The purpose of this paper is to examine global trajectories, dynamics, and tendencies of software piracy to ease the benchmarking of current efforts toward harmonizing the standards and enforcements of intellectual property rights (henceforth IPRs) protection worldwide.

For that purpose, the authors estimate dynamic panel data models for 99 countries over the period 1994-2010.

The main finding suggest that, a genuine timeframe for standardizing IPRs laws in the fight against software piracy is most feasible within a horizon of 4.3-10.4 years. In other words, full (100 percent) convergence within the specified timeframe will mean the enforcements of IPRs regimes without distinction of nationality or locality within identified fundamental characteristics of software piracy. The absence of convergence (in absolute and conditional terms) for the World panel indicates that, blanket policies may not be effective unless they are contingent on the prevailing trajectories, dynamics and tendencies of software piracy. Policy implications and caveats are also discussed.

It is the first attempt to empirically assess the convergence of IPRs systems across countries.

The importance of sustainability in architecture currently necessitates the integration of innovative teaching strategies on the subject into architecture programs. This study aims to introduce and examine peer learning pedagogy by peer tutoring to educate architecture students in sustainable design.

Based on class assignments proposed in two different architecture sustainability-focused courses in the second and fourth years of the Bachelor of Science in architecture program, a total of 103 students assessed the proposed peer learning experience and its impact on their sustainability mindsets and education. Subjective surveys for evaluating the peer learning experience were designed and delivered at different stages of the course sequences. A total of 502 survey responses were obtained in the study.

The qualitative and quantitative data analysis confirms that the proposed peer learning by peer tutoring increased students’ knowledge, motivation and commitment to sustainable design. In addition, participants became more confident in applying sustainable design skills and their academic grades improved more than 25% compared to previous courses using traditional teaching methods.

Traditional architecture education has long been criticized for their pedagogical methodologies based primarily on passive learning. Recently, these programs have begun to prepare students to become active learners and communicators in collaborative and multidisciplinary environments. A mixed-method approach of combining pre-/post-experience surveys and analysis of final grades was used to determine the level of success and the quantifiable behavior change delivered by students involved in this peer learning experience.

The purpose of this paper is to investigate the effect of a sealing protective treatment on the water absorption and mechanical properties of acrylonitrile butadiene styrene (ABS)-printed parts by fused deposition modelling. Protective products include aqueous acetone solutions with different concentrations, polyurethane wood sealer and aqueous acrylic-based varnish.

Open porosity was estimated by the absorption coefficient and the total amount of water retained, obtained from water absorption tests. Mechanical characterization was performed by compressive and tensile tests. Different specimens with different build directions and raster angles were used.

The treatments with acetone solutions were not effective in reducing the porosity of ABS parts, as the amount of acetone that reduces effectively the porosity will also affect the sample dimensional stability. The polyurethane treatment was found to reduce the absorption coefficient, but the maximum water content and the open porosity remain almost unchanged in comparison with the ones obtained for untreated specimens. The treatment with an acrylic-based varnish was found to preserve the dimensional stability of the specimens, to reduce the open porosity and to maintain the compression and tension properties of the specimens in different build directions and raster angles.

Surface modification for water tight applications of ABS 3D printing parts enables new designs where both sealing and the preservation of mechanical properties are important. As per the knowledge of the authors, the water absorption and the mechanical behaviour of ABS 3D printed parts, before and after treatment, were not previously investigated.

This research examines the likelihood that Panamanian and Colombian banks listed on their respective stock exchanges voluntarily disclose intangible liabilities based on such variables as their size, profitability, indebtedness, age and growth. The presented findings concur with agency theory, signalling theory and the owner-cost theory.

The authors propose a probabilistic model to test the influence of size, profitability, indebtedness, age and growth on the disclosure of intangible liabilities. The dependent variable, the disclosure index, was constructed from a dichotomous approach using Harvey and Lusch's (1999) model, which has 24 characteristics, plus six that we added in our research. These were grouped into four categories: procedures, human activity, information and organisational structure.

Banks in Panama and Colombia with a larger size, higher profitability, lower age and higher growth are more likely to disclose more information about their intangible liabilities. However, indebtedness does not serve as a determinant of the disclosure of these liabilities, even though its relationship is negative.

