This paper aims to propose and test a corporate entrepreneurship strategy (CES) model in small- and medium-sized enterprises (SMEs) with international activity located in Andalusia (Spain) – a peripheral region with high levels of inequality in the European Union (EU).

A quantitative analysis has been carried out with data from 101 SMEs to contrast and analyze the proposed CES model. The sample data were obtained through questionnaire-guided interviews with chief executive officers. Data processing has been done using partial least squares-path modeling, a variance-based technique for structural equation modeling.

The results of this study show the positive effect of environmental conditions on the development of CES actions in Andalusian SMEs (Spain) and the positive influence of CES on the results of SMEs’ international activity. In turn, environmental conditions do not directly affect the international activity.

Although previous works address the relationship between corporate entrepreneurship (CE) and international enterprise activity, to the best of the authors’ knowledge, this work is original in testing a CES model (including CE and the entrepreneurial strategic vision) in SMEs in a region that has one of the lowest levels of development in the EU. The results have important implications for SMEs and policymakers and could be extrapolated to other emerging economies.

The aim of this work is to evaluate the effectiveness of a training programme for developing employability skills, including digital competency and soft skills (problem-solving, teamwork, adaptability, leadership, decision-making and creativity), in professional-training programmes.

It presents a case study where students from a professional training centre were evaluated twice, before and after doing the programme. The results from both were compared to determine whether there have been improvements. We also analysed whether there were differences by gender in the pretest and the posttest.

We observed that most of the students improved in both digital competency and in soft skills after completing the programme. In the case of digital competency, greater improvement was apparent in the areas of collaboration and communication and in digital content creation. Similar results were found for all competencies in the case of soft skills.

This learning programme had a positive impact on the competency development of professional-training students. Continuous training and advice for teachers and personalized monitoring during the implementation of this programme resulted in an apparent improvement in students’ employability skills.

This paper aims to propose future public policy guidelines (FPPG) in sustainable regional development for Guaviare (Colombia) – a territory affected by environmental and social distress – for the year 2035.

Following collective action theory and sustainable regional development literature, a foresight exercise was conducted using site focus groups and semi-structured interviews with local participants to identify future strategic change drivers and the most relevant social actors for the attainment of economic, social and environmental development in the Guaviare through FPPG.

The findings suggest that the development of public policies regarding building consensus around Guaviare’s economic, environmental and social issues, reducing conflict between the region’s cultural and environmental ways, decreasing isolation from the centers of decision-making, increasing the transparency of public institutions and reducing insecurity to attract investments are all crucial to attaining sustainable regional development.

Interdisciplinarity is implicit in the local perspectives on the problem that impedes sustainable development in San José del Guaviare. The paper’s main contribution is the long-term vision that breaks away from the traditional short-termism in public policy guidelines in a Latin American context. Methodologically, the significant contribution is the convergent alignment of specific foresight methods toward public policy guidelines’ analysis and design processes.

The purpose of this paper is the design and experimental investigation of compact hybrid sound-absorbing materials presenting low-frequency and broadband sound absorption.

The hybrid materials combine microchannels and helical tubes. Microchannels provide broadband sound absorption in the middle frequency range. Helical tubes provide low-frequency absorption. Optimal configurations of microchannels are used and analytical equations are developed to guide the design of the helical tubes. Nine hybrid materials with 30 mm thickness are produced via additive manufacturing. They are combinations of one-, two- and four-layer microchannels and helical tubes with 110, 151 and 250 mm length. The sound absorption coefficient of the hybrid materials is measured using an impedance tube.

The type of microchannels (i.e. one, two or four layers), the number of rotations and the number of tubes are key parameters affecting the acoustic performance. For instance, in the 500 Hz octave band (α₅₀₀), sound absorption of a 30 mm thick hybrid material can reach 0.52 which is 5.7 times higher than the α₅₀₀ of a typical periodic porous material with the same thickness. Moreover, the broadband sound absorption for mid-frequencies is reasonably high with and α₁₀₀₀ > 0.7. The ratio of first absorption peak wavelength to structure thickness λ/T can reach 17, which is characteristic of deep-subwavelength behaviour.

The concept and experimental validation of a compact hybrid material combining a periodic porous structure such as microchannels and long helical tubes are original. The ability to increase low-frequency sound absorption at constant depth is an asset for applications where volume and weight are constraints.

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.

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.

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).

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

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