Resumo em Inglês:Abstract Information Technology (IT) governance in small and medium-sized businesses is a subject that still requires more effort. Many of the studies that deal with this subject refer to large companies. IT governance structures, originally developed for the context of large enterprises such as COBIT, ISO/IEC 35800 or ITIL, when applied to the context of small and medium enterprises, lead to undesirable results and failures in the deployment process. The objective of this work was to perform a systematic mapping on IT governance in small and medium enterprises between 2007 and 2017. Systematic mapping studies are useful for categorizing and summarizing the existing information concerning a research question in an unbiased manner. Thus, from an initial set of 63 papers, a total of 17 research papers were selected for the mapping study. The results obtained allowed us to reach conclusions concerning the state-of-the-art of IT governance mechanisms, theories applied in the context and the consequences of IT governance. From the results of this study it was possible to perceive the low use of relational mechanisms of IT governance in the studied context, the constant need to adapt frameworks such as COBIT and ITIL, so that they can adapt to the reality of SMEs, the wide variety of theoretical approaches and the importance, for SMEs, of the concept of IT value for the business.
Resumo em Inglês:Abstract Mobile Payment Services have advanced in the last two decades, gaining the attention of experts and researchers from around the world. A number of reviews and literature analysis studies have been carried out, aimed at analysing the numerous dimensions of mobile payment services; however, no researcher has attempted a co-citation analysis to scrutinise and comprehend the core knowledge structures that are integral parts of mobile payment services studies. Therefore, in order to fill this research gap, this research article aims to interpret the corpus of mobile payment services research, which was published during the period of 1997 to June 2017. Bibliometric and Social Network Analysis (SNA) methods were employed to formulate the core intellectual structure of research targeting mobile payment services. The Web of Knowledge (WoK) database was the key source from where 406 articles and 3,424 citations were obtained. These documents were analysed using co-citation analysis. UCINET was used to enlist the keynote research papers in the realm of mobile payment services as per factor analysis, citation and co-citation analysis, multidimensional scaling and centrality measurement. Seven core clusters of mobile payment services research emerged as a critical finding of this study; these clusters include (1) Adoption and usage; (2) Trust, risk and security; (3) Application; (4) Scheme; (5) Protocol; (6) Architecture; (7) Mobile payment corporation. The findings of this research study provide crucial guidelines for practitioners and researchers involved in this field.
Resumo em Inglês:ABSTRACT The word “Smart Cities” is the buzzword in every corner of the world. Many countries across the continents are trying to plant new smart cities or in the conversion process of existing cities. Bali (Indonesia) also seems to be in a conversion process of its Brown Field Cities. This research manuscript attempts to explore the Bali (Island) as a Smart Island regarding Smart Environment, Smart Economy, Smart Governance, Smart Mobility, Smart Living and Smart People dimensional perspective. This research manuscript has adopted a triangulation method for thematic narration since the study is qualitative and case study. The study explored that Bali/Balinese cities is/are still baby stepping of smart cities plantations. There needs to be lot of work has to be done to become Smart Bali Island. The findings will help the Bali government to understand how far they could become full-fledged Smart Island by providing the Quality of Life to citizens and economic development.
Resumo em Inglês:ABSTRACT Although big data has become an integral part of businesses and society, there is still concern about the quality aspects of big data. Past research has focused on identifying various dimensions of big data. However, the research is scattered and there is a need to synthesize the ever involving phenomenon of big data. This research aims at providing a systematic literature review of the quality dimension of big data. Based on a review of 17 articles from academic research, we have presented a set of key quality dimensions of big data.

Resumo em Português:Resumo Nessa pesquisa exploratória objetiva-se construir um modelo que subsidie o processo de desenvolvimento de software para avaliar um sistema de gestão. Utilizou-se a Metodologia Multicritério de Apoio à Decisão - Construtivista (MCDA-C), a qual identifica, organiza e mensura, ordinal e cardinalmente, os aspectos tidos em conta pelo decisor para a gestão do contexto. Confirma-se a possibilidade de construção de um modelo que explicite os requisitos do cliente, visando avaliar o grau de atendimento que o software proposto, denominado Monitoring and Improving Context (MIC), alcança, e assim ser utilizado como instrumento de negociação para a definição do sistema necessário.
Resumo em Inglês:Abstract The aim of this exploratory research is to construct a model to support a process of software development in order to evaluate a management system. The Multicriteria Methodology of Decision Aiding - Constructivist (MCDA-C) was used, which supports the identification, organization and ordinal and cardinal measurement of the aspects taken into account by the decision maker for the context management. We argue that it is possible to construct a model with the specification of the customer requirements to evaluate the degree of service that the proposed software named Monitoring and Improving Context (MIC) achieves in relation to the demands of the customer, and thus be used as an instrument for the definition of the final system.
Resumo em Inglês:ABSTRACT This study aimed to investigate the relationship between accounting students’ performance and sociodemographic variables (namely gender, employment, marital status, and ethnicity) in distance education. I collected data from the 2015 National Exam of Students’ Performance, obtaining a final sample of 11,707 observations. Results indicated that male students outperformed female ones. Also, worker students have better performance than their colleagues. Married students obtained better performance than their single colleagues, but no relevant difference was found in comparison to other (divorced, widowed, etc.) students. Regarding ethnicity, white students outperformed other students (black, brown, and others).
Resumo em Inglês:Abstract In this paper, we argue that the ongoing processes of datafication and dataism are constraining initiatives to construct open data portals contributing to inter- and transdisciplinary research. The former overvalues quantitative data, whereas the latter reinforces the belief that ‘raw data’ is neutral and apolitical, ignoring how data is processed. Based on the case study of an open data portal being developed at an inter- and transdisciplinary research institute, we argue that datafication and dataism are highly problematic trends, because they marginalize qualitative data employed in critical, constructivist, and other interpretive methods, thereby limiting the possibility of complementing and extending each other. Nonetheless, we also maintain that these trends are not technologically determined but are modifiable, based on the design of data portals. Accordingly, we conclude by offering suggestions for constructing data portals, such as opening up the design process and democratizing standards.
Resumo em Inglês:Abstract Trust plays a vital role in the adoption of a new payment system in so far as people need to trust that the prevailing currency, or in other words, money, is recognised by all stakeholders. With the evolution of the payment methods, shifting from paper-based to electronic-based, building consumer trust has become a vital element for the success of businesses involved in the mobile payment systems sector. In this context, the aim of this study was to delve deeper into the factors that have impact on consumers trust in mobile payment systems (MPS) in Australia. A quantitative approach through a questionnaire survey was conducted to measure the data collected. The data of 200 participants were gathered using SurveyMonkey and the Excel spreadsheets was imported into SPSS (Statistical Package for the Social Sciences) system, where the data were organised. Besides, this study adopted the Partial Least Square Structural Equation Modeling (PLS-SEM), where the data analysis took place. The findings of PLS-SEM analysis pointed out that behavioural factors and organisational factors have significant impact on consumers’ trust, and this, as a consequence, have influence on MPS adoption. On the other hand, this research found that the technological factors, governmental factors and personal factors have no significant impact on Australian consumers’ trust and this, as a result, has no influence on MPS adoption.
