According to Tilly, two laws shaped the process of transformation undergone by Western European societies since the Peace of Westphalia until the end of the 20th century: their increasing inner homogenisation and their growing heterogeneity between them. Cultural inner homogenisation affected, fi rst, those ethnic groups living within the territories of the said states. The second phase of homogenisation impinged on those groups that immigrated after World War II. This process followed different models according to the country considered, but the 1973 oil crisis revealed their general lack of success. During the last quarter of the 20th century and onwards, these European societies have been altered by two progressive and contradictory global logics: a process of cultural homogenisation at the world level (rather than society level) and a process of cultural re-creation led by those groups with an immigrant background, who have reacted against their integration shortcomings by searching for new sources of social and personal esteem in their respective cultural and religious traditions. This paper seeks to clarify these processes from a social differentiation and political representation theory perspective. The latter becomes indispensable, as the said processes have happened in a context in which the structure of relations (i.e. communication) between civil society and the democratic political sphere have experienced a radical crisis. In this way, the complex relations that exist between civil society, culture, religion and politics in these Western European societies are depicted.

Purpose: To qualitatively explore the communication between healthcare professionals and oncology patients based on the perception of patients undergoing chemotherapy.Method: Qualitative and exploratory design. Participants were 14 adult patients undergoing chemotherapy at different stages of the disease. A socio-demographic and clinical data form was utilized along with semi-structured interviews. The interviews were audio-recorded, transcribed and content analysis was performed. Two independent judges evaluated the interview content in regards to emerging categories and obtained a Kappa index of 0.834.Results: Three categories emerged from the data: 1) Technical communication without emotional support, in which the information provided is composed of strictly technical information regarding the diagnosis, treatment and/or prognosis; 2) Technical communication, in which the information provided is oriented towards the technical aspects of the patient’s physical condition, while also providing psychological support for the patients’ subjective needs; and 3) Insufficient technical communication, win which there are gaps in the information provided causing confusion and suffering to the patient.Conclusions: Communication with emotional support contributes to greater satisfaction of chemotherapy patients. Practical implications: the results provide elements for the training of healthcare professionals regarding the importance of the emotional support that can be offered to cancer patients during their treatment.

Les logiciels actuels sont de grandes tailles, complexes et critiques. Le besoin de qualité exige beaucoup de tests, ce qui consomme de grandes quantités de ressources durant le développement et la maintenance de ces systèmes. Différentes techniques permettent de réduire les coûts liés aux activités de test. Notre travail s’inscrit dans ce cadre, est a pour objectif d’orienter l’effort de test vers les composants logiciels les plus à risque à l’aide de certains attributs du code source. À travers plusieurs démarches empiriques menées sur de grands logiciels open source, développés avec la technologie orientée objet, nous avons identifié et étudié les métriques qui caractérisent l’effort de test unitaire sous certains angles. Nous avons aussi étudié les liens entre cet effort de test et les métriques des classes logicielles en incluant les indicateurs de qualité. Les indicateurs de qualité sont une métrique synthétique, que nous avons introduite dans nos travaux antérieurs, qui capture le flux de contrôle ainsi que différentes caractéristiques du logiciel. Nous avons exploré plusieurs techniques permettant d’orienter l’effort de test vers des composants à risque à partir de ces attributs de code source, en utilisant des algorithmes d’apprentissage automatique. En regroupant les métriques logicielles en familles, nous avons proposé une approche basée sur l’analyse du risque des classes logicielles. Les résultats que nous avons obtenus montrent les liens entre l’effort de test unitaire et les attributs de code source incluant les indicateurs de qualité, et suggèrent la possibilité d’orienter l’effort de test à l’aide des métriques.

BACKGROUND: Several analysis software packages for myocardial blood flow (MBF) quantification from cardiac PET studies exist, but they have not been compared using concordance analysis, which can characterize precision and bias separately. Reproducible measurements are needed for quantification to fully develop its clinical potential. METHODS: Fifty-one patients underwent dynamic Rb-82 PET at rest and during adenosine stress. Data were processed with PMOD and FlowQuant (Lortie model). MBF and myocardial flow reserve (MFR) polar maps were quantified and analyzed using a 17-segment model. Comparisons used Pearson's correlation ρ (measuring precision), Bland and Altman limit-of-agreement and Lin's concordance correlation ρc = ρ·C b (C b measuring systematic bias). RESULTS: Lin's concordance and Pearson's correlation values were very similar, suggesting no systematic bias between software packages with an excellent precision ρ for MBF (ρ = 0.97, ρc = 0.96, C b = 0.99) and good precision for MFR (ρ = 0.83, ρc = 0.76, C b = 0.92). On a per-segment basis, no mean bias was observed on Bland-Altman plots, although PMOD provided slightly higher values than FlowQuant at higher MBF and MFR values (P < .0001). CONCLUSIONS: Concordance between software packages was excellent for MBF and MFR, despite higher values by PMOD at higher MBF values. Both software packages can be used interchangeably for quantification in daily practice of Rb-82 cardiac PET.

