Palaces, as an architectural typology, can be found in recreation Quintas that surrounded the main cities in Portugal, which preserved its rural character since the 16th century until the middle of the 19th century. Consisting of cultivated land and farm buildings, the palace of the Quinta was the owner´s temporary residence, for summer holidays and festive events, with gardens, pavilions, fountains and lakes for recreational purposes and leisure. The focus on palaces, as a historic building and as in need of new uses, clearly shows how current the debate on contemporary interventions in this heritage typology is. Interventions in architectural heritage require multidisciplinary teams to identify conservation strategies which enable a qualified use of its spaces, such as for example the experience of security and well-being, which can contribute to a better quality of life and simultaneously to the quality of the urban environment. This paper presents the Palace of Quinta Alegre and its rehabilitation project for contemporary use and public esteem, both of which are considered fundamental prerequisites for its sustainable maintenance in space, in time and in memory. [versão Portuguesa] Sob a denominação de tipologia arquitectónica, o edifício Palácio pode ser encontrado nas Quintas de Recreio que rodeavam as principais cidades Portuguesas, tendo preservado o seu carácter rural, desde o século XVI até metade do século XIX. Consistindo as Quintas em terra cultivada e edifícios rurais, o Palácio da Quinta consistia na residência temporária do proprietário, para férias de verão e eventos comemorativos, dispondo de jardins, pavilhões, fontes e lagos para recreação e lazer. O tema dos Palácios, entendido como edifício histórico que procura novos usos, demonstra como é actual o debate sobre intervenções contemporâneas nesta tipologia de valor patrimonial. A intervenção em património arquitectónico requer a definição de estratégias de conservação por equipas multidisciplinares que permitam estabelecer um uso qualificado dos seus espaços, proporcionando experiências sensoriais de bem-estar e segurança, contribuindo para uma melhor qualidade de vida e, simultaneamente, para a qualidade do ambiente urbano em que se insere. Este artigo tem por objectivo apresentar o Palácio da Quinta Alegre e o projecto de reabilitação, devolvendo-o a um uso contemporâneo e à estima pública, factores fundamentais para a sua manutenção sustentável no espaço, no tempo e na memória.

The root knot nematode (RKN), Meloidogyne incognita, is widespread worldwide and a major pathogen of several cultivated crops. The use of resistant genotypes is the most effective and environmentally sound way to manage RKN. In this study, we screened 16 selected sweet potato cultivars including Amanda, Bárbara, Beatriz, Beauregard, Brazlândia Branca, Brazlândia Rosada, Brazlândia Roxa, BRS Amélia, BRS Cuia, BRS Rubissol, Carolina Vitória, Duda, Júlia, Marcela, PA-26/2009, and Princesa obtained from Embrapa and Universidade Federal do Tocantins? germplasm bank. Studies were conducted under greenhouse and field conditions and the agronomic performance of the cultivars was evaluated in a nematode and soilborne insect-infested field. All 16 sweet potato cultivars tested were rated as resistant to this nematode both under greenhouse and field conditions with reproduction factors < 1. In the field infested with M. incognita, sweet potato cultivars Duda, BRS Amélia, Beauregard, Brazlândia Rosada, and Brazlândia Roxa stood out as superior cultivars, with average yield ranging from 26 to 47 tons per ha. Overall, most cultivars exhibited a fusiform to near fusiform root shape, a good characteristic for the market, and were moderately affected by insects (attack incidence 1 to 30%). As global demand for energy continues to rise, selecting new cultivars of sweet potatoes with increased resistance to nematode diseases and with high yield will be important for food security and biofuel production.

L’elaborato ha ad oggetto lo studio della tematica inerente alla prevenzione e alla risoluzione dei conflitti di giurisdizione tra autorità giudiziarie appartenenti a Paesi membri dell’Unione europea, in presenza di un reato caratterizzato da elementi di transnazionalità. In questi casi è necessario elaborare alcuni canoni idonei a individuare per tempo l’autorità giudiziaria competente a condurre l’attività di accertamento. Tale esigenza sorge a causa della lacunosità ed insufficienza dell’attuale normativa (Decisione quadro 2009/948/GAI) sotto molteplici profili: il riferimento è tanto alla carenza di tassatività e cogenza dei criteri necessari a radicare la giurisdizione in un determinato Stato, quanto all’irrilevanza, nelle dinamiche inerenti alla scelta del foro, dei diritti di difesa dell’indagato. In questa prospettiva, occorre dunque trovare un punto di equilibrio tra le istanze repressive e quelle di tutela dei diritti fondamentali: detto altrimenti, l’esigenza di evitare di prevenire “zone franche” nello Spazio di libertà, sicurezza e giustizia – anche alla luce della libertà di movimento dei soggetti e dunque dei criminali – non può comportare la lesione della sfera giuridica del cittadino europeo. Il presente lavoro di ricerca, sulla scorta dell'analisi tanto dei principi quanto delle regole attualmente vigenti, si pone l'obiettivo di individuare delle guidelines in linea con il portato garantistico della Carta dei diritti fondamentali dell'Unione europea ed efficaci per assolvere il mandato presente all’art. 82, § 1, lett. b) TFUE: ossia di prevenire e risolvere i conflitti di giurisdizione.

