This study aims to analyse the influence of the pillars (hard and soft skills) of digital academic entrepreneurship on students' entrepreneurial intention.

This was done by adopting a quantitative methodology involving empirical research with a sample of 761 university students from two countries and adopting structural equation analysis to validate the theoretical model proposed.

The results indicate a direct influence between hard and soft skills and entrepreneurial intention, and a positive, indirect influence between these and entrepreneurial intention mediated by the dimensions of the theory of planned behaviour (TPB) – entrepreneurial attitude, subjective norms and perceived behavioural control. Therefore, the pillars of digital academic entrepreneurship have a direct and indirect influence on university students' entrepreneurial intention.

This study also contributes to better operationalization of entrepreneurial education in university environments, since the development of hard and soft skills can be planned better based on the model proposed here. Considering the relations between the dimensions of hard and soft skills and those of TPB, this study shows there can be an influence on students' entrepreneurial intention.

In this study, a new and innovative construct is inserted in the model of entrepreneurial intention: “structural pillars of digital academic entrepreneurship” through structural equation modelling, to determine the degree of influence of these pillars (hard and soft skills) constructs on HEI students' entrepreneurial intention.

Digital technology changes the organizational structure of traditional firms, creating opportunities for entrepreneurship. These modifications are known as “digital transformation” (DT). In addition, higher education institutions (HEIs) are altering the form of student–lecturer and teaching–learning interaction, where DT restructures the bases of soft skills (SS). Since SS are difficult to measure, this study aims to analyze the bases of SS for digital academic entrepreneurship, responding to the following research question: What are the bases of digital academic entrepreneurship and how are they formed?

An extensive integrative review of the literature revealed that due to the editable, re-combinable, reprogrammable and generating nature of digital technology, the basis of DT, it is necessary to develop SS in higher education students.

The results show that the competencies can be developed considering three major groupings: (1) individual characteristics, (2) cultural characteristics and (3) knowledge sharing.

Since SS are not easily taught, this study shows how the use of digital tools can help and support this type of process. It is suggested, therefore, that those in charge of HEIs should use the pillars presented in the framework proposed here to guide their institutions' strategic planning. With these pillars in mind, the aim is to stimulate an entrepreneurial mentality in students and develop digital academic entrepreneurship.

An innovative conceptual model of digital academic entrepreneurship is proposed from the perspective of SS, where the interlinking of those groupings is permeated by DT, as well as the disruptive role of digital technology, leading to the development of an entrepreneurial mentality in HEI students.

This paper seeks to analyze the relationship between China and the Northeast region of Brazil, aiming to identify how the renewable energy sector is being developed.

The authors analyzed secondary data from the official databases from China-Brazil chambers of commerce to establish the main points related to renewable energy in Brazil's Northeast.

It is possible to notice the main investments, highlighting the wind energy as a more prominent source recently. The authors also point the huge influence from China on Brazil's Northeast energy sector.

It is difficult to identify the amount of Chinese capital due to the large number of mergers and acquisitions that has been taking place in recent years.

Identification of regions that have been receiving investments and the main interests of Chinese investors in the renewable energy sector.

Demonstration of how the renewable energy sector has taken an important turn in Brazil due to Chinese investment.

To evaluate a regional consortium, analyzing its strategies for partnerships with China to help each other in global questions, as is the case of renewable energy.

In 2014, after nearly 150 years as one of Portugal's most wealthy and powerful families, the Espirito Santo family completely lost control of its empire, which included Banco Espirito Santo, Portugal's largest bank by market capitalization and second-largest private-sector bank in terms of assets, along with stakes in numerous financial, non-financial, privately held, and publicly traded companies. During the European financial crisis of 2010 to 2014, many of the family's companies required capital investment. To avoid family equity dilution, the family's patriarch, Ricardo Espirito Santo Silva Salgado, engaged in a creative money-go-round structure whereby Banco Espirito Santo would legally raise short-term commercial paper with high interest rates and sell them to third parties that were partially owned by the Espirito Santo family. These third parties then would sell that paper back to the bank's retail clients as safe investments similar to Portuguese deposits. The plan failed, and the house of cards that was the Espirito Santo empire collapsed. Students will consider whether Salgado and the board of Banco Espirito Santo acted appropriately or if they failed their fiduciary duties to the non-family shareholders of the bank.

