- Acceptance and familiarization with wearable devices in Portugal and BrazilPublication . Lopes, Isabel Maria; Rocha, João; Oliveira, PedroThis research sought to understand the acceptance of wearable devices in Portugal and Brazil, analyzing aspects such as demographic profiles, experiences with technology and personal perceptions. An adaptation of the UTAUT2 model was made, obtaining responses from university students and frequent internet users through a questionnaire that used the Likert scale. The evaluation of the data indicated a predominance of participants from Portugal, a tendency for acceptance to be more pronounced among younger people, those with a higher level of education and a greater technological proficiency among men and more qualified individuals. The relationship between users and non-users of wearable devices proved to be balanced, with a more marked acceptance by people aged 35 to 59, women and those who have a positive view of technology. The Smartwatch stood out among the devices, followed by the Fitness Bracelet and the Smart Ring. A variation in social influence was observed according to the type of device, being more striking in the case of Smartwatches. Surprisingly, social influence did not prove to be as crucial in the acceptance of wearable devices as initially thought. The findings show a trend towards the adoption of these devices, while also warning of challenges linked to the perceived value and price of products, signaling an area with great potential for future research and innovation.

- Adoption of an information systems security policy in small and medium sized enterprisesPublication . Lopes, Isabel Maria; Oliveira, PedroInformation Systems Security (ISS) is a relevant fact for current organizations. This paper focuses on Small and Medium Sized Enterprises (SMEs). This article aims to constitute an empirical study on the applicability of the Action Research (AR) method in information systems, more specifically by assessing the adoption of an ISS policy in six SMEs, and identifying the critical success factors in adopting an ISS policy. The research question we intend to answer is to what extent this research method is adequate to reach the proposed goal. The results of the study suggest that AR is a promising means for the evaluation of ISS policies adoption. It can both act as a research method that improves the understanding about the reasons why the policy has been abandoned, and as a change method, assisting practitioners to overcome barriers and suggesting measures to be implemented.
- Adoption of wearables: a UTAUT2 perspectivePublication . Lopes, Isabel Lopes; Oliveira, PedroThis research sought to understand the adoption of Wearable devices, analyzing aspects such as demographic profiles, experiences with technology and personal perceptions. An adaptation of the UTAUT2 model was made, obtaining responses from university students and frequent internet users through a survey using the Likert scale questions was administered to 96 participants. Based on the analysis, there was a tendency for higher acceptance among younger people, those with higher levels of education and greater technological proficiency among men and more qualified individuals. The Smartwatch stood out among the devices, followed by the Fitness Bracelet and the Smart Ring. A variation in social influence was observed according to the type of apparatus. Unexpectedly, social influence has not proven to be as crucial in the acceptance of wearable devices as initially thought. The results show a trend towards the adoption of these devices, while also warning of challenges linked to the perceived value and price of products.
- Aplicabilidade do regulamento geral sobre proteção de dados em clínicas de saúdePublication . Lopes, Isabel Maria; Oliveira, PedroO Regulamento Geral sobre Proteção de Dados (RGPD) visa assegurar a coerência da proteção das pessoas singulares no seio da União Europeia (UE). O RGPD compreende regras inovadoras muito importantes que serão aplicadas em toda a UE e afetarão de forma direta todos os Estados Membros. Além disso, o seu objetivo é superar os regulamentos fragmentados existentes e modernizar os princípios da privacidade na UE. É já em maio de 2018 que este regulamento entra em vigor, trazendo consigo vários desafios tanto aos cidadãos, como às empresas e outras organizações privadas e públicas. A proteção de dados pessoais é um direito fundamental. O RGPD considera uma “categoria especial de dados pessoais” e inclui aqui os dados relativos à saúde, pois são dados pessoais sensíveis, sujeitos, por isso, a especiais reservas quanto ao seu tratamento e acesso por terceiros. Dada esta premissa é aqui que este trabalho se vai debruçar, analisando a aplicabilidade do RGPD em clínicas de saúde em Portugal. Os resultados são discutidos á luz dos dados recolhidos através de um inquérito e identificados trabalhos futuros.
- Applying action research in the formulation of information security policiesPublication . Lopes, Isabel Maria; Oliveira, PedroInformation Systems Security (ISS) is crucial in all and each of the services provided by organizations. This paper focuses on Small and Medium Sized Enterprises (SMEs) as although all organizations have their own requirements as far as information security is concerned, SMEs offer one of the most interesting cases for studying the issue of information security policies. Within the organizational universe, SMEs assume a unique relevance due to their high number, which makes information security efficiency a crucial issue. There are several measures which can be implemented in order to ensure the effective protection of information assets, among which the adoption of ISS policies stands out. This article aims to constitute an empirical study on the applicability of the Action Research (AR) method in information systems, more specifically through the formulation of an ISS policy in SMEs. The research question is to what extent this research method is adequate to reach the proposed goal.
