This study uses a case study approach to describe a phenomenon. The data collected from observation of the real-world environment.

The benefits of OpenVPN are the following: librarian can access the Osiris and other resources remotely and safely; OpenVPN protects the connection when accessing the Osiris; and librarian can also manage Osiris systems easily to control access, monitoring the users efficiently. However, there are some drawbacks of OpenVPN, such as network infrastructure dependency, require stabile internet connection, configuration complexity, to arrange and configurate OpenVPN needs skills and knowledge on the related field, data protection and security breach.

The originality of this study is the use of OpenVPN to access Osiris that is managed by library. There are some variables to determine the benefits and drawbacks of the OpenVPN such as managing access, data security and efficiency. This study gives an original contribution to the use of OpenVPN in academic libraries.

The Design For Six Sigma (DFSS) methodology is one of the most important to achieving excellence in an organization’s product development process. This paper aims to propose a roadmap for product development based on the DFSS for the consumer durables manufacturing industries. The proposed roadmap presents a systematic approach to the phases of the product development process, integrating the statistical techniques and quality tools that should be used in each phase.

This study presents a detailed roadmap for product development, which was built by identifying gaps in the DFSS methods, based on previous studies on the subject. In this step, the opportunities are provided in all phases from creation to discontinuation of the product in the market. In addition, the roadmap presented was validated by team of stakeholders in the product development process of different industrial companies.

The proposed roadmap for the product development process based on six sigma design suggests a visual tool with sequential steps and techniques that allow you to follow the evolution of the development process from idea conception until the product is discontinued in the market. Identifying the priorities of organizations, especially the consumer, regarding the quality and reliability of the product.

The roadmap seeks to facilitate an understanding of the important stages of the product development process and to provide an approach to improving and optimizing the product before the manufacturing process step through the principles of DFSS methodology. This research provides a guide step by step to apply statistical techniques and quality tools in the product development process to achieve high quality and six sigma level in the manufacturing process.

The proposed roadmap of this research combines design for sigma and product development concepts, covering a wide spectrum of relevant activities that include the product development process, the application of statistical techniques and the design of high-quality durable consumer goods to match manufacturing technologies.

Despite gender parity in the general working population, the higher up one looks in ranks within the firm the fewer women one finds. This under-representation of women in top positions at firms is purportedly even more acute in Latin America and the Caribbean (LAC). LAC is a large and increasingly important region of the world where women are well-represented in the workforce and are comparatively better educated than men. Documenting if this resource is utilized at full potential is therefore of crucial importance. The purpose of this paper is to document the level and impact of female representation at the executive level in the region, as no systematic study exists on this topic.

The authors collect an original database of publicly listed companies to determine prevailing gender ratios among board members and executives in LAC region. The authors then estimate whether companies with women board members are more likely to appoint women executives. Finally, the authors estimate whether measures of female leadership at the firm are correlated with company performance.

The authors find that women are as under-represented in LAC as in the USA, but much less so in the Caribbean. The authors find that companies with women board members are more likely to appoint women executives in LAC. The authors find that measures of female leadership at the firm are correlated with company performance but only regarding board membership and only when the proportion of women on the board is greater than 30 percent. Again composition effects are important. Overall, the authors conclude that the LAC region exhibits empirical regularities about under-representation of women in leadership positions at the firm that are very similar to those found for high-income countries in Europe and North America.

The authors are the first and so far unique systematic study exists able to document the level and impact of female representation at the executive level in the region.

The purpose of this paper is to analyze the relationship between multinationality and firm performance (M-P) in Latin American companies, commonly referred to as multilatinas. The study conceptualizes the depth (intensity) and breadth (geographical scope) of internationalization and examines their effect on financial performance. Although scholars have studied how internationalization in various contexts and industries affects performance, little is known about firms in Latin America.

The authors conducted an analysis of the effect of the depth and breadth of multilatina internationalization on financial performance by creating a database using information from America Economia, a specialized Chilean magazine that publishes an annual ranking of multilatinas. Additional data came from the Osiris database of Bureau Van Dijk and Compustat. The hypotheses were tested using an autoregressive heteroskedastic model.

The results show that the extent of the depth and breadth of internationalization affects financial performance. Multilatinas’ depth of internationalization has a curvilinear (U-shaped) impact on performance while breadth has an inverted curvilinear impact on performance.

The theory portion and results expand the literature on firm internationalization and performance by distinguishing between two types of international firm expansion, depth and breadth, and discussing how each contributes to different stages of the three-stage theory of multinationality and performance.