The objective of this thesis is the small area estimation of an economic security indicator. Economic security is a complex concept that carries a variety of meanings. In the literature there is no a formal unambiguous definition for economic security and in this work we refer to the definition recently provided for its opposite, economic insecurity, as the “anxiety produced by the possible exposure to adverse economic events and by the anticipation of the difficulty to recover from them” (Bossert and D’Ambrosio, 2013). In the last decade interest for economic insecurity/security has grown constantly, especially since the financial crisis of 2008, but even more in the last year after the economic consequences due to the Covid-19 pandemic. In this research, economic security is measures through a longitudinal indicator that takes into account the income levels of Italian households, from 2014 to 2016. The target areas are groups of Italian provinces, for which the indicator is estimated using longitudinal data taken from EU-SILC survey. We notice that the sample size is too low to obtain reliable estimates for our target areas. Therefore we resort to some Small Area Estimation strategies to improve the reliability of the results. In particular we consider small area models specified at area level. Besides the basic Fay-Herriot area-level model, we propose to consider some longitudinal extensions, including time-specific random effects following an autoregressive processes of order 1 (AR1) and a moving average of order 1 (MA1). We found that all the small area models used show a significant efficiency gain, especially MA1 model.

To change unadapted water governing systems, and water users’ traditional conducts in line with climate change, understanding of systems’ structures and users’ behaviors is necessary. To this aim, comprehensive and pragmatic research was designed and implemented in the Urmia Lake Basin where due to the severe droughts, and human-made influences, especially through the agricultural development, the lake has been shrunken drastically. To analyze the water governance and conservation issues in the basin, an innovative framework was developed based on mathematical physics concepts and pro-environmental behavior theories. Accordingly, in system level (macro/meso), the problem of fit of the early-shaped water governing system associating with the function of “political-security” and “political-economic” factors in the basin was identified through mean-field models. Furthermore, the effect of a “political-environmental” factor, the Urmia Lake Restoration Program (ULRP), on reforming the system structure and hence its fit was assessed. The analysis results revealed that by revising the provincial boundaries (horizontal alternation) for the entity of Kurdistan province to permit that interact with the headquarter of West Azerbaijan province for its water demand-supply initiatives, the system fit can increase. Also, the constitution of the ULRP (vertical arrangement) not only could increase the structural fit of the water governing system to the basin, but also significantly could enhance the system fit through its water-saving policy. Besides, in individual level (micro), the governing factors of water conservation behavior of the major users/farmers were identified through rational and moral socio-psychological models. In rational approach, incorporating PMT and TPB, the SEM results demonstrated that “Perceived Vulnerability”, “Self-Efficacy”, “Response Efficacy”, “Response Cost”, “Subjective Norms” and “Institutional Trust” significantly affect the water-saving intention/behavior. Likewise, NAM based analysis as a moral approach, uncovered the significant effects of “Awareness of Consequences”, “Appraisal of Responsibility”, “Personal Norms” as well as “Place Attachment” and “Emotions” on water-saving intention.

Today more than ever, with the recent war in Ukraine and the increasing number of attacks that affect systems of nations and companies every day, the world realizes that cybersecurity can no longer be considered just as a “cost”. It must become a pillar for our infrastructures that involve the security of our nations and the safety of people. Critical infrastructure, like energy, financial services, and healthcare, have become targets of many cyberattacks from several criminal groups, with an increasing number of resources and competencies, putting at risk the security and safety of companies and entire nations. This thesis aims to investigate the state-of-the-art regarding the best practice for securing Industrial control systems. We study the differences between two security frameworks. The first is Industrial Demilitarized Zone (I-DMZ), a perimeter-based security solution. The second one is the Zero Trust Architecture (ZTA) which removes the concept of perimeter to offer an entirely new approach to cybersecurity based on the slogan ‘Never Trust, always verify’. Starting from this premise, the Zero Trust model embeds strict Authentication, Authorization, and monitoring controls for any access to any resource. We have defined two architectures according to the State-of-the-art and the cybersecurity experts’ guidelines to compare I-DMZ, and Zero Trust approaches to ICS security. The goal is to demonstrate how a Zero Trust approach dramatically reduces the possibility of an attacker penetrating the network or moving laterally to compromise the entire infrastructure. A third architecture has been defined based on Cloud and fog/edge computing technology. It shows how Cloud solutions can improve the security and reliability of infrastructure and production processes that can benefit from a range of new functionalities, that the Cloud could offer as-a-Service.We have implemented and tested our Zero Trust solution and its ability to block intrusion or attempted attacks.