- Architecture of information security policies: a content analysisPublication . Lopes, Isabel Maria; Oliveira, PedroThe growing importance that Information Systems (IS) have in our companies naturally brings about a need to rely and trust in their use. There are a number of technologies which help ensure the security and trust in the IS use. However, technology alone does not solve all the problems, which is why there is a need for well-defined information systems security policies in order to ensure the data integrity and confidentiality. Nevertheless, there is a lack of information concerning the contents that such policies must have. This work aims to contribute to the filling of this gap. It presents a synthesis of the literature on information security policies content and it characterizes 15 Small and Medium Sized Enterprises (SMEs) information security policy documents as far as their features and components are concerned. The content analysis (CA) research technique was applied to characterize the information security policies. The profile of the policies is presented and discussed and propositions are made for possible future works.
- Boas práticas agroecológicas em horticultura urbanaPublication . Peixinho, Diana; Rodrigues, M.A.; Nobre, Sílvia; Oliveira, PedroA agricultura urbana é um fenómeno generalizado em todo o mundo. Nas grandes cidades dos países em desenvolvimento e em épocas de crise económica nos países desenvolvidos, a criação de espaços para agricultura urbana tem sido um instrumento político de grande valor social que permite aumentar a segurança alimentar e mitigar a pobreza e o desemprego. Recentemente, têm surgido projetos de agricultura urbana em cidades de países desenvolvidos destinados a assegurar atividade social e qualidade de vida aos seus cidadãos. São espaços de convívio, desporto e lazer, onde as pessoas relaxam do stresse acumulado de um dia de trabalho. No final do dia, ainda levam para casa os vegetais que eles próprios cultivaram. A Associação Cultural e Recreativa do Pessoal do Instituto Politécnico de Bragança (IPB) desenvolve, desde 2011, um projeto de hortas sociais inicialmente dirigido à comunidade académica mas que rapidamente se generalizou à vizinhança do campus politécnico. Neste trabalho relatam-se algumas práticas com elevado significado agroecológico adotadas pelos horticultores. A fertilização orgânica está generalizada. Usam estrume de bovino disponibilizado pela instituição. A cinza é outro tipo de fertilizante muito utilizado que os horticultores trazem de casa e usam em culturas de inverno, em particular o alho. Diversos horticultores estão a compostar os resíduos das culturas para usar como fertilizantes. O mulching, seja com estrume, palha ou plástico é também uma prática corrente. É usado para reduzir a formação de crostas e favorecer a emergência das sementeiras de primavera, no controlo de infestantes e como proteção contra pássaros. Ointercropping é uma prática que permite maximizar a utilização do recurso solo, cultivando mais que uma cultura no mesmo espaço e tempo. A espécie mais frequentemente envolvida é a alface, devido ao seu ciclo cultural muito rápido, ocupando o terreno apenas na fase inicial do ciclo biológico de uma outra cultura de ciclo mais longo. As pessoas estão a usar sementes que trazem das aldeias de onde são originárias, assumindo um papel importante na preservação de recursos genéticos vegetais. Para além destas, muitas outras práticas ecologicamente relevantes têm sido adotadas. Em acréscimo, o projeto de horticultura urbana do IPB tem-se revelado de elevada importância na formação e sensibilização para os valores ambientais.

- Can a small city be considered a smart city?Publication . Lopes, Isabel Maria; Oliveira, PedroThe term “smart cities” has been widely used over the last years. The main goal of the smart cities initiative is to enable cities to manage their assets efficiently, investing in innovation and creativity as a way to promote sustainable and inclusive urban development. When tackling such an emerging and promising area, it is important to know whether all cities can be fitted into this concept regardless of their size or location, thus promoting social equity throughout the whole territory. The Portuguese Smart Cities Network includes 46 municipalities throughout the national territory. There are a lower number of such cities located in the interior part of the country. This was one of the reasons leading to this research work aiming to find out whether a small/medium inland city can be considered a smart city. There are a number of measures of action that a city can explore in order to be considered a smart city. Considering the place under study, the aims of this research work are to ascertain what measures are being adopted to increase the efficiency of the city’s resources and services management and to what extent it can be considered a smart city
