Testo completoAt the forefront of maritime logistics, this dissertation explores the transformative potential of blockchain technology to enhance supply chain traceability and facilitate secure, multi-source data exchange.Through a deep analysis of blockchain applications, the research meticulously examines how this emerging technology can significantly elevate transparency, strengthen traceability, and fortify security within the global trade arena. By weaving together a comprehensive theoretical framework and real-world case studies, this scholarly endeavour sheds light on the multifaceted challenges and opportunities associated with integrating blockchain into maritime logistics. It critically evaluates the technology's impact on the traceability of critical data within maritime information systems, such as dangerous goods and identification logs, with the potential to extend to broader inter- and intra-data exchange. This dissertation not only contributes to academic knowledge but also serves as a compelling call to action for innovators and policymakers in the maritime and technology sectors. It advocates for an innovative approach that fosters deeper engagement with the possibilities of blockchain-driven transformation. This approach views blockchain not as a replacement, but as a complementary layer to existing maritime information systems. It envisions seamless integration and utilization of customized and evaluated blockchain technology within the maritime sector, ensuring its coherence with industry-specific requirements and ongoing digitization trends. This research aims to provide insights that enhance the understanding of blockchain technology's implications for the evolving global trade and logistics landscape
Zhang, Hongchang. "Ordonnancement cyclique robuste appliqué à la gestion des conteneurs dans les ports maritimes de taille moyenne". Thesis, Ecole centrale de Lille, 2014. http://www.theses.fr/2014ECLI0018/document.
Testo completoThis PhD thesis is dedicated to propose a robust cyclic scheduling methodology applied to container management of medium sized seaport which faces ever changing terminal conditions and the limited predictability of future events and their timing. The robust cyclic scheduling can be seen not just a predictable scheduling to compute a container transportation schedule, but also a reactive scheduling to eliminate the disturbances in real time. In this work, the automated intelligent vehicles (AIV) are used to transport the containers, and the P-time strongly connected event graph (PTSCEG) is used as a graphical tool to model the container transit procedures. Before the arrival of the container vessel, a cyclic container transit schedule can be given by the mixed integer programming (MIP) method in short time. The robustness margins on the nodes of the system can be computed by robustness algorithms in polynomial computing time. After the stevedoring begins, this robust cyclic schedule is used. When a disturbance is observed in system, it should be compared with the known robustness margin. If the disturbance belongs to the robustness margin, the robustness algorithm is used to eliminate the disturbance in a few cycle times. If not, the MIP method is used to compute a new cyclic schedule in short time

Testo completoThe Port of Marseille-Fos, strengthened by its 10 000 hectares located at the mouth of the second largest river of the mediterranean basin is a center piece of a global network and a central core of a local network. Interfacing maritime and land stakes, the area which is influenced by this international port must become aware of this complex system which surrounds it. It is the main object of this action research work. The approach presented is structured around the concept of the "territorial manufacturing plant" which links the analytical vision of productivity to that of the plant and the systemic vision associated to sustainable territorial development. This concept has enabled the setting up of a process based on volontary prospective, concertation, action and innovation, which aroused the port's local network, which allowed it to change from a passive state to a receptive one. . . First step toward a territorial pact. The work carried out is based on a precise analysis of the port system problematic and it proposes a method which allows to coordinate the territorial "manufacturing plant" in order to better understand and govern its regulation systems / retroactions (economic, environmental and social). The concrete results are presented and commented in order to finally propose a Territorial Economic Intelligence Master Plan for the areas influenced by the Port of Marseille-Fos. This thesis is the first step of a long process which will lead this territory toward new richnesses

Testo completoMusculoskeletal disorders (MSD) are the leading cause of occupational disease in France.MSDs affect all areas of industry and services; from heavy and manufacturing industry to personal assistance services and handling in logistics centers.MSDs may appear after carrying loads, this task being particularly critical because of the intense and repeated efforts that it requires. One solution to prevent the appearance of MSDs is to physically assist workers in order to reduce the effort involved.Exoskeletons appear to be one of the most promising tools for providing this assistance.However, their control is one of the locks slowing down their deployment in the industry.This doctoral project aims to investigate control and command of an exoskeleton in interaction with an operator. Thus, a strategy to control an upper-limb exoskeleton for load carrying assistance, without prior knowledge of the mass, was developed and integrated.The originality of this research work lies in two points. The first one is the estimation of the user's intention as a torque via his muscular activity, measured with electromyographic sensors. And the second one is the use of this estimated intention in the effort control of an exoskeleton. This approach makes possible to compensate the weight of loads that are not known beforehand.This intention detection system is based on a hybrid method integrating a model of the torque applied according to the muscular activity and an artificial neural network, in order to evaluate the direction of the movement intended.The control system was then evaluated through an experimental protocol with ten participants. It was found that this method induced : (i) performances equivalent to a classical gravity compensation assistance (with prior knowledge of the load), but also (ii) a reduction of the participant's muscular activity (biceps, anterior deltoid, and erector spinae).Finally, a method of personalization of the the control system based on the user's response time was designed.The impact of the personalization of the parameters (controller gain) on the users was also analyzed, and this work demonstrated that this personalization facilitates the intuitive handling of the system.During development, particular attention was given to proposing an approach that could be easily deployed in the workplace, in order to take into account the industrial orientation of the applications.Indeed, this research work opens up new application perspectives for active exoskeletons dedicated to load carrying, such as in professional logistic area

