Abstract

Purpose

The study aims to analyze the effect of the previous preparation and the work carried out in the field during a study trip on the development of competencies in agribusiness students.

Design/methodology/approach

The destination was the pineapple area of the Papaloapan Lower Basin in Mexico, and 42 students from 6 different semester levels participated. The students answered a test prior to the trip, received an evaluation for their activities in the field and prepared reports and posters as products of the experience. The relationship between the scores obtained was examined through a comparative analysis.

Findings

The findings are framed in the cyclical model of experiential learning with four stages (feeling, watching, thinking and doing) by Kolb (1984). It is found that the acquisition of specific knowledge about what the experience will entail leads to better preparation, motivation and confidence to live the experience (potentiation of feeling and watching). In turn, specific knowledge and better use of experience promote the development of problem solving, interpersonal and communication skills (potentiation of thinking and doing).

Research limitations/implications

Statistical representativeness is not a quality of the study since it is based on a comparative analysis.

Originality/value

The study analyzes an educational component of great value in the business area, about which little is known in the agribusiness subarea.

Abstract

Purpose

This research examines whether mentoring is a predictor of entrepreneurial intentions. It also explores how intent translates into action through implementation intentions. The study tests if the mentoring-intentions association is mediated by self-efficacy. The potential moderating effect of achievement motivation on the relationship was also investigated.

Design/methodology/approach

PLS-SEM was used to test the hypotheses of the 242 valid responses collected from final-year students from Libyan public universities.

Findings

Results show that self-efficacy partially mediated the mentoring-intentions association, while motivation negatively moderated the relationship. Entrepreneurial intentions had a significantly strong effect on implementation intentions.

Research limitations/implications

The results verify mentoring as a practical socializing instructional approach. Therefore, universities should implement structured mentoring programs, offering emotional guidance, counsel and networking opportunities. Also, mentors should undergo training, and progress tracking is essential for improvement.

Originality/value

Examining entrepreneurial self-efficacy as a mediator and achievement motivation as a moderator in the mentoring-intentions association is unprecedented. The findings narrow the search for antecedents to entrepreneurial intentions and pinpoint intervention points.

Abstract

Purpose

As research emerged in terms of how narcissism, a negative or dark trait, has been found to be constructive in enhancing entrepreneurial behaviour, there are mixed results regarding the significance of narcissism in the field of entrepreneurship. Additionally, this previous research has mostly been conducted on student or nascent entrepreneur samples within developed economies. Therefore, the purpose of this paper is to explore how narcissistic traits of established entrepreneurs in an emerging economy context infuence their entrepreneurial behaviour both positively and negatively.

Design/methodology/approach

Gioia methodology was applied in the qualitative study by means of in-depth interviews, which allowed for the unpacking of narcissistic traits among established entrepreneurs in South Africa. Four themes emerged from the data, and included insights related to entrepreneurial experience influencing behaviour; business growth linked to personal development; opportunity identification versus loss; and identity separation in relation to authentic identity versus an entrepreneurial identity.

Findings

The findings of the paper contribute to creating an understanding of how to hone individual narcissistic traits for positive influences that develop entrepreneurs while also contributing to their business development, opportunity realization and identity. In addition, the findings highlighted a separation between established entrepreneurs’ authentic personality and the inputs that end up resulting in the entrepreneurial personality.

Originality/value

This paper highlights the possibility of narcissism functioning as a business process involved in entrepreneurship rather than a necessary personality trait. An interesting dynamic contributed to what seems to be a constant battle between the authentic identity and the entrepreneur identity, gaining deeper insight surrounding established entrepreneurs’ experiences to survive and, more importantly, thrive as entrepreneurs.

Abstract

Purpose

Entrepreneurial support programs, like incubators and accelerators, often offer mentorship to new ventures. However, existing research on mentoring has mainly focused on the entrepreneur's perspective, leaving researchers with limited understanding of why experienced mentors provide support to new ventures. This study aimed to explore mentors' motives in mentor–venture relationships and their impact on the advisory process. It also examined different types of mentors (social and commercial) and their motivations for assisting and supporting new ventures.

Design/methodology/approach

The present study utilizes a qualitative research approach to investigate the motivations and mechanisms through which new venture mentors assist founders in their growth and success. In-depth interviews were conducted with 18 mentors supporting both social and commercial ventures. These mentors were selected from ten accelerator and incubator programs situated in Belgium. The interviews aimed to gain insights into the mentors' motivations and their experiences in the role of mentors.

Findings

Based on the social exchange theory and the norm of reciprocity, this study identified two main motives of mentors: “gaining back” reflecting mentors’ self-interest in deriving benefits from the relationship and “paying back” representing their altruistic reasons for supporting new ventures. Additionally, the study identified mentor functions that primarily involved providing career-related support to new ventures. Moreover, the research revealed intriguing similarities and differences in the motivations and mentoring functions between mentors of social and commercial ventures.

