Unlocking circular potential: The influence of personality traits on university students’ circular entrepreneurial attitude and intention
No full textConverting the paradigm of linear production into circular production is an enormous challenge whose implementation requires the intervention and collaboration of all the actors that make up the ecosystem. In this context, university students are privileged actors, as they may become future entrepreneurs responsible for promoting sustainable development. This research explores the effect of university students’ attitudes toward circular entrepreneurship on their intention to become a circular entrepreneur and the direct and indirect effects of three personality traits – perceived creativity, proactive personality, and risk-taking propensity – on both their circular entrepreneur attitudes and intentions, respectively. A quantitative approach was followed through the partial least squares method applied to a sample of 510 Portuguese university students. The results show that even though respondents reveal only a moderate intention to become circular entrepreneurs, this intention is directly influenced by their attitude toward sustainable entrepreneurship and indirectly (in this order) by their propensity to take risks, having a proactive personality, and creativity. The attitude toward sustainable entrepreneurship is, in turn, positively influenced by respondents’ propensity to take risks and their proactivity without any effect of creativity. The present study demonstrates the importance of younger personality traits on their attitudes regarding sustainability business and their intentions to become circular entrepreneurs. The present study shows that students’ risk-taking and proactive personality and, in particular, their creativity should be stimulated to create a new generation of circular entrepreneurs. With this work, we seek to help develop a new class of entrepreneurs, praising the role of universities, which allows Portugal to be closer to achieving sustainable development. Furthermore, this study will contribute to the yet scarce literature about circular economy and entrepreneurship in general
Homo Sapiens Entrepreneurensis: The Base Business Creation Model
Get PDFThis book allows anyone to understand an entrepreneur's main characteristics and challenges and what is to be market-oriented. Why do we often complain about the providers of the products we need and the products themselves? Based on a theoretically sound background, the Base Business Creation Model is presented, which helps to test any business idea in all diverse contexts, private or public, for-profit or not-for-profit, even within a company, as a manifestation of intrapreneurship. This model includes the assessment of economic and financial viabilities, contributing to diminishing the probability of failure, which is relatively high among start-ups. Step-by-step, the entrepreneurs learn how to test their concepts of the product (good, service, idea, experience, behaviour, information), aiming at satisfy human and social needs, passing through the evaluation of the business opportunity, the design of a business model, and the assessment of its financial viability. Then, if the business concept has a reasonable probability of success, the entrepreneur can prepare a complete business plan using the Advanced Business Creation Model

Core Organizational Societal Impact (COSI): An evolving model
No full textMeasuring the social impact of organizations is complex and challenging, and it cannot be generalized to all cases. This conceptual study aims to theoretically substantiate a flexible measure of societal impact and provide recommendations to improve the accuracy and validity of such measures. The Core Organizational Societal Impact (COSI) measure is based on stakeholder, corporate social responsibility, and societal sustainability theories, assessing any organization’s societal impact, comprising indicators of general application and discretionary ones. This model can be used as a proxy and acid test to measure organizational societal footprint, i.e., how organizations impact the stakeholders based on their economic, social, legal, ethical, ecological, psychological, and discretionary responsibilities. It constitutes an adjustable index that allows for assessing the organization’s evolution and comparisons with other organizations in the activity sector. This approach sensitizes managers and entrepreneurs in any activity sector to choose a marketing strategy with a positive societal impact
Omega-3 polyunsaturated fatty acids in children with Attention Deficit Hyperactivity Disorder: A systematic review
No full textAbstract
Introduction: Attention Deficit-Hyperactivity Disorder (ADHD) is a neurodevelopmental disorder that affects a significant population of children. Omega-3 supplementation is being explored since standard pharmacological treatments cause bothersome side effects. Our objective is to examine the impact of Omega-3 fatty acids on the symptoms of ADHD in children.
Methods: We conducted a systematic review, searching for randomized clinical trials in MEDLINE, Embase, and Web of Science from April 17th until May 1st, 2024. Studies were included if they involved children aged 6–18 with ADHD who consumed Omega-3 fatty acids through diet or supplementation. Studies were excluded if they included individuals without an ADHD diagnosis, used animal models, or supplements alongside Omega-3. Data extraction and Cochrane Risk-of-Bias (RoB2-tool) analysis were performed using Covidence. Findings were described in tables and analyzed.
Results: A total of thirty-one eligible randomized clinical trials were included, evaluating 2,494 individuals with an average age of 8.93 years (SD = 1.39). Most studies (90.3%) followed a two-arm design comparing Omega-3 supplementation to placebo. While fourteen studies (45.1%) reported statistically significant benefits of Omega-3 supplementation in overall ADHD symptoms, the sub-analysis on hyperactivity/impulsivity and inattention symptoms showed no significant effects or differences between groups. Studies were highly heterogeneous in design, interventions, trial duration, dosage, and outcome measurement tools.
