Children with attention-deficit/hyperactivity disorder (ADHD) experience frequent and persisting peer rejection, yet current social skills training is ineffective. The current study focused on emotion dysregulation as a possible mediator between ADHD symptoms and poor peer outcomes with oppositional defiant disorder (ODD) symptoms as a moderator. Participants included 145 elementary-age children ranging from 8-10 years old. Parents and teachers rated children’s ADHD and ODD symptoms as well as their social skills. Parents also rated children on their emotion regulation abilities. Children then participated in a three-hour playgroup with unfamiliar peers in six structured and unstructured tasks. Research assistants provided global ratings of emotion regulation and peer rejection during each of the six tasks. At the end of the playgroup, children and staff completed sociometric questions about each child. Using multiple raters and methods, observed emotion regulation was found to mediate between increased symptoms of ADHD and worse peer relations as rated by the playgroup staff members. There were limited findings of significant moderation by ODD. Emotion dysregulation may be a valuable target for intervention in order to improve peer relations for children with ADHD.

Neste trabalho, foi proposta uma nova família de distribuições, a qual permite modelar dados de sobrevivência quando a função de risco tem formas unimodal e U (banheira). Ainda, foram consideradas as modificações das distribuições Weibull, Fréchet, half-normal generalizada, log-logística e lognormal. Tomando dados não-censurados e censurados, considerou-se os estimadores de máxima verossimilhança para o modelo proposto, a fim de verificar a flexibilidade da nova família. Além disso, um modelo de regressão locação-escala foi utilizado para verificar a influência de covariáveis nos tempos de sobrevida. Adicionalmente, conduziu-se uma análise de resíduos baseada nos resíduos deviance modificada. Estudos de simulação, utilizando-se de diferentes atribuições dos parâmetros, porcentagens de censura e tamanhos amostrais, foram conduzidos com o objetivo de verificar a distribuição empírica dos resíduos tipo martingale e deviance modificada. Para detectar observações influentes, foram utilizadas medidas de influência local, que são medidas de diagnóstico baseadas em pequenas perturbações nos dados ou no modelo proposto. Podem ocorrer situações em que a suposição de independência entre os tempos de falha e censura não seja válida. Assim, outro objetivo desse trabalho é considerar o mecanismo de censura informativa, baseado na verossimilhança marginal, considerando a distribuição log-odd log-logística Weibull na modelagem. Por fim, as metodologias descritas são aplicadas a conjuntos de dados reais. / In this study, a new family of distributions was proposed, which allows to model survival data when the function of risk has unimodal shapes and U (bathtub). Modifications of the Weibull, Fréchet, generalized half-normal, log-logistic and lognormal distributions were considered. Taking censored and non-censored data, we consider the maximum likelihood estimators for the proposed model, in order to check the flexibility of the new family. Also, it was considered a location-scale regression model, to verify the influence of covariates on survival times. Additionally, a residual analysis was conducted based on modified deviance residuals. For different parameters fixed, percentages of censoring and sample sizes, several simulation studies were performed with the objective of verify the empirical distribution of the martingale type and modified deviance residuals. To detect influential observations, measures of local influence were used, which are diagnostic measures based on small perturbations in the data or in the proposed model. It can occur situations in which the assumption of independence between the failure and censoring times is not valid. Thus, another objective of this work is to consider the informative censoring mechanism based on the marginal likelihood, considering the log-odd log-logistic Weibull distribution in modelling. Finally, the methodologies described are applied to sets of real data.