A actividade vitivinícola possui um conjunto diverso de características presentes no solo, território e comunidade que fazem parte do património cultural de uma determinada região. Quando a tradição se traduz num conceito como terroir que é formado por características territoriais, sociais e culturais de uma região rural, o vinho apresenta uma “assinatura” que se escreve “naturalmente” no paladar regionalmente identificado. Os vinhos da Região de Nemea, na Grécia e de Basto (Região dos Vinhos Verdes) em Portugal, estão ambos sob a proteção dos regulamentos das Denominações de Origem. No entanto, apesar de ambos serem regulados por sistemas institucionais de certificação e controlo de qualidade, afigura-se a necessidade de questionar se o património cultural e a identidade territorial específica, “impressa” em ambos os terroirs, pode ser protegida num sentido mais abrangente do que apenas origem e qualidade. Em Nemea, a discussão entre os produtores diz respeito ao estabelecimento de sub-zonas, isto é incluir na regulação PDO uma diferente categorização territorial com base no terroir. Ou seja, para além de estar presente no rótulo a designação PDO, as garrafas incluirão ainda informação certificada sobre a área específica (dentro do mesmo terroir) onde o vinho foi produzido. A acontecer resultaria em diferentes status de qualidade de acordo com as diferentes aldeias de Nemea onde as vinhas estão localizadas. O que teria possíveis impactos no valor das propriedades e no uso dos solos. Para além disso, a não participação da Cooperativa de Nemea na SON (a associação local de produtores de vinho) e como tal na discussão principal sobre as mudanças e os desafios sobre o terroir de Nemea constitui um problema no sector vitivinícola de Nemea. Em primeiro lugar estabelece uma relação de não-comunicação entre os dois mais importantes agentes desse sector – as companhias vinícolas e a Cooperativa. Em segundo lugar porque constituiu uma possibilidade real, não só para os viticultores ficarem arredados dessa discussão, como também (porque não representados pela cooperativa) ficar impossibilitado um consenso sobre as mudanças discutidas. Isto poderá criar um ‘clima’ de desconfiança levando a discussão para ‘arenas’ deslocalizadas e como tal para decisões ‘desterritorializadas’ Em Basto, há vários produtores que começaram a vender a sua produção para distribuidoras localizadas externamente à sub-região de Basto, mas dentro da Região dos Vinhos Verdes, uma vez que essas companhias tem um melhor estatuto nacional e internacional e uma melhor rede de exportações. Isto está ainda relacionado com uma competição por uma melhor rede de contactos e status mais forte, tornando as discussões sobre estratégias comuns para o desenvolvimento rural e regional de Basto mais difícil de acontecer (sobre isto a palavra impossível foi constantemente usada durante as entrevistas com os produtores de vinho). A relação predominante entre produtores é caracterizada por relações individualistas. Contudo foi observado que essas posições são ainda caracterizadas por uma desconfiança no interior da rede interprofissional local: conflitos para conseguir os mesmos potenciais clientes; comprar uvas a viticultores com melhor rácio qualidade/preço; estratégias individuais para conseguir um melhor status político na relação com a Comissão dos Vinhos Verdes. Para além disso a inexistência de uma activa intermediação institucional (autoridades municipais e a Comissão de Vinho Verde), a inexistência entre os produtores de Basto de uma associação ou mesmo a inexistência de uma cooperativa local tem levado a região de Basto a uma posição de subpromoção nas estratégias de promoção do Vinho Verde em comparação com outras sub-regiões. É também evidente pelos resultados que as mudanças no sector vitivinícolas na região de Basto têm sido estimuladas de fora da região (em resposta também às necessidades dos mercados internacionais) e raramente de dentro – mais uma vez, ‘arenas’ não localizadas e como tal decisões desterritorializadas. Nesse sentido, toda essa discussão e planeamento estratégico, terão um papel vital na preservação da identidade localizada do terroir perante os riscos de descaracterização e desterritorialização. Em suma, para ambos os casos, um dos maiores desafios parece ser como preservar o terroir vitivinícola e como tal o seu carácter e identidade local, quando a rede interprofissional em ambas as regiões se caracteriza, tanto por relações não-consensuais em Nemea como pelo modus operandi de isolamento sem comunicação em Basto. Como tal há uma necessidade de envolvimento entre os diversos agentes e as autoridades locais no sentido de uma rede localizada de governança. Assim sendo, em ambas as regiões, a existência dessa rede é essencial para prevenir os efeitos negativos na identidade do produto e na sua produção. Uma estratégia de planeamento integrado para o sector será vital para preservar essa identidade, prevenindo a sua desterritorialização através de uma restruturação do conhecimento tradicional em simultâneo com a democratização do acesso ao conhecimento das técnicas modernas de produção vitivinícola.