This work had the main goal of analyzing the process of implementation of the Business Intelligence tool (BI) in a small company of the retail area of the construction of the West of Paraná (Brazil). As secondary objectives were raised the main limiters that restrict the implementation of the tool, it was evaluated the contribution of the Business Intelligence tool to the performance of the organization, and propose an implementation model for small companies. Therefore, we used the case study method with direct observation and interviews with the managers and collaborators who use the tool. The results obtained in the study demonstrated that there are several limitations to the implementation of Business Intelligence in small companies, among them, hardware and software limitation, process limitations and limitation of human resources. Such limitations can easily be overcome through the use of a model, which contemplates a flow of activities to be followed, demonstrating that the benefits generated by the tool for the performance of these organizations are notorious. Thus, the study was justified by the contribution that Business Intelligence brings to the performance of small companies, besides contributing directly to regional development through the role of employment creation, income and taxes of these enterprises.
Este trabalho teve como objetivo analisar o processo de implantação da ferramenta Inteligência de Negócio (IN) em uma empresa de pequeno porte da área de varejo da construção do Oeste do Paraná (Brasil). Como objetivos secundários foram levantados os principais limitadores que restringem essa implementação, foi avaliada a contribuição da ferramenta Inteligência de Negócio para o desempenho da organização, além de ser proposto um modelo de implementação para empresas de pequeno porte. Para tanto foi utilizado o método de estudo de caso com observação direta e entrevistas com os gestores e colaboradores que utilizam a ferramenta. Os resultados obtidos no estudo demonstram que existem diversas limitações para a implantação da Inteligência de Negócio em pequenas empresas, dentre eles, limitação de hardware e software, limitações de processo e limitação de recursos humanos. Tais limitações podem ser superadas facilmente a partir da utilização de um modelo que contemple um fluxo de atividades a ser seguido, demonstrando que são notórios os benefícios gerados pela ferramenta para o desempenho destas organizações. Desta forma, o estudo justificou-se pela contribuição que a Inteligência de Negócio traz para o desempenho das pequenas empresas, além de contribuir diretamente com o desenvolvimento regional pelo papel de geração de emprego, renda e tributos destes empreendimentos.

Testo completoA growing number of physical objects are being connected to the Internet at an unprecedented rate realizing the idea of the Internet of Things (IoT). Wearables are a class of IoT devices worn on the body that can detect and process physiological signals. A wearable can then give bio-feedback to the wearer or send information to the cloud for further analysis. In this context, the Ellcie-Healthy start-up is developing an intelligent and connected eyewear solution with the aim at improving the user’s quality of life and to prevent risks for their health and safety. To do so, several sensors are integrated into the wearable eyeglass to collect and send physical, physiological and environmental information towards a gateway, typically a smartphone. Designing wearable devices deals with numerous challenges such as the energy consumption, the quality of service (QoS) and the scalability, to cite only a few. Several design constraints, such as the autonomy and QoS, must be addressed early in the design flow to ensure the wearable device will meet the user requirements. In this PhD thesis, we propose a simulation flow based on a system-level modeling approach to help designers making the best choices of hardware/software settings early in the design phase. To do so, we have first developed analytical power models for the Ellcie Healthy smart glasses. These models, built from data measured on the real platform, allow estimating the average power consumption of the system, and so the battery lifetime, for different application scenarios. Then, performance constraints have also been considered in our system-level approach. The drowsiness detection application, developed at Ellcie Healthy, has been profiled to identify the hardware and software configurations impacting the most the energy consumption and the application QoS, i.e. the detection performance. A solution based on a Convolutional Neural Network (CNN) has been proposed to further improve the drowsiness detection QoS. We have also demonstrated that it is possible to execute this CNN at the edge (i.e. on a micro-controller). A battery testbench has also been developed to evaluate battery safety conditions as well as the aging phenomenon. Using this experimental platform, a significant amount of information on the battery charge/discharge process has been collected. A data-driven battery model has been proposed and validated. All these models have been integrated into a simulation framework which allows modeling and simulating existing or future versions of the smart connected glasses. Using this framework, designers can rapidly investigate trade-offs between hardware and/or software settings, as well as study system autonomy and application QoS. In addition, this simulation flow can be used to evaluate power management strategies from a high-level point of view

