- Artificial Intelligence Research and Its Contributions to the European Union’s Political Governance: Comparative Study between Member StatesPublication . Reis, João; Santo, Paula; Melão, NunoIn the last six decades, many advances have been made in the field of artificial intelligence (AI). Bearing in mind that AI technologies are influencing societies and political systems di erently, it can be useful to understand what are the common issues between similar states in the European Union and how these political systems can collaborate with each other, seeking synergies, finding opportunities and saving costs. Therefore, we carried out an exploratory research among similar states of the European Union, in terms of scientific research in areas of AI technologies, namely: Portugal, Greece, Austria, Belgium and Sweden. A key finding of this research is that intelligent decision support systems (IDSS) are essential for the political decision-making process, since politics normally deals with complex and multifaceted decisions, which involve trade-o s between di erent stakeholders. As public health is becoming increasingly relevant in the field of the European Union, the IDSSs can provide relevant contributions, as it may allow sharing critical information and assist in the political decision-making process, especially in response to crisis situations.
- Caracterização do Teatro de Operações de Moçambique entre 1964 -1975Publication . Mesquita, Artur; Pinto, Alberto; Mataloto, Luís; Souto, João; Reis, JoãoApós o final da 2ª Guerra Mundial e o consequente rearranjo de poderes na ordem internacional verificou-se a emergência progressiva de movimentos de autodeterminação claramente antagónicos à ordem colonial previamente estabelecida com especial incidência em África e na Ásia. Neste contexto, Portugal viu-se envolvido na “Guerra do Ultramar”, que se desenvolveu em paralelo com conflitos de características semelhantes que ocorreram em três Teatros de Operações (TO), nomeadamente Angola, Guiné-Bissau e Moçambique. O presente trabalho académico pretende efetuar uma breve caracterização do teatro de operações de Moçambique de 1964 a 1975. São objetivos deste trabalho a caracterização de elementos da geografia física, geografia humana e geopolíticos relevantes para a caracterização do conflito no território moçambicano de 1964 a 1975. Assim como a caracterização dos diversos movimentos insurgentes e a sua evolução, em termos de base ideológica, apoios externos, linhas de comunicações, capacidade militar, modus operandi e da sua relação com a população. O estudo desta temática incidiu na pesquisa de publicações doutrinárias do Exército, bem como de bibliografia publicada por historiadores do tema. Permitindo enquadrar os dados históricos disponíveis nos instrumentos metodológicos utilizados como modelo de análise do IPB em operações de estabilização descrito no PDE 2-09-00 (Exército Português, 2010). Abstract: After the end of the II World War and the consequent reshuffling of the world powers there was a progressive emergence of self-determination movements specifically in Africa and Asia that clearly were antagonist to the previously instated colonialist order. Portugal, in this context, was engaged in the “Colonial Wars” that developed in tandem three conflicts with similar characteristics but fought at different Operation Theatres (OT), namely in Angola, Guinea-Bissau and Mozambique. The present academic paper intends to produce a brief characterization of the Mozambican Operation Theater between 1964 and 1975. This document´ objectives are the characterization of Mozambique´ physical geography, human geography and relevant geopolitical structures that contribute towards the description of the conflict that occurred in the Mozambican territory between 1964 and 1975. As well as the description of the diverse insurgent movements in their respective evolution, ideological base line, modus operandi and their relations with the local populations. The research was framed by the Portuguese Army Doctrinal Publications and the bibliographical survey of available papers and documents published by historians. The collected observations enabled the examination of the historical data based on the modern methodological military operational models of Intelligence Preparation of the Battlefield (IPB) in stabilization operations, as per described in the PDE 2-09-00 (Portuguese Army, 2010).
- Characterisation of Cannabis-Based Products Marketed for Medical and Non-Medical Use Purchased in PortugalPublication . Pires, Bruno; Oliveira, Patrik; Simão, Ana Y.; Reis, João; Ramos, Sofia; Duarte, Ana Paula; Margalho, Cláudia; Rosado, Tiago; Barroso, Mário; Gallardo, EugeniaCannabis-based products have gained attention in recent years for their perceived therapeutic benefits (with cannabinoids such as THC and CBD) and widespread availability. However, these products often lack accurate labelling regarding their cannabinoid content. Our study, conducted with products available in Portugal, revealed significant discrepancies between label claims and actual cannabinoid compositions. A fully validated method was developed for the characterisation of different products acquired from pharmacies and street shops (beverages, herbal samples, oils, and cosmetic products) using high-performance liquid chromatography coupled with a diode array detector. Linearity ranged from 0.4 to 100 µg/mL (0.04–10 µg/mg) (THC, 8-THC, CBD, CBG, CBDA, CBGA), 0.1–100 µg/mL (0.01–10 µg/mg) (CBN), 0.4–250 µg/mL (0.04–25 µg/mg) (THCA-A), and 0.8–100 µg/mL (0.08–10 µg/mg) (CBCA). Among sampled beverages, none contained detectable cannabinoids, despite suggestive packaging. Similarly, oils often differed from the declared cannabinoid compositions, with some containing significantly higher CBD concentrations than labelled. These inconsistencies raise serious concerns regarding consumer safety and informed decision-making. Moreover, our findings underscore the need for stringent regulation and standardised testing protocols to ensure the accuracy and safety of cannabis-based products.