The purpose of this paper is to present a methodology for forecasting the availability off-highway trucks used in a fleet for large transport operations of ore and sterile rock from an open pit mine.

This methodology enables the estimation of the number of hours of preventive and corrective maintenance required, which are used to predict truck availability. The authors used historical data for the maintenance strategy based on the hours of operation.

These data are statistically analyzed to obtain the key quantities and statistical models required to project availability and to develop equipment replacement plans.

A methodology for forecasting availability to assets in open pit mining industry was implemented.

This paper aims to examine the origins and trajectory of the Brazilian corporate social responsibility (CSR) movement in relation to political economic developments in Brazil during and prior to the 2000s.

This paper relies on a historical political account that traces the evolution of the main actors in the CSR movement since the democratization period, details the contacts established with relevant political and civil society groups and outlines the adaptation of their agenda to the changing context.

The long association between a faction of Brazilian business and the Workers’ Party (PT) and the overlapping state – society relations characteristic of the Brazilian political economy explain the domestic and international standing of the Brazilian CSR movement, in particular since 2003 when Lula da Silva came to power.

The trajectory of Brazilian CSR and participation in related global initiatives cannot be explained through market-based or isomorphic approaches traditionally used to analyze the diffusion of governance mechanisms in the Global South. Rather, it highlights the relevance of local political structures in shaping involvement in global governance initiatives.

University students use web-based course registration systems to search, select, and register to courses. Despite having an important role at universities, course registration systems often pose usability problems to users. In this project, the authors assessed the usability of a web-based course registration system, proposed an improved model for such systems, and evaluated the model. The paper aims to discuss these issues.

The authors conducted a series of user studies to achieve the objectives. First, the authors performed a usability study to evaluate the course registration system at MacEwan University (myStudentSystem). Based on the study results, the authors designed and developed a prototype that addresses the limitations of the system. Second, the authors conducted a usability test to get feedback on the prototype and improve its design features accordingly. Finally, the authors performed a summative evaluation to assess the usability of the prototype and myStudentSystem.

The summative evaluation results showed that the design improved the overall system usability and user satisfaction. Most participants preferred the prototype to myStudentSystem.

The authors tested the prototype in controlled experimental settings, and the participants were limited to undergraduate students at MacEwan University. These conditions may limit the generalizability of the results. Further studies that deploy and test the prototype in the real world are necessary to validate findings.

Based on the studies, the authors outline guidelines for designing web-based course registration systems and advocate the use of new technologies to create highly interactive web applications. The authors' model can assist software developers in designing and implementing web-based course registration systems at universities.

The purpose of this paper is to seek to clarify whether the fair value (FV) of Brazilian banks securities is relevant for investors in times of crisis.

The information gathered for 14 quarters, 2007-2010, of a cross-sectional sample of banks was used for the purpose of explaining the value of shares based on amortized cost and the FV of securities, the book value of equity and the financial crisis. The return on shares was regressed based on the realized and unrealized gains and losses on securities, adjusted income and the crisis.

The results indicated that the FV is relevant. The results also corroborated the hypothesis that, during the crisis, there was a decrease in the relevance of the FV of securities since the accounting practices adopted in Brazil did not specify how to estimate FV, as required by SFAS 157, neither did they require disclosure of the FV hierarchy, as established International Financial Reporting Standards (IFRS) 7. It was concluded that FV has incremental explanatory power over equity, but not over amortized cost. Furthermore it possible to conclude that quarterly unrealized gains and losses on securities are not relevant, which could be explained by possible tax planning practices, since, in Brazil, the mark-to-market adjustment of securities is only deductible, or taxable, when settled. However, the realized and unrealized gains and losses are value-relevant during the period of financial crisis.