Testo completoWe are drowning in massive data but starved for knowledge retrieval. It is well known through the dimensionality tradeoff that more data increase informative but pay a price in computational complexity, which has to be made up in some way. When the labeled sample size is too little to bring sufficient information about the target concept, supervised learning fail with this serious challenge. Unsupervised learning can be an alternative in this problem. However, as these algorithms ignore label information, important hints from labeled data are left out and this will generally downgrades the performance of unsupervised learning algorithms. Using both labeled and unlabeled data is expected to better procedure in semi-supervised learning, which is more adapted for large domain applications when labels are hardly and costly to obtain. In addition, when data are large, feature selection and instance selection are two important dual operations for removing irrelevant information. Both of tasks with semisupervised learning are different challenges for machine learning and data mining communities for data dimensionality reduction and knowledge retrieval. In this thesis, we focus on co-selection of instances and features in the context of semi-supervised learning. In this context, co-selection becomes a more challenging problem as the data contains labeled and unlabeled examples sampled from the same population. To do such semi-supervised coselection, we propose two unified frameworks, which efficiently integrate labeled and unlabeled parts into the co-selection process. The first framework is based on weighting constrained clustering and the second one is based on similarity preserving selection. Both approaches evaluate the usefulness of features and instances in order to select the most relevant ones, simultaneously. Finally, we present a variety of empirical studies over high-dimensional data sets, which are well-known in the literature. The results are promising and prove the efficiency and effectiveness of the proposed approaches. In addition, the developed methods are validated on a real world application, over data provided by the State Railway of Thailand (SRT). The purpose is to propose the application models from our methodological contributions to diagnose the performance of rail dry port systems. First, we present the results of some ensemble methods applied on a first data set, which is fully labeled. Second, we show how can our co-selection approaches improve the performance of learning algorithms over partially labeled data provided by SRT

Testo completoThe work presented in this thesis contributes to the field of the extended enterprise and the development of distributed information systems. This is obviously an important subject of study for the logistics community (supply chain), but also for the software engineering community. It is in this context that the objectives are to provide a model of global supply chain in an intermodal environment door to door service to solve the problems: (i) interfaces between the different actors involved along the chain and (ii) trans-loading operations generated by the goods transfer operations from one mode of transport to another. Thus, improved performance of the supply chain depends heavily on the level of cooperation and coordination, and especially sharing and validity of information and knowledge between the different actors in the chain (transport organizer, forwarding, Supplier, etc.). The application is located in the corridor of the Seine valley. The work is part of the project APLOG (Performance Improvement and global logistics) financed by the Haute Normandie region

SIMTUR - Sistema Inteligente De Monitoramento de Tráfego Urbano
O crescente aumento do uso de automóveis e de motocicletas tem provocado uma contínua degradação no trânsito urbano das grandes metrópoles. Este cenário é agravado pelas deficiências nos atuais sistemas de transporte público, geradas, em parte, pela falta de informação ao usuário. O presente trabalho apresenta um modelo computacional para um sistema de informação ao usuário de transporte público. Ao contrário de outros trabalhos baseados no algoritmo clássico Dijkstra, a abordagem apresentada faz uso do algoritmo A* para resolução do problema de caminhos mínimos, presente neste contexto, a fim de reduzir o tempo de resposta de maneira que o modelo possa ser utilizado em um sistema real de informação ao usuário. O modelo proposto considera múltiplos critérios de decisão, como a distância total percorrida e o número de transbordos. Um estudo de caso foi realizado utilizando dados reais do transporte público da cidade Porto Alegre com o objetivo de avaliar o modelo computacional desenvolvido. Os resultados gerados foram comparados com aqueles obtidos através do emprego do algoritmo Dijkstra e indicam que a combinação do algoritmo A* com técnicas de aceleração permite reduzir, significativamente, a complexidade de espaço, o tempo de processamento e o número de transbordos.
The increasing use of automobiles and motorcycles has caused a continuous degradation in the traffic of large cities. This scenario gets worse due to shortcomings in the current public transportation, which is entailed, in a certain way, by the lack of information provided to the user. This study shows a computing model for a public transportation user information system. Unlike other studies based on the classical Dijkstra’s algorithm, the approach makes use of the algorithm A* to solve a shortest path problem to reduce the response time so that the model can be used in an real-time web information system. The proposed model takes into account multiple criteria of decision, such as total distance traveled and number of transfers and it was evaluated with data from Porto Alegre’s public transportation. The results were compared to those ones obtained by the use of Dijkstra’s algorithm and indicate that the combination of algorithm A* with acceleration techniques allows reducing significantly the space complexity, processing time and the number of transfers.