Industry 4.0 refers to the 4th industrial revolution and at its bases, we can see the digitalization and the automation of the assembly line. The whole production process has improved and evolved thanks to the advances made in networking, and AI studies, which include of course machine learning, cloud computing, IoT, and other technologies that are finally being implemented into the industrial scenario. All these technologies have in common a need for faster, more secure, robust, and reliable communication. One of the many solutions for these demands is the use of mobile communication technologies in the industrial environment, but which technology is better suited for these demands? Of course, the answer isn’t as simple as it seems. The 4th industrial revolution has a never seen incomparable potential with respect to the previous ones, every factory, enterprise, or company have different network demands, and even in each of these infrastructures, the demands may diversify by sector, or by application. For example, in the health care industry, there may be e a need for increased bandwidth for the analysis of high-definition videos or, faster speeds in order to have analytics occur in real-time, and again another application might be higher security and reliability to protect patients’ data. As seen above, choosing the right technology for the right environment and application, considers many things, and the ones just stated are but a speck of dust with respect to the overall picture. In this thesis, we will investigate a comparison between the use of two of the available technologies in use for the industrial environment: Wi-Fi 6 and 5G Private Networks in the specific case of a steel factory.

Background. This paper examines the contributions of dispositional and non-dispositional factors to post-disaster psychological morbidity. Data reported are from the 845 participants in the longitudinal component of the Quake Impact Study. Methods. The phase 1 survey was used to construct dimensional indices of threat and disruption exposure. Subsequently, a range of dispositional characteristics were measured, including neuroticism, personal hopefulness and defence style. The main morbidity measures were the General Health Questionnaire (GHQ-12) and Impact of Event Scale (IES). Results. Dispositional characteristics were the best predictors of psychological morbidity throughout the 2 years post-disaster, contributing substantially more to the variance in morbidity (12-39%) than did initial exposure (5-12%), but the extent of their contribution was greater for general (GHQ-12) than for post-traumatic (IES) morbidity. Among the non-dispositional factors, avoidance coping contributed equally to general and post-traumatic morbidity (pr = 0.24). Life events since the earthquake (pr = 0.18), poor social relationships (pr = -0.25) and ongoing earthquake-related disruptions (pr = 0.22) also contributed to general morbidity, while only the latter contributed significantly to post-traumatic morbidity (pr = 0.15). Conclusions. Medium-term post-earthquake morbidity appears to be a function of multiple factors whose contributions vary depending on the type of morbidity experienced and include trait vulnerability, the nature and degree of initial exposure, avoidance coping and the nature and severity of subsequent events.

This paper develops a general framework for valuing a wide range of derivative securities. Rather than focusing on the stochastic process of the underlying security and developing an instantaneously-riskless hedge portfolio, we focus on the terminal distribution of the underlying security. This enables the derivative security to be valued as the weighted sum of a number of component pieces. The component pieces are simply the different payoffs that the security generates in different states of the world, and they are weighted by the probability of the particular state of the world occurring. A full set of derivations is provided. To illustrate its use, the valuation framework is applied to plain-vanilla call and put options, as well as a range of derivatives including caps, floors, collars, supershares, and digital options.

Venomous animals have evolved a vast array of peptide toxins for prey capture and defence. These peptides are directed against a wide variety of pharmacological targets, making them an invaluable source of ligands for studying the properties of these targets in different experimental paradigms. A number of these peptides have been used in vivo for proof-of-concept studies, with several having undergone preclinical or clinical development for the treatment of pain, diabetes, multiple sclerosis and cardiovascular diseases. Here we survey the pharmacology of venom peptides and assess their therapeutic prospects.

