Metody analýzy a simulací sociálních sítí / Social Network Analysis and Simulations

Vorlová, Pavla January 2013 (has links)
This diploma thesis is focusing on description of processing social network analysis, design and implementation of a model that simulates a particular social network and its analysis. Social networks are modern and very used in this time. They are very good point for exploring. This project deal with static analysis social network, where social network is constructed by graph. We nd out di erent properties of single component and than we establish signi cance of them. Relationships between components are important too for us, because they have a big influence on propagation information in network. Structural properties figure out existence of di fferent communities. We simulate social network with multi-agent systems, they are desirable for represent changes in network. Multi-agent systems have implemented a simulation model that represents a particular social network. His behaviour was analyzed and examinated by chosen methods.

Centralidades, redes e escalas : uma análise de Marília a partir das Instituições de Ensino Superior, das indústrias de alimentos e dos serviços de saúde /

Oliveira, Pablo Muryllo de January 2019 (has links)
Orientador: Márcio José Catelan / Resumo: No mundo contemporâneo as mudanças no âmbito socioespacial decorrem de articulações complexas. Avistando este contexto, este trabalho que tem como orientação teórico-metodológica as interações espaciais interescalares advindos dos efeitos do processo de Globalização, um dos processos que mais afeta e orienta o modo como a produção das cidades e da rede tem se dado. Estas mudanças atuam na redefinição dos papéis e funções urbanas das cidades articuladas em redes, daí analisarmos as redes e as centralidades que se formam em Marília no âmbito desta perspectiva. Nosso foco se dá a partir de três setores: os serviços de saúde, as indústrias de alimentos de consumo final e as Instituições de Ensino Superior. Esses setores estruturam as redes hierárquicas e heterárquicas de Marília, complexificando o modo que a cidade se insere no sistema urbano e sua atuação escalar se amplia em qualidade e quantidade. Para isto no dedicamos a dados secundários que reunimos a fim de compreender como estes três setores foram sendo articulados por meio de relações interescalares redefinindo a Marília como uma cidade média. / Mestre

Orientador: Arthur Magon Whitacker / Resumo: Com esta tese de doutorado identificamos e compreendemos a ocorrência, distribuição e tipologia de centros no interior da conurbação Cuiabá-Várzea Grande; além de verificar a ocorrência de disposições hierárquicas neste espaço, com vistas a identificação da multicentralidade. Para isso, utilizamo-nos dos conceitos de centro e centralidade a partir de aspectos teóricos que contribuíram com o desenvolvimento de estratégias metodológicas de investigação. Após delimitados os conceitos, aplicamos metodologias de organização e representação cartográfica de dados secundários, visando a identificação de espaços marcados pela concentração de determinadas atividades do setor terciário da economia e por padrões espaciais de direcionamento e intensidade de circulação de pessoas usuárias do transporte coletivo. A partir da associação analítica desses dados, elaboramos um quadro da ocorrência e distribuição dos centros de maior destaque no contexto da conurbação. Os resultados revelaram um espaço urbano constituído por múltiplos centros, estando a maior parte desses localizados em áreas incorporadas ao perímetro urbano só após a década de 1960, quando se verificou o despontar de um acentuado processo de urbanização, manifesto por uma considerável expansão territorial urbana e crescimento demográfico, impulsionado por um contexto regional marcado pelo advento de um novo clico econômico e produtivo: o do agronegócio.

Vers une centralité de la Région ? Émergence et affirmation du rôle de la Région Île-de-France en matière climat-air-énergie / Towards a central role of regional authority? Emergence and affirmation of the Île-de-France regional council in climate, air and energy policies

Gerardin, Noé 25 May 2018 (has links)
La « montée en puissance des Régions » semble aujourd’hui une évidence dans nombre de travaux universitaires, en France comme à l’étranger. Dans quelle mesure l’apparition de nouveaux enjeux comme l’environnement participe-t-elle à ce mouvement ? Cette montée en puissance s’observe-t-elle dans le domaine des politiques climatiques, énergétiques et de qualité de l’air en France ? Si tel est le cas, comment se traduit-elle ? Pour répondre à ces questions, la présente thèse étudie les évolutions du rôle de la Région Île-de-France en matière de politiques énergétiques, climatiques et de qualité de l’air des années 1990 à aujourd’hui. Il est mis en lumière un mouvement de montée en puissance de cette Région sur les questions climat-air-énergie, processus qui se traduit par une place de plus en plus centrale de cette collectivité dans le système d’acteurs intervenant en la matière. Le constat de ce « gain de centralité » de la Région Île-de-France a été permis par une combinaison d’approches relevant du droit et de la science politique. Croiser les apports de ces disciplines a contribué à appréhender à la fois les acteurs en présence, leurs relations, leurs compétences, les contraintes et ressources dont ils disposent, et les usages faits de ces dernières. Sont explorés dans cette thèse les compétences de la Région Île-de-France, ses moyens financiers et humains, son positionnement vis-à-vis des autres acteurs franciliens et son usage des normes juridiques. Deux outils des politiques climat-air-énergie régionales apparaissent comme essentiels dans le positionnement central de la Région : le schéma régional du climat, de l’air et de l’énergie (SRCAE), d’une part, présenté comme le vecteur d’une approche intégrée, et le chef de filât des Régions en matière de climat, d’air et d’énergie, d’autre part. La logique qui préside à ses outils et les usages qui en sont faits permettent d’avancer l’idée d’une Région Île-de-France de plus en plus au centre du jeu sur les enjeux de climat, d’air et d’énergie. / The rising power of regions seems obvious in academic literature in France and abroad. What is the contribution of emerging issues such as environment to this shift? Is there such an increasing power of regions in the climate, air, and energy field? If so, how does it happen? To answer these questions, this doctoral thesis focuses on the changing role of the Île-de-France regional council in climate, air and energy policies since the 90’s. The study highlights an increase in power of the Île-de-France Region (also known as « Paris Region ») to address climate, air, and energy issues. This Region has taken a major position among all stakeholders. This observation has been made possible through a combination of a law and political sciences approaches. It allowed to study the actors, their relationships, their area of competence, their constraints, their means, and the way they use it. We studied in this doctoral thesis the jurisdiction of the Île-de-France regional council, its human and financial resources, its positioning regarding other actors in the region, and the way the regional council uses legal rules. Two schemes seem to be essential to understand the increasingly central position of the Île-de-France regional council on climate, air, and energy questions: first, the climate, air, and energy regional plan (schéma régional du climat, de l’air et de l’énergie) and then the chef de file (which could be translate by “leadership role”) of regional councils.

