Abstract
Digital exposure to the Internet among the younger generations, notwithstanding their digital abilities, has increased and raised the alarm regarding the need to intensify the education on cybersecurity in schools. Understanding of the human factor and its influence on children, namely their attitudes and behaviors online, is pivotal to reinforce their awareness towards cyberattacks, and to promote their digital citizenship. This paper aims to present an integrated cybersecurity and cyberawareness strategy composed of three major steps: (1) Cybersecurity attitude and behavior assessment, (2) self-diagnosis, and (3) teaching/learning activities. The following contributions are made: Two questionnaires to assess risky attitudes and behaviors regarding cybersecurity; a self-diagnosis to measure students' skills on cybersecurity; a lesson plan addressing cyberawareness to be applied on Information and Communications Technology (ICT) and citizenship education curricular units. Cybersecurity risky attitudes and behaviors were evaluated in a junior high school population of 164 students attending the sixth and ninth grades. The assessment focused on two main subjects: To identify the attitudes and behaviors that raise the risk on cybersecurity among the participating students; to characterize the acquired students' cybersecurity and cyberawareness skills. Global and individual scores and the histograms for attitudes and behaviors are presented. The items in which we have observed significant differences between sixth and ninth grades are depicted and quantified by their corresponding p-values obtained through the Mann-Whitney non-parametric test. Regarding the results obtained on the assessment of attitudes and behaviors, although positive, we observed that the attitudes and behaviors in ninth grade students are globally inferior compared to those attained by sixth grade students. The deployed strategy for cyberawareness was applied in a school context; however, the same approach is suitable to be applied in other types of organizations, namely enterprises, healthcare institutions and public sector.

Abstract
—The main objective of this work is to summarize the most commonly used dielectric fluids in the power distribution transformers, as well as to discuss what are the latest and the rationale behind those trends. The favorable and unfavorable reasons for any choice behind each of those dielectric fluids will be discussed. Additionally, this work also advances the power distribution transformers health index most commonly used to assess the condition of the transformer.

Abstract
Despite the current importance of international retirement migration for both academics and practitioners, the extant literature on the topic is still scarce and mostly focused on short-period migration flows from wealthy and northern countries to cheaper and warm-weather destinations. This article aims at shedding light on the role of tourism in prospective migrants' decision-making process, considering the framework provided by the push-pull model, which is often used to explain both migration and tourism. A qualitative study was conducted, comprising ten in-depth interviews with 45+ year-old Brazilian citizens who intend to move to Europe after retirement. Results show that tourism is important for prospective migrants to evaluate possible migration destinations, as some of the most relevant migration pull factors (e.g., safety) are easily assessed during tourism experiences. Participants in this study also carefully plan tourism activities prior to their decision to migrate in order to get a more realistic notion of what the destination is like for residents. Overall, this study demonstrates that tourism is particularly important for several stages of migrants' decision-making process.

Abstract
As supply chains become more digital to reach new levels of global competitiveness, caveats from this decision arise. Cyber-risks are one of these potential setbacks, affecting supply chains directly and indirectly, and propagating via supply chain flows and stocks information, material, and financial. This study applied a systematic literature review to determine how the supply chain's flows and stocks serve as points of entry to cyber-risks. Cyber-risks arise from different sources (i.e., direct attacks, built-in problems, low-quality issues), impacting supply chains' flows and stocks (material and information). There is a relation between the type of supply chain and which flow, or stock facilitates access to the supply chain. Finally, we provide a distinction between two concepts related to Supply Chain Risk Management and cyber-risks. This research is useful to 1) enterprise decision-makers, as the description of potential cyber-risks' points of entry delivers hints on where to focus managerial efforts; 2) developers of Supply Chain Management (SCM) Information and Communication Technology (ICT) systems, since discussing potential points of entry build awareness about probable exploitation points, thus improving ICT systems' resiliency, and 3) scholars, as the depiction of the state-of-the-art may serve as a common departing point for future research.

Abstract
Over the past few years, the amount of information generated, consumed and stored on the Web has grown exponentially, making it impossible for users to keep up to date. Temporal data representation can help in this process by giving documents a sense of organization. Timelines are a natural way to showcase this data, giving users the chance to get familiar with a topic in a shorter amount of time. Despite their importance, little is known about their use in the context of single documents. In this paper, we present Time-Matters, a novel system to automatically explore arbitrary texts through temporal narratives in an interactive fashion that allows users to get insights into the relevant temporal happenings of a story through multiple components, including temporal annotation, storylines or temporal clustering. In contrast to classical timeline multi-document summarization tasks, we focus on performing text summaries of single documents with a temporal lens. This approach may be of interest to a number of providers such as media outlets, for which automatically building a condensed overview of a text is an important issue.

Abstract
In this paper it is presented an educational experiment, that consists of a mechatronic system applied to demonstrate concepts such as prototyping, control, haptic feedback and the use of different sensors and actuators. The described mechatronic system is based on the use of two identical manipulators, being physical devices commonly used in the industry. The physical components of the manipulators were 3D printed, being the original model of each manipulator the EEZYBotArm MK2. This, already existent prototype was modified, with the necessary changes, to fulfill the requisites of the proposed system, being included load cells to provide measurement of the applied forces, and the robot gripper was also modified, being applied an electromagnetic actuator.
