness of machine learning models to yield profitability over the market benchmark, notably in periods of systemic instability, such as the ongoing war between Russia and Ukraine.

This study made computational experiments using support vector machine (SVM) classifiers to predict stock price movements for three financial markets and construct profitable trading strategies to subsidize investors’ decision-making.

On average, machine learning models outperformed the market benchmarks during the more volatile period of the Russia–Ukraine war, but not during the period before the conflict. Moreover, the hyperparameter combinations for which the profitability is superior were found to be highly sensitive to small variations during the model training process.

Investors should proceed with caution when applying machine learning models for stock price forecasting and trading recommendations, as their superior performance for volatile periods – in terms of generating abnormal gains over the market – was not observed for a period of relative stability in the economy.

This paper’s approach to search for financial strategies that succeed in outperforming the market provides empirical evidence about the effectiveness of state-of-the-art machine learning techniques before and after the conflict deflagration, which is of potential value for researchers in quantitative finance and market professionals who operate in the financial segment.

The purpose of this article is to analysis of the effects of green innovation ecosystem coopetition (cooperation and competition), environmental management practices (EMPs) and digital innovation (DI) on carbon footprint reduction.

To conduct the study, a questionnaire was administered to hotel managers from different regions of Brazil. Data were collected from 197 hotels and analyzed via partial least squares structural equation modeling.

The results show that green innovation ecosystem cooperation positively and significantly affects EMPs and DI. Green innovation ecosystem competition interactions also benefit the adoption of EMPs. However, they do not significantly influence the use of DI. The results indicate that hotels that are in a scenario of simultaneous competition and collaboration (coopetition) within the green innovation ecosystem can reduce carbon emissions when EMPs and DI are used.

The authors contribute to the literature by showing different pathways for reducing the carbon footprint of hotels. The results expand the authors’ knowledge by showing evidence that cooperation and competition interactions can produce distinct effects, especially on DI. Thus, this study has important practical implications for hotel managers seeking to improve their environmental practices and DI with the help of external multiagent resources and knowledge.

This research contributes to the literature by examining how cooperation and competition interactions in the green innovation ecosystem help in the adoption of environmental management and DI practices.

The study aims to understand what learning is evidenced regarding knowledge about the teaching of mathematics by five primary teachers when they reflect on research lessons. To do so, we used situations from the formal and informal reflection sessions that took place after teaching four research lessons.

It is a qualitative and interpretative research. Data collection was done by participant observation with elaboration of a research journal, audio recording of sessions and a whole-group interview. Data analysis was made by content analysis based on the conceptual framework.

The study shows the relevance of carrying out successive research lessons, followed by moments of formal and informal reflection, leading to improvements in relation to the way the task is proposed to the pupils, the representations used and the monitoring and questioning carried out by the teacher in the various phases of the lesson.

In lesson study, very often, only one research lesson is held. This case shows the potential of successive research lessons, each of which is followed by moments of reflection, in promoting the development of teachers’ didactic knowledge, namely regarding teaching practice, providing a more in-depth look at the way pupils work on mathematical tasks and the role of the teacher in promoting learning. Reteaching proved to be a valuable strategy to support teachers’ reflections in order to improve the leading of pupils’ work.

In the realm of innovation systems and technology transfer (TT), the emergence of open innovation and complex market dynamics has amplified innovation intermediaries’ prominence of their role and involvement in TT projects. This study delves into private consultants’ involvement in TT projects, namely in what got them involved by the project’s key stakeholders.

An iterative two-phased research approach was followed, including exploratory interviews and a quantitative case study of a consultancy firm engaged in 219 TT projects.

Five main key motivators were found to lead TT stakeholders to involve private consultants in their TT projects, being the most relevant, the proactivity of private consultants.

The case study and results provide an alternative perspective of TT endeavours, emphasising the importance given by TT stakeholders (mostly recipient companies) to private consultants’ involvement as innovation intermediaries.

