Abstract
Purpose
This study aims to shed light on the lack of understanding and previous mixed results regarding why and how some internationalised firms take advantage of host-home country similarity (HHS) while others do not.
Design/methodology/approach
Direct and mediating hypotheses are examined through an empirical investigation of 156 CEOs in internationalised Spanish companies, using structural equation modelling validated by factor analysis.
Findings
The results suggest that exploitation (EI) and exploration (ER) constitute important learning mechanisms that impact on the liability of foreignness when internationalising a business. In particular, the positive influence that HHS has in international firm performance (IP) depends on both exploitative and exploratory learning.
Practical implications
This research adds insights into the importance of two of the main components of organisational learning (i.e. ER and EI) as mediators of the HHS and IP relationship, which can help senior managers or business owners make consistent decisions by matching potential international market locations with firm learning factors.
Originality/value
This study clarifies contradictory theoretical assertions and mixed empirical results about how HHS impacts on international performance. In particular, by responding to recent calls for research, this study has shown that organisational learning is a key component in the aforementioned link where ER and EI positively mediate this relevant relationship.

Abstract
Purpose
The purpose of this paper is to present a novel control mechanism for avoiding overlapping among biclusters in expression data.
Design/methodology/approach
Biclustering is a technique used in analysis of microarray data. One of the most popular biclustering algorithms is introduced by Cheng and Church (2000) (Ch&Ch). Even if this heuristic is successful at finding interesting biclusters, it presents several drawbacks. The main shortcoming is that it introduces random values in the expression matrix to control the overlapping. The overlapping control method presented in this paper is based on a matrix of weights, that is used to estimate the overlapping of a bicluster with already found ones. In this way, the algorithm is always working on real data and so the biclusters it discovers contain only original data.
Findings
The paper shows that the original algorithm wrongly estimates the quality of the biclusters after some iterations, due to random values that it introduces. The empirical results show that the proposed approach is effective in order to improve the heuristic. It is also important to highlight that many interesting biclusters found by using our approach would have not been obtained using the original algorithm.
Originality/value
The original algorithm proposed by Ch&Ch is one of the most successful algorithms for discovering biclusters in microarray data. However, it presents some limitations, the most relevant being the substitution phase adopted in order to avoid overlapping among biclusters. The modified version of the algorithm proposed in this paper improves the original one, as proven in the experimentation.

Abstract
Purpose
The purpose of this paper is to establish a readiness for entrepreneurship theoretical framework. The paper marks the first of three stages to build a scale to measure readiness for entrepreneurship.
Design/methodology/approach
The current paper is conceptual. The research approach consists of formulating proposals and definitions based on an extensive literature review.
Findings
The literature review reveals that no such readiness for entrepreneurship measurement tool exists. The literature review also yields definitions and components of key concepts for the theoretical framework.
Research limitations/implications
The paper offers a new, holistic perspective of readiness for entrepreneurship. This research addresses measurement of readiness for entrepreneurship from a rigorous, scientific approach. The main limitation lies in capturing and organizing extensive information on topics from diverse disciplines (i.e. sociology, psychology, and business management).
Practical implications
This theoretical framework enables the design and creation of a scale to measure readiness for entrepreneurship. The literature review confirmed the possibility of building such a measurement scale.
Social implications
A complex tool able to identify and measure readiness for entrepreneurship would be applicable in numerous situations including the following: determining entrepreneurial abilities, analyzing potential for entrepreneurship, simulating organizational transformations, and evaluating investment recommendations.
Originality/value
No holistic, scientifically grounded tool to measure readiness for entrepreneurship exists, yet there are numerous entrepreneurial capacity tests with no rigorous scientific grounding. As a remedy, this paper provides solid scientific foundations upon which to develop an instrument for measuring readiness for entrepreneurship.

Abstract
Purpose
In education concerning environmental issues, there are two predominant currents in the world, environmental education (EE) and education for sustainable development (ESD). ESD is the formal commitment and therefore promoted by the United Nations, to ensure that countries achieve sustainable development. In contrast, EE was the first educational trend with an environmental protection approach. The purpose of this systematic review that seeks to show whether the migration from EE to ESD is being effective and welcomed by researchers and especially by universities is presented. With the above, a global panorama can be provided, where the regions that choose each model can be identified. In the same sense, it was sought to determine which of the two currents is more accepted within engineering education.
Design/methodology/approach
The review followed the preferred reporting items for systematic reviews and meta-analyzes parameters for systematic reviews. In total, 198 papers indexed in Scopus, Science Direct, ERIC and Scielo were analyzed. With the results, the advancement of ESD and the state of the EE by regions in the world were identified.
Findings
It was possible to categorize the geographical regions that host either of the two EE or ESD currents. It is important to note that ESD has gained more strength from the decade of ESD proposed by the United Nations Educational, Scientific and Cultural Organization. For its part, EE has greater historical roots in some regions of the planet. In turn, there is evidence of a limited number of publications on the design and revision of study plans in engineering.
Originality/value
Through this systematic literature review, the regions of the world that are clinging to EE and those that have taken the path of ESD could be distinguished. Moreover, specific cases in engineering where ESD has been involved were noted.

