Abstract
Objectives - This study reported in this article aimed to identify: i) the concerns of the actual research related to the application of the Design for All paradigm in the development of information technology applications to support older adults? ii) the types of applications based on information technology that are being developed according to the Design for All paradigm to support older adults; and iii) the maturity level of these applications. Methods - A systematic review was performed based on a search of the literature. Results - A total of 31 proof-of-concepts prototypes were identified targeting the following application areas: special purpose machines, virtual assistants, social networking, messaging services, intelligent environments, information services and healthcare. Conclusion - Although the studies included in this systematic review present positive impact of the application of the Design of All paradigm, there is a lack of robust trials with strong experimental evidence.

Abstract
Cannabis is the most used illicit substance in Portugal and is the one, which presents, on average, an earlier onset of consumption. Craving is considered one of the fundamental factors linked to the cannabis use, associating anxiety, stress and depression. The sample consisted of 143 individuals from the northern area of the country and the data was gathered through two online questionnaires (DABS-21 and the MCQ-SF). The obtained results allow us to conclude that emotionality, purposefulness and compulsivity are positively associated with the level of craving and, combined, as well to stress and depression. The number of years of consumption presents a significant effect in anxiety, with a medium effect size.

Abstract
A canábis é a substância ilícita mais consumida em Portugal com um início de consumo muito precoce. O craving é considerado um dos factores fundamentais ligados ao consumo de canábis, associando-se à depressão, a ansiedade e ao stresse. Espera-se que nível de craving e sexo se relacionem com a depressão, ansiedade e stresse numa amostra de consumidores portugueses. A amostra foi constituída por 143 consumidores da zona Norte do país e os dados recolhidos através de questionários online (DASS-21 e o MCQ-SF). Os resultados permitem concluir que a emocionalidade, a intencionalidade e a compulsividade relacionaram-se positivamente com o nível do craving, bem como, com o stresse e a depressão. Quanto ao número de anos de consumo, constatou-se um efeito significativo, de dimensão média, na ansiedade.

Abstract
This manuscript aims to present students with a guiding document for the preparation of scientific papers. It aims to overcome a serious oversight in higher education, which is to develop capacities for scientific research and its dissemination, without teaching the students how to write a scientific article.