Propor uma família de distribuição de probabilidade mais ampla e flexível é de grande importância em estudos estatísticos. Neste trabalho é utilizado um novo método de adicionar um parâmetro para uma distribuição contínua. A distribuição gama generalizada, que tem como casos especiais a distribuição Weibull, exponencial, gama, qui-quadrado, é usada como distribuição base. O novo modelo obtido tem quatro parâmetros e é chamado odd log-logística gama generalizada (OLLGG). Uma das características interessante do modelo OLLGG é o fato de apresentar bimodalidade. Outra proposta deste trabalho é introduzir um modelo de regressão chamado log-odd log-logística gama generalizada (LOLLGG) com base na GG (Stacy e Mihram, 1965). Este modelo pode ser muito útil, quando por exemplo, os dados amostrados possuem uma mistura de duas populações estatísticas. Outra vantagem da distribuição OLLGG consiste na capacidade de apresentar várias formas para a função de risco, crescente, decrescente, na forma de U e bimodal entre outras. Desta forma, são apresentadas em ambos os casos as expressões explícitas para os momentos, função geradora e desvios médios. Considerando dados nãocensurados e censurados de forma aleatória, as estimativas para os parâmetros de interesse, foram obtidas via método da máxima verossimilhança. Estudos de simulação, considerando diferentes valores para os parâmetros, porcentagens de censura e tamanhos amostrais foram conduzidos com o objetivo de verificar a flexibilidade da distribuição e a adequabilidade dos resíduos no modelo de regressão. Para ilustrar, são realizadas aplicações em conjuntos de dados reais. / Providing a wider and more flexible probability distribution family is of great importance in statistical studies. In this work a new method of adding a parameter to a continuous distribution is used. In this study the generalized gamma distribution (GG) is used as base distribution. The GG distribution has, as especial cases, Weibull distribution, exponential, gamma, chi-square, among others. For this motive, it is considered a flexible distribution in data modeling procedures. The new model obtained with four parameters is called log-odd log-logistic generalized gamma (OLLGG). One of the interesting characteristics of the OLLGG model is the fact that it presents bimodality. In addition, a regression model regression model called log-odd log-logistic generalized gamma (LOLLGG) based by GG (Stacy e Mihram, 1965) is introduced. This model can be very useful when, the sampled data has a mixture of two statistical populations. Another advantage of the OLLGG distribution is the ability to present various forms for the failing rate, as increasing, as decreasing, and the shapes of bathtub or U. Explicity expressions for the moments, generating functions, mean deviations are obtained. Considering non-censored and randomly censored data, the estimates for the parameters of interest were obtained using the maximum likelihood method. Simulation studies, considering different values for the parameters, percentages of censoring and sample sizes were done in order to verify the distribuition flexibility, and the residues distrbutuon in the regression model. To illustrate, some applications using real data sets are carried out.

By exploring this game, we analyze a dispute between two players, one being a strategist and another layman. In the rst part were successive bets, in which the strategist had advantage over the layman. Then play until someone stay without money. The methodology is investigative and directed by activities that seek to show the importance of this knowledge in cognitive training of the student, giving it a theoretical re ection on the practice experienced and stimulating logical reasoning mathematical experiences. The work was divided into parts. Before starting the detail work, we use a theoretical basis directed to Game Theory and Probability. In the course of this, we present the relevant problems of work results. Shortly following section, we have four draft classes using the game of odd or even. One of which was performed at the High School students. / O trabalho a seguir, foi realizado em cima do Jogo do Par ou Ímpar. Ao explorar esse jogo, analisamos uma disputa entre dois jogadores, sendo um deles estrategista e o outro leigo. Na primeira parte consideramos sucessivas apostas, nais quais, o estrategista tem vantagem probabilística sobre o leigo. Depois, consideramos o caso onde os jogadores jogam até que alguém que sem dinheiro. A metodologia é investigativa e direcionada por atividade que buscam mostrar a importância desse conhecimento na formação cognitiva do aluno, propiciando-lhe uma re exão teórico-prática acerca das experiências vivenciadas e estimulando o raciocínio lógico matemático. O trabalho foi dividido em partes. Antes de iniciar o detalhamento do trabalho, usamos um embasamento teórico direcionado a Teoria dos Jogos e a Probabilidade. No desenrolar deste, apresentamos resultados pertinentes a problemática do trabalho. Logo em seguida, temos quatro propostas de aulas utilizando o jogo do Par ou Ímpar. Sendo que uma delas foi executada aos alunos do Ensino Médio.