This study provides empirical evidence about the relevance of FV during the financial crisis in Brazil.

The purpose of this paper is to present eight papers selected from ALTEC 2015 that provide an overview of innovation in Latin America.

This editorial seeks to define innovation by examining its conceptual foundations. It considers innovation beyond firms and technology to address other forms, such as social and institutional innovations. Thereafter, it discusses innovation in the context of Latin America and suggests means by which to stimulate it in the region. Finally, the authors present the eight papers included in this “special edition.”

The major findings of the paper are that it considers non-technological innovation within firms, innovation beyond the firm and innovation beyond technology. Moreover, it helps to better understand a core issue of innovation in Latin America, which is the focus on macroeconomic policy instead of microeconomic stimuli.

A broader understanding of the concept of innovation is of notable importance. Innovation implies the recognition of issues related to the market (firm), but also to the community (society) and to humanly devised constraints (institutions). Technology is only one part of it. For this special issue, the selected articles highlight the efforts made by different authors to contribute to innovation studies in the editors’ region.

Este número presenta ocho manuscritos seleccionados del ALTEC 2015, que ofrecen un panorama de la innovación en América Latina.

Esta editorial busca definir la innovación mediante la examinación de sus fundamentos conceptuales. Esto considera que la innovación va más allá de las firmas y la tecnología para abordar otros tipos, tales como innovación social e institucional. Posteriormente, se analiza la innovación en el contexto de América Latina y se sugieren medios para su estimulo en la región. Finalmente, presentamos los ocho artículos incluidos en esta Edición Especial.

Las principales conclusiones de esta editorial son que se considera la innovación no tecnológica dentro de las firmas, la innovación más allá de la firma y la innovación más allá de la tecnología. Además, esto ayuda a comprehender mejor una cuestión central de la innovación en América Latina, que es el enfoque en política macroeconómica en lugar de los estímulos microeconómicos.

Un mayor entendimiento del concepto de innovación es de gran importancia. La innovación implica el reconocimiento de las cuestiones relacionadas con el mercado (firma), pero también con la comunidad (sociedad) y con las restricciones humanamente concebidas (instituciones). La tecnología es solo una parte de esta. Para esta Edición Especial, los artículos seleccionados destacan los esfuerzos realizados por diferentes autores para contribuir a los estudios de innovación en nuestra región.

This paper aims to study the importance of polyphenols in human health and, based on recommendations on the replacement of carbonated drinks with nutritious beverages, like fruit juices, seeks to compare the polyphenol contents of natural and commercial juices.

The total polypheol content of 39 fresh and 159 commercial (100 percent and less than 50 percent) fruit juices was analyzed by the terbium sensitized fluorescence method. The ANOVA with Tukey post hoc test, and also an independent t‐test, were used for statistical analyses.

The mean polyphenol contents of fresh juices were significantly (p<0.001) higher than those of 100 percent commercials (5.34±2.7 vs 3.28±0.86 mg/l). In fresh juices the concentration ranged from 1.06±0.08 (pineapple) to 10.14±0.07 (sour cherry) mg QE/100 ml, while in 100 percent commercial juices the range was from 2.37±0.05 (orange) to 5.34±0.4 (pomegranate) mg QE/100 ml, and in <50 percent commercial juices they ranged from 1.04±0.7 (red grape) to 2.21±0.07 (white grape) mg QE/100 ml. The polyphenol contents of dark juices, in both fresh and commercial products, were significantly higher than others (p<0.001) and most fresh fruit juices possessed higher amounts of polyphenol than commercial ones. Although various juices differed in the quantity of total polyphenol, they can be considered as a good source of functional beverage.

This paper provides information about the polyphenol content of fresh and commercial (100 percent and <50 percent) fruit juices. To the best of the authors' knowledge, there have been no articles which aim to compare the polyphenol content of Iranian fresh and commercial fruit juices. For analysing the polyphenol contents, the newly developed terbium sensitized fluorescence method was used, and also the applicability of this new method was compared with the commonly used Folin‐Ciocalteau method.