- Complex auditory musical hallucinations with ambivalent feelingsPublication . Canas-Simião, Hugo; Nascimento, Sandra Teles; Reis, João; Freitas, CarinaA 78-year-old woman with hypertension, diabetes mellitus type 2 and bilateral sensorineural hearing loss was referenced to geriatric psychiatry consultation. She presented cognitive dysfunction, erotomanic delusion and complex musical hallucinations (MH), described as hearing her neighbour singing a familiar church song along with bells in the background, making comments and talking to her. A computed tomography (CT) of the brain detected small right nucleocapsular and bilateral external capsules hypodensities of presumed vascular aetiology during hospitalisation. MH are a rare phenomenon with heterogeneous aetiology. Most frequently, the cause is hearing impairment; other causes include social isolation, cognitive dysfunction, vascular risk factors and medication. Studies suggest that some brain areas related to musical memory circuitry might be related and not fully mapped. Auditory verbal hallucinations with a voice that either comments, talks or sings to the patient have never been described in the literature, making this clinical case attractive.
- External approach to bilaterally septated maxillary sinuses: a case reportPublication . Gameiro, Pedro; Saldanha, Bernardo; Santos, Francisco; Silva, Jéssica; Norte, João; Reis, João; Sottomayor, Pedro; Vaz, Rodolfo; Rodrigues, PedroThe careful planning of a sinus lift procedure is the key to avoiding surgical complications. In this clinical case, a female patient, 59 years old and totally edentulous in the maxilla, was referred to Egas Moniz’s Dental Clinic Implantology consultation with indication for bilateral external sinus lift of the maxillary sinuses prior to implant placement. Both orthopantomography and cone-beam computed tomography were used to show the anatomy of the maxillary sinuses, which presented multiple sinus septa. A multiple anterolateral window approach was applied in order to avoid perforation of the Schneiderian membrane while accessing it.
- Impact of Artificial Intelligence Research on Politics of the European Union Member States: The Case Study of PortugalPublication . Reis, João; Santo, Paula; Melão, NunoCurrently, artificial intelligence (AI) is at the center of academic and public debate. However, its implications on politics remain little understood. To understand the impact of the AI phenomenon on politics of the European Union (EU), we have carried out qualitative multimethod research by performing a systematic literature review and a case study. The first method was performed according to the preferred reporting items for systematic reviews and meta-analyses (PRISMA), in order to report the state-of-the-art in the existing literature and explore the most relevant research areas. The second method contained contributions from experts in data science and AI of the Portuguese scientific community. The results showed that solutions such as intelligent decision support systems are improving the political decision-making process and impacting the Portuguese society at local, regional, and national levels. We also found that practitioners and scientists are currently shifting their interests from environmental and biological sciences to healthcare services, which is bringing new challenges in terms of protecting patient/citizen data and growing concerns about handling of critical information. Future research may focus on comparative studies with other EU States to obtain a comprehensive and holistic understanding of the AI phenomenon.