Testo completoA logistic system is an essential component of a spatial system. Actors are organised around infrastructures in order to move different kinds of flow (of goods, of information, or financial) over a territory. The logistic organisation comes from an auto-organised and distributed process from the actors. This works aims to understand, at different scales, how autonomous and heterogeneous actors (according to their goals and methods to take decisions) are collectively organised around infrastructures to manage different kinds of flow, and despite numerous constraints (temporal, spatial,...). We propose an agent-based model which allows to simulate the processes to create and organise logistic flow over a territory. The model describes an interface between international and urban flow in order to understand how the port and urban dynamics work together. The model integrates a structural and organisational dynamics thanks to dynamic graphs in order to represent the evolution of this kind of system. Thus, the agents can adapt themselves to system's perturbations as in the reality

Competitive Intelligence (CI) is an emergent topic with strategic importance for nations and enterprises, and with your continuum theoretical development, arise the necessity to establish links with another knowledge fields. It has been identified a gap of empirical studies that seek to relate CI with Top Management Involvement, an essential factor for the development of this activity within the organization. More than initial support of resources and legitimacy, Top Management Involvement presupposes the commitment and continuous participation of the Top Management in programs of this nature, a behavior that can be of significant influence for its success or failure. So, this research aimed to analyze the relationship between Top Management Involvement and the Context and Process dimensions of Competitive Intelligence Model in medium and large companies of Serra Gaúcha Brazil. Also, it has been proposed to learn about the level of CI development level in the region, limited to organizations of this size, and to explore the relations between Top Management Involvement, Competitive Intelligence and Performance at this organizations. Thus, a descriptive and quantitative research was carried out, based on a survey sample of 160 organizations, measured by scales proposed by another international studies and based on the theoretical model of context and process of IC. Results indicated that there is positive relationship between Top Management Involvement and the IC Development Level at the medium and large companies at Serra Gaúcha, and three out of four scenarios proposed can be perceived. Also there is a positive association between IC, Organizational Performance, Top Management Involvement and IC integration with the decision making process of these organizations. In general, it was observed that most of these companies developed some kind of monitoring (information collecting), even though they do not nominate this activity as "Intelligence". The main focus of monitoring are Sales, Competitors and Innovation in Products, which indicates a beginning of this field development in the companies of this region.d

Testo completoThe current tendency is to use the multi-antennas systems in emission and/or reception in order to optimize the radioelectric spectrum as well as possible and to improve the radio connexion for the wireless communication systems. It is in this context that this thesis is related to the study and optimization of a demonstrator of smart antennas. After having carried out a thorough study of the detection methods of directions of arrival of the RF signals and having developed a beamforming technique, two prototypes of adaptive antenna system were developed in the WiMax band (3. 4 - 3. 5 GHz) and experimentally validated. The first system functioning in reception is based on the Uplink. It uses the five-port demodulators and the numerical beamforming system where the weights are calculated by the SQP algorithm (technique of pattern synthesis developed) and directly applied to the signals in baseband in order to improve quality of the received signals i. E. To improve the signal to interference plus noice ratio. The second system functioning in emission is based on the Downlink ; it is an analogical beamforming system using the vectors modulators controlled numerically, starting form the weight given by the array pattern synthesis (SQP algorithm) in order to concentrate the radiation emitted in the desired direction of the useful receiver. These two systems are complementary insofar as the last one uses the results of measurement of DoA of the first one to adapt its radiation pattern according to the position angular of the sources

