Enhance knowledge communication and learning: a surprise paradox
Full text linkHuman-computer interface is a pivotal factor that can promote or deter the effectiveness of Web-based knowledge communication. 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
Towards classifying sociocultural aspects in global software development
Full text linkThe geographical, temporal distances and socio-cultural differences are the biggest challenges for Global Software Development (GSD). In GSD, it is necessary to deal with behaviors, values and skills of the team members, conflicts, rework, delays, etc. can influence a software production process. The objective of this paper is to identify the sociocultural aspects and propose a classification structure under different analytical perspectives in order to offer adequate support to the management of GSD teams. A systematic mapping and proposal an approach that classifies aspects in three perspectives: collaboration, people and external. The analysis allows the project manager to make decisions about the performance of human resources and mitigate problems arising from communication, cooperation and coordination, generating better results in indicators of productivity, quality and efficiency of GSD teams
A Mapping Study of scientific merit of papers, which subject are web applications test techniques, considering their validity threats
Full text linkProgress in software engineering requires (1) more empirical studies of quality, (2) increased focus on synthesizing evidence, (3) more theories to be built and tested, and (4) the validity of the experiment is directly related with the level of confidence in the process of experimental investigation. This paper presents the results of a qualitative and quantitative classification of the threats to the validity of software engineering experiments comprising a total of 92 articles published in the period 2001-2015, dealing with software testing of Web applications. Our results show that 29.4% of the analyzed articles do not mention any threats to validity, 44.2% do it briefly, and 14% do it judiciously; that leaves a question: these studies have scientific value
Information Systems supporting the functions of organizational memory: An exploratory study
Full text linkCom este artigo, analisou-se como os Sistemas de Informação (SI) disponíveis nas organizações podem apoiar as funções da Memória Organizacional (MO). 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.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
Artificial Intelligence: way forward for India
Full text linkArtificial Intelligence (AI) is likely to transform the way we live and work. 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
Methodology for The Development of an Ontology Network on The Brazilian National System for the Evaluation of higher Education (OntoSINAES)
Full text linkOntologies occupy a central position in any conceptual model of the Semantic Web, aiming fundamentally to add explicit semantics to the contents available in the Web. 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

DEVELOPERS VIEWS ON INFORMATION SYSTEMS QUALITY AND SUCCESS IN CANADIAN SOFTWARE DEVELOPMENT FIRMS
Full text linkFor years software developers have struggled in their attempts to deliver high quality and successful software products. A survey was conducted in Canada to assess the main determinants of information systems (IS) quality and success. The survey confirmed the notion that developer skills and contribution had the greatest impact on information systems quality, over process maturity and the application of the latest technology. The survey also discovered that user perception had a greater impact on IS success in comparison to IS quality. In an attempt to gain deeper insights into the state of IS quality and success in Canada, interviews were conducted with Canadian software developers. The interviews revealed that organization climate such as top management support, the social interactions and dynamics among project team members and the structural analysis of the industry are other factors which can influence the quality and success of the delivered software product. These insights if applied during the development and delivery of information systems can enhance the likelihood of producing high quality and successful software products and increase the competitiveness of these firms