Sexual Violence, Identity Centrality, And Mental Health Among Racial And Sexual Minoritized Individuals: An Application Of Cultural Betrayal Trauma Theory

Coolidge, Brettland D 01 January 2023 (has links) (PDF)
Sexual violence (SV) is a pressing concern in the United States. SV (i.e., unwanted sexual contact, coercion, and wanted or unwanted penetration of another). Individuals with minoritized sexual, racial/ethnic, and gender identities experience worse psychosocial outcomes than their majority counterparts. People with multiple marginalized identities have been shown to experience traumatic events at greater rates and with significantly different outcomes compared to those with one minoritized identity. Cultural betrayal trauma theory proposes that these differences in mental health outcomes may be explained in part by a shared cultural identity between a SV perpetrator and victim, which is posited to exacerbate mental health symptomology. This study's sample consisted of 276 participants who were over the age of 18 and identified with both minoritized sexual and racial/ethnic identities. Results of this study failed to support most of the study's hypotheses yet confirmed that increase in mental health symptomology is associated with SV experience. This study indicates that research of cultural betrayal trauma may necessitate a more nuanced approach among individuals with multiple marginalized identities.

Efficient betweenness Centrality Computations on Hybrid CPU-GPU Systems

Mishra, Ashirbad January 2016 (has links) (PDF)
Analysis of networks is quite interesting, because they can be interpreted for several purposes. Various features require different metrics to measure and interpret them. Measuring the relative importance of each vertex in a network is one of the most fundamental building blocks in network analysis. Between’s Centrality (BC) is one such metric that plays a key role in many real world applications. BC is an important graph analytics application for large-scale graphs. However it is one of the most computationally intensive kernels to execute, and measuring centrality in billion-scale graphs is quite challenging. While there are several existing e orts towards parallelizing BC algorithms on multi-core CPUs and many-core GPUs, in this work, we propose a novel ne-grained CPU-GPU hybrid algorithm that partitions a graph into two partitions, one each for CPU and GPU. Our method performs BC computations for the graph on both the CPU and GPU resources simultaneously, resulting in a very small number of CPU-GPU synchronizations, hence taking less time for communications. The BC algorithm consists of two phases, the forward phase and the backward phase. In the forward phase, we initially and the paths that are needed by either partitions, after which each partition is executed on each processor in an asynchronous manner. We initially compute border matrices for each partition which stores the relative distances between each pair of border vertex in a partition. The matrices are used in the forward phase calculations of all the sources. In this way, our hybrid BC algorithm leverages the multi-source property inherent in the BC problem. We present proof of correctness and the bounds for the number of iterations for each source. We also perform a novel hybrid and asynchronous backward phase, in which each partition communicates with the other only when there is a path that crosses the partition, hence it performs minimal CPU-GPU synchronizations. We use a variety of implementations for our work, like node-based and edge based parallelism, which includes data-driven and topology based techniques. In the implementation we show that our method also works using variable partitioning technique. The technique partitions the graph into unequal parts accounting for the processing power of each processor. Our implementations achieve almost equal percentage of utilization on both the processors due to the technique. For large scale graphs, the size of the border matrix also becomes large, hence to accommodate the matrix we present various techniques. The techniques use the properties inherent in the shortest path problem for reduction. We mention the drawbacks of performing shortest path computations on a large scale and also provide various solutions to it. Evaluations using a large number of graphs with different characteristics show that our hybrid approach without variable partitioning and border matrix reduction gives 67% improvement in performance, and 64-98.5% less CPU-GPU communications than the state of art hybrid algorithm based on the popular Bulk Synchronous Paradigm (BSP) approach implemented in TOTEM. This shows our algorithm's strength which reduces the need for larger synchronizations. Implementing variable partitioning, border matrix reduction and backward phase optimizations on our hybrid algorithm provides up to 10x speedup. We compare our optimized implementation, with CPU and GPU standalone codes based on our forward phase and backward phase kernels, and show around 2-8x speedup over the CPU-only code and can accommodate large graphs that cannot be accommodated in the GPU-only code. We also show that our method`s performance is competitive to the state of art multi-core CPU and performs 40-52% better than GPU implementations, on large graphs. We show the drawbacks of CPU and GPU only implementations and try to motivate the reader about the challenges that graph algorithms face in large scale computing, suggesting that a hybrid or distributed way of approaching the problem is a better way of overcoming the hurdles.