Tecon Rio Grande
São crescentes os estudos voltados para o desenvolvimento de estratégias de integração e orientação à cadeia de suprimentos. Porém, a especificidade de cada cadeia exige que estudos sejam delineados conforme as características de cada indústria. Este trabalho pretende apresentar um modelo que auxilie na gestão de relacionamentos estratégicos de um terminal de containers, com base em conceitos relacionados a orientação à cadeia de suprimentos. O modelo é originado a partir da extensão do modelo de integração proposto por Lambert et al. (1998) e do modelo de mensuração da integração dos terminais portuários, desenvolvido por Song e Panayides (2007) e Panayides e Song (2008). Nesta proposta, são delimitados 3 diferentes níveis de relacionamento estratégico: monitoramento, mediação e criação de soluções, desenvolvidos a partir da inteligência de mercado que baliza os relacionamentos chave dimensionados pela estratégia do terminal portuário. O presente estudo propõe a aplicação do modelo desenvolvido no Tecon Rio Grande, terminal de containers do Porto de Rio Grande, a partir de duas etapas de pesquisa. A primeira etapa é uma pesquisa quantitativa e serviu para dimensionar a aderência entre a estratégia de orientação à cadeia da organização com relação aos seus relacionamentos chave, identificando possíveis discrepâncias. Nesta primeira etapa é apresentado o mapa de orientação ao relacionamento estratégico, ferramenta fundamental para análise. A segunda etapa trata-se de uma pesquisa qualitativa realizada para identificar os motivos das distorções apontadas pelos usuários chave da cadeia. Os resultados empíricos encontrados nas duas etapas da pesquisa demonstram que o modelo estendido apresentado alcança seu objetivo de identificar a OCS percebida e as variações aos diferentes níveis de relacionamento estrtégico, resultando como ferramenta para gestão de relacionamentos chave de terminais portuários.
There are increasing studies focused on the development of integration strategies and guidance to the supply chain. However, the specificity of each chain requires studies delineated according to the characteristics of each industry. This work intends to present a model that assists in managing strategic relationships of a container terminal, based on concepts related to supply chain orientation. The model is derived from the extent of the integration model proposed by Lambert et al. (1998) and the measurement model of the integration of port terminals, developed by Song and Panayides (2007) and Panayides and Song (2008). At this model are defined three different levels of strategic relationships: monitoring, mediation and creating solutions developed from market intelligence and targeted to key relationships scaled by the strategy of the port terminal. This study proposes to apply the model developed in Tecon Rio Grande, container terminal at the Port of Rio Grande, from two stages of research. The first step is a quantitative research and served to scale the adhesion between the chain orientation strategies of the organization with respect to their key relationships, identifying possible discrepancies. In this first step is also presented the map of the strategic relationship orientation, a fundamental tool for analysis. The second stage it is a qualitative research conducted to identify the reasons for the distortions noted by the chain members. Empirical results demonstrate that the extended model presented can be used as a tool for management of key relationships.
Espinoza, Castellon Fabiola. "Contributions to effective and secure federated learning with client data heterogeneity". Electronic Thesis or Diss., université Paris-Saclay, 2024. http://www.theses.fr/2024UPASG007.
Testo completoThis thesis addresses two significant challenges in federated learning: data heterogeneity and security. In the first part of our work, we tackle the data heterogeneity challenge. Clients can have different data distributions due to their personal opinions, locations, habits, etc. It is a common and almost inherent obstacle in real-world federated learning applications. We focus on two distinct types of heterogeneity in classification tasks. On the one hand, in the first scenario, participants exhibit diverse yet related data distributions, making collaborative learning an attractive approach. Our first proposed method leverages a domain adaptation approach and collaboratively learns an empirical dictionary. A dictionary expresses each client's data as a linear combination of various atoms, that are a set of empirical samples representing the training data. Clients learn the atoms collaboratively, whereas they learn the weights privately to enhance privacy. Subsequently, the dictionary is utilized to infer classes for the clients' unlabeled distribution that withal actively participated in the learning process. On the other hand, our second method addresses a different form of data heterogeneity, where clients express different concepts through their distributions. Collaborative learning may not be optimal in this context; however, we assume a structural similarity between clients, enabling us to cluster them into groups for more effective group-based learning. In this case, we direct our attention to the scalability of our method by supposing that the number of participants can be very large. We propose to incrementally, each time the server aggregates the clients' updates, estimate the hidden structure between clients. Contrary to alternative approaches, we do not require that all be available at the same time to estimate their belonging clusters. In the second part of this thesis, we delve into the security challenges of federated learning, specifically focusing on defenses against training time backdoor attacks. Since a federated framework is shared, it is not always possible to ensure that all clients are honest and that they all send correctly trained updates.Federated learning is vulnerable to the presence of malicious users who corrupt their training data. Our defenses are elaborated for trigger-based backdoor attacks, and rooted in trigger reconstruction. We do not provide the server additional data or client information, other than the compromised weights. After some limited assumptions are made, the server extracts information about the attack trigger from the compromised model global model. Our third method uses a reconstructed trigger to identify the neurons of a neural network that encode the attack. We propose to prune the network on the server side to hinder the effects of the attack. Our final method shifts the defense mechanism to the end-users, providing them with the reconstructed trigger to counteract attacks during the inference phase. Notably, both defense methods consider data heterogeneity, with the latter proving to be more efficient in extreme data heterogeneity cases. In conclusion, this thesis introduces novel methods to enhance the efficiency and security of federated learning systems. We have explored diverse data heterogeneity scenarios, proposing collaborative learning approaches and robust security defenses based on trigger reconstruction. As part of our future work, we outline perspectives for further research, improving our proposed trigger reconstruction and taking into account other challenges, such as privacy which is very important in the field of federated learning