The PROSPER (Proof and Specification Assisted Design Environments) project advocates the use of toolkits which allow existing verification tools to be adapted to a more flexible format so that they may be treated as components. A system incorporating such tools becomes another component that can be embedded in an application. This paper describes the PROSPER Toolkit which enables this. The nature of communication between components is specified in a language-independent way. It is implemented in several common programming languages to allow a wide variety of tools to have access to the toolkit.

Changes in the circumstances of the Australian pineapple industry left growers with a leadership vacuum, limited technical support and no funds for conducting research and marketing. Inspirational leadership training together with regular district farm meetings were used to assist the Australian pineapple industry to successfully adapt to these challenges. All growers were assigned to one of a number of regional grower study groups and regular on-farm meetings commenced to facilitate communication between growers, transfer of technology, awareness of industry affairs and an opportunity to become involved in industry business. A leader was appointed within each study group and these leaders attended a leadership course consisting of three, three-day modules. These original course graduates formed the nucleus of a new grower representative group which subsequently instigated levies to fund research and marketing. Two more courses have since been conducted to provide the depth of leadership to satisfy the growers' desire to rotate industry leadership on a regular basis.

Non-adherence to health recommendations (e.g. medical prescriptions) presents potential costs for healthcare, which could be prevented or mitigated. This is often attributed to a person’s rational choice, to not adhere. However, this may also be determined by individual and contextual factors implied in the recommendations communication process. In accordance, this chapter focuses specifically on barriers to and facilitators of adherence to recommendations and engagement with the healthcare process, particularly concerning the communication between health professionals and patients. For this, the authors present examples of engagement increment through different degrees of participation, from a one-way/directive towards a two-way/engaging communication process. This focuses specifically on a vulnerable population group with increasing healthcare needs: older adults. Future possibilities for two-way engaging communications are discussed, aimed at promoting increased adherence to health recommendations and people’s self-regulation of their own health.

The past few decades have witnessed the widespread adaptation of wireless devices such as cellular phones and Wifi-connected laptops, and demand for wireless communication is expected to continue to increase. Though radio frequency (RF) communication has traditionally dominated in this application space, recent decades have seen an increasing interest in the use of optical wireless (OW) communication to supplement RF communications. In contrast to RF communication technology, OW systems offer the use of largely unregulated electromagnetic spectrum and large bandwidths for communication. They also offer the potential to be highly secure against jamming and eavesdropping. Interest in OW has become especially keen in light of the maturation of light-emitting diode (LED) technology. This maturation, and the consequent emerging ubiquity of LED technology in lighting systems, has motivated the exploration of LEDs for wireless communication purposes in a wide variety of applications. Recent interest in this field has largely focused on the potential for indoor local area networks (LANs) to be realized with increasingly common LED-based lighting systems. We envision the use of LED-based OW to serve as a supplement to RF technology in communication between mobile platforms, which may include automobiles, robots, or unmanned aerial vehicles (UAVs). OW technology may be especially useful in what are known as RF-denied environments, in which RF communication may be prohibited or undesirable. The use of OW in these settings presents major challenges. In contrast to many RF systems, OWsystems that operate at ranges beyond a few meters typically require relatively precise alignment. For example, some laser-based optical wireless communication systems require alignment precision to within small fractions of a degree. This level of alignment precision can be difficult to maintain between mobile platforms. Additionally, the use of OW systems in outdoor settings presents the challenge of interference from ambient light, which can be much brighter than any LED transmitter. This thesis addresses these challenges to the use of LED-based communication between mobile platforms. We propose and analyze a dual-link LED-based system that uses one link with a wide transmission beam and relaxed alignment constraints to support a more narrow, precisely aligned, higher-data-rate link. The use of an optical link with relaxed alignment constraints to support the alignment of a more precisely aligned link motivates our exploration of a panoramic imaging receiver for estimating the range and bearing of neighboring nodes. The precision of such a system is analyzed and an experimental system is realized. Finally, we present an experimental prototype of a self-aligning LED-based link.