Abstract
Purpose
The purpose of this paper is to present a project called EmprendeSport, whose aim is to increase knowledge in entrepreneurship and sports in students, professors and professionals through seminars carried out from 2015 to 2018. This study summarises the experience and data extracted throughout these seminars with the purpose of helping to design policies that stimulate business activity of the universities that seek to promote entrepreneurial spirit within a higher educational context.
Design/methodology/approach
This is a descriptive paper of the experiences of the seminars done during four years, with a regularly assistance of 200 people. The profile of the assistants was, mainly males, studying a degree on sports or entrepreneurship and working.
Findings
There is a lack of knowledge and interest in entrepreneurship. The realisation of the seminar resulted to be a useful incentive for the public to develop new ideas to innovate in their daily lives, some of them also, because of the seminar through of creating their own business. From the organisation perspective, in order to increase the entrepreneurial culture between the females.
Originality/value
The main contribution of this document could be to help design policies that stimulate business activities of universities and, therefore, stimulate their contribution to the development of the modern knowledge economy.

Abstract
Purpose
The purpose of this paper is to understand the current relationship between factors such as desire and viability and entrepreneurial intention, using the Business Event Model as a point of analysis, as well as to understand the influence of gender as a moderating effect on entrepreneurial intention.
Design/methodology/approach
A total of 278 students from the Faculty of Education Sciences (University of Seville) were invited to participate with students carrying out degrees in Physical Activity and Sport Sciences.
Findings
There is a positive and similar relationship between desire and viability due to gender-related reasons. In the same way, this study presents a positive relationship in men and women, between desire and viability, desire and entrepreneurial intention and viability and entrepreneurial intention.
Practical implications
The public policies of the university should be oriented to the promotion of the desire perceived in women, carrying out sessions or training courses, where the speakers could be women leaders of companies. In addition, public policies should promote the perceived viability of men through training by providing technical resources on the operation of a company.
Social implications
This study provides theoretical knowledge on the entrepreneurial intentions of students at the University of Seville and therefore may help to improve policies aimed at promoting entrepreneurship.
Originality/value
This study provides clear practical implications for the management of students, and the findings facilitate the improvement of university policies designed to promote entrepreneurship in this type of student.

This study aims to present the climate change effect on soil moisture regimes in Mexico in a global 1.5°C warming scenario.
Abstract
Purpose
This study aims to present the climate change effect on soil moisture regimes in Mexico in a global 1.5°C warming scenario.
Design/methodology/approach
The soil moisture regimes were determined using the Newhall simulation model with the database of mean monthly precipitation and temperature at a scale of 1: 250,000 for the current scenario and with the climate change scenarios associated with a mean global temperature increase of 1.5°C, considering two Representative Concentration Pathways, 4.5 and 8.5 W/m2 and three general models of atmospheric circulation, namely, GFDL, HADGEM and MPI. The different vegetation types of the country were related to the soil moisture regimes for current conditions and for climate change.
Findings
According to the HADGEM and MPI models, almost the entire country is predicted to undergo a considerable increase in soil moisture deficit, and part of the areas of each moisture regime will shift to the next drier regime. The GFDL model also predicts this trend but at smaller proportions.
Originality/value
The changes in soil moisture at the regional scale that reveal the impacts of climate change and indicate where these changes will occur are important elements of the knowledge concerning the vulnerability of soils to climate change. New cartography is available in Mexico.

Abstract
This chapter examines the training of indigenous Mayan catechists by the Roman Catholic Diocese of San Cristóbal de Las Casas in Chiapas, Mexico, and their subsequent role in the establishment and growth of the Ejercito Zapatista de Liberación Nacional (EZLN) in the period prior to the Zapatistas' 1994 uprising. It considers the adequacy of Timothy Wickham-Crowley's model of guerrilla insurgencies in Latin America in explaining the Zapatista case. It finds, contrary to Wickham-Crowley's model of the relations between urban university leadership groups and peasant support bases, that the catechists constituted a stratum of “organic indigenous-campesino intellectuals” that radically undermined their communities’ traditional intellectual dependence on outsiders and enabled them to constitute themselves as a new collective political subject.