The limitation of the research was the voluntary disclosure of information about these liabilities on firms' websites.

The contributions of this research are as follows. First, we used an intangible asset disclosure methodology to verify the disclosure of intangible liabilities, in line with Harvey and Lusch's model, as well as providing another six indicators, thereby producing an extended model. Second, being the first empirical research to study the disclosure of intangible liabilities in Panama and Colombia opens a door to future research on this topic.

This research provides a significant practical contribution to society because banks listed on public stock markets, understanding that undisclosed intangible liabilities lead to opportunity costs in their profitability, might tend to disclose more information, thus promoting greater transparency in the market.

The main contribution of this research is applying an intangible asset disclosure methodology to the disclosure of intangible liabilities, following Harvey and Lusch's (1999) model, as well as the creation of an expanded model.

This paper aims to present a system that is fully capable of addressing the issue of detection, tracking and following pedestrians, which is a very challenging task, especially when it is considered for using in large outdoors infrastructures. Three modules, detection, tracking and following, are integrated and tested over long distances in semi-structured scenarios, where static or dynamic obstacles, including other pedestrians, can be found.

The detection is based on the probabilistic fusion of a laser scanner and a camera. The tracking module pairs observations with previously detected targets by using Kalman Filters and a Mahalanobis-distance. The following module allows to safely pursue the target by using a well-defined navigation scheme.

The system can track pedestrians from static position to 3.46 m/s (running). It handles occlusions, crossings or miss-detections, keeping track of the position even if the pedestrian is only detected in 55/per cent of the observations. Moreover, it autonomously selects and follows a target at a maximum speed of 1.46 m/s.

The main novelty of this study is the integration of the three algorithms in a fully operational system, tested in real outdoor scenarios. Furthermore, the addition of labelling to the detection algorithm allows using the full range of a single sensor while preserving the high performance of a combined detection. False-positives’ rate is reduced by handling the uncertainty level when pairing observations. The inclusion of pedestrian speed in the model speeds up and simplifies tracking process. Finally, the most suitable target is automatically selected by a scoring system.

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.

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.

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.

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.

In the macroeconomic environment of the Iberian Peninsula, this paper aims to examine the influence of corporate governance characteristics on corporate sustainability performance. The purpose of this paper is to address corporate practices while determining which corporate governance characteristics can improve corporate sustainability, considering, for this purpose, three dimensions of sustainability: economic, environmental and social.

This sample comprises 99 non-financial companies of the Iberian Peninsula, during the 2013–2017 period. The authors have used the panel data methodology, specifically the generalized method of moments (GMM) estimation method proposed by Arellano and Bover (1995) and Blundell and Bond (1998) to test the hypotheses formulated.

The results obtained have shown that corporate sustainability performance is affected differently depending on the sustainability dimension that is considered. Specifically, the economic dimension is determined by public debt, the board size, board diversity and the existence of an audit committee. Regarding the environmental dimension, the board size and the presence of the audit committee, as well the corporate social responsibility committee, are the most important determinants. Finally, the social dimension was influenced by the board size, audit committee and the control variable of capital structure, which means that in this dimension, the sources of financing used by the company also help in determining its levels of social concern.

To the best of the authors’ knowledge, this is the first time that a study has been carried out in the Iberian Peninsula on the corporate sustainability using GMM-system model for three dimensions of sustainability. Corporate sustainability depends on external and internal factors of companies. Therefore, regulators and managers should realize that they will have to be more effective in their statements.

Highlights the lack of comprehensive collections of Hispanic materials in the USA. Discusses how and why this situation should be remedied. Suggests suitable bibliographies as a starting point for collection building. Describes the assessment of a Hispanic American collection at the University of California, Irvine.

Our aim is to analyze the type of lender and the debt maturity of Chilean firms as a function of their ownership structure and their growth opportunities. We perform the empirical analysis using an unbalanced panel data of 169 firms from 1990 to 2001. Our results show that Chilean firms with growth opportunities, ownership concentration, and a need for external funds issue short‐term bank debt to finance their new investments. This financing source is an efficient mechanism in Chile to alleviate agency and asymmetric information problems. The Chilean institutional environment influences firms’ decisions on banking debt.