O presente estudo tem o objetivo de investigar a adequação das transmissões (meios, estrutura das redes e interoperabilidade) atualmente empregues nas Baterias de Bocas de Fogo (Btrbf), face aos novos requisitos operacionais, presentemente materializados na necessidade de emprego de Unidades de Escalão Pelotão (UEP), e dando resposta aos requisitos impostos pela implementação do Sistema Automático de Comando e Controlo (SACC) da Artilharia de Campanha (AC) Portuguesa, procurando desta forma identificar que alterações deverão ocorrer. Para alcançar o desiderato proposto, recorremos a entrevistas exploratórias, com uma amostra de cinco oficiais, de forma aprofundar e expandir o conhecimento sobre a temática em questão, usando posteriormente uma abordagem dedutiva, baseada nos resultados das entrevistas e em doutrina nacional e estrangeira, de forma a chegar a possíveis conclusões. Esta investigação centrou-se em três grandes temáticas: os novos requisitos no emprego da AC; o SACC e a problemática das comunicações; e o emprego de Pelotões de Bocas de Fogo (Pelbf), sendo que estas estão interligadas entre si na dimensão das redes e meios de comunicações. Estas temáticas foram abordadas com um raciocínio de forma descendente: partindo dos novos requisitos impostos à atuação da AC, passando pelas limitações do SACC e culminado com a identificação das redes e meios necessários para o emprego de Pelbf. Como principais conclusões deste estudo, apontamos a necessidade de resolução das incompatibilidades entre os componentes do sistema automático e o rádio tático PRC-525, podendo a solução passar pela atualização do próprio SACC, para um sistema compatível com o rádio português. Identificámos ainda a necessidade de introduzir uma nova rede, exclusiva da Btrbf, e adaptar algumas das existentes em função do nível de implementação do SACC. Estas redes implicam, diretamente, um reforço do número de meios rádio em certos órgãos da Btrbf.

To analyze the characteristics and predict the dynamic behaviors of complex systems over time, comprehensive research to enable the development of systems that can intelligently adapt to the evolving conditions and infer new knowledge with algorithms that are not predesigned is crucially needed. This dissertation research studies the integration of the techniques and methodologies resulted from the fields of pattern recognition, intelligent agents, artificial immune systems, and distributed computing platforms, to create technologies that can more accurately describe and control the dynamics of real-world complex systems. The need for such technologies is emerging in manufacturing, transportation, hazard mitigation, weather and climate prediction, homeland security, and emergency response. Motivated by the ability of mobile agents to dynamically incorporate additional computational and control algorithms into executing applications, mobile agent technology is employed in this research for the adaptive sensing and monitoring in a wireless sensor network. Mobile agents are software components that can travel from one computing platform to another in a network and carry programs and data states that are needed for performing the assigned tasks. To support the generation, migration, communication, and management of mobile monitoring agents, an embeddable mobile agent system (Mobile-C) is integrated with sensor nodes. Mobile monitoring agents visit distributed sensor nodes, read real-time sensor data, and perform anomaly detection using the equipped pattern recognition algorithms. The optimal control of agents is achieved by mimicking the adaptive immune response and the application of multi-objective optimization algorithms. The mobile agent approach provides potential to reduce the communication load and energy consumption in monitoring networks. The major research work of this dissertation project includes: (1) studying effective feature extraction methods for time series measurement data; (2) investigating the impact of the feature extraction methods and dissimilarity measures on the performance of pattern recognition; (3) researching the effects of environmental factors on the performance of pattern recognition; (4) integrating an embeddable mobile agent system with wireless sensor nodes; (5) optimizing agent generation and distribution using artificial immune system concept and multi-objective algorithms; (6) applying mobile agent technology and pattern recognition algorithms for adaptive structural health monitoring and driving cycle pattern recognition; (7) developing a web-based monitoring network to enable the visualization and analysis of real-time sensor data remotely. Techniques and algorithms developed in this dissertation project will contribute to research advances in networked distributed systems operating under changing environments.

