Abstract
The aim of this article is to show how autoethnography is a useful and revealing research methodology that should be encouraged in academia, especially in higher education. With objectivity, autoethnography, which is a relatively new approach, may be a path toward deeper cultural discussions that are so important in everyday life. Moreover, autoethnography leads to important reflexive and critical observations made by students. Autoethnography is a readily accessible, low-cost methodology and thus very appealing to students and younger researchers. With this article, the author exemplifies autoethnographic accounts and narrates three different stories that occurred while trekking with three different trekking guides in Patagonia (El Chalten), Argentina. Argentinian culture, in South America, is the focus. Researchers need to be careful of misleading statements in the literature, such as that in Argentina modesty is apparently not tolerated. We found that two of our guides and leaders - Mariano and Liz - both had modest (and pleasant) demeanors. Hence, we conclude that it is important to maintain an open mind and resist categorizing people. This is a vital point of cultural studies that is often not taken seriously. Cultures are made up of individuals and thus many differences can be found in the midst of an attempted standardization, and the desire to put everyone in the same "basket".

Abstract
In this age of technology, information, innovation, and so many other features that could be associated with it, it becomes necessary to review the benefits and risks associated with this change. The question that guides this article is: Does the easiness granted to us, through the many online mechanisms, affect our ability to perceive at the moment of making a purchase decision? Rather, from a financial perspective, is the quick and easy way that the internet allows the consumer to make a payment influencing the consumers' buying act? Through the analysis of various mobile applications available for the aforementioned purpose, as well as a survey, that featured 137 answers from various age groups and occupations, we will present a brief conclusion about this theme, aiming to contribute to a better and broader understanding of the benefits, risks, advantages and disadvantages of these so well-known banking applications that increasingly stand out in the daily lives of the Portuguese. The results of this exploratory study reveal the importance of a greater and better instruction when using these innovative tools, so the user can stop being merely a hostage to their risks and begin to fully enjoy the benefits.

Abstract
With the increasing use of smartphones in people's daily lives, mobile accessibility has become a key factor for them. Tourism is one of the sectors that has benefited the most from this growth but has not yet reached its full potential as accessibility has not yet been fully exploited. The main goal of this study is to assess accessibility in mobile applications for the tourism sector. Thus, 14 mobile applications were analyzed, using a manual and automatic methodology through the proposal of an evaluation model divided by quantitative and qualitative requirements, as well as the use of features such as VoiceOver and TalkBack. The results show a high overall number of errors in most quantitative requirements as well as non-compliance with most qualitative requirements. On iPhone 4, "Viseu - Guia da Cidade" was the application with the highest rating, while on Wiko GOA, it was the "JiTT.Travel Funchal" application. In turn, on iPhone 6 Plus, iPhone XR, Nokia 5.1 and OnePlus 6 devices, the best results were achieved by the "Viseu - Guia da Cidade," "JiTT.Travel Funchal" and "TUR4all" applications. Regarding the accessibility of mobile applications on different versions of the same mobile operating system, it was concluded that there are no differences in their accessibility on both operating systems (iOS and Android). Finally, regarding the accessibility of applications on smartphones with different screen sizes, there are also no differences in their accessibility.

Abstract
As information systems and technologies grow in usage in the agri-food industry, the same has happened to the relevance of Information Systems (IS) that allow for a parallel control, monitoring and management of the organizations' activities and business processes. As the literature proves, the benefits of implementing adequate and interoperable IS are very numerous and tend to represent a significant determinant regarding the organizations' overall success. Despite this, to the best of our knowledge there currently is no IS architecture designed to serve the specificities of the agri-food industry. With this study a novel information systems architecture for the agri-food sector is proposed. The artefact is composed by 12 integrated main components and a set of subcomponents aimed at supporting all the monitoring, control and management activities. In order to validate the proposed architecture a case study was implemented at a mushroom production organization. This allowed us to perceive the ability of our artefact to serve as the basis for the development of IS that address all of the organization's business and environmental needs.

Abstract
The motivation to perform this particular research comes from a need which we feel exists for further research in this area. It is necessary to answer a set of questions both empirical (observed over the years in the area of health and safety) and theoretical (following an analysis of the international literature) relative to the dimension of the problem of musculoskeletal injuries resulting from the exercise of the nursing profession in a hospital context. Research questions addressed include: 1) Are there complaints associated to the performing of nursing tasks? 2) How serious in terms of absolute numbers are musculoskeletal injuries? 3) What sort of influence does the environment (namely buildings) play, as well as technology / equipment, and work organization? Furthermore, 4) What should be present in the workplace but is not? After analyzing survey (of 168 active nurses in Portuguese hospitals) and interview data and having observed nurses at work, accompanying them in their day-to-day tasks, there is a global tendency to consider that, over the last twelve months of work, in a hospital context, nursing professionals have felt pain or musculoskeletal discomfort in a part of their bodies. Research results point also to more training and more adequate working spaces being needed in order to decrease musculoskeletal injuries amongst nurses. Furthermore, the more widespread usage of technological means which are lacking in some hospitals (such as beds with adjustable height, trapeze-type supporting bars attached above beds, patient transferring lifts and transferring belts) or in bad condition (such as wheels on beds, wheelchairs, and stretchers, which makes moving patients difficult) could also reveal itself to be an important aid, presenting itself as a solution to the problem discussed herein, on the one hand due to the number of injuries on the other due to the need for more professionals.