The findings indicate that multilatinas benefit from their regional expansion, but outside Latin America, expansion has a negative effect on financial performance. They also show that firms can implement different types of internationalization strategies in terms of intensity and scope to achieve better performance.

Este artículo analiza la relación entre la multinacionalidad y el desempeño de la empresa (M-P) en compañías latinoamericanas, conocidas como multilatinas. El estudio conceptualiza la profundidad (intensidad) y extensión (alcance geográfico) de la internacionalización, y examina su efecto en el desempeño financiero. Aunque varios investigadores han estudiado cómo la internacionalización en diversos contextos e industrias afecta el rendimiento, poco se sabe con respecto a las empresas en América Latina.

Los autores realizaron un análisis del efecto producido por la profundidad y extensión de la internacionalización de la multilatina en el desempeño financiero, mediante la creación de una base de datos con información de América Economía, una revista chilena especializada que publica anualmente un ranking de multilatinas. Datos adicionales provienen de la base de datos Osiris de Bureau Van Dijk y de Compustat. Las hipótesis fueron probadas usando un modelo heterocedástico autoregresivo.

Los resultados muestran que el grado de profundidad y extensión de la internacionalización afectan el rendimiento financiero. La profundidad de internacionalización de las multilatinas tiene un efecto curvilíneo (en forma de U) sobre el desempeño financiero, mientras que la extension geográfica tiene un efecto curvilíneo invertido en dicho desempeño.

La sección teórica y los resultados extiende la literatura sobre la internacionalización y el desempeño de las empresas al distinguir entre dos tipos de expansión internacional: profundidad y extensión. También se discute cómo cada uno contribuye a las diferentes etapas de la teoría de la multinacionalidad y desempeño.

Los resultados indican que las multilatinas se benefician de su expansión regional. Sin embargo, fuera de América Latina, dicha expansión tiene un efecto negativo sobre el desempeño financiero. También se señala que las empresas pueden implementar diferentes tipos de estrategias de internacionalización en términos de intensidad y alcance para lograr un mejor desempeño.

The purpose of this paper is to investigate the determinants of IJV performance expectations for a sample of international joint ventures with parent firms from Europe, North America and Australia. A conceptual framework is proposed which identifies the determinants of IJV performance as the dominant control of the IJV by one parent firm, the level of autonomy granted to the IJV management, the level of trust between the partner firms, the effect of differences in the national cultures of IJV partners and the differences in the organizational cultures of IJV partners.

The study adopts a self‐administered questionnaire approach to examine the determinants of performance in the sample firms. The starting point for obtaining a sample of parent firms was the OSIRIS database. Paper copies of the questionnaires were posted to potential respondents. This was followed by an e‐mail to the same potential respondents with the questionnaires attached. In total, 109 usable questionnaires were obtained from respondent companies – 22 questionnaires were returned from the postal survey and 87 questionnaires were returned from the follow‐up e‐mail.

Predicted positive relationships between performance expectations and dominant control of the IJV, autonomy granted to the IJV management, and trust between the partner firms are supported by the data. The predicted negative relationship between performance expectations and national culture differences was not supported, however, the expected negative relationship between performance expectations and corporate culture differences was partially supported.

This study adds to the international business literature on IJVs and provides new empirical evidence in the context of Europe, North America and Australia.

Ship route prediction (SRP) is a quite complicated task, which enables the determination of the next position of a ship after a given period of time, given its current position. This paper aims to describe a study, which compares five families of multiclass classification algorithms to perform SRP.

Tested algorithm families include: Naive Bayes (NB), nearest neighbors, decision trees, linear algorithms and extension from binary. A common structure for all the algorithm families was implemented and adapted to the specific case, according to the test to be done. The tests were done on one month of real data extracted from automatic identification system messages, collected around the island of Malta.

Experiments show that K-nearest neighbors and decision trees algorithms outperform all the other algorithms. Experiments also demonstrate that linear algorithms and NB have a very poor performance.

This study is limited to the area surrounding Malta. Thus, findings cannot be generalized to every context. However, the methodology presented is general and can help other researchers in this area to choose appropriate methods for their problems.

The results of this study can be exploited by applications for maritime surveillance to build decision support systems to monitor and predict ship routes in a given area. For example, to protect the marine environment, the use of SRP techniques could be used to protect areas at risk such as marine protected areas, from illegal fishing.