Research limitations/implications

Future research should explore the evaluation process and criteria used by mentors and new ventures when selecting each other for a productive mentoring relationship. Additionally, further investigation is needed to examine the firm-level impact of various mentoring services on the performance of social and commercial new ventures at different stages of development. Comparing mentor motives and functions across diverse geographical settings would address the limitation of the study and provide a more comprehensive understanding of the topic.

Practical implications

The findings of the study can inform policymakers, accelerator and incubator program managers and new ventures seeking mentors and support initiatives. They can use the insights to design effective mentoring programs that align with the specific needs and motivations of mentors and new ventures. Understanding the different motives and functions of mentors can help in the selection of appropriate mentors who can provide the necessary support and expertise to new ventures.

Social implications

The study highlights the importance of mentorship in the development of entrepreneurial ecosystems. Accelerator and incubator programs play a crucial role in connecting new ventures with mentors who have the right motivation and expertise, contributing to the growth and success of new ventures and the overall entrepreneurial ecosystem. By identifying both altruistic and self-interest motivations in mentoring relationships, the study emphasizes the dual dimensions that characterize the mentor–venture relationship. This understanding can foster stronger collaborations and reciprocal exchanges between mentors and new ventures, ultimately benefiting both parties.

Originality/value

This research contributes to the entrepreneurship literature by exploring the mentor–new venture relationship from mentors' perspective. It expands the existing research on mentor–protégé relationships, broadening the understanding of mentoring dynamics in different organizational settings. The findings offer insights grounded in social exchange theory and provide directions for future research on mentor–venture relationships, resource exchange and relationship development. The study also holds practical implications for policymakers and program managers involved in fostering mentoring initiatives for new ventures.

Abstract

Purpose

This study aims to investigate the morphing concepts able to manipulate the dynamics of the downstream unsteadiness in the separated shear layers and, in the wake, be able to modify the upstream shock–boundary layer interaction (SBLI) around an A320 morphing prototype to control these instabilities, with emphasis to the attenuation or even suppression of the transonic buffet. The modification of the aerodynamic performances according to a large parametric study carried out at Reynolds number of 4.5 × 106, Mach number of 0.78 and various angles of attack in the range of (0, 2.4)° according to two morphing concepts (travelling waves and trailing edge vibration) are discussed, and the final benefits in aerodynamic performance increase are evaluated.

Design/methodology/approach

This article examines through high fidelity (Hi-Fi) numerical simulation the effects of the trailing edge (TE) actuation and of travelling waves along a specific area of the suction side starting from practically the most downstream position of the shock wave motion according to the buffet and extending up to nearly the TE. The present paper studies through spectral analysis the coherent structures development in the near wake and the comparison of the aerodynamic forces to the non-actuated case. Thus, the physical mechanisms of the morphing leading to the increase of the lift-to-drag ratio and the drag and noise sources reduction are identified.

Findings

This study investigates the influence of shear-layer and near-wake vortices on the SBLI around an A320 aerofoil and attenuation of the related instabilities thanks to novel morphing: travelling waves generated along the suction side and trailing-edge vibration. A drag reduction of 14% and a lift-to-drag increase in the order of 8% are obtained. The morphing has shown a lift increase in the range of (1.8, 2.5)% for angle of attack of 1.8° and 2.4°, where a significant lift increase of 7.7% is obtained for the angle of incidence of 0° with a drag reduction of 3.66% yielding an aerodynamic efficiency of 11.8%.

Originality/value

This paper presents results of morphing A320 aerofoil, with a chord of 70cm and subjected to two actuation kinds, original in the state of the art at M = 0.78 and Re = 4.5 million. These Hi-Fi simulations are rather rare; a majority of existing ones concern smaller dimensions. This study showed for the first time a modified buffet mode, displaying periodic high-lift “plateaus” interspersed by shorter lift-decrease intervals. Through trailing-edge vibration, this pattern is modified towards a sinusoidal-like buffet, with a considerable amplitude decrease. Lock-in of buffet frequency to the actuation is obtained, leading to this amplitude reduction and a drastic aerodynamic performance increase.

Abstract

Purpose

This study explores the value of sports films for engaging youth in issues related to patriotism, justice, equity and liberty. The authors analyze how two sports films, 42 and Battle of the Sexes, have pedagogical potential and value in secondary social studies methods classes, as well as what criteria educators might use when selecting films (and television series) for classroom use.

Design/methodology/approach

Using content analysis, the authors respond to the following questions: (1) What critical themes related to civic education surface in the sports films 42 and Battle of the Sexes? and (2) What framework might guide the use of selecting sports films and sports film clips for educators' civic educational use?

Findings

Five themes surfaced in the films 42 and Battle of the Sexes: economics as a force for social change; racism and anti-Blackness, athletes as more than athletes, resisting oppression, and sexism and homophobia. Instruction related to these themes has the potential to engage students in critical, awareness-based approaches to civic education.

Originality/value

Sports films show promise for engaging youth due to their interests in the medium of film and in sports, both as participants and spectators. Across the world, athletes face questions and issues related to patriotism, justice, equity and liberty on courts, fields, tracks and rinks, These questions and issues are deeply embedded in civic education. This study is among the first of its kind to explore the pedagogical potential of sports films.

