A summary of the economic impact resulting from the celebration of a sporting mega-event in the city of Cali, Colombia, is carried out in this article.

The impacts are estimated by means of the systematic effects produced by the activities of investment/expenditure of the identified agents and the consequent multiplying effects captured from an input-output model.

The World Games represented a new income flow to the city of Cali of $101.036 million pesos (≡US$53.4 mill.) and 9.598 jobs were created (≡7,711 full-time jobs). Additionally, 2,174 foreign tourists and 11,250 national tourists were attracted to the city.

The article contributes with innovative aspects methodologically speaking, useful for future studies of economic impact in cities with low tourism located in developing countries.

Despite the boom corporate social responsibility (CSR) and sustainability are enjoying nowadays in the agendas of both small and big companies, we still have difficulties in providing a clear definition of the concept of sustainability. There is no consensus on the criteria to be used to define and enhance responsible management that creates sustainable development.

After a systematic revision of the literature, authors have been mapping the limits of the research already done at different levels, dimensions, and horizons, so we do have a 360° map of the research on sustainability. Future developments are also explored to enrich and align the diverse approaches demanded to define this wide, complex, and by now, equivocal concept and the conclusions reveal the many gaps not yet covered in the research field, signposting key issues for further work.

Directing schools of high complexity in disadvantaged social contexts with high rates of emigration requires skills for emotional leadership. Directors with self-managing capacities are needed to manage their own emotions. They also need to mobilise people (teachers, students and families) by focussing on their feelings of satisfaction, identification with the group, belonging, joy, success, unity and cohesion.

The content of this chapter presents the study of the emotional management of directors who perform their work in two highly complex schools in Catalonia, Spain. The views of these directors as well as teachers and families examine: (1) the construction of their professional identity, (2) their social and ethical commitment to the community, (3) the orientation towards the values of social justice and (4) their emotional leadership practices focussed on personal attention towards all of the actors in the school community.

The chapter concludes with 10 suggestions that can be useful to improve the professional practice of school directors. These should also be taken into account when designing and implementing initial and ongoing training programmes for school leaders and to inspire ideas for future research.

The purpose of this paper is to characterize the agricultural activities and past experiences in professional training in the context of mobile learning in different countries (Portugal, Spain, Slovakia, Hungary, UK, Italy and Turkey).

For the survey, a questionnaire was prepared in English and Portuguese and then translated into the languages of the participating countries. It was delivered electronically for answering online by adults only. The participation was voluntary and in the end 133 consented valid questionnaires were obtained. For the treatment of the data, SPSS was used and basic descriptive statistics tools were applied, together with tests, namely, crosstabs and χ² tests, considering a level of significance of 5 percent.

The results showed that the majority of the participants presently have some agricultural activity and one-third is thinking about starting one in the future. Most of the participants want to produce food organically, with significant differences among the countries studied in this paper. Most of the participants were enrolled in training activities in agriculture, especially those with higher education. This participation showed significant differences between countries as well as according to the dimension of the farms owned by the participants. A significant association was found between being a teacher in forming activities related to agriculture and being a farmer. When compared to distance learning, the training activities in classroom were the most frequent, with significant differences among the countries.

This study allowed characterizing the learning activities in the field of organic agriculture and established vision for planning of future training programs, in different countries, with maybe different social, educational and cultural realities.

Because the study included the participation of people from several countries all around Europe, the results obtained enrich the scientific area of training in organic farming, in view of distance learning vs classroom learning on a more global basis.

The academic literature and research lines exploring the effect of quality improvement methods on environmental performance still remain in early stages. The purpose of this paper is therefore to investigate, through a systematic review of the existing academic literature, the environmental (green) impact of using quality and operations improvement methods such as Lean, Six Sigma and Lean Six Sigma. This includes the impact on energy saving and the usage of natural resources.

This study follows a systematic literature review approach through which it analyses research papers published in top 16 operations and quality management journals. No specific time frame was established, but a set of keywords were used to short-list the articles. A sample of 70 articles was finally short-listed and analysed to provide a discussion on environmental concerns related to Lean, Six Sigma and Lean Six Sigma.

The comprehensive review of short-listed articles indicates that both Lean and Six Sigma can be considered effective methods to support the conservation of resources, combat global warming and saving energy. Various scholars provide evidence of this, and as such, organisations should not only consider these methods to manage quality and improve operational performance but also meet environmental regulations. A set of research questions that demands further investigation has also been proposed based on the findings of this research.

This study is limited to a sample of 70 articles collected from top 16 operations and quality management journals. The search of journals is also limited to a set of key words (“Lean”, “Green”, “Six Sigma”, “environment”, “sustainable” and “sustainability”) used to short-list the sample size.

