Abstract
A number of events may negatively affect one's holidays abroad - problems while travelling, or problems with national cultures. National culture may have a big impact on holiday experiences, and so needs to be understood by tourists in order for them to have a more memorable time when on holiday abroad. If treated badly, or with contempt, tourists may be more forgiving if they realize and understand that they are in the presence of more ethnocentric and masculine cultures. If treated well, tourists may appreciate this even more if it goes contrary to national values and with regards to how foreigners are normally treated in that location. Important is that tourists do not seek confrontation with less-forgiving and more power-distant cultures, such as the Chinese. This is an auto-ethnographic account of a family on an annual holiday abroad, for leisure purposes. Auto-ethnography is used to analyze certain situations which occurred during the Summer holidays of 2017, with the lead author and his family while on a trip from Portugal to Australia, passing through Spain on the way out and Hong Kong and the UK on the way back. Despite very memorable experiences, problems with the deadly Typhoon Hato and the Tropical Cyclone Pakhar resulted in a degree of apprehension by the lead-author and his family and a desire to stay at home for an indefinite period, before going on holiday (to far-away places) again. So, despite a need for an innovative experience while on holiday, certain negative occurrences (or life-changing experiences) may act against similar trips happening in the future. Being more culturally aware may result from a training scheme or a communication program - which may be undertaken at the national level. Finally, let it be stated that examples of welcoming people, as well as the opposite, were found in Spain, Australia, and Hong Kong. While this research seeks to show certain prevalent characteristics of national cultures, there will always be exceptions and so travellers should keep an open mind.

Abstract
The Internet of Things (IoT) is a new model that integrates physical objects and Internet and became one of the principal technological evolutions of computing. It is estimated that a trillion of physical objects will be connected to the Internet until 2022. The low accessibility and the lack of interoperability of many of these devices in a vast heterogenous landscape will make it very hard to design specific security measures and apply specific security mechanism. Moreover, IoT networks still exposed and vulnerable to attacks aimed to disrupt the network. Therefore, additional security tools specific to IoT are needed. Intrusion Detection System (IDS) could fulfill this purpose. In this paper, we present a literature review on the IDS in IoT topic, mainly focusing on the current state of research by examining the literature, identifying current trends and presenting open issues and future directions.

Abstract
Students are getting better over time but perhaps it is, at the same time, getting ever more difficult to capture their attention in class, especially as regards research and research methodology. The Business Narrative Modelling Language (BNML) has been used (Oliveira and Ferreira, 2011; Goncalves et al., 2013; Au-Yong-Oliveira et al., 2015; Goncalves et al., 2016) to portray and discuss research findings. With qualitative research, in particular, the research process may be more transparent, more objective and faster by following the rules of BNML. Throughout the first semester for 2017-18, and on a Strategy and Competitiveness course, at the master's level, the advantages of BNML were shown on several occasions. Students were required to present what was for most of them their first research case study. BNML uses both the narrative and pictorial representations to showcase and highlight research results. In the age of the smartphone, icons and emojis, students respond well to pictorial representations. However, on the other hand, one has to acknowledge that children go from doing drawings to represent everything in their lives to unexpectedly stopping giving drawings to their parents and siblings and friends on all occasions - including for Christmas and for birthdays. Therefore, it is still a challenge to get adult students to understand BNML, especially in large classes. What is still lacking is a handbook on how to use BNML - despite the existence of a number of publications on the topic. This article thus seeks to shed further light on this research tool. Sharper master's students, doing a dissertation and one-on-one with the lecturer, quickly comprehend and grasp the essence of BNML and its use of key words and game patterns to tell the research case story, over time. Movement and colour and emotion may all be seen in BNML - which remains intuitive, and thus true to qualitative and interpretive research. In Portugal, qualitative research is still not seen, by many researchers, to be a serious research method, especially by the more conservative of researchers, who favour the use of statistics and thus of "more scientific" quantitative research methods in management research. We hope to contribute to a change of mind-set with our article.

Abstract
The legislation on the accessibility of the information and communication technologies (ICT) is not new and consequently there have been a number of international and national initiatives, however they are very focus in the Web. We are in the threshold of a more comprehensive approach in the ICT domain. The European Standard EN 301 549 specifies the accessibility requirements for public procurement of ICT products and services in Europe. This study focuses on the analysis of the benefits / impact, for each group of People with Special Needs (PSN), the parameters of the European Norms (EN) for ICT products and services, which support the new legislation in the domain of public acquisition for the countries of the European Union (EU), the EU Public Procurement Directive 2014/24/EU. Questions related to methodologies, techniques and tools to evaluate the parameters of these EN will be studied in the future, as well as the models for the certification of ICT products and services, with the purpose of presenting solutions. In the future, a framework will be also designed and developed with specific functionalities and being capable of assist and facilitate the evaluation of EN parameters, and consequently the certification of the ICT products and services.

Abstract
Cognitive theorists believe that the learning process involves the integration of events into actives organizational structures termed schemata. Schemata serve a number of functions in human cognition: schemata regulates attention, organizes searches of the environment and “fill the gaps” during information processing. Thus, the mind uses schemata to selectively organize and processes all the information individuals receive from the world. This perspective fits e.g. in teaching blind and deaf people alongside of children with special education needs. The aim of the research developed until the moment was to prove that the full integration of the concept of teaching and learning in the light of cognitive theories. © Springer International Publishing AG 2018.