Abstract

Purpose

This paper aims to fulfil a need to identify assembly interfaces from existing products based on their Assembly Process Planning (APP). It proposes a tool to identify assembly interfaces responsible for reused components integration. It is integrated into a design for mixed model final assembly line approach by focusing on the identification of assembly interfaces as a generic tool. It aims to answer the problem of interfaces’ identification from the APP.

Design/methodology/approach

A tool is developed to identify assembly interfaces responsible for reused component integration. It is based on the use of a rule-based algorithm that analyses an APP and then submits the results to prohibition lists to check their relevance. The tool is then tested using a case study. Finally, the resulting list is subjected to a visual validation step to validate whether the identified interface is a real interface.

Findings

The results of this study are a tool named ICARRE which identify assembly interfaces using three steps. The tool has been validated by a case study from the helicopter industry.

Research limitations/implications

As some interfaces are not contained in the same assembly operations and therefore, may not have been identified by the rule-based algorithm. More research should be done by testing and improving the algorithm with other case studies.

Practical implications

The paper includes implications for new product development teams to address the difficulties of integrating reused components into different products.

Originality/value

This paper presents a tool for identifying interfaces when sources of knowledge do not allow the use of current methods.

Abstract

Purpose

The purpose of the paper is to analyse the performances of closures and compressibility corrections classically used in turbulence models when applied to highly-compressible turbulent boundary layers (TBLs) over flat plates.

Design/methodology/approach

A direct numerical simulation (DNS) database of TBLs, covering a wide range of thermodynamic conditions, is presented and exploited to perform a priori analyses of classical and recent closures for turbulent models. The results are systematically compared to the “exact” terms computed from DNS.

Findings

The few compressibility corrections available in the literature are not found to capture DNS data much better than the uncorrected original models, especially at the highest Mach numbers. Turbulent mass and heat fluxes are shown not to follow the classical gradient diffusion model, which was shown instead to provide acceptable results for modelling the vibrational turbulent heat flux.

Originality/value

The main originality of the present paper resides in the DNS database on which the a priori tests are conducted. The database contains some high-enthalpy simulations at large Mach numbers, allowing to test the performances of the turbulence models in the presence of both chemical dissociation and vibrational relaxation processes.

Abstract

Purpose

Entrepreneurship can help tackle economic problems, such as unemployment. It is often promoted through education programs. There is a limited comprehensive and rigorous understanding of how entrepreneurship education programs and their ubiquitous distance delivery affect young people's entrepreneurial self-efficacy and intention, particularly in non-formal settings. The purpose of this study is to address this gap.

Design/methodology/approach

Underpinned by the Social Cognitive Theory, this paper investigates the effects of one entrepreneurship education program in a study with 145 young people from five countries aged 18 to 25 years, 62 Intervention and 83 Control participants. The program's impact on the participants' entrepreneurial intention and self-efficacy (across six sub-dimensions) was assessed in a one-off two-week quasi-experiment. Ex-ante and ex-post self-reported data were collected about the participants.

Findings

One-way analyses of covariance were performed to assess separately for changes in the Intervention participants' answers, relative to the Control group. The results of this study suggest the program significantly affected all measures.

Originality/value

These findings contribute to the discussions on the education programs’ effectiveness in promoting entrepreneurship. As a result, they may contribute to entrepreneurship education overcoming geographical and socio-economic hurdles (cost, time and entry barriers) to advance the development of industry, economy and community worldwide.

Abstract

Purpose

This research adopts the social cognitive career theory (SCCT) and a moderated mediation model to investigate the moderating impacts of entrepreneurial fear of failure (FOF) and gender on the direct and mediation relationships between entrepreneurial education (EE), entrepreneurial self-efficacy (ESE) and entrepreneurial intention (EI).

Design/methodology/approach

The authors utilized a three-phase random sampling to compile a dataset from 1,890 graduate students from nine universities and higher education institutions in Vietnam. Cronbach's alpha and confirmatory factor analysis results showed that the key study variables were reliable and valid. Harman's single-factor method and other tests of analysis assumptions ruled out common method bias and other confounding factors. The authors utilized the PROCESS macro to test a hypothesized moderated mediation model that included direct, indirect and conditional indirect effects.

Findings

The findings yield that ESE partially and positively mediates the relation between EE and EI. FOF was found to negatively moderate the impacts of EE on ESE and EI, and the direct effect of ESE on EI among females is stronger than among males. More importantly, the mediation influence of FOF on the linkage between EE and EI becomes weaker when the level of FOF is high, yet this mediation relationship among females is higher than among males at all levels of FOF.

Practical implications

The results of this research are valuable for educators, policymakers and practitioners so that they may inspire individuals' entrepreneurial pursuits, especially those of female entrepreneurs.

Originality/value

This study significantly contributes to the entrepreneurship and gender literature by applying the SCCT to elucidate the moderated mediation impacts of FOF, ESE and gender on the relationship between EE and EI.