Recently, an e-learning platform has been applied for scholars in the teaching, and it can effectively assist and obviously enhance students’ learning performance for most of students. Therefore, the role of teachers in the classroom has been gradually transformed into the counseling on the sidelines, and makes students learn self-directed learning and self-management, developing the ability of judgment and independent thinking and beyond conventional learning thinking. However, students’ knowledge background can only be judged by humane, not by the assistant of the system. Therefore, it will be an important issue for teachers to carry out meaningful teaching lessons based on each student’s knowledge background. It could increase the burden on teachers if we rely much on teachers to assess the improvement of students in knowledge background. In this thesis, an intelligent essay assessment system was proposed to analysis the content on the online discussion posts. At first, the keywords were extracted via the association rules, and then combined the sets selected by the experts or teachers. Next, we integrated the concepts of term frequency and TF-IDF, and did the classification with one-class SVM. Finally, we can determine if the students’ posts were correct or not, and this system can thus ease the burden on teachers. The experimental results indicated that the proposed essay assessment system can improve the recall rate, the accuracy rate, and the precision rate in terms of the performance of document classification before and after the combination of the keywords, and therefore, the burden on teachers can be alleviated with the proposed system.

This research examines the impact of underdog brand on consumers’ brand preference, as well as the moderating roles of emotional intelligence and sponsored posts in the impact of underdog brand on consumers’ brand preference. The research model is based upon the constructs and inferred hypotheses, and a 2 (with underdog brand story vs. without underdog brand story) × 2 (with sponsored posts vs, without sponsored posts) between-subjects factorial experimental design is conducted. Results demonstrate that underdog brand story has a positive impact on consumers’ brand preference. Moreover, the extent of emotional intelligence has no impact on consumers’ brand preference. Similarly, the availability of sponsored posts has no impact on consumers’ brand preference. Additionally, underdog brand story has a positive impact on consumers’ brand preference, regardless of the extent of consumers’ emotional intelligence. Similarly, underdog brand story has a positive impact on consumers’ brand preference, regardless of the availability of sponsored posts. Subsequently, consumers’ emotional intelligence has no impact on brand preference, regardless of the availability of sponsored posts. At last, underdog brand story has a positive impact on consumers’ brand preference, regardless of the availability of sponsored posts and the extent of consumers’ emotional intelligence.

An interactivity analysis of Facebook posts - a case study of the fan page of the Intelligent Ironman Creativity Contest Abstract Facebook is a social networking service launched on February 5, 2004. It also started the new era of media and promotion. However, how to write a post is close related to the effectiveness on interaction with readers. This in term affects the influence of the post. This thesis used data from Intelligent Ironman Creativity Contest, analyzed post time (2 hrs duration in a day), post days (Monday to Sunday), number of words (every 200 words up to 1200), post type (photo, link, Status, video and share video) and post content (evaluative, Informative, entertainment, profitable). The result could be useful guidelines in managing fan page for high school and creativity related activities This research collects 1119 posts from October 1st, 2014 to October 31st, 2018 as samples. We use 110 posts which is the top 10% posts with highest number of like, post, share as the base for quantitative and qualitative analysis. Finally, we examine the content of the top 3% posts and find the common pattern for attract readers. The results show that there is significant effect on post time, post day and post type. But posts with words from 600 to 800 are the most effective than other number of words. When the post types are video and link, short explanation is not enough. If there are action requests, reader costumed phrases or shared memories in the post, the post is very effective in interaction with readers. Key Words:interactivity analysis of Facebook posts, Educational activities, Intelligent Ironman Creativity Contest

Testo completoA Porto Editora, uma das mais antigas e maiores editoras educacionais em Portugal, teve um percurso de 77 anos de sucesso na vanguarda da inovação com retornos sólidos e uma posição de liderança no mercado. No entanto, nos últimos tempos, tem-se mostrado relutante em iniciar uma mudança disruptiva. As tecnologias digitais estão facilmente a revolucionar o mundo em que vivemos, bem como a forma como as pessoas aprendem e ensinam. À medida que a educação se orienta gradualmente para soluções digitais, grandes atores internacionais como a Pearson Education, McGraw Hill, etc., adaptaram os seus modelos de negócio às novas regras do jogo, capitalizando numa das maiores tendências tecnológicas e pedagógicas - Inteligência Artificial e Personalização da Educação. Mas a Porto Editora tem tido tendência para se afastar. Este caso demonstra a notável transformação de uma editora educativa tradicional numa empresa moderna e orientada para o futuro, o que dá à empresa uma fonte sustentável de vantagem competitiva. Ilustra também o chamado Dilema do Inovador, que descreve os principais desafios com que os incumbentes se deparam para provocar mudanças disruptivas.