Conclusion: Overall, Omega-3 may not have a significant effect on ADHD symptoms to recommend its use. Future research should address the limitations, such as the main dose and comparator and also ideal treatment time
Self-compassion around the World: Measurement invariance of the short form of the Self-Compassion Scale (SCS-SF) across 65 nations, 40 languages, gender identities, and age groups
No full textThe 12-item Self-Compassion Scale–Short Form (SCS–SF) is a widely used instrument for the assessment of self-compassion. To date, there have been few examinations of this instrument’s psychometric properties, particularly across nations and languages. Therefore, we used data from the Body Image in Nature Survey (BINS) to assess measurement invariance of the SCS–SF across nations, languages, gender identities, and age groups.
Participants (N = 56,968) from 65 nations completed the SCS–SF in 40 languages. Using these data, we tested various hypothesised models of the SCS–SF in the total sample and, using multi-group confirmatory factor analysis, tested for invariance of the optimal model across national groups, languages, gender identities, and age groups.
In the total dataset, we found that an 11-item, 2-factor model (i.e., SCS-11) provided best fit to the data, with the two factors tapping distinct constructs of compassionate and uncompassionate self-responding. The SCS-11 was found to be partially scalar invariant across national groups and languages, and fully scalar invariant across gender identities and age groups. There was wide variation in latent means for the two factors, particularly across national groups and languages. Further analyses showed negligible associations between the two factors and sociodemographic variables, including marital status, financial security, and urbanicity.
Our results suggest that it may be possible to derive a stable 2-factor model of the SCS–SF for use in cross-cultural research, but also highlight the likelihood of cross-national and cross-linguistic variations in the way that self-compassion is understood

Between virtual and in-person: Academic decision-making in the Era of hybrid event
No full textScientific events play a fundamental role in academic and professional tourism, allowing for the dissemination of knowledge, networking and experiences exchange between experts from different fields. With the advance of technology, online events have gained ground, especially after the Covid-19 pandemic, raising questions about whether face-to-face events can be definitively replaced. This study aims to identify the participants' preferences to attend physical and/or online scientific events, exploring trends, challenges and preferences in holding these meetings. The empirical study is based on an interview script applied to 22 tourism university professors and researchers, exploring trends, challenges and preferences in holding these meetings. The results indicate that the respondents recognize a sum of advantages as well as disadvantages in both formats –physical and online.Although online events have become a viable and advantageous alternative in many respects, face-to-face events remain essential for networking building deeper connections and enriching experiences. However, the choice of destination will continue to be a relevant factor for physical events, influencing participants' decisions based on infrastructure, cultural attractions and cost-effectiveness.The future of scientific events will probably be marked by a hybrid approach, balancing the best of both formats.This study provides theoretical and practical contributions to the Meetings Industry (MI) sector. These trends indicate that organisers of scientific events need to adapt their formats to meet the new demands of participants, guaranteeing valuable and accessible experiences for the global academic and professional community
Generation Z and Travel Motivations: The Impact of Age, Gender, and Residence
No full textThis study investigates the relationship between demographic factors and travel motivations among Generation Z leisure tourists through the lens of the Travel Career Pattern (TCP) theory. More specifically, the research focuses on how gender, age, and area of residence influence the travel motivations of Generation Z. Using a quantitative approach, data were collected from 303 respondents aged 18 to 28 through an online survey. The questionnaire assessed 14 motivational factors and analyzed them in relation to the participants’ demographic characteristics using linear regression models. Results indicate that gender and age significantly influence travel motivations, with women showing higher interest in personal development and social relationships, while men prioritize nature and adventure. Furthermore, rural residents exhibit greater motivation for autonomy, self-development and self-realization, while urban residents lean towards novelty and social interactions. The findings offer valuable insights for tourism marketers, emphasizing the importance of creating segmented marketing campaigns based on demographic factors. It also contributed to overcoming the lack of studies that specifically cover this interrelation between the motivational factors of Generation Z and the demographic factors of age, gender and area of residence. Nevertheless, this study also has limitations, such as the use of a non-representative sample and the focus on quantitative methods, suggesting that future research should adopt qualitative approaches and examine additional demographic variables to gain deeper insights into youth travel motivations
Analysis of factors influencing the academic conference participation
No full textThis article aims to explore the main factors that influence academics’ decision to participate in academic and scientific events. A quantitative methodology is developed by applying online questionnaires to academics who regularly participate in scientific events. Results show that the factors that tend to influence the decision to participate in scientific events can be grouped into four types: organizational context, academic opportunities, opportunities for leisure, recreation, and culture, and event accessibility. The originality of this work lies in the updated identification and consideration of recent events related to the COVID-19 pandemic, as well as the main factors influencing the decision of choice related to the scientific events in which academics participate