Este estudo tem como objetivo compreender a forma com que os mecanismos de governança corporativa interferem na gestão de uma pequena empresa familiar. Para isso, adotaram-se a perspectiva de Hart (1995), que discorre sobre governança corporativa, e de Leone (2005) para empresas familiares. Para alcançar este objetivo, adotou-se, em relação à condução da pesquisa, uma abordagem qualitativa, por meio do método do estudo de caso. A triangulação de dados foi utilizada como instrumento de coleta de dados por meio de pesquisa documental, observação assistemática e entrevista semiestruturada, e a análise de dados foi realizada através da análise de conteúdo. Como contribuição teórica, este estudo amplia o Modelo de Quatro Círculos com Contexto e Sistema de Valores com a introdução de proprietários formais e informais, gerando o Modelo de Cinco Círculos. A presença da governança corporativa foi identificada através dos fatores de diferenciação e da implantação de onze mecanismos de governança que gerou mudanças no controle da empresa, no processo sucessório, na profissionalização e na captação de recursos. Os mecanismos encontrados foram denominados como: “empresa controladora”; “respeito fraternal”; “projetos pessoais”; “pró-labore dos gestores familiares”; “ausência de remuneração dos familiares não gestores”; “aconselhamento profissional”; “prestação de contas”; “proteção do empreendimento familiar”; “alinhamento de interesses na gestão”; “atribuições e responsabilidades”; e “atenção aos interesses dos stakeholders”. Tais mecanismos não possuem ordem cronológica, pois o respeito fraternal e projetos pessoas já existiam antes da criação da empresa familiar. Quanto ao controle, destaca-se o mecanismo prestação de contas, que possibilitou uma ligação entre a família e a empresa; permitiu clareza, transparência, igualdade entre todos os irmãos, diminuindo a assimetria informacional; facilitou uma comunicação aberta e honesta entre todos os proprietários, transmitindo uma sensação de segurança e previsibilidade; e contribuiu para eliminar e/ou minimizar conflitos entre os proprietários (formais e informais). Quanto à sucessão, os mecanismos proteção do empreendimento familiar, aconselhamento profissional, respeito fraternal estão possibilitando planejar o processo sucessório da empresa; facilitaram a comunicação entre os familiares, e assim, diminuiu a assimetria informacional; e realizaram a manutenção e administração dos bens mobiliários da família empresária. Quanto à profissionalização, os mecanismos proteção do empreendimento familiar e respeito fraternal viabilizaram a participação de todos para decidir sobre a profissionalização da empresa. Com relação à captação de recursos, os mecanismos atribuições e responsabilidades e atenção aos interesses dos stakeholders possibilitaram a empresa, durante todo seu ciclo de vida, a buscar recursos financeiros sem dificuldade, gerando um maior investimento, crescimento e geração de empregos

O objeto de estudo dessa pesquisa é a política de segurança pública brasileira visando compreender o seu percurso ideológico e político no contexto de retomada e da consolidação da democracia no Brasil, após 21 anos de ditadura militar. Considerando o contexto no qual se verifica a existência de disputa política em torno da concepção de segurança pública, o objetivo geral deste trabalho é compreender a matriz estruturante da política de segurança pública no Brasil contemporâneo. Seu intuito visa responder à pergunta inicial e condutora do interesse que estrutura este trabalho, aqui apresentada nos seguintes termos: a política de segurança pública no Brasil após o restabelecimento das eleições diretas para a Presidência da República está em vias de transição, tendendo a assumir caráter democrático ou a força da tradição autoritária na cultura política brasileira tem-se garantido a sua continuidade neste campo da intervenção estatal? Ancoramos a nossa reflexão nas categorias teóricas de dominação, coerção e consenso no pensamento clássico de Hobbes, Marx, Weber e Gramsci, extraindo deles os elementos que nos auxiliam no entendimento da política de segurança pública brasileira. Para o estudo dessa política foi fundamental operarmos uma profunda revisão bibliográfica, especialmente para entender como a manutenção da ordem foi se desenhando no contexto brasileiro e como historicamente tem prevalecido um modelo de segurança pública marcado pelo autoritarismo. Entretanto, a partir da redemocratização brasileira há a emergência de outro paradigma para a política de segurança pública, a segurança cidadã, propondo, entre outras coisas, a reforma das instituições de segurança pública e a formação em direitos humanos nas instituições policiais. Para a análise do paradigma emergente de segurança, buscamos apoio no Programa Nacional dos Direitos Humanos e no Plano Nacional de Segurança Pública, documentos federais que representam a construção de uma nova intencionalidade para a segurança pública no Brasil. Finalmente, reconhecemos que, embora haja significativas reformas na segurança pública, tal política, diante da prevalência de um paradigma de segurança tradicional com fortes componentes autoritários, se encontra entre a segurança cidadã e a continuidade autoritária.