Testo completoA visualização da informação, nomeadamente através dos dashboards, é comumente usada de forma a auxiliar o público-alvo, neste caso, Agrupamentos de Centros de Saúde (ACES ) e investigadores do setor da saúde, no seu processo de tomada de decisão. Tendo isto como base, este estudo tem como objetivo a elaboração de um dashboard com uma interface amiga do utilizador, que colmate as lacunas presentes nos dashboards disponibilizados pelo SNS, assim como verificar se a Acessibilidade Espacial tem um impacto estatisticamente relevante no número de consultas nos Cuidados de Saúde Primários, numa primeira fase recorrendo ao teste de correlação de Perason’s, seguido pela aplicação dos testes ANOVA e Kruskall-Wallis e, por último, procedendo à análise dos Principais componentes. Dois métodos matemáticos foram usados de forma a calcular a Acessibilidade Espacial, nomeadamente, o método Two-Step-Floating catchment area e o rácio supply-to-demand. Através deste estudo foi possível perceber que a Acessibilidade Espacial difere entre freguesias do mesmo concelho, sendo que à medida que as freguesias se afastam do centro do concelho a Acessibilidade Espacial decresce. Esta, quando calculada através do rácio supply-to-demand, em que a unidade são os centros de saúde, tem um efeito estatisticamente relevante no número de consultas. Na Análise dos Componentes Principais, alguns fatores sugerem que certos tipos de consulta são mais utilizados por determinadas faixas etárias, assim como certas faixas etárias são mais influenciadas pela Acessibilidade Espacial do que outras.

Testo completoThis study, has had as goal accomplish a descriptive analysis of the Multiple Intelligences of a sample of students from the second and third cycles relating them to personal and academic variables. The sample consisted of 512 students (48.8% of the male gender and 51.2% of the female gender) of four private schools in the Oporto Metropolitan Area. These students attended the 5th grade (47,3%) and the 7th grade (52,7%) and were aged between 9 and 15 years. The data collection was done through the scale Multiple Intelligences Survey for Kids (MISK; Candler, 2011), which was adapted for the Portuguese population by Mendes (2015). The results indicate that girls present higher values in relation to boys at the level of Intelligence Linguistic, Musical, Spatial-Visual, Corporal-Kinaesthetic and Interpersonal. The boys stand out more in Logical-Mathematical Intelligence. Regarding the year of schooling, the results show that the students of 5th Year present higher values than the students of 7th Year in the Naturalistic, Verbal-Linguistic, Musical, Spatial-Visual and Corporal-Kinaesthetic Intelligence. Finally, the results indicate the existence of a statistically significant positive correlation between Intelligences Logical-Mathematical and Interpersonal Intelligence and academic achievement in Mathematics and Logical-Mathematical, Verbal-Linguistic, Kinaesthetic and Interpersonal Intelligence and Portuguese academic performance.