In Europe almost 80% of the continent's population lives in cities. It is estimated that by 2030 most regions in Europe which contain major cities will have even more inhabitants on 35–60% more than now. This process generates a consequent elevate human pressure on the natural environment, especially around large urban agglomerations. Cities could be seen as an ecosystem, represented by the dominance of humans that re-distribute organisms and fluxes and represent the result of co-evolving human and natural systems, emerging from the interactions between humans, natural and infrastructures. Roads have a relevant role in building links between urban components, creating the basis on which it is founded the urban ecosystem itself. This thesis is focused on the research for a comprehensive model, framed in European urban health & wellbeing programme, aimed to evaluate the determinants of health in urban populations. Through bicycles, GPS and sensor kits, specially developed and produced by University of Bologna for this purpose, it has been possible to conduct on Bologna different direct observations that oriented the novelty of the research: the categorization of university students cyclists, connection among environmental data awareness and level of cycling, and an early identification of urban attributes able to impact on road air quality and level of cycling. The categorization of university students’ cyclist has been defined through GPS analysis and focused survey, that both permit to identify behavioural and technical variables and attitudes towards urban cycling. The statistic relationship between level of cycling, seen as number of bicycles passages per lane and pollutants level, has been investigated through an inverse regression model, defined and tested through SPSS software on the basis of the data harvest. The research project that represents a sort of dynamic mobility laboratory on two wheels, that permits to harvest and study detected parameters.

The integration of distributed and ubiquitous intelligence has emerged over the last years as the mainspring of transformative advancements in mobile radio networks. As we approach the era of “mobile for intelligence”, next-generation wireless networks are poised to undergo significant and profound changes. Notably, the overarching challenge that lies ahead is the development and implementation of integrated communication and learning mechanisms that will enable the realization of autonomous mobile radio networks. The ultimate pursuit of eliminating human-in-the-loop constitutes an ambitious challenge, necessitating a meticulous delineation of the fundamental characteristics that artificial intelligence (AI) should possess to effectively achieve this objective. This challenge represents a paradigm shift in the design, deployment, and operation of wireless networks, where conventional, static configurations give way to dynamic, adaptive, and AI-native systems capable of self-optimization, self-sustainment, and learning. This thesis aims to provide a comprehensive exploration of the fundamental principles and practical approaches required to create autonomous mobile radio networks that seamlessly integrate communication and learning components. The first chapter of this thesis introduces the notion of Predictive Quality of Service (PQoS) and adaptive optimization and expands upon the challenge to achieve adaptable, reliable, and robust network performance in dynamic and ever-changing environments. The subsequent chapter delves into the revolutionary role of generative AI in shaping next-generation autonomous networks. This chapter emphasizes achieving trustworthy uncertainty-aware generation processes with the use of approximate Bayesian methods and aims to show how generative AI can improve generalization while reducing data communication costs. Finally, the thesis embarks on the topic of distributed learning over wireless networks. Distributed learning and its declinations, including multi-agent reinforcement learning systems and federated learning, have the potential to meet the scalability demands of modern data-driven applications, enabling efficient and collaborative model training across dynamic scenarios while ensuring data privacy and reducing communication overhead.

The purpose of this thesis is to present the concept of simulation for automatic machines and how it might be used to test and debug software implemented for an automatic machine. The simulation is used to detect errors and allow corrections of the code before the machine has been built. Simulation permits testing different solutions and improving the software to get an optimized one. Additionally, simulation can be used to keep track of a machine after the installation in order to improve the production process during the machine’s life cycle. The central argument of this project is discussing the advantage of using virtual commissioning to test the implemented software in a virtual environment. Such an environment is getting benefit in avoiding potential damages as well as reduction of time to have the machine ready to work. Also, the use of virtual commissioning allows testing different solutions without high losses of time and money. Subsequently, an optimized solution could be found after testing different proposed solutions. The software implemented is based on the Object-Oriented Programming paradigm which implies different features such as encapsulation, modularity, and reusability of the code. Therefore, this way of programming helps to get simplified code that is easier to be understood and debugged as well as its high efficiency. Finally, different communication protocols are implemented in order to allow communication between the real plant and the simulation model. By the outcome that this communication provides, we might be able to gather all the necessary data for the simulation and the analysis, in real-time, of the production process in a way to improve it during the machine life cycle.