- O Impacto dos Conflitos Regionais nas Relações OTAN/UE-RússiaPublication . Reis, JoãoO estudo tem como objecto analisar os mais recentes conflitos regionais, pós implosão da União das Repúblicas Socialistas Soviéticas (URSS) sua caracterização (origens, objectivos, localização geográfica), a atitude da Organização do Tratado do Atlântico Norte (OTAN), União Europeia (EU) e Rússia perante os mesmos, e o impacto nas relações entre estes actores. Tendo em conta a diferente probabilidade de ocorrência de conflitos, optou-se por centrar a atenção sobre os países emergentes das ex-republicas soviéticas com o objectivo principal de identificar os factores que actualmente mais condicionam esse relacionamento, referenciar quais os conflitos regionais com maior impacto, e, formular uma prospectiva das relações entre a OTAN, UE e Rússia face à deflagração de novos conflitos regionais. Desta reflexão resultaram sugestões de contributos para as políticas de segurança da OTAN e energética da UE e, bem assim, de Portugal. Para atingir os objectivos delineados a investigação orientou-se na resposta a uma pergunta central (Quais as perspectivas de evolução das relações da OTAN,UE e Rússia face à possivel deflagração de conflitos regionaisnos Newly Independent States?), apoiada em questões derivadas e em hipóteses que foram sendo validadas ao longo do trabalho, procurando determinar-se quais os objectivos e condutas dos principais actores em situações concretas actuais. O estudo efectuado foi de base documental, excepto na análise dos conflitos do Afeganistão e do Kosovo em que o autor beneficiou, para a análise, do testemunho directo de Oficias Generais com experiencia naqueles Teatros de Operações. Os resultados obtidos da investigação permitem-nos afirmar que o alargamento da OTAN é considerado pela Rússia como uma ameaça à sua segurança e interesses nacionais; o petróleo e gás natural da região do Mar Cáspio e Ásia Central são fundamentais para o Ocidente; a Rússia tentará controlar os frozen conflicts no seu processo de reconstrução da sua esfera de influência; a ocorrência de conflitos continuará a condicionar as relações futuras entre a OTAN, UE e Rússia; e, a associação da força e poder militar com a política energética continuará a constituir um instrumento de poder. A investigação efectuada permite-nos concluir que a OTAN, UE e Rússia procurarão desenvolver uma política de acomodação como parceiros e rivais, evitando o confronto directo, instrumentalizando e limitando o número de conflitos regionais nas respectivas esferas de influência, mas colaborando pragmaticamente nas suas políticas de segurança e energéticas desde que os seus interesses vitais não sejam ameaçados. Se necessário recorrerão a políticas coercivas e mesmo ao uso directo da força nos Newly Independent States (NIS), pelo que a deflagração de novos conflitos regionais não pode ser descartada. Abstract: The aim of this paper is to analyze the newest regional conflicts, post implosion of the Union of Soviet Socialist Republics (USSR), their main characteristics (origins, objectives and geographic localization), the reaction of the North Atlantic Treaty Organization (NATO), European Union (EU) and Russia, and their impact on the relations among these key Actors. Taking into account the probalility of conflicts to arise, we have focused on the emergent states of the former Soviet republics aiming to identify the major factors that restraint the relationship among NATO, EU and Russia; to point out the regional conflicts with greater impact; and to prospect the evolution of this trilateral relationship if regional conflicts takes place. Finally, it is humbly suggested some recommendations for the security policy and energy policy of NATO, EU and Portugal. In order to fulfill the objectives of the paper the investigation was directed to answer a key estimate question (What are the prospects of the evolution the relations of NATO, EU and Russia if a regional conflict in a Newly Independent States occurs?) and secondary questions, to find out the chief objectives and conduct of the key Actors in real regional confrontations. The study was mainly based upon open documentation, except for the analisys of the conflicts of Afghanistan and Kosovo that received the contribution of two experienced Army Generals on those Theater of Operations. The key findings of this study is that the eastward enlargement of NATO is viewed by Russia as a threat to the russian security and national interests; the oil and natural gas from South Caucasus and Central Asia are fundamental for Western interests; Russia will try to manage the frozen conflict in the reconstruction process of her sphere of influence; regional conflicts will restraint the relations among NATO, EU and Russia; and, the combination of military force and energy policy will be an instrument of power. The investigation concludes that NATO, EU and Russia will seek a policy of accommodation as partners and rivals; will avoid any direct military confrontation, managing and restricting the number of regional conflicts in their spheres of influence, but will pragmatically co-operate in their security and energy policy if their vital interests are not threatened. If necessary, they will use coercive policies and the use of direct military force in the Newly Independent States.

- Military Training Mission in Iraq: An Exploratory Case Study ResearchPublication . Reis, João; Reis, Bruno; Nowakowska, Marta; Kazanecka, AnetaThe purpose of this paper is to investigate how military training is being conducted by NATO coalition forces in Iraq. Thus, the intent of this paper is to discuss the implications of existing misalignments between the military forces that are providing the training and those receiving it. To that end, we have used an exploratory case study research, which included multiple sources of data collection for corroboration and triangulation purposes. The results that emerged from the content analysis showed two types of outcomes that may be relevant to improve the military training in Iraq. The first outcome is identified as the intangible actions, which were mainly focused on social relations, with the intent of narrowing the cultural gap between the international coalition and Iraqi forces. Without surprising, a second outcome is identified as tangible actions, which were associated with training programs and the establishment of tactics, techniques, and procedures (TTPs) relevant to small and medium military units. Future research should focus on programs of “training the trainers” in order to develop long-term teaching and move forward with sustainable Iraqi Security Forces (ISF).