Testo completoIn the twenty-first century, governance is a central element in citizens' lives and in the growth of cities as a place where a diversified range of services (commercial, industrial, cultural, religious, infrastructure and consumer services) is concentrated. The most diverse flows and human activities. We focus research on the "element" city, with its varied interpretations over time, with expected conditions to extend the concept of governance and sovereignty to regions and / or metropolitan areas. As for the sovereignty of the territory, the approach is more abstract, because it refers to an entity, which knows no higher entity in the external order nor equal in the internal order. However, the sovereignty of the territory has to be rebalanced at this level, since the digital one changes the relations of power and the limitation of the physical space confined to the borders. This proposal aims to validate models of governance in smart cities in the applicability of public policies that lead to a reinforcement of the sovereignty of the territory that will pass through the creation of new frontiers that will enable the States to reorganize them into a network and at the same time guarantee their survival, as well as their sovereignty. An opportunity to understand the evolution of Porto - case study - over the last few years in the perspective of planning, demographic management and governance, at the political decision level since the big European bet in Smart cities is and will be, a "window of opportunity" for regeneration of the city, its renovation and even rehabilitation, since it will be a capacitive bet to self-sustain, increasing the economic opportunities for those who live and for those who pass through the city, minimizing the costs of communications, as well as environmental damage, and ease of access to information.
Au XXI siècle, la gouvernance est un élément central de la vie des citoyens et de la croissance des villes en tant que lieu de concentration d'une gamme diversifiée de services (commerciaux, industriels, culturels, religieux, d'infrastructure et de consommation). Les flux les plus divers et les activités humaines. Nous focalisons la recherche sur la ville «élément», avec ses interprétations variées dans le temps, avec les conditions attendues pour étendre le concept de gouvernance et de souveraineté aux régions et / ou zones métropolitaines.Quant à la souveraineté du territoire, l'approche est plus abstraite, car elle fait référence à une entité qui ne connaît aucune entité supérieure dans l'ordre extérieur ni égale dans l'ordre interne. Cependant, la souveraineté du territoire doit être rééquilibrée à ce niveau, puisque le numérique change les rapports de pouvoir et la limitation de l'espace physique confiné aux frontières.Cette proposition vise à valider les modèles de gouvernance pour les villes intelligentes dans l'application des politiques publiques qui conduisent à un renforcement de la souveraineté du territoire qui nécessitera la mise en place de nouvelles frontières qui permettent aux États de la réorganisation du réseau et en garantissant en même temps son la survie, ainsi que leur souveraineté.Une opportunité de comprendre l'évolution de Porto - étude de cas - au cours des dernières années dans la perspective de la planification, de la gestion démographique et de la gouvernance, au niveau décisionnel politique puisque le grand pari européen dans les Smart cities est et sera, une «fenêtre d'opportunité» pour la régénération de la ville, son renouvellement et à la réhabilitation, tout comme étant un pari capacitif autonome, l'amélioration des possibilités économiques pour ceux qui vivent et ceux qui traversent la ville, tout en minimisant les coûts de les communications, ainsi que les dommages environnementaux et la facilité d'accès à l'information.

Testo completoA Inteligência emocional é a interação entre o estado cognitivo e as emoções de modo a capacitar o sujeito a se adaptar de forma adequada perante o meio. A partir do modelo de ramificação de Mayer que divide as competências e habilidades de Inteligência Emocional em quatro domínios: a) percepção e expressão de emoções, b) assimilação de emoções, c) compreensão e análise das emoções e d) gestão de emoções, tem-se a construção das cinco competências básicas da inteligência emocional: a) autoconsciência, b) gestão das emoções, c) automotivação, d) empatia e e) gestão de emoções em grupos que compõem a Inteligência emocional. Estas competências foram avaliadas por este trabalho visando investigar o desenvolvimento da inteligência emocional entre os professores da educação básica na rede publica e na rede privada de ensino da cidade de Porto Seguro, na Bahia, Brasil. A amostra, composta 120 professores da educação básica distribuídos na rede pública e na rede privada de ensino, respondeu à Escala Veiga Branco para competência emocional em professores. A escala é composta por 15 itens e foi desenhada com o objetivo de conhecer as atitudes que identificam as cinco competências emocionais dos professores, a partir do constructo teórico da inteligência emocional de Golemam (1995) distribuído em 85 fatores totais da escala. Os resultados apontam para um nível mediano de inteligência emocional entre os professores, não existindo diferenças significativas entre professores da rede pública ou da rede privada, bem como para a não existência de diferenças significativas entre professores que atuam na educação infantil, no ensino fundamental e ensino médio. Tais resultados apontam para um desenvolvimento mais elevado em alguns fatores que compõe cada competência, evidenciando uma clara necessidade de um trabalho de intervenção visando uma formação para o maior desenvolvimento da inteligência emocional na profissão docente.
Emotional Intelligence is an interaction between the cognitive function and the emotions adapting the person at the environment: Mayer’s model divide EI in four possibilities a) perception and expression of emotions, b) assimilation of emotions, c) understanding and analysis of emotions, D) managing emotions, for the other side in theses theory has five competences a) selfawareness, b) emotions management, c) self motivation, d) empathy and e) manage emotions in groups. The goal of this research was evaluation the EI with teachers from Porto Seguro – Ba. These teachers work in public and private elementary school in this city. For this study, applied 120 questionaries with teachers from elementary school in Porto Seguro. The questionnaires propose the Veiga Branco Scale for investigate the emotional competences in teachers. The scale is composed by 15 factors and was created with the goal to identify the five emotional competences of the teachers, using the Goleman’s (1995) theory for understand the emotional intelligence. Goleman’s theory propose understand 85 factors in the scale. It results shows that no have differences between teachers from private schools or public schools. They shows no have to important differences between the teachers from child education, elementary and middle schools. These results show for us that have a higher development in some factors that compose each competence, but the demonstrate to a important need for the researcher propose a formation for theses teachers. This formation can help the teachers to develop the Emotional intelligence in yours networks.