The paper proposes a solid methodology to perform tests on SRP, based on a series of important machine learning algorithms for the prediction.

Different from most academic publications about tourism in Brazil, this paper provides an overarching and comprehensive perspective. Analysing key developments, and focusing on the period 2000–2019, this paper also considers long-standing structural issues that hinder tourism development. Although this viewpoint paper deals with Brazil, very similar issues can be identified for many countries worldwide.

This viewpoint paper is a combination of reflections by leading Brazilian tourism academics; most are members of ABRATUR, the International Academy for the Development of Tourism Research in Brazil. This paper uses secondary data from the grey (e.g. government reports) and academic literature to support this opinion paper. The tourism-related topics covered in this paper include economics, policy and planning, marketing, transport, nature-based tourism, gastronomy, hospitality and education, amongst others.

Brazil has missed several unique opportunities to place it as a destination of international renown. Since the 1990s, efforts to support regional tourism development have achieved only moderate success as political instability, violence and corruption have impacted tourism. A lack of a coordinated approach between the various levels of government, a shortage of tourism data and a long-term supra-government marketing campaign, among other factors, have meant Brazil has missed several critical opportunities in the 2010s to establish itself as a leading tourism destination in the global market.

From leading tourism academic experts in Brazil, a unique opinion paper offers an overview of the critical development issues in 2000–2019. The paper presents matters that have hindered potential tourism contributions to the largest nation in South America. While these matters may be specific to Brazil, many of these challenges are not dissimilar to those in other emerging (democratic) nations. The authors offer several public policies and technical recommendations to scaffold tourism development towards the 2030 agenda.

A diferencia de la mayoría de las publicaciones académicas sobre el turismo en Brasil, este artículo ofrece una perspectiva global e integral. Al analizar los desarrollos clave y centrarse en 2000–2019, este documento también considera problemas estructurales de larga data que obstaculizan el desarrollo del turismo. Aunque este documento trata de Brasil, se pueden identificar problemas muy similares en muchos otros países del mundo.

Brasil ha perdido varias oportunidades únicas para colocarse como un destino de renombre internacional. Los esfuerzos realizados desde la década de 1990 para apoyar el desarrollo del turismo regional solo han logrado un éxito moderado debido a que la inestabilidad política, la violencia y la corrupción han impactado al turismo. La falta de un enfoque coordinado entre los distintos niveles de gobierno, la escasez de datos turísticos, una campaña de marketing supra gubernamental a largo plazo, entre otros factores, han significado que Brasil haya perdido varias oportunidades críticas en la década de 2010 para establecerse como un destino turístico líder en el mercado global.

Un artículo de opinión único de destacados expertos académicos en turismo en Brasil, que ofrece por primera vez una visión general de los problemas críticos del desarrollo desde la década del 2000. El documento presenta asuntos que han obstaculizado las posibles contribuciones del turismo a la nación más grande de América del Sur. Si bien estos asuntos pueden ser específicos de Brasil, muchos de estos desafíos no son diferentes a los de otras naciones (democráticas) emergentes. Ofrecemos diversas recomendaciones técnicas y de políticas públicas para impulsar el desarrollo turístico hacia la agenda 2030.

The purpose of this paper is to compare the value relevance of various accounting information disclosed in financial statements of manufacturing companies listed on the stock markets of Korea, Japan, and China over ten years from 2006 to 2015.

The study uses Ohlson (1995) valuation model for empirical investigation and the financial data extracted from the OSIRIS DB to analyze the enterprise value relevance of accounting information for Korean, Chinese, and Japanese companies and to investigate the differences among them.

The results of the empirical analysis are as follows. First, the coefficient of accounting earnings is the highest in the samples of all firms in Korea, Japan, and China, followed by the coefficients for operating income, net cash flow, book value, and net operating cash flows. Next, Japan has the largest book value, followed by Korea, but China has a negative value. Japan has the largest coefficient of accounting earnings and net operating cash flow, followed by Korea and China. Japan has the largest coefficient of net cash flow and operating income, followed by China and Korea. The results show that the value relevance of accounting earnings is the largest among independent variables related to firm value, but the net operating cash flow is the smallest. In addition, the authors observe that the coefficient of Japan is the largest of all independent variables when compared by country.

The contribution of this study is that it shows the comparative value relevance of accounting information in most economically developed Asian countries such as Korea, Japan, and China. In addition, it is worth showing the characteristics of the national value decision variable by showing different incremental value relevance levels among the three countries.