This study aims to examine the role of edible mushrooms in the Brazilian diet, considering their strategic significance in meeting nutritional goals within sustainable development. Despite their potential in the nutrition of the Brazilian population, significant knowledge gaps still exist. To address this, the authors formulated this study into five main sections: the consumption of edible mushrooms in Brazil, the factors influencing the consumption, the occurrence of edible mushrooms in Brazil, the nutritional contribution of mushrooms consumed in Brazil and sustainable mushroom production in Brazil.

The authors compiled current literature to develop this viewpoint paper using systematic review, systematic search and narrative review search methods.

Mushrooms are sporadically consumed in Brazil, primarily by the urban population, with challenges in estimating the most used species. Social, economic and cultural factors, health considerations and reduced meat consumption influence mushroom consumption behavior. While Pleurotus ostreatus, Lentinula edodes and Agaricus bisporus are primary species, ethnomycological studies highlight a more diverse consumption among traditional indigenous communities. Brazil hosts approximately 133 wild mushroom species safe for human consumption. Some can be sustainably cultivated using substrates derived from agricultural and urban waste, offering high-protein, high-fiber, low-fat foods with bioactive compounds holding antioxidant and prebiotic potential.

To the best of the authors’ knowledge, no previous study has investigated how edible mushrooms contribute to the food and nutrition of the Brazilian population. This study emphasizes the crucial role of edible mushrooms in preserving Brazil’s cultural heritage, contributing to food and nutritional security and enhancing the overall diet quality.

Drawing on the resource-based view (RBV), this paper aims to analyse the relevance of Industry 4.0 (I4.0) technologies and participation in global value chains (GVC) and the effects of the complementarity between both in the adoption of circular economy (CE) actions by small and medium-sized enterprises (SME).

This paper analysed a large-scale international sample by employing logistic and linear regression models to test the research hypotheses on the effects of I4.0 technologies, GVC participation, and the interaction on CE actions (recycling or reusing materials, reducing the consumption and impact of natural resources, saving energy and/or switching to sustainable energy sources, developing sustainable products or services).

The evidence suggests that I4.0 technologies already represent important resources for CE adoption and SME participating in GVC display a greater likelihood of adopting CE actions. From the perspective of resource complementarity, by interacting the two factors viewed as resources in this article, results may report that adopting I4.0 technologies and simultaneously participating in GVC may turn out detrimental to SME undertaking CE actions, specifically as regards recycling and reusing materials, saving energy or switching to sustainable energy sources and in cases of widely adopting CE practices.

The paper returns novel insights into the adoption of CE practices by presenting evidence that I4.0 technologies and participation in GVC may be successful means for SME seeking to implement CE actions but must be combined carefully. This paper also provides theoretical and practical implications for SME managers, firms participating in GVCs and policy makers, and shedding light on new research avenues.

This paper aims to examine volunteer tourism (VT) experiences of three stakeholder groups in Rio de Janeiro, Brazil. The guiding research question is: how does VT influence marginalized communities from the perspectives of different stakeholders? This study was developed to address a need for further research that critically looks at the social impacts of VT in vulnerable communities and analyze the nature of VT by reviewing concepts related to sustainable tourism and social representation theory (SRT).

Using a phenomenological approach, this study is founded on SRT to understand the lived experiences of VT and the perceptions of its impacts on favela (slum) communities. This paper describes and interprets these meanings with a high degree of depth and richness using interviews, observation and document analysis. The experiences of community residents, voluntourists and non-governmental organization (NGO) staff are considered.

Study findings indicate that the different groups expressed several benefits and obstacles to VT. Voluntourists had a difficult time interpreting what influences VT has in general for the community focusing more inwardly on their personal experiences. Community residents experienced VT differently than the other groups. They identified the most benefits from VT and felt that they had the ability to create representations of themselves and of their community overall. NGOs expressed positive aspects of VT such as more community participation but noted concerns with voluntourists’ commitment.

This study is one of few to consider and compare the VT perceptions of three different stakeholder groups in vulnerable communities.
