In the domain of Brazilian higher education, especially with regard to the National System for the Evaluation of Higher Education (SINAES), still lacks a reference ontology that can provide a basic conceptualization common to the different stakeholders of the domain. In this work we discuss the role of an ontology network developed with the purpose of improving the quality of the data produced by the different actors, institutions and systems within the domain of SINAES, in addition to facilitating their publication as open and connected data. In particular, we highlight the importance of the NeOn methodology to be followed during the development of an ontology network, demonstrating its role in defining the life cycle and in the articulation of the various processes and activities in the OntoSINAES ontological network development process. <![CDATA[The influence of organizational injustice in the motivation for the practice of cybercrimes]]> http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1807-17752018000100301&lng=en&nrm=iso&tlng=en RESUMO Esta pesquisa analisou como a percepção de injustiça organizacional motiva a prática de crimes cibernéticos no local de trabalho. Em uma investigação qualitativa e exploratória, foram realizadas entrevistas com 16 especialistas em segurança cibernética. Os dados foram analisados através da técnica de análise de conteúdo categorial. Os resultados sugerem que a percepção de injustiça produz sentimentos negativos como a baixa-estima, a frustração e a ausência de culpa, e que essas emoções motivam a prática de crimes cibernéticos. Diferentes percepções identificadas entre os entrevistados deste estudo, associadas à revisão da literatura referente ao tema, permitiram a proposição de um modelo conceitual.<hr/>Abstract This research analyzes how the perception of organizational injustice motivates the practice of cybercrimes in the workplace.

Due to its high potential, its adoption is being treated as the fourth industrial revolution. As with any major advancement in technology, it brings with it a spectrum of opportunities as well as challenges. On one hand, several applications have been developed or under development with potential to improve the quality of life significantly. As per a study, it is expected to double the annual economic growth rate of 12 developed countries by 2035. On the other hand, there is a possibility of loss of jobs. As per the available reports, the loss of jobs during the next 10-20 years is estimated to be 47% in the US, 35% in the UK, 49% in Japan, 40% in Australia, and 54% in the EU. In the era of globalization, no country can isolate itself from the impact of the advances in technology. However, the benefits can be maximized and losses can be minimized by putting necessary infrastructure and policy in place. Though several countries have decided their strategy for AI, India has not yet formulated its strategy. This article reviews the international as well as national scenario and suggests way forward for India. <![CDATA[Information Security Management Practices: Study of the Influencing Factors in a Brazilian AIR FORCE Institution]]> http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1807-17752018000100307&lng=en&nrm=iso&tlng=en ABSTRACT This article aims at analyzing the factors which influence the staff of the Brazilian Air Force Information Technology Board - DTI in relation to the understanding of the application of the Information Security Management practices.

Em ambientes de rápidas mudanças, a capacidade de reter conhecimentos pode conferir às organizações vantagem competitiva. Desafiadas por rotatividade de pessoal, processos de reorganização, fusões e aquisições ou terceirização, as empresas precisam criar alternativas para preservar sua memória. Utilizando o método de pesquisa qualitativa de caráter exploratório, efetuaram-se entrevistas em profundidade, com gestores de Tecnologia da Informação e usuários da Área de Negócios. Os resultados da pesquisa, na forma de sete categorias, indicaram que os SI apoiam algumas das funções da MO, e que sistemas capazes de lidar com informações menos estruturadas e decisões mais complexas produzem maior contribuição para a MO. A partir das categorias resultantes, elaborou-se um esquema relacional que pode servir de base para futuros estudos.<hr/>ABSTRACT With this article, we analyze how existing Information Systems (IS) in organizations can support the functions of Organizational Memory (OM). In rapidly changing environments, the ability to retain knowledge can give organizations a competitive advantage. Challenged by staff turnover, reorganization processes, merge and acquisitions, and outsourcing, companies need to create alternatives to preserve its memory. Using the exploratory qualitative research method, we conducted in-depth interviews with Information Technology managers and Business Area users. The research results, in the form of seven categories, indicate that the existing IS may support some functions of the OM, and systems capable of handling less structured information and complex decisions produce greater contribution towards OM. From the resulting categories, we elaborated a relational schema that can serve as a basis for future studies. <![CDATA[CHANGE IN CONSOLIDATED BUSINESS MODELS: THE STUDY OF RADIO TAXI COOPERATIVES IN BRAZIL AFTER THE INCLUSION OF MOBILE APPLICATIONS IN THE MARKET]]> http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1807-17752018000100311&lng=en&nrm=iso&tlng=en RESUMO O modelo de negócio de cooperativa de táxis foi modificado com a proliferação de aplicativos móveis.

There is abundant research that strain to improve interfaces by considering user needs through usability studies; however, few researches consider the incorporation of automatic brain mechanisms in order to improve knowledge communication performance. The objective of this research is not to establish a relationship between the negative stimulus presence and improved knowledge communication, but rather to show that the shape of this function follows the Yerkes-Dodson Law. Partial least squares (PLS) was utilized to analyze the data. Results found in this study support the evidence that surprising negative events enhance knowledge communication effectiveness, but more importantly that the surprise-performance relationship is not a linear function but follows the inverted U shape.