FundaÃÃo Cearense de Apoio ao Desenvolvimento Cientifico e TecnolÃgico / A presente pesquisa teve como objetivo analisar as configuraÃÃes do âbicoâ de policiais militares da cidade de Fortaleza na seguranÃa privada. Foi realizado um panorama dessa atividade que possibilitou enumerar trÃs caracterÃsticas recorrentes do bico em Fortaleza, tais como: as atividades de seguranÃa em estabelecimentos comerciais (casas de show, barracas de praia, restaurantes, salÃo de beleza, mercadinhos, dentre outros), seguranÃa particular (de empresÃrios ou comerciantes) e, por Ãltimo, o âbico veladoâ (fazer policiamento privado em horÃrio de serviÃo, concedendo, nesse sentido, maior atenÃÃo a determinados pontos comerciais). O trabalho revelou que essa prÃtica, em Fortaleza, Ã sustentada tanto por parte dos oficiais militares como pelos PraÃas, e mostrou que ambos formam redes de intermediÃrios ou atravessadores que vendem seguranÃa, principalmente, para empresÃrios e comerciantes. A pesquisa abordou tambÃm a estreita relaÃÃo entre a violÃncia e a expansÃo do bico na cidade, denunciando o reforÃo de uma cultura do medo pautada no sentimento de inseguranÃa. Por fim, o trabalho tratou das implicaÃÃes dessa atividade para os policiais militares em decorrÃncia do CÃdigo Disciplinar e de Ãtica da referida corporaÃÃo. A dissertaÃÃo trabalhou, ainda, com a relaÃÃo entre precariedade do trabalho policial e do trabalho na atividade de seguranÃa privada. / The present reseach has the aim of analyzing the configuration of odd jobs on private security of military policemen in the city of Fortaleza. With this in mind, a panorama of this activity was traced in order to enumerate the three recurrent characteristics of the odd jobs in Fortaleza, such as: security activities icommercial establishments (concert houses, beach huts, restaurants, beauty salons, markets, among others), private security (of businessmen or merchants) and, finally, the veiled odd job (to perform private patrolling while on duty, giving more attention to specific commercial points). The work revealed that this practice in Fortaleza is sustained both by the military officers and the privates and showed that both form networks of intermediaries or middlemen who sell security to businessmen or merchants. The research also dealt with the strict relationship between violence and the expansion of odd jobs through the city, denouncing the intensification of a culture of fear based on the feeling of insecurity. At last, the work dealt with the implications of this activity for military policemen due to their disciplinary and ethics code. The discussion ended also with the relationship between the precariousness of the police work and the work on private security.

This thesis discloses my exploration of non-isochronous meters through composition and practice. During my two-year studies at the Royal College of Music in Stockholm, I explored different unevenly divided time signatures by practicing them in various ways, producing transcriptions, compositions and arrangements.The main purpose of this project was to further my knowledge and skills within these time signatures and thereby expand my horizon on perceiving, conceptualizing, composing and playing them. My endeavors culminated in seven original compositions, arranged for a jazz sextet, which I rehearsed and performed with an ensemble. During the process of composing, arranging, practicing and rehearsing, I gained a lot of articulated knowledge as well as embodied knowledge of the idiosyncrasies of various non-isochronous meters and different ways to perceive and play them.

Yes / This work presents a combination of a cup-shaped monopole antenna and an E-shaped Multi-Mode Resonator (MMR) with the presence of a pair of PIN diodes and a varactor diode to form a compact reconfigurable communication filtering antenna for interweave Cognitive Radio (CR) systems. The proposed filtering antenna operates in the WiMAX band, and it is fabricated on an FR4 substrate with overall dimensions normalized to the wavelength ( λ o ) of the first resonant frequency (0.413λ o × 0.516λ o × 0.0165λ o ). The step and continuous tuning serve the secondary user of the WiMAX CR system to communicate in the absence of the primary users at modifiable resonant frequencies and data rates.When the PIN diodes are OFF, the filtering antenna operates with a fixed odd mode resonant frequency and tunable even mode resonant frequency. This state results in a tunable antenna bandwidth covering a maximum measured frequency range of 3.25-4.02~ GHz and a minimum measured range equal to 3.25-3.58~ GHz. The ON state of the PIN diodes eliminates the antenna matching at the even mode resonant frequency while keeping a strong matching at the odd mode resonant frequency. The resulted operational measured frequency range of the antenna in this state is fixed at 2.9-3.28~ GHz. The filtering antenna has acceptable gain values at the pass band of the E-shaped MMR with a maximum simulated gain value equal to 2.5~ dB and a measured maximum gain equal to 2.48~ dB. The simulated and measured power patterns of the antenna for all diodes states are omnidirectional, which are convenient for portable CR gadgets. / This work was supported in part by the Innovation Programme under Grant H2020-MSCA-ITN-2016 SECRET-722424, and in part by the U.K. Engineering and Physical Sciences Research Council (EPSRC) under Grant EP/E022936/1.
