Email Analysis in Fraud Investigation: Digital Forensic and Network Analysis Approach

Email is an imperative method of communication that is changing the way people share their data and information. It provides effective and efficient communication, especially in business, convenience, and easy access and replication. Those electronic data should be considered by a fraud investigator to comprehend the investigation. Email can be divided into two parts: the head of the email and the email body. The head of the email is metadata that consists of unstructured data, and the body and its attachment consist of semi-structured data. The email data usually comes in large volumes and ranges of types. Therefore, a manual investigation of an email should be avoided. This paper uses the Design Science Research Methodology to discover the most profound framework in an email fraud investigation. Using email metadata and email body, this research performs a digital forensic framework: preparation, gathering, processing, and presentation, combines with social network analysis to be applicable in the investigation. The result shows that digital forensics process, network analysis, data visualization provides a more valuable and comprehensive insight into email analysis.

GAMIEFECTS: A proposta de um framework para apoiar a avaliação de gamificação em contextos educacionais

Na educação, a gamificação tem se mostrado uma estratégia promissora para promover o aprendizado, a motivação e o engajamento dos alunos. Entretanto, alguns estudos têm mostrado que seu uso nem sempre traz resultados positivos, sendo imprescindível considerar o processo de avaliação um aspecto importante, uma vez que a partir dela é possível verificar a eficácia da gamificação e se os objetivos da gamificação estão sendo alcançados. Nesse contexto, verificou-se a escassez de métodos ou abordagens avaliativas específicas para a gamificação, resultando na falta de instruções e orientações para a realização desse procedimento. Assim, este trabalho trata-se de parte de uma dissertação em fase desenvolvimento, e apresenta um framework para apoiar o processo de avaliação da gamificação em contextos educacionais. O framework GAMIEFECTS foi desenvolvido com base no Design Science Research Methodology (DSRM) e é composto por cinco dimensões, onde cada uma delas corresponde a um determinado aspecto de avaliação e deve ser capaz de auxiliar professores, pesquisadores e/ou designers com processos avaliativos que envolvem o uso da gamificação para contextos de aprendizagem.

Smart Sustainable City Roadmap as a Tool for Addressing Sustainability Challenges and Building Governance Capacity

Building smart sustainable cities initiatives requires governance capacity, which is constantly challenged by a diversity of actors and the transformation towards a digital society; however, the process of identifying the conditions for building a smart sustainable city (SSC) is not straightforward. As an attempt to map the key governance conditions, the goal of this study is to suggest guidelines for the development of SSC initiatives in the format of a generic roadmap. This research applies design science research methodology and builds the roadmap based on identified antecedents that may hinder or facilitate the development of SSC initiatives from a systematic literature review and the analysis of key governance aspects from 12 smart city initiatives in Europe and Latin America. This paper builds its results through a four-step approach including: (1) defining the main concepts and dimensions within the smart sustainable city context; (2) identifying sustainability challenges for the development of smart sustainable city initiatives; (3) analysing key governance aspects from smart sustainable city initiatives; and (4) designing an actionable research-based roadmap and practical recommendations. The resulting roadmap contains 11 key governance conditions for developing strategies for smart sustainable city initiatives that were classified into three main phases: (1) planning; (2) implementing; and (3) adopting, monitoring, and evaluating. In terms of contribution, this research provides a tool to support the development of initiatives, addressing sustainability challenges and strengthening governance capacity to ensure the long-term impacts of smart sustainable cities.

Exploration of practitioner experiences of flexibility and transparency to improve BIM-based model checking systems

The use of BIM-based Model Checking (BMC) has the potential to improve building design processes by enabling the automation of building assessments. However, only a few BMC systems are being used in the building design practices. The limited use has been identified to be related to socio-technical challenges that have so far not received much attention in research regarding BMC systems. To explore these challenges, a Design Science Research methodology was used to design a BMC prototype to improve the socio-technical challenges of BMC systems, specifically challenges of transparency and flexibility. The prototype was tested with practitioners to investigate aspects of BMC systems that potentially hinder its use. The results were used to discuss the potential for more practical application of BMC systems in design practices to obtain the benefits of providing a faster, more consistent, and more precise assessment of buildings.

Students' perceptions of academic performance in Distance Education evaluated by Learning Analytics and Ontologies

Keeping track of student learning progress in the Distance Education it is a challenge for education specialists because it is always not possible to adopt the same evaluation mechanisms as traditional education due to transactional distance between educators and students. To help educators in the process of evaluating the acquisition of skills and monitoring students' learning experiences, we present the SapeS architecture, which uses Learning Analytics and Ontologies to produce information about student performance. This architecture enables both educators and students to intervene in the teaching process and promotes autonomy to students successfully achieve their planned objectives. This proposal was based on the Design Science Research methodology, which enables the production and evaluation of the proposed solution to better understand its viability in the participant's real context.