The study shows that organisations can consider the adoption of Lean, Six Sigma and Lean Six Sigma to meet environmental regulations, save costs and also meet quality management standards. This will contribute in helping organisations to formulate more effective and inclusive strategies which do not only consider the quality and operational dimensions but also the environmental dimension.

Literature exploring the environmental/green impact of quality management methods commonly used in industry is limited. There is also a lack of studies aiming to investigate the green impact of Lean and Six Sigma in top operations and quality management journals. The study focusing on investigating the green impact of Lean, Six Sigma and Lean Six Sigma methods altogether is also a research first of its kind.

In this survey we present (after an Introduction) a guide to the major doctrinal trends of Spanish accounting of the period, classified in various categories: different views of the scientific nature of accounting, dominant theories, purposes of accounting, special areas, views on classification and on the recording of transactions, views on valuation and depreciation, cost accounting, inflationary issues, auditing, accounting terminology, historical concerns, and the practical orientation of publications. A separate section offers further details about prominent Spanish scholars; it is followed by the conclusion. The latter indicates that during the period under investigation, Spanish accountants contributed little to novel accounting thought, but strongly relied on French and Italian doctrines, though neglecting German ideas. Despite of this, Spanish accountants were aware of many theoretical and instrumental novelties of the day, and applied them without substantial delay to their own environment.

Señor Ruiz‐Morales emphasized at the outset the diversity of the economy of Spain. Not only was Spain cut off from the rest of the European continent by the Pyrenees, but land communications between one region of Spain and another were greatly handicapped by the mountainous nature of the country. The centres of both industrial and agricultural activity lay along the coastal belt, from Bilbao in the north to Barcelona in the south. In the centre was the meseta, the high plateau, dominated by Madrid. In the case of agriculture it was important to distinguish between the land distribution of the south (on the latifundia system) and the very small holdings (minifundia) of the north. Crop growing was concentrated in the valleys and the semi‐tropical climate of the south enabled Spain to export citrus fruits. Most of Spain's mines had been worked for a long time and were nearly exhausted. The country's deficiency was in two vital sources of power—coal and oil. Hydro‐power was, however, being utilized in the Pyrenees (for the Barcelona industrial region) and where the Douro and the Tagus dropped into Portugal. In the early ‘thirties Spain had a considerable gold reserve, but this had been lost to Russia, for the gold had been sent to that country at the time of the Spanish Civil War. Foreign aid was providing an important incentive to economic progress.

This paper aims to provide information about the structure of collaborative work among Argentinian economics. The study provides specific applied research of social network analysis focus on this profession in this specific country.

The contribution opted for applying social network analysis tools to papers presented in a congress and published in its proceedings. The authors focus in detecting main actors, groups of co-authorship, professionals acting as bridges between groups and differences between genders.

The paper provides empirical insights about how co-authorship has evolved between Argentine economists. The authors find that structural properties of the network, main actors, both male and female, main universities or center that affiliates them, a gender gap that might be closing out.

The paper focuses on the network for the period 1964-2014 without a more detailed dynamic. It also does not explain main topics worked by the authors.

The work provides knowledge about how groups are created in Economics in Argentina, how cooperation has evolved and what has been the role of women in this development. It also shows how different departments and entities collaborate with diverse success in the creation of new knowledge in Economics in Argentina.

The paper works with data from a source of information non-previously studied and contributes in explaining a particular type of collaborative work in a profession in Argentina.

This study aims to assess the potency and dose of Δ-9-Tetrahidrocannabinol (THC) and Cannabidiol (CBD) in cannabis joints. This will enable better estimates of the degree of exposure in a user and contribute towards a better understanding of potential harmful effects.

Analysis of intact joints confiscated by law enforcement on the street in the autonomous region of Castilla y León (Spain) during the years 2017–2019.

This study analysed THC, CBN and CBD in marijuana joints (N = 744). Joints contain cannabis and tobacco (N = 729), had a median net weight 0.69 g (IQR = 0.28); concentration THC median was 6.30%(IQR = 4.51) and THC median dose 42 mg (IQR = 32.75). A total of 35.5% mixed joints contained CBN – median percentage 0.61% (IQR = 0.51). CBD was detected 10.3% of mixed joints – median percentage 0.13% (IQR = 0.12) and median dose 1 mg (IQR = 0.92). CBD/THC ratio presented median value of 0.02 (IQR = 0.02). The samples analysed comprised pure cannabis joints (N = 15), with THC median 11.86% (IWR = 6.30) or median dose of 118 mg.

The study found high values for concentration and dose of THC and CBD in cannabis joints, warning of high exposures for the user and associated potential consequences. The results obtained contribute new perspectives on the definition of a standard cannabis unit.
